INFORMATION REGARDING OUR COMPANY AND THE COMMON STOCK BEING SOLD IN THIS
OFFERING, INCLUDING "RISK FACTORS" AND OUR CONSOLIDATED FINANCIAL STATEMENTS AND
RELATED NOTES, INCLUDED ELSEWHERE IN THIS PROSPECTUS AND INCORPORATED BY

INTERNATIONAL RECTIFIER CORPORATION

We are a leading designer, manufacturer and marketer of power semiconductors
and the leading worldwide supplier of a type of power semiconductor called a
MOSFET, a metal oxide semiconductor field effect transistor. Power
semiconductors perform a power management function by converting electricity
into a form more usable by electrical products. The technology advancements of
power semiconductors increase system efficiency, allow more compact end
products, improve features and functionality and extend battery life. Our
products are used in a range of end markets, including communications, consumer
electronics, information technology, automotive, industrial and
government/space.

We use our proprietary technology, comprehensive knowledge of power
management, and low cost manufacturing platforms to offer what we believe is one
of the industry's most advanced and competitive lines of power semiconductors.
Our products are broadly divided among three product categories:

- POWER INTEGRATED CIRCUITS AND ADVANCED CIRCUIT DEVICES. A Power Integrated
Circuit, or Power IC, is a semiconductor that integrates logic and power
management functions on the same chip to optimize system performance.
Advanced Circuit Devices are chipsets, multichip modules and advanced
performance discrete devices that address power management requirements in
more demanding applications. Our Power ICs and Advanced Circuit Devices
reduce size, extend battery life and enhance the functionality of
electronic devices. These products provide application specific power
management solutions for wireless and wireline communication devices,
Internet infrastructure equipment and appliances, video game stations,
portable electronics, including personal digital assistants and notebook
computers, as well as automotive systems and motor control devices.

- POWER SYSTEMS. Power Systems combine power semiconductors with other power
management components in modules that improve power efficiency, provide a
cost-effective alternative to custom analog designs and enable customers
to introduce new products more quickly. We are focusing on Power Systems
for automotive electronics, including electric power steering and
integrated starter/alternator motors, as well as motor control
applications, including refrigeration and air conditioning.

- POWER COMPONENTS. Power Components are discrete devices used in general
power management applications. These include power MOSFETs, insulated gate
bipolar transistors, referred to as IGBTs, rectifiers, diodes and
thyristors. Power MOSFETs and IGBTs rapidly and efficiently switch
electricity on and off in order to supply power in a form that can be
formatted to the specific requirements of a circuit. Our power components
are used in virtually all of our end markets.

INDUSTRY OVERVIEW

3
<PAGE>
Within the power semiconductor market, MOSFETs and IGBTs are critical to power
management. Based on statistics published by the Semiconductor Industry
Association, industry-wide revenues from sales of power MOSFETs and IGBTs were
$3.13 billion in calendar 1999.

Demand for power semiconductors is being driven by the following:

- the growth of communications and Internet infrastructure;

- the increase in demand for portable electronics;

- the increasing applications in automotive electronics and motor controls;
and

- the recovery and expansion of Asian Pacific economies.

STRATEGY

We concentrate our resources on opportunities to add value and leverage our
competitive advantages through the following strategic initiatives:

FOCUS ON ADDING VALUE IN HIGH GROWTH MARKETS. We are leveraging our
leadership position in power semiconductors to offer proprietary products that
have higher average selling prices and gross margins in targeted applications.
Unlike most of our competitors, we focus all of our efforts in power
semiconductors. We believe this focus has resulted in our developing the most
advanced products for these markets. For example, our Power ICs are used in
power management for Intel's Pentium-Registered Trademark- III, AMD's
Athlon-Registered Trademark-, Motorola's cellular phones, and next generation
video game stations. In Power Systems, we are working with major automotive
suppliers in designing advanced systems to replace traditional hydraulic and
belt-driven applications with more cost-effective electronic systems that
improve performance and fuel efficiency. We are also targeting a wide range of
applications that have not historically utilized Power Systems, including
refrigerators, washing machines, air conditioners and other appliances.

EXTEND LEADERSHIP IN POWER COMPONENTS. The research firm Dataquest ranks us
as the world's leader in sales of MOSFETs. We pioneered the fundamental
technology that set the industry standard for power MOSFETs and estimate that
approximately 70% of the world's power MOSFETs are produced by us or use our
patented technology. Over the last two years, we have invested aggressively to
advance trench and planar process technologies. These investments have produced
what we believe are the most efficient power MOSFET components in the
marketplace. Our leadership position in Power Components provides us with a
platform for continued expansion in value-added growth markets.

CAPITALIZE ON LEADING CUSTOMER RELATIONSHIPS. As a result of our leadership
and strength in power semiconductors, industry leaders look to us for products
and programs that address their most challenging power management needs. These
relationships put us at the forefront of developing products for new trends in
the marketplace. We offer high quality customer service with comprehensive sales
and engineering support, including Internet service applications, electronic
order entry and just-in-time delivery. Our leading customers include Alcatel,
American Power Conversion, Compaq, Delphi, IBM, Lockheed-Martin, Lucent, Maxtor,
Mitsubishi, Motorola, Nortel Networks, Philips and Sony. In addition, our rate
of design wins has accelerated into the applications of these customers as well
as AMD, Bosch, Cisco Systems, Dell, Intel, Qualcomm and Groupe Schneider.

4
<PAGE>
the first quarter of fiscal 1998, we opened a new research and development
facility that provides submicron process capability and capacity for rapid
development. Our long-term investment in research and development has resulted
in a broad patent portfolio, consisting of 313 issued patents and 430 patents
pending. In fiscal 1999, licenses under our patents generated approximately
$26 million in royalties. We believe our technology leadership and product
innovation will continue to be a source of growth in the fastest growing
segments of the power semiconductor industry.

CAPITALIZE ON LOW COST MANUFACTURING. Unlike many of our competitors, we
fabricate most of our chips in facilities designed to address the specific
requirements of power semiconductors. We believe that our wafer fabrication
costs are among the lowest in the industry. We have production facilities in
California, England, Italy, Mexico, Wales, India and China. We also use
third-party foundries and assemblers to supplement our internal manufacturing.

We were founded in 1947 as a California corporation and reincorporated in
Delaware in 1979. Our principal executive offices are located at 233 Kansas
Street, El Segundo, California 90245 and our telephone number is (310)726-8000.

RECENT DEVELOPMENTS

On January 28, 2000, we announced an agreement with Zing
Technologies, Inc., to acquire all the outstanding shares of Zing for an
aggregate net cash purchase price of approximately $28.5 million. Zing's wholly
owned subsidiary and sole operating business, Omnirel LLC, manufactures and
sells high reliability power semiconductor systems, including multi-chip power
semiconductors, integrated power modules and packaged semiconductor components
for the military, and for industrial and high-end commercial markets. Omnirel's
products, customers, technology and manufacturing capabilities provide a
strategic complement to our own Power Systems business. Net sales for the
Omnirel operating unit of Zing for the fiscal year ended June 30, 1999 were
approximately $25 million. The acquisition is subject to certain conditions,
including the completion of the tender offer and the expiration of the waiting
period under federal antitrust laws.

(1) In fiscal 1997, we initiated a program to decrease costs through increased
yields, lower material costs and lower assembly and operating expenses. This
resulted in a $75.0 million special charge that included $61.0 million
related to asset write-downs, $10.0 million in severance costs and a
$4.0 million inventory write-down that reduced gross profit.

6
<PAGE>
$14.5 million special charge consisting of $5.9 million in severance costs,
$6.1 million for the write-down of related assets and a $2.5 million
inventory write-down that reduced gross profit.

(3) In addition to the assembly line relocation charge as noted above in (2), we
recorded a charge of $12.5 million in the second half of fiscal 1999
relating to additional severance charges for affected employees in sales,
customer service and administration.

(4) In fiscal 1999, other income (expense) included a $43.5 million pretax
benefit associated with the settlement of patent litigation recorded in the
second quarter of fiscal 1999 and other settlements of patent litigation in
the second half of fiscal 1999.

(5) We elected early adoption of Statement of Position 98-5, "Reporting on the
Costs of Start-Up Activities," which requires the expense of all start-up
and preoperating costs as they are incurred. The cumulative effect of this
change in accounting principle, net of tax benefit of $5.4 million, was
$26.2 million, which was recorded in the first quarter of fiscal 1999.

RISK FACTORS

BEFORE YOU INVEST IN OUR COMMON STOCK, YOU SHOULD CAREFULLY CONSIDER THE
RISKS DESCRIBED BELOW. YOU SHOULD ALSO REFER TO THE OTHER INFORMATION INCLUDED
IN THIS PROSPECTUS AND THE INFORMATION INCORPORATED IN THIS PROSPECTUS BY
REFERENCE, BEFORE YOU DECIDE TO INVEST IN OUR COMMON STOCK.

DOWNTURNS IN THE HIGHLY CYCLICAL SEMICONDUCTOR INDUSTRY OR CHANGES IN END MARKET
DEMAND COULD AFFECT OUR OPERATING RESULTS AND THE VALUE OF OUR BUSINESS.

The semiconductor industry is highly cyclical and the value of our business
may decline during the "down" portion of these cycles. During recent years, we,
as well as many others in our industry, experienced significant declines in the
pricing of our products. The pricing pressure in the semiconductor industry in
recent years was primarily due to the Asian currency crisis, industry-wide
excess manufacturing capacity and weak economic growth outside the United
States. Although markets for semiconductors have improved, we cannot assure you
that they will continue to improve or that our markets will not experience
renewed, possibly more severe and prolonged, downturns in the future. In
addition, we may experience significant changes in our profitability as a result
of variations in sales, changes in product mix, price competition for orders and
the costs associated with the introduction of new products. The markets for our
products depend on continued demand in the communications, consumer electronics,
information technology, automotive, industrial and government/space markets, and
these end markets may experience changes in demand that could adversely affect
our operating results and financial condition.

THE SEMICONDUCTOR BUSINESS IS HIGHLY COMPETITIVE AND INCREASED COMPETITION COULD
REDUCE THE VALUE OF AN INVESTMENT IN OUR COMPANY.

The semiconductor industry, including the segment in which we do business,
is highly competitive. Competition is based on price, product performance,
product availability, quality, reliability and customer service. In addition,
even in strong markets, price pressures may emerge as competitors attempt to
gain a greater market share by lowering prices. We compete in various markets
with companies of various sizes, many of which are larger and have greater
financial and other resources than we have, and thus may be better able to
pursue acquisition candidates and to withstand adverse economic or market
conditions. In addition, companies not currently in direct competition with us
may introduce competing products in the future.

NEW TECHNOLOGIES COULD RESULT IN THE DEVELOPMENT OF NEW PRODUCTS AND A DECREASE
IN DEMAND FOR OUR PRODUCTS, AND WE MAY NOT BE ABLE TO DEVELOP NEW PRODUCTS TO
SATISFY CHANGES IN DEMAND.

Our failure to develop new technologies or react to changes in existing
technologies could materially delay our development of new products, which could
result in decreased revenues and a loss of market share to our competitors.
Rapidly changing technologies and industry standards, along with frequent new
product introductions, characterize the semiconductor industry. Hence, we must
devote significant resources to research and development. Our financial
performance depends on our ability to design, develop, manufacture, assemble,
test, market and support new products and enhancements on a timely and
cost-effective basis. We cannot assure you that we will successfully identify
new product opportunities and develop and bring new products to market in a
timely and cost-effective manner, or that products or technologies developed by
others will not render our products or technologies obsolete or noncompetitive.
A fundamental shift in technologies in our product markets could have a material
adverse effect on our competitive position within the industry. In addition, to
remain competitive, we must continue to reduce die sizes and improve
manufacturing yields. We cannot assure you that we can accomplish these goals.

8
<PAGE>
OUR INTERNATIONAL OPERATIONS EXPOSE US TO MATERIAL RISKS.

In the six months ended December 31, 1999, our product sales by region were
41% in North America, 35% in Asia and 24% in Europe. We expect revenues from
foreign markets to continue to represent a significant portion of total
revenues. We maintain or contract with significant operations in the
Philippines, United Kingdom, Italy, Malaysia, China, Mexico, South Korea, India
and Taiwan. Among others, the following risks are inherent in doing business
internationally:

- changes in, or impositions of, legislative or regulatory requirements,
including tax laws in the United States and in the countries in which we
manufacture or sell our products;

- trade restrictions;

- transportation delays;

- work stoppages;

- economic and political instability; and

- foreign currency fluctuations.

In addition, the laws of certain foreign countries may not protect our products
or intellectual property rights to the same extent as do U.S. laws. Therefore,
the risk of piracy of our technology and products may be greater in these
foreign countries. Although we have not experienced any material adverse effect
on our operating results as a result of these and other factors, we cannot
assure you that such factors will not have a material adverse effect on our
financial condition and operating results in the future.

DELAYS IN BEGINNING PRODUCTION AT NEW FACILITIES, IMPLEMENTING NEW PRODUCTION
TECHNIQUES OR IN RESOLVING PROBLEMS ASSOCIATED WITH TECHNICAL EQUIPMENT
MALFUNCTIONS COULD ADVERSELY AFFECT OUR MANUFACTURING EFFICIENCIES.

Our manufacturing efficiency will be an important factor in our future
profitability, and we cannot assure you that we will be able to maintain or
increase our manufacturing efficiency to the same extent as our competitors. Our
manufacturing processes are highly complex, require advanced and costly
equipment and are continuously being modified in an effort to improve yields and
product performance. Impurities, defects or other difficulties in the
manufacturing process can lower yields.

In addition, as is common in the semiconductor industry, we have from time
to time experienced difficulty in beginning production at new facilities or in
effecting transitions to new manufacturing processes. As a consequence, we have
experienced delays in product deliveries and reduced yields. We may experience
manufacturing problems in achieving acceptable yields or experience product
delivery delays in the future as a result of, among other things, capacity
constraints, construction delays, upgrading or expanding existing facilities or
changing our process technologies, any of which could result in a loss of future
revenues. Our operating results could also be adversely affected by the increase
in fixed costs and operating expenses related to increases in production
capacity if revenues do not increase proportionately.

INTERRUPTIONS, DELAYS OR COST INCREASES AFFECTING OUR MATERIALS, PARTS OR
EQUIPMENT MAY IMPAIR OUR COMPETITIVE POSITION.

Our manufacturing operations depend upon obtaining adequate supplies of
materials, parts and equipment, including silicon, mold compounds and
leadframes, on a timely basis from third parties. Our results of operations
could be adversely affected if we were unable to obtain adequate supplies of
materials, parts and equipment in a timely manner or if the costs of materials,
parts or equipment increase significantly. From time to time, suppliers may
extend lead times, limit supplies or increase prices due to capacity constraints
or other factors. Although we generally use materials, parts and equipment
available from multiple suppliers, we have a limited number of suppliers for
some materials,

9
<PAGE>
parts and equipment. While we believe that alternate suppliers for these
materials, parts and equipment are available, an interruption could materially
impair our operations.

Also, some of our products are assembled and tested by third party
subcontractors. We do not have any long-term assembly agreements with these
subcontractors. As a result, we do not have immediate control over our product
delivery schedules or product quality. Due to the amount of time typically
required to qualify assemblers and testers, we could experience delays in the
shipment of our products if we are forced to find alternative third parties to
assemble or test them. Any product delivery delays in the future could have a
material adverse effect on our operating results and financial condition. Our
operations and ability to satisfy customer obligations could be adversely
affected if our relationships with these subcontractors were disrupted or
terminated.

OUR INTELLECTUAL PROPERTY IS ONE OF OUR PRINCIPAL ASSETS. PROTECTING THIS ASSET
MAY BE COSTLY AND UNCERTAIN.

We rely heavily on our patents and proprietary technologies. Patent
litigation settlements and royalty income substantially contribute to our
financial results. Enforcement of our intellectual property rights is costly,
risky and time-consuming. We cannot assure you that we can successfully continue
to protect our intellectual property rights, especially in foreign markets.

Our royalty income is largely dependent on the following factors:

- the remaining terms of our MOSFET patents;

- the defensibility and enforceability of our patents;

- the introduction and acceptance of power MOSFETs and IGBTs that are not
covered by our patents;

- changes in our licensees' unit sales, prices or die sizes; and

- the terms, if any, upon which expiring license agreements are
renegotiated.

Our key MOSFET patents expire between 2000 and 2010, with four such patents
expiring in year 2000, although our broadest patents expire in 2007 and 2008. In
addition, the U.S. Patent and Trademark Office is currently reexamining one of
our power MOSFET patents. We cannot assure you that this patent, or others that
may be subject to future reexamination, will be upheld.

We do not believe that the above reexamination or expiration of our MOSFET
patents in 2000 should result in a material decrease in our licensing revenues.
However, any decrease in our royalty income generally could have a material
adverse effect on our operating results and financial condition.

OUR FAILURE TO OBTAIN OR MAINTAIN THE RIGHT TO USE CERTAIN TECHNOLOGIES MAY
NEGATIVELY AFFECT OUR FINANCIAL RESULTS.

Our future success and competitive position may depend in part upon our
ability to obtain or maintain certain proprietary technologies used in our
principal products, which is achieved in part by defending claims by our
competitors of intellectual property infringement. We license certain patents
owned by others. We have also been notified that certain of our products may
infringe the patents of third parties. Although licenses are generally offered
in such situations, we cannot eliminate the risk of litigation alleging patent
infringement. While we are not currently engaged in intellectual property
litigation that we believe will have a material adverse effect, we could become
subject to lawsuits in which it is alleged that we have infringed upon the
intellectual property rights of others.

Our involvement in existing and future intellectual property litigation
could result in significant expense to us, adversely affect sales of the
challenged product or technologies and divert the efforts of our technical and
management personnel, whether or not such litigation is resolved in our favor.
If any such infringements exist, arise or are claimed in the future, we may be
exposed to substantial liability for damages and may need to obtain licenses
from the patent owners, discontinue or change our

10
<PAGE>
processes or products or expend significant resources to develop or acquire
non-infringing technologies. We cannot assure you that we would be successful in
such efforts or that such licenses would be available under reasonable terms.
Our failure to develop or acquire non-infringing technologies or to obtain
licenses on acceptable terms or the occurrence of related litigation itself
could have a material adverse effect on our operating results and financial
condition.

WE MUST COMMIT RESOURCES TO PRODUCT PRODUCTION PRIOR TO RECEIPT OF PURCHASE
COMMITMENTS AND COULD LOSE SOME OR ALL OF THE ASSOCIATED INVESTMENT.

We sell products primarily pursuant to purchase orders for current delivery,
rather than pursuant to long-term supply contracts. Many of these purchase
orders may be revised or canceled without penalty. As a result, we must commit
resources to the production of products without any advance purchase commitments
from customers. Our inability to sell products after we devote significant
resources to them could have a material adverse effect on our business,
financial condition and results of operations.

WE RECEIVE A SIGNIFICANT PORTION OF OUR REVENUES FROM A SMALL NUMBER OF
CUSTOMERS AND DISTRIBUTORS.

Historically, a significant portion of our revenues has come from a small
number of customers and distributors. For fiscal 1999 and the six months ended
December 31, 1999, our top five customers or distributors accounted for, in the
aggregate, approximately 27% and 27%, respectively, of our total revenues. The
loss or financial failure of any significant customer or distributor, any
reduction in orders by any of our significant customers or distributors, or the
cancellation of a significant order, could materially and adversely affect our
business.

WE MAY FAIL TO ATTRACT OR RETAIN THE QUALIFIED TECHNICAL, SALES, MARKETING AND
MANAGERIAL PERSONNEL REQUIRED TO OPERATE OUR BUSINESS SUCCESSFULLY.

Our future success depends, in part, upon our ability to attract and retain
highly qualified technical, sales, marketing and managerial personnel. Personnel
with the necessary semiconductor expertise are scarce and competition for
personnel with these skills is intense. We cannot assure you that we will be
able to retain existing key technical, sales, marketing and managerial employees
or that we will be successful in attracting, assimilating or retaining other
highly qualified technical, sales, marketing and managerial personnel in the
future. If we are unable to retain existing key employees or are unsuccessful in
attracting new highly qualified employees, our business, financial condition and
results of operations could be materially and adversely affected.

WE ARE ACQUIRING AND MAY CONTINUE TO ACQUIRE OTHER COMPANIES AND MAY BE UNABLE
SUCCESSFULLY TO INTEGRATE SUCH COMPANIES WITH OUR OPERATIONS.

We recently announced our intention to acquire Zing Technologies, Inc. and
we may continue to expand and diversify our operations with additional
acquisitions. If we are unsuccessful in integrating these companies with our
operations, or if integration is more difficult than anticipated, we may
experience disruptions that could have a material adverse effect on our
business, financial condition and results of operations. Some of the risks that
may affect our ability to integrate or realize any anticipated benefits from
companies we acquire include those associated with:

- unexpected losses of key employees or customers of the acquired company;

- conforming the acquired company's standards, processes, procedures and
controls with our operations;

- coordinating our new product and process development;

- hiring additional management and other critical personnel; and

- increasing the scope, geographic diversity and complexity of our
operations.

11
<PAGE>
OUR PRODUCTS MAY BE FOUND TO BE DEFECTIVE, PRODUCT LIABILITY CLAIMS MAY BE
ASSERTED AGAINST US AND WE MAY NOT HAVE SUFFICIENT LIABILITY INSURANCE.

One or more of our products may be found to be defective after we have
already shipped the products in volume, requiring a product replacement or
recall. We may also be subject to product returns that could impose substantial
costs and have a material and adverse effect on our business, financial
condition and results of operations.

Product liability claims may be asserted with respect to our products.
Although we currently have product liability insurance, we cannot assure you
that we have obtained sufficient insurance coverage or that we will have
sufficient resources to satisfy any product liability claims.

AN ADVERSE RULING OR DECISION IN A PENDING TRIAL COULD MATERIALLY IMPAIR OUR
FINANCIAL POSITION.

Our directors and some of our officers are defendants in three lawsuits in
California that allege intentional and negligent misrepresentations and
violations of the federal securities laws in connection with our public offering
of common stock in April 1991 and the redemption in June 1991 of our 9%
convertible subordinated debentures. The suits also allege that our projections
for growth in fiscal 1992 were materially misleading. Although some of the
claims have been dismissed and we believe that the remaining allegations in
these lawsuits are without merit, we cannot presently determine the final
outcome of these lawsuits. A substantial judgment or settlement, if any, could
have a material adverse effect on our operating results and financial condition.
Trial of the remaining claims is scheduled for March 14, 2000.

LARGE POTENTIAL ENVIRONMENTAL LIABILITIES, INCLUDING THOSE RELATING TO A FORMER
OPERATING SUBSIDIARY, MAY ADVERSELY IMPACT OUR FINANCIAL POSITION.

Federal, state and local laws and regulations impose various restrictions
and controls on the discharge of materials, chemicals and gases used in our
semiconductor manufacturing processes. In addition, under some laws and
regulations, we could be held financially responsible for remedial measures if
our properties are contaminated or if we send waste to a landfill or recycling
facility that becomes contaminated, even if we did not cause the contamination.
Also, we may be subject to common law claims if we release substances that
damage or harm third parties. Further, we cannot assure you that changes in
environmental laws or regulations will not require additional investments in
capital equipment or the implementation of additional compliance programs in the
future. Any failure to comply with environmental laws or regulations could
subject us to serious liabilities and could have a material adverse effect on
our operating results and financial condition.

We and Rachelle Laboratories, Inc., a former operating subsidiary that
discontinued operations in 1986, were each named a potentially responsible party
in connection with the investigation by the U.S. Environmental Protection Agency
of the disposal of allegedly hazardous substances at a major superfund site in
Monterey Park, California, known as the OII Site. Although we have settled all
outstanding claims that have arisen out of this site, no claims against Rachelle
have been settled.

We received a letter dated July 25, 1995 from the U.S. Department of
Justice, directed to Rachelle, offering to settle claims against Rachelle
relating to the first elements of clean-up work at the OII Site for $4,953,148.
The offer stated that the settlement would not cover the cost of any additional
remedial actions required to finish the clean-up. This settlement offer expired
by its terms on September 1, 1995. On August 7, 1995, we received a Supplemental
Information Request from the EPA directed to Rachelle, to which counsel for
Rachelle responded with information regarding waste shipped to the site. Counsel
for Rachelle received a letter from the EPA dated September 30, 1997, requesting
that Rachelle participate in the final remedial actions at the site, and counsel
replied on October 21, 1997. We have taken the position that none of the wastes
generated by Rachelle were hazardous. Neither we nor Rachelle have received any
further communications from the EPA in connection with this site.

12
<PAGE>
We cannot presently determine with accuracy the amount of the potential
demand to Rachelle for the cost of the final remedy. Based upon information
received to date, we believe that any demand for the cost of the final remedy,
if made, would not likely be material to our financial condition although it
could affect our results of operations and cash flows. Any demands related to
the cost of the final remedy would be in addition to the amount demanded for
earlier phases of the OII Site clean-up. Our insurer has not yet accepted
liability although it has made payments for defense costs we have incurred in
connection with the lawsuit.

SOME OF OUR FACILITIES ARE LOCATED NEAR MAJOR EARTHQUAKE FAULT LINES.

Our corporate headquarters, our major manufacturing facility, our research
facility and certain other critical business operations are located near major
earthquake fault lines. We could be materially and adversely affected in the
event of a major earthquake. Although we maintain earthquake insurance, we can
give you no assurance that we have obtained or will maintain sufficient
insurance coverage.

DELAWARE LAW AND OUR CHARTER DOCUMENTS CONTAIN PROVISIONS THAT COULD DISCOURAGE
OR PREVENT A POTENTIAL TAKEOVER OF OUR COMPANY THAT MIGHT OTHERWISE RESULT IN
OUR STOCKHOLDERS RECEIVING A PREMIUM OVER THE MARKET PRICE OF THEIR SHARES.

Provisions of Delaware law and our certificate of incorporation and bylaws
could make more difficult the acquisition of our company by means of a tender
offer, a proxy contest, or otherwise, and the removal of incumbent officers and
directors. These provisions include:

- Section 203 of the Delaware General Corporation Law, which prohibits a
merger with a 15%-or-greater stockholder, such as a party that has
completed a successful tender offer, until three years after that party
became a 15%-or-greater stockholder;

- our board of directors is divided into three classes with staggered three
year terms for each class, which could make it more difficult to gain
control of our board of directors;

- the authorization in the certificate of incorporation of undesignated
preferred stock, which could be issued without stockholder approval in a
manner designed to prevent or discourage a takeover; and

- provisions in our bylaws eliminating stockholders' rights to call a
special meeting of stockholders, which could make it more difficult for
stockholders to wage a proxy contest for control of our board or to vote
to repeal any of the anti-takeover provisions contained in our certificate
of incorporation and bylaws.

USE OF PROCEEDS

We will receive estimated net proceeds of approximately $287 million from
the sale of shares of common stock in this offering, after deducting
underwriting discounts and estimated offering expenses, and assuming a public
offering price of $39 13/16 per share. We expect to use the net proceeds of this
offering to:

- repay all of the indebtedness outstanding under our secured credit
agreement (approximately $152 million); and

- provide funds for general corporate purposes, including capital
expenditures and possible acquisitions.

Indebtedness under our secured credit agreement accrues interest at variable
rates and must be repaid in full in 2004 and 2005. At December 31, 1999, the
weighted average interest rate on secured credit agreement borrowings was 9.5%.
We intend to terminate the secured credit agreement after this offering.

Pending use of the net proceeds as described above, we will invest the net
proceeds in investment grade, marketable securities.

PRICE RANGE OF COMMON STOCK

Our common stock is traded on The New York Stock Exchange and the Pacific
Exchange under the symbol "IRF". The following table sets forth for the quarters

(1) In fiscal 1997, we initiated a program to decrease costs through increased
yields, lower material costs, and lower assembly and operating expenses.
This resulted in a $75.0 million special charge that included $61.0 million
related to asset write-downs, $10.0 million in severance costs, and a
$4.0 million inventory write-down that reduced gross profit.

(2) In the quarter ended December 31, 1998, we decided to relocate assembly
lines from our facility in England to our facility in Mexico and to
streamline worldwide sales and administration through reductions in
personnel. These plans resulted in a $14.5 million special charge consisting
of $5.9 million in severance costs and $6.1 million for the write-down of
related assets, and a $2.5 million inventory write-down that reduced gross
profit.

(3) In addition to the assembly line relocation as noted above in (2), we
recorded a charge of $12.5 million in the second half of fiscal 1999
relating to additional severance charges for affected employees in sales,
customer service and administration.

(6) Certain reclassifications have been made to previously reported amounts to
conform to current period presentation.

- ------------------------------

(1) In the quarter ended December 31, 1998, we decided to relocate assembly
lines from our facility in England to our facility in Mexico and to
streamline worldwide sales and administration through education in
personnel. These plans resulted in a $14.5 million special charge, which
included a $12.0 million restructuring charge consisting of $5.9 million in
severance costs and $6.1 million for the write-down of related assets, and a
$2.5 million in inventory write-down that reduced gross profit.

(2) We recorded a charge of $4.2 million relating to severance charges for
affected employees in sales, customer service and administration in third
quarter of fiscal 1999.

(3) We recorded an additional charge of $8.3 million relating to severance
charges for affected employees in sales, customer service and administration
in the fourth quarter of fiscal 1999.

SIX MONTHS ENDED DECEMBER 31, 1999 COMPARED WITH THE SIX MONTHS ENDED
DECEMBER 31, 1998

Our revenues for the six-month period ended December 31, 1999 increased
24.2% to $323.3 million from $260.3 million for the six month period ended
December 31, 1998. The revenue increase reflected strong demand in portable and
consumer electronics, computers and servers. Revenues in the six-month period
ended December 31, 1999 included $15.1 million of net patent royalties, versus
$11.1 million in the comparable prior-six-month period, reflecting a number of
new license agreements and market growth.

For the six months ended December 31, 1999, our product sales by region
(based on the location of the customer) were approximately 36% from North
America, 24% from Europe and 40% from Asia, which includes Japan and Asia
Pacific, compared to 41%, 26% and 33%, respectively, for the six months ended
December 31, 1998. Revenue in Asia Pacific grew 54% over the six months ended
December 31, 1998, reflecting the continued move of American and European
manufacturing activities to this region as well as strong demand in all sectors.
The 26% growth of year-to-year revenue from Japan reflects strong demand for
proprietary products and improved market conditions. Europe remains stable with
continuing strength in the automotive and cellular phone industries. North
America sales remained constant, despite the impact of certain customers moving
assembly from the U.S. to Asia. Unit shipments increased 49% period to period.

Gross profit for the six-month period ended December 31, 1999 increased to
$106.4 million (32.9% of revenues) from $72.4 million (27.8% of revenues) for
the six months ended December 31, 1998. The gross margin increase reflected a
higher proportion of revenue from proprietary products, lower manufacturing
costs as a result of continued manufacturing efficiencies and restructuring
efforts, and firm pricing. During December 1998, we charged $2.5 million to the
cost of goods sold due to the write-down of inventory as a result of the planned
relocation of assembly lines from our facility in

19
<PAGE>
England to our facility in Mexico. Excluding the inventory charge, gross profit
for the six-month period ended December 31, 1998 was 28.8% of revenue. See
"Impairment of Assets, Restructuring and Severance Charges" below.

In the six-month period ended December 31, 1999, selling and administrative
expense was $53.7 million (16.6% of revenues), versus $48.6 million (18.7% of
revenues) in the comparable year-ago period. The reduction in the ratio of
selling and administrative expense to revenues reflects the results of ongoing
initiatives to increase the productivity of selling and administrative
activities and the benefit of restructuring programs. We expect selling and
administrative expense as a percentage of revenues to decrease with rising
sales.

In the six-month period ended December 31, 1999, our research and
development expenditures increased to $21.7 million (6.7% of revenues), compared
to $20.4 million (7.8% of revenues) in the comparable prior-year period. We
anticipate an increased level of research and development expenditures to
accelerate the development of new products.

Other income was $0.6 million in the first half of fiscal 2000 versus other
income of $44.3 million in the comparable prior-year period. During the second
quarter of fiscal 1999, we recorded a $43.5 million pretax benefit related to
the settlement of patent litigation. The income reported from these settlements
was net of advanced and deferred royalty payments, patent defense costs, and the
share of our royalty proceeds payable to Unitrode Corporation.

Net interest expense increased $2.0 million in the six-month period ended
December 31, 1999, compared to the respective prior-year period. This increase
reflects higher interest rates and the terms of the new credit agreement that we
entered into at the end of the fourth quarter of fiscal 1999.

Our net realized and unrealized foreign currency gains and losses were less
than $1.0 million in each six-month period.

In fiscal 1999, we reported a non-cash, after-tax charge of $26.2 million
associated with the early adoption of Statement of Position ("SOP") 98-5, a
mandated change in accounting practices for certain start-up and preoperating
costs. The cumulative effect of this accounting change was recorded
retroactively to the first quarter of fiscal 1999 as a one-time charge. We had
previously deferred and amortized such costs.

FISCAL YEAR 1999 COMPARED WITH FISCAL YEAR 1998

Fiscal 1999 was a 52-week year compared to a 53-week year in fiscal 1998.
Revenues for fiscal 1999 were $545.4 million, slightly lower than fiscal 1998
revenue of $551.9 million. Net patent royalties contributed $26.5 million to
revenue, compared to $17.2 million in the prior period. During fiscal 1999, our
global pricing averaged an 8% decline on a same mix basis in fiscal 1999 versus
1998, compared to a 14% decline in fiscal 1998 versus 1997.

In fiscal 1999, our product sales by region, based on the location of the
customer, were approximately 42% from North America, 24% from Europe and 34%
from Asia, which includes Japan and Asia Pacific, compared to 47%, 26% and 27%,
respectively, in fiscal 1998. Year-to-year revenue in Japan decreased by 8.5%
but increased in Asia Pacific by 35.4%, reflecting a partial economic recovery
and our penetration into new market segments in the Asian market. Europe was
down 10.1% year-to-year, with weakness in most market segments. Revenue in North
America decreased 12.4% year-to-year, reflecting distributors' efforts to reduce
their inventories and the shift of some U.S. based customers' assembly
operations to locations in Asia.

Unit shipments increased 28% year-to-year. The revenue comparison over the
same period reflects price pressure and a shift to smaller, lower-priced
products, particularly in Asian markets.

20
<PAGE>
Gross profit was $152.0 million (27.9% of revenues) in fiscal 1999, versus
$176.2 million (31.9% of revenues) in fiscal 1998. The year-to-year gross profit
comparison reflected intense industry-wide price declines, unfavorable
fluctuations in product mix, and certain other expenses: a $2.5 million
inventory write-down associated with the transfer of manufacturing lines as part
of a restructuring program, and $2.7 million related to the adoption of
Statement of Position 98-5, "Reporting on the Costs of Start-up Activities".
Total cost of sales reflected the substantial increase in unit shipments to meet
rising demand.

In an effort to offset price pressure, we substantially reduced unit costs
and achieved approximately $53.0 million in manufacturing cost reductions in
fiscal 1999. Cost reduction measures included re-negotiation of prices paid for
materials and subcontract manufacturing services and process changes that
benefited manufacturing yields, as well as increased utilization of our
production capacity.

Selling and administrative expense was $98.2 million (18.0% of revenues) in
fiscal 1999 versus $104.7 million (19.0% of revenues) in fiscal 1998. The
improvement in absolute dollars and as a percent of sales reflects initiatives
to increase the productivity of selling and administrative activities as well as
the benefit of restructuring programs.

In fiscal 1999, research and development expenditures increased
$1.4 million to $40.5 million (7.4% of revenues) from $39.1 million (7.1% of
revenues) in the prior period. Higher research and development expenses for
fiscal 1999 reflect accelerated development of new products, as well as higher
overhead costs associated with a new research and development facility. We
expect this increased development activity to yield significant new products.

Other income was $53.5 million in fiscal 1999, compared to other expense of
$0.5 million in fiscal 1998. Other income primarily consisted of proceeds from
license agreements for prior periods and amounts in settlement of litigation for
past patent infringement (net of legal costs and the share of our royalty
proceeds payable to Unitrode Corporation).

In fiscal 1999, our net interest expense increased $3.8 million from the
prior year. The increase was due to higher interest expense incurred on higher
average debt balances over the prior year, which were partially offset by
increases in interest income on investments.

We reported a non-cash, after-tax charge of $26.2 million associated with
the early adoption of SOP 98-5, an AICPA-mandated change in accounting practices
for certain start-up and preoperating costs. We had previously deferred and
amortized such costs.

Our net realized and unrealized foreign currency gains and losses were less
than $1 million in each year.

FISCAL YEAR 1998 COMPARED WITH FISCAL YEAR 1997

Fiscal 1998 was a 53-week year compared to a 52-week year in fiscal 1997.
Our revenues for fiscal 1998 increased 14% to $551.9 million from
$486.1 million in the prior year. Unit shipments increased 38 percent, but the
revenue increase was partially offset by a $12.3 million unfavorable fluctuation
in currency exchange rates and an approximate average 14% price reduction on our
products on a same mix basis. The price decline reflected the impact of Asian
economic conditions and efforts by customers and distributors to reduce channel
inventories. Net patent royalties contributed $17.2 million to our revenue,
compared to $20.3 million in the prior period. Royalties are based on licensees'
sales of products covered by our patents, which we believe declined as a result
of economic and business conditions, currency exchange rates and fluctuations in
product mix.

Gross profit was $176.2 million (31.9% of revenues) in fiscal 1998 versus
$163.1 million (33.5% of revenues) in fiscal 1997. The gross profit decline
reflects pricing and market conditions described above. During the fourth
quarter of fiscal 1997, we recorded a $75.0 million pre-tax charge related to a

21
<PAGE>
restructuring program designed to improve its competitive position and
accelerate growth and earnings by streamlining operations and administration.

Selling and administrative expense was $104.7 million (19.0% of revenues) in
fiscal 1998 versus $106.0 million (21.8% of revenues) in fiscal 1997. Reductions
in selling and administrative expenses reflect our continued efforts to control
spending and to administer its activities more efficiently.

In fiscal 1998, our research and development expenditures increased
$3.6 million to $39.1 million (7.1% of revenues) from $35.5 million (7.3% of
revenues) in the prior period. Higher research and development expenses reflect
higher overhead costs associated with a new research and development facility
and our increased development of new products.

In fiscal 1998, our net interest expense increased $3.3 million from the
prior year. The increase was due to higher interest expense incurred on higher
average debt balances over the prior year, which were partially offset by small
increases in interest income on investments and interest capitalized on
construction-in-progress.

Our net realized and unrealized foreign currency gains and losses were less
than $1 million in each year.

SEASONALITY

We have experienced moderate seasonality in our business in recent years. On
average over the past three years, we have reported approximately 48% of annual
revenues in the first half and 52% in the second half of our fiscal year.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 1999, we maintained cash and cash equivalent balances of
$30.0 million. During the six-month period ended December 31, 1999, operating
activities generated cash flow of $23.3 million.

Net investing activities consumed $16.4 million, primarily due to capital
expenditures of $23.3 million, offset in part by the liquidation of short-term
investments. At December 31, 1999, we had made purchase commitments for capital
expenditures of approximately $18.8 million. Assuming existing market
conditions, we plan fiscal 2000 capital investments of approximately
$75 million, principally for fabrication and assembly capacity to meet market
demand. We intend to fund capital expenditures and working capital requirements
through cash and cash equivalents on hand, anticipated cash flow from
operations, and, as needed, from funds available from a revolving credit
facility or the proceeds of this offering.

Cash used in financing activities consumed $8.8 million. In June 1999, we
entered into a syndicated credit agreement with Banque Nationale de Paris. The
credit agreement consists of two term loans totaling $155 million due in 2004
and 2005 and a $70 million revolving line of credit. The proceeds from the term
loans were used to pay down all of our existing long-term unsecured bank loans
and substantially all domestic bank loans. As of December 31, 1999,
$152.1 million was outstanding under these two term loans and no borrowings have
occurred against the $70 million revolving line of credit. The interest rate on
these two term loans is based on 3.0% to 3.5% above the applicable LIBOR rate
and 2.0% to 2.5% above the applicable base rate. The base rate applies to
borrowings which are shorter than 30 days. The loans are collateralized by the
majority of our assets. The credit agreement subjects us to a number of
restrictive covenants, including the following:

- maximum leverage, minimum interest coverage and fixed charge coverage
ratios;

- minimum EBITDA (earnings before interest, taxes, depreciation and
amortization);

22
<PAGE>
- maximum capital expenditures; and

- a limitation on losses.

The credit agreement also contains restrictions with respect to the payment
of cash dividends, the sale of assets, mergers and acquisitions, additional
financing, and investments. At December 31, 1999, we also had $20.4 million in
foreign revolving lines of credit, against which $13.5 million had been
borrowed. We fully utilized foreign term loan facilities of $3.6 million and
equipment financing facilities of $4.8 million. In total, as of December 31,
1999, we had credit facilities of $250.9 million, against which we had borrowed
$174.1 million.

We intend to pay off and terminate the credit agreement with a portion of
the net proceeds from this offering. We currently estimate that the termination
of the credit agreement will result in an extraordinary charge of $3.8 million
after taxes which will be reflected in the fiscal quarter in which the credit
agreement is terminated.

Based on cash and cash equivalents on hand and our unused credit facilities,
at December 31, 1999, our liquidity was $106.9 million.

We anticipate that our operating cash flow, funds from this offering and
cash and cash equivalents will be sufficient to meet our anticipated future
working capital, capital expenditures and interest service requirements on our
debt obligations. Although we believe that funding will be sufficient, we may
also consider the use of funds from other external sources including, but not
limited to, public or private offerings of debt or equity.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to various risks including changes in interest rates
affecting the repayment of debt and return on investments and foreign currency
rate fluctuations. We do not hold or purchase any foreign currency or interest
rate contracts for trading purposes. Our objective in managing the exposure to
foreign currency changes is to reduce the risk to earnings and cash flow by
entering into forward exchange contracts that are intended to reduce risks
associated with the value of its existing foreign currency assets, liabilities,
firm commitments and anticipated foreign revenues and costs. The gains and
losses on these contracts are intended to offset changes in the related
exposures. We do not hedge our foreign currency exposure in a manner that would
entirely eliminate the effects of changes in foreign exchange rates on our
consolidated net income.

In the normal course of business, we also face risks that are either
nonfinancial or nonquantifiable. Such risks principally include country risk,
credit risk and legal risk and are not discussed or quantified in the following
analyses.

INTEREST RATE RISK

Our financial assets are not subject to significant interest rate risk due
to their short duration. Our financial liabilities that are subject to interest
rate risk are our long-term debt obligations. A 70 basis-point increase in
interest rates (approximately 10% of our weighted average interest rate on debt)
affecting our financial instruments would have an immaterial effect on our
results of operations, financial position or cash flows. Our credit agreement
with Banque Nationale de Paris requires us to hedge the interest rate for at
least half of the $152.1 million in outstanding term loans under the agreement.
We have entered into interest rate swap agreements to hedge 50% of these
outstanding term loans. The purpose of these swaps is to offset with a fixed
interest rate a portion of the risk inherent in this variable rate debt. Under
these agreements, we will pay the counterparties (the parties assuming the
interest rate risk) interest at a weighted average fixed rate of 6.2% and the
counterparties will pay us interest at a variable rate equal to LIBOR. The
weighted average three-month LIBOR rate applicable to these agreements was 6.2%
at December 31, 1999.

23
<PAGE>
FOREIGN CURRENCY RISK

We conduct business in various parts of the world and in various foreign
currencies. We manage potential foreign currency exposure by entering into
forward foreign exchange contracts or other non-speculative risk management
instruments to hedge foreign currency denominated receivables and payables at
certain of our international subsidiaries. At December 31, 1999, we evaluated
the effect that near-term changes in foreign exchange rates would have had on
the fair value of our combined foreign currency position, related to our
outstanding foreign currency forward exchange contracts. If we assumed an
adverse change of 10% in foreign exchange rates, the potential decrease in our
foreign currency position would have had an immaterial effect on the results of
our operations, financial position and cash flows.

In fiscal 1999, we derived over 58% of our revenues from sales in foreign
markets. In the six months ended December 31, 1999, we derived approximately 65%
of our revenues from sales in foreign markets. The fair market value of our
foreign currency forward contracts was $43.1 million at December 31, 1999. Our
net realized and unrealized foreign currency gains and losses were less than
$1 million for each of the years ended June 30, 1999, 1998 and 1997 and the six
months ended December 31, 1999.

IMPACT OF THE INTRODUCTION OF THE EURO

On January 1, 1999, eleven member states of the European Union established
fixed conversion rates between their existing national currency and a common
currency, the "euro." Until January 1, 2002, either the euro or the
participating country's present currency will be accepted in non-cash
transactions. On January 1, 2002, euro-denominated bills and coins will be
issued and the participating country's present currency will be gradually
withdrawn during a short period of dual circulation of no more than three
months.

We have initiated an internal analysis to determine the effects of the
January 1, 2002 conversion. The current assessment includes the potential impact
of the technical challenges to adapt information technology and other systems to
accommodate euro-denominated transactions, the impact on currency exchange rate
risk and currency exchange costs, and the impact on existing contracts.

Based on currently available information, we do not believe that the euro
conversion will have a material adverse impact on our business or financial
condition. We will continue to evaluate the impact of the euro conversion.

INCOME TAXES

Our effective tax rate for the six months ended December 31, 1999 was
approximately 27.9%, which differs from the U.S. federal statutory tax rate of
35%, due primarily to higher statutory tax rates in certain foreign
jurisdictions, offset by foreign tax credits, research and development credits,
state tax credits, and a decrease in valuation allowances.

Our effective tax rate in fiscal 1999 was approximately 34.6% due primarily
to the increase in valuation allowance, higher statutory tax rates in certain
foreign jurisdictions and foreign jurisdiction losses without foreign tax
benefit, offset by foreign tax credits, research and development credits and
state tax credits. The difference between the U.S. federal statutory tax rate of
35.0% and our effective tax rate (benefit) of approximately 33.0% and (18.0)% in
fiscal 1998 and 1997, respectively, was attributable mainly to foreign
jurisdiction losses offset by foreign tax credits and state tax credits for 1998
and foreign jurisdiction losses without foreign tax benefits and accruals for
additional tax for 1997.

IMPAIRMENT OF ASSETS, RESTRUCTURING AND SEVERANCE CHARGES

During the fourth quarter of fiscal 1997, due to a decline in selling prices
for our MOSFET and IGBT products, we recorded a $75 million pretax charge
related to a restructuring program designed to improve our cost structure.
Specifically, the restructuring activities included shifting production from
older manufacturing facilities to newer, more efficient facilities, changing
business processes by consolidating order entry, customer support, inventory
management, information systems and finance activities at fewer locations and
accelerating the deployment of our new product development center. The
restructuring activities were expected to reduce the cost of our business
processes and lower product costs and result in increased flow of new products,
which are less price sensitive. The charge was composed of $61 million for the
write-down of assets, $4 million for the write-down of inventory, primarily
wafers, to net realizable value and $10 million for termination benefits to be
paid in connection with the severed employees. The restructuring activities
occurred over an approximate eighteen-month transition period through
December 31, 1998.

We determined the asset write-down of property and equipment of $61 million
by comparing the expected future undiscounted cash flows to the respective asset
carrying value. If an asset was deemed to be impaired, we adjusted the carrying
value to its expected future discounted cash flows. The net book value of the
applicable property and equipment before the $61 million write-down was
$79 million. The write-downs related to the following:

- Wafer fabrication equipment located in El Segundo, California with a
carrying value of $21 million, was adjusted to its fair value of
$2 million. One wafer fabrication line, dedicated primarily to research
and product development, was abandoned and replaced by a new product
development facility in August 1998. The other wafer fabrication line,
which manufactured product using equipment that processed 4-inch wafers,
was abandoned and replaced with a more advanced line located in Italy,
which processes 5-inch wafers, in August 1998. Using 5-inch wafers results
in significant manufacturing savings. The current status of the wafer
fabrication impaired equipment falls into three categories: (1) it was
scrapped as of June 1997, (2) it is idle with no viable plans for usage,
or (3) it is being used on a sporadic basis in research and development.
There is no viable external market for this equipment.

- Assembly equipment in England of $26 million was adjusted to its fair
value of $4 million. Specifically, three product assembly and packaging
lines in England were operating at a gross margin loss. We have continued
to utilize these lines periodically for market development activities, and
these lines remain unprofitable.

- Information systems applications with a carrying value of $32 million were
written down to $12 million as a result of lack of vendor support. Our
software vendor changed business strategies and informed us of its
intention to stop supporting and developing the software technology that
certain of our information systems applications were based upon. In
June 1997, we determined that no viable alternatives could be identified.
Consequently, we ceased development and implementation of certain
forecasting, planning and order management programs and determined the
assets related to these specific activities were impaired (i.e. no future
use and were abandoned). These assets consisted of costs related to
external consulting fees and expenses. The remaining book value relates to
modules that have not been abandoned.

As of June 30, 1999, we had eliminated approximately 242 employees related
to the June 1997 restructuring. The majority of the positions eliminated were
operators and technicians at our North American operations. We also eliminated
production and assembly positions in our manufacturing operations in Italy due
to the outsourcing of certain production and assembly activities. In addition,
we eliminated administrative and sales positions in France, England, Germany,
Japan and North America, related to the regional consolidation of certain
administrative functions.

25
<PAGE>
As of June 30, 1999, there was no remaining accrued severance liability in
our consolidated balance sheet related to the June 1997 restructuring.

We anticipated this restructuring to result in annual savings of
approximately $20 million, which would be fully achieved on an annual basis
beginning in December 1998. We believe that we have achieved these savings, but
they have been more than offset by continued selling price reductions.

During December 1998, we recorded a $14.5 million restructuring charge
associated with plans to relocate high-volume assembly lines from our facility
in England to our facility in Mexico to take advantage of labor rate savings,
and to centralize more of our European customer service and administrative
activities, resulting in reductions in personnel. We expect to complete this
operational transition over the next six months ending on June 30, 2000. The
charge consisted of $5.9 million for estimated severance costs associated with
the elimination of approximately 350 positions, primarily consisting of
operators and technicians, $6.1 million for the write-off of assets to be
abandoned, and $2.5 million for the write-down of inventory related to specialty
product lines. None of the assets written down, which consist primarily of
building improvements relating to the high-volume assembly production lines, and
production information systems, will remain in use and all of them will be
abandoned after the production lines are relocated. In the third quarter of
fiscal 1999, we recorded a final charge of $4.2 million relating to additional
severance costs, after appropriate notification was given to 43 remaining
affected employees in the sales, customer service and administrative areas. The
severance per person is larger for the March 1999 restructuring versus the
December 1998 restructuring as the 43 positions included in the March 1999
restructuring are primarily highly-paid employees in sales and administrative
management. The 350 positions in the December 1998 restructuring are primarily
operators and technicians who have a much lower salary level. Therefore, we
estimate that, ultimately, charges associated with all of these actions will
total approximately $18.7 million.

We expect the anticipated cost savings from the second and third fiscal 1999
quarter restructuring activities to result in estimated annual savings of
approximately $5 million in fiscal 2000 and $13 million annually thereafter.
These estimated savings consist of lower direct labor costs, lower factory
overhead, including lower depreciation expense, lower materials costs and lower
selling and administrative costs.

As of December 31, 1999, we had eliminated 64 positions, paid $6.0 million
for termination benefits related to this program and recorded the asset
impairment of $8.6 million. The remaining unutilized restructuring accrual of
$4.1 million, which is classified as current, relates to severance payments to
these previously notified employees for positions that are scheduled to be
eliminated during the next six months.

During June 1999, we recorded an $8.3 million charge related to employee
severance associated with the elimination of approximately 39 positions. This
included a reduction in sales and administrative management staff levels and the
resignation of Dr. Derek B. Lidow, who shared the responsibility of Chief
Executive Officer. As of December 31, 1999, we had eliminated 25 positions and
paid $4.9 million for termination benefits. The remaining unutilized severance
accrual of $3.4 million at December 31, 1999, which is classified as current,
relates to severance payments to these previously notified employees for
positions that are scheduled to be eliminated during the next six months.

RECENT ACCOUNTING PRONOUNCEMENTS

Effective the first day of fiscal 2000, we adopted SOP 98-1, "Accounting for
the Costs of Computer Software Developed or Obtained for Internal Use." Issued
by the American Institute of Certified Public Accountants ("AICPA"), SOP 98-1
provides standards on accounting for the costs of computer software developed or
obtained for internal use. The new standards do not significantly differ from
our previous accounting treatment for software developed or obtained for
internal use and did not have a significant impact on the Consolidated Financial
Statements.

During fiscal 1999, we elected early adoption of Statement of Position 98-5,
"Reporting on the Costs of Start-Up Activities." This new accounting standard,
issued in April 1998 by the American Institute of Certified Public Accountants,
requires most entities to expense all start-up and preoperating costs as they
are incurred. We previously deferred such costs and amortized them over the life
of the related asset following the start-up of each new process. The early
adoption of SOP 98-5 was required to be made retroactive to the beginning of the
first quarter of fiscal 1999. The cumulative effect of this change in accounting
principle, net of income tax benefit of $5.4 million, was $26.2 million or $0.50
per basic and diluted share and was recorded retroactively to the first quarter
of 1999 as a one-time charge. Beginning July 1, 1998, all start-up and
preoperating costs are expensed as incurred.

Effective July 1, 1998, we adopted Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income," and accordingly have
included a separate Statement of Comprehensive Income following our Consolidated
Statement of Income. Comprehensive income generally represents all changes in
stockholders' equity during the period except those resulting from investments
by, or distributions to, stockholders. The balance of accumulated other
comprehensive income consists of accumulated foreign currency translation
adjustments.

On June 30, 1997, the Financial Accounting Standards Board issued SFAS
No. 131 "Disclosures about Segments of an Enterprise and Related Information."
SFAS No. 131 requires publicly-held companies to report financial and
descriptive information about their operating segments in financial statements
issued to stockholders for interim and annual periods. The Statement also
requires additional disclosures with respect to products and services,
geographic areas of operation and major customers. SFAS No. 131 is effective for
fiscal years beginning after December 15, 1997 and requires restatement of
earlier periods presented. We adopted SFAS No. 131 in the fiscal year ended
June 30, 1999. The adoption of SFAS No. 131 did not affect our results of
operations or financial position, but did affect the disclosure of segment
information as presented in Note 5 of the Notes to Consolidated Financial
Statements.

In February 1998, the FASB issued SFAS No. 132 "Employers' Disclosures about
Pensions and Other Postretirement Benefits." SFAS No. 132 supersedes the
disclosure requirements for SFAS No. 87 "Employers' Accounting for Pensions,"
SFAS No. 88 "Employers' Accounting for Settlements and Curtailments of Defined
Benefit Pension Plans," and SFAS No. 106 "Employers' Accounting for
Postretirement Benefits Other than Pensions." This Statement is effective for
fiscal years beginning after December 15, 1997. This Statement revises
employers' disclosures about pension and postretirement benefit plans. We
adopted SFAS No. 132 in the fiscal year ended June 30, 1999. Our pension
obligation is immaterial and, therefore, not disclosed separately.

In June 1998, the FASB issued SFAS No. 133 "Accounting for Derivative
Instruments and Hedging Activities," which was later amended by SFAS No. 137
"Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133." SFAS No. 133 established standards
for the accounting and reporting for derivative instruments, including certain
derivative instruments embedded in other contracts, and hedging activities. This
Statement generally requires recognition of gains and losses on hedging
instruments, based on changes in fair value or the earnings effect of a
forecasted transaction. SFAS No. 133, as amended by SFAS No. 137, is effective
for all fiscal quarters of fiscal years beginning after June 15, 2000. We do not
believe that SFAS No. 133 or SFAS No. 137 will have a material impact on our
consolidated financial statements.

YEAR 2000 READINESS

The Year 2000 issue is the result of many existing computer programs and
embedded microprocessors using only two digits to refer to the year. Beginning
in the year 2000, these systems need to be upgraded or replaced to distinguish
21(st) century dates from 20(th) century dates.

27
<PAGE>
We have adopted the definition of Year 2000 conformity published by the
British Standards Institute ("BSI") as DISC PD2000-1. Currently, none of our
products contain date processing logic. We, therefore, believe that our products
are Year 2000 compliant pursuant to the BSI DISC PD2000-1 definition.

Our Global Year 2000 Team was formed to manage and coordinate company-wide
Year 2000 initiatives, while local site teams addressed research and remediation
for site-specific equipment, facilities and suppliers. We are estimating
$7.5 million for the cost of investigation and remediation for the period
August 1997 to March 2000. The estimate includes staff salaries and remediation
expenses. Through December 31, 1999, we expensed $6.9 million of this estimate.

We have successfully completed the verification process for all internal
information systems, factory equipment, facilities, suppliers and business
partners. To date, we have not experienced any business interruptions due to any
Year 2000 related cause and have concluded all of our planned investigation and
remediation related to the Year 2000 issue.

Furthermore, we have established programs to ensure that current and future
purchases of equipment and software are Year 2000 compliant pursuant to the BSI
DISC PD2000-1 definition.

Based on currently available information, we do not believe that the Year
2000 matters discussed above will have a material adverse impact on our
financial condition, liquidity, or results of operations. We cannot assure you
that our compliance efforts and contingency plans will adequately address every
issue that may arise in the year 2000. The costs of our Year 2000 remediation
reflect our best estimates, which were based on assumptions of future events,
including the continued availability of certain resources, third-party
compliance and other factors. We cannot assure you that these estimates will be
achieved, and actual results could differ materially from those anticipated.

This disclosure is a Year 2000 statement and constitutes a Year 2000
Readiness Disclosure under Public Law No. 105-271.

BUSINESS

INDUSTRY OVERVIEW

Power semiconductors provide a source of reliable power for a wide range of
electrical and electronic systems and equipment. The more sophisticated the end
product, the greater its need for specially-formatted, finely-regulated power.
The adoption of power semiconductor technology is rising with the increasing
complexity of electronic products and the rapid proliferation of electronic
features in communications, consumer electronics, information technology,
automotive and industrial products. Within the power semiconductor market,
MOSFETs and IGBTs are critical to power management. Based on statistics
published by the Semiconductor Industry Association, industry-wide revenues from
sales of power MOSFETs and IGBTs were $3.13 billion in calendar 1999.

29
<PAGE>
Demand for power semiconductors is being driven by the following:

- GROWTH OF COMMUNICATIONS AND INTERNET INFRASTRUCTURE. Rapid growth in
communications, enterprise computing and the Internet is accelerating
demand for advanced power semiconductors. Internet infrastructure
equipment, such as routers, servers, hubs, and switches rely on
advancements in power management efficiency in order to operate at higher
speeds and to process more information with the desired degree of
reliability.

- INCREASE IN DEMAND FOR PORTABLE ELECTRONICS. Worldwide demand for mobility
and convenience is creating significant growth opportunities in portable
electronics that depend on efficient power conversion to extend battery
life and enhance product performance. The latest-generation personal
computers rely on advances in power management technology to operate
efficiently at ever-lower voltages. In addition, high-efficiency power
semiconductors enable makers of new cellular phones and notebook computers
to offer more compact products that have greater operating speed and
performance.

- INCREASING APPLICATIONS IN AUTOMOTIVE ELECTRONICS AND MOTOR CONTROL. The
proliferation of power features in automobiles and tougher standards for
safety, fuel economy, and emissions are driving the adoption of more
complex power electronics. Electric motors consume approximately half of
the world's electricity. Because of cost and complexity, controls that
permit variable-speed operation have been predominantly used in very
high-end motor applications. Recent advancements in power management make
possible cost-effective, variable-speed motor controls that increase
energy efficiency and improve performance in a wide range of industrial,
commercial, and household applications.

- RECOVERY AND EXPANSION OF ASIA PACIFIC ECONOMIES. The Asia Pacific region
has begun to recover from its recent financial crisis and many Asia
Pacific countries have returned to rapid growth. As disposable income
increases in the region, we expect demand for consumer products, such as
cellular phones, Internet devices, computers, televisions and other
electric appliances, to expand the market for our products.

STRATEGY

We concentrate our resources on opportunities to add value and leverage our
competitive advantages through the following strategic initiatives:

30
<PAGE>
Power Components provides us with a platform for continued expansion in
value-added growth markets.

CAPITALIZE ON LEADING CUSTOMER RELATIONSHIPS. As a result of our leadership
and strength in power semiconductors, industry leaders look to us for products
and programs that address their most challenging power management needs. These
relationships put us at the forefront of developing products for new trends in
the marketplace. We offer high quality customer service with comprehensive sales
and engineering support, including Internet service applications, electronic
order entry and just-in-time delivery. Our leading customers include Alcatel,
American Power Conversion, Compaq, Delphi, IBM, Lockheed-Martin, Lucent, Maxtor,
Mitsubishi, Motorola, Nortel Networks, Philips and Sony. In addition, our rate
of design wins has accelerated into the applications of these customers, as well
as AMD, Bosch, Cisco Systems, Dell, Intel, Qualcomm and Groupe Schneider.

LEVERAGE OUR LEADING TECHNOLOGY POSITION. Our leading technology enables us
to set performance and architecture standards for power electronics in targeted
applications. Our research and development program concentrates on the
advancement of our MOSFET and IGBT technology and the development of Power ICs,
Advanced Circuit Devices and Power Systems that add greater value. Over the past
three years, we have spent approximately $110 million on research and
development. In the first quarter of fiscal 1998, we opened a new research and
development facility that provides submicron process capability and capacity for
rapid development. Our long-term investment in research and development has
resulted in a broad patent portfolio, consisting of 313 issued patents and 430
patents pending. In fiscal 1999, licenses under our patents generated
approximately $26 million in royalties. We believe our technology leadership and
product innovation will continue to be a source of growth in the fastest growing
segments of the power semiconductor industry.

PRODUCTS AND APPLICATIONS

Our products process electrical power into a form that is usable by electric
products. We believe that our full complement of power management technology
represents a competitive advantage, enabling us to provide customers with
integrated solutions for their power management needs. Our products are broadly
divided among three product categories: Power ICs and Advanced Circuit Devices,
Power Systems and Power Components.

POWER ICS AND ADVANCED CIRCUIT DEVICES

A Power IC is a semiconductor that integrates logic and power management
functions on the same chip. These devices optimize the performance of circuits
that often include power MOSFETs and IGBTs and allow our customers to simplify
circuit design and assembly, improve reliability, and reduce overall system size
and cost. The ability of a Power IC to sense and respond to circuit conditions
makes its performance superior to discrete components. Our Power ICs often use
our proprietary power MOSFET technology. We have obtained extensive patent
protection for our Power ICs and have additional patent applications pending.

Advanced Circuit Devices are chipsets, multichip modules and advanced
performance discrete devices that address power management requirements in more
demanding applications.

Increased complexity in routers, servers and high-end enterprise computers
and other devices require increased levels of power and more effective heat
dissipation, making power management one

31
<PAGE>
of the most critical tasks. Notebook computers and other portable devices are
trending to lower voltages and higher current levels, which require greater
efficiency and more complex power management to meet speed and performance
demands and to extend battery life. Over the last two years, we invested heavily
in key trench and planar process technologies. These investments have resulted
in what we believe are the most efficient power MOSFET devices in the
marketplace. We believe this new generation of power MOSFETS sets a new standard
for price/performance in high-volume consumer electronics applications. We have
achieved multiple design wins for our new trench and planar low voltage products
in Power ICs and Advanced Circuit Devices for latest generation digital cell
phones, high-end portable PCs and other products.

POWER SYSTEMS

Power Systems combine power semiconductors with other power management
components in specialized modules that improve power efficiency and simplify
circuit design. We are currently focusing our Power Systems on automotive
electronics and motor control. Our products provide a cost-effective alternative
to custom analog designs.

The proliferation of power features in automobiles and tougher standards for
safety, fuel economy, and emissions are driving the adoption of more complex
power electronics. An engineering group representing Mercedes-Benz, General
Motors, Ford and MIT has forecasted that the electrical load per vehicle could
triple from 800 to 2,400 watts by the year 2005, significantly reducing fuel
efficiency at a time when regulations require improved gas mileage. Our Power
Systems can help offset this impact by replacing traditional hydraulic and
belt-driven applications with electronic systems. For example, electric power
steering systems can increase fuel efficiency by more than one-and-one-half
miles per gallon. In addition, electrically operated automotive systems improve
reliability and maintenance. Power Systems are also designed into automotive
electronics, including integrated starter/alternator motors, fuel and water
pumps and fan controls.

Motors consume approximately half of the world's electricity. New
variable-speed motors equipped with Power Systems increase energy efficiency and
performance in a wide range of industrial, commercial and household
applications. For example, most refrigerator motors can only run at full speed,
but a variable-speed motor can run at the lowest speed needed to maintain the
required refrigerator temperature. Our Power Systems designed for variable-speed
motors reduce electricity consumption, simplify product design, shorten
time-to-market, improve product performance, and reduce overall costs. We have
recently achieved design wins from leading worldwide manufacturers in high-end
refrigerators, washers and home appliances.

COMPONENTS

SWITCHING PRODUCTS. Power MOSFETs and IGBTs rapidly and efficiently switch
electricity on and off in order to break electrical current into elements that
can be formatted to the specific requirements of a circuit. Our
HEXFET-Registered Trademark- power MOSFET and IGBT component products comprised
approximately two-thirds of our fiscal 1999 sales.

Through our HEXFET-Registered Trademark- product line, we believe we are the
market leader in power MOSFETs. Our emphasis on quality control and reliability
has helped us maintain market acceptance and brand recognition of our
HEXFET-Registered Trademark- line of products. We pioneered the fundamental
technology that set the industry standard for power MOSFETs.

MOSFETs are critical in a wide variety of electric products. Communications
applications include cellular phones, telephone networks and modems. Computer
and peripheral applications include power supplies, disk drives and printers.
Office equipment applications include copiers and facsimile machines. Consumer
electronics applications include home entertainment, video cameras, household
appliances, and power tools. Automobile applications include anti-lock braking
systems, fuel injection systems,

32
<PAGE>
power accessories and air bags. Industrial applications include automated
production equipment, instrumentation and test equipment. Government/space
applications include communications satellites and command-and-control systems.

IGBTs typically perform the switch function in industrial applications that
require higher current and voltage than power MOSFETs can handle efficiently.
The performance and ruggedness of these devices enable them to replace bipolar
transistors and thyristors in many high-voltage, high-current motor control and
power conditioning applications. Energy-efficient, variable-speed motor controls
are an emerging application, and we believe electric and hybrid vehicles may
require large quantities of IGBTs for each vehicle. Our IGBT technology is
closely related to our power MOSFET technology. We believe that our patents on
fundamental power MOSFET technology also apply to IGBTs.

RECTIFIERS, DIODES AND THYRISTORS. We manufacture a broad line of
rectifiers, diodes and thyristors. These products, which also condition
electrical power to make it more efficient and usable, are used principally in
industrial end products that require power handling capability from one amp to
5,000 amps and from 20 volts to 5,000 volts. Applications include motor and
lighting controls, welding equipment, fork lifts, machine tools, induction
heating, locomotives, motor-driven production lines, smelting equipment and
power supplies.

Our Schottky diodes and fast-recovery diodes serve the output rectification
function of power conversion. A diode is a discrete device that conducts current
in one direction. A Schottky diode is an ultra-fast diode used in
high-frequency, low-voltage circuits. A fast-recovery diode is a diode suited to
applications above 200 volts where high switching speed is desirable. Schottky
diodes are used with power MOSFETs in high-frequency applications such as
computers and peripherals. Our HEXFRED-Registered Trademark- fast-recovery
diodes are used with IGBTs in higher-current, lower-frequency applications such
as motor controls.

MANUFACTURING

Semiconductor manufacturing involves two phases of production: wafer
fabrication and assembly. Wafer fabrication requires a sequence of process steps
that expose silicon wafers to chemicals that change their electrical properties.
The chemicals are applied in patterns that define cells or circuits within
numerous individual devices, termed "die" or "chips", on each wafer. Assembly is
the sequence of production steps that divide the wafer into individual chips and
enclose the chips in structures, termed "packages", that make them usable in a
circuit. Power semiconductors generally use process technology and equipment
already proven in the manufacturing of integrated circuits.

We have production facilities in California, England, Italy, Mexico, Wales,
India and China. In addition, we have equipment at, or manufacturing supply
agreements with, subcontractors located in the Philippines, Japan, Taiwan,
Malaysia, the Czech Republic, Wales and the United States.

We fabricate the majority of our power MOSFET and IGBT wafers at our HEXFET
America facility in Temecula, California. Our most advanced wafer fabrication
facility, located in El Segundo, California, expands our manufacturing
resources, as well as our development capability. A wafer fabrication facility
for high-voltage Power ICs and other Advanced Circuit Devices, as well as
assembly operations for components used in government/space applications, is
located in El Segundo, California. We manufacture substantially all of our
Schottky diodes, high-power rectifiers and thyristors at our Turin, Italy
facility. Plants that assemble power MOSFETs and other products are located
overseas in facilities we own or in subcontracted facilities. We are in the
process of transferring high-volume assembly lines for power MOSFETs, IGBTs and
diodes from our Oxted, England facility into our existing facility in Mexico. We
have installed a production facility in Penllergaer, Wales, to assemble Power
Systems. We also have arrangements with third parties for product assembly in
the Philippines, Malaysia, Taiwan, Japan, the Czech Republic and Mexico. In a
duty-free zone in India, we have an assembly facility for rectifiers and
thyristors.

MARKETING, SALES AND DISTRIBUTION

We market our products through sales staff, representatives and
distributors. We believe the depth of our power management product line enhances
our competitive position in the overall power semiconductor market.

In fiscal 1999, our product sales by region, based on the location of the
customer, were approximately 42% from North America, 24% from Europe and 34%
from Asia, which includes Japan and Asia Pacific. In the six months ended
December 31, 1999, our product sales in these regions were 41%, 24% and 35%,
respectively. Our domestic direct sales force is organized into four regional
sales zones. In Europe, our products are sold through our own sales force as
well as through independent sales agents and distributors. Our European sales
and representative offices are in England, Italy, Sweden, France, Germany,
Finland, Denmark, Switzerland, Russia, the Czech Republic and Hungary. In Asia,
we have sales, representative or liaison offices in India, Japan, Singapore,
China, Hong Kong, South Korea, Taiwan, the Philippines, Australia and New
Zealand.

Because many applications require products from several product groups, we
have organized our marketing efforts by application, rather than product type.
These groups focus on several key commercial sectors and on government/space
business. In addition, our staff of application engineers provides customers
with technical advice and support regarding the use of our products.

CUSTOMERS

Our devices are incorporated in subsystems and end-products manufactured by
other companies. Approximately 40% of our revenues comes from sales of our
products to distributors. We have historically found it more difficult to
determine distributor demand than demand from our other customers. Sales to one
customer, Arrow Electronics, accounted for 10.7% of our revenues in fiscal 1999.
The following table lists our major customers by end-market for fiscal 1999:

BACKLOG

As of December 31, 1999, our backlog of orders was $166.6 million compared
to $146.9 million as of June 30, 1999. Backlog is comprised of purchase orders
and customer forecast commitments scheduled to be shipped within the following
twelve months. Increasingly, major customers are operating their businesses with
shorter lead-times and are placing their orders at shorter intervals,

34
<PAGE>
which tends to reduce backlog relative to future revenue. Given adequate notice,
we usually allow customers to cancel purchase orders without penalty. Backlog is
not necessarily indicative of sales for any future period.

RESEARCH AND DEVELOPMENT

We conduct research and development activities to improve the
price/performance ratio of our product offerings across a wide range of end-use
applications. Our research and development program focuses on Power ICs,
Advanced Circuit Devices and Power Systems and the advancement and
diversification of our HEXFET-Registered Trademark- power MOSFET and IGBT
product lines. We also direct our research and development towards reducing the
cost of customers' existing products and products in development. Our program
places increasing emphasis on the development of chipsets and system-level
solutions that improve overall system performance and cost and help customers to
accelerate market introduction of their products.

In the six months ended December 31, 1999, and the fiscal years 1999 and
1998, we spent approximately $21.7 million, $40.5 million and $39.1 million,
respectively, on research and development activities.

Our research and development center in El Segundo provides increased
capacity and submicron capability for development, pilot production and limited
production of advanced power MOSFETs and IGBTs. The 55,000 square foot facility
incorporates a 12,000 square-foot clean-room and is designed to support greater
levels of development activity.

During the first six months of fiscal 2000, our product introductions
accelerated, and we achieved cost reductions and performance enhancements across
the full range of our product line. Our new benchmark products for target
applications introduced in fiscal 1999 and the first six months of fiscal 2000
included:

- Multiple design wins for new trench and planar low-voltage MOSFETs that
increase our penetration in advanced digital cell phones and high-end
portable PCs;

- New high-voltage power MOSFETs that combine process technologies to
achieve benchmark performance in power supplies for servers and routers
needed to carry internet traffic;

- High-performance intelligent power switches, proprietary Power ICs and
proprietary modules that won designs in electric power steering, fan
controls and diesel fuel injection applications;

- Proprietary high-voltage Power ICs and IGBTs that have been designed into
high-end refrigerators and washing machines by major U.S., European and
Asian brand-name OEM's;

- Power ICs for dimmable electronic lighting; and

- A new chipset, built around a unique 1200 Power IC, which adds
functionality and sharply increases our product content in industrial
motor drives.

INTELLECTUAL PROPERTY

We have made significant investments in developing and protecting our
intellectual property. Through successful enforcement of our patents, we have
entered into a number of license agreements, generated royalty income, and
received substantial payments in settlement of litigation. We currently have 155
unexpired U.S. patents and 132 U.S. patents pending. Our power MOSFET patents
expire between 2000 and 2010, with the broadest remaining in effect until 2007
and 2008. In addition, we have 158 issued foreign patents and 298 foreign
patents pending in a number of countries. We are also licensed to use certain
patents owned by others. We have several registered trademarks in the United
States and abroad, including the trademark HEXFET-Registered Trademark-. We
believe that our proprietary technology and intellectual property contribute to
our competitive advantage.

35
<PAGE>
We are committed to enforcing our rights under our patents, including
through litigation, if necessary. In January 1999, we announced agreements that
settled outstanding patent litigation with Samsung Semiconductor, Inc. and
Samsung Electronics Company and with Fuji Electric Company and Collmer
Semiconductor, Inc. In the second half of fiscal 1999, we settled litigation and
disputes with Shindengen Electric Company and Rohm Co., Ltd., respectively,
which resulted in two additional royalty-bearing license agreements. We
currently have license agreements with most of the major power MOSFET
manufacturers in the United States and abroad. In fiscal 1999, we derived
$26.5 million of net revenues from license agreements and in the six months
ended December 31, 1999, we derived $15.1 million of net revenues from license
agreements. Other income of $53.5 million in fiscal 1999 primarily consisted of
proceeds from license agreements for prior periods and amounts in settlement of
litigation for past patent infringement, net of legal costs and the share of our
royalty proceeds payable to Unitrode Corporation. Under the terms of an
agreement with Unitrode Corporation, we pay Unitrode approximately 12% of our
net patent royalty income from our power MOSFET patents. We do not believe that
the expiration of four of our power MOSFET patents in 2000 will have a material
adverse effect on our licensing revenues. Most of our broadest power MOSFET
patents were subject to, and have successfully emerged from, reexamination by
the United States Patent and Trademark Office.

COMPETITION

We encounter differing degrees of competition for our various products,
depending upon the nature of the product and the particular market served.
Generally, the semiconductor industry is highly competitive and subject to rapid
price changes, and many of our competitors are larger companies with greater
financial resources. We believe that we are distinguished from our competitors
by our comprehensive line of power management products and ability to combine
these products into compact, cost-effective packages and system-level solutions.
Our products compete with products manufactured by others on the basis of
breadth of product line, quality, price, reliability, overall performance of the
products, delivery time to the customer, and service (including technical advice
and support). Our major competitors include: Fairchild Semiconductor
Corporation, Infineon Technologies AG (formerly Siemens AG), Intersil
Corporation (formerly part of Harris Corporation), NEC Corporation, On
Semiconductor (formerly a division of Motorola, Inc.), Philips International
B.V., ST Microelectronics (formerly called SGS-Thomson Microelectronics),
Toshiba Corporation, and Vishay-Siliconix Incorporated.

ENVIRONMENTAL MATTERS

Federal, state, and local laws and regulations impose various restrictions
and controls on the storage, use and discharge of certain materials, chemicals,
and gases used in semiconductor manufacturing processes. We do not believe that
compliance with such laws and regulations as now in effect will have a material
adverse effect on our results of operations, financial position or cash flows.

However, under some of these laws and regulations, we could be held
financially responsible for remedial measures if properties are contaminated, or
if waste is sent to a landfill or recycling facility that becomes contaminated.
Also, we may be subject to common law claims if we release substances that
damage or harm third parties. We cannot make assurances that changes in
environmental laws and regulations will not require additional investments in
capital equipment and the implementation of additional compliance programs in
the future which could have a material adverse effect on our results of
operations, financial position or cash flows, as could any failure by us to
comply with environmental laws and regulations.

superfund site in Monterey Park, California, known as the OII Site. Other
potentially responsible parties who settled certain claims with the EPA under
consent decrees filed suit in Federal Court in May 1992 against a number of
other such parties, including us, for cost recovery and contribution under the
provisions of the Comprehensive Environmental Response, Compensation and
Liability Act. We have settled all outstanding claims that have arisen out of
this site. No claims against Rachelle have been settled.

We also received a letter dated July 25, 1995 from the U.S. Department of
Justice, directed to Rachelle, offering to settle claims against Rachelle
relating to the first elements of clean-up work at the site for $4,953,148, but
the final remedy assessment has not yet been made. The offer stated that the
settlement would not cover the cost of any additional remedial actions required
to finish the clean-up. This settlement offer expired by its terms on
September 1, 1995. On August 7, 1995, we received a Supplemental Information
Request from the EPA directed to Rachelle, to which counsel for Rachelle
responded with information regarding waste shipped to the site. Counsel for
Rachelle received a letter from the EPA dated September 30, 1997, requesting
that Rachelle participate in the final remedial actions at the site, and counsel
replied on October 21, 1997. We have taken the position that none of the wastes
generated by Rachelle were hazardous. We have received no further communications
in connection with this site.

We cannot determine with accuracy the amount of the potential demand to
Rachelle for the cost of the final remedy. Based upon information received to
date, we believe that any demand for the cost of the final remedy, if made,
would likely be significant, although it should be substantially below, the
demand amount for earlier phases of the site clean-up. Any demands related to
the cost for the final remedy would be in addition to the amount demanded for
earlier phases of the OII Site clean-up. Our insurer has not accepted liability
although it has made payments for defense costs we have incurred in connection
with the lawsuit.

We also received a letter dated September 9, 1994, from the State of
California Department of Toxic Substances Control stating that we may be a
potentially responsible party for the deposit of hazardous substances at a
facility in Whittier, California. In June 1995, we joined a group of other
potentially responsible parties to remove contamination from the site. The group
currently estimates the total cost of the clean-up to be between $20 million and
$25 million, although the actual cost could be much higher. We estimated that we
sent approximately 0.1% of the waste, by weight, sent by all parties
contributing to the clean-up of the site, and we believe the cost of the
clean-up will be roughly allocated among the parties by the amount of waste
contributed. On July 31, 1999, the group proposed two settlement offers: one for
$34,165 and the second for $68,330. The first settlement offer covers
investigation and remediation of the site itself and a small area extending
beyond the site. The second settlement offer covers this area plus all
additional downgradient contamination. On September 14, 1999, we accepted the
$68,330 settlement offer, which requires EPA acceptance, and made the required
payment on September 28, 1999. There can be no assurance, however, that the EPA
will accept the settlement offers or what the ultimate outcome of this matter
will be. We believe that, whatever the outcome, it will not have a material
adverse effect on our financial condition, results of operations or cash flows.

EMPLOYEES

As of December 31, 1999, we employed approximately 4,588 people, of whom
approximately 3,434 were employed in North America, 1,017 in Western Europe and
137 in Asia. The only collective bargaining agreements to which we are subject
are with respect to our employees in Italy. We have approximately 500 employees
in Italy. We consider our relations with our employees to be good.

The Wales Development Agency agreed to build a 80,000 square foot
manufacturing facility for us. The building is scheduled to be completed in
March 2000. Upon completion, we will purchase the building for approximately
$4 million.

We believe our facilities are adequate for our current and anticipated
near-term operating needs. We estimate that we currently utilize approximately
73% of our worldwide manufacturing capacity.

We have sales or technical support offices located throughout the United
States and in Canada, France, Denmark, Germany, Switzerland, Finland,
Scandinavia, Russia, the Czech Republic, Hungary, Hong Kong, Japan, China,
Korea, Taiwan, the Philippines, Singapore and India, which operate in leased
facilities.

LEGAL PROCEEDINGS

We and some of our directors and officers have been named as defendants in
three class action lawsuits filed in Federal District Court for the Central
District of California in 1991. These suits seek unspecified but substantial
compensatory and punitive damages for alleged intentional and negligent
misrepresentations and violations of the federal securities laws in connection
with the public offering of our common stock completed in April 1991 and the
redemption and conversion in June 1991 of our 9% Convertible Subordinated
Debentures due 2010. They also allege that our projections for growth in fiscal
1992 were materially misleading. Two of these suits also named our underwriters,
Kidder, Peabody & Co. Incorporated and Montgomery Securities, as defendants.

The Court has granted summary judgment in favor of our underwriters and has
dismissed the claims brought under Section 11 and 12(2) of the Securities Act of
1933 and the claims based on common law fraud and negligent misrepresentation in
the prospectuses. Accordingly, the remaining claims are under Section 10(b) of
the Securities Exchange Act of 1934 and Rule 10b-5 thereunder.

The Court decertified the class pursuing common law claims for fraud and
negligent misrepresentation and granted the defendants' motion to narrow the
stockholder class period to June 19, 1991 through October 21, 1991. The trial is
currently scheduled for March 14, 2000.

Although we believe that the remaining claims alleged in the suits are
without merit, we cannot presently determine the ultimate outcome. A substantial
judgment or settlement, if any, could have a material adverse effect on our
results of operations, financial position or cash flows. No provision for any
liability that may result upon adjudication of these matters has been made in
the Consolidated Financial Statements.

DESCRIPTION OF CAPITAL STOCK

The following description summarizes the most important terms of our capital
stock. Because it is only a summary, it does not contain all of the information
that may be important to you. For a complete description, you should refer to
our Restated Certificate of Incorporation, or Certificate of Incorporation, and
Amended and Restated Bylaws, or Bylaws.

Our Certificate of Incorporation authorizes us to issue 150 million shares
of common stock and 1 million shares of preferred stock. No other classes of
capital stock are authorized under our Certificate of Incorporation.

COMMON STOCK

Each share of common stock is entitled to one vote on all matters submitted
to a vote of the stockholders. Holders of common stock may receive dividends
only when our Board of Directors declares them, but our secured credit agreement
prohibits us from paying dividends without obtaining prior approval. In certain
cases, common stockholders may not receive dividends until we have satisfied our
obligations to any preferred stockholders. If we liquidate, dissolve or wind-up
our business, either voluntarily or not, common stockholders will share equally
in the assets remaining after we pay our creditors and any preferred
stockholders. The common stock has no preemptive, conversion or other
subscription rights, and all outstanding shares are fully paid and
non-assessable.

PREFERRED STOCK

Our board of directors may issue shares of preferred stock at any time, in
one or more series, without stockholder approval. The board of directors will
determine the designation, relative rights, preferences and limitations of each
series of preferred stock. If we issue preferred stock, it could delay a change
in control and make it harder to remove our present management. Under certain
circumstances, preferred stock could also adversely affect the voting power of
common stockholders.

RIGHTS AGREEMENT

In August 1996, our board of directors declared a distribution of one right
for each outstanding share of common stock. The distribution was made as of
August 14, 1996, to the stockholders of record on that date. Each right entitles
the registered holder to purchase from us, initially, one one-thousandth of a
share of junior participating preferred stock at a purchase price of $135.00,
subject to adjustment. The description and terms of the rights are set forth in
a rights agreement between Chase Mellon Shareholder Services as rights agent and
us. You should refer to the rights agreement for a more detailed description of
the terms and provisions of the rights. You may obtain a copy of the rights
agreement from us free of charge by contacting our transfer agent. See "Where
You Can Find More Information." Any certificates representing shares of common
stock we issue in this offering will contain a notation incorporating the rights
agreement by reference.

POSSIBLE ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS

In addition to the authorized preferred stock, other provisions of our
Certificate of Incorporation and Bylaws may make it more difficult for a third
party to acquire, or may discourage a third party from attempting to acquire
control of us.

In accordance with provisions contained in our Certificate of Incorporation
and Bylaws, our board of directors is divided into three classes with staggered
three year terms for each class. The Certificate of Incorporation and Bylaws
provide that the directors have the right to increase (with certain
restrictions) or decrease the number of directors. The Certificate of
Incorporation provides that

42
<PAGE>
vacancies for newly created directorships may be filled by a majority vote of
the remaining directors and removal for cause may only be made by the vote of a
majority of the outstanding shares.

Amendment of any of the foregoing provisions of our Certificate of
Incorporation requires the approval of the holders of at least 66 2/3% of our
stock issued and outstanding having voting power, given at a duly convened
stockholders meeting upon a proposal adopted by our board.

Under our Bylaws, a special meeting of stockholders may be called only by
certain officers or a majority of the board.

CERTAIN PROVISIONS OF DELAWARE LAW

We are a Delaware corporation and are subject to Section 203 of the Delaware
General Corporation Law, or DGCL. In general, Section 203 prevents an
"interested stockholder" (defined generally as a person owning 15% or more of a
corporation's outstanding voting stock) from engaging in a "business
combination" (as defined therein) with a Delaware corporation for three years
following the date of the transaction in which the person became an interested
stockholder, unless

(a) before the date of the proposed action, the board of directors of the
corporation approved either the business combination or the transaction
in which the stockholder became an interested stockholder;

(b) upon consummation of the transaction that resulted in the stockholder
becoming an interested stockholder, the interested stockholder owned at
least 85% of the voting stock of the corporation outstanding at the time
the transaction commenced (excluding shares owned by persons who are both
officers and directors of the corporation and shares held by certain
employee stock plans); or

(c) on or after the date of the proposed action, the business combination is
approved by the board of directors of the corporation and authorized at a
meeting of stockholders, and not by written consent, by the affirmative
vote of the holders of at least two-thirds of the outstanding voting
stock of the corporation not owned by the interested stockholder.

LIMITATION OF LIABILITY AND INDEMNIFICATION AGREEMENTS

Our Certificate of Incorporation provides that to the fullest extent
permitted by the DGCL, our directors will not be liable to us or our
stockholders for monetary damages for breach of fiduciary duty as a director.
Under the DGCL, liability of a director may not be limited

(a) for any breach of the director's duty of loyalty to us or our
stockholders,

(b) for acts or omissions not in good faith or involving intentional
misconduct or a knowing violation of law,

(d) for any transaction from which the director derives an improper personal
benefit.

The effect of the provisions of our Certificate of Incorporation is to
eliminate our rights and the rights of our stockholders (through stockholders'
derivative suits on our behalf) to recover monetary damages against a director
for breach of the fiduciary duty of care as a director (including breaches
resulting from negligent or grossly negligent behavior), except in the
situations described in clauses (a) through (d) above. This provision does not
limit or eliminate our rights or the rights of any stockholder to seek
nonmonetary relief, such as an injunction or rescission, in the event of a
breach of a director's duty of care. In addition, our Certificate of
Incorporation provides that we will indemnify our directors, officers, employees
and agents against losses incurred by any such person because such person was
acting in such capacity.

Subject to the terms and conditions stated in the underwriting agreement
dated the date hereof, each underwriter named below has severally agreed to

such underwriter.

The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in this offering are subject to
approval of certain legal matters by counsel and to certain other conditions.
The underwriters are obligated to purchase all the shares (other than those
covered by the over-allotment option described below) if they purchase any of
the shares.

Salomon Smith Barney Inc. is acting as book-running lead manager for this
offering. Salomon Smith Barney Inc. and J.P. Morgan & Co. are acting as
joint-lead managers. The underwriters propose to offer some of the shares
directly to the public at the public offering price set forth on the cover page
of this prospectus and some of the shares to certain dealers at the public
offering price less a concession not in excess of $ per share. The
underwriters may allow, and such dealers may reallow, a concession not in excess
of $ per share on sales to certain other dealers. If all of the shares
are not sold at the offering price, the underwriters may change the public
offering price and the other selling terms.

International Rectifier has granted to the underwriters an option,
exercisable for 30 days from the date of this prospectus, to purchase up to
1,200,000 additional shares of common stock at the public offering price less
the underwriting discount. The underwriters may exercise such option solely for
the purpose of covering over-allotments, if any, in connection with this
offering. To the extent such option is exercised, each underwriter will be
obligated, subject to certain conditions, to purchase a number of additional
shares approximately proportionate to such underwriter's initial purchase
commitment.

International Rectifier and its executive officers and directors have agreed
that, for a period of 90 days from the date of this prospectus, they will not,
without the prior written consent of Salomon Smith Barney Inc., dispose of or
hedge any shares of common stock of International Rectifier or any securities
convertible into or exchangeable for common stock. Salomon Smith Barney Inc. in
its sole discretion may release any of the securities subject to these lock-up
agreements at any time without notice. The common stock is listed on The New
York Stock Exchange and the Pacific Exchange under the symbol "IRF".

The following table shows the underwriting discounts and commissions to be
paid to the underwriters by International Rectifier and the selling stockholder
in connection with this offering.

In connection with the offering, Salomon Smith Barney Inc., on behalf of the
underwriters, may purchase and sell shares of common stock in the open market.
These transactions may include over-allotment, syndicate covering transactions
and stabilizing transactions. Over-allotment involves syndicate sales of common
stock in excess of the number of shares to be purchased by the underwriters in
the offering, which creates a syndicate short position. Syndicate covering
transactions involve purchases of the common stock in the open market after the
distribution has been completed in order to cover syndicate short positions.
Stabilizing transactions consist of certain bids or purchases of common stock
made for the purpose of preventing or retarding a decline in the market price of
the common stock while the offering is in progress.

The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney Inc., in covering syndicate short positions or making
stabilizing purchases, repurchases shares originally sold by that syndicate
member.

Any of these activities may cause the price of the common stock to be higher
than the price that otherwise would exist in the open market in the absence of
such transactions. These transactions may be effected on The New York Stock
Exchange, the Pacific Exchange or in the over-the-counter market, or otherwise
and, if commenced, may be discontinued at any time.

International Rectifier will pay the expense of this offering, estimated to
be $800,000.

International Rectifier and the selling stockholder have agreed to indemnify
the underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, or to contribute to payments the underwriters may be
required to make in respect of any of those liabilities.

LEGAL MATTERS

O'Melveny & Myers LLP, Los Angeles, California, will pass upon the validity
of the shares of common stock we are offering. Latham & Watkins, Los Angeles,
California will pass upon certain legal matters for the underwriters.

REPORT OF INDEPENDENT ACCOUNTANTS

The Stockholders and Board of Directors

International Rectifier Corporation

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, comprehensive income, stockholders'
equity, and cash flows present fairly, in all material respects, the financial
position of International Rectifier Corporation and its subsidiaries at
June 30, 1999 and 1998, and the results of their operations and their cash flows
for each of the three years in the period ended June 30, 1999, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Company's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

As discussed in Note 1 to the consolidated financial statements, in fiscal
1999 the Company changed its method of accounting for the cost of start-up
activities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

ALL INFORMATION SUBSEQUENT TO JUNE 30, 1999 AND FOR THE

SIX MONTHS ENDED DECEMBER 31, 1998 AND 1999 IS UNAUDITED

1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS

International Rectifier Corporation ("Company") is a leading designer,
manufacturer and marketer of power semiconductors and the leading worldwide
supplier of a type of power semiconductor called a MOSFET, a metal oxide
semiconductor field effect transistor. Power semiconductors perform a power
management function by converting electricity into a form more usable by
electrical products. The technology advancements of power semiconductors
increase system efficiency, allow more compact end products, improve features
and functionality and extend battery life. The Company's products are used in a
range of end markets, including communications, consumer electronics,
information technology, automotive, industrial and government/space.

IR was founded as a California corporation in 1947 and reincorporated in
Delaware in 1979.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company
and all of its majority-owned subsidiaries that are located in Europe, Mexico,
Japan and Southeast Asia. All material intercompany transactions have been
eliminated.

UNAUDITED INFORMATION

The consolidated financial statements and related disclosures for the
six-month periods ended December 31, 1998 and 1999 included herein are
unaudited; however, they contain all normal recurring adjustments which, in the
opinion of management, are necessary to present fairly the consolidated
financial position of the Company at December 31, 1999 and the consolidated
results of operations and cash flows for the six-month periods ended
December 31, 1998 and 1999. It should be understood that accounting measurements
at interim dates inherently involve greater reliance on estimates than at
year-end. The results of operations for the six-month period ended December 31,
1999 are not necessarily indicative of the results to be expected for the full
year.

FISCAL PERIODS

The Company operates on a fiscal calendar under which fiscal 1997 consisted
of 52 weeks ending June 29. Fiscal 1998 consisted of 53 weeks ending July 5 and
fiscal 1999 consisted of 52 weeks ending July 4. For convenience, all references
herein to fiscal years are to fiscal years ended June 30. The six months ended
December 31, 1998 and 1999 each consisted of 26 weeks.

REVENUE RECOGNITION

The Company recognizes revenues from product sales to all customers,
including distributors, at the time of shipment.

RESEARCH AND DEVELOPMENT

Research and development costs are expensed as incurred.

1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

ADVERTISING

The Company expenses all advertising costs in the periods in which those
costs are incurred. The Company shares portions of certain distributors'
advertising expenses through cooperative advertising arrangements. In fiscal
1997, 1998 and 1999, the Company spent approximately $4,078,000, $3,579,000 and
$3,928,000, respectively, on advertising. In the six months ended December 31,
1998 and 1999, the Company spent approximately $1,886,000 and $1,761,000,
respectively, on advertising.

ENVIRONMENTAL COSTS

Costs incurred to investigate and remediate contaminated sites are expensed.

INCOME TAXES

Deferred income taxes are determined based on the difference between the
financial reporting and tax bases of assets and liabilities using enacted rates
in effect during the year in which the differences are expected to reverse.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amount expected to be realized. Income tax expense is the tax
payable for the period and the change during the period in deferred tax assets
and liabilities.

At June 30, 1999, U.S. income taxes have not been provided on approximately
$24,550,000 of undistributed earnings of foreign subsidiaries since management
considers these earnings to be invested indefinitely or substantially offset by
foreign tax credits. It is not practicable to estimate the amount of
unrecognized deferred U.S. taxes on these undistributed earnings.

NET INCOME (LOSS) PER COMMON SHARE

Net income (loss) per common share-Basic is computed by dividing net income
(loss) available to common stockholders (the numerator) by the weighted average
number of common shares outstanding (the denominator) during the period. The
computation of Net income (loss) per common share-Diluted is similar to the
computation of Net income (loss) per common share-Basic except that the
denominator is increased to include the number of additional common shares that
would have been outstanding if the dilutive potential common shares had been
issued.

STATEMENT OF CASH FLOWS

The Company invests excess cash from operations in investment grade money
market instruments. The Company considers all highly liquid debt instruments
with a purchased maturity of three months or less to be cash equivalents.

SHORT-TERM INVESTMENTS

The Company's short-term investments consist of investment grade money

less than one year. In accordance with the criteria established by Statement of
Financial Accounting Standards ("SFAS") No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," all investments have been classified
as "available-for-sale." The Company utilizes the specific identification method
for determining the cost of the investments. At June 30, 1998 and 1999, the cost
of the investments approximates the market value.

Repairs and maintenance costs are charged to expense. In the fiscal years
ended June 30, 1997, 1998 and 1999, repairs and maintenance costs were
$16,016,000, $18,757,000 and $16,686,000, respectively. In the six months ended
December 31, 1998 and 1999, repairs and maintenance costs were $7,708,000 and
$10,480,000, respectively.

Historically, preoperating and start-up costs incurred in connection with
construction of major new production facilities were capitalized until such
facilities became operational. These costs were then amortized over the lives of
such facilities. Effective fiscal 1999, preoperating and start-up costs are
expensed as incurred in accordance with Statement of Position ("SOP") 98-5, as
described more fully below in the Recent Accounting Pronouncements section of
Note 1 to the Consolidated Financial Statements.

LONG-LIVED ASSETS

The Company identifies and records impairment losses on long-lived assets
when events and circumstances indicate that such assets might be impaired. The
Company periodically evaluates the recoverability of its long-lived assets based
on expected undiscounted cash flows and recognizes impairments, if any, based on
expected discounted cash flows.

INTANGIBLE ASSETS

Patent and related costs are amortized using the straight-line method over
the life of the related patent portfolio.

CONCENTRATION OF RISK

The Company places its temporary cash investments with high credit quality
financial institutions. At times, such investments may be in excess of insured
limits.

The Company performs periodic credit evaluations of its customers' financial
condition and generally does not require collateral. Receivables on average are
due in 60 days. Credit losses have consistently been within management's
expectations.

FINANCIAL CURRENCY TRANSACTIONS

In general, the functional currency of a foreign operation is deemed to be
the local country's currency. Assets and liabilities of operations outside the
United States are translated into U.S. dollars using current exchange rates.
Income and expense are translated at average exchange rates prevailing during
the period. The effects of foreign currency translation adjustments are included
as a component of stockholders' equity. At June 30, 1998 and 1999, accumulated
foreign currency translation losses were $5,542,000 and $6,121,000,
respectively. At December 31, 1999, accumulated foreign currency translation
loss was $5,082,000.

The Company hedges certain portions of its exposure to foreign currency
fluctuations of foreign currency denominated receivables and payables at certain
of its international subsidiaries through forward foreign exchange contracts. At
June 30, 1998 and 1999, the Company had approximately $26,100,000 and
$44,581,000, respectively, of forward foreign exchange contracts outstanding
with fair values of $25,916,000 and $43,922,000, respectively. At December 31,
1999, the Company had approximately $43,566,000 of forward foreign exchange
contracts outstanding, with a fair value of $43,083,000. The fair value of
foreign currency contracts is estimated based on the spot rate of the various
hedged currencies as of the end of the period. Total net realized and unrealized
gains or losses on forward contracts for the years ending June 30, 1998 and 1999
were $89,000 and $287,000, respectively. For the six months ended December 31,
1999, total net realized and unrealized losses on forward contracts were
$568,000. These net realized and unrealized gains or losses were included in
"Other Income (Expense)." The Company does not hold or issue forward contracts
for trading purposes.

At June 30, 1998 and 1999, maturities of the Company's forward foreign
exchange contracts were three months or less in term.

INTEREST RATE SWAPS

Under the Company's new Credit Agreement entered into on June 30, 1999, the
Company is required to hedge the interest rate for at least half of the
$152.1 million in outstanding term loans under the agreement. The Company has
entered into interest rate swap agreements to hedge 50% of these outstanding
term loans. The purpose of these swaps is to offset with a fixed interest rate a
portion of the risk inherent in this variable-rate debt. Under these agreements,
IR will pay the counterparties (the parties assuming the interest rate risk)
interest at a weighted average fixed rate of 6.2% and the counterparties will
pay IR interest at a variable rate equal to LIBOR. The weighted average
three-month LIBOR rate applicable to these agreements was 6.2% at December 31,
1999.

ESTIMATES

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

STOCK-BASED COMPENSATION

The Company accounts for its stock-based compensation plans using the
intrinsic value method prescribed in Accounting Principles Board ("APB") Opinion
No. 25, "Accounting for Stock Issued to Employees." SFAS No. 123, "Accounting
for Stock-Based Compensation," encourages, but does not require companies to
record stock-based employee compensation plans at fair value. The Company has
elected to continue accounting for stock-based compensation in accordance with
APB No. 25 and is providing the required disclosures under SFAS No. 123 in the
Notes to the Consolidated Financial Statements.

RECENT ACCOUNTING PRONOUNCEMENTS

Effective the first day of fiscal 2000, the Company adopted SOP 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use." SOP 98-1 provides guidance on accounting for the costs of
computer software developed or obtained for internal use. The new guidance does
not significantly differ from the Company's previous accounting treatment for
software developed or obtained for internal use, and as a result, did not have a
significant impact on the Consolidated Financial Statements.

The Company elected early adoption of SOP 98-5, "Reporting on the Costs of
Start-Up Activities," during fiscal 1999. This new accounting standard, issued
in April 1998 by the American Institute of Certified Public Accountants,
requires most entities to expense all start-up and preoperating costs as they
are incurred. The Company previously deferred such costs and amortized them over
the life of the related asset following the start-up of each new process. The
early adoption of SOP 98-5 was required to be made retroactive to the beginning
of the Company's first quarter of fiscal 1999. The cumulative effect of this
change in accounting principle, net of income tax benefit of $5.4 million, was
$26.2 million, $0.50 per basic and diluted share, and was recorded retroactively
to the first quarter of fiscal 1999 as a one-time charge. Effective July 1,
1998, all start-up and preoperating costs are expensed as incurred.

Effective July 1, 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income," and accordingly has included a separate Consolidated
Statement of Comprehensive Income following the Company's Consolidated Statement
of Income. Comprehensive income generally represents all changes in
stockholders' equity during the period except those resulting from investments
by, or distributions to, stockholders. The balance of accumulated other
comprehensive income consists of accumulated foreign currency translation
adjustments.

On June 30, 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 131 "Disclosures about Segments of an Enterprise and Related
Information". SFAS No. 131 requires publicly-held companies to report financial
and descriptive information about their operating segments in financial
statements issued to stockholders for interim and annual periods. The Statement
also requires additional disclosures with respect to products and services,
geographic areas of operation, and major customers. SFAS No. 131 is effective
for fiscal years beginning after December 15, 1997 and requires restatement of
earlier periods presented. The Company adopted SFAS No. 131 in the fiscal year
ended June 30, 1999. The adoption of SFAS No. 131 did not affect the Company's
results of

operations or financial position, but did affect the disclosure of segment
information as presented in Note 5 of the Notes to the Consolidated Financial
Statements.

In February 1998, the FASB issued SFAS No. 132 "Employers' Disclosures about
Pensions and Other Postretirement Benefits." SFAS No. 132 supersedes the
disclosure requirements for SFAS No. 87 "Employers' Accounting for Pensions,"
SFAS No. 88 "Employers' Accounting for Settlements and Curtailments of Defined
Benefit Pension Plans," and SFAS No. 106 "Employers' Accounting for
Postretirement Benefits Other than Pensions." This Statement is effective for
fiscal years beginning after December 15, 1997. This Statement revises
employers' disclosures about pension and postretirement benefit plans. The
Company adopted SFAS No. 132 in the fiscal year ended June 30, 1999. The
Company's pension obligation is immaterial and, therefore, not disclosed
separately.

In June 1998, the FASB issued SFAS No. 133 "Accounting for Derivative
Instruments and Hedging Activities," which was later amended by SFAS No. 137
"Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133." SFAS No. 133 established standards
for the accounting and reporting for derivative instruments, including certain
derivative instruments embedded in other contracts, and hedging activities. This
Statement generally requires recognition of gains and losses on hedging
instruments, based on changes in fair value or the earnings effect of a
forecasted transaction. SFAS No. 133, as amended by SFAS No. 137, is effective
for all fiscal quarters of fiscal years beginning after June 15, 2000.
Management does not believe that SFAS No. 133 or SFAS No. 137 will have a
material impact on the Consolidated Financial Statements.

RECLASSIFICATION

Certain reclassifications have been made to previously reported amounts to
conform to the current-period presentation.

2. BANK LOANS AND LONG-TERM DEBT

At June 30, 1999, the Company entered into a syndicated Credit Agreement
with Banque Nationale de Paris as Sole Arranger, Administrative Agent and
Issuing Agent and Sanwa Bank California as the Syndication Agent. The financing
consisted of two term loans totaling $155 million due in 2004 and 2005 and a
$70 million revolving credit facility. The proceeds from the term loans were
used to pay down all of the Company's existing long-term unsecured bank loans
and substantially all domestic loans. The interest rate on these two term loans
is based on 3.0% and 3.5% above the applicable LIBOR rate and 2.0% to 2.5% above
the applicable base rate. The base rate applies to borrowings which are shorter
than 30 days. The interest rate on the revolving credit facility is based on
either 3.0% above the applicable LIBOR rate or 2.0% above the prime rate as the
Company may elect. At June 30, 1999, outstanding borrowings on the term loans
were $155 million with a weighted average interest rate of 8.79% and the
revolving credit facility had $70 million available for borrowing. At
December 31, 1999, $152.1 million was outstanding against these two term loans,
and no borrowings had occurred against the $70 million revolving line of credit.
The loans are collateralized by the majority of the Company's assets. The Credit
Agreement imposes some restrictions, including the following: (a) maximum
leverage, minimum interest coverage and fixed charge coverage ratios

(b) minimum EBITDA (Earnings Before Interest, Taxes, Depreciation and
Amortization) (c) maximum capital expenditures and (d) a limitation on losses.
The Credit Agreement also restricts the Company with respect to the payment of
cash dividends, the sale of assets, mergers and acquisitions, additional
financing, and investments.

At June 30, 1999, the Company had $5.5 million outstanding in
equipment-collateralized financing facilities and $5.7 million outstanding in
foreign unsecured term loans. The Company had an additional $23.9 million of
unsecured revolving credit facilities from financial institutions at foreign
locations, of which at June 30, 1999, $15.0 million was outstanding.

At December 31, 1999, the Company had $20.4 million in foreign revolving
lines of credit, against which $13.5 million had been borrowed. Foreign term
loan facilities of $3.6 million and equipment financing facilities of
$4.8 million were both fully utilized. As of December 31, 1999, the Company had
$253.8 million under its credit facilities, against which $174.1 million had
been borrowed.

The following is a summary of the Company's long-term debt and other loans
at June 30, 1998 and 1999 and at December 31, 1999 (in thousands):

As of June 30, 1999, scheduled principal payments on long-term debt are as
follows: fiscal 2000: $8,047,000; fiscal 2001: $11,775,000; fiscal 2002:
$9,810,000; fiscal 2003: $14,708,000; fiscal 2004: $16,997,000; and $105,128,000
thereafter.

During fiscal 1997, 1998 and 1999, the Company incurred interest expense,
net of capitalized interest, of $7,357,000, $10,060,000 and $12,703,000,
respectively. During the six months ended December 31, 1998 and 1999, the
Company incurred interest expense, net of capitalized interest, of $7,124,000
and $8,140,000, respectively.

In accordance with SFAS No. 107 "Disclosures About Fair Value of Financial
Instruments," the fair values of the Company's debt have been estimated based on
current rates offered to the Company for debt of the same remaining maturities.
The carrying amounts of the loans to the Company approximate their fair values.

3. CAPITAL STOCK

EMPLOYEE STOCK PURCHASE PLAN

The Company has a compensatory employee stock purchase plan ("ESPP"). Under
this plan employees are allowed to designate between two and ten percent of
their eligible compensation to purchase shares of the Company's common stock at
85 percent of fair market value at a designated date. During fiscal 1997, 1998
and 1999, 182,190, 216,655, and 344,177 shares were purchased at weighted
average per share exercise prices of $13.66, $11.07 and $6.93, respectively.
Shares authorized under this plan that remained unissued were 1,657,541,
1,440,886 and 1,096,709 at June 30, 1997, 1998 and 1999, respectively. The
weighted average per share fair value of ESPP options granted, using the
Black-Scholes method, in 1997, 1998 and 1999 was $5.54, $4.31 and $2.84 per
share, respectively.

STOCK OPTION PLANS

The Company has four stock option plans, the Stock Option Plan of 1984 (as
amended) ("1984 Plan"), the Amended and Restated Stock Incentive Plan of 1992
("1992 Plan"), the 1997 Employee Stock Incentive Plan ("1997 Plan") and the 2000
Stock Incentive Plan ("2000 Plan"). Under the 1984 Plan and the 1992 Plan,
options to purchase shares of the Company's common stock may be granted to the
Company's employees, including executive officers, and to members of the
Company's Board of Directors. Under the 1997 Plan, options to purchase shares of
the Company's common stock may be granted to the Company's employees and
consultants, but not to executive officers of the Company or members of its
Board of Directors. Under the 2000 Plan, options to purchase shares of the
Company's common stock may be granted to the Company's employees, officers,
directors, and consultants and advisors. Options have been issued with an
exercise price at least equal to the fair value of the Company's common stock at
the date of grant ("at market") and become generally exercisable in annual
installments of 20%, beginning on the first anniversary date.

The 1984 Plan terminated in August 1994. As of June 1999, there are no
remaining options outstanding under the 1984 Plan. During fiscal 1997, 1998 and
1999, 2,400, 2,800 and 14,000 shares, respectively, expired under the 1984 Plan.

In November 1996, the stockholders of the Company approved an amendment to
the stock option plan of 1992. The amendment broadened the types of options and
other stock-based awards (e.g.,

restricted stock, SARs and performance shares) that may be granted (prior to the
amendment, only non-qualified options could be granted), extended the term of
the 1992 Plan for three years to December 31, 2002, retained the provision for
the annual increase in shares of the Company's common stock available for grant
of 1.5% of outstanding shares, increased the maximum number of shares that may
be granted to non-employee directors from 100,000 to 120,000 (including an
annual grant of 5,000 shares to each such director), reduced the holding period
for full vesting of certain non-employee director options from one year to six
months, and generally provided the committee of the Board of Directors that
administers the 1992 Plan with substantial powers and discretion in respect to
awards. During fiscal 1998 and 1999, only non-qualified options were issued, at
market, under the 1992 Plan. On January 1, 1997, 1998 and 1999, 764,078, 767,928
and 773,019 shares, respectively, were added to the 1992 Plan.

The Board of Directors adopted the 1997 Plan in November 1997. The terms of
the options authorized and granted under the 1997 Plan are substantially similar
to those under the 1992 Plan. As of June 30 and December 31, 1999, there are
826,100 and 62,650 shares, respectively, available for future grants to eligible
employees; no awards may be granted after December 31, 2002. Executive officers
and directors are not eligible for grants under the 1997 Plan. During fiscal
1998 and 1999, only non-qualified options were issued under the 1997 Plan.

In November 1999, the stockholders of the Company approved the 2000 Plan.
The 2000 Plan is effective as of January 1, 2000, and there are 4,500,000 shares
available for future grants to eligible persons. No awards may be granted under
the 2000 Plan after December 31, 2009. As of December 31, 1999, no options have
been issued.

SHAREHOLDER RIGHTS PLAN

On August 2, 1996, the Company's Board of Directors adopted a Shareholder
Rights Plan (the "Plan") under which preferred stock purchase rights (the
"Rights") have been and will continue to be granted for each outstanding share
of the Company's common stock held at the close of business on August 14, 1996.
The Plan is intended to ensure fair and equitable treatment for all shareholders
in the event of unsolicited attempts to acquire the Company.

The Rights will become exercisable ten days after a person or group (the
"Acquiror") has acquired beneficial ownership of 20% or more of the Company's
common stock other than pursuant to a qualified offer, or announces or commences
a tender offer or exchange offer that could result in the acquisition of
beneficial ownership of 20% or more. Once exercisable, each Right entitles the
holder to purchase one one-thousandth of a share of a new series of preferred
stock at an exercise price of $135, subject to adjustment to prevent dilution.
If the Acquiror acquires 20% or more of the Company's common stock, each Right
(except those held by the Acquiror) entitles the holder to purchase either the
Company's stock or stock in the merged entity at half of market value. The
Rights have no voting power, expire on August 14, 2006, and may be redeemed at a
price of $0.01 per Right up to and including the tenth business day after a
public announcement that 20% or more of the Company's shares have been acquired
by the Acquiror.

The Company amended and restated its Rights Agreement, as of December 15,
1998, to remove the requirement that continuing directors vote in board
approvals of certain corporate transactions.

4. IMPAIRMENT OF ASSETS, RESTRUCTURING AND SEVERANCE CHARGES

Due to a decline in selling prices for its MOSFET and IGBT products, during
the fourth quarter of fiscal 1997, the Company recorded a $75 million pretax
charge related to a restructuring program designed to improve the Company's cost
structure. Specifically, the restructuring activities included

shifting production from older manufacturing facilities to newer, more efficient
facilities, changing business processes by consolidating order entry, customer
support, inventory management, information systems and finance activities at
fewer locations and accelerating the deployment of the Company's new product
development center. The restructuring activities were expected to reduce the
cost of the Company's business processes and lower product costs and result in
increased flow of new products, which are less price sensitive. The charge was
composed of $61 million for the write-down of assets, $4 million for the
write-down of inventory, primarily wafers, to net realizable value and
$10 million for termination benefits to be paid in connection with the severed
employees. The restructuring activities occurred over an approximate
eighteen-month transition period through December 31, 1998.

The asset write-down of property and equipment of $61 million was determined
by comparing the expected future undiscounted cash flows to the respective asset
carrying value. If an asset was deemed to be impaired, the carrying value was
adjusted to its expected future discounted cash flows. The net book value of the
applicable property and equipment prior to the $61 million write-down was
$79 million. The write-downs related to the following:

1) Wafer fabrication equipment located in El Segundo, California with a
carrying value of $21 million was adjusted to its fair value of $2 million. One
wafer fabrication line, dedicated primarily to research and product development,
was abandoned and replaced by a new product development facility in
August 1998. The other wafer fabrication line, which manufactured product using
equipment that processed 4-inch wafers, was abandoned and replaced with a more
advanced line located in Italy, which processes 5-inch wafers, in August 1998.
Using 5-inch wafers results in significant manufacturing savings. The current
status of the wafer fabrication impaired equipment falls into three categories:
a) it was scrapped as of June 1997, b) it is idle with no viable plans for
usage, or c) it is being used on a sporadic basis in research and development.
There is no viable external market for this equipment.

2) Assembly equipment in England of $26 million was adjusted to its fair
value of $4 million. Specifically, three product assembly and packaging lines in
England were operating at a gross margin loss. The Company has continued to
utilize these lines periodically for market development activities, and these
lines remain unprofitable.

3) Information systems applications with a carrying value of $32 million
were written down to $12 million as a result of lack of vendor support. The
Company's software vendor changed business strategies and informed the Company
of its intention to stop supporting and developing the software technology that
certain of the Company's information systems applications were based upon. It
was determined in June 1997 that no viable alternatives could be identified. As
a result of this decision, the Company ceased development and implementation of
certain forecasting, planning and order management programs and determined that
the assets related to these specific activities were impaired (i.e. no future
use and were abandoned). These assets consisted of costs related to external
consulting fees and expenses. The remaining book value relates to modules that
have not been abandoned.

As of June 30, 1999, the Company had eliminated approximately 242 employees
related to the June 1997 restructuring. The majority of the positions eliminated
were operators and technicians at the Company's North American operations. The
Company also eliminated production and assembly positions in its manufacturing
operations in Italy due to the outsourcing of certain assembly activities. In
addition, administrative and sales positions in France, England, Germany, Japan
and North America, related to the regional consolidation of certain
administrative functions, were eliminated.

4. IMPAIRMENT OF ASSETS, RESTRUCTURING AND SEVERANCE CHARGES (CONTINUED)

As of June 30, 1999, there was no remaining accrued severance liability in
the Company's Consolidated Balance Sheet related to the June 1997 restructuring.

During the second quarter of fiscal 1999, the Company recorded a
$14.5 million restructuring charge associated with plans to relocate high-volume
assembly lines from its facility in England to its facility in Mexico to take
advantage of labor rate savings, to centralize more of its European customer
service and administrative activities, and to reduce personnel. The Company
expects to complete this operational transition over the next six months ending
on June 30, 2000. The charge consisted of $5.9 million for estimated severance
costs associated with the elimination of approximately 350 positions, primarily
consisting of operators and technicians; $6.1 million for the write-off of
assets to be abandoned; and $2.5 million, which was charged to Cost of Sales,
for the write-down of inventory related to specialty product lines. None of the
assets written down (primarily building improvements relating to the high-volume
assembly production lines and production information systems) will remain in
use, and all will be abandoned after the production lines are relocated. In the
third quarter of fiscal 1999, the Company recorded a charge of $4.2 million
relating to additional severance costs, after appropriate notification was given
to 43 remaining affected employees in the sales, customer service and
administrative areas. The severance per person was larger for the third-quarter
fiscal 1999 restructuring versus the second-quarter fiscal 1999 restructuring as
the 43 positions included in the third-quarter fiscal 1999 restructuring were
primarily relatively high-paid employees in sales and administrative management.
The 350 positions in the second-quarter fiscal 1999 restructuring were primarily
operators and technicians who on average have a much lower salary level.
Therefore, the Company estimates that, ultimately, charges associated with all
of these actions will total approximately $18.7 million.

As of June 30, 1999, the Company had eliminated 17 positions, paid
$2.8 million for termination benefits related to this program and recorded the
asset impairment of $8.6 million. The remaining unutilized restructuring accrual
of $7.3 million, which is classified as current, relates to severance payments
to these previously notified employees for positions that are scheduled to be
eliminated during the next twelve months. As of December 31, 1999, the Company
had eliminated an additional 47 positions and paid an additional $3.2 million
for termination benefits, leaving a remaining unutilized restructuring accrual
of $4.1 million, which is classified as current.

During the fourth quarter of fiscal 1999, the Company recorded an
$8.3 million charge related to employee severance associated with the
elimination of approximately 39 positions. This includes a reduction in sales
and administrative management and staff levels and the resignation of Dr. Derek
B. Lidow who shared the responsibility of Chief Executive Officer. As of
June 30, 1999, the Company had eliminated 4 positions and paid $3.5 million in
termination benefits. The remaining unutilized severance accrual of
$4.8 million at June 30, 1999, which is classified as current, relates to
severance payments to these previously notified employees for positions that are
scheduled to be eliminated during the next twelve months. As of December 31,
1999, the Company had eliminated an additional 21 positions and paid an
additional $1.4 million in termination benefits, leaving a remaining unutilized
restructuring accrual of $3.4 million, which is classified as current.

The Company's federal net operating loss ("NOL") carryforwards of
$26,614,000 from fiscal 1998 will be fully utilized to offset taxable income in
fiscal 1999. In addition, at June 30, 1999, the Company has approximately
$16,188,000, $1,187,000 and $38,238,000, respectively, of foreign tax credits,
investment tax credits, and research and development tax credit carryforwards,
before valuation allowance, available to reduce income taxes otherwise payable,
which expire from 2000 to 2019. In addition, the Company has approximately
$3,497,000 of alternative minimum tax credits, which can be carried over
indefinitely to offset regular tax liablilities to the extent of the alternative
minimum tax, and a $8,276,000 state tax credit, before valuation allowance,
which expires from 2004 to 2007.

The Company's NOL carryforward benefits of $2,582,000 were generated from
the Company's United Kingdom subsidiary. The NOLs can generally be carried
forward indefinitely, with certain limitations.

Realization of deferred tax assets is dependent upon generating sufficient
taxable income. Management believes that there is a risk that certain deferred
tax assets may result in no benefit and, accordingly, has established a
valuation allowance of $31,812,000 against them at June 30, 1999. Although
realization is not assured for the remaining deferred tax assets, management
believes it is more likely than not that they will be realized through future
taxable earnings or alternative tax strategies.

The Internal Revenue Service is currently auditing the Company's income tax
returns for fiscal 1995 through 1997. Management believes that resolution of the
audit will not have a material impact on the Company's consolidated financial
position, results of operations or cash flows.

The Company previously had a defined contribution plan for all eligible
employees ("The Profit Sharing and Retirement Plan"). This plan provided for
contributions by the Company in such amounts as the Board of Directors
determined annually. Effective November 1, 1996, the Company elected to
terminate its Profit Sharing and Retirement Plan in order to focus on
improvements in its voluntary Retirement Savings Plan (401K). Employees and
former employees not fully vested at the time of the plan termination became
100% vested and were given various distribution options as defined by

ERISA. Under the established Retirement Savings Plan (401K), the Company made an
annual contribution for each participating employee of up to $1,200 in fiscal
1997, 1998 and 1999. Combined plan contributions by the Company totaled
$1,365,000, $1,261,000 and $1,174,000 for fiscal 1997, 1998 and 1999,
respectively.

9. ENVIRONMENTAL MATTERS

Federal, state, and local laws and regulations impose various restrictions
and controls on the storage, use and discharge of certain materials, chemicals,
and gases used in semiconductor manufacturing processes. The Company does not
believe that compliance with such laws and regulations as now in effect will
have a material adverse effect on the Company's results of operations, financial
position or cash flows.

However, under some of these laws and regulations, the Company could be held
financially responsible for remedial measures if properties are contaminated, or
if waste is sent to a landfill or recycling facility that becomes contaminated.
Also, the Company may be subject to common law claims if it releases substances
that damage or harm third parties. The Company cannot make assurances that
changes in environmental laws and regulations will not require additional
investments in capital equipment and the implementation of additional compliance
programs in the future which could have a material adverse effect on the
Company's results of operations, financial position or cash flows, as could any
failure by the Company to comply with environmental laws and regulations.

The Company and Rachelle Laboratories, Inc. ("Rachelle"), a former operating
subsidiary of the Company that discontinued operations in 1986, were each named
a potentially responsible party ("PRP") in connection with the investigation by
the United States Environmental Protection Agency ("EPA") of the disposal of
allegedly hazardous substances at a major superfund site in Monterey Park,
California ("OII Site"). Certain PRPs who settled certain claims with the EPA
under consent decrees filed suit in Federal Court in May 1992 against a number
of other PRPs, including the Company, for cost recovery and contribution under
the provisions of the Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA"). The Company has settled all outstanding claims that
have arisen out of the OII Site. No claims against Rachelle have been settled.

The Company received a letter, directed to Rachelle, dated July 25, 1995,
from the U.S. Department of Justice offering to settle claims against Rachelle
relating to the first elements of clean-up work at the OII Site for $4,953,148
(the final remedy assessment has not yet been made). The offer stated that the
settlement would not cover the cost of any additional remedial actions required
to finish the clean-up. This settlement offer expired by its terms on
September 1, 1995. On August 7, 1995, the Company received a Supplemental
Information Request from the EPA directed to Rachelle, to which counsel for
Rachelle responded with information regarding waste shipped to the OII Site.
Counsel for Rachelle received a letter from the EPA dated September 30, 1997,
requesting that Rachelle participate in the final remedial actions at the site,
and counsel replied on October 21, 1997. The Company has taken the position that
none of the wastes generated by Rachelle were hazardous. Neither the Company nor
Rachelle, nor counsel for either of them, have received any further
communication in connection with Rachelle's involvement with the OII Site.

9. ENVIRONMENTAL MATTERS (CONTINUED)

The Company cannot determine with accuracy the amount of the potential
demand to Rachelle for the cost of the final remedy. Based upon information
received to date, the Company believes that any demand for the cost of the final
remedy would, if made, likely be significant, although it should be
substantially below the demand amount for earlier phases of the OII Site
clean-up. Any demands related to the costs for the final remedy would be in
addition to the amount demanded for earlier phases of the OII Site clean-up. The
Company's insurer has not accepted liability although it has made payments for
defense costs for the lawsuit against the Company.

The Company received a letter dated September 9, 1994, from the State of
California Department of Toxic Substances Control stating that it may be a PRP
for the deposit of hazardous substances at a facility in Whittier, California.
In June 1995, the Company joined a group of other PRPs to remove contamination
from the site. The group currently estimates the total cost of the clean-up to
be between $20 million and $25 million, although the actual cost could be much
higher. The Company estimated that it sent approximately 0.1% of the waste, by
weight, sent by all PRPs contributing to the clean-up of the site, and the
Company believes the cost of the clean-up will be roughly allocated among PRPs
by the amount of waste contributed. On July 31, 1999, the group proposed two
settlement offers to the Company: one for $34,165 and the second for $68,330.
The first settlement offer covers investigation and remediation of the site
itself and a small area extending beyond the site. The second settlement offer
covers this area plus all additional downgradient contamination. On
September 14, 1999, the Company accepted the $68,330 settlement offer, which
requires EPA acceptance, and made the required payment on September 28, 1999.
There can be no assurance, however, that the EPA will accept the settlement
offers or what the ultimate outcome of this matter will be. The Company believes
that, whatever the outcome, it will not have a material adverse effect on the
Company's financial condition, results of operations or cash flows.

10. COMMITMENTS

The future minimum lease commitments under non-cancelable capital and
operating leases of equipment and real property at June 30, 1999 are as follows

expense on operating leases charged to income was $3,308,000 and $2,709,000,
respectively.

10. COMMITMENTS (CONTINUED)

The Company had outstanding purchase commitments for capital expenditures of
approximately $10.1 million at June 30, 1999 and approximately $18.8 million at
December 31, 1999.

11. INTELLECTUAL PROPERTY RIGHTS

Most of the Company's broadest power MOSFET patents were subject to, and
have successfully emerged from, reexamination by the United States Patent and
Trademark Office ("PTO"). The Company's 5,130,767 patent is currently undergoing
reexamination in the PTO.

12. OTHER INCOME (EXPENSE)

Other income was $53.5 million in fiscal 1999, compared to other expense of
$0.5 million in fiscal 1998 and other income of $0.7 million in fiscal 1997.
Fiscal 1999 other income primarily consisted of proceeds from license agreements
for prior periods and amounts in settlement of litigation for past patent
infringement (net of legal costs and the share of the Company's royalty proceeds
payable to Unitrode Corporation).

In December 1998, the Company entered into licensing agreements with two
competitors, Samsung Semiconductor, Inc. and Samsung Electronics Co., Ltd.,
(together "Samsung") and Fuji Electric Co., Ltd. ("Fuji"), with respect to the
Company's power MOSFET/IGBT patents. The respective agreements provide for
payments of royalties for prior periods. The agreement with Samsung also
provides for a paid-up license that expired in April 1999. The agreement with
Fuji provides for ongoing royalties on worldwide sales covered by the licensed
patents of the Company.

In March 1999, the Company entered into a licensing agreement with
Shindengen Electric Company. The agreement, effective as of January 1, 1999,
provided for payments of royalties for prior periods, as well as ongoing
royalties on worldwide sales covered by the licensed patents of the Company.

In June 1999, the Company entered into a licensing agreement with Rohm
Co., Ltd. The agreement provides for payments of royalties for prior periods, as
well as ongoing royalties on worldwide sales covered by the licensed patents of
the Company.

13. LITIGATION

On December 6, 1999, the Company filed suit in Federal District Court in Los
Angeles, California against Semiconductor Components Industries, LLC, dba ON
Semiconductor, alleging infringement of certain of the Company's U.S. patents.
The suit seeks damages and customary relief in such matters.

The Company, along with 87 other companies, was sued in Phoenix, Arizona
federal court on February 26, 1999, by the Lemelson Foundation for alleged
infringement of various Lemelson "machine-vision" and "auto ID" patents. In
July 1999, the Company entered into an agreement with the Lemelson Foundation
that settled all outstanding claims and grants the Company a license to use the
Lemelson patents asserted against the Company.

The Company and certain of its directors and officers have been named as
defendants in three class action lawsuits filed in Federal District Court for
the Central District of California in 1991. These

13. LITIGATION (CONTINUED)

suits seek unspecified but substantial compensatory and punitive damages for
alleged intentional and negligent misrepresentations and violations of the
federal securities laws in connection with the public offering of the Company's
common stock completed in April 1991 and the redemption and conversion in
June 1991 of the Company's 9% Convertible Subordinated Debentures due 2010. They
also allege that the Company's projections for growth in fiscal 1992 were
materially misleading. Two of these suits also named the Company's underwriters,
Kidder, Peabody & Co. Incorporated and Montgomery Securities, as defendants.

On March 31, 1997, the Court, on the Company and the individual defendants'
motion for summary judgment, issued the following orders: (a) the motion for
summary judgment was granted as to claims brought under Sections 11 and 12(2) of
the Securities Act of 1933; (b) the motion was denied as to claims brought under
Section 10(b) of the Securities Exchange Act of 1934 and the Securities and
Exchange Commission Rule 10b-5; and (c) the motion was granted as to the common
law claims for fraud and negligent misrepresentation to the extent said claims
are based on representations contained in the prospectuses and was denied in all
other respects. The Court also granted the summary judgment motion brought by
the underwriters. The plaintiffs' motion for reconsideration or certification of
an interlocutory appeal of these orders was denied.

On January 28, 1998, the Court decertified the class pursuing common law
claims for fraud and negligent misrepresentation and granted the defendants'
motion to narrow the shareholder class period to June 19, 1991 through
October 21, 1991. Plaintiffs' motion for reconsideration or certification of an
interlocutory appeal of these rulings was denied.

On June 14, 1999, the Court approved a notice of the pendency of the class
action and a proof of claim form for dissemination to class members. Such
dissemination took place in June 1999. Trial is scheduled for March 14, 2000.

Although the Company believes that the remaining claims alleged in the suits
are without merit, the ultimate outcome cannot be presently determined. A
substantial judgment or settlement, if any, could have a material adverse effect
on the Company's results of operations, financial position or cash flows. No
provision for any liability that may result upon adjudication of these matters
has been made in the Consolidated Financial Statements.

14. EXECUTIVE AGREEMENT

The Company entered into an executive agreement with Eric Lidow dated
May 15, 1991. The agreement set Mr. Lidow's annual salary at $500,000, granted
the Board discretion to increase his salary and to pay him bonuses, and
established a pension. Mr. Lidow's salary was increased in May 1992 to $550,000,
in August 1994 to $632,500 and in July 1999 to $670,450. Mr. Lidow was not
awarded a bonus in fiscal 1999. The agreement may be terminated by either party
upon 90 days written notice.

SIX MONTHS ENDED DECEMBER 31, 1998 AND 1999 IS UNAUDITED

14. EXECUTIVE AGREEMENT (CONTINUED)

Under the agreement, prior to its amendment described below, Mr. Lidow would
have been entitled to begin receiving the pension payments when his employment
with the Company ceased for any reason (except termination for cause). The
pension would have been payable in annual installments, equal to the sum of 90%
of his then current salary and the average of his prior three years' cash
bonuses, if any. If Mr. Lidow's wife survived him, she would have received, for
the remainder of her life, annual payments in an amount equal to two-thirds of
the amount of the pension payment that would have been payable to Mr. Lidow.
Before the amendments to the agreement described below, if Mr. Lidow had retired
at fiscal 1998 year-end, the pension would have been equal to $821,250 per year
for the remainder of Mr. Lidow's life and $547,500 per year for the remainder of
Mrs. Lidow's life, if she had survived him. The Company had funded a trust to
cover its liability for the pension based on actuarial assumptions established
by PricewaterhouseCoopers LLP. However, the Company's actual liability for the
pension in ensuing years could have been more or less than the funding depending
upon whether actual events mirrored the actuarial assumptions.

In fiscal 1998, the Company's Compensation Committee and Mr. Lidow
renegotiated his executive agreement. The Compensation Committee then
recommended adoption of the renegotiated agreement by the Board, which the Board
approved. In taking these actions, the Compensation Committee and the Board
considered, among other things, their and Mr. Lidow's desire to limit the sale
of his shares of the Company's Common Stock to meet commitments and their
concerns about the uncertainty of the Company's liability for the pension. In
connection with the former consideration, the Company also made certain loans to
Mr. Lidow, which have since been repaid. See Note 15 in the Notes to the
Consolidated Financial Statements. The amendments to Mr. Lidow's agreement
canceled all of the Company's obligations with respect to the pension. As
consideration, the corpus of the trust of $8,096,663 was distributed to
Mr. Lidow in several installments, $1,500,000 and $6,596,663 in fiscal 1998 and
1999, respectively. Based on actuarial analysis, the consideration was less than
the amount needed to purchase the retirement benefit from a third party company.
Mr. Lidow and his wife are not entitled to receive any additional pension
payments under the agreement.

The funding of the pension had been expensed in prior years, and the lump
sum distribution did not trigger any further expense. Because Internal Revenue
Code Section 162(m) imposes certain restrictions on the deductibility of
non-performance based compensation in excess of $1,000,000, the Company was not
able to deduct any compensation in excess of $1,000,000 paid to Mr. Lidow in
fiscal 1998 and 1999.

15. RELATED PARTIES

In June 1998, after discussing with Eric Lidow his desire to limit his sale
of shares of IR Common Stock to meet commitments, the Board approved two
unsecured loans to him aggregating $1,200,000, with interest at the annual rate
of eight and one-half percent (8.5%). The first loan of $600,000 was made in
June 1998 and the second loan, also for $600,000, was made in July 1998. Both
loans were due December 31, 1998. Mr. Lidow repaid them with accrued interest of
$23,497 on September 23, 1998. Contemporaneously with the approval of the loans,
the Company amended his executive agreement. (See Note 14 in the Notes to the
Consolidated Financial Statements).

15. RELATED PARTIES (CONTINUED)

In May 1999, after considering the recommendation of the Chairman and Chief
Executive Officers, the Board determined that the Company should implement a
single CEO management structure. To effectuate this management change, the
Company entered into an agreement with Dr. Derek B. Lidow on May 10, 1999
("Agreement"), which provided for Dr. Lidow's resignation as Chief Executive
Officer and as an employee of the Company. Under the terms of the Agreement,
Dr. Lidow received a severance payment of $3,200,000 on June 15, 1999, a bonus
of $100,000 for fiscal 1999 performance on August 13, 1999 and a grant of
200,000 stock options on June 14, 1999, which were fully vested, and which
expire on June 13, 2009. The Agreement also provided for the immediate
acceleration of the vesting of all of Dr. Lidow's outstanding unvested stock
options and extended the period during which the options could be exercised.
Under the Agreement, Dr. Lidow will provide consulting services to the Company
for a period of two years for which he will be compensated $100,000 per quarter
plus associated expenses.

In connection with Dr. Derek B. Lidow's exercise of an option on June 23,
1999 to purchase 64,000 shares of the Common Stock of the Company, the Company
had an outstanding receivable from Dr. Lidow for $597,694 at June 30, 1999,
which was paid off on July 7, 1999.

During fiscal year 1999, the Company paid $310,160 to the Law Offices of
Janet K. Hart for legal and negotiation services rendered to the Company.
Ms. Hart is the wife of Dr. Alexander Lidow.

16. RESTATEMENT

As discussed in Note 1 in the Consolidated Financial Statements, Recent
Accounting Pronouncements section, in fiscal 1999 the Company reported a
non-cash, after-tax charge of $26.2 million associated with the early adoption
of SOP 98-5, a required change in accounting practices for certain start-up and
preoperating costs. Therefore, the six months ended December 31, 1998 have been
restated to reflect the above charge.

17. ACQUISITION

On January 28, 2000, the Company and Zing Technologies, Inc. ("Zing")
announced that the Company agreed to acquire all the outstanding shares of Zing
for a cash purchase price of $15.36 per share. Zing's wholly owned subsidiary
and sole operating business, Omnirel LLC, supplies power semiconductor modules
and components. The net cash purchase price (net of Zing Technologies, Inc.'s
cash) for the transaction is $28.5 million. Net sales for the Omnirel LLC
operating unit of Zing for the fiscal year ended June 30, 1999 were
approximately $25 million. The Company commenced a cash tender offer in February
and expects to complete the transaction in the quarter ended March 31, 2000.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

As permitted by Section 145 of the General Corporation Law of Delaware, our
bylaws provide for indemnification of our directors, employees and agents
against expenses (including attorneys' fees) and other amounts paid in
settlement actually and reasonably incurred by them in connection with any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the company), in which any such person was or is a party or is
threatened to be made a party. However, indemnification is only permitted if
(a) such person acted in good faith and in a manner such person reasonably
believed to be in or not opposed to our best interest and (b) with respect to
any criminal action or proceeding, if such person had no reasonable cause to
believe his conduct was unlawful. In the case of an action or suit by or in the
right of the company, we may not indemnify such person in respect of any claim,
issue or matter as to which he has been adjudged liable for negligence or
misconduct in the performance of his duty to us, unless and only to the extent
the court in which such action or suit was brought or the Court of Chancery
determines that such person is fairly and reasonably entitled to indemnity for
such expenses as such court may deem proper. In each case, indemnification will
be made only upon specific authorization of a majority of disinterested
directors, by written opinion of independent legal counsel or by the
stockholders, unless the director, officer, employee or agent has been
successful on the merits or otherwise in defense of any action or suit, in which
case he will be indemnified without such authorization. Our bylaws (a) require
us to pay the expenses incurred by a director or officer in defending or
investigating a threatened or pending action, suit or proceeding in advance of
the final disposition of such action, suit or proceeding upon our receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it is ultimately determined that he is not entitled to indemnification and
(b) permit us to advance such expenses to other of our employees and agents upon
such terms and conditions specified by our board of directors. The advancement
of expenses, as well as indemnification, pursuant to our bylaws, is not
exclusive of any other rights which those seeking indemnification or advancement
of expenses from us may have.

II-1
<PAGE>
ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS (CONTINUED)

Our certificate of incorporation eliminates personal liability of our
directors to us or our stockholders for monetary damages for breach of fiduciary
duty as director, except for:

(a) any breach of the duty of loyalty to us or our stockholders;

(b) acts or omissions not in good faith or which involve intentional
misconduct or knowing violations of law;

(c) liability under Section 174 of the Delaware General Corporation Law
relating to unlawful dividends and stock repurchases; or

(d) any transaction from which the director derived an improper personal
benefit.

Our bylaws permit us to purchase and maintain insurance on behalf of our
directors, officers, employees or agents against liability asserted against such
person in any such capacity, whether or not we would have the power to indemnify
him or her against such liability under the provisions of our bylaws. However,
we maintain liability insurance providing coverage only with respect to claims
made against officers and directors as to which they are entitled to be
indemnified by us.

We have a policy of directors and officers liability insurance which insures
our directors and officers against the costs of defense, settlement or payment
of a judgment under specified circumstances.

ITEM 17. UNDERTAKINGS

(b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933 (the "Securities
Act") each filing of the Registrant's annual report pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
Registration Statement will be deemed to be a

ITEM 17. UNDERTAKINGS (CONTINUED)

new registration statement relating to the securities offered therein, and the
offering of such securities at that time will be deemed to be the initial bona
fide offering thereof.

(h) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

(i) The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act,
the information omitted from the form of Prospectus filed as part of
this Registration Statement in reliance upon II-2 Rule 430A and
contained in a form of Prospectus filed by the Registrant pursuant to
Rule 424(b)(1) or (4) or Rule 497(h) under the Securities Act shall
be deemed to be part of this Registration Statement as of the time it
was declared effective; and

(2) For the purpose of determining any liability under the Securities
Act, each post-effective amendment that contains a form of Prospectus
shall be deemed to be a new Registration Statement relating to the
securities offered therein, and the offering of such securities at
that time shall be deemed to be the initial bona fide offering
thereof.
