ITEM 4. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT PREVIOUS INDEPENDENT ACCOUNTANTS Effective September 30, 2003, SyCip Gorres Velayo & Co. ("SGV"), a member practice of Ernst & Young Global, was replaced as external auditors of our wholly owned subsidiary, Amkor Technology Philippines, Inc. ("ATP"). SGV became a member practice of Ernst & Young Global beginning September 1, 2002. SGV was a member firm of Arthur Andersen at the time it provided its report on the combined financial statements of Amkor Technology Philippines (P1/P2), Inc. and Amkor Technology Philippines (P3/P4), Inc., which were the predecessor entities of ATP. PricewaterhouseCoopers LLP ("PwC"), our principal accountant, relied in its report on our consolidated financial statements on SGV's report on the financial statements of ATP as of and for the year ended December 31, 2002 and on SGV's report on the combined financial statements of ATP's predecessor entities as of and for the fiscal years ended December 31, 2001 and 2000. The replacement was approved by the Audit Committee of our Board of Directors. PwC, through one of its member firms, will expand the scope of its services to include the audit of ATP for the year ending December 31, 2003. The independent auditors' reports of SGV on the financial statements of ATP or on the combined financial statements of its predecessor entities during the two most recent fiscal years ended December 31, 2002 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During our two most recent fiscal years and through September 30, 2003, we had no disagreements with SGV on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which, if not resolved to the satisfaction of SGV, would have caused it to make a reference to the subject matter of the disagreement in connection with its reports. During our two most recent fiscal years and through September 30, 2003, there have been no "reportable events" as defined in Item 304(a)(1)(v) of Regulation S-K. We have provided SGV with a copy of this disclosure, and we requested that SGV furnish us with a letter addressed to the Securities and Exchange Commission ("SEC"), stating whether it agrees with the above statements. A copy of SGV's letter to the SEC, dated September 30, 2003, is filed as Exhibit 16.1 to this Form 8-K. ITEM 7.
