REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Participants and Administrator of Amkor Technology, Inc. 401(k) Plan:

In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of Amkor Technology, Inc. 401(k) Plan (the “Plan”) at December 31, 2006 and 2005, and the changes in net assets available for benefits for the year ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at year end) as of December 31, 2006 is presented for the purpose of additional analysis and is not a required part of the basic financial statements but are supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

AMKOR TECHNOLOGY, INC. 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006 AND 2005

1. DESCRIPTION OF THE PLAN

The following description of the Amkor Technology, Inc. 401(k) Plan (the “Plan”) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan covering substantially all employees of Amkor Technology, Inc. (the “Employer” or “Company”) on the first day of the month following date of hire. The Plan is intended to comply with the applicable requirements of the Internal Revenue Code of 1986, as amended (the “IRC”) and the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

Administration

Under ERISA, the Employer is the designated administrator of the Plan and has exclusive authority and responsibility for all matters in connection with the operation and administration of the Plan (excluding the authority and responsibility to invest, manage and control the assets of the Plan specifically allocated to the trustee). The Employer has contracted with The Vanguard Group (“Vanguard”) and its affiliates to maintain participants’ Plan accounts and to provide certain other recordkeeping and administrative services for the Plan. Vanguard also serves as the Plan’s trustee.

The Employer has paid certain expenses incurred in the administration of the Plan. Such expenses are primarily comprised of legal, accounting and auditing fees.

Employee Contributions

Participants may elect to defer up to 60% of their eligible compensation (as defined in the Plan) each year, subject to IRC limits. Participants may also contribute amounts representing eligible distributions from other qualified plans.

Each year, the Employer contributes non-discretionary matching deferral contributions in an amount equal to 75% of each participant’s deferral contributions to the Plan, not to exceed $6,000. Plan participants must complete one year of service to be eligible for Employer matching contributions. The Employer may also make annual discretionary matching contributions.

Salary deferral agreements shall be made, terminated, or changed according to procedures and limitations set up by the Plan administrator and the Plan document. Participants currently entitled to receive retirement benefits from another qualified retirement plan may elect to transfer that benefit into a rollover contribution amount under the Plan. Participants may designate the percentage of their total contribution, including the Company’s matching portion, to be invested in any of the funds in which the Plan invests. Participants can change investment elections and contributions percentages at any time.

Participant Accounts

Each participant’s account is credited with the participant’s contributions, any qualified rollover contributions and Employer matching contributions and an allocation of Plan earnings or losses and administrative expenses, if applicable. Allocations of Plan earnings or losses are based on participant account balances. The benefit to which a participant is entitled is the balance of the participant’s vested account.

Withdrawals

While employed with the Company, participants must reach the age of 59¹/2 to withdraw Employer matching contributions. Participant contributions may be withdrawn at age 59¹/2; earlier withdrawals will be subject to an additional 10% tax unless such withdrawals are made due to death, disability, severance of employment after age 55, or a financial hardship as determined by the Plan.

4

Vesting

Participants are immediately vested in their contributions plus actual earnings (if any) thereon. Vesting in Employer matching contributions plus actual earnings (if any) thereon is based on participants’ years of credited service. A participant is 34% vested after one year of credited service, 67% vested after two years of credited service and 100% vested after three years of credited service.

Active participants will become fully vested in Employer matching contributions if they reach normal retirement age (age 59), become disabled (as defined in the plan), or die.

Forfeitures

Forfeitures occur when a participant who is not 100% vested in Employer contributions elects to withdraw from the Plan. At December 31, 2006 and 2005, forfeited nonvested accounts totaled $78,142 and $33,020, respectively, and are available to reduce the future Employer matching contributions or pay administrative expenses. In 2006, the Employer did not use any of the forfeited nonvested accounts to reduce its matching contributions and used $29,511 of the forfeited nonvested accounts to pay administrative expenses. In 2005, the Employer used $88,329 of forfeited nonvested accounts to reduce its matching contributions and used $19,029 of forfeited nonvested accounts to pay administrative expenses.

Contributions

Participant contributions are recognized in the period during which the Employer makes the respective payroll deduction. Employer contributions are recognized as matched by the Employer with the employee contributions.

Rollovers

Participants are allowed to rollover balances from other qualified plans into the Plan.

Payment of Benefits

On termination of service, a participant may generally elect to leave his or her account balance in the Plan, or receive a lump-sum distribution of his or her vested account balance. If a terminated participant’s vested account balance is between $1,001 and $5,000 the sum is a rolled into a Vanguard IRA. If the terminated participant’s vested account balance is less than $1,000, a lump sum distribution of the participant’s vested account balance will automatically be made.

Investment Options

Assets of the Plan are held by Vanguard and are invested in the investment options available under the Plan based on instructions received from participants. The Plan offers a number of options for the investment of participants’ Plan accounts, including various mutual funds, a common/collective trust, and an employer common stock fund.

Administrative Expenses

Administrative expenses are payable from Plan assets unless paid by the Employer, as provided by the Plan document. During 2006 and 2005, administrative expenses incurred by the Plan amounted to $32,389 and $28,479, respectively, while those paid by the employer amounted to $41,000 and $38,500, respectively.

Assets Transferred Out To Other Plans

During 2005, Amkor sold its Wichita, Kansas based Test Services business to Integra Technologies, LLC (“Integra”). After the sale, Plan assets totaling $3,788,808 applicable to the affected employees were transferred to a new plan established by Integra.

2. SUMMARY OF ACCOUNTING POLICIES

Basis of Presentation

The financial statements of the Plan are presented on the accrual basis of accounting in accordance with general accepted accounting principles.

5

Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make significant estimates and assumptions that affect the reported amounts of net assets available for benefits and changes therein. Accordingly, actual results could differ from those estimates.

As described in Financial Accounting Standards Board Staff Position, FSP AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans (the “FSP”), investment contracts held by a defined-contribution plan are required to be reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined-contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the plan. As required by the FSP, the Statement of Net Assets Available for Benefits presents the fair value of the investment contracts as well as the adjustment of the fully benefit-responsive investment contracts from fair value to contract value. The Statement of Changes in Net Assets Available for Benefits is prepared on a contract value basis.

Investment Valuation and Income Recognition

The Plan’s investments are stated at fair value and contract value as of the last business day of the year. Shares of Amkor Technology, Inc. common stock are valued at quoted market prices. Shares of registered investment companies (mutual funds) are valued at quoted market prices which represent the net asset value of shares held by the Plan at year-end. Investments in a common/collective trust are valued at fair value and contract value. Participant loans receivable are valued at their outstanding balances which approximates fair value.

Purchases and sales of securities are recorded on a trade-date basis. Gain or loss on sale of securities is based on average cost. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

Risks and Uncertainties

As described in Note 1, the Plan provides for various investment options such as stocks, mutual funds, and other investment securities. Such investments are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the value of certain investments, it is at least reasonably possible that changes in risks in the near term would materially affect participants’ account balances and the amounts reported in the statement of net assets available for benefits and the statement of changes in net assets available for benefits.

Payment of Benefits

Benefits are recorded when paid. No amounts are owed at December 31, 2006 and 2005 to participants who have elected to withdraw from the Plan, but have not been paid.

New Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board issued Statement on Financial Accounting Standards No. 157, Fair Value Measurements (“SFAS No.157”). This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of December 31, 2006, the Plan does not believe the adoption of SFAS No. 157 will impact the financial statement amounts, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements on changes in net assets for the period.

In September 2006, the Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (“SAB 108”). SAB 108 provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. The SEC staff believes that registrants should quantify errors using both a balance sheet and an income statement approach and evaluate whether either approach results in quantifying a misstatement that, when all relevant quantitative and qualitative factors are considered, is material. SAB 108 is effective for the Plan’s fiscal year ended December 31, 2006. The adoption of SAB 108 did not have a material effect on the Plan’s financial statements.

3. PARTICIPANT LOANS RECEIVABLE

Participants may borrow from their accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 (less their highest outstanding loan balance during the prior 12 months) or 50% of their vested account balance. Loan terms range from 1-5 years or up to 10 years for the purchase of a primary residence. The loans are secured by the balance in the participant’s account and bear interest at a rate commensurate with local prevailing market rates. Outstanding loans at December 31, 2006 carry interest rates ranging from 5% to 10.5%. Principal and interest are paid ratably through

6

monthly payroll deductions. Loans are due, payable in full within 90 days of a participant’s termination of employment.

4. EMPLOYER CONTRIBUTION RECEIVABLE

The Employer inadvertently excluded a limited group of expatriates and foreign nationals from participating in the Plan who were eligible under the terms of the Plan. In accordance with published guidance from the Internal Revenue Service, the Employer will correct the inadvertent exclusion of these individuals by making corrective contributions to the Plan on their behalf. The receivable reflects the aggregate of the corrective contributions to be made to the Plan on behalf of the excluded individuals.

5. PLAN TERMINATION

Although it has not expressed any interest to do so, the Employer has the right under the Plan to terminate or modify the Plan at any time and for any reason subject to the provisions of ERISA. In the event of plan termination, participants will become 100% vested in their accounts.

6. TAX STATUS

The Plan obtained its latest determination letter dated August 22, 2001, in which the Internal Revenue Service stated that the Plan, as then designed was in compliance with the applicable requirements of the IRC. The Plan administrator believes that the amended Plan continues to be designed and is being operated in compliance with the applicable requirements of the IRC in order to maintain its tax-exempt status. Therefore, a provision for income taxes has not been included in the Plan’s financial statements.

7. INVESTMENTS

Investments that represent 5% or more of the Plan’s net assets as of December 31, 2006 and 2005 are separately identified as follows:

	2006		2005

	2006		2005
Amkor Tech Stock Fund	$	4,233,299	$	(134,792	)
Shares of registered investment companies		4,368,588		2,019,016
	$	8,601,887	$	1,884,224

8. RELATED PARTY TRANSACTIONS

Certain Plan investments are managed by Vanguard, the Plan’s trustee in 2006 and 2005, and, therefore, these transactions qualify as party-in-interest. Such transactions are permitted under the provisions of the Plan and are exempt from the prohibition of party-in-interest transactions under ERISA.

During 2006 and 2005, the Plan paid $35,195 and $19,792 respectively to Vanguard for administrative expenses. As of

7

December 31, 2006, the Plan owes $5,880 to Vanguard related to administrative expenses.

As allowed by the Plan, participants may elect to invest a portion of their accounts in Amkor Tech Stock Fund. See Note 10 for subsequent changes to this provision. The shares of Amkor Technology, Inc. common stock are traded in the open market on the NASDAQ Exchange. In 2006, participants purchased 126,485 shares at a cost of $898,037 and sold 520,945 shares with a market value of $5,058,713. In 2005, participants purchased 841,438 shares at a cost of $3,501,515 and sold 458,848 shares with a market value of $1,895,891.

9. RECONCILIATION OF FINANCIAL STATEMENTS TO FORM 5500

The following is a reconciliation of investments per the financial statements to the Form 5500.

Total Investments Per Financial Statements	$	67,107,840
Adjustment from fair value to contract value for common/collective trust		45,174
Total investments per Form 5500	$	67,153,014

The Plan adopted Financial Accounting Standards Board Staff Position AAG INV -1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans as required for financial statements for annual periods after December 15, 2006.

10. SUBSEQUENT EVENTS

In November of 2006, the Board of Directors of Amkor Technology, Inc., voted to restrict participant investment in, and ultimately liquidate the Amkor Tech Stock Fund. These plan changes were announced to be phased in as follows:

• As announced on March 26, 2007, Plan participants were no longer able to direct new contributions or company matching funds into the Amkor Tech Stock Fund after 4:00PM Eastern Standard Time on April 30, 2007. Transfer of assets from other plan funds into the Amkor Tech Stock Fund was also restricted after this cut-off date, and the Fund was closed to all new investment assets from any source at that time.

• As announced on April 30, 2007, the Amkor Tech Stock Fund will close at 1:00PM Eastern Standard Time on November 30, 2007. Any participant assets remaining in the Fund after this closing date will be liquidated through numerous transactions, with proceeds based upon the average sale price being reinvested in the Vanguard Retirement Savings Trust.
