 To announce the differences between financial
statements for the three months ended March 31, 2022
under Taiwan-IFRSs and that under IFRSs

1.Date of occurrence of the event: 2022/05/06
2.Year/Quarter of the financial report: The first quarter of 2022
3.Accounting principles applied for securities listed domestically:
 Regulations Governing the Preparation of Financial Reports by Securities
 Issuers and International Accounting Standard 34 "Interim Financial
 Reporting" endorsed and issued into effect by the Financial Supervisory
 Commission of the Republic of China ("Taiwan-IFRSs")
4.Inconsistent items/amounts in financial reports for securities listed
domestically:
 Under Taiwan-IFRSs, Chunghwa Telecom Co., Ltd. and its subsidiaries (or
 the "Company") reported consolidated net income of NT$9,390,977 thousand,
 consolidated net income attributable to stockholders of the parent of
 NT$9,059,580 thousand, and basic earnings per share of NT$1.17 for the
 three months ended March 31, 2022, respectively. The Company also reported
 total consolidated assets of NT$518,374,993 thousand, total consolidated
 liabilities of NT$117,992,156 thousand, and total consolidated equity of
 NT$400,382,837 thousand as of March 31, 2022.
5.Accounting principles applied for securities issued overseas:
 IAS 34 "Interim Financial Reporting" as issued by the International
 Accounting Standards Board ("IFRSs")
6.Inconsistent items/ amounts (securities issued overseas):
 Under IFRSs, the Company reported consolidated net income of NT$8,893
 million, consolidated net income attributable to stockholders of the parent
 of NT$8,580 million, and basic earnings per share of NT$1.11 for the three
 months ended March 31, 2022, respectively. The Company also reported total
 consolidated assets of NT$518,174 million, total consolidated liabilities
 of NT$120,420 million, and total consolidated equity of NT$397,754 million
 as of March 31, 2022.
7.Inconsistent items/amounts in financial information for securities issued
overseas:
 The differences between consolidated net income under Taiwan-IFRSs and that
 under IFRSs followed by the Company mainly come from the timing of the
 recognition of income tax on unappropriated earnings. In addition, prior
 to incorporation, the Company was subject to the laws and regulations
 applicable to state-owned enterprises in Taiwan which differed from the
 generally accepted accounting principles as applicable to commercial
 companies. As such, revenue from providing fixed line connection service
 and selling prepaid phone cards was recognized at the time the service was
 performed or the card was sold by the Company. Upon incorporation, net
 assets greater than the capital stock was credited as additional
 paid-in-capital and part of the additional paid-in-capital was from the
 unearned revenues generated from connection fees and prepaid cards as of
 the date of incorporation. Under IFRSs, revenue from connection fees and
 prepaid phone cards was deferred at the time of the service performed or
 sale and recognized as revenue over time as the service is continuously
 performed or as consumed. This reclassification from additional
 paid-in capital to retained earnings did not affect total equity.
8.Any other matters that need to be specified:
 Chunghwa Telecom's earnings distribution and stockholders' equity matters
 are in accordance with Taiwan-IFRSs.
