U.S. Securities and Exchange Commission 3 NOTE 1. GENERAL (2) REORGANIZATION PROCEEDINGS, PAGE F-13 4. WE NOTE THAT YOUR ORIGINAL AND MODIFIED REORGANIZATION PLANS WERE APPROVED BY THE BANKRUPTCY COURT ON JANUARY 9, 2004 AND APRIL 29, 2005, RESPECTIVELY. TELL US HOW YOU CONSIDERED APPLYING FRESH START REPORTING UPON APPROVAL OF YOUR REORGANIZATION PLANS. IN ADDITION TELL US HOW YOU CONSIDERED REPORTING TRANSACTIONS AND EVENTS THAT ARE DIRECTLY ASSOCIATED WITH THE REORGANIZATION (E.G. PRE AND POST PETITION LIABILITIES, CHARGES RELATING TO THE REORGANIZATION, ETC.) SEPARATELY FROM ONGOING OPERATIONS IN YOUR FINANCIAL STATEMENTS. WE REFER YOU TO SOP 90-7. RESPONSE: The Company's understanding of Fresh Start Reporting and the other requirements of SOP 90-7 is that they are applicable to companies that are reorganized under US bankruptcy laws. The Company further understands that the staff has not objected to the application of SOP 90-7 by companies that reorganize under foreign (non U.S.) bankruptcy laws. Because of the differences between US bankruptcy laws and Korean bankruptcy laws, the Company elected not to apply the Fresh Start Accounting requirements of SOP 90-7. Because the Company did not apply Fresh Start Accounting, pre- and post-petition liabilities and charges relating to the reorganization were considered part of ongoing operations in the Company's financial statements. Charges relating to the reorganization have been expensed as incurred. NOTE 7 - DEBTS, PAGE F-25 5. WE NOTE YOUR DISCLOSURE ON PAGE F-26 (LAST PARAGRAPH OF NOTE 7) THAT ALL LONG-TERM DEBTS ARE TO BE REPAID IN 2005. CONSIDERING THIS, TELL US WHY (WON) 11,127 MILLION OF LONG-TERM DEBT AS OF DECEMBER 31, 2004 IS NOT CLASSIFIED AS A CURRENT LIABILITY. RESPONSE: The Company's disclosure on Page F-26 relating to the full repayment of long-term debts refers to the modified reorganization plan approved on April 29, 2005. As disclosed, the modified reorganization plan required repayment of all long-term debt in 2005. As of the end of 2004 (before the approval of modified reorganization plan), however, long-term debts of (pound)U11,127 million were to be repaid according to the original repayment schedule. The Company believes its accounting analogous to scenario 1, 2 and 3 in EITF 86-30 "Classification of Obligations When a Violation Is Waived by the Creditor". These scenarios allow for the debt to be classified as noncurrent, so long as disclosure is made regarding any adverse consequences. * * * U.S. Securities and Exchange Commission 4 The Company acknowledges that it is responsible for the adequacy and accuracy of the disclosure in its filings with the Commission. The Company further acknowledges that staff comments or changes to the Company's disclosure in response to staff comments do not foreclose the Commission from taking any action with respect to the Company's filings with the Commission.
