2010 Annual Report and Proxy Statement 

TO OUR STOCKHOLDERS: 

Fiscal year 2010 was a year of significant challenges and opportunity for Microchip brought on by the global economic 
conditions throughout the world.  What started out as a gloomy year filled with the uncertainty of the global economic crisis 
turned out to be a year of significant sequential revenue growth and profitability for Microchip.  For the first time in 
Microchip’s history we achieved double-digit percentage sequential revenue growth in every quarter during a fiscal year, and 
in the fourth quarter of fiscal 2010 we achieved all time records for revenue, non-GAAP gross margin and non-GAAP 
earnings per share.  We firmly believe that the manner in which we handled the 2009 recession has positioned us 
exceptionally well to gain market share in all of our strategic product lines in the future.  As you are well aware, last fiscal 
year (fiscal 2009) was the most difficult year in the history of Microchip due to the global financial crisis.  Our decision not 
to lay off any of our employees during the recession allowed us to keep our new product development activities on track, 
resulting in a record number of new product introductions in fiscal 2010.  Additionally, our customer support activities were 
in full force, allowing our sales team to help our customers design their way out of the recession using Microchip’s 
innovative products.  Our actions during the recession have made Microchip stronger, and positioned us nicely for the future. 

A summary of some of Microchip’s key accomplishments during fiscal year 2010 include: 

  We were one of the few semiconductor companies that remained profitable throughout the global financial crisis.  In 
fiscal 2010, our net sales were up 4.9% over fiscal 2009 and our net income was $216.0 million, which was 22.8% of 
sales. 

  Microchip continued to generate high levels of cash from its operations which allowed us to grow our cash and 

investment balance during fiscal 2010 by $90.8 million, even after paying out a record annual dividend of $249.6 
million.  The quarterly cash dividend payment we made in the fourth quarter of fiscal 2010 was a record 34.1 cents per 
share. 

  We introduced approximately 150 microcontrollers, analog products and memory products.  Today we have over 700 

microcontroller products and over 600 analog products in our portfolio.   

  Based on Semiconductor Industry Association (SIA) data, we gained market share in all of our target markets -- 8-bit and 
16-bit microcontrollers, and analog.  We are continuing to expand our 32-bit microcontroller product offering with 
outstanding market acceptance.  This business is growing at a rapid pace, albeit from a small base. 

  Microchip’s analog products attained new highs in revenue in fiscal 2010 and ended the year with an annual revenue run 
rate of over $125 million (by annualizing the fourth quarter results).  Over the past two years, Microchip was the fastest 
growing diversified analog company in the semiconductor industry. 

  Microchip shipped 160,243 development systems in fiscal 2010, a 17.4% increase over the previous fiscal year.  Every 

quarter in fiscal 2010 set a new record for quarterly development tools shipped.  We believe development tool shipments 
are an excellent leading indicator of the future success of Microchip’s products as a development tool is often the first 
item a customer needs to purchase when beginning their design process with one of our microcontroller products. 

  During fiscal 2010, we announced our agreement to acquire Silicon Storage Technology, Inc. (“SST”) and we closed this 
acquisition on April 8, 2010.  Through this acquisition Microchip gained access to SST’s SuperFlash® technology and 
extensive patent portfolio, which are critical building blocks for advanced microcontrollers.  We expect that the SST 
acquisition will enhance our ability to customize technology variants, thereby adding an advantage over competing 
technologies.  Since completing the acquisition, we have already made significant progress in rationalizing SST’s 
business and expect that the acquisition will significantly add to Microchip’s value proposition to both its customers and 
stockholders. 

 
 
 
 
 
 
 
 
 
 
 
 
  During fiscal 2010, we acquired ZeroG Wireless, Inc. (“ZeroG”), an innovator in low-power embedded Wi-Fi® 

solutions.  ZeroG is a developer of Wi-Fi-certified transceivers and FCC-certified modules which further strengthen 
Microchip’s wireless offerings by enabling embedded designers to easily connect to this ubiquitous networking protocol 
with any 8-, 16- or 32-bit PIC® microcontroller. 

  During fiscal 2010, Microchip successfully integrated and expanded the market position of R&E International, a leading 
provider of analog products addressing the safety and security markets.  We acquired R&E International at the end of 
fiscal 2009. 

  Microchip won the 2010 Arizona Business Leadership Award, and was named to the Phoenix Business Journal’s “Best 

Places to Work in the Valley” for the third consecutive year.  During fiscal 2010, I had the distinct honor of receiving the 
Executive of the Year award in the annual EE times ACE Awards, and I was included in the Phoenix Business Journal’s 
annual list of Most Admired CEOs.  While these awards were bestowed on me, they were possible only because of the 
hard work and extraordinary results created by the global Microchip team and as such, belong to them. 

  Microchip’s products also gained numerous honors for product excellence in fiscal 2010.  The PIC24F16KA eXtreme 
Low Power PIC microcontrollers won the prestigious EDN Innovation Award in the Microcontroller category, and the 
MCP651/2/5 operational amplifiers were finalists in the Analog Signal Path category.  Both of these products were also 
named finalists in the Design News Golden Mousetrap Awards. 

As we begin fiscal year 2011, there remain plenty of challenges in the global economy.  However, we believe we have 
positioned Microchip to gain market share and deliver outstanding financial performance in fiscal 2011.  I want to express 
my sincere appreciation to our customers, stockholders and employees for your ongoing support of Microchip.

Microchip Technology Incorporated ("Microchip") of proxies to be voted at Microchip's 2010 annual meeting of stockholders 
and at any adjournment(s) thereof. 

Our fiscal year begins on April 1 and ends on March 31.  References in this proxy statement to fiscal 2010 refer to the 
12-month period from April 1, 2009 through March 31, 2010, and references to fiscal 2009 refer to the 12-month period from

We anticipate first mailing this proxy statement and accompanying form of proxy on July 12, 2010 to holders of 

Microchip's common stock on June 21, 2010, the Record Date for the annual meeting. 

PROXIES AND VOTING PROCEDURES 

YOUR VOTE IS IMPORTANT.  Because many stockholders cannot attend the annual meeting in person, it is 

necessary that a large number of stockholders be represented by proxy.  Stockholders may have a choice of voting over the 
Internet, by using a toll-free telephone number or by completing a proxy card and mailing it in the postage-paid envelope 
provided.  Please refer to your proxy card or the information forwarded by your bank, broker or other holder of record to see 
which options are available to you.  Under Delaware law, stockholders may submit proxies electronically.  Please be aware that 
if you vote over the Internet, you may incur costs such as telephone and Internet access charges for which you will be 
responsible. 

You can revoke your proxy at any time before it is exercised by timely delivery of a properly executed, later-dated 

proxy (including an Internet or telephone vote if these options are available to you) or by voting by ballot at the annual meeting.  

The method by which you vote will in no way limit your right to vote at the annual meeting if you later decide to attend 

in person.  If your shares are held in the name of a bank, broker or other holder of record, you must obtain a proxy, executed in 
your favor, from the holder of record, to be able to vote at the annual meeting. 

All shares entitled to vote and represented by properly completed proxies received prior to the annual meeting and not 

revoked will be voted at the annual meeting in accordance with the instructions on such proxies.  IF YOU DO NOT INDICATE 
HOW YOUR SHARES SHOULD BE VOTED ON A MATTER, THE SHARES REPRESENTED BY YOUR 
PROPERLY COMPLETED PROXY WILL BE VOTED AS OUR BOARD OF DIRECTORS RECOMMENDS. 

If any other matters are properly presented at the annual meeting for consideration, including, among other things, 
consideration of a motion to adjourn the annual meeting to another time or place, the persons named as proxies and acting 
thereunder will have discretion to vote on those matters according to their best judgment to the same extent as the person 
delivering the proxy would be entitled to vote.  At the date this proxy statement went to press, we did not anticipate that any 
other matters would be raised at the annual meeting.

Stockholders Entitled to Vote 

Stockholders of record at the close of business on the Record Date, June 21, 2010, are entitled to notice of and to vote at the 
annual meeting.  Each share is entitled to one vote on each of the five director nominees and one vote on each other matter 
properly brought before the annual meeting.  On the Record Date, there were 185,894,984 shares of our common stock issued 
and outstanding. 

In accordance with Delaware law, a list of stockholders entitled to vote at the annual meeting will be available at the 
annual meeting on August 20, 2010, and for 10 days prior to the annual meeting at 2355 West Chandler Boulevard, Chandler, 
Arizona, between the hours of 9:00 a.m. and 4:30 p.m., Mountain Standard Time. 

Required Vote 

Quorum, Abstentions and Broker Non-Votes 

The presence, in person or by proxy, of the holders of a majority of the shares entitled to vote at the annual meeting is 
necessary to constitute a quorum at the annual meeting.  Abstentions and broker "non-votes" are counted as present and entitled 
to vote for purposes of determining a quorum.  A broker "non-vote" occurs when a nominee holding shares for a beneficial owner 
(i.e., in "street name") does not vote on a particular proposal because the nominee does not have discretionary voting power with 
respect to that item and has not received instructions from the beneficial owner.  Under the rules of the New York Stock 
Exchange (NYSE), which apply to NYSE member brokers trading in non-NYSE stock, brokers have discretionary authority to 
vote shares on certain routine matters if customer instructions are not provided.  Proposal Two to be considered at the annual 
meeting may be treated as a routine matter.  Consequently, if you do not return a proxy card, your broker may have discretion to 
vote your shares on such matter. 

Election of Directors (Proposal One) 

A plurality of the votes duly cast is required for the election of directors (i.e., the five nominees receiving the greatest 

number of votes will be elected).  Abstentions and broker "non-votes" will not affect the election of directors. 

Ratification of Independent Registered Public Accounting Firm (Proposal Two) 

The affirmative vote of the holders of a majority of the shares of common stock present in person or represented by 
proxy and entitled to vote at the annual meeting is required for ratification of the appointment of Ernst & Young LLP as the 
independent registered public accounting firm of Microchip for the fiscal year ending March 31, 2011.  An abstention will have 
the same effect as voting against this proposal.  Broker "non-votes" are not counted for purposes of approving the ratification of 
our accounting firm, and thus will not affect the outcome of the voting on this proposal. 

Electronic Access to Proxy Statement and Annual Report 

This proxy statement and our fiscal 2010 Annual Report are available at www.microchip.com/annual_reports.  

We will post our future proxy statements and annual reports on Form 10-K on our website as soon as reasonably 
practicable after they are electronically filed with the Securities and Exchange Commission (the "SEC").  All such filings on our 
website are available free of charge.  The information on our website is not incorporated into this proxy statement.  Our Internet 
address is www.microchip.com.

Cost of Proxy Solicitation 

Microchip will pay its costs of soliciting proxies.  Proxies may be solicited on behalf of Microchip by its directors, 

officers or employees in person or by telephone, facsimile or other electronic means.  We may also reimburse brokerage firms 
and other custodians, nominees and fiduciaries for their expenses incurred in sending proxies and proxy materials to beneficial 
owners of Microchip common stock. 

Meetings of the Board of Directors  

THE BOARD OF DIRECTORS 

Our Board of Directors met ten times in fiscal 2010.  During fiscal 2010, each of Mr. Day and Mr. Meyercord attended 

100% of the meetings of the Board of Directors, and Mr. Chapman, Mr. Hugo-Martinez and Mr. Sanghi attended 9 of the 10 
meetings of the Board of Directors.  Each director attended 100% of the meetings of the committees on which such director 
served, other than Mr. Hugo-Martinez who attended 8 of the 9 Compensation Committee meetings.  The Board of Directors has 
a practice of meeting in executive session on a periodic basis without management or management directors (i.e., Mr. Sanghi) 
present.  The Board of Directors has determined that each of Mr. Chapman, Mr. Day, Mr. Hugo-Martinez and Mr. Meyercord is 
an independent director as defined by applicable SEC rules and NASDAQ listing standards.  

Board Leadership Structure  

The Board of Directors believes that Microchip's Chief Executive Officer, Steve Sanghi, is best situated to serve as 

Chairman because he is the director most familiar with Microchip's business and industry, and most capable of effectively 
identifying strategic priorities and leading the discussion and execution of strategy. The Board's independent directors have 
different perspectives and roles in strategic development. In particular, Microchip's independent directors bring experience, 
oversight and expertise from outside the company and the industry, while the Chief Executive Officer brings company-specific 
experience and expertise. The Board of Directors believes that the combined role of Chairman and Chief Executive Officer 
promotes strategy development and execution, and facilitates information flow between management and the Board of 
Directors, which are essential to effective governance. Microchip does not have a lead independent director.  

The Board of Directors and the Board committees oversee risk management in a number of ways. The Audit 

Committee oversees the management of financial and accounting related risks as an integral part of it duties. Similarly, the 
Compensation Committee considers risk management when setting the compensation policies and programs for Microchip's 
executive officers. The Board of Directors and the Audit Committee regularly receive reports on various risk related items 
including risks related to manufacturing operations, intellectual property, taxes, products and employees. The Board and the 
Audit Committee also receive periodic reports on Microchip's efforts to manage such risks through safety measures, insurance 
or self-insurance.  

Communications from Stockholders 

Stockholders may communicate with the Board of Directors or individual members of the Board of Directors, provided 

that all such communication is submitted in writing to the attention of the Secretary at Microchip Technology Incorporated, 
2355 West Chandler Boulevard, Chandler, Arizona 85224-6199, who will then forward such communication to the appropriate 
director or directors. 

Committees of the Board of Directors

Audit Committee 

The responsibilities of our Audit Committee are to appoint, compensate, retain and oversee Microchip's independent 

registered public accounting firm, oversee the accounting and financial reporting processes of Microchip and audits of its 
financial statements, and provide the Board of Directors with the results of such monitoring.  These responsibilities are further 
described in the committee charter.  A copy of the Audit Committee Charter, as last amended on May 13, 2007, is available at 
the Corporate/Investors section under Mission Statement/Corporate Governance on www.microchip.com. 

Our Board of Directors has determined that all members of the Audit Committee are independent directors as defined 

by applicable SEC rules and NASDAQ listing standards.  The Board of Directors has also determined that each of 
Mr. Chapman, Mr. Hugo-Martinez and Mr. Meyercord meet the requirements for being an "audit committee financial expert" as 
defined by applicable SEC rules. 

In fiscal 2005, our Audit Committee adopted a policy with respect to (i) the receipt, retention and treatment of 

complaints received by us regarding questionable accounting, internal accounting controls or auditing matters; (ii) the 
confidential, anonymous submission by our employees of concerns regarding questionable accounting, internal accounting 
controls or auditing matters; and (iii) the prohibition of harassment, discrimination or retaliation arising from submitting 
concerns regarding questionable accounting, internal accounting controls or auditing matters or participating in an investigation 
regarding questionable accounting, internal accounting controls or auditing matters.  This policy, called "Legal Compliance," 
was created in accordance with applicable SEC rules and NASDAQ listing requirements.  A copy of this policy is available at 
the Corporate/Investors section under Mission Statement/Corporate Governance on www.microchip.com. 

Compensation Committee 

Our Compensation Committee has oversight responsibility for the compensation and benefit programs for our 
executive officers and other employees, and for administering our equity incentive and employee stock purchase plans adopted 
by our Board of Directors.  The responsibilities of our Compensation Committee are further described in the committee charter 
as adopted on January 29, 2007.  A copy of the Compensation Committee Charter is available at the Corporate/Investors section 
under Mission Statement/Corporate Governance on www.microchip.com. 

The Board of Directors has determined that the members of our Compensation Committee are independent directors as 

defined by applicable SEC rules and NASDAQ listing standards.  For more information on our Compensation Committee, 
please refer to the "Compensation Discussion and Analysis" at page 13. 

Nominating and Governance Committee 

Our Nominating and Governance Committee has the responsibility of ensuring that our Board is properly constituted to 
be able to meet its fiduciary obligations to our stockholders.  In so doing, the Nominating and Governance Committee identifies 
and recommends director candidates, develops and recommends governance principles, and recommends director nominees to 
serve on committees of the Board of Directors.  The responsibilities of our Nominating and Governance Committee are further 
described in the committee charter which is available at the Corporate/Investors section under Mission Statement/Corporate 
Governance on www.microchip.com.  The Board of Directors has determined that all of the members of the Nominating and 
Governance Committee are independent directors as defined by applicable SEC rules and NASDAQ listing standards.

When considering a candidate for a director position, the Nominating and Governance Committee looks for 

demonstrated character, judgment, relevant business, functional and industry experience, and a high degree of skill.  The 
Nominating and Governance Committee does not have a formal policy with respect to diversity; however, the Board of 
Directors and the Nominating and Governance Committee believe that it is important that the members of the Board of 
Directors represent diverse viewpoints.  Accordingly, the Nominating and Governance Committee considers issues of diversity 
in identifying and evaluating director nominees, including differences in education, professional experience, viewpoints, 
technical skills and individual expertise.  The Nominating and Governance Committee evaluates director nominees 
recommended by a stockholder in the same manner as it would any other nominee.  The Nominating and Governance 
Committee will consider nominees recommended by stockholders provided such recommendations are made in accordance with 
procedures described in this proxy statement under "Requirements, Including Deadlines, for Receipt of Stockholder Proposals 
for the 2011 Annual Meeting of Stockholders; Discretionary Authority to Vote on Stockholder Proposals" at page 33.  We do 
not pay any third party to identify or assist in identifying or evaluating potential nominees for director. 

Attendance at the Annual Meeting of Stockholders 

All directors are encouraged, but not required, to attend our annual meeting of stockholders.  All directors attended our 

2009 annual meeting of stockholders.

REPORT OF THE AUDIT COMMITTEE (1) 

Our Board of Directors has adopted a written charter setting out the purposes and responsibilities of the Audit 
Committee.  The Board of Directors and the Audit Committee review and assess the adequacy of the charter on an annual basis.  
A copy of the Audit Committee Charter, as last amended on May 13, 2007, is available at the Corporate/Investors section under 
Mission Statement/Corporate Governance on www.microchip.com. 

Each of the directors who serves on the Audit Committee meets the independence and experience requirements of the 

SEC rules and NASDAQ listing standards.  What this means is the Microchip Board of Directors has determined that no 
member of the Audit Committee has a relationship with Microchip that may interfere with such member's independence from 
Microchip and its management, and that all members have the required knowledge and experience to perform their duties as 
committee members.  

We have received from Ernst & Young LLP the written disclosure and the letter required by Rule 3526 of the Public 

Company Accounting Oversight Board (Communication with Audit Committees Concerning Independence) and have discussed 
with Ernst & Young LLP their independence from Microchip.  We also discussed with Ernst & Young LLP all matters required 
to be discussed by the Statement on Auditing Standards No. 61, as amended (Professional Standards).  We have considered 
whether and determined that the provision of the non-audit services rendered to us by Ernst & Young LLP during fiscal 2010 
was compatible with maintaining the independence of Ernst & Young LLP. 

We have reviewed and discussed with management the audited annual financial statements included in Microchip's 

Annual Report on Form 10-K for the fiscal year ended March 31, 2010 and filed with the SEC, as well as the unaudited 
financial statements filed with Microchip's quarterly reports on Form 10-Q.  We also met with both management and Ernst & 
Young LLP to discuss those financial statements. 

Based on these reviews and discussions, we recommended to the Board of Directors that Microchip's audited financial 
statements be included in Microchip's Annual Report on Form 10-K for the fiscal year ended March 31, 2010 for filing with the 
SEC. 

By the Audit Committee of the Board of Directors: 

Matthew W. Chapman (Chairman) 

Albert J. Hugo-Martinez 

Wade F. Meyercord 

Director Compensation 

Procedures Regarding Director Compensation 

The Board of Directors sets non-employee director compensation.  Microchip does not pay employee directors for 
services provided as a member of the Board of Directors.  Our program of cash and equity compensation for non-employee 
directors is designed to achieve the following goals: compensation should fairly pay directors for work required for a company 
of Microchip's size and scope; compensation should align directors' interests with the long-term interests of stockholders; 
compensation should be competitive so as to attract and retain qualified non-employee directors; and the structure of the 
compensation should be simple, transparent and easy for stockholders to understand.  Non-employee director compensation is 
typically reviewed once per year to assess whether any adjustment is needed to further such goals.  The Board of Directors has 
not used outside consultants in setting non-employee director compensation. 

(1) The Report of the Audit Committee is not "soliciting" material and is not deemed "filed" with the SEC, and is not incorporated by 
reference into any filings of Microchip under the Securities Act of 1933 or the Securities Exchange Act of 1934, whether made before or after 
the date of this proxy statement and irrespective of any general incorporation language contained in such filings.

Director Fees 

During fiscal 2010, non-employee directors received an annual retainer of $28,500, paid in quarterly installments, 

$3,000 for each meeting attended in person and did not receive any additional amounts for serving as a committee chair.  Also, 
directors did not receive any compensation for telephonic meetings of the Board of Directors or for meetings of committees of 
the Board.   

Equity Compensation 

Under the terms of our 2004 Equity Incentive Plan prior to its amendment on May 5, 2010, each non-employee 

director is automatically granted: 

 

upon the date that the individual first is appointed or elected to the Board of Directors as a non-employee 
director: 

 

 

an option to purchase 6,000 shares of common stock which shall vest as to 1/48th of the shares subject to 
such grant each month following the grant date so as to be 100% vested on the four-year anniversary of 
the grant date, 

that number of restricted stock units ("RSUs") equal to $60,000 divided by the fair market value of our 
common stock which shall vest in equal 25% annual installments on each of the four anniversaries of the 
first business day of the second month of our fiscal quarter in which the grant is made, and 

 

upon the date of our annual meeting, provided that the individual has served as a non-employee director for at 
least three months on that date and has been elected by the stockholders to serve as a member of the Board of 
Directors at that annual meeting, 

 

 

an option to purchase 3,000 shares of common stock which shall vest as to 1/12th of the shares subject to 
such grant each month following the grant date so as to be 100% vested on the one-year anniversary of 
the grant date, and 

that number of RSUs equal to $30,000 divided by the fair market value of our common stock which shall 
vest in equal 50% annual installments on each of the two anniversaries of the first business day of the 
second month of our fiscal quarter in which the grant is made, and 

In addition, upon the date of our 2009 annual meeting, each non-employee director who was elected by the 

stockholders to serve as a member of the Board of Directors at that annual meeting, and had served as such for at least five years 
on that date, received a one-time grant of that number of RSUs equal to $100,000 divided by the fair market value of our 
common stock which shall vest in equal 25% annual installments on each of the four anniversaries of the first business day of 
the second month of our fiscal quarter in which the grant is made.   

All vesting of the above grants is contingent upon the non-employee director maintaining his or her continued status as 

a non-employee director through the applicable vesting date. 

In accordance with the foregoing, on August 14, 2009, each of Mr. Chapman, Mr. Day, Mr. Hugo-Martinez and Mr. 
Meyercord was granted an option to acquire 3,000 shares of common stock at an exercise price of $27.03 per share, an annual 
award of 1,109 RSUs and a one-time award of 3,699 RSUs. 

On May 5, 2010, our Board of Directors approved our amended and restated 2004 Equity Incentive Plan which, among 

other things, would change the equity compensation for our non-employee directors to provide (a) on first appointment as a 
director, an initial grant of $160,000 in RSUs (based on the fair market value of our common stock on the grant date), each 
subject to four-year vesting, and (b) an annual grant of $80,000 in RSUs (based on the fair market value of our common stock 
on the grant date) subject to two-year vesting.  Our Board of Directors no longer receives grants of options to purchase common 
stock under our 2004 Equity Incentive Plan. 

The following table details the total compensation for Microchip's non-employee directors for fiscal 2010.

(1)  The amounts shown in the column labeled Option Awards represent the aggregate grant date fair value of awards made in 

fiscal 2010 computed in accordance with ASC 718 Compensation – Stock Compensation.  In fiscal 2010, each non-employee 
director was granted an option to purchase 3,000 shares of common stock at an exercise price of $27.03 pursuant to our 2004 
Equity Incentive Plan.  Each option vests in 12 equal and successive monthly installments following the grant date.  For 
information on the valuation assumptions made with respect to the foregoing option grants, please refer to the assumptions for 
fiscal years ended March 31, 2010 stated in Note 15, "Equity Incentive Plans" to Microchip's audited financial statements for 
the fiscal year ended March 31, 2010, included in Microchip's Annual Report on Form 10-K filed with the Securities and 
Exchange Commission on June 2, 2010. 

(2)  Mr. Sanghi, our Chairman of the Board, President and Chief Executive Officer, does not receive any additional compensation 

for his services as a member of the Board of Directors. 

Compensation Committee Interlocks and Insider Participation 

The Compensation Committee is currently comprised of Mr. Day (Chair), Mr. Hugo-Martinez and Mr. Meyercord, 

three of our independent directors.  None of Mr. Day, Mr. Hugo-Martinez nor Mr. Meyercord had any related-party transaction 
with Microchip during fiscal 2010 other than service as a director.  In addition, none of such directors has a relationship that 
would constitute a compensation committee interlock under applicable SEC rules.  During fiscal 2010, no Microchip executive 
officer served on the compensation committee (or equivalent) or the board of directors, of another entity whose executive 
officer(s) served either on Microchip's Compensation Committee or Board of Directors. 

CERTAIN TRANSACTIONS 

During fiscal 2010, Microchip had no related-party transactions within the meaning of the applicable SEC rules.   

Pursuant to its charter, the Audit Committee reviews issues involving potential conflicts of interest and reviews and 

approves all related-party transactions as contemplated by NASDAQ and SEC rules and regulations.  The Audit Committee may 
consult with the Board of Directors regarding certain conflict of interest matters that do not involve a member of the Board. 

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE  

Section 16(a) and related rules under the Securities Exchange Act of 1934 require our directors, executive officers and 

stockholders holding more than 10% of our common stock to file reports of holdings and transactions in Microchip stock with 
the SEC and to furnish us with copies of all Section 16(a) forms they file.  Based solely on our review of the copies of such 
forms received by us during fiscal 2010, and written representations from our directors and executive officers that no other 
reports were required, we believe that all Section 16(a) filing requirements applicable to our directors, executive officers and 
stockholders holding more than 10% of our common stock were met for fiscal 2010.

PROPOSAL TWO 

RATIFICATION OF APPOINTMENT OF  
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Audit Committee of our Board of Directors has appointed Ernst & Young LLP, independent registered public 

accounting firm, to audit our consolidated financial statements for the fiscal year ending March 31, 2011.  Ernst & Young LLP 
has audited our financial statements since the fiscal year ended March 31, 2002 and has served as our independent registered 
public accounting firm since June 2001.  The partner in charge of our audit is rotated every five years.  Other partners and non-
partner personnel are rotated on a periodic basis. 

We anticipate that a representative of Ernst & Young LLP will be present at the annual meeting, will have the 

opportunity to make a statement if he or she desires and will be available to respond to appropriate questions.  Stockholder 
ratification of the appointment of Ernst & Young LLP is not required by our Bylaws or applicable law.  However, our Board of 
Directors chose to submit such appointment to our stockholders for ratification.  In the event of a negative vote on such 
ratification, the Audit Committee will reconsider its selection. 

Upon the recommendation of our Audit Committee, the Board of Directors recommends that stockholders vote 

FOR ratification of such appointment.

of our SEC registration statements.  This category also included fees associated with the audit of our internal control over 
financial reporting required by Section 404 of the Sarbanes-Oxley Act of 2002.  The aggregate fees billed or to be billed by 
Ernst & Young LLP in each of the last two fiscal years for such services were $1,058,000 for fiscal 2010 and $967,000 for 
fiscal 2009. 

Audit-Related Fees 

This category includes fees associated with employee benefit plan audits, internal control reviews, accounting 
consultations and attestation services that are not required by statute or regulation.  The aggregate fees billed or to be billed by 
Ernst & Young LLP in each of the last two fiscal years for such services were $36,000 for fiscal 2010 and $0 for fiscal 2009.

no such fees in fiscal 2010 or fiscal 2009.  

Our Audit Committee pre-approves all audit and permissible non-audit services provided by our independent registered 

public accounting firm.  These services may include audit services, audit-related services, tax services and other services.  The 
Audit Committee has adopted a policy for the pre-approval of services provided by our independent registered public 
accounting firm.  Under the policy, pre-approval is generally provided for up to one year, and any pre-approval is detailed as to 
the particular service or category of services and is subject to a specific budget or limit.  The Audit Committee may also pre-
approve particular services on a case-by-case basis.  The Chairman of the Audit Committee has the delegated authority from the 
Audit Committee to pre-approve a specified level of services, and such pre-approvals are then communicated to the full Audit

Committee at its next scheduled meeting.  During fiscal 2010, all audit and non-audit services rendered by Ernst & Young LLP

EXECUTIVE COMPENSATION  

COMPENSATION DISCUSSION AND ANALYSIS 

Overview of the Compensation Program 

The Compensation Committee of the Board of Directors, presently comprised of Mr. Day, Mr. Hugo-Martinez and Mr. 

Meyercord, reviews the performance of our executive officers and makes compensation decisions regarding our executive 
officers.  Our policies for setting compensation for each of our named executive officers (CEO, CFO, and our three most highly 
paid executive officers) are the same as those for the rest of our executive officers.  Our compensation program is a 
comprehensive package designed to motivate the executive officers to achieve our corporate objectives and is intended to be 
competitive and allow us to attract and retain highly qualified executive officers.  In general, the types of compensation and 
benefits provided to our executive officers are similar to those provided to most other Microchip employees, and include salary, 
cash bonuses, RSUs, and other benefits described below.   

Our Executive Compensation Policy and Objectives 

Our compensation policy for executive officers, including our named executive officers, and key employees is based 

on a "pay-for-performance" philosophy.  This "pay-for-performance" philosophy emphasizes variable compensation, primarily 
by placing a large portion of pay at risk.  We believe that this philosophy meets the following objectives: 

 
 
 
 

 
 

rewards performance that may contribute to increased stockholder value, 
attracts, retains, motivates and rewards individuals with competitive compensation opportunities, 
aligns an executive officer's total compensation with our business objectives,  
fosters a team environment among our management that focuses their energy on achieving our financial and 
business objectives consistent with Microchip's "guiding values," 
balances short-term and long-term strategic goals, and 
builds and encourages ownership of our common stock. 

Decisions regarding cash and equity compensation also include subjective determinations and consideration of various 

factors with the weight given to a particular factor varying from time to time and in various individual cases, such as an 
executive officer's experience in the industry and the perceived value of the executive officer's position to Microchip as a whole. 

13 

 
 
 
 
 
 
 
 
 
 
 
 
In response to the adverse global economic conditions which impacted our business in fiscal 2009, we took a number 

of actions to significantly reduce our operating expenses, including significant reductions in compensation for our executive 
officers and other employees.  These actions included: 

 

 
 
 

 

 

a reduction in salary equal to one week without pay in the third quarter of fiscal 2009 which ended 
December 31, 2008, 
a 10% salary reduction for all executive officers effective December 29, 2008, 
a week off without pay in the fourth quarter of fiscal 2009 which ended March 31, 2009, 
no payments under our Executive Management Incentive Compensation Plan, or EMICP, or under our 
Discretionary Management Incentive Compensation Plan, or DMICP, for the third and fourth quarters of 
fiscal 2009, 
no payments to officers or employees under our Employee Cash Bonus Program, or ECBP, for the second, 
third and fourth quarters of fiscal 2009, and 
no matching contributions under our 401(k) plan for the third and fourth quarters of fiscal 2009. 

The above actions continued during fiscal 2010, but as global economic conditions improved these actions were 

modified as follows: 

 

 

 

 

the 10% salary reduction for all executive officers effective December 29, 2008, was reduced to 6.5% 
effective July 13, 2009, reduced to 4% effective October 19, 2009, and full salary was reinstated 
December 14, 2009, 
no payments were made under our EMICP for the first quarter of fiscal 2010 and payments resumed in the 
second fiscal quarter, 
no payments were made to officers or employees under our ECBP for the first, second, and third quarters of 
fiscal 2010  and payments resumed in the fourth fiscal quarter, and 
no matching contributions were made under our 401(k) plan for the first, second, and third quarters of fiscal 
2010 and matching contributions resumed in the fourth fiscal quarter. 

We believe that the overall compensation levels for our executive officers, including our named executive officers, in 

fiscal 2010 were consistent with our "pay-for-performance" philosophy and are commensurate with our fiscal 2010 
performance.  

Executive Compensation Process 

On an annual basis, the Compensation Committee evaluates and establishes the compensation of the executive officers, 

including the named executive officers.  The Compensation Committee seeks input from Mr. Sanghi when discussing the 
performance of, and compensation levels for, the executive officers other than himself.  Mr. Sanghi does not participate in 
deliberations relating to his own compensation.   

The Compensation Committee designs our executive compensation program to be competitive with those of other 

companies in the semiconductor or related industries that are similar to us in number of employees, revenue and capitalization.  
The Compensation Committee determines appropriate levels of compensation for each executive officer based on their level of 
responsibility within the organization, performance, and overall contribution.  After such determination, the Compensation 
Committee makes allocations between long-term and short-term as well as the cash and non-cash elements of compensation.  
Microchip's financial and business objectives, the salaries of executive officers in similar positions with comparable companies 
and individual performance are considered in making these determinations.  If compensation information is reviewed for other 
companies, it is obtained from published materials such as proxy statements, and information gathered from such companies 
directly.  We do not engage consultants to conduct such review process for us. 

The executive officer compensation process begins with consideration of Microchip's overall annual budget for 

employee compensation.  The Compensation Committee considers the budgeted salary data and individual executive officer 
salary increases are determined with the goal of keeping the average executive officer salary increase within the budgeted range 
for all other employees.  In setting annual salaries for executive officers, the Compensation Committee also considers relevant 
industry data but does not target any overall industry percentage level or peer group average. 

14 

 
 
 
 
 
 
 
 
 
 
 
Microchip's annual budget is created as part of Microchip's annual operating plan process under which business and 
financial objectives are initially developed by our executive officers, in conjunction with their respective operating units, and 
then discussed with and approved by our CEO.  These objectives are then reviewed by our Board of Directors and the Board of 
Directors sets the overall financial and business objectives for Microchip on which incentive compensation is based. 

The Compensation Committee sets the compensation of our Chairman, CEO and President, Mr. Sanghi, in the same 

manner as each of our other executive officers.  In particular, the Compensation Committee considers Mr. Sanghi's level of 
responsibility, performance, and overall contribution to the results of the organization.  The Compensation Committee also 
considers the compensation of CEOs of other companies in the semiconductor or related industries that are similar to us in 
number of employees, revenue and capitalization.  Mr. Sanghi participates in the same cash incentive, equity incentive and 
benefit programs as our other executive officers.  For example, his compensation is subject to the same performance metrics 
as our other executive officers under our EMICP and DMICP programs.  The Compensation Committee recognizes that 
Mr. Sanghi's total compensation package is significantly higher than that of our other executive officers and the Compensation 
Committee believes this is appropriate in consideration of Mr. Sanghi's superior leadership of Microchip over a long period of 
time.  In particular, the Compensation Committee believes that Mr. Sanghi's leadership has been key to the substantial revenue 
growth, strong market position and substantial increase in the market value of Microchip since taking Microchip public in 1993, 
and to leading Microchip's strong performance relative to others in the industry in the adverse conditions which impacted the 
semiconductor industry and the global economy in late 2008 and for much of 2009. 

For fiscal 2010, the Compensation Committee reviewed and approved the total compensation package of all of our 

executive officers, including the elements of compensation discussed below, and determined the amounts to be reasonable and 
competitive.   

Elements of Compensation 

Our executive compensation program is currently comprised of four major elements: 

 
 
 
 

annual base salary, 
incentive cash bonuses, 
equity compensation, and 
compensation and employee benefits generally available to all of our employees. 

The retirement benefits and other benefits offered to our executive officers are largely the same as those we provide to 

a broad base of employees.  While our executive officers' level of participation in our management incentive compensation 
plans and equity incentive plans is typically higher than for our non-executive employees, based on the officers' level of 
responsibility and industry experience, the plans in which our executive officers are eligible to participate are very similar to 
those for our other employees.  The Compensation Committee reviews each element of compensation separately and total 
compensation as a whole, other than those benefits which are available to all employees.  The Compensation Committee 
determines the appropriate mix of elements to meet our compensation objectives and to help ensure that we remain competitive 
with the compensation practices in our industry. 

Although our executive officers are entitled to certain severance and change of control benefits (as described below), 

the Compensation Committee does not consider such benefits to be elements of compensation for purposes of annual 
compensation reviews because such benefits may never be paid. 

Base Salaries.  We review the base salaries of our executive officers each year.  When setting base salaries, we review 

the business and financial objectives for Microchip as a whole, as well as the objectives for each of the individual officers 
relative to their respective areas of responsibility.  We may also consider the salaries of executive officers in similar positions 
with comparable companies in the semiconductor industry.  This review encompasses the objectives for both the immediately 
preceding fiscal year and the upcoming fiscal year.   

As a result of our annual review of executive officer salaries in fiscal 2010, we did not make any adjustments due to the 

uncertain economic conditions at the time of the review.  However, in connection with the promotion of our Executive VP, 
Ganesh Moorthy, to the position of Chief Operating Officer effective June 1, 2009, Mr. Moorthy's base salary was increased by 
approximately 5%.  Effective February 22, 2010, we also made an interim adjustment of approximately 2% in the base salary 
for our VP, Security, Microcontroller and Technology Development Division, Stephen V. Drehobl, as part of an incentive 
program to reward certain key employees as business conditions improved in the second half of fiscal 2010.  Other than the 

15 

 
 
 
 
 
 
 
 
 
 
foregoing increases, due to overall economic and industry conditions, we had not increased the base salaries of our CEO and 
other named executives since May 2007 other than in connection with the promotion of our VP of Finance, J. Eric Bjornholt, to 
the position of Chief Financial Officer effective January 1, 2009. 

Incentive Cash Bonuses.  The Compensation Committee sets performance goals which, if met, result in quarterly 

payments to our executive officers under the EMICP.  Executive officers may also receive quarterly payments under the 
DMICP.  The Compensation Committee establishes performance goals which it believes are challenging, require a high level of 
performance and motivate participants to drive shareholder value, but which goals are expected to be achievable in the context 
of business conditions anticipated at the time the goals are set.  When setting the performance goals, the Compensation 
Committee places more emphasis on the overall expected financial performance of Microchip rather than on the achievement of 
any one individual goal.  The Compensation Committee believes that this focus on the overall payout incentivizes outstanding 
performance across the corporation and drives the overall financial success of the corporation.  The Compensation Committee 
uses the DMICP to help achieve the overall objectives of the performance bonus program. 

In fiscal 2010, the quarterly payments under the EMICP for our named executive officers were targeted at an aggregate 
of approximately $283,000 for all such officers as a group.  The aggregate budgeted bonus pool under the various management 
incentive compensation plans is calculated by multiplying the eligible executive officer's bonus target percentage by his or her 
base salary.  Actual payments under the various management incentive plans are predicated on Microchip's quarterly operating 
results and, with respect to the DMICP, a subjective element.  Bonuses under the DMICP are subject to a maximum award of 
$2,500,000 per individual on an annual basis; however, all awards to date have been substantially less than such maximum 
amount. 

Due to the continued economic uncertainty, no targets were set for the EMICP for the first quarter of fiscal 2010.  In 

the second through fourth quarters of fiscal 2010, the following business and financial areas were selected as the basis for 
calculating bonuses under our management incentive compensation plans:  

Total sequential revenue growth 
16-bit sequential revenue growth 
Analog sequential revenue growth 
Gross margin percentage  
(non-GAAP) 
Operating expenses as a percentage of sales 
(non-GAAP) 
Operating income as a percentage of sales 
(non-GAAP) 
Earnings per share (quarterly)

(1)  The EMICP quarterly non–GAAP earnings per share (EPS) targets for fiscal 2010 were $0.20, $0.28, and 

$0.33 for the second through fourth quarters, respectively.  There was no EPS target set or payments made for 
the first quarter of fiscal 2010 due to the uncertain economic conditions existing at the time.  The EPS targets 
(as well as the other targets under the EMICP) are set each quarter by the Compensation Committee and may 
be based on either GAAP or non-GAAP financial results at the discretion of the Compensation Committee.  
The Compensation Committee typically uses non-GAAP information when setting the targets because it 
believes such targets are more useful in understanding our operating results due to the exclusion of non-cash, 
non-recurring  and other special charges. 

Consistent with our "pay-for-performance" philosophy, our CEO and other executive officers received bonuses under 
the EMICP for the second, third and fourth quarters of fiscal 2010 based on our financial performance.  Payments were made 
under the DMICP for the first, third and fourth quarters of fiscal 2010.  There was no EMICP bonus for the first quarter of fiscal 
2010 due to the uncertain economic conditions existing at the time.  For fiscal 2010, the total cash bonus payments under the 
EMICP and the DMICP for our named executive officers, other than our CEO, ranged from $66,810 to $196,504.  In fiscal 
2010, Mr. Sanghi earned an aggregate EMICP bonus of $1,071,388, and an aggregate DMICP bonus of $289,928.  The 
differences in the levels of compensation under these programs for the various executive officers are based upon their relative 
contribution, performance, experience, and responsibility level within the organization.   

16 

 
 
 
 
  
 
 
 
Equity Compensation.  Equity compensation, such as RSUs, constitutes a significant portion of our incentive 
compensation program because we believe that executive officers and key employees should hold a long-term equity stake in 
Microchip to align their collective interests with the interests of our stockholders.  In fiscal 2010, equity grants in the form of 
RSUs were a significant portion of our executive officers' total compensation package.   

We typically make equity compensation grants to executive officers and key employees in connection with their initial 
employment, and we also typically make quarterly evergreen grants of equity to incentivize employees on a continuing basis as 
their initial equity awards vest.  In setting the amount of the equity compensation grants, the estimated value of the grants is 
considered, as well as the intrinsic value of the outstanding equity compensation held by the executive officer, both the unvested 
retention value and the vested amount.  In setting these amounts and any performance goals, the Compensation Committee uses 
its judgment after considering the effect of the overall RSU amounts and the percentage of RSUs granted to executive officers in 
connection with the overall financial results and performance of the corporation.  

The evergreen grants of RSUs for fiscal 2010 were awarded with vesting subject to meeting specified performance 

goals over identified periods.  In fiscal 2010, these performance goals were related to achieving certain levels of operating profit 
over a specified time frame.  Specifically, with respect to the awards made in April 2009, the performance goal was related to 
achieving non-GAAP operating profit of $21 million or more for the three months ended June 30, 2009 in order for the awards 
to vest in full.  Based on the actual operating profit for such period, these awards will vest at 100%.  With respect to the awards 
made in July 2009, the performance goal was related to achieving non-GAAP operating profit for the three months ended 
September 30, 2009 of $10 million or more; with an achievement of $40 million of non-GAAP operating profit necessary for 
full vesting of the award.  Based on the actual operating profit for such period, these awards will vest at 100%.  With respect to 
the awards made in October 2009, the performance goal was related to achieving non-GAAP operating profit for the three 
months ended December 31, 2009 of $30 million or more with an achievement of $60 million of non-GAAP operating profit 
necessary for full vesting of the award.  Based on the actual operating profit for such period, these awards will vest at 100%.  
With respect to the awards made in January 2010, the performance goal was related to achieving non-GAAP operating profit for 
the three months ended March 31, 2010 of $40 million or more with an achievement of $70 million of non-GAAP operating 
profit necessary for full vesting of the award.  Based on the actual operating profit for such period, these awards will vest at 
100%.  The vesting of each of the foregoing awards is subject to the continued service of the officer on the vesting date. 

In addition to the evergreen RSU grants, in January 2010, we made additional RSU grants under the 2004 Equity 

Incentive Plan to recognize Microchip's strong financial performance.  These grants were made with vesting subject to a 
performance goal related to achieving non-GAAP operating profit for the three months ended March 31, 2010 of $40 million or 
more with an achievement of $70 million of non-GAAP operating profit necessary for full vesting of the award.  Based on the 
actual operating profit for such period, these awards will vest at 100%.   

Additionally, certain employees with over ten years of service to Microchip received additional RSU grants under the 

2004 Equity Incentive Plan to help retain and reward such employees for their long-standing service to Microchip.  Three 
executive officers received these special ten year service grants: Steve Sanghi, Rich Simoncic and J. Eric Bjornholt.  These 
grants were made with vesting subject to a performance goal related to achieving non-GAAP operating profit for the three 
months ended March 31, 2010 of $40 million or more with an achievement of $70 million of non-GAAP operating profit 
necessary for full vesting of the award.  Based on the actual operating profit for such period, these awards will vest at 100%. 

Grants of RSUs may also be made in connection with promotions, other changes in responsibilities or in recognition of 

other individual or Microchip developments or achievements.  Grants of RSUs in fiscal 2010 typically were scheduled to vest 
approximately four years from the grant date.  The RSUs were awarded without a purchase price and therefore have immediate 
value to recipients upon vesting.  On March 31, 2010, approximately 51% of our employees worldwide held RSUs or options to 
purchase our common stock.  Since the middle of fiscal 2006, RSUs have been the principal equity compensation vehicle for 
Microchip executive officers and key employees. 

In granting equity compensation awards to executive officers, we consider numerous factors, including: 

 
 
 
 

the individual's position, experience, and responsibilities, 
the individual's future potential to influence our mid- and long-term growth, 
the vesting schedule of the awards, and 
the number and value of awards previously granted.   

17 

 
 
 
 
 
 
 
 
 
 
We do not separately target the equity element of our executive officer compensation programs at a specific percentage 

of overall compensation.  However, overall total compensation is structured to be competitive so that we can attract and retain 
executive officers.  In setting equity award levels, we also take into consideration the impact of the equity-based awards on the 
dilution of our stockholders' ownership interests in our common stock. 

The Compensation Committee grants RSUs to executive officers and current employees on a quarterly basis in an 
attempt to more evenly record its stock-based compensation expense.  Grants of RSUs to new employees are made once per 
month by the Employee Committee at a meeting of such committee.  Microchip does not have any program, plan or practice to 
time grants of RSUs in coordination with the release of material non-public information.  Microchip does not time, nor do we 
plan to time, the release of material non-public information for the purposes of affecting the value of executive compensation.   
See the table under "Grants of Plan-Based Awards for Fiscal Year Ended March 31, 2010" at page 24 for 

information regarding RSUs granted during fiscal 2010 to our named executive officers. 

Stock Ownership Guidelines For Key Employees And Directors.  To help ensure alignment of the interests of our 

management and Board of Directors with those of our stockholders, we have put in place a stock holding policy that applies to 
each member of our management and Board of Directors.  This policy was proposed by our Nominating and Governance 
Committee and ratified by our Board of Directors at its October 24, 2003 meeting.  Under this policy, effective April 1, 2004, 
each of our directors, executive officers, vice presidents and internal director-level employees must maintain a specified 
minimum level of ownership of our stock during their tenure in their respective office or position.  During fiscal 2010, all 
persons subject to this policy were in compliance with its terms. 

Microchip does not permit executive officers to speculate in Microchip stock, which includes a prohibition on short 
selling, buying and selling options (including writing covered calls) or hedging or any type of arrangement that has a similar 
economic effect.  

Other Compensation and Employee Benefits Generally Available to All Employees.  We maintain compensation and 

employee benefits that are generally available to all Microchip employees, including: 

our employee stock purchase plan, 

 
  medical, dental, vision, employee assistance program, flexible spending, and short- and long-term disability 

insurance, accidental death and dismemberment insurance, 
life insurance benefits, 
a 401(k) retirement savings plan,  
an employee cash bonus plan, and 
vacation and paid time off. 

 
 
 
 

Since these programs are generally available to all employees, these forms of compensation are not independently 
evaluated by the Compensation Committee in connection with the annual determination of executive officer compensation. 

Employee Stock Purchase Plan.  Our 2001 Employee Stock Purchase Plan is a Section 423 qualified employee stock 
purchase plan that allows all U.S. employees the opportunity to purchase our common stock through payroll deduction at 85% 
of the fair market value at the lower of the price as of the opening of the two-year offering period or at the end of any six-month 
purchase period.  A significant portion of our international employees have the ability to participate in the 1994 International 
Employee Stock Purchase Plan that allows them the opportunity to purchase our common stock through payroll deduction at 
85% of the fair market value at the lower of the price as of the opening or the end of any six-month offering period. 

Medical, Dental, Vision, Employee Assistance Program, Flexible Spending, Alternative Health Care, Long-Term 
Care, Legal Assistance, and Disability Coverage.  We make medical, dental, vision, employee assistance program, flexible 
spending, alternative health care, long term care, legal assistance, and disability coverage available to all of our U.S. employees 
through our active benefit plans.  Under these generally available plans, our named executive officers are eligible to receive 
between $1,000 and $7,500 per month in long-term disability coverage depending on which plan they elect.  Short-term 
disability coverage is provided which allows for 100% of base salary to be paid for six months in the event of disability.  
Accidental death and dismemberment insurance with a benefit of one times the executive's annual salary is provided by 
Microchip.  Since all of our U.S. employees participate in this plan on a non-discriminatory basis, the value of these benefits to 
our named executive officers is not required to be included in the Summary Compensation Table on page 22 pursuant to SEC 
rules and regulations. 

18 

 
 
 
 
 
 
 
 
 
 
Life Insurance.  In fiscal 2010, we provided life insurance coverage to our named executive officers in the amount up 

to one and a half times the executive's annual salary (up to a maximum of $500,000).  The named executive officers may 
purchase supplemental life insurance at their own expense. 

401(k).  We maintain a 401(k) plan for the benefit of all of our U.S. employees to allow our employees to save for 

retirement.  We contribute to our 401(k) plan each year based on our profitability during the year, subject to maximum 
contributions and other rules prescribed by Federal law governing such plans.  Our named executive officers are permitted to 
participate in the plans to the same extent as our other U.S. employees.  In light of the continued economic uncertainty which 
impacted our business in the first part of fiscal 2010, no discretionary matching contributions were made for the first, second or 
third quarters of fiscal 2010 and we eliminated any required matching contribution effective January 1, 2009. 

Employee Cash Bonus Plan.  All of our employees worldwide participate in our ECBP.  This cash bonus plan can 

award each eligible employee with a target of two and one-half days of pay, calculated on base salary, every quarter, if certain 
operating profitability objectives are achieved.  The pay-out is adjusted based on actual quarterly operating results.  During 
fiscal 2010, bonus awards were paid out at 40% for the second quarter, 100% for the third quarter, and 200% for the fourth 
quarter of fiscal 2010.  Under such program, for fiscal 2010, our named executive officers received payments ranging from 
$5,694 to $8,417, and our CEO received $17,404.  

Vacation and Paid Time-Off Benefits.  We provide vacation and other paid holidays to all of our employees, including 

our named executive officers.  We believe our vacation and holidays are comparable to others in the industry. 

Non-Qualified Deferred Compensation Plan.  We maintain a non-qualified deferred compensation plan for certain 

employees, including our named executive officers, who receive compensation in excess of the 401(k) contribution limits 
imposed under the Internal Revenue Code and desire to defer more compensation than they would otherwise be permitted under 
a tax-qualified retirement plan, such as our 401(k) plan.  Microchip does not make contributions to this non-qualified deferred 
compensation plan.  This plan allows our executive officers to make pre-tax contributions to this plan which would be fully 
taxed to the executive officers after the executive officer's termination of employment with Microchip. 

We do not have pension plans or other retirement plans for our named executive officers or our other U.S. employees. 

Employment Contracts, Termination of Employment and Change of Control Arrangements  We do not have 

employment contracts with our CEO, CFO or any of our executive officers, nor agreements to pay severance on involuntary 
termination (other than as stated in the change of control agreements below) or upon retirement.  Our CEO, CFO, and our 
executive officers have entered into change of control agreements with us.   

The change of control agreements were designed to help ensure the continued services of our key executive officers in 

the event that a change of control of the company is effected, and to assist our key executive officers in transitioning from the 
company if as a result of a change of control, they lose their positions.  We believe that the benefits provided by these 
agreements help to ensure that our management team will be incentivized to remain employed with Microchip during a change 
of control.  Capitalized terms used herein and not defined shall have the meanings set forth in the change of control agreements.  
Additionally, our 2004 Equity Incentive Plan has a change of control provision which provides that any successor company 
shall assume each outstanding award or provide an equivalent substitute award; however, if the successor fails to do so, vesting 
of awards shall accelerate.  The Compensation Committee considered prevalent market practices in determining the severance 
amounts and the basis for selecting the events triggering payment in the agreements. 

With respect to our CEO, CFO and VP of Worldwide Sales, if the executive officer's employment terminates for 

reasons other than Cause within the Change of Control Period, the executive officer will be entitled to receive severance 
benefits consisting of the following primary components: 

 

 

a one-time payment of his base salary in effect immediately prior to the Change of Control or termination 
date, whichever is greater, for the following periods: (1) in the case of the CEO, two years; (2) in the case of 
the CFO and the VP of Worldwide Sales, one year; and 
a one-time payment of his bonuses for which he was or would have been eligible in the year in which the 
Change of Control occurred or for the year in which termination occurred, whichever is greater, for the 
following periods:  (1) in the case of the CEO, two years; (2) in the case of the CFO and the VP of Worldwide 
Sales, one year; and 

19 

 
 
 
 
 
 
 
 
 
 
 

 

a continuation of medical and dental benefits (subject to any required employee contributions) for the 
following periods: (1) in the case of the CEO, two years; (2) in the case of the CFO and VP of Worldwide 
Sales, one year; provided in each case that such benefits would cease sooner if and when the executive officer 
becomes covered by the plans of another employer; and  
a payment to cover any excise tax that may be due under Section 4999 of the Code, if the payments provided 
for in the change of control agreement constitute "parachute payments" under Section 280G of the Code and 
the value of such payments is more than three times the executive officer's "base amount" as defined by 
Section 280G(b)(3) of the Code. 

With respect to our CEO, the CFO and the VP of Worldwide Sales, immediately prior to a Change of Control 

(regardless of whether the executive officer's employment terminates), all equity compensation held by the executive officer 
shall become fully vested.  

With respect to our executive officers other than the CEO, the CFO and the VP of Worldwide Sales, if the executive 
officer terminates his employment for Good Reason, or the executive's employment is terminated for reasons other than Cause 
within the Change of Control Period, the executive officer will be entitled to receive severance benefits consisting of the 
following primary components: 

 

 

 

 

a one-time payment of his base salary in effect immediately prior to the Change of Control or termination 
date, whichever is greater, for one year, and 
a one-time payment of his bonuses for which he was or would have been eligible in the year in which the 
Change of Control occurred or for the year in which termination occurred, whichever is greater, for one year, 
and 
a continuation of medical and dental benefits (subject to any required employee contributions) for one year 
(provided in each case that such benefits would cease sooner if and when the executive officer becomes 
covered by the plans of another employer), and 
a payment to cover any excise tax that may be due under Section 4999 of the Code, if the payments provided 
for in the change of control agreement constitute "parachute payments" under Section 280G of the Code and 
the value of such payments is more that three times the executive officer's "base amount" as defined by 
Section 280G(b)(3) of the Code. 

With respect to our executive officers other than the CEO, the CFO and the VP of Worldwide Sales, immediately upon 

termination during the Change of Control Period other than for Cause, all equity compensation held by the executive officer 
shall become fully vested. 

The following table sets forth the aggregate dollar value of payments, to the extent calculable, in the event of a 

termination of a named executive officer on March 31, 2010, the last business day of our last completed fiscal year.

(4)  The change of control payment includes an amount equal to twice the annual salary of the executive plus a bonus equal to 
two times the targeted annual amount payable to such executive under our management incentive compensation plans and 
employee cash bonus plan. 

(5)  The change of control payment includes an amount equal to one times the annual salary of the executive plus a bonus equal 

to the targeted annual amounts payable to such executive under our management incentive compensation plans and employee 
cash bonus plan. 

Performance-Based Compensation and Financial Restatement 

To date, Microchip has not experienced a financial restatement and has not considered or implemented a policy 

regarding retroactive adjustments to any cash or equity-based incentive compensation paid to its executive officers and other 
employees where such payments were predicated upon the achievement of certain financial results that would subsequently be 
the subject of a restatement. 

Tax Deductibility 

Section 162(m) of the Code disallows a corporate income tax deduction for executive compensation paid to our named 

executive officers in excess of $1,000,000 per year, unless that income meets permitted exceptions.  In order to enhance our 
ability to obtain tax deductions for executive compensation, our stockholders approved the EMICP at our 2006 annual meeting.  
This allows us to seek to have such compensation under our EMICP qualify as performance-based compensation under Section 
162(m).  Additionally, our 2004 Equity Incentive Plan allows for the granting of performance-based awards such as RSUs.  To 
the extent that we grant awards with such performance-based limitations, we would expect them to qualify as performance-based 
awards for purposes of 162(m).   

To maintain flexibility in compensating Microchip's executive officers in a manner designed to promote varying 

corporate goals, it is not the policy of the Compensation Committee that executive compensation must be tax deductible.  We 
intend to review the deductibility of executive officer compensation from time to time to determine whether any additional 
actions are advisable to obtain deductibility.   

Conclusion 

We believe that our executive team provided outstanding service to Microchip in fiscal 2010.  We will work to assure 

that the executive compensation programs continue to meet Microchip's strategic goals as well as the overall objectives of the 
compensation program.

(1)  Individual awards under our EMICP are made quarterly and are not stated in terms of a threshold or maximum amount for an 

award period.  The EMICP does provide that the maximum amount payable to any participant is $2.5 million for any fiscal year. 

(2)  Represents RSUs granted under Microchip's 2004 Equity Incentive Plan. 
(3)  This column shows the full grant date fair value of RSU awards granted to the named executives in fiscal 2010.  Generally, the 

full grant date fair value is the amount that Microchip would expense in its financial statements over the award's vesting 
schedule. 

(4)  This annual target represents the percentage of the executive officer's base salary reflected in dollar terms targeted under 

Microchip's EMICP. 

Microchip's DMICP. 

(5)    This annual target represents the percentage of the executive officer's base salary reflected in dollar terms targeted under 

(6)  Microchip's ECBP annual target is based on 2.5 days of base salary per quarter, or on an annual basis, two weeks of the 

executive officer's annual base salary. 

Summary Compensation Table and Grants of Awards Table Discussion 

Based on the data stated in the Summary Compensation Table, the level of salary, bonus and non-equity incentive plan 
compensation in proportion to total compensation ranged from approximately 29% to 40% for our named executive officers in 
fiscal 2010.  See the "Compensation Discussion and Analysis" section of this proxy statement for further discussion of overall 
compensation and how compensation is determined. 

We do not have employment contracts with our named executive officers, nor agreements to pay severance on 

involuntary termination (other than as stated in the change of control agreements discussed above under the heading 
"Employment Contracts, Termination of Employment and Change of Control Arrangements") or retirement. 

For a discussion of the material terms of the awards listed in the Grants of Awards Table, see our discussion of the 

equity awards and incentive cash bonuses in the "Compensation Discussion and Analysis" section of this proxy statement under 
the headings "Incentive Cash Bonuses," "Equity Compensation," and "Employee Cash Bonus Plan." 

Microchip has not repriced any stock options or made any material modifications to any equity-based awards during 

the last fiscal year.

Non-Qualified Deferred Compensation for Fiscal Year 2010 

All of our U.S. employees in director-level and above positions, including our executive officers, are eligible to defer a 
portion of their salary and cash bonuses into our Non-Qualified Deferred Compensation Plan, or the Deferred Compensation 
Plan.  Pursuant to the Deferred Compensation Plan, eligible employees can defer up to 50% of their base salary and/or cash 
bonuses.  In general, deferral elections are made prior to January of each year for amounts to be earned in the upcoming year.  
Participants may invest amounts in various funds available under the Deferred Compensation Plan (in general, any of those funds 
traded on a nationally recognized exchange).  Plan earnings are calculated by reference to actual earnings of mutual funds or 
other securities chosen by individual participants.  

Except for a change in control or certain unforeseeable emergencies (as defined under the Deferred Compensation Plan), 

benefits under the plan will not be distributed until a "distribution event" has occurred.  The distribution event occurs 
upon termination of employment.  

We incur incidental expenses for administration of the Deferred Compensation Plan, and the receipt of any tax benefit we 

might obtain based on payment of a participant's compensation is delayed until funds (including earnings or losses on the 
amounts invested pursuant to the plan) are eventually distributed.  We do not pay any additional compensation or guarantee 
minimum returns to any participant in the Deferred Compensation Plan. 

The following table shows the non-qualified deferred compensation activity for each named executive officer for the 

fiscal year ended March 31, 2010.

(1)  Beginning January 1, 2005, the shares authorized for issuance under our 2001 Employee Stock Purchase Plan are 

subject to an annual automatic increase equal to the lesser of (i) 1,500,000 shares, (ii) one-half of one percent (0.5%) of 
the then outstanding shares of our common stock, or (iii) such lesser amount as is approved by our Board of Directors.  
Beginning January 1, 2007, the shares authorized for issuance under our 1994 International Employee Stock Purchase 
Plan, or the IESPP, are subject to an annual automatic increase of equal to one-tenth of one percent (0.10%) of the then 
outstanding shares of our common stock. 

(2)  Includes 4,637,948 shares issuable upon the vesting of RSUs granted under our 2004 Equity Incentive Plan.  The 

remaining balance consists of outstanding stock option grants under various plans. 

(3)  The weighted average exercise price does not take into account the shares issuable upon vesting of outstanding RSUs, 

which have no exercise price. 

(4)  Includes outstanding options to purchase an aggregate of 97,210 shares of our common stock assumed through our 

acquisitions of TelCom Semiconductor, Inc. in January 2001, and PowerSmart, Inc. in June 2002.  At March 31, 2010, 
these assumed options had a weighted average exercise price of $21.00 per share.  No additional options may be granted 
under these plans. 

Equity Compensation Plans Not Approved by Stockholders 

Microchip Technology Incorporated 1997 Nonstatutory Stock Option Plan 

In November 1997, our Board of Directors approved the Microchip 1997 Nonstatutory Stock Option Plan, or our 1997 

Plan.  Under our 1997 Plan, nonqualified stock options were granted to employees who were not officers or directors of 
Microchip and to our consultants.  The 1997 Plan was not submitted to our stockholders for approval because doing so was not 
required under applicable rules and regulations in effect at the time the plan was initially adopted or when it was amended.  As 
of March 31, 2010, options to acquire 4,085,693 shares were outstanding under the 1997 Plan and no shares were available for 
future grant because this plan was replaced with our 2004 Equity Incentive Plan for future grants. 

The expiration date, maximum number of shares purchasable, and other provisions of options granted under the 1997 

Plan, including vesting provisions, were established at the time of grant by either the Compensation Committee or the Employee 
Committee appointed by the Board of Directors, provided that the exercise price of an option could not be less than the fair 
market value of our common stock on the date of grant and no option could have a term of more than 10 years.  If Microchip is 
acquired by merger, consolidation or asset sale, each outstanding option that is not assumed by the successor corporation or 

32 

 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
otherwise replaced with a comparable option will automatically accelerate and vest in full.  In connection with a change of 
control of Microchip by tender offer or proxy contest for board membership, our Board of Directors can accelerate the vesting 
of outstanding options.  Our Board of Directors or Compensation Committee may amend or terminate the 1997 Plan without 
stockholder approval, but no amendment or termination of the 1997 Plan may adversely affect any award previously granted 
under the 1997 Plan without the written consent of the stock option holder. 

CODE OF ETHICS 

On May 3, 2004, our Board of Directors adopted a code of ethics for our directors, officers (including our chief 

executive officer and chief financial officer), and employees.  A copy of the code of ethics is available on our website at the 
Corporate/Investors section under Mission Statement/Corporate Governance on www.microchip.com. 

We intend to post on our website any amendment to, or waiver from, a provision of our codes of ethics within four 

business days following the date of such amendment or waiver or such other time period required by SEC rules.  

Other Matters to be Presented at the Annual Meeting 

OTHER MATTERS 

At the date this proxy statement went to press, we did not anticipate that any other matters would be raised at the 

annual meeting. 

Requirements, Including Deadlines, for Receipt of Stockholder Proposals for the 2011 Annual Meeting of Stockholders; 
Discretionary Authority to Vote on Stockholder Proposals 

Under SEC rules, if a stockholder wants us to include a proposal in our proxy statement and form of proxy for the 2011 

annual meeting, our Secretary must receive the proposal at our principal executive offices by March 14, 2011. Stockholders 
interested in submitting such a proposal are advised to contact knowledgeable counsel with regard to the detailed requirements 
of applicable securities laws.  The submission of a stockholder proposal does not guarantee that it will be included in our proxy 
statement. 

Under our Bylaws, stockholders must follow certain procedures to nominate a person for election as a director or to 

introduce an item of business at our annual meeting.  Under these procedures, stockholders must submit the proposed nominee 
or item of business by delivering a notice addressed to our Secretary at our principal executive offices.  We must receive notice 
as follows: 

  Normally we must receive notice of a stockholder's intention to introduce a nomination or proposed item of 

business for an annual meeting not less than 90 days before the first anniversary of the date on which we first 
mailed our proxy statement to stockholders in connection with the previous year's annual meeting of 
stockholders.  Accordingly, a stockholder who intends to submit a nomination or proposal for our 2011 annual 
meeting must do so no later than April 13, 2011.  

  However, if we hold our 2011 annual meeting on a date that is not within 30 days before or after the 

anniversary date of our 2010 annual meeting, we must receive the notice no later than the close of business on 
the later of the 90th day prior to our 2011 annual meeting or the 10th day following the day on which public 
announcement of the date of such annual meeting is first made.   

  A stockholder's submission must include certain specified information concerning the proposal or nominee, as 
the case may be, and information as to the stockholder's ownership of our common stock.  Proposals or 
nominations not meeting these requirements will not be considered at our 2011 annual meeting.   

 

If a stockholder does not comply with the requirements of this advance notice provision, the proxies may 
exercise discretionary voting authority under proxies it solicits to vote in accordance with its best judgment on 
any such proposal or nomination submitted by a stockholder.  

To make any submission or to obtain additional information as to the proper form and content of submissions, 

stockholders should contact our Secretary in writing at 2355 West Chandler Boulevard, Chandler, Arizona 85224-6199.  

33 

 
 
 
 
 
 
 
 
 
 
 
 
 
Householding of Annual Meeting Materials 

Some brokers and other nominee record holders may be participating in the practice of "householding" proxy 
statements and annual reports.  This means that only one copy of our proxy statement and annual report may have been sent to 
multiple stockholders in a stockholder's household.  Additionally, you may have notified us that multiple stockholders share an 
address and thus you requested to receive only one copy of our proxy statement and annual report.  While our proxy statement 
and 2010 Annual Report are available online (see "Electronic Access to Proxy Statement and Annual Report" on page 2), we 
will promptly deliver a separate copy of either document to any stockholder who contacts our investor relations department at 
480-792-7761 or by mail addressed to Investor Relations, Microchip Technology Incorporated, 2355 West Chandler Boulevard, 
Chandler, Arizona 85224-6199, requesting such copies.  If a stockholder is receiving multiple copies of our proxy statement and 
annual report at the stockholder's household and would like to receive a single copy of the proxy statement and annual report for 
a stockholder's household in the future, stockholders should contact their broker, or other nominee record holder to request 
mailing of a single copy of the proxy statement and annual report.  Stockholders receiving multiple copies of these documents 
directly from us, and who would like to receive single copies in the future, should contact our investor relations department to 
make such a request. 

Date of Proxy Statement 

The date of this proxy statement is July 12, 2010.

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 
reduce the system level energy consumption 
decrease time to market for their products  
significantly reduce product cost 

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 
accessories 

  3 

 
 
 
cordless and cellular telephones 


 motor controls 

security systems 

educational and entertainment devices 

consumer electronics 

power supplies 
touch screens 

 medical 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 at approximately $10.7 billion in calendar year 2009.  Microcontrollers are currently available in 4-bit 
through 32-bit architectures.  4-bit microcontrollers are the smallest segment of the microcontroller market and have been in 
decline for several years.  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.  

Our Products 

Our strategic focus is on embedded control solutions, including: 

 microcontrollers 


 memory products 

development tools 
analog and interface products 

We provide highly cost-effective embedded control solutions that also offer the advantages of small size, high 
performance, extreme low power, low voltage operation and ease of development, enabling timely and cost-effective 
embedded control product integration by our customers. 

Microcontrollers 

We offer a broad family of microcontroller products featuring our 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 8 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, extreme low 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 over 650 microcontrollers in our product portfolio, we target the 8-bit, 16-bit, and 
32-bit microcontroller markets.   

Digital Signal Controllers (DSC) are a subset of our 16-bit microcontroller offering.  Our dsPIC DSC 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-reprogrammability, large selection of peripheral functions, small footprint and ease of use, we believe 
that our dsPIC DSCs expand 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 DSC for specific applications and, we believe, are a 
key factor for obtaining design wins. 

Our family of development tools for PIC and dsPIC devices 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 PIC and dsPIC development tools 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 approximately 200 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 900,000 development tools. 

Analog and Interface Products 

Our analog and interface products consist of several families with approximately 600 power management, linear, mixed-
signal, thermal management, safety and security, and interface products.  At the end of fiscal 2010, our mixed-signal analog 
and interface products were being shipped to more than 14,000 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 also started selling Serial SRAM products over the last year. 
These are SRAM products with a serial interface compared to the traditional parallel interface that is more common, thus 
enabling a smaller footprint necessary in some embedded applications. 

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 our assembly and test operations, and by employing statistical techniques (statistical process control, designed 
experiments and wafer level monitoring), 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)  
 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 
2008 and the first half of fiscal 2009, Fab 2 operated at or above normal capacity levels, which we typically consider to be 
the range of 90% to 95% of the actual capacity of the installed equipment.  In response to lower demand in the second half of 

  5 

fiscal 2009, we reduced the production levels of Fab 2 below normal capacity levels.  Operating at lower percentages of 
capacity has a negative impact on our operating results due to the relatively high fixed costs inherent in wafer fabrication 
manufacturing.  We increased production levels of Fab 2 in the second and third quarters of fiscal 2010 to support increasing 
demand for our products.  During the latter part of the third quarter and the entire fourth quarter of fiscal 2010, we operated at 
or above normal capacity levels at Fab 2. 

Fab 4 currently produces 8-inch wafers using predominantly 0.22 to 0.5 micron manufacturing processes and is capable 

of supporting technologies below 0.18 microns.  Similar to Fab 2, Fab 4 was operating at or above normal capacity levels 
during the first half of fiscal 2009.  We reduced the production levels of Fab 4 in the second half of fiscal 2009 below normal 
capacity levels.  We increased production levels of Fab 4 in the second and third quarters of fiscal 2010 to support increasing 
demand for our products.  During the latter part of the third quarter and the entire fourth quarter of fiscal 2010, we operated at 
or above normal capacity levels at Fab 4.  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 and Fab 4 will provide sufficient capacity to allow us to respond to increases in future demand over the 
next several years with modest incremental capital expenditures. 

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 portion 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.  As of March 31, 2010, 
approximately 65% of our assembly requirements were being performed in our Thailand facility.  As of March 31, 2010, 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. 

During the first half of fiscal 2010, we operated at levels below the total operating capacity of our Thailand facility due 

to adverse business conditions.  During the second half of fiscal 2010, as business conditions improved, we operated at 
normal levels of capacity at our Thailand facility, and we selectively increased our assembly and test capacity at such facility. 

General Matters Impacting Our Manufacturing Operations 

We employ proprietary design and manufacturing processes in developing our microcontroller, analog 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, 
analog and memory product lines, we use a common process technology for our microcontroller, analog, 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 our 
effective use of our manufacturing facilities and equipment.  Maintenance of manufacturing productivity and yields are 
important factors in the achievement of our operating results.  The manufacture 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 manufacturing 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. 

Historically, we have relied on our ability to respond quickly to customer orders as part of our competitive strategy, 
resulting in customers placing orders with relatively short delivery schedules.  In order to respond to such requirements, we 
have historically maintained a significant work-in-process and finished goods inventory. 

At the end of fiscal 2010, we owned identifiable long-lived assets (consisting of property, plant and equipment) in the 
United States with a carrying value, net of accumulated depreciation, of $333.0 million and $160.0 million in other countries,  

  6 

including $147.7 million in Thailand.  At the end of fiscal 2009, we owned identifiable long-lived assets in the United States 
with a carrying value, net of accumulated depreciation, of $368.1 million and $163.6 million in other countries, including 
$152.4 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, 
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 enable new products and innovative 
features as well as achieve further cost reductions and performance improvements in existing products.   

In fiscal 2010, our R&D expenses were $120.8 million, compared to $115.5 million in fiscal 2009 and $120.9 million in 

fiscal 2008.  R&D expenses included share-based compensation expense of $12.2 million in fiscal 2010, $10.9 million in 
fiscal 2009 and $10.7 million in fiscal 2008. 

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 all three 
geographic markets.  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 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 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.   

In fiscal 2010, we derived 61% of our net sales through distributors and 39% of our net sales from customers serviced 
directly by Microchip.  In each of fiscal 2009 and fiscal 2008, we derived 64% of our net sales through distributors and 36% 
of our net sales from customers serviced directly by Microchip.  Our largest distributor accounted for approximately 12% of 
our net sales in fiscal 2010, 14% of our net sales in fiscal 2009 and 12% of our net sales in fiscal 2008.  No other distributor 
or end customer accounted for more than 10% of our net sales in fiscal 2010, fiscal 2009 or fiscal 2008.   

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 foreign customers accounted for approximately 77% of our net sales in fiscal 2010 and approximately 75% of 

our net sales in each of fiscal 2009 and fiscal 2008.  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 25% of our net sales in fiscal 2010, 
23% of our net sales in fiscal 2009 and approximately 20% of our net sales in fiscal 2008.  Sales to customers in Taiwan 
accounted for approximately 10% of our net sales in each of fiscal 2010 and fiscal 2008.  We did not have sales into any 
other foreign countries that exceeded 10% of our net sales during fiscal 2010, fiscal 2009 or fiscal 2008. 

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 to date as a result of export restrictions. 

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.  In recent periods, global economic conditions 
have 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, 2010, our backlog was approximately $527.6 million, compared to $182.8 million as of April 30, 2009.  

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 relatively 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.  We also compete with a number of companies that 
we believe have copied, cloned, pirated or reverse engineered our proprietary product lines in such countries as China, Korea 
and Taiwan.  We are continuing to take actions to vigorously and aggressively defend and protect our intellectual property on 
a worldwide basis. 

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 

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







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

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 U.S. and foreign patents, expiring on various dates between 2010 and 2028.  We also have 
numerous additional U.S. 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 technology and 

  8 

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 and new patents, trademarks and copyrights that issue may not be of sufficient scope or strength to provide 
meaningful intellectual property protection or any commercial advantage to us.  In addition, pursuing violations of our 
intellectual property rights on a worldwide basis is a complex business area involving patent law, trademark law, copyright 
law and the laws of certain foreign countries do not protect our intellectual property rights to the same extent as the laws of 
the U.S.   

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 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 material 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 recently adopted 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 March 31, 2010, we had 5,418 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 operating results were adversely impacted by global economic conditions and may fluctuate in the future due to a 
number of factors that could reduce our net sales and profitability. 

Our 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 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; 
risk of excess and obsolete inventories;  
changes in utilization of our manufacturing capacity and fluctuations in manufacturing yields; 
our ability to secure sufficient wafer foundry, assembly and testing capacity; 
availability of raw materials and equipment; 
competitive developments including pricing pressures; 
unauthorized copying of our products resulting in pricing pressure and loss of sales; 
the level of orders that are received and can be shipped in a quarter; 
the level of sell-through of our products through distribution; 
fluctuations in the mix of products; 
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 current or future tax audits or any litigation involving intellectual property, 
customers or other issues; 
changes in tax regulations and policies in the U.S. and other countries in which we do business; 
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; 
fluctuations in commodity prices; 
property damage or other losses, whether or not covered by insurance; and 
general economic, industry or political conditions in the U.S. 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 

  10 

 
effect on the price of our common stock.  Adverse global economic conditions and the subsequent economic recovery have 
caused our operating results to fluctuate significantly and make comparability between periods less meaningful. 

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.  In the quarter ended March 31, 2009, we 
reduced wafer starts in both Fab 2 and Fab 4, implemented rotating unpaid time off and had multiple planned shutdowns in 
our Thailand facility to help control inventory levels in response to adverse economic conditions.  This lower capacity 
utilization resulted in certain costs being charged directly to expense and lower gross margins.  In the quarter ended 
December 31, 2009, we increased our production output in our factories and did not have any shutdowns in our Thailand 
operation and reduced the amount of rotating unpaid time off in Fab 2 and Fab 4.  In the March 2010 quarter, we returned to 
a more optimal level of capacity utilization. 

We are dependent on orders that are received and shipped in the same quarter and are 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 relied on 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 reduce 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.  We may be 
unable to compete successfully in the future, which could harm our business.  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; 
our ability to remain price competitive against companies that have copied our proprietary product lines, 
especially in countries where intellectual property rights protection is difficult to achieve and maintain; 
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, primarily due to competitive conditions.  We have been able to moderate average selling price 

  11 

declines in many of our proprietary product lines by continuing to introduce new products with more features and higher 
prices.  However, there can be no assurance that we will be able to do so in the future.  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 and 
non-proprietary analog 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 approximately 61% of our net sales in fiscal 2010 and approximately 64% of our 

net sales in each of fiscal 2009 and fiscal 2008.  Our largest distributor accounted for approximately 14% of our net sales in 
fiscal 2009 and approximately 12% of our net sales in fiscal 2010.  We do not have long-term agreements with our distributors 
and we and our distributors may each terminate our relationship with little or no advance notice. 

Adverse conditions in the U.S. and global economies and in the U.S. and global credit markets could materially impact 

the operations of our distributors.  Any deterioration in the financial condition of our distributors or any disruption in the 
operations of our distributors could adversely impact the flow of our products to our end customers and adversely impact our 
results of operation.  In addition, during an industry and/or economic downturn, it is possible there will be an oversupply of 
products and a decrease in sell-through of our products by our distributors which could reduce our net sales in a given period 
and result in an increase in inventory returns.   

Recent credit conditions have adversely impacted our holdings of auction rate securities.  

At March 31, 2010, $37.2 million of the fair value of our investment portfolio was invested in auction rate securities 
(ARS).  Historically, the carrying value of ARS approximated fair value due to the frequent resetting of the interest rates.  
With the continuing liquidity issues in the global credit and capital markets, our ARS have experienced multiple failed 
auctions.  As a result, we will not be able to access such funds until a future auction on these investments is successful.   

$23.1 million of the fair value of our total ARS position is invested in student loan backed ARS.  We believe these 
investments are of high credit quality, as all of the investments carry AAA credit ratings by one or more of the major credit 
rating agencies and are largely backed by the federal government (Federal Family Education Loan Program).  Also, in 
November 2008, we executed an ARS rights agreement (the Rights) with the broker through which we purchased these ARS 
that provides (1) us with the right to put these ARS back to the broker at par anytime during the period from June 30, 2010 
through July 2, 2012, and (2) the broker with the right to purchase or sell the ARS at par on our behalf anytime through July 
2, 2012.  We intend to dispose of these ARS through the exercise of the put option on June 30, 2010.  

$14.1 million of the fair value of our total ARS position is invested in ARS whose underlying characteristics relate to 

servicing statutory requirements in the life insurance industry along with a small position related to a specialty finance 
company.  These ARS have experienced multiple rating downgrades by the major rating agencies.  The fair value of these 
ARS has been estimated based on market information and estimates determined by management and could change 
significantly based on market conditions.  Based on the estimated values, we concluded these investments were other than 
temporarily impaired and recognized an impairment charge on these investments of $3.6 million during fiscal 2009 and $4.7 
million during fiscal 2010.  If the issuers are unable to successfully close future auctions or if their credit ratings deteriorate 
further, we may be required to further adjust the carrying value of the investments through an additional impairment charge 
to earnings. 

The majority of our short and long-term investments are in highly rated government agency bonds, municipal, and 
corporate bonds.  Other than with respect to our holdings of ARS, we have not experienced any liquidity or impairment 
issues with such investments.  However, the credit markets have continued to be highly volatile and there can be no assurance 
that these conditions will not in the future adversely affect the liquidity or value of our investments in government agency 
bonds, municipal bonds, or corporate bonds. 

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; 
timely filing of intellectual property rights for new product designs; 
availability of development and 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. 

  12 

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 can be intense. 

Our success depends upon the efforts and abilities of our senior management, engineering and other personnel.  The 
competition for qualified engineering and management personnel can be 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 of required products and services 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 
replacement 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, fluctuations in our overall business in 
recent periods, semiconductor industry conditions and global economic conditions have had a more significant impact on our 
results than seasonality, and have 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 cyclically by selling proprietary products that cannot be 
easily or quickly replaced to a geographically diverse base of 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.   

  13 

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.  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, settle 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 products or using certain processes, suffer a reduction or 
elimination in the value of our 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 claims related to the manufacture, performance or use of 

our products.  These claims may be due to injury during manufacture, products' nonconformance to our specifications, or 
specifications agreed upon with the customer, changes in our manufacturing processes, and unexpected end customer system 
issues due to the interaction with our products or insufficient design or testing by our customers.  We could incur significant 
expenses related to such matters, including, but not limited to: 

 
 
 

 
 
 
 

costs related to writing off the value of inventory of nonconforming products;  
recalling nonconforming products;  
providing support services, product replacements, or modifications to products and the defense of such 
claims;  
diversion of resources from other projects;  
lost revenue or a delay in the recognition of revenue due to cancellation of orders and unpaid receivables;  
customer imposed fines or penalties for failure to meet contractual requirements; and  
a requirement to pay damages. 

Because the systems into which our products are integrated have a higher cost of goods than the products we sell, our 
expenses and damages may be significantly higher than the sales and profits we 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 liability insurance which covers damages arising out of product defects, but we do 
not expect 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 these customer 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 the systems in 
which our products are integrated could cause damage to property or persons.  We may be subject to claims if our products, 
or interactions with our products, cause the system failures.  We will face increased exposure to claims if there are substantial 
increases in either the volume of our sales into these applications or the frequency of system failures integrating our products. 

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 technology 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 
and new patents, trademarks and copyrights that issue 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, Patent Offices of a foreign country or U.S. or foreign courts, 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 U.S.  Infringement of our intellectual property rights by a third party could result 
in uncompensated lost market and revenue opportunities for us.  Although we continue to vigorously and aggressively defend 
and protect our intellectual property on a worldwide basis, there can be no assurance that we will be successful in our 
endeavors. 

Our operating results may be adversely impacted if economic conditions impact the financial viability of our customers, 
distributors, or suppliers. 

We regularly review the financial performance of our customers, distributors and suppliers.  However, global economic 
conditions may adversely impact the financial viability of our customers, distributors or suppliers.  The financial failure of a 
large customer or distributor, an important supplier, or a group thereof, could have an adverse impact on our operating results 
and could result in us not being able to collect our accounts receivable balances, higher reserves for doubtful accounts, write-
offs for accounts receivable, and higher operating costs as a percentage of revenues. 

  14 

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 had over 60,000 customers and our ten largest direct customers made up approximately 9% of our 
total revenue for the year ended March 31, 2010, cancellation of 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 specific 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 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 facilities, or at the facilities of any of our wafer fabrication or assembly and test 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 2010, approximately 77% of 
our net sales were made to foreign customers.  During fiscal 2009, approximately 75% 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, which has experienced periods of political 
instability in the past, and is currently experiencing some instability in Bangkok, though the current situation has not 
noticeably affected the area in which our facilities are located.  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 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; 
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/or our operating results could suffer. 

Fluctuations in foreign currency could impact our operating results.  We use forward currency exchange contracts to 
reduce the adverse earnings impact from the effect of exchange rate fluctuations on our non-U.S. dollar net balance sheet 
exposures.  Nevertheless, in periods when the U.S. dollar significantly fluctuates in relation to the non-U.S. currencies in 
which we transact business, the value of our non-U.S. dollar transactions can have an adverse effect on our results of 
operations and financial condition.  In particular, in periods when a foreign currency significantly declines in value in relation  

  15 

to the U.S. dollar, such as the recent decline in the Euro relative to the U.S. dollar, customers transacting in that foreign 
currency may find it more difficult to fulfill their previously committed contractual obligations or to undertake new 
obligations to make payments or purchase products. 

Interruptions in our information technology systems could adversely 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 new system implementations, 
computer viruses, security breaches, or 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 
still occur and 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 adversely 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 potentially significant risks and obligations.  In these circumstances, we have determined that it is more 
cost effective to self-insure certain risks than to pay the high premium costs.  The risks and exposures that we self-insure 
include, but are not limited to, certain property, 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 substances used in our products and manufacturing 
processes.  Our failure to comply with applicable regulations could result in the imposition of fines, suspension of 
production, cessation of operations or future liabilities.  Such environmental regulations have required us in the past and 
could require us in the future 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 also 
restrict our ability to ship certain products to certain countries, require us to modify our operations logistics, or require us to 
incur other significant costs and expenses.  Over the past several years, there has been an expansion in environmental laws 
focusing on reducing or eliminating hazardous substances in electronic products.  The European Union and countries such as 
the U.S., China, Korea and Brazil, have enacted or may enact such laws or regulations.  These and other future environmental 
regulations could require us to reengineer certain of our existing products and may make it more expensive for us to 
manufacture and sell our products.  In addition, over the last several years, the number and complexity of laws focused on the 
energy efficiency of electronic products and accessories, the recycling of electronic products, and the reduction in quantity 
and the recycling of packaging materials have expanded significantly.  It may be difficult for us to timely comply with these 
laws and we may not have sufficient quantities of compliant products to meet customers' needs, thereby adversely impacting 
our sales and profitability.  We may also have to write off inventory in the event that we hold inventory that is not saleable as 
a result of changes to regulations.  We expect these risks and trends to continue.  In addition, we anticipate increased 
customer requirements to meet voluntary criteria related to the reduction or elimination of hazardous substances in our 
products and energy efficiency measures. 

Climate change regulations and sustained adverse climate change poses both regulatory and physical risks that could 
harm our results of operations or affect the way we conduct our business. 

New climate change regulations could require us to limit emissions, change our manufacturing processes, obtain 
substitute materials that may cost more or be less available, fund offset projects or undertake other costly activities.  These 
regulations could significantly increase our costs and restrict our manufacturing operations by virtue of requirements for new 
equipment.  It is possible that new permits will be required for our current or expanded operations.  Failure to receive timely 
permits could result in the imposition of fines, suspension of production, or cessation of operations.  In addition, new 
restrictions on carbon dioxide or other greenhouse gas emissions could result in significant costs such as higher energy costs, 
and utility companies passing down carbon taxes, emission cap and trade programs and renewable portfolio standards.  
Greenhouse gas legislation has been introduced in the U.S. and we expect worldwide regulatory activity in the future.  The 
cost of complying, or of failing to comply, with these and other climate change and emissions regulations could have an 
adverse effect on our operating results. 

Further, any sustained adverse change in climate could have a direct adverse economic impact on us such as water 
shortages or higher costs for water or to control the temperature inside of our facilities.  Also, certain of our operations are 
located in tropical regions, such as Thailand.  Some environmental experts predict that these regions may become vulnerable  

  16 

to storms, floods and droughts due to climate change.  While we maintain business recovery plans that are intended to allow 
us to recover from natural disasters or other events that can be disruptive to our business, we cannot be certain that our plans 
will protect us from all such disasters or events.   

Regulatory authorities in jurisdictions into which we ship our products could levy fines or restrict our ability to export 
products. 

A significant portion of our sales are made outside of the U.S. through the exporting and re-exporting of products.  In 

addition to local jurisdictions' export regulations, our U.S.-manufactured products or products based on U.S. technology are 
subject to U.S. laws and regulations governing international trade and exports, including, but not limited to the Export 
Administration Regulations (EAR), and trade sanctions against embargoed countries and destinations administered by the 
U.S. Department of the Treasury, Office of Foreign Assets Control (OFAC).  Licenses or proper license exceptions are 
required for the shipment of our products to certain countries.  A determination by the U.S. or local government that we have 
failed to comply with these or other export regulations can result in penalties including denial of export privileges, fines, civil 
or criminal penalties, and seizure of products.  Such penalties could have a material adverse effect on our business including 
our ability to meet our net sales and earnings targets.  Further, a change in these laws and regulations could restrict our ability 
to export to previously permitted countries, customers, distributors or other third parties.  Any one or more of these sanctions 
or a change in law or regulations could have a material adverse effect on our business, financial condition and results of 
operations. 

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 examination of our income tax returns by the IRS and other tax authorities for fiscal 2006 and later.  

We are currently being audited by the IRS for fiscal 2006 through fiscal 2008.  We are subject to certain income tax 
examinations in foreign jurisdictions for fiscal 2002 and later.  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 our future operating results. 

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; 
any acquisitions we pursue or complete; 
general conditions in the semiconductor industry; and 
global economic and financial conditions. 

In addition, the stock market has from time to time experienced significant price and volume fluctuations that have 
affected the market prices for many companies and that often have been unrelated to the operating performance of such 
companies.  These broad market fluctuations and other factors have harmed and may harm the market price of our common 
stock. 

We may not fully realize the anticipated benefits of our completed or future acquisitions. 

We have acquired and expect in the future to acquire additional businesses that we believe will complement or augment 

our existing businesses.  The integration process for our acquisitions, including our recent acquisition of SST, may be 
complex, costly and time consuming and include unanticipated issues, expenses and liabilities.  We may not be able to 
successfully or profitably integrate, operate, maintain and manage any newly acquired operations or employees.  We may not 
be able to maintain uniform standards, procedures and policies and we may be unable to realize the expected synergies and 
cost savings from the integration.  There may be increased risk due to integrating financial reporting and internal control 
systems.  We may have difficulty in developing, manufacturing and marketing the products of a newly acquired company, or 
in growing the business at the rate we anticipate.  Following an acquisition, we may not achieve the revenue or net income 
levels that justify the acquisition.  We may suffer loss of key employees, customers and strategic partners of acquired 
companies.  We may be subject to claims by terminated employees, shareholders of acquired companies and other third 
parties related to the transaction.  Acquisitions may also result in one-time charges (such as acquisition-related expenses,  

  17 

write-offs, restructuring charges, or future impairment of goodwill), contingent liabilities, adverse tax consequences, 
additional stock-based compensation expense and other charges that adversely affect our operating results.  Additionally, we 
may fund acquisitions of new businesses or strategic alliances by utilizing cash, raising debt, issuing shares of common stock, 
or other mechanisms. 

While the risks above are relevant to all of our acquisitions, our recent acquisition of SST is a larger and more complex 
transaction than our other recent transactions and may expose us to greater risks and liabilities than we have encountered in 
the past. 

Further, when we decide to sell assets or a business, such as certain assets of SST, we may encounter difficulty in finding 

or completing divestiture opportunities or alternative exit strategies on acceptable terms or in a timely manner.  These 
circumstances could delay the accomplishment of our strategic objectives or cause us to incur additional expenses with 
respect to a business that we want to dispose of, or we may dispose of a business at a price or on terms that are less favorable 
than we had anticipated. 

In addition to acquisitions, we have in the past and expect in the future to enter into joint development agreements or 
other business or strategic relationships with other companies.  These transactions are subject to a number of risks similar to 
those we face with our acquisitions including our ability to realize the expected benefits of any such transaction, to 
successfully market and sell any products resulting from such transactions or to successfully integrate any technology 
developed through such transactions. 

Our financial condition and results of operations could be adversely affected if we do not effectively manage our 
liabilities. 

As a result of our sale of $1.15 billion of principal value 2.125% junior subordinated convertible debentures in December 

2007, we have a substantially greater amount of long-term debt than we have maintained in the past.  Our maintenance of 
substantial levels of debt could adversely affect our ability to take advantage of corporate opportunities and could adversely 
affect our financial condition and results of operations.  We may need or desire to refinance all or a portion of our debentures or 
any other future indebtedness that we incur on or before the maturity of the debentures.  There can be no assurance that we will be 
able to refinance any of our indebtedness on commercially reasonable terms, if at all. 

We may in the future incur impairments to goodwill or long-lived assets.  

We review our long-lived assets, including goodwill and other intangible assets, for impairment annually in the fourth 

quarter or whenever events or changes in circumstances indicate that the carrying amount of those assets may not be 
recoverable.  Factors that may be considered in assessing whether goodwill or intangible assets may not be recoverable 
include a decline in our stock price or market capitalization, reduced estimates of future cash flows and slower growth rates 
in our industry.  Our valuation methodology for assessing impairment requires management to make judgments and 
assumptions based on historical experience and to rely heavily on projections of future operating performance.  Because we 
operate in highly competitive environments, projections of future operating results and cash flows may vary significantly 
from results.  No goodwill or long-lived assets impairment charges were recorded in fiscal 2010.  

Conversion of our debentures will dilute the ownership interest of existing stockholders, including holders who had 
previously converted their debentures. 

The conversion of some or all of our outstanding debentures will dilute the ownership interest of existing stockholders to 

the extent we deliver common stock upon conversion of the debentures.  Upon conversion, we may satisfy our conversion 
obligation by delivering cash, shares of common stock or any combination, at our option.  If upon conversion we elect to deliver 
cash for the lesser of the conversion value and principal amount of the debentures, we would pay the holder the cash value of the 
applicable number of shares of our common stock.  Upon conversion, we intend to satisfy the lesser of the principal amount or the 
conversion value of the debentures in cash.  If the conversion value of a debenture exceeds the principal amount of the debenture, 
we may also elect to deliver cash in lieu of common stock for the conversion value in excess of the one thousand dollars principal 
amount (i.e. the conversion spread).  There would be no adjustment to the numerator in the net income per common share 
computation for the cash settled portion of the debentures as that portion of the debt instrument will always be settled in cash.  The 
conversion spread will be included in the denominator for the computation of diluted net income per common share.  Any sales in 
the public market of any common stock issuable upon such conversion could adversely affect prevailing market prices of our 
common stock.  In addition, the existence of the debentures may encourage short selling by market participants because the 
conversion of the debentures could be used to satisfy short positions, or anticipated conversion of the debentures into shares of our 
common stock could depress the price of our common stock.

Our reported financial results may be adversely affected by new accounting pronouncements or changes in existing 
accounting standards and practices.  

We prepare our financial statements in conformity with accounting principles generally accepted in the U.S.  These 
accounting principles are subject to interpretation or changes by the FASB and the SEC.  New accounting pronouncements 
and varying interpretations of accounting standards and practices have occurred in the past and may occur in the future.  New 
accounting pronouncements or a change in the interpretation of existing accounting standards or practices may have a 
significant effect on our reported financial results and may even affect our reporting of transactions completed before the 
change is announced or effective. 

Recently proposed U.S. tax legislation regarding our foreign earnings could materially and adversely impact our business 
and financial results. 

Currently, a majority of our revenue is generated from customers located outside the U.S., and a substantial portion of 

our assets, including employees, are located outside the U.S.  Present U.S. income taxes and foreign withholding taxes have 
not been provided on undistributed earnings for certain of our non-U.S. subsidiaries, because such earnings are intended to be 
indefinitely reinvested in the operations of those subsidiaries.  In fiscal 2009, President Obama's administration announced 
initiatives that would substantially reduce our ability to defer U.S. taxes including repealing the deferral of U.S. taxation of 
foreign earnings, eliminating utilization of or substantially reducing our ability to claim foreign tax credits, and eliminating 
various tax deductions until foreign earnings are repatriated to the U.S.  If any of these proposals become law, they could 
have a material negative impact on our financial position and results of operations.

In addition to the facilities we own, we lease several research and development facilities and sales offices in North

We currently believe that our existing facilities are suitable and will be adequate to meet our requirements for at least the 

next 12 months. 

See page 33 for a discussion of the capacity utilization of our manufacturing facilities. 

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.  We also periodically receive notification from 
various third parties alleging infringement of patents, intellectual property rights or other matters.  With respect to these 
pending legal actions to which we are a party, 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  

  19 

 
 
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 March 16, 2010, plaintiffs – stockholders of SST purporting to act on behalf of all public stockholders of SST – filed 

a Consolidated Amended Class Action Complaint (the "Amended Complaint") in Santa Clara California Superior Court (In 
re Silicon Storage Technology, Inc. Shareholder Litigation, No. 1-09-CV-157437) which generally alleges that the directors 
of SST breached fiduciary duties owed to SST stockholders when approving the merger transaction with Microchip.  The 
Amended Complaint alleges that by approving the merger with Microchip, the directors prevented the SST stockholders from 
receiving full value for their shares.  The Amended Complaint also names Microchip as a defendant, claiming that Microchip 
aided and abetted in the purported breaches of fiduciary duties by the SST director defendants.  The Amended Complaint 
seeks alternative relief either to enjoin the transaction with Microchip or to rescind the deal or obtain compensatory damages, 
in the event the merger was consummated while the litigation was pending.  Given that the merger closed on April 8, 2010, 
plaintiffs' request to enjoin the transaction has been rendered moot.  Microchip believes the Amended Complaint lacks merit 
and intends to defend against the claims vigorously.

certain factors including those set forth in "Item 1A – Risk Factors," and elsewhere in this Form 10-K.  Although we believe 
that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of 
activity, performance or achievements.  You should not place undue reliance on these forward-looking statements.  We 
disclaim any obligation to update information contained in any forward-looking statement. 

As further discussed in Note 1 to our consolidated financial statements, our consolidated financial statements for each 
year presented here have been adjusted for the retrospective application of the Cash Conversion subsections of Accounting 
Standards Codification Subtopic 470-20, "Debt with Conversion and Other Options – Cash Conversion." 

Introduction 

The following discussion should be read in conjunction with the 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 30, we discuss our Results of Operations for fiscal 2010 compared to fiscal 2009, and 
for fiscal 2009 compared to fiscal 2008.  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, interface devices, Serial EEPROMs, 
® security devices.  We provide highly cost-effective embedded control products that also offer the 
and our patented KEELOQ
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. 

We sell our products to a broad base of domestic and international customers across a variety of industries.  

The principal markets that we serve include consumer, automotive, industrial control, computing and communications.  Our 
business is subject to fluctuations based on economic conditions within these markets.  Beginning with the third quarter of 
fiscal 2009, the downturn in the U.S. and global economies adversely impacted our key markets resulting in adverse 
fluctuations in our business.  However, in fiscal 2010 we saw an upturn in our key markets, resulting in improvements to our 
business across all product lines. 

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 our assembly and test operations, and by employing statistical process control techniques, we have been able to  

  25 

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, 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 our products. 

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 for our customers 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 our 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 U.S.  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, share-based compensation, inventories, investments, income taxes, property, plant and equipment, impairment of 
property, plant and equipment, junior subordinated convertible debentures 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.  Our 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 generally have broad price protection and product return rights, so we defer revenue 
recognition until the distributor sells the product to their customer.  Revenue is recognized when the distributor sells the 
product to an end-user, at which time the sales price becomes fixed or determinable.  Revenue is not recognized upon 
shipment to our distributors since, due to discounts from list price as well as price protection rights, the sales price is not 
substantially fixed or determinable at that time.  At the time of shipment to these distributors, we record a trade receivable for  

  26 

the selling price as there is a legally enforceable right to payment, relieve inventory for the carrying value of goods shipped 
since legal title has passed to the distributor, and record the gross margin in deferred income on shipments to distributors on 
our consolidated balance sheets.  

Deferred income on shipments to distributors effectively represents the gross margin on the sale to the distributor; 
however, the amount of gross margin that we recognize in future periods could be less than the deferred margin as a result of 
credits granted to distributors on specifically identified products and customers to allow the distributors to earn a competitive 
gross margin on the sale of our products to their end customers and price protection concessions related to market pricing 
conditions. 

We sell the majority of the items in our product catalog to our distributors worldwide at a uniform list price.  However, 
distributors resell our products to end customers at a very broad range of individually negotiated price points.  The majority 
of our distributors' resales require a reduction from the original list price paid.  Often, under these circumstances, we remit 
back to the distributor a portion of their original purchase price after the resale transaction is completed in the form of a credit 
against the distributors' outstanding accounts receivable balance.  The credits are on a per unit basis and are not given to the 
distributor until they provide information to us regarding the sale to their end customer.  The price reductions vary 
significantly based on the customer, product, quantity ordered, geographic location and other factors and discounts to a price 
less than our cost have historically been rare.  The effect of granting these credits establishes the net selling price 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.  Thus, a portion of the "deferred income on shipments to distributors" balance represents the amount of 
distributors' original purchase price that will be credited back to the distributor in the future.  The wide range and variability 
of negotiated price concessions granted to distributors does not allow us to accurately estimate the portion of the balance in 
the deferred income on shipments to distributors account that will be credited back to the distributors.  Therefore, we do not 
reduce deferred income on shipments to distributors or accounts receivable by anticipated future concessions; rather, price 
concessions are typically recorded against deferred income on shipments to distributors and accounts receivable when 
incurred, which is generally at the time the distributor sells the product.  At March 31, 2010, we had approximately $148.4 
million of deferred revenue and $49.5 million in deferred cost of sales recognized as $98.9 million of deferred income on 
shipments to distributors.  At March 31, 2009, we had approximately $118.2 million of deferred revenue and $34.3 million in 
deferred cost of sales recognized as $83.9 million of deferred income on shipments to distributors.  The deferred income on 
shipments to distributors that will ultimately be recognized in our income statement will be lower than the amount reflected 
on the balance sheet due to additional price credits to be granted to the distributors when the product is sold to their 
customers.  These additional price credits historically have resulted in the deferred income approximating the overall gross 
margins that we recognize in the distribution channel of our business. 

Distributor advances, reflected as a reduction of deferred income on shipments to distributors on our consolidated 
balance sheets, totaled $57.5 million at March 31, 2010 and $37.6 million at March 31, 2009.  On sales to distributors, our 
payment terms generally require the distributor to settle amounts owed to us for an amount in excess of their ultimate cost.  
The sales price to our distributors may be higher than the amount that the distributors will ultimately owe us because 
distributors often negotiate price reductions after purchasing the product from us and such reductions are often significant.  It 
is our practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable 
balances, on a current basis, generally within 30 days, for amounts originally invoiced.  This practice has an adverse impact 
on the working capital of our distributors.  As such, we have entered into agreements with certain distributors whereby we 
advance cash to the distributors to reduce the distributor's working capital requirements.  These advances are reconciled at 
least on a quarterly basis and are estimated based on the amount of ending inventory as reported by the distributor multiplied 
by a negotiated percentage.  Such advances have no impact on our revenue recognition or our consolidated statements of 
income.  We process discounts taken by distributors against our deferred income on shipments to distributors' balance and 
true-up the advanced amounts generally after the end of each completed fiscal quarter.  The terms of these advances are set 
forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand.  The 
agreements governing these advances can be cancelled by us at any time. 

We reduce product pricing through price protection based on market conditions, competitive considerations and other 

factors.  Price protection is granted to distributors on the inventory 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 
immediate revenue impact from the price protection, as it is reflected as a reduction of the deferred income on shipments to 
distributors' balance. 

  27 

Products returned by distributors and subsequently scrapped have historically been immaterial to our consolidated results 

of operations.  We routinely evaluate the risk of impairment of the deferred cost of sales component of the deferred income 
on shipments to distributors account.  Because of the historically immaterial amounts of inventory that have been scrapped, 
and historically rare instances where discounts given to a distributor result in a price less than our cost, we believe the 
deferred costs are recorded at their approximate carrying value. 

Share-based Compensation 

We measure at fair value and recognize compensation expense for all share-based payment awards, including grants of 
employee stock options, restricted stock units (RSUs) and employee stock purchase rights, to be recognized in our financial 
statements based on their respective grant date fair values.  Total share-based compensation in fiscal 2010 was $36.8 million, 
of which $29.7 million was reflected in operating expenses.  Total share-based compensation included in cost of sales in 
fiscal 2010 was $7.1 million.  Total share-based compensation included in our inventory balance was $3.2 million at March 
31, 2010. 

Determining the appropriate fair-value model and calculating the fair value of share-based awards at the date of grant 
requires judgment.  The fair value of our RSUs is based on the fair market value of our common stock on the date of grant 
discounted for expected future dividends.  We use the Black-Scholes option pricing model to estimate the fair value of 
employee stock options and rights to purchase shares under stock participation plans.  Option pricing models, including the 
Black-Scholes model, also require the use of input assumptions, including expected volatility, expected life, expected 
dividend rate, and expected risk-free rate of return.  We use a blend of historical and implied volatility based on options 
freely traded in the open market as we believe this is more reflective of market conditions and a better indicator of expected 
volatility than using purely historical volatility.  The expected life of the awards is based on historical and other economic 
data trended into the future.  The risk-free interest rate assumption is based on observed interest rates appropriate for the 
terms of our awards.  The dividend yield assumption is based on our history and expectation of future dividend payouts.  We 
estimate the number of share-based awards that will be forfeited due to employee turnover.  Quarterly changes in the 
estimated forfeiture rate can have a significant effect on reported share-based compensation, as the effect of adjusting the rate 
for all expense amortization after April 1, 2006 is recognized in the period the forfeiture estimate is changed.  If the actual 
forfeiture rate is higher or lower than the estimated forfeiture rate, then an adjustment is made to increase or decrease the 
estimated forfeiture rate, which will result in a decrease or increase to the expense recognized in our financial statements.  If 
forfeiture adjustments are made, they would affect our gross margin, research and development expenses, and selling, 
general, and administrative expenses.  The effect of forfeiture adjustments in fiscal 2010 was immaterial. 

We evaluate the assumptions used to value our awards on a quarterly basis.  If factors change and we employ different 
assumptions, share-based compensation expense may differ significantly from what we have recorded in the past.  If there are 
any modifications or cancellations of the underlying unvested securities, we may be required to accelerate, increase or cancel 
any remaining unearned share-based compensation expense.  Future share-based compensation expense and unearned share-
based compensation will increase to the extent that we grant additional equity awards to employees or we assume unvested 
equity awards in connection with acquisitions.  

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.  During subsequent periods, if sales occur of previously written-
down inventory, we may realize a higher gross margin on sales of this inventory during the period the inventory is sold.  In 
estimating our inventory obsolescence, we primarily evaluate estimates of demand over a 12-month period and record 
impairment charges for inventory on hand in excess of the estimated 12-month demand.   

In periods where our production levels are substantially below our normal operating capacity, such as in the second half 

of fiscal 2009 and the first half of fiscal 2010, the reduced production levels of our manufacturing facilities are charged 
directly to cost of sales.  Approximately $18.6 million was charged to cost of sales in fiscal 2009, and approximately 
$22.3 million was charged to cost of sales in fiscal 2010, as a result of decreased production in our wafer fabs. 

Investments 

We classify our investments as trading securities or available-for-sale securities based upon management's intent with 

regard to the investments and the nature of the underlying securities.   

  28 

Our trading securities consist of auction rate securities (ARS) that we intend to dispose of through the exercise of a put 
option. (See Note 4 to our consolidated financial statements for further discussion of the ARS put option.)  Our investments 
in trading securities are carried at fair value with unrealized gains and losses reported in other income (expense).   

Our available-for-sale investments consist of government agency bonds, municipal bonds, ARS, strategic investments in 
shares of publicly traded common stock and corporate bonds.  Our investments are carried at fair value with unrealized gains 
and losses reported in stockholders' equity to the extent any unrelated losses are determined to be temporary.  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.  

We include within our short-term investments our trading securities, as well as our income yielding available-for-sale 
securities that can be readily converted to cash and include within long-term investments those income yielding available-for-
sale securities with maturities of over one year that have unrealized losses attributable to them or those that cannot be readily 
liquidated.  We have the ability to hold our long-term investments with temporary impairments until such time as these assets 
are no longer impaired.  Such recovery of unrealized losses is not expected to occur within the next year.   

Due to the lack of availability of observable market quotes on certain of our investment portfolio of ARS, we utilize 
valuation models including those that are based on expected cash flow streams and collateral values, including assessments of 
counterparty credit quality, default risk underlying the security, discount rates and overall capital market liquidity.  The 
valuation of our ARS investment portfolio is subject to uncertainties that are difficult to predict.  Factors that may impact our 
ARS valuation include changes to credit ratings of the securities as well as to the underlying assets supporting those 
securities, rates of default of the underlying assets, underlying collateral value, discount rates, counterparty risk, the ongoing 
strength and quality of the credit markets, and market liquidity.  

The credit markets experienced significant deterioration and uncertainty beginning in the second half of fiscal 2008.  If 

these conditions continue, or we experience any additional ratings downgrades on any investments in our portfolio (including 
our ARS), we may incur additional impairments to our investment portfolio, which could negatively affect our financial 
condition, cash flows and results of operation.  

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 in our consolidated balance sheets.  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, 2010, our gross deferred tax asset was $78.9 million. 

Various taxing authorities in the U.S. and other countries in which we do business scrutinize the 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 U.S. Internal Revenue Service (IRS) for our 
fiscal years ended 2006, 2007 and 2008.  Fiscal years 2009 and 2010 are open for examination by tax authorities.  We 
recognize liabilities for anticipated tax audit issues in the U.S. 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 these and other pending audits in the U.S. 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 and 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, 2010, the carrying value of our property and equipment totaled 
$493.0 million, which represented 19.6% 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 5 to 7 years on manufacturing equipment, from 10 to 15 years on leasehold improvements and 
approximately 30 years on buildings.  

  29 

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, 2010, 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. 

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. 

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. 

Junior Subordinated Convertible Debentures 

We separately account for the liability and equity components of our junior subordinated convertible debentures in a 
manner that reflects our nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized.  This results in 
a bifurcation of a component of the debt, classification of that component in equity and the accretion of the resulting discount 
on the debt to be recognized as part of interest expense in our consolidated statements of operations.  Additionally, certain 
embedded features of the debentures qualify as derivatives and are bundled as a compound embedded derivative that is 
measured at fair value.  Lastly, we  include the dilutive effect of the shares of our common stock issuable upon conversion of 
the outstanding junior subordinated convertible debentures in our diluted income per share calculation regardless of whether 
the market price trigger or other contingent conversion feature has been met.  We apply the treasury stock method as we have 
the intent and current ability to settle the principal amount of the junior subordinated convertible debentures in cash.  This 
method results in incremental dilutive shares when the average fair value of our common stock for a reporting period exceeds 
the conversion price per share which was $30.34 at March 31, 2010 and adjusts as dividends are recorded in the future. 

Litigation 

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

can reasonably estimate the amount and range of loss.  Recorded reserves were immaterial at March 31, 2010. 

Because of the uncertainties related to both the probability of loss and the amount and range of loss on our 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 affect our results of operations and financial 
position.

Net Sales 

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.  
In certain circumstances, a customer's financial condition may require collateral, and, in such cases, the collateral would be 
provided primarily by letters of credit. 

Our net sales of $947.7 million in fiscal 2010 increased by $44.4 million, or 4.9%, over fiscal 2009, and our net sales of 

$903.3 million in fiscal 2009 decreased by $132.4 million, or 12.8%, over fiscal 2008.  The increase in net sales in fiscal 
2010 over fiscal 2009 was due primarily to improving semiconductor industry conditions and market share gains in our 
strategic product lines.  The decrease in net sales in fiscal 2009 over fiscal 2008 resulted primarily from adverse changes in 
global economic and end market conditions across all of our product lines.  Average selling prices for our products were 
down approximately 7% in fiscal 2010 over fiscal 2009 and were down approximately 4% in fiscal 2009 over fiscal 2008.  
The number of units of our products sold was up approximately 12% in fiscal 2010 over fiscal 2009 and down approximately 
9% in fiscal 2009 over fiscal 2008.  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.  Key factors impacting the amount of net sales during the last 
three fiscal years include:

our new product offerings that have increased our served available market; and 
continued market share gains.

Microcontrollers 

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

application development systems accounted for approximately 81% of our total net sales in each of fiscal 2010 and fiscal 
2009, and approximately 80.4% of our total net sales in fiscal 2008.   

Net sales of our microcontroller products increased approximately 4.9% in fiscal 2010 compared to fiscal 2009, and 
decreased approximately 12.2% in fiscal 2009 compared to fiscal 2008.  The increase in net sales in fiscal 2010 compared to 
fiscal 2009 resulted primarily from improving semiconductor industry conditions, market share gains and the other factors 
described above.  The decrease in net sales in fiscal 2009 compared to fiscal 2008 was primarily due to adverse global 
economic conditions in the markets we serve and the other factors described above.  The end markets we serve include 
consumer, automotive, industrial control, communications and computing 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 8.5% of our total net sales in fiscal 2010, approximately 

9.9% of our total net sales in fiscal 2009 and approximately 11.6% of our total net sales in fiscal 2008.

Net sales of our memory products decreased approximately 10.3% in fiscal 2010 compared to fiscal 2009, and decreased 

approximately 25.7% in fiscal 2009 compared to fiscal 2008.  These sales decreases were driven primarily by global 
economic conditions and 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 10.5% of our total net sales in fiscal 2010, 

approximately 9.1% of our total net sales in fiscal 2009 and approximately 8.0% of our total net sales in fiscal 2008. 

Net sales of our analog and interface products increased approximately 21.3% in fiscal 2010 compared to fiscal 2009 and 

were essentially flat in fiscal 2009 compared to fiscal 2008.  The increase in net sales in fiscal 2010 compared to fiscal 2009 
was driven primarily by improving semiconductor industry conditions and market share gains achieved within the analog and 
interface market.  Net sales of our analog and interface products in fiscal 2009 compared to fiscal 2008 were driven primarily 
by deteriorating global economic conditions, market share gains and supply and demand conditions within the analog and 
interface market. 

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 61% of our net sales in fiscal 2010, and 64% of our net sales in each of fiscal 2009 and fiscal 

2008. 

Our largest distributor accounted for approximately 12% of our net sales in fiscal 2010, approximately 14% of our net 
sales in fiscal 2009 and approximately 12% of our net sales in fiscal 2008.  Our two largest distributors together accounted 
for approximately 17% of our net sales in fiscal 2010, and approximately 19% of our net sales in each of fiscal 2009 and 
fiscal 2008. 

Generally, we do not have long-term agreements with our distributors and we, or our distributors, may terminate our 
relationship with each other 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, 2010, our distributors maintained 41 days of inventory of our products compared to 38 days at March 31, 
2009 and 33 days at March 31, 2008.  Over the past three fiscal years, the days of inventory maintained by our distributors 
have fluctuated between approximately 31 days and 42 days.  Thus, inventory levels at our distributors are at the higher end 
of the range we have experienced over the last three fiscal 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.

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 U.S., Canada, Central America and South America.   

Sales to foreign customers accounted for approximately 77% of our net sales in fiscal 2010 and approximately 75% of 

our net sales in each of fiscal 2009 and fiscal 2008.  Substantially all of our foreign sales are U.S. dollar denominated.  Sales 
to customers in Asia have generally increased over time due to many of our customers transitioning their manufacturing 
operations to Asia and growth in demand from the emerging Asian market.  Our sales force in the Americas and Europe 
supports a significant portion of the design activity for products which are ultimately shipped to Asia. 

Sales to customers in China, including Hong Kong, accounted for approximately 25% of our net sales in fiscal 2010, 
approximately 23% of our net sales in fiscal 2009 and approximately 20% of our net sales in fiscal 2008.  Sales to customers 
in Taiwan accounted for approximately 10% of our net sales in each of fiscal 2010 and fiscal 2008.  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 $534.2 million in fiscal 2010, $516.5 million in fiscal 2009 and $624.9 million in fiscal 2008.  

Gross profit as a percent of sales was 56.4% in fiscal 2010, 57.2% in fiscal 2009 and 60.3% in fiscal 2008. 

The most significant factors affecting our gross profit percentage in the periods covered by this report were: 





production levels being below the range of our normal capacity, such as in the second half of fiscal 2009 
and the first half of fiscal 2010, resulting in under absorption of fixed costs; and 
continual cost reductions in wafer fabrication and assembly and test manufacturing, such as new 
manufacturing technologies and more efficient manufacturing techniques. 

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





inventory write-downs partially offset by sales of inventory that was previously written down; 
lower depreciation as a percentage of cost of sales; and  
fluctuations in the product mix of microcontrollers, proprietary and non-proprietary analog products and 
Serial EEPROM products resulting in lower overall average selling prices for our products. 

We adjust our capacity utilization as required to respond to actual and anticipated business and industry-related 
conditions.  We operated at or above normal capacity levels, which we typically consider to be 90% to 95% of the actual 
capacity of the installed equipment, during fiscal 2008, the first half of fiscal 2009 and the fourth quarter of fiscal 2010.  
However, during the third and fourth quarters of fiscal 2009, we reduced wafer starts at both Fab 2 and Fab 4 and 
implemented rotating unpaid time off at both fabrication facilities.  The reduction in wafer starts and rotating unpaid time off 
were implemented to help control inventory levels due to adverse economic conditions in the markets we serve.  Reduced 
levels of production continued into the third quarter of fiscal 2010, however, we increased the production output from our 
wafer fabs in the second and third quarters of fiscal 2010 to support increasing demand for our products and during the latter 
part of the third quarter of fiscal 2010 and during the fourth quarter of fiscal 2010, we operated our wafer fabs at or above 
normal capacity levels. 

As a result of decreased production in our wafer fabs, approximately $22.3 million was charged to cost of sales in 

fiscal 2010 and approximately $18.6 million was charged to cost of sales in fiscal 2009.  There were no such charges in fiscal 
2008.  In the future, if production levels are below normal capacity, we will charge cost of sales for the unabsorbed capacity. 

The process technologies utilized in our wafer fabs impact our gross margins.  Fab 2 currently utilizes various 

manufacturing process technologies, but predominantly utilizes our 0.5 to 1.0 micron processes.  Fab 4 predominantly utilizes 
our 0.22 to 0.5 micron processes.  We continue to transition products to more advanced process technologies to reduce future 
manufacturing costs.  All of our production has been on 8-inch wafers during the periods covered by this report. 

Our overall inventory levels were $116.6 million at March 31, 2010, compared to $131.5 million at March 31, 2009 and 
$124.5 million at March 31, 2008.  We maintained 97 days of inventory on our balance sheet at March 31, 2010 compared to 
134 days of inventory at March 31, 2009 and 112 days at March 31, 2008.  The reduction of our inventory levels from the 
March 31, 2009 levels was a result of our efforts to manage inventory through the period of adverse global economic 
conditions and was impacted by net sales in each quarter in fiscal 2010 exceeding our initial expectations when entering 
those periods.  Our inventory levels at March 31, 2010 were at the low end of the range we have experienced over the last 
three years.  Our goal is to grow our inventory balances to more optimized levels over time. 

  33 

We anticipate that our gross margins will fluctuate over time, driven primarily by capacity utilization levels, 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, and competitive and economic 
conditions in the markets we serve.  

At March 31, 2010, approximately 65% of our assembly requirements were performed in our Thailand facility, 
compared to approximately 77% at March 31, 2009 and approximately 67% at March 31, 2008.  The percentage of our 
assembly work that is performed internally fluctuates over time based on supply and demand conditions in the semiconductor 
industry and our internal capacity capabilities.  Third-party 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 portion of our wafer fabrication requirements. 

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

subcontract.  While we review the quality, delivery and cost performance of our third-party contractors, our future operating 
results could suffer if any third-party contractor is unable to maintain manufacturing yields, assembly and test yields and 
costs at approximately their current levels. 

Research and Development (R&D) 

R&D expenses for fiscal 2010 were $120.8 million, or 12.8% of sales, compared to $115.5 million, or 12.8% of sales, 
for fiscal 2009 and $120.9 million, or 11.7% of sales, for fiscal 2008.  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.  R&D costs are expensed as incurred.  
Assets purchased to support our ongoing research and development activities are capitalized when related to products which 
have achieved technological feasibility or that have alternative future uses and are amortized over their expected useful lives.  
R&D expenses include 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 $5.3 million, or 4.6%, for fiscal 2010 over fiscal 2009.  The primary reasons for the dollar 
increase in R&D costs in fiscal 2010 compared to fiscal 2009 were higher salary and bonus costs related to restoring previous 
reductions in compensation programs due to improving business conditions.  R&D expenses decreased $5.3 million, or 4.4%, 
for fiscal 2009 over fiscal 2008.  The primary reasons for the dollar decrease in R&D costs in fiscal 2009 compared to fiscal 
2008 were cost-cutting actions taken in the third and fourth quarters of fiscal 2009, including salary reductions, elimination of 
bonuses and reductions in travel costs.    

Selling, General and Administrative 

Selling, general and administrative expenses for fiscal 2010 were $167.2 million, or 17.7% of sales, compared to 

$161.2 million, or 17.9% of sales, for fiscal 2009, and $175.6 million, or 16.9% of sales, for fiscal 2008.  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. 

Selling, general and administrative expenses increased $6.0 million, or 3.7%, for fiscal 2010 over fiscal 2009.  The 
primary reasons for the dollar increase in selling, general and administrative expenses in fiscal 2010 over fiscal 2009 were 
higher salary and bonus costs related to restoring previous reductions in compensation programs due to improving business 
conditions.  Selling, general and administrative expenses decreased $14.4 million, or 8.2%, for fiscal 2009 over fiscal 2008.  
The primary reasons for the dollar decrease in selling, general and administrative expenses in fiscal 2009 over fiscal 2008 
were cost-cutting actions taken in the third and fourth quarters of fiscal 2009, including salary reductions, elimination of 
bonuses and reduction in travel costs.   

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

investment levels.

Special Charges 

Patent Licenses 

During the first quarter of fiscal 2010, we agreed to the terms of a patent license with an unrelated third party and signed 

an agreement on July 9, 2009.  The patent license settled alleged infringement claims.  The total payment made to the third-
party in July 2009 was $1.4 million, $1.2 million of which was expensed in the first quarter of fiscal 2010 and the remaining 
$0.2 million was recorded as a prepaid royalty that will be amortized over the remaining life of the patent. 

We entered into a patent portfolio license effective March 31, 2009 with an unrelated third-party that covers both issued 
patents and patent applications and settled alleged infringement claims.  The total payment made to the third-party was $8.25 
million, $4.0 million of which was expensed in the fourth quarter of fiscal 2009 and the remaining $4.25 million of which 
was recorded as a prepaid royalty that will be amortized over the life of the patents.  

Expenses Associated with the Abandonment of the Atmel Acquisition  

On October 2, 2008, we and ON Semiconductor Corporation announced that we had sent a proposal to the Board of 
Directors of Atmel Corporation to acquire Atmel for $5.00 per share in cash or a total of approximately $2.3 billion.  On 
October 29, 2008, Atmel announced that its Board of Directors had determined that the unsolicited proposal was inadequate.  
On February 10, 2009, we announced our termination of our consideration of a potential transaction with Atmel in light of 
the economic uncertainty and the lack of visibility with respect to Atmel's business not allowing us to put a value on Atmel.  
In the fourth quarter of fiscal 2009, we expensed $1.6 million of various costs associated with the terminated proposal. 

In-Process Research and Development  

During the third quarter of fiscal 2009, we completed our acquisition of Hampshire Company, a leader in the large 
format touch screen controller market.  As a result of the acquisition, we incurred a $0.5 million in-process research and 
development charge in the third quarter of fiscal 2009. 

During the fourth quarter of fiscal 2009, we completed the acquisition of HI-TECH Software, a provider of software 

development tools and compilers. As a result of the acquisition, we incurred a $0.2 million in-process research and 
development charge in the fourth quarter of fiscal 2009. 

During the fourth quarter of fiscal 2009, we completed our acquisition of R&E International, a leader in developing 
innovative integrated circuits for smoke and carbon monoxide detectors and other life-safety systems.  As a result of the 
acquisition, we incurred a $0.2 million in-process research and development charge in the fourth quarter of fiscal 2009. 

Loss on Sale of Fab 3 

We received an unsolicited offer on our Fab 3 facility in September 2007.  We assessed our available capacity in our 
current facilities, along with our capacity available from outside foundries and determined the capacity of Fab 3 would not be 
required in the near term.  As a result of this assessment, we accepted the offer on September 21, 2007 and the transaction 
closed on October 19, 2007.  We received $27.5 million in cash net of expenses associated with the sale and recognized an 
impairment charge in fiscal 2008 of $26.8 million on the sale of Fab 3, representing the difference between the carrying value 
of the assets at September 30, 2007 and the amounts realized subsequent to September 30, 2007.   

Other Income (Expense) 

Interest income in fiscal 2010 decreased to $15.3 million from $32.5 million in fiscal 2009.  Interest income in fiscal 
2009 decreased to $32.5 million from $54.9 million in fiscal 2008.  The primary reason for the reductions in interest income 
in fiscal 2010 over fiscal 2009 and for fiscal 2009 over fiscal 2008 was lower interest rates on our invested cash balances in 
those periods.  Interest expense related to our 2.125% junior subordinated convertible debentures in fiscal 2010 was 
$31.2 million, compared to $29.4 million in fiscal 2009 and $9.5 million in fiscal 2008.  Other income, net in fiscal 2010 was 
$8.7 million compared to other expense, net of $4.4 million in fiscal 2009 and other income, net in fiscal 2008 of 
$2.4 million.  The increase in other income, net in fiscal 2010 compared to fiscal 2009 and fiscal 2008 primarily relates to 
$7.5 million of gains on trading securities during fiscal 2010 compared to $7.3 million of losses on trading securities during 
fiscal 2009.  These gains and losses were a result of market fluctuations in our trading securities and the put options as 
described in Note 4 to our consolidated financial statements.   

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 8.8% in fiscal 2010, our effective tax benefit was 5.8% in fiscal 2009 and our effective tax rate was 
15.1% in fiscal 2008.  Our effective tax rate is lower than statutory rates in the U.S. due primarily to lower tax rates at our 
foreign locations, R&D tax credits and export sales incentives.  Our effective tax rate in fiscal 2010 reflects a $8.5 million 
U.S. tax benefit related to our settlement with the IRS for our fiscal 2002 through fiscal 2004 tax audits.  This benefit reduced 

  35 

our effective tax rate by 3.6 percentage points to an effective tax rate of 8.8%.  Our effective tax rate in fiscal 2009 reflects a 
$16.9 million U.S. tax benefit related to our settlement with the IRS for our fiscal 2005 tax audit and a $33.0 million tax 
reserve release associated with a favorable clarification of tax regulations which had an ongoing benefit on our effective tax 
rate.  Combined, these tax benefits reduced our effective tax rate by 21.5 percentage points to an effective tax benefit of 
5.8%.  Our effective tax rate in fiscal 2008 reflects a $10.3 million U.S. tax benefit associated with the sale of Fab 3, a 
$5.7 million tax benefit related to the release of tax reserves associated with a foreign tax matter, a $4.5 million tax benefit 
related to the release of tax reserves for certain international tax exposures and approximately $0.8 million related to accrued 
interest and other reserve matters.  Combined, these tax benefits decreased our effective tax rate in fiscal 2008 by 
approximately 4.4% to an effective tax rate of 15.1%. 

Various taxing authorities in the U.S. and other countries in which we do business are increasing their scrutiny of the 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 2006, 2007 and 2008.  We are currently open for examination by the tax authorities for our fiscal years ended 2009 and 
2010.  We recognize liabilities for anticipated tax audit issues in the U.S. 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 these and other pending audits in the U.S. 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 in the future and any expiration of our tax holidays in Thailand are expected to have a 
minimal impact on our overall tax expense due to other tax holidays and increases in income in other taxing jurisdictions with 
lower statutory rates. 

Liquidity and Capital Resources 

We had $1,531.5 million in cash, cash equivalents and short-term and long-term investments at March 31, 2010, an 
increase of $90.8 million from the March 31, 2009 balance.  The increase in cash, cash equivalents and short-term and long-
term investments over this time period is primarily attributable to cash generated by operating activities being offset by 
dividends during the fiscal year ended March 31, 2010. 

Net cash provided from operating activities was $452.0 million for fiscal 2010, $308.7 million for fiscal 2009 and 
$447.3 million for fiscal 2008.  The increase in cash flow from operations in fiscal 2010 compared to fiscal 2009 was 
primarily due to net sales of trading securities in fiscal 2010 of $87.0 million, compared to net purchases of trading securities 
of $73.5 million in fiscal 2009.  The lower net income in fiscal 2010, was also offset by changes in working capital.  The 
decrease in cash flow from operations in fiscal 2009 compared to fiscal 2008 was primarily due to lower net income in fiscal 
2009, an increase in the purchases of trading securities and changes in accrued liabilities and other assets and liabilities.  

Net cash used in investing activities was $195.3 million for fiscal 2010, and $19.8 million for fiscal 2009.  Net cash 
provided by investing activities was $55.7 million in fiscal 2008.  The increase in net cash used in investing activities in 
fiscal 2010 compared to fiscal 2009 was primarily due to changes in our net purchases, sales and maturities of short-term and 
long-term investments offset by lower capital expenditures in fiscal 2010.  Also included in net cash used in investing 
activities in fiscal 2010 was a $58.4 million investment in the common stock of Silicon Storage Technology, Inc. at $3.05 per 
share.  The decrease in cash provided by investing activities in fiscal 2009 over fiscal 2008 was primarily due to an increase 
in capital expenditures and investments in other assets, as well as $27.5 million received from the sale of Fab 3 in fiscal 2008.   

Net cash used in financing activities was $195.3 million for fiscal 2010, $330.2 million for fiscal 2009 and 

$182.7 million for fiscal 2008.  Proceeds from the exercise of stock options and employee purchases under our employee 
stock purchase plans were $36.5 million for fiscal 2010, $33.6 million for fiscal 2009 and $59.1 million for fiscal 2008.  We 
paid cash dividends to our shareholders of $249.6 million in fiscal 2010, $246.7 million in fiscal 2009, and $252.0 million in 
fiscal 2008.  Excess tax benefits from share-based payment arrangements were $2.1 million in fiscal 2010, $6.8 million in 
fiscal 2009, and $21.2 million in fiscal 2008.  During the year ended March 31, 2008, we received net proceeds of 
$1,127.0 million from the issuance of our 2.125% junior subordinated convertible debentures.  Cash expended for the 
repurchase of our common stock was $123.9 million in fiscal 2009 and $1,138.0 million in fiscal 2008.  No amounts were 
expended in fiscal 2010 for the repurchase of our common stock.   

Our level of capital expenditures varies from time to time as a result of actual and anticipated business conditions.  
Capital expenditures were $47.6 million in fiscal 2010, $102.4 million in fiscal 2009 and $69.8 million in fiscal 2008.  
Capital expenditures are primarily for the expansion of production capacity and the addition of research and development 

  36 

equipment.  We currently intend to spend approximately $90 million during the next twelve months to invest in equipment 
and facilities to maintain, and increase capacity, as required, to meet our currently anticipated needs.   

We expect to finance our 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 twelve months will provide sufficient 
manufacturing capacity to meet our currently anticipated needs.   

We enter into derivative transactions from time to time in an attempt to reduce 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.  At March 31, 2010, we had no foreign 
currency-forward contracts outstanding. 

On December 11, 2007, we announced that our Board of Directors had authorized the repurchase of up to an additional 

10,000,000 shares of our common stock in the open market or in privately negotiated transactions.  As of March 31, 2010, 
2,460,002 shares related to this authorization remained available for purchase. 

Our Board of Directors authorized the repurchase of 21,500,000 shares of our common stock concurrent with our junior 
subordinated convertible debentures transaction described in Note 11 to our consolidated financial statements and no further 
shares are available to be repurchased under this authorization. 

As of March 31, 2010, approximately 33.5 million shares of our common stock remained as treasury shares with the 
balance of the repurchased shares being used to fund share issuance requirements under our equity incentive plans.  The 
timing and amount of future repurchases will depend upon market conditions, interest rates, 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.  During fiscal 2008, we paid dividends in the amount of $1.205 per share for a total dividend payment 
of $252.0 million.  During fiscal 2009, we paid dividends in the amount of $1.346 per share for a total dividend payment of 
$246.7 million.  During fiscal 2010, we paid dividends in the amount of $1.359 per share for a total dividend payment of 
$249.6 million.  On May 5, 2010, we declared a quarterly cash dividend of $0.342 per share, which will be paid on June 2, 
2010, to stockholders of record on May 20, 2010 and the total amount of such dividend is expected to be approximately 
$63.5 million.  Our Board of Directors is free to change our dividend practices at any time and to increase or decrease 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 of Directors.  Our current intent is to 
provide for ongoing quarterly cash dividends depending upon market conditions and our results of operations. 

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 twelve 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 acquisitions or 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, competitive factors and our ability to identify suitable 
acquisition candidates.  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, 2010, 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, 2010 (dollars in thousands):  

Operating lease obligations 
Capital purchase obligations (1) 
Other purchase obligations and

(1)  Capital purchase obligations represent commitments for construction or purchases of property, plant and equipment.  
These obligations were not recorded as liabilities on our balance sheet as of March 31, 2010, 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)  For purposes of this table we have assumed that the principal of our convertible debentures will be paid on 

December 31, 2037. 

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

liabilities, or certain purchase obligations as discussed below.  The contractual obligations also do not include 
amounts related to uncertain tax positions because reasonable estimates cannot be made. 

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 us 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, 2010, we are not involved in any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of 

SEC Regulation S-K. 

Recently Issued Accounting Pronouncements 

In July 2009, the Financial Accounting Standards Board (FASB) released the final version of its new "Accounting 
Standards Codification" (Codification) as the single authoritative source for GAAP.  While not intended to change GAAP, 
the Codification significantly changed the way in which the accounting literature is organized, combining all authoritative 
standards into a comprehensive, topically organized database.  All existing accounting standard documents were superseded 
and all other accounting literature not included in the Codification is considered nonauthoritative, other than guidance issued 
by the SEC.  The Codification was effective for interim and annual periods ending on or after September 15, 2009.  We 
adopted the Codification in our interim financial statements for the second quarter of fiscal 2010, which had no impact on our 
financial position, results of operations or cash flows.  

In April 2009, the FASB issued guidance for estimating fair value when the volume or level of activity in a market for an 

asset or liability has decreased significantly.  This guidance also provides information on identifying circumstances that 
indicate a transaction is not orderly (i.e., a forced liquidation or distressed sale).  This guidance was effective for us beginning 
in fiscal 2010 and did not have a material impact on our financial position, results of operations or cash flows.  

In April 2009, the FASB issued guidance that applies to investments in debt securities for which other-than-temporary 
impairments may be recorded. If an entity's management asserts that it does not have the intent to sell a debt security and it is 
more likely than not that it will not be required to sell the security before recovery of its cost basis, then an entity may 
separate other-than-temporary impairments into two components: (i) the amount related to credit losses (recorded in 
earnings) and (ii) all other amounts (recorded in other comprehensive income).  This guidance was effective for us beginning 
in fiscal 2010 and did not have a material impact on our financial position, results of operations or cash flows.  

In April 2009, the FASB issued guidance that requires disclosures about fair value of financial instruments in interim 
financial statements.  This guidance was effective for us beginning in fiscal 2010, and because it applies only to financial 
statement disclosures, it had no impact on our financial position, results of operations or cash flows.  

In June 2008, the FASB issued guidance clarifying that unvested share-based payment awards with a right to receive 
nonforfeitable dividends are participating securities and providing information on how to allocate earnings to participating 
securities to allow computation of basic and diluted earnings per share using the two-class method.  This guidance was 
effective for us beginning in fiscal 2010 and requires retrospective application for periods prior to the effective date.  The 
adoption of this guidance did not have a material impact on our computation of earnings per share.  

  38 

 
In April 2008, the FASB issued guidance that amends the factors that should be considered in developing renewal or 
extension assumptions used to determine the useful life of a recognized intangible asset.  This guidance was effective for us 
beginning in fiscal 2010 and did not have a material impact on our financial position, results of operations or cash flows.  

In December 2007, the FASB issued a revision to previously issued accounting literature which changes the accounting 

for business combinations including: (i) the measurement of acquirer shares issued in consideration for a business 
combination, (ii) the recognition of contingent consideration, (iii) the accounting for preacquisition gain and loss 
contingencies, (iv) the recognition of capitalized IPR&D, (v) the accounting for acquisition-related restructuring costs, 
(vi) the treatment of acquisition-related transaction costs, and (vii) the recognition of changes in the acquirer's income tax 
valuation allowance.  We began applying this guidance prospectively to all business combinations beginning in fiscal 2010. 
The impact of adoption on our financial position, results of operations or cash flows is dependent upon the nature and terms 
of business combinations that we consummate.  

New Accounting Pronouncements Not Yet Adopted  

In October 2009, the FASB issued new revenue recognition guidance for arrangements that include both software and 
non-software related deliverables.  This guidance requires entities to allocate the overall consideration to each deliverable by 
using a best estimate of the selling price of individual deliverables in the arrangement in the absence of VSOE or other third 
party evidence of the selling price.  Additionally, the guidance modifies the manner in which the transaction consideration is 
allocated across the separately identified deliverables by no longer permitting the residual method of allocating arrangement 
consideration.  The new guidance is effective for us in the first quarter of fiscal 2012 interim financial statements, with earlier 
adoption permitted.  We are currently evaluating the impact of adopting this new guidance on our consolidated financial 
statements.  

In June 2009, the FASB issued new guidance on accounting for transfers of financial assets, which amended previous 
GAAP literature.  The amendment includes: (i) elimination of the qualifying special-purpose entity concept, (ii) a new unit of 
account definition that must be met for transfers of portions of financial assets to be eligible for sale accounting, 
(iii) clarifications and changes to the derecognition criteria for a transfer to be accounted for as a sale, (iv) a change to the 
amount of recognized gain or loss on a transfer of financial assets accounted for as a sale when beneficial interests are 
received by the transferor, and (v) extensive new disclosures.  This guidance is effective for us beginning in fiscal 2011 and 
is not expected to have a material effect on our financial position, results of operations or cash flows.  

Item 7A.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK  

As of March 31, 2010 and March 31, 2009, our investment portfolio, consisting of fixed income securities and money 
market funds that we hold on an available-for-sale basis, totaled $1,506.6 million and $1,318.83 million respectively, and our 
trading securities totaled $24.9 million and $122.5 million, respectively.  Our available-for-sale 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):

At March 31, 2010, $49.8 million of original purchase value of our investment portfolio was invested in ARS.  

Historically, the carrying value of auction rate securities (ARS) approximated fair value due to the frequent resetting of the 
interest rates.  If an auction fails for amounts we have invested, our investment will not be liquid.  With the continuing 
liquidity issues experienced in the global credit and capital markets, our ARS have experienced multiple failed auctions.  In 
September 2007 and February 2008, auctions for $24.9 million and $34.8 million, respectively, of the original purchase value 
of our investments in ARS had failed.  While we continue to earn interest on these investments based on a pre-determined 
formula with spreads tied to particular interest rate indices, the estimated market value for a portion of these ARS no longer 
approximates the original purchase value. 

The $24.9 million in failed auctions noted above have continued to fail through the filing date of this Annual Report on 

Form 10-K.  The fair value at March 31, 2010 of the failed ARS of $14.2 million has been estimated based on market 
information and estimates determined by management and could change significantly based on future market conditions.  We 
evaluated the impairments in the value of these ARS, determining our intent to sell these securities prior to the recovery of its 
amortized cost basis resulted in the securities being other-than-temporarily impaired and recognized an impairment charge on  

  39 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
these investments of $3.6 million during fiscal 2009 and $4.7 million in fiscal 2010.  If the issuers are unable to successfully 
close future auctions or if their credit ratings deteriorate further, we may be required to further adjust the carrying value of the 
investments through an additional impairment charge to earnings. 

The $34.8 million of ARS that failed during February 2008 are investments in student loan-backed ARS (SLARS).  
Approximately $2.9 million and $7.0 million of these SLARS were redeemed at par by the issuers during the fiscal years 
2009 and 2010, respectively, reducing our overall position in these SLARS to $24.9 million which represents the initial cost 
basis for these investments.  Based upon our evaluation of available information, we believe these investments are of high 
credit quality, as all of the investments carry AAA credit ratings by one or more of the major credit rating agencies and are 
largely backed by the federal government (Federal Family Education Loan Program).   

The fair value of the failed SLARS has been estimated based on market information and estimates determined by 
management and could change significantly based on future market conditions.  However, if the issuers are not able to 
successfully close future auctions or over time are not able to obtain more favorable financing options for their debt issuance 
needs, including refinancing these obligations into lower rate securities, the market value of these investments could be 
negatively impacted.   

In November 2008, we executed an SLARS rights agreement (the Rights) with the broker through which we purchased 
the $24.9 million in ARS that provides (1) us with the right to put these SLARS back to the broker at par anytime during the 
period from June 30, 2010 through July 2, 2012, and (2) the broker with the right to purchase or sell the ARS at par on our 
behalf anytime through July 2, 2012.  We accounted for the acceptance of the Rights as the receipt of a put option for no 
consideration and recognized a gain with a corresponding recognition as a long-term investment.  We expect any future 
change in the fair value of the SLARS to be largely offset by changes in the fair value of the related Rights without any 
significant net impact to our income statement.  We will continue to measure the SLARS and the Rights at fair value 
(utilizing Level 3 inputs) until the earlier of maturity or exercise.  We intend and have the ability to hold the $24.9 million of 
ARS until the market recovers or until June 30, 2010 when we have the right to sell the SLARS at par to the broker as we do 
not anticipate having to sell these securities to fund the operations of our business.  We believe that, based on our current 
unrestricted cash, cash equivalents and short-term investment balances, the current lack of liquidity in the credit and capital 
markets will not have a material impact on our liquidity, cash flow or ability to fund our operations. 

Our investment in marketable equity securities at March 31, 2010 consisted of shares of common stock of Silicon 
Storage Technology, Inc., the value of which is determined by the closing price of such shares on the market on which the 
shares are traded as of the balance sheet date.  The market value of this investment was approximately $58.4 million at March 
31, 2010 and was equal to our purchase price of $3.05 per share.  On April 8, 2010, we acquired Silicon Storage Technology, 
Inc. in a merger transaction for $3.05 per share for a total of $295.4 million in consideration in addition to the shares we 
purchased for $58.4 million.  The $58.4 million of market value of these securities will be included in the determination of 
our total purchase price of $353.8 million.

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  

  40 

 
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 
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 our financial 
statements. 

Management assessed our internal control over financial reporting as of March 31, 2010, 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. 

Ernst & Young LLP, an independent registered public accounting firm, who audited our consolidated financial 

statements included in this Form 10-K has issued an attestation report on our internal control over financial reporting, which 
is included in Part II, Item 9A. 

Changes in Internal Control over Financial Reporting 

During the three months ended March 31, 2010, 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

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

We have audited Microchip Technology Incorporated’s internal control over financial reporting as of March 31, 

2010, 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 included in the accompanying Management’s Report 
on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal 
control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 

(U.S.). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether 
effective internal control over financial reporting was maintained in all material respects. Our audit included 
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, 
and performing such other procedures as we considered necessary in the circumstances. We believe that our audit 
provides a reasonable basis for our opinion. 

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

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

In our opinion, Microchip Technology Incorporated maintained, in all material respects, effective internal 

control over financial reporting as of March 31, 2010, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(U.S.), the March 31, 2010 consolidated financial statements of Microchip Technology Incorporated and our report 
dated June 1, 2010 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, 2010 and 2009, and the related consolidated statements of income, stockholders’ equity, 
and cash flows for each of the three years in the period ended March 31, 2010. 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 
(U.S.). 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, 2010 and 2009, 
and the consolidated results of their operations and their cash flows for each of the three years in the period ended 
March 31, 2010, in conformity with U.S. generally accepted accounting principles. 

As discussed in Note 1 and Note 10 to the consolidated financial statements, effective April 1, 2007, the 
Company changed its method of accounting for uncertain tax positions.  Additionally, as discussed in Note 1 to the 
consolidated financial statements, the Company retrospectively changed its method of accounting for its convertible 
debentures. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 

(U.S.), the effectiveness of Microchip Technology Incorporated’s internal control over financial reporting as of 
March 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission and our report dated June 1, 2010 expressed an 
unqualified opinion thereon.

MICROCHIP TECHNOLOGY INCORPORATED AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1. 

SIGNIFICANT ACCOUNTING POLICIES 

Nature of Business 

Microchip develops, manufactures and sells specialized semiconductor products used by its customers for a 
wide variety of embedded control applications.  Microchip's product portfolio comprises 8-bit, 16-bit and 32-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, safety and security and interface devices.  Microchip also makes serial 
EEPROMs.  

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 or determinable pricing and collectability is reasonably assured.  The 
Company recognizes revenue from product sales to original equipment manufacturers (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.  Revenue is recognized when the distributor sells the product to their end customer, at which time the 
sales price becomes fixed or determinable.  Revenue is not recognized upon the Company's shipment to the 
distributors since, due to discounts from list price as well as price protection rights, the sales price is not 
substantially fixed or determinable at that time.  At the time of shipment to these distributors, the Company records 
a trade receivable for the selling price as there is a legally enforceable right to payment, relieves inventory for the 
carrying value of goods shipped since legal title has passed to the distributor, and records the gross margin in 
deferred income on shipments to distributors on the consolidated balance sheets.  

Deferred income on shipments to distributors effectively represents the gross margin on the sale to the 

distributor; however, the amount of gross margin recognized by the Company in future periods will be less than the 
deferred margin as a result of credits granted to distributors on specifically identified products and customers to 
allow the distributors to earn a competitive gross margin on the sale of the Company's products to their end 
customers and price protection concessions related to market pricing conditions. 

The Company sells the majority of the items in its product catalog to its distributors worldwide at a uniform list 

price.  However, distributors resell the Company's products to end customers at a very broad range of individually 
negotiated price points.  The majority of the Company's distributors' resales require a reduction from the original list 
price paid.  Often, under these circumstances, the Company remits back to the distributor a portion of their original 
purchase price after the resale transaction is completed in the form of a credit against the distributors' outstanding 
accounts receivable balance.  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 price reductions vary significantly based on the 
customer, product, quantity ordered, geographic location and other factors and discounts to a price less than the 
Company's cost have historically been rare.  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.  Thus, a portion of the "deferred income on shipments to 
distributors" balance represents the amount of distributors' original purchase price that will be credited back to the 
distributor in the future.  The wide range and variability of negotiated price concessions granted to distributors does 
not allow the Company to accurately estimate the portion of the balance in the deferred income on shipments to 
distributors account that will be credited back to the distributors.  Therefore, the Company does not reduce deferred 
income on shipments to distributors or accounts receivable by anticipated future price concessions; rather, price 
concessions are recorded against deferred income on shipments to distributors when incurred, which is generally at 
the time the distributor sells the product.   

F-6 

 
 
 
At March 31, 2010, the Company had approximately $148.4 million of deferred revenue and $49.5 million in 
deferred cost of sales recognized as $98.9 million of deferred income on shipments to distributors.  At March 31, 
2009, the Company had approximately $118.2 million of deferred revenue and $34.3 million of deferred cost of 
sales recognized as $83.9 million of deferred income on shipments to distributors.  The deferred income on 
shipments to distributors that will ultimately be recognized in the Company's income statement will be lower than 
the amount reflected on the balance sheet due to price credits to be granted to the distributors when the product is 
sold to their customers.  These price credits historically have resulted in the deferred income approximating the 
overall gross margins that the Company recognizes in the distribution channel of its business. 

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 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 immediate revenue impact from the price protection, as it is 
reflected as a reduction of the deferred income on shipments to distributors' balance. 

Products returned by distributors and subsequently scrapped have historically been immaterial to the Company's 

consolidated results of operations.  The Company routinely evaluates the risk of impairment of the deferred cost of 
sales component of the deferred income on shipments to distributors account.  Because of the historically immaterial 
amounts of inventory that have been scrapped, and historically rare instances where discounts given to a distributor 
result in a price less than the Company's cost, the Company believes the deferred costs have a low risk of material 
impairment. 

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 its 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 immaterial as of and for the fiscal years ended March 31, 2010, 2009 and 
2008. 

Advertising Costs 

The Company expenses all advertising costs as incurred.  Advertising costs were immaterial for the fiscal years 

ended March 31, 2010, 2009 and 2008. 

Research and Development 

Research and development costs are expensed as incurred.  Assets purchased to support the Company's ongoing 

research and development activities are capitalized when related to products which have achieved technological 
feasibility or that have alternative future uses and are amortized over their estimated useful lives.  Research and 
development expenses include expenditures for labor, share-based payments, depreciation, 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 (expense) in the consolidated statements 
of income.  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 have been 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  

F-7 

 
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.   

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation (FIN) No. 48, 
Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement 109 which was codified into 
ASC 740-10.  This guidance establishes a single model to address accounting for uncertain tax positions and 
clarifies the accounting for income taxes by prescribing a minimum recognition threshold a tax position is required 
to meet before being recognized in the financial statements.  ASC 740-10 also provides guidance on de-recognition, 
measurement classification, interest and penalties, accounting in interim periods, disclosure and transition.  The 
Company adopted this guidance on April 1, 2007, and did not recognize any cumulative-effect adjustment 
associated with its unrecognized tax benefits, interest, and penalties.   

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. 

Investments 

The Company classifies its investments as trading securities or available-for-sale securities based upon 

management's intent with regard to the investments and the nature of the underlying securities.   

The Company's trading securities consist of Auction Rate Securities (ARS) that the Company intends to dispose 

of through the exercise of a put option.  See further discussion in Note 4.  The Company's investments in trading 
securities are carried at fair value with unrealized gains and losses reported in other, net in the consolidated 
statements of income.   

The Company's available-for-sale investments consist of government agency bonds, municipal bonds, ARS, 
strategic investments in shares of publicly traded common stock and corporate bonds.  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.   

The Company includes within short-term investments its trading securities, as well as its income yielding 
available-for-sale securities that can be readily converted to cash and includes within long-term investments those 
income yielding available-for-sale securities with maturities of over one year that have unrealized losses attributable 
to them.  The Company has both the intent and 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.   

Due to the lack of availability of observable market quotes on certain of the Company's investment portfolio of 
ARS, it utilizes valuation models including those that are based on expected cash flow streams and collateral values, 
including assessments of counterparty credit quality, default risk underlying the security, discount rates and overall 
capital market liquidity.  The valuation of the Company's ARS investment portfolio is subject to uncertainties that 
are difficult to predict.   Factors that may impact the Company's ARS valuation include changes to credit ratings of 
the securities as well as to the underlying assets supporting those securities, rates of default of the underlying assets, 
underlying collateral value, discount rates, counterparty risk, the ongoing strength and quality of the credit market, 
and market liquidity.  

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.   

F-8 

 
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 twelve-month period and provides reserves for inventory on hand in excess of the estimated twelve-month 
demand. 

In periods where the Company's production levels are substantially below normal operating capacity, such as in 

the second half of fiscal 2009 and the first half of fiscal 2010, unabsorbed overhead production associated with the 
reduced production levels of the Company's manufacturing facilities are charged directly to cost of sales. 

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. 

Junior Subordinated Convertible Debentures  

The Company separately accounts for the liability and equity components of its junior subordinated convertible 

debentures in a manner that reflects its nonconvertible debt (unsecured debt) borrowing rate when interest cost is 
recognized.  This results in a bifurcation of a component of the debt, classification of that component in equity and 
the accretion of the resulting discount on the debt to be recognized as part of interest expense in its consolidated 
statements of income.  Additionally, certain embedded features of the debentures qualify as derivatives and are 
bundled as a compound embedded derivative that is measured at fair value.  Lastly, the Company includes the 
dilutive effect of the shares of its common stock issuable upon conversion of the outstanding junior subordinated 
convertible debentures in its diluted income per share calculation regardless of whether the market price trigger or 
other contingent conversion feature has been met.  The Company applies the treasury stock method as it has the 
intent and current ability to settle the principal amount of the junior subordinated convertible debentures in cash.  
This method results in incremental dilutive shares when the average market value of its common stock for a 
reporting period exceeds the conversion price per share which was $30.34 at March 31, 2010 and adjusts as 
dividends are recorded in the future. 

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 outcome and range of the any potential losses 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 its results of operation.  Through March 31, 2010, the Company has not had impaired 
goodwill.   

F-9 

 
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 has equity incentive plans under which non-qualified stock options and restricted stock units 
(RSUs) have been granted to employees and non-employee members of the Board of Directors.  In the second half 
of fiscal 2006, the Company adopted RSUs as its primary equity incentive compensation instrument for employees.  
The Company also has an employee stock purchase plan for all eligible employees. 

The Company estimates the fair value of share-based payment awards on the date of grant using an option 

pricing model.  The value of the portion of the award that is ultimately expected to vest is recognized as expense 
ratably over the requisite service periods.  The Company has estimated the fair value of each award as of the date of 
grant using the Black-Scholes option pricing model, which was developed for use in estimating the value of traded 
options that have no vesting restrictions and that are freely transferable.  The Black-Scholes model considers, among 
other factors, the expected life of the award and the expected volatility of the Company's stock price.   

Determining the appropriate fair-value model and calculating the fair value of share-based awards at the date of 
grant requires judgment.  The fair value of RSUs is based on the fair market value of the Company's common stock 
on the date of grant discounted for expected future dividends.  The Company uses the Black-Scholes option pricing 
model to estimate the fair value of employee stock options and rights to purchase shares under stock participation 
plans.  Option pricing models, including the Black-Scholes model, also require the use of input assumptions, 
including expected volatility, expected life, expected dividend rate, and expected risk-free rate of return.  The 
Company uses a blend of historical and implied volatility based on options freely traded in the open market as it 
believes this is more reflective of market conditions and a better indicator of expected volatility than using purely 
historical volatility.  The expected life of the awards is based on historical and other economic data trended into the 
future.  The risk-free interest rate assumption is based on observed interest rates appropriate for the expected terms 
of the Company's awards.  The dividend yield assumption is based on the Company's history and expectation of 
future dividend payouts.  The Company estimates the number of share-based awards which will be forfeited due to 
employee turnover.  Quarterly changes in the estimated forfeiture rate would affect share-based compensation, as the 
effect of adjusting the rate for all expense amortization after April 1, 2006 is recognized in the period the forfeiture 
estimate is changed.  If the actual forfeiture rate is higher than the estimated forfeiture rate, then an adjustment is 
made to increase the estimated forfeiture rate, which will result in a decrease to the expense recognized in the 
financial statements.  If the actual forfeiture rate is lower than the estimated forfeiture rate, then an adjustment is 
made to decrease the estimated forfeiture rate, which will result in an increase to the expense recognized in the 
financial statements.  If forfeiture adjustments are made, they would affect the Company's results of operations.  The 
effect of forfeiture adjustments in the years ended March 31, 2010, 2009 and 2008 was immaterial. 

The Company evaluates the assumptions used to value its awards on a quarterly basis.  If factors change and the 
Company employs different assumptions, share-based compensation expense may differ significantly from what was 
recorded in the past.  If there are any modifications or cancellations of the underlying unvested securities, the 
Company may be required to accelerate or increase any remaining unearned share-based compensation expense.  
Future share-based compensation expense and unearned share-based compensation will increase to the extent that 
the Company grants additional equity awards to employees or it assumes unvested equity awards in connection with 
acquisitions.   

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.  Investments in debt securities with original maturities of 
greater than six months consist primarily of AAA and AA rated financial instruments and counterparties.  The 
Company's investments are primarily in direct obligations of the U.S. government or its agencies, corporate bonds 
and in municipal bonds. 

F-10 

 
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 one distributor that accounted 
for 10% or more of its net sales in the year ended March 31, 2010.  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, as deemed necessary, may require collateral, primarily letters of credit.  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, 2010, 2009 and 2008.  See Note 17, Geographic and Other Information, for additional 
information on the Company's largest distributors. 

Distributor advances, included in deferred income on shipments to distributors in the consolidated balance 
sheets, totaled $57.5 million at March 31, 2010 and $37.6 million at March 31, 2009.  On sales to distributors, the 
Company's payment terms generally require the distributor to settle amounts owed to the Company for an amount in 
excess of their ultimate cost.  The Company's sales price to its distributors may be higher than the amount that the 
distributors will ultimately owe the Company because distributors often negotiate price reductions after purchasing 
the product from the Company and such reductions are often significant.  It is the Company's practice to apply these 
negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current 
basis, generally within 30 days, for amounts originally invoiced.  This practice has an adverse impact on the working 
capital of the Company's distributors.  As such, the Company has entered into agreements with certain distributors 
whereby it advances cash to the distributors to reduce the distributor's working capital requirements.  These 
advances are reconciled at least on a quarterly basis and are estimated based on the amount of ending inventory as 
reported by the distributor multiplied by a negotiated percentage.  Such advances have no impact on revenue 
recognition or the Company's consolidated statements of income.  The Company processes discounts taken by 
distributors against its deferred income on shipments to distributors' balance and trues-up the advanced amounts 
generally after the end of each completed fiscal quarter.  The terms of these advances are set forth in binding legal 
agreements and are unsecured, bear no interest on unsettled balances and are due upon demand.  The agreements 
governing these advances can be cancelled by the Company at any time. 

Use of Estimates 

The Company has made a number of estimates and assumptions relating to the reporting of assets, liabilities, 
revenues and expenses and the disclosure of contingent assets and liabilities to prepare its consolidated financial 
statements in conformity with U.S. Generally Accepted Accounting Principles.  Actual results could differ from 
those estimates. 

Adopted and Recently Issued Accounting Pronouncements  

Accounting Standards Codification.  Effective July 1, 2009, the Financial Accounting Standards Board's 

(FASB) Accounting Standards Codification (ASC) became the single official source of authoritative, 
nongovernmental generally accepted accounting principles (GAAP) in the United States.  The historical GAAP 
hierarchy was eliminated and the ASC became the only level of authoritative GAAP, other than guidance issued by 
the Securities and Exchange Commission.  The codification was effective for interim and annual reporting periods 
ending after September 15, 2009, except for certain nonpublic nongovernmental entities.  The Company's 
accounting policies were not affected by the conversion to ASC.  However, references to specific accounting 
standards in the footnotes to the Company's consolidated financial statements have been changed to refer to the 
appropriate section of ASC. 

Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion.  On April 1, 2009, 
the Company adopted the Cash Conversion Subsections of ASC Subtopic 470-20, Debt with Conversion and Other 
Options – Cash Conversion (the Cash Conversion Subsections), which clarify the accounting for convertible debt 
instruments that may be settled in cash (including partial cash settlement) upon conversion.  The Cash Conversion 
Subsections require issuers to account separately for the liability and equity components of certain convertible debt 
instruments in a manner that reflects the issuer's nonconvertible debt (unsecured debt) borrowing rate when interest 
cost is recognized.  The Cash Conversion Subsections require bifurcation of a component of the debt, classification 
of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of interest 
expense in the Company's consolidated statements of income. 

The Cash Conversion Subsections require retrospective application to the terms of instruments as they existed 

for all periods presented.  The adoption of the Cash Conversion Subsections affects the accounting for the 
Company's 2.125% junior subordinated convertible debentures issued in December 2007 and due in December 
2037.  The retrospective application of this guidance affects the Company's fiscal years 2008 and 2009.

The following table sets forth the effect of the retrospective application of the Cash Conversion Subsections on 

certain previously reported line items (in thousands, except per share data):

In addition, the adjustment resulted in changes to our consolidated statements of cash flows and Notes 10, 11, 

20 and 21. 

Other-Than-Temporary Impairments.  In April 2009, the FASB issued guidance changing existing guidance for 

determining whether an impairment of debt securities is other than temporary.  This guidance requires other than 
temporary impairments to be separated into the amount representing the decrease in cash flows expected to be 
collected from a security (referred to as credit losses) which is recognized in earnings and the amount related to 
other factors which is recognized in other comprehensive income.  This noncredit loss component of the impairment 
may only be classified in other comprehensive income if the holder of the security concludes that it does not intend 
to sell and it will not more likely than not be required to sell the security before it recovers its value.  If these 
conditions are not met, the noncredit loss must also be recognized in earnings.  When adopting this guidance, an 
entity is required to record a cumulative effect adjustment as of the beginning of the period of adoption to reclassify 
the noncredit component of a previously recognized other than temporary impairment from retained earnings to 
accumulated other comprehensive income.  The Company adopted this guidance on April 1, 2009.  The Company 
does not meet the conditions necessary to recognize the noncredit loss component of its auction rate securities in 
other comprehensive income.  Accordingly, the Company did not reclassify any previously recognized other-than-
temporary impairment losses from retained earnings to accumulated other comprehensive income and the adoption 
of this guidance had no impact on the Company's consolidated financial statements.  Refer to Note 4 for further 
discussion of the Company's investments in marketable securities.  

Fair-value when volume or level of activity has decreased significantly.  In April 2009, the FASB issued 
guidance for estimating fair value when the volume or level of activity in a market for an asset or liability has 
decreased significantly.  This guidance also provides information on identifying circumstances that indicate a  

F-12 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
transaction is not orderly (i.e., a forced liquidation or distressed sale). This guidance was effective for the Company 
beginning in fiscal 2010 and did not have a material impact on its financial position, results of operations or cash 
flows. 

Disclosures of fair value of financial instruments.  In April 2009, the FASB issued guidance that requires 
disclosures about fair value of financial instruments in interim financial statements.  This guidance was effective for 
the Company beginning in fiscal 2010, and because it applies only to financial statement disclosures, it had no 
impact on its financial position, results of operations or cash flows. 

Business combinations.  In December 2007, the FASB issued a revision to previously issued accounting 

literature which changes the accounting for business combinations including: (i) the measurement of acquirer shares 
issued in consideration for a business combination, (ii) the recognition of contingent consideration, (iii) the 
accounting for preacquisition gain and loss contingencies, (iv) the recognition of capitalized in-process research and 
development (IPR&D), (v) the accounting for acquisition-related restructuring costs, (vi) the treatment of 
acquisition-related transaction costs, and (vii) the recognition of changes in the acquirer's income tax valuation 
allowance.  The Company began applying this guidance prospectively to all business combinations beginning in 
fiscal 2010.  The impact of adoption on its financial position, results of operations or cash flows is dependent upon 
the nature and terms of business combinations that the Company consummates. 

2. 

BUSINESS ACQUISITIONS 

During the year ended March 31, 2010, the Company completed one business acquisition which was accounted 

for under the purchase method of accounting.  Total consideration paid for this business was approximately $9.3 
million.  The combined purchase price of the acquisition resulted in purchased intangible assets of approximately 
$7.0 million, of which $2.9 million relates to in-process technology, and goodwill of approximately $4.2 million.  
The purchased intangible assets (other than goodwill and the in-process technology intangible asset) are being 
amortized over an average period of seven years.  In addition, the acquisition resulted in contingent consideration 
with an estimated fair value at the date of purchase of $1.3 million. 

During the year ended March 31, 2009, the Company completed three business acquisitions which were 
accounted for under the purchase method of accounting.  Total consideration paid for these business acquisitions 
was approximately $19.9 million.  The combined purchase price of the acquisitions resulted in purchased intangible 
assets of approximately $15.1 million and goodwill of approximately $4.3 million.  The purchased intangible assets 
(other than goodwill) are being amortized over an average period of seven years.  One of the acquisitions has an 
earn-out payment associated with it based on the operating performance of the acquired business for the twelve-
month period ending September 30, 2010.  The initial purchase price of this acquisition was less than the fair value 
of the acquired net assets, and as a result, the Company recorded negative goodwill totaling $2.2 million, which is 
recorded in other long-term liabilities in the consolidated balance sheet. 

3. 

SPECIAL CHARGES 

Patent Licenses 

During the three months ended June 30, 2009, the Company agreed to the terms of a patent license with an 
unrelated third-party and signed an agreement on July 9, 2009.  The patent license settled alleged infringement 
claims.  The total payment made to the third-party in July 2009 was $1.4 million, $1.2 million of which was 
expensed in the first quarter of fiscal 2010 and the remaining $0.2 million was recorded as a prepaid royalty that will 
be amortized over the remaining life of the patent, which expires in June 2010. 

The Company entered into a patent portfolio license effective March 31, 2009 with an unrelated third-party that 
covers both issued patents and patent applications and settled alleged infringement claims.  The total payment made 
to the third-party was $8.25 million, $4.0 million of which was expensed in the fourth quarter of fiscal 2009 and the 
remaining $4.25 million was recorded as a prepaid royalty that will be amortized over the estimated 20-year 
remaining life of the patents. 

Expenses Associated with the Abandonment of the Atmel Acquisition  

On October 2, 2008, the Company and ON Semiconductor Corporation announced that they had sent a proposal 

to the Board of Directors of Atmel Corporation to acquire Atmel for $5.00 per share in cash or a total of 
approximately $2.3 billion.  On October 29, 2008, Atmel announced that its Board of Directors had determined that 
the unsolicited proposal was inadequate.  On December 15, 2008, the Company delivered a written notification to  

F-13 

 
Atmel regarding a proposed alternate slate of directors to be elected at Atmel's 2009 annual meeting.  On 
February 10, 2009, the Company announced its termination of its consideration of a potential transaction with Atmel 
in light of the economic uncertainty and the lack of visibility with respect to Atmel's business not allowing the 
Company to put a value on Atmel.  In the fourth quarter of fiscal 2009, the Company expensed $1.6 million of 
various costs associated with the terminated proposal. 

In-Process Research and Development 

During the third quarter of fiscal 2009, the Company completed its acquisition of Hampshire Company, a leader 

in the large format touch screen controller market.  As a result of the acquisition, the Company incurred a $0.5 
million in-process research and development charge in the third quarter of fiscal 2009. 

During the fourth quarter of fiscal 2009, the Company completed the acquisition of HI-TECH Software, a 
provider of software development tools and compilers.  As a result of the acquisition, the Company incurred a $0.2 
million in-process research and development charge in the fourth quarter of fiscal 2009. 

During the fourth quarter of fiscal 2009, the Company completed its acquisition of R&E International, a leader 

in developing innovative integrated circuits for smoke and carbon monoxide detectors and other life-safety systems.  
As a result of the acquisition, the Company incurred a $0.2 million in-process research and development charge in 
the fourth quarter of fiscal 2009. 

Loss on Sale of Fab 3 

The Company received an unsolicited offer on its Puyallup, Washington facility (Fab 3) in September 2007.  
The Company assessed its available capacity in its current facilities, along with potential available capacity from 
outside foundries and determined the capacity of Fab 3 would not be required in the near term.  As a result of this 
assessment, the Company accepted the offer on September 21, 2007, and the transaction closed on October 19, 
2007.  The Company received $27.5 million in cash, net of expenses associated with the sale, and recognized a loss 
on sale of $26.8 million, representing the difference between the carrying value of the assets and the amounts 
received.

The $58.4 million in marketable securities listed above relates to a strategic investment in Silicon Storage 
Technology, Inc. at $3.05 per share.  On April 8, 2010, the Company completed the acquisition of Silicon Storage 
Technology, Inc. for $3.05 per share in a merger transaction.  The Company has classified the shares owned in 
Silicon Storage Technology, Inc. as available-for-sale securities.   

Historically, the Company has made certain strategic investments in publicly traded companies which it 

classified as trading securities.  During the years ended March 31, 2010, 2009 and 2008, the Company recognized a 
gain in earnings of $7.5 million, a loss in earnings of $2.0 million and a gain in earnings of $0.5 million, 
respectively, on its trading securities.  During the years ended March 31, 2010, 2009 and 2008, the Company had 
realized gains of $1.1 million, $4.7 million and $0.2 million, respectively, on trading securities that it sold. 

At March 31, 2010, $37.2 million of the Company's investment portfolio was invested in ARS.  With the 
continuing liquidity issues in the global credit and capital markets, the Company's ARS have experienced multiple 
failed auctions.  In September 2007 and February 2008, auctions for $24.9 million and $34.8 million, respectively, 
of the original purchase value of the Company's investments in ARS first failed.  While the Company continues to 
earn interest on these investments based on a pre-determined formula with spreads tied to particular interest rate 
indices, the estimated market value for these ARS no longer approximates the original purchase value. 

The $24.9 million in failed auctions noted above have continued to fail through the filing date of this Annual 

Report on Form 10-K.  The fair value of the failed ARS of $14.2 million has been estimated based on market 
information and estimates determined by management and could change significantly based on future market 
conditions.  The Company evaluated the impairments in the value of these ARS, determining its intent to sell these 
securities prior to the recovery of its amortized cost basis resulted in the securities being other-than-temporarily 
impaired and recognized impairment charges on these investments of $3.6 million during fiscal 2009 and $4.7 
million in fiscal 2010, respectively. 

The $34.8 million of ARS that failed during February 2008 are investments in student loan-backed ARS 

(SLARS).  Approximately $2.9 million and $7.0 million of these SLARS were redeemed at par by the issuers during 
the fiscal years 2009 and 2010, respectively, reducing the Company's overall cost basis position in these SLARS to 
$24.9 million.  Based upon the Company's evaluation of available information, it believes these investments are of 
high credit quality, as all of the investments carry AAA credit ratings by one or more of the major credit rating 
agencies and are largely backed by the federal government (Federal Family Education Loan Program).  The fair 
value of the failed SLARS has been estimated based on market information and estimates determined by 
management and could change significantly based on future market conditions.   

In November 2008, the Company executed an ARS rights agreement (the Rights) with the broker through which 

the Company purchased the $24.9 million in SLARS that provides (1) the Company with the right to put these 
SLARS back to the broker at par anytime during the period from June 30, 2010 through July 2, 2012, and (2) the 
broker with the right to purchase or sell the SLARS at par on the Company's behalf anytime through July 2, 2012.  
The Company accounted for the acceptance of the Rights as the receipt of a put option for no consideration and 
recognized a gain with a corresponding recognition as a long-term investment.  The Company expects any future 
changes in the fair value of the SLARS to be largely offset by changes in the fair value of the related Rights without 
any significant net impact to the Company's income statement.  The Company will continue to measure the SLARS 
and the Rights at fair value (utilizing Level 3 inputs) until the earlier of maturity or exercise.  The Company intends 
and has the ability to hold the $24.9 million of SLARS until the market recovers or until June 30, 2010 when it has 
the right to sell the SLARS at par to the broker as it does not anticipate having to sell these securities to fund the 
operations of its business.  The Company believes that, based on its current unrestricted cash, cash equivalents and 
short-term investment balances, the current lack of liquidity in the credit and capital markets will not have a material 
impact on its liquidity, cash flow or ability to fund its operations. 

At March 31, 2010, the Company evaluated its investment portfolio, and noted unrealized losses of $0.9 million 

due to fluctuations in interest rates and credit market conditions.  Management does not believe any of the 
unrealized losses represent other-than-temporary impairment based on its evaluation of available evidence as of 
March 31, 2010.  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, 2010, such recovery is not 
anticipated to occur in the next year and these investments have been classified as long-term investments in the 
Company's consolidated balance sheets.  The amortized cost and estimated fair value of the available-for-sale 
securities at March 31, 2010, 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 available-for-sale securities as available for current operations.

FAIR VALUE MEASUREMENTS  

Accounting rules for fair value clarify that fair value is an exit price, representing the amount that would be 
received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  As such, 
fair value is a market-based measurement that should be determined based on assumptions that market participants 
would use in pricing an asset or liability.  As a basis for considering such assumptions, the Company utilizes a three-
tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1 – Observable inputs such as quoted prices in active markets; 

Level 2 – Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and 

Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to 

develop its own assumptions.

For Level 3 valuations, the Company estimated the fair value of these ARS based on the following: (i) the 
underlying structure of each security; (ii) the present value of future principal and interest payments discounted at 
rates considered to reflect current market conditions; (iii) consideration of the probabilities of default, auction 
failure, or repurchase at par for each period; and (iv) estimates of the recovery rates in the event of default for each 
security.  The Company estimated the value of the put option on the ARS by evaluating the estimated cash flows 
before and after the receipt of the put option, discounted at rates reflecting the likelihood of default and lack of 
liquidity, or in the case of the payment of the par value to be paid by the broker at exercise of the put option, the 
counterparty credit risk.  The estimated fair values that are categorized as Level 3 as well as the put options on 
publicly traded public stock could change significantly based on future market conditions. Refer to Note 4 for 
further discussion of the Company's investments in ARS.

Amortization expense attributed to intangible assets was $3.7 million, $2.7 million and $1.9 million for the 
years ending March 31, 2010, 2009 and 2008, respectively.  The Company did not record any impairment losses in 
the years ended March 31, 2010, 2009 and 2008 associated with the intangible assets acquired. 

Goodwill activity for the years ended March 31, 2010 and March 31, 2009 was as follows (amounts in 

thousands):

During fiscal 2009, the Company completed three acquisitions, which resulted in goodwill of approximately 

$4.3 million.  During fiscal 2010, the Company completed one acquisition, which resulted in goodwill of 
approximately $4.2 million.  

The Company has a single reporting unit, to which all of the goodwill at March 31, 2010 is assigned.   

After completing the annual impairment analyses during the fourth quarter of fiscal 2010, fiscal 2009 and fiscal 

2008, the Company concluded that goodwill was not impaired in any year.  At March 31, 2010, the Company has 
not recorded any impairment charges against its goodwill balance of approximately $40.3 million.

INCOME TAXES  

The Company is subject to income taxes in the U.S. and numerous foreign jurisdictions.  The Company files 
U.S. federal, U.S. state, and foreign income tax returns.  For U.S. federal, and in general for U.S. state tax returns, 
the 2006 through fiscal 2010 tax years remain open for examination by tax authorities.  For foreign tax returns, the 
Company is generally no longer subject to income tax examinations for years prior to fiscal 2002.  

Significant judgment is required in evaluating its uncertain tax positions and determining its provision for 

income taxes.  Although the Company believes that it has adequately reserved for its uncertain tax positions, no 
assurance can be given that the final tax outcome of these matters will not be different.  The Company will adjust 
these reserves in light of changing facts and circumstances, such as the closing of a tax audit, the refinement of an 
estimate, the closing of a statutory audit period or changes in applicable tax law.  To the extent that the final tax 
outcome of these matters is different than the amounts recorded, such differences will impact the provision for 
income taxes in the period in which such determination is made.  The provision for income taxes includes the impact 
of reserve provisions and changes to the reserves that are considered appropriate, as well as related net interest. 

The Company recognizes liabilities for anticipated tax audit issues in the U.S. and other domestic and 

international tax jurisdictions based on its estimate of whether, and the extent to which, additional tax payments are 
more likely than not.  The Company believes it maintains appropriate reserves to offset potential income tax 
liabilities that may arise upon final resolution of matters for open tax years.  The U.S. Internal Revenue Service 
(IRS) is currently auditing the Company's fiscal years 2006, 2007 and 2008.  Fiscal 2009 and fiscal 2010 are 
currently open for examination by the IRS.  The Company believes that it has appropriate support for the income tax 
positions taken and to be taken on its tax returns and that its accruals for tax liabilities are appropriate for all open 
years based on an assessment of many factors including past experience and interpretations of tax law applied to the 
facts of each matter.  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 

F-19 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
  
  
assessments ultimately prove to be greater than anticipated, a future charge to expense would be recorded in the 
period in which the assessment is determined.  Timing of the resolution and/or closure on audits is highly uncertain; 
however, the Company believes that it is reasonably possible that the unrecognized tax benefits could significantly 
change within the next 12 months as the result of a tax examination closure.  This settlement could have a significant 
impact on the unrecognized tax benefit; however the Company is not currently able to quantify the amount of such 
change.  

The following table summarizes the activity related to the Company's gross unrecognized tax benefits from 

April 1, 2009 to March 31, 2010 (amounts in thousands):

As of March 31, 2010, the Company had accrued approximately $4.7 million related to the potential payment of 

interest on the Company's uncertain tax positions.  Interest was included in the provision for income taxes.  The 
Company has not accrued any penalties related to its uncertain tax positions as the Company believes that it is more 
likely than not that there will not be any assessments of penalties.

The tax benefit associated with the Company's equity incentive plans reduced taxes currently payable by 

$3.7 million, $7.6 million and $21.9 million for the years ended March 31, 2010, 2009 and 2008, respectively.  
These amounts were credited to additional paid-in capital in each of the three fiscal years. 

The provision for income taxes differs from the amount computed by applying the statutory federal tax rate to

Pretax income from foreign operations was $201.2 million, $195.1 million and $273.1 million for the years 

ended March 31, 2010, 2009 and 2008, respectively.  Unremitted foreign earnings that are considered to be 
permanently invested outside the U.S., and on which no deferred taxes have been provided, amounted to 
approximately $1,277.9 million at March 31, 2010.  The Company has the ability and intent to indefinitely reinvest 
the foreign earnings.  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 effective tax rate in 
such periods.   

During the year ended March 31, 2010, the Company settled an IRS examination of fiscal years 2002, 2003 and 

2004 which resulted in a one-time tax benefit of $8.5 million.  This tax benefit decreased the Company's effective 
tax rate by approximately 3.6 percentage points to 8.8%. 

In October 2008, the U.S. Congress passed the Emergency Economic Stabilization Act of 2008 which included 

a provision to extend the research and development tax credit retroactively from January 1, 2008.  As a result, the 
Company recognized a one-time tax benefit of $1.5 million in the quarter ending December 31, 2008.  Likewise, the 
ongoing benefit from this credit was reflected in the Company's effective tax rate through December 31, 2009 when 
the research and development tax credit expired. 

During the year ended March 31, 2009, the Company settled an IRS examination of fiscal 2005 which resulted 

in a one-time tax benefit of $16.9 million.  Also, during fiscal 2009, the IRS issued revised Treasury Regulations 
that provided a clarification of the tax treatment of certain items that the Company had previously established a tax 
accrual for, and as a result, the Company recognized a $33.0 million tax benefit.  The tax reserve releases are 
reflected as separate line items in the rate reconciliation table above.  These tax benefits decreased the Company's 
effective tax rate by approximately 21.5 percentage points to an effective tax benefit of 5.8% for fiscal year 2009. 

During the year ended March 31, 2008, the Company realized a U.S. tax benefit of $10.3 million as a result of 
the sale of Fab 3 and realized a tax benefit of $11.0 million as the result of the release of previously established tax 
reserves consisting of approximately $5.7 million related to the resolution of a foreign tax matter in the third quarter 
of fiscal 2008, $4.5 million related to the release of tax reserves for certain international tax exposures in the fourth 
quarter of fiscal 2008 and approximately $0.8 million related to accrued interest and other reserve matters.  The tax 
reserve releases are reflected as a separate line in the rate reconciliation table above.  These tax benefits decreased 
the Company's effective tax rate for fiscal 2008 by approximately 4.4 percentage points to 15.1%. 

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and 

deferred tax liabilities are as follows (amounts in thousands): 

Deferred tax assets: 

Deferred intercompany profit  
Deferred income on shipments to distributors 
Inventory valuation

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, 2010, the Company had a net operating loss carryforward for federal income tax purposes of 

approximately $7.4 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 
limitation on the utilization of the PowerSmart net operating losses was performed in accordance with Internal 
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. 

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 in the future beginning in May 2010.  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 $17.3 million, $6.4 million and $7.1 million 
for the years ended March 31, 2010, 2009 and 2008, respectively.  The benefit the tax holiday had on diluted net 
income per share approximated $0.09 in the year ended March 31, 2010 and $0.03 for each of the years ended 
March 31, 2009 and 2008.

2.125% JUNIOR SUBORDINATED CONVERTIBLE DEBENTURES  

The Company's $1.15 billion principal amount of 2.125% junior subordinated convertible debentures due 

December 15, 2037, are subordinated in right of payment to any future senior debt of the Company and are 
effectively subordinated in right of payment to the liabilities of the Company's subsidiaries.  The debentures are 
convertible, subject to certain conditions, into shares of the Company's common stock at an initial conversion rate of 
29.2783 shares of common stock per $1,000 principal amount of debentures, representing an initial conversion price 
of approximately $34.16 per share of common stock.  As of March 31, 2010, none of the conditions allowing 
holders of the debentures to convert had been met.  As a result of cash dividends paid since the issuance of the 
debentures, the conversion rate has been adjusted to 32.9544 shares of common stock per $1,000 of principal 
amount of debentures, representing a conversion price of approximately $30.34 per share of common stock.   

As the debentures can be settled in cash upon conversion, for accounting purposes, the debentures were 

bifurcated into a liability component and an equity component, which are initially recorded at fair value.  The 
carrying value of the equity component at March 31, 2010 and at March 31, 2009 was $822.4 million.  The 
estimated fair value of the liability component of the debentures at the issuance date was $327.6 million, resulting in 
a debt discount of $822.4 million.  The unamortized debt discount was $808.7 million at March 31, 2010 and $815.0 
million at March 31, 2009.  The carrying value of the debentures was $340.7 million at March 31, 2010 and $334.2 
million at March 31, 2009.  The remaining period over which the unamortized debt discount will be recognized as 
non-cash interest expense is 27.75 years.  In the year ended March 31, 2010, the Company recognized $6.3 million 
in non-cash interest expense related to the amortization of the debt discount.  In the year ended March 31, 2009, the 
Company recognized $5.2 million in non-cash interest expense related to the amortization of the debt discount.  In 
the year ended March 31, 2008, the Company recognized $1.5 million in non-cash interest expense related to the 
amortization of the debt discount.  The Company recognized $24.4 million of interest expense related to the 2.125% 
coupon on the debentures in each of fiscal 2010 and fiscal 2009, and $7.1 million of interest expense related to the 
2.125% coupon on the debentures in fiscal 2008. 

The debentures also include certain embedded features related to the contingent interest payments, the 

Company making specific types of distributions (e.g., extraordinary dividends), the redemption feature in the event 
of changes in tax law, and penalty interest in the event of a failure to maintain an effective registration statement. 
These features qualify as derivatives and are bundled as a compound embedded derivative that is measured at fair 
value.  The fair value of the derivative as of March 31, 2010 was $0.7 million, compared to the value at March 31, 
2009 of $0.5 million, resulting in an increase of interest expense in fiscal 2010 of $0.2 million.  The balance of the 
debentures on the Company's condensed consolidated balance sheet at March 31, 2010 of $340.7 million includes 
the fair value of the embedded derivative.  

12. 

CONTINGENCIES  

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.  The Company periodically 
receives notification from various third parties alleging patent infringement of patents, intellectual property rights or 
other matters.  With respect to these and other pending legal actions to which Microchip is a party, although the 
outcome of these actions is not presently determinable, in the Company's opinion, based on consultation with legal 
counsel, as of March 31, 2010, it is not probable that the ultimate resolution of these matters will harm its business 
and will have a material adverse effect on its financial position, cash flows or results of operations.

STOCKHOLDERS' EQUITY 

Stock Repurchase Activity.  On December 11, 2007, the Company announced that its Board of Directors had 
authorized the repurchase of up to an additional 10.0 million shares of its common stock in the open market or in 
privately negotiated transactions.  As of March 31, 2010, the Company had repurchased 7.5 million shares under this 
authorization for $234.7 million.  There is no expiration date associated with this program.  

The Company's Board of Directors authorized the repurchase of 21.5 million shares of its common stock 
concurrent with the junior subordinated convertible debenture transaction for $638.6 million and no further shares 
are available to be repurchased under this authorization. 

During the year ended March 31, 2010, the Company did not purchase any of its shares of common stock.  

During the year ended March 31, 2009, the Company purchased 4.0 million shares of its common stock for 
$123.9 million.  During the year ended March 31, 2008, the Company purchased 36.5 million shares of its common 
stock for $1,138.0 million.   

As of March 31, 2010, approximately 33.5 million shares remained as treasury shares with the balance of the 

shares being used to fund share issuance requirements under the Company's equity incentive plans.  

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 IRS.  Through December 31, 2008, the Company made matching contributions of up to 
25% of the first 4% of the participant's eligible compensation and could award up to an additional 25% under the 
discretionary match.  The Company eliminated the mandatory matching contribution as of January 1, 2009.  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, 2009 and 2008, the Company contributions to the plan totaled 
$1.4 million and $1.4 million, respectively.  Due to expense reduction actions taken in response to adverse economic 
conditions, the Company did not contribute to the plan for the fiscal year ended March 31, 2010. 

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.  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 stock, or (iii) such lesser amount as is approved by the Company's Board of 
Directors.  On January 1, 2010, 921,171 additional shares were reserved under the 2001 Purchase Plan based on the 
automatic increase.  On January 1, 2009, 910,229 additional shares were reserved under the 2001 Purchase Plan 
based on the automatic increase.  On January 1, 2008, 945,068 additional shares were reserved under the 2001 
Purchase Plan based on the automatic increase.  Since the inception of the 2001 Purchase Plan, 9,376,063 shares of 
common stock have been reserved for issuance and 3,559,157 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 provided 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, 1,119,925 
shares of common stock have been reserved for issuance and 460,146 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. 

F-23 

 
The Company has management incentive compensation plans which provide 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, 2010, 2009 and 2008, $16.5 million, $3.0 million and 
$9.2 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, 2010, 
2009 and 2008, $4.3 million, $2.9 million and $2.3 million, respectively, were charged against operations for this 
plan. 

15. 

EQUITY INCENTIVE PLANS 

The Company has equity incentive plans under which incentive stock options, restricted stock units (RSUs) and 
non-qualified stock options have been granted to employees and under which non-qualified stock options and RSUs 
have been granted to non-employee members of the Board of Directors.  The Company's 2004 Equity Incentive 
Plan, as amended and restated (the 2004 Plan), is shareholder approved and permits the grant of stock options and 
RSUs to employees, non-employee members of the Board of Directors and consultants.  At March 31, 2010, 
8.2 million shares remained available for future grant under the 2004 Plan.  Stock options and RSUs are designed to 
reward employees for their long-term contributions to the Company and to provide incentive for them to remain 
employed with the Company.  The Company believes that such awards better align the interests of its employees 
with those of its shareholders.   

The Board of Directors or the plan administrator determines eligibility, vesting schedules and exercise prices for 

equity incentives granted under the plans.  Equity incentives granted generally have a term of 10 years.  Equity 
incentives granted in the case of newly hired employees generally vest and become exercisable at the rate of 25% 
after one year of service and ratably on a monthly or quarterly basis over a period of 36 months thereafter.  
Subsequent equity incentive grants to existing employees generally vest and become exercisable ratably on a 
monthly or quarterly basis over a period starting in 48 months and ending in 60 months after the date of grant.  
Beginning in fiscal 2008, the Company converted its equity granting practices to a quarterly process instead of an 
annual process.  The quarterly grants generally vest 48 months from the date of grant. 

Under the plans, 106,177,680 shares of common stock have been reserved for issuance since the inception of 

the plans.

The total intrinsic value of RSUs which vested during the year ended March 31, 2010 was $17.5 million.  The 
aggregate intrinsic value of RSUs outstanding at March 31, 2010 was $130.6 million calculated based on the closing 
price of the Company's common stock of $28.16 on March 31, 2010.   

The weighted average fair values per share of the RSUs awarded are calculated based on the fair market value 

of the Company's common stock on the respective grant dates discounted for the Company's expected dividend 
yield.  The weighted average fair values per share of RSUs awarded in the years ended March 31, 2010, 2009 and 
2008 was $20.75, $22.11 and $29.73, respectively.  At March 31, 2010, the weighted average remaining expense

GEOGRAPHIC AND OTHER 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, as deemed necessary, may require collateral, primarily letters of credit.  The Company's operations 
outside the U.S. 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 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 operations and other functions performed, and certain foreign sales offices receive 
compensation for sales within 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 property, plant and equipment) by geographic area are as follows (amounts in thousands):

approximately 77%, 75% and 75% of consolidated net sales for the years ended March 31, 2010, 2009 and 2008, 
respectively.  Sales to customers in Europe represented 25%, 29% and 30% of consolidated net sales for the years 
ended March 31, 2010, 2009 and 2008, respectively.  Sales to customers in Asia represented 51%, 46% and 44% of 
consolidated net sales for each of the years ended March 31, 2010, 2009 and 2008, respectively.  Sales into China, 
including Hong Kong, represented 25%, 23% and 20% of consolidated net sales for the years ended March 31, 
2010, 2009 and 2008, respectively.  Sales into Taiwan represented 10% of consolidated net sales for each of the

Company's net sales for any of the years presented. 

The Company had one distributor who represented more than 10% of its net sales during each of fiscal 2010, 

fiscal 2009 and fiscal 2008.  The Company's largest distributor accounted for approximately 12% of its net sales in 
fiscal 2010, approximately 14% of its net sales in fiscal 2009, and approximately 12% of its net sales in fiscal 2008.

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 the Company's junior subordinated convertible debentures 
was $1.146 billion at March 31, 2010, and $832.3 million at March 31, 2009 based on the trading price of the bonds. 

19. 

DERIVATIVE INSTRUMENTS 

The Company has international operations and is thus subject to foreign currency rate fluctuations.  To manage 
the risk of changes in foreign currency rates, the Company periodically enters into derivative contracts comprised of  
foreign currency forward contracts to hedge its asset and liability foreign currency exposure and a portion of its 
foreign currency operating expenses.  Approximately 99% of the Company's sales are U.S. Dollar denominated.  To 
date, the exposure related to foreign exchange rate volatility has not been material to the Company's operating 
results.  As of March 31, 2010 and 2009, the Company had no foreign currency derivatives outstanding.  The 
Company recognized an immaterial amount of net realized losses on foreign currency derivatives in the three 
months ended March 31, 2010.

Weighted average common shares exclude the effect of antidilutive options.  For the year ended March 31, 
2010, the number of option shares that were antidilutive were 4,109,841.  For the year ended March 31, 2009, the 
number of option shares that were antidilutive were 3,685,806.  For the year ended March 31, 2008, the number of 
option shares that were antidilutive were 127,219. 

Diluted net income per common share for the year ended March 31, 2010 does not include any incremental 
shares issuable upon the exchange of the debentures (see Note 11).  The debentures will have no impact on diluted 
net income per common share until the average price of the Company's common stock exceeds the conversion price 
because the principal amount of the debentures will be settled in cash upon conversion.  Prior to conversion, the 
Company will include, in the diluted net income per common share calculation, the effect of the additional shares 
that may be issued when the Company's common stock price exceeds the conversion price, using the treasury stock 
method.  The weighted average conversion price per share used in calculating the dilutive effect of the convertible 
debt for the year ended March 31, 2010 was $31.16.

DIVIDENDS 

On October 28, 2002, the Company announced that its Board of Directors had approved and instituted a 
quarterly cash dividend on its common stock.  The initial quarterly dividend of $0.02 per share was paid on 
December 6, 2003 in the amount of $4.1 million.  The Company has continued to pay quarterly dividends and has 
increased the amount of such dividends on a regular basis.  Cash dividends paid per share amounted to $1.359, 
$1.346 and $1.205 during the years ended March 31, 2010, 2009 and 2008, respectively.  Total dividend payments 
amounted to $249.6 million, $246.7 million and $252.0 million during the years ended March 31, 2010, 2009 and 
2008, respectively.

TRANSACTION WITH SILICON STORAGE TECHNOLOGY, INC. (SST) 

On February 2, 2010, the Company entered into an Agreement and Plan of Merger to acquire SST.  Subsequent 

to signing the initial Agreement and Plan of Merger, additional offers to acquire SST were made by third parties, 
and the Company entered into a First Amendment to the Agreement and Plan of Merger on February 22, 2010, and a 
Second Amendment to the Agreement and Plan of Merger on March 2, 2010 (the Second Amendment).  As part of 
the Second Amendment, the Company acquired 19.9% of the outstanding shares of SST through the purchase of 
newly issued shares of common stock at a price of $3.05 per share, the then fair value of the shares.  Additionally, as 
part of the Second Amendment, the Company agreed that in the event its offer to acquire SST at $3.05 per share was 
superseded by a superior offer by another party, the Company's profit on the shares, and the termination fee under 
the agreement would not exceed a threshold (the Profit Cap) established in the Second Amendment.  Any profits 
exceeding this threshold would be paid by the Company to SST in cash, or by remitting shares equal in value to the 
excess profits.  Finally, the Second Amendment gave the Company the right, but not the obligation, to require SST 
to repurchase the shares acquired (the 19.9% ownership shares), at a price of $3.05 per share in the event the 
acquisition was not completed (the Put Right).   

The Company accounted for the Profit Cap and Put Right as a compound embedded derivative, and valued this 

derivative taking into account the likelihood the derivative would become operable, since both the Profit Cap and 
the Put Right are contingent upon the acquisition of SST not occurring.  The Company concluded that the fair value 
of the derivative at the acquisition date and at March 31, 2010 were immaterial.  The Company has accounted for 
the investment in shares of SST as an available-for-sale security, and as the value of the shares at March 31, 2010 
was the same as that at the acquisition date, no unrealized gains or losses were recognized.  On April 8, 2010, the 
Company acquired the remaining outstanding shares of SST for $3.05 per share in a merger transaction as discussed 
below.

SUBSEQUENT EVENTS

$353.8 million, including the $58.4 million of SST shares acquired on March 8, 2010.  This business acquisition will 
be accounted for under the purchase method of accounting.  The Company is in the process of completing the 
purchase price allocation. 

On May 24, 2010, the Company consummated the sale of certain non-core assets from its SST acquisition.  The 

sale included inventory, equipment, intellectual property and certain other assets and liabilities associated with 
various product lines.
