INDUSTRY BACKGROUND
We believe there are several key growth trends shaping the wireless industry. First is the advent of the mobile Internet, where consumers are increasingly demanding mobile devices with faster data rates, advanced image quality and improved Internet connectivity. We believe that this demand is one of the biggest growth trends in technology.
On the high-end of the cellular handset market, smart phone growth - which is at the heart of the mobile Internet phenomenon - is fostering this industry-wide sea change. In effect, the smart phone is becoming an increasingly mainstream communication platform that is changing the way in which we live, work and play. Social media and social networking sites are only fueling this trend. Furthermore, this segment is being embraced and widely promoted by carriers who benefit from the highly profitable data services revenue stream as subscribers move to enhanced data plans.
The increased presence of multimedia-rich mobile devices has led manufacturers to recognize the increasingly important role multimode, multiband solutions play in the rapidly evolving wireless handset market, particularly as the industry migrates to 4G technologies which enable applications such as Web browsing, video streaming, gaming, MP3 players and cameras at higher speeds and data rates. Next-generation EDGE, WEDGE, WCDMA and LTE wireless platforms are now being used in the majority of the more than one and a half billion cellular phones the industry produces annually which results in increasing complexity in the RF module because each new wireless platform and operating frequency band requires additional amplifier, filtering and switching content to support:

• | backward compatibility to existing networks,

• | simultaneous transmission of voice and data,

• | international roaming, and

• | broadband functionality to accommodate music, video, data, and other multimedia features.

Further, given constraints on handset size and power consumption, these complex modules must remain physically small, energy efficient and cost effective, while also managing an unprecedented level of potential signal interference within the handset.
Finally, and a direct result of this increasing RF complexity, the addressable semiconductor content within the transmit and receive chain portion of the mobile device is increasing. We believe this trend is creating an incremental market opportunity measured in the billions of dollars as switching, filtering and wireless local area networking functionality are integrated.
Meanwhile, outside of the handset market, the proliferation of wireless technologies and our broadening footprint within analog semiconductor applications are increasing our market opportunity. According to Gartner, a leading independent market research firm, the total available market for the analog semiconductor segment is expected to exceed $18 billion in 2014. Today, the analog semiconductor market, which is characterized by longer product lifecycles and relatively high gross margins, is fragmented and diversified among various end-markets, customer bases and applications including:

• | Infrastructure

• | Automotive

• | CATV/Satcom

• | Smart Energy

• | Medical

• | Military

• | RFID

• | Test & Measurement

• | WiMAX

SKYWORKS’ STRATEGY
Skyworks' mission is to achieve mobile connectivity leadership through semiconductor innovation. Key elements in our strategy include:
Diversifying Our Business
By leveraging our core analog and mixed signal technology, Skyworks is able to deliver solutions to a broad and diverse set of end markets and customers. In the handset market, we currently support all top tier manufacturers including the leading smart phone suppliers, and have strategic relationships with each key baseband vendor. In high performance analog markets, we expect to continue to take advantage of our catalog business, intellectual property and worldwide distribution network, we plan to bolster our product pipeline and expand our addressable markets beyond the approximately 1,000 global customers and 2,500 analog components currently marketed.
Gaining Market Share
Our customer engagements are increasingly centered on solving highly complex multimode, multiband, switching, filtering, digital control and amplification challenges - system-level requirements which intersect with Skyworks' core competencies. Skyworks continues to invest in developing architectures that optimize power efficiency while minimizing cost and footprint, which we believe will allow us to meet our customers' demanding next-generation technology requirements, as well as stringent quality standards and high volume manufacturing capabilities.
Capitalizing on Content Growth in Third and Fourth Generation (3G and 4G) Mobile Communications Technologies
As the industry migrates to multimode, multiband EDGE, WEDGE, WCDMA and LTE architectures across a multitude of wireless broadband applications, RF complexity in the transmit and receive chain substantially increases given simultaneous voice and high speed data communications requirements, coupled with the need for backward compatibility to existing networks. As a result of this complexity in the RF module, we believe that our addressable market is increasing significantly.
Delivering Operational Excellence
Skyworks' strategy is to either vertically integrate our supply chain where we can create a competitive advantage or otherwise enter into alliances and strategic relationships for leading-edge capabilities. This hybrid manufacturing approach allows us to better balance external capacity with the demands of the marketplace. Internally, our capacity utilization remains high and we are therefore able to maintain margins and to achieve our desired return on invested capital on a broader range of revenue. We continue to focus on trying to achieve the industry's shortest product cycle times, highest yields and ultimately lowest product cost structure.

REVENUE FROM AND DEPENDENCE ON CUSTOMERS; CUSTOMER CONCENTRATION
For information regarding customer concentration and revenues from external customers, see Note 18 of 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 intellectual property, including patents, patent applications, trade secrets and trademarks are 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 proprietary 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 occasionally purchase intellectual property. Due to rapid technological changes in the industry, we believe that 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
We compete on the basis of time-to-market, new product innovation, overall product quality and performance, price, compliance with industry standards, strategic relationships with customers and baseband vendors, and protection of our intellectual property. 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.
RESEARCH AND DEVELOPMENT
Our products and markets are subject to continued technological advances. Recognizing the importance of such technological advances, we maintain a high level of research and development activities. We maintain close collaborative relationships with many of our customers to help identify market demands and target our development efforts to meet those demands. We focus our development efforts on new products, design tools and manufacturing leveraging our core technologies.

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 a limited number of long-term supply contracts with our suppliers. Certain of our suppliers consign raw materials to us at our manufacturing facilities. We request these raw materials and take title to them as they are 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 primarily pursuant to standard purchase orders 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 volumes 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 local and regional lead free and other “green” initiatives. 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. 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 cellular handsets. The highest demand for our handset products generally occurs in the calendar quarter ending in December. The lowest demand for our handset products generally occurs in the calendar quarter ending in March.
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. The majority of our tangible long lived assets are located in the United States of America and Mexico (see Note 18 of Item 8). Risks attendant to our foreign operations are discussed in Item 1A-Risk Factors.
EMPLOYEES
As of September 30, 2011, we employed approximately 4,400 persons. Approximately 520 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. 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 to 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 wireless communications semiconductor industry, which is subject to significant downturns.

demand for end-user products in both the consumer and enterprise markets. Continued uncertain economic conditions worldwide, together with other factors such as the continued 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 wireless communications semiconductor products has stabilized to some extent, continued uncertainty and economic weakness could result in another 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 wireless communications semiconductor industry may be prolonged, and any extended delay or failure of the wireless semiconductor 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 substantial quarterly and annual fluctuations and market downturns.
Our revenues, earnings and other operating results have fluctuated significantly on a quarterly and annual basis in prior fiscal years and our revenues, earnings and other operating results may fluctuate in the future. These fluctuations are due to 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 cellular handsets) 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 factors, including:

• | the recent unprecedented 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,

10

Table of Contents

• | 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 or buy/sell recommendations by analysts,

• | domestic and international political conditions, and

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

Public stock markets have recently experienced extreme 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, possible substantially over a short period of time.
The wireless communications 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 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 Avago Technologies, 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 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,

• | compliance with industry standards,

• | strategic relationships with customers,

• | access to and protection of intellectual property, and

• | maintaining access to 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,

11

Table of Contents

• | brand recognition,

• | high levels of customer satisfaction,

• | 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 wireless communications semiconductor industry generally and, in particular, 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 capacity sufficient 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,

• | 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, among other factors, on the viability and flexibility of our own internal information technology systems.
We will be required to continually evaluate expenditures for planned product development and to choose among alternative technologies based on our 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.
12

Table of Contents
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 our products to 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 adverse affect on our business.
Additionally, our operations may be affected by lengthy or recurring disruptions of operations at any of our production facilities or those of our subcontractors. 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 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. 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, which could result in higher costs and/or a loss of customers.
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 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, 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 perturbations in the manufacturing process can cause substantial manufacturing yield loss, and in some cases,
13

Table of Contents
cause production to be suspended. 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 will also face pressures arising from the compression of product life cycles, which will 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 test 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 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. If we choose to use a new foundry, it will typically take an extended period of time to complete our qualification process before we can begin shipping products from the new foundry. The 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 earthquake zones. 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.
Although we own and operate a test and assembly 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 continuing to develop relationships with additional third-party subcontractors to assemble and test our products. However, even if we use these new subcontractors, we will continue to be subject to all of the risks described above.
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 the components used in our manufacturing processes at a competitive cost. Although we maintain relationships with suppliers located around the world with the objective of ensuring that we have adequate sources for the supply of raw materials and components for our manufacturing needs, increases in demand from the semiconductor industry for such raw materials and components, as well as increased demand for commodities in general, can result in tighter supplies and higher costs. Our suppliers may not be able to meet our delivery schedules, we may lose a significant or sole supplier, a supplier may not be able to meet performance and quality specifications and we may not be able to purchase such supplies or material at a competitive cost. If a supplier were unable to meet our delivery schedules or if we lost a supplier or a supplier were unable to meet performance or quality specifications, our ability to satisfy customer obligations would be materially and adversely affected. In addition, we review our relationships with suppliers of raw materials and components for our manufacturing needs on an ongoing basis. In connection with our ongoing review, we may modify or terminate our relationship with one or more suppliers. We may also enter into sole supplier arrangements to meet certain of our raw material or component needs. While we do not typically rely on a single source of supply for our raw materials, we are currently dependent on a limited number of sole-source suppliers. If we were to lose these sole sources of supply, for any reason, a material adverse effect on our business could result until an alternate source is obtained. To the extent we enter into additional sole supplier arrangements for any of our raw materials or components, the risks associated with our supply arrangements would be exacerbated.

Our reliance on a small number of customers for a large portion of our sales could have a material adverse effect on the results of our operations.
Significant portions of our sales are concentrated among a limited number of customers. If we lost one or more of these major customers, or if one or more major customers significantly decreased its orders for our products, our business could be materially and adversely affected. In fiscal year 2011 and fiscal year 2010, Foxconn, Nokia 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 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 typically made pursuant to individual purchase orders 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.
15

Table of Contents
The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark and other intellectual property rights to technologies that are important to our business and have demanded and may in the future demand that we license their technology or refrain from using it.
Any litigation to determine the validity of claims that our products infringe or may infringe intellectual property rights of another, including claims arising from our contractual indemnification of our customers, regardless of their merit or resolution, could be costly and divert the efforts and attention of our management and technical personnel. Regardless of the merits of any specific claim, we may not prevail in litigation because of the complex technical issues and inherent uncertainties in intellectual property litigation. If litigation were to result in an adverse ruling, we could be required to:

• | pay substantial damages,

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

• | discontinue the use of infringing technology,

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

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

Our operating results or financial condition may be materially adversely affected if we, or one of our customers, were required to take any one or more of the foregoing actions.
In addition, if another supplier to one of our customers, or a customer of ours itself, were found to be infringing upon the intellectual property rights of a third party, the supplier or customer could be ordered to cease the manufacture, import, use, sale or offer for sale of its infringing product(s) or process(es), either of which could result, indirectly, in a decrease in demand from our customers for our products. If such a decrease in demand for our products were to occur, it could have an adverse impact on our operating results.
Many of our products currently incorporate technology licensed or acquired from third parties and we expect our products in the future to also require technology from third parties. If the licenses to such technology that we currently hold become unavailable or the terms on which they are available become commercially unreasonable, or if we are unable to acquire or license necessary technology for our products in the future, our business could be adversely affected.
We sell products in markets that are characterized by rapid technological changes, evolving industry standards, frequent new product introductions, short product life cycles and increasing levels of integration. Our ability to keep pace with this market depends on our ability to obtain technology from third parties on commercially reasonable terms to allow our products to remain competitive. If licenses to such technology are not available on commercially reasonable terms and conditions or at all, and we cannot otherwise acquire or integrate such technology, our products or our customers’ products could become unmarketable or obsolete, and we could lose market share. In such instances, we could also incur substantial unanticipated costs or scheduling delays to develop substitute technology to deliver competitive products.
If we are not successful in protecting our intellectual property rights, our ability to compete successfully may be materially and adversely affected.
We rely on patent, copyright, trademark, trade secret and other intellectual property laws, as well as nondisclosure and confidentiality agreements and other methods, to protect our proprietary technologies, information, data, devices, algorithms, processes and other intellectual property. In addition, we often incorporate the intellectual property of our customers, suppliers or other third parties into our designs, and we have obligations with respect to the non-use and non-disclosure of such third-party intellectual property. In the future, it may be necessary to engage in litigation or like activities to enforce our intellectual property rights, to protect our trade secrets or to determine the validity and scope of proprietary rights of others, including our customers. This could require us to expend significant resources and to divert the efforts and attention of our management and technical personnel from our business operations. Regardless of our actions:

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

16

Table of Contents

• | 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,

• | 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,

• | 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,

• | our future results could be adversely affected by changes in the effective tax rate as a result of our overall profitability and mix of earnings in countries with differing statutory tax rates and the results of audits and examinations of previously filed tax returns,

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

17

Table of Contents

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

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 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 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 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 semiconductor 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 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 electronics industry has been subject to increasing environmental regulations. 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.
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
18

Table of Contents
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 our solutions and those of our licensees and customers in the United States as well as foreign countries.
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. 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 solutions.
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, one-time write-offs,

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

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

• | 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. When 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,

ITEM 3. LEGAL PROCEEDINGS.
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, 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 our business and have demanded and may in the future demand that we 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 we are also involved in legal proceedings in the ordinary course of business.
On May 26, 2011, the Company announced it had entered into an agreement and plan of merger (the “Merger Agreement”) with PowerCo Acquisition Corp., a wholly owned subsidiary of the Company (“Merger Sub”) and Advanced Analogic Technologies Incorporated (“AATI”) pursuant to which the Merger Sub will, subject to the satisfaction or waiver of the conditions in the Merger Agreement, merge with and into AATI, and AATI will survive the merger and become a wholly owned subsidiary of the Company (the “Merger”). Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, each outstanding share of AATI common stock (except for shares held directly or indirectly by the Company, Merger Sub, AATI or any wholly owned subsidiary of AATI, and except for shares of AATI common stock held by stockholders exercising dissenter’s rights) will automatically be converted into the right to receive an aggregate of $6.13 per share.
Skyworks and AATI are parties to an arbitration proceeding pending before the Hon. Leo Strine in the Delaware Court of Chancery, in which Skyworks is seeking to be released from its obligations to proceed with the transactions contemplated by the Merger Agreement and AATI is seeking to require Skyworks to consummate the transactions contemplated by the Merger Agreement. Skyworks' petition, filed on September 26, 2011 and thereafter amended with leave of Chancellor Strine (acting as arbitrator), asserts claims against AATI for breach of Sections 5.1, 5.1(k), 5.1(n), 6.2 and 6.4 of the Merger Agreement and claims based on misrepresentations by AATI to Skyworks dating to before the signing of the Merger Agreement, and seeks an order (a) declaring that Skyworks is relieved of its obligations under the Merger Agreement, (b) declaring that Skyworks is entitled to terminate the Merger Agreement, and (c) in the alternative, awarding damages in an amount to be proven at final hearing. AATI's petition, filed by AATI on September 23, 2011, asserts claims against Skyworks for breach of the Merger Agreement and seeks (x) a declaratory judgment from the Court (i) that AATI has not breached the merger agreement, (ii) that no “material adverse effect” has occurred with respect to AATI, and (iii) that Skyworks has breached its obligations under the Merger Agreement, (y) an order of specific performance of the Merger Agreement compelling Skyworks to close the merger, and (z) in the alternative, damages in an amount to be proven at final hearing. The petitions have been consolidated for all purposes of the arbitration proceedings, and the hearing is currently scheduled to take place in the last week of November and the first week of December 2011. Skyworks is unable to predict the outcome of the proceedings.
Under Delaware law, applicable stipulations and orders, and the applicable provisions of the Merger Agreement, the arbitration proceedings are confidential, subject to the parties' disclosure obligations under federal securities law and other applicable laws. Subject to such obligations, Skyworks does not intend to comment or provide information regarding the arbitration until an order on the merits or other material order is issued in the arbitration or the arbitration process is otherwise concluded.
On June 6, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No.
21

Table of Contents
111CV202403) (the “Bushansky action”) naming AATI, the members of AATI’s board of directors, the Company and Merger Sub as defendants. The complaint alleges, among other things, (1) that the members of AATI’s board of directors breached their fiduciary duties by (a) failing to take steps to maximize the value of the merger consideration to AATI’s stockholders, (b) taking steps to avoid competitive bidding, and (c) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, and (2) that AATI, the members of AATI’s board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The complaint seeks to enjoin consummation of the merger or, if the merger is completed, to recover damages caused by the alleged breaches of fiduciary duties. The complaint also seeks recovery of attorney’s fees and costs of the lawsuit.
On June 7, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202501) (the “Venette action”) naming AATI, the members of AATI’s board of directors, the Company and Merger Sub as defendants. Plaintiffs filed an amended complaint on July 14, 2011 (the “Amended Complaint”). The Amended Complaint alleges, among other things, (1) that the members of AATI’s board of directors breached their fiduciary duties by (a) agreeing to the merger for inadequate consideration on unfair terms, (b) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, (c) selling the company in response to alleged pressure from Dialectic Capital Partners, LP (“Dialectic”), (d) taking steps to avoid competitive bidding (including the entry by certain AATI officers and directors into agreements with the Company relating to voting commitments and inclusion in the merger agreement of non-solicitation provisions and a termination fee), and (e) by causing the issuance of a materially misleading Form S-4 Registration Statement which, inter alia, purportedly fails to disclose material facts surrounding (i) Dialectic’s impact on the proposed merger process, (ii) the AATI board of directors’ evaluation of the Company and its offer for AATI, and (iii) supporting figures and analysis regarding the fairness opinion that the AATI Board obtained from its financial advisor, Needham & Company, LLC, in connection with the transaction and (2) that AATI, the members of AATI’s board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The Amended Complaint seeks to enjoin consummation of the merger, and to have the court direct the defendants to implement procedures and processes to maximize shareholder value. The Amended Complaint also seeks recovery of attorney’s fees and costs of the lawsuit.
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 the Amended Complaint as the operative complaint in the litigation. The Company believes that the claims in the consolidated action are without merit and intends to defend against such claims vigorously.
We believe that there are no other pending litigation involving the Company that will have, individually or in the aggregate, a material adverse effect on our business.

GENERAL
During fiscal year 2011, certain key factors contributed to our overall results of operations and cash flows from operations. More specifically:

• | Smart phones are entering the stage of mass market adoption and becoming a more integral part of consumers' daily lives. These devices increasingly incorporate mobile internet connectivity, social networking, portable gaming, digital cameras, high definition camcorders and mobile payment systems in addition to the functionality of traditional mobile phones. This trend creates a higher dollar content per handset which results in an expanded market opportunity for Skyworks' devices. Our growing addressable market, coupled with increasing market share and strategic acquisitions made during the year are the primary drivers of the approximately 32.4% revenue growth to $1.4 billion in fiscal year 2011.

• | Gross profit increased by $163.5 million or 110 basis points to 43.7% of net revenue for the fiscal year ended September 30, 2011 as compared to fiscal year 2010. The increase in gross profit in aggregate dollars and as a percentage of net revenue is primarily the result of enhanced product mix, lower manufacturing costs as a result of higher factory utilization, and the aforementioned increase in net revenue.

• | Operating income increased by $95.6 million or 47.9% over the prior year to 20.8% of revenue for fiscal year 2011. The increase is primarily due to the aforementioned increases in net revenue and gross margin along with a higher degree of operating leverage as the Company maintained relatively constant operating expenditures.

• | We generated $365.8 million in cash from operations during fiscal year 2011 resulting in an ending cash, cash equivalents and restricted cash balance of $410.8 million at September 30, 2011 even after factoring in the use of $249.3 million of cash for acquisitions, net of cash received, $100.7 million of cash on capital expenditures and $70.0 million of cash for shares repurchased.

• | In June 2011, we acquired SiGe for $278.9 million in total consideration. SiGe is a leading global supplier of RF front-end solutions that facilitate wireless multimedia across a wide range of applications. The acquisition of SiGe complements the Company’s leadership in wide area front-end solutions by adding SiGe's innovative short range, silicon-based products. As a result, the Company now offers customers a more comprehensive wireless networking product portfolio, supporting all key operating frequencies with greater architectural flexibility to address a variety of high growth applications. SiGe contributed approximately 2.8% to our 32.4% revenue growth in fiscal year 2011.

NET REVENUE

| Fiscal Years Ended
| September 30, 2011 | Change | October 1, 2010 | Change | October 2, 2009
(dollars in thousands) |  |  |  |  |
Net revenue | $ | 1,418,922 |  | 32.4 | % | $ | 1,071,849 |  | 33.6 | % | $ | 802,577 |

We market and sell our products directly to Original Equipment Manufacturers (“OEMs”) of communication electronic products, third-party Original Design Manufacturers (“ODMs”), 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 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 the fiscal year.
Overall revenue in fiscal year 2010 increased by $269.3 million, or 33.6%, from fiscal year 2009. This revenue increase was principally driven by market share gains and higher overall demand for our products used in mobile internet, wireless infrastructure, energy management and diversified analog devices.
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 30, 2011 | Change | October 1, 2010 | Change | October 2, 2009
(dollars in thousands) |  |  |  |  |
Gross profit | $ | 620,304 |  | 35.8 | % | $ | 456,833 |  | 43.6 | % | $ | 318,220 |
% of net revenue | 43.7 | % |  | 42.6 | % |  | 39.6 | %

Gross profit represents net revenue less cost of goods sold. Cost of goods sold consists primarily of purchased materials, labor and overhead (including depreciation and share-based compensation expense) associated with product manufacturing.
We increased our gross profit by $163.5 million for the fiscal year ending 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 aforementioned increase in net revenue. During fiscal 2011 we continued to benefit from higher contribution margins associated with the licensing and/ or sale of intellectual property.
We increased our gross profit by $138.6 million for the fiscal year ended October 1, 2010 as compared to the prior fiscal year, resulting in a 300 basis point expansion in gross profit margin to 42.6%. This was principally the result of continued factory process and productivity enhancements, product end-to-end yield improvements, year-over-year material cost reductions, targeted capital expenditure investments and the aforementioned increase in net revenue. During fiscal 2010 we continued to benefit from higher contribution margins associated with the licensing and/ or sale of intellectual property.

% of net revenue | 11.9 | % |  | 12.5 | % |  | 15.4 | %

Research and development expenses consist primarily of direct personnel costs, costs for pre-production evaluation and testing of new devices, masks and engineering prototypes, share-based compensation expense and design and test tool costs.
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 aforementioned increase in net revenue.
The 8.2% increase in research and development expenses in fiscal year 2010 when compared to fiscal year 2009 is principally attributable to higher head count and related compensation costs. In addition, the Company had increased design activity resulting in higher mask, prototype and materials costs in support of increased product development for our target markets. Research and development expenses decreased as a percentage of net revenue for fiscal year 2010 as a result of the aforementioned increase in net revenue.

Selling, general and administrative expenses include legal, accounting, treasury, human resources, information systems, customer service, bad debt expense, sales commissions, share-based compensation expense, advertising, marketing and other costs.
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 aforementioned increase in fiscal year 2011 revenue.
The increase in selling, general and administrative expenses for fiscal year 2010 as compared to fiscal year 2009 is principally due to share-based compensation which increased primarily as a result of our increased stock price in fiscal year 2010 as compared to 2009. Selling, general and administrative expenses as a percentage of net revenue decreased for fiscal year 2010, as compared to fiscal year 2009, due to the aforementioned increase in fiscal year 2010 revenue.

Provision (benefit) for income taxes | $ | 67,301 |  | 16.5 | % | $ | 57,780 |  | 329.0 | % | $ | (25,227 | )
% of net revenue | 4.7 | % |  | 5.4 | % |  | (3.1 | )%

Income tax expense was $67.3 million for fiscal 2011, compared to $57.8 million for fiscal year 2010. The annual effective tax rate for fiscal year 2011 was 22.9% as compared to a tax rate of 29.6% for fiscal year 2010.
As a result of the United States Government 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.
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 less than the United States federal rate, benefits of 6.0% related to the research and development tax credits and benefits of 2.1% related to a domestic production activities deduction partially offset by income tax expense of 3.2% related to a change in our tax reserves.
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.
Income tax expense was $57.8 million for fiscal 2010, compared to benefit of $25.2 million for fiscal year 2009. The annual effective tax rate for fiscal year 2010 was 29.6% as compared to a tax benefit of 36.2% for fiscal 2009.
The annual effective tax rate for fiscal 2010 of 29.6% was less than the United States federal statutory rate of 35% primarily due to benefits of 4.6% related to foreign earnings taxed at a less than the United States federal rate, benefits of 3.0% related to the research

and development tax credits, benefits of 1.8% related to an international restructuring to a lower tax jurisdiction and benefits of 1.2% related to a domestic production activities deduction partially offset by income tax expense of 2.3% and 1.5% related to changes in our tax reserves and valuation allowance, respectively.
During fiscal year 2010, we restructured our 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, we are no longer required to assess United States income tax on the earnings of our Mexican business.

_________________________

(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 2011 we generated $365.8 million in cash flow from operations, an increase of $142.8 million when compared to $223.0 million generated in fiscal year 2010. The increase was primarily due to the increase in net income of $89.3 million for fiscal year 2011, and the increase in non-cash expenses such as depreciation of $59.8 million, share based compensation of $58.3 million, amortization of intangibles of $16.7 million, offset by the change in net working capital.
Cash Flow from Investing Activities:
Cash used in investing activities consists of cash paid for acquisitions, net of cash acquired, and capital expenditures. We had net cash outflows of $349.9 million in fiscal year 2011, compared to $95.3 million in fiscal year 2010. The increase resulted from cash paid for acquisitions of $249.3 million (net of cash received), primarily for SiGe and $100.7 million in capital expenditures during the year.
Cash Flow from Financing Activities:
Cash flows from financing activities consist primarily of cash transactions related to debt and equity. During fiscal year 2011, we had net cash outflows of $59.0 million, compared to $38.6 million in fiscal year 2010. During fiscal year 2011 we had the following significant uses of cash:

• | $70.0 million related to our repurchase of approximately 2.8 million shares of our common stock pursuant to the share repurchase program approved by our Board of Directors on August 3, 2010;

• | $50.0 million related to the repayment and termination of the Credit Facility; and

• | $20.1 million related to payroll tax withholdings on the vesting of employee performance and restricted stock awards.

These uses of cash were partially offset by the net proceeds from employee stock option exercises of $63.2 million, tax benefit from stock option exercises of $12.5 million and a decrease in restricted cash of $5.4 million during fiscal 2011.
Liquidity:
Cash and cash equivalent balances (excluding restricted cash) decreased $43.2 million to $410.1 million at September 30, 2011 from $453.3 million at October 1, 2010. This decrease was primarily due to the $249.3 million in cash paid for acquisitions, $100.7 million in capital expenditures and $70.0 million for share repurchases during the year offset by our cash provided by operations of $365.8 million. Our net cash position, after deducting our debt, increased by $5.5 million to $384.0 million at September 30, 2011 from $378.5 million at October 1, 2010. On May 26, 2011, we announced that we had entered into a definitive agreement under which we intend to acquire all the outstanding shares of AATI for $6.13 per share in a combination of cash and stock. In the event that the Company's stock price is below $21.00 per share on the date of acquisition and elects an all cash transaction, the Company expects to pay approximately $190.0 million and $200.0 million net of approximately $80.0 million to $90.0 million of cash expected to be received in the transaction. Based on our historical results of operations, we expect our existing sources of liquidity, together with
29

Table of Contents
cash expected to be generated from operations, will be sufficient to fund our research and development, capital expenditures, debt obligations including the cash premium, contingent consideration for our completed acquisitions, pending and future acquisitions, working capital and other cash requirements for at least the next 12 months. However, we cannot be certain that the capital required to fund these expenses will be available in the future. In addition, any strategic investments and acquisitions that we may make may require additional capital resources. If we are unable to obtain sufficient 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. At September 30, 2011, we also held a $3.2 million par value auction rate security with a fair value of $2.3 million on which we continue to receive the scheduled interest payments. We continue to monitor the liquidity and accounting classification of this security. If in a future period we determine that the impairment is other than temporary, we will impair the security to its fair value and charge the loss to earnings.
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).
CONTRACTUAL CASH FLOWS
Following is a summary of our contractual payment obligations related to our consolidated debt, contingent consideration, operating leases, other commitments and long-term liabilities at September 30, 2011 (see Notes 9 and 13 of Item 8 of this Annual Report on Form 10-K), (in thousands):

(1) | Cash premiums related to the "if converted" value of the 2007 Convertible Notes that exceed aggregate principal balance using the closing stock price of $17.96 on September 30, 2011. The actual amount of the cash premium will be calculated based on the 20 day average stock price prior to maturity. A $1.00 change in our stock price would change the "if converted" value of the cash premium of the total aggregate principle amount of the remaining convertible notes by approximately $2.8 million. See Note 9 of Item 8 of this Annual Report on Form 10-K for further detail.

(2) | Other commitments consist of contractual license and royalty payments, and other purchase obligations.

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

(4) | Other long-term liabilities includes 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 commitment.

(5) | Amounts do not include potential cash payments for the pending acquisition of AATI. See Note 3 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

Table of Contents
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, allowance for doubtful accounts, inventory valuation, business combinations, valuation of long-lived assets, share-based compensation, income taxes, goodwill and intangibles, and loss contingencies.
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.

Description |  | Judgments and Uncertainties |  | Effect if Actual Results Differ From Assumptions
Revenue Recognition |  |  |  |
We recognize revenue in accordance with ASC 605 Revenue Recognition net of estimated reserves. We maintain revenue reserves for product returns and allowances for price protection / 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. |  | We have not made any material changes in our accounting methodology used to record revenue reserves during the last three fiscal years. We do not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions that would have a material impact to earnings.
Allowance for Doubtful Accounts |  |  |  |
We record an allowance for doubtful accounts for amounts that we estimate will arise from customers’ inability to make required payments against amounts owed on credit sales. The reserve is based on the analysis of credit risk and aged receivable balances. |  | Our allowance for doubtful accounts methodology contains uncertainties because it requires management to apply judgment to evaluate credit risk and collectability of aged accounts receivables based on historical experience and forward looking assumptions. |  | There have been no material changes in our accounting methodology used to calculate the allowance for doubtful accounts during the year. The process by which we evaluate customer creditworthiness was modified in fiscal year 2010 for purposes of establishing our allowance. This did not have a material effect on our balance. We do not believe there is a reasonable likelihood that there will be a material change in future estimates or assumptions that would have a material impact to earnings.
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, salability 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. |  | We have not made any material changes to our inventory reserve methodology during the last three fiscal years. We do not believe that significant changes will be made in future estimates or assumptions we use to calculate these reserves. However, if our estimates are inaccurate or changes in technology affect consumer demand we may be exposed to unforeseen gains or losses. A 10% difference in our inventory reserves as of September 30, 2011 would affect fiscal year 2011 earnings by approximately $1.1 million.

Description |  | Judgments and Uncertainties |  | Effect if Actual Results Differ From Assumptions
Business Combinations |  |  |  |
The Company has applied significant estimates and judgments in order to determine the fair value of the identified assets acquired, liabilities assumed, goodwill recognized and the contingent consideration recorded as part of business combinations. The value of the 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 made in performing the valuation 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. |  | We do not believe that there is a reasonable likelihood that there will be material changes to our estimates or assumptions. However, if actual results are not consistent with our evaluation or assumptions, additional and/or new information arises in the future that affects the fair value estimates could result in adjustments that may have a material impact to the purchase accounting or results of operations.
Valuation of Long-Lived Assets |  |  |  |
Long-lived assets other than goodwill and indefinite-lived intangible assets, which are separately tested for impairment, are evaluated for impairment whenever events or circumstances arise that may indicate that the carrying value of the asset may not be recoverable. When evaluating long-lived assets for potential impairment, we first compare the carrying value of the assets to the asset’s estimated undiscounted future cash flows (excluding interest). If the estimated undiscounted future cash flows are less than the carrying value of the asset or asset group, we would recognize an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the asset or asset group. |  | Our impairment loss calculations contain uncertainties because they require management to make assumptions and to apply judgment to estimate asset fair values, including estimating future cash flows, useful lives and selecting an appropriate discount rate that reflects the risk inherent in future cash flows. |  | We have not made any material changes in the accounting methodology we use to assess impairment loss during the past three fiscal years. We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions we use to calculate long-lived asset impairment losses. However, if actual results are not consistent with our estimates and assumptions used in estimating future cash flows and asset fair values, we may incur material losses.
Share-Based Compensation |  |  |  |
We have a share-based compensation plan which includes non-qualified stock options, share awards, and an employee stock purchase plan. 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 stock 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. |  | We have not made any material changes in the accounting methodology we used to calculate share-based compensation during the past three fiscal years. We do not believe that there is a reasonable likelihood there will be a material change in future estimates or assumptions used to determine share-based compensation expense. However, if actual results are not consistent with our estimates or assumptions, we may be exposed to a material change in share-based compensation expense. A 10% difference in our share-based compensation expense for the year ended September 30, 2011 would affect fiscal year 2011 earnings by approximately $5.8 million.

Description |  | Judgments and Uncertainties |  | Effect if Actual Results Differ From Assumptions
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 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. |  | We have not made any material changes in the accounting methodology we use to assess loss contingencies in the past three years. We do not believe there is a reasonable likelihood that there will be material changes to our estimates or assumptions. However, if actual results are not consistent with our evaluation or assumptions, there could be a material impact to earnings.
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, 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. |  | We have not made any material changes in the accounting methodology we used to measure our deferred tax assets and liabilities or reserves for additional income tax liabilities. If our estimate of income tax liabilities proves to be less than the ultimate assessment, or events cause us to change our estimate of probable additional income tax liability, a further charge to expense would be required. The Company expects to continue to be profitable and therefore has determined that a valuation allowance is not required against our deferred tax assets, except for certain state and foreign tax credits. If certain events cause us to change our estimate of the realizability of our deferred tax assets and liabilities, a further charge to expense would be required.

Goodwill and Intangible Assets |  |  |  |
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 intangibles may not be recoverable. Intangible assets with indefinite useful lives comprise an insignificant portion of the total book value of our goodwill and intangible assets. Pursuant to the guidance provide under ASC 280-Segment Reporting, we have determined that we have only one reporting unit for the purposes of allocating and testing goodwill. The impairment evaluation 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, 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 analysis contains uncertainties because it requires management to make assumptions and to apply judgment to estimate control premiums, discount rate, future cash flows and the profitability of future business strategies. |  | We have not made any material changes in the accounting methodology we use to assess impairment loss during the past three fiscal years. The carrying value of goodwill and indefinite-lived intangible assets at September 30, 2011 were $663.0 million and $3.9 million, respectively. Based on the results of our impairment test, we had a significant excess fair value over the carrying value. We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions we use to calculate goodwill and intangible asset impairment losses. However, if actual results are not consistent with our estimates and assumptions used in estimating future cash flows and asset fair values, we may be exposed to losses that could be material.

OTHER MATTERS
Inflation did not have a material impact upon our results of operations during the three-year period ended September 30, 2011.
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, which as of September 30, 2011 consisted of the following (in thousands):

Cash and cash equivalents (time deposits and money market funds) | $ | 410,087 |
Restricted cash (time deposits and certificates of deposit) | 712 |
Available for sale securities (auction rate securities) | 2,288 |
| $ | 413,087 |

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. Available for sale securities carry a longer maturity period (contractual maturities exceed ten years).
Our short-term debt at September 30, 2011 consists of $26.7 million aggregate principal amount of our remaining 2007 Convertible Notes which are due in March 2012. The 2007 Convertible Notes contain cash settlement provisions should the share price of the Company’s common stock exceed $9.52. It has been the Company’s historical practice to cash settle the principal and interest components of convertible debt instruments, and it is our intention to continue to do so in the future. As of September 30, 2011, based on the closing stock price on September 30, 2011 of $17.96, the actual "if converted" value of the remaining Convertible Notes was $50.3 million which exceeds the related principal amount by approximately $23.6 million. The actual amount of the cash premium will be calculated based on the 20 day average stock price prior to maturity. A $1.00 change in our stock price would change the "if converted" value of the cash premium of the total aggregate principle amount of the remaining convertible notes by approximately $2.8 million.
We do not believe that investment or interest rate risk is material to our business or results of operations.
Our cash and cash equivalents at September 30, 2011 consisted of $335.3 million held domestically, with the remaining balance of $75.5 million held by foreign subsidiaries. There may be adverse tax effects upon repatriation of these funds to the United States.
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 30, 2011, October 1, 2010, and October 2, 2009, the Company had foreign exchange gains/(losses) of $0.3 million, $(0.6) million, and $0.7 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 30, 2011 and October 1, 2010, and the related consolidated statements of operations, cash flows, and stockholders' equity and comprehensive income (loss) for each of the years in the three-year period ended September 30, 2011. In connection with our audit of the consolidated financial statements, we also have audited the financial statement schedule listed in Item 15 of the 2011 Form 10-K. We also have audited Skyworks Solutions Inc.'s internal control over financial reporting as of September 30, 2011, 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 and financial statement schedule, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control over Financial Reporting. 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 consolidated financial position of Skyworks Solutions, Inc. and subsidiaries as of September 30, 2011 and October 1, 2010, and the results of their operations and their cash flows for each of the years in the three-year period ended September 30, 2011, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements 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 30, 2011, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Skyworks Solutions, Inc. acquired SiGe Semiconductor, Inc. during 2011, and management excluded from its assessment of the effectiveness of Skyworks Solutions, Inc. internal control over financial reporting as of September 30, 2011, SiGe Semiconductor, Inc's internal control over financial reporting associated with total assets of 15.9% (of which 12.5% represented goodwill and intangible assets included within the scope of the assessment) and total revenues of 2.8% included in the consolidated financial statements of Skyworks Solutions, Inc. as of and for the year ended September 30, 2011. Our audit of internal control over financial reporting of Skyworks Solutions, Inc. also excluded an evaluation of the internal control over financial reporting of SiGe Semiconductor, 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 2011, 2010 and 2009 each consisted of 52 weeks and ended on September 30, 2011, October 1, 2010 and October 2, 2009, 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
Revenues from product sales are recognized upon shipment and transfer of title, in accordance with the shipping terms specified in the arrangement with the customer. Revenue from license fees and intellectual property is recognized when due and payable, and all other criteria of 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 us 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.

Table of Contents
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 maturities of 90 days or less.
RESTRICTED CASH
Restricted cash is primarily used to collateralize the Company’s open letters of credit.
INVESTMENTS
The Company’s investment is classified as available for sale and consists of an auction rate security (“ARS”).
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 debt and 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 and amortization. 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
43

Table of Contents
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 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 FASB 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 goodwill and intangible assets. The Company assesses the need to test its goodwill for impairment on a regular basis. Pursuant to the guidance provided under 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 only 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 during such period and other marketplace activity and related control premiums. 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 the book value of its goodwill. If the book value of the Company’s goodwill exceeds the implied fair value of its goodwill, an impairment loss is recognized equal to that excess. In step two of the Company’s annual impairment analysis, 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 have become impaired and result in additional interim impairment testing.
In fiscal year 2011, 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 none of the Company’s goodwill was impaired based on step one of the test; accordingly step two of the test was not performed.
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 employee stock options, employee stock purchases related to the Company’s 2002 Employee Stock Purchase Plan, restricted stock 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 stock-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 30, 2011 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 30, 2011 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.
44

Table of Contents
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, 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. For more complex awards with market-based performance conditions, the Company employs a Monte Carlo simulation method which calculates many potential outcomes for an award 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.
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. With the implementation effective September 29, 2007, 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.
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.

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 costs, including legal costs are recorded to expense as 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 2, 2009 | $ | (468 | ) |  | $ | (912 | ) |  | $ | (1,380 | )
Pension adjustment | 83 |  |  | — |  |  | 83 |
Balance as of October 1, 2010 | $ | (385 | ) |  | $ | (912 | ) |  | $ | (1,297 | )
Pension adjustment | (34 | ) |  | — |  |  | (34 | )
Balance as of September 30, 2011 | $ | (419 | ) |  | $ | (912 | ) |  | $ | (1,331 | )

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
In December 2010, the FASB issued Accounting Standards Update (“ASU”) -2010-29 Business Combinations which addresses the diversity in practice about the interpretations of the pro forma revenue and earnings disclosure requirements for business combinations. This update requires public entities that present comparative financial statements to disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the year had occurred as of the beginning of the comparable prior annual reporting period only. The amendment also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments that are included in the pro forma revenue and earnings. This guidance is effective on a prospective basis for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning after December 15, 2010. The Company elected to early adopt this standard and it did not have a material impact on its financial position or results of operations.
In December 2010 and September 2011, the FASB issued ASU 2010-28 and ASU 2011-08 Intangibles - Goodwill and Other, respectively, which both modify the annual goodwill impairment testing procedures. ASU 2010-28 focuses on the carrying amount of goodwill for purposes of performing step one of the goodwill test and ASU 2011-08 focuses on allowing entities the ability to first assess the qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Both of these updates are effective for annual and interim reporting periods beginning after December 15, 2011 and early adoption is permitted. ASU 2010-28 requires retrospective application. The Company elected not to early adopt either of these updates and does not expect the adoption will have a material impact on its goodwill impairment calculation, financial position or results of operations.
In May 2011, the FASB issued ASU-2011-04 Fair Value Measurement that modifies the fair value measurements and disclosure requirements in U.S. GAAP and IFRS. This newly issued accounting standard clarifies the application of certain existing fair value measurement guidance and expands the disclosures for fair value measurements that are estimated using significant unobservable inputs. This guidance is effective on a prospective basis for annual and interim reporting periods beginning after December 15, 2011. The Company does not expect that adoption of this standard will have a material impact on its financial position or results of operations.
In June 2011, the FASB issued ASU 2011-05 Statement of Comprehensive Income which (1) eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity; (2) requires the consecutive
46

Table of Contents
presentation of the statement of net income and other comprehensive income; and (3) requires an entity to present reclassification adjustments on the face of the financial statements from other comprehensive income to net income. The FASB is currently considering deferral of the third requirement under this ASU but has not made a decision regarding the outcome as of the date of this annual report. This amendment does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income nor does this amendment affect how earnings per share is calculated or presented. This guidance is required to be applied retrospectively and is effective for fiscal years and interim periods beginning after December 15, 2011. The Company does not expect that adoption of this standard will have a material impact on its financial position or results of operations.
3. BUSINESS COMBINATIONS
On April 27, 2011, the Company acquired 100% ownership of a private company engaged in the design and manufacturing of optical components for $28.8 million (net of cash acquired and including an estimated fair value of $2.0 million of contingent consideration which is not materially different than the maximum earn-out level). The acquisition has an immaterial impact to the Company’s results of operations (i.e., contributed less than one percent of net revenue for the fiscal year ended September 30, 2011) and accordingly, the disclosures required per the business combination topic of the Accounting Standards Codification have been excluded from this annual report on Form 10-K. Although the purchase price allocation is preliminary, the Company has recognized assets primarily related to intellectual property, land, building and goodwill.
On June 10, 2011, the Company completed the acquisition of SiGe Semiconductor, Inc. (“SiGe”), a semiconductor provider. The Company acquired a 100% ownership interest in SiGe for an aggregate purchase price of $278.9 million in cash, including contingent consideration, payable in cash, approximately one year from the acquisition date, with an estimated fair value of $57.4 million. The possible outcome of the contingent consideration ranges from zero to $65.0 million and is based on the achievement of a specified revenue target over the twelve month period following the date of the acquisition. SiGe is a leading global supplier of RF front-end solutions that facilitate wireless multimedia across a wide range of applications. The acquisition of SiGe complements the Company’s leadership in wide area front-end solutions by adding SiGe's innovative short range, silicon-based products. As a result, the Company now offers customers a more comprehensive wireless networking product portfolio, supporting all key operating frequencies with greater architectural flexibility to address a variety of high growth applications.
The allocation of purchase price consideration in the Company’s acquisition of SiGe to the assets and liabilities was not finalized at the time of filing this annual report on Form 10-K due to the proximity of the acquisition date of June 10, 2011 to the end of the fiscal year, September 30, 2011. The Company has, however, completed a preliminary purchase price allocation and accordingly, the Company has reflected a preliminary allocation of the purchase price in the accompanying financial statements. The preliminary allocation of the purchase price was based upon estimates and assumptions which are subject to change within the measurement period (up to one year from the acquisition date). 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 SiGe acquisition and are reflected in the accompanying financial statements as follows (in thousands):

| June 10, 2011
Estimated fair value of assets acquired |
Cash and cash equivalents | $ | 6,689 |
Receivables, net | 14,176 |
Inventory | 17,457 |
Other current assets | 2,942 |
Property, plant and equipment | 3,551 |
Deferred tax assets, net | 20,648 |
Intangible assets | 74,270 |
Goodwill | 162,387 |
Total assets acquired | 302,120 |
Estimated fair value of liabilities assumed |
Total liabilities assumed | (23,188 | )
Net assets acquired | $ | 278,932 |

The allocation of purchase price is considered preliminary until the end of the measurement period. However, during the fiscal year ended September 30, 2011, the Company recorded adjustments to its purchase accounting for SiGe as reported during the third fiscal quarter. The Company reduced the total consideration paid as a result of a net working capital adjustment and recorded additional
47

Table of Contents
deferred tax assets. Both of these adjustments resulted in a reduction of goodwill as of September 30, 2011.
The preliminary amount of purchase price allocated to goodwill of $162.4 million relates to revenue and cost synergies the Company expects to capitalize on as a result of the business combination. Substantially all of the goodwill recognized as a result of the SiGe acquisition is not expected to be deductible for tax purposes.
The preliminary amount of the purchase price allocated to identified intangible assets recognized in the acquisition of SiGe and the respective estimated useful lives as of June 10, 2011 were as follows (in thousands):

| Fair Value | Weighted Average Amortization Period (in Years)
Intellectual property | $ | 36,660 |  | 5
Customer relationships | 26,200 |  | 5
In-process research and development | 4,510 |  | TBD
Backlog | 3,900 |  | 0.3
Trademark | 3,000 |  | 5
Total identifiable intangible assets | $ | 74,270 |  |

Intellectual property primarily represents the fair value of the SiGe product technologies (including patents) acquired. Customer relationships represent the fair value of the underlying relationships and agreements with SiGe customers. In-process research and development represents the fair value of incomplete SiGe research and development projects that had not reached technological feasibility as of the acquisition date, June 10, 2011. 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 are completed. If a project is determined to be cancelled or does not meet technological feasibility, the value associated with that project will be written off in the period the determination is made. Backlog represents the fair value of SiGe unfilled orders as of the acquisition date, June 10, 2011. The trademark represents the brand and name recognition associated with the marketing of SiGe products and was determined to have a finite life. The Company used a combination of income approaches to assess the preliminary fair values of the intangible assets and as a result, considers the fair value of these acquired assets to be Level 3 assets due to the significant assumptions used in the valuation. See Note 5, Fair Value for the definition of Level 3 assets.
Net revenue and net income for acquisitions completed during the fiscal year ended September 30, 2011 have been included in the consolidated statements of operations from their respective acquisition dates. SiGe contributed approximately $39.7 million of net revenue to the consolidated results of operations for the fiscal year ended September 30, 2011. The impact of SiGe's ongoing operations on the Company’s net income was insignificant to the fiscal year ended September 30, 2011. The transaction related costs associated to the SiGe acquisition were considered immaterial and included within selling, general and administrative expense for the fiscal year ended September 30, 2011.
The unaudited pro forma financial results for the fiscal years ended September 30, 2011 and October 1, 2010 combine the unaudited historical results of Skyworks along with the unaudited historical results of SiGe for the fiscal years ended September 30, 2011 and October 1, 2010, respectively. The results include the effects of unaudited pro forma adjustments as if SiGe was acquired on October 3, 2009. There were no material nonrecurring pro forma adjustments in the calculation of revenue or earnings. The pro forma financial results presented below do not include any anticipated synergies or other expected benefits of the acquisition. These results are presented for informational purposes only and are not necessarily indicative of future operations (in thousands, except per share amounts):

| Fiscal Years Ended
| September 30, 2011 |  | October 1, 2010
Revenue | $ | 1,490,960 |  |  | $ | 1,174,057 |
Net income | $ | 209,016 |  |  | $ | 129,258 |
Basic EPS | $ | 1.14 |  |  | $ | 0.74 |
Diluted EPS | $ | 1.10 |  |  | $ | 0.71 |

Pending acquisition
On May 26, 2011, the Company announced it had entered into an agreement and plan of merger (the “Merger Agreement”) with PowerCo Acquisition Corp., a wholly owned subsidiary of the Company (“Merger Sub”) and Advanced Analogic Technologies
48

Table of Contents
Incorporated (“AATI”) pursuant to which the Merger Sub will, subject to the satisfaction or waiver of the conditions in the Merger Agreement, merge with and into AATI, and AATI will survive the merger and become a wholly owned subsidiary of the Company (the “Merger”). Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, each outstanding share of AATI common stock (except for shares held directly or indirectly by the Company, Merger Sub, AATI or any wholly owned subsidiary of AATI, and except for shares of AATI common stock held by stockholders exercising dissenter’s rights) will automatically be converted into the right to receive an aggregate of $6.13 per share, payable in the form of 0.08725 of a share of the Company’s common stock (the “stock consideration”) and an adjustable cash amount in the initial calculated amount of $3.68 (the “cash consideration” and, together with the stock consideration, the “merger consideration”), without interest and less applicable withholding taxes. The amount of the stock consideration was based on the average last sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) over the 30-trading days prior to May 26, 2011. At that average price, the stock consideration had a nominal value of $2.45 and the nominal aggregate combined value of the cash consideration and the stock consideration was $6.13. The final cash consideration will depend on the closing value of the stock consideration, calculated on the basis of Skyworks’ average reported last sale price in regular Nasdaq trading during a five-trading-day measurement period preceding the closing of the merger. If the closing value of the stock consideration is less than $2.45, the cash consideration will increase by the amount of the shortfall. If the closing value of the stock consideration is more than $2.45, the cash consideration will decrease by the amount of the excess. If the closing value of the stock consideration is exactly $2.45, the cash consideration will remain unchanged at $3.68. In each case, the merger consideration will maintain a constant nominal aggregate combined value of $6.13 per share of AATI common stock. If the Company’s average last reported sale price during the pre-closing measurement period is less than $21.00 per share, the Company has the right to pay the entire $6.13 in cash, and in that event, AATI stockholders would not receive any shares of the Company’s Common Stock in the merger for their outstanding shares of AATI common stock, and would instead receive $6.13 entirely in cash. In the event that the Company's stock price is below $21.00 per share on the date of acquisition and elects an all cash transaction, the Company expects to pay approximately $190.0 million to $200.0 million in cash net of approximately $80.0 million to $90.0 million of cash expected to be acquired in the transaction. For additional information regarding the pending acquisition, see Note 14, Contingencies.
4. MARKETABLE SECURITIES
The Company accounts for its investment in marketable securities in accordance with ASC 320-Investments-Debt and Equity Securities ("ASC 320"), and classifies them as “available for sale”. At September 30, 2011, these securities consisted of $3.2 million par value in ARS, with a carrying value of $2.3 million. The difference between the par value and the carrying value is categorized as a temporary loss in other comprehensive income. The Company receives the scheduled interest payments in accordance with the terms of the ARS. The Company closely monitors and evaluates the appropriate accounting treatment in each reporting period for the ARS.
5. FAIR VALUE
In accordance with ASC 820 - Fair Value Measurements and Disclosure (“ASC 820”), the Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
Level 1 - Valuation is based upon quoted market price for identical instruments traded in active markets.
Level 2 - Valuation is based upon quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques.
The Company has cash equivalents classified as Level 1 and has no Level 2 securities. The Company's ARS, discussed in Note 4, Marketable Securities, are classified as Level 3 assets.

The increases in goodwill and intangible assets during the fiscal year ended September 30, 2011 resulted from the acquisitions, primarily SiGe, during the fiscal year ended September 30, 2011 as discussed in Note 3, Business Combinations.
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 that the carrying value of goodwill or non-amortizing trademarks may be impaired. The results of the annual impairment tests indicated that none of the goodwill or trademarks had been impaired during the year and as a result, step two was not performed. There were no other indicators of impairment noted during the fiscal year ended September 30, 2011.
Annual amortization expense for the next five years related to intangible assets is expected to be as follows (in thousands):

9. BORROWING ARRANGEMENTS
LONG-TERM DEBT
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
51

Table of Contents
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"). As of September 30, 2011, $26.7 million aggregate principal amount of our 1.50% Notes remains outstanding. The Company pays interest in cash semi-annually in arrears on March 1 and September 1 of each year on the 1.50% Notes. The conversion price of the 1.50% Notes is 105.0696 shares per $1,000 principal amount of notes to be redeemed, which is the equivalent of a conversion price of approximately $9.52 per share, plus accrued and unpaid interest, if any, to the conversion date. Holders of the remaining $26.7 million aggregate principal balance of the 1.50% Notes may require the Company to repurchase the 1.50% Notes upon a change in control of the Company.
Holders may convert the 1.50% Notes at any time on or prior to the close of business on the final maturity date. If a holder of a 1.50% Note elects to convert such Notes at maturity, the Company may continue to choose to deliver to the holder either cash, shares of its common stock or a combination of cash and shares of its common stock to settle the conversion. This cash settlement provision permits the application of the treasury stock method in determining potential share dilution of the conversion spread should the share price of the Company's common stock exceed $9.52. It has been the Company’s historical practice to cash settle the principal and interest components of convertible debt instruments, and it is our intention to continue to do so in the future, including with respect to the 1.50% Notes.
As of September 30, 2011, the $26.1 million carrying value of the 1.50% Notes was deemed a current liability and accordingly was classified as short-term debt. Long-term debt consists of these convertible notes with a carrying value of $24.7 million as of October 1, 2010. As of September 30, 2011, using a closing price of our common stock of $17.96, the actual "if converted" value of the remaining 1.50% Notes was $50.3 million which exceeds the related principal amount by approximately $23.6 million. The actual amount of the cash premium will be calculated based on the 20 day average stock price prior to maturity.
On October 3, 2009, the Company adopted ASC 470-20 — Debt, Debt with Conversions and Other Options ("ASC 470-20"). which requires the issuer of convertible debt instruments with cash settlement features to separately account for the liability and equity components of the convertible debt instrument and requires retrospective application to all periods presented in the financial statements to which it is applicable. ASC 470-20 applies to the Company's 2007 Convertible Notes. Using a non-convertible borrowing rate of 6.86%, the Company estimated the fair value of the liability component of the $100.0 million aggregate principal amount of the 1.50% Notes to be $77.3 million as of October 3, 2009. As of the issuance date, the difference between the fair value of the liability component of the 1.50% Notes and the corresponding aggregate principal amount of such notes, which is equal to the fair value of the equity component of the 1.50% Notes, $22.7 million, was retrospectively recorded as a debt discount and as an increase to additional paid-in capital, net of tax. The discount of the liability component of the 1.50% Notes is being amortized over the life of the instrument.
During the fiscal year ending October 1, 2010, the Company redeemed the remaining $32.6 million of aggregate principal amount of the 1.25% Notes and redeemed $20.4 million of aggregate principal amount of the 1.50% Notes. The Company paid a cash premium (cash paid less principal amount) of $15.1 million and $12.4 million on the retirements of the 1.25% and 1.50% Notes, respectively. After applying ASC 470-20, the Company recorded a net loss on the transaction of approximately $0.1 million (including commissions and deferred financing).

SHORT-TERM DEBT
As of September 30, 2011, the $26.1 million carrying value of the 1.50% Notes was classified as short-term debt.
The Company's short-term debt balance as of October 1, 2010 consisted of a $50.0 million credit facility, which the Company repaid and terminated during the first quarter of fiscal 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.
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 30, 2011, the Company has maintained a valuation allowance of $39.4 million. This valuation allowance is comprised of $26.1 million related to U.S. State tax credits and $13.3 million related to foreign deferred tax assets of which $11.6 million are foreign deferred tax assets acquired from SiGe. If these benefits are recognized in a future period the valuation allowance on deferred tax assets will be reversed and up to a $39.0 million income tax benefit, and up to a $0.4 million reduction to goodwill may be recognized. The Company will need to generate $180.2 million of future United States federal taxable income to utilize our United States deferred tax assets as of September 30, 2011.
Based on the Company’s evaluation of the realizability of its United States net deferred tax assets and other future deductible items
55

Table of Contents
through the generation of future taxable income, during fiscal year 2010 the Company recognized a net decrease in its valuation allowance of $1.0 million. The change in the valuation allowance resulted in a tax expense of $2.8 million and an increase to additional paid-in capital of $3.8 million.
On February 20, 2009, the California governor signed into law tax legislation that permitted California taxpayers to apportion their income using a single sales factor apportionment formula for tax years beginning on or after January 1, 2011. As a result of this legislation, the Company recognized a net decrease to its deferred tax assets as of September 30, 2011 of $0.8 million, resulting in a corresponding tax expense.
The Mexican presidential decree allowing Mexican Maquiladoras to calculate their tax using an income based method was set to expire on December 31, 2011. Accordingly, the Company would then be required to use the alternative Flat Tax Regime to compute its annual tax. This resulted in a decrease in the Company's deferred tax assets of $1.1 million and a corresponding tax expense. After September 30, 2011, but prior to the release of the Company's financial statement, the Mexican Government extended the special tax incentives for Mexican Maquiladoras. As a result, the Company expects to recognize an increase to its deferred tax assets and a corresponding tax benefit in the first quarter of fiscal year 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 30, 2011, the Company has United States federal net operating loss carry forwards of approximately $60.5 million, including $43.3 million related to the acquisition of SiGe, which will expire at various dates through 2030 and aggregate state net operating loss carry forwards of approximately $1.3 million, which will expire at various dates through 2020. 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 and state income tax credit carry forwards of approximately $80.1 million, of which $23.0 million of federal income tax credit carry forwards have not been recorded as a deferred tax asset. The United States federal tax credits expire at various dates through 2031. 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 30, 2011, no provision has been made for United States federal, state, or additional foreign income taxes related to approximately $147.0 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 $32.1 million and $19.9 million as of September 30, 2011 and October 1, 2010, respectively. Of the total unrecognized tax benefits at September 30, 2011, $19.7 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):

Balance at October 1, 2010 | $ | 19,900 |
Increases based on positions related to prior years | 935 |
Increases based on positions related to current year | 11,334 |

The Company’s major tax jurisdictions as of September 30, 2011 are the United States, California, Iowa, Singapore and Canada. For the United States, the Company has open tax years dating back to fiscal year 1998 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.

Table of Contents
During the year ended September 30, 2011, the Company did not recognize any significant amount of previously unrecognized tax benefits related to the expiration of the statute of limitations. The Company's policy is to recognize accrued interest and penalties, if incurred, on any unrecognized tax benefits as a component of income tax expense. The Company recognized $0.5 million of accrued interest or penalties related to unrecognized tax benefits during fiscal year 2011.

Table of Contents

| Fiscal Years Ended
| September 30, 2011 |  | October 1, 2010 |  | October 2, 2009
Expected volatility | 49.26 | % |  | 56.19 | % |  | 60.90 | %
Risk free interest rate (7 year contractual life options) | 0.63 | % |  | 1.12 | % |  | 2.36 | %
Dividend yield | 0.00 |  |  | 0.00 |  |  | 0.00 |
Expected option life (7 year contractual life options) | 4.10 |  |  | 4.23 |  |  | 4.42 |

The Company used an arithmetic average of historical volatility and implied volatility to calculate its expected volatility during the year ended September 30, 2011. 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 employee's 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

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 annual eligible compensation. For the fiscal years ended September 30, 2011, October 1, 2010, and October 2, 2009, the Company contributed shares of 0.2 million, 0.3 million, and 0.7 million, respectively, and recognized expense of $5.5 million, $4.8 million, and $4.6 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, 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 assert in the future, patent, copyright, trademark and other intellectual property rights to technologies that are important to the Company's business and have demanded, and may demand in the future, 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 is also involved in legal proceedings in the ordinary course of business.
On May 26, 2011, the Company announced it had entered into an agreement and plan of merger (the “Merger Agreement”) with PowerCo Acquisition Corp., a wholly owned subsidiary of the Company (“Merger Sub”) and AATI pursuant to which the Merger Sub will, subject to the satisfaction or waiver of the conditions in the Merger Agreement, merge with and into AATI, and AATI will survive the merger and become a wholly owned subsidiary of the Company (the “Merger”). Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, each outstanding share of AATI common stock (except for shares held directly or indirectly by the Company, Merger Sub, AATI or any wholly owned subsidiary of AATI, and except for shares of AATI common stock held by stockholders exercising dissenter’s rights) will automatically be converted into the right to receive an aggregate of $6.13 per share.
Skyworks and AATI are parties to an arbitration proceeding, in which Skyworks is seeking to be released from its obligations to proceed with the transactions contemplated by the Merger Agreement and AATI is seeking to require Skyworks to consummate the transactions contemplated by the Merger Agreement. Skyworks' petition, filed on September 26, 2011 and thereafter amended, asserts claims against AATI for breach of Sections 5.1, 5.1(k), 5.1(n), 6.2 and 6.4 of the Merger Agreement and claims based on misrepresentations by AATI to Skyworks dating to before the signing of the Merger Agreement, and seeks an order (a) declaring that Skyworks is relieved of its obligations under the Merger Agreement, (b) declaring that Skyworks is entitled to terminate the Merger Agreement, and (c) in the alternative, awarding damages in an amount to be proven at final hearing. AATI's petition, filed by AATI on September 23, 2011, asserts claims against Skyworks for breach of the Merger Agreement and seeks (x) a declaratory judgment from the Court (i) that AATI has not breached the merger agreement, (ii) that no “material adverse effect” has occurred with respect to AATI, and (iii) that Skyworks has breached its obligations under the Merger Agreement, (y) an order of specific performance of the Merger Agreement compelling Skyworks to close the merger, and (z) in the alternative, damages in an amount to be proven at final hearing. The petitions have been consolidated for all purposes of the arbitration proceedings, and the hearing is currently scheduled to take place in the last week of November and the first week of December 2011. Under Delaware law, applicable stipulations and orders, and the applicable provisions of the Merger Agreement, the arbitration proceedings are confidential,

subject to the parties' disclosure obligations under federal securities law and other applicable laws. Skyworks is unable to predict the outcome of the proceedings.
On June 6, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202403) (the "Bushansky action") naming AATI, the members of AATI's board of directors, the Company and Merger Sub as defendants. The complaint alleges, among other things, (1) that the members of AATI's board of directors breached their fiduciary duties by (a) failing to take steps to maximize the value of the merger consideration to AATI's stockholders, (b) taking steps to avoid competitive bidding, and (c) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, and (2) that AATI, the members of AATI's board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The complaint seeks to enjoin consummation of the merger or, if the merger is completed, to recover damages caused by the alleged breaches of fiduciary duties. The complaint also seeks recovery of attorney's fees and costs of the lawsuit.
On June 7, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202501) (the "Venette action") naming AATI, the members of AATI's board of directors, the Company and Merger Sub as defendants. Plaintiffs filed an amended complaint on July 14, 2011 (the "Amended Complaint"). The Amended Complaint alleges, among other things, (1) that the members of AATI's board of directors breached their fiduciary duties by (a) agreeing to the merger for inadequate consideration on unfair terms, (b) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, (c) selling the company in response to alleged pressure from Dialectic Capital Partners, LP ("Dialectic"), (d) taking steps to avoid competitive bidding (including the entry by certain AATI officers and directors into agreements with the Company relating to voting commitments and inclusion in the merger agreement of nonsolicitation provisions and a termination fee), and (e) by causing the issuance of a materially misleading Form S-4 Registration Statement which, inter alia, purportedly fails to disclose material facts surrounding (i) Dialectic's impact on the proposed merger process, (ii) the AATI board of directors' evaluation of the Company and its offer for AATI, and (iii) supporting figures and analysis regarding the fairness opinion that the AATI Board obtained from its financial advisor, Needham & Company, LLC, in connection with the transaction and (2) that AATI, the members of AATI's board of directors, the Company and Merger Sub aided and abetted these purported breaches of fiduciary duties. The Amended Complaint seeks to enjoin consummation of the merger, and to have the court direct the defendants to implement procedures and processes to maximize shareholder value. The Amended Complaint also seeks recovery of attorney's fees and costs of the lawsuit.
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 the Amended Complaint as the operative complaint in the litigation. The Company believes that the claims in the consolidated action are without merit and intends to defend against such claims vigorously.
The Company believes there are no other litigation pending that will have, individually or in the aggregate, a material adverse effect on its business.
15. GUARANTEES AND INDEMNITIES
The Company has made no contractual guarantees for the benefit of third parties. However, the Company generally indemnifies its customers from third-party intellectual property infringement litigation claims related to its products, and, on occasion, also provides other indemnities related to product sales. In connection with certain facility leases, the Company has indemnified its lessors for certain claims arising from the facility or the lease.
The Company indemnifies its directors and officers to the maximum extent permitted under the laws of the state of Delaware. The duration of the indemnities varies, and in many cases is indefinite. The indemnities to customers in connection with product sales generally are subject to limits based upon the amount of the related product sales and in many cases are subject to geographic and other restrictions. In certain instances, the Company's indemnities do not provide for any limitation of the maximum potential future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities in the accompanying consolidated balance sheets and does not expect that such obligations will have a material adverse impact on its financial condition or results of operations.

Equity based awards exercisable for approximately 2.0 million, 4.6 million, and 16.5 million shares were outstanding but not included in the computation of earnings per share for the fiscal year ended September 30, 2011, October 1, 2010 and October 2, 2009, 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 acquisitions, the Company reassessed its operations and concluded that there has been no change and the Company continues to consider itself to have one reportable operating segment at September 30, 2011. 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.

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 both fiscal years 2011 and 2010 the Company had three customers, each with greater than ten percent of net revenue; Foxconn, Nokia and Samsung Electronics. In fiscal years 2009 the Company's greater than ten percent customers were Asian Information Technology, Samsung Electronics and Sony Ericsson Mobile Communications.
The Company's greater than ten percent customers comprised the following percentages of net revenue:

ITEM 9A. CONTROLS AND PROCEDURES.
Evaluation of disclosure controls and procedures.
Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2011. 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

Table of Contents
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 30, 2011, 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 30, 2011. 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 30, 2011, 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 acquisitions during the period, including SiGe Semiconductor which was acquired on June 10, 2011 whose financial statements constitute approximately 15.9% of total consolidated assets (of which 12.5% represents goodwill and intangible assets included within the scope of the assessment) and 2.8% of consolidated revenues as of and for the fiscal year ended September 30, 2011.
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.
