Microchip Technology continued 
to deliver outstanding performance 
throughout all segments of our 
strong enterprise during fiscal 
year 2006. 

For the fi scal year ending March 31, 
2006, Microchip’s net sales were 
$927.9 million, increasing 9.6% 
from net sales of $846.9 million 
for the fi scal year ending March 31, 
2005 and establishing a new
record level. Non-GAAP net
income for fiscal 2006 was 
$273.0 million, an increase of 
20.4% over non-GAAP net income 
in the prior fiscal year of $226.8 
million. We achieved record gross 
margins and operating margins of 
59.4% and 35.2%, respectively, 
in fiscal 2006. Our balance sheet 
continued to strengthen, and 
we generated $450.4 million of 
net cash (prior to our dividend 
payments of $120.1 million and 
stock buy-back activity of $3.3 
million), driven by our sound 
operating results and successful 
business model. 

Microchip increased its cash
dividend payment every quarter 
during fiscal 2006, resulting 
from strong net cash generation 
throughout the fiscal year. This 
allowed shareholders to benefit 
even further from the Company’s 
solid performance. Microchip’s 
total annual dividend payment in 
fiscal 2006 was $0.57 per share, 
an increase of 174% over the
annual dividend payment of 
$0.208 per share in fiscal 2005. 
Cash dividend payments to
shareholders in fiscal 2006
totaled $120.1 million.

Superior Financial
Performance
These outstanding financial results 
place Microchip in a leadership 
position when compared to most 
other semiconductor manufactur-
ers in areas such as sales growth, 
operating profit, gross margin, 
operating margin, earnings per 
share, cash generation, stock price 
performance and dividend payment 
and growth – which all lead to
Microchip producing significant 
value to our shareholders.

“These
outstanding
financial
results place
Microchip
in a
leadership
position...”

We consider our employees to
be Microchip’s greatest strength – 
the critical ingredient that
continues to power Microchip 
ahead in reaching ever new
highs across all segments of
the business.

In the fourth quarter of fi scal 2006, 
we reached our long-term gross 
margin target of a record 60%.
Microchip achieved the 60% 
target earlier than anticipated 
thanks to our richening product mix, 
an aggressive conversion to Flash 
and mixed-signal microcontrollers 
by our customers, continued 
strong execution in Fab 4 and 
depreciation rolling off in our other 
factories. Given our expectations 
for continued performance gains, 
we raised our long-term (two to 
three years out) gross margin 
guidance to a record 62%.

New Initiatives for
Additional Growth 
In order to take higher levels of 
direct control over demand
creation for our products, Microchip 
undertook several key initiatives in 
fi scal 2006.

Our sustained growth and
accomplishments are the result
of many factors, including a
successful business model that 
has thrived in both the ups 
and downs of the cyclical 
semiconductor industry 
and a unique company 
culture that embraces 
continuous improvement, 
teamwork and employee 
empowerment.

The microchipDIRECT online
procurement site debuted,
expanding our e-commerce
services and customer support 
functions. This comprehensive 
online resource provides Micro-
chip’s customers worldwide with 
additional features previously only 
available through Microchip sales 
offices, including credit lines, 
credit-card payments, competitive 
pricing from local sales teams, 
and e-mail notification of orders, 
deliveries and quote status.

Additional investments in fiscal 
2006 enabled us to provide 24/7 
technical support, hire additional 
local field applications engineers, 
establish 23 Regional Training 

Centers worldwide and offer 
direct production programming 
services for our 8- and 16-bit 
microcontrollers. Other technical 
training included the annual
MASTERs Conference, which
was held in several worldwide 
locations and attracted record 
numbers of engineering custom-
ers who learned more about our 
products as well as new embedded 
design techniques. 

These demand creation initiatives 
provide a multitude of resources 
that our customer base can truly 
appreciate, and we are confident 
they can further enhance our 
competitive advantage. Microchip 
is committed to offering the best 

possible service and technical 
support for our 50,000+
customers around the globe.

Successful, Early
Conversion to
Lead (Pb) Free
One key business issue faced 
by the worldwide semiconductor 
industry in fiscal 2006 was the 
European Union “Restrictions on 
Hazardous Substances” (RoHS) 
directive. This directive limits the 
amount of lead (Pb) in electronic 
equipment. It was scheduled to 
go into effect on July 1, 2006, 
and governs all electronic equip-
ment manufactured or sold in the 
European Union member countries. 

Understanding the potential
impact on our business and 
Microchip’s commitment to
environmental responsibility,
a dedicated cross-functional 
team began planning four years 
ago for the necessary conversion 
of our manufacturing activities. 
Our employees executed this plan
flawlessly, allowing Microchip to
become one of the first semi-
conductor companies to convert 
product packaging to environ-
mentally friendly Pb-free plating. 
This in turn enabled our
customers to eliminate Pb from 
their manufacturing processes 
well ahead of schedule.

Aggressive New
Product Development 
During the fiscal year, our
employees carried out numerous 
new product development
strategies in many important
areas, further expanding our 
strong product portfolio of 8- and 
16-bit microcontrollers, 16-bit 
digital signal controllers, analog 
ICs and serial EEPROMs. 

Microchip aggressively pushed 
into the 16-bit controller space 
by announcing 49 new 16-bit 
PIC® microcontrollers and dsPIC® 
digital signal controllers. These 
devices offer critical advantages 
such as pinout compatibility, 
software compatibility, peripheral 
compatibility and common
development tools. 

The PIC24 family of 16-bit 
microcontrollers is comprised
of two series. The PIC24F offers 
a cost-effective step up in perfor-
mance, memory and peripherals 
for many applications that are 
pushing the envelope of 8-bit 
microcontroller capabilities. 

** Gartner Dataquest, “Top Companies Revenue from 
Shipments of 16-bit MCU – Worldwide,” April 2006.

For more demanding applica-
tions, the PIC24H offers 40 MIPS 
performance, more memory and 
additional peripherals.

innovations to ensure the largest
segment of our product portfolio 
continues to meet the evolving 
design needs of our customers.

“Working together,
our goal is to continue
to outpace the
semiconductor industry.”

Many 8-bit devices were launched 
across our entire 6- to 80-pin
families, offering additional 
memory, faster speeds and richer 
on-chip features based upon cus-
tomer demand. Microchip remains 
steadfast in our commitment to 
supporting 8-bit applications.

For the ultra-small 6-pin 
microcontrollers, Microchip
added an analog-to-digital (A/D) 
converter and doubled the
operating speed, which helps
further expand non-traditional
applications for digital
intelligence. New 8- to 64-pin
low-power Flash microcontrollers 
debuted with richer on-chip
features such as advanced 
analog and digital peripherals, 
integrated KEELOQ ® technology 
and on-chip LCD drivers.

The new dsPIC33 family of 16-bit 
digital signal controllers targets 
embedded designers who need 
high levels of performance, 
memory, on-chip peripherals and 
I/O without the complexity of 
traditional digital signal processors. 
All new 16-bit family members 
range from 64 to 256 Kbytes of 
self-programming Flash memory 
and 64- to 100-pin packages.

Today, we have a total of 70
16-bit devices sampling or in
volume production that address
the $3.8 billion 16-bit controller
market space**. More products 
are in design. We are pursuing 
16-bit customer opportunities in 
a wide range of high-performance 
applications that are separate from 
and incremental to those being 
served by an 8-bit microcontroller 
today. We believe we have the right 
silicon and development tool
solutions in place to reach our 
long-term goal of becoming the 
leading microcontroller architec-
ture in the 16-bit market, duplicat-
ing the leadership we achieved in 
the 8-bit microcontroller space.

Looking at our 8-bit PIC
microcontrollers, in fiscal 2006
Microchip drove further 

Microchip announced 14 new 
PIC18F 8-bit microcontrollers 
that deliver 40 MHz at 3 volts 
and 16 to 128 Kbytes of Flash 
memory in 28-, 40-, 64- and 80-pin 
packages. As the performance 
levels among 8-, 16- and 32-bit 
microcontrollers continue to blur 
and more designs migrate to 
lower voltages, embedded
engineers are looking for cost-
effective, yet peripheral-rich,
8-bit microcontrollers with high 
memory densities and pin counts 
that help them preserve their 
legacy 8-bit code and
development tool investments.

In certain applications, designers 
are faced with ever-increasing
demands for processing power 
and connectivity, while simultane-
ously facing the challenge to
lower power consumption and 
overall system costs. Microchip 
introduced a new series of 
PIC18F microcontrollers that
features an extra serial port
for expanded connectivity and
a faster A/D converter for
quicker measurement – all
at a 30% lower price than
the previous generation. 

A leading indicator of the 
continued acceptance of our 
microcontrollers and digital signal 

controllers is the number of 
related development systems 
shipments. Engineers utilize 
these high-performance systems 
to evaluate, compile, edit,
debug, program or emulate our 
controllers. In fiscal 2006, our 
development tools continued their 
robust growth with 73,705 total 
shipments, up from 53,311 total 
shipments in fiscal 2005. Total 
cumulative shipments now stand 
at 432,016.

In fiscal 2006, our analog and 
interface products enjoyed strong 
market acceptance with sales up 
16.6% over fiscal 2005. This high 
demand outpaced the growth of 
most of our analog competitors. 
Microchip succeeds by offering 
a broad line of analog devices, 
including linear, mixed signal, 
power management, thermal 
management and battery
management products, that are 
required in microcontroller-based 
designs today.

Many analog innovations brought 
to market this year target key 
design opportunities with the 
precision, performance and price 
benefits ideally suited for
embedded designs. For example, 
the MCP355X family of delta-
sigma A/D converters offers 

22-bit resolution with the lowest 
power consumption in the indus-
try. It is also one of the smallest 
in an 8-pin MSOP package.

Our serial EEPROM product line 
continues to grow with a new I2C™ 
family that has 1 Mbit of memory –
the highest memory density
available for such devices. 

From our serial EEPROMs to 
analog products to 8- and 16-bit 
microcontrollers to 16-bit digital 
signal controllers, Microchip’s 
business is exceptionally strong 
today. We are well positioned for 
continued market share gains in 
fiscal year 2007, thanks to the 
tireless dedication and unlimited 
contributions of our employees 
worldwide. Working together,
our goal is to continue to outpace 
the semiconductor industry.

With sincere appreciation to our 
shareholders, customers and
employees for your continued 
confidence in Microchip,

Their ongoing focus on 
continuous improvement at 
each of these steps helps 
deliver average die yields 
that are the envy of the 
semiconductor industry.  
This allows Microchip to 
lower silicon device pricing 
and respond to competitive 
pressures as needed, while 
continuing to achieve high 
gross profit margins.

Keeping manufacturing 
costs low is essential.  
When adding manufacturing

Industry Background 

Competitive pressures require manufacturers of a wide variety of products to expand product functionality and provide 

differentiation while maintaining or reducing cost.  To address these requirements, manufacturers often use integrated circuit-
based embedded control systems that enable them to: 

• 
• 
• 
• 
• 
• 

differentiate their products 
replace less efficient electromechanical control devices 
reduce the number of components in their system 
add product functionality 
decrease time to market for their products  
significantly reduce product cost 

  3

 
 
 
 
 
 
 
 
 
 
 
 
Embedded control systems have been incorporated into thousands of products and subassemblies in a wide variety of 

applications and markets worldwide, including: 

• 

• 
• 
• 
• 
• 

automotive comfort, safety and   
entertainment applications 
remote control devices 
handheld tools 
home appliances 
portable computers 
robotics  

• 

cordless and cellular telephone  
accessories 
•  motor controls 
• 
• 
• 
• 

security systems 
educational and entertainment devices 
consumer electronics 
power supplies 

Embedded control systems also facilitate the emergence of new classes of products.  Embedded control systems typically 

incorporate a microcontroller as the principal active, and sometimes sole, component.  A microcontroller is a self-contained 
computer-on-a-chip consisting of a central processing unit, non-volatile program memory, random access memory for data 
storage and various input/output peripheral capabilities.  In addition to the microcontroller, a complete embedded control 
system incorporates application-specific software and may include specialized peripheral device controllers, non-volatile 
memory components such as EEPROMs, and various analog and interface products. 

The increasing demand for embedded control has made the market for microcontrollers one of the larger segments of the 

semiconductor market.  Microcontrollers are currently available in 4-bit through 32-bit architectures.  4-bit microcontrollers 
are relatively inexpensive, but they generally lack the minimum functionality required in most applications and are typically 
used in relatively simple applications.  8-bit microcontrollers remain very cost-effective for a wide range of high volume 
embedded control applications and, as a result, continue to represent the largest portion of the overall microcontroller market.  
16-bit and 32-bit microcontrollers provide higher performance and functionality, and are generally found in more complex 
embedded control applications.  

Most microcontrollers shipped today are ROM-based and must be programmed by the semiconductor supplier during 

manufacturing, resulting in 8-12-week lead times, based on market conditions, for delivery of such microcontrollers.  In 
addition to delayed product introduction, these long lead times can result in potential inventory obsolescence and temporary 
factory shutdowns when changes in the firmware are required. To address these issues, some suppliers offer programmable 
microcontrollers that can be configured by the customer in the customer’s manufacturing line, thus significantly reducing 
lead time and inventory risks when the inevitable firmware changes occur.  While these microcontrollers were initially 
expensive relative to ROM-based microcontrollers, manufacturing technology has evolved over time to the point where 
reprogrammable microcontrollers are now available for little to no premium over ROM-based microcontrollers, thus 
providing significant value to microcontroller customers.  As a result, reprogrammable microcontrollers are the fastest 
growing segment of the microcontroller market.  

Our Products 

Our strategic focus is on embedded control solutions, including: 

•  microcontrollers 
• 
• 
• 
•  memory products 

development tools 
application-specific standard products 
analog and interface products 

We provide highly cost-effective embedded control solutions that also offer the advantages of small size, high 

performance, low voltage/power operation and ease of development, enabling timely and cost-effective embedded control 
product integration by our customers. 

  4

 
 
 
 
 
 
 
 
 
 
Microcontrollers 

We offer a broad family of microcontroller products featuring a unique, proprietary architecture marketed under the 
PIC® brand name.  We believe that our PIC product family is a price/performance leader in the worldwide microcontroller 
market.  We have shipped over 4 billion PIC microcontrollers to customers worldwide since their introduction in 1990.  Our 
PIC products are designed for applications requiring field-programmability, high performance, low power and cost 
effectiveness.  They feature a variety of memory technology configurations, low voltage and power, small footprint and ease 
of use.  Our performance results from a product architecture which features dual data and instruction pathways, referred to as 
a Harvard dual-bus architecture; a Reduced Instruction Set Computer, referred to as RISC; and variable length instructions; 
all of which provide significant speed advantages over alternative single-bus, Complex Instruction Set Computer 
architectures, referred to as CISC.  With almost 350 microcontrollers in our product portfolio, we target the 8-bit and 16-bit 
microcontroller markets.  Additionally, our scalable product architecture allows us to successfully target both the entry-level 
of the 32-bit microcontroller market, as well as the 4-bit microcontroller marketplace, significantly enlarging our addressable 
market.  

Digital Signal Controllers (DSC) are a subset of our 16-bit Microcontroller offering.  Our dsPIC® Digital Signal 
Controller families integrate the control features of high-performance 16-bit microcontrollers with the computation 
capabilities of Digital Signal Processors (DSPs), along with a wide variety of peripheral functions making them suitable for a 
large number of embedded control applications.  Our dsPIC product family offers a broad suite of hardware and software 
development tools, software application libraries, development boards and reference designs to ease and expedite the 
customer application development cycle.  With its field-re-programmability, large selection of peripheral functions, small 
footprint and ease of use, we believe that our dsPIC Digital Signal Controllers enlarge our addressable market. 

We have used our manufacturing experience and design and process technology to bring additional enhancements and 

manufacturing efficiencies to the development and production of our PIC family of microcontroller products.  Our extensive 
experience base has enabled us to develop our advanced, low cost user programmability feature by incorporating non-volatile 
memory, such as Flash, EEPROM and EPROM Memory, into the microcontroller, and to be a leader in reprogrammable 
microcontroller product offerings. 

Development Tools  

We offer a comprehensive set of low-cost and easy-to-learn application development tools.  These tools enable system 

designers to quickly and easily program a PIC microcontroller and dsPIC Digital Signal Controllers for specific applications 
and, we believe are a key factor for obtaining design wins. 

Our family of development tools operates in the standard Windows® environment on standard PC hardware.  These tools 

range from entry-level systems, which include an assembler and programmer or in-circuit debugging hardware, to fully 
configured systems that provide in-circuit emulation hardware.  Customers moving from entry-level designs to those 
requiring real-time emulation are able to preserve their investment in learning and tools as they migrate to future PIC devices 
since all of our systems share the same integrated development environment. 

Many independent companies also develop and market application development tools that support our standard 

microcontroller product architecture.  Currently, there are more than 150 third-party tool suppliers worldwide whose products 
support our proprietary microcontroller architecture. 

We believe that familiarity with and adoption of both our and third-party development tools by an increasing number of 
product designers will be an important factor in the future selection of our embedded control products.  These development 
tools allow design engineers to develop thousands of application-specific products from our standard microcontrollers.  To 
date, we have shipped more than 430,000 development tools. 

ASSPs 

Our application-specific standard products, referred to as ASSPs, are specialized products designed to perform specific 

end-user applications, compared to our other products that are more general purpose in nature.  Our ASSP device families 
currently include, among others, our KEELOQ family of secure data transmission products. 

  5

 
 
 
 
 
 
 
 
 
 
 
Analog and Interface Products 

Our analog and interface products now consist of several families with over 450 power management, linear, mixed-

signal, thermal management and interface products.  At the end of fiscal 2006, our mixed-signal analog and interface 
products were being shipped to more than 10,000 end customers. 

We continue marketing and selling our analog and interface products into our existing microcontroller customer base, 

which we refer to as our analog “attach” strategy, as well as to new customers.  In addition to our “attach” strategy, we 
market and sell other products that may not fit our traditional PIC microcontroller and memory products customer base.  We 
market these, and all of our products, based on an application segment approach targeted, to provide customers with 
application solutions. 

Memory Products  

Our memory products consist primarily of serial electrically erasable programmable read only memory, referred to as 
Serial EEPROMs.  We sell these devices primarily into the embedded control market, and we are one of the largest suppliers 
of such devices worldwide.  Serial EEPROM products are used for non-volatile program and data storage in systems where 
such data must be either modified frequently or retained for long periods.  Serial EEPROMs have a very low I/O pin 
requirement, permitting production of very small devices.  

We address customer requirements by offering products with extremely small package sizes and very low operating 

voltages for both read and write functions.  Our memory products also feature long data retention and high erase/write 
endurance. 

Manufacturing  

Our manufacturing operations include wafer fabrication and assembly and test.  The ownership of our manufacturing 
resources is an important component of our business strategy, enabling us to maintain a high level of manufacturing control 
resulting in us being one of the lowest cost producers in the embedded control industry.  By owning our wafer fabrication 
facilities and much of our assembly and test operations, and by employing proprietary statistical process control techniques, 
we have been able to achieve and maintain high production yields.  Direct control over manufacturing resources allows us to 
shorten our design and production cycles.  This control also allows us to capture the wafer manufacturing and a portion of the 
assembly and testing profit margin. 

Our manufacturing facilities are located in: 

•  Tempe, Arizona (Fab 2) 
•  Chandler, Arizona (probe operations)  
•  Puyallup, Washington (Fab 3) (non-operational) 
•  Gresham, Oregon (Fab 4)  
•  Bangkok, Thailand (assembly, probe and test) 

Wafer Fabrication 

Fab 2 currently produces 8-inch wafers and supports manufacturing processes from 0.35 to 5.0 microns.  During fiscal 

2006, Fab 2 operated at approximately 98% of its capacity compared to approximately 96% during fiscal 2005.  Operating at 
higher percentages of capacity has a positive impact on our operating results due to the relatively high fixed costs inherent in 
wafer fabrication manufacturing. 

Fab 3 is currently non-operational and being held-for-future-use.  See “Item 6 – Selected Financial Data – Fiscal 2003 – 

Fab 3 Impairment Charge,” below at page 22, for a discussion of the status of Fab 3. 

We acquired Fab 4 in August 2002 and began production on October 31, 2003.  At March 31, 2006, Fab 4 produced 8-
inch wafers using predominantly 0.5 micron manufacturing processes and is capable of supporting technologies below 0.18 
microns.  A significant amount of clean room capacity and equipment acquired with Fab 4 can be brought on line in the 
future to support incremental wafer fabrication capacity needs.  We believe the combined capacity of Fab 2, Fab 4  and Fab 3 
will provide sufficient capacity to allow us to respond to increases in future demand. 

  6

 
 
 
 
 
 
 
 
 
 
 
 
We continue to transition products to more advanced process technologies to reduce future manufacturing costs.  We 

believe that our ability to successfully transition to more advanced process technologies is important for us to remain 
competitive.   

We outsource a small percentage of our wafer production requirements to third-party wafer foundries to augment our 

internal manufacturing capabilities. 

Assembly and Test 

We perform product assembly and testing at our facilities located near Bangkok, Thailand.  At March 31, 2006, 

approximately 66% of our assembly requirements were being performed in our Thailand facility.  As of March 31, 2006, our 
Thailand facility was testing substantially all of our wafer production.  We use third-party assembly and test contractors in 
several Asian countries for the balance of our assembly and test requirements. 

General Matters Impacting Our Manufacturing Operations 

We employ proprietary design and manufacturing processes in developing our microcontroller and memory products.  
We believe our processes afford us both cost-effective designs in existing and derivative products and greater functionality in 
new product designs.  While many of our competitors develop and optimize separate processes for their logic and memory 
product lines, we use a common process technology for both microcontroller and non-volatile memory products.  This allows 
us to more fully absorb our process research and development costs and to deliver new products to market more rapidly.  Our 
engineers utilize advanced Computer Aided Design tools and software to perform circuit design, simulation and layout, and 
our in-house photomask and wafer fabrication facilities enable us to rapidly verify design techniques by processing test 
wafers quickly and efficiently. 

Due to the high fixed costs inherent in semiconductor manufacturing, consistently high manufacturing yields have 

significant positive effects on our gross profit and overall operating results.  Our continuous focus on manufacturing 
productivity has allowed us to maintain excellent manufacturing yields at our facilities.  Our manufacturing yields are 
primarily driven by a comprehensive implementation of statistical process control, extensive employee training and selective 
upgrading of our manufacturing facilities and equipment.  Maintenance of manufacturing productivity and yields are 
important factors in the achievement of our operating results.  The manufacture and assembly of integrated circuits, 
particularly non-volatile, erasable CMOS memory and logic devices, such as those that we produce, are complex processes.  
These processes are sensitive to a wide variety of factors, including the level of contaminants in the manufacturing 
environment, impurities in the materials used and the performance of our wafer fabrication personnel and equipment.  As is 
typical in the semiconductor industry, we have from time to time experienced lower than anticipated manufacturing yields.  
Our operating results will suffer if we are unable to maintain yields at approximately the current levels. 

At the end of fiscal 2006, we owned long-lived assets (consisting of property, plant and equipment and goodwill) in the 
United States amounting to $576.9 million and $124.5 million in other countries, including $118.0 million in Thailand.  At 
the end of fiscal 2005, we owned long-lived assets in the United States amounting to $628.0 million and $106.4 million in 
other countries, including $100.6 million in Thailand. 

Research and Development (R&D) 

We are committed to continuing our investment in new and enhanced products, including development systems, and in 
our design and manufacturing process technologies.  We believe these investments are significant factors in maintaining our 
competitive position.  Our current R&D activities focus on the design of new microcontrollers, digital signal controllers, 
ASSPs, Serial EEPROM memory, analog and interface products, new development systems, software and application-
specific software libraries.  We are also developing new design and process technologies to achieve further cost reductions 
and performance improvements in existing products.   

In fiscal 2006, our R&D expenses were $94.9 million, compared to $93.0 million in fiscal 2005 and $85.4 million in 

fiscal 2004.

Sales and Distribution 

General 

We market our products worldwide primarily through a network of direct sales personnel and distributors.  

Our direct sales force focuses on a wide variety of strategic accounts in three geographical markets: the Americas, 
Europe and Asia.  We currently maintain sales and technical support centers in major metropolitan areas in North America, 
Europe and Asia.  We believe that a strong technical service presence is essential to the continued development of the 
embedded control market.  The majority of our field sales engineers (FSEs), field application engineers (FAEs), and sales 
management have technical degrees or backgrounds and have been previously employed in high technology environments.  
We believe that the technical knowledge of our sales force is a key competitive advantage in the sale of our products.  The 
primary mission of our FAE team is to provide technical assistance to customers and to conduct periodic training sessions for 
the balance of our sales team.  FAEs also frequently conduct technical seminars and workshops in major cities around the 
world. 

Distribution 

Our distributors focus primarily on servicing the product requirements of a broad base of diverse customers.  We believe 
that distributors can provide an effective means of reaching this broad and diverse customer base.  We believe that customers 
recognize Microchip for its products and brand name and use distributors as an effective supply channel.  During fiscal 2006 
and fiscal 2005, we added significant resources to our internal sales force to provide technical sales support for our customers 
in both the OEM and distribution channels.  We believe that some of our distribution partners have limited internal resources 
to support the technical sales activities associated with selling our products, and we have added our own employees to 
support these activities. 

In fiscal 2006 and fiscal 2005, we derived 65% of our net sales from sales through distributors and 35% of our net sales 
from customers serviced directly by Microchip.  Distributors accounted for 64% of our net sales in fiscal 2004.  Our largest 
distributor accounted for approximately 14% of our net sales in fiscal 2006 and approximately 13% of our net sales in fiscal 
2005 and fiscal 2004.  Our second largest distributor accounted for approximately 11% of our net sales in fiscal 2006 and 
approximately 12% of our net sales in fiscal 2005 and fiscal 2004.  No other distributor or end customer accounted for more 
than 10% of our net sales in fiscal 2006, 2005 or 2004. 

Distributors generally have broad-based rights to return product to us.  As revenue on distributor shipments is not 
recognized until the distributors sell our product to their end customers, distributor returns have no impact on our revenue. 

We also grant certain credits to our distributors.  The credits are granted to the distributors on specifically identified 
pieces of the distributors’ business to allow them to earn a competitive gross margin on the sale of our products to their end 
customers.  The credits are on a per unit basis and are not given to the distributor until they provide information regarding the 
sale to their end customer.  The effect of granting these credits establishes the net selling price from us to our distributors for 
the products and results in the net revenue recognized by us when the product is sold by the distributors to their end 
customers. 

We also provide these distributors with price protection by reducing product pricing based on market conditions, 
competitive considerations and other factors.  Price protection is granted to distributors on the inventory that they have on 
hand at the date the price protection is offered.  When we reduce the selling price of our products, it allows the distributors to 
claim a credit against their outstanding accounts receivable balances based on the new price of the inventory they have on 
hand as of the date of the price reduction.  There is no revenue recognition impact from the price protection activity. 

We do not offer material incentive programs to our distributors. 

We do not have long-term agreements with our distributors and we, or our distributors, may each terminate our 
relationship with little or no advanced notice.  The loss of, or the disruption in the operations of, one or more of our 
distributors could reduce our future net sales in a given quarter and could result in an increase in inventory returns.

Sales to customers in Asia have increased as a percentage of sales from fiscal 2004 to fiscal 2005 and from fiscal 2005 to 
fiscal 2006.  We attribute this to the fact that many of our customers are transitioning their manufacturing operations to Asia, 
as well as to the growth in the demand of customers in Asia. 

Sales to foreign customers accounted for approximately 74% of our net sales in fiscal 2006, 73% of our net sales in fiscal 

2005 and 71% of our net sales in fiscal 2004.  Our sales to foreign customers have been predominately in Asia and Europe, 
which we attribute to the manufacturing strength in those areas for automotive, communications, computing, consumer and 
industrial control products.  Americas sales include sales to customers in the United States, Canada, Central America and 
South America. 

Sales to customers in China, including Hong Kong, accounted for approximately 17% of our net sales in fiscal 2006, 
approximately 16% of our net sales in fiscal 2005 and approximately 14% of our net sales in fiscal 2004.  In fiscal 2006 and 
fiscal 2005, sales to customers in Taiwan accounted for approximately 10% of our net sales.  We did not have sales into any 
other foreign countries that exceeded 10% of our net sales during fiscal 2006, 2005 or 2004. 

Our international sales are predominately U.S. dollar denominated.  Although foreign sales are subject to certain 
government export restrictions, we have not experienced any material difficulties as a result of export restrictions to date. 

The semiconductor industry is characterized by seasonality and wide fluctuations of supply and demand.  Since a 

significant portion of our revenue is from consumer markets and international sales, our business may be subject to 
seasonally lower revenues in the third and fourth quarters of our fiscal year.  However, broad strength in our overall business 
in recent periods has had a more significant impact on our results than seasonality, and has made it difficult to assess the 
impact of seasonal factors on our business. 

Backlog 

As of April 30, 2006 our backlog was approximately $231.2 million, compared to $166.9 million as of April 29, 2005.  

Our backlog includes all purchase orders scheduled for delivery within the subsequent 12 months. 

We primarily produce standard products that can be shipped from inventory within a short time after we receive an order.  

Our business and, to a large extent, that of the entire semiconductor industry, is characterized by short-term orders and 
shipment schedules.  Orders constituting our current backlog are subject to changes in delivery schedules, or to cancellation 
at the customer’s option without significant penalty.  Thus, while backlog is useful for scheduling production, backlog as of 
any particular date may not be a reliable measure of sales for any future period.   

Competition 

The semiconductor industry is intensely competitive and has been characterized by price erosion and rapid technological 

change.  We compete with major domestic and international semiconductor companies, many of which have greater market 
recognition and greater financial, technical, marketing, distribution and other resources than we have with which to pursue 
engineering, manufacturing, marketing and distribution of their products.  Furthermore, capacity in the semiconductor 
industry is generally increasing over time and such increased capacity or improved product availability could adversely affect 
our competitive position.

We currently compete principally on the basis of the technical innovation and performance of our embedded control 

products, including the following product characteristics: 

• 
• 
• 
• 

speed 
functionality 
density 
power consumption 

• 
• 
• 
• 

reliability 
packaging alternatives 
price 
availability 

We believe that other important competitive factors in the embedded control market include: 

• 
• 
• 
• 

ease of use 
functionality of application development systems 
dependable delivery and quality 
technical service and support  

We believe that we compete favorably with other companies on all of these factors, but we may be unable to compete 

successfully in the future, which could harm our business. 

Patents, Licenses and Trademarks 

We maintain a portfolio of United States and foreign patents, expiring on various dates between 2006 and 2024.  We also 
have numerous additional United States and foreign patent applications pending.  We do not expect that the expiration of any 
particular patent will have a material impact on our business.  While we intend to continue to seek patents on our inventions 
and manufacturing processes, we believe that our continued success depends primarily on the technological skills and 
innovative capabilities of our personnel and our ability to rapidly commercialize product developments, rather than on our 
patents.  Our existing patents and any new patents that are issued may not be of sufficient scope or strength to provide 
meaningful protection or any commercial advantage to us.  In addition, the laws of certain foreign countries do not protect 
our intellectual property rights to the same extent as the laws of the United States.   

We have entered into certain intellectual property licenses and cross-licenses with other companies related to 

semiconductor products and manufacturing processes.  As is typical in the semiconductor industry, we and our customers 
have from time to time received, and may in the future receive, communications from third parties asserting patent or other 
intellectual property rights on certain of our products or technologies.  We investigate all such notices and respond as we 
believe is appropriate.  Based on industry practice, we believe that in most cases we can obtain any necessary licenses or 
other rights on commercially reasonable terms, but we cannot assure that all licenses would be on acceptable terms, that 
litigation would not ensue or that damages for any past infringement would not be assessed.  Litigation, which could result in 
substantial cost to us and require significant attention from management, may be necessary to enforce our patents or other 
intellectual property rights, or to defend us against claimed infringement of the rights of others.  The failure to obtain 
necessary licenses or other rights, or litigation arising out of infringement claims, could harm our business.   

Environmental Regulation 

We must comply with many different federal, state, local and foreign governmental regulations related to the use, 
storage, discharge and disposal of certain chemicals and gases used in our manufacturing processes.  Our facilities have been 
designed to comply with these regulations and we believe that our activities are conducted in compliance with such 
regulations.  Any changes in such regulations or in their enforcement could require us to acquire costly equipment or to incur 
other significant expenses to comply with environmental regulations.  Any failure by us to adequately control the storage, use 
and disposal of regulated substances could result in future liabilities. 

Increasing public attention has been focused on the environmental impact of electronic manufacturing operations.  While 

we have not experienced any materially adverse effects on our operations from environmental regulations, our business and 
results of operations could suffer if for any reason we fail to control the use of, or to adequately restrict the discharge of, 
hazardous substances under present or future environmental regulations. 

Employees 

As of April 30, 2006, we had 4,336 employees.  None of our employees are represented by a labor organization.  We 

have never had a work stoppage and believe that our employee relations are good.

Item 1A.  RISK FACTORS 

When evaluating Microchip and its business, you should give careful consideration to the factors listed below, in 

addition to the information provided elsewhere in this Form 10-K and in other documents that we file with the Securities and 
Exchange Commission. 

Our quarterly operating results may fluctuate due to factors that could reduce our net sales and profitability. 

Our quarterly operating results are affected by a wide variety of factors that could reduce our net sales and profitability, 

many of which are beyond our control.  Some of the factors that may affect our quarterly operating results include: 

• 
• 
• 

changes in demand or market acceptance of our products and products of our customers 
levels of inventories at our customers 
the mix of inventory we hold and our ability to satisfy orders from our inventory 

  11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 
• 
• 
• 
• 
• 
• 
• 

• 
• 

• 
• 

changes in utilization of our manufacturing capacity and fluctuations in manufacturing yields 
our ability to secure sufficient assembly and testing capacity 
availability of raw materials and equipment 
competitive developments including pricing pressures 
the level of orders that are received and can be shipped in a quarter 
the level of sell-through of our products through distribution 
changes or fluctuations in customer order patterns and seasonality 
constrained availability from other electronic suppliers impacting our customers’ ability to ship their products, 
which in turn may adversely impact our sales to those customers 
costs and outcomes of any tax audits or any litigation involving intellectual property, customers or other issues 
disruptions in our business or our customers’ businesses due to terrorist activity, armed conflict, war, worldwide 
oil prices and supply, public health concerns or disruptions in the transportation system 
property damage or other losses which are not covered by insurance 
general economic, industry or political conditions in the United States or internationally 

We believe that period-to-period comparisons of our operating results are not necessarily meaningful and that you should 

not rely upon any such comparisons as indications of future performance.  In future periods our operating results may fall 
below our public guidance or the expectations of public market analysts and investors, which would likely have a negative 
effect on the price of our common stock. 

Our operating results will suffer if we ineffectively utilize our manufacturing capacity or fail to maintain manufacturing 
yields. 

The manufacture and assembly of integrated circuits, particularly non-volatile, erasable CMOS memory and logic 
devices such as those that we produce, are complex processes.  These processes are sensitive to a wide variety of factors, 
including the level of contaminants in the manufacturing environment, impurities in the materials used, the performance of 
our wafer fabrication personnel and equipment, and other quality issues.  As is typical in the semiconductor industry, we have 
from time to time experienced lower than anticipated manufacturing yields.  Our operating results will suffer if we are unable 
to maintain yields at approximately the current levels.  This could include delays in the recognition of revenue, loss of 
revenue or future orders, and customer-imposed penalties for failure to meet contractual shipment deadlines. 

Our operating results are also adversely affected when we operate at less than optimal capacity.  Lower capacity 

utilization results in certain costs being charged directly to expense and lower gross margins. 

We are dependent on orders that are received and shipped in the same quarter and therefore limited in our visibility of 
future product shipments. 

Our net sales in any given quarter depend upon a combination of shipments from backlog and orders received in that 
quarter for shipment in that quarter, which we refer to as turns orders.  We measure turns orders at the beginning of a quarter 
based on the orders needed to meet the shipment targets that we set entering the quarter.  Historically, we have proven our 
ability to respond quickly to customer orders as part of our competitive strategy, resulting in customers placing orders with 
relatively short delivery schedules.  Shorter lead times generally mean that turns orders as a percentage of our business are 
relatively high in any particular quarter and reduces our backlog visibility on future product shipments.  Turns orders 
correlate to overall semiconductor industry conditions and product lead times.  Because turns orders are difficult to predict, 
varying levels of turns orders make our net sales more difficult to forecast.  If we do not achieve a sufficient level of turns 
orders in a particular quarter relative to our revenue targets, our revenue and operating results may suffer. 

Intense competition in the markets we serve may lead to pricing pressures, reduced sales of our products or reduced 
market share. 

The semiconductor industry is intensely competitive and has been characterized by price erosion and rapid technological 

change.  We compete with major domestic and international semiconductor companies, many of which have greater market 
recognition and substantially greater financial, technical, marketing, distribution and other resources than we do with which 
to pursue engineering, manufacturing, marketing and distribution of their products.  Emerging companies are also increasing 
their participation in the market for embedded control applications.  We may be unable to compete successfully in the future, 
which could harm our business. 

  12

 
 
 
 
 
 
 
 
 
Our ability to compete successfully depends on a number of factors both within and outside our control, including, but 

not limited to: 

• 
• 
• 
• 
• 
• 
• 
• 
• 

the quality, performance, reliability, features, ease of use, pricing and diversity of our products 
our success in designing and manufacturing new products including those implementing new technologies 
the rate at which customers incorporate our products into their own applications 
product introductions by our competitors 
the number, nature and success of our competitors in a given market 
our ability to obtain adequate supplies of raw materials and other supplies at acceptable prices 
our ability to protect our products and processes by effective utilization of intellectual property rights 
the quality of our customer service and our ability to address the needs of our customers, and 
general market and economic conditions. 

Historically, average selling prices in the semiconductor industry decrease over the life of any particular product.  The 
overall average selling prices of our microcontroller and proprietary analog and interface products have remained relatively 
constant, while average selling prices of our Serial EEPROM and non-proprietary analog and interface products have 
declined over time. 

We have experienced, and expect to continue to experience, modest pricing declines in certain of our more mature 

proprietary product lines, due primarily to competitive conditions.  We have been able to moderate average selling price 
declines in many of our proprietary product lines by continuing to introduce new products with more features and higher 
prices.  We have experienced in the past and expect to continue to experience in the future varying degrees of competitive 
pricing pressures in our Serial EEPROM products. 

We may be unable to maintain average selling prices for our products as a result of increased pricing pressure in the 

future, which could adversely impact our operating results. 

Our business is dependent on selling through distributors. 

Sales through distributors accounted for 65% of our net sales in fiscal 2006, 65% of our net sales in fiscal 2005 and 64% 

of our net sales in fiscal 2004.  Our two largest distributors together accounted for approximately 25% of our net sales in 
fiscal 2006, fiscal 2005 and fiscal 2004.  We do not have long-term agreements with our distributors and both we and our 
distributors may each terminate our relationship with little or no advanced notice.  We believe that customers recognize 
Microchip for its products and brand name and use distributors as an effective supply channel. 

During fiscal 2006 we reduced the gross margin that certain of our distributors earn when they sell our products.  We 

reduced these distributors’ gross margins because we believe these distributors did not have sufficient technical sales 
resources to properly address the marketplace for our products.  We have added a significant number of technical sales 
employees throughout our worldwide sales organization to address the support requirements for both our OEM and 
distribution customers.  We cannot predict the impact, if any, that our actions will have on our relationships with such 
distributors. 

The loss of, or a disruption in the operations of, one or more of our distributors could reduce our net sales in a given 

period and could result in an increase in inventory returns. 

Our success depends on our ability to introduce new products on a timely basis. 

Our future operating results will depend on our ability to develop and introduce new products on a timely basis that can 

compete effectively on the basis of price and performance and which address customer requirements.  The success of our new 
product introductions depends on various factors, including, but not limited to: 

• 
• 
• 

proper new product selection 
timely completion and introduction of new product designs 
development of support tools and collateral literature that make complex new products easy for engineers to 
understand and use, and 

•  market acceptance of our customers’ end products. 

  13

 
 
 
 
 
 
 
 
 
 
 
 
Because our products are complex, we have experienced delays from time to time in completing development of new 
products.  In addition, our new products may not receive or maintain substantial market acceptance.  We may be unable to 
design, develop and introduce competitive products on a timely basis, which could adversely impact our future operating 
results. 

Our success also depends upon our ability to develop and implement new design and process technologies.  
Semiconductor design and process technologies are subject to rapid technological change and require significant R&D 
expenditures.  We and other companies in the industry have, from time to time, experienced difficulties in effecting 
transitions to advanced process technologies and, consequently, have suffered reduced manufacturing yields or delays in 
product deliveries.  Our future operating results could be adversely affected if any transition to future process technologies is 
substantially delayed or inefficiently implemented. 

We must attract and retain qualified personnel to be successful, and competition for qualified personnel is intense in our 
market. 

Our success depends upon the efforts and abilities of our senior management, engineering and other personnel.  The 

competition for qualified engineering and management personnel is intense.  We may be unsuccessful in retaining our 
existing key personnel or in attracting and retaining additional key personnel that we require.  The loss of the services of one 
or more of our key personnel or the inability to add key personnel could harm our business.  We have no employment 
agreements with any member of our senior management team. 

We are dependent on several contractors to perform key manufacturing functions for us. 

We use several contractors located in Asia for a portion of the assembly and testing of our products.  We also rely on 

outside wafer foundries for a portion of our wafer fabrication.  Although we own the majority of our manufacturing 
resources, the disruption or termination of any of our contractors could harm our business and operating results.   

Our use of third parties involves some reduction in our level of control over the portions of our business that we 

subcontract.  Our future operating results could suffer if any contractor were to experience financial, operations or production 
difficulties or situations when demand exceeds capacity, or if they were unable to maintain manufacturing yields, assembly 
and test yields and costs at approximately their current levels, or if due to their locations in foreign countries they were to 
experience political upheaval or infrastructure disruption.  Further, procurement from third parties is done by purchase order 
and contracts.  If these third parties are unable or unwilling to timely deliver products or services conforming to our quality 
standards, we may not be able to qualify additional manufacturing sources for our products in a timely manner or at all, and 
such arrangements, if any, may not be on favorable terms to us.  In such event, we could experience an interruption in 
production, an increase in manufacturing and production costs, decline in product reliability, and our business and operating 
results could be adversely affected. 

We may lose sales if our suppliers of raw materials and equipment fail to meet our needs. 

Our semiconductor manufacturing operations require raw materials and equipment that must meet exacting standards.  

We generally have more than one source for these supplies, but there are only a limited number of suppliers capable of 
delivering various raw materials and equipment that meet our standards.  The raw materials and equipment necessary for our 
business could become more difficult to obtain as worldwide use of semiconductors in product applications increases.  We 
have experienced supply shortages from time to time in the past, and on occasion our suppliers have told us they need more 
time than expected to fill our orders or that they will no longer support certain equipment with updates or spare and 
replacements parts.  An interruption of any raw materials or equipment sources, or the lack of supplier support for a particular 
piece of equipment, could harm our business. 

Our operating results may be impacted by both seasonality and the wide fluctuations of supply and demand in the 
semiconductor industry. 

The semiconductor industry is characterized by seasonality and wide fluctuations of supply and demand.  Since a 

significant portion of our revenue is from consumer markets and international sales, our business may be subject to 
seasonally lower revenues in the third and fourth quarters of our fiscal year.  However, broad strength in our overall business 
in recent periods has had a more significant impact on our results than seasonality, and has made it difficult to assess the 
impact of seasonal factors on our business.  The industry has also experienced significant economic downturns, characterized 
by diminished product demand and production over-capacity.  We have sought to reduce our exposure to this industry 
cyclicality by selling proprietary products that cannot be easily or quickly replaced, to a geographically diverse base of 

  14

 
 
 
 
 
 
 
 
 
 
customers across a broad range of market segments.  However, we have experienced substantial period-to-period fluctuations 
in operating results and expect, in the future, to experience period-to-period fluctuations in operating results due to general 
industry or economic conditions. 

We are exposed to various risks related to legal proceedings or claims.  

We are currently, and in the future may be, involved in legal proceedings or claims regarding patent infringement, 

intellectual property rights, contracts and other matters.  We were involved in patent infringement litigation with Philips 
Corporation which was settled in fiscal 2005.  As is typical in the semiconductor industry, we receive notifications from 
customers from time to time who believe that we owe them indemnification or other obligations related to infringement 
claims made against the customers by third parties.  These legal proceedings and claims, whether with or without merit, could 
result in substantial cost to us and divert our resources.  If we are not able to resolve a claim, negotiate a settlement of a 
matter, obtain necessary licenses on commercially reasonable terms, reengineer our products or processes to avoid 
infringement, and/or successfully prosecute or defend our position, we could incur uninsured liability in any of them, be 
required to take an appropriate charge to operations, be enjoined from selling a material portion of our product line or using 
certain processes, suffer a reduction or elimination in value of inventories,  and our business, financial condition or results of 
operations could be harmed. 

It is also possible that from time to time we may be subject to warranty or product liability claims that could lead to 

significant expenses related to the defense of such claims, increased costs associated with the replacement of affected 
products, and a requirement to pay damages claims.  Because the systems into which our products are integrated have a 
higher cost of goods than the products we sell, these expenses and damages may be significantly higher than the sales and 
profits the company received from the products involved.  While we specifically exclude consequential damages in our 
standard terms and conditions, our ability to avoid such liabilities may be limited by applicable law.  We do have product 
liability insurance, but there is no certainty that insurance will cover all claims or be of a sufficient amount to fully protect 
against such claims.  Costs or payments we may make in connection with warranty or product liability claims may adversely 
affect the results of our operations. 

Further, we sell to customers in industries such as automotive, aerospace, and medical, where failure of their systems 
could cause damage to property or persons. We may be subject to product liability claims if our products cause the 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 either the volume of 
our sales into these applications and the frequency of system failures caused by our devices. 

Failure to adequately protect our intellectual property could result in lost revenue or market opportunities. 

Our ability to obtain patents, licenses and other intellectual property rights covering our products and manufacturing 

processes is important for our success.  To that end, we have acquired certain patents and patent licenses and intend to 
continue to seek patents on our inventions and manufacturing processes.  The process of seeking patent protection can be 
long and expensive, and patents may not be issued from currently pending or future applications.  In addition, our existing 
patents and any new patents that are issued may not be of sufficient scope or strength to provide meaningful protection or any 
commercial advantage to us.  We may be subject to or may ourselves initiate interference proceedings in the U.S. Patent and 
Trademark Office, which can require significant financial and management resources.  In addition, the laws of certain foreign 
countries do not protect our intellectual property rights to the same extent as the laws of the United States.  Infringement of 
our intellectual property rights by a third party could result in uncompensated lost market and revenue opportunities for us. 

We do not typically have long-term contracts with our customers. 

We do not typically enter into long-term contracts with our customers and we cannot be certain about future order levels 
from our customers.  When we do enter into customer contracts, the contract is generally cancelable at the convenience of the 
customer.  Even though we have over 50,000 end customers and our ten largest customers make up approximately 10% of 
our total revenue, cancellation of long-term and short-term customer contracts could have an adverse financial impact on our 
revenue and profits.   

Further, as the practice has become more commonplace in the industry, we have entered into contracts with certain 
customers that differ from our standard terms of sale. Under these contracts we commit to supply quantities of products on 
scheduled delivery dates.  If we become unable to supply the customer as required under the contract, the customer may incur 
additional production costs, lost revenues due to subsequent delays in their own manufacturing schedule, or quality related 

  15

 
 
 
 
 
 
 
 
 
issues. Under these contracts, we may be liable for the costs the customer has incurred. While we try to limit such liabilities, 
if they should arise, there may be a material adverse impact on our results of operation and financial condition. 
Business interruptions could harm our business. 

Operations at any of our manufacturing facilities, or at any of our wafer fabrication or test and assembly subcontractors, 

may be disrupted for reasons beyond our control, including work stoppages, power loss, incidents of terrorism or security 
risk, political instability, public health issues, telecommunications, transportation or other infrastructure failure, fire, 
earthquake, floods, or other natural disasters.  If operations at any of our facilities, or our subcontractors’ facilities are 
interrupted, we may not be able to shift production to other facilities on a timely basis.  If this occurs, we would likely 
experience delays in shipments of products to our customers and alternate sources for production may be unavailable on 
acceptable terms.  This could result in reduced revenues and profits and the cancellation of orders or loss of customers.  In 
addition, business interruption insurance will likely not be enough to compensate us for any losses that may occur and any 
losses or damages incurred by us as a result of business interruptions could significantly harm our business. 

We are highly dependent on foreign sales and operations, which exposes us to foreign political and economic risks. 

Sales to foreign customers account for a substantial portion of our net sales.  During fiscal 2006, approximately 74% of 
our net sales were made to foreign customers.  During fiscal 2005, approximately 73% of our net sales were made to foreign 
customers.  During fiscal 2004, approximately 71% of our net sales were made to foreign customers.  We purchase a 
substantial portion of our raw materials and equipment from foreign suppliers.  In addition, we own product assembly and 
testing facilities located near Bangkok, Thailand.  We also use various foreign contractors for a portion of our assembly and 
testing and for a portion of our wafer fabrication requirements.  Substantially all of our finished goods inventory is 
maintained in Thailand. 

Our reliance on foreign operations, foreign suppliers, maintenance of substantially all of our finished goods in inventory 
at foreign locations and significant foreign sales exposes us to foreign political and economic risks, including, but not limited 
to: 

• 
• 
• 
• 
• 
• 
• 
• 
• 
• 
• 

political, social and economic instability 
public health conditions 
trade restrictions and changes in tariffs 
import and export license requirements and restrictions 
difficulties in staffing and managing international operations 
employment regulations 
disruptions in international transport or delivery 
fluctuations in currency exchange rates 
difficulties in collecting receivables 
economic slowdown in the worldwide markets served by us, and 
potentially adverse tax consequences. 

If any of these risks materialize, our sales could decrease and our operating results could suffer. 

Interruptions in information technology systems could affect our business. 

We rely on the efficient and uninterrupted operation of complex information technology systems and networks to operate 

our business.  Any significant system or network disruption, including but not limited to computer viruses, security breach, 
and energy blackouts could have a material adverse impact on our operations, sales and operating results.  We have 
implemented measures to manage our risks related to such disruptions, but such disruptions could negatively impact our 
operations and financial results.  In addition, we may incur additional costs to remedy the damages caused by these 
disruptions or security breaches. 

The occurrence of events for which we are self-insured, or which exceed our insurance limits may affect our profitability 
and liquidity. 

We have insurance contracts with independent insurance companies related to many different types of risk; however, we 

self-insure for some risks and obligations.  In these circumstances, we have determined that it is more cost effective to self-
insure certain risks than to pay the increased premium costs in place since the disruption in the insurance market after the 

  16

 
 
 
 
 
 
 
 
 
 
events of September 11, 2001.  The risks and exposures that we self-insure include, but are not limited to, product defects, 
political risks, and patent infringement.  Should there be a loss or adverse judgment or other decision in an area for which we 
are self-insured, then our financial condition, result of operations and liquidity may be adversely affected. 

We are subject to stringent environmental regulations, which may force us to incur significant expenses. 

We must comply with many different federal, state, local and foreign governmental regulations related to the use, 
storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in our manufacturing process.  
Although we believe that our activities conform to presently applicable environmental regulations, our failure to comply with 
present or future regulations could result in the imposition of fines, suspension of production or a cessation of operations.  
Any such environmental regulations could require us to acquire costly equipment or to incur other significant expenses to 
comply with such regulations.  Any failure by us to control the use of or adequately restrict the discharge of hazardous 
substances could subject us to future liabilities.  Environmental problems may occur that could subject us to future costs or 
liabilities. 

Further, certain of our customers shipping their products into European markets are also subject to governmental 

environmental regulations such as the Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive 
(RoHS) which will be effective July 1, 2006.  These directives focus on limiting the amounts of certain elements, such as 
lead, in electrical devices.  The inability of this sub-set of our customers to use Microchip products which contain lead after 
July 2006 may adversely affect our results of operations. 

Compliance with future changes to securities laws and related regulations could result in increased costs to us.  

Changes in the laws and regulations affecting public companies, including the provisions of the Sarbanes-Oxley Act of 

2002 and rules enacted and proposed by the Securities and Exchange Commission (SEC), The NASDAQ Stock Market® 
(NASDAQ) and the New York Stock Exchange (NYSE), resulted in significantly increased costs to us in fiscal 2005 as we 
responded to their requirements.  In particular, complying with the internal control audit requirements of Sarbanes-Oxley 
Section 404 in fiscal 2005 resulted in increased internal efforts and significantly higher fees from our independent accounting 
firm.  In fiscal 2006, our costs associated with these activities were at approximately the same levels as in fiscal 2005.  
Further changes in applicable legal or accounting requirements could result in additional costs in future periods. 

This report on Form 10-K contains a report by our management on our internal control over financial reporting including 
an assessment of the effectiveness of our internal control over financial reporting as of March 31, 2006.  This Form 10-K also 
contains an attestation and report by our auditors with respect to our management’s assessment of the effectiveness of 
internal control over financial reporting under Section 404.  While these assessments and reports did not reveal any material 
weaknesses in our internal control over financial reporting, compliance with Section 404 is an ongoing process and will be 
required for each future fiscal year.  We expect that the ongoing compliance with Section 404 will continue to be both very 
costly and very challenging and there can be no assurance that material weaknesses with not be identified in future periods.  
Any adverse results from such ongoing compliance efforts could result in a loss of investor confidence in our financial 
reports and have an adverse effect on our stock price. 

Recent regulations related to equity compensation will adversely affect our earnings and our ability to attract and retain 
key personnel.    

Since our inception, we have used stock options and other long-term equity incentives as a fundamental component of 

our employee compensation packages and have accounted for them using the intrinsic value method of APB No. 25, 
“Accounting for Stock Issued to Employees.”  We believe that stock options and other long-term equity incentives directly 
motivate our employees to maximize long-term stockholder value and, through the use of vesting, encourage employees to 
remain with Microchip.  In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of 
Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), “Share-Based Payments,” (“SFAS 123R”) which changed 
U.S. Generally Accepted Accounting Principles in such a way to require us to record a charge to earnings for the fair value of 
employee stock option grants and other share based compensation beginning in the first quarter of fiscal 2007.  This 
regulation will negatively impact our earnings for those share based awards that vest beginning in fiscal 2007.  Furthermore, 
adoption of SFAS 123R will require us to make certain assumptions and judgments in the valuation of stock options that we 
may grant in the future.  A change in any of those assumptions or judgments could change the compensation expense that is 
charged against our earnings and, consequently, adversely affect our results of operations.  See also Note 1 to the 
Consolidated Financial Statements – Significant Accounting Policies:  Share-Based Payment.   

  17

 
 
 
 
 
 
 
 
 
In addition, recent regulations implemented by NASDAQ requiring shareholder approval for all stock option plans as 
well as recent regulations implemented by the NYSE prohibiting NYSE member organizations from giving a proxy to vote 
on equity-compensation plans unless the beneficial owner of the shares has given voting instructions could make it more 
difficult for us to grant equity-based awards to employees in the future.  To the extent that these or other new regulations 
make it more difficult or expensive to grant options to employees, we may incur compensation costs, productivity losses, 
change our equity compensation strategy or find it difficult to attract, retain and motivate employees, each of which could 
materially and adversely affect our business. 

The future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors. 

The market price of our common stock has fluctuated significantly in the past and is likely to fluctuate in the future.  The 

future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors, many of 
which are beyond our control, including, but not limited to: 

quarterly variations in our operating results and the operating results of other technology companies 
actual or anticipated announcements of technical innovations or new products by us or our competitors 
changes in analysts’ estimates of our financial performance or buy/sell recommendations 
changes in our financial guidance or our failure to meet such guidance 
general conditions in the semiconductor industry, and 

• 
• 
• 
• 
• 
•  worldwide economic and financial conditions. 

In addition, the stock market has experienced significant price and volume fluctuations that have particularly affected the 

market prices for many high technology companies and that often have been unrelated to the operating performance of such 
companies.  These broad market fluctuations and other factors may harm the market price of our common stock. 

The outcome of currently ongoing and future examinations of our income tax returns by the IRS could have an adverse 
effect on our results of operations. 

We are subject to continued examination of our income tax returns by the Internal Revenue Service and other tax 
authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the 
adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuing examinations 
will not have an adverse effect on future operating results. 

In the event we make acquisitions, we may not be able to successfully integrate such acquisitions or attain the anticipated 
benefits. 

While acquisitions do not represent a major part of our growth strategy, from time to time we may consider financially 
attractive and strategic acquisitions if such opportunities arise. Any transactions that we complete may involve a number of 
risks, including:  the diversion of our management’s attention from our existing business to integrate the operations and 
personnel of the acquired or combined business or joint venture, or possible adverse effects on our operating results during 
the integration process.  In addition, we may not be able to successfully or profitably integrate, operate, maintain and manage 
our newly acquired operations or employees. We may not be able to maintain uniform standards, controls, procedures and 
policies, and this may lead to operational inefficiencies.

Fab 2. 

(2)  Currently non-operational and being held-for-future-use.  Fab 3 consists of manufacturing buildings and land, with no equipment. 
(3)  Located in the Alphatechnopolis Industrial Park near Bangkok on land to which we expect to acquire title in accordance with our 

agreement with the landowner.  Progress towards obtaining full title of the land has been delayed due to a bankruptcy relating to the 
seller of the land.  At this time it is not possible to estimate when, or if, full title transfer will be completed.  We have provided 
reserves that we estimate will be adequate to obtain full title.  Such reserves are set at the estimated fair value of the land. 

In addition to the facilities we own, we lease several research and development facilities and sales offices in North 
America, Europe and Asia.  Our aggregate monthly rental payment for our leased facilities is approximately $0.4 million. 

We currently believe that our existing facilities will be adequate to meet our production requirements for the next 12 

months. 

Item 3. 

LEGAL PROCEEDINGS 

In the ordinary course of our business, we are involved in a limited number of legal actions, both as plaintiff and 
defendant, and could incur uninsured liability in any one or more of them.  Although the outcome of these actions is not 
presently determinable, we believe that the ultimate resolution of these matters will not harm our business and will not have a 
material adverse effect on our financial position, cash flows or results of operations.  Litigation relating to the semiconductor 
industry is not uncommon, and we are, and from time to time have been, subject to such litigation.  No assurances can be 
given with respect to the extent or outcome of any such litigation in the future.

On April 25, 2006, we declared a quarterly cash dividend of $0.215 per share, which was paid on May 23, 2006 to 
stockholders of record on May 9, 2006 and the total amount of such dividend was $46.0 million.  Our Board is free to change 
its dividend practices at any time and to decrease or increase the dividend paid, or not to pay a dividend, on our common 
stock on the basis of our results of operations, financial condition, cash requirements and future prospects, and other factors 
deemed relevant by our Board.  Our current intent is to provide for ongoing quarterly cash dividends depending upon market 
conditions and our results of operations. 

On April 22, 2004, our Board of Directors authorized the repurchase of up to 2,500,000 shares of our common stock in 

the open market or privately negotiated transactions.  As of March 31, 2006, 1,495,166 shares related to this authorization 
remained available to be purchased under this program.  We did not repurchase any shares of our common stock in the fourth 
quarter of fiscal 2006. 

Please refer to “Item 12, Security Ownership Of Certain Beneficial Owners And Management And Related Stockholder

Fiscal 2003 

Fab 3 Impairment Charge 

During the September 2002 quarter, we recorded a $41.5 million asset impairment charge as described below. 

During July 2000, we acquired a semiconductor manufacturing facility in Puyallup, Washington, referred to as Fab 3.  The 
original purchase consisted of semiconductor manufacturing facilities and real property.  It was our intention to bring Fab 3 
to productive readiness and commence volume production of 8-inch wafers using its 0.7 and 0.5 micron process technologies 
by August 2001.  Due to deteriorating business conditions in the semiconductor industry during fiscal 2002, we delayed the 
intended production start up of Fab 3.  Fab 3 has never been brought to productive readiness. 

In August 2002 we acquired a semiconductor manufacturing facility in Gresham, Oregon, referred to as Fab 4.  After the 
acquisition of Fab 4 was completed, we undertook an analysis of the potential production capacity at Fab 4.  The results of 
the production capacity analysis at that time led us to determine that Fab 3’s capacity would not be needed in the foreseeable 
future and during the second quarter of fiscal 2003 we committed to a plan to sell Fab 3.  Subsequently, we retained a third-
party broker to market Fab 3 on our behalf and began actively seeking potential buyers.  Accordingly, Fab 3 was classified as 
an asset held-for-sale as of September 30, 2002 and maintained that classification until March 31, 2005. 

Management determined the value assigned to the Fab 3 assets through various methods including assistance from a third-
party appraisal.  The independent third party used the market approach and considered sales of comparable properties in 
determining the fair value of Fab 3.  The comparable sales included eight properties, including our purchases of Fab 3 in July 
2000 and Fab 4 in August 2002.  Based on the results of this appraisal, we recorded an asset impairment charge on Fab 3 of 
$36.9 million, including estimated costs to sell.  The remaining value of $60.2 million was classified as an asset held-for-sale 
and was included as a component of other current assets until March 31, 2005. 

During the quarter ended September 30, 2002, we recorded an asset impairment charge of $4.6 million to write-down certain 
excess manufacturing equipment located at Fab 3 to its net realizable value of $0.2 million.  This manufacturing equipment 
became “excess” as a result of duplicate equipment acquired in the purchase of Fab 4.  The net realizable value for the excess 
manufacturing equipment was determined based on management estimates.  Substantially all of the other manufacturing 
equipment located at Fab 3 has been transferred to and will be used in our other wafer fabrication facilities located in Tempe, 
Arizona (Fab 2) and Gresham, Oregon (Fab 4). 

At March 31, 2005, we changed the classification of Fab 3 from an asset held-for-sale to an asset held-for-future-use.  Fab 3 
had been on the market for over two years, and we had not received any acceptable offers on the facility.  Over that period of 
time, our business had increased significantly and over the next several years we will need to begin planning for future wafer 
fabrication capacity as a larger percentage of Fab 4’s clean room capacity is utilized.  We determined that the appropriate 
action to take was to stop actively marketing the Fab 3 facility and hold it for its future use.  As a result of this change in 
classification, we had to assess the fair value of the Fab 3 asset to determine if any additional impairment charge was required 
upon the change in classification from “held-for-sale” to “held-for-future-use” under Statement of Financial Accounting 
Standards (“SFAS”) No. 144.  We performed a discounted cash flow analysis of the Fab 3 asset based on various financial 
projections in developing the fair value estimate given that it was the best available valuation technique for the asset.  The 
discounted cash flow analysis confirmed the carrying value of the Fab 3 asset at March 31, 2005 was not in excess of its fair 
value.  We began to depreciate the Fab 3 asset in April 2005. 

PowerSmart In-Process Research and Development Charge 

On June 5, 2002, we completed the acquisition of PowerSmart, Inc. in which we acquired all of PowerSmart’s outstanding 
capital stock and assumed certain stock options for consideration of $54.0 million in cash plus other acquisition-related costs 
of $1.2 million.  The acquisition was accounted for as a purchase business combination in accordance with SFAS No. 141, 
“Business Combinations”, and accordingly, the results of PowerSmart’s operations are included in our consolidated results 
from the date of the acquisition.  The acquisition was not considered significant under the rules and regulations of the SEC 
(Rule 3-05 of Regulation S-X). 

The purchase price was allocated among PowerSmart’s tangible and intangible assets, in-process research and development 
and goodwill.  Management determined the value assigned to the assets acquired through various methods including 
assistance from a third-party appraisal.  An allocation of $9.3 million of the purchase price was assigned to in-process 
research and development and was written off at the date of the acquisition.  The amount paid in excess of the fair value of 
the net tangible assets was allocated to separately identifiable intangible assets based upon an independent valuation analysis.  

  22

 
 
 
 
 
 
 
 
 
 
An allocation of $5.6 million of the purchase price was made to core technology and other identifiable intangible assets and 
is being amortized over an estimated useful life of seven years.  An allocation of approximately $32.3 million of the purchase 
price was made to goodwill.  None of the goodwill is deductible for tax purposes.  The goodwill related to the PowerSmart 
acquisition was reduced by $0.4 million to $31.9 million in the year ended March 31, 2005 due to a favorable settlement of a 
liability that was recorded as of the original acquisition date.

Introduction 

The following discussion should be read in conjunction with the condensed consolidated financial statements and the 
related notes that appear elsewhere in this document, as well as with other sections of this Annual Report on Form 10-K, 
including “Item 1 – Business;” “Item 6 – Selected Financial Data;” and “Item 8 – Financial Statements and Supplementary 
Data.” 

We begin our Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) with a 
summary of Microchip’s overall business strategy to give the reader an overview of the goals of our business and the overall 
direction of our business and products.  This is followed by a discussion of the Critical Accounting Policies and Estimates 
that we believe are important to understanding the assumptions and judgments incorporated in our reported financial results.  
In the next section, beginning at page 27, we discuss our Results of Operations for fiscal 2006 compared to fiscal 2005, and 
for fiscal 2005 compared to fiscal 2004.  We then provide an analysis of changes in our balance sheet and cash flows, and 
discuss our financial commitments in sections titled “Liquidity and Capital Resources,” “Contractual Obligations” and “Off-
Balance Sheet Arrangements.” 

Strategy 

Our goal is to be a worldwide leader in providing specialized semiconductor products for a wide variety of embedded 
control applications.  Our strategic focus is on embedded control products, which include microcontrollers, high-performance 
linear and mixed signal devices, power management and thermal management devices, and complementary microperipheral 
 security devices.  We provide highly cost-
products including interface devices, Serial EEPROMs, and our patented KEELOQ
effective embedded control products that also offer the advantages of small size, high performance, low voltage/power 
operation and ease of development, enabling timely and cost-effective embedded control product integration by our 
customers. 

Our manufacturing operations include wafer fabrication and assembly and test.  The ownership of our manufacturing 
resources is an important component of our business strategy, enabling us to maintain a high level of manufacturing control 
resulting in us being one of the lowest cost producers in the embedded control industry.  By owning our wafer fabrication 
facilities and much of our assembly and test operations, and by employing statistical process control techniques, we have 
been able to achieve and maintain high production yields.  Direct control over manufacturing resources allows us to shorten 
our design and production cycles.  This control also allows us to capture the wafer manufacturing and a portion of the 
assembly and test profit margin. 

We employ proprietary design and manufacturing processes in developing our embedded control products.  We believe 

our processes afford us both cost-effective designs in existing and derivative products and greater functionality in new 
product designs.  While many of our competitors develop and optimize separate processes for their logic and memory 
product lines, we use a common process technology for both microcontroller and non-volatile memory products.  This allows 
us to more fully leverage our process research and development costs and to deliver new products to market more rapidly.  
Our engineers utilize advanced computer-aided design (CAD) tools and software to perform circuit design, simulation and 
layout, and our in-house photomask and wafer fabrication facilities enable us to rapidly verify design techniques by 
processing test wafers quickly and efficiently. 

We are committed to continuing our investment in new and enhanced products, including development systems, and in 
our design and manufacturing process technologies.  We believe these investments are significant factors in maintaining our 
competitive position.  Our current research and development activities focus on the design of new microcontrollers, digital 
signal controllers, ASSPs, memory and mixed-signal products, new development systems, software and application-specific 
software libraries.  We are also developing new design and process technologies to achieve further cost reductions and 
performance improvements in existing products. 

  24

 
 
 
 
 
 
 
 
 
 
We market our products worldwide primarily through a network of direct sales personnel and distributors.  Our 

distributors focus primarily on servicing the product and technical support requirements of a broad base of diverse customers.  
We believe that our direct sales personnel combined with our distributors provide an effective means of reaching this broad 
and diverse customer base.  Our direct sales force focuses primarily on major strategic accounts in three geographical 
markets: the Americas, Europe and Asia.  We currently maintain sales and support centers in major metropolitan areas in 
North America, Europe and Asia.  We believe that a strong technical service presence is essential to the continued 
development of the embedded control market.  Many of our field sales engineers (FSEs), field application engineers (FAEs), 
and sales management have technical degrees and have been previously employed in an engineering environment.  We 
believe that the technical knowledge of our sales force is a key competitive advantage in the sale of our products.  The 
primary mission of our FAE team is to provide technical assistance to strategic accounts and to conduct periodic training 
sessions for FSEs and distributor sales teams.  FAEs also frequently conduct technical seminars in major cities around the 
world, and work closely with our distributors to provide technical assistance and end-user support. 

Critical Accounting Policies and Estimates 

General 

Our discussion and analysis of Microchip’s financial condition and results of operations is based upon our Consolidated 

Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United 
States of America.  We review the accounting policies we use in reporting our financial results on a regular basis.  The 
preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of 
assets, liabilities, revenues and expenses and related disclosure of contingent liabilities.  On an ongoing basis, we evaluate 
our estimates, including those related to revenue recognition, inventories, income taxes, property plant and equipment, 
impairment of property, plant and equipment and assets held for sale and litigation.  We base our estimates on historical 
experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which 
form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other 
sources.  Results may differ from these estimates due to actual outcomes being different from those on which we based our 
assumptions.  We review these estimates and judgments on an ongoing basis.  We believe the following critical accounting 
policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.  
We also have other policies that we consider key accounting policies, such as our policy regarding revenue recognition to 
OEMs; however, we do not believe these policies require us to make estimates or judgments that are as difficult or subjective 
as our policies described below. 

Revenue Recognition – Distributors 

Our distributors worldwide have broad rights to return products and price protection rights, so we defer revenue 
recognition until the distributor sells the product to their customers.  We reduce product pricing through price protection 
based on market conditions, competitive considerations and other factors.  Price protection is granted to distributors on the 
inventory that they have on hand at the date the price protection is offered.  When we reduce the price of our products, it 
allows the distributor to claim a credit against its outstanding accounts receivable balances based on the new price of the 
inventory it has on hand as of the date of the price reduction.  There is no revenue impact from the price protections.  We also 
grant certain credits to our distributors.  The credits are granted to the distributors on specially identified pieces of the 
distributors’ business to allow them to earn a competitive gross margin on the sale of our products to their end customers.  
The credits are on a per unit basis and are not given to the distributor until they provide documentation of the sale to their end 
customer.  The effect of granting these credits establishes the net selling price from us to our distributors for the product and 
results in the net revenue recognized by us when the product is sold by the distributors to their end customers.  Upon 
shipment, amounts billed to distributors are included as accounts receivable, inventory is relieved, and the sale and the gross 
margin are deferred and are reflected as a current liability until the product is sold by the distributor to their customers.   

Inventories 

Inventories are valued at the lower of cost or market using the first-in, first-out method.  We write down our inventory 
for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of inventory and 
the estimated market value based upon assumptions about future demand and market conditions.  If actual market conditions 
are less favorable than those we projected, additional inventory write-downs may be required.  Inventory impairment charges 
establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later 
suggest that increased carrying amounts are recoverable.  In estimating our reserves for obsolescence, we primarily evaluate 
estimates of demand over a 12-month period and provide reserves for inventory on hand in excess of the estimated 12-month 
demand. 

  25

 
 
 
 
 
 
 
Income Taxes 

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in 
each of the jurisdictions in which we operate.  This process involves estimating our actual current tax exposure together with 
assessing temporary differences resulting from differing treatment of items for tax and accounting purposes.  These 
differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet.  We must 
then assess the likelihood that our deferred tax assets will be recovered from future taxable income within the relevant 
jurisdiction and to the extent we believe that recovery is not likely, we must establish a valuation allowance.  We have not 
provided for a valuation allowance because we believe that it is more likely than not that our deferred tax assets will be 
recovered from future taxable income.  Should we determine that we would not be able to realize all or part of our net 
deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period such 
determination was made.  At March 31, 2006, our gross deferred tax asset was $78.5 million. 

Various taxing authorities in the United States and other countries in which we do business are increasing their scrutiny 
of various tax structures employed by businesses.  Companies of our size and complexity are regularly audited by the taxing 
authorities in the jurisdictions in which they conduct significant operations.  We are currently under audit by the United 
States Internal Revenue Service (“IRS”) for our fiscal years ended March 31, 1998, 1999, 2000 and 2001.  As part of this 
ongoing audit, the IRS has proposed certain adjustments related to positions reflected on these returns.  The IRS has issued 
formal assessments for these adjustments.  We do not agree with these adjustments and are appealing these assessments.  We 
recognize liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based on our estimate of 
whether, and the extent to which, additional tax payments are probable.  We believe that we maintain adequate tax reserves to 
offset any potential tax liabilities that may arise upon final resolution of the pending audit through either settlement or the 
appeals process with the IRS.  The IRS is currently auditing our fiscal years ended March 31, 2002, 2003 and 2004.  We 
believe that we maintain adequate tax reserves to offset any potential tax liabilities that may arise upon these and other audits 
in the United States and other countries in which we do business.  If such amounts ultimately prove to be unnecessary, the 
resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed 
necessary.  If such amounts ultimately prove to be less than an ultimate assessment, a future charge to expense would be 
recorded in the period in which the assessment is determined.   

Property, Plant & Equipment 

Property, plant and equipment are stated at cost.  Major renewals and improvements are capitalized, while maintenance 
and repairs are expensed when incurred.  At March 31, 2006, the carrying value of our property and equipment totaled $660.0 
million, which represents 28.1% of our total assets.  This carrying value reflects the application of our property and 
equipment accounting policies, which incorporate estimates, assumptions and judgments relative to the useful lives of our 
property and equipment.  Depreciation is provided on a straight-line basis over the estimated useful lives of the related assets, 
which range from five to seven years on manufacturing equipment and approximately 30 years on buildings.  

We began production activities at Fab 4 on October 31, 2003.  We began to depreciate the Fab 4 assets as they were 

placed in service for production purposes.  As of March 31, 2006, all of the buildings and supporting facilities were being 
depreciated as well as the manufacturing equipment that had been placed in service.  All manufacturing equipment that was 
not being used in production activities was maintained in projects in process and is not being depreciated until it is placed 
into service since management believes there will be no change to its utility from the present time until it is placed into 
productive service.  The lives to be used for depreciating this equipment at Fab 4 will be evaluated at such time as the assets 
are placed in service.  We do not believe that the temporary idling of such assets has impaired the estimated life or carrying 
values of the underlying assets. 

On March 31, 2005, we changed the classification of Fab 3 from an asset held-for-sale to an asset held-for-future-use.  

Fab 3 had been on the market for over two years, and we had not received any acceptable offers on the facility.  Over that 
period of time, our business had increased significantly and over the next several years we will need to begin planning for 
future wafer fabrication capacity as a larger percentage of Fab 4’s clean room capacity is utilized.  We determined that the 
appropriate action to take was to stop actively marketing the Fab 3 facility and hold it for our future use.  As a result of this 
change in classification, we had to assess the fair value of the Fab 3 asset to determine if any additional impairment charge 
was required upon the change in classification from “held-for-sale” to “held-for-future-use” under SFAS No. 144.  We 
performed a discounted cash flow analysis of the Fab 3 asset based on various financial projections in developing the fair 
value estimate given that it was the best available valuation technique for the asset.  The discounted cash flow analysis 
confirmed the carrying value of the Fab 3 asset at March 31, 2005 was not in excess of its fair value.  If indicators of 
impairment for the Fab 3 assets arise in the future, we will determine if the sum of the estimated undiscounted cash flows 
attributable to the assets in question are less than their carrying value.  If less, we would recognize an impairment loss on the 

  26

 
 
 
 
 
 
excess of the carrying amount of the assets over their respective fair values.  We began to depreciate the Fab 3 asset in April 
2005. 

The estimates, assumptions and judgments we use in the application of our property and equipment policies reflect both 

historical experience and expectations regarding future industry conditions and operations.  The use of different estimates, 
assumptions and judgments regarding the useful lives of our property and equipment and expectations regarding future 
industry conditions and operations, could result in materially different carrying values of assets and results of operations. 

We do not currently hold title to the land on which our Thailand facility resides.  The land is subject to a bankruptcy 

relating to the seller of the land.  We have provided reserves that we estimate will be adequate to obtain full title.  Such 
reserves are set at the estimated fair value of the land.  However, timing of the resolution is difficult to predict and the 
ultimate amount to be paid could change. 

Impairment of Property, Plant and Equipment  

We assess whether indicators of impairment of long-lived assets are present.  If such indicators are present, we determine 

whether the sum of the estimated undiscounted cash flows attributable to the assets in question is less than their carrying 
value.  If less, we recognize an impairment loss based on the excess of the carrying amount of the assets over their respective 
fair values.  Fair value is determined by discounted future cash flows, appraisals or other methods.  If the assets determined to 
be impaired are to be held and used, we recognize an impairment loss through a charge to our operating results to the extent 
the present value of anticipated net cash flows attributable to the asset are less than the asset’s carrying value, which we 
depreciate over the remaining estimated useful life of the asset. We may incur impairment losses, or additional losses on 
already impaired assets, in future periods if factors influencing our estimates change. 

Litigation 

Our current estimated range of liability related to pending litigation is based on the probable loss of claims for which we 

can estimate the amount and range of loss.  Recorded reserves were not significant at March 31, 2006.   

Because of the uncertainties related to both the probability of loss and the amount and range of loss on the pending 

litigation, we are unable to make a reasonable estimate of the liability that could result from an unfavorable outcome.  As 
additional information becomes available, we will assess the potential liability related to our pending litigation and revise our 
estimates.  Revisions in our estimates of the potential liability could materially impact our results of operation and financial 
position.

We operate in one industry segment and engage primarily in the design, development, manufacture and marketing of 
semiconductor products.  We sell our products to distributors and original equipment manufacturers, referred to as OEMs, in 
a broad range of market segments, perform ongoing credit evaluations of our customers and generally require no collateral. 

Our net sales of $927.9 million in fiscal 2006 increased by $81.0 million, or 9.6%, over fiscal 2005, and net sales of 
$846.9 million in fiscal 2005 increased by $147.6 million, or 21.1%, over fiscal 2004.  The increases in net sales in fiscal 
2006 compared to fiscal 2005 and in fiscal 2005 compared to fiscal 2004 resulted primarily from increased demand,

predominantly for our proprietary microcontroller and analog products.  Average selling prices for our products were down 
approximately 4% in fiscal 2006 over fiscal 2005 and approximately 4% in fiscal 2005 over fiscal 2004.  The number of units 
of our products sold was up approximately 14% in fiscal 2006 over fiscal 2005 and approximately 26% in fiscal 2005 over 
fiscal 2004.  The average selling prices and the unit volumes of our sales are impacted by the mix of our products sold and 
overall semiconductor market conditions.  We believe that we have continued to grow our percentage of market share in the 
embedded control market over the last three fiscal years.  Key factors in achieving the amount of net sales during the last 
three fiscal years include: 

• 
• 
• 
• 
• 

continued market share gains 
increasing semiconductor content in our customers’ products 
customers’ increasing needs for the flexibility offered by our programmable solutions 
our new product offerings that have increased our served available market  
increasing demand for our products 

We recognize revenue from product sales upon shipment to OEMs.  Under our shipping terms, legal title passes to the 
customer upon shipment from Microchip.  We have no post shipment obligations.  Distributors worldwide generally have 
broad rights to return products and price protection rights, so we defer revenue recognition until the distributors sell the  
product to their customers.  Upon shipment, amounts billed to distributors are included in accounts receivable, inventory is 
relieved, the sale is deferred and the gross margin is reflected as a current liability until the product is sold by the distributors 
to their customers.

Microcontrollers

Our microcontroller product line represents the largest component of our total net sales.  Microcontrollers and associated 

application development systems accounted for approximately 79.3% of our total net sales in fiscal 2006, approximately 
79.7% of our total net sales in fiscal 2005 and approximately 79.6% of our total net sales in fiscal 2004.   

Net sales of our microcontroller products increased approximately 9.1% in fiscal 2006 compared to fiscal 2005, and 
increased approximately 21.2% in fiscal 2005 compared to fiscal 2004.  The increases in net sales were primarily due to 
increased demand for our microcontroller products in end markets, driven principally by market share gains and those factors 
described above under “Net Sales” at page 27.  The end markets that we serve include the automotive, communications, 
computing, consumer and industrial control markets. 

Historically, average selling prices in the semiconductor industry decrease over the life of any particular product.  The 

overall average selling prices of our microcontroller products have remained relatively constant over time due to the 
proprietary nature of these products.  We have experienced, and expect to continue to experience, moderate pricing pressure 
in certain microcontroller product lines, primarily due to competitive conditions.  We have in the past been able to, and 
expect in the future to be able to, moderate average selling price declines in our microcontroller product lines by introducing 
new products with more features and higher prices.  We may be unable to maintain average selling prices for our 
microcontroller products as a result of increased pricing pressure in the future, which could adversely affect our operating 
results. 

Memory Products

Sales of our memory products accounted for approximately 13.5% of our total net sales in fiscal 2006, approximately 

13.6% of our total net sales in fiscal 2005 and approximately 13.1% of our total net sales in fiscal 2004.

Net sales of our memory products increased approximately 8.9% in fiscal 2006 compared to fiscal 2005, and increased 

approximately 25.6% in fiscal 2005 compared to fiscal 2004, driven primarily by customer demand conditions within the 
Serial EEPROM market, which products comprise substantially all of our memory product net sales. 

Serial EEPROM product pricing has historically been cyclical in nature, with steep price declines followed by periods of 
relative price stability, driven by changes in industry capacity at different stages of the business cycle.  We have experienced, 
and expect to continue to experience, varying degrees of competitive pricing pressures in our Serial EEPROM products.  We 
may be unable to maintain the average selling prices of our Serial EEPROM products as a result of increased pricing pressure 
in the future, which could adversely affect our operating results.  

Analog and Interface Products

Sales of our analog and interface products accounted for approximately 7.2% of our total net sales in fiscal 2006, 6.7% 

of our total net sales in fiscal 2005 and approximately 7.3% of our total net sales in fiscal 2004. 

Net sales of our analog and interface products increased approximately 16.6% in fiscal 2006 compared to fiscal 2005 and 

increased approximately 11.9% in fiscal 2005 compared to fiscal 2004.  The increase in net sales of our analog and interface 
products in these periods were driven primarily by new proprietary design wins, supply and demand conditions within the 
market and our ability to gain market share. 

Analog and interface products can be proprietary or non-proprietary in nature.  Currently, we consider more than half of 

our analog and interface product mix to be proprietary in nature, where prices are relatively stable, similar to the pricing 
stability experienced in our microcontroller products.  The non-proprietary portion of our analog and interface business will 
experience price fluctuations, driven primarily by the current supply and demand for those products.  We may be unable to 
maintain the average selling prices of our analog and interface products as a result of increased pricing pressure in the future, 
which could adversely affect our operating results.  We anticipate the proprietary portion of our analog and interface products 
will increase over time. 

Distribution

Distributors accounted for 65% of our net sales in fiscal 2006 and fiscal 2005, and 64% of our net sales in fiscal 2004. 

Our largest distributor accounted for approximately 14% of our net sales in fiscal 2006, and approximately 13% of our 

net sales in fiscal 2005 and fiscal 2004.  Our two largest distributors together accounted for 25% of our net sales in fiscal 
2006, fiscal 2005 and fiscal 2004. 

Generally, we do not have long-term agreements with our distributors and we, or our distributors, may terminate their 
relationships with us with little or no advanced notice.  The loss of, or the disruption in the operations of, one or more of our 
distributors could reduce our future net sales in a given quarter and could result in an increase in inventory returns.   

At March 31, 2006, distributors were maintaining an average of approximately 2.0 months of inventory of our products.  

Over the past three fiscal years, the months of inventory maintained by our distributors have fluctuated between 
approximately 2.0 months and 2.5 months.  Thus, inventory levels at our distributors are at the low end of the range we have 
experienced over the last three years.  We do not believe that inventory holding patterns at our distributors will materially 
impact our net sales, due to the fact that we recognize revenue based on sell through for all of our distributors. 

Distributors generally have broad-based rights to return product to us.  As revenue on distributor shipments is not 
recognized until the distributors sell our product on to their end customers, distributor returns have no impact on revenue 
recognition. 

We also grant certain credits to our distributors and also offer these distributors price protection.  The credits are granted 

to the distributors on specifically identified pieces of the distributors’ business to allow them to earn a competitive gross 
margin on the sale of our products to their end customers.  The credits are on a per unit basis and are not given to the 
distributor until they provide information regarding the sale to their end customer.  The effect of granting these credits 
establishes the net selling price from us to our distributors for the products and results in the net revenue recognized by us 
when the product is sold by the distributors to their end customers. 

We reduce product pricing through price protection based on market conditions, competitive considerations and other 
factors.  Price protection is granted to distributors on the inventory that they have on hand at the date the price protection is 

  29

 
 
 
 
 
 
 
 
 
 
 
 
 
offered.  When we reduce the selling price of our products, it allows the distributors to claim a credit against its outstanding 
accounts receivables balances based on the new price of the inventory it has on hand as of the date of the price reduction.  
There is no revenue recognition impact from the price protection. 

We do not offer material incentive programs to our distributors.

Our sales to foreign customers have been predominately in Asia and Europe, which we attribute to the manufacturing 
strength in those areas for automotive, communications, computing, consumer and industrial control products.  Americas 
sales include sales to customers in the United States, Canada, Central America and South America.  Sales to customers in 
Asia have increased during the last three fiscal years due to many of our customers transitioning their manufacturing 
operations to Asia and growth in demand from the emerging Asian market. 

Sales to foreign customers accounted for approximately 74% of our net sales in fiscal 2006, 73% of our net sales in fiscal 

2005, and 71% of our net sales in fiscal 2004.  Substantially all of our foreign sales are U.S. dollar denominated. 

Sales to customers in China, including Hong Kong, accounted for approximately 17% of our net sales in fiscal 2006 and 

fiscal 2005 and approximately 14% of our net sales in fiscal 2004.  Sales to customers in Taiwan accounted for 
approximately 10% of our net sales in fiscal 2006 and fiscal 2005.  We did not have sales into any other countries that 
exceeded 10% of our net sales during the last three fiscal years. 

Gross Profit 

Our gross profit was $550.9 million in fiscal 2006, $484.0 million in fiscal 2005 and $350.0 million in fiscal 2004.  

Gross profit as a percent of sales was 59.4% in fiscal 2006, 57.1% in fiscal 2005 and 50.0% in fiscal 2004. 

The most significant factors affecting gross profit percentage over the past three fiscal years were: 

• 

• 

Improvements in capacity utilization and product absorption, which positively affected gross margin by 
$23.0 million in fiscal 2006 compared to fiscal 2005, and by $11.8 million in fiscal 2005 compared to fiscal 
2004. 
$31.8 million in accelerated depreciation and other costs associated with the closure of Fab 1, which negatively 
affected gross margin in fiscal 2004. 

•  Changes in period cost of sales in Fab 3 and Fab 4, our non-operational facilities at certain times during the last 
three fiscal years, which impact gross margin.  Period cost of sales amounted to $5.6 million in fiscal 2006, $3.3 
million in fiscal 2005 and $18.1 million in fiscal 2004. 

•  A one-week unpaid shutdown negatively affecting gross profit by $1.7 million in fiscal 2004.  The shutdown 
occurred in the three months ended September 30, 2003 and had a negative impact on gross profit due to the 
fact that certain fixed costs including depreciation, utilities, property taxes and other ongoing costs continued 
when the factory was shut down.  There were no shutdowns in fiscal 2006 or fiscal 2005.   

Other factors that impacted gross profit percentage in the periods covered by this report include: 

• 

• 

continued cost reductions in wafer fabrication and assembly and test manufacturing such as new manufacturing 
technologies and more efficient manufacturing techniques 
factors impacting the average selling prices of our products

• 

fluctuations in the product mix of proprietary microcontroller and analog products and related Serial EEPROM 
products, and 
inventory write-offs and the sale of inventory that was previously written off. 

During fiscal 2006, we operated at approximately 98% of our Fab 2 capacity, which favorably impacted gross margins 

compared to fiscal 2005.  During fiscal 2005, we operated at approximately 96% of our Fab 2 capacity, which favorably 
impacted gross margins compared to fiscal 2004.  Our utilization of Fab 4’s total capacity is at relatively low levels although 
we are utilizing all of the installed equipment base.  We expect to maintain the current level of capacity utilization at Fab 2 
and Fab 4 during the first quarter of fiscal 2007. 

The process technologies utilized impact our gross margins.  Fab 2 currently utilizes various manufacturing process 
technologies, but predominantly utilizes our 0.5 to 1.0 micron processes.  At March 31, 2006, Fab 4 predominantly utilized 
our 0.5 micron process technology.  We continue to transition products to more advanced process technologies to reduce 
future manufacturing costs.  Since the closure of Fab 1 in June 2003, all of our production has been on 8-inch wafers.  The 
first quarter of fiscal 2004, approximately 80% of our production was on 8-inch wafers. 

Our overall inventory levels were $115.0 million at March 31, 2006, compared to $103.7 million at March 31, 2005 and 
$94.5 million at March 31, 2004.  We maintained 106 days of inventory on our balance sheet at March 31, 2006 compared to 
107 days of inventory at March 31, 2005 and 101 days at March 31, 2004. 

We anticipate that our gross margins will fluctuate over time, driven primarily by the overall product mix of 

microcontroller, analog and interface and memory products and the percentage of net sales of each of these products in a 
particular quarter, as well as manufacturing yields, fixed cost absorption, capacity utilization levels, particularly those at 
Fab 4, and competitive and economic conditions.  

At March 31, 2006, approximately 66% of our assembly requirements were performed in our Thailand facility, 
compared to approximately 70% as of March 31, 2005 and approximately 71% at March 31, 2004.  Contractors located in 
Asia perform the balance of our assembly operations.  Substantially all of our test requirements were performed in our 
Thailand facility over the last three fiscal years.  We believe that the assembly and test operations performed at our Thailand 
facility provide us with significant cost savings when compared to contractor assembly and test costs, as well as increased 
control over these portions of the manufacturing process.   

We rely on outside wafer foundries for a small portion of our wafer fabrication requirements. 

Research and Development (R&D) 

R&D expenses for fiscal 2006 were $94.9 million, or 10.2% of sales, compared to $93.0 million, or 11.0% of sales, for 

fiscal 2005 and $85.4 million, or 12.2% of sales, for fiscal 2004.  We are committed to investing in new and enhanced 
products, including development systems software, and in our design and manufacturing process technologies.  We believe 
these investments are significant factors in maintaining our competitive position.  We expense all R&D costs as incurred.  
R&D expenses include expenditures for labor, depreciation, masks, prototype wafers, and expenses for the development of 
process technologies, new packages, and software to support new products and design environments. 

R&D expenses increased $1.9 million, or 2.0%, for fiscal 2006 over fiscal 2005.  The primary reasons for the dollar 
increase in R&D costs in fiscal 2006 compared to fiscal 2005 was higher labor and recruitment costs as a result of expanding 
our technical resources and increases in bonuses.  R&D expenses increased $7.6 million, or 9.0%, for fiscal 2005 over fiscal 
2004.  The primary reasons for the dollar increase in R&D costs in fiscal 2005 compared to fiscal 2004 was higher labor 
costs as a result of expanding our technical resources and increasing bonuses.   

Selling, General and Administrative 

Selling, general and administrative expenses for fiscal 2006 were $129.6 million, or 14.0% of sales, compared to $111.2 

million, or 13.1% of sales, for fiscal 2005, and $92.4 million, or 13.2% of sales, for fiscal 2004.  Selling, general and 
administrative expenses include salary expenses related to field sales, marketing and administrative personnel, advertising 
and promotional expenditures and legal expenses.  Selling, general and administrative expenses also include costs related to 
our direct sales force and field applications engineers who work in sales offices worldwide to stimulate demand by assisting 
customers in the selection and use of our products.

primary reasons for the dollar increases in selling, general and administrative expenses in fiscal 2006 over fiscal 2005 were 
higher labor costs as a result of expanding our internal resources, increases in bonuses and increases in travel expenses.  
Selling, general and administrative expenses increased $18.8 million, or 20.3%, for fiscal 2005 over fiscal 2004.  The primary

labor costs as a result of expanding our internal resources, increases in bonuses, increases in travel expenses and increases in 
audit and legal services.   

Selling, general and administrative expenses fluctuate over time, primarily due to revenue and operating expense 

investment levels.

Fiscal 2005 

Settlement with U.S. Philips Corporation 

In fiscal 2005, we reached an agreement with U.S. Philips Corporation and Philips Electronics North America Corp. 
(together “Philips”) regarding patent license litigation between Philips and ourselves.  The agreement included dismissal of 
the then pending litigation and the cross-license of certain patents between Philips and Microchip.  We recorded a special 
charge of $21.1 million in the quarter ended June 30, 2004 associated with this matter.  As part of the settlement, we licensed 
certain of our patents related to 8-pin microcontrollers to Philips, and Philips licensed its patents related to I2C serial 
communications to us, each on fully-paid up, non-royalty bearing worldwide licenses.  The definitive agreement related to 
this matter was finalized and executed, and we made a cash payment to Philips during our fiscal quarter ending September 
30, 2004. 

Fiscal 2004 

Fab 1 Closure and Special Charges 

On April 7, 2003, we announced our intention to close our Chandler, Arizona (Fab 1) wafer fabrication facility and 
integrate certain Fab 1 personnel and processes into our Tempe, Arizona (Fab 2) wafer fabrication facility.  We completed 
this integration process during the three-month period ended June 30, 2003.  The closure of Fab 1 and the integration of 
certain Fab 1 personnel into Fab 2 operations resulted in a reduction in force of 207 employees who were either directly 
involved in our manufacturing operations or provided support to Fab 1.  The detail of the charges incurred related to the 
closure of Fab 1 that were included in cost of sales for the three-month period ended June 30, 2003 is as follows (amounts in 
thousands):

For the quarter ended June 30, 2003, operating expense included $1,612,000 of special charges recorded principally for 
contract cancellation, severance and other costs related to the closure of Fab 1 and other actions.  We incurred $865,000 of 
such expenditures during fiscal 2004.  We reversed $747,000 of the special charges recorded in the quarter ended June 30, 
2003 in the quarter ended December 31, 2003 as a result of a favorable outcome in the settlement of a contract cancellation. 

The facility where Fab 1 is located is an integral part of our overall campus in Chandler, Arizona.  Within this same 
facility resides our wafer probe, mask making and other manufacturing related activities.  The accelerated depreciation that 
was taken only related to assets used in the wafer fabrication operations at the facility.  The property, plant and equipment 
that was subject to the accelerated depreciation is reflected in the gross and accumulated depreciation carrying values in the 
property, plant and equipment section of our balance sheet and related footnote disclosures. 

Other Income (Expense) 

Interest income in fiscal 2006 increased from interest income in fiscal 2005 as our average invested balances were at 
higher levels in fiscal 2006 compared to fiscal 2005, and we earned a higher interest rate on our invested balances.  Interest 
income in fiscal 2005 increased from interest income in fiscal 2004 as our average invested balances were at higher levels in 
fiscal 2005 compared to fiscal 2004, and we extended the average maturity term of our invested balances and thus earned a 
higher interest rate on our invested balances. 

Provision for Income Taxes 

Provisions for income taxes reflect tax on our foreign earnings and federal and state tax on our U.S. earnings.  Our 
effective tax rate was 32.5% in fiscal 2006, 22.9% in fiscal 2005 and 22.8% in fiscal 2004, and is lower than statutory rates in 
the United States due primarily to lower tax rates at our foreign locations, R&D tax credits and export sales incentives.  Our 
effective tax rate in fiscal 2006 reflects a $30.6 million tax expense related to the repatriation of $500 million of foreign 
earnings under the American Jobs Creation Act (the “Jobs Act”) that was effective for the third quarter of fiscal 2006 which 
increased our effective tax rate in fiscal 2006 by 8.5%.   

Various taxing authorities in the United States and other countries in which we do business are increasing their scrutiny 
of various tax structures employed by businesses.  Companies of our size and complexity are regularly audited by the taxing 
authorities in the jurisdictions in which they conduct significant operations.  We are currently under audit by the IRS for our 
fiscal years ended March 31, 1998, 1999, 2000 and 2001.  As part of this ongoing audit, the IRS has proposed certain 
adjustments related to positions reflected on these returns.  The IRS has issued formal assessments for these adjustments.  We 
do not agree with these adjustments and are appealing these assessments.  We recognize liabilities for anticipated tax audit 
issues in the United States and other tax jurisdictions based on our estimate of whether, and the extent to which, additional 
tax payments are probable.  We believe that we maintain adequate tax reserves to offset any potential tax liabilities that may 
arise upon final resolution of the pending audit through either settlement or the appeals process with the IRS.  The IRS 
recently began an audit of our fiscal years ended March 31, 2002, 2003 and 2004.  We believe that we maintain adequate tax 
reserves to offset any potential tax liabilities that may arise upon these and other audits in the United States and other 
countries in which we do business.  If such amounts ultimately prove to be unnecessary, the resulting reversal of such 
reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary.  If such 
amounts ultimately prove to be less than any final assessment, a future charge to expense would be recorded in the period in 
which the assessment is determined.   

Our Thailand manufacturing operations currently benefit from numerous tax holidays that have been granted to us by the 

Thailand government based on our investments in property, plant and equipment in Thailand.  Our tax holiday periods in 
Thailand expire at various times beginning in September 2006.  We do not expect the future expiration of any of our tax 
holiday periods in Thailand to have a material impact on our overall tax expense due to other tax holidays and an increase in 
income in other taxing jurisdictions with lower statutory rates.

Liquidity and Capital Resources 

We had $1,285.1 million in cash, cash equivalents and short-term and long-term investments at March 31, 2006, an 
increase of $550.5 million from the March 31, 2005 balance. The increase in cash, cash equivalents and short-term and long-
term investments over this time period is primarily attributable to our cash flows generated from operations and, to a lesser 
extent, from increases in short-term borrowings. 

Net cash provided from operating activities was $437.3 million for fiscal 2006, $352.7 million for fiscal 2005 and $343.1 

million for fiscal 2004. The increase in cash flow from operations was primarily due to increases in net income and changes 
in accounts payable and accrued liabilities. 

Net cash used in investing activities was $136.6 million for fiscal 2006, $370.7 million for fiscal 2005 and 

$267.6 million in fiscal 2004.  The decrease in cash used in investing activities in fiscal 2006 over fiscal 2005 was primarily 
due to changes in our net purchases, sales and maturities of investments.  The increase in cash used in investing activities in 
fiscal 2005 over fiscal 2004 was due to changes in our net purchases, sales and maturities of investments.   

Our level of capital expenditures varies from time to time as a result of actual and anticipated business conditions.  
Capital expenditures were $76.3 million in fiscal 2006, $63.2 million in fiscal 2005 and $63.5 million in fiscal 2004.  The 
primary reasons for the dollar increase in capital expenditures in fiscal 2006 over fiscal 2005 was to fund capital expansion 
activities in our manufacturing operations.  We currently intend to spend approximately $80 million during the next 12 
months to invest in equipment and facilities to maintain, and selectively increase, capacity to meet our currently anticipated 
needs.   

We expect to finance capital expenditures through our existing cash balances and cash flows from operations.  We 
believe that the capital expenditures anticipated to be incurred over the next 12 months will provide sufficient manufacturing 
capacity to meet our currently anticipated needs.   

Net cash provided by financing activities was $195.8 million for fiscal 2006.  Net cash used in financing activities was 

$18.6 million for fiscal 2005 and $24.0 million for fiscal 2004.  Proceeds from the sale of stock, the exercise of stock options 
and employee purchases under our employee stock purchase plan were $95.8 million for fiscal 2006, $47.2 million for fiscal 
2005 and $53.2 million for fiscal 2004.  Cash expended for the repurchase of our common stock was $3.3 million in fiscal 
2006, $68.3 million in fiscal 2005 and $53.9 million in fiscal 2004.  We had short-term borrowings of $269.0 million at 
March 31, 2006 and $45.5 million at March 31, 2005.  The short-term borrowings of $269.0 million at March 31, 2006 relate 
to transactions associated with the repatriation of foreign earnings under the Jobs Act.  During fiscal 2006, we paid down 
$45.5 million in short-term borrowings and initiated new borrowings of $269.0 million.  To complete the repatriation of $500 
million, we initiated the $269.0 million in borrowings, which were collateralized against investments that are held in the 
foreign locations, allowing the investments to reach their normal maturity date.  We presently intend to pay down the short-
term borrowings as those investments mature and new cash is generated in the foreign locations.  The short-term debt is a 
result of repurchase agreements that are in place with two investment firms. 

On March 11, 2004, our Board of Directors authorized the repurchase of 2,500,000 shares of our common stock in the 
open market or in privately negotiated transactions.  As of March 31, 2006, we had repurchased the entire 2,500,000 common 
shares under this authorization for a total of $66.1 million.  On April 22, 2004, our Board of Directors authorized the 
repurchase of up to an additional 2,500,000 shares of our common stock in the open market or in privately negotiated 
transactions.  As of March 31, 2006, we had repurchased 1,004,834 common shares under this authorization for a total of 
$26.6 million.  As of March 31, 2006, all of the purchased shares under both authorizations had been reissued to fund stock 
option exercises and purchases under our employee stock purchase plan.  The timing and amount of any future repurchases 
will depend upon market conditions and corporate considerations.   

On October 28, 2002, we announced that our Board of Directors had approved and instituted a quarterly cash dividend 

on our common stock.  The initial quarterly dividend of $0.02 per share was paid on December 6, 2003 in the amount of 
$4.0 million.  We have continued to pay quarterly dividends and have increased the amount of such dividends on a regular 
basis.  During fiscal 2004, we paid dividends in the amount of $0.113 per share for a total dividend payment of $23.3 million.  
During fiscal 2005, we paid dividends in the amount of $0.208 per share for a total dividend payment of $43.0 million.  
During fiscal 2006, we paid dividends in the amount of $0.57 per share for a total dividend payment of $120.1 million.  On 
April 25, 2006, we declared a quarterly cash dividend of $0.215 per share, which was paid on May 23, 2006, to stockholders 
of record on May 9, 2006 and the total amount of such dividend was $46.0 million.  Our Board is free to change its dividend 
practices at any time and to decrease or increase the dividend paid, or not to pay a dividend, on our common stock on the 
basis of our results of operations, financial condition, cash requirements and future prospects, and other factors deemed 

  34

 
 
 
 
 
 
 
 
relevant by our Board.  Our current intent is to provide for ongoing quarterly cash dividends depending upon market 
conditions and our results of operations. 

We enter into hedging transactions from time to time in an attempt to minimize our exposure to currency rate 
fluctuations.  Although none of the countries in which we conduct significant foreign operations have had a highly 
inflationary economy in the last five years, there is no assurance that inflation rates or fluctuations in foreign currency rates in 
countries where we conduct operations will not adversely affect our operating results in the future.  The hedging transactions 
outstanding at March 31, 2006 were immaterial. 

We believe that our existing sources of liquidity combined with cash generated from operations will be sufficient to meet 

our currently anticipated cash requirements for at least the next 12 months.  However, the semiconductor industry is capital 
intensive.  In order to remain competitive, we must constantly evaluate the need to make significant investments in capital 
equipment for both production and research and development.  We may seek additional equity or debt financing from time to 
time to maintain or expand our wafer fabrication and product assembly and test facilities, or for other purposes.  The timing 
and amount of any such financing requirements will depend on a number of factors, including demand for our products, 
changes in industry conditions, product mix, and competitive factors.  There can be no assurance that such financing will be 
available on acceptable terms, and any additional equity financing would result in incremental ownership dilution to our 
existing stockholders. 

Contractual Obligations 

The following table summarizes our significant contractual obligations at March 31, 2006, and the effect such 
obligations are expected to have on our liquidity and cash flows in future periods.  This table excludes amounts already 
recorded on our balance sheet as current liabilities at March 31, 2006 (dollars in thousands):

(1)  Capital purchase obligations represent commitments for construction or purchases of property, plant and 

equipment.  They are not recorded as liabilities on our balance sheet as of March 31, 2006, as we have not yet 
received the related goods or taken title to the property. 

(2)  Other purchase obligations and commitments include payments due under various types of licenses. 

(3)  Total contractual obligations do not include contractual obligations recorded on the balance sheet as current 

liabilities, or certain purchase obligations as discussed below. 

Purchase orders or contracts for the purchase of raw materials and other goods and services are not included in the table 
above.  We are not able to determine the aggregate amount of such purchase orders that represent contractual obligations, as 
purchase orders may represent authorizations to purchase rather than binding agreements.  For the purpose of this table, 
contractual obligations for purchase of goods or services are defined as agreements that are enforceable and legally binding 
on Microchip and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum 
or variable price provisions; and the approximate timing of the transaction.  Our purchase orders are based on our current 
manufacturing needs and are fulfilled by our vendors with short time horizons.  We do not have significant agreements for 
the purchase of raw materials or other goods specifying minimum quantities or set prices that exceed our expected 
requirements for three months.  We also enter into contracts for outsourced services; however, the obligations under these 
contracts were not significant and the contracts generally contain clauses allowing for cancellation without significant 
penalty.

The expected timing of payment of the obligations discussed above is estimated based on current information.  Timing of 

payments and actual amounts paid may be different depending on the time of receipt of goods or services or changes to 
agreed-upon amounts for some obligations. 

Off-Balance Sheet Arrangements 

As of March 31, 2006, we are not involved in any off-balance sheet arrangements, as defined in Item 3(a)(4)(ii) of SEC 

Regulation S-K. 

Recently Issued Accounting Pronouncements 

During December 2004, the FASB issued SFAS No. 123 (Revised 2004) (“SFAS No. 123R”), Share-Based Payment, a 

revision of SFAS No. 123 and supersedes APB Opinion No. 25 and its related implementation guidance.  The Statement 
focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment 
transactions.  SFAS No. 123R requires a public entity to measure the cost of employee services received in exchange for an 
award of equity instruments based on the grant-date fair value of the award (with limited exceptions).  That cost will be 
recognized over the period during which an employee is required to provide service in exchange for the award.  On March 29, 
2005, the SEC issued Staff Accounting Bulletin No. 107 (“SAB No. 107”), which provides the Staff’s views regarding 
interactions between SFAS No. 123R and certain SEC rules and regulations and provides interpretations of the valuation of 
share-based payments for public companies.  

SFAS No. 123R permits public companies to adopt its requirements using one of two methods:  

(1) A “modified prospective” method in which compensation cost is recognized beginning with the effective date (a) based 

on the requirements of SFAS No. 123R for all share-based payments granted after the effective date and (b) based on the 
requirements of SFAS No. 123 for all awards granted to employees prior to the effective date of SFAS No. 123R that remain 
unvested on the effective date.  

(2) A “modified retrospective” method which includes the requirements of the modified prospective method described 

above, but also permits entities to restate based on the amounts previously recognized under SFAS No. 123 for purposes of pro 
forma disclosures either (a) all prior periods presented or (b) prior interim periods of the year of adoption.  

This statement is effective for the beginning of the first annual reporting period that begins after June 15, 2005.  

Therefore, we will adopt the standard effective April 1, 2006 using the modified prospective method.  As permitted by SFAS 
No. 123, we currently account for share-based payments to employees using the intrinsic value method prescribed in APB 
No. 25 and, as such, generally recognize no compensation cost for employee stock options.  Although we have not completed 
our assessment, we believe the impact on our consolidated financial position or results or operations will be material given 
the current number of outstanding stock options.  The effect on our results of operations of expensing stock options using the 
Black-Scholes-Merton method is presented in the disclosure of pro forma net income and earnings per share in Note 1. SFAS 
No. 123R also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing 
cash flow, rather than as an operating cash flow as required under current literature.  The standard also requires that tax 
benefits must be realized through a reduction of income taxes that would otherwise have been paid before the benefit can be 
recorded.  This requirement will reduce net operating cash flows and may increase net financing cash flows in periods after 
adoption. We cannot estimate what those amounts will be in the future because they depend on, among other things, the form 
of equity compensation, the number of grants and when employees exercise stock options.   

Item 7A.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK  

Our investment portfolio, consisting of fixed income securities and money market funds that we hold on an available-for-

sale basis, was $1,285.1 million as of March 31, 2006, and $728.7 million as of March 31, 2005.  These securities, like all 
fixed income instruments, are subject to interest rate risk and will decline in value if market interest rates increase.  We have 
the ability to hold our fixed income investments until maturity and, therefore, we would not expect to recognize any material 
adverse impact in income or cash flows if market interest rates increase.  The following table provides information about our 
available-for-sale securities that are sensitive to changes in interest rates.  We have aggregated our available-for-sale 
securities for presentation purposes since they are all very similar in nature (dollars in thousands):

We have international operations and are thus subject to foreign currency rate fluctuations.  To date, our exposure related 

to exchange rate volatility has not been significant.  Approximately 99% of our sales are denominated in U.S. dollars.  We 
maintain hedges related to our foreign currency exposure of our net investment in a foreign operation as needed.  There were  
no hedges outstanding as of March 31, 2005.  The amounts of the hedges outstanding as of March 31, 2006 and March 31, 
2004 were immaterial.  If foreign currency rates fluctuate by 15% from the rates at March 31, 2006 and March 31, 2005, the 
effect on our financial position and results of operation would not be material. 

During the normal course of business we are routinely subjected to a variety of market risks, examples of which include, 

but are not limited to, interest rate movements and foreign currency fluctuations, as we discuss in this Item 7A, and 
collectability of accounts receivable.  We continuously assess these risks and have established policies and procedures to 
protect against the adverse effects of these and other potential exposures.  Although we do not anticipate any material losses 
in these risk areas, no assurance can be made that material losses will not be incurred in these areas in the future.

Item 9A.  CONTROLS AND PROCEDURES  

Evaluation of Disclosure Controls and Procedures.  

As of the end of the period covered by this Annual Report on Form 10-K, as required by paragraph (b) of Rule 13a-15 or 

Rule 15d-15 under the Securities Exchange Act of 1934, as amended, we evaluated under the supervision of our Chief 
Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures (as defined in 
Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended). Based on this evaluation, our Chief 
Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective to 
ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 
1934 (i) is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange 
Commission rules and forms, and (ii) is accumulated and communicated to our management, including our Chief Executive 
Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our 
disclosure controls and procedures are designed to provide reasonable assurance that such information is accumulated and 
communicated to our management. Our disclosure controls and procedures include components of our internal control over 
financial reporting. Management’s assessment of the effectiveness of our internal control over financial reporting is 
expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can 
provide only reasonable, but not absolute, assurance that the control system’s objectives will be met.  

Management Report on Internal Control Over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting to 

provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements 
for external purposes in accordance with generally accepted accounting principles.  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 

  37

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 

Management assessed our internal control over financial reporting as of March 31, 2006, the end of our fiscal year.  

Management based its assessment on criteria established in Internal Control – Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission.  Management’s assessment included evaluation of 
such elements as the design and operating effectiveness of key financial reporting controls, process documentation, 
accounting policies, and our overall control environment.  This assessment is supported by testing and monitoring performed 
by our finance organization. 

Based on our assessment, management has concluded that our internal control over financial reporting was effective as 
of the end of the fiscal year to provide reasonable assurance regarding the reliability of financial reporting and the preparation 
of financial statements for external reporting purposes in accordance with generally accepted accounting principles.  We 
reviewed the results of management’s assessment with the Audit Committee of our Board of Directors. 

Our independent registered public accounting firm, Ernst & Young LLP, who also audited the Company’s consolidated 
financial statements, audited management’s assessment and independently assessed the effectiveness of our internal control 
over financial reporting.  Ernst & Young LLP has issued their attestation report, which is included in Part II, Item 9A of this 
Form 10-K. 

Changes in Internal Control over Financial Reporting.  

During the three months ended March 31, 2006, there was no change in our internal control over financial reporting 
identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or Rule 15d-15 that has materially 
affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Attestation Report of Independent Registered Public Accounting Firm 

The Board of Directors and Stockholders of 
 Microchip Technology Incorporated and subsidiaries 

We have audited management’s assessment, included in the accompanying Management Report on Internal Control 
Over  Financial  Reporting,  that  Microchip  Technology  Incorporated  and  subsidiaries  maintained  effective  internal 
control over financial reporting as of March 31, 2006, based on criteria established in Internal Control—Integrated 
Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (the  COSO 
criteria). Microchip Technology Incorporated’s management is responsible for maintaining effective internal control 
over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our 
responsibility  is  to  express  an  opinion  on  management’s  assessment  and  an  opinion  on  the  effectiveness  of  the 
company’s internal control over financial reporting based on our audit.  

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United  States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about 
whether  effective  internal  control  over  financial  reporting  was  maintained  in  all  material  respects.  Our  audit 
included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  evaluating  management’s 
assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such 
other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable 
basis for our opinion.  

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance 
regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in 
accordance  with  generally  accepted  accounting  principles.  A  company’s  internal  control  over  financial  reporting 
includes  those  policies  and  procedures  that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance 
with generally  accepted  accounting principles,  and  that  receipts  and  expenditures of  the  company  are  being  made 
only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3)  provide  reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 
assets that could have a material effect on the financial statements.  

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate.  

In  our  opinion,  management’s  assessment  that  Microchip  Technology  Incorporated  maintained  effective  internal 
control over financial reporting as of March 31, 2006, is fairly stated, in all material respects, based on the COSO 
criteria.  Also,  in  our  opinion,  Microchip  Technology  Incorporated  maintained,  in  all  material  respects,  effective 
internal control over financial reporting as of March 31, 2006, based on the COSO criteria.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the March 31, 2006 consolidated financial statements of Microchip Technology Incorporated and our report 
dated May 17, 2006 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

The Board of Directors and Stockholders of 
 Microchip Technology Incorporated and subsidiaries 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Microchip  Technology  Incorporated  and 
subsidiaries as of March 31, 2006 and 2005, and the related consolidated statements of income, stockholders’ equity, 
and cash flows for each of the three years in the period ended March 31, 2006. These financial statements are the 
responsibility  of  the  company’s  management.  Our  responsibility  is  to  express  an  opinion  on  these  financial 
statements based on our audits.  

We  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United  States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about 
whether  the  financial  statements  are  free  of  material  misstatement.  An  audit  includes  examining,  on  a  test  basis, 
evidence  supporting  the  amounts  and  disclosures  in  the  financial  statements.  An  audit  also  includes  assessing  the 
accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.  

In  our  opinion,  the  consolidated  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the 
consolidated financial position of Microchip Technology Incorporated and subsidiaries at March 31, 2006 and 2005, 
and the consolidated results of their operations and their cash flows for each of the three years in the period ended 
March 31, 2006, in conformity with U.S. generally accepted accounting principles.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States),  the  effectiveness  of  Microchip  Technology  Incorporated’s  internal  control  over  financial  reporting  as  of 
March 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee 
of  Sponsoring  Organizations  of  the  Treadway  Commission  and  our  report  dated  May  17,  2006  expressed  an 
unqualified opinion thereon.

MICROCHIP TECHNOLOGY INCORPORATED AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1. 

SIGNIFICANT ACCOUNTING POLICIES 

Nature of Business 
Microchip develops and manufactures specialized semiconductor products used by its customers for a wide variety 
of embedded control applications.  Microchip’s product portfolio comprises 8- and 16-bit PIC® microcontrollers 
and 16-bit dsPIC® digital signal controllers, which feature on-board Flash (reprogrammable) memory technology.  
In addition, Microchip offers a broad spectrum of high-performance linear, mixed-signal, power management, 
thermal management, battery management and interface devices.  Microchip also makes serial EEPROMs and 
complementary microperipheral products.  Microchip’s synergistic product portfolio targets thousands of 
applications and a growing demand for high-performance designs in the automotive, communications, computing, 
consumer and industrial control markets. 

Principles of Consolidation 
The consolidated financial statements include the accounts of Microchip Technology Incorporated and its wholly-
owned subsidiaries (“Microchip” or the “Company”).  The Company does not have any subsidiaries in which it does 
not own 100% of the outstanding stock.  All of the Company’s subsidiaries are included in the consolidated financial 
statements.  All significant intercompany accounts and transactions have been eliminated in consolidation. 

Revenue Recognition 
The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the 
customer, transfer of title as well as fixed pricing and probable collectability.  The Company recognizes revenue 
from product sales to OEMs upon shipment and records reserves for estimated customer returns.  Distributors 
worldwide generally have broad price protection and product return rights, so the Company defers revenue 
recognition until the distributor sells the product to their customer.  The Company reduces product pricing through 
price protection based on market conditions, competitive considerations and other factors.  Price protection is 
granted to distributors on the inventory that they have on hand at the date the price protection is offered.  When the 
Company reduces the price of its products, it allows the distributor to claim a credit against its outstanding accounts 
receivable balances based on the new price of the inventory it has on hand as of the date of the price reduction.  
There is no revenue impact from the price protections.  The Company also grants certain credits to its distributors.  
The credits are granted to the distributors on specially identified pieces of the distributors’ business to allow them to 
earn a competitive gross margin on the sale of the Company’s products to their end customers.  The credits are on a 
per unit basis and are not given to the distributor until they provide information regarding the sale to their end 
customer.  The effect of granting these credits establishes the net selling price from the Company to its distributors 
for the product and results in the net revenue recognized by the Company when the product is sold by the 
distributors to their end customers.  Upon shipment, amounts billed to distributors are included as accounts 
receivable, inventory is relieved, the sale and the gross margin are deferred and reflected as a current liability until 
the product is sold by the distributor to its customers.  Shipping charges billed to customers are included in net sales, 
and the related shipping costs are included in cost of sales. 

Product Warranty 
The Company generally sells products with a limited warranty related to product quality and a limited 
indemnification of customers against intellectual property infringement claims related to the Company’s products.  
Due to comprehensive product testing, the short time between product shipment and the detection and correction of 
product failures, and a low historical rate of payments on indemnification claims, the accrual based on historical 
activity and the related expense were not significant as of and for the fiscal years presented. 

Advertising Costs 
The Company expenses all advertising costs as incurred.  Advertising costs were not material in the years ended 
March 31, 2006, 2005 and 2004. 

F-6 

 
 
 
 
 
 
 
 
 
 
Research and Development 
Research and development costs are expensed as incurred.  Research and development expenses include 
expenditures for labor, masks, prototype wafers, and expenses for development of process technologies, new 
packages, and software to support new products and design environments. 

Foreign Currency Translation and Forward Contracts 
The Company’s foreign subsidiaries are considered to be extensions of the U.S. Company and any translation gains 
and losses related to these subsidiaries are included in other income and expense.  As the U.S. dollar is utilized as 
the functional currency, gains and losses resulting from foreign currency transactions (transactions denominated in a 
currency other than the subsidiaries’ functional currency) are also included in income.  Gains and losses associated 
with currency rate changes on forward contracts are recorded currently in income.  These gains and losses are 
immaterial to the Company’s financial statements. 

Income Taxes 
As part of the process of preparing its consolidated financial statements, the Company is required to estimate its 
income taxes in each of the jurisdictions in which it operates.  This process involves estimating the Company’s 
actual current tax exposure together with assessing temporary differences resulting from differing treatment of items 
for tax and accounting purposes.  These differences result in deferred tax assets and liabilities, which are included 
within the Company’s consolidated balance sheet.  The Company must then assess the likelihood that its deferred 
tax assets will be recovered from future taxable income and to the extent it believes that recovery is not likely, it 
must establish a valuation allowance.  The Company has not provided for a valuation allowance because 
management currently believes that it is “more likely than not” that its deferred tax assets will be recovered from 
future taxable income.   

Cash and Cash Equivalents 
All highly liquid investments, including marketable securities purchased with a remaining maturity of three months 
or less when acquired are considered to be cash equivalents. 

Short-term and Long-term Investments 
The Company’s investments are classified as available-for-sale.  These investments consist of government agency 
bonds, municipal bonds, state student loan bonds and floating rate securities.  The Company defines short-term 
investments as income yielding securities which can be readily converted to cash and defines long-term investments 
as income yielding securities with maturities of over one year that have unrealized losses attributable to them. The 
Company has the ability to hold its long-term investments until such time as these assets are no longer impaired.  
Such recovery is not expected to occur within the next year.  The Company’s investments are carried at fair value 
with unrealized gains and losses reported in stockholders’ equity. Premiums and discounts are amortized or accreted 
over the life of the related available-for-sale security.  Dividend and interest income are recognized when earned.  
The cost of securities sold is calculated using the specific identification method.   

Allowance for Doubtful Accounts 
The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its 
customers to make required payments, which is included in bad debt expense.  The Company determines the 
adequacy of this allowance by regularly reviewing the composition of its accounts receivable aging and evaluating 
individual customer receivables, considering such customer’s financial condition, credit history and current 
economic conditions.   

Inventories 
Inventories are valued at the lower of cost or market using the first-in, first-out method.  The Company writes down 
its inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the 
cost of inventory and the estimated market value based upon assumptions about future demand and market 
conditions.  If actual market conditions are less favorable than those projected by the Company, additional inventory 
write-downs may be required.  Inventory impairment charges establish a new cost basis for inventory and charges 
are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are 
recoverable.  In estimating reserves for obsolescence, the Company primarily evaluates estimates of demand over a 
12-month period and provides reserves for inventory on hand in excess of the estimated 12-month demand. 

F-7 

 
 
 
 
 
 
 
 
 
Property, Plant and Equipment 
Property, plant and equipment are stated at cost. Major renewals and improvements are capitalized, while 
maintenance and repairs are expensed when incurred.  The Company’s property and equipment accounting policies 
incorporate estimates, assumptions and judgments relative to the useful lives of its property and equipment.  
Depreciation is provided for assets placed in service on a straight-line basis over the estimated useful lives of the 
relative assets, which range from 3 to 30 years.  The Company evaluates the carrying value of its property and 
equipment when events or changes in circumstances indicate that the carrying value of such assets may be impaired.  
Asset impairment evaluations are, by nature, highly subjective. 

Litigation 
The Company’s estimated range of liability related to pending litigation is based on claims for which management 
believes a loss is probable and it can estimate the amount or range of loss.  Because of the uncertainties related to 
both the amount and range of the loss on the pending litigation, the Company is unable to make a reasonable 
estimate of the liability that could result from an unfavorable outcome.  As additional information becomes 
available, the Company will assess the potential liability related to its pending litigation and revise its estimates, if 
necessary.   

Goodwill 
Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net 
identified tangible and intangible assets acquired.  The Company is required to perform an annual impairment 
review, and more frequently under certain circumstances. The goodwill is subjected to this test during the fourth 
quarter of the Company’s fiscal year.  The Company engages primarily in the design, development, manufacture and 
marketing of semiconductor products and, as a result, the Company concluded there is one reporting unit.  The 
impairment review process compares the fair value of the reporting unit to its carrying value.  If the Company 
determines through the impairment process that goodwill has been impaired, the Company will record the 
impairment charge in the statement of income.  As of March 31, 2006, there was no impairment charge related to 
goodwill.   

Impairment of Long-Lived Assets 
The Company assesses whether indicators of impairment of long-lived assets are present.  If such indicators are 
present, the Company determines whether the sum of the estimated undiscounted cash flows attributable to the 
assets in question is less than their carrying value.  If less, the Company recognizes an impairment loss based on the 
excess of the carrying amount of the assets over their respective fair values.  Fair value is determined by discounted 
future cash flows, appraisals or other methods.  If the assets determined to be impaired are to be held and used, the 
Company recognizes an impairment loss through a charge to operating results to the extent the present value of 
anticipated net cash flows attributable to the asset are less than the asset’s carrying value.  The Company would 
depreciate the remaining value over the remaining estimated useful life of the asset. 

Share-Based Compensation 
The Company grants stock options for a fixed number of shares to certain employees and directors with an exercise 
price equal to the fair market value of the shares at the date of grant.  The Company accounts for stock option grants 
in accordance with Accounting Principles Board Opinion No. 25 (“APB No. 25”), “Accounting for Stock Issued to 
Employees” and related Interpretations, and, accordingly, recognizes no compensation expense for the stock option 
grants. 

The Company has granted a limited number of restricted stock units (“RSUs”) to its employees.  The intrinsic value 
of the RSUs is being recorded as compensation expense over the vesting period of the RSUs.  There is $5.7 million 
of deferred share-based compensation on the Company’s balance sheet at March 31, 2006 representing the future 
stock compensation expense to be recorded over the remaining vesting period of the outstanding RSUs.  The 
Company has decided to use RSUs as its primary long-term equity incentive compensation instrument in the future. 

The following table represents the effect on net income and earnings per share (shown in thousands, except for per 
share amounts) if the Company had applied the fair value based method and recognition provisions of SFAS 
No. 123, “Accounting for Stock-Based Compensation,” to share-based employee and director compensation.  For 
purposes of this pro forma disclosure, the value of the options is estimated using a Black-Scholes-Merton option 
pricing model and amortized ratably to expense over the options’ vesting periods.  Because the estimated value is 
determined as of the date of grant, the actual value ultimately realized by the employee may be significantly 
different.

See Note 15 for further discussion of the Company’s equity incentive plans. 

At a meeting held on February 17, 2005, the Compensation Committee of the Board of Directors and the Board of 
Directors of the Company approved the acceleration of the vesting of certain Company stock options with an option 
price of $27.153 per share or greater.  The purpose of the accelerated vesting was to enable the Company to avoid 
recognizing in its income statement compensation expense associated with these options in future periods, upon 
adoption of SFAS No. 123R, “Share-Based Payment” in April 2006.  The pre-tax charge that was avoided amounted 
to approximately $13.7 million and represented the fair value of the unvested awards as of the date of the 
acceleration as determined under SFAS No. 123.  This amount would otherwise have been required to be recognized 
as compensation expense over the vesting period upon adoption of SFAS No. 123R.  As a result of the accelerated 
vesting, approximately 2.3 million option shares or 25.4% of the total number of the outstanding unvested option 
shares as of the date of the acceleration with varying remaining vesting schedules became immediately exercisable.  
In connection with the vesting acceleration, the Company required that any shares received through the exercise of 
the accelerated options not be sold by the option holder until the first to occur of the original vesting date of the 
accelerated option or the termination of the employment of the option holder.  On April 25, 2006, in order to 
alleviate administrative burdens, the Company waived this requirement as to approximately 1.0 million option 
shares held by those employees who are not executive officers, appointed officers or director-level employees of the 
Company.  As of the date of the acceleration, the fair market value of the Company’s common stock was below the 
option price of the accelerated options in all material respects, so no APB No. 25 charges were incurred and future 
potential charges are immaterial. 

Concentrations of Credit Risk 
Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of 
investments in debt securities and trade receivables.  The Company generally places its investments with high-credit  
quality counterparties.  Investments in debt securities with original maturities of greater than six months consist 
primarily of AAA rated financial instruments and counterparties.  The Company’s investments are primarily in 
direct obligations of the United States government or its agencies. 

Concentrations of credit risk with respect to accounts receivable are generally not significant due to the diversity of 
the Company’s customers and geographic sales areas.  The Company had two distributors that accounted for more 
than 10% of its net sales in the year ended March 31, 2006.  The Company sells its products primarily to OEMs and 
distributors in the Americas, Europe and Asia.  The Company performs ongoing credit evaluations of its customers’ 
financial condition and requires collateral, primarily letters of credit, as deemed necessary.  No single end customer 
accounted for 10% or more of the Company’s net sales or accounts receivable balances during the years ended 
March 31, 2006, 2005 and 2004.  See Note 17, Geographic Information, for additional information on the 
Company’s largest distributors. 

Use of Estimates 
The Company has made a number of estimates and assumptions relating to the reporting of assets, liabilities,

statements in conformity with U.S. generally accepted accounting principles.  Actual results could differ from those 
estimates. 

Recently Issued Accounting Pronouncements  
SFAS No. 123 (Revised 2004) (“SFAS No. 123R”), “Share-Based Payment,” is a revision of SFAS No. 123 and 
supersedes APB No. 25 and its related implementation guidance.  The Statement focuses primarily on accounting 
for transactions in which an entity obtains employee services in share-based payment transactions.  SFAS No. 123R 
requires a public entity to measure the cost of employee services received in exchange for an award of equity 
instruments based on the grant-date fair value of the award (with limited exceptions).  That cost will be recognized 
over the period during which an employee is required to provide service in exchange for the award.  On March 29, 
2005, the SEC issued Staff Accounting Bulletin No. 107 (“SAB No. 107”), which provides the Staff’s views 
regarding interactions between SFAS No. 123R and certain SEC rules and regulations and provides interpretations 
of the valuation of share-based payments for public companies.  

SFAS No. 123R permits public companies to adopt its requirements using one of two methods: 

(1) A “modified prospective” method in which compensation cost is recognized beginning with the effective date 
(a) based on the requirements of SFAS No. 123R for all share-based payments granted after the effective date and 
(b) based on the requirements of SFAS No. 123 for all awards granted to employees prior to the effective date of 
SFAS No. 123R that remain unvested on the effective date.  

(2) A “modified retrospective” method which includes the requirements of the modified prospective method 
described above, but also permits entities to restate based on the amounts previously recognized under SFAS No. 123 
for purposes of pro forma disclosures either (a) all prior periods presented or (b) prior interim periods of the year of 
adoption.  

This statement is effective for the beginning of the first annual reporting period that begins after June 15, 2005. 
Therefore, the Company will adopt the standard effective April 1, 2006 using the modified prospective method.  As 
permitted by SFAS No. 123, the Company currently accounts for share-based payments to employees using the 
intrinsic value method prescribed in APB No. 25 and, as such, generally recognizes no compensation cost for 
employee stock options.  Although the Company has not completed its assessment, it believes the impact on its 
consolidated financial position or results or operations will be material given the current number of outstanding stock 
options.  The effect on the Company’s results of operations of expensing stock options using the Black-Scholes-
Merton method is presented in the disclosure of pro forma net income and earnings per share in Note 1.  SFAS 
No. 123R also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a 
financing cash flow, rather than as an operating cash flow as required under current literature.  The standard also 
requires that tax benefits must be realized through a reduction of income taxes that would otherwise have been paid 
before the benefit can be recorded.  This requirement will reduce net operating cash flows and may increase net 
financing cash flows in periods after adoption.

Fiscal 2005 
Settlement with U.S. Philips Corporation 

In fiscal 2005, the Company reached an agreement with U.S. Philips Corporation and Philips Electronics North 
America Corp. (together “Philips”) regarding patent license litigation.  The agreement included dismissal of the then 
pending litigation and the cross-license of certain patents between Philips and the Company.  The Company 
recorded a special charge of $21.1 million in the quarter that ended June 30, 2004 associated with this matter.  
Pursuant to this cross-license, the Company licensed certain of its patents related to 8-pin microcontrollers to 
Philips, and Philips licensed its patents related to I2C serial communications to the Company, each on fully-paid up, 
non-royalty bearing worldwide licenses.  The Company finalized and executed the definitive settlement agreement 
related to this matter and made the cash payment to Philips during the fiscal quarter ending September 30, 2004. 

Fiscal 2004 
Closure of Fab 1 

On April 7, 2003, the Company announced its intention to close its Chandler, Arizona (Fab 1) wafer fabrication 
facility and integrate certain Fab 1 personnel and processes into its Tempe, Arizona (Fab 2) wafer fabrication 
facility.  The Company completed this integration process during the three-month period ended June 30, 2003.  The 
closure of Fab 1 and the integration of certain Fab 1 personnel into Fab 2 operations resulted in a reduction in force 
of 207 employees who were either directly involved in the Company’s manufacturing operations or provided 
support functions to Fab 1.  The detail of the charges incurred related to the closure of Fab 1 that were included in 
cost of sales for the three-month period ended June 30, 2003 is as follows (amounts in thousands): 

Accelerated depreciation for Fab 1 
Fab 1 related charges including severance, 
  material and other costs 
Total charges in cost of sales 

$  30,608 

1,147
$  31,755 

The facility where Fab 1 was located is an integral part of the Company’s overall campus in Chandler, Arizona.  
Within this same facility resides the Company’s wafer probe, mask making and other manufacturing related 
activities.  Consequently it is not possible to abandon or otherwise dispose of this facility.  The accelerated 
depreciation that was taken only related to assets used in the wafer fabrication operations at the facility.  The 
Company has no specific plans for utilizing the space formerly housing the wafer fabrication operations, and intends 
to leave it in an idle state.  The property, plant and equipment that was subject to the accelerated depreciation is 
reflected in the gross and accumulated depreciation carrying values in the property, plant and equipment section of 
the Company’s balance sheet and related footnote disclosures. 

The Company incurred $865,000 of special charges recorded principally for contract cancellation, severance and 
other costs related to the closure of Fab 1 and other actions.

In November 2005, the FASB issued FSP FAS 115-1 and FAS 124-1, “The Meaning of Other-Than-Temporary 
Impairment and Its Application to Certain Investments” (“FSP 115-1”), which provided guidance on determining 
when investments in certain debt and equity securities are considered impaired, whether that impairment is other-
than-temporary, and on measuring such impairment loss. FSP 115-1 was adopted by the Company on January 1, 
2006 and at March 31, 2006, the Company evaluated its investment portfolio, and noted unrealized losses of $16.7 
million were due to fluctuations in interest rates.  Management does not believe any of the unrealized losses 
represented an other-than-temporary impairment based on its evaluation of available evidence as of March 31, 2006.  
The Company’s intent is to hold these investments to such time as these assets are no longer impaired.  For those 
investments not scheduled to mature until after March 31, 2007, such recovery is not anticipated to occur in the next 
year and these investments have been classified as long-term investments.  At March 31, 2006, short-term 
investments consist of $199,491 and long-term investments consist of $520,360. 

The amortized cost and estimated fair value of the available-for-sale securities at March 31, 2006, by maturity, are 
shown below (amounts in thousands).  Expected maturities can differ from contractual maturities because the issuers 
of the securities may have the right to prepay obligations without prepayment penalties, and the Company views its

SHORT-TERM DEBT

The Company had short-term debt of $269.0 million and $45.5 million at March 31, 2006 and March 31, 2005, 
respectively. The short-term debt is a result of repurchase agreements that are in place with two investment 
brokerages. The short-term debt was collateralized with $277.6 million and $47.5 million of available-for-sale 
investments at March 31, 2006 and 2005, respectively. The short-term debt had a weighted average interest rate of 
4.83% and 2.71% as of March 31, 2006 and 2005, respectively.  In fiscal 2006, the borrowings were made to 
complete a $500 million repatriation of foreign earnings under the American Jobs Creation Act. The borrowings 
were collateralized against investments that are held by the Company’s offshore subsidiaries. The Company 
presently intends to pay down the short-term borrowings as the investments mature and also from future offshore 
cash generation. In fiscal 2005, the Company used these borrowings to fund the activity under its stock repurchase 
programs beginning in the second quarter of the year ended March 31, 2005.  There are no covenants associated 
with the repurchase agreements.

Pretax income from foreign operations was $257.8 million, $199.0 million and $136.3 million for the years ended 
March 31, 2006, 2005 and 2004, respectively.  Unremitted foreign earnings that are considered to be permanently 
invested outside the United States, and on which no deferred taxes have been provided, amounted to approximately 
$483.9 million at March 31, 2006.  Should the Company elect in the future to repatriate a portion of the foreign 
earnings so invested, the Company would incur income tax expense on such repatriation, net of any available 
deductions and foreign tax credits.  This would result in additional income tax expense beyond the computed 
expected provision in such periods.   

The American Jobs Creation Act of 2004 (the “Jobs Act”) created a temporary incentive for U.S. corporations to 
repatriate accumulated income earned abroad by providing an 85% dividends-received deduction for certain 
dividends from controlled non-U.S. corporations.  During fiscal 2006, the Company’s Chief Executive Officer 
approved a domestic reinvestment plan, under which the Company repatriated $500 million in earnings outside the 
U.S. pursuant to the Jobs Act.  The Company recorded additional tax expense in fiscal 2006 of approximately 
$30.6 million ($0.14 per diluted common share) related to this decision to repatriate non-U.S. earnings.  This 
repatriation increased the Company’s effective rate for fiscal 2006 by approximately 8.5 percentage points, to 
32.5%.  This increase is reflected as a separate line item in the rate reconciliation table above.

tax liabilities are as follows (amounts in thousands):

Management believes that the Company’s results of future operations will generate sufficient taxable income such 
that it is “more likely than not” that the deferred tax assets will be realized. 

At March 31, 2006, the Company had a net operating loss carryforward for federal income tax purposes of 
approximately $12.8 million, which begins to expire in varying amounts in the years 2020 through 2022.  The net 
operating loss carryforward is attributable to the acquisition of PowerSmart in fiscal 2003.  An analysis of the annual

Revenue Code Section 382.  It was determined that Section 382 will not limit the use of the PowerSmart net 
operating losses in full over the carryover period. 

At March 31, 2006, the Company had recorded credit carryforwards of approximately $12.9 million for foreign tax 
credits and $18.8 million for research and development credits.  The foreign tax credits begin to expire in varying 
amounts in the years ending March 31, 2014 through March 31, 2016, and the research and development credits 
begin to expire in varying amounts in the years ending March 31, 2021 through March 31, 2026.  The Company 
believes that all of its credit carryforwards will be utilized in future periods. 

The Company’s Thailand manufacturing operations currently benefit from numerous tax holidays granted to the 
Company based on its investment in property, plant and equipment in Thailand.  The Company’s tax holiday periods 
in Thailand expire at various times beginning in September 2006.  The Company does not expect the future 
expiration of any of its tax holiday periods in Thailand to have a material impact on its effective tax rate.  The 
aggregate dollar benefits derived from these tax holidays approximated $7.9 million, $11.5 million and 
$45.3 million for the years ended March 31, 2006, 2005 and 2004, respectively.  The benefit the tax holiday had on 
net income per share approximated $0.04, $0.05 and $0.21 for the years ended March 31, 2006, 2005 and 2004, 
respectively.  The reduction in the benefits derived from the Company’s tax holiday in Thailand in the years ended 
March 31, 2005 and March 31, 2006 compared to the year ended March 31, 2004 was a result of changes in the 
Company’s overall international tax structure.  These changes did not have a material impact on the Company’s 
overall effective tax rate. 

The Company is currently under audit by the United States Internal Revenue Service (“IRS”) for its fiscal years 
ended March 31, 1998, 1999, 2000 and 2001.  As part of this ongoing audit, the IRS has proposed certain 
adjustments related to positions reflected on these returns.  The IRS has issued formal assessments for these 
adjustments.  The Company does not agree with these adjustments and is appealing these assessments.  The 
Company recognizes liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based 
on its estimate of whether, and the extent to which, additional tax payments are probable.  The Company believes 
that it maintains adequate tax reserves to offset any potential tax liabilities that may arise upon final resolution of the 
pending audit through either settlement or the appeals process with the IRS.  The IRS recently began an audit of the 
Company’s fiscal years ended March 31, 2002, 2003 and 2004.  The Company believes that it maintains adequate 
tax reserves to offset any potential tax liabilities that may arise upon these and other audits in the United States and 
other countries in which it does business.  If such amounts ultimately prove to be unnecessary, the resulting reversal 
of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed 
necessary.  If such amounts ultimately prove to be less than an ultimate assessment, a future charge to expense 
would be recorded in the period in which the assessment is determined.

CONTINGENCIES

The Company’s assembly and test facility in Thailand is located in Alphatechnopolis Industrial Park near Bangkok 
on land to which the Company expects to acquire title in accordance with its agreement with the landowner.  
Progress towards obtaining full title of the land has been delayed due to a bankruptcy relating to the seller of the 
land.  At this time it is not possible to estimate when, or if, transfer of full title will be completed.  The Company has 
provided reserves that it estimates will be adequate to obtain full title.  Such reserves are set at the estimated fair 
value of the land. 

In the ordinary course of its business, the Company is involved in a limited number of legal actions, both as plaintiff 
and defendant, and could incur uninsured liability in any one or more of them.  Litigation relating to the 
semiconductor industry is not uncommon, and the Company is, and from time to time has been, subject to such 
litigation.  In the Company’s opinion, based on consultation with legal counsel, as of March 31, 2006, the effect of 
such matters will not have a material adverse effect on the Company’s financial position, cash flows or results of 
operations.

STOCKHOLDERS’ EQUITY

Stockholder Rights Plan.  Effective October 11, 1999, the Company adopted an Amended and Restated Preferred 
Shares Rights Agreement (the “Amended Rights Agreement”).  The Amended Rights Agreement amends and 

F-17

 
 
 
 
 
 
 
 
 
 
 
restates the Preferred Share Rights Agreement adopted by the Company as of February 13, 1995 (the “Prior Rights 
Agreement”).  Under the Prior Rights Agreement, on February 13, 1995, the Company’s Board of Directors 
declared a dividend of one right (a “Right”) to purchase one one-hundredth of a share of the Company’s Series A 
Participating Preferred Stock (“Series A Preferred”) for each outstanding share of common stock, $.001 par value, of 
the Company.  The dividend was payable on February 24, 1995 to stockholders of record as of the close of business 
on that date.  The Amended Rights Agreement supersedes the Prior Rights Agreement as originally executed.  Under 
the Amended Rights Agreement, each Right enables the holder to purchase from the Company one one-hundredth of 
a share of Series A Preferred at a purchase price of seventy four dollars and seven cents ($74.07) (the “Purchase 
Price”), subject to adjustment.  Under the Amended Rights Agreement, the rights will become exercisable upon the 
earlier of (i) 10 days following a public announcement that a person or a group of affiliated or associated persons 
has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the Company’s outstanding 
common shares, or (ii) 10 days (or such later date as may be determined by action of the Company’s Board of 
Directors) following the commencement of, or announcement of an intention to make, a tender offer or exchange 
offer the consummation of which would result in a beneficial ownership by a person or group of 15% or more of the 
Company’s outstanding common shares. 

Stock Repurchase Activity.  On August 7, 2002, the Company’s Board of Directors authorized the Company to 
repurchase up to 2,500,000 shares of its common stock in the open market or in privately negotiated transactions.  
As of March 31, 2006, the Company had repurchased the entire 2,500,000 common share authorization for 
$59.3 million.  On March 11, 2004, the Company’s Board of Directors authorized the repurchase of an additional 
2,500,000 shares of its common stock in the open market or in privately negotiated transactions.  As of March 31, 
2006, the Company had repurchased the entire 2,500,000 common share authorization for $66.1 million.  On April 
22, 2004, the Company’s Board of Directors authorized the repurchase of an additional 2,500,000 shares of its 
common stock in the open market or in privately negotiated transactions.  As of March 31, 2006, the Company had 
repurchased 1,004,834 shares under this authorization for $26.6 million.  As of March 31, 2006, all of the purchased 
shares under the authorizations had been reissued to fund stock option exercises and purchases under the Company’s 
employee stock purchase plan.  During the year ended March 31, 2006, the Company purchased 119,934 shares of 
its common stock for $3.3 million.  During the year ended March 31, 2005, the Company purchased 2,184,800 
shares of its common stock for $57.7 million.  During the year ended March 31, 2004, the Company purchased 
2,435,400 shares of its common stock for $63.9 million, of which $10.6 million was not paid until April 2004 and is 
reflected in the March 31, 2004 accounts payable balance.   

14. 

EMPLOYEE BENEFIT PLANS

The Company maintains a contributory profit-sharing plan for its domestic employees meeting certain eligibility and 
service requirements.  The plan qualifies under Section 401(k) of the Internal Revenue Code of 1986, as amended, 
and allows employees to contribute up to 60% of their base salary, subject to maximum annual limitations 
prescribed by the Internal Revenue Service.  The Company shall make a matching contribution of up to 25% of the 
first 4% of the participant’s eligible compensation and may award up to an additional 25% under the discretionary 
match.  All matches are provided on a quarterly basis and require the participant to be an active employee at the end 
of each quarter.  For the fiscal years ended March 31, 2006, 2005 and 2004, the Company contributions to the plan 
totaled $1.5 million, $1.4 million and $1.1 million, respectively.   

The Company’s 2001 Employee Stock Purchase Plan (the “2001 Purchase Plan”) became effective on March 1, 
2002.  The Board of Directors approved the 2001 Purchase Plan in May 2001 and the stockholders approved it in 
August 2001.  Under the 2001 Purchase Plan, eligible employees of the Company may purchase shares of common 
stock at semi-annual intervals through periodic payroll deductions.  The purchase price in general will be 85% of the 
lower of the fair market value of the common stock on the first day of the participant’s entry date into the offering 
period or 85% of the fair market value on the semi-annual purchase date.  Depending upon a participant’s entry date 
into the 2001 Purchase Plan, purchase periods under the 2001 Purchase Plan consist of overlapping periods of either 
24, 18, 12 or 6 months in duration.  2,450,000 shares of common stock have been previously reserved for issuance 
under the 2001 Purchase Plan.  In May 2003, the Board of Directors reserved an additional 975,000 shares of 
common stock for issuance under the 2001 Purchase Plan, which was approved by the stockholders in August 2003.  
In May 2003 and August 2003, the Company’s Board and stockholders, respectively, each approved an annual 
automatic increase in the number of shares reserved under the 2001 Purchase Plan.  The automatic increase took 
effect on January 1, 2005, and on each January 1 thereafter during the term of the plan, and is equal to the lesser of 
(i) 1,500,000 shares, (ii) one half of one percent (0.5%) of the then outstanding shares of the Company’s common 

F-18

 
 
 
 
 
 
 
 
 
stock, or (iii) such lesser amount as is approved by the Company’s Board of Directors.  On January 1, 2006, 
1,058,541 additional shares were reserved under the 2001 Purchase Plan based on the automatic increase.  On 
January 1, 2005, 1,035,863 additional shares were reserved under the 2001 Purchase Plan based on the automatic 
increase.  Since the inception of the 2001 Purchase Plan, 5,519,404 shares of common stock have been reserved for 
issuance and 1,814,452 shares have been issued under this purchase plan. 

During fiscal 1995, a purchase plan was adopted for employees in non-U.S. locations.  Such plan allows for the 
purchase price per share to be 100% of the lower of the fair market value of the common stock at the beginning or 
end of the semi-annual purchase plan period.  Effective May 1, 2006, the Company’s Board approved a purchase 
price per share equal to eighty-five percent (85%) of the lower of the fair market value of the common stock at the 
beginning or end of the semi-annual purchase plan period.  Since the inception of this purchase plan, 348,593 shares 
of common stock have been reserved for issuance and 245,311 shares have been issued under this purchase plan.   

Effective January 1, 1997, the Company adopted a non-qualified deferred compensation arrangement.  This plan is 
unfunded and is maintained primarily for the purpose of providing deferred compensation for a select group of 
highly compensated employees as defined in ERISA Sections 201, 301 and 401.  There are no Company matching 
contributions made under this plan. 

The Company has a management incentive compensation plan which provides for bonus payments, based on a 
percentage of base salary, from an incentive pool created from operating profits of the Company, at the discretion of 
the Board of Directors.  During the years ended March 31, 2006, March 31, 2005 and March 31, 2004, $14.1 
million, $10.2 million and $1.8 million were charged against operations for this plan, respectively. 

The Company also has a plan that, at the discretion of the Board of Directors, provides a cash bonus to all 
employees of the Company based on the operating profits of the Company.  During the years ended March 31, 2006, 
2005 and  2004, $9.4 million, $4.9 million and $2.4 million, respectively, were charged against operations for this 
plan. 

15. 

EQUITY INCENTIVE PLANS

Under the Company’s equity incentive plans (the “Plans”), eligible participants may be granted different types of 
equity incentive awards.  Officers, key employees, non-employee directors and consultants may be granted non-
statutory stock options to purchase shares of common stock at a price not less than 100% of the fair value of the 
option shares on the grant date.  Options granted under the Plans vest over the period determined by the Board of 
Directors at the date of grant, at periods ranging from one year to five years.  The maximum term of options granted 
under the Plans is 10 years.  Historically the Company has gone through its equity compensation grant process 
during the first two weeks of April each year.  At March 31, 2006, there were 13,277,078 shares available for grant 
under the Plans.  The per share weighted average fair value of stock options granted under the Plans for the years 
ended March 31, 2006, 2005 and 2004 was $9.89, $15.82 and $12.06, respectively, based on the date of grant using 
the Black-Scholes-Merton option-pricing model with the following weighted average assumptions: 

Expected life (years) 
Risk-free interest rate 
Volatility 
Dividend yield

67% 
0.97% 

2004 

5.19 
2.90% 
70% 
0.48% 

In light of recent regulatory guidance, the Company refined the assumptions used to estimate the value of employee 
stock options granted in the first quarter of fiscal 2006, and management determined that a blend of implied 
volatility and historical volatility is more reflective of market conditions and a better indicator of expected volatility 
than using purely historical volatility.  Management continued to use this volatility assumption throughout fiscal 
2006. 

Under the Plans, 105,281,645 shares of common stock had been reserved for issuance since the inception of the 
Plans.

At March 31, 2006 and 2005, the number of option shares exercisable was 12,762,774 and 16,014,070, respectively, 
and the weighted-average exercise price of those options was $19.39 and $18.09, respectively. 

The Company received a tax benefit of $29.4 million, $15.3 million and $37.6 million for the years ended March 31, 
2006, 2005 and 2004, respectively, from the exercise of non-qualified stock options and the disposition of stock 
acquired with incentive stock options or through the Company’s employee stock purchase plan.  For financial 
reporting purposes, the tax effect of this deduction is accounted for as a credit to additional paid-in capital rather 
than as a reduction of income tax expense. 

During the year ended March 31, 2006, the Company began issuing Restricted Stock Units (RSUs) under its equity 
incentive plan.  RSUs entitle the holder to receive shares of the Company’s common stock as the RSU vests.  As of 
March 31, 2006, the total amount of unrecognized compensation cost related to nonvested restricted stock awards 
was approximately $5.7 million, and the related weighted-average period over which it is expected to be recognized 
is approximately 2.2 years.  A summary of restricted stock units activity for the year ended March 31, 2006 is as

GEOGRAPHIC INFORMATION

The Company operates in one operating segment and engages primarily in the design, development, manufacture 
and marketing of semiconductor products.  The Company sells its products to distributors and original equipment 
manufacturers (OEMs) in a broad range of market segments, performs on-going credit evaluations of its customers 
and generally requires no collateral.  The Company’s operations outside the United States consist of product 
assembly and final test facilities in Thailand, and sales and support centers and design centers in certain foreign 
countries.  Domestic operations are responsible for the design, development and wafer fabrication of all products, as 
well as the coordination of production planning and shipping to meet worldwide customer commitments.  The 
Thailand assembly and test facility is reimbursed in relation to value added with respect to assembly and test

their territory.  Accordingly, for financial statement purposes, it is not meaningful to segregate sales or operating 
profits for the assembly and test and foreign sales office operations.  Identifiable long-lived assets (consisting of

Sales to unaffiliated customers located outside the United States, primarily in Asia and Europe, aggregated 
approximately 74%, 73% and 71% of consolidated net sales for the years ended March 31, 2006, 2005 and 2004, 
respectively.  Sales to customers in Europe represented 28%, 27% and 28% of consolidated net sales for the years 
ended March 31, 2006, 2005 and 2004, respectively.  Sales to customers in Asia represented 44%, 43% and 41% of 
consolidated net sales for the years ended March 31, 2006, 2005 and 2004, respectively.  Sales into China, including 
Hong Kong, represented 17%, 16% and 14% of consolidated net sales for the years ended March 31, 2006, 2005 and 
2004, respectively.  Sales into Taiwan represented 10% of consolidated net sales for the years ended March 31, 2006 
and 2005.  Sales into any other individual foreign country did not exceed 10% of the Company’s net sales for any of 
the years presented. 

The Company had two distributors who represented more than 10% of its net sales during fiscal 2006, fiscal 2005 
and fiscal 2004.  The Company’s largest distributor accounted for approximately 14% of its net sales and its second 
largest distributor accounted for approximately 11% of net sales in fiscal 2006.  The Company’s largest distributor 
accounted for approximately 13% of its net sales and its second largest distributor accounted for approximately 12% 
of its net sales in fiscal 2005.  The Company’s largest distributor accounted for approximately 13% of its net sales 
and its second largest distributor accounted for approximately 12% of its net sales in fiscal 2004.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amount of cash equivalents approximates fair value because their maturity is less than three months.  
The carrying amount of short-term and long-term investments approximates fair value as the securities are marked 
to market as of each balance sheet date with any unrealized gains and losses reported in stockholders’ equity.  The 
carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the 
short-term maturity of the amounts.  The fair value of short-term debt and lines of credit approximates their carrying 
value as they are estimated by discounting the future cash flows at rates currently offered to the Company for similar 
debt instruments. 

The Company has entered into certain financial instruments in the normal course of business to reduce its exposure 
to fluctuations in foreign exchange rates.  These financial instruments include standby letters of credit and foreign 
currency forward contracts.  When engaging in forward contracts, risks arise from the possible inability of 
counterparties to meet the terms of their contracts and from movements in securities values, interest rates and 
foreign exchange rates.  At March 31, 2006, the Company held contracts with nominal amounts totaling 
$1.6 million, which were entered into and hedged the Company’s foreign currency risk.  The value of the contracts 
is based on quoted market prices.  The contracts matured in April 2006.  At March 31, 2005, there were no foreign 
currency forward contracts outstanding.  Unrealized gains and losses as of the balance sheet dates and realized gains 
and losses for the years ending March 31, 2006, 2005 and 2004 were not material.
