Background of the Semiconductor Industry
     In general, the semiconductor industry produces three types of products: analog, mixed-signal and digital. Analog semiconductors take on a continuous range of values that can regulate functions such as temperature, speed, sound, video images and electrical current. Mixed-signal semiconductors combine analog and digital functions in a single product. Digital semiconductors process discrete values, for example, two values, such as 0s and 1s, used by computers.
     In the consumer electronics industry, until recently, audio soundtracks and video images were transmitted, edited and stored almost exclusively using analog formats. Given advances in technology, audio and video now can be stored in digital format. This format allows for the manipulation of audio and video signals through digital signal processors (“DSPs”). With digital signal processors, digital audio and digital video signals can be compressed, improving storage and efficiencies in transmissions and they can be transmitted and reproduced without degradation in the sound or images. Digital formatting also provides greater security from unauthorized copying, better editing capabilities and random access to data.
     In addition, increasing advances in semiconductor technology are resulting in the convergence of consumer electronics products, which means cost savings and added convenience and functionality for consumers. For example, compact disk (“CD”) players were introduced to play audio content in the CD format only. Later, digital video disk (“DVD”) players were introduced, combining audio with video. These consumer electronics products now support additional audio and video formats, such as MP3 audio and MPEG-4 video. As these digital home entertainment systems converge and become increasingly complex, makers of these systems will need sophisticated IC chips that have many features and are cost-effective.
     Manufacturers of consumer electronics products also face expedited time-to-market demands. In addition, because analog or mixed-signal IC design is a specialized field of IC design, manufacturers increasingly are asking third parties to provide advanced, analog and/or mixed-signal ICs. The design of the analog component of a mixed-signal IC is complex and requires engineers to optimize speed, power and resolution within standard manufacturing processes.
Markets and Products
     We develop high-precision analog and mixed-signal ICs for a broad range of consumer and industrial markets. Building on our diverse analog mixed-signal patent portfolio, we deliver highly optimized products for consumer and commercial audio, automotive entertainment and industrial applications. During fiscal year 2005, we announced that we would be implementing a product-line structure focusing on the following four product lines:

     We offer advanced ICs combined with innovation in software solutions, providing customers features that differentiate their products against their competitors. As an example, in fiscal year 2005 we introduced Intelligent Room Calibration (IRC) software technology for the CS495XX and CS494XX audio DSPs. This software serves to differentiate Cirrus Logic audio DSPs by giving audio/video receiver (“AVR”) customers additional consumer features, such as: (1) speaker set-up for adjusting the timing of sounds to the ear from different speakers in a room and (2) room equalization, which optimizes the audio to accommodate room acoustics (e.g., tiled floors and heavy carpeting) that frequently distort audio frequencies. Our advanced audio DSP products are also used in many audio intensive applications including digital televisions, automotive audio and multi-media speakers.
     In the general purpose embedded processor segment, our ARM-based family of processors offers a highly-integrated 32-bit system-on-a-chip (“SoC”) solution with a wide array of price-performance-integration points for optimal design options. These embedded processors support such popular third-party operating system software as Linux and WinCE Net™.
     In networked digital audio applications, our CobraNet technology solution enables the delivery of uncompressed digital audio over Ethernet networks. The digital audio packets co-exist with standard Ethernet network data traffic. In fiscal year 2005, Cirrus Logic introduced its first ICs that feature CobraNet technology. Over 40 companies are building commercial and professional audio products that use our CobraNet technology for digital audio networking.
     New additions introduced to our embedded product ICs in the last fiscal year include:

 	•  	three new 32-bit ARM9-based (“the Nine-Series”) embedded processors for a wide variety of consumer, commercial and industrial applications.

     Our customers include Bose, Harman Pro companies, Kenwood, LG Electronics, Marantz, Onkyo, Panasonic, Pioneer, Ray Marine, RCA/Thomson S.A., Scientific Atlanta, Sony, the United States Senate, and Yamaha. Our competitors in embedded product solutions include Analog Devices, Freescale Semiconductor, Samsung and Texas Instruments/Burr Brown.
VIDEO
     We provide versatile silicon and software “platform” solutions for such markets as DVD recorders, home theater recorders and PC-based USB peripheral products. Our strategy of providing “platform” solutions is designed to help manufacturers get to market faster with cost-effective, proven ICs for encoding and processing of digital audio and video.
     In addition, we have also developed a modular software structure that provides a simplified, elegant user interface. To help eliminate consumer confusion over various DVD recording formats, we introduced software in the last fiscal year that supports recording and playback in both the “+” and “-” formats.
     New products include:

 	•  	the CS98300 DVD processor IC, which is fully certified to play back DivX Ô -technology-based content.	
 	
 	•  	the USB-DVR 3.0 reference design, which features the CS92688 MPEG encoder, the CS4245 audio codec or CS5345 analog-to-digital converters. This reference design allows the conversion of analog and digital video into MPEG-2 video for instant DVD burning. This reference design is featured in products that connect to PCs via USB cable;	
 	
 	•  	the Home Theater Recorder reference platform, which combines the features of a digital A/V receiver with a DVD recorder. This reference platform is based upon our DVD recorder platforms and features the new CS44600/800 family of multi-channel Class-D digital amplifier controllers.	
     Our customers, several of which sell products under their own brand name as well as other retail brands, for digital video encoding products include ADS Technologies, CyberHome, Ellion, Kiss, LG Electronics, Mustek, Pinnacle Systems, Samsung and Sony. These products primarily compete with products from LSI Logic and Zoran.
     On April 25, 2005, we announced our intentions to divest our video product line. On May 24, 2005, we signed a definitive agreement to sell our digital video product line to Magnum Semiconductor Inc., a privately held company formed by an investment group led by Investcorp and August Capital. By divesting the video product line, we intend to focus on our core analog, mixed-signal and embedded IC product lines for audio and industrial markets. With this focus, we expect to be poised to leverage our intellectual property and higher gross margin analog product lines to drive growth and sustainable profitability. The transaction is structured as an asset sale and is currently expected to close in approximately 45 to 75 days. As consideration for the sale of these assets, we will receive a minority equity ownership position in Magnum Semiconductor and is anticipating it will account for its ownership position under the cost method of accounting. Upon completion of the transaction, we expect to record a one-time charge of approximately $7 million, which consists primarily of $5 million in anticipated costs associated with the company’s exit from excess leased facilities and an estimated $1.5 million in expected professional fees associated with the transaction. The transaction is subject to certain closing conditions, including conditions requiring that certain approvals, consents and agreements be obtained.
Manufacturing
     We contract with third-parties for all of our wafer fabrication, assembly, and test services. Our fabless manufacturing strategy allows us to concentrate on our design strengths, minimize fixed costs and capital expenditures, access advanced manufacturing facilities and provides flexibility to source multiple leading-edge technologies through strategic alliances. After wafer fabrication by the foundry, third-party assembly vendors package the wafer die. The finished products are then sent for testing before shipment to our customers. Our supply chain management organization qualifies each product, participates in process and package development, defines and controls the manufacturing process at our suppliers, develops test programs and performs production testing of
Page 6 of 71

Table of Contents

products in accordance with our ISO-certified quality management system. We use multiple foundries, assembly and test houses.
     On June 26, 2003, we announced that Cirrus Logic had agreed to sell its semiconductor test operations assets in Austin, Texas to ChipPAC, Inc. (“ChipPAC”). In addition to the transfer of assets, Cirrus Logic and ChipPAC entered into a long-term strategic alliance, under which ChipPAC provides package development, wafer probe, assembly, final product test and distribution services to Cirrus Logic. We completed this transition at the end of calendar year 2004. In February 2005, we agreed to sell a portion of our test assets to Amkor Technology (“Amkor”) to further solidify our commitment to outsource our test operations and strategically align our operations geographically with our customers. We took additional steps in March 2005, when we sold another portion of our test floor assets to Premier Semiconductor Services (“Premier”). Both the Amkor and Premier asset sales position us to further outsource outsourced our test operations to geographically strategic locations. We expect that our efforts will result in lower test costs for our products in the future.
Patents, Licenses and Trademarks
     We rely on trade secret, patent, copyright and trademark laws to protect our intellectual property products and technology. We intend to continue this practice in the future to protect our products and technologies. As of March 26, 2005, we held 910 U.S. patents, 191 U.S. patent applications pending and various corresponding international patents and applications. Our U.S. patents expire in years 2006 through 2023.
     We have obtained U.S. federal registrations for the CIRRUS LOGIC ® , CIRRUS ® , CobraNet™, and CRYSTAL ® trademarks and our Cirrus Logic logo trademark. These U.S. registrations may be renewed as long as the marks continue to be used in interstate commerce. We have also filed or obtained foreign registration for these marks in other countries or jurisdictions where we conduct, or anticipate conducting, international business.
     To complement our own research and development efforts, we have also licensed and expect to continue to license, a variety of intellectual property and technologies important to our business from third parties.
Research and Development
     We concentrate our research and development efforts on the design and development of new products for each of our principal markets. We also fund certain advanced-process technology development, as well as other emerging product opportunities. Expenditures for research and development in fiscal years 2005, 2004, and 2003 were $66.8 million, $76.2 million, and $95.3 million, respectively. These amounts exclude amortization of acquired intangibles of $13.7 million, $14.4 million, and $17.8 million, in fiscal years 2005, 2004, and 2003, respectively. Our future success is highly dependent upon our ability to develop complex new products, to transfer new products to volume production in a timely fashion, to introduce them to the marketplace ahead of the competition and to have them selected for design into products of leading systems manufacturers. Our future success may also depend on assisting our customers with integration of our components into their new products, including providing support from the concept stage through design, launch and production ramp.
Competition
     Markets for our products are highly competitive and we expect that competition will continue to increase. We compete with other semiconductor suppliers that offer standard semiconductors, application-specific standard product (“ASSP”) and fully customized integrated circuits, including embedded software, chip and board-level products. A few customers also develop integrated circuits that compete with our products. Our strategy involves providing lower-cost versions of existing products and new, more advanced products for customers’ new designs.
     While no single company competes with us in all of our product lines, we face significant competition in each of our major product lines, as detailed above in our product line discussions. We expect to face additional competition from new entrants in our markets, which may include both large domestic and international IC manufacturers and smaller, emerging companies.
     The principal competitive factors in our markets include time to market; quality of hardware/software design and end-market systems expertise; price; product benefits that are characterized by performance, features, quality and compatibility with standards; access to advanced process and packaging technologies at competitive prices; and sales and technical support, including assisting our customers with integration of our components into their new products and providing support from the concept stage through design, launch and production ramp.
Page 7 of 71

Table of Contents

     Competition typically occurs at the design stage, where the customer evaluates alternative design approaches that require integrated circuits. Because our products have not been available from second sources, we generally do not face direct competition in selling our products to a customer once our integrated circuits have been designed into that customer’s system.
     Product life cycles vary greatly by product category. For example, many consumer electronic devices have shorter design-in cycles; therefore, our competitors have increasingly frequent opportunities to achieve design wins in next-generation systems. Conversely, this also provides us more frequent opportunities to displace competitors in products we have previously not been designed in. The Industrial and Automotive markets have longer life cycles, which provide longer revenue streams. In the event that competitors succeed in supplanting our products, our market share may not be sustainable and net sales, gross margins and earnings could be adversely affected.
Sales, Marketing and Technical Support
     Although we sell products worldwide, we sell principally in Asia. Export sales, which include sales to customers with manufacturing plants outside the United States, were 67 percent, 72 percent, and 77 percent in fiscal years 2005, 2004, and 2003, respectively. We maintain a worldwide sales force, which is intended to provide geographically specific selling support to our customers and specialized selling of product lines with unique customer bases.
     Our domestic sales force includes a network of regional direct sales offices located in California, Colorado, Massachusetts, Oregon and Texas. International sales offices and staff are located in Hong Kong, Japan, the People’s Republic of China, Singapore, South Korea, Taiwan and the United Kingdom. We supplement our direct sales force with external sales representatives and distributors. Our technical support staff is located in California, Colorado, Texas, South Korea, the People’s Republic of China, and Taiwan.
Backlog
     Sales are made primarily pursuant to standard short-term purchase orders for delivery of standard products. The quantity actually ordered by the customer, as well as the shipment schedules, are frequently revised, without significant penalty, to reflect changes in the customer’s needs. We utilize backlog as an indicator to assist us in production planning. However, backlog is influenced by several factors including market demand, pricing and customer order patterns in reaction to product lead times. Quantities actually purchased by customers, as well as prices, are subject to variations between booking and delivery to reflect changes in customer needs or industry conditions. As a result, we believe that our backlog at any given time is not a reliable indicator of future revenues.
Employees
     As of March 26, 2005, we had 603 full-time equivalent employees, of whom 58 percent were engaged in research and product development activities, 30 percent in sales, marketing, general and administrative activities and 12 percent in manufacturing-related activities. Our future success depends, in part, on our ability to continue to attract, retain and motivate highly qualified technical, marketing, engineering and administrative personnel.
     Due to the highly competitive nature of the marketplace that we operate in, we may from time-to-time lose key employees to our competitors. We have been able to hire qualified personnel in the past to fill open positions created by these occurrences, although there can be no assurance that we will be able to do this in the future. None of our employees are represented by collective bargaining agreements.
Risk Factors Affecting Our Business and Prospects
     Our business faces significant risks. The risk factors set forth below may not be the only risks that we face. Additional risks that we are not aware of yet or that currently are not significant may adversely affect our business operations. You should read the following cautionary statements in conjunction with the factors discussed elsewhere in this and other of Cirrus Logic’s filings with the Securities and Exchange Commission (“SEC”). These cautionary statements are intended to highlight certain factors that may affect the financial condition and results of operations of Cirrus Logic and are not meant to be an exhaustive discussion of risks that apply to companies such as ours.

The highly cyclical and volatile nature of our industry may affect our operating results.
     We are subject to business cycles and it is difficult to predict the timing, length, or volatility of these cycles. During downturns, customers usually reduce purchases, delay delivery of products, shorten lead times on orders and/or cancel orders. During upturns, our third party suppliers and contract manufacturers may have capacity or supply constraints that result in higher costs, longer lead times, and/or an inability to meet customer demand. These business cycles may create pressure on our sales, gross margins and/or operating results.
     We cannot assure that any future downturn or upturn will not have a material adverse effect on our business and results of operations. We cannot assure that we will not experience substantial period-to-period fluctuations in revenue due to general semiconductor industry conditions or other factors.
Our results may be affected by the fluctuation in sales in the consumer entertainment market.
     As we continue to sell products in the consumer entertainment market, we are more likely to be affected by seasonality in the sales of our products. In particular, a significant portion of consumer electronics products are sold worldwide during the back-to-school and fourth calendar quarter holiday seasons. As a result, we expect stronger sales of ICs into the consumer entertainment market to occur in our second and third fiscal quarters in anticipation of these seasons.
     Further, a decline in consumer confidence and consumer spending relating to economic conditions, terrorist attacks, armed conflicts, global health conditions and/or the political stability of countries in which we operate or sell into could have a material adverse effect on our business.
Our products are complex and could contain defects, which could result in material costs to us.
     Product development in the markets we serve is becoming more focused on the integration of multiple functions on individual devices. There is a general trend towards increasingly complex products. The greater integration of functions and complexity of operations of our products increases the risk that our customers or end users could discover latent defects or subtle faults after volumes of product have been shipped. This could result in:

 	•  	a material recall and replacement costs for product warranty and support,	
 	
 	•  	payments to our customer related to such recall claims as a result of various industry or business practices, or in order to maintain good customer relationships,	
 	
 	•  	an adverse impact to our customer relationships by the occurrence of significant defects,	
 	
 	•  	a delay in recognition or loss of revenues, loss of market share, or failure to achieve market acceptance, and	
 	
 	•  	a diversion of the attention of our engineering personnel from our product development efforts.	
     In addition, any defects or other problems with our products could result in financial or other damages to our customers who could seek damages from us for their losses. A product liability claim brought against us, even if unsuccessful, would likely be time consuming and costly to defend. In particular, the sale of systems and components into certain applications for the automotive industry involves a high degree of risk that such claims may be made.
     While we believe that we are reasonably insured against these risks and contractually limit our financial exposure, we cannot assure that we will be able to obtain insurance in amounts or of sufficient scope to provide us with adequate coverage against all potential liability. See “Legal Proceedings” later in this section for further information regarding outstanding litigation.
Our failure to develop and introduce new products on a timely basis could harm our operating results.
     Our success depends upon our ability to develop new products for new and existing markets, to introduce these products in a timely and cost-effective manner and to have these products gain market acceptance. The development of new products is highly complex and, from time-to-time, we have experienced delays in developing and introducing these new products. Successful product development and introduction depend on a number of factors, including:

 	•  	proper new product definition,	
 	
 	•  	timely completion of design and testing of new products,	
 	
 	•  	assisting our customers with integration of our components into their new products, including providing support from the concept stage through design, launch and production ramp,	
 	
 	•  	successfully developing and implementing the software necessary to integrate our products into our customers’ products,

 	•  	availability of wafer, assembly and test capacity,	
 	
 	•  	market acceptance of our products and the products of our customers, and	
 	
 	•  	obtaining and retaining industry certification requirements.	
     Although we seek to design products that have the potential to become industry standard products, we cannot assure that market leaders will adopt any products introduced by us, or that any products initially accepted by our customers that are market leaders will become industry standard products. Both revenues and margins may be materially affected if new product introductions are delayed, or if our products are not designed into successive generations of our customers’ products. We cannot assure that we will be able to meet these challenges, or adjust to changing market conditions as quickly and cost-effectively as necessary to compete successfully. Our failure to develop and introduce new products successfully could harm our business and operating results.
     Successful product design and development is dependent on our ability to attract, retain and motivate qualified design engineers, of which there is a limited number. Due to the complexity and variety of analog and high-precision analog and mixed-signal circuits, the limited number of qualified integrated circuit designers and the limited effectiveness of computer-aided design systems in the design of analog and mixed-signal ICs, we cannot assure that we will be able to successfully develop and introduce new products on a timely basis.
We have historically experienced fluctuations in our operating results and expect these fluctuations to continue in future periods.
     Our quarterly and annual operating results are affected by a wide variety of factors that could materially and adversely affect our net sales, gross margins and operating results. These factors include:

 	•  	the volume and timing of orders received,	
 	
 	•  	changes in the mix of our products sold,	
 	
 	•  	market acceptance of our products and the products of our customers,	
 	
 	•  	competitive pricing pressures,	
 	
 	•  	our ability to introduce new products on a timely basis,	
 	
 	•  	the timing and extent of our research and development expenses,	
 	
 	•  	the failure to anticipate changing customer product requirements,	
 	
 	•  	disruption in the supply of wafers, assembly or test services,	
 	
 	•  	certain production and other risks associated with using independent manufacturers, assembly houses and testers, and	
 	
 	•  	product obsolescence, price erosion, competitive developments and other competitive factors.	
Shifts in industry-wide capacity and our practice of purchasing our products based on sales forecasts may result in significant fluctuations in our quarterly and annual operating results.
     Shifts in industry-wide capacity from shortages to oversupply, or from oversupply to shortages, may result in significant fluctuations in our quarterly and annual operating results. We may order wafers and build inventory in advance of receiving purchase orders. Because our industry is highly cyclical and is subject to significant downturns resulting from excess capacity, overproduction, reduced demand, order cancellations, or technological obsolescence, there is a risk that we will forecast inaccurately and produce excess inventories of particular products.
     In addition, we generally order our products through non-cancelable purchase orders from third-party foundries based on our sales forecasts and our customers can generally cancel or reschedule orders they place with us without significant penalties. If we do not receive orders as anticipated by our forecasts, or our customers cancel orders that are placed, we may experience increased inventory levels.
     Due to the product manufacturing cycle characteristic of IC manufacturing and the inherent imprecision by our customers to accurately forecast their demand, product inventories may not always correspond to product demand, leading to shortages or surpluses of certain products. As a result of such inventory imbalances, future inventory write-downs and charges to gross margin may occur due to lower of cost or market accounting, excess inventory, and inventory obsolescence.

Strong competition in the semiconductor market may harm our business.
     The IC industry is intensely competitive and is frequently characterized by rapid technological change, price erosion and design, technological obsolescence, and a push towards IC component integration. Because of shortened product life cycles and even shorter design-in cycles in a number of the markets that we serve, our competitors have increasingly frequent opportunities to achieve design wins in next-generation systems. In the event that competitors succeed in supplanting our products, our market share may not be sustainable and our net sales, gross margins and operating results would be adversely affected. Additionally, further component integration could eliminate the need for our products.
     We compete in a number of fragmented markets. Our principal competitors in these markets include AKM Semiconductors, Analog Devices, Freescale Semiconductor, LSI Logic, Maxim, Micronas, Samsung Semiconductor, Texas Instruments, Wolfson Microelectronics and Zoran, many of whom have substantially greater financial, engineering, manufacturing, marketing, technical, distribution and other resources, broader product lines, greater intellectual property rights and longer relationships with customers. We also expect intensified competition from emerging companies and from customers who develop their own IC products. In addition, some of our current and future competitors maintain their own fabrication facilities, which could benefit them in connection with cost, capacity and technical issues.
     Increased competition could adversely affect our business. We cannot assure that we will be able to compete successfully in the future or that competitive pressures will not adversely affect our financial condition and results of operations. Competitive pressures could reduce market acceptance of our products and result in price reductions and increases in expenses that could adversely affect our business and our financial condition.
Our products may be subject to average selling prices that decline over short time periods. If we are unable to increase our volumes, introduce new or enhanced products with higher selling prices or reduce our costs, our business and operating results could be harmed.
     Historically in the semiconductor industry, average selling prices of products have decreased over time. If the average selling price of any of our products declines and we are unable to increase our unit volumes, introduce new or enhanced products with higher margins and/or reduce manufacturing costs to offset anticipated decreases in the prices of our existing products, our operating results may be adversely affected. In addition, because of procurement lead times, we are limited in our ability to reduce total costs quickly in response to any revenue shortfalls. Because of these factors, we may experience material adverse fluctuations in our future operating results on a quarterly or annual basis.
We have significant international sales, and risks associated with these sales could harm our operating results.
     Export sales, principally to Asia, include sales to U.S-based customers with manufacturing plants overseas and accounted for 67 percent, 72 percent and 77 percent of our net sales in fiscal years 2005, 2004 and 2003, respectively. We expect export sales to continue to represent a significant portion of product sales. This reliance on sales internationally subjects us to the risks of conducting business internationally, including political and economic stability and global health conditions, especially in Asia. For example, the financial instability in a given region, such as Asia, may have an adverse impact on the financial position of end users in the region, which could affect future orders and harm our results of operations. Our international sales operations involve a number of other risks, including:

 	•  	unexpected changes in government regulatory requirements,	
 	
 	•  	changes to countries’ banking and credit requirements	
 	
 	•  	changes in diplomatic and trade relationships,	
 	
 	•  	delays resulting from difficulty in obtaining export licenses for technology,	
 	
 	•  	tariffs and other barriers and restrictions,	
 	
 	•  	competition with foreign companies or other domestic companies entering the foreign markets in which we operate,	
 	
 	•  	longer sales and payment cycles,	
 	
 	•  	problems in collecting accounts receivable,	
 	
 	•  	political instability, and	
 	
 	•  	the burdens of complying with a variety of foreign laws.

     In addition, our competitive position may be affected by the exchange rate of the U.S. dollar against other currencies. Consequently, increases in the value of the dollar would increase the price in local currencies of our products in foreign markets and make our products relatively more expensive. Alternatively, decreases in the value of the dollar will increase the relative cost of our and our vendors’ operations that are based overseas. We cannot assure that regulatory, political and other factors will not adversely affect our operations in the future or require us to modify our current business practices.
Our international operations subject our business to additional political and economic risks that could have an adverse impact on our business.
     In addition to export sales constituting a majority of our net sales, we maintain significant international operations, including design, sales and technical support personnel. We are also using contract manufacturers in Asia for foundry, assembly and test operations. Expansion into this region has required and will continue to require significant management attention and resources. There are risks inherent in expanding our presence into foreign regions, including, but not limited to:

 	•  	difficulties in staffing and managing foreign operations,	
 	
 	•  	failure of foreign laws to adequately protect our U.S. intellectual property, patent, trademarks, copyrights, know-how and other proprietary rights,	
 	
 	•  	global health conditions and potential natural disasters,	
 	
 	•  	political and economic instability in international regions,	
 	
 	•  	international currency controls and exchange rate fluctuations,	
 	
 	•  	additional vulnerability from terrorist groups targeting American interests abroad, and	
 	
 	•  	legal uncertainty regarding liability and compliance with foreign laws and regulatory requirements.	
     Further, as we have completed the outsourcing of our test operations, we have become more dependent on third-party subcontractors in Asia for the assembly, packaging and testing of our products. Although we seek to reduce our dependence on our limited number of subcontractors, this concentration of subcontractors and manufacturing operations in Asia subjects us to the risks of conducting business in Asia. Disruption or termination of the assembly, packaging or testing of our products could occur and such disruptions could harm our business and operating results.
If we fail to attract, hire and retain qualified personnel, we may not be able to develop, market, or sell our products or successfully manage our business.
     Competition for personnel in our industry is intense. The number of technology companies in the geographic areas in which we operate is greater than it has been historically and we expect competition for qualified personnel to intensify. There are only a limited number of people in the job market with the requisite skills. Our Human Resources organization focuses significant efforts on attracting and retaining individuals in key technology positions. For example, start-up companies generally offer larger equity grants to attract individuals from more established companies. The loss of the services of key personnel or our inability to hire new personnel with the requisite skills could restrict our ability to develop new products or enhance existing products in a timely manner, sell products to our customers, or manage our business effectively.
We rely on independent foundries to manufacture our products, which subject us to increased risks.
     We rely on independent foundries to manufacture all of our wafers. Our reliance on these foundries involves risks and uncertainties, including:

 	•  	the possibility of an interruption or loss of manufacturing capacity,	
 	
 	•  	the lack of control over delivery schedules, quality assurance, manufacturing yields and costs,	
 	
 	•  	the inability to secure necessary capacity to meet customer demand,	
 	
 	•  	the possible misappropriation of our intellectual property, and	
 	
 	•  	the inability to reduce our costs as quickly as competitors who manufacture their own products and are not bound by set prices.	
     Market conditions could result in wafers being in short supply and prevent us from having adequate supply to meet our customer requirements. In addition, any prolonged inability to utilize third-party foundries because of fire, natural disaster, or otherwise, would have a material adverse effect on our financial condition and results of operations. If we are not able to obtain additional foundry capacity as required, our relationships with our customers
Page 12 of 71

Table of Contents

would be harmed and, consequently, our sales would likely be reduced and we may be forced to purchase wafers from higher-cost suppliers or to pay expediting charges to obtain additional supply, if we are able to acquire wafers at all.
     In order to secure additional foundry capacity, we may enter into contracts that commit us to purchase specified quantities of wafers over extended periods. In the future, we may not be able to secure sufficient capacity with foundries in a timely fashion (or at all) and such arrangements, if any, may not be on terms favorable to us. Moreover, if we are able to secure foundry capacity, we may be obligated to utilize all of that capacity or incur penalties. These penalties may be expensive and could harm our financial results.
Because we are dependent on our subcontractors in Asia to perform key manufacturing functions for us, we are subject to political and economic risks that could disrupt the assembly, packaging, or testing of our products.
     We depend on third-party subcontractors in Asia for the assembly, packaging and testing of our products. International operations and sales may be subject to political and economic risks, including changes in current tax laws, political instability, global health conditions, currency controls, exchange rate fluctuations and changes in import/export regulations, tariff and freight rates, as well as the risks of natural disaster. Although we seek to reduce our dependence on our limited number of subcontractors, this concentration of subcontractors and manufacturing operations in Asia subjects us to the risks of conducting business internationally, including political and economic conditions in Asia. Disruption or termination of the assembly, packaging or testing of our products could occur and such disruptions could harm our business and operating results.
Failure to manage our distribution channel relationships could adversely affect our business.
     In fiscal years 2005, 2004 and 2003, sales to our distributors accounted for 62 percent, 66 percent and 59 percent, respectively, of our total net sales. The future of our business, as well as the future growth of our business, will depend in part on our ability to manage our relationships with current and future distributors and external sales representatives and to develop additional channels for the distribution and sale of our products. The inability to successfully manage these relationships could adversely affect our business.
We may acquire other companies or technologies, which may create additional risks associated with our ability to and successfully integrate them into our business.
     We continue to consider future acquisitions of other companies, or their technologies or products, to improve our market position, broaden our technological capabilities and expand our product offerings. However, we may not be able to acquire, or successfully identify, the companies, products or technologies that would enhance our business.
     In addition, if we are able to acquire companies, products or technologies, we could experience difficulties in integrating them. Integrating acquired businesses involves a number of risks, including, but not limited to:

 	•  	the potential disruption of our ongoing business,	
 	
 	•  	unexpected costs or incurring unknown liabilities,	
 	
 	•  	the diversion of management resources from other business concerns while involved in identifying, completing, and integrating acquisitions,	
 	
 	•  	the inability to retain the employees of the acquired businesses,	
 	
 	•  	difficulties relating to integrating the operations and personnel of the acquired businesses,	
 	
 	•  	adverse effects on the existing customer relationships of acquired companies,	
 	
 	•  	the potential incompatibility of business cultures,	
 	
 	•  	adverse effects associated with entering into markets and acquiring technologies in areas in which we have little experience, and	
 	
 	•  	acquired intangible assets becoming impaired as a result of technological advancements, or worse-than-expected performance of the acquired company.	
     If we are unable to successfully address any of these risks, our business could be harmed.
The divestiture of our video business subjects us to additional risks and uncertainties that could adversely affect our business.
     On May 24, 2005, we signed a definitive agreement to sell the assets associated with our digital video product line to Magnum Semiconductor Inc., a privately held company formed by an investment group led by Investcorp Technology Ventures II, L.P. The announced transaction is subject to several significant closing conditions. Our
Page 13 of 71

Table of Contents

failure to meet any of these closing conditions could result in the transaction not being consummated, which could have a material adverse effect on our business.
     Even if we are successful in divesting this product line, there can be no assurance that we will be able to achieve profitability, strengthen our core operations, compete more effectively in existing or new markets, or actually increase stockholder value after the transaction. Further, such divestiture transactions may entail risks and uncertainties in addition to those which may result from the divestiture-related changes in our business operations, including but not limited to extraordinary transaction costs, unknown indemnification liabilities and unforeseen administrative complications, any of which could result in reduced revenues, increased charges or post-transaction administrative costs, or could otherwise have a material adverse effect on our business, financial condition or results of operations.
We may be unable to protect our intellectual property rights from third-party claims and litigation .
     Our success depends on our ability to obtain patents and licenses and to preserve our other intellectual property rights covering our manufacturing processes, products and development and testing tools. We seek patent protection for those inventions and technologies for which we believe such protection is suitable and is likely to provide a competitive advantage to us. We also rely substantially on trade secrets, proprietary technology, non-disclosure and other contractual agreements, and technical measures to protect our technology and manufacturing knowledge. We work actively to foster continuing technological innovation to maintain and protect our competitive position. We cannot assure that steps taken by us to protect our intellectual property will be adequate, that our competitors will not independently develop or patent substantially equivalent or superior technologies or be able to design around our patents, or that our intellectual property will not be misappropriated. In addition, the laws of some foreign countries may not protect our intellectual property as well as the laws of the United States. See “Legal Proceedings.”
Potential intellectual property claims and litigation could subject us to significant liability for damages and could invalidate our proprietary rights.
     The IC industry is characterized by frequent litigation regarding patent and other intellectual property rights. We may find it necessary to initiate a lawsuit to assert our patent or other intellectual property rights. These legal proceedings could be expensive, take significant time and divert management’s attention from other business concerns. We cannot assure that we will ultimately be successful in any lawsuit, nor can we assure that any patent owned by us will not be invalidated, circumvented, or challenged. We cannot assure that rights granted under the patent will provide competitive advantages to us, or that any of our pending or future patent applications will be issued with the scope of the claims sought by us, if at all.
     As is typical in the IC industry, we and our customers have from time to time received and may in the future receive, communications from third parties asserting patents, mask work rights, or copyrights. In the event third parties were to make a valid intellectual property claim and a license was not available on commercially reasonable terms, our operating results could be harmed. Litigation, which could result in substantial cost to us and diversion of our management, technical and financial resources, may also be necessary to defend us against claimed infringement of the rights of others. An unfavorable outcome in any such suit could have an adverse effect on our future operations and/or liquidity.
If our products do not conform to or support certain industry standards, our products may not be accepted by the market and our business may be harmed.
     Generally, our products comprise only a part of our customers’ product. All components of such devices must 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 and our business would be harmed.
     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. We may not be successful in developing or using new technologies or in developing new products or product enhancements that achieve market acceptance. Our pursuit of necessary technological advances may require substantial time and expense.

Table of Contents

If we are unable to make continued substantial investments in research and development, we may not be able to develop and sell new products, which would likely harm our future operating results.
     We make significant investments in research and development activities to develop new and enhanced products and solutions. If we fail to make sufficient investments in research and development programs, new technologies could render our current and planned products obsolete, and our business could be harmed.
Our stock price may be volatile.
     The market price of our common stock fluctuates significantly. This fluctuation is the result of numerous factors, including:

 	•  	actual or anticipated fluctuations in our operating results,	
 	
 	•  	announcements concerning our business or those of our competitors, customers or suppliers,	
 	
 	•  	changes in financial estimates by securities analysts or our failure to perform as anticipated by the analysts,	
 	
 	•  	announcements regarding technological innovations or new products by us or our competitors,	
 	
 	•  	announcements by us of significant acquisitions, strategic partnerships, joint ventures, or capital commitment,	
 	
 	•  	announcements by us of significant divestitures or sale of certain assets or intellectual property,	
 	
 	•  	litigation arising out of a wide variety of matters, including, among others, employment matters and intellectual property matters,	
 	
 	•  	departure of key personnel,	
 	
 	•  	single significant shareholders selling for reasons unrelated to the business,	
 	
 	•  	general assumptions made by securities analysts,	
 	
 	•  	general conditions in the IC industry, and	
 	
 	•  	general market conditions and interest rates.	
We have provisions in our charter, and are subject to certain provisions of Delaware law, which could prevent, delay or impede a change of control of our company. These provisions could affect the market price of our stock.
     Certain provisions of our Certificate of Incorporation and By-Laws, and Delaware law could make it more difficult for a third party to acquire us, even if our stockholders support the acquisition. These provisions include:

 	•  	the inability of stockholders to call a special meeting of stockholders;	
 	
 	•  	a prohibition on stockholder action by written consent; and	
 	
 	•  	a requirement that stockholders provide advance notice of any stockholder nominations of directors or any proposal of new business to be considered at any meeting of stockholders.	
     We are also subject to the anti-takeover laws of Delaware that may prevent, delay or impede a third party from acquiring or merging with us, which may adversely affect the market price of our common stock.
ITEM 2. Properties
     The company does not own any real estate. However, as of May 1, 2005, our principal leased facilities, located in Austin, Texas, consisted of approximately 251,000 square feet of office and test space, which have leases that expire from 2005 to 2012, excluding renewal options. This leased space is used for product development and testing, sales, marketing and administration. This includes our headquarters and engineering facility, which has 197,000 square feet. Our total leased space in Austin, Texas includes 16,000 square feet that we have subleased through July 2005 and an additional 33,000 square feet subleased through April 2007.
     The lease agreement for our headquarter and engineering facility includes a potential obligation to enter into another lease agreement for a period of 10 years for an additional 64,000 square feet in a new building to be built on property next to our current facility. This obligation was contingent upon construction beginning on the new facility before November 10, 2004. On September 14, 2004, our landlord provided us notice that it had elected to construct the new building. However, as of May 27, 2005, actual construction on the new building had not commenced. On November 12, 2004, we filed suit against our landlord in the state district court of Travis County, Texas seeking declaratory relief as to our obligations under the current operating lease agreement. Specifically, we seek a
Page 15 of 71

Table of Contents

declaration that we have no obligation to lease an additional 64,000 square feet of space because the landlord did not commence construction of the new facility before November 10, 2004. Trial has been set in this matter for December 2005. In the event that the court determines that the owner of the property has strictly complied with all notices and conditions precedent to entering a new lease, we estimate that the yearly minimum future lease payments could be as much as $1.7 million. In addition, we may be required to provide a cash deposit of $200,000 as well as segregating and restricting an additional $3 million of our available cash balance in the form of a letter of credit. If we are required to enter into a new lease, we are unable to estimate when these potential obligations would begin because it is uncertain when construction will actually be completed.
     We also lease facilities in Fremont, California. These facilities consist of approximately 430,000 square feet of leased office and engineering space, which have leases that expire from 2006 to 2009, excluding renewal options. In connection with our facilities consolidation activities, which began in fiscal year 1999 concurrent with our move of headquarters from California to Texas, we have subleased approximately 263,000 square feet of this office space. During fiscal year 2004, our California lease space was reduced by approximately 55,000 square feet as a result of the expiration of a lease.
     During fiscal year 2005, we completed a lease buyout of our Broomfield, Colorado location to reduce our overall office rental space in Colorado by approximately 50,000 square feet. In April 2005, we further reduced our leased office space by approximately 4,000 square feet when we exited our Ft. Wayne, Indiana site.
     Below is a detailed schedule that identifies our other occupied leased property locations as of May 1, 2005 with various lease terms through fiscal year 2010:

ITEM 3. Legal Proceedings
Fujitsu
     On October 19, 2001, we filed a lawsuit against Fujitsu, Ltd. (“Fujitsu”) in the United States District Court for the Northern District of California. We asserted claims for breach of contract and anticipatory breach of contract and we sought damages in excess of $46 million. The basis for our complaint was Fujitsu’s refusal to pay for hard disk drive-related chips delivered to and accepted by it in fiscal year 2002. On December 17, 2001, Fujitsu filed an answer and a counterclaim. Fujitsu alleged claims for breach of contract, breach of warranty, quantum meruit/equitable indemnity and declaratory relief. The basis for Fujitsu’s counterclaim was the allegation that certain chips that we sold to Fujitsu were defective and allegedly caused Fujitsu’s hard disk drives to fail. The counterclaim did not specify the damages Fujitsu seeks, other than to allege it has sustained “tens of millions” of dollars in damages. To facilitate the resolution of all claims in one lawsuit, including our claims against potentially responsible third parties, we agreed with Fujitsu to realign our claims so that Fujitsu is the plaintiff and we are the defendant and counterclaimant. This realignment allowed Fujitsu and us to file in the same lawsuit third-party claims alleging breach of contract and warranty against Amkor Technology, Inc., (“Amkor”) the company that recommended and sold to us the packaging materials that caused the alleged defects in our chips. Amkor filed an answer to our third-party claim and a third-party complaint for implied contractual indemnity and breach of warranties against Sumitomo Bakelite Co., Ltd., (“Sumitomo”) the company that sold the allegedly defective molding compound used in these packaging materials.
Page 16 of 71

Table of Contents

     On December 5, 2003, for reasons related to the potential lack of jurisdiction for certain claims in federal district court, Fujitsu filed a complaint in California state court alleging claims substantially similar to those filed against us in district court and, in addition, alleging fraud and other related claims against Amkor and Sumitomo. On December 23, 2003, we filed a cross-complaint in California state court alleging the same claims against Fujitsu as we alleged in federal district court and further alleging fraud and other related claims against Amkor and Sumitomo based on their alleged knowledge that the molding compound used in the packaging materials sold to us was defective. On May 10, 2004, the state court issued an order finding the facts supporting the new fraud and negligent misrepresentation causes of action against Amkor and Sumitomo set forth in our cross-complaint insufficient. On June 18, 2004, we filed an amended cross complaint asserting the same fraud and negligent misrepresentation claims against Amkor and Sumitomo in more detail. On August 24, 2004, the court again found the fraud and negligent misrepresentation claims in our cross-complaint were insufficient and granted 30 days for us to file another amended cross-complaint. We filed a second amended cross complaint on October 4, 2004, in which we alleged additional factual detail in support of these claims. On November 23, 2004, the court found that we had alleged sufficient facts to support our fraud and negligent misrepresentation claims against Amkor and Sumitomo.
     To address the claims of all parties and for reasons of judicial economy, the parties jointly moved to stay the federal district court action pending resolution of the state court action. The trial in state court was originally set for January 31, 2005, but was rescheduled by the court on September 21, 2004 for May 2, 2005.
     On April 28, 2005, before the rescheduled trial date, Cirrus Logic, Fujitsu, Amkor, Sumitomo, and Cirrus Logic’s insurance carriers reached an agreement to settle through an arbitration process and release all pending claims related to the alleged failure of certain semiconductor integrated circuits sold by Cirrus Logic to Fujitsu. These releases included releases between our insurance carriers and us for any claims related to the litigation with Fujitsu. As part of the settlement, Fujitsu is to receive $45 million from Sumitomo, $40 million from Amkor, and $40 million from Cirrus Logic’s insurance carriers. Fujitsu agreed to pay us a lump sum in the amount of $25 million. We anticipate the final settlement documents will be completed and payment will be received prior to the end of June 2005.
St. Paul Fire and Marine Insurance Company
     On June 9, 2004, we filed a complaint for declaratory relief against St. Paul Fire and Marine Insurance Co. (“St. Paul”) in the United States District Court, Northern District of California. Specifically, the complaint seeks a judicial determination and declaration that the Technology Commercial General Liability Protection (“CGL”) coverage under an insurance policy issued to us by St. Paul provides Cirrus Logic with insurance coverage for Cirrus Logic’s defense of claims brought by Fujitsu in the previously referenced matter. Pursuant to our CGL policy, the costs and expenses associated with defending our lawsuit against Fujitsu would be covered, but would not reduce the policy coverage limits. On August 23, 2004, St. Paul answered the complaint, denying that it was obligated to defend us under the CGL policy.
     Based on the settlement and releases agreed to by the insurance carriers as set forth in the previously referenced matter, we anticipate that, after documentation of the settlement, we will dismiss this case after the insurance carriers have paid Fujitsu and Fujitsu has paid us pursuant to a final settlement agreement.
Wolfson Microelectronics
     On October 9, 2003, we filed a lawsuit against Wolfson Microelectronics, plc, a United Kingdom company and Wolfson Microelectronics Ltd., a Delaware corporation, (collectively “Wolfson”) in the U.S. District Court for the Southern District of California. We alleged that several Wolfson products that incorporate digital-to-analog converters (“DACs”) infringe on our U.S. Patent Nos. 6,492,928 and 6,011,501. We were seeking damages and requesting a permanent injunction against Wolfson from making, using, offering to sell or selling in the U.S. or importing into the U.S. any infringing products. On December 2, 2003, in response to our complaint, Wolfson filed an answer and a counterclaim against us alleging, among other things, unfair competition, tortious interference with prospective economic advantage and tortious interference with contractual relationships. Wolfson’s claims were based primarily on our alleged bad faith in filing suit against Wolfson with the alleged knowledge that one of the two asserted patents was invalid. On April 2, 2004, the district court dismissed Wolfson’s counterclaims for failure to state a claim, although the district court granted leave to amend their complaint. On April 30, 2004, Wolfson amended its counterclaims to include additional allegations concerning alleged communications by Cirrus Logic with Bose Corporation and Argus Electronics relating to Wolfson’s ability to continue to provide Wolfson audio DACs to these customers in the future.
     In addition, on October 14, 2003, we filed a complaint requesting that the U.S. International Trade Commission (the “ITC”) initiate an investigation of Wolfson Microelectronics, plc, for violation of Section 337 of the Tariff Act of 1930, in the importation, sale for importation and sale in the U.S. after importation of certain digital-to-analog

converters and other products containing these converters. In our complaint, we asked the ITC to investigate whether certain Wolfson products infringe on one or more of the claims of U.S. Patent No. 6,492,928. On November 10, 2003, the ITC instituted an investigation into Wolfson’s actions based on our allegations. On December 9, 2003, we also requested the ITC to further investigate whether certain Wolfson products infringed on one or more of the claims of U.S. Patent No. 6,011,501. On December 29, 2003, the ITC included our allegations of infringement with respect to U.S. Patent No. 6,011,501 into its investigation. With respect to both patents, we were seeking a permanent exclusion order banning the importation into the U.S. of the allegedly infringing products and a cease-and-desist order halting the sale of these infringing products, as well as other relief the ITC deems appropriate.
     On November 16, 2004, an administrative law judge determined that both patents asserted against Wolfson were valid and infringed. However, with respect to U.S. Patent No. 6,492,928, the administrative law judge also determined that the patent was not enforceable due to our failure to provide certain information to the Patent and Trademark Office as part of our efforts to obtain the patent. The ITC has further determined that it will not review that decision.
     On February 11, 2005, the ITC issued its determination as to the appropriate remedy that we are entitled to with respect to U.S. Patent No. 6,011,501. Specifically, the ITC issued a limited exclusion order prohibiting the importation of three models of Wolfson’s DACs that infringe the ‘501 patent.
     We settled all of our outstanding litigation matters with Wolfson on March 24, 2005. Under the settlement agreement, the parties agreed to withdraw all outstanding claims and counterclaims in the U.S. District Court proceedings. In addition, the parties submitted an application to the ITC for the withdrawal of the exclusion order that the ITC issued in February 2005 in relation to the ‘501 patent. As part of the settlement, the parties have agreed not to assert any patents against each other for a period of three years. In addition, Wolfson agreed not to make, use, sell, offer for sale, and/or import into the United States any DACs that practiced the ‘501 patent. No payments were made, or will be made, by either party as part of the settlement.
Silvaco Data Systems
     On December 8, 2004, Silvaco Data Systems (“Silvaco”) filed suit against us, and others, alleging misappropriation of trade secrets, conversion, unfair business practices, and civil conspiracy. Silvaco’s complaint stems from a trade secret dispute between Silvaco and a software vendor, Circuit Semantics, Inc., who supplies us with certain software design tools. Silvaco alleges that our use of Circuit Semantic’s design tools infringes upon Silvaco’s trade secrets and that we are liable for compensatory damages in the sum of $10 million. Silvaco has not indicated how it will substantiate this amount of damages and we are unable to reasonably estimate the amount of damages, if any.
     On January 25, 2005, we answered Silvaco’s complaint by denying any wrong-doing. In addition, we filed a cross-complaint against Silvaco alleging breach of contract relating to Silvaco’s refusal to provide certain technology that would enable us to use certain unrelated software tools.
     We intend to defend the lawsuit vigorously. In addition, Circuit Semantics is obligated to defend and indemnify us pursuant to our license agreement with them for the software. However, we cannot predict the ultimate outcome of this litigation and we are unable to estimate any potential liability we may incur.
Facilities Under Operating Lease Agreements
     We lease our facilities under operating lease agreements. Our principal facility, located in Austin, Texas, is 197,000 square feet and houses our headquarters and engineering facility. The lease agreement for this facility includes a potential obligation to enter into another lease agreement for a period of 10 years for an additional 64,000 square feet in a new building to be built on property next to our current facility. This obligation was contingent upon construction beginning on the new facility before November 10, 2004. On September 14, 2004, our landlord provided us notice that it had elected to construct the new building. However, as of May 27, 2005, actual construction on the new building had not commenced. On November 12, 2004, we filed suit against our landlord in the state district court of Travis County, Texas seeking declaratory relief as to our obligations under the current operating lease agreement. Specifically, we seek a declaration that we have no obligation to lease an additional two floors of space because the landlord did not commence construction of the new facility before November 10, 2004. Trial has been set in this matter for December 2005.
     In the event that the court determines that the owner of the property has strictly complied with all notices and conditions precedent to entering a new lease, we estimate that the yearly minimum future lease payments could be as much as $1.7 million. In addition, we may be required to provide a cash deposit of $200,000 as well as segregating and restricting an additional $3 million of our available cash balance in the form of a letter of credit. If we are

required to enter into a new lease, we are unable to estimate when these potential obligations would begin because it is uncertain when construction will actually be completed.
Other Claims
     From time-to-time, other various claims, charges and litigation are asserted or commenced against us arising from, or related to, contractual matters, intellectual property, employment disputes, as well as other issues. Frequent claims and litigation involving these types of issues are not uncommon in the integrated circuit (“IC”) industry. As to any of these claims or litigation, we cannot predict the ultimate outcome with certainty.

     Certain reclassifications have been made to conform to the fiscal year 2005 presentation. These reclassifications had no effect on the results of operations or stockholders’ equity, other than as disclosed in Note 16 in the Notes to our Consolidated Financial Statements contained in “Item 8 – Financial Statements and Supplementary Data.”
Overview
     We were incorporated in California in 1984 and became a public company in 1989. Through most of our corporate existence, we provided integrated circuits (“ICs”) for personal computer applications, including personal computer (“PC”) graphics and storage. Several years ago, we refocused our business efforts away from these areas, which we believed had become commodity-like in terms of pricing and offered diminished opportunities for sustained product differentiation and profitability. We have reinforced our commitment to achieving profitability by taking strategic actions during fiscal year 2005 and the first part of fiscal year 2006 to improve our top and bottom line growth. Some actions we have taken in the past year include, but are not limited to: (1) aligning our resources during this current year to improve efficiencies by implementing a product line structure focusing on four product lines including Mixed-Signal products, Embedded products, Industrial products and Video products, (2) announcing our intentions to divest ourselves of our video product line to focus on our core strengths, and (3) completing the outsourcing of our test operations to drive us to a completely fabless business model; and (4) settling significant outstanding legal disputes that tended to drain key resources and divert our focus from managing the business.
     During fiscal year 2004, we settled and received $45 million from an outstanding commercial litigation with a storage product manufacturer Western Digital Corp., we settled and received a total of $14.4 million after expenses from two PC graphic IC patent infringement lawsuits with ATI Technologies and nVidia Corporation and we received a net $17 million related to a transaction with Broadcom Corporation for certain U.S. and foreign patents. Further, we also benefited from the sale of marketable securities for $12 million.
     Although we continue to defend our patents and investigate the potential for leveraging our intellectual property portfolio, we do not anticipate the same level of benefits we have received in the past to reoccur in the future. We have directed our efforts to become a leader in digital audio and high-performance analog and mixed-signal ICs for consumer entertainment, automotive entertainment and high-precision industrial measurement applications. We offer more than 600 products to over 3,000 end customers worldwide through both direct and indirect sales channels. We target both large existing and emerging growth markets that derive value from our expertise in advanced analog and mixed-signal design processing, systems-level integrated circuit engineering and embedded software. End products incorporating our ICs are marketed by many of the world’s leading electronics companies, including Bose, Creative Technologies, Harman/Kardon, LG Electronics, Panasonic, Philips, Pioneer, Samsung, Siemens, Sony, Thomson S.A. and Yamaha, among others.
     Our core product lines include our analog and mixed-signal products for consumer, industrial, automotive, and other analog and mixed-signal products; digital home audio processors and digital portable processors; commercial audio processors; automotive audio solutions; and embedded processors. Some common items our audio mixed-signal products may be found in include amplifiers, AVRs, DVD players and recorders, DVD receivers, set-top boxes, game consoles, car audio systems and satellite radios. The balance of our analog and mixed-signal IC components are primarily sold into industrial measurement applications, such as temperature gauges for industrial use, seismic devices for oil field and seismology applications and high-precision weigh scales for commercial and scientific use.
     Our video product line, which we recently announced that we plan to divest from our business, includes our digital video recorder and home theater recorder products. We believe that we have established a leading DVD recording merchant market position. Consumer DVD recorders, including standalone DVD recorders, optical and hard-drive-enabled combination DVD recorders and home theater recorders, which record video digitally, are expected to become one of the fastest growing segments in digital entertainment during the next several years. According to market research analysts, worldwide unit sales for all forms of DVD recorders are projected to be up to potentially over 50 million units by 2006. By divesting the video product line, we intend to focus on our core analog, mixed-signal and embedded IC product lines for audio and industrial markets. With this increased focus, we believe that we will be poised to leverage our intellectual property and high-margin analog product lines to drive growth and sustainable profitability. Further, we believe that we will minimize certain risks previously associated with the video

products, including more cyclicality in growth patterns as well as having stronger competition due to shorter design cycles than our core mixed signal and analog product lines.
     We maintain sales, design and technical support personnel in the U.S. and other locations near our customers. We have strategically aligned our personnel to provide better support to our growing base of system solution customers, most of which maintain design and/or manufacturing sites outside of the United States. We intend to continue to evaluate our employee headcount in these locations in order to maintain our high level of commitment and support to our customers.
     We also contract with third-parties for all of our wafer fabrication, assembly and testing operations. Our supply chain management organization qualifies each product, participates in process and package development, defines and controls the manufacturing process at our suppliers, develops test programs and performs production testing of products in accordance with our ISO-certified quality management system. Our fabless manufacturing strategy allows us to concentrate on our design strengths, minimize fixed costs and capital expenditures, access advanced manufacturing facilities and provides flexibility on sourcing through multiple qualified vendors. We recently completed the outsourcing of our test facilities with various vendors including ChipPAC, Premier and Amkor.
     During fiscal year 2005, we were able to realize a tax benefit of approximately $21 million due to the expiration of certain statutes related to domestic and foreign tax liabilities. Although we did not pay U.S. income taxes in fiscal year 2005 and we do not expect to incur regular U.S. income taxes in fiscal year 2006 as we have a large net operating loss (“NOL”) carry forward to offset tax liabilities for U.S.-sourced income, we do not expect to continue to see the same level of tax benefits during fiscal year 2006. We may incur taxes in many of the international and U.S. state tax jurisdictions in which we operate. We have identified tax matters in several of these localities and have reserved for those exposures. See Note 15 in the Notes to our Consolidated Financial Statements contained in “Item 8 — Financial Statements and Supplementary Data” for further detail.

Net Sales
     Net sales for fiscal year 2005 decreased $1.4 million, or 1 percent, to $194.9 million from $196.3 million in fiscal year 2004. Net sales from our Industrial products were up $7.9 million in fiscal year 2005 due to increased demand in our seismic business. These increases were partially offset by a decrease of $6.4 million in net sales of
Page 22 of 71

Table of Contents

our Video products in fiscal year 2005 from the prior year. The decrease in our video products was primarily attributable to missed design wins due to software compatibility issues coupled with a decrease in sales into the DVD player market, as manufacturers discontinued producing this highly commoditized product. Net sales from Mixed-Signal products declined $1.8 million due primarily to a continued decrease in demand for personal computer audio components, a market we have de-emphasized, while Embedded product net sales increased $0.3 million during fiscal year 2005. Net sales from our other products declined approximately $1.4 million in fiscal year 2005 from the comparable period of the prior year due to sales related to a discontinued product line in fiscal year 2004.
     Net sales for fiscal year 2004 decreased $65.7 million, or 25 percent, to $196.3 million from $262.0 million in fiscal year 2003. Net sales from our Embedded products were down in fiscal year 2004 by $27.2 million from fiscal year 2003 due to a decline in demand for certain older DSPs and converters. Net sales from our Mixed-Signal products were down an additional $34.5 million as a result of lower sales of personal computer audio components, a market that we have de-emphasized. These decreases were partially offset by increased demand for our audio converters, and an increase of $5.3 million in net sales of our Industrial products. Additionally, net sales of our Video products increased $16.3 million in fiscal year 2004 from the comparable period of the prior year. The increase in net sales of our Video products was primarily due to emerging sales in the DVD recorder market, partially offset by decreases in sales of video decoders for prior generation DVD players. Net sales from our other products declined $25.6 million in fiscal year 2004 from the comparable period of the prior year. The majority of this decline was attributed to a single device from our game console products that were made under a volume purchase agreement, the terms of which were fulfilled in the fourth quarter of fiscal year 2003.
     Export sales, principally to Asia, including sales to U.S.-based customers with manufacturing plants overseas, were approximately $130.6 million in fiscal year 2005, $141.4 million in fiscal year 2004, and $201.1 million in fiscal year 2003. Export sales to customers located in Asia were 52 percent, 59 percent, and 68 percent of net sales in fiscal years 2005, 2004, and 2003, respectively. All other export sales were 15 percent, 13 percent, and 9 percent of net sales in fiscal years 2005, 2004, and 2003, respectively.
     Our sales are denominated primarily in U.S. dollars. During fiscal years 2005, 2004, and 2003, we did not enter into any foreign currency hedging contracts.
     During fiscal year 2005, sales to one of our distributors, Memec Group Holdings Limited, accounted for 27 percent of net sales. In fiscal year 2004, sales to Memec Group Holdings Limited accounted for 20 percent of net sales. In fiscal year 2003, sales to Memec Group Holdings Limited accounted for approximately 15 percent while sales to Thomson S.A. accounted for approximately 12 percent of net sales. No other customers or distributors accounted for 10 percent or more of net sales in fiscal years 2005, 2004, or 2003. The loss of a significant customer or a significant reduction in such a customer’s orders could have an adverse effect on our sales. Our sales to Thomson S.A. primarily consisted of DVD drive manager devices that were included in game console products. These game console sales were made under a volume purchase agreement the terms of which were fulfilled during fiscal year 2003.

     Gross margin was 48 percent in fiscal year 2005, down from 51 percent in fiscal year 2004. In fiscal year 2005, we completed the transition of our test operations to outside third party providers. During this transition, we did not decrease our internal test operations as much as we had anticipated, which resulted in higher internal overhead costs. This increase in internal overhead resulted in a 1.6 percent decrease in our gross margin. Further, the sale of product that had been written down in prior fiscal years contributed approximately $2.6 million, or 1.4 percent of gross margin percentage compared with a 1.7 percent contribution to margin from fiscal year 2004. Overall, inventory charges increased $1.4 million, or 0.7 percent in fiscal year 2005 compared with the prior year, mainly due to write down charges associated with video related products. Additionally, 0.4 percent of the 2004 gross margin percentage was related to non-recurring items.
     Gross margin was 51 percent in fiscal year 2004, up from 50 percent in fiscal year 2003. In fiscal year 2004, the sale of product that had been written down in prior years contributed approximately $3.3 million, or 1.7 percent of gross margin percentage. Additionally, we reversed an accrual recorded in a prior year related to a return material authorization (“RMA”) that was submitted for return and was subsequently determined to not be valid. This reversal of approximately $1.5 million contributed 0.4 percent of gross margin.

     We continue to see increased lead times from our various fabrication, assembly and test service providers. An increase in procurement lead times and/or decrease in capacity may cause our costs to increase, which may slow our gross margin growth in fiscal year 2006.
Research and Development Expenses
     Research and development expenses decreased $9.3 million from the prior year primarily due to the fiscal year 2005 cost reductions and the realization of the full-year impact of the fiscal year 2004 cost reductions. Research and development expenses decreased as a percentage of net sales from 39 percent in fiscal year 2004, to 34 percent in fiscal year 2005.
     Research and development expenses decreased $19.1 million in fiscal year 2004 from the prior year. This decrease was primarily due to the fiscal year 2004 cost reductions and the realization of the full-year impact of the fiscal year 2003 cost reduction efforts. Despite the decline in absolute dollar amounts, research and development expenses increased as a percentage of net sales from 36 percent in fiscal year 2003, to 39 percent in fiscal year 2004, due to our cost reduction efforts not falling in the same proportion as our decline in net sales year over year as we continued to invest in new products.
Selling, General and Administrative Expenses
     Selling, general and administrative expenses decreased $9.1 million in fiscal year 2005 from the prior year. Selling, general and administrated expenses benefited in fiscal year 2005 from a $3.0 million release of a use tax accrual coupled with a refund of $2.3 million related to recovered foreign goods and sales tax. Further, selling, general and administrative also benefited from the realization of the full-year impact of the fiscal year 2004 cost reduction efforts. Selling, general and administrative expenses decreased as a percentage of net sales from 26 percent in fiscal year 2004 to 22 percent in fiscal year 2005.
     Selling, general and administrative expenses decreased $22.1 million in fiscal year 2004 from the prior year, primarily due to the fiscal year 2004 cost reductions and the realization of the full-year impact of the fiscal year 2003 cost reduction efforts. Selling, general and administrative expenses also decreased as a percentage of net sales from 28 percent in fiscal year 2003 to 26 percent in fiscal year 2004.
Restructuring Costs and Other, Net
     During fiscal year 2005, we recorded a net restructuring charge of $1.5 million in operating expenses for facility consolidations primarily in California and Texas, an impairment charge of $5.1 million for technology licenses and equipment that will no longer be used due to our workforce reductions and a charge of $2.9 million related to workforce reductions. We expect to realize approximately $8.0 million to $12.0 million in savings in annual research and development and selling, general and administrative expenses due to the related headcount reductions and facility consolidation activities. These expected savings, however, may be partially offset by product mix changes, potential manufacturing cost increases and other investments in product development during fiscal year 2005 and fiscal year 2006. Consequently, we may not realize an overall decrease in our expenses during fiscal year 2006. Further, as we continue to monitor our operating expenses, facility accruals, divestiture opportunities and space utilizations, we may record additional restructuring charges related to these items. See Note 11 in the Notes to our Consolidated Financial Statements contained in “Item 8 — Financial Statements and Supplementary Data” for further detail.
     During fiscal year 2004, we recorded a net restructuring charge of $6.3 million in operating expenses for facility consolidations primarily in California and Texas, an impairment charge of $1.7 million for property and equipment primarily associated with our Austin, Texas facility consolidation (see “Impairment of Goodwill and Other Intangibles” for further detail) and a net charge of $1.6 million related to workforce reductions. As a result of the outsourcing agreement with ChipPAC, we eliminated 64 of approximately 120 test operation positions in Austin, Texas through March 27, 2004 and recorded a total severance charge of approximately $0.4 million during this fiscal year. Upon completion of the transfer of assets to ChipPAC, we expected to see approximately $6.0 million to $8.0 million in annualized savings that were to begin to be achieved in the second half of fiscal year 2005. Further, we expected to see approximately $4.0 million to $5.0 million in savings in annual research and development expenses due to the non-manufacturing related headcount reductions. As previously disclosed, these expected savings were partially offset by product mix changes, potential manufacturing cost increases and other investments in product development during fiscal year 2005. During fiscal year 2005, we did see a reduction in our annual research and development and selling, general and administrative expenses due to the non-manufacturing related headcount reductions primarily from fiscal year 2004 of approximately $18.4 million.
Page 24 of 71

Table of Contents

     During fiscal year 2003, we recorded a total restructuring charge of $8.6 million, which reflected additional cost reductions that were targeted primarily at further reducing our revenue break-even point. The cost reductions were primarily related to severance and facility consolidations. At the time of this action, we expected a reduction primarily in our research and development and selling, general and administrative costs of approximately $15 million to $20 million. In fiscal year 2004, our combined R&D and SG&A expenses were down by $41.2 million from our fiscal year 2003 levels, specifically $19.1 million in R&D and $22.1 million in SG&A due to our continued cost cutting measures.
     As of March 26, 2005, we have a remaining restructuring accrual for all of our past restructurings of $5.5 million, primarily related to net lease expenses that will be paid over the respective lease terms through fiscal year 2013, along with other anticipated lease termination costs.
Amortization of Acquired Intangibles
     During fiscal year 2005, we recorded $13.7 million in amortization of acquired intangibles related to the fiscal year 2002 acquisitions of LuxSonor, Stream Machine and the assets of Peak Audio, Inc. (“Peak”). The decline from fiscal year 2004 levels is due to the completion of the amortization related to the AudioLogic, Inc. (“AudioLogic”) acquisition. We do not expect to continue to record amortization related to the LuxSonor and Stream Machine acquisitions at the same levels as fiscal year 2005, as these assets will be included in the divestiture of our video product line. When we successfully divest ourselves of the video product line, virtually all of the amortization of acquired intangibles will cease to exist.
     During fiscal year 2004, we recorded $14.4 million in amortization of acquired intangibles related to the fiscal year 2002 acquisitions of LuxSonor, Stream Machine and the assets of Peak, and the fiscal year 2000 acquisition of AudioLogic. The decline from fiscal year 2003 levels was due to the write-off of the intangibles related to the ShareWave, Inc. (“ShareWave”) acquisition. See “Impairment of Goodwill and Other Intangibles” below for a discussion of the impairment of the ShareWave acquired intangibles.
     During fiscal year 2003, we recorded $17.8 million in amortization of acquired intangibles related to the acquisitions of ShareWave, LuxSonor, Stream Machine and the assets of Peak, each in fiscal year 2002 and AudioLogic in fiscal year 2000. See “Impairment of Goodwill and Other Intangibles” below for a discussion of the impairment of the ShareWave acquired intangibles.
Impairment of Goodwill and Other Intangibles
     In accordance with Statement of Financial Accounting Standard No. 131, “Disclosures about Segments of an Enterprise and Related Information,” and Statement of Financial Accounting Standard No. 142 (“SFAS 142”), “Goodwill and Other Intangible Assets,” we consider our business activities to constitute a single operating segment and a single reporting unit, as all operating results are accumulated and reviewed by management at the entity level, which is organized functionally and shares common manufacturing facilities and equipment, common engineering resources and common sales and administrative functions. Accordingly, we assessed goodwill for impairment at an “enterprise” level.
     We performed our SFAS 142 transitional impairment analysis on April 1, 2002, our first business day of our fiscal year 2003. At the time of the transitional impairment test, our market value was $1.6 billion with a book value of $358 million; accordingly, we determined that our goodwill was not impaired.
     At the time of our annual impairment test in early 2003, we estimated the fair value of the Company at $217.7 million and the book value was $309.8 million. Because the book value was more than the fair value, we engaged an independent third party to assist in step two of the goodwill impairment test to measure the amount of an impairment loss. This analysis was based on the residual method, whereby the fair value of the current assets, tangible assets and identified intangible assets are subtracted from the fair value of the Company. The valuation methods used in the independent analysis were the cost approach for the property, plant and equipment and the discounted cash flow method for valuing our technology, customer relationships and trademarks/trade names.
     The non-cash impairment charge to operating expenses to fully impair our goodwill of $126.0 million was primarily driven by the decreased fair value of the Company throughout fiscal year 2003. This was a result of overall economic downturn in the semiconductor industry segment where the Company participates, coupled with the ongoing operating losses and revenue declines of the Company during that period.

     As part of our restructuring activities during the fourth quarter of fiscal year 2003, we closed our wireless product line, acquired in October 2001 in connection with our acquisition of ShareWave and the associated El Dorado Hills, California office. As a result, we recorded a $9.7 million charge in fiscal year 2003 for the entire net book value of the related acquired intangible assets, primarily core technology/patents and one customer agreement. This charge was recorded as a component of impairment of goodwill and other intangibles. The customer agreement terminated during the fourth quarter of fiscal year 2003 and, therefore, had no future value. We are no longer using the technology and associated patents. We were unsuccessful in our efforts to market the technology and associated patents and, therefore, determined their fair value to be zero. As a result of our analysis, we fully impaired the associated acquired intangible assets.
     Due to customer contract negotiations during the fourth quarter of fiscal year 2003, we also reviewed the acquired intangibles pertaining to customer agreements from our fiscal year 2000 acquisition of AudioLogic for potential impairment. As a result, we recorded a $0.5 million charge in fiscal year 2003 for the entire net book value of the customer agreements acquired intangible. This charge was recorded as a component of impairment of goodwill and other intangibles.
     As a result of our fourth quarter fiscal year 2003 restructuring actions, we vacated leased office space at our Austin, Texas facility during the first quarter of fiscal year 2004. As a result of our vacating this leased space, we evaluated our fixed assets on that floor space and determined that an impairment of the existing equipment was necessary and we recorded an impairment charge of $1.5 million during the first quarter of fiscal year 2004 related to this action. Further, during the third quarter of fiscal year 2004, we had a further reduction in headcount worldwide and consolidated office space in our Tokyo, Japan office. As a result of that action, we analyzed our property and equipment at that location and determined that an impairment of our fixed assets had occurred and we recorded an impairment charge of $0.2 million in the fourth quarter of fiscal year 2004 relating to that action.
Lease Termination Costs
     In fiscal year 2003, we bought out a multi-year lease agreement on unused space resulting from our acquisition of Stream Machine in fiscal year 2002 for $7.5 million and recorded a $4.6 million charge. The charge represented the difference between the payment to the landlord and the reversal of the remaining liability recorded in fiscal year 2002 as part of the acquisition.
Patent agreement and settlements, net
     During the third quarter of fiscal year 2005, we released $0.6 million in legal fees originally accrued in connection with the transaction with Broadcom Corporation for certain U.S. and foreign patents. The excess accrual was related to differences from our original estimate and the actual fees incurred related to this transaction.
     On August 11, 2003, we entered into a Patent Sale, Assignment and Cross-License Agreement with NVIDIA and NVIDIA International, Inc. to settle certain pending litigation. As a result of this agreement, NVIDIA paid us $9 million on August 11, 2003. On September 23, 2003, we entered into a Patent Sale, Assignment and Cross-License Agreement with ATI and ATI International SRL to settle certain additional pending litigation. As a result of this agreement, ATI paid us $9 million on October 2, 2003. Under the terms of a contingency fee arrangement, we were obligated to pay outside counsel a percentage of these settlements. During the fourth quarter of fiscal year 2004, we received a net $17 million related to a transaction with Broadcom Corporation for certain U.S. and foreign patents. Both the agreement and settlements were recorded as a separate line item on the statement of operations in operating expenses under the heading “Patent agreement and settlements, net.”
Litigation settlement
     On August 22, 2003, we signed an agreement to settle prior litigation with Western Digital Corporation and its Malaysian subsidiary, Western Digital (M) SDN.BHD, (“WD”). Under the terms of the agreement, WD made a one-time payment to us of $45 million on October 16, 2003. We recorded the settlement as a credit to operating expense during the third quarter of fiscal year 2004 when the payment was received. Part of the $45 million received from WD represented a recovery of bad debt expense recorded in a prior year of approximately $26.5 million.

Realized Gain on Marketable Securities
     During fiscal year 2005, we recognized a gain of $0.8 million related to sale of investments we had in publicly traded companies. In the first quarter of fiscal year 2005, we recognized a gain of $0.7 million on the sale of all of the company’s stock in Silicon Laboratories Inc. (“Silicon Labs”). Total proceeds from the sale were $1.2 million. In the fourth quarter of fiscal year 2005, Cirrus Logic received additional shares in Silicon Labs as a result of a prior merger agreement whereby Silicon Labs acquired Cygnal Integrated Products, Inc. (“Cygnal”). This merger agreement stated that all shareholders in Cygnal, Cirrus Logic included, would receive shares of stock in Silicon Labs in exchange for their shares in Cygnal. Further, the agreement stated that, should Cygnal achieve certain revenue milestones, the former Cygnal shareholders would receive a designated amount of stock in Silicon Labs. Cygnal surpassed certain of those milestones laid out in the merger agreement and, as a result, Silicon Labs distributed certain shares of its stock held in escrow to Cirrus Logic in the fourth quarter of our 2005 fiscal year. Cirrus Logic sold these shares immediately and recognized a gain of $0.1 million.
     In the fourth quarter of fiscal year 2004, we recognized a gain of $2.0 million related to sale of investments we had in other publicly traded companies. During the second quarter of fiscal year 2004, we realized a gain of $10.1 million related to our investment in SigmaTel, Inc. (“SigmaTel”). In November 2000, we entered into a litigation settlement with SigmaTel in which we received shares of common stock, guaranteed to be valued at $10.5 million should SigmaTel complete an initial public offering (“IPO”) in the future. On September 16, 2003, SigmaTel completed their IPO. We sold all of our shares and received $5.6 million, net of selling commissions. We also received a payment of $4.5 million, which was the difference between the guaranteed $10.5 million value and the gross IPO value of our shares.
     During fiscal year 2003, we realized a gain of $1.4 million related to our receipt of the remaining proceeds previously held back by Intel on our fiscal year 2001 sale of our holdings in Basis Communications (“Basis”). This gain was partially offset by a $1.2 million loss realized on our investments in certain public companies due to “other than temporary” declines in the fair value of those investments.
Interest Expense
     Interest expense was $0.2 million in fiscal year 2003. We did not incur any interest expense during fiscal years 2004 or 2005.
Interest Income
     Interest income in fiscal years 2005, 2004, and 2003, was $3.2 million, $1.9 million, and $2.6 million, respectively. The increase in interest income in fiscal year 2005 compared to fiscal year 2004 was primarily due to higher average cash and cash equivalent balances on which interest was earned as well as higher interest rates. Further, during fiscal year 2005 we began implementation of our strategy to utilize longer maturity, higher yield investment instruments. The decrease in interest income in fiscal year 2004 compared with fiscal year 2003 was primarily due to lower average cash and cash equivalent balances on which interest was earned and to lower interest rates.
Other Income (Expense), net
     Other income (expense), net in fiscal year 2005 of $0.3 million consisted primarily of $0.2 million in proceeds from the Chapter 11 bankruptcy distribution by a private company in which we previously held an investment. Other income (expense), net in fiscal year 2003 of $0.4 million consisted primarily of a charge of $0.3 million related to the write-off of an investment in a private company.
Income Taxes
     We recorded an income tax benefit of $20.8 million for fiscal year 2005 on a pre-tax loss of $34.2 million, yielding an effective tax rate of 60.8 percent. This rate differs from the U.S. statutory rate of 35 percent primarily because we were unable to benefit our fiscal year 2005 net operating loss due to the full valuation allowance we continue to have in place on our net deferred tax assets. But, we did record a tax benefit of $21.3 million, representing the reversal of prior year U.S. Federal and foreign tax liabilities. These reversals were due to the expiration of statutes of limitations for the years in which certain potential U.S. and foreign tax liabilities had existed. We also incurred $0.5 million of income taxes that were due in various foreign jurisdictions in which we have offices.
Page 27 of 71

Table of Contents

     We recorded an income tax benefit of $7.1 million for fiscal year 2004 on pre-tax income of $39.4 million, yielding an effective tax benefit rate of 17.9 percent. Our effective tax rate was lower than the U.S. statutory rate of 35 percent primarily because we benefited from the realization of a deferred tax asset related to the Western Digital litigation that had been fully reserved. Our effective tax rate was also impacted by a nonrecurring tax benefit of $7.2 million that was generated by the reversal of prior year state tax liabilities. This reversal was due to the expiration of the statute of limitations for the years in which certain potential state tax liabilities existed. This benefit was partially offset by $0.1 million of income taxes due in certain foreign locations.
     In fiscal year 2003, we recorded an income tax benefit of $3.8 million on a pre-tax loss of $201.6 million, which represents an effective income tax rate of 1.9 percent. The primary reason our benefit was lower than the U.S. statutory rate of 35 percent was that we were not able to fully benefit from our fiscal year 2003 net operating loss due to the full valuation allowance that we have placed on our net deferred tax assets. Our tax benefit included the reversal of $4.0 million of prior year state tax liabilities due to the resolution of a state tax audit. In addition, we received a $0.5 million Federal income tax refund as the result of our ability, under new Federal tax laws, to carry our fiscal year 2002 loss back to fiscal year 1998. These benefits were offset by $0.7 million of income tax expense that consisted of $0.6 million of income taxes due in certain foreign jurisdictions and $0.1 million of foreign taxes withheld on royalty payments from non-U.S. customers.
     In fiscal years 2005, 2004 and 2003, we provided a valuation allowance equal to our net deferred tax assets due to uncertainties regarding whether it is more likely than not that these assets will be realized. We evaluate the realizability of the deferred tax assets on a quarterly basis.
Loss from Discontinued Operations
     During fiscal year 2001, we signed a definitive agreement with Creative Technology Ltd. (“Creative”) and Vertex Technology Fund (II) Ltd., whereby the three companies made investments in eMicro Corporation (“eMicro”), a fabless joint manufacturing venture based in Singapore in which we had a 75 percent interest. We held 12 million shares of preferred stock in this joint venture. There have been no dividends paid from this joint venture. Under the terms of the agreement, eMicro was a licensee of our proprietary ICs and a strategic supplier of audio CODECs and other analog and mixed-signal IC solutions to Creative.
     In April 2002, the eMicro Board of Directors recommended the dissolution of eMicro. In June 2002, the stockholders of eMicro voted to dissolve the joint venture and it ceased operations during the first quarter of fiscal year 2003. eMicro resolved all issues relating to the valuation of its assets and liabilities and the remaining funds were distributed to its shareholders in the first quarter of fiscal year 2004.
     Effective with the first fiscal quarter of 2003, we recorded eMicro’s results of operations as discontinued and reclassified the prior years’ results of operations to discontinued operations for comparative purposes in accordance with SFAS 144.
Outlook
     Our projected outlook for fiscal year 2006 shows improvement over our fiscal year 2005 revenue levels in our mixed-signal, embedded and industrial products. By divesting our video product line and focusing our managerial and financial resources on these core strengths we believe that we will position Cirrus Logic for sustainable profitability and long-term growth. Given current indicators, we expect to drive to operating profitability, exclusive of unforeseen events such as litigation, by achieving revenue growth and continued focus on reducing the cost of our operations. We are committed to becoming a consistently profitable company, which better leverages its engineering and intellectual property resources to achieve growth.
     We are focusing on building a leadership position in our higher-margin audio, analog and mixed-signal product lines. We believe that worldwide adoption of digital audio products, as replacements for outdated analog components, will allow us continued growth opportunities in our audio business. Our expertise in surround-sound audio presents new opportunities beyond the traditional AVR market, as home theater-in-a-box solutions increase. In addition, we have numerous products that support new automotive audio applications and have expanded our opportunities in commercial audio markets, which have accounted for a relatively small percentage of our revenue to date.
     With respect to our video products, on May 24, 2005, we signed a definitive agreement to divest ourselves from this product line during fiscal year 2006. A successful divestiture of this product line will enable us to focus more
Page 28 of 71

sharply on our high-margin analog and mixed-signal and embedded integrated circuit product lines for broad consumer, automotive and industrial market base.
     Overall, we believe that we are well positioned to address the current economic environment, but future revenue, costs, margins, profits and profitability are all influenced by numerous factors, all of which are inherently difficult to forecast. Please refer to “Item 1 – Business” under the subheading “Risk Factors Affecting Our Business and Prospects,” for additional information on these factors. 
Liquidity and Capital Resources
     During fiscal year 2005, we used $17.1 million in cash from operating activities. The use of cash during fiscal year 2005 was primarily driven by our net loss and a decrease in our accounts payable and accrued liabilities of $15.6 million partially offset by the decrease in inventory of $3.0 million and accounts receivable of $1.2 million. We also completed a property lease buyout during the second quarter of fiscal year 2005 totaling $4.3 million for a leased property that we no longer occupied in Broomfield, Colorado, which led to a further reduction of our cash from operating activities. During fiscal year 2004, we generated $69.6 million in cash from operating activities, up from using $18.2 million in cash during fiscal year 2003. The cash generated by operating activities during fiscal year 2004 is primarily related to cash received, net of expenses, upon the successful completion of three litigation settlements totaling $59.4 million (Western Digital Corporation, NVIDIA Corporation and ATI Technologies, Inc.) and the patent agreement with Broadcom Corporation for $17.0 million, net. Also contributing to our cash increase during fiscal year 2004 was an increase in our accounts payable and accrued liabilities of $13.4 million and a slight decrease in our accounts receivable balance. These sources of cash were partially offset by an increase in our inventory balances of $7.3 million. The cash used in operating activities in fiscal year 2003 was a result of the cash components of our net loss and the decline in working capital, partially offset by cash received from a lease settlement. The decline in cash during fiscal year 2003 was primarily driven by the decrease in accounts receivable, as a result of improved collections and lower sales volume, partially offset by a reduction in accounts payable due to lower purchasing volume.
     During fiscal year 2005, we used $65.1 million in cash from investing activities. This use of cash during fiscal year 2005 is primarily due to the purchase of available-for-sale securities of $109.4 million partially offset by the sale of available-for-sale securities of $50.6 million. In addition to the securities, we purchased $6.7 million of property and equipment and technology licenses, including multi-year computer-aided design tool licenses during the fiscal year. We used $25.0 million in cash from investing activities in fiscal year 2004 primarily related to the purchase of marketable securities and the purchase of technology licenses, including multi-year computer-aided design tool licenses and property and equipment. These cash uses were partially offset by the sale of marketable equity securities, the sale of assets related to our manufacturing test operations and a decrease in the level of restricted investments we must maintain. We used $12.4 million in cash from investing activities in fiscal year 2003. This use was primarily attributable to purchases of technology licenses and property and equipment of $21.3 million, partially offset by the receipt of $6.5 million for the LuxSonor escrow claim we made in fiscal year 2002, as well as a decrease in restricted investments of $1.0 million. During the second quarter of fiscal year 2003, we moved within Austin, Texas to our current leased headquarters and engineering facility. In connection with the move, we incurred approximately $11.6 million in capital expenditures.
     During fiscal year 2005 and fiscal year 2004, we generated $3.5 million and $2.3 million, respectively, in cash from financing activities related to the receipt of cash from common stock issuances as a result of the exercises of employee stock options and our employee stock purchase plan. During fiscal year 2003, we generated $1.0 million in cash from financing activities primarily related to the receipt of $1.6 million in cash from common stock issuances as a result of exercises of employee stock options and our employee stock purchase plan, partially offset by $0.6 million in capital lease payments on leases we assumed as a result of our fiscal year 2002 acquisitions.
     As of March 26, 2005, we had restricted investments of $7.9 million, which primarily secures certain obligations under our lease agreement for our principal facility located in Austin, Texas. This facility is 197,000 square feet and houses our headquarters and engineering operations. The operating lease agreement for this facility includes a potential obligation to enter into another lease agreement for a period of 10 years for an additional 64,000 square feet in a new building to be built on property next to our current facility. This obligation is contingent upon construction beginning on the new facility before November 10, 2004. On September 14, 2004, our landlord provided us notice that it had elected to construct the new building. On November 12, 2004, we filed suit against our landlord in the state district court of Travis County, Texas seeking declaratory relief as to our obligations under the current operating lease agreement. Specifically, we seek a declaration that we have no obligation to lease an additional two floors of space because the landlord did not commence construction of the new facility before
Page 29 of 71

Table of Contents

November 10, 2004. In the event that the court determines that the owner of the property has strictly complied with all notices and conditions precedent to entering a new lease, we estimate that the yearly minimum future lease payments could be as much as $1.7 million. In addition, we may be required to provide a cash deposit of $200,000 as well as segregating and restricting an additional $3 million of our available cash balance in the form of a letter of credit. If we are required to enter into a new lease, we are unable to estimate when these potential obligations would begin because it is uncertain when construction will actually be completed.
     Although we cannot assure our stockholders that we will be able to generate cash in the future, we anticipate that our existing capital resources and cash flow generated from future operations will enable us to maintain our current level of operations for at least the next 12 months. 
Off-Balance Sheet Arrangements
     In our business activities, we incur certain commitments to make future payments under contracts such as purchase orders, leases and other long-term contracts. Maturities under these contracts are set forth in the following table as of March 26, 2005:

 	 	Payment due by period (in thousands)

Recently Issued Accounting Pronouncements
     In November 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 151 “Inventory Costs, an amendment of ARB No. 43, Chapter 4” which is effective for fiscal years beginning after June 15, 2005. The pronouncement requires that excessive spoilage, double freight and re-handling costs be recognized as current period charges and that fixed production overhead charges included in the cost of inventory conversion be based upon normal production capacities. This is our current policy and therefore will not affect either our financial condition or the results of operations.
     In December 2004, the FASB issued SFAS No. 123R “Share-Based Payment” which supersedes Accounting Principle Board Opinion (APB) No. 25, “Accounting for Stock Issued to Employees,” SFAS No. 123, “Accounting for Stock Based Compensation,” and related implementation guidance. Under this pronouncement, stock based compensation to employees is required to be recognized as a charge to the statement of operations and such charge is to be measured according to the fair value of the stock options. In the absence of an observable market price for the stock awards, the fair value of the stock options would be based upon a valuation methodology that takes into consideration various factors, including the exercise price of the option, the expected term of the option, the current price of the underlying shares, the volatility of the company’s stock and the risk free interest rate. Our current policy is not to expense share based compensation; however, we do disclose the affect of this item as currently required by SFAS 123. SFAS No. 123R allows for either prospective recognition of compensation expense or retrospective recognition, which may be back to the original issuance of SFAS No. 123 or only to interim periods in the year of adoption. The company is currently evaluating these transition methods and the impact this pronouncement will have on us. The pronouncement will now be effective for fiscal years beginning after June 15, 2005. For Cirrus Logic, we will adopt this pronouncement beginning in fiscal year 2007, which begins March 26, 2006.
Critical Accounting Policies
     Our discussion and analysis of the Company’s financial condition and results of operations are based upon the consolidated financial statements included in this report, which have been prepared in accordance with U. S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts. We evaluate the estimates on an on-going basis. We base these estimates on historical experience and on various other assumptions that we believe to be reasonable under the
Page 30 of 71

Table of Contents

circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions and conditions. We also have policies that we consider to be key accounting policies, such as our policies for revenue recognition, including the deferral of revenues and gross profit on sales to our 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.
     We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of the consolidated financial statements:

§   	We maintain allowances for doubtful accounts for estimated losses resulting from the inability or failure of our customers to make required payments. We regularly evaluate our allowance for doubtful accounts based upon the age of the receivable, our ongoing customer relations, as well as any disputes with the customer. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required, which could have a material effect on our operating results and financial position. Additionally, we may maintain an allowance for doubtful accounts for estimated losses on receivables from customers with whom we are involved in litigation. See Note 4 in the Notes to our Consolidated Financial Statements contained in “Item 8 – Financial Statements and Supplementary Data.”	

§   	Inventories are recorded at the lower of cost or market, with cost being determined on a first-in, first-out basis. We write down inventories to net realizable value based on forecasted demand, management judgment and the age of inventory. Actual demand and market conditions may be different from those projected by management, which could have a material effect on our operating results and financial position.	

§   	We evaluate the recoverability of property and equipment and intangible assets in accordance with Statement of Financial Accounting Standard No. 144 (“SFAS 144”), “Accounting for the Impairment or Disposal of Long-Lived Assets.” We test for impairment losses on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts. An impairment loss is recognized in the event the carrying value of these assets exceeds the fair value of the applicable assets. Impairment evaluations involve management estimates of asset useful lives and future cash flows. Actual useful lives and cash flows could be different from those estimated by management, which could have a material effect on our operating results and financial position. See Note 5 in the Notes to our Consolidated Financial Statements contained in “Item 8 – Financial Statements and Supplementary Data.”	

§   	Restructuring charges for workforce reductions and facilities consolidations reflected in the accompanying financial statements were accrued based upon specific plans established by management, in accordance with Emerging Issues Task Force No. 94-3 (“EITF 94-3”), “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)” or SFAS 146, “ Accounting for Costs Associated with Exit or Disposal Activities ” depending upon the time of the restructuring activity. We use an estimated borrowing rate as the discount rate for all of our restructuring accruals made under SFAS 146. Our facilities consolidation accruals were based upon our estimates as to the length of time a facility would be vacant, as well as the amount of sublease income we would receive once we sublet the facility, after considering current and projected market conditions. Changes in these estimates could result in an adjustment to our restructuring accruals in a future quarter, which could have a material effect on our operating results and financial position. See Note 11 in the Notes to our Consolidated Financial Statements contained in “Item 8 – Financial Statements and Supplementary Data.”	

§   	Our taxes payable balance is comprised primarily of tax contingencies that are recorded to address exposures involving tax positions we have taken that could be challenged by taxing authorities. These exposures result from the varying application of statutes, rules, regulations and interpretations. Our tax contingencies are established based on past experiences and judgments about potential actions by taxing jurisdictions. Our tax contingencies relate, in large part, to transfer pricing positions we have taken in a variety of countries in which we operate. We have also accrued tax contingencies for certain domestic tax matters. The ultimate resolution of these matters may be materially greater or less than the amount that we have accrued.	

§   	We are subject to the possibility of loss contingencies for various legal matters. See Note 8 in the Notes to our Consolidated Financial Statements contained in “ Item 8 – Financial Statements and Supplementary Data.” We regularly evaluate current information available to us to determine whether any accruals should be made based on the status of the case, the results of the discovery process and other factors. If we ultimately determine that an accrual should be made for a legal matter, this accrual could have a material effect on our operating results and financial position and the ultimate outcome may be materially different than our estimate.

ITEM 7A. Quantitative and Qualitative Disclosures about Market Risk
     We are exposed to market risks associated with interest rates on our debt securities and currency movements on non-U.S. dollar denominated assets and liabilities. We assess these risks on a regular basis and have established policies to protect against the adverse effects of these and other potential exposures. All of the potential changes noted below are based on sensitivity analyses at March 26, 2005. Actual results may differ materially.
Interest Rate Risk
     At March 26, 2005, an immediate one percent, or 100 basis points, increase or decrease could result in a $1.9 million fluctuation in our annual interest income. We believe the risks associated with fluctuating interest rates are limited to our annual interest income and not the underlying principal as we generally have the ability to hold the debt related investments to maturity. Cirrus Logic is debt free, therefore a change in interest rates is unlikely to have a material impact on interest expense. During fiscal year 2004, our exposure to interest rate risk was minimal due to our investment portfolio, which was primarily in risk-free accounts.
Foreign Currency Exchange Risk
     Our revenue and spending is transacted primarily in U.S. dollars; however, in fiscal years 2005, 2004 and 2003, we entered into minimal transactions in other currencies to fund the operating needs of our design, technical support and sales offices outside of the U.S. As of March 26, 2005 and March 27, 2004, a ten percent change in the value of the related currencies would not have a material impact on our results of operations and financial position.
     In addition to the direct effects of changes in exchange rates on the value of open exchange contracts we may have from time to time, changes in exchange rates can also affect the volume of sales or the foreign currency sales prices of our products and the relative costs of operations based overseas.

Report of Independent Registered Public Accounting Firm
The Board of Directors and Shareholders of Cirrus Logic, Inc.
We have audited the accompanying consolidated balance sheets of Cirrus Logic, Inc as of March 26, 2005 and March 27, 2004, and the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for each of the three fiscal years in the period ended March 26, 2005. 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 Cirrus Logic, Inc. as of March 26, 2005 and March 27, 2004, and the consolidated results of its operations and its cash flows for each of the three fiscal years in the period ended March 26, 2005, 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), the effectiveness of Cirrus Logic Inc.’s internal control over financial reporting as of March 26, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 26, 2005 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm
On Internal Control over Financial Reporting
The Board of Directors and Shareholders of Cirrus Logic, Inc.
We have audited management’s assessment, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting, that Cirrus Logic, Inc. maintained effective internal control over financial reporting as of March 26, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Cirrus Logic, 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. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of 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, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, 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, management’s assessment that Cirrus Logic, Inc. maintained effective internal control over financial reporting as of March 26, 2005, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, Cirrus Logic, Inc. maintained, in all material respects, effective internal control over financial reporting as of March 26, 2005, 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 Cirrus Logic, Inc. as of March 26, 2005 and March 27, 2004, and the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for each of the three fiscal years in the period ended March 26, 2005 of Cirrus Logic, Inc. and our report dated May 26, 2005 expressed an unqualified opinion thereon.

CIRRUS LOGIC, INC .
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Description of Business and Summary of Significant Accounting Policies
Description of Business
     Cirrus Logic (“we,” “us,” “our,” or the “Company”) is a premier supplier of high-precision analog and mixed-signal integrated circuits (“ICs”) for a broad range of consumer and industrial markets. We develop and market integrated ICs and embedded software used by original equipment manufacturers (“OEMs”). We also provide complete system reference designs based on our technology that enable our customers to bring products to market in a timely and cost-effective manner.
     We were founded in 1984 and were reincorporated in the State of Delaware in February 1999. Our headquarters are in Austin, Texas and we have a major site in Boulder, Colorado. We also serve customers from international offices in Europe and Asia, including the People’s Republic of China, Korea, Japan, Singapore and Taiwan. Our common stock, which has been publicly traded since 1989, is listed on the NASDAQ National Market under the symbol CRUS.
Basis of Presentation
     We prepare financial statements on a 52- or 53-week year that ends on the last Saturday in March. All fiscal years presented include 52 weeks.
Principles of Consolidation
     The accompanying consolidated financial statements have been prepared in accordance with U. S. generally accepted accounting principles and include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
Use of Estimates
     The preparation of financial statements in accordance with U. S. generally accepted accounting principles require the use of management estimates. These estimates are subjective in nature and involve judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at fiscal year end and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.
Reclassifications
     Certain reclassifications have been made to conform to the fiscal year 2005 presentation. These reclassifications had no effect on the results of operations or stockholders’ equity.
Cash and Cash Equivalents
     Cash and cash equivalents consist primarily of money market funds, commercial paper, U.S. Government Treasury and Agency instruments with original maturities of three months or less at the date of purchase.
Marketable Securities and Restricted Investments
     We determine the appropriate classification of marketable securities at the time of purchase and reevaluate such designation as of each balance sheet date. We classify these securities as either held-to-maturity, trading, or available-for-sale in accordance with Statement of Financial Accounting Standards No. 115 (“SFAS 115”), “ Accounting for Certain Investments in Debt and Equity Securities .” As of March 26, 2005 and March 27, 2004, all marketable securities and restricted investments were classified as available-for-sale securities.
     Available-for-sale securities are carried at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive income (loss). The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion of discounts to maturity computed under the effective interest

method, and is included in interest income. Realized gains and losses, declines in value judged to be other than temporary and interest on available-for-sale securities are included in net income. The cost of securities sold is based on the specific identification method.
Inventories
     We use the lower of cost or market method to value our inventories, with cost being determined on a first-in, first-out basis. One of the factors we consistently evaluate in the application of this method is the extent to which products are accepted into the marketplace. By policy, we evaluate market acceptance based on known business factors and conditions by comparing forecasted customer unit demand for our products over a specific future period, or demand horizon, to quantities on hand at the end of each accounting period.
     On a quarterly and annual basis, we analyze inventories on a part-by-part basis. Inventory quantities on hand in excess of forecasted demand are considered to have reduced market value and, therefore, the cost basis is adjusted to the lower of cost or market. Typically, market values for excess or obsolete inventories are considered to be zero. The short product life cycles and the competitive nature of the industry are factors considered in the estimation of customer unit demand at the end of each quarterly accounting period.
     Inventories were comprised of the following (in thousands): 

 	 	March 26,	 	 	March 27,	 	
 	 	2005	 	 	2004	 	
Work in process	 	$	20,142	 	 	$	17,178

Inventories	 	$	26,649	 	 	$	29,632	 	
 	 	 	 	 	 	 	
Assets Held for Sale
     On June 26, 2003, we agreed to sell our test operation assets for $3.5 million, which consist primarily of analog and mixed-signal testers, handlers and wafer probes, to ChipPAC, Inc. (“ChipPAC”), a provider of semiconductor packaging design, assembly, test and distribution services. The transaction closed and the cash was received on June 30, 2003. As a result of the planned transfer of these assets to ChipPAC, we recorded an impairment charge of $0.7 million in cost of sales during the first quarter of fiscal year 2004 and reclassified the related assets to assets held for sale, a component of other current assets. On March 27, 2004, we had $2.5 million in assets held for sale and $2.5 million in accrued liabilities related to proceeds received in advance of the assets being transferred. We completed the transfer of assets during December 2004, and therefore, we no longer reflect the assets or liabilities on the balance sheet.
Property and Equipment, net
     Property and equipment is recorded at cost, net of depreciation and amortization. Depreciation and amortization is calculated on a straight-line basis over estimated economic lives, ranging from three to ten years. Leasehold improvements are depreciated over the shorter of the term of the lease or the estimated useful life. Gains or losses related to retirements or dispositions of fixed assets are recognized in the period incurred.
     Property and equipment was comprised of the following (in thousands): 

 	 	March 26,	 	 	March 27,	 	
 	 	2005	 	 	2004	 	
Furniture and fixtures	 	$	5,399	 	 	$	14,897	 	
Leasehold improvements	 	 	15,388	 	 	 	21,262	 	
Machinery and equipment	 	 	26,246	 	 	 	92,038	 	
Capitalized software	 	 	18,348	 	 	 	33,200	 	
 	 	 	 	 	 	 	
Total property and equipment	 	 	65,381	 	 	 	161,397	 	
Less: Accumulated depreciation and amortization	 	 	(47,809	)	 	 	(138,734	)	
 	 	 	 	 	 	 	
Property and equipment, net	 	$	17,572	 	 	$	22,663	 	
 	 	 	 	 	 	 	
     Depreciation and amortization expense on property and equipment for fiscal years 2005, 2004, and 2003 was $7.1 million, $8.9 million, and $14.9 million, respectively.
     As a result of our fourth quarter fiscal year 2003 restructuring actions, we vacated leased office space at our Austin, Texas facility during the first quarter of fiscal year 2004. As a result of our vacating this leased space, we evaluated our fixed assets on that floor space and determined that an impairment of the existing equipment was
Page 40 of 71

Table of Contents

necessary. The amounts were determined based upon market prices for similar assets and we recorded an impairment charge to “restructuring and other costs” for $1.5 million during the first quarter of fiscal year 2004 related to this action. Further, during the third quarter of fiscal year 2004, we had a further reduction in headcount worldwide and consolidated office space in our Tokyo, Japan office. As a result of that action, we analyzed our property and equipment at that location, based on values of similar assets and determined that an impairment of our fixed assets had occurred and we recorded an impairment charge to “restructuring and other costs” for $0.2 million in the fourth quarter relating to that action.
     In fiscal year 2004, as a result of our outsourcing agreement with ChipPAC, we reclassified $48.0 million of gross assets with a net book value of $4.2 million as assets held for sale. During fiscal year 2005 and 2004, as a result of an ongoing detailed analysis of our fixed assets, we retired $75.8 million and $62.7 million, respectively, of fully depreciated assets that were no longer in service. We also transferred, as part of our continued outsourcing agreement, approximately $20.2 million of gross fixed assets related to the asset sales to Amkor Technology (“Amkor”) and Premier Semiconductor Services (“Premier”) during the fourth quarter of fiscal year 2005. These assets were sold to their respective parties in two separate transactions. The first transaction, the Amkor asset sale, resulted in a gain, recorded as a component in cost of sales, of $0.1 million on $0.8 million worth of net book value of machinery and equipment. The second transaction, the Premier asset sale, resulted in a gain of $0.1 million, recorded as a component in cost of sales, on $0.1 million worth of net machinery and equipment.
Intangibles, Net
     Intangible assets include purchased technology licenses that are recorded at cost and are generally amortized on a straight-line basis over their useful lives, ranging from three to five years. Acquired intangibles, recorded in connection with our acquisitions, include existing technology, core technology/patents, license agreements, trademarks, covenants not-to-compete and customer agreements. These assets are amortized on a straight-line basis over lives ranging from one to nine years.
Long-lived assets
     In accordance with Statement of Financial Accounting Standard No. 144 (“SFAS 144”), “ Accounting for the Impairment or Disposal of Long-Lived Assets,” we test for impairment losses on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts. We measure any impairment loss by comparing the fair value of the asset to its carrying amount. We estimate fair value based on discounted future cash flows, quoted market prices, or independent appraisals.
Goodwill
     In June 2001, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard No. 142 (“SFAS 142”) “Goodwill and Other Intangible Assets,” Under SFAS 142, goodwill and intangible assets with indefinite lives are no longer amortized but are tested annually (or more frequently if impairment indicators arise) for impairment. We applied the provisions of SFAS 142 to goodwill and intangible assets from business combinations initiated after June 30, 2001. We adopted the remaining provisions of SFAS 142 on March 31, 2002, the first day of fiscal year 2003. Accordingly, we did not record goodwill amortization expense in fiscal years 2005, 2004, or 2003. We performed both our required transitional goodwill impairment test as well as our annual goodwill impairment test during fiscal year 2003, which resulted in a goodwill impairment charge of $126.0 million. During fiscal years 2004 and 2005, we did not perform a SFAS 142 analysis, as we did not have any goodwill or other indefinite lived assets.
Foreign Currency Translation
     All of our international subsidiaries have the U.S. dollar as the functional currency. The local currency financial statements are remeasured into U.S. dollars using current rates of exchange for assets and liabilities. Gains and losses from remeasurement are included in other income (expense), net. Revenue and expenses from our international subsidiaries are translated using the monthly average exchange rates in effect for the period in which the items occur. For all periods presented, our foreign currency translation expense was immaterial.

Credit Risk Concentration
     Financial instruments that potentially subject us to material concentrations of credit risk consist primarily of cash equivalents, restricted investments, marketable securities, long-term marketable securities and trade accounts receivable. We are exposed to credit risk to the extent of the amounts recorded on the balance sheet. By policy, our cash equivalents, restricted investments, marketable securities and long-term marketable securities are subject to certain nationally recognized credit standards, issuer concentrations, sovereign risk and marketability or liquidity considerations.
     In evaluating our trade receivables, we perform credit evaluations of our major customers’ financial condition and monitor closely all of our receivables to limit our financial exposure by limiting the length of time and amount of credit extended. We sell a significant amount of products in the Asia countries. In certain situations, we may require payment in advance or utilize letters of credit to reduce credit risk. By policy, we establish a reserve for trade accounts receivable based on the type of business in which a customer is engaged, the length of time a trade account receivable is outstanding and other knowledge that we may possess relating to the probability that a trade receivable is at risk for non-payment.
     The following table summarizes customers whose receivable balances represent more than 10 percent of consolidated gross short-term accounts receivable: 

 	 	March 26,	 	 	March 27,	 	
 	 	2005	 	 	2004	 	
Memec Group Holdings Limited	 	 	35	%	 	 	33	%	
L.G. Group	 	 	10	%	 	 	—	 	
     The following table summarizes sales to distributor (Memec Holdings Group) and other customers that represent more than 10 percent of our consolidated net sales: 

 	 	March 26,	 	 	March 27,	 	 	March 29,	 	
 	 	2005	 	 	2004	 	 	2003	 	
Memec Holdings Group	 	 	27	%	 	 	20	%	 	 	15	%	
Thomson S.A.	 	 	—	 	 	 	—	 	 	 	12	%	
     No other customers or distributors accounted for 10 percent or more of net sales in fiscal years 2005, 2004, and 2003. The loss of a significant customer or distributor or a significant reduction in a customers or distributors orders could have an adverse effect on our sales. Our sales to Thomson S.A. primarily consisted of DVD drive manager devices that were included in game console products. These sales were made under a volume purchase agreement, the delivery terms of which have been fulfilled.
Revenue Recognition
     We recognize revenue in accordance with the Securities and Exchange Commission’s Staff Accounting Bulletin No. 104 (“SAB 104”), “ Revenue Recognition.” Revenue from product sold directly to customers and to certain international distributors is recognized upon title passage of inventory. For sales made directly to domestic customers, title generally passes upon shipment. For sales made directly to international customers and to certain international distributors, title generally passes at the port of destination, which coincides with delivery to the international distributors. Sales made to domestic distributors and certain international distributors are recorded as deferred revenue until the final sale to the end customer has occurred as the distributor agreements allow certain rights of return, price adjustments and price protection. License and royalty revenue is recognized as it is earned per unit shipped or when a milestone is reached.
Warranty Expense
     In November 2002, the FASB issued Interpretation No. 45 (“FIN 45”), “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.” Currently, the only applicable item of FIN 45 relates to the impact of paragraph 14, which refers to product warranties. Because we do not have extended warranties, our exposure is limited to product returns for defective products. In general, we warrant that the products, when delivered, will be free from defects in material workmanship under normal use and service. Our obligations are limited to replacing, repairing or giving credit for, at our option, any products that are returned within one year after the date of shipment and if notice is given to us in writing within 30 days of the customer learning of such problem. Warranty expense was not significant for any period presented.

Shipping Costs
     Our shipping and handling costs are included in cost of sales for all periods presented.
Advertising Costs
     Advertising costs are expensed as incurred. Advertising costs were $1.7 million, $1.5 million, and $1.9 million, in fiscal years 2005, 2004, and 2003, respectively.
Stock-Based Compensation
     The FASB issued SFAS No. 123R “ Share-Based Payment” which supersedes Accounting Principles Board Opinion No. 25 (“APB 25”), “Accounting for Stock Issued to Employees,” SFAS No. 123, “Accounting for Stock-Based Compensation” and related implementation guidance. The pronouncement is effective for annual periods beginning after June 15, 2005, and we will implement it at that time. Refer to the section titled “ Recently Issued Accounting Pronouncements” for a more detailed discussion of the specific requirements.
     We apply the intrinsic value method in accounting for our stock option and stock purchase plans in accordance with APB 25, “Accounting for Stock Issued to Employees.” Accordingly, no compensation cost has been recognized for options granted with an exercise price equal to market value at the date of grant or in connection with the employee stock purchase plan. In December 2002, the FASB issued Statement of Financial Accounting Standard No. 148 (“SFAS 148”), “Accounting for Stock-Based Compensation – Transition and Disclosure,” which currently affects us only with regard to quarterly and annual reporting of the pro forma effect on net income and earnings per share of applying the Black-Scholes method to measure compensation expense as required under Statement of Financial Accounting Standard No. 123, “Accounting for Stock-Based Compensation.”
     The following table details the disclosure required by SFAS 123 (in thousands, except per share amounts):

Pro forma diluted net income (loss) per share	 	 	(0.29	)	 	 	0.39	 	 	 	(2.54	)	
Income Taxes
     We account for income taxes in accordance with Statement of Financial Accounting Standard No. 109 (“SFAS 109”), “Accounting for Income Taxes,” which provides for the recognition of deferred tax assets if realization of such assets is more likely than not. We have provided a valuation allowance equal to our net deferred tax assets due to uncertainties regarding their realization. We evaluate the realizability of our deferred tax assets on a quarterly basis.
Net Income (Loss) Per Share
     Basic net income (loss) per share is based on the weighted effect of common shares issued and outstanding and is calculated by dividing net income (loss) by the basic weighted average shares outstanding during the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of common shares used in the basic net income (loss) per share calculation, plus the number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding.
     Incremental weighted average common shares attributable to the assumed exercise of outstanding options of 1,510,000 and 538,000 shares for the years ended March 26, 2005 and March 29, 2003, respectively, were excluded from the computation of diluted net income (loss) per share because the effect would be anti-dilutive due to our loss position during fiscal years 2005 and 2003. The weighted outstanding options excluded from our diluted calculation

for the years ended March 26, 2005, March 27, 2004, and March 29, 2003 were 7,501,000, 6,729,000, and 10,755,000, respectively, as the exercise price exceeded the average market price during the period.
Accumulated Other Comprehensive Loss
     We report our accumulated other comprehensive income (loss) based upon Statement of Financial Accounting Standard No. 130, “ Reporting Comprehensive Income .” Our accumulated other comprehensive loss is comprised of foreign currency translation adjustments and unrealized gains and losses on investments classified as available-for-sale.
Recently Issued Accounting Pronouncements
     In November 2004, the FASB issued Statement of Financial Accounting Standards No. 151 “Inventory Costs, an amendment of ARB No. 43, Chapter 4” which is effective for fiscal years beginning after June 15, 2005. The pronouncement requires that excessive spoilage, double freight and re-handling costs be recognized as current period charges and that fixed production overhead charges included in the cost of inventory conversion be based upon normal production capacities. This is our current policy and therefore adoption of this standard will not affect either our financial condition or the results of operations.
     In December 2004, the FASB issued SFAS No. 123R “Share-Based Payment” which supersedes APB 25, “Accounting for Stock Issued to Employees,” SFAS No. 123, “Accounting for Stock Based Compensation,” and related implementation guidance. Under this pronouncement, stock based compensation to employees is required to be recognized as a charge to the statement of operations and such charge is to be measured according to the fair value of the stock options. In the absence of an observable market price for the stock awards, the fair value of the stock options would be based upon a valuation methodology that takes into consideration various factors, including the exercise price of the option, the expected life of the option, the current price of the underlying shares, the volatility of the company’s stock and the risk free interest rate. Our current policy is not to expense share based compensation; however, we do disclose the affect of this item as currently required by SFAS 123. SFAS No. 123R allows for either prospective recognition of compensation expense or retrospective recognition, which may be back to the original issuance of SFAS No. 123 or only to interim periods in the year of adoption. The company is currently evaluating these transition methods and the impact this pronouncement will have on us. The pronouncement is effective for fiscal years beginning after June 15, 2005. For Cirrus Logic, we will adopt this pronouncement beginning in fiscal year 2007, which begins March 26, 2006.
Fair Value of Financial Instruments
     The Company’s financial instruments consist principally of cash and cash equivalents, investments, receivables and accounts payable. The Company believes all of these financial instruments are recorded at amounts that approximate their current market values due to their short-term nature or because they are stated at fair value.
2. Restricted Investments
     As of March 26, 2005 and March 27, 2004, we have restricted investments of $7.9 million and $8.2 million, respectively, in support of our letter of credit needs. The letters of credit primarily secure certain obligations under our operating lease agreement for our headquarters and engineering facility in Austin, Texas. This secured amount declines over our lease term through fiscal year 2013.

3. Marketable Securities
     The Company’s investments that have original maturities greater than ninety days have been classified as available-for-sale securities in accordance with Statement of Financial Accounting Standards No. 115 (“SFAS 115”), “Accounting for Certain Investments in Debt and Equity Securities.” Marketable securities are categorized on the Balance Sheet as Restricted investments, Marketable securities and Long-term marketable securities, as appropriate.
     The following table is a summary of available-for-sale securities (in thousands):

     During fiscal year 2005, we recognized a gain of $0.8 million related to sale of investments we had in publicly traded companies. In the first quarter of fiscal year 2005, we recognized a gain of $0.7 million on the sale of all of the Company’s stock in Silicon Laboratories Inc. (“Silicon Labs”). Total proceeds from the sale were $1.2 million. In the fourth quarter of fiscal year 2005, Cirrus Logic received additional shares in Silicon Labs as a result of a prior merger agreement whereby Silicon Labs acquired Cygnal Integrated Products, Inc. (“Cygnal”). This merger agreement stated that all shareholders in Cygnal, Cirrus Logic included, would receive shares of stock in Silicon Labs in exchange for their shares in Cygnal. Further, the agreement stated that, should Cygnal achieve certain revenue milestones, the former Cygnal shareholders would receive a designated amount of stock in Silicon Labs. Cygnal surpassed certain of those milestones laid out in the merger agreement and, as a result, Silicon Labs distributed certain shares of its stock held in escrow to Cirrus Logic in the fourth quarter of our 2005 fiscal year. Cirrus Logic sold these shares immediately and recognized a gain of $0.1 million. The unrealized losses on our available-for-sale securities currently held that were recorded in fiscal year 2005 and the unrealized gains reported in fiscal year 2004 on our available-for-sale securities were temporary in nature, as our investing policy allows us to change our investment strategy based upon the yield on alternative investments or a need for liquidity.

     In fiscal year 2004, we recognized a gain of $12.1 million related to sale of investments we had in other publicly traded companies. This was related primarily to a realized gain of $10.1 million on our investment in SigmaTel, Inc. (“SigmaTel”). In November 2000, we entered into a litigation settlement with SigmaTel in which we received shares of common stock, guaranteed to be valued at $10.5 million should SigmaTel complete an initial public offering (“IPO”) in the future. On September 16, 2003, SigmaTel completed their IPO. We sold all of our shares and received $5.6 million, net of selling commissions. We also received a payment of $4.5 million, which was the difference between the guaranteed $10.5 million value and the gross IPO value of our shares.

     We were successful in collecting the Western Digital receivable during fiscal year 2004 and we recorded a credit to operating expenses of $45 million as our litigation settlement of which, $26.5 million was a recovery of bad debt previously recorded in a prior fiscal year. The Fujitsu receivable and the related allowance, of $46.8 million is fully reserved. See Note 8 and Note 19 for further discussion of the litigation with Fujitsu and Note 9 for further discussion regarding the settlement with Western Digital.

     In connection with our headcount reductions in fiscal year 2005 (see Note 11 for further detail), we recorded an impairment charge of $5.0 million for the abandonment of certain computer aided design (“CAD”) and other software tools that will no longer be utilized. The assets were a component of the “Technology Licenses” group in the above table. Amortization expense for all intangibles in fiscal years 2005, 2004, and 2003 was $17.1 million, $18.3 million, and $25.1 million, respectively.

     In accordance with SFAS 131, “ Disclosures about Segments of an Enterprise and Related Information .” and SFAS 142 “Goodwill and Other Intangible Assets,” we consider our business activities to constitute a single operating segment and a single reporting unit, as all operating results are accumulated and reviewed by management at the entity level, which is organized functionally and shares common manufacturing facilities and equipment, common engineering resources and common administrative, accounting and IT functions. Accordingly, we assessed goodwill for impairment at an “enterprise” level.
     We performed our SFAS 142 transitional impairment analysis on April 1, 2002, our first business day of our fiscal year 2003. At the time of the transitional impairment test, our market value was $1.6 billion with a book value of $358 million; accordingly, we determined that our goodwill was not impaired. At the time of our annual impairment test in early 2003, we estimated the fair value of the Company at $217.7 million and the book value was $309.8 million. Because the book value was more than the fair value, we engaged an independent third party to assist in step two of the goodwill impairment test to measure the amount of an impairment loss. This analysis was based on the residual method, whereby the fair value of the current assets, tangible assets and identified intangible assets are subtracted from the fair value of the Company. The valuation methods used in the independent analysis were the cost approach for the property, plant and equipment and the discounted cash flow method for valuing our technology, customer relationships and trademarks/trade names. The non-cash impairment charge to operating expenses to fully impair our goodwill of $126.0 million recorded under “Impairment of goodwill and other intangibles,” was primarily driven by the decreased fair value of the Company throughout fiscal year 2003. This was a result of overall economic downturn in the semiconductor industry segment where the Company participates, coupled with the ongoing operating losses and revenue declines of the Company during that period.
     As part of our restructuring activities during the fourth quarter of fiscal year 2003, we closed our wireless product line, acquired in October 2001 in connection with our acquisition of ShareWave, and the associated El Dorado Hills, California office. As a result, we recorded a $9.7 million charge in fiscal year 2003 for the entire net book value of the related acquired intangible assets, primarily core technology/patents and one customer agreement. This charge was recorded as a component of “Impairment of goodwill and other intangibles.” The customer agreement terminated during the fourth quarter of fiscal year 2003 and, therefore, had no future value. We are no longer using the technology and associated patents. We were unsuccessful in our efforts to market the technology and associated patents and, therefore, determined their fair value to be zero. As a result of our analysis, we fully impaired the associated acquired intangible assets.
     Due to customer contract negotiations during the fourth quarter of fiscal year 2003, we also reviewed the acquired intangibles pertaining to customer agreements from our fiscal year 2000 acquisition of AudioLogic, Inc. for potential impairment. As a result, we recorded a $0.5 million charge in fiscal year 2003 for the entire net book value of the customer agreements acquired intangible. This charge was recorded as a component of impairment of goodwill and other intangibles. During fiscal year 2004, we subsequently wrote off the fully amortized existing technology associated with this acquisition for a total of $6.4 million.
6. Discontinued Operations – eMicro Joint Venture
     During fiscal year 2001, we signed a definitive agreement with Creative Technology Ltd. (“Creative”) and Vertex Technology Fund (II) Ltd., whereby the three companies made investments in eMicro Corporation (“eMicro”), a fabless joint manufacturing venture based in Singapore in which we had a 75 percent interest. We held 12 million shares of preferred stock in this joint venture. There have been no dividends paid from this joint venture. Under the terms of the agreement, eMicro was a licensee of our proprietary ICs and a strategic supplier of audio CODECs and other mixed-signal IC solutions to Creative.
     In April 2002, the eMicro Board of Directors recommended the dissolution of eMicro. In June 2002, the stockholders of eMicro voted to dissolve the joint venture and it ceased operations during the first quarter of fiscal year 2003. eMicro resolved all issues relating to the valuation of its assets and liabilities and, therefore, distributed the remaining funds owed to its shareholders during fiscal year 2004. The amount recorded as foreign currency translation expense related to the dissolution of our investment in eMicro was $49 thousand.
     Effective with the first fiscal quarter of 2003, we recorded eMicro’s results of operations as discontinued in accordance with SFAS 144. eMicro’s revenue and operating loss included in discontinued operations for fiscal year 2003 were $0.9 million and $2.0 million, respectively.

7. Commitments and Contingencies
Facilities and Equipment Under Operating Lease Agreements
     We lease our facilities and certain equipment under operating lease agreements, some of which have renewal options. Certain of these arrangements provide for lease payment increases based upon future fair market rates. Our principal facilities, located in Austin, Texas, consists of approximately 251,000 square feet of leased office and test space, which have leases that expire from 2005 to 2012, excluding renewal options. This space is used for product development and testing, sales, marketing and administration. It includes our headquarters and engineering facility, which has 197,000 square feet and no escalating rent clauses. We have an obligation to lease additional space in a new building next to our current facility, should construction of this building begin before November 10, 2004. The lease agreement for this facility includes a potential obligation to enter into another lease agreement for a period of 10 years for an additional 64,000 square feet in a new building to be built on property next to our current facility. This obligation was contingent upon construction beginning on the new facility before November 10, 2004. On September 14, 2004, our landlord provided us notice that it had elected to construct the new building. However, as of May 27, 2005, actual construction on the new building had not commenced. In the event that the court determines that the owner of the property has strictly complied with all notices and conditions precedent to entering a new lease, we estimate that the yearly minimum future lease payments could be as much as $1.7 million, which has not been included in the table below. In addition, we may be required to provide a cash deposit of $200,000 as well as segregating and restricting an additional $3 million of our available cash balance in the form of a letter of credit. If we are required to enter into a new lease, we are unable to estimate when these potential obligations would begin because it is uncertain when construction will actually be completed.. See Note 8, “ Legal Proceedings - Facilities Under Operating Lease Agreements” for more information regarding this potential lease obligation.

     Total rent expense was approximately $11.5 million, $13.9 million, and $13.6 million, for fiscal years 2005, 2004, and 2003, respectively. Sublease rental income was $5.8 million, $5.4 million, and $6.3 million, for fiscal years 2005, 2004, and 2003, respectively. The sublease commitment information shown above for future years does not include the $7.4 million settlement we received in fiscal year 2003 when one of our California tenants exited their subleases for approximately 145,000 square feet. This amount is being amortized on a straight-line basis as a reduction in operating expenses over the remaining lease periods with a total remaining balance at March 26, 2005 of $4.1 million. Further, we recorded a charge to operating expense during fiscal year 2004 in the amount of $0.4 million for the Raleigh, North Carolina facility and $1.4 million for our Fremont, California facility. The amounts were determined when a tenant broke their sublease with us in our Raleigh, North Carolina property and we determined we would be unable to sublease our Fremont, California property as quickly as previously expected due to the depressed commercial real estate market in the area. As of March 26, 2005, a total of $1.6 million related to these vacated leases remained accrued. These amounts are classified as either long-term or short-term; where appropriate. These amounts are included in the table above, as well as the $5.5 million of accrued restructuring facility costs that are discussed in greater detail in Note 11.
Wafer, Assembly and Test Purchase Commitments
     We rely on third-party foundries for our wafer manufacturing needs. As of March 26, 2005, we had agreements with multiple foundries for the manufacture of wafers. None of these agreements has volume purchase commitments or “take or pay” clauses. The agreements provide for purchase commitments based on purchase orders. Cancellation fees or other charges may apply and are generally dependent upon whether wafers have been started or the stage of the manufacturing process at which the notice of cancellation is given. As of March 26, 2005, we had foundry commitments of $3.2 million.

     In addition to our wafer supply arrangements, we contract with third-party assembly vendors to package the wafer die into finished products. Assembly vendors provide fixed-cost-per-unit pricing, as is common in the semiconductor industry. We had non-cancelable assembly purchase orders with numerous vendors totaling $1.1 million at March 26, 2005.
     We have transitioned all of our test services to outside third party contractors. Test vendors provide fixed-cost-per-unit pricing, as is common in the semiconductor industry. Our total non-cancelable commitment for outside test services as of March 26, 2005 was $0.6 million.
Other Contingencies
     On June 3, 2003, the Inland Revenue Authority of Singapore (“IRAS”) notified us that it disagreed with our classification of sales to certain disk drive customers from May 1997 through March 1998, resulting in additional goods and services taxes (“GST”) owed by us. After a thorough review of these matters by both the Company and representatives from IRAS, we reached an agreement in the third quarter of 2005 on this and all other audit issues covering years 1997 through 2000. As a result, instead of incurring a liability, the Company received $2.3 million for reclaimed GST collected by vendors during the years 1997 through 2000. This amount has been reported as a reduction of our selling, general and administrative expenses during fiscal year 2005.
8. Legal Matters
Fujitsu
     On October 19, 2001, we filed a lawsuit against Fujitsu, Ltd. (“Fujitsu”) in the United States District Court for the Northern District of California. We asserted claims for breach of contract and anticipatory breach of contract and we sought damages in excess of $46 million. The basis for our complaint was Fujitsu’s refusal to pay for hard disk drive-related chips delivered to and accepted by it in fiscal year 2002. On December 17, 2001, Fujitsu filed an answer and a counterclaim. Fujitsu alleged claims for breach of contract, breach of warranty, quantum meruit/equitable indemnity and declaratory relief. The basis for Fujitsu’s counterclaim was the allegation that certain chips that we sold to Fujitsu were defective and allegedly caused Fujitsu’s hard disk drives to fail. The counterclaim did not specify the damages Fujitsu seeks, other than to allege it has sustained “tens of millions” of dollars in damages. To facilitate the resolution of all claims in one lawsuit, including our claims against potentially responsible third parties, we agreed with Fujitsu to realign our claims so that Fujitsu is the plaintiff and we are the defendant and counterclaimant. This realignment allowed Fujitsu and us to file in the same lawsuit third-party claims alleging breach of contract and warranty against Amkor Technology, Inc., (“Amkor”) the company that recommended and sold to us the packaging materials that caused the alleged defects in our chips. Amkor filed an answer to our third-party claim and a third-party complaint for implied contractual indemnity and breach of warranties against Sumitomo Bakelite Co., Ltd., (“Sumitomo”) the company that sold the allegedly defective molding compound used in these packaging materials.
     On December 5, 2003, for reasons related to the potential lack of jurisdiction for certain claims in federal district court, Fujitsu filed a complaint in California state court alleging claims substantially similar to those filed against us in district court and, in addition, alleging fraud and other related claims against Amkor and Sumitomo. On December 23, 2003, we filed a cross-complaint in California state court alleging the same claims against Fujitsu as we alleged in federal district court and further alleging fraud and other related claims against Amkor and Sumitomo based on their alleged knowledge that the molding compound used in the packaging materials sold to us was defective. On May 10, 2004, the state court issued an order finding the facts supporting the new fraud and negligent misrepresentation causes of action against Amkor and Sumitomo set forth in our cross-complaint insufficient. On June 18, 2004, we filed an amended cross complaint asserting the same fraud and negligent misrepresentation claims against Amkor and Sumitomo in more detail. On August 24, 2004, the court again found the fraud and negligent misrepresentation claims in our cross-complaint were insufficient and granted 30 days for us to file another amended cross-complaint. We filed a second amended cross complaint on October 4, 2004, in which we alleged additional factual detail in support of these claims. On November 23, 2004, the court found that we had alleged sufficient facts to support our fraud and negligent misrepresentation claims against Amkor and Sumitomo.
     To address the claims of all parties and for reasons of judicial economy, the parties jointly moved to stay the federal district court action pending resolution of the state court action. The trial in state court was originally set for January 31, 2005, but was rescheduled by the court on September 21, 2004 for May 2, 2005.
     On April 28, 2005, before the rescheduled trial date, Cirrus Logic, Fujitsu, Amkor, Sumitomo, and Cirrus Logic’s insurance carriers reached an agreement through an arbitration process to settle and release all pending
Page 49 of 71

Table of Contents

claims related to the alleged failure of certain semiconductor integrated circuits sold by Cirrus Logic to Fujitsu. These releases included releases between our insurance carriers and us for any claims related to the litigation with Fujitsu. As part of the settlement, Fujitsu is to receive $45 million from Sumitomo, $40 million from Amkor, and $40 million from Cirrus Logic’s insurance carriers. Fujitsu agreed to pay us a lump sum in the amount of $25 million. We anticipate the final settlement documents will be completed and payment will be received prior to the end of June 2005.
St. Paul Fire and Marine Insurance Company
     On June 9, 2004, we filed a complaint for declaratory relief against St. Paul Fire and Marine Insurance Co. (“St. Paul”) in the United States District Court, Northern District of California. Specifically, the complaint seeks a judicial determination and declaration that the Technology Commercial General Liability Protection (“CGL”) coverage under an insurance policy issued to us by St. Paul provides Cirrus Logic with insurance coverage for Cirrus Logic’s defense of claims brought by Fujitsu in the previously referenced matter. Pursuant to our CGL policy, the costs and expenses associated with defending our lawsuit against Fujitsu would be covered, but would not reduce the policy coverage limits. On August 23, 2004, St. Paul answered the complaint, denying that it was obligated to defend us under the CGL policy.
     Based on the settlement and releases agreed to by the insurance carriers as set forth in the previously referenced matter, we anticipate that, after documentation of the settlement, we will dismiss this case after the insurance carriers have paid Fujitsu and Fujitsu has paid us pursuant to a final settlement agreement.
Wolfson Microelectronics
     On October 9, 2003, we filed a lawsuit against Wolfson Microelectronics, plc, a United Kingdom company and Wolfson Microelectronics Ltd., a Delaware corporation, (collectively “Wolfson”) in the U.S. District Court for the Southern District of California. We alleged that several Wolfson products that incorporate digital-to-analog converters (“DACs”) infringe on our U.S. Patent Nos. 6,492,928 and 6,011,501. We were seeking damages and requesting a permanent injunction against Wolfson from making, using, offering to sell or selling in the U.S. or importing into the U.S. any infringing products. On December 2, 2003, in response to our complaint, Wolfson filed an answer and a counterclaim against us alleging, among other things, unfair competition, tortious interference with prospective economic advantage and tortious interference with contractual relationships. Wolfson’s claims were based primarily on our alleged bad faith in filing suit against Wolfson with the alleged knowledge that one of the two asserted patents was invalid. On April 2, 2004, the district court dismissed Wolfson’s counterclaims for failure to state a claim, although the district court granted leave to amend their complaint. On April 30, 2004, Wolfson amended its counterclaims to include additional allegations concerning alleged communications by Cirrus Logic with Bose Corporation and Argus Electronics relating to Wolfson’s ability to continue to provide Wolfson audio DACs to these customers in the future.
     In addition, on October 14, 2003, we filed a complaint requesting that the U.S. International Trade Commission (the “ITC”) initiate an investigation of Wolfson Microelectronics, plc, for violation of Section 337 of the Tariff Act of 1930, in the importation, sale for importation and sale in the U.S. after importation of certain digital-to-analog converters and other products containing these converters. In our complaint, we asked the ITC to investigate whether certain Wolfson products infringe on one or more of the claims of U.S. Patent No. 6,492,928. On November 10, 2003, the ITC instituted an investigation into Wolfson’s actions based on our allegations. On December 9, 2003, we also requested the ITC to further investigate whether certain Wolfson products infringed on one or more of the claims of U.S. Patent No. 6,011,501. On December 29, 2003, the ITC included our allegations of infringement with respect to U.S. Patent No. 6,011,501 into its investigation. With respect to both patents, we were seeking a permanent exclusion order banning the importation into the U.S. of the allegedly infringing products and a cease-and-desist order halting the sale of these infringing products, as well as other relief the ITC deems appropriate.
     On November 16, 2004, an administrative law judge determined that both patents asserted against Wolfson were valid and infringed. However, with respect to U.S. Patent No. 6,492,928, the administrative law judge also determined that the patent was not enforceable due to our failure to provide certain information to the Patent and Trademark Office as part of our efforts to obtain the patent. The ITC has further determined that it will not review that decision.
     On February 11, 2005, the ITC issued its determination as to the appropriate remedy that we are entitled to with respect to U.S. Patent No. 6,011,501. Specifically, the ITC issued a limited exclusion order prohibiting the importation of three models of Wolfson’s DACs that infringe the ‘501 patent.
     We settled all of our outstanding litigation matters with Wolfson on March 24, 2005. Under the settlement agreement, the parties agreed to withdraw all outstanding claims and counterclaims in the U.S. District Court proceedings. In addition, the parties submitted an application to the ITC for the withdrawal of the exclusion order
Page 50 of 71

that the ITC issued in February 2005 in relation to the ‘501 patent. As part of the settlement, the parties have agreed not to assert any patents against each other for a period of three years. In addition, Wolfson agreed not to make, use, sell, offer for sale, and/or import into the United States any DACs that practiced the ‘501 patent. No payments were made, or will be made, by either party as part of the settlement.
Silvaco Data Systems
     On December 8, 2004, Silvaco Data Systems (“Silvaco”) filed suit against us, and others, alleging misappropriation of trade secrets, conversion, unfair business practices, and civil conspiracy. Silvaco’s complaint stems from a trade secret dispute between Silvaco and a software vendor, Circuit Semantics, Inc., who supplies us with certain software design tools. Silvaco alleges that our use of Circuit Semantic’s design tools infringes upon Silvaco’s trade secrets and that we are liable for compensatory damages in the sum of $10 million. Silvaco has not indicated how it will substantiate this amount of damages and we are unable to reasonably estimate the amount of damages, if any.
     On January 25, 2005, we answered Silvaco’s complaint by denying any wrong-doing. In addition, we filed a cross-complaint against Silvaco alleging breach of contract relating to Silvaco’s refusal to provide certain technology that would enable us to use certain unrelated software tools.
     We intend to defend the lawsuit vigorously. In addition, Circuit Semantics is obligated to defend and indemnify us pursuant to our license agreement with them for the software. However, we cannot predict the ultimate outcome of this litigation and we are unable to estimate any potential liability we may incur.
Facilities Under Operating Lease Agreements
     We lease our facilities under operating lease agreements. Our principal facility, located in Austin, Texas, is 197,000 square feet and houses our headquarters and engineering facility. The lease agreement for this facility includes a potential obligation to enter into another lease agreement for a period of 10 years for an additional 64,000 square feet in a new building to be built on property next to our current facility. This obligation was contingent upon construction beginning on the new facility before November 10, 2004. On September 14, 2004, our landlord provided us notice that it had elected to construct the new building. However, as of May 27, 2005, actual construction on the new building had not commenced. On November 12, 2004, we filed suit against our landlord in the state district court of Travis County, Texas seeking declaratory relief as to our obligations under the current operating lease agreement. Specifically, we seek a declaration that we have no obligation to lease an additional two floors of space because the landlord did not commence construction of the new facility before November 10, 2004. Trial has been set in this matter for December 2005.
     In the event that the court determines that the owner of the property has strictly complied with all notices and conditions precedent to entering a new lease, we estimate that the yearly minimum future lease payments could be as much as $1.7 million. In addition, we may be required to provide a cash deposit of $200,000 as well as segregating and restricting an additional $3 million of our available cash balance in the form of a letter of credit. If we are required to enter into a new lease, we are unable to estimate when these potential obligations would begin because it is uncertain when construction will actually be completed.
Other Claims
     From time to time, other various claims, charges and litigation are asserted or commenced against us arising from, or related to, contractual matters, intellectual property, employment disputes, as well as other issues. Frequent claims and litigation involving these types of issues are not uncommon in the integrated circuit (“IC”) industry. As to any of these claims or litigation, we cannot predict the ultimate outcome with certainty.
9. Litigation Settlement
Western Digital
     On August 22, 2003, we signed an agreement to settle prior litigation with Western Digital Corporation and its Malaysian subsidiary, Western Digital (M) SDN.BHD, (“WD”). Under the terms of the agreement, WD made a one-time payment to us of $45 million on October 16, 2003. We recorded the settlement as a credit to operating expense during the third quarter of fiscal year 2004 when the payment was received. Part of the $45 million received from WD represented a recovery of bad debt expense recorded in a prior year of approximately $26.5 million.

10. Patent agreement and settlements, net
     During the third quarter of fiscal year 2005, we released $0.6 million in legal fees originally accrued in connection with the transaction with Broadcom Corporation for certain U.S. and foreign patents. The excess accrual was related to differences from our original estimate and the actual fees incurred related to this transaction.
     On August 11, 2003, we entered into a Patent Sale, Assignment and Cross-License Agreement with NVIDIA and NVIDIA International, Inc. to settle certain pending litigation. As a result of this agreement, NVIDIA paid us $9 million on August 11, 2003. On September 23, 2003, we entered into a Patent Sale, Assignment and Cross-License Agreement with ATI and ATI International SRL to settle certain additional pending litigation. As a result of this agreement, ATI paid us $9 million on October 2, 2003. Under the terms of a contingency fee arrangement, we were obligated to pay outside counsel a percentage of these settlements. During the fourth quarter of fiscal year 2004, we received a net $17 million related to a transaction with Broadcom Corporation for certain U.S. and foreign patents. Both the agreement and settlements were recorded as a separate line item on the statement of operations in operating expenses under the heading “Patent agreement and settlements, net.”
11. Restructuring Costs and Other
     During the fiscal year 2005, we recorded a charge of $2.9 million for severance related items associated with workforce reductions, which affected approximately 100 individuals worldwide in various job functions. In connection with these reductions, we also recorded an impairment charge of $5.0 million for the abandonment of certain computer aided design (“CAD”) and other software tools that will no longer be utilized. In addition, we recorded a net $1.4 million charge due to facility related consolidations, primarily in Colorado and California. These facility charges included a benefit of $0.5 million resulting from a lease buyout that we completed in the second quarter of fiscal year 2005. The cost for this leased facility had been partially accrued when a portion of the space was vacated during our fiscal year 2002 workforce reductions. During the first quarter of fiscal year 2005, the remaining cost was accrued when the leased space was completely vacated. The total buyout amount of $4.3 million was less than the recorded liability and hence, we recognized the benefit of $0.5 million from this transaction against the restructuring expenses incurred during the second quarter of fiscal year 2005. Additionally, we recorded an impairment charge of $0.1 million for property and equipment associated with our Pune, India facility closure. Our severance commitments for the fiscal year 2005 action will be completed during fiscal year 2006.
     The following table sets forth the activity in our fiscal year 2005 restructuring accrual (in thousands)

     During fiscal year 2004, we recorded a charge of $1.7 million in operating expenses primarily related to severance for headcount reductions. We eliminated approximately 130 positions from various job classes and functions during fiscal year 2004, with the majority of the reductions in Austin, Texas, primarily in selling, general and administrative functions and in our Colorado operations, primarily in engineering. Included in this reduction was the elimination of 64 of approximately 120 test operation positions and a total severance charge of approximately $0.4 million as part of our previously announced plan to reduce headcount associated with our outsourcing agreement with ChipPAC. Also during fiscal year 2004, we recorded a restructuring charge of $6.2 million in operating expenses for facility consolidations primarily in California and Texas, an impairment charge of $1.5 million for property and equipment associated with our Austin, Texas facility consolidation and an impairment charge of $0.2 million for property and equipment associated with our Tokyo, Japan facility consolidation. During fiscal year 2005, we re-assessed our sublease assumptions related to our restructured facilities and determined that an additional $0.2 million was required due to our inability to sublease certain facilities. Our facility commitments for the fiscal year 2004 actions will be completed during fiscal year 2013.

     During fiscal year 2003, we eliminated approximately 290 employee positions worldwide, or approximately 25 percent of the total workforce, from various business functions and job classes as a continuation of our fiscal year 2002 effort to further reduce costs and align operating expenses with our revenue model. In fiscal year 2003, we recorded a restructuring charge of $3.8 million in operating expenses for costs associated with these workforce reductions, a non-cash charge of $2.5 million to fully expense certain intangible, fixed and other assets that would no longer be used as a result of our workforce reductions and $0.8 million related to facility consolidations. As part of these restructuring activities, we closed our wireless product line, acquired in October 2001 in connection with our acquisition of ShareWave and the associated El Dorado Hills, California office. Our facility commitments for the fiscal year 2003 actions will be completed during fiscal year 2007.

     The following table sets forth the activity in our fiscal year 2002 restructuring accrual (in thousands). In fiscal year 2003, we recorded a net additional charge of $1.5 million related primarily to a reduction in the sublease assumptions for a facility we initially restructured during fiscal year 2002, mainly due to the depressed real estate market in that area. During fiscal year 2004, we modified our sublease assumptions due to the continued depressed real estate market and took another charge of $121 thousand related to some of these restructured facilities. The remaining balance for the fiscal year 2002 restructuring relates to a contractual obligation that will expire in fiscal year 2006.

     As of March 26, 2005, we have a remaining restructuring accrual for all of our past restructurings of $5.5 million, primarily related to net lease expenses that will be paid over the respective lease terms through fiscal year 2013, along with other anticipated lease termination costs. We have classified the short-term portion of our restructuring activities as “Other accrued liabilities.”
12. Employee Benefit Plans
     We have a 401(k) Profit Sharing Plan (the “Plan”) covering substantially all of our qualifying domestic employees. Under the Plan, employees may elect to contribute up to 75 percent of their annual compensation, subject to annual IRS limitations. We match 50 percent of the first 6 percent of the employees’ annual contribution to the plan. During fiscal years 2005, 2004, and 2003, we made matching employee contributions for a total of approximately $0.9 million, $1.2 million, and $1.5 million, respectively.
13. Stockholders’ Equity
Employee Stock Purchase Plan
     In March 1989, we adopted the 1989 Employee Stock Purchase Plan (“ESPP”). As of March 26, 2005, 1.3 million shares of common stock were reserved for future issuance under this plan. During fiscal years 2005, 2004, and 2003, we issued 422,000, 362,000, and 400,000 shares, respectively, under the ESPP.
Preferred Stock
     We have not issued any of the authorized 1.5 million shares of Series A Participating Preferred Stock. On May 24, 2005, the Board of Directors of the Company approved an amendment (the “Amendment”) to the Amended and Restated Rights Agreement, dated as of February 17, 1999, between the Company and BankBoston, N.A., as Rights Agent. The Amendment accelerates the termination of the Company’s preferred stock purchase rights (the “Rights”) from the close of business on May 4, 2008 to the close of business on May 26, 2005. On May 27, 2005, the Company plans to file a Certificate of Elimination with the Secretary of State of the State of Delaware which will have the effect of eliminating from the Company’s Certificate of Incorporation all references to the Series A Participating Preferred Stock of the Company and returning these shares to the status of undesignated shares of authorized Preferred Stock of the Company.
Stock Option Plans
     We have various stock option plans (the “Option Plans”) under which officers, employees, non-employee directors and consultants may be granted qualified and non-qualified options to purchase shares of our authorized but not issued common stock. Options are generally priced at the fair market value of the stock on the date of grant. Options granted to employees are exercisable upon vesting, generally over four years and certain options granted to non-employee directors are exercisable upon grant. Options expire no later than ten years from the date of grant.
     As of March 26, 2005, approximately 27.0 million shares of common stock were reserved for issuance under the Option Plans.

Stock-Based Compensation
     If we had recorded compensation cost for our stock option plans based upon the Black-Scholes fair value at the grant date for awards under the Option Plans consistent with the optional methodology prescribed under Statement of Financial Accounting Standard No. 123 (“SFAS 123”), “Accounting for Stock-Based Compensation,” the net income (loss) and earnings per share would have been as shown below (in thousands, except per share data):

     For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the vesting period (for options) and the six-month purchase period (for stock purchases under the ESPP) using the straight-line method.
     The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Because our options have characteristics different from those of traded options and because changes in the subjective input assumptions can materially affect the fair value estimate, in the opinion of management, the existing models do not necessarily provide a reliable single measure of the fair value of its options. The effects on pro forma disclosure of applying SFAS 123 for prior years are not likely to be representative of the effects on pro forma disclosures for future years.
     We estimated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model using a dividend yield of zero and the following additional weighted-average assumptions:

     During fiscal years 2005, 2004, and 2003, all options were granted at an exercise price equal to the closing market price on the grant date. Using the Black-Scholes option valuation model, the weighted average estimated fair values of employee stock options granted in fiscal years 2005, 2004, and 2003 were $3.60, $3.67, and $4.07, respectively. The weighted average estimated fair values for purchase rights granted under the ESPP for fiscal years 2005, 2004, and 2003 were $2.25, $2.47, and $3.40, respectively.
Stock Option Exchange
     On December 20, 2002, we completed a stock option exchange program offered to all eligible option holders. Under the exchange offer, eligible employees had the opportunity to tender for cancellation certain stock options in exchange for new options to be granted at least six months and one day after the cancellation of the tendered options. Members of the Board of Directors and executive officers were not eligible to participate in the exchange program. Each eligible participant received a new option to purchase 0.75 share of common stock for each option to purchase one share of common stock cancelled. We accepted approximately 3.4 million options for exchange in December 2002 and granted approximately 2.3 million new options on June 23, 2003. The exercise price per share of the new options was $3.40, equal to the fair market value of our common stock on the date of the grant, as compared to the average exercise price per share of the old options of $18.11. We did not record any compensation expense as a result of the exchange program.
Rights Plan
     In May 1998, the Board of Directors declared a dividend of one preferred share purchase right (a “Right”) for each share of common stock outstanding held as of May 15, 1998. Each Right would have entitled stockholders to purchase one one-hundredth of a share of our Series A Participating Preferred Stock at an exercise price of $60. The Rights only became exercisable in certain limited circumstances following the tenth day after a person or group announces acquisitions of or tender offers for 15 percent or more of our common stock. For a limited period following the announcement of any such acquisition or offer, the Rights were redeemable by us at a price of $0.01 per Right. If the Rights were not redeemed, each Right then entitled the holder to purchase common stock having the value of twice the exercise price. For a limited period after the Rights were exercisable, each Right, at the discretion of the Board, could be exchanged for one share of common stock per Right. The Rights were originally scheduled to expire in fiscal year 2009.

     On May 24, 2005, the Board of Directors of the Company approved an amendment to the Amended and Restated Rights Agreement, dated as of February 17, 1999, between the Company and BankBoston, N.A., as Rights Agent. The Amendment accelerates the termination of the Company’s preferred stock purchase rights from the close of business on May 4, 2008 to the close of business on May 26, 2005. On May 27, 2005, the Company plans to file a Certificate of Elimination with the Secretary of State of the State of Delaware which will have the effect of eliminating from the Company’s Certificate of Incorporation all references to the Series A Participating Preferred Stock of the Company and returning these shares to the status of undesignated shares of authorized Preferred Stock of the Company.
14. Accumulated Other Comprehensive Income (Loss)
     Our accumulated other comprehensive income (loss) is comprised of foreign currency translation adjustments and unrealized gains and losses on investments classified as available-for-sale. The foreign currency translation adjustments are not currently adjusted for income taxes because they relate to indefinite investments in non-U.S. subsidiaries that have since changed from a foreign functional currency to a U.S dollar functional currency. Additionally, there were no income taxes provided for the unrealized gains and losses due to the recording of a full valuation allowance against net deferred tax assets.
     The following table summarizes the changes in the components of accumulated other comprehensive income (loss) (in thousands):

     SFAS No. 109, “Accounting for Income Taxes” provides for the recognition of deferred tax assets if realization of such assets is more likely than not. We have provided a valuation allowance equal to our net deferred tax assets due to uncertainties regarding their realization. We evaluate the realizability of our deferred tax assets on a quarterly basis.
     The valuation allowance increased by $133.4 million in fiscal year 2005 and decreased by $9.8 million in fiscal year 2004. During fiscal year 2005, we recorded nonrecurring tax benefits totaling $21.3 million that consisted of the reversal of prior year Federal and foreign tax liabilities. These reversals were due to the expiration of the statute of limitations for years in which certain potential Federal and foreign tax liabilities existed. At March 26, 2005, we had Federal net operating losses carryforwards of $450.1 million. Of that amount, $75.4 million relates to companies we acquired during fiscal year 2002 and are, therefore, subject to certain limitations under Section 382 of the Internal Revenue Code. In addition, approximately $23.5 million of the federal net operating loss is attributable to employee stock option deductions, the benefit from which will be allocated to additional paid-in capital rather than current earnings if subsequently realized. We have net operating losses in various states that total $160.4 million. The Federal net operating loss carryforwards expire in fiscal years 2009 through 2025. The state net operating loss carryforwards expire in fiscal years 2006 through 2025.
     There are Federal research and development credit carryforwards of $20.1 million that expire in fiscal years 2007 through 2025. There are $14.4 million of state research and development credits. Of that amount, $2.7 million will expire in fiscal years 2021 through 2025. The remaining $11.7 million of state research and development credits are not subject to expiration. The state investment credits of $1.5 million will expire in fiscal years 2006 through 2010.
     The American Jobs Creation Act of 2004 (the “Act”) creates a temporary incentive for U.S. corporations to repatriate accumulated income earned abroad by providing an 85 percent dividends-received deduction for certain dividends from controlled foreign corporations. We have completed our evaluation of the repatriation provision of the Act and concluded that we will not benefit from it due to the limitations it places on net operating loss carryforwards and credits. Therefore, we have not recognized any additional income tax expense or benefit as a result of the repatriation provision.
     We have approximately $6.3 million of cumulative undistributed earnings in certain non-U.S. subsidiaries. We have not recognized a deferred tax liability on these undistributed earnings because the Company currently intends to reinvest these earnings in operations outside the U.S. The unrecognized deferred tax liability on these earnings is approximately $2.3 million. With our current tax attributes, if the earnings were distributed, we would most likely not accrue any additional income tax expense because this income would be offset by our net operating loss carryforwards and other future deduction.

     Our taxes payable balance is comprised primarily of tax contingencies that are recorded to address exposures involving tax positions we have taken that could be challenged by taxing authorities. These exposures result from the varying application of statutes, rules, regulations, and interpretations. Our tax contingencies are established based on past experiences and judgments about potential actions by taxing jurisdictions. Our tax contingencies relate, in large part, to transfer pricing positions we have taken in a variety of countries in which we operate. The ultimate resolution of these matters may be materially greater or less than the amount that we have accrued. As of the end of fiscal year 2004, we had also accrued for certain domestic tax issues, but the statute of limitations on those issues expired during fiscal year 2005.
     During fiscal year 2004, the Internal Revenue Service completed its examination of our U.S. Federal Income tax returns for fiscal years 1998, 1999, 2000 and 2001. On May 17, 2004, we received a refund of $1.7 million, which had been delayed pending the completion of the examination, which was recorded as “Benefit for income taxes.”
16. Segment Information
     We are a premier supplier of high- precision analog and mixed-signal integrated circuits (“ICs”) for a broad range of consumer and industrial markets. We develop and market integrated ICs and embedded software used by original equipment manufacturers. We also provide complete system reference designs based on our technology that enable our customers to bring products to market in a timely and cost-effective manner. We determine our operating segments in accordance with SFAS 131. Our chief executive office (“CEO”) has been identified as the chief operating decision maker as defined by SFAS 131.
     Our CEO receives and uses enterprise-wide financial information to assess financial performance and allocate resources, rather than detailed information at a product line level. Additionally, our product lines have similar characteristics and customers. They share operations support functions such as sales, public relations, production and logistics, in addition to the general and administrative functions of human resources, legal, finance and information technology. Accordingly, we operate in one operating segment with four different product lines.
     Our revenue by product line is as follows (in thousands):

18. Related Party Transactions
     The Company had two outstanding loans to Mr. David D. French (“Mr. French”), President and Chief Executive Officer and only one of which remains outstanding as of March 26, 2005. Both loans were “grandfathered” under Section 402 of the Sarbanes Oxley Act of 2002, which prohibits loans to directors and executive officers that are made, renewed or materially modified after July 30, 2002. Neither of the loans described below have been modified or renewed since the company made them to Mr. French.
     In October 1998, the Company extended a loan to Mr. French for the purchase of his principal residence in Texas. The original principal amount of the loan was $721,899 and carries an interest rate of 5.64 percent per annum. The principal and accrued interest is due and payable on the earlier of (i) September 1, 2013, (ii) 180 days following the date of the termination of his employment for any reason, or (iii) upon sale of the residence. In the event of his death or disability, the principal and accrued interest will be forgiven, subject to applicable law. The aggregate amount of principal plus accrued interest outstanding under this loan at the end of fiscal years 2005 and 2004 was $1,030,770 and $975,889, respectively. This loan is currently classified as a long-term asset on the balance sheet under “Other assets.”
     In July 1999, the Company also advanced a personal loan in the original principal amount of $750,000 to Mr. French. The note bears interest at 5.82 percent per annum and was secured by 90,000 shares of the Company’s common stock held in escrow. The note and accrued interest were due and payable upon the earlier of (i) July 21, 2004 or (ii) 180 days following the termination of Mr. French’s employment. The aggregate amount of principal plus accrued interest outstanding under this loan at the end of fiscal year 2004 was $978,079 and was classified as a current asset. During fiscal year 2005, the loan accrued an additional $17,397 of interest. On July 21, 2004, Mr. French fulfilled his obligation with respect to this loan and paid the final outstanding balance of $995,476.

19. Subsequent Events
Video Divestiture
     On April 25, 2005, we announced our intentions to divest our digital video product line. During the first quarter of fiscal year 2006, we will classify the related assets of approximately $6 million to assets held for sale on the balance sheet in accordance with SFAS 144. On May 24, 2005, we signed a definitive agreement to sell our digital video product line to Magnum Semiconductor Inc., a privately held company formed by an investment group led by Investcorp and August Capital. By divesting the video product line, we are focusing on our core analog, mixed-signal and embedded IC product lines for audio and industrial markets. With this focus, we are poised to leverage our intellectual property and high-margin analog product lines to drive growth and sustainable profitability. The transaction is structured as an asset sale and is currently expected to close in approximately 45 to 75 days. As consideration for the sale of these assets, we will receive a minority equity ownership position in Magnum Semiconductor and we anticipate we will account for our ownership position under the cost method of accounting. Upon completion of the transaction, we expect to record a one-time charge of approximately $7 million, which consists primarily of $5 million in anticipated costs associated with our exit from excess leased facilities and an estimated $1.5 million in expected professional fees associated with the transaction. The transaction is subject to certain closing conditions, including conditions requiring that certain approvals, consents and agreements be obtained.
Fujitsu Settlement
     As of March 26, 2005, Cirrus Logic, Fujitsu Ltd. (“Fujitsu”), Amkor Technology Inc. (“Amkor”), and Sumitomo Bakelite Co., Ltd. (“Sumitomo”) were all parties awaiting trial with respect to the litigation described in Note 8 to these Consolidated Financial Statements. The trial in state court was originally set for January 31, 2005, but was rescheduled by the court on September 21, 2004 for May 2, 2005. On April 28, 2005, before the rescheduled trial date, Cirrus Logic, Fujitsu, Amkor, Sumitomo, and Cirrus Logic’s insurance carriers reached an agreement through an arbitration process to settle and release all pending claims related to the alleged failure of certain semiconductor integrated circuits sold by Cirrus Logic to Fujitsu. These releases included releases between our insurance carriers and us for any claims related to the litigation with Fujitsu. As part of the settlement, Fujitsu is to receive $45 million from Sumitomo, $40 million from Amkor, and $40 million from Cirrus Logic’s insurance carriers. Fujitsu agreed to pay us a lump sum in the amount of $25 million. We anticipate the final settlement documents will be completed and payment will be received prior to the end of June 2005
ITEM 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
     None.
ITEM 9A .Controls and Procedures
Evaluation of disclosure control and procedures

§   	We maintain disclosure controls and procedures that are intended to ensure that the information required to be disclosed in our Securities Exchange Act of 1934 (the “Exchange Act”) filings is properly and timely recorded and reported. Our management is responsible for establishing and maintaining adequate internal controls over financial reporting. We have formed a Disclosure Review Committee comprised of key individuals from several disciplines in the Company who are involved in the disclosure and reporting process. This committee, which is led by the Vice President of Finance and Treasurer, meets periodically to ensure the timeliness, accuracy and completeness of the information required to be disclosed in our filings.	
 	
§   	As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15 of the Exchange Act. Based upon that evaluation, the CEO and the Chief Financial Officer (“CFO”) concluded that, as of March 26, 2005, our disclosure controls and procedures were effective at providing reasonable assurance that information required to be disclosed by us in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that our controls and procedures are effective in timely alerting them to material information required to be included in this report.

Changes in control over financial reporting

§   	There has been no change in our internal control over financial reporting that occurred during our most recent fiscal quarter that has materially affected or is reasonably likely to materially affect our internal control over financial reporting.	
 	
§   	In designing and evaluating our disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives due to numerous factors, ranging from errors to conscious acts of an individual, or individuals acting together. Because of inherent limitations in a cost-effective control system, misstatements due to error and/or fraud may occur and not be detected. Our disclosure control procedures are designed to provide reasonable assurance that such controls and procedures will meet their objectives and the CEO and CFO have concluded that the controls and procedures do in fact provide reasonable assurance of achieving the desired control objectives.	
Management’s Annual Report on Internal Control over Financial Reporting

§   	Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision and with the participation of our management, including our President and Chief Executive Officer and Chief Financial Officer, we assessed the effectiveness of our internal control over financial reporting as of the end of the period covered by this report based on the framework in “Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions and that the degree of compliance with the policies or procedures may deteriorate. Based on it assessment of internal control over financial reporting, management has concluded that, as of March 26, 2005, our internal control over financial reporting was effective to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements for external purposes in accordance with U. S. generally accepted accounting principles. Our independent registered public accounting firm, Ernst & Young LLP, has issued an attestation report on our management’s assessment of our internal control over financial reporting.
