PART I

ITEM 1.  	Business	
 
Cirrus Logic, Inc. (“Cirrus Logic,” “Cirrus,” “We,” “Us,” “Our,” or the “Company”) develops high-precision, analog and mixed-signal integrated circuits (“ICs”) for a broad range of audio and energy markets. Building on our diverse analog mixed-signal patent portfolio, Cirrus Logic delivers highly optimized products for consumer and commercial audio, automotive entertainment, and targeted industrial and energy-related applications. We also develop ICs, board-level modules and hybrids for high-power amplifier applications branded as the Apex Precision Power tm (“Apex”) line of products.
 
We were incorporated in California in 1984, became a public company in 1989 and were reincorporated in the State of Delaware in February 1999. Our primary facility housing engineering, sales and marketing, and administrative functions is located in Austin, Texas. In addition, we have an engineering, administrative, and assembly facility in Tucson, Arizona, as well as sales locations throughout the United States. We also serve customers from international sales offices in Europe and Asia, including the People’s Republic of China, Hong Kong, South Korea, Japan, Singapore, Taiwan and the United Kingdom. Our common stock, which has been publicly traded since 1989, is listed on the NASDAQ Global Select Market under the symbol CRUS.
 
We maintain a Web site with the address www.cirrus.com . We are not including the information contained on our Web site as a part of, or incorporating it by reference into, this Annual Report on Form 10-K.

Background of the Semiconductor Industry
 
In general, the semiconductor industry produces three types of products: analog, digital and mixed-signal. Analog semiconductors process a continuous range of signals that can represent functions such as temperature, speed, pressure and sound. Digital semiconductors process information represented by discrete values, for example, 0s and 1s. Mixed-signal semiconductors combine analog and digital circuits in a single product. The design of the analog component of a mixed-signal IC is particularly complex and difficult, and requires experienced engineers to optimize speed, power and resolution within standard manufacturing processes.
 
The convergence and sophistication of our customers’ products, such as portable audio applications, home entertainment and automotive audio devices, is made possible in part by advances in semiconductor technology. Semiconductor companies are attempting to differentiate their products based on offering new features and functionality to customers, while at the same time shrinking product sizes, reducing power consumption, and lowering overall system costs.
 
Due to the extremely high costs involved in developing and operating a wafer fabrication facility, many semiconductor companies, including Cirrus, rely on third party foundries to manufacture their IC’s. We believe that our fabless manufacturing model significantly reduces our capital requirements and allows us to focus our resources on design, development, and marketing of our ICs.
 
Segments
 
We determine our operating segments in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280, “Segment Reporting.” Our Chief Executive Officer (“CEO”) has been identified as the chief operating decision maker as defined by FASB ASC Topic 280.
 
The Company operates and tracks its results in one reportable segment based on the aggregation of activity from its two product lines under ASC Topic 280. 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, supply chain management, various research and development and engineering support, in addition to the general and administrative functions of human resources, legal, finance and information technology. Therefore, there is no complete, discrete financial information maintained for these product lines. We report revenue in two product categories: audio products and energy products. For fiscal years 2011, 2010, and 2009, audio product sales were $264.8 million, $153.7 million, and $97.3 million, respectively. For fiscal years 2011, 2010, and 2009, energy product sales were $104.7 million, $67.3 million, and $77.3 million, respectively.
 
See Note 17, “ Segment Information, ” of the Notes to Consolidated Financial Statements contained in Item 8 for further details including sales by geographic locations and for property, plant and equipment, net, by geographic locations.

systems. In networked digital audio applications, our proprietary CobraNet controller ICs and modules enable delivery of uncompressed digital audio over Ethernet networks, co-existing with standard Ethernet network data traffic.
 
ENERGY PRODUCTS
 
We provide high-precision analog and mixed-signal ICs for targeted energy control, energy measurement and energy exploration applications, as well as ICs, board-level modules, and hybrids from the Apex brand of products for high-power PWM and power amplifier applications. We have approximately 450 active proprietary products which include ADCs, DACs, linear amplifiers, PWM amplifiers, and amplifier ICs. Our products are used in a wide array of high-precision, energy-related applications including digital utility meters, power supplies, lighting ballasts, motor control, energy exploration, and high-power systems. New additions to our proprietary product portfolio in the past fiscal year include:

 	§   	The CS1500 and CS1600 are digital power factor correction (“PFC”) ICs that support digital PFC for power supplies used in digital televisions, personal computers, notebook computers, and fluorescent and LED lighting systems. Both chips are based on Cirrus Logic’s EXL Core tm technology, which is a key component of the company’s long-term product roadmap in energy products to help customers develop smarter, greener energy products.	
 
Customers, Marketing, and Sales
 
We offer approximately 700 products to more than 3,000 active customers worldwide through both direct and indirect sales channels. Our major customers are among the world’s leading electronics manufacturers. We target both large existing and emerging growth consumer electronic and energy markets that derive value from our expertise in advanced analog and mixed-signal design processing, systems-level integrated circuit engineering and embedded software development. We derive our sales both domestically and from a variety of locations across the world, including the People’s Republic of China, the European Union, Hong Kong, Japan, South Korea, Taiwan, and the United Kingdom. Our domestic sales force includes a network of regional direct sales offices located in California, Massachusetts, Ohio, Nevada, North Carolina, and Texas. International sales offices and staff are located in France, Germany, Hong Kong, Shanghai and Shenzhen in the People’s Republic of China, Singapore, South Korea, Taiwan, Japan and the United Kingdom. We supplement our direct sales force with external sales representatives and distributors. Our technical support staff is located in Texas and Arizona. Our worldwide sales force provides geographically specific support to our customers and specialized selling of product lines with unique customer bases. See Note 17, “ Segment Information, ” of the Notes to Consolidated Financial Statements contained in Item 8 for further detail and for additional disclosure regarding sales by geographic locations, and for property, plant and equipment, net, by geographic locations.
 
Since the components we produce are largely proprietary and generally not available from second sources, we consider our end customer to be the entity specifying the use of our component in their design. These end customers may then purchase our products directly from us, from an external sales representative or distributor, or through a third party manufacturer contracted to produce their designs. For fiscal years 2011, 2010, and 2009, our ten largest end customers represented approximately 62 percent, 54 percent, and 36 percent of our sales. For fiscal years 2011, 2010, and 2009, we had one end customer, Apple Inc., who purchased through multiple contract manufacturers and represented approximately 47 percent, 35 percent, and 16 percent of the Company’s total sales, respectively. For fiscal years 2011, 2010, and 2009, we had one distributor, Avnet Inc., who represented 24 percent, 26 percent, and 33 percent of our sales, respectively.
 
Manufacturing
 
As a fabless semiconductor company, we contract with third parties for wafer fabrication and nearly all of our assembly and test operations. We use multiple wafer foundries, assembly sources and test houses in the production of our inventory. The company owns a 54,000 square foot facility in Tucson, Arizona, which serves as the assembly and test facility for its Apex product line. With the exception of these Apex products, our outsourced manufacturing strategy allows us to concentrate on our design strengths, minimize fixed costs and

capital expenditures while giving us access to advanced manufacturing facilities, and provide the flexibility to source multiple leading-edge technologies through strategic relationships. After wafer fabrication by the foundry, third-party assembly vendors package the wafer die. The finished products are then tested before shipment to our customers. While we do have some redundancy of fabrication processes by using multiple outside foundries, any interruption of supply by one or more of these foundries could materially impact us. As a result, we maintain some amount of business interruption insurance to help reduce the risk of wafer supply interruption, but we are not fully insured against such risk. Our supply chain management organization is responsible for the management of all aspects of the manufacturing, assembly, and testing of our products, including process and package development, test program development, and production testing of products in accordance with our ISO-certified quality management system.
 
Although our products are made from basic materials (principally silicon, metals and plastics), all of which are available from a number of suppliers, capacity at wafer foundries sometimes becomes constrained. The limited availability of certain materials may impact our suppliers’ ability to meet our demand needs or impact the price we are charged. The prices of certain other basic materials, such as metals, gases and chemicals used in the production of circuits can increase as demand grows for these basic commodities. In most cases, we do not procure these materials ourselves; nevertheless, we are reliant on such materials for producing our products because our outside foundry and package and test subcontractors must procure them. To help mitigate risks associated with constrained capacity, we use multiple foundries.
 
Patents, Licenses and Trademarks
 
We rely on patent, copyright, trademark, and trade secret laws to protect our intellectual property, products, and technology. As of March 26, 2011, we held approximately 1,100 granted U.S. patents, 100 U.S. pending patent applications and various corresponding international patents and applications. Our U.S. patents expire in calendar years 2011 through 2029. While our patents are an important element of our success, our business as a whole is not dependent on any one patent or group of patents. We do not anticipate any material effect on our business due to any patents expiring in 2011, and we continue to obtain new patents through our ongoing research and development.
 
We have maintained U.S. federal trademark registrations for CIRRUS LOGIC, CIRRUS, Cirrus Logic logo designs, CRYSTAL and APEX PRECISION POWER. 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 2011, 2010 and 2009 were $63.9 million, $51.4 million and $44.3 million, respectively. Our future success is highly dependent upon our ability to develop complex new products, to transfer new products to volume production, to introduce them into the marketplace in a timely fashion, and to have them selected for design into products of 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. Our ability to compete effectively and to expand our business will depend on our ability to continue to recruit key engineering talent, to execute on new product developments, to persuade customers to design-in these new

Table of Contents

products into their applications, and to provide lower-cost versions of existing products. We compete with other semiconductor suppliers that offer standard semiconductors, application-specific standard product and fully customized ICs, including embedded software, chip and board-level products.
 
While no single company competes with us in all of our product lines, we face significant competition in all markets where our products are available. 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, which includes 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.
 
Product life cycles may 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 frequent opportunities to displace competitors in products that have previously not utilized our design. The industrial and automotive markets typically have longer life cycles, which provide continued revenue streams over long periods of time.
 
Backlog
 
Sales are made primarily pursuant to short-term purchase orders for delivery of 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. The majority of our backlog is typically requested for delivery within six months. In markets where the end system life cycles are relatively short, customers typically request delivery in six to ten weeks. We believe a backlog analysis at any given time gives little indication of our future business except on a short-term basis, principally within the next 60 days.
 
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 because of changes in customer needs or industry conditions. As a result, we believe that our backlog at any given time is an incomplete indicator of future sales.
 
Employees
 
As of March 26, 2011, we had 570 full-time employees, an increase of 65 employees, or 13 percent, over the end of fiscal year 2010. Of these employees, 54 percent were engaged in research and product development activities, 34 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.
 
We have never had a work stoppage and none of our employees are represented by collective bargaining agreements. We consider our employee relations to be good.

We undertake no obligation to revise or update publicly any forward-looking statement for any reason.

Item 1A.  	Risk Factors	
 
Our business faces significant risks. The risk factors set forth below may not be the only risks that we face and there is a risk that we may have failed to identify all possible risk factors. 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 Cirrus Logic’s filings with the 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.
 
We depend on a limited number of customers and distributors for a substantial portion of our sales, and the loss of, or a significant reduction in orders from, any key customer or distributor could significantly reduce our sales.
 
While we generate sales from a broad base of customers worldwide, the loss of any of our key customers, or a significant reduction in sales to any one of them, would significantly reduce our sales and adversely affect our business. For the twelve month periods ending March 26, 2011, and March 27, 2010, our ten largest end customers represented approximately 62 percent and 54 percent of our sales, respectively. For the twelve month periods ending March 26, 2011, and March 27, 2010, we had one end customer, Apple Inc., who purchased through multiple contract manufacturers and represented approximately 47 percent and 35 percent of the Company’s total sales, respectively. For the twelve month periods ending March 26, 2011, and March 27, 2010, we had one distributor, Avnet Inc., who represented 24 percent and 26 percent of our sales, respectively.
 
We may not be able to maintain or increase sales to certain of our key customers for a variety of reasons, including the following:

 	§   	most of our customers can stop incorporating our products into their own products with limited notice to us and suffer little or no penalty;	
 		
 	§   	our agreements with our customers typically do not require them to purchase a minimum quantity of our products;	
 		
 	§   	many of our customers have pre-existing or concurrent relationships with our current or potential competitors that may affect the customers’ decisions to purchase our products;	
 		
 	§   	our customers face intense competition from other manufacturers that do not use our products; and	
 		
 	§   	our customers regularly evaluate alternative sources of supply in order to diversify their supplier base, which increases their negotiating leverage with us and their ability to obtain components from alternative sources.

Table of Contents

Our key customer relationships often require us to develop new products that may involve significant technological challenges. Our customers frequently place considerable pressure on us to meet their tight development schedules. In addition, we may from time to time enter into customer agreements providing for exclusivity periods during which we may only sell specified products or technology to that customer. Accordingly, we may have to devote a substantial amount of resources to strategic relationships, which could detract from or delay our completion of other important development projects or the development of next generation products and technologies.
 
In general, our customers may cancel or reschedule orders on short notice without incurring significant penalties; therefore, our sales and operating results in any quarter are difficult to forecast.
 
In general, customers may cancel or reschedule orders on short notice without incurring significant penalties. Therefore, cancellations, reductions, or delays of orders from any significant customer could have a material adverse effect on our business, financial condition, and results of operations.
 
In addition, a significant portion of our sales and earnings in any quarter depends upon customer orders for our products that we receive and fulfill in that quarter. Because our expense levels are based in part on our expectations as to future revenue and to a large extent are fixed in the short term, we likely will be unable to adjust spending on a timely basis to compensate for any unexpected shortfall in sales. Accordingly, any significant shortfall of sales in relation to our expectations could hurt our operating results.
 
We are dependent on third-party manufacturing and supply relationships for the majority of our products. Our reliance on third-party foundries and suppliers involves certain risks that may result in increased costs, delays in meeting our customers’ demand, and loss of revenue.
 
We do not own or operate a semiconductor fabrication facility and do not have the resources to manufacture the majority of our products internally. We depend upon third parties to manufacture, assemble, package and test the majority of our products. As a result, we are subject to risks associated with these third parties, including:

 	§   	insufficient capacity available to meet our demand;	
 		
 	§   	inadequate manufacturing yields and excessive costs;	
 		
 	§   	inability of these third-parties to obtain an adequate supply of raw materials;	
 		
 	§   	difficulties selecting and integrating new subcontractors;	
 		
 	§   	limited warranties on products supplied to us;	
 		
 	§   	potential increases in prices; and	
 		
 	§   	increased exposure to potential misappropriation of our intellectual property.	
 
Our outside foundries and assembly and test suppliers generally manufacture our products on a purchase order basis, and we have few long-term supply arrangements with these suppliers. Therefore, our third party manufacturers and suppliers are not obligated to supply us with products for any specific period of time, quantity, or price, except as may be provided in any particular purchase order. A manufacturing or supply disruption experienced by one or more of our outside suppliers or a disruption of our relationship with an outside foundry could negatively impact the production of certain of our products for a substantial period of time.
 
In addition, difficulties associated with adapting our technology and product design to the proprietary process technology and design rules of outside foundries can lead to reduced yields of our products. Since low yields may result from either design or process technology failures, yield problems may not be effectively determined or resolved until an actual product exists that can be analyzed and tested to identify process sensitivities relating to the design rules that are used. As a result, yield problems may not be identified until well into the production process, and resolution of yield problems may require cooperation between us and our manufacturer. This risk could be compounded by the offshore location of certain of our manufacturers,
 
Page 9 of 71

Table of Contents

increasing the effort and time required to identify, communicate and resolve manufacturing yield problems. Manufacturing defects that we do not discover during the manufacturing or testing process may lead to costly product recalls. These risks may lead to increased costs or delayed product delivery, which would harm our profitability and customer relationships.
 
In some cases, our requirements may represent a small portion of the total production of the third-party suppliers. As a result, we are subject to the risk that a producer will cease production of an older or lower-volume process that it uses to produce our parts. We cannot assure you that our external foundries will continue to devote resources to the production of parts for our products or continue to advance the process design technologies on which the manufacturing of our products are based. Each of these events could increase our costs, lower our gross margin, cause us to hold more inventories, or materially impact our ability to deliver our products on time.
 
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.
 
We rely on independent foundries and assembly and test houses to manufacture, or provide components for, our products. Our reliance on these third party suppliers involves certain risks and uncertainties. For example, 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 from our customers. 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, if we experience supply constraints or manufacturing problems at a particular supplier, we could be required to switch suppliers or qualify additional suppliers. Switching and/or qualifying additional suppliers could be an expensive process and take as long as six to twelve months to complete, which could result in material adverse fluctuations to our operating results.
 
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 in the accuracy of our customers’ forecasts, 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.
 
Because we depend on subcontractors internationally to perform key manufacturing functions for us, we are subject to political, economic, and natural disaster risks that could disrupt the fabrication, assembly, packaging, or testing of our products.
 
We depend on third-party subcontractors, primarily in Asia, for the fabrication, assembly, packaging, and testing of most of our products. International operations may be subject to a variety of risks, including political instability, global health conditions, currency controls, exchange rate fluctuations, changes in import/export regulations, tariff and freight rates, as well as the risks of natural disasters such as earthquakes, tsunamis, and floods. Although we seek to reduce our dependence on any one subcontractor, this concentration of subcontractors and manufacturing operations in Asia subjects us to the risks of conducting business internationally, including associated political and economic conditions. If we experience manufacturing problems at a particular location, or a supplier is unable to continue operating due to financial difficulties, natural disasters, or other reasons, we would be required to transfer manufacturing to a backup supplier. Converting or transferring manufacturing from a primary supplier to a backup facility could be expensive and time consuming. As a result, delays in our production or shipping by the parties to whom we outsource these functions could reduce our sales, damage our customer relationships, and damage our reputation in the marketplace, any of which could harm our business, results of operations, and financial condition.
 
Page 10 of 71

Table of Contents

Our sales could be materially impacted by the failure of other component suppliers to deliver required parts needed in the final assembly of our customer’s end products.
 
The products we supply our customers are typically a portion of the many components provided from multiple suppliers in order to complete the final assembly of an end product. If one or more of these other component suppliers are unable to deliver their required component(s) in order for the final product to be assembled, our customer may delay, or ultimately cancel, their orders from us.
 
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 we or our customers or end users could discover latent defects or subtle faults after volumes of product have been shipped. This could result in material costs to us, including, but not limited to:

 	§   	reduced margins;	
 		
 	§   	damage to our reputation;	
 		
 	§   	a material recall and replacement costs for product warranty and support;	
 		
 	§   	payments to our customer related to the 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 or warranty claim brought against us, even if unsuccessful, would likely be time consuming and costly to defend. In particular, the sale of systems and components that are incorporated 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 some of these risks and that we have attempted to contractually limit our financial exposure with many of our customers, a warranty or product liability claim against us in excess of our available insurance coverage and established reserves, or a requirement that we participate in a customer product recall, would have adverse effects (that could be material) on our business, results of operations, and financial condition.
 
Costs related to product defects and errata may harm our results of operations and business.
 
Costs associated with unexpected product defects and errata (deviations from published specifications) due to, for example, unanticipated problems in our design and manufacturing processes, could include:

 	§   	writing off the value of inventory of such products;	
 		
 	§   	disposing of products that cannot be fixed;	
 		
 	§   	recalling such products that have been shipped to customers;	
 		
 	§   	providing product replacements for, or modifications to, such products; and	
 		
 	§   	defending against litigation related to such products.	
 
These costs could be substantial and may increase our expenses and lower our profitability. In addition, our reputation with our customers or users of our products could be damaged as a result of such product defects and errata, and the demand for our products could be reduced. The announcement of product defects
 
Page 11 of 71

Table of Contents

and/or errata could cause customers to purchase products from our competitors as a result of anticipated shortages of our components or for other reasons. These factors could harm our financial results and the prospects for our business.
 
As we carry only limited insurance coverage, any incurred liability resulting from uncovered claims could adversely affect our financial condition and results of operations.
 
Our insurance policies may not be adequate to fully offset losses from covered incidents, and we do not have coverage for certain losses. For example, there is limited coverage available with respect to the services provided by our third party foundries and assembly and test subcontractors. Although we believe that our existing insurance coverage is consistent with common practices of companies in our industry, our insurance coverage may be inadequate to protect us against product recalls, natural disasters, and other unforeseen catastrophes that could adversely affect our financial condition and results of operations.
 
We have historically experienced fluctuations in our operating results and expect these fluctuations to continue in future periods, which may result in volatility in our stock price.
 
Our quarterly and annual operating results are affected by a wide variety of factors that could materially and adversely affect our net sales, gross margin, and operating results. If our operating results fall below expectations of market analysts or investors, the market price of our common stock could decrease significantly. We are subject to business cycles and it is difficult to predict the timing, length, or volatility of these cycles. These business cycles may create pressure on our sales, gross margin, and/or operating results.
 
Factors that could cause fluctuations and materially and adversely affect our net sales, gross margin and operating results include, but are not limited to:

 	§   	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;	
 		
 	§   	excess or obsolete inventory;	
 		
 	§   	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;	
 		
 	§   	reduction of manufacturing yields;	
 		
 	§   	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.	
 
We may be adversely impacted by current global economic conditions. As a result, our financial results and the market price of our common shares may decline.
 
Current global economic conditions could make it difficult for our customers, our suppliers, and us to accurately forecast and plan future business activities, and could cause global businesses to defer or reduce spending on our products, or increase the costs of manufacturing our products. During challenging economic times our customers and distributors may face issues gaining timely access to sufficient credit, which could impact their ability to make timely payments to us. If that were to occur, we may be required to increase our allowance for doubtful accounts and our days sales outstanding would increase.
 
Page 12 of 71

Table of Contents

We cannot predict the timing, strength, or duration of any economic slowdown or subsequent economic recovery. If the economy or markets in which we operate were to deteriorate, our business, financial condition, and results of operations will likely be materially and/or adversely affected.
 
Our results may be affected by the fluctuation in sales in the consumer entertainment market.
 
Because we sell products in the consumer entertainment market, we are likely to be affected by seasonality in the sales of our products. Further, a decline in consumer confidence and consumer spending relating to economic conditions, terrorist attacks, armed conflicts, oil prices, global health conditions, natural disasters, and/or the political stability of countries that we operate in or sell into could have a material adverse effect on our business.
 
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 decline 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 sales shortfalls. Because of these factors, we may experience material adverse fluctuations in our future operating results on a quarterly or annual basis.
 
Our failure to develop and introduce in a timely manner new products that gain market acceptance 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. New product introductions involve significant investment of resources and potential risks. Delays in new product introductions or less-than-anticipated market acceptance of our new products are possible and would have an adverse effect on our sales and earnings. 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, but not limited to:

 	§   	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;	
 		
 	§   	achievement of acceptable manufacturing yields;	
 		
 	§   	availability of wafer fabrication, assembly, and test capacity;	
 		
 	§   	market acceptance of our products and the products of our customers; and	
 		
 	§   	obtaining and retaining industry certification requirements.	
 
Both sales and margins may be materially affected if new product introductions are delayed, or if our products are not designed into successive generations of new or existing customers’ products. We may not 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.
 
Page 13 of 71

Table of Contents

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 provide assurances that we will be able to successfully develop and introduce new products on a timely 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 represented 82 percent, 79 percent, and 68 percent of our net sales in fiscal years 2011, 2010, and 2009, respectively. We expect export sales to continue to represent a significant portion of product sales. This reliance on international sales subjects us to the risks of conducting business internationally, including risks associated with political and economic 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, especially in Asia. For example, the financial instability in a given region 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, but not limited to:

 	§   	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 non-U.S. companies or other domestic companies entering the non-U.S. 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 non-U.S. 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 non-U.S. 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 provide assurances that regulatory, political and other factors will not adversely affect our operations in the future or require us to modify our current business practices.
 
We are subject to the export control regulations of the U.S. Department of State and the Department of Commerce. A violation of these export control regulations could have a material adverse effect on our business or our results of operations, cash flows, or financial position.
 
The nature of our international business, and in particular, the manufacture and sale of certain products from our Apex Precision Power Product line, subjects us to the export control regulations of the U.S. Department of State and the Department of Commerce. If these export control regulations are violated, it could result in monetary penalties and denial of export privileges. The government is very strict with respect to compliance and has served notice generally that failure to comply with these regulations may subject guilty parties to fines and/or imprisonment. Although we are not aware of any material violation of any export control regulations, a failure to comply with any of the above mentioned regulations could have a material adverse effect on our business.

Table of Contents

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 large portion of our net sales, we maintain international operations, sales, and technical support personnel. International expansion has required, and will continue to require, significant management attention and resources. There are risks inherent in expanding our presence into non-U.S. regions, including, but not limited to:

 	§   	difficulties in staffing and managing non-U.S. operations;	
 		
 	§   	failure of non-U.S. 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;	
 		
 	§   	vulnerability to terrorist groups targeting American interests abroad; and	
 		
 	§   	legal uncertainty regarding liability and compliance with non-U.S. laws and regulatory requirements.	
 
If we are unable to successfully manage the demands of our international operations, it may have a material adverse effect on our business, financial condition, or results of operations.
 
Our failure to manage our distribution channel relationships could adversely affect our business.
 
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.
 
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, 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 margin 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 Semiconductor Inc., Analog Devices Inc., Austriamicrosystems AG, Freescale Semiconductor Inc., Integrated Device Technology Inc., iWatt Inc., Infineon Technologies AG, Linear Technologies Corporation, Maxim Integrated Products Inc., NXP Semiconductors N.V., ON Semiconductor Corporation, Power Integrations Inc., Realtek Semiconductor Corporation, ST Microelectronics N.V., Texas Instruments, Inc., and Wolfson Microelectronics plc. Many of these competitors have greater financial, engineering, manufacturing, marketing, technical, distribution, and other resources; broader product lines; broader intellectual property portfolios; 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 provide assurances 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.

Table of Contents

We may be unable to protect our intellectual property rights.
 
Our success depends in part on our ability to obtain patents and to preserve our other intellectual property rights covering our products. 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 on trade secrets, proprietary technology, non-disclosure and other contractual terms, 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 provide assurances that steps taken by us to protect our intellectual property will be adequate, that our competitors will not independently develop or design around our patents, or that our intellectual property will not be misappropriated. In addition, the laws of some non-U.S. countries may not protect our intellectual property as well as the laws of the United States.
 
Any of these events could materially and adversely affect our business, operating results, and financial condition. Policing infringement of our technology is difficult, and litigation may be necessary in the future to enforce our intellectual property rights. Any such litigation could be expensive, take significant time, and divert management’s attention from other business concerns.
 
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 provide assurances that we will ultimately be successful in any lawsuit, nor can we provide assurances that any patent owned by us will not be invalidated, circumvented, or challenged. We cannot provide assurances that rights granted under our patents 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 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 highly qualified 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. 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 may acquire other companies or technologies, which may create additional risks associated with our ability to 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. If we are able to acquire companies, products or technologies that would enhance our business, we could experience
 
Page 16 of 71

Table of Contents

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 strategic and operational issues;	
 		
 	§   	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.
 
Future transactions may limit our ability to use our net operating loss carryforwards.
 
As of March 26, 2011, we had U.S. federal tax net operating loss (“NOL”) carryforwards of approximately $423.7 million. These NOL carryforwards may be used to offset future taxable income and thereby reduce our U.S. federal income taxes otherwise payable. There is a risk we may not be able to generate taxable income in the future in the amount necessary to fully utilize all of these NOLs. Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), imposes an annual limit on the ability of a corporation that undergoes an “ownership change” to use its NOL carry forwards to reduce its tax liability. If we were at some point in the future to experience an “ownership change” as defined in Section 382 of the Code, our use of the net operating loss carryforwards and credit carryforwards may be limited as described in the Code.
 
Our financial results may be adversely affected by changes in the valuation allowance on our deferred tax assets.
 
The Company has a significant amount of deferred tax assets. Our ability to recognize these deferred tax assets is dependent upon our ability to determine whether it is more likely than not that we will be able to realize, or actually use, these deferred tax assets. That determination depends primarily on our ability to generate future U.S. taxable income. Our judgments regarding future profitability may change due to future market conditions, changes in U.S. or international tax laws and other factors. These changes, if any, may require possible material adjustments to the net deferred tax asset and an accompanying reduction or increase in net income in the period in which such determinations are made.
 
Our stock price has been and is likely to continue to be volatile.
 
The market price of our common stock fluctuates significantly. This fluctuation has been or may be the result of numerous factors, including, but not limited to:

 	§   	actual or anticipated fluctuations in our operating results;	
 		
 	§   	announcements concerning our business or those of our competitors, customers, or suppliers;	
 		
 	§   	loss of a significant customer, or customers;	
 		
 	§   	changes in financial estimates by securities analysts or our failure to perform as anticipated by the analysts;	
 
Page 17 of 71

Table of Contents

			
 	§   	news, commentary, and rumors emanating from the media relating to us, our customers, or the industry. These reports may be unrelated to the actual operating performance of the company, and in some cases, may be potentially misleading or incorrect;	
 		
 	§   	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 stockholders selling for any reason;	
 		
 	§   	general conditions in the IC industry; and	
 		
 	§   	general market conditions and interest rates.	
 
We have provisions in our certification of incorporation and Bylaws, 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 Delaware law and of our Certificate of Incorporation and Bylaws could make it more difficult for a third party to acquire us, even if our stockholders support the acquisition. These provisions include, but are not limited to:

 	§   	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.
 
We are subject to the risks of owning real property.
 
We have purchased land for the purpose of building our U.S. headquarters in Austin, Texas, and we own our facility in Tucson, Arizona. The purchase of land and the current construction of our U.S. headquarters, along with the ownership of our facility in Tucson, subject us to the risks of owning real property, which may include:

 	§   	the possibility of environmental contamination and the costs associated with correcting any environmental problems;	
 		
 	§   	adverse changes in the value of these properties, due to interest rate changes, changes in the neighborhood in which the property is located, or other factors;	
 		
 	§   	increased cash commitments for constructing a new building in Austin, Texas, or improving the current building and property in Tucson, Arizona; and	
 		
 	§   	the risk of financial loss in excess of amounts covered by insurance, or uninsured risks, such as the loss caused by damage to the buildings as a result of fire, floods, or other natural disasters.

ITEM 2.  	Properties	
 
As of May 1, 2011, our principal leased facilities, located in Austin, Texas, consisted of approximately 214,000 square feet of office space. This leased space includes our headquarters and engineering facility, which has 197,000 square feet with lease terms that extend into the summer of calendar year 2012, excluding lease extension options, and 17,000 square feet of leased space at our failure analysis facility with lease terms that extend into calendar year 2013. We have subleased approximately 38,000 square feet of space at our Austin headquarters with sublease terms that extend into the summer of calendar year 2012. In addition, we own an engineering, administrative, and assembly facility in Tucson, Arizona, which primarily houses employees who design, manufacture, and sell the Apex brand of products.
 
In February 2011, the Company commenced construction of its future corporate headquarters in Austin, Texas. We anticipate completing the construction of the facility in the summer of calendar year 2012, at which time we expect to relocate our Austin employees from their current leased facilities. The new headquarters facility will consist of approximately 135,000 square feet of office space, and the Company will be the sole occupant of this new office space.
 
In September 2010, the lease for our former design facility in Boulder, Colorado terminated. The Company did not renew this lease agreement.
 
We do not anticipate difficulty in either retaining occupancy at any of our facilities through lease renewals prior to expiration or replacing them with equivalent facilities, and we believe that our existing facilities are suitable and adequate for our present purposes.
 
Below is a detailed schedule that identifies our occupied leased and owned property locations as of May 1, 2011, with various lease terms through fiscal year 2014:

Design Centers	 	Sales Support Offices – USA	 	Sales Support Offices – International

ITEM 3.  	Legal Proceedings	
 
As of the balance sheet date, to the best of our knowledge, the Company is not a party to any material pending litigation. From time to time, 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 our industry. As to any of these potential claims or litigation, we cannot predict the ultimate outcome with certainty.

Overview
 
We were incorporated in California in 1984, became a public company in 1989, and were reincorporated in the State of Delaware in February 1999. Initially, our focus was on providing ICs for personal computer applications, including personal computer (“PC”) graphics and storage. In 2001, 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 reinforced our commitment to operate efficiently and profitably by taking strategic actions beginning in 2005 to improve our top and bottom line growth, including: (1) improving efficiencies by focusing on our mixed-signal audio and energy product lines, (2) divesting our digital video product line assets and non-core products to focus on our core strengths, and (3) enhancing our capital structure by completing a $150 million stock repurchase program in fiscal year 2009 to increase long-term stockholder value. We continued this process in fiscal years 2010 and 2011 by focusing on winning new designs, growing our market share in portable audio products in particular, completing another $20 million stock repurchase program, announcing another $80 million stock buyback, and by laying the foundation for growth in our energy products.
 
Fiscal Year 2011
 
In fiscal year 2011 we continued our strategy of targeting and developing relationships with Tier 1 customers in growing markets, such as portable audio products, including smartphones; automobile audio amplifiers; and energy measurement and energy control. We build on our diverse analog and signal-processing patent portfolio by delivering highly optimized products for a variety of audio and energy-related applications. While we dedicate substantial resources and investments towards portable audio products, we are also investing in energy-related applications. Our current investments in the Energy product lines are focused on energy measurement and the energy control areas such as power factor correction, motor control, and lighting. We have received our first digital LED lighting controller back from the fab, and have a Tier 1 customer currently evaluating the use of this device.
 
Fiscal year 2011 net sales of $369.6 million represented a 67 percent increase over fiscal year 2010 net sales of $221.0 million. Audio product line sales of $264.8 million in fiscal year 2011 represented a 72 percent increase over fiscal year 2010 sales of $153.7 million, and were primarily attributable to higher sales of portable audio and surround codec products. Energy product line sales of $104.7 million in fiscal year 2011 represented a 56 percent increase over fiscal year 2010 sales of $67.3 million, and were primarily attributable to higher seismic, power meter, and power amplification products.
 
Overall gross margin of 54.7 percent for fiscal year 2011 reflects an increase from fiscal year 2010 margin of 53.7 percent due to enhanced supply chain management, activity within the energy product line, and in particular to the sales of seismic, power meter, and power amplification products.
 
With expanding design win opportunities in both our audio and energy product lines, the Company continued to take advantage of the availability of engineering talent, which resulted in an increase of 64 research and development employees, or 26 percent, as compared to the end of fiscal year 2010.
 
The Company achieved net income of $203.5 million in fiscal year 2011, which included a benefit for income taxes in the amount of $119.3 million as a result of the realization of an additional $120.0 million of net deferred tax assets. Finally, the Company’s cash, cash equivalents and investments balances as of March 26, 2011, of $215.1 million reflects an increase of $73.5 million, or 52 percent, over the ending balances from the prior fiscal year.
 
Fiscal Year 2010
 
Fiscal year 2010 net sales of $221 million represented a 27 percent increase over fiscal year 2009 net sales of $174.6 million. Increased sales from our audio product line, in particular portable audio and surround codec products, were key drivers in the overall improvement in top-line revenues in fiscal year 2010 versus the prior fiscal year.

Table of Contents

While fiscal year 2010 net sales from our energy product line reflected a net 13 percent reduction from fiscal year 2009 results, the energy product line ended its fiscal year on a positive note with increased sales of seismic and power meter products, as well as improved performance from ARM and communication products. We saw improvements in a variety of our energy product lines throughout fiscal year 2010, as our traditional industrial business benefitted from the improving economy. Seismic product sales were down from prior year peak levels, although they improved sequentially throughout fiscal year 2010.
 
Overall gross margin of 53.7 percent for fiscal year 2010 reflected a decrease from fiscal year 2009 margin of 55.6 percent due to the recent growth in sales of portable audio products, as well as a mix change to lower margin products in our energy product line driven primarily by a reduction in seismic product sales in fiscal year 2010. The Company achieved net income of $38.4 million in fiscal year 2010, which included an $11.9 million recognition of deferred tax assets. The $38.4 million of net income in fiscal year 2010 represented an increase of $34.9 million over fiscal year 2009 net income of $3.5 million. Finally, the Company’s cash, cash equivalents and investments balances as of March 27, 2010, of $141.6 million reflects an increase of $21.4 million over the ending balances from the prior fiscal year.
 
Fiscal Year 2009
 
For fiscal year 2009, net sales were down approximately 4 percent from the preceding year. However, our strength in revenue from new products and prudent expense management were key drivers in the Company maintaining bottom-line profitability for the year as a whole while establishing a solid base for future growth.

Net Sales
 
We report sales in two product categories: audio products and energy products. Our sales by product line are as follows (in thousands):

 	 	March 26,	 	 	March 27,	 	 	March 28,	 	
 	 	2011	 	 	2010	 	 	2009	 	
 		
Audio products	 	$	264,840	 	 	$	153,661	 	 	$	97,293	 	
Energy products	 	 	104,731	 	 	 	67,328	 	 	 	77,349	 	
 	 	 	 	 	 	 	 	 	 	 	 	 	
Total	 	$	 369,571	 	 	$	 220,989	 	 	$	 174,642	 	

 
Net sales for fiscal year 2011 increased 67 percent, to $369.6 million from $221.0 million in fiscal year 2010. The increase in net sales reflects a $111.2 million increase in audio product sales and a $37.4 million increase in energy product sales. The audio products group experienced growth primarily from the sales of portable and surround codecs products, while the energy product group sales increases were primarily attributable to sales of seismic, power meter, and power amplification products.
 
Net sales for fiscal year 2010 increased 27 percent, to $221.0 million from $174.6 million in fiscal year 2009. The increase in net sales reflects a $56.4 million increase in audio product sales and a $10.0 million decrease in energy product sales. The audio products group experienced growth from the sales of portable and surround codecs products, which were partially offset by decreases in ADC and interface product sales. Within the energy product group, sales decreases were primarily attributable to lower sales of seismic, communications, and ARM processor-based products. These decreases were partially offset by an increase in power meter products sales.
 
Export sales, principally to Asia, including sales to U.S.-based customers that manufacture products at plants overseas, were approximately $302.7 million in fiscal year 2011, $173.6 million in fiscal year 2010, and $119.5 million in fiscal year 2009. Export sales to customers located in Asia were 70 percent, 65 percent, and 48 percent of net sales in fiscal years 2011, 2010, and 2009, respectively. All other export sales represented 12 percent, 14 percent, and 20 percent of net sales in fiscal years 2011, 2010, and 2009, respectively.
 
Our sales are denominated primarily in U.S. dollars. During fiscal years 2011, 2010, and 2009, we did not enter into any foreign currency hedging contracts.
 
Gross Margin
 
Overall gross margin of 54.7 percent for fiscal year 2011 reflects an increase from fiscal year 2010 margin of 53.7 percent, primarily due to enhanced supply chain management, sales activity within the energy product line, and in particular to the sales of seismic, power meter, and power amplification products. The sale of product written down in prior fiscal years contributed approximately $1.5 million, or 0.4 percent, to gross margin compared to approximately $1.3 million, or 0.6 percent, in fiscal year 2010. In total, excess and obsolete inventory charges, including scrapped inventory, increased by $5.1 million from fiscal year 2010 and resulted in a decrease of gross margin by 1.4 percent. The $5.1 million increase in excess and obsolete inventory charges was primarily attributable to a charge of approximately $4.2 million in the fourth quarter of the Company’s current fiscal year due to a production issue with a new audio device that entered high volume production in March 2011.
 
Gross margin was 54 percent in fiscal year 2010, down from 56 percent in fiscal year 2009. The decrease in margin from fiscal year 2009 was mainly due to changes in both customer and product mix. While the audio product group experienced a slight increase in margin from fiscal year 2009 to fiscal year 2010 and the energy group margins were essentially unchanged for this comparable period, the increase in the percentage of sales from the audio group in fiscal year 2010 caused a net reduction in overall margins. The sale of product that had been written down in prior fiscal years contributed approximately $1.3 million, or 0.6 percent, to gross margin compared to a contribution of approximately $1.6 million, or 0.9 percent, in fiscal year 2009. In total, excess and obsolete inventory charges increased by $0.6 million from fiscal year 2009, which resulted in a decrease in gross margin by 0.3 percent.

Research and Development Expenses
 
Fiscal year 2011 research and development expenses of $63.9 million reflect an increase of $12.5 million, or 24 percent, from fiscal year 2010. The variance was primarily due to a 26 percent increase in research and development headcount and associated employee expenses, including variable compensation attributable to improved operating profit. Additionally, employment expenses also increased primarily due to contract labor costs and employee hiring related expenses.
 
Fiscal year 2010 research and development expenses of $51.4 million reflect an increase of $7.1 million, or 16 percent, from fiscal year 2009. The increase was primarily due to $3.5 million in salary and benefit costs associated with research and development personnel, whose headcount increased 12 percent in fiscal year 2010 as compared to fiscal year 2009. Additionally, product development expenses increased $2.8 million, primarily due to higher photo-mask expenses. These increases in research and development expenses were partially offset by non-recurring engineering work performed and billed to third parties, which resulted in a $0.6 million reduction in research and development expenses.
 
Selling, General and Administrative Expenses
 
Fiscal year 2011 selling, general and administrative expenses of $58.1 million reflect an increase of $12.1 million, or 26 percent, compared to fiscal year 2010. The $12.1 million increase was primarily attributable to increased variable compensation costs driven by improved operating profit, as well as to higher stock option expenses and external sales representative commissions. The number of employees in the selling, general, and administrative expense category remained essentially unchanged from the end of fiscal year 2010.
 
Fiscal year 2010 selling, general and administrative expenses of $45.9 million reflect an increase of $0.6 million, or 1 percent, compared to fiscal year 2009 as an increase in salaries and benefits costs was offset by decreased expenses across several expense categories. A $2.3 million increase in salaries and benefits costs was primarily attributable to increased headcount, and also due to higher sales commissions brought on by increased product sales and fluctuations in commissionable product mix in fiscal year 2010 versus fiscal year 2009. Offsetting this increase was a $0.6 million reduction in net rent expenses, a $0.6 decrease in marketing expenses, and a $0.5 million reduction in professional expenses.
 
Restructuring Costs and Other, net
 
During fiscal year 2010, we recorded net restructuring charges of $0.5 million as a separate line item on the statement of operations in operating expenses under the caption “Restructuring costs and other, net.” The restructuring charge was primarily due to revised sublease assumptions for lease space within our corporate headquarters building.
 
As of March 26, 2011, we have a remaining restructuring accrual for all of our past restructurings of $0.4 million, primarily related to future lease payments net of anticipated subleases that will be paid over the respective lease terms through the summer of calendar year 2012. We have classified $0.1 million of this restructuring accrual as long-term.
 
Impairment of (Proceeds From) Non-Marketable Securities
 
In the second quarter of the current fiscal year, the Company recognized a loss on the impairment of an equity investment in the amount of $0.5 million. Our original investment was in the form of a note receivable, which was then converted into an equity security during the second quarter of the current fiscal year. After the conversion, we determined that an impairment indicator existed related to our cost method investment. We performed a fair value analysis of our cost method investment in accordance with FASB ASC Topic 320 — “Investments — Debt and Equity Securities.” Based on the results of this analysis as of September 25, 2010, we recognized an impairment of $0.5 million to reduce the carrying value of the cost method investment to zero. The impairment was recorded as a separate line item on the consolidated statement of operations in operating expenses under the caption “Impairment of (proceeds from) non-marketable securities.”

In the third quarter of fiscal year 2010, as part of a convertible note financing round for Magnum Semiconductor, Inc. (“Magnum”), a company that we had previously had an investment in, we received proceeds of $500 thousand from Magnum as consideration for our ownership interest in Magnum securities, which in fiscal year 2008 had previously been fully impaired. The proceeds were recorded as a separate line item on the consolidated statement of operations in operating expenses under the caption “Impairment of (proceeds from) non-marketable securities.”
 
Provision (Benefit) For Litigation Expenses and Settlements
 
During the fourth quarter of the current fiscal year, in response to certain patent infringement allegations, the Company incurred $57 thousand as part of the execution of a Settlement and License Agreement. During the third quarter of fiscal year 2011, the Company received proceeds of $113 thousand reflecting the final resolution of litigation with Silvaco Data Systems. Of this amount, $30 thousand represented the settlement awarded to the Company, and the balance represented recoveries of certain litigation expenses and interest. Finally, during the first quarter of fiscal year 2011, the Company incurred $135 thousand in settlement costs related to a dispute with a former distributor of the Company’s products. These transactions, in the cumulative net amount of $162 thousand, are reflected as a separate line item on the consolidated statement of operations in operating expenses under the caption “Provision (benefit) for litigation expenses and settlements.”
 
On March 23, 2009, a lawsuit was filed against the Company alleging patent infringement. During the third quarter of fiscal year 2010, a settlement agreement was concluded which resulted in Cirrus Logic recognizing a $135 thousand charge related to the suit. In a separate matter, on June 17, 2009, during the first quarter of fiscal year 2010, the Company received proceeds of a net $2.7 million from its insurance carrier as part of the final settlement of litigation where a purported stockholder filed a derivative lawsuit in the state district court in Travis county, Texas against current and former officers and directors of the Company related to certain prior grants of stock options by the Company. The proceeds of $2.7 million were recorded as a recovery of costs previously incurred in accordance with FASB ASC Topic 450, “ Contingencies. ” The combined net amount of $2.6 million from these two fiscal year 2010 transactions are reflected as a separate line item on the consolidated statement of operations in operating expenses under the caption “Provision (benefit) for litigation expenses and settlements.”
 
During fiscal year 2009, we recognized a $2.2 million charge related to legal fees and expenses associated with the derivative lawsuits. The charge was recorded as a separate line item on the consolidated statement of operations in operating expenses under the caption “ Provision (benefit) for litigation expenses and settlements. ”
 
Patent Agreement, Net
 
On July 13, 2010, we entered into a Patent Purchase Agreement for the sale of certain Company owned patents. As a result of this agreement, on August 31, 2010, the Company received cash consideration of $4.0 million from the purchaser. The proceeds were recorded as a recovery of costs previously incurred and are reflected as a separate line item on the consolidated statement of operations in operating expenses under the caption “Patent agreement, net.”
 
On June 11, 2009, we entered into a Patent Purchase Agreement for the sale of certain Company owned patents and on August 26, 2009, the Company received cash consideration of $1.4 million from the purchaser. The proceeds were recorded as a recovery of costs previously incurred and are reflected as a separate line item on the consolidated statement of operations in operating expenses under the caption “Patent agreement, net.”
 
Impairment of Intangible Assets
 
In the fourth quarter of fiscal year 2009, we noted several impairment indicators surrounding patents that we acquired in June 2007. We performed an impairment analysis under FASB ASC Topic 360 “Property, Plant, and Equipment,” and noted that the undiscounted cash flows estimated to be generated from these patents were less than the carrying amount of the assets. We then compared the estimated fair value of these

assets to their carrying amount and recognized an impairment loss of $2.1 million. The impairment was recorded as a separate line item on the consolidated statement of operations in operating expenses under the caption “Impairment of intangible assets.”
 
Interest Income
 
Interest income in fiscal years 2011, 2010, and 2009, was $0.9 million, $1.3 million, and $2.8 million respectively. The decrease in interest income in fiscal year 2011 compared to fiscal year 2010, as well as for fiscal year 2010 as compared to fiscal year 2009, was attributable to lower yields on invested capital.
 
Income Taxes
 
We recorded an income tax benefit of $119.3 million in fiscal year 2011 on a pre-tax income of $84.2 million, yielding an effective tax benefit rate of 142 percent. Our effective tax rate was lower than the U.S. statutory rate of 35 percent, primarily as a result of the release of a portion of the valuation allowance on certain deferred tax assets that have not yet been utilized. The release of a portion of the valuation allowance generated a $120.0 million tax benefit and was based on an evaluation of the net U.S. deferred tax assets that we expect are more likely than not to be utilized in the upcoming years as a result of projected net income.
 
We recorded an income tax benefit of $11.7 million in fiscal year 2010 on a pre-tax income of $26.7 million, yielding an effective tax benefit rate of 44 percent. Our effective tax rate was lower than the U.S. statutory rate of 35 percent, primarily as a result of the realization of deferred tax assets that had been fully reserved and the release of a portion of the valuation allowance on certain deferred tax assets that have not yet been utilized. The release of a portion of the valuation allowance generated an $11.8 million tax benefit and was based on an evaluation of the net U.S. deferred tax assets that we expect to utilize in the upcoming year as a result of projected tax basis net income.
 
We recorded an income tax provision of $2.7 million in fiscal year 2009 on a pre-tax income of $6.2 million, yielding an effective tax rate of 44 percent. Our effective tax rate was higher than the U.S. statutory rate of 35 percent primarily due to a $2.7 million charge to tax expense to increase the valuation allowance on our U.S. deferred tax assets.
 
We evaluate our ability to realize our deferred tax assets on a quarterly basis. We have deferred tax assets generated in non-U.S. jurisdictions that we have recognized since it is more likely than not that these assets will be realized.
 
Outlook
 
Based on our strategic plan, our long-term business model targets for the Company are annual revenue growth of 15 percent, gross margins of 55 percent, and operating profit of 20 percent. In fiscal year 2012, we anticipate revenue growth below this target in the first two quarters, with stronger revenue growth in the second half of the fiscal year when new product introductions from multiple customers begin shipping in full production.
 
Liquidity and Capital Resources
 
In fiscal year 2011, our net cash provided by operating activities was $86.9 million. The positive cash flow from operating activities was predominantly due to the cash components of our net income, which were partially offset by a $12.8 million reduction in working capital. In fiscal year 2010, our operating activities generated $25.1 million in cash. The positive cash flow from operating activities was predominantly due to the cash components of our net income, which were partially offset by a $14.0 million decrease in working capital. In fiscal year 2009, our operating activities generated $23.1 million in cash. The positive cash flow from operating activities was predominantly due to the cash components of our net income coupled with a $2.3 million increase in working capital.
 
In fiscal year 2011, we used approximately $74.2 million in cash from investing activities, principally due to the net purchase of $52.7 million in marketable securities. In addition, during fiscal year 2011, we invested
 
Page 28 of 71

Table of Contents

$20.1 million in property, equipment, and capitalized software, primarily attributable to the purchase of land for our new corporate headquarters in the amount of $10.8 million, coupled with $2.4 million in headquarters construction costs. During fiscal year 2011, we also incurred $1.5 million for investments in technology. In fiscal year 2010, we used approximately $42.6 million in cash from investing activities, principally due to the net purchase of $36.8 million in marketable securities. In addition, during fiscal year 2010, we invested $3.7 million in property, equipment, and capitalized software and $2.2 million in technology. In fiscal year 2009, we generated approximately $36.5 million in cash from investing activities, principally due to the net sale of $41.8 million in marketable securities. In addition, during fiscal year 2009, we invested $3.1 million in property, equipment, and capitalized software and $2.1 million in technology.
 
During fiscal years 2011, 2010, and 2009, we generated $31.0 million, $2.0 million and $2.6 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, in fiscal year 2009, our employee stock purchase plan. In fiscal years 2011 and 2009, the Company utilized approximately $22.8 million and $87.2 million in cash, respectively, to repurchase and retire portions of its outstanding common stock, as previously discussed in Part II — Item 5 — Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities .
 
As of March 26, 2011, we had restricted investments of $5.8 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 cash restriction for this lease agreement is reduced to $2.6 million in September 2011 and expires in May 2012.
 
As of March 26, 2011 the Company has no debt arrangements.
 
The Company has commenced construction of our planned new headquarters facility in Austin, Texas with completion expected in the summer of calendar year 2012. We estimate that as of March 26, 2011 the remaining facility construction costs will be approximately $30 million and will generally occur ratably throughout the construction process. In addition, we estimate that we will incur an additional $9 million in furniture, fixtures, and equipment in order to fully move our headquarters employees into this new facility. It is anticipated that the project will be funded internally from existing and future cash flows.
 
Although we cannot provide assurances to 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
 
As of March 26, 2011, the Company did not have any material off-balance-sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Recently Issued Accounting Pronouncements
 
In January 2010, the FASB issued Accounting Standards Update (“ASU”) No. 2010-06, “Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements” (“ASU 2010-06”), which amends the disclosure guidance with respect to fair value measurements. Specifically, the new guidance requires disclosure of amounts transferred in and out of Levels 1 and 2 fair value measurements, a reconciliation presented on a gross basis rather than a net basis of activity in Level 3 fair value measurements, greater disaggregation of the assets and liabilities for which fair value measurements are presented and more robust disclosure of the valuation techniques and inputs used to measure Level 2 and 3 fair value measurements. ASU 2010-06 was effective for interim and annual reporting periods beginning after December 15, 2009, with the exception of the new guidance around the Level 3 activity reconciliations, which is effective for fiscal years beginning after December 15, 2010. The adoption of this pronouncement did not have a material impact on our consolidated financial statements.
 
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 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 believe the following critical accounting policies involve significant judgments and estimates that are used in the preparation of the consolidated financial statements:

 	§   	For purposes of determining the variables used in the calculation of stock compensation expense for stock options under the provisions of FASB ASC Topic 505, “ Equity ” and FASB ASC Topic 718, “ Compensation — Stock Compensation,” we perform an analysis of current market data and historical company data to calculate an estimate of implied volatility, the expected term of the option, and the expected forfeiture rate. With the exception of the expected forfeiture rate, which is not an input, we

 		use these estimates as variables in the Black-Scholes option pricing model. Depending upon the number of stock options granted, any fluctuations in these calculations could have a material effect on the results presented in our Consolidated Statement of Operations. In addition, any differences between estimated forfeitures and actual forfeitures could also have a material impact on our financial statements.	

 	§   	We recognize revenue in accordance with ASC Topic 605, “ Revenue Recognition,” when all of the following criteria are met: persuasive evidence that an arrangement exists, delivery of goods has occurred, the sales price is fixed or determinable and collectability is reasonably assured. We evaluate our distributor arrangements, on a distributor by distributor basis, with respect to each of the four criteria above. For a majority of our distributor arrangements, we provide rights of price protection and stock rotation. As a result, revenue is deferred at the time of shipment to our domestic distributors and certain international distributors due to the determination that the ultimate sales price to the distributor is not fixed or determinable. Once the distributor has resold the product, and our final sales price is fixed or determinable, we recognize revenue for the final sales price and record the related costs of sales. For certain of our smaller international distributors, we do not grant price protection rights and provide minimal stock rotation rights. For these distributors, revenue is recognized upon delivery to the distributor, less an allowance for estimated returns, as the revenue recognition criteria have been met upon shipment.	
 
Further, the Company defers the associated cost of goods sold on our consolidated balance sheet, net within the deferred income on shipments to distributors’ current liability caption. The Company routinely evaluates the products held by our distributors for impairment to the extent such products may be returned by the distributor within these limited rights and such products would be considered excess or obsolete if included within our own inventory. Products returned by distributors and subsequently scrapped have historically been immaterial to the Company. We believe this treatment is in accordance with ASC Topic 330-10-35, “ Inventory .”

 	§   	The Company evaluates accounts receivable in accordance with FASB ASC Topic 310, “ Receivables.” 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 — Accounts Receivable, net of the Notes to Consolidated Financial Statements contained in Item 8.	
 		
 	§   	The Company evaluates inventory in accordance with FASB ASC Topic 330, “ Inventory.” 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. See Note 2 — Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements contained in Item 8.	
 		
 	§   	We evaluate the recoverability of property, plant, and equipment and intangible assets in accordance with FASB ASC Topic 360, “ Property, Plant, and Equipment ,” and FASB ASC Topic 350, “ Intangibles — Goodwill and Other. ” 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	
 
Page 31 of 71

Table of Contents

			
 		could have a material effect on our operating results and financial position. See Note 7 — Intangibles, net of the Notes to Consolidated Financial Statements contained in Item 8.	

 	§   	The Company evaluates goodwill and other intangible assets in accordance with FASB ASC Topic 350, “ Intangibles — Goodwill and Other.” Goodwill is recorded at the time of an acquisition and is calculated as the difference between the total consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. Accounting for acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the fair value of the net tangible and intangible assets acquired, including in-process research and development (“IPR&D”). Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to annual impairment tests. If the assumptions and estimates used to allocate the purchase price are not correct, or if business conditions change, purchase price adjustments or future asset impairment charges could be required. The value of our intangible assets, including goodwill, could be impacted by future adverse changes such as: (i) any future declines in our operating results, (ii) a decline in the valuation of technology company stocks, including the valuation of our common stock, (iii) a significant slowdown in the worldwide economy and the semiconductor industry, or (iv) any failure to meet the performance projections included in our forecasts of future operating results. In accordance with FASB ASC Topic 350, the Company tests goodwill for impairment on an annual basis or more frequently if the Company believes indicators of impairment exist. Impairment evaluations involve management estimates of asset useful lives and future cash flows. Significant management judgment is required in the forecasts of future operating results that are used in the evaluations. It is possible, however, that the plans and estimates used may be incorrect. If our actual results, or the plans and estimates used in future impairment analysis, are lower than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges in a future period.	
 		
 	§   	Our available-for-sale investments, non-marketable securities and other investments are subject to a periodic impairment review pursuant to FASB ASC Topic 320, “ Investments — Debt and Equity Securities. ” Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. This determination requires significant judgment and actual results may be materially different than our estimate. Marketable securities are evaluated for impairment if the decline in fair value below cost basis is significant and/or has lasted for an extended period of time. Non-marketable securities or other investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. For investments accounted for using the cost method of accounting, we evaluate information (e.g., budgets, business plans, financial statements) in addition to quoted market prices, if any, in determining whether an other-than-temporary decline in value exists. Factors indicative of an other-than-temporary decline include recurring operating losses, credit defaults, and subsequent rounds of financings at an amount below the cost basis of the investment. This list is not all inclusive and we weigh all quantitative and qualitative factors in determining if an other-than-temporary decline in value of an investment has occurred. When a decline in value is deemed to be other-than-temporary, we recognize an impairment loss in the current period’s operating results to the extent of the decline. Actual values could be different from those estimated by management, which could have a material effect on our operating results and financial position. See Note 3 — Marketable Securities and Note 5 — Non-Marketable Securities of the Notes to Consolidated Financial Statements contained in Item 8.	
 		
 	§   	In accordance with Statement of FASB ASC Topic 740, “ Income Taxes,” we provide for the recognition of deferred tax assets if realization of such assets is more likely than not. The Company evaluates the ability to realize its deferred tax assets by using a three year forecast to determine the amount of net operating losses and other deferred tax assets that would be utilized if we achieved the results set forth in the three year forecast. The Company limited the forecast period to three years because of the cyclical and competitive nature of the semiconductor industry, and the Company’s reliance on a key customer who accounted for approximately 47 percent of total sales in fiscal year 2011. There can be no assurance that we will achieve the results set forth in our three year forecast and our actual results may differ materially from our forecast.

We have provided a valuation allowance against a portion of our net U.S. deferred tax assets due to uncertainties regarding their realization. We evaluate our ability to realize our deferred tax assets basis by determining whether or not the anticipated future taxable income is expected to be sufficient to utilize the deferred tax assets that we have recognized. If our future income is not sufficient to utilize the deferred tax assets that we have recognized, we increase the valuation allowance to the point at which all of the remaining recognized deferred tax assets will be utilized by the future taxable income. If our anticipated future taxable income is sufficient to conclude that additional deferred tax assets should be recognized, we decrease the valuation allowance. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax rules and the potential for future adjustment of our uncertain tax positions by the internal revenue service or other taxing jurisdiction. If our estimates of these taxes are greater or less than actual results, an additional tax benefit or charge will result. See Note 15 — Income Taxes of the Notes to Consolidated Financial Statements contained in Item 8.

 	§   	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 FASB ASC Topic 420, “ Exit or Disposal Cost Obligations. ” We use an estimated borrowing rate as the discount rate for all of our restructuring accruals made under FASB ASC Topic 420. Our facilities consolidation accruals are 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 — Restructuring Costs and Other of the Notes to Consolidated Financial Statements contained in Item 8.	
 		
 	§   	We are subject to the possibility of loss contingencies for various legal matters. See Note 9 — Legal Matters of the Notes to Consolidated Financial Statements contained in Item 8 . 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, currency movements on non-U.S. dollar denominated assets and liabilities, and the effect of market factors on the value of our non-marketable equity securities. We assess these risks on a regular basis and have established policies that are designed to protect against the adverse effects of these and other potential exposures. All of the potential changes noted below are based on sensitivity analyses as of March 26, 2011. Actual results may differ materially.
 
Interest Rate Risk
 
Our primary financial instruments include cash and cash equivalents, marketable securities, accounts receivable, accounts payable, and accrued liabilities. The Company’s investments are managed by outside professional managers within investment guidelines set by the Company. These guidelines include security type, credit quality, and maturity, and are intended to limit market risk by restricting the Company’s investments to high quality debt instruments with relatively short-term maturities. The Company does not use derivative financial instruments in its investment portfolio. Due to the short-term nature of our investment portfolio and the current low interest rate environment, our downside exposure to interest rate risk is minimal.
 
To provide a meaningful assessment of the interest rate risk associated with our investment portfolio, we performed a sensitivity analysis to determine the impact a change in interest rates would have on the value of our investment portfolio. At March 26, 2011, an immediate one percent, or 100 basis points, increase or decrease in interest rates could result in a $1.8 million fluctuation in our annual interest income. However, our
 
Page 33 of 71

Table of Contents

investment portfolio holdings as of March 26, 2011, yielded less than 100 basis points, which reduces our downside interest rate risk to the amount of interest income recognized in fiscal year 2011, or $0.9 million. At March 27, 2010, an immediate one percent, or 100 basis points, increase or decrease in interest rates could result in a $1.3 million fluctuation in our annual interest income. However, our investment portfolio holdings as of March 27, 2010, yielded less than 100 basis points, which reduced our downside interest rate risk to an amount slightly less than the $1.3 million calculation. At March 28, 2009, an immediate one percent, or 100 basis points, increase or decrease in interest rates could have resulted in a $1.5 million fluctuation in our annual interest income. For all of these fiscal years, the risks associated with fluctuating interest rates were limited to our annual interest income and not the underlying principal as we generally have the ability to hold debt related investments to maturity. The amounts disclosed in this paragraph are based on a 100 basis point fluctuation in interest rates applied to the average cash balance for that fiscal year.
 
Foreign Currency Exchange Risk
 
Our revenue and spending is transacted primarily in U.S. dollars; however, in fiscal years 2011, 2010, and 2009, 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, 2011, and March 27, 2010, 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, from time to time, have changes in exchange rates that 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 Stockholders of Cirrus Logic, Inc.
 
We have audited the accompanying consolidated balance sheets of Cirrus Logic, Inc. as of March 26, 2011 and March 27, 2010, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three fiscal years in the period ended March 26, 2011. 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.

Report of Independent Registered Public Accounting Firm
 
The Board of Directors and Stockholders of Cirrus Logic, Inc.
 
We have audited Cirrus Logic, Inc.’s internal control over financial reporting as of March 26, 2011, 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 included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.
 
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
In our opinion, Cirrus Logic, Inc. maintained, in all material respects, effective internal control over financial reporting as of March 26, 2011, 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, 2011 and March 27, 2010, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three fiscal years in the period ended March 26, 2011 of Cirrus Logic, Inc. and our report dated May 25, 2011 expressed an unqualified opinion thereon.

Basis of Presentation
 
We prepare financial statements on a 52- or 53-week year that ends on the last Saturday in March. Fiscal years 2011, 2010, and 2009 were all 52-week years.
 
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.
 
Reclassifications
 
Certain reclassifications have been made to prior year balances in order to conform to the current year’s presentation of financial information.
 
Use of Estimates
 
The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires 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.

2.  	Summary of Significant Accounting Policies	
 
Cash and Cash Equivalents
 
Cash and cash equivalents consist primarily of money market funds, commercial paper, and U.S. Government Treasury and Agency instruments with original maturities of three months or less at the date of purchase.

Restricted Investments
 
As of March 26, 2011, and March 27, 2010, we had restricted investments of $5.8 million and $5.9 million, respectively, in support of our letters 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, and are scheduled for periodic declines in amount to $2.6 million in September 2011 and expiring in May 2012. The $0.1 million decrease in fiscal year 2011 relates to an agreement executed on March 24, 2010, for the purchase of real property for the construction of our U.S. headquarters in Austin, Texas.
 
Marketable Securities
 
We determine the appropriate classification of marketable securities at the time of purchase and reevaluate this designation as of each balance sheet date. We classify these securities as either held-to-maturity, trading, or available-for-sale in accordance with FASB ASC Topic 320, “ Investments — Debt and Equity Securities. ” As of March 26, 2011, and March 27, 2010, all marketable securities and restricted investments were classified as available-for-sale securities. The Company classifies its investments as “available for sale” because it expects to possibly sell some securities prior to maturity. The Company’s investments are subject to market risk, primarily interest rate and credit risk. The Company’s investments are managed by an outside professional manager within investment guidelines set by the Company. Such guidelines include security type, credit quality, and maturity, and are intended to limit market risk by restricting the Company’s investments to high quality debt instruments with relatively short-term maturities. The fair value of investments is determined using observable or quoted market prices for those 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):

 	 	Year Ended	 	
 	 	March 26,	 	 	March 27,	 	
 	 	2011	 	 	2010

Inventories	 	$	40,497	 	 	$	35,396	 	

 
Property, Plant and Equipment, net
 
Property, plant 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 39 years.
 
Page 43 of 71

Table of Contents

Leasehold improvements are depreciated over the shorter of the term of the lease or the estimated useful life. Furniture, fixtures, machinery, and equipment are all depreciated over a useful life of three to 10 years, while buildings are depreciated over a period of up to 39 years. In general, our capitalized software is amortized over a useful life of three years, with capitalized enterprise resource planning software being amortized over a useful life of 10 years. Gains or losses related to retirements or dispositions of fixed assets are recognized in the period incurred.

The increase in the land and buildings balance in fiscal year 2011 was attributable to the purchase of land for our new headquarters in Austin, Texas, which is currently under construction. Depreciation and amortization expense on property, plant, and equipment for fiscal years 2011, 2010, and 2009, was $4.8 million, $4.3 million, and $4.7 million, respectively. During fiscal year 2011 we retired fully depreciated assets with an original cost of $3.7 million.
 
Other-Than-Temporary Impairment
 
All of the Company’s available-for-sale investments, non-marketable securities, and other investments are subject to a periodic impairment review pursuant to FASB ASC Topic 320, “ Investments — Debt and Equity Securities. ” Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. Marketable securities are evaluated for impairment if the decline in fair value below cost basis is significant and/or has lasted for an extended period of time. Non-marketable securities or other investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. For investments accounted for using the cost method of accounting, management evaluates information (e.g., budgets, business plans, financial statements) in addition to quoted market price, if any, in determining whether an other-than-temporary decline in value exists. Factors indicative of an other-than-temporary decline include recurring operating losses, credit defaults, and subsequent rounds of financings at an amount below the cost basis of the investment. When a decline in value is deemed to be other-than-temporary, we recognize an impairment loss in the current period’s operating results to the extent of the decline.
 
Goodwill and Intangibles, net
 
The Company reports goodwill and other intangible assets in accordance with FASB ASC Topic 350, “ Intangibles — Goodwill and Other. ” Intangible assets include purchased technology licenses and patents that are reported at cost and are amortized on a straight-line basis over their useful lives, generally ranging from one to ten years. Acquired intangibles include existing technology, core technology or patents, license agreements, trademarks, covenants not-to-compete and customer agreements. These assets are amortized on a straight-line basis over lives ranging from four to fifteen years. Goodwill is recorded at the time of an acquisition and is calculated as the difference between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. Accounting for acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the fair value of the net tangible and intangible assets acquired, including in-process research and development (“IPR&D”).
 
Page 44 of 71

Table of Contents

Goodwill and intangible assets deemed to have indefinite lives are not amortized but are subject to annual impairment tests. If the assumptions and estimates used to allocate the purchase price are not correct, or if business conditions change, purchase price adjustments or future asset impairment charges could be required. The value of our intangible assets, including goodwill, could be impacted by future adverse changes such as: (i) any future declines in our operating results, (ii) a decline in the valuation of technology company stocks, including the valuation of our common stock, (iii) a significant slowdown in the worldwide economy and the semiconductor industry, or (iv) any failure to meet the performance projections included in our forecasts of future operating results. In accordance with FASB ASC Topic 350, the Company tests goodwill and indefinite lived intangibles for impairment on an annual basis or more frequently if the Company believes indicators of impairment exist. Impairment evaluations involve management estimates of asset useful lives and future cash flows. Significant management judgment is required in the forecasts of future operating results that are used in the evaluations. It is possible, however, that the plans and estimates used may be incorrect. If our actual results, or the plans and estimates used in future impairment analysis, are lower than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges in a future period.
 
Long-Lived Assets
 
In accordance with FASB ASC Topic 360, “ Property, Plant, and Equipment ,” we test for impairment losses on long-lived assets and definite-lived intangibles 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.
 
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 remeasured using the monthly average exchange rates in effect for the period in which the items occur. For all periods presented, our foreign currency remeasurement expense was not significant.
 
Concentration of Credit Risk
 
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. 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.
 
For fiscal years 2011 and 2010, we had one customer, Futaihua Industrial, who represented 42 percent and 20 percent of our consolidated gross accounts receivable. For fiscal years 2011 and 2010, we had one distributor, Avnet, Inc., who represented 17 percent and 17 percent of our consolidated gross accounts receivable. No other distributor or customer had receivable balances that represented more than 10 percent of consolidated gross accounts receivable as of the end of fiscal years 2011 or 2010.

Table of Contents

Since the components we produce are largely proprietary and generally not available from second sources, we consider our end customer to be the entity specifying the use of our component in their design. These end customers may then purchase our products directly from us, from a distributor, or through a third party manufacturer contracted to produce their end product. For fiscal years 2011 and 2010, our ten largest end customers represented approximately 62 percent and 54 percent of our sales. For fiscal years 2011, 2010, and 2009, we had one end customer, Apple Inc., who purchased through multiple contract manufacturers and represented approximately 47 percent, 35 percent, and 16 percent of the Company’s total sales, respectively. Further, we had one distributor that represented 24 percent, 26 percent, and 33 percent of our sales for fiscal years 2011, 2010, and 2009 respectively. No other customer or distributor represented more than 10 percent of net sales in fiscal years 2011, 2010, or 2009.
 
Revenue Recognition
 
We recognize revenue in accordance with ASC Topic 605, “ Revenue Recognition,” when all of the following criteria are met: persuasive evidence that an arrangement exists, delivery of goods has occurred, the sales price is fixed or determinable and collectability is reasonably assured. We evaluate our distributor arrangements, on a distributor by distributor basis, with respect to each of the four criteria above. For a majority of our distributor arrangements, we provide rights of price protection and stock rotation. As a result, revenue is deferred at the time of shipment to our domestic distributors and certain international distributors due to the determination that the ultimate sales price to the distributor is not fixed or determinable. Once the distributor has resold the product, and our final sales price is fixed or determinable, we recognize revenue for the final sales price and record the related costs of sales. For certain of our smaller international distributors, we do not grant price protection rights and provide minimal stock rotation rights. For these distributors, revenue is recognized upon delivery to the distributor, less an allowance for estimated returns, as the revenue recognition criteria have been met upon shipment.
 
Further, the Company defers the associated cost of goods sold on our consolidated balance sheet, net within the deferred income on shipments to distributors’ current liability caption. The Company routinely evaluates the products held by our distributors for impairment to the extent such products may be returned by the distributor within these limited rights and such products would be considered excess or obsolete if included within our own inventory. Products returned by distributors and subsequently scrapped have historically been immaterial to the Company.
 
Warranty Expense
 
We warrant that our products, when delivered, will be free from defects in material workmanship under normal use and service. Our obligations are generally 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. We have recorded an estimated accrual, for all periods presented, for such returns based upon historical trends.
 
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 $1.3 million, $1.0 million, and $1.5 million in fiscal years 2011, 2010, and 2009, respectively.
 
Stock-Based Compensation
 
Stock-based compensation is measured at the grant date based on the grant-date fair value of the awards and is recognized as an expense, on a ratable basis, over the vesting period, which is generally between zero and four years. Determining the amount of stock-based compensation to be recorded requires the Company to develop estimates used in calculating the grant-date fair value of stock options. The Company calculates the
 
Page 46 of 71

Table of Contents

grant-date fair value for stock options using the Black-Scholes valuation model. The use of valuation models requires the Company to make estimates of assumptions such as expected volatility, expected term, risk-free interest rate, expected dividend yield, and forfeiture rates. See Note 13 — “ Stockholders’ Equity ” for additional information relating to stock-based compensation.
 
Income Taxes
 
We report income taxes in accordance with FASB ASC Topic 740, “ 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 against a portion of our net U.S. deferred tax assets due to uncertainties regarding their realization. We evaluate our ability to realize our deferred tax assets on a quarterly basis.
 
We recognize liabilities for uncertain tax positions based on the two-step process. The first step requires us to determine if the weight of available evidence indicates that the tax position has met the threshold for recognition; therefore, we must evaluate whether it is more likely than not that the position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step requires us to measure the tax benefit of the tax position taken, or expected to be taken, in an income tax return as the largest amount that is more than 50 percent likely of being realized upon ultimate settlement. We reevaluate the uncertain tax positions each quarter based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit, and new audit activity. Depending on the jurisdiction, such a change in recognition or measurement may result in the recognition of a tax benefit or an additional charge to the tax provision in the period.
 
Net Income Per Share
 
Basic net income per share is based on the weighted effect of common shares issued and outstanding and is calculated by dividing net income by the basic weighted average shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares used in the basic net income per share calculation, plus the equivalent number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding. These potentially dilutive items consist primarily of outstanding stock options and restricted stock awards.
 
The weighted outstanding options excluded from our diluted calculation for the years ended March 26, 2011, March 27, 2010, and March 28, 2009, were 615,000, 8,043,000, and 7,796,000, respectively, as the exercise price exceeded the average market price during the period.
 
Accumulated Other Comprehensive Loss
 
We report our accumulated other comprehensive loss based upon FASB ASC Topic 220, “ Comprehensive Income . ” Our accumulated other comprehensive loss is comprised of foreign currency translation adjustments from prior years when we had subsidiaries whose functional currency was not the U.S. Dollar, as well as unrealized gains and losses on investments classified as available-for-sale. See Note 14 — “ Accumulated Other Comprehensive loss ” for additional discussion.
 
Recently Issued Accounting Pronouncements
 
In January 2010, the FASB issued Accounting Standards Update (“ASU”) No. 2010-06, “Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements” (“ASU 2010-06”), which amends the disclosure guidance with respect to fair value measurements. Specifically, the new guidance requires disclosure of amounts transferred in and out of Levels 1 and 2 fair value measurements, a reconciliation presented on a gross basis rather than a net basis of activity in Level 3 fair value measurements, greater disaggregation of the assets and liabilities for which fair value measurements are presented and more robust disclosure of the valuation techniques and inputs used to measure Level 2 and 3 fair value measurements. ASU 2010-06 was effective for interim and annual reporting periods beginning after December 15, 2009, with the exception of the new guidance around the Level 3 activity reconciliations, which

is effective for fiscal years beginning after December 15, 2010. The adoption of this pronouncement did not have a material impact on our consolidated financial statements.

3.  	Marketable Securities	
 
The Company’s investments that have original maturities greater than 90 days have been classified as available-for-sale securities in accordance with FASB ASC Topic 320, “ Investments — Debt and Equity Securities. ” Marketable securities are categorized on the consolidated balance sheet as restricted investments and marketable securities, as appropriate.
 
The following table is a summary of available-for-sale securities (in thousands):

 	 	Amortized	 	 	Gross Unrealized	 	 	Gross Unrealized	 	 	Estimated Fair Value	 	
As of March 26, 2011:	 	Cost	 	 	Gains	 	 	Losses	 	 	(Net Carrying Amount)

Total securities	 	$	172,214	 	 	$	63	 	 	$	(47	)	 	$	172,230	 	

 
The Company’s specifically identified gross unrealized losses of $47 thousand relates to 28 different securities with a total amortized cost of approximately $61.8 million at March 26, 2011. Because the Company does not intend to sell the investments at a loss and the Company will not be required to sell the investments before recovery of its amortized cost basis, it did not consider the investment in these securities to be other-than-temporarily impaired at March 26, 2011. Further, the securities with gross unrealized losses had been in a continuous unrealized loss position for less than 12 months as of March 26, 2011.

Total securities	 	$	125,396	 	 	$	189	 	 	$	(68	)	 	$	125,517	 	

 
The Company’s specifically identified gross unrealized losses of $68 thousand relates to 30 different securities with a total amortized cost of approximately $46.2 million at March 27, 2010. Because the Company does not intend to sell the investments at a loss and the Company will not be required to sell the investments before recovery of its amortized cost basis, it did not consider the investment in these securities to be other-than-temporarily impaired at March 27, 2010. Further, the securities with gross unrealized losses had been in a continuous unrealized loss position for less than 12 months as of March 27, 2010.
 
The cost and estimated fair value of available-for-sale investments by contractual maturity were as follows:

5.  	Non-Marketable Securities	
 
In the second quarter of the current fiscal year, the Company recognized a loss on the impairment of an equity investment in the amount of $0.5 million. Our original investment was in the form of a note receivable, which was then converted into an equity security during the second quarter of the current fiscal year. After the conversion, we determined that an impairment indicator existed related to our cost method investment. We performed a fair value analysis of our cost method investment in accordance with FASB ASC Topic 320 — “Investments — Debt and Equity Securities.” Based on the results of this analysis we recognized an impairment of $0.5 million to reduce the carrying value of the cost method investment to zero. The impairment was recorded as a separate line item on the consolidated statement of operations in operating expenses under the caption “Impairment of (proceeds from) non-marketable securities.”
 
In the third quarter of fiscal year 2010, as part of a convertible note financing round for Magnum Semiconductor, Inc. (“Magnum”), a company that we previously had an investment in, we received proceeds of $0.5 million from Magnum as consideration for our ownership interest in Magnum securities, which we determined had been fully impaired in fiscal year 2008. The proceeds were recorded as a separate line item on the consolidated statement of operations in operating expenses under the caption “Impairment of (proceeds from) non-marketable securities.”
 
Our consolidated balance sheet at March 26, 2011, reflects no value attributable to investments in non-marketable securities.

6.  	Acquisitions	
 
On December 8, 2008, we executed an asset purchase agreement with Thaler Corporation of Tucson, Arizona, an entity specializing in the manufacture of precision analog and mixed signal devices. The purchase price of the acquisition was $1.1 million, which consisted primarily of intangible assets and inventory. The

intangible assets, which were $0.8 million of the purchase price, are being amortized over a period of 5 years. Fifty percent of the purchase price, or $550 thousand, was paid in cash at closing, and the remaining balance was paid on April 8, 2009.

In the fourth quarter of fiscal year 2009, we noted several impairment indicators surrounding patents that we acquired in June 2007. We performed an impairment analysis under FASB ASC Topic 360 and noted that the undiscounted cash flows estimated to be generated from these patents were less than the carrying amount of the assets. We then compared the estimated fair value of these assets to their carrying amount and recognized an impairment loss of $2.1 million. The impairment was recorded as a separate line item on the statement of operations in operating expenses under the caption “Impairment of intangible assets.”
 
Amortization expense for all intangibles in fiscal years 2011, 2010, and 2009 was $3.3 million, $3.6 million, and $3.5 million, respectively. The following table details the estimated aggregate amortization expense for all intangibles owned as of March 26, 2011 for each of the five succeeding fiscal years (in thousands):

8.  	Commitments and Contingencies	
 
Facilities and Equipment Under Operating Lease Agreements
 
With the exception of the Apex facility in Tucson, Arizona, 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. As of May 1, 2011, our principal leased facilities, located in Austin, Texas, consisted of approximately 214,000 square feet of office space. This leased space includes our headquarters and engineering facility, which has 197,000 square feet with lease terms that extend into the summer of calendar year 2012, and 17,000 square feet of leased space at our failure analysis facility with lease terms that extend into calendar year 2013. We have subleased approximately 37,000 square feet of space at our Austin headquarters with sublease terms that extend into the summer of calendar year 2012. The Company has commenced construction of our planned new headquarters facility in Austin, Texas with completion expected in the summer of calendar year 2012. Upon completion, we anticipate relocating our

headquarters employees into the newly constructed facility with the current lease agreement being allowed to terminate under the terms of the agreement.
 
The aggregate minimum future rental commitments under all operating leases, net of sublease income, for the following fiscal years are (in thousands):

Total rent expense was approximately $4.6 million, $4.4 million, and $5.9 million, for fiscal years 2011, 2010, and 2009, respectively. Sublease rental income was $1.1 million, $1.2 million, and $2.1 million, for fiscal years 2011, 2010, and 2009, respectively. During fiscal years 2011, 2010, and 2009, we recorded approximately $0.1 million, $0.4 million, and $0.1 million in rent expense reductions, respectively, to adjust our loss contingency accrual for a change in sublease assumptions with regards to our facilities in Austin, Texas and Fremont, California.
 
As of March 26, 2011, a total of $1.0 million related to vacated leases remained accrued, of which $0.3 million has been classified as long-term. These amounts are included in the table above. The $0.4 million in facilities restructuring accruals that existed for these leases as of March 26, 2011 are discussed in greater detail in Note 11 — Restructuring Costs and Other.
 
Wafer, Assembly and Test Purchase Commitments
 
We rely primarily on third-party foundries for our wafer manufacturing needs. As of March 26, 2011, we had agreements with multiple foundries for the manufacture of wafers. None of these foundry agreements have 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, 2011, we had foundry commitments of $19.2 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 $2.6 million at March 26, 2011.
 
We have transitioned the majority 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, 2011 was $3.4 million.
 
Other open purchase orders as of March 26, 2011 amount to $1.9 million and primarily relate to raw material costs incurred in our facility in Tucson, Arizona, which continues to serve as the assembly and test facility for our Apex products.

9.  	Legal Matters	
 
During the fourth quarter of the current fiscal year, in response to certain patent infringement allegations, the Company incurred $57 thousand as part of the execution of a Settlement and License Agreement. During the third quarter of fiscal year 2011, the Company received proceeds of $113 thousand reflecting the final resolution of litigation with Silvaco Data Systems. Of this amount, $30 thousand represented the settlement
 
Page 51 of 71

awarded to the Company, and the balance represented recoveries of certain litigation expenses and interest. Finally, during the first quarter of fiscal year 2011, the Company incurred $135 thousand in settlement costs related to a dispute with a former distributor of the Company’s products. These transactions, in the cumulative net amount of $162 thousand, are reflected as a separate line item on the consolidated statement of operations in operating expenses under the caption “Provision (benefit) for litigation expenses and settlements.”
 
On March 23, 2009, a lawsuit was filed against the Company alleging patent infringement. During the third quarter of fiscal year 2010, a settlement agreement was concluded which resulted in Cirrus Logic recognizing a $135 thousand charge related to the suit. In a separate matter, on June 17, 2009, during the first quarter of fiscal year 2010, the Company received proceeds of a net $2.7 million from its insurance carrier as part of the final settlement of litigation where a purported stockholder filed a derivative lawsuit in the state district court in Travis county, Texas against current and former officers and directors of the Company related to certain prior grants of stock options by the Company. The proceeds of $2.7 million were recorded as a recovery of costs previously incurred in accordance with FASB ASC Topic 450, “ Contingencies. ” The combined net amount of $2.6 million from these two fiscal year 2010 transactions are reflected as a separate line item on the consolidated statement of operations in operating expenses under the caption “Provision (benefit) for litigation expenses and settlements.”
 
During fiscal year 2009, we recognized a $2.2 million charge related to legal fees and expenses associated with the derivative lawsuits. The charge was recorded as a separate line item on the consolidated statement of operations in operating expenses under the caption “ Provision (benefit) for litigation expenses and settlements. ”
 
As of the balance sheet date, to the best of our knowledge, the Company is not a party to any material pending litigation. From time to time, 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 our industry. As to any of these potential claims or litigation, we cannot predict the ultimate outcome with certainty.

10.  	Fair Value Measurements	
 
The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

 	§   	Level 1 — Quoted prices in active markets for identical assets or liabilities.	
 		
 	§   	Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.	
 		
 	§   	Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.	
 
As of March 26, 2011, the Company’s cash equivalents and restricted investments of $42.8 million, and short and long-term investments of $172.2 million, are all valued using quoted prices generated by market transactions involving identical assets, or Level 1 assets as defined under FASB ASC Topic 820.

Financial assets with carrying amounts approximating fair value include cash and cash equivalents, restricted investments, and marketable securities. The carrying amount of these financial assets approximates fair value because of their short maturity. The fair values of long-term marketable securities are valued using quoted prices generated by market transactions involving identical assets.

11.  	Restructuring Costs and Other	
 
During fiscal year 2011, we recorded net restructuring charges of six thousand dollars as a separate line item on the statement of operations in operating expenses under the caption “Restructuring costs and other, net.”
 
During fiscal year 2010, we recorded net restructuring charges of $0.5 million as a separate line item on the statement of operations in operating expenses under the caption “Restructuring costs and other, net.” The restructuring charge primarily relates to a change in sublease assumptions for the Company’s corporate offices in Austin, Texas.

Fiscal year 2011 activity reflected a net reduction in the 2004 restructuring accrual of $0.9 million, which included an increase in the provision for normal accretion of $0.1 million for the period. Fiscal year 2010 activity reflected a net reduction in the 2004 restructuring accrual of $0.6 million, which included an increase in the provision for a $0.5 million restructuring charge brought about by a change in sublease assumptions, as well as normal accretion of $0.1 million for the period. Fiscal year 2009 activity reflected a net reduction in the 2004 restructuring accrual of $0.3 million, which included an increase in the provision for normal accretion for the period.
 
As of March 26, 2011, we have a remaining restructuring accrual of $0.4 million, primarily related to net lease expenses that will be paid over the respective lease terms through the summer of calendar year 2012, along with other anticipated lease termination costs. We have classified the short-term portion of our restructuring activities, $0.3 million, as “Other accrued liabilities.”

12.  	Employee Benefit Plans	
 
We have a 401(k) Profit Sharing Plan (the “Plan”) covering all of our qualifying domestic employees. Under the Plan, employees may elect to contribute any percentage of their annual compensation up to the annual IRS limitations. We match 50 percent of the first 6 percent of the employees’ annual contribution to
 
Page 54 of 71

the plan. We made matching employee contributions of $1.0 million, $0.9 million, and $0.9 million during fiscal years 2011, 2010, and 2009, respectively.

13.  	Stockholders’ Equity	
 
Share Repurchase Program
 
In the third quarter of the current fiscal year, the Company completed the repurchase of approximately 1.8 million shares of the Company’s common stock, at a total cost of $22.8 million, or $12.94 per share. Of this amount, 1.5 million shares of the Company’s common stock were repurchased pursuant to the remaining portion of the $20 million share repurchase program authorized by the Board of Directors in January 2009. In addition, as of March 26, 2011, 216 thousand shares have been repurchased, none of which occurred in the fourth quarter of the Company’s current fiscal year, at a cost of $2.8 million under a new $80 million share repurchase program approved by our Board of Directors and which the Company publicly announced on November 4, 2010. All shares of our common stock that were repurchased under these share repurchase programs were cancelled upon consummation of the daily repurchase transactions.
 
On January 30, 2008, we announced that our Board authorized a share repurchase program of up to $150 million. The Company repurchased 13.3 million shares of its common stock for $71.1 million during fiscal year 2008 and completed the program in fiscal year 2009 by repurchasing a total of 11.2 million shares of our common stock for $78.9 million. A cumulative 24.5 million shares were acquired at a total cost of $150 million. All of these shares were repurchased in the open market and were funded from existing cash. All shares of our common stock that were repurchased were cancelled upon consummation of the daily repurchase transactions.
 
Preferred Stock
 
We have 1.5 million shares of Series A Participating Preferred Stock. As of March 26, 2011 we have not issued any of the authorized shares.
 
Stock Compensation Expense
 
The Company is currently granting equity awards from the 2006 Stock Incentive Plan (the “Plan”), which was approved by stockholders in July 2006. The Plan provides for granting of stock options, restricted stock awards, restricted stock units, performance awards, phantom stock awards, and bonus stock awards, or any combination of the foregoing. To date, the Company has granted stock options, restricted stock awards, and restricted stock units under the Plan. Stock options generally vest between zero and four years, and are exercisable for a period of ten years from the date of grant. Generally, restricted stock awards and restricted stock units are subject to cliff vesting schedules of four and three years, respectively.

Share based compensation effects on financing activities cash flow	 	 	—	 	 	 	—	 	 	 	—	 	

The total share based compensation expense included in the table above and which is attributable to restricted stock awards and restricted stock units was $1.1 million, $0.1 million, and $0.2 million for fiscal years 2011, 2010, and 2009, respectively.
 
As of March 26, 2011, there was $17.1 million of compensation costs related to non-vested stock options, restricted stock awards, and restricted stock units granted under the Company’s equity incentive plans not yet recognized in the Company’s financial statements. The unrecognized compensation cost is expected to be recognized over a weighted average period of 1.17 years for stock options, 1.27 years for restricted stock awards, and 2.54 years for restricted stock units.
 
Stock Option Awards
 
We estimated the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing model using a dividend yield of zero and the following additional assumptions:

 	 	Year Ended	
 	 	March 26,	 	March 27,	 	March 28,	
 	 	2011	 	2010	 	2009	
 		
Expected stock price volatility	 	 	52.03-67.11	%	 	 	50.71-56.59	%	 	 	47.23-59.22	%	
Risk-free interest rate	 	 	1.19-2.06	%	 	 	1.80-2.25	%	 	 	1.48-2.99	%	
Expected term (in years)	 	 	3.83-4.34	 	 	 	4.33-4.64	 	 	 	4.08-4.23	 	

The Black-Scholes valuation calculation requires us to estimate key assumptions such as stock price volatility, expected term, risk-free interest rate and dividend yield. The expected stock price volatility is based upon implied volatility from traded options on our stock in the marketplace. The expected term of options granted is derived from an analysis of historical exercises and remaining contractual life of stock options, and represents the period of time that options granted are expected to be outstanding. The risk-free interest rate reflects the yield on zero-coupon U.S. Treasury securities for a period that is commensurate with the expected term assumption. Finally, we have never paid cash dividends, do not currently intend to pay cash dividends, and thus have assumed a zero percent dividend yield.
 
Using the Black-Scholes option valuation model, the weighted average estimated fair values of employee stock options granted in fiscal years 2011, 2010, and 2009, were $9.61, $2.89, and $2.82, respectively.

During fiscal year 2011, we received a net $31.0 million from the exercise of 4.7 million stock options granted under the Company’s Stock Plans.
 
The total intrinsic value of stock options exercised during fiscal year 2011, 2010, and 2009 was $50.4 million, $0.8 million, and $0.9 million, respectively. Intrinsic value represents the difference between the market value of the Company’s common stock at the time of exercise and the strike price of the stock option.
 
As of March 26, 2011, approximately 14.4 million shares of common stock were reserved for issuance under the Stock Option Plans.

Restricted Stock Awards
 
The Company periodically grants restricted stock awards (“RSA’s”) to select employees. The grant date for these awards is equal to the measurement date and the awards are valued as of the measurement date and amortized over the requisite vesting period. Generally, the current unreleased RSA awards vest 100 percent on the fourth anniversary of the grant date. A summary of the activity for RSA’s in fiscal year 2011, 2010 and 2009 is presented below (in thousands, except per share amounts):

The weighted average remaining recognition period for RSA’s outstanding as of March 26, 2011 was 1.27 years. RSA’s with a fair value of $37 thousand, $65 thousand, and $62 thousand became vested during fiscal years 2011, 2010, and 2009, respectively.
 
Restricted Stock Units
 
Commencing in fiscal year 2011, the Company began granting restricted stock units (“RSU’s”) to select employees. These awards are valued as of the grant date and amortized over the requisite vesting period. Generally, RSU’s vest 100 percent on the third anniversary of the grant date. Each full value award, including RSU’s and RSA’s, reduce the total shares available for grant under the 2006 option plan at a rate of 1.5 shares per RSA or RSU granted. As of March 26, 2011, approximately 1.0 million shares attributable to RSU awards were reserved for issuance under the Option Plans, which includes the additional shares associated with this full value award multiplier. A summary of the activity for RSU’s in fiscal year 2011 is presented below (in thousands, except per share amounts):

RSU’s outstanding that are expected to vest are presented net of estimated future forfeitures, which are estimated as compensation costs are recognized. No RSU’s became vested during fiscal year 2011.

14.  	Accumulated Other Comprehensive Loss	
 
Our accumulated other comprehensive 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.

These net deferred tax assets have been categorized on the Consolidated Balance Sheets as follows:

 	 	March 26,	 	 	March 27,	 	
 	 	2011	 	 	2010	 	
 		
Current deferred tax assets	 	$	30,797	 	 	$	12,549

The current and long-term deferred tax assets are disclosed separately under their respective captions on the consolidated balance sheets, while the long term deferred tax liabilities are aggregated under the caption “Other long- term liabilities” on the consolidated balance sheets.
 
The valuation allowance decreased by $157.8 million in fiscal year 2011 and decreased by $26.3 million in fiscal year 2010. During fiscal year 2011, the Company evaluated the ability to realize its deferred tax assets by using a three year forecast to determine the amount of net operating losses and other deferred tax assets that would be utilized if we achieved the results set forth in our three year forecast. The Company limited the forecast period to three years because of the cyclical and competitive nature of the semiconductor industry, and the Company’s reliance on a key customer who accounted for approximately 47 percent of total sales in fiscal year 2011. There can be no assurance that we will achieve the results set forth in our three year forecast and our actual results may differ materially from our forecast.
 
At the end of fiscal year 2011, after the release of a significant portion of the valuation allowance, the Company has a remaining valuation allowance of $68.4 million of its deferred tax assets. Of that amount, there is approximately $30.5 million of deferred tax assets that may never be recognized because they pertain to federal or state tax credits that may expire before being utilized.
 
At March 26, 2011, we had federal net operating loss carryforwards of $423.7 million. Of that amount, $27.9 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. Because the Company has elected the “with and
 
Page 61 of 71

Table of Contents

without” method for purposes of tracking its excess stock deductions, the amount of Federal net operating loss included in deferred tax assets is $350.6 million which yields a tax effected deferred tax asset of $122.7 million. The Company has $73.1 million of excess stock deductions which are not included in deferred tax assets. The tax benefit from these deductions will increase additional paid-in capital when they are deemed realized under the “with and without” method. We have net operating losses in various states that total $104.9 million. The federal net operating loss carryforwards expire in fiscal years 2019 through 2029. The state net operating loss carryforwards expire in fiscal years 2012 through 2029. We also have non-U.S. net operating losses of $1.9 million which do not expire.
 
There are federal research and development credit carryforwards of $22.8 million that expire in fiscal years 2012 through 2031. There are $14.7 million of state research and development credits. Of that amount, $3.0 million will expire in fiscal years 2022 through 2027. The remaining $11.7 million of state research and development credits are not subject to expiration.
 
We have approximately $339 thousand 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 $121 thousand. With our current tax attributes, if the earnings were distributed, we would most likely not accrue any additional current income tax expense because this income would be offset by our net operating loss carryforwards and other future deductions.
 
We record unrecognized tax benefits for the estimated risk associated with tax positions taken on tax returns. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows (in thousands):

Balance at March 27, 2010	 	$	  85	 	
Additions based on tax positions related to the current year	 	 	—	 	
Reductions for tax positions of prior years	 	 	—

Reductions related to expirations of statutes of limitation	 	 	(85	)	
 	 	 	 	 	
Balance at March 26, 2011	 	$	0	 	

 
The Company does not believe that its unrecognized tax benefits will significantly increase or decrease during the next 12 months.
 
We accrue interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes. We did not record any interest or penalties during fiscal year 2011.
 
The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax in multiple state and foreign jurisdictions. Fiscal years 2008 through 2011 remain open to examination by the major taxing jurisdictions to which we are subject.

17.  	Segment Information	
 
We determine our operating segments in accordance with FASB ASC Topic 280, “Segment Reporting.” Our Chief Executive Officer (“CEO”) has been identified as the chief operating decision maker as defined by FASB ASC Topic 280.
 
The Company operates and tracks its results in one reportable segment based on the aggregation of activity from its two product lines under ASC Topic 280. 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, supply chain management, various research and development and engineering support, in addition to the general and administrative functions of human resources, legal, finance and information technology. Therefore, there is no complete, discrete financial information maintained for these product lines. Revenue from our product lines are as follows (in thousands):

ITEM 9.  	Changes in and Disagreements with Accountants on Accounting and Financial Disclosure	
 
None.

Item 9A.  	Controls and Procedures	
 
Disclosure Controls and Procedures
 
The Company’s management carried out an evaluation, under the supervision and with the participation of the CEO and CFO, of the effectiveness of the design and operation of Company’s disclosure controls and procedures (as defined in Securities Exchange Act of 1934 Rules 13a-15(c) and 15d-15(e)) as of March 26, 2011. Based on that evaluation, the Company’s CEO and CFO have concluded that such disclosure controls and procedures were effective in alerting them in a timely manner to material information relating to the Company required to be included in its periodic reports filed with the SEC.
 
Management’s Annual Report on Internal Control Over Financial Reporting
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined under Rule 13a-15(f). Under the supervision and with the participation of our management, including our CEO and CFO, 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 limitation, 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 its assessment of internal control over financial reporting, management has concluded that our internal control over financial reporting was effective as of March 26, 2011, 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 management’s assessment of our internal control over financial reporting as of March 26, 2011, included in Item 8 of this report.
 
Changes in Internal Control Over Financial Reporting
 
There has been no change in the Company’s internal control over financial reporting during the quarter ended March 26, 2011, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
