PART I

ITEM 1. BUSINESS.

Founded in 1983, Altera Corporation is a global semiconductor company, serving over 13,000 customers within the Telecom and Wireless, Industrial Automation, Military and Automotive, Networking, Computer and Storage, and Other market segments. The Other market segment includes sub-segments of broadcast, consumer, medical and test. Our headquarters facility is located at 101 Innovation Drive, San Jose, California 95134, and our website is www.altera.com. Our common stock trades on the NASDAQ Global Select Market under the symbol ALTR.

Altera designs, manufactures, and markets a variety of products:


•	Programmable logic devices (“PLDs”), which consist of field-programmable gate arrays (“FPGAs”) and complex programmable logic devices (“CPLDs”), are standard semiconductor integrated circuits, or chips, that our customers program to perform desired logic functions in their electronic systems.

•

HardCopy^® application-specific integrated circuits (“ASICs”) transition customer designs from high-density FPGAs to low-cost non-programmable implementations for volume production. Because they are customized only on the last few mask layers, HardCopy ASICs deliver performance that can be an alternative to traditional ASICs, but with reduced development costs and shorter production lead times.


•	Pre-defined design building blocks, known as intellectual property (“IP”) cores, can be licensed by customers to add standard functions to their PLD designs.


•	Proprietary development software, which operates on personal computers and engineering workstations, is used by customers to develop, compile, and verify their designs, and then program their designs into our PLDs.

We were one of the first suppliers of complementary metal oxide semiconductor (“CMOS”) PLDs and are currently a global leader in this market. Our broad range of PLDs offers unique features as well as differing densities and performance specifications, and serve a wide range of customers. An overview of typical PLD applications within these markets is shown in the table below.

Digital Logic Overview

Most electronic systems use three types of digital integrated circuits:


•	Processors, which include microprocessors, microcontrollers, and digital signal processors, control central computing tasks and signal processing.


•	Memory stores programming instructions and data.


•	Logic manages the interchange and manipulation of digital signals within a system.

System designers typically use standard architectures to meet their processor and memory needs, but need a wide variety of logic circuits to differentiate their end products. Most applications use one or more of the following types of logic in their designs:


•	ASICs - Often referred to as standard cells, ASICs are manufactured with custom designs created by the customer. As a result, each ASIC has a fixed function used by a single customer in a single application.


•	Application-specific standard products (“ASSPs”) - ASSPs are standard devices that usually cannot be

customized by the end user. In contrast to an ASIC, which is built for a single customer, an ASSP is built for a specific type of application targeted to a small number of customers. ASSPs are sometimes described as ASICs developed for multiple customers.


•	PLDs - Unlike ASICs and ASSPs, PLDs are standard products that can be customized for a wide range of applications. As a result, PLDs are typically sold to hundreds or thousands of customers. This flexibility offers many advantages, including simple design changes, shorter design cycles, and lower development costs.

In a broad sense, these products compete with each other as they may be used in the same types of applications in electronic systems. However, differences in cost, performance, density, flexibility, ease-of-use, and time-to-market dictate how much they directly compete for particular applications. The table below summarizes key characteristics of ASICs, ASSPs, and PLDs.


	ASIC	ASSP	PLD
CUSTOMIZABLE	Yes, by chip fabrication facility	No	Yes, by end user
ERASABILITY/REPROGRAMMABILITY	No	No	Yes
RELATIVE TIME TO MARKET	Slow	Immediate	Fast
RELATIVE UNIT COST	Low	Moderate	Moderate to high
CUSTOMER'S DEVELOPMENT COST	High	Low	Moderate
FIELD UPGRADABILITY	No	No	Yes

PLDs vs. ASICs and ASSPs

In contrast to ASICs, PLD designs are programmed directly into the PLD. This means that the PLD is fully functional and verified when the design is completed, avoiding the lengthy and complex cycles required to verify and fabricate ASICs. This user programmability allows PLD customers to test and revise their designs quickly and with minimal development cost. In addition to these ease-of-use and time-to-market advantages, PLDs can be upgraded in the field, which allows customers to modify the PLD design after the electronic system has been shipped.

Customers use ASSPs when they need specific fixed functions with little differentiation, for example when implementing certain electronic industry standards. However, ASSPs have fixed functionality, which limits the range of applications they can address. In contrast to ASSPs, PLD flexibility allows customers to define functionality to suit their needs, rather than restrict their system architecture based on ASSP manufacturer specifications. Furthermore, PLD designers can add IP design blocks to execute standardized functions otherwise performed by ASSPs.

These design flexibility advantages historically resulted in a relatively high unit cost for PLDs. Programmability required a larger die size, which typically translated into a higher per-unit cost when compared to ASICs or ASSPs manufactured using the same process technology. As a result, unit volume for PLDs was typically lower than for ASICs or ASSPs. In addition to driving higher cost, the larger die area caused by programmable circuitry may also have disadvantages in terms of performance and power consumption for PLDs when compared to ASICs or ASSPs manufactured using the same process technology.

While PLDs carry the burden of extra die area needed for programmablility, the die size difference versus ASICs and ASSPs has decreased in recent years due to the fact that PLDs are being manufactured on more advanced process technology. For our most current designs, PLD process technology is typically two or three process generations more advanced than ASIC and ASSP process technology. As chip manufacturing becomes more advanced, the total cost of chip development increases, reducing the cost advantage of ASICs and ASSPs. As a result, some ASIC and ASSP suppliers choose to use non-leading-edge process technology for new designs to reduce costs. We believe this has brought us to a “tipping point” with respect to our opportunity to displace ASICs and ASSPs. It is no longer technologically feasible for ASIC and ASSP suppliers to continue to use old process generations for technically advanced systems, and at the same time it is not economically feasible for them to use new generations of technology for low and mid-range volume applications. The “process technology gap” between PLDs and ASIC and ASSP alternatives will increase over time and, when combined with the traditional PLD advantages of greater flexibility, lower development cost, and faster time-to-market, should drive the accelerated adoption of PLDs in the years ahead.

In addition, we believe that innovations in PLD architecture and PLD development tools have also contributed to the increasing use of PLDs over ASICs and ASSPs. Newer PLD capabilities, such as high speed transceivers, Programmable Power Technology, and embedded digital signal processing (“DSP”), help electronics engineers use PLDs to meet increasingly

complex system requirements for performance, power consumption and cost. Consequently, we believe that customers will increasingly use PLDs not only for prototyping, but also for production quantities rather than ASICs or ASSPs.

Strategy and Competition

PLD vendors have innovated and used the most advanced process technology to rapidly reduce PLD cost structure and power consumption while increasing device speed and density. This makes programmable logic an increasingly competitive alternative to ASICs and ASSPs and will likely increase the use of PLDs. In addition, the ability to quickly and efficiently integrate system-level IP within a PLD not only provides advantages relative to ASICs and ASSPs, but it also allows the displacement of other semiconductor products including embedded processors, digital signal processors and microcontrollers.

Our strategy in recent years has not only been to add more prototyping customers, but more importantly, to use cost-optimized products to increase our penetration into higher-volume applications and end markets. Our greatest growth opportunity is in the displacement of ASICs and ASSPs in the development of next generation electronic systems. We believe that the increasing cost of advanced chip manufacturing technology drives the development and use of standard programmable digital integrated circuits. As with microprocessors and memory, PLDs provide the flexibility for the customer to define and change functions without incurring the cost, risk, and delays of custom chip fabrication. Furthermore, we see additional growth opportunity in the efficient integration of PLDs and adjacent semiconductors, including embedded processors.

To capture a larger share of the chips purchased by our customers, we focus on providing the most advanced programmable solutions:


•	PLDs with the speed, density, low power consumption, functionality, and package types to meet customer needs


•	PLDs optimized for low-cost and high-volume applications


•	HardCopy ASICs to enable our customers to move easily from our largest PLDs to a low-cost ASIC


•	Optimized, pre-verified system-level IP cores to speed the design process


•	State-of-the-art development tools that offer low cost, ease of use, and compatibility with other industry-standard electronic design automation (“EDA”) tools


•	A complete customer support system

Not only do we compete with other PLD vendors such as Lattice Semiconductor Corporation, Microsemi Corporation, and Xilinx Inc., but we may also encounter a variety of other semiconductor vendors during a given customer engagement. Semiconductor companies with whom we may compete include Analog Devices Inc., Applied Micro Circuits Corporation, Broadcom Corporation, Freescale Semiconductor Inc., Intel Corporation, LSI Corporation, Marvell Technology Group, Ltd.,

Microchip Technology Inc., NEC Corporation, Nvidia Corporation, PMC-Sierra Inc., ST Microelectronics, Texas Instruments Inc., Toshiba Semiconductor Company, and Vitesse Semiconductor Corporation.

Within the PLD market, there are two distinct sub-segments, CPLDs and FPGAs, which comprise the majority of revenues but, due to product differences, usually do not compete directly for the same customer designs. The FPGA market has outgrown the CPLD market over the last several years. FPGAs now account for approximately 84% of total PLD sales and are expected to continue to be the fastest growing segment of the PLD market. Based on our estimates, we believe that our share of the FPGA market increased from 32% in 2005 to 39% in 2010, and that maintaining or increasing our FPGA market share is important to our long-term growth.

Competition is most intense in the “design-win” phase of the customer's design, when customers select products for use in their systems. Because each vendor's products are proprietary, "drop-in replacement" devices are not available and the cost to switch to a different vendor's product after a system has been designed and prototyped is very high. Therefore, customers rarely switch vendors after the initial selection for a particular design. From the time a design win is secured, it can be two or more years before the customer starts volume purchases of selected devices. When the customer selects a PLD vendor, the selection may take place relatively early in the design process, but it may take several years to complete system design, build prototypes, sample the marketplace for customer acceptance, make modifications, and manufacture in volume. Thus, there is a delay between developing a competitive advantage and experiencing a shift in PLD market share, meaning that market share is a lagging indicator of relative competitive strength. Because it is extremely difficult to forecast the success or timing of a customer's product, and because the end markets are highly fragmented (we have over 13,000 PLD customers), it is difficult even for PLD vendors to gauge their competitive strength in winning designs at a particular point in time.

The principal competitive factors in the PLD market include:


•	Technical innovation


•	Device performance, power consumption, and features


•	Capability and productivity of software development tools and IP cores


•	Pricing and availability


•	Quality and reliability


•	Technical service and customer support


•	Manufacturing and operational competence


•	Customer familiarity with existing vendors and entrenched products

We believe that we compete favorably with respect to these factors and that our proprietary device architecture and installed base of software development systems provides some competitive advantage. Due to unique architectural innovation and advanced technologies, our new product families provide greater functionality and lower power consumption at a lower price for any given density compared to their predecessors. Newer product features such as multi-gigabit transceivers and Programmable Power Technology have enhanced our design-win rate relative to other PLD vendors.

We also believe that our new product families offer capabilities that allow us to compete more favorably against ASICs and ASSPs, as well as against other types of chips such as microcontrollers, microprocessors, and digital signal processors. Designers can add some of the functionality of these other chips to PLDs using pre-built and pre-verified IP cores. An IP core is typically offered in either a “hard” or “soft” form. A hard IP core is embedded into the actual circuitry of our chips. A soft IP core is a licensed design file that our customers incorporate into their design and program onto the PLD. By incorporating more functionality and logic capacity on a programmable chip while providing the necessary design tools and IP cores to design a reliable system, we believe we can enhance the advantages of PLDs over competing solutions.

As is true of the semiconductor industry as a whole, the digital logic segment and the PLD sub-segment are intensely competitive, and each successive product generation is characterized by rapid technological change and price decline. All of these factors may adversely affect our future operating results.

(1) Including HardCopy ASICs, configuration devices, IP cores, and development tools

Each device family has unique functional benefits and different density and performance specifications. Some of our latest device families, typically designed into new equipment, are summarized and described below.

Stratix Series High-End, System-Level FPGAs

Our Stratix^® product families are built using advanced CMOS process technology and address a broad range of applications requiring system integration across all our markets. Programmable Power Technology in Stratix FPGAs help provide high performance and low total power consumption. Embedded HardCopy Blocks within our Stratix V FPGA architecture enable

Altera to quickly create application-targeted devices by efficient hardening of standard or logic-intensive functions, providing further improvements in speed and lower power consumption while offering flexible embedded system functionality. Additionally, our Stratix V GX and Stratix V GT FPGAs offer advanced transceiver capabilities for applications that require reliable, multi-gigabit serial data transfer rates of up to 28 Gbps. Our Stratix V GS FPGAs are optimized for applications requiring high performance, variable precision DSP. Initial shipments of our Stratix V FPGAs are planned in early 2011.

Arria Series Mid-Range, Transceiver-Equipped FPGAs

Our Arria^® product families are built using advanced CMOS process technology and enable a simplified transceiver-based design for applications requiring high-performance data transfer protocols. Arria V GX FPGAs offer best-in-class signal integrity with data transfer rates of up to 10 Gbps, providing designers a high-quality and reliable solution for next-generation high-bandwidth systems across all our markets. Initial shipments of our Arria V GX FPGAs are planned in 2011.

Cyclone Series Low-Cost FPGAs

Our Cyclone^® product families are built using advanced CMOS process technology and bring programmable flexibility to cost-sensitive applications in all our markets. Our Cyclone IV and Cyclone V FPGAs use low-power process technology to meet market requirements for low power consumption. Additionally, our Cyclone V GX FPGAs incorporate up to 12 integrated transceivers with data rates up to 5 Gbps. Architectural innovation allows Cyclone FPGAs to combine a low-cost structure with abundant device resources, making them ideal for high-volume applications. Initial shipments of our Cyclone V GX FPGAs are planned in 2011.

MAX Series CPLDs

Our MAX^® families are instant-on, non-volatile CPLDs that are used in general purpose and portable designs for a broad range of electronics equipment. Our MAX V CPLDs have a revolutionary architecture that significantly reduces total power consumption when compared to competing CPLDs. For the most demanding low-power and battery-operated portable applications, our MAX V CPLDs offer microamp standby current in ultra-small-chip packaging.

HardCopy ASICs

Our HardCopy ASICs offer customers a migration path from high density FPGA families to a low-cost ASIC for high-volume production. For a given process technology, HardCopy ASICs deliver nearly the performance of comparable cell-based ASICs, but with reduced development costs and shorter production lead-times.

In contrast to traditional cell-based ASICs, in which every mask layer is custom and unique to the customer's design, our HardCopy ASICs share a common set of base layers so only the last few mask layers are customized to implement the customer's design. By removing the configuration circuitry, programmable routing, and programmability for logic and memory, we reduce the die size and therefore device cost, but deliver functionality, performance and power characteristics that are equivalent to or more favorable than that of an FPGA.

As a result, customers get the flexibility and time-to-market advantages of a high-density FPGA during the prototyping and early production phases, and then convert the design to a HardCopy ASIC for high volume. This allows HardCopy ASICs to be used in high-volume cost-sensitive applications historically served by traditional cell-based ASICs.

INTELLECTUAL PROPERTY CORES

IP cores are pre-verified building blocks that execute system-level functions. By incorporating more functionality and logic capacity on a programmable chip while providing the necessary design tools and IP cores to design a reliable system, we believe we can enhance the advantages of PLDs over competing solutions.

An IP core is typically offered in either a “hard” or “soft” form. A hard IP core is embedded into the actual circuitry of our chips, which yields a small die area and typically provides advantages in cost, performance, and power consumption. Our recent FPGA product generations have introduced hard IP cores such as variable-precision DSP blocks, multi-gigabit trasnceivers, and a variety of interface protocols.

A soft IP core is a licensed design file that our customers incorporate into their design and program onto the PLD. Customers integrate IP cores in their PLD designs with our proprietary development software. Soft IP cores available for use in our devices include our Nios^® series of embedded processors, our portfolio of MegaCore^® functions that we license to our

customers, and our Altera Megafunction Partners Program ("AMPPSM^") cores, which are pre-verified by us and licensed to our customers by third parties.

The Nios series of embedded processors use a reduced instruction-set computing (“RISC”) architecture and can be efficiently used in our FPGAs and HardCopy ASIC devices as a cost-competitive and flexible alternative to discrete microcontroller solutions. The Nios series of embedded processors compete favorably with many discrete microcontrollers. Other embedded processor IP cores, both hard and soft implementations, are also offered and supported by Altera through partnership agreements with companies including ARM Ltd. and MIPS Technologies.

With IP cores, system designers can focus more time and energy on improving and differentiating the unique aspects of their system designs, rather than spending time designing common off-the-shelf functions. IP cores are essential to providing solutions with higher levels of integration and faster time to market. Today, we offer a broad range of soft IP cores for DSP algorithms, bus interfaces, memory controllers, telecommunications, data communications, microprocessors, and peripherals. Before licensing a soft IP core, customers can download an encrypted soft IP core from our website and verify that it works in their own system designs. While licensing soft IP cores represents a small portion of our net sales, we believe a broad product offering in this area is necessary to compete with ASIC and ASSP vendors as well as other PLD vendors.

DEVELOPMENT TOOLS

To enhance engineering productivity, customers use our proprietary development tools, consisting primarily of the Quartus^® II software, for design entry, design compilation, design verification, and device programming.

Designers can use our development tools on a variety of computing platforms, including Microsoft Windows, UNIX (including Solaris and HP-UX), and Linux operating environments, with built-in interfaces to many industry-standard EDA tools offered by Cadence Design Systems, Inc., Mentor Graphics Corporation, Synopsys, Inc., and others.

Like IP cores, our development tools generate less than 10% of our net sales, but are a critical and necessary element of our product portfolio because they are used to program our devices and can drive our success in competing for design wins against PLD, ASIC, and ASSP vendors.

Research and Development

Our research and development activities focus primarily on PLDs, HardCopy ASICs, IP cores, development software, and hardware. We develop these related products in parallel to provide comprehensive design support to customers. As a result of our research and development efforts, we introduced a number of new families in recent years, including the Stratix V (including E, GX, GS and GT), Stratix IV (including E, GX and GT), Stratix III, Cyclone V, Cyclone IV (including E and GX), Cyclone III, Arria V, Arria II GX, MAX V, MAX II, HardCopy IV and HardCopy III device families, as well as major enhancements to our IP core offerings and the Quartus II development platform.

Our research and development costs, which are charged to expense as incurred, were $264.6 million in 2010, $260.2 million in 2009, and $257.7 million in 2008.

Patents, Trademarks, and Licenses

We rely on intellectual property laws-including patent, copyright, trademark, and trade secret laws-to establish and maintain our proprietary rights in products and technology. Activities include:


•	Patents - As of December 31, 2010, we owned more than 2,280 United States and 260 foreign patents. We also had more than 1,090 patent applications pending worldwide.


•	Trademarks - We use, register, and apply to register certain trademarks and service marks in the United States and foreign countries.


•	Product registrations - We file registrations in the United States under the Semiconductor Chip Protection Act to protect our chip designs.


•	When appropriate, we file lawsuits to protect our intellectual property rights.

We have also licensed technology that allows us to design, manufacture, and sell products using certain intellectual property owned by others.

Marketing and Sales

We market our products worldwide through a network of distributors, independent sales representatives, and direct sales personnel.

ALTERA DISTRIBUTORS

In all of the major geographic markets that we serve, we work with distributors to provide demand creation for the broad customer base and order-fulfillment services for most of our customers. These distributors are franchised by component manufacturers to sell a wide variety of products to many customers, and they may sell competing products or solutions. We have contracts with our distributors that can be terminated by either party upon notice.

All of our distributors stock inventory of our products. Distributors purchase products from us at a set distributor cost denominated in U.S. dollars. Title and risk of loss transfer upon shipment from our stocking locations, which are located in the Asia Pacific region at the independent subcontractors we employ for test and assembly services or at our warehouse in San Jose. When products are shipped to a distributor, we defer revenue on the sale until the distributor sells the products in accordance with our revenue recognition policy. Consequently, the deferred revenue and the corresponding deferred cost of sales are recorded as a current liability under the caption Deferred income and allowances on sales to distributors. All payments to us are denominated in U.S. dollars. For a detailed discussion of our revenue recognition policy, see Note 2 - Significant Accounting Policies - Revenue Recognition to our consolidated financial statements.

Our sales cycle begins with a “design-win” phase, which can be lengthy, is not always certain and often requires the ongoing participation of sales, engineering, and managerial personnel. Once customer demand has been created and a design is ready to move to prototyping or production, the order-fulfillment process begins. Customer orders are primarily processed and fulfilled by a local distributor. For these orders, our distributors are the legal sellers of the products and therefore bear all risks related to the sale of commercial goods, such as credit loss, inventory shrinkage and theft, and foreign currency fluctuations. For certain arrangements, Altera drop ships products to fulfill orders processed through our primary distributor.

Our distributors periodically return certain amounts of unsold product and receive price concessions for unsold product if we reduce prices. For high-volume or competitive situations, we often provide price concessions to our distributors. A customer purchasing a small quantity of product from a distributor usually pays list price. However, a customer using our products in volume production, purchasing thousands or even hundreds of thousands of units, will often negotiate a substantial price discount from the distributor. Under these circumstances, the distributor will often negotiate and receive a price concession from Altera. These price concessions are negotiated in U.S. dollars. Average aggregate price concessions typically range from 65% to 80% of our list price on an annual basis, depending upon the composition of our sales, volume and factors associated with timing. This is a standard practice in the semiconductor industry, and we generally provide some level of price concession to every distributor.

Our net sales are the sum of our own direct sales to original equipment manufacturers, or OEMs, plus our distributors' resale of Altera products. For 2010, 2009 and 2008, worldwide sales through distributors for subsequent resale to OEMs or their subcontract manufacturers accounted for 81%, 82% and 91% respectively, of our net sales. Arrow Electronics, Inc. including its affiliates (“Arrow”), our largest distributor, accounted for 46% of our net sales in 2010, 45% in 2009 and 46% in 2008. Our second largest distributor, Macnica, Inc. including its affiliates (“Macnica”), accounted for 20% of our net sales in 2010, 15% in 2009, and 14% in 2008. No other distributor accounted for more than 10% of our net sales in 2010, 2009 or 2008.

See Note 4 - Accounts Receivable, Net and Significant Customers to our consolidated financial statements.

ALTERA SALES, MARKETING, AND CUSTOMER SUPPORT

Altera has a dedicated global sales and marketing organization to create customer demand and manage our network of distributors and independent sales representatives. We focus our direct demand creation efforts on a limited number of key accounts, and provide technical, business, and marketing support to distributors and independent sales representatives. Independent sales representatives, who are mostly located in North America and in select European countries, create demand and provide customer support in a defined territory and often with a defined set of customers. They do not stock inventory or fulfill orders. All of our contracts with independent sales representatives can be terminated by either party upon notice.

Customer support and service are important to selling and marketing our products. We provide several levels of technical support, including application assistance, design services, and customer training. We also publish data sheets and application notes, conduct technical seminars, and provide design assistance to customers via the Internet and electronic links.

We have domestic sales offices in numerous major metropolitan areas throughout the United States, and we maintain international sales support offices in Bangalore, Beijing, Cork, Chengdu, Helsinki, Hong Kong, London, Munich, Osaka, Ottawa, Paris, Seoul, Shanghai, Shenzhen, Singapore, Stockholm, Taipei, Tokyo, Toronto and Turin.

Huawei Technologies Co., Ltd. (“Huawei”), an OEM, individually accounted for 13% of net sales in 2010, and 11% in 2009. No other individual OEM accounted for more than 10% of net sales in 2010 or 2009. No single end customer accounted for more than 10% of net sales in 2008. See Note 4 - Accounts Receivable, Net and Significant Customers to our consolidated financial statements.

INTERNATIONAL SALES

Sales outside of the U.S. and Canada constituted 81% of net sales in 2010, 80% of net sales in 2009, and 77% of net sales in 2008. Sales to Japan accounted for 16% of net sales in 2010, 18% of net sales in 2009, and 19% of net sales in 2008. Sales to China accounted for 33% of net sales in 2010, 27% of net sales in 2009, and 19% of net sales in 2008. Except for the United States, China, and Japan, no other country accounted for sales in excess of 10% of net sales during 2010, 2009 or 2008. For a detailed description of our sales by geographic region, see Item 7: Results of Operations - Sales by Geography, and Note 14 - Segment and Geographic Information to our consolidated financial statements.

Backlog

Our backlog consists mostly of distributor orders, as well as limited OEM orders, that are for delivery within the next three months. Our backlog of orders as of December 31, 2010, was approximately $2.0 billion, compared to $1.6 billion as of December 31, 2009.

Historically, backlog is a poor predictor of future sales or customer demand for the following reasons:


•	While our backlog increases during periods of high demand and supply constraints, in most cases, purchasers may cancel product orders up to 30 days before the scheduled delivery date without incurring significant cancellation penalties.


•	Our backlog is valued at list price, which in most cases is substantially higher than the price ultimately recognized as revenue.

Manufacturing

WAFER SUPPLY

Die, cut from silicon wafers, are the essential components of all our devices and comprise a significant portion of the total device cost. Our manufacturing strategy is known as a “fabless” business model since we purchase our silicon wafers from independent semiconductor foundries instead of manufacturing them ourselves. This strategy allows us to take advantage of these suppliers' economies of scale and gives us direct and timely access to advanced process technology. We purchase nearly all of our silicon wafers from Taiwan Semiconductor Manufacturing Company (“TSMC”), an independent semiconductor foundry. We have no formalized long-term supply or allocation commitments from TSMC. In the past, we have used other foundry vendors, and we may establish additional foundry relationships as they become economically beneficial or technically necessary.

TESTING AND ASSEMBLY

After wafer manufacturing is completed, each silicon wafer is tested using a variety of test and handling equipment that is owned by us and consigned to our partners. The vast majority of our silicon wafer testing is performed at TSMC. Our San Jose facility is used primarily for new product development.

The wafers are then shipped to various assembly suppliers in Asia, where they are divided into good die and encapsulated in packages. We use a number of independent assembly suppliers to take advantage of their economies of scale and supply flexibility, and to give us direct and timely access to advanced packaging technology. We purchase almost all of our assembly services from Amkor Electronics, Inc. (“Amkor”), in Korea and the Philippines, and Advanced Semiconductor Engineering, Inc. (“ASE”) in Malaysia and Taiwan.

Following assembly, each packaged unit completes final testing, marking, and inspection before being packaged for storage as finished goods. We also use Amkor and ASE for almost all of our final test and back-end operation services. These suppliers

perform final testing using our proprietary test software operating on hardware that is consigned to or owned by our suppliers.

The majority of our inventory, including finished goods, is warehoused in Asia at our subcontract test and assembly partners with a smaller portion located at our corporate facility in San Jose, California. These suppliers also ship our products to OEMs and distributors.

ITEM 1A. RISK FACTORS.

The following risk factors, among others that are not presently known or that we currently believe unimportant, could affect our future results and could cause our actual results to differ materially from those expressed in our forward-looking statements. Before you decide to buy, hold, or sell our common stock, you should carefully consider these risks, in addition to the other information contained in this report. Our business, financial condition, and operations results could be seriously harmed if any of the events described here actually occurs. In that situation, the market price for our common stock could decline, and you may lose all or part of your investment.

Our financial results are affected by general economic conditions and the highly cyclical nature of the semiconductor industry.

Semiconductor companies, such as Altera, experience significant fluctuations in sales and profitability. The semiconductor industry has experienced economic downturns and business contractions from time to time, which can be severe and prolonged. The fluctuations follow the turns of the global economy and in a downturn can result in significant reductions in product demand and excess customer inventories. Global economic weakness or cyclical downturns have previously resulted from periods of economic recession, reduced access to credit markets, weakening or strengthening of the U.S. dollar relative to other currencies, weak end-user demand, excess industry capacity or general reductions in inventory levels by customers. It is difficult for our customers, our vendors and us to accurately forecast and plan future business activities in today's global economy.

Our ability to predict the quantity and type of products our customers will need in the future is challenging because our customers face volatile pricing and unpredictable demand for their own products and are increasingly focused on cash

preservation and tighter inventory management. These factors could affect the timing of customer orders and the overall level of demand for our products. Because it is extremely difficult to forecast the success or timing of a customer's product, and because our end markets are highly fragmented (we have over 13,000 PLD customers), our ability to forecast end customer demand is difficult. If we overestimate customer demand, we may allocate resources to manufacturing products that we may not be able to sell as quickly as estimated, if at all. As a result we could hold excess or obsolete inventory, which would reduce our profit margins and adversely affect our financial results.

The volatility and disruption of the capital and credit markets and adverse changes in the global economy may negatively impact our customers' business and their ability to access financing, which could adversely affect demand for our products. Our operating cash flows are highly dependent on the continued collection of receivables and our ability to sell inventories. Declines in overall economic conditions could lead to deterioration in the quality of our receivables. In addition to reductions in sales and elevated risk associated with the collection of receivables, our profitability and cash flows may suffer during downturns because we may not be able to reduce costs at the same rate as our sales decline.

As further described below, we depend entirely on independent subcontractors to supply us with finished silicon wafers and to assemble, test and ship our semiconductor products. Uncertainties in the capital and credit market, however, may adversely affect the ability of our suppliers to obtain financing for operations. If our subcontractors' capital structures weaken, they may fail to satisfy our demand and our business could be materially disrupted.

If global economic and market conditions remain uncertain or persist, spread or deteriorate further, we could experience a material impact on our business, financial condition, results of operations or cash flows.

Our gross margins are subject to fluctuations due to many factors.

Our gross margins may fluctuate due to many factors, including:


•	Vertical market pricing mix


•	Changes in the mix of our prototyping and production-based business


•	Competitive pricing dynamics and customer mix


•	Various manufacturing cost variables including product yields, wafer prices, package and assembly costs, provisions for excess and obsolete inventory, and absorption of manufacturing overhead

Additionally, since the majority of our sales are booked and shipped through our distributors within the same quarter, forecasting our gross margins is difficult.

Our failure to compete successfully in the highly competitive semiconductor industry would adversely affect our financial results and business prospects.

The semiconductor industry, including the PLD market, is intensely competitive. Our ability to compete successfully in the semiconductor industry depends on our ability to provide our customers with solutions providing greater value than those offered by competing programmable logic vendors, such as Xilinx and Lattice, and other semiconductor companies that indirectly compete with us. Because we develop PLDs for applications that are presently served by ASIC, ASSP, FPGA, CPLD, digital signal processing (“DSP”), and microprocessor/microcontroller vendors, we compete against these vendors.

To the extent that our efforts to compete are not successful, our financial condition and results of operations could be materially adversely affected. Other competitors include manufacturers of:


•	high-density programmable logic products characterized by FPGA-type architectures


•	high-volume and low-cost FPGAs as programmable replacements for ASICs and ASSPs


•	ASICs and ASSPs with incremental amounts of embedded programmable logic


•	high-speed, low-density CPLDs


•	high-performance DSP devices


•	products with embedded multi-gigabit transceivers


•	other new or emerging programmable logic products

Many of these competitors have substantially more financial, technical, and marketing resources than we do and have well-established market positions and solutions that have proven technically feasible and economically competitive over several decades. We may be unable to displace these vendors in the targeted applications and densities. Several companies have introduced products that compete with ours or have announced their intention to sell PLD products. The benefits of

programmable logic have attracted a number of competitors to this segment. We recognize that different applications require different programmable technologies, and we are developing architectures, processes and products to meet these varying customer needs. Recognizing the increasing importance of standard software solutions, we have developed common software design tools that support the full range of our IC products. We believe that automation and ease of design are significant competitive factors in this segment.

The highly competitive environment of the semiconductor industry and the high costs associated with manufacturing technologies and developing marketable products have resulted in significant consolidation in the industry and are likely to lead to further consolidation in the future. We recently acquired all of the outstanding equity of Avalon Microelectronics, Inc., a leading provider of FPGA-based Optical Transport Network solutions. We may continue to pursue business combination opportunities to improve our market share and the applications and products we can market. However, we may be outbid for the best assets. We also may become a target for a company looking to improve its competitive position. Such an occurrence may take place at any time with consequences that may not be predictable and that could have a materially adverse effect on our results of operations and financial condition.

A downturn in the communications equipment end market could cause a reduction in demand for our products and limit our ability to maintain revenue levels and operating results.

Approximately 44% of our net sales for 2010 was derived from customers participating in the telecom and wireless vertical market. In the past, a general weakening in demand for programmable logic products from customers in the communications end market has adversely affected our revenue. Any deterioration in the communication end market or reduction in capital spending to support this end market could lead to a reduction in demand for our products and could adversely affect our revenue and results of operations.

The length of our design-in and sales cycles could affect our ability to forecast future sales.

Our sales depend on our products being designed into end customers' products, and on those products being produced in volume. Our products are very complex, and the time from design-in to volume production ranges from six months to three years or more. From initial product design-in to volume production, many factors can affect the timing and/or volume of our sales. These factors include, but are not limited to, changes in the competitive position of our technology, the competitiveness of our end customers' products in the markets they serve, our customers' financial stability, end customer program delays and cancellations, and our ability to ship products according to customer schedules.

Our business is characterized by a general decline in semiconductor product selling prices that may materially and adversely affect our profitability.

The selling prices of our products have decreased over time. We have offset the selling price decreases by reducing manufacturing costs, improving yields, and increasing unit sales. However, our ongoing efforts may not be successful or may not keep pace with the anticipated, continued decline in product selling prices, which could ultimately reduce revenues and gross margins.

Because we depend on international sales for a majority of our total sales, we may be subject to political, economic, and other conditions that could increase our operating expenses and disrupt our business.

Our operations outside of the United States are subject to risks that are inherent in conducting business under non-U.S. laws, regulations and customs. During 2010, sales outside of the U.S. and Canada constituted approximately 81% of our net sales, and we expect that international sales will continue to account for a significant portion of our net sales. Risks related to our foreign operations include:


•	Unfavorable economic, market, political, and social conditions in a specific country or region


•	Fluctuation in foreign currency exchange rates


•	Adverse changes in tax laws


•	Increased freight costs


•	Interruptions in air transportation


•	Reduced protection for intellectual property rights in some countries


•	Longer receivable collection periods


•	Natural or man-made disasters in the countries or regions where we sell our products


•	Different labor regulations

Our business must comply with a variety of foreign laws and take risks associated with legislation and regulations for importing and exporting semiconductor products. In the future, the United States or other countries may impose quotas, duties, tariffs, taxes, or other charges, restrictions, or trade barriers for the import or export of our products.

We rely heavily on distributors to generate a significant portion of our sales and fulfill our customer orders. The failure of our distributors to perform as expected could materially reduce our future sales.

Worldwide sales through distributors accounted for 81% of our net sales during 2010. We rely on many distributors to help us create end customer demand, provide technical support and other value-added services to end customers, fill customer orders, and stock our products. Our contracts with our distributors may be terminated by either party upon notice.

Our distributors are located all over the world and are of various sizes and financial conditions. Lower sales, lower earnings, debt downgrades, the inability to access capital markets, and higher interest rates could potentially affect our distributors' operations.

We are highly dependent on Arrow Electronics, Inc. including its affiliates (“Arrow”), in many locations across the world, particularly in North America.

During 2010, Arrow accounted for approximately 46% of net sales on a worldwide basis, while our next-largest distributor, Macnica, Inc. including its affiliates (“Macnica”), accounted for approximately 20% of net sales. As of December 31, 2010, accounts receivable from Arrow and Macnica individually accounted for 18% and 51%, respectively, of our total accounts receivable.

Our ability to add or replace distributors is limited.

Our distributors are contracted by Altera to perform two primary, yet distinct, functions that are difficult to replace:


•	Distributors provide logistics support, such as order entry, credit, forecasting, inventory management, and shipment of product, to end customers. The process of integrating systems to allow for electronic data interchange is complex and can be time consuming.


•	Distributors create demand for our products at the engineering level. This mandates the training of an extended distributor sales force, as well as hiring and training specialized applications engineers skilled in promoting and servicing products at the engineering level.

In addition, our distributors' expertise in the determination and stocking of acceptable inventory levels may not be easily transferable to a new distributor. Also, end customers may be hesitant to accept the addition or replacement of a distributor.

We depend entirely on independent subcontractors to supply us with finished silicon wafers. The failure of these subcontractors to satisfy our demand could materially disrupt our business.

Nearly all of our silicon wafers are produced by TSMC in its manufacturing facilities located primarily in Taiwan and the U.S. Silicon wafer production facilities have a fixed capacity that is allocated solely by our vendors and beyond our direct control. We have no formalized long-term supply or allocation commitments from our foundry suppliers. Our operations would be disrupted if TSMC ended its relationship with us and we were unable to arrange a satisfactory and cost-effective alternative to quickly fulfill customer orders.

To ensure continued wafer supply, we may establish other wafer supply sources as these arrangements become economically advantageous or technically necessary. However, only a few foundry vendors have the capability to manufacture our most advanced products. If we engage alternative supply sources, we may encounter start-up difficulties and incur additional costs. In addition, shipments could be significantly delayed while these sources are qualified for volume production.

Furthermore, because we rely on third-party foundries, we have little or no direct control over production costs, delivery schedules, and wafer quality. We also face increased exposure to potential misappropriation of our intellectual property.

Wafer shortages and/or increased wafer and assembly material costs could lower our gross margins, reduce our sales, or otherwise materially disrupt our business.

If market demand for silicon wafers or assembly material suddenly exceeds market supply, our supply of silicon wafers or assembly material could quickly become limited. A shortage in manufacturing capacity could hinder our ability to meet product

demand. Moreover, silicon wafers constitute more than half of our product cost. If we are unable to purchase wafers at favorable prices, our gross margins will be adversely affected.

Product manufacturing is complex, and our foundries may not achieve the necessary yields or product reliability that our business requires.

Manufacturing our products is a highly complex and precise process, requiring production in a tightly controlled environment. We depend not only on sufficient foundry manufacturing capacity and wafer prices, but also good production yields (the number of good die per wafer) and timely wafer delivery to meet customer demand and maintain profit margins. Wafer production yields depend on a wide variety of factors including the level of contaminants in the manufacturing environment, impurities in the materials used, and the performance of personnel and equipment. As a result, we may experience problems with achieving acceptable production yields and timely delivery from our foundry vendor.

Difficulties in production yields can often occur when we begin new product production, when we transition to new processes, or when our principal wafer supplier, TSMC, moves production of a product from one manufacturing plant to another, or manufactures the same product at multiple factories. As a result of manufacturing defects, TSMC has also occasionally scrapped wafers, resulting in longer manufacturing lead times. Further, production throughput times vary considerably among the various factories used by our wafer suppliers, and we may occasionally experience production delays. These difficulties and delays can potentially cause significantly higher costs and lower product availability.

We depend on independent subcontractors, located in Asia, to assemble, test, and ship our semiconductor products. The failure of these subcontractors to satisfy our demand could materially disrupt our business.

Because we rely on independent subcontractors to assemble, test, and ship our semiconductor products and to provide package piece parts, we cannot directly control our product delivery schedules or quality levels. We are dependent upon sufficient subcontractor assembly and test capacities, both in raw materials and services, to meet the demand for our own products. Our future success also depends on the financial viability of our independent subcontractors. If market demand for subcontractor material and services exceeds available supply or if the subcontractors' capital structures weaken, we may experience product shortages, quality assurance problems, and/or increased manufacturing costs.

Conditions outside the control of our independent subcontractors and distributors may impact their business operations and thereby adversely interrupt our manufacturing and sales processes.

The economic, market, social, and political situations in countries where certain independent subcontractors and distributors are located are unpredictable, can be volatile, and can have a significant impact on our business because we may be unable to obtain or distribute product in a timely manner. Market and political conditions, including currency fluctuation, terrorism, political strife, war, labor disruption, and other factors, including natural or man-made disasters, adverse changes in tax laws, tariff, import or export quotas, power and water shortages, or interruption in air transportation, in areas where our independent subcontractors and distributors are located also could have a severe negative impact on our operating capabilities.

Our failure to define, develop, and manufacture technologically advanced products would adversely affect the success and growth of our company.

We operate in a dynamic market characterized by rapid technological change. Our products are manufactured using a highly complex and precise process, requiring production in a tightly controlled environment. Our current product development efforts focus on developing new PLDs, related development software and hardware, and advanced semiconductor wafer fabrication processes. Our development efforts may impact the timely introduction of competitive new products or product enhancements. Additionally, we may not be successful in developing new products or using and converting established products to new and more advanced process technologies. For example, our current generation product families, the Stratix V (including E, GX, GS and GT) families, are manufactured on a 28-nanometer process technology, but our next-generation product families will be manufactured on smaller circuit geometries that we have not used before. The use of advanced process technology has technological risks and start-up difficulties that can adversely affect research and development spending, yields, product costs, and product delivery timeliness.

Any prolonged disruption to our global communications infrastructure could impair our ability to plan factory activity and respond to customer demand.

Demand for our products is highly volatile, especially at the detailed ordering code level. To achieve short delivery lead times and superior levels of customer service while maintaining low levels of inventory, we constantly adjust our manufacturing

subcontractors' production schedules. We develop and adjust these schedules based on end customer demand as communicated by our distributors and based on our inventory levels, manufacturing cycle times, component lead times, and projected production yields. We combine and distribute all of this information electronically over a complex global communications network. Our ability to estimate demand and to adjust our production schedules is highly dependent on this network; we have no manual back-up. A prolonged disruption or service failure in a portion of this network would impair our ability to plan factory activity and respond to demand.

Product quality problems could lead to reduced revenue, gross margins, and net income.

We produce highly complex hardware and software products that incorporate leading-edge technology. Our pre-shipment testing programs may not detect all defects. Because our product warranties against materials and workmanship defects and non-conformance to our specifications are for varying lengths of time, we have occasionally been required to replace components or refund the purchase price paid due to product defects. If the costs for customer or warranty claims increase significantly compared with our historical experience, our revenue, gross margins, and net income may be adversely affected. For example, if we cannot fix a product defect in a timely manner, we may incur product reengineering expenses, increased inventory costs, or damage to our reputation, any of which could materially affect our revenue, gross margins, and net income.

We may be subject to product liability claims.

Our devices are used in automotive, military, aerospace, avionics, medical equipment, and other systems where system failure could cause damage to property or people. We may receive product liability claims if our devices cause system failures. Based on our historical experience, we believe that the risk of exposure to product liability claims is currently low, but could be higher if both the sales volume in these applications and the frequency of system failures caused by our devices increases.

Our business is subject to the risks of earthquakes and other catastrophic events.

Our corporate headquarters in San Jose, California is located near major earthquake faults. Some of our international facilities and those of our key suppliers, including TSMC which produces nearly all of our silicon wafers, are also located near major earthquake faults. Any catastrophic event, such as an earthquake or other natural disaster, could make it difficult for Altera and our independent subcontractors to meet product design deadlines, maintain our records, pay our suppliers, or manufacture or ship our products.

As we carry only limited insurance coverage, any incurred liability resulting from uncovered claims could adversely affect our financial condition and operating results.

Our insurance policies may not be adequate to fully offset losses from covered incidents, and we do not have coverage for certain losses. We believe our existing insurance coverage is consistent with common practice and economic and availability considerations. If our insurance coverage is inadequate to protect us against unforeseen catastrophic losses, any uncovered losses could adversely affect our financial condition and operating results.

Legislative action in the United States could materially and adversely affect us from a tax perspective.

Legislative action may be taken by the U.S. Congress which, if ultimately enacted, would adversely affect our effective tax rate and/or require us to take further action, at potentially significant expense, to seek to preserve our effective tax rate. The current administration and Congress have announced proposals for new U.S. tax legislation that, if adopted, could substantially modify the rules governing the U.S. taxation of certain non-U.S. affiliates. The potential changes include, but are not limited to, curbing the deferral of U.S. taxation of certain foreign earnings and limiting the ability to use foreign tax credits. We cannot predict the outcome of any specific legislative proposals. However, any of these changes could have a material adverse affect on our profitability.

We may not be able to maintain a competitive worldwide effective corporate tax rate.

We cannot give any assurance as to what our effective tax rate will be because of, among other things, uncertainty regarding the tax policies of the jurisdictions where we operate. As a result, our actual effective tax rate may vary from our expectations and that variance may be material. Additionally, the tax laws of the jurisdictions in which we operate could change in the future, and such changes could cause a material change in our effective tax rate.

The failure of our intellectual property rights to provide meaningful protection from our competitors could harm our competitive position.

We rely on patent, trademark, trade secret, copyright, and mask work laws to protect our intellectual property, proprietary information, and technology rights. As of December 31, 2010, we owned more than 2,280 U.S. patents and 260 foreign patents, and had more than 1,090 patents applications pending worldwide. Our patents and patent applications may not protect us from our competition, which may be able to circumvent our patents or develop new patentable technologies that displace our products. In addition, other parties, including our former employees or consultants, may try to disclose, obtain, or use our proprietary information or technologies without our authorization despite our best efforts at prevention. If other companies obtain this information or develop similar information or technologies, they may develop products that compete against ours.

Moreover, the laws of certain countries where we sell, manufacture, or distribute products may not protect our products and intellectual property rights to the same extent as U.S. laws. Policing the unauthorized use of our products is difficult and costly and could divert the efforts of our technical and management personnel. Even if we spend significant resources and efforts to protect our intellectual property, we may be unable to prevent misappropriation of our technology. If others use our proprietary rights, it could materially harm our business and require expensive litigation to enforce our intellectual property rights.

Intellectual property infringement claims could adversely affect our ability to manufacture and market our products.

We occasionally receive inquiries about possible patent infringements that may require us to obtain licenses relating to our current or future products. We may be unable to obtain licenses on reasonable terms, or the license agreements may have set durations or may not provide complete protection against infringement claims involving all of our current or future products. If we are sued for patent infringement, the costs and outcome of litigation will be unpredictable and may have a negative impact on our financial results. Intellectual property claims, regardless of their merit, can result in costly litigation and divert the efforts of our technical and management personnel. Legal proceedings are also unpredictable and may be affected by events outside of our control. If our defense against intellectual property infringement claims is unsuccessful, we may be required to pay significant monetary damages or be subject to an injunction against the manufacture and sale of one or more of our product families. Alternatively, we could be required to spend significant resources to develop non-infringing technology, the success of which may be uncertain. Intellectual property litigation may have an adverse effect on our financial position, results of operations, and cash flows.

ITEM 1B. UNRESOLVED STAFF COMMENTS.

None.

ITEM 2. PROPERTIES.

Our headquarters facility currently consists of four interconnected buildings totaling approximately 500,000 square feet, located on approximately 25 acres of land that we own in San Jose, California. Design, research, marketing, administrative, and limited manufacturing activities are performed in this facility. We also have a 465,000-square-foot design, test engineering, operation and administrative facility in Penang, Malaysia, located on land leased on a long-term basis. Also, we lease our domestic and international offices, including our technology centers in the United Kingdom and Toronto, Canada. We believe that our facilities are adequate for our current and foreseeable future needs.

ITEM 3. LEGAL PROCEEDINGS.

We are named as a party to a lawsuit concerning our historical stock option practices and related accounting and reporting.

In May and July 2006, we were notified that three shareholder derivative lawsuits had been filed in the Superior Court of the State of California, County of Santa Clara, by persons identifying themselves as Altera shareholders and purporting to act on behalf of Altera, naming Altera Corporation as a nominal defendant and naming some of our current and former officers and directors as defendants. On July 12, 2006, one of these derivative actions was voluntarily dismissed by the plaintiff shareholder. The remaining two derivative lawsuits pending in Santa Clara Superior Court were consolidated into a single action on September 5, 2006. Plaintiffs filed a second amended consolidated complaint on December 15, 2006. On January 30, 2007, Altera and the defendants filed a motion to stay this action pending resolution of the federal derivative action (discussed below). On February 11, 2009, one of the remaining derivative plaintiffs voluntarily dismissed his derivative claims and, on March 20, 2009, the other remaining derivative plaintiff filed a third amended complaint. In June 2009, Altera and the defendants demurred to the third amended complaint. After the court issued a tentative ruling in favor of Altera, the parties agreed to stay the action in order to allow plaintiff to serve a demand on Altera's board of directors. The plaintiff served the demand on November 4, 2009. In the first quarter of 2010, the board of directors completed its review of the demand and decided to reject plantiff's demand. On June 1, 2010, the plaintiff filed a fourth amended complaint, alleging that the board of director’s decision to reject plaintiff’s demand was wrongful. On July 15, 2010, Altera demurred to the fourth amended complaint. In October 2010, the court dismissed plaintiff's fourth amended complaint and granted plaintiff leave to file a fifth amended complaint. On November 4, 2010, the plaintiff filed a fifth amended complaint, alleging that Altera's board of directors wrongfully refused his demand. On December 10, 2010, Altera, joined by the individual defendants, demurred to the fifth amended complaint.

Plaintiff asserts claims against the individual defendants for breach of fiduciary duty, waste of corporate assets, unjust enrichment, violations of California Corporation Code section 25402, breach of fiduciary duty for insider selling and misappropriation of information, and deceit. Plaintiff's claims concern the granting of stock options by Altera between 1994 and 2001 and the alleged filing of false and misleading financial statements between 1994 and 2006. All of these claims are asserted derivatively on behalf of Altera. Plaintiff seeks, among other relief, an indeterminate amount of damages from the individual defendants and a judgment directing Altera to reform its corporate governance practices.

During the months of May, June, and July 2006, four other derivative lawsuits were filed by purported Altera shareholders, on behalf of Altera, in the United States District Court for the Northern District of California. On August 8, 2006, these actions were consolidated, and the plaintiffs filed a consolidated complaint on November 30, 2006. On September 15, 2008, the plaintiffs voluntarily agreed to dismiss the case. On September 18, 2008, the court entered an order dismissing the case.

On December 8, 2010, Intellectual Ventures I LLC and Intellectual Ventures II LLC (“Intellectual Ventures”) filed a lawsuit in the United States District Court for the District of Delaware against Altera, Microsemi Corporation, and Lattice Semiconductor Corporation alleging that Altera is infringing five patents. The complaint requests unspecified monetary damages including enhanced damages for willful infringement.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis should be read in conjunction with our consolidated financial statements and related notes thereto included in Item 8 and the Risk Factors included in Item 1A of this annual report.

Executive Overview

Company and Market Overview

We are a global semiconductor company, serving over 13,000 customers within the Telecom and Wireless, Industrial Automation, Military and Automotive, Networking, Computer and Storage, and Other market segments. The Other market segment includes sub-segments of broadcast, consumer, medical and test. We design, manufacture, and market a variety of products:


•	Programmable logic devices (“PLDs”), which consist of field-programmable gate arrays (“FPGAs”) and complex programmable logic devices (“CPLDs”), are standard semiconductor integrated circuits, or chips, that our customers program to perform desired logic functions in their electronic systems.


•	HardCopy application-specific integrated circuit (“ASIC”) devices transition customer designs from high-density FPGAs to low-cost non-programmable devices for volume production.


•	Pre-defined design building blocks, known as intellectual property (“IP”) cores, can be licensed by customers to easily implement standard functions in their PLD designs.


•	Proprietary development software, which operates on personal computers and engineering workstations, is used by customers to develop, compile, and verify their designs, and then program their designs into our PLDs.

In 2010, sales of PLDs generated 94% of our net sales, with FPGA and CPLD sales comprising approximately 82% and 12% of our net sales, respectively. The remainder of our sales is comprised of our HardCopy devices and configuration devices used in conjunction with our FPGAs, as well as licensing of IP cores and proprietary development tools.

Market Opportunity

Based on publicly available data and information derived from Gartner Dataquest, we estimate that the PLD market was approximately $4.8 billion in 2010. We also estimate that the combined ASIC and ASSP market in 2010 was approximately $97.0 billion, comprised of the ASIC market at approximately $22.0 billion and the ASSP market at approximately $75.0 billion. Due to the low priced nature of some very high volume ASIC and ASSP applications, including mobile phones and certain consumer applications such as PC-related equipment, video games and portable media applications, we do not believe that the entire ASIC and ASSP market is available for displacement by PLDs. As such, we estimate that the PLD accessible ASIC and ASSP market was approximately $38.0 billion in 2010 ($11.0 billion in accessible ASICs and $27.0 billion in accessible ASSPs) and that this represents significant PLD growth potential.

In addition to the accessible portion of the ASIC and ASSP market of $38.0 billion in 2010, our Embedded Initiative, which is a strategy to displace embedded processors and microcontrollers by integrating them within our FPGAs, offers an additional growth opportunity of approximately $9.0 billion. By investing in and developing software, hard and soft IP, as well as application-targeted FPGAs, we believe that we can capture a higher percentage of the semiconductor bill of materials in an embedded system. With a combined $47.0 billion ASIC, ASSP and embedded market replacement opportunity, our goal is that, over time, the average growth rate of our revenue can double that of the total semiconductor industry.

For our most current designs, PLD process technology is typically two or three process generations more advanced than ASIC and ASSP process technology. As chip manufacturing becomes more advanced, the total cost of chip development increases, reducing the cost advantage of ASICs and ASSPs. As a result, some ASIC and ASSP suppliers choose to use non-leading-edge process technology for new designs to reduce development costs. We believe this has brought us to a “tipping point” with respect to our opportunity to displace ASICs and ASSPs. It may no longer be technologically feasible for many ASIC and ASSP suppliers to continue to use old process generations for technically advanced systems, and at the same time it may not be economically feasible for them to use new generations of technology for low and mid-range volume applications. The “process technology gap” between PLDs and ASIC and ASSP alternatives will increase over time and, when combined with the traditional PLD advantages of greater flexibility, lower development cost, and faster time-to-market, should drive the

accelerated adoption of PLDs in the years ahead. We have seen evidence of the tipping point as an increasing number of ASIC and ASSP opportunities are being displaced by Stratix IV FPGAs and, to date, the Stratix IV family has been the fastest ramping FPGA product in the history of the PLD industry. We believe our 28-nm-based Stratix V FPGAs, which we will begin shipping in early 2011, will further widen the technology gap between PLDs and ASICs and ASSPs, and drive increases in the rate of adoption of PLDs from ASICs and ASSPs.

While we have had some degree of success winning customer designs over ASICs, ASSPs, embedded processors and microcontrollers, the rate at which customers will adopt the use of PLDs is unclear. Technological issues including those related to power consumption, performance specifications and design methodology, may inhibit some customers from the broad adoption of PLDs. Despite having success in winning new designs and a potentially higher average growth rate of PLDs relative to ASICs, ASSPs, embedded processors and microcontrollers, our share gains versus these alternatives may take many years to become significant due to the small size of the PLD market when compared to the combined accessible revenue of ASICs, ASSPs, embedded processors and microcontrollers. This is compounded by the fact that it may take a very long period of time for revenue from new designs to become meaningful when compared to the existing legacy revenue stream.

Driving Operational Excellence

Since the PLD market was created in the 1980s, the financial business models of the leading PLD suppliers have generally been favorable when compared to most other semiconductor companies. Fabless strategies, high barriers to entry, and proprietary architectures have helped drive strong financial results for PLD suppliers.

We regularly engage in a strategic review of our business to improve operations and financial returns. We are focused on maximizing return on invested capital by pursuing greater efficiencies in all aspects of our operations while seeking balance with our commitment to continued investment in advanced technology for the development of new products. In recent years, we have increased our focus on enhancing our business model to simplify our business processes while also growing PLD market share.

We believe that our early and continued focus on cost reduction and productivity enhancement before the business slowdown related to the global financial crisis during 2008 and 2009 provided us with some benefits compared to other semiconductor companies. Our ability to maintain investment in the research and development of future products, which has been aided by our early and ongoing cost savings initiatives, is a vital factor for our future sales and earnings growth. In addition, our prior work in analyzing business processes has not only allowed us to effectively identify and implement simplification and cost reduction initiatives, but the concept of “workflow efficiency” has become a valued aspect of our business culture.

Leveraging Our Global Structure

We believe that we have opportunities to further expand our position outside of the United States. Our organization and management structure integrates our U.S. and non-U.S. operations and provides our management team with a global perspective on our markets. We believe that this infrastructure provides opportunities to develop and commercialize new products that meet global needs and can be rapidly launched in multiple markets. Our global organizational focus should allow us to continue to grow outside of the United States faster than within the United States.

Competing for Design Wins

We compete with other PLD vendors to displace fixed-chip logic alternatives and for market share within the PLD market. Competition between PLD vendors is most intense in the “design-win” phase of the customer's design, when customers select products for use in the customer's electronic system. A customer has a tendency to use products from the same PLD vendor as was used on the most recent design. This "incumbency advantage" is driven by a customer's investment in building expertise with the PLD vendor's software. In addition, because each PLD vendor's products are proprietary, the cost to switch PLDs after a system has been designed and prototyped is very high. Therefore, a design win can provide the PLD vendor with a profitable revenue stream through the life of the customer's program.

From the time a design win is secured, it can be two or more years before a customer starts volume production of its system. Typically, the customer selects the PLD vendor relatively early in a customer's design process, but it may take several years to complete system design, build prototypes, sample the marketplace for customer acceptance, make modifications, and manufacture in volume. Thus, there is a delay between developing a competitive advantage and experiencing a shift in the PLD market, meaning that market share is a lagging indicator of relative competitive strength. Because it is extremely difficult to forecast the success and timing of customer programs, and because the end markets are highly fragmented (we have over 13,000 PLD customers), it is difficult even for PLD vendors to gauge their own competitive strength in winning designs at a

particular point in time.

Developing Competitive Products

A PLD vendor's ability to secure design wins and to maintain or increase market share is highly dependent on the cost and quality of its products, particularly the effectiveness and reliability of its proprietary development software. Development software, working in tandem with device logic architecture and features, creates the functionality desired by the customer. As customers gain familiarity with a particular PLD vendor's software, they often want to use that same software again in another design, giving that PLD vendor a potential advantage as the next system is designed. We develop our software in parallel with our devices, and there are schedule and integration risks between the two processes. If we fail to create adequate software to support our new devices as they are introduced, we weaken our competitive position, which can have long-lasting effects if customers switch to competing solutions and become less familiar and less skilled with our software.

We focus the majority of our research and development resources on next-generation FPGAs because increasing our FPGA market share is important to our long-term growth and profitability. Due to the higher integration density and lower cost per function, the FPGA market has outgrown the CPLD market in recent years, and industry participants and observers believe this trend will continue. Since the initial introduction of our Stratix and Cyclone FPGA families in 2002, we have introduced several more FPGA families in the Stratix, Cyclone and Arria series of products. As a result of these product introductions, we estimate, based on publicly available data and with information derived from Gartner Dataquest, that our market share has increased as follows:


Market Share	2005		2010
PLD	34	%	40	%
FPGA	32	%	39	%
CPLD	37	%	42	%

Complementing our Stratix FPGAs is our HardCopy family of ASICs. The availability of a HardCopy conversion path for high-density FPGA designs is a competitive advantage. We first shipped HardCopy devices in 2001, offering customers low-cost, non-programmable production devices that use our highest density FPGAs as an integrated development vehicle. HardCopy devices are targeted specifically at those applications and customers that have used PLDs for prototyping and development and traditional cell-based ASICs from other vendors for their volume production needs.

We have improved our CPLD offering by introducing the MAX II family in 2004, the MAX IIZ family in 2007, and the MAX V family in 2010. MAX V CPLDs offer pricing and features that we believe are competitively attractive, with cost, performance, power consumption, and density that are superior to our previous offerings.

An FPGA family typically reaches peak sales four to five years after initial product shipment. As a result, the Stratix II and Cyclone II families we introduced in 2004, which comprised approximately 25% of our net sales in 2010, may be at or near peak sales. We believe that the products we introduced from 2006 to 2010 have yet to reach peak sales, but will eventually experience sales declines. To improve or even sustain our growth rate, we must successfully introduce successor generations of devices. The degree to which other PLD vendors improve the competitiveness and execution of their products may impair our ability to improve our growth rate.

Within the next several quarters, we plan to ship newer FPGA families using more advanced production techniques that will further improve product performance and lower cost. Our foundry partner, Taiwan Semiconductor Manufacturing Company (“TSMC”), will manufacture these die using production processes that are new to the industry. Given the extreme complexity of semiconductor fabrication, TSMC may encounter difficulties that could delay our product launch or limit supply so that we would be unable to meet customer commitments. We may discover manufacturing errors after we begin shipping, which would harm customer relations and cause us to incur additional unforeseen costs. Simultaneous introduction of new PLD architectures and ramp of new technology processes are inherently risky. Diagnosing failures, identifying root causes, and implementing corrective actions in a production wafer fabrication facility are expensive and time-consuming. We may not successfully commercialize our new products, or our new products may not enable us to maintain or increase market share. Some of our competitive offerings may be offered later than the competition and it is possible that our competitive offerings will be less effective, thus weakening our market share.

It is also possible that our primary competitor may have secured design wins that, when they enter production, will reverse some of our recent market share gains. Our main competitor is larger in size with more sales, and research and development resources, and we may not enjoy the same success that we saw with previous FPGA generations.

Critical Accounting Estimates

The preparation of our consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires our management to make certain judgments and estimates that affect the amounts reported in our consolidated financial statements. Our management believes that we consistently apply these judgments and estimates and the consolidated financial statements fairly represent all periods presented. However, any differences between these judgments and estimates and actual results could have a material impact on our consolidated statements of income and financial condition. Critical accounting estimates, as defined by the Securities and Exchange Commission (“SEC”), are those that are most important to the portrayal of our financial condition and results of operations and require our management's most difficult and subjective judgments and estimates of matters that are inherently uncertain. Our critical accounting estimates include those regarding (1) revenue recognition; (2) valuation of inventories; and (3) income taxes.

Revenue Recognition

We sell the majority of our products to distributors for subsequent resale to OEMs or their subcontract manufacturers. In most cases, sales to distributors are made under agreements allowing for subsequent price adjustments and returns. We defer recognition of revenue and costs until the products are resold by the distributor. Our revenue reporting is highly dependent on receiving pertinent and accurate data from our distributors in a timely fashion. Distributors provide us with periodic data regarding the product, price, quantity, and end customer when products are resold as well as the quantities of our products they still have in stock. We maintain system controls to validate distributor data and to verify that reported data is accurate. At times, we must use estimates and apply judgments to reconcile distributors' reported inventories to their activities. This reconciliation process requires us to estimate the amount of in-transit shipments (net of in-transit returns) to our distributors. In-transit days can significantly vary among geographies and individual distributors. We also apply judgment when estimating the total value of price concessions earned by our distributors but not claimed by the end of the reporting period. This is because there is a time lag between the price concessions earned and claimed by the distributors for any underlying resale of products. Any error in our judgment could lead to inaccurate reporting of our revenues, deferred income and allowances on sales to distributors, and net income.

Valuation of Inventories

Inventories are recorded at the lower of cost determined on a first-in-first-out basis (approximated by standard cost) or market. We routinely compare our inventory against projected demand and record provisions for excess and obsolete inventories as necessary. We establish provisions for inventory for technological obsolescence or if inventory levels on hand are in excess of projected customer demand. The recording of such provisions results in a write-down of inventory to net realizable value and a charge to cost of goods sold. Historically, it has been difficult to forecast customer demand. Actual demand may materially differ from our projected demand, and this difference could have a material impact on our gross margin and inventory balances based on additional provisions for excess or obsolete inventory or a benefit from inventory previously written down. Many of the orders we receive from our customers and distributors request delivery of product on relatively short notice and with lead times less than our manufacturing cycle time. In order to provide competitive delivery times to our customers, we build and stock a certain amount of inventory in anticipation of customer demand that may not materialize. Moreover, as is common in the semiconductor industry, we generally allow customers to cancel orders with minimal advance notice. Thus, even product built to satisfy specific customer orders may not ultimately be required to fulfill customer demand.

Income Taxes

We record a tax provision for the anticipated tax consequences of the reported results of operations. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, and for operating losses and tax carryforwards. We record valuation allowances, when necessary, to reduce our deferred tax assets to the amount that management estimates is more likely than not to be realized. If, in the future, we determine that we are not likely to realize all or part of our net deferred tax assets, an adjustment to the deferred tax asset valuation allowance would be recorded as a charge to earnings in the period such determination is made.

We measure and recognize uncertain tax positions in accordance with U.S. GAAP, whereby we only recognize the tax benefit from an uncertain tax position if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the merits of the position.

The calculation of our tax liabilities involves the inherent uncertainty associated with the application of U.S. GAAP and complex tax laws. We are subject to examination by various taxing authorities. We believe we have adequately provided in our financial statements for additional taxes that we estimate may be required to be paid as a result of such examinations. If the payment ultimately proves to be unnecessary, the reversal of the tax liabilities would result in tax benefits being recognized in the period we determine the liabilities are no longer necessary. If an ultimate tax assessment exceeds our estimate of tax liabilities, an additional charge to expense will result. See Note 13 - Income Taxes to our consolidated financial statements for additional information.

Results of Operations

On September 23, 2008, our board of directors approved a change in our fiscal year end from the Friday nearest December 31 to December 31 of each year. This change was effective beginning with our fiscal year 2008. As a result of the change in our fiscal year end, our fiscal years ended December 31, 2010 (2010) and December 31, 2009 (2009) each contain 365 days and our fiscal year ended December 31, 2008 (2008) contains 369 days.

Results of operations expressed as a percentage of net sales were as follows:

Sales Overview

Net sales were $1.95 billion in 2010, $1.20 billion in 2009 and $1.37 billion in 2008. Net sales increased by 64% in 2010 from 2009, outpacing the general semiconductor, ASIC, ASSP and PLD markets by a wide margin. Improved end-market conditions and increased PLD content in new generation systems were both contributors to the PLD industry growth. Our market success with 65 nanometer and 40 nanometer FPGAs led to Altera's significant outgrowth of the PLD industry. The significant increase in net sales, primarily due to strong growth in sales of our New Products, was broad-based, covering large and small customer categories and all geographies.

The decrease in Net sales in 2009 from 2008 was due to a general decline in demand associated with the 2009 economic downturn.

Huawei Technologies Co., Ltd. (“Huawei”), an OEM, individually accounted for 13% of net sales in 2010 and 11% in 2009. No other individual OEM accounted for more than 10% of net sales in 2010 or 2009. No single end customer accounted for more than 10% of net sales in 2008. See also Note 4 - Accounts Receivable, Net and Significant Customers to our consolidated financial statements.

Sales by Product Category

We classify our products into three categories: New, Mainstream, and Mature and Other Products. The composition of each product category is as follows:


•	New Products include the Stratix^® III, Stratix IV (including E, GX and GT), Arria^® II GX, Cyclone^® III, Cyclone IV (including E and GX), MAX^® II, HardCopy^® III , and HardCopy IV devices;


•	Mainstream Products include the Stratix II (and GX), Arria GX, Cyclone II, and HardCopy II devices; and


•	Mature and Other Products include the Stratix (and GX), Cyclone, Classic™, MAX 3000A, MAX 7000, MAX 7000A, MAX 7000B, MAX 7000S, MAX 9000, HardCopy, FLEX^® series, APEX™ series, ACEX^® series, Mercury™, and Excalibur™ devices, configuration and other devices, intellectual property cores, and software and other tools.

The product categories above have been constructed to approximate the relative life cycle stages of our products. The product categories' compositions are adjusted approximately every two to three years. During 2010, we adjusted product categories to move certain products from New Products to Mainstream Products and certain products from Mainstream Products to Mature and Other Products. All prior period data has been adjusted to conform to the current classification. New Products are primarily comprised of our most advanced products. Customers typically select these products for their latest generation of electronic systems. Demand is generally driven by prototyping and production needs. Mainstream Products are somewhat older products that are generally no longer design-win vehicles. Demand is driven by customers' later stage production-based needs. Mature Products are yet older products with demand generated by the oldest customer systems still in production. This category also includes sales of software, intellectual property, and other miscellaneous devices.

Net Sales by product category were as follows:


							Annual Growth Rate
	2010		2009		2008		2010		2009

New	43	%	24	%	9	%	196	%	122	%
Mainstream	28	%	33	%	33	%	36	%	(11	)%
Mature and Other	29	%	43	%	58	%	11	%	(35	)%
Net Sales	100	%	100	%	100	%	64	%	(13	)%

Sales by Vertical Market

During 2009, we modified vertical market classifications to more closely align with end customer products and product requirements. In addition, we refined our methodology for assigning net sales to vertical markets to better align distributor price discounts with end customer markets. Accordingly, prior year data has been adjusted to conform to this presentation. The following vertical market data is derived from data that is provided to us by our distributors and end customers. With a broad base of customers, who in some cases manufacture end products spanning multiple market segments, the assignment of net sales to a vertical market requires the use of estimates, judgment, and extrapolation. As such, actual results may differ from those reported.

Net Sales by vertical market were as follows:


							Annual Growth Rate
	2010		2009		2008		2010		2009

Telecom & Wireless	44	%	44	%	36	%	64	%	4	%
Industrial Automation, Military & Automotive	21	%	22	%	24	%	61	%	(18	)%
Networking, Computer & Storage	14	%	14	%	16	%	55	%	(20	)%
Other	21	%	20	%	24	%	73	%	(28	)%
Net Sales	100	%	100	%	100	%	64	%	(13	)%

Sales of FPGAs and CPLDs

Our PLDs consist of field-programmable gate arrays, or FPGAs, and complex programmable logic devices, or CPLDs. FPGAs consist of our Stratix, Cyclone, Arria, APEX, FLEX, and ACEX series, as well as our Excalibur and Mercury families. CPLDs consist of our MAX, MAX II, and Classic families. Our other products consist of HardCopy, HardCopy II and other masked programmed logic devices, configuration devices, software and other tools and IP cores (collectively, “Other Products”).

Net sales of FPGAs and CPLDs, and Other Products were as follows:


							Annual Growth Rate
	2010		2009		2008		2010		2009

FPGA	82	%	77	%	74	%	73	%	(9	)%
CPLD	12	%	15	%	18	%	29	%	(27	)%
Other Products	6	%	8	%	8	%	36	%	(18	)%
Net Sales	100	%	100	%	100	%	64	%	(13	)%

Sales by Geography

The following table is based on the geographic location of the original equipment manufacturers or the distributors who purchased our products. The geographic location of distributors may be different from the geographic location of the ultimate end users.

Net Sales by geography were as follows:


							Annual Growth Rate
	2010		2009		2008		2010		2009

Americas	19	%	20	%	23	%	50	%	(23	)%

Net Sales	100	%	100	%	100	%	64	%	(13	)%

Price Concessions and Product Returns from Distributors

We sell the majority of our products to distributors worldwide at a list price. Our distributors resell our products to end customers at a very broad range of individually negotiated prices based on a variety of factors, including customer, product, quantity, geography and competitive differentiation. Under these circumstances, we remit back to the distributor a portion of its original purchase price after the resale transaction is completed and we validate the distributor's resale information, including end customer, device, quantity and price, against the distributor price concession that we have approved in advance. To receive price concessions, distributors must submit the price concession claims to us for approval within 60 days of the resale of the product to an end customer. Primarily because of the uncertainty related to the final price, we defer revenue recognition on sales to distributors until our products are sold from the distributor to the end customer, which is when our price is fixed or determinable. Accordingly, these pricing uncertainties impact our results of operations, liquidity and capital resources. Total price concessions earned by distributors were $6.0 billion and $3.5 billion for 2010 and 2009, respectively. See Note 8 - Deferred Income and Allowances on Sales to Distributors to our consolidated financial statements. Average aggregate price concessions typically range from 65% to 80% of our list price on an annual basis, depending upon the composition of our sales, volume and factors associated with timing of shipments to distributors or payment of price concessions.

Our distributors have certain rights under our contracts to return defective, overstocked, obsolete and discontinued products. Our stock rotation program generally allows distributors to return unsold product to Altera, subject to certain contract limits, based on a percentage of sales occurring over various periods prior to the stock rotation. Products resold by the distributor to end customers are no longer eligible for return, unless specifically authorized by us. In addition, we generally warrant our products against defects in material, workmanship and non-conformance to our specifications. Returns from distributors totaled $178.4 million and $182.4 million for 2010 and 2009, respectively. See Note 8 - Deferred Income and Allowances on Sales to Distributors to our consolidated financial statements.

Gross Margin


	2010		2009		2008

Gross Margin Percentage	71.0	%	66.8	%	67.1	%

Gross margin rates are heavily influenced by both vertical market mix and the timing of material cost improvements. Our gross margin percentage increased in 2010 by 4.2 points when compared to 2009, primarily as a result of manufacturing cost reductions, specifically due to improved yields on certain of our new products and increased efficiency in our processes. While these variables will continue to fluctuate on a quarterly basis, we continue to target a 65% gross margin over the long term. We believe the 65% gross margin target affords us the right mix of growth opportunities across all served markets.

Gross margin percentages decreased in 2009 by 0.3 points compared to 2008 primarily as a result of a disproportionate decrease in revenue from our smaller, higher margin customer base. We also experienced a more pronounced decline in our highest margin market segments.

Stock-based compensation expense included in Cost of sales did not have a significant impact on our gross margin in 2010, 2009 or 2008.

Research and Development Expense

Research and development expense includes costs for compensation and benefits (including stock-based compensation), development masks, prototype wafers, and depreciation and amortization. These expenditures are for the design of new PLD and ASIC families, the development of process technologies, new package technology, software to support new products and design environments, and IP cores.

We will continue to make significant investments in the development of new products and focus our efforts on the development of new programmable logic devices that use advanced semiconductor wafer fabrication processes, as well as related development software. We are currently investing in the development of future silicon products, as well as our Quartus II software, our library of IP cores, and other future products.


($ in millions)	2010			2009			2008			2010 vs. 2009 Change		2009 vs. 2008 Change

Research and Development Expense	$	264.6		$	260.2		$	257.7		2	%	1	%

Percentage of Net Sales	13.5		%	21.8		%	18.8		%

Research and development expense for 2010 increased by $4.4 million, or 2%, when compared with 2009. The increase was primarily attributable to the following offsetting factors: a $17.2 million increase in variable compensation expense based on higher operating results for 2010, the absence of a gain of $3.6 million from the substantive termination of our retiree medical plan during 2009, a $3.0 million increase in consulting services, and a $19.5 million decrease in spending on masks and wafers due to the timing of product development activities. See Note 15 - Employee Benefit Plans for a detailed discussion of the substantive termination of our retiree medical plan in 2009.

Research and development expense for 2009 increased by $2.5 million, or 1%, when compared with 2008. The increase was primarily attributable to a $21.4 million increase in spending on masks and wafers as a result of tape-outs of various new products in 2009, and a $4.2 million increase in stock-based compensation expense resulting from higher awards in 2009 and a change in estimate of our expected forfeiture rate. These increases were partially offset by a $2.6 million decrease in labor costs due to $6.7 million of cost savings from reduced headcount associated with the restructuring activities in 2009, partially offset by $4.1 million of restructuring charges, a gain of $3.6 million from the substantive termination of our retiree medical plan, a $5.8 million decrease in variable compensation expense based on lower 2009 operating results, a $3.3 million decrease in spending on prototype and package tooling and a combined $6.5 million decrease in rental, travel and consulting expenses. See Note 12 - Stock-Based Compensation to our consolidated financial statements for more information on the change in our expected forfeiture rate, Note 15 - Employee Benefit Plans for a detailed discussion of the substantive termination of our retiree medical plan and Note 17 - Restructuring Charges for further information about our restructuring activities during 2009.

Selling, General, and Administrative Expense

Selling, general, and administrative expense primarily includes compensation and benefits (including stock-based compensation) related to sales, marketing, and administrative employees, commissions and incentives, depreciation, legal, advertising, facilities, and travel expenses.


($ in millions)	2010			2009			2008			2010 vs. 2009 Change		2009 vs. 2008 Change

Selling, General and Administrative Expense	$	254.5		$	234.1		$	255.4		9	%	(8	)%

Percentage of Net Sales	13.0		%	19.6		%	18.7		%

Selling, general, and administrative expense for 2010 increased by $20.4 million, or 9%, when compared with 2009. The increase was primarily attributable to an $8.3 million increase in variable compensation expense based on higher operating results for 2010, the absence of a gain of $2.6 million from the substantive termination of our retiree medical plan during 2009, a $6.0 million increase in commission expenses driven by higher sales volume, and the absence of a benefit of $2.3 million from a change in estimate of our allowance for doubtful accounts during 2009. See Note 4 - Accounts Receivable, Net and Significant Customers to our consolidated financial statements for a detailed discussion of the change in estimate of our allowance for doubtful accounts during 2009, and Note 15 - Employee Benefit Plans for a detailed discussion of the substantive termination of our retiree medical plan in 2009.

Selling, general, and administrative expense for 2009 decreased by $21.3 million, or 8%, when compared with 2008. The decrease was primarily due to a gain of $2.6 million from the substantive termination of our retiree medical plan, a $4.0 million decrease in variable compensation expense based on lower 2009 operating results, a benefit of $2.3 million from a change in estimate of our allowance for doubtful accounts, an $11.1 million decrease in commission expenses due to lower sales for 2009 and a combined $9.3 million decrease in maintenance, travel, advertising, depreciation and legal expenses due to our ongoing efforts to improve operating efficiency. These decreases were partially offset by an $11.1 million increase in stock-based compensation expense resulting from higher awards in 2009 and a change in estimate of our expected forfeiture rate. Labor costs for 2009 were relatively flat compared with 2008. The $5.7 million of restructuring charges incurred in 2009 were offset by the savings in labor costs as a result of the restructuring activities. See Note 4 - Accounts Receivable, Net and Significant Customers to our consolidated financial statements for a detailed discussion of the change in estimate of our allowance for doubtful accounts, Note 12 - Stock-Based Compensation for more information on the change in our expected forfeiture rate, Note 15 - Employee Benefit Plans for a detailed discussion of the substantive termination of our retiree medical plan and Note 17 - Restructuring Charges for further information about our restructuring activities during 2009.

Deferred Compensation Plan

We allow our U.S.-based officers and director-level employees to defer a portion of their compensation under the Altera Corporation Non-Qualified Deferred Compensation Plan (“NQDC Plan”). Since the inception of the NQDC Plan, we have not made any contributions to the NQDC Plan and we have no commitments to do so in the future. There are no NQDC Plan provisions that provide for any guarantees or minimum return on investments. Investment income or loss earned by the NQDC Plan is recorded as (Gain) loss on deferred compensation plan securities in our consolidated statements of income. We reported losses (gains) on NQDC Plan assets of $(6.8) million, $(11.8) million and $18.1 million in 2010, 2009 and 2008, respectively. These amounts resulted from the overall market performance of the underlying securities. The investment loss (gain) also represents a decrease (increase) in the future payout to employees and is recorded as Compensation expense (benefit) - deferred compensation plan in our consolidated statements of income. The compensation expense (benefit) associated with our deferred compensation plan obligations is offset by losses (gains) from related securities. The net effect of the investment income or loss and related compensation expense or benefit has no impact on our income before income taxes, net income, or cash balances. See Note 15 - Employee Benefits Plans to our consolidated financial statements for a detailed discussion of our NQDC Plan.

Interest Income and Other

Interest income and other consists mainly of interest income generated from investments in high-quality fixed income securities. The year-over-year decrease in Interest income and other was primarily due to a decrease in interest income as a result of lower returns on our money market funds, partially offset by the effect of an increase in invested balances.

Interest Expense

The year-over-year decrease in Interest expense was due primarily to the decrease of the LIBOR rate, which represents the principal basis of our interest rate on the outstanding borrowings under our long term credit facility. See Note 16 - Long-term Credit Facility to our consolidated financial statements.

Income Tax Expense

Our effective tax rate reflects the impact of significant amounts of our earnings being taxed in foreign jurisdictions at rates substantially below the U.S. statutory rate. Our effective tax rates were 9.8% for 2010, 17.8% for 2009 and 14.2% for 2008.

The significant net decrease in our effective tax rate in 2010 was primarily due to the following factors. During 2010, we reversed $11.7 million of liabilities that were originally recorded in 2009, for uncertain tax positions, as a result of a court decision issued in March 2010, holding that stock-based compensation was not required to be included in certain transfer pricing arrangements between a U.S. company and its foreign subsidiary. Due to the expiration of the statute of limitations for certain foreign jurisdictions, we reversed $7.7 million of liabilities for uncertain tax positions. In addition, the decrease in our effective tax rate was also due to the impact of proportionately higher earnings in foreign jurisdictions taxed at rates below the U.S. statutory tax rate, partially offset by the increase in the effective tax rate due to the California law change providing the option to elect an alternative method to attribute taxable income to California effective January 1, 2011. As a result, we revalued our state deferred tax assets that are expected to reverse after the effective date of the change and recognized discrete income tax expense charges of $8.2 million during 2010. See Note 13 - Income Taxes to our consolidated financial statements for further information.

Restructuring Charges

During 2009, we announced a net reduction of approximately 120 positions. We incurred restructuring-related charges of approximately $10.0 million in 2009. The charges were comprised of employee severance costs of approximately $7.6 million, charges related to the termination of certain external sales representatives of approximately $2.3 million and operating lease impairments of approximately $0.1 million. As a result of the workforce reduction, our approximate annual net cost savings are $20.0 million.

The restructuring charges for year 2009 are included in our consolidated statements of income as follows:


(In thousands)
Cost of sales	$	137
Research and development expense	4,104
Selling, general, and administrative expense	5,728
	$	9,969

No significant restructuring activities were initiated in 2010 or 2008.

All restructuring obligations were fully settled as of December 31, 2010. See Note 17 - Restructuring Charges to our consolidated financial statements for additional information.

Financial Condition, Liquidity, Credit Facility and Capital Resources

Overview

We derive our liquidity and capital resources primarily from our cash flows from operations. We have a $750 million unsecured revolving credit facility (the “Facility”), which has been used primarily to fund common stock repurchases and to realign our capital structure. As of December 31, 2010, we have borrowed $500 million under the Facility. The remaining capacity of $250 million available under the Facility also represents a source of liquidity. The terms of the Facility require compliance with certain financial and non-financial covenants. Financial covenants require us to maintain certain financial ratios related to interest coverage and financial leverage. As of December 31, 2010, we were in compliance with all such covenants. See Note 16 - Long-term Credit Facility to our consolidated financial statements for further discussion of the Facility.

We use cash from operations and available amounts under the Facility for repurchases of our common stock, cash dividends, and capital expenditures. Based on past performance and current expectations, we believe our current available sources of funds including cash, cash equivalents, and the Facility, plus anticipated cash generated from operations, will be adequate to

finance our operations, stock repurchases, cash dividends and capital expenditures for at least the next year.

Our cash and cash equivalents balance increased by $1.2 billion during the year ended December 31, 2010. The change in cash and cash equivalents for 2010, 2009 and 2008 was as follows:


(In millions)	2010			2009			2008
Net cash provided by operating activities	$	856.7		$	372.7		$	449.3
Net cash (used in) provided by investing activities	(23.0		)	(13.9		)	100.5
Net cash provided by (used in) financing activities	384.8			(28.9		)	(223.1		)
Net increase in cash and cash equivalents	$	1,218.5		$	329.9		$	326.6

Total cash and cash equivalents accounted for 74% and 67% of total assets at December 31, 2010 and 2009, respectively.

Operating Activities

In 2010, our operating activities provided $856.7 million in cash, primarily attributable to net income of $782.9 million, adjusted for non-cash stock-based compensation expense of $67.7 million (net of related tax effects), depreciation and amortization of $27.5 million, and deferred income tax expense of $34.3 million and changes in working capital accounts. Significant changes in working capital accounts (excluding cash and cash equivalents) included a $145.3 million increase in Accounts receivable, net, a $59.2 million increase in Accounts payable and other liabilities, a $146.8 million increase in Deferred income and allowances on sales to distributors, a $76.8 million increase in Inventories, a $52.8 million increase in Other assets and a $15.7 million increase in Income tax payable.

Our sales to distributors are primarily made under agreements allowing for subsequent price adjustments and returns, and we defer recognition of revenue until the products are resold by the distributor. At the time of shipment to distributors, we (1) record a trade receivable at the list selling price since there is a legally enforceable obligation from the distributor to pay us currently for product delivered, (2) relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor, and (3) record deferred revenue and deferred cost of sales in Deferred income and allowances on sales to distributors in the liability section of our condensed consolidated balance sheets. Accordingly, increases in Accounts receivable, net associated with higher billings are generally offset by corresponding increases in Deferred income and allowances on sales to distributors. However, timing differences between gross billings, advances to distributors, discounts earned, collections, revenue recognition and changes in the mix of sales to OEMs and distributors may result in a temporary interruption to the normal relationship between these two accounts.

The $145.3 million increase in Accounts receivable, net, and the $146.8 million increase in Deferred income and allowances on sales to distributors principally related to increased gross billings to distributors and OEMs associated with a significant demand for our products in the fourth quarter of 2010. See Note 8 - Deferred Income and Allowances on Sales to Distributors to our consolidated financial statements.

The $76.8 million increase in Inventories was primarily driven by increased product demand. The $52.8 million increase in Other assets primarily resulted from prepayment of estimated tax and an increase in advances to distributors to help finance their accounts receivable and inventory. The $15.7 million increase in Income tax payable was primarily attributable to higher tax liabilities due to increases in earnings. See Note 13 - Income Taxes to our consolidated financial statements for a detailed discussion.

In 2009, our operating activities provided $372.7 million in cash, primarily attributable to net income of $251.1 million, adjusted for non-cash stock-based compensation expense of $59.8 million (net of related tax effects), depreciation and amortization of $29.0 million, deferred income tax benefit of $5.9 million and a non-cash gain on the substantive termination of our retiree medical plan of $6.5 million. Significant changes in working capital accounts (excluding cash and cash equivalents) included a $136.1 million increase in Accounts receivable, net, a $7.9 million increase in Accounts payable and other liabilities, a $77.6 million increase in Deferred income and allowances on sales to distributors, a $14.9 million decrease in Inventories, a $38.9 million decrease in Other assets and a $39.9 million increase in Income tax payable.

Investing Activities

During 2010, our investing activities primarily consisted of net sales of deferred compensation plan securities of $2.5 million, purchases of property and equipment of $12.4 million and purchase of intangible assets of $5.0 million. In addition, we also made payments related to a business acquisition of $8.0 million. See Note 3 - Acquisition to our consolidated financial

statements.

Cash used for investing activities in 2009 primarily consisted of net purchases of deferred compensation plan securities of $2.1 million and purchases of property and equipment of $11.1 million. We completed construction of a new office building in Penang, Malaysia and incurred total capital expenditures of $28.5 million, which were principally incurred in 2008.

Financing Activities

During 2010, our financing activities primarily consisted of proceeds of $453.7 million from the issuance of common stock to employees through our employee stock plans, partially offset by cash dividend payments of $67.8 million, principal payments on capital lease obligations of $2.9 million, and minimum statutory withholding for vested restricted stock units of $20.2 million.

Cash used for financing activities in 2009 primarily consisted of cash dividend payments of $58.9 million, principal payments on capital lease obligations of $2.4 million and minimum statutory withholding for vested restricted stock units of $10.7 million, partially offset by proceeds of $42.1 million from the issuance of common stock to employees through our employee stock plans.

Our dividend policy could be impacted in the future by, among other items, future changes in our cash flows from operations and our capital spending needs such as those relating to research and development, investments and acquisitions, common stock repurchases, and other strategic investments.

Contractual Obligations

The following table summarizes our significant contractual cash obligations as of December 31, 2010, and the effect that such obligations are expected to have on liquidity and cash flows in future periods:


			Payments Due by Period

(1)	We lease facilities under non-cancelable lease agreements expiring at various times through 2015. Rental expense under all operating leases amounted to $9.0 million, $9.0 million, and $10.2 million in 2010, 2009 and 2008, respectively.


(2)	Due to lengthy subcontractor lead times, we must order materials and services from these subcontractors well in advance, and we are obligated to pay for the materials once they are completed. We expect to receive and pay for these materials in 2011.

(3)

Interest is based on the outstanding credit facility balance and rate in effect as of December 31, 2010. The contractual amounts to be paid are affected by changes in market interest rates. The LIBOR rate used in the calculation of the future interest payments is 0.26% (based on rates in effect as of December 31, 2010). Future changes in market interest rates could materially affect the contractual amounts to be paid.


(4)	We offer to our U.S and non-U.S. employees participation in the Service Award Program (“SAP”). The SAP provides employees with one to four weeks of additional paid vacation upon their attainment of five, ten, fifteen, twenty and twenty-five year service anniversaries. See Note 15 - Employee Benefits Plans to our consolidated financial statements.

Due to the uncertainty with respect to the timing of future cash flows associated with our unrecognized tax benefits as of December 31, 2010, we are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authority. Therefore, $231.8 million of unrecognized tax benefits classified as Income tax payable- non-current in the accompanying consolidated balance sheet as of December 31, 2010, have been excluded from the contractual obligations table

above. See Note 13 - Income Taxes to our consolidated financial statements for a discussion of income taxes.

In addition to the above obligations, in the normal course of business, we enter into a variety of agreements and financial commitments. It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments pursuant to such agreements have not been material. We believe that any future payments required pursuant to such agreements would not be significant to our consolidated financial condition or operating results.

Impact of Foreign Currency and Inflation

We have international operations and incur expenditures in currencies other than U.S. dollars. For non-U.S. subsidiaries and branches, foreign currency transaction gains and losses and the impact of the remeasurement of local currency assets and liabilities into U.S. dollars for 2010, 2009 or 2008 was not significant. During 2008, we entered into forward foreign exchange contracts to reduce our exposure to foreign currency rate changes related to the construction cost for our new building in Penang, Malaysia. As of December 31, 2008 all forward contracts had matured. The realized loss from the settlement of the forward contracts was $1.7 million for 2008. We did not enter into any forward contracts in 2010 or 2009. We do not enter into foreign exchange transactions for trading or speculative purposes.

Common Stock Repurchases

We repurchase shares under our stock purchase program announced on July 15, 1996, which has no specified expiration. No existing repurchase plans or programs have expired, nor have we decided to terminate any repurchase plans or programs prior to expiration. Since the inception of our stock repurchase program through December 31, 2010, our board of directors has authorized 193.0 million shares for repurchase and we have repurchased a total of 178.3 million shares of our common stock for an aggregate cost of $3.7 billion. As of December 31, 2010, 14.7 million shares remained authorized for repurchase under our stock repurchase program.

No shares were repurchased in 2010 or 2009. Common stock repurchase activities for 2008 was as follows:


(In millions, except per share amounts)

Shares repurchased	26.6
Cost of shares repurchased	$	473.229
Average price per share	$	17.78

During 2008, we entered into agreements pursuant to SEC Rule 10b5-1 under which we authorized third-party brokers to purchase shares on our behalf during our normal blackout period according to predetermined trading instructions. In addition, we repurchased shares of our common stock under the guidelines of SEC Rule 10b-18.

Off-balance Sheet Arrangements

As of December 31, 2010, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Subsequent Events

On January 24, 2011, our board of directors declared a cash dividend of $0.06 per common share payable on March 1, 2011 to stockholders of record on February 10, 2011.

New Accounting Pronouncements

Accounting Standards Adopted in 2010

Fair Value Measurements and Disclosures

In January 2010, the Financial Accounting Standards Board (“FASB”) issued amended guidance on fair value measurements and disclosures. The new guidance requires additional disclosures regarding fair value measurements, amends disclosures about

post-retirement benefit plan assets, and provides clarification regarding the level of disaggregation of fair value disclosures by investment class. This guidance is effective for interim and annual reporting periods beginning after December 15, 2009, except for certain Level 3 activity disclosure requirements that will be effective for reporting periods beginning after December 15, 2010. Accordingly, we adopted this amendment in the quarter ended April 2, 2010, except for the additional Level 3 requirements that will be adopted in 2011. See Note 18 — Fair Value of Financial Instruments to our consolidated financial statements.

Subsequent Events

In February 2010, the FASB issued amended guidance on subsequent events. Under this amended guidance, SEC filers are no longer required to disclose the date through which subsequent events have been evaluated in originally issued and revised financial statements. This guidance was effective immediately and we adopted this new guidance in the quarter ended April 2, 2010. See Note 19 — Subsequent Event to our consolidated financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Interest Rate Risk

While we are exposed to interest rate fluctuations in many of the world's leading industrialized countries, our interest income and expense is most sensitive to fluctuations in the general level of U.S. interest rates. Our investment strategy is focused on preservation of capital and supporting our liquidity requirements. Our exposure to market risk as a result of changes in interest rates relates primarily to our cash and cash equivalents, certain interest-rate sensitive assets held under the NQDC Plan and our long-term credit facility. Our NQDC Plan assets include holdings of various issuers, types and maturity dates.

The market value of these investments on any given day during the investment term may vary as a result of market interest rate fluctuations. A hypothetical 10% movement in interest rates during the investment term would not likely have a material impact on the fair value of the portfolio. The actual impact on the fair value of the portfolio in the future may differ materially from this analysis, depending on actual balances and changes in the timing and the amount of interest rate movements.

Our consolidated operating results are affected by, among other factors, interest income on our cash equivalents. If the interest rate declines, our consolidated operating results may be negatively impacted.

In addition to our cash flows from operations, we derive our liquidity from our long-term credit facility (the “Facility”). Our total borrowings under the Facility as of December 31, 2010 were $500 million. Borrowings under this Facility bear a variable interest rate at either a Eurodollar rate (“LIBOR”) or a Prime rate, at our option, plus an applicable margin based upon certain financial ratios, determined and payable quarterly. The interest rate as of December 31, 2010 was LIBOR plus 0.35%. In addition, we pay a facility fee on the entire Facility. This facility fee varies with certain financial ratios and was 0.10% as of December 31, 2010.

Our consolidated operating results and cash flows are exposed to changes in interest rates that could adversely affect the amount of interest expense incurred and paid on the Facility in any given period. Due to the variable interest rate on the Facility, the fair value of the Facility would not likely be materially affected by any future changes in interest rates.

Equity Price Risk

We are exposed to equity price risk inherent in the marketable equity securities held in our NQDC Plan. A hypothetical 10% adverse change in the stock prices of these equity securities would not result in a material impact on our consolidated financial position, operating results or cash flows.

Foreign Currency Risk

We have international operations and incur expenditures in currencies other than U.S. dollars. To date, our exposure to exchange rate volatility, resulting from foreign currency transaction gains and losses and remeasurement of local currency assets and liabilities into U.S. dollars, has been insignificant. If foreign currency rates were to fluctuate by 10% from rates in effect at December 31, 2010, the resulting transaction gains or losses and the effects of remeasurement would not materially affect our consolidated financial position, operating results or cash flows.

ALTERA CORPORATION

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Note 1: The Company

Altera Corporation was founded in 1983 and reincorporated in the State of Delaware in 1997. We design, manufacture, and market high-performance, high-density programmable logic devices, or PLDs, HardCopy ASIC devices, pre-defined design building blocks known as intellectual property (“IP”), cores, and associated development tools. Our PLDs, which consist of field-programmable gate arrays, or FPGAs, and complex programmable logic devices, or CPLDs, are semiconductor integrated circuits that are manufactured as standard chips that our customers program to perform desired logic functions within their electronic systems. With our HardCopy devices we offer our customers a migration path from a PLD to a low-cost, high-volume, non-programmable implementation of their designs. Our customers can license IP cores from us for implementation of standard functions in their PLD designs. Customers develop, compile, and verify their PLD designs, and then program their designs into our PLDs using our proprietary development software, which operates on personal computers and engineering workstations. Our products serve a wide range of customers within the Telecom and Wireless, Industrial Automation, Military and Automotive, Networking, Computer and Storage and Other vertical markets.

Note 2: Significant Accounting Policies

BASIS OF PRESENTATION | On September 23, 2008, our board of directors approved a change in our fiscal year end from the Friday nearest December 31 to December 31 of each year. This change was effective beginning with our fiscal year 2008. As a result of the change in our fiscal year end, our fiscal years ended December 31, 2010 (2010) and December 31, 2009 (2009) each contain 365 days and our fiscal year ended December 31, 2008 (2008) contains 369 days. The consolidated financial statements include our accounts as well as those of our wholly-owned subsidiaries after elimination of all significant inter-company balances and transactions.

USE OF ESTIMATES | The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

CASH EQUIVALENTS | Cash equivalents consist of highly liquid investments with a maturity of three months or less from the date of original purchase. As of December 31, 2010 and 2009, our cash equivalents consisted of money market funds.

DEFERRED COMPENSATION PLAN - MARKETABLE SECURITIES | We allow our U.S.-based officers and director-level employees to defer a portion of their compensation under the Altera Corporation Non-Qualified Deferred Compensation Plan (“NQDC Plan”). The investments held in the NQDC Plan consist of publicly traded equity securities, mutual funds and fixed income securities. We account for these investments as trading securities with gains or losses reported as (Gain) loss on deferred compensation plan securities in our consolidated statements of income.

DEFERRED COMPENSATION PLAN - RESTRICTED CASH EQUIVALENTS | As of December 31, 2010 and 2009, the cash equivalents held in the NQDC Plan consisted of money market funds and were classified as restricted cash equivalents due to legal restrictions associated with the trust held under the Plan.

INVENTORIES | Inventories are recorded at the lower of actual cost (approximated by standard cost) determined on a first-in-first-out basis or market. We establish provisions for inventory if it is in excess of projected customer demand, and the creation of such provisions results in a write-down of inventory to net realizable value and a charge to cost of goods sold.

PROPERTY AND EQUIPMENT | Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method. Estimated useful lives of three to seven years are used for equipment and office furniture, up to forty years for buildings and sixty years for land rights. Leasehold improvements and assets recorded under capital leases are amortized over the shorter of the remaining lease term or the estimated useful life of the asset. Property and equipment also includes costs related to the development of internal use software.

BUSINESS COMBINATIONS AND INTANGIBLE ASSETS | Amounts paid for acquisitions are allocated to the tangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. We then allocate the purchase price in excess of net tangible assets acquired to identifiable intangible assets. The fair value of identifiable intangible assets is based on detailed valuations that use information and assumptions provided by management. We allocate any excess purchase price over the fair value of the net tangible and intangible assets acquired to goodwill. Identifiable intangible assets with finite lives are amortized over their useful lives. Acquisition-related costs, including advisory, legal, accounting, valuation

and other costs, are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in the consolidated financial statements from the acquisition date. We evaluate the remaining useful life of intangible assets on a periodic basis to determine whether events and circumstances warrant a revision to the remaining useful life. If the estimate of an intangible asset’s remaining useful life is changed, we amortize the remaining carrying value of the intangible asset prospectively over the revised remaining useful life.

LONG-LIVED ASSET IMPAIRMENT | We perform reviews of long-lived assets to determine if facts and circumstances indicate that the useful life is shorter than we had originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, we assess the recoverability of the long-lived assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets. If the useful life is shorter than originally estimated, we accelerate the rate of amortization and amortize the remaining carrying value over the new shorter useful life.

FAIR VALUE OF FINANCIAL INSTRUMENTS | We define fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. This is sometimes referred to as an "exit price". As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability, also taking into consideration the principal or most advantageous market in which market participants would transact and the market based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk and credit risk. We apply the following fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1 - Observable inputs such as quoted prices in active markets

Level 2 - Inputs other than the quoted prices in active markets that are observable either directly or indirectly

Level 3 - Unobservable inputs in which there is little or no market data, which require us to develop our own assumptions

This hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, we measure certain financial assets and liabilities at fair value, which consist of our cash equivalents and marketable securities.

Our cash equivalents and investment securities are classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The types of instruments valued based on quoted market prices in active markets include money market securities, exchange traded stocks and open-end mutual funds. Such instruments are generally classified within Level 1 of the fair value hierarchy.

The types of instruments valued based on other observable inputs include bank commercial deposits, corporate commercial paper and municipal obligations. Such instruments are generally classified within Level 2 of the fair value hierarchy.

For certain of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities, the carrying value approximates fair value due to their short maturities. For our long-term credit facility, the carrying value approximates fair value due to its variable interest rate with low margins. The fair value of our long-term credit takes into consideration variables such as credit-rating changes and non-performance risk.

See Note 18 — Fair Value of Financial Instruments to our consolidated financial statements.

CONCENTRATIONS OF CREDIT RISK AND KEY SUPPLIERS | Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash, cash equivalents, and accounts receivable.

We place our cash and cash equivalents in a variety of financial instruments and, by policy, limit the amount of credit exposure through diversification and by restricting our investments to highly rated investment-grade securities.

We sell our products to distributors and original equipment manufacturers (“OEMs”) throughout the world. We attempt to mitigate the concentration of credit risk in our trade receivables through a credit evaluation process, collection terms and by having distributor sales to diverse end customers. Net sales are the sum of our own direct sales to OEMs plus our distributors' resale of Altera products. We rely heavily on two distributors and one OEM to generate a significant portion of our sales.

We depend almost entirely upon Taiwan Semiconductor Manufacturing Company (“TSMC”) to manufacture our silicon wafers. We also depend on TSMC to improve process technologies in a timely manner and to enhance our product designs and cost structure. We have no formalized long-term commitment from TSMC. If market demand for silicon wafers suddenly exceeds market supply, our supply of silicon wafers can become limited quickly. A shortage in foundry manufacturing capacity could hinder our ability to meet demand for our products. Moreover, silicon wafers constitute more than half of our product cost. If we are unable to procure wafers at favorable prices, our gross margins will be adversely affected.

Independent subcontractors, located primarily in Asia, assemble and test our semiconductor products. Because we rely on independent subcontractors to perform these services, we cannot directly control our product delivery schedules or quality levels. Our future success also depends on the financial viability of our independent subcontractors. If the capital structures of our independent subcontractors weaken, we may experience product shortages, quality assurance problems, increased manufacturing costs, and/or supply chain disruption.

The economic, market, social, and political situations in countries where certain independent subcontractors are located are unpredictable, can be volatile, and can have a significant impact on our business because we may not be able to obtain product in a timely manner. Market and political conditions, including manufacturing capacity constraints, currency fluctuation, terrorism, political strife, war, labor disruption, and other factors, including natural or man-made disasters, adverse changes in tax laws, tariff, import or export quotas, power and water shortages, or interruption in air transportation in areas where our independent subcontractors are located also could have a severe negative impact on our operating capabilities.

ADVANCES TO DISTRIBUTORS | On sales to distributors, our payment terms frequently require the distributor to remit payment to us for an amount in excess of their ultimate cost. Our sales price to the distributor may be higher than the amount that the distributor will ultimately owe us because distributors often negotiate price discounts after purchasing the product from us and such discounts are often significant. Under these circumstances, we remit back to the distributor a portion of its original purchase price after the resale transaction is completed and we validate the distributor's resale information, including end customer, device, quantity and price, against the distributor price concession that we have approved in advance. It is our practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current basis, generally within 30 days, for amounts originally invoiced. This practice has an adverse impact on the working capital of our distributors. As such, we have entered into agreements with certain distributors whereby we advance cash to the distributors to reduce the distributor's working capital requirements. These advances are settled in cash at least on a quarterly basis and are estimated based on the amount of ending inventory as reported by the distributor multiplied by a negotiated percentage. Such advances have no impact on revenue recognition or our consolidated statements of income and are a component of Deferred income and allowances on sales to distributors on our consolidated balance sheets. We continuously process discounts taken by distributors against our Deferred income and allowances on sales to distributors. We adjust the recorded amount of the distributor advances based on cash settlements at the end of each quarter. These advances are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand. The agreements governing these advances can be cancelled by us at any time.

We also enter into arrangements that in substance, finance distributors' accounts receivable and inventory. The amounts advanced are classified as Other current assets in our consolidated balance sheets and totaled $66.3 million as of December 31, 2010 and $33.0 million as of December 31, 2009. These arrangements are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand. See Note 8 - Deferred Income and Allowances on Sales to Distributors.

REVENUE RECOGNITION | We sell our products to original equipment manufacturers, or OEMs, and to electronic components distributors who resell these products to OEMs, or their subcontract manufacturers. We sell the majority of our products to distributors for subsequent resale to OEMs or their subcontract manufacturers. In most cases, sales to distributors are made under agreements allowing for subsequent price adjustments and returns, and we defer recognition of revenue until the products are resold by the distributor, at which time our final net sales price is fixed. At the time of shipment to distributors, we (1) record a trade receivable at the list selling price since there is a legally enforceable obligation from the distributor to pay us currently for product delivered, (2) relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor, and (3) record deferred revenue and deferred cost of sales in Deferred income and allowances on sales to distributors in the liability section of our consolidated balance sheets.

Deferred income effectively represents the gross margin on the sale to the distributor; however, the amount of gross margin we recognize in future periods will be less than the originally recorded deferred income as a result of negotiated price concessions. We sell the majority of our products to distributors worldwide at a list price. However, distributors resell our products to end customers at a very broad range of individually negotiated price points based on a variety of factors, including customer,

product, quantity, geography and competitive differentiation. The majority of our distributors' resales are priced at a discount from list price. Under these circumstances, we remit back to the distributor a portion of its original purchase price after the resale transaction is completed and we validate the distributor's resale information, including end customer, device, quantity and price, against the distributor price concession that we have approved in advance. To receive price concessions, distributors must submit the price concession claims to Altera for approval within 60 days of the resale of the product to an end customer. Primarily because of the uncertainty related to the final price, we defer revenue recognition on sales to distributors until our products are sold by the distributor to the end customer, which is when our price is fixed or determinable. A substantial portion of Deferred income and allowances on sales to distributors balance represents a portion of distributors' original purchase price that will be remitted back to the distributor in the future. The wide range and variability of negotiated price concessions granted to distributors does not allow us to accurately estimate the portion of the balance in Deferred income and allowances on sales to distributors that will be remitted back to the distributors. Therefore, we do not reduce deferred income or accounts receivable by anticipated future price concessions; instead, price concessions are typically recorded against Deferred income and allowances on sales to distributors when incurred, which is generally at the time the distributor sells the product to an end customer.

Our distributors have certain rights under our contracts to return defective, overstocked, obsolete and discontinued products. Our stock rotation program generally allows distributors to return unsold product to Altera, subject to certain contract limits based on a percentage of sales occurring over various periods prior to the stock rotation. Products resold by the distributor to end customers are no longer eligible for return. In addition, we generally warrant our products against defects in material, workmanship and material non-conformance to our specifications.

Revenue from products sold directly to OEMs is recognized upon shipment provided that persuasive evidence of an arrangement exists, the price is fixed, title has transferred, collection of resulting receivables is reasonably assured, there are no customer acceptance requirements, and there are no remaining significant obligations. We present any taxes assessed by a governmental authority that are both imposed on and concurrent with our sales on a net basis, excluded from revenues. We record reserves for OEM sales returns and allowances, as a component of Accounts receivable, net, in the accompanying consolidated balance sheets.

IMPAIRMENT OF DEFERRED COST OF SALES | Our deferred cost of sales represents the products shipped from Altera to our distributors. We evaluate whether our deferred cost of sales has been impaired based on expected net cash flows to be received for the deferred item. In assessing the impairment of our deferred cost of sales, we use the FASB guidance, which establishes the lower-of-cost-or-market rule as the guiding principle to be used in assessing whether cost or a lower estimate of realizable value should be used for inventories. We apply our inventory valuation procedures, including potential impairment due to excess or obsolescence, to Altera owned inventory and distributor owned inventory. Realization of the deferred cost occurs because we earn revenue in excess of the amount of costs deferred.

DERIVATIVE FINANCIAL INSTRUMENTS | We account for derivative instruments and hedging activities as either assets or liabilities in the statement of financial position and carry them at fair value. Derivatives that are not designated as hedges for accounting purposes are adjusted to fair value through earnings. We do not enter into foreign exchange transactions for trading or speculative purposes.

During 2008, we entered into forward foreign exchange contracts reducing our exposure to foreign currency rate changes related to the construction cost for our new facility in Penang, Malaysia. These contracts were effective as hedges from an economic perspective, but were not designated as hedges for accounting purposes.

As of December 31, 2008, all the forward foreign exchange contracts had matured. The realized loss from the settlement of the forward contracts of $1.7 million for 2008 is presented in Interest income and other in our 2008 consolidated statements of income. We did not enter into any forward contracts in 2010 or 2009.

INDEMNIFICATION AND PRODUCT WARRANTY | We indemnify certain customers, distributors, suppliers, and subcontractors for attorneys' fees and damages and costs awarded against these parties in certain circumstances in which our products are alleged to infringe third party intellectual property rights, including patents, trade secret, trademarks, or copyrights. We cannot estimate the amount of potential future payments, if any, that we might be required to make as a result of these agreements. To date, we have not paid any claim or been required to defend any action related to our indemnification obligations, and accordingly, we have not accrued any amounts for such indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations.

We generally warrant our devices for one year, against defects in materials, workmanship and material non-conformance to our specifications. We accrue for known warranty issues if a loss is probable and can be reasonably estimated, and accrue for

estimated but unidentified issues based on historical activity. If there is a material increase in customer claims compared with our historical experience or if the costs of servicing warranty claims are greater than expected, we may record a charge against cost of sales. Warranty expense was not significant for any period presented in our consolidated statements of income.

INCOME TAXES | Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been reflected in the financial statements. Deferred tax assets and liabilities are determined based on the differences between the book and tax bases of assets and liabilities and operating loss carryforwards, using tax rates expected to be in effect for the years in which the differences are expected to reverse. A valuation allowance is provided to reduce net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company determines whether it is more likely than not that a tax position will be sustained upon examination. The tax benefit of any tax position that meets the more-likely-than-not recognition threshold is calculated as the largest amount that is more than 50% likely of being realized upon resolution of the uncertainty. To the extent a full benefit is not expected to be realized on the uncertain tax position, an income tax liability is established. Interest and penalties on income tax obligations, including uncertain tax positions, are included in income tax expense.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in a multitude of jurisdictions across our global operations. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from current estimates of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities may result in income tax benefits being recognized in the period when it is determined that the liabilities are no longer necessary. A significant portion of these potential tax liabilities are recorded in non-current income taxes payable on the balance sheets as payment is not expected within one year.

STOCK-BASED COMPENSATION PLANS | We recognize compensation expense for all stock-based awards based on the grant-date estimated fair values, net of an estimated forfeiture rate. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods in our consolidated statements of income.

We use the Black-Scholes option pricing model to determine the estimated fair value for stock-based awards. Stock-based compensation cost for restricted stock units is measured based on the closing fair market value of our common stock on the date of the grant.

FOREIGN CURRENCY REMEASUREMENT | The U.S. dollar is the functional currency for all of our foreign subsidiaries. The monetary assets and liabilities that are not denominated in the functional currency are remeasured into U.S. dollars at the exchange rate in effect at the balance sheet date. Revenue, expenses, gains or losses are remeasured at the average exchange rate for the period. Non-monetary assets and liabilities are remeasured at historical exchange rates. The resultant remeasurement gains or losses are included in Interest income and other in the consolidated statements of income. Such gains or losses are insignificant for all periods presented.

RESEARCH AND DEVELOPMENT EXPENSE | Research and development expense includes costs for compensation and benefits (including stock-based compensation), development masks, prototype wafers, and depreciation and amortization. Research and development costs are charged to expense as incurred.

ADVERTISING EXPENSES | We expense advertising costs as incurred. Advertising expenses were $6.0 million, $5.0 million, and $7.1 million in 2010, 2009 and 2008, respectively.

INCOME PER SHARE | We compute basic income per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. To determine diluted share count, we apply the treasury stock method to determine the dilutive effect of outstanding stock option shares, restricted stock units, and employee stock purchase plan (“ESPP”) shares. Our application of the treasury stock method includes as assumed proceeds the average unamortized stock-based compensation expense for the period and the impact of the pro forma deferred tax benefit or cost associated with stock-based compensation expense.

NEW ACCOUNTING PRONOUNCEMENTS

Accounting Standards Adopted in 2010

Fair Value Measurements and Disclosures

In January 2010, the FASB issued amended guidance on fair value measurements and disclosures. The new guidance requires

additional disclosures regarding fair value measurements, amends disclosures about post-retirement benefit plan assets, and provides clarification regarding the level of disaggregation of fair value disclosures by investment class. This guidance was effective for interim and annual reporting periods beginning after December 15, 2009, except for certain Level 3 activity disclosure requirements that will be effective for reporting periods beginning after December 15, 2010. Accordingly, we adopted this amendment in the quarter ended April 2, 2010, except for the additional Level 3 requirements that will be adopted in 2011. See Note 18 — Fair Value of Financial Instruments to our consolidated financial statements.

Subsequent Events

Note 3: Acquisition

In December 2010, we acquired all of the outstanding equity of Avalon Microelectronics, Inc. ("Avalon"), a leading provider of FPGA based Optical Transport Network solutions, for cash consideration of $8.0 million, net of acquired cash. This acquisition supports our strategy to increase resources and funding to develop, license, and deliver more IP cores, frameworks, and reference designs to our targeted markets. In connection with the acquisition, we are required to pay future installments of $7.5 million to Avalon's former shareholder, contingent upon the continued employment of this individual by Altera. This amount will be recognized as compensation expense in our consolidated statements of income over the four-year service period required by this arrangement.

The following amounts represent the preliminary determination of the fair value of the identifiable assets acquired and liabilities assumed:


(In thousands)	Amount			Amortization life (in years)
Current assets	$	2,069
Fixed and other long-term assets, net	729
Intangible assets:
Completed technology	5,670			6 to 10
Customer relationships	910			5 to 6
Backlog	730			1
Total assets acquired	10,108
Total liabilities assumed	(1,937		)
Net assets acquired	$	8,171

At the acquisition date, the fair value of the tangible assets acquired and the liabilities assumed approximated fair value. As of December 31, 2010, we had not yet finalized the valuation of certain deferred tax items, the impact of which is not expected to have a material effect on our consolidated statements of financial positions or results of operations.

Note 4: Accounts Receivable, Net and Significant Customers

Account receivable, net as of December 31, 2010 and 2009 was comprised of the following:


(In thousands)	December 31, 2010			December 31, 2009

Gross accounts receivable	$	364,114		$	218,647
Allowance for doubtful accounts	(500		)	(500		)
Allowance for sales returns	—			(3		)
Accounts receivable, net	$	363,614		$	218,144

We determine the allowance requirement, on an account by account basis, by calculating an estimated financial risk for each OEM customer or distributor and taking into account other available information that indicates that receivable balances may not be fully collectible. Account balances are charged off against the allowance when it is probable that the receivable will not be recovered.

We sell our products to original equipment manufacturers, or OEMs, and to electronic components distributors who resell these products to OEMs, or their subcontract manufacturers. Net sales by customer type and net sales to significant customers were as follows:


(Percentage of Net Sales)	2010		2009		2008

Sales to distributors	81	%	82	%	91	%
Sales to OEMs	19	%	18	%	9	%
	100	%	100	%	100	%

Significant Distributors⁽¹⁾:
Arrow Electronics, Inc. ( “Arrow”)	46	%	45	%	46	%
Macnica, Inc. (“Macnica”)	20	%	15	%	14	%


(1)	Except as presented above, no other distributor accounted for greater than 10% of our net sales for 2010, 2009 or 2008.

Huawei Technologies Co., Ltd., an OEM, individually accounted for 13% of our net sales in 2010 and 11% in 2009. No other individual OEM accounted for more than 10% of our net sales for 2010 or 2009. No individual OEM accounted for more than 10% of our net sales in 2008.

As of December 31, 2010, accounts receivable from Arrow, Macnica and Avnet, Inc. including its affiliates (“Avnet”) individually accounted for approximately 18%, 51% and 12%, respectively, of our total accounts receivable. As of December 31, 2009, accounts receivable from Arrow, Macnica and Avnet individually accounted for approximately 36%, 21% and 14%, respectively, of our total accounts receivable. No other distributor or OEM accounted for more than 10% of our accounts receivable as of December 31, 2010 or 2009.

Note 5: Marketable Securities

CASH EQUIVALENTS | Cash equivalents as of December 31, 2010 and 2009 consisted mainly of $2.7 billion and $1.5 billion of money market funds, respectively.

For money market funds, the cost basis equals fair value and, accordingly, there are no unrealized gains or losses. Investment income from these securities was $4.3 million, $6.2 million and $31.7 million in 2010, 2009 and 2008, respectively, and is presented in Interest income and other in our consolidated statements of income.

DEFERRED COMPENSATION PLAN ASSETS | Assets held in the trust associated with the NQDC Plan consist of money market shares, publicly traded equity securities, mutual funds and fixed income securities. Except for the money market shares, we account for these assets as trading securities, with gains or losses reported as (Gain) loss on deferred compensation plan securities in our consolidated statements of income. (Gain) loss from these assets is offset by the compensation expense (benefit) associated with our deferred compensation plan obligations. Therefore, gains or losses associated with the NQDC Plan

assets do not impact our income before income taxes, net income, or cash balances.

Investment income (loss) from our NQDC plan assets for 2010, 2009 and 2008 was comprised of the following:


(In thousands)	2010			2009			2008

Depreciation expense includes the amortization of assets recorded under capital leases. Depreciation expense was $26.7 million in 2010, $28.8 million in 2009, and $29.7 million in 2008. Depreciation and amortization expense as presented in our consolidated statements of cash flows includes the above amounts, together with amortization expense on our intangible assets. Intangible asset amortization expense was not significant for any period presented in our consolidated income statements.

Assets held under capital leases, included in Equipment and software as presented above, totaled $5.0 million (net of accumulated amortization of $11.3 million) as of December 31, 2010 and $8.6 million (net of accumulated amortization of $6.9 million) as of December 31, 2009. The amortization expense recognized on assets held under capital leases was $4.4 million, $4.4 million and $4.2 million for 2010, 2009 and 2008, respectively.

Note 9: Commitments and Contingencies

OPERATING LEASE COMMITMENTS | We lease facilities and equipment under non-cancelable lease agreements expiring at various times, as presented below. The facility leases generally require us to pay property taxes, insurance, maintenance, and repair costs. Total rental expense under all operating leases was $9.0 million, $9.0 million, and $10.2 million in 2010, 2009 and 2008, respectively. We have the option to extend or renew most of our leases which may increase the future minimum lease commitments. Future minimum lease payments under all non-cancelable operating lease obligations as of December 31, 2010 are as follows:


Year	Operating
	(In thousands)
2011	$	7,619
2012	5,045
2013	3,932
2014	2,744
2015	1,256
2016 and thereafter	677
Total	$	21,273

PURCHASE OBLIGATIONS | We depend entirely upon subcontractors to manufacture our silicon wafers and provide assembly and test services. Due to lengthy subcontractor lead times, we must order these materials and services from these subcontractors well in advance, and we are obligated to pay for the materials and services once they are completed. As of December 31, 2010, we had approximately $185.5 million of outstanding purchase commitments to such subcontractors. We

expect to receive and pay for these materials and services over the next six months.

OTHER COMMITMENTS | In addition to operating leases obligations, we enter into a variety of agreements and financial commitments in the normal course of business. It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments pursuant to such agreements have not been material. We believe that any future payments required pursuant to such agreements would not be material to our financial condition or results of operations.

LEGAL PROCEEDINGS | We are named as a party to a lawsuit concerning our historical stock option practices and related accounting and reporting.

Note 10: Income per Share

A reconciliation of basic and diluted income per share is presented below:


(In thousands, except per share amounts)	2010		2009		2008

Basic:

Net income	$	782,884	$	251,062	$	359,651
Basic weighted shares outstanding	307,302		294,493		300,951
Net income per share	$	2.55	$	0.85	$	1.20

Diluted:

Net income	$	782,884	$	251,062	$	359,651

Weighted shares outstanding	307,302		294,493		300,951
Effect of dilutive securities:
Stock options, ESPP shares, and restricted stock unit shares	6,610		2,687		3,653

Diluted weighted shares outstanding	313,912		297,180		304,604

Net income per share	$	2.49	$	0.84	$	1.18

In applying the treasury stock method, we excluded 3.5 million stock option shares for 2010 because their effect was anti-dilutive. Anti-dilutive stock option shares totaled 27.7 million for 2009 and 26.7 million for 2008. While these stock option shares are currently anti-dilutive, they could be dilutive in the future. All restricted stock units outstanding as of December 31, 2010, December 31, 2009 and December 31, 2008 were included in our treasury stock method calculation.

Note 11: Stockholders' Equity

COMMON STOCK REPURCHASES | We repurchase shares under our stock purchase program announced on July 15, 1996, which has no specified expiration. No existing repurchase plans or programs have expired, nor have we decided to terminate any repurchase plans or programs prior to expiration. Since the inception of our stock repurchase program through December 31, 2010, our board of directors has authorized 193.0 million shares for repurchase and we have repurchased a total of 178.3 million shares of our common stock for an aggregate cost of $3.7 billion. All shares were retired upon acquisition and have been recorded as a reduction of Common stock, Capital in excess of par value and Retained earnings, as applicable. As of December 31, 2010, 14.7 million shares remained authorized for repurchase under our stock repurchase program.

No shares were repurchased in 2010 or 2009. Common stock repurchase activities for 2008 was as follows:


(In millions, except per share amounts)

Shares repurchased	26.6
Cost of shares repurchased	$	473.2
Average price per share	$	17.78

Note 12: Stock-Based Compensation

Our stock-based compensation plans include the 2005 Equity Incentive Plan (the “2005 Plan”) and the 1987 Employee Stock Purchase Plan (“ESPP”).

2005 EQUITY INCENTIVE PLAN | Our equity incentive program is a broad-based, long-term retention program intended to attract, motivate, and retain talented employees as well as align stockholder and employee interests. The 2005 Plan provides

stock-based incentive compensation (“awards”) to both our eligible employees and non-employee directors. Awards that may be granted under the 2005 Plan include non-qualified and incentive stock options, restricted stock units (“RSU”s), performance-based restricted stock units (“PRSU”s), restricted stock awards, stock appreciation rights, and stock bonus awards. To date, awards granted under the 2005 Plan consist of stock options, RSUs and PRSUs. The majority of stock-based awards granted under the 2005 Plan vest over 4 years. Stock options granted under the 2005 Plan have a maximum contractual term of 10 years. On May 6, 2010, our stockholders approved an amendment to the 2005 Plan to increase the shares reserved for future issuance by 5 million. As of December 31, 2010, the 2005 Plan had a total of 26.8 million shares reserved for future issuance, of which 17.1 million shares were available for future grants.

In 2007, we initiated the PRSU program for selected members of our senior management. The PRSUs vest upon: (1) Altera achieving net income (including equity compensation expense) from continuing operations as a percentage of net sales above a certain percentage; and (2) the grantees satisfying certain service requirements. For 2010, 2009 and 2008, 0.3 million, 0.6 million and 0.3 million PRSUs were granted, respectively.

Historically, we used equity awards in the form of stock options as one of the means for recruiting and retaining highly skilled talent. We now issue primarily RSUs and PRSUs rather than stock options for eligible employees as the primary type of long-term equity based award.

A summary of activity for our RSUs and PRSUs for 2010 and information regarding RSUs and PRSUs outstanding and expected to vest as of December 31, 2010 is as follows:


(In thousands, except per share amounts and terms)	Number of Shares		Weighted-Average Grant-Date Fair Market Value Per Share		Weighted-Average Remaining Contractual Term (in Years)	Aggregate Intrinsic Value⁽¹⁾

(1)	Aggregate intrinsic value represents the closing price per share of our stock on December 31, 2010, multiplied by the number of RSUs and PRSUs outstanding or vested and expected to vest as of December 31, 2010.

The total fair value of RSUs and PRSUs vested and expensed during 2010, 2009 and 2008 was $53.4 million, $50.0 million and $29.0 million, respectively.

A summary of stock option activity for 2010 and information regarding stock options outstanding, exercisable, and vested and expected to vest as of December 31, 2010 is as follows:


(In thousands, except per share amounts and terms)	Number of Shares		Weighted-Average Exercise Price Per Share		Weighted-Average Remaining Contractual Term (in Years)	Aggregate Intrinsic Value⁽¹⁾

(1)	For those stock options with an exercise price below the closing price per share on December 31, 2010, aggregate

intrinsic value represents the difference between the exercise price and the closing price per share of our common stock on December 31, 2010, multiplied by the number of stock options outstanding, exercisable, or vested and expected to vest as of December 31, 2010.

For 2010, 2009 and 2008, 20.0 million, 1.5 million and 3.3 million non-qualified stock option shares were exercised, respectively. The total intrinsic value of stock options exercised for 2010, 2009 and 2008 was $139.6 million, $6.2 million and $22.6 million respectively. The aggregate intrinsic value represents the difference between the exercise price and the selling price received by option holders upon the exercise of stock options during the period. The total cash received from employees as a result of employee stock option exercises during 2010, 2009 and 2008 was $437.4 million, $25.8 million and $50.0 million, respectively.

The total fair value of options vested and expensed during 2010, 2009 and 2008 was $3.6 million, $7.4 million and $13.8 million, respectively.

1987 EMPLOYEE STOCK PURCHASE PLAN | Our 1987 Employee Stock Purchase Plan has two consecutive, overlapping twelve-month offering periods, with a new period commencing on the first trading day on or after May 1 and November 1 of each year and terminating on the last trading day on or before April 30 and October 31. Each twelve-month offering period generally includes two six-month purchase periods. The purchase price at which shares are sold under the ESPP is 85% of the lower of the fair market value of a share of our common stock on (1) the first day of the offering period, or (2) the last trading day of the purchase period. If the fair market value at the end of any purchase period is less than the fair market value at the beginning of the offering period, each participant is automatically withdrawn from the current offering period following the purchase of shares on the purchase date and is automatically re-enrolled in the immediately following offering period.

On May 6, 2010, our stockholders approved an amendment to the ESPP to increase the shares reserved for future issuance by 1 million. As of December 31, 2010, 2.2 million shares were available for future issuance under the ESPP. Sales under the ESPP were 1.0 million shares of common stock at an average price of $16.89 per share for 2010, 1.2 million shares of common stock at an average price of $13.80 per share for 2009 and 1.1 million shares of common stock at an average price of $15.54 per share for 2008.

VALUATION AND EXPENSE INFORMATION | The assumptions used to estimate the fair value of stock options, ESPP shares, RSUs and PRSUs were as follows:


	2010			2009			2008
Stock options:
Expected term (in years)	3.9			5.0			5.0
Expected stock price volatility	31.9		%	34.1		%	37.1		%
Risk-free interest rate	1.6		%	2.2		%	3.0		%
Dividend yield	0.8		%	1.0		%	1.0		%
Weighted-average estimated fair value	$	21.96		$	5.90		$	6.78

ESPP shares:
Expected term (in years)	0.7			0.8			0.7
Expected stock price volatility	31.4		%	50.3		%	51.2		%
Risk-free interest rate	0.3		%	0.4		%	1.2		%
Dividend yield	0.8		%	1.2		%	1.2		%
Weighted-average estimated fair value	$	6.68		$	5.10		$	5.37

RSUs and PRSUs:
Risk-free interest rate	0.8		%	1.2		%	2.6		%
Dividend yield	0.8		%	1.1		%	0.9		%
Weighted-average estimated fair value	$	26.87		$	17.21		$	19.91

For stock options, our expected term represents the weighted average period from the date of grant to exercise, cancellation, or expiration. For ESPP shares, the expected term represents the average term from the first day of the offering period to the purchase date.

Our expected stock price volatility assumption for stock options is estimated using a combination of implied volatility for publicly traded options on our stock with a term of one year or more and our historical stock price volatility. Our expected stock price volatility assumption for ESPP shares is estimated using a combination of implied volatility for publicly traded options on our stock with a term of six months and our historical stock price volatility.

The interest rate used to value stock options and ESPP shares approximates the risk-free interest rate of a zero-coupon Treasury bond on the date of grant with a maturity date that approximates the expected term of the award.

For RSUs and PRSUs, stock-based compensation expense is calculated based on the fair market value of our stock on the date of grant, reduced by the present value of estimated expected future dividends, and then multiplied by the number of RSUs and PRSUs granted. For RSUs, the grant-date value, less estimated pre-vest forfeitures, is expensed on a straight-line basis over the vesting period. PRSUs are expensed using a graded vesting schedule. The vesting period for RSUs and PRSUs is generally four years.

In addition, we apply an expected forfeiture rate when amortizing stock-based compensation expense. During 2009, we changed the expected forfeiture rate from 10.2% to 8.0% based on recent and expected employee turnover rates. This change in accounting estimate resulted in a $3.4 million increase in our stock-based compensation expense ($0.1 million increase in Cost of sales, $1.4 million increase in Research and development expense, and $1.9 million increase in Selling, general and administrative expense) for 2009. Our stock-based compensation expense included in the consolidated statements of income for the three years ended December 31, 2010 was as follows:


(In thousands)	2010			2009			2008

Cost of sales	$	1,241		$	1,933		$	1,407
Research and development expense	27,298			27,067			22,908
Selling, general, and administrative expense	33,579			35,446			24,315
Pre-tax stock-based compensation expense	62,118			64,446			48,630
Income tax benefit	(18,298		)	(18,481		)	(13,844		)
Net stock-based compensation expense	$	43,820		$	45,965		$	34,786

No stock-based compensation was capitalized during any period presented above. As of December 31, 2010, unrecognized stock-based compensation cost related to outstanding unvested stock options, RSUs, PRSUs and ESPP shares that are expected to vest was approximately $122.2 million. This unrecognized stock-based compensation cost is expected to be recognized over a weighted average period of approximately 2.4 years. To the extent the actual forfeiture rate is different from what we have anticipated, stock-based compensation related to these awards will be different from our expectations.

We settle employee stock option exercises, ESPP purchase, RSUs and PRSUs vesting with newly issued common shares.

As of December 31, 2010, we had $2.4 million of California research and development tax credit carry forwards. The California credits can be carried forward indefinitely.

The valuation allowance of $2.7 million established for the year ended December 31, 2010 was primarily due to a California law change providing the option to elect an alternative method to attribute taxable income to California for tax years beginning on or after January 1, 2011. We expect that in years 2011 and beyond, the income subject to tax in California will be lower than under prior tax law and therefore realization of our California deferred tax assets is no longer more likely than not to occur.

The items accounting for the difference between income taxes computed at the federal statutory rate and income tax expense are as follows:

On May 27, 2009, the Ninth Circuit Court of Appeals (the “Court”) issued its ruling holding that stock-based compensation was required to be included in certain transfer pricing arrangements between a U.S. company and its foreign subsidiary. As a result of the ruling, we recognized a discrete income tax expense charge of $11.5 million during 2009 (included in the “Foreign income taxed at different rates” line above). On March 22, 2010, the Court reversed course and affirmed the August 30, 2005 tax court decision that the value of compensatory stock options are not required to be included in the cost sharing agreement between a U.S. company and its affiliates. As a result of the March 2010 decision, we released $11.7 million in 2010 that had been recorded in 2009 based on the Court's original decision.

We file income tax returns with the Internal Revenue Service (“IRS”) and in various U.S. states and foreign jurisdictions. The IRS has completed field examinations of our tax returns for 2002 through 2004 and has issued a notice of proposed adjustment seeking additional taxes of approximately $34.5 million (excluding interest) for those years. We paid $18.0 million to the IRS in 2008, representing a payment on bond for items associated with the IRS field examinations for 2002 through 2004. We are contesting through the administrative process the IRS claims regarding our 2002 through 2004 tax years. The IRS has completed field examinations of our tax returns for 2005 through 2007 and has issued a notice of proposed adjustment seeking additional taxes of approximately $34.2 million (excluding interest) for those years. We are contesting through the administrative process the IRS claims regarding our 2005 through 2007 tax years. Other significant jurisdictions in which we may be subject to examination for fiscal years 2002 forward include China (including Hong Kong), Malaysia, the United Kingdom, and the state of California. We believe that we have made adequate tax payments and/or accrued adequate amounts such that the outcome of these audits will have no material adverse effect on our consolidated operating results. Due to the potential resolution of federal, state and foreign examinations, and the expiration of various statutes of limitations, it is reasonably possible that our gross unrecognized tax benefits may change within the next twelve months. However, given the number of years remaining subject to examination and the number of matters being examined, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits.

The aggregate changes in the balance of gross unrecognized tax benefits for 2010, 2009 and 2008 were as follows:


(In millions)	2010			2009			2008
Balance at beginning of year	$	244.1		$	199.2		$	169.7

Additions based on tax positions related to the current year	39.9			32.5			24.3
Additions for tax positions of prior years	—			13.3			8.7
Reductions for tax positions of prior years	(20.7		)	(0.9		)	(3.5		)
Balance at end of year	$	263.3		$	244.1		$	199.2

As of December 31, 2010, December 31, 2009 and December 31, 2008, the total amount of unrecognized tax benefit that, if recognized, would impact the effective tax rate, is $243.3 million, $222.3 million and $182.2 million, respectively. These amounts are presented net of federal benefits for the deduction of interest and other deductible items.

Estimated interest and penalties related to unrecognized tax benefits are recognized in tax expense. We recognized $2.9 million, $12.8 million, and $5.6 million of interest and penalties in 2010, 2009 and 2008, respectively. The balance of accrued and unpaid interest and penalties was $50.0 million and $47.1 million as of December 31, 2010 and 2009, respectively.

U.S. and foreign components of income before income taxes were:


(In thousands)	2010		2009		2008
U.S.	$	116,362	$	22,091	$	66,276
Foreign	751,465		283,447		352,898

Income before income taxes	$	867,827	$	305,538	$	419,174

Aggregate unremitted earnings of our foreign subsidiaries were $1.6 billion as of December 31, 2010. These earnings, which reflect full provisions for foreign income taxes, are indefinitely invested in foreign operations. If these earnings were remitted to the U.S., they would be subject to domestic and/or foreign taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable.

Note 14: Segment and Geographic Information

We operate in a single industry segment comprised of the design, development, manufacture, and sale of PLDs and related software design tools. Our sales by major geographic area are based on the geographic location of the OEMs or the distributors who have purchased our products. The geographic locations of our distributors may be different from the geographic locations of our end customers.

Note 15: Employee Benefits Plans

ALTERA CORPORATION SAVINGS AND RETIREMENT PLAN | We provide retirement benefits to our eligible U.S. employees, through the Altera Corporation Savings and Retirement Plan (“the 401(k) Plan”). As allowed under Section 401(k) of the Internal Revenue Code, the 401(k) Plan allows tax deferred salary deductions for eligible employees. Our Retirement Plans Committee administers the 401(k) Plan. Participants in the 401(k) Plan may make salary deferrals of up to 50% of their eligible annual salary, limited by the maximum dollar amount allowed by the Internal Revenue Code. For every dollar deferred under the 401(k) Plan, we make a matching contribution equal to 100% up to the first 12% of the salary deferred per pay period

with a maximum of $4,000 per participant in 2010 ($4,000 for 2009 and $3,000 for 2008).

After 3 years of service, all matching contributions are immediately vested. Effective January 1, 2003, participants who reach the age of fifty before the close of the 401(k) Plan year may be eligible to make catch-up salary deferral contributions, limited by the maximum dollar amount allowed by the Internal Revenue Code. Catch-up contributions are not eligible for matching contributions. Total contributions to the 401(k) Plan were $4.5 million, $4.7 million, and $3.8 million in 2010, 2009 and 2008, respectively, and were expensed as incurred.

ALTERA CORPORATION NON-QUALIFIED DEFERRED COMPENSATION PLAN | We allow our U.S.-based officers and director-level employees to defer a portion of their compensation under the Altera Corporation Non-Qualified Deferred Compensation Plan (“NQDC Plan”). Our Retirement Plans Committee administers the NQDC Plan. As of December 31, 2010, there were approximately 114 participants in the NQDC Plan who self-direct their investments in the NQDC Plan, subject to certain limitations. In the event we become insolvent, the NQDC Plan assets are subject to the claims of our general creditors. Since the inception of the NQDC Plan, we have not made any contributions to the NQDC Plan and we have no commitments to do so in the future. There are no NQDC Plan provisions that provide for any guarantees or minimum return on investments. NQDC Plan participants are prohibited from investing NQDC Plan contributions in Altera common stock. The balance of the NQDC Plan assets and related obligations was $74.2 million and $69.9 million as of December 31, 2010 and December 31, 2009, respectively.

Investment income or loss earned by the NQDC Plan is recorded as (Gain) loss on deferred compensation plan securities in our consolidated statements of income. The investment (gain) loss also represents a (increase) decrease in the future payout to participants and is recorded as Compensation expense (benefit) - deferred compensation plan in our consolidated statements of income. Compensation expense (benefit) associated with our NQDC Plan obligations is offset by (gain) loss from related securities. The net effect of investment income or loss and related compensation expense or benefit has no impact on our income before income taxes, net income, or cash balances.

RETIREE MEDICAL PLAN | We sponsor a retiree medical plan providing medical benefits to eligible U.S. retirees and their spouses. Prior to January 2009, benefits were available to employees hired on or before July 1, 2002 who retired from Altera at or after age 55 if they had at least 10 years of service, and who were age 40 or older as of January 1, 2005.

In January 2009, we modified the retiree medical plan to:


•	Eliminate coverage for new retirees after January 1, 2010;


•	Suspend retiree coverage at the Medicare entitlement age of 65; and


•	Increase the cost sharing provisions for covered spouses from 50% to 75% of the policy premium.

Employees meeting certain eligibility requirements were provided the option of retiring and enrolling in the retiree medical plan by December 31, 2009 or electing a cash payout based on age and years of service. As a result of the plan modifications, our accumulated postretirement benefit obligation has been substantially eliminated. The substantive termination of the retiree medical plan results in a gain of approximately $6.5 million, net of unrecognized actuarial losses of approximately $1.3 million. The gain was recognized as a reduction of compensation and benefits costs ($0.3 million reduction in Cost of sales, $3.6 million reduction in Research and development expense, and $2.6 million reduction in Selling, general and administrative expense) in 2009. As of December 31, 2010, the accumulated postretirement benefit obligation (a component of Other non-current liabilities in our consolidated balance sheets) is $0.2 million compared with $0.3 million as of December 31, 2009. The remaining accumulated postretirement benefit obligation will be paid to remaining retiree medical plan participants over varying periods of up to four years.

OTHER EMPLOYEE BENEFIT PLANS We offer to U.S. and non-U.S. employees participation in a Service Award Program (“SAP”). The SAP provides employees with one to four weeks of additional paid vacation upon their achievement of five, ten, fifteen, twenty and twenty-five year service anniversaries. The following table presents the total long-term and short-term liabilities for this program, which are included in Accrued compensation and related liabilities and Other non-current liabilities.

Accrued compensation and related liabilities	$	2,527	$	2,947
Other non-current liabilities	5,858		5,219
	$	8,385	$	8,166

Note 16: Long-term Credit Facility

On August 31, 2007, we entered into a five-year $750 million unsecured revolving credit facility (the “Facility”) that is scheduled to expire on August 31, 2012. Under certain circumstances, upon our request and with the consent of the lenders, the commitments under the Facility may be increased up to an additional $250 million and the expiration date of the Facility may be extended annually for additional one year periods.

Our total borrowings under the Facility as of December 31, 2010 and 2009 were $500 million. Borrowings under the Facility bear interest at either a Eurodollar rate (“LIBOR”) or a Prime rate, at our option, plus an applicable margin based upon certain financial ratios, determined and payable quarterly. The interest rate as of December 31, 2010 and 2009 were LIBOR plus 0.35%, and LIBOR plus 0.425%, respectively. In addition, we pay a facility fee on the entire Facility. This facility fee varies with certain financial ratios and was 0.10% and 0.125% as of December 31, 2010 and 2009, respectively. The principal amount of borrowings, together with accrued interest, is due on the maturity date of August 31, 2012. As of December 31, 2010, $250 million is available under the Facility.

Interest expense recognized under the Facility represented the substantial portion of Interest expense on our consolidated income statements for 2010, 2009 and 2008.

The terms of the Facility require compliance with certain financial covenants that require us to maintain certain financial ratios related to interest coverage and financial leverage. As of December 31, 2010, we were in compliance with all such covenants.

Note 17: Restructuring Charges

The restructuring charges for 2009 are included in our consolidated statements of income as follows:

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Altera Corporation:

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Altera Corporation and its subsidiaries at December 31, 2010 and December 31, 2009, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.

During the first and third quarters of 2009, we recorded restructuring charges of $5.2 million and $4.8 million, respectively.

During the third quarter of 2009, we reduced our allowance for doubtful accounts based on our sustained favorable collection experience and estimated probable credit losses in our existing accounts receivable based on analysis of current aging, economic indicators and customer conditions. This change in accounting estimate reduced our Selling, general and administrative expense by $2.3 million.

During the third quarter of 2009, we changed the expected forfeiture rate that we apply when amortizing stock-based compensation cost from 10.2% to 8.0% based on recent and expected employee turnover rates. This change in accounting estimate resulted in a $3.4 million increase in our stock-based compensation expense ($0.1 million increase in Cost of sales, $1.4 million increase in Research and development expense, and $1.9 million increase in Selling, general and administrative expense).

In January 2009, we modified our retiree medical plan. As a result, our accumulated postretirement benefit obligation has been substantially eliminated. The substantive termination of the retiree medical plan resulted in a gain of approximately $6.5 million, net of unrecognized actuarial losses of approximately $1.3 million. The gain was recognized as a reduction of compensation and benefits costs ($0.3 million reduction in Cost of sales, $3.6 million reduction in Research and development expense, and $2.6 million reduction in Selling, general and administrative expense).

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

None.

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in the reports we file or submit pursuant to the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management, with the participation of the Chief Executive Officer and Chief Financial Officer, has performed an evaluation of our disclosure controls and procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2010, our disclosure controls and procedures were effective.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Internal control over financial reporting is the process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that:


(i)	pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of assets;


(ii)	provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with the authorization of our management and directors; and


(iii)	provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. 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 established policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2010. In making this assessment, it used the criteria based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission in “Internal Control - Integrated Framework.” Based on the results of this assessment, management (including our chief executive officer and our chief financial officer) has concluded that, as of December 31, 2010, our internal control over financial reporting was effective.

The effectiveness of our internal control over financial reporting as of February 14, 2010 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included in this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a - 15(f) and 15(d) - 15(f) under the Exchange Act) that occurred during the fourth quarter of fiscal 2010 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
