                                  THE COMPANY
 
     Amkor is the world's largest independent provider of semiconductor
packaging and test services. The Company believes that it is also one of the
leading developers of advanced semiconductor packaging and test technology in
the industry. The Company offers a complete and integrated set of packaging and
test services including integrated circuit ("IC") package design, leadframe and
substrate design, IC package assembly, final testing, burn-in, reliability
testing, and thermal and electrical characterization. As of December 31, 1997,
the Company had in excess of 150 customers, including many of the largest
semiconductor companies in the world. Such customers include, among others,
Advanced Micro Devices, Inc., International Business Machines Corp., Intel
Corporation, Lucent Technologies, Inc., Motorola, Inc., National Semiconductor
Corp., Philips Electronics N.V., SGS-THOMSON Microelectronics N.V., Siemens AG
and Texas Instruments, Inc. ("TI").
 
     Today, nearly all of the world's major semiconductor companies outsource
some or all of their packaging and test needs. The increasing complexities,
investment requirements and time to market pressures associated with IC design
and production, combined with the growth in the number of ICs being produced and
sold, are driving increasing demand for independent packaging and test services.
According to industry estimates, independent packaging foundry revenues are
expected to grow at a compound annual rate of 16% over a period of five years
from $5.6 billion in 1996 to $11.6 billion in 2002.
 
   
     The Company provides packaging and test services through its three
factories in the Philippines as well as four factories of Anam Semiconductor,
Inc. (formerly Anam Industrial Co., Ltd.) ("AICL") in Korea pursuant to a supply
agreement between the Company and AICL. The Company and AICL have had a long-
standing relationship. In 1996, 1997 and the three months ended March 31, 1998,
approximately 72%, 68% and 67%, respectively, of the Company's revenues were
derived from sales of services performed for the Company by AICL. In addition,
substantially all of the revenues of AICL in 1996 and 1997 were derived from
services sold by the Company. Mr. James Kim, the Company's Chairman and Chief
Executive Officer, is a director of AICL, and he and other members of his family
beneficially own approximately 40.7% of AICL's outstanding common stock. The
Company expects that the businesses of the Company and AICL will continue to
remain highly interdependent by virtue of their supply relationship, overlaps
and family ties between their respective shareholders and management, financial
relationships, coordination of product and operation plans, joint research and
development activities and shared intellectual property rights.
    
 
     The Company recently began offering wafer fabrication services through
AICL's new deep submicron CMOS foundry capable of producing 15,000 8" wafers per
month. Through a strategic relationship with TI, the Company and AICL have
qualified .25 micron CMOS process technology, and TI has agreed to provide to
AICL .18 micron CMOS process technology during 1998. AICL's foundry will
primarily manufacture DSPs, ASICs and other logic devices. By leveraging the
Company's leading position in semiconductor packaging and
                                        3
<PAGE>   5
 
test services, the new wafer fabrication services have enabled the Company to
become one of the first providers of a fully integrated, turnkey semiconductor
fabrication, packaging and test service solution.
 
     The Company's strategy is to: (i) maintain its product technology
leadership by continuing to design and produce leading-edge packaging
technology; (ii) maintain advanced manufacturing capabilities through continuous
advancement and refinement of its process technology; (iii) leverage the scale
and scope of its packaging and test capabilities to provide Amkor with several
competitive advantages, including procurement of key materials and manufacturing
equipment, the ability to capitalize on economies of scale and the ability to
offer an industry-leading breadth of product offerings; (iv) establish industry
packaging standards to bolster sales of leading-edge, high margin and high
growth product lines; (v) enhance customer and supplier relationships; (vi)
continue to focus on customer support; and (vii) provide an integrated, turnkey
solution comprised of wafer fabrication, packaging and test services.
 
     The Company was organized under the laws of Delaware in September 1997 to
consolidate the ownership of several affiliated entities in the same business
and under common management. See "Reorganization." The Company's principal
executive offices are located at 1345 Enterprise Drive, West Chester, PA 19380
and its telephone number at that address is (610) 431-9600.
 
                          THE INITIAL PUBLIC OFFERING
 
   
     On April 30, 1998, the Company commenced the initial public offering of
35,000,000 shares of Common Stock (5,000,000 of which were offered by James Kim,
a stockholder of the Company (the "Selling Stockholder")) at a price to the
public of $11.00 per share and $180,000,000 aggregate principal amount of
Convertible Notes (the "Initial Public Offering"). In connection with the
Initial Public Offering, the Company granted the underwriters of the Initial
Public Offering (the "Underwriters") 30-day options to purchase up to 5,250,000
additional shares of Common Stock and $27,000,000 additional principal amount of
Convertible Notes solely to cover over-allotments, if any. These options were
exercised in full by the Underwriters. As a result, the Company sold an
aggregate of 35,250,000 shares of Common Stock and $207,000,000 of Convertible
Notes in the Initial Public Offering. Salomon Smith Barney was a representative
of the Underwriters.
    
 
   
     The net proceeds to the Company from the Initial Public Offering were
approximately $559,757,500, after deducting the underwriting discounts and
estimated offering expenses. The Company did not receive any proceeds from the
sale of the shares of Common Stock offered by the Selling Stockholders.
    
 
   
     Approximately $154 million of the net proceeds to the Company from the
Initial Public Offering were used to repay the Non-Compliant Loans (as defined
herein), which, following planned repayments of portions thereof prior to the
Initial Public Offering, had outstanding balances of $43 million, $50 million
and $61 million. These loans were due May 1998, October 2000 and April 2001,
respectively, and accrued interest annually at rates equal to 7.16%, 6.78% and
6.68%, respectively, at December 31, 1997, which rates represent LIBOR plus a
spread. The $43 million loan was incurred in August 1997 in order to redeem $40
million of Floating Rate Notes issued by Amkor/Anam Pilipinas, Inc., a
subsidiary of the Company ("AAP"), and to repay certain short-term debt. The
Company was not in compliance with certain covenants under the above-described
loans. These loan covenants included restrictions on the ability of one of the
Company's subsidiaries to enter into transactions with affiliates, requirements
that the subsidiary maintain certain debt-to-equity ratios and requirements that
the subsidiary comply with certain notice requirements. As a result of such non-
compliance, these loans had been classified as current liabilities in the
Company's financial statements included herein, and the report of the Company's
independent public accountants with respect to such financial statements
previously contained a paragraph stating that there was substantial doubt as to
the ability of the Company to continue as a going concern. Repayment of such
loans from the proceeds of the Initial Public Offering eliminated these events
of non-compliance. Consequently, these loans have been reclassified as
non-current liabilities and this paragraph has been deleted from the report of
the Company's independent public accountants.
    
 
                                        4
<PAGE>   6
 
   
     Approximately $65 million of the net proceeds to the Company from the
Initial Public Offering shall be used to repay numerous short-term bank loans
incurred primarily to finance capital expenditures for the Company's P1 factory
in the Philippines and for working capital. All of these loans were due within
12 months of December 31, 1997 and bore interest at rates ranging from 8.0% to
12.2%. In addition, approximately $8 million of the net proceeds will be used to
repay two term loans of approximately $3 million and $5 million. These loans are
due September 1999 and January 2001, respectively, and accrue interest annually
at rates equal to 9.09% and 11.88%, respectively, at December 31, 1997, which
rates represent LIBOR plus a spread.
    
 
   
     An additional approximately $34 million of the net proceeds to the Company
will be used to purchase AICL's 40% interest in AAP. Approximately $86 million
of the net proceeds were used to repay all of the amounts due to Anam USA, Inc.,
a wholly-owned subsidiary of AICL ("AUSA"). The remaining $213 million of such
net proceeds will be used for capital expenditures and working capital. Pending
such uses, the net proceeds to the Company of the Initial Public Offering have
been invested in investment grade, interest-bearing securities.
    
 
                                USE OF PROCEEDS
 
     This Prospectus relates to the offer and sale of shares of Common Stock
whereby Salomon Smith Barney may, subject to certain limitations, from time to
time borrow from Mr. James Kim and his wife, Mrs. Agnes Kim ("Mr. and Mrs.
Kim"), to settle short sales of Common Stock (or to return Common Stock
previously borrowed by Salomon Smith Barney to settle such short sales) entered
into by Salomon Smith Barney to hedge any long position in the Convertible Notes
resulting from its market-making activities. See "Plan of Distribution." The
Company will not receive any proceeds from the sale of the Common Stock to which
this Prospectus relates.

(1) Net income for 1997 reflects a $17.3 million loss related primarily to the
    impairment of value of the Company's equity interest in AICL. This
    investment was sold in 1998. See "Management's Discussion and Analysis of
    Financial Condition and Results of Operations" and Note 6 of Notes to
    Combined Financial Statements.
 
(2) Prior to the reorganization of the Company, Amkor Electronics, Inc. ("AEI"),
    a predecessor of the Company, elected to be taxed as an S Corporation under
    the Internal Revenue Code of 1986 and comparable state tax laws.
    Accordingly, AEI did not recognize any provision for federal income tax
    expense during the periods presented herein. The pro forma adjustment for
    income taxes reflects the additional U.S. federal income taxes which would
    have been recorded by the Company if AEI had not been an S Corporation
    during these periods. See "Reorganization" and Note 1 of Notes to Combined
    Financial Statements.
 
(3) EBITDA is defined as earnings before interest, taxes on income, depreciation
    and amortization. EBITDA is presented here to provide additional information
    about the Company's ability to meet its future debt service, capital
    expenditure, and working capital requirements and should not be construed as
    a substitute for or a better indicator of results of operations or liquidity
    than net income or cash flow from operating activities computed in
    accordance with generally accepted accounting principles.
 
   
(4) For purposes of calculating the ratio of earnings to fixed charges, earnings
    consist of income before income taxes less undistributed earnings in less
    than 50%-owned subsidiaries, plus fixed charges. Fixed charges consist of
    interest expense incurred and one-third of rental expense which amount is
    deemed by the Company to be representative of the interest factor of rental
    payments under operating leases. The supplemental pro forma ratio of
    earnings to fixed charges reflects the effect on the ratio of earnings to
    fixed charges as if the Initial Public Offering had been completed and the
    net proceeds to the Company applied as described in "-- The Initial Public
    Offering" at the beginning of the period presented.
    
 
   
(5) Pro forma balance sheet data reflects (i) the termination of AEI's S
    Corporation status which resulted in the recording of a deferred tax asset
    of $1.5 million and (ii) a distribution by the Company of undistributed
    earnings of AEI through March 31, 1998 of $35.7 million to stockholders of
    AEI prior to the reorganization of the Company. The amount actually
    distributed by the Company to such stockholders of AEI will reflect the
    amount of undistributed net income (loss) recognized by AEI and Amkor
    Technology, Inc. following March 31, 1998 and prior to such reorganization.
    See "Reorganization -- Termination of S Corporation Status and
    Distributions" and Notes 1, 16 and 17 of Notes to Combined Financial
    Statements.

(6) As adjusted to give effect to the application of the net proceeds to the
    Company of the Initial Public Offering, including the purchase from AICL of
    its 40% interest in AAP for approximately $34 million and the related
    elimination of minority interest and recording of goodwill. The acquisition
    of the minority interest will result in additional amortization of
    approximately $2.5 million per year. Also reflects repayments made after
    March 31, 1998 and prior to the Initial Public Offering of $2.5 million of
    amounts due to AUSA (non-current) and the purchase of AK Industries, Inc.
    for $3 million. See "-- The Initial Public Offering," "Reorganization" and
    Notes 1, 6 and 16 of Notes to Combined Financial Statements.
    
 
   
     Capitalized terms used in this summary have the meanings ascribed to such
terms elsewhere in this Prospectus. Unless the context otherwise requires, all
references in this Prospectus to the "Company" or "Amkor" are to Amkor
Technology, Inc. and its subsidiaries. Prior to the Reorganization (as defined
under "Reorganization"), such subsidiaries were under common management and were
in the same business. As a result, the financial statements presented herein
have been prepared on a combined basis. Unless otherwise indicated, all
information in this Prospectus gives effect to (i) the Reorganization which was
consummated on April 29, 1998, including the issuance of 82,610,000 shares of
Common Stock in connection therewith, and (ii) the Initial Public Offering and
the application of the net proceeds therefrom. See "-- The Initial Public
Offering," "Reorganization," "Description of Capital Stock" and Note 1 of Notes
to Combined Financial Statements. References in this Prospectus to "Korea" are
to the Republic of Korea, and references to "won" or "W" are to the currency of
the Republic of Korea. The won has depreciated significantly against the U.S.
dollar and other foreign currencies in recent months. On May 14, 1998, the base
rate under the market average exchange rate system, as announced by the Korea
Financial Telecommunications and Clearings Institute in Seoul, Korea (the
"Market Average Exchange Rate"), was W1,418 to $1.00. No representation is made
that the won or U.S. dollar amounts referred to herein could have been or could
be converted into U.S. dollars or won, as the case may be, at any particular
rate or at all. Financial information for AICL contained in this Prospectus has
been prepared on the basis of Korean generally accepted accounting principles
("GAAP"), which differ in certain significant respects from U.S. GAAP.
    
 
     Certain technical terms used throughout this Prospectus are defined in the
Glossary appearing immediately prior to the Combined Financial Statements at the

                                  RISK FACTORS
 
     Prospective investors should consider carefully the following risk factors,
in addition to the other information contained in this Prospectus concerning the
Company and its business, before purchasing the shares of Common Stock or the
Convertible Notes offered hereby. Certain statements contained in "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business," including statements
regarding the anticipated growth in the market for the Company's products, the
Company's anticipated capital expenditures and financing needs, the Company's
expected capacity utilization rates, the belief of the Company as to its future
operating performance and other statements contained in this Prospectus that are
not historical facts, are "forward-looking" statements within the meaning of the
U.S. federal securities laws. 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 herein and in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business." These forward-looking
statements are made as of the date of this Prospectus and the Company assumes no
obligation to update such forward-looking statements or to update the reasons
why actual results could differ materially from those anticipated in such
forward-looking statements.
 
FLUCTUATIONS IN OPERATING RESULTS; DECLINES IN AVERAGE SELLING PRICES
 
     The Company's operating results have varied significantly from period to
period. A variety of factors could materially and adversely affect the Company's
revenues, gross profit and operating income, or lead to significant variability
of quarterly or annual operating results. These factors include, among others,
the cyclical nature of both the semiconductor industry and the markets addressed
by end-users of semiconductors, the short-term nature of its customers'
commitments, timing and volume of orders relative to the Company's production
capacity, changes in capacity utilization, evolutions in the life cycles of
customers' products, rescheduling and cancellation of large orders, rapid
erosion of packaging selling prices, availability of manufacturing capacity,
allocation of production capacity between the Company's facilities and those of
AICL, fluctuations in package and test service charges paid to AICL, changes in
costs, availability and delivery times of labor, raw materials and components,
effectiveness in managing production processes, fluctuations in manufacturing
yields, changes in product mix, product obsolescence, timing of expenditures in
anticipation of future orders, availability of financing for expansion, changes
in interest expense, the ability to develop and implement new technologies on a
timely basis, competitive factors, changes in effective tax rates, the loss of
key personnel or the shortage of available skilled workers, international
political or economic events, currency and interest rate fluctuations,
environmental events, and intellectual property transactions and disputes.
Unfavorable changes in any of the above factors may adversely affect the
Company's business, financial condition and results of operations. In addition,
the Company increases its level of operating expenses and investment in
manufacturing capacity based on anticipated future growth in revenues. If the
Company's revenues do not grow as anticipated and the Company is not able to
decrease its expenses, the Company's business, financial condition and operating
results would be materially and adversely affected. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
     Beginning in the third quarter of 1996, intense competition in the
semiconductor industry worldwide resulted in decreases in the average selling
prices of many of the Company's lead frame packages. The Company expects that
average selling prices for its services will continue to decline in the future,
principally due to intense competitive conditions. A decline in average selling
prices of the Company's services, if not offset by reductions in the cost of
producing those services or by a shift to higher margin products, would decrease
the Company's gross margins and could materially and adversely affect the
Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
DEPENDENCE ON THE HIGHLY CYCLICAL SEMICONDUCTOR AND PERSONAL COMPUTER INDUSTRIES
 
     The Company's business is substantially affected by market conditions in
the semiconductor industry, which is highly cyclical and, at various times, has
been subject to significant economic downturns character-
                                        8
<PAGE>   10
 
   
ized by reduced product demand, rapid erosion of average selling prices and
production overcapacity. In addition, the markets for semiconductors are
characterized by rapid technological change, evolving industry standards,
intense competition and fluctuations in end-user demand. Because the Company's
business will be dependent on the requirements of semiconductor companies for
independent packaging, test and wafer fabrication services for the foreseeable
future, any future downturn in the semiconductor industry could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company's operating results for 1996, 1997 and the first three
months of 1998 were adversely affected by a downturn in the semiconductor
market. In addition, a significant portion of the Company's net revenues from
packaging and test services depends on the packaging and testing of
semiconductors used in personal computer ("PC") products. The PC industry is
subject to intense competition, is highly volatile and is subject to significant
shifts in demand. As a result, any deterioration of business conditions in the
PC industry could have a material adverse effect on the Company. See
"Business -- Industry Background" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
    
 
RISKS ASSOCIATED WITH LEVERAGE
 
   
     The Company has historically operated with significant amounts of debt
relative to its equity. At March 31, 1998, the Company had outstanding $406.3
million in principal amount of indebtedness, including non-current amounts due
to Anam USA, Inc. ("AUSA"), a wholly-owned subsidiary of AICL, and the Company
has incurred prior to the Initial Public Offering and intends to continue to
incur additional bank debt in addition to the Convertible Notes issued as part
of the Initial Public Offering. In 1996 and 1997, the Company's payments under
long-term debt agreements (excluding payments to AUSA as described in Note 11 of
Notes to Combined Financial Statements) were $3.1 million and $43.5 million,
respectively. Following the application of the net proceeds to the Company of
the Initial Public Offering and repayments of debt after December 31, 1997 and
prior to the Initial Public Offering, the Company will continue to have at least
$298 million in principal amount of indebtedness outstanding, including $54
million of short-term borrowings and current portions of long-term debt.
    
 
   
     The Company was not in compliance with certain covenants with respect to
certain of its loans, the aggregate outstanding amount of which was $154 million
at March 31, 1998 (the "Non-Compliant Loans"). Such non-compliance in turn
triggered cross-defaults with respect to an additional $10 million of the
Company's loans. These loan covenants included restrictions on the ability of
one of the Company's subsidiaries to enter into transactions with affiliates,
requirements that the subsidiary maintain certain debt-to-equity ratios and
requirements that the subsidiary comply with certain notice requirements. As a
result of such non-compliance, these loans had been classified as current
liabilities in the Company's financial statements included herein, and the
report of the Company's independent public accountants with respect to such
financial statements previously contained a paragraph stating that there was
substantial doubt as to the ability of the Company to continue as a going
concern. The Company has eliminated such non-compliance and cross-defaults by
repaying such loans using part of the net proceeds to the Company from the
Initial Public Offering. Consequently, these loans have been classified as
non-current liabilities and this paragraph has been deleted from the report of
the Company's independent public accountants. See "Prospectus Summary -- The
Initial Public Offering."
    
 
   
     At March 31, 1998, the Company had also guaranteed borrowing facilities
available to companies affiliated with James Kim and other stockholders of the
Company totalling $10.7 million, of which $9.5 million was outstanding at March
31, 1998. At March 31, 1998, the Company had $100.4 million of stockholders'
equity and a working capital deficit of $75.6 million. On a pro forma basis,
after giving effect to the termination of AEI's S Corporation status and the
distribution of undistributed net income of AEI through March 31, 1998, the
Company had $66.2 million of stockholders' equity and a working capital deficit
of $111.3 million. On a pro forma as-adjusted basis, after giving effect to the
Initial Public Offering, the Company had $424.4 million of stockholders equity
and working capital of $162.2 million. See "-- Dependence on International
Operations and Sales; Concentration of Operations in the Philippines and Korea"
and "Reorganization -- Termination of S Corporation Status and Distributions."

<PAGE>   11
 
DEPENDENCE ON RELATIONSHIP WITH AICL; POTENTIAL CONFLICTS OF INTEREST
 
   
     AICL was founded in 1956 by Mr. H. S. Kim, who currently serves as the
honorary Chairman and a Representative Director of AICL. AICL is a member of the
Anam group of companies (the "Anam Group"), consisting principally of companies
in Korea in the electronics industries. The management of AICL and the other
companies in the Anam Group are influenced to a significant degree by the family
of H. S. Kim, which, together with the Company, collectively owned approximately
40.7% of the outstanding common stock of AICL as of December 31, 1997. A
significant portion of the shares owned by the Kim family are leveraged and as a
result of this, or for other reasons, the family's ownership could be
substantially reduced. James Kim, the founder of the Company and currently its
Chairman and Chief Executive Officer, is the eldest son of H. S. Kim. Since
January 1992, in addition to his other responsibilities, James Kim has been
serving as acting Chairman of the Anam Group and a director of AICL. Mr. In-Kil
Hwang, the President and a Representative Director of AICL, is the
brother-in-law of James Kim. In addition, four other members of Mr. Kim's family
are on the 13-member Board of Directors of AICL. After the Initial Public
Offering, James Kim and members of his family beneficially owned approximately
65.8% of the outstanding Common Stock of the Company, and Mr. Kim and other
members of his family will continue to exercise significant control over the
Company. See "-- Benefits of the Initial Public Offering to Existing
Stockholders; Continued Control by Existing Stockholders" and "Principal
Stockholders."
    
 
   
     The businesses of the Company and AICL have been interdependent for many
years. In 1996, 1997 and the three months ended March 31, 1998, approximately
72%, 68% and 67%, respectively, of the Company's revenues were derived from
sales of services performed for the Company by AICL. In addition, substantially
all of the revenues of AICL in 1996, 1997 and the three months ended March 31,
1998 were derived from services sold by the Company. The Company expects the
proportion of its revenues derived from sales of services performed for the
Company by AICL and the proportion of AICL's revenues from services sold by the
Company to increase as the Company begins selling the wafer fabrication output
of AICL's new wafer foundry and with the Company's assumption from AICL in
January 1998 of substantially all of the marketing rights for the Japanese
market. In the event the ability of AICL to supply the Company were disrupted
for any reason, the Company's facilities in the Philippines would be able to
fill only a small portion of the resulting shortfall in capacity. In addition,
there are currently no significant third party suppliers of packaging and test
services from which the Company could fill its orders. As a result, the
Company's business, financial condition and operating results will continue to
be significantly dependent on the ability of AICL to effectively provide
contracted services on a cost-efficient and timely basis. The termination of the
Company's relationship with AICL for any reason, or any material adverse change
in AICL's business resulting from underutilization of its capacity, the level of
its debt and its guarantees of affiliate debt, labor disruptions, fluctuations
in foreign exchange rates, changes in governmental policies, economic or
political conditions in Korea or any other change, could have a material adverse
effect on the Company's business, financial condition and results of operations.
    
 
     The Company has recently entered into new supply agreements with AICL (the
"Supply Agreements"). Under the Supply Agreements, AICL has granted to the
Company a first right to substantially all of the packaging and test services
capacity of AICL and the exclusive right to all of the wafer output of its new
wafer foundry. The Company expects to continue to purchase substantially all of
AICL's packaging and test services, and to purchase all of AICL's wafer output,
under the Supply Agreements. Under the Supply Agreements, pricing arrangements
relating to packaging and test services provided by AICL to the Company are
subject to quarterly review and adjustment, and such arrangements relating to
the wafer output provided by AICL to the Company are subject to annual review
and adjustment, in each case on the basis of factors such as changes in the
semiconductor market, forecasted demand, product mix, capacity utilization and
fluctuations in exchange rates, as well as the mutual long-term strategic
interests of the Company and AICL. There can be no assurance that any new
pricing arrangements resulting from such review and adjustment will be favorable
to the Company. Pursuant to long-standing arrangements between AICL and the
Company's operating subsidiaries, sales from AICL to the Company will continue
to be made through AUSA, a wholly-owned financing subsidiary of AICL. Under the
Supply Agreements, the Company will continue to reimburse AUSA for the financing
costs incurred by it in connection with trade financing provided to the Company.
The Supply Agreements also provide that Amkor-Anam, Inc., a subsidiary of the
Company, will continue to provide raw material procurement and related
 
                                       10
<PAGE>   12
 
services to AICL on a fee basis. The Supply Agreements have a five-year term and
may be terminated by any party thereto upon five years' written notice at any
time after the expiration of such initial five-year term. There can be no
assurance that AICL will not terminate either Supply Agreement upon the
expiration of such initial term or, if it does terminate a Supply Agreement,
that the Company will be able to obtain a new agreement with AICL on terms that
are favorable to the Company or at all.
 
     AICL's ability to continue to provide services to the Company will depend
on AICL's financial condition and performance. AICL currently has a significant
amount of debt relative to its equity, which debt the Company expects will
continue to increase in the foreseeable future. The Company is advised that
AICL, as a public company in Korea, has published its most recent consolidated
financial statements as of and for the year ended December 31, 1997. These
consolidated financial statements are prepared on the basis of Korean GAAP,
which differs significantly from U.S. GAAP. U.S. GAAP financial statements are
not available. The independent auditor's report regarding AICL, included
elsewhere in this Prospectus, includes an explanatory paragraph regarding change
in accounting principles, the impact of the Korean economic situation on AICL
and its ability to continue as a going concern.

     A significant amount of the current and long-term liabilities of AICL are
denominated in U.S. dollars and other foreign currencies. At December 31, 1997,
the amount of U.S. dollar and other foreign currency denominated short-term
borrowings, current maturities of long-term debt, long-term debt (net of current
maturities) and long-term capital lease obligations were W1,222 billion, W59
billion, W159 billion and W834 billion, respectively. Due in part to the
significant depreciation of the won (for example, from a Market Average Exchange
Rate of W884 to $1.00 on December 31, 1996 to W1,415 to $1.00 on December 31,
1997 and W1,418 to $1.00 on May 14, 1998) resulting from the recent economic
crisis in Korea, AICL's liabilities in won terms and its leverage calculated in
won have significantly increased in 1997. The effect of this depreciation on
AICL, however, has been mitigated by the fact that substantial amounts of AICL's
revenues are denominated in U.S. dollars. The increase in AICL's liabilities was
also attributable in part to additional financing obtained in connection with
the construction of its new wafer foundry. See "-- Risks Associated with New
Wafer Fabrication Business" and Note 6 of Notes to Combined Financial
Statements.
    
 
     The recent economic crisis in Korea has also led to sharply higher interest
rates in Korea and reduced opportunities for refinancing or refunding maturing
debts as financial institutions in Korea, which are experiencing financial
difficulties, are increasingly looking to limit their lending, particularly to
highly leveraged companies, and to increase their reserves and provisions for
non-performing assets. These developments will result in higher interest rates
on loans to AICL and have otherwise made it more difficult for AICL to obtain
new financing. Therefore, there can be no assurance that AICL will be able to
refinance its existing loans or obtain new loans, or continue to make required
interest and principal payments on such loans or otherwise comply with the terms
of its loan agreements. Any inability of AICL to obtain financing or generate
cash flow from operations sufficient to fund its capital expenditure, debt
service and repayment and other working capital and liquidity requirements could
have a material adverse effect on AICL's ability to continue to provide services
and otherwise fulfill its obligations to the Company. See "-- Risks Associated
with Leverage" and "-- Dependence on International Operations and Sales;
Concentration of Operations in the Philippines and Korea."

     As of December 31, 1997, AICL and its consolidated subsidiaries were
contingently liable under guarantees in respect of debt of AICL's
non-consolidated subsidiaries and affiliates in the Anam Group in the aggregate
amount of approximately W857 billion. As of such date, AICL had provided
guarantees for all of AUSA's debt of $319 million, the Non-Compliant Loans of
$176 million and the Company's obligations under a receivables sales
arrangement. The Company has met a significant portion of its financing needs
through financing arrangements obtained by AUSA for the benefit of the Company
based on guarantees provided by AICL. There can be no assurance that AUSA will
be able to obtain additional guarantees, if necessary, from AICL. Further, a
deterioration in AICL's financial condition could trigger defaults under AICL's
guarantees, causing acceleration of such loans. In addition, as an overseas
subsidiary of AICL, AUSA was formed with the approval of the Bank of Korea. If
the Bank of Korea were to withdraw such approval, or if AUSA otherwise ceased
operations for any reason, the Company and AICL would be required to meet their
financing needs through alternative arrangements. Although the Company believes
that alternative financing arrangements will be available in the future, there
can be no assurance that the Company or AICL will be able to obtain alternative
financing on acceptable terms or at all. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources" and Note 11 of Notes to Combined Financial Statements. In
addition, if any relevant subsidiaries or affiliates of AICL, certain of which
may have greater exposure to domestic Korean economic conditions than AICL, were
to fail to make interest or principal payments or otherwise default under their
debt obligations guaranteed by AICL, AICL could be required under its guarantees
to repay such debt, which event could have a material adverse effect on its
financial condition and results of operations.
    
 
     Historically, AICL has undertaken capacity expansion programs and other
capital expenditures primarily on the basis of forecasts of the Company and
business plans prepared jointly with the Company. The Supply Agreements
generally provide for continued capital investment by AICL based on the
Company's forecasts and operational plans prepared jointly by the Company and
AICL reflecting such forecasts. However, as a result of the recent deterioration
of the Korean economy, there can be no assurance that AICL will be able to fund
future capacity expansions and other capital investments required to supply the
Company with necessary packaging and test services and wafer output on a timely
and cost-efficient basis.
 
     The Company and AICL have historically cooperated on the development of new
package designs and packaging and testing processes and technologies. The Supply
Agreements generally provide for continued cooperation between the Company and
AICL in research and development, as well as the cross-licensing of intellectual
property rights between the Company and AICL. If the Company's relationship with
AICL were terminated for any reason, the Company's research and development
capabilities and intellectual property position could be materially and
adversely affected.
 
   
     The Company will continue to be controlled to a significant degree by James
Kim and members of his family for the foreseeable future, and Mr. Kim and other
members of his family will also continue to exercise significant influence over
the management of AICL and its affiliates. In addition, the Company and AICL
will continue to have certain contractual and other business relationships,
including under the Supply Agreements, and may engage in transactions from time
to time that are material to the Company. Although any such material agreements
and transactions would require approval of the Company's Board of Directors,
such transactions generally will not require any additional approval by a
separate committee comprised of the disinterested members of the Board of
Directors and conflicts of interest may arise in certain circumstances. There
can be no assurance that such conflicts will not from time to time be resolved
against the interests of the Company. The Company currently has four directors,
two of whom are disinterested. Under Delaware corporate law, each director owes
a duty of loyalty and care to the Company, which if breached can result in
personal liability for the directors. In addition, the Company may agree to
certain changes in its contractual and other business relationships with AICL,
including pricing, manufacturing allocation, capacity utilization and capacity
expansion, among others, which in the judgment of the Company's management will
result in reduced short-term profitability for the Company in favor of potential
long-term benefits to the Company and AICL. There can be no assurance that the
Company's business, financial condition or results of operations will not be
adversely affected by any such decision.

DEPENDENCE ON INTERNATIONAL OPERATIONS AND SALES; CONCENTRATION OF OPERATIONS IN
THE PHILIPPINES AND KOREA
 
   
     All of the production facilities currently used to fill the Company's
orders are located in the Philippines and Korea and many of the Company's
customers' operations are located in countries outside of the United States. A
substantial portion of the Company's revenues are derived from sales to
customers located outside of the United States. In 1996, 1997 and the three
months ended March 31, 1998, sales to such customers accounted for 27%, 28% and
31%, respectively, of the Company's revenues. The Company expects sales outside
of the United States to continue to represent a significant portion of its
future revenues. As a result, the Company's business will continue to be subject
to certain risks generally associated with doing business abroad, such as
foreign governmental regulations, currency fluctuations, political unrest,
disruptions or delays in shipments, currency controls and fluctuations, changes
in local economic conditions and import and export controls, as well as changes
in tax laws, tariffs and freight rates. The Company has structured its global
operations to take advantage of lower tax rates in certain countries and tax
incentives extended to encourage investment. The Company's tax returns through
1993 in the Philippines and through 1994 in the U.S. have been examined by the
Philippine and U.S. tax authorities, respectively. The recorded provisions for
subsequent open years are subject to changes upon examination by tax authorities
of tax returns for these years. Changes in the mix of income from the Company's
foreign subsidiaries, expiration of tax holidays and changes in tax laws and
regulations could result in increased effective tax rates for the Company. See
Notes 10 and 15 of Notes to Combined Financial Statements.
    
 
  Philippines
 
     The Company's results of operations and growth will be influenced by the
political situation in the Philippines and by the general state of the
Philippine economy. Although the political and economic situation in the
Philippines has stabilized in recent years, it has historically been subject to
significant instability. Most recently, the devaluation of the Philippine peso
relative to the U.S. dollar beginning in July 1997 has led to instability in the
Philippine economy. Any future economic or political disruptions or instability
or low economic growth in the Philippines could have a material adverse effect
on the Company's business, financial condition and results of operations.
Because the functional currency of the Company's Philippine operations is the
U.S. dollar, the Company has recently benefitted from cost reductions relating
to peso denominated expenditures, primarily payroll costs. The Company believes
that such devaluation of the Philippine peso will eventually lead to inflation
in the Philippines, which could offset any savings achieved to date.
 
  Korea
 
   
     In 1996, 1997 and the three months ended March 31, 1998, approximately 72%,
68% and 67%, respectively, of the Company's revenues were derived from sales of
services performed for the Company by AICL. The operations of AICL are subject
to certain risks. Relations between Korea and the Democratic People's Republic
of Korea ("North Korea") have been tense over most of Korea's history. Incidents
affecting relations between the two Koreas continually occur. No assurance can
be given that the level of tensions with North Korea will not increase or change
abruptly as a result of current or future events, which could have a material
adverse effect on AICL's, and as a result the Company's, business, financial
condition and results of operations.
    
 
     Since the beginning of 1997, Korea has experienced a significant increase
in the number and size of companies filing for corporate reorganization and
protection from their creditors. Such failures were caused by, among other
factors, excessive investments, high levels of indebtedness, weak export prices
and the Korean government's greater willingness to allow troubled corporations
to fail. As a result of such corporate failures, Korea's financial institutions
have experienced a sharp increase in non-performing loans. In addition, declines
in domestic stock prices have reduced the value of Korean banks' assets. These
developments have led international credit rating agencies to downgrade the
credit ratings of Korea, as well as various companies (including AICL) and
financial institutions in Korea.
 
   
     During the same period, the value of the won relative to the U.S. dollar
has depreciated significantly. The Market Average Exchange Rate as of May 14,
1998 was W1,418 to $1.00, as compared to the December 31,
    
 
                                       14
<PAGE>   16
 
1996 Market Average Exchange Rate of W884 to $1.00. Such depreciation of the won
relative to the U.S. dollar has increased the cost of imported goods and
services, and the value in won of Korea's public and private sector debt
denominated in U.S. dollars and other foreign currencies has also increased
significantly. Korea's foreign currency reserves also have declined
significantly. Such developments have also led to sharply higher domestic
interest rates and reduced opportunities for refinancing or refunding maturing
debts as financial institutions in Korea, which are experiencing financial
difficulties, are increasingly looking to limit their lending, in particular to
highly leveraged companies, and to increase their reserves and provisions for
non-performing assets.
 
     In order to address the liquidity crisis and the deteriorating economic
situation in Korea, the Korean government concluded an agreement with the
International Monetary Fund on December 3, 1997 pursuant to which Korea is
eligible to receive loans and other financial support reported to amount to an
aggregate of approximately $58 billion (the "IMF Financial Aid Package").
Because there are conditions on the availability of loans and other financial
support under the IMF Financial Aid Package, there can be no assurance that such
conditions will be satisfied or that such loans and other financial support will
be available. In connection with the IMF Financial Aid Package, the Korean
government announced a comprehensive policy package (the "Reform Policy")
intended to address the structural weaknesses in the Korean economy and the
financial sector. While the Reform Policy is intended to alleviate the current
economic crisis in Korea and improve the Korean economy over time, the immediate
effects could include, among others, slower economic growth, a reduction in the
availability of credit to Korean companies, an increase in interest rates, an
increase in taxes, an increased rate of inflation due to the depreciation of the
won, an increase in the number of bankruptcies of Korean companies, labor unrest
and labor strikes resulting from a possible increase in unemployment, and
political unrest. These events could have a material adverse effect on the
Korean economy. Moreover, there can be no assurance that either the IMF
Financial Aid Package or the Reform Policy will be successful. In addition,
there can be no assurance that political pressure will not force the Korean
government to retreat from some or all of its announced Reform Policy or that
the Reform Policy will be implemented as currently contemplated.
 
     The Korean government has stated that as of December 31, 1997 the total
amount of Korea's private and governmental external liabilities was $154.4
billion under IMF standards. As of December 31, 1997, the total amount of
foreign currency reserves held by Korea was $20.4 billion, of which the usable
portion (the total less amounts on deposit with overseas branches of Korean
financial institutions and swap positions between the Korean central bank and
other central banks) was $8.9 billion. Pursuant to an exchange offer concluded
in April 1998, the Korean financial institutions exchanged approximately $21.8
billion of their short-term foreign currency debt for longer term floating rate
loans guaranteed by the Korean government. In addition, the Korean government
raised approximately $4 billion through an international offering of its debt
securities in April 1998. Korean financial institutions and the Korean corporate
and public sectors continue to carry substantial amounts of debt denominated in
currencies other than the won, including short-term debt, and there can be no
assurance that there will be sufficient foreign currency reserves to repay this
debt or that this debt can be extended or refinanced.
 
     Such recent and potential future developments relating to Korea, including
the continued deterioration of the Korean economy, could have a material adverse
effect on AICL's and the Company's business, financial condition and results of
operations. See "-- Dependence on Relationship with AICL; Potential Conflicts of
Interest," "Business -- Marketing and Sales" and "-- Facilities and
Manufacturing" and Note 11 of Notes to Combined Financial Statements.
 
CUSTOMER CONCENTRATION; ABSENCE OF BACKLOG
 
   
     Due to the concentration of market share in the semiconductor industry, the
Company has been largely dependent on a small group of customers for a
substantial portion of its business. In 1995, 1996, 1997 and the three months
ended March 31, 1998, 34.1%, 39.2%, 40.1% and 34.9%, respectively, of the
Company's net revenues were derived from sales to the Company's top five
customers, with 13.3%, 23.5%, 23.4% and 19.2% of the Company's net revenues,
respectively, derived from sales to Intel Corporation ("Intel"). The ability of
the Company to maintain close, satisfactory relationships with such customers is
important to the ongoing success
    
                                       15
<PAGE>   17
 
and profitability of its business. The Company expects that it will continue to
be dependent upon a relatively limited number of customers for a significant
portion of its net revenues in future periods. None of the Company's customers
is presently obligated to purchase any amount of packaging or test services or
to provide the Company with binding forecasts of product purchases for any
period. In addition, the Company's new wafer fabrication business will be
significantly dependent upon TI. The reduction, delay, or cancellation of orders
from one of the Company's significant customers, including Intel for packaging
and test services or TI for wafer fabrication services, could materially and
adversely affect the Company's business, financial condition and results of
operations. Although the Company has received forecasts from TI which indicate
that TI will meet its minimum purchase obligation during the second half of
1998, during the first quarter of 1998 TI's orders were below such minimum
purchase commitment due to market conditions and issues encountered by TI in the
transition of its products to .18 micron technology. There can be no assurance
that such customers will not reduce, cancel or delay orders. See "-- Dependence
on the Highly Cyclical Semiconductor and Personal Computer Industries" and
"-- Risks Associated with New Wafer Fabrication Business."
 
     All of the Company's customers operate in the cyclical semiconductor
business and may vary order levels significantly from period to period. In
addition, there can be no assurance that such customers or any other customers
will continue to place orders with the Company in the future at the same levels
as in prior periods. From time to time, semiconductor companies have experienced
reduced prices for some products, as well as delays or cancellations in orders.
There can be no assurance that, should these circumstances occur in the future,
they will not adversely affect the Company's business, financial condition and
results of operations. The loss of one or more of the Company's customers, or
reduced orders by any of its key customers, could adversely affect the Company's
business, financial condition and results of operations. The Company's packaging
and test business does not typically operate with any material backlog, and the
Company expects that in the future the Company's packaging and test revenues in
any quarter will continue to be substantially dependent upon orders received in
that quarter. The Company's expense levels are based in part on its expectations
of future revenues and the Company may be unable to adjust costs in a timely
manner to compensate for any revenue shortfall. See "Business -- Marketing and
Sales."
 
EXPANSION OF MANUFACTURING CAPACITY; PROFITABILITY AFFECTED BY CAPACITY
UTILIZATION RATES
 
     The Company believes that its competitive position depends substantially on
its ability to expand its manufacturing capacity. Accordingly, although the
Company currently has available manufacturing capacity, the Company expects to
continue to make significant investments to expand such capacity, particularly
through the acquisition of capital equipment and the training of new personnel.
There can be no assurance that the Company will be able to utilize such capacity
or to continue to expand its manufacturing capacity in a timely manner, that the
cost of such expansion will not exceed management's current estimates or that
such capacity will not exceed the demand for the Company's services. In
addition, expansion of the Company's manufacturing capacity will continue to
significantly increase its fixed costs, and the Company expects to continue to
incur substantial additional depreciation and other expenses in connection with
the acquisition of new equipment and the construction of new facilities.
Increases or decreases in capacity utilization rates can have a significant
effect on gross margins since the unit cost of packaging and test services
generally decreases as fixed charges are allocated over a larger number of units
produced. Therefore, the Company's ability to maintain or enhance its gross
margins will continue to be dependent, in part, on its ability to maintain high
capacity utilization rates.
 
     Capacity utilization rates may be affected by a number of factors and
circumstances, including overall industry conditions, operating efficiencies,
the level of customer orders, mechanical failure, disruption of operations due
to expansion of operations or relocation of equipment, fire or natural
disasters, employee strikes or work stoppages or other circumstances. Although
the Company has been able to maintain a high rate of capacity utilization in
recent years as a result of its close association with its customers, its
knowledge of the semiconductor market conditions, and its continued improvements
in operating efficiencies and equipment maintenance, there can be no assurance
that this high utilization rate will be sustained in the future. The Company's
inability to generate the additional orders necessary to fully utilize its
capacity would have a material adverse effect on the Company's business,
financial condition and results of operations. For example,
 
                                       16
<PAGE>   18
 
in 1996 the Company's capacity utilization rates were negatively affected by an
unexpected downturn in the semiconductor industry. There can be no assurance
that the Company's utilization rates will not be adversely affected by future
declines in the semiconductor industry or for any other reason. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business -- Manufacturing and Facilities."
 
LIQUIDITY AND FUTURE CAPITAL REQUIREMENTS
 
     The Company plans to continue to incur substantial costs to fund its
equipment and facilities expansion plans and its packaging technology
development. The Company believes that following the application of the net
proceeds from the sale of the Common Stock and the Convertible Notes in the
Initial Public Offering, its existing cash balances, cash flow from operations,
available equipment lease financing, bank borrowings and financing obtained
through AUSA, will be sufficient to meet its projected capital expenditures,
working capital and other cash requirements for at least the next twelve months.
There can be no assurance, however, that lower than expected revenues, increased
expenses, increased costs associated with the purchase or maintenance of capital
equipment, decisions to increase planned capacity or other events will not cause
the Company to seek more capital, or capital sooner than currently expected. The
timing and amount of the Company's actual capital requirements cannot be
precisely determined and will depend on a number of factors, including demand
for the Company's services, availability of capital equipment, fluctuations in
foreign currency exchange rates, changes in semiconductor industry conditions
and competitive factors. There can be no assurance that additional financing
will be available when needed or, if available, will be available on
satisfactory terms. Failure to obtain any such financing could have a material
adverse effect on the Company. In addition, if the Company obtains such
financing by selling equity securities of the Company, the Company's
stockholders may experience significant dilution. See "-- Risks Associated with
Leverage" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."
 
RAPID TECHNOLOGICAL CHANGE; PRODUCT DEVELOPMENT
 
     The semiconductor packaging and test industry is characterized by rapid
increases in the diversity and complexity of semiconductor packaging products.
As a result, the Company expects that it will need to offer, on an ongoing
basis, more advanced package designs in order to respond to competitive industry
conditions and customer requirements. The requirement to develop and maintain
advanced packaging capabilities and equipment could require significant research
and development and capital expenditures in future years. In addition, advances
in technology also typically lead to rapid and significant price erosion and
decreased margins for older package types and may lead to products currently
being offered by the Company becoming less competitive or inventories held by
the Company becoming obsolete. The failure by the Company to achieve advances in
package design or to obtain access to advanced package designs developed by
others could have a material adverse effect on the Company's business, results
of operations and financial condition. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
     The Company's success is also dependent upon the ability of it and AICL to
develop and implement new manufacturing process and package design technologies.
Semiconductor package design and process methodologies have become increasingly
subject to technological change, requiring large expenditures for research and
development. Converting to new package designs or process methodologies could
result in delays in producing new package types which could adversely affect the
Company's ability to meet customer orders.
 
MANUFACTURING RISKS; PRODUCTION YIELDS
 
     The semiconductor packaging process is complex and involves a number of
precise steps. Defective packaging can result from a number of factors,
including the level of contaminants in the manufacturing environment, human
error, equipment malfunction, use of defective raw materials, defective plating
services and inadequate sample testing. From time to time, the Company expects
to experience lower than anticipated production yields as a result of such
factors, particularly in connection with any expansion of its capacity or change
in its processing steps. In addition, the Company's yield on new products will
be lower during the
                                       17
<PAGE>   19
 
period necessary for the Company to develop the requisite expertise and
experience in producing such products and using such processes. The failure of
the Company or AICL to maintain high quality production standards or acceptable
production yields, if significant and sustained, could result in loss of
customers, delays in shipments, increased costs, cancellation of orders and
product returns for rework, any of which could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Business -- Facilities and Manufacturing."
 
RISKS ASSOCIATED WITH NEW WAFER FABRICATION BUSINESS
 
     The Company recently began providing wafer fabrication services, with
delivery of the first products from AICL's new foundry in January 1998. Neither
the Company nor AICL has significant experience in providing wafer fabrication
services, and there can be no assurance that the Company will not experience
difficulties in marketing and selling these services or that AICL will not
encounter operational difficulties such as lower than expected yields or longer
than anticipated production ramp-up, unexpected costs and other problems in
providing these services. If the Company or AICL encounters these or similar
difficulties, the Company's and AICL's businesses, financial condition and
results of operations could be materially adversely affected. In addition, TI
has transferred certain of its CMOS processes to AICL and AICL is dependent upon
TI's assistance for developing other state-of-the-art wafer manufacturing
processes. If AICL's relationship with TI is disrupted for any reason, AICL's
ability to produce wafers would be adversely affected, thus negatively impacting
the Company's ability to fulfill its customers' orders for fabrication services,
which could materially and adversely affect the Company's business, financial
condition and results of operations. In addition, AICL's technology agreements
with TI (the "TI Technology Agreements") only cover .25 micron and .18 micron
CMOS technology and TI is not under any obligation to transfer any
next-generation technology. If AICL is not able to obtain such technology on
commercially reasonable terms or at all, the Company's ability to market AICL's
wafer fabrication services could be materially and adversely affected which
could have a material adverse effect on the Company's and AICL's business,
results of operations and financial condition.
 
     The Company's right to the supply of wafers from AICL's foundry is subject
to an agreement (the "TI Manufacturing and Purchasing Agreement") among AICL,
the Company and TI, pursuant to which TI has agreed to purchase from the Company
at least 40% of the capacity of this foundry and under certain circumstances has
the right to purchase up to 70% of this capacity. As a result, the Company's
wafer fabrication business will be significantly dependent upon TI, which may
adversely affect the Company's ability to obtain additional customers. If the
Company is unable to sell substantially all of the output of AICL's wafer
foundry, its business, results of operations and financial condition could be
materially and adversely affected. Although the Company has received forecasts
from TI which indicate that TI will meet its minimum purchase obligation during
the second half of 1998, during the first quarter of 1998 TI's orders were below
such minimum purchase commitment and it is uncertain whether TI will meet its
purchase obligations in the second quarter of 1998 due to market conditions and
issues encountered by TI in the transition of its products to .18 micron
technology. Accordingly, there can be no assurance that TI will place orders
representing at least 40% of the capacity of this foundry during this period or
in the future. A failure by TI to comply with its minimum purchase obligations
or the cancellation of a significant wafer fabrication order by TI or any other
customer could have a material adverse effect on AICL's and the Company's
business, financial condition and results of operations. The TI Manufacturing
and Purchasing Agreement terminates on December 31, 2007, unless terminated
sooner. The TI Manufacturing and Purchasing Agreement may be terminated upon two
years' prior notice by either AICL or TI if AICL and TI are unable to
successfully negotiate prior to June 30, 2000 an amendment to the TI Technology
Agreements or a new agreement with respect to AICL's use of TI's next-generation
CMOS technology. During such two-year period, TI would be obligated to purchase
a minimum of only 20% of the capacity of AICL's wafer fabrication facility. In
addition, the TI Manufacturing and Purchasing Agreement may be terminated sooner
upon, among other events, mutual written consent, material breach of the
agreement by either party, the inability of either party to obtain any necessary
government approvals, the failure of AICL to protect TI's intellectual property
and a change of control, bankruptcy, liquidation or dissolution of AICL. See
"Business -- Competition."
 
                                       18
<PAGE>   20
 
DEPENDENCE ON RAW MATERIALS SUPPLIERS AND SUBCONTRACTORS
 
     The Company obtains the direct materials for the packaging and test
services of its factories and for the packaging and test services provided by
AICL to fill the Company's orders directly from vendors. To maintain competitive
manufacturing operations, the Company must obtain from its vendors, in a timely
manner, sufficient quantities of acceptable materials at expected prices. The
Company sources most of its raw materials, including critical materials such as
lead frames and laminate substrates, from a limited group of suppliers. The
Company purchases all of its materials on a purchase order basis and has no
long-term contracts with any of its suppliers. From time to time, vendors have
extended lead times or limited the supply of required materials to the Company
because of vendor capacity constraints and, consequently, the Company has
experienced difficulty in obtaining acceptable raw materials on a timely basis.
In addition, from time to time, the Company may reject materials that do not
meet its specifications, resulting in declines in output or yield. There can be
no assurance that the Company will be able to obtain sufficient quantities of
raw materials and other supplies of an acceptable quality. The Company's
business, financial condition and results of operations could be materially and
adversely affected if its ability to obtain sufficient quantities of raw
materials and other supplies in a timely manner were substantially diminished or
if there were significant increases in the costs of raw materials that the
Company could not pass on to its customers. See "Business -- Facilities and
Manufacturing."
 
INABILITY TO OBTAIN PACKAGING AND TEST EQUIPMENT IN A TIMELY FASHION
 
     In connection with its future expansion plans, the Company and AICL expect
to purchase a significant amount of new packaging and test equipment. From time
to time, increased demand for some of this equipment causes lead times to extend
beyond those normally met by the equipment vendors. The unavailability of such
equipment or the failure of such equipment, or other equipment acquired by the
Company or AICL, to operate in accordance with the Company's or AICL's
specifications or requirements, or delays in the delivery of such equipment
could delay implementation of the Company's or AICL's expansion plans and impair
the ability of the Company to meet customer orders or otherwise have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business -- Facilities and Manufacturing."
 
MANAGEMENT OF GROWTH
 
     The Company has experienced and may continue to experience growth in the
scope and complexity of its operations and in the number of its employees. For
example, the Company is expanding its scope of operations to include wafer
fabrication services and is hiring new personnel in connection with such
expansion. This growth is expected to continue to strain the Company's
managerial, financial, manufacturing and other resources. In addition, although
the Company believes its current controls are adequate, in order to manage its
growth, the Company must continue to implement additional operating and
financial controls and hire and train additional personnel. Although the Company
has been successful in hiring and properly training sufficient numbers of
qualified personnel and in effectively managing its growth in the past, there
can be no assurance that the Company will be able to do so in the future, and
its failure to do so could have a material adverse effect on the Company's
business, financial condition and results of operations. In addition, any
failure to improve the Company's operational, financial and management systems
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "-- Risks Associated with New Wafer
Fabrication Business," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business -- Employees."
 
COMPETITION
 
     The independent semiconductor packaging and test industry is very
competitive, being comprised of approximately 50 companies with about 15 of
those companies having sales of $100 million per year or more. The Company faces
substantial competition from established packaging companies primarily located
in Asia, such as Advanced Semiconductor Engineering, Inc. (Taiwan), ASE Test
Limited (Taiwan and Malaysia),
                                       19
<PAGE>   21
 
ASAT, Ltd. (Hong Kong), Hana Microelectronics Public Co. Ltd. (Hong Kong and
Thailand), Astra International (Indonesia), Carsem Bhd. (Malaysia), ChipPAC
Incorporated (Korea), Siliconware Precision Industries Co., Ltd. (Taiwan), and
Shinko Electric Industries Co., Ltd. (Japan). Each of these companies has
significant manufacturing capacity, financial resources, research and
development operations, marketing and other capabilities, and have been
operating for some time. Such companies have also established relationships with
many large semiconductor companies which are current or potential customers of
the Company. The principal elements of competition in the independent
semiconductor packaging market include time to market, breadth of package
offering, technical competence, design services, quality, production yields,
responsiveness and customer service and price. On a larger scale, the Company
also competes with the internal manufacturing capabilities of many of its
largest customers. There can be no assurance that the Company will be able to
compete successfully in the future against existing or potential competitors or
that the Company's operating results will not be adversely affected by increased
price competition.
 
     The independent wafer fabrication business is also highly competitive. The
Company expects its wafer fabrication services to compete primarily with
independent wafer foundries such as Chartered Semiconductor Manufacturing Ltd.,
Taiwan Semiconductor Manufacturing Company Ltd. and United Microelectronics
Corporation, as well as with integrated device manufacturers such as LG Semicon
Co., Ltd., Hitachi, Ltd., Toshiba Corp. and Winbond Electronics Corporation,
which provide foundry services for other semiconductor companies. Each of these
companies has significant manufacturing capacity, financial resources, research
and development operations, marketing and other capabilities and have been
operating for some time. Many of these companies have also established
relationships with many large semiconductor companies which are current or
potential customers of the Company. The principal elements of competition in the
wafer foundry market include technology, delivery cycle times, price, product
performance, quality, production yield, responsiveness and flexibility,
reliability and the ability to design and incorporate product improvements.
There can be no assurance that the Company will be able to compete successfully
in the future against such companies. See "Business -- Competition."
 
DEPENDENCE ON KEY PERSONNEL AND AVAILABILITY OF SKILLED WORKFORCE
 
     The Company's success depends to a significant extent upon the continued
service of its key senior management and its technical personnel, each of whom
would be difficult to replace. Competition for qualified employees is intense,
and the loss of the services of any of its existing key personnel without
adequate replacement, or the inability to attract, retain and motivate qualified
new personnel could have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, in connection with
its expansion plans, the Company and AICL will be required to increase the
number of qualified engineers and other employees at their respective facilities
in the Philippines and Korea. Competition for such employees in the Philippines
and Korea is intense and the inability to attract new qualified personnel or to
retain such personnel could have a material adverse effect on the Company's
results of operations and financial condition. See "Management."
 
ENVIRONMENTAL REGULATIONS
 
     The semiconductor packaging process involves a significant amount of
chemicals and gases which are subject to extensive governmental regulations. For
example, liquid waste is produced at the stage at which silicon wafers are diced
into chips with the aid of diamond saws and cooled with running water. In
addition, excess materials on leads and moldings are removed from packaged
semiconductors in the trim and form process. The Company has installed equipment
to collect certain solvents used in connection with its manufacturing process
and has contracted with independent waste disposal companies to remove such
hazardous material.
 
     Federal, state and local regulations in the United States, as well as
environmental regulations in Korea and the Philippines, impose various controls
on the storage, handling, discharge and disposal of chemicals used in the
Company's and AICL's manufacturing process and on the facilities occupied by the
Company and AICL. The Company believes that its activities, as well as those of
AICL, conform to present environmental and land use regulations applicable to
their respective operations and current facilities. Increasing public
                                       20
<PAGE>   22
 
attention has, however, been focused on the environmental impact of
semiconductor manufacturing operations and the risk to neighbors of chemical
releases from such operations. There can be no assurance that applicable land
use and environmental regulations will not in the future impose the need for
additional capital equipment or other process requirements upon the Company or
AICL or restrict the Company's or AICL's ability to expand their respective
operations. The adoption of new ordinances or similar measures or any failure by
the Company or AICL to comply with applicable environmental and land use
regulations or to restrict the discharge of hazardous substances could subject
the Company or AICL to future liability or cause their respective manufacturing
operations to be curtailed or suspended.
 
INTELLECTUAL PROPERTY
 
     The Company currently holds 24 United States patents, five of which are
jointly held with AICL, related to various IC packaging technologies, in
addition to other pending patents. These patents will expire at various dates
from 2012 through 2016. With respect to development work undertaken jointly with
AICL, the Company and AICL share intellectual property rights under the terms of
the Supply Agreements between the Company and AICL. Such Supply Agreements also
provide for the cross-licensing of intellectual property rights between the
Company and AICL. In addition, the Company enters into agreements with other
developers of packaging technology to license or otherwise obtain certain
process or package technologies.
 
     The Company expects to continue to file patent applications when
appropriate to protect its proprietary technologies; however, the Company
believes that its continued success depends primarily on factors such as the
technological skills and innovation of its personnel rather than on its patents.
The process of seeking patent protection can be expensive and time consuming.
There can be no assurance that patents will be issued from pending or future
applications or that, if patents are issued, they will not be challenged,
invalidated or circumvented, or that rights granted thereunder will provide
meaningful protection or other commercial advantage to the Company. Moreover,
there can be no assurance that any patent rights will be upheld in the future or
that the Company will be able to preserve any of its other intellectual property
rights.
 
     Although the Company is not currently a party to any material litigation,
the semiconductor industry is characterized by frequent claims regarding patent
and other intellectual property rights. As is typical in the semiconductor
industry, the Company may receive communications from third parties asserting
patents on certain of the Company's technologies. In the event any third party
were to make a valid claim against the Company or AICL, the Company or AICL
could be required to discontinue the use of certain processes or cease the
manufacture, use, import and sale of infringing products, to pay substantial
damages and to develop non-infringing technologies or to acquire licenses to the
alleged infringed technology. The Company's business, financial condition and
results of operations could be materially and adversely affected by such
developments. Litigation, which could result in substantial cost to and
diversion of resources of the Company, may also be necessary to enforce patents
or other intellectual property rights of the Company or to defend the Company
against claimed infringement of the rights of others. The failure to obtain
necessary licenses or the occurrence of litigation relating to patent
infringement or other intellectual property matters could have a material
adverse effect on the Company's business, financial condition and results of
operations. In addition, AICL has obtained intellectual property for wafer
manufacturing primarily from TI. The licenses granted to AICL by TI under the TI
Technology Agreements are very limited. Although TI has granted to AICL a
license under TI's trade secret rights to use TI's technology in connection with
AICL's provision of wafer fabrication services, TI has not granted AICL a
license under its patents, copyrights and mask works to manufacture
semiconductors for third parties. Although TI has agreed that TI will not assert
a claim for patent, copyright or mask work right infringement against AICL or
the Company in connection with AICL's manufacture of semiconductor products for
third parties, TI has reserved the right to bring such infringement claims
against AICL's or the Company's customers with respect to semiconductor products
purchased from AICL or the Company. As a result, AICL's and the Company's
customers could be subject to patent litigation by TI and others, and AICL and
the Company could in turn be subject to litigation by such customers and others,
in connection with the sale of wafers produced by AICL. Any such litigation
could materially and adversely affect AICL's ability to continue to manufacture
wafers and AICL's and the Company's business, financial condition and results of
operations.

NO PRIOR MARKET; LIQUIDITY; STOCK PRICE VOLATILITY
 
   
     Prior to the Initial Public Offering, there had been no public market for
the Common Stock. Although the Underwriters for the Initial Public Offering have
advised the Company that they intended to make a market in the Common Stock,
they are not obligated to do so and may discontinue such market-making at any
time without notice. There can be no assurance that an active public market for
the Common Stock will be sustained after the Initial Public Offering or that the
market price of the Common Stock will not decline. The trading price of the
Common Stock could be subject to wide fluctuations in response to
quarter-to-quarter variations in operating results, announcements of
technological innovations or new products by the Company or its competitors,
general conditions in the semiconductor industry, changes in earnings estimates
or recommendations by analysts, or other events or factors. In addition, the
public stock markets have experienced extreme price and trading volume
volatility in recent months. This volatility has significantly affected the
market prices of securities of many high technology companies for reasons
frequently unrelated to the operating performance of the specific companies.
These broad market fluctuations may adversely affect the market price of the
Common Stock.
    
 
BENEFITS OF THE INITIAL PUBLIC OFFERING TO EXISTING STOCKHOLDERS; CONTINUED
CONTROL BY EXISTING STOCKHOLDERS
 
   
     Immediately after the closing of the Initial Public Offering, based upon
shares outstanding as of the date hereof, James Kim and members of his family
beneficially owned in the aggregate 77,610,000 shares of Common Stock, which
shares represented all of the outstanding Common Stock not offered in the
Initial Public Offering and approximately 65.8% of the total number of shares of
Common Stock outstanding following the Initial Public Offering. The Initial
Public Offering created a public market for the resale of shares held by these
existing stockholders. Such stockholders, acting together, will be able to
effectively control substantially all matters requiring approval by the
stockholders of the Company. Such matters could include the election of a
majority of the members of the Board of Directors, proxy contests, mergers
involving the Company, tender offers, open market purchase programs or other
purchases of Common Stock that could give stockholders of the Company the
opportunity to realize a premium over the then prevailing market price for their
shares of Common Stock. In addition, such continued control could also have the
effect of delaying, deferring or preventing a change in control of the Company,
may discourage bids for the Common Stock at a premium over the market price and
may adversely affect the market price of the Common Stock. See "Principal
Stockholders."
    
 
ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
     The Company's Board of Directors has the authority to issue up to
10,000,000 shares of preferred stock $.001 par value ("Preferred Stock") and to
determine the price, rights, preferences and privileges of those shares without
any further vote or action by the Company's stockholders. The rights of the
holders of Common Stock will be subject to, and may be adversely affected by,
the rights of the holders of any Preferred Stock that may be issued in the
future. While the Company has no present intention to issue shares of Preferred
Stock, such issuance, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
making it more difficult for a third party to acquire a majority of the
outstanding voting stock of the Company. In addition, the Company is subject to
the anti-takeover provisions of Section 203 of the Delaware General Corporation
Law, which prohibits the Company from engaging in a "business combination" with
an "interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. The application of
Section 203 could have the effect of delaying or preventing a change of control
of the Company. The Company's Certificate of Incorporation (the "Certificate of
Incorporation") does not permit cumulative voting. This provision, and other
provisions of the Certificate of Incorporation, the Company's bylaws (the
"Bylaws") and Delaware corporate law, may have the effect of deterring hostile
takeovers or delaying or preventing changes in control or management of the
Company, including transactions in which stockholders might otherwise receive a
premium for their shares over then current market prices.

SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Sales of substantial amounts of Common Stock into the public market could
adversely affect the prevailing market price of the Common Stock. In addition to
the up to 7,000,000 shares of Common Stock that may be offered hereby from time
to time, there were an additional 40,250,000 shares of Common Stock which were
sold to the public in the Initial Public Offering, and there will be 15,333,333
shares issuable upon conversion of the Convertible Notes, all of which shares
are freely tradeable. Excluding the shares described above, there are
approximately 70,610,000 additional shares of Common Stock outstanding, all of
which are "restricted" shares (the "Restricted Shares") under the Securities Act
of 1933, as amended (the "Securities Act"). Beginning April 29, 1999, all such
Restricted Shares will first become eligible for sale in the public market
pursuant to Rule 144 promulgated under the Securities Act, subject to certain
volume and other resale restrictions pursuant to Rule 144. See "Shares Eligible
for Future Sale."

                                 REORGANIZATION
 
     In March 1970, Amkor Electronics, Inc. ("AEI") was incorporated in
Pennsylvania to design semiconductor packages and provide semiconductor
packaging services through a supply relationship with AICL. Since that time, Mr.
James Kim (the founder of AEI) and members of his family have acquired a
majority interest in a number of other companies which support or engage in
various aspects of the semiconductor packaging and test business (the "Amkor
Companies"). Prior to the reorganization described below, the Amkor Companies
consisted of:
 
     - AEI and its subsidiaries Amkor Receivables Corp., which purchases the
       Company's accounts receivable under an accounts receivable financing
       arrangement, and Amkor Wafer Fabrication Services SARL, which provides
       various technical support for CIL's wafer fabrication services customers
       in Europe and Asia;
 
     - T.L. Limited ("TLL") and its subsidiary C.I.L. Limited ("CIL"), which
       markets the Company's services to semiconductor companies in Europe and
       Asia;
 
     - Amkor/Anam EuroServices S.A.R.L. ("AAES"), which provides various
       technical and support services for CIL's packaging and test customers;
 
     - Amkor/Anam Advanced Packaging, Inc. ("AAAP"), Amkor/Anam Pilipinas, Inc.
       ("AAP") and AAP's subsidiary Automated MicroElectronics Inc. ("AMI"),
       each of which provides manufacturing services; and
 
     - AK Industries, Inc. ("AKI") and its subsidiary, Amkor-Anam, Inc., which
       provides raw material purchasing and inventory management services.
 
   
     All of the Amkor Companies were substantially wholly owned beneficially by
Mr. and Mrs. Kim or entities beneficially owned by members of Mr. James Kim's
immediate family (the "Founding Stockholders"), except for 40% of AAP owned by
AICL and one-third of AEI and all of AKI which were owned by certain trusts
established for the benefit of other members of Mr. Kim's family (the "Kim
Family Trusts"). The Company (Amkor Technology, Inc.) was formed in September
1997 to consolidate the ownership of the Amkor Companies. Prior to the
reorganization described below, Amkor Technology, Inc. conducted no business and
held no assets or liabilities.
    
 
     Prior to the Initial Public Offering, the following transactions were
effected to consolidate the operations of the Amkor Companies under the Company,
(such transactions are referred to collectively as the "Reorganization"):
 
     - AEI was merged into Amkor Technology, Inc.
 
     - Amkor International Holdings ("AIH"), a newly formed Cayman Islands
       holding company, became a wholly-owned subsidiary of Amkor Technology,
       Inc. holding the following entities:
          - First Amkor Cayman Islands, Ltd., a newly formed Cayman Islands
            holding company, and its subsidiaries AAAP, AAP and AMI;
          - TLL and its subsidiary CIL; and
          - AAES.
 
     - In addition, the Company acquired all of the stock of AKI from the Kim
       Family Trusts for $3 million.
 
   
     Except for the acquisition of AKI which has been accounted for as a
purchase transaction, the accounting for the Reorganization is similar to the
accounting for a pooling of interests as it represents an exchange of equity
interests among companies under common control. All of the Amkor Companies are
wholly owned, directly or indirectly, by the Company (except for AAP, which is
40% owned by AICL). An aggregate of 82,610,000 shares of Common Stock were
issued by the Company in connection with the Reorganization. The relative number
of shares of Common Stock issued by the Company in connection with each of the
transactions comprising the Reorganization was based upon relative amounts of
stockholders' equity of each of the Amkor Companies as of December 31, 1997.
Accordingly, the Company issued an aggregate of 14,620,140 shares of Common
Stock in connection with the merger of AEI into Amkor Technology, Inc.,
two-thirds of
    
                                       24

which (9,746,760 shares) were received by Mr. and Mrs. Kim and one-third of
which (4,873,380 shares) were received by the Kim Family Trusts. The Company
then issued an aggregate of 67,989,851 shares of Common Stock, representing
approximately 82% of its shares immediately after the Reorganization, in
exchange for all of the outstanding shares of AIH and its subsidiaries. Of such
shares, 27,528,234 shares and 36,376,617 shares were gifted to Mr. and Mrs. Kim
and the Kim Family Trusts, respectively, such that Mr. and Mrs. James Kim and
the Kim Family Trusts owned 45.1% and 49.9%, respectively, of the Common Stock
outstanding after the Reorganization. Following the Reorganization, the Founding
Stockholders beneficially owned a majority of the outstanding shares of Common
Stock. Following the Initial Public Offering, the Founding Stockholders and the
Kim Family Trusts beneficially owned 77,610,000 shares of Common Stock,
representing approximately 65.8% of the outstanding shares of Common Stock. See
"Certain Transactions" and "Principal Stockholders."
    
 
     The Company has entered into an agreement with AICL pursuant to which the
Company will purchase, immediately following the Initial Public Offering, AICL's
40% interest in AAP for approximately $34 million. See "Prospectus
Summary -- The Initial Public Offering."
 
   
TERMINATION OF S CORPORATION STATUS AND DISTRIBUTIONS
    
 
   
     Prior to the consummation of the Reorganization, AEI had elected to be
treated for U.S. federal and certain state tax purposes as an S Corporation
under the Internal Revenue Code of 1986 and comparable state tax laws. As a
result, AEI did not recognize federal corporate income taxes. Instead, up until
the termination of AEI's S Corporation status on April 28, 1998 (the
"Termination Date"), Mr. and Mrs. Kim and the Kim Family Trusts had been
obligated to pay U.S. federal and certain state income taxes on their allocable
portion of the income of AEI. The Company, Mr. and Mrs. Kim and the Kim Family
Trusts have entered into tax indemnification agreements providing that the
Company will be indemnified by such stockholders, with respect to their
proportionate share of any U.S. federal or state corporate income taxes
attributable to the failure of AEI to qualify as an S Corporation for any period
or in any jurisdiction for which S Corporation status was claimed through the
Termination Date. The tax indemnification agreements also provide that under
certain circumstances the Company will indemnify Mr. and Mrs. Kim and the Kim
Family Trusts if such stockholders are required to pay additional taxes or other
amounts attributable to taxable years on or before the Termination Date as to
which AEI filed or files tax returns claiming status as an S Corporation. AEI
has made various distributions to such stockholders which have enabled them to
pay their income taxes on their allocable portions of the income of AEI. Such
distributions totaled approximately $19.8 million, $13.0 million and $5.0
million in 1995, 1996 and 1997, respectively. No amounts were distributed during
the three months ended March 31, 1998. The Company declared additional
distributions to such stockholders prior to the consummation of the
Reorganization in an amount equal to AEI's amd Amkor Technology, Inc.'s
cumulative net income in all periods prior to the Termination Date less the
aggregate amount of distributions previously made to such stockholders. These
final distributions are intended to provide such stockholders with the balance
of AEI's and Amkor Technology, Inc.'s net income for which they have already
recognized taxable income. Through March 31, 1998, the amount of such
undistributed net income was $35.7 million. Subsequent to March 31, 1998,
aggregate distributions of $33.1 million were made to such stockholders. See
Notes 1, 10 and 17 of Notes to Combined Financial Statements.

                             RELATIONSHIP WITH AICL
 
     AICL is a Korean company engaged primarily in providing semiconductor
packaging and test services to the Company, which in turn sells such services to
its customers. AICL also currently markets its services directly in Korea. In
addition, AICL manufactures and sells electric wiring devices and watches. AICL
operates four semiconductor packaging and test facilities in Korea, and has
recently qualified a new deep submicron CMOS wafer foundry in Korea which is
currently capable of producing 15,000 8" wafers per month. In March 1998, AICL
changed its name to Anam Semiconductor, Inc.
 
   
     AICL was founded in 1956 by Mr. H. S. Kim, who currently serves as the
honorary Chairman and a Representative Director of AICL. AICL is a member of the
Anam Group, consisting principally of companies in Korea in the electronics
industries. The businesses of AICL and the other companies in the Anam Group are
influenced to a significant degree by the family of H. S. Kim, which, together
with the Company, collectively owned approximately 40.7% of the outstanding
common stock of AICL as of December 31, 1997. A significant portion of the
shares owned by the Kim family are leveraged and as a result of this, or for
other reasons, the family's ownership could be substantially reduced. James Kim,
the founder of the Company and currently its Chairman and Chief Executive
Officer, is the eldest son of H. S. Kim. Since January 1992, in addition to his
other responsibilities, James Kim has been serving as acting Chairman of the
Anam Group and a director of AICL. Mr. In-Kil Hwang, the President and a
Representative Director of AICL, is the brother-in-law of James Kim. In
addition, four other members of Mr. Kim's family are on the 13 member Board of
Directors of AICL. After the Initial Public Offering, James Kim and members of
his family beneficially owned approximately 65.8% of the outstanding Common
Stock of the Company, and Mr. Kim and other members of his family will continue
to exercise significant control over the Company. See "Risk Factors -- Benefits
of the Initial Public Offering to Existing Stockholders; Continued Control by
Existing Stockholders" and "Principal Stockholders."
    
 
   
     The businesses of the Company and AICL have been interdependent for many
years. In 1996, 1997 and the three months ended March 31, 1998, approximately
72%, 68% and 67%, respectively, of the Company's revenues were derived from
sales of services performed for the Company by AICL. In addition, substantially
all of the revenues of AICL in 1996, 1997 and the three months ended March 31,
1998 were derived from services sold by the Company. The Company expects the
proportion of its revenues derived from sales of services performed for the
Company by AICL and the proportion of AICL's revenues from services sold by the
Company to increase as the Company begins selling the wafer fabrication output
of AICL's new wafer foundry and with the Company's assumption from AICL in
January 1998 of substantially all of the marketing rights for the Japanese
market. In the event the ability of AICL to supply the Company were disrupted
for any reason, the Company's facilities in the Philippines would be able to
fill only a small portion of the resulting shortfall in capacity. In addition,
there are currently no significant third party suppliers of packaging and test
services from which the Company could fill its orders. As a result, the
Company's business, financial condition and operating results will continue to
be significantly dependent on the ability of AICL to effectively provide
contracted services on a cost-efficient and timely basis. The Company expects
that the businesses of the Company and AICL will continue to remain highly
interdependent by virtue of their supply relationship, family ties between their
respective shareholders and management, financial relationships, coordination of
product and operation plans, joint research and development activities and
shared intellectual property rights. The termination of the Company's
relationship with AICL for any reason, or any material adverse change in AICL's
business resulting from underutilization of its capacity, the level of its debt
and its guarantees of affiliate debt, labor disruptions, fluctuations in foreign
exchange rates, changes in governmental policies, economic or political
conditions in Korea or any other change, could have a material adverse effect on
the Company's business, financial condition and results of operations.
    
 
     The Company has recently entered into the Supply Agreements with AICL.
Under the Supply Agreements, AICL has granted to the Company a first right to
substantially all of the packaging and test services of AICL and the exclusive
right to all of the wafer output of its new wafer foundry. The Company expects
to continue to purchase substantially all of AICL's packaging and test services,
and to purchase all of AICL's wafer output, under the Supply Agreements. Under
the Supply Agreements, pricing arrangements relating to packaging and test
services provided by AICL to the Company are subject to quarterly review and
adjustment,
                                       26
<PAGE>   28
 
and such arrangements relating to the wafer output provided by AICL to the
Company are subject to annual review and adjustment, in each case on the basis
of factors such as changes in the semiconductor market, forecasted demand,
product mix and capacity utilization and fluctuations in exchange rates, as well
as the mutual long-term strategic interests of the Company and AICL. There can
be no assurance that any new pricing arrangements resulting from such review and
adjustment will be favorable to the Company. Pursuant to long-standing
arrangements between AICL and the Company's operating subsidiaries, sales from
AICL to the Company will continue to be made through AUSA, a wholly-owned
financing subsidiary of AICL. Under the Supply Agreements, the Company will
continue to reimburse AUSA for the financing costs incurred by it in connection
with trade financing provided to the Company. The Supply Agreements also provide
that Amkor-Anam, Inc., a subsidiary of the Company, will continue to provide raw
material procurement and related services to AICL on a fee basis. The Supply
Agreements have a five-year term, and may be terminated by any party thereto
upon five years' written notice at any time after the expiration of such initial
five-year term. There can be no assurance that AICL will not terminate either
Supply Agreement upon the expiration of such initial term or that if it does
terminate a Supply Agreement, that the Company will be able to obtain a new
agreement with AICL on terms that are favorable to the Company or at all.
 
     AICL's ability to continue to provide services to the Company will depend
on AICL's financial condition and performance. AICL currently has a significant
amount of debt relative to its equity, which debt the Company expects will
continue to increase in the foreseeable future. The Company is advised that
AICL, as a public company in Korea, has published its most recent consolidated
financial statements as of and for the year ended December 31, 1997. These
consolidated financial statements are prepared on the basis of Korean GAAP,
which differs significantly from U.S. GAAP. U.S. GAAP financial statements are
not available. The independent auditors' report regarding AICL, included
elsewhere in this Prospectus, includes an explanatory paragraph regarding change
in accounting principles, the impact of the Korean economic situation on AICL
and its ability to continue as a going concern.

</TABLE>
 
   
     A significant amount of the current and long-term liabilities of AICL are
denominated in U.S. dollars and other foreign currencies. At December 31, 1997,
the amount of U.S. dollar and other foreign currency denominated short-term
borrowings, current maturities of long-term debt, long-term debt (net of current
maturities) and long-term capital lease obligations were W1,222 billion, W59
billion, W159 billion and W834 billion, respectively. Due in part to the
significant depreciation of the won (for example, from a Market Average Exchange
Rate of W884 to $1.00 on December 31, 1996 to W1,415 to $1.00 on December 31,
1997 and W1,418 to $1.00 on May 14, 1998) resulting from the recent economic
crisis in Korea, AICL's liabilities in won terms and its leverage calculated in
won have significantly increased in 1997. The effect of this depreciation on
AICL, however, has been mitigated by the fact that substantial amounts of AICL's
revenues are denominated in U.S. dollars. The increase in AICL's liabilities was
also attributable in part to additional financing obtained in connection with

Wafer Fabrication Business" and Note 6 of Notes to Combined Financial

     The recent economic crisis in Korea has also led to sharply higher domestic
interest rates in Korea and reduced opportunities for refinancing or refunding
maturing debts as financial institutions in Korea, which are experiencing
financial difficulties, are increasingly looking to limit their lending,
particularly to highly leveraged companies, and to increase their reserves and
provisions for non-performing assets. These developments will result in higher
interest rates on loans to AICL and have otherwise made it more difficult for
AICL to obtain new financing. Therefore, there can be no assurance that AICL
will be able to refinance its existing loans or obtain new loans, or continue to
make required interest and principal payments on such loans or otherwise comply
with the terms of its loan agreements. Any inability of AICL to obtain financing
or generate cash flow from operations sufficient to fund its capital
expenditure, debt service and repayment and other working capital and liquidity
requirements could have a material adverse effect on AICL's ability to
 
                                       29

continue to provide services and otherwise fulfill its obligations to the
Company. See "Risk Factors -- Risks Associated With Leverage" and
" -- Dependence On International Operations and Sales; Concentration of
Operations in the Philippines and Korea."
 
   
     As of December 31, 1997, AICL and its consolidated subsidiaries were
contingently liable under guarantees in respect of debt of AICL's
non-consolidated subsidiaries and affiliates in the Anam Group in the aggregate
amount of approximately W857 billion. As of such date, AICL had provided
guarantees for all of AUSA's debt of $319 million, the Non-Compliant Loans of
$176 million and the Company's obligations under a receivables sales
arrangement. The Company has met a significant portion of its financing needs
through financing arrangements obtained by AUSA for the benefit of the Company,
based on guarantees provided by AICL. There can be no assurance that AUSA will
be able to obtain additional guarantees, if necessary, from AICL. Further, a
deterioration in AICL's financial condition could trigger defaults under AICL's
guarantees, causing acceleration of such loans. In addition, as an overseas
subsidiary of AICL, AUSA was formed with the approval of the Bank of Korea. If
the Bank of Korea were to withdraw such approval, or if AUSA otherwise ceased
operations for any reason, the Company and AICL would be required to meet their
financing needs through alternative arrangements. Although the Company believes
that alternative financing arrangements will be available in the future, there
can be no assurance that the Company or AICL will be able to obtain alternative
financing on acceptable terms or at all. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources" and Note 11 of Notes to Combined Financial Statements. In
addition, if any relevant subsidiaries or affiliates of AICL, certain of which
may have greater exposure to domestic Korean economic conditions than AICL, were
to fail to make interest or principal payments or otherwise default under their
debt obligations guaranteed by AICL, AICL could be required under its guarantees
to repay such debt, which event could have a material adverse effect on its
financial condition and results of operations.
    
 
     Historically, AICL has undertaken capacity expansion programs and other
capital expenditures primarily on the basis of forecasts of the Company and
business plans prepared jointly with the Company. The Supply Agreements
generally provide for continued capital investment by AICL based on the
Company's forecasts and operational plans prepared jointly by the Company and
AICL reflecting such forecasts. However, as a result of the recent deterioration
of the Korean economy, there can be no assurance that AICL will be able to fund
future capacity expansions and other capital investments required to supply the
Company with necessary packaging and test services and wafer output on a timely
and cost-efficient basis.
 
     The Company and AICL have historically cooperated on the development of new
package designs and packaging and testing processes and technologies. The Supply
Agreements generally provide for continued cooperation between the Company and
AICL in research and development, as well as the cross-licensing of intellectual
property rights between the Company and AICL. If the Company's relationship with
AICL were terminated for any reason, the Company's research and development
capabilities and intellectual property position could be materially and
adversely affected.
 
   
     The Company will continue to be controlled to a significant degree by James
Kim and members of his family for the foreseeable future, and Mr. Kim and other
members of his family will continue to exercise significant influence over the
management of AICL and its affiliates. In addition, the Company and AICL will
continue to have certain contractual and other business relationships, including
under the Supply Agreements, and may engage in transactions from time to time
that are material to the Company. Although any such material agreements and
transactions would require approval of the Company's Board of Directors, such
transactions generally will not require any additional approval by a separate
committee comprised of the disinterested members of the Board of Directors and
conflicts of interest may arise in certain circumstances. There can be no
assurance that such conflicts will not from time to time be resolved against the
interests of the Company. The Company currently has four directors, two of whom
are disinterested. Under Delaware corporate law, each director owes a duty of
loyalty and care to the Company, which if breached can result in personal
liability for the directors. In addition, the Company may agree to certain
changes in its contractual
    
 
                                       30
<PAGE>   32
 
and other business relationships with AICL, including pricing, manufacturing
allocation, capacity utilization and capacity expansion, among others, which in
the judgment of the Company's management will result in reduced short-term
profitability for the Company in favor of potential long-term benefits to the
Company and AICL. There can be no assurance that the Company's business,
financial condition or results of operations will not be adversely affected by
any such decision.
 
                                USE OF PROCEEDS
 
     This Prospectus relates to the shares of Common Stock which Salomon Smith
Barney may, subject to certain limitations, from time to time, borrow from Mr.
and Mrs. Kim to settle short sales of Common Stock (or to return Common Stock
previously borrowed by Salomon Smith Barney to settle such short sales) entered
into by Salomon Smith Barney to hedge any long position in the Convertible Notes
resulting from its market-making activities. See "Plan of Distribution." The
Company will not receive any proceeds from the sale of the Common Stock to which
this Prospectus relates.
 
                                DIVIDEND POLICY
 
     The Company currently anticipates that all future earnings will be retained
for use in the Company's business and that the Company will not pay any cash
dividends on its Common Stock in the foreseeable future. The payment of any
future dividends will be at the discretion of the Company's Board of Directors
and will depend upon, among other things, future earnings, operations, capital
requirements, the general financial condition of the Company and general
business conditions. As an S Corporation, AEI made substantial cash
distributions to its stockholders to pay income taxes on their allocable
portions of AEI's net income. The Company plans to make additional distributions
to such stockholders prior to the Termination Date. See "Reorganization."

(1) Pro forma balance sheet data reflects (i) the termination of AEI's S
    Corporation status which resulted in the recording of a deferred tax asset
    of $1.5 million and (ii) a distribution by the Company of undistributed
    earnings of AEI through March 31, 1998 of $35.7 million to stockholders of
    AEI prior to the Reorganization. The amount actually distributed by the
    Company to such stockholders of AEI will reflect the amount of undistributed
    net income (loss) recognized by AEI and Amkor Technology, Inc. following
    March 31, 1998 and prior to the Reorganization. See

    its 40% interest in AAP for approximately $34 million and the related
    elimination of minority interest and recording of goodwill. The acquisition
    of the minority interest will result in additional amortization of
    approximately $2.5 million per year. Also reflects repayments made after

(1) Prior to the Reorganization, AEI, a predecessor of the Company, elected to
    be taxed as an S Corporation under the Internal Revenue Code of 1986 and
    comparable state tax laws. Accordingly, AEI did not recognize any provision
    for federal income tax expense during the periods presented. The pro forma
    provision for income taxes reflects the additional U.S. federal income taxes
    which would have been recorded if AEI had not been an S Corporation during
    these periods. See "Reorganization" and Note 1 of Notes to Combined
    Financial Statements.
 
(2) EBITDA is defined as earnings before interest income, interest expense,
    taxes on income, depreciation and amortization. EBITDA is presented here to
    provide additional information about the Company's ability to meet its
    future debt service, capital expenditure, and working capital requirements
    and should not be construed as a substitute for or a better indicator of
    results of operations or liquidity than net income or cash flow from
    operating activities computed in accordance with generally accepted
    accounting principles.
 
   
(3) For purposes of computing the ratio of earnings to fixed charges, earnings
    consist of income before income taxes less undistributed earnings in less
    than 50%-owned subsidiaries, plus fixed charges. Fixed charges consist of
    interest expense incurred and one-third of rental expense which amount is
    deemed by the Company to be representative of the interest factor of rental
    payments under operating leases. The supplemental pro forma ratio of
    earnings to fixed charges reflects the effect on the ratio of earnings to
    fixed charges as if the Initial Public Offering had been completed and the
    net proceeds to the Company applied as described in "Prospectus
    Summary -- The Initial Public Offering" at the beginning of the period
    presented.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
     The following discussion contains forward-looking statements within the
meaning of the federal securities laws, including statements regarding the
anticipated growth in the market for the Company's products, the Company's
anticipated capital expenditures and financing needs, the Company's expected
capacity utilization rates, the belief of the Company as to its future operating
performance and other statements that are not historical facts. 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" and "Business." The following discussion provides information and
analysis of the Company's results of operations from 1995 through 1997 and the
three months ended March 31, 1998 and its liquidity and capital resources and
should be read in conjunction with the Combined Financial Statements and Notes
thereto and the selected combined financial data included elsewhere in this
Prospectus. The operating results for interim periods are not necessarily
indicative of results for any subsequent period.
    
 
OVERVIEW
 
     Background. The Company is the world's largest independent provider of
semiconductor packaging and test services. The Company believes that it is also
one of the leading developers of advanced semiconductor packaging and test
technology in the industry. The Company offers a complete and integrated set of
packaging and test services including IC package design, leadframe and substrate
design, IC package assembly, final testing, burn-in, reliability testing, and
thermal and electrical characterization. The Company recently began offering
wafer fabrication services. The Company provides packaging and test services
through its three factories in the Philippines (P1, P2 and P3) as well as the
four factories of AICL in Korea, and wafer fabrication services through AICL's
new wafer foundry, pursuant to the Supply Agreements between the Company and
AICL. As of December 31, 1997, the Company had in excess of 150 customers,
including many of the largest semiconductor companies in the world.
 
     The Company was formed in September 1997 to consolidate the operations of
the Amkor Companies, including AEI which was incorporated in 1970. These
companies were under common management and in the same business prior to the
Company's formation. As a result of the Reorganization, the financial statements
included in this Prospectus are presented on a combined basis. See
"Reorganization" and "Certain Transactions" and Notes 1 and 16 of Notes to
Combined Financial Statements. Prior to the Reorganization, AEI elected to be
taxed as an S Corporation under the Internal Revenue Code of 1986 and comparable
state tax laws. Accordingly, AEI did not recognize any provision for federal
income tax expense during the periods presented in the Combined Financial
Statements. The Combined Financial Statements include a pro forma provision for
income taxes which reflects the U.S. federal income taxes which would have been
recorded by the Company if AEI had not been an S Corporation during these
periods. See Notes 1, 10 and 17 of Notes to Combined Financial Statements.
 
     General.  From 1995 to 1997, the Company's revenues increased from
approximately $932.4 million to $1.456 billion. This increase occurred primarily
as a result of increases in unit volumes, together with the shift in the
Company's product mix from traditional leadframe products to advanced leadframe
and laminate products, which were offset in part by decreasing average selling
prices. See "Business -- Products." In order to meet customer demand, the
Company has invested significant resources to expand its capacity in the
Philippines. In 1996 and the first six months of 1997, the Company incurred and
expensed $15.5 million and $16.6 million, respectively, of pre-operating and
start-up costs and initial operating losses in connection with its newest
factory, P3, in the Philippines. This facility operated at substantially less
than full capacity during these periods while customers were completing
qualification procedures for BGA packages to be produced at the facility. The
Company significantly increased utilization of P3 during the last six months of
1997 and expects to operate the facility with positive gross margins during
1998. See "Risk Factors -- Expansion of Manufacturing Capacity; Profitability
Affected by Capacity Utilization Rates" and "Business -- Facilities and
Manufacturing."
 
   
     The Company's results of operations are generally affected by the
capital-intensive nature of its business. In 1995, 1996, 1997 and the three
months ended March 31, 1998, the Company invested $123.6 million,
    
 
                                       36
<PAGE>   38
 
   
$185.1 million, $179.0 million and $33.7 million, respectively, in property,
plant and equipment. Increases or decreases in capacity utilization rates can
have a significant effect on gross margins since the unit cost of packaging and
test services generally decrease as fixed charges, such as depreciation expense
for the equipment, are allocated over a larger number of units produced. In
addition, the Company's gross margin is significantly affected by fluctuations
in service charges paid to AICL pursuant to the Supply Agreements. Pricing
arrangements relating to packaging and test services provided by AICL to the
Company are subject to quarterly review and adjustment, and pricing arrangements
relating to wafer fabrication services provided by AICL are subject to annual
review and adjustment, in each case on the basis of factors such as changes in
the semiconductor market, forecasted demand, product mix and capacity
utilization and fluctuations in exchange rates, as well as the mutual long-term
strategic interest of the Company and AICL. The Company's results of operations
are also affected by declines over time in the average selling prices for
particular products. At times in the past the Company has been able to offset,
at least in part, the effect of such decline on its margins by successfully
developing and marketing new products with higher margins, such as advanced
leadframe and laminate products, and by taking advantage of economies of scale
and higher productivity resulting from volume production. However, there can be
no assurance that the Company will be successful at offsetting any such declines
in the future. See "Risk Factors -- Expansion of Manufacturing Capacity;
Profitability Affected by Capacity Utilization Rates" and "-- Competition."
    
 
   
     Due to the concentration of market share in the semiconductor industry, the
Company has been largely dependent upon a small group of customers for a
substantial portion of its business. In 1995, 1996, 1997 and the three months
ended March 31, 1998, 34.1%, 39.2%, 40.1%, and 34.9%, respectively, of the
Company's net revenues were derived from sales to the Company's top five
customers, with 13.3%, 23.5%, 23.4% and 19.2%, respectively, derived from sales
to Intel. See "Risk Factors -- Customer Concentration; Absence of Backlog."
    
 
   
     Relationship with AICL. In 1996, 1997 and the three months ended March 31,
1998, approximately 72%, 68% and 67%, respectively, of the Company's revenues
were derived from sales of services performed for the Company by AICL. In
addition, substantially all of the revenues of AICL in 1996, 1997 and the three
months ended March 31, 1998 were derived from services sold by the Company.
Historically, AICL has directly sold packaging and test services in Japan and
Korea. The Company assumed substantially all of the marketing rights for
services in Japan in January 1998. Also, the Company recently began offering
wafer fabrication services through AICL's new deep submicron CMOS foundry which
is capable of producing up to 15,000 8" wafers per month. See "Risk
Factors -- Risks Associated with New Wafer Fabrication Business." The Company
expects the proportion of its net revenues derived from sales of services
performed for the Company by AICL and the percentage of AICL's revenues from
services sold by the Company to increase as the Company begins selling the wafer
fabrication output of AICL's new wafer foundry and with the Company's assumption
from AICL of substantially all of the marketing rights for Japan. The Company
has a first right to substantially all of the packaging and test service
capacity of AICL and the exclusive right to all of the wafer output of AICL's
new wafer foundry.
    
 
     The Supply Agreements between the Company and AICL generally provide, among
other things, for periodic price reviews and adjustments and coordination of
research and development efforts regarding package design and packaging and
testing processes and technologies. The Supply Agreements have a five year
initial term and thereafter may be terminated upon five years' notice. There can
be no assurance that AICL will not terminate either Supply Agreement upon the
expiration of such initial term, or that if it does terminate a Supply
Agreement, that the Company will be able to enter into a new agreement with AICL
on terms favorable to the Company or at all. See "Relationship with AICL."
 
     The Company expects that the businesses of the Company and AICL will
continue to remain highly interdependent by virtue of their supply relationship,
overlaps and family ties between their respective shareholders and management,
financial relationships, coordination of product and operation plans, joint
research and development activities and shared intellectual property rights. As
a result, the Company's business, financial condition and operating results will
continue to be significantly dependent on AICL, including without limitation
AICL's ability to effectively provide the contracted services on a
cost-efficient and timely basis as well as AICL's financial condition and
results of operations. The Company will continue to be controlled to a
significant degree by James Kim and members of his family, and Mr. Kim and other
members of his family will also continue to exercise significant influence over
the management of AICL and
 
                                       37
<PAGE>   39
 
its affiliates. In addition, the Company and AICL will continue to have certain
contractual and other business relationships and may engage in transactions from
time to time that are material to the Company. Although any such material
agreements and transactions would require approval of the Company's Board of
Directors, such transactions will generally not require any additional approval
by a separate committee comprised of the disinterested members of the Board of
Directors and conflicts of interest may arise in certain circumstances. There
can be no assurance that such conflicts will not from time to time be resolved
against the interests of the Company. The Company currently has four directors,
two of whom are disinterested. Under Delaware corporate law, each director owes
a duty of loyalty and care to the Company, which if breached can result in
personal liability for the directors. In addition, the Company may agree to
certain changes in its contractual and other business relationships with AICL,
including pricing, manufacturing allocation, capacity utilization and capacity
expansion, among others, which in the judgment of the Company's management will
result in reduced short-term profitability for the Company in favor of potential
long-term benefits to the Company and AICL. There can be no assurance that the
Company's business, financial condition or results of operations will not be
adversely affected by any such decision. See "-- Liquidity and Capital
Resources" and "Risk Factors -- Dependence on Relationship with AICL; Potential
Conflicts of Interest."

     THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31,
1997
    
 
   
     Net Revenues. The Company's net revenues consist of fees for the packaging
and testing of ICs which are consigned by customers to the Company's or AICL's
factories. The Company's net revenues increased 18.8% to $371.7 million for the
three months ended March 31, 1998, compared to $313.0 million for the same
period in 1997. The growth in revenues was attributable to a significant growth
in unit volumes of semiconductors packaged and tested by the Company. The
proportion of the Company's revenues derived from traditional leadframe products
declined in the first quarter of 1998 as compared to the corresponding quarter
in 1997 while revenues from laminate products and advanced leadframe products
increased during this
    
 
                                       38

period. Because the Company's advanced leadframe and laminate products tend to
have higher average selling prices than traditional leadframe products, this
change in the mix of products sold during the first three months of 1998 helped
to offset generally declining average selling prices for the Company's products
on an overall basis. Revenues from the Company's wafer fabrication services
accounted for less than 1% of total revenues during the first quarter of 1998.
    
 
   
     Gross Profit. Gross profit increased to $61.7 million, or 16.6% of net
revenues, for the three months ended March 31, 1998 from $25.6 million, or 8.2%
of net revenues, in the three months ended March 31, 1997 due primarily to
improved gross profit at the Company's newest factory, P3, compared with
negative gross profit for this factory in the three months ended March 31, 1997
while P3 was in its start-up phase. In addition, increased unit volumes during
the three months ended March 31, 1998 allowed the Company to improve volume
related margins. As a result of the devaluation of the Philippine peso, the
Company also was able to reduce certain peso denominated costs of its Philippine
factory operations, resulting in lower costs and improved gross margins. The new
Supply Agreement with AICL with respect to packaging and test services, which
went into effect on January 1, 1998, also provided the Company with improved
gross margins on products purchased from AICL during the three months ended
March 31, 1998 compared with the three months ended March 31, 1997.
    
 
   
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased to $28.7 million, or 7.7% of net revenues,
during the three months ended March 31, 1998, compared to $20.6 million or 6.6%
of revenues during the three months ended March 31, 1997, as a result of growth
in the number of employees in the Company's marketing and sales support groups
of approximately 21% during 1997. Such growth has resulted in an overall
increase in personnel-related costs including salaries, benefits and payroll
taxes. The Company also incurred higher costs for office rental, depreciation
and other occupancy-related expenses in the first three months of 1998 as
compared to the first three months of 1997. The Company does not expect the
level of growth to continue in 1998.
    
 
   
     Research and Development Expenses. Research and development expenses
increased 38.5% to $2.1 million during the three months ended March 31, 1998,
compared to $1.5 million for the same period in 1997. The increase was primarily
due to increased expenditures by the Company resulting from increased headcount
and corresponding payroll-related costs.
    
 
   
     Other (Income) Expense. Other expense increased during the three months
ended March 31, 1998 to $16.4 million from $8.2 million for the same period in
1997. The increase of $8.2 million was primarily attributable to an increase in
foreign exchange losses, a $1.5 million increase in interest expense and a $2.5
million increase in other expenses, net. Foreign exchange gains and losses
resulted from the change in the value of the Philippine peso relative to the
U.S. dollar which during the three months ended March 31, 1998 resulted in a
$2.7 million dollar foreign exchange loss consisting of realized and unrealized
losses. By comparison, changes in the value of the Philippine peso relative to
the U.S. dollar resulted in a foreign currency gain of $1.5 million for the
three months ended March 31, 1997. Interest expense, net for the first quarter
of 1998 increased $1.5 million compared to the corresponding period in 1997 due
to increased debt balances over the prior year. Other expense, net increased by
$2.5 million for the three months ended March 31, 1998 compared to the same
period in 1997 due primarily to financing costs associated with the accounts
receivable sale agreement entered into by the Company in July 1997 as well as
one-time bank charges incurred during the three months ended March 31, 1998.
    
 
   
     Income Taxes. The Company's effective tax rate (after giving effect to the
pro forma adjustment for income taxes) for the three months ended March 31, 1998
was 29% as compared to 1.3% for the same period in 1997. The low effective tax
rate in 1997 was attributable to losses at the Company's subsidiary which owns
P3. The Company's subsidiary that owns P3 operates under a tax holiday from
Philippine income taxes until the end of 2002. To the extent P3 is profitable,
the Company's effective tax rate related to its Philippine operations during the
tax holiday will be less than the Philippine statutory rate of 35%.
    
 
   
     Equity in Income (Loss) of AICL. Equity in income (loss) of AICL represents
the Company's ownership interest in AICL. During the fourth quarter of 1997, the
Company wrote this investment down to its realizable value and recorded a $17.3
million loss for 1997 resulting principally from the impairment in value in its
investment in AICL. In February 1998, the Company sold its investment in AICL
for $13.9 million. See Note 6 of Notes to Combined Financial Statements.

<PAGE>   41
 
   
     Minority Interest. Minority interest represents AICL's ownership interest
in the consolidated net income of AAP. Accordingly, the Company recorded a
minority interest expense in its combined financial statements relating to the
minority interest in the net income of AAP. The Company has entered into an
agreement with AICL to purchase AICL's 40% interest in AAP and, as a result, the
Company will own all of the common stock of AAP. See "Prospectus Summary -- The
Initial Public Offering." The acquisition of the minority interest will result
in the elimination of the minority interest liability and in additional
amortization of approximately $2.5 million per year.
    
 
     YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
   
     Net Revenues. Net revenues for 1997 increased 24.3% to $1,455.8 million
from $1,171.0 million for 1996 primarily due to an increase in unit volumes of
semiconductors packaged and tested by the Company, offset in part by declines in
average selling prices for many of the Company's leadframe products. In
addition, the opening of P3, the Company's newest factory, and K4, AICL's newest
factory, in September 1996 enabled the Company to begin to expand sales of BGA
packages in 1997.
    
 
     Gross Profit. Gross profit increased 43.1% to $213.1 million in 1997 from
$148.9 million in 1996, resulting in a gross margin of 14.6% for 1997 as
compared to 12.7% for 1996. Cost of revenues consists principally of packaging
and test service charges from AICL, costs of direct material for both the
Philippine factories and AICL and labor and other costs at the Philippine
factories. Gross margin increased primarily due to improved operating results at
P1 and P2 during the second half of 1997, which more than offset initial
operating losses and start-up costs incurred in connection with P3 during the
first half of 1997. Product mix changes toward more profitable product lines and
decreased labor costs from the devaluation of the Philippine peso were the
primary factors resulting in improved margins at the P1 and P2 factories.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 55.7% to $103.7 million, or 7.1% of net
revenues, in 1997 from $66.6 million, or 5.7% of net revenues, in 1996 primarily
due to increases in personnel in marketing and support to sustain the Company's
growth. The number of employees in the Company's marketing and sales support
groups increased during 1997 by approximately 21% over 1996. Such increase
resulted in an overall increase in personnel-related costs including salaries,
benefits and payroll taxes. The Company also incurred increased costs for office
rental, depreciation and other occupancy-related expenses. The Company does not
expect this level of growth in employees to continue in 1998. In addition to the
increased costs from its marketing and sales support groups, the Company
incurred approximately $8.0 million and $3.6 million in general and
administrative expenses in connection with its P3 operations and wafer
fabrication services group, respectively, during 1997. No similar costs were
incurred in 1996 as these groups represented start-up operations in 1997.
 
     Research and Development Expenses. Research and development expenses
decreased 22.0% to $8.5 million, or 0.6% of net revenues, in 1997, from $10.9
million, or 0.9% of net revenues, in 1996. The decrease in research and
development costs principally reflected the termination in late 1996 of the
Company's efforts to develop its own laminate substrate manufacturing
capability.
 
   
     Other (Income) Expense. Other expense increased 40.5% to $39.8 million in
1997 from $28.4 million in 1996 primarily as a result of increased interest
expense and increased other expenses. Interest expense for 1997 increased to
$38.6 million from $27.7 million in 1996 as the Company significantly increased
its borrowing to finance capacity expansion. See "-- Liquidity and Capital
Resources." Interest expense in each of the periods was offset in part by
interest income of $6.4 million and $5.5 million, respectively. Other expenses
increased primarily due to $2.4 million in costs relating to the Company's trade
receivables securitization transactions. See "-- Liquidity and Capital
Resources" and Note 2 of Notes to Combined Financial Statements.
    
 
   
     Income Taxes. The Company's effective tax rate (after giving effect to the
pro forma adjustment for income taxes) for 1997 was 18% as compared to 25% for
1996. The decrease in the Company's effective tax rate in 1997 compared to 1996
was primarily attributable to income not taxed due to the tax holiday available
to the Company's subsidiary which owns P3 and the foreign exchange effects
described below. The Company recognized deferred tax benefits for unrealized
foreign exchange losses in 1997 which are recognized in the Philippines for tax
reporting purposes and relate to unrecognized net foreign exchange losses on
U.S. dollar
    
 
                                       40
<PAGE>   42
 
denominated monetary assets and liabilities. See Note 10 of Notes to Combined
Financial Statements. These losses are not recognized for financial reporting
purposes as the U.S. dollar is the functional currency. These losses will be
realized for Philippine tax reporting purposes upon settlement of the related
asset or liability. The benefit derived from unrealized foreign exchange losses
was partially offset by an increase in the valuation allowance as the Company
concluded that it was more likely than not that their tax benefits could be
realized in the Philippines within the three year loss carryforward period. The
Company has structured its global operations to take advantage of lower tax
rates in certain countries and tax incentives extended to encourage investment.
The recorded provisions for income taxes are subject to changes upon examination
of the Company's tax returns by tax authorities in the United States, the
Philippines and elsewhere. Changes in the mix of income from the Company's
foreign subsidiaries, expiration of tax holidays and changes in tax laws and
regulations could result in increased effective tax rates for the Company.
 
   
     Equity in Income (Loss) of AICL. In 1997, the Company recognized a loss of
$17.3 million resulting principally from the impairment of value in its
investment in AICL. In February 1998, the Company disposed of its investment in
AICL's common stock. See "Certain Transactions" and Note 6 of Notes to Combined
Financial Statements.
    
 
   
     Minority Interest. Minority interest represents AICL's ownership interest
in the consolidated net income of AAP. During 1997, as a result of a settlement
of an intercompany loan, which otherwise had no effect on the combined pretax
income of the Company, AAP reported a net loss as a separate entity.
Accordingly, the Company recorded a minority interest benefit in its combined
financial statements relating to the minority interest in the net loss.
    
 
     YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     Net Revenues. Net revenues in 1996 increased 25.6% to $1.17 billion from
$932.4 million in 1995. The increase was primarily due to an increase in units
sold together with an increase in sales of newer products, such as advanced
leadframe and laminate packages. This increase in sales of newer products offset
declines in average selling prices for many of the Company's other products.
 
     Gross Profit. Gross profit in 1996 and 1995 was approximately $149 million
representing a decrease in gross margin to 12.7% in 1996 from 16.0% in 1995. The
decrease in gross margin was primarily attributable to increases in cost of
revenues due to $15.5 million in pre-operating and start-up costs associated
with P3, as well as increased packaging and test service charges paid to AICL.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 20.1% to $66.6 million, or 5.7% of net
revenues, in 1996 from $55.5 million, or 6.0% of net revenues, in 1995 as a
result of the addition of personnel and infrastructure to service increases in
customer demand. In addition, the Company continued its investments in new
information systems in order to enhance operating efficiencies and improve
customer service and support.
 
     Research and Development Expenses. Research and development expenses
increased 25.2% to $10.9 million, or 0.9% of net revenues, in 1996 from $8.7
million, or 0.9% of net revenues, in 1995 as a result of increased staffing and
funding for the Company's efforts to develop laminate substrate manufacturing
capabilities, prior to termination of such efforts in late 1996.
 
     Other (Income) Expense. Other expense increased 59.0% to $28.4 million in
1996 from $17.8 million in 1995 primarily as a result of increases in interest
expense, net, offset in part by a decrease in other expense, net. Interest
expense, net in 1996 increased to $22.2 million from $9.8 million in 1995 as the
Company significantly increased its borrowing to finance capacity expansion. See
"-- Liquidity and Capital Resources." As a result of this increase in debt, the
Company's interest expense increased to $27.7 million in 1996 from $17.3 million
in 1995.
 
     Income Taxes. The Company's effective tax rate (after giving effect to the
pro forma provision for income taxes) for 1996 and 1995 was 25%. These rates
were different from the United States statutory rate primarily due to the impact
of lower tax rates, including tax holidays, in certain of the countries in which
the Company's subsidiaries are located. See Note 10 of Notes to Combined
Financial Statements.

QUARTERLY RESULTS
 
   
     The following table sets forth certain unaudited combined financial
information, including as a percentage of net revenues, for the eight fiscal
quarters ended March 31, 1998. The Company disposed of its investment in AICL
common stock in February 1998. Also, the Company has entered into an agreement
with AICL pursuant to which the Company will purchase AICL's 40% interest in
AAP. After the disposition of the Company's interest in AICL there was no other
equity in income (loss) of AICL. Following the Company's acquisition of AICL's
interest in AAP, there will be no minority interest related to AAP.
Consequently, this information is not presented below. The amounts of equity in
income (loss) of AICL and minority interest have historically varied
significantly by quarter depending on the income (loss) of AICL and AAP. See
"Reorganization" and Note 6 of Notes to Combined Financial Statements. The
Company believes that all necessary adjustments, consisting only of normal
recurring adjustments, have been included in the amounts stated below to present
fairly the selected quarterly information when read in conjunction with the
Combined Financial Statements and the Notes thereto included elsewhere herein.
The Company's results of operations have varied and may continue to vary
significantly from quarter to quarter and are not necessarily indicative of the
results of any future period. In addition, in light of the Company's recent
growth, the Company believes that period-to-period comparisons should not be
relied upon as an indication of future performance.

     The Company's revenues, gross profit and operating profit 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 United
States, the Philippines and Korea. Semiconductor companies in the United States
generally reduce their production during the holidays at the end of December
which results in a significant decrease in orders for packaging and testing
services during the first two weeks of January. In addition, the Company
typically closes its factories in the Philippines for holidays in January, and
AICL closes its factories in Korea for holidays in February. As a result of
these factors, the Company's net revenues are significantly reduced during the
months of January and February.
    
 
     Beginning in the third quarter of 1996, intense competition in the
semiconductor industry worldwide led to decreases in the average selling prices
of many of the Company's leadframe packages. These decreases were partially
offset by increases in sales of advanced leadframe and laminate packages, which
carry higher prices and gross margins. In addition, the Company's cost of
revenues as a percentage of revenues increased significantly during the three
quarters ended March 31, 1997 primarily as a result of initial operating losses
and start-up costs associated with P3. Cost of revenues was also affected in the
two quarters ended June 30, 1997, as the Company recognized a $2.2 million
write-off for custom laminate raw materials which were purchased to meet
customer orders which were subsequently cancelled. The combined effect of these
factors was to decrease the levels of profitability in the third and fourth
quarters of 1996 and the first quarter of 1997.
 
     Selling, general and administrative expenses increased during the second,
third and fourth quarters of 1997 primarily due to increased staffing levels at
the Company's marketing and sales support groups, as well as at its P3 factory
and wafer fabrication services group, which resulted in increased
employee-related costs. See "-- Results of Operations -- Year Ended December 31,
1997 Compared to Year Ended December 31, 1996 -- Selling, General and
Administrative Expenses."
 
     Income tax rates in the third quarter of 1997 were lower compared to prior
periods as the Company recognized deferred tax benefits for unrealized foreign
exchange losses during the quarter, which are recognized for Philippine tax
reporting purposes but are not recognized for financial reporting purposes since
the U.S. dollar is the functional currency. Although similar circumstances
during the fourth quarter of 1997 resulted in the recognition of additional
deferred tax assets, their effect on the overall tax rates were mitigated by a
valuation allowance also recorded during the fourth quarter of approximately $22
million. See "-- Results of Operations -- Year End December 31, 1997 Compared to
Year Ended December 31, 1996 -- Income Taxes." As the majority of these tax
assets relate to fluctuations in the value of the Philippine peso, management is
unable to determine the impact to the effective tax rates which may occur as a
result of future exchange rate fluctuations.
 
     The Company's quarterly operating results may vary significantly due to a
variety of factors including, among others, the cyclical nature of both the
semiconductor industry and the markets addressed by end-users of semiconductors,
the short-term nature of its customers' commitments, timing and volume of orders
relative to the Company's production capacity, changes in capacity utilization,
evolutions in the life cycles of customers' products, rescheduling and
cancellation of large orders, rapid erosion of packaging selling prices,
availability of manufacturing capacity, allocation of production capacity
between the Company's facilities and AICL's facilities, fluctuations in
packaging and test service charges paid to AICL, changes in costs, availability
and delivery times of labor, raw materials and components, effectiveness in
managing production processes, fluctuations in manufacturing yields, changes in
product mix, product obsolescence, timing of expenditures in anticipation of
future orders, availability of financing for expansion, changes in interest
expense, the ability to develop and implement new technologies, competitive
factors, changes in effective tax rates, the loss of key personnel or the
shortage of available skilled workers, international political or economic
events, currency and interest rate fluctuations, environmental events, and
intellectual property transactions and disputes. Unfavorable changes in any of
the above factors may adversely affect the Company's business, financial
condition and results of operations. In addition, the Company increases its
level of operating expenses and investment in manufacturing capacity in
anticipation of future growth in revenues. To the extent the Company's revenues
do not grow as anticipated, the Company's financial condition and operating
results may be materially adversely affected. See "Risk Factors -- Fluctuations
in Operating Results; Declines in Average Selling Price."

LIQUIDITY AND CAPITAL RESOURCES
 
   
     At March 31, 1998, the Company had cash and cash equivalents of $42.0
million and a working capital deficit of $75.6 million ($6.3 and $111.3 million,
respectively, on a pro forma basis, after giving effect to the termination of
AEI's S Corporation status and the distribution of undistributed earnings
through March 31, 1998). The Company's working capital deficit resulted
primarily from the significant amount of its short-term debt, primarily incurred
in connection with the expansion of its Philippine operations.
    
 
   
     The Company used the net proceeds received from the Initial Public Offering
primarily to repay an aggregate of approximately $240 million of debt, including
the Non-Compliant Loans and $86 million of amounts due to AUSA. In addition, the
Company will use such net proceeds to repay $65 million of short-term loans and
$8 million of term loans and will use $34 million of such net proceeds to
repurchase AICL's 40% interest in AAP. See "Prospectus Summary -- The Initial
Public Offering." Following the application of the estimated net proceeds of the
Initial Public Offering to the Company together with repayments of debt prior to
the Initial Public Offering, the Company will have $54 million of short-term
borrowing and current portion of long-term debt, $244 million of long-term debt
and no amounts then due to AUSA. In addition, the remaining $213 million of such
net proceeds will be available for capital expenditures and working capital.
    
 
   
     The Company has been investing significant amounts of capital to increase
its packaging and test services capacity, including the construction of P3, the
addition of capacity in the Company's other Philippine facilities and the
construction of a new manufacturing facility in the United States. Advanced
packaging processes are being developed at the U.S. facility and full scale
operations are expected to begin in 1999. In 1995, 1996, 1997 and the three
months ended March 31, 1998, the Company made capital expenditures of $123.6
million, $185.1 million, $179.0 million and $33.7 million, respectively. Because
the Company and AICL have added a significant amount of packaging and test
capacity in recent years, the Company intends to decrease its level of capital
expenditures in 1998. The Company currently intends to spend approximately $60
million in capital expenditures in 1998, including for the new factory in the
U.S. and moderate capacity expansion at the Company's existing facilities in the
Philippines to meet expected demand. The Company believes that expenditure
levels could increase substantially in 1999 to provide the Company with adequate
capacity.
    
 
   
     The Company believes that its existing cash balances, cash flow from
operations, available equipment lease financing, bank borrowings and financing
obtained through AUSA will be sufficient to meet its anticipated cash
requirements including working capital and capital expenditures, for at least
the next 12 months. There can be no assurance, however, that lower than expected
revenues, increased expenses, increased costs associated with the purchase or
maintenance of capital equipment, decisions to increase planned capacity or
other events will not cause the Company to seek more capital, or to seek capital
sooner than currently expected. The timing and amount of the Company's actual
capital requirements cannot be precisely determined and will depend on a number
of factors, including demand for the Company's services, availability of capital
equipment, fluctuations in foreign currency exchange rates, changes in
semiconductor industry conditions and competitive factors. There can be no
assurance that such additional financing will be available when needed or, if
available, will be available on satisfactory terms. Failure to obtain any such
financing could have a material adverse effect on the Company. In addition, if
the Company obtains such financing by selling equity securities of the Company,
the Company's stockholders may experience significant dilution.
    
 
   
     The Company historically has met a significant portion of its cash
requirements for working capital and capital expenditures from a combination of
cash from operating activities, short-term and long-term bank loans and
financing obtained for the benefit of the Company by AUSA, a wholly-owned
financing subsidiary of AICL, as well as financing from a trade receivables
securitization agreement. Cash provided by operating activities in 1995, 1996,
1997 and the three months ended March 31, 1998 was $53.3 million, $8.6 million,
$250.1 million and $87.0 million, respectively. Cash provided (used) by
financing activities was $71.2 million, $148.0 million, $(16.0) million and
$(102.5) million for 1995, 1996, 1997 and the three months ended March 31, 1998,
respectively.
    
 
   
     At March 31, 1998, the Company's debt consisted of $120.2 million of
borrowings classified as current liabilities, $197.9 million of long-term debt
and capital lease obligations and $88.3 million of amounts due to
    
                                       44
<PAGE>   46
 
   
AUSA. As of March 31, 1998, the Company had extended guarantees in respect of
bank debt of affiliates in the amount of $5.0 million and in respect of vendor
obligations of an affiliate in the amount of $5.7 million, which amount may vary
over time. At March 31, 1998, the Company had $172.2 million in borrowing
facilities with a number of domestic and foreign banks, of which $23.3 million
remained unused. Certain of the agreements with such banks require compliance
with certain financial covenants and restrictions, and are collateralized by
assets of the Company. These facilities are typically revolving lines of credit
and working capital facilities for one-year renewable periods and generally bear
interest at rates ranging from 8.5% to 21%. Long-term debt and capital lease
obligations outstanding at March 31, 1998 have various expiration dates through
April 2004, and accrue interest at rates ranging from 6.7% to 12.5%. See Note 11
of Notes to Combined Financial Statements.
    
 
   
     The Company has met a significant portion of its financing needs through
financing arrangements obtained by AUSA, AICL's wholly-owned financing
subsidiary. A majority of the amount which was due to AUSA represented
outstanding amounts under financing obtained by AUSA for the benefit of the
Company, with the balance representing payables to AUSA for packaging and
service charges paid to AICL. Based on guarantees provided by AICL, AUSA obtains
for the benefit of the Company a continuous series of short-term financing
arrangements which generally are less than six months in duration, and typically
are less than two months in duration. Because of the short term nature of these
loans, the flows of cash to and from AUSA under this arrangement have been
significant. At March 31, 1998, the Company had utilized $88.3 million of the
approximately $108 million of credit facilities available to the Company through
AUSA. These credit facilities are with U.S. branches of a number of banks
located in Korea and have interest rates ranging from approximately 10.05% to
prime plus 8.5% (17% at March 31, 1998). Because of the recent deterioration of
the Korean economy, Korean banks have begun to raise interest rates applicable
to their lending. See "Risk Factors -- Dependence on International Operations
and Sales; Concentration of Operations in the Philippines and Korea -- Korea."
As its credit lines have been renewed, AUSA has experienced a significant
increase in interest rates, and there can be no assurance that such increases
will not continue. The Company reimburses AUSA for certain of the interest
charges incurred by AUSA under these credit facilities. As an overseas
subsidiary of AICL, AUSA was formed with the approval of the Bank of Korea. If
the Bank of Korea were to withdraw such approval, or if AUSA otherwise ceased
operations for any reason, the Company and AICL would be required to meet their
financing needs through alternative arrangements. Although the Company believes
that alternative financing arrangements will be available in the future, there
can be no assurance that the Company or AICL will be able to obtain alternative
financing on acceptable terms or at all. AUSA has received commitments from its
banks indicating that they intend to renew the facilities when they expire
through at least April 1, 1999. AUSA has extended similar terms to the Company
with respect to amounts due to AUSA by the Company. Accordingly, amounts due to
AUSA are classified as non-current liabilities on the Company's balance sheet at
March 31, 1998. See Notes 2 and 6 of Notes to Combined Financial Statements.
    
 
   
     At March 31, 1998, all of AUSA's debt of $318 million, the Non-Compliant
Loans of $154 million and the Company's obligations under the Receivables Sale
(as defined below) were guaranteed by AICL. AICL currently has a significant
amount of debt relative to its equity and is contingently liable under
guarantees in respect of debt of its subsidiaries and affiliates, including
AUSA. As of December 31, 1997, AICL and its consolidated subsidiaries had
guarantees outstanding in respect of debt of its non-consolidated subsidiaries
and affiliates in the Anam Group in the aggregate amount of approximately W857
billion, including the guarantees of the Company's loans. As a result of its
relationship with AICL, the Company's business, financial condition and
operating results are significantly dependent on AICL. There can be no assurance
that AUSA will be able to obtain additional guarantees, if necessary, from AICL.
In addition, a deterioration in AICL's financial condition could trigger
defaults under AICL's guarantees, causing acceleration of such loans. See
"-- Overview -- Relationship with AICL," "Risk Factors -- Dependence on
Relationship with AICL; Potential Conflicts of Interest" and "Relationship with
AICL"
    
 
     In July 1997, the Company entered into a trade receivables securitization
agreement with a commercial financial institution. Under the terms of the
agreement, the financial institution has committed to purchase, with limited
recourse, all right, title and interest in eligible receivables, as defined in
the agreement, up to $100 million (the "Receivables Sale"). Funds received
pursuant to the agreement reflect a discount of
 
                                       45
<PAGE>   47
 
LIBOR plus 0.375% from accounts receivable sold. The Company applied
approximately $83.4 million of the initial Receivables Sale proceeds together
with approximately $17 million of working capital to reduce the Company's
indebtedness to AUSA, which amounts were advanced by AUSA to entities controlled
by members of James Kim's family. See Note 2 of Notes to Combined Financial
Statements.
 
   
     Prior to the consummation of the Reorganization, AEI was treated for U.S.
federal and certain state tax purposes as an S Corporation under the Internal
Revenue Code of 1986 and comparable state tax laws. As a result, AEI did not
recognize U.S. federal corporate income taxes. Instead, up until the Termination
Date, Mr. and Mrs. Kim and the Kim Family Trusts had been obligated to pay U.S.
federal and certain state income taxes on their allocable portion of the income
of AEI. The Company, Mr. and Mrs. Kim and the Kim Family Trusts have entered
into tax indemnification agreements providing that the Company will be
indemnified by such stockholders, with respect to their proportionate share of
any U.S. federal or state corporate income taxes attributable to the failure of
AEI to qualify as an S Corporation for any period or in any jurisdiction for
which S Corporation status was claimed through the Termination Date. The tax
indemnification agreements also provide that under certain circumstances the
Company will indemnify Mr. and Mrs. Kim and the Kim Family Trusts if such
stockholders are required to pay additional taxes or other amounts attributable
to taxable years on or before the Termination Date as to which AEI filed or
files tax returns claiming status as an S Corporation. AEI has made various
distributions to Mr. and Mrs. Kim and the Kim Family Trusts which have enabled
them to pay their income taxes on their allocable portions of the income of AEI.
Such distributions totaled approximately $19.8 million, $13.0 million and $5.0
million in 1995, 1996 and 1997, respectively. No distributions were made to such
stockholders in the first three months of 1998. The Company declared additional
distributions to such stockholders immediately prior to the consummation of the
Reorganization in an amount equal to AEI's and Amkor Technology, Inc.'s
cumulative net income in all periods prior to the Termination Date less the
aggregate amount of distributions previously made to such stockholders. These
final distributions are intended to provide such stockholders with the balance
of AEI's and Amkor Technology, Inc.'s net income for which they have already
recognized taxable income. Through March 31, 1998, the amount of such
undistributed net income was $35.7 million. Subsequent to March 31, 1998
aggregate distributions of $33.1 million were made to such stockholders. See
"Reorganization" and Notes 1, 10 and 17 of Notes to Combined Financial
Statements.
    
 
FOREIGN CURRENCY TRANSLATION GAINS AND LOSSES
 
     The Company's subsidiaries in the Philippines maintain their accounting
records in U.S. dollars. This is due to the fact that all sales, the majority of
all bank debt and all significant material and fixed asset purchases of such
subsidiaries are denominated in U.S. dollars. As a result, the Philippine
subsidiaries' exposure to changes in the Philippine peso/U.S. dollar exchange
rate relates primarily to certain receivables and advances and other assets
offset by payroll, pension and local liabilities. To minimize its foreign
exchange risk, the Company selectively hedges its net foreign currency exposure
through short-term (generally not more than 30 to 60 days) forward exchange
contracts. To date, the Company's hedging activity has been immaterial.

     The following discussion contains forward-looking statements within the
meaning of the U.S. federal securities laws, including statements regarding the
anticipated growth in the market for the Company's products, the Company's
anticipated capital expenditures and financing needs, the Company's expected
capacity utilization rates, the belief of the Company as to its future operating
performance and other statements that are not historical facts. Because such

INDUSTRY BACKGROUND
 
  Manufacturing Process
 
     The production of a semiconductor is a complex process that requires
increasingly sophisticated engineering and manufacturing expertise. The
production process can be broadly divided into three primary stages: (i) wafer
fabrication, (ii) assembly of die into finished devices (referred to as
"packaging") and (iii) testing of finished devices and other back-end processes.

                             [ORGANIZATIONAL CHART]
 
     The wafer fabrication process begins with the generation of a mask that
defines the circuit patterns for the transistors and interconnect layers that
will be formed on the raw silicon wafer. The transistors and other circuit
elements are formed by repeating a series of process steps wherein a
photosensitive material is first deposited on the wafer, the material is exposed
to light through the mask in a photolithography process, and finally, the
unwanted material is etched away, leaving only the desired circuit pattern on
the wafer. By stacking up the various patterns, the individual elements of the
semiconductor are defined. The final step in the wafer fabrication process is to
electrically test each individual chip in a wafer probe process in order to
identify the good chip for packaging.
 
     The fabricated wafers are then transferred to packaging facilities.
Semiconductor packaging serves to protect the chip, facilitate integration into
electronic systems, and enable the dissipation of heat from the devices. In the
packaging process, the wafer is diced into its individual die which are then
separated from the wafer and attached to a substrate via an epoxy adhesive.
Leads on the substrate are then connected by extremely fine gold wires to the
input/output ("I/O") terminals on the chips through the use of automated
machines known as "wire bonders". Each die is then encapsulated in a plastic
molding compound, thus forming the package, which then goes through several
additional finishing steps to prepare it for testing.
 
     Following packaging, each packaged device is then tested utilizing a
sophisticated test platform and program which tests the many different operating
specifications of the IC, including functionality, voltage, current and timing.
The completed devices are either shipped back to the customer or shipped
directly to their final destination.
 
  Trends Toward Outsourcing
 
     Historically, semiconductor companies manufactured semiconductors primarily
in their own factories. Independent packagers of semiconductors were used solely
to handle the overflow volume requirements of semiconductor companies.
Outsourcing of final testing and wafer fabrication was virtually non-existent in
the
 
                                       48
<PAGE>   50
 
early days of the industry. Over the past fifteen years, however, the need for
independent semiconductor packaging and test services has grown dramatically for
several reasons.
 
     First, semiconductor companies are facing ever-increasing demands for
miniaturization, higher lead counts and improved thermal and electrical
performance in IC packages. As a result of this trend, semiconductor packaging
is now viewed as an enabling technology requiring sophisticated expertise and
technological innovation. Independent providers of packaging and test services
have developed substantial expertise in packaging and test technology and new
package innovation. Semiconductor companies, having found it difficult to keep
pace using their internal resources, have come to rely increasingly on the
independent packaging and test services providers as a key source for new
technology development and innovation.
 
     Second, semiconductor companies are increasingly seeking to shorten their
time to market for new products. Having the right packaging technology and
capacity in place is a critical factor in reducing time to market. As packaging
solutions are identified for a specific product, semiconductor companies
frequently do not have the equipment or expertise to implement such solutions in
the volumes required, nor sufficient time to develop these capabilities before
introducing a new product into the market. For this reason, semiconductor
companies are increasingly leveraging the resources and capabilities of
independent packaging and test companies to deliver their new products to market
more quickly.
 
     Third, the packaging and testing of ICs has evolved into an increasingly
complex process that requires substantial investment in specialized equipment
and facilities. For example, the investment in facilities and equipment
necessary for a processing line capable of packaging 100 million ball grid array
("BGA") packages per year can be as much as $200 million. As a result of the
substantial cost of this manufacturing equipment, the equipment must be utilized
at a high capacity level for an extended period of time in order to be cost
effective. With semiconductor companies facing increasingly shorter product life
cycles, faster new product introductions and the need to continuously update or
replace packaging equipment to accommodate new products, it has become
increasingly difficult for semiconductor companies to sustain such high levels
of capacity utilization. Independent providers of packaging and test services,
on the other hand, can use existing equipment at high utilization levels over a
longer period of time for a broad range of customers, effectively extending the
life of the equipment.
 
     Fourth, as the cost to build a new wafer fabrication facility has increased
to over $1 billion, semiconductor companies have been forced to concentrate
their capital resources on core wafer manufacturing activities. As a result,
semiconductor companies are increasingly seeking to use independent packaging
and test providers who have the ability to invest the capital to develop new
packaging and test capacity. The Company believes that as the cost to construct
new wafer fabrication facilities continues to increase, semiconductor
manufacturers will increasingly seek to outsource packaging and test services.
 
     Fifth, there has been a recent growth of "fabless" semiconductor companies
whose core competency and focus is entirely on the semiconductor design process.
According to industry estimates, sales by fabless semiconductor companies have
grown from $3.2 billion in 1993 to $6.8 billion in 1996, representing 3.7% and
4.8%, respectively, of the worldwide market for semiconductors. The significant
growth in the number of fabless semiconductor companies has been driven in large
part by the ability of such companies to effectively outsource virtually every
significant step of the semiconductor manufacturing process. This development
has allowed fabless semiconductor companies to introduce new semiconductors very
quickly without committing significant amounts of capital and other resources.
The Company believes that increases in the number of fabless semiconductor
companies will continue to be a significant driver of growth in the independent
semiconductor manufacturing industry.
 
     These trends, combined with the growth in the number of ICs being produced
and sold, are driving increasing demand for independent packaging and test
services. According to industry estimates, independent packaging revenues are
expected to grow at a compound annual rate of approximately 16% over a period of
five years from $5.6 billion in 1997 to $11.6 billion in 2002. Today, nearly all
of the world's major semiconductor companies use independent packaging and test
service providers for at least a portion, if not all, of their packaging and
test needs.
 
                                       49
<PAGE>   51
 
     Many of the same forces that have driven the growth of independent
packaging and test have also been driving increasing demand for independent
wafer fabrication services. Moreover, because the cost of new wafer fabrication
facilities has been rising steadily, many semiconductor companies are seeking to
leverage their capital resources by outsourcing some or all of their wafer
fabrication needs. This is particularly true for newer, smaller geometry
technologies that are necessary for producing the newest, leading edge ICs,
because they cannot be produced in many semiconductor companies' existing wafer
fabrication facilities. As the demand for ICs with smaller geometries increases,
the Company believes semiconductor companies will increasingly utilize
independent wafer manufacturers.
 
  The Need for Turnkey Solutions
 
     The growing demand for independent wafer fabrication, packaging, and test
services has generally been served by separate wafer fabrication, packaging or
test companies. This creates inefficiencies for semiconductor companies which
must manage the delays, complex logistics and uncertainty inherent in utilizing
a different service provider for each step of the semiconductor manufacturing
process. Only a very few, if any, independent service providers have the
capability of providing a combination of wafer fabrication, packaging and test
services.

     Traditional Leadframe Products. Traditional leadframe products are the most
widely recognized package types and are characterized by a chip encapsulated in
a plastic mold compound with metal leads surrounding the perimeter. This package
type has evolved from packages designed to be plugged into the circuit board by
inserting the leads into holes on the circuit board to the more modern
surface-mount design, in which the leads are soldered to the surface of the
circuit board. Specific package customization and evolutionary improvements are
continually being engineered to enable improved electrical performance and
multi-chip capability, as well as smaller printed circuit board footprints. The
Company offers a wide range of lead counts and body sizes within this product
group to satisfy customer die size variations. In addition, the Company offers
power versions of the SOP, PLCC, and MQFP package types which are specially
designed to handle today's high power ICs that need with enhanced heat
dissipation characteristics.
 
     Advanced Leadframe Products. The Company's customers are seeking
increasingly thinner packages, which has led the Company to develop newer, more
advanced leadframe products. The Company's advanced leadframe products are
similar in design to its traditional leadframe products. However, the advanced
leadframe products generally are thinner and smaller, have more leads, and have
advanced thermal and electrical characteristics which are necessary for many of
today's more advanced semiconductor applications. The TSOP, TSSOP and SSOP
packages are significantly smaller than the Company's traditional SOIC products,
while the TQFP package is a smaller version of the MQFP package. The Company
also offers power versions of these package types. The Company plans to continue
to develop increasingly smaller versions of these products to keep pace with
continually shrinking die sizes and increasing demands for miniaturization.
 
     Laminate Products. The laminate product family represents the newest and
fastest growth area for the Company and consists of products employing the BGA
format which utilize a laminate (plastic or tape) substrate rather than a
leadframe substrate. BGA technology was first introduced in the industry as a
solution to problems associated with the increasingly high lead counts required
for advanced semiconductors. As the number of leads surrounding the IC
increased, packagers attempted to maintain the size of the package by increasing
the proximity of the leads to one another. As a result, however, these high lead
count packages experienced significant electrical shorting problems and required
the development of increasingly sophisticated and expensive techniques for
producing circuit boards to accommodate the density of the leads. The BGA
methodology solved this problem by effectively creating leads on the bottom of
the package in the form of small bumps or balls. These balls can be evenly
distributed across the entire bottom surface of the package, allowing greater
distance between the individual leads. The Company's first product in this
family was the plastic BGA. The Company has subsequently designed additional BGA
type packages which include features that enable low cost, high volume
manufacturing methods as well as higher performance packages. These new laminate
products include: SuperBGA(R), which includes a copper heat-sink for heat
dissipation and is designed for very low profile, high power applications;
ChipArray(TM), which allows the package to be as small as 1.5 mm larger than the
chip itself; and MicroBGA(TM), which is designed to be approximately the same
size as the chip and uses a tape substrate rather than a plastic laminate. The
Company is currently designing newer versions of BGA packages to enable further
significant reductions in package size.
 
  Test and Related Services
 
     The Company also provides its customers with semiconductor test services.
The Company has the capability to test digital logic, analog and mixed signal
products. The combination of the Company's test operations together with AICL's
Korean test operations comprises one of the largest independent test operations
in the world. Providing test services requires a high level of communication and
integration between the Company and its customers. In order to enable
semiconductor companies to improve their time to market and to reduce costs,
there has been an increasing trend to put packaging and test operations in the
same location. The Company has capitalized on this trend by supplying its own
testers or by supplementing customer-supplied testers with handlers and other
related equipment.
 
     Although test services accounted for only 3.5% of the Company's total 1997
revenue and 13% of the total units shipped, the Company expects test services to
grow significantly during the next several years as customers seek to reduce the
time to market for their products by using contractors with test services at the
 
                                       55

packaging site. In addition to final test services, the Company provides a full
range of other related services, such as burn-in test services, "dry pack"
services, "tape and reel" packing, and wafer "probing" or "sorting."

  Wafer Fabrication
 
     The Company recently began offering wafer fabrication services through
AICL's new deep submicron CMOS foundry. This foundry is currently capable of
producing up to 15,000 8" wafers per month. Through a strategic relationship
with TI, the Company and AICL have qualified .25 micron CMOS process technology,
and TI has agreed to provide to AICL .18 micron CMOS process technology during
1998. The Company's right to the supply of wafers from the foundry is subject to
the TI Manufacturing and Purchasing Agreement, pursuant to which TI has agreed
to purchase at least 40% of the capacity of the foundry and under certain
circumstances has the right to purchase 70% of the capacity of the foundry.
Although the Company has received forecasts from TI which indicate that TI will
meet its minimum purchase obligation during the second half of 1998, during the
first quarter of 1998 TI's orders were below such minimum purchase commitment
and it is uncertain whether TI will meet its purchase obligations in the second
quarter due to market conditions and issues encountered by TI in the transition
of its products to .18 micron technology. There can be no assurance that TI will
place orders representing at least 40% of the capacity of this foundry during
this period or in the future. A failure by TI to comply with its minimum
purchase obligations or the cancellation of a significant wafer fabrication
order by TI or any other customer could have a material adverse effect on AICL's
and the Company's business, financial condition and results of operations. See
"Risk Factors -- Risks Associated with New Wafer Fabrication Business" and
" -- Intellectual Property."
 
     The new foundry's capability is targeted to meet the needs of customers for
DSPs, ASICs and other logic devices. As technological capability and the needs
for CMOS designs in this area change, the Company anticipates the need to add
embedded memory and special analog functionality to its core CMOS technology.
The Company plans to continue to focus its semiconductor technology development
efforts to serve the needs of the high performance digital logic market.
 
     With the addition of the wafer fabrication capability, the Company is able
to offer fully integrated turnkey semiconductor manufacturing services to its
customers. This complete turnkey solution will enable the Company to work with
its customers' IC designers to optimize the integration of IC design with wafer
fabrication, package design, and packaging and test processes. The Company
believes this integration will enable customers to improve the cost and
performance of their ICs and achieve faster time to market in terms of both new
product introductions and production lead times.

The Company's five largest customers collectively accounted for approximately
34.1%, 39.2%, 40.1% and 34.9% of the Company's total revenues in 1995, 1996,
1997 and the three months ended March 31, 1998, respectively. The Company
anticipates that this customer concentration will continue at least for the
foreseeable future. See "Risk Factors -- Customer Concentration; Absence of
Backlog."
    
 
MARKETING AND SALES
 
     The Company sells to and supports its customers through an international
network of offices located in close proximity to its largest customers and
concentration of customers, including offices in the United States (Austin,
Texas; Boise, Idaho; Chandler, Arizona; Dallas, Texas; Santa Clara, California
and West Chester, Pennsylvania), France, Singapore, Taiwan, and the Philippines.
A substantial majority of the Company's sales have historically been derived
from U.S.-based customers. See Note 15 of Notes to Combined Financial
Statements. The Company assigns each of its customers a sales and customer
support team consisting of an account manager, a technical program manager, and
one or more customer support representatives. The largest multinational
customers are typically supported from multiple offices. The Company's worldwide
force of account managers, customer service representatives and technical
product managers exceeds 200 personnel. In addition, an extended staff of
product management, process and reliability engineering, marketing and
advertising, information systems, and factory personnel supports the direct
account teams. Together, these direct and extended teams deliver an array of
services to the Company's customers including providing information and expert
advice on packaging solutions and trends, managing the start-up of specific
packaging and test programs, providing a continuous flow of information to the
customers regarding products and programs in process, and researching and
helping to resolve technical and logistical issues.
 
FACILITIES AND MANUFACTURING
 
  Facilities
 
     The Company provides packaging and test services through its factories in
the Philippines as well as its test facility in the U.S. A new packaging factory

through AICL's four factories in Korea, which provide such services to the
Company pursuant to a Supply Agreement. In 1996, 1997 and the three months ended
March 31, 1998, AICL provided packaging and test services which accounted for
approximately 72%, 68% and 67%, respectively, of the Company's revenues. In
addition to providing world-class manufacturing services, these factories
provide purchasing, engineering, and customer service support. The Company
recently began offering wafer fabrication services through AICL's new
state-of-the-art .25 micron wafer foundry in Korea pursuant to a Supply
Agreement. The size, location, and manufacturing services provided by each of
the Company's and AICL's primary facilities is set forth in the table below. See
"Risk Factors -- Dependence on Relationship With AICL; Potential Conflicts of
Interest," "-- Expansion of Manufacturing Capacity; Profitability Affected by

     The Company's operational headquarters is located in Chandler, Arizona
while its administrative headquarters is located in West Chester, Pennsylvania.
In addition to an executive staff, the Chandler, Arizona campus houses sales and
customer service for the southwest region, product management, a technical
design center, planning, marketing and research and development. The West
Chester location houses finance and accounting, legal, personnel administration,
information systems, and serves as a satellite sales office for the Company's
eastern sales region.
 
  Raw Materials and Equipment
 
     The Company's packaging operations depend upon obtaining adequate supplies
of raw materials on a timely basis. The principal raw materials used in the
Company's packaging process are leadframes or laminate substrates, along with
gold wire and molding compound. The Company purchases raw materials based on the
stated demand requirements of its customers and its customers are generally
responsible for any unused materials that result from an overstatement of
demand. The Company works closely with its primary raw material suppliers to
insure the availability and timeliness of raw material supplies. In addition,
the Company negotiates worldwide pricing agreements with its major suppliers to
take advantage of the scale of its operations. The Company is not dependent on
any one supplier for a substantial portion of its raw material requirements.
 
     The Company's packaging operations and expansion plans also depend on
obtaining adequate supplies of manufacturing equipment on a timely basis. To
that end, the Company works closely with its major equipment suppliers to insure
that equipment deliveries are on time and the equipment meets the Company's
stringent performance specifications. In addition, an affiliate of AICL
manufactures semiconductor packaging equip-
 
                                       58
<PAGE>   60
 
ment exclusively for the Company and AICL at locations in close proximity to the
Company's and AICL's packaging facilities in the Philippines and Korea,
respectively. See "Risk Factors -- Dependence on Raw Materials Suppliers and
Subcontractors."
 
  Total Quality Management
 
     The Company believes that total quality management is a vital component of
its manufacturing strategy. To that end, the Company has established a
comprehensive Quality Operating System designed to promote continuous
improvement and maximize manufacturing yields at high volume production while
maintaining the highest quality standards. Each of the Company's and AICL's
factories is ISO9002 and QS-9000 certified. ISO9002 is a worldwide manufacturing
quality certification program administered by an independent standards
organization. QS9000 is similarly an independently administered manufacturing
quality certification used by United States automotive manufacturers. The
Company believes that many of its customers prefer to purchase from suppliers
who are ISO9002 and QS9000 certified.
 
COMPETITION
 
     The independent semiconductor packaging and test industry is very
competitive, being comprised of approximately 50 companies, with about 15 of
those companies having sales of $100 million per year or more. The Company faces
substantial competition from established packaging companies primarily located
in Asia, such as Advanced Semiconductor Engineering, Inc. (Taiwan), ASE Test
Limited (Taiwan and Malaysia), ASAT Ltd. (Hong Kong), Hana Microelectronics
Public Co. Ltd. (Hong Kong and Thailand), Astra International (Indonesia),
Carsem Bhd. (Malaysia), ChipPAC Incorporated (Korea), Siliconware Precision
Industries Co., Ltd. (Taiwan), and Shinko Electric Industries Co., Ltd. (Japan).
Each of these companies has significant manufacturing capacity, financial
resources, research and development operations, marketing and other
capabilities, and have been operating for some time. Such companies have also
established relationships with many large semiconductor companies which are
current or potential customers of the Company. The principal elements of
competition in the independent semiconductor packaging market include time to
market, breadth of package offering, technical competence, design services,
quality, production yields, customer service, and price. The Company believes it
generally competes favorably with respect to these factors. On a larger scale,
the Company also competes with the internal manufacturing capabilities of many
of its largest customers.
 
     The independent wafer fabrication business is also highly competitive. The
Company expects its wafer fabrication services to compete primarily with
independent wafer foundries such as Chartered Semiconductor Manufacturing, Ltd.,
Taiwan Semiconductor Manufacturing Company, Ltd. and United Microelectronics
Corporation, as well as with device manufacturers such as LG Semicon Co., Ltd.,
Hitachi, Ltd., Toshiba Corp. and Winbond Electronics Corporation, which provide
foundry services for other semiconductor companies. Each of these companies has
significant manufacturing capacity, financial resources, research and
development operations, marketing and other capabilities and have been operating
for some time. Many of these companies have also established relationships with
many large semiconductor companies which are current or potential customers of
the Company. The principal elements of competition in the wafer foundry market
include technology, delivery cycle times, price, product performance, quality,
production yield, responsiveness and flexibility, reliability and the ability to
design and incorporate product improvements. See "Risk Factors -- Competition."
 
RESEARCH AND DEVELOPMENT
 
     The Company's research and development efforts are focused on developing
new package designs and process capabilities, and on improving the efficiency
and capabilities of its existing production processes and materials. The Company
believes that technology development is one of the key success factors in the
packaging market and believes that it has a distinct advantage in this area. In
addition to its internal development work, and its co-development work with
AICL, the Company also works closely with its packaging equipment and raw
material suppliers in developing advanced processing capabilities and materials
for use in the Company's production process. Currently, the Company is focusing
on development programs
                                       59
<PAGE>   61
 
that extend the capability and applicability of the BGA packaging format. These
include high performance BGAs for microprocessors and other high-end devices,
and a chip size package for memory. In addition, the Company is aggressively
developing a flip-chip die attach and connect process for its laminate packages
that has the potential to reduce packaging size and cost and improve package
performance significantly. The flip-chip packaging process involves attaching
the die I/O terminals directly to the lead circuits on the substrate without the
use of gold wires. In addition to providing a smaller package size, this process
is expected to result in significant improvements in packaging yields by
eliminating the delicate wire bonds from the package.
 
   
     As of March 31, 1998, the Company employed approximately 95 persons in
research and development activities. In addition, other management and
operational personnel are involved in research and development activities. In
1995, 1996, 1997 and the three months ended March 31, 1998, the Company's
research and development expenses were approximately $8.7 million, $10.9
million, $8.5 million and $2.1 million, respectively. The Company expects to
continue to invest significant resources in research and development.
    
 
INTELLECTUAL PROPERTY
 
     The Company currently holds 24 U.S. patents, five of which are jointly held
with AICL, related to various IC packaging technologies, in addition to other
pending patents. These patents will expire at various dates from 2012 through
2016. With respect to development work undertaken jointly with AICL, the Company
and AICL share intellectual property rights under the terms of the Supply
Agreements between the Company and AICL. The Supply Agreements also provide for
the cross-licensing of intellectual property rights between the Company and
AICL. In addition, the Company enters into agreements with other developers of
packaging technology to license or otherwise obtain certain process or packaging
technologies.
 
     The Company expects to continue to file patent applications when
appropriate to protect its proprietary technologies; however, the Company
believes that its continued success depends primarily on factors such as the
technological skills and innovation of its personnel rather than on its patents.
The process of seeking patent protection can be expensive and time consuming.
There can be no assurance that patents will be issued from pending or future
applications or that, if patents are issued, they will not be challenged,
invalidated or circumvented, or that rights granted thereunder will provide
meaningful protection or other commercial advantage to the Company. Moreover,
there can be no assurance that any patent rights will be upheld in the future or
that the Company will be able to preserve any of its other intellectual property
rights.
 
     Although the Company is not currently a party to any material litigation,
the semiconductor industry is characterized by frequent claims regarding patent
and other intellectual property rights. As is typical in the semiconductor
industry, the Company may receive communications from third parties asserting
patents on certain of the Company's technologies. In the event any third party
were to make a valid claim against the Company or AICL, the Company or AICL
could be required to discontinue the use of certain processes or cease the
manufacture, use, import and sale of infringing products to pay substantial
damages and to develop non-infringing technologies or to acquire licenses to the
alleged infringed technology. The Company's business, financial condition and
results of operations could be materially and adversely affected by such
developments. Litigation, which could result in substantial cost to and
diversion of resources of the Company, may also be necessary to enforce patents
or other intellectual property rights of the Company or to defend the Company
against claimed infringement of the rights of others. The failure to obtain
necessary licenses or the occurrence of litigation relating to patent
infringement or other intellectual property matters could have a material
adverse effect on the Company's business, financial condition and results of
operations. In addition, AICL has obtained intellectual property for wafer
manufacturing primarily from TI. The licenses granted to AICL by TI under the TI
Technology Agreements are very limited. Although TI has granted to AICL a
license under TI's trade secret rights to use TI's technology in connection with
AICL's provision of wafer fabrication services, TI has not granted AICL a
license under its patents, copyrights and mask works to manufacture
semiconductors for third parties. Although TI has agreed that TI will not assert
a claim for patent, copyright or mask work right infringement against AICL or
the Company in connection with AICL's manufacture of semiconductor products for
third parties, TI has reserved the right to bring such infringement claims
against AICL's or the Company's customers with respect to semiconductor products
purchased from AICL or the Company. As a result, AICL's and the Company's
customers could be subject to patent litigation
                                       60
<PAGE>   62
 
by TI and others, and AICL and the Company could in turn be subject to
litigation by such customers and others, in connection with the sale of wafers
produced by AICL. Any such litigation could materially and adversely affect
AICL's ability to continue to manufacture wafers and AICL's and the Company's
business, financial condition and results of operations.
 
ENVIRONMENTAL MATTERS
 
     The semiconductor packaging process involves a significant amount of
chemicals and gases which are subject to extensive governmental regulations. For
example, liquid waste is produced at the stage at which silicon wafers are diced
into chips with the aid of diamond saws and cooled with running water. In
addition, excess materials on leads and moldings are removed from packaged
semiconductors in the trim and form process. The Company has installed equipment
to collect certain solvents used in connection with its manufacturing process
and has contracted with independent waste disposal companies to remove such
hazardous material.
 
     Federal, state and local regulations in the United States, as well as
environmental regulations in Korea and the Philippines, impose various controls
on the storage, handling, discharge and disposal of chemicals used in the
Company's and AICL's manufacturing processes and on the facilities occupied by
the Company and AICL. The Company believes that its activities, as well as those
of AICL, conform to present environmental and land use regulations applicable to
their respective operations and current facilities. Increasing public attention
has, however, been focused on the environmental impact of semiconductor
manufacturing operations and the risk to neighbors of chemical releases from
such operations. There can be no assurance that applicable land use and
environmental regulations will not in the future impose the need for additional
capital equipment or other process requirements upon the Company or AICL or
restrict the Company's or AICL's ability to expand their respective operations.
The adoption of new ordinances or similar measures or any failure by the Company
or AICL to comply with applicable environment and land use regulations or to
restrict the discharge of hazardous substances could subject the Company or AICL
to future liability or cause their respective manufacturing operations to be
curtailed or suspended.
 
EMPLOYEES
 
   
     As of March 31, 1998, the Company had approximately 9,200 full-time
employees, 7,475 of whom were engaged in manufacturing, 1,210 in manufacturing
support, 95 in research and development, 210 in marketing and sales, and 210 in
finance, business management, and administration. The Company's employees are
not represented by any collective bargaining agreement, and the Company has
never experienced a work stoppage. The Company believes that its relations with
its employees are good. See "Risk Factors -- Dependence on Key Personnel and
Availability of Skilled Workforce."

DIRECTOR COMPENSATION
 
     Directors who are also employees or officers of the Company do not receive
compensation for their services as directors. Non-employee directors are
eligible to receive an annual retainer of $15,000 plus per meeting fees of
$1,000 per board meeting and $1,000 per committee meeting attended. Directors
are reimbursed for travel and related expenses incurred by them in attending
board and committee meetings.
 
   
     1998 Director Option Plan. The Company's 1998 Director Option Plan (the
"Director Plan") was adopted by the Board of Directors in January 1998 and was
approved by the Company's stockholders in April 1998. The Director Plan became
effective immediately prior to the Initial Public Offering. 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.
The Director Plan provides for an initial grant of options to purchase 15,000
shares of Common Stock to each new nonemployee director of the Company (an
"Outside Director") upon the later of the effective date of the Director Plan or
the date which such individual first becomes an Outside Director. In addition,
each Outside Director will automatically be granted subsequent options to
purchase 5,000 shares of Common Stock on each date on which such Outside
Director is re-elected by the stockholders of the Company, provided that as of
such date such Outside 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, except that with respect to initial
grants to directors on the effective date of the Director Plan the exercise
price will be equal 94% of the Initial Public Offering price per share of Common
Stock in the Initial Public Offering. The term of each option is ten years. Each
option granted to an Outside Director vests as to 33 1/3% of the optioned stock
one year after the date of grant, and as to an additional 33 1/3% of the
optioned stock on each anniversary of the date of grant, provided that the
optionee continues to serve as an Outside Director on such date so that 100% of
the optioned stock may be exercisable three years after the date of grant. In
the event of the sale of all or substantially all the Company's assets or the
merger of the company with or into another corporation, all outstanding options
under the Director Plan may either be assumed or an equivalent option may be
substituted by the surviving entity. Following such assumption or substitution,
if the director is terminated other than upon a voluntary resignation, such
assumed or substituted options will vest and become exercisable in full. If no
assumption or substitution occurs, each such option will vest and become
exercisable in full. The Director Plan will terminate in January 2008 unless
sooner terminated by the Board of Directors.

STOCK PLANS
 
     1998 Stock Plan. The Company's 1998 Stock Plan (the "1998 Plan") provides
for the grant to employees of incentive stock options within the meaning of
Section 422 of the Internal Revenue Code of 1986 (the "Code"), and for the grant
to employees, directors and consultants of nonstatutory stock options and stock
purchase rights. The 1998 Plan was adopted by the Board of Directors in January
1998 and was approved by the Company's stockholders in April 1998. Unless
terminated sooner, the 1998 Plan will terminate automatically in January 2008.
The maximum aggregate number of shares which may be optioned and sold under the
1998 Plan is 5,000,000, plus an annual increase to be added on each anniversary
date of the adoption of the 1998 Plan equal to the lesser of (i) the number of
shares of Common Stock needed to restore the maximum aggregate number of shares
of Common Stock which may be optioned and sold under the 1998 to 5,000,000, or
(ii) a lesser amount determined by the Board of Directors.
 
     The 1998 Plan may be administered by the Board of Directors or a committee
appointed by the Board of Directors (the "Committee"), which Committee shall, in
the case of options intended to qualify as "performance-based compensation"
within the meaning of Section 162(m) of the Code, consist of two or more
"outside directors" within the meaning of Section 162(m) of the Code. The Board
of Directors or the Committee, as applicable, has the power to determine the
terms of options granted, including the exercise price and the fair market
value, to reduce the exercise price of any option to the then current fair
market price if the fair market value of the Common Stock covered by such option
shall have declined since the date the option was granted, the number of shares
subject to the option or stock purchase right, and the exercisability thereof
and the form of consideration payable upon such exercise. In addition, the Board
of Directors has the
 
                                       64
<PAGE>   66
 
authority to amend, suspend or terminate the 1998 Plan, provided that no such
action may affect any share of Common Stock previously issued and sold or any
option previously granted under the 1998 Plan.
 
   
     Unless determined otherwise by the administrators, options and stock
purchase rights granted under the 1998 Plan are not transferable by the
optionee, and each option and stock purchase right is generally exercisable
during the lifetime of the optionee only by such optionee. Options granted under
the 1998 Plan must generally be exercised within 30 days following termination
of an optionee's status as an employee, director or consultant of the Company,
within twelve months after an optionee's termination by disability, and within
twelve months after an optionee's termination by death, but in no event later
than the expiration of the option. In the case of stock purchase rights, unless
the administrator determines otherwise, a restricted stock purchase agreement
shall grant the Company a repurchase option exercisable upon the voluntary or
involuntary termination of the purchaser's employment with the Company for any
reason (including death or disability). The purchase price for shares
repurchased pursuant to a restricted stock purchase agreement shall be the
original price paid by the purchaser and may be paid by cancellation of any
indebtedness of the purchaser to the Company. The repurchase option shall lapse
at a rate determined by the administrator. The exercise price of all incentive
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. The exercise price of
nonstatutory stock options granted under the 1998 Plan is determined by the
Committee, but with respect to nonstatutory stock options intended to qualify as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the exercise price must be at least equal to the fair market value of the
Common Stock on the date of grant. With respect to any employee who owns stock
possessing more than ten percent of the voting power of all classes of the
Company's, or any parent or subsidiary of the Company's outstanding capital
stock, the exercise price of any incentive stock option granted to such person
must equal at least 110% of the fair market value of the Common Stock on the
date of grant and the term of such incentive stock option must not exceed five
years. The term of all other options granted under the 1998 Plan may not exceed
ten years.
    
 
     The 1998 Plan provides that in the event of a merger of the Company with or
into another corporation, or a sale of substantially all of the Company's
assets, each outstanding option and stock purchase right will be assumed or
substituted for by the successor corporation. In the event the successor
corporation refuses to assume or substitute for the option or stock purchase
right, the optionee shall have the right to exercise all of the optioned stock,
including shares as to which it would not otherwise be exercisable.
 
     1998 Stock Option Plan for French Employees. The 1998 Stock Option Plan for
French Employees (the "French Plan") was approved by the Board of Directors in
April 1998. Unless terminated sooner, the French Plan will continue in existence
for 5 years. The French Plan provides for the granting of options to employees
of Amkor/Anam EuroServices S.A.R.L. and Amkor Wafer Fabrication Services SARL,
the Company's French subsidiaries (the "French Subsidiaries"). A total of
250,000 shares of Common Stock have been reserved for issuance under the French
Plan plus an annual increase to be added on each anniversary date of the
adoption of the French Plan equal to the lesser of (i) the number of shares of
Common Stock needed to restore the maximum aggregate number of shares of Common
Stock which may be optioned and sold under the French Plan to 250,000, or (ii) a
lesser amount determined by the Board of Directors. Options granted under the
French Plan are not transferable by the optionee other than by will or by the
laws of descent and distribution. The exercise price for each option granted
under the French Plan shall be 100% of the fair market value of the shares of
Common Stock on the date the option is granted and the maximum term of the
option must not exceed ten years.
 
     Stock options granted under the French Plan vest over a five year period
with 50% of the shares subject to cash options vesting on the second anniversary
of the vesting commencement date and 1/24 of the remaining shares subject to
each option vesting each month thereafter. Shares subject to the options granted
under the French Plan may not be transferred, assigned or hypothecated in any
manner other than by will or the laws of descent or distribution before the date
which is five years after the date of grant.
 
     The French Plan may be administered by the Board of Directors or a
committee appointed by the Board of Directors (the "Committee"). The Board of
Directors or the Committee, as applicable, has the power to determine the terms
of options granted, including the exercise price and the fair market value the
number of
 
                                       65
<PAGE>   67
 
shares subject to the option and the exercisability thereof and the form of
consideration payable upon such exercise. In addition, the Board of Directors
has the authority to amend, suspend or terminate the French Plan, provided that
no such action may affect any share of Common Stock previously issued and sold
or any option previously granted under the French Plan.
 
     Unless determined otherwise by the administrators, options granted under
the French Plan are not transferable by the optionee, and each option is
generally exercisable during the lifetime of the optionee only by such optionee.
Options granted under the French Plan must generally be exercised within 30 days
following termination of an optionee's status as an employee of either of the
French Subsidiaries, within six months after an optionee's termination by
disability, and within six months after an optionee's termination by death, but
in no event later than the expiration of the option. The term of all options
granted under the French Plan may not exceed ten years.
 
     The French Plan provides that in the event of a merger of the Company with
or into another corporation, or a sale of substantially all of the Company's
assets, each outstanding option will be assumed or substituted for by the
successor corporation. In the event the successor corporation refuses to assume
or substitute for the option, the optionee shall have the right to exercise all
of the optioned stock, including shares as to which it would not otherwise be
exercisable.
 
   
     1998 Employee Stock Purchase Plan. The Company's 1998 Employee Stock
Purchase Plan (the "Purchase Plan") was adopted by the Board of Directors in
January 1998 and was approved by the stockholders in April 1998. The Board of
Directors has not set an effective date for the Purchase Plan. A total of
1,000,000 shares of Common Stock have been made available for sale under the
Purchase Plan and an annual increase is to be added on each anniversary date of
the adoption of the Purchase Plan equal to the lesser of (i) the number of
shares needed to restore the maximum aggregate number of shares available for
sale under the Purchase Plan to 1,000,000, or (ii) a lesser amount determined by
the Board of Directors. The Purchase Plan, which is intended to qualify under
Section 423 of the Code is administered by the Board of Directors or by a
committee appointed by the Board. 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
and for more than five months in any calendar year. The 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 pay day. The
Purchase Plan will be implemented by consecutive six-month offering periods. The
initial offering period and the date of subsequent offering periods under the
Purchase Plan will be determined by the Board of Directors after the effective
date of the Initial Public Offering. Each participant will be granted an option
on the first day of an offering period, and shares of Common Stock will be
automatically purchased on the last date of each purchase period within the
offering period. If the fair market value of the Common Stock on any purchase
date (other than the final purchase date of the offering period) is lower than
such fair market value on the start date of that offering period, then all
participants in that offering period will be automatically withdrawn from such
offering period and re-enrolled in the immediately following offering period.
The purchase price of the Common Stock under the 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. In the event of a
proposed dissolution or liquidation of the Company, the offering periods then in
progress will be shortened by setting a new exercise date that is before the
dissolution or liquidation, and will terminate immediately prior to the
consummation of the proposed action, unless otherwise provided by the Board. In
the event of a proposed sale of all or substantially all of the Company's assets
or the merger of the Company with or into another corporation, each outstanding
option will be assumed or substituted for by the successor corporation. In the
event the successor corporation refuses to assume or substitute for the options,
the offering periods then in progress will be shortened by setting a new
exercise date that is before the sale or merger and the offering periods then in
progress will end on the new exercise date. Each participant will be notified at
least ten business days prior to the new exercise date, and unless such
participant ends his or her participation, the option will be exercised
automatically on the new exercise date. The Purchase Plan will terminate in
January 2008, unless sooner terminated by the Board of Directors.

401(k) PLAN
 
     The Company participates in a tax-qualified employee savings and retirement
plan (the "401(k) Plan") which covers certain of the Company's employees who are
at least 21 years of age. Pursuant to the 401(k) Plan, employees may elect to
reduce their current eligible compensation by up to 13% of eligible compensation
or the statutorily prescribed annual limit, whichever is lower, and have the
amount of such reduction contributed to the 401(k) Plan. After an eligible
employee completes one year of service and has attained age 21, he or she will
become eligible for the Company matching contributions effective as of the
quarterly entry date after meeting these service and age requirements. The
matching contribution amount is a discretionary amount as determined from time
to time by the Company. The 401(k) Plan is intended to qualify under Section 401
of the Internal Revenue Code of 1986, as amended, so that contributions by
employees or by the Company to the 401(k) Plan, and income earned on plan
contributions, are not taxable to employees until withdrawn from the 401(k)
Plan, and so that contributions by the Company, if any, will be deductible by
the Company when made. The trustee under the 401(k) Plan, at the direction of
each participant, invests the assets of the 401(k) Plan in any of a number of
designated investment options.
 
PHILIPPINE PENSION PLANS
 
     The Company adopted a retirement plan for its eligible Philippine employees
and those eligible employees of designated affiliated companies and subsidiaries
of the Company, the Amkor/Anam Pilipinas, Incorporated Employees' Retirement
Benefit Plan (the "Phillipine Plan"), originally effective January 1, 1988, and
most recently amended on January 1, 1997. Eligible employees are employees with
regular and permanent status that have been employed continuously for one (1)
year by a participating company. Currently, the companies participating in the
Phillipine Plan are AMI, AAAP, and Anam Amkor Precision Machine Company
(Phils.), Incorporated. At normal retirement age (age 60), death, or upon total
and permanent disability, a participant will receive a lump sum benefit payment
based on a percentage of his or her final base monthly salary, as determined by
his or her years of credited service. A participant who retires at age 50 with
at least ten (10) years of service will receive a reduced payment based on the
same formula. Company contributions to the Phillipine Plan are held in trust.
The Phillipine Plan is presently underfunded by $3.8 million. The amount by
which the Phillipine Plan is underfunded decreased from $7.2 million at
September 30, 1997 primarily as a result of payments made by the Company as
required under the plan and the effect of the recent devaluation of the
Phillipine peso to the U.S. dollar. See Note 9 of Notes to Combined Financial
Statements.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS
 
     The Company has adopted provisions in its Certificate of Incorporation that
eliminate to the fullest extent permissible under Delaware law the liability of
its directors to the Company for monetary damages. Such limitation of liability
does not affect the availability of equitable remedies such as injunctive relief
or rescission. The Bylaws provide that the Company shall indemnify its directors
and officers, and may indemnify its other employees and agents, to the fullest
extent permitted by Delaware law, including in circumstances in which
indemnification is otherwise discretionary under Delaware law. The Company has
entered into indemnification agreements with its officers and directors
containing provisions which may require the Company, 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), and to
advance their expenses incurred as a result of any proceeding against them as to
which they could be indemnified.
 
     There is no currently pending litigation or proceeding involving a
director, officer, employee or other agent of the Company in which
indemnification would be required or permitted.

                              CERTAIN TRANSACTIONS
 
   
     AICL was founded in 1956 by Mr. H. S. Kim, who currently serves as the
honorary Chairman and a Representative Director of AICL. AICL is a member of the
Anam Group of companies, consisting principally of companies in Korea in the
electronics industries. The management of AICL and the other companies in the
Anam Group are influenced to a significant degree by the family of H. S. Kim,
which, together with the Company, collectively owned approximately 40.7% of the
outstanding common stock of AICL as of December 31, 1997. A significant portion
of the shares owned by the Kim family are leveraged and as a result of this, or
for other reasons, the family's ownership could be substantially reduced. James
Kim, the founder of the Company and currently its Chairman and Chief Executive
Officer, is the eldest son of H. S. Kim. Since January 1992, in addition to his
other responsibilities, James Kim has been serving as acting Chairman of the
Anam Group and a director of AICL. Mr. In-Kil Hwang, the President and a
Representative Director of AICL, is the brother-in-law of James Kim. In
addition, four other members of Mr. Kim's family are on the 13-member Board of
Directors of AICL. In connection with the Reorganization, Mr. James Kim and
members of his family exchanged their interests in the Amkor Companies in return
for shares of Common Stock. James Kim and members of his family beneficially own
approximately 65.8% of the outstanding Common Stock, and Mr. Kim and other
members of his family will continue to exercise significant control over the
Company. The Company and AICL have had a long-standing relationship. In 1996,
1997 and the three months ended March 31, 1998, approximately 72%, 68% and 67%,
respectively, of the Company's revenues were derived from sales of services
performed for the Company by AICL. In addition, substantially all of the
revenues of AICL in 1996, 1997 and the three months ended March 31, 1998 were
derived from services sold by the Company. The Company expects that the
businesses of the Company and AICL will continue to remain highly interdependent
by virtue of their supply relationship, overlaps and family ties between their
respective shareholders and management, financial relationships, coordination of
product and operation plans, joint research and development activities and
shared intellectual property rights. See "Relationship with AICL" and
"Reorganization."
    
 
     The Company has entered into indemnification agreements with its officers
and directors containing provisions which may require the Company, 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), and to
advance to them expenses incurred as a result of any proceeding against them as
to which they could be indemnified.
 
   
     In connection with the Reorganization, the Company has entered into tax
indemnification agreements with Mr. and Mrs. Kim and the Kim Family Trusts
pursuant to which the Company will be indemnified by such stockholders with
respect to their proportionate share of any U.S. federal or state corporate
income taxes attributable to the failure of AEI to qualify as an S Corporation
for any period or in any jurisdiction for which S Corporation status was claimed
through the Termination Date. The tax indemnification agreements also provide
that under certain circumstances the Company will indemnify Mr. and Mrs. Kim and
the Kim Family Trusts if such stockholders are required to pay additional taxes
or other amounts attributable to taxable years on or before the Termination Date
as to which AEI filed or files tax returns claiming status as an S Corporation.
AEI has made various distributions to such stockholders which have enabled them
to pay their income taxes on their allocable portions of the income of AEI. Such
distributions totaled approximately $13.0 million and $5.0 million in 1996 and
1997, respectively. No distributions were made to such stockholders in the first
three months of 1998. The Company declared additional distributions to such
stockholders prior to the consummation of the Reorganization in an amount equal
to AEI's and Amkor Technology, Inc.'s cumulative net income in all periods prior
to the Termination Date less the aggregate amount of distributions previously
made to such stockholders. These final distributions are intended to provide
such stockholders with the balance of AEI's and Amkor Technology, Inc.'s net
income for which they have already recognized taxable income. Through March 31,
1998, the amount of such undistributed net earnings was $35.7 million.
Subsequent to March 31, 1998, aggregate distributors of $33.1 million were made
to such stockholders. See "Reorganization" and Notes 1, 10 and 17 of Notes to
Combined Financial Statements.

     In February 1998 the Company sold its investment in AICL common stock to AK
Investments, Inc. ("AK Investments"), a company owned by Mr. Kim, for $13.9
million, the market value determined by the closing price of AICL shares on the
Korea Stock Exchange on the date of the sale. In exchange for such shares, AK
Investments assumed $13.9 million of the Company's long-term borrowing from
AUSA. See Note 6 of Notes to Combined Financial Statements.
 
   
     Mr. Kim has executed certain guarantees to lenders in connection with
certain debt instruments of the Amkor Companies that remain outstanding. The
total contingent liability under such guarantees equalled approximately $79
million as of March 31, 1998. See Note 11 of Notes to Combined Financial
Statements.
    
 
     The Company and Mr. Kim currently are parties to a loan agreement under
which Mr. Kim may borrow funds from the Company, subject to the Company's
consent. Mr. Kim has recognized compensation in 1996 and 1997 in the amount of
$101,716 and $3,000, respectively of imputed interest for loans under this
agreement. Since the beginning of the 1996 fiscal year, the maximum amount
outstanding under such agreement has been $6.5 million. All amounts due from Mr.
Kim have been repaid in full subsequent to December 31, 1997.
 
     In 1996, Mr. Kim sold his interest in Amkor Anam Test Services, Inc.,
representing half of its outstanding capital stock, to AEI for $910,350. See
Note 14 of Notes to Combined Financial Statements.
 
   
     AK Investments purchased certain securities held by AEI for $49.7 million,
which consideration was paid by assuming from AEI certain non-current payables
from AUSA. Subsequent to the sale of investments to AK Investments, AEI loaned
AK Investments an additional $12.8 million. This loan was repaid in full as of
March 31, 1998. See Notes 6 and 11 of Notes to Combined Financial Statements. AK
Investments repaid such amount in full during March 1998.
    
 
     In 1996, the Kim Family Trusts borrowed $5.3 million at market interest
rates from AEI to purchase the real estate and develop the facilities that
comprise the Company's Chandler, Arizona plant and offices. In 1997, the Kim
Family Trusts, after making improvements, sold the real estate and facilities
back to AEI for $5.7 million which was used to repay the original loan from AEI.
See Note 11 of Notes to Combined Financial Statements.
 
     Members of the Kim family own all the outstanding shares of Forte Systems,
Inc. ("Forte"). The Company and Forte currently are parties to a loan agreement
under which Forte may borrow funds at market interest rates from the Company,
subject to the Company's consent. Since the beginning of the 1996 fiscal year,

     Members of the Kim family own all the outstanding shares of The Electronics
Boutique, Inc. (the "Electronics Boutique"). The Company and the Electronics
Boutique currently are parties to a loan agreement under which the Electronics
Boutique may borrow funds at market rates from the Company, subject to the
Company's consent. Since the beginning of the 1996 fiscal year, the maximum
amount outstanding under such agreement in the ordinary course of business of
the Electronics Boutique's business has been $3.0 million. In addition, in 1996,
the Electronics Boutique borrowed $50 million from AEI in connection with a
contemplated acquisition. However, this acquisition was abandoned by the
Electronics Boutique and the $50 million was repaid to AEI within eleven working
days of the date it was borrowed. Finally, the Company has guaranteed certain
vendor obligations and a line of credit of the Electronics Boutique, which total
approximately $5.7 million and $3.8 million, respectively as of March 31, 1998.
See Note 11 of Notes to Combined Financial Statements.
    
 
     In addition, in each of the last three years, various Electronics Boutique
expenses were paid by the Company on behalf of Electronics Boutique and various
Company expenses were paid by Electronics Boutique on behalf of the Company.
These expenses include insurance premiums, employee medical claims, interest,
rent and other miscellaneous expenses. In 1995, 1996 and 1997, the Company made
net advancements on behalf of Electronics Boutique of $604,000, $128,000 and
$147,000. In 1997, Electronics Boutique repaid to the Company $2.4 million of
current and prior year advancements.

(1) 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 "Exchange Act"), and the information is not necessarily
    indicative of beneficial ownership for any other purpose. Under such rule,
    beneficial ownership includes any share as to which the individual or entity
    has voting power or investment power. Unless otherwise indicated, each
    person or entity has sole voting and investment power with respect to shares
    shown as beneficially owned.
    
 
(2) James J. and Agnes C. Kim are husband and wife. Accordingly, each may be
    deemed to beneficially own shares of Common Stock held in the name of the
    other.
 
   
(3) 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). In addition, the trust agreement for each
    of these trusts encourages the trustees of the trusts to vote the shares of
    Common Stock held by them, in their discretion, in concert with James Kim's
    family. Accordingly, the trusts, together with their respective trustees and
    James J. and Agnes C. Kim, may be considered a "group" under Section 13(d)
    of the Exchange Act. This group may be deemed to have beneficial ownership
    of 73,525,000 shares or 62.4% of the outstanding shares of Common Stock
    after the Initial Public Offering.
    
 
(4) Salomon Smith Barney may, subject to certain limitations, from time to time,
    borrow shares of Common Stock from Mr. and Mrs. Kim to settle short sales of
    Common Stock (or to return Common Stock previously borrowed by Salomon Smith
    Barney to settle such short sales) entered into by Salomon Smith Barney to
    hedge any long position in the Convertible Notes resulting from its
    market-making activities; provided that the total number of shares borrowed
    at any time may not exceed 7,000,000. See "Plan of
 
                                       71

    Distribution." If at any time 7,000,000 shares are borrowed from Mr. and
    Mrs. Kim and sold and not returned, their beneficial ownership of the Common
    Stock would be reduced to 20.2%.
    
 
(5) These three trusts together with the trusts described in note (6) below
    comprise the Kim Family Trusts.
 
(6) Includes 8,200,000 shares held by a trust established for the benefit of
    Susan Y. Kim's children.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
   
     The Company is authorized to issue 500,000,000 shares of Common Stock,
$.001 par value, and 10,000,000 shares of Preferred Stock, $.001 par value. As
of the date of this Prospectus, there are an aggregate of 117,860,000 shares of
Common Stock outstanding, 3,145,900 shares of Common Stock issuable upon
exercise of outstanding options, 3,404,100 shares of Common Stock reserved for
issuance under the Company's 1998 Stock Plan, 1998 Stock Option Plan for French
Employees, 1998 Director Option Plan and 1998 Employee Stock Purchase Plan and
15,333,333 shares of Common Stock reserved for issuance upon conversion of the
Convertible Notes.
    
 
     The following description of the Company's capital stock does not purport
to be complete and is subject to and qualified in its entirety by the
Certificate of Incorporation and the Bylaws, which are included as exhibits to
the Registration Statement of which this Prospectus forms a part, and by the
provisions of applicable Delaware law.
 
     The Certificate of Incorporation and the Bylaws contain certain provisions
that are intended to enhance the likelihood of continuity and stability in the
composition of the Board of Directors and which may have the effect of delaying,
deferring, or preventing a future takeover or change in control of the Company
unless such takeover or change in control is approved by the Board of Directors.
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote per share on all matters
to be voted upon by the stockholders. Holders of Common Stock do not have
cumulative voting rights, and, therefore, holders of a majority of the shares
voting for the election of directors can elect all of the directors. In such
event, the holders of the remaining shares will not be able to elect any
directors. See "Risk Factors -- Benefits of the Initial Public Offering to
Existing Stockholders; Continued Control by Existing Stockholders."
 
     Holders of the Common Stock are entitled to receive such dividends as may
be declared from time to time by the Board of Directors out of funds legally
available therefor, subject to the terms of any existing or future agreements
between the Company and its debtholders. The Company has never declared or paid
cash dividends on its capital stock, expects to retain future earnings, if any,
for use in the operation and expansion of its business, and does not anticipate
paying any cash dividends in the foreseeable future. See "Dividend Policy." In
the event of the liquidation, dissolution or winding up of the Company, the
holders of Common Stock are entitled to share ratably in all assets legally
available for distribution after payment of all debts and other liabilities and
subject to the prior rights of any holders of Preferred Stock then outstanding.
 
PREFERRED STOCK
 
     The Company's Board of Directors is authorized to issue 10,000,000 shares
of Preferred Stock in one or more series and to fix the price, rights,
preferences, privileges and restrictions thereof, including dividend rights,
dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares constituting
a series or the designation of such series, without any further vote or action
by the Company's stockholders. The issuance of Preferred Stock, while providing
desirable flexibility in connection with possible acquisitions and other
corporate purposes, could have the effect of delaying, deferring or making more
difficult a change in control of the Company and may adversely affect the market
price of, and the voting and other rights of, the holders of Common Stock. The
issuance of Preferred Stock with voting and conversion rights may adversely
affect the voting power of the holders of Common Stock, including the loss of
voting control to others. The Company has no current plans to issue any
additional shares of Preferred Stock. See "Risk Factors -- Anti-Takeover Effects
of Delaware Law and Certain Charter Provisions."
 
                                       73
<PAGE>   75
 
EFFECT OF DELAWARE ANTI-TAKEOVER STATUTE
 
   
     The Company is subject to Section 203 of the Delaware General Corporation
Law (the "Anti-Takeover Law"), which regulates corporate acquisitions. The
Anti-Takeover Law prevents certain Delaware corporations, including those whose
securities are listed for trading on the Nasdaq National Market, from engaging,
under certain circumstances in a "business combination" with any "interested
stockholder" for three years following the date that such stockholder became an
interested stockholder. For purposes of the Anti-Takeover Law, a "business
combination" includes, among other things, a merger or consolidation involving
the Company and the interested shareholder and the sale of more than 10% of the
Company's assets. In general, the Anti-Takeover Law defines an "interested
stockholder" as any entity or person beneficially owning 15% or more the
outstanding voting stock of the Company and any entity or person affiliated with
or controlling or controlled by such entity or person. A Delaware corporation
may "opt out" of the Anti-Takeover Law with an express provision in its original
certificate of incorporation or an express provision in its certificate of
incorporation or bylaws resulting from amendments approved by the holders of at
least a majority of the Company's outstanding voting shares. The Company has not
"opted out" of the provisions of the Anti-Takeover Law. See "Risk
Factors -- Anti-Takeover Effects of Delaware Law and Certain Charter
Provisions."
    
 
TRANSFER AGENT
 
     The Transfer Agent and Registrar for the Common Stock is First Chicago
Trust Company of New York Shareholder Services, 525 Washington Boulevard, Jersey
City, NJ 07310; telephone (201) 324-0014.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Prior to the Initial Public Offering, there had been no market for the
Common Stock and there is no assurance that a significant public market for the
Common Stock will be sustained. Sales of substantial amounts of Common Stock in
the public market could adversely affect the market price of the Common Stock
and could impair the Company's future ability to raise capital through the sale
of its equity securities.
    
 
   
     As of the date of this Prospectus, the Company has outstanding 117,860,000
shares of Common Stock. In addition to the 40,250,000 shares of Common Stock
offered pursuant to the Initial Public Offering, there are approximately
15,333,333 shares of Common Stock issuable upon conversion of the Convertible
Notes, all of which will be freely tradeable. In addition, Salomon Smith Barney
may, subject to certain limitations, from time to time, borrow shares of Common
Stock from Mr. and Mrs. Kim to settle short sales of Common Stock (or to return
Common Stock previously borrowed by Salomon Smith Barney to settle such short
sales) entered into by Salomon Smith Barney to hedge any long position in the
Convertible Notes resulting from its market-making activities; provided that the
total number of shares borrowed at any time may not exceed 7,000,000. Salomon
Smith Barney is not under any obligation to engage in any market-making
transactions with respect to the Convertible Notes, and any market-making in the
Convertible Notes actually engaged in by Salomon Smith Barney may cease at any
time. See "Plan of Distribution." The shares of Common Stock borrowed and
returned to Mr. and Mrs. Kim (the "Control Shares") may be resold from time to
time by Mr. and Mrs. Kim subject to certain volume, manner of sale and other
restrictions described below under Rule 144 under the Securities Act. Excluding
all such freely tradeable shares and Control Shares, approximately 70,610,000
additional shares of Common Stock will be outstanding upon the closing of the
Initial Public Offering (excluding 3,145,900 shares issuable upon the exercise
of outstanding options), all of which are "restricted" shares (the "Restricted
Shares") under the Securities Act. Such Restricted Shares may be sold only if
registered under the Securities Act or sold in accordance with an available
exemption from such registration.
    
 
   
     Under Rule 144, a person (or persons whose shares are aggregated in
accordance with the Rule) who has beneficially owned his or her Restricted
Shares for at least one year, including persons who are affiliates of the
Company, will be entitled to sell, within any three month period a number of
Restricted Shares that does not exceed the greater of (i) one percent of the
then outstanding number of shares of Common Stock (1,178,600 shares of Common
Stock immediately after the consummation of the Initial Public Offering) or (ii)
the average weekly trading volume of the shares of Common Stock during the four
calendar weeks preceding each such sale. In addition, sales under Rule 144 are
also subject to certain manner of sale provisions and notice requirements and to
the availability of current public information about the Company. After
Restricted Shares are held for two years, a person who is not an affiliate of
the Company is entitled to sell such shares under Rule 144 without regard to
such volume limitations, or manner of sale, notice or public information
requirements under Rule 144. Sales of Restricted Shares by affiliates will
continue to be subject to such volume limitations, and manner of sale, notice
and public information requirements.
    
 
   
     In connection with the Initial Public Offering, the Company agreed with the
Underwriters not to offer, pledge, sell, contract to sell, or otherwise dispose
of (or enter into any transaction which is designed to, or could be expected to,
result in the disposition (whether by actual disposition or effective economic
disposition due to cash settlement or otherwise) by the Company or any affiliate
of the Company or any person in privity with the Company or any affiliate of the
Company), directly or indirectly, or announce the offering of, any other shares
of Common Stock or any securities or options convertible into, or exchangeable
or exercisable for, shares of Common Stock (other than the Convertible Notes)
for a period of 180 days following April 30, 1998 without the prior written
consent of Salomon Smith Barney, subject to certain limited exceptions. In
addition, each of the Company's officers, directors and stockholders has agreed
with the Underwriters not to offer, sell, contract to sell, pledge or otherwise
dispose of, or file a registration statement with the Securities and Exchange
Commission in respect of, or establish or increase a put equivalent position or
liquidate or decrease a call equivalent position within the meaning of Section
16 of the Exchange Act with respect to, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for shares of Common
Stock, or publicly announce an intention to effect any such transaction, for a
period of 180 days after April 30, 1998
    
 
                                       75
<PAGE>   77
 
other than pursuant to the Securities Loan Agreement or with the prior written
consent of Salomon Smith Barney, subject to certain limited exceptions.
 
     Beginning April 29, 1999, approximately 70,610,000 Restricted Shares
subject to the lock-up agreements will become eligible for sale in the public
market pursuant to Rule 144.
 
     The Company has granted options to purchase 3,145,900 shares of Common
Stock under the 1998 Stock Plan, 1998 Stock Option Plan for French Employees and
the 1998 Director Option Plan. See "Management -- Stock Plans." The Company
intends to file, within 30 days after the date of the commencement of the
Initial Public Offering, a Form S-8 registration statement under the Securities
Act to register shares of Common Stock reserved for issuance under the 1998
Stock Plan, 1998 Director Option Plan and 1998 Employee Stock Purchase Plan, and
shares of Common Stock issuable upon exercise of outstanding options. Shares of
Common Stock issued upon exercise of options after the effective date of the
Form S-8 will be available for sale in the public market, subject to Rule 144
volume limitations applicable to affiliates and to lock-up agreements.
 
                              PLAN OF DISTRIBUTION
 
     Mr. and Mrs. Kim (referred to herein as the "Lender") and Salomon Smith
Barney have entered into a Securities Loan Agreement (the "Securities Loan
Agreement") which provides that, subject to certain restrictions and with the
agreement of the Lender, Salomon Smith Barney may from time to time borrow,
return and reborrow shares of Common Stock from the Lender (the "Borrowed
Securities"); provided, however, that the number of Borrowed Securities at any
time may not exceed 7,000,000 shares, subject to adjustment to provide
antidilution protection. The Securities Loan Agreement is intended to facilitate
market-making activity in the Convertible Notes by Salomon Smith Barney. Salomon
Smith Barney may, subject to certain limitations, from time to time use Borrowed
Securities to settle short sales of Common Stock (or to return Common Stock
previously borrowed by Salomon Smith Barney to settle such short sales) entered
into by Salomon Smith Barney to hedge any long position in the Convertible Notes
resulting from its market-making activities. Such sales will be made on the
Nasdaq National Market or in the over-the-counter market at market prices
prevailing at the time of sale or at prices related to such market prices.
 
     Market conditions will dictate the extent and timing of Salomon Smith
Barney's market-making transactions in the Convertible Notes and the consequent
need to borrow shares of Common Stock. The availability of shares of Common
Stock under the Securities Loan Agreement, if any, at any time is not assured
and any such availability does not assure market-making activity with respect to
the Convertible Notes. Any market-making actually engaged in by Salomon Smith
Barney may cease at any time. The foregoing description of the Securities Loan
Agreement does not purport to be complete and is qualified in its entirety by
reference to such agreement, the form of which is filed as an exhibit to the
Registration Statement of which this Prospectus is a part.
 
   
     The Lender and the Company have agreed to indemnify Salomon Smith Barney
against certain liabilities including liabilities under the Securities Act.
    
 
     In the ordinary course of business, Salomon Smith Barney has engaged in
investment banking transactions with the Company (including as an Underwriter of
the Initial Public Offering), Mr. and Mrs. Kim and their respective affiliates
and may do so in the future.
 
                                 LEGAL MATTERS
 
     The validity of the Common Stock offered hereby will be passed upon for the
Company by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo
Alto, California.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Amkor Technology, Inc. and AK Industries, Inc.:
 
     We have audited the accompanying combined balance sheets of Amkor
Technology, Inc. and AK Industries, Inc. and subsidiaries (see Note 1) as of
December 31, 1996 and 1997, and the related combined statements of income,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits. We did not audit the financial
statements of Anam Industrial Co., Ltd. ("AICL"), the investment in which is
reflected in the accompanying financial statements using the equity method of
accounting. The investment in AICL represents 4% and 2% of total assets at
December 31, 1996 and 1997, respectively, and the equity in its net income
represents 5% of net income in 1995 and the equity in its net loss represents 4%
and 29% of net income before the equity in income (loss) of AICL in 1996 and
1997, respectively. The statements of AICL were audited by other auditors whose
report has been furnished to us and our opinion, insofar as it relates to
amounts included for AICL, is based solely on the report of the other auditors.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, based upon our audit and the report of other audits, the
financial statements referred to above present fairly, in all material respects,
the combined financial position of Amkor Technology, Inc. and AK Industries,
Inc. and subsidiaries as of December 31, 1996 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.
 
   
     The report of the other auditors referred to above indicates that the
financial statements of AICL have been prepared assuming that AICL will continue
as a going concern. The operations of AICL have been significantly affected, and
will continue to be affected for the foreseeable future, by Korea's unstable
economy caused by currency volatility and unstable finance markets in Korea.
AICL has traditionally operated with a significant amount of debt relative to
its equity and has a significant working capital deficit at December 31, 1997.
Because of Korea's unstable economy and AICL's dependence on debt financing,
there are significant uncertainties that may affect AICL's future operations and
its abilities to maintain or refinance certain debt obligations as they mature,
which raise substantial doubt regarding AICL's ability to continue as a going
concern. The ultimate outcome of these uncertainties cannot be determined
presently and AICL's financial statements do not include any adjustments that
might result from these uncertainties. AICL's plans to address these matters are
included in the notes to the AICL financial statements.

             (U.S. DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE DATA)
 
 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Combination
 
     The combined financial statements of Amkor Technology, Inc. ("ATI") and its
subsidiaries and AK Industries, Inc. and its subsidiary ("Amkor" or the
"Company") include the accounts of the following (these companies are referred
to as the "Amkor Companies"):
 
     - Amkor Electronics, Inc. ("AEI"), a U.S. S Corporation and its wholly
       owned subsidiaries Amkor Receivables Corp and Amkor Wafer Fabrication
       Services SARL (a French Limited Company).
 
     - T.L. Limited ("TLL") (a British Cayman Island Corporation) and its
       Philippine subsidiaries, Amkor Anam Advanced Packaging, Inc. ("AAAP")
       (wholly owned) and Amkor/Anam Pilipinas, Inc. ("AAP") (which is currently
       owned 60% by TLL and 40% by Anam Semiconductor Inc. which changed its
       name in 1998 from Anam Industrial Co., Ltd. ("AICL"-- see Notes 11 and
       16) and its wholly-owned subsidiary Automated MicroElectronics, Inc.
       ("AMI");
 
     - C.I.L., Limited ("CIL") (a British Cayman Islands Corporation) and its
       wholly-owned subsidiary Amkor/Anam Euroservices S.A.R.L. ("AAES") (a
       French Corporation);
 
     - Amkor Anam Test Services, Inc. (a U.S. Corporation) (see Note 14); and
 
     - The semiconductor packaging and test business unit of Chamterry
       Enterprises, Ltd. ("Chamterry"). During the third quarter of 1997
       Chamterry transferred its customers to AEI and CIL and ceased operations
       of its semiconductor and test business unit.
 
     - AK Industries, Inc. ("AKI") (a U.S. Corporation) and its wholly-owned
       subsidiary, Amkor-Anam, Inc. (a U.S. Corporation);
 
     All of the Amkor Companies are substantially wholly owned by Mr. and Mrs.
James Kim or entities controlled by members of Mr. James Kim's immediate family
(the "Founding Stockholders"), except for AAP which is 40% owned by AICL and one
third of AEI and all of AKI which are owned by trusts established for the
benefit of other members of Mr. James Kim's family ("Kim Family Trusts"). The
Amkor Companies are an interdependent group of companies involved in the same
business under the direction of common management. ATI was formed in September
1997 to facilitate the Reorganization and consolidate the ownership of the Amkor
Companies. In connection with the Reorganization, AEI was merged into ATI. Amkor
International Holdings ("AIH") a newly formed Cayman Islands holding company
became a wholly owned subsidiary of ATI. AIH holds the following entities: First
Amkor Caymans, Inc. ("FACI"), a newly formed holding company, and its
subsidiaries AAAP and AAP and AAP's subsidiary AMI, TLL and its subsidiary CIL
and CIL's subsidiary AAES. The relative number of shares of common stock issued
by the Company in connection with each of the transactions comprising the
Reorganization was based upon the relative amounts of stockholders' equity at
December 31, 1997. In exchange for their interests in AEI, Mr. and Mrs. James
Kim and the Kim Family Trusts received two-thirds (9,746,760 shares) and
one-third (4,873,380 shares) of the ATI common stock then outstanding,
respectively. ATI then issued 67,989,851 shares of common stock, representing
approximately 82% of its shares immediately after the Reorganization, in
exchange for all of the outstanding shares of AIH and its subsidiaries. Of such
shares, 27,528,234 shares and, 36,376,617 shares were gifted to Mr. and Mrs.
James Kim and the Kim Family Trusts, respectively, such that Mr. and Mrs. James
Kim and the Kim Family Trusts own 45.1% and 49.9%, respectively, of the ATI
common shares outstanding after the Reorganization. Following such transactions
the Founding Stockholders beneficially owned a majority of the outstanding
shares of ATI common stock. In addition, ATI acquired all of the stock of AKI
from the Kim Family Trusts for $3,000. The merger of AEI and ATI, the creation
of AIH and FACI, the issuance of ATI common stock for AIH and the acquisition of
AKI are collectively referred to as the Reorganization.

             (U.S. DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE DATA)
 
     Included within the Amkor Companies following the Reorganization are ATI,
AIH and its subsidiaries and AKI and its subsidiary. All of the subsidiaries are
wholly owned except for 40% of the common stock of AAP which is owned by AICL
(see Note 16), and a small number of shares of each of AAP, AAAP and AMI which
are required to be owned by directors of these companies pursuant to Philippine
law.
 
     Except for the acquisition of the shares of AKI which has been accounted
for as a purchase transaction, the Reorganization described above was treated
similar to a pooling of interests as it represents an exchange of equity
interests among companies under common control. The purchase price for the AKI
stock, which represents the fair value of these shares, approximates the book
value of AKI. The financial statements are presented on a combined basis as a
result of the common ownership and business operations of all of the Amkor
Companies, including AKI. As a result of the acquisition of AKI, AKI became a
wholly owned subsidiary of ATI; accordingly, future financial statements will be
presented for ATI and its subsidiaries on a consolidated basis.
 
     The financial statements reflect the elimination of all significant
intercompany accounts and transactions.
 
     The investments in and the operating results of 20%- to 50%-owned companies
are included in the combined financial statements using the equity method of
accounting.
 
  Basis of Presentation
 
   
     The accompanying financial statements have been prepared on a going concern
basis which contemplates realization of assets and liquidation of liabilities in
the ordinary course of business. At December 31, 1997 the Company was not in
compliance with certain restrictive covenants of its principal long-term debt
agreements and, as a result, amounts due under these agreements were previously
classified as current liabilities in the combined balance sheet. The Company had
not received any notification that the Company's repayment obligations with
respect to these loans had been accelerated as a result of such covenant
violations. However, there was no assurance that the Company could generate
sufficient cash flow from operations or other sources to satisfy these
liabilities should they become due before maturity. Consequently, the report of
the Company's independent public accountants included a paragraph stating that
there was a substantial doubt as to the ability of the Company to continue as a
going concern. As a result of the Initial Public Offering (see Note 16), the
Company used part of the net proceeds to repay these bank loans and the
paragraph discussed above has been removed from the report of the independent
public accountants.
    
 
  Nature of Operations
 
   
     The Company provides semiconductor packaging and test services to
semiconductor and computer manufacturers located in strategic markets throughout
the world. Such services are provided by the Company and by AICL under a
long-standing arrangement. Approximately 79%, 72% and 68% of the Company's
packaging and test revenues in 1995, 1996 and 1997 respectively, relate to the
packaging and test services provided by AICL.
    
 
  Concentrations of Credit Risk
 
     Financial instruments, for which the Company is subject to credit risk,
consist principally of trade receivables. The Company has mitigated this risk by
selling primarily to well established companies, performing ongoing credit
evaluations and making frequent contact with customers.
 
     At December 31, 1996 and 1997, the Company maintained $34,330 and $53,071,
respectively, in deposits at one U.S. financial institution and $1,861 and
$2,548, respectively, in deposits at U.S. banks which exceeded federally insured
limits.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
             (U.S. DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE DATA)
 
     Additionally, at December 31, 1996 and 1997, the Company maintained
deposits and certificates of deposits totaling approximately $14,649 and
$34,622, respectively, at foreign owned banks.
 
  Significant Customers
 
     The Company has a number of major customers in North America, Asia and
Europe. The Company's largest customer, Intel Corporation, accounted for
approximately 13.3%, 23.5% and 23.4% of net revenues in 1995, 1996 and 1997,
respectively. The Company's five largest customers collectively accounted for
34.1%, 39.2% and 40.1% of net revenues in 1995, 1996 and 1997, respectively. The
Company anticipates that significant customer concentration will continue for
the foreseeable future, although the companies which constitute the Company's
largest customers may change.
 
  Risks and Uncertainties
 
   
     The Company's future results of operations involve a number of risks and
uncertainties. Factors that could affect the Company's future operating results
and cause actual results to vary materially from expectations include, but are
not limited to, dependence on the highly cyclical nature of both the
semiconductor and the personal computer industries, competitive pricing and
declines in average selling prices, dependence on the Company's relationship
with AICL (see Note 11), reliance on a small group of principal customers,
timing and volume of orders relative to the Company's production capacity,
availability of manufacturing capacity and fluctuations in manufacturing yields,
availability of financing, competition, dependence on international operations
and sales, dependence on raw material and equipment suppliers, exchange rate
fluctuations, dependence on key personnel, difficulties in managing growth,
enforcement of intellectual property rights, environmental regulations and
fluctuations in quarterly operating results.
    
 
  Foreign Currency Translation
 
     Substantially all of the Company's foreign subsidiaries use the U.S. dollar
as their functional currency. Accordingly, monetary assets and liabilities which
were originally denominated in a foreign currency are translated into U.S.
dollars at month-end exchange rates. Non-monetary items which were originally
denominated in foreign currencies are translated at historical rates. Gains and
losses from such transactions and from transactions denominated in foreign
currencies are included in other (income) expense, net. The cumulative
translation adjustment reflected in stockholders' equity in the combined balance
sheets relates primarily to investments in unconsolidated companies which use
the local currency as the functional currency (see Note 6).
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents.
 
  Accounts Receivable
 
     At December 31, 1997, trade accounts receivable represent the Company's
interest in receivables sold in excess of amounts purchased by banks under an
accounts receivable sale agreement (see Note 2). Of the total net trade accounts
receivable amount at December 31, 1997, $19,905 relates to the trade accounts
receivable of CIL which were not sold under the Agreement.
 
  Inventories
 
     Inventories are stated at the lower of cost or market. Cost is determined
principally by using a moving average method.

     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:
 
<TABLE>

Building and improvements.............................  10 to 30 years
Machinery and equipment...............................    3 to 5 years
Furniture, fixtures, and other equipment..............   3 to 10 years
</TABLE>
 
     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 was $27,381, $58,497 and $81,159 for 1995, 1996
and 1997, respectively.
 
  Other Noncurrent Assets
 
     Other noncurrent assets consist principally of security deposits, deferred
income taxes and the cash surrender value of life insurance policies.
 
  Other Noncurrent Liabilities
 
     Other noncurrent liabilities consist primarily of pension obligations and
noncurrent income taxes payable.
 
  Income Taxes
 
     The Company accounts for income taxes following the provisions of Statement
of Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes,"
which requires the use of the liability method. If it is more likely than not
that some portion or all of a deferred tax asset will not be realized, a
valuation allowance is provided.
 
     The Company reports certain income and expense items for income tax
purposes on a basis different from that reflected in the accompanying combined
financial statements. The principal differences relate to the timing of the
recognition of accrued expenses which are not deductible for federal income tax
purposes until paid, the use of accelerated methods of depreciation for income
tax purposes and unrecognized foreign exchange gains and losses.
 
     AEI 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 does not recognize U.S. federal corporate income taxes. Instead, the
stockholders of AEI are taxed on their proportionate share of AEI's taxable
income. Accordingly, no provision for U.S. federal income taxes was recorded for
AEI. Given the pending Offerings (see Note 16), for informational purposes, the
accompanying combined statements of income include an unaudited pro forma
adjustment to reflect income taxes which would have been recorded if AEI had not
been an S Corporation, based on the tax laws in effect during the respective
periods (see Note 17).
 
   
     Subsequent to March 31, 1998, AEI terminated its S Corporation Status.
Effective May 1, 1998, the profits of AEI will be subject to federal and state
income taxes at the corporate level.
    
 
  Earnings Per Share
 
     The pro forma net income per common share was calculated by dividing the
pro forma net income by the weighted average number of shares outstanding for
the respective periods, adjusted for the effect of the Reorganization (see Note
16).

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
             (U.S. DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE DATA)
 
     In the fourth quarter of 1997, the Company adopted SFAS No. 128, "Earnings
Per Share," which 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. In accordance with the statement, all prior period per share amounts
have been revised to reflect the new presentation. The Company's basic and
diluted per share amounts are the same for all periods presented. There have
been no changes to historical per share amounts.
 
  Revenue Recognition and Risk of Loss
 
     The Company records revenues upon shipment of packaged semiconductors to
its customers. The Company does not take ownership of customer-supplied
semiconductors. Title and risk of loss remains with the customer for these
materials at all times. Risk of loss for Amkor packaging costs passes upon
completion of the packaging process and shipment to the customer. Accordingly,
the cost of the customer-supplied materials is not included in the combined
statements of income.
 
  Research and Development Costs
 
     Research and development costs are charged to expense as incurred.
 
  Use of Estimates in the Preparation of Financial Statements
 
     The preparation of financial statements in conformity with generally
accepted accounting principles ("GAAP") requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Recently Issued Accounting Standards
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income." This statement establishes standards
for reporting and display of income and its components in financial statements.
The Company will be required to adopt this statement in 1998.
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." Under this statement, reporting
standards were established for the way that public business enterprises report
information about operating segments in annual financial statements and selected
information about operating segments in interim financial reports issued to
shareholders. Generally, financial information is required to be reported on the
basis that it is used internally for evaluating segment performance and deciding
how to allocate resources to segments. This statement is effective for financial
statements for periods beginning after December 15, 1997. In the initial year of
application, comparative information for earlier years presented is to be
restated. This statement need not be applied to interim financial statements in
the initial year of its application, but comparative information for interim
periods in the initial year of application is to be reported in financial
statements for interim periods in the second year of application. The Company
will adopt this statement prospectively for the year ended December 31, 1998.
 
   
  Interim Financial Statements
    
 
   
     The financial statements and related disclosures for the three months ended
March 31, 1997 and 1998 are unaudited and, in the opinion of management of the
Company, include all adjustments (consisting only of normal recurring
adjustments) necessary for the fair presentation of the results for the interim
period. The

results of operations for the three months ended March 31, 1998 are not
necessarily indicative of the results to be expected for the full year.
    
 
  Reclassifications
 
     Certain previously reported amounts have been reclassified to conform with
the current presentation.
 
 2. ACCOUNTS RECEIVABLE SALE AGREEMENT
 
     Effective July 7, 1997, the Company entered into an agreement to sell
receivables (the "Agreement") with certain banks (the "Purchasers"). The
transaction qualifies as a sale under the provisions of SFAS No. 125 "Accounting
For Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities." Under the Agreement, the Purchasers have committed to purchase,
with limited recourse, all right, title and interest in selected accounts
receivable of the Company, up to a maximum of $100,000. In connection with the
Agreement, the Company established a wholly owned, bankruptcy remote subsidiary,
Amkor Receivables Corp., to purchase accounts receivable at a discount from the
Company on a continuous basis, subject to certain limitations as described in
the Agreement. Amkor Receivables Corp. simultaneously sells the accounts
receivable at the same discount to the Purchasers. AICL has guaranteed AEI's
obligations under the Agreement (see Note 11). The Agreement is structured as a
three year facility subject to annual renewals based upon the mutual consent of
the Company and purchasers. The first such renewal date is June 18, 1998. The
Company and AICL did not comply with certain financial covenants under the
Agreement as of December 31, 1997. The Purchasers have agreed to waive
compliance with these covenants through January 2, 1999. The Company applied
approximately $83.4 million of the Receivables Sale proceeds together with
approximately $17 million of working capital to reduce the Company's
indebtedness to AUSA which amounts were advanced by AUSA to entities controlled
by members of James Kim's family.
 
     Proceeds from the sale of receivables were $84,400 in 1997. Losses on
receivables sold under the Agreement were approximately $2,414 in 1997 and are
included in other expense, net. As of December 31, 1997, approximately $6,300 is
included in current liabilities for amounts to be refunded to the Purchasers as
a result of a reduction in selected accounts receivable.

     In addition, the Company authorized 10,000,000 shares of $.001 par value
preferred stock, designated as Series A.
 
     Changes in the division equity account reflected in the combined statement
of stockholders' equity represent the net cash flows resulting from the
operations of the Chamterry semiconductor packaging and test business for the
periods indicated. Such cash flows have been presented as distributions or
capital contributions since these amounts were retained in Chamterry
Enterprises, Ltd. for the benefit of the owners.
 
 5. INVENTORIES
 
     Inventories consist of raw materials and purchased components which are
used in the semiconductor packaging process. The Company's inventories are

     The Company had net unamortized investment costs in excess of the
proportionate share of the investee companies' net assets of approximately
$1,284 and $0 at December 31, 1996 and 1997, respectively.
 
     On August 1, 1997, the Company sold its equity investment in Anam
Semiconductor & Technology Co., Ltd. ("Anam S&T") and certain investments and
notes receivable from companies unrelated to the semiconductor packaging and
test business to AK Investments, Inc., an entity owned by James J. Kim, at cost
($49,740) and AK Investments, Inc. assumed $49,740 of the Company's long-term
borrowings from Anam USA, Inc. Management estimates that the fair value of these
investments and notes receivable approximated the carrying value at August 1,
1997. Subsequent to the sale on August 1, 1997 the Company loaned AK

Investments, Inc. $12,800 for the purchase of additional investments. The amount
outstanding on this loan at December 31, 1997 was $4,350.
 
     The Company's investment in AICL is accounted for using the equity method
of accounting. Although the Company does not own in excess of 20% of the
outstanding common stock of AICL, the Company through its common ownership with
the Kim family and entities controlled by the Kim family owns 40.7% of the
outstanding common stock of AICL and may exercise a significant influence over
AICL. Accordingly the Company applies the equity method based on its ownership
interest. A significant portion of the shares owned by the Kim family are
leveraged and as a result of this, or for other reasons, the family's ownership
could be substantially reduced.
 
     In 1997, the Company recognized a loss of $17,291, resulting principally
from the impairment of value of its investment in AICL as well as the current
year equity in income (loss) of AICL. The amount of the loss was determined
based upon the market value of the AICL shares on the Korean Stock Exchange on
February 16, 1998, the date that the Company sold its investment in AICL common
stock to AK Investments, Inc. In exchange for the shares, AK Investments, Inc.
assumed $13,863 of the Company's long-term borrowings from Anam USA, Inc.
 
     The Company is advised that AICL, as a public company in Korea, has
published its most recent consolidated financial statements as of December 31,
1997.
 
     The Korean economy is undergoing changes as evidenced by the agreement
between the Korean government and the International Monetary Fund. Among other
things, this agreement includes a restructuring plan of the banking industry as
a whole which will most likely have a material effect on AICL's operations. The
overall impact of these economic changes on AICL is uncertain at this time.
AICL's independent auditors' report indicates that the financial statements of
AICL have been prepared assuming that AICL will continue as a going concern. The
operations of AICL have been significantly affected, and will continue to be
affected for the foreseeable future, by Korea's unstable economy caused by
currency volatility and unstable finance markets in Korea. AICL has
traditionally operated with a significant amount of debt relative to its equity
and has a significant working capital deficit at December 31, 1997. Because of
Korea's unstable economy and AICL's dependence on debt financing, the report
indicates that there are significant uncertainties that may affect AICL's future
operations and its abilities to maintain or refinance certain debt obligations
as they mature, which raise substantial doubt regarding AICL's ability to
continue as a going concern. The ultimate outcome of these uncertainties cannot
be determined presently and AICL's financial statements do not include any
adjustments that might result from these uncertainties. AICL's plans to address
these matters are included in the notes to the AICL's financial statements.
 
     AICL's financial statements are prepared on the basis of Korean GAAP, which
differs from U.S. GAAP in certain significant respects. The Company's equity in
income (loss) of AICL is based upon the Korean GAAP information noted above and
the Company's estimate of significant U.S. GAAP adjustments. These adjustments
were not significant in 1995 and 1996. In 1997, AICL recognized a W349 billion
loss principally as a result of foreign exchange losses on U.S. dollar
denominated liabilities due to the significant depreciation of the won relative
to the U.S. dollar. For purposes of determining the Company's equity in income
(loss) of AICL under U.S. GAAP, losses on remeasuring U.S. dollar denominated
liabilities are not recognized as the U.S. dollar is the functional currency for
AICL. Such U.S. dollar denominated liabilities were W2,144 billion at December
31, 1997. Also, at December 31, 1997, the carrying value of the investment in
AICL, adjusted for the loss on the 1998 disposition discussed above, is less
than the Company's portion of AICL's net assets after consideration of the
estimated U.S. GAAP adjustments. The most significant such adjustment affecting
net assets is the remeasurement of property, plant and equipment to historical
costs as required as the U.S. dollar is the functional currency.

 7. SHORT-TERM CREDIT FACILITIES
 
     At December 31, 1996 and 1997, short-term borrowings consisted of various
operating lines of credit and working capital facilities maintained by the
Company. These borrowings are secured by receivables, inventories or property.
These facilities, which are typically for one-year renewable terms, generally
bear interest at current market rates appropriate for the country in which the
borrowing is made (ranging from 7.2% to 13.0% at December 31, 1997). For 1996
and 1997, the weighted average interest rate on these borrowings was 7.8% and
8.6%, respectively. Included in cash and cash equivalents is $1,200 of
certificates of deposit pledged as collateral for certain of these lines. The
unused portion of lines of credit total $36,169 at December 31, 1997.

     The Bank loans were obtained to finance the expansion of the Company's
factories in the Philippines. The Company has the option to prepay all or part
of the loans on any interest payment date. These Bank loans are unconditionally
and irrevocably guaranteed by AICL. The Bank loans contain provisions pertaining
to the maintenance of specified debt-to-equity ratios, restrictions with respect
to corporate reorganization, acquisition of capital stock or substantially all
of the assets of any other corporations and advances and dispositions of all or
a substantial portion of the borrower's assets, except in the ordinary course of
business. AAP has not been in compliance with covenants regarding the
maintenance of certain debt-to-equity ratios and advances to affiliates. As a
result of the receipt of the net proceeds from the Initial Public Offering (see
Note 16), amounts due under these agreements and certain other agreements with
cross-default clauses have been classified as non-current liabilities in the
accompanying combined balance sheet.
    
 
     Other bank debt instruments have interest rates based on Singapore
interbank rates and LIBOR plus an annual spread. The loans are secured by assets
of the Company and assets acquired through proceeds from the loans.

 9. EMPLOYEE BENEFIT PLANS
 
  U.S. Pension Plans
 
     AEI has a defined contribution benefit plan covering substantially all U.S.
employees under which AEI matches 75% of the employee's contributions of between
6% and 10% of salary, up to a defined maximum on an annual basis. The pension
expense for this plan was $483, $776 and $959 in 1995, 1996 and 1997,
respectively. The pension plan assets are invested primarily in equity and fixed
income securities.
 
  Philippine Pension Plans
 
     AAAP, AAP and AMI sponsor several defined benefit plans that cover
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 defined benefit plans
are as follows:

     The Company has structured its global operations to take advantage of lower
tax rates in certain countries and tax incentives extended to encourage
investment. AAP had a tax holiday in the Philippines which expired in 1995. AAAP
has a tax holiday in the Philippines which expires at the end of 2002. Foreign
exchange losses recognized for income taxes relate to unrecognized net foreign
exchange losses on U.S. dollar denominated monetary assets and liabilities.
These losses, which are not recognized for financial reporting purposes as the
U.S. dollar is the functional currency (see Note 1), result in deferred tax
assets that will be realized, for Philippine tax reporting purposes, upon
settlement of the related asset or liability. The deferred tax asset related to
these losses increased in 1997 as a result of the dramatic devaluation of the
Philippine peso relative to the U.S. dollar. The Company's ability to utilize
these assets depends on the timing of the settlement of the related assets or
liabilities and the amount of taxable income recognized within the Philippine
statutory carryforward limit of three years. Accordingly, a valuation allowance
has been established in 1997 for a portion of the related deferred tax assets.
 
     The following is a summary of the significant components of the Company's
deferred tax assets and liabilities:

     At December 31, 1996 and 1997 current deferred tax assets of $1,919 and
$13,439, respectively, are included in other current assets and noncurrent
deferred tax assets of $379 and $574, respectively, are included in other assets
in the combined balance sheet. The Company's net deferred tax assets include
amounts which management believes are realizable through future taxable income.
 
     The Company's tax returns have been examined through 1993 in the
Philippines and through 1994 in the U.S. The recorded provision for open years
is subject to changes upon final examination of these tax returns. Changes in
the mix of income from the Company's foreign subsidiaries, expiration of tax
holidays and changes in tax laws or regulations could result in increased
effective tax rates for the Company.
 
     At December 31, 1997, the financial reporting basis of AEI's net assets
were greater than the tax basis of the net assets by approximately $5,200. In
connection with the Initial Public Offering, the Company and the stockholders of
AEI will enter into a Tax Indemnification Agreement providing that the Company
and AEI will be indemnified by such stockholders, with respect to their
proportionate share of any federal or state corporate income taxes attributable
to the failure of AEI to qualify as an S Corporation for any period or in any
jurisdiction for which S Corporation status was claimed through the date AEI
terminates its S Corporation status. The Tax Indemnification Agreement will also
provide that the Company and AEI will indemnify the stockholders if such
stockholders are required to include in income additional amounts attributable
to taxable years on or before the date AEI terminates its S Corporation status
as to which AEI filed or files tax returns claiming status as an S Corporation.
 
11. RELATED-PARTY TRANSACTIONS
 
     At December 31, 1997, the Company owned 8.1% of the outstanding stock of
AICL (see Note 6), and AICL owned 40% of AAP. After the Initial Public Offering
(see Note 16) the Company intends to purchase AICL's interest in AAP for
approximately $34,000. In 1996 and 1997, approximately 72% and 68%,
respectively, of the Company's net revenues (see Note 1) were derived from
services performed for the Company by AICL, a Korean public company in which the
Company and certain of the Company's principal stockholders hold a minority
interest. By the terms of a long-standing agreement, the Company has been
responsible for marketing and selling AICL's semiconductor packaging and test
services, except to customers in Korea and certain customers in Japan to whom
AICL has historically sold such services directly. The Company has worked
closely with AICL in developing new technologies and products. The Company has
recently entered into five-year supply agreements with AICL giving the Company
the first right to market and sell substantially all of AICL's packaging and
test services and the exclusive right to market and sell all of the wafer output
of AICL's new wafer foundry. The Company's business, financial condition and
operating results have been and will continue to be significantly dependent on
the ability of AICL to effectively provide the contracted services on a
cost-efficient and timely basis. The termination of the Company's relationship
with AICL for any reason, or any material adverse change in AICL's business
resulting from underutilization of its capacity, the level of its debt and its
guarantees of affiliate debt, labor disruptions, fluctuations in foreign
exchange rates, changes in governmental policies, economic or political
conditions in Korea or any other change could have a material adverse effect on
the Company's business, financial condition and results of operations.
 
     The Company has obtained a significant portion of its financing from
financing arrangements provided by Anam USA, Inc. ("AUSA"), AICL's wholly-owned
financing subsidiary. A majority of the amount due to AUSA represents
outstanding amounts under financing obtained by AUSA for the benefit of the
Company with the balance representing payables to AUSA for packaging and service
charges paid to AICL. Based on guarantees provided by AICL, AUSA obtains for the
benefit of the Company a continuous series of short-term financing arrangements
which generally are less than six months in duration, and typically are less
than two months in duration. Because of the short-term nature of these loans,
the flows of cash to and from AUSA

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
             (U.S. DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE DATA)
 
under this arrangement are significant. Purchases from AICL through AUSA were
$354,062, $460,282 and $527,858 for 1995, 1996 and 1997, respectively. Charges
from AUSA for interest and bank charges were $4,484, $7,074 and $6,002 for 1995,
1996 and 1997, respectively. Amounts payable to AICL and AUSA were $252,221, and
$156,350 at December 31, 1996 and 1997, respectively.
 
     AICL's ability to continue to provide services to the Company will depend
on AICL's financial condition and performance. AICL currently has a significant
amount of debt relative to its equity, which debt the Company expects will
continue to increase in the foreseeable future. The Company is advised that
AICL, as a public company in Korea, has published its most recent annual
consolidated financial statements as of December 31, 1997. These consolidated
financial statements are prepared on the basis of Korean GAAP, which differs
from U.S. GAAP. U.S. GAAP financial statements are not available (See Note 6).
As of December 31, 1997, AICL, on a consolidated basis, had current liabilities
of approximately W2,124 billion, including approximately W1,721 billion of
short-term borrowings and approximately W121 billion of current maturities of
long-term debt, and had long-term liabilities of approximately W1,710 billion,
including approximately W737 billion of long-term debt and approximately W862
billion of long-term capital lease obligations. As of such date, the total
shareholders' equity of AICL amounted to approximately W77 billion. The
deterioration of the Korean economy in recent months and the resulting liquidity
crisis in Korea have led to sharply higher domestic interest rates and reduced
opportunities for refinancing or refunding maturing debts as financial
institutions in Korea, which are experiencing financial difficulties, are
increasingly looking to limit their lending, particularly to highly leveraged
companies, and to increase their reserves and provisions for non-performing
assets. Therefore, there can be no assurance that AICL will be able to refinance
its existing loans or obtain new loans, or continue to make required interest
and principal payments on such loans or otherwise comply with the terms of its
loan agreements. Any inability of AICL to obtain financing or generate cash flow
from operations sufficient to fund its capital expenditure, debt service and
repayment and other working capital and liquidity requirements could have a
material adverse effect on AICL's ability to continue to provide services and
otherwise fulfill its obligations to the Company.
 
     As of December 31, 1997, AICL and its consolidated subsidiaries were
contingently liable under guarantees in respect of debt of its non-consolidated
subsidiaries and affiliates in the aggregate amount of approximately W857
billion. As of December 31, 1997, such guarantees included those in respect of
all of AUSA's debt totaling $319,200, $176,250 of the Company's debt to banks
and the Company's obligations under a receivables sales arrangement (see Note
2). The Company has met a significant portion of its financing needs through
financing arrangements obtained by AUSA for the benefit of the Company based on
guarantees provided by AICL. There can be no assurance that AUSA will be able to
obtain additional guarantees, if necessary, from AICL. Further, a deterioration
in AICL's financial condition could trigger defaults under AICL's guarantees,
causing acceleration of such loans. In addition, as an overseas subsidiary of
AICL, AUSA was formed with the approval of the Bank of Korea. If the Bank of
Korea were to withdraw such approval, or if AUSA otherwise ceased operations for
any reason, the Company and AICL would be required to meet their financing needs
through alternative arrangements. There can be no assurance that the Company or
AICL will be able to obtain alternative financing on acceptable terms or at all.
In addition, if any relevant subsidiaries or affiliates of AICL were to fail to
make interest or principal payments or otherwise default under their debt
obligations guaranteed by AICL, AICL could be required under its guarantees to
repay such debt, which event could have a material adverse effect on its
financial condition and results of operations.
 
     Anam Engineering and Construction, an affiliate of AICL, built the
packaging facility for AAAP in the Philippines. Payments to Anam Engineering and
Construction were $22,167 and $3,844 in 1996 and 1997, respectively. Anam
Precision Equipment and Anam Instruments manufacture certain equipment used by
the Philippine operations. Payments to Anam Precision Equipment and Anam
Instruments were $6,652 and

             (U.S. DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE DATA)
 
$4,211 in 1996 and 1997, respectively. The Company purchases direct materials
from Anam S&T. Payments to Anam S&T were approximately $16,400, $27,300 and
$26,000 during 1995, 1996 and 1997, respectively.
 
     During 1996, the Company extended guarantees on behalf of an affiliate to
vendors used by this affiliate. Outstanding guarantees as of December 31, 1996
and 1997 were $25,100 and $24,655 respectively. Amounts guaranteed under this
agreement fluctuate due to the cyclical nature of the affiliate's retail
business. Balances guaranteed at December 31 are generally the largest.
 
     The Company has executed a surety and guarantee agreement on behalf of an
affiliate. The Company has unconditionally guaranteed the affiliate's obligation
under a $17,000 line of credit and a $9,000 term loan note. As of December 31,
1997, there was $750 outstanding under the line of credit and $9,000 outstanding
under the term loan note. The Company has also unconditionally guaranteed
another affiliate's obligation under a $4,000 term loan agreement and a $1,000
line of credit. As of December 31, 1997, there was $3,800 outstanding under the
term loan and no amounts outstanding under the line of credit.
 
     A principal stockholder of the Company has extended guarantees on behalf of
the Company in the amount of $87,000 at December 31, 1997. Also in 1997, a
company controlled by this stockholder purchased investments in the amount of
$49,740 (see Note 6).
 
     The Company leases office space in West Chester, PA from certain
stockholders of the Company. The lease expires in 2006. The Company has the
option to extend the lease for an additional 10 years through 2016. On September
11, 1997, the office previously being leased in Chandler, Arizona was purchased
from certain stockholders of the Company. The total purchase price of the
building ($5,710) represents the carrying value to the stockholders. Amounts
paid for these leases in 1996 and 1997 were $1,343 and $1,458, respectively.
 
     At December 31, 1996 and 1997, the Company had advances and notes
receivable from affiliates other than AICL and AUSA of $22,988 and $36,501,
respectively. Realization of these notes is dependent upon the ability of the
affiliates to repay the notes. In management's opinion, these receivables are
recorded at the net realizable value.
 
12. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The estimated fair value of financial instruments has been determined by
the Company 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 the Company could realize in a
current market exchange. Certain of these financial instruments are with major
financial institutions and expose the Company 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 methods and assumptions used to estimate the fair value of significant
classes of financial instruments is set forth below:
 
     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.
 
     Short-term borrowings. Short-term borrowings have variable rates that
reflect currently available terms and conditions for similar borrowings. The
carrying amount of this debt is a reasonable estimate of fair value.
 
     Long-term debt and due to affiliates. Long-term debt and due to affiliates
have variable rates that reflect currently available terms and conditions for
similar debt. The carrying amount of this debt is a reasonable estimate of fair
value.

13. COMMITMENTS AND CONTINGENCIES
 
     The Company is involved in various claims incidental to the conduct of its
business. Based on consultation with legal counsel, management does not believe
that any claims to which the Company is a party will have a material adverse
effect on the Company's financial condition or results of operations.
 
     Future minimum lease payments under operating leases that have initial or
remaining noncancelable lease terms in excess of one year at December 31, 1997,
are:

     Rent expense amounted to $3,692, $5,520 and $6,709 for 1995, 1996 and 1997,
respectively.
 
     The Company has various purchase commitments for materials, supplies and
capital equipment incidental to the ordinary conduct of business. As of December
31, 1997 the Company had commitments for capital equipment of approximately
$27,000. In the aggregate, such commitments are not at prices in excess of
current market.
 
14. ACQUISITION OF AMKOR ANAM TEST SERVICES, INC.
 
     On September 30, 1996, AEI and a principal stockholder each acquired 50% of
the outstanding common stock of Amkor Anam Test Services, Inc. (AATS), formerly
Navell Test Consultants, Inc., a provider of test engineering services for the
semiconductor industry located in San Jose, California, for approximately
$2,860. Subsequent to September 30, 1996, AEI purchased the 50% interest owned
by a principal stockholder at the stockholder's original cost. The acquisition
was accounted for using the purchase method of accounting and the results of
AATS' operations are included in the Company's combined statements of income
effective October 1, 1996. Accordingly, the total purchase price has been
allocated to the combined assets and liabilities based upon their estimated
respective fair values. This acquisition resulted in goodwill of approximately
$2,356, which is being amortized over 20 years.

     Sales between affiliates are priced at customer selling price less material
costs provided by the segment, less a sales commission. Net revenues from
unaffiliated customers for the United States include $109,532, $160,507 and
$208,062 of revenues from unaffiliated foreign customers for 1995, 1996 and
1997, respectively. Identifiable assets are those assets that can be directly
associated with a particular geographic area. Corporate assets are those assets
which are not directly associated with a particular geographic area and consist
primarily of cash and cash equivalents, investments and advances or loans to
another geographic segment.

16. SUBSEQUENT EVENTS
 
   
     Reorganization -- On April 14, 1998, Mr. and Mrs. James Kim and the Kim
Family Trusts exchanged their interests in AEI for 9,746,766 shares and
4,873,383 shares of ATI common stock, respectively. On April 29, 1998, ATI
issued 67,989,851 shares of common stock in exchange for all of the outstanding
shares of AIH and its subsidiaries. Of such shares, 19,328,234 shares,
36,376,617 shares and 8,200,000 shares were gifted to Mr. and Mrs. James Kim,
the Kim Family Trusts and other members of Mr. Kim's immediate family,
respectively. In addition, ATI acquired all of the stock of AKI from the Kim
Family Trusts for $3,000. Except for the acquisition of the shares of AKI which
has been accounted for as a purchase transaction, the Reorganization described
above is treated similar to a pooling of interests as it represents an exchange
of equity interests among companies under common control. The purchase price for
the AKI stock, which represents the fair value of these shares, approximates the
book value of AKI (See Note 1 regarding the basis of presentation and income
taxes).
    
 
   
     Initial Public Offering -- ATI filed an amended registration statement on
April 29, 1998 with the Securities and Exchange Commission. On May 6, 1998, ATI
completed its Initial Public Offering of 30,000,000 shares of its common stock
at a price to the public of $11.00 per share and $180,000 aggregate principal
amount of Convertible Notes ("Initial Public Offering"). Also on May 8, 1998,
ATI sold 5,250,000 additional shares of its common stock and $27,000 additional
principal amounts of Convertible Notes in conjunction with the underwriters'
over-allotment options. The net proceeds were approximately $559,757, after
deducting the underwriter discounts and estimated offering expenses. (See Note
1) The convertible notes 1) are convertible into ATI common stock at $13.50 per
share; 2) are callable in certain circumstances after three years; 3) are
unsecured and subordinate to senior debt; 4) carry a coupon rate of 5 3/4%; and
5) have a maturity of five years. Approximately $227,000 of the proceeds will be
used to reduce short-term and long-term borrowings. Approximately $86,000 of the
proceeds will be used to reduce amounts due to AUSA. In connection with the
Offerings, one existing stockholder sold approximately 5,000,000 of his shares.
    
 
   
     The Company established stock option plans in 1998 pursuant to which
6,550,000 shares of common stock were reserved for future issuance upon the
exercise of stock options granted to employees, consultants and directors. The
options will be issued at fair value and generally will vest over four years.
    
 
     After the Initial Public Offering, the Company intends to purchase AICL's
40% interest in AAP for approximately $34,000. The Company will account for this
transaction as a purchase which will result in the elimination of the minority
interest liability reflected on the combined balance sheet and result in
additional amortization of approximately $2,500 per year.
 
17. PRO FORMA ADJUSTMENTS
 
  Statement of Income
 
     Pro forma adjustments are presented to reflect a provision for income taxes
as if AEI had not been an S Corporation for all of the periods presented. Pro
forma net income per common share is based on the weighted average number of
shares outstanding as if the Exchange had occurred at the beginning of the
period presented.
 
  Balance Sheet
 
   
     As discussed in Note 1, the Company reorganized prior to the effective date
of the offering. AEI terminated its S Corporation status at which time
additional deferred tax assets of $1,500 were recorded for existing temporary
differences between the book and tax bases of assets and liabilities. If the
termination of AEI's S Corporation status would have occurred on March 31, 1998,
AEI would have declared a distribution of $35,700 of previously taxed income.
The pro forma balance sheet is presented to reflect these changes as if they
occurred on March 31, 1998.

                          INDEPENDENT AUDITORS' REPORT
 
To the Shareholders and
  Board of Directors
Anam Industrial Co., Ltd.
 
     We have audited the consolidated balance sheets of Anam Industrial Co.,
Ltd. and its subsidiaries (the "Company") as of December 31, 1997 and 1996, and
the related consolidated statements of operations, capital surplus and retained
earnings (accumulated deficit), and cash flows for each of the three years in
the period ended December 31, 1997 (which financial statements are prepared
under generally accepted accounting principles in the Republic of Korea and are
not included in this Registration Statement). These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We did not audit the
financial statements of Anam USA, Inc. ("Anam USA"), a wholly owned subsidiary,
and Anam Engineering and Construction Co., Ltd. ("Anam Construction"), a 59.6%
owned subsidiary, which statements reflect total assets of W913,721 million and
W660,729 million as of December 31, 1997 and 1996, respectively, and total net
income (loss) of W(10,011) million in 1997, W5,738 million in 1996 and W(2,925)
million in 1995. Additionally, we did not audit the financial statements of
Amkor/Anam Pilipinas, Inc. ("AAPI"), a 40% owned affiliate, the investment in
which is reflected in the accompanying financial statements using the equity
method of accounting. The Company's investment in AAPI was W38,612 million and
W19,077 million as of December 31, 1997 and 1996, respectively, and the equity
in its net income (loss) was W(44,491) million in 1997, W2,050 million in 1996
and W(1,570) million in 1995. The aforementioned financial statements were
audited by other auditors whose reports have been furnished to us, and our
opinion, insofar as it relates to the amounts included for Anam USA, Anam
Construction and AAPI, is based solely on the reports of the other auditors. The
auditors of Anam Construction and AAPI expressed uncertainties in their audit
reports about the respective companies' ability to continue as a going concern.
 
     We conducted our audits in accordance with generally accepted auditing
standards in the Republic of Korea, which are substantially the same as those
followed in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits and the reports of
other auditors provide a reasonable basis for our opinion.
 
     In our opinion, based on our audits and the reports of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of Anam Industrial Co., Ltd. and its
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles
in the Republic of Korea.
 
     As discussed in Note 2 to the financial statements, in accordance with
revised Financial Accounting Standards in the Republic of Korea effective in
1997 and 1996, respectively, the Company changed its method of accounting for
unrealized foreign currency translation gains or losses on long-term assets and
liabilities denominated in foreign currencies. In 1997, such gains or losses are
deferred and amortized over the lives or maturities of corresponding assets and
liabilities using the straight-line method. In 1996, such gains or losses had
been recorded as a capital adjustment to shareholders' equity. Prior to 1996,
such gains or losses had been recognized currently.
 
     The financial statements referred to above have been prepared assuming that
the Company will continue as a going concern. As discussed in Note 3 to the
financial statements, the operations of the Company have been significantly
affected, and will continue to be affected for the foreseeable future, by
Korea's unstable economy caused by currency volatility and unstable finance
markets in Korea. The Company has traditionally operated with a significant
amount of debt relative to its equity and has a significant working capital
deficit at
 
                                      F-26
<PAGE>   107
 
December 31, 1997. Because of Korea's unstable economy and the Company's
dependence on debt financing, there are significant uncertainties that may
affect the Company's future operations and its ability to maintain or refinance
certain debt obligations as they mature, which raise substantial doubt regarding
the Company's ability to continue as a going concern. The ultimate outcome of
these uncertainties cannot be determined presently and the financial statements
do not include any adjustments that might result from these uncertainties.
Management's plans to address these matters are also included in Note 3.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders
Anam Engineering & Construction Co., Ltd.
 
     We have audited the balance sheets of Anam Engineering & Construction Co.,
Ltd. (the Company) as of December 31, 1997, 1996 and 1995, and the related
statements of operations and accumulated deficit and cash flows for the years
then ended (not included in this Prospectus or elsewhere in this Registration
Statement). These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards in the Republic of Korea which are substantially the same as those
followed in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Anam Engineering &
Construction Co., Ltd. as of December 31, 1997, 1996 and 1995, and the results
of its operations and the changes in its accumulated deficit and its cash flows
for the years then ended, in conformity with generally accepted financial
accounting standards in the Republic of Korea.
 
     The financial statements referred to above have been prepared assuming that
the Company will continue as a going concern. As discussed in Note 20 to the
financial statements, the operations of the Company have been significantly
affected, and will continue to be affected for the foreseeable future, by
Korea's unstable economy caused by the currency volatility and unstable
financial markets in Korea. The Company has traditionally operated with a
significant amount of debt relative to its equity. Because of Korea's unstable
economy and the Company's dependence on debt financing, there are significant
uncertainties that may affect the Company's future operations and its abilities
to maintain or regarding the Company's ability to continue as a going concern.
The ultimate outcome of these uncertainties cannot be determined presently and
financial statements do not include adjustments that might result from these
uncertainties.
 
     As discussed in Note 17 to the financial statements, the Company executed a
merger in which the operations of Hanyong Corporation were combined with the
Company as of July 31, 1997. This merger was accounted for as a transfer of
assets and liabilities under common control at historical costs in a manner
similar to a pooling of interest of U.S. GAAP reporting purposes.
 
     As discussed in Note 14 to financial statements, the Company sells its
product to Anam Semiconductor Inc. (Anam Industrial Co., Ltd.) and other
affiliated companies. The amounts of sales are W244,013 million, W313,894
million and W47,109 million during the year ended December 31, 1997, 1996 and
1995, and balances of account receivable are W31,844 million, W53,816 million
and W79,316 million at December 31, 1997, 1996 and 1995 respectively and
balances of account payable are W4,834 million, W122 million and W403 million at
December 31 of 1997, 1996 and 1995, respectively.
 
     The amounts expressed in U.S. Dollars, presented solely for the convenience
of the reader, have been translated on the basis set forth in Note 3 to
financial statements.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.
 
     The Company's Amended and Restated Certificate of Incorporation provides
for the indemnification of directors to the fullest extent permissible under
Delaware law.
 
     The Company's Bylaws provide for the indemnification of officers, directors
and third parties acting on behalf of the Company if such person acted in good
faith and in a manner reasonably believed to be in and not opposed to the best
interest of the Company, and, with respect to any criminal action or proceeding,
the indemnified party had no reason to believe his conduct was unlawful.
 
     The Company has entered into indemnification agreements with its directors
and executive officers, in addition to indemnification provided for in the
Company's Bylaws, and intends to enter into indemnification agreements with any
new directors and executive officers in the future.
 
     The form of Underwriting Agreement entered into in connection with the
Company's Initial Public Offering provides for the indemnification of the
Company's directors and officers in certain circumstances as provided therein.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     Prior to the Initial Public Offering, 82,610,000 shares of Common Stock
were issued to Mr. James Kim and members of his family in exchange for their
outstanding interests in the Amkor Companies. Such issuances were made pursuant
to an exemption from registration under Section 4(2) of the Securities Act of
1933, as amended. See "Reorganization" in Part I hereof. The recipients of
securities in each such transaction represented their intention to acquire the
securities for investment only and not with a view to or for sale in connection
with any distribution thereof and appropriate legends were affixed to the share
certificates issued in such transactions. All recipients had adequate access,
through their relationships with the Company, to information about the Company.

ITEM 17. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described in Item 14 above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
                                      II-3
<PAGE>   115
 
the Registrant of expenses incurred or paid by a director, officer, or
controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933, and will be governed by the final adjudication of such
issue.
 
     The undersigned Registrant undertakes that: (1) for purposes of determining
any liability under the Securities Act of 1933, the information omitted from the
form of prospectus as filed as part of the registration statement in reliance
upon Rule 430A and contained in the form of prospectus filed by the Registrant
pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be
deemed to be part of this registration statement as of the time it was declared
effective, and (2) for the purpose of determining any liability under the
Securities Act of 1933, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes:
 
     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
          (i) To include any prospectus required by section 10(a)(3) of the
     Securities Act.
 
          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective registration statement.
 
          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement.
 
     (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof;
 
     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering; and
 
     (4) That, for purposes of determining any liability under the Securities
Act, each filing of the registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
