ITEM 1. BUSINESS
INTRODUCTION
International Rectifier Corporation ("IR" or the "Company") is a major worldwide supplier of power semiconductors. Power semiconductors switch or condition electricity at relatively high voltage and current levels in products such as computers/peripherals, automobiles, portable phones, and electronic lights.
The Company designs, manufactures and markets power semiconductors which are used for power conversion. In the same way that oil is refined to produce gasoline to power a car, electrical power is converted to operate equipment. This process of power conversion can be viewed in four stages: input rectification, control, switching, and output rectification. Input rectification conditions off-line electricity, typically rectifying alternating-current to direct-current. The control function measures incoming electricity and sends a signal to the switch. The switch chops the energy into small elements. Output rectification re-configures the elements into a form usable by electrically operated equipment.
IR supplies products that perform each of the four basic functions in power conversion, and many circuits use more than one type of IR product. This allows IR to develop products that work together to optimize overall circuit performance, and enables the Company to capitalize more broadly on market- leading products.
IR's products are used in all major market sectors. Applications for power semiconductors in automobiles include anti-lock braking and fuel injection systems, power accessories, and air bags. Computer/peripheral applications include power supplies, disk drives, and printers. Office equipment applications include copiers and facsimile machines. Consumer electronics and lighting applications include home entertainment, household appliances and electronic lighting ballasts. Communications applications include portable phones, telephone networks and modems. Power semiconductors are also used widely in industrial applications such as motor-driven production lines, machine tools, fork lifts, and welders.
Based on statistics published by the Semiconductor Industry Association (the "SIA"), the Company believes it is the leader in the power MOSFET (Metal Oxide Semiconductor Field Effect Transistor) segment with its trademarked HEXFET-Registered Trademark- power MOSFETs and IGBTs (Insulated Gate Bipolar Transistors). SIA data indicates that industry-wide sales of power MOSFETs were $1.5 billion in calendar 1994, an increase of 38% over 1993 levels, and that, over the past five years, power MOSFET sales have grown at an average rate of 28% per year.
The Company's major customers include industry leaders such as AT&T Technologies Inc., Conner Peripherals, Inc., General Motors Corp., Hewlett Packard Co., International Business Machines Corp., Matsushita Electronics Corporation, Sanken Electric Company, Ltd., Sony Corporation, Sporele and Siemens AG. In fiscal year 1995 the Company's sales by region were approximately 46% from North America, 28% from Europe, and 26% from Asia. IR has manufacturing facilities in North America, Europe, and Asia, and uses subcontract assembly in Asia.
IR was founded as a California corporation in 1947 and reincorporated in Delaware in 1979. Its executive offices are located at 233 Kansas Street, El Segundo, California 90245 and its telephone number is (310) 322-3331.
POWER SEMICONDUCTOR INDUSTRY
Semiconductors are silicon-based chips that conduct and block electricity. The semiconductor industry consists of integrated circuits ("ICs") and power semiconductors. ICs operate at low power levels and perform multiple functions to process and convey information in electronic signal form. IC capability is largely defined by circuit density, which increases as its features are miniaturized. The
applications for ICs are generally concentrated in the computer industry and have been subject to frequent redesign, short product life cycles and rapid obsolescence. As a result, the demand for ICs has been highly cyclical.
In contrast to ICs, power semiconductors operate at higher power levels and perform a single function: they condition and control electricity to operate a power supply, control a motor, or light a lamp. Their capability is largely defined by the level of power that they can handle and their efficiency in converting raw electric current into a more useful form. The amount of electric current handled and the heat it generates limit the rate at which power semiconductors can be miniaturized.
Advances in power semiconductor performance and cost-per-function have been achieved through the use of MOS technology. MOS power transistors (power MOSFETs and IGBTs) have gained an increasing share of the power transistor market at the expense of bipolar transistors that also serve the switch function.
MOS power transistors offer significant benefits over bipolar power transistors. They provide much greater switching speed, which allows the design of higher frequency, more compact circuits. They are activated by voltage rather than current, so they require less external circuitry. MOS transistors are more compatible with microprocessor controls. They offer more reliable long-term performance and are more rugged, so they can better withstand adverse operating conditions. Power MOSFETs and IGBTs compare favorably to bipolar power transistors on a price/performance basis.
APPLICATIONS
Power semiconductors are used in a broad spectrum of commercial and industrial applications, including many products with long life cycles. Because of their more gradual rate of technological change and the diversity of applications, the demand for power semiconductors is less cyclical than for ICs. Power semiconductor demand is driven by conversion to new technologies, the proliferation of new end-product applications, and growth in the end markets. The Company believes that markets driving future demand for power semiconductors include:
PORTABLE ELECTRONICS. Advances in power semiconductors help extend battery life and reduce product size and weight in a variety of battery-operated products such as lap-top and notebook computers, personal digital organizers, cellular telephones, household appliances and hand tools.
AUTOMOTIVE ELECTRONIC SYSTEMS. The concentration of solid state electronics in recent model year automobiles has increased rapidly, as safety and comfort features increase demands on the battery. Applications include anti-lock braking systems, air-bags, fuel injection systems, electric windows and adjustable mirrors and seats. Adoption of battery operated electric vehicles to reduce emissions would dramatically increase consumption of MOS transistors.
ELECTRONIC LIGHTING BALLASTS. Electronic lighting ballasts, which incorporate power MOSFETs and Power Integrated Circuits, significantly reduce the amount of energy consumed in lighting. Conversion to electronic ballasts has been driven by lower end-user operating costs and incentives from electric utilities to encourage energy efficiency.
VARIABLE SPEED MOTORS. Variable-speed solid-state controls increase energy efficiency and performance in a broad range of industrial and appliance motors. In addition, clean air legislation is driving the conversion from traditional chlorofluorocarbons ("CFCs") to less toxic refrigerants which are also less efficient. Manufacturers of refrigerators and air conditioners can compensate for these less efficient chemicals by using more efficient variable-speed motors.
PRODUCTS
The Company's products convert electrical power to make it more useable and efficient in performing work such as operating power supplies, controlling motors, and lighting lamps. The products' ability to minimize energy lost at each point in the power conversion process is central to
their value. Important growth applications include such energy-sensitive products as electronic fluorescent lights, more energy efficient refrigeration and air conditioning equipment, and electric vehicles.
The Company's HEXFET power MOSFET products comprised about 66% of fiscal 1995 sales. IR also supplies IGBT transistors, High Voltage Control Integrated Circuits, high-performance diodes, and high power rectifiers and thyristors. The Company believes that this complete line of power conversion products represents a competitive advantage, enabling IR to provide customers with integrated solutions to their power conversion needs.
SWITCHING PRODUCTS
MOS TRANSISTORS. MOS transistors (power MOSFETs and IGBTs) serve the switch function in power conversion to provide an even, usable flow of power for electronic equipment.
POWER MOSFETS. Through its HEXFET product line, the Company is the world leader in power MOSFETs. The breadth and diversity of the market for these products help to stabilize demand.
Applications for MOSFETs in automobiles include anti-lock braking and fuel injection systems, power accessories and air bags. Computer/peripheral applications include power supplies, disk drives, and printers. Office equipment applications include copiers and facsimile machines. Consumer electronics applications include home entertainment, videocameras, household appliances, and power tools. Lighting applications include electronic lighting ballasts and compact fluorescent bulbs. Industrial applications include instrumentation and test equipment. Communications applications include telephone networks and modems. Government and aerospace applications include commercial and military satellites, communications equipment, command-and-control systems, and missiles.
Market acceptance and brand recognition of HEXFETs have benefited from the Company's emphasis on quality control and reliability, and the Company believes its standards to be among the most stringent in the industry. Cumulative and current data on long and short term product reliability is made available to customers quarterly.
The Company fabricates the large majority of its power MOSFET wafers at HEXFET America. Die from these wafers are assembled into packaged devices at HEXFET America, IR's facilities in England and Mexico, and subcontract facilities in Asia. See "-- Manufacturing."
IGBTS. IGBTs typically serve the switch function in power conversion applications that require higher current and voltage than power MOSFETs handle efficiently. IGBTs combine the ease of voltage-driven power MOSFET technology with the conduction efficiency of bipolar transistor technology. 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 the Company believes electric vehicles will require large quantities of IGBTs for each vehicle.
The Company's IGBT technology is closely related to its HEXFET technology, and the Company views them as complementary products. The Company believes that its patents on fundamental MOSFET technology also apply to IGBTs, and it is seeking further patent protection on its IGBT technology.
CONTROL PRODUCTS
HIGH VOLTAGE CONTROL ICS. These devices serve the control function of power conversion. They perform the functions of several discrete components. This integration allows IR's customers to simplify circuit design and assembly, improve reliability and reduce overall system size and cost. In sensing and responding to adverse operating conditions, High Voltage Control IC performance is superior to that of discrete components in a safety or diagnostic circuit. IR's High Voltage Control ICs draw on the Company's MOSFET technology and are designed to optimize the performance of both power MOSFETs and IGBTs. The Company believes that its power MOSFET patents also apply to a broad range of High Voltage Control ICs.
High Voltage Control ICs are used in a wide variety of power supply, motor and lighting control applications. These include industrial motor controls, home appliance motor controls, solenoid drivers, welding equipment, telecom switchers, computer/peripherals, instrumentation and test equipment, electronic lighting ballasts, and compact fluorescent light bulbs.
INPUT RECTIFICATION PRODUCTS
The Company also manufactures a broad line of rectifiers, diodes and thyristors that serve the input rectification function of power conversion. These products condition power to make it more efficient and useable, principally in industrial end products that require power-handling capability from one amp to 5000 amps and from 20 volts to 5000 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.
OUTPUT RECTIFICATION PRODUCTS
The Company's Schottky diodes and Fast-Recovery diodes serve the output rectification function of power conversion. Output rectification reconfigures the elements into a form usable by electrically operated equipment. Schottky diodes are used with power MOSFETs in high-frequency applications such as computer/peripherals. The Company's trademarked 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 (or packaging). Wafer fabrication is 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 (often termed "die" or "chips") on each wafer. Packaging or assembly is the sequence of production steps that divide the wafer into individual chips and enclose the chips in external structures (termed packages) that make them useable in a circuit. Power semiconductors generally use the process technology and equipment already proven in ICs manufacturing.
The Company has production facilities in California, England, Italy, Mexico and India. In addition, the Company has equipment at, or manufacturing supply agreements with, subcontractors located in the Philippines, Japan, Taiwan, Malaysia, and the United States.
IR fabricates substantially all of its power MOSFET wafers at HEXFET America in Temecula, California. A wafer fabrication facility for IGBTs and other MOSFET devices as well as assembly operations for government and other advanced products are located in El Segundo, California. Facilities that assemble HEXFETs and other products are located in the United States and overseas, in Company-owned and subcontract facilities, in order to take advantage of low assembly costs and provide maximum customer service. In Tijuana, Mexico, the Company assembles MOSFET products, IGBTs and other modules. The Company's Oxted, England facility, which qualifies as a duty-free facility, assembles MOSFETs, IGBTs, Schottky and diodes. Since April 1, 1994 the Company has manufactured substantially all its high power rectifiers and thyristors at its Turin, Italy facility. The Company also has arrangements with third parties for product assembly in the Philippines, Malaysia, Taiwan, Japan and Mexico. In a duty-free zone in India, the Company has an assembly facility for rectifiers and thyristors.
To meet rising demand for power MOSFETs, the Company is expanding wafer fabrication at HEXFET America. The Company believes that the estimated $75 million expansion will increase its power MOSFET fabrication capacity by about 75% and is expected to support about $185 million in additional product shipments at full utilization.
The expansion will position IR to aggressively address the fastest growing segments of the power transistor market, high density MOSFETs and IGBTs. Next-generation devices designed for production in the new fabrication facility incorporate design and process advancements in the Company's proprietary HEXFET and IGBT technologies. A core process with shared elements for both products
will enable the facility to combine flexibility with efficient high-volume manufacturing techniques. The fabrication will be performed on six-inch wafers and will use a continuous-flow layout similar to the one already in use at HEXFET America. The expansion is on schedule and within budget at this time. The Company has completed substantially all equipment installation and has begun internal qualification and operator and technician training. Customer qualifications are expected to begin in September, and manufacturing is scheduled to begin to ramp up by the end of the calendar year.
Shortly after the close of the fiscal year, IR announced plans to transfer assembly lines from HEXFET America to its assembly facility in Tijuana, Mexico and to independent subcontractors. Designed to allow the California plant to focus on expansion of its benchmark wafer fabrication capability and to reduce the cost of assembling the Company's HEXFET-Registered Trademark- power MOSFET chips into finished devices, the move will affect only the assembly phase of manufacturing. The Company's 75 percent expansion of wafer fabrication capacity is unaffected by the move. The assembly lines will be moved out of the California plant over a 12 to 18 month period.
MARKETING, SALES AND DISTRIBUTION
The Company markets its products through sales personnel, representatives, or distributors. The Company believes its ability to offer products that serve each of the four functions of power conversion enhances its competitive position in the overall power semiconductor market.
In fiscal year 1995 the Company's sales by region were approximately 46% from North America, 28% from Europe, and 26% from Asia. The Company's domestic direct sales force is organized in four sales zones. In Western Europe, the Company's products are sold through its own sales force as well as through sales agents and distributors. The Company's European sales and representative offices are in England, Italy, Sweden, France, Germany, Finland, Denmark, Russia, Poland, the Czech Republic, and Hungary. In Asia IR has sales and representative liaison offices in India, Japan, Singapore, China, Hong Kong, and Korea.
Because many applications require products from several product groups, the Company has organized its marketing efforts by market sector, rather than product type. These business management groups focus on several key commercial sectors and on government and aerospace business. In addition, the Company's staff of applications engineers provides customers with technical advice and support regarding the use of IR's products.
CUSTOMERS
In most cases, the Company's devices are incorporated in larger systems manufactured by end product manufacturers. The Company's customers in the automotive segment include General Motors Corp., Ford, Delco, Siemens AG and Bosch. International Business Machines Corp., Hewlett Packard Co., Apple Computer Inc. and Compaq purchase the Company's products in the computer segment. Consumer electronics customers include Philips and Sony. Customers in the telecommunications segment include AT&T Technologies, Inc. and Nokia. The Company also sells its products to distributors including Arrow Electronics, Future Electronics, and Pioneer Electronics/Pioneer Technology.
BACKLOG
As of June 30, 1995, the Company's backlog of orders was $210.8 million compared to $121.8 million as of June 30, 1994. Backlog represents purchase orders which have been released for shipment and are scheduled to be shipped within the following 12 months. In accordance with industry practice, IR may in certain circumstances release customers from purchase orders without penalty. Increasingly, major customers are operating their businesses with shorter lead times and are placing orders on a periodic rather than an annual basis. Orders are cancelable and backlog is not necessarily indicative of sales for any future period.
RESEARCH AND DEVELOPMENT
The Company is involved in ongoing research and development directed toward new processes, devices and packages as well as continued improvement of quality and reliability in existing products.
In fiscal years 1995, 1994 and 1993, the Company spent approximately $20.1 million, $16.4 million and $14.1 million, respectively, on research and development activities. In fiscal 1994, the Company introduced a variety of products designed to address growth opportunities identified by market sector: high-density, high-efficiency HEXFETs and surface-mount packages for portable electronics; High Voltage Control ICs for lighting and motor control applications; and IGBT devices for motor controls. IR's research and development program is focused on advancing and diversifying the HEXFET product line, expanding the related IGBT products, and developing High Voltage Control ICs and other power products that work in combination with HEXFETs and IGBTs to improve system performance. IR's research and development staff also works with the marketing staff to develop new products that address specific customer needs. Efforts are directed towards developing new processes that enable the Company to produce smaller, more efficient devices. Efforts are also directed at reducing assembly costs and developing new package designs and assembly processes.
INTELLECTUAL PROPERTY
The Company has made significant investments in developing and protecting its intellectual property. Through successful enforcement of its patents, the Company has entered into a number of license agreements, generated royalty income and received substantial payments in settlement of litigation. The Company currently has 64 unexpired U.S. patents and 45 U.S. patents pending. Those patents fundamental to the Company's products expire between 2000 and 2010. In addition, the Company has 60 foreign patents and 73 foreign patents pending in a number of countries. The Company is also licensed to use certain patents owned by others. Under the terms of an agreement with Unitrode Corporation that terminates in March 2000, the Company pays Unitrode Corporation approximately 12% of the Company's net patent royalty income. The Company has several registered trademarks in the United States and abroad including trademarks for HEXFET. The Company believes that its proprietary technology and intellectual property contribute to its competitive advantage.
Since the Company believes that its power MOSFET patents are broadly applicable, it is committed to enforcing its rights under those patents and is pursuing additional license agreements. The Company presently has royalty-bearing license agreements with 13 companies: CP Clare Corporation, Harris Corporation; Hitachi, Ltd.; Matsushita Electronics Corporation; Mitsubishi Electric Corporation; National Semiconductor Corporation; NEC Corporation; Nihon Inter Electronics Corporation; Sanken Electric Company, Ltd.; SGS-Thomson Microelectronics, Inc.; Siliconix incorporated; Toshiba Corporation; and Unitrode Corporation. In fiscal 1995, $9,743,000 of revenues were derived from such royalty-bearing license agreements.
Certain of the company's fundamental power MOSFET patents have been subjected, and continue to be subjected, to reexamination in the United States Patent and Trademark Office ("PTO"). The patents subject to reexamination are fundamental to the Company's MOS transistors and their loss would allow competitors to use currently patented features of the Company's MOS transistor technology without liability for infringement of those patents. On the following dates, the PTO granted requests for reexamination of the following patents of the Company: November 13, 1992 and September 12, 1994 on patent 4,642,666; September 12, 1994 on patent 4,959,699; September 23, 1994 and June 28, 1995 on patent 5,008,725; January 17, 1995 on patent 5,130,767; June 5, 1995 on patent 5,191,396; and June 14,1995 on patent 4,593,302. On February 14, 1995, the PTO issued a reexamination certificate, confirming the patentability of the Company's U.S. patent 4,705,759.
Although no assurance can be given as to the ultimate outcome of the Company's patent enforcement efforts, the PTO reexamination proceedings, or the success of the Company's patent licensing program, the Company believes that its patent portfolio will be the source of continuing royalty income.
COMPETITION
The Company encounters differing degrees of competition for its various products, depending upon the nature of the product and the particular market served. Generally, the semiconductor industry is highly competitive, and many of the Company's competitors are larger companies with
greater financial resources than IR. The Company believes that its breadth of product line and its ability to combine products that serve the different functions into one package distinguish it from its competitors. IR's products compete with products manufactured by others based on breadth of product line, quality, price, reliability, over-all performance of the products, delivery time to the customer, and service (including technical advice and support). The Company's competitors include Eupec, Harris Corporation, Hitachi Ltd., Motorola, Inc., NEC Corporation, Philips International B.V., Powerex, Inc., Samsung Semiconductor Inc., SGS-Thomson Microelectronics, Siemens AG, Siliconix incorporated, Toshiba Corporation and Westcode Semiconductors Ltd.
ENVIRONMENTAL MATTERS
Federal, state and local laws and regulations impose various restrictions and controls on the discharge of certain materials, chemicals and gases used in semiconductor processing. The Company does not believe that compliance with such laws and regulations will have a material adverse effect on its financial position.
The Company and Rachelle Laboratories, Inc. ("Rachelle"), its former pharmaceutical subsidiary which discontinued operations in 1986, have been named among several hundred entities as potentially responsible parties ("PRPs") under the provisions of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), in connection with the United States Environmental Protection Agency's ("EPA") investigation of the disposal of allegedly hazardous substances at a major superfund site in Monterey Park, California (the "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 CERCLA. The lawsuit against the Company, relating to the first and second consent decrees, was settled in August 1993 for the sum of $40,000 to avoid protracted and expensive litigation. In June 1995, the Company was named among others as a party defendant in Federal Court apparently in connection with a third consent decree with respect to the OII Site. The Company recently received a letter (dated July 25, 1995) from the U.S. Department of Justice offering to settle claims against Rachelle relating to the first three elements of cleanup work at the OII Site for the sum of $4,953,148. (The final remedy assessment has not yet been made). The letter stated that if the offer is not accepted by September 1, 1995, enforcement action will follow. The Department of Justice letter is being evaluated. Claims have been made with the Company's insurers with respect to the OII Site matter; however, there can be no assurance that insurance coverage attaches to these claims. The Company does not believe that either it or Rachelle is responsible for the disposal at the OII Site of any material constituting hazardous substances under CERCLA. Although the ultimate resolution of this matter is unknown, the Company believes that it will not have a material adverse impact on its financial position.
In May 1993, the Company purchased property from its Employee Profit Sharing and Retirement Plan. It was determined that the property required clean-up of seepage from a storage tank, at an estimated additional cost of $525,000. The Company commenced the clean-up in fiscal year 1994, and through June 30, 1995 approximately $450,000 in clean-up costs have been incurred which will be capitalized as additional costs of the property.
On July 18, 1994, the Company received a letter from the State of Washington Department of Ecology (the "Department") notifying the Company of a proposed finding that the Company is a potentially liable person ("PLP") for alleged PCE contamination (also knows as perchloroethylene, tetrachloroethylene, and other names) of real property and groundwater in Yakima County, Washington. The letter alleges that the Company arranged for disposal or treatment of the PCE or arranged with a transporter for the disposal or treatment of the PCE in Yakima County. The Company replied by a letter dated August 11, 1994, stating that it has not contributed to PCE or other solvent contamination at the Yakima County site (resulting from sending carbon canisters for regeneration to a facility in the county) and that it should not be designated a PLP. On October 11, 1994, the Company received a letter from the Department notifying the Company of its finding that the Company is a PLP in the above matter. Initial information indicates that less than one percent of all contaminated carbon sent to the site by PLPs was contributed by the Company. What amount, if any, the Company may be asked to contribute to solve the groundwater problem is unknown.
The Company received a letter dated September 9, 1994, from the State of California Department of Toxic Substances Control stating that the Company may be a PRP for the deposit of hazardous substances at a facility in Whittier, California. The Company, in June 1995, agreed to join a group of other PRPs to remove contamination from the site. Although the final outcome is not known and depends on final clean-up costs and the allocation scheme, the group currently estimates a total clean-up cost of about $1.8 million to $2.5 million, of which about $6,000 to $9,000 might be requested to be borne by the Company.
EMPLOYEES
As of June 30, 1995, the Company employed approximately 3,310 people, of whom approximately 2,190 are employed in North America, 1,070 in Western Europe and 50 in Asia. The Company is not a party to any collective bargaining agreements. The Company considers its relations with its employees to be good.
ITEM 2.

ITEM 2. PROPERTIES
The Company's operations occupy a total of approximately 889,000 square feet, of which approximately 502,000 square feet are located within the United States. Of the worldwide total, approximately 268,000 square feet are leased and the balance is owned by the Company.
IR's leases expire between 1995 and 2012. If the Company is unable to renew these leases upon expiration, it believes that it could find other suitable premises without any material adverse impact on its operations.
The Company's major facilities are in the following locations:
The Company believes that these facilities are adequate for its current and anticipated near term operating needs. IR estimates that it currently utilizes approximately 81.4% of its worldwide manufacturing capacity. To meet rising demand for power MOSFETs, the Company is expanding wafer fabrication at HEXFET America. Planned to be in production by the end of calendar 1995, the Company believes that the estimated $75 million expansion will increase the Company's wafer capacity in power MOSFETs by about 75%.
The Company has nine sales offices located throughout the United States, and other sales and technical support offices in Canada, France, Germany, Finland, Scandinavia, Russia, Czech Republic, Hungary, Hong Kong, Japan, China, Korea, Singapore, and India which operate in leased facilities.
ITEM 3.

ITEM 3. LEGAL PROCEEDINGS
The Company and SGS-Thomson Microelectronics, Inc. ("SGS") are engaged in various legal proceedings relating to their respective power MOSFET patents. SGS filed suit against the Company in June 1991 in Federal District Court in Texas, charging infringement of U.S. patent 4,553,314. On motion by the Company, the suit was transferred to the Federal District Court in Los Angeles, California, and thereafter SGS amended its complaint to charge infringement of U.S. patents
4,495,513 and 4,712,127. SGS alleges, in substance, that the Company's power MOSFET, power IC and IGBT products infringe the '314 patent, that the Company's IGBT products infringe the '513 patent and that certain packages for the Company's products (including certain power MOSFET packages) infringe the '127 patent. The complaint, as amended, seeks unspecified actual damages (but no less than an unspecified reasonable royalty) and an injunction restraining further sales of such products. On February 1, 1993, the District Court dismissed SGS's claims for infringement of the '127 and '513 patents for lack of standing and on March 15, 1993, ruled that the SGS '314 patent is unenforceable due to inequitable conduct. SGS appealed these rulings, as well as the order transferring the case to California, to the Court of Appeals for the Federal Circuit. The Company cross-appealed a separate ruling by the District Court denying the Company's motion for summary judgment that the '314 patent is invalid. In July 1994, the Federal Circuit vacated the District Court's grants of summary judgment as to the '513, '127 and '314 patents and affirmed the District Court's denial of the Company's motion for summary judgment of invalidity of the '314 patent. The Federal Circuit ordered, however, that the case should proceed in California. A trial date of November 14, 1995 has been set for the '513 patent, but proceedings on the '314 and '127 patents are essentially stayed pending completion of reexamination of these patents in the PTO.
In separate proceedings before the same California District Court, the Company sought enforcement of a prior license agreement between the Company and SGS. The Court in July 1994, granted the Company's motions to enforce the license agreement with SGS, requiring SGS to pay additional past and prospective royalties under the Company's U.S. patents 4,959,699 and 4,642,666 on SGS's sales of power MOSFET, IGBT and power IC products. SGS appealed this decision to the Federal Circuit, which on May 10, 1995 affirmed the decision in favor of the Company. SGS subsequently made the required past royalty payment.
The Company has also filed a separate action in the same District Court against SGS and its Italian affiliate, SGS-Thomson Microelectronics, S.r.l., seeking an injunction against infringement of the Company's U.S. patents 5,008,725 and 5,130,767. This action has been essentially stayed pending completion of reexamination of these patents by the PTO.
The Company, its directors and certain officers have been named as defendants in three class action lawsuits filed in Federal Court in California. These suits seek unspecified but substantial compensatory and punitive damages for alleged intentional and negligent misrepresentations and violations of the federal securities laws. The complaints generally allege that the Company and the other defendants made materially false statements or omitted to state material facts 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. Although the Company believes that the 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 financial condition and results of operations. Two of these suits also name Kidder, Peabody & Co. Incorporated and Montgomery Securities as defendants. The Court has scheduled trial to begin in December 1995.
No provision for any liability that may result upon adjudication of these matters has been made in the consolidated financial statements.

ITEM 7.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
RESULTS OF OPERATIONS
The following table sets forth certain items included in selected financial data as a percentage of revenues.
1995 COMPARED WITH 1994
Revenues for fiscal 1995 increased 30.4% to $429.0 million from $328.9 million in the prior year. The Company's revenue increase reflected continued growing demand for the Company's power MOSFET and related devices which resulted in a 34% increase in revenues from these products. Revenues from the thyristor and rectifier product lines increased 17% from the prior period. Changes in foreign exchange rates positively impacted revenues by approximately $11.1 million. Revenues for fiscal 1995 also included $9.7 million of net patent royalties compared to $9.0 million in the prior period.
Gross profit was 35.2% of revenues ($150.8 million) in fiscal 1995 versus 33.1% of revenues ($108.9 million) in fiscal 1994. The increased margin reflected greater manufacturing volume and efficiencies and a greater contribution from new higher margin products.
In fiscal 1995, selling and administrative expense was 19.2% of revenues ($82.3 million) versus 21.0% of revenues ($69.0 million) in fiscal 1994. The decreased percentage reflects the Company's continued commitment to reducing operating expenses as a percentage of revenues.
In fiscal 1995, the Company's research and development expenditures increased $3.7 million to $20.1 million (4.7% of revenues) from $16.4 million (5.0% of revenues) in the prior period. The Company's research and development program was focused on the advancement and diversification of the HEXFET product line and expansion of the related IGBT products, the development of High Voltage Control ICs and power products that work in combination with HEXFETs and IGBTs to improve system performance.
The major components of other expense include a $1.0 million charge for the transfer of assembly operations to the Company's Mexican subsidiary, $0.3 million of severance costs, $0.3 million on the disposal of property, plant and equipment, $0.3 million of local taxes and $0.5 million in legal fees, offset by $0.3 million in foreign currency transaction gains and $1.8 million of net patent royalty revenues related to prior years.
In fiscal 1995, net interest expense decreased by $3.2 million from the prior year. The decrease was due to approximately $2.4 million in interest income earned in the current year on funds received
from a November 1994 offering of the Company's common stock and an increase of $1.7 million of interest capitalized in the current year, partially offset by increased interest expense in the first half of the year on higher average debt balances over the prior year.
1994 COMPARED WITH 1993
The Company operates on a fiscal calendar under which the twelve months ended July 3, 1994 consisted of 52 weeks compared to 53 weeks in the twelve months ended July 4, 1993.
Revenues for fiscal 1994 increased 16.7% to $328.9 million from $281.7 million in the prior year. The Company's revenue increase reflected continued growing demand for the Company's power MOSFET and related devices which resulted in a 23.4% increase in revenues from these products. Offsetting this revenue increase was a 6.2% decrease in revenues from the Company's thyristor and rectifier product lines. This downturn reflected slow starting economies in key European markets in the first half, and the pruning of these mature product lines. Changes in foreign exchange rates negatively impacted revenues by approximately $2.0 million. Revenues for fiscal 1994 also included $9.0 million of net patent royalties compared to $9.5 million in the prior period.
Gross profit was 33.1% of revenues ($108.9 million) in fiscal 1994 versus 28.1% of revenues ($79.0 million) in fiscal 1993. The increased margin reflected IR's recovery from production constraints in fiscal 1993. In addition, greater MOSFET manufacturing volume and efficiencies resulted in lower per unit product costs and enabled the Company to balance output to market demand and return to a normal mix of original equipment manufacturers, distribution and higher margin spot market business.
In the fourth quarter of fiscal 1993 the Company extended the useful lives of certain assets. This change positively impacted gross profit by approximately $2.6 million (0.8% of revenues) during fiscal 1994.
In fiscal 1994, selling and administrative expense was 21.0% of revenues ($69.0 million) versus 22.2% of revenues ($62.6 million) in fiscal 1993. The decreased percentage reflects the Company's continued commitment to reducing operating expenses as a percentage of revenues.
In fiscal 1994, the Company's research and development expenditures increased $2.3 million to $16.4 million (5.0% of revenues) from $14.1 million (5.0% of revenues) in the prior period. The Company's research and development program was focused on the advancement and diversification of the HEXFET product line and expansion of the related IGBT products, the development of Control ICs and power products that work in combination with HEXFETs and IGBTs to improve system performance. Included in 1994 research and development expenses are the costs associated with an activity started in fiscal 1994, in Japan, where efforts are directed at reducing assembly costs and developing new assembly processes.
The major components of other expense include a $0.9 million charge for the consolidation of the Company's power products operations, $0.4 million of severance costs and $0.3 million on the disposal of property, plant and equipment, offset by $0.4 million in foreign currency transaction gains.
SEASONALITY
The Company has experienced moderate seasonality in its business in recent years. On average over the past three years, the Company has reported approximately 47% of annual revenues in the first half and 53% in the second half of its fiscal year.
LIQUIDITY AND CAPITAL RESOURCES
At June 30, 1995, the Company maintained cash and cash equivalent balances of $50.8 million and $3.0 million of short term investments. In addition, the Company had established $78.5 million of domestic and foreign revolving lines of credit, against which $17.3 million had been borrowed. Based on covenant and collateral limitations, the Company had $51.7 million available for borrowing against these lines at June 30, 1995. Additionally, the Company had at its disposal $25.0 million of unused
bank term-loan facilities and $23.8 million of unused credit lines for capital equipment financing. At June 30, 1995, the Company had made purchase commitments for capital equipment of approximately $24.9 million.
During fiscal 1996 the Company plans to spend approximately $75 million on capital expenditures for the continuing expansion of its global wafer fabrication and assembly capacity. The Company intends to fund these capital expenditure and working capital requirements through cash and cash equivalents on hand, anticipated cash flow from operations, and as needed, from funds available from revolving credit, term loan and equipment financing facilities. The Company may also consider the use of funds from other external sources, including, but not limited to, public or private offerings of debt or equity.
Although the Company believes that the class action lawsuits brought against the Company and its Board of Directors (See "Legal Proceedings") are without merit, the ultimate outcome thereof cannot be presently determined. Accordingly, the Company has not made any provision for any liability, if any, that may result upon adjudication of these matters. For the possible effects of environmental matters on liquidity, see "Business -- Environmental Matters".
FOREIGN CURRENCY TRANSACTIONS
Due to the global nature of its operations, the Company is subject to the effect of international currency fluctuations. In fiscal year 1995, over 50% of the Company's revenues were derived from sales in foreign markets. In the years ended June 30, 1995, 1994 and 1993, foreign currency fluctuations did not significantly impact net income, the Company recognized net foreign currency transactions gains of $347,000, $376,000 and $129,000, respectively.
The Company may manage potential foreign currency exposure by entering into forward exchange contracts and options. These contracts are generally not speculative in nature as the resulting gains or losses generally offset any losses or gains on the underlying hedged transactions. Cash in excess of operating requirements is maintained in the United States.
INCOME TAXES
Due in part to the utilization of net operating loss carryforwards ("NOLs"), the Company's effective income tax rate in fiscal 1995 was approximately 17%. At June 30, 1995, the Company had fully utilized its NOL's for federal income tax purposes. The Company also has approximately $4.9 million of tax credits available to offset future U.S. taxes and approximately $1 million to offset future state taxes. When available tax credits are fully utilized, the Company will be subject to an estimated annual tax rate in the range of 35% to 40%.

SHORT TERM INVESTMENTS
The Company's short term investments consist of investment grade money market instruments and government securities. All of the Company's investments have original maturities of less than one year. In accordance with the criteria established by Statement of Financial Accounting Standard No. 115, "Accounting for Certain Investments in Debt and Equity Securities", all investments have been classified as "available-for-sale".

FOREIGN CURRENCY TRANSLATION
The financial position and results of operations of the Company's foreign subsidiaries are measured using the local currency as the functional currency. Foreign assets and liabilities in the consolidated balance sheet have been translated at the rate of exchange on the balance sheet date. Revenues and expenses are translated at the average exchange rate for the year. Unrealized translation adjustments do not affect the results of operations and are reported as a separate component of stockholders' equity.

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.
U.S. income taxes have not been provided on approximately $18,875,000 of undistributed earnings of foreign subsidiaries since management considers these earnings to be invested indefinitely or substantially offset by foreign tax credits.
INTERNATIONAL RECTIFIER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) EARNINGS PER SHARE
Earnings per share is computed by dividing earnings by the weighted average number of common and common stock equivalents outstanding. Stock options outstanding under stock option plans are considered common stock equivalents. Common stock equivalents for stock options of 243,056 and 112,700 were utilized in the computation of earnings per share in 1995 and 1994, respectively. No common stock equivalents for stock options were used in 1993 as the impact would have been anti-dilutive.
INTANGIBLE ASSETS
Patent costs are amortized using the straight-line method over the life of the related patent.
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 purchased with an original maturity of three months or less to be cash equivalents.

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 INSTRUMENTS
The Company operates internationally, giving rise to exposure to market risks from changes in foreign exchange rates. The Company enters into forward foreign exchange contracts and foreign
INTERNATIONAL RECTIFIER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) currency options to hedge certain foreign currency denominated receivables and payables from its foreign subsidiaries. The related gains and losses on these contracts are included in "Other income (expense)". The Company does not hold or issue financial instruments for trading purposes.

Counterparties to the transactions were large financial institutions. At June 30, 1995, the Company had approximately $11.1 million outstanding in forward foreign exchange contracts and had no outstanding foreign currency options.
RECLASSIFICATION
Certain reclassifications have been made to previously reported amounts to conform with the current year presentation.
2. LONG-TERM DEBT AND OTHER LOANS In February 1995, the Company modified its existing $25 million unsecured credit facility from Sanwa Bank California ("Sanwa Facility"). The modified facility was increased to $30 million, consisting of a $5 million revolving line of credit and a $25 million term loan facility. In March 1995, the Company increased its existing unsecured revolving line of credit with Wells Fargo Bank, N.A. ("Wells Facility") from $10 million to $25 million. In June 1995, the Company established an additional unsecured revolving line of credit of $10 million with Nationsbank of Texas, N.A. ("Nationsbank Facility"). Interest rates for loans under the Sanwa Facility and Wells Facility are at prime, or the banks cost of funds plus 1.00%, or LIBOR plus 1.00%, while the interest rates for loans under the Nationsbank Facility are at Prime or LIBOR plus 1.00% (at the Company's option). The Wells Facility and Sanwa Facility, which expire on October 31, 1996, and the Nationsbank Facility, which expires on June 14, 1996, contain the same financial covenants and ratios which affect the availability of funds, and prohibit the Company from paying cash dividends. At June 30, 1995, there were no outstanding borrowings under these three facilities.
In February 1995, as part of the modified credit facility with Sanwa Bank California, described above, the Company may draw down up to $25 million prior to December 31, 1995 on its $25 million unsecured term loan facility ("Sanwa Term Facility"). Interest rates for such loans are at prime, or LIBOR plus 1.00%, or the bank's fixed rate (at the Company's option). Principal repayments on loans under the Sanwa Term Facility are required to be made in equal quarterly installments from March 31, 1998 through December 31, 2001. This facility contains the same financial covenants and ratios as contained in the three unsecured revolving credit facilities mentioned above. At June 30, 1995, no borrowings were outstanding under this facility.
The Company also had an additional $38.5 million of revolving credit facilities at foreign locations. The interest rate on borrowings from these facilities ranged from 2.4% to 11.0% at June 30, 1995. Under the terms of the agreements, the availability of funds is impacted by various financial covenants and collateral requirements. At June 30, 1995, there was $17.3 million outstanding under these foreign credit facilities, and the weighted average interest rate was 5.9%. The weighted average interest rate for short term borrowings during fiscal year 1995 was also 5.9%.
Based on covenant and collateral limitations under the above credit facilities, the Company had $51.7 million available for borrowing at June 30, 1995.
INTERNATIONAL RECTIFIER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
2. LONG-TERM DEBT AND OTHER LOANS (CONTINUED) The following is a summary of the Company's long-term debt and other loans at June 30, 1995 and 1994 (000's):
Principal payments on long-term debt are as follows: 1997 $8,216,000; 1998 $7,901,000; 1999 $4,405,000; 2000 $2,220,000; and $1,139,000 thereafter.
In accordance with Statement of Financial Accounting Standards No. 107 "Disclosures About Fair Value of Financial Instruments," the fair values of the Company's long-term debt has been estimated based on current rates offered to the Company for debt of the same remaining maturities. The carrying amounts of the Company's loans approximate their fair values.
3. CAPITAL STOCK The Company has an employee stock purchase plan. Under this plan employees are allowed to designate between two and ten percent of their base compensation to purchase shares of the Company's common stock at 85 percent of fair market value. In November 1993, the stock purchase plan was amended to cover an additional 1,000,000 shares. During fiscal 1995 and 1994, 74,032 and 69,065 shares were purchased at an aggregate purchase price of $915,000 and $723,000, respectively. Shares authorized under this plan that remained unissued were 980,971 and 1,055,003 at June 30, 1995 and 1994, respectively.
The Company has three stock option plans, the 1979, 1984, and 1992 Plans, as amended. Under these plans, options to purchase shares of the Company's common stock are issued to key employees as well as members of the Company's Board of Directors. Options are issued at 100% of the fair value of the Company's common stock at the date of grant and become exercisable in annual installments of 20%, beginning on the first anniversary date. The 1992 plan provides for the increase in options available for grant under the plan by 1 1/2% of total common stock outstanding on January 1 of each year. On January 1, 1995, 1994 and 1993, 374,211, 304,503 and 300,061 options, respectively, were added to the plan. During fiscal year 1995, 8,150 shares expired under the 1979 and 1984 plans.

5. INCOME TAXES Effective July 1, 1993, the Company adopted the provisions of Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes" which requires recognition of deferred tax assets and liabilities for temporary differences and net operating loss ("NOL") and tax credit carryforwards. Under SFAS No. 109, deferred income taxes are established based on enacted tax rates expected to be in effect when temporary differences are scheduled to reverse and NOL and tax credit carryforwards are expected to be utilized. Adoption of SFAS No. 109 did not have a material impact on the Company's financial position or results from operations. Prior year's financial statements have not been restated.
The major components of the net deferred tax asset (liability) as of June 30, 1995 and June 30, 1994 are as follows (000's):
Income (loss) before income taxes is as follows (000's):
The provision (benefit) for income taxes consists of (000's):
INTERNATIONAL RECTIFIER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
5. INCOME TAXES (CONTINUED) Deferred taxes result primarily from temporary differences relating to depreciation, financial statement reserves, and state taxes.
The Company's effective tax rate on pretax income (loss) differs from the U.S. Federal Statutory tax rate as follows:
During fiscal 1995, the Company fully utilized its $27.3 million of U.S. federal income tax net operating loss carryovers. The estimated tax benefit during fiscal 1995 from utilization of the net operating loss carryover was $9.7 million of which $2.3 million increased capital contributed in excess of par value of shares due to the exercise of stock options.
At June 30, 1995, the Company has approximately $2.0 million, $1.7 million, and $0.2 million, respectively, of investment, research and development, and foreign tax credit carryforwards available to reduce income taxes otherwise payable, which expire from 1996 to 2010. In addition, the Company has approximately $1.0 million of alternative minimum tax credits, which can be carried over indefinitely to offset regular tax liabilities to the extent of the alternative minimum tax, and a $1.0 million state tax credit which expires in 2002.
6. PROFIT SHARING AND RETIREMENT PLANS The Company has established defined contribution plans for all eligible employees. The Profit Sharing and Retirement Plan provides for contributions by the Company in such amounts as the Board of Directors may annually determine. The Company has also established a voluntary Retirement Savings Plan (401K) to which the Company makes an annual contribution of up to $600 for each participating employee. Combined plan contributions totaled $1,027,000, $841,000, and $511,000 for fiscal years 1995, 1994, and 1993, respectively.
7. ENVIRONMENTAL MATTERS Federal, state and local laws and regulations impose various restrictions and controls on the discharge of certain materials, chemicals and gases used in semiconductor processing. The Company does not believe that compliance with such laws and regulations will have a material adverse effect on its financial position.
The Company and Rachelle Laboratories, Inc. ("Rachelle"), its former pharmaceutical subsidiary which discontinued operations in 1986, have been named among several hundred entities as potentially responsible parties ("PRPs") under the provisions of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), in connection with the United States Environmental Protection Agency's ("EPA") investigation of the disposal of allegedly hazardous substances at a major superfund site in Monterey Park, California (the "OII Site"). Certain PRPs who settled certain claims with the EPA under consent decrees filed suit in Federal Court in May 1992

The lawsuit against the Company, relating to the first and second consent decrees, was settled in August 1993 for the sum of $40,000 to avoid protracted and expensive litigation. In June 1995, the Company was named among others as a party defendant in Federal Court apparently in connection with a third consent decree with respect to the OII Site. The Company recently received a letter (dated July 25, 1995) from the U.S. Department of Justice offering to settle claims against Rachelle relating to the first three elements of cleanup work at the OII Site for the sum of $4,953,148. (The final remedy assessment has not yet been made). The letter stated that if the offer is not accepted by September 1, 1995, enforcement action will follow. The Department of Justice letter is being evaluated. Claims have been made with the Company's insurers with respect to the OII Site matter; however, there can be no assurance that insurance coverage attaches to these claims. The Company does not believe that either it or Rachelle is responsible for the disposal at the OII Site of any material constituting hazardous substances under CERCLA. Although the ultimate resolution of this matter is unknown, the Company believes that it will not have a material adverse impact on its financial position.
In May 1993, the Company purchased property from its Employee Profit Sharing and Retirement Plan. It was determined that the property required clean-up of seepage from a storage tank, at an estimated additional cost of $525,000. The Company commenced the clean-up in fiscal year 1994 and through June 30, 1995 approximately $450,000 in clean-up costs have been incurred which will be capitalized as additional costs of the property.
On July 18, 1994, the Company received a letter from the State of Washington Department of Ecology (the "Department") notifying the Company of a proposed finding that the Company is a potentially liable person ("PLP") for alleged PCE contamination (also knows as perchloroethylene, tetrachloroethylene, and other names) of real property and groundwater in Yakima County, Washington. The letter alleges that the Company arranged for disposal or treatment of the PCE or arranged with a transporter for the disposal or treatment of the PCE in Yakima County. The Company replied by a letter dated August 11, 1994, stating that it has not contributed to PCE or other solvent contamination at the Yakima County site (resulting from sending carbon canisters for regeneration to a facility in the county) and that it should not be designated a PLP. On October 11, 1994, the Company received a letter from the Department notifying the Company of its finding that the Company is a PLP in the above matter. Initial information indicates that less than one percent of all contaminated carbon sent to the site by PLPs was contributed by the Company. What amount, if any, the Company may be asked to contribute to solve the groundwater problem is unknown.
The Company received a letter dated September 9, 1994, from the State of California Department of Toxic Substances Control stating that the Company may be a PRP for the deposit of hazardous substances at a facility in Whittier, California. The Company, in June 1995, agreed to join a group of other PRPs to remove contamination from the site. Although the final outcome is not known and depends on final clean-up costs and the allocation scheme, the group currently estimates a total clean-up cost of about $1.8 million to $2.5 million, of which about $6,000 to $9,000 might be requested to be borne by the Company.

8. COMMITMENTS The future minimum lease commitments under non-cancelable capital and operating leases of equipment and real property at June 30, 1995 are as follows (000's):
Total rental expense on all operating leases charged to income was $7,965,000, $6,723,000, and $5,591,000 in fiscal years 1995, 1994 and 1993, respectively.
9. INTELLECTUAL PROPERTY RIGHTS Certain of the Company's fundamental power MOSFET patents have been subjected, and continue to be subjected, to reexamination in the United States Patent and Trademark Office ("PTO"). The patents subject to reexamination are fundamental to the Company's MOS transistors and their loss would allow competitors to use currently patented features of the Company's MOS transistor technology without liability for infringement of those patents. On the following dates, the PTO granted requests for reexamination of the following patents of the Company: November 13, 1992 and September 12, 1994 on patent 4,642,666; September 12, 1994 on patent 4,959,699; September 23, 1994 and June 28, 1995 on patent 5,008,725; January 17, 1995 on patent 5,130,767; June 5, 1995 on patent 5,191,396; and June 14, 1995 on patent 4,593,302. On February 14, 1995, the PTO issued a reexamination certificate, confirming the patentability of the Company's U.S. patent 4,705,759.
10. LITIGATION The Company and SGS-Thomson Microelectronics, Inc. ("SGS") are engaged in various legal proceedings relating to their respective power MOSFET patents. SGS filed suit against the Company in June 1991 in Federal District Court in Texas, charging infringement of U.S. patent 4,553,314. On motion by the Company, the suit was transferred to the Federal District Court in Los Angeles, California, and thereafter SGS amended its complaint to charge infringement of U.S. patents 4,495,513 and 4,712,127. SGS alleges, in substance, that the Company's power MOSFET, power IC and IGBT products infringe the '314 patent, that the Company's IGBT products infringe the '513 patent and that certain packages for the Company's products (including certain power MOSFET packages) infringe the '127 patent. The complaint, as amended, seeks unspecified actual damages (but no less than an unspecified reasonable royalty) and an injunction restraining further sales of such products. On February 1, 1993, the District Court dismissed SGS's claims for infringement of the '127 and '513 patents for lack of standing and on March 15, 1993, ruled that the SGS '314 patent is unenforceable due to inequitable conduct. SGS appealed these rulings, as well as the order transferring the case to California, to the Court of Appeals for the Federal Circuit. The Company cross-appealed a separate ruling by the District Court denying the Company's motion for summary judgment that the '314 patent is invalid. In July 1994, the Federal Circuit vacated the District Court's grants of summary judgment as to the '513, '127 and '314 patents and affirmed the District Court's denial of the Company's motion for summary judgment of invalidity of the '314 patent. The Federal
INTERNATIONAL RECTIFIER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
10. LITIGATION (CONTINUED) Circuit ordered, however, that the case should proceed in California. A trial date of November 14, 1995 has been set for the '513 patent, but proceedings on the '314 and '127 patents are essentially stayed pending completion of reexamination of these patents in the PTO.
In separate proceedings before the same California District Court, the Company sought enforcement of a prior license agreement between the Company and SGS. The Court in July 1994, granted the Company's motions to enforce the license agreement with SGS, requiring SGS to pay additional past and prospective royalties under the Company's U.S. patents 4,959,699 and 4,642,666 on SGS's sales of power MOSFET, IGBT and power IC products. SGS appealed this decision to the Federal Circuit, which on May 10, 1995 affirmed the decision in favor of the Company. SGS subsequently made the required past royalty payment.
The Company has also filed a separate action in the same District Court against SGS and its Italian affiliate, SGS-Thomson Microelectronics, S.r.l., seeking an injunction against infringement of the Company's U.S. patents 5,008,725 and 5,130,767. This action has been essentially stayed pending completion of reexamination of these patents by the PTO.
The Company, its directors and certain officers have been named as defendants in three class action lawsuits filed in Federal Court in California. These suits seek unspecified but substantial compensatory and punitive damages for alleged intentional and negligent misrepresentations and violations of the federal securities laws. The complaints generally allege that the Company and the other defendants made materially false statements or omitted to state material facts 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. Although the Company believes that the 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 financial condition and results of operations. Two of these suits also name Kidder, Peabody & Co. Incorporated and Montgomery Securities as defendants. The Court has scheduled trial to begin in December 1995.
No provision for any liability that may result upon adjudication of these matters has been made in the consolidated financial statements.
The Company is currently involved in litigation arising in the normal course of business. Management does not believe that the ultimate resolution of this litigation will have a material adverse impact on the financial position of the Company (also see Notes 7 and 9).
11. EXECUTIVE AGREEMENT The Company entered into an executive agreement with Eric Lidow dated May 15, 1991 providing for his continued employment with the Company for a six year period as Chief Executive Officer and President or in such other position as the Board of Directors may determine. Mr. Lidow's salary at fiscal year end under this agreement was $632,500. Upon Mr. Lidow's retirement from the Company (or a change in control) he will receive annual payments (Founder's Pension) of 90% of his then current salary. The agreement was amended on April 12, 1995 to provide that upon retirement Mr. Lidow's pension would be based, in addition to his salary, on the average of the prior three years' cash bonuses, if any. The pension would further be adjusted annually to account for any increase in the Consumer Price Index. Upon Mr. Lidow's death, payments will be continued to his wife, if she survives

11. EXECUTIVE AGREEMENT (CONTINUED) him, in an amount equal to two-thirds of his retirement benefits for the remainder of her life. Under the terms of the Founder's Pension, $1,068,000, $572,000, and $572,000, have been expensed in fiscal years 1995, 1994, and 1993, respectively.
