 We also sell products into other markets such as the HDTV and PC-based add-in markets.  We derive minor revenue from sales of our products into these other markets.

We have been providing video and audio semiconductor solutions for over 15 years.  We began volume shipments in January 2006 of our SMP8630 series, our fourth generation SoC solution serving the IPTV, connected media player and HDTV markets and began shipments of our next generation SMP8650 series in January 2009.  Volume shipments of our acquired HPNA connectivity solutions began in 2006.  Volume shipments of our acquired VXP solutions began in 2003.

Industry Background

The growth of the internet, proliferation of rich multimedia content, advances in communications infrastructure, digital video and audio compression technologies, home networking technologies, and improvements in television displays have resulted in significant demand for our products in the markets that we primarily target, which are the IPTV media processor, connected home, connected media player and prosumer and industrial audio/video.

Our IPTV media processor target market is driven by service providers, primarily telecommunication service providers, who utilize video servers and set-top box clients to deliver television services based on streaming video over broadband connections using IP.  IPTV has emerged as an important consumer multimedia application as it allows telecommunications carriers to deliver advanced video services to consumers using existing telecommunications infrastructure.  These carriers are actively pursuing the deployment of IPTV because it enables them to offer attractive video, voice and data, or triple play, services and increase their revenue per subscriber.  The key challenge faced in delivering high-quality video content to end users across existing copper-based telecommunications infrastructure is the limited data carrying capacity of the existing wiring.  This challenge is addressed by advanced video compression technologies along with advanced high speed communication technologies, which together overcome the capacity limitation to allow the delivery of high definition video service throughout the home.  IPTV set-top boxes currently use one of three platforms based on software developed by Microsoft or various Android and Linux providers each of which offers certain advantages and disadvantages.

6

In our connected home target market, devices are involved in routing digital entertainment streams to ensure that television service and other shared media resources are accessible throughout the home.  Currently, the vast majority of home networking uses wired connections to distribute entertainment streams under one of the many standards that exist.  As consumers begin to demand more from their viewing experience, we believe the ability to deliver these technologies within the home will be critical to a successful solution.  Home control products enable remote control and monitoring of a wide variety of home appliances, such as thermostats, lighting and door locks.  Our home control and energy management automation products and Z-wave protocol continue to experience increasing consumer awareness and adoption, although current worldwide penetration rates remain low.  Much of the early adoption for this technology has come from usage in new home construction.  We believe potential deployment by an increasing number of larger system integrators and service providers in the future could drive a cycle of broader adoption.  The functionality provided by the low frequency, low power solutions in this market can offer consumers cost efficient ways to monitor and conserve energy usage, protect homes from theft and damage and improve the convenience of performing certain household activities.

In our connected media player market we believe the demand for DMAs is continuing to gradually increase as these products become easier for consumers to use and increased bandwidth within homes facilitates movie downloading.  The increased demand for Blu-ray DVD players is driven primarily by the superior video and audio quality they provide relative to standard definition DVD players, the increasing availability of high definition prerecorded content, the proliferation of HDTVs enabling display of this content and the steadily declining prices of the Blu-ray DVD players and the HDTVs themselves.  Portable players remain popular in selected foreign markets, but have yet to gain popularity in the U.S.

In our prosumer and industrial audio/video market we believe demand for improved video image processing continues to increase from both industrial customers and consumers focused on high-end products, or prosumers.  These industrial and prosumer customers are increasingly expecting high-definition images, DVD content that looks like high-definition, and high quality online images.  As a result, we believe standalone and integrated video image processors are likely to be incorporated into an increasing number of video-centric products over time.

The proliferation of HDTVs is being driven by consumer demand for higher quality video, increasing availability of higher definition content, improved television displays, declining prices and various mandates to shift from analog to digital broadcast worldwide.  This is creating an opportunity for SoC suppliers to provide technology that enables consumers to enjoy multi-format content on their HDTVs including content from internet, stored video sources and Blu-ray players.

The consumer multimedia entertainment applications that we target increasingly require video and audio data to be processed, transmitted, stored and displayed in an efficient and secure manner while simultaneously maintaining high resolution, multi-channel video and audio and providing the end-user a variety of interactive options.  In order to provide this increased functionality in a cost-effective manner, manufacturers of consumer electronics demand semiconductors that integrate more features on a single chip as well as reduce their costs, time-to-market and power consumption.  We believe the challenge to manufacturers of digital media processor SoCs is to balance the integration of more functionality with lower costs and shorter development cycles.

Our Solutions

Our SoC solutions consist of highly integrated semiconductors and software that enables real-time processing of digital video and audio content, which we refer to as real-time software.  Our real-time software is readily customizable by our customers and is interoperable with multiple standard operating systems.  As a result, we believe our SoC solutions enable our customers to efficiently bring consumer multimedia devices to market.  We believe IPTV set-top box and connected media player designers and consumer device manufacturers select our SoC solutions because of their high performance and ease of integration.  Our highly integrated products have replaced a number of single function semiconductors with a multi-function SoC, which significantly improves performance and lowers power consumption and total system cost.

We believe our media processor SoCs have been able to deliver industry-leading performance in video decoding, graphics acceleration and audio decoding, which allows our customers to offer consumers a high-quality viewing experience.  We surround this media processing functionality with a robust security management solution, an on-chip CPU, a high-speed memory interface and complementary system peripherals.  Our VXP SoCs represent a line of video image processors that complement this core capability with studio-quality video.  Our VXP devices can be used by our customers either as standalone products or in combination with products that we sell into our other target markets, such as our SoCs for IPTV, connected media players and HDTV.  We recently introduced our SMP8910 SoC which integrates our VXP technology and our media processor technology in one SoC. 

Our SoC architecture with memory components establishes a complete hardware development platform for our target applications.  We also offer a suite of real-time software that reduces the complexity of our SoC architecture and enables our customers to efficiently design consumer multimedia devices.  Our software includes an industry standard operating system, embedded software tools and development kits that enable our customers to efficiently port their software to run on our processors.

Our wired and wireless home networking SoCs are designed to provide connectivity solutions between various home entertainment products and incoming video/audio streams.  We believe these connectivity solutions give consumers additional connection choices with greater flexibility and allow system integrators and service providers an opportunity to reduce their time and cost of home networking installations.

7

Our wireless Z-Wave SoCs are designed to offer consumers advanced home control and energy management automation functionality, such as home security, environmental and energy control and monitoring, within both new and existing homes.

Our Strengths

We have developed or acquired the core technologies, expertise and capabilities necessary to provide a complete SoC solution or platform that includes media processing, communications and control.  We believe we have the following strengths:

• Strong Position within IPTV Media Processor and Connected Media Player Markets.  We believe we are the leading provider of digital media processor SoCs for set-top boxes in the IPTV market in terms of units shipped and a high quality provider of such SoCs in the connected media player market.  We have built this position, in part, by being one of the first media processing semiconductor providers to work extensively with IPTV set-top box manufacturers as well as telecommunications carriers to design solutions that address their specific feature and performance requirements.  Additionally, through our CopperGate acquisition, we have a team that delivers the leading IPTV connectivity solution for set-top boxes and residential gateways.  Through this process, we have gained valuable insight into the challenges of our customers and carriers and have gained visibility into their product development plans.  As a result, we believe we are able to provide our customers with a stable and reliable source of field-proven solutions that our competitors cannot easily replicate.

• Highly Integrated SoC Leveraged Across Multiple Consumer Applications.  We have developed a proprietary SoC architecture that allows us to integrate high-performance digital video and audio decoding, graphics processing, security management and home audio/video networking and advanced image processing.  Our SoCs can replace a number of single function semiconductors, which significantly improves performance and lowers power consumption and total system cost to our customers.  Furthermore, all of these functions can be performed synchronously at high processing speeds, typically beyond 400 Megahertz.  Our ability to integrate these multiple functions into a single, high-speed semiconductor allows us to address many different consumer multimedia entertainment applications with the same hardware platform.

• Differentiated Software Development Capabilities.  As a result of our over 15 years of experience in delivering video and audio solutions, we have developed expertise in real-time software that synchronizes and controls the playback of video and audio from a variety of sources.  This software translates the complex silicon architecture of our SoCs into a much simpler application programming interface.  Using this interface, our customers are able to program under industry standard operating systems, enabling them to easily customize our solutions and reduce their time to market.  The majority of our engineering personnel are dedicated to software development.

• Multi-Standard Functionality.  Our SoC solutions are designed to support multiple industry standards that are used in the consumer applications we target.  For example, there are over a dozen different video and audio standards used in current consumer applications, including video standards such as H.264, MPEG-4, MPEG-2, MPEG-1 and WMV9, and audio standards such as Dolby, DTS and MP3.  Beyond this, there are a range of digital rights management security standards such as AES, RSA and MSDRM.  Additionally, there are three primary operating systems, Android, Linux and Microsoft Windows CE, each of which has its own middleware standards.  We support all of these standards.

• Breadth and Depth of Relationships within the set-top box industry and IPTV Ecosystem.  In order to provide a complete system-level solution for the IPTV market, we have developed strong relationships with industry leaders that form the ecosystem required to deliver an end-to-end solution, from content creation to content display.  The IPTV ecosystem consists of providers of middleware, encoders and security solutions.  For middleware, server software must be successfully integrated into our products to provide effective system solutions for the service providers.  For encoders, providers such as Harmonic, Tandberg and Modulus Video (now part of Motorola) must design products that operate compatibly with digital media processors such as ours.  For security solutions, there are also a range of providers, including Microsoft, Nagra and NDS.  Our strong position in the IPTV market has enabled us to develop and maintain relationships with these providers and offer solutions that are interoperable with their products.

• Multi-function Technology Addressing the Set-top Box Market:   We offer a broad range of products that address the set-top box market.  Various manufacturers and service providers have expanded the functionalities that are included within set-top box specifications to include wired and wireless home networking and home control and energy management products.  We believe we are well-positioned to offer solutions or platforms for each of these three technologies. Furthermore, we are in the process of integrating our VXP technology into our future media processor solutions which will allow us to enable studio-quality video output in the home.

Our Strategy

Our objective is to be the leading provider of SoC solutions used to deliver entertainment and control throughout the home.  To achieve this objective, we expect to continue to pursue the following strategies:

• Maintain our Leadership Position in the IPTV Media Processor Market.  We have achieved a significant share in the IPTV media processor market by providing our customers with highly integrated digital media processor SoCs as well as high bandwidth network devices that provide the home connectivity.  In addition, our solutions work effectively across different platforms and standards in this market.  Furthermore, we intend to target some of the largest cable multiple system operators as a part of their anticipated technology transition to tru2way and IPTV delivery.  Tru2way is a trademark of CableLabs, which is used to describe the delivery of interactive digital cable services over the cable video network.  We intend to provide the most compelling integrated digital media processing solutions to our customers and support multiple standards in this end market in order to maintain our strong market share in the IPTV market as well as extend our product strengths into the next generation of set-top boxes for the cable industry.

• Enhance our Software Advantage.  We believe our software provides a suite of capabilities that are not currently available from our competitors.  Our software is integrated and embedded into our customers' products during their product design stage.  As a result, once we are designed into our customers' product, we believe it is difficult for our competitors to displace us.  We intend to leverage our software development capabilities and continue to invest significant resources in recruiting and developing additional expertise in the area of high-performance software development and customer support.

• Increase Penetration in Connected Media Players.  We have successfully developed a strong position in the digital media adapter market as well as other related consumer products.  Our SoC solutions incorporate both hardware and software elements that enable access to internet content and interoperability with a wide range of software environments such as Adobe Flash, Google Android, Netflix and many others.  We believe our software, which fully supports the various standards and technologies required to provide internet connectivity and networking functionality, differentiates us from our competitors.  We intend to leverage our semiconductor and software expertise to develop additional SoC solutions targeted specifically towards this growing range of applications.

• Expand our position in the Connected Home Market. We have developed unified broadband home networking technology under the G.hn standard.  We plan to use this technology to further expand our position in the connected home market. This market is fragmented into multiple standards, and we believe G.hn provides a way of unifying the demand in this market under a single standard encompassing all wired transmission media (coaxial cable, phone line and power line) in the home.  We believe that G.hn will meet or exceed performance requirements for higher throughput, reliability and robustness for next generation networked products.  We intend to expand our position with our Z-wave technology from home control to energy management automation and service provider offered value-added services, such as home monitoring, home security and remote access and control and remote health management.

• Expand into Complementary Technologies and Products.  We will continue to evaluate opportunities to expand, whether through acquisition or internal development, into technologies and products that are complementary to the applications we currently target.  In November 2009, we acquired CopperGate, a privately held company in Israel that develops silicon-based home networking solutions enabling distribution of media-rich digital content over phone lines, coaxial cables and power lines inside the home.  In December 2008, we acquired Zensys Holdings Corporation, a privately held company that developed the Z-Wave brand of RF devices for home control and energy management automation that have demonstrated the ability to grow our home connectivity market.  We believe that the Z-Wave products will enable us to offer another layer to our value proposition to telecommunications and cable operators, thus helping us to differentiate our complete solution as competition in the marketplace increases.  In February 2008, we acquired certain assets of the VXP Group from Gennum Corporation.  We recently introduced the SMP8910 media processor, our first product to incorporate the VXP image processing technology to expand into the professional video market and add broadcast studio quality capability to our product offerings for high-volume consumer applications in IPTV set-top boxes, connected media players and HDTVs.  In 2006, we acquired Blue7, a developer of advanced UWB technologies, in order to extend our product offerings into wireless solutions for the home entertainment environment.  We believe that the combination of wireless communication technologies with our existing media processing SoC solutions will enable us to increase the value we deliver to our customers.

9

Customers

We sell our products principally to designers and manufacturers and to distributors who, in turn, sell to manufacturers.  Typically, when we sell to distributors, they have already received an order for our products directly from a manufacturer.  Our sales to our customers are typically accomplished on a purchase order basis.

For fiscal 2011, Motorola and Gemtek accounted for 24% and 23%, respectively, of our net revenue. For fiscal 2010, Motorola and Gemtek accounted for 21% and 12%, respectively, of our net revenue.  For fiscal 2009, Motorola and Cisco Systems accounted for 21% and 16%, respectively, of our net revenue.  

A substantial portion of our product shipments are to customers outside of North America.  In fiscal 2011, 2010 and 2009, net revenue from our customers outside of North America accounted for 95%, 97% and 88% of our net revenue, respectively.  Revenue from our customers in Asia accounted for 93%, 89% and 76% of our net revenue in fiscal 2011, 2010 and 2009, respectively.

Sales and Marketing

We sell our products worldwide through multiple channels, including our direct sales force, manufacturer representatives and independent distributors strategically located in many countries around the world.  Members of our direct sales force are based in the United States, Denmark, France, Hong Kong, Israel, Taiwan and Singapore.  Our sales are also supported by representatives, resellers and distributors in other key markets such as Brazil, China, India, Japan and Korea.

Our sales cycle typically ranges from nine to eighteen months, but may last longer, and depends on a number of factors including the technical capabilities of the customer, the customer's need for customization of our SoCs and the customer's evaluation and qualification process.  We generally plan the fabrication of our products based on customer forecasts.

For our larger volume designer and manufacturer customers, purchase orders for our products are generally non-cancelable between four and twelve weeks before our scheduled delivery dates and not subject to rescheduling within four weeks of scheduled delivery dates.

15

Competition

The market for digital media processors and network controller devices is highly competitive and is characterized by rapid technological change, evolving standards and decreasing average selling prices per unit.  We believe that the principal factors on which we compete include time-to-market for new product introductions, product performance, industry standards compatibility, software functionality, image quality, price, product support and marketing and distribution resources.

We believe our primary competitors include Broadcom Corporation, Intel, Mediatek, RealTek, ST Microelectronics and Trident for our media processors; Broadcom (through their acquisition of Gigle), Lantiq (through their acquisition of Aware), Marvell (through the acquisition of DS2) and Qualcomm (through their acquisition of Atheros) for our HPNA and HPAV products; Texas Instruments, Freescale and Ember through their Zigbee based chips for our Z-Wave products; and IDT and Marvell for our VXP products.  Many of these companies have higher profiles, larger financial resources and greater marketing resources than we do and may develop a competitive product that may inhibit the wide acceptance of our products.  We believe that other manufacturers are developing products that will compete directly with our products in the near future.

Research and Development

We focus our development efforts primarily on four areas: video/audio decoder technologies, secure media processing, home connectivity and fully integrated SoC solutions.  To achieve and maintain technology leadership, we intend to continue to make advancements in the areas of video and audio compression and decompression as well as wired and wireless connectivity.  We expect these advancements will include maintaining compatibility with emerging standards and multiple platforms, and making improvements to the current architecture.

We have invested, and expect that we will continue to invest, substantial resources to research and development of performance enhancements, cost reductions and additional features for future generations of Motion Picture Expert Group, or MPEG, and other multimedia technologies.  During fiscal 2011, 2010 and 2009, our research and development expenses were $77.3 million, $52.6 million and $43.6 million, respectively.

We have assembled a large team of experienced engineers and technologists.  As of January 29, 2011, we had 396 research and development employees.  These personnel conduct all of our product development along with the assistance of a number of independent contractors and consultants.

Intellectual Property

Our success and future revenue growth depend, in part, on our ability to protect our intellectual property.  We rely primarily on patent, copyright, trademark and trade secret laws as well as agreements with customers, suppliers and employees to protect our proprietary technologies and processes.

As of January 29, 2011, we held 90 issued patents and we had 68 patent applications pending for our technology.  The expiration dates of these patents are within the next four to nineteen years.  We cannot assure you that more patents will be issued or that such patents, even if issued, or our existing patents, will provide adequate protection for our competitive position.  Although we intend to protect our rights vigorously, we cannot assure you that these measures will be successful.

Manufacturing

We are a fabless semiconductor company and we do not own or operate a fabrication, packaging or testing facility.  We depend on third-party vendors to manufacture, package and test our products.  By outsourcing manufacturing, we are able to avoid the costs associated with owning and operating our own manufacturing facility.  This allows us to focus our efforts on the design and marketing of our products.

Semiconductor fabrication

We rely on Taiwan Semiconductor Manufacturing Company, or TSMC, and United Microelectronics Corporation, or UMC, to fulfill the majority of our semiconductor fabrication needs, including SoC manufacturing.  We believe that our fabless manufacturing approach provides us with the benefits of superior manufacturing capability as well as flexibility to move the manufacturing, assembly and testing of our products to those vendors that offer the best capability at an attractive price.  Nevertheless, because we do not have a formal, long-term pricing agreement with our third-party manufacturers, our costs and services are subject to sudden price fluctuations based on the cyclical demand for semiconductors.

16

Assembly and test

Once our wafers have been manufactured, they are shipped from TSMC and our other third-party foundries to sort, assembly and test facilities where they are sorted, packaged and tested.  Generally, we store our sorted die in our die bank and only package the products for sale when we book an order.  We outsource all packaging and testing of our products to third-party assembly and test facilities, primarily to Advanced Semiconductor Engineering, Inc., or ASE, in Taiwan.  Our products are designed to use low-cost, standard packages and to be tested with widely available test equipment.

Quality assurance

We are committed to maintaining the highest level of quality in our products.  We have designed and implemented a quality management system that provides the framework for continual improvement of products, processes and customer service to ensure customer satisfaction.  We also rely on in-depth simulation studies, design review and verification during our design phase, bench testing to perform design validation, product reliability qualification to verify the product’s quality and manufacturing testing when the products are in production.  To ensure consistent product quality, reliability and yield, together with our manufacturing logistics partners, we closely monitor the production cycle by reviewing manufacturing process data from each wafer foundry and assembly subcontractor.  ASE, UMC and TSMC have been awarded ISO 9000 certificates.

Backlog

The amount of backlog at any date depends upon various factors, including the timing of the receipt of orders, fluctuations in orders of existing product lines and the introduction of any new product lines.  Accordingly, we believe that the amount of our backlog at any date is not a useful measure of our future sales.

Employees

As of January 29, 2011, we had 592 full-time employees worldwide, including 396 in research and development, 101 in sales and marketing, 75 in general and administration and 20 in operations and quality assurance.

Our future success will depend, in part, on our ability to continue to attract, retain and motivate highly qualified technical, marketing, engineering and management personnel who are in great demand.  Our employees are not represented by any collective bargaining unit and we have never experienced a work stoppage.  We believe that our employee relations are satisfactory.

ITEM 1A . RISK FACTORS

If any of the following risks actually occurs, our business, financial condition and results of operations could be harmed.  In that case, the trading price of our common stock could decline and you might lose all or part of your investment in our common stock.  The risks and uncertainties described below are not the only ones we face.  You should also refer to the other information set forth in this Form 10-K, including our consolidated financial statements and the related notes.  Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations.

Risks Related to Our Business and Our Industry

If we do not successfully anticipate market needs and develop products and product enhancements in a timely manner that meet those needs, or if those products do not gain market acceptance, we may not be able to compete effectively and our ability to generate revenue will suffer.

We may not be able to accurately anticipate future market needs or be able to develop new products or product enhancements to meet such needs or to meet them in a timely manner.  Our ability to develop and deliver new products successfully will depend on various factors, including our ability to:

• accurately predict market requirements and evolving industry standards;

• accurately design new SoC products;

• timely complete and introduce new product designs;

• timely qualify and obtain industry interoperability certification of our products and the equipment into which our products will be incorporated;

• ensure that our subcontractors have sufficient foundry, assembly and test capacity and packaging materials and achieve acceptable manufacturing yields;

• shift our products to smaller geometry process technologies to achieve lower cost and higher levels of design integration; and

• gain market acceptance of our products and our customers' products.

If we fail to anticipate market requirements or to develop new products or product enhancements to meet those needs in a cost-effective and timely manner, it could substantially decrease market acceptance and sales of our present and future products and we may be unable to attract new customers or retain our existing customers, which would significantly harm our business and financial results.

Even if we are able to anticipate, develop and commercially introduce new products and enhancements, our new products or enhancements may not achieve widespread market acceptance.  Any failure of our products to achieve market acceptance could adversely affect our business and financial results.

18

Our industry is highly competitive and we may not be able to compete effectively, which would harm our market share and cause our revenue to decline.

The markets in which we operate are extremely competitive and are characterized by rapid technological change, continuously evolving customer requirements and declining average selling prices.  We may not be able to compete successfully against current or potential competitors.  Most of our products compete with large semiconductor providers that have substantial experience and expertise in video, audio and multimedia technology and in selling to consumer equipment providers.  Many of these companies have substantially greater engineering, marketing and financial resources than we have.  As a result, our competitors may be able to respond better to new or emerging technologies or standards and to changes in customer requirements.  Further, some of our competitors are in a better financial and marketing position from which to influence industry acceptance of a particular industry standard or competing technology than we are.  Our competitors may also be able to devote greater resources to the development, promotion and sale of products, and may be able to deliver competitive products at a lower price.  We also may face competition from newly established competitors, suppliers of products based on new or emerging technologies and customers who choose to develop their own SoCs.  Additionally, some of our competitors operate their own fabrication facilities or may have stronger manufacturing partner relationships than we have.  We expect our current customers, particularly in the IPTV media processor and connected media player markets, to seek additional suppliers of SoCs for inclusion in their products, which will increase competition and could reduce our market share.  If we do not compete successfully, our market share and net revenue could decline.

If we fail to achieve initial design wins for our products, we may be unable to recoup our investments in our products and revenue could decline.

We expend considerable resources in order to achieve design wins for our products, especially our new products and product enhancements, without any assurance that a customer will select our product.  Once a customer designs a semiconductor into a product, it is likely to continue to use the same semiconductor or enhanced versions of that semiconductor from the same supplier across a number of similar and successor products for a lengthy period of time due to the significant costs and risks associated with qualifying a new supplier and potentially redesigning the product to incorporate a different semiconductor.  As a result, if we fail to achieve an initial design win in a customer's qualification process, we may lose the opportunity for significant sales to that customer for a number of its products and for a lengthy period of time, or we would only be able to sell our products to these customers as a second source, which usually means we would only be able to sell a limited amount of product to them.  Also, even if we achieve new design wins with customers, these manufacturers may not purchase our products in sufficient volumes to recoup our development costs, and they can choose at any time to stop using our products, for example, if their own products are not commercially successful.  This may cause us to be unable to recoup our investments in the development of our products and cause our revenue to decline.

We base orders for inventory on our forecasts of our customers' demand and if our forecasts are inaccurate, our financial condition and liquidity would suffer.

We place orders with our suppliers based on our forecasts of our customers' demand.  Our forecasts are based on multiple assumptions, each of which may introduce errors into our estimates.  When the demand for our customers' products increases significantly, we may not be able to meet demand on a timely basis and we may need to expend a significant amount of time working with our customers to allocate a limited supply and maintain positive customer relations.  If we underestimate customer demand, we may forego revenue opportunities, lose market share and damage our customer relationships.  Conversely, if we overestimate customer demand, we may allocate resources to manufacturing products that we may not be able to sell when we expect to or at all.  As a result, we would have excess or obsolete inventory, resulting in a decline in the value of our inventory, which would increase our cost of revenue and create a drain on our liquidity. 

We depend on a limited number of customers and any reduction, delay or cancellation of an order from these customers or the loss of any of these customers could cause our revenue to decline.

Our dependence on a limited number of customers means that the loss of a major customer or any reduction in orders by a major customer could materially reduce our net revenue and adversely affect our results of operations.  We expect that sales to relatively few customers will continue to account for a significant percentage of our net revenue for the foreseeable future.  We have no firm, long-term volume commitments from any of our major customers and we generally accept purchase commitments from our customers based upon their purchase orders.  Customer purchase orders may be cancelled and order volume levels can be changed, cancelled or delayed with limited or no penalties.  We have experienced fluctuations in order levels from period to period and expect that we will continue to experience such fluctuations and may experience cancellations in the future.  We may not be able to replace the cancelled, delayed or reduced purchase orders with new orders.  Any difficulty in the collection of receivables from key customers could also harm our business.

For fiscal 2011, Motorola and Gemtek accounted for 24% and 23%, respectively, of our net revenue.  For fiscal 2010, Motorola and Gemtek accounted for 21% and 12%, respectively, of our net revenue.  For fiscal 2009, Motorola and Cisco Systems accounted for 21% and 16%, respectively, of our net revenue.

19

Our business also depends on demand for our SoC solutions from companies, such as large telecommunication carriers, who are not our direct customers but deploy IPTV set-boxes that incorporate our SoC solutions.  Large carriers companies often use multiple set-top box providers, who in turn sometimes use multiple contract manufacturers to purchase our SoCs and manufacture set-top boxes.  Even though we do not sell our products directly to these companies that ultimately deploy set-top boxes to consumers, these companies have a significant impact on the demand for our SoC solutions.  For example, a significant number of our SoCs are incorporated into set-top boxes deployed by AT&T.  This significant concentration on AT&T set-top boxes was increased by our acquisition of CopperGate.  A significant percentage of the SoC solutions sold by CopperGate are also used in set-top boxes as well as gateways deployed by AT&T.  In the past, companies that deploy set-top boxes incorporating our SoC solutions have had significant fluctuations in demand which has resulted in a decline in our business from our direct customers, such as original equipment manufacturers and contract manufacturers.  Any decrease in the demand from the companies that deploy IPTV set-top boxes incorporating our SoC solutions, and in particular AT&T, could have a material and adverse effect on our net revenue and results of operation.

If demand for our SoCs declines or does not grow, we will be unable to increase or sustain our net revenue.

We expect our SoCs to account for a substantial majority of our net revenue for the foreseeable future.  For fiscal 2011, sales of our SoCs represented approximately 100% of our net revenue.  Even if the consumer electronic markets that we target continue to expand, manufacturers of consumer products in these markets may not choose to utilize our SoCs in their products.  The markets for our products are characterized by frequent introduction of new technologies, short product life cycles and significant price competition.  If we or our customers are unable to manage product transitions in a timely and cost effective manner, our net revenue would suffer.  In addition, frequent technological changes and introduction of next generation products may result in inventory obsolescence which would increase our cost of revenue and adversely affect our operating performance.  If demand for our SoCs declines or fails to grow or we are unable to develop new products to meet our customers' demand, our net revenue could be harmed.

The timing of our customer orders and product shipments can adversely affect our operating results and stock price.

Our net revenue and operating results depend upon the volume and timing of customer orders received during a given period and the percentage of each order that we are able to ship and recognize as net revenue during each period.  Customers may change their cycle of product orders from us, which would affect the timing of our product shipments.  Any failure or delay in the closing of orders expected to occur within a quarterly period, particularly from significant customers, would adversely affect our operating results.  Further, to the extent we receive orders late in any given quarter, we may not be able to ship products to fill those orders during the same period in which we received the corresponding order which could have an adverse impact on our operating results for that period.

We may face intellectual property claims that could be costly to defend and result in our loss of significant rights.

The semiconductor industry is characterized by frequent litigation regarding patent and intellectual property rights.  We believe that it may be necessary, from time to time, to initiate litigation against one or more third parties to preserve our intellectual property rights.  From time to time, we have received, and may receive in the future, notices that claim we have infringed upon, misappropriated or misused other parties' proprietary rights.  Any of the foregoing events or claims could result in litigation.  Any such litigation could result in significant expense to us and divert the efforts of our technical and management personnel.  In the event of an adverse result in any such litigation, we could be required to pay substantial damages, cease the manufacture, use and sale of certain products or expend significant resources to develop non-infringing technology or to obtain licenses to the technology that is the subject of the litigation, and we may not be successful in such development or in obtaining such licenses on acceptable terms, if at all.  In addition, patent disputes in the electronics industry have often been settled through cross-licensing arrangements.  Because we do not yet have a large portfolio of issued patents, we may not be able to settle an alleged patent infringement claim through a cross-licensing arrangement.

To remain competitive, we need to continue to transition our SoCs to increasingly smaller sizes while maintaining or increasing functionality, and our failure to do so may harm our business.

We periodically evaluate the benefits, on a product-by-product basis, of migrating to more advanced technology to reduce the size of our SoCs.  The smaller SoC size reduces our production and packaging costs, which enables us to be competitive in our pricing.  We also continually strive to increase the functionality of our SoCs, which is essential to competing effectively in our target markets.  The transition to smaller geometries while maintaining or increasing functionality requires us to work with our contractors to modify the manufacturing processes for our products and to redesign some products.  This effort requires considerable development investment and a risk of reduced yields as a new process is brought to acceptable levels of operating and quality efficiency.  In the past, we have experienced 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.  We may face similar difficulties, delays and expenses as we continue to transition our products to smaller geometry processes, all of which could harm our relationships with our customers, and our failure to do so would impact our ability to provide competitive prices to our customers, which would have a negative impact on our sales.

20

The complexity of our products could result in unforeseen delays or expenses and in undetected defects, which could damage our reputation with current or prospective customers, adversely affect the market acceptance of new products and result in warranty claims.

Highly complex products, such as those that we offer, frequently contain defects, particularly when they are first introduced or as new versions are released.  Our SoCs contain highly sophisticated silicon technology and complex software.  In the past we have experienced, and may in the future experience, defects in our products, both with our SoCs and the related software products we offer.  If any of our products contain defects or have reliability, quality or compatibility problems, our reputation may be damaged and our customers may be reluctant to buy our products, which could harm our ability to retain existing customers and attract new customers.  In addition, these defects could interrupt or delay sales or shipment of our products to our customers.  Manufacturing defects may not be detected by the testing process performed by our subcontractors.  If defects are discovered after we have shipped our products, it could result in unanticipated costs, order cancellations or deferrals and product returns or recalls, harm to our reputation and a decline in our net revenue, income from operations and gross margins.

In addition, our agreements with some customers contain warranty provisions, which provide the customer with a right to damages if a defect is traced to our products or if we cannot correct errors in our product reported during the warranty period.  However, any contractual limitations to our liability may be unenforceable in a particular jurisdiction.  We do not have insurance coverage for any warranty or product liability claims and a successful claim could require us to pay substantial damages.  A successful warranty or product liability claim against us, or a requirement that we participate in a product recall, could have adverse effects on our business results.

If our third-party manufacturers do not achieve satisfactory yields or quality, our relationships with our customers and our reputation will be harmed, which in turn would harm our operating results and financial performance.

The fabrication of semiconductors is a complex and technically demanding process.  Minor deviations in the manufacturing process can cause substantial decreases in yields and, in some cases, cause production to be stopped or suspended.  Although we work closely with our third-party manufacturers to minimize the likelihood of reduced manufacturing yields, their facilities have from time to time experienced lower than anticipated manufacturing yields that have resulted in our inability to meet our customer demand.  It is not uncommon for yields in semiconductor fabrication facilities to decrease in times of high demand, in addition to reduced yields that may result from normal wafer lot loss due to workmanship or operational problems at these facilities.  When these events occur, especially simultaneously, as happens from time to time, we may be unable to supply our customers' demand.  Many of these problems are difficult to detect at an early stage of the manufacturing process and may be time consuming and expensive to correct.  Poor yields from the wafer foundries or defects, integration issues or other performance problems in our products could cause us significant customer relations and business reputation problems or force us to sell our products at lower gross margins and therefore harm our financial results.

The average selling prices of semiconductor products have historically decreased rapidly and will likely do so in the future, which could harm our revenue and gross margins.

The semiconductor industry, in general, and the consumer electronics markets that we target, specifically, are characterized by intense price competition, frequent introductions of new products and short product life cycles, which can result in rapid price erosion in the average selling prices for semiconductor products.  A decline in the average selling prices of our products could harm our revenue and gross margins.  The willingness of customers to design our SoCs into their products depends to a significant extent upon our ability to sell our products at competitive prices.  In the past, we have reduced our prices to meet customer requirements or to maintain a competitive advantage.  Reductions in our average selling prices to one customer could impact our average selling prices to all customers.  If we are unable to reduce our costs sufficiently to offset declines in product prices or are unable to introduce more advanced products with higher margins in a timely manner, we could experience declines in our net revenue and gross margins.

We rely upon patents, trademarks, copyrights and trade secrets to protect our proprietary rights and if these rights are not sufficiently protected, it could harm our ability to compete and to generate revenue.

Our ability to compete may be affected by our ability to protect our proprietary information.  As of January 29, 2011, we held 90 patents and these patents will expire within the next four to nineteen years.  These patents cover the technology underlying our products.  We have filed certain patent applications and are in the process of preparing others.  We cannot assure you that any additional patents for which we have applied will be issued or that any issued patents will provide meaningful protection of our product innovations.  Like other semiconductor companies, we rely primarily on trade secrets and technological know-how in the conduct of our business.  We use measures such as confidentiality agreements to protect our intellectual property.  However, these methods of protecting our intellectual property may not be sufficient.

21

If the growth of demand in the consumer electronics market does not continue, our ability to increase our revenue could suffer.

Our business is highly dependent on developing sectors of the consumer electronics market, including IPTV media processor, connected home, connected media player and prosumer and industrial audio/video.  The consumer electronics market is highly competitive and is characterized by, among other things, frequent introductions of new products and short product life cycles.  The consumer electronics market may also be negatively impacted by a slowdown in overall consumer spending.  The worldwide economy, generally, and consumer spending, specifically, has significantly declined, which has negatively impacted our target markets.  If our target markets do not grow as rapidly or to the extent we anticipate, our business could suffer.  We expect the majority of our revenue for the foreseeable future to come from the sale of our SoC solutions for use in emerging consumer applications.  Our ability to sustain and increase revenue is in large part dependent on the continued growth of these rapidly evolving market sectors, whose future is largely uncertain.  Many factors could impede or interfere with the expansion of these consumer market sectors, including consumer demand in these sectors, general economic conditions, other competing consumer electronic products, delays in the deployment of telecommunications video services and insufficient interest in new technology innovations.  In addition, if market acceptance of the consumer products that utilize our products does not occur as expected, our business could be harmed.

We have a history of fluctuating operating results, including a net loss in fiscal 2006 and we may not be able to sustain or increase profitability in the future, which may cause the market price of our common stock to decline.

We have a history of fluctuating operating results.  We reported net income of $70.2 million in fiscal 2008, net income of $26.4 million in fiscal 2009, net income of $2.5 million in fiscal 2010 and net income of $9.1 million in fiscal 2011.  To sustain or increase profitability, we will need to successfully develop new products and product enhancements and sustain higher revenue while controlling our cost and expense levels.  In recent years, we made significant investments in our product development efforts and have expended substantial funds to enhance our sales and marketing efforts and otherwise operate our business.  However, we may not realize the benefits of these investments.  Although we were profitable in fiscal 2011, we may not continue to be profitable.  We may incur operating losses in future quarterly periods or fiscal years, which in turn could cause the price of our common stock to decline.

We have engaged, and may in the future engage in acquisitions of other businesses and technologies which could divert our attention and prove difficult to integrate with our existing business and technology.

We continue to consider investments in and acquisitions of other businesses, technologies or products, to improve our market position, broaden our technological capabilities and expand our product offerings.  For example, in November 2009, we completed the acquisition of CopperGate Communications Ltd., an Israeli company.  As a result, we added substantial operations, including 124 employees located in Israel and an additional 17 employees located outside of Israel.  We also completed the acquisition of Zensys Holdings Corporation in December 2008, the acquisition of certain assets and 44 new employees of the VXP Group from Gennum Corporation in February 2008 and the acquisition of Blue7 Communications in February 2006.  In the future, we may not be able to acquire or successfully identify companies, products or technologies that would enhance our business.  Once we identify a strategic opportunity, the process to consummate a transaction could divert our attention from the operation of our business causing our financial results to decline.

Acquisitions may require large one-time charges and can result in increased debt or contingent liabilities, adverse tax consequences, additional stock-based compensation expense, and the recording and subsequent amortization of amounts related to certain purchased intangible assets, any of which items could negatively impact our results of operations.  We may also record goodwill in connection with an acquisition and incur goodwill impairment charges in the future.  In addition, in order to complete acquisitions, we may issue equity securities and incur debt, which would result in dilution to our existing shareholders and could negatively impact profitability.

We may experience difficulties in integrating acquired businesses.  Integrating acquired businesses involves a number of risks, including:

• potential disruption of our ongoing business and the diversion of management resources from other business concerns;

• unexpected costs or incurring unknown liabilities;

22

• difficulties relating to integrating the operations and personnel of the acquired businesses;

• adverse effects on the existing customer relationships of acquired companies; and

• adverse effects associated with entering into markets and acquiring technologies in areas in which we have little experience.

If we are unable to successfully integrate the businesses we acquire, our operating results could be harmed.

The volatile global economy could negatively affect our business, results of operations and financial condition.

Current uncertainty in global economic conditions poses a risk to the overall economy as consumers and businesses may defer purchases in response to tighter credit and negative financial news, which could negatively affect demand for our products and other related matters.  Consequently, demand for our products could be different from our expectations due to factors including:

• changes in business and economic conditions, including conditions in the credit market that could negatively affect consumer confidence;

• customer acceptance of our products and those of our competitors;

• changes in customer order patterns including order cancellations; and

• reductions in the level of inventory our customers are willing to hold.

There could also be a number of secondary effects from the current uncertainty in global economic conditions, such as insolvency of suppliers resulting in product delays, an inability of our customers to obtain credit to finance purchases of our products or a desire of our customers to delay payment to us for the purchase of our products.  The effects, including those mentioned above, of the current global economic environment could negatively impact our business, results of operations and financial condition.

Due to the cyclical nature of the semiconductor industry, our operating results may fluctuate significantly, which could adversely affect the market price of our common stock.

The semiconductor industry is highly cyclical and subject to rapid change and evolving industry standards and, from time to time, has experienced significant downturns.  These downturns are characterized by decreases in product demand, excess customer inventories and accelerated erosion of prices.  These factors have caused, and could cause, substantial fluctuations in our net revenue and in our operating results.  Any downturns in the semiconductor industry may be severe and prolonged, and any failure of this industry to fully recover from downturns could harm our business.  The semiconductor industry also periodically experiences increased demand and production capacity constraints, which may affect our ability to ship products.  Accordingly, our operating results have varied and may vary significantly as a result of the general conditions in the semiconductor industry, which could cause our stock price to decline.

The complexity of our international operations may increase our operating expenses and disrupt our business.

We transact business and have operations worldwide.  For example, we derive a substantial portion of our net revenue from our customers outside of North America and we plan to continue expanding our business in international markets in the future.  For fiscal 2011, we derived 95% of our revenue from customers outside of North America.  We also have significant international operations, including operations in Israel, sales centers in Singapore and Taiwan, research and development facilities in Canada, France, Japan and Vietnam, a sales and research and development office in Denmark, and a sales and distribution facility in Hong Kong.

As a result of our international business, we are affected by economic, regulatory and political conditions in foreign countries, including the imposition of government controls, changes or limitations in trade protection laws, unfavorable changes in tax treaties or laws, varying statutory equity requirements, difficulties in collecting receivables and enforcing contracts, natural disasters, labor unrest, earnings expatriation restrictions, misappropriation of intellectual property, changes in import/export regulations, tariffs and freight rates, economic instability, public health crises, acts of terrorism and continued unrest in many regions and other factors, which could have a material impact on our international revenue and operations. In particular, in some countries we may experience reduced intellectual property protection.  Our results of operations could also be adversely affected by exchange rate fluctuations, which could increase the sales price in local currencies of our products in international markets.  Overseas sales and purchases to date have been denominated in U.S. dollars.  Although we engage in some hedging of our foreign currency exposures, we do not hedge all such exposures and our hedging arrangements may not always be effective.  See “Foreign currency exchange rate sensitivity” under Part II Item 7A“Quantitative and Qualitative Disclosures about Market Risk” in this Form 10-K.  Moreover, local laws and customs in many countries differ significantly from those in the United States.  We also face challenges in staffing and managing our global operations.  If we are unable to manage the complexity of our global operations successfully, our financial performance and operating results could suffer.

23

Our sales cycle can be lengthy, which could result in uncertainty and delays in generating net revenue.

Because our products are based on constantly evolving technologies, we have experienced a lengthy sales cycle for some of our SoCs, particularly those designed for set-top box applications in the IPTV media processor market.  After we have qualified a product with a customer, the customer will usually test and evaluate our product with its service provider prior to the customer completing the design of its own equipment that will incorporate our product.  Our customers and the telecommunications carriers our customers serve may need from three to more than nine months to test, evaluate and adopt our product and an additional three to more than nine months to begin volume production of equipment that incorporates our product.  Our complete sales cycle typically ranges from nine to eighteen months, but could be longer.  As a result, we may experience a significant delay between the time we increase expenditures for research and development, sales and marketing efforts and inventory and the time we generate net revenue, if any, from these expenditures.  In addition, because we do not have long-term commitments from our customers, we must repeat our sales process on a continual basis even for current customers looking to purchase a new product.  As a result, our business could be harmed if a customer reduces or delays its orders, chooses not to release products incorporating our SoCs or elects not to purchase a new product or product enhancements from us.

We rely on a limited number of independent third-party manufacturers for the fabrication, assembly and testing of our SoCs and the failure of any of these third-party manufacturers to deliver products or otherwise perform as requested could damage our relationships with our customers, decrease our sales and limit our growth.

We are a fabless semiconductor company and thus we do not own or operate a fabrication or manufacturing facility.  We depend on independent manufacturers, each of whom is a third-party manufacturer for numerous companies, to manufacture, assemble and test our products.  We currently rely on Taiwan Semiconductor Manufacturing Corporation, or TSMC, and, to a lesser extent, United Microelectronics Corporation, or UMC, to produce substantially all of our SoCs.  We rely on Advanced Semiconductor Engineering, Inc., or ASE, to assemble, package and test substantially all of our products.  These third-party manufacturers may allocate capacity to the production of other companies' products while reducing product deliveries or the provision of services to us on short notice or they may increase the prices of the products and services they provide to us with little or no notice.  In particular, other clients that are larger and better financed than we are or that have long-term agreements with ASE, TSMC or UMC may cause any or all of them to reallocate capacity to those clients, decreasing the capacity available to us.

If we fail to effectively manage our relationships with the third-party manufacturers, if we are unable to secure sufficient capacity at our third-party manufacturers' facilities or if any of them should experience delays, disruptions or technical or quality control problems in our manufacturing operations or if we had to change or add additional third-party manufacturers or contract manufacturing sites, our ability to ship products to our customers could be delayed, our relationships with our customers would suffer and our market share and operating results would suffer. If our third-party manufacturers' pricing for the products and services they provide increases and we are unable to pass along such increases to our customers, our operating results would be adversely affected.  Also, the addition of manufacturing locations or additional third-party subcontractors would increase the complexity of our supply chain management.  Moreover, all of our product manufacturing, assembly and packaging is performed in Asian countries and is therefore subject to risks associated with doing business in these countries such as quarantines or closures of manufacturing facilities due to the outbreak of viruses such as swine flu, SARS, avian flu or any similar outbreaks.  Each of these factors could harm our business and financial results.

We may not be able to effectively manage our growth or develop our financial and managerial control and reporting systems, and we may need to incur significant expenditures to address the additional operational and control requirements of our growth, either of which could harm our business and operating results.

To continue to grow, we must continue to expand and improve our operational, engineering, accounting and financial systems, procedures, controls and other internal management systems.  This may require substantial managerial and financial resources and our efforts in this regard may not be successful.  Our current systems, procedures and controls may not be adequate to support our future operations.  For example, we implemented a new enterprise resource management system in 2008.  We integrated the operations of CopperGate into our enterprise resource management system in the third quarter of fiscal 2011.  Any integration efforts could be costly and time consuming.  If we fail to adequately manage our growth or to improve and develop our operational, financial and management information systems or fail to effectively motivate or manage our current and future employees, the quality of our products and the management of our operations could suffer, which could adversely affect our operating results.

24

Our ability to develop, market and sell products could be harmed if we are unable to retain or hire key personnel.

Our future success depends upon our ability to recruit and retain the services of key executive, engineering, finance and accounting, sales, marketing and support personnel.  The supply of highly qualified individuals, in particular engineers in very specialized technical areas, or sales people specializing in the semiconductor industry, is limited and competition for such individuals is intense.  None of our officers or key employees is bound by an employment agreement for any specific term.  The loss of the services of any of our key employees, the inability to attract or retain key personnel in the future or delays in hiring required personnel, particularly engineers and sales people, and the complexity and time involved in hiring and training new employees, could delay the development and introduction of new products, and negatively impact our ability to market, sell or support our products.

If credit market conditions deteriorate further, it could have a material adverse impact on our investment portfolio.

U.S. sub-prime mortgage defaults have had a significant impact across various sectors of the financial markets, causing global credit and liquidity related difficulties.  Beginning mid 2007, global short-term funding markets have experienced credit issues, leading to liquidity issues and failed auctions in the auction rate securities market.  If the global credit market continues to be weak or deteriorates further, the liquidity of our investment portfolio may be impacted and we could determine that some of our investments are impaired.  This could materially adversely impact our results of operations and financial condition.

Litigation due to stock price volatility or other factors could cause us to incur substantial costs and divert our attention and resources.

In the past, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities.  Companies such as ours in the semiconductor industry and other technology industries are particularly vulnerable to this kind of litigation due to the high volatility of their stock prices.  While we are not aware of any such contemplated class action litigation against us, we may in the future be the target of securities litigation.  Any future lawsuits to which we may become a party will likely be expensive and time consuming to investigate, defend and resolve.  Such costs, which include investigation and defense, the diversion of our attention and resources and any losses resulting from these claims, could significantly increase our expenses and adversely affect our profitability and cash flow.

Our business may become subject to seasonality, which may cause our revenue to fluctuate.

Our business may become subject to seasonality as a result of our target markets.  We sell a significant number of our semiconductor products into the consumer electronics market.  Our customers who manufacture products for the consumer market typically experience seasonality in the sales of their products which in turn may affect the timing and volume of orders for our SoCs.  Although we have not experienced seasonality to date in sales of our products due to the overall growth in demand for our semiconductor products, we may, in the future, experience lower sales in our first fiscal quarter and higher sales in our second fiscal quarter as a result of the seasonality of demand associated with the consumer electronics markets into which we sell a portion of our products.  As a result, our operating results may vary significantly from quarter to quarter.

In the event we seek or are required to use a new manufacturer to fabricate or to assemble and test all or a portion of our SoC products, we may not be able to bring new manufacturers on-line rapidly enough, which could damage our relationships with our customers, decrease our sales and limit our growth.

We use a single wafer foundry to manufacture a substantial majority of our products and a single source to assemble and test substantially all of our products, which exposes us to a substantial risk of delay, increased costs and customer dissatisfaction in the event our third-party manufacturers are unable to provide us with our SoC requirements.  Particularly during times when semiconductor capacity is limited, we may seek to, and in the event that our current foundry were to stop producing wafers for us altogether, we would be required to, qualify one or more additional wafer foundries to meet our requirements, which would be time consuming and costly.  In order to bring any new foundries on-line, we and our customers would need to qualify their facilities which process could take as long as several months.  Once qualified, each new foundry would then require an additional number of months to actually begin producing SoCs to meet our needs, by which time our perceived need for additional capacity may have passed, or the opportunities we previously identified may have been lost to our competitors.  Similarly, qualifying a new provider of assembly, packaging and testing services would be a lengthy and costly process and, in both cases, they could prove to be less reliable than our existing manufacturers, which could result in increased costs and expenses as well as delays in deliveries of our products to our customers.

25

Our ability to raise capital in the future may be limited and our failure to raise capital when needed could prevent us from executing our growth strategy.

We believe that our existing cash and cash equivalents, and short-term and long-term marketable securities will be sufficient to meet our anticipated cash needs for at least the next 12 months.  The timing and amount of our working capital and capital expenditure requirements may vary significantly depending on numerous factors, including:

• market acceptance of our products;

• the need to adapt to changing technologies and technical requirements;

• the existence of opportunities for expansion; and

• access to and availability of sufficient management, technical, marketing and financial personnel.

If our capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity securities or debt securities or obtain debt financing.  During fiscal 2009, we used an aggregate of $85.9 million to purchase 4.2 million shares of our common stock.  In November 2009, we used approximately $116.0 million in cash (which includes approximately $28.0 million of acquired CopperGate cash) for the acquisition of CopperGate.  The amount of cash we used for these repurchases and the acquisition of CopperGate could limit our ability to execute our business plans and require us to raise additional capital in the future in order to fund any further repurchases or for other purposes.  The sale of additional equity securities or convertible debt securities would result in additional dilution to our shareholders.  Additional debt would result in increased expenses and could result in covenants that would restrict our operations.  We have not made arrangements to obtain additional financing and there is no assurance that financing, if required, will be available in amounts or on terms acceptable to us, if at all.

Regional instability in Israel may adversely affect business conditions and may disrupt our operations and negatively affect our revenues and profitability.

As a result of our acquisition of CopperGate in November 2009, we have engineering facilities, corporate and sales support operations and, as of January 29, 2011, we had 136 employees located in Israel.  Accordingly, political, economic and military conditions in Israel may directly affect our business.  Since the establishment of the State of Israel in 1948, a number of armed conflicts have taken place between Israel and its Arab neighbors, as well as incidents of civil unrest.  In addition, Israel and companies doing business with Israel have, in the past, been the subject of an economic boycott.  Although Israel has entered into various agreements with Egypt, Jordan and the Palestinian Authority, Israel has been and is subject to civil unrest and terrorist activity, with varying levels of severity since September 2000.  Any future armed conflicts or political instability in the region may negatively affect business conditions and adversely affect our results of operations.

In addition, our business insurance does not cover losses that may occur as a result of events associated with the security situation in the Middle East.  Although the Israeli government currently covers the reinstatement value of direct damages that are caused by terrorist attacks or acts of war, we cannot assure you that this government coverage will be maintained.  Any losses or damages incurred by us could have a material adverse effect on our business and financial results.

Changes in our effective tax rate or tax liability may have an adverse effect on our results of operations.

As a global company, we are subject to taxation in Israel, Singapore, the United States and various other countries and states.  Significant judgment is required to determine and estimate worldwide tax liabilities.  Any significant change in our future effective tax rates could adversely impact our consolidated financial position, results of operations and cash flows.  Our future effective tax rates may be adversely affected by a number of factors including:

• changes in tax laws in the countries in which we operate or the interpretation of such tax laws;

• changes in the valuation of our deferred tax assets;

• increases in expenses not deductible for tax purposes, including write-offs of acquired in-process research and development and impairment of goodwill in connection with acquisitions;

• changes in stock-based compensation expense;

26

• changes in generally accepted accounting principles; and

• our ability to use our tax attributes such as research and development tax credits and net operating losses of acquired companies to the fullest extent.

During fiscal 2009, we established a foreign operating subsidiary in Singapore.  We anticipate that a portion of our consolidated pre-tax income will continue to be subject to foreign tax at relatively lower tax rates when compared to the United States federal statutory tax rate and, as a consequence, our effective income tax rate has been and is expected to continue to be lower than the United States federal statutory rate.  Our future effective income tax rates could be adversely affected if tax authorities challenge our international tax structure or if the relative mix of United States and international income changes for any reason.  Accordingly, there can be no assurance that our income tax rate will be less than the United States federal statutory rate.

The income tax benefits in Israel to which we are currently entitled from our approved enterprise program may be reduced or eliminated by the Israeli government in the future and also require us to satisfy specified conditions.  If they are reduced or if we fail to satisfy these conditions, we may be required to pay increased taxes and would likely be denied these benefits in the future.

      The Investment Center of the Ministry of Industry, Trade and Labor has granted “approved enterprise” status to certain product development programs at our facility in Tel Aviv.  Our taxable income from these approved enterprise programs is exempt from tax for a period of two years from 2010 and will be subject to a reduced tax for an additional eight years thereafter, depending on the percentage of our share capital held by non-Israelis.  The Israeli government may reduce, or eliminate in the future, tax benefits available to approved enterprise programs.  Our approved program and the resulting tax benefits may not continue in the future at their current levels or at any level.  The termination or reduction of these tax benefits would likely increase our tax liability.  Additionally, the benefits available to an approved enterprise program are dependent upon the fulfillment of conditions stipulated under applicable law and in the certificate of approval.  If we fail to comply with these conditions, in whole or in part, or fail to get approval in whole or in part, we may be required to pay additional taxes for the period in which we benefited from the tax exemption or reduced tax rates and would likely be denied these benefits in the future.  In either case, the amount by which our taxes would increase will depend on the difference between the then applicable tax rate for non-approved enterprises and the rate of tax, if any, that we would otherwise pay as an approved enterprise, and the amount of any taxable income that we may earn in the future.  The current maximum enterprise tax rate in Israel is 25%.

 Failure to maintain effective internal controls over financial reporting may cause us to delay filing our periodic reports with the SEC, affect our NASDAQ listing and adversely affect our stock price.

The SEC, as directed by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules requiring public companies to include a report of management on internal control over financial reporting in their annual reports on Form 10-K. Our management is responsible for maintaining internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with GAAP. Our management assessed the effectiveness of our internal control over financial reporting as of January 29, 2011 and concluded that our internal control over financial reporting was effective.  Please see Item 9A. Controls and Procedures.  Although we review our internal control over financial reporting in order to ensure compliance with the Section 404 requirements, our failure to maintain adequate internal controls over financial reporting could result in an adverse reaction in the financial marketplace due to a loss of investor confidence in the reliability of our financial statements, which ultimately could negatively impact our stock price.

Our headquarters, certain of our other facilities, and some of our suppliers and third-party manufacturers are located in active earthquake zones.  Earthquakes, tsunamis or other types of natural disasters affecting us, our suppliers or manufacturers could cause resource shortages and production delays, which would disrupt and harm our business, results of operations and financial condition.

We are headquartered in the San Francisco Bay Area, have several research and development and sales offices in Japan and outsource most of our manufacturing to Taiwan.  Each of these areas is an active earthquake zone, and certain of our suppliers and third-party manufacturers conduct operations in the same regions or in other locations that are susceptible to natural disasters.  While we have not yet been impacted by the recent catastrophic earthquake and tsunami in Japan, any further devastation to this region could result in production delays or supply shortages.  The occurrence of a natural disaster, such as an earthquake, tsunami or flood, or localized extended outages of critical utilities or transportation systems, or any critical resource shortages, affecting us, our suppliers or our third-party manufacturers could cause a significant interruption in our production, business, damage or destroy our facilities or those of our suppliers and cause us to incur significant costs or result in limitations on the availability of our raw materials, any of which could harm our business, financial condition and results of operations.

27

Risks Related to Our Common Stock

Our operating results are subject to significant fluctuations due to many factors and any of these factors could adversely affect our stock price.

Our operating results have fluctuated in the past and may continue to fluctuate in the future due to a number of factors, including:

• the loss of one or more significant customers;

• changes in our pricing models and product sales mix;

• unexpected reductions in unit sales and average selling prices, particularly if they occur precipitously;

• new product introductions by us and our competitors;

• the level of acceptance of our products by our customers and acceptance of our customers' products by their end user customers;

• an interrupted or inadequate supply of semiconductor chips or other materials included in our products;

• availability of third-party manufacturing capacity for production of certain products;

• shifts in demand for the technology embodied in our products and those of our competitors;

• the timing of, and potential unexpected delays in, our customer orders and product shipments;

• the impairment and associated write-down of strategic investments that we may make from time-to-time;

• write-downs of accounts receivable;

• inventory obsolescence;

• a significant increase in our effective tax rate in any particular period as a result of the exhaustion, disallowance or accelerated recognition of our net operating loss carryforwards or otherwise;

• technical problems in the development, production ramp up and manufacturing of products, which could cause shipping delays;

• the impact of potential economic instability in the United States and Asia-Pacific region, including the continued effects of the recent worldwide economic slowdown;

• expenses related to implementing and maintaining a new enterprise resource management system and other information technologies; and

• expenses related to our compliance efforts with Section 404 of the Sarbanes-Oxley Act of 2002.

In addition, the market prices of securities of semiconductor and other technology companies have been volatile.  This volatility has significantly affected the market prices of securities of many technology companies for reasons frequently unrelated to the operating performance of the specific companies.

Accordingly, you may not be able to resell your shares of common stock at or above the price you paid.  

Our stock price has demonstrated volatility and continued volatility in the stock market may cause further fluctuations or decline in our stock price.

The market for our common stock has been subject to significant volatility which is expected to continue.  For example, the high and low selling prices per share of our common stock on the NASDAQ Global Market ranged from a high of $15.02 on January 18, 2011 to a low of $9.42 on July 7, 2010 during fiscal 2011.  During fiscal 2010, the high and low selling prices per share of our common stock on the NASDAQ Global Market ranged from a high of $17.63 on June 22, 2009 to a low of $9.59 on February 3, 2009.  This volatility is often unrelated or disproportionate to our operating performance.  These fluctuations, as well as general economic and market conditions, could cause the market price of our common stock to decline.

28

If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse opinion regarding our stock, our stock price and trading volume could decline.

The trading market for our common stock is influenced by the research and reports that industry or securities analysts publish about us or our business.  If one or more of the analysts who cover us issue an adverse opinion regarding our stock, our stock price would likely decline.  If one or more of these analysts cease coverage of Sigma or fail to regularly publish reports on us, we could lose visibility in the financial markets which in turn could cause our stock price or trading volume to decline.

Provisions in our organizational documents, our shareholders rights agreement and California law could delay or prevent a change in control of Sigma that our shareholders may consider favorable.

Our articles of incorporation and bylaws contain provisions that could limit the price that investors might be willing to pay in the future for shares of our common stock.  Our Board of Directors can authorize the issuance of preferred stock that can be created and issued by our Board of Directors without prior shareholder approval, commonly referred to as "blank check" preferred stock, with rights senior to those of our common stock.  The rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that we may issue in the future.  The issuance of preferred stock could have the effect of delaying, deterring or preventing a change in control and could adversely affect the voting power of your shares.  In addition, our Board of Directors has adopted a shareholder rights plan that provides each share of our common stock with an associated right to purchase from us one one-thousandth share of Series D participating preferred stock at a purchase price of $58.00 in cash, subject to adjustment in the manner set forth in the rights agreement.  The rights have anti-takeover effects in that they would cause substantial dilution to a person or group that attempts to acquire a significant interest in Sigma on terms not approved by our Board of Directors.  In addition, provisions of California law could make it more difficult for a third party to acquire a majority of our outstanding voting stock by discouraging a hostile bid or delaying or deterring a merger, acquisition or tender offer in which our shareholders could receive a premium for their shares or a proxy contest for control of Sigma or other changes in our management.

ITEM 1B.  UNRESOLVED STAFF COMMENTS

None.

ITEM 2.  PROPERTIES

We currently lease an approximately 66,000 square foot facility in Milpitas, California that is used as our headquarters.  The lease on this facility commenced on June 30, 2007 and will expire in September 2012.  We also lease an approximately 31,000 square foot facility in Tel-Aviv, Israel that is used for our Israel operation.  We have the right to renew the lease for the Israel facility until December 14, 2016.  We also lease facilities for sales offices in Singapore and Taiwan and a warehouse and sales office in Hong Kong.  Additionally, we lease facilities for research and development in Canada, France, Japan, Vietnam and San Diego, California and a facility for sales and research and development in Denmark.

ITEM 3.  LEGAL PROCEEDINGS

We are not currently a party to any material legal proceedings.  From time to time, we are involved in claims and legal proceedings that arise in the ordinary course of business.  We expect that the number and significance of these matters will increase as our business expands.  In particular, we could face an increasing number of patent and other intellectual property claims as the number of products and competitors in our industry grows.  Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of our time, result in the diversion of significant operational resources, or require us to enter into royalty or licensing agreements which, if required, may not be available on terms favorable to us or at all.  Were an unfavorable outcome to occur against us, there exists the possibility of a material adverse impact on our financial position and results of operations for the period in which the unfavorable outcome occurs, and potentially in future periods.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion in conjunction with our consolidated financial statements and related notes.  Except for historical information, the following discussion contains forward-looking statements within the meaning of Section 27A of the Securities Exchange Act of 1933 and Section 21E of the Securities Exchange Act of 1934.

Overview

We are a leading fabless provider of highly integrated system-on-chip, or SoC, solutions that are used to deliver multimedia entertainment throughout the home.  We offer four separate product lines: media processors, home networking products, video image processors and home control and energy management automation products.  Each of these product lines contributes to our fully integrated SoC offerings.  We sell our products into four primary target markets: the IPTV media processor, connected home, connected media player and prosumer and industrial audio/video markets.  We also sell a small amount of our products into other markets, such as the high definition television, or HDTV, and PC-based add-in markets, which we refer to as our other market.

IPTV Media Processor market:

The IPTV media processor market consists of consumer and commercial products, primarily set-top boxes, which receive and distribute streaming video and audio using IP.  We serve this market primarily with our media processor product line.  We believe we are the leading provider of high definition digital media processor SoCs for set-top boxes in the IPTV media processor market in terms of units shipped.  Our products are used by leading IPTV set-top box providers, such as Cisco Systems, Motorola, Netgem and Samsung.  IPTV set-top boxes incorporating our chipsets are deployed by telecommunications carriers globally including carriers in Asia, Europe and North America such as AT&T, Duetsche Telecom, NTT and SFR.  We work with these carriers and set-top box providers as well as with systems software providers, such as Microsoft and various Android and Linux providers, to design solutions that address the carriers' specific requirements regarding features and performance.  In connection with our efforts to expand our IPTV media processor market, we have development projects underway to address the hybrid set-top box opportunities that result from combining IPTV with cable and terrestrial broadcast reception.

Connected Home market:

The connected home market consists of communication devices that use a standard protocol to connect equipment inside the home and stream IP-based video and audio, voice over IP, or VoIP, or data through wired or wireless connectivity.  We target the connected home market with our wired and wireless home networking and home control and energy management automation products.  Our wired networking products use three technologies, HPNA, HPAV and G.hn.  Our HPNA products are currently used in IPTV set-top boxes as well as residential gateways, optical network terminals, multi-dwelling unit masters and network adapters by leading OEMs, such as Pace, Cisco Systems and Motorola.  Set-top boxes containing our products are deployed globally, primarily in North America, by telecommunications carriers such as AT&T, Bell Aliant, Bell Canada, Century Link and Telus.  Our wireless products use two technologies, Z-Wave and UWB.  Our wireless Z-Wave home control and energy management automation products are used in a wide variety of consumer products such as thermostats, light switches and door locks.  These consumer products are designed by leading industry participants such as Danfoss, Ingersoll-Rand (Schlage and Trane), Leviton and Cooper Wiring.  Our UWB products target high definition audio/video, or HDAV, speaker and home networking solutions over coaxial cables and wirelessly.  To date, we have not generated significant revenue from our products based on HPAV and UWB technologies and we have generated no revenue from our recently introduced products based on G.hn technology.

Connected Media Player market:

The connected media player market consists primarily of digital media adapters, or DMAs, portable media devices, wireless streaming PC or IP to TV devices and Blu-ray DVD players that perform playback of digital media stored in optical or hard disk formats.  We target this market with our media processor product line.  Our media processor SoCs are used by consumer electronics providers, such as Netgear, Sony and Western Digital in applications such as DMAs, Blu-ray DVD players, and other connected media player devices.

32

Prosumer and Industrial Audio/Video market:

The prosumer and industrial audio/video market consists of studio quality audio/video receivers and monitors, video conferencing, digital projectors and medical video monitors.  We target this market with our VXP video image processor product line.  Our VXP video image processor products are one of the leading solutions for studio-quality video image processing and are used by leading industry participants such as Harris, Panasonic, Polycom and Sony.

Our SoC Solutions

Our SoC solutions consist of highly integrated semiconductors and software that enables real-time processing of digital video and audio content, which we refer to as real-time software.  As a result, we believe our SoC solutions enable our customers to efficiently bring consumer multimedia devices to market.  We believe IPTV set-top box and connected media player designers and consumer device manufacturers select our SoC solutions because of the compelling nature of their performance and ease of integration.  Our highly integrated products have replaced a number of single function semiconductors with a multi-function SoC, which significantly improves performance and lowers power consumption and cost.

We sell our SoC solutions into each of our primary target markets.  For fiscal 2011 and 2010, we derived nearly 100% and 99%, respectively, of our net revenue from our SoC solutions. 

Characteristics of Our Business

We do not enter into long-term commitment contracts with our customers and generate substantially all of our net revenue based on customer purchase orders.  We forecast demand for our products based not only on our assessment of the requirements of our direct customers, but also on the anticipated requirements of the telecommunications carriers that our direct customers serve.  We work with both our direct customers and these carriers to address the market demands and the necessary specifications for our technologies.  However, our failure to accurately forecast demand can lead to product shortages that can impede production by our customers and harm our relationship with these customers or lead to excess inventory, which could negatively impact our gross margins in a particular period.

Many of our target markets are characterized by intense price competition.  The semiconductor industry is highly competitive and, as a result, we expect our average selling prices to decline over time.  On occasion, we have reduced our prices for individual customer volume orders as part of our strategy to obtain a competitive position in our target markets.  The willingness of customers to design our SoCs into their products depends to a significant extent upon our ability to sell our products at competitive prices.  If we are unable to reduce our costs sufficiently to offset any declines in product selling prices or are unable to introduce more advanced products with higher margins in a timely manner, we could see declines in our market share or gross margins.  We expect our gross margins will vary from period to period due to changes in our average selling prices and average costs, volume order discounts, mix of product sales, amount of development revenue and provisions for inventory obsolescence.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States, or US GAAP requires us to make judgments, assumptions and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes.  Note 1 to consolidated financial statements describes the significant accounting policies and methods used in the preparation of the consolidated financial statements.  We consider the accounting policies described below to be our critical accounting policies.  These critical accounting policies are impacted significantly by judgments, assumptions and estimates used in the preparation of the consolidated financial statements and actual results could differ materially from the amounts reported based on these policies.

Revenue recognition:  We derive our revenue primarily from three principal sources: product sales and, to a lesser extent, product development contracts and service contracts.  We recognize revenue for product sales and service contracts when persuasive evidence of an arrangement exists, delivery has occurred or service has been rendered, the fee is fixed or determinable and collectability is reasonably assured.

Revenue from product sales to OEMs, distributors and end users is recognized upon shipment when shipping terms are FOB shipping point, and revenue is deferred when we cannot reasonably estimate the amount of returns or where collectability is not assured.  When revenue is deferred, it is subsequently recognized when collection becomes probable and returns are estimable.  Allowances for sales returns, discounts and warranty costs are recorded at the time that the associated revenue is recognized.

Business Combinations:  We are required to allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed, as well as in-process research and development, or IPR&D, based on their estimated fair values.  Such valuations require us to make significant estimates and assumptions, especially with respect to intangible assets.  The significant purchased intangible assets recorded by us include customer relationships, developed technology, IPR&D and trademarks.

33

Critical estimates in valuing intangible assets include but are not limited to: future expected cash flows from acquired products, customer relationships and acquired developed technologies and patents; expected costs to develop IPR&D into commercially viable products and expected cash flows from completed projects; assumptions regarding brand awareness and market position, and assumptions about the period of time the brand will continue to be used in our product portfolio; and assumptions about discount rates. The estimated fair values are based upon assumptions that we believe to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates.

Valuation of Goodwill and Intangible Assets: We review goodwill and intangible assets with indefinite lives for impairment annually and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable.  An impairment charge is recorded if the carrying value exceeds the assets’ fair value.  Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives and are tested for impairment annually or if certain impairment indicators are identified.  We assess the carrying value of long-lived assets whenever events or changes in circumstances indicate that the carrying value of these assets is not recoverable.  Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions.  These estimates and assumptions include revenue growth rates and forecasted operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions and determination of appropriate market comparables.  We base our fair value estimates on assumptions we believe to be reasonable.  Actual future results may differ from those estimates.

Income taxes:Income taxes are accounted for under an asset and liability approach.  Deferred income taxes reflect the net tax effects of any temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts reported for income tax purposes, and any operating losses and tax credit carryforwards.  Deferred tax liabilities are recognized for future taxable amounts and deferred tax assets are recognized for future deductions, net of any valuation allowance, to reduce deferred tax assets to amounts that are considered more likely than not to be realized.

The impact of an uncertain income tax position on the income tax return must be recognized as the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority.  An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained.  Additionally, ASC 740, Income Taxes, provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. 

Valuation of inventories:  Inventories are stated at the lower of standard cost, which approximates actual cost on a first-in, first-out basis, or market value.  We evaluate our ending inventories for excess quantities and obsolescence on a quarterly basis.  This evaluation includes analysis of historical and forecasted unit sales by product.  A provision is recorded for inventories on hand in excess of forecasted demand.  In addition, we will write off inventories that are obsolete.  Obsolescence is determined from several factors, including competitiveness of product offerings, market conditions and product life cycles.  Increases to the allowance for excess and obsolete inventory are charged to cost of revenue.  At the time of the loss recognition, a new, lower-cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.  If this lower-cost inventory is subsequently sold, we will realize higher gross margins for those products.

Stock-based compensation:  We estimate the fair value of stock-based payment awards on the date of grant utilizing an option-pricing model, which is impacted by our common stock price as well as a change in assumptions regarding a number of highly complex and subjective variables.  These variables include, but are not limited to, our expected common stock price volatility over the term of the option awards, as well as the projected employee option exercise behaviors (expected period between stock option vesting date and stock option exercise date).  Option-pricing models have been developed for use in estimating the value of traded options that have no vesting or hedging restrictions and are fully transferable.  Employee stock options have certain characteristics that are significantly different from traded options, and changes in the subjective assumptions can materially affect the estimated fair value.  In our opinion, the existing Black-Scholes option-pricing model may not provide an accurate measure of the fair value of employee stock options.  Although the fair value of employee stock options is determined using an option-pricing model, the determined fair value may not be indicative of the fair value observed in a willing buyer/willing seller market transaction.  Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Valuation of marketable securities:  Our marketable securities primarily include certificates of deposit, corporate commercial paper, corporate bonds, money market funds and US agency discount notes.  Short-term marketable securities represent highly liquid debt instruments with a remaining maturity date at acquisition date of greater than 90 days but less than one year and are stated at fair value.  Long-term marketable securities represent securities with contractual maturities greater than one year from the date of acquisition.  Our marketable securities are classified as available-for-sale because the sale of such securities may be required prior to maturity.  The difference between amortized cost (cost adjusted for amortization of premiums and accretion of discounts, which is recognized as an adjustment to interest income) and fair value, representing unrealized holding gains or losses, are recorded separately as a component of accumulated other comprehensive income within shareholders’ equity.  Any gains and losses on the sale of marketable securities are determined on a specific identification basis.

34

We monitor all of our marketable securities for impairment and if these securities are reported to have a decline in fair value, use significant judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of each investment including: (i) the nature of the investment; (ii) the cause and duration of any impairment; (iii) the financial condition and future prospects of the issuer; (iv) for securities with a reported decline in fair value, our ability to hold the security for a period of time sufficient to allow for any anticipated recovery of fair value; (v) the extent to which fair value may differ from cost; and  (vi) a comparison of the income generated by the securities compared to alternative investments.  We recognize an impairment charge if a decline in the fair value of our marketable securities is judged to be other-than-temporary.

We previously held auction rate securities, or ARS.  ARS are bought and sold in the market place through a bidding process sometimes referred to as a “Dutch auction.”  Subsequent to February 2008, all auctions involving the ARS that we held failed.  In October 2008, we accepted an offer of a comprehensive settlement agreement from our cash investment advisor, UBS, in which all the ARS that we held could be redeemed at par value.  During the second quarter of fiscal 2011, all of the ARS that we held were redeemed at par value.

Accounts receivable:  We defer recognition of revenue and the related receivable when we cannot estimate whether collectability is reasonably assured at the time products and services are delivered to our customer.  We also provide allowances for bad debt and sales returns.  In establishing our allowance for bad debt, we review the customer's payment history and information regarding their credit worthiness.  In establishing our allowance for sales returns, we make estimates of potential future returns of products for which revenue has been recognized in the current period, including analyzing historical returns, current economic trends and changes in customer demand and acceptance of our products.  In fiscal 2011, 2010 and 2009, we recorded provisions for sales returns, discounts and bad debt in the total amounts of $0.3 million, $0.5 million and $0.9 million, respectively.  If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, or future product returns increased, additional allowances may be required.

Net revenue

Our net revenue for fiscal 2011 increased $80.8 million, or 39%, compared to fiscal 2010.  This increase in revenue for fiscal 2011 was primarily due to a 100% increase in units shipped partially offset by a 30% decrease in ASP across all product lines.  The increase in units shipped for fiscal 2011 was primarily the result of shipments of our home networking products, the majority of which we added to our product line in the fourth quarter of fiscal 2010, and increased shipments of our prosumer and industrial audio/video products, or VXP, due to increased orders from our existing customers in the VXP market.  The decline in ASP for fiscal 2011 was primarily the result of shipments of our home networking products which have lower ASPs than our media processor and VXP products.

35

Our net revenue for fiscal 2010 decreased $3.1 million, or 1%, compared to fiscal 2009.  This decrease in revenue for fiscal 2010 was primarily due to a 19% decline in the average selling price of our SoCs which was partially offset by a 21% increase in SoC units shipped.  The decline in average selling prices, or ASPs, and increase in shipments of SoCs, was primarily the result of shipments to our larger customers, who achieved cumulative volume pricing discounts on purchases of our products as well as shipments of our home networking products, the majority of which we added to our product line in the fourth quarter of fiscal 2010, and which have lower ASPs than our media processor and VXP products.

Net revenue by target market

We sell our products into four primary target markets, which are the IPTV media processor market, connected home market, the connected media player market and the prosumer and industrial audio/video market.  We also sell a small amount of our products into other markets, such as the high definition television, or HDTV, and PC-based add-in markets, which we refer to as our other market.

Our net revenue from sales into the connected home market increased in absolute dollars and as a percentage of total net revenue in fiscal 2011 primarily due to the addition of the product line we acquired through our acquisition of CopperGate in the fourth quarter of fiscal 2010.  The following table sets forth our net revenue by target market and the percentage of net revenue represented by our product sales to each target market (in thousands, except percentages):

	Fiscal Years Ended
	January 29,		% of		January 30,		% of		January 31,		% of

* The percentage of net revenue is less than one percent. 

IPTV media processor market:  For fiscal 2011, net revenue from sales of our SoC solutions, primarily our SMP8630 and SMP8650 SoC series, into the IPTV media processor market increased $2.4 million, or 2%, from fiscal 2010.  This increase was attributable to improved demand in our IPTV market that was partially offset by declining average selling prices due to certain customers achieving cumulative volume pricing discounts on purchases of our products.  Our revenue from the IPTV market as a percentage of our total net revenue decreased by 17% for fiscal 2011 compared to fiscal 2010 as a result of the increase in net revenue from the connected home market.

For fiscal 2010, net revenue from sales of our SoC solutions, primarily our SMP8630 SoC series, into the IPTV media processor market decreased $29.5 million, or 18%, from fiscal 2009.  This decline was attributable to weakness in demand as a result of the general economic downturn and declining average selling prices due to certain customers achieving cumulative volume pricing discounts on purchases of our products.  Our revenue from the IPTV media processor market as a percentage of our total net revenue decreased by 14% for fiscal 2010 compared to fiscal 2009 as a result of these factors and also due to the increase in net revenue for our connected media player and connected home markets.

Connected home market:  Prior to the second quarter of fiscal 2010, we referred to the connected home market as the wireless target market.  We believe the connected home market that we currently address with our home networking and home control and energy management automation product lines more accurately describes our target market.  For fiscal 2011, net revenue from sales of our products into the connected home market increased $76.3 million, or 412%, from fiscal 2010.  This increase was primarily the result of our acquisition of CopperGate in the fourth quarter of fiscal 2010.  For the same reason, our percentage of net revenue from sales into the connected home market increased by 24% as a percentage of our total net revenue for fiscal 2011.  We expect revenue from our connected home market to fluctuate in future periods based on changes in ASP and inventory levels at contract manufacturers who manufacture equipment incorporating our products for deployment by telecommunication providers, and competitive market pressures.

36

For fiscal 2010, net revenue from sales of our products into our connected home market increased $17.6 million compared to fiscal 2009.  This increase was the result of our acquisition of CopperGate in the fourth quarter of fiscal 2010 and Zensys Holdings Corporation in December 2008.  For the same reason, our percentage of net revenue from sales into the connected home market increased to 9% in fiscal 2010 as a percentage of our total net revenue compared to a minimal percentage in fiscal 2009.  

Connected media player market:  For fiscal 2011, net revenue from sales of our products to the connected media playermarket decreased $5.0 million, or 11%, from fiscal 2010.  This decrease was primarily attributable to a decrease in ASP for sales of our SoCs to customers who incorporate our SoCs into digital media adapters as these customers achieved cumulative volume pricing discounts on purchases of our products.  Our revenue from the connected media player market as a percentage of our total net revenue for fiscal 2011 compared to fiscal 2010 decreased by 8%, primarily as a result of the increase in revenue from our connected home market.

For fiscal 2010, net revenue from sales of our products to the connected media playermarket increased $14.6 million, or 48%, from fiscal 2009.  The increase was primarily attributable to increased unit sales of our SoCs to customers who incorporate our SoCs into digital media adapters.  For the same reason, our revenue from the connected media player market as a percentage of our total net revenue for fiscal 2010 increased 8% compared to fiscal 2009.

Prosumer and industrial audio/video market:  For fiscal 2011, net revenue from sales of our products into the prosumer and industrial audio/video market increased $7.8 million, or 108%, from fiscal 2010.  The increase was attributable to an increase in units shipped primarily due to strengthening demand from our existing customers and our continued effort to expand into this market.  Our revenue from sales into the prosumer and industrial audio/video market as a percentage of total net revenue increased by 1% for fiscal 2011 compared to fiscal 2010.

For fiscal 2010, net revenue from sales of our products into the prosumer and industrial audio/video market decreased $0.9 million, or 11%, from fiscal 2009.  The decline was attributable to an overall slowdown in the prosumer and industrial audio/video market as a result of the global economic downturn.  Our revenue from sales into the prosumer and industrial audio/video market as a percentage of total net revenue was unchanged for fiscal 2010 compared to fiscal 2009.

Other markets:  Our other markets consist of HDTV, PC add-in boards, development contracts, services and other ancillary markets.  For fiscal 2011, net revenue decreased $0.7 million, or 78%, compared to fiscal 2010.  The decrease was primarily due to lower engineering development fees for customization of our SoCs and a decline in sales of our SoCs to customers who incorporate our products into HDTVs.  For fiscal 2010, net revenue from this market decreased $4.9 million, or 85%, compared to fiscal 2009.  The decrease was primarily due to lower engineering development fees for customization of our SoCs and a decline in sales of our SoCs to customers who incorporate our products into HDTVs.

Net revenue by product group

Our primary product group consists of our SoC solutions.  To a lesser extent, we derive net revenue from other products and services.  The following table sets forth net revenue in each of our product groups and the percentage of net revenue represented by each product group (in thousands, except percentages):

	Fiscal Years Ended
	January 29,		% of Net		January 30,		% of Net		January 31,		% of Net
	2011		revenue		2010		revenue		2009		revenue

Net revenue	$	286,915		100%	$	206,083		100%	$	209,160		100%

*     The percentage of net revenue is less than one percent.

SoCs:  Our SoCs are targeted toward manufacturers and large volume designer and manufacturer customers building products for the IPTV media processor, connected home, connected media player and prosumer and industrial audio/video markets.  The increase of $80.9 million, or 40%, in fiscal 2011 compared to fiscal 2010 was due primarily to a 100% increase in units shipped partially offset by a 30% decrease in ASP.  Both the increase in units shipped and the decline in ASP for fiscal 2011 were primarily the result of shipments of home networking products which we added to our product line in the fourth quarters of fiscal 2010 as a result of the CopperGate acquisition and which have lower ASPs than our media processor and VXP products.

The decrease of $2.5 million, or 1%, in net revenue from SoCs for fiscal 2010 compared to fiscal 2009 was due primarily to a 19% decline in ASP of our SoCs which was partially offset by a 21% increase in SoC units shipped.  The decline in ASP was primarily the result of shipments of our home networking products which we added to our product line in the fourth quarter of fiscal 2010 as a result of the CopperGate acquisition and which have lower ASPs than our media processor and VXP products and the result of shipments of our media processor products to customers, who achieved cumulative volume pricing discounts.  The increase in SoC units shipped was primarily due to a higher volume of units shipped for our home networking and home control and energy management automation products as a result of our CopperGate and Zensys acquisitions and, to a lesser extent, our connected media player products.

37

Other:We derive revenue from other products and services, including software development kits, engineering support services for hardware and software, engineering development for customization of SoCs and other accessories.  The revenue derived from other products and services was not a significant portion of our total net revenue.  

Net revenue by geographic region

Prior to the first quarter of fiscal 2011, we reported our net revenue by geographic region based on billing location.  We believe reporting based on ship-to location provides more relevant information about our customer base.  Our net revenue by geographic region for the comparative periods has been reclassified based on the ship-to location of our customers.  The following table sets forth net revenue for each geographic region based on the ship-to location of customers (in thousands, except percentages):

	Fiscal Years Ended
	January 29,		% of		January 30,		% of		January 31,		% of
	2011		Net revenue		2010		Net revenue		2009		Net revenue

*     The percentage of net revenue is less than one percent.

Asia:  Our net revenue in absolute dollars from Asia increased $81.9 million, or 44%, for fiscal 2011 compared to fiscal 2010.  Our net revenue from Asia increased 4% as a percentage of our total net revenue for fiscal 2011 compared to fiscal 2010.  The increases in net revenue from Asia in both absolute dollars and as a percentage of our total net revenue were primarily attributable to an increase in revenue from China which resulted primarily from the increase in shipments of our home connectivity products as a result of our CopperGate acquisition in the fourth quarter of fiscal 2010.

As a percentage of total net revenue by country in the Asia region, China, including Hong Kong, represented 81% in fiscal 2011 and 82% in fiscal 2010.

Our net revenue in absolute dollars from Asia increased $24.5 million, or 15%, in fiscal 2010 compared to fiscal 2009.  Our net revenue from Asia increased 13% as a percentage of our total net revenue for fiscal 2010 compared to fiscal 2009.  The increase in net revenue from Asia in both absolute dollars and as a percentage of our total net revenue was primarily attributable to an increase in revenue from customers in Taiwan and China which was primarily attributable to customers shifting their production orders from contract manufacturers located in Europe to contract manufacturers in those countries.  In addition, in fiscal 2010, net revenue from Taiwan increased due to a customer ramping production of their DMA product.  This increase in both absolute dollars and as a percentage of our total net revenue was partially offset by a decline in the ASPs of our SoCs.

The following table sets forth the percentage of net revenue from countries in the Asia region that accounted for over 10% of net revenue:

	Fiscal Years Ended
	January 29,	January 30,	January 31,
	2011	2010	2009
China, including Hong Kong	81%	82%	68%

North America:  Our net revenue in absolute dollars from North America increased $7.4 million, or 123%, for fiscal 2011 compared to fiscal 2010.  Our net revenue from North America increased 2% as a percentage of our net revenue for fiscal 2011 compared to fiscal 2010.  The increases in our net revenue from North America in both absolute dollars and as a percentage of our net revenue were primarily attributable to increased demand in North America for our SoC solutions for our Z-Wave and VXP products.

Our net revenue in absolute dollars from North America decreased $19.0 million, or 76%, for fiscal 2010 compared to fiscal 2009.  Net revenue from North America decreased 9% as a percentage of total net revenue for fiscal 2010 compared to fiscal 2009.  The decrease in our net revenue from North America in both absolute dollars and as a percentage of our net revenue was primarily attributable to customers who incorporate our products into their finished goods placing their orders through contract manufacturers located outside of North America.

38

For fiscal 2011, our net revenue generated outside North America was 95% of our net revenue, compared to 97% in fiscal 2010 and 88% in fiscal 2009.  The overall trend has been for companies located in North America who incorporate our products into their finished products to move their production orders to large designers and manufacturers located in the Asia region.  We expect our revenue from North America in any given year to fluctuate depending on whether our customers place their orders locally or through overseas manufacturers who incorporate our products into their finished products.

Europe:  Our net revenue in absolute dollars from Europe decreased $8.8 million, or 55%, for fiscal 2011 compared to fiscal 2010.  The majority of the decrease in our net revenue from Europe in both absolute dollars and as a percentage of our total net revenue was attributable to certain European customers moving their production to Asia and, to lesser extent, a decline in demand for our products from a customer located in Europe.  Our net revenue from Europe decreased 6% as a percentage of our total net revenue for fiscal 2011 compared to fiscal 2010.  The decrease in our net revenue from Europe as a percentage of our total net revenue was primarily attributable to an increase in revenue from Asia which resulted primarily from the increase in shipments of our home connectivity products as a result of our CopperGate acquisition in the fourth quarter of fiscal 2010.

Our net revenue in absolute dollars from Europe for fiscal 2010 decreased $8.6 million, or 35%, compared to fiscal 2009.  Our net revenue from Europe decreased 4% as a percentage of our total net revenue for fiscal 2010 compared to fiscal 2009.  The decrease in our net revenue from Europe in both absolute dollars and as a percentage of our total net revenue was primarily attributable to an IPTV media processor customer who incorporates our products into their finished goods moving their production orders to contract manufacturers located in Asia starting in the third quarter of fiscal 2009, a decrease in demand for our IPTV media processor customers as a result of the general economic downturn and the impact of declining average selling prices due to certain customers achieving cumulative volume pricing discounts on purchases of our products.

We expect our net revenue from Europe in any given period to fluctuate depending on whether our customers place their orders locally or through their overseas manufacturers who incorporate our SoCs into their final products.

No individual country in Europe accounted for 10% or more of our net revenue in fiscal 2011, fiscal 2010 or fiscal 2009.

Major Customers

The following table sets forth the major direct customers that accounted for 10% or more of our net revenue:

	Fiscal Years Ended
	January 29,		January 30,		January 31,

Gross profit and Gross margin

The following table sets forth gross profit and gross margin (in thousands, except percentages):

	Fiscal Years Ended
	January 29,		%		January 30,		%		January 31,
	2011		change		2010		change		2009
Gross profit	$	140,644		53%		91,702		-9%	$	100,554
Gross margin		49%				44%				48%

Our gross profit increased $48.9 million, and gross margin increased 5 percentage points for fiscal 2011, compared to fiscal 2010.  These increases were due primarily to a 40% decline in our average cost per SoC during fiscal 2011 which were partially offset by a 30% decline in our ASP per SoC.  The decline in our average cost per SoC was primarily due to the increase in units shipped for our home connectivity products, which have a lower average cost than our media processor and VXP products, and a $4.8 million reduction in the mark-up on inventories purchased through our acquisitions of CopperGate and Zensys as the majority of the inventory was sold during fiscal 2010.  The improvement in our average cost per SoC was partially offset by an increase in our operations overhead costs of $6.1 million for fiscal 2011 compared to fiscal 2010 due to a $5.7 million increase in amortization of acquired intangibles primarily as a result of our acquisition of CopperGate in the fourth quarter of fiscal 2010.  The decline in ASP was primarily due to the addition of our home connectivity product line which has a lower ASP than our media processor product line.  

39

Our gross profit decreased $8.9 million, and gross margin decreased 4 percentage points for fiscal 2010 compared to fiscal 2009.  These decreases were due primarily to a 19% decline in our ASP per SoC which was partially offset by a 15% decline in our average cost per SoC unit.  The decline in ASP was primarily the result of shipments of our home networking products, which we added to our product line in the fourth quarter of fiscal 2010 as a result of the CopperGate acquisition and which have lower ASPs than our media processor and VXP products, and the result of shipments of our media processor products to customers, who achieved cumulative volume pricing discounts.  The decline in our average cost per SoC was primarily due to overall cost reductions from our suppliers as well as improved yields on our highest volume products.  This decline in our average cost per SoC was partially offset by operations overhead increasing by $2.8 million, or 50%, for fiscal 2010 compared to fiscal 2009.  This increase was primarily due to a $2.3 million increase in amortization of acquired intangibles and a $0.4 million increase in compensation and benefits costs due to our acquisitions of CopperGate and Zensys in the fourth quarters of fiscal 2010 and fiscal 2009, respectively.  Additionally, our gross margin in fiscal 2010 was lower compared to fiscal 2009 due to an increase of $3.2 million in connection with mark-up on inventories purchased through our acquisitions of CopperGate and Zensys.

Provisions for excess and obsolete inventory included in cost of revenue were $0.5 million in fiscal 2011, $0.3 million in fiscal 2010 and $2.1 million in fiscal 2009.

*           The percentage of net revenue is less than one percent.

For fiscal 2011 compared to fiscal 2010, compensation and benefits and stock-based compensation increased primarily due to an overall increase in headcount, including personnel added through our acquisition of CopperGate in November 2009.  The increase in depreciation and amortization was primarily due to amortization of acquired intangibles associated with the CopperGate acquisition.  Trade shows, travel and entertainment expenses increased as a result of our increased participation in trade shows primarily as a result of our added product lines.  External commissions fluctuated due to changes in net revenues for products sold through external sales representatives.  Other expenses increased primarily due to our additional facility in Israel as a result of our acquisition of CopperGate.

For fiscal 2010 compared to fiscal 2009, compensation and benefits increased primarily due to an overall increase in headcount, including personnel added through our acquisition of CopperGate in November 2009.  Depreciation and amortization increased primarily due to amortization of acquired intangibles associated with the CopperGate acquisition.  Trade shows, travel and entertainment expenses increased as a result of our increased participation in trade shows primarily as a result of our added product lines.  Stock-based compensation decreased due to a charge in fiscal 2009 for the acceleration of an option during that period.

General and administrative expense

General and administrative expense consists primarily of compensation and benefits costs, stock-based compensation expense, legal, accounting and other professional fees and facilities expenses.

The following tables set forth details of general and administrative expense for fiscal 2011, 2010 and 2009 (in thousands, except percentages):

For fiscal 2011 compared to fiscal 2010, compensation and benefits and stock-based compensation increased primarily due to an overall increase in headcount, primarily for personnel added through our acquisition of CopperGate in November 2009.  The decreases in legal and accounting fees and outside services are primarily due to legal and consulting fees related to the acquisition of CopperGate during fiscal 2010.  Other expenses increased primarily due to our additional facility in Israel as a result of our acquisition of CopperGate.

For fiscal 2010 compared to fiscal 2009, compensation and benefits increased due to an overall increase in headcount including personnel added through our acquisition of CopperGate in November 2009.  Outside services and legal and accounting fees increased primarily due to consulting and legal fees related to the acquisition of CopperGate.  Stock-based compensation decreased primarily due to a specific option cancelation during fiscal 2010 that significantly reduced our stock-based compensation expense in fiscal 2010.  Other expenses increased primarily as a result of increased facilities, depreciation and other costs as a result of our acquisition of CopperGate.

Acquired in-process research and development

Acquired in-process research and development, or IPR&D, expenses were zero in both fiscal 2011 and fiscal 2010.  IPR&D totaled $1.6 million in fiscal 2009 as a result of the VXP Group acquisition completed in February 2008.  The amount of the purchase price allocated to IPR&D was determined through established valuation techniques used in the high technology industry and was expensed upon acquisition as it was determined that the underlying projects had not reached technological feasibility and no alternative future use existed.

Stock-based compensation expense

The expensing of employee stock option grants will continue to have an adverse impact on our results of operations.  As of January 29, 2011, the unrecorded stock-based compensation balance related to stock options outstanding excluding estimated forfeitures was $30.9 million which will be recognized over an estimated weighted average amortization period of 3.4 years.  The amortization period is based on the expected vesting term of the options.  The increase in stock-based compensation expense for fiscal 2011 compared to fiscal 2010 was primarily due to an overall increase in headcount, including personnel added by our acquisition of CopperGate in November 2009.  The decrease in stock-based compensation expense for fiscal 2010 compared to fiscal 2009 was primarily due to the charge of $2.4 million during the first quarter of fiscal 2009 for an option granted and fully vested during that period and a $1.1 million reduction due to a specific option cancellation recorded in the first quarter of fiscal 2010.  Future stock-based compensation expense and unearned stock-based compensation will increase to the extent that we grant additional equity awards to employees or assume unvested equity awards in connection with any acquisitions.

Amortization of intangible assets

We classify our amortization expense for acquired developed technology of $10.3 million, $4.6 million and $2.3 million for fiscal 2011, 2010 and 2009, respectively, as cost of revenue.  We classify our amortization expense for acquired customer relationships and trademarks of $8.0 million, $2.1 million and $0.1 million for fiscal 2011, 2010 and 2009, respectively, as sales and marketing expense.  We classify our amortization expense for acquired noncompete agreements of zero, $19,000 and $0.5 million for fiscal 2011, 2010 and 2009, respectively, as research and development expense.  At January 29, 2011, the unamortized balance from purchased intangible assets was $107.6 million which we intend to amortize in future periods based on the remaining estimated useful lives of each acquired intangible asset.  If we purchase additional intangible assets in the future, our cost of revenue or other operating expenses may increase from the amortization of those assets.

Acquired intangible assets subject to amortization were as follows as of January 29, 2011 (in thousands, except for years):

	Gross Value		Accumulated Amortization		Net Value		Weighted average remaining amortization period (years)
Developed technology	$	72,910	$	18,770	$	54,140	5.7
Customer relationships		50,423		9,146		41,277	6.0
Trademarks		2,677		1,166		1,511	5.4
Noncompete agreements		1,400		1,400		—	—

In-process research and development		10,700		—		10,700
	$	138,110	$	30,482	$	107,628

We acquired IPR&D of $10.7 million in connection with our acquisition of CopperGate.  The fair value of the IPR&D was determined through estimates and valuation techniques based on the terms and details of the acquisition.  This IPR&D project is the development of our G.hn technology which we expect to result in our next generation home connectivity product that will provide increased data rates, ease of use and quality of service and backward compatibility to our current HomePNA and HomePlug AV products.  We expect to complete development on this project in the second half of fiscal 2012.  Upon completion of development, we will determine and begin amortization of the acquired IPR&D over its useful life.

Interest and other income, net

The following table sets forth our net interest and other income and related percentage change over the previous fiscal year for fiscal 2011, 2010 and 2009 (in thousands, except percentages):

	Fiscal Years Ended
	January 29,		%		January 30,		%		January 31,
	2011		change		2010		change		2009
Interest and other income, net	$	2,183		15%	$	1,906		-67%	$	5,698

Our other income and expense primarily consisted of interest income from marketable securities, income from refundable research and development credits, gain or loss on foreign exchange transactions and gain or loss realized on sales of marketable securities.  The increase of $0.3 million, or 15%, in fiscal 2011 compared to fiscal 2010 was primarily due to foreign exchange gains.  The decrease of $3.8 million, or 67%, in fiscal 2010 compared to fiscal 2009 was due primarily to a decrease in interest rates earned on our marketable securities portfolio.  Our foreign exchange exposure, primarily in the Canadian dollar, Danish krone, Euro and Israeli shekel, has increased compared to fiscal 2009 as a result of our further expansion into international locations and significant volatility of the U.S. dollar in relation to those currencies.  

Impairment of investment

During our second quarter of fiscal 2011, we recorded an impairment charge of $5.2 million against strategic investments we made in a privately held, venture capital funded technology company.  This impairment charge represents $2.0 million to fully write down the carrying value of our preferred stock investment and $3.2 million to fully reserve the convertible note and accrued interest receivable from this company due to our expected inability to collect it.  There was no impairment of investments in either fiscal 2010 or fiscal 2009.

44

Provision for income taxes

We recorded provisions for income taxes of $0.8 million, $2.7 million and $4.9 million in fiscal 2011, 2010 and 2009, respectively.  The fiscal 2011, 2010 and 2009 effective tax rates were approximately 8%, 52% and 16%, respectively.  Our fiscal 2011 effective tax rate differs from the federal statutory rate of 35% primarily due to the foreign tax differential resulting from the nature of our international operations of $3.5 million and the federal research and development tax credits of $1.2 million that became available during the last quarter of the fiscal year.  Our fiscal 2010 effective tax rate differs from the federal statutory rate of 35% primarily due to our international operations, which resulted in a foreign tax differential benefit of $3.0 million and the offsetting effect of $3.8 million from writing off the California deferred tax assets due to our assessment that it is not more likely than not to be realized in the future.  Our fiscal 2009 effective tax rate differs from the federal statutory rate of 35% primarily due to the nature of our international operations which resulted in a foreign tax differential benefit of $7.2 million.  

Liquidity and Capital Resources

The following table sets forth the cash and cash equivalents and short-term marketable securities as of January 29, 2011 and January 30, 2010 (in thousands):

	January 29,		January 30,
	2011		2010
Cash and cash equivalents	$	72,732	$	81,947
Short-term marketable securities		47,482		51,176
	$	120,214	$	133,123

As of January 29, 2011, our principal sources of liquidity consisted of cash and cash equivalents and short-term marketable securities of $120.2 million, which represents a decrease of $12.9 million from $133.1 million at January 30, 2010.  The decrease in cash and cash equivalents and short-term marketable securities was primarily the result of $44.0 million of net purchases of long-term marketable securities, $14.7 million in purchases of software, equipment and leasehold improvements and $2.3 million of long-term investments.  These outflows of cash, cash equivalents and short-term marketable securities were partially offset by $40.7 million of cash generated from our operating activities and $5.2 million in net proceeds from the sale of our common stock through our stock option plans and employee stock purchase plan.

Additionally, as of January 29, 2011 we held $57.3 million of long-term marketable securities.  Although these marketable securities have maturities of greater than one year, we hold them as available-for-sale and may access these funds prior to their contractual maturities.

We previously held auction rate securities, or ARS.  ARS are bought and sold in the market place through a bidding process sometimes referred to as a “Dutch auction.”  Subsequent to February 2008, all auctions involving the ARS that we held failed.  In October 2008, we accepted an offer of a comprehensive settlement agreement from our cash investment advisor, UBS, in which all the ARS that we held could be redeemed at par value.  During the second quarter of fiscal 2011, all of the ARS that we held were redeemed at par value.

The following table sets forth the primary net cash inflows and outflows for the fiscal 2011, 2010 and 2009 (in thousands):

Cash flows from operating activities

Net cash provided by operating activities of $40.7 million for fiscal 2011 was primarily due to net income of $9.1 million, non-cash expenses of $42.6 million which includes an investment impairment charge of $5.2 million, a $4.7 million increase in accounts payable, a $4.5 million decrease in accounts receivable, and a $1.6 million increase in accrued liabilities and other long-term liabilities.  These amounts were partially offset by a $20.0 million increase in inventories and a $1.8 million increase in prepaid expenses and other current assets and other non-current assets.  Non-cash adjustments included in net income in fiscal 2011 consisted primarily of $27.7 million for depreciation and amortization, $12.6 million for stock-based compensation expense and a benefit of $3.9 million for deferred income taxes.

The increase in inventories was the result of an increase in our die bank and finished goods as a result of an easing in supply of wafers and an increase in our die bank for our newer generation products to meet forecasted demand.  Despite the increase in inventories, our  annualized rate of inventory turns increased to 5.2 times per year for fiscal 2011 compared to 4.2 times per year for fiscal 2010 as a result of the overall increase in shipments in fiscal 2011.  The increase in accounts payable was primarily due to the timing of payment for inventories.  The decrease in accounts receivable was primarily the result of decreased product shipments and timing of billings in the fourth quarter of fiscal 2011 compared to the fourth quarter of fiscal 2010.  Our annual average days sales outstanding increased to 45 days at January 29, 2011 compared to 44 days at January 30, 2010, primarily due to timing of shipments and customer mix.

Net cash provided by operating activities of $51.9 million for fiscal 2010 was primarily due to net income of $2.5 million, non-cash expenses of $21.9 million, a $27.1 million decrease in inventories, a $1.2 million decrease in prepaid expenses and other assets and a $3.0 million increase in accounts payable.  These amounts were partially offset by a $3.2 million increase in accounts receivable and a $0.6 million decrease in accrued and other liabilities.  Non-cash expenses included in net income in fiscal 2010 consisted primarily of $13.2 million in depreciation and amortization and $8.8 million in stock-based compensation expense.  The decrease in inventories was the result of successful efforts to reduce the level of our die bank and a significant increase in demand in the fourth fiscal quarter of 2010 which resulted in an increase in our annualized rate of inventory turns to 4.2 for fiscal 2010 compared to 3.5 for fiscal 2009.  The increase in accounts payable was primarily due to the timing of payment for inventories.  The increase in accounts receivable was primarily the result of increased billings due to increased product shipments during the fourth quarter of fiscal 2010 compared to the fourth quarter of fiscal 2009.  Our annual average days sales outstanding improved to 44 days at January 30, 2010 compared to 57 days at January 31, 2009, primarily due to timing of shipments and customer mix.

Net cash provided by operating activities was $42.8 million for fiscal 2009.  The cash provided by our operating activities for fiscal 2009 was primarily due to net income of $26.4 million, non-cash operating expenses of $24.9 million, a $10.1 million decrease in accounts receivable, a $4.6 million increase in other long-term liabilities and a $0.4 million decrease in other assets.  These increases were partially offset by an $18.0 million decrease in accounts payable and accrued liabilities and a $5.5 million increase in inventories.  The decrease in accounts payable and accrued liabilities was primarily due to the timing of payments for tax liabilities and software licenses during the fourth quarter of fiscal 2009.  The decrease in accounts receivable was primarily due to lower product revenues in the fourth quarter of fiscal 2009.  The increase in inventories resulted from an increase in our die bank level at the end of the fiscal 2009.  At the end of fiscal 2009, our die bank was somewhat elevated relative to our sales volume due to a strategic build up of certain wafers for some of our key customers.  The increase in other long-term liabilities is primarily due to higher deferred tax obligations which resulted in increased long-term income taxes payable and deferred tax liabilities.  Non-cash charges included stock-based compensation of $12.7 million, depreciation and amortization of $7.2 million, provision for sales returns, discounts and doubtful accounts of $0.9 million, provisions for excess and obsolete inventory of $2.1 million and acquired in-process research and development of $1.6 million in fiscal 2009.

Cash flows from our operating activities will continue to fluctuate based upon our ability to grow net revenues while managing the timing of payments to us from customers and to vendors from us, the timing of inventory purchases and subsequent manufacture and sale of our products.

Cash flows from investing activities

Net cash used in investing activities was $57.3 million for fiscal 2011 which was primarily due to net purchases of marketable securities of $40.2 million, purchases of software, equipment and leasehold improvements of $14.7 million and purchases of long-term investments of $2.3 million.

Net cash used in investing activities was $64.6 million for fiscal 2010 which was primarily due to net cash paid of $89.1 million in connection with the acquisition of CopperGate, purchases of software, equipment and leasehold improvements of $7.5 million, an investment of $3.0 million in a convertible note receivable of a privately-held technology company, $1.5 million of private equity investments and $0.5 million of cash restricted for our foreign exchange hedging transactions.  These usages of cash in investing activities were partially offset by net sales and maturities of long-term marketable securities of $37.0 million.

46

Net cash used in our investing activities was $46.8 million for fiscal 2009, which was primarily due to net cash paid of $28.5 million in connection with the acquisitions of VXP and Zensys, purchases of software, equipment and leasehold improvements of $15.7 million and private equity investments of $3.0 million.

Cash flows from financing activities

Net cash provided by financing activities was $7.6 million in fiscal 2011 which was due to $5.2 million of proceeds from exercises of employee stock options and employee stock purchases and $2.3 million of excess tax benefit from stock-based compensation.

Net cash provided by financing activities was $3.4 million in fiscal 2010 which was due to $2.8 million of proceeds from exercises of employee stock options and employee stock purchases and $0.6 million of excess tax benefit from stock-based compensation.

Net cash used in financing activities was $78.9 million in fiscal 2009, which was the result of $85.9 million for the repurchase of 4.2 million shares of our common stock, partially offset by $4.6 million of proceeds from the exercise of employee stock options and employee stock purchases and $2.4 million of excess tax benefit from stock-based compensation.

While we generated cash from operations for fiscal 2011, 2010 and 2009, it is possible that our operations will consume cash in future periods.  Based on our currently anticipated cash needs, we believe that our current reserve of cash, cash equivalents and short-term marketable securities will be sufficient to meet our anticipated working capital requirements, obligations, capital expenditures, strategic investments and other cash needs for at least the next twelve months.  However, it is possible that we may need to raise additional funds to finance our activities during or beyond the next 12 months and our future capital requirements may vary significantly from those currently planned.  Our cash, cash equivalent and marketable security balances will continue to fluctuate based upon our ability to grow revenue, the timing of payments to us from customers and to vendors from us and the timing of inventory purchases and subsequent manufacture and sale of our products.  From time to time, we may also increase our long-term investments which will cause our marketable securities balances to fluctuate.

Our marketable securities include primarily certificates of deposit, corporate bonds, corporate commercial paper, money market funds and US agency discount notes.  We monitor all our marketable securities for impairment and if these securities are reported to have had a decline in fair value, we use significant judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of each investment including: (i) the nature of the investment; (ii) the cause and duration of any impairment; (iii) the financial condition and near term prospects of the issuer; (iv) for securities with a reported decline in fair value, our ability to hold the security for a period of time sufficient to allow for any anticipated recovery of fair value; (v) the extent to which fair value may differ from cost; and  (vi) a comparison of the income generated by the securities compared to alternative investments.  We would recognize an impairment charge if a decline in the fair value of our marketable securities is judged to be other-than-temporary.

Contractual Obligations and Commitments

We generally do not have guaranteed price or quantity commitments from any of our suppliers.  Additionally, we generally acquire products for sale to our customers based on purchase orders received as well as forecasts from such customers.  Purchase orders with delivery dates greater than twelve weeks are typically cancelable without penalty to our customers.  We currently place non-cancelable orders to purchase semiconductor wafers, other materials and finished goods from our suppliers on an eight to sixteen week lead-time basis.

The following table sets forth the amounts of payments due under specified contractual obligations as of January 29, 2011 (in thousands):

	Payments Due by Period
Contractual Obligations	Fiscal 2012		Fiscal 2013 - 2014		Fiscal 2015 - 2016		Fiscal 2017 and thereafter		Total

See Note 1, “Recent Accounting Pronouncements,” of the Notes to consolidated financial statements of this Form 10-K included in Item 8 of this report.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following discussion about our market risk disclosures involves forward-looking statements.  Actual results could differ materially from those projected in the forward-looking statements.  We face exposure to market risk from adverse movements in interest rates and foreign currency exchange rates, which could impact our operations and financial condition.  To mitigate some of the foreign currency exchange rate risk, we utilize derivative financial instruments to hedge certain foreign currency exposures.  We do not use derivative financial instruments for speculative or trading purposes.

Interest rate sensitivity:  At January 29, 2011 and January 30, 2010, we held approximately $177.5 million and $146.4 million, respectively, of cash, cash equivalents and short term and long term marketable securities.  If short-term interest rates were to decrease 10%, the decreased interest income associated with these cash, cash equivalents and marketable securities would not have a significant impact on our net income and cash flows.

Foreign currency exchange rate sensitivity:  We transact our revenues in U.S. dollars.  The U.S. dollar is our functional and reporting currency except for our subsidiaries in Canada, Denmark, France, Japan, Taiwan and Vietnam where the Canadian dollar, Danish krone, Euro, Japanese Yen, Taiwanese dollar and Vietnamese Dong are the primary financial currencies, respectively.  Additionally, a significant portion of our Israel subsidiary’s expenses are payroll related and are denominated in Israeli shekels.  This foreign currency exposure gives rise to market risk associated with exchange rate movements of the U.S. dollar against the Israeli shekel.  To the extent the U.S. dollar weakens against the Israeli shekel, our Israel subsidiary will experience a negative impact on its results of operations.  We engage in hedging activity to mitigate the risk that to the extent the U.S. dollar weakens against the Israeli shekel, our Israel subsidiary would experience a negative impact on its results of operations.

As of January 29, 2011, with the exception of our Israel operation, we had not entered into foreign exchange forward contracts to hedge certain balance sheet exposures and inter-company balances against future movements in foreign exchange rates.  For our Israel operation, we do hedge portions of our forecasted expenses that are denominated in the Israeli shekel with foreign exchange forward contracts.  As of January 29, 2011 and January 30, 2010, we had foreign exchange forward and option contracts with notional amounts of $8.5 million and $2.7 million, respectively, in place to hedge certain forecasted Israeli shekels denominated operating expenses of our Israel operation.  These contracts are designated as cash flow hedges pursuant to ASC 815, Derivatives and Hedging.  These hedges of cash flow exposures will only mitigate a portion of our foreign exchange exposure.  We will remain exposed to the currency risk of our cash flow exposures.

We maintain certain cash balances denominated in the Canadian dollar, Danish krone, Euro, Hong Kong dollar, Israeli shekel, Singapore dollar, Taiwanese dollar and Vietnamese Dong.  If foreign exchange rates were to weaken against the U.S. dollar immediately and uniformly by 10% from the exchange rate at January 29, 2011, the fair value of these foreign currency amounts would decline by $1.2 million.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Sigma Designs, Inc.

Milpitas, CA

We have audited the accompanying consolidated balance sheets of Sigma Designs, Inc. and subsidiaries ("the Company") as of January 29, 2011 and January 30, 2010, and the related consolidated statements of operations, shareholders' equity and comprehensive income, and cash flows for each of the fiscal years in the three-year period ended January 29, 2011.  We have also audited the Company's internal control over financial reporting as of January 29, 2011, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  Our audits also included the financial statement schedule listed in the Index at Part IV, Item 15.  The Company's management is responsible for these financial statements and schedule, 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 Report on Internal Control over Financial Reporting, appearing under Item 9A.  Our responsibility is to express an opinion on these financial statements and schedule and an opinion on the Company's internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects.  Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audits also included performing such other procedures as we considered necessary in the circumstances.  We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.  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 accounting principles generally accepted in the United States of America, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of January 29, 2011 and January 30, 2010, and the results of its operations and its cash flows for each of the fiscal years in the three-year period ended January 29, 2011 in conformity with accounting principles generally accepted in the United States of America.  Also, in our opinion, the related financial statement schedule for each of the fiscal years in the three-year period ended January 29, 2011, when considered in relation to the consolidated financial statements as a whole, presents fairly in all material respects the information set forth therein.  Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of January 29, 2011, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and summary of significant accounting policies

Organization and nature of operations:  Sigma Designs, Inc. (referred to collectively in these consolidated financial statements as “Sigma,” “we,” “our” and “us”) specializes in integrated system-on-chip, or SoC, solutions for the internet protocol television, or IPTV, media processor, connected home, connected media player, prosumer and industrial audio/video, and other markets.  We sell our products to manufacturers, designers and to a lesser extent, to distributors who, in turn, sell to manufacturers.

Basis of presentation:  The consolidated financial statements include Sigma Designs, Inc. and its wholly-owned subsidiaries.  All intercompany balances and transactions are eliminated upon consolidation.

Accounting period:  We follow a 52 or 53 week fiscal reporting calendar ending on the Saturday closest to January 31 each year.  Our most recent fiscal year ended on January 29, 2011 and included 52 weeks.  The fiscal years ended January 30, 2010 and January 31, 2009 included 52 weeks.  Our next fiscal year, ending on January 28, 2012, will include 52 weeks.

Reclassifications:  Certain prior fiscal year balances have been reclassified to conform to the current fiscal year presentation.

Use of estimates:  The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, or US GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period.  We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances.  Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.

Fair value of financial instruments:  For certain of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these items.  Marketable securities consist of available-for-sale securities that are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income, a component of shareholders’ equity.  The fair value of cash equivalents and certain marketable securities is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets.  

Derivative financial instruments: We account for our financial derivatives as either assets or liabilities and carry them at fair value.  We do not use derivative financial instruments for speculative or trading purposes, nor do we hold or issue leveraged derivative financial instruments.

We use foreign exchange contracts to hedge certain existing and anticipated foreign currency denominated transactions.  Unrealized gains and losses arising from the effective portion of foreign exchange contracts that are designated as cash flow hedging instruments are recorded in accumulated other comprehensive income and are subsequently reclassified into earnings in the same period or periods during which the underlying transactions affect earnings.  Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.  Gains and losses arising from changes in the fair values of foreign exchange contracts that are not designated as hedging instruments are recognized in current earnings.

We formally document relationships between hedging instruments and associated hedged items.  This documentation includes: identification of the specific foreign currency asset, liability or forecasted transaction being hedged; the nature of the risk being hedged; the hedge objective; and, the method of assessing hedge effectiveness.  Hedge effectiveness is formally assessed, both at hedge inception and on an ongoing basis, to determine whether the derivatives used in hedging transactions are highly effective in offsetting changes in foreign currency denominated assets, liabilities and anticipated cash flows of hedged items.

Cash and cash equivalents:  We consider all highly liquid debt instruments purchased with a remaining maturity of 90 days or less to be cash equivalents.

Short and long-term marketable securities:  Short-term marketable securities represent highly liquid debt instruments with a remaining maturity date at acquisition date of greater than 90 days but less than one year and are stated at fair value.  Long-term marketable securities represent securities with contractual maturities greater than one year from the date of acquisition.  We classify our marketable securities as available-for-sale because the sale of such securities may be required prior to maturity.  The difference between amortized cost (cost adjusted for amortization of premiums and accretion of discounts, which is recognized as an adjustment to interest income) and fair value, representing unrealized holding gains or losses, are recorded separately as a component of accumulated other comprehensive income within shareholders’ equity.  Any gains and losses on the sale of marketable securities are determined on a specific identification basis.  We monitor all of our marketable securities for impairment and if these securities are reported to have a decline in fair value, we use significant judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of each investment including: (i) the nature of the investment; (ii) the cause and duration of any impairment; (iii) the financial condition and future prospects of the issuer; (iv) for securities with a reported decline in fair value, our ability to hold the security for a period of time sufficient to allow for any anticipated recovery of fair value; (v) the extent to which fair value may differ from cost; and  (vi) a comparison of the income generated by the securities compared to alternative investments.  We recognize an impairment charge if a decline in the fair value of our marketable securities is judged to be other-than-temporary.

55

Accounts receivable:  We defer recognition of revenue and the related receivable when we cannot estimate whether collectability is reasonably assured at the time products and services are delivered to our customer.  We also provide allowances for bad debt and sales returns.  In establishing the allowance for bad debt, we review the customer’s payment history and information regarding their credit worthiness.  In establishing the allowance for sales returns, we make estimates of potential future returns of products for which revenue has been recognized in the current period, including analyzing historical returns, current economic trends and changes in customer demand and acceptance of our products.  In fiscal 2011, 2010 and 2009, we recorded provisions for sales returns, discounts and bad debt in the total amounts of $0.3 million, $0.5 million and $0.9 million, respectively.  If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, or future product returns increased, additional allowances may be required.

Inventories:  Inventories are stated at the lower of standard cost which approximates actual cost on a first-in, first-out basis, or market value.  We evaluate our ending inventories for excess quantities and obsolescence on a quarterly basis.  This evaluation includes analysis of historical and forecasted unit sales by product.  A provision is recorded for inventories on hand in excess of forecasted demand.  In addition, we write off inventories that become obsolete.  Obsolescence is determined from several factors, including competitiveness of product offerings, market conditions and product life cycles.  Increases to the allowance for excess and obsolete inventory are charged to cost of revenue.  At the point of the loss recognition, a new, lower-cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.  If this lower-cost inventory is subsequently sold, we will realize higher gross margins for those products.

As a result of our inventory valuation reviews, we charged approximately $0.5 million, $0.3 million and $2.1 million to cost of revenue for fiscal 2011, 2010 and 2009, respectively.

Software, equipment and leasehold improvements:  Software, equipment and leasehold improvements are stated at cost.  Software includes intellectual property that we purchase for incorporation into our product designs.  Depreciation and amortization are computed using the straight-line method based on the useful lives of the assets (one to five years) or the lease term if shorter.  The allowance for leasehold improvements received from the landlord for improvements to our facility is amortized using the straight-line method over the lesser of the remaining lease term or the useful life of the leasehold improvements.  Repairs and maintenance costs are expensed as incurred.

Long-term investments:  Investments in private equity securities of less than 20% owned companies are accounted for using the cost method unless we can exercise significant influence or the investee is economically dependent upon us, in which case the equity method is used.  We evaluate our long-term investments for impairment annually or whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable.

Goodwill and intangible assets:  Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired.  The amounts and useful lives assigned to finite lived intangible assets acquired, other than goodwill, impact the amount and timing of future amortization.

We review goodwill and intangible assets with indefinite lives for impairment annually and whenever events or changes in circumstances indicate the carrying value may not be recoverable.  An impairment charge is recorded if the carrying value exceeds the assets’ fair value.  Intangible assets with finite useful lives are tested for impairment annually or if certain impairment indicators are identified.  We assess the carrying value of long-lived assets whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable.  Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions.  These estimates and assumptions include revenue growth rates and forecasted operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions and determination of appropriate market comparables.  We base our fair value estimates on assumptions we believe to be reasonable.  Actual future results may differ from those estimates.

Revenue recognition: We derive our revenue from three sources: product sales, and, to a lesser extent, product development contracts and service contracts.  We recognize revenue for product sales and service contracts when persuasive evidence of an arrangement exists, delivery has occurred or service has been rendered, the fee is fixed or determinable and collectability is reasonably assured.

Revenue from product sales to original equipment manufacturers, or OEMs, distributors and end users is recognized upon shipment when shipping terms are FOB shipping point, and revenue is deferred when we cannot reasonably estimate the amount of returns or where collectability is not assured.  When revenue is deferred, it is subsequently recognized when collection becomes probable and returns are estimable.  Allowances for sales returns, discounts and warranty costs are recorded at the time that the associated revenue is recognized.

56

Foreign currency:  The functional currency of our foreign subsidiaries is either the U.S. dollar or the local currency of each country.  Where the local currency is the functional currency, gains and losses from the translation of the financial statements of the foreign subsidiaries are included in shareholders’ equity.  Transaction gains and losses, which are included in interest and other income, net, in the accompanying consolidated statements of operations were net losses of approximately $0.2 million, $0.6 million and $34,000 for fiscal 2011, 2010 and 2009, respectively.

Concentration of credit risk:  Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, short-term and long-term marketable securities, restricted cash, long-term investments and accounts receivable.  Our cash, cash equivalents, short-term and long-term marketable securities and restricted cash are on deposit with major financial institutions.  Such deposits may be in excess of insured limits.  We believe that the financial institutions that hold our cash and cash equivalents, short-term and long-term marketable securities and restricted cash are financially sound and, accordingly, minimal credit risk exists with respect to these balances.  We have not experienced any investment losses due to institutional failure or bankruptcy.  We perform ongoing credit evaluations of our customers and generally do not require collateral for sales on credit.  We review our accounts receivable balances to determine if any receivables will potentially be uncollectible and include any amounts that are determined to be uncollectible in our allowance for doubtful accounts.

Income taxes:  Income taxes are accounted for under an asset and liability approach.  Deferred income taxes reflect the net tax effects of any temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts reported for income tax purposes, and any operating losses and tax credit carryforwards.  Deferred tax liabilities are recognized for future taxable amounts and deferred tax assets are recognized for future deductions, net of any valuation allowance, to reduce deferred tax assets to amounts that are considered more likely than not to be realized.  

The impact of an uncertain income tax position on the income tax return must be recognized as the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority.  An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained.  Additionally, ASC 740, Income Taxes, provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.  The total amount of unrecognized tax benefits as of January 29, 2011 was $17.6 million.

Stock-based compensation:  We measure and recognize compensation expense for all stock-based payment awards made to employees and directors based on estimated fair values.  We estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model.  The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service period in our consolidated statements of operations.  We estimate forfeitures at the time of grant and revise our estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The effect of recording employee stock-based compensation expense on the consolidated statements of operations for fiscal 2011, 2010 and 2009 was as follows (in thousands):

	Years Ended
	January 29, 2011		January 30, 2010		January 31, 2009
Stock-based compensation expense by type of award:
Stock options	$	11,639	$	7,998	$	11,954
Employee stock purchase plan awards		920		760		663
Total stock-based compensation expense	$	12,559	$	8,758	$	12,617

Long-lived assets: Long-lived assets, including purchased intangible assets, are evaluated for impairment whenever events or changes in circumstances, such as a change in technology, indicate that the carrying amount of an asset may not be recoverable.  An impairment loss would be recognized when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposal is less than its carrying amount.

Research and development costs: Costs incurred in the research and development of our products are expensed as incurred.  Costs associated with the development of software are expensed prior to the establishment of technological feasibility and capitalized in certain cases thereafter until the product is available for general release to customers.

57

Comprehensive income: Comprehensive income consists of net income and other comprehensive income (loss).  Other comprehensive income (loss) includes certain changes in equity that are excluded from results of operations.  Specifically, foreign currency translation adjustments, unrealized gains or losses on marketable securities and unrealized gains and losses arising from the effective portion of foreign exchange contracts that are designated as cash flow hedging instruments are included in accumulated other comprehensive income (loss) in the accompanying consolidated balance sheets.

Recent accounting pronouncements:  In December 2010, the FASB amended its existing guidance for goodwill and other intangible assets.  This authoritative guidance modifies 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 there are qualitative factors indicating that it is more likely than not that a goodwill impairment exists.  The qualitative factors are consistent with the existing guidance which requires goodwill of a reporting unit to 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.  This authoritative guidance becomes effective for us in our first quarter of fiscal 2012.  The implementation of this authoritative guidance is not expected to have a material impact on our financial position or results of operations.

In December 2010, the FASB issued authoritative guidance on business combinations.  This authoritative guidance requires a public entity that presents comparative financial statements to disclose the revenue and earnings of the combined entity as though the business combinations that occurred during the current year had occurred as of the beginning of the prior annual reporting period.  In addition, this authoritative guidance expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings.  This authoritative guidance is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010.  We will comply with this authoritative guidance beginning in our first quarter of fiscal 2012.

In January 2010, the FASB issued authoritative guidance for fair value measurements, which requires additional disclosures and clarifications to existing disclosures.  This authoritative guidance requires a reporting entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and also to describe the reasons for these transfers.  This authoritative guidance also requires enhanced disclosure of activity in Level 3 fair value measurements.  The new disclosures and clarifications of existing disclosures for Level 1 and Level 2 fair value measurements became effective for us in first quarter of fiscal 2011.  Disclosures regarding activity within Level 3 fair value measurements become effective the first interim reporting period beginning after December 15, 2010.  We will comply with this authoritative guidance beginning in our first quarter of fiscal 2012.  See Note 4 for information and related disclosures regarding our fair value measurements.

2. Share repurchase program

On February 27, 2008, we announced that our Board of Directors had approved a share repurchase program that authorized us to repurchase up to 2.0 million shares of our common stock.  On March 18, 2008, we announced that our Board of Directors had approved an increase of 3.0 million additional shares to the program, resulting in a total amount authorized to be repurchased under the share repurchase program of 5.0 million shares.  The share repurchase program had a one-year term, and thus, terminated on March 17, 2009.  We purchased a cumulative total of approximately 4.2 million shares of our common stock pursuant to the repurchase program for an aggregate purchase price of $85.9 million at an average price of $20.50 per share in fiscal 2009.  We did not repurchase any shares under this program in fiscal 2010 before the program was terminated on March 17, 2009.

Our marketable securities include primarily certificates of deposit, corporate bonds, corporate commercial paper, money market funds and US agency discount notes.  

We previously held auction rate securities, or ARS.  ARS are bought and sold in the market place through a bidding process sometimes referred to as a “Dutch auction.”  Subsequent to February 2008, all auctions involving the ARS that we held failed.  In October 2008, we accepted an offer of a comprehensive settlement agreement from our cash investment advisor, UBS, in which all the ARS that we held could be redeemed at par value.  During the second quarter of fiscal 2011, all of the ARS that we held were redeemed at par value.

4. Fair values of assets and liabilities

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).”  The accounting standards establish a consistent framework for measuring fair value and disclosure requirements about fair value measurements and among other things, requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

Fair value hierarchy

The accounting standards discuss valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost).  The standards utilize a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels.  The following is a brief description of those three levels:

· Level 1 - Valuation is based upon quoted prices for identical instruments traded in active markets.

· Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market.

· Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market.  These unobservable assumptions reflect our estimate of assumptions that market participants would use in pricing the asset or liability.  Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.

Determination of Fair Value

Our cash equivalents and marketable securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency.  The types of marketable securities valued based on quoted market prices in active markets include most U.S. government and agency securities, sovereign government obligations, money market securities and certain corporate obligations with high credit ratings and an ongoing trading market.

59

Our foreign currency derivative instruments are classified as Level 2 because they are valued using quoted prices and other observable data of similar instruments in active markets.

We also classified the ARS that we previously held within Level 3.  As of January 30, 2010, the fair value of the ARS was $40.8 million.  During the second quarter of fiscal 2011, all of the ARS that we held were redeemed at par value.

In connection with our acquisition of CopperGate in November 2009, we agreed to pay up to an aggregate of $5.0 million in cash to specified CopperGate employees if certain milestones are achieved over a specified period.  We estimated the fair value of this contingent consideration based on the probability that certain milestones would be met and the payments would be made on the targeted dates outlined in the acquisition agreement.  In developing these estimates, we considered the revenue projections and historical results of CopperGate.  This fair value measurement is based on significant inputs not observed in the market.

  The tables below presents the balances of our assets and liabilities measured at fair value on a recurring basis as of January 29, 2011 and January 30, 2010 (in thousands):

Assets measured and recorded at fair value on a non-recurring basis

Our non-marketable convertible promissory note and preferred stock investments in privately-held venture capital funded technology companies are recorded at fair value only if an impairment charge is recognized.  In fiscal 2009 and 2010, we purchased shares of preferred stock in a privately-held venture capital funded technology company at a total investment cost of $2.0 million and we purchased a convertible note receivable from the same company with a face value equal to the cost of $3.0 million, convertible into the issuer’s preferred stock under certain circumstances, bearing interest at a rate of 9% per annum which became callable on November 30, 2009.  During our second quarter of fiscal 2011, the issuer of the $3.0 million convertible promissory note and the $2.0 million of preferred stock determined that additional funding would be required to continue operations.  This convertible note receivable was classified within Level 3.  This issuer held discussions with various parties, and a third party made a preliminary offer to purchase substantially all of the issuer’s assets at a price that would not allow us to collect any amount on our investments.  Based on the available information, we determined that the value of our investments in this issuer had suffered an other-than-temporary decline in value.  Accordingly, at July 31, 2010, we recorded an impairment charge of $5.2 million to fully write down the carrying value of the convertible promissory note, accrued interest and preferred stock investment due to our expected inability to recover any value from it.  At January 29, 2011, we continue to keep this reserve for impairment, as no further information has come to our attention that would change our conclusion.  These investments were classified within Level 3.

5. Derivative financial instruments

Effective November 10, 2009, we adopted ASC 815, Derivatives and Hedging (formerly SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities).  The initial adoption of ASC 815 had no financial impact on our consolidated financial statements and only required additional financial statement disclosures.  We applied the requirements of this standard on a prospective basis.  Accordingly, disclosures related to interim periods prior to the date of adoption have not been presented.

Foreign exchange contracts are recognized either as assets or liabilities on the balance sheet at fair value at the end of each reporting period.

Cash flow hedges

We currently use and expect to continue to use foreign currency derivatives such as forward and option contracts as hedges against anticipated transactions denominated in foreign currencies.  We enter into these contracts to protect ourselves against the risk that the eventual net cash flows will be adversely affected by changes in foreign exchange rates.

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings.  Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.

As of January 29, 2011, we had foreign exchange contracts to sell up to approximately $8.5 million for a total amount of approximately New Israeli Shekels, or NIS, 31.6 million, that would mature on or before December 30, 2011.  In fiscal 2011, we recognized gains of $259,000 as a result of derivative instruments.  As of January 30, 2010, we had foreign exchange contracts to sell up to approximately $4.5 million for a total amount of approximately NIS 17.0 million, that matured on or before January 29, 2011.  In fiscal 2010, we recognized gains of $41,000 as a result of derivative instruments.

Fiscal 2010 foreign exchange contracts	$	82	$	114	Operating expenses and cost of revenue	$	(73	)	Interest and other income, net

6. Restricted cash

As of January 29, 2011 and January 30, 2010, we had $1.6 million and $1.5 million, respectively, of restricted cash related to a deposit pledged to a financial institution with regard to our foreign exchange hedging transactions and an office operating lease.

7. Investments in privately held companies

During fiscal 2009, we purchased shares of preferred stock in two privately-held venture capital funded technology companies (“Issuer A” and “Issuer B”) at a total investment cost of $3.0 million.  In the fourth quarter of fiscal 2010, we purchased additional shares of preferred stock in Issuer B at a cost of $1.0 million.  In the third quarter of fiscal 2010, we purchased a convertible note from Issuer A with a face value equal to the cost of $3.0 million which is convertible into the issuer’s preferred stock under certain circumstances, bears interest at a rate of 9% per annum and became callable after November 30, 2009.  In the third quarter of fiscal 2011, we purchased shares of preferred stock in another privately-held technology company (“Issuer C”) at a total investment cost of $1.0 million.  In the fourth quarter of fiscal 2011, we purchased shares of preferred stock in another privately-held technology company (“Issuer D”) at a total investment cost of $1.0 million.  Additionally, in the fourth quarter of fiscal 2011, we purchased a convertible note from another privately-held technology company (“Issuer E”) with a face value equal to the cost of $0.3 million.  This amount of $0.3 million will convert to a quantity of equity upon any closing of financing prior to December 31, 2012.  As of January 29, 2011, we have investments in the amount of zero, net of impairment reserve in Issuer A, $2.0 million in Issuer B, $1.0 million in Issuer C, $1.0 million in Issuer D and $0.3 million in Issuer E for a total investment of $4.3 million in these five companies.  Three of our four directors hold equity interests in Issuer A in which we invested an aggregate of $5.0 million and one of these directors is also a director of Issuer A.  In the aggregate, these equity and debt interests do not rise to the level of a material or a controlling interest in Issuer A.  Our board of directors appointed our director who has no interest in Issuer A to evaluate each investment in Issuer A and to recommend appropriate action to the board of directors.  All investment transactions with Issuer A were approved and recommended by this independent director and made as the result of a negotiation process.

62

During our second quarter of fiscal 2011, Issuer A determined that additional funding would be required to continue operations.  Issuer A held discussions with various parties, and a third party made a preliminary offer to purchase substantially all of its assets at a price that would not allow us to collect any amount on our investments in Issuer A.  Based on the available information, we determined that the value of our investment in Issuer A had suffered an other-than-temporary decline in value.  Accordingly, at July 31, 2010, we recorded an impairment charge of $5.2 million to fully write down the carrying value of the preferred stock equity investment and fully reserve the convertible note receivable, including accrued interest, due to our expected inability to collect any amounts in connection with these investments.  At January 29, 2011, we continue to keep this reserve for impairment, as no further information has come to our attention that would change our conclusion.

At January 29, 2011 and January 30, 2010, the convertible note in Issuer A was valued at zero and $3.1 million, respectively, equaling its cost plus accrued interest, net of reserve for impairment and all our equity investments in privately held companies were valued at $4.3 million and $4.0 million, respectively, representing their cost, net of reserve for impairment.

Software includes intellectual property that we purchase for incorporation into our product designs.  We begin amortizing such software at the time that we begin shipment of the products that incorporate such software.  At January 29, 2011 and January 30, 2010, we had $9.1 million and $6.4 million, respectively, of such software which we have not yet begun to amortize.  Software, equipment and leasehold improvement depreciation and amortization expense for fiscal 2011, 2010 and 2009 was $9.3 million, $6.4 million and $4.2 million, respectively.

10. Acquisitions

Fiscal 2010 Acquisition

           On November 10, 2009, we acquired all of the issued and outstanding share capital, including vested stock options, of CopperGate Communications Ltd., or CopperGate, pursuant to an Acquisition Agreement dated October 12, 2009, as amended by the First Amendment to Acquisition Agreement dated November 10, 2009 (the “Agreement”).  CopperGate is a provider of silicon-based modem solutions enabling distribution of media-rich digital content over all three types of wires in the home: coaxial cable, phone and power.  CopperGate solutions are deployed by service providers enabling the delivery of HDTV, VoIP and fast internet services.  CopperGate is headquartered in Tel Aviv, Israel with offices in the U.S. and Taiwan.  Under the terms of the Agreement, we paid approximately $116.0 million in cash of which approximately $11.6 million is being held in escrow for a period of 18 months and issued an aggregate of 3,931,352 shares of our common stock, of which 393,138 shares are being held in escrow for a period of 18 months from the closing date.  At the closing, we also assumed all unvested CopperGate options and, as a result, issued unvested options to purchase an aggregate of 574,881 shares of our common stock, which options will vest over time.  Under the terms of the Agreement, we also agreed to pay up to an aggregate of $5.0 million in cash to specified CopperGate employees provided that certain milestones are achieved over a specified period of time.

63

 In connection with the CopperGate acquisition, we obtained a valuation of the net assets acquired in order to allocate the purchase price to the acquired assets.  The total purchase price was allocated to CopperGate net tangible and intangible assets based upon fair values as of November 10, 2009.  The excess purchase price over the value of the net tangible and identifiable intangible assets was recorded as goodwill.  The purchase price in the transaction was allocated as follows (in thousands except years):

	Amount
Cash consideration	$	115,956
Common stock issued		48,513
Contingent consideration		4,900

Total consideration	$	169,369

               A $4.9 million liability was recorded for the estimated acquisition date fair value of the acquisition-related contingent consideration based on the probability of the achievement of revenue and product related milestones.  The estimated fair value of the contingent consideration was based on the probability that these milestones will be met and the payments will be made on the targeted dates outlined in the acquisition agreement.  In developing these estimates, we considered the revenue projections and historical results of CopperGate.  Any change in the fair value of the acquisition-related contingent consideration subsequent to the closing date, including changes from events after the closing date, will be recognized in earnings in the period the estimated fair value changes.

The fair value of the common stock issued was determined based on the closing market price of our common shares on the acquisition date.

As a result of the acquisition, we recorded $43.2 million of tangible assets consisting of $26.8 million of cash and cash equivalents and marketable securities, $1.0 million of restricted cash, $2.6 million of account receivables, $9.3 million of inventories, $1.1 million of property and equipment and $2.4 million of other assets.  We recorded $23.4 million of liabilities, consisting of $2.3 million of accounts payables, $6.9 million of accrued liabilities and $14.2 million of tax liabilities.

The amounts of revenue and net loss of CopperGate included in our consolidated statement of operations from the acquisition date to the period ended January 30, 2010 are as follows (in thousands):

Fiscal 2009 Acquisitions

On December 19, 2008, we acquired Zensys Holdings Corporation, or Zensys, a wireless start-up company for $13.2 million in cash including transaction costs.  Zensys Holdings Corporation, based in Fremont, California, is a developer of single-chip RF solutions called Z-Wave®.  As part of the acquisition, twenty-eight employees joined us.  Zensys has a research and development office in Denmark.

64

In connection with the Zensys acquisition, we obtained a valuation of the net assets acquired in order to allocate the purchase price to the acquired assets.  The total purchase price was allocated to Zensys’ net tangible and intangible assets based upon fair values as of December 19, 2008.  The excess purchase price over the value of the net tangible and identifiable intangible assets was recorded as goodwill.  The purchase price in the transaction was allocated as follows (in thousands except years):

We acquired in-process research and development, or IPR&D, of $10.7 million in our acquisition of CopperGate.  The fair value of the IPR&D was determined through estimates and valuation techniques based on the terms and details of the acquisition.  The amounts allocated to IPR&D will not begin to be expensed until completion of the related project, as it was determined that the underlying project had not reached technological feasibility at the date of acquisition.  The IPR&D project represents our next generation HomePNA product with backward compatibility to our current HomePNA and HomePlug AV products and providing increased data rates, ease of use and quality of service (QoS).  We expect to complete development on this project in the second half of fiscal 2012.  Upon completion of development, we will determine and begin amortization of the acquired IPR&D over its useful life.

Amortization expense related to acquired intangible assets was $18.3 million, $6.8 million and $3.0 million for fiscal 2011, 2010 and 2009, respectively.  As of January 29, 2011, excluding IPR&D, we expect the amortization expense in future periods to be as follows, (in thousands):

Rent expense, recorded on a straight-line basis, was $2.6 million, $2.0 million and $1.5 million for fiscal 2011, 2010 and 2009, respectively.  

Purchase commitments

We place non-cancelable orders to purchase semiconductor products from our suppliers on an eight to twelve week lead-time basis.  As of January 29, 2011, the total amount of outstanding non-cancelable purchase orders was approximately $23.0 million.

Indemnifications

In certain limited circumstances, we have agreed and may agree in the future to indemnify certain customers against patent infringement claims from third parties related to our intellectual property.  In these limited circumstances, the terms and conditions of sale generally limit the scope of the available remedies to a variety of industry-standard methods including, but not limited to, a right to control the defense or settlement of any claim, procure the right for continued usage, and a right to replace or modify the infringing products to make them non-infringing.  Such indemnification provisions are accounted for in accordance with ASC 450, Contingencies.  To date, we have not incurred or accrued any significant costs related to any claims under such indemnification provisions.

Royalties

We pay royalties for the right to sell certain products under various license agreements.  During fiscal 2011, 2010 and 2009, we recorded royalty expense of $3.2 million, $2.9 million and $2.0 million, respectively, which was recorded to cost of revenue.

Our wholly owned subsidiary, CopperGate, participated in programs sponsored by the Office of the Chief Scientist of Israel's Ministry of Industry, Trade and Labor, or the OCS, for the support of research and development activities that we conducted in Israel.  Through January 29, 2011, CopperGate had obtained grants from the OCS aggregating to $4.8 million for certain of our research and development projects in Israel.  We completed the most recent of these projects in 2007.  We are obligated to pay royalties to the OCS, amounting to 3.5% to 4.5% of the sales of certain products up to an amount between 120% and 150% of the grants received.  As of January 29, 2011, our remaining obligation under these programs was $0.6 million.

Contingencies

Litigation

We are not currently a party to any material legal proceedings.  From time to time, we are involved in claims and legal proceedings that arise in the ordinary course of business.  We expect that the number and significance of these matters will increase as our business expands.  In particular, we could face an increasing number of patent and other intellectual property claims as the number of products and competitors in our industry grows.  Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources, or cause us to enter into royalty or licensing agreements which, if required, may not be available on terms favorable to us or at all.  If an unfavorable outcome were to occur against us, there exists the possibility of a material adverse impact on our financial position and results of operations for the period in which the unfavorable outcome occurs and, potentially, in future periods.

15. Net income per share

Basic net income per share for the periods presented is computed by dividing net income by the weighted average number of common shares outstanding.  Diluted net income per share is computed by including dilutive options.

16. Equity incentive plans and employee benefits

Stock incentive plans

We have adopted equity incentive plans that provide for the grant of stock option awards to employees, directors and consultants which are designed to encourage and reward their long-term contributions to us and provide an incentive for them to remain with us.  These plans also align our employees’ interest with the creation of long-term shareholder value.  As of January 29, 2011, we have four stock option plans: the 2003 Director Stock Option Plan (the “2003 Director Plan”), the 2001 Stock Plan (the “2001 Plan”), the 2009 Stock Incentive Plan (the “2009 Incentive Plan”) and the CopperGate Share Option Plan (the “CopperGate Plan”).  The 2009 Incentive Plan was approved by our shareholders in July 2009 along with the approval of a one-time stock option exchange program.  The CopperGate Plan was assumed by us in connection with the acquisition of CopperGate in November 2009.

The exchange program began on August 24, 2009 and concluded on September 22, 2009.  Under the exchange program, eligible employees were permitted to exchange outstanding stock options granted under our 2001 Plan prior to June 2008 with exercise prices equal to or greater than $20.25 per share for a lesser number of stock options that were granted following the expiration of the exchange program at a ratio of 1 share in the replacement option for every 1.5 shares exchanged from eligible options.  Our directors and executive officers were not eligible to participate in the option exchange program.  As a result, on September 22, 2009, pursuant to the terms of the exchange program, we accepted for exchange and cancelled options to purchase an aggregate of 663,737 shares of our common stock under the 2001 Plan.  On September 23, 2009, we issued replacement options to purchase an aggregate of 442,550 shares of our common stock in exchange for the options tendered under our 2001 Plan.  These replacement options have a strike price of $15.25 with a 5-year vesting schedule and 8-year term, each commencing on September 23, 2009.

Our 2009 Incentive Plan provides for the grant of stock options, restricted stock, restricted stock units, other stock-related awards and performance awards that may be settled in cash, stock or other property.  In July 2009, 2,900,000 shares of common stock were reserved for issuance under the 2009 Incentive Plan.  In addition, up to 1,000,000 shares of common stock that were subject to stock awards outstanding under the 2001 Plan but terminated prior to exercise and would otherwise be returned to the share reserves under our 2001 Plan may become available for issuance under the 2009 Incentive Plan. 

As of January 29, 2011, 1,067,974 shares were available for future grants under our stock incentive plans.  Additionally, up to 940,021 shares of common stock subject to stock awards outstanding under the 2001 Plan could become available for issuance under the 2009 Incentive Plan.  As of September 23, 2009, the 2001 Plan and the 2003 Director Plan were closed for future grants, however, these plans will continue to govern all outstanding options that we originally granted from each plan.

The total stock option activities and balances of our stock option plans are summarized as follows:

The aggregate intrinsic value, as of January 29, 2011, in the table above represents the total pretax intrinsic value, based on our closing stock price of $13.93 on that date which would have been received by the option holders had all options holders exercised their options as of that date.  The aggregate exercise date intrinsic value of options that were exercised under our stock plans during fiscal 2011, 2010 and 2009 equaled $3.1 million, $1.3 million and $12.5 million, respectively, determined as of the exercise date.  The total fair value of options which vested during fiscal 2011, 2010 and 2009 was $12.1 million, $6.8 million and $14.0 million, respectively.  

The options outstanding and currently exercisable at January 29, 2011 were in the following exercise price ranges:

As of January 29, 2011, the unrecorded stock-based compensation balance related to stock options outstanding excluding estimated forfeitures was $30.9 million and will be recognized over an estimated weighted average amortization period of 3.4 years.  The amortization period is based on the expected remaining vesting term of the options.

Restricted Stock Awards

The Company granted a total of 85,137 shares of restricted stock awards for the year ended January 29, 2011.  The Company values restricted stock awards using the intrinsic value on the date of grant.  The total grant date fair value of restricted stock awards granted in the fiscal year ended January 29, 2011 was $1.1 million.

Employee stock purchase plan

Under our 2001 Employee Stock Purchase Plan (the “2001 Purchase Plan”), employees are granted the right to purchase shares of common stock at a price per share that is 85% of the fair market value at the beginning or end of each six-month offering period, whichever is lower.  As of January 29, 2011, no shares under the 2001 Purchase Plan remain available for future purchase.  The 2001 Purchase Plan will expire on April 3, 2011.

In July 2010, our shareholders approved the 2010 Employee Stock Purchase Plan (the “2010 Purchase Plan”).  A total of 2,500,000 shares were reserved for issuance under the 2010 Purchase Plan which replaced the 2001 Purchase Plan as of January 1, 2011.  The 2010 Purchase Plan is implemented by offerings of rights to eligible employees.  Each offering will be in such form and will contain such terms and conditions as our Board or a committee thereof will deem appropriate, subject to compliance with applicable regulations.  The provisions of separate offerings need not be identical.  Under the terms of the offering that commenced on January 1, 2011, eligible employees may authorize payroll deductions of up to 15% of their regular base salaries to purchase common stock at 85% of the fair market value of our common stock at the beginning or end of the six-month offering period, whichever is lower.  The maximum number of shares that can be purchased in any single offering period is limited under the terms of the offering, including a limitation that an eligible employee cannot purchase in any single offering period more than 1,500 shares of common stock, as adjusted in accordance with the terms of the 2010 Purchase Plan.  The terms of this offering will automatically apply to future offerings under the 2010 Purchase Plan unless modified by the Board or a committee thereof.

During fiscal 2011, 2010 and 2009, 334,192, 207,798 and 153,796 shares of our common stock were purchased at an average price of $8.43, $8.86 and $9.48 per share, respectively.  As of January 29, 2011, we had reserved a total of 2,500,000 shares of common stock for issuance under the 2010 Purchase Plan, of which none had been granted.  

Valuation of stock-based compensation

The fair value of stock-based compensation awards is estimated at the grant date using the Black-Scholes option valuation model.  The determination of fair value of stock-based compensation awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables.  These variables include, but are not limited to, our expected stock price volatility over the term of the awards and actual employee stock option exercise behavior.

The fair value of each option and employee stock purchase right was estimated on the date of grant using the Black-Scholes option valuation model with the following weighted-average assumptions:

	Years Ended
	January 29,	January 30,	January 31,
Stock options	2011	2010	2009
Expected volatility	55.02%	59.53%	68.11%
Risk-free interest rate	2.54%	2.62%	2.46%
Expected term (in years)	5.94	5.91	5.95
Dividend yield	None	None	None
Weighted average fair value at grant date	$ 5.95	$ 6.54	$ 10.08

	Years Ended
	January 29,	January 30,	January 31,
Employee stock purchase plan rights	2011	2010	2009
Expected volatility	37.52%	52.92%	89.90%
Risk-free interest rate	0.21%	0.23%	1.05%
Expected term (in years)	0.50	0.50	0.50
Dividend yield	None	None	None
Weighted average fair value at grant date	$ 2.94	$ 3.91	$ 4.69

The computation of the expected volatility assumptions used in the Black-Scholes calculations for new grants and purchase rights is based on the historical volatility of our stock price, measured over a period equal to the expected term of the grants or purchase rights.  The risk-free interest rate is based on the yield available on U.S. Treasury Strips with an equivalent remaining term.  The expected term life of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards and vesting schedules.  The expected term of purchase rights is the period of time remaining in the current offering period.  The dividend yield assumption is based on our history of not paying dividends and assumption of not paying dividends in the future.

Non-employee related stock-based compensation expenses

In accordance with the provisions of ASC 718, Compensation—Stock Compensation, and ASC 505, Equity, we recorded stock-based compensation expense for options issued to non-employees based on the fair value of the options as estimated on the measurement date which is typically the grant date, using the Black-Scholes option pricing model.  The Black-Scholes option pricing model for fiscal 2011 includes the following weighted average assumptions; expected stock price volatility of 52%, weighted average contractual term of 5.75 years, dividend yield of zero percent and risk-free interest rates of 2.2%.  Total non-employee stock-based compensation recorded during fiscal 2011, 2010 and 2009 was $18,000, $35,000 and $56,000, respectively.

401(k) tax deferred savings plan

We maintain a 401(k) tax deferred savings plan for the benefit of qualified employees who are U.S. based.  Under the 401(k) tax deferred savings plan, U.S. based employees may elect to reduce their current annual taxable compensation up to the statutorily prescribed limit, which was $16,500 in calendar year 2010.  Employees age 50 or over may elect to contribute an additional $5,500.  We sponsor a matching contribution program whereby we match contributions made by each employee at a rate of $0.25 per $1.00 contributed.  The matching contributions we made to the 401(k) tax deferred savings plan totaled $0.7 million, $0.6 million and $0.5 million for fiscal 2011, 2010 and 2009, respectively.

Group registered retirement savings plan

We maintain a Group Registered Retirement Savings Plan, or GRRSP, for the benefit of qualified employees who are based in Canada.  Under the GRRSP, Canadian based employees may elect to reduce their annual taxable compensation up to the statutorily prescribed limit which is $22,000 Canadian in calendar year 2010.  We have a matching contribution program under the GRRSP whereby we match employee contributions made by each employee up to 2.5% of their annual salary.  The matching contributions to the GRRSP totaled $87,000, $86,000 and $69,000 for fiscal 2011, 2010 and 2009, respectively.

71

Retirement pension plan

We maintain a Retirement Pension Plan for the benefit of qualified employees who are based in Denmark.  Under the Retirement Pension Plan, Denmark-based employees may elect to reduce their annual taxable compensation up to their annual salary.  We have a matching contribution program whereby we will contribute 3.0% of our employee’s annual salary.  Our matching contribution to the Retirement Pension Plan totaled $119,000, $54,000 and $11,000 for fiscal 2011, 2010 and 2009, respectively.

Severance plan

We maintain a severance plan for Israeli employees pursuant to Israel's Severance Pay Law based on the most recent salary of the employees multiplied by the number of years of employment.  Employees are entitled to one month salary for each year of employment or a portion thereof.  As of January 29, 2011, we have an accrued severance liability of $1.4 million.

ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that we assess that realization is “more likely than not.”  Deferred income taxes result principally from differences in the recognition of certain assets and liabilities for tax and financial reporting purposes and the tax effect of tax loss carryforwards.  As of January 29, 2011, net operating loss carryforwards amounted to approximately $46.1 million and $13.0 million for federal and California tax purposes, respectively, which will begin to expire in 2011 through 2030.  We also had federal and state research credit carryovers of $12.4 million and $11.9 million, respectively.  If not utilized, the federal credits begin to expire in 2016.  The state research credit has no expiration.  Of the total net operating loss carryover, the tax effect of $37.6 million federal and $3.6 million state losses will be recorded to additional paid-in capital when utilized in the future.  We also have $28.9 million foreign operating loss carryforwards through the acquisition of a foreign operation.  As of January 29, 2011, we maintained a valuation allowance against foreign net operating losses and California deferred tax assets.  The valuation allowance increased by $0.7 million in fiscal 2011.

Net operating losses and tax credit carryforwards as of January 29, 2011 are as follows (in thousands):

			Expiration
	Amount		Years
Net operating losses, federal	$	46,091	2014 - 2030
Net operating losses, state		12,971	2011 - 2018
Net operating losses, foreign		28,910	Indefinite
Tax credits, federal		12,357	2016 - 2031
Tax credits, state		11,940	Indefinite

Current federal and California tax laws include substantial restrictions on the utilization of net operating losses and tax credits in the event of an “ownership change” of a corporation.  Accordingly, our ability to utilize net operating loss and tax credit carryforwards may be limited as a result of such ownership changes.  Such a limitation could result in the expiration of carryforwards before they are utilized.

In December 2010, a retroactive two-year extension of the federal R&D credit through the end of calendar year 2011 was signed into law.  The federal R&D credit had previously expired at the end of calendar year 2009.  As a result of this change in federal tax law, the Company recorded a tax benefit for the federal R&D credit of $1.4 million discretely in the fourth quarter of fiscal 2011.

The effective tax rate of our provision for income taxes differs from the federal statutory rate as follows (in thousands):

Included in the balance of unrecognized tax benefits at January 29, 2011 are $17.6 million of tax benefits that, if recognized, would reduce our effective tax rate.  The remaining amount would be offset by the reversal of related deferred tax assets on which a valuation allowance is placed.  During the twelve months ended January 29, 2011, we added $1.5 million of unrecognized tax benefits.  A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

	Years Ended

Ending Balance		$	20,337			$	18,841			$	10,949

We have adopted the accounting policy that interest and penalty recognized in accordance with ASC 740 are classified as part of our income taxes.  In fiscal 2011, we recorded $0.6 million of such interest and penalty expense and as of January 29, 2011, the balance of such accrued interest and penalty was $0.8 million.

Our operations are subject to income and transaction taxes in the United States and in multiple foreign jurisdictions.  Significant estimates and judgments are required in determining our worldwide provision for income taxes.  Some of these estimates are based on interpretations of existing tax laws or regulations.  The ultimate amount of tax liability may be uncertain as a result.

Our tax filings for the fiscal years from 1996 to 2011 remain open in various taxing jurisdictions.  We do not anticipate that our unrecognized tax benefit would change significantly in the coming 12-month period.

At January 29, 2011, undistributed earnings of our foreign operations totaling $46.5 million were considered to be permanently reinvested.  No deferred tax liability has been recognized for the remittance of such earnings to the U.S. since it is our intention to utilize those earnings in foreign operations.  Generally, such earnings become subject to U.S. tax upon the remittance of dividends and under certain other circumstances.  It is not practicable to estimate the amount of deferred tax liability on such undistributed earnings.

We benefit from tax incentives granted by local tax authorities in certain foreign jurisdictions.  The Economic Development Board of Singapore granted development and expansion incentives to our wholly-owned subsidiary in Singapore in 2008 for a period of four years ending March 1, 2012 contingent on meeting specified requirements.  The Singapore subsidiary can qualify for an additional six years of development and expansion incentives if additional requirements are met.  The impact of this tax holiday was to increase net income by approximately $6.7 million or $0.21 per diluted share in fiscal 2011, $7.0 million or $0.25 per diluted share in fiscal 2010, and $6.5 million or $0.23 per diluted share, in fiscal 2009.

Our acquired Israeli subsidiary CopperGate Communications Ltd. was granted two Approved Enterprise statuses under the Law for the Encouragement of Capital Investments, 1959.  As a result of this grant, CopperGate’s income is tax-exempt for a period of two years commencing with the year it first earns taxable income, and subject to corporate taxes at the reduced rate for an additional period of eight years.  The impact of this tax holiday was to increase net income by approximately $6.2 million, or $0.20 per diluted share, in fiscal 2011.  The impact of this tax holiday was to increase net income by approximately $1.1 million, or $0.04 per diluted share, in fiscal 2010.

18. Related party transactions

During the fourth quarter of fiscal 2009, we liquidated our investment in Envivio, Inc., in which we had invested capital of $0.3 million for an ownership fraction of less than 1% ownership interest.  In addition, three of our board members have liquidated their investments in this same firm, which had aggregated to an ownership fraction of less than 1% ownership interest.  Our Chairman and Chief Executive Officer, Thinh Tran, resigned as a member of Envivio’s Board of Directors.

19. Segment and geographical information

Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and in assessing performance.  We are organized as, and operate in, one reportable segment.  Our operating segment consists of our geographically based entities in the United States, Hong Kong, Israel and Singapore.  Our chief operating decision-maker reviews consolidated financial information, accompanied by information about revenue by product group, target market and geographic region.  We do not assess the performance of our geographic regions on other measures of income or expense, such as depreciation and amortization or net income.

ITEM 9A.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We are committed to maintaining disclosure controls and procedures designed to ensure that information required to be disclosed in our periodic reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and we necessarily are required to apply our judgment in evaluating the cost-benefit relationship of possible controls and procedures and implementing controls and procedures.

As of January 29, 2011, the end of the period covered by this Annual Report on Form 10-K, we have, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of the design and effectiveness of our disclosure controls and procedures, as such terms are defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities and Exchange Act of 1934 as amended (the “Exchange Act”).  Based on this evaluation, we have concluded that our disclosure controls and procedures were effective as of January 29, 2011.

Management’s Report on Internal Control over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act.  Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States.  All internal control systems, no matter how well designed, have inherent limitations.  Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation and may not prevent or detect misstatements.  Projections of any evaluation of effectiveness of internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

76

We, including our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of January 29, 2011.  In making this assessment, we used the criteria set forth in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  Based on this assessment, we concluded that our internal control over financial reporting was effective as of January 29, 2011.

Armanino McKenna LLP, the independent registered public accounting firm that audited our consolidated financial statements included in this Annual Report on Form 10-K, has also assessed the effectiveness of internal control over financial reporting as of January 29, 2011.  Armanino McKenna LLP has issued an attestation report with an unqualified opinion.  This attestation report is included herein under Part II, Item 8.

Changes in Internal Control over Financial Reporting

During the fourth quarter ended January 29, 2011, there were no changes in our internal control over financial reporting (as defined in Rule 13(a) – 15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
