OVERVIEW Amkor is one of the world's largest subcontractors of semiconductor packaging and test services. Amkor pioneered the outsourcing of semiconductor assembly and test services in 1968, and over the years has built a leading position by: - Providing a broad portfolio of packaging and test technologies and services; - Maintaining a leading role in the design and development of new package and test technologies; - Cultivating long-standing relationships with customers, including many of the world's leading semiconductor companies; - Developing expertise in high-volume manufacturing; and - Diversifying our operational scope by providing production capabilities in China, Japan and Taiwan, in addition to long-standing capabilities in Korea and the Philippines. The semiconductors that we package and test for our customers ultimately become components in electronic systems used in communications, computing, consumer, industrial, automotive and military applications. Our customers include, among others, Atmel Corporation, Infineon Technologies AG, Intel Corporation, LSI Logic Corporation, Mediatek Inc., Philips Electronics N.V., ST Microelectronics PTE, Sony Semiconductor Corporation, Toshiba Corporation and Xilinx, Inc. The outsourced semiconductor packaging and test market is very competitive. We also compete with the internal semiconductor packaging and test capabilities of many of our customers, some of whom can use us as a source of overflow capacity. Packaging and test are an integral part of the semiconductor manufacturing process. Semiconductor manufacturing begins with silicon wafers and involves the fabrication of electronic circuitry into complex patterns, thus creating individual chips on the wafers. The packaging process creates an electrical interconnect between the semiconductor chip and the system board. In packaging, the fabricated semiconductor wafers are cut into individual chips which are attached to a substrate and then encased in a protective material to provide optimal electrical and thermal performance. The packaged chips are then tested using sophisticated equipment to ensure that each packaged chip meets its design specifications. Increasingly, packages are custom designed for specific chips and specific end-market applications. We historically marketed the output of fabricated semiconductor wafers provided by a wafer fabrication foundry owned and operated by Anam Semiconductor, Inc. (ASI). On February 28, 2003, we sold our wafer fabrication services business to ASI. We have restated our historical results to reflect our wafer fabrication services segment as a discontinued operation. Amkor was incorporated in 1997 in the state of Delaware as the successor-in-interest to various entities initially founded in 1970. References in this annual report to Amkor shall mean Amkor and, as applicable, its predecessor entities. WEBSITE ACCESS TO SEC REPORTS We maintain an Internet website at www.amkor.com.

As semiconductor devices have evolved, there have been three important consequences: (1) an increase in demand for computers and consumer electronics fostered by declining prices for such products; (2) the proliferation of semiconductor devices into diverse end products such as consumer electronics, communications equipment and automotive systems; and (3) an increase in the semiconductor content in electronic products. OUTSOURCING TRENDS Historically, semiconductor companies packaged semiconductors primarily in their own factories and relied on subcontract providers to handle overflow volume. In recent years, semiconductor companies have increasingly outsourced their packaging and testing to subcontract providers, such as us, for the following reasons: SUBCONTRACT PROVIDERS HAVE DEVELOPED EXPERTISE IN ADVANCED PACKAGING TECHNOLOGIES. Semiconductor companies are facing increasing demands for miniaturization and improved thermal and electrical performance in semiconductor devices. This trend, coupled with increasing complexity in the design of semiconductor devices, has led many semiconductor companies to view packaging as an enabling technology requiring sophisticated expertise and technological innovation. As packaging and technology becomes more advanced, many semiconductor companies have had difficulty developing adequate internal packaging capabilities and are relying on subcontract providers of packaging and test services as a key source of new package design and production. SUBCONTRACT PROVIDERS CAN OFFER SHORTER TIME TO MARKET FOR NEW PRODUCTS BECAUSE THEIR RESOURCES ARE DEDICATED TO PACKAGING AND TEST SOLUTIONS. We believe that semiconductor companies are seeking to shorten the time to market for their new products, and that having the right packaging technology and capacity in place is a critical factor in facilitating product introductions. Semiconductor companies frequently do not have sufficient time to develop their packaging and test capabilities or the equipment and expertise to implement new packaging technology in volume. For this reason, semiconductor companies are leveraging the resources and capabilities of subcontract packaging and test companies to deliver their new products to market more quickly. MANY SEMICONDUCTOR MANUFACTURERS DO NOT HAVE THE ECONOMIES OF SCALE TO OFFSET THE SIGNIFICANT COSTS OF BUILDING PACKAGING AND TEST FACTORIES. Semiconductor packaging is a complex process requiring substantial investment in specialized equipment and factories. As a result of the large capital investment required, this manufacturing equipment must operate at a high capacity level for an extended period of time to be cost effective. Shorter product life cycles, faster introductions of new products and the need to update or replace packaging equipment to accommodate new package types have made it more difficult for semiconductor companies to maintain cost effective utilization of their packaging and test assets. Subcontract providers of packaging and test services, on the other hand, can use their equipment to support a broad range of customers, potentially generating greater manufacturing economies of scale. THE AVAILABILITY OF HIGH QUALITY PACKAGING AND TESTING FROM SUBCONTRACTORS ALLOWS SEMICONDUCTOR MANUFACTURERS TO FOCUS THEIR RESOURCES ON SEMICONDUCTOR DESIGN AND WAFER FABRICATION. As semiconductor process technology migrates to larger wafers and smaller feature size, the cost of a state-of-the-art wafer fabrication facility can approach $3 billion or more. Subcontractors have demonstrated their ability to deliver advanced packaging and test solutions at a competitive price, thus allowing semiconductor companies to focus their capital resources on core wafer fabrication activities rather than invest in advanced packaging and test technology. 4

THERE ARE A GROWING NUMBER OF SEMICONDUCTOR COMPANIES WITHOUT FACTORIES, KNOWN AS "FABLESS" COMPANIES, WHICH DESIGN SEMICONDUCTOR CHIPS AND OUTSOURCE ALL OF THE ASSOCIATED MANUFACTURING. Fabless semiconductor companies focus exclusively on the semiconductor design process and outsource virtually every step of the manufacturing process. We believe that fabless semiconductor companies will continue to be a significant driver of growth in the subcontract packaging and test industry. These outsourcing trends, combined with the growth in the number of semiconductor devices being produced and sold, are increasing demand for subcontracted packaging and test services. Today, nearly all of the world's major semiconductor companies use packaging and test service subcontractors for at least a portion, if not all, of their packaging and test needs. COMPETITIVE STRENGTHS We believe our competitive strengths include the following: BROAD OFFERING OF PACKAGE DESIGN, PACKAGING AND TEST SERVICES Integrating advanced semiconductor technology into electronic end products often poses unique thermal and electrical challenges, and Amkor employs a large number of design engineers to create package formats that solve these challenges. Amkor produces more than 1,000 package types, representing one of the broadest package offerings in the semiconductor industry. We provide customers with a wide array of packaging alternatives including traditional leadframe, advanced leadframe and laminate packages, in both wirebond and flip chip formats. We are also a leading assembler of complementary metal oxide silicon ("CMOS") image sensor devices used in digital cameras and cellular phones, and micro-electromechanical system ("MEMS") devices used in a variety of end markets, including automotive, industrial and personal entertainment. We also offer an extensive line of services to test digital, logic, analog and mixed signal semiconductor devices. We believe that the breadth of our packaging and test services is important to customers seeking to reduce the number of their suppliers. LEADING TECHNOLOGY INNOVATOR We believe that we are one of the leading providers of advanced semiconductor packaging and test solutions. We have designed and developed several state-of-the-art leadframe and laminate package formats including our MicroLeadFrame(R), VisionPak(TM), PowerQuad(R), SuperBGA(R), fleXBGA(R) and ChipArray(R) BGA packages. To maintain our leading industry position, we have more than 300 employees engaged in research and development focusing on the design and development of new semiconductor packaging and test technology. We work closely with customers and technology partners to develop new and innovative package designs. LONG-STANDING RELATIONSHIPS WITH PROMINENT SEMICONDUCTOR COMPANIES Our customer base consists of more than 300 companies, including most of the world's largest semiconductor companies. Over the last three decades Amkor has developed long-standing relationships with many of our customers. ADVANCED MANUFACTURING CAPABILITIES We believe that our company's manufacturing excellence has been a key factor in our success in attracting and retaining customers. We have worked with our customers and our suppliers to develop proprietary process technologies to enhance our existing manufacturing capabilities, reduce time to market, increase quality and lower manufacturing costs. We believe our manufacturing cycle times are among the fastest available from any subcontractor of packaging and test services. COMPETITIVE DISADVANTAGES You should be aware that our competitive strengths may be diminished or eliminated due to certain challenges faced by our company and which our principal competitors may not face, including the following: 5

- High Leverage and Restrictive Covenants -- Our substantial indebtedness and the covenants contained in the agreements with our lenders could materially restrict our operations and adversely affect our financial condition. - Risks Associated with International Operations -- We depend on our factories in Korea, the Philippines, Japan, Taiwan and China. Many of our customers' operations are also located outside of the U.S. To the extent political or economic instability or military actions occur in any of these regions, our operations could be harmed. - Difficulties Integrating Acquisitions -- We face challenges as we integrate new and diverse operations and try to attract qualified employees to support our expansion plans. In addition, we and our competitors face a variety of operational and industry risks inherent to the industry in which we operate. For a complete discussion of risks associated with our business, please read "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Risk Factors that May Affect Future Operating Performance" in Item 7 of this annual report. STRATEGY To build upon our industry position and to remain a preferred subcontractor of semiconductor packaging and test services, we are pursuing the following strategies: CAPITALIZE ON OUTSOURCING TREND We believe that while the packaging and test outsourcing trend was impacted during the recent industry downturn, there remains a long-term trend towards more outsourcing on the part of semiconductor companies. We believe that many vertically integrated semiconductor companies reduced their investments in advanced packaging and test technology during the downturn and increased their reliance on outsourced packaging and test suppliers for advanced package and test requirements. We also believe that as the semiconductor content of electronic end products increases in complexity, so will the need for the advanced package and test solutions. Accordingly, we expect semiconductor companies will expand their outsourcing of advanced semiconductor packaging and test services and we intend to capitalize on this growth. We believe semiconductor companies will increasingly outsource packaging and test services to companies who can provide advanced technology and high-quality, high-volume manufacturing expertise. LEVERAGE SCALE AND SCOPE OF PACKAGING AND TEST CAPABILITIES We are committed to expanding both the scale of our operations and the scope of our packaging and test services. We believe that our scale and scope allow us to provide cost-effective solutions to our customers in the following ways: - We have the capacity to absorb large orders and accommodate quick turn-around times, - We use our size and industry position to obtain low pricing on materials and manufacturing equipment, and - We offer an exceptionally broad range of packaging and test services and can serve as a single source for many of our customers. MAINTAIN OUR TECHNOLOGY LEADERSHIP We intend to continue to develop leading-edge packaging technologies. We believe that our focus on research and product development will enable us to enter new markets early, capture market share and promote the adoption of our new package designs as industry standards. We seek to enhance our in-house research and development capabilities through the following activities: - Collaborating with integrated device manufacturer customers, or IDM customers, to gain access to technology roadmaps for next generation semiconductor designs and to develop new packages that satisfy their future requirements, 6

- Collaborating with original equipment manufacturers, or OEMs, such as Toshiba Corporation, Cisco Systems, Sony Ericsson Corporation and Nokia Group, to design new packages that function with the next generation of electronic products, and - Collaborating with wafer foundry companies on future package needs for new wafer technologies. BROADEN THE GEOGRAPHICAL SCOPE OF OUR MANUFACTURING BASE Prior to 2001, our company's manufacturing operations were centered in Korea and the Philippines. In order to diversify our operational footprint and better serve our customers, we adopted a strategy of expanding our operational base to key microelectronic manufacturing areas of Asia. During 2001, we commenced a joint venture with Toshiba Corporation in Japan and we established a manufacturing presence in Taiwan and China. Our goal is to continue to build operational scale in these new geographic locations and capitalize on growth opportunities in their respective markets. In January 2004, we purchased the remaining interest in our joint venture from Toshiba Corporation and now own 100% of the operation. PROVIDE AN INTEGRATED, TURNKEY SOLUTION We are able to provide a turnkey solution comprised of semiconductor package design, packaging, test and drop shipment services. We believe that this capability will enable customers to achieve faster time to market for new products and improved cycle times. STRENGTHEN CUSTOMER RELATIONSHIPS We intend to further develop our long-standing customer relationships. We believe that because of today's shortened technology life cycles, integrated communications are crucial to speed time to market. We have customer support personnel located near the facilities of major customers and in acknowledged technology centers. These support personnel work closely with customers to plan production for existing packages as well as to develop requirements for the next generation of packaging technology. In addition, we implement direct electronic links with our customers to enhance communication and facilitate the flow of real-time engineering data and order information. PURSUE STRATEGIC ACQUISITIONS We evaluate candidates for strategic acquisitions and joint ventures to strengthen our business and expand our geographic reach. We believe that there are many opportunities to acquire the in-house packaging operations of our customers and competitors. To the extent we acquire operations of our customers, we intend to structure any such acquisition to include long-term supply contracts with those customers. In addition, we intend to enter new markets near clusters of wafer foundries, which are large sources of demand for packaging and test services. PACKAGING AND TEST SERVICES PACKAGING SERVICES We offer a broad range of package formats designed to provide our customers with a full array of packaging solutions. Our packages are divided into two families: traditional, which includes principally traditional leadframe products, and advanced packages, which includes principally advanced leadframes and laminate products. In response to the increasing demands of today's high-performance electronic products, semiconductor packages have evolved from traditional leadframe packages and now include advanced leadframe and laminate formats. The differentiating characteristics of these package formats include (1) the size of the package, (2) the number of electrical connections the package can support, (3) the thermal and electrical characteristics of the package, and (4) in the case of our System-in-Package family of laminate packages, the integration of multiple active and passive components in a single package. As semiconductor devices increase in complexity, they often require a larger number of electrical connections. Leadframe packages are so named because they connect the electronic circuitry on the semiconductor device to the system board through leads on the perimeter of the package. Our laminate products, typically called ball grid array or BGA, use 7

balls on the bottom of the package to create the electrical connections. This array format can support larger numbers of electrical connections. Evolving semiconductor technology has allowed designers to increase the level of performance and functionality in portable and handheld electronics products, and this has led to the development of smaller package sizes. In leading-edge packages, the size of the package is reduced to approximately the size of the individual chip itself in a process known as chip scale packaging. The following table sets forth by product type, for the periods indicated, the amount of our packaging and test net revenues in millions of dollars and the percentage of such net revenues: YEAR ENDED DECEMBER 31, ------------------------------------------------------------------ 2003 2002 2001 ------------------ ----------------------- ----------------- (DOLLARS IN MILLIONS) Traditional packages........................ $ 340 21.2% $ 391 27.8% $ 439 32.8% Advanced packages........................... 1,124 70.1 915 65.1 790 59.1 Test........................................ 140 8.7 100 7.1 108 8.1 ------ ------ ------ ------ ------ ------ Total packaging and test net revenues.... $1,604 100.0% $1,406 100.0% $1,337 100.0% ====== ====== ====== ====== ====== ====== TRADITIONAL PACKAGES Traditional leadframe-based packages are the most widely used package family in the semiconductor industry and are typically characterized by a chip encapsulated in a plastic mold compound with metal leads on the perimeter. Two of the most popular traditional leadframe package types are SOIC and QFP, which support a wide variety of device types and applications. The traditional leadframe package family has evolved from "through hole design", where the leads are plugged into holes on the circuit board to "surface mount design", where the leads are soldered to the surface of the circuit board. We offer a wide range of lead counts and body sizes to satisfy variations in the size of customers' semiconductor devices. ADVANCED PACKAGES ADVANCED LEADFRAME PACKAGES Through a process of continuous engineering and customization, we have designed several advanced leadframe package types that are thinner and smaller than traditional leadframe packages, with the ability to accommodate more leads on the perimeter of the package. These advanced leadframe packages typically have superior thermal and electrical characteristics, which allow them to dissipate heat generated by high-powered semiconductor devices while providing enhanced electrical connectivity. We plan to continue to develop increasingly smaller versions of these packages to keep pace with continually shrinking semiconductor device sizes and demand for miniaturization of portable electronic products. One of our most successful advanced leadframe package offerings is the MicroLeadFrame(R) family of QFN, or Quad Flat No-lead packages. This package family is particularly well suited for radio frequency ("RF") and wireless applications. Our smallest MicroLeadFrame(R) package design is less than 2mm square and can fit on the head of a pin. LAMINATE PACKAGES The laminate family employs the ball grid array design, which utilizes a plastic or tape laminate substrate rather than a leadframe substrate and places the electrical connections on the bottom of the package rather than around the perimeter. The ball grid array format was developed to address the need for higher lead counts required by advanced semiconductor devices. As the number of leads on leadframe packages increased, leads were placed closer to one another in order to maintain the size of the package. The increased lead density resulted in electrical shorting problems, and required the development of increasingly sophisticated and expensive techniques for producing circuit boards to accommodate the high number of leads. 8

The ball grid array format solved this problem by effectively creating leads on the bottom of the package in the form of small bumps or balls that can be evenly distributed across the entire bottom surface of the package, allowing greater distance between the individual leads. Our first package format in this family was the plastic ball grid array (PBGA). We have subsequently designed or licensed additional ball grid array package formats that have superior performance characteristics and features that enable low-cost, high-volume manufacturing. These laminate products include: - SuperBGA(R), which includes a copper layer to dissipate heat and is designed for low-profile, high-power applications, and - TEPBGA-2, which is a standard PBGA with thicker copper layers plus an integrated heat slug and is designed for enhanced thermal performance in high power applications. We have also designed a variety of packages, commonly referred to as chip scale packages, or CSP, which are not much larger than the chip itself. Chip scale packages are becoming widely adopted as designers and manufacturers of consumer electronics seek to achieve higher levels of performance while shrinking the product size. Some of our chip scale packages include: - ChipArray(R)BGA and TapeArray(TM)BGA, in which the package is only 1.5 mm larger than the chip itself, and - Wafer Level Package, which further reduces package size and increases manufacturing efficiency. Advances in packaging technology now allow the placing of two or more chips on top of each other within an individual package. This concept, known as stacked packaging, permits a higher level of semiconductor density and more functionality. In addition, advance wafer thinning technology has fostered the creation of extremely thin packages that can be placed on top of each other within standard height restrictions used in microelectronic system boards. Some of our stacked packages include: - Stacked CSP (S-CSP), which is similar to our ChipArray(R) BGA, except that S-CSP contains two or more chips placed on top of each other, and - ETCSP(R), which are extremely thin chip scale packages that can be stacked on top of each other. OTHER ADVANCED PACKAGES To capitalize on an increasing customer demand for higher levels of system integration, we created our "System-in-Package" (SiP) modules. SiP modules integrate various system elements into a single-function block, thus enabling space and power efficiency, high performance and lower production costs. Most of our SiP packages are laminate based. Our SiP technology is being used to produce a variety of devices including power amplifiers for cellular phones and other portable communication devices, wireless local area network (WLAN) modules for networking applications, memory cards and sensors, such as fingerprint recognition devices. In order to accommodate the emerging use of digital imaging in a variety of consumer products, we developed VisionPak(TM), a family of CMOS image sensor-based packages that can be incorporated in such products as cellular phones, PDAs, digital cameras and PCs. We are also a leading outsourced provider of packages based on MEMS that are used in a broad range of industrial and consumer applications, including automobiles and home entertainment. TEST SERVICES Amkor provides a complete range of test solutions including wafer probe, final test, strip test, marking, bake, drypack, and tape and reel. The devices we test encompass nearly all technologies produced in the industry today including digital, linear, mixed signal, memory, RF and integrated combinations of these technologies. In 2003, Amkor tested over 1.5 billion 9

units making Amkor one of the highest volume testing companies in the subcontract packaging and test business. We tested 28%, 21% and 16% of the units that we packaged in 2003, 2002 and 2001, respectively. Our test operations are geographically located with our packaging operations to improve cycle time and facilitate information flow between the various manufacturing operations and with our customers. We are also an industry leader in providing innovative testing solutions that help to lower the total cost of test for our customers. Two examples of these innovative approaches are strip test and low cost RF test. Strip test involves parallel testing, in which large numbers of packaged units can be tested at one time, as compared to "singulated" testing in which individual packaged units are tested. With strip test, electronically isolated packaged units are tested in parallel, resulting in fast handler index times and high throughput rates, thus reducing test cost and increasing test yield. In 2003 we strip tested approximately 300 million units, bringing the total devices strip tested by us to over 500 million units since inception of the program in 1999. In the area of low cost RF test, we have developed one of the lowest cost test solutions in the industry for testing simple RF devices that are pervasive in today's cell phones and WLAN products. This test approach combines inexpensive test hardware with integration software to achieve test costs that are significantly less costly than industry standard test practices. We believe that our low cost RF test technology provides a competitive advantage for us and, when it is combined with our System in Package and MicroLeadFrame(R) packaging technologies, offers our customers one of the industry's lowest total cost solutions. Amkor also provides value added engineering services in addition to basic device testing. These services include test program development, test hardware development, test program conversion to lower cost test systems, device characterization and reliability qualification testing. In total, we can provide all of the test engineering services needed by our customers to get their products ready for high volume production. We believe that this service will continue to become more valuable to our customers as they face resource constraints not only in their production testing, but also in their test engineering and development areas. In 2003, we strengthened our test operations in Taiwan and mainland China by entering into strategic alliances in each of these countries. We entered into these alliances in order to enhance our ability to provide test support for our growing packaging business and to provide our customers broader and more rapidly scalable test capacity. WAFER FABRICATION SERVICES In January 1998, we entered into a supply agreement with ASI to market wafer fabrication services provided by ASI's semiconductor wafer fabrication facility using 0.35 micron, 0.25 micron and 0.18 micron CMOS process technology provided by Texas Instruments pursuant to technology assistance agreements with ASI. On February 28, 2003, we sold our wafer fabrication services business to ASI. Additionally, we obtained a release from Texas Instruments regarding our contractual obligations with respect to wafer fabrication services to be performed subsequent to the transfer of the business to ASI. We have restated our historical results to reflect our wafer fabrication services segment as a discontinued operation. In connection with the disposition of our wafer fabrication business, we recorded, in the first quarter of 2003, $1.0 million in severance and other exit costs to close our wafer fabrication services operations in Boise, Idaho and Lyon, France. Also in the first quarter of 2003, we recognized a pre-tax gain on the disposition of our wafer fabrication services business of $58.6 million ($51.5 million, net of tax). The carrying value of the sold net assets associated with the business as of February 28, 2003 was $2.4 million. RESEARCH AND DEVELOPMENT Our research and development efforts focus on developing new package products and improving the efficiency and capabilities of our existing production processes. We believe that technology development is one of the key success factors in the semiconductor packaging and test market and also believe that we have a distinct advantage in this area. Our focus on research and development efforts enable us to enter markets early, capture market share and promote the adoption of our new package offerings as industry standards. These efforts also support our customers' needs for smaller packages, increased performance, and lower cost. In addition, we license our leading edge technology, such as MicroLeadFrame(R), to customers and competitors. We continue to invest our research and development resources to further the development of flip chip interconnection solutions, chip scale packages, MEMS devices and System-in-Package technology. 10

As of December 31, 2003, we had more than 300 employees in research and development activities. In addition, we involve management and operations personnel in research and development activities. In 2003, 2002 and 2001, we spent $25.8 million, $31.2 million and $38.8 million, respectively, on research and development. We currently expect to increase our investment in research and development in 2004 by 40% over 2003 spending levels. MARKETING AND SALES Our marketing offices manage and promote our packaging and test services while key customer and technical support is provided through our network of international sales offices. To better serve our customers, our offices are located near our largest customers or areas where there is customer concentration. Our marketing and sales office locations include sites in the U.S. (Chandler, Arizona; Irvine, Santa Clara and San Diego, California; Boston, Massachusetts; Greensboro, North Carolina; West Chester, Pennsylvania, and Austin and Dallas, Texas), Cayman Islands, China, France, Japan, Korea, the Philippines, Singapore, Taiwan and the United Kingdom. To provide comprehensive sales and customer service, we assign each of our customers a direct support team consisting of an account manager, technical program manager, test program manager and both field and factory customer support representatives. We also support our largest multinational customers from multiple office locations to ensure that we are aligned with their global operational and business requirements. Our direct support teams are further supported by an extended staff of product, process, quality and reliability engineers, as well as marketing and advertising specialists, information systems technicians and factory personnel.

Standard Microsystems Microchip Technology Inc. Texas Instruments, Inc. Micronas Semiconductor Holding AG Toshiba Corporation Mitsubishi Electric Semiconductor Xilinx, Inc. Our services are available internationally. A summary of our domestic and international net revenue and net property, plant and equipment is set forth in Note 22 to the Consolidated Financial Statements in Item 8, which is incorporated herein by reference. More than half of our overall net revenue comes from outside of the United States. For a discussion of risks attendant to our foreign operations, see "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Risk Factors That May Affect Future Operating Performance -- Risks Associated with International Operations -- We Depend on Our Factories in the Philippines, Korea, Japan, Taiwan and China. Many of Our Customers' and Vendors' Operations Are Also Located Outside of the U.S." With the commencement of operations of Amkor Iwate and the acquisition of a packaging and test facility from Toshiba in 2001, total net revenues derived from Toshiba accounted for 11.6%, 14.7% and 16.3% of our consolidated net revenues for 2003, 2002 and 2001, respectively. Prior to the sale of our wafer fabrication services business to ASI in February 2003, we derived substantially all of our wafer fabrication revenues from Texas Instruments (TI), which due to our restatement, are no longer included in net revenues, but rather, as part of discontinued operations in the restated Consolidated Statements of Operations. MATERIALS AND EQUIPMENT Our packaging operations depend upon obtaining adequate supplies of materials and equipment on a timely basis. The principal materials used in our packaging process are leadframes or laminate substrates, gold wire and mold compound. We purchase materials based on customer forecasts, and our customers are generally responsible for any unused materials which we purchased based on such forecasts. 12

We work closely with our primary material suppliers to insure that materials are available and delivered on time. Moreover, we also negotiate worldwide pricing agreements with our major suppliers to take advantage of the scale of our operations. We are not dependent on any one supplier for a substantial portion of our material requirements. Our packaging operations depend on obtaining adequate supplies of manufacturing equipment on a timely basis. We work closely with major equipment suppliers to insure that equipment is delivered on time and that the equipment meets our stringent performance specifications. For a discussion of additional risks associated with our materials and equipment suppliers, see "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Risk Factors that May Affect Future Operating Performance" in Item 7 of this annual report. ENVIRONMENTAL MATTERS The semiconductor packaging process uses chemicals and gases and generates byproducts that are subject to extensive governmental regulations. For example, at our foreign manufacturing facilities, we produce liquid waste when silicon wafers are diced into chips with the aid of diamond saws, then cooled with running water. Federal, state and local regulations in the United States, as well as environmental regulations internationally, impose various controls on the storage, handling, discharge and disposal of chemicals used in our manufacturing processes and on the factories we occupy. We have been engaged in a continuing program to assure compliance with federal, state and local environmental laws and regulations. We do not expect capital expenditures or other costs attributable to compliance with environmental laws and regulations to have a material adverse effect on our business, results of operations or financial condition. For a discussion of additional risks associated with the environmental issues, see "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Risk Factors that May Affect Future Operating Performance -- Environmental Regulations" in Item 7 of this annual report. COMPETITION The subcontracted semiconductor packaging and test market is very competitive. We face substantial competition from established packaging and test service providers primarily located in Asia, including companies with significant manufacturing capacity, financial resources, research and development operations, marketing and other capabilities. These companies include Advanced Semiconductor Engineering, Inc., ASE Test Limited, ASAT Ltd., ChipPAC Incorporated, Orient Semiconductor Engineering, ST Assembly and Test Services and Siliconware Precision Industries Co., Ltd. Such companies have also established relationships with many large semiconductor companies that are current or potential customers of our company. We also compete with the internal semiconductor packaging and test capabilities of many of our customers. The principal elements of competition in the subcontracted semiconductor packaging market include: (1) breadth of package offering, (2) technical competence, (3) new package design and implementation, (4) quality, (5) manufacturing cycle times, (6) customer service and (7) price. We believe that we generally compete favorably with respect to each of these factors. INTELLECTUAL PROPERTY ACQUISITION OF INTELLECTUAL PROPERTY RIGHTS We maintain an active program to protect our investment in technology by acquiring intellectual property protection and enforcing our intellectual property rights. Intellectual property rights that apply to our various products and services include patents, copyrights, trade secrets and trademarks. We have filed and obtained a number of patents in the United States and abroad. While our patents are an important element of our intellectual property strategy and our success, as a whole we are not materially dependent on any one patent or any one technology. We expect to continue to file patent applications when appropriate to protect our proprietary technologies, but we cannot assure you that we will receive patents from pending or future applications. In addition, any patents we obtain may be challenged, invalidated or circumvented and may not provide meaningful protection or other commercial advantage to us. 13

We also protect certain details about our processes, products and strategies as trade secrets, keeping confidential the information that we believe provides us with a competitive advantage. We have ongoing programs designed to maintain the confidentiality of such information. Further, to distinguish our products from our competitors' products, we have obtained certain trademarks and trade names. We have promoted and will continue to promote our particular product brands through advertising and other marketing techniques. ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS We may need to enforce our patents or other intellectual property rights or defend ourselves against claimed infringement of the rights of others through litigation, which could result in substantial cost and diversion of our resources. We intend to license our intellectual property when it makes economic sense for us to do so, consistent with the licensing policies of the various domestic and international standards setting organizations of which we are a member. The semiconductor industry is characterized by frequent claims regarding patent and other intellectual property rights. If any third party makes an enforceable infringement claim against us, we could be required to: - discontinue the use of certain processes, - cease the manufacture, use, import and sale of infringing products, - pay substantial damages, - develop non-infringing technologies, or - acquire licenses to the technology we had allegedly infringed. If we fail to obtain necessary licenses or if we are subjected to litigation relating to patent infringement or other intellectual property matters, our business could suffer. EMPLOYEES As of December 31, 2003, we had 20,261 full-time employees including 742 employees seconded from Toshiba whose employment was transferred to Amkor as of January 1, 2004. Of the total employee population, 15,349 were engaged in manufacturing, 3,172 were engaged in manufacturing support, 344 were engaged in research and development, 427 were engaged in marketing and sales and 969 were engaged in finance, business management and administration. We believe that our relations with our employees are good. We have never experienced a work stoppage in any of our factories. Our employees in the U.S., the Philippines, Taiwan and China are not represented by a collective bargaining unit. Certain members of our factories in Korea and Japan are members of a union, and all employees at these factories are subject to collective bargaining agreements. ITEM 2. PROPERTIES We provide packaging and test services through our factories in Korea, Philippines, Japan, Taiwan and China. We believe that total quality management is a vital component of our advanced manufacturing capabilities. We have established a comprehensive quality operating system designed to: (1) promote continuous improvements in our products and (2) maximize manufacturing yields at high volume production without sacrificing the highest quality standards. The majority of our factories are ISO9001, ISO9002, ISO14001, QS9000 and SAC Level I certified. Additionally, as we acquire or construct additional factories, we commence the quality certification process to meet the certification standards of our existing facilities. We believe that many of our customers prefer to purchase from quality certified suppliers. In addition to providing world-class manufacturing services, our factories in the Philippines and Korea provide purchasing, engineering and customer service support. The size, location, and manufacturing services provided by each of our company's factories are set forth in the table below as of February 27, 2004. 14

Beginning July 1, 2003, these entities have been consolidated within the financial statements of Amkor, in accordance with FASB Interpretation No. 46. We own the buildings at our P1, P3 and P4 facilities and lease the buildings at our P2 facility from one of the aforementioned realty companies. (2) Property acquired in February 2004 (subject to pending regulatory approvals). (3) Leased facility. We believe that our existing properties are in good condition and suitable for the conduct of our business. At the end of fiscal 2003, we were productively utilizing the majority of the space in our facilities. We intend to expand our production capacity in 2004 and beyond as necessary to meet customer demand. We completed the closing of the K2 facility in Bucheon, South Korea during 2003. We transferred most of its packaging operations into our K4 factory in Kwangju, South Korea. Our operational headquarters is located in Chandler, Arizona, and our administrative headquarters, which is leased, is located in West Chester, Pennsylvania. In addition to executive staff, the Chandler, Arizona campus houses sales and customer service for the southwest region and product management, planning and marketing. The West Chester location houses finance and accounting, legal, and information systems, and serves as a satellite sales office for our eastern sales region. Our marketing and sales office locations include sites in the U.S. (Chandler, Arizona; Irvine, Santa Clara and San Diego, California; Boston, Massachusetts; Greensboro, North Carolina; West Chester, Pennsylvania, and Austin and Dallas, Texas), Cayman Islands, China, France, Japan, Korea, the Philippines, Singapore, Taiwan and the United Kingdom. 15

ITEM 3. LEGAL PROCEEDINGS We are currently a party to various legal proceedings, including those noted below. While we currently believe that the ultimate outcome of these proceedings, individually and in the aggregate, will not have a material adverse effect on our financial position or overall trends in results of operations, litigation is subject to inherent uncertainties. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on our net income in the period in which the ruling occurs. The estimate of the potential impact from the following legal proceedings on our financial position or overall results of operations could change in the future. EPOXY MOLD COMPOUND LITIGATION Recently, we have become party to an increased number of litigation matters relative to our historic levels. Much of our recent increase in litigation relates to an allegedly defective epoxy mold compound, formerly used in some of our products, which is alleged to be responsible for certain semiconductor chip failures. In the case of each of these matters, we believe we have meritorious defenses, as well as valid third-party claims against Sumitomo Bakelite Co., Ltd. ("Sumitomo Bakelite"), the manufacturer of the challenged epoxy product, should the epoxy mold compound be found to be defective. We cannot be certain, however, that we will be able to recover any amount from Sumitomo Bakelite if we are held liable in these matters, or that any adverse result would not have a material impact upon us. Moreover, other customers of ours have made inquiries about the epoxy mold compound, which was widely used in the semiconductor industry, and no assurance can be given that claims similar to those already asserted will not be made against us by other customers in the future. Fujitsu Limited v. Cirrus Logic, Inc., et al. On April 16, 2002, we were served with a third-party complaint in an action entitled Fujitsu Limited v. Cirrus Logic, Inc., No. 02-CV-01627 JW, pending in the United States District Court for the Northern District of California, San Jose Division. In this action, Fujitsu Limited ("Fujitsu") alleges that semiconductor devices it purchased from Cirrus Logic, Inc. ("Cirrus Logic") are defective in that a certain epoxy mold compound used in the manufacture of the chip causes a short circuit which renders Fujitsu disk drive products inoperable. Cirrus Logic, in response, denied the allegations of the complaint, counterclaimed against Fujitsu for unpaid invoices, and filed its third-party complaint against us alleging that any liability for chip defects should be assigned to us because we assembled the subject semiconductor devices. Upon receipt of Cirrus Logic's third-party complaint, we filed an answer denying all liability, and our own third-party complaint against Sumitomo Bakelite. Sumitomo Bakelite filed an answer denying liability. In June 2003, Fujitsu amended its complaint and added direct claims against us. In response, we filed an answer denying all liability to Fujitsu. Fujitsu has indicated that it may seek damages in excess of $100 million. Discovery is ongoing and a trial is currently scheduled to begin in the Northern District Court of California on January 31, 2005. In November 2003, Fujitsu filed an action against Cirrus Logic, Sumitomo Bakelite and us entitled Fujitsu Limited v. Cirrus Logic, Inc., et al., No. 1-03-CV-009885, in the California Superior Court for the County of Santa Clara, based on facts and allegations substantially similar to those asserted in the Northern District Court of California. In December 2003, Cirrus Logic filed a cross-complaint against Sumitomo Bakelite and us in the Superior Court case, also based on facts and allegations substantially similar to those asserted in the Northern District Court case. By stipulation among the parties, Fujitsu and Cirrus Logic have stated their intent to stay the action pending in the Northern District Court of California in favor of the action pending in the Santa Clara Superior Court. Trial in the Superior Court action is currently scheduled to begin on January 31, 2005. Amkor intends to deny all liability, to file cross-claims against Sumitomo Bakelite, and to seek dismissal of all claims against it in due course. Seagate Technology LLC v. Atmel Corporation, et al. In March 2003, we were served with a cross-complaint in an action between Seagate Technology LLC ("Seagate") and Atmel Corporation ("Atmel") in the Superior Court of California, Santa Clara County. Atmel's cross-complaint seeks indemnification from us for any damages incurred from the claims by Seagate involving the allegedly defective epoxy mold compound manufactured by Sumitomo Bakelite. We have answered Atmel's cross-complaint, denying all liability, and have filed a cross-complaint against Sumitomo Bakelite. Atmel later amended its cross-complaint, including adding ChipPAC Inc. ("ChipPAC") as a cross-defendant. ChipPAC filed a cross-complaint against Sumitomo Bakelite and us. On January 27, 2004, the Superior Court sustained Sumitomo Bakelite's motion to dismiss Atmel's cross-complaint, granting Atmel 30 days to file an amended pleading. We filed a motion to dismiss ChipPAC's cross-complaint on February 13, 2004, and otherwise intend to deny all liability to ChipPAC. We also intend to deny all liability to Atmel and may seek the dismissal of Atmel's 16

further amended cross-complaint upon receipt, if appropriate. All parties are currently conducting discovery and no trial date has been set. Maxtor Corporation v. Koninklijke Philips Electronics N.V., et al. In April 2003, we were served with a cross-complaint in an action between Maxtor Corporation ("Maxtor") and Koninklijke Philips Electronics ("Philips"). Philips' cross-complaint seeks indemnification from us for any damages incurred from the claims by Maxtor involving the allegedly defective epoxy mold compound manufactured by Sumitomo Bakelite. Philips subsequently filed a cross-complaint directly against Sumitomo Bakelite, alleging, among other things, that Sumitomo Bakelite breached its contractual obligations to both us and Philips by supplying a defective mold compound resulting in the failure of certain Philips semiconductor devices. We have denied all liability in this matter and have also asserted a cross-complaint against Sumitomo Bakelite. Sumitomo Bakelite has denied any liability. The parties' discovery efforts are ongoing, including expert discovery. In December 2003, we filed a motion for summary judgment against Philips's cross-claims. The motion shall be heard March 30, 2004. The trial is scheduled to start on April 12, 2004. Maxim Integrated Products, Inc. v. Amkor Technology, Inc., et al. In August 2003, we were served with a complaint filed by Maxim Integrated Products, Inc. ("Maxim") against us, Sumitomo Bakelite and Sumitomo Plastics America, Inc. ("Sumitomo Plastics") in the Superior Court of California, Santa Clara County. The complaint seeks damages related to our use of Sumitomo Bakelite's epoxy mold compound in assembling Maxim's semiconductor packages. Both the Sumitomo defendants and we filed motions to dismiss Maxim's complaint in September 2003. In lieu of contesting those motions to dismiss, Maxim has indicated its intent to file an amended pleading. We intend to deny all liability to Maxim and to file cross-claims against Sumitomo Bakelite; we may file another motion to dismiss Maxim's amended complaint upon receipt, if appropriate. Discovery has not commenced and there is no trial date set. Fairchild Semiconductor Corporation v. Sumitomo Bakelite Singapore Pte. Ltd., et al. In September 2003, we were served with an amended complaint filed by Fairchild Semiconductor Corporation ("Fairchild") against us, Sumitomo Bakelite, Sumitomo Plastics and Sumitomo Bakelite Singapore Pte. Ltd. in the Superior Court of California, Santa Clara County. The amended complaint seeks damages related to our use of Sumitomo Bakelite's epoxy mold compound in assembling Fairchild's semiconductor packages. Both the Sumitomo defendants and we filed motions to dismiss Fairchild's amended complaint in October 2003. Fairchild filed a second amended complaint in January 2004. On February 11, 2004, we filed a motion to dismiss Fairchild's second amended complaint. We also intend to deny all liability and to file cross-claims against Sumitomo Bakelite. Discovery is ongoing and no trial date has been scheduled. OTHER LITIGATION Amkor Technology, Inc. v. Motorola, Inc. On August 16, 2002, we filed a complaint against Motorola, Inc. in an action captioned Amkor Technology, Inc. v. Motorola, Inc., C.A. No. 02C-08-160 CHT, pending in the Superior Court of the State of Delaware in and for New Castle County. In this action, we were seeking declaratory judgment relating to a controversy between us and Motorola concerning: (i) the assignment by Citizen Watch Co., Ltd. ("Citizen") to us of a Patent License Agreement dated January 25, 1996 between Motorola and Citizen (the "License Agreement") and concurrent assignment by Citizen to us of Citizen's interest in U.S. Patents 5,241,133 and 5,216,278 (the "'133 and '278 patents"); and (ii) our obligation to make certain payments pursuant to an immunity agreement (the "Immunity Agreement") dated June 30, 1993 between us and Motorola. We and Motorola resolved the controversy with respect to all issues relating to the Immunity Agreement, and all claims and counterclaims filed by the parties in the case relating to the Immunity Agreement were dismissed or otherwise disposed of without further litigation. The claims relating to the License Agreement and the '133 and '278 Patents remained pending. We and Motorola both filed motions for summary judgment on the remaining claims, and oral arguments were heard on September 3, 2003. On October 6, 2003, the Superior Court of Delaware ruled in favor of us and issued an Opinion and Order granting our motion for summary judgment and denying Motorola's motion for summary judgment. On October 22, 2003, Motorola filed an appeal in Supreme Court of Delaware. We believe we will prevail on the same merits in such 17

appeal. In addition, should Motorola prevail at the appellate level, we believe we have recourse against Citizen. However, no assurance can be given that an adverse outcome in the case cannot occur, or that any adverse outcome would not have a material impact. Amkor Technology, Inc. v. Carsem (M) Sdn Bhd, Carsem Semiconductor Sdn Bhd, and Carsem Inc. In November 2003, we filed complaints against Carsem (M) Sdn Bhd, Carsem Semiconductor Sdn Bhd, and Carsem Inc. (collectively "Carsem") with the International Trade Commission ("ITC") in Washington, D.C. and subsequently in the Northern District of California. The complaints allege infringement of our United States Patent Nos. 6,433,277, 6,455,356, and 6,630,728 (collectively the "Amkor Patents"). We allege that by making, using, selling, offering for sale, or importing into the U.S. the Carsem Dual and Quad Flat No-Lead Package, Carsem has infringed on one or more of our MicroLeadFrame(R) packaging technology claims in the Amkor Patents. The District Court action has been stayed pending resolution of the ITC case. The ITC action is scheduled for trial in June 2004. Alcatel Business Systems vs. Amkor Technology, Inc., Anam Semiconductor, Inc. On November 5, 1999, we agreed to sell certain semiconductor parts to Alcatel Microelectronics, N.V. ("AME"), a subsidiary of Alcatel S.A. The parts were manufactured for us by Anam Semiconductor, Inc. ("ASI"). AME transferred the parts to another Alcatel subsidiary, Alcatel Business Systems ("ABS"), which incorporated the parts into cellular phone products. In early 2001, a dispute arose as to whether the parts sold by us were defective. On March 18, 2002, ABS and its insurer filed suit against us and ASI in the Paris Commercial Court of France, claiming damages of 50 million Euros (approximately $62.8 million based on the spot exchange rate at December 31, 2003). We have denied all liability and intend to vigorously defend ourselves. Additionally, we have entered into a written agreement with ASI whereby ASI has agreed to indemnify us fully against any and all loss related to the claims of AME, ABS and ABS' insurer. The Paris Commercial Court commenced a special proceeding before a technical expert to report on the facts of the dispute. The report of the court-appointed expert was put forth on December 31, 2003. The report does not specifically allocate liability to any particular party. The next proceeding in this matter is expected in April 2004. At that time, it will be determined if jurisdiction over this case is permissible in the Paris Court. If jurisdiction is found not to be permissible, the case will be dismissed. Otherwise, the case will proceed to hearing. In response to the lawsuit, on May 22, 2002, we filed a petition to compel arbitration in the United States District Court for the Eastern District of Pennsylvania (the "Court") against ABS, AME and ABS' insurer, claiming that the dispute is subject to the arbitration clause of the November 5, 1999 agreement between us and AME. ABS and ABS' insurer have refused to arbitrate. In August 2003, the Court denied the motion of ABS and its insurer to dismiss our petition for arbitration. The Court also subsequently denied a motion for reconsideration filed by ABS. The Court has not yet set a date for final disposition of our petition. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS There were no matters submitted to a vote of security holders during the fourth fiscal quarter of the fiscal year ended December 31, 2003. 18

PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS Our common stock is traded on the Nasdaq National Market under the symbol "AMKR." Public trading of the common stock began on May 1, 1998. Prior to that, there was no public market for our common stock. The following table sets forth, for the periods indicated, the high and low sale price per share of our common stock as quoted on the Nasdaq National Market. High Low ------ ------ 2003 First Quarter........................ $ 6.44 $ 4.13 Second Quarter....................... 13.19 5.35 Third Quarter........................ 18.50 13.47 Fourth Quarter....................... 21.40 14.72 2002 First Quarter........................ $22.31 $13.00 Second Quarter....................... 24.25 3.90 Third Quarter........................ 6.10 1.20 Fourth Quarter....................... 7.47 1.61 There were approximately 236 holders of record of our common stock as of February 27, 2004. DIVIDEND POLICY Since our public offering in 1998, we have never paid a dividend to our stockholders. We currently expect to retain future earnings, if any, for use in the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. In addition, our secured bank debt agreements and the indentures governing our senior, senior subordinated and convertible subordinated notes restrict our ability to pay dividends. RECENT SALES OF UNREGISTERED SECURITIES On May 8, 2003, we sold, at an aggregate offering price, $425.0 million of 7.75% senior notes. The underwriters involved with this transaction were Citigroup Global Markets Inc., Deutsche Bank Securities and J.P. Morgan Securities Inc. The aggregate underwriting discount was 1.875%, or $8.0 million, other related transaction fees were $0.7 million and the final net proceeds to us were $416.3 million. These notes mature on May 15, 2013 and have an annual coupon rate of 7.75%. The issue price of the notes was 100%. With the proceeds from this sale, together with cash on hand, we redeemed all of our outstanding 9.25% senior notes due 2006 on June 7, 2003. The price of this redemption was 104.625% of the principal amount then outstanding, together with accrued and unpaid interest, in accordance with the indenture governing the 9.25% senior notes due 2006. The aggregate redemption price was $448.6 million, including $19.7 million of redemption premium and $3.9 million of accrued interest. The 7.75% senior notes were sold to qualified institutional buyers in reliance on Rule 144A and outside the United States in compliance with Regulation S under the Securities Act of 1933. The 7.75% senior notes were not registered under the Securities Act of 1933, as amended, and could not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. In connection with the May 8, 2003 offering of the $425.0 million of 7.75% senior notes due 2013 ("original notes"), we entered into a registration rights agreement with the initial purchasers of the original notes in which we agreed to commence an exchange offer for the original notes. In the exchange offer, the original note holders were entitled to exchange their original notes for exchange notes ("exchange notes"), with substantially identical terms as the original notes. The terms of the exchange notes are identical in all material respects to those of the original notes except the exchange notes will not be subject to transfer restrictions and holders of the exchange notes, with limited exceptions, will have no registration rights. On July 10, 2003, we filed a Form S-4 Registration Statement with the Securities and Exchange Commission, which became effective October 22, 2003, to effect this exchange offer. 19

USE OF PROCEEDS FROM REGISTERED SECURITIES On November 5, 2003, we offered 7,000,000 shares of our common stock priced at $19.00 per share. The aggregate offering price for the 7,000,000 shares was $133.0 million. We also granted to the underwriters an option to purchase 1,050,000 additional shares to cover over-allotments. The transaction was underwritten through an underwriting syndicate comprised of Citigroup Global Markets Inc., Deutsche Bank Securities, J.P. Morgan Securities Inc. and Bear, Stearns & Co. Inc. In total, 7,375,000 shares were sold, including 375,000 over-allotment shares, for aggregate proceeds of $140.1 million. The aggregate underwriting discount was 4.5%, or $6.3 million, other related transaction fees were $0.3 million and the final net proceeds to us were $133.5 million. These net proceeds were used to repurchase $112.3 million of our 5.00% convertible subordinated notes due 2007 and $17.0 million in aggregate principal amount of our 5.75% convertible subordinated notes due 2006. In connection with these redemptions, we paid an additional $2.8 million for associated premiums. This offering was made under a Form S-3 Registration Statement with the Securities and Exchange Commission, file no. 333-81334, for which the effective date was April 29, 2002. EQUITY COMPENSATION PLANS The information required by this item regarding equity compensation plans is incorporated by reference to the information set forth in Item 12 of this annual report on Form 10-K. 20

ITEM 6. SELECTED FINANCIAL DATA SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA We have derived the selected historical consolidated financial data presented below for, and as of the end of, each of the years in the five-year period ended December 31, 2003 from our consolidated financial statements. You should read the selected consolidated financial data set forth below in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our consolidated financial statements and the related notes, included elsewhere in this annual report. The summary consolidated financial data below reflects the following transactions on a historical basis (i) our 1999 acquisition of the K4 factory from Anam Semiconductor, Inc.

In some cases, you can identify forward-looking statements by terminology such as "may," "will," "should," "expects," "plans," "anticipates," "believes," "estimates," "predicts," "potential," "continue," or the negative of these terms or other comparable terminology. Because such statements include risks and uncertainties, actual results may differ materially from those anticipated in such forward-looking statements as a result of certain factors, including those set forth in the following discussion as well as in "Risk Factors that May Affect Future Operating Performance." The following discussion provides information and analysis of our results of operations for the three years ended December 31, 2003 and our liquidity and capital resources. You should read the following discussion in conjunction with our consolidated financial statements and the related notes, included elsewhere in this annual report as well as other reports we file with the Securities and Exchange Commission. COMPANY OVERVIEW Amkor is one of the world's largest subcontractors of semiconductor packaging and test services. We have built a leading position by: - - Providing a broad portfolio of packaging and test technologies and services, - - Maintaining a leading role in the design and development of new package and test technologies, - - Cultivating long-standing relationships with customers, including many of the world's leading semiconductor companies, - - Developing expertise in high-volume manufacturing; and - - Diversifying our operational scope by providing production capabilities in China, Japan and Taiwan, in addition to long-standing capabilities in Korea and the Philippines. The semiconductors that we package and test for our customers ultimately become components in electronic systems used in communications, computing, consumer, industrial, automotive and military applications. Our customers include, among others, Atmel Corporation, Infineon Technologies AG, Intel Corporation, LSI Logic Corporation, Mediatek Inc., Philips Electronics N.V., ST Microelectronics PTE, Sony Semiconductor Corporation, Toshiba Corporation and Xilinx, Inc. The outsourced semiconductor packaging and test market is very competitive. We also compete with the internal semiconductor packaging and test capabilities of many of our customers, some of whom can use us as a source of overflow capacity. Packaging and test are an integral part of the semiconductor manufacturing process. Semiconductor manufacturing begins with silicon wafers and involves the fabrication of electronic circuitry into complex patterns, thus creating individual chips on the wafers. The packaging process creates an electrical interconnect between the semiconductor chip and the system board. In packaging, the fabricated semiconductor wafers are cut into individual chips which are then attached to a substrate and encased in a protective material to provide optimal electrical and thermal performance. Increasingly, packages are custom designed for specific chips and specific end-market applications. The packaged chips are then tested using sophisticated equipment to ensure that each packaged chip meets its design specifications. We historically marketed the output of fabricated semiconductor wafers provided by a wafer fabrication foundry owned and operated by Anam Semiconductor, Inc. ("ASI"). On February 28, 2003, we sold our wafer fabrication services business to ASI. We reflect our wafer fabrication services segment as a discontinued operation and have restated our historical results. 23

OUR EXPECTATIONS REGARDING FUTURE BUSINESS CONDITIONS Our business is tied to market conditions in the semiconductor industry, which is highly cyclical. Based on industry estimates, from 1981 through 2003, there were 12 years when semiconductor industry growth, measured by revenue dollars, was 10% or less and 11 years when growth was 16% or greater. Since 1981, the semiconductor industry declined in 1985, 1996, 1998 and 2001. The semiconductor industry declined an unprecedented 32% in 2001, experienced a 1% growth in 2002 as compared to 2001, and experienced 16% growth in 2003 as compared to 2002. The historical trends in the semiconductor industry are not necessarily indicative of the results of any future period. Semiconductor industry analysts are forecasting further growth in the semiconductor industry in both 2004 and 2005. 2004 is projected to increase approximately 19% over 2003, and 2005 is projected to increase approximately 6% over 2004. The strength of the semiconductor industry is dependent primarily upon the strength of the computer and communications systems markets as well as the strength of the worldwide economy. In addition to the historical trend in the semiconductor industry as a whole, the trend towards increased outsourcing of packaging and test services in the semiconductor industry has been a primary factor for our historical growth in revenues. We expect this trend to continue into the foreseeable future as we believe technological advances are driving our customers to outsource more of their packaging requirements. Although the first calendar quarter is typically a seasonally down quarter for us, we currently expect packaging and test revenue for the first quarter of 2004 to be around 2% to 4% higher than packaging and test revenues for the fourth quarter of 2003. We expect that first quarter of 2004 gross margin will be around 24%. Our profitability is dependent upon the utilization of our capacity, semiconductor package mix and the average selling price of our services. Because a substantial portion of our costs at our factories is fixed, relatively insignificant increases or decreases in capacity utilization rates can have a significant effect on our profitability. Prices for packaging and test services have declined over time. Historically, we have been able to partially offset the effect of price declines by successfully developing and marketing new packages with higher prices, such as advanced leadframe and laminate packages, by negotiating lower prices with our material vendors, and by driving engineering and technological changes in our packaging and test processes which resulted in reduced manufacturing costs. We expect that average selling prices for our packaging and test services will continue to decline in the future. If our semiconductor package mix does not shift to new technologies with higher prices or we cannot reduce the cost of our packaging and test services to offset a decline in average selling prices, our future operating results will suffer. Beginning in the second quarter of 2003, we began to experience increases in substrate material costs as a result of supply shortages. In the third quarter of 2003, substrate material costs stabilized at the higher price levels set during the second quarter of 2003. We have significantly enhanced our supply base and do not foresee substrate material availability as an ongoing issue. However, supply shortages may again occur in the future and in such an event, gross margins could be negatively impacted. In addition, the average price of gold has been increasing over the past few years. Although we have been able to partially offset the effect of gold price increases through price adjustments to customers and changes in our product designs, gold prices may continue to increase. To the extent that we are unable to offset these increases in the future, our gross margins could be negatively impacted. Average selling prices for 2003 declined 6% as compared to average selling prices in 2002. Average selling prices for 2002 declined 16% as compared to average selling prices in 2001. The impact of average selling price erosion on our gross margins in 2003 has diminished in comparison to 2002. RESULTS OF CONTINUING OPERATIONS The following table sets forth certain operating data as a percentage of net revenues for the periods indicated: YEAR ENDED DECEMBER 31, ----------------------- 2003 2002 2001 ------ ------ ------ Net revenues.................................................. 100.0% 100.0% 100.0% Gross profit.................................................. 21.0 6.8 3.9 Operating income (loss)....................................... 7.7 (29.6) (20.7) Loss before income taxes, equity investment losses, minority interest and discontinued operations............... (2.8) (40.1) (32.8) Net loss from continuing operations........................... (3.3) (59.4) (34.2) 24

YEAR ENDED DECEMBER 31, 2003 COMPARED TO YEAR ENDED DECEMBER 31, 2002 Net Revenues. Net revenues increased $197.6 million, or 14.1%, to $1,603.8 million in 2003 from $1,406.2 million in 2002. This increase in net revenues for 2003, excluding the impact of Amkor Iwate, was principally attributed to an overall unit volume increase of 19.9%. This increase in volume was driven by a 26.7% increase for advanced packages and an 11.5% increase in our traditional packages. Partially offsetting the volume increases, average selling prices for 2003 declined 6% as compared to average selling prices in 2002. Our Japanese joint venture, Amkor Iwate, provided packaging and test services principally to Toshiba's Iwate factory under a long-term supply agreement on a cost plus basis during the term of the joint venture. This joint venture ended in January 2004. Accordingly, the revenues associated with this facility fluctuate proportionately with its costs. The revenues of Amkor Iwate increased $17.6 million in 2003 compared to 2002 due primarily to higher costs associated with a shift in product mix, and to a lesser extent, the weakening of the U.S. dollar relative to the Japanese yen. Prices for packaging and test services have declined over time. Historically, we have been able to partially offset the effect of price declines by successfully developing and marketing new packages with higher prices, such as advanced leadframe and laminate packages, by negotiating lower prices with our material vendors, and by driving engineering and technological changes in our packaging and test processes which resulted in reduced manufacturing costs. Gross Profit (Loss). Gross profit increased $240.9 million, or 251.9%, to $336.5 million in 2003 from $95.6 million in 2002. Our cost of revenues consists principally of costs of materials, labor and depreciation. Because a substantial portion of our costs at our factories is fixed, relatively insignificant increases or decreases in capacity utilization rates can have a significant effect on our gross margin. Gross margins as a percentage of net revenues increased 14.2 percentage points to 21.0% in 2003 as compared to 6.8% in 2002 principally as a result of the following events at our factories, excluding Amkor Iwate: - Increased unit volumes contributed approximately 8 percentage points to the increase in gross margin. - Approximately 6 percentage points of the increase in gross margin was due to a reduction in depreciation costs of $101.6 million. $22.1 million of the reduced depreciation costs was attributable to the fixed asset impairment charge recorded during the second quarter of 2002, and approximately $46.1 million was the result of the change in estimated useful lives of certain packaging equipment beginning with the fourth quarter of 2002. The remaining decrease in depreciation costs is due to assets reaching fully depreciated status partially offset by an increase in depreciation costs related to capital expenditures. - Material cost savings contributed approximately 5 percentage points to the increase in gross margins. The positive impacts on gross margins were partially offset by: - Average selling price erosion across our product lines caused an estimated 5 percentage points decline in gross margins. Selling, General and Administrative Expenses. Selling, general and administrative expenses increased slightly by $0.1 million to $180.0 million, or 11.2% of net revenues, in 2003 from $179.9 million, or 12.8% of net revenues, in 2002. During 2003, we experienced a significant increase in our litigation costs as a result of the mold compound litigation matter. Legal fees associated with this mold compound litigation matter were $8.2 million during 2003, as opposed to $0.3 million in 2002. The increase in legal costs during 2003 was offset by savings from our administrative overhead cost reduction initiatives which began in 2002, including savings from certain facilities which were shutdown in 2002. Research and Development. Research and development expenses decreased $5.4 million to $25.8 million, or 1.6% of net revenues, in 2003 from $31.2 million, or 2.2% of net revenues, in 2002. The decrease in these costs was primarily attributable to our corporate cost reduction initiatives, which included closing our two U.S. research and development facilities during the second and third quarters of 2002 and consolidating these activities within our existing Asian-based research and development facilities. Our research and development efforts support our customers' needs for smaller packages and increased functionality. We continue to invest our research and development resources to further the development of flip chip interconnection solutions, chip scale packages that are nearly the size of the semiconductor die, MEMS devices used in a 25

variety of end markets including automotive, industrial and personal entertainment, our stacked chip packages that stack as many as three semiconductor dies in a single package, and System-in-Package technology, that uses both advanced packaging and traditional surface mount techniques to enable the combination of technologies in a single chip. We currently expect to increase our 2004 research and development expenditures by approximately 40% over our 2003 spending levels. Special Charges. During 2003, we recorded $0.1 million of special charges, as compared to $292.0 million in 2002. During 2003, a contract termination fee of $2.0 million was paid in order to terminate our commitment to purchase a tract of land adjacent to our Amkor Iwate facility. Also during 2003, we recorded a gain of $1.9 million related to the settlement of a pre-existing contingency. During 2002, we recorded $292.0 million of special charges which are further discussed below under "Significant Event, 2002 Special Charges." Other (Income) Expense. Other expenses, net, increased $20.9 million, to $168.3 million, or 10.5% of net revenues, in 2003 from $147.4 million, or 10.5% of net revenues, in 2002. Other expenses during 2003 primarily resulted from debt retirement costs of $37.8 million and losses of $5.7 million related to our ASI call options (discussed further below under Significant Events). These expenses were partially offset by a gain of $7.3 million related to the sale of our investment in an intellectual property company, our decrease in interest expense of $7.2 million, a gain of $4.7 million related to the sale of 12 million shares of common stock of ASI and an increase in foreign currency gains, net, of $3.9 million. Our $7.2 million decrease in interest expense was primarily as a result our of debt refinancing and debt repurchase activity during 2003. Provision (Benefit) for Income Taxes. We recorded an income tax benefit of $0.2 million in 2003, as compared to an income tax provision of $60.7 million in 2002. In 2002, in light of our three years of cumulative losses, an unprecedented industry downturn and continued poor visibility of customer demand, we determined that a valuation allowance representing substantially all of our deferred tax assets was appropriate. Accordingly, in 2003, there is only a modest tax benefit resulting from our losses from continuing operations primarily because we continue to record a valuation allowance for substantially all of our deferred tax assets generated. We will resume the recognition of deferred tax assets when we return to sustained profitability in our various tax jurisdictions. Further, we recorded a tax provision of $7.5 million related to our discontinued operations, for which we were able to record an offsetting tax benefit related to our continuing operations. We also reduced tax accruals, during 2003, by $20.0 million related to tax periods no longer open. These tax benefits have been offset by taxes related to our profitable foreign tax jurisdictions. We have remaining U.S. net operating losses available to be carried forward totaling $404.9 million expiring between 2021 and 2023. Additionally, at December 31, 2003, we have non-U.S. net operating losses available to be carried forward totaling $49.1 million expiring between 2004 and 2013. Equity Investment Losses. Our earnings include our share of losses in our equity affiliates in 2003 of $3.3 million, as compared to $208.2 million in 2002. In 2002, our earnings included our share of losses in our equity affiliates, principally ASI, in 2002 of $33.9 million and impairment charges totaling $172.5 million to reduce the carrying value of our investment in ASI to ASI's market value. Additionally during 2002, we recorded a loss of $1.8 million on the disposition of a portion of our interest in ASI. Our 2003 equity investment losses are comprised primarily of our share of losses from our investment in ASI during the period January 1, 2003 through March 23, 2003. On March 24, 2003, we divested 7 million shares of ASI which reduced our ownership percentage in ASI to 16% at that time, and we then ceased the equity method accounting for our investment in ASI. YEAR ENDED DECEMBER 31, 2002 COMPARED TO YEAR ENDED DECEMBER 31, 2001 Net Revenues. Net revenues increased $69.5 million, or 5.2%, to $1,406.2 million in 2002 from $1,336.7 million in 2001. This increase in net revenues for 2002, excluding the impact of our acquisitions and expansion in Japan, Taiwan and China, was principally attributed to an overall unit volume increase of 19.7% which was driven by a 42.0% increase for advanced packages and a 1.2% increase in our traditional packages. Partially offsetting the volume increases, average selling prices for 2002 declined 16% as compared to average selling prices in 2001. The revenues of Amkor Iwate declined $12.4 million in 2002 compared to 2001 due primarily to lower costs associated with a shift in product mix, and, to a lesser extent, the strengthening of the U.S. dollar relative to the Japanese yen. Our acquisitions in Taiwan and expansion into China contributed $54.6 million to the increase in net revenues for 2002. Prices for packaging and test services have declined over time. Historically, we have been able to partially offset the effect of price declines by successfully developing and marketing new packages with higher prices, such as advanced leadframe and laminate packages, by negotiating lower prices with our material vendors, and by driving engineering and technological changes 26

in our packaging and test processes which resulted in reduced manufacturing costs. During 2002, the decline in average selling prices significantly impacted our gross margins as compared to 2001. Gross Profit (Loss). Gross profit increased $43.4 million, or 83.0%, to $95.6 million in 2002 from $52.3 million in 2001. Our cost of revenues consists principally of costs of materials, labor and depreciation. Because a substantial portion of our costs at our factories is fixed, relatively insignificant increases or decreases in capacity utilization rates can have a significant effect on our gross margin. As a result of acquisitions in Japan and Taiwan in 2001 as well as other geographic expansions, we substantially increased our fixed costs. Gross margins as a percentage of net revenues increased 2.9 percentage points to 6.8% in 2002 as compared to 3.9% in 2001 principally as a result of the following: - Increased capacity utilization as a result of increased unit volumes at our factories in Korea and the Philippines together with the impact of our cost savings initiatives at those factories caused an approximate 8 percentage point increase in gross margins. - Material cost savings contributed approximately 5 percentage points to the increase in gross margins. - Reduced depreciation expense of approximately $39 million as a result of the impact of the fixed asset impairment charge recorded as of June 30, 2002 caused an approximate 2 percentage points increase in gross margins. - Reduced depreciation expense of approximately $17 million as a result of the impact of the change in estimated useful lives of certain packaging equipment beginning with the fourth quarter of 2002 caused an approximate 1 percentage point increase in gross margins. The positive impacts on gross margins were partially offset by: - Average selling price erosion across our product lines caused an estimated 12 percentage points decline in gross margins. - Our acquisitions in Taiwan and expansion into China contributed approximately 1.6 percentage points to the decline in gross margin as a result of the costs associated with ramping and reconfiguring operations at these facilities. Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased $11.2 million, or 5.9%, to $179.9 million, or 12.8% of net revenues, in 2002 from $191.1 million, or 14.3% of net revenues, in 2001. The decrease in these costs was largely attributed to $12.6 million in cost reductions principally related to our U.S. based administrative overhead cost reduction initiatives; partially offset by $0.9 million for increased administrative costs related to our factories. Our factory administrative expenses increased overall as a result of our 2002 and 2001 acquisitions offset by factory cost reduction initiatives. Research and Development. Research and development expenses decreased $7.6 million to $31.2 million, or 2.2% of net revenues, in 2002 from $38.8 million, or 2.9% of net revenues, in 2001. The decrease in these costs was primarily attributable to our corporate cost reduction initiatives, which included closing our two U.S. research and development facilities during the second and third quarters of 2002 and consolidating these activities within our existing Asian-based research and development facilities. Amortization of Goodwill and Other Acquired Intangibles. As of January 1, 2002, we adopted Statement of Financial Accounting Standard No. 142, Goodwill and Other Intangible Assets. We reclassified $30.0 million of intangible assets previously identified as an assembled workforce intangible to goodwill. Additionally, we stopped amortizing goodwill of $659.1 million. The cessation of amortization reduced amortization expense by $80.2 million for 2002 as compared with 2001. Special Charges. During 2002, we recorded $292.0 million of special charges which are further discussed below under "Significant Events, 2002 Special Charges." Other (Income) Expense. Other expenses, net decreased $14.0 million, to $147.4 million, or 10.5% of net revenues, in 27

2002 from $161.3 million, or 12.1% of net revenues, in 2001. The net decrease in other expenses was primarily the result of $13.4 million of unamortized deferred debt issuance costs expensed in connection with the repayment in February, May and November 2001 of term loans outstanding under our secured bank facility and the reduction of the revolving line of credit commitment. Provision (Benefit) for Income Taxes. During 2002, we recorded a $214.8 million charge to establish a valuation allowance against our deferred tax assets consisting primarily of U.S. and Taiwanese net operating loss carryforwards and tax credits. In connection with our divestiture in 2002 of 21 million shares of ASI common stock, we realized a capital loss of approximately $117.0 million and recognized a U.S. tax benefit of $44.5 million for which we provided a full valuation allowance because we did not have any offsetting capital gains. Generally accepted accounting principles require companies to weigh both positive and negative evidence in determining the need for a valuation allowance. In light of our three years of cumulative losses, an unprecedented industry downturn and continued poor visibility of customer demand, we determined in the fourth quarter that a valuation allowance representing substantially all of our deferred tax assets was appropriate. These negative factors outweighed our forecasted future profitability and expectation that we will be able to utilize our net operating loss carryforwards. In December 2002, we utilized $33.3 million of U.S. net operating losses by carrying back such amounts to offset U.S. reported taxable income in prior years. At December 31, 2002, our company has remaining U.S. net operating losses available to be carried forward totaling $375.5 million expiring between 2021 and 2022. Additionally, at December 31, 2002, our company had non-U.S. net operating losses available to be carried forward totaling $61.2 million expiring between 2003 and 2012. Equity Investment Losses. Our earnings included our share of losses in our equity affiliates, principally ASI, in 2002 of $33.9 million compared to $100.7 million ($65.2 million excluding the amortization of equity method goodwill) in 2001. As of January 1, 2002, we adopted Statement of Financial Accounting Standard No. 142, Goodwill and Other Intangible Assets. We stopped amortizing equity method goodwill of $118.6 million associated with our investment in ASI. The cessation of amortization reduced equity in loss of investees by $35.5 million for 2002 as compared with the corresponding period. During 2002, we recorded impairment charges totaling $172.5 million to reduce the carrying value of our investment in ASI to ASI's market value. Additionally during 2002, we recorded a loss of $1.8 million on the disposition of a portion of our interest in ASI to Dongbu. With Dongbu's purchase of 12.0 million newly issued shares of ASI together with its purchase of 20 million shares from our company and our disposition of an additional 1 million shares of ASI stock as payment of transaction costs to our financial advisors in connection with the transaction with Dongbu, our ownership interest in ASI was reduced to approximately 21%. RESULTS OF DISCONTINUED OPERATIONS On February 28, 2003, we sold our wafer fabrication services business to ASI. Additionally, we obtained a release from Texas Instruments regarding our contractual obligations with respect to wafer fabrication services to be performed subsequent to the transfer of the business to ASI. We restated our historical results to reflect our wafer fabrication services segment as a discontinued operation. In connection with the disposition of our wafer fabrication business, we recorded, in the first quarter of 2003, $1.0 million in severance and other exit costs to close our wafer fabrication services operations in Boise, Idaho and Lyon, France. Also in the first quarter of 2003, we recognized a pre-tax gain on the disposition of our wafer fabrication services business of $58.6 million ($51.5 million, net of tax). The carrying value of the sold net assets associated with the business as of February 28, 2003 was $2.4 million. SIGNIFICANT EVENTS OUR HISTORICAL RELATIONSHIP WITH ASI Historically, under a former supply agreement, we subcontracted for packaging and test services which were sourced from ASI's factories in Korea. Beginning in May 2000 with the completion of our acquisitions of ASI's packaging and test facilities, we no longer depend upon ASI for packaging or test services. In connection with the acquisition of the facilities, we committed to making equity investments in ASI and, as a result, accumulated a 42% ownership interest in ASI. Under a former wafer fabrication services supply agreement, we purchased the wafer output of ASI's wafer fabrication facility. As part of our strategy to sell our investment in ASI and to divest our wafer fabrication services business, we entered into the following series of transactions beginning in the second half of 2002: 28

- - In September 2002, we sold 20 million shares of ASI common stock to Dongbu Group in exchange for 5700 Korean won per share, the market value of ASI common stock as traded on the Korean Stock Exchange at the time we entered into the share sale agreement. We received $58.1 million in net cash proceeds and 42 billion won (approximately $34.2 million based on the spot exchange rate on the closing date) of interest bearing notes from Dongbu Corporation payable in two equal principal payments in September 2003 and February 2004. The Dongbu Group comprises Dongbu Corporation, Dongbu Fire Insurance Co., Ltd. and Dongbu Life Insurance Co., Ltd., all of which are Korean corporations and are collectively referred to herein as "Dongbu." Associated with this transaction, we recorded a $1.8 million loss. Additionally, we divested one million shares of ASI common stock in connection with the payment of certain advisory fees related to this transaction. On September 30, 2003, we received 21 billion won (approximately $18.3 million based on the spot exchange rate on the transaction date), consisting of the principal amount due under the notes from Dongbu. The remaining principal, or 21 billion won (approximately $17.8 million based on the spot exchange rate on the transaction date), was received on February 10, 2004. - - In separate transactions designed to facilitate a future merger between ASI and Dongbu, (i) we acquired a 10% interest in Acqutek from ASI for $1.9 million, the market value of the shares as publicly traded in Korea; (ii) we acquired the Precision Machine Division ("PMD") of Anam Instruments, a related party to Amkor, for $8 million, its fair value; and (iii) Anam Instruments, which had been partially owned by ASI, utilized the proceeds from the sale of PMD to us to buy back all of the Anam Instruments shares owned by ASI. Acqutek supplies materials to the semiconductor industry and is publicly traded in Korea. An entity controlled by the family of James Kim, our Chairman and Chief Executive Officer, held a 25% ownership interest in Acqutek at the time of our acquisition of our interest in Acqutek. We have historically purchased and continue to purchase leadframes from Acqutek. On September 17, 2003, we sold our entire ownership interest in Acqutek. PMD supplies sophisticated die mold systems and tooling to the semiconductor industry and historically over 90% of its sales were to Amkor. We determined the fair value of PMD based on projected cash flows discounted at a rate commensurate with the risk involved. At the time of our acquisition of PMD, Anam Instruments was owned 20% by ASI and 20% by a family member of James Kim. - - On February 28, 2003, we sold our wafer fabrication services business to ASI for $62 million. We negotiated the fair value of our wafer fabrication services business with ASI and Dongbu. The parties calculated fair value based on an assessment of projected cash flows discounted at a rate commensurate with the risk involved. We obtained a release from Texas Instruments regarding our contractual obligations with respect to wafer fabrication services to be performed subsequent to the transfer of the business to ASI. Each of the transactions with Dongbu, ASI and Anam Instruments are interrelated and it is possible that if each of the transactions were viewed on a stand-alone basis without regard to the other transactions, we could have had different conclusions as to fair value. It is likely that we would not have entered into the Acqutek or PMD transactions absent the share sale to Dongbu and the sale of the wafer fabrication services business to ASI. Had these transactions not been interrelated, we may have utilized a different negotiation strategy for the investment in Acqutek and the acquisition of PMD, which could have resulted in us reaching a different conclusion of the fair value of both of these transactions. Pursuant to the definitive agreements, (1) Amkor and Dongbu agreed to use reasonable best efforts to cause Dongbu Electronics and ASI to be merged together as soon as practicable, (2) Amkor and Dongbu agreed to cause ASI to use the proceeds ASI received from its sale of stock to Dongbu to purchase shares in Dongbu Electronics and (3) Amkor and Dongbu agreed to use their best efforts to provide releases and indemnifications to the chairman, directors and officers of ASI, either past or incumbent, from any and all liabilities arising out of the performance of their duties at ASI between January 1, 1995 and December 31, 2001. The last provision would provide a release and indemnification for James Kim, our CEO and Chairman, and members of his family. We are not aware of any claims or other liabilities which these individuals would be released from or for which they would receive indemnification. Subsequent to the sale of a portion of our investment in ASI to Dongbu in 2002, we were unable to identify another strategic buyer. ASI's common stock, which is listed on the Korean Stock Exchange, is relatively thinly traded and subject to volatile swings in daily trading volumes. In an effort to continue to monetize our investment in ASI's common stock, we evaluated, in consultation with a financial institution, the most efficient method to divest a large block of shares into the market without destabilizing the share price of ASI's common stock. On March 24, 2003, we consummated a series of transactions proposed by a financial institution. We irrevocably sold a block of 7 million shares of ASI common stock to the financial institution for approximately $19.5 million, or $2.81 per share. We also entered into a nondeliverable call option with the financial institution for $6.8 million, the fair value of the option at that date plus the transaction costs. In May 2003, we exercised the nondeliverable call option realizing $5.6 million of cash proceeds. Accordingly, during 2003 we recorded a loss of $1.2 million related to this nondeliverable call option. 29

On September 17, 2003, we sold an additional 5 million shares of ASI common stock to the same financial institution for approximately $18.5 million based on the spot exchange rate as of the transaction date, or $3.69 per share, and recorded an associated gain of $4.7 million during 2003. We also entered into a nondeliverable call option with the financial institution for $6.5 million, the fair value of the option at that date plus the transaction costs. In December 2003, we exercised the nondeliverable call option realizing $2.0 million of cash proceeds. Accordingly, during 2003 we recorded a loss of $4.5 million related to this nondeliverable call option. The March and September 2003 call options discussed above allowed us to continue to monetize our investment in ASI at a fixed price with unlimited upside and limited downside economics. In addition, it provided us with the economic benefits of selling shares through a dollar averaging sales program without incurring the transaction costs associated with multiple small quantity sales. The call premiums provided the financial institution some downward protection if the market for ASI's common stock destabilized as it sold its investment in ASI's common stock into the market. All ownership rights and privileges associated with the 12 million shares of ASI's common stock sold during 2003 were irrevocably transferred to the financial institution. In no event could the financial institution have put the shares back to Amkor nor was there a provision in the agreements for Amkor to reacquire the shares. 2002 SPECIAL CHARGES During 2002, we recorded $292.0 million of special charges. Special charges, in thousands, were comprised of: Impairment of long-lived assets ............................ $ 190,266 Impairment of goodwill ..................................... 73,080 Lease termination and other exit costs ..................... 28,624 --------- $ 291,970 ========= During 2001, the semiconductor industry declined an unprecedented 32%, which impacted the utilization rates of our packaging and test assets. During the second quarter of 2002, total packaging and test revenues grew over 21% as compared to the first quarter of 2002. We experienced significant recovery in most of our company's packaging services. However, our test services assets and several packaging services assets: - did not contribute significantly to the growth experienced during the second quarter of 2002, - remained at low utilization rates relative to our projections and - were no longer expected to reach previously anticipated utilization levels. In addition, as of June 30, 2002, we experienced a 72% decline in our market capitalization as compared to March 31, 2002. These events triggered an impairment review in accordance with Statement of Financial Accounting Standards ("SFAS") No. 144. This review included a company-wide evaluation of underutilized assets and a detailed update of our operating and cash flow projections. Based on our company-wide evaluation of underutilized assets, we identified $19.8 million of test and packaging assets to be disposed. We recognized an $18.7 million impairment charge to reduce the carrying value of the test and packaging fixed assets to be disposed to their fair value less cost to sell. Fair value of the assets to be disposed was determined with the assistance of an appraisal firm and available information on the resale value of the equipment. As of December 31, 2003, we have disposed of all of the identified test and packaging assets. Upon the completion of the process to identify the packaging and test net assets to be disposed, we reviewed our assets to be held and used for impairment. Based on the June 30, 2002 operating and cash flow projections, we determined that the carrying value of our test services assets and several packaging services assets being held and used, including intangible assets that we are amortizing, exceeded the anticipated cash flows attributable to those assets. We grouped our long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows were largely independent of the cash flows of other assets and liabilities. For our company, the lowest level of identifiable cash flows is at the test reporting unit level and for our packaging services reporting unit at the package type level. Our test reporting unit and the outsourced integrated circuit test services industry were adversely impacted by excess capacity at the large integrated device manufacturers. We expected that when the semiconductor industry recovered the 30

integrated device manufacturers demand for outsourced test services would also recover. However, that anticipated recovery failed to materialize in connection with the initial recovery we noted in the semiconductor industry during the first half of 2002 due to continued excess test capacity held by the large integrated device manufacturers. We no longer expected that the demand for our test services on our existing technology platforms would return to the previously anticipated rates. Several of our package types based on more mature technologies and processes, including older leadframe and laminate package types, were adversely impacted by a technology shift to matrix and high density leadframes and the movement from multi-layer laminate substrates to tape and chip arrays and stacked-die packages. We expected that when the semiconductor industry recovered there would still be sufficient demand for these more mature products. However, that anticipated recovery failed to materialize in connection with the initial recovery we noted in the semiconductor industry during the first half of 2002 due to these technology shifts and the related significant excess capacity in the industry. We no longer expected that the demand for these package types would return to the previously anticipated rates. Additionally, we experienced insufficient demand related to select investments in advanced package technologies principally as a result of alternative advanced package technologies which became industry standard. As of June 30, 2002, we recognized a $171.6 million impairment charge to reduce the carrying value of test and packaging assets to be held and used to their fair value. The components of the this charge were as follows: CARRYING FAIR IMPAIRMENT VALUE VALUE CHARGE ---------- ---------- ----------- (IN THOUSANDS) Test assets: Property, plant and equipment and acquired intangibles....... $ 95,400 $ 21,900 $ 73,500 Packaging assets: Property, plant and equipment............................... 157,700 59,600 98,100 ---------- ---------- ----------- $ 253,100 $ 81,500 $ 171,600 ========== ========== =========== An appraisal firm was engaged to assist in the determination of the fair value of the assets held for use. The determination of fair value was based on projected cash flows using a discount rate commensurate with the risk involved. Depreciation expense was reduced by $38.5 million during the six month period following the second quarter of 2002 and by $60.4 million for the year 2003. The impact to depreciation expense diminishes quarterly as these assets reach the end of their respective useful lives. SFAS No. 142 provides that goodwill of a reporting unit be tested for impairment on an annual basis and between annual tests in certain circumstances, including when a significant adverse change in the business climate occurs and when long-lived assets are tested for recoverability. Accordingly we retested goodwill for impairment as of June 30, 2002, and concluded that the carrying value of the assets and liabilities associated with the test services reporting unit exceeded its fair value. As of June 30, 2002, we recognized a $73.1 million goodwill impairment charge. Such impairment charge was measured by comparing the implied fair value of the goodwill associated with the test services reporting unit to its carrying value. An appraisal firm was engaged to assist in the determination of the fair value of our reporting units. The determination of fair value was based on projected cash flows using a discount rate commensurate with the risk involved. During 2003, we performed our annual review of goodwill for impairment. Based on our review, we concluded that goodwill was not impaired. During 2002, we recorded $28.6 million of charges related to the consolidation of our worldwide facilities to increase operational efficiency and reduce costs. The charges were comprised of $20.8 million to write-off leasehold improvements and other long-lived assets and $7.8 million for lease termination and other exit costs. Our consolidation efforts included: - Transferring the packaging operations at our K2 site in Bucheon, South Korea into our K4 factory in Kwangju, South Korea and closing the K2 facility, - Merging our factory operations in Taiwan into a single location, and - Consolidating select U.S. office locations and closing our San Jose test facility. The charges associated with the consolidation initiatives in Korea, Taiwan and the U.S. were $10.0 million, $13.8 million and $4.8 million, respectively. We completed the closing of the K2 facility during the second quarter of 2003 and the other 31

activities were substantially completed during 2002. We saved approximately $11.5 million during 2003 as a result of these consolidation efforts. CHANGE IN DEPRECIATION We calculate depreciation using the straight-line method over the estimated useful lives of the depreciable assets. We have historically estimated the useful lives of our machinery and equipment to be three to five years, with the substantial majority of our packaging assets having estimated useful lives of four years. Effective with the fourth quarter of 2002, we changed the estimated useful lives of certain of our packaging equipment from four years to seven years for depreciation purposes, which is in line with our historical usage and consistent with other companies in our industry. We did not extend the useful lives of the packaging equipment associated with the second quarter 2002 impairment charge based on our expected use of that equipment and the associated cash flows. This change reduced depreciation expense by approximately $17 million in the fourth quarter of 2002. This change further reduced depreciation expense by approximately $62 million in 2003. Our decision to change the estimated useful lives of such packaging equipment was based on the following: - historical experience, - expected future cash flows, - prevailing industry practice, - consultations with an independent appraisal firm, and - consultations with equipment manufacturers. We believe that our principal competitors depreciate their packaging assets over periods of six to eight years. OUR 2002 ACQUISITIONS In April 2002, we acquired the semiconductor packaging business of Citizen Watch Co., Ltd. located in the Iwate prefecture in Japan. The business acquired includes a manufacturing facility, over 80 employees and intellectual property. The purchase price included a $7.8 million cash payment at closing. We were required to make additional payments one year from closing for the amount of the deferred purchase price as well as contingent payments. Based on the resolution of the contingency as of January 2003, the total amount of additional payments due in April 2003 was 1.7 billion Japanese yen. In April 2003, we made a payment of 300.0 million Japanese yen, or $2.5 million based on the exchange rate on the date of the payment. We are withholding payment of 1.4 billion yen ($13.1 million based on the spot exchange rate at December 31, 2003) of this amount pending resolution of a controversy relating to the patents acquired in connection with the acquisition. We recorded $19.6 million of intangible assets for patent rights that are amortizable over 7 years. Our results of operation were not significantly impacted by this acquisition. In January 2002, we acquired Agilent Technologies, Inc.'s packaging business related to semiconductor packages utilized in printers for $2.8 million in cash. The acquired tangible assets were integrated into our existing manufacturing facilities. The purchase price was principally allocated to the tangible assets. Our results of operations were not significantly impacted by this acquisition. OUR VENTURE WITH TOSHIBA CORPORATION In January 2001, Amkor Iwate Corporation commenced operations and acquired from Toshiba a packaging and test facility located in the Iwate prefecture in Japan. At that time, we owned 60% of Amkor Iwate and Toshiba owned the balance of the outstanding shares. In January 2004, we acquired the remaining 40% ownership interest of Amkor Iwate from Toshiba for $12.8 million. Also in January 2004, we paid to Toshiba 220.0 million Japanese yen to terminate our commitment to purchase a tract of land adjacent to the Amkor Iwate facility. A $2.0 million charge was recorded in special charges during the fourth quarter of 2003 related to this termination fee. Amkor Iwate provides packaging and test services principally to Toshiba's Iwate factory under a long-term supply agreement that provides for services to be performed on a cost plus basis through December 2003 and then at market based rates beginning January 2004. This long-term supply agreement with Toshiba's Iwate factory terminates January 2006. 32

OUR ACQUISITIONS OF TAIWAN SEMICONDUCTOR TECHNOLOGY CORPORATION AND SAMPO SEMICONDUCTOR CORPORATION In July 2001, we acquired, in separate transactions, Taiwan Semiconductor Technology Corporation ("TSTC") and Sampo Semiconductor Corporation ("Sampo") in Taiwan. In connection with earn-out provisions that provided for additional purchase price based in part on the results of the acquisitions, we issued an additional 1.8 million shares of our common stock in January 2002 and recorded an additional $35.2 million in goodwill. The results of TSTC and Sampo have been included in our consolidated financial statements since the acquisition date. QUARTERLY RESULTS The following table sets forth our unaudited restated consolidated financial data, including as a percentage of our net revenues, for the last eight fiscal quarters ended December 31, 2003. Our results of operations have varied and may continue to vary from quarter to quarter and are not necessarily indicative of the results of any future period. The results of the semiconductor packaging businesses acquired from Citizen Watch Co., Ltd. and Agilent Technologies, Inc. in 2002 are included in the consolidated financial data from the date of the acquisitions. The quarterly results stated below reflect improved gross margins in the second half of 2002, as well as improved gross margins in each quarter of 2003. Related to the improvement in the second half of 2002, gross margins were positively impacted by the reduction of depreciation expense resulting from the fixed asset impairment charge recorded in the second quarter of 2002 and the impact of the change in the estimated useful lives of certain packaging equipment during the fourth quarter of 2002. Further, the second half of 2002 gross margins benefited from the impact of increased revenues from overall unit volumes and material cost reductions. Also, margins were improved as a result of consolidation efforts which reduced rental expense and depreciation. In 2002, the total cost reductions related to the impairment charge, change in useful lives and consolidation efforts positively impacted gross margins by approximately $20 million and $41 million in the third and fourth quarters of 2002, respectively. In 2003, the total cost reductions related to the impairment charge, change in useful lives and consolidation efforts positively impacted gross margins by approximately $34 million, $32 million, $33 million and $32 million in the first, second, third and fourth quarters of 2003, respectively. Also, our 2003 quarterly gross margins benefited from the impact of increased revenues from overall unit volumes and material cost reductions throughout the year. We believe that we have included in the amounts stated below all necessary adjustments, consisting only of normal recurring adjustments, for a fair presentation of our selected quarterly data. You should read our selected quarterly data in conjunction with our restated consolidated financial statements and the related notes, included elsewhere in this report. Our net revenues, gross profit and operating income are generally lower in the first quarter of the year as compared to the fourth quarter of the preceding year primarily due to the combined effect of holidays in the U.S. and Asia. Semiconductor companies in the U.S. generally reduce their production during the holidays at the end of December which results in a significant decrease in orders for packaging and test services during the first two weeks of January. In addition, we typically close our factories in the Philippines for holidays in January, and we close our factories in Korea for holidays in February. During the second quarter of 2003, in connection with our redemption of our $425 million senior notes due May 2006 we recorded charges of $19.7 million related to the premium paid in the redemption, $6.0 million for the associated unamortized deferred debt costs of $2.5 million of other costs; or $28.2 million in total, which is included in other expense, net. During the fourth quarter of 2003, we recorded a gain of $7.3 million related to the sale of our investment in an intellectual property company, which is included in other expense, net. The calculation of basic and diluted per share amounts for each quarter is based on the average shares outstanding for that period; consequently, the sum of the quarters may not necessarily be equal to the full year basic and diluted net income (loss) per share. 33

Our cash and cash equivalents balance as of December 31, 2003 was $313.3 million, and we had $30.0 million available under our $200.0 million senior secured credit facility. We believe that our existing cash balances, available credit lines, cash flow from operations and available equipment lease financing will be sufficient to meet our projected capital expenditures, debt service and working capital requirements for at least the next twelve months. We may require additional cash to consummate business combinations to diversify our geographic operations and expand our customer base. We intend to access the capital markets to meet these needs. We cannot assure you that additional financing will be available when we need it or, if available, that it will be available on satisfactory terms. In addition, the terms of the secured bank facility, senior notes and senior subordinated notes significantly reduce our ability to incur additional debt. Failure to obtain any such required additional financing could have a material adverse effect on us. Please refer to "Risk Factors That May Affect Future Operating Performance" below for further discussion. CASH FLOWS Net cash provided by (used in) operating, investing and financing activities from continuing operations and cash provided by discontinued operations for the three years ended December 31, 2003 were as follows: YEAR ENDED ------------------------------------------ DECEMBER 31, DECEMBER 31, DECEMBER 31, 2003 2002 2001 ------------ ------------ ------------ (IN THOUSANDS) Operating activities from continuing operations $ 176,346 $ 113,175 $ 140,964 Investing activities from continuing operations (167,096) (54,565) (168,110) Financing activities from continuing operations (22,012) (11,382) 114,686 Discontinued operations ....................... 13,284 62,631 19,397 Cash flows from continuing operating activities: Our 2003 cash flows from continuing operating activities increased $63.2 million to $176.4 million in 2003, from $113.2 in 2002. Our cash flows from continuing operating activities increased as a result of our improved operating performance, primarily driven by revenue increases, partially offset by our increased needs for working capital. The primary contributors to cash flow from continuing operations in 2003 were $223.2 million of cash flows provided by continuing operations (adjusted for non-cash items) and a $39.5 million increase in trade payables associated with the increase in business activity. These sources were primarily offset by a $77.2 million increase in accounts receivable resulting from increased revenues and average credit terms extending slightly due to higher mix of Asian based customers, and a $23.8 million increase in inventory levels required to accommodate the demand for our services. Cash flows from continuing investing activities: Our 2003 cash flows used in continuing investing activities increased by $112.5 as compared to 2002 primarily due to a $135.4 million increase in capital expenditures from $95.1 million in 2002 to $230.5 million in 2003. Cash used for capital expenditures in 2003 was offset by cash proceeds from the collection of $18.3 million of notes receivable from Dongbu in 2003, $38.0 million from the sale of ASI common stock in 2003 and $9.8 million from the sale of our investment in an intellectual property company during 2003. Cash flows from continuing financing activities: Our 2003 net cash outflows from continuing financing activities were $22.0 million, as compared to $11.4 million in 2002. In 2002, our financing activity was minimal and was related primarily to scheduled debt payments of $30.1 million offset by proceeds related to our stock compensation plans of $11.5 million. 35

During 2003, significant uses of cash for financing activities were primarily related our debt repurchase activity as follows: - In April 2003, we repaid our $96.9 million term loan with the proceeds received from a senior secured debt refinancing transaction, - In May 2003, we repaid our $425.0 million 9.25% senior notes due in 2006, primarily with the proceeds from the issuance of our new 7.75% senior notes due in 2013, - In November 2003, we repaid $112.3 million of our 5.0% convertible subordinated notes due 2007 and $17.0 million of our 5.75% convertible subordinated notes due June 2006 with the proceeds from our November 2003 7.4 million common share offering, - During 2003, we repaid $29.5 million of our 9.25% senior notes due 2008 with cash on hand, - During 2003, we repaid $42.2 million our outstanding foreign debt with cash on hand, - In connection with the above transactions, we paid $24.1 of debt call premiums, and - In connection with the new debt issuances discussed below, we incurred $10.6 million of debt acquisition costs. Cash used for financing activities during 2003 was offset by the following sources of cash: - In April 2003, we received $170.0 million of proceeds from a senior secured debt refinancing transaction, - In May 2003, we received $425.0 million of proceeds from the issuance of our new 7.75% senior notes due in 2013, - In November 2003, we received $133.5 million of net proceeds from our 7.4 million common share offering, and - During 2003, we received $13.5 million of proceeds related to our employee stock compensation plans. We engaged in these significant financing activities to reduce our level of outstanding debt, lower our cost of capital and enhance our financial flexibility. These transactions and the related financial instruments are discussed in greater detail below. DEBT INSTRUMENTS AND RELATED COVENANTS Following is a summary of short-term borrowings and long-term debt: DECEMBER 31, DECEMBER 31, 2003 2002 ------------- ------------- (IN THOUSANDS) Senior secured credit facilities: Term loan, LIBOR plus 4% due January 2006........................................ $ 168,725 $ -- $30.0 million revolving line of credit, LIBOR plus 4.25% due October 2005........ -- -- Senior credit facilities: Term B loans, LIBOR plus 4% due September 2005................................... -- 97,118 $100.0 million revolving line of credit, LIBOR plus 3.75% due March 2005......... -- -- 9.25% Senior notes due May 2006...................................................... -- 425,000 9.25% Senior notes due February 2008................................................. 470,500 500,000 7.75% Senior notes due May 2013...................................................... 425,000 -- 10.5% Senior subordinated notes due May 2009......................................... 200,000 200,000 5.75% Convertible subordinated notes due June 2006, convertible at $35.00 per share................................................... 233,000 250,000 5% Convertible subordinated notes due March 2007, convertible at $57.34 per share................................................... 146,422 258,750 Other debt........................................................................... 35,725 77,845 ------------- ------------- 1,679,372 1,808,713 Less -- Short-term borrowings and current portion of long-term debt (28,665) (71,023) ------------- ------------- $ 1,650,707 $ 1,737,690 ============= ============= We now have, and for the foreseeable future will continue to have, a significant amount of indebtedness. Our indebtedness requires us to dedicate a substantial portion of our cash flow from operations to service payments on our debt, with such payments principally for interest. For 2003, interest expense payable in cash was $140.3 million. 36

The covenants included in the agreements governing our existing debt, and debt we may incur in the future, may materially restrict our operations, including our ability to incur debt, pay dividends, make certain investments and payments and encumber or dispose of assets. In addition, financial covenants contained in agreements relating to our existing and future debt could lead to a default in the event our results of operations do not meet our plans and we are unable to amend such financial covenants prior to default. A default under one debt instrument may also trigger cross-defaults under our other debt instruments. As of December 31, 2003 and through the date of this filing, we were in compliance with all financial covenants. An event of default under one or more of our debt instruments, if not cured or waived, could have a material adverse effect on us. Our credit and debt ratings were lowered in August 2002, and accordingly, it may be difficult for us to secure additional financing, if we need it, on satisfactory terms or at all. Our business strategy has been, in part, to enhance our financial flexibility. During 2003, we have refinanced or repurchased various debt instruments, including our term loan and various senior notes, thereby lowering our effective interest rate and increasing our maturity dates. In April 2003, we entered into a new $200.0 million senior secured credit facility consisting of a $170.0 million term loan maturing January 31, 2006 and a $30.0 million revolving line of credit that is available through October 31, 2005. This new credit facility replaced the previously existing $196.9 million senior secured credit facility, which included a $96.9 million term loan and a $100.0 million revolving credit facility that were scheduled to mature September 30, 2005 and March 31, 2005, respectively. The new term loan bears interest at LIBOR plus 4.00% and the revolving line of credit bears interest at LIBOR plus 4.25%. These interest rates are subject to downward or upward adjustment according to respective improvements or deteriorations in our senior secured debt ratings. The remaining term loan principal repayments are due $1.7 million, $125.4 million and $41.6 million in 2004, 2005 and 2006, respectively. In addition, the credit facility includes certain affirmative, negative and financial covenants (including minimum EBITDA, as defined by the credit facility, minimum daily liquidity and maximum annual capital expenditures) and events of default, which are customary for credit facilities of this type. On October 17, 2003, we amended certain covenants under our new $200.0 million senior secured credit facility as follows: - our maximum annual capital expenditures have been increased to the greater of (i) $250 million or (ii) 50% of EBITDA (as defined), not to exceed $350 million, - we are permitted to repurchase or redeem any senior notes, senior subordinated notes or convertible notes with the net cash proceeds of equity offerings, - the basket for permitted investments has been increased from $25 million to $50 million, and - the annual basket for repurchases or redemptions of senior notes from cash (including proceeds of ASI shares) can be rolled over (to the extent unused) from year to year up to an aggregate amount of $300 million, of which up to $25 million may alternatively be used to repurchase or redeem senior subordinated notes or convertible notes. In May 2003, we received proceeds of $416.3 million, net of closing costs, in connection with our sale of $425.0 million of 7.75% senior notes due May 2013. We sold these notes to qualified institutional buyers and used the net proceeds of the issuance to redeem our outstanding 9.25% senior notes due 2006. The notes bear interest at the rate of 7.75 % annually and interest payments are due semi-annually. In connection with the redemption, we recorded charges during the second quarter of 2003 of $19.7 million related to the premium paid in the redemption, $6.0 million for the associated unamortized deferred debt issuance costs and $2.5 million of other costs. In November 2003, we sold 7,375,000 shares of our common stock priced at $19.00 per share. The final net proceeds to us were $133.5 million. These net proceeds were used to repurchase $112.0 million of our 5.00% convertible notes due 2007 and $17.0 million of our 5.75% convertible notes due 2006. In connection with this redemption, we recorded charges during the fourth quarter of 2003 of $2.8 million for the associated premiums paid and $2.3 million for the associated unamortized deferred debt issuance costs. Other debt as of December 31, 2003 and 2002 included our foreign debt principally related to the financing of Amkor Iwate's acquisition of a Toshiba packaging and test facility and the debt assumed in connection with the acquisition of Sampo Semiconductor Corporation in Taiwan. Our foreign debt included fixed and variable debt maturing between 2003 and 2010, with the substantial majority maturing by 2003. As of December 31, 2003, the foreign debt had interest rates ranging from 1.0% to 4.35%. These debt instruments do not include significant financial covenants. 37

CAPITAL EXPENDITURES AND CONTRACTUAL OBLIGATIONS We expect significant growth in our business in 2004 based on industry estimates for the semiconductor industry as a whole, and our expectation that the trend towards increased outsourcing of packaging and test services in the semiconductor industry will continue. Accordingly, we have budgeted first quarter capital expenditures of $200 million and will most likely spend between $300 million and $500 million in 2004, which may include business combinations to diversify our geographic operations and expand our customer base. A summary of our contractual obligations as of December 31, 2003 are as follows: PAYMENT DUE BY YEAR ENDING DECEMBER 31, --------------------------------------------------- 2005 - 2007 - AFTER TOTAL 2004 2006 2008 2009 ----------- ----------- ----------- ----------- ----------- (IN THOUSANDS) Total debt, including capital leases................... $ 1,679,372 $ 28,665 $ 406,539 $ 618,309 $ 625,859 Purchase obligations (1)............................... 148,805 148,805 -- -- -- Operating lease obligations............................ 133,824 10,935 16,238 16,664 89,987 Other long-term obligations (2)........................ -- -- -- -- -- ------------- ----------- ----------- ----------- ----------- Total contractual obligations.......................... $ 1,962,001 $ 188,405 $ 422,777 $ 634,973 $ 715,846 ============= =========== =========== =========== =========== (1) Includes $89.0 million of capital-related purchase obligations. (2) Our other noncurrent liabilities as of December 31, 2003 were $79.0 million. These other noncurrent liabilities included $76.3 million related to pension and severance obligations and $1.5 million related deferred tax liabilities, both of which are not included in the above chart due to uncertainty as to timing of payment. Also included in other noncurrent liabilities is an accrual of $1.2 million related to facility lease shutdowns, which is included in the chart above as operating lease obligations. Included in accrued expenses at December 31, 2003, and not included above, are the following: - In January 2004, we acquired the remaining 40% ownership interest of Amkor Iwate from Toshiba for $12.8 million. Also in January 2004, we paid to Toshiba 220.0 million Japanese yen to terminate our commitment to purchase a tract of land adjacent to the Amkor Iwate facility. A $2.0 million charge was recorded in other expense (income) during the fourth quarter of 2003 related to this termination fee. - In connection with our acquisition of a semiconductor packaging business from Citizen Watch Co., Ltd. we are required to make additional payments one year from closing for the amount of the deferred purchase price as well as contingent payments. Based on the resolution of the contingency as of January 2003, the total amount of additional payments due in April 2003 was 1.7 billion Japanese yen. In April 2003, we made a payment of 300.0 million Japanese yen, or $2.5 million based on the exchange rate on the date of the payment. We are withholding payment of 1.4 billion yen ($13.1 million based on the spot exchange rate at December 31, 2003) of this amount pending resolution of a controversy relating to the patents acquired in connection with the acquisition. OFF-BALANCE SHEET ARRANGEMENTS We had no off-balance sheet guarantees or other off-balance sheet arrangements as of December 31, 2003. CRITICAL ACCOUNTING POLICIES Financial Reporting Release No. 60, released by the Securities and Exchange Commission, requires all companies to include a discussion of critical accounting policies or methods used in the preparation of financial statements. We have identified the policies below as critical to our business operations and the understanding of our results of operations. A summary of our significant accounting policies used in the preparation of our consolidated financial statements appears in Note 1 of the notes to the consolidated financial statements. Our preparation of this annual report on Form 10-K requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenue and expenses during the reporting period. There can be no assurance that actual results will not differ from those estimates. Revenue Recognition and Risk of Loss. Revenues from packaging semiconductors and performing test services are recognized upon shipment or completion of the services. We do not take ownership of customer-supplied semiconductor 38

wafers. Title and risk of loss remains with the customer for these materials at all times. Accordingly, the cost of the customer-supplied materials is not included in the consolidated financial statements. Prior to the sales of our wafer fabrication services business on February 28, 2003, we recorded wafer fabrication services revenues upon shipment of completed wafers. Such policies are consistent with provisions in the Securities and Exchange Commission's Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements." Provision for Income Taxes. We operate in and file income tax returns in various U.S. and non-U.S. jurisdictions which are subject to examination by tax authorities. The tax returns for open years in all jurisdictions in which we do business are subject to changes upon examination. We believe that we have estimated and provided adequate accruals for the probable additional taxes and related interest expense that may ultimately result from examinations related to our transfer pricing and local attribution of income resulting from significant intercompany transactions, including ownership and use of intellectual property, in various U.S. and non-U.S. jurisdictions. Our estimated tax liability is subject to change as examinations of specific tax years are completed in the respective jurisdictions. We believe that any additional taxes or related interest over the amounts accrued will not have a material effect on our financial condition or results of operations, nor do we expect that examinations to be completed in the near term would have a material effect. As of December 31, 2003 and 2002, the accrual for current taxes and estimated additional taxes was $39.8 million and $48.8 million, respectively. While it is reasonably possible that future payments may exceed amounts accrued, we recorded a net tax benefit during the year ended December 31, 2003 of $20.0 million to reduce our tax accruals based on related tax periods no longer open. In addition, changes in the mix of income from our foreign subsidiaries, expiration of tax holidays and changes in tax laws or regulations could result in increased effective tax rates in the future. Additionally, we record the estimated future tax effects of temporary differences between the tax bases of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, as well as operating loss and tax credit carryforwards. Generally accepted accounting principles require companies to weigh both positive and negative evidence in determining the need for a valuation allowance for deferred tax assets. In 2002, in light of our three years of cumulative losses, an unprecedented industry downturn and continued poor visibility of customer demand, we determined that a valuation allowance representing substantially all of our deferred tax assets was appropriate. These negative factors outweighed our forecasted future profitability and expectation that we will be able to utilize our net operating loss carryforwards, and accordingly, during 2002 we recorded a $214.8 million charge to establish a valuation allowance against our deferred tax assets consisting primarily of U.S. and Taiwanese net operating loss carryforwards and tax credits. We will resume the recognition of deferred tax assets when we return to sustained profitability in certain jurisdictions. As of December 31, 2003, we had U.S. net operating losses totaling approximately $404.9 million expiring between 2021 and 2023. Additionally, as of December 31, 2003, we had approximately $49.1 million of non-U.S. net operating losses available for carryforward, expiring between 2004 and 2013. In connection with our divestiture in 2002 of 21 million shares of ASI common stock, we realized a capital loss of approximately $117.0 million and recognized a U.S. tax benefit of $44.5 million for which we provided a full valuation allowance because we did not have any offsetting capital gains. In connection with our divestiture in 2003 of 12 million shares of ASI common stock, we realized a capital loss of approximately $80.6 million and recognized a U.S. tax benefit of $32.2 million for which we provided a full valuation allowance because we did not have any offsetting capital gains. Valuation of Long-Lived Assets. We assess the carrying value of long-lived assets which includes property, plant and equipment, intangible assets and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important which could trigger an impairment review include the following: - significant under-performance relative to expected historical or projected future operating results, - significant changes in the manner of our use of the asset, - significant negative industry or economic trends, and - our market capitalization relative to net book value. Upon the existence of one or more of the above indicators of impairment, we would test such assets for a potential impairment. The carrying value of a long-lived asset is considered impaired when the anticipated cash flows are less than the asset's carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair 39

market value of the long-lived asset. Fair market value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved. Due to the existence of certain of the aforementioned indicators of impairment, we conducted a review in accordance with SFAS No. 144, "Accounting for the Impairment of Disposal of Long-Lived Assets," during the second quarter of 2002. As a result of this analysis, we identified $19.8 million of packaging and test fixed assets to be disposed and recognized an $18.7 million impairment charge to reduce the carrying values to their fair values less costs to sell. In addition, we recognized a $171.6 million impairment charge to reduce test and certain packaging assets that were to be held and used to their fair values based on projected cash flows discounted at a rate commensurate with the risk involved. In 2002, SFAS No. 142, "Goodwill and Other Intangible Assets" became effective and as a result, we ceased amortization of goodwill. In lieu of amortization, we were required to perform an initial impairment review of our goodwill as of January 1, 2002 and then on an annual basis or between annual tests in certain circumstances including a significant adverse change in the business climate and testing for recoverability of long-lived assets. Since we tested our long-lived assets for recoverability during the second quarter of 2002, we tested goodwill for impairment, and concluded that the carrying value of the assets and liabilities associated with the test services reporting unit exceeded its fair value. As a result, we recognized a $73.1 million goodwill impairment charge based on projected cash flows discounted at a rate commensurate with the risk involved. Depreciation accounting requires estimation of the useful lives of the assets to be depreciated as well as adoption of a method of depreciation. We have historically calculated depreciation using the straight-line method over the estimated useful lives of the depreciable assets. We have historically estimated the useful lives of our machinery and equipment to be three to five years, with the substantial majority of our packaging assets having estimated useful lives of four years. Effective with the fourth quarter of 2002, we changed the estimated useful lives of certain of our packaging equipment from four years to seven years for depreciation purposes, which is in line with our historical usage and consistent with other companies in our industry. We did not extend the useful lives of the packaging equipment associated with the second quarter impairment charge based on our expected use of that equipment and the associated cash flows. This change reduced depreciation expense by $38.5 million during the six month period following the second quarter of 2002 and by $60.6 million for the year 2003. Our decision to change the estimated useful lives of such packaging equipment was based on the following: - historical experience, - expected future cash flows, - prevailing industry practice, - consultations with an independent appraisal firm, and - consultations with equipment manufacturers. We believe that our principal competitors depreciate their packaging assets over periods of six to eight years. The change of the estimated useful lives is considered a change in estimate and was accounted for prospectively beginning with the fourth quarter of 2002. Legal contingencies. We are subject to certain legal proceedings, lawsuits and other claims. We assess the likelihood of any adverse judgment or outcome related to these matters, as well as potential ranges of probable losses. Our determination of the amount of reserves required, if any, for these contingencies is based on a careful analysis of each individual issue, often with the assistance of outside legal counsel. We record provisions in our consolidated financial statements for pending litigation when we determine that an unfavorable outcome is probable and the amount of the loss can be reasonably estimated. Regarding our epoxy mold compound litigation matter, claims against us may run in excess of $100 million. We have concluded that a loss is not probable, and are currently unable to estimate the amount or range of loss that could result in the event of an unfavorable outcome of this pending litigation. Accordingly, we have not provided any amounts in our consolidated financial statements for legal contingencies. 40

Our assessment of required reserves may change in the future due to new developments in each matter. The present legislative and litigation environment is substantially uncertain, and it is possible that our consolidated results of operations, cash flows or financial position could be materially affected by an unfavorable outcome or settlement of our pending litigation. We believe, and have been so advised by outside counsel handling these cases, that we have meritorious defenses to our litigation. All such cases are, and will continue to be, vigorously defended. Evaluation of Equity Investments. We evaluate our investments for impairment due to declines in market value that are considered other than temporary. In the event of a determination that a decline in market value is other than temporary, a charge to earnings is recorded for the unrealized loss. The stock prices of semiconductor companies' stocks, including ASI and its competitors, have experienced significant volatility during the past several years. During 2002, we recorded impairment charges totaling $172.5 million to reduce the carrying value of our investment in ASI to ASI's market value. At January 1, 2002, we owned 47.7 million shares of ASI common stock with a carrying value of $377.9 million. During the second half of 2002, we commenced a strategy to sell our investment in ASI. As of December 31, 2003, we have reduced our investment in ASI to 14.7 million shares with a carrying value of $50.4 million, including a $10.0 unrealized gain reflected in accumulated other comprehensive income. We intend to sell our remaining investment in ASI. The ultimate level of proceeds from the sale of our remaining investment in ASI could be less than the current carrying value. Valuation of Inventory. We order raw materials based on customers' forecasted demand and we do not maintain any finished goods inventory. If our customers change their forecasted requirements and we are unable to cancel our raw materials order or if our vendors require that we order a minimum quantity that exceeds the current forecasted demand, we will experience a build-up in raw material inventory. We will either seek to recover the cost of the materials from our customers or utilize the inventory in production. However, we may not be successful in recovering the cost from our customers or be able to use the inventory in production and accordingly if we believe that it is probable that we will not be able to recover such costs we adjust our reserve estimate. Additionally, our reserve for excess and obsolete inventory is based on forecasted demand we receive from our customers. When a determination is made that the inventory will not be utilized in production it is written-off and disposed. MARKET RISK SENSITIVITY We are exposed to market risks, primarily related to foreign currency and interest rate fluctuations. In the normal course of business, we employ established policies and procedures to manage the exposure to fluctuations in foreign currency values and changes in interest rates. Our use of derivatives instruments, including forward exchange contracts, has been insignificant throughout 2003 and 2002, and it is expected that our use of derivative instruments will continue to be minimal. FOREIGN CURRENCY RISKS Our primary exposures to foreign currency fluctuations are associated with transactions and related assets and liabilities denominated in Philippine pesos, Korean won, Japanese yen, and Taiwanese dollar and Chinese renminbi. The objective in managing these foreign currency exposures is to minimize the risk through minimizing the level of activity and financial instruments denominated in those currencies. Our foreign currency financial instruments primarily consist of cash, trade receivables, investments, deferred taxes, trade payables and accrued expenses. For an entity with various financial instruments denominated in a foreign currency in a net asset position, an increase in the exchange rate would result in less net assets when converted to U.S. dollars. Conversely, for an entity with various financial instruments denominated in a foreign currency in a net liability position, a decrease in the exchange rate would result in more net liabilities when converted to U.S. dollars. Based on our portfolio of foreign currency based financial instruments at December 31, 2003 and 2002, a 20% increase (decrease) in the foreign currency to U.S. dollar spot exchange rate would result in the following foreign currency risk for our entities in a net asset (liability) position: 41

CHART OF FOREIGN CURRENCY RISK ------------------------------------------------------------ PHILIPPINE KOREA TAIWANESE JAPANESE CHINESE PESO WON DOLLAR YEN RENMINBI ---------- ------- --------- -------- -------- (IN THOUSANDS) As of December 31, 2003 ...... $(3,269) $ 3,954 $(2,041) $ 3,718 $ 315 As of December 31, 2002 ...... $(1,782) $ 8,506 $ 1,933 $(7,589) $ (599) INTEREST RATE RISKS Our company has interest rate risk with respect to our long-term debt. As of December 31, 2003, we had a total of $1,679.4 million of debt of which 88.1% was fixed rate debt and 11.9% was variable rate debt. Our variable rate debt principally consisted of short-term borrowings and amounts outstanding under our secured bank facilities that included term loans and a $30.0 million revolving line of credit of which no amounts were drawn as of December 31, 2003. The fixed rate debt consisted of senior notes, senior subordinated notes, convertible subordinated notes and foreign debt. As of December 31, 2002, we had a total of $1,808.7 million of debt of which 91.3% was fixed rate debt and 8.7% was variable rate debt. Changes in interest rates have different impacts on our fixed and variable rate portions of our debt portfolio. A change in interest rates on the fixed portion of the debt portfolio impacts the fair value of the instrument but has no impact on interest incurred or cash flows. A change in interest rates on the variable portion of the debt portfolio impacts the interest incurred and cash flows but does not impact the fair value of the instrument. The fair value of the convertible subordinated notes is also impacted by the market price of our common stock. The table below presents the interest rates, maturities and fair value of our fixed and variable rate debt as of December 31, 2003. YEAR ENDING DECEMBER 31, ----------------------------------------------------------------- FAIR 2004 2005 2006 2007 2008 THEREAFTER TOTAL VALUE --------- ---------- ----------- ----------- ---------- ---------- ----------- ---------- Long-term debt: Fixed rate debt $ 2,543 $ 1,547 $ 233,867 $ 146,422 $ 470,500 $ 625,000 $1,479,879 $1,583,334 Average interest rate 4.3% 4.0% 5.7% 5.0% 9.3% 8.6% 8.0% Variable rate debt $ 26,122 $ 127,438 $ 43,687 $ 815 $ 572 $ 859 $ 199,493 $ 199,493 Average interest rate 1.6% 5.0% 4.9% 2.6% 2.7% 2.7% 4.5% EQUITY PRICE RISKS Our outstanding 5.75% convertible subordinated notes due 2006 and 5% convertible subordinated notes due 2007 are convertible into common stock at $35.00 per share and $57.34 per share, respectively. During the fourth quarter of 2003, we repurchased $112.3 million of our 5.00% convertible notes due 2007 and $17.0 million of our 5.75% convertible notes due 2006. We currently intend to repay our remaining convertible subordinated notes upon maturity, unless converted. If investors were to decide to convert their notes to common stock, our future earnings would benefit from a reduction in interest expense and our common stock outstanding would be increased. If we paid a premium to induce such conversion, our earnings could include an additional charge. Further, the trading price of our common stock has been and is likely to continue to be highly volatile and could be subject to wide fluctuations. Such fluctuations could impact our decision or ability to utilize the equity markets as a potential source of our funding needs in the future. RISK FACTORS THAT MAY AFFECT FUTURE OPERATING PERFORMANCE The following section discloses the known material risks facing our company. Additional risks and uncertainties not presently known to us, or that we currently deem immaterial, may also impair our business operations. We cannot assure you that any of the events discussed in the risk factors below will not occur. If they do, our business, financial condition or results of operations could be materially adversely affected. 42

This report contains forward-looking statements regarding our expected performance that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below. DEPENDENCE ON THE HIGHLY CYCLICAL SEMICONDUCTOR AND ELECTRONIC PRODUCTS INDUSTRIES -- WE OPERATE IN VOLATILE INDUSTRIES, AND INDUSTRY DOWNTURNS HARM OUR PERFORMANCE. Our business is tied to market conditions in the semiconductor industry, which is highly cyclical. Because our business is, and will continue to be, dependent on the requirements of semiconductor companies for subcontracted packaging and test services, any downturn in the semiconductor industry or any other industry that uses a significant number of semiconductor devices, such as the personal computer and telecommunication devices industries, could have a material adverse effect on our business. We experienced significant recovery in most of our packaging services during 2002 and 2003. Visibility has improved in light of customer forecasts and positive trends are forming. Beginning in the second half of 2003, a large number of customers over-supported their forecasts as demand materialized faster than initially projected. However, there still remains some uncertainty as to the sustainability of these trends. If industry conditions do not continue to improve, we could sustain significant losses which could materially impact our business, including our liquidity. FLUCTUATIONS IN OPERATING RESULTS -- OUR RESULTS HAVE VARIED AND MAY VARY SIGNIFICANTLY AS A RESULT OF FACTORS THAT WE CANNOT CONTROL. Many factors could materially and adversely affect our revenues, gross profit and operating income, or lead to significant variability of quarterly or annual operating results. Our profitability is dependent upon the utilization of our capacity, semiconductor package mix, the average selling price of our services and our ability to control our costs including labor, material, overhead and financing costs. Our operating results have varied significantly from period to period. During the three year period ended December 31, 2003, our revenues, gross margins and operating income have fluctuated significantly as a result of the following factors over which we have little or no control and which we expect to continue to impact our business: - fluctuation in demand for semiconductors and the overall health of the semiconductor industry, - changes in our capacity utilization, - declining average selling prices, - changes in the mix of semiconductor packages, - absence of backlog and the short-term nature of our customers' commitments and the impact of these factors on the timing and volume of orders relative to our production capacity, - changes in costs, availability and delivery times of raw materials and components, - changes in labor costs to perform our services, - the timing of expenditures in anticipation of future orders, - changes in effective tax rates, - high leverage and restrictive covenants, - international events that impact our operations and environmental events such as earthquakes, and - difficulties integrating acquisitions and our ability to attract qualified employees to support our geographic expansion. We have historically been unable to accurately predict the impact of these factors upon our results for a particular period. These factors, as well the factors set forth below which have not significantly impacted our recent historical results, may impair our future business operations and may materially and adversely affect our revenues, gross profit and operating income, or lead to significant variability of quarterly or annual operating results: - the availability and cost of financing for expansion, - loss of key personnel or the shortage of available skilled workers, - rescheduling and cancellation of large orders, - warranty and product liability claims, - intellectual property transactions and disputes, and - fluctuations in our manufacturing yields. 43

DECLINING AVERAGE SELLING PRICES -- THE SEMICONDUCTOR INDUSTRY PLACES DOWNWARD PRESSURE ON THE PRICES OF OUR PRODUCTS. Prices for packaging and test services have declined over time. Historically, we have been able to partially offset the effect of price declines by successfully developing and marketing new packages with higher prices, such as advanced leadframe and laminate packages, by negotiating lower prices with our material vendors, and by driving engineering and technological changes in our packaging and test processes which resulted in reduced manufacturing costs. During 2003 and 2002, as compared to the comparable prior year periods, the decline in average selling prices eroded margins by 6% and 16%, respectively. We expect that average selling prices for our packaging and test services will continue to decline in the future. If our semiconductor package mix does not shift to new technologies with higher prices or we cannot reduce the cost of our packaging and test services to offset a decline in average selling prices, our future operating results will suffer. HIGH LEVERAGE AND RESTRICTIVE COVENANTS -- OUR SUBSTANTIAL INDEBTEDNESS COULD MATERIALLY RESTRICT OUR OPERATIONS AND ADVERSELY AFFECT OUR FINANCIAL CONDITION. We now have, and for the foreseeable future will have, a significant amount of indebtedness. As of December 31, 2003, total debt was $1,679.4 million. In addition, despite current debt levels, the terms of the indentures governing our indebtedness may limit our ability to increase our indebtedness, but they do not prohibit us or our subsidiaries from incurring substantially more debt. If new debt is added to our consolidated debt level, the related risks that we now face could intensify. On April 22, 2003, we entered into a new $200 million senior secured credit facility consisting of a $170 million term loan which matures on January 31, 2006 and a $30 million revolving line of credit (under which no amounts are currently outstanding) which is available through October 31, 2005. The new credit facility replaces our previous $197 million senior secured credit facility, which included a $97 million term loan that was to mature September 30, 2005 and a $100 million revolving credit facility that was to be available through March 31, 2005. A portion of the proceeds from the term loan was used to repay the $97 million term loan then outstanding under the previous credit facility and the remainder of the proceeds will be used for general corporate purposes. In January 2004 we purchased the remaining 40% ownership interest of Amkor Iwate currently owned by Toshiba for $12.8 million. We were required to pay to Citizen Watch Co., Ltd. 1.7 billion Japanese yen in deferred purchase price and other contingent payments in connection with our purchase of the semiconductor packaging business of Citizen Watch Co, Ltd. In April 2003, we made a payment of 300.0 million Japanese yen, or $2.5 million based on the exchange rate on the date of the payment. We are withholding payment of 1.4 billion yen ($13.1 million based on the spot exchange rate at December 31, 2003) of this amount pending resolution of a controversy relating to the patents acquired in connection with the acquisition. In general, covenants in the agreements governing our existing debt, and debt we may incur in the future, may materially restrict our operations, including our ability to incur debt, pay dividends, make certain investments and payments and encumber or dispose of assets. In addition, financial covenants contained in agreements relating to our existing and future debt could lead to a default in the event our results of operations do not meet our plans and we are unable to amend such financial covenants prior to default. A default under one debt instrument may also trigger cross-defaults under our other debt instruments. As of December 31, 2003 and through the date of this filing, we were in compliance with all financial covenants. An event of default under one or more of our debt instruments, if not cured or waived, could have a material adverse effect on us. Our credit and debt ratings were lowered in August 2002, and accordingly, it may be difficult for us to secure additional financing, if we need it, on satisfactory terms or at all. Our substantial indebtedness could: - increase our vulnerability to general adverse economic and industry conditions, - limit our ability to fund future working capital, capital expenditures, research and development and other general corporate requirements, - require us to dedicate a substantial portion of our cash flow from operations to service interest and principal payments on our debt, - limit our flexibility to react to changes in our business and the industry in which we operate, - place us at a competitive disadvantage to any of our competitors that have less debt, and 44

- limit, along with the financial and other restrictive covenants in our indebtedness, among other things, our ability to borrow additional funds. INVESTMENT IN ASI -- OUR RESULTS AND FINANCIAL CONDITION MAY BE ADVERSELY AFFECTED BY DECREASES IN THE PRICE OF ASI'S COMMON STOCK. At December 31, 2003 we owned 14.7 million shares, or 12%, of ASI's voting stock. We currently account for our investment in ASI as a marketable security that is available for sale. We intend to sell our remaining investment in ASI. The ultimate level of proceeds from the sale of our remaining investment in ASI could be less than the current carrying value of $50.4 million. In addition, in the event of a decline in the market value of the ASI stock that is not temporary, we will be required to record a charge to earnings for the unrealized loss, and a new cost basis for the stock will be established. In connection with our sale of ASI shares to Dongbu in September 2002, Amkor and Dongbu agreed to use their best efforts to provide releases and indemnifications to the past and incumbent chairman, directors and officers of ASI, including James Kim, our CEO and chairman, and members of his family, from any and all liabilities arising out of the performance of their duties at ASI between January 1, 1995 and December 31, 2001. We are not aware of any claims or other liabilities which these individuals would be released from or for which they would receive indemnification. ABSENCE OF BACKLOG -- WE MAY NOT BE ABLE TO ADJUST COSTS QUICKLY IF OUR CUSTOMERS' DEMAND FALLS SUDDENLY. Our packaging and test business does not typically operate with any material backlog. We expect that in the future our quarterly net revenues from packaging and test will continue to be substantially dependent upon our customers' demand in that quarter. None of our customers have committed to purchase any significant amount of packaging or test services or to provide us with binding forecasts of demand for packaging and test services for any future period. In addition, our customers could reduce, cancel or delay their purchases of packaging and test services. Because a large portion of our costs is fixed and our expense levels are based in part on our expectations of future revenues, we may be unable to adjust costs in a timely manner to compensate for any revenue shortfall. RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS -- WE DEPEND ON OUR FACTORIES IN THE PHILIPPINES, KOREA, JAPAN, TAIWAN AND CHINA. MANY OF OUR CUSTOMERS' AND VENDORS' OPERATIONS ARE ALSO LOCATED OUTSIDE OF THE U.S. We provide packaging and test services through our factories located in the Philippines, Korea, Japan, Taiwan and China. Moreover, many of our customers' and vendors' operations are located outside the U.S. The following are some of the risks inherent in doing business internationally: - regulatory limitations imposed by foreign governments, - fluctuations in currency exchange rates, - political, military and terrorist risks, - disruptions or delays in shipments caused by customs brokers or government agencies, - unexpected changes in regulatory requirements, tariffs, customs, duties and other trade barriers, - difficulties in staffing and managing foreign operations, and - potentially adverse tax consequences resulting from changes in tax laws. DIFFICULTIES INTEGRATING ACQUISITIONS -- WE FACE CHALLENGES AS WE INTEGRATE NEW AND DIVERSE OPERATIONS AND TRY TO ATTRACT QUALIFIED EMPLOYEES TO SUPPORT OUR GEOGRAPHIC EXPANSION. As a result of our geographic expansion we have experienced, and expect to continue to experience, growth in the scope and complexity of our operations. For example, each business we have acquired had, at the time of acquisition, multiple systems for managing its own manufacturing, sales, inventory and other operations. Migrating these businesses to our systems typically is a slow, expensive process requiring us to divert significant amounts of resources from multiple aspects of our operations. This growth has strained our managerial, financial, manufacturing and other resources. Future acquisitions and expansions may result in inefficiencies as we integrate new operations and manage geographically diverse operations. Our success depends to a significant extent upon the continued service of our key senior management and technical personnel, any of whom would be difficult to replace. Competition for qualified employees is intense, and our business could be adversely affected by the loss of the services of any of our existing key personnel. Additionally, as part of our ongoing 45

strategic planning, we evaluate our management team and engage in long-term succession planning in order to ensure orderly replacement of key personnel. We cannot assure you that we will be successful in these efforts or in hiring and properly training sufficient numbers of qualified personnel and in effectively managing our growth. Our inability to attract, retain, motivate and train qualified new personnel could have a material adverse effect on our business. DEPENDENCE ON MATERIALS AND EQUIPMENT SUPPLIERS -- OUR BUSINESS MAY SUFFER IF THE COST, QUALITY OR SUPPLY OF MATERIALS OR EQUIPMENT CHANGES ADVERSELY. We obtain from various vendors the materials and equipment required for the packaging and test services performed by our factories. We source most of our materials, including critical materials such as leadframes, laminate substrates and gold wire, from a limited group of suppliers. Furthermore, we purchase all of our materials on a purchase order basis and have no long-term contracts with any of our suppliers. Our business may be harmed if we cannot obtain materials and other supplies from our vendors: (1) in a timely manner, (2) in sufficient quantities, (3) in acceptable quality or (4) at competitive prices. Beginning in the second quarter of 2003, we began to experience increases in substrate material costs as a result of supply shortages. Substrate material costs have stabilized at the higher price levels set during the second quarter of 2003. We have significantly enhanced our supply base and do not foresee substrate material availability as an ongoing issue. However, supply shortages may again occur in the future and in such an event, gross margins could be negatively impacted. In addition, the average price of gold has been increasing over the past few years. Although we have been able to partially offset the effect of gold price increases through price adjustments to customers and changes in our product designs, gold prices may continue to increase. To the extent that we are unable to offset these increases in the future, our gross margins could be negatively impacted. INCREASED LITIGATION INCIDENT TO OUR BUSINESS -- OUR BUSINESS MAY SUFFER AS A RESULT OF OUR INVOLVEMENT IN VARIOUS LAWSUITS. We are currently a party to various legal proceedings, including those described in Part I, Item 3 above. While we currently believe that the ultimate outcome of these proceedings, individually and in the aggregate, will not have a material adverse effect on our financial position or overall trends in results of operations, litigation is subject to inherent uncertainties. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on our net income in the period in which the ruling occurs. The estimate of the potential impact from the following legal proceedings on our financial position or overall results of operations could change in the future. As we discuss more fully in Part I, Item 3 above, recently we have become party to an increased number of litigation matters relative to our historic levels. Much of our recent increase in litigation relates to an allegedly defective epoxy mold compound, formerly used in some of our products, which is alleged to be responsible for certain semiconductor chip failures. RAPID TECHNOLOGICAL CHANGE -- OUR BUSINESS WILL SUFFER IF WE CANNOT KEEP UP WITH TECHNOLOGICAL ADVANCES IN OUR INDUSTRY. The complexity and breadth of semiconductor packaging and test services are rapidly changing. As a result, we expect that we will need to offer more advanced package designs in order to respond to competitive industry conditions and customer requirements. Our success depends upon our ability to develop and implement new manufacturing processes and package design technologies. The need to develop and maintain advanced packaging capabilities and equipment could require significant research and development and capital expenditures in future years. In addition, converting to new package designs or process methodologies could result in delays in producing new package types that could adversely affect our ability to meet customer orders. Technological advances also typically lead to rapid and significant price erosion and may make our existing products less competitive or our existing inventories obsolete. If we cannot achieve advances in package design or obtain access to advanced package designs developed by others, our business could suffer. COMPETITION -- WE COMPETE AGAINST ESTABLISHED COMPETITORS IN THE PACKAGING AND TEST BUSINESS. The subcontracted semiconductor packaging and test market is very competitive. We face substantial competition from 46

established packaging and test service providers primarily located in Asia, including companies with significant manufacturing capacity, financial resources, research and development operations, marketing and other capabilities. These companies also have established relationships with many large semiconductor companies that are current or potential customers. On a larger scale, we also compete with the internal semiconductor packaging and test capabilities of many of our customers. ENVIRONMENTAL REGULATIONS -- FUTURE ENVIRONMENTAL REGULATIONS COULD PLACE ADDITIONAL BURDENS ON OUR MANUFACTURING OPERATIONS. The semiconductor packaging process uses chemicals and gases and generates byproducts that are subject to extensive governmental regulations. For example, at our foreign manufacturing facilities, we produce liquid waste when silicon wafers are diced into chips with the aid of diamond saws, then cooled with running water. Federal, state and local regulations in the United States, as well as international environmental regulations, impose various controls on the storage, handling, discharge and disposal of chemicals used in our manufacturing processes and on the factories we occupy. Increasingly, public attention has focused on the environmental impact of semiconductor manufacturing operations and the risk to neighbors of chemical releases from such operations. In the future, applicable land use and environmental regulations may: (1) impose upon us the need for additional capital equipment or other process requirements, (2) restrict our ability to expand our operations, (3) subject us to liability or (4) cause us to curtail our operations. PROTECTION OF INTELLECTUAL PROPERTY -- WE MAY BECOME INVOLVED IN INTELLECTUAL PROPERTY LITIGATION. We maintain an active program to protect our investment in technology by acquiring intellectual property protection and enforcing our intellectual property rights. Intellectual property rights that apply to our various products and services include patents, copyrights, trade secrets and trademarks. We have filed and obtained a number of patents in the United States and abroad. We expect to continue to file patent applications when appropriate to protect our proprietary technologies, but we cannot assure you that we will receive patents from pending or future applications. In addition, any patents we obtain may be challenged, invalidated or circumvented and may not provide meaningful protection or other commercial advantage to us. We may need to enforce our patents or other intellectual property rights or defend ourselves against claimed infringement of the rights of others through litigation, which could result in substantial cost and diversion of our resources. The semiconductor industry is characterized by frequent claims regarding patent and other intellectual property rights. If any third party makes an enforceable infringement claim against us, we could be required to: - discontinue the use of certain processes, - cease the manufacture, use, import and sale of infringing products, - pay substantial damages, - develop non-infringing technologies, or - acquire licenses to the technology we had allegedly infringed. If we fail to obtain necessary licenses or if we are subjected to litigation relating to patent infringement or other intellectual property matters, our business could suffer. CONTINUED CONTROL BY EXISTING STOCKHOLDERS -- MR. JAMES KIM AND MEMBERS OF HIS FAMILY CAN SUBSTANTIALLY CONTROL THE OUTCOME OF ALL MATTERS REQUIRING STOCKHOLDER APPROVAL. As of December 31, 2003, Mr. James Kim and members of his family beneficially owned approximately 41.9% of our outstanding common stock. Mr. James Kim's family, acting together, will substantially control all matters submitted for approval by our stockholders. These matters could include: - the election of all of the members of our board of directors, - proxy contests, - mergers involving our company, - tender offers, and - open market purchase programs or other purchases of our common stock. 47

STOCK PRICE VOLATILITY The trading price of our common stock has been and is likely to continue to be highly volatile and could be subject to wide fluctuations in response to factors such as: - actual or anticipated quarter-to-quarter variations in operating results, - announcements of technological innovations or new products and services by Amkor or our competitors, - general conditions in the semiconductor industry, - changes in earnings estimates or recommendations by analysts, and - other events or factors, many of which are out of our control. In addition, the stock market in general, and the Nasdaq National Market and the markets for technology companies in particular, have experienced extreme price and volume fluctuations. This volatility has affected the market prices of securities of companies like ours for reasons that have often been unrelated or disproportionate to such companies' operating performance. These broad market fluctuations may adversely affect the market price of our common stock. ITEM 7A.

REPORT OF INDEPENDENT AUDITORS To the Board of Directors and Shareholders of Amkor Technology, Inc.: In our opinion, based on our audits and the reports of other auditors, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Amkor Technology, Inc. and its subsidiaries at December 31, 2003 and 2002, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2003 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits. For 2002 and 2001, we did not audit the combined financial statements of Amkor Technology Philippines, Inc. (formerly Amkor Technology Philippines (P1/P2), Inc. and Amkor Technology Philippines (P3/P4), Inc.), a wholly owned subsidiary, referred to herein as ATP, which combined financial statements reflect total assets of 14% of the consolidated total assets at December 31,2002 and operating expenses of 14% and 18% of the related consolidated total operating expenses for each of the two years in the period ended December 31, 2002. The combined financial statements of ATP as of December 31, 2002 and for the year ended December 31, 2002 were audited by another auditor whose report thereon has been furnished to us, and our opinion expressed herein, insofar as it relates to the amounts included for ATP, is based solely on the report of the other auditor. The financial statements of ATP as of December 31, 2001 and for the year ended December 31, 2001 were audited by other independent accountants who have ceased operations. Those independent accountants expressed an unqualified opinion on those financial statements in their report dated March 19, 2002. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, 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 and the reports of the other auditors provide a reasonable basis for our opinion. As discussed in Note 4 and Note 5, the Company adopted Statement of Financial Accounting Standards No. 142 "Goodwill and Other Intangibles" and No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets" as of January 1, 2002. /s/ PricewaterhouseCoopers LLP Philadelphia, Pennsylvania January 28, 2004 49

AMKOR TECHNOLOGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The consolidated financial statements include the accounts of Amkor Technology, Inc. and its subsidiaries. The consolidated financial statements reflect the elimination of all significant intercompany accounts and transactions. As discussed further below, we elected early adoption of FASB Interpretation No. ("FIN") 46, "Consolidation of Variable Interest Entities" on July 1, 2003. Accordingly, our investments in variable interest entities in which we are the primary beneficiary are consolidated. Our investments in variable interest entities in which we are not the primary beneficiary are accounted for under the equity method. Investments in and the operating results of 20% to 50% owned companies which are not variable interest entities are included in the consolidated financial statements using the equity method of accounting. Prior to the adoption of FIN 46, all investments in and the operating results of 20% to 50% owned companies were included in the consolidated financial statements using the equity method of accounting. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain previously reported amounts have been reclassified to conform with the current presentation. CONSOLIDATION OF VARIABLE INTEREST ENTITIES In January 2003, the Financial Accounting Standards Board (FASB) issued FIN 46, "Consolidation of Variable Interest Entities." The primary objective of FIN 46 is to provide guidance on the identification of, and financial reporting for, entities over which control is achieved through means other than voting rights; such entities are known as variable interest entities. FIN 46 requires variable interest entities to be consolidated by the primary beneficiary of the variable interest entities and expands disclosure requirements for both variable interest entities that are consolidated as well as those within which an enterprise holds a significant variable interest. On July 1, 2003, we elected early adoption of FIN 46 and have elected not to restate years prior to 2003. We have variable interests in certain Philippine realty corporations in which we have a 40% ownership and from whom we lease land and buildings in the Philippines. Beginning July 1, 2003, we have consolidated these Philippine realty corporations within our financial statements. As of December 31, 2003, the combined book value of the assets and liabilities associated with these Philippine realty corporations included in our consolidated balance sheet were $21.0 million and $1.0 million (which excludes an intercompany payable of $21.8 million which eliminates during consolidation), respectively. There was no net effect to our consolidated statements of income as a result of the consolidation of the Philippine realty corporations as these entities were previously accounted for as equity investments with our proportionate share of gains and losses recorded in our historical consolidated statements of income. In addition, the consolidation of Philippine realty companies was treated as a non-cash transaction. FOREIGN CURRENCY TRANSLATION The U.S. dollar is the functional currency of the majority of our subsidiaries in Korea and the Philippines, and the foreign currency asset and liability amounts at these subsidiaries are remeasured into U.S. dollars at end-of-period exchange rates, except for nonmonetary items which are remeasured at historical rates. Foreign currency income and expenses are remeasured at average exchange rates in effect during the year, except for expenses related to balance sheet amounts remeasured at historical exchange rates. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in other income (expense) in the period in which they occur. The local currency is the functional currency of our subsidiaries in Japan, Taiwan and China, and the asset and liability amounts of these subsidiaries are translated into U.S. dollars at end-of-period exchange rates. The resulting translation adjustments are reported as a component of accumulated other comprehensive income (loss) in the stockholders' equity section of the balance sheets. Assets and liabilities denominated in currency other than the local currency are remeasured into 54

the local currency prior to translation into U.S. dollars, and the resulting exchange gains or losses are included in other income (expense) in the period in which they occur. Income and expenses are translated into U.S. dollars at average exchange rates in effect during the period. CONCENTRATIONS AND CREDIT RISK Financial instruments, for which we are subject to credit risk, consist principally of accounts receivable, cash and cash equivalents and marketable securities. With respect to accounts receivable, we mitigate our credit risk by selling primarily to well established companies, performing ongoing credit evaluations and making frequent contact with customers. We have historically mitigated our credit risk with respect to cash and cash equivalents through diversification of our holdings into various high-grade money market accounts. RISKS AND UNCERTAINTIES Our future results of operations involve a number of risks and uncertainties. Factors that could affect future results and cause actual results to vary materially from historical results include, but are not limited to, dependence on the highly cyclical nature of the semiconductor industry, fluctuation in operating results, the decline in average selling prices, our high leverage and the restrictive covenants contained in the agreements governing our indebtedness, our investment in ASI, the absence of significant backlog in our business, our dependence on international operations and sales, difficulties integrating acquisitions, our dependence on materials and equipment suppliers, the increased litigation incident to our business, rapid technological change, competition, our need to comply with existing and future environmental regulations, the enforcement of intellectual property rights by or against us, continued control by existing stockholders and stock price volatility. CASH AND CASH EQUIVALENTS We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. INVENTORIES Inventories are stated at the lower of cost or market. Cost is determined principally by using a moving average method. We order raw materials based on the customers' forecasted demand and we do not maintain any finished goods inventory. If our customers change their forecasted requirements and we are unable to cancel our raw materials order or if our vendor requires that we order a minimum quantity that exceeds the current forecasted demand, we will experience a build-up in raw material inventory. We will either seek to recover the cost of the materials from our customers or utilize the inventory in production. However, we may not be successful in recovering the cost from our customers or successful in being able to use the inventory in production, which we would consider as part of our reserve estimate. Our reserve for excess and obsolete inventory is based on the forecasted demand we receive from our customers and the age of our inventory. When a determination is made that the inventory will not be utilized in production it is written-off and disposed. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost. Depreciation is calculated by the straight-line method over the estimated useful lives of depreciable assets. Accelerated methods are used for tax purposes. Depreciable lives follow: Buildings and improvements ................ 10 to 30 years Machinery and equipment ................... 3 to 7 years Furniture, fixtures and other equipment.... 3 to 10 years Effective with the fourth quarter of 2002, we changed the estimated useful lives of certain packaging equipment from four years to seven years for depreciation purposes, which is in line with our historical usage. This change increased our 2003 net income by approximately $62 million, or $0.37 per share, and decreased our 2002 net loss by approximately $16.7 million, or $0.10 per share. The offsetting impact to our tax provision in 2003 and 2002 related to the change in useful lives was immaterial due to tax holidays in certain tax jurisdictions and due to our recognition of valuation allowances against net operating loss carryforwards in certain other tax jurisdictions (see Note 17). 55

Cost and accumulated depreciation for property retired or disposed of are removed from the accounts and any resulting gain or loss is included in earnings. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation expense related to continuing operations was $211.0 million, $315.6 million and $354.5 million for 2003, 2002 and 2001, respectively. GOODWILL AND ACQUIRED INTANGIBLES Goodwill is recorded when the cost of an acquisition exceeds the fair market value of the net tangible and identifiable intangible assets acquired. On January 1, 2002, we adopted SFAS No. 142, "Goodwill and Other Intangible Assets" (see Note 5). The standard requires that goodwill and indefinite-lived intangible assets no longer be amortized. In addition, goodwill and indefinite-lived intangible assets are tested for impairment at least annually. These tests are performed more frequently if warranted. Impairment losses are recorded when the carrying amount of goodwill exceeds its implied fair value. Such impairment losses are recorded as a part of income from continuing operations. Definite-lived intangible assets include acquired patents and technology rights and are amortized on a straight-line basis over their estimated useful lives, generally for periods ranging from 5 to 10 years. We continually evaluate the reasonableness of the useful lives of these assets. The unamortized balances recorded for acquired intangibles are evaluated periodically for potential impairment. An impairment loss, if any, would be measured as the excess of the carrying value over the fair value. OTHER NONCURRENT ASSETS Other noncurrent assets consist principally of deferred income taxes and tax credits, deferred debt issuance costs and refundable security deposits. As discussed in Note 17, we have established valuation allowances against the majority of our deferred tax assets. At December 31, 2002, other noncurrent assets included $6.0 million for the cash surrender value of life insurance policies in which the beneficiary was our Chairman and CEO. In December 2003, our Chairman and CEO paid to us $6.0 million for this asset, the book value and fair value of the asset at that time, and accordingly, no balance exists at December 31, 2003. DUE FROM AND TO AFFILIATES At December 31, 2002, due from affiliates primarily related to advances made to Philippine realty companies in which we own 40%. Such investment was previously accounted for under the equity method of accounting. Beginning on July 1, 2003, we have consolidated these entities within our consolidated financial statement in accordance with FIN 46. Accordingly, this advance now eliminates during consolidation. The affiliated entities have no long-term obligations other than their obligations to us and we have not extended guarantees or other commitments to the entities. Due to affiliates primarily relates to our transactions with Anam Semiconductor, Inc. (see Note 8). Due from affiliates of $0.1 million and $0.3 million at December 31, 2003 and 2002, respectively, are included in accounts receivable - other. DEBT EXTINGUISHMENTS In April 2002, the FASB issued Statement of Financial Accounting Standards ("SFAS") No. 145, "Rescission of FASB Statements 4, 44, and 64, Amendment of FASB Statement 13, and Technical Corrections as of April 2002." SFAS 145 provides guidance for income statement classification of gains and losses on extinguishments of debt. Such gains and losses must be analyzed to determine if they meet the criteria for extraordinary item classification based on the event being both unusual and infrequent. We adopted SFAS 145 beginning January 1, 2003. During 2003, we charged $24.1 million of debt premiums, $11.1 million of associated unamortized deferred debt issuance costs and $2.5 million of other debt retirement costs to other (income) expense, net. During 2001, we charged $13.4 million of unamortized deferred debt issuance costs to other (income) expense, net. OTHER NONCURRENT LIABILITIES Other noncurrent liabilities consist primarily of Korean severance plan obligations, Philippine pension obligations and 56

noncurrent income taxes payable. RECEIVABLE FROM STOCKHOLDERS Amkor Electronics, Inc. (AEI), which was merged into our company just prior to the initial public offering of our company in May 1998, elected to be taxed as an S Corporation under the provisions of the Internal Revenue Code of 1986 and comparable state tax provisions. As a result, AEI did not recognize U.S. federal corporate income taxes. Instead, the stockholders of AEI were taxed on their proportionate share of AEI's taxable income. Accordingly, no provision for U.S. federal income taxes was recorded for AEI. Just prior to the initial public offering, AEI terminated its S Corporation status at which point the profits of AEI became subject to federal and state income taxes at the corporate level. We consummated a tax indemnification agreement between us, our predecessor and James Kim and his family (collectively, the "Kim Family"). James Kim, is our founder and significant stockholder, and currently serves as our Chairman and CEO. Under the terms of the tax indemnification agreement, Amkor indemnified the former owners of AEI for the settlement of AEI's S Corporation federal and state tax returns and any adjustments to the reported taxable income. During 2003, all tax years in which AEI filed U.S. federal income tax returns are closed and, accordingly, are no longer subject to review. At the time AEI was converted to a C Corporation, AEI and the Kim Family identified certain federal and state tax overpayments associated with the results of AEI during S Corporation status years, and AEI, in May 1998, paid such amounts to the Kim Family. These amounts, which principally related to the finalization of AEI's federal tax return, have been reflected as a receivable from stockholders in the stockholders' equity section of our balance sheets. During the fourth quarter of 2003, the receivable was collected in full. REVENUE RECOGNITION AND RISK OF LOSS Our company does not take ownership of customer-supplied semiconductor wafers. Title and risk of loss remains with the customer for these materials at all times. Accordingly, the cost of the customer-supplied materials is not included in the consolidated financial statements. Revenues from packaging semiconductors and performing test services are recognized upon shipment or completion of the services. Such policies are consistent with provisions in the Securities and Exchange Commission's Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements." STOCK COMPENSATION We apply Accounting Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to Employees," and related Interpretations, to our stock option plans. These stock option plans are discussed more fully in Note 19, "Stock Compensation Plans." No compensation expense has been recognized for our employee stock options that have been granted. If compensation costs for our stock option plans had been determined using the fair value method of accounting as set forth in SFAS No. 123, "Accounting for Stock-Based Compensation," our reported net income (loss) and per share amount would have been increased (decreased). The following table illustrates the effect on net income (loss) and per share amounts as if the fair value based method had been applied to all outstanding and unvested awards in each period. Refer to Note 19 for a discussion of the assumptions used in calculating the fair value of the options granted. FOR THE YEAR ENDED DECEMBER 31, --------------------------------------- 2003 2002 2001 --------- --------- --------- (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS) Net income (loss): Net income (loss), as reported ....................... $ 2,198 $(826,759) $(450,861) Deduct: Total stock-based employee compensation determined under fair value based method, net of tax ..................................

(0.18) (5.29) (3.06) 57

For 2003 and 2002 pro forma net losses, there was no offsetting impact to our tax provision related to the pro forma Black-Scholes stock option expense because of our consolidated net losses for 2003 and 2002 and our associated recognition of valuation allowances against net operating loss carryforwards (see Note 17). RESEARCH AND DEVELOPMENT COSTS Research and development expenses include costs directly attributable to the conduct of research and development programs primarily related to the development of new package designs and improving the efficiency and capabilities of our existing production process. Such costs include salaries, payroll taxes, employee benefit costs, materials, supplies, depreciation on and maintenance of research equipment, fees under licensing agreements, services provided by outside contractors, and the allocable portions of facility costs such as rent, utilities, insurance, repairs and maintenance, depreciation and general support services. All costs associated with research and development are expensed as incurred. RECENTLY ISSUED ACCOUNTING STANDARDS In May 2003, FASB issued Statement of Financial Accounting Standard ("SFAS") No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity." SFAS 150 establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. SFAS 150 was effective for financial instruments entered into or modified after May 31, 2003, and otherwise was effective at the beginning of the first interim period beginning after June 15, 2003. In November 2003, FASB issued "FASB Staff Position No. FAS 150-3," which deferred indefinitely the measurement provisions of SFAS 150 for certain mandatorily redeemable noncontrolling interests that were issued before November 5, 2003. The adoption of SFAS 150 did not have a material effect on our financial position, results of operations, or cash flows. In December 2003, the FASB issued SFAS No. 132 (revised 2003), "Employers' Disclosures about Pensions and Other Postretirement Benefits." This statement requires additional disclosures about the assets, obligations, cash flows, and net periodic benefit cost of defined benefit pension plans and other postretirement plans. The statement does not change the measurement or recognition of pension plans and other postretirement benefit plans. For domestic plans, the new disclosures are generally effective for periods ending after December 15, 2003. For foreign plans, the new disclosures are generally effective for periods ending after June 15, 2004. All of our defined benefit pension plans are foreign. The adoption of SFAS No. 132 (revised 2003) is not expected to have a material effect on our financial position, results of operations, or cash flows. 2. DISCONTINUED OPERATIONS On February 28, 2003, we sold our wafer fabrication services business to ASI. Additionally, we obtained a release from Texas Instruments regarding our contractual obligations with respect to wafer fabrication services to be performed subsequent to the transfer of the business to ASI. We restated our historical results to reflect our wafer fabrication services segment as a discontinued operation. In connection with the disposition of our wafer fabrication business, we recorded, during the first quarter of 2003, $1.0 million in severance and other exit costs to close our wafer fabrication services operations in Boise, Idaho and Lyon, France. Also in the first quarter of 2003, we recognized a pre-tax gain on the disposition of our wafer fabrication services business of $58.6 million (or $51.5 million net of $7.1 million of associated tax expense). The carrying value of the sold net assets associated with the business as of February 28, 2003 was $2.4 million. A summary of the results from discontinued operations for the years ended December 31, 2003, 2002 and 2001 are as follows: 58

SFAS NO. 144, ACCOUNTING FOR THE IMPAIRMENT OR DISPOSAL OF LONG-LIVED ASSETS In August 2001, the FASB issued SFAS No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets," which supersedes SFAS No. 121. This standard provides a single accounting model for long-lived assets to be disposed of by sale and establishes additional criteria that would have to be met to classify an asset as held for sale. The carrying amount of an asset or asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group. Estimates of future cash flows used to test the recoverability of a long-lived asset or asset group must incorporate the entity's own assumptions about its use of the asset or asset group and must factor in all available evidence. SFAS No. 144 requires that long-lived assets be tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. Such events include significant under-performance relative to the expected historical or projected future operating results; significant changes in the manner of use of the assets; significant negative industry or economic trends and significant changes in market capitalization. During 2001, the semiconductor industry declined an unprecedented 32%, which impacted the utilization rates of our packaging and test assets. During the second quarter of 2002, total packaging and test revenues grew over 21% as compared to the first quarter of 2002. We experienced significant recovery in most of our company's packaging services. However, at that time, our test services assets and several packaging services assets: - did not contribute significantly to the growth experienced during the second quarter of 2002, 59

- remained at low utilization rates relative to our projections and - were no longer expected to reach previously anticipated utilization levels. In addition, as of June 30, 2002, we experienced a 72% decline in our market capitalization as compared to March 31, 2002. These events triggered an impairment review in accordance with SFAS No. 144. This review included a company-wide evaluation of underutilized assets and a detailed update of our operating and cash flow projections. Based on our company-wide evaluation of underutilized assets during 2002, we identified $19.8 million of test and packaging assets to be disposed. We recognized an $18.7 million impairment charge to reduce the carrying value of the test and packaging fixed assets to be disposed to their fair value less cost to sell. Fair value of the assets to be disposed was determined with the assistance of an appraisal firm and available information on the resale value of the equipment. As of December 31, 2003, we have disposed of all of the identified test and packaging assets. Upon the completion of the process to identify the packaging and test net assets to be disposed, we reviewed our assets to be held and used for impairment. Based on the June 30, 2002 operating and cash flow projections, we determined that the carrying value of our test services assets and several packaging services assets being held and used, including intangible assets that we are amortizing, exceeded the anticipated cash flows attributable to those assets. We grouped our long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows were largely independent of the cash flows of other assets and liabilities. For our company, the lowest level of identifiable cash flows is at the test reporting unit level and for our packaging services reporting unit at the package type level. Our test reporting unit and the outsourced integrated circuit test services industry were adversely impacted by excess capacity at the large integrated device manufacturers. We expected that when the semiconductor industry recovered the integrated device manufacturers' demand for outsourced test services would also recover. However, that anticipated recovery failed to materialize in connection with the initial recovery we noted in the semiconductor industry during the first half of 2002 due to continued excess test capacity held by the large integrated device manufacturers. We no longer expected that the demand for our test services on our existing technology platforms would return to the previously anticipated rates. Several of our package types based on more mature technologies and processes, including older leadframe and laminate package types, were adversely impacted by a technology shift to matrix and high density leadframes and the movement from multi-layer laminate substrates to tape and chip arrays and stacked-die packages. We expected that when the semiconductor industry recovered there would still be sufficient demand for these more mature products. However, that anticipated recovery failed to materialize in connection with the initial recovery we noted in the semiconductor industry during the first half of 2002 due to these technology shifts and the related significant excess capacity in the industry. We no longer expected that the demand for these package types would return to the previously anticipated rates. Additionally, we experienced insufficient demand related to select investments in advanced package technologies principally as a result of alternative advanced package technologies which became industry standard. As of June 30, 2002, we recognized a $171.6 million impairment charge to reduce the carrying value of test and packaging assets to be held and used to their fair value. The components of this charge were as follows: CARRYING FAIR IMPAIRMENT VALUE VALUE CHARGE ------------- ------------- ------------- (IN MILLIONS) Test assets: Property, plant and equipment and acquired intangibles.... $ 95.4 $ 21.9 $ 73.5 Packaging assets: Property, plant and equipment............................. 157.7 59.6 98.1 ------------- ------------- ------------- $ 253.1 $ 81.5 $ 171.6 ============= ============= ============= An appraisal firm was engaged to assist in the determination of the fair value of the assets held for use. The determination of fair value was based on projected cash flows using a discount rate commensurate with the risk involved. 5. SFAS NO. 141, BUSINESS COMBINATIONS AND SFAS NO. 142, GOODWILL AND OTHER INTANGIBLE ASSETS In June 2001, the FASB issued SFAS No. 141, "Business Combinations," which prohibits the pooling-of-interests method 60

of accounting for business combinations initiated after June 30, 2001 and addresses the accounting for purchase method business combinations completed after June 30, 2001. Also in June 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets." For existing acquisitions, the provisions of SFAS No. 142 were effective as of January 1, 2002 and are generally effective for business combinations initiated after June 30, 2001. SFAS No. 142 includes provisions regarding the reclassification of certain existing recognized intangibles as goodwill, reassessment of the useful lives of existing recognized intangibles, the cessation of amortization related to goodwill and indefinite-lived intangibles, and the testing for impairment of goodwill and other intangibles annually or more frequently if circumstances warrant. Additionally, SFAS No. 142 requires that within six months of adoption of SFAS No. 142, goodwill be tested for impairment at the reporting unit level as of the date of adoption. We adopted SFAS No. 142 as of January 1, 2002 and we reclassified $30.0 million of intangible assets previously identified as an assembled workforce intangible to goodwill. Additionally, at adoption of SFAS No. 142 we stopped amortizing goodwill of $659.1 million, as well as goodwill of $118.6 million associated with our investment in ASI then accounted for under the equity method of accounting. The as adjusted financial information below assumes that the cessation of amortization occurred as of January 1, 2001. FOR THE YEAR ENDED DECEMBER 31, ----------------------------------------- 2003 2002 2001 ----------- ----------- ----------- (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS) Loss from continuing operations, as reported ............. $ (52,368) $ (835,089) $ (456,487) ----------- ----------- ----------- Goodwill and assembled workforce amortization ............ -- -- 80,232 Goodwill related to equity investments ................... -- -- 35,544 ----------- ----------- ----------- -- -- 115,776 ----------- ----------- ----------- Loss from continuing operations, as adjusted .............

Goodwill and other intangible assets are attributable to two reporting units, packaging and test services. Goodwill is allocated to each reporting unit proportionate to the fair values of the acquired packaging and test assets. We completed the initial impairment test during the second quarter of 2002. Based on the comparison of the fair value of the reporting units with their respective carrying values each as of January 1, 2002, we concluded that goodwill associated with our packaging and test services reporting units was not impaired as of adoption. An appraisal firm was engaged to assist in the determination of the fair value of our reporting units. The determination of fair value was based on projected cash flows using a discount rate commensurate with the risk involved. SFAS No. 142 provides that goodwill of a reporting unit be tested for impairment on an annual basis and between annual tests in certain circumstances including a significant adverse change in the business climate and testing for recoverability of long-lived assets. Our test services assets and several packaging services assets remained at low utilization rates during the second quarter of 2002 and were no longer expected to reach previously anticipated utilization levels. As discussed in Note 4, we tested the recoverability of such assets as of June 30, 2002 and concluded that a portion of those assets was impaired. Accordingly, we retested goodwill for impairment as of June 30, 2002, and concluded that the carrying value of the assets and liabilities associated with the test services reporting unit exceeded its fair value. As of June 30, 2002, we recognized a $73.1 million goodwill impairment charge. Such impairment charge was measured by comparing the implied fair value of the goodwill associated with the test services reporting unit to its carrying value. An appraisal firm was engaged to assist in the determination of the fair value of our reporting units. The determination of fair value was based on projected cash flows using a 61

discount rate commensurate with the risk involved. During the second quarter of 2003, we performed our annual review for impairment and concluded that goodwill was not impaired. The changes in the carrying value of goodwill by reporting unit are as follows: PACKAGING TEST SERVICES SERVICES TOTAL -------- -------- --------- (IN THOUSANDS) Balance as of January 1, 2002 .............................. $586,344 $ 72,786 $ 659,130 Goodwill acquired .......................................... 40,890 -- 40,890 Goodwill impairment ........................................ -- (73,080) (73,080) Translation adjustments .................................... 865 294 1,159 -------- -------- --------- Balance as of December 31, 2002 ............................ $628,099 $ -- $ 628,099 Translation adjustments .................................... 1,751 -- 1,751 -------- -------- --------- Balance as of December 31, 2003 ............................ $629,850 $ -- $ 629,850 ======== ======== ========= 6. RESTRUCTURING CHARGES During 2002, we recorded $28.6 million of charges related to the consolidation of our worldwide facilities to increase operational efficiency and reduce costs. The charges were comprised of $20.8 million to write-off leasehold improvements and other long-lived assets and $7.8 million for lease termination and other exit costs. Our consolidation efforts included: - Transferring the packaging operations at our K2 site in Bucheon, South Korea into our K4 factory in Kwangju, South Korea and closing the K2 facility, - Merging our factory operations in Taiwan into a single location, and - Consolidating select U.S. office locations and closing our San Jose test facility. The 2002 charges associated with the consolidation initiatives in Korea, Taiwan and the U.S. were $10.0 million, $13.8 million and $4.8 million, respectively. We completed the closing of the K2 facility during the second quarter of 2003 and the other activities were substantially completed during 2002. Of the total $28.6 million restructuring charges recorded in 2002, $2.2 million and $6.1 million remained outstanding as of December 31, 2003 and December 31, 2002, respectively, and is reflected in accrued expenses and other noncurrent liabilities. The outstanding liability is principally future lease payments of which $1.0 million is expected be paid during 2004. The remaining lease payments are expected to be paid through 2007 unless the leases can be terminated earlier. During 2003, the restructuring reserve was reduced by $2.0 million for cash expenditures and $1.9 million for the settlement of a previously existing contingency. 7. ACQUISITIONS IN JAPAN AND TAIWAN In April 2002, we acquired the semiconductor packaging business of Citizen Watch Co., Ltd. located in the Iwate prefecture in Japan. The purchase price included a $7.8 million cash payment at closing. We were required to make additional payments one year from closing for the amount of the deferred purchase price as well as contingent payments. Based on the resolution of the contingency as of January 2003, the total amount of additional payments due in April 2003 was 1.7 billion Japanese yen. In April 2003, we made a payment of 300.0 million Japanese yen, or $2.5 million based on the exchange rate on the date of the payment. We are withholding payment of 1.4 billion yen ($13.1 million based on the spot exchange rate at December 31, 2003) of this amount pending resolution of a controversy relating to the patents acquired in connection with the acquisition. We recorded $19.6 million of intangible assets for patent rights that are amortizable over 7 years. The fair value of the other assets acquired and liabilities assumed was approximately $2.5 million for fixed assets, $0.1 million for inventory and other assets and $14.2 million for the deferred purchase price payment and minimum amount of the contingent payments. Such net assets principally relate to our packaging services reporting unit. In January 2002, we acquired Agilent Technologies, Inc.'s packaging business related to semiconductor packages utilized in printers for $2.8 million in cash. The purchase price was principally allocated to the tangible assets of our packaging services reporting unit. Our results of operations were not significantly impacted by this acquisition. 62

In July 2001, we acquired, in separate transactions, 69% of Taiwan Semiconductor Technology Corporation ("TSTC") and Sampo Semiconductor Corporation ("Sampo") in Taiwan. Including our prior ownership interest in TSTC, our ownership increased to 94% of the outstanding shares of TSTC. The combined purchase price was paid with the issuance of 4.9 million shares of our common stock valued at $87.9 million based on our closing share price two days prior to each acquisition, the assumption of $34.8 million of debt and $3.7 million of cash consideration, net of acquired cash. We recorded intangible assets, principally goodwill, of $23.8 million as of the acquisition date that is nonamortizable. In connection with earn-out provisions that provided for additional purchase price based in part on the results of the acquisitions, we issued an additional 1.8 million shares in January 2002 and recorded an additional $35.2 million in goodwill. In January 2001, Amkor Iwate Corporation commenced operations and acquired from Toshiba a packaging and test facility located in the Iwate prefecture in Japan. We owned 60% of Amkor Iwate and Toshiba owned the balance of the outstanding shares. At December 31, 2003, our minority interest in Amkor Iwate of $11.8 million was recorded as a liability in accrued expenses, in accordance with SFAS No. 150. In January 2004, we acquired the remaining 40% ownership interest of Amkor Iwate from Toshiba for approximately 1.4 billion Japanese yen ($12.8 million based on the spot exchange rate at December 31, 2003). Also in January 2004, we paid to Toshiba 220.0 million Japanese yen (or $2.0 million based on the spot exchange rate at December 31, 2003) to terminate our commitment to purchase a tract of land adjacent to the Amkor Iwate facility. A $2.0 million charge was recorded in special charges (see Note 3) during the fourth quarter of 2003 related to this termination fee. Amkor Iwate provides packaging and test services principally to Toshiba's Iwate factory under a long-term supply agreement that provides for services to be performed on a cost plus basis through December 2003 and then at market based rates beginning January 2004. This long-term supply agreement with Toshiba's Iwate factory terminates January 2006. The results of our acquisitions have been included in the accompanying consolidated financial statements since their respective acquisition dates. 8. OUR RELATIONSHIP WITH ANAM SEMICONDUCTOR, INC. (ASI) AND INVESTMENT IN ASI OUR RELATIONSHIP WITH ASI We have had a long-standing relationship with ASI. ASI was founded in 1956 by Mr. H. S. Kim, the father of Mr. James Kim, our Chairman and Chief Executive Officer. Through former supply agreements with ASI, we historically subcontracted for packaging and test services which were sourced from ASI's factories in Korea. Beginning in May 2000, with the completion of our acquisitions of ASI's packaging and test facilities, we no longer receive packaging and test services from ASI. In connection with the acquisition of these factories, we committed to making equity investments in ASI, and as a result, accumulated a 42% ownership interest in ASI. Under the former wafer fabrication services supply agreement, we purchased the wafer output of ASI's wafer fabrication facility. Beginning in February 2003, when we sold our wafer fabrication services business to ASI, we no longer purchase ASI's wafer output. In addition, we have had other relationships with ASI affiliated companies for construction services and equipment. We believe each of these transactions was conducted on an arms-length basis in the ordinary course of business. Total purchases from ASI and its affiliates for the years ended December 31, 2003, 2002 and 2001 were $31.1 million, $212.6 million and $161.6 million. Construction services and equipment purchases received from ASI and its affiliates capitalized during the years ended December 31, 2002 and 2001 were $2.8 million and $14.7 million, respectively. We received less than $0.1 million of construction services from ASI and its affiliates during 2003. OUR INVESTMENT IN ASI We evaluate our investments for impairment due to declines in market value that are considered other than temporary. In the event of a determination that a decline in market value is other than temporary, a charge to earnings is recorded for the unrealized loss, and a new cost basis in the investment is established. The stock prices of semiconductor companies' stocks, including ASI and its competitors, have experienced significant volatility during the past several years. The most recent downturn in the semiconductor industry affected the demand for the wafer output from ASI's foundry and the market value of ASI's stock as traded on the Korea Stock Exchange. As a result, we recorded $172.5 million of impairment charges during 2002 to reduce the carrying value of our investment in ASI to ASI's market value. At January 1, 2001 and 2002 Amkor owned 42% of ASI's voting stock. During 2002, we divested 21 million shares of ASI stock and at December 31, 2002, Amkor owned 26.7 million shares of ASI or 21%. The carrying value of our investment in ASI at December 31, 2002 63

was $77.5 million, or $2.90 per share. As discussed further below, on March 24, 2003 we sold 7 million shares of ASI common stock. Beginning on this date we ceased accounting for our investment in ASI under the equity method of accounting and commenced accounting for our investment as a marketable security that is available for sale. As of December 31, 2003, we owned 14.7 million shares of ASI, or 12% of ASI's voting stock. The carrying value of our remaining investment in ASI at December 31, 2003, including an unrealized gain of $10.0, was $50.4 million, or $3.43 per share. We intend to sell our remaining investment in ASI. The ultimate level of proceeds from the sale of our remaining investment in ASI could be less than the current carrying value. As part of our strategy to sell our investment in ASI and to divest our wafer fabrication services business (see Note 2), we entered into a series of transactions beginning in the second half of 2002: - - In September 2002, we sold 20 million shares of ASI common stock to Dongbu Group in exchange for 5700 Korean won per share, the market value of ASI common stock as traded on the Korean Stock Exchange at the time we entered into the share sale agreement. We received $58.1 million in net cash proceeds and 42 billion won (approximately $34.2 million based on the spot exchange rate on the closing date) of interest bearing notes from Dongbu Corporation payable in two equal principal payments in September 2003 and February 2004. The Dongbu Group comprises Dongbu Corporation, Dongbu Fire Insurance Co., Ltd. and Dongbu Life Insurance Co., Ltd., all of which are Korean corporations and are collectively referred to herein as "Dongbu." Associated with this transaction, we recorded a $1.8 million loss. Additionally, we divested one million shares of ASI common stock in connection with the payment of certain advisory fees related to this transaction. On September 30, 2003, we received 21 billion won (approximately $18.3 million based on the September 30, 2003 spot exchange rate), consisting of the principal amount due under the notes from Dongbu. - - In separate transactions designed to facilitate a future merger between ASI and Dongbu, (i) we acquired a 10% interest in Acqutek from ASI for $1.9 million, the market value of the shares as publicly traded in Korea; (ii) we acquired the Precision Machine Division ("PMD") of Anam Instruments, a related party to Amkor, for $8 million, its fair value; and (iii) Anam Instruments, which had been partially owned by ASI, utilized the proceeds from the sale of PMD to us to buy back all of the Anam Instruments shares owned by ASI. Acqutek supplies materials to the semiconductor industry and is publicly traded in Korea. An entity controlled by the family of James Kim, our Chairman and Chief Executive Officer, held a 25% ownership interest in Acqutek at the time of our acquisition of our interest in Acqutek. We have historically purchased and continue to purchase leadframes from Acqutek. On September 17, 2003, we sold our entire ownership interest in Acqutek (see Note 12). PMD supplies sophisticated die mold systems and tooling to the semiconductor industry and historically over 90% of its sales were to Amkor. We determined the fair value of PMD based on projected cash flows discounted at a rate commensurate with the risk involved. At the time of our acquisition of PMD, Anam Instruments was owned 20% by ASI and 20% by a family member of James Kim. - - On February 28, 2003, we sold our wafer fabrication services business to ASI for $62 million. We negotiated the fair value of our wafer fabrication services business with ASI and Dongbu. The parties calculated fair value based on an assessment of projected cash flows discounted at a rate commensurate with the risk involved. We obtained a release from Texas Instruments regarding our contractual obligations with respect to wafer fabrication services to be performed subsequent to the transfer of the business to ASI. Each of the transactions with Dongbu, ASI and Anam Instruments are interrelated and it is possible that if each of the transactions were viewed on a stand-alone basis without regard to the other transactions, we could have had different conclusions as to fair value. It is likely that we would not have entered into the Acqutek or PMD transactions absent the share sale to Dongbu and the sale of the wafer fabrication services business to ASI. Had these transactions not been interrelated, we may have utilized a different negotiation strategy for the investment in Acqutek and the acquisition of PMD, which could have resulted in us reaching a different conclusion of the fair value of both of these transactions. Pursuant to the definitive agreements, (1) Amkor and Dongbu agreed to use reasonable best efforts to cause Dongbu Electronics and ASI to be merged together as soon as practicable, (2) Amkor and Dongbu agreed to cause ASI to use the proceeds ASI received from its sale of stock to Dongbu to purchase shares in Dongbu Electronics and (3) Amkor and Dongbu agreed to use their best efforts to provide releases and indemnifications to the chairman, directors and officers of ASI, either past or incumbent, from any and all liabilities arising out of the performance of their duties at ASI between January 1, 1995 and December 31, 2001. The last provision would provide a release and indemnification for James Kim, our CEO and Chairman, and members of his family. We are not aware of any claims or other liabilities which these individuals would be released from or for which they would receive indemnification. 64

Subsequent to the sale of a portion of our investment in ASI to Dongbu in 2002, we were unable to identify another strategic buyer. ASI's common stock, which is listed on the Korean Stock Exchange, is relatively thinly traded and subject to volatile swings in daily trading volumes. In an effort to continue to monetize our investment in ASI's common stock, we evaluated, in consultation with a financial institution, the most efficient method to divest a large block of shares into the market without destabilizing the share price of ASI's common stock. On March 24, 2003, we consummated a series of transactions proposed by a financial institution. We irrevocably sold a block of 7 million shares of ASI common stock to the financial institution for approximately $19.5 million, or $2.81 per share. We also entered into a nondeliverable call option with the financial institution for $6.8 million, the fair value of the option at that date plus the transaction costs. In May 2003, we exercised the nondeliverable call option realizing $5.6 million of cash proceeds. Accordingly, during 2003 we recorded a loss of $1.2 million related to this nondeliverable call option. On September 17, 2003, we sold an additional 5 million shares of ASI common stock to the same financial institution for approximately $18.5 million, or $3.69 per share, and recorded an associated gain of $4.7 million. We also entered into a nondeliverable call option with the financial institution for $6.5 million, the fair value of the option at that date plus the transaction costs. In December 2003, we exercised the nondeliverable call option realizing $2.0 million of cash proceeds. Accordingly, during 2003 we recorded a loss of $4.5 million related to this nondeliverable call option. The March and September 2003 call options discussed above allowed us to continue to monetize our investment in ASI at a fixed price with unlimited upside and limited downside economics. In addition, it provided us with the economic benefits of selling shares through a dollar averaging sales program without incurring the transaction costs associated with multiple small quantity sales. The call premiums provided the financial institution some downward protection if the market for ASI's common stock destabilized as it sold its investment in ASI's common stock into the market. All ownership rights and privileges associated with the 12 million shares of ASI's common stock sold during 2003 were irrevocably transferred to the financial institution. In no event could the financial institution have put the shares back to Amkor nor was there a provision in the agreements for Amkor to reacquire the shares. FINANCIAL INFORMATION FOR ASI The following summary of consolidated financial information was derived from the consolidated financial statements of ASI. As discussed above, on March 24, 2003, we ceased accounting for our investment in ASI under the equity method of accounting and commenced accounting for our investment as a marketable security that is available for sale. Accordingly, summary consolidated financial information related to ASI is only presented for the periods in which ASI was a significant equity investment: FOR THE YEAR ENDED DECEMBER 31, ------------------------------- 2002 2001 ------------- ------------- (IN THOUSANDS) SUMMARY INCOME STATEMENT INFORMATION FOR ASI Net revenues.......................................... $ 213,813 $ 161,700 Gross profit (loss)...................................

Such impairment charge principally related to machinery and equipment. As discussed in Note 1, beginning July 1, 2003, we consolidate certain Philippine realty corporations in which we have a 40% ownership and from whom we lease land and buildings in the Philippines. Gross value of land and buildings related to these Philippine realty corporations at December 31, 2003 are $15.2 million and $10.8 million, respectively. 11.

ASI was previously accounted for as an equity investment through March 24, 2003 (see Note 8). In connection with the disposition of a portion of our interest in ASI, we acquired a 10% interest in Acqutek from ASI for a total purchase price of $1.9 million (see Note 8). Our investment in Acqutek was classified as a marketable security available for sale at December 31, 2002. In September 2003, our investment in Acqutek was sold at a loss of $0.3 million. Previous to the sale of Acqutek, we recorded during the second quarter of 2003 a $0.9 million charge to earnings to reflect the decline in market value of Acqutek, which was considered to be other than temporary. Total purchases from Acqutek included in cost of revenue for 2003, 2002 and 2001 were $16.1 million, $16.0 million and $14.0 million, respectively, which we believe were conducted on an arms-length basis in the ordinary course of business. In November 2003, we sold our investment in an intellectual property company which was classified as available for sale. This investment was sold for $9.8 million and we recorded an associated gain of $7.3 million in other (income) expense, net. Equity investment losses, as recorded in our consolidated statements of income, are comprised of the following: FOR THE YEAR ENDED DECEMBER 31, ----------------------------------- 2003 2002 2001 --------- --------- --------- (IN THOUSANDS) Equity in loss of investees ........................... $ (3,290) $ (33,865) $(100,706) Loss on impairment of equity investment (see Note 8) .. -- (172,533) -- Loss on equity investment (see Note 8) ................ -- (1,767) -- --------- --------- --------- $ (3,290) $(208,165) $(100,706) ========= ========= ========= 13.

(28,665) (71,023) ----------- ----------- $ 1,650,707 $ 1,737,690 =========== =========== On April 22, 2003, we entered into a new $200.0 million senior secured credit facility consisting of a $170.0 million term loan maturing January 31, 2006 and a $30.0 million revolving line of credit that is available through October 31, 2005. The term loan principal repayments are due $1.7 million, $125.4 million and $41.6 million in 2004, 2005 and 2006, respectively. In addition, the term loan includes certain financial covenants including, but not limited to, minimum EBITDA, as defined by the credit facility, minimum daily liquidity and maximum annual capital expenditures. A default under one debt instrument may also trigger cross-defaults under our other debt instruments. This new credit facility replaced the previous $196.9 million secured credit facility, which included a $96.9 million term loan and a $100.0 million revolving credit facility that were scheduled to mature September 30, 2005 and March 31, 2005, respectively. The funds available under this new credit facility were used to repay the $96.9 million term loan outstanding under the existing credit facility and for general corporate purposes. In connection with the redemption of our term loan, we recorded a charge of $2.4 million during the second quarter of 2003 for the associated unamortized deferred debt issuance costs. In May 2003, we sold $425.0 million of 7.75% senior notes due May 2013 ("original notes"). We sold these notes to qualified institutional investors and used the net proceeds of the issuance to redeem our outstanding 9.25% senior notes due 2006. The notes have a coupon rate of 7.75 % annually and interest payments are due semi-annually. In connection with the redemption, we recorded charges during the second quarter of 2003 of $19.7 million related to the premium paid to redeem these notes, $6.0 million for the associated unamortized deferred debt issuance costs and $2.5 million of other costs. In connection with the original notes, we entered into a registration rights agreement with the initial purchasers of the original notes. In the exchange offer, the original note holders were entitled to exchange their original notes for exchange notes ("exchange notes"), with substantially identical terms as the original notes. In July 2003, we filed a Form S-4 Registration Statement with the Securities and Exchange Commission to effect this exchange offer which became effective October 22, 2003. During 2003, we received board of director approval to purchase up to $150.0 million of the 9.25% senior notes due 2008, and we have been purchasing these notes in the open market. As of December 31, 2003, we purchased $29.5 million of the 9.25% senior notes due 2008 for which we recognized a loss on this retirement of debt of $1.6 million and a charge of $0.4 million for the associated unamortized deferred debt issuance costs during 2003. In November 2003, we repurchased $112.3 million of our 5.00% convertible subordinated notes due March 2007 and $17.0 million of our 5.75% convertible subordinated notes due June 2006. In connection with the redemption of these convertible notes, we recorded charges during the fourth quarter of 2003 of $2.8 million related to premiums paid to redeem these notes and $2.3 million for the associated unamortized deferred debt issuance costs. 68

Other debt as of December 31, 2003 and 2002 includes our foreign debt principally related to the financing of Amkor Iwate's acquisition of a Toshiba packaging and test facility and the debt assumed in connection with the acquisition of Sampo Semiconductor Corporation in Taiwan. Our foreign debt includes fixed and variable debt maturing between 2003 and 2010, with the substantial majority maturing by 2003. As of December 31, 2003, the foreign debt has interest rates ranging from 1.0% to 4.35%. These debt instruments do not include significant financial covenants. Interest expense related to short-term borrowings and long term debt is presented net of interest income of $5.9 million, $4.2 million and $10.3 million for 2003, 2002 and 2001, respectively, in the accompanying consolidated statements of income. The principal payments required under short-term and long-term debt borrowings at December 31, 2003 are as follows: 2004 -- $28.7 million, 2005 -- $129.0 million, 2006 -- $277.5 million, 2007 -- $147.2 million, 2008 -- $471.1 million and thereafter -- $625.9 million. 15. STOCKHOLDERS' EQUITY In connection with a $410.0 million private equity offering in May 2000, we issued 20.5 million shares of our common stock and granted warrants that expire four years from issuance to purchase 3.9 million additional shares of our common stock at $27.50 per share. None of these warrants have been exercised to date. The estimated fair value of the stock warrants of $35.0 million is included in additional paid-in capital on our consolidated balance sheet. In November 2003, we sold 7.4 million shares of our common stock for net proceeds of $133.5 million. These net proceeds were used to repurchase $112.3 million of our 5.00% convertible notes due 2007 and $17.0 million of our 5.75% convertible notes due 2006. In September 2003, a receivable due to us of $2.9 million was collected in full. This receivable was previously reflected as a receivable from stockholders in the stockholders' equity section of our balance sheet (see Note 1). 16. EMPLOYEE BENEFIT PLANS U.S. Defined Contribution Plan Our company has a defined contribution benefit plan covering substantially all U.S. employees. Employees can contribute up to the lesser of 60% of salary or $12,000 annually to the plan. The company matches in cash 75% of the employee's contributions up to a defined maximum on an annual basis. The expense for this plan was $1.7 million, $2.0 million and $2.1 million in 2003, 2002 and 2001, respectively. Philippine Pension Plan Our Philippine subsidiary sponsors a defined benefit plan that covers substantially all employees who are not covered by statutory plans. Charges to expense are based upon costs computed by independent actuaries. The components of net periodic pension cost for the Philippine defined benefit plan are as follows: YEAR ENDED DECEMBER 31, ----------------------------- 2003 2002 2001 ------- ------- ------- (IN THOUSANDS) Service cost of current period ................... $ 2,343 $ 2,339 $ 2,534 Interest cost on projected benefit obligation .... 1,412 1,681 1,919 Expected return on plan assets ...................

DECEMBER 31, ------------------------------- 2003 2002 ------------- ------------- (IN THOUSANDS) Deferred tax assets: Net operating loss carryforwards...................... $ 167,747 $ 160,043 Investments........................................... 41,992 81,103 Capital loss carryover................................ 84,038 45,069 Inventories........................................... 8,326 7,945 Corporate income tax credits.......................... 2,259 5,447 Accounts receivable................................... 2,688 3,605 Property, plant and equipment......................... 11,751 3,594 Goodwill.............................................. 3,641 4,023 Other accrued liabilities............................. 4,645 2,790 Unrealized foreign exchange losses.................... 935 1,054 Loss on impairment/lease shutdown reserves............ 7,748 11,890 Other................................................. 5,667 6,666 ------------- ------------- Total deferred tax assets................................ 341,437 333,229 Valuation allowance......................................

In connection with our divestiture in 2003 of 12 million shares of ASI common stock and other investments, we recognized a capital loss of approximately $80.6 million and recognized a U.S. tax benefit of $32.2 million for which we provided a full valuation allowance because we did not have any offsetting capital gains. In connection with our divestiture in 2002 of 21 million shares of ASI common stock, we realized a capital loss of approximately $117.0 million and recognized a U.S. tax benefit of $44.5 million for which we provided a full valuation allowance because we did not have any offsetting capital gains. Generally accepted accounting principles require companies to weigh both positive and negative evidence in determining the need for a valuation allowance. During 2002, in light of our three years of cumulative losses, an unprecedented industry downturn and continued poor visibility of customer demand, we determined that a valuation allowance representing a substantial majority of our deferred tax assets was appropriate. These negative factors outweighed, and continued to outweigh in 2003, our forecasted future profitability and expectation that we will be able to utilize our net operating loss carryforwards. As a result of certain capital investments, export commitments and employment levels, income from operations in Korea, the Philippines and China is subject to reduced tax rates, and in some cases is wholly exempt from taxes. In Korea, we benefit from a tax holiday extending through 2013 that provides for a 100% tax holiday for seven years and then 50% tax holiday for an additional 3 years. In the Philippines, our operating locations operate in economic zones and in exchange for tax holidays we have committed to certain export and employment levels. For 2004 and beyond, certain qualifying Philippine operations will benefit from a one year full tax holiday, subject to extension, while the remaining operations will benefit from a perpetual reduced tax rate of 5%. As a result of our 2001 investment in China, we expect to benefit from a 100% tax holiday for five years and then 50% tax holiday for an additional two years. As a result of the net losses incurred by our foreign subsidiaries subject to tax holidays during 2003, 2002 and 2001, there is a forgone income tax benefit attributable to the tax status of these subsidiaries of approximately $4.8 million, or $0.03 per share, $63.3 million, or $0.39 per share and $33.8 million, or $0.21 per share in 2003, 2002 and 2001, respectively. 73

In December 2002, we utilized $33.3 million of U.S. net operating losses by carrying back such amounts to offset U.S. reported taxable income in prior years. At December 31, 2003, we have remaining U.S. net operating losses available to be carried forward totaling $404.9 million expiring between 2021 and 2023. Additionally, at December 31, 2003, we had non-U.S. net operating losses available to be carried forward totaling $49.1 million expiring between 2004 and 2013. Non-U.S. income (loss) before taxes and minority interest was $53.4 million, ($395.3) million and ($180.7) million in 2003, 2002 and 2001, respectively. At December 31, 2003 and 2002, net cumulative undistributed losses of non-U.S. subsidiaries totaled approximately $8.1 million and $61.4 million, respectively. No liabilities are recognized for our cumulative earnings loss position and no U.S. income and foreign withholding taxes would be due on the cumulative earnings loss. It is the company's intention to reinvest any undistributed earnings outside the U.S. At December 31, 2003 and 2002 current deferred tax assets of $2.3 million and $5.5 million, respectively, are included in other current assets and noncurrent deferred tax assets of $28.5 million and $36.3 million, respectively, are included in other assets in the consolidated balance sheet. The net deferred tax assets include amounts, which, in our opinion, are more likely than not to be realizable through future taxable income. In addition, at December 31, 2003 and 2002, noncurrent deferred tax liabilities of $1.5 million and $4.6 million, respectively, are included in other noncurrent liabilities in the consolidated balance sheet. We operate in and file income tax returns in various U.S. and non-U.S. jurisdictions which are subject to examination by tax authorities. For our larger operations, our tax returns have been examined through 1998 in the Philippines and the U.S. and through 2000 in Japan and Taiwan. The tax returns for open years in all jurisdictions in which we do business are subject to changes upon examination. During 2003, the Internal Revenue Service commenced an examination related to years 2001 and 2000. We believe that we have estimated and provided adequate accruals for the probable additional taxes and related interest expense that may ultimately result from examinations related to our transfer pricing and local attribution of income resulting from significant intercompany transactions, including ownership and use of intellectual property, in various U.S. and non-U.S. jurisdictions. Our estimated tax liability is subject to change as examinations of specific tax years are completed in the respective jurisdictions. We believe that any additional taxes or related interest over the amounts accrued will not have a material effect on our financial condition or results of operations, nor do we expect that examinations to be completed in the near term would have a material favorable impact. During 2003, we reduced tax accruals by $20.0 million related to tax periods no longer open. As of December 31, 2003 and 2002, the accrual for current taxes and estimated additional taxes was $39.8 million and $48.8 million, respectively. In addition, changes in the mix of income from our foreign subsidiaries, expiration of tax holidays and changes in tax laws or regulations could result in increased effective tax rates in the future. 18. EARNINGS PER SHARE Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share," requires dual presentation of basic and diluted earnings per share on the face of the income statement. Basic EPS is computed using only the weighted average number of common shares outstanding for the period, while diluted EPS is computed assuming conversion of all dilutive securities, such as options, convertible debt and warrants. For the years ended December 31, 2003, 2002 and 2001, we excluded from the computation of diluted earnings per share potentially dilutive securities which would have an antidilutive effect on EPS. As of December 31, 2003, the total number of potentially dilutive securities outstanding was 15.8 million, 9.2 million and 3.9 million for outstanding options, convertible notes and warrants for common stock, respectively. As of December 31, 2002, the total number of potentially dilutive securities outstanding was 6.6 million, 11.7 million and 3.9 million for outstanding options, convertible notes and warrants for common stock, respectively. As of December 31, 2001, the total number of potentially dilutive securities outstanding was 12.4 million, 11.7 million and 3.9 million for outstanding options, convertible notes and warrants for common stock, respectively. The basic and diluted per share amounts are the same for the years 2003, 2002 and 2001 due to net losses from continuing operations. 19. STOCK COMPENSATION PLANS 1998 Director Option Plan. A total of 300,000 shares of common stock have been reserved for issuance under the Director Plan. The option grants under the Director Plan are automatic and non-discretionary. As of January 1, 2003, the Director Plan provides for an initial grant of options to purchase 20,000 shares of common stock to each new non-employee director of the company when such individual first becomes an outside director. In addition, each non-employee director will automatically be granted subsequent options to purchase 10,000 shares of common stock on each date on which such director 74

is re-elected by the stockholders of the company, provided that as of such date such director has served on the board of directors for at least six months. The exercise price of the options is 100% of the fair market value of the common stock on the grant date. The term of each option is ten years and each option granted to an non-employee director vests over a three year period. The Director Plan will terminate in January 2008 unless sooner terminated by the board of directors. 1998 Stock Plan. The 1998 Stock Plan generally provides for the grant to employees, directors and consultants of stock options and stock purchase rights. Unless terminated sooner, the 1998 Plan will terminate automatically in January 2008. A total of 5,000,000 shares are available for issuance under the 1998 Stock Plan, and there is a provision for an annual replenishment to bring the number of shares of common stock reserved for issuance under the plan up to 5,000,000 as of each January 1. Unless determined otherwise by the board of directors or a committee appointed by the board of directors, options and stock purchase rights granted under the 1998 Plan are not transferable by the optionee. Generally, the exercise price of all stock options granted under the 1998 Plan must be at least equal to the fair market value of the shares on the date of grant. In general, the options granted will vest over a four year period and the term of the options granted under the 1998 Plan may not exceed ten years. On November 8, 2002, we initiated a voluntary stock option replacement program such that employees and members of our board of directors could elect to surrender their existing options and be granted new options no earlier than six months and one day after the tendered options were cancelled. Pursuant to the terms and conditions of the offer to exchange, a total of 1,633 eligible employees participated. On June 16, 2003, we granted 6,978,563 shares of our common stock under the 1998 Stock Plan and 35,000 shares of our common stock under the 1998 Director Option Plan for the options tendered by eligible employees and members of our board of directors and accepted by our company. For options that were granted under the previously existing 1998 French Plan, which was terminated in April 2003, and that were surrendered pursuant to voluntary stock option replacement program, we granted an additional 248,200 replacement options under the 1998 Stock Plan. We have issued new option grants equal to the same number of shares surrendered by the employees. The exercise price of the new options was $10.79, which was equal to the fair market value of our stock price on the date of grant. The vesting term of these new options are similar to the tendered options except the new options contain an additional one-year vesting period prior to any options becoming exercisable. 2003 Nonstatutory Inducement Grant Stock Plan. On September 9, 2003, we initiated the 2003 Nonstatutory Inducement Grant Stock Plan (the "2003 Plan"). The 2003 Plan generally provides for the grant to employees, directors and consultants of stock options and stock purchase rights and is generally used as an inducement benefit for the purpose of retaining new employees. The 2003 Plan terminates at the discretion of the Board of Directors. As of December 31, 2003, a total of 300,000 shares were reserved for issuance under the 2003 Stock Plan and there is a provision for an annual replenishment to bring the number of shares of common stock reserved for issuance under the plan up to 300,000. A summary of the status of the stock option plans follows: WEIGHTED AVERAGE WEIGHTED AVERAGE NUMBER EXERCISE PRICE GRANT DATE OF SHARES PER SHARE FAIR VALUES ------------- ---------------- ---------------- Balance at December 31, 2000............ 9,270,201 $ 25.48 Granted................................. 4,313,850 15.14 $ 8.47 =========== Exercised............................... 517,822 9.88 Cancelled............................... 709,863 27.60 ------------- ----------- Balance at December 31, 2001............ 12,356,366 22.40 Granted................................. 4,004,460 12.76 $ 7.94 =========== Exercised............................... 547,862 10.30 Cancelled............................... 9,239,701 24.88 ------------- ----------- Balance at December 31, 2002............ 6,573,263 14.15 Granted................................. 11,406,399 11.29 $ 4.84 =========== Exercised............................... 976,903 10.40 Cancelled............................... 1,213,189 19.81 ------------- ----------- Balance at December 31, 2003............ 15,789,570 $ 11.90 ============= =========== 75

The following assumptions were used to calculate weighted average fair values of the options granted: FOR THE YEAR ENDED DECEMBER 31, ------------------------------- 2003 2002 2001 ---- ---- ---- Expected life (in years) ..... 4 4 4 Risk-free interest rate ...... 2.9% 2.5% 4.5% Volatility ................... 68% 85% 70% Dividend yield ............... -- -- -- 1998 Employee Stock Purchase Plan. A total of 1,000,000 shares of common stock are available for sale under the Stock Purchase Plan and an annual increase is to be added as of each January 1 to restore the maximum aggregate number of shares of common stock available for sale under the plan up to 1,000,000. Employees (including officers and employee directors of the company but excluding 5% or greater stockholders) are eligible to participate if they are customarily employed for at least 20 hours per week. The Stock Purchase Plan permits eligible employees to purchase common stock through payroll deductions, which may not exceed 15% of the compensation an employee receives on each payday. Each participant will be granted an option on the first day of a two year offering period, and shares of common stock will be purchased on four purchase dates within the offering period. The purchase price of the common stock under the Stock Purchase Plan will be equal to 85% of the lesser of the fair market value per share of common stock on the start date of the offering period or on the purchase date. Employees may end their participation in an offering period at any time, and participation ends automatically on termination of employment with the company. The Stock Purchase Plan will terminate in January 2008, unless sooner terminated by the board of directors. For the years ended December 31, 2003, 2002 and 2001, employees purchased common stock shares under the stock purchase plan of 999,827, 996,617 and 482,937, respectively. The average estimated fair values of the purchase rights granted during the years ended December 31, 2003, 2002 and 2001 based on the Black-Scholes option pricing model were $1.70, $3.16 and $6.53, respectively. The following assumptions were used to calculate weighted average fair values of the purchase rights granted: 76

FAIR VALUE OF FINANCIAL INSTRUMENTS The estimated fair value of financial instruments has been determined using available market information and appropriate methodologies; however, considerable judgment is required in interpreting market data to develop the estimates for fair value. Accordingly, these estimates are not necessarily indicative of the amounts that we could realize in a current market exchange. Certain of these financial instruments are with major financial institutions and expose us to market and credit risks and may at times be concentrated with certain counterparties or groups of counterparties. The creditworthiness of counterparties is continually reviewed, and full performance is anticipated. The carrying amounts reported in the balance sheet for due from affiliates, other accounts receivable, due to affiliates, accrued expenses and accrued income taxes approximate fair value due to the short-term nature of these instruments. The methods and assumptions used to estimate the fair value of other significant classes of financial instruments is set forth below: Cash and Cash Equivalents. Cash and cash equivalents are due on demand or carry a maturity date of less than three months when purchased. The carrying amount of these financial instruments is a reasonable estimate of fair value. Available for sale investments. The fair value of these financial instruments was estimated based on market quotes, recent offerings of similar securities, current and projected financial performance of the company and net asset positions. Long-term debt. The carrying amount of our total long-term debt as of December 31, 2003 and 2002 was $1,650.7 million and $1,737.7, respectively. The fair value of our total long-term debt as of December 31, 2003 and 2002, based on available market quotes, was estimated to be $1,754.2 million and $1,321.3 million, respectively. 21. COMMITMENTS AND CONTINGENCIES Amkor is involved in various claims incidental to the conduct of our business. Based on consultation with legal counsel, we do not believe that any claims, either individually or in the aggregate, to which the company is a party will have a material adverse effect on our financial condition or results of operations. Net future minimum lease payments under operating leases that have initial or remaining noncancelable lease terms in excess of one year are: DECEMBER 31, 2003 ------------- (IN THOUSANDS) 2004 ....................................................... $ 10,935 2005 ....................................................... 7,739 2006 ....................................................... 8,499 2007 ....................................................... 8,276 2008 ....................................................... 8,388 Thereafter ................................................. 89,987 ------------- Total (net of minimum sublease income of $5,094) .... $ 133,824 ============= Rent expense amounted to $16.4 million, $15.0 million and $21.8 million for 2003, 2002 and 2001, respectively. We lease office space in West Chester, Pennsylvania from certain of our stockholders. The lease expires in 2006. We have the option to extend the lease for an additional 10 years through 2016. Amounts paid for this lease in 2003, 2002 and 2001 were 77

$1.1 million, $1.2 million and $1.2 million, respectively. Our sublease income includes $0.5 million in each of the three years ended December 31, 2003 from a company in which certain related parties have ownership interests. INDEMNIFICATIONS AND GUARANTEES We have indemnified members of our board of directors and our corporate officers against any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that the Indemnitee is or was a director or officer of the company. The indemnities are indemnified, to the fullest extent permitted by law, against related expenses, judgments, fines and any amounts paid in settlement. We also maintain Directors and Officers insurance coverage in order to mitigate our exposure to these indemnification obligations. The maximum amount of future payments is generally unlimited. There is no amount recorded for this indemnification at December 31, 2003. Due to the nature of this indemnification, it is not possible to make a reasonable estimate of the maximum potential loss or range of loss. No assets are held as collateral and no specific recourse provisions exist related to this indemnification. As of December 31, 2003, we have outstanding $2.2 million of standby letters of credit. Such standby letters of credit are used in our ordinary course of business and are collateralized by our cash balances. We generally provide a standard ninety-day warranty on our services. Our warranty activity has historically been immaterial and is expected to continue to be immaterial in the foreseeable future. LITIGATION We are currently a party to various legal proceedings, including those noted below. While we currently believe that the ultimate outcome of these proceedings, individually and in the aggregate, will not have a material adverse effect on our financial position or overall trends in results of operations, litigation is subject to inherent uncertainties. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on our net income in the period in which the ruling occurs. The estimate of the potential impact from the following legal proceedings on our financial position or overall results of operations could change in the future. EPOXY MOLD COMPOUND LITIGATION Recently, we have become party to an increased number of litigation matters relative to our historic levels. Much of our recent increase in litigation relates to an allegedly defective epoxy mold compound, formerly used in some of our products, which is alleged to be responsible for certain semiconductor chip failures. In the case of each of these matters, we believe we have meritorious defenses, as well as valid third-party claims against Sumitomo Bakelite Co., Ltd. ("Sumitomo Bakelite"), the manufacturer of the challenged epoxy product, should the epoxy mold compound be found to be defective. We cannot be certain, however, that we will be able to recover any amount from Sumitomo Bakelite if we are held liable in these matters, or that any adverse result would not have a material impact upon us. Moreover, other customers of ours have made inquiries about the epoxy mold compound, which was widely used in the semiconductor industry, and no assurance can be given that claims similar to those already asserted will not be made against us by other customers in the future. Fujitsu Limited v. Cirrus Logic, Inc., et al. On April 16, 2002, we were served with a third-party complaint in an action entitled Fujitsu Limited v. Cirrus Logic, Inc., No. 02-CV-01627 JW, pending in the United States District Court for the Northern District of California, San Jose Division. In this action, Fujitsu Limited ("Fujitsu") alleges that semiconductor devices it purchased from Cirrus Logic, Inc. ("Cirrus Logic") are defective in that a certain epoxy mold compound used in the manufacture of the chip causes a short circuit which renders Fujitsu disk drive products inoperable. Cirrus Logic, in response, denied the allegations of the complaint, counterclaimed against Fujitsu for unpaid invoices, and filed its third-party complaint against us alleging that any liability for chip defects should be assigned to us because we assembled the subject semiconductor devices. Upon receipt of Cirrus Logic's third-party complaint, we filed an answer denying all liability, and our own third-party complaint against Sumitomo Bakelite. Sumitomo Bakelite filed an answer denying liability. In June 2003, Fujitsu amended its complaint and added direct claims against us. In response, we filed an answer denying all liability to Fujitsu. Fujitsu has indicated that it may seek damages in excess of $100 million. Discovery is ongoing and a trial is currently scheduled to begin in the Northern District Court of California on January 31, 2005. In November 2003, Fujitsu filed an action against Cirrus Logic, Sumitomo 78

Bakelite and us entitled Fujitsu Limited v. Cirrus Logic, Inc., et al., No. 1-03-CV-009885, in the California Superior Court for the County of Santa Clara, based on facts and allegations substantially similar to those asserted in the Northern District Court of California. In December 2003, Cirrus Logic filed a cross-complaint against Sumitomo Bakelite and us in the Superior Court case, also based on facts and allegations substantially similar to those asserted in the Northern District Court case. By stipulation among the parties, Fujitsu and Cirrus Logic have stated their intent to stay the action pending in the Northern District Court of California in favor of the action pending in the Santa Clara Superior Court. Trial in the Superior Court action is currently scheduled to begin on January 31, 2005. Amkor intends to deny all liability, to file cross-claims against Sumitomo Bakelite, and to seek dismissal of all claims against it in due course. Seagate Technology LLC v. Atmel Corporation, et al. In March 2003, we were served with a cross-complaint in an action between Seagate Technology LLC ("Seagate") and Atmel Corporation ("Atmel") in the Superior Court of California, Santa Clara County. Atmel's cross-complaint seeks indemnification from us for any damages incurred from the claims by Seagate involving the allegedly defective epoxy mold compound manufactured by Sumitomo Bakelite. We have answered Atmel's cross-complaint, denying all liability, and have filed a cross-complaint against Sumitomo Bakelite. Atmel later amended its cross-complaint, including adding ChipPAC Inc. ("ChipPAC") as a cross-defendant. ChipPAC filed a cross-complaint against Sumitomo Bakelite and us. On January 27, 2004, the Superior Court sustained Sumitomo Bakelite's motion to dismiss Atmel's cross-complaint, granting Atmel 30 days to file an amended pleading. We filed a motion to dismiss ChipPAC's cross-complaint on February 13, 2004, and otherwise intend to deny all liability to ChipPAC. We also intend to deny all liability to Atmel and may seek the dismissal of Atmel's further amended cross-complaint upon receipt, if appropriate. All parties are currently conducting discovery and no trial date has been set. Maxtor Corporation v. Koninklijke Philips Electronics N.V., et al. In April 2003, we were served with a cross-complaint in an action between Maxtor Corporation ("Maxtor") and Koninklijke Philips Electronics ("Philips"). Philips' cross-complaint seeks indemnification from us for any damages incurred from the claims by Maxtor involving the allegedly defective epoxy mold compound manufactured by Sumitomo Bakelite. Philips subsequently filed a cross-complaint directly against Sumitomo Bakelite, alleging, among other things, that Sumitomo Bakelite breached its contractual obligations to both us and Philips by supplying a defective mold compound resulting in the failure of certain Philips semiconductor devices. We have denied all liability in this matter and have also asserted a cross-complaint against Sumitomo Bakelite. Sumitomo Bakelite has denied any liability. The parties' discovery efforts are ongoing, including expert discovery. In December 2003, we filed a motion for summary judgment against Philips's cross-claims. The motion shall be heard March 30, 2004. The trial is scheduled to start on April 12, 2004. Maxim Integrated Products, Inc. v. Amkor Technology, Inc., et al. In August 2003, we were served with a complaint filed by Maxim Integrated Products, Inc. ("Maxim") against us, Sumitomo Bakelite and Sumitomo Plastics America, Inc. ("Sumitomo Plastics") in the Superior Court of California, Santa Clara County. The complaint seeks damages related to our use of Sumitomo Bakelite's epoxy mold compound in assembling Maxim's semiconductor packages. Both the Sumitomo defendants and we filed motions to dismiss Maxim's complaint in September 2003. In lieu of contesting those motions to dismiss, Maxim has indicated its intent to file an amended pleading. We intend to deny all liability to Maxim and to file cross-claims against Sumitomo Bakelite; we may file another motion to dismiss Maxim's amended complaint upon receipt, if appropriate. Discovery has not commenced and there is no trial date set. Fairchild Semiconductor Corporation v. Sumitomo Bakelite Singapore Pte. Ltd., et al. In September 2003, we were served with an amended complaint filed by Fairchild Semiconductor Corporation ("Fairchild") against us, Sumitomo Bakelite, Sumitomo Plastics and Sumitomo Bakelite Singapore Pte. Ltd. in the Superior Court of California, Santa Clara County. The amended complaint seeks damages related to our use of Sumitomo Bakelite's epoxy mold compound in assembling Fairchild's semiconductor packages. Both the Sumitomo defendants and we filed motions to dismiss Fairchild's amended complaint in October 2003. Fairchild filed a second amended complaint in January 2004. On February 11, 2004, we filed a motion to dismiss Fairchild's second amended complaint. We also intend to deny all liability and to file cross-claims against Sumitomo Bakelite. Discovery is ongoing and no trial date has been scheduled. 79

OTHER LITIGATION On August 16, 2002, we filed a complaint against Motorola, Inc. in an action captioned Amkor Technology, Inc. v. Motorola, Inc., C.A. No. 02C-08-160 CHT, pending in the Superior Court of the State of Delaware in and for New Castle County. In this action, we were seeking declaratory judgment relating to a controversy between us and Motorola concerning: (i) the assignment by Citizen Watch Co., Ltd. ("Citizen") to us of a Patent License Agreement dated January 25, 1996 between Motorola and Citizen (the "License Agreement") and concurrent assignment by Citizen to us of Citizen's interest in U.S. Patents 5,241,133 and 5,216,278 (the "'133 and '278 patents"); and (ii) our obligation to make certain payments pursuant to an immunity agreement (the "Immunity Agreement") dated June 30, 1993 between us and Motorola. We and Motorola resolved the controversy with respect to all issues relating to the Immunity Agreement, and all claims and counterclaims filed by the parties in the case relating to the Immunity Agreement were dismissed or otherwise disposed of without further litigation. The claims relating to the License Agreement and the '133 and '278 Patents remained pending. We and Motorola both filed motions for summary judgment on the remaining claims, and oral arguments were heard on September 3, 2003. On October 6, 2003, the Superior Court of Delaware ruled in favor of us and issued an Opinion and Order granting our motion for summary judgment and denying Motorola's motion for summary judgment. On October 22, 2003, Motorola filed an appeal in Supreme Court of Delaware. We believe we will prevail on the same merits in such appeal. In addition, should Motorola prevail at the appellate level, we believe we have recourse against Citizen. However, no assurance can be given that an adverse outcome in the case cannot occur, or that any adverse outcome would not have a material impact. Alcatel Business Systems vs. Amkor Technology, Inc., Anam Semiconductor, Inc. On November 5, 1999, we agreed to sell certain semiconductor parts to Alcatel Microelectronics, N.V. ("AME"), a subsidiary of Alcatel S.A. The parts were manufactured for us by Anam Semiconductor, Inc. ("ASI"). AME transferred the parts to another Alcatel subsidiary, Alcatel Business Systems ("ABS"), which incorporated the parts into cellular phone products. In early 2001, a dispute arose as to whether the parts sold by us were defective. On March 18, 2002, ABS and its insurer filed suit against us and ASI in the Paris Commercial Court of France, claiming damages of 50 million Euros (approximately $62.8 million based on the spot exchange rate at December 31, 2003). We have denied all liability and intend to vigorously defend ourselves. Additionally, we have entered into a written agreement with ASI whereby ASI has agreed to indemnify us fully against any and all loss related to the claims of AME, ABS and ABS' insurer. The Paris Commercial Court commenced a special proceeding before a technical expert to report on the facts of the dispute. The report of the court-appointed expert was put forth on December 31, 2003. The report does not specifically allocate liability to any particular party. The next proceeding in this matter is expected in April 2004. In response to the lawsuit, on May 22, 2002, we filed a petition to compel arbitration in the United States District Court for the Eastern District of Pennsylvania (the "Court") against ABS, AME and ABS' insurer, claiming that the dispute is subject to the arbitration clause of the November 5, 1999 agreement between us and AME. ABS and ABS' insurer have refused to arbitrate. In August 2003, the Court denied the motion of ABS and its insurer to dismiss our petition for arbitration. The Court also subsequently denied a motion for reconsideration filed by ABS. The Court has not yet set a date for final disposition of our petition. 22. CUSTOMER CONCENTRATIONS AND GEOGRAPHIC INFORMATION With the commencement of operations of Amkor Iwate and the acquisition of a packaging and test facility from Toshiba in 2001, total net revenues derived from Toshiba accounted for 11.6%, 14.7% and 16.3% of our consolidated net revenues for 2003, 2002 and 2001, respectively. Prior to the sale of our wafer fabrication services business to ASI in February 2003, we derived 92.8% and 79.4% of our wafer fabrication revenues from Texas Instruments (TI) for 2002 and 2001, respectively. Effective as of February 28, 2003, we obtained a release from Texas Instruments regarding our contractual obligations with respect to wafer fabrication services to be performed subsequent to the transfer of the business to ASI. We restated our historical results to reflect our wafer fabrication services segment as a discontinued operation (see Note 2). 80

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE Effective September 30, 2003, SyCip Gorres Velayo & Co. ("SGV"), a member practice of Ernst & Young Global, was replaced as external auditors of our wholly owned subsidiary, Amkor Technology Philippines, Inc. ("ATP"). SGV became a member practice of Ernst & Young Global beginning September 1, 2002. SGV was a member firm of Arthur Andersen at the time it provided its report on the combined financial statements of Amkor Technology Philippines (P1/P2), Inc. and Amkor Technology Philippines (P3/P4), Inc., which were the predecessor entities of ATP. PricewaterhouseCoopers LLP, our principal accountant, relied in its report on our consolidated financial statements on SGV's report on the financial statements of ATP as of and for the year ended December 31, 2002 and on SGV's report on the combined financial statements of ATP's predecessor entities as of and for the fiscal years ended December 31, 2001 and 2000. The replacement was approved by the Audit Committee of our board of directors. PricewaterhouseCoopers has expanded the scope of its services to include the audit of ATP for the year ending December 31, 2003. The independent auditors' reports of SGV on the financial statements of ATP or on the combined financial statements of its predecessor entities during the two fiscal years ended December 31, 2002 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the two fiscal years ended December 31, 2002 and through September 30, 2003, we had no disagreements with SGV on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which, if not resolved to the satisfaction of SGV, would have caused it to make a reference to the subject matter of the disagreement in connection with its reports. During the two fiscal years ended December 31, 2002 and through September 30, 2003, there have been no "reportable events" as defined in Item 304(a)(1)(v) of Regulation S-K. We provided SGV with a copy of this disclosure, and we requested that SGV furnish us with a letter addressed to the Securities and Exchange Commission ("SEC"), stating whether it agrees with the above statements. A copy of SGV's letter to the SEC, dated September 30, 2003, is filed as Exhibit 16.1 to this Form 10-K. ITEM 9A. CONTROLS AND PROCEDURES During the fourth quarter of 2003, Amkor management, including the principal executive officer and principal financial officer, evaluated Amkor's disclosure controls and procedures related to the recording, processing, summarization and reporting of information in its periodic reports that Amkor files with the SEC. These disclosure controls and procedures have been designed to ensure that (a) material information relating to Amkor, including its consolidated subsidiaries, is made known to Amkor's management, including these officers, by other employees of Amkor and its subsidiaries, and (b) this information is recorded, processed, summarized, evaluated and reported, as applicable, within the time periods specified in the SEC's rules and forms. Due to the inherent limitations of control systems, not all misstatements may be detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls could be circumvented by the individual acts of some persons or by collusion of two or more people. Amkor's controls and procedures can only provide reasonable, not absolute, assurance that the above objectives have been met. Accordingly, as of December 31, 2003, these officers (principal executive officer and principal financial officer) concluded that Amkor's disclosure controls and procedures were effective to accomplish their objectives. Amkor continually strives to improve its disclosure controls and procedures to enhance the quality of its financial reporting and to maintain dynamic systems that change as conditions warrant. There was no change in our internal control over financial reporting that occurred during the period covered by this Annual Report on Form 10-K that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 85

Further, our Amkor Code of Ethics and our Amkor Directors' Code of Ethics are included as exhibits to this Form 10-K. We intend to disclose any amendments or waivers to our codes of ethics on our website: www.amkor.com. BOARD MEETINGS AND COMMITTEES Our board of directors meets approximately four times a year in regularly scheduled meetings, but will meet more often if necessary. The board of directors held four meetings and acted by unanimous written consent on three occasions during 2003. Each director attended at least 75% of all board and applicable committee meetings. The full board of directors considers all major decisions of Amkor. However, the board of directors has established a compensation committee, an audit committee and a nominating committee. Both the compensation committee and audit committee are chaired by an outside director. COMPENSATION COMMITTEE The Compensation Committee is presently comprised of Messrs. George and Churchill. The Compensation Committee: (1) reviews and approves annual salaries, bonuses, and grants of stock options pursuant to our 1998 Stock Plan and our 2003 Nonstatutory Inducement Grant Stock Plan and (2) reviews and approves the terms and conditions of all employee benefit plans or changes to these plans. During 2003, the Compensation Committee met three times apart from regular meetings with the entire board of directors. THE AUDIT COMMITTEE The Audit Committee is comprised of Messrs. Churchill, Hinckley, Neff and Zug all of whom meet the independence 88

and experience requirements set forth in the Nasdaq rules. The board of directors has determined that three of our four Audit Committee members, Messrs. Hinckley, Neff and Zug, qualify as audit committee financial experts, and are independent, as both are defined by the SEC. The Audit Committee: (1) recommends to the board of directors the annual appointment of our independent auditors, (2) discusses and reviews in advance the scope and the fees of the annual audit, (3) reviews the results of the audit with the independent auditors and discusses the foregoing with the company's management, (4) reviews and approves non-audit services of the independent auditors, (5) reviews the activities, organizational structure and qualifications of the company's internal audit function, (6) reviews management's procedures and policies relating to the adequacy of our internal accounting controls and compliance with applicable laws relating to accounting practices and (7) reviews and discusses with our independent auditors their independence. The Audit Committee met twelve times apart from regular meetings with the entire board. In connection with the execution of the responsibilities of the Audit Committee, including the review of the company's quarterly earnings prior to the public release of the information, the Audit Committee members communicated throughout 2003 with the company's management and independent accountants. COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934 Section 16(a) of the Securities Exchange Act of 1934 requires our officers and directors, and persons who own more than ten percent of a registered class of our equity securities, to file reports of ownership on Form 3 and changes in ownership on Form 4 or 5 with the Securities and Exchange Commission (the "SEC") and the National Association of Securities Dealers, Inc. Such officers, directors and ten-percent stockholders are also required by SEC rules to furnish Amkor with copies of all forms that they file pursuant to Section 16(a). Based solely on our review of the copies of such forms received by us, or written representations from certain reporting persons that no other reports were required for such persons, Amkor believes that all Section 16(a) filing requirements applicable to our officers, directors and ten-percent stockholders were complied with in a timely fashion. 89

(2) Potential realizable value is based on the assumption that: (1) our common stock will appreciate at the compound annual rate shown from the date of grant until the expiration of the option term and (2) that the option is exercised at the exercise price and sold on the last day of its term at the appreciated price. We assume stock appreciation of 5% and 10% pursuant to rules promulgated by the Securities and Exchange Commission, and these percentages do not reflect our estimate of future stock price growth. (3) These options were granted pursuant to a voluntary stock option replacement program initiated on November 8, 2002. This program allowed employees and members of our board of directors to surrender their existing options and to receive new option grants six months and one day after the tendered options were cancelled. On June 16, 2003, we issued these new option grants equal to the same number of shares surrendered by the employees and members of our board of directors. The exercise price is $10.79 per share, equal to the fair market value of common stock as of the new grant date. The vesting term of these new options are similar to the tendered options except the new options contain an additional one-year vesting period prior to any options becoming exercisable. 91

YEAR-END OPTION VALUES The following table shows the number of shares covered by both exercisable and non-exercisable stock options held by our Chief Executive Officer and our four other most highly compensated employees as of December 31, 2003, which include all three of our executive officers as of December 31, 2003 other than our Chief Executive Officer. Also reported are the values for "in-the-money" options which represent the positive spread between the exercise price of any such existing stock options and the year-end price of our common stock.

OPTION REPRICING On November 8, 2002, we initiated a voluntary stock option replacement program. This program allowed employees and members of our board of directors to surrender existing options and to receive new option grants six months and one day after the tendered options were cancelled. On June 16, 2003, we issued new option grants equal to the same number of shares surrendered. The exercise price is $10.79 per share, equal to the fair market value of common stock as of the new grant date. The vesting term of these new options are similar to the tendered options except the new options contain an additional one-year vesting period prior to any options becoming exercisable. The following table shows the number of shares re-granted on June 16, 2003 to our Chief Executive Officer and our four other most highly compensated employees, which include all three of our executive officers as of December 31, 2003 other than our Chief Executive Officer: LENGTH OF ORIGINAL NUMBER OF SECURITIES EXERCISE PRICE OPTION UNDERLYING MARKET PRICE OF STOCK AT TIME OF NEW EXERCISE TERM REMAINING AT NAME DATE OPTIONS REPRICED AT TIME OF REPRICING REPRICING PRICE DATE OF REPRICING ---- ------- -------------------- --------------------- -------------- ------------ ----------------- James J.

The Compensation Committee believes that such equity incentives are a significant factor in our ability to attract, retain and motivate officers, employees, and directors who are critical to our business plan and long-term success. As a result of the decline in the fair market value our common stock in the several months prior to November 8, 2002, many of our officers, employees and directors held stock options with exercise prices substantially in excess of the fair market value our common stock. It was the view of the Compensation Committee that stock options with exercise prices substantially above the fair market value of our common stock were viewed negatively by, and provided little incentive to, the holders of these options. After considering various alternatives to address employee retention, compensation incentives and long-term compensation issues, the Compensation Committee approved the option exchange program described above. In approving this exchange program, the Compensation Committee was of the opinion that the disparity between the original exercise prices of the outstanding stock options and the fair market value of our common stock did not provide a meaningful incentive or retention device to the service providers holding such stock options. The Compensation Committee therefore decided that offering the option exchange program was in the best interests of Amkor and its stockholders. 93

Under the exchange program, employees and members of our board of directors could elect to surrender their existing options and be granted new options no earlier than six months and one day after the tendered options were cancelled. Pursuant to the terms and conditions of the offer to exchange, a total of 1,633 eligible employees participated. On June 16, 2003, we granted 6,978,563 shares of our common stock under the 1998 Stock Plan and 35,000 shares of our common stock under the 1998 Director Option Plan for the options tendered by eligible employees and members of our board of directors and accepted by Amkor. For options that were granted under the previously existing 1998 French Plan, which was terminated in April 2003, and that were surrendered pursuant to voluntary stock option replacement program, we granted an additional 248,200 replacement options under the 1998 Stock Plan. We have issued new option grants equal to the same number of shares surrendered by the employees. The exercise price of the new options was $10.79, which was equal to the fair market value of our stock price on the date of grant. The vesting term of these new options are similar to the tendered options except the new options contain an additional one-year vesting period prior to any options becoming exercisable. MEMBERS OF THE COMPENSATION COMMITTEE Winston J. Churchill Thomas D. George DIRECTOR COMPENSATION We do not compensate directors who are also employees or officers of our company for their services as directors. Non-employee directors, however, are eligible to receive: (1) an annual retainer of $25,000 as of January 2003, (2) $2,000 per meeting of the board of directors that they attend, (3) $2,000 per meeting of a committee of the board of directors that they attend and (4) $500 per non-regularly scheduled telephonic meeting of the board of directors in which they participate. We also reimburse non-employee directors for travel and related expenses incurred by them in attending board and committee meetings. 1998 Director Option Plan: Our board of directors adopted the 1998 Director Option Plan (the "Director Plan") in January 1998. A total of 300,000 shares of common stock have been reserved for issuance under the Director Plan. The option grants under the Director Plan are automatic and non-discretionary. As of January 1, 2003, the Director Plan provides for an initial grant of options to purchase 20,000 shares of common stock to each new non-employee director of the company when such individual first becomes an outside director. In addition, each non-employee director will automatically be granted subsequent options to purchase 10,000 shares of common stock on each date on which such director is re-elected by the stockholders of the company, provided that as of such date such director has served on the board of directors for at least six months. The exercise price of the options is 100% of the fair market value of the common stock on the grant date. The term of each option is ten years and each option granted to a non-employee director vests over a three year period. The Director Plan will terminate in January 2008 unless sooner terminated by the board of directors. If all or substantially all of our assets are sold to another entity or we merge with or into another corporation or entity, the acquiring entity or corporation may either assume all outstanding options under the Director Plan or may substitute equivalent options. Following an assumption or substitution, if the director is terminated other than upon a voluntary resignation, any assumed or substituted options will vest and become exercisable in full. If the acquiring entity does not either assume all of the outstanding options under the Director Plan or substitute an equivalent option, each option issued under the Director Plan will immediately vest and become exercisable in full. The Director Plan will terminate in January 2008 unless sooner terminated by the board of directors. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Compensation Committee currently consists of Messrs. Churchill and George. No member of the Compensation Committee was an officer or employee of Amkor or any of Amkor's subsidiaries during fiscal 2003. None of Amkor's Compensation Committee members or executive officers has served on the board of directors or on the compensation committee of any other entity one of whose executive officers served on our board of directors or on our Compensation Committee. 94

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS The following table sets forth certain information regarding the beneficial ownership of our outstanding common stock as of January 31, 2004 by: - - each person or entity who is known by us to beneficially own 5% or more of our outstanding common stock; - - each of our directors; and - - each Named Executive Officer as of fiscal year end.

(a) The number and percentage of shares beneficially owned is determined in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended. The information is not necessarily indicative of beneficial ownership for any other purpose. Under this rule, beneficial ownership includes any share over which the individual or entity has voting power or investment power. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of our common stock subject to options held by that person that will be exercisable on or before March 31, 2004 are deemed outstanding. Unless otherwise indicated, each person or entity has sole voting and investment power with respect to shares shown as beneficially owned. (b) Represents 29,727,093 shares held by James J. and Agnes C. Kim; 139,516 shares issuable upon the conversion of convertible debt held by Mrs. Kim that is convertible on or before March 31, 2004; 14,457,344 shares held by the David D. Kim Trust of December 31, 1987, 14,457,344 shares held by the John T. Kim Trust of December 31, 1987; 6,257,344 shares held by the Susan Y. Kim Trust of December 31, 1987; and 8,200,000 shares held by the Trust of Susan Y. Kim dated April 16, 1998 established for the benefit of Susan Y. Kim's minor children, with Susan Y. Kim as the Trustee. James J. and Agnes C. Kim are husband and wife and, accordingly, each may be deemed to beneficially own shares of our common stock held in the name of the other. David D. Kim, John T. Kim and Susan Y. Kim are children of James J. and Agnes C. Kim. Each of the David D. Kim Trust of December 31, 1987, John T. Kim Trust of December 31, 1987 and Susan Y. Kim Trust of December 31, 1987 has in common Susan Y. Kim and John F.A. Earley as co-trustees, in addition to a third trustee (John T. Kim in the case of the Susan Y. Kim Trust and the John T. Kim Trust, and David D. Kim in the case of the David D. Kim Trust) (the trustees of each trust may be deemed to be the beneficial owners of the shares held by such trust). All of the above-referenced trusts, together with their respective trustees and James J. and Agnes C. Kim may be 95

considered a "group" under Section 13(d) of the Exchange Act on the basis that the trust agreement for each of these trusts encourages the trustees of the trusts to vote the shares of our common stock held by them, in their discretion, in concert with James Kim's extended family. This group may be deemed to have beneficial ownership of 73,238,641 shares or approximately 41.8% of the outstanding shares of our common stock. Each of the foregoing persons stated that the filing of their beneficial ownership reporting statements shall not be construed as an admission that such person is, for the purposes of Section 13(d) or 13(g) of the Exchange Act, the beneficial owner of the shares of our common stock reported as beneficially owned by the other such persons. (c) Includes 20,000 shares issuable upon the exercise of stock options that are exercisable by Mr. Churchill on or before March 31, 2004. (d) Includes 30,001 shares issuable upon the exercise of stock options that are exercisable by Mr. George on or before March 31, 2004. (e) Includes 30,001 shares issuable upon the exercise of stock options that are exercisable by Mr. Hinckley on or before March 31, 2004. (f) Dr. Knorr has no stock options which are exercisable on or before March 31, 2004. (g) Includes 25,001 shares issuable upon the exercise of stock options that are exercisable by Mr. Neff on or before March 31, 2004.

EQUITY COMPENSATION PLANS The following table summarizes our equity compensation plans as of December 31, 2003: (c) (a) NUMBER OF SECURITIES NUMBER OF REMAINING AVAILABLE SECURITIES TO BE (b) FOR FUTURE ISSUANCE ISSUED UPON WEIGHTED-AVERAGE UNDER EQUITY EXERCISE OF EXERCISE PRICE OF COMPENSATION PLAN OUTSTANDING OUTSTANDING (EXCLUDING SECURITIES OPTIONS OPTIONS REFLECTED IN COLUMN (a)) ---------------- ----------------- ----------------------- Equity compensation plans approved by stockholders........ 15,618,070 $11.84 78,675 (1)-(3) Equity compensation plans not approved by stockholders.... 171,500 $17.12 128,500 (4) (1) Includes 18,502 options which were reserved for issuance under the 1998 Stock Plan and 60,000 options which were reserved for issuance under the 1998 Director Option Plan. The 1998 Stock Option Plan for French Employees terminated in April 2003 and, accordingly, no options were reserved for issuance at December 31, 2003. On November 8, 2002, we initiated a voluntary stock option replacement program such that employees and members of our board of directors could elect to surrender their existing options and be granted new options no earlier than six months and one day after the tendered options were cancelled. Pursuant to the terms and conditions of the offer to exchange, a total of 1,633 eligible employees participated. On June 16, 2003, we granted 6,978,563 shares of our common stock under the 1998 Plan and 35,000 shares of our common stock under the Director's Plan for the options tendered by eligible employees and members of our board of directors and accepted by our company. For options that were previously granted under the 1998 French Plan and were surrendered pursuant to this program, we granted an additional 248,200 replacement options under the 1998 Plan. We have issued new option grants equal to the same number of shares surrendered by the employees. The exercise price of the new options was $10.79, which was 96

equal to the fair market value of our stock price on the date of grant. The vesting term of these new options are similar to the tendered options except the new options contain an additional one-year vesting period prior to any options becoming exercisable. (2) As of December 31, 2003, 173 shares of common stock were available for sale under the 1998 Employee Stock Purchase Plan; and there is a provision for an annual replenishment to bring the number of shares of common stock available for sale under such plan up to 1,000,000 as of each January 1. On January 1, 2004, 999,827 additional shares were made available pursuant to the annual replenishment provision. (3) As of December 31, 2003, a total of 18,502 shares were reserved for issuance under the 1998 Stock Plan, and there is a provision for an annual replenishment to bring the number of shares of common stock reserved for issuance under the plan up to 5,000,000 as of each January 1. On January 1, 2004, 4,981,498 additional shares were made available pursuant to the annual replenishment provision. (4) On September 9, 2003, we adopted the 2003 Nonstatutory Inducement Grant Stock Plan (the "2003 Plan"). The 2003 Plan generally provides for the grant to employees, directors and consultants of stock options and stock purchase rights. The 2003 Plan terminates at the discretion of the Board of Directors. As of December 31, 2003, a total of 128,500 shares were available for issuance under the 2003 Plan, and there is a provision for an annual replenishment to bring the number of shares of common stock reserved for issuance under the plan to 300,000 as of each January 1. On January 1, 2004, 171,500 additional shares were made available pursuant to the annual replenishment provision. ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS We have had a long-standing relationship with Anam Semiconductor, Inc. ("ASI"). ASI was founded in 1956 by Mr. H. S. Kim, the father of Mr. James Kim, our Chairman and Chief Executive Officer. Through our supply agreements with ASI, we historically had a first right to substantially all of the packaging and test services capacity of ASI and the exclusive right to all of the wafer output of ASI's wafer fabrication facility. With our acquisition of K1, K2 and K3 in May 2000, we no longer received packaging and test services from ASI. Under the wafer fabrication services supply agreement which was consummated in January 1998 and terminated as of February 28, 2003, we had the exclusive right but not the requirement to purchase all of the wafer output of ASI's wafer fabrication facility on pricing terms negotiated annually. As part of our strategy to sell our investment in ASI and to divest our wafer fabrication services business, we entered into a series of transactions beginning in the second half of 2002: - - In September 2002, we sold 20 million shares of ASI common stock to Dongbu Group in exchange for 5700 Korean won per share, the market value of ASI common stock as traded on the Korean Stock Exchange at the time we entered into the share sale agreement. We received $58.1 million in net cash proceeds and 42 billion won (approximately $34.2 million based on the spot exchange rate on the closing date) of interest bearing notes from Dongbu Corporation payable in two equal principal payments in September 2003 and February 2004. The Dongbu Group comprises Dongbu Corporation, Dongbu Fire Insurance Co., Ltd. and Dongbu Life Insurance Co., Ltd., all of which are Korean corporations and are collectively referred to herein as "Dongbu." Associated with this transaction, we recorded a $1.8 million loss. Additionally, we divested one million shares of ASI common stock in connection with the payment of certain advisory fees related to this transaction. On September 30, 2003, we received 21 billion won (approximately $18.3 million based on the September 30, 2003 spot exchange rate), consisting of the principal amount due under the notes from Dongbu. The remaining principal, or 21 billon won (approximately $17.8 million based on the spot exchange rate on the transaction date), was received on February 10, 2004. - - In separate transactions designed to facilitate a future merger between ASI and Dongbu, (i) we acquired a 10% interest in Acqutek from ASI for $1.9 million, the market value of the shares as publicly traded in Korea; (ii) we acquired the Precision Machine Division ("PMD") of Anam Instruments, a related party to Amkor, for $8 million, its fair value; and (iii) Anam Instruments, which had been partially owned by ASI, utilized the proceeds from the sale of PMD to us to buy back all of the Anam Instruments shares owned by ASI. Acqutek supplies materials to the semiconductor industry and is publicly traded in Korea. An entity controlled by the family of James Kim, our Chairman and Chief Executive Officer, held a 25% ownership interest in Acqutek at the time of our acquisition of our interest in Acqutek. We have historically purchased and continue to purchase leadframes from Acqutek. On September 17, 2003, we sold our entire ownership interest in Acqutek. PMD supplies sophisticated die mold systems and tooling to the semiconductor industry and historically over 90% of its sales were to Amkor. We determined the fair value of PMD based on projected cash flows 97

discounted at a rate commensurate with the risk involved. At the time of our acquisition of PMD, Anam Instruments was owned 20% by ASI and 20% by a family member of James Kim. - - On February 28, 2003, we sold our wafer fabrication services business to ASI for $62 million. We negotiated the fair value of our wafer fabrication services business with ASI and Dongbu. The parties calculated fair value based on an assessment of projected cash flows discounted at a rate commensurate with the risk involved. We obtained a release from Texas Instruments regarding our contractual obligations with respect to wafer fabrication services to be performed subsequent to the transfer of the business to ASI. Each of the transactions with Dongbu, ASI and Anam Instruments are interrelated and it is possible that if each of the transactions were viewed on a stand-alone basis without regard to the other transactions, we could have had different conclusions as to fair value. It is likely that we would not have entered into the Acqutek or PMD transactions absent the share sale to Dongbu and the sale of the wafer fabrication services business to ASI. Had these transactions not been interrelated, we may have utilized a different negotiation strategy for the investment in Acqutek and the acquisition of PMD, which could have resulted in us reaching a different conclusion of the fair value of both of these transactions. Pursuant to the definitive agreements, (1) Amkor and Dongbu agreed to use reasonable best efforts to cause Dongbu Electronics and ASI to be merged together as soon as practicable, (2) Amkor and Dongbu agreed to cause ASI to use the proceeds ASI received from its sale of stock to Dongbu to purchase shares in Dongbu Electronics and (3) Amkor and Dongbu agreed to use their best efforts to provide releases and indemnifications to the chairman, directors and officers of ASI, either past or incumbent, from any and all liabilities arising out of the performance of their duties at ASI between January 1, 1995 and December 31, 2001. The last provision would provide a release and indemnification for James Kim, our CEO and Chairman, and members of his family. We are not aware of any claims or other liabilities which these individuals would be released from or for which they would receive indemnification. At January 1, 2001 and 2002 Amkor owned 42% of ASI's voting stock. During 2002, we divested 21 million shares of ASI stock and at December 31, 2002 Amkor owned 26.7 million shares of ASI or 21%. The carrying value of our investment in ASI at December 31, 2002 was $77.5 million, or $2.90 per share. Beginning March 24, 2003, we ceased accounting for our investment in ASI under the equity method of accounting and commenced accounting for our investment as a marketable security that is available for sale. As of December 31, 2003, we owned 14.7 million shares of ASI, or 12% of ASI's voting stock. The carrying value of our remaining investment in ASI at December 31, 2003, including an unrealized gain of $10.0, was $50.4 million, or $3.43 per share. We intend to sell our remaining investment in ASI. The ultimate level of proceeds from the sale of our remaining investment in ASI could be less than the current carrying value. We have had other relationships with ASI affiliated companies for construction services and equipment. We believe each of these transactions was conducted on an arms-length basis in the ordinary course of business. Total purchases from ASI and its affiliates for the years ended December 31, 2003, 2002 and 2001 were $31.1 million, $212.6 million and $161.6 million. Construction services and equipment purchases received from ASI and its affiliates capitalized during the years ended December 31, 2002 and 2001 were $2.8 million and $14.7 million, respectively. We received less than $0.1 million of construction services from ASI and its affiliates during 2003. Total purchases from Acqutek included in cost of revenue for 2003, 2002 and 2001 were $16.1 million, $16.0 million and $14.0 million, respectively, which we believe were conducted on an arms-length basis in the ordinary course of business. We entered into indemnification agreements with our officers and directors. These agreements contain provisions which may require us, among other things, to indemnify the officers and directors against certain liabilities that may arise by reason of their status or service as directors or officers (other than liabilities arising from willful misconduct of a culpable nature). We also agreed to advance them any expenses for proceedings against them that we agreed to indemnify them from. As of December 31, 2003, Mr. James Kim and members of his immediate family beneficially owned approximately 42% of our outstanding common stock. Amkor Electronics, Inc. (AEI), which was merged into our company just prior to the initial public offering of our company in May 1998, elected to be taxed as an S Corporation under the provisions of the Internal Revenue Code of 1986 and comparable state tax provisions. As a result, AEI did not recognize U.S. federal corporate income taxes. Instead, the stockholders of AEI were taxed on their proportionate share of AEI's taxable income. Accordingly, no provision for U.S. 98

federal income taxes was recorded for AEI. Just prior to the initial public offering, AEI terminated its S Corporation status at which point the profits of AEI became subject to federal and state income taxes at the corporate level. We consummated a tax indemnification agreement between us, our predecessor and James Kim and his family (collectively, the "Kim Family"). James Kim, is our founder and significant stockholder, and currently serves as our Chairman and CEO. Under the terms of the tax indemnification agreement, Amkor indemnifies the former owners of AEI for the settlement of AEI's S Corporation federal and state tax returns and any adjustments to the reported taxable income. At the time AEI was converted to a C Corporation, AEI and the Kim Family identified certain federal and state tax overpayments associated with the results of AEI during S Corporation status years and AEI, in May 1998, paid such amounts to the Kim Family. These amounts, which principally related to the finalization of AEI's federal tax return, were reflected as a receivable from stockholders in the stockholders' equity section of our balance sheets. As the refunds were paid by the associated taxing authorities and received by the Kim Family, the Kim Family, in turn, remitted the funds to Amkor. During 2002, $0.4 million of tax refunds were received by the Kim Family and used to pay down the stockholder receivables. During the fourth quarter of 2003, the receivable was collected in full. At December 31, 2002, other noncurrent assets included $6.0 million for the cash surrender value of life insurance policies in which the beneficiary was our Chairman and CEO. In December 2003, our Chairman and CEO paid to us $6.0 million for this asset, the book value and fair value of the asset at that time, and accordingly, no balance exists at December 31, 2003. We lease office space in West Chester, Pennsylvania from certain of our stockholders. The lease expires in 2006. We have the option to extend the lease for an additional 10 years through 2016. Amounts paid for this lease in 2003 were $1.1 million. Our sublease income includes $0.5 million in each of the three years ended December 31, 2003 from a company in which certain related parties have ownership interests. In January 1998, we loaned $120,000 to Mr. Boruch, our President and Chief Operating Officer, which was repaid in full in 2003. ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES PricewaterhouseCoopers LLP has served as our independent accountants since 2000. The following table shows the fees paid or accrued by us for the fiscal years 2003 and 2002. Certain 2002 amounts have been reclassified to conform to the current year presentation: YEAR ENDED DECEMBER 31, ----------------------- 2003 2002 ---------- ---------- (IN THOUSANDS) Audit fees........................................................................ $ 1,549 $ 1,453 Audit-related fees (a)............................................................ 56 53 Tax fees (b)...................................................................... 58 52 All other fees.................................................................... -- -- ---------- --------- Total.......................................................................... $ 1,663 $ 1,558 ========== ========= (a) Audit-related fees consist primarily of fees associated with employee benefit plan audits, accounting consultations; as well as due diligence related activity performed during 2002. (b) Tax fees consist primarily of fees associated with tax compliance services. Our Audit Committee is required to pre-approve the audit and non-audit services performed by our principal accountants, PricewaterhouseCoopers LLP, in accordance with the Amkor Audit and Non-Audit Services Pre-Approval Policy. This policy provides for pre-approval of audit, audit-related, tax services and other services specifically described by the Audit Committee. The policy also provides for the general approval of additional individual engagements, which, if they exceed certain pre-established thresholds, must be separately approved by the Audit Committee. This policy authorizes the Audit Committee to delegate to one or more of its members pre-approval authority with respect to permitted services, provided that any such pre-approval decisions must be reported to the Audit Committee. 100% of the above principal accountant services were approved by the Audit Committee during 2003, which concluded that the provision of such services by PricewaterhouseCoopers LLP was compatible with the maintenance of that firm's independence in the conduct of its auditing functions. 99

Exhibit 14.1 Code Of Business Conduct And Ethical Guidelines November 2003

Dear Amkor Colleagues, As representatives of Amkor Technology, Inc. and our subsidiaries ("Amkor"), we are each responsible for helping to define our company in a positive way. The purpose of this Code of Business Conduct and Ethical Guidelines is to assist us in understanding the values and beliefs that we share, and stand for as an organization. It offers many guidelines, but it cannot make decisions for you. You should seek guidance from your supervisor, human resources or the legal department if you have questions. We urge each employee to thoroughly read this booklet and discuss it with his or her supervisor. Through our alignment to our values, and in demonstrating commitment to this code of conduct, we will ensure that our message to our constituencies and each other is clear. The Amkor team will operate at the highest level of integrity and strive to demonstrate exemplary behavior. Sincerely, Jim Kim John Boruch Chairman and Chief Executive Officer President and Chief Operating Officer

I. DEFINITION AND APPLICABILITY To run our business effectively, we developed management tools that include a mission statement, corporate values and strategic objectives. In addition, we created this Code of Business Conduct and Ethical Guidelines upon which we base the operation of our business. This Code of Business Conduct and Ethical Guidelines is a standing guide for handling business situations in an honest and professional manner, and should be used in determining key business decisions and actions. We designed this code to deter wrongdoing and to promote: - - Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships; - - Full, fair, accurate, timely, and understandable disclosure in reports and documents that we file with, or submit to, the Securities and Exchange Commission and in other public communications made by us; - - Compliance with applicable governmental laws, rules and regulations; - - The prompt internal reporting to an appropriate person or persons identified in the code of violations of the code; and - - Accountability for adherence to the code. This code applies to all Amkor employees worldwide. These principles are not intended to be all-inclusive, but they do provide important information about the company's established way of doing business. Local or department guidelines may be issued in various offices to supplement or implement the principles. International laws or customs may sometimes require us to modify the practices that we have outlined here. If you have any questions or concerns about the proper course of action, discuss the situation with your supervisor or with human resources. Any amendment or waiver of this Code of Business Conduct and Ethical Guidelines for our executive officers or senior financial officers, including the Chief Financial Officer and Controller, must be approved in writing by the board of directors and promptly disclosed as required by law or stock exchange regulations. Please keep in mind that failure to conduct business in compliance with these guidelines may result in disciplinary action, up to and including termination. These guidelines should be a part of your daily working practices. If you need further guidance in applying them to your specific situation, your supervisor or manager should be able to help you. In some cases, you may need to contact a group such as the legal department or human resources for more specific guidelines or opinions. When in doubt, ask! Your understanding of these guidelines will help to ensure that the company and our employees conduct their business with uncompromising integrity and professionalism. 3

II. OUR VALUES Our business environment is constantly changing. We can count on changes in our products, our people, our customers, and our suppliers. What will not change is our commitment to our company values. Our values are the foundation for sustaining our business environment within Amkor. They are: - - Respect and Integrity - - High Energy - - Teamwork and Cooperation - - Caring and Well Being of our People - - Open Communication These values define who we are as a company -- to each other, to our customers, our suppliers and to our shareholders. They define what we stand for, and they are guiding principles for behavior. Our company values are demonstrated through the following examples: RESPECT & INTEGRITY - - When we need to give constructive feedback to each other, we speak about the issue, not the person. We are not condescending or rude. - - Respect goes beyond how we treat each other and includes how we treat the company. - We conserve and optimize our resources -- this includes time and money. - We speak highly of Amkor. - - We do not give our word unless we know we can meet our commitment. - - We recognize that gossip is destructive, and we strive to eliminate it. HIGH ENERGY - - When a customer presents us with a challenge, our first response is to look for ways to meet their needs. We respond eagerly to opportunities for innovative thinking. - - We know that enthusiasm is spirited by people who support each other, so we make a concentrated effort to offer support when others are down, and to back each other up when the pressure is on. - - We boldly take calculated risks. TEAMWORK & COOPERATION - - Knowing we cannot get our job done without other people, we have team/departmental meetings to keep our people up to date on new information. - - We use a team approach in decision making by involving key players before a commitment is made. - We recognize people who contribute to our success. 4

CARING & WELL BEING OF OUR PEOPLE - - We support one another in finding the best ways to maximize their contributions to Amkor's success -- through personal growth, learning and development, or job changes. - - We make a point to have fun in our work because it refuels and inspires us. - - We encourage each other to think and act creatively and go beyond the fears that inhibit growth. OPEN COMMUNICATION - - We are accessible to one another. - - We deal openly and honestly with conflict by taking concerns directly to the person responsible. Our focus is on the issue, not the person. - - We recognize the importance of sharing our ideas, expressing gratitude and recognizing others. Our values provide the foundation of our business culture, and our Code of Business Conduct and Ethical Guidelines provides information about the way business is conducted at Amkor. These guidelines provide the foundation for understanding how to handle most business situations in the honest and professional manner expected of every Amkor employee. 5

III. ETHICS AND COMPLIANCE HONEST AND ETHICAL CONDUCT We expect all employees to act with the highest standards of honesty and ethical conduct while working on our company's premises, at offsite locations where Amkor business is being conducted, at Amkor sponsored business and social events, or at any other place where the employees are representing Amkor. In all cases, if you are unsure about the appropriateness of an event or action, please seek assistance in interpreting the requirements of these practices by contacting your supervisor or Amkor's legal department. COMPLIANCE WITH APPLICABLE RULES AND REGULATIONS All Amkor employees must comply with all applicable laws and regulations. Employees are expected to be familiar with the legal and regulatory requirements applicable to their business responsibilities and to fulfill their duties in accordance with these laws and regulations. Questions concerning the applicability of any legal or regulatory provision should be directed to Amkor's legal department. FOREIGN CORRUPT PRACTICES ACT Among other things, the Foreign Corrupt Practices Act prohibits bribing any public official, government, or other individual-regardless of nationality or local custom to secure any concession, contract, or favorable treatment. Bribes include any kickbacks or other unlawful payments. BRIBES, KICKBACKS, GIFTS AND GRATUITIES BRIBES AND KICKBACKS Amkor employees may not offer or accept a bribe or a kickback. A bribe is defined as a thing of value given to someone with the intent of obtaining favorable treatment from the recipient. Kickbacks consist of payment in cash or in kind, including goods, services, the use of another company's property, or forgiving any sort of obligation provided to a customer or supplier for the purpose of improperly obtaining or rewarding favorable treatment in connection with a sale or purchase. Bribes and kickbacks may not be offered either directly or through a third party in order to obligate the recipient to return the favor. 6

Sample Situation: - - Paying a freight forwarder to expedite a shipment through customs is not acceptable if the agent doesn't follow applicable rules and regulations, and if the agent gives money or payment in kind to a government official for personal benefit. On the other hand, expediting by following rules and regulations and without bribing officials is acceptable. - - Questions about specific cases should be sent to the legal department. RECEIVING GIFTS AND GRATUITIES Any form of a gift that obligates an employee is a bribe and is forbidden, regardless of its value. Cash gifts are not allowed, whether for referring an Amkor employee to a recruiter, for purchasing favors or for sales to outside parties. A sample from a customer or supplier is Amkor property and is not for personal use or profit. No entertainment shall be accepted in any circumstance from present or potential suppliers, unless it is a multi-customer event, sanctioned in a professional environment and does not, or appear to, influence purchasing decisions, create a conflict of interest or violate rules or proprietary exchanges of information. No favors, services, travel or lodging of any kind from present or potential suppliers may be accepted. Working meals are acceptable if the work performed is proximate to a supplier or third party facility and passes the common sense test for reasonable behavior in a business environment. Promotional items with company logos are acceptable as long as their value is less than $100. If an item's value is unclear, the item should be returned. If it cannot be returned, it must be turned over to the company. The gift can then be given to a charitable organization. If employees know that they will receive a gift of value, they can suggest that instead of a gift, a donation be made in their honor to a charity. Some Sample Situations: - - Business discussions held at lunch or dinner are legitimate. A free private meal for an employee and spouse is not a legitimate function. - - An invitation to an entertainment or sporting event such as a golf or tennis tournament may be appropriate if it demonstrably helps build a business relationship. When unsure about proper conduct, an employee should describe the situation to his or her manager and the legal department. Policy violations should be reported promptly to the legal department. GIVING GIFTS AND GRATUITIES Equivalent rules apply to the giving of gifts. Obviously, they should not be offered as bribes. Care should be taken to avoid giving gifts that are intended to be innocent but may be construed as a bribe especially with respect to gifts to government officials for which strict 7

rules apply. An acceptable gift to a business person might be perceived as a bribe to a government worker. When in doubt, contact the legal department. - - It is permissible to give away plaques, supplier awards and prizes that are part of official programs with fair, openly-published rules for competing companies. - - Samples may not be provided to a customer for private use. Free access to company resources or assets, such as computer time, and scrap or excess materials, is expressly forbidden. - - In some countries other than the U.S., local customs require the exchange of gifts under certain circumstances. In these cases, the country manager may ask for an exception through a written request to the legal department. Such requests must specify the manager's understanding of the country's customs and the proposed rules for gift giving and receiving, including the occasions on which such gifts may be exchanged and the dollar equivalent value of such gifts to be permitted. If approved, the country manager may publish such rules to affected employees on an exception basis. Gifts outside the provisions of the approved local rules cannot be given or received without approval from the legal department. 8

IV. CONFLICT OF INTEREST AND USING INSIDER INFORMATION CONFLICT OF INTEREST It is Amkor's policy that all employees avoid any activity that is or has the appearance of being hostile, adverse or competitive with the company, or that interferes with the proper performance of duties, responsibilities or loyalty to the company. An employee's best course of action is to review the specific situation with his or her supervisor to assess whether there are any problems and, if so, how they can be resolved. If the employee's supervisor concludes that there is or may be a perceived conflict of interest, the manager will consult with the legal department. The legal department will work with the vice president of purchasing, the regional sales manager or appropriate employee management to determine if there is a real or perceived conflict of interest. If a conflict exists, it may be necessary to transfer that employee, require the employee to divest himself or herself of the interest, or remedy the situation as a condition of continued employment. Some Sample Situations: - - If an employee is in a position to influence the business situation of a supplier or customer, the employee must disclose to his or her supervisor all financial, proprietary or other type of controlling or influencing interest (for example, a member of the immediate family or a close personal friend) that the employee may directly have. (Note: Financial or proprietary interest includes investments, ownership of securities or loan agreements.) - - Any employee in a position to influence the purchase of materials or services must formally declare any situation wherein a member of the employee's immediate family or a close personal friend is employed by Amkor's supplier. A conflict of interest form is normally used to make this declaration. - - It is not Amkor's policy to discourage the employment of family members or employees' close personal friends as suppliers or competitors. Clearly, everyone is entitled to pursue a career of his or her choice. It is the company's intention, however, to ensure that neither real nor apparent influence is exerted in its business relationships as a result of such employment. - - Amkor will not conduct business with a former employee who becomes employed by a supplier or who offers his or her services as an independent contractor for a period of 12 months from the employee's termination date, without prior written approval from the vice president of purchasing. - - An employee may not directly or indirectly conduct outside business that interferes with the proper performance of the employee's job at Amkor, is conducted during an employee's normal working hours, or utilizes Amkor confidential information or specialized skills and knowledge gained as an employee of the company. This includes becoming a contractor, consultant or supplier to Amkor while being employed at Amkor. - - Employees may not enter into any short sales or short positions with respect to Amkor securities. Certain employees who are in particularly sensitive positions are required to complete a conflict of interest form each year. The internal audit department will provide these forms. The completed 9

and signed forms must be returned to the internal audit department. Employees completing conflict of interest forms must properly notify the internal audit department of any changes to their responses. USING INSIDER INFORMATION Employees may at some time have access to information related to our company or our business that is not known to the general public. This is known as "insider information." It is Amkor policy that insider information may not be used at any time for improper purposes. PROTECTING INSIDER INFORMATION Insider information may not be disclosed to anyone outside the company, except for the purpose of conducting company business. STOCK TRANSACTIONS AND MATERIAL INSIDER INFORMATION Some insider information may be considered material; that is, it is information that could affect Amkor's stock price. If an employee has material insider information about the company, than he or she should not trade in company stock until the information is released to the public. Some examples of information that may be material are financial results, plans to acquire another company or planned key product announcements. Certain material insider information that is related to company business may not affect the stock price, but may affect the stock price of another company or the value of other investment opportunities. An Amkor employee may not use this material insider information to gain personal financial benefit. This type of insider information would include, for example, Amkor's plan to make a major investment in another company or to award a large piece of business to a supplier. In all situations, if an employee is prohibited by this policy from acting for his or her own benefit (for example, by trading stock or investing), than he or she may not "tip" another person to act. Securities laws prohibit trading stock based on material insider information. A violation of these laws can result in civil and criminal penalties. Any issue regarding this type of transaction should be reviewed with the legal department. 10

V. EMPLOYMENT PRACTICES EMPLOYEES AND THE WORKPLACE ENVIRONMENT NONDISCRIMINATION AND DIVERSITY Amkor respects, values and welcomes diversity in our workforce, as well as in our customers, our suppliers and the global marketplace. Amkor's policy is to comply with all applicable laws and to provide equal employment opportunity for all applicants and employees without regard to non-job related factors such as race, color, religion, sex, national origin, ancestry, age, disability, veteran status, marital status or sexual orientation. This policy applies to all areas of employment, including recruitment, hiring, training, promotion, compensation, benefits, transfer, and social and recreational programs. AT-WILL EMPLOYMENT Unless otherwise agreed in writing and subject to any applicable law, each Amkor employee is employed by Amkor on an at-will-basis. This means that employment is not guaranteed for any specific duration of time and Amkor retains the right to terminate an individual's employment at any time with or without cause. No oral representations made by any Amkor employee with respect to continued employment can alter this relationship. HARASSMENT-FREE WORKPLACE Amkor is committed to providing a workplace free of all types of harassment. Amkor strongly disapproves of, and will not tolerate, harassment of employees by managers or co-workers. Amkor will also provide a work environment to protect employees from harassment by non-employees in the workplace. Harassment includes verbal, physical and visual conduct that creates an intimidating, offensive or hostile working environment or that interferes with work performance. Some examples include racial slurs; ethnic or sexual jokes; offensive statements, posters or cartoons; intimidation tactics; distribution of inappropriate jokes or offensive language on electronic mail or any other Amkor computer or networks; use of pornographic screens or software; or other similar conduct. Sexual harassment includes behaviors such as solicitation of sexual favors, unwelcome sexual advances or other verbal, visual or physical conduct of a sexual nature. OPEN COMMUNICATION Amkor promotes performance, teamwork and results through open communications. We encourage communications meetings at all sites where employees have the opportunity to share any concerns with senior management. Amkor also supports an "open door" management policy. Employees are encouraged to raise work-related concerns with their immediate manager. If this is not the most appropriate person, they are encouraged to bring their concerns to the attention of the functional manager, human resources or any senior manager, up to and including the corporate vice 11

president. Employees can also send their questions to the Amkor Connect newsletter regarding clarification of company values, policies and standard practices. These questions may be sent anonymously, if desired. PERFORMANCE MANAGEMENT Performance management is an ongoing process of setting clear expectations, holding employees accountable for meeting those expectations, and directly and effectively addressing performance issues. Managing employee performance is a responsibility that is shared by managers and employees. Amkor formally appraises the performance of employees worldwide every year. The evaluation provides the employee with a documented review of performance and may result in a change in compensation. Employee performance is measured against factors such as individual performance expectations, departmental and/or corporate business objectives, contributions to team efforts, performance relative to peers and performance to company values. Input on performance may be gathered from several sources, including managers, peers, subordinates and customers. Performance is documented each March using the Performance Appraisal Form, available on ATDOCs. This form was designed very simply, to allow managers and employees to discuss performance results as well as areas for improvement. Remaining competitive requires that Amkor employees strive for continuous improvement in performance. Amkor encourages employees to take responsibility for their career development by maintaining and developing useful and marketable skills. In addition, managers are encouraged to provide a supportive environment to assist employees in career development. WORKPLACE VIOLENCE Amkor has a policy of zero tolerance for violence. Violence includes physically harming another, shoving, pushing, harassing, intimidating, coercing, brandishing weapons, and threatening or talking of engaging in those activities. It is Amkor's intent to ensure that everyone associated with the business, including employees and customers, never feels threatened by any employee's actions or conduct. It is everyone's business to prevent violence in the workplace. Employees can help by reporting any workplace incident that could indicate a co-worker is in trouble. Employees are encouraged to report any incident that may involve a violation of any of the company's policies that are designed to provide a comfortable workplace environment. Concerns may be presented to your supervisor, human resources, or the legal department. All reports will be investigated and information will be kept confidential. COMPENSATION AND BENEFITS Amkor's compensation and benefits philosophy, which distinguishes the company and contributes to our success, is an integral part of our culture and management approach. 12

TOTAL COMPENSATION AND PHILOSOPHY The total compensation approach responds to the cyclical nature of our business. This philosophy is based on creating a pay structure that we can maintain in down cycles while being among the best paying in good times. This is accomplished through a combination of base pay, benefits and variable, profit-driven components such as cash and stock. EQUITY Pay equity is a method that Amkor uses to ensure that market pay rates are obtained in dynamic growth areas. These pay adjustments typically respond to specific job functions. COMPETITIVE COMPENSATION AND BENEFITS PACKAGES To strike a balance between Amkor's need to be viable and profitable, and the needs and desires of our employees, each country's compensation package is designed to be competitive with those of a select group of comparable companies within that country. The individual program components of a specific country may differ from local practices in that country to be consistent with Amkor's culture. WORK HOURS At Amkor, being at work on time and being available during normal business hours are part of our company's commitment to our customers and co-workers. Start times are generally consistent with local business start times for the geography in which Amkor operates. Amkor does not support flexible work hours (a program in which employees can arrive at work anytime between set hours). ALTERNATE START TIMES Alternate start times (starting at other than the local business start time on a regular basis) are supported only when business requirements can be met or exceeded as a result of the change. Setting an alternate work schedule or start time for an employee or group of employees may be approved by a manager in the following circumstances: - - To accommodate a specific shift structure in facilities, manufacturing or other departments that use varied shifts as a part of the business. - - To accommodate regular business communication needs with a team or customers in geographies or time zones other than one's own. - - To accommodate an employee who has a disability or family hardship, as long as there is no undue hardship on the business results. - - To support local commuter traffic restrictions or requests from the city or country, as long as business requirements are not jeopardized. Employees with alternate start times must have their supervisor's approval. 13

ENVIRONMENTAL, SAFETY AND HEALTH Amkor is committed to achieving a safe, healthy and environmentally friendly workplace, and is dedicated to principles and practices of "continuous improvement" in striving to provide high quality Environmental, Safety and Health (ESH) standards and practices for team members, customers, visitors, suppliers and the communities in which we live and work. Amkor shall continue to demonstrate environmental responsibility through compliance with all relevant environmental regulations; implementation and monitoring guidelines; and training of team members to minimize the opportunity for environmental insult to include proper storage, transportation and disposal of hazardous waste materials, conservation of natural resources and energy management. Amkor shall strive to eliminate accidents, occupational injuries and workplace illnesses by providing the appropriate training and support for team members, suppliers, contractors and visitors. Amkor shall ensure that safety and environmental responsibility take precedence over expediency, and that our ESH standards meet international and local requirements. Amkor expects all team members to comply with the ESH policy by getting the appropriate education and training to carry out ESH requirements in all phases of work and business. Amkor shall communicate and make available our ESH policy, objectives and programs to all team members, suppliers, contractors and the public to encourage and promote the positive participation in achieving our goals for environmental responsibility, safety and health. Amkor shall establish and maintain appropriate controls, including periodic reviews, to ensure adherence to this policy. PHYSICAL SECURITY Amkor aims to provide a secure business environment for the protection of our employees, products, valuable materials, equipment and proprietary systems and information. Materials, equipment and systems incorporated into the design of facilities and grounds will ensure adequate security in these areas. Security is the responsibility of all employees. Any breach of security should be reported immediately to your supervisor. IDENTIFICATION AND BADGING Anyone entering an Amkor facility is required to wear an Amkor-issued identification badge. Badges should be visible at all times. All badges are the property of Amkor and must be returned upon request. No modifications or additions should be made that interfere with the visibility, clarity or use of the badge. 14

AMKOR COMPANY ASSETS AND COMPANY RIGHT TO SEARCH Amkor does not allow the unauthorized removal of company assets or physical property from our premises, or sharing of our intellectual property in an unauthorized manner. To ensure proper protection of our employees and assets, Amkor regulates the possession and movement of assets, subject to the limitations imposed by local law. Areas subject to search include an employee's workspace, desk, computer, file cabinet, locker or similar place where employees may place personal possessions, whether or not such places are locked. Such inspections or searches may also include, but are not limited to, computer files, floppy disks, hard drives, e-mail or other electronic mail; an employee's vehicle when on Amkor property; or items of personal property while on Amkor property. INTERNAL INFORMATION POSTING Amkor has a number of methods for posting information located within the facilities and on information systems for the purpose of communicating. Posting in any of these places is limited to company-related material, including statutory and legal notices, safety and disciplinary rules, company policies, memos, announcements of general interest and other items relating to Amkor. All postings require prior approval by the office manager at each site who manages the posting place in question. QUALITY Amkor is committed to pursue quality in every aspect of our business. Therefore, we strive to: - - Continuously improve our company -- people, processes, product quality and cost of ownership, technology, service and delivery -- and achieve/maintain world-class competitiveness in each of these areas. - - Build in customer-defined quality at each step as our products are developed, manufactured, delivered and supported. BUSINESS RESULTS Successful quality practices will: - - Foster adherence to Amkor corporate values and promotes a culture where excellence is expected, commitments are honored, and teamwork, openness, hard work, and dedication to process improvement and quality results are a daily routine for everyone. - - Encourage the continuous improvement of our products, processes, and people to become better, faster and more cost effective in everything we do. - - Require us, individually and collectively, to understand the needs of our internal/external customers and satisfy them in a way that ensures mutually beneficial business results. - - Promote the quest for quality and competitiveness at Amkor, in the semiconductor business, global industry and the communities where we live. 15

DEPLOYMENT All managers will: - - Provide quality leadership and direction for all management functions and quality related activities at Amkor. - - Ensure each employee understands the Code of Business Conduct and Ethical Guidelines. - - Provide the appropriate environment for each employee to implement the Quality principle. All employees will: - - Talk, act and make decisions consistent with the tenets of this principle. - - Promote teamwork and support the improvement efforts of others for the good of Amkor as a whole. EMPLOYEE REIMBURSEMENT/ADVANCES Amkor's intention is to fund management-approved business travel, education, relocation, in/expatriate expenses, business entertainment and other expenses necessary to conduct our business. The employee is responsible for the accuracy, completeness and timely filing of the required forms, including appropriate backup documentation for receiving reimbursements, advances of funds or credit card purchases. It is the responsibility of the approving manager to ensure that reimbursable expenses or funds advanced are reasonable, ordinary and necessary to conduct Amkor's business. In addition, human resources is responsible for collecting funds and credit cards from terminating employees. 16

VI. BUSINESS PRACTICES ANTITRUST COMPLIANCE The purpose of antitrust laws in the United States and other countries where Amkor does business is to encourage competition, which benefits consumers by prohibiting unreasonable restraints on trade. It is company policy to compete vigorously while at the same time adhering to both the letter and spirit of antitrust laws. Some of the more common antitrust problem areas are discussed next. RESTRAINTS OF TRADE Any agreement, understanding or arrangement expressed or implied, formal or informal, in restraint of trade or commerce is prohibited by antitrust laws. All employees must avoid even the appearance of engaging in the restraint of trade. All questions should be referred to the legal department. DEALING WITH COMPETITORS It is against Amkor policy to have a discussion or communication with any competitor relating to price or any matter that affects pricing, including costs, credit terms, allocation of markets, geographies, customers or lines of business. FINANCIAL REPORTING AND EXTERNAL COMMUNICATIONS FULL, FAIR, ACCURATE, TIMELY AND UNDERSTANDABLE DISCLOSURE IN OUR COMPANY'S FILINGS AND PUBLIC COMMUNICATIONS The Chief Executive Officer and the senior financial officers have the direct and primary responsibility to ensure full, fair, accurate, timely and understandable disclosure in Amkor's filings and public communications. Senior financial officers include the Chief Financial Officer, the Controller and each of their direct reports who have responsibility for the preparation of financial statements and public disclosure of financial information, and persons performing similar functions at our subsidiaries. The information included in all filings with the SEC and the Nasdaq Stock Market, and all other public communication must be complete, timely and accurate, and must not omit any material fact required so that the information disclosed is not misleading. Since accurate records play a vital role in assuring the maintenance of high ethical standards, all employees have responsibility to record all transactions accurately, completely and in a timely manner. Never make false or artificial entries in any company records. Never understate or overstate reports of sales or expenses, or alter any documents used to support those reports. Our financial statements must fairly and accurately present the financial condition of the business. Reporting Amkor's proper financial condition is a fundamental aspect of each employee's responsibilities. Reporting false information is strictly prohibited. 17

Amkor maintains a system of internal controls to assure appropriate authorization, recording and accountability of our company's assets. Amkor's internal control system is never to be intentionally circumvented. All of our company's books and records are subject to review and audit. When employees are asked to respond to requests by internal auditors, legal staff and independent accountants, responses must be complete and truthful. Employees must include all relevant information, even if the request is not specific as to what information is required. If you know something that could be relevant, it must be disclosed. All records shall be prepared accurately, reliably, honestly and in accordance with established finance and accounting procedures. An employee must not enter false or misleading information into records and must report to management any transaction they feel is questionable. INTERACTION WITH INDEPENDENT ACCOUNTANTS It is prohibited to take any action to fraudulently influence, coerce, manipulate or mislead an independent accountant who is engaged in the performance of an audit or review of Amkor's financial statements for the purpose of rendering the financial statements misleading. Types of conduct that would constitute improper influence, include, but are not limited to, directly or indirectly: - - Offering or paying bribes or other financial incentives, including offering future employment or contracts for non-audit services; - - Providing an auditor inaccurate or misleading legal analysis; - - Threatening to cancel or canceling existing audit or non-audit engagements if the independent accountant objects to the company's accounting; - - Seeking to have a partner removed from the audit engagement because the partner objects to the company's accounting; - - Blackmailing; - - Making physical threats. RECORDS RETENTION Business documents and records are important company assets. They contain data and information critical to the continuity of our business, preserve information necessary to protect our legal rights and support and document tax and other regulatory requirements. Employees are prohibited from tampering with company records or removing or destroying them prior to the dates specified in record retention schedules. PUBLIC RELATIONS/PRESS It is Amkor's intention to maintain open and consistent communications with the media. To ensure the accuracy of all information provided, spokespeople are designated to respond to all inquiries. Except for designated spokespeople, individual employees should not respond on Amkor's behalf to policy inquiries in any public forum, including the Internet, on-line services and 18

the press a even when they are visiting our facilities. All press inquiries should be forwarded immediately to the director of Marketing Communications, to the local Public Relations manager or to a designated spokesperson. EMPLOYEE POSTING ON THE INTERNET Amkor employees may choose, or be required by their jobs, to participate in public forums on the network, Internet mailing lists and so on. Employees may not represent Amkor's corporate opinion in these forums unless they have been specifically asked to do so. To avoid confusion, employees should indicate in their postings that the views they express are their own and not those of Amkor. If the posting is not obviously from an Amkor site, employees should clearly identify their affiliation with Amkor. Employees should remember that, even with this disclaimer, they will be identified with Amkor and that their network behavior reflects on the company in a broader way. In addition, employees should never comment on confidential or internal company matters, and should never comment on pending legal actions involving Amkor, our customers or our partners. All comments should be well informed and within the employee's sphere of expertise. Further, if the posting affects others at Amkor those affected should be copied on the posting or be advised of it in advance. 19

VII. USE AND PROTECTION OF ASSETS AND ELECTRONIC SYSTEMS USE AND PROTECTION OF ASSETS PROTECTION OF COMPANY ASSETS Every Amkor employee is responsible for protecting the assets of the company. Each employee is also responsible for understanding Amkor's obligations for protecting assets that have been entrusted to it by customers or suppliers, and for treating them accordingly. The company's assets include physical assets, such as equipment and buildings, as well as our funds, intellectual property, trade secrets and confidential information. To protect Amkor's assets, they must be adequately safeguarded. This means locking up and securing valuable assets. Amkor's assets may not be sold, borrowed, lent, given away or modified in any way that would impact their value, unless there is a good business reason and with approval of the department manager. USE OF COMPANY RESOURCES Company resources, including (but not limited to) cash, personnel, equipment and vehicles may only be used for legitimate company business purposes. Some sample situations: - - An Amkor employee may not make business trips or purchase an airline ticket at a premium price just to obtain frequent flier miles or other awards for his or her private use. - - No one outside the company may have access to our computers. - - In some cases, using an Amkor PC to do personal work is permissible if it is clearly outside of business hours and you have your manager's approval. Be sure that you and your supervisor agree on the exact meaning of "outside of business hours." INFORMATION SECURITY Confidential information generated by or used in any company business activity is considered an information asset. This includes (but is not limited to) information originating from direct access to computer systems, information carried over networks, information preserved on portable electronic media and information appearing in hard-copy format. At the time of hire, all employees must sign an agreement to protect Amkor's confidential information and intellectual property rights during and after employment with Amkor. Upon termination of employment, employees must provide Amkor with any company owned material or proprietary information (i.e., patents, designs, data), and authorize ownership of that information to Amkor. 20

Amkor requires that each employee be personally responsible for safeguarding the company's information assets, in all its various forms, from loss, inappropriate modification and disclosure to anyone who lacks either the authorization or the need-to-know. All employees are required to: - - Protect the confidentiality of information such as product roadmaps, strategic long-range plans, product pricing, and employee salary data, which, if disclosed, could cause financial or other damage to Amkor. - - Hold in confidence and not use (except for the benefit of Amkor) any confidential information that they have access to or that was created by them while employed at Amkor. - - Protect third-party confidential information in the manner required by the terms of a Memorandum of Agreement. If such terms are not known, that information should not be used, copied or disclosed until the terms of the Memorandum of Agreement are known. - - Ensure that confidential information that may need to be released to customers or suppliers is handled properly. In such cases, an employee must have received proper authorization (approval from their manager or the legal department) and must ensure that the recipient has a need-to-know and signs a nondisclosure agreement. Requests for confidential information from outside sources must be handled only by authorized persons. - - Be personally accountable to Amkor and legally accountable for their actions. EMERGENCY MANAGEMENT PLAN Amkor aims to provide our customers with flawless delivery of the products and services they need and want. Amkor recognizes that a wide variety of natural, human-caused, and physical and information system failures can happen. Plans must be in place and responsible people trained at all sites to ensure that employees, guests and neighbors are protected from injury; that Amkor's assets are protected from damage or loss; and that the effects of such an incident do not severely compromise Amkor's ability to achieve our mission. Although these incidents cannot always be avoided, reducing the duration of an unplanned outage may control their severity. This may be accomplished by repetitively exercising recovery plans to ensure that they work when needed, and by taking preventative actions and measures to reduce the risk or impact when an occurrence is likely (such as in war zones). Every major site and function must have an Emergency Management Plan reviewed by management and tested periodically. Preparations must include a cost-effective combination of emergency response, recovery planning, protection of critical data via backup, and secure storage and interim processes until normal services can be resumed. During emergency situations, Amkor's communications with the press must be timely, honest and accurate, and they should not compromise the company's reputation. Except for designated spokespersons, individual employees should not respond to public inquiries from the press or any other forum during a time of emergency. 21

VIII. VIOLATIONS OF THE CODE AND THE ETHICS HOTLINE REPORTING VIOLATIONS OF THE CODE If an employee needs assistance in evaluating proposed conduct, or if an employee observes or suspects any violation of the Code of Business Conduct and Ethical Guidelines, he or she should first tell his or her supervisor. If the employee is uncomfortable speaking with his or her supervisor for any reason, he or she should contact, human resources, the legal department, or internal audit or call the confidential Ethics Hotline at 877-22AMKOR (877-222-6567). The confidential Ethics Hotline is operated by an independent third party provider. Callers can remain anonymous when calling the Ethics Hotline and the representative with whom the caller speaks will respect that decision. The Ethics Hotline is available 24-hours a day, 7 days a week from any location in the world. Nearly all languages can be accommodated when calling the Ethics Hotline, including Korean, Tagalog, Japanese and Mandarin. To obtain the toll-free Amkor telephone number from outside the U.S., a caller will first dial the AT&T Direct Access Code for the country he or she in, then dial 877-22AMKOR (877-222-6567). Specific country dialing instructions can be found on the Amkor's intranet site, by asking the local Amkor human resources department, or by calling the local AT&T telephone operator. Every report received will be investigated promptly, and a caller may make a report without giving his or her name. RETALIATION Employees can raise their concerns of violations of the Code of Business Conduct and Ethical Guidelines, or other illegal or unethical conduct without fear that they will be disciplined or terminated. We will not permit retaliation of any kind against an employee for reporting information in good faith, which means telling the truth as the employee knows it to be, to his or her supervisor, an Amkor manager, a human resource representative or the Ethics Hotline. VIOLATIONS OF THE CODE Amkor will take appropriate disciplinary actions, up to and including termination, for any violation of this Code of Business Conduct and Ethical Guidelines. 22

EXHIBIT 14.2 AMKOR TECHNOLOGY, INC. DIRECTOR CODE OF ETHICS 1. DUTIES AND RESPONSIBILITIES. This Code of Ethics ("Code of Ethics" or "Code") is a guide to your ethical and legal responsibilities with respect to your status as a director of Amkor Technology, Inc. ("Amkor"). It is the primary duty of the Board of Directors (the "Board") of Amkor to oversee the CEO and other senior management in the competent and ethical operation of the corporation. To satisfy this duty, the directors will attend regularly scheduled Board meetings and interface with company management as appropriate, with a focus toward ensuring that the corporation is committed to business success through maintenance of the highest standards of responsibility and ethics. Directors bring to Amkor a wide range of experience, knowledge and judgment, and bring these skills to bear for Amkor. These varied skills mean that good governance depends on far more than a "check the box" approach to standards or procedures. The governance structure in Amkor is designed to be a working structure for principled actions, effective decision-making and appropriate monitoring of both compliance and performance. Effective directors maintain an attitude of constructive skepticism and careful review. Our directors know that their job requires them to ask probing questions of management and to take the action necessary to understand material decisions on the part of management, which they are asked to review. Our directors also rely on the advice, reports and opinions of management, counsel and our expert advisers. Finally, the Board is committed to staying current on best governance practices. We intend to monitor the way we govern ourselves, including reviewing whether there are alternatives or new ideas which would strengthen our governance structures. 2. GENERAL CONFLICTS OF INTEREST. Each board member must ensure that other existing and anticipated future commitments do not materially interfere with the member's service as a director. 3. PERSONAL BENEFIT FROM AMKOR BUSINESS. You may not receive any material personal profit or advantage in connection with any transaction involving Amkor without requisite disclosure and approval. You must disclose to our General Counsel all situations where, to your knowledge, an Amkor entity is conducting business that results or will result in a material personal profit or advantage to you.

4. INVESTMENTS IN OTHER BUSINESSES. You may not have a material personal or family financial interest in any Amkor supplier, customer, reseller or competitor that might cause divided loyalty, or the appearance of divided loyalty without requisite disclosure and approval. Whether there may be divided loyalty depends on many factors, including your ability to influence Amkor decisions that affect your personal interest, the size of the investment relative to your other resources, and the nature of the relationship between our company and the other business. 5. OTHER DIRECTORSHIPS AND POSITIONS. Prior to joining any other board or accepting an executive position with a company that does business with Amkor or competes with Amkor, you must consult with Amkor's Chairman of the Governance Committee. If in your position as a director, officer or employee of another organization you encounter any situation where your role with that other organization is in conflict with Amkor's interests, you must inform Amkor's Chairman of the Governance Committee of the conflict. 6. CONFIDENTIALITY IN GENERAL. Amkor business and technical information that you learn as a result of your position at Amkor is company property and must be kept confidential. 7. HANDLING NEWS ABOUT AMKOR. Confidential information about Amkor, including information that can reasonably be expected to have an impact on the market for Amkor stock, including forward-looking information such as projections of orders, new revenue or earnings, may be released only in accordance with Amkor's guidelines and applicable securities laws. When reasonably possible, contacts with news organizations should be handled through Amkor's department responsible for corporate communications. Individual board members may occasionally meet or otherwise communicate with various constituencies that are involved with Amkor, but it is expected that, when reasonably possible, board members would do this with the knowledge of management and, in most instances, absent unusual circumstances or as contemplated by the committee charters, at the request of management. Amkor's policy is to provide full, fair, accurate, timely, and understandable disclosure in reports and documents that Amkor files with, or submits to, the SEC and in Amkor's other public communications. Accordingly, board members must ensure that they and others in the company comply with Amkor's disclosure controls and procedures and Amkor's internal controls for financial reporting. In the event any individual board member believes or suspects that any information that is filed with, or submitted to the SEC, or otherwise made publicly available is materially inaccurate or misleading, or if such board member has identified or has suspicion of a material weakness in Amkor's public reporting procedures, such board member shall promptly raise such concern with the Chairman of the Audit Committee (or other member of the Audit Committee, as may be appropriate). 8. PROFITING FROM INSIDE INFORMATION. As a director, you have information about Amkor that is both material and non-public. You must adhere to Amkor's trading windows and applicable securities laws, and report any trades in Amkor stock. If you violate insider trading laws, both you and Amkor may be subject to severe criminal penalties. Insider trading laws apply to all Amkor directors and apply even to relatively small transactions. -2-

9. HANDLING COMPANY ASSETS. Every director must take care to safeguard Amkor assets. This includes protecting them from unauthorized use. Use of Amkor assets for any unlawful or improper purposes is strictly prohibited. 10. RELATIONSHIP TO OTHER POLICIES. If you are an Amkor employee, the Amkor Code of Business Conduct and Ethical Guidelines also apply to you. If you are a member of a committee of the Board of Directors, the applicable committee charter(s) should also guide your conduct. 11. WAIVERS AND AMENDMENTS OF THE CODE. Amkor is committed to continuously reviewing and updating our policies and procedures. Therefore, this Code is subject to modification. Any amendment or waiver of any provision of this Code must be approved in writing by the Board of Directors and promptly disclosed, along with the reasons for any waiver, pursuant to applicable laws and regulations. 12. VIOLATIONS; INVESTIGATIONS. All Amkor directors are required to review this Code in order to answer questions and ensure compliance. Violations of this Code should be reported to the Chairman of the Audit Committee; provided that if the alleged violation involves the Chairman of the Audit Committee, then the violation should be reported to the remaining members of the Audit Committee; provided further, that if the alleged violation involves the Chairman of the Audit Committee and at least one other member of the Audit Committee, then the violation should be reported to the remaining members of the Board of Directors. The process to report violation shall be through the Company's Ethics Hotline at 877.22 Amkor. Callers can remain anonymous when calling the Ethics Hotline. Please refer to the Company's website at www.aanet.amkor.com for further information regarding the Ethics Hotline. Amkor shall promptly investigate any reported or suspected violations of the Code. Amkor shall determine whether a violation of this Code has occurred after providing the alleged violator with an opportunity to respond to the allegations. Amkor will strive to enforce the Code in a consistent and fair manner while accounting for all relevant information. Amkor will take appropriate action against any person whose actions are found to violate this Code or any other policy of Amkor. Reprisal, threats, retribution or retaliation against any person who has in good faith reported a violation or a suspected violation of law, this Code or other Amkor policies, or against any person who is assisting in any investigation or process with respect to such a violation, is prohibited. Notwithstanding the foregoing, if Amkor's audit committee establishes procedures regarding complaints or concerns related to accounting, internal accounting controls, or auditing that are inconsistent with the foregoing, such procedures established by the audit committee shall apply. -3-
