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.

5

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:

6

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.

7

Generating Superior Operating Results and Shareholder Returns

We seek to generate financial returns that are comparable to a highly diversified analog semiconductor company while delivering growth rates representative of a mobile internet company.  Given our business mix, volume and utilization we strive to achieve a best in-class return on investment and operating income to reward shareholders with increasing returns.

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

9

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

11

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,

12

• 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,

13

• 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,

14

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.

15

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 salescould 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

16

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.

17

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,

18

• 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

19

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

20

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,

21

•     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

22

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.

BASIS OF PRESENTATION

Our fiscal year ends on the Friday closest to September 30 of each year. 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.

The results of operations, assets and liabilities associated with the acquisition of Advanced Analogic Technologies Inc. ("AATI") completed during the fiscal year ended September 28, 2012 have been included in the consolidated statements of operations from the acquisition date (January 9, 2012) and are reflected in the balance sheet as of September 28, 2012. AATI's contribution to our consolidated results of operations for the fiscal year ended September 28, 2012 was insignificant. The transaction costs associated

25

with the AATI acquisition are included within selling, general and administrative expenses for the fiscal year ended September 28, 2012.

RESULTS OF OPERATIONS

FISCAL YEARS ENDED SEPTEMBER 28, 2012, SEPTEMBER 30, 2011, AND OCTOBER 1, 2010.

The following table sets forth the results of our operations expressed as a percentage of net revenue for the fiscal years below:

	2012		2011		2010
Net revenue	100.0	%	100.0	%	100.0	%

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.

For information regarding net revenue by geographic region and customer concentration, see Note 18 of Item 8 of this Annual Report on Form 10-K.

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.

27

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

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.

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.

_________________________

(1) Does not include restricted cash balances

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.

29

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).

(1) Other long-term liabilities include our gross unrecognized tax benefits, as well as executive deferred compensation which are both classified as beyond five years due to the uncertain nature of the liabilities.

(2) Other commitments consist of contractual license and royalty payments, and other purchase obligations. See Notes 13 of Item 8 of this Annual Report on Form 10-K

(3) Contingent consideration related to business combinations is recorded at fair value and actual results could differ. See Note 5 of Item 8 of this Annual Report on Form 10-K for further detail.

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

31

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.

32

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

33

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.

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

41

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

42

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.

43

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

44

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
Balance as of October 1, 2010	(385	)	(912	)	(1,297	)
Period adjustments	(34	)	—		(34	)
Balance as of September 30, 2011	(419	)	(912	)	(1,331	)
Period adjustments	(256	)	(6	)	(262	)
Balance as of September 28, 2012	(675	)	(918	)	(1,593	)

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.

45

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):

46

	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):

	Fiscal Year-Ended
	September 28, 2012		September 30, 2011
Revenue	$	1,585,022	$	1,509,709
Net income	$	218,364	$	177,443
Diluted earnings per common share	$	1.14	$	0.93

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.

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company's non-financial assets and liabilities, such as goodwill, intangible assets, and other long lived assets resulting from business combinations are measured at fair value using income approach valuation methodologies at the date of acquisition and subsequently re-measured if there are indicators of impairment. There were no indicators of impairment identified during the fiscal year ended September 28, 2012.

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.

Intangible assets consist of the following (in thousands):

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 endedSeptember 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.

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, 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.

52

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.

Deferred income tax assets and liabilities consist of the tax effects of temporary differences related to the following (in thousands):

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.

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.

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.

58

	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

401(k) Plan:

The Company maintains a 401(k) plan covering substantially all of its employees based in the United States under which all employees at least 21 years old are eligible to receive discretionary Company contributions. 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

60

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.

16.     RESTRUCTURING AND OTHER CHARGES

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.

The Company’s revenues by geography do not necessarily correlate to end market demand by region. For example, if the Company sells a power amplifier module to a customer in South Korea, the sale is recorded within the South Korea account although that customer, in turn, may integrate that module into a product sold to an end customer in a different geography.

Net property, plant and equipment balances, based on the physical locations within the indicated geographic areas are as follows (in thousands):

	As of

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:

	Fiscal Years Ended
	September 28, 2012	September 30, 2011	October 1, 2010
Company A	29%	27%	13%
Company B	17%	11%	13%
Company C	*	13%	12%

63

* Customer did not represent greater than ten percent of net revenue

At September 28, 2012, the Company's three largest accounts receivable balances comprised 60% of aggregate gross accounts receivable. This concentration was 53% and 60% at September 30, 2011 and October 1, 2010, respectively.

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.

(ii) If the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not reported, its Fair Market Value shall be the mean between the high bid and low asked prices for the Common Stock on the last market trading day prior to the day of determination; or

(iii) In the absence of an established market for the Common Stock, the Fair Market Value thereof shall be determined in good faith by the Administrator.

(m) “Incentive Stock Option” means an Option intended to qualify as an incentive stock option within the meaning of Section 422 of the Code.

3. Stock Subject to the Plan. Subject to the provisions of Section 12 of the Plan, the maximum aggregate number of Shares which may be subject to option and sold under the Plan is 22,278,581 Shares. The Shares may be authorized but unissued, or reacquired Common Stock.

If an Option or Stock Purchase Right expires or becomes unexercisable without having been exercised in full, or is surrendered pursuant to an Option Exchange Program, the unpurchased Shares which were subject thereto shall become available for future grant or sale under the Plan (unless the Plan has terminated). However, Shares that have actually been issued under the Plan, upon exercise of either an Option or Stock Purchase Right, shall not be returned to the Plan and shall not become available for future distribution under the Plan, except that if Shares of Restricted Stock are repurchased by the Company at their original purchase price, such Shares shall become available for future grant under the Plan.

4. Administration of the Plan.

(a) The Plan shall be administered by the Board or a Committee appointed by the Board, which Committee shall be constituted to comply with Applicable Laws.

(b) Powers of the Administrator. Subject to the provisions of the Plan and, in the case of a Committee, the specific duties delegated by the Board to such Committee, and subject to the approval of any relevant authorities, the Administrator shall have the authority in its discretion:

(i) to determine the Fair Market Value;

(ii) to select the Service Providers to whom Options and Stock Purchase Rights may from time to time be granted hereunder;

(iii) to determine the number of Shares to be covered by each such award granted hereunder;

(iv) to approve forms of agreement for use under the Plan;

(v) to determine the terms and conditions, of any Option or Stock Purchase Right granted hereunder. Such terms and conditions include, but are not limited to, the exercise price, the time or times when Options or Stock Purchase Rights may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Option or Stock Purchase Right or the Common Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine;

(vi) to determine whether and under what circumstances an Option may be settled in cash under subsection 9(f) instead of Common Stock;

(vii) to reduce the exercise price of any Option to the then current Fair Market Value if the Fair Market Value of the Common Stock covered by such Option has declined since the date the Option was granted;

(viii) to initiate an Option Exchange Program;

(ix) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred tax treatment under foreign tax laws;

(x) to allow Optionees to satisfy withholding tax obligations by electing to have the Company withhold from the Shares to be issued upon exercise of an Option or Stock Purchase Right that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by Optionees to have Shares withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable; and

(xi) to construe and interpret the terms of the Plan and awards granted pursuant to the Plan.

(c) Effect of Administrator’s Decision. All decisions, determinations and interpretations of the Administrator shall be final and binding on all Optionees.

5. Eligibility.

(a) Nonstatutory Stock Options and Stock Purchase Rights may be granted to Service Providers. Incentive Stock Options may be granted only to Employees.

(b) Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Optionee

during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(b), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted.

(c) Neither the Plan nor any Option or Stock Purchase Right shall confer upon any Optionee any right with respect to continuing the Optionee’s relationship as a Service Provider with the Company, nor shall it interfere in any way with his or her right or the Company’s right to terminate such relationship at any time, with or without cause.

6. Term of Plan. The Plan shall become effective upon its adoption by the Board. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 14 of the Plan.

7. Term of Option. The term of each Option shall be stated in the Option Agreement; provided, however, that the term shall be no more than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to an Optionee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant or such shorter term as may be provided in the Option Agreement.

8. Option Exercise Price and Consideration.

(a) The per share exercise price for the Shares to be issued upon exercise of an Option shall be such price as is determined by the Administrator, but shall be subject to the following:

(i) In the case of an Incentive Stock Option

(A) granted to an Employee who, at the time of grant of such Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant.

(B) granted to any other Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant.

(ii) In the case of a Nonstatutory Stock Option

(A) granted to a Service Provider who, at the time of grant of such Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of the grant.

(B) granted to any other Service Provider, the per Share exercise price shall be no less than 85% of the Fair Market Value per Share on the date of grant.

(iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price other than as required above pursuant to a merger or other corporate transaction.

(b) The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant). Such consideration may consist of (1) cash, (2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares acquired upon exercise of an Option, have been owned by the Optionee for more than six months on the date of surrender, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option shall be exercised, (5) consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan, or (6) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company.

9. Exercise of Option.

(a) Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be exercisable according to the terms hereof at such times and under such conditions as determined by the Administrator and set forth in the Option Agreement, but in no case at a rate of less than 20% per year over five (5) years from the date the Option is granted. Unless the Administrator provides otherwise, vesting of Options granted hereunder shall be tolled during any unpaid leave of absence. An Option may not be exercised for a fraction of a Share.

An Option shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the name of the Optionee and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Shares, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 12 of the Plan.

Exercise of an Option in any manner shall result in a decrease in the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(b) Termination of Relationship as a Service Provider. If an Optionee ceases to be a Service Provider, such Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement (of at least thirty (30) days) to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of the Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three (3) months following the Optionee’s termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(c) Disability of Optionee. If an Optionee ceases to be a Service Provider as a result of the Optionee’s Disability, the Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee’s termination. If such disability is not a “disability” as such term is defined in Section 22(e)(3) of the Code, in the case of an Incentive Stock Option such Incentive Stock Option shall automatically cease to be treated as an Incentive

Stock Option and shall be treated for tax purposes as a Nonstatutory Stock Option on the day three months and one day following such termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(d) Death of Optionee. If an Optionee dies while a Service Provider, the Option may be exercised within such period of time as is specified in the Option Agreement (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant), by the Optionee’s estate or by a person who acquires the right to exercise the Option by bequest or inheritance, but only to the extent that the Option is vested on the date of death. In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee’s termination. If, at the time of death, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall immediately revert to the Plan. The Option may be exercised by the executor or administrator of the Optionee’s estate or, if none, by the person(s) entitled to

exercise the Option under the Optionee’s will or the laws of descent or distribution. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(e) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares, an Option previously granted, based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made.

10. Non-Transferability of Options and Stock Purchase Rights. Options and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee.

11. Stock Purchase Rights.

(a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically of the terms, conditions and restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such offer. The terms of the offer shall comply in all respects with Section 260.140.42 of Title 10 of the California Code of Regulations. The offer shall be accepted by execution of a Restricted Stock purchase agreement in the form determined by the Administrator.

(b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock purchase agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or disability). The purchase price for Shares repurchased pursuant to the Restricted Stock purchase agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Administrator may determine, but in no case at a rate of less than 20% per year over five years from the date of purchase.

(c) Other Provisions. The Restricted Stock purchase agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion.

(d) Rights as a Shareholder. Once the Stock Purchase Right is exercised, the purchaser shall have rights equivalent to those of a shareholder and shall be a shareholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 12 of the Plan.

12. Adjustments Upon Changes in Capitalization, Merger or Asset Sale.

(a) Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option or Stock Purchase Right, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options or Stock Purchase Rights have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option or Stock Purchase Right, as well as the price per share of Common Stock covered by each such outstanding Option or Stock Purchase Right, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company. The conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or

securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option or Stock Purchase Right.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for an Optionee to have the right to exercise his or her Option until fifteen (15) days prior to such transaction as to all of the Optioned Stock covered thereby, including Shares as to which the Option would not otherwise be exercisable. In addition, the Administrator may provide that any Company repurchase option applicable to any Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse as to all such Shares, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised, an Option or Stock Purchase Right will terminate immediately prior to the consummation of such proposed action.

(c) Merger or Asset Sale. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the assets of the Company, each outstanding Option and Stock Purchase Right shall be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation.

In the event that the successor corporation refuses to assume or substitute for the Option or Stock Purchase Right, the Optionee shall fully vest in and have the right to exercise the Option or Stock Purchase Right as to all of the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable.

If an Option or Stock Purchase Right becomes fully vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Optionee in writing or electronically that the Option or Stock Purchase Right shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the Option or Stock Purchase Right shall terminate upon the expiration of such period.

For the purposes of this paragraph, the Option or Stock Purchase Right shall be considered assumed if, following the merger or sale of assets, the option or right confers the right to purchase or receive, for each Share of Optioned Stock subject to the Option or Stock Purchase Right immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or sale of assets is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option or Stock Purchase Right, for each Share of Optioned Stock subject to the Option or Stock Purchase Right, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger or sale of assets.

13. Time of Granting Options and Stock Purchase Rights. The date of grant of an Option or Stock Purchase Right shall, for all purposes, be the date on which the Administrator makes the determination granting such Option or Stock Purchase Right, or such other date as is determined by the Administrator. Notice of the determination shall be given to each Employee or Consultant to whom an Option or Stock Purchase Right is so granted within a reasonable time after the date of such grant.

14. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan.

(b) Shareholder Approval. The Board shall obtain shareholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

(c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the Company. Termination of

the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Options granted under the Plan prior to the date of such termination.

15. Conditions Upon Issuance of Shares.

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations. As a condition to the exercise of an Option, the Administrator may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

16. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

17. Reservation of Shares. The Company, during the term of this Plan, shall at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

18. Shareholder Approval. The Plan shall be subject to approval by the shareholders of the Company within twelve (12) months after the date the Plan is adopted. Such shareholder approval shall be obtained in the degree and manner required under Applicable Laws.

19. Information to Optionees and Purchasers. The Company shall provide to each Optionee and to each individual who acquires Shares pursuant to the Plan, not less frequently than annually during the period such Optionee or purchaser has one or more Options or Stock Purchase Rights outstanding, and, in the case of an individual who acquires Shares pursuant to the Plan, during the period such individual owns such Shares, copies of annual financial statements. The Company shall not be required to provide such statements to key employees whose duties in connection with the Company assure their access to equivalent information.

Unless otherwise defined herein, the terms defined in the Option Plan shall have the same defined meanings in this Option Agreement.

I.      NOTICE OF STOCK OPTION GRANT
Name:	«Optionee_Name»

The undersigned Optionee has been granted an Option to purchase Common Stock of the Company, subject to the terms and conditions of the Option Plan and this Option Agreement, as follows:

Date of Grant:
Vesting Commencement Date:	«VCD»
Exercise Price per Share:	$
Total Number of Shares Granted:	«No_of_Shares»
Total Exercise Price:	$«Exercise_Price»
Type of Option:	ISO
Term/Expiration Date:

Vesting Schedule:

This Option shall be exercisable, in whole or in part, according to the following vesting schedule:

One fourth (1/4^th) of the Shares subject to the Option shall vest one year after the Vesting Commencement Date, and an additional one fourth (1/4^th) of the Shares shall vest each one year thereafter, subject to Optionee’s continuing to be a Service Provider on such dates.

Termination Period:

This Option shall be exercisable for thirty (30) days after Optionee ceases to be a Service Provider. Upon Optionee’s death or disability, this Option may be exercised for such longer period as provided in the Option Plan. In no event may Optionee exercise this Option after the Term/Expiration Date as provided above.

II. AGREEMENT

1. Grant of Option. The Option Plan Administrator of the Company hereby grants to the Optionee named in the Notice of Grant (the “Optionee”), an option (the “Option”) to purchase the number of Shares set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), and subject to

the terms and conditions of the Option Plan, which is incorporated herein by reference. In the event of a conflict between the terms and conditions of the Option Plan and this Option Agreement, the terms and conditions of the Option Plan shall prevail.

If designated in the Notice of Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”).

2. Exercise of Option.

(a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Grant and with the applicable provisions of the Option Plan and this Option Agreement.

(b) Method of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) which shall state the election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price.

No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise complies with applicable laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the Option is exercised with respect to such Shares.

3. Optionee’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended, at the time this Option is exercised, the Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit B.

4. Lock-Up Period. Optionee hereby agrees that, if so requested by the Company or any representative of the under-writers (the “Managing Underwriter”) in connection with any registration of the offering of any securities of the Company under the Securities Act, Optionee shall not sell or otherwise transfer any Shares or other securities of the Company during the 180-day period (or such other period as may be requested in writing by the Managing Underwriter and agreed to in writing by the Company) (the “Market Standoff Period”) following the effective date of a registration statement of the Company filed under the Securities Act. Such restriction shall apply only to the first registration statement of the Company to become effective under the Securities Act that includes securities to be sold on behalf of the Company to the public in an underwritten public offering under the Securities Act. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff Period.

5. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee:

(a) cash or check;

(b) consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Option Plan; or

(c) surrender of other Shares which, (i) in the case of Shares acquired upon exercise of an option, have been owned by the Optionee for more than six (6) months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares.

6. Restrictions on Exercise. This Option may not be exercised until such time as the Option Plan has been approved by the shareholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law.

7. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Option Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee.

8. Term of Option. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Option Plan and the terms of this Option.

9. Tax Consequences. Set forth below is a brief summary as of the date of this Option of some of the federal tax consequences of exercise of this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

(a) Exercise of ISO. If this Option qualifies as an ISO, there will be no regular federal income tax liability upon the exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as an adjustment to the alternative minimum tax for federal tax purposes and may subject the Optionee to the alternative minimum tax in the year of exercise.

(b) Exercise of ISO Following Disability. If the Optionee ceases to be an Employee as a result of a disability that is not a total and permanent disability as defined in Section 22(e)(3) of the Code, to the extent permitted on the date of termination, the Optionee must exercise an ISO within three months of such termination for the ISO to be qualified as an ISO.

(c) Exercise of Nonstatutory Stock Option. There may be a regular federal income tax liability upon the exercise of a Nonstatutory Stock Option. The Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. If Optionee is an Employee or a former Employee, the Company will be required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount in cash equal to a percentage of this compensation income at the time of exercise, and may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise.

(d) Disposition of Shares. In the case of an NSO, if Shares are held for at least one year, any gain realized on disposition of the Shares will be treated as long-term capital gain for federal income tax purposes. In the case of an ISO, if Shares transferred pursuant to the Option are held for at least one year after exercise and of at least two years after the Date of Grant, any gain realized on disposition of the Shares will also be treated as long-term capital gain for federal income tax purposes. If Shares purchased under an ISO are disposed of within one year after exercise or two years after the Date of Grant, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the difference between the Exercise Price and the lesser of (1) the Fair Market Value of the Shares on the date of exercise, or (2) the sale price of the Shares. Any additional gain will be taxed as capital gain, short-term or long-term depending on the period that the ISO Shares were held.

(e) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (1) the date two years after the Date of Grant, or (2) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that Optionee may be subject to income tax withholding by the Company on the compensation income recognized by the Optionee.

10. Entire Agreement; Governing Law. The Option Plan is incorporated herein by reference. The Option Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to

the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee. This agreement is governed by the internal substantive laws but not the choice of law rules of California.

11. No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

Optionee acknowledges receipt of a copy of the Option Plan and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Option Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Option Plan or this Option. Optionee further agrees to notify the Company upon any change in the residence address indicated below.

3. Representations of Optionee. Optionee acknowledges that Optionee has received, read and understood the Option Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions.

4. Rights as Shareholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be issued to the Optionee as soon as practicable after the Option is exercised. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance.

5. Company’s Right of First Refusal. Before any Shares held by Optionee or any transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section (the “Right of First Refusal”).

(a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder pro-poses to transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s).

(b) Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (c) below.

(c) Purchase Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith.

(d) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice.

(e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 120 days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section shall continue to apply to the Shares in the hands of such Pro-posed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred.

(f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section notwithstanding, the transfer of any or all of the Shares during the Optionee’s lifetime or on the Optionee’s death by will or intestacy to the Optionee’s immediate family or a trust for the benefit of the Optionee’s immediate family shall be exempt from the provisions of this Section. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this Section.

(g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the first sale of Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act of 1933, as amended.

6. Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s purchase or disposition of the Shares. Optionee represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the Company for any tax advice.

7. Restrictive Legends and Stop-Transfer Orders.

(a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES.

(b) Stop-Transfer Notices. Optionee agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

(c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as

owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

8. Successors and Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company.

INVESTMENT REPRESENTATION STATEMENT

OPTIONEE:
COMPANY:	ADVANCED ANALOGIC TECHNOLOGIES INCORPORATED
SECURITY:	COMMON STOCK
AMOUNT:
DATE:

In connection with the purchase of the above-listed Securities, the undersigned Optionee represents to the Company the following:

(a) Optionee is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”).

(b) Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection, Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the Securities unless they are registered or such registration is not required in the opinion of counsel satisfactory to the Company, a legend prohibiting their transfer without the consent of the Commissioner of Corporations of the State of California and any other legend required under applicable state securities laws.

(c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company, (3) the amount of Securities being sold during any three month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable.

In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately above.

(d) Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any such other registration exemption will be available in such event.

This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price.

No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the Option is exercised with respect to such Shares.

3. Optionee’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended, at the time this Option is exercised, the Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit B.

4. Lock-Up Period. Optionee hereby agrees that Optionee shall not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by Optionee (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of any registration statement of the Company filed under the Securities Act.

Optionee agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Optionee shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. Optionee agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by this Section.

5. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee:

(a) cash;

(b) check;

(c) consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan;

(d) surrender of other Shares which, (i) in the case of Shares acquired from the Company, either directly or indirectly, have been owned by the Optionee, and not subject to a substantial risk of forfeiture, for more than six (6) months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares.

6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the shareholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law.

7. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee.

8. Term of Option. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option.

9. Tax Obligations.

(a) Withholding Taxes. Optionee agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Optionee acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise.

(b) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (1) the date two years after the Date of Grant, and (2) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that Optionee may be subject to income tax withholding by the Company on the compensation income recognized by the Optionee.

10. Entire Agreement; Governing Law. The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee. This Agreement is governed by the internal substantive laws but not the choice of law rules of California.

11. No Guarantee of Continued Service. OPTIONEE AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

Optionee acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option.

2. Delivery of Payment. Optionee herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement, and any and all withholding taxes due in connection with the exercise of the Option.

3. Representations of Optionee. Optionee acknowledges that Optionee has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions.

4. Rights as Shareholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be issued to the Optionee as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance.

5. Company’s Right of First Refusal. Before any Shares held by Optionee or any transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section (the “Right of First Refusal”).

(a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s).

(b) Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (c) below.

(c) Purchase Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith.

(d) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination thereof within 30 days after receipt of the Notice or in the manner and at the times set forth in the Notice.

(e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 120 days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred.

(f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section notwithstanding, the transfer of any or all of the Shares during the Optionee’s lifetime or on the Optionee’s death by will or intestacy to the Optionee’s immediate family or a trust for the benefit of the Optionee’s immediate family shall be exempt from the provisions of this Section. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this Section.

(g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded.

6. Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s purchase or disposition of the Shares. Optionee represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the Company for any tax advice.

7. Restrictive Legends and Stop-Transfer Orders.

(a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR A PERIOD NOT TO EXCEED 180 DAYS FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER WITHOUT THE CONSENT OF THE COMPANY.

(b) Stop-Transfer Notices. Optionee agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

(c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon Optionee and his or her heirs, executors, administrators, successors and assigns.

9. Interpretation.

The resolution of such a dispute by the Administrator shall be final and binding on all parties.

10. Governing Law; Severability. This Exercise Notice is governed by the internal substantive laws, but not the choice of law rules, of California.

INVESTMENT REPRESENTATION STATEMENT

OPTIONEE	:
COMPANY	:
SECURITY	:	COMMON STOCK
AMOUNT	:
DATE	:

In connection with the purchase of the above-listed Securities, the undersigned Optionee represents to the Company the following:

(a) Optionee is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”).

(b) Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection, Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with any legend required under applicable state securities laws.

(c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company, (3) the amount of Securities being sold during any three month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable.

In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which

requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately above.

(d) Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any such other registration exemption will be available in such event.

Signature of Optionee:

ADVANCED ANALOGIC TECHNOLOGIES, INC.

1998 STOCK PLAN

RESTRICTED STOCK PURCHASE AGREEMENT

THIS AGREEMENT is made between (the “Purchaser”) and Advanced Analogic Technologies, Inc. (the “Company”) or its assignees of rights hereunder as of , .

Unless otherwise defined herein, the terms defined in the 1998 Stock Plan shall have the same defined meanings in this Agreement.

RECITALS

A. Pursuant to the exercise of the option granted to Purchaser under the Plan and pursuant to the Option Agreement dated by and between the Company and Purchaser with respect to such grant (the “Option”), which Plan and Option Agreement are hereby incorporated by reference, Purchaser has elected to purchase of those shares of Common Stock which have not become vested under the vesting schedule set forth in the Option Agreement (“Unvested Shares”). The Unvested Shares and the shares subject to the Option Agreement, which have become vested are sometimes collectively referred to herein as the “Shares.”

B. As required by the Option Agreement, as a condition to Purchaser’s election to exercise the option, Purchaser must execute this Agreement, which sets forth the rights and obligations of the parties with respect to Shares acquired upon exercise of the Option.

1. Repurchase Option.

(a) If Purchaser’s status as a Service Provider is terminated for any reason, including for death and Disability, the Company shall have the right and option for ninety (90) days from such date to purchase from Purchaser, or Purchaser’s personal representative, as the case may be, all of the Purchaser’s Unvested Shares as of the date of such termination at the price paid by the Purchaser for such Shares (the “Repurchase Option”).

(b) Upon the occurrence of such termination, the Company may exercise its Repurchase Option by delivering personally or by registered mail, to Purchaser (or his transferee or legal representative, as the case may be) with a copy to the escrow agent described in Section 2 below, a notice in writing indicating the Company’s intention to exercise the Repurchase Option AND, at the Company’s option, (i) by delivering to the Purchaser (or the Purchaser’s transferee or legal representative) a check in the amount of the aggregate repurchase price, or (ii) by the Company canceling an amount of the Purchaser’s indebtedness to the Company equal to the aggregate repurchase price, or (iii) by a combination of (i) and (ii) so that the combined payment and cancellation of indebtedness equals such aggregate repurchase price. Upon delivery of such notice and payment of the aggregate repurchase price in any of the ways described above, the Company shall become the legal and beneficial owner of the Unvested Shares being repurchased and the rights and interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of Unvested Shares being repurchased by the Company.

(c) Whenever the Company shall have the right to repurchase Unvested Shares hereunder, the Company may designate and assign one or more employees, officers, directors or shareholders of the Company or other persons or organizations to exercise all or a part of the Company’s Repurchase Option under this Agreement and purchase all or a part of such Unvested Shares.

(d) If the Company does not elect to exercise the Repurchase Option conferred above by giving the requisite notice within ninety (90) days following the termination, the Repurchase Option shall terminate.

(e) The Repurchase Option shall terminate in accordance with the vesting schedule contained in Purchaser’s Option Agreement.

2. Transferability of the Shares; Escrow.

(a) Purchaser hereby authorizes and directs the Secretary of the Company, or such other person designated by the Company, to transfer the Unvested Shares as to which the Repurchase Option has been exercised from Purchaser to the Company.

(b) To insure the availability for delivery of Purchaser’s Unvested Shares upon repurchase by the Company pursuant to the Repurchase Option under Section 1, Purchaser hereby appoints the Secretary, or any other person designated by the Company as escrow agent (the “Escrow Agent”), as its attorney-in-fact to sell, assign and transfer unto the Company, such Unvested Shares, if any, repurchased by the Company pursuant to the Repurchase Option and shall, upon execution of this Agreement, deliver and deposit with the Escrow Agent, the share certificates representing the Unvested Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit C-2. The Unvested Shares and stock assignment shall be held by the Escrow Agent in escrow, pursuant to the Joint Escrow Instructions of the Company and Purchaser attached as Exhibit C-3 hereto, until the Company exercises its Repurchase Option, until such Unvested Shares are vested, or until such time as this Agreement no longer is in effect. Upon vesting of the Unvested Shares, the Escrow Agent shall promptly deliver to the Purchaser the certificate or certificates representing such Shares in the Escrow Agent’s possession belonging to the Purchaser, and the Escrow Agent shall be discharged of all further obligations hereunder; provided, however, that the Escrow Agent shall nevertheless retain such certificate or certificates as Escrow Agent if so required pursuant to other restrictions imposed pursuant to this Agreement.

(c) The Company nor the Escrow Agent shall be liable for any act it may do or omit to do with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its judgment.

(d) Transfer or sale of the Shares is subject to restrictions on transfer imposed by any applicable state and federal securities laws. Any transferee shall hold such Shares subject to all the provisions hereof and the Exercise Notice executed by the Purchaser with respect to any Unvested Shares purchased by Purchaser and shall acknowledge the same by signing a copy of this Agreement.

3. Ownership, Voting Rights, Duties. This Agreement shall not affect in any way the ownership, voting rights or other rights or duties of Purchaser, except as specifically provided herein.

4. Legends. The share certificate evidencing the Shares issued hereunder shall be endorsed with the following legend (in addition to any legend required under applicable federal and state securities laws):

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

5. Adjustment for Stock Split. All references to the number of Shares and the purchase price of the Shares in this Agreement shall be appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares, which may be made by the Company pursuant to the Plan after the date of this Agreement.

6. Notices. Notices required hereunder shall be given in person or by registered mail to the address of Purchaser shown on the records of the Company, and to the Company at their respective principal executive offices.

7. Survival of Terms. This Agreement shall apply to and bind Purchaser and the Company and their respective permitted assignees and transferees, heirs, legatees, executors, administrators and legal successors.

8. Section 83(b) Election. Purchaser hereby acknowledges that he or she has been informed that, with respect to the exercise of an Option for Unvested Shares, an election (the “Election”) may be filed by the Purchaser with the Internal Revenue Service, within thirty (30) days of the purchase of the exercised Shares, electing pursuant to

Section 83(b) of the Code to be taxed currently on any difference between the purchase price of the exercised Shares and their Fair Market Value on the date of purchase. In the case of a Nonstatutory Stock Option, this will result in a recognition of taxable income to the Purchaser on the date of exercise, measured by the excess, if any, of the Fair Market Value of the exercised Shares, at the time the Option is exercised over the purchase price for the exercised Shares. Absent such an Election, taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. In the case of an Incentive Stock Option, such an Election will result in a recognition of income to the Purchaser for alternative minimum tax purposes on the date of exercise, measured by the excess, if any, of the Fair Market Value of the exercised Shares, at the time the option is exercised, over the purchase price for the exercised Shares. Absent such an Election, alternative minimum taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. Purchaser is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing of the Election under Section 83(b) of the Code. A form of Election under Section 83(b) is attached hereto as Exhibit C-4 for reference.

PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER’S BEHALF.

9. Representations. Purchaser has reviewed with his own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement. Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Purchaser understands that he (and not the Company) shall be responsible for his own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

10. Governing Law. This Agreement shall be governed by the internal substantive laws, but not the choice of law rules, of California.

Purchaser represents that he has read this Agreement and is familiar with its terms and provisions. Purchaser hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under this Agreement.

IN WITNESS WHEREOF, this Agreement is deemed made as of the date first set forth above.

Dear :

As Escrow Agent for both Advanced Analogic Technologies, Inc.

1. In the event the Company and/or any assignee of the Company (referred to collectively for convenience herein as the “Company”) exercises the Company’s repurchase option set forth in the Agreement, the Company shall give to Purchaser and you a written notice specifying the number of shares of stock to be purchased, the purchase price, and the time for a closing hereunder at the principal office of the Company. Purchaser and the Company hereby irrevocably authorize and direct you to close the transaction contemplated by such notice in accordance with the terms of said notice.

2. At the closing, you are directed (a) to date the stock assignments necessary for the transfer in question, (b) to fill in the number of shares being transferred, and (c) to deliver the stock assignments, together with the certificate evidencing the shares of stock to be transferred, to the Company or its assignee, against the simultaneous delivery to you of the purchase price (by cash, a check, or some combination thereof) for the number of shares of stock being purchased pursuant to the exercise of the Company’s repurchase option.

3. Purchaser irrevocably authorizes the Company to deposit with you any certificates evidencing shares of stock to be held by you hereunder and any additions and substitutions to said shares as defined in the Agreement.

3. Stock Subject to the Plan.

(a) Stock Subject to the Plan. Subject to the provisions of Section 14 of the Plan, the maximum aggregate number of Shares that may be optioned and sold under the Plan is 9,000,000 Shares plus the number of Shares which have been reserved but not issued under the Company’s 1998 Stock Plan (the “1998 Plan”) as of the Registration Date, (ii) any Shares returned to the 1998 Plan as a result of termination of options or repurchase of Shares issued under such plan, and (iii) an annual increase to be added on the first day of the Company’s fiscal year beginning with the Company’s 2006 fiscal year, equal to the least of (A) 4,000,000 Shares, (B) 3% of

the outstanding Shares on such date or (C) an amount determined by the Board. The Shares may be authorized, but unissued, or reacquired Common Stock.

(b) Lapsed Awards. If an Award expires or becomes unexercisable without having been exercised in full, is surrendered pursuant to an Exchange Program, or, with respect to Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units, is forfeited to or repurchased by the Company, the unpurchased Shares (or for Awards other than Options and SARs, the forfeited or repurchased Shares) which were subject thereto will become available for future grant or sale under the Plan (unless the Plan has terminated). With respect to SARs, only Shares actually issued pursuant to an SAR will cease to be available under the Plan; all remaining Shares under SARs will remain available for future grant or sale under the Plan (unless the Plan has terminated). However, Shares that have actually been issued under the Plan under any Award will not be returned to the Plan and will not become available for future distribution under the Plan; provided, however, that if Shares of Restricted Stock, Performance Shares or Performance Units are repurchased by the Company or are forfeited to the Company, such Shares will become available for future grant under the Plan. Shares used to pay the tax and exercise price of an Award will become available for future grant or sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in reducing the number of Shares available for issuance under the Plan. Notwithstanding the foregoing and, subject to adjustment provided in Section 14, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options shall equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Section 422 of the Code, any Shares that become available for issuance under the Plan under this Section 3(b).

(c) Share Reserve. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan.

4. Administration of the Plan.

(a) Procedure.

(i) Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan.

(ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Options granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan will be administered by a Committee of two or more “outside directors” within the meaning of Section 162(m) of the Code.

(iii)       Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3.

(iv)      Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a Committee, which committee will be constituted to satisfy Applicable Laws.

(b) Powers of the Administrator. Subject to the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion:

(i)        to determine the Fair Market Value;

(ii)       to select the Service Providers to whom Awards may be granted hereunder;

(iii)      to determine the number of Shares to be covered by each Award granted hereunder;

(iv)      to approve forms of agreement for use under the Plan;

(v)       to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine;

(vi)      to institute an Exchange Program;

(vii)     to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan;

(viii)    to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of satisfying applicable foreign laws;

(ix)      to modify or amend each Award (subject to Section 19(c) of the Plan), including the discretionary authority to extend the post-termination exercisability period of Awards longer than is otherwise provided for in the Plan;

(x)       to allow Participants to satisfy withholding tax obligations in such manner as prescribed in Section 15;

(xi) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator;

(xii) to allow a Participant to defer the receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant under an Award;

(xiii) to make all other determinations deemed necessary or advisable for administering the Plan.

(c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of Awards.

5. Eligibility. Nonstatutory Stock Options, Restricted Stock, Restricted Stock Units, Stock Appreciation Rights, Performance Units and Performance Shares may be granted to Service Providers. Incentive Stock Options may be granted only to Employees.

6. Stock Options.

(a) Limitations.

(i) Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options will be taken into account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted.

(ii) The following limitations will apply to grants of Options:

(1) No Service Provider will be granted, in any Fiscal Year, Options to purchase more than 1,000,000 Shares.

(2) In connection with his or her initial service, a Service Provider may be granted Options to purchase up to an additional 1,000,000 Shares, which will not count against the limit set forth in Section 6(a)(2)(ii)(1) above.

(3) The foregoing limitations will be adjusted proportionately in connection with any change in the Company’s capitalization as described in Section 14.

(4) If an Option is cancelled in the same Fiscal Year in which it was granted (other than in connection with a transaction described in Section 14), the cancelled Option will be counted against the limits set forth in subsections (1) and (2) above. For this purpose, if the exercise price of an Option is reduced, the transaction will be treated as a cancellation of the Option and the grant of a new Option.

(b) Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive Stock Option, the term will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement.

(c) Option Exercise Price and Consideration.

(i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined by the Administrator, subject to the following:

(1) In the case of an Incentive Stock Option

a) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than 110% of the Fair Market Value per Share on the date of grant.

b) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price will be no less than 100% of the Fair Market Value per Share on the date of grant.

c) Notwithstanding the foregoing, Incentive Stock Options may be granted with a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code.

(2) In the case of a Nonstatutory Stock Option, the per Share exercise price will be determined by the Administrator. In the case of a Nonstatutory Stock Option intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, the per Share exercise price will be no less than 100% of the Fair Market Value per Share on the date of grant.

(ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised.

(iii) Form of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely of: (1) cash; (2) check; (3) promissory note; (4) other Shares, provided Shares acquired directly or indirectly from the Company, (A) have been owned by the Participant and not subject to substantial risk of forfeiture for more than six months on the date of surrender, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option will be exercised; (5) consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan; (6) a reduction in the amount of any Company liability to the Participant, including any liability attributable to the Participant’s participation in any Company-sponsored deferred compensation program or arrangement; (7) any combination of the foregoing methods of payment; or (8) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws.

(d) Exercise of Option.

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share.

An Option will be deemed exercised when the Company receives: (i) notice of exercise (in such form as the Administrator specify from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with an applicable withholding taxes). Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 14 of the Plan.

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s death or Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for three (3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

(iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised following the Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the option be exercised later than the expiration of the term of such Option as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided by the Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

7. Restricted Stock.

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine.

(b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted Stock until the restrictions on such Shares have lapsed.

(c) Transferability. Except as provided in this Section 7, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction.

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as it may deem advisable or appropriate.

(e) Removal of Restrictions. Except as otherwise provided in this Section 7, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may determine. The Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed.

(f) Voting Rights. During the Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise.

(g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be entitled to receive all dividends and other distributions paid with respect to such Shares unless otherwise provided in the Award Agreement. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid.

(h) Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan.

8. Restricted Stock Units.

(a) Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units under the Plan, it shall advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units and the form of payout, which, subject to Section 8(d), may be left to the discretion of the Administrator.

(b) Vesting Criteria and Other Terms. The Administrator shall set vesting criteria in its discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, continued employment), or any other basis determined by the Administrator in its discretion.

(c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant shall be entitled to receive a payout as specified in the Restricted Stock Unit Award Agreement. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a payout.

(d) Form and Timing of Payment. Payment of earned Restricted Stock Units shall be made as soon as practicable after the date(s) set forth in the Restricted Stock Unit Award Agreement. The Administrator, in its sole discretion, may pay earned Restricted Stock Units in cash, Shares, or a combination thereof. Shares represented by Restricted Stock Units that are fully paid in cash again shall be available for grant under the Plan.

(e) Cancellation. On the date set forth in the Restricted Stock Unit Award Agreement, all unearned Restricted Stock Units shall be forfeited to the Company.

9. Stock Appreciation Rights.

(a) Grant of SARs. Subject to the terms and conditions of the Plan, a SAR may be granted to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion.

(b) Number of Shares. The Administrator will have complete discretion to determine the number of SARs granted to any Service Provider.

(c) Exercise Price and Other Terms. The Administrator, subject to the provisions of the Plan, will have complete discretion to determine the terms and conditions of SARs granted under the Plan.

(d) SAR Agreement. Each SAR grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the SAR, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine.

(e) Expiration of SARs. An SAR granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(d) also will apply to SARs.

(f) Payment of SAR Amount. Upon exercise of an SAR, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying:

(i) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times

(ii) The number of Shares with respect to which the SAR is exercised.

At the discretion of the Administrator, the payment upon SAR exercise may be in cash, in Shares of equivalent value, or in some combination thereof.

10. Performance Units and Performance Shares.

(a) Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service Providers at any time and from time to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete discretion in determining the number of Performance Units and Performance Shares granted to each Participant.

(b) Value of Performance Units/Shares. Each Performance Unit will have an initial value that is established by the Administrator on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant.

(c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (including, without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the Service

Providers. The time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” Each Award of Performance Units/Shares will be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, or individual goals, applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion.

(d) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares will be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives or other vesting provisions have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such Performance Unit/Share.

(e) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made as soon as practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof.

(f) Cancellation of Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan.

11. Formula Option Grants to Outside Directors.

(a) General. Outside Directors will be entitled to receive all types of Awards under this Plan, including discretionary Awards not covered under this Section 11. All grants of Options to Outside Directors pursuant to this Section will be automatic and nondiscretionary, except as otherwise provided herein, and will be made in accordance with the following provisions:

(b) Type of Option. All Options granted pursuant to this Section will be Nonstatutory Stock Options and, except as otherwise provided herein, will be subject to the other terms and conditions of the Plan.

(c) No Discretion. No person will have any discretion to select which Outside Directors will be granted Options under this Section or to determine the number of Shares to be covered by such Options (except as provided in Sections 11(g) and 14).

(d) Initial Option. Each person who first becomes an Outside Director following the Registration Date will be automatically granted an Option to purchase 20,000 Shares (the “Initial Option”) on or about the date on which such person first becomes an Outside Director, whether through election by the stockholders of the Company or appointment by the Board to fill a vacancy; provided, however, that an Inside Director who ceases to be an Inside Director, but who remains a Director, will not receive an Initial Option.

(e) Annual Option. Each Outside Director will be automatically granted an Option to purchase 5,000 Shares (an “Annual Option”) on each date of the annual meeting of the stockholders of the Company beginning in 2006, if as of such date, he or she will have served on the Board for at least the preceding six (6) months.

(f) Terms. The terms of each Option granted pursuant to this Section will be as follows:

(i)    The term of the Option will be ten (10) years.

(ii)   The exercise price per Share will be 100% of the Fair Market Value per Share on the date of grant of the Option.

(iii)  Subject to Section 14, the Initial Option will vest and become exercisable as to twenty-five percent (25%) of the Shares subject to such Option on each anniversary of its date of grant, provided that the Participant continues to serve as a Director through each such date.

(iv) Subject to Section 14, the Annual Option will vest and become exercisable as to 100% of the Shares subject to such Option on the one-year anniversary of its date of grant, provided that the Participant continues to serve as a Director through such date.

(g) Amendment. The Administrator in its discretion may change the number of Shares subject to the Initial Options and Annual Options.

12. Leaves of Absence. Unless the Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Service Provider will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then three (3) months following the 91^st day of such leave any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option.

13. Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, such Award will contain such additional terms and conditions as the Administrator deems appropriate.

14. Adjustments; Dissolution or Liquidation; Merger or Change in Control.

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, may (in its sole discretion) adjust the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award, the numerical Share limits in Sections 3 and 6 of the Plan and the number of Shares issuable pursuant to Options to be granted under Section 11.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action.

(c) Change in Control. In the event of a merger or Change in Control, each outstanding Award will be treated as the Administrator determines, including, without limitation, that each Award be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. The Administrator shall not be required to treat all Awards similarly in the transaction.

In the event that the successor corporation does not assume or substitute for the Award, unless the Administrator provides otherwise, the Participant will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock

and Restricted Stock Units will lapse, and, with respect to Performance Shares and Performance Units, all Performance Goals or other vesting criteria will be deemed achieved at target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period.

For the purposes of this subsection (c), an Award will be considered assumed if, following the Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) or, in the case of a Stock Appreciation Right upon the exercise of which the Administrator determines to pay cash or a Performance Share or Performance Unit which the Administrator can determine to pay in cash, the fair market value of the consideration received in the merger or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Share or Performance Unit, for each Share subject to such Award (or in the case of Restricted Stock Units and Performance Units, the number of implied shares determined by dividing the value of the Restricted Stock Units and Performance Units, as applicable, by the per share consideration received by holders of Common Stock in the Change in Control), to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the Change in Control.

Notwithstanding anything in this Section 14(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s consent; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption.

(d) Termination Following Change of Control. With respect to Awards granted to an Outside Director that are assumed or substituted for, if on the date of or following such assumption or substitution the Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant, then the Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Optioned Stock, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Performance Shares and Performance Units, all performance goals or other vesting criteria will be deemed achieved at target levels and all other terms and conditions met.

15. Tax Withholding.

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof), the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise thereof).

(b) Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (a) paying cash, (b) electing to have the Company withhold otherwise deliverable cash or Shares having a Fair Market Value equal to the minimum amount required to be withheld, or (c) delivering to the Company already-owned Shares having a Fair Market Value equal to the minimum amount required to be withheld. The amount of the withholding requirement will be deemed to include any amount which the Administrator agrees may be withheld at the time the election is made, not to exceed the amount determined by using the maximum federal, state or local marginal income tax rates applicable to the Participant with respect to the Award on the date that the amount of tax to be withheld is to be determined. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld.

16. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company, nor will they interfere in any way with the Participant’s right or the Company’s right to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws.

17. Date of Grant. The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time after the date of such grant.

18. Term of Plan. Subject to Section 22 of the Plan, the Plan will become effective upon its adoption by the Board. It will continue in effect for a term of ten (10) years unless terminated earlier under Section 19 of the Plan.

19. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan.

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

(c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.

20. Conditions Upon Issuance of Shares.

(a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

21. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority will not have been obtained.

22. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.

II. AGREEMENT

A. Grant of Option.

The Administrator hereby grants to individual named in the Notice of Grant attached as Part I of this Agreement (the “Participant”) an option (the “Option”) to purchase the number of Shares, as set forth in the Notice of Grant, at the exercise price per share set forth in the Notice of Grant (the “Exercise Price”), subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Award Agreement, the terms and conditions of the Plan will prevail.

If designated in the Notice of Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option under Section 422 of the Code. However, if this Option is intended to be an Incentive Stock Option, to the extent that it exceeds the $100,000 rule of Code Section 422(d) it will be treated as a Nonstatutory Stock Option (“NSO”).

B. Exercise of Option.

(a) Right to Exercise. This Option is exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Grant and the applicable provisions of the Plan and this Award Agreement.

(b) Method of Exercise. This Option is exercisable by delivery of an exercise notice, in the form attached as Exhibit A (the “Exercise Notice”), which will state the election to exercise the Option, the number of Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan.

This Option will be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by such aggregate Exercise Price.

No Shares will be issued pursuant to the exercise of this Option unless such issuance and exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Exercised Shares will be considered transferred to Participant on the date the Option is exercised with respect to such Exercised Shares.

C. Method of Payment.

Payment of the aggregate Exercise Price will be by any of the following, or a combination thereof, at the election of Participant:

1. cash;

2. check;

3. consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or

4. surrender of other Shares which, (i) in the case of Shares acquired from the Company, either directly or indirectly, have been owned by the Participant and not subject to a substantial risk of forfeiture for more than six (6) months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares.

D. Non-Transferability of Option.

This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan and this Award Agreement will be binding upon the executors, administrators, heirs, successors and assigns of Participant.

E. Term of Option.

This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Award Agreement.

F. Tax Obligations.

1. Withholding Taxes. Participant agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or retaining Participant) for the satisfaction of all Federal, state, and local income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise.

2. Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (1) the date two years after the Grant Date, or (2) the date one year after the date of exercise, Participant will immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation income recognized by Participant.

G. Entire Agreement; Governing Law.

The Plan is incorporated herein by reference. The Plan and this Award Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to Participant’s interest except by means of a writing signed by the Company and Participant. This Award Agreement is governed by the internal substantive laws, but not the choice of law rules, of California.

H. NO GUARANTEE OF CONTINUED SERVICE.

PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS AN EMPLOYEE, CONSULTANT OR NON-EMPLOYEE DIRECTOR AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER).

Business Combinations [Abstract]

BUSINESS COMBINATIONS

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):

	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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 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 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.

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
Balance as of October 1, 2010	(385	)	(912	)	(1,297	)
Period adjustments	(34	)	—		(34	)
Balance as of September 30, 2011	(419	)	(912	)	(1,331	)
Period adjustments	(256	)	(6	)	(262	)
Balance as of September 28, 2012	(675	)	(918	)	(1,593	)

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.

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.

Segment Reporting [Abstract]

SEGMENT INFORMATION AND CONCENTRATIONS

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:

	Fiscal Years Ended
	September 28, 2012	September 30, 2011	October 1, 2010
Company A	29%	27%	13%
Company B	17%	11%	13%
Company C	*	13%	12%

* Customer did not represent greater than ten percent of net revenue

At September 28, 2012, the Company's three largest accounts receivable balances comprised 60% of aggregate gross accounts receivable. This concentration was 53% and 60% at September 30, 2011 and October 1, 2010, respectively.

STOCKHOLDERS’ EQUITY

STOCKHOLDERS’ EQUITY

COMMON STOCK

At September 28, 2012, the Company is authorized to issue 525 million shares of common stock, par value $0.25 per share of which 202,937,547 shares are issued and 192,296,130 shares outstanding.

Holders of the Company’s common stock are entitled to such dividends as may be declared by the Company’s Board of Directors out of funds legally available for such purpose. Dividends may not be paid on common stock unless all accrued dividends on preferred stock, if any, have been paid or declared and set aside. In the event of the Company’s liquidation, dissolution or winding up, the holders of common stock will be entitled to share pro rata in the assets remaining after payment to creditors and after payment of the liquidation preference plus any unpaid dividends to holders of any outstanding preferred stock.

Each holder of the Company’s common stock is entitled to one vote for each such share outstanding in the holder’s name. No holder of common stock is entitled to cumulate votes in voting for directors. The Company’s restated certificate of incorporation as amended to date, ("the Certificate of Incorporation") provides that, unless otherwise determined by the Company’s Board of Directors, no holder of stock has any preemptive right to purchase or subscribe for any stock of any class which the Company may issue or sell.

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.

PREFERRED STOCK

The Company’s Certificate of Incorporation has authorized and permits the Company to issue up to 25 million shares of preferred stock without par value in one or more series and with rights and preferences that may be fixed or designated by the Company’s Board of Directors without any further action by the Company’s stockholders. 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.

Under these plans, eligible employees may purchase common stock through payroll deductions of up to 10% of their compensation. The price per share is the lower of 85% of the fair market value of the common stock at the beginning or end of each offering period (generally six months). The plans provide for purchases by employees of up to an aggregate of 10.6 million shares through December 31, 2012. Shares of common stock purchased under these plans in fiscal years 2012, 2011, and 2010 were 0.5 million, 0.5 million, and 0.6 million, respectively.

The fair value of the restricted and performance awards is equal to the closing market price of the Company's common stock on the date of grant.

	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.

Fair Value Disclosures [Abstract]

FAIR VALUE

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.

As of September 28, 2012, assets and liabilities recorded at fair value on a recurring basis consist of the following (in thousands):                         

			Fair Value Measurements
	Total		Quoted prices in active markets for identical assets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company's non-financial assets and liabilities, such as goodwill, intangible assets, and other long lived assets resulting from business combinations are measured at fair value using income approach valuation methodologies at the date of acquisition and subsequently re-measured if there are indicators of impairment. There were no indicators of impairment identified during the fiscal year ended September 28, 2012.

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.

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.

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, 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.

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.

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.

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.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Sep. 28, 2012

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

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 Period, Policy [Policy Text Block]

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, Policy [Policy Text Block]

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, Policy [Policy Text Block]

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.

Premiums Receivable, Allowance for Doubtful Accounts, Estimation Methodology, Policy [Policy Text Block]

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 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, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

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.

Investment, Policy [Policy Text Block]

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.

Fair Value of Financial Instruments, Policy [Policy Text Block]

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, Policy [Policy Text Block]

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, Policy [Policy Text Block]

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.

Goodwill and Intangible Assets, Policy [Policy Text Block]

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 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 Policy [Policy Text Block]

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, Option and Incentive Plans Policy [Policy Text Block]

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.

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 Charges, Policy [Policy Text Block]

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.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

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 Tax, Policy [Policy Text Block]

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 Expense, Policy [Policy Text Block]

RESEARCH AND DEVELOPMENT COSTS

Research and development costs are expensed as incurred.

Commitments and Contingencies, Policy [Policy Text Block]

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.

Stockholders' Equity, Policy [Policy Text Block]

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.

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 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.
