PART I

|ITEM1. |  | BUSINESS.
|------ |  | ---------

Founded in 1983, Altera
Corporation designs, manufactures, and markets: (1) programmable logic devices, or PLDs; (2) HardCopy® structured application-specific integrated circuit, or ASIC, devices; (3) pre-defined design building blocks known as intellectual property, or IP cores; and (4) associated
development tools. Our headquarters facility is located at 101 Innovation Drive, San Jose, California 95134, and our web site is www.altera.com. Our common stock trades on the NASDAQ Global Market under the symbol ALTR.

Our PLDs, which consist of field-programmable gate arrays, or FPGAs, and complex programmable logic devices, or CPLDs, are semiconductor integrated
circuits, or chips, that are manufactured as standard chips that our customers program to perform desired logic functions within their electronic systems. Our HardCopy structured ASIC devices, which offer greatly reduced die size due to the removal
of programmable routing and other circuits in our highest density FPGAs, enable our customers to transition from a high-density FPGA to a low-cost non-programmable implementation of their designs for volume production. Because they are customized
only on the last few mask layers, HardCopy devices deliver performance that is comparable to traditional ASIC devices, but with reduced development costs and shorter production lead times. 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.

Digital Logic Overview

Three principal types of digital integrated circuits are used in most electronic systems: (1) processors, (2) memory, and (3) logic.



| | § |  | Processors, which include microprocessors, microcontrollers, and digital signal processors, are typically used for control, central computing tasks, and signal
processing;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | § |  | Memory is used to store programming instructions and data; and
| | - |  | --------------------------------------------------------------



| | § |  | Logic is typically used to manage the interchange and manipulation of digital signals within a system.
| | - |  | ------------------------------------------------------------------------------------------------------

While system designers employ a relatively small number of standard architectures to meet their processor and memory needs, they require a wide variety of
logic circuits to differentiate their end products.

##### Table of Contents

The majority of the digital logic market is made up of three product sub-segments: (1) ASICs;
(2) application-specific standard products, or ASSPs; and (3) PLDs. In a broad sense, all of these products are competitive with each other as they generally 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 the extent to which they may be directly competitive for particular applications. The table below summarizes key characteristics of ASIC, ASSP, and PLD
products from the perspective of the end customer.

ASICs, also frequently referred to as standard cells, are defined by the end customer and
customized during manufacturing at the chip fabrication facility. As a result, a given ASIC has a fixed function for use by a single customer in a single application. ASSPs are defined by the ASSP supplier and sold as standard devices that usually
cannot be customized by the end user. Rather than being built for a single customer as in the case of an ASIC, an ASSP is built for a specific type of application and is typically targeted and sold to a limited number of customers. For simplicity,
an ASSP may be viewed as an ASIC developed for more than one customer. In contrast to the fixed nature of both ASICs and ASSPs, PLDs are customized by the end customer and hence can be used in a wide range of applications. As a result, a given PLD
is typically sold to hundreds or thousands of customers.

The inherent flexibility of PLDs provides significant advantages to the end
customer over ASICs, including design change simplicity, shorter design cycles, and lower development cost. In contrast to ASIC users, PLD users program their design directly into the PLD and can have custom chips that are fully functioning and
verified at the time the design is completed, thereby bypassing the lengthy and complex cycles involved in the verification and fabrication of ASICs. As a result of user programmability, PLD customers may experiment with and revise their designs in
a relatively short amount of time and with minimum development cost. The ease-of-use and time-to-market advantages of PLDs are complemented by the added benefit of field upgradeability, which generally enables PLD users to modify the PLD design
after the electronic system has been shipped.

Due to their programmability, however, PLDs generally have a larger die size and associated
higher per-unit cost when compared to ASICs. While the customized manufacturing of ASICs can result in more optimized chip performance and lower per-unit cost than PLDs, ASICs require higher up-front costs and longer manufacturing lead times.

Historically, due to their lower per-unit costs, ASICs have been viewed as more cost effective than PLDs for large-volume, low-cost
applications such as consumer electronics. Consequently, the unit volume of a PLD implementation is typically lower than that for an ASIC implementation. Additionally, some customers may choose to prototype with PLDs for initial engineering
development and then re-design to an ASIC in volume production for lower per-unit cost. While such re-designs have always been an aspect of the PLD business, we believe that the following factors are driving electronic systems manufacturers to use
PLDs for their systems entire life cycle: (1) the continual reduction in the price premium of programmable logic; (2) the ever-shortening product life cycle of many electronic systems; and (3) the use of more advanced chip
manufacturing technology, which heightens the failure risk of ASICs and the up-front costs of design, verification and mask development, known as non-recurring engineering costs.

ASSPs have been used in applications where specific fixed functions are needed and where little differentiation is required, such as in implementing
certain electronic industry standards. However, the fixed functionality of ASSPs limits the range of applications they can address. In contrast to ASSPs, the flexibility found in PLDs allows users to define circuitry to suit their value-added and
differentiated system architecture, rather than restrict their system

##### Table of Contents

architecture based upon the ASSP manufacturers device specification. Furthermore, the emergence of IP design blocks in PLDs has allowed the
implementation of standardized functions otherwise performed by ASSPs.

We believe that the adoption of more advanced chip manufacturing
technology, which is increasing the total cost of chip development, is reducing the cost advantage of ASICs and ASSPs. The cost and time for us to develop a PLD is comparable to the cost and time for others to develop an ASIC or ASSP. Since each of
our PLDs is sold to hundreds or thousands of customers, we generally spread development costs and generate revenue across a wide customer base. In contrast, ASIC and ASSP suppliers build fixed, custom chips for a single customer or for a single
application. Because it is increasingly difficult for ASIC and ASSP suppliers to identify opportunities that generate enough revenue to compensate for the high development costs, we believe that ASIC suppliers are imposing ever-higher up-front costs
and minimum order quantities on customers, and ASSP manufacturers may be developing fewer products.

Strategy and Competition

We believe that the increasing cost associated with the use of advanced chip manufacturing technology is driving the development and
use of standard, programmable digital integrated circuits. As with microprocessors and memory, PLDs provide the flexibility for the end user to change and define circuits without incurring the cost, risk and delays of custom chip fabrication.
Consequently, we believe that customers will increasingly use PLDs for both prototyping and production rather than ASICs or ASSPs, despite the higher per-unit cost of PLDs.

In order to capture a larger percentage share of the semiconductors purchased by our customers, we are focused on providing the most advanced programmable
solutions. To accomplish this goal, we strive to offer our customers:



| | § |  | PLDs with the speed, density, functionality, and package types to meet their specific needs;
| | - |  | --------------------------------------------------------------------------------------------



| | § |  | PLDs optimized for low-cost and high-volume applications;
| | - |  | ---------------------------------------------------------



| | § |  | HardCopy devices that enable our customers to easily move from our largest PLDs to a low-cost structured ASIC implementation of their designs;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| | § |  | Optimized, pre-verified system-level IP cores to speed their design process;
| | - |  | ----------------------------------------------------------------------------



| | § |  | State-of-the-art development tools that offer low cost, ease-of-use and compatibility with other industry-standard electronic design automation, or EDA, tools; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | § |  | A complete customer support system.
| | - |  | -----------------------------------

We believe that the greatest opportunity for our growth is displacing ASICs and ASSPs. As a result, 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 high volume customers and end markets. We compete with other PLD vendors to realize this opportunity and for market share within the PLD market. The programmable logic market is highly concentrated with two vendors
accounting for a majority of the total market: ourselves and Xilinx, Inc. Using publicly available data and information obtained from Gartner Dataquest, we estimate that the smaller vendors, including Lattice Semiconductor Corporation and Actel
Corporation, together comprise approximately 15% of the PLD market. Within the PLD market, sales of FPGAs and CPLDs constitute the majority of revenues. CPLDs and FPGAs are often viewed as two distinct sub-segments of the PLD market and, due to
product differences, generally do not compete directly for the same customer designs. Altera was an early entrant in the CPLD sub-segment and, based on our estimates, we believe that in 2006 and 2005 we had a 42% share in the CPLD sub-segment, 44%
in 2004, and 47% in 2003. The FPGA sub-segment has outgrown the CPLD sub-segment. FPGAs now comprise approximately 75% of total PLD sales, and it is generally accepted by participants and observers of the industry that the FPGA sub-segment will
continue to be the fastest growing sub-segment of the PLD market. Based on our estimates, we believe that in 2006 we had a 33% share in the FPGA sub-segment, up from 32% in 2005, 30% in 2004 and 29% in 2003, and that maintaining or increasing market
share in this sub-segment is important to our long-term growth.

Competition among PLD vendors is most intense in the design-win
phase of the customers design. The design-win phase refers to the customers selection of a particular vendors product for use in the customers electronic system. Because each vendors product offering is proprietary, the
cost to switch PLD devices after a system has been designed and prototyped is very high. Therefore, customers rarely switch PLD vendors after this initial selection for a particular



5

##### Table of Contents

design. From the time a design win is secured it can be as long as two years, and sometimes longer, before the customer starts volume, or production,
purchases of our devices. Typically, the customer selects the PLD vendor relatively early in the customers design program. It generally takes several years from that point before the customer has completed its entire system design, built
prototypes, sampled the marketplace for customer acceptance, made any modifications, and established volume manufacturing capacity. Thus, movements in PLD market share often occur some time after the change in relative competitiveness that gave rise
to the market share shift. Because of this time lag, market share is a lagging indicator of relative competitive strength. Because it is extremely difficult to forecast the degree of success or timing of a customers program, and because the
end markets are so fragmented (we have over 14,000 PLD customers), it is difficult even for PLD vendors to gauge their competitive strength in securing design wins as of a particular point in time.

Principal competitive factors in the PLD sub-segment include:



| | § |  | Technical innovation;
| | - |  | ---------------------



| | § |  | Device performance and features;
| | - |  | --------------------------------



| | § |  | Capability of software development tools and IP cores;
| | - |  | ------------------------------------------------------



| | § |  | Pricing and availability;
| | - |  | -------------------------



| | § |  | Quality and reliability;
| | - |  | ------------------------



| | § |  | Technical service and customer support;
| | - |  | ---------------------------------------



| | § |  | Manufacturing and operational competence; and
| | - |  | ---------------------------------------------



| | § |  | 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 our installed base of software development systems may provide some competitive advantage. We have
been able to introduce new product families that, as compared to their predecessors, provide greater functionality at a lower price for any given density because of unique architectural innovation and advanced technologies.

We also believe that in certain circumstances these new product families compete favorably against ASICs and ASSPs, as well as against other types of
chips such as microcontrollers, microprocessors, and digital signal processors. Some of the functionality offered by these other types of chips can be implemented in 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 are characterized by
rapid technological change, rapid rates of product obsolescence, and price erosion. All of these factors may adversely affect our future operating results. For a discussion of risk factors associated with our strategy and competition, see Item
1A: Risk Factors  Our failure to compete successfully in the highly competitive semiconductor industry would adversely affect our financial results and business prospects and Our failure to define, develop,
and manufacture technologically-advanced products would adversely affect the success and growth of our company.

Products

Our products consist primarily of devices, IP cores, and proprietary development tools. A brief overview of these products follows.

DEVICES

Our devices fall into the following four categories: (1) FPGAs, (2) CPLDs, (3) low-cost HardCopy structured ASIC devices, and (4) configuration devices that store the programming code for our FPGAs. These devices span
multiple

##### Table of Contents

architectures and device families, with numerous product options. Each device family offers unique functional benefits and differing density and performance
specifications. Sales of FPGAs accounted for 71% of our total sales in 2006, 70% in 2005, and 68% in 2004. Sales of CPLDs accounted for 19% of our total sales in 2006, 20% in 2005, and 23% in 2004. Sales of our other products accounted for 10% of
our total sales in 2006, 10% in 2005, and less than 10% of our total sales in 2004. Some of our latest device families, which are typically designed into new end equipment, are summarized and described below. Certain of our more mature device
families, which are not now typically designed into new end equipment but may still comprise significant portions of our total revenue, have been omitted from the descriptions below.

Stratix II and Stratix III High-End, System-Level FPGAs

Our Stratix®
product families are built using advanced CMOS process technology and address a broad range of applications in communications, computing and storage, consumer, and industrial markets. Architectural innovations within Stratix FPGAs help provide high
logic density and performance and low power consumption, while offering high speed and flexible embedded system functionality such as memory and digital signal processing (DSP) blocks. Additionally, our Stratix II GX FPGA devices offer advanced
transceiver capabilities for applications that require reliable, multi-gigabit data transfer rates. Our Stratix III family is planned for initial shipment in 2007 and offers the lowest power consumption amongst high performance FPGAs in the
marketplace.

Cyclone II Low-Cost, High-Volume FPGAs

Our Cycloneproduct families are built using advanced CMOS process technology and bring programmable flexibility to cost-sensitive
applications across a vast array of end markets within the communications, computing and storage, consumer, and industrial markets. Architectural innovation allows Cyclone devices to combine a low-cost structure with abundant device resources,
making them ideal for high-volume applications across all our served markets in areas such as digital set-top boxes, DVD player/recorder systems, automotive telematics, and flat panel televisions.

MAX II CPLDs

Our MAX® CPLD product families are instant-on, non-volatile
devices that address a wide range of high-speed glue logic functions found in a broad range of electronics equipment in the communications, computing and storage, consumer, and industrial markets. Glue logic enables the interaction of multiple
subsystem components. Our current generation MAX II devices are based on a newly developed and revolutionary architecture that reduces costs by up to 50 percent or more, consumes 90 percent less power, and increases performance by as much as 50
percent over the previous generation MAX family.

HardCopy and HardCopy II Structured ASIC Devices

Our HardCopy and HardCopy II (HardCopy) products offer customers a migration path from the highest density FPGA families to a low-cost structured ASIC
device for high-volume production applications. In contrast to traditional cell-based ASICs, in which every mask layer is custom and unique to the customers design, structured ASICs share a common set of base layers and the
customers design is implemented in the device by customizing only the last few mask layers. For a given process technology, structured ASIC devices deliver nearly the performance of comparable ASICs, but with reduced development costs and
shorter production lead-times.

HardCopy device base arrays are developed from equivalent FPGAs by removing the configuration circuitry,
programmable routing, and programmability for logic and memory. This scheme reduces the die size while maintaining compatibility with the FPGA architecture, providing seamless migration of the customer design to a HardCopy device. As a result,
HardCopy devices extend the flexibility and time-to-market advantages of high-density FPGAs, which are used typically for prototyping, to high-volume, more cost-sensitive applications historically served by traditional cell based ASICs.

INTELLECTUAL PROPERTY CORES

IP cores are pre-verified building blocks that implement standard system-level functions that customers incorporate in their PLD design by using our
proprietary development software. Soft IP cores available for use in our devices consist

##### Table of Contents

of our Nios® and Nios II soft core embedded processors and our portfolio of
MegaCore® functions, which we license to our customers, and our Altera Megafunction Partners Program, or AMPPSM, cores, which are pre-verified by us and licensed to our customers by third parties.

The Nios and Nios II embedded processors utilize a reduced instruction set computing, or RISC, architecture and are a cost-competitive and flexible
alternative to discrete microcontroller solutions. The Nios embedded processors can be efficiently implemented in all of our newer FPGA devices. The Nios II soft core embedded processor provides up to a 300% improvement in price/performance when
compared to the original Nios embedded processor and competes favorably with many discrete microcontrollers.

With IP cores, system
designers can focus more time and energy on improving and differentiating the unique aspects of their system design, rather than spending time designing common off-the-shelf functions. IP cores are essential to providing our customers solutions that
enable higher levels of integration and faster time-to-market. Today, we offer a broad range of soft IP cores for various system blocks for DSP algorithms, bus interfaces, memory controllers, telecommunications, data communications, microprocessors,
and peripherals. Prior to licensing a soft IP core, customers may download an encrypted soft IP core from our web site and verify that it works in their own system design. While licensing soft IP cores represents a small portion of our total
revenues, 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

Our proprietary development tools, consisting primarily of the Quartus® II software, enable our customers to successfully
complete all necessary PLD design steps. Our tools enhance engineering productivity by facilitating design entry, design compilation, design verification, and device programming during the initial design and subsequent design revisions.

Our development tools can be used on a variety of computing platforms and have built-in interfaces with other engineering design software, thus making
it possible for customers to utilize their existing design environment. Our Quartus II software development tools run under the Microsoft Windows, UNIX (including Solaris and HP-UX), and Linux operating environments. Our development tools also
provide interfaces to many industry-standard EDA tools, including those offered by Cadence Design Systems, Inc., Mentor Graphics Corporation, Synopsys, Inc., and Synplicity, Inc.

Like soft IP cores, our development tools generate less than 10% of our total revenues, 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 ASIC and ASSP vendors as well as other PLD vendors.

Research and Development

Our research and development activities have focused primarily on PLDs and
on associated IP cores, development software, and hardware. We have developed these related products in parallel to provide comprehensive design support to customers. As a result of our research and development efforts, we have introduced during the
past three years a number of new families, including the Stratix II, Stratix II GX, Cyclone II, MAX II, and HardCopy II device families, as well as major enhancements to our IP core offerings and the Quartus II development platform.

Our research and development expenditures were $248.7 million in 2006, $209.8 million in 2005, and $181.9 million in 2004. Research and development
costs are charged to expense as incurred. We intend to continue to spend substantial amounts on research and development in order to continue to develop and achieve market acceptance of our new products. For a discussion of risk factors associated
with our research and development efforts, see Item 1A: Risk Factors  Our failure to define, develop, and manufacture technologically-advanced products would adversely affect the success and growth of our
company.

Patents, Trademarks, and Licenses

We generally rely on intellectual property law, including patent, copyright, trademark, and trade secret laws, to establish and maintain our proprietary rights in products and technology. We have increased investment
in intellectual property protection in the last several years and, as of December 29, 2006, we owned more than 1,300 United States



8

##### Table of Contents

and 184 foreign patents. We also have more than 900 patent applications currently pending. Also, we have used, registered, and applied to register certain
trademarks and service marks to distinguish our products, technologies, and services from those of our competitors in the United States and foreign countries. In addition, we file registrations in the United States under the Semiconductor Chip
Protection Act to protect our chip designs.

We have entered into technology licensing agreements that give us rights to design,
manufacture, and sell products using certain intellectual property owned by others. In July 2001, we entered into a settlement agreement with Xilinx under which we settled all pending patent litigation. As part of the settlement agreement, we
entered into a royalty-free patent cross license agreement with Xilinx, including a prohibition of further patent litigation between the two companies through July 2006. In connection with the settlement agreement, we paid Xilinx a one-time payment
of $20.0 million. Similarly, in July 2001, we entered into a settlement agreement with Lattice under which we settled all pending patent litigation. As part of the settlement agreement, we entered into a royalty-free patent cross license agreement
with Lattice, including a multi-year prohibition of further patent litigation between the two companies. No payments were made by Altera or Lattice as part of the settlement.

When necessary, we seek to enforce our intellectual property rights. For example, in 1999, we brought an action against Clear Logic, Inc. for infringement
of our mask work registration rights and for interfering with our license agreements with our customers. A jury in the United States District Court for the Northern District of California decided in our favor on both issues in October 2002, and
the jury verdict was affirmed on appeal by the Ninth Circuit Court of Appeals in September 2005. Although we believe that protection afforded by our intellectual property rights has value, the rapidly changing technology in the semiconductor
industry makes our future success dependent primarily on the innovative skills, technological expertise, and management abilities of our employees rather than on our patent, trademark, or other proprietary rights. For a discussion of risk factors
associated with our patents, trademarks, and licenses, see Item 1A: Risk Factors  The failure of our intellectual property rights to provide meaningful protection from our competitors could harm our competitive
position and Intellectual property infringement claims could adversely affect our ability to manufacture and market our products.

Marketing and Sales

We market our products worldwide through a network of distributors, independent
sales representatives, and direct sales personnel. From time to time, we may add or remove independent sales representatives or distributors from our selling organization as we deem appropriate.

ALTERA DISTRIBUTORS

We engage distributors in all major geographic markets that we serve. 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, which can be terminated by either party in a relatively short period of time. The main roles of our independent distributors are to provide demand creation for the broad base of
customers and order fulfillment services for most of our customers.

All of our distributors stock inventory of our products. The
distributors purchase products from us at a set distributor cost denominated in U.S. dollars. Title and risk of loss generally transfer upon shipment from our stocking locations, which are primarily located at the independent subcontractors we
employ for test and assembly services in the Asia Pacific region or our warehouse in San Jose. Upon shipment to the distributor, we generally defer revenue on the sale 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 titled 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 is generally lengthy 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 into prototyping or production, the order fulfillment process begins. Regardless of whether Altera, an independent sales representative, or the distributor
created the demand, a local distributor will process and fulfill over 90% of all orders from customers. Our distributors are the legal sellers of the products and therefore bear all risks, such as credit loss, inventory shrinkage and theft, and
foreign currency fluctuations that are generally related to the sale of commercial goods.

##### Table of Contents

In accordance with our distribution agreements and industry practice, we have granted our distributors
the contractual right to return certain amounts of unsold product on a periodic basis and also to receive price concessions for unsold product in the case of a subsequent decrease in list prices. We also provide price concessions to our distributors
for a portion of their original purchase price in order for them to address individual negotiations involving high-volume or competitive situations. Typically, a customer purchasing a small quantity of product for prototyping or development from a
distributor will pay list price. However, a customer using our products in volume production, purchasing thousands or even hundreds of thousands of units, will often competitively negotiate a substantial price discount from the distributor. Under
such circumstances, the distributor will often negotiate and receive a price concession from Altera. In recent years, such concessions have exceeded 60% of list price on average. This is a standard practice in the semiconductor industry and we
provide some level of price concession to every distributor.

Total sales are the sum of our own direct sales to OEMs and our
distributors resales of Altera products. For the fiscal year ended December 29, 2006, worldwide sales through distributors for subsequent resale to OEMs or their subcontract manufacturers accounted for 93% of total sales. Arrow
Electronics, Inc., or Arrow, continues to be our largest distributor. Arrow on a worldwide basis accounted for 47% of total sales in 2006, 44% in 2005, and 46% in 2004. Our second largest distributor, Altima Corporation, accounted for 15% of total
sales in 2006, 17% in 2005, and 16% in 2004. No other distributor accounted for greater than 10% of total sales in 2006 or 2005. In 2004, a third distributor, Paltek Corporation, accounted for 10% of total sales. In March 2006, we terminated our
distribution relationship with Paltek Corporation.

For a discussion of the risk factors associated with our distribution model, see
Item 1A: Risk Factors  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 would materially reduce our
future sales and Conditions outside the control of our independent subcontractors and distributors may impact their business operations and thereby adversely interrupt our manufacturing and sales processes. See
also Note 2  Significant Accounting Policies  Concentrations of Credit Risk to our consolidated financial statements.

ALTERA SALES, MARKETING, AND CUSTOMER SUPPORT

Altera also maintains a dedicated global sales and marketing organization to create customer demand and manage our network of distributors and independent sales representatives. In general, we focus our direct demand
creation efforts on a limited number of key accounts, as well as providing technical, business, and marketing support to distributors and independent sales representatives. Independent sales representatives are mostly located in North America and in
select European countries. Independent sales representatives create demand and provide customer support in a defined territory and, in many cases, with a defined set of customers. They stock no inventory and provide no order fulfillment services.
All of our contracts with independent sales representatives may be terminated by either party in a relatively short period of time.

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

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

No single end
customer accounted for more than 10% of our total sales in 2006, 2005 or 2004.

INTERNATIONAL SALES

International sales, which consist of all sales outside of North America, constituted 76% of total sales in 2006, 75% of total sales in
2005, and 71% of total sales in 2004. Sales to Japan accounted for 23% of total sales in 2006, and 25% of total sales in 2005 and 2004. Except for the United States and Japan, no other country accounted for sales in excess of 10% of total sales
during 2006, 2005, or 2004. We expect international sales to continue to increase as a percentage of

##### Table of Contents

our total sales in the future. All of our sales to foreign entities are denominated in United States dollars. For a detailed description of our sales by
geographic region, see Item 7: Results of Operations  Sales by Geography and Note 10  Segment and Geographic Information to our consolidated financial statements. For a discussion of the risk factors associated
with our foreign operations, see Item 1A: Risk Factors  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 and Our business is subject to tax risks associated with being a multinational corporation.

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 on December 29, 2006, was approximately $614.0 million, compared to $522.7 million on December 30, 2005.

Historically, backlog has been a poor predictor of future customer demand. While our backlog can increase during periods of high demand and supply
constraints, purchasers may generally cancel product orders up to 30 days prior to the scheduled delivery date without incurring significant cancellation penalties. Further, we generally defer recognition of revenue on shipments to distributors
until the product is resold. For all of these reasons, backlog as of any particular date should not be used as a predictor of future sales.

Manufacturing

WAFER SUPPLY

Die, cut from silicon wafers, are the essential components of all our devices and a significant portion of the total device cost. Our manufacturing
strategy is known as a fabless business model since we do not directly manufacture our silicon wafers. Instead, our silicon wafers are produced by independent semiconductor foundries. This enables us to take advantage of these
suppliers high-volume economies of scale and also gives us direct and timely access to advanced process technology. We purchase nearly all of our silicon wafers from Taiwan Semiconductor Manufacturing Company, or TSMC, an independent
semiconductor foundry. We have no formalized long-term supply or allocation commitments from TSMC. The remaining portion of our silicon wafers are produced by Sharp Corporation in Japan. In the past, we have used other foundry vendors, and we may
establish additional foundry relationships as they become economically beneficial or technically necessary. For a discussion of risk factors associated with our wafer supply arrangements, see Item 1A: Risk Factors  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, Shortages of, and/or increased costs
for, our silicon wafers could lower our gross margins, reduce our sales, or otherwise materially disrupt our business, The manufacture of our products is complex, and the foundries on which we depend may not achieve the necessary
yields or product reliability that our business requires, and Conditions outside the control of our independent subcontractors and distributors may impact their business operations and thereby adversely interrupt our manufacturing
and sales processes.

TESTING AND ASSEMBLY

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

The wafers are then shipped to various assembly suppliers in Asia, where good die are separated into individual chips that are then encapsulated in
packages. We employ a number of independent suppliers for assembly purposes. This enables us to take advantage of these subcontractors high-volume economies of scale and supply flexibility, and gives us direct and timely access to advanced
packaging technology. We purchase almost all of our assembly services from Amkor Electronics, Inc., in Korea and the Philippines, and Advanced Semiconductor Engineering, Inc., or ASE, in Malaysia and Taiwan.

##### Table of Contents

Following assembly, each of the packaged units receives final testing, marking, and inspection prior to
being packaged for storage as finished goods. We obtain almost our entire final test and back-end operation services from Amkor and ASE. Final testing by these assembly suppliers is accomplished through the use of 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 at our subcontract test and assembly partners located in Asia with a smaller portion located at our corporate facility in San Jose, California. On our behalf, these suppliers also ship our products to OEMs and distributors.

For a discussion of risk factors associated with our testing and assembly arrangements, see Item 1A: Risk Factors  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 and Conditions outside the
control of our independent subcontractors and distributors may impact their business operations and thereby adversely interrupt our manufacturing and sales processes.

|ITEM1A. |  | RISK FACTORS.
|------- |  | -------------

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

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 will
depend on our ability to provide our customers with solutions offering greater value than solutions 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 vendors of ASICs, ASSPs, microcontrollers, and digital signal
processors, we indirectly compete against vendors of these products. Many of these vendors, including International Business Machines Corporation and Texas Instruments Inc., have substantially greater 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 not be able to displace these vendors in the targeted applications and densities.
Further, other programmable logic vendors are targeting these applications and may be successful in securing market share from us. Moreover, some of our customers have historically used standard cell technologies to achieve greater integration in
their systems; this may not only impede our efforts to penetrate the markets for ASICs, ASSPs, microcontrollers, and digital signal processors, but may also displace our products in the applications that we presently serve.

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

As a semiconductor company, we operate in a dynamic market characterized by rapid technological change. The manufacture of our products
is 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 not result in the timely introduction of competitive new products, or enhancements to existing products. 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 II and Cyclone II families, are manufactured on a 90-nanometer all-layer-copper interconnect process. Our next
generation product families will be manufactured on a 65-nanometer all-layer-copper interconnect process for which we have no production history. We will continue to transition our fabrication process arrangements to smaller circuit geometries. The
use of advanced process technology entails inherent technological risks and start-up difficulties that can adversely affect research and development spending, yields, product costs, and timeliness of delivery of our products.

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. The remaining portion of our silicon wafers are produced by Sharp Corporation in Japan. Silicon wafer production facilities have at any given time a fixed capacity, the allocation of which is determined solely by our vendors and
over which we have no direct control. We have no formalized long-term supply or allocation commitments from our foundry suppliers. Our operations would be disrupted if TSMC terminates its relationship with us and we are unable to arrange a
satisfactory alternative to fulfill customer orders on a timely basis and in a cost-effective manner.

To ensure the continued supply of
wafers, we may establish other sources of wafer supply for our products as these arrangements become economically advantageous or technically necessary. However, there are only a few foundry



14



---

##### Table of Contents

vendors that have the capabilities to manufacture our most advanced products. If we engage alternative sources of supply, we may encounter start-up
difficulties and incur additional costs. Also, shipments could be delayed significantly while these sources are qualified for volume production.

Furthermore, as a result of our reliance 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.

Shortages of, and/or increased costs for, our silicon wafers and assembly material 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 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.

The
manufacture of our products is complex, and the foundries on which we depend may not achieve the necessary yields or product reliability that our business requires.

The manufacture of our products is a highly complex and precise process, requiring production in a tightly controlled environment. In addition to sufficient foundry manufacturing capacity and wafer prices, we depend
on good production yields (the number of good die per wafer) and timely delivery of silicon wafers to meet our customers demand for products and to 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 is common in the semiconductor industry, we have experienced, and may experience, from time to time,
problems with achieving acceptable production yields and timely delivery from our foundry vendors.

Difficulties in production yields can
often occur when we begin production of new products, 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, from time to time, 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 experience delays from time to time in processing some of our products. These difficulties and delays can potentially result in significantly higher costs and lower product availability.

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 not be able 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. For example, because we rely heavily on TSMC to produce a significant portion
of our silicon wafers, earthquakes or other natural disasters in Taiwan and Asia generally could limit our supply of silicon wafers and thereby harm our business, financial condition, and results of operation.

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, are also located near major earthquake faults. Any catastrophic event, such as an earthquake or other natural disaster, could significantly impair our ability and the ability of our independent subcontractors to meet
product design deadlines, maintain our records, pay our suppliers, or manufacture or ship our products.

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 placed on our distributors and based on our inventory levels, manufacturing cycle times, component lead times, and projected production yields. We aggregate and disseminate all of this information electronically over
a complex global communications network. Our ability to aggregate demand and to adjust our production schedules is highly dependent on this network; we have no manual back-up. If a portion of this network were to experience a prolonged disruption or
failure in service, our ability to plan factory activity and respond to demand would be impaired.

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

We rely significantly on
patents to protect our intellectual property rights. We have increased investment in intellectual property protection in the last several years and, as of December 29, 2006, we owned more than 1,300 United States patents and 184 foreign
patents. We also have more than 900 patent applications currently pending. Our patents and patent applications may not provide meaningful protection from our competitors as the status of any patent involves complex legal and factual questions, and
the breadth of claims allowed is uncertain. Our competitors may be able to circumvent our patents or develop new patentable technologies that displace our existing products. In addition to patent protection, we rely on trademark, trade secret,
copyright, and mask work laws to protect our unpatented proprietary information or technologies. Despite our efforts to protect our proprietary rights from unauthorized use or disclosure, other parties, including our former employees or consultants,
may attempt to disclose, obtain, or use our proprietary information or technologies without our authorization. If other companies obtain our proprietary information or technologies, or develop substantially equivalent information or technologies,
they may develop products that compete against our products.

Moreover, the laws of certain countries in which our products are or may be
developed, manufactured or sold may not protect our products and intellectual property rights to the same extent as the laws of the United States. Policing the unauthorized use of our products is difficult and may result in significant expense to us
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 not be able to prevent misappropriation of our technology. Use by others of our
proprietary rights could materially harm our business and expensive litigation may be necessary in the future to enforce our intellectual property rights.

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

From time to time in the normal course of business, we receive inquiries from other parties with respect to possible patent infringements. As a result of these inquiries, it may be necessary or desirable for us to
obtain licenses relating to one or more of our current or future products. We may not be able to obtain licenses on reasonable terms. Additionally, license agreements may have set durations and/or have limited license grants and therefore may not
provide complete protection against infringement claims involving all of our current or future products. For example, the settlement agreement that we entered into with Xilinx in July 2001, which prohibited patent litigation between the two
companies, expired in July 2006.

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 also tend to be
unpredictable and may be affected by events outside of our control. If we are unsuccessful in defending against intellectual property infringement claims, 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 expend 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 operation, or cash flows.

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

We produce highly complex products that incorporate leading-edge technology, including both hardware and software. Our pre-shipment testing programs
may not detect all defects, either ones in individual products or ones that could affect numerous shipments. Because we generally warrant our products for varying lengths of time against defects in materials and workmanship and non-conformance to
our specifications, we have on occasion been required to repair or replace certain components or refund the purchase price paid by our customers due to product defects. If there are material increases in customer claims or the costs to service
warranty claims compared with our historical experience, our revenue, gross margins, and net income may be adversely affected. For example, an inability to cure a product defect in a timely manner could result in product reengineering expenses,
increased inventory costs, or damage to our reputation, any of which could materially impact our revenue, gross margins, and net income.

We may be subject to product liability claims.

We sell to customers in the automotive, military, aerospace, avionics,
medical equipment, and other industries where our devices are used in systems that could cause damage to property or persons if those systems were to fail. We may be subject to product liability claims if our devices are the cause of system
failures. Based on our historical experience, we believe that the risk of exposure to product liability claims is currently low. However, we will face increased exposure to product liability claims if there are substantial increases in both the
volume of our sales into these applications and the frequency of system failures caused by our devices.

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 93% of our total sales during 2006. We rely on many distributors to assist us in creating customer
demand, providing technical support and other value-added services to our customers, filling customer orders, and stocking our products. Our contracts with our distributors may be terminated by either party in a relatively short period of time.

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 impact our distributors operations.

We are highly dependent on Arrow Electronics, Inc., in many locations across the world, particularly in North America.

During 2006, Arrow Electronics, Inc. on a worldwide basis accounted for approximately 47% of total sales, while our next largest distributors accounted for approximately 15% and 7% of total sales, respectively. At December 29, 2006,
Arrow accounted for 48% of net accounts receivable, while our next largest distributors accounted for 17%, 13%, and 13% of net accounts receivable, respectively.

Our complex communications infrastructure limits our ability to add or replace distributors or manufacturing subcontractors.

Our distributors and manufacturing subcontractors must have a relatively high level of data processing and communications expertise to link to our global communications network. Even for distributors or manufacturing
subcontractors with sophisticated data processing and communications capabilities, the process of integrating their system with our system over our network can take weeks or months. Thus, there is a long lead time to add new or replace existing
distribution or manufacturing partners.

The length of our design-in and sales cycle could impact our ability to forecast future sales.

Our sales depend on our products being designed into our end customers products and those products achieving volume production.
Our products are very complex in nature, and the time from design-in to volume production ranges from 6 months to 3 years or more. From initial product design-in to volume production, many factors could impact the timing and/or amount of sales
actually realized. These factors include, but are not limited to, changes in the competitive position of our technology, the competitiveness of our customers products in the markets they serve, our customers financial stability, customer
program delays and cancellations, and our ability to ship products according to our customers schedule.

##### Table of Contents

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

We have experienced and continue to experience a decrease in the selling prices of
our products. We have attempted to offset the decrease in selling prices through manufacturing cost reductions, improving our yields, and increasing unit sales. However, there is no guarantee that our ongoing efforts will be successful or that they
will keep pace with the anticipated, continued decline in selling prices of our products, which could ultimately lead to a decline in revenues and have a negative effect on our 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.

During each of the last three years, international sales were a majority of
our total sales. During 2006, international sales constituted approximately 76% of our total sales. We expect that international sales will continue to account for a significant portion of our total 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, generally longer receivable collection periods, and natural or man-made disasters in a specific country or region where we sell our products. Our business is also subject to the
burdens of complying with a variety of foreign laws and risks associated with the imposition of legislation and regulations relating specifically to the importation or exportation of semiconductor products. Quotas, duties, tariffs, taxes, or other
charges, restrictions, or trade barriers may be imposed by the United States or other countries on the import or export of our products in the future.

Our business is subject to tax risks associated with being a multinational corporation.

As a
multinational corporation, we conduct our business in many countries and are subject to taxation in many jurisdictions. The taxation of our business is subject to the application of multiple and sometimes conflicting tax laws and regulations as well
as multinational tax conventions. The application of tax law is subject to legal and factual interpretation, judgment, and uncertainty, and tax laws themselves are subject to change. Consequently, taxing authorities may impose tax assessments or
judgments against us that could result in a significant charge to earnings relating to prior periods and/or an increase in our effective income tax rate.

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

Our gross margins may fluctuate
depending on many factors, including, but not limited to, our product mix, market acceptance of our new products, competitive pricing dynamics, geographic and/or market segment pricing strategies, changes in the mix of our business between
prototyping- and production-based demand, and 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 business books and ships, on sales generated through our distributors within the same quarter, forecasting our gross margins is difficult.

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. During 2000-2001, the semiconductor industry was
significantly impacted by the economic downturn and contraction in the computing and communication equipment markets and by the ensuing inventory correction in the supply chain for those industries. This down cycle, like many of the preceding down
cycles, resulted in significant reductions in unit demand, excess customer inventories, price erosion, and excess production capacity. We experienced five consecutive declines in quarterly sales beginning in the fourth quarter of 2000 and ending in
the fourth quarter of 2001. The protracted deceleration resulted in a peak-to-trough decline in quarterly sales of nearly 60%.

In addition
to reductions in sales, our profitability decreases during downturns as we are unable to reduce our expenses at the same rate as our sales decline. For example, at the height of the previous up cycle, in the third quarter of 2000, our operating
expenses were less than 27% of net sales compared to 50% in the first quarter of 2002. Similarly, our gross margins tend to deteriorate and fluctuate during down cycles. For example, in the third quarter of 2000, our



18

##### Table of Contents

reported gross margin was over 66% of net sales compared to 60% of net sales in the first quarter of 2002. Furthermore, the industry contraction during
2000-2001 was prolonged and severe and resulted in an inventory charge of $154.5 million in 2001 relating primarily to the write-off of inventories in excess of projected demand. Additionally, as a result of reduced demand and in an effort to reduce
our ongoing expense levels, we incurred restructuring charges and write-downs totaling $47.7 million in 2001. In the fiscal year ended December 31, 2000, our net income was $491.7 million on net sales of $1.4 billion whereas for the fiscal year
ended December 31, 2001, we reported a net loss of $46.5 million on net sales of $839.4 million. We expect that our future sales and profitability will continue to be volatile.

In an effort to reduce the possibility of future excess inventory, we reduced our inventory carrying targets in 2002. Reductions in targeted inventory
carrying levels may result in poorer delivery performance relative to our customers desired lead times. Poor delivery performance over time may erode our competitive position and result in a loss of market share. Despite our intent to operate
with lower inventory levels, we are likely to experience inventory write-downs in the future, especially if our inventory becomes out-of-mix with, or excess to, customer demand.

As we carry only limited insurance coverages, 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 resulting from covered incidents.
Additionally, we do not have coverage for certain losses. We have made certain judgments regarding our existing insurance coverage that we believe are 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.

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, 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 enable us 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.

We have been named as a party to several lawsuits related to our historical
stock option practices and related accounting and reporting, and we may be named in additional litigation in the future, all of which could result in an unfavorable outcome and have a material adverse effect on our business, financial condition,
results of operations, cash flows and the trading price for our securities.

Lawsuits are currently pending against certain of our
current and former directors and officers relating to our historical stock option practices and related accounting and reporting. See Part I, Item 3 Legal Proceedings and Note 12 Legal Proceedings for a more detailed
description of these proceedings. Under certain circumstances, we have contractual and other legal obligations to indemnify and to incur legal expenses on behalf of current and former directors and officers in connection with these lawsuits. We may
become the subject of additional private or government actions regarding these matters in the future. These actions are in the preliminary stages, and their ultimate outcome could have a material adverse effect on our business and the trading price
for our securities. Litigation may be time-consuming, expensive and disruptive to normal business operations, and the outcome of litigation is difficult to predict. The defense of these lawsuits may result in significant expenditures and the
continued diversion of our managements time and attention from the operation of our business, which could impede our business.

We
are in the process of implementing a new enterprise resource planning (ERP) system to manage our worldwide financial, accounting and operations reporting.

We have been preparing for the ERP system implementation for over a year and are taking appropriate measures to ensure the successful and timely implementation including but not limited to hiring qualified consultants
and performing extensive testing. However, implementations of this scope have inherent risks that in the extreme could lead to a disruption in our financial, accounting and operations reporting as well as the inability to obtain access to key
financial data.

Our headquarters
facility is located in San Jose, California, on approximately 25 acres of land that we purchased in June 1995. The campus for the headquarters facility currently consists of four interconnected buildings totaling approximately 500,000 square feet.
Design, research, marketing, administrative, and limited manufacturing activities are performed in this facility. In addition, we own approximately 20 acres of land in Santa Clara County, California. We also have a 240,000 square foot design and
test engineering facility in Penang, Malaysia. This facility is situated on land leased on a long-term basis from the Penang Development Corporation. Finally, we lease our domestic and international offices, including our technology centers in the
United Kingdom and Toronto, Canada. Rental expense under all operating leases amounted to approximately $10.6 million in 2006. We believe that our existing facilities and properties held for any planned future expansions are adequate for our current
and foreseeable future needs.



|ITEM3. |  | LEGAL PROCEEDINGS.
|------ |  | ------------------

Litigation

We have been named as a party to several lawsuits 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). A hearing on that motion is currently scheduled for April 20, 2007.

The
consolidated California state court action names Altera Corporation as a nominal defendant and the following current and former Altera officers and directors as defendants: John P. Daane, Nathan M. Sarkisian, Denis M. Berlan, Robert W. Reed,
Robert J. Finocchio, Jr., Kevin McGarity, Paul Newhagen, William E. Terry, Susan Wang, Charles M. Clough, Rodney Smith, Michael B. Jacobs, Katherine E. Schuelke, Deborah Reiman, Michael J. Ellison, C. Wendell Bergere, Clive McCarthy, and Peter
Smyth. Plaintiffs assert claims against these individual defendants for breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate assets, unjust enrichment, violations of California Corporation Code sections 25402 and
25403, breach of fiduciary duty for insider selling and misappropriation of information, rescission, constructive trust, accounting, and deceit. Plaintiffs 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. Plaintiffs seek, among other relief, an indeterminate amount of damages from the individual
defendants and a judgment directing Altera to reform its corporate governance.

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. Altera moved to dismiss this action for lack of standing on January 29, 2007.

Among
the defendants named in these derivative actions are Altera Corporation as a nominal defendant and the following current and former officers and directors of Altera: John P. Daane, Nathan M. Sarkisian, Denis M. Berlan, Robert W. Reed, Robert J.
Finocchio, Jr., Kevin McGarity, Paul Newhagen, William E. Terry, Susan Wang, Charles M. Clough, Rodney Smith, Michael B. Jacobs, Katherine E. Schuelke, John R. Fitzhenry, Deborah Reiman, Michael J. Ellison, C. Wendell Bergere, Clive McCarthy, and
Peter Smyth. The consolidated complaint includes claims for

violations of Sections 10(b), 14(a), and 20(a) of the Securities Exchange Act of 1934, breach of fiduciary duty, corporate waste, gross mismanagement, unjust
enrichment, abuse of control, insider selling and misappropriation of information, rescission, accounting, and violations of California Corporation Code sections 25402 and 25502.5. Plaintiffs claims concern the granting of stock options by
Altera between 1995 and 2001 and the alleged filing of false and misleading financial statements between 1996 and 2005.

Other
Proceedings

In May 2006, after we notified the Securities and Exchange Commission (SEC) that the board of directors had
formed a special committee to review our historical stock option practices and related accounting and reporting, the SEC notified us that it had opened an inquiry relating to this matter. On February 15, 2007, we were notified by the SEC that
its investigation relating to our historical stock option practices and related accounting had been terminated and that no enforcement action had been recommended.

In May 2006, we received a subpoena from the office of the United States Attorney for the Northern District of California (DOJ) requesting information concerning our historical stock option practices and
related accounting. We have cooperated with the DOJ in response to the subpoena and have had no substantive communications with them since October 2006.

|ITEM7. |  | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS.
|------ |  | --------------------------------------------------------------------------------------

Critical Accounting Estimates

The preparation of our consolidated financial statements and related disclosures in
conformity with accounting principles generally accepted in the United States (U.S.) requires our management to make judgments and estimates that affect the amounts reported in our consolidated financial statements and accompanying
notes. Our management believes that we consistently apply these judgments and estimates and the consolidated financial statements and accompanying notes 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; (3) income taxes; and (4) stock-based compensation.

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 more than 90% of our products to distributors for subsequent resale to OEMs or their subcontract manufacturers. In almost all cases, sales to distributors are made under agreements allowing for returns and subsequent price
adjustments, and we defer recognition of revenue 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
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. Because the data set is so large and because there are errors in the reported data,
we must use estimates and apply judgments to reconcile distributors reported inventories to their activities. 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 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. Historically, it has been difficult to forecast customer demand especially at the part-number level. 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 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.

We routinely compare our inventory against projected demand and record provisions for excess and obsolete inventories as
necessary. However, 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.

INCOME TAXES  |  We make certain estimates and judgments in the
calculation of tax liabilities and the determination of net deferred tax assets, which arise from temporary differences between tax and financial statement recognition methods. 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.

In addition, the calculation of our tax
liabilities involves the inherent uncertainty associated with the application of 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



25

##### Table of Contents

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 Provision for Income Taxes and Note 9  Income Taxes for further discussion.

Effective December 30, 2006, the first day of our 2007 fiscal year, we will be required to adopt FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an interpretation of SFAS
109 (FIN 48). In July 2006, the FASB issued FIN 48, which prescribes a comprehensive model for recognizing, measuring, presenting and disclosing in the consolidated financial statements tax positions taken or expected to be taken
on a tax return, including a decision whether to file or not to file in a particular jurisdiction. FIN 48 is effective for fiscal years beginning after December 15, 2006. If there are changes in net assets as a result of application of FIN 48,
they will be accounted for as an adjustment to retained earnings. We are currently assessing the impact of FIN 48 on our consolidated financial position and results of operations. Based on our preliminary analysis, we expect a substantial portion of
our income taxes payable balance of $125.2 million as of December 29, 2006 to be reclassified in 2007 as a non-current liability.

We
calculate our current and deferred tax provision based on estimates and assumptions that could differ from the actual results reflected in income tax returns filed. Adjustments for differences between our tax provisions and tax returns are recorded
when identified, which is generally in the third or fourth quarter of our subsequent year.

STOCK-BASED
COMPENSATION  |  On December 31, 2005, the first day of our 2006 fiscal year, we adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS 123(R))
which requires the measurement and recognition of compensation expense for share-based payment awards. We recognize compensation cost over the requisite service period of share-based awards, usually the vesting period, based on the estimated fair
value of the award. Share-based payment awards for which we currently recognize stock-based compensation expense include stock options, restricted stock units, and employee purchase rights under our 1987 Employee Stock Purchase Plan (ESPP
Shares). The fair value of restricted stock units is based on the fair market value of our stock on the date of grant. To determine the fair value of stock options and ESPP Shares, we use the Black-Scholes pricing model. The fair value of
stock options granted is estimated on the date of grant. The fair value of ESPP Shares is estimated on the first day of the offering period. Using the Black-Scholes pricing model requires us to develop highly subjective assumptions including the
expected term of awards, expected volatility of our stock, expected risk-free interest rate, and expected dividend rate over the term of the award. Our expected term of awards assumption is based primarily on our historical experience with similar
grants. Our expected stock price volatility assumption for both stock options and ESPP Shares 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. The selection of a combination of implied and historical volatility was based upon the availability of actively traded options on our stock and also upon our assessment that a combined volatility is more representative of future
stock price trends than historical volatility. The risk-free interest rate assumption approximates the risk-free interest rate of a zero-coupon Treasury bond with a maturity approximately equal to the expected term of the stock option or ESPP
Shares. In addition to the assumptions used in the Black-Scholes pricing model, SFAS 123(R) requires that we recognize expense for awards ultimately expected to vest; therefore we are required to develop an estimate of the number of awards expected
to cancel prior to vesting (forfeiture rate). The forfeiture rate is estimated based on historical pre-vest cancellation experience and is applied to all share-based awards. We monitor the assumptions used to compute the fair value of
our share-based awards and we will revise our assumptions as appropriate. In the event that assumptions used to compute the fair value of our share-based awards are later determined to be inaccurate or if we change our assumptions significantly in
future periods, stock-based compensation expense and our results of operations could be materially impacted. See Note 8  Stock-based compensation to our consolidated financial statements for further information regarding the
valuation of stock-based compensation.

Executive Overview

Company and Market Overview

We
are a global semiconductor company, serving over 14,000 customers in communications, computer and storage, industrial, and consumer market segments. We design, manufacture, and market: (1) programmable logic devices, or PLDs; (2) HardCopy
structured application-specific integrated circuit, or ASIC, devices; (3) pre-defined design building blocks known as intellectual property, or IP cores; and (4) associated development tools.



26



---

##### Table of Contents

PLDs are semiconductor integrated circuits that are built as standard chips that customers program to
perform desired logic functions within their electronic systems. Our PLDs consist of field-programmable gate arrays, or FPGAs, and complex programmable logic devices, or CPLDs. Approximately 90% of our revenue is generated from the sales of our
PLDs. The majority of the remainder of our revenue is derived from (1) the sale of our HardCopy devices, which enable our customers to move from a high-density FPGA to a low-cost, high-volume non-programmable implementation of their designs,
and (2) the licensing of IP cores and proprietary development tools. Our IP cores enable customers to easily implement standard functions in their PLD designs, and our development tools are necessary to program our PLDs.

Market Opportunity

We believe
that the greatest opportunity for our growth is displacing ASICs and application-specific standard products (ASSPs). We estimate based on publicly available data, and with information derived from Gartner Dataquest, that the PLD market
was approximately $3.7 billion in 2006, whereas the digital logic market, consisting primarily of ASICs and ASSPs, amounted to approximately $35 billion. Because PLDs can be quickly programmed by the customer to perform the specific function the
customer desires, we believe that PLDs provide greater advantages in flexibility, development cost, and time-to-market over ASIC and ASSP alternatives. However, PLDs generally have a higher cost structure than these alternatives. Thus PLDs are
particularly favored in applications where there is a substantial premium afforded to time-to-market and in end-applications where unit volumes are low. Because of the relatively higher cost of PLDs, customers often use PLDs for their system
development and prototyping and then use ASIC technology in volume production. Nevertheless, we believe that (1) advances in PLD technology and in semiconductor manufacturing technology in general are lowering the relative cost differential
between PLDs and fixed chip alternatives, (2) we have been and can continue to be increasingly successful in selling PLDs into applications and markets that have been traditionally served by ASICs and ASSPs, and (3) we can compete
successfully for customers volume production needs as well as their initial prototyping and development needs.

The PLD market peaked
at approximately $4.1 billion in 2000 and declined over the next two years to approximately $2.3 billion in 2002. From 2002 to 2006, the PLD market has grown each year, with a compound average growth rate of approximately 13%. Due to the broad
customer base for PLD vendors, and the diverse market segments that they serve, future growth rates for the PLD market are difficult to forecast and they may be lower than recent years. PLD market growth will be driven by the rate at which PLD
vendors can grow their customer base in both prototyping and production opportunities. The two leading PLD vendors serve an extremely large and diverse customer base and the opportunity to expand the number of customers may be limited. As a result,
a critical objective for PLD vendors is not simply to add more prototyping customers, but rather to penetrate customers and end markets in high volume applications. The PLD vendors ability to access higher levels of production volume is
contingent upon several factors including their ability to offer cost-effective solutions versus ASIC and ASSP products. Publicly available data suggests that the number of ASIC design starts is in decline and the amount of PLD logic consumed is
growing rapidly. At the same time, the price per effective unit of logic of PLDs has declined at a rate that partially offsets the increase in the amount of PLD logic consumed. In the future, as PLD vendors seek penetration into high volume
applications by offering lower cost devices, we expect the price per effective unit of logic to continue to decrease and partially offset revenue increases driven by higher PLD logic consumption.

Competing for Design Wins

We
compete with other PLD vendors to displace fixed chip logic alternatives and for market share within the PLD market. The programmable logic market is highly concentrated with two vendors accounting for a majority of the total market: ourselves and
Xilinx, Inc. Competition between PLD vendors is most intense in the design-win phase of the customers design. A design win occurs when a customer selects a particular vendor product for use in the customers electronic system.
Because each PLD vendors product offering is proprietary, the cost to switch PLD devices 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 as long as two years, and sometimes longer,
before a customer starts the volume production of its system. Typically, a PLD vendor for a particular application is selected relatively early in a customers design program. It may take several years from that point before the customer has
completed its entire

system design, built prototypes, sampled the marketplace for customer acceptance, made any modifications, and established volume manufacturing capacity.
Thus, movements in PLD market share often occur some time after the change in relative competitiveness that gave rise to the market share shift. Because of this time lag, market share is a lagging indicator of relative competitive strength. Because
it is extremely difficult to forecast the degree of success and timing of customers programs, and because the end markets are so fragmented (we have over 14,000 PLD customers), it is difficult even for PLD vendors to gauge their own
competitive strength in securing design wins as of 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 the PLD
vendors products, particularly the effectiveness and reliability of a PLD vendors proprietary development software. All PLD vendors provide proprietary development software at little or no cost to the customer. The 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, there is often an increasing likelihood that the customer will 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 device development, 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 in using our software.

We focus our research and development resources on new generation FPGA devices because increasing market
share in the FPGA sub-segment is important to our long-term growth and profitability. Due to the higher integration density and lower cost per function, the FPGA sub-segment has outgrown the CPLD sub-segment in recent times, and it is generally
accepted by participants and observers of the industry that this trend will continue. In 2002, we introduced two new FPGAs: the Stratix high-end and the Cyclone low-cost families. In 2003, we introduced a transceiver-based Stratix GX family. In
2004, we introduced the next generation high-end FPGA, the Stratix II family, and, in early 2005, the new low-cost Cyclone II family. In 2006, we announced the next generation Stratix III family, which is planned for shipment beginning in 2007. As a
result of these product introductions, we estimate based on publicly available data, and with information derived from Gartner Dataquest, that our FPGA market share versus our main competitor has increased from 31 percent in 2002 to 36 percent in
2006. Our current overall PLD market share is 35 percent.

Adding to our Stratix FPGAs is our HardCopy family of structured ASICs. We first
shipped HardCopy devices in 2001, offering to our customers low-cost, non-programmable production devices that use our highest density FPGAs as an integrated development vehicle. The conversion from the FPGA is virtually seamless and requires very
little additional customer engineering. This product is targeted specifically at those applications and customers that have used PLDs for prototyping and development and ASICs from other vendors for their volume production needs. In 2006, our
HardCopy device revenues were less than 5 percent of total revenues and we believe HardCopy may increase as a percentage of revenues over the long term.

The presence of a HardCopy conversion path for high-density designs differentiates our FPGA offering competitively. Since 2001, we have introduced newer versions of the HardCopy family to support newer generations of
FPGAs. Our approach is unique in the industry and may under perform our expectations. There are other structured ASIC competitors who are larger in size than we are and who have established reputations as ASIC suppliers; currently we provide
customers with an automated conversion from an FPGA to a structured ASIC. As we develop new generations of FPGAs, we may create parallel HardCopy devices, which entails ongoing engineering effort and expense.

In 2004, we improved our CPLD offering with the introduction of the MAX II family. The MAX II family offers price and features that we believe are
competitively attractive, with economics, performance, and density that are superior to our previous offerings. Since the unit price of these devices is low compared to our other new products, we will need to ship substantial unit quantities to
increase market share in the CPLD market.

An FPGA family typically reaches peak sales 4 to 5 years after product introduction. As a result,
the original Stratix and Cyclone families we introduced in 2002, which comprised approximately 30 percent of total sales in 2006, may be at or near peak sales. The products we introduced from 2003 to 2006 have yet to reach peak sales, but will
eventually experience sales declines. For us to improve or even sustain our rate of growth, we must successfully introduce successor generations of devices. To the degree other PLD vendors have improved or will improve the competitiveness

and execution of their products, our ability to improve our rate of growth may be impaired. Within the next several quarters, we plan to ship newer families
of FPGA devices 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 processes. 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 will 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
current market share success. Our main competitor is larger in size with more sales resources, and we may not enjoy the same success that we saw with previous FPGA generations.

Customer Intimacy and Cost-Optimized Product Strategy

In general, we rely on interaction with our customers to gain product development insights, and we make development decisions years before a product begins to ship. We have been able to gain market share on the
strength of our product definition methodology and the successful rollout of new products. However, because our products are complex, we assume considerable risk with every new product introduction. If we misinterpret customer requirements or
changes in demand, our products may become uncompetitive. Our competitors are knowledgeable and skilled and, in some cases, larger than we are. Since it is difficult to gauge competitive success until the design-win phase is well underway, it may be
too late to make any changes to a generation of products if those products are uncompetitive. If a generation of our products is uncompetitive and we lose market share, regaining customers subsequently is very challenging.

Since 2002 and following the semiconductor industry correction, our strategy to displace ASICs and ASSPs has emphasized the development of cost-optimized
products. These products have contributed to growth across all of our market segments and are increasingly being used by our customers in production volumes, not just as prototyping or low-volume solutions. Production volumes vary by industry, but
customers buying our products for use in production volumes expect lower unit pricing. Consequently, our business today is subject to a wider range of gross margins than the range of gross margins associated with a less diverse, largely prototyping
business. Depending on the mix of high- and low-volume business, our gross margins can vary more quarter to quarter than in the past. Since the majority of our business books and ships in the same quarter, forecasting our gross margins has also
become more difficult. While we believe that growth will occur across all of our market segments, our gross margins could move upward or downward if our growth pattern favors a low-volume or high-volume market segment.

In January 2006, we changed
our product categories (New, Mainstream and Mature and Other Products). All prior period data has been adjusted to conform to the current classification.

Sales Overview

Net sales were $1.29 billion in 2006, $1.12 billion in 2005, and $1.02 billion in
2004. Net sales increased 14% in 2006 from 2005, and 11% in 2005 from 2004.

The increase in net sales in 2006 was driven by sales of our
New Products which increased 150% year-over-year predominantly due to higher sales of our Stratix II and Cyclone II families. Our 2006 sales reflected higher unit sales of New and Mainstream Products, with New Product unit sales increasing the most.

The increase in net sales in 2005 was driven primarily by the sales of our New and Mainstream Products for the composition of our product
categories) which increased 433% and 47% year-over-year respectively predominately due to higher sales of our Stratix, Stratix II, Cyclone, and Cyclone II families. Stratix was our largest selling family in 2005. Our 2005 sales reflected higher unit
sales of all product categories, with Mainstream unit sales increasing the most.

No single end customer provided more than 10% of our total
sales for any of the fiscal years ended 2006, 2005, or 2004.

During 2006, the Communications, Industrial and Computer and Storage market segments grew as a
result of increased customer demand and penetration into new applications. We expect the Communications market segment will remain our largest as a percentage of our total sales.

During 2005, the Communications and Consumer market segments grew as a result of increased customer demand, penetration into new applications, and market
share gains.

Excluding the gross margin benefit from the sale of inventory written down in 2001, gross margin
remained flat in 2006 compared to 2005. Gross margin net of the gross margin benefit from the sale of inventory written down in 2001 decreased 1.8 percentage points in 2005 from 2004. The decrease was primarily due to reduced demand in certain
high-margin programs and increasing success in securing high-volume design wins with discounted prices.

In 2001, we recorded total
inventory provisions of $154.5 million as a result of unfavorable economic conditions and diminished demand for semiconductor products. As of December 29, 2006, substantially all of the inventory that was written-down in 2001 had been either
sold or scrapped. As of December 29, 2006, the book value of the inventory written down in 2001 was zero while the cost basis was $2.4 million, which was comprised only of raw materials and work in process inventory.

Stock-based compensation expense recognized in 2006 had an immaterial impact on our gross margin.

Research and development expenses include expenditures for labor and benefits, masks, prototype
wafers, and depreciation. These expenditures were for the design of new PLD and structured ASIC families, and the development of process technologies, new packages, software to support new products and design environments, and IP cores. Also
included in research and development expenses is the mark-to-market impact of the Altera Non-Qualified Deferred Compensation Plan (NQDC Plan) of $2.6 million in 2006, $1.1 million in 2005, and $1.0 million in 2004.

Research and development expenses increased $38.9 million in 2006 compared to 2005 primarily due to increased stock-based compensation expense resulting
from our adoption of SFAS 123(R) effective December 31, 2005. The stock-based compensation expense classified as research and development expense was $28.6 million in 2006, compared to zero in 2005. Research and development expenses also
increased year-over-year due to higher spending on labor and benefit costs due to increased headcount.

Research and development expenses
increased $27.9 million in 2005 compared to 2004. The increase in spending was primarily due to higher spending on prototype wafers for next generation products, and higher spending on labor and benefit costs due to increased headcount. Also

##### Table of Contents

Historically, the level of our research and development expenses has fluctuated in part due to the timing
of the purchase of masks and prototype wafers used in the development of new products. 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 utilize advanced semiconductor wafer fabrication processes, as well as related development software. We are currently investing in the development of our Stratix III, Stratix II GX, and HardCopy II families, our Nios II soft core embedded
processor, our Quartus II software, our library of IP cores, and other future products.

Selling, general, and administrative expenses primarily include labor and benefit expenses related
to sales, marketing, and administrative personnel, commissions and incentives, depreciation, legal, advertising, facilities, and travel expenses. Also included in selling, general, and administrative expenses is the mark-to-market impact of our NQDC
Plan of $3.2 million in 2006, $1.3 million in 2005, and $1.7 million in 2004.

Selling, general, and administrative expenses increased by
$81.9 million in 2006 compared to 2005. The increase was primarily due to an increase in stock-based compensation expense resulting from our adoption of SFAS 123(R) effective December 31, 2005. The stock-based compensation expense classified as
selling, general, and administrative expense was $37.7 million in 2006, compared to $0.3 million in 2005. Selling, general and administrative expenses increased year-over-year also due to higher labor and benefit costs as we added sales and
marketing personnel to drive our revenue growth, higher consulting expenses relating to the implementation of a new enterprise resource planning (ERP) system, and higher professional fees of approximately $10.1 million associated with our stock
option investigation, financial statement restatement, and related litigation.

Selling, general, and administrative expenses increased by

Interest and other income, net consists mainly of interest income generated from investments in
high-quality fixed tax exempt and taxable income securities, as well as the mark-to-market impact of our NQDC Plan.

Interest and other
income, net increased by 68% in 2006 compared to 2005 primarily as a result of higher investment yields and higher cash and investment balances.

Interest and other income, net increased by 87% in 2005 compared to 2004 primarily as a result of higher investment yields.

PROVISION FOR INCOME TAXES  |  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 10% for 2006, 22% for 2005, and 17% for 2004. The decrease in our effective tax rate in 2006 compared to 2005 was due to an increase in tax-exempt income as a percentage of total income, resolution of tax audits, and a
favorable

change in the geographical mix of income, as well as the impact of accounting for stock-based compensation in accordance with SFAS 123(R) where the majority
of our stock-based compensation expense relates to U.S. based employees. Our 2005 effective tax rate also included an additional income tax provision related to the repatriation of foreign earnings under the American Jobs Creation Act of 2004
(AJCA), partially offset by an income tax benefit from the settlement of federal and California income tax audits.

LIQUIDITY  |  We derive our liquidity and capital resources primarily
from our cash flows from operations. We continue to generate positive operating cash flows. We currently use cash generated from operations for capital expenditures, investments and repurchases of our common stock. Based on past performance and
current expectations, we believe our current available sources of funds including cash, cash equivalents, and investments, plus the anticipated cash generated from operations, will be adequate to finance our operations and capital expenditures for
at least the next year.

YEAR 2006  |  In 2006, we spent $140.4 million to repurchase our common stock, compared
to $369.9 million in 2005. The decrease was due to the temporary suspension of our stock repurchase program during May to October 2006 which was necessitated by our failure to timely file our periodic reports as a result of the restatement of our
consolidated financial statements in connection with our internal stock option investigation. We also spent $36.5 million on capital expenditures in 2006, compared to $25.9 million in 2005. The increase was due primarily to the implementation of a
new ERP system. As of the date of this filing, we have spent approximately $24 million on the ERP project and total planned expenditures are estimated to be $35 million. We expect to install and have the ERP system operational in 2007. In 2007, we
also plan to continue to use a portion of our available capital to repurchase shares of our common stock.

CASH
FLOWS  |  Our positive cash flows from operating activities for the fiscal year ended December 29, 2006 were primarily attributable to net income of $323.2 million, adjusted for non-cash items including stock-based
compensation expense of $68.1 million, depreciation and amortization of $29.7 million, and cash inflows of $16.5 million from changes in our working capital, excluding cash. Non-cash working capital changes primarily included a $39.8 million
increase in deferred income and allowances on sales to distributors as a result of increased shipments into the channel, offset by a $7.8 million increase in inventories and $17.0 million increase in other assets.

Cash used for investing activities for the fiscal year ended December 29, 2006 primarily consisted of purchases of available-for-sale investments,
net of proceeds from the maturities and sales of available-for-sale investments, of $385.8 million, and capital expenditures of $36.5 million.

Cash used for financing activities for the fiscal year ended December 29, 2006 consisted of repurchases of common stock of $140.4 million, which was partially offset by net proceeds of $80.9 million from the issuance of common stock to
employees through our stock option and employee stock purchase plans.

YEAR 2005  |  In 2005, we spent $369.9
million to repurchase our common stock, compared to $176.3 million in 2004. We also spent $25.9 million on capital expenditures in 2005, compared to $24.7 million in 2004.

CASH FLOWS  |  Our positive cash flows from operating activities for the
fiscal year ended December 30, 2005 were primarily attributable to net income and cash inflows of $65.6 million resulting from year-over-year changes in working capital, excluding cash. These changes included an increase in accounts receivable
of $13.0 million, a decrease in other current assets primarily due to the collection in 2005 of a $17 million income tax refund related to the filing of our 2004 federal income tax return, a $37.2 million increase in deferred income and allowances
on sales to distributors due to an increase in inventory held by distributors, and a $25.1 million increase in income taxes payable resulting primarily from the accrual for income taxes to be paid as a result of the repatriation of unremitted
foreign earnings under the AJCA (see Note 9  Income Taxes to our consolidated financial statements).

Cash provided by
investing activities for the fiscal year ended December 30, 2005 primarily consisted of proceeds from the maturities and sales of investments, net of purchases, of $128.4 million, partially offset by capital expenditures of $25.9 million.

Cash used for financing activities for the fiscal year ended December 30, 2005 consisted of repurchases of common stock of $369.9
million, which was partially offset by net proceeds of $57.8 million from the issuance of common stock to employees through our stock option and employee stock purchase plans.

CONTRACTUAL OBLIGATIONS  |  The following table summarizes our significant contractual cash obligations at December 29,
2006, and the effect that such obligations are expected to have on liquidity and cash flows in future periods:

| | (1) |  | We lease facilities under non-cancelable lease agreements expiring at various times through 2011. Rental expense under all operating leases amounted to $10.6 million in 2006, $9.3
million in 2005, and $9.1 million in 2004.
| | --- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) |  | We depend entirely upon subcontractors to manufacture our silicon wafers. Due to lengthy subcontractor lead times, we must order materials 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 2007.
| | --- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (3) |  | We sponsor a retiree medical plan providing medical benefits to eligible retirees and their spouses. Benefits are available to employees hired on or before July 1, 2002 who
retire from Altera at or after age 55 if they have at least 10 years of service. Effective January 1, 2005, future participation is also limited to existing employees who were age 40 or older as of January 1, 2005.
| | --- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition to these leases and purchase 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 material to our financial condition or results of operations.

IMPACT OF CURRENCY TRANSLATION AND INFLATION  |  We purchase the majority of our materials and services in U.S.
dollars and sell our products to OEMs and distributors in U.S. dollars. As of December 29, 2006, we had no open forward contracts; however, we may enter into contracts from time to time to hedge foreign exchange exposure. We have, in the past,
entered into forward contracts to hedge against currency fluctuations associated with contractual commitments denominated in foreign currencies.

COMMON STOCK REPURCHASES  |  Since the inception of our stock repurchase program in 1996 through December 29, 2006, our board of directors has authorized 108 million shares for repurchase and we have
repurchased a total of 93.7 million shares of our common stock for an aggregate cost of $2.0 billion. All shares were retired upon acquisition. On December 29, 2006, 14.3 million shares remained authorized for repurchases under our
stock repurchase program.

|Average price per share                 |  | $    | 19.89 |      | $ | 18.59 |  | $ | 21.36

We temporarily suspended our stock repurchase program from May to October 2006, which was
necessitated by our failure to timely file our periodic reports as a result of the restatement of our consolidated financial statements. During 2006, we entered into agreements pursuant to SEC Rule 10b5-1 under which we authorized a third-party
broker to purchase shares on our behalf during our normal blackout period according to predetermined trading instructions. In addition, we have repurchased shares of our common stock under the guidelines of SEC Rule 10b-18.

OFF-BALANCE SHEET ARRANGEMENTS  |  We do not have any financial partnerships with unconsolidated entities, such as entities
often referred to as structured finance or special purpose entities.

NEW ACCOUNTING PRONOUNCEMENTS  |  In July
2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an interpretation of SFAS 109 (FIN 48). FIN 48 prescribes a comprehensive model for recognizing, measuring, presenting
and disclosing in the financial statements tax positions taken or expected to be taken on a tax return, including a decision whether to file or not to file in a particular jurisdiction. FIN 48 is effective for fiscal years beginning after
December 15, 2006. If there are changes in net assets as a result of application of FIN 48 these will be accounted for as an adjustment to retained earnings. We are currently assessing the impact of FIN 48 on our consolidated financial position
and results of operations. Based on our preliminary analysis, we expect a substantial portion of our income taxes payable balance of $125.2 million as of December 29, 2006 to be reclassified in 2007 as a non-current liability.

On September 13, 2006, the SEC issued Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when
Quantifying Misstatements in Current Year Financial Statements, (SAB 108), which provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a
current year misstatement. The guidance is applicable for our fiscal year 2006. The adoption of SAB 108 did not have an impact on our consolidated financial position and results of operations.

In September 2006, the FASB issued SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans  an
amendment of FASB Statements No. 87, 88, 106, and 132(R) (SFAS 158). SFAS 158 requires an employer to recognize the over-funded or under-funded status of a defined benefit postretirement plan (other than a multiemployer plan)
as an asset or liability in its statement of financial position to recognize changes in that funded status in the year in which the changes occur through comprehensive income of a business entity or changes in unrestricted net assets of a
not-for-profit organization. The provisions of SFAS 158 require an employer with publicly traded equity securities to recognize the funded status of a defined benefit postretirement plan and to provide the required disclosures as of the end of the
fiscal year ending after December 15, 2006. The adoption of SFAS 158 did not have an impact on our consolidated results of operations and the incremental effect on our consolidated balance sheet as at December 29, 2006 is summarized in
Note 11- Employee Benefits Plans.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157,
Fair Value Measurements (SFAS 157). SFAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements. The changes to current practice resulting from the application of SFAS 157
relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. We do not believe that the adoption of the provisions of SFAS 157 will materially impact our consolidated financial position or results of operations.

|ITEM7A. |  | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
|------- |  | -----------------------------------------------------------

INVESTMENT AND INTEREST RATE RISK  |  The primary objective of our investment activities is to
preserve principal while at the same time maximizing yields without significantly increasing risk. We maintain investment portfolio holdings of various issuers, types and maturity dates totaling $1.6 billion as of December 29, 2006. 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 net income is dependent on, among other factors, interest income and realized gains from the sale of marketable securities. If interest rates
decline or we are unable to realize gains from the sale of marketable securities, our net income may be negatively impacted.

FOREIGN
CURRENCY RISK  |  Although we purchase the majority of our materials and services in U.S. dollars and sell our products to OEMs and distributors in U.S. dollars, we do have international operations and are, therefore, subject
to foreign currency rate exposure. To date, our exposure to exchange rate volatility has been insignificant. If foreign currency rates were to fluctuate by 10% from rates at December 29, 2006, our consolidated financial position, results of
operations and cash flows would not be materially affected. However, we cannot guarantee that there will not be a material impact in the future.

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 structured ASIC devices, pre-defined design building blocks known as intellectual property, or 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 communications, computer and storage, consumer, and industrial market segments.

Note 2:    Significant Accounting Policies

BASIS OF PRESENTATION  |  Our fiscal year ends on the Friday nearest December 31st. Our most recent fiscal year ended on December 29, 2006. 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 from
those estimates, and material effects on our operating results and financial position may result.

RECLASSIFICATIONS  |  We have made certain consolidated balance sheet reclassifications to prior period balances in order to conform to the current periods presentation. During 2006, we adopted Statement of
Financial Accounting Standards No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans  an amendment of FASB Statements No. 87, 88, 106, and 132(R) (SFAS 158), and changed the
classification of current deferred income tax assets to non-current deferred income taxes to conform to the classification of the related non-current liability. In addition, to correctly classify the deferred income tax asset-related to our
Non-Qualified Deferred Compensation Plan (NQDC Plan), we changed the classification of certain non-current deferred tax assets to current deferred tax assets as of December 30, 2005. The net impact of the change in classification is
an increase of $16.4 million in current deferred income tax assets on the December 30, 2005 consolidated balance sheet.

The above
reclassifications had no impact on our consolidated statements of income or statements of cash flows for any year presented.

CASH
EQUIVALENTS AND INVESTMENTS  |  Cash equivalents consist of highly liquid investments with original maturities of three months or less.

Management determines the appropriate classification of investments at the time of purchase. As of December 29, 2006, all investments in our portfolio were classified as available-for-sale. Available-for-sale
investments are carried at their fair value based on quoted market prices as of the balance sheet date. Realized gains or losses are determined on the specific identification method and are reflected in Interest and other income, net in our
consolidated statements of income. Net unrealized gains or losses are recorded directly in stockholders equity. Those unrealized losses that are deemed to be other than temporary are reflected in Interest and other income, net.

Effective July 1, 2005, we began to classify certain investments as long-term. Investments classified as Long-term investments represent funds
that are deemed to be in excess of our estimated operating requirements and have remaining maturities exceeding 12 months as of the balance sheet date.

INVENTORIES  |  Inventories are recorded at the lower of cost determined on a
first-in-first-out basis (approximated by standard cost) or market. Inventories at December 29, 2006 and December 30, 2005 were comprised of the following:



|                                  |  |                   |        |                   |   |

In 2001, we recorded total inventory provisions of $154.5 million as a result of unfavorable
economic conditions and diminished demand for semiconductor products. As of December 29, 2006, substantially all of the inventory that was written-down in 2001 had been either sold or scrapped. As of December 29, 2006, the book value of
the inventory written down in 2001 was zero while the cost basis was $2.4 million which was entirely comprised of raw materials and work in process inventory. During the years ended December 29, 2006, December 30, 2005, and
December 31, 2004, we realized gross margin benefits of $2.0 million, $11.1 million, and $14.7 million, respectively, resulting from the sale of inventory previously written down in 2001.

PROPERTY AND EQUIPMENT  |  Property and equipment, net at December 29, 2006 and December 30, 2005 was comprised of
the following:

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 five years are used for equipment and office furniture, up to forty years for buildings and sixty years for land rights. Depreciation
expense includes the amortization of assets recorded under capital leases. 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.
Depreciation expense was $28.3 million in 2006, $27.0 million in 2005, and $26.0 million in 2004.

Assets acquired under capital leases
totaled $8.2 million (net of accumulated amortization of $5.0 million) as of December 29, 2006 and totaled $8.1 million (net of accumulated amortization of $0.9 million) as of December 30, 2005.

We evaluate the recoverability of our property, equipment, and intangible assets on at least an annual basis in accordance with Statement of Financial
Accounting Standards No. 144, or SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, and record an impairment charge against income as appropriate.

FAIR VALUE OF FINANCIAL INSTRUMENTS  |  For certain of our financial instruments, including cash and cash equivalents,
short-term and long-term investments, accounts receivable, accounts payable, and accrued liabilities, the carrying value approximate fair value due to their short maturities.

CONCENTRATIONS OF CREDIT RISK  |  Financial instruments that potentially subject us to concentrations of credit risk consist
principally of cash, cash equivalents, short-term and long-term investments, and accounts receivable. We place our cash, cash equivalents, and short-term and long-term investments 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 and perform on-going credit evaluations of their financial condition and require credit guarantees whenever deemed necessary.

Trade accounts receivable are recorded at the invoiced amount. We maintain allowances for doubtful accounts to reduce our receivables to their estimated net realizable value. The allowance for doubtful accounts balance was $5.0 million
at December 29, 2006 and at December 30, 2005, and is our best estimate of the amount of probable credit losses in our existing accounts receivable. 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. Delinquent account balances are subject to interest charges.
Account balances are charged off against the allowance when it is probable the receivable will not be recovered. We wrote off $102,000 in 2006 and $2,000 in both 2005 and 2004 against our allowances for doubtful accounts and sales returns. Charges
to expense were immaterial for all three years.

Total sales are the sum of our own direct sales to OEMs and our distributors resales
of Altera products. For the fiscal year ended December 29, 2006, worldwide sales through distributors for subsequent resale to OEMs or their subcontract manufacturers accounted for 93% of total sales. Arrow Electronics, Inc., or Arrow,
continues to be our largest distributor. Arrow on a worldwide basis accounted for 47% of total sales in 2006, 44% in 2005, and 46% in 2004. Our second largest distributor, Altima Corporation, accounted for 15% of total sales in 2006, 17% in 2005,
and 16% in 2004. No other distributor accounted for greater than 10% of total sales in 2006 or 2005. In 2004, a third distributor, Paltek Corporation, accounted for 10% of total sales. In March 2006, we terminated our distribution relationship with
Paltek Corporation. For each of the three years ended December 29, 2006, no single end customer accounted for more than 10% of our total sales.

At December 29, 2006, four distributors comprised greater than 10% of Accounts receivable, net, accounting for 48%, 17%, 13%, and 13%, respectively. At December 30, 2005, four distributors comprised greater than 10% of Accounts
receivable, net, accounting for 40%, 19%, 13%, and 11%, respectively.

Distributor advances, included in Deferred income and allowances on
sales to distributors on our consolidated balance sheets, totaled $112.0 million at December 29, 2006 and $74.2 million at December 30, 2005. On sales to distributors, our payment terms generally require the distributor to settle amounts
owed 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. 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. We process discounts taken by distributors against our deferred income and allowances on sales to distributors balance and true-up the advanced amounts generally at the end of
each month. The terms of 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 are, in substance, an arrangement to finance distributors accounts receivable and inventory. The
amounts advanced are settled in cash at least on a quarterly basis and are classified as Other current assets in our consolidated balance sheets and totaled $54.3 million at December 29, 2006 and $34.6 million at December 30, 2005. These
arrangements are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand.

REVENUE RECOGNITION  |  We recognize revenue on products sold to OEMs 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



45



---

##### Table of Contents

our sales on a net basis, excluded from revenues. We record reserves for OEM sales returns and allowances, included in Accounts receivable, net in the asset
section of our accompanying consolidated balance sheets, for any specific known customer returns or allowances. The OEM returns allowance was $9,000 at December 29, 2006 and $44,000 at December 30, 2005. Charges against revenue and claims
processed totaled $1.2 million, $1.1 million, and $0.8 million for the years ended 2006, 2005, and 2004, respectively.

In almost all cases,
sales to distributors are made under agreements allowing for product returns and subsequent price adjustments 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 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, we relieve inventory for the carrying value
of goods shipped since legal title has passed to the distributor, and we 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 each item in our product catalog to all of our distributors worldwide at a uniform list price. However, distributors resell
our products to end customers at a very broad range of individually negotiated price points based on customer, product, quantity, geography, competitive pricing, and other factors. The majority of our distributors resales are priced at a
discount from list price. Often, under these circumstances, we remit back to the distributor a portion of their original purchase price after the resale transaction is completed. Thus, a substantial portion of the 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 the Deferred income and allowances on sales to distributors that will be remitted back to the distributors. Therefore, we do not reduce deferred income 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. These allowances for price concessions
have historically been greater than 60 percent of the deferred income and allowances on sales to distributors account balance.

Revenue from
software and IP licenses is deferred and recognized as revenue over the term of the license subscription, which is generally one year. Revenue from HardCopy non-recurring engineering costs, or NRE, is generally recognized at the conclusion of the
project including customer acceptance.

INCOME TAXES  |  Our provision for income taxes is based on the asset and
liability method prescribed by Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109). Accordingly, our provision for income taxes is based on pre-tax financial accounting income.
This approach recognizes the amount of taxes payable or refundable for the current year, accruals for tax contingencies, as well as deferred tax assets and liabilities for the future tax consequences of events recognized in the consolidated
financial statements and tax returns.

DEPENDENCE ON WAFER SUPPLIERS AND OTHER INDEPENDENT SUBCONTRACTORS  |  We
depend entirely upon independent wafer foundries to manufacture our silicon wafers. We also depend on these wafer foundries 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 our foundry suppliers. 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.

STOCK-BASED COMPENSATION
PLANS  |  On December 31, 2005, we adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS 123(R)), which requires the measurement and
recognition of compensation expense for all share-based awards made to employees and directors, including employee non-qualified and incentive stock options, restricted stock units and employee purchase rights under our Employee Stock Purchase Plan
(ESPP Shares) based on estimated fair values. SFAS 123(R) supersedes previous accounting under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25) for periods
beginning in fiscal year 2006. In March 2005, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin No. 107 (SAB 107) providing supplemental implementation guidance for SFAS 123(R). We have
applied the provisions of SAB 107 in our adoption of SFAS 123(R).

SFAS 123(R) requires companies to estimate the fair value of share-based
awards on the date of grant using an option pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in our consolidated statements of income. We adopted
SFAS 123(R) using the modified prospective transition method which requires the application of the accounting standard starting from December 31, 2005, the first day of our fiscal year 2006. Our consolidated financial statements, as of and for
the year ended December 29, 2006, reflect the impact of SFAS 123(R). In accordance with the modified prospective transition method we used in adopting SFAS 123(R), our results of operations prior to fiscal year 2006 have not been restated to
reflect, and do not include, the impact of SFAS 123(R).

Prior to the adoption of SFAS 123(R), we accounted for share-based awards to
employees and directors using the intrinsic value method in accordance with APB 25 as allowed under Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (SFAS 123). Under APB 25,
compensation cost was measured as the excess, if any, of the quoted market price of our stock at the date of grant over the exercise price of the stock option granted. Under APB 25, compensation cost for stock options, if any, was recognized over
the vesting period using the straight-line single option method.

Stock-based compensation expense recognized in the year ended
December 29, 2006, included stock-based compensation expense for share-based awards granted prior to, but not yet vested as of December 30, 2005, based on the fair value on the grant date estimated in accordance with the pro forma
provisions of SFAS 123, and stock-based compensation expense for the share-based awards granted subsequent to December 30, 2005, based on the fair value on the grant date estimated in accordance with the provisions of SFAS 123(R). In
conjunction with the adoption of SFAS 123(R), we changed our method of attributing the value of stock-based compensation expense from the accelerated multiple-option method (for the purposes of non-GAAP information under SFAS 123) to the
straight-line single option method. Stock-based compensation expense for all share-based awards granted on or prior to December 30, 2005 will continue to be recognized using the accelerated multiple-option approach, while stock-based
compensation expense for all share-based awards granted subsequent to December 30, 2005 will be recognized using the straight-line single option method. SFAS 123(R) requires that we recognize expense for awards ultimately expected to vest;
therefore we are required to develop an estimate of the number of awards expected to cancel prior to vesting (forfeiture rate). The forfeiture rate is estimated based on historical pre-vest cancellation experience and is applied to all
share-based awards. SFAS 123(R) requires the forfeiture rate to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Prior to fiscal year 2006, we accounted for
forfeitures as they occurred.

Upon adoption of SFAS 123(R), we selected the Black-Scholes option pricing model as the most appropriate
method for determining the estimated fair value for stock options and ESPP Shares. The Black-Scholes model requires the use of highly subjective and complex assumptions which determine the fair value of share-based awards, including the
options expected term and the price volatility of the underlying stock. For restricted stock units, stock-based compensation expense is calculated based on the fair market value of our stock on the date of grant.

On November 10, 2005, the Financial Accounting Standards Board (FASB) issued FASB Staff Position No.
FAS 123(R)-3 Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards (FSP 123(R)-3). We have elected to adopt the alternative transition method provided in the FSP 123(R)-3 for calculating the
tax effects of stock-based compensation pursuant to SFAS 123(R). The alternative transition method provides a simplified method to establish the beginning balance of the additional paid-in capital pool (APIC Pool) related to the tax
effects of employee stock-based compensation, and to determine the subsequent impact on the APIC Pool and consolidated statements of cash flows of the tax effects of employee stock-based compensation awards that are outstanding upon adoption of SFAS
123(R). The adoption of FSP 123(R)-3 did not have an impact on our overall consolidated financial position, results of operations or cash flows. Also see Note 8 Stock-Based Compensation for additional information.

SFAS 123(R) prohibits the recognition of a deferred tax asset for an excess tax benefit that has not yet been realized. As a result, we will only
recognize a benefit from stock-based compensation in paid-in-capital if an incremental tax benefit is realized after all other tax attributes currently available to us have been utilized. In addition, we have elected to account for the indirect
benefits of stock-based compensation on the research tax credit through the consolidated statement of income (continuing operations) rather than through paid-in-capital.

FOREIGN CURRENCY REMEASUREMENT  |  The U.S. dollar is the functional currency for all of our foreign subsidiaries. Assets and liabilities that are not denominated in the functional currency
are remeasured into U.S. dollars and the resulting gains or losses are included in interest and other income, net. Such gains or losses have not been material for any period presented.

RESEARCH AND DEVELOPMENT EXPENSES  |  Research and development costs are charged to expense as incurred.

ADVERTISING EXPENSES  |  We expense advertising costs in the period in which they are incurred. Advertising expenses totaled
$9.1 million in 2006, $9.6 million in 2005, and $8.2 million in 2004.

NEW ACCOUNTING PRONOUNCEMENTS  |  In July
2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an interpretation of SFAS 109 (FIN 48). FIN 48 prescribes a comprehensive model for recognizing, measuring, presenting
and disclosing in the financial statements tax positions taken or expected to be taken on a tax return, including a decision whether to file or not to file in a particular jurisdiction. FIN 48 is effective for fiscal years beginning after
December 15, 2006. If there are changes in net assets as a result of application of FIN 48 these will be accounted for as an adjustment to retained earnings. We are currently assessing the impact of FIN 48 on our consolidated financial position
and results of operations. Based on our preliminary analysis, we expect a substantial portion of our income taxes payable balance of $125.2 million as of December 29, 2006 to be reclassified in 2007 as a non-current liability.

On September 13, 2006, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin No. 108, Considering the
Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (SAB 108), which provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements
should be considered in quantifying a current year misstatement. The guidance became effective for our fiscal year 2006. Our adoption of SAB 108 did not have an impact on our consolidated financial position and results of operations.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 158, Employers Accounting for Defined Benefit Pension
and Other Post-retirement Plans  an amendment of FASB Statements No. 87, 88, 106, and 132(R) (SFAS 158). SFAS 158 requires an employer to recognize the over-funded or under-funded status of a defined benefit
post-retirement plan (other than a multiemployer plan) as an asset or liability in its statement of financial position to recognize changes in that funded status in the year in which the changes occur through comprehensive income of a business
entity or changes in unrestricted net assets of a not-for-profit organization. The provisions of SFAS 158 require an employer with publicly traded equity securities to recognize the funded status of a defined benefit post-retirement plan and to
provide the required disclosures as of the end of the fiscal year ending after December 15, 2006. The adoption of SFAS 158 did not have an impact on our consolidated results of operations. The incremental effect on our consolidated balance
sheet as at December 29, 2006 is summarized in Note 11- Employee Benefits Plans.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157,
Fair Value Measurements (SFAS 157). SFAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements. The changes to current practice resulting from the application of SFAS 157
relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. We do not believe that the adoption of the provisions of SFAS 157 will materially impact our consolidated financial position and results of operations.

Note 3:    Income Per Share

In accordance with Statement of Financial Accounting
Standards No. 128, Earnings Per Share (SFAS 128) 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 options, restricted stock units, and 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 estimated deferred tax benefit or detriment associated with stock-based compensation expense.

In applying the treasury stock method, we excluded 39.7 million stock options for the year ended December 29, 2006 because their effect was anti-dilutive. Anti-dilutive stock options totaled
37.9 million for the year ended December 30, 2005 and 32.1 million for the year ended December 31, 2004. While the stock options are currently anti-dilutive, they could be dilutive in the future. All restricted stock units
outstanding as of December 29, 2006 were in-the-money and included in our treasury stock calculation. A reconciliation of basic and diluted income per share is presented below:

The following tables show the gross unrealized losses and fair values of our investments in an
unrealized loss position as of December 29, 2006 and December 30, 2005, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position. The unrealized losses on these
investments were primarily due to interest rate fluctuations. We have the ability and intent to hold these investments until recovery of their carrying values. We also believe that we will be able to collect all principal and interest amounts due to
us at maturity given the high credit quality of these investments. Accordingly, we considered these unrealized losses to be temporary in nature at December 29, 2006 and December 30, 2005.

Note 5:    Deferred Income Taxes and Other Assets, Net

Deferred income taxes reflect the effect of temporary differences between asset and liability amounts that are recognized for financial reporting purposes
and amounts that are recognized for income tax purposes. These deferred taxes are measured by applying currently enacted tax laws. Valuation allowances are recognized to reduce deferred tax assets to the amount that will more likely than not be
realized. In assessing the likelihood of realization, we consider estimates of future taxable income.

Deferred income taxes and other
assets, net consisted primarily of the non-current portion of deferred tax assets of $41.0 million at December 29, 2006 and $29.4 million at December 30, 2005.

Also included in Deferred income taxes and other assets, net are acquired intangible assets consisting of market-ready technology and other intangible assets. We continue to amortize other intangible assets on a
straight-line basis over their estimated useful lives. We purchased $0.3 million of intangible assets in 2006. Amortization of all acquired intangible assets was $1.4 million in 2006, $2.4 million in 2005, and $4.4 million in 2004. The net carrying
value of our intangible assets as of December 29, 2006 was $0.5 million, compared with $1.6 million as of December 30, 2005. Amortization expense for these intangible assets is expected to be $0.3 million in 2007 and $0.1 million in both
2008 and 2009.

Note 6:    Commitments and Contingencies

OPERATING AND CAPITAL LEASE COMMITMENTS  |  We lease facilities and equipment under non-cancelable lease agreements expiring at
various times through 2011. The facility leases generally require us to pay property taxes, insurance, maintenance, and repair costs. Total rental expense under all operating leases amounted to $10.6 million in 2006, $9.3 million in 2005, and $9.1
million in 2004. 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 leases and capital lease obligations are as of
December 29, 2006:

As of December 30, 2005,
capital lease obligations totaled $6.2 million of which $2.4 million was classified as current within Accrued liabilities.

OTHER
COMMITMENTS  |  In addition to these operating leases and capital lease 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 material to our financial condition or results of operations.

INDEMNIFICATION AND PRODUCT WARRANTY  |  We indemnify certain customers, distributors, suppliers, and subcontractors for attorney 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. In general,
there are limits on, and exceptions to, our potential liability for indemnification relating to intellectual property infringement claims. 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 products, for varying lengths of
time, against defects in materials, workmanship and non-conformance to our specifications. We provide for known product issues if a loss is probable and can be reasonably estimated. If there is a material increase in customer claims compared with
our historical experience, or if costs of servicing warranty claims are greater than expected, we may record a charge against cost of sales.

The following table summarizes the activity related to our product warranty liability for 2006 and 2005:

COMMON STOCK REPURCHASES  |  Since the inception of our
stock repurchase program in 1996 through December 29, 2006, our board of directors has authorized 108 million shares for repurchase and we have repurchased a total of 93.7 million shares of our common stock for an aggregate cost of
$2.0 billion. All shares were retired upon acquisition. On December 29, 2006, 14.3 million shares remained authorized for repurchase under our stock repurchase program.

Common stock repurchase activities for 2006, 2005, and 2004 were as follows:

Note 8:    Stock-Based Compensation

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. On May 10, 2005, our stockholders approved Alteras 2005 Equity Incentive Plan (the 2005 Plan). The 2005 Plan replaced our 1996 Stock
Option Plan (the 1996 Plan) and our 1998 Director Stock Option Plan (the 1998 Plan) before their expiration and is now Alteras only plan for providing 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 awards, restricted stock units (RSUs), stock appreciation rights, and stock
bonus awards. Prior to 2006, we granted only stock options under the 2005 Plan. In 2006, awards granted under the 2005 Plan consisted of stock options and RSUs. The majority of awards of stock options and RSUs granted under the 2005 Plan vest over
four years. Stock options granted under the 2005 Plan have a maximum contractual term of ten years.

On May 9, 2006, the stockholders
approved an amendment to the 2005 Plan to increase by 10 million the number of shares of common stock reserved for issuance under the 2005 Plan. As of December 29, 2006, the 2005 Plan had a total of 25.9 million shares reserved for
future issuance, of which 17.9 million shares were available for future grants.

##### Table of Contents

PRIOR STOCK OPTION PLANS  |  Prior to stockholder approval of the 2005 Plan on
May 10, 2005, we granted stock options under the 1996 Plan and the 1998 Plan. The 1996 Plan provided for the periodic issuance of stock options to our employees, and the 1998 Plan provided for the periodic issuance of stock options to members
of our board of directors who were not employees. The vesting period for the options granted under these plans is one to five years. The maximum contractual term of options granted under these plans is ten years.

As of December 29, 2006, the 1996 Plan had 48.9 million shares reserved for future issuance and the 1998 Plan had 0.4 million shares
reserved for future issuance. Shares reserved for future issuance under the 1996 Plan and the 1998 Plan are for stock options previously granted that remained outstanding as of December 29, 2006. We may no longer grant awards under these plans.

Prior to the 1996 and 1998 Plans, we granted stock options under various other plans. The contractual terms for the majority of awards
granted under these plans were consistent with the 1996 and 1998 Plans. As of December 29, 2006, 0.1 million shares were reserved for issuance for stock options previously granted under these plans that remained outstanding as of
December 29, 2006. We may no longer grant awards under these plans.

A summary of shares available for grant under our 2005 Plan is as
follows:

| | --- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) |  | During the year ended December 29, 2006, we granted 2,922,491 restricted stock units, of which 171,400 were forfeited during the year. For purposes of determining the number of
shares available for grant under the 2005 Plan against the maximum number of shares authorized, each restricted stock unit granted reduces the number of shares available for issuance by 2.25 shares and each restricted stock unit cancelled increases
shares available for issuance by 2.25 shares.

$69.6 million, $52.7 million and $76.1 million, respectively. The intrinsic value represents the total pre-tax value received by option holders upon the exercise of stock options during the period.

The net tax benefit realized from the exercise of non-qualified stock options, the disqualifying dispositions from the ESPP Shares, and the vesting of
restricted stock was $16.9 million for the year ended December 29, 2006, compared with $18.7 million for the year ended December 30, 2005 and $28.9 million for the year December 31, 2004.

EMPLOYEE STOCK PURCHASE
PLAN  |  As implemented, our 1987 Employee Stock Purchase Plan (ESPP) 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 will be automatically withdrawn from the current offering period following the purchase of shares on the purchase date and will be automatically
re-enrolled in the immediately following offering period.

On May 9, 2006, the stockholders approved an amendment to the ESPP to
increase the number of shares reserved for issuance from 19.7 million to 20.7 million shares. As of December 29, 2006, 2.6 million shares were available for future issuance under the ESPP. Sales under the ESPP were
1.2 million shares of common stock at an average price of $14.17 per share for the year ended December 29, 2006, 1.0 million shares of common stock at an average price of $15.43 per share for the year ended December 30, 2005, and
0.8 million shares of common stock at an average price of $16.79 per share for the year ended December 31, 2004.

Adoption
of SFAS 123(R)

On December 31, 2005, the first day of our 2006 fiscal year, we adopted SFAS 123(R) using the modified
prospective transition method. SFAS 123(R) requires the measurement and recognition of compensation expense for all stock-based awards made to our employees and directors, including employee stock options and other stock-based awards, based on
estimated fair values. The following table summarizes the impact of stock-based compensation expense on our consolidated statements of income and net income per common share for the year ended December 29, 2006:

##### Table of Contents

Prior to our adoption of SFAS 123(R), cash retained as a result of tax deductions relating to
stock-based compensation was presented in operating cash flows along with other tax cash flows. SFAS 123(R) requires a classification change in the statement of cash flows. As a result, tax benefits relating to excess stock-based compensation
deductions, which had been included in operating cash flow activities, are now presented as financing cash flow activities (total cash flows remain unchanged) as summarized below:



|                                                 |  |   |         |

At December 29, 2006, unamortized stock-based compensation expense related to outstanding
unvested stock options, RSUs, and ESPP Shares that are expected to vest was approximately $79 million. This unamortized stock-based compensation expense is expected to be recognized over a weighted average period of approximately 2.5
years. In addition to the expense for outstanding unvested stock options, RSUs and ESPP Shares, we will incur significant additional expense during fiscal year 2007 related to new awards granted during 2007.

Under the modified prospective recognition method, prior period financial statements are not restated. Prior to the adoption of SFAS 123(R), as required
by SFAS No. 148, Accounting for Stock-Based Compensation, Transition and Disclosure, we disclosed the following pro forma information to illustrate the effect on our net income and net income per share as if we had recorded
stock-based compensation expense for the years ended 2005 and 2004 under SFAS 123:

Valuation of Stock-Based Compensation

Stock Options and ESPP Shares

We
estimate the fair value of stock options and ESPP Shares on the date of grant using the Black-Scholes option-pricing model. The Black-Scholes model was developed to estimate the fair value of freely tradable, fully transferable options without
vesting restrictions. However, stock options granted under our stock option plans and ESPP Shares are not freely tradable, or transferable, and have vesting restrictions.

The Black-Scholes model requires our estimate of highly subjective assumptions, which greatly affect the
fair value of each stock option and ESPP Share. The assumptions used to estimate the fair value of stock options and ESPP Shares granted during the years ended 2006, 2005, and 2004 were as follows:

For stock options, our expected term estimate represents the weighted average term for stock
options that have completed the full contractual term based on the 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. Our calculation of fair value per share for stock options and ESPP Shares assumes no expected dividends.

We monitor the assumptions used to compute the fair value of stock options and ESPP Shares and revise our methodology as appropriate.

RSUs

For RSUs,
stock-based compensation expense is calculated based on the fair market value of our stock on the date of grant, multiplied by the number of RSUs granted. The grant-date value of RSUs, less estimated pre-vest forfeitures, is recorded on
a straight-line basis, over the vesting period. The vesting period for RSUs is generally four years.

As of December 29, 2006, we have $4.8 million of California research and development tax
credit carry forward to be used for an indefinite period of time.

We maintain within our income taxes payable account reserves for tax
contingencies. These reserves involve considerable judgment and estimation and are continuously monitored by management based on the best information available including changes in tax regulations, the outcome of relevant court cases, and other
information. We are currently under examination by various taxing authorities. Although the outcome of any tax audit is uncertain, we believe we have adequately provided in our consolidated financial statements for any additional taxes that we may
be required to pay as a result of such examinations. If the payment ultimately proves to be unnecessary, the reversal of these tax liabilities would result in tax benefits being recognized in the period we determine such liabilities are no longer
necessary. However, if an ultimate tax assessment exceeds our estimate of tax liabilities, an additional tax provision will be recorded. The impact of such adjustments in our tax accounts could have a material impact on our results of operations in
future periods.

We calculate our current and deferred tax provision based on estimates and assumptions that could differ from the actual
results reflected in income tax returns filed. Adjustments for differences between tax provisions and tax returns are recorded when identified, which is generally in the third or fourth quarter of our subsequent year.

For the fiscal year ended December 29, 2006, we recognized a tax benefit of approximately $4.0 million from the closure of a foreign income tax
audit. For the fiscal year ended December 30, 2005, we recognized a tax benefit of approximately $12.6 million from the settlement of federal and California income tax audits. The resolution of the federal and California income tax audits
included tax years 1993 through 2001. For the fiscal year ended December 31, 2004, we recognized a tax benefit of approximately $17.1 million related to the conclusion of an examination by the Hong Kong Inland Department of Revenue
(IRD) of our tax returns of our wholly-owned subsidiary, Altera International, Limited. The examination included tax years 1997 through 2003.

Unremitted earnings of our foreign subsidiaries included in retained earnings in our
consolidated balance sheet aggregated to approximately $262.0 million at December 29, 2006. 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. Our federal provision includes U.S. income tax on certain foreign based income.

On October 22, 2004, the American Jobs Creation Act of 2004 (AJCA) was enacted into law. The AJCA provides for a special one-time elective dividends received deduction of 85% for certain foreign earnings that are
repatriated by the end of 2005. During the fiscal year ended December 30, 2005, we repatriated $535.1 million of foreign earnings of which $500 million was an extraordinary dividend under the AJCA. As a result, we recorded an additional
$24.6 million tax provision in 2005.

Note 10:    Segment and Geographic Information

We operate in a single industry segment comprised of the design, development, manufacture, and sale of PLDs, IP cores, and associated development tools.
Our sales by major geographic area are based on the geographic location of the OEMs or the distributors who purchased our products. For sales to our distributors, their geographic locations may be different from the geographic locations of the
ultimate end customers.

Note 11:    Employee Benefits Plans

Altera offers various retirement benefit plans for U.S. and non-U.S. employees. Total contributions to these plans are charged to operations and were $4.4
million in 2006, $3.8 million in 2005, and $3.4 million in 2004. For employees in the U.S., we have a plan to provide retirement benefits for our eligible employees, known as the Altera Corporation Savings and Retirement Plan (the Savings
Plan). As allowed under Section 401(k) of the Internal Revenue Code, the Savings Plan allows tax deferred salary deductions for eligible employees. Our Retirement Plans Committee administers the Savings Plan. Participants in the Savings
Plan may make salary deferrals of up to 20% of the eligible annual salary, limited by the maximum dollar amount allowed by the Internal Revenue Code. For every dollar deferred under the Savings Plan, we make a matching contribution equal to 100% up
to the first 5% of the salary deferred with a maximum of $2,000 per participant per year. After three 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 Savings 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.

We allow our U.S.-based officers, director-level employees, and our board members 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. At December 29, 2006, there were approximately 140 participants in the NQDC Plan who self-direct their
investments in the NQDC Plan. 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. The NQDC Plan participants are prohibited from investing NQDC Plan contributions in Altera common stock. The
balance of the NQDC Plan assets and obligations was $69.4 million as of December 29, 2006 and $61.6 million as of December 30, 2005.

Investment income or loss earned by the NQDC Plan is recorded as Interest and other income, net. The investment income also represents an increase in the future payout to employees and is treated as current period compensation expense.
Income earned by the NQDC Plan does not impact, nor has it ever impacted, our income before income taxes, net income, or cash balances. The following table presents the net investment gains and corresponding compensation expense for the years ended
2006, 2005 and 2004.

In addition, we also sponsor a retiree medical plan providing medical benefits to eligible
retirees and their spouses. Benefits are available to employees hired on or before July 1, 2002 who retires from Altera at or after age 55 if they have at least 10 years of service. Effective January 1, 2005, future participation is also
limited to existing employees who were age 40 or older as of January 1, 2005. As of December 29, 2006 and December 30, 2005, we had $7.4 million and $5.0 million, respectively, recorded in Other non-current liabilities for this plan.

In addition, we offer to U.S. and non-U.S employees participation in the Service Award
Program (SAP). The SAP provides employees with one to three weeks of additional paid vacation upon their attainment of five, ten, fifteen, and twenty year service anniversaries. As of December 29, 2006 and December 30, 2005, we
had $6.6 million and $6.2 million, respectively, included in Accrued compensation and related for this program.

Note
12:    Legal Proceedings

We have been named as a party to several lawsuits 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). A hearing on that motion is currently scheduled for April 20, 2007.

The
consolidated California state court action names Altera Corporation as a nominal defendant and the following current and former Altera officers and directors as defendants: John P. Daane, Nathan M. Sarkisian, Denis M. Berlan, Robert W. Reed,
Robert J. Finocchio, Jr., Kevin McGarity, Paul Newhagen, William E. Terry, Susan Wang, Charles M. Clough, Rodney Smith, Michael B. Jacobs, Katherine E. Schuelke, Deborah Reiman, Michael J. Ellison, C. Wendell Bergere, Clive McCarthy, and Peter
Smyth. Plaintiffs assert claims against these individual defendants for breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate assets, unjust enrichment, violations of California Corporation Code sections 25402 and
25403, breach of fiduciary duty for insider selling and misappropriation of information, rescission, constructive trust, accounting, and deceit. Plaintiffs 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. Plaintiffs seek, among other relief, an indeterminate amount of damages from the individual
defendants and a judgment directing Altera to reform its corporate governance.

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. Altera moved to dismiss this action for lack of standing on January 29, 2007.

Among
the defendants named in these derivative actions are Altera Corporation as a nominal defendant and the following current and former officers and directors of Altera: John P. Daane, Nathan M. Sarkisian, Denis M. Berlan, Robert W. Reed, Robert J.
Finocchio, Jr., Kevin McGarity, Paul Newhagen, William E. Terry, Susan Wang, Charles M. Clough, Rodney Smith, Michael B. Jacobs, Katherine E. Schuelke, John R. Fitzhenry, Deborah Reiman, Michael J. Ellison, C. Wendell Bergere, Clive McCarthy, and
Peter Smyth. The consolidated complaint includes claims for violations of Sections 10(b), 14(a), and 20(a) of the Securities Exchange Act of 1934, breach of fiduciary duty, corporate waste, gross mismanagement, unjust enrichment, abuse of control,
insider selling and misappropriation of information, rescission, accounting, and violations of California Corporation Code sections 25402 and 25502.5. Plaintiffs claims concern the granting of stock options by Altera between 1995 and 2001 and
the alleged filing of false and misleading financial statements between 1996 and 2005.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of Altera Corporation:

We have completed integrated audits of Altera Corporations consolidated financial statements and of its internal control over financial reporting as of December 29, 2006, in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated
financial statements

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 29, 2006 and December 30, 2005, and the results of their operations and their cash flows for each of the three years in the period ended
December 29, 2006 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on
these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes 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. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 8 to the consolidated financial statements, the Company changed the manner in which it accounts for stock-based compensation in
fiscal 2006.

Internal control over financial reporting

Also, in our opinion, managements assessment, included in Managements Report on Internal Control over Financial Reporting appearing under
Item 9A, that the Company maintained effective internal control over financial reporting as of December 29, 2006 based on criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting
as of December 29, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the COSO. The Companys management is responsible for maintaining effective internal control over financial reporting and for
its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on managements assessment and on the effectiveness of the Companys internal control over financial reporting
based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over
financial reporting, evaluating managements assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our
audit provides 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.

##### Table of Contents

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.

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 and 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 29, 2006, 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.

##### Table of Contents

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 29, 2006. In making this assessment, our management used the criteria set forth in Internal
Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the results of this assessment, management (including our chief executive officer and our chief financial
officer) has concluded that, as of December 29, 2006, our internal control over financial reporting was effective.

The attestation
report concerning managements assessment of the effectiveness of our internal control over financial reporting as of December 29, 2006, issued by PricewaterhouseCoopers, LLP, Independent Registered Public Accounting Firm, appears on page
62 of our 2006 Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

During the fourth quarter of 2006, we took the necessary actions to remediate the material weakness identified in our 2005 Report on Form 10-K/A, filed on
October 24, 2006, relating to our accounting for stock option grant agreement modifications. All of the following corrective actions were implemented, including testing, as of December 29, 2006:



| | § |  | We provided additional training for our finance, human resource, stock administration, and legal personnel covering the equity grant process and the accounting and
financial reporting for equity awards and modifications of such awards.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | § |  | We adopted procedures designed to ensure:
| | - |  | -----------------------------------------



| |  |  | better coordination and communication among the finance, human resources, and legal functions to identify in advance personnel actions that might result in a
modification of an stock grant agreement;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | proper authorization for any stock grant agreement modification, including a review of the material terms of all agreements relating to termination of employment,
by our Chief Executive Officer, Chief Financial Officer (or acting Chief Financial Officer), and General Counsel, as well as our finance and human resources personnel;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | proper accounting under generally accepted accounting principles of any modifications of stock awards; and
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | validation of critical stock administration data fields including employee termination dates and stock award cancellation dates.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------

We hired a new Chief Financial Officer with substantial accounting and finance expertise. The new Chief Financial Officer took part in our year-end
financial reporting process after joining the company on January 15, 2007.

The above actions have strengthened our internal controls
over financial reporting, and as of December 29, 2006, we have remediated the material weakness identified in our 2005 Report on Form 10-K/A.
