REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  F-1 Deloitte & Touche  Taipei, Taiwan  The Republic of China  March 17, 2011  We have also audited, in accordance with the standards of the Public Company Accounting Oversight  Board (United States), the Company’s internal control over financial reporting as of December 31, 2010, based  on the criteria established in Internal Control Integrated Framework issued by the Committee of Sponsoring  Organizations of the Treadway Commission and our report dated March 17, 2011 expressed an unqualified  opinion on the Company’s internal control over financial reporting.  Our audits also comprehended the translation of New Taiwan dollar amounts into U.S. dollar amounts and,  in our opinion, such translation has been made in conformity with the basis stated in Note 3. Such U.S. dollar  amounts are presented solely for the convenience of the readers.  Accounting principles generally accepted in the Republic of China vary in certain significant respects from  accounting principles generally accepted in the United States of America. Information relating to the nature and  effect of such differences is presented in Note 36 to the consolidated financial statements.  As discussed in Note 4 to the consolidated financial statements, the Company early adopted the new  Statement of Financial Accounting Standards No. 41, “Operating Segments” (“SFAS No. 41”) beginning from  September 1, 2009.  In our opinion, such consolidated financial statements present fairly, in all material respects, the financial  position of Chunghwa Telecom Co., Ltd. and subsidiaries as of December 31, 2009 and 2010, and the results of  their operations and their cash flows for the years ended December 31, 2008, 2009 and 2010, in conformity with  accounting principles generally accepted in the Republic of China.  We conducted our audits in accordance with auditing standards generally accepted in the Republic of China  and 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. 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.  We have audited the accompanying consolidated balance sheets of Chunghwa Telecom Co., Ltd. and  subsidiaries (the “Company”) as of December 31, 2009 and 2010, and the related consolidated statements of  income, changes in stockholders’ equity, and cash flows for the years ended December 31, 2008, 2009 and  2010, all expressed in New Taiwan dollars. 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.  To the Board of Directors and Stockholders of  Chunghwa Telecom Co., Ltd.
