Risk Factors

Risks Relating to Economic Conditions and the Financial Markets

The global credit
and financial markets crisis could materially and adversely affect our business and results of operations.

Disruptions in global credit and financial markets may occur that cause diminished liquidity and limited availability of credit, reduced
consumer confidence, reduced economic growth, increased unemployment rates and uncertainty about economic stability. Limited availability of credit in financial markets may lead consumers and businesses to postpone spending. This in turn may cause
our customers to cancel, decrease or delay their existing and future orders with us. Financial difficulties experienced by our customers or suppliers as a result of these conditions could lead to production delays and delays or defaults in payment
of accounts receivable. Continuing credit markets disruption restricts our access to capital and limits our ability to fund operations or to refinance maturing obligations as they become due through additional borrowing or other sources of
financing. We are not able to predict the duration or extent of disruptions in global credit and financial markets that occurred in and since 2009 and through 2014. These conditions increase the difficulty of accurately forecasting and planning our
business activities. If these conditions and uncertainties continue or if credit and financial markets and confidence in economic conditions further deteriorate, our business and results of operations could be materially and adversely affected.

Risks Relating to Our Industry

Because we depend on the highly cyclical semiconductor industry, which is characterized by significant and sometimes prolonged downturns from time to time, our revenue and earnings may fluctuate
significantly, which in turn could cause the market price of our common shares to decline.

Because our business is,
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. All of our customers operate in this industry and variations in order levels from our customers and in service fee rates may result in volatility in our revenue and earnings. For instance, during periods of decreased demand
for assembled semiconductors, some of our customers may even simplify, delay or forego final testing of certain types of semiconductors, such as dynamic random access memory or DRAM, further intensifying our difficulties. From time to time, the
semiconductor industry has experienced significant, and sometimes prolonged, downturns which have adversely affected our results of operations. In 2009, the semiconductor industry, especially the assembly and testing services for DRAM products
sector, continued to experience the significant downturn that began in fourth quarter of 2008, and which has adversely affected our business. This industry downturn started to recover from the second quarter of 2009, and our revenue for 2010
increased 42% from 2009 levels. Our revenue for 2011 increased 6% from 2010 levels. Our revenue for 2012 increased 6% from 2011 levels. Our revenue for 2013 increased 0.7 % from 2012 levels. Our revenue for 2014 increased 13.7 % from 2013
levels and generated a profit of NT$1,663 million (US$53 million) in 2014. We cannot give any assurances that there will not be any downturn in the future or that any future downturn will not affect our results of operations.

Any deterioration in the market for end-user applications for semiconductor products would reduce demand for our services and may result in a
decrease in our earnings.

Market conditions in the semiconductor industry track, to a large degree, those for their
end-user applications. Any deterioration in the market conditions for the end-user applications of semiconductors we test and assemble could reduce demand for our services and, in turn, materially adversely affect our financial condition and results
of operations. Our revenue is largely attributable to fees derived from testing and assembling semiconductors for use in personal computers, communications equipment, consumer electronic products and display applications. A significant decrease in
demand for products in these markets could put pricing pressure on our testing and assembly services and negatively affect our revenue and earnings. Weak demand for LCD and other flat-panel display products began in 2007 and has since adversely
affected our operating results in 2008, 2009, and 2010. The LCD driver market started to recover in the second quarter of 2009 and the positive recovery trend continued through 2014. We cannot give any assurances that there will not be any downturn
in the future or that any future downturn will not affect our results of operations. Any significant decrease in demand for end-user applications of semiconductors will negatively affect our revenue and earnings.

A decline in average selling prices for our services could result in a decrease in our earnings.

Historically, prices for our testing and assembly services in relation to any given semiconductor tend to decline over the course of its
product and technology life cycle. See also A decrease in market demand for LCD and other flat-panel display driver semiconductors may adversely affect our capacity utilization rates and thereby negatively affect our profitability.
If we cannot reduce the cost of our testing and assembly services, or introduce higher-margin testing and assembly services for new package types, to offset the decrease in average selling prices for our services, our earnings could decrease.

A reversal or slowdown in the outsourcing trend for semiconductor testing and assembly services could
reduce our profitability.

In recent years, integrated device manufacturers, or IDMs, have increasingly outsourced
stages of the semiconductor production process, including testing and assembly, to independent companies like us to shorten production cycles. In addition, the availability of advanced independent semiconductor manufacturing services has also
enabled the growth of so-called fabless semiconductor companies that focus exclusively on design and marketing and outsource their manufacturing, testing and assembly requirements to independent companies. A substantial portion of our
revenue is indirectly generated from providing semiconductor assembly and testing services to these IDMs and fabless companies. We cannot assure you that these companies will continue to outsource their testing and assembly requirements to
independent companies like us. A reversal of, or a slowdown in, this outsourcing trend could result in reduced demand for our services, which in turn could reduce our profitability.

Risks Relating to Our Business

If we are unable to compete effectively in the highly
competitive semiconductor testing and assembly markets, we may lose customers and our income may decline.

The
semiconductor testing and assembly markets are very competitive. We face competition from a number of IDMs with in-house testing and assembly capabilities and other independent semiconductor testing and assembly companies. Our competitors may have
access to more advanced technologies and greater financial and other resources than we do. Many of our competitors have shown a willingness to reduce prices quickly and sharply in the past to maintain capacity utilization in their facilities during
periods of reduced demand. In addition, an increasing number of our competitors conduct their operations in lower cost centers in Asia such as Mainland China, Thailand, Vietnam and the Philippines. Any renewed or continued erosion in the prices or
demand for our testing and assembly services as a result of increased competition could adversely affect our profits.

We are highly
dependent on the market for memory products. A downturn in market prices for these products could significantly reduce our revenue and profit.

A significant portion of our revenue is derived from testing and assembling memory semiconductors. Our revenue derived from the testing and assembly of memory semiconductors accounted for 50% and 52% of
our revenue in 2013 and 2014, respectively. In the past, our service fees for testing and assembling memory semiconductors were sharply reduced in tandem with the decrease in the average selling price of DRAM in the semiconductor industry. The
continuing oversupply of DRAM products in 2008 and the weak demand in the DRAM market in the period from 2009 to 2013 resulted in significant reductions in the price of DRAM products, which in turn drove down the average prices for our testing and
assembly services for DRAM products in these periods. We cannot assure you that there will not be further downturns in DRAM prices in the future.

A decrease in market demand for LCD and other flat-panel display driver semiconductors may adversely affect our capacity utilization rates and thereby negatively affect our profitability.

Our testing and assembly services for LCD and other flat-panel display driver semiconductors generated revenue of
NT$4,781 million and NT$5,171 million (US$164 million) in 2013 and 2014, respectively. We invested NT$2,054 million and NT$1,056 million (US$33 million) in 2013 and 2014, respectively, on equipment for tape carrier package, or TCP, chip-on-film, or
COF and chip-on-glass, or COG, technologies, which are used in testing and assembly services for LCD and other flat-panel display driver semiconductors. Most of this equipment may not be used for technologies other than TCP, COF or COG. The market
demand for LCD and other flat-panel display driver semiconductors and related testing and assembly services increased in 2013 and 2014 compared to the market demand in 2012. Any significant decrease in demand for these products and our related
services, however, would significantly impair our capacity utilization rates. That may result in our inability to generate sufficient revenue to cover the significant depreciation expenses for the equipment used in testing and assembling LCD and
other flat-panel display driver semiconductors, thereby negatively affecting our profitability. See also Because of our high fixed costs, if we are unable to achieve relatively high capacity utilization rates, our earnings and
profitability may be adversely affected.

Our significant amount of indebtedness and interest expense will limit our cash flow and
could adversely affect our operations.

We have a significant level of debt and interest expense. As of
December 31, 2014, we had approximately NT$4,560 million (US$144 million) and NT$3,276 million (US$104 million) outstanding long-term and short-term indebtedness, respectively. Our long-term indebtedness as of December 31, 2014,
represented bank loans with an interest rate between 1.8947% and 3.16545%. As of December 31, 2014, NT$6,068 million (US$192 million) of our indebtedness was secured by collateral comprised of assets owned by ChipMOS TECHNOLOGIES INC., or
ChipMOS Taiwan and ChipMOS TECHNOLOGIES (Shanghai) LTD., or ChipMOS Shanghai.

##### Table of Contents

Our significant indebtedness poses risks to our business, including the risks that:



| |  |  | we may have to use a substantial portion of our consolidated cash flow from operations to pay principal and interest on our debt, thereby reducing the
funds available for working capital, capital expenditures, acquisitions and other general corporate purposes;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | insufficient cash flow from operations may force us to sell assets, or seek additional capital, which we may be unable to do at all or on terms
favorable to us;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to sell assets or seek additional capital may be adversely affected by security interests in our assets granted to our lenders as
collateral;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our level of indebtedness may make us more vulnerable to economic or industry downturns; and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | our debt service obligations increase our vulnerabilities to competitive pressures, because many of our competitors may be less leveraged than we are.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------

For additional information on our indebtedness, see Item 5. Operating and Financial Review and
ProspectsLiquidity and Capital Resources.

Our results of operations may fluctuate significantly and may cause the market
price of our common shares to be volatile.

Our results of operations have varied significantly from period to period
and may continue to vary in the future. Among the more important factors affecting our quarterly and annual results of operations are the following:



| |  |  | our ability to accurately predict customer demand, as we must commit significant capital expenditures in anticipation of future orders;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to quickly adjust to unanticipated declines or shortfalls in demand and market prices for our testing and assembly services, due to our
high percentage of fixed costs;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in prices for our testing and assembly services;
| | - |  | --------------------------------------------------------



| |  |  | volume of orders relative to our testing and assembly capacity;
| | - |  | ---------------------------------------------------------------



| |  |  | capital expenditures and production uncertainties relating to the roll-out of new testing or assembly services;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | our ability to obtain adequate testing and assembly equipment on a timely basis;
| | - |  | --------------------------------------------------------------------------------



| |  |  | changes in costs and availability of raw materials, equipment and labor;
| | - |  | ------------------------------------------------------------------------



| |  |  | changes in our product mix; and
| | - |  | -------------------------------



| |  |  | earthquakes, drought and other natural disasters, as well as industrial accidents.
| | - |  | ----------------------------------------------------------------------------------

Because of the factors listed above, our future results of operations or growth rates may be below the expectations of research analysts
and investors. If so, the market price of our common shares, and the market value of your investment, may fall.

We depend on key
customers for a substantial portion of our revenue and a loss of, or deterioration of the business from, or delayed payment by, any one of these customers could result in decreased revenue and materially adversely affect our results of operations
and financial condition.

We depend on a small group of customers for a substantial portion of our business. In 2014,
our top five customers, collectively accounted for 60% of our revenue. As part of our strategy, we have been focusing on sales to key customers through long-term service agreements. We also focus on our business with smaller customers and customers
who do not place orders on a regular basis. We expect that we will continue to depend on a relatively limited number of customers for a significant portion of our revenue. Any adverse development in our key customers operations, competitive
position or customer base could materially reduce our revenue and adversely affect our business and profitability.

Since
semiconductor companies generally rely on service providers with whom they have established relationships to meet their testing and assembly needs for their applications and new customers usually require us to pass a lengthy and rigorous
qualification process, if we lose any of our key customers, we may not be able to replace them in a timely manner. We cannot assure you that receivable collection difficulties experienced by us will not occur in the future. If any of our key
customers reduces or cancels its orders or terminates existing contractual arrangements, and if we are unable to attract new customers and establish new contractual arrangements with existing or new customers, our revenue could be reduced and our
business and results of operations may be materially adversely affected.

##### Table of Contents

Because of our high fixed costs, if we are unable to achieve relatively high capacity utilization
rates, our earnings and profitability may be adversely affected.

Our operations are characterized by a high
proportion of fixed costs. For memory and logic/mixed-signal semiconductor testing services, our fixed costs represented 57% and 47% of our total cost of revenue in 2013 and 2014, respectively. For memory and logic/mixed-signal semiconductor
assembly services, our fixed costs represented 20% and 19% of our total cost of revenue in 2013 and 2014, respectively. For LCD and other flat-panel display driver semiconductor testing and assembly services, our fixed costs represented 45% and 46%
of our total cost of revenue in 2013 and 2014, respectively. For bumping services, our fixed costs represented 19% and 19% of our total cost of revenue in 2013 and 2014, respectively. Our profitability depends in part not only on absolute pricing
levels for our services, but also on the utilization rates for our testing and assembly equipment, commonly referred to as capacity utilization rates. Increases or decreases in our capacity utilization rates can significantly affect our
gross margins as unit costs generally decrease as the fixed costs are allocated over a larger number of units. In the past, our capacity utilization rates have fluctuated significantly as a result of the fluctuations in the market demand for
semiconductors. If we fail to increase or maintain our capacity utilization rates, our earnings and profitability may be adversely affected. In addition, we have entered into various long-term assembly and testing services agreements with certain of
our customers that may require us to incur significant capital expenditures. If we are unable to achieve high capacity utilization rates for the equipment purchased pursuant to these agreements, our gross margins may be materially and adversely
affected.

The testing and assembly process is complex and our production yields and customer relationships may suffer as a result of
defects or malfunctions in our testing and assembly equipment and the introduction of new packages.

Semiconductor
testing and assembly are complex processes that require significant technological and process expertise. Semiconductor testing involves sophisticated testing equipment and computer software. We develop computer software to test our customers
semiconductors. We also develop conversion software programs that enable us to test semiconductors on different types of testers. Similar to most software programs, these software programs are complex and may contain programming errors or
bugs. In addition, the testing process is subject to human error by our employees who operate our testing equipment and related software. Any significant defect in our testing or conversion software, malfunction in our testing equipment
or human error could reduce our production yields and damage our customer relationships.

The assembly process involves a
number of steps, each of which must be completed with precision. Defective packages primarily result from:



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



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



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



| |  |  | defective raw materials; or
| | - |  | ---------------------------



| |  |  | defective plating services.
| | - |  | ---------------------------

These and other factors have, from time to time, contributed to lower production yields. They may do so in the future, particularly as we expand our capacity or change our processing steps. In addition,
to be competitive, we must continue to expand our offering of packages. Our production yields on new packages typically are significantly lower than our production yields on our more established packages. Our failure to maintain high standards or
acceptable production yields, if significant and prolonged, could result in a loss of customers, increased costs of production, delays, substantial amounts of returned goods and related claims by customers. Further, to the extent our customers have
set target production yields, we may be required to compensate our customers in a pre-agreed manner. Any of these problems could materially adversely affect our business reputation and result in reduced revenue and profitability.

Because of the highly cyclical nature of our industry, our capital requirements are difficult to plan. If we cannot obtain additional capital when
we need it, we may not be able to maintain or increase our current growth rate and our profits will suffer.

As our
industry is highly cyclical and rapidly changing, our capital requirements are difficult to plan. To remain competitive, we may need capital to fund the expansion of our facilities as well as to fund our equipment purchases and research and
development activities. To meet our liquidity, capital spending and other capital needs, we have taken and plan to take certain measures to generate additional working capital and to save cash. See Item 5. Operating and Financial Review and
ProspectsLiquidity and Capital Resources. We cannot assure you that these plans and measures will be implemented or will provide sufficient sources of capital.

In addition, future capacity expansions or market or other developments may require additional funding. Our ability to obtain external financing in the future depends on a number of factors, many of which
are beyond our control. They include:



| |  |  | our future financial condition, results of operations and cash flows;
| | - |  | ---------------------------------------------------------------------



| |  |  | general market conditions for financing activities by semiconductor testing and assembly companies; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | economic, political and other conditions in Taiwan and elsewhere.
| | - |  | -----------------------------------------------------------------

##### Table of Contents

If we are unable to obtain funding in a timely manner or on acceptable terms, our growth
prospects and potential future profitability will suffer.

Disputes over intellectual property rights could be costly, deprive us of
technologies necessary for us to stay competitive, render us unable to provide some of our services and reduce our opportunities to generate revenue.

Our ability to compete successfully and achieve future growth will depend, in part, on our ability to protect our proprietary technologies and to secure, on commercially acceptable terms, critical
technologies that we do not own. We cannot assure you that we will be able to independently develop, or secure from any third party, the technologies required for our testing and assembly services. Our failure to successfully obtain these
technologies may seriously harm our competitive position and render us unable to provide some of our services.

Our ability to
compete successfully also depends on our ability to operate without infringing upon the proprietary rights of others. The semiconductor testing and assembly industry is characterized by frequent litigation regarding patent and other intellectual
property rights. We may incur legal liabilities if we infringe upon the intellectual property or other proprietary rights of others. We are not able to ascertain what patent applications have been filed in the United States or elsewhere, however,
until they are granted. If any third party succeeds in its intellectual property infringement claims against us or our customers, we could be required to:



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



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



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



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

Any one of these developments could impose substantial financial and administrative burdens on us and hinder our business. We are, from
time to time, involved in litigation in respect of intellectual property rights. Any litigation, whether as plaintiff or defendant, is costly and diverts our resources. If we fail to obtain necessary licenses on commercially reasonable terms or if
litigation, regardless of the outcome, relating to patent infringement or other intellectual property matters occurs, our costs could be substantially increased to impact our margins. Any such litigation could also prevent us from testing and
assembling particular products or using particular technologies, which could reduce our opportunities to generate revenue. For more information on litigation in respect of intellectual property rights, see Item 8. Financial
InformationLegal Proceedings.

If we are unable to obtain raw materials and other necessary inputs from our suppliers in a
timely and cost-effective manner, our production schedules would be delayed and we may lose customers and growth opportunities and become less profitable.

Our operations require us to obtain sufficient quantities of raw materials at acceptable prices in a timely and cost-effective manner. We source most of our raw materials, including critical materials
like leadframes, organic substrates, epoxy, gold wire and molding compound for assembly, and tapes for TCP/COF, from a limited group of suppliers. We purchase all of our materials on a purchase order basis and have no long-term contracts with any of
our suppliers. From time to time, suppliers have extended lead times, increased the price or limited the supply of required materials to us because of market shortages. Consequently, we may, from time to time, experience difficulty in obtaining
sufficient 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. Although we typically maintain at least two suppliers
for each key raw material, we cannot assure you that we will be able to obtain sufficient quantities of raw materials and other supplies of an acceptable quality in the future. It usually takes from three to six months to switch from one supplier to
another, depending on the complexity of the raw material. If we are unable to obtain raw materials and other necessary inputs in a timely and cost-effective manner, we may need to delay our production and delivery schedules, which may result in the
loss of business and growth opportunities and could reduce our profitability.

If we are unable to obtain additional testing and
assembly equipment or facilities in a timely manner and at a reasonable cost, we may be unable to fulfill our customers orders and may become less competitive and less profitable.

The semiconductor testing and assembly business is capital intensive and requires significant investment in expensive equipment
manufactured by a limited number of suppliers. The market for semiconductor testing and assembly equipment is characterized, from time to time, by intense demand, limited supply and long delivery cycles. Our operations and expansion plans depend on
our ability to obtain equipment from a limited number of suppliers in a timely and cost-effective manner. We have no binding supply agreements with any of our suppliers and we acquire our testing and assembly equipment on a purchase order basis,
which exposes us to changing market conditions and other significant risks. Semiconductor testing and assembly also requires us to operate sizeable facilities. If we are unable to obtain equipment or facilities in a timely manner, we may be unable
to fulfill our customers orders, which could negatively impact our financial condition and results of operations as well as our growth prospects. Previously we have committed to acquire certain wafer sorting testers and probers under our
long-term service agreement with Spansion LLC (Spansion). We terminated that agreement and commitment on February 19, 2009, after Spansion defaulted on its payment obligations. Currently, we do not have any long-term service
agreements that require our commitment to acquire additional testing and assembly equipment or facilities, however we cannot assure you that such commitment will not be made in the future. See Item 4. Information on the
CompanyCustomers.

If we are unable to manage the expansion of our operations and resources effectively, our growth
prospects may be limited and our future profitability may be reduced.

We expect to continue to expand our operations
and increase the number of our employees. Rapid expansion puts a strain on our managerial, technical, financial, operational and other resources. As a result of our expansion, we will need to implement additional operational and financial controls
and hire and train additional personnel. We cannot assure you that we will be able to do so effectively in the future, and our failure to do so could jeopardize our expansion plans and seriously harm our operations.

Bermuda law may be less protective of shareholder rights than laws of the United States or other jurisdictions.

Our corporate affairs are governed by our memorandum of association, our bye-laws and laws governing corporations incorporated in
Bermuda. Shareholder suits such as class actions (as these terms are understood with respect to corporations incorporated in the United States) are generally not available in Bermuda. Therefore, our shareholders may be less able under Bermuda law
than they would be under the laws of the United States or other jurisdictions to protect their interests in connection with actions by our management, members of our board of directors or our controlling shareholder.

It may be difficult to bring and enforce suits against us in the United States.

We are incorporated in Bermuda and a majority of our directors and most of our officers are not residents of the United States. A
substantial portion of our assets is located outside the United States. As a result, it may be difficult for our shareholders to serve notice of a lawsuit on us or our directors and officers within the United States. Because most of our assets are
located outside the United States, it may be difficult for our shareholders to enforce in the United States judgments of United States courts. Appleby, our Bermuda counsel, has advised us that there is some uncertainty as to the enforcement in
Bermuda, in original actions or in actions for enforcement of judgments of United States courts, of liabilities predicated upon United States federal securities laws, although final and conclusive judgments in the courts of the United States against
our company under which a sum of money is payable (not being a sum of money payable in respect of taxes or other charges of a like nature, in respect of a fine or other penalty, or in respect of multiple damages as defined in The Protection of
Trading Interests Act 1981 of Bermuda) would be enforced by the Supreme Court of Bermuda as a debt against our company, subject to certain conditions and exceptions.

Investor confidence and the market price of our common shares may be adversely impacted if we or our independent public registered accounting firm is unable to conclude that our internal control
over our financial reporting is effective as required by Section 404 of the Sarbanes-Oxley Act of 2002.

We are
subject to the Securities and Exchange Commissions (SECs) reporting obligations, and beginning in our Annual Report on Form 20-F for the year ended December 31, 2006, we have been required by the SEC, as directed by
Section 404 of the Sarbanes-Oxley Act of 2002, to include a report of management on our internal control over financial reporting in our Annual Report on Form 20-F that contains an assessment by management of the effectiveness of our internal
control over financial reporting. Beginning in fiscal year 2007, our independent public registered accounting firm has audited the effectiveness of our internal control over financial reporting. Although our management concluded that our internal
controls are effective in this Annual Report on Form 20-F, and our independent public registered accounting firm has rendered its opinion that we maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2014, based on criteria set forth in Internal Control  Integrated Framework (2013) issued by Committee of Sponsoring Organization of the Treadway Commission (COSO), our management may not conclude that our internal
controls are effective in the future. Moreover, even if our management concludes that our internal controls over our financial reporting are effective our independent public registered accounting firm may disagree. If our independent public
registered accounting firm is not satisfied with our internal controls over our financial reporting or the level at which our controls are documented, designed, operated or reviewed, or if the independent public registered accounting firm interprets
the requirements, rules or regulations differently from us, it may decline to attest to our managements assessment or may issue an adverse opinion in the future. Any of these possible outcomes could result in an adverse reaction in the
financial marketplace due to a loss of investor confidence in the reliability of our consolidated financial statements, which ultimately could negatively impact the market prices of our common shares.

Any environmental claims or failure to comply with any present or future environmental regulations, or
any new environmental regulations, may require us to spend additional funds, may impose significant liability on us for present, past or future actions, and may dramatically increase the cost of providing our services to our customers.

We are subject to various laws and regulations relating to the use, storage, discharge and disposal of chemical
by-products of, and water used in, our assembly and gold bumping processes. Although we have not suffered material environmental claims in the past, a failure or a claim that we have failed to comply with any present or future regulations could
result in the assessment of damages or imposition of fines against us, suspension of production or a cessation of our operations or negative publicity. New regulations could require us to acquire costly equipment or to incur other significant
expenses. Any failure on our part to control the use of, or adequately restrict the discharge of, hazardous substances could subject us to future liabilities that may materially reduce our earnings.

Fluctuations in exchange rates could result in foreign exchange losses.

Currently, most of our revenue is denominated in NT dollars. Our cost of revenue and operating expenses, on the other hand, are incurred
in several currencies, including NT dollars, Japanese yen, US dollars and Renminbi, or RMB. In addition, a substantial portion of our capital expenditures, primarily for the purchase of testing and assembly equipment, has been, and is expected to
continue to be, denominated in Japanese yen with much of the remainder in US dollars. We also have debt denominated in NT dollars, Japanese yen, US dollars and RMB. Fluctuations in exchange rates, primarily among the US dollar, the NT dollar and the
Japanese yen, will affect our costs and operating margins in NT dollar terms. In addition, these fluctuations could result in exchange losses and increased costs in NT dollar terms. Despite selective hedging and other techniques implemented by us,
fluctuations in exchange rates have affected, and may continue to affect, our financial condition and results of operations.

We may not
be successful in our acquisitions, investments, joint ventures and dispositions, and may therefore be unable to implement fully our business strategy.

As part of our growth strategy, we may make acquisitions and investments in companies and businesses, establish joint ventures or make dispositions of our interests. For example, in February 2010, we
agreed to sell 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision Industries Co., Ltd. (Siliconware Precision) and the transaction was completed in January 2011. In April 2013, as part of ChipMOS Taiwans
listing plan on the Taiwan Stock Exchange (TWSE), we completed the sale of 6.5 million or 0.8% of the total number of ChipMOS Taiwans outstanding shares to ChipMOS Taiwans underwriters and to certain others, including
non-US employees of ChipMOS Taiwan. From September to October 2013, we sold 180 million or 21.4% of the total number of ChipMOS Taiwans outstanding shares to investors. After the completion of the aforesaid sales, the Company held
approximately 523 million ChipMOS Taiwan shares, representing 62.1% of the total number of ChipMOS Taiwans outstanding shares. On April 9, 2014, ChipMOS Bermuda further sold 1.3 million ChipMOS Taiwan shares as green
shoe option to market investors. ChipMOS Taiwan became listed and commenced trading on the main board of TWSE on April 11, 2014. As of the date of this Annual Report on Form 20-F, we continue to own approximately 522 million or 60.4%
of ChipMOS Taiwans outstanding shares without any green shoe option outstanding. See Risk Relating to Our Corporate StructureChipMOS Taiwans ability to maintain its listing and trading status on the Taiwan
Stock Exchange is dependent on factors outside of the Company or ChipMOS Taiwans control and satisfaction of stock exchange requirements. ChipMOS Taiwan may not be able to overcome such factors that disrupt its trading status on the main board
of Taiwan Stock Exchange or satisfy other eligibility requirements that may be required of it in the future.

In
November 2012, pursuant to a Registration Statement on Form F-3 declared effective on September 5, 2012, ThaiLin Semiconductor Corp. (ThaiLin) sold 2,000,000 of our common shares under a secondary offering (the Secondary
Offering). In May 2013, ThaiLin completed its sale of 380,506 of our common shares to Tokyo Seimitsu Co., Ltd. (Tokyo Seimitsu). In November 2013 and January 2014, ThaiLin sold 2,000,000 and 2,093,705 of our commons shares back to
ChipMOS Bermuda, respectively. In September 2014, Siliconware Precision sold 1,000,000 of our common shares back to ChipMOS Bermuda under the share purchase agreement entered in August 2014. The success of our acquisitions, investments, joint
ventures and dispositions depends on a number of factors, including:



| |  |  | our ability to identify suitable investment, acquisition, joint venture or disposition opportunities;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | our ability to reach an agreement for an acquisition, investment, joint venture or disposition opportunity on terms that are satisfactory to us or at
all;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the extent to which we are able to exercise control over the acquired or joint venture company;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | our ability to align the economic, business or other strategic objectives and goals of the acquired company with those of our company; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to successfully integrate the acquired or joint venture company or business with our company.

##### Table of Contents

If we are unsuccessful in our acquisitions, investments, joint ventures and dispositions, we
may not be able to implement fully our business strategy to maintain or grow our business.

We depend on key personnel, and our revenue
could decrease and our costs could increase if we lose their services.

We depend on the continued service of our
executive officers and skilled engineering, technical and other personnel. We will also be required to hire a substantially greater number of skilled employees in connection with our expansion plans. In particular, we depend on a number of skilled
employees in connection with our LCD and other flat-panel display driver semiconductor testing and assembly services, and the competition for such employees in Taiwan and Mainland China is intense. We may not be able to either retain our present
personnel or attract additional qualified personnel as and when needed. Moreover, we do not carry key person insurance for any of our executive officers nor do we have employment contracts with any of our executive officers or employees, and, as a
result, none of our executive officers or employees is bound by any non-competition agreement. If we lose any of our key personnel, it could be very difficult to find and integrate replacement personnel, which could affect our ability to provide our
services, resulting in reduced revenue and earnings. In addition, we may need to increase employee compensation levels in order to retain our existing officers and employees and to attract additional personnel. As of March 31, 2015, 17.5% of
the workforce at our facilities are foreign workers employed by us under work permits that are subject to government regulations on renewal and other terms. Consequently, if the regulations in Taiwan relating to the employment of foreign workers
were to become significantly more restrictive or if we are otherwise unable to attract or retain these workers at reasonable cost, we may be unable to maintain or increase our level of services and may suffer reduced revenue and earnings.

If our security measures are breached and unauthorized access is obtained to our information technology systems, we may lose
proprietary data.

Our security measures may be breached as a result of third-party action, including computer
hackers, employees error, malfeasance or otherwise, and result in unauthorized access to our customers data or our data, including our intellectual property and other confidential business information, or our information technology systems.
Because the techniques used to obtain unauthorized access, or to sabotage systems, change frequently, we may be unable to anticipate these techniques or to implement adequate preventative measures. Any security breach could result in disclosure of
our trade secrets, confidential customer, supplier or employee data, which could result in legal liability, harm to our reputation and otherwise harm our business.

Risk Relating to Our Relationship with Mosel

ChipMOS Taiwan entered into certain
transactions that, if determined to have constituted impermissible financings or purchases of assets or equity of Mosel under ROC law, could result in the resignations of members of our management. As a result, our business operations could be
disrupted and the market price of our common shares could decline.

ROC law limits the ability of a company
incorporated in Taiwan to purchase any equity interest in companies, directly or indirectly, holding more than 50% of its issued and outstanding voting securities or registered capital or to provide loans or other financing to any company. ChipMOS
Taiwan purchased NT$242 million worth of Mosel Vitelic Inc. (Mosel) shares in 2002. Lee and Li, our ROC special counsel, has advised us that these purchases do not violate relevant ROC law that prohibits a subsidiary from buying or
taking collateral in shares of companies holding, directly or indirectly, more than 50% of its issued and outstanding voting securities or registered capital, because Mosels indirect interest (calculated as the product of (i) Mosels
percentage interest in ChipMOS Bermuda and (ii) ChipMOS Bermudas percentage interest in ChipMOS Taiwan) in ChipMOS Taiwan was less than 50% and ChipMOS Bermuda is incorporated outside of Taiwan. In 2005, ChipMOS Taiwan disposed of NT$84
million of Mosel shares, and in August 2006, ChipMOS Taiwan further disposed of the remaining Mosel shares for approximately NT$30 million. ChipMOS Taiwan no longer owns any Mosel shares. Lee and Li has advised that under relevant ROC law, there is
no similar restriction or limitation on a subsidiarys disposal of its parents equity shares, if the previous acquisitions of such shares complied with relevant ROC law. However, we understand that there is no applicable judicial
precedent and there is some doubt as to how a court would rule if presented with the situation.

If it were to be determined
that any of the transactions described above constituted an impermissible financing or purchase of assets of Mosel by ChipMOS Taiwan or an impermissible purchase of Mosels equity by ChipMOS Taiwan, then ChipMOS Taiwans then chairman and
any responsible officers would be jointly and severally liable to ChipMOS Taiwan for any losses suffered by ChipMOS Taiwan and may also be severally liable criminally for any breach of fiduciary duties that resulted in losses and damages suffered by
ChipMOS Taiwan. Moreover, certain of these transactions may not have been in full compliance with ChipMOS Taiwans then applicable internal procedures due to the failure to have received an appropriate valuation opinion prior to entering into
such purchases. The failure to comply fully with ChipMOS Taiwans then applicable internal procedures could constitute evidence of a failure by the then chairman of ChipMOS Taiwan and responsible officers to comply fully with their fiduciary
duties, which could result in them being held criminally liable for any breach of fiduciary duties that resulted in losses and damages to ChipMOS Taiwan. If members of our current management were held to have breached their fiduciary duties or
become criminally liable for the transactions described above, they may become obliged, whether under law or otherwise, to resign from their respective positions at ChipMOS Bermuda and our affiliates. Any loss of the services of these persons could
disrupt our business, damage our reputation, and cause the market price of our common shares to decline.

Risks Relating to Countries in Which We Conduct Operations

ROC laws and regulations limit or prohibit certain technology cooperation between ROC persons or entities with PRC persons or entities, and our
current technology transfer arrangements between ChipMOS Bermuda and ChipMOS Shanghai may be found to be in violation of any such limitation or prohibition, which may result in a fine of between NT$50 thousand and NT$25 million and the termination
of such technology transfer arrangements and therefore have a material adverse effect on the operations of ChipMOS Shanghai and our financial condition and results of operations.

ROC laws and regulations previously prohibited any transfer of semiconductor testing and assembly technologies to any person or entity
located in Mainland China, except for transfers involving certain low-end semiconductor testing and assembly technologies, such as conventional wire bond assembly technology, if certain requirements are met. The ROC Ministry of Economic Affairs has
the ultimate administrative authority in interpreting such laws and regulations. In February 2010, these restrictions have been relaxed, so that ROC entities may transfer semiconductor testing and assembly technologies to any person or entity
located in Mainland China after they have obtained approval from the Investment Commission of the ROC Ministry of Economic Affairs, or the ICM. Under a technology transfer agreement, dated August 1, 2002, ChipMOS Bermuda licensed to ChipMOS
Shanghai certain testing and assembly-related technologies that were then controlled by ChipMOS Bermuda, which included technologies that were licensed to ChipMOS Bermuda by ChipMOS Taiwan. ChipMOS Bermuda will continue to license such technologies
to ChipMOS Shanghai pursuant to a technology transfer agreement dated October 3, 2011 with effective date on August 1, 2012. ChipMOS Bermuda also provided ChipMOS Shanghai with technical support and consulting services under this
agreement. On April 7, 2004, ChipMOS Bermuda entered into an assignment agreement with ChipMOS Taiwan, pursuant to which ChipMOS Taiwan transferred all of the technologies it owned as of that date to ChipMOS Bermuda, including those previously
licensed to ChipMOS Bermuda. On April 12, 2007, ChipMOS Bermuda entered into an assignment agreement with ChipMOS Taiwan, pursuant to which ChipMOS Taiwan assigned and transferred fifty percent of the title to ownership of and interest in all
of the technologies and intellectual property it owned as of that date to ChipMOS Bermuda.

In the opinion of Lee and Li, our
ROC special counsel, our technology transfer arrangements as described above are in compliance with all applicable ROC laws and regulations. However, substantial uncertainties remain regarding the interpretation and application of those laws and
regulations. Accordingly, we cannot assure you that ROC regulatory authorities will not take a view contrary to the opinion of our ROC special counsel. If ChipMOS Taiwan were determined to be in violation of applicable ROC laws and regulations
governing technology cooperation with PRC persons and entities, ChipMOS Taiwan may be subject to a fine of between NT$50 thousand and NT$25 million and may be ordered by the ICM to terminate or rectify such activity within a specified period of
time. Any termination of our current technology transfer to ChipMOS Shanghai could materially adversely affect our Mainland China operations and our financial condition, results of operations or prospects, as well as the market price of our common
shares.

Our ability to direct the operations we conduct through our subsidiaries and affiliated companies that we do not fully own may
be limited by legal duties owed to other shareholders of such companies.

Certain of our operations are conducted
through companies that we do not fully own. For example, certain current consolidated operations are conducted through ChipMOS Taiwan, our 60.4% subsidiary as of March 31, 2015, ThaiLin, ChipMOS Taiwans 47.5% owned subsidiary as of
March 31, 2015, and ChipMOS Shanghai, ThaiLins indirectly wholly-owned subsidiary as of March 31, 2015. On November 12, 2014, ChipMOS Taiwan made announcement for the contemplated merger with ThaiLin. Upon the closing of the
merger, ThaiLin will be merged with ChipMOS Taiwan. As a result of the merger, ChipMOS Taiwan will become our 58.0% owned subsidiary and ChipMOS Shanghai will become ChipMOS Taiwans indirectly wholly-owned subsidiary through MODERN MIND
TECHNOLOGY LIMITED, (Modern Mind). For more information, please see Pending Merger with ThaiLin may or may not complete or achieve the expected synergy, efficiency and effectiveness. We also conduct other activities
through our affiliated entities. See also Risk Relating to Our Corporate StructureChipMOS Taiwans ability to maintain its listing and trading status on the Taiwan Stock Exchange is dependent on factors outside of the Company
or ChipMOS Taiwans control and satisfaction of stock exchange requirements. ChipMOS Taiwan may not be able to overcome such factors that disrupt its trading status on the main board of Taiwan Stock Exchange or satisfy other eligibility
requirements that may be required of it in the future and Item 7. Major Shareholders and Related Party TransactionsRelated Party Transactions.

In accordance with the various laws of the relevant jurisdictions in which our subsidiaries and affiliates are organized, each of our subsidiaries and affiliates and their respective directors owe various
duties to their respective shareholders. As a result, the actions we wish our subsidiaries or affiliates to take could be in conflict with their or their directors legal duties owed to their other shareholders. When those conflicts arise, our
ability to cause our subsidiaries or affiliates to take the action that we desire may be limited.

Any future outbreak of health epidemics and outbreaks of contagious diseases, including avian
influenza, swine flu, Severe Acute Respiratory Syndrome, or Ebola virus disease, may materially affect our operations and business.

Influenza viruses circulating in animals pose threats to human health. Humans can become ill when infected with viruses from animal sources, such as avian influenza virus subtypes H5N1, H9N2 and H7N9 and
swine influenza virus subtypes H1N1 and H3N2. An outbreak of a contagious disease such as New Influenza A or more commonly known as the bird flu and swine flu, Severe Acute Respiratory Syndrome (SARS), or avian influenza with
virus subtype H7N9, for which there is inadequate treatment or no known cure or vaccine, may potentially result in a quarantine of infected employees and related persons, and adversely affect our operations at one or more of our facilities or the
operations of our customers or suppliers. We cannot predict the impact that any further future outbreak of the aforementioned influenza viruses or other diseases could have on our business and results of operations.

Also, according to World Health Organization, the current outbreak of in West Africa is the largest and most complex Ebola virus disease
(EVD) outbreak since the Ebola virus was first discovered in 1976. There have been more cases and deaths in this outbreak than all others combined. It has also spread between countries starting in Guinea then spreading across land borders to Sierra
Leone and Liberia, by air to Nigeria, and by land to Senegal. People remain infectious as long as their blood and body fluids, including semen and breast milk, contain the virus. Men who have recovered from the disease can still transmit the virus
through their semen for up to 7 weeks after recovery from illness. There is as yet no proven treatment available for EVD. As such, we cannot predict the impact that any future outbreak of EVD could have on our business and results of operations.

We face substantial political risk associated with doing business in Taiwan, particularly due to recent domestic political events and
the strained relations between the Republic of China and the Peoples Republic of China, that could negatively affect our business and the market price of our common shares.

Our principal executive offices and most of our testing and assembly facilities are located in Taiwan. As a result, our business,
financial condition and results of operations and the market price of our common shares may be affected by changes in ROC governmental policies, as well as social instability and diplomatic and social developments in or affecting Taiwan which are
beyond our control. For example, the ROC has a unique international political status. The PRC government regards Taiwan as a renegade province and does not recognize the legitimacy of the ROC as an independent country. Although significant economic
and cultural relations have been positively strengthened in recent years between the ROC and the PRC, relations have often been strained. In March 2005, the PRC government enacted the Anti-Secession Law codifying its policy of retaining
the right to use military force to gain control over Taiwan, particularly under what it considers as highly provocative circumstances, such as a declaration of independence by Taiwan or the refusal by the ROC to accept the PRCs stated
One China policy. On March 18, 2014, students and certain civic groups initiated the Sunflower Student Movement as a protest movement in the Legislative Yuan and, later, also the Executive Yuan of the Republic of China (Taiwan). The
activists protested the passing of the Cross-Strait Service Trade Agreement (CSSTA) proposed by the ruling party Kuomintang (KMT) at the legislature without a clause-by-clause review. The protesters perceive the passage of
CSSTA failed to meet the required formal procedures and that the ratification of CSSTA with PRC would hurt Taiwans economy and leave it vulnerable, among others, to political pressure from Beijing, while the supporters view the trade pact
would allow the two sides to conduct business operations more freely in each others services market. The Sunflower Student Movement marks the first time that legislature has been occupied by citizens in the history of Taiwan. On April 10,
2014, the 24-days occupation of the Legislative Yuan has concluded. The CSSTA has been put on hold ever since the Sunflower Student Movement.

Past developments related to the interaction between the ROC and the PRC have on occasion depressed the market prices of the securities of Taiwanese or Taiwan-related companies, including our own. We
cannot assure you any contentious situations between Taiwan and China will resolve in maintaining the current status quo or remain peaceful. Relations between the ROC and the PRC and other factors affecting military, political or economic stability
in Taiwan could have a material adverse effect on our financial condition and results of operations, as well as the market price and the liquidity of our common shares.

The business and operations of our business associates and our own business operations are vulnerable to disruptions that may be caused by natural disasters and other events.

We currently provide most of our testing services through our facilities in the Hsinchu Industrial Park and the Hsinchu Science Park in
Taiwan and the Shanghai Qingpu Industrial Zone, and all of our assembly services through our facilities in the Southern Taiwan Science Park and the Shanghai Qingpu Industrial Zone. Significant damage or other impediments to these facilities as a
result of natural disasters, industrial strikes or industrial accidents could significantly increase our operating costs.

Certain regions we operate in are particularly susceptible to earthquakes and associated
natural disasters. For example, in late 1999, Taiwan suffered severe earthquakes which caused significant property damages and loss of life, particularly in the central part of Taiwan. The earthquakes damaged production facilities and adversely
affected the operations of many companies involved in the semiconductor and other industries. We experienced an aggregate of NT$8 million in damages to our machinery and equipment, facilities, inventory and five days of delay in production schedule
as a result of the event. In March 2011, Sendai of Japan registered an earthquake of 9.0 Mw (moment magnitude scale) off the coast of Japan (the Sendai Earthquake). The Sendai Earthquake was recorded as most powerful earthquake to hit
Japan and the fourth most powerful earthquake in the world. The earthquake triggered tsunami warnings and evacuations along Japans Pacific coast and in at least 20 countries, including Taiwan and Mainland China. In April 2013, an earthquake
registering a magnitude of approximately 6.6-7.0 Mw with epicenter located in Lushan County, Yaan, Sichuan (the Lushan Earthquake). ReliefWeb, part of the United Nations Office for the Coordination of Humanitarian Affairs (OCHA)
released information on July 23, 2013 confirming 196 deaths and up to 2 persons missing and 14,785 injured victim reports.

In January and February 2008, certain parts of Mainland China, particularly in the southern, central and eastern regions, experienced
reportedly the most severe winter in the country in recent decades, which resulted in significant and extensive damages to factories, power lines, homes, automobiles, crops and other properties, blackouts, transportation and communications
disruptions and other losses in the affected areas. In addition, in May 2008, certain semiconductor companies with facilities in eastern Mainland China experienced production disruption reportedly due to power outages caused by the failure of
certain electricity supply system in the area where the plants are located. We cannot assure you that our facilities in the Shanghai Qingpu Industrial Zone will not be adversely affected by future snowstorms, power outages, earthquakes or other
similar events.

Natural disasters and other events like aforementioned events cause severe property damages to townships,
infrastructures and death and injuries to Civilians. In Sendai Earthquake, many electrical generators were disabled, and at least three nuclear power plant reactors partially melted down and experienced a chemical explosion extensively damaging
surrounding buildings. We cannot assure you that our production facilities, operations and market located in Taiwan and Mainland China will not be adversely affected as result of the events that take place overseas like the Sendai Earthquake,
including radiation emission from the damaged nuclear power plants or subsequent future earthquakes that may take place.

The
production facilities of many of our suppliers, customers and providers of complementary semiconductor manufacturing services, including foundries, are located in Taiwan and Mainland China. If our customers are adversely affected by natural
disasters or other events occurring in or affecting these geographic areas, 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 by such events, our production schedule could be halted or delayed. As a result, a major earthquake, snowstorm, other natural disaster, industrial strike, industrial accident or other disruptive event occurring in or affecting Taiwan or
Mainland China could severely disrupt our normal operation of business and have a material adverse effect on our financial condition and results of operations.

Any future outbreak of radiation-related disease as a result of nuclear power plant reactors damage caused by the Sendai Earthquake may materially adversely affect our operations and business.

The Sendai Earthquake raises tremendous concerns about the possible effects of radiation emission from the damaged
nuclear power plants. Japanese official authorities are working with experts in assessing the risk and determining the best courses of actions to implement to escape harmful radiation. The potential health effects due to exposure to harmful
radiation may be temporary or permanent harmful effects in nature.

Multiple radioactive gases could possibly be emitted in a
situation where uranium attains a meltdown state, which is a severe overheating of the core of a nuclear reactor, in which the core melts and radiation and heat are caused to escape. This would occur if the containment system partially
or fully fails. The particles that are released with the gases due to the meltdown would be the spewed particles of iodine-131, strontium-90 and cesium-137. These might enter into a human by being swallowed, absorbed through the skin, or inhaled.
Depending on the chemical characteristics of each of these and their predilection for certain body tissues, they could cause cancers of such organs as bones, soft tissues near bones, thyroid gland, and the bone marrow (typically known as leukemia).

Acute or very high level radiation exposure can cause a person to become very ill or to die quickly. Ionizing radiation,
which is defined as high-energy particles or electromagnetic waves that can break chemical bonds, damage humans by disrupting cellular function, particularly in tissues with rapid growth and turnover of cells. Intense, high level and/or excessive
radiation exposure may result in acute radiation syndrome whereby harmful effects to the human body may be evidenced by skin burns, internal organ deterioration, bleeding, vomiting, bone marrow distortion and deaths. If the radiation exposure is
less intense and/or more prolonged at a lower level, then the central nervous system, kidneys, thyroid gland, and liver may be affected. Cancer is the most well-known effect, and may affect virtually any significantly exposed tissue.

Certain health effects due to exposure to harmful radiation does not have adequate treatment
or known cure or vaccine, consequently, may potentially result in a quarantine of infected employees and related persons, and adversely affect our operations at one or more of our facilities or the operations of our customers or suppliers. We cannot
predict the probability of any future outbreak of radiation related diseases as a possible result of nuclear power plants damage caused by the Sendai Earthquake or the extent of the material adverse impact that this could have on our business and
results of operations.

Risks Relating to Our Corporate Structure

Our ability to receive dividends and other payments from our subsidiaries may be restricted by commercial, statutory and legal restrictions, and thereby materially adversely affect our ability to
grow, fund investments, make acquisitions, pay dividends, repay or repurchase outstanding indebtedness and otherwise fund and conduct our business.

The ability of our subsidiaries to pay dividends or make other distributions to us is restricted by, among other things, the availability of funds and the terms of various credit arrangements entered into
by our subsidiaries, as well as statutory and other legal restrictions. In addition, although there are currently no foreign exchange control regulations which restrict the ability of our subsidiaries located in Taiwan to distribute dividends to us,
we cannot assure you that the relevant regulations will not be changed and that the ability of our subsidiaries to distribute dividends to us will not be restricted in the future. A Taiwan company is generally not permitted to distribute dividends
or to make any other distributions to shareholders for any year in which it did not have either earnings or retained earnings (excluding reserves). In addition, before distributing a dividend to shareholders following the end of a fiscal year, the
company must recover any past losses, pay all outstanding taxes and set aside 10% of its annual profit (less prior years losses and outstanding taxes) as a legal reserve until the accumulated legal reserve equals its paid-in capital, and may
set aside a special reserve.

In addition, PRC law requires that our PRC-incorporated subsidiary only distributes dividends
out of its profit, if any, as determined in accordance with PRC accounting standards and regulations. Under PRC law, it is also required to set aside at least 10% of its after-tax profit each year into its reserve fund until the accumulated legal
reserve amounts to 50% of its registered capital. PRC-incorporated companies are further required to maintain a bonus and welfare fund at percentages determined at their sole discretion. The reserve fund and the bonus and welfare fund are not
distributable as dividends. Moreover, a ROC-incorporated company is only able to declare dividends at its annual general meeting of shareholders, which cannot occur until after completion of its annual financial statements. Any limitation on
dividend payments by our subsidiaries could materially adversely affect our ability to grow, fund investments, make acquisitions, pay dividends, repay or repurchase outstanding indebtedness, and otherwise fund and conduct our business.

Baupost Group LLC/MA, our largest shareholder may have significant influence over our company and may cause us to take actions that may not be, or
refrain from taking actions that may be, in our best interest or the best interest of our other shareholders.

As of
March 31, 2015, Baupost Group LLC/MA owned 11.5% of our common shares, according to the 13F filed by Baupost Group LLC/MA on February 13, 2015. This shareholder, through its equity interests, may have significant influence over matters
submitted to our shareholders for approval and other corporate actions, such as:



| |  |  | election of directors;
| | - |  | ----------------------



| |  |  | timing and manner of dividend distributions;
| | - |  | --------------------------------------------



| |  |  | approval of contracts between us and the largest shareholder or its respective affiliates, which could involve conflicts of interest;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | open market purchase programs or other purchases of our common shares;
| | - |  | ----------------------------------------------------------------------



| |  |  | delay, defer or prevent a change in who controls us;
| | - |  | ----------------------------------------------------



| |  |  | discourage bids for our shares at a premium over the market price; and
| | - |  | ----------------------------------------------------------------------



| |  |  | adversely affect the market price of our common shares.
| | - |  | -------------------------------------------------------

Moreover, because large shareholders have potential power to direct or influence our corporate actions, we may be required to engage in transactions that may not be agreeable to our other shareholders or
that may not be in the best interest of our other shareholders.

Our ability to make further investments in ChipMOS Taiwan may be dependent on relevant stock exchanges
requirements or other regulatory approval requirements. If ChipMOS Taiwan is unable to receive the equity financing it requires, its ability to grow and fund its operations, and as a result our ability to grow and conduct our business, may be
materially adversely affected.

Even though trading on the Emerging Stock Board of Gre Tai Securities Market of
ChipMOS Taiwans shares under stock code 8150 commenced on April 19, 2013, ChipMOS Taiwan will continue to depend on its shareholders, ChipMOS Bermuda and Siliconware Precision, to meet its equity financing requirements prior
to consummation of its plan of listing on the TWSE. On January 28, 2014, the Review Committee of the TWSE approved the listing application of ChipMOS Taiwan to be listed on the TWSE. ChipMOS Taiwan subsequently became listed and commenced
trading on the main board of TWSE on April 11, 2014. See ChipMOS Taiwans ability to maintain its listing and trading status on the Taiwan Stock Exchange is dependent on factors outside of the Company or ChipMOS Taiwans
control and satisfaction of stock exchange requirements. ChipMOS Taiwan may not be able to overcome such factors that disrupt its trading status on the main board of Taiwan Stock Exchange or satisfy other eligibility requirements that may be
required of it in the future. and Item 7. Major Shareholders and Related Party TransactionsRelated Party Transactions. Any capital contribution by us to ChipMOS Taiwan may require the approval of the relevant stock exchange
or other ROC authorities. For example, any capital contribution by us to ChipMOS Taiwan will require the approval of the authorities of the Science Park Administration. We may not be able to obtain any such approval in the future in a timely manner,
or at all. If ChipMOS Taiwan is unable to receive the equity financing it requires, its ability to grow and fund its operations, and as a result ChipMOS Bermudas ability to grow and conduct our business, may be materially adversely affected.

ChipMOS Taiwans ability to maintain its listing and trading status on the Taiwan Stock Exchange is dependent on factors outside
of the Company or ChipMOS Taiwans control and satisfaction of stock exchange requirements. ChipMOS Taiwan may not be able to overcome such factors that disrupt its trading status on the main board of Taiwan Stock Exchange or satisfy other
eligibility requirements that may be required of it in the future.

ChipMOS Taiwan became listed and commenced trading
on the main board of TWSE on April 11, 2014. For a TWSE-listed company to continue trading on the main board of TWSE depends in part on market conditions and other factors that may not within the control of the Company or ChipMOS Taiwan. For
these reasons there can be no assurance that ChipMOS Taiwans shares will continue to be listed or traded on the TWSE.

Risks Relating
to Our Common Shares

Volatility in the price of our common shares may result in shareholder litigation that could in turn result in
substantial costs and a diversion of our managements attention and resources.

The financial markets in the
United States and other countries have experienced significant price and volume fluctuations, and market prices of technology companies have been and continue to be extremely volatile. Volatility in the price of our common shares may be caused by
factors outside of our control and may be unrelated or disproportionate to our results of operations. In the past, following periods of volatility in the market price of a public companys securities, shareholders have frequently instituted
securities class action litigation against that company. Litigation of this kind could result in substantial costs and a diversion of our managements attention and resources.

Certain provisions in our constitutive documents and in our severance agreements with our executive officers make the acquisition of us by another company more difficult and costly and therefore may
delay, defer or prevent a change of control.

Our bye-laws provide that our board of directors is divided into three
classes of directors, each class to be re-elected only once every three years. As a result, shareholders would not generally be able to replace a majority of the directors until after two annual general meetings. In addition, any extraordinary
corporate transaction such as a merger, amalgamation or consolidation, or a sale or transfer of all or substantially all of our assets cannot be done without the approval of shareholders representing 70% of the total voting rights of all
shareholders having the right to vote at such general meeting called to consider such extraordinary transaction. These provisions in our constitutive documents may increase the difficulty faced by a party which seeks to acquire control of our board
or to approve an extraordinary transaction.

In 2007, we entered into change in control severance agreements with certain
executive officers pursuant to which we agreed to pay certain severance payments if a change in control event (as defined in the change in control severance agreements) occurs and the employment of such executive officer is terminated by our company
other than for cause or by such executive officer for good reasons within two years following the occurrence of the change in control event. These agreements may increase the cost of a party seeking to effect a change in control of our company.

Future sales, pledge or issuance of common shares by us or our current shareholders could depress our
share price and you may suffer dilution.

Sales of substantial amounts of shares in the public market, the perception
that future sales may occur, or the pledge of a substantial portion of our common shares could depress the prevailing market price of our shares. As of March 31, 2015, we had approximately 29 million common shares issued and outstanding.
As of March 31, 2015, Baupost Group LLC/MA, our largest shareholder, owned 3,283,235 common shares, representing approximately 11.5% of our outstanding common shares. See Item 7. Major Shareholders and Related Party
TransactionsMajor Shareholders.

Mosel in the past decided to sell a significant portion of our common shares in
order to raise funds. In June 2006, Mosel sold 1,739,130 common shares through its wholly-owned subsidiary, Giant Haven, under a shelf registration statement which has since expired. In addition, in March 2007, we issued 3,043,749 common
shares pursuant to a share purchase and subscription agreement with ChipMOS Taiwan and Siliconware Precision, and we entered into a registration rights agreement in March 2007 with Siliconware Precision, pursuant to which we granted to Siliconware
Precision certain rights to require us to register these common shares for sale under the Securities Act. In July 2007, Mosel sold 2,030,316 common shares through Giant Haven Investment Limited (Giant Haven) to ProMOS Technologies
Inc. (ProMOS) and Powertech Technology Inc. (Powertech Technology) and we then granted Giant Haven, ProMOS and Powertech Technology certain rights to require us to register these common shares for sale under the Securities
Act. For a shareholder that is not our affiliate these shares may be resold pursuant to Rule 144 after lapse of the applicable holding period. In 2008, ProMOS failed to meet its payment obligations to ThaiLin. Subsequently in March 2009, ThaiLin
acquired 1,015,158 common shares from ProMOS pursuant to its enforcement of the collateral under a Stock Pledge Agreement between ThaiLin and ProMOS dated December 3, 2008. In November 2012, ThaiLin sold 2,000,000 common shares and Siliconware
Precision sold 800,000 common shares pursuant to a Secondary Offering. In May 2013, ThaiLin completed its sale of 380,506 of our common shares to Tokyo Seimitsu. In November 2013 and January 2014, ThaiLin sold 2,000,000 common shares and 2,093,705
common shares back to ChipMOS Bermuda, respectively. After the transactions, ThaiLin did not hold any of our common shares. In September 2014, Siliconware Precision sold 1,000,000 common shares back to ChipMOS Bermuda. From April 2012 to March 2014,
Mosel sold 2,267,270 common shares through its wholly-owned subsidiary, Giant Haven, under Rule 144. By the end of 2014, Mosel and Mosels wholly-owned subsidiary, Giant Haven did not hold any of our common shares. Furthermore, Siliconware
Precision may be able to sell, in any three-month period, that number of those ChipMOS common shares that Siliconware Precision owns, up to the greater of (i) one percent of our outstanding common shares or (ii) the average weekly trading
volume of our common shares as reported on the NASDAQ Capital Market during the four calendar weeks prior to filing a notice under Rule 144(h) for any such sales pursuant to Rule 144(e) under the Securities Act.

On September 14, 2007, ChipMOS Bermuda issued 151,031 common shares pursuant to a share exchange transaction with ChipMOS
Taiwan, under which ChipMOS Bermuda exchanged one common share for every 8.4 ChipMOS Taiwan shares then outstanding. Following the completion of the share exchange transaction, ChipMOS Taiwan became our wholly-owned subsidiary. In February 2010, we
agreed to sell 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision. In January 2011, the share purchase transaction was completed and we owned 84.2% of ChipMOS Taiwans outstanding shares as of December 31, 2011. On
April 16, 2013, as part of ChipMOS Taiwans listing plan on the TWSE, we completed the sale of 6.5 million outstanding ChipMOS Taiwan shares or 0.8% of the total number of ChipMOS Taiwans outstanding shares, at the price of
NT$15.0 per share to ChipMOS Taiwans underwriters for the TWSE listing plan and to certain others, including non-US employees of ChipMOS Taiwan. From September 2, 2013 to October 3, 2013, we sold 180 million shares or 21.4% of
the total number of ChipMOS Taiwans outstanding shares, at the price of NT$20.0 per shares to investors. After the completion of the aforesaid sales the Company held approximately 523 million ChipMOS Taiwan shares, representing 62.1% of
the total number of ChipMOS Taiwans outstanding shares. On April 9, 2014, ChipMOS Bermuda sold approximately 1.3 million ChipMOS Taiwan shares as green shoe option to market investors. ChipMOS Taiwan became listed and
commenced trading on the main board of TWSE on April 11, 2014. As of the date of this Annual Report on Form 20-F, we continue to own approximately 522 million ChipMOS Taiwan shares, representing 60.4% of ChipMOS Taiwans outstanding
shares without any green shoe option outstanding. See Risk Relating to Our Corporate StructureChipMOS Taiwans ability to maintain its listing and trading status on the Taiwan Stock Exchange is dependent on factors
outside of the Company or ChipMOS Taiwans control and satisfaction of stock exchange requirements. ChipMOS Taiwan may not be able to overcome such factors that disrupt its trading status on the main board of Taiwan Stock Exchange or satisfy
other eligibility requirements that may be required of it in the future for additional information on ChipMOS Taiwans listing plan. We plan to issue, from time to time, additional shares in connection with employee compensation and to
finance possible future capital expenditures, investments or acquisitions. See Item 6. Directors, Senior Management and EmployeesShare Option Plan and Share Appreciation Rights Plan for a discussion of the Share Option Plan that we
have adopted for the benefit of all of our directors, officers, employees and consultants. The issuance of additional shares may have a dilutive effect on other shareholders and may cause the price of our common shares to decrease.

In addition, the indictment relating to Mr. Hung-Chiu Hu alleges that embezzled funds were used in investments by PacMOS
Technologies Holdings Limited (PacMOS), which, as of March 31, 2015, owned 2.4% of our outstanding common shares. As a result, PacMOS may be ordered by relevant authorities to dispose of its investments made with any embezzled
funds, which may result in a sale of our shares by PacMOS. A sale of a significant number of our shares by PacMOS or our other current shareholders could depress our share price.

If the trading price of our common shares declines, we may face a
limited public market for our common shares and reduced availability of future debt or equity financing.

Companies
listed on the NASDAQ Stock Market (NASDAQ) are subject to delisting for, among other things, failure to maintain a minimum closing bid price of US$1.00 per share for 30 consecutive business days. We are in compliance with the NASDAQ
Listing Rules as of the date of this Annual Report on Form 20-F. We were not in compliance with the NASDAQ minimum bid price requirement from September 15, 2009 until May 5, 2010, when we regained compliance. During this time, we applied
for, and NASDAQ approved, the transfer of our listing from NASDAQ Global Select Market to NASDAQ Capital Market. If the bid price of our common stock falls below US$1.00 per share for 30 consecutive business days again in the future, we may be
subject to delisting. If our common shares are delisted from the NASDAQ Capital Market, our common shares would likely trade in the over-the-counter market, which could make selling our common shares more
difficult. Smaller quantities of shares would likely be bought and sold, transactions could be delayed, and security analysts coverage of us may be reduced. In addition, in the event our common shares are delisted, broker-dealers have certain
regulatory burdens imposed upon them, which may discourage broker-dealers from effecting transactions in our common shares. These factors could limit our common shares liquidity and result in lower prices and larger spreads in the bid and ask
prices for our common shares.

Future declines in our share price could also significantly impair our ability to raise
additional necessary capital through equity or debt financing, and could significantly increase ownership dilution to shareholders caused by our issuing equity in financing or other transactions. A general permission under the Exchange Control Act
1972 and the Exchange Control Regulation 1973 (as amended) (and other relevant legislations and regulations) of Bermuda has been given by the Bermuda Monetary Authority (the BMA) for the issue and transfer of our common shares to and
between non-residents of Bermuda for exchange control purposes, provided that our common shares remain listed on an appointed stock exchange (which includes listing on the NASDAQ Capital Market). In the event our common shares are no longer listed
on the NASDAQ Capital Market or another appointed stock exchange, specific consents of the BMA would be required for all issues and transfers of our shares, unless such issues and/or transfers fall under certain exemptions as provided by the BMA.

Pending merger with ThaiLin may or may not complete or achieve the expected synergy, efficiency and effectiveness.

On November 12, 2014, ChipMOS Taiwan made public announcement at Market Observation Post System, the official public disclosure
website for TWSE-listing companies in Taiwan, announcing ChipMOS Taiwans contemplated merger with ThaiLin, a Taiwan company which approximately 47.5% issued share capital is held by ChipMOS Taiwan (the Merger). The Company made the
corresponding announcement of the Merger at EDGAR on the same date. As a result of the Merger, pursuant to all of the terms and conditions of the Merger Agreement by and between ChipMOS Taiwan and ThaiLin, dated November 12, 2014 (the
Merger Agreement), ThaiLin will merge into ChipMOS Taiwan, which will hold 100% of the issued share capital of Modern Mind, which holds 100% interests of ChipMOS Shanghai. The Merger was approved by the board of directors of ChipMOS
Taiwan and ThaiLin on November 12, 2014, and approved by the shareholders of ChipMOS Taiwan and ThaiLin on December 30, 2014. As a result of Merger, ChipMOS Taiwan will become our 58.0% owned subsidiary and ChipMOS Shanghai will become an
indirectly wholly-owned subsidiary of ChipMOS Taiwan through ChipMOS Taiwans wholly-owned subsidiary, Modern Mind. The interests of ChipMOS Bermuda in Modern Mind and ChipMOS Shanghai will increase to 58.0%. The testing services provided by
ThaiLin will be continually provided by ChipMOS Taiwan. And, no effect of the Merger on our quality control, insurance coverage, tax credit and alternative minimum tax (AMT) expenses imposed under the ROC Alternative Minimum Tax Act
(AMT Act).

Completion of the Merger is expected to occur on June 17, 2015 and is further subject to the
satisfaction or waiver of the conditions set forth in the Merger Agreement and the receipt of approvals from relevant Republic of China governing authorities, including but not limited to the Fair Trade Commission, Financial Supervisory Commission,
TWSE, and Gre Tai Securities Market. The Company intends to work with all parties to satisfy conditions set forth in the Merger Agreement in order to complete the Merger.

Although we expect that completion of the Merger will occur as contemplated in the Merger Agreement, unforeseen events and occurrences may delay or prevent completion of the Merger, or may significantly
reduce the anticipated potential benefits to ChipMOS of the Merger. However, prior to the completion of the Merger, there might be situation such as event default continuing for 60 days without improvement by the default party that causes ChipMOS
Taiwan or ThaiLin to decide that the Merger should be abandoned and completion of the Merger is no longer desired. It could develop that the conditions precedent to the Merger are not satisfied or waived, which in turn could delay or prevent
completion of the Merger. Moreover, although we believe that the Merger will increase synergy, efficiency, and effectiveness of the Company and its subsidiaries, there can be no assurance that the expected synergy, efficiency, and effectiveness of
the Company and its subsidiaries will be realized after the completion of the Merger. In particular, if the industry change or our business decline could prevent these from being realized.

Below is a description of our principal consolidated subsidiaries:

ChipMOS TECHNOLOGIES INC. ChipMOS Taiwan was incorporated in Taiwan in July 1997 as a joint venture company of Mosel and
Siliconware Precision and with the participation of other investors. Its operations consist of the testing and assembly of semiconductors as well as gold bumping and memory module manufacturing. We acquired our interest in ChipMOS Taiwan by issuing
our common shares to ChipMOS Taiwans shareholders in exchange for their 70.3% shareholding in ChipMOS Taiwan in January 2001. In October 2001, ChipMOS Taiwan issued 6,911,732 common shares as employee bonuses. In December 2002, we issued
132,793 common shares in exchange for 5,633,442 ChipMOS Taiwan common shares held by these employees.

On March 27,
2007, we completed a share purchase and subscription transaction with ChipMOS Taiwan and Siliconware Precision, under which we and ChipMOS Taiwan purchased all of Siliconware Precisions equity interest in ChipMOS Taiwan, and Siliconware
Precision subscribed to 3,043,749 of our newly issued common shares through a private placement. As of March 31, 2007, we held 99.1% of the outstanding common shares of ChipMOS Taiwan. On September 14, 2007, we completed a share
exchange transaction with ChipMOS Taiwan pursuant to which we exchanged one common share for every 8.4 ChipMOS Taiwan shares. In connection with the share exchange transaction, ChipMOS Bermuda and ChipMOS Taiwan paid in the aggregate NT$53 million
in cash to purchase fractional shares and shares held by dissenting shareholders, and ChipMOS Bermuda issued 151,031 new common shares. Following the completion of the share exchange transaction, ChipMOS Taiwan became our wholly-owned
subsidiary. In February 2010, we agreed to sell 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision. The share purchase transaction was completed in January 2011. On April 16, 2013, as part of ChipMOS Taiwans
listing plan on the TWSE, we completed the sale of 6.5 million outstanding ChipMOS Taiwan shares or 0.8% of the total number of ChipMOS Taiwans outstanding shares, at the price of NT$15.0 per share to ChipMOS Taiwans underwriters
for the TWSE listing plan and to certain others, including non-US employees of ChipMOS Taiwan. From September 2, 2013 to October 3, 2013, we sold 180 million shares or 21.4% of the total number of ChipMOS Taiwans outstanding
shares, at the price of NT$20.0 per shares to investors. After the completion of the aforesaid sale, the Company held approximately 523 million ChipMOS Taiwan shares, representing 62.1% of the total number of ChipMOS Taiwans outstanding
shares. On April 9, 2014, ChipMOS Bermuda sold approximately 1.3 million ChipMOS Taiwan shares as green shoe option to market investors. ChipMOS Taiwan became listed and commenced trading on the main board of TWSE on
April 11, 2014. As of the date of this Annual Report on Form 20-F, we continue to own approximately 522 million ChipMOS Taiwan shares, representing 60.4% of ChipMOS Taiwans outstanding shares without any green shoe
option outstanding. See Item 3. Key InformationRisk FactorsRisk Relating to Our Corporate StructureChipMOS Taiwans ability to maintain its listing and trading status on the Taiwan Stock Exchange is dependent on factors
outside of the Company or ChipMOS Taiwans control and satisfaction of stock exchange requirements. ChipMOS Taiwan may not be able to overcome such factors that disrupt its trading status on the main board of Taiwan Stock Exchange or satisfy
other eligibility requirements that may be required of it in the future for additional information.

The share numbers
disclosed in the foregoing paragraph are adjusted to reflect the Companys 1-for-every-4 reverse stock split effective on January 21, 2011.

MODERN MIND TECHNOLOGY LIMITED and ChipMOS TECHNOLOGIES (Shanghai) LTD. Modern Mind was incorporated in the British Virgin Islands in January 2002. Modern Mind conducts its operations
through ChipMOS Shanghai, a wholly-owned subsidiary incorporated in Mainland China in June 2002. ChipMOS Shanghai is engaged in wafer testing and semiconductor assembly and testing. We acquired a 100% equity interest in Modern Mind on
December 12, 2002, and then transferred it to Jesper on December 31, 2002. In 2003, we acquired from Jesper a convertible note in the amount of US$37.5 million issued by Modern Mind that may be converted into a controlling equity interest
in Modern Mind at a conversion rate of one ordinary share of Modern Mind for every US$1.00 if the repayment is not made when due. In 2004, we restructured our control of ChipMOS Shanghai and our Mainland China operations. On July 29, 2004, we
replaced the US$37.5 million convertible note previously issued by Modern Mind in its entirety with a US$62.8 million demand note issued by Modern Mind, with the difference representing a US$25 million loan that we extended to Modern Mind from the
net proceeds of our July 2004 offering of common shares. In addition, we extended a loan in the aggregate amount of US$50 million to Modern Mind from the net proceeds of our November 2004 convertible debt offering in exchange for demand notes issued
by Modern Mind in the same aggregate amount (the MMT Notes). The MMT Notes were convertible at any time into common shares representing, immediately after the conversion, almost 100% of the then outstanding common shares of Modern Mind
at a conversion rate of US$1.00 for each common share of Modern Mind. Payment under the MMT Notes were fully and unconditionally guaranteed by Jesper and secured by a pledge agreement in respect of the entire equity interest in Modern Mind and
ChipMOS Shanghai. We obtained from Jesper an irrevocable option to acquire at any time the common shares of Modern Mind then owned by Jesper. Under an assignment and assumption agreement signed on April 22, 2011 (the MMT Assignment
Agreement), ChipMOS agreed to sell the MMT Notes to ThaiLin for a purchase price of approximately US$40 million subject to certain closing conditions. Post completion of MMT Assignment Agreement transaction, ThaiLin immediately converted the
MMT Notes into common shares of Modern Mind and purchased all of the remaining common shares of Modern Mind from Jesper, with Modern Mind becoming a wholly-owned subsidiary of ThaiLin. The MMT Assignment Agreement was completed on October 3,
2011.

reason at any time by giving 30 days prior written notice to ChipMOS Shanghai.

ThaiLin Semiconductor
Corp. ThaiLin was incorporated in Taiwan in May 1996, and is listed on the Gre Tai Securities Market in Taiwan. It is engaged in the provision of semiconductor testing services. ChipMOS Taiwan acquired a 41.8% interest in ThaiLin in December
2002. Under applicable accounting principles, ThaiLin was consolidated into our consolidated financial statements in 2003 because ChipMOS Taiwan was deemed to exert significant control over ThaiLin through common directors and management.

On March 4, 2008, ChipMOS Taiwan made a loan in an amount of NT$145 million bearing interest at a rate of 4.69% per
annum to Taiwan Kolin Co. Ltd., or Kolin, a major shareholder of ThaiLin, ChipMOS Taiwans 42.9% owned subsidiary. NT$15 million of this loan was repaid in 2008. The loan was secured by a pledge by Kolin of 11 million common shares of
ThaiLin. In 2013, the loan has been fully repaid and the subject pledge has been released accordingly. See Item 7. Major Shareholders and Related Party TransactionsRelated Party TransactionsThaiLin Semiconductor Corp.

As of March 31, 2015, ChipMOS Taiwan held a 47.5% interest in ThaiLin. Mr. Shih-Jye Cheng, our chairman and chief
executive officer and the director and chairman of ChipMOS Taiwan, is also a director of ThaiLin. In addition, four of the nine directors of ThaiLin are appointed by ChipMOS Taiwan.

Industry Background

We provide a broad range of back-end testing services, including engineering testing, wafer probing and final testing of memory and logic/mixed-signal semiconductors. We also offer a broad selection of
leadframe-based and organic substrate-based package assembly services for memory and logic/mixed-signal semiconductors. Our advanced leadframe-based packages include thin small outline packages, or TSOPs, and our advanced organic substrate-based
packages include fine-pitch ball grid array packages or fine-pitch BGA. In addition, we provide gold bumping, testing and assembly services for LCD and other flat-panel display driver semiconductors by employing TCP, COF and COG technologies.

Semiconductors tested and assembled by us are used in personal computers, graphics applications, such as game consoles and
personal digital assistants, or PDAs, communications equipment, such as cellular handsets, and consumer electronic products and display applications, such as flat-panel displays. In 2014, 23.2% of our revenue was derived from testing services for
memory and logic/mixed-signal semiconductors, 34.9% from assembly services for memory and logic/mixed-signal semiconductors, 23.5% from LCD and other flat-panel display driver semiconductor testing and assembly services and 18.4% from bumping
services for semiconductors.

Semiconductor Industry Trends

Growth in the semiconductor industry is largely driven by end-user demand for consumer electronics, communications equipment and
computers, for which semiconductors are critical components. The worldwide semiconductor industry has experienced peaks and troughs over the last decade, with a severe downturn at the end of 2000 that was followed by a modest recovery in late 2002.
Beginning in the fourth quarter of 2008, the semiconductor industry commenced another downturn that increased in unprecedented severity into the first quarter of 2009. The overall semiconductor industry commenced to recover from the downturn in the
second quarter of 2009 and the positive recovery trend continues through 2014.

Selected Key Semiconductor Markets

While a recovery trend in end-user demand for new and improved electronic products and applications continues, various
sectors of the semiconductor industry are in turn expected to benefit from a resumption in growth. These sectors include the memory semiconductor market, and the LCD and other flat-panel display driver semiconductor market.

Memory Semiconductor Market

The potential for memory market growth is linked to anticipated memory content increases in consumer electronics and PC applications (after such time as a recovery occurs in end-user demand for these) due
to increasing operating system requirements, increasing use of graphics in gaming and other applications, continued growth of broadband content and a transition to 64-bit PC architecture. The memory market is dominated by two segmentsDRAM and
flash memory. Potential growth in the DRAM market is expected to be driven by continued growth in both the commodity and niche DRAM market, as well as growth opportunities in mobile DRAM as memory requirements significantly increase for mobile
applications. Flash memory market potential growth is expected to be driven by increasing memory requirements for cellular handsets, digital cameras, digital audio/video, and other mobile applications.

LCD and Other Flat-Panel Display Driver Semiconductor Market

Flat-panel displays are used in applications such as PC monitors, notebook computers, television sets, cellular handsets and digital
cameras. The end-user demand for LCD and other flat-panel display driver semiconductor experienced a downturn in 2007 and 2008. The LCD driver market started to recover in the second quarter of 2009 and the positive recovery trend continued through
2014.

Logic/Mixed-Signal Semiconductor Market

The communications market is one of the main drivers of potential growth in the semiconductor industry. Logic/mixed-signal semiconductors, which are chips with analog functionality covering more than half
of the chip area, are largely used in the communications market. The increasing use of digital technology in communications equipment requires chips with both digital and analog functionality for applications such as modems, network routers,
switches, cable set-top boxes and cellular handsets. As the size and cost of cellular handsets and other communications-related devices have decreased, components have increased in complexity. Logic/mixed-signal semiconductors, such as LCD
controllers and DVD controllers, are also used in consumer electronic products.

|Circuit Design    |  | The design of a semiconductor is developed by laying out circuit patterns and interconnections.                                                                                                                                                                                                                                                                                                                                                                                                                                               
|                  | 
|Wafer Fabrication |  | Wafer fabrication begins with the generation of a photomask, a photographic negative onto which a circuit design pattern is etched or transferred by an electron beam or laser
beam writer. Each completed wafer contains many fabricated chips, each known as a die.                                                                                                                                                                                                                                                                         
|                  | 
|Wafer Probe       |  | Each individual die is then electrically tested, or probed, for defects. Dies that fail this test are discarded, or, in some cases, salvaged using laser repair.                                                                                                                                                                                                                                                                                                                                                                              
|                  | 
|Assembly          |  | The assembly of semiconductors serves to protect the die, facilitates its integration into electronic systems and enables the dissipation of heat. The process begins with the
dicing of the wafers into chips. Each die is affixed to a leadframe-based or organic substrate-based substrate. Then, electrical connections are formed, in many cases by connecting the terminals on the die to the inner leads of the package using
fine metal wires. Finally, each chip is encapsulated for protection, usually in a molded epoxy enclosure.
|                  | 
|Final Test        |  | Assembled semiconductors are tested to ensure that the device meets performance specifications. Testing takes place on specialized equipment using software customized for each
application. For memory semiconductors, this process also includes burn-in testing to screen out defective devices by applying very high temperatures and voltages onto the memory device.                                                                                                                                                                  

Outsourcing Trends in Semiconductor Manufacturing

Historically, integrated device manufacturers, or IDMs, designed, manufactured, tested and assembled semiconductors primarily at their own
facilities. In recent years, there has been a trend in the industry to outsource stages in the manufacturing process to reduce the high fixed costs resulting from the increasingly complex manufacturing process. Virtually every significant stage of
the manufacturing process can be outsourced. The independent semiconductor manufacturing services market currently consists of wafer fabrication and probing services and semiconductor testing and assembly services. Most of the worlds major
IDMs now use some independent semiconductor manufacturing services to maintain a strategic mix of internal and external manufacturing capacity. We believe that many of these IDMs are significantly reducing their investments in new semiconductor
testing and assembly facilities.

The availability of technologically advanced independent semiconductor manufacturing
services has also enabled the growth of fabless semiconductor companies that focus exclusively on semiconductor design and marketing and outsource their fabrication, testing and assembly requirements to independent companies.

##### Table of Contents

We believe the outsourcing of semiconductor manufacturing services, and in particular of
testing and assembly services, will increase for many reasons, including the following:

Significant Capital Expenditure
Requirements. Driven by increasingly sophisticated technological requirements, wafer fabrication, testing and assembly processes have become highly complex, requiring substantial investment in specialized equipment and facilities and
sophisticated engineering and manufacturing expertise. In addition, product life cycles have been shortening, magnifying the need to continually upgrade or replace manufacturing, testing and assembly equipment to accommodate new products. As a
result, new investments in in-house fabrication, testing and assembly facilities are becoming less desirable for IDMs because of the high investment costs, as well as difficulties in achieving sufficient economies of scale and utilization rates to
be competitive with the independent service providers. Independent foundry, testing and assembly companies, on the other hand, are able to realize the benefits of specialization and achieve economies of scale by providing services to a large base of
customers across a wide range of products. This enables them to reduce costs and shorten production cycles through high capacity utilization and process expertise.

Increasing Focus on Core Competencies. As the costs of semiconductor manufacturing facilities increase, semiconductor companies are expected to further outsource their wafer fabrication, testing
and assembly requirements to focus their resources on core competencies, such as semiconductor design and marketing.

Time-to-Market Pressure. Increasingly short product life cycles have amplified time-to-market pressure for semiconductor
companies, leading them to rely increasingly on independent companies as a key source for effective wafer fabrication, testing and assembly services.

Semiconductor Testing and Assembly Services Industry

Growth in the
semiconductor testing and assembly services industry is driven by increased outsourcing of the various stages of the semiconductor manufacturing process by IDMs and fabless semiconductor companies.

The Semiconductor Industry and Conditions of Outsourcing in Taiwan and Mainland China

Taiwan is one of the worlds leading locations for outsourced semiconductor manufacturing. The semiconductor industry in Taiwan has
developed such that the various stages of the semiconductor manufacturing process have been disaggregated, thus allowing for specialization. The disaggregation of the semiconductor manufacturing process in Taiwan permits these semiconductor
manufacturing service providers to focus on particular parts of the production process, develop economies of scale, maintain higher capacity utilization rates and remain flexible in responding to customer needs by lowering time-to-market pressure
faced by semiconductor companies. There are several leading service providers in Taiwan, each of which offers substantial capacity, high-quality manufacturing, leading semiconductor wafer fabrication, test, assembly and process technologies, and a
full range of services. These service providers have access to an educated labor pool and a large number of engineers suitable for sophisticated manufacturing industries. As a result, many of the worlds leading semiconductor companies
outsource some or all of their semiconductor manufacturing needs to Taiwans semiconductor manufacturing service providers and take advantage of the close proximity among facilities. In addition, companies located in Taiwan are very active in
the design and manufacture of electronic systems, which has created significant local demand for semiconductor devices.

Mainland China has emerged as a similarly attractive location for outsourced semiconductor manufacturing. Mainland China is an attractive
manufacturing location for electronic products because companies can take advantage of a well-educated yet low-cost labor force, cost savings due to tax benefits and a large domestic market. These factors have driven increased relocation of much of
the electronics industry manufacturing and supply chain to Mainland China. An increasing number of global electronic systems manufacturers and contract manufacturers are relocating or have relocated production facilities to Mainland China. We
believe that these electronic product manufacturers and contract manufacturers will source an increasing portion of their demand for semiconductors from semiconductor suppliers located in Mainland China in order to reduce production cycle times,
decrease costs, simplify supply chain logistics and meet local content requirements. In line with this trend, we have in recent years expanded our operations in Mainland China.

Our Strategy

Our goal is to reinforce our position as a leading
independent provider of semiconductor testing and assembly services, concentrating principally on memory, logic/mixed-signal and LCD and other flat-panel display driver semiconductors. The principal components of our business strategy are set forth
below.

Focus on Providing Our Services to Potential Growth Segments of the Semiconductor Industry.

We intend to continue our focus on developing and providing advanced testing and assembly services for potential growth segments of the
semiconductor industry, such as memory, logic/mixed-signal, LCD and other flat-panel display driver semiconductors and bumping services. We believe that our investments in equipment and research and development in some of these areas allow us to
offer a differentiated service from our competition. In order to benefit from the expected resumption of growth in these segments, we intend to continue to invest in capacity to meet the testing and assembly requirements of these key semiconductor
market segments.

Continue to Invest in the Research and Development of Advanced Testing and Assembly
Technologies.

Critical to our business growth is the continuation to expand our capabilities in testing and assembly
to provide better service to our customers. We typically focus on advanced technologies that consist of greater potentials to generate higher margins. For example, we conducted new product introductions and on an on-going basis continue to expand
our capabilities in fine-pitch wafer bumping, multi-chip package (MCP), flip chip package, and high speed testing and assembly of fine-pitch COFs. We have also introduced low cost metal composite bump (MCB) products based on our proprietary Cu
plating technology to service flat-panel display market and expand offerings to other business regions. We continue to maintain close working relationships with local and overseas research institutions and universities to keep abreast with leading
edge technologies and broaden the scope of applications.

In 2015 we expect to focus our research and development efforts in
the following areas:



| |  |  | development of advanced assembly technologies in WLCSP, MEMS and flip chip products for memory devices and mixed signal products;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | expand fine-pitch Au and Cu bumping technology for 300mm products;
| | - |  | ------------------------------------------------------------------



| |  |  | expand fine-pitch test capabilities for advanced LCD drivers;
| | - |  | -------------------------------------------------------------



| |  |  | carry out in-process improvement to improve manufacturing yields and shorten turnaround time;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | develop new software conversion programs to increase the capabilities of our testers; and
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | continue to focus on delivering environmentally friendly assembly services by eliminating the lead and halogen elements from the materials.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------

In 2014, we spent approximately 3.1% of our revenue on research and development. We will continue to invest
our resources to recruit and retain experienced research and development personnel. As of March 31, 2015, our research and development team comprised 390 persons.

Build on Our Strong Presence in Taiwan and Expand Our Operations Outside Taiwan.

We intend to build on our strong presence in key centers of semiconductor and electronics manufacturing to grow our business. Currently, most of our operations are in Taiwan, one of the worlds
leading locations for outsourced semiconductor manufacturing. This presence provides us with several advantages. Firstly, our proximity to other semiconductor companies is attractive to customers who wish to outsource various stages of the
semiconductor manufacturing process. Secondly, our proximity to many of our suppliers, customers and the end-users of our customers products enables us to be involved in the early stages of the semiconductor design process, enhances our
ability to quickly respond to our customers changing requirements and shortens our customers time-to-market. Thirdly, we have access to an educated labor pool and a large number of engineers who are able to work closely with our
customers and other providers of semiconductor manufacturing services.

As with our operations in Taiwan, we intend to
similarly benefit from our operations in Mainland China. We intend to invest in and expand our operations in Mainland China, increasing our testing and assembly services for memory and logic/mixed-signal semiconductors.

Depending on customers demands, market conditions and other relevant considerations, we may from time to time look into other
opportunities to expand our operations outside Taiwan.

Expand Our Offering of Vertically Integrated Services.

We believe that one of our competitive strengths is our ability to provide vertically integrated services to our
customers. Vertically integrated services consist of the integrated testing, assembly and direct shipment of semiconductors to end-users designated by our customers. Providing vertically integrated services enables us to shorten lead times for our
customers. As time-to-market and cost increasingly become sources of competitive advantage for our customers, they increasingly value our ability to provide them with comprehensive back-end services.

Through ChipMOS Taiwan, ThaiLin and ChipMOS Shanghai, we are able to offer vertically integrated services for a broad range of products,
including memory, logic/mixed-signal and LCD and other flat-panel display driver semiconductors. We believe that these affiliations, which offer complementary technologies, products and services as well as additional capacity, will continue to
enhance our own development and expansion efforts into new and potential growth markets. We intend to establish new alliances with leading companies and, if suitable opportunities arise, engage in merger and acquisition activities that will further
expand the services we can provide.

Focus on Increasing Sales through Long-Term Agreements with Key Customers as well as
Business with Smaller Customers.

From time to time, we strategically agree to commit a portion of our testing and
assembly capacity to certain of our customers. We intend to continue focus on increasing sales to key customers through long-term capacity agreements. The customers with which we currently have long-term agreements include a reputable memory
customer based in the US. See  Customers below for a more detailed discussion of these long-term agreements.

Global market and economic conditions have been unprecedented and challenging with tight credit conditions and recession in most major
economies since 2008 continuing into 2014. Beginning in 2008, we also resumed our focus on our business with smaller customers or customers who do not place orders on a regular basis. We believe that the dual focused strategy will assist us to be
better prepared for the current economic volatility and ensure maximum utilization rate of our capacity and help us to develop closer relationships with all types of our customers.

| |  |  | Reliability Analysis. Reliability analysis is designed to assess the long-term reliability of the semiconductor and its suitability of use for
its intended applications. Reliability testing may include operating-life evaluation, during which the semiconductor is subjected to high temperature and voltage tests.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Failure Analysis.If the prototype semiconductor does not perform to specifications during either the electrical validation or reliability
analysis process, failure analysis is performed to determine the reasons for the failure. As part of this analysis, the prototype semiconductor may be subjected to a variety of tests, including electron beam probing and electrical testing.

Wafer Probing. Wafer probing is the process stage immediately before the assembly of semiconductors
and involves visual inspection and the electrical testing of the processed wafer to ensure that it meets our customers specifications. Wafer probing employs sophisticated design and manufacturing technologies to connect the terminals of each
chip for testing. Defective chips are marked on the surface or memorized in an electronic file, known as a mapping file, to facilitate subsequent process.

Laser Repairing. This is a unique process in testing operation for memory products. In laser repairing, specific poly or metal fuses are blown after wafer probing to enable a spare row or column of
a memory cell to replace a defective memory cell.

After assembly, we perform the following testing services:

Burn-In Testing. This process screens out unreliable products using high temperature, high voltage and prolonged stresses
environment to ensure that finished products will survive a long period of end-user service. This process is used only for memory products.

Top Marking . By using either a laser marker or an ink marker, we mark products according to our customers specification, including the logo, part number, date code and lot number

Final Testing. Assembled semiconductors are tested to ensure that the devices meet performance specifications. Tests are conducted
using specialized equipment with software customized for each application in different temperature conditions ranging from minus 45 degrees celsius to 110 degrees celsius. One of the tests includes speed testing to classify the parts into different
speed grades.

Final Inspection and Packing. Final inspection involves visual or auto-inspection of the devices to
check any bent leads, ball damage, inaccurate markings or other package defects. Packing involves dry packing, package-in-tray, packing-in-tube and tape and reel. Dry pack involves heating semiconductors in a tray at 125 to 150 degrees celsius for
about two hours to remove the moisture before the semiconductors are vacuum-sealed in an aluminum bag. Packing-in-tube involves packing the semiconductors in anti-static tubes for shipment. Tape and reel pack involves transferring semiconductors
from a tray or tube onto an anti-static embossed tape and rolling the tape onto a reel for shipment to customers.

Assembly

Our assembly services generally involve the following steps:



|                       |  |

##### Table of Contents

We offer a broad range of package formats designed to provide our customers with a broad
array of assembly services. The assembly services we offer customers are leadframe-based packages, which include thin small outline packages, and organic substrate-based packages, including fine-pitch BGA.

The differentiating characteristics of these packages include:



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



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



| |  |  | the electrical performance and requirements of the package; and
| | - |  | ---------------------------------------------------------------



| |  |  | the heat dissipation requirements of the package.
| | - |  | -------------------------------------------------

As new applications for semiconductor devices require smaller components, the size of packages has also decreased. In leading-edge packages, the size of the package is reduced to just slightly larger than
the size of the individual chip itself in a process known as chip scale packaging.

As semiconductor devices increase in
complexity, the number of electrical connections required also increases. Leadframe-based products have electrical connections from the semiconductor device to the electronic product through leads on the perimeter of the package. Organic
substrate-based products have solder balls on the bottom of the package, which create the electrical connections with the product and can support large numbers of electrical connections.

Leadframe-Based Packages. These are generally considered the most widely used package category. Each package consists of a
semiconductor chip encapsulated in a plastic molding compound with metal leads on the perimeter. This design has evolved from a design plugging the leads into holes on the circuit board to a design soldering the leads to the surface of the circuit
board.

The following diagram presents the basic components of a standard leadframe-based package for memory semiconductors:



LOGO

To address the market for miniaturization of portable electronic products, we are currently developing
and will continue to develop increasingly smaller versions of leadframe-based packages to keep pace with continually shrinking semiconductor device sizes. Our advanced leadframe-based packages generally are thinner and smaller, have more leads and
have advanced thermal and electrical characteristics when compared to traditional packages. As a result of our continual product development, we offer leadframe-based packages with a wide range of lead counts and sizes to satisfy our customers
requirements.

Organic Substrate-based Packages. As the number of leads surrounding a traditional leadframe-based
package increases, the leads must be placed closer together to reduce the size of the package. The close proximity of one lead to another can create electrical shorting problems and requires the development of increasingly sophisticated and
expensive techniques to accommodate the high number of leads on the circuit boards.

The BGA format solves this problem by effectively creating external terminals on the bottom
of the package in the form of small bumps or balls. These balls are evenly distributed across the entire bottom surface of the package, allowing greater pitch between the individual terminals. The ball grid array configuration enables high-pin count
devices to be manufactured less expensively with less delicate handling at installation.

Our organic substrate-based packages
employ a fine-pitch BGA design, which uses a plastic or tape laminate rather than a leadframe and places the electrical connections, or leads, on the bottom of the package rather than around the perimeter. The fine-pitch BGA format was developed to
address the need for the smaller footprints required by advanced memory devices. Benefits of ball grid array assembly over leadframe-based assembly include:



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



| |  |  | smaller footprint on a printed circuit board;
| | - |  | ---------------------------------------------



| |  |  | better electrical signal integrity; and

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

Wafer Level CSP



LOGO

Wafer-level CSP (WL CSP) is the technology of packaging an integrated circuit at wafer level. WL CSP is
essentially a true chip scale package (CSP) technology, since the resulting package is practically of the same size as the die. WL CSP has the ability to enable true integration of wafer fab, packaging, test, and burn-in at wafer level in order to
streamline the manufacturing process undergone by a device start from silicon wafer to customer shipment.

Most other kinds of
packaging does wafer dicing first, and then puts the individual die in a plastic package and attaches the solder bumps. WL CSP involves the RDL, wafer solder bumping, while still in the wafer, and then wafer dicing. Benefits of WL CSP compare to
general CSP package assembly include:



| |  |  | ultimate smaller package size;
| | - |  | ------------------------------



| |  |  | smaller footprint on a printed circuit board;
| | - |  | ---------------------------------------------



| |  |  | very short circuit connection; and

FC CSP



LOGO

Flip-chip chip scale package (FC CSP) construction utilizes the flip chip bumping (with solder bump or
Cu pillar bump) interconnection technology to replace the standard wirebond interconnect. It allows for a smaller form factor due to wire loop reduction and area array bumping. FC CSP includes the substrate or leadframe type solution making an
attractive option for advanced CSP application when electrical performance is a critical factor.



| |  |  | Excellent electrical performance, very low interconnect parasitics and inductance compare to wirebond type.
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | High electrical current endurance (Cu pillar bump), ideal for high power solution.
| | - |  | ----------------------------------------------------------------------------------



| |  |  | Smaller package form factor by reducing the wire loop height and wire span compared to conventional wirebond package.

LCD and Other Flat-Panel Display Driver Semiconductors and Gold Bumping

We also offer testing and assembly services for LCD and other flat-panel display driver semiconductors. We employ TCP,
COF and COG technologies for testing and assembling LCD and other flat-panel display driver semiconductors. In addition, we offer gold bumping services to our customers.

Tape Carrier Package (TCP) Technology

TCPs offer a high number of
inputs and outputs, a thin package profile and a smaller footprint on the circuit board, without compromising performance. Key package features include surface mount technology design, fine-pitch tape format and slide carrier handling. Because of
their flexibility and high number of inputs and outputs, TCPs are primarily employed either for STN-LCD or TFT-LCD driver semiconductors.

Testing of TCPs. We conduct full function testing of LCD and other flat-panel display driver semiconductors with a specially designed probe handler to ensure reliable contact to the test pads on
the TCP tape. We can test STN-LCD or TFT-LCD driver semiconductors with frequencies of up to 750 MHz and at voltages up to 40V. The test is performed in a temperature-controlled environment with the device in tape form. The assembled and tested LCD
and other flat-panel display driver semiconductors in tape form are packed between spacer tapes together with a desiccant in an aluminum bag to avoid contact during shipment.

Assembly of TCPs. TCPs use a tape-automated bonding process to connect die and tape. The printed circuit tape is shipped with a reel. The reel is then placed onto an inner lead bonder, where the
LCD or other flat-panel display driver semiconductor is configured onto the printed circuit tape. The resulting TCP component consists of the device interconnected to a three-layer tape, which includes a polyimide carrier film, an epoxy-based
adhesive layer and a metal layer. The tape metallization area of the interconnections is tin plated over a metal layer. The silicon chip and inner lead area is encapsulated with a high temperature thermosetting polymer after inner lead bonding. The
back face of the chip is left un-sealed for thermal connection to the printed circuit board.

For the limitation of inner lead
pitch (>41um) with this kind of package, the volume of TCP nowadays has been trending down to ~1% of total demand.

The
following diagram presents the basic components of a TCP:



LOGO

Chip-on-Film (COF) Technology

In 2001, we commenced testing and assembly services using COF technology. We have developed this proprietary technology from our existing TCP technology, and it has been widely accepted by our customers.
The primary use of the COF module is to replace TCP in certain applications.

COF technology provides several additional
advantages. For example, COF is able to meet the size, weight and higher resolution requirements in electronic products, such as flat-panel displays. This is because of its structural design, including an adhesive-free two-layer tape that is highly
flexible, bending strength and its capacity to receive finer patterning pitch.

COF package has been using for large-size and
high-resolution panel display nowadays, referring to the trend of the last several years, the avg. inner lead pitch of COF package went down to 25um with about 50% of market share. 22 um inner lead pitch of COF package has been released to mass

Chip-on-Glass (COG) Technology

COG technology is an electronic assembly technology that is used increasingly in assembling LCD and other flat-panel display driver
semiconductors for communications equipment. Compared to the traditional bonding process for TCP or COF, the new COG technology requires lower bonding temperature. In addition, the COG technology reduces assembly cost as it does not use tapes for
interconnection between the LCD panel and the printed circuit board. The major application of COG products is on TFT-LCD display of smart phone market, it integrates source, gate driver of TFT-LCD driver IC and Timing Controller IC into one chip, so
the output channel is larger than TCP or COF products.

The COG assembly technology involves the following steps:

##### Table of Contents

Gold bumping technology, which can be used in TCP, COF and COG technologies, is a necessary
interconnection technology for LCD and other flat-panel display driver semiconductors. Most gold bumping services are performed on eight or twelve-inches wafers. Gold bumping technology provides the best solution for fine-pitch chips and is able to
meet the highly efficient production requirement for LCD and other flat-panel display driver semiconductors or other chips that require thin packaging profiles. In addition to the gold bumping, we also offer the WLCSP, Cu RDL and Cu pillar service
which can be applied for FC CSP and/or QFN package. The product scope includes but is not limited to flash, power devices and MEMS .

The gold bumping fabrication process uses thin film metal deposition, photolithography and electrical plating technologies. A series of barrier and seed metal layers are deposited over the surface of the
wafer. A layer of thick photoresist material is spin-coated over these barrier and seed layers. A photomask is used to pattern the locations over each of the bond pads that will be bumped. UV exposure and developing processes open the photoresist
material, which defines the bump shape. The gold bump is then electroplated over the pad and the deposited barrier metal layers. Once the plating is complete, a series of etching steps are used to remove the photoresist material and the metal layers
that are covering the rest of the wafer. The gold bump protects the underlying materials from being etched. The gold bumped wafers will go through an annealing furnace to soften the gold bumps to fit the hardness requirement of TCP, COF and COG
assembly processes.

Other Services

Drop Shipment

We offer drop shipment of semiconductors directly to
end-users designated by our customers. We provide drop shipment services, including assembly in customer-approved and branded boxes, to a majority of our testing and assembly customers. Since drop shipment eliminates the additional step of
inspection by the customer prior to shipment to end-users, quality of service is a key to successful drop shipment service. We believe that our ability to successfully execute our full range of services, including drop shipment services, is an
important factor in maintaining existing customers as well as attracting new customers.

Software Development,
Conversion and Optimization Program

We work closely with our customers to provide sophisticated software engineering
services, including test program development, conversion and optimization, and related hardware design. Generally, testing requires customized testing software and related hardware to be developed for each particular product. Software is often
initially provided by the customer and then converted by us at our facilities for use on one or more of our testing machines and contains varying functionality depending on the specified testing procedures. Once a conversion test program has been
developed, we perform correlation and trial tests on the semiconductors.

Customer feedback on the test results enables us to
adjust the conversion test programs prior to actual testing. We also typically assist our customers in collecting and analyzing the test results and recommends engineering solutions to improve their design and production process.

The majority of our customers purchase our services through purchase orders and provide us
three-month non-binding rolling forecasts on a monthly basis. The price for our services is typically agreed upon at the time when a purchase order is placed.

In 2006 and 2007, we strategically entered into or extended certain long-term agreements with some of our key customers, including a reputable memory customer based in the US, under which we reserved
capacity for the customers primarily and the customer committed to place orders in the amount of the reserved capacity (which is subject in certain cases to reduction by the customer).

Pursuant to the long-term service agreement we have entered into with ProMOS in July 2007, ProMOS agreed to provide us with six month
rolling forecast on testing and assembly service orders to be placed to us, and ProMOS guarantees that such orders will represent no less than certain percentage of ProMOS total production volume of these products (excluding OEM products). In
January 2008, at the request of ProMOS, we agreed to permit ProMOS to defer payment of aggregate service fees of NT$450 million to February 15, 2009. The deferred service fees, bore an interest at a rate of 4.69% per annum, was recorded as
long-term accounts receivables as of December 31, 2007, and were paid in full by ProMOS in March and April 2008. In March 2008, ProMOS failed to place orders in the amount of the reserved capacity and failed to meet its payment obligations
under the long-term service agreement. In November 2008, we entered into a revised subcontracting contract with ProMOS by requiring ProMOS to provide wafers with a value of 80% of the subcontracting fee as collateral. In May 2009, a further revised
subcontracting contract was entered into by and between us and ProMOS under which ProMOS provided us with wafer as pledge and Work-In-Process, or WIP and existing finished goods as lien material. Part of ProMOS receivables will be recovered
through sales of the pledged wafer and lien material back to ProMOS with a discount to market price, and the remaining outstanding accounts receivables will be secured by equipment mortgage under the same contract arrangement. Effective March 2009,
we started to request prepayment from ProMOS. As of December 31, 2009, other receivables from ProMOS amounted to NT$409 million and 100% allowance was made by ChipMOS Taiwan. NT$7 million was received by April 2010. Under the amended
subcontracting contract, ProMOS paid ChipMOS Taiwan NT$200 million in May 2010. The remaining NT$202 million was paid in nine monthly installments with final installment payment ended on March 15, 2011. As of December 31, 2010, ChipMOS
Taiwan received NT$336 million and the related allowance of NT$409 million was reversed to other non-operating income. In March 2011, all payments have been received. The collection term was revised to 30 days upon delivery in May 2010, to 45 days
upon delivery in October 2010 and to the current term of advance payment prior to delivery from ProMOS in June 2011.

As of December 31, 2009, other receivables from ProMOS amounted to NT$55 million and
100% allowance was made by ThaiLin. In June 2010, ThaiLin agreed a settlement with ProMOS in the amount of NT$24 million and it was collected during the same year. The allowance of NT$24 million was reversed to other non-operating income. Commencing
in June 2010, the collection term was revised to become 30 days upon delivery. In January 2011, the collection term was revised to 45 days after delivery and it was further revised to request advance payments from ProMOS in June 2011.

Pursuant to the long-term service agreement we have entered into with Spansion in September 2005, Spansion agreed to provide us with six
month rolling forecast on testing and assembly service orders to be placed to us. In January 2009, Spansion defaulted on its payment obligations under the long-term service agreement and we subsequently terminated the long-term service agreement
with Spansion on February 19, 2009. Our service fee receivable from Spansion in connection with its default amounted to NT$1,539 million. On March 1, 2009, Spansion filed for a voluntary petition for reorganization under Chapter 11 of the
U.S. Bankruptcy Code. Subsequent to such filing, on March 16, 2009, ChipMOS Taiwan was elected as the co-chairman of the Unsecured Creditor Committee to represent unsecured creditors in Spansions efforts to reorganize its debts under
Chapter 11 petition. In early January 2010, ChipMOS Taiwan resigned as a member of the Unsecured Creditor Committee.

On
January 25, 2010, ChipMOS Taiwan entered into a definitive Transfer of Claim Agreement to sell to Citigroup the general unsecured claim reflected in the proof of claim against Spansion Inc., Spansion Technology LLC, Spansion LLC, Spansion
International Inc. and Cerium Laboratories LLC (collectively, Spansion) filed by ChipMOS Taiwan in U.S. Bankruptcy Court. The claim that is the subject of the Transfer of Claim Agreement includes accounts receivable for testing and
assembly services provided to Spansion in the amount of approximately US$66 million to US$70 million (the Undisputed Claim). ChipMOS Taiwan received the purchase price for the Undisputed Claim of NT$1,118 million in February 2010 from
Citigroup. The Transfer of Claim Agreement also includes the sale of breach of contract and liquidated damages rights against Spansion in the amount of approximately US$234 million (the Damages Claim). The purchase price for the Damages
Claim was determined based on a purchase rate of 50.2% multiplied by the portion of the Damages Claim that was allowed by a final adjudication of the U.S. Bankruptcy Court and to the extent that the Court allows this claim. In furtherance of the
Transfer of Claim Agreement, the Company also has entered into an agreement to subscribe for, purchase and transfer to Citigroup rights offering shares to be issued by Spansion according to the Second Amended Joint Plan of Reorganization filed in
U.S. Bankruptcy Court. This agreement provided that Citigroup will pay to the Company the amount calculated based on the purchase price of the rights offering shares. On October 4, 2010, ChipMOS Taiwan entered into a settlement agreement with
Spansion LLC for the general unsecured claim on breach of contract and liquidated damages rights reflected in the proof of claim, Claim No. 5, against Spansion Inc., Spansion Technology LLC, Spansion LLC, Spansion International Inc. and Cerium
Laboratories LLC filed by ChipMOS Taiwan in the U.S. Bankruptcy Court. In October 2010, the Company has received payment of NT$2,118 million for the Transfer of Claim Agreement with Citigroup.

On April 22, 2010, the Company announced that Spansion LLC and ChipMOS Taiwan entered into a two-year wafer sort services agreement,
utilizing the V5400 test platform, making ChipMOS Taiwan Spansions exclusive wafer sort subcontractor, except for any sort equipment operated by Spansion LLC or currently located at Spansion Japan Limited. The wafer sort services agreement
became effective upon the effective date of Spansions confirmed plan of reorganization. The U.S. Bankruptcy Court confirmed Spansions Second Amended Plan of Reorganization on April 16, 2010. The effective date of Spansions
plan of reorganization is May 10, 2010. The wafer sort services agreement became effective on May 10, 2010 and has since been renewed twice for expiring in 2016.

Beginning in 2008, we also resumed a focus on our business with smaller customers and customers who do not place orders on a regular basis.

The following table sets forth, for the periods indicated, the percentage breakdown of our revenue, categorized by geographic region
based on the jurisdiction in which each customer is headquartered.

Qualification and Correlation by Customers

Our customers generally require that our facilities undergo a stringent qualification process during which the customer
evaluates our operations, production processes and product reliability, including engineering, delivery control and testing capabilities. The qualification process typically takes up to eight weeks, or longer, depending on the requirements of the
customer. For test qualification, after we have been qualified by a customer and before the customer delivers semiconductors 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 and Marketing

We maintain sales and marketing offices in Taiwan, Mainland China and the United States. Our sales and marketing strategy is to focus on memory semiconductors in Taiwan, Japan, Korea and the United
States, logic/mixed-signal semiconductors in Taiwan, Japan and the United States, LCD and other flat-panel display driver semiconductors in Japan, Taiwan, Hong Kong and Mainland China. As of March 31, 2015, our sales and marketing efforts were
primarily carried out by teams of sales professionals, application engineers and technicians, totaling 39 staff members. Each of these teams focuses on specific customers and/or geographic regions. As part of our emphasis on customer service, these
teams:



| |  |  | actively participate in the design process at the customers facilities;
| | - |  | ------------------------------------------------------------------------



| |  |  | resolve customer testing and assembly issues; and
| | - |  | -------------------------------------------------



| |  |  | promote timely and individualized resolutions to customers issues.
| | - |  | -------------------------------------------------------------------

We conduct marketing research through our in-house customer service personnel and through our relationships with our customers and
suppliers to keep abreast of market trends and developments. Furthermore, we do product and system bench marking analyses to understand the application and assembly technology evolution, such as analysis on mobile handsets and CD-/DVD-ROM players.
In addition, we regularly collect data from different segments of the semiconductor industry and, when possible, we work closely with our customers to design and develop testing and assembly services 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.

We have appointed a non-exclusive sales agent for promoting our services for memory semiconductors in the United States, Japan and Korea. Our sales agent helps us promote and market our services, maintain
relations with our existing and potential customers and communicate with our customers on quality, specific requirements and delivery issues. We generally pay our sales agent a commission of 1.0% to 3.5% of our revenue from services for memory
semiconductors in the United States, Japan and Korea. In 2013 and 2014, we paid approximately NT$9 million and NT$22 million (US$696 thousand), respectively, in commissions to our sales agent

Research and Development

To maintain our competitive edge for continued
business growth, we continue our focus of our investment in new technology research and development. In 2013 and 2014, we spent approximately NT$564 million, or 3% and NT$679 million (US$21 million), or 3%, respectively, of our revenue on research
and development. We intend to sustain these efforts.

Our research and development efforts have been focused primarily on new
technology instruction, improving efficiency and production yields of our testing and assembly services. From time to time, we jointly develop new technologies with local and international research institutions and universities. In testing area, our
research and development efforts focused particularly on high speed probing, fine pitch probing capability and wafer level burn-in technology. Our projects include:



| |  |  | Grew wafer level BIST testing capability;
| | - |  | -----------------------------------------



| |  |  | Developed one touchdown full contact testing capability for 200mm and 300mm wafers;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | Ramped up high frequency testing capability for LCDD;
| | - |  | -----------------------------------------------------



| |  |  | Built up fine pitch testing capability for 12um bump pitch products; and
| | - |  | ------------------------------------------------------------------------



| |  |  | Developing centralized server test control system.
| | - |  | --------------------------------------------------

For new product and product enhancement work in 2014, our work concentrates on three key development programs: WLCSP, MEMS and flip chip
technology. In the bumping area, we completed customer qualification of 300mm wafer Au bumping process in 2012 and started volume production in Q4, 2012. Development of Cu plating enables the entry of WLCSP, RDL and flip chip market. Turnkey
services of WLCSP and flip chip QFN have been implemented for mass production in 2013 based on the successful technology developments. In 2012, we also initiated both 200mm and 300mm Cu pillar bumping engineering work and, related packaging
technologies are being developed for mixed-signal and memory products in 2013.

In 2013, in-process engineering advancement
allowed us to extend our wirebond technology to service MEMS products. To further achieve cost reduction, alloy wire and 0.6 mil Au wirebond processes were also developed. In 2014, we will continue to work on improvements of wafer thinning and
polishing operations facilitate the expansion of multi-chip NAND packages offerings. Capability of handling miniature molded packages has been extended to 1x1 mm size and various improvements will also be made in production equipment to enhance
throughput and efficiency.

As of March 31, 2015, we employed 390 employees in our research and development activities.
In addition, other management and operational personnel are also involved in research and development activities but are not separately identified as research and development professionals.

We maintain laboratory facilities capable for materials and electrical characterizations to support production and new product
development. Computer simulation is used to validate both mechanical and electrical models in comparison to measurement results. Enhancement of Shadow Moiré and Micro Moiré equipment was carried out to support MCP and flip chip package
warpage and residue stress characterization. In Advanced Packaging Lab, rheology measurement capability was established, aimed at expanding capability for material selection and inspection to support flip chip introduction and various resin
characterizations. A new analytical laboratory has been builted out in our bumping line providing timely support to manufacturing operations.

Quality Control

We
believe that our reputation for high quality and reliable services have been an important factor in attracting and retaining leading international semiconductor companies as customers for our testing and assembly services. We are committed to
delivering semiconductors that meet or exceed our customers specifications on time and at a competitive cost. We maintain quality control staff at each of our facilities.

As of March 31, 2015, we employed 412 personnel for our quality control activities. Our quality control staff typically includes
engineers, technicians and other employees who monitor testing and assembly processes in order to ensure high quality. We employ quality control procedures in the following critical areas:



| |  |  | sales quality assurance: following market trends to anticipate customers future needs;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | design quality assurance: when developing new testing and assembly processes;
| | - |  | -----------------------------------------------------------------------------



| |  |  | supplier quality assurance: consulting with our long-term suppliers;
| | - |  | --------------------------------------------------------------------



| |  |  | manufacturing quality assurance: through a comprehensive monitoring program during mass production; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | service quality assurance: quickly and effectively responding to customers claims after completion of sale.
| | - |  | ------------------------------------------------------------------------------------------------------------

All of our facilities have obtained ISO/TS 16949 quality system certification. In addition, our facilities in Hsinchu and Tainan have
been ISO 9002 certified in September 1997 and December 1998, respectively and recertified with ISO 9001 for substantial revision since 2000. ThaiLin and ChipMOS Shanghai also obtained ISO/TS 16949 quality system certification in September 2005 and
January 2006, respectively.

ISO/TS 16949 certification system seeks to integrate quality management standards into the
operation of a company, and emphasizes the supervision and measurement of process and performance. An ISO 9002 certification is required by many countries for sales of industrial products.

In addition to the quality management system, we also earned the 1998 QC Group Award from
The Chinese Society of Quality, which is equivalent to the similar award from the American Society of Quality. In 2003, ChipMOS passed SONY Green Partner (Tier 2) certification through its ProMOS channel, and in 2009, ChipMOS obtained SONY Green
Partner (Tier 1) certification due to its direct business relationship with SONY. ChipMOS Shanghai also obtained SONY Green Partner (Tier 2) certification through its ISSI channel in 2008. Our laboratories have also been awarded Chinese National
Laboratory accreditation under the categories of reliability test, electricity and temperature calibration.

Our testing and
assembly operations are carried out in clean rooms where air purity, temperature and humidity are controlled. To ensure the stability and integrity of our operations, we maintain clean rooms at our facilities that meet U.S. federal 209E class 100,
1,000, 10,000 and 100,000 standards. A class 1,000 clean room means a room containing less than 1,000 particles of contaminants per cubic foot.

We have established manufacturing quality control systems that are designed to ensure high-quality services to our customers and maintain reliability and high production yields at our facilities. We
employ specialized equipment for manufacturing quality and reliability control, including:



| |  |  | Joint Electron Device Engineering Council (JEDEC) standardized temperature cycling, thermal shock and pressure cook reliability tests;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | high and low temperature storage life tests, temperature humidity bias test and highly accelerated temperature/humidity stress test (HAST); and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | high resolution scanning acoustic tomography, scanning electronic microscope and X-Ray microscopy for physical failure analysis, curve tracer and
semi-probe station for electrical failure analysis.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, to enhance our performance and our
research and development capabilities, we also installed a series of high-cost equipment, such as temperature humidity bias testers, low temperature storage-life testers and highly accelerated stress testers. We believe that many of our competitors
do not own this equipment.

As a result of our ongoing focus on quality, in 2014, we achieved monthly assembly yields of an
average of 99.96% for our memory and logic/mixed-signal assembly packages, 99.97% for our COF packages, 99.95% for our COG packages and 99.91% for our bumping products. The assembly yield, which is the industry standard for measuring production
yield, is equal to the number of integrated circuit packages that are shipped back to customers divided by the number of individual integrated circuits that are attached to leadframes or organic substrate.

Raw Materials

Semiconductor testing requires minimal raw materials. Substantially all of the raw materials used in our memory and logic/mixed-signal
semiconductor assembly processes are interconnect materials such as leadframes, organic substrates, gold wire and molding compound. Raw materials used in the LCD and other flat-panel display driver semiconductor testing and assembly process include
carrier tape, resin, spacer tape, plastic reel, aluminum bags, and inner and outer boxes. Cost of raw materials represented 23% and 21% of our revenue in 2013 and 2014, respectively.

We do not maintain large inventories of leadframes, organic substrates, gold wire or molding compound, but generally maintain sufficient
stock of each principal raw material for approximately one months production based on blanket orders and rolling forecasts of near-term requirements received from customers. In addition, since the commencement of economic downturn in second
quarter of 2008, due to the volatility of the semiconductor market, several of our principal suppliers have also ceased to stock inventories to be reserved to meet its customers production requirements. Instead, our suppliers now require
longer lead time for delivery of our supply orders. Shortage in the supply of materials experienced by the semiconductor industry have in the past resulted in price adjustments. Our principal raw material supplies have not been impacted by the Japan
earthquake and tsunami catastrophe. See Item 3. Key InformationRisk FactorsRisks Relating to Our BusinessIf we are unable to obtain raw materials and other necessary inputs from our suppliers in a timely and
cost-effective manner, our production schedules would be delayed and we may lose customers and growth opportunities and become less profitable for a discussion of the risks associated with our raw materials purchasing methods. For example,
with the exception of aluminum bags and inner and outer boxes, which we acquire from local sources, the raw materials used in our TCP/COF process and for modules are obtained from a limited number of Japanese suppliers.

Competition

The independent testing and assembly markets are very competitive. Our competitors include large IDMs with in-house testing and assembly capabilities and other independent semiconductor testing and
assembly companies, especially those offering vertically integrated testing and assembly services, such as Advanced Semiconductor Engineering Inc., Amkor Technology, Inc., Chipbond Technology Corporation, King Yuan Electronics Co., Ltd., Powertech
Technology, Siliconware Precision, STATS ChipPAC Ltd. and United Test and Assembly Center Ltd. We believe that the principal measures of competitiveness in the independent semiconductor testing industry are:



| |  |  | engineering capability of software development;
| | - |  | -----------------------------------------------



| |  |  | quality of service;
| | - |  | -------------------



| |  |  | flexibility;
| | - |  | ------------



| |  |  | capacity;
| | - |  | ---------



| |  |  | production cycle time; and
| | - |  | --------------------------



| |  |  | price.
| | - |  | ------

In
assembly services, we compete primarily on the basis of:



| |  |  | production yield;
| | - |  | -----------------



| |  |  | production cycle time;
| | - |  | ----------------------



| |  |  | process technology, including our COF technology for LCD and other flat-panel display driver semiconductor assembly services;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | quality of service;
| | - |  | -------------------



| |  |  | capacity;
| | - |  | ---------



| |  |  | location; and
| | - |  | -------------



| |  |  | price.
| | - |  | ------

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:



| |  |  | firstly, 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;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | secondly, we generally have lower unit costs because of our higher utilization rates and thus enabling us to operate at a more cost-effective structure
compared to the IDMs; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

Intellectual Property

As of March 31, 2015, we held 425 patents in Taiwan, 161 patents in the United States, 230 patents in the Peoples Republic of
China and 1 patent in the United Kingdom, France, Germany, Japan, and the Republic of Korea respectively, relating to various semiconductor testing and assembly technologies. These patents will expire at various dates through to 2034. As of
March 31, 2015, we also had a total of 27 pending patent applications in the United States, 53 in Taiwan, 68 in the Peoples Republic of China, 3 in Europe, 1 in Japan, and 2 in the Republic of Korea. In addition, we have registered
ChipMOS and its logo and InPack as trademarks in Taiwan, and ChipMOS and its logo as trademarks in the United States, the Peoples Republic of China, Singapore, Hong Kong, Korea, Japan and the European
Community.

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 costs and a diversion of our resources. See
Item 3. Key InformationRisk FactorsRisks Relating to Our BusinessDisputes over intellectual property rights could be costly, deprive us of technologies necessary for us to stay competitive, render us unable to provide some of
our services and reduce our opportunities to generate revenue and Item 8. Financial InformationLegal Proceedings.

Government Regulations

As discussed above under Intellectual Property, governmental regulation of our intellectual property may materially affect our business. The failure to protect our property rights would
deprive us of our ability to stay competitive in the semiconductor industry. Our intellectual property rights are protected by the relevant patent and intellectual property agencies of the European Community, United States, the Peoples
Republic of China, Singapore, Hong Kong, Korea, Japan and Taiwan.

Environmental Matters

Semiconductor testing does not generate significant pollutants. The semiconductor assembly process generates stationary acid, alkali and
VOC pollutions, principally at the plating stages. Liquid waste is produced when silicon wafers are ground thinner and diced into chips with the aid of diamond saws and cleaned with running water. The bumping process also generates stationary acid,
alkali, liquid waste and VOC pollutions. In addition, excess materials, either on lead-frames or molding process, are removed from assembled semiconductors in the trimming and de-junking processes, respectively. We have installed various types of
wastewater and air pollutants treatment equipments at our assembly and bumping facilities. Since 2001, we have adopted certain environmentally-friendly production management systems, and have implemented certain measures intended to bring our
assembly process in compliance with the Restriction of Hazardous Substances Directive 2002/95/EC issued by the European Union and our customers. We believe that we have adopted adequate and effective environmental protection measures that are
consistent with semiconductor industry practices in Taiwan and Mainland China. In addition, we believe we are in compliance in all material respects with current environmental laws and regulations applicable to our operations and facilities.

All of our facilities in Taiwan and Mainland China have been certified as meeting the ISO 14001 environmental standards of
the International Organization for Standardization, and all of our facilities in Taiwan have been certified as meeting the OHSAS18001 standards of the International Organization for Standardization. Our facilities at Hsinchu Science Park, Chupei and
Southern Taiwan Science Park have won numerous awards including Green Factory Label, ISO50001, ISO14064, ISO14067 and WFN (Water Footprint) in 2014, Smart Green Building Label in 2013, health promotion awards granted by Department of Health of ROC
since 2012, Safety & Health Performance Certification Unit from Council of the Labor Affairs of ROC in 2009 and 2010. Our bumping facility has won Civil Defense Excellent Award from Hsin-chu City in 2009, 2010, 2011
and 2012. We continue to encourage our employees to attend and participate in community environmental campaigns and events to promote and build better environmental friendly practices.

We will continue to implement programs, measures and related training to reduce industrial waste, save energy and control pollution. In
2001, ChipMOS Taiwan completed a lead-free process control program, which offers a lead-free method in a semiconductor package, lead-free plating, lead-free solder ball and lead-free reliability method and specification. In 2005, ChipMOS Shanghai
completed a similar lead-free process control program. In 2003 and 2008, ChipMOS Taiwan and ChipMOS Shanghai obtained Green Partner certification from Sony Corporation of Japan, respectively. The Green Partner program requires external suppliers to
meet SONYs Green Partner requirements. In 2009, we obtained SGS recognition and received the Greenhouse Gas Verification Statement. In 2013 and 2014, we further obtained many SGS recognition and received the Carbon footprint
Verification Statement. The SGS recognitions affirm our eligibility under the Green Partner program and more importantly our commitments towards becoming a green, environmental friendly entity. Standardizing on green, environmentally
friendly products, production facilities and management systems, which has become an industry trend, and to many companies, is a key criteria in selection of their service providers.

Insurance

We maintain insurance policies on our buildings, equipment and
inventories. These insurance policies cover property damages due to all risks, including but not limited to, fire, lightning and earthquakes. The maximum coverage of property insurance for ChipMOS Taiwan and ThaiLin is approximately NT$56,627
million and NT$7,173 million, respectively. ChipMOS Shanghai also maintains property insurance policies for a maximum coverage of approximately RMB919 million.

Insurance coverage on facilities under construction is maintained by us and our contractors, who are obligated to procure necessary insurance policies and bear the relevant expenses of which we are the
beneficiary. We also maintain insurance on the wafers delivered to us while these wafers are in our possession and during transportation from suppliers to us and from us to our customers.

Employees

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

Equipment

Testing of Memory and Logic/Mixed-Signal Semiconductors

Testing equipment is the most capital-intensive component of the memory and logic/mixed-signal semiconductors testing business. Upon the acquisition of new testing equipment, we install, configure,
calibrate and perform burn-in diagnostic tests on the equipment. We also establish parameters for the testing equipment based on anticipated requirements of existing and potential customers and considerations relating to market trends. As of
March 31, 2015, we operated 549 testers for testing memory and logic/mixed-signal semiconductors. We generally seek to purchase testers with similar functionality that are able to test a variety of different semiconductors. We purchase testers
from international manufacturer, Advantest Corporation.

In general, particular semiconductors can be tested using a limited
number of specially designed testers. As part of the qualification process, customers will specify the machines on which their semiconductors may be tested. We often develop test program conversion tools that enable us to test semiconductors on
multiple equipment platforms. This portability among testers enables us to allocate semiconductor testing across our available testing capacity and thereby improve capacity utilization rates. If a customer requires the testing of a semiconductor
that is not yet fully developed, the customer consigns its testing software programs to us to test specific functions. If a customer specifies testing equipment that is not widely applicable to other semiconductors we test, we require the customer
to furnish the equipment on a consignment basis.

We will continue to acquire additional testing equipment in the future to
the extent market conditions, cash generated from operations, the availability of financing and other factors make it desirable to do so. Some of the equipment and related spare parts that we require have been in short supply in recent years.
Moreover, the equipment is only available from a limited number of vendors or is manufactured in relatively limited quantities and may have lead time from order to delivery in excess of six months.

Assembly of Memory and Logic/Mixed-Signal Semiconductors

The number of wire bonders at a given facility is commonly used as a measure of the assembly capacity of the facility. Typically, wire bonders may be used, with minor modifications, for the assembly of
different products. We purchase wire bonders principally from Shinkawa Co., Ltd. and Kulicke & Soffa Industries Inc. As of March 31, 2015, we operated 1,105 wire bonders. In addition to wire bonders, we maintain a variety of other
types of assembly equipment, such as wafer grinders, wafer mounters, wafer saws, die bonders, automated molding machines, laser markers, solder platers, pad printers, dejunkers, trimmers, formers, substrate saws and lead scanners.

Gold Bumping, Testing and Assembly of LCD and Other Flat-Panel Display Driver Semiconductors

We acquired TCP-related equipment from Sharp to begin our TCP-related services. We subsequently purchased additional
TCP-related testers from Yokogawa Electric Corp. and Advantest Corporation and assembly equipment from Shibaura Mechatronics Corp., Shinkawa Co., Ltd., Athlete FA Corp., Daitron Electron Corp. and GMM Corp. As of March 31, 2015, we operated 8
steppers and 19 sputters for gold bumping, 131 inner-lead bonders for assembly and 389 testers for LCD and other flat-panel display driver semiconductors. We are currently in the process of purchasing additional testing equipment. The testing
equipment can be used for the TCP, COF and COG processes, while the inner-lead bonders are only used in the TCP and COF processes. The same types of wafer grinding, auto wafer mount and die saw equipment is used for the TCP, COF and COG processes.
In addition, auto inspection machines and manual work are used in the COG process, which is more labor-intensive than the TCP and COF processes.

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

This discussion and analysis should be read in conjunction with our consolidated financial statements and related notes contained in this Annual Report on Form 20-F.

Overview

We provide a
broad range of back-end testing services, including wafer probing and final testing of memory and logic/mixed-signal semiconductors. We also offer a broad selection of leadframe-based and organic substrate-based package assembly services for memory
and logic/mixed-signal semiconductors. Our advanced leadframe-based packages include thin small outline packages, or TSOPs, and our advanced organic substrate-based packages include fine-pitch ball grid array, or fine-pitch BGA, packages. In
addition, we provide gold bumping, testing and assembly services for LCD and other flat-panel display driver semiconductors by employing TCP, COF and COG technologies. In 2014, our consolidated revenue was NT$22,005 million (US$696 million) and our
profit for the year attributable to equity holders of the Company was NT$1,663 million (US$53 million).

We are a holding
company, incorporated in Bermuda on August 1, 2000. We provide most of our services through our majority-owned subsidiary, ChipMOS Taiwan, and its subsidiaries and investees. ChipMOS Taiwan was incorporated in Taiwan in July 1997 as a joint
venture company of Mosel and Siliconware Precision and with the participation of other investors. Following the completion of the share exchange transaction between ChipMOS Bermuda and ChipMOS Taiwan on September 14, 2007, ChipMOS Taiwan became
a wholly-owned subsidiary of ChipMOS Bermuda. In February 2010, we agreed to sell 15.8% of ChipMOS Taiwans outstanding shares to Siliconware Precision. The share purchase transaction was completed in January 2011. As part of ChipMOS
Taiwans listing plan on the TWSE, on April 16, 2013, we completed the sale of 6.5 million outstanding ChipMOS Taiwan shares or 0.8% of the total number of ChipMOS Taiwans outstanding shares, at the price of NT$15.0 per share to
ChipMOS Taiwans underwriters for the TWSE listing plan and to certain others, including non-US employees of ChipMOS Taiwan. Also, from September 2, 2013 to October 3, 2013, we completed another sale of 180 million outstanding
ChipMOS Taiwan shares or 21.4% of the total number of ChipMOS Taiwans outstanding shares, at the price of NT$20.0 per share to investors. On April 9, 2014, ChipMOS Bermuda sold approximately 1.3 million ChipMOS Taiwan shares as
green shoe option to market investors. ChipMOS Taiwan became listed and commenced trading on the main board of TWSE on April 11, 2014. As of March 31, 2015 we own approximately 522 million or 60.4% of ChipMOS Taiwan shares
without any green shoe option outstanding. See Item 3. Key InformationRisk FactorsRisk Relating to Our Corporate StructureChipMOS Taiwans ability to maintain its listing and trading status on the Taiwan
Stock Exchange is dependent on factors outside of the Company or ChipMOS Taiwans control and satisfaction of stock exchange requirements. ChipMOS Taiwan may not be able to overcome such factors that disrupt its trading status on the main board
of Taiwan Stock Exchange or satisfy other eligibility requirements that may be required of it in the future for additional information. In Taiwan, we conduct testing operations in our facilities at the Hsinchu Science Park and the Hsinchu
Industrial Park, gold bumping and wafer testing in our facility at Chupei, and testing and assembly operations in our facility at the Southern Taiwan Science Park. We also conduct operations in Mainland China through ChipMOS Shanghai, a wholly-owned
subsidiary of Modern Mind. ChipMOS Shanghai operates a testing and assembly facility at the Qingpu Industrial Zone in Shanghai. In April 2011, ChipMOS Bermuda entered into the MMT Assignment Agreement with ThaiLin to sell the MMT Notes to ThaiLin
for a purchase price of approximately US$40 million. The MMT Assignment Agreement transaction was completed on October 3, 2011 and Modern Mind then became the wholly-owned subsidiary of ThaiLin. See Item 4. Information on the
CompanyOur Structure and History for more details. Through our subsidiaries, we also have equity interests in other companies that are engaged in the semiconductor industry.

The following key trends are important to understanding our business:

Capital Intensive Nature of Our Business. Our operations, in particular our testing operations, are characterized by relatively
high fixed costs. We expect to continue to incur substantial depreciation and other expenses as a result of our previous acquisitions of testing and assembly equipment and facilities. Our profitability depends in part not only on absolute pricing
levels for our services, but also on capacity utilization rates for our testing and assembly equipment. In particular, increases or decreases in our capacity utilization rates could significantly affect our gross margins since the unit cost of
testing and assembly services generally decreases as fixed costs are allocated over a larger number of units.

The current
generation of advanced testers typically cost between US$1 million and US$5 million each, while wire bonders used in assembly typically cost approximately US$68 thousand each and inner-lead bonders for TCP and COF assembly cost approximately US$360
thousand each and COG chip sorters cost approximately US$220 thousand each. We begin depreciating our equipment when it is placed into commercial operation. There may be a time lag between the time when our equipment is placed into commercial
operation and when it achieves high levels of utilization. In periods of depressed semiconductor industry conditions, we may experience lower than expected demand from our customers and a sharp decline in the average selling prices of our testing
and assembly services, resulting in an increase in depreciation expenses relative to revenue. In particular, the capacity utilization rates for our testing equipment may be severely adversely affected during a semiconductor industry downturn as a
result of the decrease in outsourcing demand from integrated device manufacturers, or IDMs, which typically maintain larger in-house testing capacity than in-house assembly capacity.

Highly Cyclical Nature of the Semiconductor Industry. The worldwide semiconductor industry has experienced peaks and troughs over
the last decade, with a severe downturn beginning in the fourth quarter of 2000 that was followed by a recovery in early 2003. The significant decrease in market demand for semiconductors that began in 2000 adversely affected our results of
operations for 2001 and 2002. Beginning in the fourth quarter of 2008, the semiconductor industry commenced another significant downturn which continued in 2009 and in 2010. Market demand for semiconductors significantly decreased across our
industry during these periods, which adversely affected average selling prices for our services and our results of operations for 2008, 2009 and 2010. The impact on our results of operations of the decrease in market demand during these periods was
partly offset by increases in our 2009 and 2010 revenue from assembly services for logic/mixed-signal semiconductors due to higher customer demand for these services in 2009 and 2010. The overall outsourced assembly and testing services for memory
and logic/mixed-signal semiconductors increased gradually each year since 2010, continuing in 2013 and 2014. During periods of decreased demand for assembled semiconductors, some of our customers may forego, delay or simplify final testing of
certain types of semiconductors, such as DRAM, which may further decrease demand and average selling prices for our services and intensify our difficulties related to realizing pricing levels, capacity utilization rates and gross margin during these
periods.

Declining Average Selling Prices of Our Testing and Assembly Services. The semiconductor industry is
characterized by a general decrease in prices for products and services over the course of their product and technology life cycles. The rate of decline is particularly steep during periods of intense competition and adverse market conditions. The
average selling prices of our testing and assembly services experienced sharp declines during such periods as a result of intense price competition from other independent testing and assembly companies that attempt to maintain high capacity
utilization levels in the face of reduced demand.

To offset the effects of decreasing average selling prices, we will
continue to seek to:



| |  |  | improve production efficiency and attain high capacity utilization rates;
| | - |  | -------------------------------------------------------------------------



| |  |  | concentrate on testing of potentially high-demand, high-growth semiconductors;
| | - |  | ------------------------------------------------------------------------------



| |  |  | develop new assembly technologies; and
| | - |  | --------------------------------------



| |  |  | implement new technologies and platforms to shift into potentially higher margin services.
| | - |  | ------------------------------------------------------------------------------------------

Market Conditions for the End-User Applications for Semiconductors. Market conditions in the semiconductor industry, to a large
degree, track those for their end-user applications. Any deterioration in the market conditions for the end-user applications of semiconductors that we test and assemble may reduce demand for our services and, in turn, materially adversely affect
our financial condition and results of operations. Despite an increase in the demand for mobile/niche DRAM in 2010, for DRAMs with more advanced features such as that of enhanced graphic capability, increased power efficiency and increased mobility,
the average market demand for DRAM remained low since 2010 until 2013. Our revenue is largely attributable to fees from testing and assembling semiconductors for use in personal computers, consumer and portable electronic products, display
applications and communications equipment. The markets for these products are intensely competitive, and a significant decrease in demand puts pricing pressure on our testing and assembly services and negatively affects our earnings. The oversupply
of DRAM products in the second half of 2007 and the weak demand in the DRAM market in 2008 and in the first quarter of 2009 resulted in significant reductions in the price of DRAM products, which in turn drove down the average selling prices for our
testing and assembly services for DRAM products from the second half of 2009 and continue in 2013.

Change in Product Mix.Declines in average selling prices since 2009 have been
partially offset by a change in our revenue mix. In particular, revenue from testing and assembly of LCD and other flat-panel display driver semiconductors, bumping services and 12-inch wafer processing have increased as a percentage of our total
revenue over the 2009 to 2013 period. We intend to continue focusing on testing and assembling more semiconductors that have the potential to provide higher margins and developing and offering new technologies in testing and assembly services, in
order to mitigate the effects of declining average selling prices on our ability to attain profitability.

Recent Acquisitions

As part of ChipMOS Taiwans listing plan on the TWSE, on April 16, 2013, we completed the sale of
6.5 million outstanding ChipMOS Taiwan shares or 0.8% of the total number of ChipMOS Taiwans outstanding shares, at the price of NT$15.0 per share to ChipMOS Taiwans underwriters for the TWSE listing plan and to certain others,
including non-US employees of ChipMOS Taiwan. Also, from September 2, 2013 to October 3, 2013, we completed another sale of 180 million outstanding ChipMOS Taiwan shares or 21.4% of the total number of ChipMOS Taiwans
outstanding shares, at the price of NT$20.00 per share to investors. On April 9, 2014, ChipMOS Bermuda sold approximately 1.3 million ChipMOS Taiwan shares as green shoe option to market investors. ChipMOS Taiwan became listed
and commenced trading on the main Board of TWSE on April 11, 2014. As of March 31, 2015, we owned approximately 522 million ChipMOS Taiwan shares representing 60.4% of ChipMOS Taiwans outstanding shares without any green
shoe option outstanding. See Item 4. Information on the CompanyOur Structure and History for description of our earlier merger events.

Our revenue consists primarily of service fees for testing and assembling semiconductors, and to a lesser
extent, fees from equipment rentals to semiconductor manufacturers for engineering testing, less allowances for product returns. We offer testing and assembly services for memory semiconductors, logic/mixed-signal semiconductors, testing and
assembly services for LCD and other flat-panel display driver semiconductors and bumping services.

Most of our customers do
not place purchase orders far in advance and our contracts with customers generally do not require minimum purchases of our products or services. Our customers purchase orders have varied significantly from period to period because demand for
their products is often volatile. We have strategically entered into long-term capacity agreements with some of our customers. Under certain of those long-term agreements, we have agreed to reserve capacity for our customers and our customers have
agreed to place orders in the amount of the reserved capacity (which is subject in certain cases to reduction by the customers). As part of our strategy, we intend to continue entry into additional long-term capacity agreements as well as focus on
our business with smaller customers or customers who do not place orders on a regular basis. We believe that the dual focused strategy would assist us to be better prepared for the current economic volatility and ensure maximum utilization rate of
our capacity and help us to develop closer relationships with all types of our customers. Depending on customer demands, market conditions and other considerations, we remain to be focused on expansion of our operations outside Taiwan and Mainland
China in connection with possible future long-term capacity agreements.

Our financial condition and results of operations have also been, and are likely to continue
to be, affected by price pressures on our service fees, which tend to decline in tandem with the declining average selling prices of the products we test and assemble over the course of their product and technology life cycles. In order to maintain
our margins, it is necessary to offset the fee erosion by continually improving our production efficiency and maintaining high capacity utilization rates. We also plan to continue to develop and implement new technologies and expand our services
into potentially higher-margin segments. These efforts require significant upfront investment in advance of incremental revenue, which could impact our margins.

Pricing

We price our testing fees primarily based on the cost of testing
the products to our customers specifications, including the costs of the required material and components, the depreciation expenses relating to the equipment involved and our overhead expenses, and with reference to prevailing market prices.
Accordingly, the testing fee for a particular product would principally depend on the time taken to perform the tests, the complexity of the product and the testing process, and the cost of the equipment used to perform the test. For example,
testing fees for memory semiconductors are significantly higher than those for other products because of the longer time required and the need for burn-in testing.

We price our assembly services on a per unit basis, taking into account the complexity of the package, our costs, including the costs of the required material and components, the depreciation expenses
relating to the equipment involved and our overhead expenses, prevailing market conditions, the order size, the strength and history of our relationship with the customer and our capacity utilization.

We price our testing and assembly services for LCD and other flat-panel display driver semiconductors and bumping services on the basis
of our costs, including the costs of the required material and components, the depreciation expenses relating to the equipment involved and our overhead expenses, and the price for comparable services.

We offer volume discounts to all customers who purchase large quantities of our services and special discounts to customers who use our
vertically integrated services. On a case by case basis, we also may offer special payment terms, including longer payment cycles, to key customers during downturns in the market so as to retain business from such key customers.

Revenue Recognition

We generally recognize our revenue upon completion of testing and assembly services. We also recognize our revenue upon shipment of tested and assembled semiconductors to locations designated by our
customers, including our internal warehouse for customers using our warehousing services. We submit invoices at the time of completion of service or shipment or delivery and generally require all customers to pay within 60 days after the last day of
the month during which the invoice was sent.

We experienced collection problems for our services of receivables from ProMOS
and Spansion in 2008 and 2009, respectively. See Item 4. Information on the Company  Customers for more information.

We have not experienced other significant collection problems for our services.

Related Party Revenues

In 2013 and 2014, no revenue was derived from related parties. While we believe that our transactions with related parties were entered into on an arms length basis, we extended them favorable
payment terms, as discussed in the preceding paragraph. See Item 7. Major Shareholders and Related Party Transactions for more information concerning our related party transactions.

Geography and Currency

The majority of our revenue is generated from customers headquartered in Taiwan, which represented 72% and 72% of our revenue in 2013 and 2014, respectively. We also generate revenue from customers in the
United States, Singapore, Korea, Japan and other countries. Our service fees and revenue are generally denominated in the currency of the jurisdiction in which our facilities are located, for example NT dollars for our Taiwan operations and RMB for
our Mainland China operations. As we generate most of our revenue from Taiwanese customers using our Taiwanese operations, and since most of our labor and overhead costs are denominated in NT dollars, we consider the NT dollar to be our functional
currency.

See Note 30 to our consolidated financial statements contained in this Annual Report on Form 20-F and Item
11. Quantitative and Qualitative Disclosure about Market Risk  Market Risks  Foreign Currency Exchange Rate Risks for certain information on our exchange rate risks.

Cost of Revenue and Gross Profit

Our cost of revenue consists primarily of the following: depreciation and amortization expenses, raw material costs, and labor and
overhead expenses, which primarily include expendable equipments, sub-contracting fees and rental expenses. Our operations, in particular our testing, are characterized by relatively high fixed costs. We expect to continue to incur substantial
depreciation and other expenses as a result of our previous and future acquisitions of testing and assembly equipment and facilities, including our investment in our Mainland China operations. As of March 31, 2015, we had 963 testers, 149
burn-in ovens, 1,105 wire bonders, 131 inner-lead bonders, 8 steppers and 19 sputters. We use inner-lead bonders for the assembly of LCD and other flat-panel display driver semiconductors using TCP or COF technology, and wire bonders for TSOP, BGA,
and some other package assembly technologies.

Our profitability depends in part not only on absolute pricing levels for our
services, but also on our capacity utilization rates. Our average capacity utilization rate for testing of memory and logic/mixed-signal semiconductors was 65% in 2013 and 74% in 2014. Our average capacity utilization rate for assembly of memory and
logic/mixed-signal semiconductors was 80% in 2013 and 78% in 2014. Our average capacity utilization rate for LCD and other flat-panel display driver semiconductor testing and assembly was 81% in 2013 and 80% in 2014. In addition, our average
capacity utilization rate for bumping was 87% in 2013 and 85% in 2014.

For each period of time selected, we derived the
capacity utilization rate for our testing operations by dividing the total number of hours of actual use of our facilities testing equipment units by the maximum number of hours that these equipment units were capable of being used. The
testing capacity utilization rate generally increases in correlation to increases in the total volume of our customer orders, and generally decreases in correlation to decreases in the total volume of our customer orders.

For each period of time selected, we derived the capacity utilization rate for our assembly operations by dividing the total number of
units actually produced by our assembly facilities by the maximum number of units that these facilities are capable of producing. The assembly capacity utilization rate generally increases in correlation to increases in the total volume of our
customer orders, and generally decreases in correlation to decreases in the total volume of our customer orders.

Our gross
revenue is generally the product of the total volume of our customer orders multiplied by the average selling price per deliverable unit from our assembly or testing services, as the case may be. As a result, in a period where the average selling
prices do not fluctuate significantly, increases or decreases in our capacity utilization rates generally correlate to increases or decreases in our gross revenue. Periods with significant increases in the average selling prices reduce the negative
impact on our gross revenue from any decreases in our capacity utilization rates. Similarly, periods with significant decreases in the average selling prices reduce the positive impact on our gross revenue from any increases in our capacity
utilization rates.

The Company has significant fixed costs in operating our assembly and testing facilities. For this reason,
decreases in our cost of goods sold during a period generally occur at a slower rate than decreases, during the same period, in our gross revenue due to lower capacity utilization rates, lower average selling prices, or both. Also, as a result, our
gross margin and profitability generally decrease in correlation to decreases in our capacity utilization rates, decreases in our average selling prices, or both. Similarly, our gross margin and profitability generally increase in correlation to
increases in our capacity utilization rates, increases in our average selling prices, or both. Due to the cyclical nature of the semiconductor industry, customer orders may change significantly, causing fluctuation in our capacity utilization rate
and average selling price.

Most of our labor and overhead costs are denominated in NT dollars. However, we also incur costs
of revenues and operating expenses associated with testing and assembly services in several other currencies, including Japanese yen, US dollars and RMB. In addition, a substantial portion of our capital expenditures, primarily for the purchase of
testing and assembly equipment, has been, and is expected to continue to be, denominated in Japanese yen with much of the remainder denominated in US dollars.

Other Non-Operating Income (Expenses), Net

Our other non-operating income principally consists of interest income, foreign exchange gains and gain on disposal of financial assets at
fair value through profit or loss.

Our other non-operating expenses principally consist of impairment of available-for-sale
investments and foreign exchange losses.

Non-controlling Interests

Non-controlling interests represent the portion of our income that is attributable to the shareholding in our consolidated subsidiaries
that we do not own. See Item 4. Information on the CompanyOur Structure and History for information concerning our consolidated subsidiaries. On April 16, 2013, we sold 6.5 million shares or 0.8% of the total number of
ChipMOS Taiwans outstanding shares, at the price of NT$15.0 per share to ChipMOS Taiwans underwriters, Yuanta Securities Company Limited and Capital Securities Corp., and to certain others, including non-US employees of ChipMOS Taiwan.
From September 2, 2013 to October 3, 2013, we sold 180 million shares or 21.4% of the total number of ChipMOS Taiwans outstanding shares, at the price of NT$20.0 per shares to investors. On April 9, 2014, ChipMOS Bermuda
sold approximately 1.3 million ChipMOS Taiwan shares as green shoe option to market investors. After the completion of the aforesaid sales the Company held approximately 522 million ChipMOS Taiwan shares, representing 60.4% of
the total number of ChipMOS Taiwans outstanding shares without any green shoe option outstanding. In 2014, our non-controlling interests were attributable to the non-controlling interests owned by Siliconware Precision and the
public shareholders interests in ChipMOS Taiwan and the public shareholders interests in ThaiLin and ChipMOS Shanghai. As of December 31, 2014 and March 31, 2015, we owned approximately 522 million ChipMOS Taiwan shares,
representing 60.4% of ChipMOS Taiwans outstanding shares.

Profit for the Year Attributable to Equity Holders of the Company

Our profit for the year attributable to equity holders of the Company were NT$1,335 million and NT$1,663 million (US$53
million) in 2013 and 2014, respectively. We believe our future results will be dependent upon the overall economic conditions in the markets we serve, the competitive environment in which we operate, and our ability to successfully implement our
strategy, among other things. For additional information on factors that will affect our future performance, see Item 3. Key InformationRisk Factors.

Finance Costs. Finance costs decreased by NT$42 million, or 23%, to finance costs of NT$141 million (US$4 million) in 2014 from NT$183 million in 2013. This change was primarily due to the decrease
of interest on bank loans by NT$48 million (US$2 million).

Other Non-Operating Income (Expenses), Net. Other
non-operating income (expenses), net, changed by NT$102 million, or 35%, to other non-operating income, net, of NT$391 million (US$12 million) in 2014 from other non-operating income, net, of NT$289 million in 2013. This change was primarily due to
the increase of foreign exchange gains by NT$73 million (US$2 million) and interest income by NT$22 million (US$1 million).

Profit before Tax. As a result of the foregoing, profit before tax increased by 58% to NT$3,975 million (US$126 million) in 2014
from NT$2,516 million in 2013.

Income Tax. We had an income tax expense of NT$1,036 million (US$33 million) in 2014
compared to income tax expense of NT$827 million for 2013, primarily due to the increase of profit before tax.

Profit for
the Year Attributable to Non-controlling Interests. The profits of Modern Mind, ChipMOS Shanghai, ChipMOS Taiwan and ThaiLin attributable to non-controlling interests amounted to NT$1,275 million (US$40 million) in 2014, compared to NT$354
million in 2013.

Profit for the Year Attributable to Equity Holders of the Company. As a result of the foregoing, the
profit for the year attributable to the Company was NT$1,663 million (US$53 million) in 2014, compared to NT$1,335 million in 2013.

Year Ended December 31, 2013 Compared to Year Ended December 31, 2012

to NT$6,274 million in 2013 from NT$6,381 million in 2012. Revenue from assembly services for memory semiconductors increased by NT$111 million, or 2%, to NT$5,635 million in 2013 from NT$5,524 million in 2012, primarily as a result of increased
customer demand and capacity utilization rate. Revenue from assembly services for logic/mixed-signal semiconductors decreased by NT$218 million, or 25%, to NT$639 million in 2013 from NT$857 million in 2012, principally due to a decreased average
selling price.

Revenue from LCD and other flat-panel display driver semiconductor testing and assembly services increased by
NT$425 million, or 10%, to NT$4,781 million in 2013 from NT$4,356 million in 2012. This increase was principally as a result of an increase in customer demand and capacity utilization rate for LCD and other flat-panel display products in 2013.

Revenue from bumping services increased by NT$790 million, or 27%, to NT$3,711 million in 2013 from NT$2,921 million in 2012.
This increase was principally as a result of an increase in customer demand, average selling price and the increased capacity utilization rate for bumping services in 2013.

See  Cost of Revenue and Gross Profit for more information concerning our testing and assembly capacity utilization rates and the impact on our revenue, gross profit and profitability
from any increases or decreases in our capacity utilization rate.

Cost of Revenue and Gross Profit. Cost of revenue
decreased by NT$846 million, or 5%, to NT$15,922 million in 2013 from NT$16,768 million in 2012, primarily due to the decrease of depreciation expenses of NT$1,333 million and partially offset by the increases in employee benefit costs, inventory
valuation allowance and operating leases of NT$273 million, NT$92 million and NT$115 million, respectively.

Our gross profit
increased to NT$3,440 million in 2013 from NT$2,453 million in 2012. Our gross margin was 17.8% in 2013, compared to 12.8% in 2012.

year attributable to the Company was NT$1,335 million in 2013, compared to NT$630 million in 2012.

Critical Accounting Policies

Commencing January 1, 2013, we prepare our consolidated financial statements in conformity with the IFRSs. Under the
IFRSs, we are required to make certain estimates, judgments and assumptions about matters that are highly uncertain at the time those estimates, judgments and assumptions are made, and our financial condition or results of operations may be
materially impacted if we use different but nonetheless reasonable estimates, judgments or assumptions about those matters for that particular period or if we change our estimates, judgments or assumptions from period to period.



56

##### Table of Contents

Under the IFRSs, the significant accounting policies are set forth in Note 2 to our
consolidated financial statements contained in this Annual Report on Form 20-F. The significant accounting policies that require us to make estimates and assumptions about the effect of matters that are inherently uncertain are discussed below.

Impairment of receivables

Receivables are assessed for indicators of impairment at the end of each reporting period, and are impaired where there is objective evidence that, as a result of one or more events that occurred after
the initial recognition of the receivables, the estimated future cash flows of the receivables have been impacted. For the customer that we have reason to believe may have an inability to meet its financial obligations, we conduct an individual
examination based on the available facts and circumstances to record a specific reserve. For the customers other than this, a general reserve is established based on a range of percentages applied to aging categories. These percentages are based on
historical collection and write-off experience. If circumstances change, the estimate of the recoverability of amounts due to us could be reduced by a material amount. As of December 31, 2014, we provided NT$7 million (US$231 thousand) for the
first type of reserve and NT$10 thousand (US$315) for the second type of reserve. See Item 4. Information on the CompanyCustomers.

The allowance we set aside for doubtful receivables was NT$7 million as of December 31, 2013 and NT$7 million (US$231 thousand) as of December 31, 2014. The allowances as of December 31,
2013 and 2014 represented 0.2% and 0.1%, respectively, of our accounts receivable as of those dates. The allowance and reversal in 2013 and 2014 reflected an enlargement and reduction of NT$7 million and NT$161 thousand (US$5 thousand),
respectively, in accounts receivable that decreased and increased the sales and marketing expenses. If we were to change our estimate of the allowance for doubtful receivables either upward or downward 10%, our operating profit would be affected by
NT$3 thousand (US$105) for 2014.

An increase in our allowance for doubtful receivables would increase our sales and marketing
expenses, and decrease our current assets.

Depreciation of property, plant and equipment

Property, plant and equipment are depreciated on a straight-line basis over their estimated economic useful lives. The determination of
the useful lives involves managements estimation. The Group assesses annually the useful life of the property, plant and equipment and if the expectation differs from the original estimate, such a difference may impact the depreciation in the
year when the estimate is changed and the future period.

Deferred Tax Assets

Deferred tax assets are recognized for unused tax losses and tax credit to the extent that it is probable that taxable profit will be
available against which the losses can be utilized. Significant management judgement is required to determine that amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable profits together
with future tax planning strategies.

In 2013 and 2014, the Group has NT$1,218 million and NT$915 million (US$29 million) of
tax losses carried forward, respectively. These losses relate to subsidiaries that have a history of losses and may not be used to offset taxable income elsewhere in the Group. The subsidiaries neither have any taxable temporary difference nor any
tax planning opportunities available that could partly support the recognition of these losses as deferred tax assets. On this basis, the Group has determined that it cannot recognize deferred tax assets on the tax losses carried forward.

As of December 31, 2013 and 2014, the ending balances for deferred tax assets were NT$195 million and NT$178 million
(US$6 million), respectively.

Deferred Tax Liabilities

In the opinion of the directors, the Company controls the dividend policy of its subsidiaries in the ROC and it is probable that the
temporary differences arising from the withholding tax on dividends declared in respect of the profits earned by the Companys subsidiaries in the ROC will not reverse in the foreseeable future.

Impairment of Non-Financial Assets

Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its
fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arms length, for similar assets or observable market prices less
incremental costs for disposing of the asset. The value in use calculation is based on a discounted cash flow (DCF) model. The cash flows are derived from the budget for the next five years and do not include restructuring activities
that the Group is not yet committed to or significant future investments that will enhance the assets performance of the cash generating unit being tested. The recoverable amount is sensitive to the discount rate used for the DCF model as well
as the expected future cash-inflows and the growth rate used for the extrapolation purposes.

In determining whether any
impairment charges were necessary for the property, plant and equipment and other non-current assets for the year ended December 31, 2014, we assumed that the semiconductor industry will continue its growth in the next few years. Based upon our
assumption of growth in the semiconductor industry and our other assumptions in our internal budget, for the purpose of determining whether any impairment charges are necessary for the year ended December 31, 2014, nil impairment loss was
recognized with respect to property, plant and equipment and other non-current assets.

While we believe that our estimates of
future cash flows are reasonable, different assumptions regarding such cash flows could materially affect our evaluations.

Defined Benefit Plans

The cost of the defined benefit pension plan and post-employment benefits and the present value of the pension obligation are determined using actuarial valuations. An actuarial valuation involves making
various assumptions that may differ from actual developments in the future. These include the determination of the discount rate, future salary increases, mortality rates and future pension increases. Due to the complexities involved in the
valuation and its long-term nature, a defined benefit obligation is highly sensitive to changes in these assumptions. All assumptions are reviewed at each reporting date. Further details are disclosed in Note 22 to our consolidated financial
statements contained in this Annual Report on Form 20-F.

Share-Based Payments

The Group measures the cost of equity-settled transactions with employees by reference to the fair value of the equity instruments at the
date at which they are granted. Estimating fair value for share-based payments requires determining the most appropriate valuation model for a grant of equity instruments, which is dependent on the terms and conditions of the grant. This also
requires determining the most appropriate inputs to the valuation model including the expected life of the option, volatility and dividend yield and making assumptions about them. The assumptions and models used for estimating fair value for
share-based payments are disclosed in Note 31 to our consolidated financial statements contained in this Annual Report on Form 20-F. In 2014, the share-based compensation expense amounted to NT$282 million (US$9 million), which was taken into
account when determining our profit for the year and shareholders equity for the year ended December 31, 2014.

Senior Managements Discussion with the Audit Committee

Our management has discussed the critical accounting policies described above with the audit committee of our board of directors and the
audit committee has reviewed our disclosure relating to the critical accounting policies in this section.

Impact of
Foreign Currency Fluctuations and Governmental or Political Factors

For a discussion of the impact of foreign currency
fluctuations and governmental economics, fiscal, monetary or political policies or factors that may directly or indirect impact us, see Item 3. Key InformationRisks FactorsRisks Relating to Our BusinessFluctuations in
exchange rates could result in foreign exchange losses and Item 3. Key InformationRisks FactorsRisks Relating to Countries in Which We Conduct Operations.

Liquidity and Capital Resources

Since our inception, we have funded our operations and growth primarily through the issuance of equity, a mixture of short- and long-term loans and cash flow from operations. As of December 31, 2014,
our primary sources of liquidity were cash and cash equivalents of NT$15,265 million (US$483 million), short-term loans of NT$4,247 million (US$134 million) available to us in undrawn facilities, which have expired or will expire from January 2015
to November 2015, and long-term loans of NT$4,000 million (US$127 million) available to us in undrawn facilities, which will expire in July 2019. To meet our liquidity, capital spending and other capital needs, we have taken certain steps discussed
below.

Net Cash Generated from Operating Activities

Net cash generated from operating activities totaled NT$5,600 million (US$177 million) in 2014, compared to NT$6,223 million in 2013. Net
cash generated from operating activities was positively impacted by a profit before tax of NT$3,975 million (US$126 million) with depreciation expenses of NT$2,906 million (US$92 million) in 2014 compared to a profit before tax of NT$2,516 million
with depreciation expenses of NT$3,292 million in 2013. The decrease in net cash generated from operating activities was primarily due to an increase of short-term deposits of NT$87 million (US$3 million) in 2014 compared to a decrease of short-term
deposits of NT$354 million in 2013, an increase of accounts and notes receivable of NT$762 million (US$24 thousand) in 2014 compared to an increase of accounts and notes receivable of NT$2 million in 2013, an increase of inventories of NT$185
million (US$6 million) in 2014 compared to a decrease of NT$168 million in 2013 and an increase of other current assets of NT$569 million (US$18 million) in 2014 compared to an increase of other current assets of NT$1 million in 2013 and partially
offset by an increase of other payables of NT$295 million (US$9 million) in 2014 compared to a decrease of NT$128 million in 2013.

Net cash generated from operating activities totaled NT$6,223 million in 2013, compared to NT$4,527 million in 2012. Net cash generated from operating activities was positively impacted by a profit before
tax of NT$2,516 million with depreciation expenses of NT$3,292 million in 2013 compared to a profit before tax of NT$848 million with depreciation expenses of NT$4,623 million in 2012. The increase in net cash generated from operating activities was
primarily due to a decrease of short-term deposits of NT$354 million in 2013 compared to an increase of short-term deposits of NT$344 million in 2012, an increase of accounts and notes receivable of NT$2 million in 2013 compared to an increase of
accounts and notes receivable of NT$327 million in 2012 and an increase of accounts payable of NT$67 million in 2013 compared to a decrease of accounts payable of NT$241 million in 2012.

Net Cash Used in Investing Activities

Net cash used in investing activities totaled NT$3,325 million (US$105 million) in 2014, compared to NT$3,006 million in 2013. The increase in net cash used in investing activities primarily resulted from
the decrease in proceeds from sales of property, plant and equipment which was NT$4 million (US$126 thousand) in 2014, compared to NT$151 million in 2013 and the increase in acquisition of available-for-sale financial assets which was NT$209 million
(US$7 million) in 2014 compared to nil in 2013.

Net cash used in investing activities totaled NT$3,006 million in 2013,
compared to NT$2,600 million in 2012. The increase in net cash used in investing activities primarily resulted from the increase in capital expenditures which was NT$3,251 million in 2013, compared to NT$2,749 million in 2012. The increase in net
cash used in investing activities also was partially offset by the increase in proceeds from sales of property, plant and equipment which was NT$151 million in 2013, compared to NT$38 million in 2012.

Net Cash (Used in) Generated from Financing Activities

Net cash used in financing activities totaled NT$375 million (US$12 million) in 2014, compared to net cash generated from financing
activities totaled NT$1,305 million in 2013. The decrease in net cash generated from financing activities was primarily the result of the net payments of long-term loans of NT$696 million (US$22 million) in 2014, compared to NT$2,204 million in
2013, net proceeds of short-term loans of NT$982 million (US$31 million) in 2014, compared to NT$420 million in 2013 and the decrease in proceeds from partial disposal of a subsidiary of NT$34 million (US$1 million) in 2014 compared to NT$3,537
million in 2013.

##### Table of Contents

Net cash generated from financing activities totaled NT$1,305 million in 2013, compared to
net cash used in financing activities totaled NT$312 million in 2012. The decrease in net cash used in financing activities was primarily the result of the net payments of long-term loans of NT$2,204 million in 2013, compared to NT$201 million in
2012, net proceeds of short-term loans of NT$420 million in 2013, compared to net payments of short-term loans of NT$180 million in 2012 and the increase in proceeds from partial disposal of a subsidiary of NT$3,537 million in 2013.

Capital Resources

Capital expenditures in 2013 were funded by NT$6,223 million in cash flows from operating activities. Capital expenditures in 2014 were funded by NT$5,600 million (US$177 million) in cash flows from
operating activities.

Steps taken with respect to generating additional working capital and to saving cash are further
discussed under Liquidity and Capital Resources.

Loans

As of December 31, 2014, we had long-term loans of NT$6,068 million (US$192 million) (including current portions of such long-term
loans of NT$1,508 million (US$48 million)). As of December 31, 2014, NT$21 million (US$1 million) of our long-term loans were collateralized by equipment, and NT$47 million (US$1 million) were collateralized by land and buildings and prepaid
rents-land use right owned by ChipMOS Shanghai. As of December 31, 2014, NT$6,000 million (US$190 million) of our long-term loans were collateralized by land and buildings and equipment owned by ChipMOS Taiwan. Our long-term loans were floating
rate loans with a rate between 1.8947% and 3.16545% as of December 31, 2014, repayable quarterly or semi-annually until March 2015 to July 2019.

We had entered into the following syndicated loan and long-term loans facilities:



| |  |  | In February 2006, we obtained a syndicated loan facility from banks in Taiwan in the amount of NT$3,000 million for a term of six years. This loan
facility is secured by ThaiLins facilities at Chupei. The last withdraw date was August 2009, and the facility was adjusted to NT$1,500 million. This loan facility was fully repaid in February 2012.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2014, certain of our property, plant and equipment, restricted short-term
deposits and prepaid rent (land use rights) with an aggregate net book value of NT$7,268 million (US$230 million), NT$80 million (US$3 million) and NT$99 million (US$3 million), respectively, were pledged as collateral mainly for long-term bank
loans, short-term bank loans and customs duty guarantee.

Our unused credit lines for short-term loans, as of
December 31, 2014, totaled NT$4,247 million (US$134 million), which have expired or will expire from January 2015 to November 2015. As of December 31, 2014, our unused long-term credit facilities totaled NT$4,000 million (US$127 million)
which will expire in July 2019.

As of December 31, 2014, we had unsecured short-term credit loans for exporting and
importing raw materials in the total amount of NT$617 million (US$20 million), which were due between February 2015 and May 2015, and unsecured export loan in the total amount of NT$1,127 million (US$36 million), which were due between January 2015
to March 2015, and secured short term loan for importing raw materials in the total amount of NT$24 million (US$1 million), which was due in January 2015.

We believe our current cash and cash equivalents, cash flow from operations and available credit facilities will be sufficient to meet our capital spending and other capital needs through the end of 2015.
There can be no assurance regarding these matters, however, considering prevailing global economic conditions which continue to have a negative impact on our ability to accurately forecast our revenues, results of operations and cash position. See
Item 3. Key InformationRisk FactorsRisks Relating to Our BusinessOur significant amount of indebtedness and interest expense will limit our cash flow and could adversely affect our operations.

Taxation

ChipMOS Taiwan
is entitled to tax incentives generally available to Taiwan companies under the ROC Statute of Upgrading Industries, including tax credits of 30% for certain research and development and employee training expenses (and, if the amount of expenditure
exceeds the average amount of expenditure for the preceding two years, 50% of the excess amount may be credited against tax payable) and from 5% to 7% for certain investments in automated equipment and technology. These tax credits must be utilized
within five years from the date on which they were earned. In addition, except for the last year of the five-year period, the aggregate tax reduction from these tax credits for any year cannot exceed 50% of that years income tax liability. In
2012, 2013 and 2014, tax credits resulted in tax savings for ChipMOS Taiwan of approximately NT$33 million, NT$60 million and nil, respectively.

ThaiLin is also entitled to other tax incentives generally available to Taiwan companies
under the ROC Statute of Upgrading Industries, including tax credits of 5% to 7% for certain investment in automated equipment and technology. These tax credits must be utilized within five years from the date on which they were earned. In addition,
except for the last year of the five-year period, the aggregate tax reduction from these tax credits for any year cannot exceed 50% of such years income tax liability. In 2012, 2013 and 2014, tax credits resulted in tax savings for ThaiLin of
approximately NT$21 million, NT$18 million and nil, respectively.

Profit for the year generated by ChipMOS Taiwan and ThaiLin
after January 1, 1998, which is not distributed in the year following the year the profit was generated, is subject to income tax at the rate of 10%. If that profit for the year is subsequently distributed, the income tax previously paid on
that income is credited against the amount of withholding tax payable by shareholders, who are not individuals or entities of the Republic of China (for taxation purposes), in connection with the distribution.

The ROC government enacted the AMT Act that became effective on January 1, 2006. The AMT imposed under the AMT Act is a supplemental
tax which is payable if the income tax payable pursuant to the ROC Income Tax Act is below the minimum amount prescribed under the AMT Act. The taxable income for calculating the AMT includes most income that is exempted from income tax under
various legislations, such as tax holidays and investment tax credits. The AMT rate for business entities is 12%. However, the AMT Act grandfathered certain tax exemptions and tax credits granted prior to the enactment of the AMT. The effects of the
AMT on the tax expenses of ChipMOS Taiwan and ThaiLin were reflected in 2014.

In accordance with the relevant tax rules and
regulations of the PRC, ChipMOS Shanghai is entitled to an income tax exemption starting from the first profit making year, with a full exemption available for the first two years and a 50% exemption available for three additional years thereafter.
As the first profit-making year for ChipMOS Shanghai was 2004, the profits made in the years 2004 and 2005 were fully exempt, and the profits made in the years 2006 through 2008 were subject to a 50% tax exemption. Commencing January 1, 2009,
ChipMOS Shanghai is subject to a 25% tax on profits. Any tax losses can only be carried forward for five years.

Special Committee

Mr. Shih-Jye Cheng, our chairman and chief executive officer, was indicted by the Taipei District Prosecutors Office, or the
prosecutor, in December 2005. Based upon information released by the prosecutor, the indictment alleges that Mr. Shih-Jye Cheng, as instructed by Mr. Hung-Chiu Hu, purchased repurchase notes on January 6, January 13, and
January 28, 2004 from Founder Associates Limited, a British Virgin Islands company affiliated with Mega Securities Co., Ltd. (formerly known as Barits International Securities Co., Ltd.), with an aggregate principal amount of approximately
US$29 million, by using corporate funds from ChipMOS Taiwan and ThaiLin. The indictment further alleges that these repurchase notes were used as a cover to misuse the corporate funds of Mosel, and its affiliated entities, including ChipMOS Taiwan
and ThaiLin, in violation of ROC law. In addition, the indictment alleges that Mr. Hu and others were engaged in the insider trading of the securities of Mosel in violation of ROC law, but none of the current officers at ChipMOS Taiwan or
ThaiLin was indicted in this regard.

In connection with the indictment of Mr. Shih-Jye Cheng by the Taipei District
Prosecutors Office, our board of directors formed a special committee to evaluate the circumstances surrounding the indictment. The special committee has engaged K&L Gates LLP (formerly Kirkpatrick & Lockhart Preston Gates Ellis
LLP) as its independent international legal counsel and Baker & McKenzie as its independent ROC legal counsel, and Ernst & Young (formerly known as Diwan, Ernst & Young) as its accounting advisor to assist in its
evaluation and provide recommendations.

On June 28, 2006, the special committee issued its report, including its
findings and recommendations. Based upon the results of its investigation, it found that: (1) Mr. Cheng has declared himself not guilty of the charges described in the indictment; (2) Baker & McKenzie, after reviewing the
indictment and the prosecutors exhibits, have found that the evidence produced by the prosecutor seems to be inadequate and that there is a low probability of the charges in the indictment being founded; (3) the financial advisor to the
special committee have found that we suffered no loss (not taking into account exchange rate factors) and that all monies (capital and interest) were remitted back to our subsidiaries involved; (4) we have suffered no identifiable harm to our
reputation or our business; and (5) Mr. Cheng has not been impaired by the indictment to perform as our chairman and chief executive officer. The special committee recommended that our board maintains Mr. Cheng as our chairman and chief
executive officer with full responsibilities and our board unanimously (with Mr. Cheng having recused himself) resolved to accept and adopt the special committees recommendation with regard to Mr. Cheng.

##### Table of Contents

Our board of directors also resolved to continue the role of the special committee, for the
duration of the ongoing criminal proceeding involving Mr. Cheng to actively monitor any developments of the criminal investigation and take or recommend any appropriate action in light of such developments.

During its engagement by the special committee, Ernst & Young identified certain internal control weaknesses that existed during
the relevant period of the special committees investigation within ChipMOS Taiwan, ThaiLin and ChipMOS Logic (which was merged into ThaiLin on December 1, 2005). These weaknesses were in areas related to segregation of duties and of
corporate governance on investment authorizations, insufficiency of training for financial personnel in respect of derivative transactions, and non-compliance with the applicable ROC regulations. These identified internal control weaknesses have
either been addressed previously or have been remedied by our company and our subsidiaries.

In light of the identification of
these internal control weaknesses, the special committee recommended that the audit committee of the board of directors lead a special task force and report to the board of the directors as to the effectiveness of the implementation of internal
control over financial reporting, with an aim to enhance our companys financial personnels knowledge of derivative transactions. The board of directors unanimously resolved to accept and adopt the special committees recommendation
in this regard.

In August 2006, we engaged Ernst & Young to design certain employee training sessions regarding
derivative transactions and the applicable accounting treatment for these transactions.

On October 1, 2007, the Taipei
District Court found Mr. Shih-Jye Cheng not guilty, and on October 22, 2007, the prosecutor appealed the Taipei District Court decision at the Taiwan High Court. The Taiwan High Court (the High Court) held numerous trial
hearings from 2008 to 2013. On September 3, 2013, the High Court rendered a not guilty verdict for all defendants in the matter, including Mr. Shih-Jye Cheng. On September 18, 2013, the Taiwan High Court Prosecutors Office has
filed a petition for appeal against the decision dated September 3, 2013 to Taiwans Supreme Court (the Supreme Court). On August 7, 2014 Supreme Court rendered a verdict affirming High Courts not guilty verdict on
September 3, 2013, and Taipei District Courts not guilty decision on October 1, 2007. The Supreme Courts ruling is not subject to appeal and closes the litigation. On August 12, 2014, our board of directors approved to
discharge the special committee.

Share Option Plan and Share
Appreciation Rights Plan

We adopted a broad-based share option plan in 2001, which was amended at a special general
meeting on March 19, 2004 to increase the number of shares available for issuance under the share option plan from 1,450,000 to 2,250,000. In August 2006, we adopted a second broad-based share option plan, which has 1,750,000 shares
available for issuance. In September 2011, we adopted a third broad-based share option plan, which has 1,000,000 shares available for issuance. Each share option plan provides that our directors, officers, employees and those of our affiliates may,
at the discretion of our board of directors or a committee, be granted options to purchase our shares at an exercise price of no less than the par value of our common shares. The board or the committee has completed discretion to determine which
eligible individuals are to receive option grants, the number of shares subject to each grant, the exercise price of all options granted, the vesting schedule to be in effect for each option grant and the maximum term for which each granted option
is to remain outstanding, up to a maximum term of ten years. Shares available for issuance under these plans are replenished by shares that were subject to forfeited and expired share options.

In 2012, we granted 204,316 share options, with an exercise price, at the time of grant, ranging from US$11.1095 to US$11.1435 per share.
In 2012, 103,426 share options were forfeited, 289,268 share options were expired and 668,246 share options were exercised. In 2013, we granted 688,996 share options, with an exercise price, at the time of grant, ranging from US$9.2225 to US$14.0675
per share. In 2013, 75,944 share options were forfeited, 253,194 share options were expired and 500,383 share options were exercised. In 2014, we granted 241,256 share options, with an exercise price, at the time of grant, ranging from US$19.38 to
US$20.3405 per share. In 2014, 113,541 share options were forfeited, 1,658 share options were expired and 390,664 share options were exercised. As of December 31, 2014, we had 1,300,416 share options outstanding, with an exercise price
ranging from US$2.55 to US$21.488.

##### Table of Contents

In September 2006, August 2008 and May 2013 we adopted a share appreciation rights
(SARs) plan pursuant to which we may issue up to 500,000, 750,000 and 1,000,000 cash-settled SARs to our directors, officers, employees and those of our affiliates. Under the share appreciation rights plan, each holder of SARs,
issued thereunder will be entitled to receive, on the applicable exercise date, cash in an amount equal to the excess of the market value of our common shares on such date over the exercise price of such rights. Our board of directors or a relevant
committee thereof has completed discretion over the administration of the share appreciation rights plan, including determining the recipients of the share appreciation right awards, the number of rights awarded, the exercise date, the exercise
price and other relevant terms. Unless earlier terminated by our board of directors or the relevant board committee, the plan will remain effective until September 2016, August 2018 and May 2023.

In 2012, 43,660 SARs were granted, with an exercise price, at the time of grant, ranging from US$11.1095 to US$11.1435. In 2012, 67,375
SARs were forfeited, 154,106 SARs were expired and 231,270 SARs were exercised. In 2013, 521,020 SARs were granted, with an exercise price, at the time of grant, ranging from US$9.2225 to US$14.0675. In 2013, 46,501 SARs were forfeited, 53,375 SARS
were expired and 249,563 SARs were exercised. In 2014, 36,010 SARs were granted, 24,841 SARs were forfeited, 1,264 SARS were expired and 138,489 SARs were exercised. As of December 31, 2014, we had 683,845 SARs outstanding, with an
exercise price, at the time of grant, ranging from US$2.55 to US$20.3405.

Where applicable, the share numbers and exercise
price of our share option plan and share appreciation rights plan disclosed in the foregoing paragraph are adjusted to reflect the effect of the Companys 1-for-every-4 reverse stock split effective on January 21, 2011.

ChipMOS TECHNOLOGIES (Shanghai) LTD.

Since 2002, we have managed our PRC operations, ChipMOS Shanghai, through Modern Mind, our controlled subsidiary. Whilst we did not own
any equity interest in Modern Mind, we had controlled Modern Mind through our ownership of the MMT Notes. Under the MMT Assignment Agreement signed on April 22, 2011, ChipMOS Bermuda agreed to sell the MMT Notes to ThaiLin for a purchase price
of approximately US$40 million subject to certain closing conditions. The Assignment Agreement transaction completed in October 2011 and ThaiLin immediately converted the MMT Notes into common shares of Modern Mind and purchased all of the remaining
common shares of Modern Mind from Jesper, with ChipMOS Shanghai becoming an indirect wholly-owned subsidiary of ThaiLin, through ThaiLins direct wholly-owned subsidiary Modern Mind.

Under a technology transfer agreement dated August 1, 2002 which expired on August 1, 2012, we licensed certain technologies
and systems, and agreed to provide certain technical support and consulting services to ChipMOS Shanghai relating to those technologies and systems, and ChipMOS Shanghai paid an aggregate of US$25 million to us in 2002 for the technology and
services we provide under this agreement. Under another technology transfer agreement dated October 3, 2011 which became effective on August 1, 2012, we licensed certain technologies and systems, and agreed to provide certain technical
support and consulting services to ChipMOS Shanghai relating to those technologies and systems, and ChipMOS Shanghai will pay an aggregate of RMB27 million to us by forty installments on the last day of each quarter during the term of this
agreement.

On July 1, 2010, ChipMOS Bermuda and ChipMOS Shanghai entered into an exclusive services agreement, pursuant
to which ChipMOS Shanghai will provide its services exclusively to ChipMOS Bermuda or customers designated by ChipMOS Bermuda. Under the exclusive services agreement, ChipMOS Bermuda agrees to procure some of the equipment and consign such equipment
for use by ChipMOS Shanghai. The exclusive services agreement has a term of ten years and will automatically be renewed for periods of ten years, unless terminated by either party at least 30 days prior to the expiration of such ten-year term. In
addition, ChipMOS Bermuda may terminate the exclusive services agreement at any time by giving 30 days prior notice.

ThaiLin Semiconductor Corp.

On March 4, 2008, ChipMOS Taiwan made a loan in an amount of NT$145 million that bears interest at a rate of 4.69% per annum to Kolin, a major shareholder of ThaiLin. The loan was originally
secured by a pledge by Kolin of 11 million common shares of ThaiLin. On August 22, 2008, Kolin repaid NT$15 million of the loan. On December 23, 2008, ChipMOS Taiwan notified Kolin to proceed with the transfer of the collaterals
ownership, the payment of unpaid loan and interest accrued in the amount of NT$130 million, and the payment of interest incurred due to loan repayment default under the loan. On January 20, 2009, Kolin informed ChipMOS that it could not fulfill
request made by ChipMOS, including the transfer of shares since it is prohibited to do so under an interim restrictive order of disposition. Subsequently, Kolin was granted on March 27, 2009, pursuant to a ruling of Taiwan District Court on
(Civil Ruling No.7 and No.9 of 2009), the approval for its reorganization and declaration of creditors rights application. Therefore, such shares shall still be deemed as the creditors collateral. ChipMOS made the creditors rights
application on April 21, 2009. On January 31, 2011, a final ruling of Taiwan High Court (Civil Ruling No.186 of 2010) confirmed its approval of the reorganization plan of Kolin. On March 15, 2012, ChipMOS Taiwan entered into an
agreement with Kolin whereby Kolin agreed to dispose of the common shares of ThaiLin that were pledged to ChipMOS Taiwan and use the proceeds to settle the outstanding debt to ChipMOS Taiwan. The loan had been fully repaid and the subject pledge has
been released accordingly in 2013.

As of March 31, 2015, ThaiLin did not hold any of our outstanding shares.
ThaiLins previous holding includes 1,015,158 shares acquired pursuant to ThaiLins enforcement of the collateral provided by ProMOS under the Stock Pledge Agreement dated December 3, 2008, entered into between ThaiLin and ProMOS,
506,364 shares accumulated from the Rule 10b5-1/10b-18 securities purchase program launched in December 2008, and 467,059 shares acquired pursuant to the interest shares payment and 4,485,630 shares acquired pursuant to the conversion of
2009 Notes in March 2011. In November 2012, ThaiLin sold 2,000,000 shares under the Secondary Offering. In May 2013, ThaiLin sold 380,506 shares to Tokyo Seimitsu. In November 2013 and January 2014, ThaiLin sold 2,000,000 shares and 2,093,705
shares, respectively, to ChipMOS Bermuda and the shares were then retired and cancelled.

The share numbers disclosed in the
foregoing paragraph are adjusted to reflect the effect of the Companys 1-for-every-4 reverse stock split effective on January 21, 2011.

Legal Proceedings

In February 2006, ChipMOS Taiwan and ChipMOS USA received notice of a lawsuit filed by Tessera Technologies, Inc., or Tessera. The complaint was initially filed in United States District Court for the
Northern District of California (Civil Action No. C05-04063CW), or the California court. In an amended complaint, Tessera added ChipMOS Taiwan and ChipMOS USA, among several other semiconductor companies, as co-defendants. The amended complaint
alleges that ChipMOS Taiwan, ChipMOS USA and the other co-defendants infringed certain patents owned by Tessera and that ChipMOS Taiwan is in breach of a license agreement with Tessera, or the Tessera license agreement. Tessera also sought
unspecified damages and injunctive relief. ChipMOS Taiwan and ChipMOS USA have responded to the lawsuit by denying Tesseras claims of patent infringement and breach of contract. ChipMOS USA and ChipMOS Taiwan have also raised various
counterclaims for declaratory judgment and related affirmative defenses that the Tessera patents are invalid and unenforceable. In May 2007, the California court, with the concurrence of ChipMOS Taiwan and ChipMOS USA, stayed all litigation in the
California court as a result of a related investigation by the International Trade Commission, or ITC, initiated by Tessera against certain other co-defendants. In addition, a co-defendant in the Tessera lawsuit requested the United States Patent
and Trademark Office to reexamine the patentability of each of Tesseras patents that are at issue in the case in the California court. The requests were granted and, in February 2007, the U.S. Patent and Trademark Office concluded that certain
claims of the patents were invalid on the basis of prior art. In April 2008, ChipMOS Bermuda, ChipMOS USA and ChipMOS Taiwan received notice that Tessera requested the ITC to initiate another investigation alleging that the sale for and after
importation into the United States as well as importation into the United States of certain small format non-tape based BGA semiconductor packages by ChipMOS Bermuda, ChipMOS Taiwan and ChipMOS USA infringe three of the five Tessera patents at issue
in the case pending in the California court. Tessera sought, among other things, an investigation by the ITC and general exclusion orders to prohibit the infringing products from entry into the United States. The ITC initiated the investigation in
May 2008. On March 13, 2009, after the close of discovery, Tessera submitted a request to terminate the proceedings at the ITC, which the judge granted on July 17, 2009. No petitions for review were filed. The ITC issued an order to
terminate the investigation on August 7, 2009. Due to the completion of a companion investigation against other companies by ITC, the stayed litigations in the Northern District of California resumed in January 2012. On July 19, 2012,
Tessera filed a stipulation with the California court dismissing its breach of contract claim against the companies. Accordingly, this litigation was then limited to only Tesseras patent infringement allegations against the companies. A
court-ordered mediation was held on December 13, 2012 but was unsuccessful. On November 8, 2013, we entered into a settlement agreement with Tessera settling the subject matter. As part of the Settlement Agreement, ChipMOS Taiwan agreed to
pay a one-time payment of US$1,375 thousand, including 20% Taiwan tax withholding, to Tessera in exchange for Tessera releasing, discharging and agreeing to never sue ChipMOS Bermuda, ChipMOS Taiwan and ChipMOS USA relating to the license agreement.
On November 9, 2013, the parties filed a stipulation with the Court to dismiss the pending litigation and the case was closed by the court.

In April 1999, Motorola, Inc. (Motorola) and ChipMOS Taiwan entered into an immunity agreement (the Agreement) whereby each party covenanted not to sue each other for the use of
certain Ball Grid Array (BGA) patents. In December 2004, Motorola spun off its semiconductor division, and thereby formed Freescale Semiconductor, Inc. (Freescale), who then assumed Motorolas rights and obligations
under the Agreement. On October 16, 2006, Freescale unilaterally terminated the Agreement, alleging that ChipMOS Taiwan breached the Agreement. ChipMOS Taiwan argued that Freescales unilateral termination of the Agreement has no legal
effect, and continues to accrue royalty payments for products it believes are covered by the Agreement. The payments previously returned by Freescale and accrued by ChipMOS Taiwan have been deposited in a separate escrow account. On July 13,
2009, Freescale alleged that ChipMOS Taiwan breached the Agreement by failing to pay royalties on certain BGA packages assembled by ChipMOS Taiwan. ChipMOS Taiwan filed an answer to deny all allegations, and also filed counterclaims against
Freescale alleging that Freescale engaged in patent misuse by seeking to obtain royalties on certain of ChipMOS Taiwans BGA products that were not covered by any Freescale patent included under the Agreement, and for declaratory judgment of
patent non-infringement and invalidity. On December 11, 2009, Freescale filed a motion to dismiss the declaratory judgment counterclaims filed by ChipMOS Taiwan and to stay all other patent related claims and issues until its breach of contract
claims could be decided. On July 29, 2010, the Court found that the Agreement constituted a Total Sales Royalty agreement, however, Freescales motion was partly denied for patent misuse issue. A mediation was held between the
parties on October 28, 2010 but was unsuccessful. The fact discovery and expert discovery process regarding patent misuse issue closed in middle June 2011. An Order granting Freescales motion for partial summary judgment and denying
ChipMOS cross-motion for partial judgment was given on September 8, 2011. An Order granting in part and denying in part ChipMOS Motion for Reconsideration was given on March 30, 2012. The Court reinstated ChipMOS claims
for patent misuse and its affirmative defenses for patent exhausted, mutual mistake and license. Freescale refiled its motions to strike ChipMOS jury demand and for summary judgment on ChipMOS affirmative defenses of exhaustion, mutual
mistake and license. The Court has granted those motions on January 24, 2013 and later denied ChipMOS Taiwan motion for reconsideration of those rulings in April 2013. On June 20, 2013, ChipMOS Taiwan entered into a settlement
agreement with Freescale to resolve pending lawsuit between the parties in a judicial settlement conference conducted in the Court. As part of the settlement agreement, ChipMOS Taiwan agreed to pay Freescale US$8 million to settle the claims in
exchange the parties entering into a new License Agreement for the use of Freescales BGA packaging technology from 2011 to 2015 and filing a Joint Stipulation for the Dismissal of all claims pending between them. The Joint Stipulation for
Dismissal was filed on July 26, 2013 and the case was closed by the Court.

|Item 10. | Additional Information
|-------- | ----------------------

Description of
Share Capital

Our authorized share capital is US$3,250,000 consists of 62,500,000 common shares of par value US$0.04
per share, and 18,750,000 preferred shares of par value US$0.04 per share.

Common Shares

Each shareholder is entitled to one vote for each common share held on all matters submitted to a vote of shareholders. Cumulative voting
for the election of directors is not provided for in our bye-laws, which means that the holders of a majority of the shares voted can elect all of the directors then standing for election.

##### Table of Contents

Preferred Shares

Currently there are no specific rights attached to the preferred shares. The specific rights of the preferred shares could include rights, preferences or privileges in priority to our common shares and
the establishment of such rights or the delegation to the board of directors to establish such rights will need to be approved by our shareholders. As of March 31, 2015, no preferred shares have been issued by our company.

Bermuda Law

We are an
exempted company organized under the Companies Act 1981 of Bermuda (as amended) (the Bermuda Companies Act). The rights of our shareholders are governed by Bermuda law and our memorandum of association and bye-laws. The Bermuda Companies
Act differs in some material respects from laws generally applicable to United States corporations and their shareholders.

Dividends

Under the Bermuda Companies Act, a company may not declare or pay dividends from time to time by its board of directors if
there are reasonable grounds for believing that the company is, or would after the payment be, unable to pay its liabilities as they become due or that the realizable value of its assets would thereby be less than its liabilities. (However, in order
to avoid the possibility of an unauthorised reduction of capital, the Company complies with former requirement of section 54(1)(b) of the Bermuda Companies Act, i.e. that whenever the board of directors is making determination based on the latter
benchmark - the realizable value of its assets, it should consider whether the realizable value of its assets would thereby be less than the aggregate of its liabilities, issued share capital and share premium accounts, rather
thanliabilities alone.). The holders of common shares are entitled to receive dividends out of assets legally available for such purposes at times and in amounts as our board of directors may from time to time determine. Any
dividend unclaimed for a period of six years from its date of declaration will be forfeited and will revert to our company.

Voting Rights

Under Bermuda law, except as otherwise provided in the Bermuda Companies Act or our bye-laws, questions brought before a
general meeting of shareholders are decided by a majority vote of shareholders present at the meeting. Our bye-laws provide that, subject to the provisions of the Bermuda Companies Act, and except for the resolutions for approving the extraordinary
transaction, any question properly proposed for the consideration of the shareholders will be decided by a simple majority of the votes cast, either on a show of hands or on a poll, with each shareholder present (and each person holding proxies for
any shareholder) entitled to one vote on a show of hands, or on a poll, one vote for each fully paid-up common share held by the shareholder. In the case of an equality of votes cast, the chairman of the meeting shall have a second or casting vote.
Any resolution for any of the following extraordinary transactions will require the approval of shareholders holding at least 70.0% of the total voting rights of all the shareholders having the right to vote at such meeting:



| |  |  | a resolution for the merger, amalgamation or any other consolidation of us with any other company, wherever incorporated;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | a resolution for the sale, lease, exchange, transfer or other disposition of all or substantially all of our consolidated assets; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a resolution for the adoption of any plan or proposal for the liquidation of our company.
| | - |  | -----------------------------------------------------------------------------------------

Rights in Liquidation

Under Bermuda law, in the event of liquidation or winding-up of a company, after satisfaction in full of all claims of creditors and
subject to the preferential rights accorded to any series of preferred shares, the proceeds of the liquidation or winding-up are distributed pro rata in species or in kind among the holders of our common shares in accordance with our bye-laws.

Meetings of Shareholders

Under Bermuda law, a company is required to convene at least one general shareholders meeting as an annual general meeting each calendar year, unless according to the provisions of the Bermuda
Companies Act, shareholders elect to dispense with the holding of annual general meetings. Bermuda law provides that a special general meeting may be called by the board of directors and must be called upon the request of shareholders holding not
less than 10% of the paid-up capital of the company carrying the right to vote. Bermuda law also requires that shareholders be given at least five days advance notice of a general meeting but the accidental omission to give notice to any
person does not invalidate the proceedings at a meeting. Under our bye-laws, we must give each shareholder written notice at least five days prior to the annual general meeting, unless otherwise agreed by all shareholders having the right to vote at
that annual general meeting, and written notice at least five days prior to any special general meeting, unless otherwise agreed by a majority of shareholders having a right to vote at that special general meeting, and together holding at least 95%
of the paid-up capital of the company carrying the right to vote at that meeting.

##### Table of Contents

Under Bermuda law, the number of shareholders constituting a quorum at any general meeting
of shareholders is determined by the bye-laws of the company. Our bye-laws provide that at least two shareholders present in person or by proxy and holding shares representing at least 50% of the total voting rights of all shareholders having the
right to vote at the meeting constitute a quorum. Our bye-laws further provide that, in respect of a general meeting adjourned for lack of quorum, at least two shareholders present in person or by proxy holding shares representing 33 1/3% of the
total voting rights of all shareholders having the right to vote at the meeting constitute a quorum.

Access to Books and Records and
Dissemination of Information

Under Bermuda law, members of the general public have the right to inspect the public
documents of a company available at the office of the Registrar of Companies in Bermuda. These documents include a companys certificate of incorporation, its memorandum of association (including its objects and powers), and any alteration to
its memorandum of association and documents relating to an increase or reduction of authorized share capital. The shareholders have the additional right to inspect the bye-laws of the company, minutes of general meetings, and the companys
audited financial statements, which, unless agreed by all shareholders and directors, must be laid before the annual general meeting. The register of members of a company is also open to inspection by shareholders and by members of the general
public for not less than two hours each day without charge. Any member of the public may require a copy of the register, or of any part thereof, on the payment of a fee. A company is required to keep its register of members at its registered office
or after giving written notice to the registrar of companies in Bermuda, at such other place in Bermuda but may, subject to the provisions of Bermuda law, establish a branch register of members outside Bermuda. We maintain a principal register of
members in Hamilton, Bermuda and a branch register of members in New Jersey, USA. A company is required to keep at its registered office a register of its directors and officers which is open for inspection for not less than two hours each day by
members of the public without charge. Bermuda law does not, however, provide a general right for shareholders to inspect or obtain copies of any other corporate records.

Election or Removal of Directors

Under Bermuda law and our bye-laws,
directors are elected or appointed at an annual general meeting and serve until re-elected or re-appointed or until their successors are elected or appointed, unless they are earlier removed for cause or resign or otherwise cease to be directors
under Bermuda law or our bye-laws.

A director may be removed for cause at a special general meeting of shareholders
specifically called for that purpose, provided that the director is served with at least 14 days notice. The director has a right to be heard at that meeting. Any vacancy created by the removal of a director at a special general meeting may be
filled at that meeting by the election of another director in his or her place or, in the absence of any election by the shareholders, by the board of directors.

Board Actions

Our bye-laws provide that the quorum necessary for the
transaction of business is two individual directors of the board, and that questions arising at a properly convened meeting of the board of directors must be approved by a majority of the votes present and entitled to be cast. In the case of an
equality of votes, the chairman of the meeting is entitled to a second or casting vote.

The board of directors may appoint
any of our directors to act as our managing director or other senior executive, on such terms and conditions as it may determine, including with respect to remuneration.

Amendment of Memorandum of Association and Bye-Laws

Bermuda law provides
that the memorandum of association of a company may, with the consent of the Minister of Finance of Bermuda (if required), be amended by a resolution passed at a general meeting of shareholders of which due notice has been given. Our bye-laws, other
than the bye-law separating our board of directors into three classes, may be amended by the board of directors if the amendment is approved by a majority of votes cast by our directors and by our shareholders by a resolution passed by a majority of
votes cast at a general meeting. Any amendment to our bye-law separating a board of directors into three classes must be approved by our board of directors and by shareholders holding shares representing at least 60% of the total voting rights of
all our shareholders having the right to vote at such general meeting.

Under Bermuda law, the holders of an aggregate of no
less than 20% in par value of a companys issued share capital or any class of issued share capital have the right to apply to the Bermuda Court for an annulment of any amendment of the memorandum of association adopted by shareholders at any
general meeting. Where an application is made, the amendment becomes effective only to the extent that it is confirmed by the Bermuda Court. An application for the annulment of an amendment of the memorandum of association must be made within 21
days after the date on which the resolution altering the companys memorandum of association is passed and may be made on behalf of the person entitled to make the application by one or more of their number as they may appoint in writing for
the purpose. No application may be made by persons voting in favor of the amendment.

Appraisal Rights and Shareholder Suits

Under Bermuda law, in the event of an amalgamation or a merger of two Bermuda companies, a shareholder who did not vote in favour of the
amalgamation or the merger and who is not satisfied that fair value has been paid for such shareholders shares may apply to the Bermuda Court to appraise the fair value of those shares. The Bermuda Companies Act provides that, subject to the
terms of a companys bye-laws, the amalgamation or merger of a Bermuda company with another company requires the amalgamation or merger agreement to be approved by the board of directors and, except where the amalgamation or merger is between a
holding company and one or more of its wholly-owned subsidiaries or between two or more wholly-owned subsidiaries, by meetings of the holders of shares of each company and of each class of such shares at a meeting of the shareholders by seventy-five
percent of the members present and entitled to vote at that meeting in respect of which the quorum shall be two persons holding or representing at least one-third of the issued shares of each company or class, as the case may be. Under our bye-laws,
any resolution proposed for consideration at any general meeting to approve the merger, amalgamation or any other consolidation of our company with any other company, wherever incorporated shall require the approval of our shareholders holding
shares representing at least 70% of the total voting rights of all our shareholders, and the quorum to be at least 2 shareholders present in person or by proxy holdings shares representing at least 50% of the total voting rights of all our
shareholders.

Class actions and derivative actions are generally not available to shareholders under Bermuda law. The Bermuda
Court, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong done to the company where the act complained of is alleged to be beyond the corporate power of the company or is
illegal or would result in the violation of the companys memorandum of association or bye-laws. Further consideration would be given by the Bermuda Court to acts that are alleged to constitute a fraud against the minority shareholders or, for
instance, where an act requires the approval of a greater percentage of the companys shareholders than that which actually approved it.

When the affairs of a company are being conducted in a manner oppressive or prejudicial to the interests of some part of the shareholders, one or more shareholders may apply to the Bermuda Court for an
order regulating the companys conduct of affairs in the future or compelling the purchase of the shares by any shareholder, by other shareholders or by the company.

Exchange Controls

The following discussion is based on the advice of
Appleby, our Bermuda counsel.

The BMA, has designated us as non-resident for exchange control purposes. The BMA has granted
its consent under the Exchange Control Act 1972 and regulations promulgated thereunder for the issue or transfer to non-residents of Bermuda for exchange control purposes of our common shares, subject to the common shares remaining quoted on the
NASDAQ Capital Market.

Share Issuance and Transfers by Non-Bermuda and Bermuda Residents

Under Bermuda law, there are no limitations on the rights of non-Bermuda residents to hold or vote their shares of Bermuda companies.
Because we have been designated as a non-resident for Bermuda exchange control purposes, there are no restrictions on our ability to transfer funds in and out of Bermuda or to pay dividends to United States residents who are holders of our common
shares other than in respect of local Bermuda currency.

Under Bermuda law, we are an exempted company. An exempted company is
exempt from the provisions of Bermuda law, which stipulate that at least 60% of the equity must be beneficially owned by Bermuda persons. Persons regarded as residents of Bermuda for exchange control purposes require specific consent under the
Exchange Control Act 1972 to acquire securities issued by us. The Exchange Control Act 1972 permits companies to adopt bye-law provisions relating to the transfer of securities. None of Bermuda law, our memorandum of association or our bye-laws
imposes limitations on the right of foreign nationals or non-residents of Bermuda to hold our shares or vote such shares.

As
an exempted company, we may not participate in certain business transactions, including, among others: (1) the acquisition or holding of land in Bermuda, except (i) land acquired for its business by way of lease or tenancy agreement for a
term not exceeding fifty years, or (ii) with the consent of the Minister of Finance granted in his discretion, land by way of lease or tenancy agreement for a term not exceeding twenty-one years in order to provide accommodation or recreational
facilities for its officers and employees; (2) the taking of mortgages on land in Bermuda to secure an amount in excess of US$50,000 without the consent of the Bermuda Minister of Finance; (3) the acquisition of any bonds, or debentures
secured on any land in Bermuda except bonds or debentures issued by the Government or a public authority; or (4) the carrying on of business of any kind in Bermuda, except, among others, to carry business with persons outside Bermuda, in
furtherance of our business carried on outside Bermuda or under a license granted by the Bermuda Minister of Finance.

##### Table of Contents

The Bermuda government actively encourages foreign investment in exempted entities like us
that are based in Bermuda but do not operate in competition with local business. In addition to having no restrictions on the degree of foreign ownership, we are subject neither to taxes on our income or dividends nor to any foreign exchange
controls in Bermuda. In addition, there is no capital gains tax in Bermuda, and profits can be accumulated by us without limitation.

Directors Interests

Under our bye-laws, our director may,
notwithstanding his office be a party to, or otherwise interested in, any transaction or arrangement with our company or in which our company is otherwise interested. He or she may also be a director or officer of, or employed by, or a party to any
transaction or arrangement with, or otherwise interested in, any corporate body promoted by our company or in which our company is interested. Therefore, where it is necessary, so long as our director declares the nature of his or her interest at
the first opportunity at a meeting of the board or by writing to the directors as required by the Bermuda Companies Act and our bye-laws, that director shall not by reason of his or her office be accountable to our company for any benefit he or she
derives from any office or employment to which our bye-laws allow him or her to be appointed or from any transaction or arrangement in which our bye-laws allow him or her to be interested, and no such transaction or arrangement shall be liable to be
avoided on the ground of any such interest or benefit. A general notice to our directors by a director or officer declaring that he or she is a director or officer or has an interest in a person and is to be regarded as interested in any transaction
or arrangement made with that person shall be sufficient declaration of interest in relation to any transaction or arrangement so made.

Share Issuance and Transfer

We have been designated as a non-resident for
exchange control purposes by the BMA, whose permission for the issuance and transfer of common shares has been obtained subject to the common shares being quoted on the NASDAQ Capital Market.

The transfer of common shares between persons regarded as non-resident in Bermuda for exchange control purposes and the issuance of
shares after the completion of the currently contemplated offering of our common shares to those persons may be effected without specific consent under the Exchange Control Act 1972 of Bermuda and regulations thereunder subject to the common shares
remaining quoted on the NASDAQ Capital Market. Issuance and transfer of shares to any person regarded as resident in Bermuda for exchange control purposes require specific prior approval under the Exchange Control Act 1972.

There are no limitations on the rights of persons regarded as non-residents of Bermuda for foreign exchange control purposes who own
common shares to hold or vote their common shares. Since we have been designated as a non-resident for Bermuda exchange control purposes, there are no restrictions on our ability to transfer funds in and out of Bermuda or to pay dividends to United
States residents or other non-residents of Bermuda who are holders of common shares, other than in respect of local Bermuda currency. Furthermore, it is not our intent to maintain Bermuda dollar deposits and, accordingly, will not pay dividends on
the common shares in Bermuda currency.

Share certificates are issued only in the names of corporations or individuals, being
the registered holders of shares as represented by such share certificates. Where an applicant for common shares acts in a special capacity, such as an executor or trustee, certificates may, at the request of that applicant, record the capacity in
which the applicant is acting. Our recording of any special capacity, however, shall not be construed as obliging us either to investigate, or to incur any responsibility or liability in respect of, the proper administration of any trust or estate.
Except as ordered by a court of competent jurisdiction or as required by law, regardless of whether or not we have had notice of a trust, no notice shall be taken of any trust, equitable, contingent, future or partial interest in any share or any
interest in any fractional part of a share or any other right in respect of any common shares except an absolute right to the entirety thereof in the registered holder.

Transfer Agent and Registrar

Appleby Management (Bermuda) Ltd. serves as
our principal registrar and transfer agent in Bermuda for the common shares. Computershare Inc. serves as our United States transfer agent and registrar for the common shares.

Bermuda Taxation

This
summary is based on laws, regulations, treaty provisions and interpretations now in effect and available as of the date of this Annual Report on Form 20-F. The laws, regulations, treaty provisions and interpretations, however, may change at any
time, and any change could be retroactive to the date of issuance of our common shares. These laws, regulations and treaty provisions are also subject to various interpretations, and the relevant tax authorities or the courts could later disagree
with the explanations or conclusions set out below.

At the date hereof, there is no Bermuda income, corporation or profits
tax, withholding tax, capital gains tax, capital transfer tax, estate duty or inheritance tax payable by us or our shareholders other than shareholders ordinarily resident in Bermuda. We are not subject to stamp or other similar duty on the
issuance, transfer or redemption of our common shares.

We have obtained an assurance from the Minister of Finance of Bermuda
under the Exempted Undertakings Tax Protection Act 1966 that, in the event there is enacted in Bermuda any legislation imposing tax computed on profits or income or computed on any capital assets, gain or appreciation, or any tax in the nature of
estate duty or inheritance tax, such tax shall not be applicable to us or to our operations, or to the common shares, debentures or our other obligations until March 28, 2016, except insofar as such tax applies to persons ordinarily resident in
Bermuda and holding such common shares, debentures or our other obligations or any real property or leasehold interests in Bermuda owned by us. No reciprocal income tax treaty affecting us exists between Bermuda and the United States.

As an exempted company, we are liable to pay in Bermuda an annual government fee calculated on a sliding scale basis by reference to our
assessable capital, which is the aggregate of our authorized common share capital and the premium on our issued common shares currently at a rate not exceeding US$31,120 per annum.

United States Federal Income Tax Consequences

The discussion below is for general information only and is not, and should not be interpreted to be, tax advice to any holder of our
common shares. Each holder or a prospective holder of our common shares is urged to consult his, her or its own tax advisor.

General

This section is a general summary of the material United States federal income tax consequences to U.S. Holders, as defined below, of the ownership and disposition of our common shares as of the date of
this report. This summary is based on the provisions of the Internal Revenue Code of 1986, as amended, or the Code, the applicable Treasury regulations promulgated and proposed thereunder, judicial decisions and current administrative rulings and
practice, all of which are subject to change, possibly on a retroactive basis. The summary applies to you only if you hold our common shares as a capital asset within the meaning of Section 1221 of the Code. The United States Internal Revenue
Service, or the IRS, may challenge the tax consequences described below, and we have not requested, nor will we request, a ruling from the IRS or an opinion of counsel with respect to the United States federal income tax consequences of acquiring,
holding or disposing of our common shares. This summary does not purport to be a comprehensive description of all the tax considerations that may be relevant to the ownership of our common shares. In particular, the discussion below does not cover
tax consequences that depend upon your particular tax circumstances nor does it cover any state, local or foreign law, or the possible application of the United States federal estate or gift tax. You are urged to consult your own tax advisors
regarding the application of the United States federal income tax laws to your particular situation as well as any state, local, foreign and United States federal estate and gift tax consequences of the ownership and disposition of the common
shares. In addition, this summary does not take into account any special United States federal income tax rules that apply to a particular U.S. or Non-U.S. Holder of our common shares, including, without limitation, the following:



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



| |  |  | a trader in securities that elects to use a market-to-market method of accounting for its securities holdings;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | a financial institution or a bank;
| | - |  | ----------------------------------



| |  |  | an insurance company;
| | - |  | ---------------------

| |  |  | a person that holds our common shares in a hedging transaction or as part of a straddle or a conversion transaction;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | a person whose functional currency for United States federal income tax purposes is not the U.S. dollar;
| | - |  | --------------------------------------------------------------------------------------------------------



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



| |  |  | a person that owns, or is treated as owning, 10% or more, by voting power or value, of our common shares;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | certain former U.S. citizens and residents who have expatriated; or
| | - |  | -------------------------------------------------------------------



| |  |  | a person that receives our shares pursuant to the exercise of employee stock options or otherwise as compensation.
| | - |  | ------------------------------------------------------------------------------------------------------------------

U.S. Holders

For purposes of the discussion below, you are a U.S. Holder if you are a beneficial owner of our common shares who or that is:



| |  |  | an individual United States citizen or resident alien of the United States (as specifically defined for United States federal income tax purposes);
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a corporation, or other entity treated as a corporation for United States federal income tax purposes, created or organized in or under the laws of the
United States, any State or the District of Columbia;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

| |  |  | a trust (x) if a United States court can exercise primary supervision over the trusts administration and one or more United States persons
are authorized to control all substantial decisions of the trust or (y) if it was in existence on August 20, 1996, was treated as a United States person prior to that date and has a valid election in effect under applicable Treasury
regulations to be treated as a United States person.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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

Distributions

Subject to the passive foreign investment company (PFIC) rules discussed below, for cash dividends, the gross
amount of any such distribution (other than in liquidation) that you receive with respect to our common shares generally will be taxed to you as dividend income to the extent such distribution does not exceed our current or accumulated earnings and
profits (E&P), as calculated for U.S. federal income tax purposes. Such income will be includable in your gross income as ordinary income on the date of receipt. Dividends received by individuals and certain other non-corporate
taxpayers from qualified foreign corporations are taxed at the rate of either 0 percent, 15 percent or 20 percent, depending upon the particular taxpayers U.S. federal income tax bracket; provided that the recipient-shareholder has
held his or her shares as a beneficial owner for more than 60 days during the 121-day period beginning on the date which is 60 days before the shares ex-dividend date. A foreign corporation is a qualified foreign corporation if the
stock with respect to which it pays dividends is traded on an established securities market in the United States, provided that the foreign corporation is not a PFIC. Our stock is traded on an established securities market in the United States,
although we cannot guarantee that our stock will be so traded in the future. We believe that we should not be treated as a PFIC for U.S. federal income tax purposes. No assurance can be given, however, that the IRS may not disagree and seek to treat
us as a PFIC. If we were a PFIC with respect to a particular U.S. Holder, dividends received from us will be taxed at regular ordinary income tax rates and certain other rules will apply. See Passive Foreign Investment Company (PFIC),
below. Holders of our shares should consult their own tax advisers regarding the availability of a reduced dividend tax rate in light of their own particular circumstances.

Certain U.S. Holders that are individuals, estates or trusts will be required to pay an additional 3.8 percent tax on net investment income, including interest, dividends, and capital gain. U.S. Holders
should consult their tax advisors as to the application of this additional tax.

To the extent any distribution exceeds our
E&P, the distribution will first be treated as a tax-free return of capital to the extent of your adjusted tax basis in our common shares and will be applied against and reduce such basis on a dollar-for-dollar basis (thereby increasing the
amount of gain and decreasing the amount of loss recognized on a subsequent disposition of such shares). To the extent that such distribution exceeds your adjusted tax basis, the distribution will be taxed as gain recognized on a sale or exchange of
our common shares. See Sale, Exchange or Other Disposition of Our Common Shares, below. Because we are not a U.S. corporation, no dividends-received deduction will be allowed to corporations with respect to dividends paid by us.

For United States foreign tax credit limitation purposes, dividends received on our common shares will be treated as foreign
source income and will generally be passive category income, or in the case of certain holders, general category income. You may be eligible, subject to a number of complex limitations, to claim a foreign tax credit in
respect of foreign tax withholding, if any, imposed on dividends paid on our common shares. The rules governing United States foreign tax credits are complex, and we recommend that you consult your tax advisor regarding the applicability of such
rules to you.

Sale, Exchange or Other Disposition of Our Common Shares

Subject to the PFIC rules discussed below, generally, in connection with the sale, exchange or other taxable disposition of our common
shares:



| |  |  | you will recognize capital gain or loss equal to the difference (if any) between:
| | - |  | ---------------------------------------------------------------------------------



| |  |  | the amount realized on such sale, exchange or other taxable disposition and
| | - |  | ---------------------------------------------------------------------------



| |  |  | your adjusted tax basis in such common shares (your adjusted tax basis in the shares you hold generally will equal your U.S. dollar cost of such
shares);
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | such gain or loss will be long-term capital gain or loss if your holding period for our common shares is more than one year at the time of such sale or
other disposition;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | such gain or loss will generally be treated as United States source for United States foreign tax credit purposes; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | your ability to deduct capital losses is subject to limitations.
| | - |  | ----------------------------------------------------------------

Long-term capital gains recognized by individuals and certain other non-corporate taxpayers, are taxed at the rate of 0, 15 or 20
percent, depending upon the particular taxpayers U.S. federal income tax bracket. Certain U.S. Holders that are individuals, estates or trusts will be required to pay an additional 3.8 percent tax on net investment income, including interest,
dividends, and capital gain. U.S. Holders should consult their tax advisors as to the application of this additional tax.

Passive Foreign Investment Company (PFIC)

We believe that our common shares should not be treated as stock of a PFIC for United States federal income tax purposes, but this
conclusion is a legal and factual determination that is made annually and thus may be subject to change. If we were treated as a PFIC, unless a U.S. Holder elects to be taxed annually on a mark-to-market basis with respect to the shares, gain
realized on the sale or other disposition of your common shares would in general not be treated as capital gain. Instead, you would be treated as if you had realized such gain ratably over your holding period for the common shares. The amounts
allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for such
year, together with an interest charge in respect of the tax attributable to each such year. With certain exceptions, your common shares will be treated as stock in a PFIC if we were a PFIC at any time during your holding period in your common
shares. Dividends that you receive from us will not be eligible for the special tax rates applicable to qualified dividend income if we are treated as a PFIC with respect to you either in the taxable year of the distribution or the preceding taxable
year, but instead will be taxable at rates applicable to ordinary income. Further, any distribution in respect of our common shares in excess of 125 percent of the average annual distributions on our common shares received by you during the
preceding three years or your holding period, whichever is shorter, would be allocated ratably over your holding period for the common shares and subject to taxation as described for sales or other dispositions above.

Non-U.S. Holders

If you are not a U.S. Holder, you are a Non-U.S. Holder.

Distributions on Our Common Shares

You generally will not be subject to U.S. federal income tax or withholding on distributions made on our common shares unless:



| |  |  | you conduct a trade or business in the United States and
| | - |  | --------------------------------------------------------



| |  |  | the distributions are effectively connected with the conduct of that trade or business (and, if an applicable income tax treaty so requires as a
condition for you to be subject to U.S. federal income tax on a profit for the year basis in respect of income from our common shares, such distributions are attributable to a permanent establishment that you maintain in the United States).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If you meet the two tests above, you generally will be subject to tax in respect of such dividends in the
same manner as a U.S. Holder, as described above. In addition, any effectively connected dividends received by a non-U.S. corporation may also, under certain circumstances, be subject to an additional branch profits tax at a 30 percent
rate or such lower rate as may be specified by an applicable income tax treaty.

Sale, Exchange or Other Disposition of Our
Common Shares

Generally, you will not be subject to U.S. federal income tax or withholding in respect of gain recognized
on a sale or other disposition of our common shares unless:



| |  |  | your gain is effectively connected with a trade or business that you conduct in the United States (and, if an applicable income tax treaty so requires
as a condition for you to be subject to U.S. federal income tax on a profit for the year basis in respect of gain from the sale or other disposition of our common shares, such gain is attributable to a permanent establishment maintained by you in
the United States), or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | you are an individual Non-U.S. Holder and are present in the United States for at least 183 days in the taxable year of the sale or other disposition,
and certain other conditions exist.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

You will be subject to tax in respect of any gain effectively connected
with your conduct of a trade or business in the United States generally in the same manner as a U.S. Holder, as described above. Effectively connected gains realized by a non-U.S. corporation may also, under certain circumstances, be subject to an
additional branch profits tax at a rate of 30 percent or such lower rate as may be specified by an applicable income tax treaty.

Backup Withholding and Information Reporting

Payments, including dividends
and proceeds of sales, in respect of our common shares that are made in the United States or by a United States related financial intermediary will be subject to United States information reporting rules. In addition, such payments may be subject to
United States federal backup withholding. You will not be subject to backup withholding provided that:



| |  |  | you are a corporation or other exempt recipient, or
| | - |  | ---------------------------------------------------



| |  |  | you provide your correct United States federal taxpayer identification number and certify, under penalties of perjury, that you are not subject to
backup withholding.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------

Amounts withheld under the backup withholding rules may be credited against your United
States federal income tax, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the IRS in a timely manner.

Documents on Display

We are subject to the information requirements of the Securities Exchange Act of 1934, as amended. In accordance with these requirements, we file reports and other information with the SEC. These
materials may be inspected and copied at the Commissions Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549. The public may obtain information on the operation of the Commissions Public Reference Room by

the Commission.



|Item 11. | Quantitative and Qualitative Disclosure about Market Risk
|-------- | ---------------------------------------------------------

Market Risks

Our exposure to financial market risks relates primarily to
changes in interest rates and foreign exchange rates. To mitigate these risks, we utilize derivative financial instruments, the application of which is primarily for hedging, and not for speculative, purposes.

Interest Rate Risks

As of December 31, 2014, we had aggregate debts outstanding of NT$7,836 million (US$248 million), which was incurred for capital expenditure and general operating expenses. Of our outstanding debts
as of December 31, 2014, 100% bear interest at variable rates. The interest rate for the majority of our variable rate debts varies based on a fixed percentage spread over the prime rate established by our lenders. Our variable rate debts had
an annual weighted average interest rate of 1.708% as of December 31, 2014. Accordingly, we have cash flows and earnings exposure due to market interest rate changes for our variable rate debts. An increase in interest rates of 1% would
increase our annual interest charge by NT$78 million (US$2 million) based on our outstanding floating rate indebtedness as of December 31, 2014.

As of December 31, 2013 and 2014, we had no interest rate swap agreements outstanding.

Foreign Currency Exchange Rate Risks

Our foreign currency exposure gives
rise to market risks associated with exchange rate movements against the NT dollar, the Japanese yen and the US dollar. As of December 31, 2014, 31.2% of our financial assets and 27.3% of our financial liabilities are denominated in the US
dollar and Japanese yen, respectively. We do not hold or issue any derivative for trading purposes or to hedge against fluctuations in foreign exchange rates. We mitigate this risk by conducting sales and purchases transactions in the same currency.
These hedging transactions help to reduce, but do not eliminate, the impact of foreign currency exchange rate movements. An average appreciation of the NT dollar against all other relevant foreign currencies of 5% would decrease our exchange gain by
NT$159 million (US$5 million) based on our outstanding assets and liabilities denominated in foreign currencies as of December 31, 2014. As of December 31, 2013 and 2014, we had no outstanding forward exchange or foreign currency option
contracts.

See Note 30 of our audited consolidated financial statements for additional information on financial risk
management.

Disclosure Controls and Procedures. An evaluation was carried out under the supervision and with the participation of our
management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended). Based upon that

Managements Report on Internal Control Over Financial Reporting

April 24, 2015

Management of ChipMOS TECHNOLOGIES (Bermuda) LTD. (together
with its consolidated subsidiaries, the Company) is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended). The
Companys internal control over financial reporting is a process designed under the supervision of the Companys chief executive officer and chief financial officer to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of the Companys financial statements for external reporting purposes in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

As of December 31, 2014, the Companys management, with the participation of the Companys chief executive officer and
chief financial officer, conducted an assessment of the effectiveness of the Companys internal control over financial reporting using criteria set forth in Internal Control  Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, the Companys management has concluded that the Companys internal control over financial reporting as of December 31, 2014 was effective.

Moore Stephens CPA Limited, an independent registered public accounting firm, has audited our consolidated financial
statements included in the Annual Report of the Company on Form 20-F for the year ended December 31, 2014 and has issued an attestation report on the Companys internal control over financial reporting as of December 31, 2014. The
attestation report is set forth in Item 18. Financial Statements.

Not applicable.



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

Our corporate governance practices are governed by applicable Bermuda law, specifically, the Bermuda Companies Act, and our memorandum of association and bye-laws. Also, because our securities are listed
on the NASDAQ, we are subject to corporate governance requirements applicable to NASDAQ-listed foreign private issuers under NASDAQ listing rules.

Under NASDAQ Rule 5615(a)(3), NASDAQ-listed foreign private issuers may, in general, follow their home country corporate governance practices instead of most NASDAQ corporate governance requirements.
However, all NASDAQ-listed, foreign private issuers must comply with NASDAQ Rules 5605(c)(2)(A)(ii), 5605(c)(3), 5625 and 5640.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

ChipMOS TECHNOLOGIES (Bermuda) LTD.

We have
audited the accompanying consolidated statements of financial position of ChipMOS TECHNOLOGIES (Bermuda) LTD. and subsidiaries (collectively, the Group) as of December 31, 2013 and 2014, and the related consolidated income
statements, statements of comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2014. We have also audited the Groups internal control over financial reporting as of
December 31, 2014, based on criteria established in Internal Control  Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Group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 the accompanying Managements Report on
Internal Control Over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Groups internal control over financial reporting based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we
plan and perform the audits to obtain reasonable assurance about whether the consolidated 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 consolidated 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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could
have a material effect on the financial statements.

Because of 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.

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

ChipMOS TECHNOLOGIES (Bermuda) LTD. (the Company or ChipMOS Bermuda) was incorporated under the laws of Bermuda on August 1, 2000, and its common shares have been traded on
the NASDAQ Global Market since June 2001 and traded on the NASDAQ Global Select Market since July 1, 2006. In February 2010, ChipMOS Bermuda submitted an application to the NASDAQ Stock Market to transfer its listing to the NASDAQ Capital Market
from the NASDAQ Global Select Market. The NASDAQ Stock Market has determined that the Company meets the NASDAQ Capital Market initial listing criteria set forth in Listing Rule 5505. Its common shares have been traded on the NASDAQ Capital Market
since March 17, 2010.

On January 21, 2011, the Companys shareholders approved a one-for-four share combination
of its common stock which became effective on January 21, 2011. As a result of this reverse stock split, every four shares of the Companys common stock that were issued and outstanding as of January 21, 2011 were automatically
combined into one issued and outstanding share with par value change from US$0.01 to US$0.04 per share, and the number of authorized but unissued shares of the Companys common stock was proportionally reduced. A proportionate adjustment was
also made to the Companys outstanding stock options and convertible notes. No fractional shares were issued in connection with this reverse stock split, but rather shareholders who were entitled to fractional shares received cash in aggregate
of NT$239 thousand in lieu of receiving fractional shares.

As of December 31, 2014, the consolidated financial statements
of the Company include:

ChipMOS TECHNOLOGIES INC. (ChipMOS Taiwan) was incorporated in Taiwan on
July 28, 1997 as a joint venture company between Mosel Vitelic Inc. and Siliconware Precision Industries Co. Ltd. (SPIL). Its operations consist of testing and assembly of semiconductors. In connection with a corporate restructuring
on January 12, 2001, the holders of an aggregate of 583,419 thousand common shares of ChipMOS Taiwan executed a Purchase and Subscription Agreement whereby they transferred their shares of ChipMOS Taiwan to ChipMOS Bermuda in exchange for
14,585 thousand common shares in ChipMOS Bermuda. The selling shareholders, who previously held an aggregate of 70.25% of the entire outstanding common shares of ChipMOS Taiwan, thus became the holder of the entire outstanding common shares of
ChipMOS Bermuda. Because 100% of the outstanding common shares of ChipMOS Bermuda were owned by former shareholders of ChipMOS Taiwan, the exchange of shares has been accounted for as a merger as if ChipMOS Bermuda was the acquirer. Equity and
operations attributable to ChipMOS Taiwan shareholders not participating in the exchange offer were reflected as non-controlling interests in the historical financial statements. In March 2007, ChipMOS Bermuda, ChipMOS Taiwan and SPIL completed a
share purchase and subscription transaction whereby ChipMOS Bermuda purchased 100% of SPILs equity interest in ChipMOS Taiwan at US$0.75 per share. SPIL also subscribed to 3,043,749 newly issued common shares of ChipMOS Bermuda through a
private placement of US$6.28 per share. After the transaction, ChipMOS Taiwan became a 99.14% subsidiary of ChipMOS Bermuda and SPIL owned 14.7% of ChipMOS Bermuda. In September 2007, another share exchange transaction was completed whereby ChipMOS
Bermuda offered to exchange one share of ChipMOS Bermuda for 8.4 shares of ChipMOS Taiwan shares. The exchange was completed in September 2007 and ChipMOS Taiwan became a wholly-owned subsidiary of ChipMOS Bermuda. In February 2010, ChipMOS Bermuda
entered into a Share Purchase Agreement with SPIL to sell to SPIL the holding of 133,000 thousand common shares of ChipMOS Taiwan for a consideration of NT$1,630,580 thousand. In January 2011, the transaction was completed. As part of ChipMOS
Taiwans listing plan on the Taiwan Stock Exchange (TWSE), on April 16, 2013, ChipMOS Bermuda completed the sale of 6.5 million outstanding ChipMOS Taiwan shares, at the price of NT$15.0 per share to ChipMOS Taiwans
underwriters of the TWSE listing plan and to certain others, including non-US employees of ChipMOS Taiwan. On October 3, 2013, ChipMOS Bermuda completed the sale of 180.0 million outstanding ChipMOS Taiwan shares, at the price of NT$20.0
per share to investors and certain non-US employees of ChipMOS Taiwan. Also on April 9, 2014, ChipMOS Bermuda completed the sale of 1.3 million outstanding ChipMOS Taiwan shares, at the price of NT$26.5 per share as green shoe
option to market investors. As of December 31, 2014, ChipMOS Bermuda owned 60.38% (2013:62.09%) of ChipMOS Taiwans outstanding shares without any green shoe option outstanding.

ThaiLin Semiconductor Corp. (ThaiLin) was incorporated on May 15, 1996 and is listed on the GreTai Securities Market in
Taiwan. ThaiLin is engaged in wafer and semiconductor testing services. On December 31, 2002, ChipMOS Taiwan acquired an equity interest of 41.8% in ThaiLin. On December 1, 2003, ChipMOS Taiwan obtained controlling influence over
ThaiLins decisions on its operations, personnel and financial policies. Therefore, ThaiLin has been consolidated into these financial statements from December 1, 2003 in spite of the fact that ChipMOS Taiwan holds an equity interest of
less than 50% in ThaiLin. As of December 31, 2014, ChipMOS Taiwan held a 47.54% (2013: 47.54%) equity interest in ThaiLin.

ChipMOS U.S.A., Inc. (ChipMOS USA) was incorporated in the United States of America in October 1999. It engages in sales and
customer services and all the expenses incurred from these activities are charged to current income. ChipMOS USA began generating revenue in 2001. As of December 31, 2014, ChipMOS Taiwan owned 100% (2013: 100%) of the outstanding shares of
ChipMOS USA.

MODERN MIND TECHNOLOGY LIMITED (Modern Mind) was incorporated in the British
Virgin Islands on January 29, 2002. Modern Mind conducts its operations through ChipMOS TECHNOLOGIES (Shanghai) LTD. (ChipMOS Shanghai). ChipMOS Shanghai a wholly-owned subsidiary of Modern Mind was established in the Peoples
Republic of China (PRC) on June 7, 2002. ChipMOS Shanghai is engaged in wafer testing, semiconductor assembly and testing, and module and subsystem manufacturing. ChipMOS Shanghai commenced commercial production in 2003. ChipMOS
Bermuda acquired a 100% equity interest in Modern Mind on December 12, 2002, and then transferred it to Jesper Limited (Jesper) on December 31, 2002. In December 2002 and 2003, ChipMOS Bermuda acquired from Jesper and ChipMOS
Taiwan, respectively, convertible notes issued by Modern Mind (MMT Notes) that are convertible into a controlling equity interest in Modern Mind if the repayment is not made when due. Under an Assignment and Assumption Agreement signed
on April 22, 2011, ChipMOS Bermuda agreed to sell the MMT Notes to ThaiLin for a purchase price US$39,950 thousand. On October 3, 2011, the transaction was completed. On October 3, 2011, ThaiLin converted the MMT Notes into common
shares of Modern Mind and purchased all of the remaining common shares of Modern Mind from Jesper. Modern Mind and its wholly-owned subsidiary, ChipMOS Shanghai, became wholly-owned subsidiaries of ThaiLin. ChipMOS Bermudas interest in ChipMOS
Shanghai was reduced to 36.11% then. Prior to October 3, 2011, ChipMOS Bermuda consolidated Modern Mind and its wholly-owned subsidiary, ChipMOS Shanghai in reliance on International Accounting Standard 27 (Revised) Consolidated and
Separate Financial Statements. ChipMOS Bermuda had a parent-subsidiary relationship with Modern Mind by means other than record ownership of voting stock. This relationship was based on ChipMOS Bermudas power to direct or cause the
direction of the management and policies of Modern Mind and ChipMOS Shanghai. As of December 31, 2014, ThaiLin owned 100% (2013: 100%) of the outstanding shares of Modern Mind and Modern Mind owned 100% (2013: 100%) of the interests of ChipMOS
Shanghai.



|2. | Basis of preparation of financial statements and principal accounting policies
|-- | ------------------------------------------------------------------------------



| | a) | Basis of preparation
| | -- | --------------------

These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRSs), which collective term includes all applicable individual
IFRSs, International Accounting Standards (IASs) issued by the International Accounting Standards Board (IASB) and Interpretations issued by the International Financial Reporting Interpretations Committee (IFRIC)
of the IASB.

These consolidated financial statements have been prepared under the historical cost convention except for
accrued pension cost which has been measured at fair value. These consolidated financial statements are presented in New Taiwan dollars (NT$), which is the Companys functional currency.



| | b) | Adoption of new and revised International Financial Reporting Standards
| | -- | -----------------------------------------------------------------------

In the preparation of the financial statements for the year ended December 31, 2014, the Group has applied, for the first time, the
following revised standards and a new interpretation issued by the IASB.



| |  |                                                  |  |

|2. | Basis of preparation of financial statements and principal accounting policies (continued)
|-- | ------------------------------------------------------------------------------------------



| | b) | Adoption of new and revised International Financial Reporting Standards (continued)
| | -- | -----------------------------------------------------------------------------------



The adoption of the above revised standards and interpretation has had no significant
effect on these consolidated financial statements.



| | c) | Basis of consolidation
| | -- | ----------------------

The consolidated financial statements include the accounts of ChipMOS Bermuda and all entities controlled by ChipMOS Bermuda. The financial statements of subsidiaries are prepared for the same reporting
period as the Company, using consistent accounting policies. The results of subsidiaries are consolidated from the date on which the Group obtains control, and continue to be consolidated until the date that such control ceases.

Profit or loss and each component of other comprehensive income are attributed to the owners of the parent of the Group and to the
non-controlling interests, even if this results in the non-controlling interests having a deficit balance. All intra-group transactions, balances, income and expenses are eliminated in full on consolidation.

The Group reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of
the three elements of control described in the accounting policy for subsidiaries below. A change in the ownership interest of a subsidiary, without loss of control, is accounted for as an equity transaction.

The Companys consolidated financial statements for the years ended December 31, 2012, 2013 and 2014 include the financial
results of ChipMOS Taiwan and its subsidiaries, ThaiLin, ChipMOS USA, Modern Mind and ChipMOS Shanghai.

Changes in the
Groups ownership interests in subsidiaries that do not result in the Group losing control over the subsidiaries are accounted for as equity transactions. The carrying amounts of the Groups interests and the non-controlling interests are
adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in
equity and attributed to owners of the Company.

When the Group loses control of a subsidiary, the profit or loss on disposal
is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any investment retained and (ii) the previous carrying amount of the assets (including goodwill), and
liabilities of the subsidiary and any non-controlling interests. The Groups share of components previously recognized in other comprehensive income is reclassified to income statements or retained profits, as appropriate, on the same basis as
would be required if the Group had directly disposed of the related assets or liabilities.

| | d) | Significant judgments and estimates
| | -- | -----------------------------------

The preparation of consolidated financial statements requires management to make judgments, estimates and assumptions that affect the recorded amounts of assets, liabilities, revenue and expenses of the
Group. The Group continually evaluates these estimates, including those related to share-based payments, impairment of receivables, impairment of non-financial assets, depreciation of property, plant and equipment, defined benefit plans, deferred
tax assets and deferred tax liabilities. The Group bases its estimates on historical experience and other assumptions, which it believes to be reasonable under the circumstances. Actual results may differ from these estimates under different
assumptions and conditions.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting
estimates are recognized in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

Management has considered the development, selection and disclosure of the Groups critical accounting policies and estimates.

Judgments

In the process of applying the Groups accounting policies, management has made the following judgments which have the most significant effect on the amounts recognized in the consolidated financial
statements:

Entities in which the Group holds less than 50% of the voting rights

ChipMOS Bermuda consolidated ThaiLin in reliance on IFRS 10 Consolidated Financial Statements which requires a company to
consolidate an entity, notwithstanding the lack of majority ownership, if such consolidation is necessary to present fairly its financial position and results of operations because of the existence of a parent-subsidiary relationship by means other
than record ownership and by means other than record ownership of voting stock. This relationship is based on ChipMOS Bermudas power to direct or cause the direction of the management and policies of ThaiLin.

Estimates and assumptions

The key assumptions concerning the future and other key sources of estimation uncertainty at the end of the reporting period, that have a significant risk of causing a material adjustment to the carrying
amounts of assets and liabilities within the next financial year are discussed below.

Share-based payments

The Group measures the cost of equity-settled transactions with employees by reference to the fair value of the equity instruments at the
date at which they are granted. Estimating fair value for share-based payments requires determining the most appropriate valuation model for a grant of equity instruments, which is dependent on the terms and conditions of the grant. This also
requires determining the most appropriate inputs to the valuation model including the expected life of the option, volatility and dividend yield and making assumptions about them.

The assumptions and models used for estimating fair value for share-based payments are disclosed in Note 31.

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



Estimates and assumptions (continued)



Impairment of receivables

Receivables are assessed for indicators of impairment at the end of each reporting period, and are impaired where there is objective
evidence that, as a result of one or more events that occurred after the initial recognition of the receivables, the estimated future cash flows of the receivables have been impacted. For the customer that we have reason to believe may have an
inability to meet its financial obligations, we conduct an individual examination based on the available facts and circumstances to record a specific reserve. For the customers other than this, a general reserve is established based on a range of
percentages applied to aging categories. These percentages are based on historical collection and write-off experience. If circumstances change, the estimate of the recoverability of amounts due to us could be reduced by a material amount. Further
details are disclosed in Note 16.

Impairment of non-financial assets

Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its
fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arms length, for similar assets or observable market prices less
incremental costs for disposing of the asset. The value in use calculation is based on a discounted cash flow (DCF) model. The cash flows are derived from the budget for the next five years and do not include restructuring activities
that the Group is not yet committed to or significant future investments that will enhance the assets performance of the cash generating unit being tested. The recoverable amount is sensitive to the discount rate used for the DCF model as well
as the expected future cash-inflows and the growth rate used for the extrapolation purposes. Further details are disclosed in Note 13.

Depreciation of property, plant and equipment

Property, plant and
equipment are depreciated on a straight-line basis over their estimated economic useful lives. The determination of the useful lives involves managements estimation. The Group assesses annually the useful life of the property, plant and
equipment and if the expectation differs from the original estimate, such a difference may impact the depreciation in the year when the estimate is changed and the future period.

Defined benefit plans

The cost of the defined benefit pension plan and post-employment benefits and the present value of the pension obligation are determined using actuarial valuations. An actuarial valuation involves making
various assumptions that may differ from actual developments in the future. These include the determination of the discount rate, future salary increases, mortality rates and future pension increases. Due to the complexities involved in the
valuation and its long-term nature, a defined benefit obligation is highly sensitive to changes in these assumptions. All assumptions are reviewed at each reporting date. Further details are disclosed in Note 22.

Deferred tax assets

Deferred tax assets are recognized for unused tax losses and tax credit to the extent that it is probable that taxable profit will be available against which the losses can be utilized. Significant
management judgment is required to determine that amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable profits together with future tax planning strategies.

Estimates and assumptions (continued)



Deferred tax assets (continued)

The Group has NT$915,012 thousand (US$28,956 thousand) (2013: NT$1,218,080 thousand) of tax losses carried forward. These losses relate to
subsidiaries that have a history of losses and may not be used to offset taxable income elsewhere in the Group. The subsidiaries neither have any taxable temporary difference nor any tax planning opportunities available that could partly support the
recognition of these losses as deferred tax assets. On this basis, the Group has determined that it cannot recognize deferred tax assets on the tax losses carried forward.

Deferred tax liabilities

In the opinion of the directors, the Company
controls the dividend policy of its subsidiaries in the Republic of China (ROC) and it is probable that the temporary differences arising from the withholding tax on dividends declared in respect of the profits earned by the
Companys subsidiaries in the ROC will not reverse in the foreseeable future.

Further details on deferred taxes are
disclosed in Note 9.



| | e) | Property, plant and equipment and depreciation
| | -- | ----------------------------------------------

Property, plant and equipment are stated at cost, less provision for depreciation and impairment losses, if any.

The cost of an item of property, plant and equipment comprises its purchase price and any directly attributable cost of bringing the asset to its working condition and location for its intended use.
Expenditure incurred after the item has been put into operation, such as repairs and maintenance and overhaul costs, is normally charged to the consolidated income statements in the year in which it is incurred. In situations where it can be clearly
demonstrated that the expenditure has resulted in an increase in future economic benefits expected to be obtained from the use of the item, the expenditure is capitalized as an additional cost of the item. When an item of property, plant and
equipment is sold, its cost and accumulated depreciation are removed from the financial statements and any gain or loss resulting from the disposal, being the difference between the net disposal proceeds and the carrying amount of the asset, is
included in consolidated income statements.

Depreciation is provided on the straight-line method, based on the estimated
economic useful life of the individual assets, as follows:



|                                  |  |  |               | 
|--------------------------------- |  |  | ------------- | 
|Buildings and auxiliary equipment |  |  | 1 to 54 years | 
|Machinery and equipment           |  |  | 1 to 6 years  | 
|Tools                             |  |  | 1 to 5 years  | 
|Other equipment                   |  |  | 1 to 7 years  | 

Where parts of an item of property, plant and equipment have different useful lives, the cost of that item
is allocated on a reasonable basis among the parts and each part is depreciated separately. Residual values, useful lives and the depreciation method are reviewed, and adjusted if appropriate, at least at each financial year end.

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



| | e) | Property, plant and equipment and depreciation (continued)
| | -- | ----------------------------------------------------------



An item of property, plant and equipment including any significant part initially
recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss on disposal or retirement recognized in the consolidated income statements in the year the asset is derecognized is
the difference between the net sales proceeds and the carrying amount of the relevant asset.



| | f) | Impairment of non-financial assets
| | -- | ----------------------------------

Where an indication of impairment exists, or when periodical impairment testing for an asset is required (other than inventories, deferred tax assets and financial assets), the recoverable amount of the
asset is estimated. An assets recoverable amount is the higher of the value in use of the asset or cash-generating unit to which it belongs and its fair value less costs to sell, and is determined for an individual asset, unless the asset does
not generate cash inflows that are largely independent of those from other assets or groups of assets, in which case the recoverable amount is determined for the cash-generating unit to which the asset belongs.

An impairment loss is recognized only if the carrying amount of an asset exceeds its recoverable amount. In assessing value in use, the
estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. An impairment loss is charged to the
consolidated income statements in the period in which it arises in those expense categories consistent with the function of the impaired asset.

An assessment is made at the end of each reporting period as to whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased. If such indication
exists, the recoverable amount is estimated. A previously recognized impairment loss of an asset is reversed only if there has been a change in the estimates used to determine the recoverable amount of that asset, but not to an amount higher than
the carrying amount that would have been determined (net of any depreciation), had no impairment loss been recognized for the asset in prior years. A reversal of such impairment loss is credited to the consolidated income statements in the period in
which it arises.



| | g) | Inventories
| | -- | -----------

Inventories are stated at the lower of cost and net realizable value. Cost is determined on a weighted average cost basis and includes all
costs of purchase, costs of conversion, and other costs incurred in bringing the inventories to their present location and condition.

Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

When inventories are sold, the carrying amount of those inventories is recognized as an expense in the period in which the related revenue
is recognized. The amount of any write-down of inventories to net realizable value and all losses of inventories are recognized as an expense in the period the write-down or loss occurs. The amount of any reversal of any write-down of inventories is
recognized as a reduction in the amount of inventories recognized as an expense in the period in which the reversal occurs.

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



| | h) | Investments and other financial assets
| | -- | --------------------------------------

Initial recognition and measurement

The Groups financial assets are
classified, at initial recognition, into financial assets at fair value through profit or loss (FVTPL), loans and receivables, held-to-maturity investments and available-for-sale financial investments. When financial assets are
recognised initially, they are measured at fair value plus transaction costs that are attributable to the acquisition of the financial assets.

All regular way purchases or sales of financial assets are recognized on the trade date, that is, the date that the Group commits to purchase or sell the asset. Regular way purchases or sales are
purchases or sales of financial assets that require delivery of assets within the time frame established by regulation or convention in the marketplace.

Effective interest method

The effective interest method is a method of
calculating the amortized cost of a debt instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts (including all fees on points paid or
received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the debt instrument, or, where appropriate, a shorter period.

Income is recognized on an effective interest basis for debt instruments.

Subsequent measurement

The subsequent measurement of financial assets depends on their classification as follows:

Financial assets at fair value through profit or loss

Financial assets at
FVTPL include financial assets held for trading and those designated as at FVTPL upon initial recognition.

A financial asset
is classified as held for trading if it has been acquired principally for the purpose of selling in the near future; or it is a part of an identified portfolio of financial instruments that the Group manages together and has a recent actual pattern
of short-term profit-taking; or it is a derivative that is not designated and effective as a hedging instrument.

A financial
asset other than a financial asset held for trading may be designated as at FVTPL upon initial recognition if:



| |  |  | such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | the financial asset forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on
fair value basis, in accordance with the Groups documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | it forms part of a contract containing one or more embedded derivatives, and IAS 39 Financial Instruments: Recognition and Measurement
permits the entire combined contract (asset or liability) to be designated as at FVTPL.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There were no
financial assets at FVTPL at the end of the reporting periods.

| | h) | Investments and other financial assets (continued)
| | -- | --------------------------------------------------



Subsequent measurement (continued)



Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. At
the end of each reporting period, subsequent to initial recognition, loans and receivables (including accounts and notes receivables, other receivables, short-term deposits and cash and cash equivalents) are carried at amortized cost using the
effective interest method, less any identified impairment losses.

Available-for-sale financial investments

Available-for-sale financial investments are non-derivative financial assets in unlisted equity investments. Equity investments classified
as available for sale are those which are neither classified as held for trading nor designated as at fair value through profit or loss.

When the fair value of unlisted equity investments cannot be reliably measured because (a) the variability in the range of reasonable fair value estimates is significant for that investment or
(b) the probabilities of the various estimates within the range cannot be reasonably assessed and used in estimating fair value, such investments are stated at cost less any impairment losses.

The Group evaluates whether the ability and intention to sell its available-for-sale financial investments in the near term are still
appropriate. When, in rare circumstances, the Group is unable to trade these financial assets due to inactive markets, the group may elect to reclassify these financial assets if management has the ability and intention to hold the assets for the
foreseeable future or until maturity.



| | i) | Impairment of financial assets
| | -- | ------------------------------

The Group 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. An impairment exists if one or more events
that occurred after the initial recognition of the asset have an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be reliably estimated. Evidence of impairment may include indications that a
debtor or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganisation and observable data indicating
that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults.

Financial assets carried at amortised cost

For financial assets carried at
amortised cost, the Group first assesses whether impairment exists individually for financial assets that are individually significant, or collectively for financial assets that are not individually significant. If the Group determines that no
objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, it includes the asset in a group of financial assets with similar credit risk characteristics and collectively assesses them for
impairment. Assets that are individually assessed for impairment and for which an impairment loss is, or continues to be, recognized are not included in a collective assessment of impairment.

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



| | i) | Impairment of financial assets (continued)
| | -- | ------------------------------------------



Financial assets carried at amortised cost (continued)



The amount of any impairment loss identified is measured as the difference between the
assets carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not yet been incurred). The present value of the estimated future cash flows is discounted at the financial assets
original effective interest rate (i.e., the effective interest rate computed at initial recognition). The carrying amount of the asset is reduced through the use of an allowance account and the loss is recognized in the consolidated income
statement. Interest income continues to be accrued on the reduced carrying amount and is accrued using the rate of interest used to discount the future cash flows for the purpose of measuring the impairment loss. Loans and receivables together with
any associated allowance are written off when there is no realistic prospect of future recovery and all collateral has been realised or has been transferred to the Group.

If, in a subsequent period, the amount of the estimated impairment loss increases or decreases because of an event occurring after the impairment was recognized, the previously recognized impairment loss
is increased or reduced by adjusting the allowance account. If a write-off is later recovered, the recovery is credited to other expenses in the consolidated income statement.



| | j) | Derecognition of financial assets
| | -- | ---------------------------------

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e., removed from the Groups consolidated statement
of financial position) when:



| |  |  | the rights to receive cash flows from the asset have expired; or
| | - |  | ----------------------------------------------------------------



| |  |  | the Group has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without
material delay to a third party under a pass-through arrangement; and either (a) the Group has transferred substantially all the risks and rewards of the asset, or (b) the Group has neither transferred nor retained
substantially all the risks and rewards of the asset, but has transferred control of the asset.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

When the
Group has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent it has retained the risk and rewards of ownership of the asset. When it has neither transferred
nor retained substantially all the risks and rewards of the asset nor transferred control of the asset, the Group continues to recognize the transferred asset to the extent of the Groups continuing involvement. In that case, the Group also
recognises an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained.

Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying
amount of the asset and the maximum amount of consideration that the Group could be required to repay.

| | k) | Financial liabilities
| | -- | ---------------------

Initial recognition and measurement

Financial liabilities are classified,
at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings, net of directly attributable
transaction costs.

The Groups financial liabilities include bank loans, accounts payable and other monetary liabilities.

Subsequent measurement

The subsequent measurement of financial liabilities depends on their classification as follows:

Loans and borrowings

After initial recognition, interest-bearing loans and
borrowings are subsequently measured at amortised cost, using the effective interest rate method unless the effect of discounting would be immaterial, in which case they are stated at cost. Gains and losses are recognized in the consolidated income
statements when the liabilities are derecognized as well as through the effective interest rate amortisation process.

Amortised cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of
the effective interest rate. The effective interest rate amortisation is included in finance costs in the consolidated income statements.



| | l) | Derecognition of financial liabilities
| | -- | --------------------------------------

A financial liability is derecognised when the obligation under the liability is discharged or cancelled, or expires. When an existing financial liability is replaced by another from the same lender on
substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and a recognition of a new liability, and the difference
between the respective carrying amounts is recognised in the consolidated income statements.



| | m) | Dividends
| | -- | ---------

Dividends are simultaneously proposed and declared, because the Companys Bye Laws grant the directors the authority to declare
dividends. Consequently, dividends are recognized immediately as a liability when they are proposed and declared.



| | n) | Operating lease charges
| | -- | -----------------------

Where the Group has the use of assets held under operating leases, payments made under the leases are charged to the consolidated income statements in equal installments over the accounting periods
covered by the lease term, except where an alternative basis is more representative of the pattern of benefits to be derived from the leased assets. Lease incentives received are recognized in the consolidated income statements as an integral part
of the aggregate net lease payments made. Contingent rentals, if any, are charged to the consolidated income statements in the accounting period in which they are incurred.

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



| | o) | Treasury stock
| | -- | --------------

Treasury stock is stated at cost and shown as a deduction in equity. When the Company retires treasury stock, the treasury stock account
is reduced and the share capital as well as the capital surplus  share premium are reversed on a pro rata basis. When the book value of the treasury stock exceeds the sum of par value and share premium, the difference is charged to capital
surplus and to retained earnings for any remaining amount. The Companys stock held by its subsidiary is treated as treasury stock.



| | p) | Provisions
| | -- | ----------

A
provision is recognized when a present obligation (legal or constructive) has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation, provided that a reliable estimate can
be made of the amount of the obligation.

When the effect of discounting is material, the amount recognized for a provision is
the present value at the end of the reporting period of the future expenditures expected to be required to settle the obligation. The increase in the discounted present value amount arising from the passage of time is included in finance costs in
the consolidated income statements.



| | q) | Foreign currency translation
| | -- | ----------------------------

The consolidated financial statements are presented in New Taiwan dollars, which is the Companys functional currency. Each entity in the Group determines its own functional currency and items
included in the financial statements of each entity are measured using that functional currency. Foreign currency transactions are initially recorded using the functional currency rates ruling at the date of the transactions. Monetary assets and
liabilities denominated in foreign currencies are retranslated at the functional currency rates of exchange ruling at the end of the reporting period. All differences are taken to profit or loss. Non-monetary items that are measured in terms of
historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair
value was determined. The functional currencies of certain overseas subsidiaries are currencies other than the New Taiwan dollars. As at the end of the reporting period, the assets and liabilities of these entities are translated into the
presentation currency of the Company at the exchange rates ruling at the end of the reporting period, and their income and expense items are translated into New Taiwan dollars at the weighted average exchange rates for the year.

The resulting exchange differences are recorded in other comprehensive income and the cumulative balance is included in exchange reserve
in the consolidated statements of changes in equity. On disposal of a foreign entity, the deferred cumulative amount recognized in exchange reserve relating to that particular foreign operation is recognized in the consolidated income statements.
For the purpose of the consolidated statements of cash flows, the cash flows of overseas subsidiaries are translated into New Taiwan dollars at the exchange rates ruling at the dates of the cash flows. Frequently recurring cash flows of overseas
subsidiaries which arise throughout the year are translated into New Taiwan dollars at the weighted average exchange rates for the year.

| | r) | Revenue recognition
| | -- | -------------------

Revenue is recognized to the extent that it is probable that the economic benefits arising in the course of business will flow to the
Group and the revenue can be reliably measured, regardless of when the payment is being made. Revenue is measured at the fair value of the consideration received or receivable, taking into account contractually defined terms of payment and excluding
taxes or duty.

Rendering of services

The Group recognized revenue upon completion of testing and assembly services. Other criteria that the Group uses to determine when to recognize revenue are: (1) existence of persuasive evidence of
the services provided, (2) customers fixed commitment to use our service, (3) the selling price is fixed or determinable and (4) collectability is reasonably measured.

The Group does not take ownership of: (1) bare semiconductor wafers received from customers that are assembled into finished
semiconductors, and (2) assembled semiconductors received from the customers that it tests. The title and risk of loss remains with the customer for those bare semiconductors and/or assembled semiconductors. Accordingly, the customer-supplied
semiconductor materials are not included in the consolidated financial statements.

The Group does not provide warranties to
customers except in cases of defects in the assembly services provided and deficiencies in testing services provided. An appropriate sales allowance is recognized in the period during which the sale is recognized, and is estimated based on
historical experience.

Interest income

Interest income is recognized on an accrual basis using the effective interest method by applying the rate that discounts the estimated future cash receipts through the expected life of the financial
instrument to the net carrying amount of the financial asset.



| | s) | Government grant
| | -- | ----------------

The grant relates to land use rights in the PRC. Government grants are recognised at their fair value where there is reasonable assurance
that the grant will be received and all attaching conditions will be complied with. When the grant relates to an expense item, it is recognised as income on a systematic basis over the periods that the costs, which it is intended to compensate, are
expensed.

Where the grant relates to an asset, the fair value is credited to a deferred income account and is released to the
consolidated income statement over the expected useful life of the relevant asset by equal annual installments or deducted from the carrying amount of the asset and released to the consolidated income statement by way of a reduced depreciation
charge.

Where the Group receives grants of non-monetary assets, the grants are recorded at the fair value of the non-monetary
assets and released to the consolidated income statements over the expected useful lives of the relevant assets by equal annual installments.



| | t) | Research and development costs
| | -- | ------------------------------

Research and development costs are expensed in the period in which it is incurred.

| | u) | Borrowing costs
| | -- | ---------------

Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that
necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale. All other borrowing costs are
charged to the consolidated income statements in the period in which they are incurred.



| | v) | Pension and other post-employment benefits
| | -- | ------------------------------------------

The Group operates defined contribution and defined benefit plans in the ROC and the PRC. For defined contribution retirement benefit plans, payments to the benefit plan are recognized as an expense when
the employees have rendered service entitling them to the contribution. For defined benefit retirement plans, the cost of providing benefit is recognized based on actuarial calculations.

For defined benefit retirement benefit plans, the cost of providing benefits is determined using the Projected Unit Credit Method, with
actuarial valuations being carried out at the year end. Actuarial gains and losses are recognized in other comprehensive income in the period which they incur. Past service costs are recognized in the consolidated income statements on the earlier of
the date of the plan amendment or curtailment, and the date that the Group recognizes restructuring-related costs. Net interest is calculated by applying the discount rate to the net defined benefit liability or asset. The Group recognizes the
changes in the net defined benefit obligation, including i) service costs comprising current service costs, past service costs, gains and losses on curtailments and non-routine settlements, and ii) net interest expense or income, under cost of
revenue, research and development expenses, sales and marketing expenses and administrative and general expenses in the consolidated income statements.

The employees of the subsidiary within the Group which operates in the PRC are required to participate in the central pension scheme operated by the local municipal government. The PRC subsidiary is
required to contribute a percentage of its payroll costs to the central pension scheme as specified by the local municipal government.

Employee entitlements to annual leave are recognized when they accrue to employees. An accrual is made for the estimated liability for annual leave as a result of services rendered by employees up to the
end of the reporting period.



| | w) | Share-based payments
| | -- | --------------------

Employees of the Group receive remuneration in the form of share-based payments, whereby employees render services as consideration for equity instruments (equity-settled transactions) or share
appreciation rights, which are settled in cash (cash-settled transactions).

| | w) | Share-based payments (continued)
| | -- | --------------------------------



Equity-settled transactions

The cost of equity-settled transactions is determined by the fair value at the date when the grant is made using an appropriate valuation
model.

That cost is recognized, together with a corresponding increase in capital surplus in equity, over the period in which
the performance and/or service conditions are fulfilled in employee benefits expense. The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has
expired and the Groups best estimate of the number of equity instruments that will ultimately vest.

When the terms of an
equity-settled award are modified, as a minimum, the services received measured at the grant date fair value of the equity instruments granted should be recognized, unless those equity instruments do not vest because of failure to satisfy a vesting
condition (other than a market condition) that was specified at grant date. An additional expense is recognized for any modification that increases the total fair value of the share-based payment transaction, or is otherwise beneficial to the
employee as measured at the date of modification.

Where an equity-settled award is cancelled, it is treated as if it had
vested on the date of cancellation, and any expense not yet recognized for the award is recognized immediately. This includes any award where non-vesting conditions within the control of either the Group or the employee are not met. However, if a
new award is substituted for the cancelled award, and is designated as a replacement award on the date that it is granted, the cancelled and new awards are treated as if they were a modification of the original award, as described in the previous
paragraph.

Cash-settled transactions

The cost of cash-settled transactions is measured initially at fair value at the grant date using an appropriate valuation model. This fair value is expensed over the period until the vesting date with
recognition of a corresponding liability. The liability is re-measured to fair value at each reporting date up to, and including the settlement date, with changes in fair value recognized in employee benefits expense.



| | x) | Income tax
| | -- | ----------

Income
tax represents the sum of current and deferred tax. Income tax relating to items recognized outside profit or loss is recognized outside profit or loss, either in other comprehensive income or directly in equity.

Current tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities, based on
tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period, taking into consideration interpretations and practices prevailing in the countries in which the Group operates.

Deferred tax is provided, using the liability method, on all temporary differences at the end of the reporting period between the tax
bases of assets and liabilities and their carrying amounts for financial reporting purposes.

| | x) | Income tax (continued)
| | -- | ----------------------



Deferred tax liabilities are recognised for all taxable temporary differences, except:



| |  |  | when the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business
combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in respect of taxable temporary differences associated with investments in subsidiaries, associates and joint ventures, when the timing of the reversal
of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Deferred tax assets are recognized for all deductible temporary differences, the carryforward of unused tax credits and any unused tax losses. Deferred tax assets are recognised to the extent that it is
probable that taxable profits will be available against which deductible temporary differences, the carryforward of unused tax credits and unused tax losses can be utilised, except:



| |  |  | when the deferred tax asset relating to the deductible temporary differences arises from the initial recognition of an asset or liability in a
transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in respect of deductible temporary differences associated with investments in subsidiaries, associates and joint ventures, deferred tax assets are only
recognised to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilised.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no longer
probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilised. Unrecognised deferred tax assets are reassessed at the end of each reporting period and are recognised to the extent that it has
become probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be recovered.

Deferred tax is calculated, without discounting, at the tax rates that are expected to apply in the period when the asset is realised or
the liability is settled, based on the tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period.

Deferred tax assets and liabilities are offset when they relate to income taxes levied by the same taxation authority and the Group intends to settle its current tax assets and liabilities on a net basis.

| | y) | Cash and cash equivalents
| | -- | -------------------------

Cash and cash equivalents comprise cash on hand and demand deposits, and short-term highly liquid investments which are readily convertible into known amounts of cash, are subject to an insignificant risk
of changes in value, and have a short maturity of generally within three months when acquired.



| | z) | Related parties
| | -- | ---------------



| | (a) | A person, or a close member of that persons family, is related to the Group if that person:
| | --- | --------------------------------------------------------------------------------------------



| | (i) | has control or joint control over the Group;
| | --- | --------------------------------------------



| | (ii) | has significant influence over the Group; or
| | ---- | --------------------------------------------



| | (iii) | is a member of key management personnel of the Group or the Groups parent.
| | ----- | ---------------------------------------------------------------------------

or



| | (b) | An entity is related to the Group if any of the following conditions applies:
| | --- | -----------------------------------------------------------------------------



| | (i) | The entity and the Group are members of the same group.
| | --- | -------------------------------------------------------



| | (ii) | One entity is an associate or joint venture of the other entity (or an associate or joint venture of a member of a group of which the other entity is a member).
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | The entity and the Group are joint ventures of the same third party.

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



| | aa) | Subsidiaries
| | --- | ------------

A
subsidiary is an entity (including a structured entity) controlled by the Company. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns
through its power over the investee (i.e., existing rights that give the Group the current ability to direct the relevant activities of the investee).

When the Company has, directly or indirectly, less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has
power over an investee, including:



| |  |  | the contractual arrangement with the other vote holders of the investee;
| | - |  | ------------------------------------------------------------------------



| |  |  | rights arising from other contractual arrangements; and
| | - |  | -------------------------------------------------------



| |  |  | the Groups voting rights and potential voting rights.

| | bb) | Fair value measurement
| | --- | ----------------------

The Group measures its accrued pension cost at fair value at the end of each reporting period. Fair value is 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. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either in the principal market for the asset or
liability, or in the absence of a principal market, in the most advantageous market for the asset or liability. The principal or the most advantageous market must be accessible by the Group. The fair value of an asset or a liability is measured
using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest.

A fair value measurement of a non-financial asset takes into account a market participants ability to generate economic benefits by using the asset in its highest and best use or by selling it to
another market participant that would use the asset in its highest and best use.

The Group uses valuation techniques that are
appropriate in the circumstances and for which sufficient data are available to measure fair value, maximising the use of relevant observable inputs and minimising the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorised within the fair value
hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1  based on quoted prices (unadjusted) in active markets for identical assets or liabilities

Level 2  based on valuation techniques for which the lowest level input that is significant to the fair value measurement is
observable, either directly or indirectly

Level 3  based on valuation techniques for which the lowest level input that
is significant to the fair value measurement is unobservable

For assets and liabilities that are recognized in the financial
statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by reassessing categorisation (based on the lowest level input that is significant to the fair value measurement as a whole) at the
end of each reporting period.



|3. | Translation into U.S. dollar amounts
|-- | ------------------------------------

The Company maintains its accounts and expresses its consolidated financial statements in New Taiwan dollars. For convenience purposes, U.S. dollar amounts presented in the accompanying consolidated
financial statements have been translated from New Taiwan dollars to U.S. dollars at the noon buying rate in the City of New York for cable transfers as certified for customs purposes by the Federal Reserve Bank of New York as of December 31,
2014, which was NT$31.60 to US$1.00. These convenience translations should not be construed as representations that the New Taiwan dollar amounts have been, or could in the future be, converted into U.S. dollars at this or any other rate of
exchange.

At December 31, 2014, the Group has tax losses arising in the PRC of approximately NT$915,012
thousand (US$28,956 thousand) (2013: NT$1,218,080 thousand) that are available for offsetting against future taxable profits of the Group companies in which the losses arose and will expire after five years if not fully utilized by the Group.
Deferred tax assets have not been recognized in respect of these losses as it is not considered probable that taxable profits will be available against which these tax losses can be utilized.

As of December 31, 2014, the temporary differences associated with withholding tax on dividends from the Companys subsidiaries
in the ROC not recognized as deferred tax liabilities amounted to NT$3,003,336 thousand (US$95,042 thousand) (2013: NT$2,169,473 thousand).

|10. | Earnings per share (EPS)
|--- | --------------------------

Basic EPS amounts are calculated by dividing the profit for the year attributable to equity holders of the Company by the weighted average number of ordinary shares outstanding during the year.

Diluted EPS amounts are calculated by dividing the profit attributable to equity holders of the Company by the weighted
average number of ordinary shares outstanding during the year plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares.

The following reflects the income and share data used in the basic and diluted EPS computations:

Receivables that were neither past due nor impaired relate to a large number of diversified customers for
whom there was no recent history of default.

Receivables that were past due but not impaired relate to a number of independent
customers that have a good track record with the Group. Based on past experience, the management of the Company are of the opinion that no provision for impairment is necessary in respect of these balances as there has not been a significant change
in credit quality and the balances are still considered fully recoverable.

|22. | Accrued pension cost
|--- | --------------------



| | a) | Defined benefit plans
| | -- | ---------------------



| | 1) | ChipMOS Taiwan and ThaiLin have defined benefit plans that provide benefits based on an employees length of service and average monthly salary for the six-month
period prior to retirement. The aforementioned companies contribute an amount equal to 2% of salaries paid each month to their respective pension funds (Funds), which are deposited in the Labor Pension Fund Supervisory Committees
name in Bank of Taiwan. The Labor Pension Fund Supervisory Committee shall review, supervise, and audit all matters related to the Labor Pension Fund.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The plan provides benefits that are defined by salary and period of membership and hence, the benefits do not bear a direct relationship with the assets supporting them. The plan is a final salary defined
benefit plan and is a compulsory pension plan for eligible employees in accordance with the Taiwans Labor Standards Law. Plan benefits are paid in the form of lump sum.

The plan assets are 100% held in a commingled fund which is operated and managed by the government designated authorities. The Group does not have any rights to intervene in the funds investment.

Contingencies arising from a legal claim



| | a. | On April 1, 1999, Motorola, Inc. (Motorola) and ChipMOS Taiwan entered into an immunity agreement (the Agreement), that each party
covenanted not to sue each other for the use of certain Ball Grid Array (BGA) patents pursuant to the Agreement. In December 2004, Motorola spun off its semiconductor division and thereby formed Freescale Semiconductor, Inc.
(Freescale). Subsequently, Freescale assumed Motorolas rights and obligations under the Agreement. On July 13, 2009, Freescale filed a complaint with the court alleging that ChipMOS Taiwan breached the Agreement by failing to
pay royalties on certain BGA packages assembled by ChipMOS Taiwan. ChipMOS Taiwan filed an answer to deny all allegations and also filed counterclaims against Freescale and for declaratory judgement of patent non-infringement and invalidity. After
procedures of numerous motions, discovery, summary judgment and mediation, on June 20, 2013, both parties reached a settlement agreement to settle the pending litigation in a judicial settlement conference conducted in Court. As part of the
settlement agreement, ChipMOS Taiwan agreed to pay US$8,000 thousand to settle the claims in exchange for the parties entering into a new License Agreement for the use of Freescales BGA packaging technology from 2011 to 2015 by a royalty fee
of US$1,000 thousand per year and filing a Joint Stipulation for the Dismissal of all claims pending between them. After settlement, ChipMOS Taiwan reserved the over-accrued royalty of NT$140,435 thousand (Note 6) to other operating income. The
Joint Stipulation for Dismissal was filed on July 26, 2013 and the case was closed by the Court.

| | b. | On April 20, 1999, ChipMOS Taiwan entered into a semiconductor packaging technology license agreement with Tessera Technologies, Inc. (Tessera). In
February 2006, ChipMOS Taiwan and ChipMOS USA received notice of a patent infringement lawsuit brought by Tessera, alleging infringement of several Tessera patents and breach of an existing license agreement with ChipMOS Taiwan. On April 21,
2008, Tessera requested that the International Trade Commission investigate ChipMOS Bermuda, ChipMOS Taiwan and ChipMOS USA on the basis of alleged violations of Section 337 of the Tariff Act of 1930. After procedures of numerous motions,
discovery and mediation, on November 8, 2013, the parties reached a settlement agreement to settle the pending litigation. As part of the settlement agreement, ChipMOS Taiwan agreed to pay a one-time payment of US$1,375 thousand, including 20%
Taiwan tax withholding, to Tessera in exchange for Tessera releasing, discharging and agreeing to never sue ChipMOS Bermuda, ChipMOS Taiwan and ChipMOS USA relating to the license agreement. On November 9, 2013, the parties filed a stipulation
with the Court to dismiss the pending litigation and the case was closed by the Court.

| | 1) | Market risk
| | -- | -----------

Market risk is the
risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risks comprise foreign currency risk, interest rate risk, and other price risk (such as equity price risk).



| | i) | Foreign currency risk
| | -- | ---------------------

Foreign
currency risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in foreign exchange rates. The Groups exposure to the risk of changes in foreign exchange rate relates primarily to the
Groups operating activities (when revenue or expense is denominated in a different currency from the Groups functional currency) and the Groups net investments in foreign subsidiaries. The currencies giving rise to this risk are
primarily United States dollars (US$) and Japanese Yen (JPY). The Group does not hold or issue any derivative for trading purposes or to hedge against fluctuations in foreign exchange rates. The Group mitigates this risk by
conducting sales and purchases transactions in the same currency, whenever possible. Furthermore, as net investments in foreign subsidiaries are for strategic purpose, they are not hedged by the Group.

The following table details the Groups exposure at the end of the reporting period to currency risk arising from recognized
monetary assets or liabilities denominated in a currency other than the functional currency of the entity to which they relate.

| | a) | Financial risk management (continued)
| | -- | -------------------------------------



| | 1) | Market risk (continued)
| | -- | -----------------------





| | ii) | Interest rate risk
| | --- | ------------------

Interest
rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Groups exposure to the risk of changes in market interest rates relates primarily to the
Groups bank loans with floating interest rates.

The Group manages its interest rate risk by having a balanced portfolio
of fixed and variable rate bank loans.

At December 31, 2014, it is estimated that a general increase or decrease of 100
basis points (1%) in interest rates, with all other variables held constant, would decrease or increase the Groups profit and equity by approximately NT$78,364 thousand (US$ 2,480 thousand) (2013: NT$75,504 thousand).



| | iii) | Equity price risk
| | ---- | -----------------

The Group is
exposed to equity price risk through its investments in listed equity securities classified as financial assets at fair value through profit or loss. The Group manages this exposure by maintaining a portfolio of investments with different risk and
return profiles. At the reporting date, no aforesaid equity security was held and no sensitivity analysis was disclosed.



| | 2) | Credit risk
| | -- | -----------

Credit risk is the
risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. The Group is exposed to credit risk from its operating activities (primarily accounts and other receivables) and
from its financing activities (primarily deposits with banks and financial instruments).

Each business unit performs ongoing
credit evaluation of the debtors financial condition according to the Groups established policy, procedures and control relating to customer credit risk management. The Group maintains an account for allowance for doubtful receivables
based upon the available facts and circumstances, historical collection and write-off experiences of all trade and other receivables which consequently minimizes the Groups exposure to bad debts.

The Group has three customers that had balances greater than ten percent of total notes and accounts receivable as of December 31,
2013 and 2014, respectively, as detailed in the below table. The credit concentration risk of other accounts and notes receivable is insignificant.



|                         |  |                  |                |  |                  |  |     |

|Customers                |  | December 31,2013 |                |  | December 31,2014 | 
|Micron                   |  |                  | 13%            |  |                  |  | 14% | 
|Novatek                  |  |                  | 17%            |  |                  |  | 18% | 
|Himax Technologies, Inc. |  |                  | Not applicable |  |                  |  | 10% | 

Credit risk from balances with banks and financial institutions is managed by the Groups finance
unit in accordance with the Groups policy. Bank balances are held with financial institutions of good standing. The Groups exposure to credit risk arising from the default of counter-parties is limited to the carrying amount of these
instruments.

| | 3) | Liquidity risk
| | -- | --------------

Liquidity risk
is the risk that the Group will encounter difficulty in raising funds to meet commitments associated with financial instruments. The Group monitors and maintains adequate cash and banking facilities to finance the Groups operations. See Notes
21 and 23 about the unused credit lines of the Group.

The maturity profile of the Groups non-derivative financial
liabilities as of December 31, 2013 and 2014 based on the contracted undiscounted payments, is as follows:

|32. | Capital management
|--- | ------------------

The Group manages its capital to ensure that entities in the Group will be able to continue as a going concern while maximizing the return
to shareholders through the optimization of the balance between debt and equity.

The capital structure of the Group consists
of debt, which includes bank loans of NT$7,836,423 thousand (US$247,988 thousand) (2013: NT$7,550,408 thousand) (Notes 21 and 23) less cash and cash equivalents of NT$15,265,153 thousand (US$483,074 thousand) (2013: NT$13,372,770 thousand) (Note
17), and equity attributable to equity holders of the Company, comprising issued capital of NT$34,019 thousand (US$1,077 thousand) (2013:NT$37,165 thousand) and all other equity reserves attributable to the equity holders of the Company of
NT$14,582,746 thousand (US$461,479 thousand) (2013: NT$13,527,498 thousand) disclosed in the consolidated statements of changes in equity.

The Group reviews the capital structure on an ongoing basis. As part of this review, the directors consider the cost of capital and the risks associated with each class of capital. The Group will balance
its overall capital structure through the payment of dividends, new share issues and the issue of new debt or the repayment of existing debt.

The Groups overall strategy remains unchanged from 2013.

The Group monitors
capital using the net debt-to-equity ratio, the percentages of which as of December 31, 2013 and 2014 were as follows:

The Group has already commenced an assessment of the related impact of adopting the above new and revised IFRSs.
So far, it has concluded that the above new and revised IFRSs will be adopted at the respective effective dates and the adoption of them is unlikely to have a significant impact on the consolidated financial statements of the Group except for the
following:

IFRS 9 Financial Instruments

In September 2014, the IASB issued the final version of IFRS 9, bringing together all phases of the financial instruments project to
replace IAS 39 and all previous versions of IFRS 9. The standard introduces new requirements for classification and measurement, impairment and hedge accounting. The Group expects to adopt IFRS 9 from January 1, 2018. The Group expects that the
adoption of IFRS 9 will have an impact on the classification and measurement of the Groups financial assets. Further information about the impact will be available nearer the implementation date of the standard.

IFRS 15 Revenue from Contracts with Customers

IFRS 15 establishes a new five-step model that will apply to revenue arising from contracts with customers. Under IFRS 15, revenue is recognized at an amount that reflects the consideration to which an
entity expects to be entitled in exchange for transferring goods or services to a customer. The principles in IFRS 15 provide a more structured approach for measuring and recognising revenue. The standard also introduces extensive qualitative and
quantitative disclosure requirements, including disaggregation of total revenue, information about performance obligations, changes in contract asset and liability account balances between periods and key judgements and estimates. The standard will
supersede all current revenue recognition requirements under IFRSs. The Group expects to adopt IFRS 15 on January 1, 2017 and is currently assessing the impact of IFRS 15 upon adoption.

Annual Improvements to IFRSs 2012-2014 Cycle

The Annual Improvements to IFRSs 2012-2014 Cycle issued in September 2014 sets out amendments to a number of IFRSs. The Group expects to adopt the amendments from 1 January 2016. None of the amendments
are expected to have a significant financial impact on the Group. Details of the amendments are as follows:

IFRS 5
Non-current Assets Held for Sale and Discontinued Operations:Clarifies that changes to a plan of sale or a plan of distribution to owners should not be considered to be a new plan of disposal, rather it is a continuation of the
original plan. Accordingly, there is no change in the application of the requirements in IFRS 5. The amendment also clarifies that changing the disposal method does not change the date of classification of the non-current assets or disposal group
held for sale. The amendment is to be applied prospectively.

IFRS 7 Financial Instruments: Disclosures:Clarifies that a servicing contract that includes a fee can constitute continuing involvement in a financial asset. An entity must assess the nature of the fee and arrangement against the guidance for continuing involvement in IFRS 7 in order to
assess whether the IFRS 7 disclosures are required.

IAS 19 Employee Benefits: Clarifies that market depth of
high quality corporate bonds used for discounting the post-employment benefit obligation for defined benefit plans is assessed based on the currency in which the obligation is denominated, rather than the country where the obligation is located.
When there is no deep market for high quality corporate bonds in that currency, government bond rates must be used.
