Forward-looking statements include, but are not limited to, statements regarding our strategy and future plans, future business condition and financial results, our capital expenditure plans, our capacity
management plans, expectations as to the commercial production using 20-nanometer and more advanced technologies, technological upgrades, investment in research and development, future market demand, future regulatory or other developments in our

Risk Factors

We wish to caution readers that the following important
factors, and those important factors described in other reports submitted to, or filed with, the Securities and Exchange Commission, among other factors, could affect our actual results and could cause our actual results to differ materially from
those expressed in any forward-looking statements made by us or on our behalf, and that such factors may adversely affect our business and financial status and therefore the value of your investment:

Risks Relating to Our Business

Any global systemic political, economic and financial crisis or catastrophic natural disasters (as well as the indirect effects flowing therefrom)
could negatively affect our business, results of operations, and financial condition.

In recent times, several major
systemic economic and financial crises and natural disasters negatively affected global business, banking and financial sectors, including the semiconductor industry and markets. These types of crises cause turmoil in global markets that often
result in declines in electronic products sales from which we generate our income through our goods and services. In addition, these crises may cause a number of indirect effects such as undermining the ability of our customers to remain
competitive vis-à-vis the financial and economic challenges created by insolvent countries and companies still struggling to survive in the wake of these crises. For example, there could be in the future knock-on effects from these
types of crises on our business, including significant decreases in orders from our customers; insolvency of key suppliers resulting in product delays; inability of customers to obtain credit to finance purchases of our products and/or customer
insolvencies; and counterparty failures negatively impacting our treasury operations. Even though the Tohoku earthquake and tsunami in Northeastern Japan of March 2011, and the 2011 Thailand flooding caused the global electronics supply-chain
to suffer a tighter supply in silicon wafers and electronic components, those natural disasters did not have a material impact on our past and current operations. Any future systemic political, economic or financial crisis or catastrophic
natural disaster (as well as the indirect effects flowing from these crises or disasters) could cause revenues for the semiconductor industry as a whole to decline dramatically, and if the economic conditions or financial condition of our customers
were to deteriorate, additional accounting related allowances may be required in the future and such additional allowances could increase our operating expenses and therefore reduce our operating income and net income. Thus, any future global
economic crisis or catastrophic natural disaster (and their indirect effects) could materially and adversely affect our results of operations.

Since we are dependent on the highly cyclical semiconductor and microelectronics industries, which
have experienced significant and sometimes prolonged periods of downturns and overcapacity, our revenues, earnings and margins may fluctuate significantly.

The semiconductor market and microelectronics industries have historically been cyclical and subject to significant and often rapid increases and decreases in product demand. Our semiconductor foundry
business is affected by market conditions in such highly cyclical semiconductor and microelectronics industries. Most of our customers operate in these industries. Variations in order levels from our customers result in volatility in our revenues
and earnings. From time to time, the semiconductor and microelectronics industries have experienced significant and sometimes prolonged periods of downturns and overcapacity. Any systemic economic, political, or financial crisis, such as the one
that occurred in 2008-2009, could create significant volatility and uncertainty within the semiconductor and microelectronics industries which may disrupt traditional notions of cyclicality within such industries. As such, the nature, extent and
scope of such periods of downturns and overcapacity may vary drastically in accordance with the degree of volatility of market demand. Because we are, and will continue to be, dependent on the requirements of semiconductor and microelectronics
companies for our services, periods of downturns and overcapacity in the general semiconductor and microelectronics industries lead to reduced demand for overall semiconductor foundry services, including our services. If we cannot take appropriate
actions such as reducing our costs to sufficiently offset declines in demand, our revenues, margin and earnings will suffer during periods of downturns and overcapacity. Furthermore, due to the increasingly complex technological nature of our
products and services and the ever uncertain global economic environment, we may need to provide higher accounting provisions on potential sales returns and allowances by our customers that may adversely affect the results of our operations.

Decreases in demand and average selling prices for products that contain semiconductors may adversely affect demand for our products
and may result in a decrease in our revenues and earnings.

A vast majority of our sales revenue is derived from
customers who use our services in communication devices, personal computers, consumer electronics products and other categories, such as industrial products. Any decrease in the demand for the products may decrease the demand for overall global
semiconductor foundry services, including our services and may adversely affect our revenues. Further, because we own most of our manufacturing capacities, a significant portion of our operating costs is fixed. In general, these costs do not decline
when customer demand or our capacity utilization rates drop, and thus declines in customer demand, among other factors, may significantly decrease our margins. Conversely, as product demand rises and factory utilization increases, the fixed costs
are spread over increased output, which can improve our margins. In addition, the historical and current trend of declining average selling prices (or ASP) of end use applications places downward pressure on the prices of the components
that go into such applications. If the ASP of end use applications continues decreasing, the pricing pressure on components produced by us may lead to a reduction of our revenues, margin and earnings.

If we are unable to compete effectively in the highly competitive foundry segment of the semiconductor industry, we may lose customers and our
profit margin and earnings may decrease.

The markets for our foundry services are highly competitive both in Taiwan
and internationally. We compete with other dedicated foundry service providers, as well as integrated device manufacturers. Some of these companies may have access to more advanced technologies and greater financial and other resources than us,
(such as the possibility of receiving direct or indirect government bailout/economic stimulus funds or other incentives that may be unavailable to us). Our competition may, from time to time, also decide to undertake aggressive pricing initiatives
in one or more technology nodes. Competitive activities may decrease our customer base, or our ASP, or both.

If we are unable to remain
a technological leader in the semiconductor industry, we may become less competitive.

The semiconductor industry and
its technologies are constantly changing. We compete by developing process technologies using increasingly advanced nodes and on manufacturing products with more functions. We also compete by developing new derivative technologies. If we do not
anticipate these changes in technologies and rapidly develop new and innovative technologies, or our competitors unforeseeably gain sudden access to additional technologies, we may not be able to provide foundry services on competitive terms.
Although we have concentrated on maintaining a competitive edge in research and development, if we fail to achieve advances in technologies or processes, or to obtain access to advanced technologies or processes developed by others, we may become
less competitive.

If we are unable to manage our capacity and the streamlining of our production facilities effectively,
our competitiveness may be weakened.

We perform periodic long term market demand forecasts to estimate market and
general economic conditions for our products and services. Based upon these estimates, we manage our overall capacity which may increase or decrease in accordance with market demand. Because market conditions may vary significantly and unexpectedly,
our market demand forecast may change significantly at any time. Further, since certain manufacturing lines or tools in some of our manufacturing facilities may be suspended or shut down temporarily during periods of decreased demand, we may not be
able to ramp up in a timely manner during periods of increased demand. During periods of continued decline in demand, our operating facilities may not be able to absorb and complete in a timely manner outstanding orders re-directed from shuttered
facilities. Based on demand forecasts, we have been adding capacity to our 300mm wafer fabs in the Hsinchu Science Park, Tainan Science Park and Central Taiwan Science Park, respectively. Total monthly capacity for 300mm wafer fabs was increased
from 171,400 wafers as of December 31, 2009 to 244,600 wafers as of December 31, 2010 and to 290,100 wafers as of December 31, 2011. Expansion and modification of our production facilities will, among other factors, increase our
costs. For example, we will need to purchase additional equipment, train personnel to operate the new equipment or hire additional personnel. If we do not increase our net sales accordingly, in order to offset these higher costs, our financial
performance may be adversely affected. See Item 4. Information on the Company  Capacity Management and Technology Upgrade Plans for a further discussion.

We may not be able to implement our planned growth or development if we are unable to obtain sufficient financial resources to meet our future capital requirements.

Capital requirements are difficult to plan in the highly dynamic, cyclical and rapidly changing semiconductor industry. From time to
time, we will continue to need significant capital to fund our operations and manage our capacity in accordance with market demand. Our continued ability to obtain sufficient external financing is subject to a variety of uncertainties, including:



| |  |  | our future financial condition, results of operations and cash flow;
| | - |  | --------------------------------------------------------------------



| |  |  | general market conditions for financing activities;
| | - |  | ---------------------------------------------------



| |  |  | market conditions for financing activities of semiconductor companies; and
| | - |  | --------------------------------------------------------------------------



| |  |  | social, economic, financial, political and other conditions in Taiwan and elsewhere.
| | - |  | ------------------------------------------------------------------------------------

Sufficient external financing may not be available to us on a timely basis, on reasonable market terms, or at all. As a result, we may be
forced to curtail our expansion and modification plans or delay the deployment of new or expanded services until we obtain such financing.

We may not be able to implement our planned growth and development or maintain our leading position if we are unable to recruit and retain
qualified executives, managers and skilled technical and service personnel or suffer production disruptions caused by labor disputes.

We depend on the continued services and contributions of our executive officers and skilled technical and other personnel. Our business could suffer if we lose, for whatever reasons, the services and
contributions of some of these personnel and we cannot adequately replace them, or if we suffer disruptions to our production operations arising from labor or industrial disputes. We may be required to increase or reduce the number of employees in
connection with any business expansion or contraction, in accordance with market demand for our products and services. Since there is intense competition for the recruitment of these personnel, we cannot ensure that we will be able to fulfill our
personnel requirements, or rehire such reduced personnel on comparable terms in a timely manner during an economic upturn.

##### Table of Contents

We may be unable to obtain in a timely manner and at a reasonable cost the equipment necessary for us
to remain competitive.

Our operations and ongoing expansion plans depend on our ability to obtain an appropriate
amount of equipment and related services from a limited number of suppliers in a market that is characterized by limited supply and long delivery cycles. During such times, supplier-specific or industry-wide lead times for delivery can be as long as
six months or more. To better manage our supply chain, we have implemented various business models and risk management contingencies with suppliers to shorten the procurement lead time. We also provide our projected demand for various items to many
of our equipment suppliers to help them plan their production in advance. We have purchased used tools and continue to seek opportunities in acquiring relevant used tools. If we are unable to obtain equipment in a timely manner to fulfill our
customers orders, or at a reasonable cost, our financial condition and results of operations could be negatively impacted.

Our
revenue and profitability may decline if we are unable to obtain adequate supplies of raw materials in a timely manner and at reasonable prices.

Our production operations require that we obtain adequate supplies of raw materials, such as silicon wafers, gases, chemicals, and photoresist, on a timely basis. Shortages in the supply of some materials
experienced by specific vendors or by the semiconductor industry generally have in the past resulted in occasional industry-wide price adjustments and delivery delays. Also, since we procure some of our raw materials from sole-source suppliers,
there is a risk that our need for such raw materials may not be met when needed or that back-up supplies may not be readily available. Our revenue and earnings could decline if we are unable to obtain adequate supplies of the necessary raw materials
in a timely manner or if there are significant increases in the costs of raw materials that we cannot pass on to our customers.

If the
Ministry of Economic Affairs uses a substantial portion of our production capacity, we will not be able to service our other customers.

According to our agreement with the Industrial Technology Research Institute of Taiwan, or ITRI, the Ministry of Economic Affairs of the R.O.C., or an entity designated by the Ministry of Economic
Affairs, has an option to purchase up to 35% of certain of our capacity, if our outstanding commitments to our customers are not prejudiced. Although the Ministry of Economic Affairs has never exercised this option, if this option is exercised to
any significant degree during tight market conditions, we may not be able to provide services to all of our other customers unless we are able to increase our capacity accordingly or outsource such increased demand and in a timely manner.

Any inability to obtain, preserve and defend our technologies and intellectual property rights could harm our competitive position.

Our ability to compete successfully and to achieve future growth will depend in part on the continued strength of our
intellectual property portfolio. While we actively enforce and protect our intellectual property rights, there can be no assurance that our efforts will be adequate to prevent the misappropriation or improper use of our proprietary technologies,
trade secrets, software or know-how. Also, we cannot assure you that, as our business or business models expand into new areas, or otherwise, we will be able to develop independently the technologies, trade secrets, patents, software or know-how
necessary to conduct our business or that we can do so without unknowingly infringing the intellectual property rights of others. As a result, we may have to rely increasingly on licensed technologies and patent licenses from others. To the extent
that we rely on licenses from others, there can be no assurance that we will be able to obtain any or all of the necessary licenses in the future on terms we consider reasonable or at all. The lack of necessary licenses could expose us to claims for
damages and/or injunctions from third parties, as well as claims for indemnification by our customers in instances where we have contractually agreed to indemnify our customers against damages resulting from infringement claims.

We have received, from time-to-time, communications from third parties asserting that our technologies, manufacturing processes, the
design of the integrated circuits made by us or the use by our customers of semiconductors made by us may infringe their patents or other intellectual property rights. And, because of the nature of the industry, we may continue to receive such
communications in the future. In some instances, these disputes have resulted in litigation. Recently, there has been a notable increase in the number of claims or lawsuits initiated by certain litigious, non-practicing entities and these
non-practicing entities are also becoming more aggressive in their monetary demands and requests for court-issued injunctions. Such lawsuits or claims may increase our cost of doing business and may potentially be extremely disruptive if the
plaintiffs succeed in blocking the trade of our products and services. If we fail to obtain or maintain certain government, technologies or intellectual property licenses and, if litigation relating to alleged intellectual property matters occurs,
it could prevent us from manufacturing or selling particular products or applying particular technologies, which could reduce our opportunities to generate revenues. See Item 8. Financial Information  Legal Proceedings for a
further discussion.

We are subject to the risk of loss due to explosion and fire because some of the materials we use in
our manufacturing processes are highly combustible.

We and many of our suppliers use highly combustible and toxic
materials in our manufacturing processes and are therefore subject to the risk of loss arising from explosion, fire, or environmental influences which cannot be completely eliminated. Although we maintain many overlapping risk prevention and
protection systems, as well as comprehensive fire and casualty insurance, including insurance for loss of property and loss of profit resulting from business interruption, our risk management and insurance coverage may not be sufficient to cover all
of our potential losses. If any of our fabs or vendor facilities were to be damaged, or cease operations as a result of an explosion, fire, or environmental influences, it could reduce our manufacturing capacity and may cause us to lose important
customers, thereby having a potentially adverse and material impact on our financial performance.

Any impairment charges may have a
material adverse effect on our net income.

Under R.O.C. GAAP and U.S. GAAP, we are required to evaluate our
long-lived assets and intangible assets for impairment whenever triggering events or changes in circumstances indicate that the asset may be impaired and carrying value may not be recoverable. If certain criteria are met, we are required to record
an impairment charge. We are also required under R.O.C. GAAP and U.S. GAAP to evaluate goodwill for impairment at least on an annual basis or more frequently whenever triggering events or changes in circumstances indicate that goodwill may be
impaired and the carrying value may not be recoverable.

We currently are not able to estimate the extent or timing of any
impairment charge for future years. Any impairment charge required may have a material adverse effect on our net income.

The
determination of an impairment charge at any given time is based significantly on our expected results of operations over a number of years subsequent to that time. As a result, an impairment charge is more likely to occur during a period when our
operating results are otherwise already depressed. See Item 5. Operating and Financial Review and Prospects  Critical Accounting Policies for a discussion of how we assess if an impairment charge is required and, if so, how the
amount is determined.

The loss of or significant curtailment of purchases by any of our largest customers could adversely affect our
results of operations.

While we generate revenue from hundreds of customers worldwide, our ten largest customers
accounted for approximately 53%, 54% and 56% of our net sales in 2009, 2010 and 2011, respectively. Our largest customer accounted for 10%, 9% and 14% of our net sales in 2009, 2010 and 2011, respectively. The loss of, or significant curtailment of
purchases by, one or more of our top customers, including curtailments due to increased competitive pressures, industrial consolidation, a change in their designs, or change in their manufacturing sourcing policies or practices of these customers,
or the timing of customer or distributor inventory adjustments, may adversely affect our results of operations and financial condition.

Any failure to achieve and maintain effective internal controls could have a material adverse effect on our business and results of operations.

Effective internal controls are necessary for us to provide reasonable assurance with respect to our financial
reports and to effectively prevent fraud. If we cannot provide reasonable assurance with respect to our financial reports and effectively prevent fraud and corruption, our reputation and results of operations could be harmed.

We are required to comply with various R.O.C. and U.S. laws and regulations on internal controls. For example, pursuant to
Section 404 of the Sarbanes-Oxley Act of 2002, beginning with the Annual Report on Form 20-F for the fiscal year ended December 31, 2006, we are required to furnish a report by management on our internal control over financial reporting,
including managements assessment of the effectiveness of our internal control over financial reporting. Moreover, R.O.C. law requires us to establish internal control systems that would reasonably ensure the effectiveness and efficiency of
operations, reliability of financial reporting, and compliance with applicable laws and regulations. We are also required under R.O.C. law to file an internal control declaration within four months of the end of each fiscal year.

Internal controls may not prevent or detect misstatements because of their inherent
limitations, including the possibility of human error, the circumvention or overriding of controls, fraud or corruption. Therefore, even effective internal controls can provide only reasonable assurance with respect to the preparation and fair
presentation of financial statements. In addition, projections of any evaluation of effectiveness of internal controls to future periods are subject to the risk that the internal controls may become inadequate because of changes in conditions, or
that the degree of compliance with the policies or procedures may deteriorate. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in
their implementation, our business and operating results could be harmed, we could fail to meet our reporting obligations, and there could be a material adverse effect on the market price of our common shares and ADSs.

Our global manufacturing, design and sales activities subject us to risks associated with legal, political, economic or other conditions or
developments in various jurisdictions, including in particular the R.O.C., which could negatively affect our business and financial status and therefore the market value of your investment.

Our principal executive officers and our principal production facilities are located in the R.O.C., and a substantial majority of our net
revenues are derived from our operations in the R.O.C. In addition, we have operations worldwide and a significant percentage of our revenue comes from sales to locations outside the R.O.C. Operating in the R.O.C. and overseas exposes us to changes
in policies and laws, as well as the general political and economic conditions, security risks, health conditions and possible disruptions in transportation networks, in the various countries in which we operate, which could result in an adverse
effect on our business operations in such countries and our results of operations as well as the market price and the liquidity of our ADSs and common shares.

For example, even though the R.O.C. and the PRC have co-existed for the past 62 years and significant economic and cultural relations have been established during that time, the financial markets have
viewed certain past developments in relations between the two sides as occasions to depress general market prices of the securities of Taiwanese companies, including our own. In addition, the R.O.C. government has not lifted some trade and
investment restrictions imposed on Taiwanese companies on the amount and types of certain investments that can be made in Mainland China.

Our operational results could also be materially and adversely affected by natural disasters or interruptions in the supply of utilities (such as
water or electricity), in the locations in which we, our customers or our suppliers operate.

The apparent frequency
and severity of natural disasters has increased recently. We have manufacturing and other operations in locations subject to natural disasters, such as severe weather, flooding, earthquakes and tsunamis, as well as interruptions or shortages in the
supply of utilities, such as water and electricity, which could disrupt operations. We have operations in earthquake-prone locations and any major natural disaster occurring in any such locations may cause severe disruptions to our business
operations and financial performance. In addition, our suppliers and customers also have operations in such locations. For example, most of our production facilities, as well as those of many of our suppliers and customers and upstream providers of
complementary semiconductor manufacturing services, are located in Taiwan and Japan, which are susceptible to earthquakes, tsunamis, flooding, typhoons, and droughts from time to time. In addition, we have sometimes suffered power outages in Taiwan
caused by difficulties encountered by our electricity supplier, the Taiwan Power Company, or other power consumers on the same power grid, which have resulted in interruptions to our production schedule. While our business continuity management and
emergency response plans are intended to prevent or minimize losses in the future, there is no assurance that the measures will fully eliminate the losses or the insurance will fully cover any losses. One or more natural disasters or interruptions
to the supply of utilities that results in a prolonged disruption to our operations, or the operations of our customers or suppliers, may adversely affect the results of our operations and financial conditions.

Our failure to comply with applicable environmental and climate related laws and regulations, as well
as international accords to which we are subject, could also harm our business and operational results.

The
manufacturing, assembling and testing of our products require the use of chemicals and materials that are subject to environmental, climate-related, and health and safety laws and regulations issued worldwide. Although we may be eligible for various
exemptions and/or extensions of time for compliance, our failure to comply with any of these applicable laws or regulations could result in:



| |  |  | significant penalties and legal liabilities, such as the denial of import permits;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | the temporary or permanent suspension of production of the affected products;
| | - |  | -----------------------------------------------------------------------------



| |  |  | unfavorable alterations in our manufacturing, fabrication and assembly and test processes; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | restrictions on our operations or sales.
| | - |  | ----------------------------------------

Existing and future environmental and climate related laws and regulations as well as applicable international accords to which we are subject, could also require us, among other things, to do the
following: (a) purchase, use or install expensive pollution control, reduction or remediation equipment; (b) implement climate change mitigation programs and abatement or reduction of greenhouse gas emissions programs, or
carbon credit trading programs; (c) modify our product designs and manufacturing processes, or incur other significant expenses associated with such laws and regulations such as obtaining substitute raw materials or chemicals that
may cost more or be less available for our operations. It is still unclear whether such necessary actions would affect the reliability or efficiency of our products and services.

Any of the above contingencies resulting from the actual and potential impact of local or international laws and regulations, as well as
international accords on environmental or climate change, could harm our business and operational results by increasing our expenses or requiring us to alter our manufacturing and assembly and test processes. For further details, please see our
compliance record with Taiwan and international environmental and climate related laws and regulations in Item 4. Information on the Company  Environmental Regulations.

Climate change, other environmental concerns and green initiatives also present other commercial challenges, economic risks and physical risks that could harm our operational results or affect the
manner in which we conduct our business.

Increasing climate change and environmental concerns could affect the
results of our operations if any of our customers request that we exceed any standard(s) set for environmentally compliant products and services. For example, we have been working with our suppliers, customers, and several industry consortia to
develop and provide products that are compliant with the EU RoHS (European Union Restriction of Hazardous Substances) Directive. Even though we are entitled to rely on various exemptions under RoHS, some of our customers might request
that we provide products that exceed the legal standard set by RoHS without using any of the exemptions still permitted under RoHS. If we are unable to offer such products or offer products that are compliant, but are not as reliable due to the lack
of reasonably available alternative technologies or materials, we may lose market share to our competitors.

Further, energy
costs in general could increase significantly due to climate change and other regulations. Therefore, our energy costs may increase significantly if utility or power companies pass on their costs, either fully or partially, such as those associated
with carbon taxes, emission cap and carbon credit trading programs. For further details, please see details of our business continuity management of climate change policy in Item 4. Information on the Company  Environmental
Regulation.

In order to mitigate risks resulting from climate change, we continue to actively carry out energy
conservation measures, implement voluntary perfluorinated compounds (PFCs) emission reduction projects and conduct greenhouse gas inventories and verification every year. Since 2005, we have publicly disclosed climate change information
every year through participation in the annual survey conducted by the nonprofit carbon disclosure project, which includes greenhouse gas emission and reduction information for all of our fabs.

Adverse fluctuations in exchange rates could decrease our operating margin.

Over one-half of our capital expenditures and manufacturing costs are denominated in currencies other than NT dollars, primarily in U.S. dollars,
Japanese yen and Euros. More than 90% of our sales are denominated in U.S. dollars and currencies other than NT dollars. Therefore, any significant fluctuation to our disadvantage in such exchange rates would have an adverse effect on our financial
condition. For example, during the period from September 1, 2010 to December 30, 2010, the U.S. dollar depreciated 8.9% against the NT dollar, which had a negative impact on our results of operations. Specifically, every 1% depreciation of
the U.S. dollar against the NT dollar exchange rate results in approximately 0.4 percentage point decrease in our operating margin. In addition, fluctuations in the exchange rate between the U.S. dollar and the NT dollar may affect the U.S. dollar
value of our common shares and the market price of the ADSs and of any cash dividends paid in NT dollars on our common shares represented by ADSs. Please see Item 11. Quantitative and Qualitative Disclosures About Market Risk for a
further discussion on the possible impact of other market factors on our results of operations.

Fluctuations in inflationary and
deflationary market expectations could negatively affect costs of and demand for our products and services, which may harm our financial results.

The world economy is becoming more vulnerable to sudden unexpected fluctuations in inflationary and deflationary market expectations and conditions. For example, certain structural changes that resulted
from the 2008-2009 and recent EU financial crises may cause variations in the expectation of inflation or deflation. Both high inflation and deflation adversely affect an economy, at both the macro and micro levels, by reducing economic efficiency,
disrupting saving and investment decisions and reducing the efficiency of the market prices as a mechanism to allocate resources. Such fluctuations are likely to negatively affect the costs of our operations and the business operations of our
customers who may be forced to plan their purchases of our goods and services within an uncertain macro and micro economy. Therefore, the demand for our products and services could unexpectedly fluctuate severely in accordance with market and
consumer expectations of inflation or deflation. Please see Item 5. Operating and Financial Review and Prospects  Inflation & Deflation for a further discussion.

Risks Relating to Ownership of ADSs

Your voting rights as a holder of ADSs will be
limited.

Holders of American Depositary Receipts (ADRs) evidencing ADSs may exercise voting rights with respect to
the common shares represented by these ADSs only in accordance with the provisions of our ADS 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, mail to the holders (i) the notice of the meeting sent by us, (ii) voting instruction forms and (iii) a statement as to the manner in which instructions may be given by the holders.

ADS holders will not generally be able to exercise the voting rights attaching to the deposited securities on an individual basis.
According to the provisions of our ADS deposit agreement, the voting rights attaching to the deposited securities must be exercised as to all matters subject to a vote of shareholders collectively in the same manner, except in the case of an
election of directors. Election of directors is by means of cumulative voting. See Item 10. Additional Information  Voting of Deposited Securities for a more detailed discussion of the manner in which a holder of ADSs can exercise
its voting rights.

You may not be able to participate in rights offerings and may experience dilution of your holdings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under our
ADS deposit agreement, the depositary bank will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the United States
Securities Act of 1933, as amended, (the Securities Act), with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. Although we may be eligible to take advantage of certain exemptions for rights
offerings by certain foreign companies, we can give no assurance that we can establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to any such rights or
underlying securities or to endeavor to have such a registration statement declared effective. In addition, if the depositary bank is unable to obtain the requisite approval from the Central Bank of the Republic of China (Taiwan) for the conversion
of the subscription payments into NT dollars or if the depositary determines that it is unlikely to obtain this approval, we may decide with the depositary bank not to make the rights available to holders of ADSs. See Item 10. Additional
Information  Foreign Investment in the R.O.C. and Item 10. Additional Information  Exchange Controls in the R.O.C.. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience
dilution of their holdings as a result.

##### Table of Contents

If the depositary bank 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.

The value of your investment may be reduced by possible future sales of common shares or ADSs by us or our shareholders.

One or more of our existing shareholders may, from time to time, dispose of significant numbers of our common shares or ADSs. For
example, the National Development Fund of Taiwan, R.O.C. which owned 6.4% of TSMCs outstanding shares as of February 29, 2012, has sold our shares in the form of ADSs in several transactions during the period between 1997 and 2005.

We cannot predict the effect, if any, that future sales of ADSs or common shares, or the availability of ADSs or common
shares for future sale, will have on the market price of ADSs or common shares prevailing from time to time. Sales of substantial amounts of ADSs or common shares in the public market, or the perception that such sales may occur, could depress the
prevailing market price of our ADSs or common shares.

The market value of our shares may fluctuate due to the volatility of, and
government intervention in, the R.O.C. securities market.

Because the Taiwan Stock Exchange experiences from time to
time substantial fluctuations in the prices and volumes of sales of listed securities, there are currently limits on the range of daily price movements on the Taiwan Stock Exchange. In response to past declines and volatility in the securities
markets in Taiwan, and in line with similar activities by other countries in Asia, the government of the R.O.C. formed the Stabilization Fund, which has purchased and may from time to time purchase shares of Taiwan companies to support these
markets. In addition, other funds associated with the R.O.C. government have in the past purchased, and may from time to time purchase, shares of Taiwan companies on the Taiwan Stock Exchange or other markets. In the future, market activity by
government entities, or the perception that such activity is taking place, may take place or has ceased, may cause fluctuations in the market prices of our ADSs and common shares.

We believe that our large capacity, particularly for advanced technologies, is a major
competitive advantage. Please see  Manufacturing Capacity and Technology and  Capacity Management and Technology Upgrade Plans for a further discussion of our capacity.

We count among our customers many of the worlds leading semiconductor companies, ranging from fabless semiconductor and system
companies such as Advanced Micro Devices, Inc., Altera Corporation, Broadcom Corporation, Marvell Semiconductor Inc., MediaTek Inc., nVidia Corporation and Qualcomm Incorporated, to integrated device manufacturers such as LSI Corporation,
STMicroelectronics and Texas Instruments Inc. Fabless semiconductor and system companies accounted for approximately 81%, and integrated device manufacturers accounted for approximately 19% of our net sales in 2011.

Our Semiconductor Facilities

We currently operate one 150mm wafer fab, six 200mm wafer fabs and three 300mm wafer fabs, including Fab 15, where we commenced production in the first quarter of 2012. Our corporate headquarters and five
of our fabs are located in the Hsinchu Science Park, two fabs are located in the Tainan Science Park, one fab is located in the Central Taiwan Science Park, one fab is located in the United States, and one fab is located in Shanghai. Our corporate
headquarters and our five fabs in Hsinchu occupy parcels of land of a total of approximately 555,300 square meters. We lease these parcels from the Hsinchu Science Park Administration in Hsinchu under agreements that will be up for renewal between
May 2013 and December 2029. We have leased from the Central Taiwan Science Park Administration a parcel of land of approximately 184,400 square meters for our Taichung fabs under agreements that will be up for renewal in December 2028. We have
leased from the Southern Taiwan Science Park Development Office approximately 612,700 square meters of land for our fabs in the Tainan Science Park under agreements that will be up for renewal between July 2017 and January 2032. WaferTech owns a
parcel of land of approximately 1,052,186 square meters in the State of Washington in the United States, where the WaferTech fab and related offices are located. TSMC China owns the land use rights of 369,100 square meters of land in Shanghai, where
Fab 10 and related offices are located. Other than certain equipment under leases located at testing areas, we own all of the buildings and equipment for our fabs. We are expanding our 300mm fabrication capacity and research and development through
Fab 12 in the Hsinchu Science Park, Fab 14 in the Tainan Science Park and Fab 15 in the Central Taiwan Science Park. Total monthly capacity for 300mm wafer fabs was increased from 171,400 wafers as of December 31, 2009 to 244,600 wafers as of
December 31, 2010 and to 290,100 wafers as of December 31, 2011. We will continuously evaluate our capacity in light of prevailing market conditions.

Semiconductor Manufacturing Capacity and Technology

We manufacture
semiconductors on silicon wafers based on proprietary circuitry designs provided by our customers or third party designers. Two key factors that characterize a foundrys manufacturing capabilities are output capacity and fabrication process
technologies. Since our establishment, we have possessed the largest capacity among the worlds dedicated foundries. We also believe that we are the technology leader among the dedicated foundries in terms of our net sales of advanced
semiconductors with a resolution of 65-nanometer and below, and are one of the leaders in the semiconductor manufacturing industry generally. We are the first semiconductor foundry with proven low-k interconnect technology in commercial production
from the 0.13 micron node down to 28-nanometer node. Following our commercial production based on 65-nanometer Nexsys® process technology in 2006, we also unveiled 55-nanometer Nexsys® process technology in 2007. Our 65-nanometer and
55-nanometer Nexsys® technologies are the third-generation proprietary processes that employ low-k dielectrics. In 2008, we also qualified our 45-nanometer and 40-nanometer process technologies with ultra low-k dielectrics and advanced immersion
lithography. In the fourth quarter of 2011, we have begun volume production of 28-nanometer products with first-generation high-k/metal gate transistor.

and will not increase or decrease the stipulated quantity by more than 5,000 wafers per month. Please see Item 7. Major Shareholders and Related Party Transactions  Related Party Transactions  Vanguard International Semiconductor
Corporation for a discussion of certain of the Vanguard contract terms. The amounts to be used at Vanguard are not included in our monthly capacity figures.

As of December 31, 2011, our monthly capacity (in 200mm equivalent wafers) was 1,163,708 wafers, compared to 1,036,871 wafers at the end of 2010. This increase was primarily due to the expansion of
our 28/40/65-nanometer advanced technologies. Our semiconductor manufacturing facilities require substantial investment to construct and are largely fixed-cost assets once they are in operation. Because we own most of our manufacturing capacity, a
significant portion of our operating costs is fixed. In general, these costs do not decline when customer demand or our capacity utilization rates drop, and thus declines in customer demand, among other factors, may significantly decrease our
margins. Conversely, as product demand rises and factory utilization increases, the fixed costs are spread over increased output, which can improve our margins.

Capacity Management and Technology Upgrade Plans

We periodically perform
long term market demand forecasts to estimate market and general economic conditions for our products and services. Based upon these estimates, we manage our overall capacity which may increase or decrease in accordance with market demand. Because
market conditions may vary significantly and unexpectedly, our market demand forecast may change significantly at any time. Based on current demand forecasts, we intend to maintain our strategy of expanding manufacturing capacity and improving
manufacturing process technologies to meet both the fabrication and the technological needs of our customers.

Our capital
expenditures in 2009, 2010 and 2011 were NT$87,785 million, NT$186,944 million and NT$213,963 million (US$7,286 million, translated from a weighted average exchange rate of NT$29.367 to US$1.00), respectively. Our capital expenditures in 2012 are
expected to be approximately US$6 billion, which, depending on market conditions, may be adjusted upwards later. For the past few years, our capital expenditures were funded by our operating cash flow. The capital expenditures for 2012 are also
expected to be funded by our operating cash flow. In 2012, we anticipate our capital expenditures to focus primarily on the following:

We categorize our net sales based on the country in which the customer is headquartered, which may be
different from the net sales for the countries to which we actually sell or ship our products. Under this approach, the following table presents a regional geographic breakdown of our net sales during the last three years:

A significant portion of our net sales are attributable to a relatively small number of customers. In
2009, 2010 and 2011, our ten largest customers accounted for approximately 53%, 54% and 56% of our net sales, respectively. Our largest customer accounted for 10%, 9% and 14% of our net sales in 2009, 2010 and 2011, respectively.

Over the years, we have attempted to strategically manage our exposure to commodity memory semiconductor manufacturing services. This
policy has successfully shielded us from significant adverse effects resulting from the previous precipitous price drops in the commodity memory semiconductor market.

We provide worldwide customer support. Our office in Hsinchu and wholly-owned subsidiaries in the United States, Japan, Mainland China, the Netherlands, South Korea and India are dedicated to serving our
customers worldwide. Foundry services, which are both technologically and logistically intensive, involve frequent and in-depth interaction with customers. We believe that the most effective means of providing foundry services is by developing
direct and close relationships with our customers. Our customer service and technical support managers work closely with the sales force to offer integrated services to customers. To facilitate customer interaction and information access on a
real-time basis, a suite of web-based applications have also been offered to provide more active interactions with customers in design, engineering and logistics, collectively branded as eFoundry® service.

Commitments by Customers. Because of the fast-changing technology and
functionality in semiconductor design, foundry customers generally do not place purchase orders far in advance to manufacture a particular type of product. However, we engage in discussions with customers regarding their expected manufacturing
requirements in advance of the placement of purchase orders.

Several of our customers have entered into arrangements with us
to ensure that they have access to specified capacity at our fabs. These arrangements are primarily in the form of deposit agreements. In a deposit agreement, the customer makes an advance cash deposit for an option on a specified capacity at our
fabs. Deposits are generally refunded as shipments are made. As of December 31, 2011, our customers had on deposit an aggregate of approximately US$13 million to reserve future capacity.

The Semiconductor Fabrication Process

In general, the semiconductor
manufacturing process begins with a thin silicon wafer on which an array of semiconductor devices is fabricated. The wafer is then tested, cut into dice, and assembled into packages that are then individually retested. Our focus is on wafer
fabrication although we also provide all other services either directly or through outsourcing arrangements.

Our Foundry Services

Range of Services. Because of our ability to provide a full array of services, we are able to accommodate
customers with a variety of needs at every stage of the overall foundry process. The flexibility in input stages allows us to cater to a variety of customers with different in-house capabilities and thus to service a wider class of customers as
compared to a foundry that cannot offer design or mask making services, for example.

Fabrication Processes. We
manufacture semiconductors using the complementary metal oxide silicon, CMOS and BiCMOS processes. The CMOS process is currently the dominant semiconductor manufacturing process. The BiCMOS process combines the high speed of the bipolar circuitry
and the low power consumption and high density of the CMOS circuitry. We use the CMOS process to manufacture logic semiconductors, memory semiconductors including static random access memory (SRAM), flash memory, mixed-signal/radio
frequency (RF) semiconductors, which combine analog and digital circuitry in a single semiconductor, micro-electro-mechanical-system (MEMS), which combines micrometer featured mechanical parts, analog and digital circuitry in
a single semiconductor, and embedded memory semiconductors, which combine logic and memory in a single semiconductor. The BiCMOS process is used to make high-end mixed-signal and other types of semiconductors.

Types of Semiconductors We Manufacture. We manufacture different types of semiconductors with different specific functions
by changing the number and the combinations of conducting, insulating and semiconducting layers and by defining different patterns in which such layers are applied on the wafer. At any given point in time, there are hundreds of different products in
various stages of fabrication at our fabs. We believe that the keys to maintaining high production quality and utilization rates are our effective management and control of the manufacturing process technologies which comes from our extensive
experience as the longest existing dedicated foundry and our dedication to quality control and process improvements.

The
following is a general, non-exhaustive description of the key types of semiconductors that we currently manufacture. Depending on future market conditions, we may provide other services or manufacture other types of products that may differ
significantly from the following:

Logic Semiconductors. Logic semiconductors process digital data to control
the operation of electronic systems. The largest segment of the logic market, standard logic devices, includes microprocessors, microcontrollers, digital signal processors (DSP), graphic chips and chip sets.

Mixed-Signal/RF Semiconductors. Analog/digital semiconductors combine analog and digital devices on a single semiconductor
to process both analog and digital data. We make mixed-signal/RF semiconductors using both the CMOS and BiCMOS processes. We currently offer CMOS mixed-signal process down to the 28-nanometer Nexsys® technology for manufacturing mixed-signal/RF
semiconductors. The primary uses of mixed-signal/RF semiconductors are in hard disk drives, wireless communications equipment and network communications equipment, with those made with the BiCMOS process occupying the higher end of the
mixed-signal/RF market.

##### Table of Contents

Memory Semiconductors. Memory semiconductors, which are used in electronic
systems to store data and program instructions, are generally classified as either volatile memories (which lose their data content when power supplies are switched off) or nonvolatile memories (which retain their data content without the need for a
constant power supply). We currently offer CMOS process for the manufacture of SRAM, embedded DRAM as volatile memories, and for the manufacture of flash memory and embedded flash as nonvolatile memories.

CMOS Image Sensor Semiconductors. Image sensors are primarily used in camera phones and tablets. We are currently the
leading foundry for the production of CMOS image sensors, characterized by technology features including low dark current, high sensitivity, small pixel size and high dynamic range achieved through integration with mixed mode processes.

High Voltage Semiconductors. We currently offer a range of high-voltage processes including high voltage CMOS
(HVCMOS), bipolar-CMOS-DMOS (BCD) and ultra-high voltage technology (UHV), ranging from 5V to 700V, which are suitable for various panel-size display driver and power IC applications.

Design and Technology Platforms. Modern IC designers need sophisticated design infrastructure to optimize productivity and
cycle time. Such infrastructures include design flow for electronic design automation (EDA), silicon proven building blocks such as libraries and IPs, simulation and verification design kits such as process design kit (PDK) and tech files. All of
these infrastructures are built on top of the technology foundation, and each technology needs its own design infrastructure to be usable for designers. This is the concept of our technology platforms.

For years, TSMC and its alliance partners spent considerable effort, time and resources to build our technology platforms. We unveiled
our Open Innovation Platform® (OIP) initiative in 2008 to further enhance our technologies offerings. More OIP deliverables were introduced in 2011. In the design methodology area, in addition to the introduction of the 12th release
of Reference Flow, we also announced the second release of Analog/Mixed Signal (AMS) Reference Flow, and the third release of the Radio Frequency Reference Design Kit (RF RDK).

Multi-project Wafers Program (CyberShuttle). To help our customers reduce costs, we offer a dedicated
multi-project wafer processing service that allows us to provide multiple customers with circuits produced with the same mask. This program reduces mask costs by a very significant amount, resulting in accelerated time-to-market for our customers.
We have extended this program to all of our customers and library and IP partners using our broad selection of process technologies, ranging from the latest 20-, 28-, 40-, 45-, 55- and 65-nanometer processes to 0.18-, 0.25- and 0.35-micron. This
extension offers a routinely scheduled multi-project wafer run to customers on a shared-cost basis for prototyping and verification.

##### Table of Contents

We developed our multi-project wafer program in response to the current system-on-chip
development methodologies, which often require the independent development, prototyping and validation of several IPs before they can be integrated onto a single device. By sharing mask costs among our customers to the extent permissible, the
system-on-chip supplier can enjoy reduced prototyping costs and greater confidence that the design will be successful.

Customer Service

We believe that our devotion to customer service has been an indispensable factor in attracting new customers, helping to
ensure the satisfaction of existing customers, and building a mutually beneficial relationship with our customers. The key elements are our:



| |  |  | customer-oriented culture through multi-level interaction with customers;
| | - |  | -------------------------------------------------------------------------



| |  |  | ability to deliver wafers of consistent quality, competitive ramp-up speed and fast yield improvement;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | responsiveness to customers issues and requirements, such as engineering change orders and special wafer handling;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | flexibility in manufacturing processes, supported by our competitive technical capability and production planning;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | dedication to help reduce customer costs through collaboration and services, such as our multi-project wafer program, which combines multiple designs
on a single mask set for cost-saving; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | availability of eFoundry®, the online service which provides real-time necessary information in design, engineering, and logistics to ensure
seamless services to our customers throughout product life cycle.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We also conduct an annual customer
satisfaction survey to assess customer satisfaction and to ensure that their needs and wants are adequately understood and addressed. Continual improvement plans based upon customer feedback are an integral part of this business process. We use data
derived from the survey as a key indicator of our corporate performance as well as a leading indicator of future performance. We believe that satisfaction leads to better customer relationships, which would result in more business opportunities.

Research and Development

The semiconductor industry is characterized by rapid changes in technology, frequently resulting in the introduction of new technologies to meet customers demands and in the obsolescence of recently
introduced technology and products. We believe that, in order to stay technologically ahead of our competitors and to maintain our market position in the foundry segment of the semiconductor industry, we need to maintain our position as a technology
leader not only in the foundry segment but in the semiconductor industry in general. We spent NT$21,593 million, NT$29,707 million and NT$33,830 million (US$1,118 million) in 2009, 2010 and 2011, respectively, on research and development, which
represented 7.3%, 7.1% and 7.9% of our net sales for these periods. We plan to continue to invest significant amounts on research and development in 2012, with the goal of maintaining a leading position in the development of advanced process
technologies. Our research and development efforts have allowed us to provide our customers access to certain advanced process technologies, such as 65-nanometer, 55-nanometer, 45-nanometer, 40-nanometer and 28-nanometer Nexsys® technology for
volume production, prior to the implementation of those advanced process technologies by many integrated device manufacturers and our competitors. In addition, we expect to advance our process technologies further down to 20/14-nanometer and below
in the coming years to maintain our technology leadership. We will also continue to invest in research and development for our mainstream technologies offerings to provide function-rich process capabilities to our customers. Our research and
development efforts are divided into centralized research and development activities and research and development activities undertaken by each of our fabs. Our centralized research and development activities are principally directed toward
developing new Logic, system-on-chip (SOC), derivatives and package/system-in-package (SIP) technologies, and cost-effective 3D IC Chip on Wafer on Substrate (CoWoS) solutions. Fab-related research and development
activities mostly focus on upgrading the manufacturing process technologies.

##### Table of Contents

In continuing to advance our process technologies, we intend to rely primarily on our
internal engineering capability and know-how and our research and development efforts, including collaboration with our customers, equipment vendors and R&D consortia.

We also continuously create in-house inventions and know-how. Since our inception, every year we apply for and are issued a substantial number of United States and other patents, the majority of which are
semiconductor-related.

Equipment

The quality and technology of the equipment used in the semiconductor manufacturing process are important in that they effectively define the limits of our process technologies. Advances in process
technologies cannot be brought about without commensurate advances in equipment technology. The principal pieces of equipment used by us to manufacture semiconductors are scanners, cleaners and track equipment, inspection equipment, etchers,
furnaces, wet stations, strippers, implanters, sputterers, CVD equipment, testers and probers. Other than certain equipment under leases located at testing areas, we own all of the equipment used at our fabs.

In implementing our capacity management and technology advancement plans, we expect to make significant purchases of equipment required
for semiconductor manufacturing. Some of the equipment is available from a limited number of vendors and/or is manufactured in relatively limited quantities, and certain equipment has only recently been developed. We believe that our relationships
with our equipment suppliers are good and that we have enjoyed the advantages of being a major purchaser of semiconductor fabrication equipment. We work closely with manufacturers to provide equipment customized to our needs for certain advanced
technologies.

Raw Materials

Our manufacturing processes use many raw materials, primarily silicon wafers, chemicals, gases and various types of precious metals. Raw materials costs constituted 13.0% of our net sales in 2010 and
12.6% of our net sales in 2011. Although most of our raw materials are available from multiple suppliers, some materials are purchased through sole-sourced vendors. Our raw material procurement policy is to select only those vendors who have
demonstrated quality control and reliability on delivery time and to maintain multiple sources for each raw material so that a quality or delivery problem with any one vendor will not adversely affect our operations. The quality and delivery
performance of each vendor is evaluated quarterly and quantity allocations are adjusted for subsequent periods based on the evaluation.

The most important raw material used in our production is silicon wafers, which is the basic raw material from which integrated circuits are made. The principal suppliers for our wafers are Shin-Etsu
Handotai and SUMCO Corporation of Japan, MEMC Electronic Materials, Inc. of the United States, Siltronic AG of Germany and Formosa Sumco Technology Corporation of Taiwan. Together they supplied approximately 96.7%, 96.8% and 96.0% of our total wafer
needs in 2009, 2010 and 2011, respectively. We have in the past obtained, and believe we will continue to be able to obtain, a sufficient supply of 150mm, 200mm and 300mm wafers. Please see Item 3. Key Information - Risk Factors - Risks
Relating to Our Business for a discussion of the risk related to raw materials. The price of silicon wafers decreased during 2009 due to the severe economic downturn. However, the continued market recovery after 2009 has increased demand. The
2011 Tohoku earthquake and tsunami also resulted in a tighter supply in silicon wafers and a higher price for such items. In order to secure a reliable and flexible supply of high quality wafers, we have entered into long-term agreements and intend
to continue to develop strategic relationships with major wafer vendors to cover our anticipated wafer needs for the next three to five years. Also, we have established a special cross-function taskforce comprised of individuals from our fab
operations, materials management, risk management and quality system management divisions to reduce our supply chain risks. This taskforce works with our primary suppliers to develop their business continuity plans, qualify their dual-plant
materials, prepare safety inventories, improve the quality of their products and manage the supply chain risk of their suppliers.

Competition

We compete internationally and domestically with dedicated foundry service providers, as well as with integrated device manufacturers that devote a significant portion of their manufacturing capacity to
foundry operations. We compete primarily on the basis of process technologies, manufacturing excellence and customer service. The level of competition differs according to the process technologies involved. For example, in more mature technologies,
the competition tends to be more intense. Some companies compete with us in selected geographic regions or application end markets. In recent years, substantial investments have been made by others to establish new dedicated foundry companies
worldwide.

Environmental Regulations

The semiconductor production process generates gaseous chemical wastes, liquid wastes, wastewater and other industrial wastes in various stages of the manufacturing process. We have installed in our fabs
various types of pollution control equipment for the treatment of gaseous chemical wastes and wastewater and equipment for the recycling of treated water. Operations at our fabs are subject to regulation and periodic monitoring by the R.O.C.
Environmental Protection Administration, the U.S. Environmental Protection Agency or the State Environmental Protection Administration of mainland China, and local environmental protection authorities, including the various science park
administrations in the R.O.C., the Washington State Department of Ecology or the Shanghai Environmental Protection Bureau.

We
have adopted pollution control measures that are expected to result in the effective maintenance of environmental protection standards consistent with the practice of the semiconductor industry in Taiwan, the U.S. and mainland China. We conduct an
annual environmental audit to ensure that we are in compliance in all material respects with, and we believe that we are in compliance in all material respects with, applicable environmental laws and regulations.

Electricity and Water

We use electricity supplied by the Taiwan Power Company in our manufacturing process. Businesses in the Hsinchu Science Park, Tainan
Science Park and Central Taiwan Science Park, such as ours, enjoy preferential electricity supply. We have sometimes suffered power outages caused by difficulties encountered by our electricity supplier, the Taiwan Power Company, which have led to
interruptions in our production schedule. The semiconductor manufacturing process also uses extensive amounts of fresh water. Due to the growth of the semiconductor manufacturers in the Hsinchu Science Park, Tainan Science Park and Central Taiwan
Science Park, and the droughts that Taiwan experiences from time to time, there is concern regarding future availability of sufficient fresh water and the potential impact that insufficient water supplies may have on our semiconductor production.

Risk Management

We employ an enterprise risk management system to integrate the prevention and control of risk that TSMC or our subsidiaries may face. We have also prepared emergency plans to respond to natural disasters
and other disruptive events that could interrupt the operation of our business. These emergency plans have been developed in order to prevent or minimize the loss of personnel or damage to our facilities, equipment and machinery caused by natural
disasters and other disruptive events. We also maintain insurance with respect to our facilities, equipment and inventories. The insurance for the fabs and their equipment covers, subject to some limitations, various risks, including fire, typhoons,
earthquakes and other risks generally up to the respective policy limits for their replacement values and lost profits due to business interruption. In addition, we have insurance policies covering losses with respect to the construction of all our
fabs. Equipment and inventories in transit are also insured. No assurance can be given, however, that insurance will fully cover any losses and our emergency response plans will be effective in preventing or minimizing losses in the future.

For further information, please see detailed risk factors related to the impact of climate change regulations and
international accords, and business trends on our operations in Item 3. Key Information - Risk Factors - Risks Relating to Our Business.

Overview

We manufacture a variety of semiconductors based on designs
provided by our customers. Our business model is commonly called a dedicated semiconductor foundry. The foundry segment of the semiconductor industry as a whole experienced rapid growth over the last 25 years since our inception. As the
leader of the foundry segment of the semiconductor industry, our net sales and net income were NT$295,742 million and NT$89,218 million in 2009, NT$419,538 million and NT$161,605 million in 2010, and NT$427,081 million (US$14,109 million) and
NT$134,201 million (US$4,434 million) in 2011, respectively. The sales in 2010 increased by 41.9% from 2009, mainly due to continuous growth in the semiconductor industry and customer demand, partially offset by the effect of U.S. dollar
depreciation and a decline in ASP. Our sales in 2011 increased slightly by 1.8% from 2010, mainly due to growth in customer demand and more favorable product mix, partially offset by the effect of U.S. dollar depreciation.

The principal source of our revenue is wafer fabrication, which accounted for approximately 90% of our net sales in 2011. The rest of our
net sales were derived from design, mask making, probing, and testing and assembly services. Factors that significantly impact our revenue include:



| |  |  | the worldwide demand for semiconductor products;
| | - |  | ------------------------------------------------



| |  |  | pricing;
| | - |  | --------



| |  |  | the worldwide semiconductor production capacity as well as our production capacity;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | capacity utilization;
| | - |  | ---------------------



| |  |  | availability of raw materials and supplies;
| | - |  | -------------------------------------------



| |  |  | technology migration; and
| | - |  | -------------------------



| |  |  | fluctuation in foreign currency exchange rate.
| | - |  | ----------------------------------------------

Though equally important, three of the above factors are discussed as follows:

Pricing. We establish pricing levels for a specific period with our customers, subject to adjustment during the course of
that period to take into account market developments and other factors. We believe that our large capacity, flexible manufacturing capabilities, focus on customer service and ability to deliver high yields in a timely manner have contributed to our
ability to obtain premium pricing for our wafer production.

Production Capacity.Our production capacity
affects our business as follows:

We currently own and operate our semiconductor manufacturing facilities, the aggregate
production capacity for which had been expanded from 869,977 200mm equivalent wafers per month as of the end of 2009 to 1,036,871 200mm equivalent wafers per month as of the end of 2010 and 1,163,708 200mm equivalent wafers per month as of the end
of 2011.

Critical
Accounting Policies

Summarized below are our accounting policies that we believe are important to the portrayal of our
financial results and also 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 revenue when evidence of an arrangement exists, the rewards of ownership and significant
risk of the goods have been transferred to the buyer, price is fixed or determinable, and the collectability is reasonably assured. We record a provision for estimated future returns and other allowances in the same period the related revenue is
recorded. Provision for estimated sales returns and other allowances is generally made and adjusted at a specific percentage based on historical experience, our managements judgment, and any known factors that would significantly affect the
allowance, and our management periodically reviews the adequacy of the percentage used. However, because of the inherent nature of estimates, actual returns and allowances could be different from our estimates. If the actual returns are greater than
our estimated amount, we could be required to record an additional provision, which would have a negative impact on our recorded revenue and gross margin.

As of December 31, 2009, 2010 and 2011, the amount recorded as sales returns and allowances in the accompanying consolidated statements of income was NT$13,913 million, NT$12,093 million and NT$3,410
million (US$113 million), respectively, representing 4.5%, 2.8% and 0.8% of our gross sales for the years ended December 31, 2009, 2010 and 2011. The higher percentage in 2009 was mainly attributed to higher sales incentives offered to certain
customers in 2009 due to the economic downturn, compounded by an increased level of credits to customers for product related issues. The decline in 2010 percentage was the result of over 40% growth in sales, lower sales incentives offered as
compared to 2009 and a return of our product related issues back to normal level. The 2011 percentage was further reduced as both sales incentives and product related issues were reduced.

Allowance for Doubtful Accounts. We determine provision for doubtful accounts by examining our historical collection
experience and current trends in the credit quality of our customers as well as our internal credit policies. If economic conditions or financial conditions of our customers deteriorate, additional allowance may be required in the future and such
additional allowance would increase our operating expenses and therefore reduce our operating income and net income.

##### Table of Contents

Prior to January 1, 2011, we record provision for doubtful accounts based on a
percentage of accounts receivable due from our customers. Effective on January 1, 2011, we evaluate for indication of impairment of accounts receivable based on an individual and collective basis at the end of each reporting period according to
the third revision of Statement of Financial Accounting Standards (SFAS) No. 34. When objective evidence indicates that the estimated future cash flow of accounts receivable decreases as a result of one or more events that occurred after the
initial recognition of the accounts receivable, such accounts receivable are deemed to be impaired.

Because of the short
average collection period, the amount of the impairment loss recognized is the difference between the carrying amount of accounts receivable and estimated future cash flows without considering the discounting effect. Changes in the carrying amount
of the allowance account are recognized as bad debt expense which is recorded in the operating expenses - general and administrative. When accounts receivable are considered uncollectable, the amount is written off against the allowance account.

As of December 31, 2010 and 2011, the allowance set aside for doubtful receivables was NT$504 million and NT$491 million
(US$16 million), respectively, representing 1.0% and 1.1% of our gross notes and accounts receivables as of those dates.

Inventory valuation.Inventories are stated at the lower of cost or net realizable value for finished goods,
work-in-progress, raw materials, supplies and spare parts. Inventory write-downs are made on an item-by-item basis, except where it may be appropriate to group similar or related items.

A significant amount of our manufacturing costs are fixed because our extensive manufacturing facilities (which provide us such large
production capacity) require substantial investment to construct and are largely fixed-cost assets once they become operational. When the capacity utilization increases, the fixed manufacturing costs are spread over a larger amount of output, which
would lower the inventory cost per unit thereby improving our gross margin.

We evaluate our ending inventory based on
standard cost under normal capacity utilization, and reduce the carrying value of our inventory when the actual capacity utilization is higher than normal capacity utilization. No adjustment is made to the carrying value of inventory when the actual
capacity utilization is at or lower than normal capacity utilization. Normal capacity utilization is established based on historic loadings compared to total available capacity in our wafer manufacturing fabs.

Due to rapid technology changes, we also evaluate our ending inventory and reduce the carrying value of inventory for estimated
obsolescence and unmarketable inventory by an amount that is the difference between the cost of the inventory and the net realizable value. The net realizable value of the inventory is mainly determined based on assumptions of future demand within a
specific time horizon, which is generally 180 days or less.

Valuation allowance for deferred tax assets.When
we have net operating loss carry forwards, investment tax credits or temporary differences in the amount of tax recorded for tax purposes and accounting purposes, we may be able to reduce the amount of tax that we would otherwise be required to pay
in future periods. We recognize all existing future tax benefits arising from these tax attributes as deferred tax assets and then establish a valuation allowance equal to the extent, if any, that it is more likely than not that such deferred tax
assets will not be realized. We record an income tax benefit or expense when there is a net change in our total deferred tax assets and liabilities in a period. The ultimate realization of the deferred tax assets depends upon the generation of
future taxable income during the periods in which the net operating losses and temporary differences become deductible or the investment tax credits may be utilized. Specifically, our valuation allowance is impacted by our expected future revenue
growth and profitability, tax holidays, Alternative Minimum Tax, 10% tax imposed on unappropriated earnings and the amount of tax credits that can be utilized within the statutory period. In determining the amount of valuation allowance for deferred
tax assets as of December 31, 2011, we considered past performance, the general outlook of the semiconductor industry, business conditions, future taxable income and prudent and feasible tax planning strategies.

Because the determination of the amount of valuation allowance is based, in part, on our forecast of future profitability, it is
inherently uncertain and subjective. Changes in market conditions and our assumptions may cause the actual future profitability to differ materially from our current expectation, which may require us to increase or decrease the amount of valuation
allowance that we have recorded.

As of December 31, 2010 and 2011, the ending balances for valuation allowance were
NT$16,423 million and NT$13,531 million (US$447 million), respectively, representing 56.3% and 50.3% of gross deferred tax assets as of those dates. In 2011, we evaluated the effect of Alternative Minimum Tax and the application of tax exemptions
for a five-year period. As we plan to apply the tax-exempt income in later years, income tax payable is anticipated to increase and we will utilize available investment tax credits as an offset against income taxes. Since more investment tax credits
can be utilized, valuation allowance has been adjusted down in 2011 accordingly.

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. Our long-lived
assets subject to this evaluation include property, plant and equipment and amortizable intangible assets. Factors we consider important which could trigger an impairment review include, but are not limited to, the following:



| |  |  | significant under performance relative to historical or projected future operating results;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | significant changes in the manner of our use of the acquired assets or our overall business strategy; and
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | significant unfavorable industry or economic trends.
| | - |  | ----------------------------------------------------

When we determine that the carrying value of intangible assets and other long-lived assets may not be recoverable based upon the existence of one or more of the above indicators of impairment, we measure
any impairment for long-lived assets based on a projected future cash flow. If the long-lived or intangible assets that are determined to be impaired, we recognize an impairment loss through a charge to our operating results to the extent the
present value of discounted cash flows attributable to the assets are less than their carrying value. Such cash flow analysis includes assumptions about expected future economic and market conditions, the applicable discount rate, and the future
revenue generation from the use or disposition of the assets. We also perform a periodic review to identify assets that are no longer used and are not expected to be used in future periods. An impairment charge is recorded to the extent, if any,
that the carrying amount of the idle assets exceeds their fair value. Under R.O.C. GAAP, if the recoverable amount increases in a future period, the amount previously recognized as impairment will 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. Under U.S. GAAP, the reversal of impairment charges is prohibited.

The process of evaluating the potential impairment of long-lived assets requires significant judgment. We are required to review for
impairment groups of assets related to the lowest level of identifiable independent cash flows. Due to our asset usage model and the interchangeable nature of our semiconductor manufacturing capacity, we must make subjective judgments in determining
the independent cash flows that can be related to specific asset groups. In addition, because we must make subjective judgments regarding the remaining useful lives of assets and the expected future revenue and expenses associated with the assets,
changes in these estimates based on changed economic conditions or business strategies could result in material impairment charges in future periods. Our projection for future cash flow is generally less during periods of reduced earnings. As a
result, an impairment charge is more likely to occur during a period when our operating results are already otherwise depressed.

For purposes of evaluating the recoverability of long-lived assets, assets purchased for use in the business but subsequently determined to have no future economic benefits are written down to their fair
value and recorded as either idle assets or assets held for disposition. In 2010 and 2011, an impairment loss for idle assets of NT$0.3 million and NT$98 million (US$3 million) was recorded, respectively. No impairment loss for idle assets was
recorded in 2009. As of December 31, 2010 and 2011, net long-lived assets and intangible assets amounted to NT$394,471 million and NT$495,542 million (US$16,371 million), respectively.

Goodwill. Goodwill is recorded when the purchase price paid for an acquisition
exceeds the estimated fair value of the net identified tangible and intangible assets acquired. Under U.S. GAAP, and effective on January 1, 2005 under R.O.C. GAAP, we assess the impairment of goodwill on an annual basis, or more frequently
whenever triggering events or changes in circumstances indicate that goodwill may be impaired and carrying value may not be recoverable. Moreover, effective on January 1, 2006, goodwill is no longer amortizable under R.O.C. GAAP. Factors we
consider important which could trigger an impairment review include, without limitation, the following:



| |  |  | significant decline in our stock price for a sustained period; and
| | - |  | ------------------------------------------------------------------



| |  |  | significant decline in our market capitalization relative to net book value.
| | - |  | ----------------------------------------------------------------------------

Application of the goodwill impairment test is also highly subjective and requires significant judgment, including the identification of
cash generating units, assigning assets and liabilities to the relevant cash generating units, assigning goodwill to the relevant cash generating units, and determining the fair value of the relevant cash generating units. Our assessment of fair
value is based upon a cash flow analysis that includes assumptions about expected future operating performance, such as revenue growth rates and operating margins, risk-adjusted discount rates, future economic and market conditions, and
determination of appropriate market comparables. Under R.O.C. GAAP, the fair value of the cash generating units is compared to the associated carrying value including goodwill. On the other hand, under U.S. GAAP, the fair value of the reporting
units is compared to the associated carrying value including goodwill.

Under R.O.C. GAAP, goodwill recorded from the
acquisition of TSMC-Acer and WaferTech is evaluated for impairment on an annual basis. Based on our most recent evaluation, the fair value calculated by discounting projected cash flow in five years was higher than the associated carrying value. As
a result, we did not record any impairment charge under R.O.C. GAAP. Under U.S. GAAP, goodwill recorded from the acquisition of TSMC-Acer and WaferTech is evaluated for impairment on an annual basis. Based on our most recent evaluation, the fair
value calculated by using the discounted cash flow method was higher than the associated carrying value. As a result, we did not record any impairment charge under U.S. GAAP either.

As of December 31, 2010 and 2011, goodwill amounted to NT$5,705 million and NT$5,694 million (US$188 million), respectively, under
R.O.C. GAAP. The change in the NT dollar amount of goodwill was due to changes in the exchange rate between NT dollar and U.S. dollar.

Valuation of investments accounted for using the equity method. 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 a projected future cash flow of the investees, the underlying assumptions for which had been formulated by such
investees internal management team, taking into account market conditions for the industries which the investees operate in to ensure the reasonableness of such assumptions. If an investment is determined to be impaired, we recognize an
impairment loss through a charge to our operating results to the extent the present value of discounted cash flows attributable to the investee is less than the carrying value of the investment.

For the years ended December 31, 2009, 2010 and 2011, no impairment loss was recorded as the value determined based on the
discounted cash flow of the investees was higher than the carrying value of the investments accounted for using the equity method.

Accounting for investments in private and publicly-traded securities. We hold equity interests in companies, some of which are publicly traded and have highly volatile share prices. We also
hold investments in debt securities, such as corporate bonds, government bonds, and etc. We review all of our investments for impairment quarterly and record an impairment charge when we believe an investment has experienced an other-than-temporary
decline in value. Determining whether an other-than-temporary decline in value of the investment has occurred is highly subjective. Such evaluation is dependent on the specific facts and circumstances. Factors we consider include, but are not
limited to, the following: the market value of the security in relation to its cost basis, the duration of the decline in value, the financial condition of the investees and our intent and ability to retain the investment for a sufficient period of
time to allow for recovery in the market value of the investment. Impairment reviews with respect to private security investments also require significant judgment. Factors indicative of an other-than-temporary decline in value include recurring
operating losses, credit defaults and subsequent rounds of financing at valuation below the cost basis of the investment.

We
have experienced declines in the value of certain privately held investments and publicly traded securities and recorded impairment loss of NT$913 million, NT$160 million and NT$266 million (US$9 million) in 2009, 2010 and 2011, respectively. While
we have recognized all declines that are currently believed to be other-than-temporary as a charge to income, adverse changes in market conditions or poor operating results of underlying investments could result in further losses in future periods.

Net Sales

Our net sales in 2011 increased by 1.8% from 2010, which was mainly attributable to the growth in customer demand. The overall wafer shipments increased by 5.8%, from 11,860 thousand 200mm equivalent
wafers in 2010 to 12,549 thousand 200mm equivalent wafers in 2011. Furthermore, we had a more favorable product mix in 2011 as the portion of wafer sales from 65 nanometer and below circuit resolutions reached 56% compared to 46% in 2010.
However, as a significant portion of our sales were denominated in U.S. dollars, our net sales in 2011 were negatively impacted by a stronger weighted average NT dollar against U.S. dollar, which appreciated against the U.S. dollar by 6.7% to
NT$29.367 to US$1.00 in 2011 from NT$31.491 to US$1.00 in 2010.

Our net sales in 2010 increased by 41.9% from 2009, which was largely due to the overall
growth in industry and customer demand. The overall wafer shipments increased by 53.3%, from 7,737 thousand 200mm equivalent wafers in 2009 to 11,860 thousand 200mm equivalent wafers in 2010. However, as a significant portion of our sales
were denominated in U.S. dollars, our net sales in 2010 were negatively impacted by a stronger weighted average NT dollar against the U.S. dollar, which appreciated by 4.2% to NT$31.491 to US$1.00 in 2010 from NT$32.868 to US$1.00 in 2009.
Furthermore, our ASP declined in 2010.

Gross Margin

Our gross margin fluctuated with the level of capacity utilization, price change and product mix, among other factors. In 2011, our gross margin decreased to 45.4% of net sales from 49.4% of net sales in
2010. The lower margin in 2011 was primarily due to lower capacity utilization as we increased our capacity in 2011, price decline and a stronger NT dollar against the U.S. dollar, which negatively impacted our gross margin by 7.1, 2.8 and 2.4
percentage points, respectively, offset in part by cost improvements and others which contributed favorably to a 8.3 percentage points increase in the gross margin.

In 2010, our gross margin increased to 49.4% of net sales from 43.7% of net sales in 2009. The higher margin in 2010 was primarily due to higher capacity utilization and cost reductions, which contributed
favorably to 6.8 and 3.6 percentage points increase, respectively, in the gross margin, offset in part by price declines and a stronger NT dollar against the U.S. dollar, which negatively impacted our gross margin by 3.6 and 1.5 percentage points,
respectively.

Operating expenses increased by NT$4,633 million in 2011, or 9.7%, from NT$47,879 million in 2010, after
an increase in operating expenses of NT$10,512 million in 2010, or 28.1%, from 2009.

Research and Development Expenses

We remain strongly committed to being the leader in developing advanced process technologies. We believe that continued
investments in process technologies are essential for us to remain competitive in the markets we serve. Research and development expenditures increased by NT$4,123 million in 2011, or 13.9%, from 2010, mainly due to higher spending in further
developing 20nm technology, partially offset by lower employee profit sharing expenses and bonus. In 2010, research and development expenditures increased by NT$8,114 million, or 37.6%, from 2009, mainly reflecting higher spending in further
developing 28nm and 20nm technologies and higher employee profit sharing expenses and bonuses in 2010. We plan to continue to invest significant amounts in research and development in 2012.

General and Administrative, Sales and Marketing Expenses

General and administrative, sales and marketing expenses in 2011 increased by NT$510 million, or 2.8% from 2010, due to an increase in general and administrative expenses by NT$1,360 million, or 10.6%,
and a decrease of sales and marketing expenses by NT$850 million, or 15.8%. The net increase was primarily due to higher opening expenses for Fab15 (Phase I) and Fab10 (Phase II), partially offset by lower employee profit sharing expenses and bonus
in 2011.

##### Table of Contents

General and administrative, sales and marketing expenses in 2010 increased by NT$2,398
million, or 15.2%, from 2009, due to an increase in general and administrative expenses and sales and marketing expenses by NT$1,518 million and NT$880 million, or 13.5% and 19.6%, respectively. The increase was mainly due to higher employee profit
sharing expenses and bonuses in 2010, higher labor costs due to business scale expansion, and more opening expenses for Fab14 (Phase IV) and Fab12 (Phase V), partially offset by lower legal fees due to litigation concluded in 2009.

Net non-operating income in 2011 decreased by NT$7,504 million, or 67.6% from NT$11,095 million in 2010
primarily due to a NT$5,993 million decrease in settlement income from SMIC as we received less settlement payment in cash and absence of receipt of SMIC shares in 2011 pursuant to the settlement agreement. In addition, equity in earnings of equity
method investees declined by NT$1,400 million as a result of weakened operating performance of such equity method investees in 2011.

Net non-operating income in 2010 increased by NT$7,594 million, or 216.9%, from NT$3,501 million in 2009 primarily due to a NT$5,475 million increase in settlement income from SMIC, a NT$2,252 million
increase in equity in earnings of equity method investees, a NT$753 million decrease in loss on impairment of financial assets and a NT$721 million increase in net gain on settlement and disposal of financial assets, partially offset by a NT$936
million decrease in interest income and a NT$781 million increase in loss on disposal of property and equipment. Equity in earnings generated from equity method investees increased, reflecting business improvement of such equity method investees in
2010. The decrease in loss on impairment of financial assets was primarily due to an increase in the fair value of financial assets in 2010. The increase in net gain on settlement and disposal of financial assets was mainly due to higher disposal
gain on debt and equity securities. Interest income decreased primarily due to lower interest rates in 2010. The increase in loss on disposal of property and equipment mainly resulted from the disposal of steel frame in a newly-acquired,
partially-constructed memory fab.

##### Table of Contents

Income tax expenses increased by NT$2,707 million in 2011, or 33.9%, from 2010. The increase
was mainly related to increase in tax on unappropriated earnings as a result of higher unappropriated earnings in 2011 compared to 2010.

Income tax expenses increased by NT$1,991 million in 2010, or 33.2%, from 2009. The increase was mainly due to an increase in taxable income, partially offset by lower statutory tax rate, from 25% to 17%.
See  Taxation below for further discussion.

Liquidity and Capital Resources

Our sources of liquidity include cash flow from operations, cash and cash equivalents, short-term investments and revolving credit
facilities provided by multiple banks.

Our primary source of liquidity is cash flow from operations. Cash flow from
operations for 2011 was NT$247,587 million (US$8,179 million), an increase of NT$18,111 million from 2010.

Our cash, cash
equivalents and current investments in financial instruments amounted to NT$150,622 million (US$4,976 million) as of December 31, 2011, down from NT$181,574 million as of December 31, 2010. The current investments in financial instruments
primarily consist of corporate bonds, publicly-traded stocks, government bonds, and money market funds.

As of
December 31, 2011, we also had an aggregate unused short-term credit lines of approximately NT$63,708 million (US$2,105 million) and an aggregate unused long-term credit lines of approximately NT$2,050 million (US$68 million).

We believe that our cash generated from operations, cash and cash equivalents, short-term investments, ability to access capital market
and revoling credit facilities will be sufficient to fund our working capital needs, capital expenditures, dividend payments and other business requirements associated with existing operations over the next 12 months.

Cash and cash equivalents decreased by NT$4,415 million in 2011, or 3.0%, from 2010, following a decrease
of NT$23,389 million in 2010, or 13.7%, from 2009.

Operating Activities

In 2011, we generated NT$247,587 million (US$8,179 million) net cash from operating activities, as compared to NT$229,476 million and
NT$159,966 million in 2010 and 2009, respectively. In 2011, net cash generated from operating activities increased primarily due to an increase of NT$19,872 million in non-cash depreciation and amortization expenses, the absence of non-cash gain of
NT$4,434 million from SMIC shares received as litigation compensation and from change in inventories and notes and accounts receivables, partially offset by a decrease of NT$27,404 million in net income.

In 2010, net cash generated from operating activities increased primarily due to an increase of NT$72,387 million in net income and an
increase of NT$6,995 million in non-cash depreciation and amortization expenses, partially offset by the NT$5,341 million change in accrual for employee profit sharing and bonus and non-cash gain from SMIC shares as litigation compensation in the
amount of NT$4,434 million.

In 2011, depreciation and amortization expenses were NT$107,682 million (US$3,557 million), as
compared to NT$87,810 million and NT$80,815 million in 2010 and 2009, respectively. Higher depreciation and amortization expenses in 2011 and 2010 were mainly attributable to increase in capital expenditures to expand production capacity in advanced
technologies.

Investing Activities

In 2011, net cash used in investing activities was NT$182,523 million (US$6,030 million), as compared to NT$202,086 million and NT$96,468
million in 2010 and 2009, respectively. The decrease in 2011 was primarily due to lower investment in financial assets, higher disposal or redemption of investment in financial assets, lower refundable deposits and the absence of new investment in
equity method investees, partially offset by higher spending on capital expenditures during the year. The increase in 2010 was primarily due to the significantly higher spending on capital expenditures, an increase in investment in equity method
investees and an increase in refundable deposits, partially offset by higher amount of cash received from disposal or redemption of investments in financial assets during the year.

Capital expenditures in 2011 were primarily related to:



| |  |  | adding production capacity to 300mm and 200mm wafer fabs;
| | - |  | ---------------------------------------------------------



| |  |  | expanding buildings/facilities for Fab 12, Fab 14 and Fab 15;
| | - |  | -------------------------------------------------------------



| |  |  | developing process technologies including 28nm node and below;
| | - |  | --------------------------------------------------------------



| |  |  | capacity expansion for mask and backend operations;
| | - |  | ---------------------------------------------------



| |  |  | other research and development projects; and
| | - |  | --------------------------------------------



| |  |  | solar and solid state lighting businesses.
| | - |  | ------------------------------------------

During the past few years, our capital expenditures were funded by our operating cash flow. The capital expenditures for 2012 are also expected to be funded by our operating cash flow. See Item 4.
Information on the Company  Capacity Management and Technology Upgrade Plans for discussion of our capacity management and capital expenditures.

Financing Activities

In 2011, net cash used in financing activities was
NT$67,858 million (US$2,242 million), as compared to NT$48,638 million and NT$85,471 million in 2010 and 2009, respectively. In 2011, net cash used in financing activities increased primarily due to the change from NT$31,214 million cash provided by
short-term loans in 2010 to NT$5,287 million cash used to repay short-term loans in 2011 and the higher repayment of other long-term liabilities of NT$2,526 million, partially offset by the proceeds from issuance of corporate bonds amounting to
NT$18,000 million and increase in long-term debts of NT$2,250 million. In 2010, net cash used in financing activities decreased primarily due to an increase of NT$31,214 million in short-term debt mainly to naturally hedge a portion of our accounts
receivable denominated in U.S. dollars and the repayment in 2009 of corporate bonds amounting to NT$8,000 million, partially offset by repayment in 2010 of other long-term liabilities of NT$1,107 million.

As of December 31, 2011, our short-term loans were NT$25,927 million (US$856 million, translated from 2011 year-end revaluation
exchange rate of NT$30.288 to US$1.00), and our aggregate long-term debt was NT$24,150 million (US$798 million) of which NT$4,563 million (US$151 million) was classified as current. The short-term loans were denominated in U.S. dollars. To protect
against reductions in value and the volatility of asset value caused by changes in foreign exchange rates, we utilized short-term loans and derivative financial instruments, including currency forward contracts and cross currency swaps, to hedge our
currency exposure. See Item 11. Quantitative and Qualitative Disclosures About Market Risk for a discussion of the hedging instruments used. The long-term debt included NT$22,500 million of the long-term bonds with fixed interest rates
ranging from 1.40% to 3.00%.

|(1) | The maximum amount and average amount of short-term loans outstanding during the year ended December 31, 2011 were NT$36,020 million and NT$33,582 million,
respectively. The purpose of the short-term loans was mainly to naturally hedge a portion of our accounts receivable. As a substantial portion of our accounts receivable was denominated in U.S. dollars, we use short-term loans denominated in U.S.
dollars to naturally hedge the fluctuation of foreign exchanges rates. See note 16 to our consolidated financial statements for further information regarding interest rates and future repayment dates.

During 2011, we entered into derivative financial instruments transactions to manage exposures related to foreign-currency denominated
receivables or payables and interest rate fluctuations. As of December 31, 2011, we anticipated our cash requirements in 2012 for outstanding forward exchange agreements and cross currency swaps of approximately NT$584 million, RMB1,119
million, EUR39 million, and US$22 million with our expected cash receipts of approximately JPY260 million, US$196 million, and NT$2,038 million, and EUR2 million. See Item 11. Quantitative and Qualitative Disclosures about Market Risk
for more information regarding our derivative financial instruments transactions. See also note 2 to the consolidated financial statements for our accounting policy of derivative financial instruments, and note 6 and note 26 to the consolidated
financial statements for additional details regarding our derivative financial instruments transactions.

Generally, we do not provide letters of credit to, or guarantees for any entity other than
our consolidated subsidiaries.

Significant amounts of capital are required to build, expand, and upgrade our production
facilities and equipment. Our capital expenditures for 2012 are expected to be approximately US$6 billion, which, depending on market conditions, may be adjusted upwards later.

U.S. GAAP Reconciliation

Our consolidated financial statements are

Differences between R.O.C. GAAP and U.S. GAAP that have a material effect on our net income and
shareholders equity as reported under R.O.C. GAAP include compensation expense pertaining to stock bonuses to employees, recognition of and subsequent accounting for goodwill, 10% tax imposed on unappropriated earnings, stock-based
compensation and deconsolidation of investees. Please refer to note 34 to the consolidated financial statements, which provides a description of the principal differences between R.O.C. GAAP and U.S. GAAP as they relate to us and a reconciliation to
U.S. GAAP of certain items, including net income and shareholders equity.

Taxation

In 2010, the R.O.C. government reduced the corporate income tax rate from 25% to 17% effective from 2010. In the same year, the
Statute for Industries Innovation was passed to replace the Statute for Upgrading Industries in tax incentives. Under the new statute, the research and development expenditure tax credit rate was reduced from 30% to 15%, and
the 7% tax credit incentive for purchased equipment was terminated.

We are eligible for five-year tax holidays for income
generated from construction and capacity expansions of production facilities according to the regulation under the Statute for Upgrading Industries of the R.O.C. The exemption period may begin at any time within five years, as applicable, following
the completion of a construction or expansion of production facilities. The aggregate tax benefits of such exemption periods in 2009, 2010 and 2011 were NT$8,652 million, NT$17,410 million and NT$13,832 million (US$457 million), respectively. We
commenced the exemption period for part of Fab 14 (Phase III), part of Fab 12 (Phase III) and others in 2010; part of Fab 12 (Phase IV), part of Fab 14 (Phase III and IV) in 2011. The Statute for Upgrading Industries expired at the end of 2009.
However, under the Grandfather Clause, we can continue to enjoy five-year tax holidays if the relevant investment plans were approved by R.O.C. tax authority before the expiration of the Statute.

Under regulations promulgated under the R.O.C. Statute for Industries Innovation, we were eligible for a tax credit for specified
percentages of research and development expenditures. The tax credit rate of research and development expenditures is 15% during the period from 2010 to 2019.

The R.O.C. government enacted the R.O.C. Alternative Minimum Tax Act (AMT Act) which became effective on January 1, 2006. The alternative minimum tax (AMT) imposed under the
R.O.C. AMT Act is a supplemental tax which is payable if the income tax payable pursuant to the R.O.C. Income Tax Act is below the minimum amount prescribed under the R.O.C. AMT Act. The taxable income for calculating the AMT includes most income
that is exempted from income tax under various legislations, such as tax holidays and investment tax credits. The AMT rate for business entities is 10%. However, the R.O.C. AMT Act grandfathered certain tax exemptions and tax credits granted prior
to the enactment of the R.O.C. AMT. We currently expect the AMT to have a small effect on our income tax expense in 2012.

Off-Balance Sheet Arrangements

There are no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial
condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

Inflation & Deflation

During 2011, neither inflation nor
deflation had a material impact on our operations, or the business operations of our customers and suppliers. However, with uncertain global economy outlook, we cannot assure that there will be no significant variations in the future, which may have
a material impact on our results of operations.

Recent Accounting Pronouncements

For R.O.C. GAAP, please refer to note 4 to the consolidated financial statements. For U.S GAAP, please refer to note 35 to the
consolidated financial statements.

Climate Change Related Issues

The manufacturing, assembling and testing of our products require the use of chemicals and materials that are subject to environmental,
climate related, health and safety laws and regulations issued worldwide as well as international accords such as the Kyoto Protocol. Climate change related laws or regulations currently are too indefinite for us to assess the impact on our future
financial condition with any degree of reasonable certainty. For example, the Taiwan legislative authority has been studying relevant laws relating to environmental protection and climate related changes, such as the Greenhouse Gas Reduction
Act and Energy Tax. Since there has been no concrete guidance or laws issuing from the Taiwan government as of the date of this filing, the impact of such laws is indeterminable at the moment. Please see detailed risk factors
related to the impact of climate change regulations and international accords, and business trends on our operations in Item 3. Key Information - Risk Factors - Risks Relating to Our Business. Please also see our compliance record with
Taiwan and international environmental and climate related laws and regulations in Item 4. Information on the Company  Environmental Regulation.

Directors and Executive Officers

MANAGEMENT

Members of our board of directors are elected by our shareholders. Our board of directors is currently composed of nine directors. Of our
current nine directors, five are independent directors. The chairman of the board of directors is elected by the directors. The chairman of the board of directors presides at all meetings of the board of directors, and also has the authority to act
as our representative. The term of office for directors is three years.

Pursuant to R.O.C. Securities and Exchange Law,
effective from January 1, 2007, a public company is required to either establish an audit committee or to have supervisors. A public companys audit committee should be composed of all of its independent directors but not less than three,
of which at least one member should have accounting or related financial management expertise, and the relevant provisions under the R.O.C. Securities and Exchange Law, the R.O.C. Company Law and other laws applicable to the supervisors are also
applicable to the audit committee.

Prior to January 1, 2007, we had two supervisors. The supervisors major duties
and powers included, but were not limited to (i) investigation of our financial condition; (ii) inspection of corporate records; (iii) giving reports in connection with the companys financial statements at shareholders
meetings. Beginning from January 1, 2007, the duties and powers of our supervisors are being exercised by our Audit Committee which is composed of all of our independent directors, and supersedes and replaces the office of supervisors.

Pursuant to the R.O.C. Company Law, a person may serve as our director in his personal
capacity or as the representative of another legal entity. A director 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 may serve the
remainder of the term of office of the replaced director. For example, the National Development Fund of Taiwan, R.O.C., one of our largest shareholders, has served as our director since our founding. As a corporate entity, the National Development
Fund is required to appoint a representative to act on its behalf in discharging its directorial duties. Mr. Johnsee Lee has been our representative of the National Development Fund since August 6, 2010.

Currently, the Audit Committee consists of five members comprising all of our independent directors. The members of the Audit Committee
are Sir Peter Bonfield, the Chairman of our Audit Committee, Mr. Stan Shih, Mr. Thomas J. Engibous, Mr. Gregory C. Chow and Ms. Kok-Choo Chen. In addition, Mr. J. C. Lobbezoo was appointed to serve as financial

Audit Committee the authority to conduct any investigation which it deems appropriate to fulfill its responsibilities. It has direct access to all our books, records, facilities, and personnel, as well as our registered public accountants. It has
the authority to, among other things, appoint, terminate and approve all fees to be paid to our registered public accountants, subject to the approval of the board of directors as appropriate, and to oversee the work performed by the registered
public accountants. The Audit Committee also has the authority to engage special legal, accounting, or other consultants it deems necessary in the performance of its duties. Beginning on January 1, 2007, the Audit Committee also assumed the
responsibilities of supervisors pursuant to the R.O.C. Securities and Exchange Law.

As of December 31, 2011, our total employee population was 35,457 with an educational makeup of 3.5 %
Ph.Ds, 33.0% masters, 25.9% university bachelors, 13.8% college degrees and 23.8% others. Among this employee population, 48.7% were at a managerial or professional level. Continuous learning is the cornerstone of our employee development strategy.
Individual development plans for each employee are customized and tailored to their individual development needs. Employee development is further supported and enforced by a comprehensive and integrated network of resources including on-the-job
training, coaching, mentoring, job rotation, on-site courses, e-learning and external learning opportunities.

Pursuant to our
Articles of Incorporation, our employees participate in our profits by way of a bonus. Employees in the aggregate are entitled to not less than 1% of our net income after the deduction for prior years losses and contributions to legal and
special reserves. Our practice in the past has been to determine the amount of the bonus based on our operating results and industry practice in the R.O.C. In 2010 and 2011, we distributed an employees cash bonus of NT$ 10,908 million
(US$360 million) and an employees cash profit sharing of NT$10,908 million (US$360 million) to our employees in relation to year 2010 earnings. In 2011 and 2012, we also distributed an employees cash bonus of NT$8,990 million (US$297
million) to our employees in relation to year 2011 earnings.

In June 2002, we adopted the 2002 Employee Stock Option Plan
that authorizes the grant of options exercisable for up to 100 million common shares (approximately 0.5% of our total then outstanding common shares). These options vested between two and four years after the date of grant, with 50% of the
option granted being exercisable two years after the grant, 75% exercisable three years after the grant and 100% exercisable four years after the grant. Any options granted will expire ten years after the date of grant. Under the 2002 Employee Stock
Option Plan, a total of 48,137,264 options were granted, of which 2,726,796 options were originally granted to certain of our officers as a result of their voluntary election to exchange part of their profit sharing for stock options. The remaining
balance of options under the 2002 Employee Stock Option Plan expired on June 25, 2003. As of December 31, 2011, 10,584,755 options were outstanding under the 2002 Employee Stock Option Plan.

In September 2003, we adopted the 2003 Employee Stock Option Plan that authorizes the grant of the options exercisable for up to
120 million common shares (approximately 0.6% of our total then outstanding common shares) in one or more tranches before October 29, 2004, when the 2003 Employee Stock Option Plan expired. These options vested between two and four years
after the date of grant, with 50% of the options granted being exercisable two years after the grant, 75% exercisable three years after the grant and 100% exercisable four years after the grant. Any options granted will expire ten years after the
date of grant. Under the 2003 Employee Stock Option Plan, a total of 12,055,735 options have been granted. The remaining balance under the 2003 Employee Stock Option Plan expired on October 29, 2004. As of December 31, 2011, 1,576,377
options were outstanding under the 2003 Employee Stock Option Plan.

In November 2004, we adopted the 2004 Employee Stock Option Plan that authorizes the grant
of options exercisable for up to 11 million common shares (approximately 0.05% of our total then outstanding common shares) in one or more tranches before January 6, 2006, when the 2004 Employee Stock Option Plan expired. These options
will vest between two and four years after the date of grant, with 50% of the options granted being exercisable two years after the grant, 75% exercisable three years after the grant and 100% exercisable four years after the grant. Any options
granted will expire ten years after the date of grant. Under the 2004 Employee Stock Option Plan, a total of 10,374,550 options have been granted. The remaining balance under the 2004 Employee Stock Option Plan expired on January 6, 2006. As of
December 31, 2011, 2,132,422 options were outstanding under the 2004 Employee Stock Option Plan.

The following table
provides information with respect to outstanding stock options held by our current officers as of December 31, 2011 under the 2002 Employee Stock Option Plan. The numbers of the common shares underlying the stock options and the exercise prices

In order to attract qualified senior management, we maintain a sign-on bonus plan, under
which selected newly hired senior employees, upon approval by our senior management, receive a hiring bonus with the general condition of staying in our employment for at least one year (based on the quantum of sign-on bonus). In 2011, a total of
NT$15 million (US$0.5 million) was distributed to our senior management under our sign-on bonus plan.

We value two-way
communication and are committed to keeping our communication channels open and transparent between the management level and their subordinates. In addition, we are dedicated to providing diverse employee engagement programs, which support our goals
in reinforcing close rapport with employees and maintaining harmonious labor relations.

Related Party Transactions

Vanguard International Semiconductor Corporation

In 1994, we, the R.O.C. Ministry of Economic Affairs and other investors established Vanguard, then an integrated DRAM manufacturer. Vanguard commenced volume commercial production in 1995 and listed its
shares on the GreTai Securities Market in March 1998. In 2004, Vanguard completely terminated its DRAM production and became a pure-play foundry company. As of February 29, 2012, we owned approximately 38.8% of Vanguard.

On April 1, 2004, we entered into an agreement with Vanguard with an initial term of two years. During the term of this agreement,
Vanguard is obligated to use its best commercial efforts to manufacture wafers at specified yield rates for us up to a fixed amount of reserved capacity per month, and TSMC is required to use its best commercial efforts to maintain utilization of
such reserved capacity within a specified range of wafers per month. Pursuant to its terms, upon expiration of its initial two-year term, this agreement is to be automatically renewed for additional one year periods unless earlier terminated by the
parties. This Agreement has been so renewed per its terms. We pay Vanguard at a fixed discount to the actual selling price as mutually agreed between the parties in respect of each purchase order. We also agreed to license Vanguard certain of our
process technologies and transfer certain technical know-how and information. TSMC receives from Vanguard certain royalty payments for granting such licenses. In 2009, 2010 and 2011, we had total purchases of NT$3,330 million, NT$4,959 million, and
NT$5,598 million, (US$185 million) from Vanguard, representing 2.0%, 2.3% and 2.4% of our total cost of sales, respectively.

Systems on Silicon Manufacturing Company Pte. Ltd. (SSMC)

SSMC is a joint venture in Singapore that we established with Philips and EDB Investment Pte. Ltd. to produce integrated circuits by
means of advanced submicron manufacturing processes. These integrated circuits are made pursuant to the product design specifications provided primarily by us and Philips under an agreement with Philips, and EDB Investment Pte. Ltd. (the SSMC
Shareholders Agreement) in March 1999 and, primarily by us and NXP, subsequent to the assignment by Philips of its rights to NXP and NXPs assumption of Philips obligations under the SSMC Shareholders Agreement pursuant to the
Assignment and Assumption Agreement effective September 25, 2006. SSMCs business is limited to manufacturing wafers for us, our subsidiaries, NXP and NXPs subsidiaries. In November 15, 2006, we and NXP exercised the option
rights under the SSMC Shareholders Agreement to purchase all of the SSMC shares owned by EDB Investment Pte. Ltd. As a result, we now own 38.8%, and NXP owns 61.2% of SSMC. While we, together with NXP, have the right to purchase up to 100% of
SSMCs annual capacity, we and NXP are required to purchase, in the aggregate, at least 70% of SSMCs full capacity; we, alone, are required to purchase up to 28% of the annual installed capacity. As of February 29, 2012, we owned
approximately 38.8% of the equity interest in SSMC. See below for a detailed discussion of the contract terms we entered into with SSMC.

##### Table of Contents

We entered into a technology cooperation agreement with SSMC effective March 30, 1999
in which SSMC agreed to base at least a major part of its production activities on processes compatible to those in use in our MOS integrated circuits wafer volume production fabs. In return, we have agreed to provide SSMC with access to and benefit
of the technical knowledge and experience relating to certain processes in use in our MOS integrated circuits wafer volume production fabs and to assist SSMC by rendering certain technical services in connection with its production activities. In
addition, we granted to SSMC limited licenses of related intellectual property rights owned or controlled by us for the purpose of MOS integrated circuit production for the sole use in manufacturing products for us. SSMC pays to us during, and up to
three years after, the term of this agreement a remuneration of a fixed percentage of the net selling price of all products manufactured by SSMC. In 2009, 2010 and 2011, we had total purchases of NT$3,538 million, NT$4,521 million and NT$3,949
million (US$130 million) from SSMC, representing 2.1%, 2.1% and 1.7% of our total cost of sales, respectively.

VisEra
Technologies Company, Ltd.

In October 2003, we and OmniVision Technologies, Inc. (OVT) entered into a
shareholders agreement (the VisEra Agreement) to form VisEra Technologies Company, Ltd. (VisEra), a joint venture in Taiwan, for the purpose of providing back-end manufacturing services. In connection with the formation
of VisEra, we and OVT each entered into separate nonexclusive license agreements with VisEra pursuant to which each party licenses certain intellectual property to VisEra relating to the manufacturing services. As of February 29, 2012, we owned
a 43.2% equity interest in VisEra Technologies Company Ltd. through VisEra Cayman.

In August 2005, we entered into the first
amendment to the VisEra Agreement (the Amended VisEra Agreement) with OVT, VisEra, and VisEra Cayman, pursuant to which VisEra became a subsidiary of VisEra Cayman. In accordance with the Amended VisEra Agreement, VisEra purchased color
filter processing equipment and related assets from us for an aggregate price equivalent to US$16 million. In January 2007, we signed the second amendment and agreed to an expansion in VisEras manufacturing capacity. For the capacity
expansion, we and OVT each agreed to make an additional US$27 million investment to VisEra. There were no significant sales to or purchases from VisEra from 2009 to 2011.

Global Unichip Corporation (GUC)

In January 2003, we
acquired 52.0% equity interest in GUC, a System-on-Chip (SoC) design service company that provides large scale SoC implementation services. GUC has been listed on the Taiwan Stock Exchange since November 3, 2006. Since July 2011, we are no
longer deemed to be a controlling entity of GUC and its subsidiaries due to the termination of a Shareholders Agreement. As a result, we no longer consolidate GUC and its subsidiaries in our financial statements. As of February 29, 2012,
we owned approximately 34.8% of the equity interest in GUC.

In the second half of 2011, we had total sales of NT$2,461
million (US$81 million) to GUC, representing 0.6% of our total sales.

Legal Proceedings

As
is the case with many companies in the semiconductor industry, we have received from time to time communications from third parties asserting that our technologies, manufacturing processes, the design of the integrated circuits made by us or the use
by our customers of semiconductors made by us may infringe upon patents or other intellectual property rights of others. In some instances, these disputes have resulted in litigation by or against us and certain settlement payments by us in some
cases. Irrespective of the validity of these claims, we could incur significant costs in the defense thereof or could suffer adverse effects on our operations.

In June 2010, Keranos, LLC. filed a lawsuit in the U.S. District Court for the Eastern District of Texas alleging that TSMC, TSMC North America, and several other leading technology companies infringe
three expired U.S. patents. In response, TSMC, TSMC North America, and several co-defendants in the Texas case filed a lawsuit against Keranos in the U.S. District Court for the Northern District of California in November 2010, seeking a judgment
declaring that they did not infringe the asserted patents, and that those patents are invalid. These two litigations have been consolidated into a single case in the U.S. District Court for the Eastern District of Texas. The outcome cannot be
determined at this stage.

In December 2010, Ziptronix, Inc. filed a complaint in the U.S. District Court for the
Northern District of California accusing TSMC, TSMC North America and one other company of infringing six U.S. patents. This litigation is in its very early stages and, therefore, its outcome cannot be determined at this time.

Other than the matters described above, we were not involved in any other material litigation in 2011 and are not currently involved in
any material litigation.

Dividends and Dividend Policy

|(1) | 40% of the stock dividends were paid out of retained earnings and 60% were from capitalization of capital surplus.
|--- | ------------------------------------------------------------------------------------------------------------------

Our dividend policy is set forth in our articles of incorporation. Except as otherwise specified in the articles of incorporation or
under Taiwan law, we will not pay dividends when there is no profit or retained earnings. Our profits may be distributed by way of cash dividend, stock dividend, or a combination of cash and stock. On December 21, 2004, our shareholders
approved amendments to our articles of incorporations pursuant to which distributions of profits shall be made preferably by way of cash dividend. In addition, pursuant to the amendments, the ratio for stock dividends shall not exceed 50% of the
total distribution.

Holders of outstanding common shares on a dividend record date will be entitled to the full dividend
declared without regard to any subsequent transfer of the common shares. Payment of dividends (including in cash and in common shares) in respect of the prior year is made following approval by our shareholders at the annual general meeting of
shareholders. Distribution of stock dividends is subject to approval by the R.O.C. Financial Supervisory Commission.

Except
as otherwise specified in the articles of incorporation or under Taiwan law, we are not permitted to distribute dividends or make other distributions to shareholders in respect of any year in which we have no current or retained earnings (excluding
reserves). The R.O.C. Company Law also requires that 10% of annual net income (less prior years losses and outstanding taxes) be set aside as legal reserves until the accumulated legal reserves equal our paid-in capital. Our articles of
incorporation provide that at least one percent of annual net earnings (after recovering any losses incurred in prior years and deducting the legal reserve and special reserve provisions, if any) be distributed as a bonus to employees and that not
more than 0.3 percent of our annual net earnings (after recovering any losses incurred in prior years and deducting the legal reserve and special reserve provisions, if any) may be distributed as a bonus to directors. Under our articles of
incorporation, directors who also serve as executive officers are not entitled to any director bonuses.

Holders of ADRs
evidencing ADSs are entitled to receive dividends, subject to the terms of the deposit agreement, to the same extent as the holders of common shares. Cash dividends will be paid to the depositary in NT dollars and, after deduction of any applicable
R.O.C. taxes and except as otherwise provided in the deposit agreement, will be converted by the depositary into U.S. dollars and paid to holders. Stock dividends will be distributed to the depositary and, except as otherwise provided in the deposit
agreement, will be distributed to holders by the depositary in the form of additional ADSs.

|ITEM 10. | ADDITIONAL INFORMATION
|-------- | ----------------------

Description
of Common Shares

We are organized under the laws of the R.O.C. Set forth below is a description of our common shares,
including summaries of the material provisions of our articles of incorporation, the R.O.C. Company Law, the R.O.C. Securities and Exchange Law and the regulations promulgated thereunder.

General

Our authorized share capital is NT$280,500,000,000, divided into 28,050,000,000 common shares of which 500,000,000 common shares are reserved for the issuance for our employee stock options and among
which 25,916,222,575 common shares were issued and outstanding as of December 31, 2011.

The R.O.C. Company Law, the
R.O.C. Act for Establishment and Administration of Science Parks and the R.O.C. Securities and Exchange Law provide that any change in the issued share capital of a public company, such as us, requires the approval of its board of directors, (or,
for capital reduction, a resolution of its shareholders meeting), an amendment to its articles of incorporation (if such change also involves a change in the authorized share capital) and the approval of, or the registration with, the R.O.C.
Financial Supervisory Commission and the Ministry of Economic Affairs or the Science Park Administration (as applicable).

There are no provisions under either R.O.C. law or the deposit agreement under which holders of ADSs would be required to forfeit the
common shares represented by ADSs.

Dividends and Distributions

An R.O.C. company is generally not permitted to distribute dividends or to make any other distributions to shareholders in respect of any
year for which it did not have either earnings or retained earnings (excluding reserves). In addition, before distributing a dividend to shareholders following the end of a fiscal year, the company must recover any past losses, pay all outstanding
taxes and set aside in a legal reserve, until such time as its legal reserve equals its paid-in capital, 10% of its net income for that fiscal year (less any past losses and outstanding tax), and may set aside a special reserve. Our articles of
incorporation provide that at least one percent of the net distributable income for that fiscal year be distributed as a bonus to employees and that not more than 0.3 percent of the net distributable income for that fiscal year may be distributed as
a bonus to directors. Under our articles of incorporation, directors who also serve as executive officers are not entitled to any director bonuses. Prior to 2004, it has been our practice in each of the past years to pay all of employee bonuses in
the form of stock. In 2004, we paid 20% of the bonus in the form of cash, and in 2005, 2006, 2007, 2008 and 2009, we paid 50% of the bonus in the form of cash. In 2010 and 2011, we paid 100% of the bonus in the form of cash. Effective in 2008, both
bonus to directors and employees became expense items under the companys income statements. In 2009, half of the employee profit sharing was paid in stock, for which, the number of shares was determined based on the closing price of TSMC
common shares the day before TSMCs annual shareholders meeting. Subject to compliance with these requirements, a company may pay dividends or make other distributions from its accumulated earnings or reserves as permitted by the R.O.C.
Company Law as set forth below.

At the annual general meeting of our shareholders, the board of directors submits to the
shareholders for their approval our financial statements for the preceding fiscal year and any proposal for the distribution of a dividend or the making of any other distribution to shareholders from our earnings or retained earnings (subject to
compliance with the requirements described above) at the end of 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 thereof, as determined by the shareholders at the meeting.

In addition to permitting dividends to be paid out of earnings or retained earnings, the R.O.C. Company Law permits us to make distributions to our shareholders in cash or in the form of common shares
from capital surplus and the legal reserve. However, dividend distribution out of our legal reserve can only be effected when the accumulated legal reserve exceeds 25% of our paid-in capital.

For information as to R.O.C. taxes on dividends and distributions, see  Taxation  R.O.C. Taxation.

Preemptive Rights and Issues of Additional Common Shares

Under the R.O.C. Company Law, when a public company such as us issues new shares of common stock for cash, 10% to 15% of the issue must
be offered to its employees. The remaining new shares must be offered to existing shareholders in a preemptive rights offering, subject to a requirement under the R.O.C. Securities and Exchange Law that at least 10% of these issuances must be
offered to the public. This percentage can be increased by a resolution passed at a shareholders meeting, thereby limiting or waiving the preemptive rights of existing shareholders. The preemptive rights provisions do not apply to:



| |  |  | offerings by shareholders of outstanding shares; and
| | - |  | ----------------------------------------------------



| |  |  | offerings of new shares through a private placement approved at a shareholders meeting.
| | - |  | ----------------------------------------------------------------------------------------

Authorized but unissued shares of any class may be issued at such times and, subject to the above-mentioned provisions of the R.O.C.
Company Law and the R.O.C. Securities and Exchange Law, upon such terms as the board of directors may determine. The shares with respect to which preemptive rights have been waived may be freely offered, subject to compliance with applicable R.O.C.
law.

Meetings of Shareholders

Meetings of our shareholders may be general meetings or special meetings. General meetings of shareholders are generally held in Hsinchu, Taiwan, within six months after the end of each fiscal year.
Special meetings of shareholders may be convened by resolution of the board of directors whenever it deems necessary, or under certain circumstances, by shareholders or the audit committee. For a public company such as us, notice in writing of
shareholders meetings, stating the place, time and purpose thereof, must be sent to each shareholder at least thirty days (in the case of general meetings) and fifteen days (in the case of special meetings) prior to the date set for each
meeting.

Voting Rights

A holder of common shares has one vote for each common share. Except as otherwise provided by law, a resolution may be adopted by the holders of a simple majority of the total issued and outstanding
common shares represented at a shareholders meeting at which a majority of the holders of the total issued and outstanding common shares are present. The election of directors at a shareholders meeting is by cumulative voting. Directors
are nominated by our shareholders on the shareholders meeting at which ballots for these elections are cast. Moreover, as authorized under the R.O.C. Company Law, we have adopted a nomination procedure for election of our independent directors
in our articles of incorporation. According to our articles of incorporation, ballots for the election of directors and independent directors are cast separately.

The R.O.C. Company Law also provides that in order to approve certain major corporate actions, including (i) any amendment to the articles of incorporation (which is required for, among other
actions, any increase in authorized share capital), (ii) execution, modification or termination of any contracts regarding leasing of all business or joint operations or mandate of the companys business to other persons, (iii) the
dissolution, amalgamation or spin-off of a company or the transfer of the whole or an important part of its business or its properties or the taking over of the whole of the business or properties of any other company which would have a significant
impact on the acquiring companys operations or (iv) the removal of directors or supervisors or the distribution of any stock dividend, a meeting of the shareholders must be convened with a quorum of holders of at least two-thirds of all
issued and outstanding shares of common stock at which the holders of at least a majority of the common stock represented at the meeting vote in favor thereof. However, in the case of a publicly held company such as us, such a resolution may be
adopted by the holders of at least two-thirds of the shares of common stock represented at a meeting of shareholders at which holders of at least a majority of the issued and outstanding shares of common stock are present.

A shareholder may be represented at a shareholders meeting by proxy. A valid proxy must be delivered to us at least five days prior
to the commencement of the shareholders meeting.

Holders of ADSs will not have the right to exercise voting rights with
respect to the common shares represented thereby, except as described in  Voting of Deposited Securities.

Other Rights of Shareholders

Under the R.O.C. Company Law, dissenting shareholders are entitled to appraisal rights in the event of amalgamation, spin-off or certain
other major corporate actions. A dissenting shareholder may request us to redeem all of the shares owned by that shareholder at a fair price to be determined by mutual agreement or a court order if agreement cannot be reached. A shareholder may
exercise these appraisal rights by serving written notice on us prior to the related shareholders meeting and by raising an objection at the shareholders meeting. In addition to appraisal rights, any shareholder has the right to sue for
the annulment of any resolution adopted at a shareholders meeting where the procedures were legally defective within thirty days after the date of such shareholders meeting. One or more shareholders who have held more than three percent
of the issued and outstanding shares for over a year may require audit committee to bring a derivative action against a director for that directors liability to us as a result of that directors unlawful actions or failure to act. In
addition, one or more shareholders who have held more than three percent of our issued and outstanding shares for over a year may require the board of directors to convene a special shareholders meeting by sending a written request to the
board of directors.

The R.O.C. Company Law has been amended to allow shareholder(s) holding 1% or more of the total issued
shares of a company to, during the period of time prescribed by the company, submit one proposal in writing containing no more than three hundred words (Chinese characters) for discussion at the general meeting of shareholders. In addition, if a
company adopts a nomination procedure for election of directors or supervisors in its articles of incorporation, shareholders representing 1% or more of the total issued shares of such company may submit a candidate list in writing to the company
along with relevant information and supporting documents.

Register of Shareholders and Record Dates

Our share registrar, Chinatrust Commercial Bank, maintains the register of our shareholders at its office in Taipei, Taiwan, and enters
transfers of the common shares in the register upon presentation of, among other documents, the certificates in respect of the common shares transferred. Under the R.O.C. Company Law, the transfer of common shares in registered form is effected by
endorsement of the transferors and transferees seals on the share certificates and delivery of the related share certificates. In order to assert shareholders rights against us, however, the transferee must have his name and
address registered on the register of shareholders. Shareholders are required to file their respective specimen signatures or seals with us. The settlement of trading in the common shares is carried out on the book-entry system maintained by the
Taiwan Depository & Clearing Corporation.

The R.O.C. Company Law permits us to set a record date and close the
register of shareholders for a specified period in order for us to determine the shareholders or pledgees that are entitled to certain rights pertaining to common shares by giving advance public notice. Under the R.O.C. Company Law, our register of
shareholders should be closed for a period of sixty days, thirty days and five days immediately before each general meeting of shareholders, special meeting of shareholders and record date of dividend distribution, respectively.

Annual Financial Statements

Under the R.O.C. Company Law, ten days before the general meeting of shareholders, our annual financial statements must be available at our principal office in Hsinchu for inspection by the shareholders.

Acquisition of Common Shares by Us

With minor exceptions, we may not acquire our common shares under the R.O.C. Company Law. However, under the R.O.C. Securities and Exchange Law, we may, by a board resolution adopted by majority consent
at a meeting with two-thirds of our directors present, purchase our common shares on the Taiwan Stock Exchange or by a tender offer, in accordance with the procedures prescribed by the R.O.C. Financial Supervisory Commission, for the following
purposes: (i) to transfer shares to our employees; (ii) to satisfy our obligations to provide our common shares upon exercise or conversion of any warrants, convertible bonds or convertible preferred shares; and (iii) if necessary, to
maintain our credit and our shareholders equity (such as for the purpose of supporting the trading price of our common shares during market dislocations), provided that the common shares so purchased shall be cancelled thereafter.

We are not allowed to purchase more than ten percent of our total issued and outstanding common shares. In addition, we may not spend
more than the aggregate amount of our retained earnings, premium from issuing stock and the realized portion of the capital reserve to purchase our common shares.

##### Table of Contents

We may not pledge or hypothecate any purchased common shares. In addition, we may not
exercise any shareholders rights attached to such common shares. In the event that we purchase our common shares on the Taiwan Stock Exchange, our affiliates, directors, managers and their respective spouses, minor children and nominees are
prohibited from selling any of our common shares during the period in which we purchase our common shares.

In addition,
effective from November 14, 2001 under the revised R.O.C. Company Law, our subsidiaries may not acquire our shares. This restriction does not, however, affect any of our shares acquired by our subsidiaries prior to November 14, 2001.

Liquidation Rights

In the event of our liquidation, the assets remaining after payment of all debts, liquidation expenses, taxes and distributions to holders of preferred shares, if any, will be distributed pro rata to our
shareholders in accordance with the R.O.C. Company Law.

Transaction Restrictions

The R.O.C. Securities and Exchange Law (i) requires each director, supervisor, manager or shareholder holding more than ten percent
of the shares of a public company to report the amount of that persons shareholding to that company and (ii) limits the number of shares that can be sold or transferred on the Taiwan Stock Exchange or on the Over-the-Counter (GreTai)
Securities Market by that person per day.

Material Contracts

On November 9, 2009, we settled our action brought in the California State Court against Semiconductor Manufacturing International Corporation (SMIC) in 2006 related to SMICs
misappropriation of TSMCs trade secrets and its breach of the 2005 settlement agreement between the two companies. Pursuant to the new settlement agreement, the parties entered a stipulated judgment in favor of TSMC in the California action
and the dismissal of the SMIC appeal against the Beijing Higher Courts finding in favor of TSMC. The new settlement agreement and the stipulated judgment also require SMIC to: (a) make cash payments to TSMC totaling US$200 million, which
are in addition to the US$135 million previously paid to TSMC under the 2005 settlement agreement; and (b) conditional upon relevant government regulatory approvals, to issue to TSMC a total of 1,789,493,218 common shares of SMIC (representing
about 8% of SMICs total shares outstanding as of December 31, 2009) and a three-year warrant to purchase 695,914,030 SMIC common shares (subject to adjustment) at HK$1.30 per share (subject to adjustment). Both parties also agreed to
terminate the patent cross-licensing agreement signed in 2005. On July 5, 2010, we acquired the above mentioned common shares.

Foreign Investment in the R.O.C.

Historically, foreign investment in the R.O.C. securities market has been restricted. Since 1983, the R.O.C. government has periodically enacted legislation and adopted regulations to permit foreign
investment in the R.O.C. securities market.

On September 30, 2003, the Executive Yuan approved an amendment to
Regulations Governing Investment in Securities by Overseas Chinese and Foreign National, or the Regulations, which took effect on October 2, 2003. According to the Regulations, the R.O.C. Financial Supervisory Commission abolished the mechanism
of the so-called qualified foreign institutional investors and general foreign investors as stipulated in the Regulations before the amendment.

Under the Regulations, foreign investors are classified as either onshore foreign investors or offshore foreign investors according to their respective geographical location. Both
onshore and offshore foreign investors are allowed to invest in R.O.C. securities after they register with the Taiwan Stock Exchange. The Regulations further classify foreign investors into foreign institutional investors and foreign individual
investors. Foreign institutional investors refer to those investors incorporated and registered in accordance with foreign laws outside of the R.O.C. (i.e., offshore foreign institutional investors) or their branches set up and
recognized within the R.O.C. (i.e., onshore foreign institutional investors). Offshore overseas Chinese and foreign individual investors may be subject to a maximum investment ceiling that will be separately determined by the R.O.C. Financial
Supervisory Commission after consultation with the Central Bank of the Republic of China (Taiwan). Currently, there is no maximum investment ceiling for offshore overseas Chinese and foreign individual investors. On the other hand, foreign
institutional investors are not subject to any ceiling for investment in the R.O.C. securities market.

##### Table of Contents

Except for certain specified industries, such as telecommunications, investments in
R.O.C.-listed companies by foreign investors are not subject to individual or aggregate foreign ownership limits. Custodians for foreign investors are required to submit to the Central Bank of the Republic of China (Taiwan) and the Taiwan Stock
Exchange a monthly report of trading activities and status of assets under custody and other matters. Capital remitted to the R.O.C. under these guidelines may be remitted out of the R.O.C. at any time after the date the capital is remitted to the
R.O.C. Capital gains and income on investments may be remitted out of the R.O.C. at any time.

Foreign investors (other than
foreign investors who have registered with the Taiwan Stock Exchange for making investments in the R.O.C. securities market) who wish to make direct investments in the shares of R.O.C. companies are required to submit a foreign investment approval
application to the Investment Commission of the R.O.C. Ministry of Economic Affairs or other applicable government authority. The Investment Commission or such other government authority reviews each foreign investment approval application and
approves or disapproves each application after consultation with other governmental agencies (such as the Central Bank of the Republic of China (Taiwan) and the R.O.C. Financial Supervisory Commission).

Under current R.O.C. law, any non-R.O.C. person possessing a foreign investment approval may repatriate annual net profits, interest and
cash dividends attributable to the approved investment. Stock dividends attributable to this investment, investment capital and capital gains attributable to this investment may be repatriated by the non-R.O.C. person possessing a foreign investment
approval after approvals of the Investment Commission or other government authorities have been obtained.

In addition to the
general restriction against direct investment by non-R.O.C. persons in securities of R.O.C. companies, non-R.O.C. persons (except in certain limited cases) are currently prohibited from investing in certain industries in the R.O.C. pursuant to a
negative list, as amended by the Executive Yuan. The prohibition on foreign investment in the prohibited industries specified in the negative list is absolute in the absence of a specific exemption from the application of the negative
list. Pursuant to the negative list, certain other industries are restricted so that non-R.O.C. persons (except in limited cases) may invest in these industries only up to a specified level and with the specific approval of the relevant competent
authority that is responsible for enforcing the relevant legislation that the negative list is intended to implement.

The
R.O.C. Financial Supervisory Commission announced on April 30, 2009 the Regulations Governing Mainland Chinese Investors Securities Investments (PRC Regulations). According to the PRC Regulations, a PRC qualified domestic
institutional investor (QDII) is allowed to invest in R.O.C. securities (including up to 10% shareholding of an R.O.C. company listed on Taiwan Stock Exchange or Over-the-Counter (GreTai) Securities Market). Nevertheless, the total
investment amount of QDIIs cannot exceed US$500 million. For each QDII, the custodians of such QDIIs must apply with the Taiwan Stock Exchange for the remittance amount for each QDII, which cannot exceed US$100 million, and QDII can only invest in
the ROC securities market with the amount approved by the Taiwan Stock Exchange. In addition, QDIIs are currently prohibited from investing in certain industries, and their investment of certain other industries in a given company is restricted to a
certain percentage pursuant to a list promulgated by the FSC and amended from time to time. PRC investors other than QDII are prohibited from making investments in an R.O.C. company listed on the Taiwan Stock Exchange or the Over-the-Counter
(GreTai) Securities Market if the investment is less than 10% of the equity interest of such R.O.C. company.

In addition to
investments permitted under the PRC Regulations, PRC investors who wish to make (i) direct investment in the shares of ROC private companies or (ii) investments, individually or aggregately, in 10% or more of the equity interest of an ROC
company listed on the Taiwan Stock Exchange or Over-the-Counter (GreTai) Securities Market are required to submit an investment approval application to the Investment Commission of the Ministry of Economic Affairs or other government authority. The
Investment Commission or such other government authority reviews Investment Approval application and approves or disapproves each application after consultation with other governmental agencies. Furthermore, PRC investor who wishes to be elected as
an R.O.C. companys director or supervisor shall also submit an investment approval application to the Investment Commission of the Ministry of Economic Affairs or other government authority for approval.

Depositary Receipts

In April 1992, the R.O.C. Financial Supervisory Commission enacted regulations permitting R.O.C. companies with securities listed on the Taiwan Stock Exchange, with the prior approval of the R.O.C.
Financial Supervisory Commission, to sponsor the issuance and sale to foreign investors of depositary receipts. Depositary receipts represent deposited shares of R.O.C. companies. In December 1994, the R.O.C. Financial Supervisory Commission allowed
companies whose shares are traded on the R.O.C. Over-the-Counter (GreTai) Securities Market or listed on the Taiwan Stock Exchange, upon approval of the R.O.C. Financial Supervisory Commission, to sponsor the issuance and sale of depositary
receipts.

Our deposit agreement has been amended and restated on November 16, 2007 to: (i) make our ADSs eligible
for the direct registration system, as required by the New York Stock Exchange, by providing that ADSs may be certificated or uncertificated securities, (ii) enable the distribution of our reports by electronic means and (iii) reflect
changes in R.O.C. laws in connection with the nomination of candidates for independent directors, for voting at the meeting of the shareholders. A copy of our amended and restated deposit agreement has been filed under the cover of Form F-6 on
November 16, 2007.

A holder of depositary receipts (other than citizens of the PRC and entities organized under the laws
of the PRC save for QDII or those which otherwise obtain the approval of the Investment Commission of the Ministry of Economic Affairs) may request the depositary to either cause the underlying shares to be sold in the R.O.C. and to distribute the
sale proceeds to the holder or to withdraw from the depositary receipt facility the shares represented by the depositary receipts to the extent permitted under the deposit agreement (for depositary receipts representing existing shares, immediately
after the issuance of the depositary receipts; and for depositary receipts representing new shares, in practice four to seven business days after the issuance of the depositary receipts) and transfer the shares to the holder.

We, or the foreign depositary bank, may not increase the number of depositary receipts by depositing shares in a depositary receipt
facility or issuing additional depositary receipts against these deposits without specific R.O.C. Financial Supervisory Commission approval, except in limited circumstances. These circumstances include issuances of additional depositary receipts in
connection with:



| |  |  | dividends or free distributions of shares;
| | - |  | ------------------------------------------



| |  |  | the exercise by holders of existing depositary receipts of their pre-emptive rights in connection with capital increases for cash; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if permitted under the deposit agreement and custody agreement, the deposit of common shares purchased by any person directly or through a depositary
bank on the Taiwan Stock Exchange or the Over-the-Counter (GreTai) Securities Market (as applicable) or held by such person for deposit in the depositary receipt facility.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

However, the total number of deposited shares outstanding after an issuance under the circumstances described in the third clause above
may not exceed the number of deposited shares previously approved by the R.O.C. Financial Supervisory Commission plus any depositary receipts created under the circumstances described in the first two clauses above. Issuances of additional
depositary receipts under the circumstances described in the third clause above will be permitted to the extent that previously issued depositary receipts have been canceled and the underlying shares have been withdrawn from the depositary receipt
facility.

Under current R.O.C. law, a non-R.O.C. holder of ADSs who withdraws and holds the underlying shares must register
with the Taiwan Stock Exchange and appoint an eligible local agent to:



| |  |  | open a securities trading account with a local securities brokerage firm;
| | - |  | -------------------------------------------------------------------------



| |  |  | remit funds; and
| | - |  | ----------------



| |  |  | exercise rights on securities and perform other matters as may be designated by the holder.
| | - |  | -------------------------------------------------------------------------------------------

Under existing R.O.C. laws and regulations, without this account, holders of ADSs that withdraw and hold the common shares represented by
the ADSs would not be able to hold or subsequently transfer the common shares, whether on the Taiwan Stock Exchange or otherwise. In addition, a withdrawing non-R.O.C. holder must appoint a local bank to act as custodian for handling confirmation
and settlement of trades, safekeeping of securities and cash proceeds and reporting of information.

##### Table of Contents

Holders of ADSs who are non-R.O.C. persons withdrawing common shares represented by ADSs are
required under current R.O.C. law and regulations to appoint an agent in the R.O.C. for filing tax returns and making tax payments. This agent, a tax guarantor, must meet certain qualifications set by the R.O.C. Ministry of Finance and,
upon appointment, becomes a guarantor of the withdrawing holders R.O.C. tax payment obligations. In addition, under current R.O.C. law, repatriation of profits by a non-R.O.C. withdrawing holder is subject to the submission of evidence of the
appointment of a tax guarantor to, and approval thereof by, the tax authority, or submission of tax clearance certificates or submission of evidencing documents issued by such agent (so long as the capital gains from securities transactions are
exempt from R.O.C. income tax).

Under existing R.O.C. laws and regulations relating to foreign exchange control, a depositary
may, without obtaining further approvals from the Central Bank of the Republic of China (Taiwan) or any other governmental authority or agency of the R.O.C., convert NT dollars into other currencies, including U.S. dollars, in respect of the
following: proceeds of the sale of shares represented by depositary receipts, proceeds of the sale of shares received as stock dividends and deposited into the depositary receipt facility and any cash dividends or cash distributions received. In
addition, a depositary, also without any of these approvals, may convert inward remittances of payments into NT dollars for purchases of underlying shares for deposit into the depositary receipt facility against the creation of additional depositary
receipts. A 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 other currencies relating to the sale of
subscription rights for new shares. Proceeds from the sale of any underlying shares by holders of depositary receipts withdrawn from the depositary receipt facility may be converted into other currencies without obtaining Central Bank of the
Republic of China (Taiwan) approval. Proceeds from the sale of the underlying shares withdrawn from the depositary receipt facility may be used for reinvestment in the Taiwan Stock Exchange or the Over-the-Counter (GreTai) Securities Market, subject
to compliance with applicable laws and regulations.

Direct Share Offerings

Since 1997, the R.O.C. government has amended regulations to permit R.O.C. companies listed on the Taiwan Stock Exchange or
Over-the-Counter (GreTai) Securities Market to issue shares directly (not through depositary receipt facility) overseas.

Overseas Corporate Bonds

Since 1989, the R.O.C. Financial Supervisory Commission has approved a series of overseas bonds issued by R.O.C. companies listed on the Taiwan Stock Exchange or the Over-the-Counter (GreTai) Securities
Market in offerings outside the R.O.C. Under current R.O.C. law, these overseas corporate bonds can be:



| |  |  | converted by bondholders, other than citizens of the PRC and entities organized under the laws of the PRC save for QDII or those that have obtained the
approval of the Investment Commission of the Ministry of Economic Affairs, into shares of R.O.C. companies; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | subject to R.O.C. Financial Supervisory Commission approval, converted into depositary receipts issued by the same R.O.C. company or by the issuing
company of the exchange shares, in the case of exchangeable bonds.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The relevant regulations also permit
public issuing companies to issue corporate debt in offerings outside the R.O.C. Proceeds from the sale of the shares converted from overseas convertible bonds may be used for reinvestment in securities listed on the Taiwan Stock Exchange or traded
on the Over-the-Counter (GreTai) Securities Market, subject to compliance with applicable laws and regulations.

Exchange Controls in the
R.O.C.

The Foreign Exchange Control Statute and regulations provide that all foreign exchange transactions must be
executed by banks designated to handle such business by the R.O.C. Financial Supervisory Commission and by the Central Bank of the Republic of China (Taiwan). 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, and all foreign currency needed for the importation of merchandise and services may be purchased freely from the designated foreign
exchange banks.

##### Table of Contents

Trade aside, R.O.C. companies and resident individuals may, without foreign exchange
approval, remit to and from the R.O.C. foreign currency of up to US$50 million (or its equivalent) and US$5 million (or its equivalent), respectively, in each calendar year. Furthermore, any remittance of foreign currency into the R.O.C. by a R.O.C.
company or resident individual in a year will be offset by the amount remitted out of R.O.C. by such company or individual (as applicable) within its annual quota and will not use up its annual inward remittance quota to the extent of such offset.
The above limits apply to remittances involving a conversion of NT dollars to a foreign currency and vice versa. A requirement is also imposed on all enterprises to register medium- and long-term foreign debt with the Central Bank of the Republic of
China (Taiwan).

In addition, foreign persons may, subject to certain requirements, but without foreign exchange approval of
the Central Bank of the Republic of China (Taiwan), remit outside and into the R.O.C. foreign currencies of up to US$100,000 (or its equivalent) for each remittance. The above limit applies to remittances involving a conversion of NT dollars to a
foreign currency and vice versa. The above limit does not, however, apply to the conversion of NT dollars into other currencies, including U.S. dollars, in respect of the proceeds of sale of any underlying shares withdrawn from a depositary receipt
facility.

Voting of Deposited Securities

Holders may direct the exercise of voting rights with respect to the common shares represented by the ADSs only in accordance with the provisions of the deposit agreement as described below and applicable
R.O.C. law. See Item 3. Key Information  Risk Factors  Risks Relating to Ownership of ADSs  Your voting rights as a holder of ADSs will be limited.

Except as described below, the holders will not be able to exercise the voting rights attaching to the common shares represented by the
ADSs on an individual basis. According to provisions of the deposit agreement, the voting rights attaching to the common shares represented by ADSs must be exercised as to all matters subject to a vote of shareholders by the depositary bank or its
nominee, who represents all holders of ADSs, collectively in the same manner, except in the case of an election of directors. Directors are elected by cumulative voting unless our articles of incorporation stipulate otherwise.

In the deposit agreement, the holders will appoint the depositary bank as their representative to exercise the voting rights with respect
to the common shares represented by the ADSs.

We will provide the depositary bank with copies (including English
translations) of notices of meetings of our shareholders and the agenda of these meetings, including an indication of the number of directors to be elected if an election of directors is to be held at the meeting. The depositary bank has agreed to
request and we will, therefore, also provide a list of the candidates who have expressed their intention to run for an election of directors. The depositary bank will mail these materials, together with a voting instruction form to holders as soon
as practicable after the depositary bank receives the materials from us. In order to validly exercise its voting rights, the holder of ADSs must complete, sign and return to the depositary bank the voting instruction form by a date specified by the
depositary bank. Additional or different candidates may be nominated at the meeting of the shareholders other than those proposed in the list provided by us and after the depositary bank has mailed the voting instruction form to the holders. If such
change were to occur, the depositary bank may calculate the votes according to procedures not inconsistent with the provisions of the deposit agreement, but shall not exercise any discretion regarding the holders voting rights and if the
depositary bank elects to develop such procedures, it has agreed to do so in a manner so as to give effect, to the extent practicable, to the instructions received from the holders.

Subject to the provisions described in the second succeeding paragraph, which will apply to the election of directors done by means of
cumulative voting, if persons together holding at least 51% of the ADSs outstanding at the relevant record date instruct the depositary bank to vote in the same manner in respect of one or more resolutions to be proposed at the meeting (other than
the election of directors), the depositary bank will notify the instructions to the chairman of our board of directors or a person he may designate. The depositary bank will appoint the chairman or his designated person to serve as the voting
representative of the depositary bank or its nominee and the holders. The voting representative will attend such meeting and vote all the common shares represented by ADSs to be voted in the manner so instructed by such holders in relation to such
resolution or resolutions.

##### Table of Contents

If, for any reason, the depositary bank has not by the date specified by it received
instructions from persons together holding at least 51% of all the ADSs outstanding at the relevant record date to vote in the same manner in respect of any resolution specified in the agenda for the meeting (other than the election of directors),
then the holders will be deemed to have instructed the depositary bank or its nominee to authorize and appoint the voting representative as the representative of the depositary bank and the holders to attend such meeting and vote all the common
shares represented by all ADSs as the voting representative deems appropriate with respect to such resolution or resolutions, which may not be in your interests; provided, however, that the depositary bank or its nominee will not give any such
authorization and appointment unless it has received an opinion of R.O.C. counsel addressed to the depositary bank and in form and substance satisfactory to the depositary bank, at its sole expense, to the effect that, under R.O.C. law (i) the
deposit agreement is valid, binding and enforceable against us and the holders and (ii) the depositary bank will not be deemed to be authorized to exercise any discretion when voting in accordance with the deposit agreement and will not be
subject to any potential liability for losses arising from such voting. We and the depositary bank will take such actions, including amendment of the provisions of the deposit agreement relating to voting of common shares, as we deem appropriate to
endeavor to provide for the exercise of voting rights attached to the common shares represented by all ADSs at shareholders meetings in a manner consistent with applicable R.O.C. law.

The depositary bank will notify the voting representative of the instructions for the election of directors received from holders and
appoint the voting representative as the representative of the depositary bank and the holders to attend such meeting and vote the common shares represented by ADSs as to which the depositary bank has received instructions from holders for the
election of directors, subject to any restrictions imposed by R.O.C. law and our articles of incorporation. Holders who by the date specified by the depositary bank have not delivered instructions to the depositary bank will be deemed to have
instructed the depositary bank to authorize and appoint the voting representative as the representative of the depositary bank or its nominee and the holders to attend such meeting and vote all the common shares represented by ADSs as to which the
depositary bank has not received instructions from the holders for the election of directors as the voting representative deems appropriate, which may not be in your best interests. Candidates standing for election as representatives of a
shareholder may be replaced by such shareholder prior to the meeting of the shareholders, and the votes cast by the holders for such candidates shall be counted as votes for their replacements.

By accepting and continuing to hold ADSs or any interest therein, the holders will be deemed to have agreed to the voting provisions set
forth in the deposit agreement, as such provisions may be amended from time to time to comply with applicable R.O.C. law.

There can be no assurance that the holders will receive notice of shareholders meetings sufficiently prior to the date established
by the depositary bank for receipt of instructions to enable you to give voting instructions before the cutoff date.

Moreover, in accordance with the deposit agreement, as further amended and restated as of November 16, 2007 and pursuant to R.O.C.
Company Law, holders that individually or together with other holders hold at least 51% of the ADSs outstanding at the relevant record date are entitled to submit each year one written proposal for voting at the general meeting of shareholders;
provided, that (i) such proposal is in Chinese language and does not exceed 300 Chinese characters, (ii) such proposal is submitted to the depositary bank at least two business days prior to the expiry of the relevant submission period,
which shall be publicly announced by us each year in a report on Form 6-K filed with the Securities Exchange Commission prior to the commencement of the 60 days closed period for general meetings of shareholders, (iii) such proposal is
accompanied by a written certificate to the depositary bank, in the form required by the depository bank, certifying that such proposal is being submitted by holders that individually or together with other holders hold at least 51% of the ADSs
outstanding at the date of the submission and, if the date of the submission is on or after the relevant record date, also certifying that the holders who submitted the proposal held at least 51% of the ADSs outstanding as of the relevant record
date, (iv) if the date of the submission is prior to the relevant record date, the holders who submitted the proposal must also provide, within five business days after the relevant record date, a second written certificate to the depositary
bank, in the form required by the depositary bank, certifying that the holders who submitted the proposal continued to hold at least 51% of the ADSs outstanding at the relevant record date, (v) such proposal is accompanied by a joint and
several irrevocable undertaking of all submitting holders to pay all fees and expenses incurred in relation to the submission (including the costs and expenses of the depositary bank or its agent to attend the general meeting of the shareholders) as
such fees and expenses may be reasonably determined and documented by the depositary bank or us, and (vi) such proposal shall only be voted upon at the general meeting of shareholders if such proposal is accepted by our board of directors as
eligible in accordance with applicable law for consideration at a shareholders meeting.

Taxation

R.O.C. Taxation

The following is a general summary of the principal
R.O.C. tax consequences of the ownership and disposition of ADSs representing common shares to a non-resident individual or entity. It applies only to a holder that is:



| |  |  | an individual who is not an R.O.C. citizen, who owns ADSs and who is not physically present in the R.O.C. for 183 days or more during any calendar
year; or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a corporation or a non-corporate body that is organized under the laws of a jurisdiction other than the R.O.C. for profit-making purposes and has no
fixed place of business or other permanent establishment in the R.O.C.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Holders of ADSs are urged to consult
their own tax advisors as to the particular R.O.C. tax consequences of owning the ADSs which may affect them.

Dividends. Dividends declared by us out of our retained earnings and distributed to the holders are subject to R.O.C.
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% R.O.C. retained earnings tax paid by us on our
undistributed after-tax earnings, if any, would provide a credit of up to 10% of the gross amount of any dividends declared out of those earnings that would reduce the 20% R.O.C. tax imposed on those distributions.

Distribution of common shares declared by us out of our capital reserves is not subject to R.O.C. withholding tax.

Capital Gains. Under R.O.C. law, capital gains on transactions in the common shares are currently exempt from income tax.
In addition, transfers of ADSs are not regarded as a sale of an R.O.C. security and, as a result, any gains on such transactions are not subject to R.O.C. income tax.

Subscription Rights. Distributions of statutory subscription rights for common shares in compliance with R.O.C. law are not subject to any R.O.C. tax. Proceeds derived from sales of
statutory subscription rights evidenced by securities are exempted from income tax but are subject to securities transaction tax at the rate of 0.3% of the gross amount received. Proceeds derived from sales of statutory subscription rights that are
not evidenced by securities are subject to capital gains tax at the rate of 20%.

Subject to compliance with R.O.C. law, we,
at our sole discretion, can determine whether statutory subscription rights shall be evidenced by issuance of securities.

Securities Transaction Tax. A securities transaction tax, at the rate of 0.3% of the sales proceeds, will be withheld upon
a sale of common shares in the R.O.C. Transfers of ADSs are not subject to R.O.C. securities transaction tax. Withdrawal of common shares from the deposit facility is not subject to R.O.C. securities transaction tax.

Estate and Gift Tax. R.O.C. estate tax is payable on any property within the R.O.C. of a deceased who is an individual, and
R.O.C. gift tax is payable on any property within the R.O.C. donated by an individual. Estate tax and Gift tax are currently payable at the rate of 10%. Under R.O.C. estate and gift tax laws, common shares issued by R.O.C. companies are deemed
located in the R.O.C. regardless of the location of the holder. It is unclear whether a holder of ADSs will be considered to hold common shares for this purpose.

Tax Treaty. The R.O.C. does not have a double taxation treaty with the United States. On the other hand, the R.O.C. has double taxation treaties with Indonesia, Singapore, South Africa,
Australia, Vietnam, New Zealand, Malaysia, Macedonia, Israel, Gambia, The Netherlands, the United Kingdom, Senegal, Sweden, Belgium, Denmark, Paraguay, Hungary, France, Swaziland, India, Slovakia, and Switzerland which may limit the rate of R.O.C.
withholding tax on dividends paid with respect to common shares in R.O.C. companies. The ADS holders may be considered to hold common shares for the purposes of these treaties. Accordingly, if the holders may otherwise be entitled to the benefits of
the relevant income tax treaty, the holders should consult their tax advisors concerning their eligibility for the benefits with respect to the ADSs.

United States Federal Income Taxation

This section discusses the material United States federal income tax consequences to U.S. holders (as defined below) of owning and
disposing of our common shares or ADSs. It applies to you only if you hold your common shares or ADSs as capital assets for tax purposes. This section does not apply to you if you are a member of a special class of holders subject to special rules,
including:



| |  |  | dealers or traders in securities or foreign currencies;
| | - |  | -------------------------------------------------------



| |  |  | banks and certain other financial institutions;
| | - |  | -----------------------------------------------



| |  |  | brokers;
| | - |  | --------



| |  |  | traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | tax-exempt organizations, retirement plans, individual retirement accounts and other tax-deferred accounts;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | life insurance companies;
| | - |  | -------------------------



| |  |  | persons liable for alternative minimum tax;
| | - |  | -------------------------------------------



| |  |  | persons that actually or constructively own 10% or more of our voting stock;
| | - |  | ----------------------------------------------------------------------------



| |  |  | persons that hold common shares or ADSs as part of a straddle or a hedging or conversion or integrated transaction for tax purposes;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | persons who are former citizens or former long-term residents of the United States, or
| | - |  | --------------------------------------------------------------------------------------



| |  |  | persons whose functional currency is not the U.S. dollar.
| | - |  | ---------------------------------------------------------

This section is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations, published rulings and court decisions, all as currently in effect. These
laws are subject to change, possibly on a retroactive basis. In addition, this section is based in part upon the representations of the depositary and the assumption that each obligation in the Deposit Agreement and any related agreement will be
performed in accordance with its terms. In general, for United States federal income tax purposes, if you hold ADRs evidencing ADSs, you will be treated as the owner of the shares represented by those ADSs. Exchanges of shares for ADRs, and ADRs for
shares, generally will not be subject to United States federal income tax.

Further, this section is based on the
depositarys representation that it will not, by reason of existing Taiwanese legal and regulatory limitations applicable to depositary receipt programs, engage in the issuance of ADRs prior to the receipt of shares or the release of shares
prior to the cancellation of ADRs (pre-release transactions). The depositary has not represented that it will not engage in pre-release transactions if such Taiwanese legal and regulatory limitations change. If the depositary engages in
such pre-release transactions, there may be material adverse United States federal income tax consequences to holders of ADRs.

You are a U.S. holder if you are a beneficial owner of common shares or ADSs and you are:



| |  |  | a citizen or resident of the United States;
| | - |  | -------------------------------------------

##### Table of Contents

| |  |  | a domestic corporation, or other entity subject to United States federal income tax as a domestic corporation;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | an estate whose income is subject to United States federal income tax regardless of its source; or
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | a trust if a United States court can exercise primary supervision over the trusts administration and one or more United States persons are
authorized to control all substantial decisions of the trust.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If a partnership (including for this purpose
any entity treated as a partnership for United States federal income tax purposes) is a beneficial owner of the common shares or ADSs, the United States tax treatment of a partner in the partnership generally will depend on the status of the partner
and the activities of the partnership. A holder of the common shares or ADSs that is a partnership and partners in such a partnership should consult their own tax advisors concerning the United States federal income tax consequences of purchasing,
owning and disposing of common shares or ADSs.

We urge you to consult your own tax advisor regarding the United States federal, state and
local, non-U.S. and other tax consequences of owning and disposing of common shares or ADSs in your particular circumstances.

Taxation of Dividends

Subject to the passive foreign investment
company, or PFIC, rules discussed below, if you are a U.S. holder, the gross amount of any dividend we pay in respect of your common shares or ADSs out of our current or accumulated earnings and profits (as determined for United States federal
income tax purposes) including the amount of any R.O.C. tax withheld reduced by any credit against such withholding tax on account of the 10% retained earnings tax imposed on us, is subject to United States federal income taxation. Because we do not
intend to calculate our earnings and profits under U.S. federal income tax principles, a U.S. Holder should expect that any distribution made by us to such holder will generally be treated as a dividend. If you are a noncorporate U.S. holder, under
existing law any dividends paid to you in taxable years beginning before January 1, 2013 that constitute qualified dividend income will be taxable to you at a maximum tax rate of 15% provided that you hold the common shares or ADSs for more
than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period requirements. Dividends we pay with respect to the common shares or ADSs will be qualified dividend income provided that, in the year
that you receive the dividend, the common shares or ADSs are readily tradable on an established securities market in the United States. The dividend is taxable to you when you, in the case of common shares, or the Depositary, in the case of ADSs,
receive the dividend actually or constructively. The dividend will not be eligible for the dividends-received deduction generally allowed to United States corporations in respect of dividends received from other United States corporations. The
amount of the dividend distribution that you must include in your income as a U.S. holder will be the U.S. dollar value of the NT Dollar payments made, determined at the spot NT Dollar/U.S. dollar rate on the date the dividend distribution is
includible in your income, regardless of whether the payment is in fact converted into U.S. dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date you include the dividend payment in income
to the date you convert the payment into U.S. dollars will be treated as ordinary income or loss and will not be eligible for the special tax rate applicable to qualified dividend income. The gain or loss generally will be income or loss from
sources within the United States for foreign tax credit limitation purposes. Distributions in excess of current and accumulated earnings and profits, as determined for United States federal income tax purposes, will be treated as a non-taxable
return of capital to the extent of your basis in the common shares or ADSs and thereafter as capital gain.

Subject to
generally applicable limitations and restrictions, the R.O.C. taxes withheld from dividend distributions and paid over to the R.O.C. (reduced by any credit against such withholding tax on account of the 10% retained earnings tax) will be eligible
for credit against your U.S. federal income tax liabilities. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the maximum 15% tax rate. Dividends will be income from sources outside
the United States. Dividends will, depending on your circumstances, be passive or general income which, in either case, is treated separately from other types of income for purposes of computing the foreign tax credit
allowable to you. The rules applicable to the United States foreign tax credit are complex, and we urge you to consult your own tax adviser concerning the availability of the credit in your particular circumstances.

##### Table of Contents

Pro rata distributions of common shares by us to holders of common shares or ADSs will
generally not be subject to U.S. federal income tax. Accordingly, such distributions will generally not give rise to U.S. federal income against which the R.O.C. tax imposed on such distributions may be credited. Any such R.O.C. tax will generally
only be creditable against a U.S. holders U.S. federal income tax liability with respect to general limitation income and not against passive income.

In the event that the ex-dividend date on The New York Stock Exchange or other securities exchange or market for a dividend or distribution that gives rise to R.O.C. withholding tax is after the record
date for such dividend or distribution (during which period such ADSs may trade with due bills), a purchaser of ADSs during the period from the record date to the ex-dividend date likely would not be entitled to a foreign tax credit for
R.O.C. taxes paid in respect of such ADSs even if (i) the purchaser receives the equivalent of such dividend or distribution on the relevant distribution date, and (ii) an amount equivalent to the applicable R.O.C. withholding tax is
withheld therefrom or otherwise charged to the account of such purchaser.

Taxation of Capital Gains

Subject to the PFIC rules discussed below, if you are a U.S. holder and you sell or otherwise dispose of your common shares or ADSs, you
will recognize capital gain or loss for United States federal income tax purposes equal to the difference between the U.S. dollar value of the amount that you realize and your tax basis, determined in U.S. dollars, in your common shares or ADSs.
Capital gain of a noncorporate U.S. holder that is recognized in taxable years beginning before January 1, 2013 is generally taxed under existing law at a maximum rate of 15% where the property is held more than one year. The gain or loss will
generally be income or loss from sources within the United States for foreign tax credit limitation purposes.

Medicare
Tax

For taxable years beginning after December 31, 2012, a United States person that is an individual or estate,
or a trust that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax on the lesser of (1) the United States persons net investment income for the relevant taxable year and
(2) the excess of the United States persons modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individuals
circumstances). A holders net investment income will generally include its gross dividend income and its net gains from the disposition of ADSs, unless such dividends or net gains are derived in the ordinary course of the conduct of a trade or
business (other than a trade or business that consists of certain passive or trading activities). If you are a United States person that is an individual, estate or trust, you are urged to consult your tax advisors regarding the applicability of the
Medicare tax to your income and gains in respect of your investment in the ADSs.

Passive Foreign Investment Company
Rules

We believe that common shares and ADSs should not be treated as stock of a PFIC for United States federal
income tax purposes for the current taxable year and for future taxable years, but this conclusion is a factual determination that is made annually, based on the categories and amounts of income that we earn and the categories and valuation of our
assets (including goodwill) for each taxable year, and thus may be subject to change. Accordingly, no assurance can be given that the Company will not be considered by the U.S. Internal Revenue Service to be a PFIC in the current or future years.

In general, if you are a U.S. holder, we will be a PFIC with respect to you if for any taxable year in which you held our
common shares or ADSs:



| |  |  | at least 75% of our gross income for the taxable year is passive income; or
| | - |  | ---------------------------------------------------------------------------



| |  |  | at least 50% of the value, determined on the basis of a quarterly average, of our assets is attributable to assets that produce or are held for the
production of passive income.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Passive income generally includes dividends, interest, royalties, rents
(other than certain rents and royalties derived in the active conduct of a trade or business), annuities and gains from assets that produce passive income. If a foreign corporation owns directly or indirectly at least 25% by value of the stock of
another corporation, the foreign corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation, and as receiving directly its proportionate share of the other corporations
income.

##### Table of Contents

If we are treated as a PFIC, and you are a U.S. holder that does not make a mark-to-market
election, as described below, you will be subject to special rules with respect to:



| |  |  | any gain you realize on the sale or other disposition of your common shares or ADSs; and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | any excess distribution that we make to you (generally, any distributions to you during a single taxable year that are greater than 125% of the average
annual distributions received by you in respect of the common shares or ADSs during the three preceding taxable years or, if shorter, your holding period for the common shares or ADSs).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under these rules:



| |  |  | the gain or excess distribution will be allocated ratably over your holding period for the common shares or ADSs,
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to the taxable year in which you realized the gain or excess distribution will be taxed as ordinary income,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to each prior year, with certain exceptions, will be taxed at the highest tax rate in effect for that year, and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the interest charge generally applicable to underpayments of tax will be imposed in respect of the tax attributable to each such year.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

Special rules apply for calculating the amount of the foreign tax credit with respect to excess
distributions by a PFIC.

If you own common shares or ADSs in a PFIC that are treated as marketable stock, you may make a
mark-to-market election. If you make this election, you will not be subject to the PFIC rules described above. Instead, in general, you will include as ordinary income each year the excess, if any, of the fair market value of your common shares or
ADSs at the end of the taxable year over your adjusted basis in your common shares or ADSs. These amounts of ordinary income will not be eligible for the favorable tax rates applicable to qualified dividend income or long-term capital gains. You
will also be allowed to take an ordinary loss in respect of the excess, if any, of the adjusted basis of your common shares or ADSs over their fair market value at the end of the taxable year (but only to the extent of the net amount of previously
included income as a result of the mark-to-market election). Your basis in the common shares or ADSs will be adjusted to reflect any such income or loss amounts. Your gain, if any, recognized upon the sale of your common shares or ADSs will be taxed
as ordinary income.

Also, where a company that is a PFIC meets certain reporting requirements, a U.S. holder could avoid
certain adverse PFIC consequences described herein by making a qualified electing fund (QEF) election to be taxed currently on its proportionate share of the PFICs ordinary income and net capital gains. U.S. holders
will not be able to treat the Company as a QEF if the Company does not prepare the information that U.S. holders would need to make a QEF election. We do not intend to prepare or provide the information that would enable U.S. Holders to make a QEF
election.

In addition, notwithstanding any election you make with regard to the common shares or ADSs, dividends that you
receive from us will not constitute qualified dividend income to you if we are a PFIC either in the taxable year of the distribution or the preceding taxable year. Moreover, your common shares or ADSs will be treated as stock in a PFIC if we were a
PFIC at any time during your holding period in your shares or ADSs, even if we are not currently a PFIC. For purposes of this rule, if you make a mark-to-market election with respect to your shares or ADSs, you will be treated as having a new
holding period in your shares or ADSs beginning on the first day of the first taxable year beginning after the last taxable year for which the mark-to-market election applies. Dividends that you receive that do not constitute qualified dividend
income are not eligible for taxation at the 15% maximum rate applicable to qualified dividend income. Instead, you must include the gross amount of any such dividend paid by us out of our accumulated earnings and profits (as determined for United
States federal income tax purposes) in your gross income, and it will be subject to tax at rates applicable to ordinary income as well as the special rules provided with respect to excess distributions, if applicable, as described above.

##### Table of Contents

If you own common shares or ADSs during any year that we are a PFIC with respect to you, you
must file Internal Revenue Service Form 8621.

The rules dealing with PFICs and with the QEF and mark-to-market elections are
very complex and are affected by various factors in addition to those described above, including the Companys ownership of any non-U.S. subsidiaries. As a result, U.S. holders are urged to consult their own tax advisors concerning the PFIC
rules.

Non-U.S. Holders

Except as described in the section titled Information reporting and backup withholding below, a non-U.S. holder will not be subject to U.S. federal income or withholding tax on the payment of
dividends and the proceeds from the disposition of shares or ADSs unless: such item is effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States and, in the case of a resident of a country which has a
treaty with the United States and is eligible for the benefits of the treaty with the United States, such item is attributable to a permanent establishment or, in the case of an individual, a fixed place of business, in the United States; or the
non-U.S. holder is an individual who holds the shares or ADSs as a capital asset and is present in the United States for 183 days or more in the taxable year of the disposition, certain other conditions are met, and such non-U.S. holder does not
qualify for an exemption. If the first exception applies, the non-U.S. holder generally will be subject to U.S. federal income tax with respect to such item in the same manner as a U.S. holder unless otherwise provided in an applicable income tax
treaty; a non-U.S. holder that is a corporation for U.S. federal income tax purposes may also be subject to a branch profits tax with respect to such item at a rate of 30% (or at a reduced rate under an applicable income tax treaty). If the second
exception applies, the non-U.S. holder generally will be subject to U.S. federal income tax at a rate of 30% (or at a reduced rate under an applicable income tax treaty) on the amount by which such non-U.S. holders capital gains allocable to
U.S. sources exceed capital losses allocable to U.S. sources during the taxable year of disposition of the shares or ADSs.

Information reporting and backup withholding

U.S. holders generally are subject to information reporting requirements with respect to dividends paid on shares or ADSs and on the proceeds from the sale, exchange or disposition of shares or ADSs
unless the holder is a corporation or otherwise establishes a basis for exemption. In addition, U.S. holders are subject to back-up withholding (currently at 28%) on dividends paid on shares or ADSs, and on the sale, exchange or other disposition of
shares or ADSs, unless each such U.S. holder provides a taxpayer identification number and a duly executed IRS Form W-9 or otherwise establishes an exemption. Non-U.S. holders generally are not subject to information reporting or backup withholding
with respect to dividends, or the proceeds from the sale, exchange or other disposition of shares or ADSs, provided that each such non-U.S. holder certifies as to its foreign status on the applicable duly executed IRS Form W-8 or otherwise
establishes an exemption. Backup withholding is not an additional tax and the amount of any backup withholding will be allowed as a credit against a U.S. holders or non-U.S. holders U.S. federal income tax liability and may entitle such
holder to a refund, provided that certain required information is timely furnished to the IRS.

Information with Respect
to Foreign Financial Assets

Under recently enacted legislation, individuals that own specified foreign
financial assets with an aggregate value in excess of $50,000 in taxable years beginning after March 18, 2010 will generally be required to file an information report with respect to such assets with their tax returns. Specified
foreign financial assets include any financial accounts maintained by foreign financial institutions, as well as any of the following, but only if they are not held in accounts maintained by financial institutions: (i) stocks and
securities issued by non-U.S. persons, (ii) financial instruments and contracts held for investment that have non-U.S. issuers or counterparties and (iii) interests in foreign entities. U.S. holders that are individuals are urged to
consult their tax advisors regarding the application of this legislation to their ownership of ADSs.

Our exposure to financial market risks derives primarily from changes in interest rates and foreign exchange rates. To mitigate these risks, we utilize derivative financial instruments, the application of
which, pursuant to our internal guidelines, is for hedging purposes and not for trading or speculative purposes.

Interest Rate Risks: We are exposed to interest rate risks, primarily related to borrowings for general corporate purposes.

Foreign Currency Risk: Substantial portions of our revenues and expenses are denominated in currencies other than NT dollar. As a result, as of December 31, 2011, the majority of our
receivables and payables were denominated in currencies other than NT dollar, primarily in U.S. dollar, Euro and Japanese Yen. To protect against reductions in value and the volatility of future cash flows caused by changes in foreign exchange
rates, we utilize foreign currency denominated debts and offsetting derivatives, including currency forward contracts and cross currency swaps, to hedge our currency exposure. These hedging transactions help to reduce partially, but do not
eliminate, the impact of foreign currency exchange rate movements. Based on a sensitivity analysis performed on our financial position as of December 31, 2011, a hypothetical, unfavorable 10% movement in the levels of foreign currency exchange
rates relative to the NT dollar, after taking into account hedges and offsetting positions, would have increased our net unrealized losses by NT$384 million.

Our policy is to account for the unrealized gains or losses of these hedging contracts on a mark-to-market rate basis and to realize the gains or losses of these contracts when the contracts mature.
Effective January 1, 2006, these derivative financial instruments are required under R.O.C. Statement of Financial Accounting Standards No. 34 Financial Instruments: Recognition and Measurement to be recognized at fair market
value on the balance sheet. Please see note 26 of our consolidated financial statements for information on the net assets, liabilities and purchase commitments that have been hedged by these derivative transactions.

Other Market Risk: In addition to our interests in VIS, SSMC, VisEra, Mcube, GUC and Motech,
we have made investments in equity securities including convertible bonds issued by private companies related to semiconductor and other technology industries mostly through a number of investment funds. As of December 31, 2011, the aggregate
carrying value of these investments on our balance sheet was NT$4,315 million (US$143 million). As of December 31, 2011, approximately NT$3,666 million (US$121 million) of this amount in venture capital investments was made through InveStar
Semiconductor Development Fund, and InveStar Semiconductor Development Fund (II), our two 97.1% owned subsidiaries, Emerging Alliance Fund L.P., VentureTech Alliance Fund II, and VentureTech Alliance Fund III, our 99.5%, 98.0% and 98.9% respectively
owned subsidiaries. The carrying value of these investments in private companies and in the investment funds are subject to fluctuation based on many factors such as prevailing market conditions. Moreover, because most of the investments are
unlisted securities, the fair market value may be significantly different from our carrying value. Upon any subsequent sale of our investments, we may not be able to realize our carrying value as of December 31, 2011 or any subsequent date. As

Disclosure Controls and Procedures. Pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, an evaluation was carried
out under the supervision and with the participation of our principal executive and principal financial officers of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief
Financial Officer concluded that these disclosure controls and procedures were effective as of December 31, 2011.

Managements Annual Report on Internal Control over Financial Reporting. Management is responsible for establishing and
maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed under the supervision of our principal executive and principal financial officers to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes in accordance with R.O.C. GAAP and the required reconciliation to U.S. GAAP. Our internal control over financial
reporting includes policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets; provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with R.O.C. GAAP and the required reconciliation to U.S. GAAP, and that receipts and expenditures are being made only in accordance with authorizations of our management and
directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

As of the end of 2011, management conducted an assessment of the effectiveness of our internal control over financial reporting based on
the framework established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has determined that our internal
control over financial reporting as of December 31, 2011 is effective.

Our independent registered public accounting
firm, Deloitte & Touche, independently assessed the effectiveness of our companys internal control over financial reporting. Deloitte & Touche has issued an attestation report, which is included at the end of this

Changes in Internal Control over Financial Reporting. During 2011, no change to our
internal control over financial reporting occurred that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Attestation Report of the Independent Registered Public Accounting Firm.

REPORT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Taiwan Semiconductor Manufacturing Company Limited

We have audited the internal control over financial reporting of Taiwan Semiconductor Manufacturing Company Limited and subsidiaries (the Company) as of December 31, 2011, 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.

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, 2011, 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, 2011 of the Company and our report dated April 13, 2012 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; and ii) the convenience translation of New Taiwan dollar amounts into U.S. dollar amounts.

|ITEM 16A. | AUDIT COMMITTEE FINANCIAL EXPERT
|--------- | --------------------------------

Our Audit Committee is currently comprised of five independent directors. Since June 1, 2005, no Audit Committee member has served as audit committee financial expert. Instead, our Audit Committee
has engaged a financial expert consultant who our board of directors determined has the attributes required of an audit committee financial expert as defined under the applicable rules of the U.S. SEC issued pursuant to Section 407
of the Sarbanes-Oxley Act of 2002. In particular, our board of directors appointed Mr. J.C. Lobbezoo to serve as an independent financial expert consultant to our Audit Committee from February 14, 2006 onwards. Our board of directors
believes that the Audit Committee members along with the advisors of the Audit Committee, including the financial expert consultant, possess sufficient financial knowledge and experience.



|ITEM 16B. | CODE OF ETHICS
|--------- | --------------

We have adopted a Policy of Ethics and Business Conduct for employees, officers and directors, which also applies to our Chief Executive Officer, Chief Financial Officer, Controller, and any
other persons performing similar functions.

We will provide to any person without charge, upon request, a
copy of our Policy of Ethics and Business Conduct. Any request should be made per email to our Investor Relations Division at invest@tsmc.com.

Audit Fees. This category includes the audit of our annual financial statements and internal
control over financial reporting, review of quarterly financial statements and services that are normally provided by the independent auditors in connection with statutory and regulatory filings or engagements for those fiscal years. This category
also includes advice on audit and accounting matters that arose during, or as a result of, the audit or the review of quarterly financial statements and statutory audits required by non-U.S. jurisdictions, including statutory audits required by the
Tax Bureau of the R.O.C., Customs Bureau of the R.O.C., and Financial Supervisory Commission (R.O.C. Financial Supervisory Commission) of the R.O.C.

Audit-Related Fees. This category consists of assurance and related services by the Deloitte Entities that are reasonably related to the performance of the audit or review of our financial

All Other Fees. This category consists of professional services rendered by the Deloitte Entities for IFRS adoption.

We have not established any pre-approval policies and procedures, and, accordingly, all non-audit services need to be pre-approved by the
Audit Committee on a case-by-case basis. In its meeting of May 5, 2006, the Audit Committee agreed to delegate to the Chairman of the Audit Committee authority to pre-approve non-material unanticipated non-audit services and to report any such
actions to the Audit Committee for ratification at its next scheduled meeting. All audit and non-audit services performed by Deloitte & Touche after May 6, 2003, the effective date of revised Rule 2-01(c) (7) of Regulation S-X
entitled Audit Committee Administration of the Engagement on strengthening requirements regarding auditor independence, were pre-approved by the Audit Committee.

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

TSMCs corporate governance practices are governed by applicable Taiwan law, specifically, the Company Law and Securities Exchange
Law, and also TSMCs Articles of Incorporation. Also, because TSMC securities are registered with the U.S. Securities and Exchange Commission (U.S. SEC) and are listed on the New York Stock Exchange (NYSE), TSMC is
subject to corporate governance requirements applicable to NYSE-listed foreign private issuers.

Under Section 303A of
the NYSE Listed Company Manual, NYSE-listed non-US companies 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 NYSE Sections 303A.06, 303A.11, 303A.12(b) and 303A.12(c).

Item 16G as well as NYSE
Section 303A.11 requires that foreign private issuers disclose any significant ways in which their corporate governance practices differ from US companies under NYSE listing standards. A NYSE-listed foreign private issuer is required to provide
to its US investors, a brief, general summary of the significant differences, either: (a) on the company website in English, or (b) in its annual report distributed to its US investors. To comply with NYSE Section 303A.11, TSMC has
prepared the comparison in the table below.

The most relevant differences between TSMC corporate governance practices and
NYSE standards for listed companies are as follows:



|                                                                                                                                                                                                                                                                                                                                                                                        |  |

|NYSE Section 303A.07(c)requires each company to
have an internal audit function that provides to the management and to the audit committee ongoing assessments on the companys risk management processes and internal control system.                                                                                                                                                                                                                                                                                                                                                                 |  | Taiwan law requires public companies to establish an internal audit department. Internal
auditors are subject to strict qualification standards under Taiwan law, which require the board of directors to approve the head of a companys internal audit department. TSMCs internal audit department has substantially the same
responsibilities as provided under NYSE Section 303A.07(d).                                                                                                                                                                        
|NYSE Section 303A.08 requires each company to
give to shareholders the opportunity to vote on all equity based compensation plans and material revisions thereto with certain exceptions.                                                                                                                                                                                                                                                                                                                                                                                                              |  | Taiwan law imposes a similar requirement. TSMC currently has in place two equity based
compensation plans. First, TSMCs employee stock option plans (ESOPs) are required to be approved by the board of directors. Shareholders approval is not required if the number of options granted under the relevant ESOP does
not exceed the reservation made in TSMCs Articles of Incorporation. Otherwise, any change to such reservation in the Articles requires shareholders approval. Second, TSMCs employees profit sharing requires shareholders
approval.
|NYSE Section 303A.09 requires public companies to
adopt and disclose corporate governance guidelines, including several issues for which such reporting is mandatory, and to include such information on the companys website (which website should also include the charters of the audit committee,
the nominating committee, and the compensation committee.)                                                                                                                                                                                                                                      |  | Under Taiwan law, if a listed company has adopted corporate governance guidelines, it must
inform investors how to access such guidelines.

|NYSE Section 303A.12(a) requires the CEO, on a

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Taiwan Semiconductor Manufacturing Company Limited

We have audited the accompanying consolidated balance sheets of Taiwan Semiconductor Manufacturing Company Limited (a Republic of China corporation) and subsidiaries (the Company) as of
December 31, 2010 and 2011, and the related consolidated statements of income, changes in shareholders equity, and cash flows for each of the three years in the period ended December 31, 2011 (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 Taiwan Semiconductor
Manufacturing Company Limited and subsidiaries as of December 31, 2010 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with accounting
principles generally accepted in the Republic of China.

As discussed in Note 4 to the consolidated financial statements, on January 1,
2009, the Company adopted the newly revised Republic of China Statement of Financial Accounting Standard No. 10, Accounting for Inventories.

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.    The application of the latter would have affected the determination of net income for each of the three years in the period ended December 31, 2011 and the determination of shareholders equity and financial
position as of December 31, 2010 and 2011, to the extent summarized in Note 34.

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
in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the Companys internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission and our report dated April 13, 2012 expressed an unqualified opinion on the Companys internal control over financial reporting.

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.

The financial statements of foreign subsidiaries
are translated into New Taiwan dollars at the following exchange rates: Assets and liabilities - spot rates at year-end; shareholders equity - historical rates; income and expenses - average rates during the year.    The
resulting translation adjustments are recorded as a separate component of shareholders equity.

Use of Estimates

The preparation of consolidated financial statements in conformity with the aforementioned guidelines and principles requires management
to make reasonable assumptions and estimates of matters that are inherently uncertain.    The actual results may differ from managements estimates.

Classification of Current and Noncurrent Assets and Liabilities

Current
assets are assets held for trading purposes and assets expected to be converted to cash, sold or consumed within one year from the balance sheet date.    Current liabilities are obligations incurred for trading purposes and
obligations expected to be settled within one year from the balance sheet date.    Assets and liabilities that are not classified as current are noncurrent assets and liabilities, respectively.

Cash Equivalents

Repurchase agreements collateralized by government bonds, corporate bonds, and agency bonds acquired with maturities of less than three months from the date of purchase are classified as cash
equivalents.    The carrying amount approximates fair value due to their short term nature.

Financial
Assets/Liabilities at Fair Value Through Profit or Loss

Derivatives that do not meet the criteria for hedge accounting
are initially recognized at fair value, with transaction costs expensed as incurred.    The derivatives are remeasured at fair value subsequently with changes in fair value recognized in earnings.    A regular
way purchase or sale of financial assets is accounted for using settlement date accounting.

Fair value is estimated using
valuation techniques incorporating estimates and assumptions that are consistent with prevailing market conditions.    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.

Available-for-sale Financial Assets

Investments designated as available-for-sale financial assets include debt securities and equity
securities.    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 shareholders 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 settlement date accounting.

Fair value is determined as follows:    Money market funds - net asset values at the end of the year; publicly traded stocks - closing prices at the end of the year; and other debt
securities - average of bid and asked prices at the end of the year.

Cash dividends are recognized as investment income upon
resolution of shareholders of an investee but are accounted for as a reduction to the original cost of investment if such dividends are declared on the earnings of the investee attributable to the period prior to the purchase of the
investment.    Stock dividends are recorded as an increase in the number of shares held and do not affect investment income.    The cost per share is recalculated based on the new total number of shares.

Any difference between the initial carrying amount of a debt security and the amount due at maturity is amortized using the
effective interest method, with the amortization recognized in earnings.

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, for equity securities, the previously recognized impairment loss is reversed to the extent of the
decrease and recorded as an adjustment to shareholders 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.

##### Table of Contents

Held-to-maturity Financial Assets

Debt securities for which the Company has a positive intention and ability to hold to maturity are categorized as held-to-maturity
financial assets and are carried at amortized cost.    Those financial assets are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition.    Gains or losses
are recognized at the time of derecognition, impairment or amortization.    A regular way purchase or sale of financial assets is accounted for using settlement date accounting.

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.

Hedging Derivative Financial Instruments

Hedge derivatives are mainly derivatives instruments that are for cash flow hedge purposes and determined to be an effective hedge.    The portion of the gain or loss on the hedging
instrument that is determined to be an effective hedge is recognized in shareholders equity.    The amount recognized in shareholders equity is recognized in profit or loss in the same year or year during which the
hedged forecast transaction or an asset or liability arising from the hedged forecast transaction affects profit or loss.    However, if all or a portion of a loss recognized in shareholders equity is not expected to be
recovered in the future, the amount that is not expected to be recovered is reclassified into profit or loss.

Financial
Assets Carried at Cost

Investments for which the Company does not exercise significant influence and that do not have a
quoted market price in an active market and whose fair value cannot be reliably measured, such as non-publicly traded stocks and mutual funds, are carried at their original cost.    The costs of non-publicly traded stocks and
mutual funds are determined using the weighted-average method.    If there is objective evidence which indicates that a financial asset is impaired, a loss is recognized.    A subsequent reversal of such
impairment loss is not allowed.

The accounting treatment for cash dividends and stock dividends arising from financial assets
carried at cost is the same as that for cash and stock dividends arising from available-for-sale financial assets.

Allowance for Doubtful Receivables

An allowance for doubtful receivables is provided based on a review of the collectability of receivables.    The Company assesses the collectability of receivables by performing the
account aging analysis and examining current trends in the credit quality of its customers.

TSMCs provision was
originally set at 1% of the amount of outstanding receivables.    On January 1, 2011, the Company adopted the third revision of Statement of Financial Accounting Standards (SFAS) No. 34, Financial
Instruments:    Recognition and Measurement (SFAS No. 34).    One of the main revisions is that the impairment of receivables originated by the Company is subject to the provisions of SFAS
No. 34.    Accordingly, the Company evaluates for indication of impairment of accounts receivable based on an individual and collective basis at the end of each reporting period.    When objective
evidence indicates that the estimated future cash flow of accounts receivable decreases as a result of one or more events that occurred after the initial recognition of the accounts receivable, such accounts receivable are deemed to be impaired.

Because of the Companys short average collection period, the amount of the impairment loss recognized is the difference
between the carrying amount of accounts receivable and estimated future cash flows without considering the discounting effect.    Changes in the carrying amount of the allowance account are recognized as bad debt expense which is
recorded in the operating expenses - general and administrative.    When accounts receivable are considered uncollectable, the amount is written off against the allowance account.

Inventories

Inventories are recorded at standard cost and adjusted to approximate weighted-average cost on the balance sheet date.

Inventories are stated at the lower of cost or net realizable value.    Inventory write-downs are made on an item-by-item basis, except where it may be appropriate to group similar or
related items.    Net realizable value is the estimated selling price of inventories less all estimated costs of completion and necessary selling costs.

Investments Accounted for Using Equity Method

Investments in companies
wherein the Company exercises significant influence over the operating and financial policy decisions are accounted for using the equity method.    The Companys share of the net income or net loss of an investee is
recognized in the equity in earnings/losses of equity method investees, net account.    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
investees 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 capital surplus.    Cash dividends received from an investee
shall reduce the carrying amount of the investment. Stock dividends are recorded as an increase in the number of shares held and do not affect investment income.

Gains or losses on sales from the Company to equity method investees or from equity method investees to the Company are deferred in proportion to the Companys ownership percentages in the investees
until such gains or losses are realized through transactions with third parties.

If an investees functional currency is
a foreign currency, differences will result from the translation of the investees financial statements into the reporting currency of the Company.    Such differences are charged or credited to cumulative translation
adjustments, a separate component of shareholders equity.

Property, Plant and Equipment and Assets Leased to Others

Property, plant and equipment and assets leased to others are stated at cost less accumulated
depreciation.    Properties covered by agreements qualifying as capital leases are carried at the lower of the leased equipments market value or the present value of the minimum lease payments at the inception date of the
lease, with the corresponding amount recorded as obligations under capital leases.    Borrowing costs directly attributable to the acquisition or construction of property, plant and equipment are capitalized as part of the cost
of those assets.    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.    Significant additions, renewals and betterments incurred during the construction period are capitalized.    Maintenance and repairs are expensed
as incurred.

Depreciation is computed using the straight-line method over the following estimated service lives: land
improvements - 20 years; buildings - 10 to 20 years; machinery and equipment - 3 to 5 years; office equipment - 3 to 15 years; and leased assets - 20 years.

Upon sale or disposal of property, plant and equipment and assets leased to others, the related cost and accumulated depreciation are deducted from the corresponding accounts, with any gain or loss
recorded as non-operating gains or losses in the year of sale or disposal.

When property, plant and equipment are determined
to be idle or useless, they are transferred to idle assets at the lower of the net realizable value or carrying amount.    Depreciation on the idle assets is provided continuously, and the idle assets are tested for impairment on
a periodical basis.

Intangible Assets

Goodwill represents the excess of the consideration paid for acquisition over the fair value of identifiable net assets
acquired.    Goodwill is no longer amortized and instead is tested for impairment annually, or more frequently if events or changes in circumstances suggest that the carrying amount may not be
recoverable.    If an event occurs or circumstances change which indicate that the fair value of goodwill is more likely than not below its carrying amount, an impairment loss is recognized.    A subsequent
reversal of such impairment loss is not allowed.

Deferred charges consist of technology license fees, software and system
design costs and patent and others.    The amounts are amortized over the following periods:    Technology license fees - the estimated life of the technology or the term of the technology transfer contract;
software and system design costs - 2 to 5 years; patent and others - the economic life or contract period.    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 previously recognized impairment loss 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 amortization, as if no impairment loss had been recognized.

Expenditures related to research activities and those related to development activities that do not meet the criteria for capitalization are charged to expense when incurred.

Pension Costs

For employees who participate in defined contribution pension plans, pension costs are recorded based on the actual contributions made to employees individual pension accounts during their service
periods.    For employees who participate in defined benefit pension plans, pension costs are recorded based on actuarial calculations.

Income Tax

The Company applies an inter-period allocation for its income
tax whereby deferred income tax assets and liabilities are recognized for the tax effects of temporary differences, net operating loss carryforwards 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.

Any tax credits arising from purchases of machinery and equipment, research and development
expenditures and personnel training expenditures 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 tax on unappropriated
earnings (excluding earnings from foreign consolidated subsidiaries) at a rate of 10% is expensed in the year of shareholder approval which is the year subsequent to the year the earnings are generated.

Stock-based Compensation

Employee stock options that were granted or modified in the period from January 1, 2004 to December 31, 2007 are accounted for by the interpretations issued by the Accounting Research and
Development Foundation of the Republic of China.    The Company adopted the intrinsic value method and any compensation cost determined using this method is recognized in earnings over the employee vesting
period.    Employee stock option plans that were granted or modified after December 31, 2007 are accounted for using fair value method in accordance with SFAS No. 39, Accounting for Share-based
Payment.    The Company did not grant or modify any employee stock options since January 1, 2008.

Treasury Stock

Treasury stock represents the outstanding shares that the
Company buys back from market, which is stated at cost and shown as a deduction in shareholders equity.    When the Company retires treasury stock, the treasury stock account is reduced and the common stock as well as the
capital surplus - additional paid-in capital are reversed on a pro rata basis.    When the book value of the treasury stock exceeds the sum of the par value and additional paid-in capital, the difference is charged to capital
surplus - treasury stock transactions and to retained earnings for any remaining amount.    When the Company resells the treasury stock, the treasury stock shall be reversed, and if the selling price is greater than the book
value, the amount in excess of the book value shall be credited to additional paid-in capital - treasury stock.

Revenue Recognition and Allowance for Sales Returns and Others

The Company recognizes revenue when evidence of an arrangement exists, the rewards of ownership and significant risk of the goods has
been transferred to the buyer, price is fixed or determinable, and collectability is reasonably assured.    Provisions for estimated sales returns and other allowances are recorded in the year the related revenue is recognized,
based on historical experience, managements judgment, and any known factors that would significantly affect the allowance.

Sales prices are determined using fair value taking into account related sales discounts agreed to by the Company and its customers.    Sales agreements typically provide that payment
is due 30 days from invoice date for a majority of the customers and 30 to 45 days after the end of the month in which sales occur for some customers.    Since the receivables from sales are collectible within one year and such
transactions are frequent, fair value of the receivables is equivalent to the nominal amount of the cash to be received.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, receivables, investments and
deposits.    The Company limits its exposure to credit loss by depositing its cash and cash equivalents with high credit rating financial institutions.    The Companys sales are primarily denominated in
U.S. dollars.    Sales to top ten customers represented 53%, 54% and 56% of the consolidated sales for the years ended December 31, 2009, 2010 and 2011, respectively.    The Company routinely assesses the
financial strength of substantially all customers.    The financial condition of the counter-party to investments and deposits is assessed by management on a regular basis.

Fair Values of Financial Instruments

The carrying amount of cash equivalents approximates fair value due to the short period of time to maturity.    Fair values of investments in equity or debt securities and derivative
financial instruments are based on quoted market prices or pricing models using current market data. Receivables, other financial assets, payables and short-term loans are financial instruments with carrying amounts that approximate fair
values.    Fair value of long-term loans with floating interest rates is their carrying amount.    Fair value of long-term loans with fixed interest rates is the present value of expected cash flows discounted
using the interest rate the Company may obtain for similar long-term loans. For the Companys investment portfolio without immediately available market quotes, management believes that the carrying amount of the portfolio approximates the fair
value at December 31, 2010 and 2011.

Earnings Per Share

Earnings per share is computed by dividing income attributable to shareholders of the parent by the weighted-average number of shares
outstanding in each year, which is retroactively adjusted for stock dividends until 2008.    Earnings per equivalent ADS is calculated by multiplying earnings per share by five (one ADS represents five common shares).

The
Company maintains its accounts and expresses its consolidated financial statements in New Taiwan dollars.    For convenience only, U.S. dollar amounts presented in the accompanying consolidated financial statements have been
translated from New Taiwan dollars at the exchange rate as set forth in the statistical release of the Federal Reserve Board, which was NT$30.27 to US$1.00 as of December 30, 2011.    The convenience translations should not
be construed as representations that the New Taiwan dollar amounts have been, could have been, or could in the future be, converted into U.S. dollars at this or any other rate of exchange.

Effect of Adopting the Newly Released and Revised R.O.C. SFASs

On January 1, 2011, the Company prospectively adopted the newly revised SFAS No. 34, Financial Instruments: Recognition and Measurement.    The main revisions
include (1) finance lease receivables are now covered by SFAS No. 34; (2) the scope of the applicability of SFAS No. 34 to insurance contracts is amended; (3) loans and receivables originated by the Company are now covered
by SFAS No. 34; (4) additional guidelines on impairment testing of financial assets carried at amortized cost when the debtor has financial difficulties and the terms of obligations have been modified; and (5) accounting treatment by
a debtor for modifications in the terms of obligations.    This accounting change did not have a significant effect on the Companys consolidated financial statements as of and for the year ended December 31, 2011.

##### Table of Contents

On January 1, 2011, the Company adopted the newly issued SFAS No. 41,
Operating Segments.    The statement requires identification and disclosure of operating segments on the basis of how the Companys chief operating decision maker regularly reviews information in order to
allocate resources and assess performance.    This statement supersedes SFAS No. 20, Segment Reporting.    The Company conformed to the disclosure requirements as of and for the year ended
December 31, 2011.    The information for the years ended December 31, 2009 and 2010 has been recast to reflect the new segment reporting requirement.

Effective January 1, 2009, the Company adopted the newly revised SFAS No. 10, Accounting for
Inventories.    The main revisions are (1) inventories are stated at the lower of cost or net realizable value, and inventories are written down to net realizable value on an item-by-item basis except when the grouping
of similar or related items is appropriate; (2) unallocated overheads are recognized as expenses in the year in which they are incurred; and (3) abnormal cost, write-downs of inventories and any reversal of write-downs are recorded as cost
of sales for the year. Such a change in accounting principle did not have significant effect on the Companys consolidated financial statements as of and for the year ended December 31, 2009.

The Company entered into derivative contracts during the years ended December 31, 2009, 2010 and
2011 to manage exposures due to fluctuations of foreign exchange rates.    The derivative contracts entered into by the Company did not meet the criteria for hedge accounting.    Therefore, the Company did not
apply hedge accounting treatment for derivative contracts.

The Company has no controlling interest over GUC and its subsidiaries since July 2011, due to the
termination of a Shareholders Agreement.    However, the Company has significant influence over them and therefore, they are no longer consolidated and are accounted for using the equity method.

The Company originally owned 43% of Aiconn, which was merged with Accton Wireless Broadband Corp. (Accton) in March
2011.    As a result of the merger, the Companys equity investment in Aiconn was exchanged for equity of Accton and the Company did not exercise significant influence over Accton.    Therefore, the
aforementioned investment was reclassified to financial assets carried at cost.

In February 2010, the Company subscribed to
75,316 thousand shares of Motech through a private placement for NT$6,228.7 million; after the subscription, the Companys percentage of ownership in Motech was 20%.    Transfer of the aforementioned common shares
within three years is prohibited unless permitted by other related regulations.

For the years ended December 31, 2009,
2010 and 2011, equity in earnings/losses of equity method investees was a net gain of NT$46.0 million, NT$2,298.2 million and NT$897.6 million, respectively.    Related equity in earnings/losses of equity method investees were
determined based on the audited financial statements, except for Aiconn and Mcube. The Company believes that, had the aforementioned equity method investees financial statements been audited, any adjustments arising would have had no material
effect on the Companys consolidated financial statements.

The Companys long-term bank loans bear floating interest rates; therefore, changes in the market
interest rate may cause future cash flows to be volatile.    Accordingly, the Company entered into an interest rate swap contract in order to hedge cash flow risk caused by floating interest rates.    The
outstanding interest rate swap contract consisted of the following:

In June 2010, the Company invested in Stion Corporation (Stion, a United States corporation) for US$50.0
million and obtained Stions preferred stock of 7,347 thousand shares with 23.4% of ownership.    Stion is engaged in the manufacturing of high-efficiency thin-film solar photovoltaic modules.    Due
to certain restrictions contained in the investment agreements, the Company does not have the ability to exert significant influence over Stions operating and financial policies.    Therefore, the investment was classified
under financial assets carried at cost.

The common stock of InvenSense, Inc. was listed on the NYSE in November
2011.    Thus, the Company reclassified the aforementioned investments from financial assets carried at cost to available-for-sale financial assets.

The common stock of Capella Microsystems (Taiwan), Inc. and Integrated Memory Logic Limited was listed on the Taiwan GreTai Securities Market and Taiwan Stock Exchange in June 2010 and May 2010,
respectively.    Thus, the Company reclassified the aforementioned investments from financial assets carried at cost to available-for-sale financial assets.

For the years ended December 31, 2009, 2010 and 2011, the Company recognized impairment on financial assets carried at cost of
NT$711.9 million, NT$159.8 million and NT$265.5 million, respectively.

The payables for royalties were primarily attributable to several license arrangements that the Company
entered into for certain semiconductor-related patents.





|20. | PENSION PLANS
|--- | -------------

The
pension mechanism under the Labor Pension Act (the Act) is deemed a defined contribution plan.    Pursuant to the Act, TSMC, GUC, Xintec, Mutual-Pak, TSMC SSL and TSMC Solar have made monthly contributions equal to 6%
of each employees monthly salary to employees pension accounts.    Furthermore, TSMC North America, TSMC China, TSMC Europe, TSMC Canada, TSMC Solar NA and TSMC Solar Europe GmbH are required by local regulations to
make monthly contributions at certain percentages of the basic salary of their employees.    Pursuant to the aforementioned Act and local regulations, the Company recognized pension costs of NT$748.1 million, NT$1,121.7 million
and NT$1,297.6 million for the years ended December 31, 2009, 2010 and 2011, respectively.

TSMC, GUC, Xintec, TSMC SSL
and TSMC Solar have defined benefit plans under the Labor Standards Law that provide benefits based on an employees length of service and average monthly salary for the six-month period prior to retirement.    The
aforementioned companies contribute an amount equal to 2% 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
Committees name in the Bank of Taiwan.

| | h. | Plan assets allocation
| | -- | ----------------------

The
government is responsible for the administration of all the defined benefit plans for the companies in Taiwan under the Labor Standards Law. The government also sets investment policies and strategies, determines investment allocation and selects
investment managers. As of December 31, 2010 and 2011, the asset allocation was primarily in cash, equity securities and debt securities. Furthermore, under the Labor Standards Law, the rate of return on assets shall not be less than the
average interest rate on a two-year time deposit published by the local banks and the government is responsible for any shortfall in the event that the rate of return is less than the required rate of return. However, information on how investment
allocation decisions are made, inputs and valuation techniques used to measure the fair value of plan assets, the effect of fair value measurements using significant unobservable inputs on changes in plan assets for the period and significant
concentrations of risk within plan assets is not fully made available to the companies by the government. Therefore, the Company is unable to provide the required fair value disclosures related to pension plan assets.

Effective in May 2009 and May 2010, the Article 5 of the Income Tax Law of the Republic of China was
amended, in which the income tax rate of profit-seeking enterprises would be reduced from 25% to 20% and from 20% to 17%, respectively.    The last amended income tax rate of 17% is retroactively applied on January 1,
2010.    TSMC and its domestic subsidiaries which are subject to the Income Tax Law of the Republic of China recalculated their deferred tax assets in accordance with the new amended Article and adjusted the resulting difference
as an income tax expense in 2009 and 2010, respectively.    The Company evaluated the effect of Alternative Minimum Tax and applicable year of the profits generated from projects exempt from income tax for a five-year
period.    As the Company plans to apply the tax-exempt income in later years, income tax payable is anticipated to increase and the Company will utilize available investment tax credits as an offset against income
taxes.    Since more investment tax credits can be utilized, valuation allowance has been adjusted down accordingly.

Under the Article 10 of the Statute for Industrial Innovation (SII) legislated, effective in May 2010, a profit-seeking enterprise may deduct up to 15% of its research and development expenditures from
its income tax payable for the year in which these expenditures are incurred, but this deduction should not exceed 30% of the income tax payable for that year.    This incentive is retroactive to January 1, 2010 and
effective until December 31, 2019.

As of December 31, 2011, the net operating loss carryforwards generated by
WaferTech, TSMC Development, Mutual-Pak, TSMC SSL and TSMC Solar would expire on various dates through 2023.

Capital surplus can be used to offset a deficit under the Company
Law.    However, the capital surplus generated from donations and the excess of the issuance price over the par value of capital stock (including the stock issued for new capital, mergers, convertible bonds and the surplus from
treasury stock transactions) may be appropriated as stock dividends, which are limited to a certain percentage of TSMCs paid-in capital.    In addition, the capital surplus from long-term investments may not be used for any
purpose.    However, according to the revised Company Law, effective January 2012, the aforementioned capital surplus generated from donations and the excess of the issuance price over the par value of capital stock can also be
used to distribute cash in proportion to original shareholders holding.

Capital surplus consisted of the following:

TSMCs Articles of Incorporation provide that, when allocating the net profits for each fiscal year,
TSMC shall first offset its losses in previous years and then set aside the following items accordingly:



| | a. | Legal capital reserve at 10% of the profits left over, until the accumulated legal capital reserve equals TSMCs paid-in capital;
| | -- | ---------------------------------------------------------------------------------------------------------------------------------



| | b. | Special capital reserve in accordance with relevant laws or regulations or as requested by the authorities in charge;
| | -- | ---------------------------------------------------------------------------------------------------------------------



| | c. | Bonus to directors and profit sharing to employees of TSMC of not more than 0.3% and not less than 1% of the remainder, respectively.    Directors
who also serve as executive officers of TSMC are not entitled to receive the bonus to directors.    TSMC may issue profit sharing to employees in stock of an affiliated company meeting the conditions set by the Board of Directors
or, by the person duly authorized by the Board of Directors;
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | d. | Any balance left over shall be allocated according to the resolution of the shareholders meeting.
| | -- | --------------------------------------------------------------------------------------------------

TSMCs Articles of Incorporation also provide that profits of TSMC may be distributed by way of cash dividend and/or stock
dividend.    However, distribution of profits shall be made preferably by way of cash dividend.    Distribution of profits may also be made by way of stock dividend; provided that the ratio for stock dividend
shall not exceed 50% of the total distribution.

##### Table of Contents

Any appropriations of the profits are subject to shareholders approval in the
following year.

TSMC accrued profit sharing to employees based on certain percentage of net income during the year, which
amounted to NT$10,908.3 million and NT$8,990.0 million for the years ended December 2010 and 2011, respectively. Bonuses to directors were expensed based on estimated amount of payment.    If the actual amounts subsequently
resolved by the shareholders differ from the estimated amounts, the differences are recorded in the year of shareholders resolution as a change in accounting estimate.    If profit sharing is resolved to be distributed to
employees in stock, the number of shares is determined by dividing the amount of profit sharing by the closing price (after considering the effect of dividends) of the shares on the day preceding the shareholders meeting.

TSMC no longer has supervisors since January 1, 2007. The required duties of supervisors are being fulfilled by the Audit Committee.

##### Table of Contents

According to the revised Company Law, effective January 2012, the appropriation for legal
capital reserve shall be made until the reserve equals the Companys paid-in capital.    The reserve may be used to offset a deficit, or be distributed as dividends in cash or stocks for the portion in excess of 25% of the
paid-in capital if the Company incurs no loss.

A special capital reserve equivalent to the net debit balance of the other
components of shareholders equity (for example, cumulative translation adjustments and unrealized loss on financial instruments, but excluding treasury stock) shall be made from unappropriated earnings pursuant to existing regulations
promulgated by the Securities and Futures Bureau (SFB).    Any special reserve appropriated may be reversed to the extent that the net debit balance reverses.

The appropriations of earnings for 2009 and 2010 had been approved in TSMCs shareholders meetings held on June 15, 2010
and June 9, 2011, respectively.    The appropriations and dividends per share were as follows:

The requisite service period under the TSMC 2002 Plan, 2003 Plan, and 2004 Plan is 4 years, which is the
same as the vesting period. Based on the vesting schedule, 50% of the options vest two years after the date of grant, 25% of the options vest three years after the date of grant, and the remaining 25% of the options vest four years after the date of
grant. If employment is terminated voluntarily by an employee or by the Company, any vested options must be exercised within three months of the employment termination date.    For the Xintec 2006 Plan and 2007 Plan, the
requisite service period is also 4 years, with 50% of the options vested two years after the date of grant, 25% of the options vested three years after the date of grant, and the remaining 25% of the options vested four years after the date of
grant. If employment is terminated voluntarily by an employee or by the Company, any vested options must be exercised within three months of the employment termination date.

No compensation cost was recognized under the intrinsic value method for the years ended December 31, 2009, 2010 and 2011.    Had the Company used the fair value based method to
evaluate the options using the Black-Scholes model, the assumptions at the various grant dates and pro forma results of the Company for the years ended December 31, 2009, 2010 and 2011 would have been as follows:

The expected volatility is determined based on the historical stock price trends. The expected life
computation is based on business environment and the option plan itself. The risk-free interest rate for periods within the contractual life of the option is based on the treasury yield curve in effect at the time of grant. The dividend yield is
based on the anticipated future cash dividends yield at the time of grant.

##### Table of Contents

If the Company may settle the obligation by cash, by issuing shares, or in combination of
both cash and shares, profit sharing to employees which will be settled in shares should be included in the weighted average number of shares outstanding in calculation of diluted EPS, if the shares have a dilutive effect.    The
number of shares is estimated by dividing the amount of profit sharing to employees in stock by the closing price (after considering the dilutive effect of dividends) of the common shares on the balance sheet date.    Such
dilutive effect of the potential shares needs to be included in the calculation of diluted EPS until the shares of profit sharing to employees are resolved in the shareholders meeting in the following year.

The average number of shares outstanding for EPS calculation has been considered for the effect of retroactive
adjustment.    This adjustment caused each of the basic and diluted after income tax EPS for the year ended December 31, 2009 to remain at NT$3.45 and NT$3.44, respectively.    This adjustment caused each
of the basic and diluted after income tax EPS for the year ended December 31, 2010 to remain at NT$6.24 and NT$6.23, respectively.

| | 1) | The aforementioned financial instruments do not include cash and cash equivalents, receivables, other financial assets, refundable deposits, short-term loans, payables
and guarantee deposits.    The carrying amounts of these financial instruments approximate their fair values due to their short maturities.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2) | Except for derivatives, available-for-sale and held-to-maturity financial assets were based on their quoted market prices.
| | -- | --------------------------------------------------------------------------------------------------------------------------



| | 3) | The fair values of those derivatives are determined using valuation techniques incorporating estimates and assumptions that were consistent with prevailing market
conditions.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4) | Financial assets carried at cost 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.

| | f. | Information about financial risks
| | -- | ---------------------------------



| | 1) | Market risk.    The derivative financial instruments categorized as financial assets/liabilities at fair value through profit or loss are mainly
used to hedge the market exchange rate fluctuations of foreign-currency assets and liabilities; therefore, the market exchange rate risk of derivatives will be offset by the foreign exchange risk of these hedged
items.    Available-for-sale financial assets and held-to-maturity financial assets held by the Company are mainly fixed-interest-rate debt securities and publicly traded stocks; therefore, the fluctuations in market interest
rates and market prices will result in changes in fair values of these debt securities.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 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 Company evaluated whether the financial instruments for any possible
counter-parties or third-parties are reputable financial institutions, business enterprises, and government agencies and accordingly, the Company believed that the Companys exposure to credit risk was not significant.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3) | Liquidity risk.    The Company has sufficient operating capital and bank facilities to meet cash needs upon settlement of derivative financial
instruments, bonds payable and bank loans.    Therefore, the liquidity risk is low.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4) | Cash flow interest rate risk.    The Company mainly invests in fixed-interest-rate debt securities.    Therefore, cash flows are
not expected to fluctuate significantly due to changes in market interest rates.    The long-term bank loans were floating-rate loans; therefore, changes in the market interest rates will result in changes in the interest rate of
the long-term bank loans, which will affect future cash flows.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | g. | The Company seeks to reduce the effects of future cash flow related interest rate changes by primarily using derivative financial instruments.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------

The Companys long-term bank loans bear floating interest rates; therefore, changes in the market interest rate may cause future
cash flows to be volatile.    Accordingly, the Company entered into an interest rate swap contract in order to hedge cash flow risk caused by floating interest rates.    Information about outstanding interest
rate swap contract consisted of the following:

|30. | SIGNIFICANT COMMITMENTS AND CONTINGENCIES
|--- | -----------------------------------------

Significant commitments and contingencies of the Company as of December 31, 2011, excluding those disclosed in other notes, were as follows:



| | a. | Under a technical cooperation agreement with Industrial Technology Research Institute, the R.O.C. Government or its designee approved by TSMC can use up to 35% of
TSMCs capacity if TSMCs outstanding commitments to its customers are not prejudiced.    The term of this agreement is for five years beginning from January 1, 1987 and is automatically renewed for successive
periods of five years unless otherwise terminated by either party with one year prior notice.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b. | Under several foundry agreements, TSMC shall reserve a portion of its production capacity for certain major customers that have guarantee deposits with
TSMC.    As of December 31, 2011, TSMC had a total of US$13.0 million of guarantee deposits.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c. | Under a Shareholders Agreement entered into with Philips and EDB Investments Pte Ltd. on March 30, 1999, the parties formed a joint venture company, SSMC, which is
an integrated circuit foundry in Singapore.    TSMCs equity interest in SSMC was 32%.    Nevertheless, Philips parted with its semiconductor company which was renamed as NXP B.V. in September
2006.    TSMC and NXP B.V. purchased all the SSMC shares owned by EDB Investments Pte Ltd. pro rata according to the Shareholders Agreement on November 15, 2006.    After the purchase, TSMC and NXP B.V.
currently own approximately 39% and 61% of the SSMC shares respectively.    TSMC and Philips (now NXP B.V.) are required, in the aggregate, to purchase at least 70% of SSMCs capacity, but TSMC alone is not required to
purchase more than 28% of the capacity.    If any party defaults on the commitment and the capacity utilization of SSMC fall below a specific percentage of its capacity, the defaulting party is required to compensate SSMC for all
related unavoidable costs.

| | d. | In August 2006, TSMC filed a lawsuit against Semiconductor Manufacturing International Corporation, SMIC (Shanghai) and SMIC Americas (aggregately referred to as
SMIC) in the Superior Court of California for Alameda County for breach of a 2005 agreement that settled an earlier trade secret misappropriation and patent infringement litigation between the parties, as well as for trade secret
misappropriation, seeking injunctive relief and monetary damages.    In September 2006, SMIC filed a cross-complaint against TSMC in the same court alleging breach of settlement agreement, implied covenant of good faith and fair
dealing.    SMIC also filed a civil action against TSMC in November 2006 with the Beijing Peoples High Court alleging defamation and breach of good faith.    On June 10, 2009, the Beijing
Peoples High Court ruled in favor of TSMC and dismissed SMICs lawsuit.    On November 4, 2009, after a two-month trial, a jury in the California action found SMIC to have both breached the 2005 settlement
agreement and misappropriated TSMCs trade secrets.    TSMC has subsequently settled both lawsuits with SMIC.    Pursuant to the new settlement agreement, the parties have agreed to the entry of a
stipulated judgment in favor of TSMC in the California action, and to the dismissal of SMICs appeal against the Beijing High Courts finding in favor of TSMC.    Under the new settlement agreement and the related
stipulated judgment, SMIC has agreed to make cash payments by installments to TSMC totaling US$200 million, which are in addition to the US$135 million previously paid to TSMC under the 2005 settlement agreement, and, conditional upon relevant
government regulatory approvals, to issue to TSMC a total of 1,789,493,218 common shares of Semiconductor Manufacturing International Corporation and a three-year warrant to purchase 695,914,030 common shares (subject to adjustment) of Semiconductor
Manufacturing International Corporation at HK$1.30 per share (subject to adjustment).    TSMC has received the approval from the Investment Commission of Ministry of Economic Affairs and acquired the above mentioned common shares
in July 2010, which are recorded within available for sale financial assets, and obtained the subsequent cash settlement income in accordance with the agreement.

| | e. | In June 2010, Keranos, LLC. filed a lawsuit in the U.S. District Court for the Eastern District of Texas alleging that TSMC, TSMC North America, and several other
leading technology companies infringe three expired U.S. patents.    In response, TSMC, TSMC North America, and several co-defendants in the Texas case filed a lawsuit against Keranos in the U.S. District Court for the Northern
District of California in November 2010, seeking a judgment declaring that they did not infringe the asserted patents, and that those patents are invalid.    These two litigations have been consolidated into a single case in the
U.S. District Court for the Eastern District of Texas. The outcome cannot be determined at this time.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | f. | In December 2010, Ziptronix, Inc. filed a complaint in the U.S. District Court for the Northern District of California accusing TSMC, TSMC North America and one other
company of allegedly infringing six U.S. patents. This litigation is in its very early stages and therefore the outcome of the case cannot be determined at this time.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | g. | TSMC entered into an agreement with a counterparty in 2003 whereby TSMC China is obligated to purchase certain property, plant and equipment at the agreed-upon price
within the contract period.    If the purchase is not completed, TSMC China is obligated to compensate the counterparty for the loss incurred.    The property, plant and equipment have been in use by TSMC
China since 2004 and are being depreciated over their estimated service lives.    The related obligation totaled NT$7,112.2 million and NT$3,399.9 million as of December 31, 2010 and 2011, respectively, which is included in
other long-term payables.

##### Table of Contents

| | b. | As of December 31, 2011, from the Companys assessment, the significant differences between the Companys current accounting policies under R.O.C. GAAP
and the ones under IFRSs are stated as follows:
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Allowance for sales returns and others

Under R.O.C. GAAP, provisions for estimated sales returns and others are recognized as a reduction in revenue in the period the related
revenue is recognized based on historical experience.    Allowance for sales returns and others is recorded as a deduction in accounts receivable.    Under IFRSs, the allowance for sales returns and others is
a present obligation with uncertain timing and an amount that arises from past events and is therefore reclassified as provisions (classified under current liabilities) accordingly.

Classifications of deferred income tax asset/liability and valuation allowance

Under R.O.C. GAAP, a deferred tax asset or liability is classified as current or non-current in accordance with the classification of its
related asset or liability.    However, if a deferred income tax asset or liability does not relate to an asset or liability in the financial statements, it is classified as either current or non-current based on the expected
length of time before it is realized or settled.    Under IFRSs, a deferred tax asset or liability is classified as non-current asset or liability.

In addition, under R.O.C. GAAP, 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.    Under
IFRSs, deferred tax assets are only recognized to the extent that it is probable that there will be sufficient taxable profits and the valuation allowance account is no longer used.

The classification of leased assets and idle assets

Under R.O.C. GAAP, leased assets and idle assets are classified under other assets.    Under IFRSs, the aforementioned items are classified as property, plant and equipment according
to their nature.    Leased assets are mainly dormitories leased to employees and factories leased to suppliers.    In accordance with the relevant IFRSs guidance, the dormitories leased to employees are not
classified as investment properties; factories leased to suppliers are not considered as investment properties since they cannot be sold separately and comprise only an insignificant portion of the plant.

Employee benefits

The Company had previously applied an actuarial valuation on its defined benefit obligation and recognized the related pension cost and retirement benefit obligation in conformity with R.O.C.
GAAP.    Under IFRSs, the Company should carry out actuarial valuation on defined benefit obligation in accordance with IAS No. 19, Employee Benefits.

Under R.O.C. GAAP, it is not allowed to recognize actuarial gains and losses from defined benefit plans directly to equity; instead,
actuarial gains and losses should be accounted for under the corridor approach which resulted in the deferral of gains and losses.    When using the corridor approach, actuarial gains and losses should be amortized over the
expected average remaining working lives of the participating employees.

Under IAS No. 19, Employee
Benefits, the Company will recognize actuarial gains and losses immediately in full in the period in which they occur, as other comprehensive income.    The subsequent reclassification to earnings is not permitted.

Investments accounted for using the equity method

The Companys associates and joint ventures accounted for using the equity method have also assessed the significant differences
between their respective present accounting policies and IFRSs.    The significant difference is mainly the adjustment to employee benefits.

The reclassification of line items in the statement of comprehensive income

In accordance with the Guidelines Governing the Preparation of Financial Reports by Securities Issuers before its amendment due to the
adoption of IFRSs, income from operations in the consolidated income statement only includes revenue, cost of sales and operating expenses.    Under IFRSs, based on the nature of operating transactions, technical service income
is reclassified under revenue; rental revenue, depreciation of rental assets, net loss on disposal of property, plant and equipment and intangible assets, and impairment loss of property, plant and equipment, are reclassified under other operating
gains and losses, which are reflected in income from operations.

|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 (R.O.C. GAAP), which differ in the following respects from accounting principles generally accepted in the United States of America (U.S. GAAP):



| | a. | Equity-method investees
| | -- | -----------------------

The
Companys proportionate share of the net income (loss) from an equity-method investee may differ if the equity-method investees net income (loss) under R.O.C. GAAP differs from that under U.S. GAAP. Such differences between R.O.C. GAAP
and U.S. GAAP would result in adjustments to investments accounted for using the equity method and the equity in earnings (losses) of equity-method investees recorded in net income.



| | b. | 10% tax on unappropriated earnings
| | -- | ----------------------------------

In the R.O.C., a 10% tax is imposed on unappropriated earnings (excluding earnings from foreign consolidated subsidiaries). For R.O.C. GAAP purposes, the Company records the 10% tax on unappropriated
earnings in the year of shareholders approval. In the U.S., the 10% tax on unappropriated earnings should be accrued during the period the earnings arise and adjusted to the extent that distributions are approved by the shareholders in the
following year. To the extent the Company does not have sufficient tax credits to offset the 10% tax, additional tax expense would be recognized under U.S. GAAP.



| | c. | Goodwill and intangible assets
| | -- | ------------------------------

Under R.O.C. GAAP, goodwill was recorded for the excess of the purchase price over the net tangible assets for the purchase of a 32%
equity interest in TSMC-Acer Semiconductor Manufacturing Corporation (TASMC) in 1999 and was amortized over ten years.    Under U.S. GAAP, the goodwill was originally amortized over five years.

Goodwill was not recorded under R.O.C. GAAP for the acquisition of the remaining 68% equity interest in TASMC in June 2000, because under
R.O.C. GAAP, goodwill from a business combination in the form of a share exchange was charged to capital surplus.    Under U.S. GAAP, the acquisition cost is the fair value of the shares issued in exchange and the difference
between the acquisition cost and the sum of the fair values of the net tangible and identifiable intangible assets acquired is recorded as goodwill.    Accordingly, the goodwill from the acquisition of the remaining 68% equity
interest in TASMC was recorded for U.S. GAAP purposes and was originally amortized over the estimated life of five years.

Effective January 1, 2002, the Company adopted the U.S. GAAP guidance relating to goodwill and other intangible assets and ceased
amortization of goodwill which is now assessed for impairment annually or more frequently if impairment indicators arise. In accordance with the U.S. GAAP guidance relating to goodwill and other intangible assets, the Company had completed its
goodwill impairment test at the reporting unit level and found no impairment as of December 31, 2009, 2010 and 2011.

##### Table of Contents

Effective January 1, 2005, the Company adopted R.O.C. SFAS No. 35,
Accounting for Impairment of Assets which required the Company to evaluate impairment of an asset group, including goodwill allocated to such group. The Company found no impairment as of December 31, 2009, 2010 and 2011. Effective
January 1, 2006, the Company adopted R.O.C. SFAS No. 25 (revised 2005), Business Combinations which is similar to U.S. GAAP guidance relating to goodwill and other intangible assets.    Upon adoption of
R.O.C. SFAS No. 25, the Company ceased amortization of goodwill which is now assessed for impairment in accordance with the provisions of the standard and R.O.C. SFAS No. 35.



| | d. | Profit sharing to employees in stocks
| | -- | -------------------------------------

The Company accrues compensation expense related to profit sharing to employees during the period the earnings arise.    The number of shares is determined based on the compensation
expense recorded during the period the earnings arise divided by the market value of the Companys common stock at the date before the shareholders meeting in the following year.    However, under U.S. GAAP, the amount
of compensation expense is the product of the number of shares and the market value at the date of stock distribution.    Therefore, any difference of the market value of the Companys common stock between the date of stock
distribution and the date before the shareholders meeting gives rise to adjustments to U.S. GAAP.



| | e. | Pension benefits
| | -- | ----------------

The U.S. GAAP
guidance relating to employers accounting for pensions was amended on September 29, 2006 to require employers to recognize the overfunded or underfunded status of a defined benefit pension plan as an asset or liability in its statement of
financial position and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. The funded status of a benefit plan is defined as the difference between the fair value of the plan assets and the
projected benefit obligation. Previously unrecognized items such as gains or losses, prior service credits and the transition asset or obligation are required to be recognized in other comprehensive income and subsequently recognized through net
periodic benefit cost.

R.O.C. SFAS No. 18 does not require a company to recognize the overfunded or underfunded status
of a defined benefit pension plan as an asset or liability in the statement of financial position. Due to the GAAP difference in pension accounting, there were adjustments to U.S. GAAP for the current year pension expense and other comprehensive
income.

The difference of the overfunded or underfunded status at the date of adoption and hereafter give rise to a U.S. GAAP
difference in the actuarial computation and the related amortization.



| | f. | Stock-based compensation
| | -- | ------------------------

Under
U.S. GAAP, effective January 1, 2006, the Company adopted the fair value recognition provisions to account for share-based payments, and applied the modified prospective transition method and therefore has not restated the results for prior
periods. Under this transition method, stock-based compensation expense for the year ended December 31, 2006 included compensation expense for all unvested stock-based compensation awards granted prior to January 1, 2006 that were expected
to vest, based on the grant-date fair value or the intrinsic value described in the next paragraph. Upon an employees termination, unvested awards are forfeited, which affects the quantity of options to be included in the calculation of
stock-based compensation expense. Forfeitures do not include vested options that expire unexercised. Stock-based compensation expense for all stock-based compensation awards granted after January 1, 2006 was based on the grant-date fair value.
The Company recognizes these compensation costs using the graded vesting method over the requisite service period of the award, which is generally the option vesting term of four years. See Note 35d for additional stock-based compensation
disclosures.

Under R.O.C. GAAP, employee stock option plans that were granted or modified in the period from January 1,
2004 to December 31, 2007 are accounted for by the interpretations issued by the ARDF. The Company adopted the intrinsic value method and any compensation expense determined using this method is recognized over the vesting period. No
stock-based compensation expense was recognized under R.O.C. GAAP for the years ended December 31, 2009, 2010 and 2011.

Effective January 1, 2008, the Company adopted R.O.C. SFAS No. 39, Accounting for Share-based Payment, which is
similar in many respects to U.S. GAAP and requires companies to record share-based payment transactions in the financial statements at fair value for the employee stock option plans that were granted or modified after December 31, 2007. The
Company did not grant or modify employee stock options since January 1, 2008.

Certain characteristics of the stock
options granted under the TSMC 2002 Plan is not reasonably estimable using appropriate valuation methodologies and have been accounted for using the variable accounting method under U.S. GAAP. Such method requires the Company to account for these
stock options based on their intrinsic value, remeasured at each reporting date through the date of exercise or settlement, which gives rise to a R.O.C. GAAP difference in the recognition of stock-based compensation expense.

| | g. | Consolidated entities
| | -- | ---------------------

Under
R.O.C. GAAP, the Company adopted R.O.C. SFAS No. 7, Consolidated Financial Statements, which requires that the accompanying consolidated financial statements include the accounts of all directly and indirectly majority owned
subsidiaries of TSMC, and the accounts of investees in which TSMCs ownership percentage is less than 50% but over which TSMC has a controlling interest. All significant intercompany balances and transactions are eliminated upon consolidation.
Partially owned, non-controlled equity investees are accounted for under the equity method.

U.S. GAAP has two different
models for determining whether consolidation is appropriate. If a reporting entity has a variable interest in another entity that meets the definition of a variable interest entity (VIE), the VIE model should be applied. Under this model,
consolidation is based on which interest holder has the power to direct the activities that most significantly impact the VIEs economics and has the right to receive benefits or the obligation to absorb the losses that could potentially be
significant to the VIE. However, if a reporting entity has an interest in an entity that is not considered a VIE, consolidation is based on whether the reporting enterprise has a controlling financial interest in the entity (i.e. the majority voting
interest requirement) which is similar to R.O.C. GAAP.



| | h. | Deconsolidation
| | -- | ---------------

Under R.O.C.
GAAP and U.S. GAAP, a parent must deconsolidate a subsidiary as of the date the parent ceases to have a controlling interest in that subsidiary. Under R.O.C. GAAP, the carrying amount of the investment on the date when control is lost should be
reflected as the cost on the initial measurement of such financial asset. However, under U.S. GAAP, the parents retained noncontrolling interest in the former subsidiary is remeasured to fair value with any resulting adjustments being included
as part of the gain or loss recognized on deconsolidation. The difference between the carrying amount and the fair value of the identifiable assets from the purchase price allocation process is amortized. Please refer to Note 35.g Deconsolidation of
GUC for details.

The Company reports comprehensive income (loss) in accordance with the guidance related to
reporting comprehensive income for U.S. GAAP purposes. The guidance related to reporting comprehensive income requires that in addition to net income (loss), a company should report other comprehensive income (loss) consisting of the changes in
equity of the company during the year from transactions and other events and circumstance from nonowner sources. It includes all changes in equity during the year except those resulting from investments by shareholders and distribution to
shareholders. The components of other comprehensive income for the Company consist of unrealized gains and losses relating to the translation of financial statements maintained in foreign currencies, unrealized gains and losses relating to the
Companys investments in available-for-sale securities and hedging derivative financial instruments and changes in actuarial gain or loss and transition obligation of the defined benefit pension plan.

Statements of comprehensive income for the years ended December 31, 2009, 2010 and 2011 are as follows:

The Company applies R.O.C. SFAS No. 17, Statement of Cash Flows. Its objectives and
principles are similar to those set out under U.S. GAAP. The principal differences between the two standards relate to classification. Changes in deferred charges, refundable deposits and other assets-miscellaneous under cash flows from investing
activities under R.O.C. GAAP are reclassified to operating activities under U.S. GAAP. Changes in guarantee deposits under cash flows from financing activities under R.O.C. GAAP are reclassified to operating activities under U.S. GAAP. Effect of
change in consolidated entities, which represents the cash decrease as a result of deconsolidation of GUC, is also reclassified to investing activities under U.S. GAAP guidance related to statement of cash flows.    Summarized
cash flow data by operating, investing and financing activities in accordance with U.S. GAAP guidance related to statement of cash flows are as follows:

35.   ADDITIONAL DISCLOSURES REQUIRED BY U.S. GAAP



| | a. | Recent accounting pronouncements
| | -- | --------------------------------

In September 2009, the FASB issued an accounting standard update which provides guidance on how to separate consideration in
multiple-deliverable arrangements and significantly expands disclosure requirements. The standard establishes a hierarchy for determining the selling price of a deliverable, eliminates the residual method of allocation and requires that arrangement
consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The update is effective for annual reporting periods beginning on or after June 15, 2010. This guidance is effective for
the Company for the year ended December 31, 2011. Based on the Companys analysis, the adoption of new guidance did not have a material effect on the Companys results of operations and financial position or cash flows as of and for
the year ended December 31,2011.

In January 2010, the FASB issued an accounting update that amended guidance and
clarified the disclosure requirements about fair market value measurement.    These amended standards require new disclosures for significant transfers of assets or liabilities between Level 1 and Level 2 in the fair value
hierarchy; separate disclosures for purchases, sales, issuance and settlements of Level 3 fair value items on a gross, rather than net basis; and more robust disclosure of the valuation techniques and inputs used to measure Level 2 and Level 3
assets and liabilities.    Except for the detailed disclosures of changes in Level 3 items, which will be effective for the Company as of January 1, 2011, the remaining new disclosure requirements are effective for the
Company as of January 1, 2010. The Company has included these new disclosures, as applicable, in Note 35b below.

In
December 2010, the FASB issued an accounting update requiring that supplemental pro forma information disclosures pertaining to acquisitions be presented as if the business combination(s) occurred as of the beginning of the prior annual accounting
period when comparative financial statements are presented.    This guidance also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments
directly attributable to the business combination included in the reported pro forma revenue and earnings.    This guidance is effective for business combinations consummated in periods beginning after December 15,
2010.    The Company will make the required disclosures prospectively from the date of the adoption for any material business combinations or series of immaterial business combinations that are material in the aggregate.

In May 2011, the 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 update is effective for annual reporting periods
beginning on or after December 15, 2011.    Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Companys results of operations and
financial position or cash flows.

In June and December 2011, the FASB issued an accounting update 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.    This guidance must be applied retroactively and is effective for fiscal years beginning after December 15, 2011. Earlier application is permitted. The Company has determined to present items
of net income and other comprehensive income in one continuous statement starting 2012.

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 annual and interim goodwill
impairment tests performed for fiscal years beginning after December 15, 2011. Based on the Companys analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Companys results of
operations and financial position or cash flows.

##### Table of Contents

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 this standard impacts disclosure requirements only, its adoption is not expected to have a material impact on the Companys
results of operations, financial condition or cash flows.



| | b. | Fair Value
| | -- | ----------

On January 1,
2008, the Company adopted the guidance related to fair value measurements, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements.

The guidance related to fair value measurements defines fair value as the price that would be received upon sale of an asset or paid upon
transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability.    The fair value should be calculated based on
assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the Company.

In addition to defining fair value, the guidance related to fair value measurements expands the disclosure requirements around fair value
and establishes a fair value hierarchy for valuation inputs.    The hierarchy prioritizes the inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the
market.    Each fair value measurement is reported in one of the three levels which is determined by the lowest level input that is significant to the fair value measurement in its entirety.    These levels
are:

Level 1 - Use unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 - Use observable inputs other than Level 1 prices such as quoted prices for identical or similar instruments in markets that are
not active, quoted prices for similar instruments in active markets, and model-based valuation in which all significant inputs are observable or can be corroborated by observable market data for substantially the full term of the assets or
liabilities.

Level 3 - Use inputs that are generally unobservable and reflect the use of significant management judgments and
estimates.

The following section describes the valuation methodologies the Company uses to measure financial assets and
liabilities at fair value.

The Company uses quoted prices in active markets for identical assets to determine fair value for
our Level 1 investments such as corporate bonds, agency bonds, publicly traded stocks, government bonds and money market funds.

For forward exchange and cross 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. The forward exchange and cross currency swap
contracts financial assets and liabilities are included in Level 2.

Financial assets carried at cost consist primarily of non-publicly traded stocks. The Company
reviews the carrying values of financial assets carried at cost when impairment indicators are present. Due to the absence of quoted market prices, the fair values are determined significantly based on management judgment with the best information
available. The Company calculates these fair values using the market approach which includes recent financing activities, valuation of comparable companies, technology development stage, market condition and other economic factors as their inputs.

The gross unrealized losses
related to bonds and publicly traded stock were due to fair value fluctuations. The Company presently does not intend to sell the above securities and believes that it is not more likely than not that the Company will be required to sell these
securities that are in an unrealized loss position before recovery of the Companys cost.

As of December 31, 2011,
the amortized cost and fair value of the Companys held-to-maturity investments in debt securities by contractual maturity were as follows:

| | d. | Stock-based compensation plans
| | -- | ------------------------------

Effective January 1, 2006, TSMC adopted the fair value recognition provisions to account for share-based payments, using the
modified prospective transition method and therefore has not restated the results for prior periods. Under the transition method, stock-based compensation expense in the year ended December 31, 2006 includes stock-based compensation expense for
all share-based payment awards granted prior to, but not yet vested as of January 1, 2006, based on the grant-date fair value. In addition, the stock-based compensation expense also includes intrinsic value of certain outstanding share-based
awards for which it was not possible to reasonably estimate their grant-date fair value.

##### Table of Contents

Stock-based compensation expense for all share-based payment awards granted after
January 1, 2006 is based on the grant-date fair value. The Company recognizes these compensation costs using the graded vesting method over the requisite service period of the award, which is generally a four-year vesting period. The adoption
of the guidance relating to share-based payment resulted in a cumulative gain from accounting change of NT$37.9 million, which reflects the net cumulative impact of estimating future forfeitures in the determination of period expense, rather than
recording forfeitures when they occur as previously permitted. In March 2005, the SEC issued an interpretation relating to share-based payment and the value of share-based payments for public companies. TSMC has applied the interpretation in its
adoption of the guidance relating to share-based payment. In December 2007, the SEC issued an amendment for prior interpretation regarding the use of the simplified method in developing estimates of the expected life of stock options in accordance
with the guidance relating to share-based payment. The amendment allowed the continued use, subject to specific criteria, of the simplified method in estimating the expected life of stock options granted after December 31, 2008. The Company did
not grant any employee stock options since then.

The fair values of the options granted under the TSMC 2002 Plan was not
reasonably estimable using appropriate valuation methodologies because the terms of such plans included a provision for a reduction in the exercise price in the event TSMC issues additional common shares or issues ADSs at a price lower than the
exercise price of a granted stock option. Accordingly, the expenses for the stock options granted under the TSMC 2002 Plan was determined using the variable accounting method. Under such method, the Company accounts for these stock options based on
their intrinsic value, remeasured at each reporting date through the date of exercise or other settlement.

Please refer to
Note 23 of the Consolidated Financial Statements for other general terms of TSMCs and Xintecs Employee Stock Option Plans, such as the maximum contractual term and the number of shares authorized for each stock option plan, as well as
the supplemental information such as outstanding options as of December 31, 2011.

The weighted average remaining
aggregate intrinsic value and contractual term of options under the foregoing plans as of December 31, 2011 were as follows:

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the
difference between TSMCs stock closing price on the last trading date of the year ended December 31, 2011 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, 2011.

The number of options expected to vest for the years
ended December 31, 2010 and 2011 was 1,061 thousand shares and nil, respectively.

Total intrinsic value of options
exercised in the years ended December 31, 2010 and 2011 was NT$412.3 million and NT$313.5 million, respectively. Total fair value of options vested, net of taxes, during the years ended December 31, 2010 and 2011 was NT$69.2 million and
NT$2.5 million, respectively.

As of December 31, 2011, all of the option plans were vested and the unrecognized
compensation cost related to stock-based compensation plans was nil.

| | e. | Uncertainty in income taxes
| | -- | ---------------------------

On
January 1, 2007, the Company adopted new guidance related to accounting for uncertainty in income taxes, which clarifies the accounting for uncertainty in income taxes by prescribing a more-likely-than-not threshold for financial statement
recognition and measurement of a tax position taken or expected to be taken in a tax return. This guidance also provides rules guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and
transition. As a result of the implementation of this guidance, the Company did not recognize any cumulative effect adjustment impacting retained earnings as of the beginning of fiscal year 2007. As of December 31, 2010 and 2011, there was no
material uncertain tax positions or unrecognized tax benefits identified by the Company. The Company does not expect there will be any significant change in this uncertain tax position or unrecognized tax benefits within 12 months of the reporting
date.



| | f. | Settlement income
| | -- | -----------------

Settlement
income of NT$1,464.9 million, NT$6,939.8 million and NT$947.3 million was recognized in the years ended December 31, 2009, 2010 and 2011, respectively, under the settlement agreement with Semiconductor Manufacturing International Corporation
(SMIC). The dispute settlement is not a component of the activities that constitute the Companys ongoing major or central operations and therefore is classified as non-operating income.

The Company recognized such settlement income on a cash basis due to the Companys serious doubt as to its collectability at the
time the settlement agreement was consummated. The Company continues to analyze the recognition of the remaining settlement income based on its collectability, and will evaluate SMICs reported financial condition, capital resources and
liquidity condition on a regular basis.



| | g. | Deconsolidation of GUC
| | -- | ----------------------

Since
July 2011, the Company ceased to have controlling interest in GUC and its subsidiaries due to the termination of a Shareholders Agreement; as a result, the Company no longer consolidates GUC. Under the deconsolidation accounting guidelines,
the investor's opening investment is recorded at fair value as of the date of deconsolidation. The difference between this fair value of the investment and the net carrying value is recognized as a gain or loss in earnings. During the third quarter
of 2011, the Company completed a valuation analysis to determine the initial fair value of its investment in GUC. In determining the fair value, as GUC is listed on TSE, the Company used the market approach by considering GUCs market price and
the Companys shareholding in GUC upon deconsolidation.

Based on the results of the valuation, the Company determined
that at the deconsolidation date the fair value of its investment in GUC was NT$5,369.2 million and recognized a non-cash gain of NT$ 4,304.1 million in non-operating income under U.S. GAAP for the year ended December 31, 2011.
