Silicon Laboratories Inc. designs and develops proprietary, analog-intensive, mixed-signal integrated circuits (ICs) for a broad range of applications. Mixed-signal ICs are electronic components that convert real-world analog signals, such as sound and radio waves, into digital signals that electronic products can process. Therefore, mixed-signal ICs are critical components in a broad range of applications in a variety of markets, including communications, consumer, industrial, automotive, medical and power management.
Our world-class, mixed-signal ICs use standard complementary metal oxide semiconductor (CMOS) technology to dramatically reduce the cost, size and system power requirements of devices that our customers sell to their end-user customers. Our expertise in analog-intensive, mixed-signal IC design in CMOS allows us to develop new and innovative products that are highly integrated, simplifying our customers' designs and improving their time-to-market.
Communications, computing and consumer electronics continue to drive semiconductor consumption. Growth in these markets has been driven primarily by the increasing pervasiveness of Internet usage, development of new communications technologies and the availability of improved communication services at lower costs over high-speed, highly reliable networks. This demand has fueled tremendous growth in the number of electronic devices. Demand for functionality in mobile, handheld devices such as mobile phones, portable media players and personal navigation devices, has increased as manufacturers attempt to further differentiate their products. Consumer and enterprise demand for Internet connectivity, the availability of alternative telephony services and the transition to digital video are also key trends driving demand for innovative, mixed-signal ICs.
All of these applications are characterized by an intersection between the analog world we live in and the digital world of computing, and therefore require analog-intensive, mixed-signal circuits. Traditional mixed-signal designs relied upon solutions built with numerous, complex discrete analog and digital components. While these traditional designs provide the required functionality, they are often inefficient and inadequate for use in markets where size, cost, power consumption and performance are increasingly important product differentiators. In order to improve their competitive position, electronics manufacturers need to reduce the cost and complexity of their systems and enable new features or functionality to differentiate themselves from their competitors.
Simultaneously, these manufacturers face accelerating time-to-market demands and must be able to rapidly adapt to evolving industry standards and new technologies. Because analog-intensive, mixed-signal IC design expertise is difficult to find, these manufacturers increasingly are turning to third parties, like us, to provide advanced mixed-signal solutions. Mixed-signal design requires specific expertise and relies on creative, experienced engineers to deliver solutions that optimize speed, power and performance despite the noisy digital environment and within the constraints of standard manufacturing processes. The development of this design expertise typically requires years of practical analog design experience under the guidance of a senior engineer, and engineers with the required level of skill and expertise are in short supply.
Many third-party IC providers lack sufficient analog expertise to develop compelling mixed-signal ICs. As a result, manufacturers of electronic devices value third-party providers that can supply them with mixed-signal ICs with greater functionality, smaller size and lower power requirements at a reduced cost and shorter time-to-market.
We provide analog-intensive, mixed-signal ICs for use in a variety of electronic products in a broad range of applications including portable devices, satellite set top boxes, AM/FM radios and other consumer electronics, networking equipment, test and measurement equipment, industrial monitoring and control, central office telephone equipment and customer premises equipment. Our products integrate complex mixed-signal functions that are frequently performed by numerous discrete components in competitive products into single chips or chipsets. By doing so, we are able to create products that when compared to many competing products:
We group our products into the following categories:
The following table summarizes the diverse product areas and applications for the various ICs that we have introduced to customers:
Our silicon DAA for PC modems provides the functionality of both a direct access arrangement and a codec in a single chipset. Our DSL Analog Front End (AFE) is designed to provide the connectivity functions for business or residential asymmetric digital subscriber line (ADSL) connection at the user end in customer premises equipment.
During fiscal 2009, 2008 and 2007, sales of our mixed-signal products accounted for substantially all of our revenue.
In March 2007, we sold our Aero® transceiver, AeroFONE single-chip phone and power amplifier product lines (the "Aero product lines") to NXP B.V. and NXP Semiconductors France SAS (collectively "NXP"). These products represented about one third of our quarterly revenue at the time of the divestiture. We intend to selectively compete in wireless applications and have retained a substantial portion of our core RF intellectual property.
Customers, Sales and Marketing
We market our products through our direct sales force and through a network of independent sales representatives and distributors. Direct and distributor customers buy on an individual purchase order basis, rather than pursuant to long-term agreements.
We consider our customer to be the end customer purchasing either directly from a distributor, a contract manufacturer or us. An end customer purchasing through a contract manufacturer typically instructs such contract manufacturer to obtain our products and incorporate such products with other components for sale by such contract manufacturer to the end customer. Although we actually sell the products to, and are paid by, the distributors and contract manufacturers, we refer to such end customer as our customer.
Two of our distributors, Edom Technology and Avnet, represented 27% and 10% of our revenues during fiscal 2009. Distributors are not considered end customers, but rather serve as a sales channel to our end customers. No other distributor accounted for 10% or more of revenues for fiscal 2009.
During fiscal 2009, our ten largest end customers accounted for 43% of our revenues. We had one end customer, Samsung, whose purchases across a variety of product areas represented 16% of our total revenues during fiscal 2009. No other single end customer accounted for more than 10% of our revenues during this period. Our major customers include 2Wire, Apple, Huawei, LG Electronics, Nokia, Philips, Samsung, Sony Ericsson, Thomson and Varian Medical Systems.
We maintain numerous sales offices in North America, Europe and Asia. Revenue is attributed to a geographic area based on the end customer's shipped-to location. The percentage of our revenues to customers located outside of the United States was 88% in fiscal 2009. For further information regarding our revenues and long-lived assets by geographic area, see Note 17, Segment Information, to the Consolidated Financial Statements for additional information.
Our direct sales force includes regional sales managers in the field and area business managers to further support customer communications. We also utilize independent sales representatives and distributors to generate sales of our products. We have relationships with many independent sales representatives and distributors worldwide whom we have selected based on their understanding of the mixed-signal IC marketplace and their ability to provide effective field sales applications support for our products.
Our marketing efforts are targeted at both identified industry leaders and emerging market participants. Direct marketing activities are supplemented by a focused marketing communications effort that seeks to raise awareness of our company and products. Our public relations efforts are focused on leading trade and business publications. Our external website is used to deliver corporate information and product information. We also pursue targeted advertising in key trade publications and we have a cooperative marketing program that allows our distributors and representatives to promote our products to their local markets in conjunction with their own advertising activities. Finally we maintain a presence at strategic trade shows and industry events. These activities, in combination with direct sales activities, help drive demand for our products.
Due to the complex and innovative nature of our ICs, we employ experienced applications engineers who work closely with customers to support the design-win process, and can significantly accelerate the customer's time required to bring a product to market. A design-win occurs when a customer has designed our ICs into its product architecture. A considerable amount of effort to assist the customer in incorporating our ICs into its products is typically required prior to any sale. In many cases, our innovative ICs require significantly different implementations than existing approaches and, therefore, successful implementations may require extensive communication with potential customers. The amount of time required to achieve a design-win can vary substantially depending on a customer's development cycle, which can be relatively short (such as three months) or very long (such as two years) based on a wide variety of customer factors. Not all design wins ultimately result in revenue. However, once a completed design architecture has been implemented and produced in high volumes, our customers are reluctant to significantly alter their designs due to this extensive design-win process. We believe this process, coupled with our intellectual property protection, promotes relatively longer product life cycles for our ICs and high barriers to entry for competitive products, even if such competing products are offered at lower prices. Finally, our close collaboration with our customers provides us with knowledge of derivative product ideas or completely new product line offerings that may not otherwise arise in other new product discussions.
Research and Development
Through our research and development efforts, we apply our experienced analog and mixed-signal engineering talent and expertise to create new ICs that integrate functions typically performed inefficiently by multiple discrete components. This integration generally results in lower costs, smaller die sizes, lower power demands and enhanced price/performance characteristics. We attempt to reuse successful techniques for integration in new applications where similar benefits can be realized. We believe that reliable and precise analog and mixed-signal ICs can only be developed by teams of engineers that coordinate their efforts under the direction of senior engineers who have significant analog experience and are familiar with the intricacies of designing these ICs for commercial volume production. The development of test methodologies is a critical activity in releasing a new product for commercial success. We believe that we have attracted some of the best engineers in our industry.
Research and development expenses were $104.4 million, $101.2 million and $89.3 million in fiscal 2009, 2008 and 2007, respectively.
Our product development process facilitates the design of highly-innovative, analog-intensive, mixed-signal ICs. Our engineers' deep knowledge of existing and emerging standards and performance requirements help us to assess the technical feasibility of a particular IC. We target areas where we can provide compelling product improvements. Once we have solved the primary challenges, our field application engineers continue to work closely with our customers' design teams to maintain and develop an understanding of our customers' needs, allowing us to formulate derivative products and refined features.
In providing mixed-signal ICs for our customers, we believe our key competitive advantages are:
To fully capitalize on these advantages, we have assembled a world-class development team with exceptional analog and mixed-signal design expertise led by accomplished senior engineers.
Analog Design Expertise in CMOS
We believe that our most significant core competency is world-class analog design capability. Additionally, we strive to design substantially all of our ICs in standard CMOS processes. There are several modern process technologies for manufacturing semiconductors including CMOS, Bipolar, BiCMOS, silicon germanium and gallium arsenide. While it is significantly more difficult to design analog ICs in CMOS, CMOS provides multiple benefits versus existing alternatives, including significantly reduced cost, reduced technology risk and greater worldwide foundry capacity. CMOS is the most commonly used process technology for manufacturing digital ICs and as a result is most likely to be used for the manufacturing of ICs with finer line geometries. These finer line geometries can enable smaller and faster ICs. By designing our ICs in CMOS, we enable our products to benefit from this trend towards finer line geometries, which allows us to integrate more digital functionality into our mixed-signal ICs.
Designing analog and mixed-signal ICs is significantly more complicated than designing stand alone digital ICs. While advanced software tools exist to help automate digital IC design, there are far fewer tools for advanced analog and mixed-signal IC design. In many cases, our analog circuit design efforts
begin at the fundamental transistor level. We believe that we have a demonstrated ability to design the most difficult analog and RF circuits using standard CMOS technologies. For example, our ProSLIC product family integrates subscriber line interface circuit (SLIC), codec and battery generation functionality into a single low-voltage CMOS IC.
Digital Signal Processing Design Expertise
We consider the partitioning of a circuit's functionality to be a proprietary and creative design technique. Our digital signal processing design expertise maximizes the price/performance characteristics of both the analog and digital functions and allows our ICs to work in an optimized manner to accomplish particular tasks. Generally, we surround core analog circuitry with digital CMOS transistors, which allow our ICs to perform the required analog functions with increased digital capabilities. For example, our broadcast audio products use a proven digital low-IF receiver and transmitter architecture to deliver superior RF performance and interference rejection compared to traditional, analog-only approaches. Digital signal processing is utilized to optimize sound quality under varying signal conditions, enabling a better consumer experience.
Microcontroller and System on a Chip Design Expertise
We have expanded our system on a chip expertise to include the talent and circuit integration methodologies required to combine precision analog, high-speed digital, flash memory and in-system programmability into a single, monolithic CMOS integrated circuit. Our microcontroller products are designed to capture an external analog signal, convert it to a digital signal, compute digital functions on the stream of data and then communicate the results through a standard digital interface. The ability to develop standard products with the broadest possible customer application base while being cost efficient with the silicon area of the monolithic CMOS integrated circuit requires a keen sense of customer value and engineering capabilities. Additionally, to manage the wide variety of signals on a monolithic piece of silicon including electrical noise, harmonics and other electronic distortions requires a fundamental knowledge of device physics and accumulated design expertise.
Understanding of Systems Technology and Trends
Our focused expertise in mixed-signal ICs is the result of the breadth of engineering talent we have assembled with experience working in analog-intensive CMOS design for a wide variety of applications. This expertise, which we consider a competitive advantage, is the foundation of our in-depth understanding of the technology and trends that impact electronic systems and markets. Our expertise includes:
Our understanding of the role of analog/digital interfaces within electronic systems, standards evolution, and end market drivers enables us to identify product development opportunities and capitalize on market trends.
As a fabless IC manufacturer, we conduct IC design and development in our facilities and electronically transfer our proprietary IC designs to third-party semiconductor fabricators who process silicon wafers to produce the ICs that we design. Our IC designs typically use industry-standard CMOS manufacturing process technology to achieve a level of performance normally associated with more expensive special-purpose IC fabrication technology. We believe the use of CMOS technology facilitates the rapid production of our ICs within a lower cost framework. Our IC production employs submicron process geometries which are readily available from leading foundry suppliers worldwide, thus increasing the likelihood that manufacturing capacity will be available throughout our products' life cycles. We currently partner principally with Taiwan Semiconductor Manufacturing Co. (TSMC) or its affiliates to manufacture our semiconductor wafers. We believe that our fabless manufacturing model significantly reduces our capital requirements and allows us to focus our resources on design, development and marketing of our ICs.
Once the silicon wafers have been produced, they are shipped directly to our third-party assembly subcontractors. The assembled ICs are then moved to the final testing stage. This operation can be performed by the same contractor that assembled the IC, other third-party test subcontractors or within our internal facilities prior to shipping to our customers. During fiscal 2009, the vast majority of our units shipped were tested by offshore third-party test subcontractors. We expect that our utilization of offshore third-party test subcontractors will remain at about this level during fiscal 2010.
As of January 2, 2010, our backlog was approximately $74.2 million, compared to approximately $45.8 million as of January 3, 2009. We include in backlog accepted product purchase orders from customers and worldwide distributor stocking orders. We only include orders with an expected shipping date from us within six months. Product orders in our backlog are subject to changes in delivery schedules or cancellation at the option of the purchaser typically without penalty. Our backlog may fluctuate significantly depending upon customer order patterns which may, in turn, vary considerably based on rapidly changing business circumstances. Shipments to distributors are not recognized as revenue until the products are sold by the distributors. Additionally, our arrangements with distributors typically provide for price protection and stock rotation activities. Accordingly, we do not believe that our backlog at any time is necessarily representative of actual sales for any succeeding period.
The markets for semiconductors generally, and for analog and mixed-signal ICs in particular, are intensely competitive. We anticipate that the market for our products will continually evolve and will be subject to rapid technological change. We believe the principal competitive factors in our industry are:
We believe that we are competitive with respect to these factors, particularly because our ICs typically are smaller in size, are highly integrated, achieve high performance specifications at lower price points than competitive products and are manufactured in standard CMOS which generally enables us to supply them on a relatively rapid basis to customers to meet their product introduction schedules. However, disadvantages we face include our relatively short operating history in certain of
our markets and the need for customers to redesign their products and modify their software to implement our ICs in their products.
As we target and supply products to numerous markets and applications, we face competition from a relatively large number of competitors. We compete with Analog Devices, Atmel, Broadcom, Conexant, Cypress, Epson, Freescale, IDT, Lantiq, LSI, Maxim Integrated Products, Microchip, NXP Semiconductors, Renesas, Sony Semiconductor, ST-Ericsson, STMicroelectronics, Texas Instruments, Vectron International, Zarlink Semiconductor and others. We expect to face competition in the future from our current competitors, other manufacturers and designers of semiconductors and start-up semiconductor design companies. Our competitors may also offer bundled solutions offering a more complete product, which may negatively impact our competitive position despite the technical merits or advantages of our products. In addition, our customers could develop products or technologies internally that would replace their need for our products and would become a source of competition. As the markets for electronic products grow, we also may face competition from traditional electronic device companies. These companies may enter the mixed-signal semiconductor market by introducing their own products, including components within their products that would eliminate the need for our ICs, or by entering into strategic relationships with or acquiring other existing IC providers.
Many of our competitors and potential competitors have longer operating histories, greater name recognition, access to larger customer bases, complementary product offerings, and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than us. Current and potential competitors have established or may establish financial and strategic relationships between themselves or with our existing or potential customers, resellers or other third parties. Accordingly, it is possible that new competitors or alliances among competitors could emerge and rapidly acquire significant market share.
Our future success depends in part upon our proprietary technology. We seek to protect our technology through a combination of patents, copyrights, trade secrets, trademarks and confidentiality procedures. As of January 2, 2010, we had approximately 900 issued or pending United States patents in the IC field. We also frequently file for patent protection in a variety of international jurisdictions with respect to the proprietary technology covered by our U.S. patents and patent applications. There can be no assurance that patents will ever be issued with respect to these applications. Furthermore, it is possible that any patents held by us may be invalidated, circumvented, challenged or licensed to others. In addition, there can be no assurance that such patents will provide us with competitive advantages or adequately safeguard our proprietary rights. While we continue to file new patent applications with respect to our recent developments, existing patents are granted for prescribed time periods and will expire at various times in the future.
We claim copyright protection for proprietary documentation for our products. We have filed for registration, or are in the process of filing for registration, the visual images of certain ICs with the U.S. Copyright Office. We have registered the "Silicon Labs" logo and a variety of other product and product family names as trademarks in the United States and selected foreign jurisdictions. All other trademarks, service marks or trade names appearing in this report are the property of their respective owners. We also attempt to protect our trade secrets and other proprietary information through agreements with our customers, suppliers, employees and consultants, and through other customary security measures. We intend to protect our rights vigorously, but there can be no assurance that our efforts will be successful. In addition, the laws of other countries in which our products are sold may not protect our products and intellectual property rights to the same extent as the laws of the United States.
While our ability to effectively compete depends in large part on our ability to protect our intellectual property, we believe that our technical expertise and ability to introduce new products in a timely manner will be an important factor in maintaining our competitive position.
Many participants in the semiconductor and electronics industries have a significant number of patents and have frequently demonstrated a readiness to commence litigation based on allegations of patent and other intellectual property infringement. From time to time, third parties may assert infringement claims against us. We may not prevail in any such litigation or may not be able to license any valid and infringed patents from third parties on commercially reasonable terms, if at all. Litigation, regardless of the outcome, is likely to result in substantial cost and diversion of our resources, including our management's time. Any such litigation could materially adversely affect us. For further information regarding patent litigation, please see Part I, Item 3. Legal Proceedings.
Our licenses include industry standard licenses with our vendors, such as wafer fabrication tool libraries, third party core libraries, computer-aided design applications and business software applications.
As of January 2, 2010, we employed 736 people. Our success depends on the continued service of our key technical and senior management personnel and on our ability to continue to attract, retain and motivate highly skilled analog and mixed-signal engineers. The competition for such personnel is intense. We have never had a work stoppage and none of our U.S. employees are represented by a labor organization. We consider our employee relations to be good.
Federal, state and local regulations impose various environmental controls on the storage, use, discharge and disposal of certain chemicals and gases used in the semiconductor industry. Our compliance with these laws and regulations has not had a material impact on our financial position or results of operations.

Risks Related to our Business
We may not be able to maintain our historical growth and may experience significant period-to-period fluctuations in our revenues and operating results, which may result in volatility in our stock price
Although we have generally experienced revenue growth in our history, we may not be able to sustain this growth. We may also experience significant period-to-period fluctuations in our revenues and operating results in the future due to a number of factors, and any such variations may cause our stock price to fluctuate. In some future period our revenues or operating results may be below the expectations of public market analysts or investors. If this occurs, our stock price may drop, perhaps significantly.
A number of factors, in addition to those cited in other risk factors applicable to our business, may contribute to fluctuations in our revenues and operating results, including:
The markets for mobile handsets, consumer electronics, satellite set-top boxes and VoIP applications are characterized by rapid fluctuations in demand and seasonality that result in corresponding fluctuations in the demand for our products that are incorporated in such devices. Additionally, the rate of technology acceptance by our customers results in fluctuating demand for our products as customers are reluctant to incorporate a new IC into their products until the new IC has
achieved market acceptance. Once a new IC achieves market acceptance, demand for the new IC can quickly accelerate to a point and then level off such that rapid historical growth in sales of a product should not be viewed as indicative of continued future growth. In addition, demand can quickly decline for a product when a new IC product is introduced and receives market acceptance. Due to the various factors mentioned above, the results of any prior quarterly or annual periods should not be relied upon as an indication of our future operating performance.
If we are unable to develop or acquire new and enhanced products that achieve market acceptance in a timely manner, our operating results and competitive position could be harmed
Our future success will depend on our ability to reduce our dependence on a few products by developing or acquiring new ICs and product enhancements that achieve market acceptance in a timely and cost-effective manner. The development of mixed-signal ICs is highly complex, and we have at times experienced delays in completing the development and introduction of new products and product enhancements. Successful product development and market acceptance of our products depend on a number of factors, including:
We cannot provide any assurance that products which we recently have developed or may develop in the future will achieve market acceptance. We have introduced to market or are in development of many ICs. If our ICs fail to achieve market acceptance, or if we fail to develop new products on a timely basis that achieve market acceptance, our growth prospects, operating results and competitive position could be adversely affected.
Our research and development efforts are focused on a limited number of new technologies and products, and any delay in the development, or abandonment, of these technologies or products by industry participants, or their failure to achieve market acceptance, could compromise our competitive position
Our ICs are used as components in electronic devices in various markets. As a result, we have devoted and expect to continue to devote a large amount of resources to develop products based on new and emerging technologies and standards that will be commercially introduced in the future.
Research and development expense in fiscal 2009 was $104.4 million, or 23.7% of revenues. A number of large companies are actively involved in the development of these new technologies and standards. Should any of these companies delay or abandon their efforts to develop commercially available products based on new technologies and standards, our research and development efforts with respect to these technologies and standards likely would have no appreciable value. In addition, if we do not correctly anticipate new technologies and standards, or if the products that we develop based on these new technologies and standards fail to achieve market acceptance, our competitors may be better able to address market demand than we would. Furthermore, if markets for these new technologies and standards develop later than we anticipate, or do not develop at all, demand for our products that are currently in development would suffer, resulting in lower sales of these products than we currently anticipate.
We depend on a limited number of customers for a substantial portion of our revenues, and the loss of, or a significant reduction in orders from, any key customer could significantly reduce our revenues
The loss of any of our key customers, or a significant reduction in sales to any one of them, would significantly reduce our revenues and adversely affect our business. During fiscal 2009, our ten largest customers accounted for 43% of our revenues. During fiscal 2009, Samsung's purchases across a variety of product areas represented 16% of our total revenues. Some of the markets for our products are dominated by a small number of potential customers. Therefore, our operating results in the foreseeable future will continue to depend on our ability to sell to these dominant customers, as well as the ability of these customers to sell products that incorporate our IC products. In the future, these customers may decide not to purchase our ICs at all, purchase fewer ICs than they did in the past or alter their purchasing patterns, particularly because:
While we have been a significant supplier of ICs used in many of our customers' products, our customers regularly evaluate alternative sources of supply in order to diversify their supplier base, which increases their negotiating leverage with us and protects their ability to secure these components. We believe that any expansion of our customers' supplier bases could have an adverse effect on the prices we are able to charge and volume of product that we are able to sell to our customers, which would negatively affect our revenues and operating results.
Significant litigation over intellectual property in our industry may cause us to become involved in costly and lengthy litigation which could seriously harm our business
In recent years, there has been significant litigation in the United States involving patents and other intellectual property rights. From time to time, we receive letters from various industry participants alleging infringement of patents, trademarks or misappropriation of trade secrets or from customers requesting indemnification for claims brought against them by third parties. The exploratory nature of these inquiries has become relatively common in the semiconductor industry. We respond when we deem appropriate and as advised by legal counsel. We have been involved in litigation to
protect our intellectual property rights in the past and may become involved in such litigation again in the future. In the future, we may become involved in additional litigation to defend allegations of infringement asserted by others, both directly and indirectly as a result of certain industry-standard indemnities we may offer to our customers. Legal proceedings could subject us to significant liability for damages or invalidate our proprietary rights. Legal proceedings initiated by us to protect our intellectual property rights could also result in counterclaims or countersuits against us. Any litigation, regardless of its outcome, would likely be time-consuming and expensive to resolve and would divert our management's time and attention. Most intellectual property litigation also could force us to take specific actions, including:
We may be unable to protect our intellectual property, which would negatively affect our ability to compete
Our products rely on our proprietary technology, and we expect that future technological advances made by us will be critical to sustain market acceptance of our products. Therefore, we believe that the protection of our intellectual property rights is and will continue to be important to the success of our business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We also enter into confidentiality or license agreements with our employees, consultants, intellectual property providers and business partners, and control access to and distribution of our documentation and other proprietary information. Despite these efforts, unauthorized parties may attempt to copy or otherwise obtain and use our proprietary technology. Monitoring unauthorized use of our technology is difficult, and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. We cannot be certain that patents will be issued as a result of our pending applications nor can we be certain that any issued patents would protect or benefit us or give us adequate protection from competing products. For example, issued patents may be circumvented or challenged and declared invalid or unenforceable. We also cannot be certain that others will not develop effective competing technologies on their own.
Failure to manage our distribution channel relationships could impede our future growth
The future growth of our business will depend in large part on our ability to manage our relationships with current and future distributors and sales representatives, develop additional channels for the distribution and sale of our products and manage these relationships. As we execute our indirect sales strategy, we must manage the potential conflicts that may arise with our direct sales efforts. For example, conflicts with a distributor may arise when a customer begins purchasing directly from us rather than through the distributor. The inability to successfully execute or manage a multi-channel sales strategy could impede our future growth. In addition, relationships with our distributors often involve the use of price protection and inventory return rights. This often requires a significant amount of sales management's time and system resources to manage properly.
We are subject to increased inventory risks and costs because we build our products based on forecasts provided by customers before receiving purchase orders for the products
In order to ensure availability of our products for some of our largest customers, we start the manufacturing of our products in advance of receiving purchase orders based on forecasts provided by these customers. However, these forecasts do not represent binding purchase commitments and we do not recognize sales for these products until they are shipped to the customer. As a result, we incur inventory and manufacturing costs in advance of anticipated sales. Because demand for our products may not materialize, manufacturing based on forecasts subjects us to increased risks of high inventory carrying costs, increased obsolescence and increased operating costs. These inventory risks are exacerbated when our customers purchase indirectly through contract manufacturers or hold component inventory levels greater than their consumption rate because this causes us to have less visibility regarding the accumulated levels of inventory for such customers. A resulting write-off of unusable or excess inventories would adversely affect our operating results.
Our products are complex and may contain errors which could lead to product liability, an increase in our costs and/or a reduction in our revenues
Our products are complex and may contain errors, particularly when first introduced or as new versions are released. Our new products are increasingly being designed in more complex processes which further increases the risk of errors. We rely primarily on our in-house testing personnel to design test operations and procedures to detect any errors prior to delivery of our products to our customers. Because our products are manufactured by third parties, should problems occur in the operation or performance of our ICs, we may experience delays in meeting key introduction dates or scheduled delivery dates to our customers. These errors also could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations and business reputation problems. Any defects could require product replacement or recall or we could be obligated to accept product returns. Any of the foregoing could impose substantial costs and harm our business.
Product liability claims may be asserted with respect to our products. Our products are typically sold at prices that are significantly lower than the cost of the end-products into which they are incorporated. A defect or failure in our product could cause failure in our customer's end-product, so we could face claims for damages that are disproportionately higher than the revenues and profits we receive from the products involved. Furthermore, product liability risks are particularly significant with respect to medical and automotive applications because of the risk of serious harm to users of these products. There can be no assurance that any insurance we maintain will sufficiently protect us from any such claims.
Any acquisitions we make could disrupt our business and harm our financial condition
As part of our growth and product diversification strategy, we continue to evaluate opportunities to acquire other businesses, intellectual property or technologies that would complement our current offerings, expand the breadth of our markets or enhance our technical capabilities. The acquisitions that we have made and may make in the future, including our acquisition of Integration Associates, entail a number of risks that could materially and adversely affect our business and operating results, including:
Future acquisitions also could cause us to incur debt or contingent liabilities or cause us to issue equity securities that could negatively impact the ownership percentages of existing shareholders.
Our customers require our products to undergo a lengthy and expensive qualification process without any assurance of product sales
Prior to purchasing our products, our customers require that our products undergo an extensive qualification process, which involves testing of the products in the customer's system as well as rigorous reliability testing. This qualification process may continue for six months or longer. However, qualification of a product by a customer does not ensure any sales of the product to that customer. Even after successful qualification and sales of a product to a customer, a subsequent revision to the IC or software, changes in the IC's manufacturing process or the selection of a new supplier by us may require a new qualification process, which may result in delays and in us holding excess or obsolete inventory. After our products are qualified, it can take an additional six months or more before the customer commences volume production of components or devices that incorporate our products. Despite these uncertainties, we devote substantial resources, including design, engineering, sales, marketing and management efforts, toward qualifying our products with customers in anticipation of sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, such failure or delay would preclude or delay sales of such product to the customer, which may impede our growth and cause our business to suffer.
We have increased our international activities significantly and plan to continue such efforts, which subjects us to additional business risks including increased logistical and financial complexity, political instability and currency fluctuations
We have established additional international subsidiaries and have opened additional offices in international markets to expand our international activities in Europe and Asia. This has included the establishment of a headquarters in Singapore for non-U.S. operations. The percentage of our revenues derived from customers located outside of the United States was 88% during fiscal 2009. We may not be able to maintain or increase international market demand for our products. Our international operations are subject to a number of risks, including:
To date, all of our sales to international customers and purchases of components from international suppliers have been denominated in U.S. dollars. As a result, an increase in the value of the U.S. dollar relative to foreign currencies could make our products more expensive for our international customers to purchase, thus rendering our products less competitive.
We rely on third parties to manufacture, assemble and test our products and the failure to successfully manage our relationships with our manufacturers and subcontractors would negatively impact our ability to sell our products
We do not have our own wafer fab manufacturing facilities. Therefore, we rely on third-party vendors to manufacture the ICs we design. We also currently rely on Asian third-party assembly subcontractors to assemble and package the silicon chips provided by the wafers for use in final products. Additionally, we rely on these offshore subcontractors for a substantial portion of the testing requirements of our products prior to shipping. We expect utilization of third-party subcontractors to continue in the future.
The cyclical nature of the semiconductor industry drives wide fluctuations in available capacity at third-party vendors. On occasion, we have been unable to adequately respond to unexpected increases in customer demand due to capacity constraints and, therefore, were unable to benefit from this incremental demand. We may be unable to obtain adequate foundry, assembly or test capacity from our third-party subcontractors to meet our customers' delivery requirements even if we adequately forecast customer demand.
There are significant risks associated with relying on these third-party foundries and subcontractors, including:
We typically do not have long-term supply contracts with our third-party vendors which obligate the vendor to perform services and supply products to us for a specific period, in specific quantities, and at specific prices. Our third-party foundry, assembly and test subcontractors typically do not guarantee that adequate capacity will be available to us within the time required to meet demand for
our products. In the event that these vendors fail to meet our demand for whatever reason, we expect that it would take up to 12 months to transition performance of these services to new providers. Such a transition may also require qualification of the new providers by our customers or their end customers.
Since our inception, most of the silicon wafers for the products that we have shipped were manufactured either by TSMC or its affiliates. Our customers typically complete their own qualification process. If we fail to properly balance customer demand across the existing semiconductor fabrication facilities that we utilize or are required by our foundry partners to increase, or otherwise change the number of fab lines that we utilize for our production, we might not be able to fulfill demand for our products and may need to divert our engineering resources away from new product development initiatives to support the fab line transition, which would adversely affect our operating results.
Our products incorporate technology licensed from third parties
We incorporate technology (including software) licensed from third parties in our products. We could be subjected to claims of infringement regardless of our lack of involvement in the development of the licensed technology. Although a third party licensor is typically obligated to indemnify us if the licensed technology infringes on another party's intellectual property rights, such indemnification is typically limited in amount and may be worthless if the licensor becomes insolvent. See Significant litigation over intellectual property in our industry may cause us to become involved in costly and lengthy litigation which could seriously harm our business. Furthermore, any failure of third party technology to perform properly would adversely affect sales of our products incorporating such technology.
Our inability to manage growth could materially and adversely affect our business
Our past growth has placed, and any future growth of our operations will continue to place, a significant strain on our management personnel, systems and resources. We anticipate that we will need to implement a variety of new and upgraded sales, operational and financial enterprise-wide systems, information technology infrastructure, procedures and controls, including the improvement of our accounting and other internal management systems to manage this growth and maintain compliance with regulatory guidelines, including Sarbanes-Oxley Act requirements. To the extent our business grows, our internal management systems and processes will need to improve to ensure that we remain in compliance. We also expect that we will need to continue to expand, train, manage and motivate our workforce. All of these endeavors will require substantial management effort, and we anticipate that we will require additional management personnel and internal processes to manage these efforts and to plan for the succession from time to time of certain persons who have been key management and technical personnel. If we are unable to effectively manage our expanding global operations, including our international headquarters in Singapore, our business could be materially and adversely affected.
We are subject to risks relating to product concentration
We derive a substantial portion of our revenues from a limited number of products, and we expect these products to continue to account for a large percentage of our revenues in the near term. Continued market acceptance of these products, is therefore, critical to our future success. In addition, substantially all of our products that we have sold include technology related to one or more of our issued U.S. patents. If these patents are found to be invalid or unenforceable, our competitors could introduce competitive products that could reduce both the volume and price per unit of our products. Our business, operating results, financial condition and cash flows could therefore be adversely affected by:
We are subject to credit risks related to our accounts receivable
We do not generally obtain letters of credit or other security for payment from customers, distributors or contract manufacturers. Accordingly, we are not protected against accounts receivable default or bankruptcy by these entities. The current economic situation could increase the likelihood of such defaults and bankruptcies. Our ten largest customers or distributors represent a substantial majority of our accounts receivable. If any such customer or distributor, or a material portion of our smaller customers or distributors, were to become insolvent or otherwise not satisfy their obligations to us, we could be materially harmed.
We depend on our key personnel to manage our business effectively in a rapidly changing market, and if we are unable to retain our current personnel and hire additional personnel, our ability to develop and successfully market our products could be harmed
We believe our future success will depend in large part upon our ability to attract and retain highly skilled managerial, engineering, sales and marketing personnel. We believe that our future success will be dependent on retaining the services of our key personnel, developing their successors and certain internal processes to reduce our reliance on specific individuals, and on properly managing the transition of key roles when they occur. There is currently a shortage of qualified personnel with significant experience in the design, development, manufacturing, marketing and sales of analog and mixed-signal ICs. In particular, there is a shortage of engineers who are familiar with the intricacies of the design and manufacturability of analog elements, and competition for such personnel is intense. Our key technical personnel represent a significant asset and serve as the primary source for our technological and product innovations. We may not be successful in attracting and retaining sufficient numbers of technical personnel to support our anticipated growth. The loss of any of our key employees or the inability to attract or retain qualified personnel both in the United States and internationally, including engineers, sales, applications and marketing personnel, could delay the development and introduction of, and negatively impact our ability to sell, our products.
Any dispositions we make could harm our financial condition
In connection with our sale of the Aero product lines, we incurred various risks. This disposition and any disposition that we may make in the future entail a number of risks that could materially and adversely affect our business and operating results, including:
Our stock price may be volatile
The market price of our common stock has been volatile in the past and may be volatile in the future. The market price of our common stock may be significantly affected by the following factors:
The stock market has experienced extreme volatility that often has been unrelated to the performance of particular companies. These market fluctuations may cause our stock price to fall regardless of our performance.
Most of our current manufacturers, assemblers, test service providers, distributors and customers are concentrated in the same geographic region, which increases the risk that a natural disaster, epidemic, labor strike, war or political unrest could disrupt our operations or sales
Most of TSMC's foundries and several of our assembly and test subcontractors' sites are located in Taiwan and our other assembly and test subcontractors are located in the Pacific Rim region. In addition, many of our customers are located in the Pacific Rim region. The risk of earthquakes in Taiwan and the Pacific Rim region is significant due to the proximity of major earthquake fault lines in the area. Earthquakes, fire, flooding, lack of water or other natural disasters, an epidemic, political unrest, war, labor strikes or work stoppages in countries where our semiconductor manufacturers, assemblers and test subcontractors are located, likely would result in the disruption of our foundry, assembly or test capacity. There can be no assurance that alternate capacity could be obtained on favorable terms, if at all.
A natural disaster, epidemic, labor strike, war or political unrest where our customers' facilities are located would likely reduce our sales to such customers. North Korea's geopolitical maneuverings have created unrest. Such unrest could create economic uncertainty or instability, could escalate to war or otherwise adversely affect South Korea and our South Korean customers and reduce our sales to such
customers, which would materially and adversely affect our operating results. In addition, a significant portion of the assembly and testing of our products occurs in South Korea. Any disruption resulting from these events could also cause significant delays in shipments of our products until we are able to shift our manufacturing, assembling or testing from the affected subcontractor to another third-party vendor.
The semiconductor manufacturing process is highly complex and, from time to time, manufacturing yields may fall below our expectations, which could result in our inability to satisfy demand for our products in a timely manner and may decrease our gross margins due to higher unit costs
The manufacturing of our products is a highly complex and technologically demanding process. Although we work closely with our foundries and assemblers to minimize the likelihood of reduced manufacturing yields, we have from time to time experienced lower than anticipated manufacturing yields. Changes in manufacturing processes or the inadvertent use of defective or contaminated materials could result in lower than anticipated manufacturing yields or unacceptable performance deficiencies, which could lower our gross margins. If our foundries fail to deliver fabricated silicon wafers of satisfactory quality in a timely manner, we will be unable to meet our customers' demand for our products in a timely manner, which would adversely affect our operating results and damage our customer relationships.
We depend on our customers to support our products, and some of our customers offer competing products
Our products are currently used by our customers to produce modems, telephony equipment, mobile handsets, networking equipment and a broad range of other devices. We rely on our customers to provide hardware, software, intellectual property indemnification and other technical support for the products supplied by our customers. If our customers do not provide the required functionality or if our customers do not provide satisfactory support for their products, the demand for these devices that incorporate our products may diminish or we may otherwise be materially adversely affected. Any reduction in the demand for these devices would significantly reduce our revenues.
In certain products, some of our customers offer their own competitive products. These customers may find it advantageous to support their own offerings in the marketplace in lieu of promoting our products.
We could seek to raise additional capital in the future through the issuance of equity or debt securities, but additional capital may not be available on terms acceptable to us, or at all
We believe that our existing cash, cash equivalents and investments will be sufficient to meet our working capital needs, capital expenditures, investment requirements and commitments for at least the next 12 months. However, it is possible that we may need to raise additional funds to finance our activities or to facilitate acquisitions of other businesses, products, intellectual property or technologies. We believe we could raise these funds, if needed, by selling equity or debt securities to the public or to selected investors. In addition, even though we may not need additional funds, we may still elect to sell additional equity or debt securities or obtain credit facilities for other reasons. However, we may not be able to obtain additional funds on favorable terms, or at all. If we decide to raise additional funds by issuing equity or convertible debt securities, the ownership percentages of existing shareholders would be reduced.
We are a relatively small company with limited resources compared to some of our current and potential competitors and we may not be able to compete effectively and increase market share
Some of our current and potential competitors have longer operating histories, significantly greater resources and name recognition and a larger base of customers than we have. As a result, these competitors may have greater credibility with our existing and potential customers. They also may be able to adopt more aggressive pricing policies and devote greater resources to the development, promotion and sale of their products than we can to ours. In addition, some of our current and potential competitors have already established supplier or joint development relationships with the decision makers at our current or potential customers. These competitors may be able to leverage their existing relationships to discourage their customers from purchasing products from us or persuade them to replace our products with their products. Our competitors may also offer bundled chipset kit arrangements offering a more complete product despite the technical merits or advantages of our products. These competitors may elect not to support our products which could complicate our sales efforts. These and other competitive pressures may prevent us from competing successfully against current or future competitors, and may materially harm our business. Competition could decrease our prices, reduce our sales, lower our gross margins and/or decrease our market share.
Provisions in our charter documents and Delaware law could prevent, delay or impede a change in control of us and may reduce the market price of our common stock
Provisions of our certificate of incorporation and bylaws could have the effect of discouraging, delaying or preventing a merger or acquisition that a stockholder may consider favorable. For example, our certificate of incorporation and bylaws provide for:
We also are subject to the anti-takeover laws of Delaware which may discourage, delay or prevent someone from acquiring or merging with us, which may adversely affect the market price of our common stock.
Risks related to our industry
We are subject to the cyclical nature of the semiconductor industry, which has been subject to significant fluctuations
The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence and price erosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand. The industry has experienced significant fluctuations, often connected with, or in anticipation of, maturing product cycles and new product introductions of both semiconductor companies' and their customers' products and fluctuations in general economic conditions. Deteriorating general worldwide economic conditions, including
reduced economic activity, concerns about credit and inflation, increased energy costs, decreased consumer confidence, reduced corporate profits, decreased spending and similar adverse business conditions, would make it very difficult for our customers, our vendors, and us to accurately forecast and plan future business activities and could cause U.S. and foreign businesses to slow spending on our products. We cannot predict the timing, strength, or duration of any economic slowdown or economic recovery. If the economy or markets in which we operate deteriorate, our business, financial condition, and results of operations would likely be materially and adversely affected.
Downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. We believe the semiconductor industry has suffered a downturn due in large part to adverse conditions in the global credit and financial markets, including diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increased unemployment rates and general uncertainty regarding the economy. Such downturns may have a material adverse effect on our business and operating results.
Upturns have been characterized by increased product demand and production capacity constraints created by increased competition for access to third-party foundry, assembly and test capacity. We are dependent on the availability of such capacity to manufacture, assemble and test our ICs. None of our third-party foundry, assembly or test subcontractors have provided assurances that adequate capacity will be available to us.
The average selling prices of our products could decrease rapidly which may negatively impact our revenues and gross margins
We may experience substantial period-to-period fluctuations in future operating results due to the erosion of our average selling prices. We have reduced the average unit price of our products in anticipation of or in response to competitive pricing pressures, new product introductions by us or our competitors and other factors. If we are unable to offset any such reductions in our average selling prices by increasing our sales volumes, increasing our sales content per application or reducing production costs, our gross margins and revenues will suffer. To maintain our gross margin percentage, we will need to develop and introduce new products and product enhancements on a timely basis and continually reduce our costs. Our failure to do so could cause our revenues and gross margin percentage to decline.
Competition within the numerous markets we target may reduce sales of our products and reduce our market share
The markets for semiconductors in general, and for mixed-signal ICs in particular, are intensely competitive. We expect that the market for our products will continually evolve and will be subject to rapid technological change. In addition, as we target and supply products to numerous markets and applications, we face competition from a relatively large number of competitors. We compete with Analog Devices, Atmel, Broadcom, Conexant, Cypress, Epson, Freescale, IDT, Lantiq, LSI, Maxim Integrated Products, Microchip, NXP Semiconductors, Renesas, Sony Semiconductor, ST-Ericsson, STMicroelectronics, Texas Instruments, Vectron International, Zarlink Semiconductor and others. We expect to face competition in the future from our current competitors, other manufacturers and designers of semiconductors, and start-up semiconductor design companies. As the markets for communications products grow, we also may face competition from traditional communications device companies. These companies may enter the mixed-signal semiconductor market by introducing their own ICs or by entering into strategic relationships with or acquiring other existing providers of semiconductor products. In addition, large companies may restructure their operations to create separate companies or may acquire new businesses that are focused on providing the types of products we produce or acquire our customers.
Our products must conform to industry standards and technology in order to be accepted by end users in our markets
Generally, our products comprise only a part of a device. All components of such devices must uniformly comply with industry standards in order to operate efficiently together. We depend on companies that provide other components of the devices to support prevailing industry standards. Many of these companies are significantly larger and more influential in affecting industry standards than we are. Some industry standards may not be widely adopted or implemented uniformly, and competing standards may emerge that may be preferred by our customers or end users. If larger companies do not support the same industry standards that we do, or if competing standards emerge, market acceptance of our products could be adversely affected which would harm our business.
Products for certain applications are based on industry standards that are continually evolving. Our ability to compete in the future will depend on our ability to identify and ensure compliance with these evolving industry standards. The emergence of new industry standards could render our products incompatible with products developed by other suppliers. As a result, we could be required to invest significant time and effort and to incur significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards for a significant period of time, we could miss opportunities to achieve crucial design wins.
Our pursuit of necessary technological advances may require substantial time and expense. We may not be successful in developing or using new technologies or in developing new products or product enhancements that achieve market acceptance. If our ICs fail to achieve market acceptance, our growth prospects, operating results and competitive position could be adversely affected.
Our primary facilities, housing engineering, sales and marketing, administration and test operations, are located in Austin, Texas. Our Austin, Texas operations currently occupy approximately 190,000 square feet of leased floor space with lease terms expiring at various dates through 2013. In addition to these properties, we lease smaller facilities in various locations in the United States, China, France, Germany, Hungary, Japan, Portugal, South Korea, Singapore, Taiwan and the United Kingdom for engineering, sales and marketing, administrative and manufacturing support activities. We believe that these facilities are suitable and adequate to meet our current operating needs.
On December 6, 2001, a class action complaint for violations of U.S. federal securities laws was filed in the United States District Court for the Southern District of New York against us, four of our officers individually and the three investment banking firms who served as representatives of the underwriters in connection with our initial public offering of common stock. The Consolidated Amended Complaint alleges that the registration statement and prospectus for our initial public offering did not disclose that (1) the underwriters solicited and received additional, excessive and undisclosed commissions from certain investors, and (2) the underwriters had agreed to allocate shares of the offering in exchange for a commitment from the customers to purchase additional shares in the aftermarket at pre-determined higher prices. The Complaint alleges violations of the Securities Act of 1933 and the Securities Exchange Act of 1934. The action seeks damages in an unspecified amount and is being coordinated with approximately 300 other nearly identical actions filed against other
companies. A court order dated October 9, 2002 dismissed without prejudice our four officers who had been named individually. On December 5, 2006, the Second Circuit vacated a decision by the District Court granting class certification in six of the coordinated cases, which are intended to serve as test, or "focus" cases. The plaintiffs selected these six cases, which do not include us. On April 6, 2007, the Second Circuit denied a petition for rehearing filed by the plaintiffs, but noted that the plaintiffs could ask the District Court to certify more narrow classes than those that were rejected.
The parties in the approximately 300 coordinated cases, including the parties in the case against us, reached a settlement. The insurers for the issuer defendants in the coordinated cases will make the settlement payment on behalf of the issuers, including us. On October 5, 2009, the Court granted final approval of the settlement. Six notices of appeal have been filed. Judgment was entered on January 13, 2010. The time to file additional notices of appeal is set to expire on February 12, 2010. A group of three objectors, who filed a notice of appeal, also filed a petition to the Second Circuit seeking permission to appeal the District Court's final approval of the settlement on the basis that the settlement class is broader than the class previously rejected by the Second Circuit in its December 5, 2006 order vacating the District Court's order certifying classes in the focus cases.
As the litigation process is inherently uncertain, we are unable to predict the outcome of the above described matter if the settlement does not survive the appeal. While we do maintain liability insurance, we could incur losses that are not covered by our liability insurance or that exceed the limits of our liability insurance. Such losses could have a material impact on our business and our results of operations or financial position.
We are involved in various other legal proceedings that have arisen in the normal course of business. While the ultimate results of these matters cannot be predicted with certainty, we do not expect them to have a material adverse effect on our consolidated financial position or results of operations.

Please read this selected consolidated financial data in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations," our Consolidated Financial Statements and the notes to those statements included in this Form 10-K. Financial data for fiscal years 2005 through 2006 has been reclassified to reflect the sale of our former Aero product lines as discontinued operations. The sale of these product lines closed in March 2007. See Note 3, Discontinued Operation, to the Consolidated Financial Statements for additional information.
The following discussion and analysis of financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements and related notes thereto included elsewhere in this report. This discussion contains forward-looking statements. Please see the "Cautionary Statement" and "Risk Factors" above for discussions of the uncertainties, risks and assumptions associated with these statements. Our fiscal year-end financial reporting periods are a 52- or 53- week year ending on the Saturday closest to December 31st. Fiscal year 2009 had 52 weeks and ended on January 2, 2010. Fiscal year 2008 had 53 weeks with the extra week occurring in the first quarter of the year and ended on January 3, 2009. Fiscal year 2007 had 52 weeks and ended December 29, 2007. Except as noted, financial results are for continuing operations. Our former Aero product lines are reported as discontinued operations. The sale of these product lines closed in March 2007.
We design and develop proprietary, analog-intensive, mixed-signal integrated circuits (ICs) for a broad range of applications. Mixed-signal ICs are electronic components that convert real-world analog signals, such as sound and radio waves, into digital signals that electronic products can process. Therefore, mixed-signal ICs are critical components in a broad range of applications in a variety of markets, including communications, consumer, industrial, automotive, medical and power management. Our major customers include 2Wire, Apple, Huawei, LG Electronics, Nokia, Philips, Samsung, Sony Ericsson, Thomson and Varian Medical Systems.
As a "fabless" semiconductor company, we rely on third-party semiconductor fabricators in Asia, and to a lesser extent the United States and Europe, to manufacture the silicon wafers that reflect our IC designs. Each wafer contains numerous die, which are cut from the wafer to create a chip for an IC. We rely on third-parties in Asia to assemble, package, and, in most cases, test these devices and ship these units to our customers. Testing performed by such third parties facilitates faster delivery of products to our customers (particularly those located in Asia), shorter production cycle times, lower inventory requirements, lower costs and increased flexibility of test capacity.
Our expertise in analog-intensive, high-performance, mixed-signal ICs enables us to develop highly differentiated solutions that address multiple markets. We group our products into the following categories:
Through acquisitions and internal development efforts, we have continued to diversify our product portfolio and introduce next generation ICs with added functionality and further integration. In fiscal 2009, we introduced a family of ultra-efficient microcontrollers for power-sensitive and battery-powered embedded systems, a family of highly integrated, energy-efficient quad Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controllers, a new line of automotive-qualified microcontrollers that
enable a dramatic reduction in system cost and footprint in body electronics applications, our QuickSense portfolio of highly accurate and fast-response touch, proximity and ambient light sensing devices, the expansion of our Any-Rate Precision Clock family with both a low jitter clock generator for broadcast video applications and web-customizable CMOS clock generators, a silicon hybrid TV tuner that supports both analog and digital broadcasts in a single device, a family of ProSLIC single channel telephony ICs for broadband networking equipment, the expansion of our small form factor microcontrollers in a tiny 2x2 mm footprint, a family of ISOpro high-performance, digital isolators, a family of high pin-count capacitive touch-sense microcontrollers for cost-sensitive embedded systems and the EZRadioPRO® embedded wireless radio family. We plan to continue to introduce products that increase the content we provide for existing applications, thereby enabling us to serve markets we do not currently address and expanding our total available market opportunity.
During fiscal 2009, we had one customer, Samsung, whose purchases across a variety of product areas represented 16% of our total revenues. We had no customers that accounted for more than 10% of our revenues during fiscal 2008 or 2007. In addition to direct sales to customers, some of our end customers purchase products indirectly from us through distributors and contract manufacturers. An end customer purchasing through a contract manufacturer typically instructs such contract manufacturer to obtain our products and incorporate such products with other components for sale by such contract manufacturer to the end customer. Although we actually sell the products to, and are paid by, the distributors and contract manufacturers, we refer to such end customer as our customer. Two of our distributors, Edom Technology and Avnet, represented 27% and 10% of our revenues during fiscal 2009, respectively. Edom represented 31% of our revenues during fiscal 2008. Edom and Avnet represented 36% and 10% of our revenues during fiscal 2007, respectively. There were no other distributors or contract manufacturers that accounted for more than 10% of our revenues in fiscal 2009, 2008 or 2007.
The percentage of our revenues derived from customers located outside of the United States was 88% in fiscal 2009 and 2008 and 87% in fiscal 2007. All of our revenues to date have been denominated in U.S. dollars. We believe that a majority of our revenues will continue to be derived from customers outside of the United States.
The sales cycle for our ICs can be as long as 12 months or more. An additional three to six months or more are usually required before a customer ships a significant volume of devices that incorporate our ICs. Due to this lengthy sales cycle, we typically experience a significant delay between incurring research and development and selling, general and administrative expenses, and the corresponding sales. Consequently, if sales in any quarter do not occur when expected, expenses and inventory levels could be disproportionately high, and our operating results for that quarter and, potentially, future quarters would be adversely affected. Moreover, the amount of time between initial research and development and commercialization of a product, if ever, can be substantially longer than the sales cycle for the product. Accordingly, if we incur substantial research and development costs without developing a commercially successful product, our operating results, as well as our growth prospects, could be adversely affected.
Because many of our ICs are designed for use in consumer products such as televisions, personal video recorders, set-top boxes, portable navigation devices and mobile handsets, we expect that the demand for our products will be typically subject to some degree of seasonal demand. However, rapid changes in our markets and across our product areas make it difficult for us to accurately estimate the impact of seasonal factors on our business.
In March 2007, we sold our Aero transceiver, AeroFONE single-chip phone and power amplifier product lines to NXP for $285 million in cash, plus additional earn-out potential of up to an aggregate
of $65 million over the following three years. The results of operations of the sold product lines have been presented as discontinued operations.
Results of Operations
The following describes the line items set forth in our Consolidated Statements of Income:
Revenues. Revenues are generated almost exclusively by sales of our ICs. We recognize revenue on sales when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable, and 4) collectibility is reasonably assured. Generally, we recognize revenue from product sales to direct customers and contract manufacturers upon shipment. Certain of our sales are made to distributors under agreements allowing certain rights of return and price protection on products unsold by distributors. Accordingly, we defer the revenue and cost of revenue on such sales until the distributors sell the product to the end customer. Our products typically carry a one-year replacement warranty. Replacements have been insignificant to date. Our revenues are subject to variation from period to period due to the volume of shipments made within a period, the mix of products we sell and the prices we charge for our products. The vast majority of our revenues were negotiated at prices that reflect a discount from the list prices for our products. These discounts are made for a variety of reasons, including: 1) to establish a relationship with a new customer, 2) as an incentive for customers to purchase products in larger volumes, 3) to provide profit margin to our distributors who resell our products or 4) in response to competition. In addition, as a product matures, we expect that the average selling price for such product will decline due to the greater availability of competing products. Our ability to increase revenues in the future is dependent on increased demand for our established products and our ability to ship larger volumes of those products in response to such demand, as well as our ability to develop or acquire new products and subsequently achieve customer acceptance of newly introduced products.
Cost of Revenues. Cost of revenues includes the cost of purchasing finished silicon wafers processed by independent foundries; costs associated with assembly, test and shipping of those products; costs of personnel and equipment associated with manufacturing support, logistics and quality assurance; costs of software royalties and amortization of purchased software, other intellectual property license costs and certain acquired intangible assets; an allocated portion of our occupancy costs; and allocable depreciation of testing equipment and leasehold improvements.
Research and Development. Research and development expense consists primarily of personnel-related expenses, including stock compensation, new product mask, wafer, packaging and test costs, external consulting and services costs, equipment tooling, equipment depreciation, amortization of acquired intangible assets, as well as an allocated portion of our occupancy costs for such operations. Research and development activities include the design of new products, refinement of existing products and design of test methodologies to ensure compliance with required specifications.
Selling, General and Administrative. Selling, general and administrative expense consists primarily of personnel-related expenses, including stock compensation, related allocable portion of our occupancy costs, sales commissions to independent sales representatives, applications engineering support, professional fees, patent litigation legal fees, costs related to relocating our headquarters and promotional and marketing expenses.
In-Process Research and Development. In-process research and development (IPR&D) represents acquired technology resulting from business combinations that had not achieved technological feasibility as of the acquisition closing date and had no alternative future use. For acquisitions occurring prior to fiscal 2009, these costs were expensed on the date of acquisition. Beginning in fiscal 2009, IPR&D acquired in business combinations is recorded as an indefinite-lived
intangible asset at fair value. The asset is tested for impairment through its completion and then amortized over its useful life.
Interest Income. Interest income reflects interest earned on our cash, cash equivalents and investment balances.
Interest Expense. Interest expense consists of interest on our short and long-term obligations.
Other Income (Expense), Net. Other income (expense), net reflects foreign currency remeasurement adjustments and gains and losses on the disposal of fixed assets.
Provision (Benefit) for Income Taxes. Provision (benefit) for income taxes includes both domestic and foreign income taxes at the applicable statutory rates adjusted for non-deductible expenses (including a portion of our stock compensation), research and development tax credits, interest income from tax-exempt investments and interest and penalties related to unrecognized tax benefits.
The following table sets forth our Consolidated Statements of Income data as a percentage of revenues for the periods indicated:
Comparison of Fiscal 2009 to Fiscal 2008
The growth in revenue in fiscal 2009 was driven primarily by market share gains. Increased unit volumes outpaced declines in average selling prices. Unit volumes of our products increased compared to fiscal 2008 by 19.6%. Average selling prices decreased during the same period by 10.8%. In general, as our products become more mature, we expect to experience decreases in average selling prices. We anticipate that newly announced, higher priced, next generation products and product derivatives will offset these decreases to some degree.
The increase in the dollar amount of gross margin in fiscal 2009 was primarily due to our increased sales. The increase in gross margin as a percent of revenue in fiscal 2009 was primarily due to a charge of $2.2 million to record inventory acquired from Integration Associates at fair value during fiscal 2008, improvements in our inventory management and manufacturing cost reductions. We may continue to experience declines in the average selling prices of certain of our products. This downward pressure on gross margin as a percentage of revenues may be offset to the extent we are able to: 1) introduce higher margin new products and gain market share with our ICs; 2) achieve lower production costs from our wafer suppliers and third-party assembly and test subcontractors; 3) achieve lower production costs per unit as a result of improved yields throughout the manufacturing process; or 4) reduce logistics costs.
Research and Development
The increase in research and development expense in fiscal 2009 was principally due to an increase of $3.7 million for personnel-related expenses, including personnel costs associated with the acquisition of Integration Associates. The decrease in research and development expense as a percent of revenues is due to our increased sales. For fiscal 2010, we expect that research and development expense will increase in absolute dollars, but remain relatively stable as a percentage of sales.
Significant recent development projects include a family of ultra-efficient microcontrollers for power-sensitive and battery-powered embedded systems, a family of highly integrated, energy-efficient quad PoE PSE controllers, a new line of automotive-qualified microcontrollers that enable a dramatic reduction in system cost and footprint in body electronics applications, our QuickSense portfolio of highly accurate and fast-response touch, proximity and ambient light sensing devices, the expansion of our Any-Rate Precision Clock family with both a low jitter clock generator for broadcast video applications and web-customizable 8-output CMOS clock generators, a silicon hybrid TV tuner that supports both analog and digital broadcasts in a single device, a family of ProSLIC single channel telephony ICs for broadband networking equipment, the expansion of our small form factor microcontrollers in a tiny 2x2 mm footprint, a family of ISOpro high-performance, digital isolators, a family of high pin-count capacitive touch-sense microcontrollers for cost-sensitive embedded systems and the EZRadioPRO embedded wireless radio family.
Selling, General and Administrative
The increase in selling, general and administrative expense in fiscal 2008 was principally due to an increase of $8.7 million for personnel-related expenses, including personnel costs associated with the acquisition of Integration Associates. For fiscal 2010, we expect that selling, general and administrative expense will increase in absolute dollars and decline slightly as a percentage of sales.
In-Process Research and Development
In-process research and development (IPR&D) recorded in connection with the acquisition of Integration Associates was $10.3 million in fiscal 2008. The IPR&D projects included optoelectronic, power, and radio transmitter and transceiver technologies. The optoelectronic projects are used for infrared data communications and proximity sensing. The power projects enable AC-DC conversion in power supply systems. The radio transmitters and transceivers projects enable the delivery of data over proprietary, short range wireless links. The fair value of each project was determined using the income approach. The discount rate applicable to the cash flows was 20%. This rate reflects the weighted-average cost of capital and the risks inherent in the development process.
There was no acquisition of IPR&D in fiscal 2009.
The decrease in interest income for the recent period was due to lower interest rates on the underlying instruments and lower average cash and investment balances.
Interest expense in fiscal 2009 was $0.2 million compared to $0.4 million in fiscal 2008.
Other Income (Expense), Net
Other income (expense), net in fiscal 2009 was $(0.1) million compared to $(0.6) million in fiscal 2008.
Provision (Benefit) for Income Taxes
The effective tax rate for fiscal 2009 decreased from the prior period, primarily due to resolution of uncertain tax positions as a result of us entering into an Advance Pricing Agreement with the U.S.
Internal Revenue Service during the fourth quarter of fiscal 2009. In addition, the effective tax rate for fiscal 2009 decreased from the prior period due to the intercompany license of certain technology and the non-deductible write-off of in-process research and development costs during fiscal 2008, both of which were related to the acquisition of Integration Associates. See Note 16, Income Taxes, to the Consolidated Financial Statements for additional information.
The effective tax rates for each of the periods presented differ from the federal statutory rate of 35% due to the amount of income earned in foreign jurisdictions where the tax rate may be lower than the federal statutory rate, the limited deductibility of stock compensation expense and other permanent items including changes to the liability for unrecognized tax benefits.
Comparison of Fiscal 2008 to Fiscal 2007
The growth in the sales of our products in fiscal 2008 was driven primarily by increased revenues from all of our product groups. Unit volumes of our products increased compared to fiscal 2007 by 50.8%. Average selling prices decreased during the same period by 19.4%. Unit volumes and average selling prices were substantially affected by the addition of certain high volume, low average selling price products through the Integration Associates acquisition. Excluding the Integration Associates products, during the same period, unit volumes increased by 28.1% and average selling prices decreased by only 8.1%.
The increase in the dollar amount of gross margin in fiscal 2008 was primarily due to our increased sales.
Research and Development
The increase in research and development expense in fiscal 2008 was principally due to (a) an increase of $8.6 million for personnel-related expenses, (b) $2.7 million of reduced occupancy and IT support costs during fiscal 2007, which were billed to NXP in connection with our transition services agreement (TSA) which has now expired, and (c) an increase of $1.8 million for product introduction costs. These impacts were partially offset by increased foreign research credits and incentives of $1.2 million in fiscal 2008. The decrease in research and development expense as a percent of revenues was due to our increased sales.
Selling, General and Administrative
The increase in selling, general and administrative expense in fiscal 2008 was principally due to (a) an increase of $6.4 million for personnel-related expenses, (b) $1.0 million of reduced occupancy costs during fiscal 2007 which were billed to NXP in connection with our TSA, and (c) an increase of $0.7 million for sales commissions. These impacts were partially offset by decreased legal fees, primarily related to litigation, of $2.6 million. The decrease in selling, general and administrative expense as a percent of revenues was due to our increased sales.
In-Process Research and Development
In-process research and development (IPR&D) recorded in connection with the acquisition of Integration Associates was $10.3 million in fiscal 2008. There was no acquisition of IPR&D in fiscal 2007.
The decrease in interest income for fiscal 2008 was due to lower interest rates on the underlying instruments and lower average cash and investment balances.
Interest expense in fiscal 2008 was $0.4 million compared to $0.6 million in fiscal 2007.
Other Income (Expense), Net
Other income (expense), net in fiscal 2008 was $(0.6) million compared to $(0.5) million in fiscal 2007.
Provision (Benefit) for Income Taxes
The effective tax rate for fiscal 2008 was higher than fiscal 2007 primarily due to a one-time tax cost associated with the intercompany licensing of certain intellectual property, the unfavorable impact of a reduction in tax exempt interest income and the non-deductible write-off of in-process research and development costs. These increases were partially offset by an increase in the foreign tax rate benefit and the reduction of the liability for unrecognized tax benefits due to the closure of an open tax year.
The effective tax rates for each of the periods presented differ from the federal statutory rate of 35% due to the amount of income earned in foreign jurisdictions where the tax rate may be lower than the federal statutory rate, tax exempt interest income, the limited deductibility of stock compensation expense and other permanent items including reductions of the liability for unrecognized tax benefits and non-deductible in-process research and development.
Income from Discontinued Operations, Net of Income Taxes
Revenues from our discontinued operations in fiscal 2008 were zero, as compared to $46.3 million in fiscal 2007. Income from our discontinued operations in fiscal 2007 included a gain on the sale of our Aero product lines of $224.9 million and a provision for income taxes of $62.2 million. We do not expect to recognize any additional revenue from our discontinued operations. See Note 3, Discontinued Operation, to the Consolidated Financial Statements for additional information.
We expect revenues in the first quarter of fiscal 2010 to be in the range of $120 to $125 million. Furthermore, we expect our diluted earnings per share to be in the range of $0.33 to $0.38.
Liquidity and Capital Resources
Our principal sources of liquidity as of January 2, 2010 consisted of $410.2 million in cash, cash equivalents and short-term investments. Our short-term investments consist primarily of U.S. government agency bonds and discount notes, corporate bonds, municipal bonds, U.S. Treasury bills, commercial paper, international government bonds and auction-rate securities purchased through UBS ("UBS auction-rate securities").
Our long-term investments consist of non-UBS auction-rate securities. Early in fiscal 2008, auctions for many of our auction-rate securities failed because sell orders exceeded buy orders. As of January 2, 2010, we held $51.3 million par value auction-rate securities, all of which have experienced failed auctions. The securities had previously been valued using quoted prices in active markets. When the auctions began to fail, quoted prices for the securities were no longer observable. As such, we changed our fair value measurement methodology for all auction-rate securities from quoted prices in active markets to a cash flow model. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, amount of cash flows, expected holding periods of the securities and a discount to reflect our inability to liquidate the securities.
The underlying assets of our auction-rate securities consisted of student loans and municipal bonds, of which $47.3 million were guaranteed by the U.S. government and the remaining $4.0 million were privately insured. As of January 2, 2010, $40.3 million of the auction-rate securities had credit ratings of AAA, $4.0 million had credit ratings of AA and $7.0 million had a credit rating of BBB. These securities had contractual maturity dates ranging from 2025 to 2046 and were yielding 0.46% to 2.79% per year at January 2, 2010. We are receiving the underlying cash flows on all of our auction-rate securities. The principal amounts associated with failed auctions are not expected to be accessible until a successful auction occurs, the issuer redeems the security, a buyer is found outside of the auction process or the underlying securities mature. We are unable to predict if these funds will become available before their maturity dates.
In November 2008, we entered into an agreement with UBS AG, which provides us certain rights to sell to UBS the auction-rate securities which were purchased through them. As of January 2, 2010, we held $24.0 million par value auction-rate securities purchased from UBS. We have the option to sell these securities to UBS at par value from June 30, 2010 through July 2, 2012. UBS, at its discretion, may purchase or sell these securities on our behalf at any time provided we receive par value for the securities sold. The issuers of the auction-rate securities continue to have the right to redeem the securities at their discretion. The agreement allows for the continuation of the accrual and payment of interest due on the securities. The agreement also provides us with access to loans of up to 75% of the market value of the unredeemed securities until June 30, 2010. These loans would carry interest rates which would be consistent with the interest income on the related auction-rate securities. As of January 2, 2010, we had no loans outstanding under this agreement.
We do not expect to need access to the capital represented by any of our auction-rate securities prior to their maturities. We do not intend to sell, and we believe that it is not more likely than not that we will be required to sell, our non-UBS investments before their anticipated recovery in market value or final settlement at the underlying par value. See Note 5, Cash, Cash Equivalents and Investments, to the Consolidated Financial Statements for additional information.
Net cash provided by operating activities was $120.9 million during fiscal 2009, compared to net cash provided of $119.7 million during fiscal 2008. Operating cash flows during fiscal 2009 reflect our net income of $73.1 million, adjustments of $66.2 million for depreciation, amortization, deferred income taxes and stock compensation, and a net cash outflow of $18.4 million due to changes in our operating assets and liabilities.
Accounts receivable increased to $56.1 million at January 2, 2010 from $36.1 million at January 3, 2009. The increase in accounts receivable resulted primarily from an increase in revenues during the three months ended January 2, 2010 compared to the three months ended January 3, 2009. Our average days sales outstanding (DSO) increased to 40 days at January 2, 2010 from 33 days at January 3, 2009.
Inventory increased to $31.5 million at January 2, 2010 from $28.3 million at January 3, 2009. Our inventory level is primarily impacted by our need to make purchase commitments to support forecasted demand and variations between forecasted and actual demand. Our average days of inventory (DOI) was 65 days at January 2, 2010 and January 3, 2009.
Net cash used in investing activities was $104.3 million during fiscal 2009, compared to net cash provided of $69.2 million during fiscal 2008. The decrease was principally due to an increase of $238.2 million in net outflows for purchases of investments and the receipt of $14.3 million previously held in escrow in connection with the sale of the Aero product lines during fiscal 2008, offset by a payment of $78.5 million for the acquisition of Integration Associates during fiscal 2008.
We anticipate capital expenditures of approximately $12 to $16 million for fiscal 2010. Additionally, as part of our growth strategy, we expect to evaluate opportunities to invest in or acquire other businesses, intellectual property or technologies that would complement or expand our current offerings, expand the breadth of our markets or enhance our technical capabilities.
Net cash provided by financing activities was $6.9 million during fiscal 2009, compared to net cash used of $281.0 million during fiscal 2008. The increase was principally due to a decrease of $266.0 million for repurchases of our common stock and an increase of $20.9 million from proceeds from the issuance of common stock. In October 2009, our Board of Directors authorized a program to repurchase up to $150 million of our common stock prior to the end of 2010.
The following table summarizes our contractual obligations as of January 2, 2010 (in thousands):
Our future capital requirements will depend on many factors, including the rate of sales growth, market acceptance of our products, the timing and extent of research and development projects, potential acquisitions of companies or technologies and the expansion of our sales and marketing activities. We believe our existing cash and investment balances are sufficient to meet our capital requirements through at least the next 12 months, although we could be required, or could elect, to seek additional funding prior to that time. We may enter into acquisitions or strategic arrangements in the future which also could require us to seek additional equity or debt financing.
Off-Balance Sheet Arrangements
In March 2006, we entered into an operating lease agreement and a related participation agreement for a facility at 400 W. Cesar Chavez ("400 WCC") in Austin, Texas for our corporate headquarters. The lease has a term of seven years. The base rent for the term of the lease is an amount equal to the interest accruing on $44.3 million at 110 basis points over the three-month LIBOR (which would be approximately $1.9 million over the remaining term assuming LIBOR averages 0.25% during such term).
In March 2008, we entered into an operating lease agreement and a related participation agreement for a facility at 200 W. Cesar Chavez ("200 WCC") in Austin, Texas for the expansion of our corporate headquarters. The lease has a term of five years. The base rent for the term of the lease is an amount equal to the interest accruing on $50.1 million at 155 basis points over the three-month LIBOR (which would be approximately $2.9 million over the remaining term assuming LIBOR averages 0.25% during such term).
We have granted certain rights and remedies to the lessors in the event of certain defaults, including the right to terminate the leases, to bring suit to collect damages, and to compel us to purchase the facilities. The leases contain other customary representations, warranties, obligations, conditions, indemnification provisions and termination provisions, including covenants that we shall maintain unencumbered cash and highly-rated short-term investments of at least $75 million. If our unencumbered cash and highly-rated short-term investments are less than $150 million, we must also maintain a ratio of funded debt to earnings before interest expense, income taxes, depreciation, amortization, lease expense and other non-cash charges (EBITDAR) over the four prior fiscal quarters
of no greater than 2 to 1. As of January 2, 2010, we believe we were in compliance with all covenants of the leases.
During the terms of the leases, we have on-going options to purchase the buildings for purchase prices of approximately $44.3 million for 400 WCC and $50.1 million for 200 WCC. Alternatively, we can cause each such property to be sold to third parties provided we are not in default under that property's lease. We are contingently liable on a first dollar loss basis for up to $35.3 million to the extent that the 400 WCC sale proceeds are less than the $44.3 million purchase option and up to $40.0 million to the extent that the 200 WCC sale proceeds are less than the $50.1 million purchase option.
We determined that the fair value associated with the guaranteed residual values was $1.0 million for 400 WCC and $1.2 million for 200 WCC, as of the inception of the leases. These amounts were recorded in "Other assets, net" and "Long-term obligations and other liabilities" in the Consolidated Balance Sheets and are being amortized over the term of the leases.
We are required to periodically evaluate the expected fair value of each facility at the end of the lease terms. If we determine that it is estimable and probable that the expected fair values will be less than $44.3 million for 400 WCC and $50.1 million for 200 WCC, we will ratably accrue the loss up to a maximum of approximately $35.3 million and $40.0 million, respectively, over the remaining lease terms as additional rent expense. As of January 2, 2010, we do not believe that a loss contingency accrual is required for either property. However, a prolonged economic downturn could increase the likelihood of such a loss accrual.
In connection with our headquarters leases, during fiscal 2008 we entered into interest rate swap agreements as a hedge against the variable rent under the leases. Under the terms of the swap agreements, we have effectively converted the variable rents to fixed rents through March 2011 for 400 WCC and March 2013 for 200 WCC. See Note 6, Derivative Financial Instruments, to the Consolidated Financial Statements for additional information.
Critical Accounting Policies and Estimates
The preparation of financial statements and accompanying notes in conformity with U.S. generally accepted accounting principles requires that we make estimates and assumptions that affect the amounts reported. Changes in facts and circumstances could have a significant impact on the resulting estimated amounts included in the financial statements. We believe the following critical accounting policies affect our more complex judgments and estimates. We also have other policies that we consider to be key accounting policies, such as our policies for revenue recognition, including the deferral of revenues and cost of revenues on sales to distributors; however, these policies do not meet the definition of critical accounting estimates because they do not generally require us to make estimates or judgments that are difficult or subjective.
Inventory valuationWe assess the recoverability of inventories through the application of a set of methods, assumptions and estimates. In determining net realizable value, we write down inventory that may be slow moving or have some form of obsolescence, including inventory that has aged more than 12 months. We also adjust the valuation of inventory when its standard cost exceeds the estimated market value. We assess the potential for any unusual customer returns based on known quality or business issues and write-off inventory losses for scrap or non-saleable material. Inventory not otherwise identified to be written down is compared to an assessment of our 12-month forecasted demand. The result of this methodology is compared against the product life cycle and competitive situations in the marketplace to determine the appropriateness of the resulting inventory levels. Demand for our products may fluctuate significantly over time, and actual demand and market conditions may be more or less favorable than those that we project. In the event that actual demand is
lower or market conditions are worse than originally projected, additional inventory write-downs may be required.
Stock compensationWe recognize the fair-value of stock-based compensation transactions in the Consolidated Statement of Income. The fair value of our stock-based awards is estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes valuation calculation requires us to estimate key assumptions such as future stock price volatility, expected terms, risk-free rates and dividend yield. Expected stock price volatility is based on implied volatility from traded options on our stock in the marketplace and historical volatility of our stock. The expected term of options granted is derived from an analysis of historical exercises and remaining contractual life of stock options, and represents the period of time that options granted are expected to be outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. We have never paid cash dividends, and do not currently intend to pay cash dividends, and thus have assumed a 0% dividend yield. In addition, we are required to estimate the expected forfeiture rate of our stock grants and only recognize the expense for those shares expected to vest. If our actual experience differs significantly from the assumptions used to compute our stock-based compensation cost, or if different assumptions had been used, we may have recorded too much or too little stock-based compensation cost. See Note 13, Stock-Based Compensation, to the Consolidated Financial Statements for additional information.
Investments in auction-rate securitiesWe determine the fair value of our investments in auction-rate securities using a discounted cash flow model. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, amount of cash flows, expected holding periods of the securities and a discount to reflect our inability to liquidate the securities. For available-for-sale auction-rate securities, if the calculated value is below the carrying amount of the securities, we then determine if the decline in value is other-than-temporary. We consider various factors in determining whether an impairment is other-than-temporary, including the severity and duration of the impairment, changes in underlying credit ratings, forecasted recovery, our intent to sell or the likelihood that we would be required to sell the investment before its anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. When we conclude that an other-than-temporary impairment has occurred, we assess whether we intend to sell the security or if it is more likely than not that we will be required to sell the security before recovery. If either of these two conditions is met, we recognize a charge in earnings equal to the entire difference between the security's amortized cost basis and its fair value. If we do not intend to sell a security or it is not more likely than not that we will be required to sell the security before recovery, the unrealized loss is separated into an amount representing the credit loss, which is recognized in earnings, and the amount related to all other factors, which is recorded in accumulated other comprehensive loss.
Impairment of goodwill and other long-lived assetsWe review long-lived assets which are held and used, including fixed assets and purchased intangible assets, for impairment whenever changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Such evaluations compare the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset over its expected useful life and are significantly impacted by estimates of future prices and volumes for our products, capital needs, economic trends and other factors which are inherently difficult to forecast. If the asset is considered to be impaired, we record an impairment charge equal to the amount by which the carrying value of the asset exceeds its fair value determined by either a quoted market price, if any, or a value determined by utilizing a discounted cash flow technique.
We test our goodwill for impairment annually as of the first day of our fourth fiscal quarter and in interim periods if certain events occur indicating that the carrying value of goodwill may be impaired.
The goodwill impairment test is a two-step process. The first step of the impairment analysis compares our fair value to our net book value. In determining fair value, the accounting guidance allows for the use of several valuation methodologies, although it states quoted market prices are the best evidence of fair value. If the fair value is less than the net book value, the second step of the analysis compares the implied fair value of our goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, we recognize an impairment loss equal to that excess amount.
Income taxesWe are required to estimate income taxes in each of the jurisdictions in which we operate. This process involves estimating the actual current tax liability together with assessing temporary differences in recognition of income (loss) for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our Consolidated Balance Sheet. We then assess the likelihood that the deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, we establish a valuation allowance against the deferred tax asset.
We recognize liabilities for uncertain tax positions based on a two-step process. The first step requires us to determine if the weight of available evidence indicates that the tax position has met the threshold for recognition; therefore, we must evaluate whether it is more likely than not that the position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step requires us to measure the tax benefit of the tax position taken, or expected to be taken, in an income tax return as the largest amount that is more than 50% likely of being realized upon ultimate settlement. This measurement step is inherently complex and requires subjective estimations of such amounts to determine the probability of various possible outcomes. We re-evaluate the uncertain tax positions each quarter based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, expirations of statutes of limitation, effectively settled issues under audit, and new audit activity. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision in the period.
Although we believe the measurement of our liabilities for uncertain tax positions is reasonable, no assurance can be given that the final outcome of these matters will not be different than what is reflected in the historical income tax provisions and accruals. If additional taxes are assessed as a result of an audit or litigation, it could have a material effect on our income tax provision and net income in the period or periods for which that determination is made. We operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues which may require an extended period of time to resolve and could result in additional assessments of income tax. We believe adequate provisions for income taxes have been made for all periods.
Recent Accounting Pronouncements
In April 2009, the FASB issued the following:
These ASCs are effective for reporting periods ending after June 15, 2009 and were adopted by us on April 5, 2009. The adoption of the ASCs did not have a material impact on our financial statements.

We adopted ASC 260-10-45 at the beginning of fiscal 2009. The adoption did not have a material impact on our financial statements.
Our investment portfolio includes cash, cash equivalents, short-term investments and long-term investments. Our main investment objectives are the preservation of investment capital and the maximization of after-tax returns on our investment portfolio. Our interest income is sensitive to changes in the general level of U.S. interest rates. Based on our investment portfolio holdings as of January 3, 2009, an immediate 100 basis point decline in the yield for such instruments would decrease our annual interest income by approximately $3.3 million. Our investment portfolio holdings as of January 2, 2010 yielded less than 100 basis points. A decline in yield to zero basis points on our investment portfolio holdings as of January 2, 2010 would decrease our annual interest income by approximately $2.6 million. We believe that our investment policy is conservative, both in the duration of our investments and the credit quality of the investments we hold.
Headquarters Lease Rent
We are exposed to interest rate fluctuations in the normal course of our business, including through our corporate headquarters leases. The base rents for these leases are calculated using a variable interest rate based on the three-month LIBOR. We have entered into interest rate swap agreements with notional values of $44.3 million and $50.1 million and, effectively, fixed the rent payment amounts on these leases through March 2011 and March 2013, respectively. The fair value of the interest rate swap agreements at January 2, 2010 was a $4.5 million obligation.
Investments in Auction-rate Securities
Beginning in fiscal 2008, auctions for many of our auction-rate securities failed because sell orders exceeded buy orders. As of January 2, 2010, we held $51.3 million par value auction-rate securities, all of which have experienced failed auctions. The principal amounts associated with failed auctions are not expected to be accessible until a successful auction occurs, the issuer redeems the securities, a buyer is found outside of the auction process or the underlying securities mature. We are unable to predict if these funds will become available before their maturity dates. Additionally, if we determine that an other-than-temporary decline in the fair value of any of our available-for-sale auction-rate securities has occurred, we may be required to adjust the carrying value of the investments through an impairment charge. In November 2008, we entered into an agreement with UBS, which provides us certain rights to sell to UBS the auction-rate securities which were purchased through them. As of January 2, 2010, we held $24.0 million par value auction-rate securities purchased from UBS. We have
the option to sell these securities to UBS at par value from June 30, 2010 through July 2, 2012. See Note 5, Cash, Cash Equivalents and Investments, to the Consolidated Financial Statements for additional information.
The Financial Statements and supplementary data required by this item are included in Part IV, Item 15 of this Form 10-K and are presented beginning on page F-1.
We have performed an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the Exchange Act). Based on that evaluation, our management, including our CEO and CFO, concluded that our disclosure controls and procedures were effective as of January 2, 2010 to provide reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Such disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed is accumulated and communicated to our management, including our CEO and CFO, to allow timely decisions regarding required disclosures. There was no change in our internal controls during the fiscal quarter ended January 2, 2010 that materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
Management's Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system was designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements.
Our management assessed the effectiveness of our internal control over financial reporting as of January 2, 2010. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal ControlIntegrated Framework. Based on our assessment we concluded that, as of January 2, 2010, our internal control over financial reporting is effective based on those criteria.
Our independent registered public accounting firm, Ernst & Young LLP, issued an attestation report on our internal control over financial reporting. This report appears on page F-1.
Certain information required by Part III is omitted from this report because we intend to file a definitive Proxy Statement pursuant to Regulation 14A (the "Proxy Statement") no later than 120 days after the end of the fiscal year covered by this report, and certain information to be included therein is incorporated herein by reference.

Pursuant to the requirements of the Securities Exchange Act of 1934, this report has been signed below by the following persons on behalf of the registrant and in the capacities and on the dates indicated:
The Board of Directors and Stockholders of Silicon Laboratories Inc.
We have audited Silicon Laboratories Inc.'s internal control over financial reporting as of January 2, 2010, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Silicon Laboratories Inc.'s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company's internal control over financial reporting is a process designed 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, Silicon Laboratories Inc. maintained, in all material respects, effective internal control over financial reporting as of January 2, 2010, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Silicon Laboratories Inc. as of January 2, 2010 and January 3, 2009, and the related consolidated statements of income, changes in stockholders' equity, and cash flows for each of the three fiscal years in the period ended January 2, 2010 of Silicon Laboratories Inc. and our report dated February 10, 2010 expressed an unqualified opinion thereon.
The Board of Directors and Stockholders of Silicon Laboratories Inc.
We have audited the accompanying consolidated balance sheets of Silicon Laboratories Inc. as of January 2, 2010 and January 3, 2009, and the related consolidated statements of income, changes in stockholders' equity, and cash flows for each of the three fiscal years in the period ended January 2, 2010. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Silicon Laboratories Inc. at January 2, 2010 and January 3, 2009, and the consolidated results of its operations and its cash flows for each of the three fiscal years in the period ended January 2, 2010, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Silicon Laboratories Inc.'s internal control over financial reporting as of January 2, 2010, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 10, 2010 expressed an unqualified opinion thereon.

1. Description of Business
Silicon Laboratories Inc. (the "Company"), a Delaware corporation, develops and markets mixed-signal analog intensive integrated circuits (ICs) for a broad range of applications for global markets. Within the semiconductor industry, the Company is known as a "fabless" company meaning that the ICs are manufactured by third-party foundry semiconductor companies.
In March 2007, the Company sold its Aero transceiver, AeroFONE single-chip phone and power amplifier product lines (the "Aero product lines") to NXP B.V. and NXP Semiconductors France SAS (collectively "NXP"). The financial results of the sold product lines have been presented as discontinued operations in the Consolidated Financial Statements. See Note 3, Discontinued Operation, for additional information.
2. Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
The Company prepares financial statements on a 52-53 week year that ends on the Saturday closest to December 31. Fiscal 2009 had 52 weeks and ended January 2, 2010. Fiscal 2008 had 53 weeks with the extra week occurring in the first quarter of the year and ended January 3, 2009. Fiscal year 2007 had 52 weeks and ended December 29, 2007. The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
Foreign Currency Transactions
The functional currency of the Company's foreign subsidiaries is the U.S. dollar; accordingly, all gains and losses resulting from remeasuring transactions denominated in currencies other than U.S. dollars are included in net income.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Among the significant estimates affecting the financial statements are those related to inventories, stock compensation, investments in auction-rate securities, goodwill, long-lived assets and income taxes. Actual results could differ from those estimates, and such differences could be material to the financial statements.
Certain reclassifications have been made to prior year financial statements to conform to current year presentation.
2. Significant Accounting Policies (Continued)
Fair Value of Financial Instruments
The fair values of the Company's financial instruments are recorded using a hierarchal disclosure framework based upon the level of subjectivity of the inputs used in measuring assets and liabilities. The three levels are described below:
Level 1Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.
Level 2Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3Inputs are unobservable for the asset or liability and are developed based on the best information available in the circumstances, which might include the Company's own data.
Cash and Cash Equivalents
Cash and cash equivalents consist of cash deposits, money market funds and investments in debt securities with original maturities of ninety days or less when purchased.
The Company's investments consist primarily of U.S. government agency bonds and discount notes, corporate bonds, municipal bonds, U.S. Treasury bills, commercial paper, international government bonds and auction-rate securities. These securities typically have original maturities greater than ninety days as of the date of purchase and are classified as available-for-sale or trading securities. Investments in available-for-sale securities are reported at fair value, with unrealized gains and losses, net of tax, recorded as a component of accumulated other comprehensive loss in the Consolidated Balance Sheet. Investments in trading securities are reported at fair value, with both realized and unrealized gains and losses recorded in other income (expense), net in the Consolidated Statement of Income. Investments in which the Company has the ability and intent, if necessary, to liquidate in order to support its current operations (including those with contractual maturities greater than one year from the date of purchase) are classified as short-term. The Company's long-term investments consist of auction-rate securities.
The Company reviews its available-for-sale investments as of the end of each reporting period for other-than-temporary declines in fair value based on the specific identification method. The Company considers various factors in determining whether an impairment is other-than-temporary, including the severity and duration of the impairment, changes in underlying credit ratings, forecasted recovery, its intent to sell or the likelihood that it would be required to sell the investment before its anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. When the Company concludes that an other-than-temporary impairment has occurred, the Company assesses whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before recovery. If either of these two conditions is met, the Company recognizes a charge in earnings equal to the entire difference between the security's amortized cost basis and its fair value. If the Company does not intend to sell a security or it is not more likely than not that it will be required to sell the security before recovery, the unrealized loss is separated into an
2. Significant Accounting Policies (Continued)
amount representing the credit loss, which is recognized in earnings, and the amount related to all other factors, which is recorded in accumulated other comprehensive loss.
Derivative Financial Instruments
The Company uses derivative financial instruments to manage exposures to the variability of interest rates used to calculate base rents for its corporate headquarters leases. The Company's objective is to offset increases and decreases in expenses resulting from changes in interest rates with losses and gains on the derivative contracts, thereby reducing volatility of earnings. The Company does not use derivative contracts for speculative purposes. The effective portion of the gain or loss on interest rate swaps is recorded in accumulated other comprehensive loss as a separate component of stockholders' equity and is subsequently recognized in earnings when the hedged exposure affects earnings. Cash flows from derivatives are classified as cash flows from operating activities in the Consolidated Statement of Cash Flows.
Inventories are stated at the lower of cost, determined using the first-in, first-out method, or market.
Property and Equipment
Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the useful lives of the assets ranging from three to five years. Leasehold improvements are depreciated over the contractual lease period or their useful life, whichever is shorter.
Purchased intangible assets are stated at cost, net of accumulated amortization, and are amortized using the straight-line method over their estimated useful lives, ranging from four to twelve years.
Long-lived assets "held and used" by the Company are reviewed for impairment whenever events or changes in circumstances indicate that their net book value may not be recoverable. When such factors and circumstances exist, the Company compares the projected undiscounted future cash flows associated with the related asset or group of assets over their estimated useful lives, against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets and is recorded in the period in which the determination was made.
The carrying value of goodwill is reviewed at least annually by the Company for possible impairment. The goodwill impairment test is a two-step process. The first step of the impairment analysis compares the fair value of the company or reporting unit to the net book value of the company or reporting unit. In determining fair value, several valuation methodologies are allowed, although quoted market prices are the best evidence of fair value. If the results of the first step demonstrate that the net book value is greater than the fair value, the Company must proceed to step two of the analysis. Step two of the analysis compares the implied fair value of goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, an impairment loss is recognized equal
2. Significant Accounting Policies (Continued)
to that excess. The Company tests goodwill for impairment annually as of the first day of its fourth fiscal quarter and in interim periods if events occur that would indicate that the carrying value of goodwill may be impaired.
Revenues are generated almost exclusively by sales of the Company's ICs. The Company recognizes revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable, and 4) collectibility is reasonably assured. Generally, revenue from product sales to direct customers and contract manufacturers is recognized upon shipment.
A portion of the Company's sales are made to distributors under agreements allowing certain rights of return and price protection related to the final selling price to the end customers. Accordingly, the Company defers revenue and cost of revenue on such sales until the distributors sell the product to the end customers. The net balance of deferred revenue less deferred cost of revenue associated with inventory shipped to a distributor but not yet sold to an end customer is recorded in the "deferred income on shipments to distributors" liability on the Consolidated Balance Sheet. Such net deferred income balance reflects the Company's estimate of the impact of rights of return and price protection.
Shipping and Handling
Shipping and handling costs are classified as a component of cost of revenues in the Consolidated Statements of Income.
The Company has stock-based compensation plans, which are more fully described in Note 13, Stock-Based Compensation. The Company accounts for those plans using a fair-value method and recognizes the expense in its Consolidated Statement of Income.
Advertising costs are expensed as incurred. Advertising expenses were $1.5 million, $1.7 million and $1.1 million and in fiscal 2009, 2008 and 2007, respectively.
The Company accounts for income taxes using the asset and liability method whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax laws and related rates that will be in effect when the differences are expected to reverse. These differences result in deferred tax assets and liabilities, which are included in the Company's Consolidated Balance Sheet. The Company then assesses the likelihood that the deferred tax assets will be recovered from future taxable income. A valuation allowance is established against deferred tax assets to the extent the Company believes that recovery is not likely based on the level of historical taxable income and projections for future taxable income over the periods in which the temporary differences are deductible.
2. Significant Accounting Policies (Continued)
Uncertain tax positions must meet a more-likely-than-not threshold to be recognized in the financial statements and the tax benefits recognized are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon final settlement. See further discussion in Note 16, Income Taxes.
Recent Accounting Pronouncements
In April 2009, the Financial Accounting Standards Board (FASB) issued the following:
These ASCs are effective for reporting periods ending after June 15, 2009 and were adopted by the Company on April 5, 2009. The adoption of the ASCs did not have a material impact on the Company's financial statements.
In June 2008, the FASB issued FASB ASC 260-10-45, formerly FSP Emerging Issues Task Force (EITF) 03-6-1, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities. ASC 260-10-45 provides that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method described in FASB ASC 260, Earnings per Share. ASC 260-10-45 is effective for financial statements issued for fiscal years beginning after December 15, 2008 and interim periods within those years on a retrospective basis. The Company adopted ASC 260-10-45 at the beginning of fiscal 2009. The adoption did not have a material impact on the Company's financial statements.
3. Discontinued Operation
In March 2007, the Company sold its Aero product lines to NXP for $285 million in cash, plus additional earn-out potential of up to an aggregate of $65 million over the next three years. To date, no additional earn-out has been recognized from this transaction.
3. Discontinued Operation (Continued)
The financial results of the sold product lines have been presented as discontinued operations in the Consolidated Financial Statements. The following summarizes results from the discontinued operations (in thousands, except per share data):
During fiscal 2007, the Company made $45.0 million of estimated tax payments due primarily to the gain on the sale of its Aero product lines and received $26.2 million for the exercise of stock options from employees who were hired by NXP associated with the sale of the Aero products.
In connection with the closing of the sale, the Company entered into certain ancillary agreements with NXP, including a Transition Services Agreement ("TSA") and an Intellectual Property License Agreement ("IPLA"). Through the TSA, the Company subleased certain premises to NXP and provided various temporary support services, such as IT support services. Such services were provided for approximately six months from the closing date and are no longer being provided. The fees for these services were generally equivalent to the Company's cost and were approximately $3.9 million in fiscal 2007. Through the IPLA, the Company granted NXP a license with respect to retained intellectual property and NXP granted a license to the Company with respect to transferred intellectual property. However, these cross-license agreements do not involve the receipt or payment of any royalties and therefore are not considered to be a component of continuing involvement.
4. Earnings Per Share
The following table sets forth the computation of basic and diluted earnings per share from continuing operations (in thousands, except per share data):
Approximately 2.1 million, 4.2 million and 4.0 million weighted-average dilutive potential shares of common stock have been excluded from the diluted earnings per share calculation for fiscal years ended January 2, 2010, January 3, 2009 and December 29, 2007, respectively, as they were anti-dilutive.
5. Cash, Cash Equivalents and Investments
The Company's cash equivalents and short-term investments consist primarily of money market funds, U.S. government agency bonds and discount notes, corporate bonds, municipal bonds, U.S. Treasury bills, U.S. government bonds, commercial paper, international government bonds and auction-rate securities purchased through UBS ("UBS auction-rate securities"). The Company's long-term investments consist of non-UBS auction-rate securities. Early in fiscal 2008, auctions for many of the Company's auction-rate securities failed because sell orders exceeded buy orders. As of January 2, 2010, the Company held $51.3 million par value auction-rate securities, all of which have experienced failed auctions. The underlying assets of the securities consisted of student loans and municipal bonds, of which $47.3 million were guaranteed by the U.S. government and the remaining $4.0 million were privately insured. As of January 2, 2010, $40.3 million of the auction-rate securities had credit ratings of AAA, $4.0 million had credit ratings of AA and $7.0 million had a credit rating of BBB. These securities had contractual maturity dates ranging from 2025 to 2046 and with current yields of 0.46% to 2.79% per year at January 2, 2010. The Company is receiving the underlying cash flows on all of its auction-rate securities. The principal amounts associated with failed auctions are not expected to be accessible until a successful auction occurs, the issuer redeems the securities, a buyer is found outside of the auction process or the underlying securities mature. The Company is unable to predict if these funds will become available before their maturity dates.
5. Cash, Cash Equivalents and Investments (Continued)
In November 2008, the Company entered into an agreement with UBS AG, which provides the Company certain rights to sell to UBS the auction-rate securities which were purchased through them. As of January 2, 2010, the Company held $24.0 million par value auction-rate securities purchased from UBS. The Company has the option to sell these securities to UBS at par value from June 30, 2010 through July 2, 2012. UBS, at its discretion, may purchase or sell these securities on the Company's behalf at any time provided the Company receives par value for the securities sold. The issuers of the auction-rate securities continue to have the right to redeem the securities at their discretion. The agreement allows for the continuation of the accrual and payment of interest due on the securities. The agreement also provides the Company with access to loans of up to 75% of the market value of the unredeemed securities until June 30, 2010. These loans would carry interest rates which would be consistent with the interest income on the related auction-rate securities. As of January 2, 2010, the Company had no loans outstanding under this agreement.
The Company's right to sell the auction-rate securities to UBS commencing June 30, 2010 represents a put option for a payment equal to the par value of the auction-rate securities. As the put option is non-transferable and cannot be attached to the auction-rate securities if they are sold to another entity other than UBS, it represents a freestanding instrument between the Company and UBS. The Company elected to record the put option at fair value. During fiscal 2008, the Company recorded a gain of $5.0 million representing (a) the initial fair value of the put option, and (b) the changes in the fair value of the put option from November to the end of the year. The Company has classified the UBS auction-rate securities as trading securities and, accordingly, recognizes changes in fair value in earnings. During fiscal 2008, the Company recorded a loss of $5.1 million representing (a) the transfer of the UBS auction-rate securities from available-for-sale to trading securities and, accordingly, recognizing the unrealized losses previously recorded in accumulated other comprehensive loss in earnings at the election date, and (b) the subsequent changes in fair value from the election date to the end of the year. Both the gain from recording the put option at fair value and the loss due to the transfer from available-for-sale to trading securities, as well as subsequent fair value adjustments, were recorded in "other income (expense), net". Adjustments to the fair values of the put option and the trading securities generally offset each other. The Company intends to exercise its option to sell its UBS auction-rate securities to UBS on June 30, 2010 and has therefore classified both the UBS auction-rate securities and the related put option as short-term investments as of January 2, 2010.
The Company does not expect to need access to the capital represented by any of its auction-rate securities prior to their maturities. The Company does not intend to sell, and believes it is not more likely than not that it will be required to sell, its non-UBS auction-rate securities before their anticipated recovery in market value or final settlement at the underlying par value. The Company believes that the credit ratings and credit support of the security issuers indicate that they have the ability to settle the securities at par value. As such, the Company has determined that no material other-than-temporary impairment losses existed as of January 2, 2010.
