Forward-Looking Statements in This Annual Report May Not Be Accurate

Our disclosure and analysis in this annual report contain or incorporate by reference some forward-looking statements. Our forward-looking
statements contain information regarding, among other things, our financial condition, future expansion plans and business strategy. We have based these forward-looking statements on our current expectations and projections about future events. You
can identify these statements by the fact that they do not relate strictly to historical or current facts. Although we believe that these expectations and projections are reasonable, such forward-looking statements are inherently subject to risks,
uncertainties and assumptions about us, including, among other things:



| |  |  | the intensely competitive semiconductor and personal computer industries and markets;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | risks associated with international business activities;
| | - |  | --------------------------------------------------------



| |  |  | our dependence on key personnel;
| | - |  | --------------------------------



| |  |  | natural disasters, such as earthquakes and droughts, which are beyond our control;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | general economic and political conditions, including those related to the semiconductor and personal computer industries;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | possible disruptions in commercial activities caused by human-induced disasters, including terrorist activity and armed conflict, and outbreaks of contagious diseases, such as avian influenza which reduce end-user
purchases relative to expectations and orders;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | fluctuations in foreign currency exchange rates;
| | - |  | ------------------------------------------------



| |  |  | additional disclosures we make in our previous and future Form 20-F annual reports and Form 6-K periodic reports to the Securities and Exchange Commission, or the SEC; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | those other risks identified in Item 3. Key InformationD. Risk Factors of this annual report.
| | - |  | ------------------------------------------------------------------------------------------------

The words anticipate, believe, estimate, expect, intend, plan,
will, shall and similar expressions, as they relate to us, are intended to identify a number of these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements whether as a
result of new information, future events or otherwise. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this annual report might not occur and our actual results could differ materially from those
anticipated in these forward-looking statements.

A. Selected Financial Data

The selected consolidated financial data set forth below as of and for the years ended December 31, 2012 and 2013 have been derived from

Risks Relating to Our Financial Condition and Business

Any global systemic economic and financial crisis could negatively affect our business, results of operations, and financial condition

The systemic economic and financial crisis in 2008 and 2009 that affected global businesses including the banking and financial
sectors also had an impact on the semiconductor markets, resulting in sharp declines in demand for our semiconductor packaging and testing services from which we generate our revenues. The global economy has been slowly recovering since the end of
2009. However, the global economy is still uncertain and may deteriorate in the future. There were, and could be in the future, domino effects from the global markets turmoil on our business, including significant decreases in orders from our
customers, insolvency of key suppliers resulting in service delays, inability of customers to obtain credit to finance purchases of our services, customer insolvencies, weak consumer confidence, diminished consumer and business spending and asset
depreciation negatively impacting our operations. Any systemic economic or financial crisis could cause revenues for the semiconductor industry as a whole to decline dramatically and could materially and adversely affect our results of operations.

The cyclical nature of the semiconductor industry makes us particularly vulnerable to economic downturns and changes in the
semiconductor industry

Because our manufacturing services are, and will continue to be, dependent on the requirements of
semiconductor companies for independent testing and assembly services, any downturn in the highly cyclical semiconductor industry, caused by economic downturns or other reasons, may reduce demand for our manufacturing services and adversely affect
our results of operations. Variations in order levels from our customers and in service fee rates may result in volatility in our net operating revenues and earnings. The markets for semiconductors are also characterized by rapid technological
change, evolving industry standards and periods of heightened competition. If demand for semiconductor capacity does not keep pace with the growth of supply, or further declines, our manufacturing services would be subject to more intense
competition and our results of operations may suffer because of the resulting downward pricing pressure and capacity underutilization. Any increased competition may cause average selling prices of many of our semiconductor packages and testing
services to decrease significantly, which may lead to pressure on our gross margins and negatively affect our operating results. Future downturns in the semiconductor industry may be severe. In the event of any future downturn, our average selling
prices may decline without a corresponding decrease in our high fixed costs. This could lead to a decline in our profitability, which would seriously harm our manufacturing services.

Our operating results fluctuate significantly, which may affect the value of your investments

Our historical net operating revenues and results of operations have varied, at times significantly, from quarter to quarter. Our future net
operating revenues, gross profit and operating income may vary significantly due to a combination of factors. These factors include:



| |  |  | our ability to develop and implement new technologies. If we are unable to successfully implement new technologies in a timely manner, our operating results could suffer because we would allow our competitors to seize
the opportunities in developing new markets.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in our mix of manufacturing services or our customers preferences. When we discontinue or add manufacturing service or when our customers demand changes, our operating results usually fluctuate.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in capacity utilization. When capacity utilization is low, such as in times of market downturns, we may need to adjust our mix of manufacturing services to respond to changes in demand and to adjust our prices
sufficiently enough to maintain the level of our capacity utilization.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Moreover, the substrate packaging which uses
higher-cost raw materials has caused the costs of production for semiconductor packaging to rise significantly. If our revenues do not grow and we are unable to reduce our expenses, our profitability will suffer.

We do not have any significant backlog because our customers do not place purchase orders far in advance, which makes us vulnerable to
sudden changes in customer demand

Our customers generally do not place purchase orders far in advance, and our contracts with
major domestic customers do not generally require minimum purchase of our manufacturing services. In addition, our customers purchase orders have varied significantly from period to period because demand for their products is often volatile.
As a result, we do not typically operate with any significant backlog. The lack of a significant backlog makes it difficult for us to forecast our net operating revenues in future periods and causes our operating results to fluctuate from period to
period. Moreover, our expense levels are based in part on our expectations of future revenue and we may be unable to adjust costs in a timely manner to compensate for revenue shortfalls. We expect that in the future our net operating revenues in any
quarter will continue to be substantially dependent upon purchase orders received in that quarter. We cannot assure you that any of our customers will continue to place orders with us in the future at the same levels as in prior periods. We also
cannot assure you that our customers orders will be consistent with our expectations when we made or will make the necessary investments in raw materials, labor and equipment.

If we are unable to maintain a steady return to our former capacity utilization rates, our
profitability would be adversely affected

Our operations, in particular our bumping and testing operations have high fixed costs.
Our profitability is affected by the capacity utilization rates for our machinery and equipment. In periods of slow demand, we experience relatively low capacity utilization rates in our operations, which lead to reduced margins. We cannot assure
you that we will be able to maintain or surpass our past gross margin levels if we cannot consistently achieve or maintain relatively high capacity utilization rates. The factors affecting our capacity utilization in 2013 included:



| |  |  | the continued soft demand for personal computer products and peripherals resulting from after effects of the European debt crisis and macroeconomic uncertainty which the strong demand for cellular phone products could
not make up for; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the packaging technology migrating from wire bond to flip chip, which resulted in underutilization of existing wire bonders, as customers demanded flip chip packaging in place of wire bonding services.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Such uncontrollable factors caused diverse capacity utilization in our different manufacturing processes. The continuing
instability in demand has made it difficult to meet original planned weight in different services and sustain a high utilization rate. Any uncertainty in the semiconductor industry as a result of such events would harm our capacity utilization, and
as a result may adversely affect our profitability and results of operations in the future. Given the high fixed costs of our services, high capacity utilization allows us to maintain higher gross margins because it allows us to allocate fixed costs
over a greater number of units we package and test. Increases or decreases in capacity utilization rates will have a significant effect on our manufacturing services. Accordingly, our ability to enhance our gross margins will depend, in part, on our
ability to continue to increase our capacity utilization rates.

In order to increase or sustain our capacity utilization, we must:



| |  |  | ensure that our packaging and testing technologies meet our customers demands;
| | - |  | -------------------------------------------------------------------------------



| |  |  | install advanced equipment in anticipation of new business; and
| | - |  | ---------------------------------------------------------------



| |  |  | prevent disruption of operations caused by fire, accidents, mechanical and technical failures, expansion, introduction of new packages or relocation of equipment.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------

If demand for our manufacturing services does not meet our expectations, our capacity utilization would decrease and our profitability would
suffer.

We depend on a small number of customers for a substantial portion of our revenues and a loss of any one of these customers
would result in the loss of a significant portion of our revenues

We are dependent on a small group of customers for a
substantial portion of our manufacturing services. In 2012 and 2013, 57.0% and 60.0% of our net operating revenues, respectively, were derived from sales to our top ten customers. In 2013, our largest customer accounted for 8.3% of our net operating
revenues. We expect that we will continue to depend on a relatively limited number of customers for a significant portion of our net operating revenues because of the concentration of demand in the semiconductor industry for our manufacturing
services. Our ability to maintain close and satisfactory relationships with our customers is important to the ongoing success and profitability of our manufacturing services. Few of our customers are presently obligated to purchase packaging or
testing services or to provide us with forecasts of product purchases for any period. If any of our significant customers reduces, delays or cancels its orders to a significant degree, our manufacturing services would be harmed because each of these
customers accounts for a significant portion of our net operating revenues.

If capital resources required for our future expansion
plans are not available, we may be unable to successfully implement our services strategy

We have engaged in equipment and
facilities expansion in recent years to upgrade our technology and equipment. Our business growth in the future will continue to require substantial capital expenditures to fund such equipment and facilities expansions. We periodically review and
adjust our capital expenditure plans to address our expectation of demand for our services and prevailing industry trends. The growing demand for our manufacturing services has and will continue to require significant capital expenditures on
packaging technology and equipment. In making these planned capital expenditures, we may need to obtain additional capital. In addition, we may be unable to accurately estimate the timing and amount of our capital requirements, which depend on a
number of factors, including demand for our manufacturing services and availability of equipment and whether or when the market will recover. In addition, we cannot assure you that additional financing will be available on satisfactory terms to us,
or at all, when we require additional financing, which could have a material adverse effect on our business and results of operations.

If we cannot compete successfully in our industry, our current and potential customers
would likely decide not to use our manufacturing services, which would seriously harm our business

The independent semiconductor
packaging and testing industry is very competitive. We face substantial competition from established packaging and testing companies, including Advanced Semiconductor Engineering, Inc. (Taiwan), Amkor Technology Inc. (USA) and STATS ChipPAC Ltd.
(Singapore). We may face additional competition from new competitors in our industry in emerging countries, such as the Peoples Republic of China, or the P.R.C., where demand is expected to grow for our manufacturing services. To a lesser
extent, we also compete with the internal packaging and testing capabilities of our customers who have in-house packaging and testing capabilities. Some of our competitors have greater technology resources. Some of our competitors have greater
financial and other resources than we do, including established relationships with many large semiconductor companies which are our current or potential customers. These relationships and lengthy qualification periods required by most of our
potential customers may prevent us from securing new customers.

If the outsourcing trend for packaging and testing services does
not continue, we could lose a significant number of our current customers and we may be unable to implement our manufacturing services strategy plan in the future

We depend on outsourcing of packaging and testing services by fabless semiconductor companies and integrated device manufacturers. In recent
years, semiconductor companies have increasingly subcontracted parts of the semiconductor production process, including packaging and testing, to independent companies to reduce costs and shorten production cycles. However, we cannot assure you that
the outsourcing trend will continue. If integrated device manufacturers become dissatisfied with the services of independent semiconductor packaging and testing companies, they may return to utilizing in-house packaging and testing capabilities. A
reversal of, or slowdown in, the outsourcing trend would harm our business and make it difficult for us to implement our growth plan in the future.

The trend of adopting protectionist measures in certain countries, including the United States, could have a material adverse impact on
our results of operations and financial condition

Governments in the United States, China, Europe and certain other countries
have implemented fiscal and monetary programs to stimulate economic growth as a result of the recent economic downturn, and many of these programs include protectionist measures that encourage the use of domestic products and labor. If the
governments in the countries where our customers are located enact protectionist measures that encourage the use of domestic products and labor, demand for our services could be adversely affected. Recent policy developments by the governments in
China also suggest an increased unwillingness to allow international companies to invest in or acquire local businesses. Since some of our direct customers and other downstream customers in the supply chain are located in or have operations in the
countries where protectionist measures were adopted, such protectionist measures could have a material adverse effect on our business in the future.

Our production schedule may be delayed and our business may be adversely affected if we are unable to obtain raw materials from our
suppliers at acceptable prices, qualities and quantities

We must obtain sufficient quantities of raw materials at acceptable
prices in a timely manner. We source most of our raw materials, including critical materials, such as gold wire, substrates and lead-frames, from a limited group of suppliers. We purchase all of our materials on a purchase order basis at prevailing
market prices and have no long-term contracts with any of our suppliers. From time to time, suppliers have extended lead times or limited the supply of required materials to us because of supply capacity constraints during market upturns for the
semiconductor industry. Consequently, we have experienced from time to time difficulty in obtaining acceptable quantities of raw materials on a timely basis. In addition, from time to time, we may reject materials that do not meet our
specifications, resulting in declines in output or yield. We cannot assure you that we will be able to obtain in the future sufficient quantities of raw materials and other supplies of an acceptable quality. Our inability to obtain raw materials in
a timely and cost effective manner would cause us to delay our production and delivery schedules, which may result in the loss of our customers and revenues.

Gold wire is a substantial raw material to us. The spot price of gold fluctuates and may be unpredictable. The increase in the price of gold
wire will result in the decrease in our gross margin. To the extent we are not able to offset any increases in our raw material costs, our gross margins may be adversely impacted.

If we are unable to obtain equipment from our suppliers, we may be forced to delay any
future expansion plans

We need to purchase new packaging and testing equipment if we decide to expand our operations. From time
to time, increased demand for new equipment may cause lead times to extend beyond those normally required by equipment vendors. For example, in the past, increased demand for equipment caused some equipment suppliers to only partially satisfy our
equipment orders in the normal lead time frame during market upturns for the semiconductor industry. The unavailability of equipment or failures to deliver equipment could delay implementation of our future expansion plans and impair our ability to
meet customer orders. If we are unable to implement our future expansion plans or meet customer orders, we could lose potential and existing customers. Generally, we do not enter into binding equipment purchase agreements and we acquire our
equipment on a purchase order basis, which exposes us to substantial risks. For example, sudden changes in foreign currency exchange rates, particularly the U.S. dollar and Japanese yen, could result in increased prices for equipment purchased by
us, which could harm our results of operations.

If we are unable to manage our growth effectively, our expansion plans could be
jeopardized

We have in the past and again recently experienced growth in the scope and complexity of our operations and in the
number of our employees. This growth has strained our managerial, financial, manufacturing and other resources. In order to manage our future growth, we must continue to implement additional operating and financial controls and hire and train
additional personnel. We cannot assure you that we will be able to do so in the future, and our failure to do so could jeopardize our future expansion plans.

We depend on key management and the loss of any key management personnel may disrupt our manufacturing services

Our success depends upon the continued service of key senior management. Members of our senior management have served us for an average of
over ten years and have made substantial contributions to our growth. We do not have employment contracts with many of our senior management and none of our senior management is bound by any non-competition agreement. If we lose the services of key
senior management we would be unable to find and integrate replacement personnel, which could adversely affect our services expansion.

We depend on our technical personnel and the inability to attract and retain them would jeopardize our operations and future expansion
plans

Our business depends on technology and, accordingly, our success depends on our ability to attract, retain and motivate
highly skilled employees, particularly engineering and technical personnel. Without sufficient numbers of skilled employees, our operations would suffer, resulting in deteriorating ability to solve operating and other issues in a timely and
effective manner. Competition for qualified engineering and technical employees in Taiwan is intense and replacement of qualified employees is difficult. If we are unable to attract, retain and motivate our technical personnel, our operations would
be jeopardized and our operating efficiency would deteriorate.

Our failure to comply with environmental regulations or to defend
against environmental claims could expose us to serious liabilities

The semiconductor packaging and testing processes produce
wastewater, industrial waste (liquid waste and solid waste) and flue gas, which are regulated by the government. For example, wastewater is produced when silicon wafers are diced into chips using diamond saws and cooled with running water.
Wastewater is also produced when lead-frames are plated with solder and cleansed with water after wafer chips are bonded onto them and capsulated by mold resin. Environmental claims or the failure to comply with any environmental regulations could
result in damages or fines against us or suspension of production. We may be required by new regulations to acquire costly equipment or to incur other significant expenses. If we fail to control the use of hazardous substances, we could incur future
liabilities, including clean-up costs.

We and our customers and suppliers are vulnerable to natural disasters and other events
beyond our control, the occurrence of which may seriously harm our manufacturing services

Our operations and those of our
customers and suppliers are particularly vulnerable to fires, earthquakes, typhoons, droughts, floods, power losses, and similar events. Disruptions or delays in our supply chain may result in shortages of components we utilize which may in turn
affect our ability to successfully perform our semiconductor packaging and testing services. Any failure on our part to provide our services to customers may have an adverse effect on our financial condition and results of operations.

We cannot guarantee that future natural disasters will not cause material damage to our facilities or property, including work in progress, or
cause significant business interruptions. Although we maintain property and business interruption insurance for such risks, there is no guarantee that future damages or business loss from natural disasters will be covered by such insurance, that we
will be able to collect from our insurance carriers, should we choose to claim under our insurance policies, or that such coverage will be sufficient.

##### Table of Contents

In addition, the production facilities of many of our suppliers and customers providers of
complementary semiconductor manufacturing services, including foundries, are located in Taiwan. If our customers are affected, it could result in a decline in the demand for our testing and assembly services. If our suppliers and providers of
complementary semiconductor manufacturing services are affected, our production schedule could be interrupted or delayed. As a result, a major earthquake, natural disaster or other disruptive event in Taiwan could severely disrupt the normal
operation of business and have an adverse effect on our financial condition and results of operations.

Climate change, other
environmental concerns and green initiatives present commercial challenges, economic risks and physical risks that could harm our results of operations 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 would request us to
exceed any standard(s) set for environmentally compliant products and services. 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. Customers may request us to provide information on a particular products carbon footprint, which is expressed in terms of the carbon dioxide emission from our manufacture of a product. If
we are unable to provide the requested information to customers, or if we provide a higher carbon footprint figure than customers expect, we may also lose market share, which may have an adverse effect on our financial condition and results of
operations.

Further, energy costs in general could increase significantly due to climate change regulations. Therefore, our energy costs
may increase significantly if utility or power companies pass on their costs, fully or partially, such as those associated with carbon taxes, emission cap and carbon credit trading programs.

In addition, more frequent droughts and floods, extreme weather conditions and rising sea levels could occur due to climate change. The impact
of such changes could be significant as our facilities are located in Taiwan, which is an island. For example, transportation suspension caused by extreme weather conditions could harm the delivery of our supplies and the distribution of our
products. We cannot predict the economic impact, if any, of disasters or climate change.

Disruptions in the international trading
environment may seriously decrease our international sales

A substantial portion of our net operating revenues is derived from
sales to customers located outside of Taiwan. In 2012 and 2013, sales to our overseas customers accounted for 78.7% and 78.1%, respectively, of our net operating revenues. We expect sales to customers outside of Taiwan to continue to represent a
significant portion of our net operating revenues. As a result, our manufacturing services will continue to be vulnerable to disruptions in the international trading environment, including adverse changes in foreign government regulations, political
unrest and international economic downturns.

These disruptions in the international trading environment affect the demand for our
manufacturing services and change the terms upon which we provide our manufacturing services overseas, which could seriously decrease our international sales.

Compliance with laws relating to conflict minerals may increase our costs and lead to reputational challenges.

The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and accountability concerning the
supply of certain minerals originating from the Democratic Republic of Congo, or the DRC, and adjoining countries that are believed to be benefiting armed groups. As a result, the SEC has adopted due diligence, disclosure and reporting requirements
for companies which manufacture products that include components containing gold, columbite-tantalite (tantalum), cassiterite (tin) and wolframite (tungsten), regardless of whether the minerals are actually mined in the DRC or adjoining countries.
Our first report under these rules will be due on May 31, 2014. In order to comply with the rules and regulations promulgated by the SEC, we will verify all relevant factual data with our vendors in accordance with the industry accepted
procedures and the Electronic Industry Citizenship Coalition and Global e-Sustainability conflict minerals reporting template, and file the required reports annually. Although we expect that we and our vendors will be able to comply with the
requirements, there can be no guarantee that we will be able to gather all the information required. In addition, such regulations could decrease the availability and increase the prices of components used in our products, particularly if we choose
(or are required by our customers) to source such components from different suppliers than we use now. Furthermore, as our supply chain is complex, we expect that the compliance process will be both time-consuming and costly. We may face
reputational challenges if we are unable to timely verify the origins of minerals contained in the components included in our products, or if our due diligence process reveals that materials we source originate in the DRC or adjoining countries and
benefit armed groups.

Similarly, many countries are considering regulations concerning disclosure and enforcement of human rights within
supply chains. Although our own operations comply with the employment and employee rights requirements under the laws of the countries where we have operations, such proposals extend to the operations of suppliers, wherever they may be located.
While we require our suppliers and/or our supply chain to abide by the laws and/or requirements of being conflict free, and we believe our suppliers comply with applicable human rights requirements, there can be no guarantee that they will continue
to do so, or that we will be able to obtain the necessary information on their activities to comply with whatever future requirements may be enacted.

Risks Relating to Our Technologies

If we cannot respond to rapid technology changes in the semiconductor packaging and testing industry, our profitability will suffer

The semiconductor packaging and testing industry is characterized by rapid increases in the diversity and complexity of
semiconductor packaging and testing services. As a result, we expect that we will need to continue to develop and offer more advanced packaging and testing processes in order to respond to our customers requirements as industry conditions
change. Developing and maintaining advanced packaging and testing processes requires significant research and development and capital expenditures.

In addition, advances in technology typically lead to rapid and significant price erosion and decreased margins for older manufacturing
services and may cause our current manufacturing services to become less competitive. Our failure to develop or obtain advanced packaging and testing technologies will materially and adversely affect our mix of manufacturing services and would harm
our profitability.

If we are unable to successfully perform manufacturing services within the acceptable range of precision, we
will not be able to achieve satisfactory production yields and our results of operations will suffer

The semiconductor packaging
and testing processes are complex and involve a number of precise steps. Defective packaging and testing can result from a number of factors, including:



| |  |  | the level of contaminants in the manufacturing environment;
| | - |  | -----------------------------------------------------------



| |  |  | human error;
| | - |  | ------------



| |  |  | equipment malfunction;
| | - |  | ----------------------



| |  |  | incorrect process condition setting;
| | - |  | ------------------------------------



| |  |  | use of defective raw materials; and
| | - |  | -----------------------------------



| |  |  | inadequate sample testing.
| | - |  | --------------------------

From time to time, we expect to experience lower than anticipated
production yields as a result of the above factors, particularly in connection with the expansion of our capacity or change in our processing methods. In addition, our yield provided by new manufacturing services will be lower than average as we
develop the necessary expertise and experience to perform those manufacturing services. If we fail to maintain high quality production standards, our reputation may suffer and our customers may cancel their orders or ask for discount.

We rely on technology provided by third parties

We rely on certain technologies that we have obtained through alliances or licenses. For example, we have licensed from Freescale
Semiconductor Inc., or Freescale, formerly part of Motorola, Inc., or Motorola, the technology for ball grid array. We make royalty payments to Freescale and have the license to use this technology until December 2015. We implement new package
technologies by entering into technology alliances and by licensing package technologies from certain technology companies. There can be no assurance that third parties will continue to license advanced technologies to us on terms satisfactory or
acceptable to us after these licensing agreements expire, or at all. In the event that we are unable to license such advanced technologies from the third parties, we may be required to develop designed around technologies internally. There can be no
assurance that we will be able to develop such technologies internally.

Disputes over intellectual property rights could be costly and could deprive us of
technologies to stay competitive

We may suffer legal liabilities and damages if we infringe on the proprietary rights of others
or incur costs resulting from legal claims and adverse proceedings against us. Despite this, we have no means of knowing what patent applications have been filed in the United States or elsewhere until they are granted or published. The
semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights, although such litigations in the semiconductor packaging and testing industry tend to not be so prevalent. If any third party
were to make valid intellectual property infringement claims against us or our customers, we could be required to:



| |  |  | discontinue using disputed process technologies which would prevent us from offering some of our packaging and testing services;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | pay substantial monetary damages;
| | - |  | ---------------------------------



| |  |  | seek to develop non-infringing technologies, which may not be feasible; or
| | - |  | --------------------------------------------------------------------------



| |  |  | seek to acquire licenses to the infringed technology, which may not be available on commercially reasonable terms, if at all.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------

We could also be required to expend substantial resources to defend any claim alleging our infringement of patents or other intellectual
property rights. If we fail to obtain necessary licenses or if litigation relating to patent infringement or other intellectual property matters occurs, it could seriously harm our company.

In addition, we have acquired patents and trademarks to protect some of our proprietary technologies and manufacturing services. We cannot
assure you, however, that these measures will provide meaningful protection of our intellectual property. For example, our competitors may be able to develop similar or superior manufacturing service technology, or we may not successfully protect or
enforce our intellectual property rights.

On March 1, 2006, we were informed of a lawsuit, or the California Litigation, brought by
Tessera Inc., or Tessera, in the United States District Court for the Northern District of California against us, our subsidiary Siliconware U.S.A., Inc. and five other semiconductor companies and their subsidiaries. Tessera alleged that some of our
packaging services infringe patents owned by Tessera and that we have breached license agreements with Tessera. In April 2013, we entered into a settlement agreement with Tessera. The settlement amount of US$30 million was recognized in our 2013
first quarter financial report. For more information, see Item 4. Information on the Company  B. Business Overview  Litigation.

Political and Economic Risks

We face substantial political risks associated with doing business in Taiwan, particularly due to the tense relationship between the
Republic of China, or the R.O.C., and the P.R.C.

Our principal executive offices and all of our assets are substantially located
in Taiwan. Accordingly, our services, financial condition and results of operations and the market price of our common shares and the ADSs may be affected by changes in R.O.C. governmental policies, taxation, inflation or interest rates and by
social instability and diplomatic and social developments in or affecting Taiwan which are outside of our control. Taiwan has a unique international political status. Since 1949, Taiwan and the Chinese mainland have been separately governed. The
P.R.C. claims that it is the sole government in China and that Taiwan is part of China. Although significant economic and cultural relations have been established during recent years between the R.O.C. and the P.R.C., relations have often been
strained. The P.R.C. government has refused to renounce the use of military force to gain control over Taiwan and, in March 2005, further passed an Anti-Secession Law that authorizes non-peaceful means and other necessary measures should Taiwan move
to gain independence from the P.R.C. Past developments in relations between the R.O.C. and the P.R.C. have on occasion depressed the market prices of the securities of companies in the R.O.C. The R.O.C. also maintains important trade relations with
the U.S., which has sometimes led to increased friction between the U.S. and the P.R.C. Any deterioration in relations among the U.S., the R.O.C. and the P.R.C. and other factors affecting military, political or economic conditions in Taiwan could
materially and adversely affect our financial condition and results of operations, as well as the market price and the liquidity of our securities.

##### Table of Contents

The trading price of our American Depositary Shares may be adversely affected by the
general activities of the Taiwan Stock Exchange and U.S. stock exchanges, the trading price of our shares, fluctuations in interest rates and the economic performance of Taiwan and global markets

Our shares are listed on the Taiwan Stock Exchange. The trading price of our ADSs may be affected by the trading price of our shares on the
Taiwan Stock Exchange. The Taiwan Stock Exchange is a smaller market and, more volatile than the securities markets in the United States and a number of European countries. The Taiwan Stock Exchange has experienced substantial fluctuations in the
prices and volumes of sales of listed securities, and there are currently limits on the range of daily price movements on the Taiwan Stock Exchange. During 2013, the Taiwan Stock Exchange Index peaked at 8,623.43 on December 30 and reached a
low of 7,616.64 on January 17. From January 1, 2013 to December 31, 2013, daily closing values of our shares ranged from NT$30.2 per share to NT$39.0 per share. The Taiwan Stock Exchange is particularly volatile during times of
political instability, including when relations between Taiwan and the P.R.C. are strained. Moreover, the Taiwan Stock Exchange has experienced problems including market manipulation, insider trading and settlement defaults. The recurrence of these
or similar problems could decrease the market price and liquidity of our shares and ADSs.

The market price of the ADSs may also be
affected by general trading activities on the U.S. stock exchanges, which have experienced significant price volatility with respect to shares of technology companies. Fluctuations in interest rates and other general economic conditions, such as
recession and economic downturns caused by the debt crisis, high energy costs and other concerns, in Taiwan and other countries where our products are sold may also have an effect on the market price of our ADSs. Daily closing values of our ADSs
ranged from US$1.88 to US$12.54 between June 7, 2000, the date on which our ADSs were listed on NASDAQ National Market, or NASDAQ, and December 31, 2013. Over the same period, the NASDAQ Composite Index ranged from 1,114.11 to 4,274.67.

Currency fluctuations could increase our costs relative to our revenues, which could adversely affect our profitability

Volatility in foreign exchange rates may have a material effect on our business. We are affected by fluctuations in exchange
rates among the U.S. dollar, the Japanese Yen, the NT dollar and other currencies. Some of our net operating revenues are denominated in currencies other than NT dollars, such as U.S. dollars, while more than half of our costs of direct labor, raw
materials and overhead are incurred in NT dollars. Therefore, any significant fluctuation in exchange rates could be harmful to our financial condition. In 2013, the foreign exchange rate between the U.S. dollar and the NT dollar has ranged from a
high of NT$30.03 per US$1.00 to a low of NT$29.42 per US$1.00. Fluctuations in the exchange rate between the U.S. dollar and the NT dollar will also affect the U.S. dollar value of the ADSs and the U.S. dollar value of any cash dividends we pay,
which could have a corresponding effect on the market price of the ADSs.

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

Any
future outbreak of contagious diseases, such as severe acute respiratory syndrome or H7N9 avian influenza, may affect our ability to maintain sufficient operating staff and services, and may generally disrupt our operations. An outbreak of influenza
on the human population could result in a widespread health crisis which could adversely affect the economies and financial markets of many countries, particularly in Asia. There is no guarantee that any future outbreak of contagious diseases or the
measures taken by various countries of the world in response to a future outbreak of contagious diseases will not seriously interrupt our operations or those of our suppliers and customers. If any of our employees is suspected of having contracted
any contagious disease, we may, under certain circumstances, be required to quarantine such employees and the affected areas of our premises. As a result, we may have to temporarily suspend part or all of our operations. Furthermore, any future
outbreak may restrict the level of economic activity in affected regions, including Taiwan, which may also adversely affect our manufacturing services and prospects. As a result, we cannot assure you that any future outbreak of contagious diseases
would not have a material adverse effect on our financial condition and results of operations.

Our future tax obligations may
adversely affect our profitability

The Amendments of the Income Tax Law promulgated on May 27, 2009 reduced the
income tax rate for profit-seeking enterprises from 25% to 20%, which is effective from January 1, 2010. However, the corporate income tax rate is further reduced from 20% to 17%, which is effective from January 1, 2010, based on the
Amendments of the Income Tax Law promulgated on June 15, 2010. In addition, according to theIndustrial Innovation Act issued on May 12, 2010, the deductible rate of investment tax credit for qualifying research and
development expenditures was reduced from 30% to 15% starting January 1, 2010. Any reduction or elimination of our preferential tax benefits would increase our tax obligations and could have an adverse effect on our results of operations.

Risks Relating to the P.R.C.

Our operations in the P.R.C. may expose us to political, regulatory, economic and foreign investment risks in the P.R.C.

Some of our customers and foreign competitors have expanded their operations to the P.R.C. In order to remain competitive and to position
ourselves to gain market share, we established a subsidiary named Siliconware Technology (Suzhou) Limited, or Siliconware Suzhou, in 2002, which currently is primarily engaged in the assembly and testing service. Prior to 1978, the P.R.C. operated
under a central economic planning system. All production and economic activities in the country were governed by the economic goals set out in the five-year plans and annual plans adopted by central authorities. Since 1978, the P.R.C. government has
permitted foreign investment and implemented economic reforms, gradually changing from a planned economy to a market-oriented economy. However, many of the reforms and economic policies adopted or to be adopted by the P.R.C. government are
unprecedented or experimental in nature and may have unforeseen results, which may have an adverse effect on enterprises with substantial business in the P.R.C., including us.

Since 1979, many laws and regulations dealing with general economic matters or particular economic activities have been promulgated in the
P.R.C. However, enforcement of existing laws and regulations may be uncertain and sporadic and implementation and interpretation thereof may be inconsistent. The P.R.C. judiciary is relatively inexperienced and underdeveloped in enforcing the laws
and regulations that currently exist, leading to a degree of uncertainty as to the outcome of any litigation. Further, it may be difficult to obtain swift and equitable enforcement or to obtain enforcement of a judgment by a court of another
jurisdiction. The P.R.C.s legal system is based on written statutes and, therefore, decided legal cases do not have binding legal effect, although they are often followed by judges as guidance. The introduction of new P.R.C. laws and
regulations and the interpretation of existing laws and regulations may be subject to policy changes reflecting domestic political or social changes. As the P.R.C. legal system develops, there can be no assurance that changes in such legislation or
interpretation thereof would not have a material adverse effect on our business, financial condition, results of our operations and future prospects.

Changes in P.R.C. foreign exchange regulations may adversely affect our results of operations and financial condition

The exchange rate between the Renminbi and the U.S. dollar and other foreign currencies is affected by, among other things, changes in
Chinas political and economic conditions. On July 21, 2005, the P.R.C. government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new policy, the Renminbi is permitted to fluctuate within a
narrow and managed band against a basket of foreign currencies. Since July 2008, however, the Renminbi has traded within a narrow range against the US dollar. On June 20, 2010, the Peoples Bank of China announced that the P.R.C.
government would further reform the Renminbi exchange rate regime and increase the flexibility of the exchange rate. In April 2012, the Peoples Bank of China announced that it would expand the floating range of the trading price of the
Renminbi against the U.S. dollar from 0.5% to 1.0%. In March 2014, the Peoples Bank of China announced that it would further expand the floating range of the trading price of the Renminbi against the U.S. dollar from 1.0% to 2.0%. The Renminbi
appreciated 26.9% against the U.S. dollar between July 21, 2005 and December 31, 2013. Although it is difficult to predict how Renminbi exchange rates may change going forward, a more flexible currency policy could result in a further and
more significant appreciation of Renminbi against the U.S. dollar. Any increase in the value of the Renminbi might adversely affect the growth of the Chinese economy, increase our operating expenses as well as the competitiveness of various
industries in China, including our industry, which could in turn affect our financial condition and results of operations.

An
increase in labor costs may undermine our cost competitiveness, erode our profitability and thus affect our financial performance

We, along with our suppliers and customers, rely on our workers in our various manufacturing facilities. Labor costs in the various countries
where we have manufacturing facilities may increase as those countries develop and have populations that are more affluent. For example, as factory workers have sought higher wages in China, we have been adjusting the wages of our workers in line
with market conditions. In addition, increased labor costs of our suppliers could be passed along to us.

These increases in labor cost
may undermine our cost competitiveness, erode our profitability and materially harm our business, financial condition and results of operations.

Risks Related to Ownership of Our Shares or ADSs

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

The ability to deposit shares into our ADS program is restricted by R.O.C. law. Under current R.O.C. law, no person or entity, including you
and us, may deposit shares into our ADS program without specific approval of the R.O.C. Securities and Futures Bureau, or R.O.C. SFB except for the deposit of the shares into our ADS program and for the issuance of additional ADSs in connection
with:



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



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



| |  |  | if permitted under the deposit agreement and the custody agreement, purchases of our shares in the domestic market in Taiwan by the investor directly or through the depositary or the surrender of shares under the
possession of investors and then delivery of such shares to the custodian for deposit into our ADS program, subject to the following conditions: (i) the depositary may accept deposit of those shares and issue the corresponding number of ADSs
with regard to such deposit only if the total number of ADSs outstanding after the deposit does not exceed the number of ADSs previously approved by R.O.C. SFB, plus any ADSs issued pursuant to the events described in the above two bullet points;
and (ii) this deposit may only be made to the extent previously issued ADSs have been cancelled.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result of the
limited ability to deposit shares into our ADS program, the prevailing market price of our ADSs on NASDAQ, may differ from the prevailing market price of the equivalent number of our shares on the Taiwan Stock Exchange.

Holders of our ADSs will not have the same proposal or voting rights as the holders of our shares, which may affect the value of your
investment

Due to the amendment to the R.O.C. Company Act and the amendment made to our articles of incorporation accordingly,
except for treasury shares, each common share is generally entitled to one vote and no voting discount will be applied. However, except as described in this annual report and in the deposit agreement, holders of our ADSs will not be able to exercise
voting rights attaching to the shares evidenced by our ADSs on an individual basis. Holders of our ADSs will appoint the depositary or its nominee as their representative to exercise the voting rights attaching to the shares represented by the ADSs.
The voting rights attaching to the shares evidenced by our ADSs must be exercised as to all matters brought to a vote of shareholders collectively in the same manner.

Moreover, holders of the ADSs do not have individual rights to propose any matter for shareholders votes at our shareholders
meetings. However, holders of at least 51% of the ADSs outstanding at the relevant record date may request the depositary to submit to us one proposal per year for consideration at our annual ordinary shareholders meeting, provided that such
proposal meets certain submission criteria and limitations, including the language and the length of the proposal, the time of submission, the required certification or undertakings, and the attendance at the annual ordinary shareholders
meeting. A qualified proposal so submitted by the depositary will still be subject to review by our board of directors and there is no assurance that the proposal will be accepted by our board of directors for inclusion in the agenda of our annual
ordinary shareholders meeting. Furthermore, if we determine, at our discretion, that the proposal submitted by the depositary does not qualify, we have no obligation to notify the depositary or to allow the depositary to modify such proposal.

Furthermore, if holders of at least 51% of the ADSs outstanding at the relevant record date instruct the depositary to vote in the same
manner regarding a resolution, including election of directors, the depositary will appoint our Chairman, or his designee, to represent the ADS holders at the shareholders meetings and to vote the shares represented by the ADSs outstanding in
the manner so instructed. If by the relevant record date the depositary has not received instructions from holders of ADSs holding at least 51% of the ADSs to vote in the same manner for any resolution, then the holders will be deemed to have
instructed the depositary to authorize and appoint our Chairman, or his designee, to vote all the shares represented by ADSs at his sole discretion, which may not be in your interest.

The rights of holders of our ADSs to participate in our rights offerings may be limited, which may cause dilution to their holdings

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. Under the deposit
agreement, the depositary will not offer those rights to ADS holders unless both the rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act or exempt from registration under the
Securities Act. We are under no obligation to file a registration statement with respect to any such rights or underlying securities or to endeavor to cause such a registration statement to be declared effective. Accordingly, holders of our ADSs may
be unable to participate in our rights offerings and may experience dilution in their holdings.

Our public shareholders may have more difficulty protecting their interests than they would
as shareholders of a U.S. corporation

Our corporate affairs are governed by our articles of incorporation and by the laws
governing R.O.C. corporations. The rights of our shareholders to bring shareholders suits against us or our board of directors under R.O.C. law are much more limited than those of the shareholders of U.S. corporations. Therefore, our public
shareholders may have more difficulty protecting their interests in connection with actions taken by our management, members of our board of directors or controlling shareholders than they would as shareholders of a U.S. corporation. Please refer to
Item 10. Additional InformationB. Memorandum and Articles of Association included elsewhere in this annual report for a detailed discussion of the rights of our shareholders to bring legal actions against us or our directors under
R.O.C. law.

Holders of our ADSs will be required to appoint several local agents in Taiwan if they withdraw shares from our ADS
program and become our shareholders, which may make ownership burdensome

Non-R.O.C. persons wishing to withdraw shares
represented by their ADSs from our ADS program and hold our shares represented by those ADSs are required to appoint a local agent or representative with qualifications set forth by the R.O.C. SFB to open a securities trading account with a local
brokerage firm, pay R.O.C. taxes, remit funds and exercise shareholders rights. In addition, the withdrawing holders are also required to appoint a custodian bank with qualifications set forth by the Ministry of Finance to hold the securities
in safekeeping, make confirmations, settle trades and report all relevant information. Without making this appointment and opening of the accounts, the withdrawing holders would not be able to subsequently sell our shares withdrawn from a depositary
receipt facility on the Taiwan Stock Exchange. Under R.O.C. law and regulations, citizens of the P.R.C. are not permitted to hold our shares or withdraw shares represented by ADSs from our ADS program.

You may not be able to enforce a judgment of a foreign court in the R.O.C.

We are a company limited by shares incorporated under the R.O.C. Company Act. Most of our assets and most of our directors, supervisors and
executive officers and experts named in the registration statement are located in Taiwan. As a result, it may be difficult for you to enforce judgments obtained outside Taiwan upon us or such persons in Taiwan. Any judgment obtained against us in
any court outside the R.O.C. arising out of or relating to the ADSs will not be enforced by R.O.C. courts if any of the following situations shall apply to such final judgment:



| |  |  | the court rendering the judgment does not have jurisdiction over the subject matter according to R.O.C. law;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | the judgment or the court procedures resulting in the judgment is contrary to the public order or good morals of the R.O.C.;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | the judgment was rendered by default, except where the summons or order necessary for the commencement of the action was duly served on us within the jurisdiction of the court rendering the judgment within a reasonable
period of time and in accordance with the laws and regulations of such jurisdiction, or with judicial assistance of the R.O.C.; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the judgments of R.O.C. courts are not recognized and enforceable in the jurisdiction of the court rendering the judgment on a reciprocal basis.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------

We may become a passive foreign investment company, or PFIC, which could result in adverse U.S. tax consequences to U.S. investors

Based upon the past and projected composition of our income and valuation of our assets, including goodwill, we believe we were
not a passive foreign investment company, or PFIC, for 2013, and do not expect to become one in the future, although there can be no assurance in this regard. If, however, we were or were to become a PFIC, such characterization could result in
adverse U.S. tax consequences to you if you are a U.S. investor. For example, if we are a PFIC, our U.S. investors will become subject to increased tax liabilities under U.S. tax laws and regulations and will become subject to burdensome reporting
requirements. The determination of whether or not we are a PFIC is made on an annual basis and will depend on the composition of our income and assets from time to time. Specifically, we will be classified as a PFIC for U.S. tax purposes if either:
(i) 75% or more of our gross income in a taxable year is passive income, or (ii) the average percentage of our assets by value in a taxable year which produce or are held for the production of passive income (which includes cash) is at
least 50%. The calculation of the value of our assets will be based, in part, on the quarterly market value of our shares, which is subject to change. We cannot assure you that we will not be a PFIC for 2013 or any future taxable year. See

Because our services are, and will
continue to be, dependent on the requirements of semiconductor companies for independent testing and assembly services, any downturn in the highly cyclical semiconductor industry may reduce demand for our services and adversely affect our results of
operations. Therefore, our operations are subject to seasonal effects.

Our Packaging Services

We offer a broad range of package formats designed to provide our customers with a full array of packaging solutions. The packaging solutions
we currently offer to our customers include substrate packages, which include ball grid array and system in packages (incorporating multiple semiconductor chips) and flip-chip ball grid array packages, together with lead-frame packages.
Semiconductor packaging serves to protect semiconductor chips, to facilitate their integration into electronic systems and to enable the dissipation of heat produced by the final product. The packaging process begins with dicing patterned silicon
wafers into separated dies. Each die is attached to a substrate or lead-frame interposer with gold, copper or silver wires or bumps. Each chip is then encapsulated, generally by molding compound or underfilled in a flip chip ball grid array.

Semiconductor packages have evolved from lead-frame packages to substrate packages in response to the increasing demands of todays
high-performance electronics products. The differentiating characteristics of these packages include:



| |  |  | the size of the package;
| | - |  | ------------------------



| |  |  | the number of electrical connections the package can support; and
| | - |  | -----------------------------------------------------------------



| |  |  | the thermal and electrical requirements of the package.
| | - |  | -------------------------------------------------------

As modern applications for
semiconductor devices require smaller chips, the size of packages has also decreased. In leading-edge packages, the size of the package is miniaturized to just slightly larger than the size of the individual chip itself known as chip scale packages.

As semiconductor devices increase in complexity, the number of required electrical connections also increases. Our lead-frame packaging
has electrical connections from the semiconductor device to the electronic product through leads on the perimeter of the package. Our substrate packaging has balls on the bottom of the package that create the electrical connections with the
electronic system and can support larger numbers of electrical connections.

New methods of packaging have also enhanced the thermal and
electrical characteristics of semiconductor packages to meet the high-bandwidth, high-speed and high-power demands of modern semiconductor devices. Flip-chip packages enable direct interconnection from the chip to the substrate. Electrical
connection is first deposited on one side of a chip; then, the chip is flipped onto the substrate. Flip-chip technology eliminates the need for wire bonding and provides superior electrical performance. Chip scale packages have been designed for
devices which require reduced height, board space and weight by reducing the size of the package to be only slightly larger than the size of the die and are ideally suited for the latest generation of wireless and consumer electronics. System in
packages allow for the combination of multiple chips into a single package, enabling increased application functionality while miniaturizing overall size.

We price our packaging on a per unit basis, taking into account the complexity of the manufacturing required, the prevailing market
conditions, the order size, the strength and history of our relationship with the customer and our capacity utilization at the time.

In
order to reduce the impact from fluctuations in the price of gold wire, we have also been improving our manufacturing process to reduce the diameters of the gold wire used. In addition, we have developed and currently offer copper wire and silver
wire bonding processes to replace conventional processes based on gold wire. Copper wire and silver wire bonding processes have gained popularity recently due to the fact that copper and silver prices do not fluctuate as widely as gold prices.
Presently, copper wire and silver wire bonding is running at a high growth stage of production for lead-frame and substrate packaging.

Substrate Packages

This category generally employs the ball grid array design, which utilizes a laminated substrate rather than a lead-frame and places the
electrical connections on the bottom of the package rather than around the perimeter.

##### Table of Contents

The ball grid array format was developed to address the need for higher lead counts required by
advanced semiconductor devices. Benefits of ball grid array packaging over leaded packaging include:



| |  |  | smaller size;
| | - |  | -------------



| |  |  | greater pin count;
| | - |  | ------------------



| |  |  | greater reliability;
| | - |  | --------------------



| |  |  | better electrical signal integrity; and
| | - |  | ---------------------------------------



| |  |  | easier attachment to a printed circuit board.
| | - |  | ---------------------------------------------

As the number of leads surrounding the package
increased, the proximity of the leads to one another became closer in an attempt to maintain the size of the package. The close proximity of one lead to another resulted in electrical shorting problems, and required the development of increasingly
sophisticated and expensive techniques for producing circuit boards to accommodate the high number of leads.

The ball grid array format
solved this problem by effectively creating leads on the bottom of the package in the form of solder balls. These balls can be evenly distributed across the entire bottom surface of the package, allowing greater distance between the individual
leads. For the highest lead count devices, the ball grid array configuration can be manufactured less expensively and requires less delicate handling at installation.

To address the electronics market demand for higher frequency, higher input/output and better thermal performance, we have made efforts to
develop high value-added advanced packaging technologies, such as flip-chip and wafer bumping technologies. In addition to the development of the 8-inch wafer bumping technology, in order to meet the trend of wafer size moving to 12-inch from
8-inch, we successfully established the first 12-inch wafer bumping technology in the world. Flip-chip ball grid array is a high-end, high-growth packaging technology typically used in advanced semiconductor products such as microprocessor units,
micro peripherals, field programmable gate arrays and application specific integrated circuits. The flip-chip technology enables direct interconnection from the chip to the substrate, eliminates the need for wire bonding and provides superior
electrical performance. We have also developed thin and small package, or CSPs, on flexible or rigid substrates as well as lead-frames, which are suitable for the portable consumer market. Furthermore, we have developed module packages, with
multiple chips integrated into one package, in order to meet the growing demand for System-in-Package, or SiP, for applications in personal computers, communications devices and consumer products.

Lead-Frame Packages

Lead-frame packages are characterized by a semiconductor chip encapsulated in a plastic molding compound with metal leads on the perimeter.
This package category has evolved from a design where the leads are plugged into holes on the circuit board to a design where the leads are soldered to the surface of the circuit board. Lead-frame packages are divided into two general types of
packages: quad flat packages and small outline packages.

To satisfy the demand for miniaturization of portable electronic products, we
are developing increasingly smaller versions of lead-frame packages to keep pace with continually shrinking semiconductor device sizes. Our advanced lead-frame packages are similar in design to our older lead-frame packages. However, our advanced
lead-frame packages generally are thinner and smaller, have more leads and have advanced thermal and electrical characteristics. As a result of continued development of manufacturing service technology, we offer lead-frame packaging with a wide
range of lead counts and body sizes to satisfy variations in the size of customers semiconductor devices.

Testing and Other
Services

Semiconductor testing measures and ensures the performance, functionality and reliability of a packaged semiconductor
device. Testing semiconductor devices requires significant technical expertise and knowledge of the specific applications and functions of the device under testing. In addition to maintaining different types of advanced testing equipment which
enable us to test a variety of semiconductor device functions, we work closely with our customers to develop and convert programs to test particular semiconductor products on multiple equipment platforms effectively. The cost of any specific test is
dependent on the test time (usually measured in seconds) required to run a test which varies depending on the complexity of the semiconductor device and the customers specification with the percentage of fault coverage.

We also provide a variety of testing services as the following:

Wafer Probing. Wafer probing is the step immediately before packaging of integrated circuits and involves sorting the processed wafer
for defects to ensure that it meets customer acceptance criteria. Integrated circuits on an accepted wafer are then individually inspected visually under microscopes before packaging and final testing.

##### Table of Contents

Final Testing. We provide final testing services for a wide variety of logic and mixed
signal and RF integrated circuit packages and other integrated circuit packages, including complex and high-performance integrated circuits, as well as lower-performance ones. High-performance products include personal computer-related components
such as CPU chipsets and graphic processors, while major lower-performance products include integrated circuits used in consumer electronics products.

Tooling Design. We provide change kit and socket design services for mixed signal and RF integrated circuits.

Other Testing Services. In addition to wafer probing and final testing services described above, we also provide system-level
testing service for testing products on motherboards, lead/ball scanner service to screen out abnormal products, including bent lead or ball defective devices, so as to prevent them from being shipped to the end customers,
marking service to specify the unique customer logo and batch identification on products and tape and reel service to packaging devices into one complete reel for surface mount operation.

Customers

We currently
have more than 100 customers worldwide, and our customers include many of the largest semiconductor companies in the world. In 2012 and 2013, 57.0% and 60.0% of our net operating revenues were derived from sales to our top ten customers,
respectively. In 2013, our largest customer accounted for 8.3% of our net operating revenues. Our representative customers as of December 31, 2013 include Advanced Micro Devices Inc., Broadcom Corporation, Intel Corporation, MediaTek Inc.,
Marvell Semiconductor Inc., NVIDIA Corp., SanDisk Corporation and Xilinx, Inc. In general, we deal with the Asian subsidiaries of these leading semiconductor suppliers.

Industry-leading companies require early access to advanced packages because they manufacture products which have first-to-market
technologies. Our close relationships with industry-leading customers help us further develop their technologies and position us to benefit from the high unit volumes of these major semiconductor customers.

Sales from purchase orders received
from outside of Taiwan accounted for 78.7% and 78.1% of our net operating revenues in 2012 and 2013, respectively. We primarily target semiconductor companies that contract their wafer foundry services to major independent R.O.C. foundries. Our
customers, including AMD and NVIDIA Corp., are world-leading suppliers of graphic chipsets. Our customers mainly require chip scale packages and flip chip packages.

We believe we have benefited from our location in Taiwan where outsourced semiconductor manufacturing infrastructure is well established. Our
long-term relationships with two of the worlds largest independent wafer foundries are important to the continued growth of our services. A very large portion of the semiconductor devices we package and test is manufactured in Taiwans
leading wafer foundries. As these wafer foundries grow, we expect that their demand for our services will continue to grow. Moreover, we believe that we can leverage these relationships to jointly market seamless outsourced semiconductor
manufacturing services from design to drop shipment and remain at the forefront in semiconductor technology. We also believe that our close proximity and close relationships to wafer foundries enable our customers to more efficiently manage their
supply chains and find comprehensive solutions to their semiconductor needs.

##### Table of Contents

Due to the fast-changing technology and functionality of semiconductor chip design, customers
requiring semiconductor packaging and testing services generally do not place purchase orders far in advance. However, we engage customers in advance of the placement of purchase orders based on each customers expected packaging and testing
requirements. In addition, we purchase materials based on customer forecasts, and our customers are generally responsible for any dedicated unused materials in excess of the quantity they indicated they would need to meet their product commitments.
Although we have long-term sales relationships with a number of customers, our customers generally may cancel or reschedule orders without significant penalties. In the past, very few customers have cancelled firm orders for our packaging and
testing services. This is due in part to the fact that firm orders usually immediately precede shipment of wafers to be packaged by us. Our customers, however, routinely change their forecasts for future purchases from us, and we adjust our
production plans accordingly. We do not maintain reserves for customer cancellations and variations in customer orders. Accordingly, our backlog as of any particular date may not be indicative of future sales.

In addition, packaging and testing service customers generally require that our facilities undergo a stringent qualification
process during which the customer evaluates our operations and production processes. The qualification process can take many weeks. Due to this lengthy qualification process, we believe that semiconductor manufacturers are generally reluctant to
switch semiconductor packaging and testing companies once these companies have been qualified. For test qualification, after we are qualified by a customer and before the customer delivers wafers to us for testing in volume, a process known as
correlation is undertaken. During the correlation process, the customer provides us with test criteria, information regarding process flow and sample semiconductors to be tested and either provides us with the test program or requests
that we develop a new or conversion program. In some cases, the customer also provides us with a data log of results of any testing of the semiconductor that the customer may have conducted previously. The correlation process typically takes up to
two weeks but can take longer depending on the requirements of the customer.

Sales, Marketing and Customer Relationships

Our sales and marketing strategy is focused on providing high-quality semiconductor device packaging and testing services, consistent on-time
delivery and competitive pricing. We believe that this strategy is best implemented by servicing a select number of customers whom we consider to have a high level of anticipated growth. We cooperate with these customers to achieve their best needs.

We engage in semi-annual and quarterly reviews of all of our customers; we regularly collect data from different segments of the
semiconductor industry and, when possible, we work closely with our customers to design and develop packaging and testing solutions for their new products. These co-development or sponsorship projects can be critical when
customers seek large-scale, early market entry with a significant new product.

Our sales and marketing efforts are carried out by our
sales team in Taichung and Hsinchu among many of Taiwans leading domestic semiconductor companies.

In addition, our subsidiary
Siliconware U.S.A. has offices in San Jose, San Diego and Huntington Beach, California, Tempe, Arizona and Lewisville, Texas, which facilitate communications and maintain relationships with companies headquartered in North America. We also have
established our Japan office in Tokyo and Singapore office to give our customers support in closer proximity.

Quality Control

We employ quality control procedures at every critical manufacturing stage, with the aim of identifying and solving problems at the earliest
possible stage of the production process. Our quality control procedures include statistical process control, which involves sampling tests to control and monitor the production process. Such tests include optical scanning and reliability tests,
which include temperature and humidity tests, pressure and stress tests and test for resistance to solvents. If a problem is detected, failure analysis will be used to determine the cause. Visual inspection and optical scanning are performed on all
assembled semiconductor devices to test for lead coplanarity and integrity. Assembled chips are tested on a sample basis for open shorts in inter connections. To ensure that our quality control procedures are effectively applied, production line
employees are provided with periodic training. We have also implemented systems on our production floor which are designed to ensure the accurate use of required materials, parts, equipment and machinery for manufacturing each product.

Our comprehensive quality control and environmental protection programs have received numerous accredited International Standards Organization
certifications, including ISO 9002 in 1992, ISO 9001 in 1993, QS 9000 in 1999 and ISO 14001 in May 1999. We undergo periodic audits to maintain our ISO certifications. Although some semiconductor companies view the ISO certification as a basis for
initiating contact with a potential subcontractor, they generally perform separate production and quality audits of the subcontractors themselves. We also received TS16949 certification for our quality control in 2003, OHSAS 18001 certification for
safety and health management system in 2004, QC080000 certification for hazardous substance process management in 2008, TL9000 certification for telecommunications quality management system in July 2012, and ANSI/ESD S20.20 certification for ESD
control program to protect sensitive products from electrostatic discharge damage in June 2013.

##### Table of Contents

As a result of our ongoing focus on quality, we achieved average quarterly packaging yields of
99.8% in 2013. Packaging yield, which is the industry standard for measuring production yield, is equal to the number of IC packages that are shipped for packaging divided by the number of individual integrated circuits that are attached to
substrates, lead-frames, wafer level packages or system in packages.

As part of our overall focus on quality service, we also closely
monitor our delivery performance against scheduled delivery times.

Research and Development

We focus our research and development on developing advanced packaging technologies and also on improving the efficiency and capability of our
production processes in order to enhance our cost competitiveness in the industry.

Our packaging technologies development includes:



| |  |  | reduction of the size and thickness of semiconductor device packages;
| | - |  | ---------------------------------------------------------------------



| |  |  | increasing input/output density of semiconductor device packages;
| | - |  | -----------------------------------------------------------------



| |  |  | enhancing the electrical, thermal and reliability performance of semiconductor device packages;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | increasing packaging yield, shortening production cycle times; and
| | - |  | ------------------------------------------------------------------



| |  |  | investigating the use of new or replacement raw materials with lower cost.
| | - |  | --------------------------------------------------------------------------

Our key areas for
research and development are:



| |  |  | lead-frame and substrate packaging;
| | - |  | -----------------------------------



| |  |  | advanced flip chip packaging;
| | - |  | -----------------------------



| |  |  | copper pillar bumping and packaging;
| | - |  | ------------------------------------



| |  |  | integrated passive devices (IPD);
| | - |  | ---------------------------------



| |  |  | System in Package (SiP) design and process technologies;
| | - |  | --------------------------------------------------------



| |  |  | Through Silicon Via technology;
| | - |  | -------------------------------



| |  |  | Panel Fan Out technology; and
| | - |  | -----------------------------



| |  |  | 3D IC design and testing technologies.
| | - |  | --------------------------------------

We believe that technology development is one of the
key success factors in the semiconductor packaging and testing industry. We work with our customers, equipment manufacturers or materials suppliers to develop advanced processing capabilities. Moreover, we work with customers early in the process of
wafer design to ensure that their packaging needs are met and that our packaging services provide our customers with the flexibility they require. Our research and development personnel are divided among our technology and package development
department, design and characterization department and manufacturing technology development department. In addition, our quality assurance and manufacturing personnel also participate in research and development activities. In 2012 and 2013, our
research and development expenses amounted to NT$2,559 million and NT$3,407 million (US$114.2 million), respectively.

We maintain
laboratory facilities to analyze the characteristics of semiconductor device packages by computer simulation and verify their performances by measurement devices. The use of computer-aided engineering tools substantially reduces the time required to
validate the proper function of packages, as compared to physical testing methods.

Raw Materials and Equipment

Raw Materials

Our
packaging operations require adequate supplies of materials and equipment on a timely basis. The principal raw materials used in packaging are substrates, lead-frames, gold wire and molding compound. We generally have not entered into long-term
supply agreements and purchase our raw materials on a purchase order basis at prevailing market prices. The price of gold wire has been volatile and has fluctuated with the spot price of gold in recent years. In 2013, the spot price of gold
fluctuated from a low of approximately US$1,195.25 per ounce to a high of approximately US$1,693.75 per ounce. We have continued to implement measures to reduce our dependency on certain raw materials, such as gold wire. For example, we are
continuing to develop improvements to our manufacturing process that will shorten the length and reduce the diameters of the gold wire used. In addition, we are continuing to develop copper wire bonding processes. Our major suppliers of raw
materials, which include Nanya Printed Circuit Board Corp., Unimicron Technology Corp. and Kinsus Interconnect Technology Corp., are leading companies in the types of materials they supply. We work closely with them and provide them with rolling
forecasts. For 2012 and 2013, our raw material costs were 49.7% and 45.3%, respectively, of operating costs.

We do not maintain large
inventories of raw materials. We purchase materials based on customer forecasts, and our customers are generally responsible for any unused materials in excess of the quantity they indicated they would need to meet their product commitments. Based
upon regular estimates of orders from customers, we usually maintain limited inventories of raw materials. Our principal suppliers usually dedicate portions of their inventories as reserves to meet our production requirements. Nevertheless, on
occasion when customer orders have exceeded the supply of raw materials, we have typically been able to obtain extensions from our customers to allow sufficient supply to become available. Such arrangements help us remain cost competitive.

Equipment

In
addition to raw materials, the availability of packaging and testing equipment is critical to our services. We generally seek to maintain equipment from different suppliers with broad functionality and flexibility for different packaging types to
enhance capacity utilization. We purchase packaging equipment from major international manufacturers, including Kulicke & Soffa Industries Inc., DISCO Corporation and Applied Materials South East Asia Pte, Ltd.

Testing equipment is one of the critical components of the wafer probing and device testing process. We generally seek to maintain testers
from different suppliers with similar functionality and the ability to test a variety of different semiconductors. In general, certain semiconductors can only be tested on a limited number of specially configured testers. Our major suppliers of
testing equipment include Advantest Taiwan Inc., Teradyne Inc. and Kanematsu Corporation.

As of December 31, 2013, we operated 6,050
wire bonders and 331 testers in Taiwan. In addition, our subsidiary, Siliconware Suzhou has 1,709 wire bonders and 51 testers in the P.R.C. We must order equipment in advance of customer demand to expand our capacity, based on our expectation of
future demand for our packaging and testing services.

Competition

We face substantial competition from established packaging and testing service providers, including companies with greater manufacturing,
financial and other resources. These companies include Advanced Semiconductor Engineering, Inc. (Taiwan), Amkor Technology Inc. (USA) and STATS ChipPAC Ltd. (Singapore). These companies have also established relationships with many large
semiconductor companies that are our current or potential customers. To a lesser extent, we also compete with the internal semiconductor packaging and testing capabilities of many of our customers.

The principal elements of competition in the independent semiconductor packaging and testing market include:



| |  |  | the breadth of package and test offerings;
| | - |  | ------------------------------------------



| |  |  | technical competence;
| | - |  | ---------------------



| |  |  | manufacturing yields;
| | - |  | ---------------------



| |  |  | manufacturing cycle times;
| | - |  | --------------------------



| |  |  | customer service; and
| | - |  | ---------------------



| |  |  | price.

##### Table of Contents

Integrated Device Manufacturers, or IDMs, that use our services continually evaluate our
performance against their own in-house testing and assembly capabilities. These IDMs may have access to more advanced technologies and greater financial and other resources than we do. We believe, however, that we can offer greater efficiency and
lower costs while maintaining an equivalent or higher level of quality for three reasons:



| |  |  | we offer a broader and more complex range of services as compared to the IDMs, which tend to focus their resources on improving their front-end operations;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we generally have lower unit costs because of our higher utilization rates; and
| | - |  | -------------------------------------------------------------------------------



| |  |  | we offer a wider range of services in terms of complexity and technology.
| | - |  | -------------------------------------------------------------------------

Strategic
Investments and Dispositions

We enter into equity joint ventures with and make strategic investments and dispositions in companies
located in Taiwan, Singapore and the United States engaged in related semiconductor packaging and testing businesses. We believe that our participation in these companies allows us to enhance and complement our manufacturing services offerings,
secure access to raw materials and keep us up to date with technological changes in the semiconductor industry. These participations include:



| |  |  | Unimicron Technology Corporation, or Unimicron. As of December 31, 2013, we held a 4.97% equity interest in Unimicron, a supplier of semiconductor raw materials, including substrates.

| |  |  | In order to enhance our assembly-related techniques, we purchased preferred stock of Vertical Circuits, Inc, or VCI. Our ownership in VCI remained approximately 30.68% as of December 31, 2013. VCIs board of
directors resolved to file for bankruptcy protection in July 2012. Accordingly, we recognized an impairment loss of NT$94.4 million in 2012.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | AcSiP Technology Corp., or AcSiP. As of December 31, 2013, we owned approximately 11.99% of AcSiP, a provider of single and integrated wireless system-in-package solutions.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In order to develop new generation substrates and increase substrate supply sources, we acquired 22,865,385 shares of Microcircuit Technology (S) Pte. Ltd., or MCT, a substrate supplier located in Singapore, for
US$20.5 million in July 2012. In December 2013, we invested another US$ 1.06 million and our total holdings increased to 24,039,552 shares. Our percentage of ownership in MCT remains at approximately 42.27%.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Intellectual Property

As
of December 31, 2013, we held 383 Taiwan patents, 358 U.S. patents and 95 P.R.C. patents related to various semiconductor packaging technologies, including patents for improvements of thermal and electrical performance used in the semiconductor
packaging process. As of December 31, 2013, we also had a total of 166 pending patent applications in the United States, 325 in Taiwan and 223 in the P.R.C. In addition, SPIL is registered as a trademark and as a servicemark in
Taiwan.

We have licensed from Freescale, formerly part of Motorola prior to April 2004, the technology for ball grid array packages. This
license will expire in December 2015.

We have also entered into other technology alliances by licensing package technologies, including:



| |  |  | Wafer Bumping and Redistribution technology, which enables us to form and/or redistribute bumps on the chip to make a silicon die, is able to be directly attached to the substrate using the aforementioned bumps rather
than wire bonding. This license does not have an expiration date.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Wafer Level CSP technology, which enables us to produce a chip scale package at the stage of wafer level. This license does not have an expiration date.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------

Our ongoing royalty expenses to license intellectual property for the years ended December 31, 2012 and 2013 were immaterial compared to
our revenues.

##### Table of Contents

We expect to continue to file patent applications where appropriate to protect our proprietary
technologies. We may need to enforce our patents or other intellectual property rights or to defend ourselves against claimed infringement of the rights of others through litigation, which could result in substantial cost and diversion of our
resources.

The semiconductor industry is characterized by frequent claims regarding patent and other intellectual property rights. If a
third party were to bring a valid legal claim against us, we could be required to:



| |  |  | discontinue the use of disputed process technologies;
| | - |  | -----------------------------------------------------



| |  |  | pay substantial damages;
| | - |  | ------------------------



| |  |  | develop non-infringing technologies; or
| | - |  | ---------------------------------------



| |  |  | acquire licenses to the technologies that we had allegedly infringed.
| | - |  | ---------------------------------------------------------------------

Environmental
Matters

The principal pollutants produced during semiconductor packaging are wastewater, industrial waste (liquid waste and solid
waste) and flue gas from the processes including solder plating, wafer grinding and die sawing. During these processes, wastewater is produced when water is used for cooling and rinsing wafers while they are being sawed and ground or for rinsing
semiconductor chips when lead-frames are being plated.

In addition, solid waste materials are produced during the packaging process
including scraps such as metal lead-frame, printed-circuit-board-like substrate and excess molding resin.

As for the newly developed
bumping process, wastewater is produced when water is used for rinsing wafers in the processes of etching and solder deposition. Flue gas comes from the emissions of solvents that are used for coating, developing during the bumping process. Liquid
waste is mainly derived from photo resistant strip and bumping plating.

To mitigate environmental claims, we maintain pollution control
facilities in good conditions at all of our factories. We have installed various types of pollution control equipment dedicated to different properties of pollutants for the best treatment of flue gas and wastewater in our factories. As part of our
pollution control programs, we also subcontract certain industrial waste disposal and recycling work to suppliers who are qualified by the Environmental Protection Administration. Furthermore, we also actively monitor any changes in the
international environmental requirements in the electronic and semiconductor industries in order to respond quickly to such changes. We believe that we are in compliance with the applicable environmental requirements of semiconductor industries and
regulations in Taiwan in all respects.

We have consistently followed the environmental practice of reducing pollution from our
manufacturing processes and continual performance improvement. Our environmental management meets and complies with R.O.C. and all international environmental requirements. We have implemented an international environmental management system since
1998 and received the ISO-14001 certification in 1999. By continually improving our environmental performance over the years, we have changed the pollution control method from production operations to source management, which focuses on prohibiting
or restricting the use of environmentally hazardous substances in materials. We made this change to meet the growing consumer trend for green products. In March 2003, we passed Sony Corporations Green Partner qualification with a perfect
score. In addition, in 2008 our hazardous substance process management system has received QC080000 certification, which is a new industrial management standard for the production of environmentally friendly products.

We also have taken various energy saving and carbon reduction measures to reduce our greenhouse gas emissions. Since 2005, we have conducted
annual greenhouse gas emission inventories. We also have been disclosing through the Carbon Disclosure Project since 2007. In 2010, we completed our greenhouse gas inventory and verification of all factories and dormitories in Taiwan according to
the ISO 14064-1 standard. Moreover, we completed product carbon footprint inventory and verification for a particular product (TFBGA) in 2011, in accordance with the PAS 2050 standard. In order to control energy usage, we have conducted the ISO
50001 energy management system and obtained the certification in 2013.

Insurance

We have insurance policies covering physical damage to buildings, equipment and inventories caused by natural disasters and other perils, and
the loss of gross profit caused by the insured perils. We also insure ordinary transit and transportation risks for delivery of our inventories and products resulting from our services.

There is an emergency response team in place capable of responding to situations on a real time
basis in order to prevent or minimize the possibility of loss to personnel or our facilities, equipment, machinery and inventories.

We
have directors and officers liability insurance in place to cover losses that a director or officer becomes legally obligated to pay on account of a claim made against that director or officer from an alleged or actual wrongful act committed in an
executive capacity.

Employees

See Item 6. Directors, Senior Management and Employees  D. Employees for certain information relating to our employees.

Capital Expenditures and Divestitures

Our capital expenditures amounted to NT$15,142 million and NT$14,979 million (US$502.1 million) in 2012 and 2013, respectively. Our initial
budget for capital expenditures for 2014 is approximately NT$14,700 million (US$492.8 million), which is mostly funded from our retained earnings and borrowings. We expect our capital expenditures in 2014 will primarily consist of expanding our
advanced packaging and testing capacity. We may adjust the amount of our capital expenditures upward or downward based on the progress of our capital projects, market conditions and our anticipation of future business outlook. See Item 5.
Operating and Financial Review and ProspectsB. Liquidity and Capital Resources.

Litigation

On March 1, 2006, we were informed of the California Litigation brought by Tessera, in the United States District Court for the Northern
District of California against us, our subsidiary Siliconware U.S.A., Inc. and five other semiconductor companies and their subsidiaries. Tessera alleged that some of our packaging services infringe patents owned by Tessera and that we breached a
license agreement with Tessera. In April 2013, we settled the California Litigation by agreeing to pay US$30 million. See Item 3. Key Information  D. Risk Factors  Risks Relating to Our Technologies  Disputes over
intellectual property rights could be costly and could deprive us of technologies to stay competitive.

|Item 5. | Operating and Financial Review and Prospects
|------- | --------------------------------------------

Unless stated otherwise, the discussion
and analysis of our financial condition and results of operations in this section apply to our financial information as prepared according to IFRS. You should read the following discussion of our financial condition and results of operations
together with the financial statements and the notes to these statements included in this annual report.

A. Operating Results

Overview

We
are one of the worlds leading independent providers of semiconductor packaging and testing services. We offer a full range of packaging and testing solutions, including advanced substrate packages such as flip-chip ball grid packages, together
with lead-frame packages, and testing services for logic and mixed signal devices. We also offer our customers complete turnkey solutions, including packaging, testing and drop shipment service.

We recorded operating income of NT$6,388 million and NT$7,935 million (US$266.0 million) in 2012 and 2013, respectively. This increase was
mainly attributable to the increase in revenue and continuing improvements in our cost structure. See Results of Operations.

Intense competition in the semiconductor industry worldwide resulted in decreases in the average selling prices of our manufacturing services.
We expect that average selling prices for most of our semiconductor packages to continue to decline in the future. A decline in average selling prices of our semiconductor packages, coupled with high depreciation cost resulting from our purchase of
additional equipment during the previous periods, if not offset by reductions in the other cost of producing those packages, would decrease our gross margins.

To counter the effects of decreasing average selling prices, we will continue to attempt to:



| |  |  | negotiate better pricing terms with our suppliers, including quantity discounts;
| | - |  | --------------------------------------------------------------------------------



| |  |  | find less expensive alternative sources of raw materials;
| | - |  | ---------------------------------------------------------



| |  |  | maximize production efficiency of our equipment; and
| | - |  | ----------------------------------------------------



| |  |  | engage in utility conservation programs.
| | - |  | ----------------------------------------

We do not maintain reserves for cancellations or
variations in customer orders.

General Factors Affecting Our Results of Operations

General factors affecting our results of operations are the global economy and conditions in the semiconductor markets. In addition, our
results of operations were also affected by gold prices, the fluctuation of the New Taiwan Dollar and rising wage levels.

Consolidation

In
accordance with IFRS, we consolidated four subsidiaries: SPIL (B.V.I.) Holding Limited, Siliconware U.S.A. Inc., SPIL (Cayman) Holding Limited and Siliconware Technology (Suzhou) Limited, each in which we own a 100% equity interest.

Expansion and Utilization Rate

As we focus on aligning our capacity to meet changing customer demand, the number of our wire bonders decreased from 7,805 as of
December 31, 2012 to 7,759 as of December 31, 2013.

Our operating results are affected by relatively high fixed costs. As a
result, capacity utilization rates can significantly affect margins as the unit cost of packaging and testing services generally decreases as fixed charges, including depreciation expenses on our equipment, are allocated over a larger number of
units. Our utilization rates have varied from period to period as we have expanded our production capacity. We have been successful in minimizing the industry-wide fluctuation in capacity utilization rates by deploying flexible equipment for
different packages and also by utilizing our test equipment for both IC testing and wafers probing purposes. Our ability to maintain or enhance our margins will continue to depend in part on our ability to effectively manage capacity utilization
rates. The capacity utilization rates of our facilities were approximately 93% and 88% in 2012 and 2013, respectively.

Recent
Accounting Changes

In accordance with the requirements of the FSC beginning on January 1, 2013, we have adopted Taiwan IFRS, for
reporting our annual and interim consolidated financial statements in the R.O.C. There are certain material differences between Taiwan IFRS and IFRS. We will furnish a report on Form 6-K in April 2014 explaining the impacts of differences between
Taiwan IFRS and IFRS with respect to our consolidated financial results in 2013.

The selected consolidated financial data set forth below
as of and for the years ended December 31, 2012 and 2013 have been derived from our audited consolidated financial statements as of and for the years ended December 31, 2012 and 2013, which have been prepared in accordance with IFRS as
issued by the IASB.

Historically, we prepared our financial statements in accordance with R.O.C. GAAP. As of January 1, 2013, we
have adopted IFRS as issued by the IASB, and prepared our first consolidated financial statements in accordance with IFRS 1 First-time of adoption of IFRS. Starting January 1, 2013, we have prepared our consolidated financial information in
accordance with IFRS. A description of the principal differences between our previous accounting standards and IFRS and the impacts of transition to IFRS is provided in note 37 to our consolidated financial statements included in this annual report.

Applications of Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements included
elsewhere in this annual report, which have been prepared in accordance with IFRS. The preparation of our audited consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets and
liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, accounts receivable and allowance for doubtful accounts,
inventory reserves, deferred tax asset valuation allowance, employee bonuses, and impairment of long-lived assets and equity investments. We base our estimates on historical experience and on various other assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates using
different assumptions or conditions. Further discussion of these critical accounting estimates and policies is included in the notes to our consolidated financial statements.

The accounting policies set out below have been applied consistently by us and our subsidiaries to all periods presented in these consolidated
annual financial statements and in preparing the opening IFRS statement of financial position as of January 1, 2012 for the purposes of the transition from R.O.C. GAAP to IFRS, unless otherwise indicated.

We believe the following critical accounting policies involve significant judgments and estimates used in the preparation of our audited
consolidated financial statements.

Revenue Recognition

We principally provide assembly and testing services of integrated circuits, which may be assembly only, testing only or turnkey solutions. We
recognize revenues when:



| |  |  | the amount of revenue can be measured reliably;
| | - |  | -----------------------------------------------



| |  |  | it is probable that the economic benefits associated with the transaction will flow to the entity;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | the stage of completion of the transaction at the end of the reporting period can be measured reliably; and
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | the costs incurred for the transaction and the cost to complete the transaction can be measured reliably.
| | - |  | ---------------------------------------------------------------------------------------------------------

The revenue amount to be recognized is based on the agreed price by both parties of the transaction and the stage of completion. Sales
allowance is estimated based on historical experiences and recorded as a deduction to the revenue.

Accounts Receivable and
Allowances for Doubtful Accounts

Accounts receivable is recognized initially at fair value and subsequently measured at amortized
cost using the effective interest method, less provision for impairment. We record accounts receivable expected to be collected over one year at present value by using predetermined interest rate whereas those expected to be collected within one
year are not reported at present value due to the fact that the difference between the maturity value and the fair value discounted by implicit interest rate is immaterial and the frequency of transactions is high. The allowance for doubtful
accounts is provided based on the estimated allowance to be incurred and is recorded as deduction of accounts receivable.

Inventory
Reserves

In general, raw materials are purchased based on the customers forecasted demand. If our customers change their
forecasted requirements and we are unable to cancel our excess raw material orders, we would experience a buildup in our raw material inventory. We could either seek to recover the cost of the materials from our customers or utilize the inventory in
production. However, we may not be successful in recovering the cost from our customers or in using such excess inventory in production, which we would consider as part of our reserve estimate. Our reserve for excess and obsolete inventory is based
on forecasted demand we receive from our customers. When a determination is made that the inventory would not be utilized in production, it is written off and disposed of. Actual demand may differ from our forecast and may result in additional
reserve.

Inventories are recorded at cost when acquired under a perpetual inventory system. Cost is determined using the
weightedaverage method. The allowance for loss on obsolescence and decline in market value is recorded based on inventory aging and obsolescence, when necessary. Inventories are stated at the lower of cost or net realizable value by item,
except where it may be appropriate to group similar or related items. Net realizable value is the estimated selling price in the ordinary course of business less all estimated costs of completion and necessary selling expenses.

##### Table of Contents

Impairment of Long-Lived Assets

We review long-lived assets for the purpose of determining the amount of impairment quarterly under IFRS. We perform impairment test whenever
an event occurs or evidence indicates that the carrying amount of an asset exceeds its recoverable amount. Recoverable amount is measured as the higher of the fair value less cost to sale or value in use. The fair value less cost to sale is the
amount obtainable from the sale of an asset in an arms-length transaction after deducting any direct incremental disposal costs. The value in use is the present value of estimated future cash flows expected to arise in its remained useful
life.

An impairment loss recognized in prior years is reversed if such impairment loss caused by a specific external event of an
exceptional nature is not expected to recur. However, the restored amount is limited to the amount of impairment loss previously recognized. Impairment loss for goodwill cannot be reversed.

In 2012 and 2013, we recognized an impairment charge of NT$192 million and NT$112 million (US$3.8 million), respectively, for packaging and
testing assets to be disposed of to reduce the carrying value of the assets to their estimated fair value less cost of sale. The fair value of the assets to be disposed of was determined by the estimated net realizable value of the assets. We
determined the estimated net realizable value of these assets based on the condition and anticipated future cash flows of these assets. The impairment charge was mainly related to our decision to dispose certain machinery and equipment due to
technology phase out and replacement in 2012 and 2013.

Provision for Income Taxes and Deferred Tax Assets and Liabilities

As of December 31, 2013, we had approximately NT$138 million (US$4.6 million) of net deferred income tax assets related
principally to investment tax credits that expire at various dates through 2015, and deferred tax liabilities for an additional 10% undistributed earnings tax. Deferred income tax is recognized, using the liability method, on temporary differences
arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill, and deferred
income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred
income tax is determined using tax rates that have been enacted or substantively enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.
Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized.

Description of Revenue and Cost Items

Net Operating Revenues

We generate our net operating revenues primarily from semiconductor packaging and testing operations. Net operating revenues from our
semiconductor packaging activities consist of our service fees and the cost of raw materials we purchase to provide semiconductor packaging services. We price our packaging services on a per unit basis taking into account the complexity of the
services to be provided, the prevailing market conditions, the order size, the strength and history of our relationship with the customer and our capacity utilization. We charge our testing services based on the specific test and the time, usually
measured in seconds, to run a test, taking into account the complexity of the semiconductor device and the customers test program. Our customers are generally invoiced at the time when services are rendered, with varying terms of credit
between 30 and 90 days from the time of billing.

Operating Costs

Our operating costs consist principally of:



| |  |  | cost of raw materials purchased for semiconductor packaging services;
| | - |  | ---------------------------------------------------------------------



| |  |  | direct labor costs; and
| | - |  | -----------------------



| |  |  | overhead, including depreciation and maintenance of production equipment, indirect labor costs, indirect material costs and utilities.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

Operating Expenses

Our operating expenses consist of the following:



| |  |  | Selling, General and Administrative Expenses. Selling, general and administrative expenses consist primarily of salaries and related personnel expenses, other marketing expenses, fees for professional services, and the
cost of computers to support our operations.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Research and Development Expenses. Research and development expenses consist primarily of salaries, bonuses and related costs for technology development, technology license fees allocated to research and development,
and depreciation on and maintenance of equipment and various materials used in our research and development processes. We expect our research and development expenses to grow as we hire additional staff and purchase additional equipment for research
and development purposes.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Taxation

The corporate income tax rate in Taiwan, which currently applies to us, is 17%. Based on our status as a company engaged in the semiconductor
packaging business in Taiwan, we have been granted exemptions from income taxes in Taiwan because we used the proceeds raised through the offering of American depository receipts and capitalization of earning for the purpose of purchasing equipment.
As permitted by Taiwan tax regulation, we can use these exemptions for five years from the date when we begin to generate income from the use of this equipment. However, these tax exemptions expired in December 2012 and May 2013, respectively. Tax
savings amounted to approximately NT$93 million in 2012 and NT$25 million (US$ 0.8 million) in 2013.

Furthermore, the Industrial
Development Bureau of the Ministry of Economic Affairs granted permission for a five-year income tax exemption of our 2007 registered capitalization plan in 2008. We acquired the work completion certificate from the Taichung City Government Economic
Development Bureau in 2013. As such, this five-year tax exemption may start from a year we elect between 2013 and 2016. We have not yet elected a start year for this tax exemption, but intend to do so in 2014.

We also benefit from other tax incentives generally available to technology companies, including tax credits ranging from 30% to 50% for
research and development and employee training expenses and tax credits ranging from 7% to 11% for investment in automation equipment and technology and certain qualifying investments. However, according to the Industrial Innovation Actissued on May 12, 2010, the deductible rate of investment tax credit for qualifying research and development expenditures was reduced from 30% to 15% starting January 1, 2010. Historically, these tax incentives have resulted in
decreases of income tax payable by approximately NT$ 238 million and NT$ 336 million (US$ 11.3 million) in 2012 and 2013, respectively. In 2012 and 2013, our effective income tax rates were 11.34% and 12.30%, respectively.

The Year ended December 31, 2013 compared to the Year Ended December 31, 2012

Net operating revenues. Net operating revenues increased by 7.3% from NT$64,655 million in 2012 to NT$69,356 million (US$ 2,325.0
million) in 2013. The increase in net operating revenues was primarily due to the increase in semiconductor demand.

Substrate base
package sales increased by 13.1% from NT$35,042 million in 2012 to NT$39,650 million (US$ 1,329.2 million) in 2013. The increase in substrate base package sales was due to the increase in advanced packaging sales. In 2013, substrate base package
accounted for 57.2% of our net operating revenues, up from 54.2% in 2012.

Lead-frame base package sales decreased by 6.6% from NT$16,368
million in 2012 to NT$15,290 million (US$512.6 million) in 2013. The decrease in lead-frame base package sales was attributable to the drop in average selling price and customers converting from lead-frame to substrate products. In 2013, lead-frame
base package accounted for 22.0% of our net operating revenues, down from 25.3% in 2012.

Gross profit and gross margin. Our gross
profit increased by 22.9% from NT$ 11,739 million in 2012 to NT$ 14,431 million (US$ 483.8 million) in 2013 mainly due to the increase of operating revenues. Our gross margin (gross profit as a percentage of net operating revenues)
increased from 18.2% in 2012 to 20.8% in 2013, mainly attributed to favorable product mix and effective internal cost management. Our operating costs increased by 3.8% from NT$52,916 million in 2012 to NT$54,926 million (US$1,841.3 million) in 2013,
in line with our increase in operating revenues.

Operating expenses. Operating expenses increased by 21.4% from NT$5,351 million
in 2012 to NT$6,495 million (US$ 217.7 million) in 2013. Operating expenses as a percentage of net operating revenues was 8.3% and 9.4% in 2012 and 2013, respectively.

Selling expenses.Selling expenses increased by NT$31 million between these two years mainly due to the increase in commission expense.

##### Table of Contents

General and administrative expenses.General and administrative expenses increased by
NT$265 million mainly due to the increase in salary expense.

Research and development expenses. Research and development expenses
increased by NT$848 million mainly due to the increase in salary expense and development expenses for new products.

Operating income
and operating margin. We recorded operating income of NT$ 6,388 million and an operating margin of 9.9% (operating income as a percentage of net operating revenues) in 2012 and generated operating income of NT$7,935 million (US$266.0
million) and operating margin of 11.4% in 2013. The increase in operating margin was primarily due to the increase in our sales revenues.

Net non-operating income.Our net non-operating income decreased from gains of NT$404 million in 2012 to losses of NT$486 million
(US$16.3 million) in 2013. The decrease in net non-operating income was primarily due to the settlement loss with Tessera.

Income tax
expense. We recognized income tax expense of NT$1,230 million in 2012 compared to NT$1,607 million (US$53.9 million) in 2013 primarily due to an increase in taxable income.

Net income. As a result of the factors discussed above, our net income increased from NT$5,562 million in 2012 to NT$5,842 million
(US$195.8 million) in 2013.

B. Liquidity and Capital Resources

We need cash primarily for capacity expansion, equipment purchases and working capital. We believe that our working capital is sufficient for
our requirements for the next year. Although we have historically been able to satisfy our working capital needs from cash flow from operations, our ability to expand our capacity has been largely dependent upon, and will continue to depend upon,
our ability to finance these activities through the issuance of equity securities, long-term borrowings and the issuance of convertible and other debt securities. Our ability to meet our working capital needs from cash flow from operations will be
affected by the demand for our manufacturing services, which in turn may be affected by several factors, many of which are outside of our control, such as economic downturns and declines in the average selling prices of our manufacturing services
caused by oversupply in the market. To the extent that we do not generate sufficient cash flow from our operations to meet our cash requirements, we may rely on external borrowings and securities offerings. We have not historically relied, and we do
not plan to rely in the foreseeable future, on off-balance sheet financing arrangements to finance our operations or expansion.

Liquidity

As of
December 31, 2013, our primary source of liquidity was NT$16,975 million (US$ 569.1 million) of cash and cash equivalents. As of December 31, 2013, we had total availability under existing short-term lines of credit of NT$8,446 million
(US$282.9 million) from seven domestic and foreign financial institutions, of which NT$2,667 million (US$89.3 million) were used as letters of credit, guarantees and short-term borrowings. All of our short-term facilities are revolving facilities
with a term of one year, which may be extended for terms of one year each with lenders consent. We entered into a multi-purpose credit facility led by Mega International Commercial Bank in October 2010 in the amounts of NT$5,000 million and
US$150 million for capacity expansion and working capital purposes. This facility is a long-term floating interest rate credit facility expiring on October 29, 2015. On November 5, 2010, we drew down NT$4,377 million from this credit
facility. On September 30, 2011, we drew down NT$5,000 million from this credit facility. On April 29, 2013, we repaid NT$833 million and US$25 million, and on October 29, 2013, we repaid the same amounts again. We entered into a
credit facility led by Mega International Commercial Bank in August 2012 in the amounts of NT$3,257 million and US$250 million for capacity expansion. This facility is a long-term floating interest rate credit facility expiring on August 10,
2017. On August 31, 2012, we drew down NT$1,500 million and US$150 million from this credit facility. On June 30 and September 30, 2013, we drew down NT$1,757 million and USD$100 million from this credit facility respectively. We
entered into a credit facility led by China Development Industrial Bank in November 2013 in the amount of NT$1.5 billion for working capital purposes. This facility is a long-term floating interest rate credit facility expiring on December 31,
2016. On December 31, 2013, we drew down NT$1.5 billion from this credit facility. As of December 31, 2013, we had short-term and long-term borrowings of NT$2,534 million (US$84.9 million) and NT$18,540 million (US$621.5 million),
exclusive of loan arrangement fees of NT$30 million, respectively, outstanding under these facilities.

Net Cash Provided by Operating Activities

In 2013, net cash provided by operations was NT$17,748 million (US$595.0 million) compared to NT$13,366 million in 2012. The increase in net
cash provided by operating activities was primarily the result of an increase of net income and depreciation in 2013.

Net Cash Used in
Investing Activities

In 2013, cash used in investing activities was NT$15,588 million (US$522.6 million) compared to NT$15,872 million
in 2012. The decrease in net cash used in investing activities was primarily the result of a decrease in cash invested in the investments accounted for using the equity method.

Net Cash Provided by (Used in) Financing Activities

Net cash used in financing activities was NT$1,150 million (US$38.6 million) in 2013. In 2013, net cash used in financing activities reflected
primarily the payment of stockholders dividends of NT$5,141 (US$172.3 million).

Net cash provided by financing activities was
NT$2,520 million in 2012. In 2012, net cash provided by financing activities reflected primarily proceeds from borrowings of NT$6,980 million and the payment of stockholders dividends of NT$4,371 million.

Capital Resources

We
have made, and expected to continue to make, substantial capital expenditures in connection with the expansion of our equipment purchases and building improvements in Taichung, Hsinchu, Changhua and Suzhou. See Item 4. Information on the
CompanyB. Business OverviewCapital Expenditures and Divestitures. Our initial budget for capital expenditures for 2014 is approximately NT$14,700 million (US$492.8 million), which is mostly funded from our retained earnings and
borrowings. We expect that our capital expenditures in 2014 will primarily consist of expanding our advanced packaging and testing capacity. We may adjust the amount of our capital expenditures upward or downward based on the progress of our capital
projects, market conditions and our anticipation of future business outlook. As a result, we may need to invest in new capacity to improve our economies of scale and reduce our production cost, which would require us to raise additional capital. We
cannot assure you that we will be able to raise additional capital should it become necessary on terms acceptable to us or at all. We entered into a multi-purpose credit facility led by Mega International Commercial Bank in October 2010 in the
amounts of NT$ 5,000 million and US$ 150 million for capacity expansion and working capital purposes. This facility is a long-term credit facility expiring on October 29, 2015. On November 5, 2010, we drew down NT$4,377 million
from this credit facility. On September 30, 2011, we drew down NT$5,000 million from this credit facility. On April 29, 2013, we repaid NT$833 million and US$25 million, and on October 29, 2013, we repaid the same amounts again. We
entered into a credit facility led by Mega International Commercial Bank in August 2012 in the amounts of NT$3,257 million and US$250 million for capacity expansion. This facility is a long-term credit facility expiring on August 10, 2017. On
August 31, 2012, we drew down NT$1,500 million and US$150 million from this credit facility. On June 30 and September 30, 2013, we drew down NT$1,757 million and USD$100 million from this credit facility respectively. We entered into
a credit facility led by China Development Industrial Bank in November 2013 in the amount of NT$1.5 billion for working capital purposes. This facility is a long-term floating interest rate credit facility expiring on December 31, 2016. On
December 31, 2013, we drew down NT$1.5 billion from this credit facility.

Transactions with Related Parties

We have not extended any loans or credit to any of our directors, supervisors or executive officers, and we have not provided guarantees for
borrowings by any of these persons. We have not entered into any fee-paying contract with any of these persons to provide services not within the capacity of director, supervisor or executive officer of our company.

We have, from time to time, purchased raw materials and sold our manufacturing services to our
affiliated companies. We believe that these transactions with related parties have been conducted either on arms-length terms or on terms more favorable to us than arms-length terms. See Item 7. Major Shareholders and Related Party
TransactionsB. Related Party Transactions.

Inflation

The inflation rate in Taiwan was 1.42% in 2011, 1.93% in 2012 and 0.79% in 2013. We do not believe that inflation in Taiwan has had a material
impact on our results of operations.

Recent Accounting Pronouncements

In May 2013, the IASB issued IFRIC Interpretation 21: Levies, an Interpretation on the accounting for levies imposed by governments. It
addresses the accounting for levies imposed by governments in accordance with legislation, other than income tax. A liability to pay a levy shall be recognized in accordance with IAS 37 Provisions, contingent liabilities and contingent
assets. The interpretation is effective for reporting periods starting from January 1, 2014.

We are assessing the influence of
the new standards, interpretations and amendments above, and have not yet been able to reliably estimate the impacts on the consolidated financial statements.

reasonably likely to have a material effect on our net sales or operating revenues, income from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information not necessarily to be indicative
of future operating results or financial condition.

E. Off-Balance Sheet Arrangements

As of December 31, 2013, we do not have any off-balance sheet arrangements.

F. Tabular Disclosure of Contractual Obligations

Compensation Committee

We currently follow the practice under the R.O.C. Securities and Exchange Act, as amended on November 24, 2010, which requires all
publicly listed companies in the R.O.C., including our company, to establish a remuneration committee for directors, supervisors and managers compensation, which includes salary, stock options and other rewards. On March 18, 2011, the FSC
promulgated Regulations Governing the Appointment and Exercise of Powers by the Remuneration Committee of a Company Whose Stock is Listed on the Stock Exchange or Traded Over the Counter, according to which publicly listed companies of
our size were required to establish a remuneration committee composed of no less than three members appointed by the board of directors by September 30, 2011. Such committee members must meet certain professional qualification requirements and
must not have served as an employee or non-independent director of the company in the two years prior to their appointment. Pursuant to such regulations, on August 25, 2011, we established a remuneration committee comprised of William W. Sheng,
Professor of the National Taichung Institute of Technology, Tsai-Ding Lin, Professor of Tunghai University, and Jing-Shan Aur, one of our independent directors.

D. Employees

As of December 31, 2012 and 2013, we, together with our subsidiaries, had 21,566 and 22,799 full-time employees, respectively. Of these
employees, as of December 31, 2013, 19,733 were located in Taiwan, 3,000 were located in Mainland China, and 66 were located in the United States. Employee salaries are reviewed once or twice a year. Salaries are adjusted based on industry
standards, inflation and individual performance. As an incentive, additional bonuses in cash may be paid at the discretion of the management based on the performance of individuals. In addition, R.O.C. law requires that employees be given preemptive
rights to subscribe to between 10% and 15% of any of our rights issues or share offerings.

According to R.O.C. Labor Pension Act
effective since July 1, 2005, we contribute 6% of our employees monthly salaries to the Bureau of Labor Insurance for those employees who choose to participate in the portable pension schemes. For our employees who choose to
apply for the pension mechanism under the Labor Standards Act, we contribute 2% of their monthly salaries to the Workers Retirement Reserve Funds maintained by the Bank of Taiwan.

Our employees participate in our profit distribution under our articles of incorporation. Employees are entitled to receive bonus shares based
on a percentage of our allocable surplus income. We accrued employees cash bonuses of NT$469 million (US$15.7 million) in 2013.

We
do not have any collective bargaining arrangement with our employees, and we have never experienced a work stoppage caused by our employees. We believe we have good relations with our employees. We do not have any labor unions.

B. Related Party Transactions

Related Party Transactions Policies

We from time to time have engaged in a variety of transactions with our affiliates. We conduct transactions with our affiliates on terms
substantially as favorable to us as would be obtainable at the time in a comparable arms-length transaction with non-affiliates.

Vertical Circuits, Inc.

In recent years, we have been licensing packaging technologies from VCI. In order to enhance assembly-related techniques, we purchased
preferred stocks of VCI for US$5 million in December 2010. Our percentage of voting right in VCI is approximately 30.68%. Therefore, VCI became a related party of our company. VCIs board of directors resolved to file for bankruptcy protection
in July 2012. Accordingly, we recognized an impairment loss to all of its residual book value of NT$94.4 million.

AcSiP Technology
Corp.

In order to develop our System in Package (SiP) module business, we purchased 1.75 million common shares of AcSiP for
NT$50.75 million (US$1.68 million) and obtained 20% of the voting rights of AcSiP in May 2011. As a result of an increase in AcSiPs issued shares, our ownership share in AcSiP decreased to 11.99% as of December 31, 2013. We assess and
determine that we maintain significant influence over the investee through representation on and participation in AcSiPs board of directors, and therefore we continue to record the investment in AcSiP under the equity method.

Microcircuit Technology (S) Pte. Ltd.

In order to develop new generation substrates and increase substrate supply sources, we acquired 22,865,385 shares of MCT, a substrate supplier
located in Singapore, for US$20.5 million in July 2012. In December 2013, we invested another US$1.06 million and our total holdings increased to 24,039,552 shares. Our percentage of ownership in MCT remains at approximately 42.27%.

B. Significant Changes

unconsolidated or a consolidated basis for the remaining months of 2014. In addition, we cannot predict whether the demand for our services will continue to improve in the near future.

B. Memorandum and Articles of Association

The following statements summarize the material elements of our capital structure and the more important rights and privileges of our
shareholders conferred by Taiwan law and our articles of incorporation.

Objects and Purpose

The scope of business of our company as set forth in Article 2 of our articles of incorporation includes:

(a) The production, processing and purchase and sale of products, including IC, transistors, light emitting diode digital displays, light
emitting diode display lamps, liquid crystal clock cores, photo diodes, hybrid circuits, thin film circuits and thick film circuits; and

(b) The import and export of the products mentioned in the preceding paragraph.

Directors

The R.O.C.
Company Act and our articles of incorporation provide that our board of directors is elected by shareholders and is responsible for the management of our services. Our board of directors is composed of nine directors. The Chairman of our board is
elected by our directors. The Chairman presides at all meetings of our board of directors and also has the authority to represent us. The term of office for our directors is three years and our directors are elected by our shareholders by means of
cumulative voting. The last election for all of the directors and supervisors was held in June 2011. Upon the end of the term of the directors elected during the 2011 shareholders meeting, our board is required by the R.O.C. Company Act, the
Securities and Exchange Act and other relevant laws and regulations to consist of at least three directors, comprising not less than 20% of the total number of directors. In addition, our shareholders also elect three supervisors whose duties
include investigating our services and financial condition, inspecting corporate records, calling shareholders meetings when our board of directors does not or cannot convene a shareholders meeting or when such a meeting is necessary for
our benefit, representing us in negotiations with our directors and notifying our board of directors to cease acting in contravention of law, our articles of incorporation or the resolutions of our shareholders meetings. The supervisors cannot
concurrently serve as our directors or officers. A person may serve as our director or supervisor in his personal capacity or as the representative of one of our shareholder entities. A director or supervisor who serves as the representative of a
legal entity may be removed or replaced at any time, and the replacement director or supervisor may serve the remainder of the term of office of the replaced director or supervisor. Our audit committee consists of three independent auditors,
including Jing-Shan Aur, Ing-Dar Liu and Cheng-Chich Huang. In order to facilitate the function of our board of directors, our audit committee and board of directors have established procedures for the complaints pursuant to Rule 10A-3(b)(3) under
the Exchange Act and have established a means for communicating with the non-management members of our board of directors.

According to
the R.O.C. Company Act, a director who has a personal interest in a matter to be discussed at the meeting of the board of directors, the outcome of which may impair the companys interests, shall abstain from voting on such matter. Our articles
of incorporation also provide that the traveling expenses for all directors and supervisors shall be determined at the board of directors meeting based on common practice regardless of the profit or loss to our company. In addition, according
to our articles of incorporation, we should distribute no more than 1% of the balance of our earnings after deduction of payment of all taxes and dues, deduction of any past losses and allocation of 10% of our net income as a legal reserve as
remuneration to directors and supervisors. Our board of directors is authorized to determine the compensation for directors and supervisors by taking into consideration their respective contributions to our company as well as international industry
practice. Our articles of incorporation do not impose a mandatory retirement age limit for our directors. Furthermore, our articles of incorporation do not impose a shareholding qualification for each director; however, our articles of incorporation
require that our directors and supervisors hold our issued shares at the ratios as required by the regulatory authority.

Shares

As of March 31, 2014, our authorized share capital was NT$36.0 billion, divided into 3.6 billion shares, of which NT$31.16
billion was issued. As of March 31, 2014, no option rights remained outstanding. Other than our shares and ADSs, we do not have any other equity interests outstanding, including any preferential subscription rights, exchangeable debt securities
or warrants as of March 31, 2014. All shares presently issued are fully paid and in registered form, and existing shareholders are not obligated to contribute additional capital. The shares underlying the ADSs are fully paid, in registered form
and will not be obligated by any capital calls. We generally are not permitted to directly acquire our shares, except under limited circumstances as permitted by R.O.C. law.

New Shares and Preemptive Rights

New shares may only be issued with the prior approval of our board of directors. If our issuance of any new shares will result in any change in
our authorized share capital, we are required under R.O.C. law to amend our articles of incorporation and obtain approval of our shareholders in a shareholders meeting. We must also obtain the approval of, or submit a registration with, the
R.O.C. SFB and the Ministry of Economic Affairs. According to the R.O.C. Company Act, when a company issues capital stock for cash, 10% to 15% of the issue must be offered to its employees. In addition, if a listed company intends to offer new
shares for cash, at least 10% of the issue must also be offered to the public pursuant to the Securities and Exchange Law. This percentage can be increased by a resolution passed at a shareholders meeting, which will reduce the number of new
shares in which existing shareholders may have preemptive rights. Unless the percentage of the shares offered to the public is increased by a resolution, existing shareholders of the company have a preemptive right to acquire the remaining 75% to
80% of the issue in proportion to their existing shareholdings.

Shareholders

We only recognize persons registered in our register as our shareholders. We may set a record date and close our register of shareholders for
specified periods to determine which shareholders are entitled to various rights pertaining to our shares.

Transfer of Shares

Under the R.O.C. Company Act, a public company, such as us, may issue individual share certificates, one master certificate or scripless shares
to evidence common shares. Shares in registered form are transferred by endorsement and delivery of the related share certificates. Transferees must have their names and addresses registered on our register in order to assert shareholders
rights against us. Our shareholders are required to file their respective specimen seals with our share registrar, Chinatrust Commercial Bank.

Shareholders Meetings

We are required to hold an annual ordinary shareholders meeting once every fiscal year and within six months after the end of each fiscal
year. Our board of directors may convene an extraordinary meeting whenever the directors think fit, and they must do so if requested in writing by shareholders holding not less than 3% of our paid-in share capital who have held these shares for more
than a year. In addition, any of our supervisors may convene a shareholders meeting when our board of directors do not or cannot convene a shareholders meeting and/or when such a meeting is necessary for our benefit. At least 15 days
advance written notice must be given of every extraordinary shareholders meeting and at least 30 days advance written notice must be given of every annual ordinary shareholders meeting. Unless otherwise required by law or by our articles
of incorporation, voting for an ordinary resolution requires an affirmative vote of a simple majority of those present. A distribution of cash dividends would be an example of an ordinary resolution. The R.O.C. Company Act also provides that in
order to approve certain major corporate actions, including but not limited to any amendment of our articles of incorporation, dissolution, merger or spin-off, the transfer of the whole or major part of the business or assets, removing directors or
the distribution of any stock dividend, a special resolution may be adopted by the holders of at least two-thirds of our shares represented at a meeting of shareholders at which holders of at least a majority of our issued and outstanding shares are
present. However, if we are the controlling company and hold not less than 90% of our subordinate companys outstanding shares, our merger with the subordinate company can be approved by a board resolution adopted by majority consent at a
meeting with two-thirds of our directors present without shareholders approval.

Voting Rights

Except for treasury shares, each share is generally entitled to one vote. Except as otherwise provided for by law or by our articles of
incorporation, a resolution can be adopted by the holders of a simple majority of the total issued and outstanding shares represented at a shareholders meeting. The quorum for a shareholders meeting to discuss the ordinary resolutions is
a majority of the total issued and outstanding shares. The election of directors and supervisors by our shareholders may be conducted by means of cumulative voting or other voting mechanisms adopted in our articles of incorporation. In all other
matters, a shareholder must cast all his votes in the same manner when voting on any of these matters.

Our shareholders may be
represented at an ordinary or extraordinary shareholders meeting by proxy if a valid proxy form is delivered to us five days before the commencement of the ordinary or extraordinary shareholders meeting. Voting rights attached to our
shares exercised by our shareholders proxy are subject to the proxy regulation promulgated by the R.O.C. SFB.

Any shareholder who
has a personal interest in a matter to be discussed at our shareholders meeting, the outcome of which may impair our interests, shall not vote or exercise voting rights on behalf of another shareholder on such matter.

Any holder of our ADSs generally will not be able to exercise voting rights on the shares underlying its holding of ADSs on an individual
basis.

Dividends and Distributions

We may distribute dividends in any year in which we have current or retained earnings (excluding reserves). Before distributing a dividend to
shareholders, we must recover any past losses, pay all outstanding taxes and set aside a legal reserve equivalent to 10% of our net income until our legal reserve equals our paid-in capital.

At the shareholders annual ordinary meeting, our board of directors submits to the shareholders for their approval proposals for the
distribution of a dividend or the making of any other distribution to shareholders from our net retained earnings or reserves. Dividends are paid to shareholders proportionately. Dividends may be distributed either in cash or in shares or a
combination of cash and shares, as determined by the shareholders at such meeting. Distribution of stock dividends requires approvals from the R.O.C. SFB and the Ministry of Economic Affairs, as necessary.

Our articles of incorporation provide that our earnings after payment of all income taxes and deduction of any past losses shall be
distributed as follows:



| |  |  | allocation of 10% of our net income as legal reserve; and
| | - |  | ---------------------------------------------------------



| |  |  | payment of no more than 1% of the balance after deducting the 10% legal reserve as remuneration to our directors and supervisors. The remaining amount may be distributed or reserved in a ratio of 10% and 90%,
respectively, to our employees as their bonuses and to our shareholders as their dividends.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For dividend distributions, the
surplus dividend policy will be adopted based on the future operational planning, business development, capital expenditure budget and requirement of capital fund.

Distribution of dividends may be made by cash dividends or by stock dividends, provided that the percentage of cash dividends shall exceed 50%
of total distributed dividends, and the plan of distribution shall be proposed by the Board of Directors and shall be implemented after the distribution plan is approved by our shareholders meetings.

In addition to permitting dividends to be paid out of net income, we are permitted under the R.O.C. Company Act to make distributions to our
shareholders of additional shares by capitalizing reserves, including the legal reserve and capital surplus of premiums from issuing stock and earnings from gifts received if we do not have losses. However, the amount of legal reserve that may be
used to distribute cash dividends shall be limited to the portion of the reserve balance that exceeds 25% of capital stock.

Acquisition of Our Shares by Us

An R.O.C. company may not acquire its own common shares except under certain exceptions provided in the R.O.C. Company Act or the R.O.C.
Securities and Exchange Law.

Under the Securities and Exchange Law, we may, by a board resolution adopted by majority consent at a
meeting with two-thirds of our directors presence, purchase up to 10% of our issued shares on the Taiwan Stock Exchange or by a tender offer, in accordance with the procedures prescribed by the R.O.C. SFB, for the following purposes:



| |  |  | to transfer shares to our employees;
| | - |  | ------------------------------------



| |  |  | to transfer upon conversion of bonds with warrants, preferred shares with warrants, convertible bonds, convertible preferred shares or certificates of warrants issued by us; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if necessary, to maintain our credit and our shareholders interests; provided that the shares so purchased shall be cancelled thereafter.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------

In addition, we may not spend more than the aggregate amount of the retained earnings, the premium from issuing stock and the realized portion
of the capital reserve to purchase our shares.

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

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 Act.

Other Rights of Shareholders

Under the R.O.C. Company Act, dissenting shareholders are entitled to appraisal rights in the event of a spin-off or a merger and various other
major corporate actions. Dissenting shareholders may request us to redeem all their shares at a fair price to be determined by mutual agreement. If no agreement can be reached, the valuation will be determined by a court. Subject to applicable law,
dissenting shareholders may, among other things, exercise their appraisal rights by notifying us before the related shareholders meeting and /or by raising and registering their dissent at the shareholders meeting.

One or more shareholders who have held more than 3% of the issued and outstanding shares for more than one year may require our board of
directors to call an extraordinary shareholders meeting by sending a written request to our board of directors.

In addition, the
R.O.C. Company Act allows shareholders holding 1% or more of the total issued shares of a company to submit, during the period of ten days or more prescribed by the company, one proposal in writing containing no more than three hundred Chinese
characters for discussion at the annual ordinary shareholders meeting.

Voting of Deposited Securities

A holder may direct the exercise of voting rights regarding the shares represented by the ADSs only pursuant to the deposit agreement as
described below and applicable R.O.C. law. See Risk factorsHolders of our ADSs will not have the same voting rights as the holders of our shares, which may affect the value of your investment.

Except as described below, a holder generally will not be able to exercise voting rights attaching to the shares on an individual basis.
According to the R.O.C. Company Act, a shareholders voting rights must, as to all matters brought to a vote of shareholders, other than the election of directors and/or supervisors, be exercised as to all shares held by the shareholder in the
same manner. Accordingly, the voting rights of the shares represented by ADSs must be exercised collectively in the same manner, except in the case of an election of directors and/or supervisors, which may be conducted by means of cumulative voting
or other mechanisms adopted in our articles of incorporation. Pursuant to R.O.C. Company Act and our articles of incorporation, the election of directors and/or supervisors is by means of cumulative voting.

By accepting and continuing to hold ADSs or any interest therein, a holder will authorize and direct the depositary to appoint our chairman or
the chairmans designee as his representative to exercise the voting rights attaching to the shares underlying the ADSs.

Once
notified of a shareholders meeting, the depositary will, subject to the terms of the deposit agreement, fix a record date for determining the owners entitled to receive information about this meeting. The depositary will mail to the owners:



| |  |  | the notice of the meeting sent by us; and
| | - |  | -----------------------------------------



| |  |  | a statement that the owners will be entitled to instruct the depositary or its nominee as to the exercise of the voting rights.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------

If the depositary timely receives voting instructions from holders of at least 51% of the outstanding ADSs to vote in the same manner on a
resolution, including election of directors and/or supervisors, the depositary will cause all of the shares underlying the outstanding ADSs to be voted in the manner instructed. If for any reason, other than our failure to provide timely notice to
the depositary of a shareholders meeting, the depositary does not receive timely instructions from holders of at least 51% of all ADSs outstanding to vote in the same manner on a resolution, including a resolution for the election of directors
and/or supervisors, the holders of all ADSs outstanding shall be deemed, subject to our satisfying the applicable requirements of the deposit agreement, to have authorized and directed the depositary to give a discretionary proxy to the chairman of
our board of directors, or the chairmans designee, to vote the shares on deposit in respect of their ADSs in his discretion, which may not be in the interest of the holders of ADSs.

An ADS holder will not be able to exercise cumulative voting rights on an individual basis in the elections of directors and/or supervisors
under the deposit agreement. This means that if at least 51% of the votes represented by outstanding ADSs are cast for a particular director or supervisor for a particular open position in an election, the depositary shall, subject to the terms of
the deposit agreement, cause all of the shares underlying the outstanding ADSs to be voted in favor of the director or supervisor.

By
accepting and continuing to hold ADSs or any interest therein, a holder 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 a holder will receive notice of shareholders meetings sufficiently prior to the date
established by the depositary for receipt of instructions to enable him to give timely voting instructions.

C. Material Contracts

Immunity Agreement with Freescale Semiconductor, Inc.

We entered into a license agreement with Motorola Inc., or Motorola, in November 1996 under which Motorola licensed to us the technology for
ball grid array as well as any future technology relating to ball grid array packages.

In April 2004, Motorola spun off its semiconductor
product business into a subsidiary Freescale Semiconductor, Inc. Motorola has assigned this agreement to Freescale Semiconductor, Inc., and Freescale Semiconductor, Inc. has assumed all of its rights, duties and obligations under the agreement, in
connection with the spin-off. This license will expire in December 2015.

License Agreement with Flip Chip International, L.L.C.

We entered into a license agreement in November 1999, under which Flip Chip International licensed to us the package design technology
that enables us to attach silicon dies directly to substrates using solder bumping rather than wire bonding technology. Under the original terms of this agreement, we made royalty payments based on the number of bumped wafers produced. This original
license was set to expire in November 2009.

In December 2008, we amended our license agreement with Flip Chip International, in which for
a one-time payment, Flip Chip International granted us a perpetual license for the package design technology.

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

On
September 30, 2003, the Executive Yuan amended the Regulations Governing Investment in Securities by Overseas Chinese and Foreign Nationals, or the Investment Regulations, under which the Qualified Foreign Institutional Investors,
or QFII, designations have been abolished and the restrictions on foreign portfolio investors have been revised. According to the Investment Regulations, Foreign Institutional Investor means an entity which is incorporated under the laws
of countries other than the R.O.C. or the branch of a foreign entity which is established within the territory of the R.O.C., and Foreign Individual Investor means an overseas Chinese or a foreign natural person. In addition, the
Investment Regulations also lifted some restrictions and simplified procedures of investment application.

On April 30, 2009, the FSC
promulgated regulations allowing qualified domestic institutional investors, or QDIIs, under P.R.C. regulations and certain other P.R.C. persons to invest in the securities of R.O.C. companies. However, prior approval from the Investment Commission
of the R.O.C. Ministry of Economic Affairs is required for a P.R.C. persons ownership of 10% or more of the issued and outstanding shares of a listed R.O.C. company.

Foreign Investment in Taiwan Securities Market

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

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

##### Table of Contents

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



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



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



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



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



| |  |  | Except for certain specified industries, such as telecommunications, investments in Taiwan-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.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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

Foreign Investment Approval

Other than:



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



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



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

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

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

##### Table of Contents

The FSC announced on April 30, 2009 the Regulations Governing Mainland Chinese
Investors Securities Investments, or the P.R.C. Regulations. According to the P.R.C. Regulations, a QDII is allowed to invest in Taiwan Securities (including up to 10% shareholding of a Taiwan 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 Taiwan securities market with the amount approved by the Taiwan Stock Exchange. There is no assurance that in the future, there will not be further restrictions or
prohibitions imposed on P.R.C. persons (including QDIIs) from investing in certain industries in Taiwan. In addition to investments permitted under the P.R.C. Regulations, P.R.C. investors other than QDII are prohibited from making investments in a
Taiwan 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 Taiwan company.

In addition to the general restriction against direct investment by P.R.C. investors in securities of Taiwan companies, P.R.C. investors may
only invest in certain industries in the Positive List, as promulgated by the R.O.C. Executive Yuan in June of 2009. In the semiconductor packaging and testing industry, P.R.C. investors are allowed to invest up to 10% in existing Taiwan companies,
and up to 50% in new ventures, but are not allowed to be controlling shareholders of the Taiwan companies in which they invest.

Depositary Receipts

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

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

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

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



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



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



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



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

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



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



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

##### Table of Contents

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

Exchange Controls

Taiwans Foreign Exchange Control Statute and regulations provide that all foreign exchange transactions must be executed by banks
designated to handle foreign exchange transactions by the FSC 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. All foreign currency needed for the importation of merchandise and services may be purchased freely from the designated foreign exchange banks.

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

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

E. Taxation

R.O.C. Tax Considerations

The following summarizes the principal R.O.C. tax consequences of owning and disposing of ADSs and shares for non-residents of Taiwan.
Investors in our ADSs are advised to consult their own tax advisers as to United States, Taiwan or other tax consequences of the purchase, ownership and disposition of ADSs.

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. The summary description 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 their particular R.O.C. tax consequences from owning the
ADSs.

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.

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.

##### Table of Contents

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 is currently payable at rate of 10%. Gift tax is payable at 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.

Certain R.O.C. estate and gift taxes may be imposed on holders of ADSs. Holders should consult their own tax advisor regarding the effect of
such taxes on their particular situation.

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
Australia, Belgium, Denmark, France, Gambia, Germany, Hungary, India, Indonesia, Israel, Macedonia, Malaysia, the Netherlands, New Zealand, Paraguay, Senegal, Singapore, Slovakia, South Africa, Swaziland, Sweden, Switzerland, UK and Vietnam which
may limit the rate of R.O.C. withholding tax on dividends paid with respect to common shares in R.O.C. companies. It is unclear whether ADS holders will be considered holders of 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.

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

The following is a summary of the material U.S. federal income tax consequences for beneficial owners of our shares or ADSs that hold the
shares or ADSs as capital assets, and that are U.S. holders and non-residents of the R.O.C. You are a U.S. holder if you are, for U.S. federal income tax purposes, any of the following:



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



| |  |  | a corporation (or other entity treated as a corporation) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



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



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

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



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



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



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



| |  |  | a tax-exempt organization;
| | - |  | --------------------------



| |  |  | a regulated investment company;
| | - |  | -------------------------------



| |  |  | a real estate investment trust;
| | - |  | -------------------------------



| |  |  | a person liable for alternative minimum tax;
| | - |  | --------------------------------------------



| |  |  | a person holding shares or ADSs as part of a hedging, integrated or conversion transaction, constructive sale or straddle;
| | - |  | --------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | a partnership or other pass-through entity for U.S. federal income tax purposes;
| | - |  | --------------------------------------------------------------------------------



| |  |  | a person owning, actually or constructively, 10% or more of our voting stock; or
| | - |  | --------------------------------------------------------------------------------



| |  |  | a U.S. holder whose functional currency is not the United States dollar.
| | - |  | --------------------------------------------------------------------------

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

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

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

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

Taxation of Dividends

Except as discussed below with respect to the passive foreign investment company rules, the amount of distributions you receive on your shares
or ADSs, including net amounts withheld in respect of R.O.C. withholding taxes, will generally be treated as dividend income to you if the distributions are made from our current and accumulated earnings and profits as calculated according to U.S.
federal income tax principles. Such income (including any R.O.C. taxes withheld) will be includible in your gross income as ordinary income on the day you actually or constructively receive it, which in the case of an ADS will be the date actually
or constructively received by the depositary. The amount of any distribution of property other than cash will be the fair market value of such property on the date it is distributed. You will not be entitled to claim a dividend received deduction
with respect to distributions you receive from us.

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

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

Subject to certain limitations under the Code, you may be entitled to a credit or deduction
against your federal income tax liability for the net amount of any R.O.C. taxes that are withheld from dividend distributions made to you. The election to receive a credit or deduction must be made annually, and applies to all foreign taxes for the
applicable tax year. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends we pay with respect to the shares or ADSs will generally be considered passive
category income from sources outside the U.S. Furthermore, you will not be allowed a foreign tax credit for foreign taxes imposed on dividends paid on the shares or ADSs if you (1) have held the shares or ADSs for less than a specified minimum
period during which you are not protected from risk of loss, or (2) are obligated to make payments related to the dividends. The rules governing the foreign tax credit are complex. We therefore urge you to consult your tax advisor regarding the
availability of the foreign tax credit under your particular circumstances.

##### Table of Contents

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

It is possible that pro rata distributions of shares or ADSs to all shareholders may be made in a manner that is not subject to U.S. federal
income tax. In the event that such distributions are tax-free, the basis of any new shares or ADSs so received will generally be determined by allocating the U.S. holders basis in the old shares or ADSs between the old shares or ADSs and the
new shares or ADSs, based on their relative fair market values on the date of distribution. Any such distributions generally would not result in foreign source income to you. Consequently, you may not be able to use the foreign tax credit associated
with any R.O.C. withholding tax imposed on such distributions unless you can use the credit against United States federal income tax due on other foreign source income in the appropriate category for foreign tax credit purposes. You should consult
your own tax advisors regarding all aspects of the foreign tax credit.

Taxation of Capital Gains

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

If you pay
any R.O.C. securities transaction tax, such tax is not treated as an income tax for U.S. federal income tax purposes, and therefore will not be a creditable foreign tax for U.S. federal income tax purposes. However, subject to limitations under the
Code, such tax may be deductible. You are urged to consult your tax advisors regarding the U.S. federal income tax consequences of these taxes.

Passive Foreign Investment Company

Based on the composition of our income and valuation of our assets, including goodwill, we do not believe we were a passive foreign investment
company, or PFIC, for 2013 and do not expect to become one in the future, although there can be no assurance in this regard.

In general,
a non-U.S. company is considered a PFIC for any taxable year if either:



| |  |  | at least 75% of its gross income is passive income, which generally includes income derived from certain dividends, interest, royalties and rents (other than royalties and rents derived in the active conduct of a trade
or business or not derived from a related person), annuities and certain property transactions; or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | at least 50% of the value of its assets is attributable to assets that produce or are held for the production of passive income.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------

The 50% of value test is based on the average of the value of our assets for each quarter during the taxable year. If we own at least 25% by
value of another companys stock, we will be treated, for purposes of the PFIC rules, as owning our proportionate share of the assets and receiving our proportionate share of the income of that company.

The determination of whether we are a PFIC is based on a current valuation of our assets, including goodwill. In calculating goodwill, we have
valued our total assets based on our total market value, which is based on the market value of our shares and is subject to change.

In
addition, the determination of whether we are a PFIC is made annually. Accordingly, it is possible that we may become a PFIC in the current or any future taxable year due to changes in our asset or income composition.

##### Table of Contents

If we are a PFIC for any taxable year during which you hold our shares or ADSs, you will be
subject to special tax rules with respect to any excess distribution that you receive and any gain you realize from a sale or other disposition (including a pledge) of our shares or ADSs. Distributions you receive in a taxable year that
are greater than 125% of the average annual distributions you received during the shorter of the three preceding taxable years or your holding period for our shares or ADSs will be treated as excess distributions. Under these special tax rules:



| |  |  | the excess distribution or gain will be allocated ratably over your holding period for our shares or ADSs;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we were a PFIC, will be treated as ordinary income; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to each other year will be subject to tax at the highest tax rate in effect for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax
attributable to each such year.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If you hold our shares or ADSs in any year in which we are a PFIC, you will generally be
required to file Internal Revenue Service Form 8621.

If we are a PFIC for any taxable year in which you hold our shares or ADSs and any
of our non-U.S. subsidiaries is also a PFIC, a U.S. holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the application of these rules. You are urged to consult your tax advisors
about the application of the PFIC rules to any of our subsidiaries.

In certain circumstances, a U.S. holder, in lieu of being subject to
the PFIC rules discussed above, may make an election to include gain on the stock of a PFIC as ordinary income under a mark-to-market method provided that such stock is regularly traded on a qualified exchange. Under this method, any difference
between the stocks fair market value and its adjusted basis at the end of the year is accounted for by either an inclusion in income or a deduction from income, as described below. Under current U.S. Treasury Department guidance, the
mark-to-market election may be available to you because the ADSs are listed on the NASDAQ which constitutes a qualified exchange, although there can be no assurance that the ADSs will be regularly traded for the purposes of the
mark-to-market election. You should also note that only the ADSs and not the shares are listed on the NASDAQ. The shares are listed on the Taiwan Stock Exchange, which must meet certain trading, listing, financial disclosure and other requirements
to be treated as a qualified exchange under applicable U.S. Treasury regulations for purposes of the mark-to-market election, and no assurance can be given that the shares will be regularly traded for purposes of the mark-to-market
election.

If you make an effective mark-to-market election, you will include in income each year as ordinary income the excess of the
fair market value of your shares or ADSs at the end of the year over your adjusted tax basis in the shares or ADSs. You will be entitled to deduct as an ordinary loss each year the excess of your adjusted tax basis in the shares or ADSs over their
fair market value at the end of the year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. If you make an effective mark-to-market election, in each year that we are a PFIC any gain
you recognize upon the sale or other disposition of your shares or ADSs will be treated as ordinary income and any loss will be treated as ordinary loss, but only to the extent of the net amount of previously included income as a result of the
mark-to-market election.

Your adjusted tax basis in the shares or ADSs will be increased by the amount of any income inclusion and
decreased by the amount of any deductions under the mark-to-market rules. If you make a mark-to-market election, it will be effective for the taxable year for which the election is made and all subsequent taxable years, unless the shares or ADSs are
no longer regularly traded on a qualified exchange or the Internal Revenue Service consents to the revocation of the election. You should consult your tax advisor about the availability of the mark-to-market election, and whether making the election
would be advisable in your particular circumstances.

Alternatively, a U.S. holder of shares or ADSs in a PFIC can sometimes avoid the
rules described above by electing to treat the PFIC as a qualified electing fund under section 1295 of the Code. This option is not available to you because we do not intend to comply with the requirements necessary to permit you to make
this election.

U.S. holders who are individuals will not be eligible for reduced rates of taxation on any dividends received from us if
we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year. You should consult your own tax advisors concerning the U.S. federal income tax consequences of holding our shares or ADSs if we are considered a
PFIC in any taxable year.

Information Reporting and Backup Withholding

In general, unless you are an exempt recipient, information reporting will apply to dividends in respect of the shares or ADSs and to the
proceeds from the sale, exchange or redemption of your shares or ADSs that are paid to you within the United States (and in some cases, outside of the United States). Additionally, if you fail to provide your taxpayer identification number, or fail
either to report in full dividend and interest income or to make the necessary certifications of other exempt status, you may be subject to backup withholding.

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

|Item 11. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

Market risk is the risk of
loss related to adverse changes in market prices, including interest rates and foreign exchange rates, of financial instruments. We are exposed to various types of market risks, including changes in interest rates, foreign currency exchange rates
and commodity price risk, in the normal course of business.

Foreign Exchange Risk

Substantial portions of our revenues and expenses are denominated in currencies other than the NT dollar. In 2013, sales in the amount of
US$1,987 million were denominated in U.S. dollars. In 2013, material purchases in the amounts of US$509 million and ¥4,985 million were denominated in U.S. dollars and Japanese yen, respectively. As of December 31, 2013, we had
certificates of deposit, bank deposits and accounts receivable denominated in U.S. dollars of US$ 617 million. As of December 31, 2013, we also had accounts payable and other liabilities denominated in U.S. dollars and the Japanese yen of US$
631 million and of ¥3,034 million, respectively. Our foreign currency revenues in general exceed our foreign currency expenses. We use the policy of natural hedging to reduce our foreign exchange exposure arising out of changes in the
rates of exchange among the Japanese Yen, the U.S. dollar and the NT dollar. The table below presents our financial instruments with foreign exchange risk as of December 31, 2013:

Interest Rate Risk

Our major market risk exposure is changing interest rates. Our exposure to market risk for changes in interest rates relates primarily to our
long-term debt obligations. We primarily enter into debt obligations to support general corporate purposes including capital expenditures and working capital needs. We have not entered into any interest rate swaps, caps or any contracts hedge to
modify our exposure to interest rate movements.

As of December 31, 2013, we had NT$18,540 million (US$621.5 million), exclusive of
loan arrangement fees of NT$30 million, of long-term borrowings. Our future interest expenses on our long-term borrowings may increase or decrease due to changes in market interest rates. Our long-term borrowings had a weighted average interest rate
of 1.4302% per annum during 2013. The first and second credit facilities led by Mega International Commercial Bank are repayable in 6 semi-annual installments starting from April 2013 and February 2015, respectively. The third credit facility
led by China Development Industrial Bank is expiring and repayable in December 2016.

Commodity Price Risk

The price of gold wire has been volatile and has fluctuated with the spot price of gold in recent years. We generally have not entered into
long-term supply agreements and purchase our raw materials on a purchase order basis at the prevailing market price. In addition, we do not employ financial instruments to hedge such commodity price risk. Therefore, in order to effectively mitigate
the risk, we have continued to implement measures to reduce our dependency on gold wire, such as the development of copper wire bonding process.

Depositary Charges

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



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



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



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



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



| |  |  | such fees and expenses as are incurred by the depositary in connection with compliance with exchange control regulations and other regulatory requirements applicable to common shares, deposited securities, ADSs and
ADRs; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

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

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

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

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

Payments by Depositary

In 2013, we received the following payments (subject to applicable withholding tax) from Citibank, N.A., the depositary bank for our ADR
program:

Disclosure Controls and Procedures

As of December 31, 2013, an evaluation has been carried out under the supervision and with the participation of our management, including
our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Securities
Exchange Act of 1934, as amended. Disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within
the time periods specified in the SECs rules and forms and that such information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions
regarding the required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures.
Disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. Based upon the Companys evaluation, the Companys Chief Executive Officer and Chief Financial Officer have concluded that the
Companys disclosure controls and procedures are effective at a reasonable assurance level as of December 31, 2013.

Managements Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in
Rule 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of
records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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 its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2013 utilizing the criteria set
forth in 1992 by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

Based on this assessment, our management concluded that our internal control over financial reporting was effective as of December 31,
2013. The effectiveness of internal control over financial reporting has been audited by PricewaterhouseCoopers, Taiwan, an independent registered public accounting firm, which also audited our consolidated financial statements for the year ended
December 31, 2013, as stated in their report included on page F-2.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the year ended December 31, 2013
that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

|Item 16G. | Corporate Governance
|--------- | --------------------

In general, corporate governance principles for Taiwanese
companies are set forth in the R.O.C. Company Act, the R.O.C. Securities and Exchange Act and, to the extent they are listed on the Taiwan Stock Exchange, listing rules of the Taiwan Stock Exchange. Corporate governance principles under provisions
of R.O.C. law may differ in significant ways to corporate governance standards for U.S. NASDAQ-listed companies. Under the latest amendment to the NASDAQ Listing Rule 5615, foreign private issuers are permitted to follow certain home country
corporate governance practices in lieu of the requirements of the NASDAQ corporate governance rules. Under the amendment, foreign private issuers must disclose alternative home country practices they follow. The following are the requirements of the
NASDAQ corporate governance rules we do not follow and the home country practices we follow.

Under the NASDAQ Listing Rule 5605(b)(1), a
majority of the board of directors must comprise of independent directors. We have three independent directors out of a total of nine directors on our board. Our standards in determining director independence substantially comply with the NASDAQ
requirements, which include detailed tests for determining director independence. In Taiwan, in order to strengthen corporate governance of Taiwanese companies, the R.O.C. Securities and Exchange Act Article 14-2 provides that public companies may
appoint independent directors in accordance with its articles of incorporation, as long as it is compliant with related requirements and regulations of the R.O.C. The government authority, however, may require a company to appoint two or more
independent directors, who shall account for one-fifth or more of its total directors, depending on such companys scale, shareholder structure, type of operations and other essential factors.

Under NASDAQ Listing Rule 5605(b)(2), the company is required to have regularly scheduled meetings at which only independent directors are
present. We do not hold executive sessions of non-management directors as the election of independent directors is not required by the R.O.C. Company Act. However, once our independent directors are elected, they will participate in committee
meetings of which they are committee members. In particular, we expect our independent directors to serve on our audit committee. Our audit committee will meet regularly.

NASDAQ Listing Rule 5605(d) requires that compensation of the chief executive officer of the company must be determined, or recommended to the
board, either by a majority of the independent director or an independent compensation committee. We currently follow the practice under the R.O.C. Securities and Exchange Act, as amended on November 24, 2010, which requires all publicly listed
companies in the R.O.C., including our company, to establish a remuneration committee for directors, supervisors and managers compensation, which includes salary, stock options and other rewards. On March 18, 2011, the FSC promulgated
Regulations Governing the Appointment and Exercise of Powers by the Remuneration Committee of a Company Whose Stock is Listed on the Stock Exchange or Traded Over the Counter, according to which publicly listed companies of our size were
required to establish a remuneration committee composed of no less than three members appointed by the board of directors. Such committee members must meet certain professional qualification requirements and must not have served as an employee or
non-independent director of the company in the two years prior to their appointment. Pursuant to such regulations, on August 25, 2011, we established a remuneration committee comprised of William W. Sheng, Professor of the National Taichung
Institute of Technology, Tsai-Ding Lin, Professor of Tunghai University, and Jing-Shan Aur, one of our independent directors.

Under
NASDAQ Listing Rule 5605(e), director nominees must either be selected, or recommended for the Boards selection, either by a majority of the independent directors or an independent nominations committee. The R.O.C. Company Act expressly grants
the power of nomination to the shareholders, as well as to the board of directors. Under the R.O.C. Company Act and the interpretations thereof, candidates to serve as directors are nominated either by the board of directors prior to the
shareholders meeting or by the shareholders during the election of the director. Therefore, the requirement of a nominations committee is in conflict with the R.O.C. Company Act. We currently follow the home country practice.

##### Table of Contents

Under NASDAQ Listing Rule 5635(c), each issuer shall require shareholder approval when a stock
option or purchase plan is to be established or materially amended or other equity compensation arrangement made or materially amended, pursuant to which stock may be acquired by officers, directors, employees, or consultants. Under the
corresponding domestic requirements in the R.O.C. Company Act and the R.O.C. Securities and Exchange Act, shareholders approval is required for the distribution of employee bonuses in the form of stock, while the board of director has
authority, subject to the approval of the R.O.C. SFB, to approve employee stock option plans and to grant options to employees pursuant to such plans. We follow the home country practice. R.O.C. law provides for specific safeguards on employee stock
option grants. Options granted under the plans are subject to certain statutory volume limitations. Under the R.O.C. Company Act, the directors of a company may not receive stock options because they are not considered employees of the
company.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

Siliconware Precision Industries Co., Ltd.

In
our opinion, the accompanying consolidated balance sheets and the related consolidated statements of comprehensive income, of changes in equity and of cash flows present fairly, in all material respects, the financial position of Siliconware
Precision Industries Co., Ltd. and its subsidiaries (the Company) at December 31, 2013, 2012 and January 1, 2012, and the results of their operations and their cash flows for each of the two years in the period ended
December 31, 2013 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also, in our opinion, the Company maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Companys
management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Managements
Annual Report on Internal Control Over Financial Reporting appearing under Item 15. Our responsibility is to express opinions on these financial statements and on the Companys internal control over financial reporting based on our
integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States) and International Standards on Auditing. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements
included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement
presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and
operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our
opinions.

A companys internal control over financial reporting is a process designed 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
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) 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 (iii) 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 its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

|IFRS 9, Financial Instruments               |  | The standard addresses the classification, measurement and recognition of financial assets and financial liabilities. IFRS 9 was issued to replace the parts of IAS 39 that relate to the classification and measurement of financial
instruments. It requires financial assets to be classified into two measurement categories: those measured as at fair value and those measured at amortised cost. The determination is made at initial recognition. The classification depends on the
entitys business model for managing its financial instruments and the contractual cash flow characteristics of the instrument. For financial liabilities, the standard retains most of the IAS 39 requirements. The main change is that, in cases
where the fair value option is taken for financial liabilities, the part of a fair value change due to an entitys own credit risk is recorded in other comprehensive income rather than the income statement, unless this creates an accounting
mismatch. |  | January 1, 2015

The Company and its subsidiaries (together, the Group) is assessing the potential impact of the new
standards, interpretations and amendments above and has not yet been able to reliably estimate their impact on the consolidated financial statements.



| | B. | New Standards and Interpretations Adopted
| | -- | -----------------------------------------

It is the first-time that the Group has
adopted International Financial Reporting Standards. All the new effective standards and interpretations are included and no early adoption is elected.



|4. | Summary of Significant Accounting Policies
|-- | ------------------------------------------

The accompanying consolidated financial
statements are prepared in conformity with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board. The Company determined to adopt the IFRS for annual periods beginning on
January 1, 2013. The transition date to IFRS from its previous generally accepted accounting principles (GAAP) was January 1, 2012. Prior to the adoption of IFRS, the Company prepared the consolidated financial statements in
accordance with GAAP of the Republic of China and Rules Governing the Preparation of Financial Reports by Securities Issuers.

SILICONWARE PRECISION INDUSTRIES CO., LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(EXPRESSED IN THOUSANDS OF NEW TAIWAN DOLLARS, EXCEPT EARNINGS PER SHARE)



The Company disclosed the first consolidated financial statements prepared in accordance with
IFRS, including IFRS 1, First-time Adoption of International Financial Reporting Standards. An explanation of how the transition to IFRS has affected the consolidated financial statements is provided in note 37.



|(1) | Basis of Preparation
|--- | --------------------

The consolidated financial statements have been prepared in
accordance with International Financial Reporting Standards and the interpretations of the IFRS interpretations committee (IFRIC). The consolidated financial statements have been prepared under the historical cost convention, as modified
by the available-for-sale financial assets at fair value. The preparation requires the use of certain critical accounting estimates and also requires management to exercise its judgment in the process of applying the accounting policies. The areas
involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in note 5.



|(2) | Principles of Consolidation
|--- | ---------------------------

Pursuant to IFRS 10, Consolidated financial
statements, subsidiaries are those entities controlled by the Company or its subsidiaries. The Company controls an entity when the Company is exposed to, or has right to, variable returns from its involvement with the entity and has the
ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

Inter-company transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also
eliminated. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.

|(4) | Foreign Currency Translation
|--- | ----------------------------



| | A. | Convenience Translation into US Dollars
| | -- | ---------------------------------------

The Group maintains its accounting records and
prepares its financial statements in New Taiwan (NT) dollars. The United States (US) dollar amounts disclosed in the 2013 financial statements are presented solely for the convenience of the reader and were translated at the
rate of NT$29.83 (in dollars) to US$1.00 (in dollars), which was the noon buying rate as certified for customs purposes by the Federal Reserve Bank of New York on December 31, 2013 as the last quoted rate at the balance sheet date. Such
translation amounts are unaudited and should not be construed that the NT dollar amounts represent, or have been, or could be, converted into US dollars at that or any other rate.



| | B. | Items included in the financial statements of each of the Groups entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency). The
consolidated financial statements are presented in New Taiwan Dollar (NTD), which is the presentation currency of the Group and the functional currency of the Company.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions where items are re-measured. Foreign exchange gains and losses resulting
from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized as other (losses)/gains in the income statement.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | D. | Translation differences on non-monetary financial assets and liabilities such as equities held at fair value through profit or loss are recognized in profit or loss as part of the fair value gain or loss. Translation
differences on non-monetary financial assets, such as equities classified as available-for-sale, are included in other comprehensive income.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | E. | The results and financial position of the Group entities that have a functional currency different from the presentation currency are translated into the presentation currency. Assets and liabilities for each balance
sheet presented are translated at the closing rate at the date of that balance sheet, income and expenses for each income statement are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative
effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on the dates of the transactions), and all resulting exchange differences are recognized in other comprehensive income. Those
differences would be recorded as gain or loss of disposal of investments in income statement if disposed.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) | Acquisition Method for Business Combination
|--- | -------------------------------------------



| | A. | The Company applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities incurred to
the former owners of the acquiree and the equity interests issued by the Company. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Identifiable assets acquired and
liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | Acquisition-related costs are expensed as incurred.
| | -- | ---------------------------------------------------



| | C. | If the business combination is achieved in stages, the acquisition date carrying value of the acquirers previously held equity interest in the acquiree is re-measured to fair value at the acquisition date; any
gains or losses arising from such re-measurement are recognized in profit or loss.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | D. | Any contingent consideration to be transferred by the Company is recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration that is deemed to be an asset or
liability is recognized in accordance with IAS 39 either in profit or loss or as a change to other comprehensive income. Contingent consideration that is classified as equity is not re-measured, and its subsequent settlement is accounted for within
equity.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | E. | The excess of the consideration transferred and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets acquired is recorded as goodwill. If the
total of consideration transferred, non-controlling interest recognized and previously held interest measured is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized
directly in the income statement.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(6) | Classification of Current and Noncurrent Assets / Liabilities
|--- | -------------------------------------------------------------



| | A. | Assets that meet one of the following criteria are classified as current assets; otherwise they are classified as noncurrent assets:
| | -- | ------------------------------------------------------------------------------------------------------------------------------------



| | (a) | Assets arising from operating activities that are expected to be realized or consumed, or are intended to be sold within the normal operation cycle;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Assets held mainly for trading purposes;
| | --- | ----------------------------------------



| | (c) | Assets expected to be realized within twelve months from the balance sheet date;
| | --- | --------------------------------------------------------------------------------



| | (d) | Cash or cash equivalents, excluding restricted cash and cash equivalents and those that are to be exchanged or used to pay off liabilities more than twelve months after the balance sheet date.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | Liabilities that meet one of the following criteria are classified as current liabilities; otherwise they are classified as noncurrent liabilities:
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | Liabilities arising from operating activities that are expected to be paid off within the normal operating cycle;
| | --- | -----------------------------------------------------------------------------------------------------------------



| | (b) | Liabilities arising mainly from trading activities;
| | --- | ---------------------------------------------------



| | (c) | Liabilities that are to be paid off within twelve months from the balance sheet date;
| | --- | -------------------------------------------------------------------------------------



| | (d) | Liabilities for which the repayment date cannot be extended unconditionally to more than twelve months after the balance sheet date.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------



|(7) | Cash and Cash Equivalents
|--- | -------------------------

Cash and cash equivalents includes cash on hand, deposits
held at call with banks, time deposits that meet operating short-term cash commitments, and other short-term highly liquid investments.



|(8) | Accounts Receivable
|--- | -------------------

Accounts receivable is recognized initially at fair value and
subsequently measured at amortized cost using the effective interest method, less provision for impairment. Accounts receivable expected to be collected over one year is recorded at present value by using predetermined interest rate whereas those
expected to be collected within one year are not reported at present value due to the fact that the difference between the maturity value and the fair value discounted by implicit interest rate is immaterial and the frequency of transactions is
high.



|(9) | Inventories
|--- | -----------

Inventories are recorded at cost when acquired under a perpetual inventory
system. Cost is determined using the weighted-average method. The cost of finished goods and work in process comprises raw materials, direct labor, other direct costs and related production overheads based on normal operating capacity. As of the
balance sheet date, inventories are stated at the lower of cost or net realizable value by item, except where it may be appropriate to similar groups or related items. Net realizable value is the estimated selling price in the ordinary course of
business less all estimated costs of completion and necessary selling expenses.

|(10) | Financial Assets
|---- | ----------------



| | A. | Classification
| | -- | --------------

The Group classifies its financial assets in the following categories: at fair
value through profit or loss, loans and receivables, available-for-sale, and held-to-maturity. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets
at initial recognition.



| | (a) | Loans and receivables
| | --- | ---------------------

Loans and receivables are non-derivative financial assets with fixed or
determinable payments that are not quoted in an active market.



| | (b) | Available-for-sale financial assets
| | --- | -----------------------------------

Available-for-sale financial assets are non-derivative
financial assets that are either designated in this category or not classified in any of the other categories.



| | B. | Recognition and Measurement
| | -- | ---------------------------



| | (a) | Regular purchases and sales of financial assets are recognized on the trade date (the date on which the Company commits to purchase or sell the asset).
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------

Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in
the income statement. Other financial assets not carried at fair value through profit or loss are initially recognized at fair value plus transaction costs. Financial assets are derecognized when the rights to receive cash flows from the investments
have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership.



| | (b) | Financial assets at fair value through profit or loss and available-for-sale financial assets are subsequently carried at fair value. Gains or losses arising from changes in the fair value of the financial assets
at fair value through profit or loss category are presented in the income statement within other gains and losses in the period in which they arise. Changes in the fair value of securities classified as available-for-sale are
recognized in other comprehensive income. Dividend income from these two assets is recognized in the income statement as part of other income when the Groups right to receive payments is established.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Loans and receivables and held-to-maturity investments are subsequently carried at amortized cost using the effective interest method. The interest arising subsequently is recognized in other income in the
income statement.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | When securities classified as available-for-sale are sold or impaired, the accumulated fair value adjustments recognized in equity are included in the income statement as gains and losses from investment
securities.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(11) | Impairment of Financial Assets
|---- | ------------------------------



| | A. | Assets carried at amortized cost
| | -- | --------------------------------



| | (a) | The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or group of financial assets is impaired. A financial asset or a group of financial asset is impaired and
impairment losses are incurred only if:
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | i. | There is objective evidence of impairment as a result of one or more events that occurred after initial recognition of the asset (a loss event), and
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii. | That loss event has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------

Evidences of impairment include:



| | i. | The debtor or the issuer is experiencing significant financial difficulty;
| | -- | --------------------------------------------------------------------------



| | ii. | Default or delinquency in interest or principal payment;
| | --- | --------------------------------------------------------



| | iii. | The probability that the debtor or debtors will enter bankruptcy or other financial reorganisation; and
| | ---- | -------------------------------------------------------------------------------------------------------



| | iv. | Where observable data indicates that there is a measurable decrease in the estimated future cash flow, such as:
| | --- | ---------------------------------------------------------------------------------------------------------------



| |  |  | The repayment condition of the debtor to the Group of assets deteriorated
| | - |  | -------------------------------------------------------------------------



| |  |  | Changes in areas or economic conditions that correlate with defaults
| | - |  | --------------------------------------------------------------------



| | (b) | For these assets, the amount of the loss is measured as the difference between the assets carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been
incurred) discounted at the financial assets original effective interest rate. The carrying amount of the asset is reduced through the allowance account and the amount of the loss is recognized in the consolidated income statement. In a
subsequent period, if the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtors credit rating), the reversal of the
previously recognized impairment loss is recognized in the consolidated income statement.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | Available-for-sale assets
| | -- | -------------------------

The Company assesses at the end of each reporting period whether
there is objective evidence that a financial asset or a group of financial assets is impaired. In the case of equity investments classified as available-for-sale, any significant unfavorable change that takes place in the technical, market,
economic, or legal environments where the issuer operates indicates the possibility that the investment cost of the equity instrument may not be recovered and a significant or prolonged decline in the fair value of the security below its cost are
evidences that the assets are impaired. If any such evidence exists for available-for-sale financial assets, the cumulative loss - measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that
financial asset previously recognized in profit or loss  is removed from equity and recognized in profit or loss. Impairment losses recognized in the consolidated income statement on equity instruments are not reversed through the consolidated
income statement.



|(12) | Equity Method Investments (Investments in associate and joint arrangements)
|---- | ---------------------------------------------------------------------------

Investment in associate



| | A. | Associates, which are accounted for using the equity method of accounting, are all entities over which the Company has significant influence, which means the power to participate in the financial and operating policy
decisions of the investees, but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under the equity method, the investment is initially recognized at cost, and the carrying amount is increased or decreased to recognize the
investors share of the profit or loss of the investee after the date of acquisition. The Companys investment in associates includes goodwill identified on acquisition.



| | B. | The Companys share of post-acquisition profit or loss is recognized in the income statement, and its share of post-acquisition movements in other comprehensive income is recognized in other comprehensive income
with a corresponding adjustment to the carrying amount of the investment. When the Companys share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Company does not
recognize further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in other comprehensive income is reclassified to profit or loss
where appropriate. Dilution gains and losses arising in investments in associates are recognized in the income statement.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Investment in joint arrangements



| | A. | Investments in joint arrangement are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor. A joint venture is a joint arrangement whereby the
parties that have joint control of the arrangement have rights to the net assets of the arrangement. The Company has assessed the nature of its joint arrangement and determined it to be a joint venture which is accounted for using the equity method.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | Under the equity method of accounting, interests in joint ventures are initially recognized at cost and adjusted thereafter to recognize the Companys share of the post-acquisition profits or losses and movements
in other comprehensive income. When the Companys share of losses in a joint venture equals or exceeds its interests in the joint ventures, the Company does not recognize further losses, unless it has incurred obligation or made payments on
behalf of the joint ventures.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Other significant policies of the equity method

Profits and losses resulting from upstream and downstream transactions between the Company and its associates or joint ventures are recognized
in the Companys financial statements only to the extent of unrelated investors interests in the associates or joint ventures. Unrealized losses are eliminated unless the transaction provides evidence of an impairment of the asset
transferred. Material accounting standard differences between associates or joint ventures and the Group were properly assessed and recorded.

The Company determines at each reporting date whether there is any objective evidence that the investment in the associate or joint venture is
impaired. If this is the case, the Company calculates the amount of impairment as the difference between the recoverable amount of the associate or joint venture and its carrying value and recognizes the amount in other gains and losses
in the income statement.



|(13) | Property, Plant and Equipment
|---- | -----------------------------



| | A. | Property, plant and equipment are stated at historical cost less depreciation. The acquisition costs include the purchase price, any costs directly attributable to bringing the asset to the location and condition
necessary for it to be capable of operating, and the obligations to dismantle and remove the items and restore the site on which they are located. The subsequent costs will only be recognized under the conditions that future economic benefits
associated with the item will flow to the Group and the item cost can be measured reliably. The carrying amount of the replaced part is derecognized. Day-to-day servicing costs and repairment expenditures are recognized as expenses as incurred.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | The Group capitalizes borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. The capitalized borrowing costs will be
depreciated through the residual useful lives of related items. Borrowing costs which do not qualify for capitalization are recognized in profit or loss.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | If a material part of replacing items of property, plant and equipment has different useful life from the main asset, it should be recognized and depreciated separately. Land is not depreciated. Depreciation on other
assets is calculated using the straight-line method to allocate their cost to their residual values over their estimated useful lives. The useful lives of fixed assets are 5 to 15 years, except for buildings, which are 20 to 55 years.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The assets residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each fiscal year.



| | D. | Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized within Other gains or losses in the income statement.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(14) | Intangible Assets
|---- | -----------------

Intangible assets are the expenditures of license fees and computer
software. License fees are capitalized at historical cost. Acquired computer software is capitalized on the basis of the costs incurred to acquire and bring to use the specific software. Both license fees and computer software are intangible assets
with limited useful lives. They are subsequently measured at cost less accumulated amortization and impairment. Computer software is amortized over three years whereas license fees are amortized over their economic lives or the contract years using
straight-line method.

|(15) | Impairment of Non-financial Assets
|---- | ----------------------------------



| | A. | Assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment. Assets that are subject to amortization are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the assets carrying amount exceeds its recoverable amount. For the purposes of assessing impairment, assets are
grouped at the lowest levels for which there are largely independent cash flows (cash-generating units). The recoverable amount is the higher of an assets fair value, defined as the price that would be received to sell an asset or paid to
transfer a liability in an orderly transaction between market participants at the measurement date, less costs to sell and value in use. The value in use is the present value of the future cash flows expected to be derived from an asset or
cash-generating unit.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | An impairment loss recognized in prior periods for an asset other than goodwill shall be reversed if there has been a change in the estimates used to determine the assets recoverable amount since the last
impairment loss was recognized. The carrying amount of the asset shall be reversed to its recoverable amount. The increased carrying amount of an asset attributable to a reversal of an impairment loss shall not exceed the carrying amount that would
have been determined had no impairment loss been recognized for the asset in prior years.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(16) | Accounts Payable
|---- | ----------------

Accounts payable are obligations to pay for goods or services that
have been acquired in the ordinary course of business from suppliers. Accounts payable are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method. Accounts payable of which payment due is
within one year or less are not discounted while their fair value are close to the value in maturity and they are transacted actively.



|(17) | Derecognition of Financial Liabilities
|---- | --------------------------------------

The Group shall remove a financial liability
from its balance sheet when the obligation specified in the contract is discharged or cancelled or expired.



|(18) | Borrowings
|---- | ----------

Borrowings are recognized initially at fair value, net of transaction costs
incurred, and subsequently carried at amortized cost. Any difference between the proceeds, net of transaction costs, and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest
method. Fees paid on the establishment of loan facilities are recognized as transaction costs of the loan to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw-down
occurs. To the extent there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is capitalized as a prepayment for liquidity services and amortized over the period of the facility to which it relates.



|(19) | Income Tax
|---- | ----------



| | A. | The tax expense for the period comprises current and deferred tax. Tax is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity.
In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | B. | The current income tax is calculated on the basis of the tax law enacted or substantively enacted at the balance sheet date in the countries where the Group operates and generates taxable income. Management periodically
evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

| | C. | Additional 10% undistributed earnings tax is estimated and recognized during the period when income is earned.
| | -- | --------------------------------------------------------------------------------------------------------------



| | D. | Deferred income tax is recognized, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements.
However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill; deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a
business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates that have been enacted or substantively enacted by the balance sheet date and are
expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled. Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available
against which the temporary differences can be utilized.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | E. | Except for deferred income tax liability where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the forseeable
future, deferred income tax is provided on temporary differences arising on investments in subsidiaries, associates, and joint arrangements. Deferred income tax assets are recognised on deductible temporary differences arising from investments in
subsidiaries, associates and joint arrangements only to the extent that it is probable the temporary difference will reverse in the future and there is sufficient taxable profit available against which the temporary difference can be utilised.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | F. | Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income taxes assets and liabilities
relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balance on a net basis.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | G. | Deferred income tax assets are recognized on deductible temporary differences only to the extent that there is sufficient taxable profit available against which the temporary difference can be utilized. The investment
tax credits relating to the acquisition cost of qualifying equipment or technology, qualifying research and development expenditure, qualifying personnel training expenditure and qualifying investments in significant technology companies are
recognized as income tax adjustments in the period the tax credits arise.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(20) | Employee Benefits
|---- | -----------------



| | A. | Short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in respect of service rendered by employees in a period and should be recognized as expenses in that period when
the employees render service.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | For defined contribution plans, the Group pays contributions to a publicly or privately administered pension fund. The contributions are recognized as employee benefit expenses when they are due. The Group has no legal
or constructive obligations to pay further contributions if the fund does not hold sufficient assets to pay all employees the benefits.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | For defined benefit plan, the liability recognized in the balance sheet is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit
obligation is calculated annually by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of government
bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating to the terms of the related pension obligation.

| | D. | Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise. Past-service costs
are recognized immediately in income.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | E. | For employees bonuses and directors and supervisors remunerations, the Company recognizes cost/expense and related liability when the Company has legal obligation and could reasonably estimate such
amount. Any difference between estimated amount and distributed amount resolved in the stockholders meeting in the subsequent year shall be adjusted in the income/loss of the following year.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(21) | Provision
|---- | ---------



| | A. | Provisions are recognized when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount
has been reliably estimated. Provisions are not recognized for future operating losses.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks
specific to the obligation. The increase in the provision due to passage of time is recognized as interest expense.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | A contingent liability is a possible obligation that arises from past events and whose existence will be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not wholly within the
control of the entity. A present obligation that arises from past events but is not recognized because either that it is not probable that an outflow of resources embodying economic benefits will be required to settle the obligation or that the
amount of the obligation cannot be measured with sufficient reliability.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(22) | Revenue Recognition
|---- | -------------------

The Group provides assembly, testing, and turnkey services for
integrated circuits. The Company recognizes revenue when:

A. the amount of revenue can be measured reliably;

B. it is probable that the economic benefits associated with the transaction will flow to the entity;

C. the stage of completion of the transaction at the end of the reporting period can be measured reliably;

D. the costs incurred for the transaction and the cost to complete the transaction can be measured reliably.

The revenue amount to be recognized is based on the agreed price by both parties of the transaction and the stage of completion. The allowance
is estimated by historical experiences and recorded as a deduction to the revenue.



|(23) | Lease
|---- | -----

Leases in which a significant portion of the risks and rewards of ownership are
retained by the lessor are classified as operating leases. Payments made under operating leases (net of incentives received from the lessor) are charged to the income statement on a straight-line basis over the period of the lease.



|(24) | Treasury Stock
|---- | --------------

Where any Group company purchases the Companys equity share
capital (treasury stock), the consideration paid, including any directly attributable incremental costs (net of income taxes) is deducted from equity attributable to the Companys equity holders until the shares are cancelled or reissued. Where
such ordinary shares are subsequently reissued, any consideration received, net of any directly attributable incremental transaction costs and the related income tax effects, is included in equity attributable to the Companys equity holders.

|(25) | Share-based Compensation
|---- | ------------------------

The Company operates an equity-settled, share-based
compensation plan under which the Company receives services from employees as consideration for equity instruments of the Company. The fair value of the employee services received in exchange for the grant of the shares is recognized as an expense
during the vesting period. The total amount to be expensed is determined by reference to the fair value of the shares granted.



|5. | Critical Accounting Estimates and Judgments
|-- | -------------------------------------------

The Group makes estimates and assumptions
concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and
liabilities within the next financial year are addressed below.



| | (1) | Deferred Income Tax
| | --- | -------------------

By using the liability method, the Company recognizes future
deferred tax assets and deferred tax liabilities, which are incurred from temporary differences and investment credits. While assessing the reliability of deferred tax assets, management exercises material accounting judgments and estimates,
including assumptions related to projected growth of future revenues, profitability, tax-free period, usage of tax credits, and tax planning. Any environmental movements of global economic and industry, and regulations changes will impact the amount
of current income tax expense and the net value of deferred tax assets. For more illustrations, please refer to Note 25.



| | (2) | Fair Value of Financial Assets
| | --- | ------------------------------

The fair value of financial instruments that are not
traded in an active market (for example, over-the counter equity investment) is determined by using valuation techniques. The Company uses its professional judgment to select a variety of methods and make assumptions that are mainly based on market
conditions existing at the end of each reporting period. For valuing these assets, the Company maximizes the use of observable market data where it is available and rely as little as possible on entity specific estimates. For more illustration of
related sensitivity analysis, please refer to Note 33.



| | (3) | Pension Benefits
| | --- | ----------------

The present value of the pension obligations depends on a number of
factors that are determined on an actuarial basis using a number of assumptions. The assumptions used in determining the net cost (income) for pensions include the discount rate. Any changes in these assumptions will impact the carrying amount of
pension obligations. Other key assumptions for pension obligations are based in part on current market conditions. Additional information is disclosed in Note 16.

| | A. | The Company acquired common shares of AcSiP Technology Corp. (AcSiP) to upgrade assembly related technology. Although the Company holds less than 20% of the equity shares of AcSiP, the Company exercises significant
influence by appointing one director of the Board of Directors in AcSiP, thus maintains the evaluation of equity method. As a result of the increase of AcSiPs issued shares, which were not purchased or obtained proportionally by the Company,
equity investments and gain on disposal of investments of $19,562 and ($4,330) were adjusted for the years ended December 31, 2012 and 2013, respectively. In addition, the Company disposed 158 thousand and 100 thousand shares and
recognized gain on disposal of investments of $17,113 and $641 for the years ended December 31, 2012 and 2013, respectively. In June 2012 and June 2013, the investee distributed cash dividends which could be deemed as return of investment cost
under the equity method, and the Company decreased equity investments of $5,250 and $12,259. As of December 31, 2013, the ownership over the investee increased due to the common stock buy-back plan performed by AcSiP. The Company accounted for
such an ownership change as additional acquisition.

The book values of the items above are the same as their fair values, classified in Level 2 by using market
approach. The fair values of equity investments are classified in Level 1 or Level 2 depending on the observability of the significant inputs. Long-term loans are floating interest rates; as a result, the Company expected that there is no material
difference between the carrying value and the fair value (Level 2).

16. Post-employment Benefit



| | A. | Defined Benefit Plan
| | -- | --------------------

In accordance with the Labor Standards Act, the Company has a
funded defined benefit pension plan covering all eligible employees prior to the enforcement of the Labor Pension Act (the Act), effective on July 1, 2005, and employees choosing to continue to be subject to the pension mechanism
under the Labor Standards Law after the enforcement of the Act. Pension benefits are generally based on service years and six-month average wages and salaries before retirement of the employee. Two units are earned per year for the first 15 years of
service and one unit is earned for each additional year of service with a maximum of 45 units. Under the funding policy of the plan, the Company contributes monthly an amount equal to 2% of the employees monthly salaries and wages to the
pension fund, which is the custodian for labor pension, deposited with the Bank of Taiwan.

On March 20, 2014, the Companys Board of Directors also proposed to distribute employees
bonuses of $623,272 and directors and supervisors remuneration of $55,477, all paid in cash. The aforementioned earnings distribution resolution has not been passed by the shareholder resolution. Any information in relation to the
Companys Board of Directors proposals and shareholders resolution on earnings distribution will be posted in the Market Observation Post System on the website of the Taiwan Stock Exchanges.



| | H. | Since the 2014 shareholders meeting has yet to be held, there is uncertainty about the earnings distribution. This is to say, the potential tax influence of the additional 10% tax on undistributed earnings cannot
be reasonably estimated yet.

(EXPRESSED IN THOUSANDS OF NEW TAIWAN DOLLARS, EXCEPT EARNINGS PER SHARE)



| | (3) | Interest rate risk
| | --- | ------------------

The Groups interest rate risk arises from cash, cash equivalent, and
borrowings. Mostly, residual cash will be held as deposit. As of January 1, 2012, December 31, 2012 and December 31, 2013, the Group withheld financial assets with cash flow interest rate risk of $3,737,200, $162,257 and $132,531
and financial liabilities with cash flow interest rate risk of $9,548,750, $15,227,000, and $18,539,583. If the interest rate had been increased/decreased by 10 points, income before income tax for the period would have been $5,812, $15,065, and
$18,407 higher/lower.



| | B. | Credit risk
| | -- | -----------

The Groups credit risk mainly arises from cash and cash equivalents
(deposits with banks or financial institutions), accounts and notes receivable and refundable deposits.



| | (1) | For risks from banks and financial institutions, The Group periodically assesses their credit with information provided by external independent rating institutes. Furthermore, to minimize the credit risk, The Group
allocates deposits in accordance with each banks rating, from high to low. After the assessment, most of our correspondent banks and financial institutions are with minimum rating of A, which represents low possibility of
occurrence of credit default.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | For risks from accounts and notes receivable, The Group assesses customers credit quality through internal risk assessment, taking into account their current financial conditions and past experiences. After the
assessment, management does not expect any losses from non-performance by these counterparties.

34. Capital Risk Management

The capital includes common share, paid-in capital, legal reserve, and other comprehensive income. The Groups objectives when managing
capital are to safeguard the Groups ability to continue as a going concern in order to provide returns for shareholders and to maintain an optimal capital structure to reduce the cost of capital.

In order to maintain or adjust the capital structure by using adequate manner, the Group keeps reviewing change of internal capital structure
and other competitors ratios. The Group monitors the capital on the basis of external limits, including Current ratio, Liability to Equity ratio, and Interest Protection Multiples (earnings before interest, taxes, depreciation, and
amortization), as follows:



| | A. | Current ratio: Current assets divide by current liabilities
| | -- | -----------------------------------------------------------



| | B. | Liability to Equity ratio: Total liabilities plus externally guaranteed amounts divide by shareholders equities
| | -- | ----------------------------------------------------------------------------------------------------------------



| | C. | Interest Protection Multiples: Earnings before income taxes plus interest expenses plus depreciation and amortization expenses divide by interest expenses
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------

| | (1) | The fair value of financial instruments traded in active markets is based on quoted market price at the balance sheet date. For financial instruments with fair value not traded in active markets, the Company uses
valuation techniques, which maximizes the use of observable market data where it is available and relies as little as possible on entity specific estimates. The valuation technique currently used is the market approach. The valuation is based on the
benchmark companies stock prices and other specific indexes. If the investees are investment companies, the Company uses their net equities as fair value because their net equities are measured at fair value.

37. Transition to IFRS in 2012

As discussed in Note 4, these are the Groups first financial statements prepared in accordance with IFRS. The accounting policies set out
in Note 4 have been applied in preparing the consolidated financial statements for the year ended December 31, 2013, the comparative information presented in these financial statements for the year ended December 31, 2012 and in the
preparation of an opening IFRS consolidated balance sheet on January 1, 2012 (the Groups transition date to IFRS).

The Group
has complied with the exception rule under IFRS 1 not to retrospectively apply the aspect of estimates. As of the transition date, the estimates made by the Group under IFRS are in accordance with the estimates previously made under
R.O.C. GAAP after the adjustments to reflect GAAP differences.

Material differences identified by the Group arising from differences
between previous accounting policies, R.O.C. General Accepted Accounting Principles, and IFRS, and the effects of exemptions elected by the Group under IFRS 1, First-time Adoption of International Financial Reporting Standards, are set
forth as:

| | D. | Reconciliation of statement of cash flows as previously reported under R.O.C. GAAP to IFRS in 2012:
| | -- | ---------------------------------------------------------------------------------------------------

By using the indirect method, the Group prepared its statement of cash flows in accordance with R.O.C. GAAP and was not required to disclose
the amounts of paid interest, received interest, and paid tax. However, pursuant to IAS No. 17, Statement of Cash Flows, the Group disclosed received interest of $117,234, paid interest of $181,154, and paid tax of $615,855,
respectively. The Group also classified received interest, paid interest, and paid tax to the category, from operating activities, and classified payment for cash dividends to the category, financing activities, by their
nature.

Moreover, the definition of cash in accordance with IAS No. 7, Statement of Cash Flows, comprises cash on hand,
demand deposits, and the short-term, highly liquid investments that are readily convertible to known amounts.

Except for the differences
above, there is no material difference within the statements of cash flows prepared under R.O.C. GAAP and IFRS.



| | E. | Reasons for differences are outlined below:
| | -- | -------------------------------------------



| | (1) | Income tax:
| | --- | -----------

In accordance with R.O.C. GAAP, a deferred tax asset can be offset by another
deferred tax liability for the income taxes levied by the same taxation authority. However, pursuant to IAS No. 12, Income Taxes, the entity can offset deferred tax assets and deferred tax liabilities if, and only if, the entity has
a legally enforceable right to set off current tax assets against current tax liabilities. As of January 1, 2012 and December 31, 2012, the Group reclassified partial deferred tax assets of $15,711 and $76,182 to deferred tax liabilities.

(EXPRESSED IN THOUSANDS OF NEW TAIWAN DOLLARS, EXCEPT EARNINGS PER SHARE)



Furthermore, under R.O.C. GAAP, a deferred tax asset or liability should, according to the
classification of its related asset or liability, be classified as current or noncurrent. However, pursuant to IFRS, a deferred tax asset or liability should be classified as non-current, and therefore, the reclassified amounts were $307,496 and
$338,463 as of January 1, 2012 and December 31, 2012, respectively.

Pursuant to the regulation in R.O.C., a 10% tax on
undistributed earnings is recognized as a tax expense in the year of stockholders approval, but, under Full IFRS, it should be accrued during the period the earnings generated and adjusted to the extent that distributions are approved by the
stockholders in the following year. The Group recognized adjustment to the retained earnings of ($435,352) as of January 1, 2012, and a tax expense of $45,952 for the year ended December 31, 2012.



| | (2) | Financial assets:
| | --- | -----------------

In accordance with R.O.C. GAAP, unlisted stocks and emerging stocks held by
the Company should be measured at cost and recognized as Financial assets carried at cost. However, pursuant to IAS 39, Financial Instruments  Recognition and Measurement, investments in equity instruments without an
active market but with reliable fair value measurement (i.e. the variability of the estimation interval of reasonable fair values of such equity instruments is insignificant, or the probability for these estimates can be made reliably) should be
measured at fair value. As of January 1, 2012 and December 31, 2012, by electing the exemption of IFRS 1, the Company designated the investments previously classified as Financial assets carried at cost as
Available-for-sale financial assets of $1,932,643 and $1,932,643, and recognized fair value adjustment for Available-for-sale financial assets of $186,322 and $351,007 and Unrealized gain on available-for-sale financial
assets of $175,899 and $319,854 under shareholders equity.

As of January 1, 2012, the Company recognized an adjustment
between fair value and carrying amount to decrease retained earnings of $6,857, due to a decline in fair value of the asset.



| | (3) | Prepayments for equipment:
| | --- | --------------------------

For prepayments made for property, plant and equipment, in
accordance with the requirements under IFRS, the Group reclassified the prepayments to other noncurrent assets of $0 and $6,815 as of January 1, 2012 and December 31, 2012.



| | (4) | Employee benefits
| | --- | -----------------

Previously, the Company valued defined benefit obligations and recognized
related pension costs and accrued pension liabilities under R.O.C. GAAP. Pursuant to IAS 19, Employee Benefits, the Company identified several differences as follows:



| | i. | The discount rate used to calculate pensions shall be determined with reference to the factors specified in R.O.C. SFAS 18, paragraph 23. However, IAS 19, Employee Benefits, requires an entity to determine
the rate used to discount employee benefits with reference to market yields at the end of the reporting period on high quality corporate bonds of a currency and term consistent with the currency and term of the benefit obligation; when there is no
deep market in corporate bonds, an entity is required to use market yields on government bonds (at the end of the reporting period) instead.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii. | In accordance with the Groups accounting policies, unrecognized prior service costs should be amortized on a straight-line basis over the average remaining service period of employees still in service and expected
to receive benefits. However, the prior service costs in IAS 19 are not applied to the Group as the first-time adopter of IFRS, so the Group has no unrecognized prior service costs.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iii. | In accordance with R.O.C. GAAP, the excess of the accumulated benefit obligation over the fair value of the pension plan (fund) assets at the balance sheet date is the minimum amount of pension liability that is
required to be recognized on the balance sheet (minimum pension liability). However, IAS 19, Employee Benefits, has no regulation regarding the minimum pension liability.
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iv. | In accordance with R.O.C. GAAP, actuarial pension gain or loss of the Company is recognized in net pension cost of current period using the corridor method. However, in accordance with IAS 19,
Employee Benefits, the Company recognizes immediately actuarial pension gain or loss in other comprehensive income.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

After the valuation, the Company recognized accrued pension liabilities of $972,184 and
$992,340, with actuarial loss $14,306 in other comprehensive income, and reversed the minimum pension liabilities of $390,516 and $372,945 as of January 1, 2012 and December 31, 2012. As a result, the equity adjustments increased $377,304
and $360,783, respectively. In addition, the Company reversed the pension costs recognized under R.O.C. GAAP and recognized pension costs according to IAS 19, Employee Benefits. The adjustments decreased other liabilities of $39,145,
operating costs of $27,249, and expenses of $11,896 for the year ended December 31, 2012.

Last, R.O.C. GAAP does not have any
specified rules for recognition of accumulated unused compensated absences. The Company recognized such costs as salary expense upon actual payment. However, IAS 19, Employee Benefit, requires that the costs of accumulative compensated
absences be accrued as expenses at the end of the reporting period. As of January 1, 2012 and December 31, 2012, the Company increased other payables of $161,262 and $246,253, and decreased retained earnings of $134,843 and of $205,414.



| | (5) | Cumulative translation differences:
| | --- | -----------------------------------

The Company has elected to reset the cumulative
translation differences arising on the translation of the financial statements of foreign entities under R.O.C. GAAP to zero at January 1, 2012, and increased retained earnings of $375,051 consequently. Total equity does not change due to this
adjustment.

In accordance with R.O.C. GAAP, the functional currency of the subsidiaries performing investing activities is determined as
U.S. Dollars. However, under IFRS, the functional currency of those subsidiaries was determined to be New Taiwan Dollars and their financial results have been remeasured as of the transition date. All the transition impacts have been recorded in the
opening accounts. The remeasurement difference of 2012 of $461 was adjusted in Income Statements of 2012.



| | (6) | Presentation of financial statements:
| | --- | -------------------------------------

The Company has reclassified certain accounts to
conform with the requirements under IFRS. Time deposit with original maturity over one year is reclassified from cash and cash equivalents to other receivables; deferred expenses are reclassified to intangible assets and other assets according to
their substances; leasing assets and idle assets previously under other assets is reclassified to plant, property, and equipments, and their depreciation expenses is reclassified from other losses to operating expenses.



| | (7) | Adjustments to Reflect the Investors Ownership Change in its Investees
| | --- | -----------------------------------------------------------------------

The adjustments
to reflect the Companys ownership change in its equity-method investees are recognized in paid in capital under R.O.C. GAAP, while they are perceived as deemed disposal of the investments and booked as gains or losses under IFRS. The Company
recognized gains on disposal of investments of $19,562 for the year ended December 31, 2012.



| | F. | Exemptions elected:
| | -- | -------------------

Expect for the exemptions elected above, the Group also elects the
exemptions below:



| | (1) | Business combination:
| | --- | ---------------------

The Group elected not to retrospectively adopt the rule of IFRS 3,
Business Combinations for the transactions occurred before the IFRS transition date.
