INDUSTRY BACKGROUND

Insatiable consumer demand for anytime, anywhere, always-on wireless connectivity is creating an unprecedented need for high performance analog semiconductor solutions at the wireless access point, within the network cloud and across the supporting infrastructure. This phenomenon has and continues to radically change the way we live, work and play as well as how we communicate. Given that the initial proliferation of these technologies is taking place predominantly in developed countries, we expect further worldwide penetration over the coming years. In fact, according to a June 2012 market research report from Infonetics, the number of global mobile broadband subscribers is expected to grow from 846 million in 2011 to over 2.5 billion subscribers by 2016. In a September 2012 report, the research firm NPD Group said it expects that annual shipments of smartphones, which are at the heart of the mobile Internet, will surpass one billion units by 2016, up from 491 million units in 2011. Similarly, annual shipments of computing tablets, a lower cost alternative to personal computers, are expected to grow significantly, from 73 million units in 2011 as estimated by NPD in a January 2012 report to over 250 million units by 2016. Today's smartphones and tablets can seamlessly take and share pictures, download music, connect to social media networks, provide GPS navigation, stream videos, enable video conferencing, provide voice support services and advice and access a host of Web-based content and applications. This list of ever increasing features and functionalities is delivered in ever thinner platforms with need for extended battery life.

Meanwhile, content providers such as Google Inc., Microsoft Corporation, HBO (a division of Time Warner, Inc.), and Amazon.com, Inc., are building massive libraries of cloud-based, on-demand content. The result is an exploding desire to be connected to the cloud for both entertainment content and personal storage. Supporting cloud-based services requires adding Bluetooth, HSPA, Wi-Fi, GPS and ZigBee® technologies to 2G, 3G and 4G air interface capabilities and embedding them into products ranging from smartphones to tablets, media players and set top boxes.

Table of Contents

All of this activity is stressing traditional infrastructure networks. According to Cisco Systems, Inc.'s 2012 VNI global IP traffic forecast, or the Cisco Report, traffic from wireless networking and mobile access is expected to exceed traffic from wireline devices by 2014, with mobile data expected to increase 18-fold between 2011 and 2016. The significant increase in traffic is being driven by more Internet users and exploding video content. The Cisco Report projects there will be nearly 18.9 billion network connections, almost 2.5 connections for each person on earth, compared to 10.3 billion in 2011 and that by 2016, 1.2 million minutes of video, the equivalent of 833 days, will travel the Internet every second.

High Performance Analog Semiconductors

Outside of the smartphone and tablet markets, wireless technologies are growing across a number of new and exciting vertical applications. The market for analog semiconductors, characterized by longer product lifecycles and relatively high gross margins, is fragmented and diversified spanning a wide variety of end markets including smart energy, power management and machine-to-machine applications, to name just a few.

Smart Energy

Following a decade of promise, smart energy is poised to grow significantly. According to a 2010 study by ABI Research, cumulative global investment in smart grids will exceed $45 billion by 2015, as both governments and utilities repair, upgrade and transform their aging energy supply and transmission infrastructure. Smart grids offer utilities real-time, two-way communications with each segment of the electrical grid, assessing loads, usage, and efficiency twenty-four hours a day. Much of the developed world relies on energy transmission technology and infrastructure that was built between 60 to 80 years ago, and it's beginning to show its age, particularly as consumers experience usage restrictions and brownouts globally. Home and building automation applications in particular are beginning to gain real momentum given consumer demand for green technologies, enhanced security and energy conservation.

Power Management

Power management also provides us with significant growth and diversification opportunities, representing a market potential itself of approximately $2 billion for camera flash drivers and related analog devices in smartphones, as well as products in e-book readers and displays, cable modems and LED lighting. For example, the adoption of cameras in smartphones, along with consumers' expectations for high-quality photographs, is driving accelerated implementation of camera flash drivers in mobile platforms. According to Gartner, Inc., in its September 2011 Market Trends: Digital Camera Function in Mobile and Consumers Electronics report, or the Gartner Camera Report, mobile phone cameras will grow from approximately 1.6 billion units in 2011 to over 2.2 billion units by 2015, penetrating 92 percent of mobile phones worldwide.

Machine to Machine

Beyond connecting places and people, the next phase of the Internet's evolution will be to connect things. Commonly referred to as machine-to-machine connectivity, the internet of things or hyper connectivity, connecting things is based on the simple principle that anything that can be connected to the network will be connected to the network. Smaller, more powerful processors, the growing availability of LTE, higher resolution sensors, and technologies such as thin-film and embedded software are helping make machine- to-machine a reality. In fact, according to an October 2012 Scotiabank report, Ericsson estimates that by 2020 there will be 50 billion machines connected to the Internet, versus an estimated 140 million today. In that same report, Scotiabank estimates that by 2022, there will be 6.1 billion devices with a cellular connection to the network with 2.3 billion added that same year. Scotiabank also believes automotive and medical business sectors will likely be the biggest markets in machine-to-machine connectivity, expected to represent an estimated $1.2 trillion by 2020. For example, while only roughly 5% of cars have mobile communications today, within three to five years, all new cars are expected to have mobile connections. The automobile, in particular, encompasses an array of solutions that connectivity would allow from public safety and reduced fuel consumption to enhanced entertainment features and increased integration into one's smartphone.

Each of these macro trends represents significant growth opportunities for Skyworks given our differentiated product portfolio, scale, original equipment manufacturer relationships and integration skill sets.

SKYWORKS' STRATEGY

Skyworks' overall strategy is to enable mobile connectivity through semiconductor innovation. Key elements in our strategy include:

Table of Contents

Diversifying Our Business

We are diversifying our business in three areas: our addressed markets, our customer base and our product offerings. This multi-level diversification results in stronger and more consistent financial returns. By leveraging our core analog and mixed signal technology, we are able to deliver a growing family of solutions to an expanding set of increasingly diverse end markets and customers. We have steadily grown our business beyond just mobile devices (where we support all top-tier manufacturers including the leading smartphone suppliers and key baseband vendors) into additional high-performance analog markets including infrastructure, smart energy, wireless networking, automotive and medical. In these markets, we take advantage of our scale, intellectual property and worldwide distribution network and invest in our product pipeline so we can expand our addressable markets beyond the over 2,000 customers and over 2,500 analog components currently marketed. We are growing our product portfolio beyond our traditional served markets through a combination of internal developments and targeted acquisitions. This enables us to add incremental addressable content per device to our core available market and generate market traction by cross-selling these products throughout a rapidly expanding customer base.

Leveraging Industry-Leading Technology

As the industry migrates to multimode, multiband EDGE, WEDGE, WCDMA and LTE architectures across a multitude of wireless broadband applications, we are uniquely positioned to help mobile device manufacturers handle growing levels of RF complexity in the transmit and receive chain. The trend towards increasing RF complexity in smartphones and other mobile devices plays directly into Skyworks' core strengths and uniquely positions us to address these challenges. We believe that we offer the broadest portfolio of RF and analog solutions from the transceiver to the antenna as well as all required process technologies. Our expertise includes SOI, high power, GaAs, CMOS, HBT, pHEMT, BiFET and silicon germanium processes. We also hold strong technology leadership positions in passive devices, as well as advanced integration including proprietary shielding and 3-D die stacking. Our product portfolio is reinforced by a library of nearly 1,000 patents and other intellectual property. Together, our industry-leading core competencies enable us to deliver the highest levels of product performance and integration.

Broadening and Deepening Customer Relationships

Given our scale and technology leadership, we are engaged with all handset original equipment manufacturers, smartphone providers and baseband reference design partners. Our customers leverage the strength of our supply chain, our technology and our system engineering expertise in a way that allows us to create a deep customer loyalty. We sit side by side with our customers and focus on meeting their complex RF needs. We partner with our customers to support their long term product road maps and are valued as a system solutions provider rather than just a point product vendor.

Delivering Operational Excellence

We either vertically integrate our supply chain where we can create a competitive advantage, or enter into alliances and strategic relationships for leading-edge capabilities where we do not identify a competitive advantage. This hybrid manufacturing approach allows us to better balance our capacity with the demands of the marketplace. Internally, our capacity utilization remains high and we have therefore been able to maintain margins and been able to achieve our desired return on invested capital on a broader range of revenue.

Additionally, we continue to focus on trying to achieve the industry's shortest product cycle times and highest yields. The combination of agile, flexible capacity combined with world-class module capabilities gives us significant scale, along with a low product cost structure for integrating multiple technologies into highly sophisticated multi-chip modules.

Maintaining a Performance Driven Culture

We consider our people and corporate culture to be a competitive advantage and a key element of our overall strategy. We create key performance indicators that align employee performance with corporate strategy and link responsibilities with performance measurement. Accountability is paramount and we compensate our employees through a pay-for-performance methodology. We strive to be an employer-of-choice among peer companies and have created a work environment in which turnover is well below semiconductor industry averages.

We believe we possess broad technology capabilities and one of the most complete wireless communications product portfolios in the industry.

MARKETING AND DISTRIBUTION

Our products are primarily sold through a direct Skyworks sales force. This team is globally deployed across all of our major market regions. In some markets we supplement our direct sales effort with independent manufacturers' representatives and distribution partners, some of which are franchised globally with others focused in specific regional markets.

Table of Contents

Our sales engagement begins at the earliest stages of the design of an existing or potential customer's product. We strive to provide close technical collaboration with our customers and reference design partners at the inception of new programs. These relationships allow our team to facilitate customer-driven solutions, which leverage the unique strength of our intellectual property and product portfolio while providing high value and greatly reducing time-to-market.

We believe the technical and complex nature of our products and markets demand an extraordinary commitment to maintain close ongoing relationships with our customers. As such, we strive to expand the scope of our customer relationship to include design, engineering, manufacturing, procurement, logistics and project management. We also employ a collaborative approach in developing these relationships by combining the support of our design teams, applications engineers, manufacturing personnel, sales and marketing staff and senior management.

We believe that maintaining frequent and interactive contact with our customers is paramount to our continuous efforts to provide world-class sales and service support. By listening and responding to feedback, we are able to mobilize resources to raise our level of customer satisfaction, improve our ability to anticipate future product needs, and enhance our understanding of key market dynamics. We are confident that diligence in following this path will position Skyworks to participate in numerous opportunities for growth in the future.

CUSTOMER CONCENTRATION

In fiscal year 2012, Foxconn Technology Group ("Foxconn") and Samsung Electronics were our largest customers, each of which accounted for greater than ten percent of our net revenue. For further information regarding concentrations see Note 18 to Item 8 of this Annual Report on Form 10-K.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

We own or have a license to use numerous United States and foreign patents and patent applications related to our products, our manufacturing operations and processes, and our other activities. In addition, we own a number of trademarks and service marks applicable to certain of our products and services. We believe that our intellectual property, including patents, patent applications, trade secrets and trademarks, is of material importance to our business. We rely on patent, copyright, trademark, trade secret and other intellectual property laws, as well as non-disclosure and confidentiality agreements and other methods, to protect our confidential and proprietary technologies, devices, algorithms, processes and other intellectual property. Our efforts may not meaningfully protect our intellectual property, and others may independently develop substantially equivalent or superior proprietary technologies, devices, algorithms, processes or other intellectual property. In addition, the laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and effective copyright, patent, trademark and trade secret protection may not be available in those jurisdictions. In addition to protecting our intellectual property, we strive to strengthen our intellectual property portfolio to enhance our ability to obtain cross-licenses of intellectual property from others, to obtain access to intellectual property we do not possess and to more favorably resolve potential intellectual property claims against us. Furthermore, we seek to generate high gross margin revenue through the sale and license of non-core intellectual property and we occasionally purchase intellectual property. Due to rapid technological changes in the industry, we believe establishing and maintaining a technological leadership position depends primarily on our ability to develop new innovative products through the technical competence of our engineering personnel.

COMPETITIVE CONDITIONS

The competitive environment in the semiconductor industry is in a constant state of flux, with new products continually emerging and existing products approaching technological obsolescence. We compete on the basis of time-to-market, new product innovation, quality, performance, price, compliance with industry standards, strategic relationships with customers and baseband vendors, personnel and protection of our intellectual property. We participate in highly competitive markets against numerous competitors that may be able to adapt more quickly than we can to new or emerging technologies and changes in customer requirements, or may be able to devote greater resources to the development, promotion and sale of their products than we can.

RESEARCH AND DEVELOPMENT

Our products and markets demand rapid technological advancements requiring a continuous effort to enhance existing products and develop new products and technologies. Accordingly, we maintain a high level of research and development activity. We invested $212.5 million , $168.6 million and $134.1 million in research and development activities during the fiscal years ended September 28, 2012 , September 30, 2011 , and October 1, 2010 , respectively. The increase in research and development expense is a result of the additional headcount and development activities associated with the acquisitions of AATI and SiGe, as well as

Table of Contents

increases in our internal product design and development for our target markets. Our research and development activities include new product development and innovations in integrated circuit design, investment in advanced semiconductor manufacturing processes, developing new packaging and test capabilities and researching next generation technologies and product opportunities. We maintain close collaborative relationships with many of our customers to help identify market demands and target our development efforts to meet those demands.

RAW MATERIALS

Raw materials for our products and manufacturing processes are generally available from several sources. It is our policy not to depend on a sole source of supply unless market or other conditions dictate otherwise. Consequently, there are limited situations where we procure certain components and services for our products from single or limited sources. We purchase materials and services primarily pursuant to individual purchase orders. However, we have entered into certain supply agreements for the purchase of raw materials or other manufacturing related services that specify minimum prices and purchase quantity based on our anticipated future requirements. Certain of our suppliers consign raw materials to us at our manufacturing facilities which we take title to as needed in our manufacturing process. We believe we have adequate sources for the supply of raw materials and components for our manufacturing needs with suppliers located around the world.

BACKLOG AND INVENTORY

Our sales are made pursuant to standard purchase orders and/or specified customer contracts for delivery of products, with such purchase orders officially acknowledged by us according to our own terms and conditions. We also maintain Skyworks-owned finished goods inventory at certain customer “hub” locations. We do not recognize revenue until these customers consume the Skyworks-owned inventory from these hub locations. Due to industry practice, which allows customers to cancel orders with limited advance notice to us prior to shipment, and with little or no penalty, we believe that backlog as of any particular date may not be a reliable indicator of our future revenue levels. The cancellation or deferral of product orders, the return of previously sold products, or overproduction due to a change in anticipated order volume could result in a reduction in revenue and us holding excess or obsolete inventory, which could result in inventory write-downs and, in turn, could have a material adverse effect on our financial condition.

ENVIRONMENTAL REGULATIONS

Federal, state and local requirements relating to the discharge of substances into the environment, the disposal of hazardous wastes, and other activities affecting the environment have had, and will continue to have, an impact on our manufacturing operations. Most of our customers have mandated that our products comply with various local, regional and national “green” initiatives initiated by our customers or the locations in which they operate. We believe that our current expenditures for environmental capital investment and remediation necessary to comply with present regulations governing environmental protection, and other expenditures for the resolution of environmental claims, will not have a material adverse effect on our liquidity and capital resources, competitive position or financial condition. Environmental regulations are subject to change in the future, and accordingly we are unable to assess the possible effect of compliance with future requirements.

SEASONALITY

Sales of our products are subject to seasonal fluctuation and periods of increased demand in end-user consumer applications, such as smartphones and tablet computing devices. The highest demand for our products generally occurs in our first fiscal quarter ending in December. The lowest demand for our handset products generally occurs in our second fiscal quarter.

GEOGRAPHIC INFORMATION

For information regarding net revenue by geographic region for each of the last three fiscal years, see Note 18 of Item 8 of this Annual Report on Form 10-K.

EMPLOYEES

As of September 28, 2012 , we employed approximately 4,700 employees world-wide (as compared to 4,400 as of September 30, 2011). Approximately 550 of our employees in Mexico are covered by collective bargaining agreements.

ITEM 1A. RISK FACTORS.

You should carefully consider the risks described below in addition to the other information contained in this report before making an investment decision with respect to any of our securities. Our business, financial condition or results of operations could be harmed by any of these risks. The risks and uncertainties described below are not the only ones we face. Additional risks not currently known to us or other factors not perceived by us present significant risks to our business at this time also may impair our business operations, financial condition or results from operations.

We operate in the highly cyclical semiconductor industry, which is subject to significant downturns.

We operate in the semiconductor industry, which is cyclical and subject to rapid declines in demand for end-user products in both the consumer and enterprise markets. Continued uncertain economic conditions worldwide, together with other factors such as the volatility of the financial markets, continue to make it difficult for our customers and for us to accurately forecast and plan future business activities. Although we believe that the market for our semiconductor products has stabilized to some extent, continued uncertainty and economic weakness could result in a market contraction and, as a result, our business, financial condition and results of operations would likely be materially and adversely affected. Such periods of industry downturn are characterized by diminished product demand and revenue, manufacturing overcapacity, excess inventory levels, accelerated erosion of average selling prices, and restructuring and/or impairment charges. Furthermore, downturns in the semiconductor industry may be prolonged, and any extended delay or failure of the market to recover from an economic downturn would materially and adversely affect our business, financial condition and results of operations beyond our current fiscal year.

Our operating results may be adversely affected by quarterly and annual fluctuations and market downturns.

Our revenues, earnings and other operating results may fluctuate significantly on a quarterly and annual basis. These fluctuations are typically the result of a number of factors, many of which are beyond our control.

These factors include, among others:


•	changes in end-user demand for the products (principally smartphones) manufactured and sold by our customers,


•	the effects of competitive pricing pressures, including decreases in average selling prices of our products,


•	production capacity levels and fluctuations in manufacturing yields,


•	availability and cost of materials and services from our suppliers,


•	the gain or loss of significant customers,


•	our ability to develop, introduce and market new products and technologies on a timely basis,


•	new product and technology introductions by competitors,


•	changes in the mix of products produced and sold,


•	market acceptance of our products and our customers,


•	our ability to continue to generate revenues by licensing and/or selling non-core intellectual property, and


•	intellectual property disputes, including those concerning payments associated with the licensing and/or sale of intellectual property.

The foregoing factors are difficult to forecast, and these, as well as other factors, could materially and adversely affect our quarterly or annual operating results. If our operating results fail to meet the expectations of analysts or investors, it could materially and adversely affect the price of our common stock.

Our stock price has been volatile and may fluctuate in the future.

The trading price of our common stock has and may continue to fluctuate significantly. Such fluctuations may be influenced by many

Table of Contents

factors, including:


•	the volatility of the financial markets,


•	uncertainty regarding the prospects of the domestic and foreign economies,


•	our performance and prospects,


•	the performance and prospects of our major customers,


•	the depth and liquidity of the market for our common stock,


•	investor perception of us and the industry in which we operate,


•	changes in earnings estimates, price targets or buy/sell recommendations by analysts,


•	domestic and international political conditions,


•	domestic and international tax and fiscal policy decisions (including the possibility of expiring tax cuts combined with mandatory reductions in federal spending in the United States), and


•	the ability to successfully identify, acquire and integrate acquisition candidates.

Public stock markets have experienced price and trading volume volatility. This volatility has and continues to significantly and negatively affect the market prices of securities of many technology companies, including the market price of our common stock. Such volatility could materially and adversely affect the market price of our common stock in future periods.

In addition, fluctuations in our stock price, volume of shares traded, and changes in our trading multiples may make our stock attractive to momentum, hedge or day-trading investors who often shift funds into and out of stocks rapidly, exacerbating price fluctuations in either direction. Our company has been, and in the future may be, the subject of commentary by financial news media. Such commentary may contribute to volatility in our stock price. If our operating results do not meet the expectations of securities analysts, the financial news media or investors, our stock price may decline, possibly substantially over a short period of time.

The wireless communications and analog semiconductor markets are characterized by significant competition which may cause pricing pressures, decreased gross margins and rapid loss of market share and may materially and adversely affect our business, financial condition and results of operations.

The wireless communications semiconductor industry in general and the other analog markets in which we compete in particular are very competitive. We compete with United States and international semiconductor manufacturers of all sizes in terms of resources and market share, including Analog Devices, Avago Technologies, Hittite Microwave, Linear Technologies, Maxim Integrated Products, Peregrine Semiconductor, RF Micro Devices, and Triquint Semiconductor.

We currently face significant competition in our markets and expect that intense price and product competition will continue. This competition has resulted in, and is expected to continue to result in, declining average selling prices for our products and increased challenges in maintaining or increasing gross margin and market share. Furthermore, additional competitors may enter our markets as a result of growth opportunities in communications electronics, the trend toward global expansion by foreign and domestic competitors and technological and public policy changes. We believe that the principal competitive factors for semiconductor suppliers in our markets include, among others:


•	rapid time-to-market and product ramp,


•	timely new product innovation,


•	product quality, reliability and performance,


•	product price,


•	features available in products,

Table of Contents


•	alignment with customer performance specifications,


•	compliance with industry standards,


•	strategic relationships with customers,


•	access to and protection of intellectual property,


•	ability to partner with/ participate in reference designs of baseband vendors, and


•	maintaining access to manufacturing capacity, raw materials, supplies and services at a competitive cost.

We might not be able to successfully address these factors. Many of our competitors enjoy the benefit of:


•	long presence in key markets,


•	brand recognition,


•	high levels of customer satisfaction,


•	strong baseband partnership/ participation in reference designs,


•	a broad product portfolio allowing them to bundle product offerings,


•	ownership or control of key technology or intellectual property, and


•	strong financial, sales and marketing, manufacturing, distribution, technical or other resources.

As a result, certain competitors may be able to adapt more quickly than we can to new or emerging technologies and changes in customer requirements or may be able to devote greater resources to the development, promotion and sale of their products than we can.

Current and potential competitors have established, or may in the future establish, financial or strategic relationships among themselves or with customers, resellers or other third parties. These relationships may affect customers' purchasing decisions. Accordingly, it is possible that new competitors or alliances among competitors could emerge and rapidly acquire significant market share. We may not be able to compete successfully against current and potential competitors. Increased competition could result in pricing pressures, decreased gross margins and loss of market share and may materially and adversely affect our business, financial condition and results of operations.

Our success depends upon our ability to develop new products and reduce costs in a timely manner.

The semiconductor industry generally and, in particular, many of the markets into which we sell our products are highly cyclical and characterized by constant and rapid technological change, continuous product evolution, price erosion, evolving technical standards, short product life cycles, increasing demand for higher levels of integration, increased miniaturization, reduced power consumption and wide fluctuations in product supply and demand. Our operating results depend largely on our ability to continue to cost-effectively introduce new and enhanced products on a timely basis. The successful development and commercialization of semiconductor devices and modules is highly complex and depends on numerous factors, including the ability:


•	to anticipate customer and market requirements and changes in technology and industry standards,


•	to obtain sufficient manufacturing capacity to meet customer demand,


•	to define new products that meet customer and market requirements,


•	to complete development of new products and bring products to market on a timely basis,


•	to differentiate our products from offerings of our competitors,

Table of Contents


•	for overall market acceptance of our products,


•	to lengthen the time that a particular product is in demand, and


•	to obtain adequate intellectual property protection for our new products.

Our ability to manufacture current products, and to develop new products, depends on, among other factors, the viability and flexibility of our own internal information technology systems.

We continually evaluate expenditures for planned product development and to choose among alternative technologies based on our understanding of customer technical requirements, new industry standards and expectations of future market growth. We may not be able to develop and introduce new or enhanced wireless communications semiconductor products in a timely and cost-effective manner, and our products may not satisfy customer requirements or achieve market acceptance or we may not be able to anticipate new industry standards and technological changes. We also may not be able to respond successfully to new product announcements and introductions by competitors or to changes in the design or specifications of complementary products of third parties with which our products interface. If we fail to rapidly and cost-effectively introduce new and enhanced products in sufficient quantities that meet our customers' requirements, our business and results of operations would be materially and adversely harmed.

In addition, prices of many of our products decline, sometimes significantly, over time. Our products may become obsolete earlier than planned or may not have life cycles long enough to allow us to recoup the cost of our investment in designing such products. Accordingly, we believe that to remain competitive, we must continue to reduce the cost of producing and delivering existing products at the same time that we develop and introduce new or enhanced products. We may not be able to continue to reduce the cost of producing and delivering our products and thereby remain competitive.

If Original Equipment Manufacturers, or OEMs, and Original Design Manufacturers, or ODMs, of communications electronics products do not design our products into their equipment, we will have difficulty selling those products. Moreover, a “design win” from a customer does not guarantee future sales to that customer.

Our products are not sold directly to the end-user, but are components or subsystems of other products. As a result, we rely on OEMs and ODMs of wireless communications electronics products to select our products from among alternative offerings to be designed into their equipment. Without these “design wins,” we would have difficulty selling our products. If a manufacturer designs another supplier's product into one of its product platforms, it is more difficult for us to achieve future design wins with that platform because changing suppliers involves significant cost, time, effort and risk on the part of that manufacturer. Also, achieving a design win with a customer does not ensure that we will receive significant revenue from that customer. Even after a design win, the customer is not obligated to purchase our products and can choose at any time to reduce or cease use of our products, for example, if its own products are not commercially successful, or for any other reason. We may not continue to achieve design wins or to convert design wins into actual sales, and failure to do so could materially and adversely affect our operating results.

Our manufacturing processes are extremely complex and specialized and disruptions could have a material adverse effect on our business, financial condition and results of operations.

Our manufacturing operations are complex and subject to disruption, including due to causes beyond our control. The fabrication of integrated circuits is an extremely complex and precise process consisting of hundreds of separate steps. It requires production in a highly controlled, clean environment. Minor impurities, contamination of the clean room environment in which our products are produced, errors in any step of the fabrication process, defects in the masks used to print circuits on a wafer, defects in equipment or materials, human error, or a number of other factors can cause a substantial percentage of our products to be rejected or to malfunction. Because our operating results are highly dependent upon our ability to produce integrated circuits at acceptable manufacturing yields, these factors could have a material and adverse effect on our business.

Additionally, our operations may be affected by lengthy or recurring disruptions of operations at any of our production facilities, as well as disruptions at facilities operated by our subcontractors and customers. These disruptions may result from electrical power outages, fire, earthquake, flooding, war, acts of terrorism, health advisories or risks, or other natural or manmade disasters, as well as equipment maintenance, repairs and/or upgrades. Disruptions of our manufacturing operations, or those of our subcontractors and customers, could cause significant delays in shipments until we are able to shift production of the impacted products from an affected facility or subcontractor to another facility or subcontractor, or until the affected customer resumes operations and accepts shipments from us. In the event of such delays, the required alternative capacity, particularly wafer production capacity, may not be available on a timely basis or at all. Even if alternative production capacity is available, we may not be able to obtain it on favorable terms,

Table of Contents

which could result in higher costs and/or a loss of customers and revenue.

Due to the highly specialized nature of the gallium arsenide integrated circuit manufacturing process, in the event of a disruption in production at our Newbury Park, California or Woburn, Massachusetts semiconductor wafer fabrication facilities as well as our assembly and test facility in Mexicali Mexico for any reason, alternative gallium arsenide production capacity would not be immediately available from third-party sources. These disruptions could have a material adverse effect on our business, financial condition and results of operations.

We may be subject to warranty claims, product recalls and liability claims.

Although we invest significant resources in the testing of our products, we may discover from time to time defects in our products after they have been shipped, and we may be required to incur additional development and remediation costs, or cash payments to settle claims pursuant to warranty and indemnification provisions in our customer contracts and purchase orders. The potential liabilities associated with these, and similar, provisions in certain of our customer contracts are capped at significant amounts, or are uncapped. These problems may divert our technical and other resources from other product development efforts and could result in claims against us by our customers or others, including liability for costs associated with product recalls, or other obligations under customer contracts. If any of our products contain defects, or have reliability, quality or compatibility problems, our reputation may be damaged and we could be subject to liability claims, which could make it more difficult for us to sell our products to existing and prospective customers and could adversely affect our operating results.

We may not be able to maintain and improve manufacturing yields that contribute positively to our gross margin and profitability.

Minor deviations or disturbances in the manufacturing process can cause substantial manufacturing yield loss, and in some cases, cause production to be suspended and impact our ability to meet customer demand on a timely basis. Manufacturing yields for new products initially tend to be lower as we complete product development and commence volume manufacturing, and typically increase as we bring the product to full production. Our forward product pricing includes this assumption of improving manufacturing yields and, as a result, material variances between projected and actual manufacturing yields will have a direct effect on our gross margin and profitability. The difficulty of accurately forecasting manufacturing yields and maintaining cost competitiveness through improving manufacturing yields will continue to be magnified by the increasing process complexity of manufacturing semiconductor products. Our manufacturing operations may also face pressures arising from the compression of product life cycles, which may require us to manufacture new products faster and for shorter periods while maintaining acceptable manufacturing yields and quality without, in many cases, reaching the longer-term, high-volume manufacturing conducive to higher manufacturing yields and declining costs.

We are dependent upon third parties for the manufacture, assembly and testing of our products.

We rely upon independent wafer fabrication facilities, called foundries, to provide silicon-based products and to supplement our gallium arsenide wafer manufacturing capacity. There are significant risks associated with reliance on third-party foundries, including:


•	the lack of wafer supply, potential wafer shortages and higher wafer prices,


•	limited ability to respond to unanticipated changes in customer demand,


•	limited control over delivery schedules, manufacturing yields, production costs and quality assurance, and


•	the inaccessibility of, or delays in, obtaining access to, key process technologies.

Although we have long-term supply arrangements to obtain additional external manufacturing capacity, the third-party foundries we use for our standby manufacturing capacity may allocate their limited capacity to the production requirements of other customers and we have no contractual right to prevent them from making such allocations. If we choose to use a new foundry to replace either existing or backup capacity, it will typically take an extended period of time for us to complete our qualification process for that foundry which will result in a significant passage of time before we can begin shipping products from that new foundry.

Further, the third-party foundries may experience financial difficulties, be unable to deliver products to us in a timely manner or suffer damage or destruction to their facilities, particularly since some of them are located in areas prone to natural disasters. If any disruption of manufacturing capacity occurs, we may not have alternative manufacturing sources immediately available. We may therefore experience difficulties or delays in securing an adequate supply of our products, which could impair our ability to meet our customers' needs and have a material adverse effect on our operating results.

Table of Contents

Although we own and operate an assembly and test facility, we still depend on subcontractors to package, assemble and test certain of our products at cost-competitive rates. We do not have long-term agreements with any of our assembly or test subcontractors and typically procure services from these suppliers on a per order basis. If any of these subcontractors experiences capacity constraints or financial difficulties, suffers any damage to its facilities, experiences power outages or any other disruption of assembly or testing capacity, we may not be able to obtain alternative assembly and testing services in a timely manner and/or at cost-competitive rates. Due to the amount of time that it usually takes us to qualify assemblers and testers, we could experience significant delays in product shipments if we are required to find alternative assemblers or testers for our components. Any problems that we may encounter with the delivery, quality or cost of our products could damage our customer relationships and materially and adversely affect our results of operations.

We are dependent upon third parties for the supply of raw materials and components.

Our manufacturing operations depend on obtaining adequate supplies of raw materials and components used in our manufacturing processes at a competitive cost. Although we maintain relationships with suppliers located around the world with the objective of ensuring that we have adequate sources for the supply of raw materials and components for our manufacturing needs, increases in demand from the semiconductor industry for such raw materials and components, as well as increased demand for commodities in general, can result in tighter supplies and higher costs. Our suppliers may not be able to meet our delivery schedules, we may lose a significant or sole supplier, a supplier may not be able to meet performance and quality specifications and we may not be able to purchase such supplies or material at a competitive cost. If a supplier were unable to meet our delivery schedules or if we lost a supplier or a supplier were unable to meet performance or quality specifications, our ability to satisfy customer obligations would be materially and adversely affected. In addition, we review our relationships with suppliers of raw materials and components for our manufacturing needs on an ongoing basis. In connection with our ongoing review, we may modify or terminate our relationship with one or more suppliers. We may also enter into sole supplier arrangements to meet certain of our raw material or component needs. While we do not typically rely on a single source of supply for our raw materials, we are currently dependent on a limited number of sole-source suppliers. If we were to lose these sole sources of supply, for any reason, a material adverse effect on our business could result until an alternate source is obtained. To the extent we enter into additional sole supplier arrangements for any of our raw materials or components, the risks associated with our supply arrangements would be exacerbated.

Our reliance on a small number of customers for a large portion of our sales could have a material adverse effect on the results of our operations.

Significant portions of our sales are concentrated among a limited number of customers. If we lost one or more of these major customers, or if one or more major customers significantly decreased its orders for our products, our business could be materially and adversely affected. In fiscal year 2012 two customers, Foxconn and Samsung Electronics each accounted for greater than ten percent of our net revenue. For further discussion see Note 18 to Item 8 of this Annual Report on Form 10-K.

If we are unable to attract and retain qualified personnel to contribute to the design, development, manufacture and sale of our products, we may not be able to effectively operate our business.

As the source of our technological and product innovations, our key technical personnel represent a significant asset. Our success depends on our ability to continue to attract, retain and motivate qualified personnel, including executive officers and other key management and technical personnel. The competition for management and technical personnel is intense in the semiconductor industry, and therefore we may not be able to continue to attract and retain the qualified management and other personnel necessary for the design, development, manufacture and sale of our products. We may have particular difficulty attracting and retaining key personnel during periods of poor operating performance and/or declines in the price of our common stock, given among other things, the use of equity-based compensation by us and our competitors. The loss of the services of one or more of our key employees or our inability to attract, retain and motivate qualified personnel, could have a material adverse effect on our ability to operate our business.

Our business would be adversely affected by the departure of existing members of our senior management team or if our senior management team is unable to effectively implement our strategy.

Our success depends, in large part, on the continued contributions of our senior management team, none of whom is bound by a written employment contract to remain with us for a specified period. The loss of any of our senior management could harm our ability to implement our business strategy and respond to the rapidly changing market conditions in which we operate.

Lengthy product development and sales cycles associated with many of our products may result in significant expenditures before

Table of Contents

generating any revenues related to those products.

After one of our products has been developed, tested and manufactured, our customers may need three to six months or longer to integrate, test and evaluate that product and an additional three to six months or more to begin volume production of equipment that incorporates the product. This lengthy cycle time increases the possibility that a customer may decide to cancel or change product plans, which could reduce or eliminate our sales to that customer. As a result of this lengthy sales cycle, we may incur significant research and development expenses, and selling, general and administrative expenses, before we generate the related revenue for these products. Furthermore, we may never generate the anticipated revenues from a product after incurring such expenses if our customer cancels or changes its product plans.

Uncertainties involving the ordering and shipment of, and payment for, our products could adversely affect our business.

Our sales are made pursuant to individual purchase orders, master service agreements, etc. and not under long-term supply arrangements with our customers. Our customers may cancel orders before shipment. Additionally, we sell a portion of our products through distributors, some of whom have rights to return unsold products if the product is defective. We may purchase and manufacture inventory based on estimates of customer demand for our products, which is difficult to predict. This difficulty may be compounded when we sell to OEMs indirectly through distributors or contract manufacturers, or both, as our forecasts of demand will then be based on estimates provided by multiple parties. In addition, our customers may change their inventory practices on short notice for any reason. The cancellation or deferral of product orders, the return of previously sold products, or overproduction due to a change in anticipated order volumes could result in us holding excess or obsolete inventory, which could result in inventory write-downs and, in turn, could have a material adverse effect on our financial condition.

In addition, if a customer encounters financial difficulties of its own as a result of a change in demand or for any other reason, the customer's ability to make timely payments to us for non-returnable products could be impaired.

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

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark and other intellectual property rights to technologies that are important to our business and have demanded and may in the future demand that we license their technology or refrain from using it.

Any litigation to determine the validity of claims that our products infringe or may infringe intellectual property rights of another, including claims arising from our contractual indemnification of our customers, regardless of their merit or resolution, could be costly and divert the efforts and attention of our management and technical personnel. Regardless of the merits of any specific claim, we may not prevail in litigation because of the complex technical issues and inherent uncertainties in intellectual property litigation. If litigation were to result in an adverse ruling, we could be required to:


•	pay substantial damages,


•	cease the manufacture, import, use, sale or offer for sale of infringing products or processes,


•	discontinue the use of infringing technology,


•	expend significant resources to develop non-infringing technology, and


•	license technology from the third party claiming infringement, which license may not be available on commercially reasonable terms.

Our operating results or financial condition may be materially adversely affected if we, or one of our customers, were required to take any one or more of the foregoing actions.

In addition, if another supplier to one of our customers, or a customer of ours itself, were found to be infringing upon the intellectual property rights of a third party, the supplier or customer could be ordered to cease the manufacture, import, use, sale or offer for sale of its infringing product(s) or process(es), either of which could result, indirectly, in a decrease in demand from our customers for our products. If such a decrease in demand for our products were to occur, it could have an adverse impact on our operating results.

Many of our products currently incorporate technology licensed or acquired from third parties and we expect our products in the future to also require technology from third parties. If the licenses to such technology that we currently hold become unavailable or the terms on which they are available become commercially unreasonable, or if we are unable to acquire or license necessary technology for our products in the future, our business could be adversely affected.

We sell products in markets that are characterized by rapid technological changes, evolving industry standards, frequent new product introductions, short product life cycles and increasing levels of integration. Our ability to keep pace with this market depends on our ability to obtain technology from third parties on commercially reasonable terms to allow our products to remain competitive. If licenses to such technology are not available on commercially reasonable terms and conditions or at all, and we cannot otherwise acquire or integrate such technology, our products or our customers' products could become unmarketable or obsolete, and we could lose market share. In such instances, we could also incur substantial unanticipated costs or scheduling delays to develop substitute technology to deliver competitive products.

If we are not successful in protecting our intellectual property rights, our ability to compete successfully may be materially and adversely affected.

We rely on patent, copyright, trademark, trade secret and other intellectual property laws, as well as nondisclosure and confidentiality agreements and other methods, to protect our proprietary technologies, information, data, devices, algorithms, processes and other intellectual property. In addition, we often incorporate the intellectual property of our customers, suppliers or other third parties into our designs, and we have obligations with respect to the non-use and non-disclosure of such third-party intellectual property. In the future, it may be necessary to engage in litigation or like activities to enforce our intellectual property rights, to protect our trade secrets or to determine the validity and scope of proprietary rights of others, including our customers. This could require us to expend significant resources and to divert the efforts and attention of our management and technical personnel from our business operations. Regardless of our actions:


•	the steps we take to prevent misappropriation, infringement, dilution or other violation of our intellectual property or the intellectual property of our customers, suppliers or other third parties may not be successful, and


•	any of our existing or future patents, copyrights, trademarks, trade secrets or other intellectual property rights may be challenged, invalidated or circumvented.

Despite these precautions, it may be possible for a third party to copy or otherwise obtain and use our technology without authorization, develop similar technology independently or design around our patents. If any of our intellectual property protection mechanisms fails to protect our technology, it would make it easier for our competitors to offer similar products, potentially resulting in loss of market share and price erosion. Even if we receive a patent, the patent claims may not be broad enough to adequately protect our technology. Furthermore, even if we receive patent protection in the United States, we may not seek, or may not be granted, patent protection in foreign countries. In addition, effective patent, copyright, trademark and trade secret protection may be unavailable or limited for certain technologies and in certain foreign countries.

We attempt to control access to and distribution of our proprietary information through operational, technological and legal safeguards. Despite our efforts, parties, including former or current employees, may attempt to copy, disclose or obtain access to our information without our authorization. Furthermore, attempts by computer hackers to gain unauthorized access to our systems or information could result in our proprietary information being compromised or interrupt our operations. While we attempt to prevent such unauthorized access we may be unable to anticipate the methods used, or be unable to prevent the release of our proprietary information.

We are subject to the risks of doing business internationally.

A substantial majority of our net revenue is derived from customers located outside the United States, primarily in countries located in the Asia-Pacific region and Europe. In addition, we have suppliers located outside the United States, and third-party packaging, assembly and test facilities and foundries located in the Asia-Pacific region. Finally, we have our own packaging, assembly and test facility in Mexicali, Mexico. Our international sales and operations are subject to a number of risks inherent in selling and operating abroad. These include, but are not limited to, risks regarding:


•	currency exchange rate fluctuations, including changes in commodities prices related to such fluctuations,


•	local economic and political conditions, including social, economic and political instability,


•	labor market conditions and worker's rights,

Table of Contents


•	disruptions of capital and trading markets,


•	inability to collect accounts receivable,


•	restrictive governmental actions (such as restrictions on transfer of funds and trade protection measures, including export duties, quotas, customs duties, increased import or export controls and tariffs),


•	changes in, or non-compliance with, legal or regulatory import/export requirements,


•	natural disasters, acts of terrorism, widespread illness and war,


•	limitations on the repatriation of funds,


•	difficulty in obtaining distribution and support,


•	cultural differences in the conduct of business,


•	direct or indirect government actions or policies aimed at supporting local industry,


•	the laws and policies of the United States and other countries affecting trade, foreign investment and loans, and import or export licensing requirements,


•	changes in current or future tax law or regulations or new interpretations thereof, by federal or state agencies or foreign governments could adversely affect our results of operations,


•	changes in the effective tax rate as a result of our overall profitability and mix of earnings in countries with differing statutory tax rates


•	results of audits and examination of previously filed tax returns,


•	the possibility of being exposed to legal proceedings in a foreign jurisdiction,


•	limitations on our ability under local laws to protect or enforce our intellectual property rights in a particular foreign jurisdiction, and


•	restrictions on our ability to repatriate foreign earnings or unfavorable tax impactions related to the same.

Additionally, we are subject to risks in certain global markets in which wireless operators provide subsidies on handset sales to their customers. Increases in cellular handset prices that negatively impact handset sales can result from changes in regulatory policies or other factors, which could impact the demand for our products. Limitations or changes in policy on phone subsidies in South Korea, Japan, China and other countries may have additional negative impacts on our revenues.

We are particularly exposed to risks of doing business in China. We expect to continue to expand our business and operations in China. Our success in the Chinese markets may be adversely affected by China's continuously evolving laws and regulations, including those relating to taxation, import and export tariffs, currency controls, environmental regulations, indigenous innovation, and intellectual property rights and enforcement of those rights. Enforcement of existing laws or agreements may be inconsistent. In addition, changes in the political environment, governmental policies or U.S.-China relations could result in revisions to laws or regulations or their interpretation and enforcement, exposure of our proprietary intellectual property, increased taxation, restrictions on imports, import duties or currency revaluations, which could have an adverse effect on our business plans and operating results. Further, the evolving labor market and increasing labor unrest in China may have a negative impact on our customers which would result in a negative impact on our business and results of operations.

We face a risk that capital needed for our business will not be available when we need it.

To the extent that our existing cash and cash equivalents and cash generated from operations are insufficient to fund our future activities or repay future debt when it becomes due, we may need to raise additional funds through public or private equity or debt financing. If unfavorable capital market conditions exist if and when we were to seek additional financing, we may not be able to raise sufficient capital on favorable terms and on a timely basis (if at all). Failure to obtain capital when required by our business

Table of Contents

circumstances would have a material adverse effect on us.

In addition, any strategic investments and acquisitions that we may make to help us grow our business may require additional capital resources. The capital required to fund these investments and acquisitions may not be available in the future.

Remaining competitive in the semiconductor industry requires transitioning to smaller geometry process technologies and achieving higher levels of design integration.

In order to remain competitive, we expect to continue to transition our products to increasingly smaller geometries. This transition requires us to modify the manufacturing processes for our products, design new products to more stringent standards, and to redesign some existing products. In the past, we have experienced some difficulties migrating to smaller geometry process technologies or new manufacturing processes, which resulted in sub-optimal 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 in the future. In some instances, we depend on our relationships with our third-party foundries to transition to smaller geometry processes successfully. Our foundries may not be able to effectively manage the transition or we may not be able to maintain our foundry relationships. If our foundries or we experience significant delays in this transition or fail to efficiently implement this transition, our business, financial condition and results of operations could be materially and adversely affected. As smaller geometry processes become more prevalent, we expect to continue to integrate greater levels of functionality, as well as customer and third party intellectual property, into our products. However, we may not be able to achieve higher levels of design integration or deliver new integrated products on a timely basis, or at all.

Increasingly stringent environmental laws, rules and regulations may require us to redesign our existing products and processes, and could adversely affect our ability to cost-effectively produce our products.

The semiconductor industry has been subject to increasing environmental regulations, particularly those environmental requirements that control and restrict the use, transportation, emission, discharge, storage and disposal of certain chemicals, elements and materials used or produced in the semiconductor manufacturing process. Heightened public focus on sustainability and environmental issues has also led to increased government regulation and caused certain of our customers to impose environmental standards on us as a part of doing business with them. We expect that the trend of increasing environmental awareness will continue for the foreseeable future which will result in higher costs of operations. In addition, our commitment to environmentally sustainable practices, while undertaken in a manner designed to be as efficient and cost effective as possible, may result increases in costs of operations for us relative to our competitors until technologies and methods are developed that will help reduce those costs or such practices become industry best practice.

A number of domestic and foreign jurisdictions seek to restrict the use of various substances, a number of which have been or are currently used in our products or processes. For example, the European Union Restriction of Hazardous Substances in Electrical and Electronic Equipment ("RoHS") Directive now requires that certain substances, which may be found in certain products we have manufactured in the past, be removed from all electronics components. Eliminating such substances from our manufacturing processes requires the expenditure of additional research and development funds to seek alternative substances for our products, as well as increased testing by third parties to ensure the quality of our products and compliance with the RoHS Directive. While we have implemented a compliance program to ensure our product offering meets these regulations, there may be instances where alternative substances will not be available or commercially feasible, or may only be available from a single source, or may be significantly more expensive than their restricted counterparts. Additionally, if we were found to be non-compliant with any such rule or regulation, we could be subject to fines, penalties and/or restrictions imposed by government agencies that could adversely affect our operating results.

The SEC recently adopted disclosure rules for companies that use conflict minerals in their products, with substantial supply chain verification requirements in the event that the materials come from, or could have come from, the Democratic Republic of the Congo or adjoining countries. These new rules and verification requirements, which will apply to our activities in calendar 2013, will impose additional costs on us and on our suppliers, and may limit the sources or increase the prices of materials used in our products. Further, if we are unable to certify that our products are conflict free, we may face challenges with our customers, which could place us at a competitive disadvantage, and our reputation may be harmed.

New climate change laws and regulations could require us to change our manufacturing processes or obtain substitute materials that may cost more or be less available for our manufacturing operations. In addition, new restrictions on emissions of carbon dioxide or other greenhouse gases could result in significant costs for us. The Commonwealth of Massachusetts has adopted greenhouse gas regulations, and the U.S. Congress may pass federal greenhouse gas legislation in the future. The U.S. Environmental Protection

Table of Contents

Agency (“EPA”) has issued greenhouse gas reporting regulations that may apply to certain of our operations. The EPA is developing other climate change-based regulations, as are certain states, that also may increase our expenses and adversely affect our operating results. We expect increased worldwide regulatory activity relating to climate change in the future. Compliance with these laws and regulations has not had a material impact on our capital expenditures, earnings, financial condition or competitive position.

We may be liable for penalties under environmental laws, rules and regulations, which could adversely impact our business.

We have used, and will continue to use, a variety of chemicals and compounds in manufacturing operations and have been and will continue to be subject to a wide range of environmental protection regulations in the United States and in foreign countries. Current or future regulation of the materials necessary for our products may have a material adverse effect on our business, financial condition and results of operations. Environmental regulations often require parties to fund remedial action for violations of such regulations regardless of fault. Consequently, it is often difficult to estimate the future impact of environmental matters, including potential liabilities. Furthermore, our customers increasingly require warranties or indemnity relating to compliance with environmental regulations. The amount of expense and capital expenditures that might be required to satisfy environmental liabilities, to complete remedial actions and to continue to comply with applicable environmental laws may have a material adverse effect on our business, financial condition and results of operations.

If wireless devices pose safety risks, we may be subject to new regulations, and demand for our solutions and those of our licensees and customers may decrease.

Concerns over the effects of radio frequency emissions, even if unfounded, may have the effect of discouraging the use of wireless devices, which may decrease demand for our solutions and those of our licensees and customers. In recent years, the Federal Communications Committee ("FCC") and foreign regulatory agencies have updated the guidelines and methods they use for evaluating radio frequency emissions from radio equipment, including wireless phones and other wireless devices. In addition, interest groups have requested that the FCC investigate claims that wireless communications technologies pose health concerns and cause interference with airbags, hearing aids and medical devices. Concerns have also been expressed over the possibility of safety risks due to a lack of attention associated with the use of wireless devices while driving. Any legislation that may be adopted in response to these expressions of concern could reduce demand for wireless communications devices that contain our products.

Our gallium arsenide semiconductors may cease to be competitive with silicon alternatives.

Among our product portfolio, we manufacture and sell gallium arsenide semiconductor devices and components, principally power amplifiers and switches. The production of gallium arsenide integrated circuits is more costly than the production of silicon circuits. The cost differential is due to higher costs of raw materials for gallium arsenide and higher unit costs associated with smaller sized wafers and lower production volumes. Further, silicon based designs offer alternatives within the system architecture which are unavailable for gallium arsenide based designs. Therefore, to remain competitive, we must offer gallium arsenide products that provide superior performance over their silicon-based counterparts. Although we manufacture and sell silicon-based power amplifiers, if we do not continue to offer gallium arsenide products that provide sufficiently superior performance to justify the cost differential, our operating results may be materially and adversely affected. We expect the costs of producing gallium arsenide devices will continue to exceed the costs of producing their silicon counterparts. Silicon semiconductor technologies are widely used process technologies for certain integrated circuits and these technologies continue to improve in performance. We may not continue to identify products and markets that require performance attributes of gallium arsenide products.

To be successful we may need to make certain investments and acquisitions, integrate companies we acquire, and/or enter into strategic alliances.

Although we have invested in the past, and intend to continue to invest, significant resources in internal research and development activities, the complexity and rapidity of technological changes and the significant expense of internal research and development make it impractical for us to pursue development of all technological solutions on our own. On an ongoing basis, we review investment, alliance and acquisition prospects that would complement our product offerings, augment our market coverage or enhance our technological capabilities. We may not be able to identify and consummate suitable investment, alliance or acquisition transactions in the future. Moreover, if such transactions are consummated, they could result in:


•	issuances of equity securities dilutive to our stockholders,


•	large, transactions, restructuring or other impairment write-offs,

Table of Contents


•	the incurrence of substantial debt and assumption of unknown liabilities,


•	the potential loss of key employees from the acquired company,


•	recognition of additional liabilities known or unknown at the time of acquisition,


•	amortization expenses related to intangible assets, and


•	the diversion of management's attention from other business concerns.

Moreover, integrating acquired organizations and their products and services may be difficult, expensive, time-consuming and a strain on our resources and our relationship with employees and customers and ultimately may not be successful. Additionally, in periods following an acquisition, we will be required to evaluate goodwill and acquisition-related intangible assets for impairment. If such assets are found to be impaired, they will be written down to estimated fair value, with a charge against earnings.

Certain provisions in our organizational documents and Delaware law may make it difficult for someone to acquire control of us.

We have certain anti-takeover measures that may affect our common stock. Our certificate of incorporation, our by-laws and the Delaware General Corporation Law contain several provisions that would make more difficult an acquisition of control of us in a transaction not approved by our Board of Directors. Our certificate of incorporation and by-laws include provisions such as:


•	the ability of our Board of Directors to issue shares of preferred stock in one or more series without further authorization of stockholders,


•	a prohibition on stockholder action by written consent,


•	elimination of the right of stockholders to call a special meeting of stockholders,


•	a requirement that stockholders provide advance notice of any stockholder nominations of directors or any proposal of new business to be considered at any meeting of stockholders,


•	a requirement that the affirmative vote of at least 66 2/3% of our shares be obtained to amend or repeal any provision of our by-laws or the provision of our certificate of incorporation relating to amendments to our by-laws,


•	a requirement that the affirmative vote of at least 80% of our shares be obtained to amend or repeal the provisions of our certificate of incorporation relating to the election and removal of directors, the classified board or the right to act by written consent,

•

a requirement that the affirmative vote of at least 80% of our shares be obtained for business combinations unless approved by a majority of the members of the Board of Directors and, in the event that the other party to the business combination is the beneficial owner of 5% or more of our shares, a majority of the members of Board of Directors in office prior to the time such other party became the beneficial owner of 5% or more of our shares,


•	a fair price provision, and


•	a requirement that the affirmative vote of at least 90% of our shares be obtained to amend or repeal the fair price provision.

In addition to the provisions in our certificate of incorporation and by-laws, Section 203 of the Delaware General Corporation Law generally provides that a corporation may not engage in any business combination with any interested stockholder during the three-year period following the time that such stockholder becomes an interested stockholder, unless a majority of the directors then in office approves either the business combination or the transaction that results in the stockholder becoming an interested stockholder or specified stockholder approval requirements are met.

Our business and operations could suffer in the event of security breaches.

Attempts by others to gain unauthorized access to our information technology systems are becoming more sophisticated and are

Table of Contents

sometimes successful. These attempts, which might be related to industrial or other espionage, include covertly introducing malware to our computers and networks and impersonating authorized users, among others. We seek to detect and investigate all security incidents and to prevent their recurrence, but in some cases, we might be unaware of an incident or its magnitude and effects. The theft, unauthorized use or publication of our intellectual property and/or confidential business information could harm our competitive position, reduce the value of our investment in research and development and other strategic initiatives or otherwise adversely affect our business. To the extent that any security breach results in inappropriate disclosure of our customers' or licensees' confidential information, we may incur liability as a result. In addition, we expect to devote additional resources to the security of our information technology systems.

Disruptions in global credit and financial markets could materially and adversely affect our business and results of operations.

There is significant uncertainty regarding the stability of global credit and financial markets, exacerbated by the ongoing European debt crisis. These economic uncertainties may lead consumers and businesses to postpone spending, which may cause our customers to cancel, decrease or delay their existing and future orders for our products and make it difficult for us to accurately forecast and plan our future business activities. Uncertainty regarding the future stability of the Euro Zone could cause the value of the Euro to deteriorate, thus reducing the purchasing power and demand from of our European customers. In addition, financial difficulties experienced by our suppliers or distributors could result in product delays and increased accounts receivable defaults. During the past few years, many governments adopted stimulus or spending programs designed to ease the economic impact of the crisis. Some of our businesses benefited from these stimulus programs and there can be no assurance that such programs will continue in the future. If economic conditions deteriorate, we may record additional charges relating to restructuring costs or the impairment of assets and our business and results of operations could be materially and adversely affected.

NET REVENUE



	Fiscal Years Ended
	September 28, 2012		Change	September 30, 2011		Change	October 1, 2010
(dollars in thousands)
Net revenue	$	1,568,581	10.5%	$	1,418,922	32.4%	$	1,071,849

We market and sell our products directly to original equipment manufacturers of communications and electronics products, third-party original design manufacturers, contract manufacturers, and indirectly through electronic components distributors. We periodically enter into revenue generating arrangements that leverage our broad intellectual property portfolio by licensing or selling our non-core patents or other intellectual property. We anticipate continuing this intellectual property strategy in future periods.

Overall revenue in fiscal year 2012 increased by $149.7 million or 10.5% . The increase in revenue was primarily driven by sales of our expanded product portfolio consisting of new products from the SiGe and AATI acquisitions. In addition, we benefited from sales of new internally developed products for medical, automotive, military and industrial vertical markets and our increasing addressable content per device as the smartphone upgrade cycle continued to displace traditional 2G cellular phones.

Overall revenue in fiscal year 2011 increased by $347.1 million , or 32.4% , from fiscal year 2010. This revenue increase was principally driven by an increase in our growing addressable market, coupled with increasing market share and the higher overall demand for our products used in mobile internet, wireless infrastructure, energy management and diversified analog applications. In addition, we benefited from the incremental revenue associated with the acquisition of SiGe during fiscal year 2011.

GROSS PROFIT



	Fiscal Years Ended
	September 28, 2012			Change	September 30, 2011			Change	October 1, 2010
(dollars in thousands)
Gross profit	$	667,097		7.5%	$	620,304		35.8%	$	456,833
% of net revenue	42.5		%		43.7		%		42.6		%

Gross profit represents net revenue less cost of goods sold. Our cost of goods sold consists primarily of purchased materials, labor and overhead (including depreciation and share-based compensation expense) associated with product manufacturing. Erosion of average selling prices of established products is typical of the semiconductor industry. Consistent with trends in the industry, we anticipate that average selling prices for our established products will continue to decline at a normalized rate of 5 to 10 percent per year. As part of our normal course of business, we mitigate the gross margin impact of declining average selling prices with efforts to increase unit volumes, reduce material costs and lower manufacturing costs of existing products and by introducing new and higher value-added products.

Gross profit was $46.8 million greater for the fiscal year ended September 28, 2012 than gross profit for the prior fiscal year. The increase in gross profit was the result of higher unit volumes and lower overall per unit material and manufacturing costs with an aggregate gross profit benefit of approximately $151.7 million. These benefits were offset by the erosion of average selling price, unfavorable changes in product mix, the impact of the fair value step-up of acquired inventory primarily related to AATI and SiGe and higher share-based compensation expense which combined to negatively impact gross profit by approximately $104.9 million. As a result of these impacts, gross profit margin decreased from 43.7% for the fiscal year ended September 30, 2011 to 42.5% for the fiscal year ended September 28, 2012 .

We increased our gross profit by $163.5 million for the fiscal year ended September 30, 2011 as compared to the prior fiscal year, resulting in a 110 basis point expansion in gross profit margin to 43.7% . This increase was principally the result of enhanced product mix, lower manufacturing costs as a result of higher factory utilization, and the increase in net revenue.

During fiscal 2012 and 2011 we continued to benefit from higher contribution margins associated with the licensing and/or sale of intellectual property.

RESEARCH AND DEVELOPMENT



	Fiscal Years Ended
	September 28, 2012			Change	September 30, 2011			Change	October 1, 2010
(dollars in thousands)
Research and development	$	212,534		26.0%	$	168,637		25.7%	$	134,140
% of net revenue	13.5		%		11.9		%		12.5		%

Research and development expenses consist primarily of direct personnel costs including share-based compensation expense, costs for pre-production evaluation and testing of new devices, masks, engineering prototypes and design tool costs.

The 26.0% increase in research and development expense in fiscal year 2012 when compared to fiscal year 2011 is primarily attributable to higher head count and related compensation, including share-based compensation expense, resulting from the acquisition of SiGe and AATI, and to a lesser extent, to increased internal product design and development activity for our target markets. This resulted in total research and development expense increasing as a percentage of net revenue.

The 25.7% increase in research and development expenses in fiscal year 2011 when compared to fiscal year 2010 is principally attributable to higher head count and related employee and share-based compensation costs including those related to the SiGe acquisition. In addition, we increased design activity and expense in support of increased product development for our target markets. Research and development expenses decreased as a percentage of net revenue for fiscal year 2011 as a result of the increase in net revenue between fiscal 2011 and fiscal 2010 mentioned above.

SELLING, GENERAL AND ADMINISTRATIVE



	Fiscal Years Ended
	September 28, 2012			Change	September 30, 2011			Change	October 1, 2010
(dollars in thousands)
Selling, general and administrative	$	158,433		15.4%	$	137,238		16.4%	$	117,853
% of net revenue	10.1		%		9.7		%		11.0		%

Selling, general and administrative expenses include legal and related legal costs, accounting, treasury, human resources, information systems, customer service, bad debt expense, sales commissions, share-based compensation expense, advertising, marketing, costs associated with business combinations completed or contemplated during the period and other costs.

The increase for the fiscal year ended September 28, 2012 is primarily the result of incremental headcount and compensation expense (including share-based compensation) related to the acquisitions of AATI and SiGe (full year impact), increased acquisition and legal expense of $10.9 million primarily associated with the acquisition of AATI and $5.8 million in charges related to the resolution of contractual disputes. These charges were partially offset by a $5.4 million favorable change in the fair value of contingent consideration liabilities associated with the 2011 acquisitions. These factors resulted in selling, general and administrative expense increasing as a percentage of net revenue.

The increase in selling, general and administrative expenses for fiscal year 2011 as compared to fiscal year 2010 is principally due to the growth in the number of employees and related compensation expense (including share-based compensation), and to a lesser extent the increase related to professional fees associated with completed and pending acquisitions and a settlement of a contractual dispute. Selling, general and administrative expenses as a percentage of net revenue decreased for fiscal year 2011, as compared to fiscal year 2010, due to the increase in revenue between fiscal 2011 and fiscal 2010 mentioned above.

AMORTIZATION OF INTANGIBLES

% of net revenue	2.1		%		1.2		%		0.6		%

The increase in amortization expense in fiscal year 2012 is primarily related to intangible assets recognized in connection with our acquisitions of AATI in fiscal 2012 and the full year impact related to the acquisition of SiGe in fiscal 2011.

The increase in amortization expense in fiscal year 2011 is primarily related to the intangible assets that were recognized in connection with the acquisition of SiGe in fiscal 2011.

For additional information regarding the acquisitions and goodwill and intangible assets, see Note 3 and Note 8 of Item 8 of this Annual Report on Form 10-K, respectively.

The increase in restructuring and other charges for fiscal year 2012 relate primarily to employee and lease terminations to reduce redundancies associated with the acquisition of AATI.

The increase in restructuring and other charges for fiscal year 2011 relate primarily to employee and lease terminations to reduce redundancies associated with the acquisition of SiGe.

PROVISION FOR INCOME TAXES



	Fiscal Years Ended
	September 28, 2012			Change		September 30, 2011			Change		October 1, 2010
(dollars in thousands)
Provision for income taxes	$	52,898		(21.4	)%	$	67,301		16.5	%	$	57,780
% of net revenue	3.4		%			4.7		%			5.4		%

Income tax expense was $52.9 million for fiscal 2012, compared to $67.3 million for fiscal year 2011. The annual effective tax rate for fiscal year 2012 was 20.7% as compared to a tax rate of 22.9% for fiscal year 2011.

The annual effective tax rate for fiscal 2012 of 20.7% was less than the United States federal statutory rate of 35% primarily due to benefits of 16.8% related to foreign earnings taxed at a rate less than the United States federal rate, and benefits of 1.5% related to a domestic production activities deduction partially offset by income tax expense of 4.1% related to a change in our tax reserves.

As of September 28, 2012, the United States Congress has not taken action to extend the federal tax credit available under the Internal Revenue Code for research and development. Accordingly, the income tax provision for the year ended September 28, 2012 does not include the impact of such research and development tax credits earned after December 31, 2011.

On October 2, 2010, we expanded our presence in Asia by launching operations in Singapore. We operate under a tax holiday in Singapore, which is effective through September 30, 2020. The tax holiday is conditional upon our compliance in meeting certain employment and investment thresholds in Singapore.

The annual effective tax rate for fiscal 2011 of 22.9% was less than the United States federal statutory rate of 35% primarily due to benefits of 8.3% related to foreign earnings taxed at a rate less than the United States federal rate, benefits of 6.0% and 2.1% related to the research and development tax credits and domestic production activities deduction, respectively, which are partially offset by income tax expense of 3.2% related to a change in our tax reserves.

Cash Flow from Operating Activities:

Cash provided from operating activities is net income adjusted for certain non-cash items and changes in certain operating assets and liabilities. For fiscal year 2012 we generated $285.2 million in cash flow from operations, a decrease of $80.6 million when compared to $365.8 million generated in fiscal year 2011. The decrease in cash flow from operating activities during the fiscal year ended September 28, 2012 was related to lower net income combined with a net cash outflow from changes in operating assets and liabilities partially offset by an increase in non-cash amortization of intangibles, depreciation and share-based compensation expense. Specifically, the changes in operating assets were increases of $109.2 million in accounts receivable due to the timing of customer shipments towards the end of the fiscal year triggered by a need to respond to key customer program ramp-ups, an increase of $19.3 million in inventory in response to key customer program ramp-ups and $9.5 million in other current assets primarily relating to taxes and pre-paid assets. The offsetting changes in operating liabilities were increases of approximately $15.2 million in accounts payable related to the timing of vendor payments and $13.8 million in other current and long-term liabilities primarily related to long-term tax liabilities and changes in payroll related accruals.

Cash Flow from Investing Activities:

Cash flow from investing activities consists of cash paid for acquisitions, net of cash acquired, capital expenditures, cash received from the sale of capital assets and the sale and maturity of short-term and other investments. Net cash used in investing activities was $302.9 million during the fiscal year 2012, compared to $349.9 million during the fiscal year 2011. Net cash used in investing activities decreased primarily because we used more cash to acquire businesses in 2011 than we did to acquire AATI in 2012, in each instance, net of cash acquired. In fiscal year 2012 we used $229.6 million of cash, net of cash acquired, for the acquisition of AATI and we invested $94.1 million in capital expenditures, primarily related to the purchase of manufacturing equipment to support increased production at our assembly and test facility in Mexicali, Mexico and to a lesser extent, our wafer fabrication facilities located in California and Massachusetts. During fiscal year 2011, we paid invested $100.7 million in capital expenditures. Our uses of cash for investing activities during fiscal year 2012 were partially offset by $20.9 million in proceeds we received upon the sale and maturity of short-term investments acquired as part of our acquisition of AATI during the fiscal year ending September 28, 2012

Cash Flow from Financing Activities:

Cash flows from financing activities consist primarily of cash transactions related to debt, equity and payment of contingent consideration related to our fiscal 2011 acquisitions. During fiscal year 2012, we had net cash outflows of $86.2 million , compared to $59.0 million in fiscal year 2011. During fiscal year 2012 we had the following significant uses of cash:


•	$52.9 million related to the cash payment of contingent consideration obligation related to the acquisition of SiGe;


•	$48.0 million in connection with the redemption and retirement of the remaining $26.7 million aggregate principal amount of our 1.50% convertible subordinated notes due March 2012;


•	$18.6 million related to payroll tax withholdings on vesting of employee performance and restricted stock awards; and,


•	$12.4 million related to our repurchase of approximately 750,000 shares of our common stock pursuant to the share repurchase program approved by our Board of Directors on August 3, 2010.

These uses of cash were partially offset by the net proceeds from employee stock option exercises of $39.0 million and the tax benefit from stock option exercises of $6.8 million during fiscal 2012.

Liquidity:

Cash and cash equivalent balances (excluding restricted cash which is used to collateralize outstanding letters of credit for insurance and lease obligations) decreased by $103.8 million to $306.3 million at September 28, 2012 from $410.1 million at September 30, 2011 . During fiscal year 2012 we used $229.6 million in cash, net of cash acquired, in connection with the acquisition of AATI and paid cash of $94.1 million in capital expenditures, $52.9 million for contingent consideration obligations related to the acquisition of SiGe, $48.0 million to retire the remaining $26.7 million of aggregate principal amount of our 1.50% convertible subordinated notes due March 2012, and $12.4 million for share repurchases. During fiscal 2012 our cash provided by operations was $285.2 million . Our net cash position decreased by $77.7 million to $306.3 million at September 28, 2012 from $384.0 million at September 30, 2011 , after deducting our debt outstanding at September 30, 2011 . Based on our historical results of operations, we expect that our cash and cash equivalents on hand and the cash we expect to generate from operations will be sufficient to fund our research and development, capital expenditures, working capital and other cash requirements for at least the next 12 months. However, we cannot be certain that our cash from operations will be available in the future to fund all of our capital and operating requirements. In addition, any strategic investments and acquisitions that we may make may require additional capital resources. If we are unable to obtain sufficient cash or capital to meet our capital needs on a timely basis and on favorable terms, our business and operations could be materially and adversely affected.

Our invested cash balances primarily consist of money market funds where the underlying securities primarily consist of United States treasury obligations, United States agency obligations and repurchase agreements collateralized by United States Government and agency obligations. Our invested cash balances also include time deposits and certificates of deposit.

Our cash, cash equivalents and restricted cash balance of $307.1 million at September 28, 2012 consisted of $169.1 million held domestically and $138.0 million held by foreign subsidiaries. Of the cash, cash equivalents and restricted cash held by our foreign subsidiaries at September 28, 2012 , approximately $76.6 million is being and will be indefinitely reinvested outside of the United States and would be subject to material tax effects if repatriated to the United States. Accordingly, we do not intend to repatriate these funds.

OFF-BALANCE SHEET ARRANGEMENTS

We have no significant contractual obligations not fully recorded on our consolidated balance sheet or fully disclosed in the notes to our consolidated financial statements. We have no material off-balance sheet arrangements as defined in SEC Regulation S-K- 303(a)(4)(ii).

CRITICAL ACCOUNTING ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. The SEC has defined critical accounting policies as those that are both most important to the portrayal of our financial condition and results and which require our most difficult, complex or subjective judgments or estimates. Based on this definition, we believe our critical accounting policies include the policies of revenue recognition, inventory valuation, impairment of long-lived assets, business combinations, share-based compensation, loss contingencies and income taxes.

On an ongoing basis, we evaluate the judgments and estimates underlying all of our accounting policies. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures, and reported amounts of revenues and expenses. These estimates and assumptions are based on our best judgments. We evaluate our estimates and assumptions using historical experience and other factors, including the current economic environment, which we believe to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.

Our significant accounting policies are discussed in detail in Note 2 of Item 8 In this Annual Report on Form 10-K. We believe the following critical accounting policies affect the more significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition. We recognize revenue in accordance with Financial Accounting Standards Board's Accounting Standards Codification ("ASC") 605 Revenue Recognition net of estimated reserves. We maintain revenue reserves for product returns and allowances for price protection and stock rotation for certain electronic component distributors. These reserves are based on historical experience or specific identification of a contractual arrangement necessitating a revenue reserve.

Our revenue recognition accounting methodology contains uncertainties because it requires management to make assumptions and to apply judgment to estimate the value of future credits to customers for product returns, price protection and stock rotation. Our estimates of the amount and timing of the reserves is based primarily on historical experience and specific contractual arrangements. Historically, we have not experienced material differences between our estimated sales reserves and actual results.

Inventory Valuation. We value our inventory at the lower of cost of the inventory or fair market value through the establishment of excess and obsolete inventory reserves. Our reserve is based on a detailed analysis of forecasted demand in relation to on-hand inventory, saleability of our inventory, general market conditions, and product life cycles.

Our inventory reserves contain uncertainties because the calculation requires management to make assumptions and to apply judgment regarding historical experience, forecasted demand and technological obsolescence. Historically, we have not experienced material

Table of Contents

differences between our estimated inventory reserves and actual results.

Impairment of Long-Lived Assets. We assess the impairment of long-lived assets, including goodwill, on an ongoing basis and whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

We evaluate goodwill and other indefinite-lived intangible assets for impairment annually on the first day of the fiscal fourth quarter and whenever events or circumstances arise that may indicate that the carrying value of the goodwill or other indefinite-lived intangibles may not be recoverable. Pursuant to the guidance provided under ASC 280 Segment Reporting , we have determined that we have one reporting unit for the purposes of allocating and testing goodwill.

The impairment evaluation of goodwill involves comparing the fair value to the carrying value of the reporting unit. We use the market price of the Company's stock adjusted for a market premium to calculate the fair value of the reporting unit. If the fair value exceeds the carrying value, then it is concluded that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, a second step is required to measure the possible goodwill impairment loss.

In the second step, if required, we would use a discounted cash flow methodology to determine the implied fair value of our goodwill. The implied fair value of the reporting unit's goodwill would then be compared to the carrying value of the goodwill. If the carrying value of the goodwill exceeds the implied fair value of the goodwill, we would recognize a loss equal to the excess.

Our impairment analyses contain uncertainties because it requires management to make assumptions and to apply judgment to items such as; estimate control premiums, discount rate, future cash flows, the profitability of future business strategies and useful lives.

Business Combinations. The Company has applied significant estimates and judgments in order to determine the fair value of the identified tangible and intangible assets acquired, liabilities assumed and the contingent consideration recorded as part of business combinations. The value of all assets and liabilities are recognized at fair value as of the acquisition date.

In measuring the fair value, the Company utilizes valuation techniques consistent with the market approach, income approach and/ or cost approach. The valuation of the identifiable assets and liabilities includes assumptions such as, projected revenue, royalty rates, weighted average cost of capital, discount rates, estimated useful lives, etc. These assessments can be significantly affected by management's judgments.

Share-Based Compensation . We have a share-based compensation plan which includes non-qualified stock options, share awards, employee stock purchase plan and other special share-based awards. See Note 11 of Item 8 of this Annual Report on Form 10-K for a detailed listing and complete discussion of our share-based compensation programs.

We determine the fair value of our non-qualified share-based compensation at the date of grant using the Black-Scholes options-pricing model. Our determination of fair value of share-based payment awards on the date of grant contains 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 award, risk-free rate, and the expected life. The Black-Scholes value, combined with our estimated forfeiture rate, is used to determine the compensation expense to be recognized over the life of the options. For performance based awards, we determine the fair value based on the grant date value of the Company's stock. These awards are expensed based on an estimate of the most probably outcome of the underlying performance metric. Management periodically evaluates these assumptions and updates share-based compensation expense accordingly.

Option-pricing models and generally accepted valuation techniques require management to make assumptions and to apply judgment to determine the fair value of our awards. These assumptions and judgments include estimating the future volatility of our stock price, future employee turnover rates and future employee stock option exercise behaviors. Changes in these assumptions can materially affect the fair value estimate and stock based compensation recognized by the Company.

Loss Contingencies. The outcomes of legal proceedings and claims brought against us are subject to significant uncertainties. Estimated loss from a loss contingency such as a legal proceeding or claim should be accrued by a charge to income if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. Disclosure of a material loss contingency is required if there is at least a reasonable possibility that a loss has been incurred.

Our loss contingency analysis contains uncertainties because it requires management to assess the degree of probability of an unfavorable outcome and to make a reasonable estimate of the amount of potential loss.

Table of Contents

Income Taxes. We account for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between tax and financial reporting. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. We record a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. Significant management judgment is required in developing our provision for income taxes, including the determination of deferred tax assets and liabilities and any valuation allowances that might be required against the deferred tax assets. ASC 740 Income Taxes ("ASC 740"), clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with GAAP. ASC 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This statement also provides guidance on derecognition, classification, interest and penalties, accounting in the interim periods and disclosure.

The application of tax laws and regulations to calculate our tax liabilities is subject to legal and factual interpretation, judgment, and uncertainty in a multitude of jurisdictions. Tax laws and regulations themselves are subject to change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations, and court rulings. We recognize potential liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes and interest will be due. We record an amount as an estimate of probable additional income tax liability at the largest amount that we feel is more likely than not, based upon the technical merits of the position, to be sustained upon audit by the relevant tax authority. We record a valuation allowance against deferred tax assets that we feel are more likely than not to not be realized.

OTHER MATTERS

Inflation did not have a material impact upon our results of operations during the three-year period ended September 28, 2012 .

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We are subject to investment risk, interest rate risk, and foreign exchange rate risk as described below.

Investment and Interest Rate Risk

Our exposure to interest rate and general market risks relates principally to our investment portfolio consisted of the following (in thousands):



	As of
	September 28, 2012
Cash and cash equivalents (time deposits and money market funds)	$	306,293
Restricted cash (time deposits and certificates of deposit)	817
Available for sale securities (auction rate securities) at carrying value	3,093
	$	310,203

The main objective of our investment activities is the liquidity and preservation of capital. In general, our cash and cash equivalent investments have short-term maturity periods which dampen the impact of significant market or interest rate risk. Credit risk associated with our investments is not material as our investment policy prescribes high credit quality standards and limits the amount of credit exposure to any one issuer. We currently do not use derivative instruments for trading, speculative or investment purposes; however, we may use derivatives in the future.

We are subject to overall financial market risks, such as changes in market liquidity, credit quality and interest rates. Securities that are available for sale carry a longer maturity period (in some cases original contractual maturities exceed ten years).

In the event the market conditions change in the future and our auction rate security becomes fully and permanently impaired, the impact to income before income taxes would be the par value of the auction rate security of approximately $4.0 million as of September 28, 2012.

Based on the results of operations for the fiscal year ended September 28, 2012, a hypothetical reduction in interest rates to zero on our cash and cash equivalents would result in a reduction of interest income of approximately $0.1 million to income before

Table of Contents

income taxes.

Given the low interest rate environment, the objectives of our investment activities, and the relatively low interest income generated from our cash and cash equivalents and other investments, we do not believe that market, investment or interest rate risks pose material exposures to our current business or results of operations.

Exchange Rate Risk

Substantially all sales to customers and arrangements with third-party manufacturers provide for pricing and payment in United States dollars, thereby reducing the impact of foreign exchange rate fluctuations on our results. A small percentage of our international operational expenses are denominated in foreign currencies. Exchange rate volatility could negatively or positively impact those operating costs. For the fiscal years ended September 28, 2012 , September 30, 2011 , and October 1, 2010 , the Company had foreign exchange (losses)/gain of $(0.4) million, $0.3 million, and $(0.6) million, respectively. Increases in the value of the U.S. dollar relative to other currencies could make our products more expensive, which could negatively impact our ability to compete. Conversely, decreases in the value of the U.S. dollar relative to other currencies could result in our suppliers raising their prices to continue doing business with us. Fluctuations in currency exchange rates could have a greater effect on our business in the future to the extent our expenses increasingly become denominated in foreign currencies.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Skyworks Solutions, Inc.:

We have audited the accompanying consolidated balance sheets of Skyworks Solutions, Inc. and subsidiaries as of September 28, 2012 and September 30, 2011, and the related consolidated statements of operations, cash flows, and stockholders' equity and comprehensive income for each of the years in the three-year period ended September 28, 2012. In connection with our audits of the consolidated financial statements, we also have audited the financial statement schedule listed in Item 15 of the 2012 Form 10-K. We also have audited Skyworks Solutions, Inc.'s internal control over financial reporting as of September 28, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Skyworks Solutions, Inc.'s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements and financial statement 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 consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also 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 generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of 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 Skyworks Solutions, Inc. and subsidiaries as of September 28, 2012 and September 30, 2011, and the results of its operations and its cash flows for each of the years in the three-year period ended September 28, 2012, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statement taken as a whole, presents fairly, in all material respects, the information set forth therein. Also in our opinion, Skyworks Solutions, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of September 28, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Skyworks Solutions, Inc. acquired Advanced Analogic Technologies Inc. during 2012, and management excluded from its assessment of the effectiveness of Skyworks Solutions, Inc. internal control over financial reporting as of September 28, 2012, Advanced Analogic Technologies Inc.'s internal control over financial reporting associated with total assets of 13.7% (of which 8.1% represented goodwill and intangible assets included within the scope of the assessment) included in the consolidated financial statements of Skyworks Solutions, Inc. as of September 28, 2012. Our audit of internal control over financial reporting of Skyworks Solutions, Inc. also excluded an evaluation of the internal control over financial reporting of Advanced Analogic Technologies Inc.

The Company has evaluated subsequent events through the date of issuance of the audited consolidated financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

All majority owned subsidiaries are included in the Company’s Consolidated Financial Statements and all intercompany balances are eliminated in consolidation.

FISCAL YEAR

The Company’s fiscal year ends on the Friday closest to September 30. Fiscal years 2012, 2011 and 2010 each consisted of 52 weeks and ended on September 28, 2012, September 30, 2011 and October 1, 2010, respectively.

USE OF ESTIMATES

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company evaluates its estimates on an ongoing basis using historical experience and other factors, including the current economic environment. Significant judgment is required in determining the reserves for and fair value of items such as reserves for inventory, income taxes, share-based compensation, loss contingencies, bad debt, contingent consideration associated with business combinations, and fair value assessments of assets and liabilities. In addition, significant judgment is required in determining whether a potential indicator of impairment of long-lived assets exists and in estimating future cash flows for any necessary impairment tests. Management’s estimates could differ significantly from actual results.

REVENUE RECOGNITION

Revenue from product sales is recognized when there is persuasive evidence of an arrangement, the price to the buyer is fixed and determinable, delivery and transfer of title have occurred in accordance with the shipping terms specified in the arrangement with the customer and collectability is reasonable assured. Revenue from license fees and intellectual property is recognized when due and payable, and all other criteria of the Financial Accounting Standards Board's Accounting Standards Codification ("ASC") 605 Revenue Recognition, have been met. The Company ships product on consignment to certain customers and only recognizes revenue when the customer notifies the Company that the inventory has been consumed. Revenue recognition is deferred in all instances where the earnings process is incomplete. Certain product sales are made to electronic component distributors under agreements allowing for price protection and/or a right of return (stock rotation) on unsold products. A reserve for sales returns and allowances for customers is recorded based on historical experience or specific identification of a contractual arrangement necessitating a revenue reserve.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

The Company maintains general allowances for doubtful accounts for losses that they estimate will arise from their customers’ inability to make required payments. These reserves require management to apply judgment in deriving estimates. As the Company becomes aware of any specific receivables which may be uncollectable, they perform additional analysis and reserves are recorded if deemed necessary. Determination of such additional specific reserves require management to make judgments and estimates pertaining to factors such as a customer’s credit worthiness, intent and ability to pay, and overall financial position. If the data the

Table of Contents

Company uses to calculate the allowance for doubtful accounts does not reflect the future ability to collect outstanding receivables, additional provisions for doubtful accounts may be needed and its results of operations could be materially affected.

CASH AND CASH EQUIVALENTS

The Company’s cash and cash equivalents primarily consist of cash money market funds where the underlying securities primarily consist of United States treasury obligations, United States agency obligations, and repurchase agreements collateralized by United States Government and agency obligations with weighted average maturities of 90 days or less.

RESTRICTED CASH

Restricted cash is primarily used to collateralize the Company’s outstanding letters of credit for insurance and lease obligations.

INVESTMENTS

The Company’s investments are classified as available for sale and currently consist of auction rate securities (“ARS”). Available for sale securities are carried at fair value with unrealized holding gains or losses being recorded in other comprehensive income. Gains or losses are included in earnings in the period in which they are realized.

FINANCIAL INSTRUMENTS

The carrying value of cash and cash equivalents, accounts receivable, other current assets, accounts payable, short-term debt and accrued liabilities approximates fair value due to short-term maturities of these assets and liabilities. Fair values of long-term investments are based on quoted market prices if available, and if not available a fair value is determined through a discounted cash flow analysis at the date of measurement.

INVENTORY

Inventories are stated at the lower of cost, determined on a first-in, first-out basis, or market. Each quarter, the Company estimates and establishes reserves for excess, obsolete or unmarketable inventory. These reserves are generally equal to the historical cost basis of the excess or obsolete inventory and once recorded are considered permanent adjustments. Calculation of the reserves requires management to use judgment and make assumptions about forecasted demand in relation to the inventory on hand, competitiveness of its product offerings, general market conditions and product life cycles upon which the reserves are based. When inventory on hand exceeds foreseeable demand (generally in excess of twelve months), reserves are established for the value of such inventory that is not expected to be sold.

If actual demand and market conditions are less favorable than those the Company projects, additional inventory reserves may be required and its results of operations could be materially affected. Some or all of the inventories that have been reserved may be retained and made available for sale; however, they are generally scrapped over time.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method. Significant renewals and betterments are capitalized and equipment taken out of service is written off. Maintenance and repairs, as well as renewals of a minor amount, are expensed as incurred.

Estimated useful lives used for depreciation purposes are five to 30 years for buildings and improvements and three to 10 years for machinery and equipment. Leasehold improvements are depreciated over the lesser of the economic life or the life of the associated lease.

VALUATION OF LONG-LIVED ASSETS

Definite lived intangible assets are carried at cost less accumulated amortization. Amortization is calculated on a straight-line basis over the estimated useful lives of the assets. Carrying values for long-lived assets and definite lived intangible assets, which exclude goodwill, are reviewed for possible impairment as circumstances warrant. Factors considered important that could result in an impairment review include significant underperformance relative to expected, historical or projected future operating results, significant changes in the manner of use of assets or the Company’s business strategy, or significant negative industry or economic trends. In addition, impairment reviews are conducted at the judgment of management whenever asset / asset group values are deemed

Table of Contents

to be unrecoverable relative to future undiscounted cash flows expected to be generated by that particular asset / asset group. The determination of recoverability is based on an estimate of undiscounted cash flows expected to result from the use of an asset / asset group and its eventual disposition. Such estimates require management to exercise judgment and make assumptions regarding factors such as future revenue streams, operating expenditures, cost allocation and asset utilization levels, all of which collectively impact future operating performance. The Company’s estimates of undiscounted cash flows may differ from actual cash flows due to, among other things, technological changes, economic conditions, changes to its business model or changes in its operating performance. If the sum of the undiscounted cash flows (excluding interest) is less than the carrying value of an asset/asset group, the Company would recognize an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the asset or asset group.

GOODWILL AND INDEFINITE INTANGIBLE ASSETS

Goodwill and intangible assets with indefinite useful lives are not amortized but are tested at least annually for impairment in accordance with the provisions of ASC 350 Intangibles-Goodwill and Other (“ASC 350”) . Intangible assets with indefinite useful lives comprise an insignificant portion of the total book value of the Company’s intangible assets. The Company assesses the need to test its goodwill for impairment on a regular basis. Pursuant to the guidance provided under ASC 280 Segment Reporting (see Note 18 of Item 8 of this Annual Report on Form 10-K for further discussion), the Company has determined that it has one reporting unit for the purposes of allocating and testing goodwill under ASC 350.

The goodwill impairment test is a two-step process. The first step of the Company’s impairment analysis compares its fair value to its net book value to determine if there is an indicator of impairment. To determine fair value, ASC 350 allows for the use of several valuation methodologies, although it states that quoted market prices are the best evidence of fair value and shall be used as the basis for measuring fair value where available. In the Company’s assessment of its fair value, the Company considers the closing price of its common stock on the selected testing date, the number of shares of its common stock outstanding and other marketplace activity such as a related control premium. If the calculated fair value is determined to be less than the book value of the Company, then the Company performs step two of the impairment analysis. Step two of the analysis compares the implied fair value of the Company’s goodwill to its book value. If the book value of the Company’s goodwill exceeds its implied fair value, an impairment loss is recognized equal to that excess. In step two of the Company’s annual impairment analysis, if required, the Company primarily uses the income approach methodology of valuation, which includes the discounted cash flow method as well as other generally accepted valuation methodologies, to determine the implied fair value of the Company’s goodwill. Significant management judgment is required in preparing the forecasts of future operating results that are used in the discounted cash flow method of valuation. Should step two of the impairment test be required, the estimates management would use would be consistent with the plans and estimates that the Company uses to manage its business. In addition to testing goodwill for impairment on an annual basis, factors such as unexpected adverse business conditions, deterioration of the economic climate, unanticipated technological changes, adverse changes in the competitive environment, loss of key personnel and acts by governments and courts, are considered by management and may signal that the Company’s intangible assets including goodwill have become impaired and result in additional interim impairment testing.

In fiscal year 2012, the Company performed an impairment test of its goodwill as of the first day of the fourth fiscal quarter in accordance with the Company’s regularly scheduled annual testing. The results of this test indicated that the Company’s goodwill was not impaired based on step one of the test; accordingly step two of the test was not performed.

BUSINESS COMBINATIONS

The Company uses the acquisition method of accounting for business combinations and recognizes assets acquired and liabilities assumed measured at their fair values on the date acquired. Goodwill represents the excess of the purchase price over the fair value of the net assets. The fair values of the assets and liabilities acquired are determined based upon the Company’s valuation. The valuation involves making significant estimates and assumptions which are based on detailed financial models including the projection of future cash flows, the weighted average cost of capital and any cost savings that are expected to be derived in the future.

SHARE-BASED COMPENSATION

The Company applies ASC 718 Compensation-Stock Compensation (“ASC 718”) which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including non-qualified employee stock options, share awards, employee stock purchase plan and other special share-based awards based on estimated fair values. The Company adopted ASC 718 using the modified prospective transition method, which requires the application of the applicable accounting standard as of October 1, 2005, the first day of the Company’s fiscal year 2006.

Table of Contents

The fair value of share-based awards is amortized over the requisite service period, which is defined as the period during which an employee is required to provide service in exchange for an award. The Company uses a straight-line attribution method for all grants that include only a service condition. Due to the existence of both performance and service conditions, certain restricted stock grants are expensed over the service period for each separately vesting tranche.

Share-based compensation expense recognized during the period is based on the value of the portion of share-based payment awards that is ultimately expected to vest during the period. Share-based compensation expense recognized in the Company’s Consolidated Statement of Operations for the fiscal year ended September 28, 2012 only included share-based payment awards granted subsequent to September 30, 2005 based on the grant date fair value estimated in accordance with the provisions of ASC 718. As share-based compensation expense recognized in the Consolidated Statement of Operations for the fiscal year ended September 28, 2012 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Upon adoption of ASC 718, the Company elected to retain its method of valuation for share-based awards using the Black-Scholes option-pricing model (“Black-Scholes model”) which was also previously used for the Company’s pro forma information required under the previous authoritative literature governing stock compensation expense. The Company’s determination of fair value of share-based payment awards on the date of grant using the Black-Scholes model is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to; the Company’s expected stock price volatility over the term of the awards, risk free interest rate, and actual and projected employee stock option exercise behaviors. The determination of fair value of restricted share awards is based on the value of the Company's stock on the date of grant. The Company may from time to time offer more complex awards with market-based performance conditions. In the event the Company offers its employees such awards, the Company would employ a Monte Carlo simulation valuation method to calculate the potential outcome for awards and establishes fair value based on the most likely outcome.

DEFERRED FINANCING COSTS

Financing costs are capitalized as an asset on the Company’s balance sheet and amortized on a straight-line basis over the life of the financing. If debt is extinguished early, a proportionate amount of deferred financing costs is charged to earnings.

CURRENCIES

The Company’s functional currency for all operations worldwide is the U.S. dollar. Accordingly, gains and losses related to foreign currency transactions, conversion of foreign denominated cash balances and translation of foreign currency financial statements are included in current results.

INCOME TAXES

The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. This method also requires the recognition of future tax benefits such as net operating loss carry forwards, to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The carrying value of the Company's net deferred tax assets assumes the Company will be able to generate sufficient future taxable income in certain tax jurisdictions, based on estimates and assumptions. If these estimates and related assumptions change in the future, the Company may be required to record additional valuation allowances against its deferred tax assets resulting in additional income tax expense in its consolidated statement of operations. Management evaluates the realizability of the deferred tax assets and assesses the adequacy of the valuation allowance quarterly. Likewise, in the event the Company were to determine that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, an adjustment to the deferred tax assets would increase income or decrease the carrying value of goodwill in the period such determination was made.

The determination of recording or releasing tax valuation allowances is made, in part, pursuant to an assessment performed by management regarding the likelihood that the Company will generate future taxable income against which benefits of its deferred tax assets may or may not be realized. This assessment requires management to exercise significant judgment and make estimates with respect to its ability to generate revenues, gross profits, operating income and taxable income in future periods. Amongst other factors, management must make assumptions regarding overall business and semiconductor industry conditions, operating

efficiencies, the Company's ability to develop products to its customers' specifications, technological change, the competitive environment and changes in regulatory requirements which may impact its ability to generate taxable income and, in turn, realize the value of its deferred tax assets.

The calculation of the Company’s tax liabilities includes addressing uncertainties in the application of complex tax regulations and is based on the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.

The Company recognizes liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based on its recognition threshold and measurement attribute of whether it is more likely than not that the positions the Company has taken in tax filings will be sustained upon tax audit, and the extent to which additional taxes would be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period in which it is determined the liabilities are no longer necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result. The Company recognizes any interest and penalties, if incurred, on any unrecognized tax benefits as a component of income tax expense.

RESEARCH AND DEVELOPMENT COSTS

Research and development costs are expensed as incurred.

LOSS CONTINGENCIES

The Company records its best estimates of a loss contingency when it is considered probable and the amount can be reasonably estimated. When a range of loss can be reasonably estimated with no best estimate in the range, the Company records the minimum estimated liability related to the claim. As additional information becomes available, the Company assesses the potential liability related to the Company's pending loss contingency and revises its estimates. The Company's records its legal costs as expense in the period in which they are incurred.

ACCUMULATED OTHER COMPREHENSIVE LOSS

The Company accounts for comprehensive loss in accordance with the provisions of ASC 220 - Comprehensive Income (“ASC 220”). ASC 220 is a financial statement presentation standard that requires the Company to disclose non-owner changes included in equity but not included in net income or loss. Accumulated other comprehensive loss presented in the financial statements consists of adjustments to the Company’s auction rate securities and minimum pension liability as follows (in thousands):



	Pension Adjustments		Auction Rate Securities Adjustment		Accumulated Other Comprehensive Loss

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 2011, the Financial Accounting Standards Board revised the authoritative guidance for comprehensive income to require an entity to present total comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements and eliminated the option to present the components of other comprehensive income as part of the statement of equity. The guidance will be effective for us beginning in the first quarter of fiscal 2013 and should be applied retrospectively. The adoption of the guidance will impact the presentation of the financial statements only and will not impact our financial position, results of operations or cash flows.

In September 2011, the Financial Accounting Standards Board revised the authoritative guidance for goodwill and other intangibles to allow entities the ability to first assess the qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. The guidance will be effective for us beginning in fiscal 2013. The adoption of this guidance is not expected to impact our annual goodwill impairment test, financial position or results of operations.

Table of Contents

In June 2012, The Financial Accounting Standards Board proposed guidance regarding the disclosures for liquidity and interest rate disclosures. Comments on the exposure draft were due in September 2012. This Accounting Standards Update has not been finalized as of the date of this filing; however the Company does not believe this guidance will impact our financial position or results of operations.

In July 2012, the Financial Accounting Standards Board revised the authoritative guidance for indefinite-lived intangible asset impairment testing to allow entities the ability to first assess the qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired. The guidance will be effective for us beginning in fiscal 2013. The adoption of this guidance is not expected to impact our indefinite-lived intangible asset impairment testing, financial position or results of operations.

3. BUSINESS COMBINATIONS

On January 9, 2012 , the Company acquired Advanced Analogic Technologies Inc. ("AATI"). The Company acquired all of the outstanding shares of AATI in exchange for an aggregate purchase price of $277.3 million , substantially comprised of cash consideration. AATI is an analog semiconductor company focused on enabling energy-efficient power management devices for consumer electronics, computing and communications markets. The acquisition expands the Company's product portfolio across new vertical markets with highly complementary analog semiconductor products including battery chargers, DC/DC converters, voltage regulators and LED drivers.

The allocation of the purchase price to the assets and liabilities recognized in the Company’s acquisition of AATI was not finalized at the time of filing this annual report on Form 10-K. The preliminary allocation of the purchase price reflected in the accompanying financial statements is based upon estimates and assumptions which are subject to change within the measurement period (up to one year from the acquisition date as prescribed in the ASC 805 Business Combinations) . The preliminary allocation of the purchase price is based on the estimated fair values of the assets acquired and liabilities assumed by major class related to the AATI acquisition and are reflected, as of the acquisition date, in the accompanying financial statements as follows (in thousands):



	As of
Estimated fair value of assets acquired	January 9, 2012
Cash	$	42,605
Short-term investments	20,900
Accounts receivable	10,962
Inventory	15,470
Deferred tax assets	22,219
Property, plant and equipment	3,693
Other assets	2,139
Identifiable intangible assets	40,240
Goodwill	133,958
Total assets acquired	292,186
Liabilities assumed	(14,842		)
Estimated fair value of assets acquired	$	277,344

The preliminary amount of the AATI purchase price allocated to goodwill of $134.0 million (including measurement period adjustments recognized) represents the expected synergies from cost efficiencies and cross-selling opportunities. The Company expects that substantially all of the goodwill recognized as a result of the AATI acquisition will not be deductible for tax purposes.

The preliminary amount of the AATI purchase price allocated to identifiable intangible assets recognized in the acquisition of AATI and the respective useful lives of such intangible assets as of January 9, 2012 were as follows (in thousands):

Table of Contents



	Fair Value		Estimated Useful Life (Years)
Customer relationships	$	21,200	4.7
Developed technology	15,500		5.0
In process research and development ("IPR&D")	1,540		TBD
Trade name	900		5.0
Backlog	1,100		0.3
Total identifiable intangible assets	$	40,240

Customer relationships represent the fair value of established relationships with original equipment manufacturers and distributors. Developed technology primarily represents the fair value of acquired AATI patented and unpatented technologies related to product designs. IPR&D represents the fair value of incomplete AATI research and development projects that had not reached technological feasibility but are expected to generate future economic benefit as of the acquisition date, January 9, 2012. Because of the uncertainty related to the completion of these projects, the Company has determined that the amortization period will be established when the projects reach technological feasibility or are discontinued. If a project is discontinued or fails to meet technological feasibility, the value associated with that project will be written off in the period the determination is made. The trade name line item in the table above represents the brand and name recognition associated with the marketing of AATI products and was determined to have a finite life. Backlog represents the fair value of AATI unfilled firm orders as of the acquisition date. All intangible assets acquired in connection with the AATI acquisition will be amortized on a straight-line basis over their respective estimated useful lives. The estimated fair values of the intangible assets acquired were primarily determined using the income approach based on significant inputs that were not observed. The Company considers the fair value of each of the acquired intangible assets to be Level 3 assets due to the significant estimates and assumptions used by management in establishing the estimated fair values. See Note 5, Fair Value in these Notes to the Consolidated Financial Statements for the definition of Level 3 assets.

Net revenue and net income for AATI have been included in the Consolidated Statements of Operations from the acquisition date through the end of the fiscal year on September 28, 2012 . The impact of AATI's ongoing operations on the Company's net revenue and net income were not significant for the fiscal years ended September 28, 2012 . The Company recognized transaction related costs associated with the AATI acquisition of approximately $10.9 million , including arbitration costs, during the fiscal year ended September 28, 2012 which were included within the sales, administrative and general expense.

The unaudited pro forma financial results for the fiscal years ended September 28, 2012 and September 30, 2011 combine the unaudited historical results of Skyworks with the unaudited historical results of AATI for the fiscal year ended September 28, 2012 and September 30, 2011 , respectively. The results include the effects of unaudited pro forma adjustments as if AATI was acquired at the beginning of the prior fiscal year, October 2, 2010. The unaudited pro forma results presented include amortization charges for acquired intangible assets, adjustments for increases in the fair value of acquired inventory, other charges and related tax effects. The pro forma financial results presented below do not include any anticipated synergies or other expected benefits of the acquisition. These unaudited results are presented for informational purposes only and are not necessarily indicative of future operations (in thousands, except per share amounts):

4. MARKETABLE SECURITIES

The Company accounts for its investment in marketable securities in accordance with ASC 320- Investments-Debt and Equity Securities , and classifies them as “available for sale.” At September 28, 2012 , these securities included $4.0 million of par value ARS, with a carrying value of $3.1 million as compared to the September 30, 2011 balances of $3.2 million and $2.3 million , respectively. The ARS balances are scheduled to mature through 2017. The increase in the balances held at September 28, 2012 relates to ARS acquired as a result of the acquisition of AATI with a par and carrying value of approximately $0.8 million . The difference between the par and carrying values is categorized as a temporary loss in other comprehensive income. The Company receives the scheduled interest payments in accordance with the terms of the securities and evaluates the appropriate accounting treatment in each period presented.

In addition to the ARS, the Company acquired $20.9 million in US treasury bills as part of the acquisition of AATI on January 9, 2012. These securities matured or were sold prior to September 28, 2012 .

5. FAIR VALUE

Fair value is the price that would be received from selling an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants as of the measurement date. Applicable accounting guidance provides a hierarchy for inputs used in measuring fair value that prioritize the use of observable inputs over the use of unobservable inputs, when such observable inputs are available. The three levels of inputs that may be used to measure fair value are as follows:


•	Level 1 - Quoted prices in active markets for identical assets or liabilities.


•	Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data.


•	Level 3 - Fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including assumptions and judgments made by the Company.

Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the observable inputs may result in a reclassification of assets and liabilities within the three levels of the hierarchy outlined above.

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

The Company measures certain assets and liabilities at fair value on a recurring basis such as our financial instruments, marketable securities and contingent consideration related to business combinations and recognizes transfers within the fair value hierarchy at the end of the fiscal quarter in which the change in circumstances that caused the transfer occurred. There have been no transfers between Level 1, 2 or 3 assets or liabilities during the fiscal year ended September 28, 2012 .

Due to the illiquid markets for the Company's ARS, these securities are appropriately classified as a Level 3 asset.

The Company has classified its contingent consideration, which was primarily related to the acquisition of SiGe Semiconductor Inc. ("SiGe") in fiscal 2011, as a Level 3 liability. The fair value of the contingent consideration liabilities were primarily computed based on expected revenue to be generated by the acquired enterprises using a weighted probability income approach. Revenue and other assumptions used in the calculation require significant management judgment. Accordingly, the contingent consideration liabilities were classified as Level 3. The Company reassessed the fair value of the contingent consideration liabilities on a quarterly basis. Based on that assessment, the Company recognized a reduction of approximately $5.4 million related to the actual calculation of the earn-out obligations during the fiscal year ended September 28, 2012 . The resulting gain was recorded in the selling, general and administrative line item on the Consolidated Statement of Operations. The Company paid $52.9 million in cash during the fourth fiscal quarter to settle the contingent consideration liability associated with the acquisition of SiGe.

Goodwill recognized through business combinations (Note 3)	133,958
Goodwill adjustments	3,514
Goodwill as of September 28, 2012	$	800,513

The increase in goodwill for the fiscal year ended September 28, 2012 resulted primarily from the acquisition of AATI as discussed in Note 3, Business Combinations in these Notes to the Consolidated Financial Statements. In addition, the Company recorded the final measurement period adjustment related to the acquisition of SiGe which resulted in an increase to goodwill.

The Company tests its goodwill and non-amortizing trademarks for impairment annually as of the first day of its fourth fiscal quarter and in interim periods if certain events occur indicating the carrying value of goodwill or non-amortizing trademarks may be impaired. There were no indicators of impairment noted during the fiscal year ended September 28, 2012 . However, based on the results of our annual testing, the Company determined that one of its non-amortizing trademarks did in fact have a finite life and accordingly the asset was reclassified and will be amortized over its estimated useful life as of September 28, 2012.

9. BORROWING ARRANGEMENTS

On March 2, 2007, the Company issued $200.0 million aggregate principal amount of convertible subordinated notes ("2007 Convertible Notes"). The offering contained two tranches. The first tranche consisted of $100.0 million of 1.25% convertible subordinated notes due March 2010 (the "1.25% Notes") which have been retired. The second tranche consisted of $100.0 million aggregate principal amount of 1.50% convertible subordinated notes due March 2012 (the "1.50% Notes"). During the fiscal year ended September 28, 2012 , the Company redeemed and retired the remaining $26.7 million of aggregate principal amount of the 1.50% Notes, paying a cash premium of $21.3 million which was accounted for as a reacquisition of equity instruments in accordance with ASC 470-20 - Debt, Debt with Conversions and Other Options .

The Company operates in foreign jurisdictions with income tax rates lower than the United States tax rate of 35% . The Company's tax benefits related to foreign earnings taxed at a rate less than the United States federal rate were $44.7 million and $24.4 million as of September 28, 2012 and September 30, 2011, respectively.

On October 2, 2010, the Company expanded its presence in Asia by launching operations in Singapore. The Company operates under a tax holiday in Singapore, which is effective through September 30, 2020. The tax holiday is conditional upon the Company's compliance in meeting certain employment and investment thresholds in Singapore. The impact of the tax holiday decreased Singapore's taxes by $5.9 million which resulted in a benefit of $0.03 of basic and diluted earnings per share for the fiscal year ended September 28, 2012. The impact of the tax holiday to fiscal 2011 was not material.

As a result of the enactment of the Tax Relief Act of 2010 which retroactively reinstated and extended the research and development tax credit, $6.2 million of federal research and development tax credits which were earned in fiscal year 2010 reduced our tax rate during the year ended September 30, 2011.

During fiscal year 2010, the Company restructured its international operations resulting in a tax benefit of $3.5 million . This consisted of a tax benefit of $6.3 million due to reassessing the United States income tax required to be recorded on earnings of our operations in Mexico, offset by $2.8 million of tax provision related to the transfer of assets to an affiliated foreign company. As a result of this restructuring, the Company is no longer required to assess United States income tax on the earnings of its Mexican business.

In accordance with GAAP, management has determined that it is more likely than not that a portion of its historic and current year income tax benefits will not be realized. As of September 28, 2012 , the Company has maintained a valuation allowance of $47.0 million . This valuation allowance is comprised of $33.6 million related to U.S. State tax credits, of which $3.6 million are state tax credits acquired from AATI in fiscal year 2012, and $13.4 million related to foreign deferred tax assets. If these benefits are recognized in a future period the valuation allowance on deferred tax assets will be reversed and up to a $46.6 million income tax benefit, and up to a $0.4 million reduction to goodwill may be recognized. The Company will need to generate $209.0 million of future United States federal taxable income to utilize our United States deferred tax assets as of September 28, 2012 .

Table of Contents

Deferred tax assets are recognized for foreign operations when management believes it is more likely than not that the deferred tax assets will be recovered during the carry forward period. The Company will continue to assess its valuation allowance in future periods.

As of September 28, 2012 , the Company has United States federal net operating loss carry forwards of approximately $74.3 million , including $29.5 million related to the acquisition of SiGe, which will expire at various dates through 2030 and $28.1 million related to the acquisition of AATI, which will expire at various dates through 2031 . The utilization of these net operating losses is subject to certain annual limitations as required under Internal Revenue Code section 382 and similar state income tax provisions. The Company also has United States federal income tax credit carry forwards of $37.8 million , of which $30.4 million of federal income tax credit carry forwards have not been recorded as a deferred tax asset. The Company also has state income tax credit carry forwards of $33.6 million , for which the Company has provided a valuation allowance. The United States federal tax credits expire at various dates through 2032 . The state tax credits relate primarily to California research tax credits which can be carried forward indefinitely.

The Company has continued to expand its operations and increase its investments in numerous international jurisdictions. These activities will increase the Company’s earnings attributable to foreign jurisdictions. As of September 28, 2012 , no provision has been made for United States federal, state, or additional foreign income taxes related to approximately $371.5 million of undistributed earnings of foreign subsidiaries which have been or are intended to be permanently reinvested. It is not practicable to determine the United States federal income tax liability, if any, which would be payable if such earnings were not permanently reinvested.

The Company’s gross unrecognized tax benefits totaled $52.4 million and $32.1 million as of September 28, 2012 and September 30, 2011 , respectively. Of the total unrecognized tax benefits at September 28, 2012 , $38.8 million would impact the effective tax rate, if recognized. The remaining unrecognized tax benefits would not impact the effective tax rate, if recognized, due to the Company’s valuation allowance and certain positions which were required to be capitalized. There are no positions which the Company anticipates could change within the next twelve months.

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows (in thousands):



	Unrecognized tax benefits
Balance at September 30, 2011	$	32,136
Increases based on positions related to prior years	9,004
Increases based on positions related to current year	11,265
Decreases relating to settlements with taxing authorities	—
Decreases relating to lapses of applicable statutes of limitations	(25		)
Balance at September 28, 2012	$	52,380

The current year increase in positions related to prior years of $9.0 million primarily includes $9.7 million of positions acquired from AATI during the fiscal year.

During the year ended September 28, 2012 , the Company did not recognize any significant amount of previously unrecognized tax benefits related to the expiration of the statute of limitations. The Company recognized $0.6 million of accrued interest or penalties related to unrecognized tax benefits during fiscal year 2012.

The Company’s major tax jurisdictions as of September 28, 2012 are the United States, California, Iowa, Singapore and Canada. For the United States, the Company has open tax years dating back to fiscal year 2002 due to the carry forward of tax attributes. For California and Iowa, the Company has open tax years dating back to fiscal year 2002 due to the carry forward of tax attributes. For Singapore, the Company has open tax years dating back to fiscal year 2011. For Canada, the Company has open tax years dating back to fiscal year 2004.

On August 3, 2010, the Board of Directors approved a stock repurchase program, pursuant to which the Company is authorized to repurchase up to $200.0 million of the Company's common stock from time to time on the open market or in privately negotiated transactions as permitted by securities laws and other legal requirements. During the fiscal year ended September 28, 2012 , the Company paid approximately $12.4 million (including commissions) in connection with the repurchase of 0.8 million shares of its common stock (paying an average price of $16.54 per share). This plan expired on August 3, 2012 and had $117.6 million remaining on the original amount.

On November 8, 2012 the Board of Directors approved a new share repurchase program, pursuant to which we are authorized to repurchase up to $200.0 million of our common stock from time to time on the open market or in privately negotiated transactions as permitted by securities laws and other legal requirements. The repurchase program is set to expire on November 8, 2014; however, it may be suspended, discontinued or extended at any time prior to November 8, 2014 upon approval of the Board of Directors. This repurchase program will be funded with our working capital.

The designation, powers, preferences, rights and qualifications, limitations and restrictions of the preferred stock of each series will be fixed by the certificate of designation relating to such series, which will specify the terms of the preferred stock. At September 28, 2012 , the Company had no shares of preferred stock issued or outstanding.

Table of Contents



	Fiscal Years Ended
	September 28, 2012		September 30, 2011		October 1, 2010
Expected volatility	59.21	%	49.26	%	56.19	%
Risk free interest rate (7 year contractual life options)	0.52	%	0.63	%	1.12	%
Dividend yield	0.00		0.00		0.00
Expected option life (7 year contractual life options)	4.09		4.10		4.23

The Company used an arithmetic average of historical volatility and implied volatility to calculate its expected volatility during the year ended September 28, 2012 . Historical volatility was determined by calculating the mean reversion of the weekly-adjusted closing stock price over the expected life of the options. The implied volatility was calculated by analyzing the 52-week minimum and maximum prices of publicly traded call options on the Company’s common stock. The Company concluded that an arithmetic average of these two calculations provided for the most reasonable estimate of expected volatility under the guidance of ASC 718.

The risk-free interest rate assumption is based upon observed Treasury bill interest rates appropriate for the expected life of the Company’s employee stock options.

The expected life of employee stock options represents a calculation based upon the historical exercise, cancellation and forfeiture experience for the Company across its demographic population. The Company believes that this historical data is the best estimate of the expected life of a new option and that generally all groups of the Company's employees exhibit similar behavior.

12. EMPLOYEE BENEFIT PLAN, PENSIONS AND OTHER RETIREE BENEFITS

The Company maintains the following pension and retiree benefit plans:


•	401(k) plan covering substantially all employees based in the United States


•	Pre-merger defined benefit pension plan covering certain former employees

Discretionary Company contributions are determined by the Board of Directors and may be in the form of cash or the Company’s stock. The Company has generally contributed a match of up to 4% of an employee’s contributed annual eligible compensation. For the fiscal years ended September 28, 2012 , September 30, 2011 , and October 1, 2010 , the Company contributed shares of 0.3 million , 0.2 million , and 0.3 million , respectively, and recognized expense of $6.0 million , $5.5 million , and $4.8 million , respectively.

14. CONTINGENCIES

Legal Matters

From time to time, various lawsuits, claims and proceedings have been, and may in the future be, instituted or asserted against the Company, including those pertaining to patent infringement, intellectual property, environmental, product liability and warranty, safety and health, employment and contractual matters.

Additionally, the semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark and other intellectual property rights to technologies that are important to the Company's business and have demanded and may in the future demand that the Company license their technology. The outcome of any such litigation cannot be predicted with certainty and some such lawsuits, claims or proceedings may be disposed of unfavorably to the Company. Generally speaking, intellectual property disputes often have a risk of injunctive relief, which, if imposed against the Company, could materially and adversely affect the Company's financial condition, or results of operations. From time to time the Company may also be involved in legal proceedings in the ordinary course of business. Legal costs are expensed as incurred.

On June 6 and 7, 2011, two putative stockholder class action lawsuits (Case No. 111CV202403 (the “Bushansky action”) and Case No. 111CV202501 (the “Venette action”), respectively) were filed in California Superior Court in Santa Clara County naming AATI, members of AATI's board of directors, the Company and PowerCo Acquisition Corp. (“Merger Sub”) as defendants. The lawsuits related to conduct surrounding the Company's acquisition of AATI. On July 26, 2011, the Court issued an order consolidating the Bushansky action and Venette action into a single, consolidated action captioned In re Advanced Analogic Technologies Inc. Shareholder Litigation, Lead Case No. 111CV202403, and designating an amended complaint filed on July 14, 2011 in the Venette action as the operative complaint in the litigation.

On November 30, 2011, following confidential arbitration proceedings in the Delaware Court of Chancery, the Company announced that it and AATI had amended their previously announced merger agreement whereby the Company would acquire AATI at a reduced price through a tender offer. The Company and AATI completed the transaction on January 9, 2012. On March 2, 2012, the Court stayed all discovery in the matter and ordered that Plaintiffs file an amended complaint by April 20, 2012.

On April 20, 2012, Plaintiffs filed an amended complaint (“First Amended Complaint”) against each of the original defendants with the exception of Merger Sub. The First Amended Complaint alleges, among other things, that (1) members of AATI's board of directors breached their fiduciary duties by (a) failing to take steps to maximize the value of AATI to its public shareholders by failing to adequately consider potential acquirers, (b) agreeing to the merger for inadequate consideration on unfair terms; (c) causing the filing of a materially misleading Schedule 14D-9 that failed to (i) disclose a basis for the price reduction, (ii) describe the arbitration proceedings, and (iii) include any financial valuation or fairness opinion concerning whether the revised merger consideration was fair; and (d) causing the issuance of amendments to the Schedule 14D-9 that failed to respond adequately to the SEC's disclosure directives; and (2) Skyworks and AATI allegedly aided and abetted these purported breaches of fiduciary duties. On June 22, 2012, the defendants filed demurrers to the First Amended Complaint. The Court will hold a hearing on those demurrers on December 7, 2012.

The Company monitors the status of these and other contingencies on an ongoing basis to ensure amounts are recognized and/or disclosed in our financial statements and footnotes as required by ASC 450, Loss Contingencies . At the time of this filing, the Company had not recorded any accrual for loss contingencies associated with its legal proceedings as losses resulting from such matters were determined not to be probable. In addition, the Company does not believe there are any legal proceedings that are

Table of Contents

reasonably possible to result in a material loss. We are engaged in various other legal actions, not described above, in the normal course of business and, while there can be no assurances, the Company believes the outcome of all pending litigation involving the Company will not have, individually or in the aggregate, a material adverse effect on our business.

15. GUARANTEES AND INDEMNITIES

The Company has made no contractual guarantees for the benefit of third parties. However, the Company generally indemnifies its customers from third-party intellectual property infringement litigation claims related to its products, and, on occasion, also provides other indemnities related to product sales. In connection with certain facility leases, the Company has indemnified its lessors for certain claims arising from the facility or the lease.

The Company indemnifies its directors and officers to the maximum extent permitted under the laws of the state of Delaware. The duration of the indemnities varies, and in many cases is indefinite. The indemnities to customers in connection with product sales generally are subject to limits based upon the amount of the related product sales and in many cases are subject to geographic and other restrictions. In certain instances, the Company's indemnities do not provide for any limitation of the maximum potential future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities in the accompanying consolidated balance sheets and does not expect that such obligations will have a material adverse impact on its financial condition or results of operations.

Equity based awards exercisable for approximately 4.0 million , 2.0 million , and 4.6 million shares were outstanding but not included in the computation of earnings per share for the fiscal year ended September 28, 2012 , September 30, 2011 and October 1, 2010 , respectively, as their effect would have been anti-dilutive.

18. SEGMENT INFORMATION AND CONCENTRATIONS

In accordance with ASC 280- Segment Reporting ("ASC 280"), the Company has one reportable operating segment which designs, develops, manufactures and markets proprietary semiconductor products, including intellectual property. ASC 280 establishes standards for the way public business enterprises report information about operating segments in annual financial statements and in interim reports to shareholders. The method for determining what information to report is based on management's use of financial information for the purposes of assessing performance and making operating decisions. In evaluating financial performance and making operating decisions, management primarily uses consolidated net revenue, gross profit, operating profit and earnings per share. The Company's business units share similar economic characteristics, long term business models, research and development expenses and selling, general and administrative expenses. In light of the recent acquisition of AATI, the Company reassessed its operations and concluded that there have been no changes and the Company continues to consider itself to have one reportable operating segment at September 28, 2012. The Company will re-assess its conclusions at least annually.

CONCENTRATIONS

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade accounts receivable. Trade accounts receivables are primarily derived from sales to manufacturers of communications and consumer products and electronic component distributors. Ongoing credit evaluations of customers’ financial condition are performed and collateral, such as letters of credit and bank guarantees, are required whenever deemed necessary.

In fiscal year 2012 the Company had two customers, Foxconn Technology Group ("Foxconn") and Samsung Electronics, each of which accounted for greater than 10% of our net revenue. In both fiscal year 2011 and 2010, the Company had three customers, each with greater than ten percent of net revenue: Foxconn, Nokia and Samsung Electronics.

The Company's greater than ten percent customers comprised the following percentages of net revenue:

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of disclosure controls and procedures.

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 28, 2012 . The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on management’s evaluation of our disclosure controls and procedures as of September 28, 2012 , our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in internal controls over financial reporting.

There are no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the period covered by this report that have materially affected or are reasonable likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:


•	Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;


•	Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and


•	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. 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.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of September 28, 2012 . In making this assessment, the Company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

Based on their assessment, management concluded that, as of September 28, 2012 , the Company’s internal control over financial reporting is effective based on those criteria.

In making this assessment, management has excluded the internal controls over financial reporting for the acquisition during the period, of Advanced Analogic Technologies, Inc. which was acquired on January 9, 2012 whose financial statements constitute approximately 13.7% of total consolidated assets (of which 8.1% represents goodwill and intangible assets included within the scope of the assessment) as of September 28, 2012 .

The Company’s independent registered public accounting firm has issued an audit report on the effectiveness of the Company’s internal control over financial reporting as stated within their report which appears herein.
