D. Risk Factors

Our business and operations are subject to various risks,
many of which are beyond our control. If any of the risks described below actually occur, our business, financial condition or results of operations could be seriously harmed.

Risks Relating to Our Company and the Taiwan Telecommunications Industry

Extensive
regulation of our industry may limit our flexibility to respond to market conditions and competition, and our business may suffer.

As a telecommunications service provider in Taiwan, we are subject to extensive regulation. See Item 4. Information on the CompanyB. Business OverviewRegulation for a discussion of
the regulatory environment applicable to us. Any changes in the regulatory environment applicable to us may adversely affect our business, financial condition and results of operations.

##### Table of Contents

For example, the National Communications Commission, or the NCC, submitted a proposal to the
Executive Yuan on July 30, 2012 for an amendment to the Telecommunications Act. This proposed amendment includes several provisions made against the operation of dominant telecommunication service providers, such as the mandatory segregation of
financial data, price control, separation between the underlying network infrastructure and services provision of the last-mile technology and the requirement for dominant providers to release local loops and provide relevant sharing services. These
requirements would allow all telecommunications service providers to have access to our last-mile network infrastructure. The above proposal was later returned by the Executive Yuan to the NCC on October 5, 2012 for consideration, and the NCC
will submit an alternative proposed amendment to the Executive Yuan. We believe the amendment will still take a strict approach on dominant operators and may have a material impact on us once approved.

On the other hand, the Legislative Yuan is reviewing the proposed amendments to the three applicable regulations governing broadcasting
industries for relaxing the current restrictions regarding investments in the broadcasting industries by the government and political parties. Pursuant to these amendments, the government may indirectly hold shares in broadcasting companies,
provided that the governments shareholding is no more than 10% and the government does not control such companies. As the Ministry of Transportation and Communications, or MOTC, holds more than 30% of our shares and retains control over our
board, such amendments will not release the current restrictions on us with respect to engaging in the broadcasting business. However, these amendments may benefit our competitors, which could have a material adverse effect on our business prospects
and results of operations.

We have been designated by the government as a dominant provider of fixed communications and
mobile services within the meaning of applicable telecommunications regulations, and as a result, we are subject to special additional requirements imposed by the NCC. For example, the regulation governing the setting and changing of tariffs allows
non-dominant telecommunications service providers greater freedom to set and change tariffs within the range set by the government. If we are unable to respond effectively to tariff changes by our competitors, then our competitiveness, market
position and profitability will be materially and adversely affected. According to the Fixed Network Regulations, we are required to submit a report to the NCC within 20 days after our shareholders approve the entering into, modification or
termination of any contracts regarding leasing of all business, outsourcing of operations or joint operations, the transfer of the whole or substantial part of our business or assets; and taking over of the whole of the business or assets of any
other company which would have significant impact on our operations. The NCC also amended the Wireless Regulations and the Third Generation Mobile Telecommunications Services Regulations on April 3, 2009 to impose a similar requirement
requiring us to submit a report within 20 days after our shareholders approve one of the above matters or our capital reduction. We were subject to the Statute of Chunghwa Telecom Co., Ltd. prior to our privatization. Although we have been
privatized, the Legislative Yuan has not yet abolished the Statute of Chunghwa Telecom Co., Ltd., and at this time, the Statute of Chunghwa Telecom Co., Ltd. is still applicable to us. Under the Statute of Chunghwa Telecom Co., Ltd., the Ministry of
Transportation and Communications has the authority to regulate some aspects of our business. Any such regulation could be burdensome or conflict with regulations of the NCC or may otherwise adversely affect our business, financial condition and
results of operations.

The regulatory framework within which we operate may limit our flexibility to respond to market
conditions, competition or changes in our cost structure. In particular, future decreases in tariff rates could immediately and substantially decrease our revenues. In particular, as a Type I service provider under the Republic of China
Telecommunications Act, or Telecommunications Act, we are constrained in our ability to raise prices. For example, the NCC adopted the first three-year tariff reduction plan from April 2007 to March 2010 and a second three-year tariff reduction plan
from April 2010 to March 2013, resulting in a number of price reductions in the tariff structures relating to our domestic fixed communications and mobile communications services. On February 7, 2013, the NCC announced a new plan for tariff
reductions in wholesale tariffs for IP peering and domestic leased line services, and in monthly fees for fixed-line broadband services (excluding fiber-to-the-home, or FTTH, and fiber-to-the-building, or FTTB) over a period of four years starting
on April 1, 2013. While mobile tariffs were not regulated in the most recent tariff reduction plan, the revised Administrative Rules for Network Interconnection mandated decreases in the mobile interconnection fees over a period of four years
starting on January 5, 2013. In addition, each operator was required by the NCC to submit a mobile voice service tariffs reduction plan along with the interconnection rate reduction plan, and the new decreased mobile voice service tariffs
became effective on April 1, 2013. See Item 5. Operating and Financial Review and ProspectsOverviewTariff adjustments. We cannot assure you that we will not be required to further reduce our tariffs again in the future.
Any mandatory tariff reductions could have a material adverse effect on our revenues.

If we fail to comply with the regulations of the ROC Fair Trade Act, we may be investigated and fined.

As a provider of telecommunication products and services, our business operations are subject to the regulations of
the ROC Fair Trade Act, or the FTA, which is administered and enforced by the ROC Fair Trade Commission, or the FTC. The FTA requires, among other things, that the marketing and promotional materials of a business to be true and not misleading. The
FTA also prohibits a business from participating or engaging in a cartel or other anti-competitive conduct. The FTC has the authority under the FTA to investigate and, where appropriate, impose fines and penalties on a business that violates any
regulations promulgated by the FTA. The consequences of any such violations could have a material adverse effect on our business and results of operations. See Item 4. Information on the CompanyB. Business OverviewRegulation
for a discussion of the FTA applicable to us. We have been investigated and penalized by the FTC in the past and may continue to be investigated or penalized by the FTC in the future if we fail to comply with the relevant regulations. As the FTA
provides the FTC broad discretion to interpret anti-competition actions and enforce the relevant clauses under the FTA, we are unable to predict whether the FTC would initiate investigation on any of our daily business activities or find us liable
for violating the FTA in the future. The investigations of and penalties imposed by the FTC could interrupt our provision of products or services and have a negative impact on our reputation, business operations and results of operations.

If we are unable to obtain and maintain the licenses to operate our business, our business prospects and future results of operations
would be adversely affected.

We operate our businesses with approvals and licenses granted by the government. If
these approvals or licenses are revoked or suspended or are not renewed, or if we are unable to obtain any additional licenses that we may need to operate or expand our business in the manner we desire, then our financial condition and results of
operations, as well as our prospects, will suffer. For example, there are currently three mobile network operators that offer 2G mobile services in Taiwan. The licenses granted by the ROC government authorities for operating 2G mobile services on
the 900MHz and 1800MHz spectrum can be extended to June 2017 based on the operators request for extension, according to the Executive Yuans announcement on November 22, 2010. On November 29, 2011, we filed a request with the
NCC to extend our 2G license to June 2017, which was approved by the NCC on November 14, 2012. The NCC announced that it will publish the regulations for the 4G license (officially announced as a mobile broadband license by the NCC) auction for
technology neutral usage before the end of June 2013 and complete the auction before the end of December 2013. The NCC is expected to allocate 135MHz x 2 spectrum available for the auction. Although we plan to apply for the license and frequency
spectrum for 4G/mobile broadband services, we cannot assure you that we will be able to acquire the license and the frequency spectrum we need for our mobile operations in the future. If we are unable to successfully acquire the rights to use the
frequency spectrum that we need for our future business operations, our business prospects and future results of operations may be adversely affected, and as a result may lead to a material impact on our business revenues.

Increasing market competition may adversely affect our growth and profitability by causing us to lose customers, charge lower tariffs or spend more
on marketing.

Mobile service providers in Taiwan have been offering 3G mobile services for several years. Smart
phones with mobile data packages have become popular in recent years. To attract more high-end data users, the major three mobile operators, including us, have adopted comparable promotion packages to attract and maintain customers. We cannot assure
you that the intensified market competition will not affect our growth and profitability.

We also face increased broadband
competition from cable operators. Cable operators have been using low-priced internet access packages to attract new customers in specific areas and buildings in Taiwan. They have also been upgrading their networks to DOCSIS 3.0 in order to provide
higher speed internet access. DOCSIS refers to Data Over Cable Service Interface Specification, which is an international telecommunications standard that permits the addition of high-speed data transfer to an existing cable TV system. To counter
these developments, we keep migrating more of our ADSL customers to FTTx services and to provide even higher speed fiber to the home, or FTTH access. The government has mandated the digitization of cable television networks by 2014. In addition, the
NCC relaxed the zoning restrictions on service areas for cable operators on July 27, 2012, while cable operators remain subject to the restriction that the market share of any single cable operator cannot exceed 33%. This change will allow
cable operators to provide digital cable services throughout Taiwan, including high definition cable TV with more channels as well as high speed cable modem services. As of now, it is still uncertain whether we will be deemed a cable operator and
subject to the 33% market share restriction. As a result, we could face increased competition for our broadband access services and multimedia on demand, or MOD, IPTV services. If we are unable to compete successfully with the cable operators for
broadband access services and MOD businesses, our results of operations could be impacted.

Many of our competitors are in
alliances with leading international telecommunications service providers and have access to financial and other resources or technologies that may not be available to us. Moreover, if the government continues to liberalize the telecommunications
market, such as through the issuance of new licenses or establishment of additional networks, our market position and competitiveness could be materially and adversely affected. We cannot guarantee that our measures to address competition will be
effective, and therefore our business, financial condition and results of operations may be adversely affected by our competition.

Increasing competition may also cause the rate of our customer growth to reverse or decline,
bring about further decreases in tariff rates and necessitate increases in our selling and promotional expenses. Any of these developments could adversely affect our business, financial condition and results of operations.

Our ability to deliver services may be disrupted due to a systems failure, shutdown in our networks, earthquakes or other natural disasters.

Taiwan is susceptible to earthquakes and typhoons. However, we do not carry insurance to cover damage caused by
earthquakes, typhoons or other natural disasters or any resulting business interruption. Our services are currently carried through our fixed and mobile communications networks, as well as through our transmission networks consisting of optical
fiber cable, microwave, submarine cable and satellite transmission links, which could be vulnerable to damage or interruptions in operations due to natural disasters. For example, in 2012, losses on property, plant and equipment arising from natural
disasters such as earthquakes and typhoons were approximately NT$7.4 million (US$0.3 million) as recorded in non-operating expenses under ROC GAAP. The occurrence of natural disasters could impact our ability to deliver services and have a negative
effect on our results of operations. Furthermore, we might also be liable for losses claimed from our customers that were incurred from our failure to deliver our services. These potential liabilities could also have a material adverse effect on our
results of operations.

We are subject to litigation that could expose us to substantial liabilities.

We are from time to time involved in litigation, arbitration or administrative proceedings in the ordinary course of our business. See
Item 4. Information on the CompanyB. Business OverviewLegal Proceedings.

We cannot predict the
outcome of these proceedings, and we cannot assure you that if a judgment is rendered against us in any or all of these proceedings, our financial condition and results of operations would not be materially and adversely affected.

We depend on select personnel and could be affected by the loss of their services.

We depend on the continued service of our executive officers and skilled technical and other personnel. Our business could suffer if we
lose the services of any of these personnel and cannot adequately replace them. In particular, we are not insured against the loss of any of our personnel. We may not be able to retain our present personnel or attract additional qualified personnel
as and when needed. Moreover, we may be required to increase substantially the number of these employees in connection with any expansion, and there is intense competition for experienced personnel in the Taiwan telecommunications industry. The
major three mobile network operators in Taiwan, including us, are expanding their retail stores and may increase the number of their employees as part of this expansion. We cannot assure you that we will be able to successfully attract and retain
new employees for the expansion of our retail stores. In addition, we may need to increase employee compensation levels in order to attract and retain personnel. We cannot assure you that the loss of the services of any of these personnel would not
disrupt our business and operations and materially and adversely affect the quality of our services and harm our reputation.

We may not
realize the benefits we expect from our investments, and this may materially and adversely affect our business,  financial condition, results of operations and prospects.

We have made significant capital investments in our network infrastructure and information technology systems to provide the services we
offer. In 2012, we made capital expenditures in our domestic fixed communications of NT$19.6 billion (US$673.0 million), our mobile communications business of NT$7.2 billion (US$249.0 million), our internet business of NT$3.4 billion (US$118.5
million), our international fixed communications business of NT$2.4 billion (US$81.9 million) and our other businesses of NT$0.7 billion (US$23.3 million), respectively. In order to continue to develop our business and offer new and more
sophisticated services, we intend to continue to invest in these areas as well as new technologies. The launch of new and commercially viable products and services is important to the success of our business. We expect to continue making substantial
capital expenditures to further develop our range of services and products. Commercial acceptance by consumers of the new and more sophisticated services we offer may not occur at the rate or level expected, and we may not be able to successfully
adapt these services to effectively and economically meet our customers demand, thus impairing expected return from our investments.

We cannot assure you that services enabled by the new technologies we are implementing, such
as 100Mbps fiber solution and Heterogeneous, or Marco/Micro/Pico/Femto/BBU+RRH/WiFi mobile technology, will be accepted by the public to the extent required to generate an acceptable rate of return. In addition, we could face the risk of
unforeseen complications in the deployment of these new services and technologies, and we cannot assure you that we will not exceed our estimate of the necessary capital expenditure to offer such services. New services and technologies may not be
developed and/or deployed according to expected schedules or may not achieve commercial acceptance or be cost effective. The failure of any of our services to achieve commercial acceptance could result in additional capital expenditures or a
reduction in profitability to the extent we are required under applicable accounting standards to recognize a charge for impairment of assets. Any such charge could materially and adversely affect our financial condition and results of operations.

In 2012, we determined that parts of our land and telecommunication equipment were impaired and recognized an impairment loss
of NT1,505 million (US$51.8 million). In 2012, we also recognized impairment losses of NT$4.8 million (US$0.2 million), NT$35 million (US$1.2 million) and NT$20 million (US$0.7 million) for intangible assets, idle assets and other assets,
respectively.

We cannot assure you that we will be able to continue to maintain control of and consolidate the results of
operations of our minority-owned subsidiary. For example, we consolidate the results of operations of our subsidiary, Senao, because we have control over the board of directors through the support of the largest beneficial shareholder. We cannot
assure you that we will be able to continue maintaining control over the board of directors of Senao. See Item 4. Information on the CompanyB. Business OverviewMobile Communications BusinessSales of Mobile Handsets for
further discussion of our control of Senao. If we lose control of our minority-owned subsidiary, we will no longer be able to consolidate the results of operations of such subsidiary, which could adversely affect our consolidated results of
operations and ability to meet the operating results guidance that we have projected.

We may also from time to time make
equity investments in companies, but we cannot assure you of their profitability. We cannot assure you that losses related to our equity investments will not have a material adverse effect on our financial condition or results of operations. In
2012, we recognized other-than-temporary impairment losses of NT$27 million (US$0.9 million) for available-for-sale financial assets due to the decline in market prices, the time of recovery of which we cannot estimate, and of NT$176 million (US$6.1
million) for financial assets carried at cost due to adverse changes in industry conditions and operating performance that were below expectations. We may be required to record additional impairment charges in future periods, which may have a
material adverse effect on our financial condition and future results of operations.

Changes in technology may render our current
technologies obsolete or require us to obtain licenses for introducing new services or make substantial capital investments, financing for which may not be available to us on favorable commercial terms or at all.

The Taiwan telecommunications industry has been characterized by rapid increases in the diversity and sophistication of the technologies
and services offered. As a result, we expect that we will need to constantly upgrade our telecommunications technologies and services in order to respond to competitive industry conditions and customer requirements. Developments of new technologies
have rendered some less advanced technologies unpopular or obsolete. If we fail to develop, or obtain timely access to, new technologies and equipment, or if we fail to obtain the necessary licenses to provide services using these new technologies,
we may lose our customers and market share and become less profitable.

In addition, the cost of implementing new technologies, upgrading our networks or expanding
capacity could be significant. In particular, we have made and will continue to make substantial capital expenditures in the near future in order to effectively respond to technological changes, such as the continued expansion of our fiber optic
networks and High Speed Packet Access, or HSPA, and HSPA+, and Dual cell HSPA+ mobile network. Furthermore, the 4G/mobile broadband licenses are scheduled to be awarded by the end of 2013. Therefore, we expect to devote additional capital
expenditure to the network building for Long Term Evolution, or LTE, network. In addition, to meet the increasingly robust high-bandwidth requirements of digital convergence services, we will expand construction of fiber optic networks, including
passive optical networks, or PONs, and optical distribution networks, or ODNs. To the extent these expenditures exceed our cash resources, we will be required to seek additional debt or equity financing. Our ability to obtain additional financing on
favorable commercial terms will depend on a number of factors. These factors include our financial condition, results of operations, cash flows and the prevailing market conditions in the domestic and international telecommunications industry, the
cost of financing and conditions in the financial markets, and the issuance of relevant government and other regulatory approvals. Any inability to obtain funding for our capital expenditures on commercially acceptable terms could jeopardize our
expansion plans and materially and adversely affect our business prospects and future results of operations.

If new technologies
adopted by us do not perform as expected, or if we are unable to effectively deliver new services based on these technologies in a commercially viable manner, our revenue growth and profitability will decline.

We are always evaluating new growth opportunities in the broader telecommunications industry and expect to become an Information and
Communications Technology, or ICT, service provider. Some of these opportunities involve new services for which there are no proven markets, and may not develop as expected. Our ability to deploy and deliver these services will depend, in many
instances, on new but unproven technologies. These new technologies may not perform as expected or generate an acceptable rate of return. In addition, we may not be able to successfully develop new technologies to effectively and economically
deliver these services, or be able to compete successfully in the delivery of telecommunications services based on new technologies. Furthermore, the success of our mobile data services is substantially dependent on the availability of mobile data
applications and devices that are being developed by third-party developers. These applications or devices may not be sufficiently developed to support the deployment of our mobile data services. If we are unable to deliver commercially viable
services based on the new technologies that we adopt, our financial condition and results of operations may be materially and adversely affected.

As an internet service provider, we may not be able to protect our customers and their information from cyber attacks, nor protect our services from disruptions due to cyber security breaches.

As an internet service provider, our system is susceptible to cyber security risks, including hijack attacks,
phishing attacks, hackers intrusions to steal customers information and distributed denial-of-service (DDoS) attacks. Our online services such as e-bills and multiple payment options through the internet are also vulnerable to cyber
attacks. These attacks may disrupt our services and cause leakage of our customers personal information, which may result in significant damage and material adverse effect to our customers and our operations. We cannot assure you that our data
protection measures are sufficient to prevent any data leakage or disruption of our service due to cyber attacks. We may suffer negative consequences, such as remedial costs, increased cyber security protection costs, lost revenues, litigation and
reputational damage due to cyber attacks.

Our largest stockholder may take actions that conflict with our public stockholders
best interests.

As of December 31, 2012, our largest shareholder, the government of the Republic of China,
through the Ministry of Transportation and Communications, owned approximately 35.29% of our outstanding common shares. Accordingly, the government, through its control over our board, as all non-independent board members were appointed by the
Ministry of Transportation and Communications, may continue to have the ability to control our business, including matters relating to:



| |  |  | any sale of all or substantially all of our assets;
| | - |  | ---------------------------------------------------



| |  |  | the approval of our annual operation and projects budget;
| | - |  | ---------------------------------------------------------

We cannot assure you that our largest shareholder will not take actions that impair our ability to conduct our business competitively or conflict with the best interests of our public stockholders.

Actual or perceived health risks related to mobile handsets and base stations could lead to decreased mobile service usage and
difficulties in increasing network coverage and could expose us to potential liability.

According to some published
reports, the electromagnetic signals from mobile handsets and cellular base stations may pose health risks or interfere with the operation of electronic equipment. Although the findings of those reports are disputed, actual or perceived risks of
using mobile communications devices or of cellular base stations could have a material adverse effect on mobile service providers, including us. For example, our customer base could be reduced, our customers may reduce their usage of our mobile
services, we could encounter difficulties in obtaining sites for additional cellular base stations required to expand our network coverage or we may be requested to reduce the number of existing cellular base stations. As a result, our mobile
services business may generate less revenue and our financial condition and results of operations may be materially and adversely affected. In addition, we could be exposed to potential liability for any health problems caused by mobile handsets and
base stations.

Investor confidence in us may be adversely impacted if we or our independent registered public accountants are unable to
attest to or express an unqualified opinion on the effectiveness of our internal control over financial reporting.

We
are subject to the reporting requirements of the SEC. The SEC, as directed by Section 404 of the U.S. Sarbanes-Oxley Act of 2002, adopted rules requiring U.S. public companies to include a report of management on our internal control over
financial reporting in their annual reports that contain an assessment by management of the effectiveness of our internal control over financial reporting. The effectiveness of our internal control over financial reporting has been audited by
Deloitte & Touche, an independent registered public accounting firm, which has also audited our consolidated financial statements for the year ended December 31, 2012. Deloitte & Touche has issued an attestation report on the
effectiveness of our internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). See Item 15. Controls and ProceduresAttestation Report of the Registered
Public Accounting Firm.

While the management report included in this annual report concluded that our internal control
over financial reporting was effective, we cannot assure you that our management will be able to conclude that our internal control over financial reporting is effective in future years. If in future years we fail to maintain effective internal
control over financial reporting in accordance with the Sarbanes-Oxley Act, we could suffer a loss of investor confidence in the reliability of our consolidated financial statements, which in turn could negatively impact the trading price of our
ADSs, result in lawsuits being filed against us by our stockholders or otherwise harm our reputation.

If we fail to maintain a good
relationship with our labor union, work stoppages or labor unrest could occur and the quality of our services as well as our reputation could suffer.

In accordance with the articles of association of Chunghwa Telecom Workers Union, besides the chief manager of each department, most of our employees are members of our principal labor union, the Chunghwa
Telecom Workers Union. Since our incorporation in 1996, we have experienced disputes with our labor union on such issues as employee benefits and retirement benefits in connection with our privatization as well as the right to protest. Despite
having taken measures to improve relations, increase cooperation and ensure mutual benefit with our labor union, such as increasing channels of communications by holding periodic labor resource review meetings and guaranteeing a labor union seat on
our board of directors, we cannot assure you that we will be able to maintain a good relationship with our labor union. Any deterioration in our relationship with our labor union could result in work stoppages, strikes or threats to take such an
action, which could disrupt our business and operations, materially and adversely affect the quality of our services and harm our reputation.

Any further economic downturn or decline in the growth of the population in Taiwan may
materially and adversely affect our financial condition, results of operations and prospects.

We conduct most of our
operations and generate most of our revenues in Taiwan. As a result, any decline in the Taiwan economy or a decline in the growth of the population in Taiwan may materially and adversely affect our financial condition, results of operations and
prospects. For example, the global slowdown in technology expenditures has from time to time adversely affected the Taiwan economy, which is highly dependent on the technology industry. The current European debt crisis and related financial
restructuring efforts, including in Greece, Italy, Spain, Portugal and Ireland, are contributing to instability in global financial markets, which adversely affects consumer confidence, the cost of borrowing and economic activity, and might also
have an impact on the Taiwan economy and hence on our financial condition. Furthermore, there is considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies that have been adopted by the central banks and
financial authorities of some of the worlds leading economies. There have also been concerns over unrest in the Middle East and Africa, which has resulted in higher oil prices and significant market volatility, and concerns about the economic
effect of the earthquake, tsunami and nuclear crisis in Japan.

As our business is significantly dependent on economic growth,
any uncertainty or further deterioration in economic conditions could have a material adverse effect on our financial condition and results of operations. We cannot assure you that economic conditions in Taiwan will continue to improve in the future
or that our business and operations will not be materially and adversely affected by deterioration in the Taiwan economy.

We face
substantial political risks associated with doing business in Taiwan, particularly due to domestic political events and the tense relationship between the Republic of China and the Peoples Republic of China, which could adversely affect our
financial condition and results of operations.

Our principal executive offices and substantially all of our assets
are located in Taiwan, and substantially all of our revenues are derived from our operations in Taiwan. Accordingly, our business, financial condition and results of operations and the market price of our common shares and the ADSs may be affected
by changes in Republic of China governmental policies, taxation, inflation or interest rates and by social instability and diplomatic and social developments in or affecting Taiwan which are outside of our control. Taiwan has a unique international
political status. Since 1949, Taiwan and the Chinese mainland have been separately governed. The Peoples Republic of China, or PRC, claims that it is the sole government in China and that Taiwan is part of China. Although significant economic
and cultural relations have been established between the Republic of China and the PRC, such as the engagement of the Economic Cooperation Framework Agreement, or ECFA, in 2010, relations may become strained again. The PRC government has refused to
renounce the use of military force to gain control over Taiwan. Past developments in relations between the Republic of China and the PRC have on occasion depressed the market prices of the securities of companies in the Republic of China. Relations
between the Republic of China and the PRC and other factors affecting military, political or economic conditions in Taiwan could materially and adversely affect our financial condition and results of operations, as well as the market price and the
liquidity of our securities. In addition, the complexities of the relationship between the ROC and PRC require companies involved in cross-strait business operations to carefully monitor their actions and manage their relationships with both ROC and
PRC governments. In the past, companies in the ROC, including us, have received minor sanctions such as travel restrictions or minor monetary fines by the ROC and/or PRC governments. We cannot assure you that we will be able to successfully manage
our relationships with the ROC and PRC governments for our cross-strait business operations, which could have an adverse effect on our ability to expand our business and conduct cross-strait business operations.

Any future outbreak of contagious diseases may materially and adversely affect our business and operations, as well as our financial
condition and results of operations.

Any future outbreak of contagious diseases, such as severe acute respiratory
syndrome or avian influenza, may disrupt our ability to adequately staff our business and may generally disrupt our operations. If any of our employees is suspected of having contracted any contagious disease, we may under certain circumstances be
required to quarantine such employees and the affected areas of our premises. As a result, we may have to temporarily suspend part or all of our operations. Furthermore, any future outbreak may restrict the level of economic activity in affected
regions, including Taiwan, which may adversely affect our business and prospects. As a result, we cannot assure you that any future outbreak of contagious diseases would not have a material adverse effect on our financial condition and results of
operations.

Stockholders may have more difficulty protecting their interests under the laws of the Republic of
China than they would under the laws of the United States.

Our corporate affairs are governed by our articles of
incorporation, the Telecommunications Act, and by the laws governing corporations incorporated in the Republic of China. In addition, our corporate affairs may remain governed by the Statute of Chunghwa Telecom Co., Ltd. See Extensive
regulation of our industry may limit our flexibility to respond to market conditions and competition, and our business may suffer. The rights of stockholders and the responsibilities of management and the members of the board of directors of
Taiwan companies are different from those applicable to a corporation incorporated in the United States. For example, controlling or major stockholders of Taiwan companies do not owe fiduciary duties to minority stockholders. As a result, holders of
our common shares and ADSs may have more difficulties in protecting their interests in connection with actions taken by our management or members of our board of directors than they would as public stockholders of a United States corporation.

Our actual financial results may differ materially from our published guidance.

Prior to 2013, we used to voluntarily publish our operating results guidance on an annual basis in accordance with ROC GAAP. Beginning in
2013, we plan to continue voluntarily publishing our operating results guidance on an annual basis in accordance with Taiwan IFRS. We may from time to time update our operating results guidance after evaluating the effects of any changes to the
estimates and assumptions that we used to calculate our projections of our operating results. Our projections are based on a number of estimates and assumptions that are inherently subject to significant uncertainties and contingencies, including
the risk factors described in this annual report. In particular, our projections are forward-looking statements that are necessarily speculative in nature, and it can be expected that one or more of the estimates on which the projections were based
will not materialize or will vary significantly from actual results, and such variances will likely increase over time.

Our results of
operations and financial condition upon the adoption of new financial reporting standards may differ materially  from our reported results of operations and financial condition under ROC GAAP.

The Financial Supervisory Commission, or the FSC, in the ROC, supervises the financial and business matters of publicly-held companies,
and we are required to comply with relevant regulations promulgated by the FSC. We have historically presented our consolidated financial statements, including our consolidated financial statements for the year ended December 31, 2012, in
accordance with ROC GAAP for purposes of our filings with the TWSE, with reconciliation to U.S. GAAP for certain filings with the SEC. Effective January 1, 2013, companies listed on the TWSE, including us, must report their financial statements
under Taiwan IFRS pursuant to the requirements of the Framework for Adoption of International Financial Reporting Standards by Companies in the ROC promulgated by the FSC on May 14, 2009. Accordingly, we have adopted Taiwan IFRS for reporting
in the ROC our annual consolidated financial statements beginning in 2013 and our interim quarterly unaudited consolidated financial statements beginning in the first quarter of 2013. While we have adopted Taiwan IFRS for ROC reporting purposes, we
plan to adopt International Financial Reporting Standards issued by the International Accounting Standards Board, or IFRS, which differs from Taiwan IFRS, for certain filings with the SEC, including our annual reports on Form 20-F for the year
ending December 31, 2013 and thereafter and our interim quarterly unaudited consolidated financial statements beginning with the three months ended March 31, 2013. Following our adoption of IFRS issued by the International Accounting
Standards Board for SEC filing purposes, we will no longer be required to reconcile our consolidated financial statements with U.S. GAAP.

Taiwan IFRS differs from IFRS in certain significant respects, including to the extent that any new or amended standards or interpretations applicable under IFRS may not be timely endorsed by the FSC. In
addition, Taiwan IFRS and IFRS differ in certain significant respects from ROC GAAP. See Item 5. Operating and Financial Review and ProspectsOur Financial Reporting ObligationsRecent Accounting Pronouncements. Because of the
differences in accounting treatments, the adoption of Taiwan IFRS and IFRS may result in material and adverse changes to our results of operations and financial condition in our reported financial statements for the year ending December 31,
2013 and financial statements going forward. Furthermore, the dividends for 2013 that are expected to be declared at our 2014 annual general stockholders meeting will be calculated based on Taiwan IFRS. It is difficult for us to evaluate the
precise impact of the adoption of Taiwan IFRS and IFRS on our financial reporting generally, or on our financial statements for the year ending December 31, 2013 or the year ended December 31, 2012, because the FSC may issue new rules
governing the adoption of Taiwan IFRS and as other laws and regulations may be amended with the adoption of Taiwan IFRS. In addition, under Taiwan IFRS and IFRS, we are required to present the opening balance sheet on the transition date of
January 1, 2012 with adjusted opening balances prepared under Taiwan IFRS and IFRS. Consequently, our consolidated financial statements for the year ended December 31, 2012 to be included in our annual report for the year ending
December 31, 2013 may differ materially from those included in this annual report, even though they relate to the same fiscal year. Similarly, the selected comparison financial information to be included in our quarterly earnings releases in
2013 may also differ materially from those released historically.

Risks Relating to Ownership of Our ADSs and Common Shares

The value of your investment may be reduced by future sales of our ADSs or common shares by us, by the government of the Republic of China or by
other stockholders.

The government may continue to sell our common shares. Sales of substantial amounts of ADSs or
common shares by the government or any other stockholder in the public market, or the perception that future sales may occur, could depress the prevailing market price of our ADSs and common shares.

The market value of your investment may fluctuate due to the volatility of, and government intervention in, the Taiwan securities market.

Our common shares are traded on the Taiwan Stock Exchange, or TWSE, which has a smaller market capitalization and is
more volatile than the securities markets in the United States and many European countries. The market value of our ADSs may fluctuate in response to the fluctuation of the trading price of our common shares on the TWSE. The TWSE has experienced
substantial fluctuations in the prices and trading volumes of listed securities, and there are currently limits on the range of daily price movements. In recent years, the TWSE Index reached a peak of 10,202.20 in February 2000 and subsequently fell
to a low of 3,446.26 in October 2001. During 2012, the TWSE Index peaked at 8,144.04 on March 2, 2012, and reached a low of 6,894.66 on June 4, 2012. On April 12, 2013, the TWSE Index closed at 7,821.63. The TWSE has experienced
certain problems, including market manipulation, insider trading and payment defaults. The recurrence of these or similar problems could have a material adverse effect on the market price and liquidity of the securities of Taiwan companies,
including our ADSs and common shares, in both the domestic and the international markets.

In response to declines and
volatility in the securities markets in Taiwan, the government of the Republic of China formed the National Financial Stabilization Fund to support these markets through open market purchases of shares in Taiwan companies from time to time. The
details of the transactions of the National Financial Stabilization Fund have not been made public. In addition, the governments Labor Insurance Fund and other funds associated with the government have in the past purchased, and may from time
to time purchase, shares of Taiwan companies listed on the TWSE or other markets. As a result of these activities, the market price of common shares of Taiwan companies may have been and may currently be higher than the prices that would otherwise
prevail in the open market. Market intervention by government entities, or the perception that such activity is taking place, may take place or has ceased, may cause sudden movements in the market prices of the securities of Taiwan companies, which
may affect the market price and liquidity of our common shares and ADSs.

We may be sanctioned or lose our licenses for violations of
limits on foreign ownership of our common shares, and these limits may materially and adversely affect our ability to obtain financing.

The laws of the Republic of China limit foreign ownership of our common shares. Prior to March 1, 2006, the Ministry of Transportation and Communications, as the competent authority under the
Telecommunications Act, had the power to prescribe the limits on foreign ownership of our common shares. After the formation of the NCC on March 1, 2006, the NCC replaced the Ministry of Transportation and Communications as the competent
authority under the Telecommunications Act pursuant to the National Communications commission Organization Law, or the Organization Law. The NCC and the Ministry of Transportation and Communications reached an agreement on foreign ownership of
Chunghwa Telecom. An announcement issued by the Ministry of Transportation and Communications on December 28, 2007 stipulated that direct holdings by foreign investors in Chunghwa Telecom cannot exceed 49% of our outstanding share capital and
the total direct and indirect holdings by foreign investors cannot exceed 55% of our outstanding share capital. As of April 12, 2013, foreign direct holdings of our outstanding share capital is at 14.87% . If we fail to comply with the
applicable foreign ownership limitations, our licenses to operate some of our businesses could be revoked. Moreover, we cannot predict the manner in which the NCC will exercise its authority over us, or whether NCC will lower the foreign ownership
cap at any time.

If we are deemed to be in violation of our foreign ownership limitations, any consequences
arising from such violation may materially and adversely affect us. Moreover, since we are unable to control ownership of our common shares or ADSs representing our common shares, and because we have no ability to stop transfers among stockholders,
or force particular stockholders to sell their shares, we may be subject to monetary fine or lose our licenses through no fault of our own. In that event, our business could be disrupted, our reputation could be damaged and the market price of our
ADSs and common shares could decline. These limitations may also materially and adversely affect our ability to obtain adequate financing to fund our future capital requirements or to obtain strategic partners, and alternate forms of financing may
not be available on terms favorable to us or at all.

Restrictions on the ability to deposit our common shares into our ADS
program may adversely affect the liquidity and price of the ADSs.

The ability to deposit shares into our ADS program
is restricted by Republic of China law, under which no person or entity, including you and us, may deposit our common shares into our ADS program unless the Securities and Futures Bureau has not objected within a prescribed period following the
filing with it of an application to do so, except for the deposit of the common shares into our ADS program and for the issuance of additional ADSs in connection with:



| |  |  | distribution of share dividends or free distribution of our common shares;
| | - |  | --------------------------------------------------------------------------



| |  |  | exercise of preemptive rights of ADS holders applicable to the common shares evidenced by our ADSs in the event of capital increases for cash; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | purchases of our common shares in the domestic market in Taiwan by the investor directly or through the depositary and delivery of such shares or
delivery of our common shares held by such investors to the custodian for deposit into our ADS program, subject to the following conditions: (a) the depositary may accept deposit of those shares and issue the corresponding number of ADSs with
regard to such deposits only if the total number of ADSs outstanding after the deposit does not exceed the number of ADSs previously approved by the Securities and Futures Bureau, plus any ADSs issued pursuant to the events described above; and
(b) this deposit may only be made to the extent previously issued ADSs have been cancelled.

result of the limited ability to deposit common shares into our ADS program, the prevailing market price of our ADSs on the New York Stock Exchange may differ from the prevailing market price of the equivalent number of our common shares on the
TWSE.

You will be more restricted in your ability to exercise voting rights than the holders of our common shares, which may diminish
your influence over our corporate affairs and may reduce the value of your ADSs.

Holders of American depositary
receipts evidencing our ADSs may exercise voting rights with respect to the common shares represented by these ADSs only in accordance with the provisions of our deposit agreement. The deposit agreement provides that, upon receipt of notice of any
meeting of holders of our common shares, the depositary bank will, as soon as practicable thereafter if requested by us in writing, mail to ADS holders the notice of the meeting sent by us, voting instruction forms and a statement as to the manner
in which instructions may be given by the holders.

Generally, ADS holders will not be able to exercise voting rights attached to the underlying
securities on an individual basis. Under the deposit agreement, the voting rights attached to the underlying securities must be exercised as to all matters subject to a vote of stockholders collectively in the same manner, except in the case of an
election of directors and supervisors. The election of our directors and supervisors is by means of cumulative voting. In the event the depositary does not receive voting instructions from ADS holders in accordance with the deposit agreement, our
chairman or his or her designee will be entitled to vote the common shares represented by the ADSs in the manner he or she deems appropriate at his or her discretion, which may not be in your interest.

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings.

We may from time to time distribute rights to our stockholders, including rights to acquire our securities. Under the deposit agreement,
the depositary will not offer you those rights unless the distribution to ADS holders of both the rights and any related securities are either registered under the U.S. Securities Act of 1933, as amended, or the Securities Act, or exempt from
registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be
able to establish an exemption from registration under the Securities Act. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

If the depositary is unable to sell rights that are not exercised or not distributed or if the sale is not lawful or reasonably
practicable, it will allow the rights to lapse, in which case you will receive no value for these rights.

Changes in exchange controls
that restrict your ability to convert proceeds received from your ownership of ADSs may have an adverse effect on the value of your investment.

Your ability to convert proceeds received from your ownership of ADSs depends on existing and future exchange control regulations of the Republic of China. Under the current laws of the Republic of China,
an ADS holder or the depositary, without obtaining further approvals from the Central Bank of the Republic of China (Taiwan) or any other governmental authority or agency of the Republic of China, may convert NT dollars into other currencies,
including U.S. dollars, in respect of:



| |  |  | the proceeds of the sale of common shares represented by ADSs or received as share dividends with respect to the common shares and deposited into the
depositary receipt facility; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any cash dividends or distributions received from the common shares represented by ADSs.
| | - |  | ----------------------------------------------------------------------------------------

In addition, the depositary may also convert into NT dollars incoming payments for purchases of common shares for deposit in the
depositary receipt facility against the creation of additional ADSs. If you withdraw the common shares underlying your ADSs and become a holder of our common shares, you may convert into NT dollars subscription payments for rights offerings. The
depositary may be required to obtain foreign exchange approval from the Central Bank of the Republic of China (Taiwan) on a payment-by-payment basis for conversion from NT dollars into foreign currencies of the proceeds from the sale of subscription
rights of new common shares. Although it is expected that the Central Bank of the Republic of China (Taiwan) will grant approval as a routine matter, required approvals may not be obtained in a timely manner, or at all.

Under the Republic of China Foreign Exchange Control Law, the Executive Yuan of the Republic of China may, without prior notice but
subject to subsequent legislative approval rendered within ten days from such imposition, impose foreign exchange controls or other restrictions in the event of, among other things, a material change in domestic or international economic conditions
which might threaten the stability of the domestic economy in Taiwan.

##### Table of Contents

You are required to register with the Taiwan Stock Exchange and appoint several local agents in Taiwan
if you withdraw common shares from our ADS facility and become our stockholder, which may make your ownership burdensome.

If you are a non-Republic of China person and wish to withdraw common shares represented by your ADSs from our ADS facility and hold those common shares, you are required under the current laws and
regulations of the Republic of China to appoint an agent, also referred to as a tax guarantor, in the Republic of China for filing tax returns and making tax payments. A tax guarantor must meet certain qualifications set by the Ministry of Finance
of the Republic of China and, upon appointment, becomes a guarantor of your Republic of China tax obligations. If you wish to repatriate profits derived from the sale of withdrawn common shares or cash dividends or interest on funds derived from the
withdrawn common shares, you will be required to submit evidence of your appointment of a tax guarantor and the approval of the appointment by the Republic of China tax authorities. You may not be able to appoint and obtain approval for a tax
guarantor in a timely manner.

In addition, under the current laws of the Republic of China, you will be required to be
registered as a foreign investor with the TWSE for making investments in the Republic of China securities market prior to your withdrawal and holding of common shares represented by the ADSs. You will be required to appoint a local agent in Taiwan
to, among other things, open a securities trading account with a local securities brokerage firm and a bank account to remit funds, exercise stockholders rights and perform other functions as holders of ADSs may designate. You must also
appoint a local bank to act as custodian for handling confirmation and settlement of trades, safekeeping of securities and cash proceeds and reporting and declaration of information. Without the relevant registration and appointment of the local
agent and custodian and the opening of a securities trading account and bank account, you will not be able to hold, subsequently sell or otherwise transfer our common shares withdrawn from the ADS facilities on the TWSE.

Competitive Strengths

We believe that we are well positioned to take
advantage of the increasing opportunities in the telecommunications market in Taiwan as new technologies evolve. In particular, we have maintained our leading market share in mobile communications and internet services. Furthermore, we have enjoyed
greater flexibility in making purchasing and other business decisions after we were privatized in August 2005.

We believe
that further deregulation and market liberalization will continue to drive the growth of the overall market for telecommunications services in Taiwan, as well as the development of new products and services. We expect to benefit from additional
opportunities as the telecommunications market in Taiwan continues to grow.

We believe that our primary competitive strengths
are:

We have a broad customer base in Taiwan.

We are the largest telecommunications service provider in Taiwan with a broad customer base across all of our service offerings. Despite
deregulation and an increase in competition in the Taiwanese telecommunications industry, we have maintained a market leading position in our primary service offerings of fixed communications, mobile communications and internet services. We believe
our broad customer base in each of our service offerings grants us a distinct competitive advantage to maintain our existing customers and attract new customers and increases the chance of success for the launch and popularization of new products.
As the telecommunications industry continues its trend of converging fixed communications, mobile communications and internet services, we believe that our comprehensive service offerings place us in a strong position to offer converged products and
services to our customers.

We are an integrated full-service telecommunications provider in Taiwan.

We are the largest telecommunications service provider in Taiwan with a leading position in fixed communications services, mobile
communications services and internet services.

Broad range of communications products and services. We believe that
our ability to provide an attractive and comprehensive range of telecommunications services positions us to provide bundled and value-added services to our business and residential customers. In addition, we are able to offer innovative integrated
services and tariff packages to meet the specific needs of our customers.

Broad network coverage. The breadth of our
network and our ownership of the last-mile infrastructure in Taiwan, which comprises the connection between the local telephone service providers switching centers to the end-users buildings or homes, provides us with access
to existing and potential customers and creates a platform for expanding our services. In order to provide higher bandwidth services for our customers, we have been constructing our FTTx network since 2003. We have successfully migrated many of our
customers from lower-speed to higher-speed internet access services and upgraded ADSL subscribers to FTTx, which offers even higher speeds by using fiber optic technology. The number of our FTTx subscribers has exceeded that of our ADSL subscribers
since 2011. As of December 31, 2012, network coverage of FTTx with speeds of 50 Mbps and 100 Mbps was approximately 81.9% and 73.6 %, respectively. In addition, our mobile communications network provides nationwide coverage. Our large
cellular spectrum allocation together with our network of 19,941 base stations positions us well for the continued expansion of our mobile services in Taiwan. We are also continuing to build our Wi-Fi network to offload 3G capacity in residential
areas and public areas where subscriber density and usage is high, such as urban areas, airports and convenience stores.

Brand awareness, distribution channels and customer service. Our principal brands Chunghwa Telecom, emome and HiNet have a reputation for quality and
reliability. We serve our large and well-established customer base through our extensive customer service network in Taiwan, including 17 operations offices, 392 service centers, 238 exclusive service stores and 6 customer service call centers. We
are continuing to expand and transform our retail stores while increasing the number of our service centers throughout Taiwan. We also offer comprehensive and high-quality point of sale and after sale services in our service centers, stores and over
the internet. Our extensive sales and distribution channels help us attract additional customers and develop new business opportunities. In 2012, we also obtained several domestic and international awards which recognized our service quality,
corporate governance and our fulfillment of corporate social responsibility. In the Readers Digest Trusted Brands Awards, we have stood out and won the Platinum Award of Telecom Company in Taiwan for nine consecutive years since 2004. We were
also awarded the Excellence in Corporate Social Responsibility Award by the Common Wealth Magazine, Excellent Service Award 2012 by Global Views, and were ranked A++in Transparency and Information Disclosure by the Taiwan Securities and Futures Institute.

Operational expertise. Our management and employees have extensive operating experience and technical knowledge, which
we believe cannot be easily replicated by competitors. We also believe we will continue to attract and retain high quality employees.

Comprehensive customer billing infrastructure. As Taiwans leading telecommunications services provider, we have extensive resources and infrastructure relating to billing services. We intend
to continue taking advantage of this unique attribute by offering bill collection services to internet content providers and other entities that lack the necessary resources and infrastructure for effective customer billing.

We have the capital resources and technology to enhance our leading position in the growing mobile
communications and internet services markets.

Enhancing position in our leading markets. We expect our mobile
value-added service, fixed broadband value-added and ICT services to continue to be the key drivers of our future growth. With our leading market share, we enjoy substantial economies of scale in equipment procurement as well as the marketing of our
products and services.

Strong capital structure. We believe we have great financial resources in Taiwan. Our low
debt-to-equity capital structure, together with our high levels of cash and operating cash flows, provides us with the flexibility and resources to invest in capital intensive and growing businesses. In particular, we continue to invest in broadband
internet protocol networks, fiber-optic networks, and 3G/HSPA, HSPA+, Dual cell HSPA+ mobile communications networks and services. We have also begun to make investments in or to acquire other companies which provide complementary
telecommunications and internet-related services to further expand our business and offer new products and services.

Advanced network technology. Since 2003, we have developed and upgraded our existing infrastructure for both mobile and fixed-line
networks. We developed a high-speed internet protocol backbone network, expanded the coverage of our ADSL network, and deployed a 3G network. In 2008, we launched a long-term next generation network construction project that will upgrade our local
fixed-line networks to high-speed packet-based digital networks with FTTx technologies, including FTTC/N, FTTB and FTTH, in order to provide high speed internet, VoIP, MOD and high definition television, or HDTV, services. We have also upgraded our
3G network to HSPA and HSPA+, and Dual cell HSPA+. In 2012, we expanded HSPA/HSPA+/Dual cell HSPA+ coverage to provide better mobile internet services. Our investment in network infrastructure places us in a position to capture a
significant share of the internet and high-speed data transmission market.

Research and development expertise. As of
March 31, 2013, we employ over 2,474 research professionals and engineers whose principal focus is to develop advanced network services and operations support systems and to build selected core technologies. In 2012, our research and
development expenses accounted for 1.7% of our revenues under ROC GAAP. We believe our focus on research and development will allow us to efficiently develop and deploy new technologies and services ahead of our competitors.

Business Strategy

Taiwan has one of the highest fixed-line penetration rates in Asia and has also experienced rapid adoption of wireless communications and
internet services, including broadband access services. We believe that telecommunications services will evolve over the coming years, driven by a number of technological innovations, including cloud computing, mobile value-added services and
Internet of Things. We also believe that the convergence trend of communications technologies will provide a significant competitive advantage to integrated telecommunications service providers that are able to design and construct sophisticated and
scalable networks capable of serving as a common platform for a broad range of services.

Our key strategic objectives are to
maintain our position as a leading integrated telecommunications services provider in Taiwan and to enhance our leadership position in growing markets, such as the mobile services and internet services markets, including fixed-line and mobile
broadband access services and value-added services. By leveraging on our solid and quality customer base, expanded network capacity and enhanced network capability, we plan to further enhance our fixed and mobile value-added services, or VAS,
offerings and promotion. We have also introduced new ICT services as well as cloud computing services by leveraging enterprise high speed broadband demand to offer VAS and explore emerging service.

Consistent with our strategic objectives, we have developed the following business
strategies:

Focus on our core strengths while maintaining our market share

Our core strengths are the management of telecommunication networks and the provision of services over these networks. We currently
operate several networks linked by a core backbone infrastructure consisting of public switched telephone, cellular, ADSL, FTTx and internet protocol networks. Our strategy for each network differs depending on the market dynamics and future growth
prospects of services delivered over these networks. In general, we endeavor to maintain our strong market position in each of our business lines and seek to expand the scope of our business beyond network services by offering value-added services
to generate growth and new opportunities.

Fixed communications: Our strategy is to maintain our position as the market
leader in domestic fixed communications. We aggressively introduced new technology and equipment of fixed network to improve operational efficiency and facilitate business transformation. In the meantime, we also provide MOD, cloud-based
multi-screen services and internet of things services including Intelligent Energy Network, or iEN, street surveillance services to improve customers digital life. We expect that these initiatives will enhance customers loyalty and
generate more revenues.

Broadband services: We strive to maintain our broadband market share. Therefore, we are
continuing the build-out of our FTTx infrastructure. We expect that we will be able to offer broadband services with speeds of 100 Mbps to 85% of households in the ROC by the end of 2013, including coverage of FTTH reaching 50% of households in the
ROC. As more customers within our current coverage area subscribe for 100 Mbps broadband services or FTTH services, we will still need to incur additional capital expenditures to deploy such services from the cross-connection boxes to each
customers premises. In addition, we plan to incur additional capital expenditures to further construct our FTTH infrastructure to expand our coverage area throughout the ROC. We believe these efforts will help us maintain our competitive
advantage for broadband services. A high quality broadband network is also essential for our high-definition MOD services.



| |  |  | We provide ADSL and FTTx services to 4.6 million customers, which represented more than 79.2% of Taiwans fixed-line broadband customers by
the end of 2012. Approximately 59.7% of our broadband customers were using FTTx services as of December 31, 2012.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We typically realize higher average revenue per user for our FTTx internet services, and we continue to offer various incentives for our ADSL and other
internet customers to upgrade to our FTTx services. In 2012, FTTx revenue reached 75.6% of our total broadband revenue.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Mobile Communications: We offer our mobile services via both 2G and 3G networks. For 3G, wideband code division multiple access, or WCDMA, is adopted. In order to meet the demand from our customers
for high-speed mobile data access, we upgraded our 3G mobile service to High-Speed Packet Access, or HSPA technology on September 12, 2006 and to HSPA+ services in 2010. The prevalence of smart devices, such as smart phones and tablet PCs
that utilize large amounts of mobile data, has become a challenging task for all mobile operators. We are continuing to develop Heterogeneous Network, or HetNet, to meet such demand. HetNet incorporates macrocells for large area coverage, and small
cells including micro cells, pico cells, femtocells and Wi-Fi to increase our data capacity. Our strategy for mobile service includes the following initiatives:



| |  |  | Further introducing mid- to low-tier smartphones to expand our mobile internet subscriber base;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | Promoting the migration of 2G customers to 3G network by offering various mobile handsets combined with attractive value-added services and product
packages;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expanding our HSPA+/Dual cell HSPA+ coverage and enhancing the base station bandwidth to attract more mobile internet customers;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | Constructing more Wi-Fi hotspots and hot zones to offer wireless internet access service and to offload 3G data traffic; in particular, we plan to
construct over 45,000 Wi-Fi Hotspots and 200 hot zones in metropolitan areas by the end of 2013;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | - |  | -------------------------------------------------------------------------------------------------

Internet services: Our strategy for internet services is to continue to build on the success of our HiNet internet services and
enhance our internet value-added services.



| |  |  | We are developing new media to provide both higher-speed access as well as attractive content to our customers. We are also continually enhancing our
internet value-added services, such as online games, internet music, internet banking and internet protocol video services, including hiChannel, an internet platform where customers can view videos and multimedia content.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Emerging services: Our emerging services include ICT, cloud computing and integrated services. We
have been providing ICT services since 2009, including iEN, and Intelligent Transportation System, or ITS, services. Our experience with ICT services positions us well to develop and offer cloud computing services, and we anticipate that cloud
computing services could become an important area of growth for telecom operators in the near future. We started to offer hicloud Compute as a Service, or CaaS and provide customers 24-hour installation services in 2010. We started to offer hicloud
Mall in 2011, which allows Independent Software Vendors, or ISV to offer their application software in the hicloud Mall for sale. In 2012, we also introduced cloud-based multi-screen services, named Hami+ providing music, video, news, e-book,
weather, traffic information, personal cloud and payment services. The integration of platform and network enables our customers to use and purchase the service through their PCs, IPTV, MOD, tablet PCs and smart phones, and satisfies users
needs to utilize those services anytime, anywhere with any device. For enterprise customers, we introduced hicloud Virtual Private Cloud, or VPC to facilitate the establishment of the dedicated cloud data center for centralized control of computing
resources, storage services, network services and information security total solutions. We also introduced the hicloud box to provide data storage and file sharing services, which helps enterprise customers reduce storage costs while providing a
platform to share resources in a protected environment. In 2012, our laboratory independently developed an open source cloud operating system under the Virtuoso brand name and cooperated with Wiwynn Corporation to provide cost effective
cloud appliances equipped with our open source cloud operating system. We are continuing to expand the scope and variety of our integrated services to create more value for our customers.

Emphasize quality of service and customer satisfaction

Quality of
service is critical in attracting and retaining customers and enhancing our long-term profitability. In order to continually enhance and improve the quality of our services, we have, in addition to the quality assurance function of our regular
operating units, established a number of dedicated task forces to monitor our network performance. Our senior management sets our quality evaluation criteria and regularly reviews the quality of our performance.

In order to ensure that our quality of service will translate into strong customer loyalty, we plan to continue to focus on and invest in
the provision of a full range of services that emphasize customer care from the point of sale onward. For example, we have extended the focus of our corporate customer services from major accounts to include small and medium-sized enterprises and in
January 2007 established our Enterprise Business Group. As of December 31, 2012, our Enterprise Business Group was staffed by 371 professionals and offered packaged and customized services, customer-oriented solutions and integrated information
and communications services. We have completed the integration of our call centers, all of which can now be reached by calling a single number 123. We offer 24-hour customer service, including the handling of service and billing
inquiries with the assistance of an Interactive Voice Response, or IVR, system. To improve the quality of our customer services, we implemented a customer relationship management system, which encompasses, among other things, a customer complaint
system, a business information database for the use of our call centers, and a data mining system to enhance our sales and market analysis efforts.

Improve operational efficiency and cost structure

We have historically been focused, and will continue to focus, on cost control, particularly in the areas of network efficiencies and
personnel costs. We expect to be able to further improve our operational efficiency and cost structure by migrating to more advanced networks and sophisticated operational support systems, and efficiently managing our workforce.

Capital expenditures. Our long-term goal is to optimize our capital expenditures by focusing on investing in innovative products
and services with attractive return profiles. To catch up with the fast evolution of digital devices and network applications, we continue the construction of our fiber-based fixed-line and mobile network to increase the network bandwidth and
enhance operational efficiencies. In particular, we plan to construct high capacity Wi-Fi/Fiber-Wireless networks to offload mobile network traffic and upgrade network equipment to improve operational efficiency and reduce operating cost. For
example, we have focused on redesigning optical distribution networks, consolidating aggregate networks, simplifying network layers, centralizing network planning and equipment procurement, designing Single Radio Access Networks, developing remote
automatic Operations, Administration, Maintenance and Provisioning systems and following precision construction policy to enhance equipment utilization rate and improve management efficiency.

Personnel costs. We seek to improve our operational efficiency by reducing our personnel costs. For example, we offered voluntary
retirement programs once each year since 2005, which resulted in reductions of 6,148 employees in total as of December 31, 2012. We also hired more than 3,953 new employees after our privatization in August 2005. Since then, we continued to
align our organizational structure by integrating various operating units and departments. We will also continue to reallocate our personnel from traditional fixed-line services to our growing businesses and to our marketing and customer services
departments, as well as exploring outsourcing opportunities where we deem appropriate. On January 30, 2013, we set up a human resource company, Honghwa Human Resources Co., Ltd., in order to save on personnel expenses as well as to provide
customers 24 hours a day, 7 days a week service installation and retail stores service.

Expand our business through
alliances, acquisitions and investments

We plan to expand our business in high-growth areas, such as interactive
multimedia broadband services, content delivery services and value-added services, through alliances, acquisitions and investments. We believe that our experience, operational scale and large customer base make us an attractive ally for other
service providers.

Alliances. We have formed and will continue to pursue alliances with information content providers,
multimedia service platform providers, customer premises equipment providers, internet portal operators, and information and communication technology solutions partners to diversify our business operations and enhance our service offerings. In
November 2012, we entered into a memorandum of understanding with Rhythm & Hues Studios, who has won the Academy Award for Best Special Effects twice and the Academys Scientific & Technical Award four times. We expect this
proposed alliance with Rhythm & Hues Studios to facilitate our ICT development. In January 2013, we signed a memorandum of understanding with Wiwynn Corporation. We aim to corporate with Wiwynn Corporation by combining its hardware solution
with our cloud technology to jointly provide customers plug-and-play appliance and explore domestic and overseas computing business opportunities. See B. Business OverviewMobile Communications BusinessMobile Services for a
discussion of our alliance on mobile services.

Acquisitions and Investments. We have focused our acquisition strategy
on making acquisitions of companies that we believe to be complementary to our long-term strategic goals. In addition, after our privatization, we have focused our investment strategy on the development of new businesses and the enhancement of our
operation efficiency. Recently we have entered into the following notable transactions:

In 2010, we acquired a 6.67% equity
interest in Innovation Works Limited, or IW. Our shareholding decreased to 1.92% in 2011 due to issuance of employee options. In June 2010, we invested 13.3% in Innovation Works Development Fund, or IWDF, which was established to support the
development of Innovation Works Limited. After IWDFs US$180 million capital increase in 2011, our shareholding in IWDF decreased to 4.4%. We believe our investment in IW and IWDF, which mainly conduct business operations or invest in the
mobile internet industry in mainland China, will help open up our business opportunities in e-commerce, mobile internet and cloud computing services in the mainland.

Maintain focus on maximizing stockholder value

We are committed to maximizing stockholder value and we intend to maintain our high dividend payout policy. Following our privatization,
we have more flexibility to implement capital management initiatives, including possible repurchases of our outstanding common shares and increases in our leverage through debt financing. We bought back 121,075,000 common shares between
August 29, 2007 and October 25, 2007 and cancelled those shares on December 29, 2007 and February 21, 2008, respectively.

We continued our capital reduction plan from 2007 to 2010. We effected the last capital reduction plan in 2010 by reducing 20% capital stock in the amount of NT$19.4 billion. The cash payment of NT$19.4
billion was made on January 25, 2011 to our stockholders.

B. Business Overview

Our Principal Lines of Business

Our core business segments are our domestic fixed communications business, mobile communications business, internet business and international fixed communications business.

Domestic Fixed Communications Business

The provision of domestic fixed communications services is one of our principal business activities. Our domestic fixed communications business includes local and domestic long distance telephone
services, broadband access services, local and domestic long distance leased line services, multimedia on demand services, and domestic other services including ICT, corporate solution services, cloud computing services, etc. We are the largest
provider of local and domestic long distance telephone services in Taiwan. We also provide interconnection with our fixed-line network to other mobile and fixed-line operators. Our revenues from domestic fixed communications services were NT$70.7
billion or 34.9% of our revenues in 2010, NT$79.4 billion or 36.5% of our revenues in 2011, and NT$75.5 billion (US$2,599.0 million) or 34.3% of our revenues in 2012. In general, we expect that revenues from our domestic fixed communications
business as a percentage of our total revenues will continue to decline primarily due to (i) the expansion of our mobile communications services and (ii) the general trend of a continued decline in fixed-line voice traffic. However, in
2011, our domestic fixed communications business increased as a percentage of our total revenues due to the change in pricing and collections policies for fixed-line-to-mobile phone calls. Starting on January 1, 2011, the fixed-line operators
now set and collect the tariffs for fixed-line-to-mobile phone calls, whereas prior to January 1, 2011, these functions were performed by the mobile operator. Please see Item 4. Information on the CompanyB. Business
OverviewRegulationInterconnection Arrangements. In 2012, the general trend returned, as our domestic fixed communications business declined as a percentage of our total revenues.

Local Telephone

The following table sets forth our revenues from local telephone services for the periods indicated.

telephone customers as of December 31, 2012 were residential customers. We are currently the leader of the local telephone service market, with an average market share of approximately 96.9%, 95.3% and 95.0% in 2010, 2011 and 2012,
respectively.

The following table sets forth information with respect to our local telephone customers and penetration rates
as of the dates indicated.

Demand for local customer lines has historically been driven by population growth. However, with the development of mobile technologies,
this trend has been declining. The number of fixed-line customers decreased by 2.4% in 2012 compared to 2011. We attribute the decrease in fixed-line customers to a general industry-wide trend of migrating from fixed-line services to mobile and
internet telephony services. In adherence to a ruling by the Supreme Administrative Court, starting from September 2011, we no longer require our ADSL service subscribers to apply for our fixed-line services. We also allow our existing ADSL
subscribers to unsubscribe their fixed-line service. The foregoing factors also caused the decrease in our fixed-line customers.

The following table sets forth information with respect to local telephone usage for the periods indicated.

|(2) | Calls to our HiNet internet service, which are recorded as part of our internet services, are not included in our local call minutes or revenues.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------

Minutes from local calls increased in 2011 due to the inclusion of minutes from fixed-line-to-mobile calls in
this category starting from 2011 as a result of the NCCs change in policy for collecting the tariffs of fixed-to-mobile phone calls by our fixed communications business. Minutes from local calls decreased in 2012 due to the impact of mobile
substitution and increased use of VoIP.

We charge our local telephone service customers a monthly fee and a usage fee. We
also charge separate fees for some value-added services. The monthly fees for our primary tariff plans are NT$70 with a deductible on usage fees of NT$25 for residential customers and NT$295 for business customers. Our primary peak time usage fee is
NT$1.6 for three minutes or NT$2.7 for ten minutes, depending on the tariff plan selected by the customer, and our off-peak usage fee is NT$1.0 for ten minutes. Our usage fees are the same for residential and business customers.

Average per minute usage charges increased from approximately NT$0.74 per minute in 2010 to approximately
NT$1.36 per minute in 2011 and further to approximately NT$1.41 per minute in 2012. The significant increase in average per minute usage charges in 2011 was mainly due to the change in policy for collecting the tariffs of fixed-to-mobile calls from
mobile service providers to fixed communications service providers since January 1, 2011, which granted our fixed communications business the right to set and collect the tariffs for fixed-line-to-mobile phone calls. Average per minute usage
charges increased 3.7% to NT$1.41 in 2012, and we attribute this increase to the fact that users with lower average tariffs switched to using VoIP telephony services to a greater extent than users with higher average tariffs. Part of our competitive
strategy is to offer customers innovative products and services intended to both secure customer loyalty and enhance revenues. In particular, our value-added services are designed to increase our call revenues by increasing the number of calls our
customers make and by receiving fees for usage of the value-added services. These services include call waiting, caller identification, call forwarding, three-party calls, ring back tone and voicemail.

Domestic Long Distance Telephone

We provide domestic long distance telephone services in Taiwan. Total revenues from domestic long distance telephone services were NT$6.6 billion representing 3.3% of our total revenues in 2010, NT$5.8
billion representing 2.7% of our total revenues in 2011, and NT$3.8 billion (US$0.1 billion) representing 1.7% of our total revenues in 2012. Our average market share in the domestic long distance market was approximately 76.1%, 74.1% and 75.4% in
2010, 2011 and 2012, respectively.

The following table sets forth information with respect to usage of our domestic long
distance telephone services, excluding operator trunk dialing, for the periods indicated.

Along with the mandatory tariff reduction for domestic long distance telephone services, the minutes of
use increased in 2012. See Item 5. Operating and Financial Review and ProspectsOverviewTariff adjustments. However, we expect the minutes of use for domestic long distance calls will continue to decline as a result of traffic
migration to mobile services and increased use of VoIP.

The following table sets forth information with respect to the

All domestic long distance calls, regardless of the distance between the calling parties,
have the same tariff. We reduced our peak hour domestic long distance rate in January 2012 from NT$0.032 per second to our current rate of NT$1.6 per three minutes. Our current domestic long distance rate for off-peak hours is NT$1.0 per three
minutes. Our average domestic long distance usage charge per minute decreased 41.2% in 2012 due to a further mandatory tariff reduction from the NCC. For more details of the NCCs mandatory tariff reduction, please see Item 5. Operating
and Financial Review and ProspectsOverviewTariff adjustments.

We provide so-called intelligent
network services over our domestic long distance network, including toll-free calling, personal number, televoting, premium rate service and VPNs. We also focus on offering our customers an increasing number of value-added services with flexible
tariff packages.

Broadband (ADSL+ and FTTx) Access

We provide broadband internet access through connections based on ADSL and our FTTx technology. FTTx generally offers a faster access medium for our internet customers compared to ADSL by using fiber
optic technology. We are continuing the build-out of our FTTx infrastructure. The majority of our FTTx deployments consist of fiber-to-the-node with some fiber-to-the-building deployments. The majority of the local loops still use copper wires, and
we do not have any present plans to upgrade the local loops to fiber optic lines. Because we typically realize higher average revenue per user for our FTTx internet services, we are offering various incentives for our ADSL and other internet
customers to switch to our FTTx services.

The following table sets forth our revenues from our broadband access services for
the periods indicated.

We provide broadband access services to other internet service providers that do not have their own
network infrastructure, and as a result, our broadband customers also include some customers that use only our broadband data access lines and choose another provider for internet service provider, or ISP, services. We began to provide our ADSL
service in August 1999 and had approximately 1.8 million customers as of December 31, 2012. As of December 31, 2012, approximately 71.9%, or 1.32 million, of our ADSL customers were also our HiNet subscribers. As a result of
increased migration to our higher-bandwidth FTTx services, the number of our ADSL customers continued to decline in 2012.

The
number of our FTTx customers increased significantly in 2010, 2011 and 2012 as prices became more affordable, coverage areas expanded and customer demand for higher bandwidth heightened. Many of new FTTx customers have migrated from using our ADSL
internet services. We also provide FTTx access services to other internet service providers that do not have their own network infrastructure, and as a result, our FTTx customers also include some customers who only use us for the FTTx data access
lines and choose another ISP to provide internet services. Of the approximately 2.72 million FTTx customers as of December 31, 2012, approximately 2.45 million were also our HiNet subscribers. We currently offer various promotional
packages to encourage more migration of our ADSL subscribers to our FTTx service. As of December 31, 2012, 65.0% of HiNet subscribers accessed the internet through our FTTx service, and we expect this ratio to increase in the future as a result
of these promotional measures.

Our market share of Taiwans broadband market was approximately 80.5%, 79.2% and 79.2% in
2010, 2011 and 2012, respectively.

Our ADSL service offers downlink speeds that range from 1 Mbps to 8 Mbps and uplink speeds that range
from 64 kilobits per second, or Kbps, to 640 Kbps. Our FTTx service offers downlink speeds of 12, 20, 50 and 100 Mbps matched with uplink speeds of 4, 5, 10 and 20 Mbps, respectively. As of December 31, 2012, approximately 88.7% of our
customers had subscribed for downlink speeds of over 12 Mbps, and our average downlink speed was 16.3 Mbps.

We have
experienced competition in the ADSL and FTTx service market from cable operators and other fixed-line operators. Our strategy is to continue the migration of ADSL subscribers to FTTx so as to increase the average revenue per user. In addition, in
order to strengthen customer loyalty, we have provided free speed upgrades for ADSL customers who were using lower speed services since August 2010. In June 2011, we further reduced our broadband tariff, especially for higher speed services such as
20 Mbps and 50 Mbps, in order to speed up the migration to fiber solutions and facilitate the take-up of relevant applications. Although the lower broadband tariff had a temporary impact on our revenue, we believe the speed upgrade will have a
positive effect on our promotion of broadband value-added services in the long run.

Charges for our HiNet dial-up service
include a monthly fee entitling the customer to a fixed number of minutes of service, with an additional charge per minute when the fixed number of minutes is exceeded. Alternatively, we offer our customers an unlimited number of minutes for a fixed
monthly fee. Charges for our ADSL and FTTx services include one-time installation charges and monthly subscription fees. These charges for our ADSL and FTTX services vary based on connection speed.

The following table sets forth our average revenue per user for each of the periods indicated.

The decline of our ADSL average revenue per user over the last three years was due to the NCCs mandatory tariff reduction and our
voluntary tariff reduction by 20% in the beginning of 2012. The decline of FTTx average revenue per user was due to the promotional packages and discounts provided for existing customers. For more details of the NCCs mandatory tariff
reduction, please see Item 5. Operating and Financial Review and ProspectsOverviewTariff adjustments.

Leased Line ServicesLocal and Domestic Long Distance

We are the leading provider of domestic leased line services in Taiwan. Leased line services involve offering exclusive lines that allow
point-to-point connection for voice and data traffic. Leased lines are used by business customers to assemble their own private networks and by telecommunications service providers to establish networks to offer telecommunications services.

We provide data transmission services to major corporate customers in Taiwan. We also provide leased lines to other mobile
and fixed-line service operators for interconnection with our fixed-line network and for connection within their networks.

The following table shows the bandwidth of local and domestic long distance lines leased to third parties as of each of the dates
indicated.



|                |  |                                   |         |  |      |  |         |      |  |  |         |

|                |  | 2010                              |         |  | 2011 |  |         | 2012 | 
|                |  | (in gigabits per second, or Gbps) |        
|Total bandwidth |  |                                   | 1,486.4 |  |      |  | 1,705.7 |      |  |  | 1,294.6 | 

Rental fees for local leased lines are generally based on transmission speed while domestic long distance
leased line rental fees are generally based on transmission speed and distance.

We continue to experience a decline in rental
fees for all of our leased line products. We attribute the general decline in rental fees since 2000 to a general migration toward broadband services and increased competition from other service providers constructing their own lines. In response,
we continue to implement marketing and service campaigns to retain our high-value corporate customers for our leased line products. Our local and domestic long distance leased line services revenues were NT$6.1 billion, NT$5.7 billion and NT$5.4
billion (US$0.2 billion) in 2010, 2011 and 2012, respectively.

Wi-Fi Services

We launched our wireless local area network service in May 2002. As of December 31, 2012, we had a total of approximately 1,280,315
residential and business customers that leased our access points. In addition, we had established 35,000 hot spots and 100 hot zones in public areas by the end of 2012, such as convenience stores, airports and international convention centers, where
our smartphone subscribers can access our Wi-Fi network and help to offload 3G data network traffic.

Multimedia on Demand Services

Using video streaming technology through a set top box that connects to our FTTx and ADSL data connections, our
customers can access TV programs, video-on-demand and other services. We had over 160 broadcasting channels and over 12,000 hours worth of on-demand programs and served approximately 1.2 million customers as of December 31, 2012. In
addition, our video-on-demand service provides movies, dramas, animations, documentaries, e-learning and music programs for home entertainment. Also, as of December 31, 2012, we offered 69 high definition, or HD, channels and other HD
video-on-demand programming, such as sports, movies and knowledge materials. Starting from the fourth quarter of 2012, we cooperated with Hon Hai Precision Industry Co., Ltd., or Hon Hai, to co-sell its sixty inches TV sets with our IPTV service by
bundling the two products together, which provides customers high-quality HD user experience. This effort is expected to further increase customer loyalty and attract quality customers, who are increasingly demanding more high-quality entertainment
options. Since this business model has proved to be successful, we will continue to cooperate with Hon Hai and other local TV manufacturers to co-market various sizes of TV sets with our quality MOD services. MOD revenues accounted for NT$1.1
billion, NT$1.4 billion and NT$2.0 billion (US$68.9 million) in 2010, 2011 and 2012, respectively.

Other Domestic Services

Our other domestic services include information and communication technology services, cloud computing, corporate solution and bill
handling services.

Mobile Communications Business

Mobile communications services are one of our principal business activities. Our mobile communications services include mobile services, sales of mobile handsets and data cards and mobile other services.

Mobile Services

We are Taiwans largest provider of mobile services in terms of both revenues and customers. In 2010, we generated revenues of NT$73.1 billion, or 36.1% of our total revenues, from mobile services.
In 2011, we generated revenues of NT$70.9 billion, or 32.6% of our total revenues, from mobile services. In 2012, we generated revenues of NT$72.5 billion (US$2,492.2 million), or 32.9% of our total revenues, from mobile services. The decrease of
mobile services revenues in 2011 was primarily due to the NCCs change in policy for collecting the tariffs for fixed-to-mobile calls from mobile service providers to fixed communications service providers since January 1, 2011. As a
result, our fixed communications business now has the right to set and collect the tariffs for fixed-line-to-mobile phone calls. However, the interconnection and transition fees paid by our fixed communication business and received by our mobile
segment is deemed as internal revenue and not recognized as external revenue of our mobile segment, while the aforementioned fees received by the alternative mobile operators were recognized as external revenue. In 2012, we managed to increase our
mobile revenue by promoting mobile internet services, which fully offset the decline of mobile voice revenue due to the NCCs mandatory tariff reduction and market competition.

|--- | ----------------------

As the
market for mobile services has continued to expand, we have experienced growth in our mobile customer base. We are the largest mobile operator in Taiwan in terms of revenues and number of customers. We had 10.3 million mobile customers, for a
market share of approximately 34.9% of total mobile customers and approximately 33.0% of total mobile services revenues in Taiwan, as of December 31, 2012.

In February 2002, the Ministry of Transportation and Communications granted 3G mobile services concessions to five companies, including us. In March 2002, we paid NT$10.2 billion to the government for our
concession. Our 3G mobile services license is valid until December 31, 2018. In July 2005, we launched our 3G mobile services, using WCDMA technology. We have been allocated 15 MHz paired spectrum plus 5 MHz unpaired spectrum in the 2 GHz
frequency band for 3G mobile services, and 15 MHz in the 900 MHz frequency band and 11.25 MHz in the 1800 MHz frequency band for GSM services and general packet-switched radio services, or GPRS. We offer the largest international roaming network
among Taiwan mobile service providers. By the end of 2012, our 3G roaming contracts includes 175 networks in 80 countries, our 2G GSM roaming contracts include 379 networks in 190 countries, and our 2.5G GPRS roaming contracts include 301 networks
in 139 countries.

As of December 31, 2012, we had 19,941 cellular base stations, including both GSM base stations and 3G
cellular base stations, covering substantially all of Taiwans population. We use these base stations to support both our GSM network and 3G networks. As of December 31, 2012, we had upgraded 10,384 3G cellular base stations with HSDPA
capacity, and 2,400 GSM base stations with EDGE capacity in the larger metropolises of Taiwan. We will continue this process of implementing HSDPA and EDGE upgrades in the major areas of Taiwan.

Total mobile customers in Taiwan had reached approximately 29 million as of December 31, 2012. Mobile penetration was approximately 126.2% on the same date. The overall mobile services market
experienced a slight increase of 1.01% in revenues in 2012 mainly due to the growth in mobile data service as a result of our smart phone promotions.

We began offering prepaid card services in October 2000 and prepaid 3G card services in February 2008. As of December 31, 2012, we had approximately 1.1 million prepaid customers, representing
approximately 10.9% of our total mobile customers. Prepaid customers do not pay monthly fees but pay a higher usage charge on a per second basis. Once the prepayment has been fully utilized, a prepaid customer can make additional prepayments to
continue the service. Alternatively, the customer may convert to become a post-paid customer while retaining the same telephone number.

We offer incentives, such as mobile handset subsidies, when new customers agree to sign a service contract with us or when existing customers renew their contracts with us ranging from 12 months to 30
months. We generally offer subsidies on mobile handsets equipped with more advanced data functions to promote the expansion of our 3G mobile services. Smart phones accounted for 69% of the total handsets we offered in 2012, and we expect the
percentage to reach more than 75% in 2013. We expect our average subsidy per handset in 2013 to decrease as we focus more on promoting mid-tier and low-tier smart phones. At the same time, we expect to maintain our mobile internet market leadership.

Our tariffs for post-paid mobile customers primarily consist of usage fees and monthly fees.
When our customers are outside Taiwan, they pay roaming charges plus international long distance charges and, where applicable, local charges in roaming destinations. We negotiated with Vodafone, the largest telecommunications service provider in
Europe, in November 2009 to join their global telecommunications alliance. As a result, we began offering our customers discounts on their roaming charges starting December 1, 2009. However, we expect our strategic alliance with Vodafone to be
terminated by the end of April 2013 after our current agreement expires, as Vodafone has already entered into another strategic alliance with one of our competitors. We are negotiating with other providers for strategic cooperation for our roaming
business, and we will continue cooperating with local operators in different countries. We also offer discounts on usage fees for calls made between our mobile customers to encourage subscription to our mobile service. Our 3G service provides a
monthly flat rate service to our customers using our 3G service for internet purposes.

Our average revenue per user per month
decreased from NT$598 in 2011 to NT$594 in 2012, mainly due to the NCCs mandatory tariff reduction. The strong promotion of our mobile internet services leads to the rapid growth in value-added service revenues and helps to cover for the
decline in mobile voice revenues. In order to alleviate the impact of the decline in average revenue per user, we intend to continue introducing new value-added services and promote our 3G and wireless internet services.

In addition to our basic mobile services, we also offer a broad range of value-added telecommunications and information services. In
August 2001, we introduced a platform of integrated mobile value-added services under the brand name emome. Our emome services offer a broad range of value-added services, including financial information, transaction
services, emergency services access numbers, directory information, time, weather and traffic reports. In addition, we launched other mobile value-added services, such as JAVA games, unstructured supplementary service data, mobile internet and
multimedia messaging services. After the launch of our 3G mobile services, we began providing video phone, video-on-demand and other related 3G mobile value-added services as well. In 2009, we successfully created a business model integrating smart
phones with customer-tailored services, promoted our mobile internet service business, created the Hami value-added service platform and led the industry in providing e-book service and Hami Apps service. In addition to creating
additional sources of revenues, we believe these services enhance customer loyalty and satisfaction and increase mobile traffic. Revenues from mobile data services represented 15.1%, 21.5% and 28.2% of our total mobile services revenues in 2010,
2011 and 2012, respectively.

Paging Services

Due to substitution by mobile services and a decline in demand for our paging services in recent years, beginning in February 2007, we started downsizing our paging services by limiting access to certain
telephone prefixes. We ceased providing paging services in September 2011 as approved by the NCC.

Sales of Mobile Handsets

We engage in the distribution and sales of mobile handsets for use on our mobile network to customers through our
directly-owned stores, our subsidiary, Senao International Co., Ltd., or Senao, and also through third-party retailers. See Marketing StrategyDistribution Channels and Sales and Distribution in Marketing,
Sales and Distribution.

In January 2007, we acquired 31.33% equity ownership of Senao, a major distributor of mobile
handsets in Taiwan. Senao has been listed on the TWSE under the number 2450 since May 2001. We obtained majority board representation in April 2007 through support from the largest beneficial shareholder, upon which it became a
consolidated subsidiary of ours. At the general annual stockholder meeting of Senao in June 2010, we continued to maintain control of a majority of the board of directors through the continued support of the largest beneficial shareholder. Our
equity ownership in Senao decreased from 31.33% as of January 15, 2007 to 28.24% as of March 31, 2013 due to the exercise of options by employees that were previously granted before 2007. Please refer to note 1 of our consolidated
financial statements included elsewhere in this annual report for description about the control relationship between the parent company and Senao. Our investment in Senao enhanced our mobile handset distribution and sales capabilities. See
Item 7. Major Stockholders and Related Party TransactionsB. Related Party Transactions for a discussion of the agreement between the parent company and Senao about our business cooperation.

Other Mobile Services

Our mobile other services include information and communication technology services, corporate solution and bill handling services.

Internet Business

Our internet business includes HiNet, our internet
service provider, internet value-added services, or VAS, data communication services, internet data center services, and other internet services. Our internet revenues represented 12.1%, 11.4% and 11.2% of our revenues in 2010, 2011 and 2012,
respectively.

HiNet Internet Service

We are the largest ISP in Taiwan, with a market share of 69.6% as of December 31, 2012. As of December 31, 2012, HiNet had approximately 4.2 million subscribers. Our HiNet internet service
generated revenues of NT$18.2 billion, NT$18.0 billion, and NT$17.0 billion (US$0.6 billion) in 2010, 2011 and 2012, respectively. Although our ISP service subscribers increased from 2010 to 2012, the revenues decreased mainly due to the tariff
reductions for the HiNet ISP service and broadband access.

The following table sets forth HiNets subscribers as of each
of the dates indicated.

We have maintained our leading market position despite a highly competitive market with over 205 ISPs in Taiwan. We expect the competitive conditions currently prevailing in the internet service provider
market to continue to intensify.

Internet Value-added Services

Our HiNet portal at www.hinet.net provides value-added services to our customers, such as network security, Blog, travel, games,
e-learning, financial information, music, video, anti-virus and links to other portals. We charge fees for some of these services. We also receive commissions for transactions completed on some of these other portals. Our internet video portal at
www.hichannel.hinet.net offers online entertainment services through the internet. In particular, our HiNet broadband (ADSL and FTTx) subscribers can access music, television programs, movies and other multimedia content on demand. We charge access
fees for some of this content. We expect the revenues generated from these value-added services to grow as a percentage of our total internet services revenues.

Data Communication Services and Internet Data Center Services

We provide a wide range of managed data services, including frame relay services, asynchronous transfer mode services, and VPN services.
Frame relay services provide high-speed data communications linking remote sites. Asynchronous transfer mode services are used to handle high-bandwidth, integrated voice, video, data and internet traffic between sites.

Internet data centers are facilities providing the physical environment necessary to keep computer network servers running at all times.
These facilities are custom-designed with high-volume air conditioning temperature control systems, secure access, reliable electricity supply and connections to high-bandwidth internet networks. Data centers house, protect and maintain network
server computers that store and deliver internet and other network content, such as web pages, applications and data. We currently have the greatest number of internet data centers in Taiwan compared to our competitors in Taiwan. We offer
co-location, web hosting and application service provider services.

Other Internet Services

Our other internet services include government services, corporate solution and ICT services.

International Fixed Communications Business

Our international fixed communications business include international long distance telephone services, international leased line services, international data services, satellite services and
international other services.

International Long Distance Telephone

We provide international long distance telephone services in Taiwan. Total revenues from international long distance telephone services
comprised 6.4%, 5.7% and 5.5% of our revenues in 2010, 2011 and 2012, respectively. In addition, we provide wholesale international long distance services to international simple resale operators that do not possess their own telephone network or
infrastructure.

Since international fixed communication services have been open for competition since 2001, we expect
competition in this line of business will continue to intensify. Our average market share of the international long distance market was approximately 58.4%, 54.9% and 51.0% in 2010, 2011 and 2012, respectively. Our market share decreased in 2012
primarily because of the intense competition in the international telecommunications business from VoIP-based international long distance service providers and other international long distance service providers. Our international long distance
services consist primarily of international direct dial services.

We commenced the wholesale of international long distance
minutes to licensed international resale operators and other international carriers in 2001. International resale operators require a fixed-line operator in Taiwan to complete their long distance telephone services originating in Taiwan. In
addition, other international carriers often find it less expensive to route international calls through Taiwan. These resale operators and carriers purchase from us large numbers of minutes at discounted rates. In 2010, 2011 and 2012, we sold
1,360 million, 1,206 million and 1,064 million of wholesale outgoing minutes, which represented approximately 50.1%, 47.1% and 42.2% of our total outgoing international long distance minutes, respectively. Revenues from the wholesale
of international long distance minutes increased by 3.2% from NT$2,836 million in 2010 to NT$2,927 million in 2011, and decreased 0.48% to NT$2,913 million in 2012. We primarily attributed the decrease in the growth rate to intensified market
competition.

International calls to our top five destinations represented 63.0% of our outgoing international long distance
call traffic in 2012. International calls from our top five destinations represented 42.0% of our incoming international long distance call traffic in 2012.

Total outgoing international long distance minutes decreased 5.7% from 2010 to 2011 primarily due to an
increase in our international long distance wholesale and transit businesses. Our outgoing call volume decreased by 1.4% from 2011 to 2012 primarily due to intensified market competition from VoIP-based international long distance service providers
and other international long distance service providers. Our incoming call volume decreased by 9.3% from 2010 to 2011, and further decreased by 11.9% from 2011 to 2012 primarily due to the competition mentioned above.

Outgoing calls made by customers in Taiwan and by customers from foreign destinations using Taiwan direct service are billed in
accordance with our international long distance rate schedule for the destination called.

Rates vary depending on the time of
day at which a call is placed. Customers are billed on a six-second unit basis for international direct dial services.

The
following table sets forth information with respect to the average international long distance usage charge per minute that we received for outgoing international calls during the periods indicated.

The average charge per minute increased in 2011 compared with that in 2010 because we ceased
to offer aggressive discounts and the decrease in the international long distance revenues was relatively smaller than the decrease in the number of minutes. In 2012, since other operators offered competitive tariff to grab market share, we reduced
our retail price to maintain competitiveness which resulted in the lower average charge per minute.

We pay for the use of
networks of carriers in foreign destinations for outgoing international calls and receive payments from foreign carriers for the use of our network for incoming international calls. Traditionally, these payments have been made pursuant to settlement
arrangements under the general auspices of the International Telecommunications Union. Settlement payments are generally denominated in U.S. dollars and are made on a net basis.

The following table sets forth information with respect to our gross international settlement receipts and payments during the periods
indicated.

Our payments to international carriers on an aggregate basis have been greater than our receipts from
these carriers primarily because our customers outgoing minutes exceeded incoming minutes. Both international settlement receipts and payments increased in 2012 because we promoted our international wholesale business.

In order to compete more effectively in the international long distance market, we have implemented innovative and customized discount
calling plans and marketing campaigns directed at high-usage business customers. We also continue to promote our intelligent network services, including international VPNs, international toll free calling and calling card services, and our
international long distance minutes wholesale business. Our subsidiary, Chief Telecom, launched its 070 phone-to-phone VoIP service in April 2009. In addition to the change in policy for collecting the tariffs for fixed-line-to-mobile calls starting
from 2011, we are also required to pay transition fees to the mobile operators, which as a whole caused a negative impact on our revenues. As we did not have the right to set and collect the tariffs for our 070 service at that time, we filed with
NCC to return 30 thousand 070 numbers assigned by the NCC to Chunghwa Telecom, until the NCC gives us the right to set and collect the tariffs for outbound calls from 070 numbers. The application was approved by the NCC on July 1, 2011.

Leased Line ServicesInternational

We are a leading provider of international leased line services in Taiwan. Leased line services involve offering exclusive lines that allow point-to-point connection for voice and data traffic. Leased
lines are used by business customers to assemble their own private networks and by telecommunications service providers to establish networks to offer telecommunications services.

We provide data transmission services to major corporate customers in Taiwan. Since August 2001, licenses have been awarded to four
undersea cable operators to engage in leased line services. Demand for high-speed data transmission services has been growing rapidly, as a result of growing consumer demand and lower tariffs due to increased competition. In particular, the total
bandwidth of our lines leased increased by 118% in 2012.

The following table shows the bandwidth of international lines
leased to third parties as of each of the dates indicated.

Rental fees for international long distance leased lines are generally based on transmission
speed and distance.

We continue to experience a decline in rental fees for all of our leased line products. The decline in
rental fees since 2000 has been substantial, particularly for international leased lines, partly as a result of competition from new international leased line service providers. In response, we continue to implement marketing and service campaigns
to retain our high-value corporate customers. Our international leased line services revenues were NT$1.0 billion, NT$1.0 billion and NT$1.2 billion (US$41.3 million) in 2010, 2011 and 2012, respectively.

International Data Services

Our international data services include international IP VPN services and Taiwan internet gateway services. Total revenues for international data services were NT$1.0 billion, NT$1.1 billion, and NT$1.3
billion (US$44.8 million) for 2010, 2011 and 2012, respectively. Due to growth of the international corporations in Taiwan, we expect demand for IP VPN and Taiwan internet gateway services to continue to increase and our revenues from our
international data services to continue to grow.

Satellite Services

We entered into a contract with ST-2 Satellite Ventures Pte., Ltd. on March 12, 2010 to lease capacity on the ST-2 satellite. The
lease term is 15 years starting from the official start of operations of the ST-2 satellite, and the total contract value is approximately NT$6.0 billion. This contract requires a prepayment of NT $3.1 billion, and the remaining amount will be paid
annually when ST-2 satellite starts its official operation. The ST-2 telecommunications satellite launched on May 21, 2011 and began commercial operation in August 2011. Please refer to note 28 of our consolidated financial statements included
elsewhere in this annual report for further details.

In addition, we have two satellite communication centers that enable us
to provide satellite value-added services and backup systems for use in major emergencies. We also provide satellite services to Southeast Asia.

Other International Services

Our other international services
include corporate solution services.

Others

Our other business segments include our non-telecom services, including property sales made by our subsidiary, Light Era Development Co., Ltd.

Interconnection

We provide interconnection of our fixed-line network and
mobile network with other operators.

The following table sets forth our interconnection revenues and costs for the periods
indicated. These revenues and costs are included, depending on the nature of the call made, in domestic fixed communications or mobile communications revenues and expenses, respectively.

|(3) | The interconnection costs increased in 2011 due to the change in the policy for collecting the tariffs for fixed-line-to-mobile calls starting from 2011, and decreased
in 2012 due to the decrease in the traffic of fixed-line-to-mobile calls.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Tariffs for telephone calls between
our fixed-line customers and mobile customers of other mobile operators were set by the mobile operators before January 1, 2011. The mobile operators pay us interconnection fees based on minutes of use, regardless of who initiated the call.
However, the NCC announced a change on August 4, 2010 that from January 1, 2011 onwards, the fixed-line network that initiated the call has the right to set and collect the tariffs for these fixed-line-to-mobile calls. Since we are the
market leader of the local call services, in addition to the interconnection fees, we are also required to pay transition fees to the mobile operators for a period of six years. The transition fees will decrease gradually over the period and we will
stop paying for them in 2017.The foregoing reasons caused the increase in our interconnection costs in 2011. In 2012, both interconnection revenues and costs decreased due to the decrease in both incoming and outgoing minutes.

The interconnection rate for calls initiated by mobile customers to fixed-line customers is NT$0.5219 per minute during peak times and
NT$0.2718 per minute during off-peak times. The interconnection rate between fixed-line customers and other fixed-line customers is NT$0.32 per minute during peak times and NT$0.09 per minute during off-peak times. The interconnection rate for
fixed-line customers to domestic or international long distance is NT$0.32 per minute. Additionally, the NCC has mandated mobile interconnection rate reduction over a period of four years starting on January 5, 2013. The rate should be reduced
from NT$2.15 per minute to NT$1.15 per minute in four years with a CAGR of -14.5% .

In accordance with governmental
regulations, the contracts governing our interconnection arrangements must specifically address a number of prescribed issues. For example, our interconnection charge should reflect our costs with respect to the network elements used. In addition,
cost increases are subject to approval by the regulatory authorities. We expect that our interconnection contracts will generally be reviewed annually, although we may also enter into long-term contracts.

Emerging Services

Our
ICT services includes integrated services such as our Intelligent Energy Network, or iEN, and our Intelligent Transportation System, or ITS, services. Our iEN service helps companies and corporations implement energy saving measures through computer
analysis of data. Our ITS service provides navigation, real-time traffic information and infotainment through mobile devices for cars and drivers. In addition to developing ICT businesses, such as iEN, ITS, IS, Call Center, IDC, we also pursue and
bid for government projects aiming to boost economic development. In 2012, we won the bids for several government projects, such as New Taipei City Police Department Digital Video Surveillance System and TWSE Corporation Second
Data Center.

Cloud Computing is also one of our key new business initiatives, as it is expected to be one of the main
long-term growth platforms for telecom operators in the coming years. We have made advances in this segment throughout 2012 which we believe will position us as an industry leader over the long run. We continue to cooperate with the government
network communication entities and independent software vendors to promote innovative cloud services and applications. We have already begun to offer Software as a Service Customer relationship management, or SaaS CRM, hicloud CaaS, and hicloud Apps
mall to small and medium sized enterprises and public users. We have also made over 700 SaaS in hicloud Apps mall, and the number of our cloud customers exceeded 2,000 small and medium sized enterprises as of the December 31, 2012. Underpinning
the rollout of our cloud computing services is our capability and experience in offering data center services to enterprise customers, including our ongoing initiative to build the largest cloud computing data center in Taiwan in anticipation of
growing demand for this service. In 2012, we won the bids for some government projects, such as The Third Generation Motor Vehicle & Driver Information System, The Cloud Data Center of the Executive Yuan and Subordinate
Commission and National Fire AgencyThe Cloud Plan of Disaster Prevention and MitigationThe Establishment of Infrastructure Service Platform, Operational Management and Message Service Platform. We believe the strength
and reliability of our technology and services provide us with competitive advantages to continue expanding our cloud computing services in the future.

Marketing, Sales and Distribution

Marketing Strategy

In order to retain and expand our large customer base and to encourage our customers to increase their use of our services and products,
we continue to focus our marketing strategy on the following areas.



| |  |  | Services, Products and Bundled Offerings. We continually develop new value-added services and products, and bundle our services and products based on
different market segments, with the aim of increasing our high-usage customers and enhancing customer loyalty. For example, we entered into an agreement with Apple Inc. and are currently a reseller of the iPhone in Taiwan. The iPhone combined with
our mPro service helps retain existing customers and generate revenues through the increased use of our value-added services. In addition, we exempt deposits that we collect from specific mobile subscribers in advance for bundling subsidized mobile
handsets with service plans.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Pricing and Promotions. We design flexible pricing packages that allow customers to select structures best tailored to their usage patterns, and design
special promotional packages to encourage usage. For example, we have provided Lets Talk, My Hotline and Triple Save promotion packages to attract mobile customers.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Distribution Channels. We seek to facilitate customer subscription by adding more service points. In addition, we seek to broaden our distribution
reach by strengthening our cross-industry alliances and marketing relationships. Furthermore, we seek to expand our sales channels by implementation of a sales agent system. In 2009, we began a collaboration with Tsann Kuen Trans-Nation Group,
allowing the registration of mobile numbers at electronics stores for the first time, effectively increasing our points of sale. We also developed staff incentive programs to better motivate our sales staff.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Business Customers. We expanded our customer focus to include small and medium-sized enterprises in addition to large corporations. We seek to serve
the needs of large corporate customers by devoting a project manager or project engineer to service these customers. These account managers are responsible for developing customized solutions and tariff packages to meet the specific needs of our
customers. We continually update and expand our service offerings so that we can remain a one-stop telecommunications services provider to our corporate customers and provide for all of their telecommunications needs. Our dedicated local teams serve
the needs of small and medium-sized enterprises. These teams also use our data bank to identify and target potential clients for promoting our e-commerce and mobile services. In addition, we help our corporate customers improve their efficiency and
competitiveness by creating information systems for them.

Synchronous digital hierarchy, or SDH, architecture is an advanced technology that allows
for instantaneous rerouting and eliminates downtime in the event of a fiber cut. In addition, SDH offers better reliability and performance for optical fiber transmissions at a lower operating cost. In December 2002, we installed synchronous
transport module 64 or STM 64, multiplexer and 32-wavelength dense wavelength division multiplexing, or DWDM, equipment on our long-haul backbone network. Our STM 64 multiplexer can multiplex several low speed signals into a 10 gigabits per second,
or Gbps, high-speed signal. DWDM equipment uses a technology that puts data from different sources together on an optical fiber with each signal carried on its own separate wavelength. Both STM 64 multiplexer and DWDM equipment can increase our
network capacity. Between 2007 and 2012, we deployed 40/80-wavelength Re-configurable Optical Add-Drop Multiplexer, or ROADM, for backbone transmission network in order to provide new data services such as gigabit Ethernet, fiber channel, 2.5
gigabit and 10 gigabit packet over SDH and 10 gigabit Ethernet. We have already completed the deployment of 892 wavelength ROADM by the end of 2012. To meet the demand for broadband services, we will install an optical cross-connect, or OXC, network
and a next generation synchronous digital hierarchy, or NG SDH, network, which provides gigabit Ethernet over SDH service, between 2009 and 2013. We have already completed the deployment of 4,385 GbE OXC/NG SDH by the end of 2012.

Based on the transmission network described above, we have been providing connection circuit service of 10 gigabit packet over SDH and 10
gigabit Ethernet to the governments Taiwan Advanced Research and Education Network since November 2006 and will continue the service until November 2013.

As part of our strategic focus on the internet and data markets, our local loop connections use ADSL technology. This enables us to deliver high-speed internet, multimedia and other data services to our
customers. Substantially all of our installed telephone lines are capable of delivering ADSL services. As of December 31, 2012, we had approximately 3.87 million lines of ADSL and had 1.8 million ADSL customers. In addition, the
Ethernet-based FTTx system is also introduced into our access network to provide broadband services, such as MOD, high speed internet access and VPN. As of December 31, 2012, we have constructed approximately 4.75 million FTTx ports and
had 2.7 million FTTx customers. Our FTTx service can offer high-speed broadband internet access rates up to 1Gbps.

Switching
Networks

Domestic telecommunications network. Our domestic public switched telephone network currently consists
of 19 message areas connected by a long distance network. As of December 31, 2012, we had 38 long distance exchanges, which are interconnection points between our telecommunications network and approximately 17.5 million telephone lines,
which reached virtually all homes and businesses in Taiwan.

We currently have intelligent networks installed over our public
switched telephone networks for our domestic long distance and international networks, as well as a local intelligent network in the Taipei, Taichung and Kaohsiung metropolitan areas. Our intelligent network is designed to facilitate the use of
value-added services by providing more information about calls and allowing greater management of those calls.

As of
December 31, 2012, our NGN core network consisted of 985,500 local telephone subscribers, comprising 448,000 Session Initiation Protocol-based, or SIP-based, and 537,500 Access Gateway-based, or AG-based, subscribers.

Our NGN Managed IP backbone network consists of an inner core network and an outer core network. We completed the construction of our
high-speed NGN Managed IP backbone network at the end of 2012 with 12 sets of 1.6 Tbps/640 Gbps switch routers for the inner core network and more than 26 sets of 1.6 Tbps/640 Gbps switch routers for the outer core network. The bandwidth of the
network is approximately 755 Gbps as of the end of 2012. We believe this network will enable us to meet the increasing demand for NGN services, such as VoIP, and all managed services, including MOD and VPN.

International network. Our international transmission infrastructure consists of both submarine cable and satellite transmission
systems, which link our national network directly to 100 telecommunications service providers in 43 international destinations.

We provide mobile services based on the GSM network standards. We have the 900 MHz and 1800
MHz frequency bands paired with spectrums of 15 MHz and 11.25 MHz, respectively, for our GSM services. As of December 31, 2012, we had constructed 9,557 base stations, providing up to 99.9% population coverage. Since the launch of our 3G mobile
services, we have gradually transitioned GSM subscribers to 3G and have started to consolidate our GSM network.

We have
installed an intelligent network on our mobile services network infrastructure to enable us to provide prepaid services as well as a wide range of advanced call features and value-added services. As of the end of 2012, our intelligent network
capacity reached 1.12 million prepaid customers and 1.01 million mobile virtual private network customers.

We have
15 MHz paired spectrum plus 5 MHz unpaired spectrum in the 2 GHz frequency band for our 3G mobile services, which was launched in July 2005. We contracted with Nokia Siemens Networks to provide the core network, radio access network, service
network, transmission network and maintenance network for our 3G network. To promote mobile internet use, we upgraded our network to 3.5G in September 2006, with downlink and uplink speeds of 7.2 Mbps and 2.0 Mbps, respectively. To meet the high
growth in mobile data traffic, we have upgraded our existing High-Speed Packet Access (HSPA with capability of 14.4 Mbps and 5.76 Mbps each for Down-link and Up-link) Network to HSPA+ (with capability of 21.6 Mbps and 11.5 Mbps each for
Down-link and Up-link). As of December 31, 2012, we had completed the construction of about 10,384 3G base stations with 6.7 million subscribers.

In order to operate our packet-switched network more efficiently, we have consolidated GSM and 3G serving GPRS support nodes (SGSN) into a single core network. We have also introduced the Direct Tunnel
technology to flatten the packet-switched network to enhance the users experience.

Internet Network

HiNet, our internet service provider, has the largest internet access network in Taiwan, with 33 points of presence approximately
5,572,000 broadband remote access server ports and a backbone bandwidth of approximately 2,310 Gbps as of December 31, 2012. We plan to increase HiNets points of presence and backbone bandwidth to approximately 3,100 Gbps by the end of
2013.

HiNets broadband backbone network consists of an inner core network and an outer core network. We completed the
construction of our high-speed internet protocol backbone network at the end of 2012 with 16 sets of 7.04Tbps/4.48Tbps/1.6Tbps/1.28Tbps switch routers for the inner core network and more than 50 sets of
2.64Tbps/1.6Tbps/1.28Tbps/880Gbps/640Gbps/320Gbps switch routers for the outer core network. We believe this network will enable us to meet the increasing demand for our internet services.

HiNets total international connection bandwidth is 423 Gbps as of December 31, 2012. As we expect that internet traffic flows
to and from the United States will continue to increase, we plan to expand our bandwidth to the United States. We also plan to increase our links to other countries, including Japan, Korea, Hong Kong, Singapore, Mainland China, Malaysia and
Thailand.

Leased Line and Data Switching Networks

We operate leased line networks on both a managed and unmanaged basis. In addition, we operate a number of switched digital networks used principally for the provision of packet-switched, frame relay,
asynchronous transfer mode technology and a multi-protocol label switching internet protocol VPN. We have completed the construction of a digital cross connect system for provisioning and managing voice-grade data services throughout Taiwan with a
total of 50 nodes. As of December 31, 2012, we had 1,088 frame relay ports, 1,819 asynchronous transfer mode ports and approximately 72,334 multi-protocol label switching internet protocol VPN virtual ports.

Our data networks support a variety of transmission technologies, including frame relay, asynchronous transfer mode and ethernet
technology. We have also built up our HiLink VPN that combines internet protocol and asynchronous transfer mode technologies. The advantage of HiLink VPN based on multi-protocol label switching technology is that it can carry different classes of
services, such as video, voice and data together to provide services with various qualities of service, high performance transmission and fast forward solution in an enhanced security network. HiLink VPN can be accessed by ADSL/FTTx/NG-SDH and can
include built-in mechanisms that can deal with overlapping internet protocol addresses. Therefore, the network potentially is less costly and requires less management for business applications.

Competition

We face competition in virtually all aspects of our business.

Domestic Fixed
Communications

We were the largest domestic fixed communications service provider in Taiwan, with a market share of
approximately 95.0% in terms of customers for local telephone services, approximately 75.4% in terms of traffic for domestic long distance telephone services, and approximately 79.2% share of the broadband internet access market in terms of
customers in 2012, respectively. Three providers, namely, Taiwan Fixed Network, New Century Infocomm Tech. Co., Ltd. and Asia Pacific Telecom Co. Ltd., have provided fixed communication services since June 2001. Our domestic long distance services
compete with mobile services as people increasingly use mobile handsets. We believe that the fixed-line competition in Taiwan will be primarily based on price, quality of service, network coverage and customer services, such as call centers and
unified billing.

We are required by Republic of China regulations to provide number portability and unbundled local loop
access.

Our primary competitors in leased line services and broadband services include:



| |  |  | Leased line service providers: Taiwan Fixed Network, New Century Infocomm Tech. Co., Ltd., Asia Pacific Telecom Co. Ltd., East Asia Netcom Taiwan,
Reach Global Services Ltd., FLAG Telecom and Taiwan International Gateway Corporation.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Infrastructure Technology Co., Ltd.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Mobile Communications

There are currently three major GSM mobile operators in Taiwan, namely, Taiwan Mobile Co., Ltd., FarEasTone Telecommunications Co., Ltd.
and us. Based on data provided by the NCC, as of December 31, 2012, we were the largest mobile operator in Taiwan, with a 59.5% market share in terms of 2G customers. Smart phones with 3G mobile data packages are becoming popular in recent
years. To attract more high-end data users, all three major operators offer free intra-network calling packages bundled with mobile data service. Also, there are two 3G mobile operators in Taiwan in addition to us, namely Asia Pacific Telecom Co.,
Ltd. and Vibo Telecom Inc., as well as one personal handyphone system operator, First International Telecom. Furthermore, the government issued a total of 16 mobile virtual network operator, or MVNO, licenses, which allow operators without a
spectrum allocation to provide mobile services by leasing the capacity and facilities of a mobile service network from a licensed mobile service provider. We are currently cooperating with Carrefour Telecom Co., Ltd. We may cooperate with other
mobile virtual network operators in the future. As of the end of 2012, there were also six WiMAX service providers in Taiwan, providing services to approximately 137,009 customers in total according to the data provided by the NCC. We compete in the
wireless services market primarily on the basis of price, quality of service, network reliability and attractiveness of service packages.

Internet

Our primary competitors in internet services are other internet services providers, including SeedNet, TWM Broadband.

We are the largest provider of internet services in Taiwan. As of December 31, 2012, we had a 69.6% share of the Taiwanese internet service market in terms of customers. We compete in the internet
services market primarily on the basis of price, technology, speed of transmission, amount of bandwidth available for use, network coverage and value-added services.

International Fixed Communications

We are the largest international
fixed communications service provider in Taiwan, with a market share of approximately 51.0% in terms of traffic for international long distance telephone services in 2012. Three new providers, namely, Taiwan Fixed Network, New Century Infocomm Tech.
Co., Ltd. and Asia Pacific Telecom Co. Ltd., have provided fixed-line services since June 2001. We believe these operators are primarily focused on international long distance services. In addition, we anticipate that these operators will focus on
corporate customers, which typically generate higher profit margins than residential customers. Since August 2001, four undersea cable services licenses have been granted. These undersea cable operators, as well as internet service providers and
international simple resale operators, have begun offering international leased line services to other fixed-line operators, internet service providers and international simple resale operators.

Our international long distance services compete with international long distance resale services and alternative mediums for making
international calls, including VoIP technologies, such as those provided by Skype.

Cyber Security and Personal Information Protection

To prevent increasing cyber risks and threats, recently we have implemented the following mechanisms:



| |  |  | We have built an online service system which enables Certificate Authoritys Secure Socket Layer functions that performs as a secure tunnel to
transmit encrypted customers information. In addition, we offered the Global Trust Secure Site Seal to protect from phishing attacks on payment web sites.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The High-Availability systems in our data centers deploy firewall and Intrusion Prevention System, or IPS, to defend against hackers attacks, and
the web application programs enforce penetration test to ensure the security of our customers information.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The network equipment in our data centers could distinguish DDoS threats and reject or block the attacks. In the future, we could even block the DDoS
traffic over the backbone network.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

On May 26, 2010, the President of the Republic of China announced
the amendment of the Personal Information Protection Act, or PIPA, which became fully effective on October 1, 2012, except for its Articles 6 and 54 that await further determination by the Executive Yuan. PIPA applies to all individuals, legal
entities and enterprises that collect, process and use personal information, and has a significant impact on the banking and service industries in Taiwan. Due to the adoption of PIPA, the level of responsibility and liability on personal information

Properties

Our properties consist mainly of land, land improvements and buildings located throughout Taiwan. We own approximately 411 hectares of
land and 3.5 million square meters of building floor space. In January 2008, we established Light Era Development Co., Ltd. for the purpose of developing our real estate properties. As of December 31, 2012, we have transferred six
properties to Light Era Development Co., Ltd. The development work on five of these properties is completed. Light Era Development Co., Ltd. further acquired land located near the high speed rail station in Taoyuan, from a private party in October
2012. This property will be used to develop smart residential buildings. We plan to deploy state-of-the-art technologies including fiber broadband, ICT services, energy saving technologies and remote surveillance service technologies in these
intelligent residential buildings. Following the gradual completion of land rezoning, we have focused our real estate development more towards multiuse and diverse projects. Hence, we have developed more properties for commercial use
and participated in government urban redevelopment plans. We have received approximately NT$608 million (US$20.9 million) in rental income in 2012 from such properties.

Insurance

We do not carry comprehensive insurance for our properties or
any insurance for business disruptions. We do, however, maintain in-transit insurance for key materials, such as cables, equipment and equipment components. We do not carry insurance for the ST-2 satellite since we only lease capacity for our
operations instead of owning the satellite.

Employees

Please refer to Item 6. Directors, Senior Management and EmployeesD. Employees for a discussion of our employees.

Our Pension Plans

Currently, we offer two types of employee retirement
plansour defined contributions plan and defined benefits planwhich are administered in accordance with the Republic of China Labor Standards Act and the Republic of China Labor Pension Act.

Legal Proceedings

A
portion of the land used by us during the period between July 1, 1996 and December 31, 2004 was jointly owned by us and Chunghwa Post Co., Ltd., Directorate General of Postal Service. In accordance with the claims process in Taiwan, on
July 12, 2005, the Taiwan Taipei District Court sent a claim notice to us requiring us to reimburse Chunghwa Post Co., Ltd. in the amount of NT$768.0 million for land usage compensation due to the portion of land usage area in excess of our
ownership, along with interest calculated at 5% interest rate from June 30, 2005 to the payment date. However, we believe that both parties have the right to use co-managed land without consideration and thus Chunghwa Post Co., Ltd. does not
have the right to request land compensation payments. Furthermore, we also believe that the computation used to derive the land usage compensation amount is inaccurate because most of the compensation amount has expired as a result of the expiration
clause. On March 30, 2009, the Taiwan Taipei District Court rendered its judgment that we only need to pay approximately NT$17 million, along with interest calculated at 5% per annum from July 23, 2005, and 4% of Chunghwa Post Co.,
Ltd.s court fees as compensation. Chunghwa Post Co., Ltd. appealed to the Taiwan High Court on April 22, 2009. We also filed an appeal to the Taiwan High Court within the statutory period. On April 7, 2010, the Taiwan High Court
rendered its judgment, ruling that we need to pay approximately NT$23 million, in addition to the approximately NT$17 million from the Taiwan Taipei District Court judgment, along with interest calculated at 5% per annum from July 23,
2005, and 12.5% of Chunghwa Post Co., Ltd.s court fees from its original suit and subsequent appeal as compensation. We filed an appeal with the Supreme Court on April 22, 2010 and the Supreme Court reversed and remanded the judgment for
a new trial at Taiwan High Court in June 2011. On January 6, 2012, the Taiwan High Court ruled that we need to pay NT$4 million (US$0.1 million) to Chunghwa Post Co., Ltd., in addition to the amount as demanded by court in the Taipei District
Court judgment, along with interest calculated at 5% per annum from July 23, 2005. The decision of the court is final, and we made the payment in full accordingly by the end of 2012.

Enforceability of Judgments in Taiwan

We are a company limited by shares and incorporated under the Republic of China Company Act and the Statute of Chunghwa
Telecom Co., Ltd. All of our directors and executive officers, our supervisors and some of the experts named in this annual report are residents of Taiwan and a substantial portion of our assets and the assets of those persons are located in Taiwan.
As a result, it may not be possible for investors to effect service of process upon us or those persons outside of Taiwan, or to enforce against them judgments obtained in courts outside of Taiwan. We have been advised by our Republic of China
counsel that in their opinion any final judgment obtained against us in any court other than the courts of the Republic of China in connection with any legal suit or proceeding arising out of or relating to the ADSs will be enforced by the courts of
the Republic of China without further review of the merits only if the court of the Republic of China in which enforcement is sought is satisfied that:



| |  |  | the court rendering the judgment has jurisdiction over the subject matter according to the laws of the Republic of China;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | the judgment and the court procedure resulting in the judgment are not contrary to the public order or good morals of the Republic of China;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if the judgment was rendered by default by the court rendering the judgment, we were served within a reasonable period of time in accordance with the
laws and regulations of the jurisdiction of the court or process was served on us with judicial assistance of the Republic of China; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | judgments at the courts of the Republic of China are recognized and enforceable in the court rendering the judgment on a reciprocal basis.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------

A party seeking to enforce a foreign judgment in the Republic of China would be required to obtain foreign
exchange approval from the Central Bank of the Republic of China (Taiwan) for the payment out of Taiwan of any amounts recovered in connection with the judgment denominated in a currency other than NT dollars if a conversion from NT dollars to a
foreign currency is involved.

Regulation

Overview

We were subject to the Statute of Chunghwa Telecom Co.,
Ltd. prior to our privatization. Although we have been privatized, the Legislative Yuan has not yet abolished the Statute of Chunghwa Telecom Co., Ltd., and at this time, the Statute of Chunghwa Telecom Co., Ltd. is still applicable to us.

Regulatory Authorities

Prior to March 1, 2006, we were under the supervision of the Ministry of Transportation and Communications and the Directorate General of Telecommunications. On March 1, 2006, the NCC was formed
in accordance with the Organization Law, which was intended to transfer regulatory authority over the Taiwan telecommunications industry from the Ministry of Transportation and Communications and the Directorate General of Telecommunications to the
NCC. The NCC was comprised of nine commissioners who were recommended by the government and opposition political parties in the Legislative Yuan, as well as recommended by the Executive Yuan and approved by the Legislative Yuan. However, the
Executive Yuan considered the composition of the NCC unconstitutional and petitioned the Grand Justices of the Republic of China, or the Grand Justices, to interpret the constitutionality of the formation of the NCC and the procedure for nominating
commissioners to serve on the NCC. On July 21, 2006, the Grand Justices rendered an interpretation and held that the relevant provisions under the Organization Law as to the nomination procedures for the commissioners of the NCC were
unconstitutional. However, the Grand Justices granted a grace period allowing such provisions of the Organization Law to remain in effect until December 31, 2008.

On January 9, 2008, an announcement issued by the President amended the Organization Law, or New Amendment, amending the unconstitutional formation articles and reducing the total number of
commissioners to seven with a term of four years, but three of the commissioners appointed after the New Amendment serve a term of two years. The commissioners will be nominated by the premier of the Executive Yuan and approved and appointed by the
Legislative Yuan.

The new nomination method under the New Amendment became effective on February 1, 2008 when the
Legislative Yuan started its new term. The nine incumbent commissioners continued to serve until July 31, 2008, when their terms ended. The premier of the Executive Yuan nominated seven commissioners on July 1, 2008, and they were approved
and appointed by the Legislative Yuan on July 18, 2008. The new commissioners took office on August 1, 2008. Thereafter, upon the resignation of one commissioner and the expiry of the term for the three commissioners, four new
commissioners were nominated by the premier of the Executive Yuan, approved and appointed by the Legislative Yuan and began serving as commissioners on August 1, 2010. The Organization Law was further amended on December 28, 2011. The
amendment stipulates that the premier of the Executive Yuan shall appoint one Commissioner to serve as Chairperson, and one as Vice Chairperson upon nomination of the commissioners. Accordingly, the Chairperson, the Vice Chairperson and two new
Commissioners were nominated by the premier on April 30, 2012, approved and appointed by the Legislative Yuan and began tenure as commissioners on August 1, 2012.

In accordance with the Organization Law, the NCC is responsible for:



| |  |  | formulating, implementing and interpreting telecommunications laws and regulations;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | issuing telecommunications licenses and regulating the operation of telecommunications industry participants;

Each of these aspects is described below. The Telecommunications Act also establishes a
non-auction pricing system for assignment of radio frequencies.

Licensing of Telecommunications Services

Type I and Type II Service Providers

Under the Telecommunications Act, telecommunications service providers are classified into two categories:

Type I. Type I service providers are providers that install network infrastructure, such as network transmission,
switching and auxiliary equipment for the provision of telecommunications services. Type I services include fixed-line services such as local, domestic long distance and international long distance services, as well as interconnection, leased line,
ADSL and satellite services and wireless services such as mobile, including 3G mobile, paging, mobile data and trunked radio services.

Type II. Type II service providers are defined as all telecommunications service providers other than Type I service providers. Type II services are divided into special services and general
services. Special services include simple resale, VoIP international leased circuit and other services specified by the Ministry of Transportation and Communications before March 1, 2006 or by the NCC from March 1, 2006. General services
include any Type II service other than special services.

Until 1996, we were the sole provider of Type I
services in Taiwan. In 1996, the government opened the market for mobile, paging and trunked radio, mobile data and digital low power cordless telephone services. In 1998, the government opened the market for fixed-line and mobile satellite
services. In June 2001, the government granted licenses to three operators for establishing fixed-line services, thereby opening the market for fixed-line services. Since August 2000, the government has permitted four undersea cable operators to
engage in the undersea cable leased-circuit business.

Commencing in 2007, the NCC began accepting applications
for licenses to provide fixed-line services in March, June, September and December of each year. The NCC started to accept applications for fixed-line services on a daily basis beginning in 2008. There is no limit on the number of fixed-line
licenses that they may decide to issue.

Granting of Licenses

Type I

Type I service providers are more closely regulated than Type II service providers. The government has broad powers to limit the number of providers and their business scope and to ensure that they meet
their facilities roll-out obligations. Under the Telecommunications Act, Type I service providers are subject to pre-licensing merit review of their business plans and tariff rates.

Before March 1, 2006, licenses for Type I services were granted by the Ministry of Transportation and Communications
through a three-step procedure. Applicants obtained a concession from the Ministry of Transportation and Communications. After obtaining a concession, the applicant obtained a network construction permit and an assignment of spectrum, in the case of
mobile telephone services and satellite services, from the Directorate General of Telecommunications or the Ministry of Transportation and Communications prior to applying for a license. Upon completion of construction of its network and review by
the Directorate General of Telecommunications, the applicant was granted a Type I license. The Ministry of Transportation and Communications had the authority to grant Type I licenses for each of fixed-line services, wireless services and satellite
services. Type I licenses have different minimum paid-in capital requirements for applicants and varying durations depending on the particular type of service.

##### Table of Contents

Since March 1, 2006, the same procedure applies except that the
licenses are granted by the NCC.

The Telecommunications Act further authorizes the competent authority, now
the NCC, to promulgate separate regulations governing each Type I service, including the business scope of the Type I service provider, as well as the procedures and conditions for granting special permits and the length of the period of the special
permits of each Type I service. Each holder of a Type I license will pay a fee ranging from 0.5% to 2% of or their bid price ratio (Article 2 of the Type I Service Provider Special Tariff Standards) multiplied by their annual revenues generated from
the particular Type I service for which a license has been granted.

Fixed-line Services. Under the
Telecommunications Act, the Fixed Network Regulations govern the issuance of fixed-line service licenses and the business scope of fixed-line providers. Fixed-line service licenses are subdivided into the following categories:



| |  |  | integrated services, including local, domestic long distance, international long distance telephone services;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | local telephone services;
| | - |  | -------------------------



| |  |  | domestic long distance telephone services;
| | - |  | ------------------------------------------



| |  |  | international long distance telephone services; and
| | - |  | ---------------------------------------------------



| |  |  | local, domestic long distance and international long distance leased line services. We conduct our fixed-line services through a license for integrated
services.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------

Licenses for local telephone and integrated services are valid for 25 years.
Licenses for domestic long distance and international long distance telephone services are valid for 20 years. Licenses for leased line services are valid for 15 years. If the service provider wishes to continue operating, the service provider needs
to apply for a license renewal to the NCC between nine months and six months before the expiration of their license. The minimum paid-in capital requirements for integrated services providers that applied for a license before June 30, 2004,
between July 1, 2004 and January 31, 2008 and on or after February 1, 2008 are NT$21 billion, NT$8.4 billion and NT$6.4 billion, respectively. The minimum paid-in capital requirements for both domestic and international long distance
telephone service providers that applied for a license between July 1, 2004 and January 31, 2008 and on or after February 1, 2008 are NT$1.05 billion and NT$800 million, respectively. The minimum paid-in capital requirements for
international undersea leased cable service providers that applied for a license before June 30, 2004, between July 1, 2004 and January 31, 2008 and on or after February 1, 2008 are NT$420 million, NT$420 million and NT$320
million, respectively. The minimum paid-in capital requirement for local telephone service providers that applied for a license between July 1, 2004 and January 31, 2008 and on or after February 1, 2008 are NT$6.3 billion and NT$4.8
billion, respectively, multiplied by the Local Network Operation Weights for the regions in which local network managerial rights have been granted to the service provider. The Local Network Operation Weights are calculated as the population of the
region as a proportion of the entire population of Taiwan and are announced by the competent authority every three years. If an applicant for a license is also a Type I service provider, it will need to combine the minimum paid-in-capital
requirements for all relevant services.

In March 2000, the government granted three new concessions to
fixed-line services providers for integrated services. Recipients of these concessions are required to apply for a network construction permit to deploy broadband local access networks. Each recipient of these concessions is required to have
capacity for 150,000 customers before it is able to apply for a fixed-line license to launch its proposed services. The three fixed-line service providers have since obtained fixed-line licenses and are required to achieve capacity for one million
customers by the sixth year following the date of the grant of the network construction permit awarded. Operators that applied for integrated service provider licenses before June 30, 2004, between July 1, 2004 and January 31, 2008
and on or after February 1, 2008 must achieve a capacity for 1.0 million, 0.4 million and 0.3 million customers, ports or a combination of both, respectively, by the fourth year following the date of the grant of the network
construction permit.

Wireless Services. Under the Telecommunications Act, the Wireless
Regulations promulgated by the Ministry of Transportation and Communications before March 1, 2006 or by the NCC from March 1, 2006 continue to govern the issuance of wireless services licenses and the business scope of wireless service
providers. Wireless service licenses are subdivided into the following categories:



| |  |  | mobile services;
| | - |  | ----------------



| |  |  | paging services;
| | - |  | ----------------



| |  |  | mobile data services;
| | - |  | ---------------------



| |  |  | digital low-power cordless telephone services; and
| | - |  | --------------------------------------------------



| |  |  | trunked radio services.
| | - |  | -----------------------

Wireless service licenses are granted to both regional and national service providers through review and bidding procedures.

The wireless service license for mobile or paging service, once granted, should be valid for a term of 15 years starting
from the date when such license is granted, and licenses for mobile data, digital low-power cordless telephone and trunked radio are valid for 10 years starting from the date when such license is granted. According to the Regulations for
Administration of Mobile Communications Businesses amended by the NCC on September 19, 2011, the wireless service provider may file an application with the NCC for extension of the valid term of its license for providing mobile or paging
service one year prior to the expiry of the 15-year valid term. Once the NCC approves the application, the valid term of the wireless service license for mobile or paging service will be extended to June 30, 2017. The valid terms of our
licenses granted by the ROC government authorities for providing 2G mobile services on the 900MHz and 1800MHz spectrum will expire in 2012 and 2013 respectively. We filed the application with the NCC for extending the valid terms of our 2G licenses
on November 29, 2011. Our application was approved by the NCC in November 2012 and the terms of our licenses for providing 2G mobile services on the 900MHz and 1800MHz spectrum should be valid until June 2017.

The minimum paid-in capital requirements for different mobile communication businesses are as follows: Digital Low-Power
Wireless Telephone Business, NT$200 million; Trunking Wireless Telephone Business, NT$20 million for regional operation and NT$60 million for island-wide operation; Mobile Data Communication Business, NT$50 million for regional operation and NT$150
million for island-wide operation; Radio Paging Business, NT$200 million for regional operation and NT$400 million for island-wide operation; Mobile Telephone Business, NT$2 billion for regional operation and NT$6 billion for island-wide operation.
If one single applicant acquires operational licenses of two or more businesses with minimum paid-in capital requirements, the paid-in capital for the businesses should be calculated and collected by the applicant separately.

For an operator who obtains the permission of operation over two businesses through the legal procedure, its minimum
paid-in capital shall be separately calculated upon approval for establishment, if such other businesses are subject to the minimum paid-in capital restriction.

Third Generation Mobile Services. The Ministry of Transportation and Communications promulgated the Third Generation Mobile Telecommunications Services Regulations on October 15, 2001. The NCC
amended the above regulations on July 5, 2007, designating itself as the authority in charge of the third generation, or 3G, mobile services regulations and further amended such regulations on December 30, 2008 for the establishment of
base stations. The regulations govern voice and non-voice telecommunications services provided using the spectrum assigned by the Ministry of Transportation and Communications, and now governed by the NCC, that utilizes the IMT-2000 technical
standards as announced by the International Telecommunications Union. Licenses for 3G mobile services were granted by the Ministry of Transportation and Communications and are now granted by the NCC. We have received our 3G mobile services license,
which is valid from May 26, 2005 to December 31, 2018.



53



---

##### Table of Contents

Under the Third Generation Mobile Telecommunications Services
Regulations, the operation area of this business is the whole nation; the minimal paid-in capital for operating this business shall be NT$6 billion. If the applicant operates another business of a Type I telecommunications enterprise at the same
time and there is a restriction on the paid-in capital to the other business, after acquiring the establishment approval, the required minimal paid-in capital shall be calculated by aggregating the minimal requirement of each service. A company
holding a 3G mobile license and having 200 or more shareholders is required to become a public company, which is subject to the stringent disclosure requirements under the securities regulations of the ROC A company holding a 3G mobile license is
also required to submit a report to the NCC within 20 days after its shareholders approve the capital reduction of such company, the entering into, modification or termination of any contracts regarding leasing of all business, outsourcing of
operations or joint operations, the transfer of the whole or substantial part of the business or assets of such company, and taking over of the whole of the business or assets of any other company which would have a significant impact on such
companys operations.

Satellite Services. Under the Telecommunications Act, the Satellite
Regulations promulgated by the Ministry of Transportation and Communications govern the issuance of satellite services licenses and the business scope of satellite service providers. The NCC amended the above regulations on July 20, 2007,
designating itself as the authority in charge of the Satellite Regulations. Satellite services licenses are subdivided into fixed satellite services licenses and mobile satellite services licenses.

The satellite services license should be valid for a term of 10 years starting from the date when such license is granted.
If the service provider wants to re-new its satellite services license before the expiry of the 10-year term, such service provider needs to file a renew application with the NCC within the period from 9 months to 6 months before the expiry date of
the original satellite license. The valid term of the renewed satellite license will be 10 years. Minimum paid-in capital requirements for fixed satellite services providers and mobile satellite services providers are NT$100 million and NT$500
million, respectively.

We currently hold a fixed satellite services license, valid from December 10, 2008
to December 9, 2018.

Type II

The Telecommunications Act was amended in 1996 to open the market for all Type II services. Under the Type II Services
Regulations, Type II services are divided into special services and general services. Special services include simple resale, VoIP, network telephone service of E.164 and non-E.164 user numbers (IP Phone Numbers), international leased circuit and
other services specified by governing authority. General services include any Type II service other than special services. The policy for granting a Type II service license is as follows:



| |  |  | there is no limit on the number of licenses to be issued;
| | - |  | ---------------------------------------------------------



| |  |  | licenses were granted by the Directorate General of Telecommunications before March 1, 2006 and are now granted by the NCC; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | no bidding procedure is required.
| | - |  | ---------------------------------

We hold a license to operate all Type II services. Type II service licenses issued before November 15, 2005 are valid for ten years and may be renewed by application made two months prior to the
expiration date. Type II service licenses issued or renewed on or after November 15, 2005 are valid for three years and may be renewed during the period commencing two months prior to the expiration date. There is no minimum paid-in capital
requirement for Type II service providers. Our license to operate Type II services is included in our license to operate integrated services, and is valid from July 29, 2000 to July 28, 2025.

##### Table of Contents

Under regulations governing the fees payable for Type II licenses, operators
of simple resale or network telephone services of E.164 or non-E.164 user numbers must pay an annual license fee equal to 1% of annual revenues generated from these services during the previous year. Type II service operators providing services
other than simple resale or network telephone services of E.164 or non-E.164 user numbers must pay license fees ranging from NT$6,000 to NT$150,000 depending on their respective paid-in capital. For operators who operate over two or more businesses,
their license fee shall be separately calculated but jointly collected. The regulations do not apply to integrated services providers who are permitted to provide Type II services without additional Type II Licenses.

The Directorate General of Telecommunications started to process the applications for allocating E.164 and non-E.164 user
numbers (IP phone numbers) on November 15, 2005. A few operators, including our company, have applied for IP phone numbers. We applied to the NCC for E.164 user numbers and as of January 30, 2008, we have received approval to build a
network with a capacity of 30,000 numbers. As we are governed by fixed-line regulations, we need to receive approval from the NCC for our operation rules, tariff and service agreement for IP phone numbers before we can commence E.164 service. We
filed with NCC to return 30,000 E.164 numbers, and the application was approved by the NCC on July 1, 2011. Please refer to B. Business Overview for further discussion.

Telecommunications Numbers

According to the Telecommunications Act, numbering codes, subscriber numbers, identification numbers and other telecommunication numbers will be distributed and managed by the NCC. These telecommunication
numbers may not be used or changed without approval by the NCC. In order to maintain effective use of available telecommunication numbers, the Telecommunications Act empowers the NCC to reallocate and retrieve and to collect a usage fee for
distributed telecommunication numbers. The NCC promulgated the Fee Standards for Special Telecommunication Numbers on March 18, 2010, effective immediately, requiring telecommunications service providers to pay 70% of revenues collected from
the auctioning off and selection of golden numbers and the standard usage rates for special identification numbers in use.

Restrictions on Dominant Telecommunications Services Providers

Under the Telecommunications Act, the regulations governing dominant telecommunications services providers apply only to Type I service providers. A Type I service provider is deemed to be dominant if it
meets any of the following criteria and was declared by the Ministry of Transportation and Communications or now the NCC as dominant:

In addition, a dominant Type I service provider is subject to special regulations limiting
its tariff changes.

Tariff Control and Price Cap Regulation

In order to promote competition in the telecommunications market, and as part of the governments overall policy
toward deregulation, the Telecommunications Act was amended in 1999 to abolish the former rate of return system on tariff setting in favor of price cap regulation of Type I services.

Under the Administrative Regulations Governing Tariffs of Type I Telecommunications Enterprises, a dominant Type I service
provider must submit its proposed adjustment in primary tariffs and promotional packages to the NCC for approval at least 14 days prior to the date of the proposed tariff changes and announce such change on media, website and business locations on
the day after the NCC grants the approval. The tariff change will come into effect seven days after the announcement.

Primary tariffs include:



| |  |  | for fixed-line local telephone services: monthly fees, usage fees, monthly rental fees of leased lines and pay telephone usage fees;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | for fixed-line domestic long distance telephone services: usage fees and monthly rental fees of leased lines;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | for fixed-line international long distance telephone services: usage fees and leased line monthly rental fees;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | for wireless services, including 3G mobile services: monthly rental fees and usage fees;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | for internet services provided by dominant Type I service providers: connection and usage fees; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | other fees or tariffs announced by the Directorate General of Telecommunications before March 1, 2006 or by the NCC from March 1, 2006.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------

In addition, a dominant Type I service provider is required to set wholesale prices for the
provision of its telecommunication services to other telecommunication enterprises. These telecommunication services and their suitable targets, all of which are subject to annual reviews by the NCC, include:



| |  |  | interface circuits (local and long distance) between internet access service providers and customers for Type I and Type II service providers
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



56

##### Table of Contents

| |  |  | interface circuits (local and long distance) between internet access service providers for Type I and Type II service providers that are internet
access service providers
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | interconnection circuits between Type I service providers and between Type I and Type II service providers of international simple resale, or ISR, and
E.164 VoIP services
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | DSL-family (xDSL) circuits for fixed-line service providers and internet service providers
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | other local and long distance data circuits for Type I and Type II service providers
| | - |  | ------------------------------------------------------------------------------------



| |  |  | broadband internet interconnection for Type I and Type II service providers that are internet access service providers.
| | - |  | -----------------------------------------------------------------------------------------------------------------------

The initial wholesale prices set by a dominant Type I service provider may be the retail price less fees and expenses
which need not be incurred, but shall not be higher than its promotional pricing. Changes in the wholesale price charged by a dominant Type I service provider may not be greater than (i) the retail price less fees and expenses which need not to
be incurred but not greater than the promotional pricing; or (ii) the annual growth rate of the consumer price index in Taiwan minus the constant set by the NCC, whichever is the lower. The Administrative Regulations Governing Tariffs of Type I
Telecommunications Enterprises further prohibits a dominant Type I service provider from practicing unfair competition against other telecommunication enterprises.

In comparison, all non-dominant Type I service providers are required to notify the NCC and the public of their proposed
tariff adjustments seven days prior to the date of the proposed tariff change with respect to all tariffs. In addition, changes in tariffs charged by Type I service providers (notwithstanding the type of their respective services) may not, in any
event, be greater than the annual growth rate of the consumer price index in Taiwan adjusted by an adjustment coefficient, which will be periodically determined and announced by the NCC. For example, if:



| |  |  | the annual growth rate of the consumer price index in Taiwan minus the adjustment coefficient is positive, the increased percentage of tariffs must not
exceed such positive figure;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the annual growth rate of the consumer price index in Taiwan minus the adjustment coefficient is negative, the decreased percentage of tariffs must be
at least the absolute value of such negative figure, and the tariffs used in the given year must not be higher than the decreased tariff; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the annual growth rate of the consumer price index in Taiwan minus the adjustment coefficient equals to zero, no increase in tariffs is allowed to be
made by any Type I service providers.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

On January 29, 2010, the NCC announced that
effective April 1, 2010 to March 31, 2013:



| |  |  | the adjustment coefficient to be applied to the tariff adjustment for the fixed-line integrated services is 4.816% and covers the following:
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | dominant providers of fixed-line services

##### Table of Contents

Type II service providers are free to establish their own tariff schemes,
but are required to notify the NCC and the public upon adoption and upon any subsequent adjustments. The NCC approved our tariff adjustment plan on March 24, 2010.

The NCC announced an amendment of Administrative Regulation Governing Tariffs of Type I Telecommunications Enterprises,
other applicable regulations and the adjustment coefficient on February 7, 2013. The material amendments are set forth below:



| |  |  | Only the dominate service provider will be subject to the restrictions on adjustment of the tariffs charged;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | The adjustment of retail tariff charged for communications of long distance networks, international networks, and mobile (except for mobile prepaid
calling card) will no longer be subject to NCCs prior review and approval;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The coefficient applied to calculate the amount of xDSL monthly rents for local and long distance network circuits and other five wholesale services
provided by the dominant providers will be adjusted to 5.1749%, which means the amount of rents will decrease for the fourth straight year; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The amount of other primary tariffs charged by dominate service providers shall not be raised until March 31, 2017.
| | - |  | -------------------------------------------------------------------------------------------------------------------

Accounting Separation System

The Telecommunications Act requires that a Type I service provider, including one who concurrently offers Type II services, separately calculate the profits and losses for its different businesses, or
operating items, and prohibits any cross-subsidization among businesses, or operating items, that will impede fair competition.

Interconnection Arrangements

The Telecommunications Act requires all Type I service providers to allow other Type I service providers access to their networks. It further requires Type I service providers, within three months upon
request by the other Type I service provider, to reach an agreement on the relevant terms for the interconnection. Prices charged for interconnection must be based on cost. If the parties fail to reach an agreement within three months, the NCC may,
either at the request of the parties or on its own accord, arbitrate and determine the interconnection terms for the parties. The Telecommunications Act authorizes the Directorate General of Telecommunications or, from March 1, 2006, the NCC to
issue rules and regulations pertaining to interconnection.

The Administrative Rules for Network
Interconnection establishes the basis for determining the interconnection charge of a dominant Type I service provider, which shall be reviewed every four years. The interconnection charge of a dominant Type I service provider shall be reviewed by
the NCC in advance, and the NCC has the right to modify the rate.

A dominant Type I service provider shall unbundle its network elements. The
unbundled network elements shall contain the following:



| |  |  | local loops;
| | - |  | ------------



| |  |  | local switch transmission equipment;
| | - |  | ------------------------------------



| |  |  | local trunks;

Unless otherwise provided by the laws, interconnection charge of the providers for mobile communications businesses and the 3G mobile communications business should be calculated based on the decrees
issued by NCC. The foregoing shall apply, mutatis mutandis, to the calculation and reviewing method of the interconnection charge of the dominant providers for fixed communication services.

Unbundled network components of the providers for mobile communications businesses and the 3G mobile communications
business include:



| |  |  | mobile telecommunications trunks;
| | - |  | ---------------------------------



| |  |  | mobile telecommunications base stations;
| | - |  | ----------------------------------------

| | - |  | ------------------------------------------------------------



| |  |  | other items recognized by the NCC.
| | - |  | ----------------------------------

The Administrative Rules for Network Interconnection Between Telecommunication Service Providers was further amended by the NCC on November 2011 specifying the charges for network interconnection among
Type I service providers as follow:



| |  |  | Before January 1, 2011, except for international communications, tariffs for communications between a mobile telecommunications network and a
fixed-line network were collected from the call-originating subscribers by the call-originating service provider pursuant to the tariff schedules set by the mobile communication service provider, and revenues or any uncollectible accounts from such
tariffs went to the mobile service provider. However, from January 1, 2011, although the tariffs shall still be paid by the call-originating subscribers, the tariff schedules are set by the call-originating network service provider, and
revenues or any uncollectible accounts from such tariff shall go to the call-originating service provider. During the transition period from January 1, 2011 to December 31, 2016, we, as a dominant Type I fixed-line service provider, shall
pay extra transition fee in addition to access charges to the mobile communications service providers.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Bottleneck Facilities

Under the Telecommunications Act, when a Type I service provider cannot construct bottleneck facilities within a
reasonable period of time or substitute those facilities with other available technologies, it may request for co-location on a fee basis from the owner of the facilities located at the bottleneck of the relevant telecommunications network. The
owner of the facilities so requested may not reject these requests without due cause. The NCC has the authority to prescribe facilities as bottleneck facilities, and has prescribed bridges, tunnels, lead-in tubes and telecommunications chambers
located within buildings and horizontal and vertical telecommunications cables and lines as bottleneck facilities in relation to fixed-line telecommunications networks. The NCC, in an announcement on December 21, 2006, has defined local loop
facilities as the bottleneck of the telecommunications network and amended the Administrative Rules for Network Interconnection Between Telecommunication Service Providers in April 2007, providing that we, as a Type I service provider,
can only charge other local telephone service providers at cost for local loop services. The rental tariff is derived from a cost basis and must be approved by the NCC each year.

Spectrum Allocation

The Ministry of Transportation and Communications is responsible for allocating all telecommunications related frequencies primarily according to the standards set by the International Telecommunications
Union. The NCC is responsible for the licensing of operators to use these frequencies. The 900 MHz and 1,800 MHz frequency bands have been allocated for 2G mobile services and the licenses will be expired in June 2017. A total of 40 MHz of FDD
spectrum around the 850 MHz frequency band and a total of 110 MHz of FDD spectrum and 20 MHz of TDD spectrum around the 2 GHz band have been allocated for 3G mobile services.

##### Table of Contents

The Executive Yuan announced in September 2012 to open up the 4G/mobile
broadband licenses, and the NCC will complete the auction process for the 135MHz paired FDD spectrum over 700 MHz, 900 MHz, and 1800MHz frequency bands by December 2013.

Provision of Universal Services

Under the
Telecommunications Act, a Type I service provider may be required by the NCC, previously the Ministry of Transportation and Communications, to provide universal telecommunications services in remote or unprofitable areas. These services include
voice communication services, such as public phones, and data communication services, such as internet provision for libraries and public primary and secondary schools. All Type I service providers and certain Type II service providers designated by
the NCC, previously the Ministry of Transportation and Communications, will be required to contribute a fixed portion of their annual revenues to a universal services fund. Such a fund will be used to compensate for any losses, bad debts and
management fees incurred by the relevant Type I service provider in providing the universal services. All providers of universal services cannot refuse any request for service, unless for legitimate reasons, and cannot charge more than the
predetermined tariffs.

Equal Access

As a result of the liberalization of Taiwans telecommunications industry, a Type I service provider, including a 3G
mobile services provider and a WiMax service operator, is required to provide its customers with equal access to the domestic and international long distance telephone services provided by other service providers. A Type I service provider may
provide equal access through pre-selection or call-by-call selection. Before July 1, 2005, all Type I service providers, including us, provide equal access only through call-by-call selection. When a customer makes a call using call-by-call
selection, such customer has the option to select a service provider by dialing the network identification prefix assigned to the service provider of his choice. This will result in the automatic selection of the preferred service provider for the
provision of relevant telecommunication services. Starting from July 1, 2005, all Type I service providers also provide equal access through pre-selection in Keelung City, Taipei City/ County, Taichung City/County and Kaohsiung City/County.
Equal access through pre-selection is available throughout Taiwan since January 1, 2006. The pre-selection function allows any customer to select in advance a long distance or international service provider of his or her choice. When such
customer makes a call using this function, the communications network will automatically interconnect to the long distance or international network previously selected by such customer.

Number Portability

According to the Telecommunications Act and the Administration Rules Governing Number Portability, Type I service providers shall provide number portability service which enables customers to retain their
existing local and toll free fixed-line telephone numbers or mobile phone numbers when they switch from the original Type I service provider to other Type I service provider. Meanwhile, Type I service providers shall mutually grant each other number
portability services on a reciprocal basis, and shall conform in accordance with the principle of impartiality and reasonableness, and shall not be discriminatory.

Under the regulation, we are required to provide number portability service for fixed-line customers in Taipei City, New
Taipei City, Keelung City, Taichung City, Kaohsiung City and other areas where there are two or above fixed-line service providers. We have also provided number portability service for mobile communication customers since October 15, 2005.
Pursuant to the regulation, we shall compile and submit related information of number portability for the previous six months to NCC by January 10 and July 10 of each year.

Local Loop Unbundling

In December 2006, the NCC defined the local loop as facilities at the bottleneck of telecommunications
networks in accordance with the Regulations Governing Fixed Network Telecommunications Businesses. The NCC requires us to unbundle the local loops and allow other telecommunications operators to use these connections. The local loop or last
mile connections are the physical wire connections between the telephone exchanges central office to the customers premises usually owned by the incumbent telephone company. The NCC further amended the Administrative Rules for
Network Interconnection between Telecommunication Service Providers in April 2007 which provides that we can only charge other local telephone service providers at cost for local loop services instead of on the basis of commercial
negotiations.

Co-location

We have been declared by the former competent authority NCC as a dominant Type I service provider for fixed-line and
mobile services. According to the Telecommunication Act, the Regulations Governing Fixed Network Telecommunications Businesses and the Administrative Rules for Network Interconnection between Telecommunication Service Providers, if any other service
provider requests for co-location, we must negotiate with them, unless otherwise provided by laws or regulations. As of the end of 2012, we are currently co-locating 27 POI sites and two cable stations with other Type I fixed-line service providers
and 10 POI sites with other Type I mobile service providers.

Ownership Limitations

The laws of the Republic of China limit foreign ownership of our common shares. Prior to March 1, 2006, the Ministry
of Transportation and Communications, as the competent authority under the Telecommunications Act, had the power to prescribe the limits on foreign ownership of our common shares. After the formation of the NCC on March 1, 2006, the NCC
replaced the Ministry of Transportation and Communications as the competent authority under the Telecommunications Act pursuant to the Organization Law. On July 18, 2006, the Ministry of Transportation and Communications and the NCC reached an
agreement where the Ministry of Transportation and Communications will have the authority to adjust foreign ownership limits only after negotiations with the NCC. On June 14, 2007, we applied to both the NCC and the Ministry of Transportation
and Communications, asking for an increase in direct and indirect foreign ownership cap of our common shares. After consultation with the NCC, the Ministry of Transportation and Communications raised our foreign ownership cap of direct and indirect
shareholdings from 49% to 55%. Our foreign ownership limitation of total direct shareholdings remained at 49%.

Under the current Telecommunications Act, the Chairman of a Type I service provider is required to be a citizen of the
Republic of China.

Fair Trade Act

The requirements and restrictions under the Telecommunication Act regarding price control, IP peering, equal access and accounting separation regulates certain competitive activities among
telecommunication industries and aims to reduce the occurrence of anti-competition activities.

By comparison to the
Telecommunications Act, the Fair Trade Act, or the FTA, plays a more comprehensive role in regulating all matters relating to competition between enterprises. The Fair Trade Act seeks to deter and prevent anti-competitive conduct by granting the
Fair Trade Commissions powers to investigate and to impose penalties.

The Fair Trade Act is administered and enforced
by the Fair Trade Commission, or the FTC, which has independent administration rights granted to it under the Fair Trade Act and is empowered to impose disciplinary actions for fair trade matters. The Fair Trade Commission may initiate an
investigation either on its own account in accordance with its discretion granted by the Fair Trade Act or upon receipt of a complaint.

Regulation on Telecommunication Enterprise with Monopoly Status

The term monopoly used in the FTA refers to the circumstance where an enterprise conducts its business
operation in a relevant market without facing any competition or where an enterprise is able to dominate the relevant market and block competition in the market. If there are two or more enterprises within the same market that do not engage in any
price competition with each other, the whole group of non-competing enterprises should be deemed as a single monopoly enterprise in the market.

According to the FTA, an enterprise or a group of enterprises will not be considered as monopolistic enterprise(s) if none of the following circumstances exists:



| |  |  | the market share of the enterprise in a relevant market reaches one-half of the market;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | the combined market share of two enterprises in a relevant market reaches two-thirds of the market; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | the combined market share of three enterprises in a relevant market reaches three-fourths of the market.
| | - |  | --------------------------------------------------------------------------------------------------------

If the market share of any respective enterprise does not reach one-tenth of the relevant market or if the amount of the
enterprises total sales in the preceding fiscal year is less than one billion NT dollars, such enterprise shall not be considered as a monopolistic enterprise in the relevant market. Notwithstanding the above, the FTC has the ultimate
discretion to consider an enterprise as a monopolistic enterprise upon any other events evidencing such enterprises capability to affect the supply and demand in relevant market or eliminate competition.

Under the FTA, any enterprise with monopoly status is prohibited from engaging in any of the following activities:



| |  |  | directly or indirectly, by using any unfair method to prevent any other enterprises from competing;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | improperly set, maintain or change the price for goods or the remuneration for services;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | forcing the enterprises trading counterpart to give preferential treatment without justification; or
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | abusing its market power.
| | - |  | -------------------------

According to the FTCs Explanation on Regulations Governing Telecommunication Industry, a telecommunication enterprise with monopoly status is likely to be involved with the following activities
regulated by the FTA: conducting predatory pricing, price squeezing, cross-subsidies, price discrimination, blocking access to essential facilities, entering into long-term agreements to restrict the ability to change counterparties.

Regulations on Combination Between Telecommunication Enterprises

The term merger used in the FTA refers to any of the following circumstances:



| |  |  | where an enterprise and another enterprise are merged into one;
| | - |  | ---------------------------------------------------------------



| |  |  | where any enterprise holds or acquires more than one-thirds of total voting shares or capital of another enterprise;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | where any enterprise is assigned by or leases from another enterprise the whole or the major part of the business or properties of such other
enterprise;

| |  |  | where any enterprise directly or indirectly controls the business operation or the appointment or discharge of personnel of another enterprise.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------

If any merger between or among multiple enterprises falls within any of the following
circumstances, a prior approval granted by the FTC shall be required:



| |  |  | as a result of the merger, the enterprise will own at least one-third of the total market share;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | there is any enterprise involved with the merger has one fourth of the market share; or
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | the sales amount for the preceding fiscal year of one of the enterprises involved with the merger exceeds the threshold amount publicly announced by
the FTC from time to time.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Once the telecommunication enterprise files the merger
application with the FTC, the FTC will evaluate the pros and cons of the merger by weighing the potential economic efficiency against the disadvantage of reduced competition. If the FTC finds the potential economic efficiency generated from the
merger should be able to offset the disadvantage of reduced competition caused, the FTC will grant the approval for the merger.

Regulations on Concerted Action (Cartel) in Telecommunication Industry

The term concerted action (cartel) as used in the FTA means the conduct of any enterprise, by means of
contract, agreement or any other form of mutual understanding, with any other competing enterprise, to jointly determine the price of goods or services, or to limit the terms of quantity, technology, products, facilities, trading counterparts, or

Changes in our revenue composition and sources of revenue growth

Our domestic fixed communications business revenues are derived primarily from the provision of local, domestic long distance, broadband
access, leased line service, MOD, domestic data services and domestic other services including information and communication technologies, cloud services, corporate solution services, billing handling services and the leasing of real estate
properties. In addition, we also derive fixed-line revenues from providing interconnection services to other carriers. Our revenues from mobile communications business are principally derived from the provision of mobile services, sales of mobile
handsets and data cards and mobile other services. Our revenues from internet business are generated principally from HiNet internet service, internet VAS, data communication services, internet data center, and internet other services including
information and communication technologies and cloud services. Our revenues from international fixed communications business derived primarily from international long distance, international leased line, international data services, satellite
services, and international other services. Our other revenues are principally derived from non-telecom services.

The table
below sets forth the revenues from our principal lines of business as a percentage of total revenues for the periods indicated.

Our domestic fixed communications business has been an important source of revenue over the last three
years. We derive domestic fixed communications from the provision of ADSL and FTTx access services that provides customers with data access lines. The percentage of total revenues derived from domestic fixed communication increased in 2011 was
mainly due to the change in policy for collecting the tariffs for fixed-to-mobile calls from mobile service providers to fixed communications service providers since January 1, 2011, which gave our fixed communications business the right to set
and collect the tariffs for fixed-line-to-mobile phone calls. The percentage of total revenues derived from domestic fixed communication decreased in 2012 was mainly due to tariff reductions for ADSL and domestic long distance call services and the
decline of local call service revenue because of mobile and VoIP substitution. We believe that domestic fixed communications business will continue to generate a significant portion of our revenues.

Revenues from our mobile communications business made a major contribution to our revenues over the last three years. While the change in
policy for collecting the tariffs for fixed-to-mobile calls has caused a decline in our mobile communications business revenues, we have experienced a significant increase in revenues generated by our mobile value-added services due to increased
smart phone and mobile internet use by our subscribers. As a result, we believe that our mobile communications business will continue to generate a significant portion of our revenues.

Our internet business was another important source of revenues over the last three years. We derived internet business revenues from the
provision of HiNet Internet service and Internet value-added services. The percentage of revenues from internet services within total revenues decreased in 2012 compared to 2011, mainly due to the tariff reduction in internet services along with the
ADSL tariff reduction.

##### Table of Contents

Our international fixed communications business was also an important source of our revenues
over the last three years. We derived our international fixed communications revenues mainly from international long distance telephone services, international leased line services and international data services. The revenues from our international
fixed communications business as a percentage of our total revenues remained flat from 2011 to 2012, while international long distance telephone services revenue continued to decline due to VoIP substitution.

Our other revenues decreased from 2011 to 2012 primarily due to lower property sales by our subsidiary, Light Era Development Co., Ltd.,
in 2012 compared to 2011.

Tariff adjustments

We adjust our tariffs and offer promotional packages from time to time primarily in response to market conditions. We also from time to time are required to adjust our pricing in line with domestic
regulations.

The NCC passed a resolution on December 21, 2006 adopting a price reduction plan requiring the continuous
reduction in telecommunication tariffs over three years. Minimum reductions of 4.88% for fixed-line to mobile call tariffs, 4.88% for the tariffs of our highest monthly rate plan, 4.88% for mobile prepaid calling card tariffs and 5.35% for ADSL
tariffs must be made each year. The price reduction plan also required us to stop collecting a NT$5.0 monthly maintenance fee from our fixed-line customers who have paid at least 20 years worth of tariffs and customers who chose self-maintenance
starting January 1, 2008 and a NT$70.0 fixed-line basic charge from our ADSL customers who only use data services. On January 29, 2010, the NCC announced a new tariff reduction plan starting on April 1, 2010 to March 31, 2013.
The percentage of decrease set by NCC was DCPI- 4.816% for IP Peering fees, domestic leased-line fees, ADSL access fees and long distance tariffs, and DCPI-
5.00% for fees for mobile calls to local fixed-lines and other networks and domestic mobile SMS, where DCPI is the year-over-year change of the consumer price index of previous year released by the
Directorate-General of Budget, Accounting and Statistics of the Executive Yuan. The DCPI for 2010 that was used for the tariff reduction starting from April 1, 2011 was 0.96%; the DCPI for 2011 that was used for the tariff reduction starting from April 1, 2012 was 1.42%; and the DCPI for 2012 that was used for the tariff reduction
starting from April 1, 2013 was 1.93%. On February 7, 2013, the NCC announced a new plan for tariff reductions in wholesale tariffs for IP peering and domestic leased line services, and in monthly fees for fixed-line broadband services
(excluding fiber-to-the-home, or FTTH, and fiber-to-the-building, or FTTB) over a period of four years starting on April 1, 2013, which are subject to a reduction by DCPI -5.1749%. While mobile
tariffs will not be regulated in this round, according to the revised Administrative Rules for Network Interconnection, the mobile interconnection fees should be reduced from the current NT$2.15 per minute to NT$1.15 per minute, over the period of
four years starting from January 5, 2013. In addition, each operator was required by the NCC to submit a mobile voice service tariff reduction plan along with the interconnection rate reduction, and the new mobile voice service tariffs became
effective on April 1, 2013.

On January 1, 2011, we implemented the NCCs change in policy for collecting the
tariffs of fixed-line-to-mobile calls from mobile service providers to fixed communications service providers. As a result, our fixed communications business now has the right to set and collect the tariffs for fixed-line-to-mobile phone calls.

On June 22, 2011, we implemented a discounted tariff along with broadband speed upgrade for our broadband service, under
which we provided a 30% or more discount to subscribers of 20 Mbps, 50 Mbps or 100 Mbps broadband access services. We further reduced our ADSL tariffs by approximately 20% starting from 2012 in order to attract more broadband customers. In April
2013, we implemented another discounted tariff for our ADSL and fiber broadband service.

In addition, in 2011, there were
complaints from the general public regarding our mobile data network congestion. To address the situation, we adopted measures such as offering a 20% discount of the mobile data monthly fees from August 2011 to the end of 2012 for customers whose
monthly data usage volume was less than one gigabyte.

As requested by the Legislative Yuan and NCC, we implemented a
discounted tariff for telecommunication services from Kinmen, Matsu and Penghu Islands to Taiwan in April 1, 2011. We further applied one single tariff to all the telecommunication services for the entire country since January 2012.

##### Table of Contents

We expect to continue to adjust tariffs and offer a variety of promotional packages from
time to time in response to increasing competition and in order to take advantage of our pricing power from economies of scale. We may also be required to adjust our pricing due to changes in domestic regulations.

Capital expenditures as a result of technological improvements and changes in our business

In recent years, we have focused on modernizing and upgrading our mobile services network and on developing our FTTx network, which
enables transmission of digital information at a high bandwidth over fiber loops. In particular, we have enhanced our telecommunications services through:



| |  |  | the introduction of a IP-based exchange system in our long distance telephone network;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | the implementation of a network modernization program, including a gradual transfer from our public switched telephone network to a system based on
internet protocol, to remain at the forefront of new technologies;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the development and deployment of Green IDC for meeting the new demands of cloud computing services;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | the deployment of a high-capacity long-haul reconfigurable optical add drop multiplexing system and a nationwide internet protocol backbone network
with thousands of Gbps switching routers for internet and managed IP services; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the expansion and upgrade of our mobile services network as well as WiFi/Femtocell to improve indoor and outdoor 3G mobile network coverage and
transmission speed for mobile internet.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result, we made aggregate capital expenditures of NT$140.4
billion over the period from January 1, 2008 to December 31, 2012.

Our long-term goal is to optimize our capital
expenditures by focusing on investing in innovative products and services with attractive return profiles. We evaluate our investment opportunities by benchmarking them against internal return requirements. We are upgrading our public switched
telephone network to a next-generation network, which will have more capacity, greater upgrade flexibility, and increased operational efficiencies. We have also devoted resources toward the effective upgrade of our 3G mobile network to 3.5G and
HSPA+/Dual cell HSPA+ and the continuing build-out of our FTTx infrastructure. In addition, we are planning to deploy green internet Data Centers and service delivery network for the innovative services, such as cloud computing, fixed mobile
convergence services and four-screen digital convergence services.

Provisions for pension payments to our employees

Personnel expenses constitute a significant portion of our operating costs and expenses. In 2010, 2011 and 2012, personnel expenses
represented 30.4%, 27.6% and 25.9% of our total operating costs and expenses, respectively, and pension costs represented 2.0%, 1.8% and 1.8% of our total operating costs and expenses, respectively. The table below sets forth information regarding
our personnel expenses and as a percentage of our total operating costs and expenses for the periods indicated.

At the time of our privatization, we settled all of our then existing defined benefit
pension obligations in full. After completing our privatization on August 12, 2005, all of our continuing employees were deemed to have commenced employment as of August 12, 2005 for seniority purposes under our pension plans in effect after
privatization. Under applicable Republic of China regulations, upon our privatization, the Ministry of Transportation and Communications assumed the obligation to make annuity payments to all of our employees that retired before our privatization.

Taxation

The income tax rate for profit-seeking enterprises is 17% in the Republic of China. We benefit from tax incentives, including tax credits of up to 15% of some of our research and development expenses in
accordance with the Statute for Innovating Industries. We also qualify for tax benefits at a rate of 5% to 15% of our investment amount for qualified equipment and technology under the Statute for Upgrading Industries. However, due to the expiration
of the Statute for Upgrading Industries at the end of 2009, we will no longer receive tax credits for new investments in automation, employee training expenditures incurred, and equipment and technology purchased after January 2010. As a result,
though our effective tax rate was 15.8%, 15.2% and 16.1% in 2010, 2011 and 2012, respectively, our effective tax rate may rise in the future because of fewer tax incentives.

In 1997, the Income Tax Law of the Republic of China was amended to integrate corporate income tax and stockholder dividend tax to eliminate the double taxation effect for resident stockholders of Taiwan
companies. Under the amendment, all retained earnings generated from January 1, 1998 and not distributed to stockholders as dividends in the following year are assessed with a 10% retained earnings tax. See Item 10. Additional
InformationE. TaxationRepublic of China TaxationDividends. This has not had an impact on our financial results of operations because of our high dividend payout policy.

Critical Accounting Policies

Summarized below are our accounting policies that we believe are both important to the portrayal of our financial results and involve the need for management to make estimates about the effect of matters
that are uncertain in nature. Actual results may differ from these estimates, judgments and assumptions. Certain accounting policies are particularly critical because of their significance to our reported financial results and the possibility that
future events may differ significantly from the conditions and assumptions underlying the estimates used and judgments made by our management in preparing our financial statements. The following discussion should be read in conjunction with the
consolidated financial statements and related notes, which are included in this annual report.

Revenue Recognition

We recognize revenues when we have persuasive evidence of an arrangement, the goods have been delivered or the services have been rendered
to the customer, the sales price is fixed or determinable and collectability is reasonably assured. We measure revenues at the fair value of the consideration received or receivable and represents amounts agreed between us and the customers for
goods sold in the normal course of business, net of sales discounts and volume rebates. The costs of providing services are recognized as incurred.

Usage revenues from fixed-line services (including local, domestic long distance and international long distance), cellular services, internet and data services and interconnection and call transfer fees
from other telecommunications companies and carriers are billed in arrears and are recognized based upon seconds or minutes of traffic processed when the services are provided in accordance with contract terms.

We recognize other revenues as follows: (i) one-time subscriber connection fees (on
fixed-line services) are deferred and recognized over the average expected customer service periods, (ii) monthly fees (on fixed-line services, mobile and internet and data services) are accrued every month, and (iii) prepaid services
(fixed-line, mobile and internet and data services) are recognized as income based upon actual usage by customers or when the right to use those services expires. Where we enter into transactions which involve both the provision of air time bundled
with products such as 3G data card and handset, total consideration received from handsets in these arrangements is allocated and measured using units of accounting within the arrangement based on relative fair values limited to the amount that is
not contingent upon the delivery of other items or services. Relative fair values are based on the selling prices of 3G data cards and handsets sold on a standalone basis and the monthly fees on the subscription contracts.

Where we sell products to third-party cellular phone stores we record the direct sale of the products, typically handsets, as gross
revenue when we are the primary obligor in the arrangement and when title is passed and the products are accepted by the stores.

Impairment of Accounts Receivable

We maintain allowances for doubtful accounts for estimated losses that result from the inability of our customers to make required payments before January 1, 2011. We assess the probability of
collections of accounts receivable by examining the aging analysis of the outstanding receivables and assessing the value of the collateral provided by customers.

On January 1, 2011, we adopted the third-time revised Statement of Financial Accounting Standards No. 34, Financial Instruments: Recognition and Measurement. One of the main
revisions is that the impairment of receivables originated by us should be covered by No. 34. Accounts receivable are assessed for impairment at the end of each reporting period and considered to be impaired when there is objective evidence
that, as a result of one or more events that occurred after the initial recognition of the accounts receivable, the estimated future cash flows of the asset have been affected.

We implemented new measures starting from 2010 which have improved the collectability of our accounts receivable. These new procedures,
which include enhanced credit assessments, strengthened overall risk management and improvements in bill collection practices, have reduced our exposure to uncollected receivables. These improvements enabled us to refine our estimates, which led to
the reversal in the allowance for bad debt.

The amount of the impairment loss recognized is the difference between the asset
carrying amount and the present value of estimated future cash flows, after taking into account the related collateral and guarantees, discounted at the receivables original effective interest rate.

Estimated Useful Lives of Long-Lived Assets

A significant portion of our total assets consists of long-lived assets, primarily property, plant and equipment and definite-lived intangibles. We estimate the useful lives of property, plant and
equipment and other long-lived assets with finite lives in order to determine the period of time over which depreciation and amortization expense should be recorded. The useful lives are estimated at the time assets are acquired and are based on
historical experience with similar assets as well as the anticipated technological evolution or other environmental changes. If technological changes were to occur more rapidly than anticipated or in a different form than anticipated, the useful
lives assigned to these assets may need to be shortened, resulting in the recognition of increased depreciation and amortization in the relevant periods. Alternatively, technological obsolescence could result in a write-down in the value of the
assets to reflect impairment. We review these types of assets for impairment quarterly, or when events or circumstances indicate that the carrying amount may not be recoverable over the remaining life of an asset. In assessing impairments, we use
estimated cash flows that take into account managements estimates of future operations. We did not have a significant impairment loss of long-lived assets in 2011, but had NT$66 million impairment loss in 2010. In 2012, we determined that
partial land and telecommunication equipment were impaired and recognized an impairment loss of NT$1,505 million (US$51.8 million). In 2012, we also recognized impairment losses of NT$4.8 million (US$0.2 million), NT$35 million (US$1.2 million) and
NT$20 million (US$0.7 million) for intangible assets, idle assets and other assets, respectively.

Investments in Unconsolidated Companies

We hold investments in other companies that we account for under the equity method or cost method of accounting, depending on our ability
to exert significant influence over the investee company. The amounts for our equity method investments generally represent our cost of the initial investment adjusted for our share of the investee companys income or loss and any dividends
received. The amounts for our investments carried at cost where the securities are not publicly traded generally represent our cost of the initial investment less any adjustments we make when we determine that an investments net realizable
value is less than its carrying cost. Estimating the net realizable value of investments in privately held companies can be inherently subjective and may contribute to significant volatility in our reported results of operations.

We assess the impairment of investments accounted for using the equity method whenever triggering events or changes in circumstances
indicate that an investment may be impaired and carrying value may not be recoverable. We measure the impairment based on the projected future cash flow of the investees, the underlying assumptions for which had been formulated by such
investees internal management team, taking into account sales growth and capacity utilization.

The process of assessing
whether a particular cost method investments net realizable value is less than its carrying cost requires a significant amount of judgment. We periodically evaluate these long-term investments based on quoted market prices, if available, the
financial condition of the investee company, economic conditions in the industry and our intent and ability to hold the investment for a long period of time. If quoted market prices are not available, we estimate the fair value using the net asset
values as well as the financial condition of the investee company. This information may be based on information that we request from the investee companies and may not be subject to the same disclosure and audit requirements as required of
non-foreign private issuers, and as such, the reliability and accuracy of the information may vary. If we deem the fair value of an investment to be less than the book value based on the above factors, and the decline in value is deemed to be other
than temporary, we record the difference as impairment in the period of occurrence. In 2012, we recognized impairment losses of NT$176 million (US$6.1 million) for the investments classified as financial assets carried at cost due to adverse changes
in industry conditions and operating performance that was below expectations. Note 14 to our consolidated financial statements included elsewhere in this annual report sets forth the individual impairment loss of each investee.

Valuation of long-lived assets and intangible assets

We assess the impairment of long-lived assets and intangible assets whenever triggering events or changes in circumstances indicate that the asset may be impaired and carrying value may not be
recoverable. Indications we consider important which could trigger an impairment review include, but are not limited to, the following:



| |  |  | External sources of information:
| | - |  | --------------------------------



| |  |  | during the period, an assets market value has declined significantly more than would be expected as a result of the passage of time or normal
use.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | significant changes with an adverse effect on the entity have taken place during the period, or will take place in the near future, in the
technological, market, economic or legal environment in which the entity operates or in the market to which an asset is dedicated.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | market interest rates or other market rates of return on investments have increased during the period, and those increases are likely to affect the
discount rate used in calculating an assets value in use and decrease the assets recoverable amount materially.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the carrying amount of the net assets of the entity is more than its market capitalization.
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | Internal sources of information:
| | - |  | --------------------------------



| |  |  | evidence is available of obsolescence or physical damage of an asset.
| | - |  | ---------------------------------------------------------------------

##### Table of Contents

| |  |  | significant changes with an adverse effect on the entity have taken place during the period, or are expected to take place in the near future, in the
extent to which, or manner in which, an asset is used or is expected to be used.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | evidence is available from internal reporting that indicates that the economic performance of an asset is, or will be, worse than expected.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------

When an indication of impairment is identified for long-lived assets and intangible assets other than
goodwill, any excess of the carrying amount of an asset over its recoverable amount is recognized as a loss. If the recoverable amount increases in a subsequent period, the amount previously recognized as impairment would be reversed and recognized
as a gain. However, the adjusted amount may not exceed the carrying amount that would have been determined, as if no impairment loss had been recognized.

Goodwill represents the excess of the consideration paid for business acquisition over the fair value of identifiable net assets acquired. Goodwill is tested for impairment annually. If an event occurs or
circumstances change which indicates that the fair value of goodwill is below its carrying amount, an impairment loss is recognized. A subsequent reversal of such impairment loss is not allowed.

Pension Benefits

The amounts recognized in our consolidated financial statements related to defined benefit pension are determined on an actuarial basis
that utilizes several different assumptions in the calculation of such amounts. Significant assumptions used in determining our pension benefits are the discount rate, the expected long-term rate of return on plan assets, the rate of increase in
compensation levels, and the average remaining years of service for employees.

We use long-term historical actual return
information and estimate future long-term investment returns by reference to external sources to develop the expected long-term return on plan assets. The discount rate is assumed based on the rates available on high-quality fixed-income debt
instruments with the same period to maturity as the estimated period to maturity of the pension benefit. We assume the rate of increase in compensation levels and average remaining years of service based on historical data. Any changes in one or
more of these assumptions could impact our pension benefits.

For employees under defined contribution pension plans, pension
costs are recorded based on the actual contributions made to employees individual pension accounts during their service periods.

Accounting for Income Taxes

Deferred income taxes represent the effect of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the amounts recognized for income tax
purposes. We measure deferred tax assets and liabilities using statutory tax rates that, if changed, would result in either an increase or a decrease in the provision for income taxes in the period of change.

We record a valuation allowance to reduce our deferred tax assets to the amount of future tax benefit that is more likely than not to be
realized. While we have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, we cannot assure you that we would not need to increase the valuation allowance to
cover additional deferred tax assets that may not be realizable. Any increase in the valuation allowance could have a material adverse effect on our income tax provision and net income in the period in which such determination is made.

We had a valuation allowance of NT$109 million (US$3.8 million) on our deferred tax asset balance as of December 31, 2012. We do not
have a full valuation allowance on the deferred tax asset, as we believe these benefits will be partially realizable based on our projection of future operating income. If we experience a significant decrease in our future operating income, our
ability to realize the deferred tax assets could be negatively impacted, and thus an increase in the valuation allowance might be required.

Any tax credits arising from purchases of machinery, equipment and technology, research and
development expenditures, personnel training, and investments in important technology based enterprises are recognized using the flow through method. Adjustments of prior years tax liabilities are added to or deducted from the current
years tax provision. Under ROC GAAP, income taxes of 10% on undistributed earnings are recorded in the year of stockholders approval which is the year subsequent to the year the earnings are generated. Under U.S. GAAP, the 10% tax on
unappropriated earnings is accrued during the period the earnings arise and adjusted to the extent that distributions are approved by the stockholders in the following year.

Effective from January 1, 2007, we adopted a guidance prescribing the recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken
or expected to be taken in a tax return under U.S. GAAP. This guidance also provides guidance on derecognition, classification, interest and penalties, disclosure and transition. The evaluation of a tax position in accordance with this guidance is a
two-step process. The first step is recognition, where we evaluate whether an individual tax position has a likelihood of greater than 50% of being sustained upon examination based on the technical merits of the position, including resolution of any
related appeals or litigation processes. For tax positions that are currently estimated to have a less than 50% likelihood of being sustained, zero tax benefit is recorded. For tax positions that have met the recognition threshold in the first step,
we perform the second step of measuring the benefit to be recorded. The actual benefits ultimately realized may differ from the estimates. The adoption of this guidance did not have a material impact on our results of operation, financial position
and cash flows. We did not identify significant unrecognized tax benefits for each of the years ended December 31, 2010, 2011 and 2012. It is highly unlikely that we will incur any interests or penalties related to potential underpaid income
tax expenses.

Our Financial Reporting Obligations

Our ongoing financial reporting in our Form 20-F annual reports and interim financial reporting furnished to the SEC on Form 6-K had been based on U.S. GAAP through fiscal year 2007. Beginning with our
first quarter interim financial report furnished on Form 6-K and our Form 20-F annual report for fiscal year 2008, we prepared our financial statements under ROC GAAP, with reconciliations to U.S. GAAP.

Each of our operating segments is managed separately because each represents a strategic business unit
that serves a different market. We measure our segment performances mainly based on revenues and income before tax.

The year ended
December 31, 2012 compared with the year ended December 31, 2011

Revenues

Our revenues increased by 1.2% from NT$217.5 billion in 2011 to NT$220.1 billion (US$7.6 billion) in 2012. This increase was primarily due
to increase in revenues generated from mobile communications business sector.

Domestic fixed communications

Domestic fixed communications revenues comprised 36.5% and 34.3% of our revenues in 2011 and 2012, respectively. Our domestic fixed-line
revenues decreased by 4.9% from NT$79.4 billion in 2011 to NT$75.5 billion (US$2.6 billion) in 2012.

##### Table of Contents

Local telephone services. Our local telephone revenues decreased from NT$41.7 billion
in 2011 to NT$40.2 billion (US$1.4 billion) in 2012. This reflects a 7.7% decline in traffic volume from 15.6 billion minutes in 2011 to 14.4 billion minutes in 2012. The decline in traffic volume was primarily due to the traffic migration from
fixed-line services to mobile and internet telephone services. We expect this trend to continue as broadband and mobile services become more widely adopted in Taiwan.

Domestic long distance telephone services. Our domestic long distance telephone revenues decreased by 34.9% from NT$5.8 billion in 2011 to NT$3.8 billion (US$0.1 billion) in 2012. This decrease was
mainly due to domestic long distance call tariff reduction starting from 2012. The increase in traffic volume was primarily due to the tariff reduction. Our interconnection revenues also decreased primarily because the telecommunications operators
construct their own interconnection circuit.

Broadband access. The number of our ADSL customers decreased from
2.1 million in 2011 to 1.8 million in 2012 due to customer migration to our FTTx services. There was an increase in the number of FTTx customers from approximately 2.4 million in 2011 to approximately 2.7 million in 2012.
Broadband access revenue decreased from NT$20.4 billion for 2011 to NT$19.2 billion (US$0.7 billion) for 2012 mainly due to the approximate 20% tariff reduction in ADSL starting from 2012, and the NCCs mandated tariff reduction.

Domestic leased line. Our overall leased line tariffs have continued to be adversely affected by competition from other fixed-line
operators, as well as the continued migration of domestic leased line customers to broadband services. Domestic leased line revenue decreased from NT$5.7 billion for 2011 to NT$5.4 billion (US$0.2 billion) for 2012.

MOD. Our MOD revenues increased by 36.0% from NT$1.4 billion in 2011 to NT$2.0 billion (US$0.1 billion) in 2012. This increase was
due to the increases in the number of subscribers and in the average revenue per user.

Others. Other revenues
increased by 14.0% from NT$4.4 billion in 2011 to NT$4.9 billion (US$0.2 billion) in 2012. This increase was mainly due to an increase in corporate solution ICT business and the hot selling of high definition TV.

Mobile communications

Revenues from our mobile communications business segment comprised 42.8% and 45.8% of our revenues in 2011 and 2012, respectively.
Revenues from our mobile communications business segment increased by 8.4% from NT$93.0 billion in 2011 to NT$100.8 billion (US$3.5 billion) in 2012. This increase was principally due to the growth of mobile VAS revenue and handset sales revenue
offsetting the decline of mobile voice revenue over years. The growth of mobile voice traffic was mainly due to our promotional plans.

Mobile services. Revenues from our mobile services comprised 32.6% and 32.9% of our revenues in 2011 and 2012, respectively. Revenues from our mobile services increased by 2.2% from NT$70.9 billion
in 2011 to NT$72.5 billion (US$2.5 billion) in 2012 due to the growth of mobile VAS revenue from NT$15.2 billion in 2011 to NT$20.4 billion (US$0.7 billion) in 2012, which offset the decline of mobile voice revenue.

Sales of mobile handsets and data cards. Revenues from our sales of mobile handsets and data cards comprised 10.1% and 12.8% of
our revenues in 2011 and 2012, respectively. Revenues from our sales of mobile handsets and data cards increased by 28.3% from NT$22.0 billion in 2011 to NT$28.2 billion (US$1.0 billion) in 2012. This increase was principally due to the strong sales
of mobile smart phones.

Internet

Internet revenues comprised 11.4% and 11.2% of our revenues in 2011 and 2012, respectively. Our revenues attributable to our internet business remained flat at NT$24.8 billion (US$0.9 billion) in 2011 and
2012. The increase in the internet VAS revenue was offset by the tariff reduction for the HiNet ISP service along with the broadband access tariff reduction. As of December 31, 2012, approximately 82.8% of our broadband customers were also
HiNet subscribers, using HiNet as their ISP.

International fixed communications

As a percentage of our revenue, international fixed communications revenues remained flat at 7.0% in 2011 and 2012. Our international
fixed communications revenues increased by 0.7% from NT$15.2 billion in 2011 to NT$15.3 billion (US$0.5 billion) in 2012. This increase was mainly due to the increase in revenues from our international leased line services and international data
services.

International long distance telephone services. Our international long distance telephone revenues decreased
by 2.9% from NT$12.4 billion in 2011 to NT$12.1 billion (US$0.4 billion) in 2012 due to market competition.

International
leased line and international data services. Our international leased line and international data revenues increased by 12.1% from NT$2.1 billion in 2011 to NT$2.5 billion (US$0.1 billion) in 2012. The increase was mainly because of the overseas
market expansion and the increased demand of multinational corporations.

Others

Other revenues comprised 2.3% and 1.7% of our revenues in 2011 and 2012, respectively. Our other revenues decreased by 27.1% from NT$5.1
billion in 2011 to NT$3.7 billion (US$0.1 billion) in 2012. The decrease was mainly due to lower property sales by our subsidiary, Light Era Development Co., Ltd., in 2012 compared with 2011.

Operating Costs and Expenses

Our operating costs and expenses
increased by 5.4% from NT$162.4 billion in 2011 to NT$171.2 billion (US$5.9 billion) in 2012. This increase was primarily due to an increase in costs of handsets sold. As a percentage of revenues, operating costs and expenses increased from 74.7% in
2011 to 77.8% in 2012.

Operating Costs

Operating costs include depreciation and amortization expense, personnel expenses, cost of goods sold, interconnection and service expense, costs of materials and maintenance and spectrum usage and
license fees.

Our operating costs increased by 7.4% from NT$131.5 billion in 2011 to NT$141.2 billion (US$4.9 billion) in
2012. This increase was primarily a result of an increase of NT$8.5 billion (US$0.3 billion) in cost of goods sold due to an increase in the sales of smart phones, an increase of NT$0.5 billion (US$0.02 billion) in rental expenses, an increase of
NT$0.3 billion (US$0.01 billion) in maintenance and material expenses in order to support our broadband and mobile internet service build-out, an increase of NT0.3 billion (US$0.01 billion) in the electricity expense due to the increase in
electricity tariff, and a NT$0.3 billion (US$0.01 billion) increase in ICT costs due to the growth in ICT business. These increases were partially offset by a decrease of NT$0.4 billion (US$0.01 billion) in personnel expenses mainly due to the
decrease in amount of bonuses paid.

Marketing

Our marketing expenses, which include personnel expenses, expenses relating to advertising and marketing-related activities and provision for bad debt, decreased by 3.9% from NT$23.2 billion in 2011 to
NT$22.3 billion (US$0.8 billion) in 2012. This decrease was primarily a result of a NT$1.5 billion (US$0.05 billion) reversal of bad debts allowance, which was partially offset by an increase of NT$0.5 billion (US$0.02 billion) in expenses relating
to personnel and marketing-related activities from our subsidiary, Senao. See Critical Accounting PoliciesImpairment of Accounts Receivable for a discussion of our policy for bad debts allowance.

General and administrative

Our general and administrative expenses decreased by 4.8% from NT$4.2 billion in 2011 to NT$4.0 billion (US$0.1 billion) in 2012. This decrease was primarily a result of a NT$0.1 billion (US$0.01 billion)
decrease due to deconsolidation of a subsidiary after we lost control over it in June 2011, and a NT$0.1 billion (US$0.01 billion) decrease in bonus.

Research and development

Our research and development expenses increased
by 5.7% from NT$3.5 billion in 2011 to NT$3.7 billion (US$0.1 billion) in 2012. This increase was principally a result of an increase in the number of research and development employees we hired in 2012.

Domestic fixed communications

Our domestic fixed communications costs and expenses decreased by 0.4% from NT$76.7 billion in 2011 to NT$76.4 billion (US$2.6 billion) in 2012, primarily due to a NT$0.7 billion (US$0.02 billion)
decrease in bonus, which was partially offset by a NT$0.4 billion (US$0.01 billion) increase in corporate solution services and ICT costs.

Mobile communications

Our mobile communications operating costs and expenses increased by 12.6% from NT$72.3 billion in 2011 to NT$81.4 billion (US$2.8 billion)
in 2012. This increase was primarily due to an increase of NT$7.6 billion (US$0.3 billion) in cost of handsets sold, and a NT$1.9 billion (US$0.1 billion) increase in leased line and internet access expenses resulting from the increasing leased
lines and higher speed rate to support our mobile internet services.

Internet

Our internet operating costs and expenses increased by 10.5% from NT$17.2 billion in 2011 to NT$19.0 billion (US$0.7 billion) in 2012.
This increase was primarily due to a NT$0.8 billion (US$0.03 billion) increase in leased line expenses to promote the broadband access speed, a NT$0.4 billion (US$0.01 billion) increase in depreciation and amortization expenses due to increasing
cloud computing related facilities, and a NT$0.2 billion (US$0.01 billion) increase in corporate solution services and ICT costs.

International fixed communications

Our international fixed communications costs and expenses increased by 2.5% from NT$15.8 billion in 2011 to NT$16.2 billion (US$0.6 billion) in 2012. The increase was primarily due to an increase of
NT$0.5 billion (US$0.02 billion) in settlement payments for international long distance calls.

Others

The costs and expenses from our other business decreased by 1.3% from NT$8.0 billion in 2011 to NT$7.9 billion (US$0.3 billion) in 2012. The decrease was primarily due to lower property sales by our
subsidiary, Light Era Development Co., Ltd., in 2012 compared to 2011, which was partially offset by the increase of ICT costs from our subsidiary, Chunghwa System Integration Co., Ltd.

Income from Operations and Operating Margin

As a result of the
foregoing, our income from operations decreased by 11.3% from NT$55.1 billion in 2011 to NT$48.9 billion (US$1.7 billion) in 2012. Our operating margin decreased from 25.3% in 2011 to 22.2% in 2012.

The following table sets forth certain information regarding our operating income by business segment for the periods indicated.

As a result of the foregoing, segment income before tax for our domestic fixed communications business
decreased by 18.9% from NT$18.5 billion in 2011 to NT$15.0 billion (US$0.5 billion) in 2012; segment income before tax for our mobile communications business decreased by 7.2% from NT$27.8 billion in 2011 to NT$25.8 billion (US$0.9 billion) in 2012;
segment income before tax for our internet business decreased by 10.4% from NT$9.6 billion in 2011 to NT$8.6 billion (US$0.3 billion) in 2012; segment income before tax for our international fixed communications business decreased by 35.0% from
NT$2.0 billion in 2011 to NT$1.3 billion (US$0.04 billion) in 2012; and segment loss for our others business segment increased by 50.0% from NT$1.2 billion in 2011 to NT$1.8 billion (US$0.1 billion) in 2012.

Other Income, Net

Our other income, net decreased from NT$1.6 billion in 2011 to the net loss NT$17.0 million (US$0.6 million) in 2012. This decrease was
primarily due to an increase of impairment loss of NT$1.6 billion (US$0.1 billion) on financial assets, property, plant, and equipment, intangible assets, idle assets and other assets. Please refer to Item 3. Key InformationD. Risk
Factors for further description. This decrease was also due to the smaller decrease of gain on disposal of property, plant and equipment of NT$0.3 billion (US$10.3 million), which was partially offset by a higher increase in earnings of equity
method investees of NT$0.2 billion (US$5.7 million).

Income Tax

Our income tax was NT$8.6 billion in 2011, compared to NT$7.9 billion (US$0.3 billion) in 2012. Our effective tax rate was 15.2% in 2011 and 16.1% in 2012. The increase of our effective tax rate from 2011
to 2012 was primarily due to fewer tax incentives available under new regulations. We will no longer receive tax credits for new investments in automation, employee training expenditures incurred, and equipment and technology purchased. Please refer
to Item 5. Operating and Financial Review and ProspectsTaxation for a discussion of the change in tax incentives.

Net
Income

As a result of the foregoing, our net income attributable to stockholders of the parent decreased by 15.3% from
NT$47.1 billion in 2011 to NT$39.9 billion (US$1.4 billion) in 2012. Our net margin was 21.6% in 2011 and 18.1% in 2012.

The year ended
December 31, 2011 compared with the year ended December 31, 2010

Revenues

Our revenues increased by 7.4% from NT$202.4 billion in 2010 to NT$217.5 billion in 2011. This increase was primarily due to increase in
revenues generated from domestic fixed communications, mobile communications, and other business sectors.

Domestic fixed communications

Domestic fixed communications revenues comprised 34.9% and 36.5% of our revenues in 2010 and 2011, respectively. Our
domestic fixed-line revenues increased by 12.3% from NT$70.7 billion in 2010 to NT$79.4 billion in 2011.

Local telephone
services. Our local telephone revenues increased from NT$32.3 billion in 2010 to NT$41.7 billion in 2011. This reflects the shift in policies for collecting the tariffs for fixed-to-mobile calls from mobile service providers to fixed
communications service providers since January 1, 2011, which gave our fixed communications business the right to set and collect the tariffs for fixed-line-to-mobile phone calls. Traffic volume increased from 13.7 billion minutes in 2010 to
15.6 billion minutes in 2011. We primarily attribute the increase in traffic volume to the inclusion of fixed-line-to-mobile calls under this category as a result of the NCCs change in policy for collecting the tariffs from
fixed-line-to-mobile calls starting from 2011. For the same reason, our local interconnection revenues decreased by NT$1.0 billion from NT$2.4 billion in 2010 to NT$1.4 billion in 2011 because fixed communications service providers received less
interconnection charges from mobile service providers.

Domestic long distance telephone services. Our domestic long
distance telephone revenues decreased by 12.9% from NT$6.6 billion in 2010 to NT$5.8 billion in 2011. This decrease was mainly due to a decrease in traffic volume from 3.4 billion minutes in 2010 to 3.2 billion minutes in 2011. The decrease in
traffic volume was primarily due to the continued traffic migration from fixed-line services to mobile services and VoIP.

Broadband access. The number of our ADSL customers decreased from 2.3 million in 2010 to 2.1 million in 2011 due to
customer migration to our FTTx services. There was an increase in the number of FTTx customers from approximately 2.0 million in 2010 to approximately 2.4 million in 2011. Broadband access revenue increased from NT$20.3 billion for 2010 to
NT$20.4 billion for 2011.

Domestic leased line. While demand for higher speed leased lines continues to increase, our
overall leased line tariffs have continued to be adversely affected by competition from other fixed-line operators, as well as the continued migration of domestic leased line customers to broadband services. Domestic leased line revenue decreased
from NT$6.1 billion for 2010 to NT$5.7 billion for 2011.

billion in 2011. This increase was mainly due to an increase in the number of subscribers.

Others. Other revenues
increased by 0.4% from NT$4.3 billion in 2010 to NT$4.4 billion in 2011. This increase was mainly due to an increase in corporate solution ICT business.

Mobile communications

Revenues from our mobile communications business
segment comprised 44.0% and 42.8% of our revenues in 2010 and 2011, respectively. Revenues from our mobile communications business segment increased by 4.4 % from NT$89.0 billion in 2010 to NT$93.0 billion in 2011. This increase was principally
due to the growth of mobile VAS revenue and handset sales revenue offsetting the decline of mobile voice revenue since 2008. The growth of mobile voice traffic due to the general recovery of the economy in the ROC was partially offset by the
mandatory tariff reduction and the impact from the change in policy for collecting the tariffs for fixed-line-to-mobile calls from mobile service providers to fixed communications service providers since January 1, 2011, which gave our fixed
communications business the right to set and collect the tariffs for fixed-line-to-mobile phone calls.

Mobile
services. Revenues from our mobile services comprised 36.1% and 32.6% of our revenues in 2010 and 2011, respectively. Revenues from our mobile services decreased by 3% from NT$73.1 billion in 2010 to NT$70.9 billion in 2011 due to the decline of
mobile voice revenue as a result of the change in policy for collecting the tariffs for fixed-line-to-mobile phone calls from mobile service providers to fixed communications service providers, and the mandatory tariff reduction, which was partially
offset by the growth of mobile VAS revenue from NT$11.1 billion in 2010 to NT$15.2 billion in 2011.

Sales of mobile
handsets and data cards. Revenues from our sales of mobile handsets and data cards comprised 7.9% and 10.1% of our revenues in 2010 and 2011, respectively. Revenues from our sales of mobile handsets and data cards increased by 38.4% from NT$15.9
billion in 2010 to NT$22.0 billion in 2011. This increase was principally due to the strong sales of mobile smart phones and the general recovery of the economy in the ROC

Internet

Internet revenues comprised 12.1% and 11.4% of our revenues in
2010 and 2011, respectively. Our revenues attributable to our internet business increased by 1.4 % from NT$24.5 billion in 2010 to NT$24.8 billion in 2011. The increase was mainly due to a 3% increase in the number of our total HiNet broadband
subscribers from approximately 3.6 million as of December 31, 2010 to approximately 3.7 million as of December 31, 2011. Our HiNet subscribers remained at approximately 4.1 and 4.2 million subscribers as of December 31,
2010 and 2011, respectively. As of December 31, 2011, approximately 82% of our broadband access customers were also HiNet subscribers, using HiNet as their ISP.

International fixed communications

International fixed communications
revenues comprised 7.7% and 7.0% of our revenues in 2010 and 2011, respectively. Our international fixed communications revenues decreased by 2% from NT$15.5 billion in 2010 to NT$15.2 billion in 2011. This decrease was mainly due to the decrease in
international long distance service revenue as a result of intensified market competition.

International long distance
telephone services. Our international long distance telephone revenues decreased by 3.4% from NT$12.9 billion in 2010 to NT$12.4 billion in 2011 because of the decline in traffic volumes as a result of intensified market competition.

International leased line and international data services. Our international leased line and international data revenues increased
by 6% from NT$2.0 billion in 2010 to NT$2.1 billion in 2011. The increase was mainly because of the overseas market expansion and the increased demand of multinational corporations.

due to higher property sales by our subsidiary, Light Era Development Co., Ltd.

Operating Costs and Expenses

Our operating costs and expenses increased by 12.0% from NT$145.0 billion in 2010 to NT$162.4 billion in 2011. This increase was primarily
due to the higher cost of handsets sold, interconnection costs and transition fees resulting from the change in policy for collecting the tariffs of fixed-line-to-mobile phone calls.

Operating costs include depreciation and amortization
expense, personnel expenses, cost of goods sold, interconnection and service expense, costs of materials and maintenance and spectrum usage and license fees.

Our operating costs increased by 14.0% from NT$115.3 billion in 2010 to NT$131.5 billion in 2011. This increase was principally a result of an increase of NT$8.1 billion in cost of goods sold, an increase
of NT$7.1 billion in interconnection and service expenses mainly due to the change in policy for collecting the tariffs of fixed-line-to-mobile phone calls, an increase of NT$1.0 billion in maintenance and material expenses due to expansion of
broadband facilities, a NT$1.0 billion increase in corporate solution ICT costs due to the increase in revenue. These increases were partially offset by a decrease of NT$1.8 billion in depreciation.

Our marketing
expenses, which include personnel expenses, expenses relating to advertising and marketing-related activities and provision for bad debt increased by 3.1% from NT$22.5 billion in 2010 to NT$23.2 billion in 2011. This increase was principally a
result of a NT$0.3 billion increase in salary expenses due to headcount growth, and NT$0.2 billion in expenses relating to human resource outsourcing services for the sales division.

General and administrative

Our general and administrative expenses
increased by 4.2% from NT$4.0 billion in 2010 to NT$4.2 billion in 2011. This increase was principally a result of new business in mobile industry in Mainland China and an increase in personnel expenses mainly due to salary increases, additional
employees and bonuses.

Research and development

Domestic fixed communications

Our domestic fixed communications costs and expenses increased by 14.5% from NT$67.0 billion in 2010 to NT$76.7 billion in 2011, primarily
due to an increase of NT$9.7 billion in interconnection and service expenses mainly due to the change in policy for collecting the tariffs of fixed-line-to-mobile phone calls. Since we are the market leader of the local call services, in addition to
the interconnection fees, we are required to pay transition fees to the mobile operators for a period of six years.

Mobile communications

Our mobile communications operating costs and expenses increased by 16.4% from NT$62.1 billion in 2010 to NT$72.3 billion
in 2011. This increase was primarily due to an increase of NT$7.9 billion in cost of handsets sold and an increase of NT$1.6 billion in leased line and internet access expenses.

Internet

Our internet operating costs and expenses increased by 9.1% from
NT$15.8 billion in 2010 to NT$17.2 billion in 2011. This increase was primarily due to an increase of NT$0.8 billion in leased line expenses for broadband services and an increase of NT$0.4 billion in corporate solution services and ICT costs.

International fixed communications

Our international fixed communications costs and expenses increased by 9.2% from NT$14.5 billion in 2010 to NT$15.8 billion in 2011. The increase was primarily due to an increase of NT$0.9 billion in
international interconnection expenses.

Others

The costs and expenses from our other business increased by 32.0 % from NT$6.1 billion in 2010 to NT$8.0 billion in 2011. The increase was primarily due to an increase of NT$1.4 billion in
construction costs and an increase of NT$0.5 billion in research and development expense.

Income from operations and Operating Margin

As a result of the foregoing, our income from operations decreased by 4.0% from NT$57.4 billion in 2010 to NT$55.1
billion in 2011. Our operating margin decreased from 28.3% in 2010 to 25.3% in 2011.

As a result of the foregoing, the segment income before tax for our domestic fixed communications business increased by 2.4% from NT$18.1 billion in 2010 to NT$18.5 billion in 2011; segment income before
tax for our mobile communications business decreased by 5.1% from NT$29.3 billion in 2010 to NT$27.8 billion in 2011; segment income before tax for our internet business decreased by 2.8% from NT$9.8 billion in 2010 to NT$9.6 billion in 2011;
segment income before tax for our international fixed communications business decreased by 23.1% from NT$2.7 billion in 2010 to NT$2.0 billion in 2011; and segment loss for our others business segment decreased by 43.7% from NT$2.2 billion in 2010
to NT$1.2 billion in 2011.

Other Income, Net

Our other income, net increased by 402.8% from NT$0.3 billion in 2010 to NT$1.6 billion in 2011. This increase was primarily due to a NT$0.5 billion increase in net gain on disposal of property, plant and
equipment, a NT$0.2 billion increase in equity in earnings of equity method investees, a NT$0.3 billion increase in net interest income, and a NT$0.2 billion decrease in net loss on valuation and disposal of financial instruments.

Income Tax

Our
income tax was NT$9.1 billion in 2010, compared to NT$8.6 billion in 2011. Our effective tax rate was 15.8% in 2010 and 15.2% in 2011, primarily due to lower income from operations. Please refer to Item 5. Operating and Financial Review and
ProspectsTaxation for a discussion of the change in tax rate.

Net Income

As a result of the foregoing, our net income attributable to stockholders of the parent decreased by 1.1% from NT$47.6 billion in 2010 to
NT$47.1 billion in 2011. Our net margin was 23.5% in 2010 and 21.6 % in 2011.

Our primary source of liquidity is cash flow from operations, which represents operating profit adjusted
for non-cash items, primarily depreciation and amortization and changes in current assets and liabilities. We believe that our working capital is sufficient to meet our present cash flow requirements.

##### Table of Contents

In 2012, we generated NT$67.5 billion (US$2.3 billion) net cash from operating activities as
compared to NT$75.3 billion in 2011. The decrease was primarily due to a NT$7.1 billion (US$0.2 billion) decrease in consolidated net income and the exemption of deposits that we collect from specific mobile subscribers in advance for bundling
subsidized mobile handsets with service plans.

In 2011, we generated NT$75.3 billion net cash from operating activities as
compared to NT$84.8 billion in 2010. The decrease was primarily due to a NT$6.0 billion decrease in cash flow from accounts receivable because starting from 2011, we brought our billing period for monthly fees in line with that for connection
charges, and due to a NT$2.3 billion decrease in income from operations owing to the increased operating cash outflow which outnumbered the revenue in 2011.

Historically, net cash from operating activities has been sufficient to cover our capital expenditures, including ongoing expansion and modernization of our networks.

In 2012, net cash used in investing activities was NT$38.9 billion (US$1.3 billion), increasing by 5.8 million from NT$33.1 billion
in 2011. The change was primarily due to the increase in acquisition of property, plant and equipment.

In 2011, net cash used
in investing activities was NT$33.1 billion, an increase from NT$17.4 billion in 2010. The change was primarily due to the decrease in cash flow from disposal of available-for-sale financial instruments.

In 2012, our net cash used in financing activities totaled NT$42.8 billion (US$1.5 billion), which mainly included NT$42.4 billion
(US$1.5 billion) of payment of dividends during that period.

In 2011, our net cash used in financing activities totaled
NT$65.7 billion, which mainly reflected NT$42.9 billion of payment of dividends during that period and NT$19.4 billion of cash distribution to our stockholders for a capital reduction plan.

Capital Resources

We have historically financed our capital expenditure
requirements with our cash flows from operations. In future years, we expect to have capital expenditure requirements for the ongoing expansion and upgrade of our networks, including 3G/HSPA/HSPA+/Dual cell HSPA+, FTTx, Wi-Fi/femtocell and
service platforms, and future construction of LTE to migrate mobile and data service customers to higher contribution platforms. We also expect to make dividend payments on an ongoing basis. See Item 8. Financial InformationA.
Consolidated Statements and Other Financial Information. Furthermore, we may require working capital from time to time to finance purchases of materials for our maintenance and other overhead expenses. We expect to primarily rely on cash
generated from operations and, to a lesser extent, loans from commercial banks to meet our planned capital expenditures, make our planned dividend payments, repay debts and fulfill other commitments over the next twelve months.

As of December 31, 2012, our primary source of liquidity was NT$53.2 billion (US$1.8 billion) in cash and cash equivalents.

As of December 31, 2012, our subsidiary, Chief Telecom, had short-term unsecured loans in the amount of NT$40 million
(US$1.4 million) with interest rates ranging from 1.25% to 1.27%. As of December 31, 2012, Chief Telecom had long-term unsecured loans in the amount of NT$8 million (US$0.3 million) at an interest rate at 2.01% and due in 2013.

As of December 31, 2012, our subsidiary, Light Era Development Co., Ltd. had long-term secured loans in the amount of NT$2.1 billion
(US$70.6 million) with interest rates ranging from 1.13% to 2.10%, with NT$0.3 billion due in 2014, NT$1.4 billion due in 2015, and NT$0.4 billion due in 2017.

As of December 31, 2012, our subsidiary Chunghwa Precision Test Technology Co., Ltd.
had a short-term unsecured loan of NT$4 million (US$0.1 million) at an interest rate at 1.53%.

As of December 31, 2012,
our subsidiary Chunghwa Sochamp Technology Inc. had short-term unsecured loans of NT$67 million (US$2.3 million) at interest rates ranging from 1.38% to 2.40%.

As part of the governments effort to upgrade the existing telecommunication infrastructure, we and other public utility companies were required by the ROC government to contribute a total of NT$1.0
billion to a Piping Fund, administered by the Taipei City Government. This fund is used to finance various telecommunications infrastructure projects. We accounted for the contribution as other monetary assets on our consolidated balance sheets.

Note 29 to our consolidated financial statements included elsewhere in this annual report provides a description of the
assets are pledged as collateral for long-term bank loans and contract deposits.

Capital Expenditures

Substantially all of our capital expenditures in 2010, 2011 and 2012 were made for operations in the Republic of China. We have financed
our capital expenditures using cash flow from operations and bank loans. The following table sets forth a summary of our capital expenditures for the periods indicated.

We expect our total capital expenditures to be approximately NT$37.2 billion in 2013. In future periods,
we expect our total capital expenditures to rise due to the launch of new businesses, FTTx network expansion, access bandwidth enhancement, service platforms, cloud computing, including cloud data center construction, 3G/HSPA/HSPA+/Dual cell
HSPA+ mobile network expansion and submarine cables. We expect to finance these capital expenditures with our cash flows from operations and bank loans.

We do not believe that inflation in Taiwan has had a material impact on our results of operations in 2010, 2011 or 2012.

Recent Accounting Pronouncements

Transition to IFRS in 2013

See Item 3. Key InformationD. Risk FactorsRisks Relating to Our Company and the Taiwan Telecommunications
Industry. While we have adopted Taiwan IFRS for ROC reporting purposes, we plan to adopt IFRS for certain filings with the SEC, including our annual reports on Form 20-F for the year ending December 31, 2013 and thereafter. Following our
adoption of IFRS for SEC filing purposes, we will no longer be required to reconcile our consolidated financial statements with U.S. GAAP.

The significant differences between Taiwan IFRS and ROC GAAP that are relevant to us were disclosed in our 2012 full year financial reports prepared in accordance with ROC GAAP, which is available on our
website http://www.cht.com.tw. The information contained on our website does not form a part of this annual report.

Taiwan
IFRS differs from IFRS in certain significant respects, including to the extent that any new or amended standards or interpretations applicable under IFRS may not be timely endorsed by the FSC. For example, as of the date of this annual report, the
FSC has not endorsed any accounting pronouncements issued by the International Accounting Standards Board after January 1, 2011. Therefore, these pronouncements will not be applicable to Taiwan IFRS until endorsed by the FSC. Some of the major
differences between IFRS and Taiwan IFRS that are relevant to us as of the date of this annual report are set forth below.



| |  |  | The income taxes on undistributed earnings should be recognized at the year of earnings under IFRS, while it should be recognized at the
year of distribution under Taiwan IFRS.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | According to the laws and regulations applicable to state-owned enterprises in Taiwan, we recorded revenue from fixed-line service at the time the
service was performed. Upon incorporation, net assets greater than capital stock was credited as additional paid-in capital. Part of our additional paid-in capital was from unearned revenues from fixed-line services as of that date. Under IFRS,
following the revenue recognition guidance, the above service revenue should be treated as deferred income and recognized over the time when the service is continuously provided. Therefore, upon our first adoption of IFRS, we should retrospectively
decrease additional paid-in capital while increase retained earnings on the transition date of January 1, 2012. There is no difference in the recognition of unearned revenues or deferred income between IFRS and Taiwan IFRS. However, according
to the guidance released by the Taiwan Stock Exchange Corporation, or TWSE, in March 2012, which is a part of Taiwan IFRS, the additional paid-in capital under ROC GAAP that is not specifically promulgated under Taiwan IFRS should not be adjusted on
the transition date of January 1, 2012. Therefore, we retain such additional paid-in capital under Taiwan IFRS.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

It is difficult for us to evaluate the precise impact of the adoption of Taiwan IFRS and IFRS on our financial reporting generally, or on our financial statements for the year ending December 31,
2013 or the year ended December 31, 2012, because the FSC may issue new rules governing the adoption of Taiwan IFRS and as other laws and regulations may be amended with the adoption of Taiwan IFRS.

Upon our first adoption of Taiwan IFRS, we are required to apply Taiwan IFRS retrospectively unless otherwise exempted from certain
applications and to present the opening balance sheet on the transition date of January 1, 2012 with adjusted opening balances prepared under Taiwan IFRS. Any transactions after the transition date are accounted for in accordance with Taiwan
IFRS. Consequently, our consolidated financial statements for the year ended December 31, 2012 to be included in our annual report for the year ended December 31, 2013 may differ materially from those included in this annual report, even
though they relate to the same fiscal year. Similarly, the selected comparison financial information to be included in our quarterly earnings releases in 2013 may differ materially from those released historically.

Other recent accounting pronouncements

In May 2011, the Financial Accounting Standards Board (FASB) issued an accounting update to amend the fair value measurement guidance and
include some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The standard is effective for us for the year ended
December 31, 2012. We have included these new disclosure, as applicable, in note 35 to our consolidated financial statements included elsewhere in this annual report.

In June and December 2011, the FASB issued accounting updates to eliminate the current option to report other comprehensive income and its components in the statement of stockholders equity.
Instead, an entity will be required to present items of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements. The new requirements do not change which components of comprehensive
income are recognized in net income or other comprehensive income, or when an item of other comprehensive income must be reclassified to net income. The standard is effective for us for the year ended December 31, 2012. We have reported other
comprehensive income and its components in two separate but consecutive statements and the adoption did not have an impact on its results of operations, financial position or cash flows.

In September 2011, the FASB issued an accounting update, which is intended to reduce the cost and complexity of the annual goodwill
impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. Specifically, an entity has the option to first assess qualitative factors to determine
whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the
quantitative impairment test is required. Otherwise, no further testing is required. This standard is effective for us for the year ended December 31, 2012. The adoption of this guidance did not have a material impact on our results of
operations, financial position or cash flows.

In December 2011, the FASB issued an accounting update, which creates new
disclosure requirements regarding the nature of an entitys rights of setoff and related arrangements associated with its financial instruments and derivative instruments. Certain disclosures of the amounts of certain instruments subject to
enforceable master netting arrangements or similar agreements would be required, irrespective of whether the entity has elected to offset those instruments in the statement of financial position. The disclosure requirements are effective for annual
reporting periods beginning on or after January 1, 2013 with retrospective application required. Since we adopted IFRS for our fiscal year 2013, we will no longer adopt this standard.

In February 2013, the FASB issued an accounting update requiring entities to present information about significant items reclassified out
of accumulated other comprehensive income (loss) by component either on the face of the statement where net income is presented or as a separate disclosure in the notes to the financial statements. This standard is effective for the companies for
the year ending December 31, 2013. Since we adopted IFRS for our fiscal year 2013, we will no longer adopt this standard.

U.S. GAAP
Reconciliation

Our consolidated financial statements are prepared in accordance with ROC GAAP, which differ in certain
material respects from U.S. GAAP. The following table sets forth a comparison of our net income and stockholders equity in accordance with ROC GAAP and U.S. GAAP as of and for the periods indicated.

As of December 31, 2012, we had remaining commitments under non-cancelable contracts with various parties, including acquisition of
lands and buildings of NT$30.9 million (US$1.1 million), acquisition of telecommunications equipment of NT$25.8 billion (US$889.5 million), unused letters of credit of NT$150.0 million (US$5.2 million) and contracts for printing bills, envelopes and
marketing gifts of NT$17.8 million (US$0.6 million).

G. Foreign Exchange

Our revenues and costs and expenses are largely denominated in NT dollars. Our principal expenses denominated in foreign currencies are
capital expenditures on telecommunications equipment and settlement payments for the use of networks of carriers in foreign countries for outgoing international calls. Settlement receipts have been a principal source of foreign currency for us.
While future fluctuations of the NT dollar against foreign currencies could impact our financial condition and results of operations, we have not yet been materially affected in the past.

We do not have any service contracts with any directors providing for any benefits upon termination of
employment.

C. Board Practices

Thirteen directors and three supervisors were elected in 2010 for three-year terms. One of the directors designated by MOTC, Shen-Ching Chen, resigned in July 2011 and MOTC has not designated a new
director yet. Therefore we currently have 12 directors and three supervisors. Pursuant to the ROC Company Act, the directors may be removed from office at any time by a resolution adopted at a stockholders meeting. The chairman of our board of
directors is elected by our directors. Our chairman presides at all meetings of our board of directors and also has the authority to act as our representative. We have not entered into any contract with any of our directors and supervisors by which
our directors or supervisors are expected to receive benefits upon termination of their employment. Under the Article 12 of our articles of incorporation amended on June 22, 2012, our supervisors will be replaced by an audit committee, which
should be composed entirely of independent directors, starting from the 7th session of board of directors in 2013 annual general stockholders meeting, pursuant to Paragraph 1, Article 14-4 of the Securities and Exchange Act. We will no longer
have supervisors after the beginning of our 7th session of board of directors.

Our articles of incorporation provides for a
board of directors consisting of seven to fifteen members. Pursuant to the ROC Securities and Exchange Act, as amended in January 2006, the ROC Financial Supervisory Commission on May 28, 2006 published a rule requiring listed
non-financial-institution companies with paid-in capital exceeding NT$50 billion to appoint independent directors to serve on their board of directors in accordance with the Act. The term independent director may have a different meaning
when used in Taiwan than in other jurisdictions. The number of independent directors shall be not less than one-fifth of the total number of directors and not less than two in number. Pursuant to both the ROC Company Act and the ROC Securities and
Exchange Act, Article 12 Clause 1 of our articles of incorporation provides for the election of, starting from the fifth stockholders meeting, at least three independent directors out of the 7-to-15-member board. We have used a nominating
process, with the stockholders choosing the independent directors from the list of nominees. Accordingly, we have elected three independent directors in the annual general meeting on June 18, 2010. With respect to certain material decisions to
be made by our company as specified in the ROC Securities and Exchange Act, including the adoption or amendment to our internal control system, material loans or guarantees, the issuance of equity-type securities, matters in which directors and
supervisors have personal interests, the appointment and discharge of auditors, approval of financial reports, the appointment and discharge of financial, accounting or internal auditing officers and other matters prescribed by the ROC Financial
Supervisory Commission, the dissenting opinion or qualified opinion of an independent director is required to be noted in the minutes of the board of directors meeting.

Our audit committee was established in September 2004 in accordance with the rules set forth in the NYSE Listed Company Manual, and was comprised of our three independent directors: Chung-Yu Wang and
Zse-Hong Tsai and Chung-Fern Wu. See Item 16G. Corporate GovernanceAudit Committee. Starting from the date of the annual general meeting in June 2013, we will establish a new audit committee that replaces our supervisors and our
old audit committee in accordance with Paragraph 1, Article 14-4 of the ROC Securities and Exchange Act and our articles of incorporation amended on June 22, 2012, and as a result, we will simultaneously comply with the relevant rules of the
NYSE Listed Company Manual and the relevant rules and regulations in the ROC. Therefore, we will no longer have supervisors after the beginning of our 7th session of board of directors. In addition, the number of members, or independent directors,
in the audit committee, will increase from three to five according to the resolution of our board meeting.

##### Table of Contents

Until replacing our supervisors with our new audit committee after our annual general
meeting of shareholders in June 2013, we will still have three supervisors that were elected during the annual general meeting of shareholders in 2010. In accordance with the ROC Company Act, our supervisors are elected by our stockholders and may
not concurrently serve as our directors, executive officers or other staff members. The term of office for our supervisors is three years and their term may be renewed for any number of consecutive terms. Supervisors duties and powers include,
but are not limited to, supervision of our business operations, investigation of our financial condition, inspection of corporate records, verification of statements prepared by the board of directors prior to the annual general stockholders
meeting, calling of and giving reports at stockholders meetings, representation of us in negotiations with our directors and giving notification, when appropriate, to the board of directors to cease acting in contravention of applicable law or
regulations, our articles of incorporation or the resolutions adopted by our stockholders. The supervisors may be also removed from office at any time by a resolution adopted at a stockholders meeting. We will no longer have any supervisors
after our annual general meeting of shareholders in June 2013 when our new audit committee replaces our old audit committee and supervisors.

Under the ROC Company Act, a person may serve as our director or supervisor in his personal capacity or as the representative of another legal entity. A director or supervisor who serves as the
representative of a legal entity may be removed or replaced at any time at the discretion of that legal entity, and the replacement director or supervisor may serve the remainder of the term of office of the replaced director or supervisor. Except
for our three independent directors, all of our directors are representatives of the Ministry of Transportation and Communications. Our current supervisors consist of one representative from the Executive Yuans National Development Foundation
and two representatives from Chunghwa Post Co. Ltd. In accordance with the ROC Securities and Exchange Act, as amended, except with the approval of the Competent Authority (i.e. The Financial Supervisory Commission), a representative of the
government or of a juristic person, as a stockholder of our company, may not be concurrently selected or serve as the director or supervisor from the time of expiration of the term currently being served by our directors or supervisors.

The business address of our directors, supervisors and executive officers is the same as our registered address.

Our audit committee is responsible for: (i) selecting our independent registered public accounting firm and determining their
compensation; (ii) reviewing and discussing our annual, semi-annual and quarterly financial reports with our independent auditor; (iii) communicating with our independent auditors; (iv) approving our accounting firms annual
audit and non-audit service items; (v) negotiating the conflicts over our financial reports between our management and accounting firm; (vi) reviewing and assessing of our internal control policy; (vii) discussing and reporting other
financial information and required disclosure under the Securities Exchange Act of 1934 with our management and independent auditor; and (viii) performing one self-review each year. Our board of directors has concluded that Chung-Fern Wu is our
audit committee financial expert. As our audit committee will replace our supervisors after the beginning of the 7th session of our board of directors, according to Article 14-5 of the Securities and Exchange Act, the following items shall be
approved by a resolution of audit committee adopted by majority consent at a meeting with the majority of independent directors present: (i) the adoption or amendment of the internal control system, (ii) the assessment of the effectiveness
of the internal control system, (iii) the adoption or amendment of procedures governing material financial or operational actions, such as acquisition or disposal of assets and derivatives trading, (iv) a matter relating to the personal
interest of a director or supervisor, (v) a material asset or derivatives transaction, (vi) the offering, issuance, or private placement of any equity-related securities, (vii) a matter relating to significant loan, endorsement or
guarantee arrangement, (viii) the designation or dismissal of an attesting CPA, or the compensation given thereto, (ix) the appointment or discharge of a financial, accounting, or internal auditing officer, (x) the approval of annual
and semi-annual financial reports, and (xi) any other material matter so required by the Company or the competent authorities.

In addition to our audit committee, we also have a corporate strategy committee. Our corporate strategy committee may be composed of five to seven directors. Currently, there are six directors in the
Committee. It is responsible for reviewing and advising on the budgets, capital requirements, financial forecasts, matters related to investments, business license matters, corporate reorganization, development plans and other major issues affecting
our development. The conclusions of the corporate strategy committee are considered at a subsequent board of directors meeting. The board of directors passed a resolution on November 8, 2005 to set up a compensation committee, which is composed
of five directors. The Article 14-6 of ROC Securities and Exchange Act requires all listed companies to establish a compensation committee for directors, supervisors and managers compensation, which includes salary, stock options and other
rewards, as well as authorizes the Competent Authority (i.e. Financial Supervisory Commission) to enact a regulation on the authorities of the compensation committee and the qualifications of its members. Our board of directors passed a resolution
to amend the organization of our compensation committee on August 26, 2011. The compensation committee is composed of two independent directors (Chung-Yu Wang and Chung-Fern Wu) and one non-independent director (Jeng-Fang Jong) and is
responsible for drafting, approving and periodically reviewing the compensation proposals for the directors, supervisors, president, senior management, financial officer, accounting officer, and internal audit officer. See Item 10. Additional
InformationB. Memorandum and Articles of IncorporationDirectors.

In November 2003, the Securities and Exchange Commission approved changes to the New York
Stock Exchanges listing standards related to the corporate governance practices of listed companies. Under these rules, listed foreign private issuers, like us, must disclose any significant ways in which their corporate governance practices
differ from those followed by New York Stock Exchange-listed non-foreign private issuers under the New York Stock Exchanges listing standards. See Item 16G. Corporate Governance. A copy of the significant differences between our
corporate governance practices and New York Stock Exchange corporate governance rules applicable to non-foreign private issuers is also available on our website http://www.cht.com.tw. The information contained on our website is not a part of this

As of December 31, 2012, approximately 74% of our employees had university, graduate or
post-graduate degrees. To improve our operational efficiency by reducing personnel costs, we offered a number of voluntary retirement programs between June 1, 2000 and December 31, 2012, which resulted in a reduction of approximately
13,474 employees.

As of December 31, 2012, approximately 99% of our employees on a non-consolidated basis were members
of our principal labor union. Our collective agreement sets forth work rules, grievance procedures and provides for union participation in performance evaluations and promotion decisions. Our union members also occupy a majority of the seats on our
employee welfare and pension fund committees. We will continue to maintain a good relationship with our labor union. We strive to have good communication with our employees and the labor union by inviting representatives of our labor union to attend
various meetings related to the performance of our employees.

Pursuant to our articles of incorporation, our employees are entitled to 2% to 5% of the
distributable earnings as employee bonuses. Our practice in the past to determine the amount of the bonus has been based on the operating results. In the third quarter of 2012, we distributed an aggregate bonus to our employees of NT$2.0 billion
(US$0.1 billion). Since the change in accounting regulations requiring bonuses in the form of stocks be recorded as an expense at their market value instead of their par value, we instead decided to distribute cash bonuses.

E. Share Ownership

As
of March 31, 2013, our directors, supervisors and executive officers personally held an aggregate 722,845 shares of our common shares, representing around 0.01% of our outstanding common shares. The following table sets forth information with
respect to the beneficial ownership of our common shares as of March 31, 2013 by each of our directors, supervisors and executive officers.

##### Table of Contents

The Ministry of Transportation and Communications, on behalf of the government of the
Republic of China, owned approximately 35.29% of our outstanding common shares as of December 31, 2012. The remainder of our outstanding shares is held by public stockholders and other investors.

Directors, Supervisors and Audit Committee

Our articles of incorporation provide for a board of directors consisting of seven to fifteen members. Under Article 12 of our articles of incorporation amended in June 2012, we shall have three to five
supervisors until the end of the 6th session of board of directors, and shall establish a new audit committee starting from the 7thboard of directors in 2013 pursuant to Paragraph 1, Article 14-4 of the ROC Securities and Exchange Act. Therefore, we
will no longer have any supervisors after the beginning of our 7thsession of board of directors. See Item 6. Directors, Senior Management and EmployeesC. Board Practices for a discussion of our new audit committee starting from the date of the annual
general meeting in June 2013. For a company that has established an audit committee, the provisions regarding supervisors in ROC Securities and Exchange Act, the ROC Company Act, and other laws and regulations shall apply mutatis mutandis to the
audit committee.

Under the Republic of China Company Act, our board of directors, in conducting our business, shall act in
accordance with laws and regulations, our articles of incorporation and the resolutions adopted at the meetings of stockholders. Where any resolution adopted by our board of directors contravenes laws, our articles of incorporation and the
resolutions adopted at the meetings of stockholders, thereby causing loss or damage to us, all directors taking part in the adoption of such resolution shall be liable to compensate us for such loss or damage; however, those directors whose
disagreement appears on record or is expressed in writing shall be exempted from liability.

If our board
of directors decides, by resolution, to commit any act in violation of any law or our articles of incorporation, a supervisor (effective from the beginning of our 7thsession of board of directors, our audit committee) or any stockholder who has continuously held our shares for a
period of one year or longer may request our board of directors to discontinue such act. One or more stockholders who have held more than 3% of our issued and outstanding shares for over a year may require a supervisor to bring an action on our
behalf against a director for losses suffered by us as a result of the directors unlawful actions or failure to act by sending a written request to a supervisor (effective from the beginning of our 7thsession of board of directors, our audit committee). In addition, if
our stockholders meeting resolves to institute an action against a director, we shall, within 30 days from the date of such resolution, institute such an action. In the case of a lawsuit between us and a director, a supervisor (effective from
the beginning of our 7thsession of board of directors,
any of our independent directors) shall act on our behalf, unless otherwise provided by law; and our stockholders meeting may also appoint some other person to act on our behalf in a lawsuit.

In addition, our board of directors owes fiduciary duty to us. Our directors are liable to compensate us if they breach their fiduciary
duty.

According to the Republic of China Company Act, a director who has a personal interest in a matter to be discussed at
the meeting of the board of directors, shall specify such conflict; if the conflict may cause damages to the company, the director shall abstain from voting on the matter, and shall not serve as a proxy and vote on behalf of another director. Our
articles of incorporation also provide that we may make compensation to all directors and supervisors and such compensation shall not exceed 0.2% of our distributable earnings and may be approved only by a validly convened stockholders
meeting. Our articles of incorporation do not impose a mandatory retirement age for our directors. Furthermore, our articles of incorporation do not impose a shareholding qualification for each director. According to our current internal Loan
Procedures, we may not extend any loan to our directors or our supervisors.

Dividends and Distributions

At each annual general stockholders meeting, our board of directors submits to the stockholders for their approval any proposal for the distribution of dividend or the making of any other
distribution to stockholders from our net income for the preceding fiscal year. All common shares outstanding and fully paid as of the relevant record date are entitled to share equally in any dividend or other distribution so approved. Dividends
may be distributed in cash, in the form of common shares or a combination of the two, as determined by the stockholders at the meeting.

We are not permitted to distribute dividends or make other distributions to stockholders in any year in which we do not have any net income or retained earnings (excluding reserves). The Republic of China
Company Act also requires that 10% of our annual net income, less prior years losses and outstanding tax, if any, be set aside as a legal reserve until the accumulated legal reserve equals our paid-in capital. We may also set aside special
reserve as determined by our stockholders at a stockholders meeting. In addition, our articles of incorporation provide that at least 50% of the remaining portion of the net income, less prior years losses, outstanding taxes, the legal
reserve and any special reserve, plus undistributed retained earnings from prior years will be distributed as dividends to stockholders. Under our articles of incorporation, not less than 50% of the total amount of the distributed dividends must be
in cash, but if the cash dividends to be distributed are less than NT$0.10 per share, the dividends may be distributed in the form of shares. Pursuant to our current articles of incorporation, prior to distributing any dividends to our stockholders,
we were required to first distribute (i) between 2% and 5% of the distributable earnings to employees as bonuses and (ii) not more than 0.2% of the distributable earnings to directors and supervisors as compensation. Also, in accordance to
a clarification letter issued by the Ministry of Economic Affairs of Taiwan for the explanation of Article 64 of the Business Accounting Law on January 24, 2007, starting from January 1, 2008, employee bonuses are now categorized as an
expense instead of as distributable earnings.

Under the Republic of China Company Act as amended on January 4, 2012, if
we do not incur a loss, we are permitted to make distributions on a pro rata basis to our stockholders of additional common shares or cash by the legal reserve, the premium derived from the issuance of new shares and the income from endowments
received by us. Subject to the Republic of China Company Act, we are allowed to make the above distributions to our stockholders by legal reserve only if the legal reserve exceeds 25% of our paid-in capital. Furthermore, subject to the provision
under our articles of incorporation, such distribution should firstly be made by the premium derived from the issuance of new shares.

Changes in Share Capital

Under the Republic of China Company Act, any change in our authorized share capital requires an amendment to our articles of
incorporation, which in turn requires approval at our stockholders meeting. Authorized but unissued common shares may be issued, subject to applicable Republic of China law, upon terms as our board of directors may determine.

Preemptive Rights

Under
the Republic of China Company Act and our articles of incorporation, when we issue new shares for cash, existing stockholders who are listed on the stockholders register as of the record date have preemptive rights to subscribe for the new
issue in proportion to their existing shareholdings, unless the law or competent authority provides otherwise. Under our articles of incorporation, our employees, except for the directors and executives involved with the approval and passage of the
share issuance, have rights to subscribe for between 10% and 15% of any new issue.

In addition, in accordance with the
Republic of China Securities and Exchange Law, a public company that intends to offer new shares for cash must offer to the public at least 10% of the shares to be sold except in certain limited circumstances. This percentage can be increased by a
resolution passed at a stockholders meeting, held in accordance with the Company Act and our articles of incorporation which would diminish the number of new shares subject to the preemptive rights of existing stockholders.

Meetings of Stockholders

We are required by the Republic of China Company Act and our articles of incorporation to hold a general meeting of our stockholders within six months following the end of each fiscal year, unless for
specific legitimate reason or approved otherwise by the relevant authorities. Commencing from January 1, 2012, we must hold a general shareholders meeting within six months after the end of fiscal year and may not seek any extension for such
meeting accordingly to newly amended Article 36 of Securities and Exchange Act. These meetings are generally held in Taipei, Taiwan. Special stockholders meetings may be convened by resolution of the board of directors or by the board of
directors upon the written request of any stockholder or stockholders who have held 3% or more of the outstanding common shares for more than one year. Stockholders meetings may also be convened by a supervisor (effective from the beginning of
our 7th session of board of directors, our audit committee). Notice in writing of general meetings of stockholders, stating the place, time and agenda must be dispatched to each stockholder at least 30 days, in the case of general meetings, and 15
days, in the case of special meetings, before the date set for each meeting. Except in certain circumstances described below, a majority of the holders of all issued and outstanding common shares present at a stockholders meeting constitutes a
quorum for meetings of stockholders. Stockholders of 1% or more our issued and outstanding shares are entitled to submit one written proposal each year for consideration at our annual general stockholders meeting in accordance with the
Republic of China Company Act.

Voting Rights

As previously required by the Republic of China Company Act, our articles of incorporation provide that a holder of common shares has one vote for each common share. Cumulative voting applies to the
election of our directors and supervisors. Separate ballots may be held for the election of independent directors.

In
general, a resolution can be adopted by the holders of at least a majority of the common shares represented at a stockholders meeting at which the holders of a majority of all issued and outstanding common shares are present. Under the
Republic of China Company Act, the approval by at least a majority of the common shares represented at a stockholders meeting in which a quorum of at least two-thirds of all issued and outstanding common shares are represented is required for
major corporate actions, including:



| |  |  | amendment to our articles of incorporation;
| | - |  | -------------------------------------------



| |  |  | entering into, modification or termination of any contracts regarding leasing of all business, outsourcing of operations or joint operations;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | transfer of the whole or substantial part of our business or assets;
| | - |  | --------------------------------------------------------------------



| |  |  | taking over of the whole of the business or assets of any other company which would have significant impact on our operations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | distribution of any share dividend;
| | - |  | -----------------------------------



| |  |  | dissolution;
| | - |  | ------------



| |  |  | merger or spin-off; and
| | - |  | -----------------------



| |  |  | removing of directors or supervisors.
| | - |  | -------------------------------------

Alternatively, the Republic of China Company Act provides that in the case of a public company, such as us, a resolution may be adopted by the holders of at least two-thirds of the common shares
represented at a meeting of stockholders at which holders of at least a majority of issued and outstanding common shares are present.

##### Table of Contents

A stockholder may be represented at a general or special meeting by proxy if a valid proxy
form is delivered to us five days before the commencement of the general or special stockholders meeting. Except for trust enterprises or share registrar approved by the Securities and Futures Bureau of the Financial Supervisory Commission,
where one person is appointed as proxy by two or more stockholders who together hold more than 3% of the total issued common shares, the votes of those stockholders in excess of 3% of the outstanding common shares shall not be counted.
Alternatively, if the stockholder would like to exercise its voting right at a general or special meeting but cannot be present at the meeting in person, according to the regulations promulgated by the Financial Supervisory Commission on
February 20, 2012, starting from our 2012 general meeting, we are required to set up an electronic voting mechanism for such stockholder to exercise voting right. The stockholder is not allowed to exercise voting right through electronic voting
mechanism if such stockholder fails to revoke the granted proxy (if any) at least two days prior to the general or special meeting.

At the time of any vote, if a director of a public company has pledged more than half of the holding at the time the director was elected, such director will not be allowed to exercise the voting rights
with respect to the number of shares pledged, provided that the maximum number of shares ineligible for voting pursuant to the provision above cannot exceed half of the number of shares that such director held in such public company at the time the
director was elected. In addition, any shares that were ineligible for voting pursuant to the above provision would not count as being present for such vote.

Any stockholder who has a personal interest in the matter under discussion at a stockholders meeting, the outcome of which may impair our interests, shall not vote or exercise voting rights on
behalf of another stockholder; however, the shares held by such stockholder may be counted as present.

Holders of our ADSs
generally will not be able to exercise voting rights on the common shares underlying ADSs on an individual basis.

C. Other Rights of
Stockholders

Under the Republic of China Company Act, dissenting stockholders are entitled to appraisal rights in certain
major corporate actions, such as a planned transfer of the whole or part of the business or a proposed merger by us. A dissenting stockholder may request us to purchase back all of the shares owned by the stockholder at a fair price determined by
mutual agreement or determined by the court if a mutual agreement cannot be reached. Stockholders may exercise their appraisal rights by serving notice in writing to us prior to the related stockholders meeting and/or by raising his objection
at the stockholders meeting. Moreover, a stockholder has the right to file a petition in the court for annulment of any resolution adopted at a stockholders meeting where the procedures for convening the stockholders meeting or the
method of adopting the resolutions at the meeting is contrary to law or our articles of incorporation. One or more stockholders who have held more than 3% of the issued and outstanding shares of a company continuously for more than one year may
require a supervisor to institute, on behalf of us, an action against a director. In addition, one or more stockholders who has/have continuously held 3% or more of the total number of the outstanding shares of our company for more than one year may
require the board of directors to convene a special stockholders meeting by sending a written request to the board of directors.

The Republic of China Company Act allows stockholders holding 1% or more of the total issued shares of a company to submit, during the period of time prescribed by us no less than 10 days, one proposal in
writing for discussion at the general meeting of stockholders. It also provides that a company may adopt a nomination procedure for election of directors or supervisors. We have adopted a nomination procedure for election of directors as stipulated
in our articles of incorporation which provides that stockholders holding 1% or more of our total issued shares may submit to us a list of candidates for director, including independent director, along with relevant information and supporting
documents.

Register of Stockholders and Record Dates

Our share registrar, Yuanta Securities Co., Ltd., maintains our register of stockholders at its offices in Taipei, Taiwan. Under the Republic of China Company Act and our articles of incorporation, we
may, by giving advance public notice, set a record date and close the register of stockholders for a specified period in order for us to determine the stockholders or pledgees that are entitled to rights pertaining to the common shares. The
specified period required is as follows:



| |  |  | general stockholders meeting60 days;

The shares purchased by us shall not be pledged or hypothecated. In addition, we may not
exercise any stockholders rights attaching to these shares. Under ROC Company Act, we may transfer the treasury stock to our employees and impose transfer restrictions on the shares up to two years.

Liquidation Rights

In
the event of our liquidation, the assets remaining after payment of all debts, liquidation expenses and taxes will be distributed pro rata to the stockholders in accordance with the relevant provisions of the Republic of China Company Act and our
articles of incorporation.

Substantial Stockholders and Transfer Restrictions

The Republic of China Securities and Exchange Act currently requires for public companies that (i) each director, supervisor,
manager, as well as their respective spouses, minor children and nominees, and substantial stockholder (i.e., a stockholder who together with his or her spouse, minor children or nominees, holds more than 10% of the shares of a public company) to
report any change in that persons shareholding to the issuer of the shares on a monthly basis and (ii) each director, supervisor, manager or substantial stockholder holding such common shares for more than a six month period to report his
or her intent to transfer any shares listed on the TWSE or traded on the GreTai Securities Market to the Securities and Futures Bureau of the Financial Supervisory Commission at least three days before the intended transfer, unless the number of
shares to be transferred is less than 10,000 shares. ADS holders holding more than 10% of our common shares, including common shares represented by ADSs, may be subject to the reporting obligation in above item (i).

In addition, the number of shares that can be sold or transferred on the TWSE or GreTai Securities Market by any person subject to the
restrictions described above on any given day may not exceed:



| |  |  | 0.2% of the outstanding shares of the company in the case of a company with no more than 30 million outstanding shares;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | 0.2% of 30 million shares plus 0.1% of the outstanding shares exceeding 30 million shares in the case of a company with more than
30 million outstanding shares; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in any case, 5% of the average daily trading volume (number of shares) on the TWSE or the GreTai Securities Market for the ten consecutive trading days
preceding the reporting day on which day the director, supervisor, manager or substantial stockholder or their respective spouse, minor child or nominee reports the intended share transfer to the Securities and Futures Bureau.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These restrictions do not apply to block trading, auction sale, purchase by auction, after-hour trading and
sales or transfers of our ADSs. However, these restrictions will apply to sales of common shares upon withdrawal.

General

Historically, foreign investments in the securities market of Taiwan were restricted. However, commencing in 1983, the Taiwan government has from time to time enacted legislation and adopted regulations
to make foreign investment in the Taiwan securities market possible. Initially, only overseas investment trust funds of authorized securities investment trust enterprises established in Taiwan were permitted to invest in the Taiwan securities
market. Since January 1, 1991, qualified foreign institutional investors are allowed to make investments in the Taiwan listed securities market. Since March 1, 1996, overseas Chinese, non-resident foreign institutional and individual
investors (other than qualified foreign institutional investors), called general foreign investors, are permitted to make direct investments in the Taiwan securities market.

Foreign Investment in Taiwan Securities Market

On December 28, 1990,
the Executive Yuan, the cabinet of the government of the Republic of China, approved guidelines drafted by the Securities and Futures Commission (the predecessor of the Securities and Futures Bureau), which, since January 1, 1991, has allowed
direct foreign investment in Taiwans securities that are listed on the TWSE or other Taiwan securities approved by the Securities and Futures Bureau by certain eligible qualified foreign institutional investors.

In addition to qualified foreign institutional investors, certain individual and foreign institutional investors which meet certain
qualifications set by the Securities and Futures Bureau may invest in the shares of TWSE-listed companies, GreTai Securities Market (formerly known as Over-The-Counter Securities Exchange) traded companies, emerging market companies or other Taiwan
securities approved by the Securities and Futures Bureau up to a limit of US$50 million (in the case of institutional investors) and US$5 million (in the case of individual investors) after obtaining permission from the TWSE.

On September 30, 2003 and June 15, 2004, the Securities and Futures Bureau issued amendments to the Guideline Governing
Investment in Securities by Overseas Chinese and Foreign Nationals and relevant regulations, in which the Securities and Futures Bureau lifted certain restrictions and simplified the procedures required for foreign investments in Taiwans
securities market. The amendment focuses mainly on the following aspects:



| |  |  | The concept of qualified foreign institutional investors no longer exists. Foreign investors are reclassified as off-shore foreign
institutional investors, on-shore foreign institutional investors, off-shore general foreign investors or on-shore general foreign investors based on whether they are institutions or natural persons, and
whether they have presence in Taiwan.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For foreign investors to invest in Taiwans securities market, registration with the TWSE, instead of the approval of the Securities and Futures
Bureau, is required. The TWSE may withdraw or rescind the registration if the application documents submitted by foreign investors are untrue or incomplete, or if any material violation of the relevant regulations exists.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Off-shore foreign investors may provide the securities they hold as the underlying shares of depositary receipts and act as selling stockholders in
depositary receipts offerings.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Off-shore foreign institutional investors are required to appoint their agent or nominee to attend the stockholders meeting of the invested
company.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------

Currently, subject to the specific restriction imposed by relevant regulations, the off-shore
foreign institutional investors may invest in the Taiwan securities market without any amount restriction. However, a ceiling will be separately determined by the Securities and Futures Bureau after consultation with the Central Bank of the Republic
of China (Taiwan) for investment by offshore oversea Chinese and foreign individual investors.

Foreign Investment Approval

Other than:



| |  |  | foreign institutional investors;
| | - |  | --------------------------------



| |  |  | foreign individual investors; and
| | - |  | ---------------------------------



| |  |  | investors in overseas convertible bonds and depositary receipts,
| | - |  | ----------------------------------------------------------------

foreign investors who wish to make direct investments in the shares of Taiwan companies may submit a foreign investment approval application to the Investment Commission of the Ministry of
Economic Affairs of Taiwan or other government authority to qualify for benefits granted under the Statute for Investment by Foreign Nationals. The Investment Commission or other government authority reviews each foreign investment approval
application and approves or disapproves the application after consultation with other governmental agencies. Any non-Taiwan person possessing a foreign investment approval may remit capital for the approved investment and repatriate annual net
profits and interests and cash dividends attributable to an approved investment. Stock dividends, investment capital and capital gains attributable to the investment may be repatriated with approval of the Investment Commission or other government
authority.

In addition to the general restrictions against direct investment by non-Taiwan persons in Taiwan companies,
non-Taiwan persons are currently prohibited from investing in prohibited industries in Taiwan under the Negative List promulgated by the Executive Yuan from time to time. The prohibition on direct foreign investment in the prohibited industries in
the Negative List is absolute with the consequence of certain specific exemption from the application of the Negative List. Under the Negative List, some other industries are restricted so that non-Taiwan persons may directly invest only up to a
specified level and with the specific approval of the relevant authority which is responsible for enforcing the legislation which the negative list is intended to implement. The telecommunication industry is a restricted industry under the Negative
List.

Depositary Receipts

In April 1992, the Securities and Futures Bureau began allowing Taiwan companies listed on the TWSE, with the prior approval of the Securities and Futures Bureau, to sponsor the issuance and sale of
depositary receipts evidencing depositary shares. In December 1994, the Republic of China Ministry of Finance began allowing companies whose shares are traded on the GreTai Securities Market also to sponsor the issuance and sale of depositary
receipts evidencing depositary shares representing shares of its capital stock. Approvals for these issuances are still required.

After the issuance of a depositary share, a holder of the depositary receipt evidencing the depositary shares may request the depositary issuing the depositary share to cause the underlying shares to be
sold in Taiwan and to distribute the proceeds of the sale, or to withdraw the shares and deliver the shares to the depositary receipt holder. A citizen of the Peoples Republic of China is not permitted to withdraw and hold our shares.

If you are an offshore foreign institutional investor holding the depositary receipts, you must register with the TWSE as a
foreign investor before you will be permitted to withdraw the shares represented by the depositary receipts. In addition to obtaining registration with the TWSE, you must also (i) appoint a qualified local agent to, among other things, open a
securities trading account with a local securities brokerage firm and a bank account to remit funds, exercise stockholders rights and perform other functions as holders of ADSs may designate, (ii) appoint a custodian bank to hold the
securities and cash proceeds, confirm transactions, settle trades and report and declare other relevant information; and (iii) appoint a tax guarantor as guarantor for the full compliance of the withdrawing depositary receipt holders tax
filing and payment obligations in the Republic of China. A depositary receipt holder not registered as a foreign investor with the TWSE, or a holder that has made the necessary appointments as outlined above, will be unable to hold, or subsequently
transfer, the shares withdrawn from the depositary receipt facility.

##### Table of Contents

No deposits of shares may be made in a depositary receipt facility and no depositary shares
may be issued against deposits without specific Securities and Futures Bureau approval, unless they are:



| | (i) | stock dividends;
| | --- | ----------------



| | (ii) | free distributions of shares;
| | ---- | -----------------------------



| | (iii) | due to the exercise by the depositary receipt holders preemptive rights in the event of capital increases for cash; or
| | ----- | -----------------------------------------------------------------------------------------------------------------------



| | (iv) | if permitted under the deposit agreement and custody agreement and within the amount of depositary receipts which have been withdrawn, due to the direct purchase by
investors or purchase through the depositary on the TWSE or the GreTai Securities Market or delivery by investors of the shares for deposit in the depositary receipt facility. In this event, the total number of depositary receipts outstanding after
an issuance cannot exceed the number of issued depositary receipts previously approved by the Securities and Futures Bureau of the Financial Supervisory Commission in connection with the offering, plus any ADSs issued pursuant to the events
described in (i), (ii) and (iii) above.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

An ADS holder or the depositary, without obtaining further
approvals from the Central Bank of the Republic of China (Taiwan) or any other governmental authority or agency of the Republic of China, may convert NT dollars into other currencies, including U.S. dollars, in respect of:



| |  |  | the proceeds of the sale of common shares represented by ADSs or received as share dividends with respect to the common shares and deposited into the
depositary receipt facility; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any cash dividends or distributions received from the common shares.
| | - |  | --------------------------------------------------------------------

In addition, the depositary may also convert into NT dollars incoming payments for purchases of common shares for deposit in the
depositary receipt facility against the creation of additional ADSs. If you withdraw the common shares underlying your ADSs and become a holder of our common shares, you may convert into NT dollars subscription payment for rights offerings. The
depositary may be required to obtain foreign exchange payment approval from the Central Bank of the Republic of China (Taiwan) on a payment-by-payment basis for conversion from NT dollars into foreign currencies of the proceeds from the sale of
subscription rights of new common shares. Although it is expected that the Central Bank of the Republic of China (Taiwan) will grant approval as a routine matter, required approvals may not be obtained in a timely manner, or at all.

Exchange Controls

Taiwans Foreign Exchange Control Statute and regulations provide that all foreign exchange transactions must be executed by banks
designated by the Financial Supervisory Commission and by the Central Bank of the Republic of China (Taiwan) to handle foreign exchange transactions. Current regulations favor trade-related foreign exchange transactions. Consequently, foreign
currency earned from exports of merchandise and services may now be retained and used freely by exporters. All foreign currency needed for the importation of merchandise and services may be purchased freely from the designated foreign exchange
banks.

Aside from trade-related foreign exchange transactions, Taiwan companies and residents may remit to and from Taiwan
foreign currencies of up to US$50 million (or its equivalent) and US$5 million (or its equivalent), respectively, in each calendar year. These limits apply to remittances involving a conversion between New Taiwan dollars and U.S. dollars or other
foreign currencies. A requirement is also imposed on all private enterprises to register all medium and long-term foreign debt with the Central Bank of the Republic of China (Taiwan).

In addition, a foreign person without an alien resident card or an unrecognized foreign entity may remit to and from Taiwan foreign
currencies of up to US$100,000 per remittance if required documentation is provided to Taiwan authorities. This limit applies only to remittances involving a conversion between New Taiwan dollars and U.S. dollars or other foreign currencies.

F. Taxation

Republic of China Taxation

The discussion below describes the principal
Republic of China tax consequences of the ownership and disposition of ADSs representing common shares and of common shares. It applies to you only if you are:



| |  |  | an individual who is not a citizen of the Republic of China, who owns ADSs or common shares and who is not physically present in Taiwan for 183 days or
more during any calendar year (the Non-Resident Individual); or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a corporation or a non-corporate body that is organized under the laws of a jurisdiction other than the Republic of China for profit-making purposes
and has no fixed place of business or other permanent establishment in Taiwan (the Non-Resident Entity).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

You should also consult your tax advisors concerning the tax consequences of owning ADSs and common shares in the Republic of China and any other relevant taxing jurisdiction to which they are subject.

Dividends

Dividends declared by us out of our retained earnings and distributed to you are subject to Republic of China withholding tax, currently at the rate of 20%, on the amount of the distribution in the case
of cash dividends or on the par value of the common shares in the case of stock dividends. However, a 10% Republic of China retained earnings tax paid by us on our undistributed after-tax earnings, if any, may provide a credit of up to 10% of the
gross amount of any dividends declared out of such earnings that would reduce the 20% Republic of China withholding tax imposed on these distributions.

Share or cash dividends paid by us out of our capital surplus which are derived from the issuance of shares at a premium are not subject to Republic of China withholding tax. According to the rulings of
Ref. Tai-Tsai-Hsuei-Tzi-09504509440 issued by the Ministry of Finance of the Republic of China, if a company reduces its share capital and redeems for cash its outstanding common shares issued to the companys stockholders by capitalization of
capital surplus, those premiums under the capitalized capital surplus derived from re-evaluation of assets, sale of lands and/or merger with other enterprise shall be deemed as the gain in the stockholders capital investment, and shall be
deemed as stockholders dividend income (or investment revenue) and be subject to ROC income tax.

As the legal reserve
is set-aside from companys profit earnings (after tax) in accordance with Article 237 of ROC Company Act, receipt of distribution of legal reserve shall be deemed as stockholders dividend income (or investment revenue) and be subject to
ROC income tax collected by way of withholding at the time of distribution, currently at the rate of 20%, unless a lower withholding rate is provided under a tax treaty between the ROC and the jurisdiction where the Non-ROC Stockholder is a
resident.

Capital Gains

Gains from the sale of property in the Republic of China are generally subject to Republic of China income tax. Effective January 1, 2013, capital gains on the sale of common shares, including common
shares withdrawn from the ADS facility, received by a Non-Resident Individual is subject to the capital gain tax at a flat rate of 15%. A Non-Resident Entity is exempted from income tax for its capital gains from sale of common shares, including
common shares withdrawn from the ADS facility, and is further exempted from Alternative Minimum Tax, or the AMT.

Sales of
ADSs by you are regarded as transactions relating to property located outside the Republic of China and thus any gains derived therefrom are currently not subject to Republic of China income tax.

##### Table of Contents

Preemptive Rights

Distributions of statutory preemptive rights for common shares in compliance with Republic of China law are not subject to any Republic of China tax. Proceeds derived from sales of statutory preemptive
rights evidenced by securities are subject to securities transaction tax at the rate of 0.3% of the gross amount received. A Non-Resident Individual is subject to income tax at a flat rate of 15% for such capital gains. A Non-Resident Entity is
exempted from income tax for such capital gains and is further exempted from the AMT. Proceeds derived from sales of statutory preemptive rights which are not evidenced by securities are subject to capital gains tax at the rate of:



| |  |  | 20% of the gains realized if you are a natural person; or
| | - |  | ---------------------------------------------------------



| |  |  | 20% of the gains realized if you are an entity that is not a natural person.
| | - |  | ----------------------------------------------------------------------------

Subject to compliance with Republic of China law, we, at our sole discretion, can determine whether statutory preemptive rights shall be
evidenced by issuance of securities.

Securities Transaction Tax

A securities transaction tax, at the rate of 0.3% of the gross amount received, payable by the seller will be withheld upon a sale of
common shares in Taiwan. Transfers of ADSs are not subject to Republic of China securities transaction tax. According to a letter issued by the Ministry of Finance of the Republic of China in 1996, withdrawal of common shares from the deposit
facility will not be subject to Republic of China securities transaction tax.

Estate Taxation and Gift Tax

Republic of China estate tax is payable on any property within Taiwan of a deceased person who is a non-resident individual, and Republic
of China gift tax is payable on any property within Taiwan donated by any such person. Under Republic of China estate and gift tax laws, common shares issued by Taiwan companies are deemed located in Taiwan regardless of the location of the owner.
It is not clear whether the ADSs will be regarded as property located in Taiwan under Republic of China estate and gift tax laws. Starting from January 21, 2009, the estate tax and gift tax rates were reduced to 10%.

Tax Treaty

The
Republic of China does not have an income tax treaty with the United States. On the other hand, the Republic of China has income tax treaties with Indonesia, Israel, Singapore, South Africa, Australia, Vietnam, New Zealand, Malaysia, Macedonia,
Swaziland, the Netherlands, United Kingdom, Gambia, Senegal, Sweden, Belgium, Denmark, Paraguay, Hungary, France, India, Slovakia, Germany, Thailand and Switzerland, which may limit the rate of Republic of China withholding tax on dividends paid
with respect to common shares in Taiwan companies. It is unclear whether if you hold ADSs, you will be considered to hold common shares for the purposes of these treaties. Accordingly, if you may otherwise be entitled to the benefits of the relevant
income tax treaty, you should consult your tax advisors concerning your eligibility for the benefits with respect to the ADSs.

Retained
Earnings Tax

Under the Republic of China Income Tax Laws, a 10% retained earnings tax will be imposed on a company for
its after-tax earnings generated after January 1, 1998 which are not distributed in the following year. The retained earnings tax so paid will further reduce the retained earnings available for future distribution. When the company declares
dividends out of those retained earnings, up to a maximum amount of 10% of the declared dividends may be credited against the 20% withholding tax imposed on the non-resident holders of its shares.

U.S. Federal Income Tax Considerations for U.S. Holders

The following is a summary of certain U.S. federal income tax consequences of the ownership and disposition of our shares and ADSs as of
the date hereof. The discussion set forth below is applicable to beneficial owners of our shares or ADSs that hold the shares or ADSs as capital assets and that are U.S. holders and non-residents of the Republic of China. You are a U.S. holder if
you are:



| |  |  | an individual who is a citizen or resident of the United States;
| | - |  | ----------------------------------------------------------------



| |  |  | a corporation or other entity taxable as a corporation for U.S. federal income tax purposes created or organized in or under the laws of the United
States, any state thereof or the District of Columbia;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an estate the income of which is subject to U.S. federal income taxation regardless of its source;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | a trust that is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all
substantial decisions of the trust; or
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a trust that has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

This summary is based on the provisions of the Internal Revenue Code of 1986, as amended (the Code), and regulations, rulings
and judicial decisions thereunder as of the date hereof, and such authorities may be replaced, revoked or modified so as to result in U.S. federal income tax consequences different from those discussed below. It is for general purposes only and you
should not consider it to be tax advice. In addition, it is also based in part on representations made by the depositary and assumes that the deposit agreement and any related agreement will be performed in accordance with their terms. This summary
does not represent a detailed description of all the U.S. federal income tax consequences to you in light of your particular circumstances and does not address the effects of any state, local or non-U.S. tax laws (or other U.S. federal tax
consequences, such as U.S. federal estate or gift tax consequences). In addition, it does not represent a detailed description of the U.S. federal income tax consequences applicable to you if you are subject to special treatment under the U.S.
federal income tax laws, including if you are:



| |  |  | a dealer in securities or currencies;
| | - |  | -------------------------------------



| |  |  | a trader in securities if you elect to use a mark-to-market method of accounting for your securities holdings;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | a financial institution or an insurance company;

##### Table of Contents

We cannot assure you that a later change in law will not alter significantly the tax
considerations that we describe in this summary.

If a partnership holds our shares or ADSs, the tax treatment of a partner
will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our shares or ADSs, you should consult your tax advisor.

You should consult your own tax advisor concerning the particular U.S. federal income tax consequences to you of the ownership and
disposition of the shares or ADSs, as well as the consequences to you arising under the laws of any other taxing jurisdiction.

In general, for U.S. federal income tax purposes, a U.S. holder who is the beneficial owner of an ADS will be treated as the owner of the shares underlying such ADS. Deposits or withdrawals of shares,
actually or constructively, by U.S. holders for ADSs will not be subject to U.S. federal income tax.

The U.S. Treasury has
expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS may be taking actions that are inconsistent with the claiming of foreign tax credits by U.S. holders of
ADSs. Such actions would also be inconsistent with the claiming of the reduced rate of tax, described in Taxation of Dividends below, applicable to dividends received by certain non-corporate holders. Accordingly, the analysis of
the credibility of Republic of China taxes and the availability of the reduced tax rate for dividends received by certain non-corporate holders, each described in Taxation of Dividends below, could be affected by actions taken by
intermediaries in the chain of ownership between the holder of the ADS and the issuer of the security underlying the ADS.

Taxation of
Dividends

The gross amount of distributions (other than certain pro rata distributions of shares to all stockholders)
you receive on your shares or ADSs, including net amounts withheld in respect of Republic of China withholding taxes, will generally be treated as dividend income to you to the extent the distributions are made from our current and accumulated
earnings and profits as calculated according to U.S. federal income tax principles. These amounts (including withheld taxes) will be includible in your gross income as ordinary income on the day you actually or constructively receive the
distributions, which in the case of an ADS will be the date received by the depositary. You will not be entitled to claim a dividends-received deduction allowed to corporations under the Code with respect to distributions you receive from us.

With respect to U.S. holders who are individuals, certain dividends received from a foreign corporation, on shares, or ADSs
backed by such shares, that are readily tradable on an established securities market in the United States may be subject to reduced rates of taxation, provided further that the foreign corporation was not, in the year prior to the year in which the
dividends are paid, and is not, in the year in which the dividends are paid, a passive foreign investment company (see Passive Foreign Investment Company below). Under current U.S. Treasury Department guidance, our ADSs, which are listed
on the New York Stock Exchange, but not our shares, are treated as readily tradable on an established securities market in the United States. Thus, we do not believe that dividends that we pay on our shares that are not backed by ADSs currently meet
the conditions required for these reduced tax rates. There can be no assurance that our ADSs will continue to be readily tradable on an established securities market in later years, or that our shares will be readily tradable on an established
securities market in any given year. Individuals that do not meet a minimum holding period requirement during which they are not protected from the risk of loss, or that elect to treat the dividend income as investment income pursuant to
Section 163(d)(4) of the Code, will not be eligible for the reduced rates of taxation regardless of the trading status of our shares or ADSs. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is
obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. You should consult your own tax advisor regarding the application
of these rules given your particular circumstances.

The amount of any dividend paid in NT dollars will equal the U.S. dollar
value of the NT dollars you receive, calculated by reference to the exchange rate in effect on the date you actually or constructively receive the dividend, which in the case of an ADS will be the date received by the depositary, regardless of
whether the NT dollars are actually converted into U.S. dollars. If the NT dollars received as a dividend are not converted into U.S. dollars on the date of receipt, you will have a basis in the NT dollars equal to their U.S. dollar value on the
date of receipt. Any gain or loss you realize if you subsequently sell or otherwise dispose of the NT dollars will be ordinary income or loss from sources within the United States for foreign tax credit limitation purposes.

##### Table of Contents

Subject to certain conditions and limitations under the Code, you may be entitled to a
credit or deduction against your U.S. federal income taxes for the net amount of any Republic of China taxes that are withheld from dividend distributions made to you. In determining the amounts withheld in respect of Republic of China taxes, any
reduction of the amount withheld on account of a Republic of China credit in respect of the 10% retained earnings tax imposed on us is not considered a withholding tax and will not be treated as distributed to you or creditable by you against your
U.S. federal income tax. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For purposes of calculating the foreign tax credit, dividends we pay with respect to shares or ADSs
will generally be considered passive category income from sources outside the United States. Further, a U.S. holder that



| |  |  | has held shares or ADSs for less than a specified minimum period during which it is not protected from risk of loss, or
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | is obligated to make payments related to the dividends,
| | - |  | -------------------------------------------------------

may not be allowed a foreign tax credit for foreign taxes imposed on dividends paid on shares or ADSs. The rules governing the foreign tax credit are complex. We therefore urge you to consult your tax
advisor regarding the availability of the foreign tax credit under your particular circumstances.

To the extent that the
amount of any distribution you receive exceeds our current and accumulated earnings and profits for a taxable year, as determined under U.S. federal income tax principles, the distribution will first be treated as a tax-free return of capital,
causing a reduction in your adjusted basis in the shares or ADSs and thereby increasing the amount of gain, or decreasing the amount of loss, you will recognize on a subsequent disposition of the shares or ADSs. The balance in excess of adjusted
basis, if any, will be taxable to you as capital gain recognized on a sale or exchange. However, we do not expect to keep earnings and profits in accordance with U.S. federal income tax principles. Therefore, you should expect that a distribution
will generally be treated as a dividend.

It is possible that pro rata distributions of shares or ADSs to all stockholders may
be made in a manner that is not subject to U.S. federal income tax. The basis of any new shares or ADSs so received will generally be determined by allocating your basis in the old shares or ADSs between the old shares or ADSs and the new shares or
ADSs, based on their relative fair market values on the date of distribution.

For U.S. tax purposes, any such tax-free share
distribution would not result in foreign source income to you. Consequently, you may not be able to use the foreign tax credit associated with any Republic of China withholding tax imposed on such distributions unless you can use the credit (subject
to applicable limitations) against U.S. federal income tax due on other foreign source income in the appropriate category for foreign tax credit purposes.

Taxation of Capital Gains

When you sell or otherwise dispose of
your shares or ADSs, you will generally recognize capital gain or loss in an amount equal to the difference between the U.S. dollar value of the amount realized for the shares or ADSs and your basis in the shares or ADSs, determined in U.S. dollars.
For foreign tax credit limitation purposes, such gain or loss will generally be treated as U.S. source gain or loss. If you are an individual and have held the shares or ADSs being sold or otherwise disposed for more than one year, your gain
recognized will be eligible for reduced rates of taxation. Your ability to deduct capital losses is subject to limitations.

Any Republic of China securities transaction taxes that you pay generally will not be creditable foreign taxes for U.S. federal income
tax purposes, but you may be able to deduct such taxes, subject to certain limitations under the Code. You are urged to consult your tax advisors regarding the U.S. federal income tax consequences of these taxes.

Passive Foreign Investment Company

We believe that we were not a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for our
taxable year ending on December 31, 2012, and we do not expect to become one for our current taxable year or in the future, although there can be no assurance in this regard. If we were treated as a PFIC for any taxable year during which you
held our shares or ADSs, you could be subject to additional U.S. federal income taxes on gain recognized with respect to the shares or ADSs and on certain distributions, plus an interest charge on certain taxes treated as having been deferred under
the PFIC rules.

Non-corporate U.S. holders will not be eligible for reduced rates of taxation on any dividends received from
us, if we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year.

Information Reporting and
Backup Withholding

In general, information reporting will apply to dividends in respect of our shares or ADSs and the
proceeds from the sale, exchange or redemption of our shares or ADSs that are paid to you within the United States (and in certain cases, outside the United States), unless you are an exempt recipient such as a corporation. A backup withholding tax
may apply to such payments if you fail to provide a taxpayer identification number or certification of other exempt status or fail to report in full dividend and interest income.

Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your U.S. federal income tax
liability provided the required information is furnished to the Internal Revenue Service.

Information Return under Section 6045B
of the Internal Revenue Code

Section 6045B of the Code imposes certain reporting requirements on us with respect
to any organizational action that affects the basis of our shares or ADSs, such as the capital reduction plan described in Item 9 under A. Offer and Listing Details. We intend to comply with the requirements by making available on
our website IRS Form 8937, Report of Organizational Actions Affecting Basis of Securities, with respect to such capital reduction plan and any other such organizational action.

|ITEM 11. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Market risk is the risk of loss related to adverse changes in market prices, including interest rates and foreign exchange rates, of financial instruments. In the normal course of business, we are
routinely subject to a variety of risks, including market risk associated with interest rate movements, currency rate movements on non-NT dollar denominated assets and liabilities and equity price movements on our portfolio of equity securities.

We regularly assess these financial instruments and their ability to address market risk and have established policies and
business practices to protect against the adverse effects of these and other potential exposures.

Interest Rate Risk

We do not expect interest rate risk to have a material impact on our financial condition and results of operations. Please refer to
Item 5. Operating and Financial Review and ProspectsB. Liquidity and Capital Resources for a discussion of our loans.

For our non-fixed interest rate loans, the interest rates will change in accordance with the fixed rates of the banks we borrowed from. Assuming an increase or decrease of 1% in the interest rates of our
non-fixed interest rate loans, our interest payments in 2012 would have increased or decreased by NT$21 million (US$0.7 million). We have not used any derivative financial instruments to hedge interest rate risk. We have not been exposed nor do we
anticipate being exposed to material risks due to changes in interest rates. As of December 31, 2012, our cash and cash equivalents amounted to NT$53.2 billion (US$1.8 billion). The risk associated with fluctuating interest rates is principally
confined to our cash deposits in banks, which is one of the many ways we manage our capital, and interest income accounts for only a very small percentage of our total revenue. Therefore, we believe our exposure to interest rate risk is immaterial.

Foreign Currency Risk

We are exposed to foreign currency risk as a result of (i) our foreign currency and derivative trading activities; (ii) our telecommunications equipment being sourced from overseas suppliers;
(iii) our international settlement payments associated with our services for international calls and roaming traffic; and (iv) securities denominated in foreign currencies.

We entered into currency swap and forward exchange contracts to reduce our exposure to foreign currency risk due to fluctuations in
exchange rates. Outstanding currency swap and forward exchange contracts on December 31, 2012 were as follows:



|                               |  |                     |  |                 |  |                             
|------------------------------ |  | ------------------- |  | --------------- |  | ----------------------------

|Forward exchange contracts-Buy |  | NT$/US$             |  | 2013.01         |  | NT$154 million/US$5 million 

Net loss arising from all of our foreign currency derivative financial instruments for the year ended
December 31, 2011 was NT$72.8 million, including realized settlement loss of NT$40.9 million and valuation loss of NT$31.9 million.

##### Table of Contents

Net gain arising from all of our foreign currency derivative financial instruments for the
year ended December 31, 2012 was NT$68.6 million (US$2.4 million), including realized settlement gain of NT$70.0 million (US$2.5 million), which was partially offset by valuation loss of NT$1.4 million (US$0.1 million).

Equity Price Risk

We
are exposed to equity price risk as a result of our available-for-sale equity securities, including publicly-traded equities and foreign currency-denominated mutual funds, and we manage our equity investment portfolio in accordance with our internal
regulations.

The table below presents the carrying amount and unrealized gain or loss for our available-for-sale equity
securities as of December 31, 2012.

The total value of our available-for-sale equity portfolio amounted to NT$5.4 billion (US$185.7 million)
as of December 31, 2012, which was approximately 118% more than the total value of our equity portfolio as of December 31, 2011. This increase was mainly due to the acquisition of NT$3.1 billion stake in China Airlines, as well as benefit
from market rally over 2012. Compared to a net unrealized gain of NT$69.0 million on our equity portfolio at the end of 2011, we recognized a net unrealized gain of NT$262 million (US$9.0 million) on our equity portfolio as of December 31,
2012. The increase in unrealized gain was mainly due to rising prices in both global equity markets and fixed income markets.

For the year ended December 31, 2012, pursuant to ROC and U.S. accounting regulations, we recognized other-than-temporary impairment
losses of NT$27 million (US$0.9 million) for available-for-sale financial assets due to the decline in market prices of which we cannot estimate the time of recovery. The value of our equity holdings fluctuates depending on the market conditions.
However, we do not expect the gains and losses in the values of the equities that we hold to have a material impact on our financial condition and results of operations.

Other Market Risk

We have made investments in corporate bonds and bank
debentures issued by domestic public companies with strong industry leadership and solid profits. Industries in which we have invested include materials, financials, utilities, technology, and so on. As of December 31, 2012, total value of our
investments in corporate bonds and bank debentures amounted to NT$16.1 billion (US$554.1 million), most of which were classified as held-to-maturity financial assets, except for a NT$50.2 million (US$1.7 million) corporate bonds classified as
available-for-sale financial asset on recognition. The fair value of these corporate bonds and bank debentures is valued using market-based observable inputs including duration, yield rate and credit rating, which are subject to fluctuation based on
many factors such as prevailing market conditions. However, we do not expect the gains and losses in the values of these investments to have a material impact on our financial condition and results of operations.

Under the terms of the deposit agreement for our ADSs, an ADS holder may have to pay the following service fees to the depositary:



|                                                                                                  |  |

|Cancellation of ADSs                                                                              |  | Up to US$5.00 per 100 ADS cancelled
|Distribution of cash dividends or other cash distributions                                        |  | Up to US$2.00 per 100 ADS held     
|Distribution of ADSs pursuant to stock dividends, free stock distributions or exercises of rights |  | Up to US$5.00 per 100 ADS held     
|Distribution of securities other than ADSs or rights to purchase additional ADSs                  |  | Up to US$5.00 per 100 ADS held     

Depositary Charges

In addition, an ADS holder shall be responsible for the following charges:



| |  |  | taxes (including applicable interest and penalties) and other governmental charges;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | such registration fees as may from time to time be in effect for the registration of common shares or other deposited securities on the share register
and applicable to transfers of common shares or other deposited securities to or from the name of the custodian, the depositary or any nominees upon the making of deposits and withdrawals, respectively;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | such cable, telex and facsimile transmission and delivery expenses as are expressly provided in the deposit agreement to be at the expense of ADS
holders and beneficial owners of ADSs;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the expenses and charges incurred by the depositary in the conversion of foreign currency; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | the fees and expenses incurred by the depositary, the custodian or any nominee in connection with the servicing or delivery of deposited securities.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------

Depositary fees payable upon the issuance and cancellation of ADSs are typically paid to the depositary by
the brokers (on behalf of their clients) receiving the newly-issued ADSs from the depositary and by the brokers (on behalf of their clients) delivering the ADSs to the depositary for cancellation. The brokers in turn charge these transaction fees to
their clients.

Depositary fees payable in connection with distributions of cash or securities to ADS holders and the
depositary services fee are charged by the depositary to the holders of record of ADSs as of the applicable ADS record date. The depositary fees payable for cash distributions are generally deducted from the cash being distributed. In the case of
distributions other than cash (i.e., stock dividends, rights offerings), the depositary charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case of ADSs registered in the name of the investor (whether
certificated or un-certificated in direct registration), the depositary sends invoices to the applicable record date ADS holders. In the case of ADSs held in brokerage and custodian accounts via the central clearing and settlement system, The
Depository Trust Company, or DTC, the depositary generally collects its fees through the systems provided by DTC (whose nominee is the registered holder of the ADSs held in DTC) from the brokers and custodians holding ADSs in their DTC accounts. The
brokers and custodians who hold their clients ADSs in DTC accounts in turn charge their clients accounts the amount of the fees paid to the depositary.

##### Table of Contents

In the event of refusal to pay the depositary fees, the depositary may, under the terms of
the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder.

The fees and charges ADS holders may be required to pay may vary over time and may be changed by us and by the depositary. ADS holders
will receive prior notice of such changes.

Payments by Depositary

institute a sponsored ADR program are treated as U.S.-source royalty income. Such income is therefore subject to a U.S. withholding tax of 30% or a lower applicable income tax treaty rate.

Managements Annual Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined
in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended, for our company. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of consolidated financial statements in accordance with generally accepted accounting principles and includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and
fairly reflect the transactions and dispositions of a companys assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally
accepted accounting principles, and that a companys receipts and expenditures are being made only in accordance with authorizations of a companys management and directors, and (iii) provide reasonable assurance regarding prevention
or timely detection of unauthorized acquisition, use, or disposition of a companys assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurance with respect to consolidated financial statement preparation and
presentation and may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

As required by Section 404 of the Sarbanes-Oxley Act of 2002
and related rules as promulgated by the Securities and Exchange Commission, management assessed the effectiveness of our internal control over financial reporting as of December 31, 2012 using criteria established in Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on this assessment,
management concluded that our internal control over financial reporting was effective as of December 31, 2012 based on the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission.

The effectiveness of our internal control over financial reporting has been audited by
Deloitte & Touche, an independent registered public accounting firm, who has also audited our consolidated financial statements for the year ended December 31, 2012. Deloitte & Touche has issued an attestation report on the
effectiveness of our internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States).

Attestation Report of the Registered Public Accounting Firm

REPORT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of

Chunghwa Telecom Co., Ltd.

We
have audited the internal control over financial reporting of Chunghwa Telecom Co., Ltd. and subsidiaries (the Company) as of December 31, 2012, based on criteria established in Internal ControlIntegrated Framework issued by
the Committee of Sponsoring Organizations of the Treadway Commission. The Companys management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control
over financial reporting, included in the accompanying Managements Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Companys internal control over financial
reporting based on our audit.

##### Table of Contents

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing
such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed by, or under the supervision of, the companys principal executive and principal financial officers, or persons
performing similar functions, and effected by the companys board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with
generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or
fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our
opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal ControlIntegrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with auditing standards generally
accepted in the Republic of China and the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2012 of the Company and our report dated
April 10, 2013 expressed an unqualified opinion on those financial statements and included explanatory paragraphs regarding i) the reconciliation to accounting principles generally accepted in the United States of America (U.S.
GAAP) and ii) the convenience translation of New Taiwan dollar amounts into U.S. dollar amounts.

|ITEM 16G. | CORPORATE GOVERNANCE
|--------- | --------------------

As
a ROC company listed on the New York Stock Exchange, or NYSE, we are subject to the U.S. corporate governance rules to the extent that these rules are applicable to foreign private issuers. The following summary details the significant differences
between our corporate governance practices and corporate governance standards for non-foreign private issuers (e.g., U.S. companies) under the NYSE Listed Company Manual.

Under Section 303A of the NYSE Listed Company Manual, NYSE-listed foreign private issuers may, in general, follow their home country corporate governance practices in lieu of most of the new NYSE
corporate governance requirements. However, all NYSE-listed foreign private issuers must comply with Sections 303A.06, 303A.11, 303A.12(b) and 303A.12(c) of the NYSE Listed Company Manual.

The Legal Framework. In general, corporate governance principles for Taiwanese companies are set forth in the Company Act of the
Republic of China, or ROC Company Act, the ROC Securities Exchange Act, regulations promulgated by the Securities and Futures Bureau of the Financial Supervisory Commission and, to the extent they are listed on the TWSE, listing rules of the TWSE.
Corporate governance principles under provisions of ROC law may differ in significant ways to corporate governance standards for non-foreign private issuers listed on the NYSE. Committed to high standards of corporate governance, we have generally
brought our corporate governance in line with U.S. regulations, including the formation of an audit committee. However, we have not adopted certain recommended NYSE corporate governance standards where such standards are not in conformity with ROC
laws or regulations or generally prevailing business practices in Taiwan. We believe the following to be the significant differences between our corporate governance practices and NYSE corporate governance rules applicable to non-foreign private
issuers listed on the NYSE.

Director Independence. The NYSE corporate governance rules applicable to non-foreign
private issuers listed on the NYSE require companies to have a majority of independent directors on the board of directors. The ROC Securities Exchange Act requires the independent directors of a public company to comprise of no less than one-fifth
of the board of directors. We currently have three independent directors on our twelve-member board of directors. Our standards for determining director independence, which comply with requirements under the ROC Company Act and ROC Securities
Exchange Act for director independence, may differ from the standards imposed by the NYSE.

In addition, under the ROC
requirements, our board of directors is not required to make a formal determination of a directors independence. Nevertheless, we believe that our independent directors are free from any business or other relationships that would impair the
exercise of their independent judgment. Furthermore, pursuant to the NYSE Listed Company Manual, non-executive directors must meet on a regular basis without the management directors present. All of our directors attend our board of directors
meetings; however, no separate meeting is held among non-executive directors.

Audit Committee. On April 1, 2003,
the SEC adopted final rules relating to the audit committee requirements. Foreign private issuers listed on the NYSE were required to comply with the related NYSE corporate governance rules by July 31, 2005. On February 20, 2013, the FSC
of the ROC announced that any (i) financial holding company, bank, bill finance company or insurance company, (ii) listed company whose paid-in capital reaches NT$50 billion or (iii) integrated securities firm controlled by a
financial holding company, should establish an audit committee to replace supervisors. See Item 6. Directors, Senior Management and EmployeesC. Board Practices for a discussion of our new audit committee starting from the date of
the annual general meeting in June 2013. As a result, we will simultaneously comply with the relevant rules of the NYSE Listed Company Manual and the relevant rules and regulations in the ROC.

##### Table of Contents

Our audit committee was established in September 2004 in accordance with the rules set forth
in the NYSE Listed Company Manual, and is comprised of three independent directors. According to the NYSE corporate governance rules applicable to non-foreign private issuers listed on the NYSE, the board must review status of any audit member that
serves on more than three audit committees. There is no such requirement under the ROC law, which allows a person to serve as an independent director on up to four public companies in the ROC.

Section 303A.07 of the NYSE Listed Company Manual requires issuers to have at least three directors on the audit committee that
meets the definition of independence set forth under Rule 10A-3 of the Exchange Act and Section 303A of the NYSE Listed Company Manual. There is no such requirement under the ROC law, which requires all independent directors of a public company
to be members of the audit committee if the company has established such a committee. See Item 6. Directors, Senior Management and EmployeesC. Board Practices.

Nominating/Corporate Governance Committee and Corporate Governance Principles. The NYSE corporate governance rules applicable to
non-foreign private issuers listed on the NYSE require companies to have a nominating/corporate governance committee, composed entirely of independent directors. In addition to identifying individuals qualified to become board members, the
nominating/corporate governance committee must develop and recommend to the board a set of corporate governance principles. The ROC Company Act does not require companies incorporated in the ROC to have a nominating/corporate governance committee.
We do not currently have a nominating committee or a corporate governance committee.

Currently, our board of directors
performs the duties of a corporate governance committee and regularly reviews our corporate governance principles and practices. The ROC Company Act requires that directors shall be elected by stockholders. Our articles of incorporation requires us,
beginning in the fifth commencement, to establish at least three independent directors in the number of directors. The elections for directors shall proceed with the candidate nomination system; the stockholders shall elect the directors from among
the nominees listed in the roster of director candidates. Stockholders holding stock over 1% are entitled to nominate candidates of directors in written to us. The numbers of candidates nominated by stockholders shall not exceed the numbers of
directors to be elected; neither the numbers of candidates nominated by the Board. Elections for independent and non-independent directors shall proceed concurrently, and the number of elected independent and non-independent directors shall be
calculated separately.

Non-foreign private issuers listed on the NYSE are also required to adopt and disclose corporate
governance guidelines. We currently comply with the ROC Non-Binding Corporate Governance Best-Practice Principles for TSEC/GTSM Listed Companies promulgated by the TWSE, or Best-Practice Principles, and we provide an explanation of differences
between our practice and the principles, if any, in our ROC annual report.

Compensation Committee. The NYSE corporate
governance rules applicable to non-foreign private issuers listed on the NYSE require companies to have a compensation committee, composed entirely of independent directors. The Article 14-6 of ROC Securities and Exchange Act requires all listed
companies to establish a compensation committee for directors, supervisors and managers compensation, which includes salary, stock options and other rewards, as well as authorizes the Competent Authority (i.e. Financial Supervisory Commission)
to enact a regulation on the authorities of the compensation committee and the qualifications of its members. See Item 6. Directors, Senior Management and EmployeesC. Board Practices for description of our compliance.

Code of Business Conduct and Ethics. The NYSE corporate governance rules applicable to non-foreign private issuers listed on the
NYSE require companies must adopt a code of business conduct and ethics for directors, officers and employees and promptly disclose any waivers of the code for directors or executive officers. We have adopted Code of Ethics and Ethical Corporate
Management Best Practice Principles that applies to our directors, supervisors, managers, employees and persons having substantial control over us. We have filed Code of Ethics and Ethical Corporate Management Best Practice Principles as an exhibit
to our annual report filed with the SEC and a copy is available to any stockholder upon request.

##### Table of Contents

Equity Compensation Plans. The NYSE corporate governance rules applicable to
non-foreign private issuers listed on the NYSE require that equity compensation plans be approved by a companys stockholders. Under the ROC Company Act and the ROC Securities and Exchange Act, stockholders approval is required for the
distribution of employee bonuses and any issuances of restricted stock to employees, while the board of director has authority to approve employee stock option plans and to grant options to employees pursuant to such plans, subject to the approval
of the Securities and Futures Bureau, Financial Supervisory Commission, and to approve share buy-back programs and transfer of shares to employees under such programs. We intend to follow only the ROC requirements.

Means to Communicate with Non-Management Directors. The NYSE corporate governance rules applicable to non-foreign private
issuers listed on the NYSE require companies to establish a means for stockholders, employees and other interested parties to communicate with non-management directors. The ROC law does not have comparable requirements. However, according to the
Best-Practice Principles, companies are required to establish channels of communication with employees and encourage employees to communicate directly with the management, directors or supervisors so as to reflect employees opinions about the
management, financial conditions and material decisions of the company concerning employee welfare. Moreover, companies are required to establish a channel for supervisors to communicate with the employees, stockholders, and interested parties. We
have complied with these provisions.

Internal Audit Function. The NYSE corporate governance rules applicable to
non-foreign private issuers listed on the NYSE require companies to establish an internal audit function to provide management and the audit committee with assessments of the companys risk management processes and system of internal control.
We have complied with the Best-Practice Principles by setting up an internal control/audit system in accordance with the ROC Regulations Governing Establishment of Internal Control Systems by Public Companies.

CEO Certification to the NYSE. The NYSE listing standards require the CEO of companies to certify compliance with NYSE
corporate governance standards annually. ROC law does not contain such requirement. In this regard, we only follow ROC corporate governance requirement which does not require CEO annual certification. However, our CEO and CFO are required to certify
in the 20-F annual report that, to his or her knowledge the information contained therein fairly represents in all material respects the financial condition and results of operation of our company.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Chunghwa Telecom Co., Ltd.

We have audited the
accompanying consolidated balance sheets of Chunghwa Telecom Co., Ltd. and subsidiaries (the Company) as of December 31, 2011 and 2012, and the related consolidated statements of income, changes in stockholders equity, and
cash flows for the years ended December 31, 2010, 2011 and 2012, 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.

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.

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, 2011 and 2012, and the results of their operations and their
cash flows for the years ended December 31, 2010, 2011 and 2012, in conformity with accounting principles generally accepted in the Republic of China.

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 34 to the consolidated financial statements.

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.

Treadway Commission and our report dated April 10, 2013 expressed an unqualified opinion on the Companys internal control over financial reporting.

CHUNGHWA TELECOM CO., LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS





|1. | GENERAL
|-- | -------

Chunghwa Telecom
Co., Ltd. (Chunghwa) was incorporated on July 1, 1996 in the Republic of China (ROC) pursuant to the Article 30 of the Telecommunications Act. Chunghwa is a company limited by shares and, prior to August 2000, was wholly
owned by the Ministry of Transportation and Communications (MOTC). Prior to July 1, 1996, the current operations of Chunghwa were carried out under the Directorate General of Telecommunications (DGT). The DGT was
established by the MOTC in June 1943 to take primary responsibility in the development of telecommunications infrastructure and to formulate policies related to telecommunications. On July 1, 1996, the telecom operations of the DGT were
spun-off to as Chunghwa which continues to carry out the business and the DGT continues to be the industry regulator.

As the
dominate telecommunications service provider of fixed-line and Global System for Mobile Communications (GSM) in the ROC, Chunghwa is subject to additional regulations imposed by the ROC.

Effective August 12, 2005, the MOTC had completed the process of privatizing Chunghwa by reducing the government ownership to below
50% in various stages. In July 2000, Chunghwa received approval from the Securities and Futures Commission (the SFC) for a domestic initial public offering and its common shares were listed and traded on the Taiwan Stock Exchange (the
TSE) on October 27, 2000. Certain of Chunghwas common shares had been sold, in connection with the foregoing privatization plan, in domestic public offerings at various dates from August 2000 to July 2003. Certain of
Chunghwas common shares had also been sold in an international offering of securities in the form of American Depository Shares (ADS) on July 17, 2003 and were listed and traded on the New York Stock Exchange (the
NYSE). The MOTC sold common shares of Chunghwa by auction in the ROC on August 9, 2005 and completed the second international offering on August 10, 2005. Upon completion of the share transfers associated with these offerings

|2. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|-- | ------------------------------------------

The accompanying consolidated financial statements were prepared in conformity with accounting principles generally accepted in the ROC (ROC GAAP). The significant accounting policies are
summarized as follows:

Principle of Consolidation

The Company accounts for business combinations in accordance with the requirements of the Statement of Financial Accounting Standards
No. 25, Business Combinations.

The accompanying consolidated financial statements include the accounts of all
directly and indirectly majority owned subsidiaries of the Company, and the accounts of investees in which the Companys ownership percentage is less than 50% but over which the Company has a controlling interest. All intercompany transactions
and balances are eliminated upon consolidation.

The consolidated financial statements for the year ended December 31,
2010 include the accounts of Chunghwa, SENAO, SIS, SIHK, CIYP, CHIEF, Unigate, CHIEF (HK), CIC, CHSI, Concord, GNSS (Shanghai), CHTG, DHT, SHE, LED, YYRP, CHTS, CHTJ, IFE, IESA, IEHK, CHI, CHPT, CHPT (US), CIHC, COI, New Prospect, Prime Asia and
CHC. The consolidated financial statements for the year ended December 31, 2011 include the accounts of Chunghwa, SENAO, SIS, SIHK, STF, SITS, SITJ, SEITS, CIYP, CHIEF, Unigate, CIC, CHSI, Concord, GNSS (Shanghai), CHTG, DHT, SHE, CEI, LED,
YYRP, CHTS, CHTJ, IISI, IESA, IEHK, CHI, CHPT, CHPT (US), CIHC, COI, New Prospect, Prime Asia, CHC, CTC, CHTV, CHST, and SFD. The accounts of IISI, IESA and IEHK were deconsolidated on June 24, 2011 (see Note 1). The consolidated financial
statements for the year ended December 31, 2012 include the accounts of Chunghwa, SENAO, SIS, SIHK, STF, SITS, SITJ, SEITS, CIYP, CHIEF, Unigate, CIC, CHSI, Concord, GNSS (Shanghai), CHTG, DHT, SHE, CEI, LED, YYRP, CHTS, CHTJ, CHI, CHPT, CHPT
(US), CIHC, COI, New Prospect, Prime Asia, CHC, CTC, JZIT, HXIT, CHTV, CHST, and SFD.

For foreign subsidiaries using their
local currency as their functional currency, assets and liabilities are translated into New Taiwan dollars at the exchange rates in effect on the balance sheet date; stockholders equity accounts are translated into New Taiwan dollars at
historical exchange rates and income statement accounts are translated into New Taiwan dollars at average exchange rates during the year.

Business Combination

Acquisitions are accounted for using the purchase
method of accounting. The cost of the acquisition is measured at the aggregate of the fair values, at the date of exchange, of assets given and liabilities incurred or assumed, by the Company in exchange for control of the acquiree, plus any costs
directly attributable to the business combination. The acquirees identifiable assets and liabilities are recognized at their fair values at the acquisition date.

Goodwill arising on acquisition is recognized as an asset and initially measured at cost, being the excess of the cost of the business combination over the Companys interest in the net fair value of
the identifiable net assets.

The interest of minority stockholders in the acquiree is initially measured at historical cost.

Foreign-currency Transactions

Foreign-currency transactions other than derivative contracts are recorded in New Taiwan dollars at the rates of exchange in effect when the transactions occur. Exchange gains or losses derived from
foreign-currency transactions or monetary assets and liabilities denominated in foreign currencies are recognized in earnings. At the balance sheet date, monetary assets and liabilities denominated in foreign currencies are revalued at prevailing
exchange rates with the resulting gains or losses recognized in earnings.



F-15



---

##### Table of Contents

At the balance sheet date, foreign-currency nonmonetary assets (such as equity instruments)
and liabilities that are measured at fair value are revalued using prevailing exchange rates. When a gain or loss on a nonmonetary item is recognized in stockholders equity, any exchange component of that gain or loss shall be recognized in
stockholders equity. Conversely, when a gain or loss on a non-monetary item is recognized in earnings, any exchange component of that gain or loss shall be recognized in earnings.

Foreign-currency nonmonetary assets and liabilities that are carried at cost continue to be stated at exchange rates at trade dates.

The financial statements of foreign equity investees and consolidated subsidiaries are translated into New Taiwan dollars at
the following exchange rates. Assets and liabilities - spot rates at year-end; stockholders equity - historical rates, income and expenses - average rates during the year.

The resulting translation adjustments of financial statements shall be recorded as cumulative translation adjustments, a separate
component of stockholders equity.

Accounting Estimates

Under above principles, certain estimates and assumptions have been used for the allowance for doubtful accounts, allowance for loss on
inventories, depreciation of property, plant and equipment, impairment of assets, bonuses to employees, directors and supervisors, pension cost, and income tax, etc. Actual results may differ from these estimates.

Current and Noncurrent Assets and Liabilities

Current assets include cash and cash equivalents, and those assets held primarily for trading purposes or to be realized, sold or consumed within one year from the balance sheet date. All other assets are
classified as noncurrent. Current liabilities are obligations incurred for trading purposes or to be settled within one year from the balance sheet date. All other liabilities are classified as noncurrent.

LED engages mainly in development of property for rent and sale. The assets and liabilities of LED related to property development within
its operating cycle, which is over one year, are classified as current items. Assets and liabilities related to property development over its operating cycle are classified as noncurrent items.

Cash Equivalents

Cash equivalents are commercial paper and treasury bills purchased with maturities of three months or less from the date of acquisition. The carrying amount approximates fair value.

Financial Assets and Liabilities at Fair Value Through Profit or Loss

Financial instruments classified as financial assets or financial liabilities at fair value through profit or loss (FVTPL)
include financial assets or financial liabilities held for trading and are designated as at FVTPL on initial recognition. The Company recognizes a financial asset or a financial liability when the Company becomes a party to the contractual
provisions of the financial instrument. A financial asset is derecognized when the Company losses control of its contractual rights over the financial asset. A financial liability is derecognized when the obligation specified in the relevant
contract is discharged, cancelled or expired.



F-16



---

##### Table of Contents

Financial instruments at FVTPL are initially measured at fair value. Transaction costs
directly attributable to the acquisition of financial assets or financial liabilities at FVTPL are recognized as expenses as incurred. Financial assets or financial liabilities at FVTPL are remeasured at fair value, subsequently with changes in fair
value recognized in earnings. Cash dividends received subsequently (including those received in the period of investment) are recognized as income. On derecognition of a financial asset or a financial liability, the difference between its carrying
amount and the sum of the consideration received and receivable or consideration paid and payable is recognized in earnings. Regular way purchases or sales of financial assets are accounted for using trade date accounting.

Derivatives that do not meet the criteria for hedge accounting are classified as financial assets or financial liabilities held for
trading. When the fair value is positive, the derivative is recognized as a financial asset; when the fair value is negative, the derivative is recognized as a financial liability.

Fair values of financial assets and financial liabilities at the balance sheet date are determined as follows: forward exchange contracts
and currency swap contracts are estimated by valuation techniques; index future contracts are determined at their market quotation on the balance sheet date; bonds are based on prices quoted by GreTai Securities Market (GTSM).

Available-for-sale Financial Assets

Available-for-sale financial assets are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition. Changes in fair value from subsequent remeasurement are
reported as a separate component of stockholders equity. The corresponding accumulated gains or losses are recognized in earnings when the financial asset is derecognized from the balance sheet. A regular way purchase or sale of financial
assets is accounted for using trade date accounting.

The recognition and derecognition of available-for-sale financial assets
are the same with those of financial assets at FVTPL.

Fair values are determined as follows: Listed stocks - at closing prices
at the balance sheet date; open-end mutual funds - at net asset values at the balance sheet date; bonds - quoted at prices provided by the Taiwan GreTai Securities Market; and financial assets and financial liabilities without quoted prices in an
active market - at values determined using valuation techniques.

Cash dividends are recognized in earnings on the ex-dividend
date, except for the dividends declared before acquisition which are treated as a reduction of investment cost. Stock dividends are recorded as an increase in the number of shares and do not affect investment income. The total number of shares
subsequent to the increase of stock dividends is used to recalculate cost per share. The difference between the initial carrying amount of a debt instrument and its maturity amount is amortized using the effective interest method, with the amortized
interest recognized in profit or loss.

An impairment loss is recognized when there is objective evidence that the financial
asset is impaired. If, in a subsequent period, the amount of the impairment loss decreases, for equity securities, the previously recognized impairment loss is reversed to the extent of the decrease and recorded as an adjustment to
stockholders equity; for debt securities, the amount of the decrease is recognized in earnings, provided that the decrease is clearly attributable to an event which occurred after the impairment loss was recognized.

Held-to-maturity Financial Assets

Held-to-maturity financial assets are carried at amortized cost using the effective interest method. Those financial assets are initially recognized at fair value plus transaction costs that are directly
attributable to the acquisition. Gains and losses are recognized at the time of derecognition, impairment or amortization. A regular way purchase or sale of financial assets is accounted for using trade date accounting.



F-17



---

##### Table of Contents

If there is objective evidence which indicates that a financial asset is impaired, a loss is
recognized. If, in a subsequent period, the amount of the impairment loss decreases and the decrease is clearly attributable to an event which occurred after the impairment loss was recognized, the previously recognized impairment loss is reversed
to the extent of the decrease. The reversal may not result in a carrying amount that exceeds the amortized cost that would have been determined as if no impairment loss had been recognized.

Financial Assets Carried at Cost

Investments in equity instruments with no quoted prices in an active market and with fair values that cannot be reliably measured, such as non-publicly traded stocks and stocks traded in the Emerging
Stock Market, are measured at their original cost. The accounting treatment for dividends on financial assets carried at cost is the same with that for dividends on available-for-sale financial assets. An impairment loss is recognized when there is
objective evidence that the asset is impaired. A reversal of this impairment loss is disallowed.

Impairment of Accounts
Receivable

An allowance for doubtful accounts is provided on the basis of a review of the collectibility of accounts
receivable before January 1, 2011. The Company assesses the probability of collections of accounts receivable by examining the aging analysis of the outstanding receivables and assessing the value of the collateral provided by customers.

On January 1, 2011, the Company adopted the third-time revised Statement of Financial Accounting Standards (SFAS)
No. 34, Financial Instruments: Recognition and Measurement. One of the main revisions is that the impairment of receivables originated by the Company should be covered by SFAS No. 34. Accounts receivable are assessed for
impairment at the end of each reporting period and considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the accounts receivable, the estimated future cash
flows of the asset have been affected.

The amount of the impairment loss recognized is the difference between the asset
carrying amount and the present value of estimated future cash flows, after taking into account the related collateral and guarantees, discounted at the receivables original effective interest rate.

The carrying amount of the accounts receivable is reduced through the use of an allowance account.

Inventories

Inventories including merchandise, work-in-process and raw materials are stated at the lower of cost (weighted-average cost) or net realizable value item by item, except for those that may be appropriate
to group items of similar or related inventories. Net realizable value is the estimated selling price of inventories less all estimated costs of completion and costs necessary to make the sale. The calculation of the cost of inventory is derived
using the weighted-average method.

Buildings and Lands Consigned to Constructing Firm

Inventories of LED are stated at the lower of cost or net realizable value item by item, except for those that may be appropriate to group
as similar items or related inventories. Land acquired before construction is classified as land held for development, and then reclassified as land held under development after LED begins its construction project. Prepayments for licensing and
other miscellaneous costs have been capitalized as part of inventory.

When using the completed-contract method for its
construction projects, LED recognizes the proceeds from customers as advances from customers for land and building before the construction project is completed. After completion of the construction project and ownership is transferred to the
customers, LED recognizes the relevant revenues.



F-18



---

##### Table of Contents

When using percentage-of-completion method, profits are recorded based on LEDs
estimates of the percentage of completion of individual contracts, commencing when the work performed under the contracts reaches a point where the final costs can be estimated with reasonable accuracy. Changes in job performance, job conditions and
estimated profitability may result in revisions to costs and income and are recognized in the period in which the revisions are determined. If the current estimates of total contract revenue and contract cost indicate a loss, a provision for the
entire loss on the contract is recorded in the period in which it becomes evident.

The percentage of completion is measured
based on the completion of the contract milestones predetermined by the architects and engineers. Construction in progress is stated at cost plus (less) amounts associated with estimated profit (loss) recognized on the basis of the
percentage-of-completion method.

Investments Accounted for Using Equity Method

Investments in companies in which the Company exercises significant influence over the operating and financial policy decisions are
accounted for by the equity method. Under the equity method, the investment is initially stated at cost and subsequently adjusted for its proportionate share in the net earnings of the investee companies. Any cash dividends received are recognized
as a reduction in the carrying value of the investments.

Gains or losses on sales from the Company to equity method investees
wherein Chunghwa exercises significant influence over these equity method investees are deferred in proportion to the Companys ownership percentage in the investees until such gains or losses are realized through transactions with third
parties. Gains or losses on sales from equity method investees to Chunghwa are deferred in proportion to Chunghwas ownership percentages in the investees until they are realized through transactions with third parties.

The cost of an investment shall be analyzed and the cost of investment in excess of the fair value of identifiable net assets acquired,
representing goodwill, shall not be amortized. If the fair value of identifiable net assets acquired exceeds the cost of investment, the excess shall be proportionately allocated as reductions to fair values of non-current assets (except for
financial assets other than investments accounted for using the equity method and deferred income tax assets). When an indication of impairment is identified, the carrying amount of the investment is reduced, with the related impairment loss
recognized in earnings.

When the Company subscribes for additional investees shares at a percentage different from its
existing ownership percentage, the resulting carrying amount of the investment in the investee differs from the amount of the Companys share of the investees equity. The Company records such a difference as an adjustment to long-term
investments with the corresponding amount charged or credited to additional paid-in capital to the extent available, with the balance charged to retained earnings.

Property, Plant and Equipment

Property, plant and equipment are stated at
cost plus a revaluation increment, if any, less accumulated depreciation and accumulated impairment loss. The interest costs that are directly attributable to the acquisition, construction of a qualifying asset are capitalized as property, plant and
equipment. Major renewals and betterments are capitalized, while maintenance and repairs are expensed as incurred.

When an
indication of impairment is identified, any excess of the carrying amount of an asset over its recoverable amount is recognized as a loss. If the recoverable amount increases in a subsequent period, the amount previously recognized as impairment
would be reversed and recognized as a gain. However, the adjusted amount may not exceed the carrying amount that would have been determined, net of depreciation, as if no impairment loss had been recognized.



F-19



---

##### Table of Contents

An impairment loss on a revalued asset is charged to unrealized revaluation
increment under equity to the extent available, with the balance recognized as a loss in earnings. If the recoverable amount increases in a subsequent period, the amount previously recognized as impairment loss could be reversed and recognized
as a gain, with the remaining credited to unrealized revaluation increment.

Depreciation expense is computed using
the straight-line method over the following estimated service lives: land improvements - 2 to 30 years; buildings - 3 to 60 years; computer equipment - 2 to 15 years; telecommunication equipment - 2 to 20 years; transportation equipment - 3 to 10
years; and miscellaneous equipment - 2 to 12 years.

Upon sale or disposal of property, plant and equipment, the related cost,
accumulated depreciation, accumulated impairment losses and any unrealized revaluation increment are deducted from the corresponding accounts, and any gain or loss is recorded as non-operating gains or losses in the year of sale or disposal.

Intangible Assets

Intangible assets mainly included 3G Concession, computer software, patents and goodwill.

The 3G Concession is valid through December 31, 2018. The 3G Concession fee is amortized on a straight-line basis from the date operations commence through the date the license expires. Computer
software costs and patents are amortized using the straight-line method over the estimated useful lives of 2 to 20 years.

When
an indication of impairment is identified for intangible assets other than goodwill, any excess of the carrying amount of an asset over its recoverable amount is recognized as a loss. If the recoverable amount increases in a subsequent period, the
amount previously recognized as impairment would be reversed and recognized as a gain. However, the adjusted amount may not exceed the carrying amount that would have been determined, as if no impairment loss had been recognized.

Goodwill represents the excess of the consideration paid for business acquisition over the fair value of identifiable net assets acquired.
Goodwill is tested for impairment annually. If an event occurs or circumstances change which indicates that the fair value of goodwill is below its carrying amount, an impairment loss is recognized. A subsequent reversal of such impairment loss is
not allowed.

Idle Assets

Idle assets are carried at the lower of recoverable amount or carrying amount.

Pension Costs

Pension cost under a defined benefit plan is determined by actuarial valuations. Contributions made under a defined contribution plan are recognized as pension cost during the period in which employees
render services.

Income Tax

The Company applies inter-period allocations for its income tax, whereby deferred income tax assets and liabilities are recognized for the tax effects of temporary differences and unused tax credits.
Valuation allowances are provided to the extent, if any, that it is more likely than not that deferred income tax assets will not be realized. A deferred tax asset or liability is classified as current or noncurrent in accordance with the
classification of its related asset or liability. However, if a deferred tax asset or liability does not relate to an asset or liability in the financial statements, then it is classified as either current or noncurrent based on the expected length
of time before it is realized or settled.



F-20

##### Table of Contents

Any tax credits arising from purchases of machinery, equipment and technology, research and
development expenditures, personnel training, and investments in important technology based enterprises are recognized using the flow-through method.

Adjustments of prior years tax liabilities are added to or deducted from the current years tax provision.

Income taxes at 10% on undistributed earnings is recorded in the year of stockholders approval which is the year subsequent to the year the earnings are generated.

Share-based Compensation

Employee stock options granted on or after January 1, 2008 are accounted for using fair value method in accordance with SFAS No. 39, Accounting for Share-based Payment. Financial
Supervisory Commission (FSC) provided the two-year transition provision for unlisted companies to allow them to account for the options granted between January 1, 2008 to December 31, 2009 using intrinsic value method, under
which compensation cost was amortized over the vesting period. Employee stock options granted between January 1, 2004 and December 31, 2007 were accounted for under the interpretations issued by the Accounting Research and Development
Foundation (the ARDF). The Company adopted the intrinsic value method in accordance with the interpretations issued by the ARDF.

Revenue Recognition

Revenues are recognized when they are realized or
realizable and earned. Revenues are realized or realizable and earned when the Company has persuasive evidence of an arrangement, the goods have been delivered or the services have been rendered to the customers, the sales price is fixed or
determinable and collectibility is reasonably assured.

Revenue is measured at the fair value of the consideration received or
receivable and represents amounts agreed between the Company and the customers for goods sold in the normal course of business, net of sales discounts and volume rebates. For trade receivables due within one year from the balance sheet date, as the
nominal value of the consideration to be received approximates its fair value and transactions are frequent, fair value of the consideration is not determined by discounting all future receipts using an imputed rate of interest.

Usage revenues from fixed-line services (including local, domestic long distance and international long distance), cellular services,
Internet and data services, and interconnection and call transfer fees from other telecommunications companies and carriers are billed in arrears and are recognized based upon seconds or minutes of traffic processed when the services are provided in
accordance with contract terms.

Other revenues are recognized as follows: (a) one-time subscriber connection fees (on
fixed-line services) are deferred and recognized over the average expected customer service periods, (b) monthly fees (on fixed-line, mobile, Internet and data services) are accrued every month, and (c) prepaid services (fixed-line,
mobile, Internet and data services) are recognized as income based upon actual usage by customers or when the right to use those services expires.

Where the Company enters into transactions which involve both the provision of air time bundled with products such as 3G data card and handset, total consideration received from handsets in these
arrangements are allocated and measured using units of accounting within the arrangement based on relative fair values limited to the amount that is not contingent upon the delivery of other items or services.

Where the Company sells products to third party cellular phone stores the Company records the direct sale of the products, typically
handsets, as gross revenue when the Company is the primary obligor in the arrangement and when title is passed and the products are accepted by the stores.

Expense Recognition

The costs of providing services and operating expenses are recognized as incurred.

Concentrations

For all periods presented, no individual customer or supplier constituted more than 10% of the Companys revenues, trade notes and accounts receivables, purchases or trade notes and accounts payable.
The Company invests its cash with several financial institutions. The Company also does not have concentrations of available sources of labor, services or other rights that could, if suddenly eliminated, severely impact its operations. However,
telecommunications franchises and licenses are issued solely by authority of the ROC government. The withdrawal or the revocation of the franchise and licenses by the ROC government would severely impact the Companys operations.

Earnings Per Share and Per Equivalent ADS

Earnings per share is computed by dividing net income attributable to stockholders of the parent by the weighted-average number of common shares outstanding during the periods. Earnings per equivalent ADS
is calculated by multiplying the above earnings per share by ten as each ADS represents ten common shares.

The Company entered into currency swap contracts, forward exchange contracts and index future contracts to
reduce its exposure to foreign currency risk and variability in operating results due to fluctuations in exchange rates and stock prices. However, the aforementioned derivatives did not meet the criteria for hedge accounting and were classified as
financial assets or financial liabilities held for trading.

The board of directors of Chunghwa resolved to acquire 263,622 thousand common shares of China
Airline Ltd. (CAL) at NT$11.73 per share in January 2012. Chunghwa expected to hold it as long-term investment and classified it as available-for-sale financial assets - noncurrent. CAL engages mainly in air transportation business.

After evaluating the available-for-sale financial assets, CHI determined that some investments were impaired and recognized an
impairment loss of NT$27 million for the year ended December 31, 2012.

Movements of unrealized gain (loss) on
available-for-sale financial assets were as follows:

InfoExplorer Co., Ltd. (IFE) issued new shares as the consideration to merge with
International Integrated System, Inc. and e-ToYou International, Inc. on April 1, 2011. After the merger, IFE became the surviving entity and was renamed as International Integrated System, Inc. (IISI). International Integrated
System, Inc. and e-ToYou International, Inc. were dissolved. As a result of the additional shares being issued by IFE in connection with this transaction, Chunghwas ownership interest in IISI decreased from 49% to 33% after the merger. After
the stockholders meeting of IISI on June 24, 2011, Chunghwa lost control of the board of directors. Due to this loss of control, IISI was deconsolidated and going forward the investment is accounted for as an equity method investment.

(Concluded)

Pursuant to the related regulation, Chunghwa revalued its land owned as of April 30, 2000 based on the publicly announced value on July 1, 1999. These revaluations which have been approved by
the Ministry of Auditing resulted in increases in the carrying values of property, plant and equipment of NT$5,986 million, liabilities for land value incremental tax of NT$211 million, and stockholders equity - other adjustments of NT$5,775
million.

The amendment to the Land Tax Act, relating to the article to permanently lower land value incremental tax, went
effective from February 1, 2005. In accordance with the lowered tax rates, Chunghwa recomputed its land value incremental tax, and reclassified the reserve for land value incremental tax of NT$116 million to stockholders equity - other
adjustments. As of December 31, 2012, the unrealized revaluation increment was decreased to NT$5,760 million by disposal of revaluation assets.

Chunghwa reclassified unused property, plant and equipment amounting to NT$61 million to idle assets and recognized the impairment loss of NT$61 million on those assets for the year ended
December 31, 2010. The Company did not recognize any property, plant and equipment impairment loss for the year ended December 31, 2011. In 2012, the Company determined that partial land and telecommunication equipment were impaired and
recognized an impairment loss of NT$1,505 million. Due to the impairment, the unrealized revaluation increment was decreased by NT$3 million. In 2012, idle asset and other asset - other recognized impairment losses of NT$35 million and NT$20
million, respectively.

Depreciation expense on property, plant and equipment was NT$32,737 million, NT$30,889 million and
NT$31,027 million for the years ended December 31, 2010, 2011 and 2012, respectively. Interest expense capitalized for the years ended December 31, 2010, 2011 and 2012 were NT$0.01 million, NT$0.08 million and NT$0.04 million,
respectively. The capitalized interest rates were 1.10%, 1.10%-1.25% and 1.22%-1.25%, respectively, for the years ended December 31, 2010, 2011 and 2012.

|22. | STOCKHOLDERS EQUITY
|--- | --------------------

Under Chunghwas Articles of Incorporation, Chunghwas authorized capital is NT$120,000,000 thousand, which is divided into
12,000,000 thousand common shares (at $10 par value per share), among which 7,757,447 thousand common shares are issued and outstanding as of December 31, 2012.

For the purpose of privatizing Chunghwa, the MOTC sold 1,109,750 thousand common shares of Chunghwa in an international offering of securities in the form of American Depositary Shares
(ADS) amounting to 110,975 thousand units (one ADS represents ten common shares) on the New York Stock Exchange on July 17, 2003. Afterwards, the MOTC sold 1,350,682 thousand common shares in the form of ADS amounting to
135,068 thousand units on August 10, 2005. Subsequently, the MOTC and Taiwan Mobile Co., Ltd. sold 505,389 thousand and 58,959 thousand common shares of Chunghwa, respectively, in the form of ADS totally amounting to
56,435 thousand units on September 29, 2006. The MOTC and Taiwan Mobile Co., Ltd. have sold 3,024,780 thousand common shares in the form of ADS amounting to 302,478 thousand units. As of December 31, 2012, the outstanding
ADSs representing 309,211 thousand common shares, which equaled approximately 30,921 thousand units and represented 3.99% of Chunghwas total outstanding common shares.

The ADS holders generally have the same rights and obligations as other common stockholders, subject to the provision of relevant laws.
The exercise of such rights and obligations shall comply with the related regulations and deposit agreement, which stipulate, among other things, that ADS holders can, through deposit agents:



| | a. | Exercise their voting rights,
| | -- | -----------------------------



| | b. | Sell their ADSs, and
| | -- | --------------------



| | c. | Receive dividends declared and subscribe to the issuance of new shares.
| | -- | -----------------------------------------------------------------------

Under the ROC Company Law, additional paid-in capital may only be utilized to offset deficits. However, the additional paid-in capital from shares issued in excess of par and donations may be capitalized,
which however is limited to a certain percentage of Chunghwas paid-in capital. However, where a company undergoes an organizational change (such as a merger, acquisition, or reorganization) that results in the capitalization of undistributed
earnings after the organizational change, the above restriction does not apply. Under the revised Company Law issued on January 4, 2012, the aforementioned additional paid-in capital may also be distributed in cash. The additional paid-in
capital from long-term investments may not be used for any purpose.

In addition, before distributing a dividend or making any

If the initial accrual amounts of the aforementioned bonus are significantly different from
the amounts proposed by the board of directors, the difference is charged to the earnings of the year making the initial estimate. Otherwise, the difference between initial accrual amount and the amount resolved in the shareholders meeting is
charged to the earnings of the following year as a result of change in accounting estimate.

Under the ROC Company Law, the
appropriation for legal reserve shall be made until the accumulated reserve equals the aggregate par value of the outstanding capital stock of Chunghwa. This reserve can only be used to offset a deficit, or, under the revised Company Law issued on
January 4, 2012, when the legal reserve has exceeded 25% of the Companys paid-in capital, the excess may be transferred to capital or distributed in cash.

The appropriations and distributions of the 2010 and 2011 earnings of Chunghwa have been approved by the stockholders on June 24, 2011 and June 22, 2012 as follows:

No compensation cost was recognized under the intrinsic value method for the years ended
December 31, 2010, 2011 and 2012. Had SENAO used the fair value method to recognize the compensation cost, there were no significant impact on the consolidated net income and earnings per share.

Had SENAO used the fair value method to evaluate the options using the Black-Scholes model, the assumptions used to calculate the share

Risk-free interest rate is based on the rate of the Taiwan government bonds in effect at the time of
grant. Expected volatilities are based on historical volatilities of stock prices of the similar companies in the same industry and SENAO. Expected life represents the period that SENAOs share-based awards are expected to be outstanding and
was determined based on historical experience regarding similar awards, giving consideration to the contractual term of the share-based awards. The dividend yield is zero as there are dividend protection rights in SENAOs option plans with the
exception of the options granted in 2007. The expected dividend yield for SENAOs 2007 Plan is based on anticipated future cash dividends yield at the time of grant.

The board of SENAO resolved to authorize 10,000 thousand units of stock options on May 2, 2012. Each option is eligible to subscribe for one common share when exercisable. The aforementioned
share-based compensation plan (2012 Plan) was effectively approved by FSC on May 28, 2012. Under the terms of the 2012 Plan, the options are granted at an exercise price equal to the closing price of the SENAOs common shares listed on the
TSE on the higher of closing price or par value on the grant date. The 2012 Plan has exercise price adjustment formula upon the issuance of new common shares, capitalization of retained earnings and/or capital reserves, stock split as well as
distribution of cash dividends, except (i) in the case of issuance of new shares in connection with mergers and in the case of cancellation of outstanding shares in connection with capital reduction, and (ii) except if the exercise price
after adjustment exceeds the exercise price before adjustment. The options are valid for six years and based on the graded vesting schedule, 50% of option granted will vest two years after the grant date and another two tranches of 25% will vest
three and four years after the grant date, respectively. Up to date, SENAO has not granted options to employees.

CHPT granted 1,000 options to some of its employees in December 2008. Under the terms of CHPT Plan, each
option entitles the holder to subscribe for one thousand common shares when exercisable. The options are valid for 5 years and based on the graded vesting schedule, two tranches of 30% of option will vest two and three years after the grant date,
respectively, and the rest of 40% will vest four years after the grant date. There is exercise price adjustment formula upon the issuance of new common shares, capitalization of retained earnings and/or capital reserves, stock split, issuance of new
shares in connection with mergers, issuance of global depositary receipts as well as distribution of cash dividends, except if the exercise price after adjustment exceeds the exercise price before adjustment.

Risk-free interest rate is based on the rate of the Taiwan government bonds in effect at the time of
grant. Expected volatilities are based on historical volatilities of stock prices of the similar companies in the same industry and CHPT. Expected life represents the period that CHPTs share-based awards are expected to be outstanding and was
determined based on historical experience regarding similar awards, giving consideration to the contractual term of the share-based awards. The dividend yield is zero as there are dividend protection rights in CHPTs option plans with the
exception of the options granted in 2008. The expected dividend yield for CHPTs 2008 Plan is based on anticipated future cash dividends yield at the time of grant.

According to the Interpretation 97-169 issued by ARDF in May 2008, Chunghwa presumed that the employee
bonuses to be paid will be settled in shares and takes those shares into consideration when calculating the weighted average number of outstanding shares used in the calculation of diluted EPS if the shares have a dilutive effect for the years ended
December 31, 2010, 2011 and 2012. The number of shares is calculated by dividing the amount of bonuses by the closing price of the Chunghwas shares as of the balance sheet date. The dilutive effect of the shares needs to be considered
until the stockholders resolve the number of shares to be distributed to employees in their meeting in the following year.

|27. | PENSION PLANS
|--- | -------------

Chunghwa
completed privatization plans on August 12, 2005. Chunghwa is required to pay all accrued pension obligations including service clearance payment, lump sum payment under civil service plan, additional separation payments, etc. upon the
completion of the privatization in accordance with the Statute Governing Privatization of Stated-owned Enterprises. After paying all pension obligations for privatization, the plan assets of Chunghwa should be transferred to the Fund for
Privatization of Government-owned Enterprises (the Privatization Fund) under the Executive Yuan. On August 7, 2006, Chunghwa transferred the remaining balance of fund to the Privatization Fund. However, according to the instructions
of MOTC, Chunghwa is requested to pay all accrued pension obligations including service clearance payment, lump sum payment under civil service plan, additional separation payments, etc. upon the completion of the privatization.

The pension plan under the Labor Pension Act of ROC (the LPA) is considered as a defined contribution plan. Based on the LPA,
Chunghwa and its subsidiaries make monthly contributions to employees individual pension accounts at 6% of monthly salaries and wages.

The Companys pension plan is considered as a defined benefit plan under the Labor Standards Law that provide benefits based on an employees length of service and average six-month salary prior
to retirement. Chunghwa and its subsidiaries contribute an amount no more than 15% of salaries paid each month to their respective pension funds (the Funds), which are administered by the Labor Pension Fund Supervisory Committee (the Committee) and
deposited in the names of the Committees in the Bank of Taiwan.

The Company used December 31 as the measurement date for
their pension plans.

Pension costs of the Company were NT$2,982 million (NT$2,752 million subject to defined benefit plan and
NT$230 million subject to defined contribution plan), NT$3,057 million (NT$2,810 million subject to defined benefit plan and NT$247 million subject to defined contributed plan) and NT$3,212 million (NT$2,901 million subject to defined benefit plan
and NT$311 million subject to defined contributed plan), for the years ended December 31, 2010, 2011 and 2012, respectively.

Pension information of the Company of the defined benefit plan is summarized as follows:

The increase of benefit paid as of December 31, 2012 was mainly attributed to Chunghwa approved a
Special Retirement Incentive Program in July 2012. The program allowed eligible employees who voluntarily applied to leave Chunghwa starting September 1, 2012 to receive special termination benefits. The cost of providing special termination
benefits recognized during the period was NT$1,126 million, and NT$601 million was paid by plan assets.

| | f. | A commitment to contribute NT$2,000 million to a Piping Fund administered by the Taipei City Government, of which NT$1,000 million was contributed by Chunghwa on
August 15, 1996 (classified as long-term investment - other monetary assets). If the fund is not sufficient, Chunghwa will contribute the remaining NT$1,000 million upon notification from the Taipei City Government. Based on terms of
Construction Funding Agreement, if the project is considered to be no longer necessary by the ROC government, Chunghwa will receive back its proportionate share of the net equity of the Piping Fund upon its dissolution. The Company does not know
when its contribution to the Piping Fund will be returned; therefore, the Company did not discount the face amount of its contribution to the Piping Fund.

| | b. | Methods and assumptions used in the estimation of fair values of financial instruments:
| | -- | ---------------------------------------------------------------------------------------



| | 1) | The fair values of certain financial instruments recognized in the balance sheet generally correspond to the market prices of the financial assets. Because of the short
maturities of these instruments, the carrying value represents a reasonable basis to estimate fair values. This method does not apply to the financial instruments discussed in Notes 2, 3, and 4 below.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2) | If the financial instruments have quoted market prices in an active market, the quoted market prices are viewed as fair values. If the market price of the other
financial instruments are not readily available, valuation techniques are used incorporating estimates and assumptions that are consistent with prevailing market conditions.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3) | Financial assets carried at cost are investments in unlisted shares, which have no quoted prices in an active market and entail an unreasonably high cost to obtain
verifiable fair values. Therefore, no fair value is presented.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4) | The fair value of long-term loans (including current portion) is discounted based on projected cash flow which approximate their carrying amounts. The projected cash
flows were discounted using the interest rate of similar long-term loans.

| | d. | Information about financial risks
| | -- | ---------------------------------



| | 1) | Market risk
| | -- | -----------

The foreign
exchange rate fluctuations would result in the Companys foreign-currency-dominated assets and liabilities, outstanding currency swap contracts, and forward exchange contracts exposed to rate risk.

The fluctuations of market price would result in the index future contracts exposed to price risk.

The financial instruments categorized as available-for-sale financial assets are mainly listed stocks, open-end mutual funds and
corporate bonds. Therefore, the market risk is the fluctuations of market price. In order to manage this risk, the Company would assess the risk before investing; therefore, no material market risk is anticipated.



| | 2) | Credit risk
| | -- | -----------

Credit risk
represents the potential loss that would be incurred by the Company if the counter-parties or third-parties breached contracts. Financial instruments with positive fair values at the balance sheet date are evaluated for credit risk. The
counter-parties or third-parties of the aforementioned financial instruments are reputable financial institutions and corporations. Management does not expect the Companys exposure to default by those parties to be material. The Company held a
variety of financial instruments. The maximum credit exposure of the aforementioned financial instruments is equal to their carrying amounts.



| | 3) | Liquidity risk
| | -- | --------------

The Company has
sufficient operating capital to meet cash needs upon settlement of derivative financial instruments. Therefore, the liquidity risk is low.

##### Table of Contents

The financial instruments of the Company categorized as open-end mutual funds, beneficiary
certificates and domestic listed stocks are publicly-traded, easily converted to cash. Therefore, no material liquidity risk is anticipated. The financial instruments categorized as financial assets carried at cost are investments that do not have a
quoted market price in an active market. Therefore, material liquidity risk is anticipated.



| | 4) | Cash flow interest rate risk
| | -- | ----------------------------

The Company engages in investments in fixed-interest-rate debt securities. Therefore, cash flows from such securities are not expected to
fluctuate significantly due to changes in market interest rates.



| | e. | Fair value hedge
| | -- | ----------------

Chunghwa
entered into currency swap contracts to hedge the fluctuation in exchange rates of beneficiary certificates denominated in foreign currency, which is fair value hedge. No transaction met the criteria for hedge accounting for the years ended
December 31, 2010, 2011 and 2012.

business. The five reporting segments are segregated as below: Domestic fixed communications business, mobile communications business, internet business, international fixed communications business and others.

|34. | SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES FOLLOWED BY THE COMPANY AND GENERALLY ACCEPTED ACCOUNTING PRINCIPLES IN THE UNITED STATES OF AMERICA
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

The accompanying financial statements have been prepared in accordance with accounting principles generally
accepted in the Republic of China (ROC GAAP), which differ in the following respects from accounting principles generally accepted in the United States of America (US GAAP):



| | a. | Property, plant and equipment
| | -- | -----------------------------

Under ROC GAAP, property, plant and equipment, excluding land, may be revalued when the price fluctuation is greater than 25% and upon
approval from the tax authority. Similarly, land may be revalued if there is any appreciation of land based on the value of land announced by the government. This revaluation is recorded as an unrealized revaluation increment under
equity at the time of revaluation and is subsequently depreciated. Upon sale or disposal of property, plant and equipment, the cost and any related unrealized revaluation increment less accumulated depreciation calculated after the revaluation are
removed from the accounts, and any gain or loss is credited or charged to income. An impairment loss on a revalued asset is charged to unrealized revaluation increment to the extent available with the balance recognized as a loss in
earnings. If the recoverable amount increases in the subsequent period, the amount previously recognized as an impairment loss could be reversed and recognized as a gain, with the remaining credited to unrealized revaluation increment.
This revaluation adjustment also created differences in the opening balances of additional paid-in capital upon incorporation of the Company on July 1, 1996.

Under US GAAP, no revaluation of property, plant and equipment is permitted.



| | b. | 10% tax on unappropriated earnings
| | -- | ----------------------------------

In ROC, a 10% tax is imposed on unappropriated earnings (excluding earnings from foreign consolidated subsidiaries). Under ROC GAAP, the Company records the 10% tax on unappropriated earnings in the year
of stockholders approval.

Under US GAAP, the 10% tax on unappropriated earnings is accrued during the period the
earnings

arise and adjusted to the extent that distributions are approved by the stockholders in the following
year.

| | c. | Deferred income from prepaid phone cards
| | -- | ----------------------------------------

Prior to incorporation and privatization, the Company was subject to the laws and regulations applicable to state-owned enterprises in Taiwan which differed from ROC GAAP as applicable to commercial
companies. As such, revenue from selling prepaid phone cards was recognized at the time of sale by the Company. Upon incorporation, net assets greater than capital stock was credited as additional paid-in capital. Part of additional paid-in capital
was from unearned revenues generated from prepaid cards as of that day. Upon privatization, unearned revenue generated from prepaid cards was deferred at the time of sale and recognized as revenue as consumed in accordance with ROC GAAP.

Under US GAAP, revenue from prepaid cards is deferred at the time of sale and recognized as revenue as consumed.

The GAAP adjustments related to prepaid cards subsequent to privatization are: (1) adjustments for prepaid cards transaction before
incorporation from additional paid-in capital and (2) adjustments for such transactions occurred between incorporation and privatization from retained earnings which still have remaining expected customer service periods.



| | d. | One-time connection fees income
| | -- | -------------------------------

Similar to prepaid phone cards, according to the laws and regulations applicable to state-owned enterprises in Taiwan, the Company
recorded revenue from providing fixed line connection service at the time the service was performed. Upon incorporation, net assets greater than capital stock was credited as additional paid-in capital. Part of additional paid-in capital was from
unearned revenues from connection fees as of that date. Upon privatization, unearned revenue generated from one-time connection fees was deferred at the time of service performed and recognized as revenue over time as the service is continuously
performed in accordance with ROC GAAP.

Under US GAAP, following the revenue recognition guidance, the above service
revenue should be treated as deferred income at the time of service rendered and the recognition of revenue should occur over time as the service is continuously performed.

The GAAP adjustments related to one-time connection fees income subsequent to privatization are: (1) adjustments for one time connection fees before incorporation from additional paid-in capital, and
(2) adjustments for such transactions occurred between incorporation and privatization from retained earnings which still have remaining expected customer service periods.



| | e. | Share-based compensation
| | -- | ------------------------



| | 1) | The Companys major stockholder, the MOTC made an offer to the Companys employees to purchase shares of common stock of the Company at a discount from the
quoted market price in 2006.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under ROC GAAP, such an offer was regarded as a transaction between stockholders
and no entry was recorded on the Companys books and records.

Under US GAAP, the offer was deemed as compensation
expense to employees and measured as the difference between the fair value of common stock offered and the amount of the discounted price at the grant date in 2006.

| | 2) | The Companys subsidiaries, SENAO and CHPT granted options to employees.
| | -- | ------------------------------------------------------------------------

Under ROC GAAP, employee stock options granted on or after January 1, 2008 are accounted for using fair value method in accordance with SFAS No. 39, Accounting for Share-based
Payment. Financial Supervisory Commission (FSC) provided the two-year transition provision for unlisted companies to allow them to account for the options granted between January 1, 2008 to December 31, 2009 using
intrinsic value method, under which compensation cost was amortized over the vesting period. Employee stock options granted between January 1, 2004 and December 31, 2007 were accounted for under the interpretations issued by the Accounting
Research and Development Foundation (the ARDF). The Company adopted the intrinsic value method in accordance with the interpretations issued by the ARDF.

Under US GAAP, the Company recognized compensation expense for such employee stock options granted by its subsidiary using the fair value method in accordance with the share-based payment guidance.



| | f. | Defined benefit pension plan
| | -- | ----------------------------

Pension accounting under ROC GAAP is similar in many respects to US GAAP. However, under ROC GAAP, companies are not required to recognize
the overfunded or underfunded positions of their defined benefit pension plans as an asset or liability on the balance sheet.

Under US GAAP, employers are required to recognize the overfunded or underfunded status of a defined benefit pension plan as an asset
or liability on its balance sheet and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. US GAAP defines the funded status of a benefit plan as the difference between the fair value
of the plan assets and the projected benefit obligation (PBO). Previously unrecognized items such as unrealized actuarial loss, unrecognized prior service cost and unrecognized net transition obligation are recognized in other
comprehensive income and are subsequently recognized through net periodic benefit cost.

Furthermore, the accounting treatment
of settlements and curtailments are different under ROC GAAP and US GAAP. Under ROC GAAP, settlement/curtailment gains or losses are equal to the changes of underfunded status plus a pro rata portion of the unrecognized prior service cost,
unrecognized net gains (losses), and unrecognized transition obligations/assets, before the settlement/curtailment event multiplied by the percentage reduction in PBO.

Under US GAAP, settlement gain (loss) is the total unrecognized net gain or losses including any gain or loss that arose from the measurement at the settlement date and unrecognized transition assets
before settlement multiplied by the percentage reduction in PBO. Curtailment gain (loss) includes the following items: (1) total unrecognized prior service cost and net transition obligation before curtailment multiplied by the curtailment
ratio (the ratio of reduction in future service over such future service before curtailment) and (2) decrease in PBO to the extent that such gain exceeds the net unrecognized loss (sum of unrecognized net gain or loss and net unrecognized
transition asset before curtailment) or the entire gain if a net unrecognized gain exists or increase in PBO to the extent that such loss exceeds unrecognized gain (sum of unrecognized net gain or loss and net unrecognized transition asset before
curtailment) or the entire loss if net unrecognized loss exists.



| | g. | Pension plan upon privatization
| | -- | -------------------------------

In order to improve operational efficiency, the Company approved several special retirement incentive programs during the process of
privatization.

Under ROC GAAP, the obligation related to annuity payments due after the date of
privatization for civil service eligible employees who retire prior to that date would be born by the MOTC. The Company completed its privatization plan on August 12, 2005. On the date of privatization, the MOTC settled all employees past
service costs. The portion of the pension obligations that was settled by the MOTC, represented by the difference between the accrued pension liabilities and the deferred pension cost as an adjustment for the pension cost of that year.

Under US GAAP, the MOTC settled related pension obligations on the privatization date and recorded the difference between accrued
pension liabilities, deferred pension cost and related deferred income tax assets, as contributed capital in stockholders equity.



| | h. | Income tax
| | -- | ----------

This line item
includes the tax effects of the pre-tax ROC GAAP to US GAAP adjustments described above.



| | i. | Noncontrolling interests of acquired subsidiaries
| | -- | -------------------------------------------------

The adjustment to net income for the years ended December 31, 2010 and to stockholders equity as of December 31, 2010, 2011 and 2012 represents a difference between ROC GAAP and
US GAAP for the accounting for business combinations.

Under ROC GAAP, the noncontrolling interest in the acquiree is
measured at historical cost whereas under US GAAP, the noncontrolling interest in the acquiree is measured at fair value at acquisition date upon the adoption of the new accounting standard beginning from January 1, 2009. Such adjustment
for the years ended December 31, 2009 and 2010 was caused by the Companys acquisition of IFE in January 2009 and of CHI in September 2009. The adjustment to ROC GAAP net income represents additional depreciation and amortization expenses
recognized under US GAAP due to the difference between the measurement of noncontrolling interests at historical cost and fair value. The adjustment to stockholders equity represents the difference for the measurement of noncontrolling
interests at historical cost and fair value after the aforementioned net income adjustment.

Under ROC GAAP, the Company is not
required to present items of other comprehensive income in statements of income. There is no term defined as other comprehensive income, although such other comprehensive income components are presented in the equity section. Under US GAAP, an
entity is required to present items of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements. The Company currently presented the statement of comprehensive income separately under US
GAAP and certain accounts have been reclassified to conform to the US GAAP presentation requirement.

The following is a
reconciliation of consolidated net income and stockholders equity under ROC GAAP as reported in the consolidated financial statements to the consolidated net income and equity determined under US GAAP, giving effect to the differences
listed above.

The Company applies ROC SFAS No. 17, Statement of Cash Flows. Its objectives and
principles are similar to those set out in U.S. standards. The principal differences between the two standards relate to classification. Cash flows from investing activities for changes in other assets, and cash flows from financing activities for
changes in customers deposits, other liabilities are reclassified to operating activities under U.S. standards. In addition, the effect of change on consolidated subsidiaries, which was shown as a separate item under ROC standards, is
reclassified to investing activities under U.S. standards. Summarized cash flow data by operating, investing and financing activities in accordance with U.S. standards are as follows:

|35. | ADDITIONAL DISCLOSURES REQUIRED BY US GAAP
|--- | ------------------------------------------



| | a. | Transition to IFRS in 2013
| | -- | --------------------------

As
of January 1, 2013, the Company began preparing its financial statements in accordance with International Financial Reporting Standards, International Accounting Standards, and relevant Interpretations (collectively, IFRSs) as
issued by International Accounting Standards Board (IASB) and IFRSs as endorsed for use in R.O.C. Its transition date to IFRSs was January 1, 2012. Therefore, the Companys 2012 consolidated financial statements under IFRSs may
be materially different from the accompanied 2012 consolidated financial statements under R.O.C. GAAP.



| | b. | Recent accounting pronouncements
| | -- | --------------------------------

In May 2011, the Financial Accounting Standards Board (FASB) issued an accounting update to amend the fair value measurement guidance and
include some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The standard is effective for the Company for the year ended
December 31, 2012. The Company has included these new disclosure, as applicable, in Note 35 (e).

In June and December
2011, the FASB issued accounting updates to eliminate the current option to report other comprehensive income and its components in the statement of stockholders equity. Instead, an entity will be required to present items of net income and
other comprehensive income in one continuous statement or in two separate, but consecutive, statements. The new requirements do not change which components of comprehensive income are recognized in net income or other comprehensive income, or when
an item of other comprehensive income must be reclassified to net income. The standard is effective for the Company for the year ended December 31, 2012. The Company has reported other comprehensive income and its components in two separate but
consecutive statements and the adoption did not have an impact on its results of operations, financial position or cash flows.

In September 2011, the FASB issued an accounting update, which is intended to reduce the cost and complexity of the annual goodwill
impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. Specifically, an entity has the option to first assess qualitative factors to determine
whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the
quantitative impairment test is required. Otherwise, no further testing is required. This standard is effective for the Company for the year ended December 31, 2012. The adoption of this guidance did not have a material impact on the
Companys results of operations, financial position or cash flows.

In December 2011, the FASB issued an accounting
update, which creates new disclosure requirements regarding the nature of an entitys rights of setoff and related arrangements associated with its financial instruments and derivative instruments. Certain disclosures of the amounts of certain
instruments subject to enforceable master netting arrangements or similar agreements would be required, irrespective of whether the entity has elected to offset those instruments in the statement of financial position. The disclosure requirements
are effective for annual reporting periods beginning on or after January 1, 2013 with retrospective application required. Since the Company started to adopt IFRS in 2013, it will not adopt this standard.

In February 2013, the FASB issued an accounting update requiring entities to present information about significant items reclassified out
of accumulated other comprehensive income (loss) by component either on the face of the statement where net income is presented or as a separate disclosure in the notes to the financial statements. This standard is effective for the Company for the
year ending December 31, 2013. Since the Company started to adopt IFRS in 2013, it will not adopt this standard.

| | c. | Share-based compensation
| | -- | ------------------------

The
Company adopted share-based compensation guidance to recognize compensation cost of options granted by SENAO and CHPT. The guidance requires companies to estimate the fair value of share-based payment awards on the date of grant using an
option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service period. The Company has estimated the fair value of stock options as of the date of grant
using the Black-Scholes option pricing model.

The compensation expenses related to stock options were NT$5 million, NT$2
million and NT$3 million for 2010, 2011 and 2012, respectively. There is no income tax effect related to share-based compensation arrangements.

SENAO

The weighted average remaining contractual term and aggregate
intrinsic value of options of SENAO under the foregoing plans as of December 31, 2012 were as follows:



|                    |  |                                         |      |  |                         |  |    |

|                    |  | WeightedAverageRemainingContractualTerm |      |  | AggregateIntrinsicValue | 
|                    |  | (In Years)                              |      |  | NT$(In Millions)        | 
|                    |  |                                        
|Options outstanding |  |                                         | 0.92 |  |                         |  | 70 | 
|Options exercisable |  |                                         | 0.92 |  |                         |  | 70 | 

The aggregate intrinsic value in the above table represents the total intrinsic value (the difference
between the Companys closing stock price on the last trading day of fiscal year 2012 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised
their options on December 31, 2012. Intrinsic value will change in future periods based on the fair market value of the Companys stock and the number of shares outstanding.

SENAO did not grant any options in 2010, 2011 and 2012.

Total intrinsic values of options exercised for the years ended December 31, 2010, 2011 and 2012 were NT$110 million, NT$193 million and NT$70 million, respectively. Total fair values of shares
vested during the years ended December 31, 2010, 2011 and 2012 were NT$164 million, NT$204 million and NT$103 million, respectively.

As of December 31, 2012, there was no unrecognized compensation expense related to share-based compensation plan.

The aggregate intrinsic value in the above table represents the total intrinsic value (the difference
between the fair value of shares and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2012. Intrinsic value
will change in future periods based on the audited Companys share in investees net assets and the number of shares outstanding.

CHPT did not grant any options in 2010, 2011 and 2012.

Total intrinsic value of
options exercised for the years ended December 31, 2010, 2011 and 2012 was nil. Total fair values of shares vested during the years ended December 31, 2010, 2011 and 2012 were nil, nil and NT$3 million, respectively.

As of December 31, 2012, there was no unrecognized compensation expense related to share-based compensation plan.

##### Table of Contents

The gross unrealized losses related to mutual funds, foreign listed stocks and corporate
bonds were due to fair value fluctuations. The Company reviewed its investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors that were considered in determining whether a loss is
other-than-temporary included but were not limited to, the length of time and extent to which fair value has been less than the cost basis, credit quality and the Companys ability and intent to hold the investment for a period of time
sufficient to allow for any anticipated recovery in market value. As discussed in Note 7, the Company recognized an impairment loss of NT$27 million for the year ended December 31, 2012 and the related impaired available-for-sale financial
assets were sold as of December 31, 2012. As a result, the Company determined that aforementioned investments with unrealized losses were not deemed to be other-than-temporarily impaired as of December 31, 2012.



| | e. | Fair value measurements
| | -- | -----------------------

The
fair value guidance requires disclosure that establishes a framework for measuring fair value and expands disclosure about fair value measurements. The standard describes a fair value hierarchy based on three levels of inputs that may be used to
measure fair value. The level in the fair value hierarchy within which the fair value measurement in its entirely falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety. These
levels are:



| | Level 1: | Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date;
| | -------- | ---------------------------------------------------------------------------------------------------------------------------------------



| | Level 2: | Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability;
or
| | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | Level 3: | Prices or valuation techniques that require inputs that are both significant to the fair value measurement and are unobservable.

Convertible bonds are actively traded or have quoted prices. For forward exchange and currency swap
contracts, fair values are estimated using industry standard valuation models. These models use market-based observable inputs including interest rate curves, foreign exchange rates, and forward and spot prices for currencies to project fair value.

Available-for-sale financial assets include open-end mutual funds, domestic and foreign listed stocks that are actively traded
or have quoted prices.

Corporate bonds are valued using market-based observable inputs including duration, yield rate and
credit rating.

The Department of Investment and the Department of Finance are responsible for the impairment tests of financial instruments. They have set forth the Companys valuation policies and procedures for
the impairment test and is responsible for reporting to General Manager regarding the changes in fair value and reasonableness of the underlying assumptions utilized in the valuation whenever the impairment test is performed.

The Company determined that intangible assets - others and other assets with carrying amounts of NT$5 million and NT$55 million will not
have future economic benefits. Therefore, the carrying amounts of both assets were written down to their fair value of nil.

The Company evaluated its cost method investees for impairment by using valuation models based on discounted future cash flows because
there were no quoted fair value for such investments. Pursuant to the established policies, the Company employed an internal valuation model in 2011 and 2012 to determine the fair value of cost method investees using the discounted cash flow
approach based on managements projections. Variables utilized in discounted cash flow approach require the use of unobservable inputs (Level 3), including return on investment, industrial risk, enterprise risk and sustainable growth rate.
Changes in management estimates to the unobservable inputs in the valuation models would significantly change the fair value of cost method investee. The return on investment is the assumption that most significantly affects the fair value
determination. Cost method investees held with a carrying amount of NT$318 million were written down to their fair value of NT$170 million, resulting in an impairment charge of NT$148 million, which was included in earnings for the year ended
December 31, 2011. Cost method investees held with a carrying amount of NT$279 million were written down to their fair value of NT$103 million, resulting in an impairment charge of NT$176 million, which was included in earnings for year ended
December 31, 2012.

Certain non-financial assets and non-financial liabilities measured at fair value on a nonrecurring
basis include other non-financial long-lived assets and idle assets measured at fair value for impairment assessment. The Company calculates these fair values using the market approach which includes recent market condition and other economic
factors as their fair value inputs. The Company used market approach which uses market multiples to evaluate the fair values of property, plant, and equipment with fair value of NT$266,869 million. The market multiples which were derived from a set
of comparables were prices and other relevant information generated by market transactions involving comparable assets and factors specific to the measurement. Multiples might lie in ranges with a different multiple for each comparable. Property,
plant, and equipment held with a carrying amount of NT$268,374 million were written down to their fair value of NT$266,869 million, resulting in an impairment charge of NT$1,505 million, which was included in earnings for the year ended
December 31, 2012. Intangible assets - others with a carrying amount of NT$5 million were written down to their fair value of nil, resulting in an impairment charge of NT$5 million, which was included in earnings for the year ended
December 31, 2012. Other assets - idle assets held with a carrying amount of NT$35 million were written down to their fair value of nil, resulting in an impairment charge of NT$35 million, which was included in earnings for the year ended
December 31, 2012. Other assets - others held with a carrying amount of NT$20 million were written down to their fair value of nil, resulting in an impairment charge of NT$20 million, which was included in earnings for the year ended
December 31, 2012.

Methods and assumptions used in the estimation of fair values of financial instruments:



| | 1) | The carrying amounts of cash and cash equivalents, other current monetary assets, refundable deposits, short-term loans, current portion of long-term loans and
customers deposits approximate fair value due to the short period of time to maturity.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2) | Other assets were Piping Fund. Based on the terms of Construction Funding Agreement, if the Piping Fund project is considered to be no longer necessary by the ROC
government, the Company will receive back its proportionate share of the net equity of the Piping Fund upon its dissolution. Therefore, the fair value was determined based on the Companys proportionate share of the net equity of the Piping
Fund as of December 31, 2012 and 2011.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3) | The Company uses discounted cash flow model with observable market data, such as Reuters Limited 60-days secondary markets bills rate based yield curve and
Chunghwa Post Co., Ltd.s one-year time deposit floating rate based yield curve, to determine the fair value of long-term bank loans. These liabilities are therefore included in Level 2.

| | g. | Income tax
| | -- | ----------

Effective from
January 1, 2007, the Company adopted the guidance of income taxes uncertainties. The guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. The guidance also provides guidance on derecognition, classification, interest and penalties, disclosure and transition. The evaluation of a tax position in accordance with the guidance is a two step process.
The first step is recognition, where we evaluate whether an individual tax position has a likelihood of greater than 50% of being sustained upon examination based on the technical merits of the position, including resolution of any related appeals
or litigation processes. For tax positions that are currently estimated to have a less than 50% likelihood of being sustained, zero tax benefit is recorded. For tax positions that have met the recognition threshold in the first step, the Company
perform the second step of measuring the benefit to be recorded. The actual benefits ultimately realized may differ from the Companys estimates. The adoption of the guidance did not have a material impact on the Company.

The Company did not identify significant unrecognized tax benefits for the years ended December 31, 2010, 2011 and 2012. The Company
did not incur any interest or penalties related to potential underpaid income tax expenses.

| | i. | Litigation
| | -- | ----------

A portion of the
land used by Chunghwa during the period July 1, 1996 to December 31, 2004 was co-owned by Chunghwa and Taiwan Post Co., Ltd. (the former Chunghwa Post Co., Ltd. directorate General of Postal Service). In accordance with the claims process
in Taiwan, on July 12, 2005, the Taiwan Taipei District Court sent a claim notice to Chunghwa to reimburse Chunghwa Post Co., Ltd. in the amount of NT$768 million for land usage compensation due to the portion of land usage area in excess of
Chunghwas ownership and along with interest calculated at 5% interest rate from June 30, 2005 to the payment date. Chunghwa stated that both parties have the right to use co-management land without consideration. Chunghwa Post Co., Ltd.
can not request payment for land compensation. Furthermore, Chunghwa believes that the computation used to derive the land usage compensation amount is inaccurate because most of the compensation amount has expired as result of the expiration
clause. Therefore, Chunghwa filed an appeal at the Taiwan Taipei District Court. On March 30, 2009, the Taiwan Taipei District Court rendered its judgment that Chunghwa only need to pay NT$17 million along with interest calculated at
5% per annum from July 23, 2005 and 4% of the court fees as the court judgment compensation. However, Chunghwa Post Co., Ltd. did not accept the judgment and filed an appeal at Taiwan High Court. Chunghwa also filed an appeal at the Taiwan
High Court within the statutory period. On April 7, 2010, the Taiwan High Court rendered its judgment, ruling that Chunghwa was required to pay NT$23 million as compensation in addition to the NT$17 million from the Taiwan Taipei District Court
judgment, along with interest calculated at 5% per annum from July 23, 2005 to the payment date and 12.5% of Chunghwa Post Co., Ltd.s court fees from its original suit and subsequent appeal as compensation. Chunghwa has filed an
appeal to the Supreme Court of the Republic of China within the statutory period. On June 22, 2011, the Supreme Court of the Republic of China remanded the aforementioned judgment from Taiwan High Court and the case was remanded back to the
Taiwan High Court. On January 6, 2012, the Taiwan High Court rendered its judgment, ruling that Chunghwa was required to pay additional land compensation NT$4 million along with related interest. Chunghwa withdrew the claim after evaluation.
