Forward Looking Statements in This Annual Report May Not Be Accurate

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

	•		the intensely competitive semiconductor and personal computer industries and markets;

	•		risks associated with international business activities;

	•		our dependence on key personnel;

	•		natural disasters, such as earthquakes and droughts, which are beyond our control;

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

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

	•		fluctuations in foreign currency exchange rates;

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

	•		those other risks identified in “Item 3. Key Information—D. Risk Factors” of this annual report.

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

(1)		Prior to January 1, 2005, the ROC Securities and Futures Bureau allowed us to delay our recognition of investment income or loss in certain investee companies accounted for under the equity method until the following accounting year. As a result, in 2002, we delayed the recognition of investment loss of NT$366 million in relation to the financial results of ChipMOS Technology Inc., or ChipMOS, until 2003. In addition, in 2003 and 2004, we delayed the recognition of investment income of NT$247 million and NT$668 million, respectively, in relation to the financial results of ChipMOS, until 2004 and 2005, respectively, and recorded the above-mentioned amount of NT$668 million as cumulative effects of changes in accounting principles in 2005. From January 1, 2005, we adopted ROC Statement of Financial Accounting Standards No. 5, “Accounting for Long-term Equity Investment”, pursuant to which we ceased to defer the recognition of investment income or loss of investees accounted for under the equity method until the subsequent year, and recognized investment income or loss from all investees accounted for under the equity method based on investees’ audited financial statements for the same periods. We recognized investment income of NT$433 million and NT$1,125 million for the years ended December 31, 2005 and 2006, respectively, and NT$246 million (US$7.6 million) for the period between January 1, 2007 and March 27, 2007 from ChipMOS’s financial results. In 2005, 2006 and 2007, our investment income under US GAAP from ChipMOS were NT$469 million, NT$1,045 million and NT$253 million (US$7.8 million), respectively.


		Pursuant to a Share Purchase and Subscription Agreement entered into among us, ChipMOS Technologies (Bermuda) Ltd., or ChipMOS Bermuda and ChipMOS, on March 27, 2007, we sold, and ChipMOS Bermuda and ChipMOS purchased, all of the common shares of ChipMOS, at par value NT$10 per share, owned by us for a total cash consideration of US$191,147,464. In addition, we subscribed for 12,174,998 newly issued common shares of ChipMOS Bermuda, at par value US$0.01 per share, for an aggregate consideration of US$76,458,987, representing a purchase price of US$6.28 per common share of ChipMOS Bermuda. Upon the completion of the transaction, we owned 14.7% of ChipMOS Bermuda. From the date of the completion of the sale and purchase, we are required under both ROC GAAP and US GAAP to recognize our ownership in ChipMOS Bermuda as available-for-sale financial assets and evaluate their fair market value on a quarterly basis (under ROC GAAP) and on an annual basis (under US GAAP) and reflect any difference in evaluation from the previous quarter as an addition in or a deduction from “unrealized gain or loss on available-for-sale financial assets”.

We also experienced a delay in recognition of investment income in Double Win Enterprise Co., Ltd., or Double Win, in 2003 and 2004 and Taiwan Hi-tech, or Taiwan Hi-Tech, in 2003, and recognized their financial results in the subsequent year. Our investment income (loss) from Double Win and Taiwan Hi-tech for the aforementioned years was not material. Under US GAAP, there is no provision that allows us to delay recognition of financial results of ChipMOS or any other investee accounted for under the equity method.


(2)		We did not have minority interest in 2003, 2004, 2005, 2006 or 2007. Therefore, no such information is presented separately in this table.

(3)		Retroactively adjusted for all subsequent stock dividends and employee share bonuses.

(4)		Adjusted to reflect 210,497,278 shares, 187,655,305 shares, 267,794,338 shares and 93,876,060 shares distributed as stock dividends and employee stock bonuses in 2004, 2005, 2006 and 2007, respectively, with respect to the earnings of 2003, 2004, 2005 and 2006. No stock dividend was declared in 2003.

(5)		Retroactively adjusted for all subsequent stock dividends only.

(6)		Amounts translated for convenience at the Federal Reserve Bank of New York noon buying exchange rate of NT$32.43 to US$1.00 on December 31, 2007.

Subsequent to the filing of our consolidated financial statements on Form 20-F for the year ended December 31, 2004, we determined that our accounting for the derivative instruments, embedded in our convertible bonds, was incorrect. The accounting for such embedded derivatives is described in note 33 to our financial statements included elsewhere in this annual report. We have corrected our US GAAP reconciliation for the years ended December 31, 2003 and 2004 accordingly.

Currency Translations and Exchange Rates

We have translated certain New Taiwan dollars, or NT dollars, amounts included in this annual report into US dollars for the convenience of the readers. The rate we used for the translations was NT$32.43 = US$1.00, which was the noon buying rate announced by the Federal Reserve Bank of New York on December 31, 2007. The translation does not mean that NT dollars could actually be converted into US dollars at that rate. The following table shows the noon buying rates for NT dollars expressed in NT dollar per US$1.00.

Not applicable.

C. Reasons for the Offer and Use of Proceeds

Not applicable.

D. Risk Factors

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

Risks Relating to Our Financial Condition and Business

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

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

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

	•		changes in our mix of manufacturing services or our customers’ preferences. When we discontinue or add manufacturing service or when our customers’ demand change, our operating results usually fluctuate.

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

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

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

Because our manufacturing services are, and will continue to be, dependent on the requirements of semiconductor companies for independent testing and assembly services, any downturn in the highly cyclical semiconductor industry, caused by economic downturns or other reasons, may reduce demand for our manufacturing services and adversely affect our results of operations. Variations in order levels from our customers and in service fee rates may result in volatility in our net operating revenues and earnings. The markets for semiconductors are also

characterized by rapid technological change, evolving industry standards and periods of heightened competition. If demand for semiconductor capacity does not keep pace with the growth of supply, or further declines, our manufacturing services would be subject to more intense competition and our results of operations may suffer because of the resulting downward pricing pressure and capacity underutilization. Any increased competition may cause average selling prices of many of our semiconductor packages and testing services to decrease significantly, which may lead to pressure on our gross margins and negatively affect our operating results. Future downturns in the semiconductor industry may be severe. In the event of any future downturn, our average selling prices may decline without a corresponding decrease in our high fixed costs. This could lead to a decline in our gross margin, which would seriously harm our manufacturing services.

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

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

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

From 2004 to 2007, we have maintained relatively high capacity utilization rates due to relatively high demand for our manufacturing services. We cannot assure you that we will be able to achieve or sustain a high utilization rate in the future. Nor can we assure you that declines in the semiconductor industry or other factors will not harm our capacity utilization or our profitability in the future.

Given the high fixed costs of our services, high capacity utilization allows us to maintain higher gross margins because it allows us to allocate fixed costs over a greater number of units we package and test. Increases or decreases in capacity utilization rates can have a significant effect on our manufacturing services. Accordingly, our ability to enhance our gross margins will depend, in part, on our ability to continue to increase our capacity utilization rates.

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

	•		ensure that our packaging and testing technologies meet our customers’ needs;

	•		install advanced equipment in anticipation of new business; and

	•		prevent disruption of operations due to fire, accidents, mechanical and technical failures, expansion, introduction of new packages or relocation of equipment.

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

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

We are dependent on a small group of customers for a substantial portion of our manufacturing services. In 2005, 2006 and 2007, 62.6%, 62.8% and 61.0% of our net operating revenues, respectively, were derived from sales to our top ten customers. In 2007, our largest and second largest customers accounted for 10.6% and 10.2%, respectively, of our net operating revenues. We expect that we will continue to depend on a relatively limited number of customers for a significant portion of our net operating revenues because of the concentration of demand in the semiconductor industry for our manufacturing services. Our ability to maintain close and satisfactory relationships with our customers is important to the ongoing success and profitability of our manufacturing services. Few of our customers are presently obligated to purchase packaging or testing services or to provide us with binding forecasts of product purchases for any period. If any of our significant customers reduces, delays or cancels its orders to a significant degree, our manufacturing services would be harmed because each of these customers accounts for a significant portion of our net operating revenues.

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

We have engaged in equipment and facilities expansion in recent years to upgrade our technology and equipment. Our business growth in the future will continue to require substantial capital expenditures to fund such equipment and facilities expansions. The growing demand for our manufacturing services has and will continue to require significant capital expenditures on substrate packaging technology and equipment. In making these planned capital expenditures, we may need to obtain additional capital. In addition, we may be unable to accurately estimate the timing and amount of our capital requirements, which depend on a number of factors, including demand for our manufacturing services and availability of equipment and whether or when the market will recover. In addition, we cannot assure you that additional financing will be available on satisfactory terms to us, or at all, when we require additional financing. If we are unable to obtain the necessary capital resources or financing, we will not be able to achieve our future business growth.

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

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

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

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

If demand for the services of Taiwan’s wafer foundries decreases, a significant source of our sales would decrease, which would seriously harm our business

We largely depend on Taiwan’s independent wafer foundries to source our sales orders. In recent years, a significant portion of our net operating revenues were derived from packaging and testing semiconductor wafers manufactured at Taiwan’s wafer foundries. If the demand for foundry services offered by Taiwan’s wafer foundries decreases for any reason, including shifts in demand for these services to wafer foundries in other countries, an important source of our sales would be lost and our profitability would suffer.

If we are unable to obtain raw materials from our suppliers, our production schedules would be delayed and we may lose customers

We must obtain sufficient quantities of raw materials at acceptable prices in a timely manner. We source most of our raw materials, including critical materials like substrates and lead-frames, 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 or limited the supply of required materials to us because of supply capacity constraints during market upturns for the semiconductor industry. Consequently, we have experienced from time to time difficulty in obtaining acceptable quantities of raw materials on a timely basis. In addition, from time to time, we may reject materials that do not meet our specifications, resulting in declines in output or yield. We cannot assure you that we will be able to obtain in the future sufficient quantities of raw materials and other supplies of an acceptable quality. Our inability to obtain raw materials in a timely and cost effective manner would cause us to delay our production and delivery schedules, which may result in the loss of our customers and revenues.

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

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

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

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

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

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

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

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

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

The semiconductor packaging and testing processes require the use of chemicals and gases which are regulated by the government. For example, liquid waste is produced when silicon wafers are diced into chips using diamond saws and cooled with running water. Liquid waste is also produced when lead-frames are plated onto wafer chips and cleansed with water. Moreover, excess material on leads and moldings are removed from packaged semiconductors in the trim and form process. Environmental claims or the failure to comply with any environmental regulations could result in damages or fines against us or suspension of production. We may be required by new regulations to acquire costly equipment or to incur other significant expenses. If we fail to control the use of hazardous substances, we could incur future liabilities, including clean up costs.

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

Our operations and those of our customers and suppliers are particularly vulnerable to fires, earthquakes, typhoons, droughts, floods, power losses, and similar events. We cannot guarantee that future earthquakes will not cause material damage to our facilities or property, including work in progress, or cause significant business interruptions. Although we maintain property and business interruption insurance for such risks, there is no guarantee that future damages or business loss from earthquakes will be covered by such insurance, that we will be able to collect from our insurance carriers, should we choose to claim under our insurance policies, or that such coverage will be sufficient.

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

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

A substantial portion of our net operating revenues is derived from sales to customers located outside of Taiwan. In 2005, 2006 and 2007, sales to our overseas customers accounted for 62.0%, 64.1% and 64.6%, respectively, of our net operating revenues. We expect sales to customers outside of Taiwan to continue to represent a significant portion of our net operating revenues. As a result, our manufacturing services will continue to be vulnerable to disruptions in the international trading environment, including adverse changes in foreign government regulations, political unrest and international economic downturns.

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

The differences between Taiwan and U.S. accounting standards resulted in different amounts of our net income under those standards, which makes evaluating our financial performance difficult

Our financial statements are prepared under ROC GAAP, which differ in many respects from US GAAP. Year-to-year comparison of our financial results under ROC GAAP may significantly differ from year-to-year comparison under US GAAP. Largely as a result of the differences in accounting for employee bonuses and overseas convertible bonds, our net income in 2005, 2006 and 2007 under US GAAP was NT$3,971 million, NT$8,413 million and NT$13,099 million (US$403.9 million), respectively, as compared to net income under ROC GAAP of NT$8,244 million, NT$13,329 million and NT$17,489 million (US$539.3 million), respectively.

Under ROC GAAP, our overseas convertible bonds are recorded as a liability at an amount equal to the proceeds received. Any discount or premium to the par value of the overseas convertible bonds is amortized in the statement of operations by using the effective interest rate. No bifurcation for embedded derivatives is required for convertible bonds issued before January 1, 2006, on which the ROC SFAS No. 34 took effect. However, under US GAAP, in accordance with SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities”, our overseas convertible bonds issued in 2002 and 2004, with the feature of the combination of mutually exclusive conversion of the debt to equity or redemption at a multiple of the bonds par value, are required to be accounted for as embedded derivative instruments. The embedded derivatives separated from the book value of bonds are measured at fair value and changes in fair value are recognized as unrealized gain (loss) in the income statement for each accounting period.

Risks Relating to Our Technologies

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

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

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

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

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

	•		the level of contaminants in the manufacturing environment;

	•		human error;

	•		equipment malfunction;

	•		incorrect process condition setting;

	•		use of defective raw materials; and

	•		inadequate sample testing.

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

We rely on technology provided by third parties

We have licensed from Freescale Semiconductor Inc., or Freescale, formerly part of Motorola, Inc., or Motorola, the technology for ball grid array for which we make royalty payments based on the number of pads or balls used in our packages. We also implement new packages by entering into technology alliances and by licensing package technologies from certain technology companies.

There can be no assurance that third parties will continue to license advanced technologies to us on terms satisfactory or acceptable to us after these licensing agreements expire, or at all. In the event that we are unable to license such advanced technologies from the third parties, we may be required to develop designed around technologies internally. There can be no assurance that we will be able to develop such technologies internally.

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

We may suffer legal liabilities and damages if we infringe on the proprietary rights of others or incur costs resulting from legal claims and adverse proceedings against us. Despite this, we have no means of knowing what patent applications have been filed in the United States or elsewhere until they are granted. The semiconductor packaging and testing industry is characterized by frequent litigation regarding patent and other intellectual property rights. If any third party were to make valid intellectual property infringement claims against us or our customers, we could be required to:

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

	•		pay substantial monetary damages;

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

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

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

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

On March 1, 2006, we were informed of a lawsuit brought by Tessera Inc., or Tessera, in the United States District Court for the Northern District of California against us, our subsidiary Siliconware USA, Inc., and five other semiconductor companies and their subsidiaries. Tessera alleges that some of our packaging services have infringed patents owned by Tessera and that we have breached license agreements with Tessera. In May 2007, the parties stipulated a stay pending a final determination of an investigation directed against other parties (including certain co-defendants in the lawsuit) conducted by the U.S. International Trade Commission, or the ITC. Pursuant to the stipulation, the court has stayed the litigation. In February 2007, we filed in the U.S. Patent and Trademark Office, or the PTO, requests for reexamination of five patents, four of which being asserted by Tessera against us. The PTO has

issued office actions in the reexaminations of all patents at issue. We are vigorously defending against Tessera’s allegations. For more information, see “Item 4. Information on the Company — B. Business Overview — Litigation.”

Political and Economic Risks

We face substantial political risks associated with doing business in Taiwan, particularly due to the tense relationship between the ROC and the PRC

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

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

Our shares are listed on the Taiwan Stock Exchange. The trading price of our ADSs may be affected by the trading price of our shares on the Taiwan Stock Exchange. The Taiwan Stock Exchange is a smaller market and, more volatile than the securities markets in the United States and a number of European countries. The Taiwan Stock Exchange has experienced substantial fluctuations in the prices and volumes of sales of listed securities, and there are currently limits on the range of daily price movements on the Taiwan Stock Exchange. During 2007, the Taiwan Stock Exchange Index peaked at 9,809.9 on October 29, 2007, and reached a low of 7,344.6 on March 5, 2007. From January 2, 2007 to December 31, 2007, daily closing values of our shares ranged from NT$47.50 per share to NT$75.80 per share. The Taiwan Stock Exchange is particularly volatile during times of political instability, including when relations between Taiwan and the PRC are strained. Moreover, the Taiwan Stock Exchange has experienced problems including market manipulation, insider trading and settlement defaults. The recurrence of these or similar problems could decrease the market price and liquidity of our shares and ADSs.

The market price of the ADSs may also be affected by general trading activities on the U.S. stock exchanges, which have experienced significant price volatility with respect to shares of technology companies. Fluctuations in interest rates and other general economic conditions, such as recession and economic downturns caused by the sub-prime crisis, high energy costs and other concerns, in Taiwan and other countries where our products are sold may also have an effect on the market price of our ADSs. Daily closing values of our ADSs ranged from US$1.84 to US$12.54 between June 7, 2000, the date our ADSs were listed on NASDAQ National Market, or NASDAQ, and December 31, 2007. Over the same period, the NASDAQ Composite Index ranged from 1,114.11 to 5,048.62.

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

More than half of our net operating revenues are denominated in currencies other than NT dollars, primarily US dollars. On the other hand, more than half of our costs of direct labor, raw materials and overhead are incurred in NT dollars. We are affected by fluctuations in exchange rates among the US dollar, the Japanese Yen, the NT dollar and other currencies. Any significant fluctuation in exchange rates may be harmful to our financial condition. In addition, fluctuations in the exchange rate between the US dollar and the NT dollar will affect the US dollar value of

the ADSs and the US dollar value of any cash dividends we pay, which could have a corresponding effect on the market price of the ADSs.

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

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

Our future tax obligations may adversely affect our profitability

According to the newly implemented Alternative Minimum Tax, or AMT, Act effective from January 1, 2006, a company is subject to a 10% AMT if its annual income exceeds NT$2 million, and an individual will be subject to a 20% AMT if his/her annual income exceeds NT$6 million. The imposition of the AMT is designed to remedy the current excessive tax incentives for individuals and businesses. For businesses, the incomes which previously enjoyed tax-exemption privileges under relevant tax regulations, such as the Statute for Upgrading Industries will be subject to the new AMT system for the calculation of business taxpayers’ aggregate incomes. The AMT Act also provides that businesses already qualified for five-year tax exemption before December 31, 2005 may continue to enjoy tax incentives and not to be subject to the AMT, so long as the construction of their investment projects breaks ground within one year and is completed within three years of the implementation of the AMT Act. We have evaluated our 2007 regular income tax, which is lower than the AMT and concluded that the imposition of the AMT increased our current tax payable by NT$35.0 million (US$1.1 million) without any increase in our income tax expense for the year ended December 31, 2007.

Risks Relating to the PRC

Our operations in the PRC may expose us to political, regulatory, economic and foreign investment risks in the PRC

Some of our customers and foreign competitors have expanded their operations to the PRC. In order to remain competitive and to position ourselves to gain market share, we established a subsidiary named Siliconware Technology (Suzhou) Limited, or Siliconware Suzhou, in 2002, which currently is engaged in the assembling and testing of semiconductors of wire bonding based types DRAM modules, flash memory cards, transistors and other electronic components.

Prior to 1978, the PRC operated under a central economic planning system. All production and economic activities in the country were governed by the economic goals set out in the five-year plans and annual plans adopted by central authorities. Since 1978, the PRC government has permitted foreign investment and implemented economic reforms, gradually changing from a planned economy to a market-oriented economy. However, many of the reforms and economic policies adopted or to be adopted by the PRC government are unprecedented or experimental in nature and may have unforeseen results, which may have an adverse effect on enterprises with substantial business in the PRC, including us.

Since 1979, many laws and regulations dealing with general economic matters or particular economic activities have been promulgated in the PRC. However, enforcement of existing laws and regulations may be uncertain and sporadic and implementation and interpretation thereof may be inconsistent. The PRC judiciary is relatively inexperienced and underdeveloped in enforcing the laws and regulations that currently exist, leading to a degree of uncertainty as to the outcome of any litigation. Further, it may be difficult to obtain swift and equitable enforcement or to obtain enforcement of a judgment by a court of another jurisdiction. The PRC’s legal system is

based on written statutes and, therefore, decided legal cases do not have binding legal effect, although they are often followed by judges as guidance. The introduction of new PRC laws and regulations and the interpretation of existing laws and regulations may be subject to policy changes reflecting domestic political or social changes. As the PRC legal system develops, there can be no assurance that changes in such legislation or interpretation thereof would not have a material adverse effect on our business, financial condition, results of our operations and future prospects.

The discontinuation of any preferential tax treatment currently available to us and the increase in the enterprise income tax in the PRC could adversely affect our results of operations

Prior to January 1, 2008, the basic income tax rate for foreign-invested enterprises in the PRC was 33% (30% enterprise income tax and 3% local income tax). However, the PRC government provided various incentives, including reduced tax rates and other measures, to foreign-invested enterprises and companies that meet certain criteria. Our subsidiary Siliconware Suzhou was qualified for the favorable tax treatment and was entitled to a preferential enterprise income tax rate of 15%. In addition, Siliconware Suzhou is a foreign-invested manufacturing enterprise with an approved term of more than ten years. Thus, Siliconware Suzhou is entitled to a two-year exemption from the enterprise income tax from the first profitable year of operation, and a 50% relief from the enterprise income tax for the subsequent three years. The first profitable year of operation for Siliconware Suzhou was in 2007.

Under the PRC Enterprise Income Tax Law, or the EIT Law, which took effect on January 1, 2008, the PRC adopted a uniform income tax rate of 25% for all enterprises in China (including foreign-invested enterprises) and revoked many of the current tax exemption, reduction and preferential treatments applicable to foreign-invested enterprises. However, a transition period for enterprises, whether foreign-invested or domestic, that were subject to an enterprise income tax rate lower than 25% prior to the effective date allows these enterprises to continue enjoying the lower rate and gradually transit to the new tax rate within five years after the effective date of the EIT Law. Enterprises that are currently entitled to exemptions or reductions from the standard income tax rate for a fixed term may continue to enjoy such treatment until the fixed term expires. However, for foreign-invested enterprises which are currently entitled to the two-year exemption and the subsequent three-year 50% relief from enterprise income tax but have yet not experienced the first profitable year, the two-year exemption begins from January 1, 2008, regardless of whether such enterprise is profitable at that time. Preferential tax treatments will continue to be granted to enterprises classified as “new and high technology enterprises strongly supported by the state”, which will be entitled to a 15% enterprise income tax rate. Any reduction or elimination of these preferential tax benefits may have an adverse effect on our results of operations.

We are in the process of evaluating the impact of the EIT Law. We cannot assure you that the current preferential tax treatments and the current level of the enterprise income tax enjoyed by our PRC operating subsidiary will continue, and any legislative changes to the tax regime could discontinue any preferential tax treatment applicable to our subsidiary in the PRC.

Changes in PRC foreign exchange regulations may adversely affect our results of operations and financial condition

The exchange rate between the Renminbi and the U.S. dollar and other foreign currencies is affected by, among other things, changes in China’s political and economic conditions. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new policy, the Reminbi is permitted to fluctuate within a narrow and managed band against a basket of foreign currencies. This change in policy has resulted in an approximately 15.6% appreciation of Reminbi against the U.S. dollar between July 21, 2005 and April 30, 2008. There remains significant international pressure on the PRC government to adopt a more flexible currency policy, which could result in a further and more significant appreciation of Renminbi against the U.S. dollar. Any increase in the value of the Renminbi might adversely affect the growth of the Chinese economy, increase our operating expenses as well as the competitiveness of various industries in China, including our industry, which could in turn affect our financial condition and results of operations.

Risks Related to Ownership of Our Shares or ADSs

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

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

	•		distribution of share dividends or free distribution of our shares;

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

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

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

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

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

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

Furthermore, if holders of at least 51% of the ADSs outstanding at the relevant record date instruct the depositary to vote in the same manner regarding a resolution, including election of directors and/or supervisors, the depositary will appoint our Chairman, or his designee, to represent the ADS holders at the shareholders’ meetings and to vote the shares represented by the ADSs outstanding in the manner so instructed. If by the relevant record date the depositary has not received instructions from holders of ADSs holding at least 51% of the ADSs to vote in the same

manner for any resolution, then the holders will be deemed to have instructed the depositary to authorize and appoint our Chairman, or his designee, to vote all the shares represented by ADSs at his sole discretion, which may not be in your interest.

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

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

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

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

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

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

You may not be able to enforce a judgment of a foreign court in the ROC

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

	•		the court rendering the judgment does not have jurisdiction over the subject matter according to ROC law;

	•		the judgment or the court procedures resulting in the judgment is contrary to the public order or good morals of the ROC;

	•		the judgment was rendered by default, except where the summons or order necessary for the commencement of the action was duly served on us within the jurisdiction of the court rendering the

judgment within a reasonable period of time and in accordance with the laws and regulations of such jurisdiction, or with judicial assistance of the ROC; or

•

judgments of ROC courts are not recognized and enforceable in the jurisdiction of the court rendering the judgment on a reciprocal basis.

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

Based upon the past and projected composition of our income and valuation of our assets, including goodwill, we believe we were not a passive foreign investment company, or PFIC, for 2007, and do not expect to become one in the future, although there can be no assurance in this regard. If, however, we were or were to become a PFIC, such characterization could result in adverse U.S. tax consequences to you if you are a U.S. investor. For example, if we are a PFIC, our U.S. investors will become subject to increased tax liabilities under U.S. tax laws and regulations and will become subject to burdensome reporting requirements. The determination of whether or not we are a PFIC is made on an annual basis and will depend on the composition of our income and assets from time to time. Specifically, we will be classified as a PFIC for U.S. tax purposes if either: (i) 75% or more of our gross income in a taxable year is passive income, or (ii) the average percentage of our assets by value in a taxable year which produce or are held for the production of passive income (which includes cash) is at least 50%. The calculation of the value of our assets will be based, in part, on the quarterly market value of our shares, which is subject to change. We cannot assure you that we will not be a PFIC for 2008 or any future taxable year. See “Taxation — U.S. Federal Income Tax Considerations for U.S. Persons — Passive Foreign Investment Company.”

Our objective is to be the leading worldwide, full service independent provider of semiconductor packaging and testing services. Key elements of our strategy include:

	•		providing a full range of packaging and testing services, including turnkey capabilities to simplify our customers’ supply chain management;

	•		offering leading packaging and testing technology to attract and retain customers;

	•		focusing on customer service and working with our customers on developing and fulfilling their current and future semiconductor packaging and testing needs;

	•		leveraging our existing foundry relationships and Taiwan location to enable our customers to easily integrate all of their outsourced semiconductor manufacturing needs; and

	•		diversifying and expanding our customer base geographically, by customer type and by end-market application, to capitalize on growing markets including communications and increased outsourcing from vertically integrated semiconductor device manufacturers and systems original equipment manufacturers.

Because our services are, and will continue to be, dependent on the requirements of semiconductor companies for independent testing and assembly services, any downturn in the highly cyclical semiconductor industry may reduce demand for our services and adversely affect our results of operations. Our operations, however, are not subject to any clear seasonal effects.

Our Packaging Services

We offer a broad range of package formats designed to provide our customers with a full array of packaging solutions. The packaging solutions we currently offer to our customers include substrate packages, which include ball grid array and system in packages (incorporating multiple semiconductor chips) and flip-chip ball gird array packages, together with lead-frame packages. Our flip-chip ball grid array packages are based on the Flex-On-Cap wafer bumping and redistribution technologies. Semiconductor packaging serves to protect semiconductor chips, to facilitate their integration into electronic systems and to enable the dissipation of heat produced by the final product. The packaging process begins with dicing patterned silicon wafers into separated dies. Each die is attached to a substrate or lead-frame by die-attached material. Substrate or leads on the lead-frame are then connected by extremely fine gold wires to the input/output terminals on the chip, using machines called wire bonders. Each chip is then encapsulated, generally in a plastic casing molded from a molding compound, with only the leads protruding from the finished casing. To complete the packaging process, excess molding compound is eliminated from the packaged semiconductor chip and the leads are trimmed and formed into various shapes.

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

	•		the size of the package;

	•		the number of electrical connections the package can support; and

	•		the thermal and electrical requirements of the package.

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

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

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

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

Substrate Packages

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

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

	•		smaller size;

	•		greater pin count;

	•		greater reliability;

	•		better electrical signal integrity; and

	•		easier attachment to a printed circuit board.

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

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

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

Lead-Frame Packages

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

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

Testing and Other Services

Semiconductor testing measures and ensures the performance, functionality and reliability of a packaged semiconductor device. Testing semiconductor devices requires significant technical expertise and knowledge of the

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

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

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

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

Other Testing Services. In addition to wafer probing and final testing services described above, we also provide “system-level testing” service for testing products on motherboards, “TDBI-test during burn-in” service to screen out device infant mortality, “laser repair/laser trim” service to modify device connection structure for specific product applications, “lead/ball scanner” service to screen out abnormal products, including bent lead or ball defective devices, so as to prevent them from being shipped to the end customers, “marking” service to specify the unique customer logo and batch identification on products and “tape and reel” service to packaging devices into one complete reel for surface mount operation.

Customers

We currently have more than 100 customers worldwide, and our customers include many of the largest semiconductor companies in the world. In 2005, 2006 and 2007, 42.3%, 40.4% and 41.5% of our net operating revenues were derived from sales to our top five customers, respectively, and 62.6%, 62.8% and 61.0% of our net operating revenues were derived from sales to our top ten customers, respectively. In 2007, our top two customers provided approximately 10.6% and 10.2%, respectively, of our net operating revenues. Our representative customers as of December 31, 2007 include Advanced Micro Devices Inc., Broadcom Corporation, Intel Corporation, MediaTek, Marvell Semiconductor Inc., NVIDIA Corp., Powerchip Semiconductor Corp., SanDisk Corporation, Trident Technologies Inc. and Xilinx, Inc.

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

Set forth below is a geographic breakdown of our net operating revenues for the periods presented below, categorized by geographic region based on the jurisdiction in which each customer is headquartered:

(1)		Includes primarily Japan, Germany and Korea.

Sales from outside of Taiwan accounted for 62.0%, 64.1% and 64.6% of our net operating revenues in 2005, 2006 and 2007, respectively. We primarily target U.S. and Canadian semiconductor companies that contract their wafer foundry services to major independent ROC foundries. Our U.S. and Canadian customers, including AMD and NVIDIA Corp., are world-leading suppliers of graphic chipsets. Our U.S. customers mainly require quad flat packages and substrate packages. We also focus on marketing our packaging and testing services in Japan and Europe and expect sales to these two areas to increase in the near future.

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

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

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

Sales and Marketing

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

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

Our sales and marketing efforts are carried out by our sales team in Taichung and Hsinchu near many of Taiwan’s leading domestic semiconductor companies. In addition, our subsidiary Siliconware U.S.A., with offices in San Jose and Huntington Beach, California, Chelmsford, Massachusetts, Tempe, Arizona and Lewisville, Texas, which facilitate communications and maintain relationships with companies headquartered in North America. Transactions are conducted pursuant to purchase orders transmitted to our headquarters in Taiwan. We also have established our Japan office in Tokyo and Europe office in Germany to give our customers support in closer proximity.

Quality Control

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

Our comprehensive quality control and environmental protection programs have received numerous accredited International Standards Organization certifications, including ISO 9002 in 1992, ISO 9001 in 1993, QS 9000 in 1999 and ISO 14001 in May 1999. We undergo periodic audits to maintain our ISO certifications. Although some semiconductor companies view the ISO certification as a basis for initiating contact with a potential subcontractor, they generally perform separate production and quality audits of the subcontractors themselves. We also received TS16949 certification for our quality control in August 2003 and OHSAS 18001 certification for safety and health management system in December 2004.

As a result of our ongoing focus on quality, we achieved average quarterly packaging yields of 99.8% for lead frame base, substrate base, flip-chip and wafer bumping in 2007. Packaging yield, which is the industry standard for measuring production yield, is equal to the number of IC packages that are shipped for packaging divided by the number of individual ICs that are attached to substrates or lead-frames.

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

Research and Development

We focus our research and development efforts on developing new package designs and improving the efficiency and capabilities of our production process technologies. Production process enhancements include:

	•		reduction of the size and thickness of semiconductor device packages;

	•		increasing input/output density of semiconductor device packages;

	•		enhancement of the electrical, thermal and reliability performance of semiconductor device packages;

	•		reduction of spacing between leads;

	•		reduction of the height of gold wire used in the wire bonding process;

	•		increasing packaging yields;

	•		shortening cycle times; and

	•		investigating the use of new or replacement raw materials.

We believe that technology development is one of the key success factors in the semiconductor packaging and testing industry. We work with our customers, equipment manufacturers or materials suppliers to develop advanced processing capabilities. We are also developing a Fan-Out Wafer-Level-CSP technology for advanced RF modules. Moreover, we work with customers early in the process of wafer design to ensure that their packaging needs are met and that our packaging services provide our customers with the flexibility they require. Our research and development personnel are divided among our design department, characterization department and manufacturing technology development department. In addition, our quality assurance and manufacturing personnel also participate in research and development activities. In 2005, 2006 and 2007, our research and development expenses amounted to NT$858 million, NT$1,194 million and NT$1,288 million (US$39.7 million), respectively.

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

Supplies

Raw Materials

Our packaging operations require adequate supplies of materials and equipment on a timely basis. The principal raw materials used in packaging are substrates, lead-frames, gold wire and molding compound. We purchase materials based on customer forecasts and our customers are generally responsible for any unused materials in excess of the quantity that they indicated they would need.

Our major suppliers of raw materials, including Chang Wah Electromaterials Inc., Chroma New Material Corp., Kinsus Interconnect Technology Corp., Phoenix Precision Technology Corp., Sumitomo Metal Mining Asia Pacific Pte Ltd., and Sumitomo Bakelite (Taiwan) Co., Ltd. are leading companies in the types of materials they supply. We work closely with them and provide them with rolling forecasts. For 2005, 2006 and 2007, our raw material costs were 56.0%, 56.2% and 57.1%, respectively, of cost of goods sold.

We do not maintain large inventories of raw materials; we usually only maintain enough for one month’s production based upon regular estimates of orders from customers. Our principal suppliers usually dedicate portions of their inventories as reserves to meet our production requirements. Nevertheless, on occasion when customer orders have exceeded the supply of raw materials, we have typically been able to obtain extensions from our customers to allow sufficient supply to become available. Such arrangements help us remain cost competitive in today’s market. In the past, prices of our principal raw materials have not been volatile.

Equipment

In addition to raw materials, the availability of packaging and testing equipment is critical to our services. We generally seek to maintain equipment from different suppliers with broad functionality and flexibility for different packaging types to enhance capacity utilization. We purchase packaging equipment from major international manufacturers, including Apic Yamada Corporation, Kulicke & Soffa Industries Inc., ASM Technology Singapore

PTE LTD. and TOWA Corporation. As of December 31, 2007, we operated 4,653 wire bonders and 338 testers in Taiwan. In addition, we have 427 wire bonders and 22 testers in our Suzhou facility in the PRC. We must order equipment in advance of customer demand to expand our capacity, based on our expectation of future demand for our packaging and testing services.

Testing equipment is one of the critical components of the wafer probing and device testing process. We generally seek to maintain testers from different suppliers with similar functionality and the ability to test a variety of different semiconductors. In general, certain semiconductors can only be tested on a limited number of specially configured testers. Our major suppliers of testing equipment include Verigy Ltd, which took over the semiconductor testing business of Agilent Technologies, Inc. in June 2006, Advantest Taiwan Inc., and Teradyne Inc.

Competition

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

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

	•		the breadth of package and test offerings;

	•		technical competence;

	•		manufacturing yields;

	•		manufacturing cycle times;

	•		customer service; and

	•		price.

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

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

	•		we generally have lower unit costs because of our higher utilization rates; and

	•		we offer a wider range of services in terms of complexity and technology.

Strategic Investments

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

	•		Phoenix Precision Technology Corporation. As of December 31, 2007, we held, directly and indirectly, a 16.9% equity interest in Phoenix Precision, a supplier of semiconductor raw materials, including substrates. Mr. Bough Lin, our Chairman, Mr. Yen-Chun Chang, one of our directors, and Ms. Teresa Wang, one of our supervisors, are directors of Phoenix Precision. Ms. Teresa Wang is also the Chief Financial Officer of Phoenix Precision. Jerome Tsai, one of our directors, is supervisor of Phoenix Precision. Mr. Wen-Lung Cheng, one of our supervisors, is supervisor of Phoenix Precision.

	•		ChipMOS Technologies (Bermuda) Ltd., or ChipMOS Bermuda. As of December 31, 2007, we held a 14.5% equity interest in ChipMOS Bermuda, a semiconductor packaging and testing and LCD driver and IC manufacturing company. Mr. Jerome Tsai, one of our directors, is a director of ChipMOS Bermuda.

Intellectual Property

As of December 31, 2007, we held 468 Taiwan patents, 288 U.S. patents and 69 PRC patents related to various semiconductor packaging technologies, including patents for improvements of thermal and electrical performance used in the semiconductor packaging process. As of December 31, 2007, we also had a total of 73 pending patent applications in the United States, 131 in Taiwan and 141 in the PRC. In addition, we had registered “SPIL” as a trademark and as a servicemark in Taiwan.

We have licensed from Freescale, formerly part of Motorola prior to April 2004, the technology for ball grid array for which we make royalty payments based upon the number of pads or balls used in our packages. This license will expire in December 2010. We have also entered into other technology alliances by licensing leading-edge package technologies, including:

	•		Wafer Bumping and Redistribution technology, which enables us to form and/or redistribute bumps on the chip to make a silicon die, is able to be directly attached to the substrate using the aforementioned bumps rather than wire bonding. This license will expire in November 2014.

	•		Wafer Level CSP technology, which enables us to produce a chip scale package at the stage of wafer level. This license will expire in January 2011.

	•		Packaging technology pertaining to flip-chips, which offer us a cost-effective solution for high performance ASIC and system-on-chip, or SoC, designs. We acquired this license in August 2001. This license will expire in January 2010.

	•		TCC technology which enables us to produce micro ball grid array. This license will terminate at the expiration of the patent.

	•		Electrical enhanced-PBGA technology which enables us to produce high electrical performance packages by consolidated power ring and ground ring. This license will terminate at the expiration of the patent.

Our ongoing royalty expenses to license intellectual property were immaterial compared to our revenues in any of 2005, 2006 and 2007.

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

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

•

discontinue the use of disputed process technologies;

	•		pay substantial damages;

	•		develop non-infringing technologies; or

	•		acquire licenses to the technologies that we had allegedly infringed.

Environmental Matters

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

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

As for the newly developed bumping process, waste water is produced when water is used for rinsing wafers in the processes of etching and solder deposition. Gases come from the emissions of solvents that are used for cleansing wafers during the bumping process.

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

Insurance

Our insurance policies on buildings, equipment and inventories cover physical damages due to natural disasters, subject to certain exceptions in the policy. In Taiwan, our insurance coverage includes business interruption losses. We also maintain insurance policies on inland transit of inventories. Our insurance policies cover the risk of loss of the silicon wafers delivered to us while they are in our possession or consigned by our customers and/or during inland transportation.

Employees

See “Item 6. Directors, Senior Management and Employees — D. Employees” for certain information relating to our employees.

Capital Expenditures and Divestitures

Our capital expenditures amounted to NT$8,245 million, NT$11,039 million and NT$12,151 million (US$374.7 million) in 2005, 2006 and 2007, respectively. Our initial budget for capital expenditures for 2008 is approximately NT$12,000 million (US$370.0 million), which is funded from our retained earnings and primarily used for equipment purchases and building improvements. We may adjust the amount of our capital expenditures upward or downward based on the progress of our capital projects, market conditions and our anticipation of future business outlook. See “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources.”

We have made, and expect to continue to make, capital expenditures in connection with the expansion of our production capacity. The table below sets forth our principal capital expenditures, paid or committed, for the periods indicated.

Litigation

On March 1, 2006, we were informed of a lawsuit brought by Tessera in the United States District Court for the Northern District of California against us, our subsidiary Siliconware USA, Inc., and five other semiconductor companies and their subsidiaries. Tessera alleged that some of our packaging services have infringed patents owned by Tessera and that we breached a license agreement with Tessera. In May 2007, the parties stipulated to a stay pending a final determination of an investigation directed against other parties (including certain co-defendants in the lawsuit) conducted by the ITC. Pursuant to the stipulation, the court stayed the litigation.

Beginning in February 2007, we filed in the U.S. PTO requests for reexamination of five Tessera’s patents, four of which Tessera had asserted against us. The PTO has issued either office actions or action closing prosecution favorable for us in all of the reexaminations.

On September 12, 2007, we, along with Siliconware USA, Inc. and three other co-defendants (and their subsidiaries) in the lawsuit, moved for a temporary restraining order, or the TRO, and a preliminary injunction prohibiting Tessera from initiating any action before the ITC against us for infringement of patents subject to the license agreements. On November 1, 2007, the court barred Tessera from initiating an action against us, Siliconware USA, or our three co-defendants before the ITC or outside of California alleging infringement of patents subject to licenses with Tessera until Tessera demonstrates that the packages accused of infringement are not under licenses. On January 11, 2008, Tessera served a draft ITC complaint on us alleging infringement of Tessera’s ‘977, ‘326, and ‘419 patents. On February 19, 2008, the court ruled that Tessera had demonstrated that laminate substrate packages are not under the license between us and Tessera. Tessera has not formally served its ITC complaint on us.

Because litigation is inherently unpredictable, we are unable to predict the results or outcome of any dispute. Currently, we are unable to assess the potential liabilities arising out of Tessera’s claims due to the fact that information provided with regard to the infringement scope is insufficient.

Item 5. Operating and Financial Review and Prospects

Unless stated otherwise, the discussion and analysis of our financial condition and results of operations in this section apply to our financial information as prepared according to ROC GAAP. You should read the following discussion of our financial condition and results of operations together with the financial statements and the notes to these statements included in this annual report. Our financial statements are prepared according to ROC GAAP, which differ from US GAAP. For a discussion of the material differences, see note 33 to our financial statements included elsewhere in this annual report.

Operating Results

Overview

We are one of the world’s leading independent providers of semiconductor packaging and testing services. We offer a complete portfolio of packaging and testing solutions, including advanced substrate packages such as flip-chip ball grid packages, together with lead-frame packages, and testing services for logic, mixed signal and embedded memory devices. We also offer our customers complete turnkey solutions, including packaging, testing and direct shipment of semiconductor devices to the destinations designated by our customers.

We recorded operating income of NT$7,249 million, NT$12,243 million and NT$16,194 million (US$499.4 million) in 2005, 2006 and 2007, respectively. Increases in our operating income were also attributable to increases in our offering more advanced packaging services and testing of high-performance semiconductor products.

Intense competition in the semiconductor industry worldwide resulted in decreases in the average selling prices of our manufacturing services. We expect that average selling prices for most of our semiconductor packages to continue to decline in the future. A decline in average selling prices of our semiconductor packages, coupled with high

depreciation cost resulting from our purchase of additional equipment during the previous periods, if not offset by reductions in the other cost of producing those packages, would decrease our gross margins.

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

	•		negotiate better pricing terms with our suppliers, including quantity discounts;

	•		find alternative, less expensive sources of raw materials;

	•		maximize production efficiency of our employees; and

	•		engage in utility conservation programs.

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

Consolidation

Under ROC GAAP prior to January 1, 2005, we were required to include in our consolidated financial statements direct and indirect subsidiaries with total assets or total operating revenues that individually comprised at least 10% of our total assets or total operating revenues. For subsidiaries that did not individually exceed such threshold, we calculated whether the aggregate of either the total assets or total operating revenues of such subsidiaries exceeded 30% of our respective non-consolidated amounts. Each of such subsidiaries was required to be consolidated only if its total assets or total operating revenues constituted at least 3% of our non-consolidated total assets or total operating revenues, respectively. However, the adoption of the amended ROC GAAP Statement of Financial Accounting Standards, or ROC SFAS No. 7, “Consolidation Financial Statements” effective January 1, 2005 has expanded the scope of consolidation to include all investees that are not majority-owned, but over which we can exercise significant control. For each of 2005, 2006 and 2007, we consolidated five subsidiaries: Siliconware Investment Company Ltd., SPIL (B.V.I.) Holding Limited, Siliconware U.S.A. Inc., SPIL (Cayman) Holding Limited and Siliconware Technology (Suzhou) Limited, each in which we own a 100% equity interest.

Upon adoption of the Order of the Financial Supervisory Commission, Executive Yuan No. 0930154140 in January 2005, we were required to prepare consolidated financial statements pursuant to ROC SFAS No. 7 on a semiannual basis. However, the Commission released the Order No. 0960064020 in November 2007, which requires us to prepare consolidated financial statements on a quarterly basis commencing January 2008.

Delay in Recognition of Investment Income in Certain Investee Companies Accounted for Under Equity Method

ChipMOS

As of March 27, 2007, we owned a 28.8% equity interest in ChipMOS, a semiconductor packaging and testing and LCD driver and IC manufacturing company located in Hsinchu, Taiwan. Prior to January 1, 2005, the ROC Securities and Futures Bureau allowed us to delay our recognition of investment income or loss in certain investee companies accounted for under the equity method until the following accounting year. As a result, in 2004, we delayed the recognition of investment income of NT$668 million in relation to the financial results of ChipMOS, until 2005 and recorded the above-mentioned amount of NT$668 million as cumulative effects of changes in accounting principles for 2005. From January 1, 2005, we adopted ROC Statement of Financial Accounting Standards No. 5, “Accounting for Long-term Equity Investment”, pursuant to which we ceased to defer the recognition of investment income or loss of investees accounted for under the equity method until the subsequent year, and recognized investment income or loss from all investees accounted for under the equity method based on investees’ audited financial statements for the same periods. We recognized investment income of NT$433 million and NT$1,125 million for the years ended December 31, 2005 and 2006, respectively, and NT$246 million (US$7.6 million) for the period between January 1, 2007 and March 27, 2007 from ChipMOS’s financial results. In 2005, 2006 and 2007, our investment income under US GAAP from ChipMOS were NT$469 million, NT$1,045 million and NT$253 million (US$7.8 million), respectively. As a result, our financial results under US GAAP would not provide meaningful

year-to-year comparison to our financial results under ROC GAAP. Under US GAAP, there is no provision that allows us to delay recognition of financial results of ChipMOS or any other investee accounted for under the equity method prior to January 1, 2005.

Pursuant to a Share Purchase and Subscription Agreement entered into among us, ChipMOS Technologies (Bermuda) Ltd., or ChipMOS Bermuda and ChipMOS, on March 27, 2007, we sold, and ChipMOS Bermuda and ChipMOS purchased, all of the common shares of ChipMOS, at par value NT$10 per share, owned by us for a total cash consideration of US$191,147,464. In addition, we subscribed for 12,174,998 newly issued common shares of ChipMOS Bermuda, at par value US$0.01 per share, for an aggregate consideration of US$76,458,987, representing a purchase price of US$6.28 per common share of ChipMOS Bermuda. Upon the completion of the sale and purchase, we owned 14.7% of ChipMOS Bermuda. As of December 31, 2007, we held a 14.5% ownership in ChipMOS Bermuda.

Double Win

Prior to January 1, 2005, recognition of our investment income (loss) in Double Win was recorded in the subsequent year on a delayed basis. The deferred recognition of the investment loss of NT$17 million from Double Win’s 2004 financial results was added to the cumulative effects of changes in accounting principles in 2005. No recognition of investment income (loss) in Double Win was recorded in 2006 and 2007.

Change in Mix of Services

Beginning in 2004, our substrate packages accounted for a majority of our net operating revenues in relation to our packaging business. Our lead-frame packages, which had been our major packaging technology since January 1998, still account for a substantial percentage of our net operating revenues.

The following table shows, for the periods indicated, the amount of our packaging by package types and testing revenues (which are more fully described in “Item 4. Information on the Company—B. Business Overview—Our Business”).

Expansion and Utilization Rate

As we continue to expand our capacity in order to meet increasing demand from our customers, the number of our wire bonders and testers increased to 3,961 and 273, respectively, as of December 31, 2005, 4,249 and 317, respectively, as of December 31, 2006 and 5,080 and 360, respectively, as of December 31, 2007.

Our operating results are affected by relatively high fixed costs. As a result, capacity utilization rates can significantly affect margins as the unit cost of packaging and testing services generally decreases as fixed charges, including depreciation expenses on our equipment, are allocated over a larger number of units. Our utilization rates have varied from period to period as we have expanded our production capacity. We have been successful in minimizing the industry-wide fluctuation in capacity utilization rates by deploying flexible packaging equipment for use in the production of different packages and by utilizing our test equipment also for probing purposes. Our ability to

maintain or enhance our margins will continue to depend in part on our ability to effectively manage capacity utilization rates. The capacity utilization of our facilities was 94%, 87% and 90% in 2005, 2006 and 2007, respectively.

Applications of Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements included elsewhere in this annual report, which have been prepared in accordance with ROC GAAP. ROC GAAP vary in certain significant respects from US GAAP. These differences and their effects on our financial statements are described in note 33 to our audited consolidated financial statements included in this annual report. The preparation of our audited consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, accounts receivable and allowance for doubtful accounts, inventory, marketable securities, deferred tax asset valuation allowance, employee bonuses, impairment of long-lived assets and equity investments, and goodwill impairment. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates using different assumptions or conditions.

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

Revenue Recognition

We principally provide packaging and testing services of ICs, which may be packaging only, test only or turnkey solutions. Revenues are recognized when services have been provided based on transaction terms and when collectibility is reasonably assured. If turnkey services are negotiated in one contract, we recognize revenues based on the quoted prices when all of the revenue recognition criteria are met.

Accounts Receivable and Allowances for Doubtful Accounts

We record accounts receivable expected to be collected over one year at present value by using predetermined interest rate whereas recording those expected to be collected within one year at present value due to the fact that the difference between the maturity value and the fair value discounted by implicit interest rate is immaterial and the frequency of transactions is high. The allowance for doubtful accounts is estimated based on the evaluation of collectibility and aging analysis.

Inventory Reserves

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

Inventories are recorded at cost when acquired under a perpetual inventory system and are stated at the lower of their aggregate cost, which is determined by the weighted-average method and total inventory approach, or their market value as of the balance sheet date. The market value of raw materials and supplies is determined on the basis of their replacement cost, while the market value of finished goods and work in progress is determined on the basis of their net realizable value. The allowance for loss on obsolescence and decline in market value is recorded based on inventory aging and obsolescence, when necessary.

Impairment of Long-Lived Assets

We review long-live assets for the purpose of determining the amount of impairment quarterly under ROC GAAP. We perform impairment test whenever an event occurs or evidence indicates that the carrying amount of an asset exceeds its recoverable amount. A recoverable amount is measured as the higher of the net selling price or value in use. The net selling price is the amount obtainable from the sale of an asset in an arm’s-length transaction between knowledgeable and willing parties, less any direct incremental disposal costs. The value in use is the present value of estimated future cash flows expected to arise in its remained useful life.

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

In 2005, 2006 and 2007, we recognized an impairment charge of NT$69 million, NT$28 million and NT$49 million (US$1.5 million), respectively, for packaging and testing assets to be disposed of to reduce the carrying value of the assets to their estimated fair value less cost of sale. The fair value of the assets to be disposed of was determined by the estimated net realizable value of the assets. We determined the estimated net realizable value of these assets based on the condition and anticipated future cash flows of these assets. The impairment charge was mainly related to our decision to dispose certain machinery and equipment due to technology phase out and replacement in 2005, 2006 and 2007.

Impairment of Equity Investments

We evaluate quarterly our equity investments for impairment due to declines in the market value that are considered other than temporary under ROC GAAP. Such evaluations include an assessment of general economic and company-specific considerations, such as customer forecasts and regularly updated projections of operating results. In the event of a determination that a decline in market value is other than temporary, loss is recognized in the current year’s income. The evaluation of whether a decline in market value is other than temporary requires considerable management judgment. For an investee who resolves to liquidate or dissolve, a one-time write-off would be recorded to the extent that the estimated proceeds would be obtained and the amount of investment balance would not be recovered.

Provision for Income Taxes and Deferred Tax Asset Valuation Allowances

As of December 31, 2007, we had approximately NT$1,796 million (US$55.4 million) of net deferred tax assets related principally to investment tax credits that expire at various dates through 2011, the unrealized loss on idle assets and loss carryforwards. Valuation allowance was provided to reduce the deferred tax assets to the amount that we believe is more likely than not to be realized. We have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowances. In the event we determined that we would be able to realize our deferred tax assets in the future in excess of our net recorded amount, an adjustment to our deferred tax assets would increase income in the period such determination was made. Similarly, should we determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment of our deferred tax assets would be charged to income in the period such determination was made.

Employee Bonuses

Some of our employees are entitled to bonuses in accordance with applicable provisions of our articles of incorporation. Employee bonuses are determined at 10% of distributable retained earnings. Distributable retained earnings are calculated as retained earnings after various reserves are made in accordance with ROC law and our articles of incorporation and after appropriation for remuneration to directors are made. Employee bonuses may be granted in cash, shares or a combination of both. Under ROC GAAP, such bonuses are appropriated from retained earnings during the accounting period during which such shareholders’ approval is obtained. If such employee bonuses are settled through the issuance of our shares, the amount charged against retained earnings would be based on the par value of the common shares issued. Under US GAAP, the employee bonus expense is initially accrued at the end of the period when services are rendered, at 10% of the distributable retained earnings. When bonuses are

approved by the shareholders in the subsequent year, an additional compensation expense is recorded for the difference between the par value and the fair market value of shares granted to employees.

Goodwill

Goodwill arising from business combination is recognized under US GAAP as the difference between the fair market value of shares issued and the fair market value of net assets acquired. Effective January 1, 2002, SFAS No. 142 requires that we cease amortization of goodwill and perform an impairment review, at the “reporting unit” level, upon adoption and at least annually thereafter. Since we operate on an integrated basis, we have only one reporting unit. Based on the comparison of the fair value and carrying value of our company, we concluded that goodwill was not impaired as of the adoption of SFAS No. 142 and as of December 31, 2007.

Embedded Derivatives

Under US GAAP, the convertible or exchangeable option embedded in investments in convertible bonds or exchangeable bonds is separated from the host and accounted for as though it was a discrete derivative instrument when the embedded derivative meets the definition of a derivative instrument under SFAS No. 133 and are not clearly and closely related to the economic characteristics and risks of the host contract. The derivative instrument is measured at fair value, with changes in the fair value reported in earnings.

Under ROC GAAP, when an issuer issues convertible bonds, the entire instrument is recorded as a liability at an amount equal to the proceeds received. Any discount or premium to the par value of the convertible bond is amortized in the statement of operations by using the effective interest rate method. If the convertible bonds contain a redemption premium above their par value amount, the excess is accrued, using the effective interest rate method, over the period to redemption as a charge to interest expense. Upon conversion, the carrying value of the bond is credited to common stock at its par value and the difference between the carrying value of the bond and the par value of the stock is recorded to additional paid-in capital. No gain or loss is recognized.

Under US GAAP, in accordance with SFAS 133, “Accounting for Derivative Instruments and Hedging Activities”, the conversion feature embedded in a bond does not have to be separately accounted for as a derivative at fair value, if the feature is indexed only to the issuer’s own stock and would otherwise be classified in stockholders’ equity in the issuer’s statement of financial position (the “Scope Exception”).

As of December 31, 2005, 2006 and 2007, the total amount of net loss recognized from applying derivative accounting amounting to NT$2,423 million, NT$2,987 million and NT$1,181 million (US$36.4 million), respectively, based on the independent appraisal report.

Description of Revenue and Cost Items

Net Operating Revenues

We generate our net operating revenues primarily from semiconductor packaging and testing operations. Net operating revenues from our semiconductor packaging activities consist of our service fees and the cost of raw materials we purchase to provide semiconductor packaging services. Our net operating revenues do not include the cost of semiconductors, which are our customers’ property.

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

We charge our testing services based on the specific test and the time, usually measured in seconds, to run a test, taking into account the complexity of the semiconductor device and the customer’s test program.

We also generate net operating revenues from the provision of semiconductor turnkey services, which include packaging, testing and drop-shipment services.

Net operating revenues are recognized when services are rendered and the collection is realized or realizable. Our customers are generally invoiced at the time services are rendered, with varying terms of credit between 30 and 90 days from the time of billing.

Cost of Goods Sold

Our cost of goods sold consists principally of:

	•		cost of raw materials purchased for semiconductor packaging services;

	•		direct labor costs; and

	•		overhead including depreciation and maintenance of production equipment, indirect labor costs, indirect material costs, utilities and royalties.

For 2005, 2006 and 2007, our raw material costs were 56.0%, 56.2% and 57.1%, respectively, of our cost of goods sold. Due to our capacity expansion, depreciation expense has increased significantly. For 2005, 2006 and 2007, depreciation, included in overhead, amounted to NT$5,680 million, NT$6,348 million and NT$7,371 million (US$227.3 million), respectively, and was approximately 16.7%, 15.1% and 15.8%, respectively, of our cost of goods sold. The increases in depreciation expenses in 2005, 2006 and 2007 were the result of putting into operation additional 962, 310 and 1,050 wire bonders during 2005, 2006 and 2007, respectively. Increasing depreciation expense increases our cost of goods sold and decreases our gross profit and gross margin. Although we may not expand our packaging capacity as aggressively as we did before the recent downturn in the semiconductor industry, we expect our depreciation costs to increase in absolute terms in the future.

Operating Expenses

Our operating expenses consist of the following:

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

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

Results of Operations

2007 Compared to 2006

Net operating revenues. Net operating revenues increased by 15.8% from NT$57,126 million in 2006 to NT$66,177 million (US$2,040.6 million) in 2007. Net operating revenues from our packaging business increased by 16.8% from 2006 to 2007, whereas net operating revenues from our testing and other services increased by 10.1% in the same periods. These increases were primarily due to the general growth in the semiconductor industry and the increase in demand for personal computers, mobile phones, wireless networks, LCD TV and flash memory card.

Substrate base package sales increased by 9.2% from NT$29,458 million in 2006 to NT$32,180 million (US$992.0 million) in 2007. The increase in substrate base package sales was attributable to an increase in sales of higher-end assembly and wafer level packaging services. In 2007, substrate base package accounted for 48.6% of our net operating revenues, down from 51.6% in 2006.

Lead-frame base package sales increased by 22.1% from NT$16,055 million in 2006 to NT$19,601 million (US$604.0 million) in 2007. The increase in lead-frame base package sales was attributable to an increase in unit sales of lead-frame base package, which increased by 36.7% from 1,911.6 million units in 2006 to 2,613.4 million units in 2007. In 2007, lead-frame base package accounted for 29.6% of our net operating revenues, up from 28.1% in 2006.

Gross profit and gross margin. Our gross profit increased by 27.5% from NT$15,232 million in 2006 to NT$19,418 million (US$598.8 million) in 2007. Our gross margin (gross profit as a percentage of net operating revenues) increased from 26.7% in 2006 to 29.3% in 2007. Our cost of goods sold increased by 11.6% from NT$41,894 million in 2006 to NT$46,759 million (US$1,441.8 million) in 2007, primarily due to a significant increase in package and testing services. The increases in gross profit and gross margin were primarily due to the effective control of unit fixed cost and higher equipment utilization as a result of a significant increase in net operating income from assembling and testing services.

Operating expenses. Operating expenses increased by 7.9% from NT$2,989 million in 2006 to NT$3,224 million (US$99.4 million) in 2007. Operating expenses as a percentage of net operating revenues was 5.2% and 4.9% in 2006 and 2007, respectively.

	•		Selling expenses. Selling expenses decreased by NT$222 million between these two years due to decreases in related fixed expenditure.

	•		General and Administrative Expenses. General and administrative expenses increased by NT$363 million between these two years mainly due to increases in salary expenses and legal fees.

	•		Research and development expenses. Research and development expenses increased by NT$94 million between these two years mainly due to increases in costs for developing new technologies and depreciation expenses.

Operating income and operating margin. We recorded an operating income of NT$12,243 million and an operating margin of 21.5% (operating income as a percentage of net operating revenues) in 2006 and generated operating income of NT$16,194 million (US$499.4 million) and operating margin of 24.5% in 2007. The increase in operating margin was primarily due to an increase in gross margin.

Net non-operating income. Our net non-operating income increased from NT$2,035 million in 2006 to NT$3,434 million (US$105.9 million) in 2007. The increase in net non-operating income was primarily due to an increase in gain on disposal of investments of NT$2,240 million (US$69.1 million), partially offset by a decrease of investment income recognized under the equity method of NT$907 million (US$28.0 million).

Income tax (expense) benefit. We recognized an income tax expense of NT$949 million in 2006 primarily due to the significant increase of income from continuing operations before tax and the decrease in valuation allowance for deferred tax assets. We recognized an income tax expense of NT$2,139 million (US$67.0 million) in 2007 primarily due to a large increase in income before tax. A valuation allowance has been provided against the deferred tax assets to the extent that the tax benefit will more likely than not be realized.

Net income. As a result of the factors discussed above, our net income increased from NT$13,329 million in 2006 to NT$17,489 million (US$539.3 million) in 2007.

2006 Compared to 2005

Net operating revenues. Net operating revenues increased by 31.4% from NT$43,488 million in 2005 to NT$57,126 million in 2006. Net operating revenues from our packaging business increased by 29.9% from 2005 to 2006, whereas net operating revenues from our testing and other services increased by 41.2% in the same periods. These increases were primarily due to the general growth in the semiconductor industry and the increase in demand for personal computers, mobile phones and wireless networks.

Substrate base package sales increased by 34.0% from NT$21,983 million in 2005 to NT$29,458 million in 2006. The increase in substrate base package sales was attributable to an increase in sales of higher-end assembly and wafer level packaging services. In 2006, substrate base package accounted for 51.6% of our net operating revenues, up from 50.6% in 2005.

Lead-frame base package sales increased by 16.0% from NT$13,838 million in 2005 to NT$16,055 million in 2006. The increase in lead-frame base package sales was attributable to an increase in unit sales of lead-frame base package, which increased by 36.7% from 1,911.6 million units in 2005 to 2,613.4 million units in 2006. In 2006, lead-frame base package accounted for 28.1% of our net operating revenues, down from 31.8% in 2005.

Gross profit and gross margin. Our gross profit increased by 59.9% from NT$9,528 million in 2005 to NT$15,232 million in 2006. Our gross margin (gross profit as a percentage of net operating revenues) increased from 21.9% in 2005 to 26.7% in 2006. Our cost of goods sold increased by 23.4% from NT$33,960 million in 2005 to NT$41,894 million in 2006, primarily due to a significant increase in package and testing services. The increases in gross profit and gross margin were primarily due to higher equipment utilization as a result of a significant increase in net operating income from assembling and testing services.

Operating expenses. Operating expenses increased by 31.2% from NT$2,279 million in 2005 to NT$2,989 million in 2006. Operating expenses as a percentage of net operating revenues was 5.2% and 5.2% in 2005 and 2006, respectively.

•

Selling expenses. Selling expenses increased by NT$151 million between these two years mainly due to an increase in salary expenses.

	•		General and administrative expenses. General and administrative expenses increased by NT$222 million between these two years due primarily to increased salaries paid to administrative personnel.

	•		Research and development expenses. Research and development expenses increased by NT$336 million between these two years due to increases in salaries paid to our research and development personnel and costs for developing new technologies.

Operating income and operating margin. We recorded an operating income of NT$7,249 million and an operating margin of 16.7% (operating income as a percentage of net operating revenues) in 2005 and generated operating income of NT$12,243 million and operating margin of 21.5% in 2006. The increase in operating margin was primarily due to an increase in gross margin.

Net non-operating income. Our net non-operating income increased from NT$360 million in 2005 to NT$2,035 million in 2006. The increase in net non-operating income was primarily due to an increase in equity investment income, an increase in other non-operating income and a decrease in other non-operating expenses. The increase in investment income was due to our investment in ChipMOS. In 2006, we recognized an investment income of NT$1,125 million from ChipMOS’s financial results in 2006, whereas in 2005, we recognized an investment income of NT$433 million from ChipMOS’s financial results in 2005. The increase in other non-operating income was due to the cash dividends received from our financial assets carried at cost in Phoenix and King Yuan. The decrease in other non-operating expense was also due to a decrease in the provision for the estimated liabilities arising in connection with our VAT-related tax assessment from NT$323 million in 2005 to nil in 2006 and a decrease in the recognition of impairment loss on idle property, plants and equipment from NT$69 million in 2005 to NT$28 million in 2006.

Cumulative effects of changes in accounting principles. From January 1, 2005, we ceased to defer the recognition of investment income of investees accounted for under the equity method. We recognized an investment income of NT$668 million from ChipMOS’s 2004 financial results and an investment loss of NT$17 million from Double Win’s 2004 financial results as cumulative effects of changes of accounting principles of total NT$651 million in 2005. No cumulative effects of changes in accounting principles were recorded in 2006.

Income tax (expense) benefit. We recognized an income tax expense of NT$16 million primarily due to a large increase of income from continuing operations before tax and a decrease of the investment tax credits available for us in 2005. We recognized an income tax expense of NT$949 million primarily due to the significant increase in income before tax and the decrease in valuation allowance for deferred tax assets. A valuation allowance has been provided against the deferred tax assets to the extent that the tax benefit will more likely than not be realized.

Net income. As a result of the factors discussed above, our net income increased from NT$8,244 million in 2005 to NT$13,329 million in 2006.

Liquidity and Capital Resources

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

Liquidity

As of December 31, 2007, our primary source of liquidity was NT$22,625 million (US$697.7 million) of cash and cash equivalents. As of December 31, 2007, we had total availability under existing short-term lines of credit of NT$7,371 million (US$227.3 million) available from six domestic and foreign financial institutions, of which NT$458 million (US$14.1 million) were used as letters of credit and guarantees. All of our short-term facilities are revolving facilities with a term of one year, which may be extended for terms of one year each with lender’s consent. As of December 31, 2007, we had no short-term borrowing outstanding under these short-term facilities.

The following table sets forth our cash flows with respect to operating activities, investing activities, financing activities and the effect of exchange rate changes on cash for the periods indicated.

Net Cash Provided by Operating Activities

In 2007, net cash provided by operations was NT$24,423 million (US$753.1 million) compared to NT$20,250 million in 2006. The increase in net cash provided by operating activities was primarily the result of a significant increase in net income. Our changes in accounts receivable decreased from NT$336 million in 2006 to a negative NT$2,042 million (US$63.0 million) in 2007, and our changes in accounts payable increased from a negative NT$1,010 million in 2006 to NT$2,304 (US$71.0 million) in 2007. Our depreciation and amortization expenses increased from NT$7,294 million in 2006 to NT$8,169 million (US$251.9 million) in 2007. The increase in our depreciation and amortization expenses in 2007 compared to 2006 was due to additional equipment installed in connection with our capacity expansion program.

In 2006, net cash provided by operations was NT$20,250 million compared to NT$13,215 million in 2005. The increase in net cash provided by operating activities was primarily the result of a significant increase in net income. Our changes in accounts receivable increased from a negative NT$3,767 million in 2005 to a positive NT$336 million in 2006, and our changes in accounts payable decreased from a positive NT$3,020 million in 2005 to a negative NT$1,010 million in 2006, partially offset by a decrease in changes in other payables from NT$62 million in 2005 to a negative NT$369 million in 2006. Our depreciation and amortization expenses increased from NT$6,572 million in 2005 to NT$7,294 million in 2006. The increase in our depreciation and amortization expenses in 2006 compared to 2005 was due to additional equipment installed in connection with our capacity expansion program.

Net Cash Used in Investing Activities

In 2007, cash used in investing activities was NT$5,395 million (US$166.4 million) compared to NT$11,827 million in 2006. The decrease in net cash used in investing activities was primarily the result of a significant increase in proceeds from disposal of long-term investments in the amount of NT$9,564 million (US$294.9 million) in 2007 compared to NT$91 million in 2006. Net cash used in investing activities primarily reflected capital expenditures for property, plants and equipment. These capital expenditures were primarily funded with net cash provided by operating and financing activities. We are at times required to prepay our purchases of land and equipment. As of December 31, 2006 and 2007, we did not have any outstanding balance of any prepayments for purchases of land. Prepayments for purchases of equipment result from contractual agreements involving down payments to suppliers when we place an order for the equipment. As of December 31, 2006 and 2007, outstanding balances of prepayments for purchases of equipment amounted to NT$1,845 million and NT$2,211 million (US$68.2 million), respectively. We have entered into agreements with third parties in connection with our expansion plans. We do not have any written options on non-financial assets.

In 2006, cash used in investing activities was NT$11,827 million compared to NT$6,397 million in 2005. Net cash used in investing activities primarily reflected capital expenditures for property, plants and equipment. These capital expenditures were primarily funded with net cash provided by operating and financing activities. We are at times required to prepay our purchases of land and equipment.

Prepayments for purchases of equipment result from contractual agreements involving down payments to suppliers when we place an order for the equipment. As of December 31, 2005 and 2006, outstanding balances of prepayments for purchases of equipment amounted to NT$2,277 million and NT$1,845 million, respectively. We have entered into agreements with third parties in connection with our expansion plans. We do not have any written options on non-financial assets. In 2006, we reclassified our short-term investments as current financial assets at fair value through profit or loss, which were NT$4,774 million and nil in 2005 and 2006, respectively.

Net Cash Used in Financing Activities

Net cash used in financing activities was NT$6,040 million and NT$11,157 million (US$344.0 million) in 2006 and 2007, respectively. In 2006, net cash used by financing activities reflected primarily our payment of stockholders’ dividends and employees’ bonuses of NT$4,579 million and our repayment of long-term borrowings of NT$5,132 million, offset by the proceeds from long-term borrowings of NT$3,086 million. In 2007, net cash used in financing activities reflected primarily our payment of stockholders’ dividends and employees’ bonuses of NT$10,678 million (US$329.3 million) in aggregate.

Net cash used in financing activities was NT$5,435 million and NT$6,040 million in 2005 and 2006, respectively. In 2005, net cash used by financing activities reflected primarily our long-term borrowings of NT$3,217 million and payment of stockholders’ dividends and employees’ bonuses of NT$1,759 million in aggregate. In 2006, net cash used in financing activities reflected primarily payment of stockholders’ dividends and employees’ bonuses of NT$4,579 million and our repayment of long-term borrowings of NT$5,132 million, offset by the proceeds from long-term borrowing of NT$3,086 million.

Capital Resources

We have made, and expected to continue to make, substantial capital expenditures in connection with the expansion of our equipment purchases and building improvements in Taichunug, Hsinchu and Suzhou. See “Item 4. Information on the Company—B. Business Overview—Capital Expenditures and Divestitures.” Our initial budget for capital expenditures for 2008 is approximately NT$12,000 million (US$370.0 million), which is funded from our retained earnings. We may adjust the amount of our capital expenditures upward or downward based on the progress of our capital projects, market conditions and our anticipation of future business outlook. As a result, we may need to invest in new capacity to improve our economies of scale and reduce our production cost, which would require us to raise additional capital. We cannot assure you that we will be able to raise additional capital should it become necessary on terms acceptable to us or at all. The sale of additional equity or equity-linked securities may result in additional dilution to our shareholders.

As of December 31, 2007, we had outstanding long-term borrowings of NT$3,000 million (US$92.5 million) owed to foreign and domestic financial institutions. The interest rates of these long-term borrowings dollars are at a fixed rate, which was 2.093% per year as of December 31, 2007. We did not pledge any of our assets as of December 31, 2007.

Our credit facilities for long-term borrowings include certain provisions that would trigger a requirement for early payment. Under the terms of our credit facilities for long-term borrowings, we are also required to comply with financial covenants, including current ratio and debt-equity ratio and other technical requirements. Our debt under these facilities may be accelerated if there is a default, including defaults triggered by failure to comply with these financial covenants and other technical requirements. As of December 31, 2007, we complied with all financial covenants of existing facilities. We entered into a multiple-purpose credit facility led by Mega Bank in May 2006 in the aggregate principal amount of NT$7.0 billion for the purposes of (i) refinancing certain of our long-term indebtedness and (ii) funding our capital expenditure. This facility is a mid-term credit facility expiring in May 2011. As of December 31, 2007, we had drawn NT$3,000 million (US$92.5 million) from this credit facility to refinance our then exiting indebtedness.

Transactions with Related Parties

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

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

Inflation/Deflation

The inflation rate in Taiwan was 2.3% in 2005, 0.6% in 2006 and 1.8% in 2007. We do not believe that inflation in Taiwan has had a material impact on our results of operations.

Taxation

The corporate income tax rate in Taiwan which applies to us is 25%. Based on our status as a company engaged in the semiconductor packaging business in Taiwan, we have been granted exemptions from income taxes in Taiwan because we used the proceeds raised through the offering of American depository receipts and capitalization of earning for the purpose of purchasing equipment. As permitted by Taiwan tax regulation, we can use these exemptions for five years from the date when we begin to generate income from the use of this equipment. As a result, we began to use these exemptions in 2004. These tax exemptions resulted in tax savings of approximately NT$622 million, NT$1,020 million and NT$1,184 million (US$36.5 million) in 2005, 2006 and 2007, respectively. We also benefit from other tax incentives generally available to technology companies, including tax credits ranging from 30% to 50% for research and development and employee training expenses and tax credits ranging from 7% to 11% for investment in automation equipment and technology and certain qualifying investments. Historically, these tax incentives have resulted in decreases of income tax payable by approximately NT$1,429 million, NT$1,050 million and NT$1,475 million (US$45.5 million) in 2005, 2006 and 2007, respectively. In 2005, 2006 and 2007, our effective income tax rates were 0.55%, 12.26% and 12.87%, respectively.

In June 2006, the FASB issued Interpretation No. (“FIN”) 48, “Accounting for Uncertainty in Income Taxes—An Interpretation of FASB Statement No. 109”, effective for fiscal years ending on December 15, 2006 and thereafter, which requires the recognition of the impact of a tax position in our financial statements if that position is more likely than not of being sustained on audit. Two-step process is required for the evaluation. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. The second step is to determine the amount of benefit to recognize in the financial statements if the more-likely-than-not recognition threshold is met. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. We adopted the provisions of FIN 48 in January 2007 and performed our evaluation pursuant to the interpretation.

US GAAP Reconciliation

Our financial statements have been prepared in accordance with ROC GAAP, which differs in certain significant respects from US GAAP. The US GAAP information in note 33 to the consolidated financial statements summarize the principal differences between the amounts determined in accordance with our accounting policy, which is based on ROC GAAP, and determined in accordance with US GAAP together with reconciliation of net income and shareholders’ equity from a ROC GAAP basis to a US GAAP basis. The following table shows a comparison of our net income and stockholders’ equity according to ROC GAAP and US GAAP for the periods indicated.

Employee Bonuses

Certain employees of our company are entitled to bonuses in accordance with applicable provisions of our articles of incorporation. Employee bonuses are determined at 10% of distributable retained earnings. Distributable retained earnings are calculated as retained earnings after various reserves in accordance with ROC regulations and our articles of incorporation and after appropriation for remuneration to directors. Employee bonuses may be granted in cash, shares or a combination of both. Under ROC GAAP, such bonuses are appropriated from retained earnings in the accounting period during which such shareholders’ approval is obtained. If such employee bonuses are in the form of our shares, the amount charged against retained earnings is based on the par value of the shares issued. Under US GAAP, any employee bonus expense is initially accrued at the end of the period when services are rendered, at 10% of the distributable retained earnings. When bonuses are approved by the shareholders in the subsequent year, an additional compensation expense is recorded for the difference between the par value and the fair market value of shares granted to employees. The difference between US GAAP and ROC GAAP in this area would result in adjustments to net income and shareholders’ equity as shown in the above schedules. In addition to the adjustments to net income and shareholders’ equity as shown in the above schedules, application of US GAAP on employee bonuses would also result in a reclassification from retained earnings to additional paid-in capital.

Employee Stock Option

Prior to January 1, 2006, US GAAP allowed us to use the intrinsic value prescribed by Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” (“APB 25”) for measurement of stock-based compensation expense with pro-forma disclosure of net income (loss) and earnings (loss) per share, as if the fair-value method of accounting defined in FAS No. 123 “Accounting for Stock-Based Compensation,” (“FAS 123”) were used. Under the fair-value method, compensation cost is measured at the grant date based on the value of the award and is recognized over the service period, which is usually the vesting period. Effective January 1, 2006, however, we adopted FAS No. 123(R) (Revised 2004), “Share-Based Payment” which eliminated the alternative to use Opinion 25’s intrinsic value method and required the use of the fair value method with forfeitures estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates. In addition, the exercise price of our stock options is subject to change due to the distribution of stock dividends. We were required to measure the effects of the modification and record incremental compensation cost, if any. For the year ended December 31, 2007, we recorded share-based compensation expense of NT$2 million (US$0.1 million) and will not continue to incur share-based compensation charges in the future period.

For computing the fair value of options granted, we use the Black-Scholes option-pricing model with input assumptions of expected volatility, expected life, expected dividend rate and expected risk-free rate of return. We apply the historical volatility based on the historical stock price volatility over the historical time period commensurate with the expected term of the employee stock options, which is based on our contractual term. We estimate dividend yield based on historical experience. In addition, we use the yield of Taiwan Government Bonds with a contract term equal to the expected term of the stock options as our risk-free interest rate pursuant to FAS No. 123 (R), which requires entities based in jurisdiction outside the United States to use the implied yield of zero coupon government bonds currently available in the market where the shares are primarily traded when estimating the risk-free interest rate.

Equity Investments

Under the equity method, our proportionate share of the income (loss) of the investee is generally recognized in the year the income (loss) is earned. However, prior to January 2005, we were permitted to delay the recognition of income (loss) until the subsequent year under ROC GAAP if financial statements of an investee are not sufficiently timely for us to apply the equity method in the current period and such equity interests are below certain materiality threshold. From January 1, 2005, we adopted the amended ROC Statement of Financial Accounting Standards No. 5, “Accounting for Long-term Equity Investment”, pursuant to which we ceased to defer the recognition of investment income of investees and recognized investment income from all investees accounted for under the equity method

based on investees’ audited financial statements for the corresponding periods. US GAAP, however, does not allow the investor company to delay recognition of its equity in the investee’s income or loss. The US GAAP adjustment deducts the delayed income from prior year’s net income and adds back delayed income to the subsequent year to arrive at net income under US GAAP.

Our proportionate share of the income (loss) from an equity investee may differ if the equity investee’s net income (loss) under ROC GAAP differs from US GAAP. Any difference would be recognized if and when we sell the equity investment.

Our proportionate share of the income or loss from an equity investee may differ from our share in the investee’s equity. Under both ROC GAAP and US GAAP, we are required to adjust our investment in correspondence to our pro rata share of the investee’s equity. Under ROC GAAP, adjustments may include, but are not limited to, cumulative translation and unrecognized pension cost. For reconciliation to US GAAP, additional adjustments are made for the variances exclusively resulting from US GAAP, such as defined benefit pension plan pursuant to SFAS No. 158.

Under a joint venture agreement with Mosel Vitelic Inc., we contributed cash as well as technological know-how in exchange for an equity interest in ChipMOS. Under ROC GAAP, we recognized as initial cost of investment for cash and the value of know-how contributed. Under US GAAP, the technological know-how transfer is not valued and not recognized as cost of investment.

Defined Benefit Pension Plan

Net periodic pension cost under US GAAP may differ from the one under ROC GAAP due to differences in, but not limited to, service cost, interest coast, expected return on assets and the amortization in net gain (loss). Reconciliation the difference between US GAAP and ROC GAAP is required before reaching US GAAP funding status.

Under ROC GAAP, pension liability is accrued without reflecting the funded status and additional minimum liability is used when the fair value of pension assets is less than the amount of accumulated benefit obligation. Under US GAAP, additional pension liability or asset is accrued pursuant to SFAS No. 158 (effective December 15, 2006), “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an amendment of FASB Statements No. 87, 88, 106, and 132(R)”, which requires the recognition of the overfunded or underfunded status of a defined benefit postretirement plan through other comprehensive income, net of tax, at the balance sheet date and eliminates the use of additional minimum liability. Gains and loss, prior service costs, or transition assets and liabilities unrecognized as components of net periodic benefit cost of the period in accordance with SFAS No. 87 are now recognized as a component of other comprehensive income.

10% Tax on Undistributed Earnings and Tax Effect of US GAAP Adjustments

Under ROC GAAP, a 10% tax on undistributed earnings is recognized as a tax expense in the period during which the amount of undistributed earnings is approved by the shareholders. Under US GAAP, the 10% tax on undistributed earnings should be accrued in the period during which the earnings are generated and should be adjusted to the extent that distributions are approved by the shareholders in the following year. Moreover, additional tax benefit (expense) and deferred tax assets or liabilities would be adjusted for the reconciled items resulting in income differences between ROC GAAP and US GAAP.

Goodwill Acquired through Acquisition

The fair value of the net assets we received was used as the value of the consideration for the acquisition of the remaining interests in Siliconware Corp. on December 31, 2000 and reflected in the common stock and capital reserve in our balance sheet. As the consideration is equal to the fair value of the net assets received, no goodwill is recorded under ROC GAAP. Under US GAAP, the acquisition has been accounted for using the purchase method of accounting, and the purchase price was determined using the market value of our shares issued in connection with the

acquisition. The difference between the fair value of our shares issued in connection with the acquisition and the fair value of the net assets acquired results in goodwill. Goodwill is amortized on a straight-line basis over ten years.

In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets,” we no longer amortize goodwill beginning 2002. We have elected to perform our annual impairment review in each fiscal year. We have completed our annual goodwill impairment test for fiscal 2005, 2006 and 2007 and concluded that there was no impairment in these three years.

Impairment of Long-lived Assets

The ROC SFAS No. 35 regarding impairment of long-lived assets is effective for financial statements issued for fiscal years ended and after December 31, 2005 and the interim periods within such fiscal years. Under both ROC GAAP and US GAAP, we are required to evaluate whether long-lived assets are subject to impairment. Impairment test is performed whenever event occurs or evidence indicates the carrying amount of an asset may not be recoverable. Under ROC GAAP, a long-lived asset is considered impaired when the anticipated recoverable amount is less than the asset’s carrying value. Recoverable amount is measured as the higher of net selling price or value in use (discounted cash flows). The difference between the recoverable amount and the carrying amount of an asset is recognized as a loss in earnings. Under US GAAP, a long-lived asset is considered impaired when the anticipated undiscounted cash flows are less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived assets. The estimate of fair value is generally based on quoted market prices from the best available information, including prices for similar assets and the results of using other valuation techniques, or discounted cash flows.

We performed periodical review for our long-lived assets and reclassifies idle assets from assets held for operating use. Idle assets are no longer used for production purposes due to technology phase out and replacement and are disposed as buyers are identified. We recognized impairment losses of NT$69 million, NT$28 million and NT$49 million (US$1.5 million), respectively, on idle assets for the years ended December 31, 2005, 2006, and 2007. No impairment was identified for other long-lived assets besides idle assets and no reconciliation for impairment loss between ROC GAAP and US GAAP were made for the years ended December 31, 2005, 2006 and 2007.

Impairment of Investments

Both under ROC GAAP and US GAAP, we evaluate our equity investments for impairment due to declines in the market value that are considered other than temporary. Such evaluations include an assessment of general economic and company-specific considerations, such as customer forecasts and regularly updated projections of operating results. In the event of a determination that a decline in the market value is other than temporary, loss is recognized in the current year’s income. The evaluation of whether a decline in market value is other than temporary requires considerable management judgment. For an investee which resolves to liquidate or dissolve, a one-time write-off will be recorded to the extent that the estimated proceeds will be obtained and the amount of investment balance will not be recovered.

In 2005, we adopted ROC SFAS 35, “Accounting for Impairment of Assets”, recognized impairment loss for investment in Double Win of NT$84 million and brought the investment balance down to nil. As a result, the impairment loss of NT$13 million of Double Win, which was recognized during 2002 under US GAAP, was reversed in 2005. We also recognized an impairment loss for investment in Artest and brought the investment balance down to nil. The impairment loss of NT$29 million was reversed in 2006.

Embedded Derivatives

Under ROC GAAP, when an issuer issues convertible bonds, the entire instrument is recorded as a liability in the amount of the proceeds received. Any discount or premium to the par value of the convertible bonds is amortized in the statement of operations by using the effective interest rate method. If the convertible bonds contain a redemption premium above their par value amount, the excess is accrued, using the effective interest rate method, over the period to redemption as a charge to interest expense. Upon conversion, the carrying value of the bonds is credited to common

stock at its par value and the difference between the carrying value of the bond and the par value of the common stock is recorded to additional paid-in capital. No gain or loss is recognized.

Under US GAAP, in accordance with SFAS 133, “Accounting for Derivative Instruments and Hedging Activities”, convertible bonds, with the feature of the combination of mutually exclusive conversion of the debt to equity or redemption at a multiple of the bonds par value, are required to be accounted for as embedded derivative instruments. In addition, if the bonds are denominated in foreign currency and conversion terms contain a fixed foreign exchange feature determining the rate at which the bonds are to be converted into local currency stock, the combination of the conversion option and the fixed foreign exchange forward contract makes the bonds dual indexed and therefore the conversion right should be bifurcated. The embedded derivatives separated from the book value of bonds are measured at fair value and changes in fair value are recognized as unrealized gain (loss) in the income statement for each accounting period.

Stock Dividends

Under ROC GAAP, an issuance of stock dividends is recorded at par with a charge to retained earnings. Under US GAAP, if the ratio of distribution is less than 25% of shares of the same class outstanding, the fair value of the shares issued should be charged to retained earnings. This different treatment will result in, under US GAAP, a reclassification from retained earnings to additional paid-in capital of NT$33,523 million (US$1,033.7 million) on December 31, 2007. This adjustment has no effect on our shareholders’ equity.

Marketable Securities

Prior to the adoption of ROC SFAS No. 34 effective January 1, 2006, marketable equity securities and long-term equity investments in which we owned less than 20% of the voting rights of a publicly listed investee company were carried at the lower of cost or market value, and debt securities at cost. The market value of listed stocks was determined by the average closing price during the last month of the accounting period. After the adoption of ROC SFAS No. 34, we are required to reclassify our equity investments into financial assets at fair value through profit or loss, available-for-sale, held-to-maturity securities or financial assets carried at costs. Unrealized gains or losses on available-for-sale securities are reported through shareholders’ equity.

Under US GAAP FAS 115, “Accounting for Certain Investments in Debt and Equity Securities”, debt and equity securities that have readily determinable fair values are to be classified as either trading, available-for-sale or held-to-maturity securities. Debt securities that we have the positive intent and ability to hold to maturity are classified as held-to-maturity securities and reported at amortized cost. Debt and equity securities that are bought and traded for short-term profit are classified as trading securities and reported at fair value, with unrealized gains and losses included in earnings. Debt and equity securities not classified as either held-to-maturity or trading are classified as available-for-sale securities and reported at fair value, with unrealized gains and losses excluded from earnings and reported in a separate component of shareholders’ equity. The fair value of listed stock under US GAAP is generally determined by the closing price at the balance sheet date. We perform impairment analysis to determine whether our marketable securities suffer a other-than-temporary decline in fair value below the cost. No such impairment has been identified during the periods presented.

Calculation of EPS

In calculating weighted average number of shares outstanding for EPS purposes under ROC GAAP, employee bonus shares have been treated as outstanding for all periods, in a manner similar to a stock split or dividend and are retroactively adjusted to previous years’ calculation of weighted-average outstanding shares. Under US GAAP, employee bonus shares have been considered separately from the stock dividend or split and have been treated as outstanding from the date when they were issued. The numbers of employee bonus shares issued in 2005, 2006 and 2007 were 1,876,500 shares, 26,779,433 shares and 35,203,522 shares, respectively.

In computing the dilutive effect of convertible bonds when calculating net income available to common stockholders for diluted EPS, the after-tax results of compensated interest expenses, unrealized foreign exchange gain/loss, amortization of bond issuance costs are taken into consideration under ROC GAAP. However, under US

GAAP, in addition to the above three items, the after tax result of mark-to-market gain or loss on embedded derivatives bifurcated from the host bonds is also taken into consideration. Anti-dilutive effect is considered both under ROC GAAP and under US GAAP.

For the purpose of computing the dilutive effect of the employee stock options, the treasury-stock method is used. Treasury shares that may be repurchased with assumed proceeds from the exercise of employee stock options may not be sufficient for the share issued upon exercising options. Therefore, incremental shares are added to the weighted average number of shares outstanding. Under ROC GAAP, the assumed proceeds are the exercise price. Under US GAAP, the assumed proceeds are the sum of (a) the exercise price, (b) the amount of compensation cost attributed to future services and not yet recognized, and (c) the amount of excess tax benefits that will be credited to additional paid-in capital assuming exercise of the options. Therefore, the amount of incremental shares calculated under US GAAP may be different from the one calculated under ROC GAAP.

Merger between Equity-Method Investees

Under ROC GAAP, we recognize our change of proportional interest in our equity-method acquired investee based on the fair value of our equity-method acquired investee’s net assets as of the acquisition date. However, under US GAAP, we recognized our change of proportional interest in our equity-method acquired investee based on the fair value of such investee’s newly issued stocks at the acquisition date.

Disposal of investment under equity method for exchange of noncontrolling ownership interest and monetary consideration

Under ROC GAAP, commercial substance, the expectation of a significant change of future cash flows, is evaluated for determining whether gain on investments should be deferred. A gain is recognized only for the portion related to the monetary consideration received. However, under US GAAP, a transaction involved significant monetary consideration that is at least 25% of the fair value exchange is deemed to be a monetary exchange. Also, Statement 153, “Exchanges of Nonmonetary Assets—an amendment of APB Opinion No. 29”, amends the scope of Opinion 29 to exclude a transfer of assets to an entity in exchange for an equity interest in that entity. Therefore, an exchange of investment would be recorded at fair value and no gain on disposal of investment would be deferred.

Recent Accounting Pronouncements

US GAAP

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurement” to define fair value, which establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosures about fair value measurements. This statement will apply whenever another statement requires or permits assets or liabilities to be measured at fair value. The standard does not expand the use of fair value in any new circumstances. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. However, in February 2008, the FASB issued FSP FAS 157-2, “Effective Date of FASB Statement No. 157” to delay the effective date of SFAS No.157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis until the beginning of the first quarter of 2009. Currently, we are evaluating the impact of adopting SFAS No.157 on those assets and liabilities subject to the delay application in accordance with FSP FAS 157-2. After evaluating the impact of the adoption of SFAS No.157, we do not expect a material impact on our consolidated financial statements.

In February 2007, the FASB issued SFAS No.159, “The Fair Value Option for Financial Assets and Financial Liabilities — Including an amendment of FASB Statement No. 115”, which permits all entities to choose, on specified election dates, to measure eligible financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings on each subsequent reporting date. SFAS 159 is effective for an entity’s fiscal year beginning after November 15, 2007. We believe that the adoption of SFAS 159 will not have any significant impact on our financial results.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), “Business Combinations”, which requires an acquirer to recognize the assets acquired, the liabilities assumed, any noncontrolling interest and contractual contingencies and contingent consideration in the acquiree at the acquisition date, measured at their fair values as of that date, with limited exceptions. It also requires that acquisition-related costs be recognized separately from the acquisition and expensed as incurred. This statement is effective for fiscal years beginning after December 15, 2008 and its effect will depend on the terms and timing of future acquisitions, if any.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51”, which requires that minority ownership interest be presented in the consolidated statement of financial position within equity, but separate from the parent’s equity. This statement is effective for fiscal years beginning on or after December 15, 2008. Currently, we do not expect any significant impact on our consolidated financial statements.

ROC GAAP

In March 2007, the Accounting Research and Development Foundation in Taiwan issued Interpretation Letter Ref. (96) 052, “Accounting for Employees’ Bonuses and Directors’ Remunerations”, which requires all entities to estimate the amount of employees’ bonuses and directors’ remunerations and record that amount as compensation expense in the period when services are rendered. Retained earnings would be no longer charged for employees’ bonuses and directors’ remunerations. This interpretation is effective for fiscal years beginning on or after January 1, 2008. In the meantime, we believe that this change will decrease our net income for the years ended December 31, 2008 and thereafter. In August 2007, the Accounting Research and Development Foundation in Taiwan issued SFAS No. 39, “Share-based Payment”, which requires an entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value. That cost will be recognized over the requisite service period in exchange for the award. No compensation cost is recognized for equity instruments for which employees do not render the requisite service. It also requires an entity to initially measure the cost of employee services received in exchange for an award of liability instruments which value is based on the current fair value of its equity investments. The compensation expense recognized over the requisite service period is subject to change due to remeasurement of the fair value of that award subsequently at each reporting date through the settlement date. This statement is effective for fiscal years beginning on or after January 1, 2008. Currently, we believe there is no significant impact on our consolidated financial statements.

Difference between NASDAQ Requirement and Home Country Practices

In general, corporate governance principles for Taiwanese companies are set forth in the ROC Company Act, the ROC Securities and Exchange Act and, to the extent they are listed on the Taiwan Stock Exchange, listing rules of the Taiwan Stock Exchange. Corporate governance principles under provisions of ROC law may differ in significant ways to corporate governance standards for U.S. NASDAQ-listed companies. Under the latest amendment to the NASD Marketplace Rule 4350(a)(1), foreign private issuers are permitted to follow certain home country corporate governance practices in lieu of the requirements of Rule 4350. Under the amendment, foreign private issuers must disclose alternative home country practices they follow. The following are the requirements of Rule 4350 we do not follow and the home country practices we follow.

Under the Rule 4350(c)(1), a majority of the board of directors must comprise of independent directors. We have three independent directors out of a total of nine directors on our board. Our standards in determining director independence substantially comply with the NASDAQ requirements, which include detailed tests for determining director independence. In Taiwan, to strengthen corporate governance of Taiwanese companies, the ROC Securities and Exchange Act Article 14-2 provides that public companies may appoint independent directors in accordance with its articles of incorporation. The government authority, however, may require a company to appoint two or more independent directors, who shall account for one-fifth or more of its total directors, depending on such company’s scale, shareholder structure, type of operations and other essential factors.

Under Rule 4350(c)(2), the company is required to have regularly scheduled meetings at which only independent directors are present. We do not hold executive sessions of non-management directors as the election of independent directors is not required by the ROC Company Act. However, once our independent directors are elected, they will participate in committee meetings of which they are committee members. In particular, we expect our independent directors to serve on our audit committee. Our audit committee will meet regularly.

Rule 4350(c)(3) requires that compensation of the chief executive officer of the company must be determined, or recommended to the board, either by a majority of the independent director or an independent compensation committee. We currently follow the practice under ROC Company Act, which requires that the compensation of directors be approved by shareholders. In addition, we also follow Article 29 of the ROC Company Act, which provides that the compensation of executive officers of the company shall be decided by resolutions adopted by the majority of the board at a meeting satisfying a quorum of more than one-half of the directors.

Under Rule 4350(c)(4), director nominees must either be selected, or recommended for the Board’s selection, either by a majority of the independent directors or an independent nominations committee. The ROC Company Act expressly grants the power of nomination to the shareholders, as well as to the board of directors. Under the ROC Company Act and the interpretations thereof, candidates to serve as directors are nominated either by the board of directors prior to the shareholders’ meeting or by the shareholders during the election of the director. Therefore, the requirement of a nominations committee is in conflict with the ROC Company Act. We currently follow the home country practice.

Under the Rule 4350(h), each issuer shall conduct a review of all related party transactions on an ongoing basis and all such transactions shall be approved by the company’s audit committee or another comparable independent body. Under Rule 4350(i)(1) (A), each issuer shall require shareholder approval when a stock option or purchase plan is to be established or materially amended or other equity compensation arrangement made or materially amended, pursuant to which stock may be acquired by officers, directors, employees, or consultants. Under the corresponding domestic requirements in the ROC Company Act and the ROC Securities and Exchange Act, shareholders’ approval is required for the distribution of employee bonuses in the form of stock, while the board of director has authority, subject to the approval of the ROC SFB, to approve employee stock option plans and to grant options to employees pursuant to such plans. We follow the home country practice. ROC law provides for specific safeguards on employee stock option grants. Options granted under the plans are subject to certain statutory volume limitations. Under the ROC Company Act, the directors of a company may not receive stock options because they are not considered “employees” of the company.

D. Employees

As of December 31, 2007, we had 16,071 full-time employees. Of these employees, 14,808 were located in Taiwan, 1,192 were located in Mainland China, and 71 were located in the United States. Employee salaries are reviewed once or twice a year. Salaries are adjusted based on industry standards, inflation and individual performance. As an incentive, additional bonuses in cash may be paid at the discretion of the management based on the performance of individuals. In addition, ROC law requires that employees be given preemptive rights to subscribe to between 10% and 15% of any of our rights issues or share offerings.

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

Our employees participate in our profit distribution under our articles of incorporation. Employees are entitled to receive bonus shares based on a percentage of our allocable surplus income. We paid employees stock in the aggregate amount of 35,203,522 shares and cash bonuses of NT$821.4 million in 2007.

In July 2002, we adopted the 2002 Employee Stock Option Plan that authorizes the grant of options to our full-time regular employees, including those of our domestic and overseas subsidiaries, for purchase up to an aggregate of 40,000,000 shares of our common shares. The exercise price for the options would be the closing price of our common shares on the Taiwan Stock Exchange on the day the options are granted, while the expiration date for such options is 5 years from the date of grant. In February and May 2003, we granted a total of 40,000 options to purchase up to 40,000,000 shares under the 2002 Employee Stock Option Plan, of which 2,950 options were granted to certain of our executive officers. Some of our executive officers receiving options are also directors of our company, and the options granted to our officers have an initial exercise price of NT$15.6 per share. The options granted in February 2003 and May 2003 had an exercise price of NT$15.6 per share and NT$16.3 per share and a purchase price of nil. In August 2004, we adjusted the exercise price of the February 2003 and May 2003 options to NT$13.7 per share and NT$14.3 per share. In August 2005, we adjusted the exercise price of the February 2003 and May 2003 options to NT$11.9 per share and NT$12.4 per share. In August 2006, we adjusted the exercise price of the February 2003 and May 2003 options to NT$9.2 per share and NT$9.7 per share, respectively, and the options will expire five years from the date of grant if not previously exercised. In August 2007, we adjusted the exercise price of the February 2003 and May 2003 options to NT$5.7 per share and NT$6.2 per share, respectively, and the options will expire five years from the date of grant if not previously exercised.


Number of shares issuable
upon exercise of options		Expiration Date	Exercise price

	1,107,500	February 2008	NT$5.7
	407,000	May 2008	NT$6.2

As of March 31, 2008, no option rights remained outstanding.

Under the 2002 Employee Stock Option Plan, an option holder may exercise an increasing portion of his or her options starting two years after the grant of the options. According to the vesting schedule, 30%, 70% and 100% of such option holder’s options shall vest two, three and four years after the grant of the options, respectively. Upon termination of employment, the option holder shall exercise his or her vested options within one month, subject to exceptions provided therein, and otherwise after the termination, such options shall terminate. If termination of employment was due to death, the heirs of such option holder have one year starting from the date of the death to exercise his or her vested options. If termination of employment was due to retirement or occupational casualty, the option holder or his or her heirs may exercise all his or her options within certain period as provided. The options are generally not transferable or pledgeable by the option holders.

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

E. Share Ownership

Each of our directors, supervisors and executive officers holds our shares either directly for their own account or indirectly as the representative of another legal entity on our board of directors.

Item 8. Financial Information

A. Consolidated Statements and Other Financial Information

Please refer to Item 18 for a list of all financial statements filed as part of this annual report on Form 20-F.

Litigation

companies and their subsidiaries. Tessera alleges that some of our packaging services have infringed patents owned by Tessera and that we have breached license agreements with Tessera. In May 2007, parties stipulated a stay pending a final determination of an investigation directed against other parties (including certain co-defendants in the lawsuit) conducted by the ITC. Pursuant to the stipulation, the court has stayed the litigation. In February 2007, we filed in the U.S. PTO requests for reexamination of five patents, four of which being asserted by Tessera against us. The PTO has issued office actions in four of the reexaminations. We are vigorously defending against Tessera’s allegations. Because litigation is inherently unpredictable, we are unable to predict the results or outcome of any dispute. For further information, see “Item 4 Information on the Company—B. Business Overview—Litigation.”

(2)		Total number of Shares issued as stock dividends include Shares issued from retained earnings and from capital reserve.

(3)		We did not declare a dividend in 2002 because we incurred a net loss in 2001.

(4)		We did not declare a dividend in 2003 because our shareholders did not elect to declare such dividend, even though we generated net income in 2002.

B. Significant Changes

Our net operating revenues on a consolidated basis for the three months ended March 31, 2008 amounted to NT$1,753 million. Our net operating revenues for the first three months of 2008 are not indicative of our financial performance on either an unconsolidated or a consolidated basis for the remaining months of 2008. In addition, we cannot predict whether the demand for our services will continue to improve in the near future.

B. Memorandum and Articles of Association

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

Objects and Purpose

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

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

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

Directors

The ROC Company Act and our articles of incorporation provide that our board of directors is elected by shareholders and is responsible for the management of our services. Our board of directors is composed of nine directors. The Chairman of our board is elected by our directors. The Chairman presides at all meetings of our board of directors and also has the authority to represent us. The term of office for our directors is three years and our directors are elected by our shareholders by means of cumulative voting. The next election for all of the directors and supervisors is expected to be held in June 2008. In addition, our shareholders also elect three supervisors whose duties include investigating our services and financial condition, inspecting corporate records, calling shareholders’ meetings when our board of directors does not or cannot convene a shareholders’ meeting or when such a meeting is necessary for our benefit, representing us in negotiations with our directors and notifying our board of directors to cease acting in contravention of law, our articles of incorporation or the resolutions of our shareholders’ meetings. The supervisors cannot concurrently serve as our directors or officers. A person may serve as our director or supervisor in his personal capacity or as the representative of one of our shareholder entities. A director or supervisor who serves as the representative of a legal entity may be removed or replaced at any time, and the replacement director or supervisor may serve the remainder of the term of office of the replaced director or supervisor. Our audit committee consists of three independent auditors, including Jing-Shan Aur, Ing-Dar Liu and Hsiu-Li Liu. In order to facilitate the function of our board of directors, our audit committee and board of directors have established procedures for the complaints pursuant to Rule 10A-3(b)(3) under the Exchange Act and have established a means for communicating with the non-management members of our board of directors.

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

Shares

As of April 30, 2008, our authorized share capital was NT$36.0 billion, divided into 3.60 billion shares, of which NT$30.7 billion, divided into 3.07 billion shares, were issued and outstanding. We issued 40,000 option rights to employees according to our 2002 Employee Stock Option Plan. As of March 31, 2008, no option rights remained outstanding. Other than our shares and ADSs, we do not have any other equity interests outstanding, including any preferential subscription rights, exchangeable debt securities or warrants as of April 30, 2008. All shares presently issued are fully paid and in registered form, and existing shareholders are not obligated to contribute additional capital. The shares underlying the ADSs are fully paid, in registered form and will not be obligated by any capital calls. We generally are not permitted to directly acquire our shares, except under limited circumstances as permitted by ROC law.

New Shares and Preemptive Rights

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

Shareholders

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

Transfer of Shares

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

Shareholders’ Meetings

We are required to hold an annual ordinary shareholders’ meeting once every fiscal year and within six months after the end of each fiscal year. Our board of directors may convene an extraordinary meeting whenever the

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

Voting Rights

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

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

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

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

Dividends and Distributions

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

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

Beginning in 1999, our articles of incorporation provide that our earnings after payment of all income taxes and deduction of any past losses shall be distributed as follows:

•

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

•

payment of 1% of the balance after deducting the 10% legal reserve as remuneration to our directors and supervisors. The remaining amount may be distributed or reserved in a ratio of 10% and 90%, respectively, to our employees as their bonuses and to our shareholders as their dividends.

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

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

In addition to permitting dividends to be paid out of net income, we are permitted under the ROC Company Act to make distributions to our shareholders of additional shares by capitalizing reserves, including the legal reserve and capital surplus of premiums from issuing stock and earnings from gifts received if we do not have losses. However, the capitalized portion payable out of our legal reserve is limited to 50% of the total accumulated legal reserve and is payable only if and to the extent the accumulated legal reserve exceeds 50% of our paid-in capital.

Acquisition of Our Shares by Us

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

Under Article 28-2 of the Securities and Exchange Law, we may, by a board resolution adopted by majority consent at a meeting with two-thirds of our directors present, purchase up to 10% of our issued shares on the Taiwan Stock Exchange or by a tender offer, in accordance with the procedures prescribed by the ROC SFB, for the following purposes:

	•		to transfer shares to our employees;

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

	•		if necessary, to maintain our credit and our shareholders’ interests; provided that the shares so purchased shall be cancelled thereafter.

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

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

Liquidation Rights

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

Other Rights of Shareholders

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

appraisal rights by notifying us before the related shareholders’ meeting and/or by raising and registering their dissent at the shareholders’ meeting.

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

Voting of Deposited Securities

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

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

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

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

	•		the notice of the meeting sent by us; and

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

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

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

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

There can be no assurance that a holder will receive notice of shareholders’ meetings sufficiently prior to the date established by the depositary for receipt of instructions to enable him to give timely voting instructions.

C. Material Contracts

Immunity Agreement with Motorola, Inc.

We entered into a license agreement with Motorola in November 1996 under which Motorola licensed to us the technology for ball grid array as well as any future technology relating to ball grid array. Under the terms of the agreement, we make royalty payments based on the number of pads or balls used in our packages. This agreement will expire in December 2010.

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

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

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

D. Exchange Controls

ROC Foreign Exchange Control Statute and regulations provide that all foreign exchange transactions must be executed by banks designated to handle such business by the Ministry of Finance or by the Central Bank of China. Current regulations favor trade-related foreign exchange transactions. Consequently, foreign currency earned from exports of merchandise and services may now be retained and used freely by exporters, and all foreign currency needed for the importation of merchandise and services may be purchased freely from the designated foreign exchange banks.

Aside from trade-related foreign exchange transactions, ROC companies and resident individuals may, without foreign exchange approval, remit outside the ROC foreign currency of up to US$50.0 million (or its equivalent) and US$5.0 million (or its equivalent), respectively, in each calendar year. In addition, ROC companies and resident individuals may, without foreign exchange approval, remit into the ROC foreign currency of up to US$50.0 million (or its equivalent) and US$5.0 million (or its equivalent), respectively, in each calendar year. Furthermore, any remittance of foreign currency into ROC by an ROC company or resident individual in a year will be offset by the amount remitted out of ROC by the company or individual (as applicable) within its annual quota and will not use up its annual inward remittance quota to the extent of such offset. The above limits apply to remittances involving a conversion of NT dollars to a foreign currency and vice versa. A requirement is also imposed on all enterprises to register medium- and long-term foreign debt with the Central Bank of China.

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

E. Taxation

ROC Tax Considerations

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

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

	•		an individual who is not an ROC citizen, who owns ADSs and who is not physically present in the ROC for 183 days or more during any calendar year; or

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

Holders of ADSs are urged to consult their own tax advisors as to their particular ROC tax consequences from owning the ADSs.

Dividends

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

Capital Gains

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

Securities Transaction Tax

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

Estate and Gift Tax

ROC estate tax is payable on any property within the ROC of a deceased who is an individual, and ROC gift tax is payable on any property within the ROC donated by an individual. Estate tax is currently payable at rates ranging from 2% of the first NT$600,000 to 50% of amounts over NT$100,000,000. Gift tax is payable at rates ranging from 4% of the first NT$600,000 to 50% of amounts over NT$45,000,000. Under ROC estate and gift tax laws, common shares issued by ROC companies are deemed located in the ROC regardless of the location of the holder. It is unclear whether a holder of ADSs will be considered to hold common shares for this purpose.

Tax Treaty

The ROC does not have a double taxation treaty with the United States. On the other hand, the ROC has double taxation treaties with Indonesia, Singapore, South Africa, Australia, Vietnam, New Zealand, Malaysia,

Macedonia, Swaziland, Gambia, The Netherlands, the United Kingdom, Senegal and Sweden which may limit the rate of ROC withholding tax on dividends paid with respect to common shares in ROC companies. It is unclear whether ADS holders will be considered holders of common shares for the purposes of these treaties. Accordingly, if the holders may otherwise be entitled to the benefits of the relevant income tax treaty, the holders should consult their tax advisors concerning their eligibility for the benefits with respect to the ADSs.

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

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

	•		an individual citizen or resident of the United States;

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

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

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

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

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

	•		a dealer in securities or currencies;

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

	•		a financial institution or an insurance company;

	•		a tax-exempt organization;

	•		a regulated investment company;

	•		a real estate investment trust;

	•		a person liable for alternative minimum tax;

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

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

	•		a person owning, actually or constructively, 10% or more of our voting stock; or

	•		a U.S. holder whose “functional currency” is not the United States dollar.

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

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

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

In general, for U.S. federal income tax purposes, a U.S. person who is the beneficial owner of an ADS will be treated as the owner of the shares underlying its ADS. However, the U.S. Treasury has expressed concerns that parties involved in transactions in which depositary shares are pre-released may be taking actions that are inconsistent with the claiming of foreign tax credits by the holders of ADSs. Such actions would also be inconsistent with the claiming of the reduced rate of tax, described below, applicable to dividends received by certain non-corporate holders. Accordingly, the analysis of the creditability of ROC taxes and the availability of the reduced tax rate for dividends received by certain non-corporate holders, each described below could be affected by future actions taken by parties to whom the ADSs are released. Deposits or withdrawals of shares by U.S. holders for ADSs generally will not be subject to U.S. federal income tax.

Taxation of Dividends

Except as discussed below with respect to the passive foreign investment company rules, the amount of distributions (other than certain pro rata distributions of shares to all shareholders) you receive on your shares or ADSs, including net amounts withheld in respect of ROC withholding taxes, will generally be treated as dividend income to you if the distributions are made from our current and accumulated earnings and profits as calculated according to U.S. federal income tax principles. In determining the net amounts withheld in respect of ROC taxes, any reduction in the amount withheld on account of a ROC credit in respect of the 10% retained earnings tax imposed on us is not considered a withholding tax and will not be treated as distributed to you or creditable by you against your U.S. federal income tax. Such income will be includible in your gross income as ordinary income on the day you actually or constructively receive it, which in the case of an ADS will be the date actually or constructively received by the depositary. The amount of any distribution of property other than cash will be the fair market value of such property on the date it is distributed. You will not be entitled to claim a dividend received deduction with respect to distributions you receive from us.

With respect to U.S. holders who are individuals, certain dividends received from a foreign corporation before January 1, 2011, on shares (or ADSs backed by such shares) that are readily tradable on an established securities market in the United States may be subject to reduced rates of taxation. U.S. Treasury Department guidance indicates that our ADSs, which are listed on the NASDAQ, but not our shares, are readily tradable on an established securities market in the United States. Thus, we do not believe that dividends that we pay on our shares that are not backed by ADSs currently meet the conditions required for these reduced tax rates. There can be no assurance that our ADSs will continue to be readily tradable on an established securities market in later years (or that our shares will be readily tradable on an established securities market in any given year). Individuals that do not meet a minimum holding period requirement during which they are not protected from the risk of loss or that elect to treat the dividend income as “investment income” pursuant to Section 163(d)(4) of the Code will not be eligible for the reduced rates of

taxation regardless of the trading status of our shares or ADSs. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. Holders should consult their own tax advisors regarding the application of these rules given their particular circumstances.

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

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

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

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

Taxation of Capital Gains

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

If you pay any ROC securities transaction tax, such tax is not treated as an income tax for U.S. federal income tax purposes, and therefore will not be a creditable foreign tax for U.S. federal income tax purposes. However, subject

to limitations under the Code, such tax may be deductible. You are urged to consult your tax advisors regarding the U.S. federal income tax consequences of these taxes.

Passive Foreign Investment Company

Based on the composition of our income and valuation of our assets, including goodwill, we do not believe we were a passive foreign investment company (“PFIC”) for 2007 and do not expect to become one in the future, although there can be no assurance in this regard.

In general, a company is considered a PFIC for any taxable year if either:

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

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

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

Our determination that we were not a PFIC in 2007 is based on a current valuation of our assets, including goodwill. In calculating goodwill, we have valued our total assets based on our total market value, which is based on the market value of our shares and is subject to change. In addition, we have made a number of assumptions regarding the amount of this value allocable to goodwill. We believe our valuation approach is reasonable. However, it is possible that the Internal Revenue Service will challenge the valuation of our goodwill, which may also result in us being classified as a PFIC.

In addition, the determination of whether we are a PFIC is made annually. Accordingly, it is possible that we may become a PFIC in the current or any future taxable year due to changes in our asset or income composition. Because we have valued our goodwill based on the market value of our shares, a decrease in the price of our shares may result in our becoming a PFIC.

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

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

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

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

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

If we are a PFIC for any taxable year and any of our foreign subsidiaries is also a PFIC, a U.S. Holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the

application of these rules. You are urged to consult your tax advisors about the application of the PFIC rules to any of our subsidiaries.

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

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

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

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

U.S. holders who are individuals will not be eligible for reduced rates of taxation on any dividends received from us prior to January 1, 2011, if we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year. You should consult your own tax advisors concerning the U.S. federal income tax consequences of holding our shares or ADSs if we are considered a PFIC in any taxable year.

Information Reporting and Backup Withholding

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

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

Inheritance and Gift Tax

Certain ROC inheritance and gift taxes may be imposed on holders of ADSs. You should consult your own tax advisor regarding the effect of such taxes on your particular situation.

Item 11. Quantitative and Qualitative Disclosures About Market Risk

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

Foreign Exchange Risk

Substantial portions of our revenues and expenses are denominated in currencies other than the NT dollar. In 2007, sales in the amount of US$1,390 million were denominated in US dollars. In 2007, material purchases from our overseas vendors in the amounts of US$362.94 million and ¥10,518.25 million were denominated in US dollars and Japanese yen, respectively. As of December 31, 2007, we had certificates of deposit, bank deposits and accounts receivable denominated in US dollars of US$280.13 million. As of December 31, 2007, we also had accounts payable, bonds payable and other liabilities denominated in US dollars and the Japanese yen of US$145.61 million and of ¥3,425.97 million, respectively. Our foreign currency revenues in general exceed our foreign currency expenses. We use the policy of natural hedging to reduce our foreign exchange exposure arising out of changes in the rates of exchange among the Japanese Yen, the US dollar and the NT dollar.

Interest Rate Risk

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

The table below presents annual principal amounts due and related weighted average interest rates by year of maturity for our debt obligations outstanding as of December 31, 2007.

Item 14. Material Modifications to the Rights of Security Holders and Use of Proceeds

See “Item 10. Additional Information” for a description of the rights of securities holders, which remain unchanged.

Item 15. Controls and Procedures

Disclosure Controls and Procedures

As of December 31, 2007, an evaluation has been carried out under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding the required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

Management’s Annual Report on Internal Control over Financial Reporting

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2007 using the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO criteria”). Based on this assessment, our management concluded that our internal control over financial reporting was effective as of December 31, 2007. The effectiveness of internal control over financial reporting has been audited by PricewaterhouseCoopers, an independent registered public accounting firm, which also audited our consolidated financial statements for the year ended December 31, 2007, as stated in their report included on page F-2.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the year ended December 31, 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 16A. Audit Committee Financial Expert

Jing-Shan Aur is our audit committee financial expert and an independent director. See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Audit Committee.”

Item 16B. Code of Ethics

We have adopted a code of ethics which applies to our directors, employees and officers, including our Chief Executive Officer and Chief Financial Officers (our principal accounting officer). No changes have been made to the code of ethics since its adoption and no waivers have been granted therefrom to our directors or employees. We have filed this code of ethics as an exhibit to our annual report on Form 20-F for the fiscal year ended December 31, 2003, which exhibit is incorporated by reference as an exhibit to this annual report, and a copy is available to any shareholder upon request.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of
Siliconware Precision Industries Co., Ltd.

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, of changes in stockholders’ equity and of cash flows present fairly, in all material respects, the financial position of Siliconware Precision Industries Co., Ltd. and its subsidiaries at December 31, 2007 and December 31, 2006, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2007 in conformity with “Rules Governing the Preparation of Financial Reports by Securities Issuers”, “Business Entity Accounting Law”, “Regulation on Business Entity Accounting Handling” and accounting principles generally accepted in the Republic of China (“ROC GAAP”). Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 15. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits (which were integrated audits in 2007 and 2006). We did not audit the financial statements of ChipMOS Technologies Inc., an investee accounted for under the equity method, which statements reflect total assets of NT$38,635,027 thousand as of December 31, 2006, and total revenues of NT$19,824,561 thousand and NT$14,756,563 thousand for each of the two years in the period ended December 31, 2006. Those statements were audited by other auditors whose report thereon has been furnished to us, and our opinion expressed herein, insofar as it relates to the amounts included for ChipMOS Technologies Inc., is based solely on the report of the other auditors. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States) and auditing standards generally accepted in the Republic of China. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Accounting principles generally accepted in the Republic of China vary in certain significant respects from accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Notes 33 and 34 to the consolidated financial statements.

As discussed in Note 3, commencing from January 1, 2005, the Company adopted Statement of Financial Accounting Standard No. 35, “Accounting for Asset Impairment” and amended Statement of Financial Accounting Standard No. 5, “Accounting for Long-term Equity Investment”, under which the Company ceased to delay in recognition of investment income of investees accounted for under the equity method until the subsequent year, and recognized investment income from all investees accounted for under the equity method based on investees’ audited financial statements for the same period. Commencing from January 1, 2006, the Company adopted amended Statement of Financial Accounting Standard No. 34, “Accounting for Financial Instruments”, and No. 36, “Disclosure and Presentation of Financial Instruments”.

Also discussed in Note 9, before January 1, 2005, the Company delayed recognition of investment income (loss) for certain investee companies accounted for under the equity method until subsequent year under ROC GAAP. Accordingly, investment income of NT$650,508 thousand was recognized as cumulative effects of changes in accounting principles based on the investees’ financial statements for the year ended December 31, 2004.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

2.		Summary of Significant Accounting Policies

		The accompanying consolidated financial statements are prepared in conformity with the “Rules Governing the Preparation of Financial Reports by Securities Issuers”, “Business Entity Accounting Law”, “Regulation on Business Entity Accounting Handling” and generally accepted accounting principles in the Republic of China. Accounting principles generally accepted in the Republic of China vary in certain significant respects from accounting principles generally accepted in the United States. The application of accounting principles in the United States would have affected the determination of consolidated net income expressed in New Taiwan dollars, for each of the three years ended December 31, 2007 and the determination of consolidated shareholders’ equity

F-11

SILICONWARE PRECISION INDUSTRIES CO., LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(EXPRESSED IN THOUSANDS OF DOLLARS, EXCEPT EARNINGS PER SHARE)

and consolidated financial position also expressed in New Taiwan dollars, as of December 31, 2006 and 2007 to the extent summarized in Note 33 to the consolidated financial statements.

The Company’s significant accounting policies are summarized as follows:

Basic of Consolidation

The Company adopted the Statement of Accounting Standards No. 7, “Consolidated Financial Statements”, which requires an entity to consolidate all of the subsidiaries which it owns, directly or indirectly, more than 50% of the voting rights and which it owns, directly or indirectly, less than 50% of the voting rights but has effective control. Significant inter-company transactions and balances between the Company and its subsidiaries are eliminated.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingencies at the date of the financial statements and the reported amounts of revenues, costs of revenue and expenses during the reporting period. Actual results may differ from those estimates.

Translation of Foreign Currency Transactions on Subsidiaries’ Financial Statements

The financial statements of foreign subsidiaries are translated into New Taiwan dollars using the spot rate as of each balance sheet date for asset and liability accounts, average exchange rate for profit and loss accounts, spot rate for dividend and historical exchange rates for equity accounts. The cumulative translation effects for subsidiaries using functional currencies other than the New Taiwan dollar are included in the “cumulative translation adjustment” in stockholders’ equity.

Foreign Currency Transactions

The Company and its subsidiaries maintain their accounts in New Taiwan dollars and their functional currencies, respectively. Transactions denominated in foreign currencies are translated into functional currencies at the exchange rates prevailing on the transaction dates. Assets and liabilities denominated in foreign currencies are translated into functional currencies at the exchange rates prevailing at the balance sheet date. Exchange gains or losses arising from the aforementioned translations are recognized in the current year’s results.

Convenience Translation into US Dollars

The Company maintains its accounting records and prepares its financial statements in New Taiwan (“NT”) dollars. The United States (“US”) dollar amounts disclosed in the 2007 financial statements are presented solely for the convenience of the reader and were translated at the rate of NT$32.43 (in dollars) to US$1.00 (in dollars), the U.S. Federal Reserve Bank of New York noon buying exchange rate on December 31, 2007. Such translation amounts are unaudited and should not be construed that the NT dollar amounts represent, or have been, or could be, converted into US dollars at that or any other rate.

Classification of current and non-current assets /liabilities

Assets that meet one of the following criteria are classified as current assets; otherwise they are classified as non-current assets:

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

	(2)		Assets held mainly for trading purposes;

	(3)		Assets that are expected to be realized within twelve months from the balance sheet date;

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

Liabilities that meet one of the following criteria are classified as current liabilities; otherwise they are classified as non-current liabilities:

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

	(2)		Liabilities arising mainly from trading activities;

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

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

Accounts Receivable

Accounts receivable expected to be collected over one year are recorded at present value by using predetermined interest rate whereas those expected to be collected within one year are not reported at present value due to the fact that the difference between the maturity value and the fair value discounted by implicit interest rate is immaterial and the frequency of transactions is high.

Allowance for Doubtful Accounts

The allowance for doubtful accounts is estimated based on the evaluation of collectibility and aging analysis of notes receivables, accounts receivable and other receivables.

Allowance for Sales Discounts

The allowance for sales discounts is provided based on the estimated allowance to be incurred and is recorded as deduction of accounts receivable.

Inventories

Inventories are recorded at cost when acquired under a perpetual inventory system and are stated at the lower of aggregate cost, determined by the weighted-average method and total inventory approach, or market value at the balance sheet date. The market values of raw materials and supplies are determined on the basis of replacement cost, while market values of finished goods and work in process are determined on the basis of net realizable value. The allowance for loss on obsolescence and decline in market value is recorded based on inventory aging and obsolescence, when necessary.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(EXPRESSED IN THOUSANDS OF DOLLARS, EXCEPT EARNINGS PER SHARE)

Available-for-sale securities

Investments in equity securities are recorded at the transaction date, rather than settlement date. Available-for-sale securities are measured at fair value at balance sheet date with changes in fair value recorded as adjustments to the shareholders’ equity. The accumulated adjustments of unrealized gain or loss are realized in earnings in the period when the financial assets are disposed. Fair values of listed securities are measured at their closing price at balance sheet date. The Company recognizes impairment loss whenever there is objective evidence of impairment. Subsequent recovery of such impairment loss shall be recorded as adjustments to shareholder’s equity rather than current earnings.

Financial assets carried at cost

Equity securities measured at fair value along with transaction costs are recorded at the transaction date. Equity securities without quoted market values are recorded at cost. The Company recognizes impairment loss whenever there is objective evidence of impairment. Such impairment loss shall not be reversed when the fair value of the asset subsequently increases.

Long-term Investments Accounted for under Equity Method

	A.		Long-term equity investments in which the Company owns at least 20% of the voting rights of the investee companies are accounted for under the equity method, unless the Company cannot exercise significant influence over the investee company. The excess of the acquisition cost over the investee’s fair value of the identifiable net assets acquired is capitalized as goodwill and tested for impairment annually. No prior period adjustment is required for the amortization in previous years. Long-term equity investments in which the Company holds more than 50% of the voting stocks or has controlling interests over the investee companies are included in the annual and semi-annual consolidated financial statements.

	B.		Unrealized gains and losses from transactions between the Company and investee companies accounted for under the equity method are deferred. Profit (loss) from sales of depreciable assets between the investee and the Company is amortized to income over the assets’ economic service lives. Unrealized gain from other types of intercompany transactions is reported as deferred credits classified as current or non-current liabilities.

	C.		When the Company’s proportional interest in an equity investee changes after the equity investee issues new shares, the effect of change in the Company’s holding ratio on long-term investment is adjusted to capital reserve. If capital reserve account is insufficient, the effect is then charged to retained earnings.

	D.		The Company’s proportionate share of the foreign investee’s cumulative translation adjustments related to the translation of the foreign investee’s financial statements into New Taiwan dollars is recognized as “Cumulative Translation Adjustments” in the stockholders’ equity.

Property, Plant and Equipment

	A.		Property, plant and equipment are stated at historical cost. Interest incurred relating to the construction of property, plant and equipment is capitalized and depreciated accordingly.

	B.		Depreciation is provided on the straight-line method over the assets’ estimated economic service lives, plus an additional year as the salvage value. Salvage values of fixed assets which are still in use after reaching their estimated economic service lives are depreciated over their new estimated remaining service lives. The service

F-14

SILICONWARE PRECISION INDUSTRIES CO., LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(EXPRESSED IN THOUSANDS OF DOLLARS, EXCEPT EARNINGS PER SHARE)

lives of fixed assets are 3 to 25 years, except for buildings, which are 35 to 55 years.

	C.		Maintenance and repairs are expensed as incurred. Significant renewals and improvements are capitalized and depreciated accordingly. When fixed assets are disposed, their original cost and accumulated depreciation are removed from the corresponding accounts, with gain or loss recorded as non-operating income or loss.

	D.		Idled assets are stated at the lower of book value or net realizable value and are reclassified to other assets. Differences between book value and net realizable value are reported as losses in current earnings.

Deferred Charges

The costs of computer software system purchased externally and tooling costs are recognized as deferred charges and amortized on the straight-line basis over the useful lives of 2 to 10 years. Convertible bond issuance costs are amortized over the period of the bonds.

Land Use Right

The rental cost for Siliconware Technology (Suzhou) Limited to lease the land from the local government is recognized as land use right and amortized on the straight-line method over the contract periods of 50 to 70 years.

Bonds Payable

According to Interpretation letter ref. (95) 078, “Compound Financial Instrument with Multiple Embedded Derivatives Issue”, issued by R.O.C. Accounting Research and Development Foundation (ARDF), the Company’s accounting policies for its convertible bonds issued on or prior to December 31, 2005 are as follows:

	A.		The excess of the stated redemption price over the par value is recognized as interest expense and compensation interest payable using the effective interest method during the period from the issuance date to the last day of the redemption period.

	B.		When a bondholder exercises his/her conversion rights, the book value of bonds is credited to common stock at an amount equal to the par value of the stock and the excess to capital reserve; no gain or loss is recognized on bond conversion.

	C.		The related issuance costs of convertible bonds are recorded as deferred charges and amortized over the period of the bonds.

	D.		For convertible bonds with redemption options, the right of redemption becomes invalid if the bondholder fails to exercise his/her redemption right upon expiration. The balance of the compensation interest payable is amortized over the period from the date following the expiration date to the maturity date using the effective interest method. However, if the fair value of common stocks, which would have been converted on the expiration date of the redemption right, is higher than the redemption price, compensation interest should be reclassified from the liability to additional paid-in capital.

	E.		The convertible bonds with redemption options are classified as current or non-current liabilities based on the date of redemption.

F-15

SILICONWARE PRECISION INDUSTRIES CO., LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(EXPRESSED IN THOUSANDS OF DOLLARS, EXCEPT EARNINGS PER SHARE)

Pension Cost

Under a defined benefit plan, the net pension cost is computed based on the results of the actuarial report. The unrecognized net asset or net obligation at transition is amortized over 15 years on a straight-line basis. Under a defined contribution plan, the Company makes contributions to employees’ individual pension accounts during the employees’ service periods. These contributions are recorded as pension costs in the current period.

Income Tax

	A.		The Company computes its income tax based on the income before tax. In accordance with ROC SFAS No. 22, “Accounting for Income Taxes”, the income tax effect resulting from temporary differences and investment tax credits is recorded as deferred income tax assets or liabilities using the asset and liability method. Deferred tax assets or liabilities are further classified into current or noncurrent and carried at net balance. Valuation allowance on deferred tax assets is provided to the extent that it is more likely than not that the tax benefit will not be realized.

	B.		The Company adopted ROC SFAS No. 12, “Accounting for Investment Tax Credits”, in determining the investment tax credits. The investment tax credits relating to the acquisition cost of qualifying equipment or technology, qualifying research and development expenditure, qualifying personnel training expenditure and qualifying investments in significant technology companies are recognized as income tax adjustments in the period the tax credits arise.

	C.		Over or under provisions of prior years’ income tax liabilities are included in the current period’s income tax expense.

	D.		The Taiwan imputation tax system requires that any undistributed earnings in domestic consolidated entities be subject to an additional 10% corporate income tax, which is recognized as tax expense at the time when the stockholders resolve the distribution of retained earnings.

	E.		Pursuant to the ROC Alternative Minimum Tax Act effective on January 1, 2006, the domestic consolidated entities are required to calculate Alternative Minimum Tax (AMT), a supplemental 10% tax on taxable income including most income that is exempted from regular income tax under various legislations, in addition to the regular tax. If the amount of alternative minimum tax is greater than that of the regular tax, the excess amount shall be reported as current tax expense.

Revenue Recognition

Revenues are recognized when services are provided based on transaction terms and when collectibility is reasonably assured.

Research and Development

Research and development costs are expensed as incurred.

Employee Stock Option Plan

According to Interpretation letter ref. (92) 072, “Accounting for Employee Stock Option Plans”, issued by the Accounting Research and Development Foundation, or “ARDF”, the Company adopts intrinsic value method for the recording of compensation expenses.

F-16

SILICONWARE PRECISION INDUSTRIES CO., LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(EXPRESSED IN THOUSANDS OF DOLLARS, EXCEPT EARNINGS PER SHARE)

Treasury Stock

	A.		The Company records treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock and as a reduction of shareholders’ equity.

	B.		Upon subsequent disposal of the treasury stock, the excess of the proceeds from disposal over the book value, determined by the weighted-average method, is credited to capital reserve. However, if the book value of the treasury stock exceeds the proceeds from disposal, the excess is first charged against capital reserve arising from treasury stock and the remainder, if any, is charged against retained earnings.

	C.		Stock of the Company held by the subsidiaries is treated as treasury stock. Subsidiaries’ gain on disposal of the Company’s stock and the cash dividend income received from the Company are recorded as additional paid-in capital — treasury stock.

Earnings Per Share

	A.		Basic earnings per share is calculated by dividing net income by the weighted average number of shares outstanding during the period. Diluted earnings per share is calculated by taking into consideration additional common shares that would have been outstanding if the equivalent diluted shares had been issued at the beginning of the year and the related gain or loss incurred from the aforementioned conversion.

	B.		The Company’s dilutive potential common shares are employee stock options and convertible bonds. In computing the dilutive effects of the employee stock options and convertible bonds, the Company applies the treasury stock method and if-converted method, respectively.

Impairment Loss of Non-financial Assets

	A.		The Company recognizes impairment loss whenever an event occurs or evidence indicates the carrying amount of an asset exceeds its recoverable amount. Recoverable amount is measured as the higher of net selling price or value in use. Net selling price is the amount obtainable from the sale of an asset in an arm’s-length transaction after deducting any direct incremental disposal costs. The value in use is the present value of estimated future cash flows expected to arise in its remained useful life.

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

Effects of Changes in Accounting Principle

Effective January 1, 2005, the Company adopted Statement of Financial Accounting Standards No. 35, “Accounting for Assets Impairment” in the Republic of China. As a result of the adoption of SFAS No. 35, total assets and shareholders’ equity decreased by NT$163,650 as of December 31, 2005 and net income decreased by NT$163,650 for the year ended December 31, 2005. As a result of recognition of impairment loss, basic earnings per share decreased by NT$0.07 (in dollars) for the year ended December 31, 2005.

SILICONWARE PRECISION INDUSTRIES CO., LTD. AND SUBSIDIARIES

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

	B.		Effective January 1, 2005, the Company ceased to delay in recognizing investment income (loss) from certain equity-method investees in accordance with the amended Statement of Financial Accounting Standards No. 5, “Accounting for Long-term Equity Investment” in the Republic of China. The cumulative effect attributable to this change in accounting principle for the year ended December 31, 2005 was NT$650,508, which was based on the investees’ financial statements for the year ended December 31, 2004.

	C.		Effective January 1, 2006, the Company adopted the amended SFAS No. 1, “Conceptual Framework for Financial Accounting and Preparation of Financial Statements”, SFAS No. 5, “Accounting for Long-term Equity Investment”, SFAS No. 7, “Consolidated Financial Statements”, SFAS No. 25, “Business Combinations — Accounting Treatment under Purchase Method” and SFAS No. 35, “Accounting for Assets Impairment”, which discontinued amortization of goodwill. This change of accounting principle had no effect on the financial statements.

	D.		Effective January 1, 2006, the Company adopted the newly released SFAS No. 34, “Accounting for Financial Instruments” and No. 36, “Disclosure and Presentation of Financial Instruments”. As a result, the Company’s total assets and total shareholders’ equity increased by NT$9,277,206 as of January 1, 2006 with no impact on net income and earnings per share for the year ended December 31, 2006.

	B.		Commencing from January 1, 2002, with the approval from ROC Securities and Futures Commission, or “SFB”, recognition of investment income (loss) had been delayed until the subsequent year. However, since January 1, 2005, the delay recognization of investment income is no longer allowed persuant to SFAS No. 5. The recognition of investment income (loss) for ChipMOS Technologies Inc. (“ChipMOS”) and Double Win Enterprise Co., Ltd. (“Double Win”), investees accounted for under the equity method, were delayed until the subsequent year before 2005. Therefore, the Company recognized investment income of NT$650,508 as cumulative effects of changes in accounting principles for the year ended December 31, 2005 based on ChipMOS’s and Double Win’s audited financial statements for the year ended December 31, 2004.

Other capital reserve shall be exclusively used to cover accumulated deficits. The amount of capital reserve used to increase capital is limited to 10% of the common stock each year when the Company has no accumulated deficits. The capital reserve can only be used to cover accumulated deficits when the legal reserve is insufficient to cover the deficits.

	B.		According to the Company Law of the ROC, the capital reserve is allowed to be transferred to capital one year after the registration of capitalization is approved.

19.

Retained Earnings

According to the Company’s Articles of Incorporation, current year’s earnings before tax, if any, shall be distributed in the following order:

	(1)		Pay all taxes and duties;

	(2)		Offset prior years’ operating losses, if any;

	(3)		Set aside 10% of the remaining amount after deducting (1) and (2) as legal reserve;

	B.		Among the total dividend distributed, at least 50% is distributed as cash dividend and the rest as stock dividend. The appropriation of the profit is subject to the resolution adopted by the Board and approval by the shareholders.

In the subsequent year(s), if the year-end balances of the cumulative foreign currency translation adjustment and unrealized losses on available-for-sale financial assets no longer result in a net reduction in the stockholders’ equity, the special reserve previously set aside will then be available for distribution.

Commitments and Contingencies

	A.		As of December 31, 2007, the Company and its subsidiaries’ issued but unused letters of credit for imported machinery and equipment was approximate NT$175,027.

	B.		For its future expansion, the Company and its subsidiaries entered into several contracts with a total payment of NT$1,790,307, of which a total amount of NT$280,409 has not been paid as of December 31, 2007.

	C.		The Company entered into several contracts with five foreign companies for the use of certain technologies and patents. The Company agreed to pay royalty fees based on the total number of certain products sold. Contracts are valid through January 2010, December 2010, January 2011, March 2012, and November 2014, respectively. One of the contracts is valid until all patents included in the contract expire and until both parties agree to terminate the contract.

	D.		On March 1, 2006, the Company was informed of a lawsuit brought by Tessera in the United States District Court for the Northern District of California against it, its subsidiary Siliconware USA, Inc., and five other semiconductor companies and their subsidiaries. Tessera alleged that some of the Company’s packaging services have infringed patents owned by Tessera and breached a license agreement with Tessera. In May 2007, the parties stipulated to a stay pending a final determination of an investigation directed against other parties (including certain co-defendants in the lawsuit) conducted by the ITC. Pursuant to the stipulation, the court stayed the litigation.

			Beginning in February 2007, the Company filed in the U.S. PTO requests for reexamination of five Tessera’s patents, four of which Tessera had asserted against the Company. The PTO has issued either office actions or action closing prosecution favorable for the Company in all of the reexaminations.

			On September 12, 2007, the Company, along with Siliconware USA, Inc. and three other co-defendants (and their subsidiaries) in the lawsuit, moved for a temporary restraining order, or the TRO, and a preliminary injunction prohibiting Tessera from initiating any action before the ITC against the Company for infringement of patents subject to the license agreements. On November 1, 2007, the court barred Tessera from initiating an action against the Company, Siliconware USA, or the Company’s three co-defendants before the ITC or outside of California alleging infringement of patents subject to licenses with Tessera until Tessera demonstrates that the packages accused of infringement are not under licenses. On January 11, 2008, Tessera served a draft ITC complaint on the Company alleging infringement of Tessera’s ‘977, ‘326, and ‘419 patents. On February 19, 2008, the court ruled that Tessera had demonstrated that laminate substrate packages are not under the license between the Company and Tessera. Tessera has not formally served its ITC complaint on the Company.

			Because litigation is inherently unpredictable, the Company is unable to predict the results or outcome of any dispute. Currently, the Company is unable to assess the potential liabilities arising out of Tessera’s claims due to the fact that information provided with regard to the infringement scope is insufficient.

Methods and assumptions used to estimate the fair values of financial instruments are as follows:

	(1)		Financial assets and liabilities with book value equal to fair value are cash, notes receivable, accounts receivable, other financial assets — current, refundable deposits, short-term loans, notes payable, accounts payable, income tax payable, accrued expenses, other payables, current portion of long-term debts, other current liabilities and other liabilities — others because of their short maturities.

	(2)		Available-for-sale financial assets — non-current are recorded at quoted market prices as their fair values due to the availability of the quoted price in an active market.

	(3)		Financial assets carried at cost are recorded at costs due to the lack of quoted market prices derived from the active market and the reasonable measurement for the fair value.

	(4)		The fair value of bonds payable and current portion of bonds payable is based on its quoted market price.

	(5)		The fair value of long-term loans is estimated by the discounted future cash flows. The discount rate, 2.307%, is based on the interest rate of the similar long-term loan, which the Company would have acquired.

	B.		Financial assets and liabilities with the risk of interest rate fluctuation:

			As of December 31, 2006 and 2007, the Company’s financial assets with fair value risk of interest rate

As of December 31, 2006 and 2007, the Company did not have financial assets and liabilities with cash flow risk of interest rate fluctuation.

	C.		Financial assets and liabilities whose changes in fair value are not recognized in earnings:

			The Company’s interest incomes from financial assets whose changes in fair value were not recognized in earnings were NT$396,461 and NT$368,610, respectively, for the years ended December 31, 2006 and 2007. The Company’s interest expenses from financial liabilities whose changes in fair value were not recognized in earnings were NT$130,443 and NT$90,294, respectively, for the years ended December 31, 2006 and 2007. Available-for-sale financial assets are measured at fair value at balance sheet date. For the years ended December 31, 2006 and 2007, balance of the adjustment to the shareholders’ equity due to changes in fair value were NT$4,765,318 and NT$2,085,514, respectively. Unrealized gain on available-for-sale financial assets reclassified from equity to current earnings was NT$1,519,146 for the year ended December 31, 2007.

Available-for-sale financial assets		7,883,601		4,873,284
Financial assets carried at cost		824,942		719,055

		8,708,543		5,592,339

	(1)		Market risk:

			The Company’s investments in equity instruments are exposed to the market price risk. However, the Company performs risk management controls to minimize the potential loss to an acceptable level. The Company believes that the probability of significant market risk is low.

	(2)		Credit risk:

			The Company’s investments in available-for-sale financial assets are through creditable financial institutions. The expected credit exposure to such financial institutions is low. For equity investments carried at cost, the Company has evaluated counter parties’ credit condition each time when the Company entered into investment transaction. Thus the credit risk is low.

	(3)		Liquidity risk:

			The Company’s available-for-sale financial assets are traded in active markets, which can be sold at the prices not significantly different from their market value. The Company is exposed to a greater liquidity risk for equity instruments measured at cost due to the fact that no active market exists for these instruments.

	(4)		Cash flow risk of interest rate:

			The Company’s investments in equity financial assets are non-interest related, so the cash flows from equity instruments are independent of changes in market interest rate.

	2.		Financial liabilities: debt instruments

		6,246,647		3,525,194

	(1)		Market risk:

			Debt instruments include zero-coupon convertible bonds embedded with call and put options, fixed interest rate bearing bond, short-term loans and long-term loans. The fair value changes of the Company’s US dollar denominated convertible bonds are affected by the stock price. However, the Company can minimize the market price risk by exercising the call option and reduce the foreign exchange rate exposure by maintaining equivalent amounts of assets denominated in US dollar. The Company’s long-term loans are not exposed to fair value risks because the borrowings have been issued at floating rates.

	(2)		Credit risk:

			Debt instruments issued by the Company do not have significant credit risk.

	(3)		Liquidity risk:

			The Company maintains sufficient working capital to meet its cash requirements. The Company believes that there is no significant liquidity risk.

	(4)		Cash flow risk of interest rate:

			The Company’s zero-coupon bonds, fixed interest rate bearing bonds, and fixed interest rate borrowings are not exposed to cash flow risk of interest rate. The Company’s long-term borrowings issued at floating rates may lead to changes of effective interest rate and fluctuation of future cash flow. However, the Company believes that the cash flow interest rate risk will not be significant.

33.		US GAAP Reconciliation

		The accompanying consolidated financial statements have been prepared in conformity with “Rules Governing the Preparation of Financial Reports by Securities Issuers”, “Business Entity Accounting Law”, “Regulation on Business Entity Accounting Handling” and accounting principles generally accepted in the Republic of China (“ROC GAAP”), which differ in certain material respects from generally accepted accounting principles in the United States (“US GAAP”). Such differences involve methods for measuring the amounts shown in the financial statements, as well as additional disclosures required by US GAAP.

		The following is a summary of the material adjustments to net income and shareholders’ equity, which would be required in reconciling the significant differences between ROC GAAP and US GAAP:

The significant accounting policies for the reconciliation from ROC GAAP to US GAAP is as follows:

(1)		Consolidation

		Under ROC GAAP, Statement of Accounting Standards No. 7, “Consolidated Financial Statements” requires that an entity fully consolidate all of the subsidiaries which it owns, directly or indirectly, more than 50% of the voting rights and which it owns, directly or indirectly, less than 50% of the voting rights but has effective control. Significant inter-company transactions and balances between the Company and its subsidiaries are eliminated.

		Under US GAAP, the FASB released Interpretation No. 46 (R), “Consolidation of Variable Interest Entities (revised December 2003) — an interpretation of ARB No. 51” in December 2003, which clarifies Accounting Research Bulletin No. 51, “Consolidated Financial Statements” and replaces FASB Interpretation No. 46, “Consolidation of Variable Interest Entities — an interpretation of ARB No. 51”. This interpretation requires existing unconsolidated variable interest entities (VIE) to be consolidated by their primary beneficiaries if the entities do not effectively disperse risks among parties involved. In other words, the Company would be the primary beneficiary of such entity if it absorbs a majority of the entity’s expected losses, receives a majority of its expected residual returns, or both. The Company performed analysis for VIEs and did not identify any variable interest entity pursuant to FIN No. 46 (R).

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

(2)		Compensated Absences

		Under ROC GAAP, the Company is not required to accrue for unused vacation at the end of each year. However, under US GAAP, unused vacation that can be carried over to the next year has to be accrued for at each balance sheet date to properly match the expense with the period in which the employee provided the services.

(3)		Stock-based Compensation

		Employee Stock Option

Before January 1, 2006, the Company elected to measure stock-based compensation expense using the intrinsic value method prescribed by Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” (APB 25), as interpreted, with pro-forma disclosure of net income (loss) and earnings (loss) per share, as if the fair-value method of accounting defined in FAS No. 123, “Accounting for Stock-Based Compensation,” (FAS 123) were used. Under the fair-value method, compensation cost is measured at the grant date based on the value of the award and is recognized over the service period, which is usually the vesting period. Had the Company determined the stock-based compensation expense for the Company’s stock options based upon the fair-value as determined by Black-Scholes option-pricing model at the grant date for the year ended December 31, 2005, the Company’s net income and earnings per share would have been the pro-forma amount indicated as follows:


	For the year ended
	December 31, 2005
	NT$
Net income		3,971,302
Less: Stock compensation expense		(64,825	)

Basic earnings per share (in dollars)
As reported		1.56

Pro forma		1.53


Diluted earnings per share (in dollars)
As reported		1.55

Pro forma		1.52

From January 1, 2006, the Company adopted FAS No. 123(R) (Revised 2004), “Share-Based Payment” which eliminated the alternative to use Opinion 25’s intrinsic value method and required the use of the fair value method with forfeitures estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates. In addition, the exercise price of the Company’s stock options is subject to change due to the distribution of stock dividends. The Company was required to measure the effects of the modification and record incremental compensation cost if any. For the years ended December 31, 2006 and 2007, the Company recorded share-based compensation expense of NT$27,331 and NT$2,356 and will not continue to incur share-based compensation charges for the 2002 Employee Stock Option Plan.

The following table summarizes the effects of employee stock option resulting from the application of SFAS No. 123(R):

Net effect of employee stock option on basic earnings per share (in dollars)		(0.02	)
Net effect of employee stock option on diluted earnings per share (in dollars)		(0.01	)

For computing the fair value of options granted, we use the Black-Scholes option-pricing model with input assumptions of expected volatility, expected life, expected dividend rate and expected risk-free rate of return. We applied the historical volatility based on the historical stock price volatility over the historical time period commensurate with the expected term of the employee stock option. The expected term is based on our contractual term. We estimated dividend yield by historical experience. Besides, we used the yield of Taiwan Government Bond with the contract term equal to the expected term of the share options as our risk-free interest rate pursuant to SFAS No. 123 (R), which required entities based in jurisdiction outside the United States to use the implied yield of zero-coupon government bonds currently available in the market where the shares are primarily traded when estimating the risk-free interest rate. The fair value of the Company’s stock options used to compute the 2005, 2006, and 2007 compensation expense is the estimated present value at grant date using the Black-Scholes option pricing model with the following weighted average assumptions:


Volatility		59.96% ~67.12 %

Risk-free interest rate		1.70% ~3.04 %

Expected holding period		3 ~ 5 years

Dividend yield		0%

Note 1: No options granted in 2006 and 2007.

	(i)		Remuneration to directors

			The Company’s Articles of Incorporation require a cash remuneration payment to its directors. Under ROC GAAP, such payments are charged directly to retained earnings for the period in which shareholders approve such payment. Under US GAAP, such cash payments should be recorded as compensation expense in the period when services are rendered.

	(ii)		Employee bonuses

			Certain employees of the Company are entitled to bonuses in accordance with applicable provisions of the Company’s Articles of Incorporation. Employee bonuses are set at 10% of distributable retained earnings. Distributable retained earnings are calculated as retained earnings after various reserves have been made in accordance with ROC regulations and the Company’s Articles of Incorporation and after appropriation for remuneration to directors. Employee bonuses may be granted in cash, shares, or a combination of both. Regardless of the form of the bonus, however, the shareholders are required by the Article of Incorporation to approve a 10% of distributable earnings as the employee bonus whenever there is a dividend distribution. Under ROC GAAP, such bonuses are appropriated from retained earnings in the period shareholders’ approval is obtained. If such employee bonuses are settled through the issuance of shares of the Company, the amount charged against retained earnings is based on the par value of the common shares issued. Under US GAAP, employee bonus expense is initially accrued at the end of the period when services are rendered, at 10% of the distributable retained earnings, which is considered the minimum liability the Company has to pay. When bonuses are approved by the shareholders in the subsequent year, an additional compensation expense is recorded for the difference between the par value and the fair market

value of shares granted to employees. The difference between US GAAP and ROC GAAP in this area would result in adjustments to the Company’s net income and shareholders’ equity as shown in reconciliation tables set forth at the beginning of this note. This accounting treatment for employees is based on the guidance of the US SEC Staff Paper entitled “International Reporting and Disclosure Issues in the Division of Corporate Finance dated November 1, 2004”. The Board of Directors of the Company resolved to distribute employee bonuses of NT$731,079 from 2005 earnings in 2006 and NT$1,173,450 from 2006 earnings in 2007. In addition to the adjustments to net income and shareholders’ equity as shown in the above schedules, the application of US GAAP to employee bonuses would also result in a reclassification from retained earnings to additional paid-in capital of NT$5,305,136 and NT$7,210,702 for the years ended December 31, 2006 and 2007, respectively.

(4)		Equity Investments

		Under both ROC and US GAAP, investments representing at least twenty percent of the voting interest of each investee for which the Company exercises significant influence over operating and financial policies are generally accounted for under the equity method. However, there are the following differences in applying equity accounting under ROC and US GAAP.

	(i)		Timing difference

			Under the equity method, the Company’s proportionate share of the income (loss) of the investee is generally recognized in the year the income (loss) is earned. Under ROC GAAP, if financial statements of an investee are not prepared in a sufficiently timely manner to enable the Company to apply the equity method currently and such equity interests are below certain materiality thresholds, the Company was permitted to delay the recognition of income (loss) until the subsequent year. However, effective January 1, 2005, the Company ceased to delay in recognizing investment income (loss) from certain equity-method investees in accordance with the amended Statement of Financial Accounting Standards No. 5, “Accounting for Long-term Equity Investment” in the Republic of China. Under US GAAP, there are no provisions that allow the investor company to delay recognition of its equity in the investees’ income or loss. The US GAAP adjustment is to adjust the timing difference by deducting the delayed income/loss recognized under ROC GAAP and adding the current year’s investment income/loss to arrive the net income under US GAAP. No timing difference occured for the year 2006 and thereafter.

	(ii)		Net income (loss) variance between US GAAP and ROC GAAP

			The Company’s proportionate share of the income (loss) from an equity investee may differ if the equity investee’s net income (loss) under ROC GAAP differs from US GAAP, resulting in differences in the carrying amount of the equity investment reported under ROC GAAP and US GAAP. The differences between ROC GAAP and US GAAP for the equity investees include, but are not limited to, accounting for compensation, joint venture accounting, embedded derivatives, deferred tax, and compensated absences.

	(iii)		Technology and know-how contributed to a joint venture investee

			In 1997, the Company established a joint venture, ChipMOS. Both SPIL and its joint venture partner contributed cash as well as “technological know-how” to the joint venture. The Company contributed cash in the amount of NT$1.4 billion. The technological know-how contributed was not carried on the Company’s balance sheet and was valued at NT$0.1 billion, a deemed value agreed to by both parties.

			Under ROC GAAP, the Company recognized an initial cost of investment for NT$1.5 billion for cash and the value of know-how contributed. The value of know-how was recognized as a deferred gain under other liabilities and was amortized over a period during which the know-how transfer was completed and implemented.

			Under US GAAP, generally, an investor initially records its joint venture investment at cost (i.e. the amount of cash contributed or net book value of non-cash assets contributed) and a gain should not be recognized on receipt of an interest in a joint venture if some or all of the investors’ interest was received for the know-how contributed. Therefore, under US GAAP, the Company initially recorded its joint venture investment at the amount of cash contributed of NT$1.4 billion, and did not recognize the deemed value for the know-how contributed. In addition, the excess of the Company’s cost of investment of NT$1.4 billion over the Company’s proportionate share of fair value of ChipMOS’ identifiable net assets is being amortized over a period of 5 years under US GAAP. Effective January 1, 2002, Statement of Financial Accounting Standards (SFAS) No. 142 requires that we cease amortization for the difference between the cost of an investment accounted for under the equity method and the amount of underlying equity in net assets of the investee. The difference between the cost of the investment and the amount of underlying equity in net assets of ChipMOS was fully written off in 2002.

	(iv)		Adjustment for the variances between net income and shareholders’ equity under US GAAP

			The Company’s proportionate share of the income (loss) from an equity investee may differ from its share in the investee’s equity. Under both ROC GAAP and US GAAP, the Company is required to adjust its investment in corresponded to its pro rata share of the investee’s equity. Under ROC GAAP, adjustments may include, but are not limited to, cumulative translation and unrecognized pension cost. For reconciliation to US GAAP, additional adjustments are made for the variances exclusively resulting from US GAAP, such as defined benefit pension plan pursuant to SFAS No. 158.

(5)

Defined Benefit Pension Plan

	(i)		Net periodic pension cost variance between US GAAP and ROC GAAP

			The Company’s net periodic pension cost under US GAAP may differ from the one under ROC GAAP due to differences in, but not limited to, service cost, interest cost, expected return on assets and the amortization in net gain (loss). Reconciliation of the difference between US GAAP and ROC GAAP is required before reaching US GAAP funding status.

	(ii)		Adjustment for the US GAAP funding status

			Under ROC GAAP, pension liability is accrued without reflecting the funded status and additional minimum liability is used when the fair value of pension assets is less than the amount of accumulated

benefit obligation. Under US GAAP, additional pension liability or asset is accrued pursuant to SFAS No. 158 (effective December 15, 2006), “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an amendment of FASB Statements No. 87, 88, 106, and 132(R)”, which requires the recognition of the overfunded or underfunded status of a defined benefit postretirement plan through other comprehensive income, net of tax, at the balance sheet date and eliminates the use of additional minimum liability. Gains and loss, prior service costs, or transition assets and liabilities unrecognized as components of net periodic benefit cost of the period in accordance with SFAS No. 87 are now recognized as a component of other comprehensive income.

(6)		10% Tax on Undistributed Earnings and Tax Effect of US GAAP Adjustments

		Under ROC GAAP, a 10% tax on undistributed earnings is recognized as a tax expense in the year of shareholders’ approval. Under US GAAP, the 10% tax on undistributed earnings should be accrued during the period the earnings generated and adjusted to the extent that distributions are approved by the shareholders in the following year. Moreover, additional tax benefit (expense) and deferred tax assets or liabilities would be adjusted for the reconciled items resulting in income differences between ROC GAAP and US GAAP. For the years ended December 31, 2005, 2006 and 2007, total amounts of tax benefit (expense) reconciled from ROC GAAP to US GAAP were NT$2,450, NT$ (17,529) and NT$24,336, of which nil, NT$(22,446) and NT$22,446 were adjusted for the undistributed earnings.

(7)		Earnings Per Share (EPS)

		In calculating weighted average number of shares outstanding for EPS purposes under ROC GAAP, employee bonus shares have been treated as outstanding for all periods, in a manner similar to a stock split or dividend, and are retroactively adjusted to previous years’ calculation of weighted-average outstanding shares. Under US GAAP, employee bonus shares have been considered separately from the stock dividend or split and have been treated as outstanding from the date when they were issued. The numbers of employee bonus shares issued in 2005, 2006, and 2007 were 18,765,500 shares, 26,779,433 shares, and 35,203,522 shares, respectively.

		In computing the dilutive effect of convertible bonds when calculating net income available to common stockholders for diluted EPS, the after-tax results of compensated interest expenses, unrealized foreign exchange gain/loss, amortization of bond issuance costs are taken into consideration under ROC GAAP. However, under US GAAP, in addition to the above three items, the after tax result of mark-to-market gain or loss on embedded derivatives bifurcated from the host bonds is also taken into consideration. Anti-dilutive effects are not adjusted for both under ROC GAAP and under US GAAP.

		For the purpose of computing the dilutive effect of the employee stock option, the treasury-stock method is used. Treasury shares that could be repurchased with assumed proceeds from the exercise of employee stock options might not be sufficient for the share issued upon exercising options. Therefore, incremental shares are added to the weighted average number of shares outstanding. Under ROC GAAP, the assumed proceeds are the exercise price. Under US GAAP, the assumed proceeds is the sum of (a) the exercise price, (b) the amount of compensation cost attributed to future services and not yet recognized, and (c) the amount of excess tax benefits that would be credited to additional paid-in capital assuming exercise of the options. Therefore, the amount of incremental shares calculated under US GAAP would be different from the one calculated under ROC GAAP.

(8)		Marketable Securities

		Before the adoption of ROC FAS No. 34, effective January 1, 2006, marketable equity securities and long-term equity investments in which the Company owns less than 20% of the voting rights of a publicly listed investee company are carried at the lower of cost or market value, and debt securities at cost. The market value of listed stocks is determined by the average closing price during the last month of the accounting period. After the adoption of newly released statement, the Company is required to reclassify its equity investments into financial assets at fair value through profit or loss, available-for-sale, held-to-maturity securities or financial assets carried at costs. Unrealized gains or losses on available-for-sale securities are reported through shareholders’ equity.

		Under US GAAP FAS 115, “Accounting for Certain Investments in Debt and Equity Securities”, debt and equity securities that have readily determinable fair values are to be classified as either trading, available-for-sale or held-to-maturity securities. Debt securities that the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity securities and reported at amortized cost. Debt and equity securities that are bought and traded for short-term profits are classified as trading securities and reported at fair value, with unrealized gains and losses included in earnings. Debt and equity securities not classified as either held-to-maturity or trading are classified as available-for-sale securities and reported at fair value, with unrealized gains and losses excluded from earnings and reported as a separate component of shareholders’ equity. The fair value of listed stock under US GAAP is generally determined by the closing price at the balance sheet date. For individual securities classified as either available-for-sale or held-to-maturity, the Company performs an analysis to determine whether a decline in fair value below cost is other than temporary. No such impairment has been identified during the periods presented.

(9)		Goodwill Acquired from Merger

		Under ROC GAAP, the fair value of the net assets we received was used as the value of the consideration for the acquisition of the remaining interests in Siliconware Corporation on December 31, 2000 and reflected in the common stock and capital reserve in our balance sheet. As the consideration is equal to the fair value of the net assets received, no goodwill is recorded.

		Under US GAAP, in connection with acquisition of Siliconware Corporation in 2000, the Company recorded net assets and goodwill of NT$5,415,439, respectively, based on independent appraisal report. Prior to the adoption of SFAS No. 142, goodwill was amortized on straight-line basis over ten years. Effective January 1, 2002, the Company adopted SFAS No. 142 and ceased amortization of goodwill and performed the annual impairment analysis using a fair value approach. As of December 31, 2007, the net carrying amount of goodwill was NT$4,873,500 and no impairment of goodwill was identified during 2005 to 2007.

(10)		Stock Dividends

		Under ROC GAAP, an issuance of stock dividend is recorded at par with a charge to retained earnings. Under US GAAP, if the ratio of distribution is less than 25 percent of shares of the same class outstanding, the fair value of the shares issued should be charged to retained earnings. This different treatment results, under US GAAP, in a reclassification from retained earnings to additional paid-in capital of NT$30,346,758

F-65

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

and NT$33,522,702 at December 31, 2006 and 2007, respectively. These adjustments have no effect on shareholders’ equity.

(11)

Impairment of Long-lived Assets and Equity Investments

	(i)		Impairment of long-lived assets

			Under both ROC GAAP and US GAAP, the Company is required to valuate whether long-lived assets are subject to impairment. Impairment test is performed whenever event occurs or evidence indicates the carrying amount of an asset may not be recoverable.

			Under ROC GAAP, ROC SFAS No. 35, “Accounting for Assets Impairment”, effective for fiscal years ended on and after December 31, 2005 and interim period within the fiscal year, a long-lived asset is considered impaired when the anticipated recoverable amount is less than the asset’s carrying value. Recoverable amount is measured as the higher of net selling price or value in use (discounted cash flows). The difference between the recoverable amount and the asset’s carrying amount is recognized as a loss in earnings.

			Under US GAAP, a long-lived asset is considered impaired when the anticipated undiscounted cash flows are less than the asset’s carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived assets. The estimate of fair value is generally based on quoted market prices, on the best available information, including prices for similar assets and the results of using other valuation techniques, or discounted cash flows.

			The Company performs periodical review for its long-lived assets and reclassifies idle assets from assets held for operating use. Idle assets are no longer used for production purposes due to technology phase out and replacement and are disposed as buyers are identified. These assets are reported at the lower of carrying amount or fair value less cost to sell. The impairment losses on idle assets for the years ended December 31, 2005, 2006, and 2007 were NT$68,766, NT$27,672 and NT$48,528, respectively. No impairment was identified for other long-lived assets besides idle assets and no reconciliation for impairment loss between ROC GAAP and US GAAP were made for the years ended December 31, 2005, 2006 and 2007.

	(ii)		Impairment of equity investments

			Both under ROC GAAP and US GAAP, the Company valuates its equity investments for impairment due to declines in the market value that are considered other than temporary. Such valuations include an assessment of general economic and company-specific considerations, such as customer forecasts and regularly updated projections of operating results. In the event of a determination that a decline in market value is other than temporary, loss is recognized in the current year’s income. The valuation of whether a decline in market value is other than temporary requires considerable management judgment. For an investee who resolves to liquidate or dissolve, a one-time write-off would be recorded to the extent that the estimated proceeds would be obtained and the amount of investment balance would not be recovered.

			During 2005, the Company adopted ROC SFAS 35, “Accounting for Assets Impairment “, performed quarterly reviews for determining whether long-term investments accounted for under equity method had been impaired and recognized impairment loss for Double Win of NT$84,450, bringing the investment

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(EXPRESSED IN THOUSANDS OF DOLLARS, EXCEPT EARNINGS PER SHARE)

balance down to nil. Therefore, the impairment loss of NT$13,260 of Double Win, which was recognized during 2002 under US GAAP, was reversed in 2005. Impairment loss on investment in Artest was recognized under ROC GAAP and decreased the carrying amount to nil. Therefore, the impairment loss of NT$28,885 was reversed in 2006.

(12)		Embedded Derivative — The Company’s Accounting as an Issuer

		Under ROC GAAP, when an issuer issues convertible bonds, the entire instrument is recorded as a liability at an amount equal to the proceeds received. Any discount or premium to the par value of the convertible bond is amortized in the statement of operations by using the effective interest rate method. If the convertible bonds contain a redemption premium above their par value amount, the excess is accrued, using the effective interest rate method, over the period to redemption as a charge to interest expense. Upon conversion, the carrying value of the bond is credited to common stock at its par value and the difference between the carrying value of the bond and the par value of the stock is recorded to additional paid-in capital. No gain or loss is recognized.

		Under US GAAP, in accordance with SFAS 133, “Accounting for Derivative Instruments and Hedging Activities”, the conversion feature embedded in a bond does not have to be separately accounted for as a derivative at fair value, if the feature is indexed only to the issuer’s own stock and would otherwise be classified in stockholders’ equity in the issuer’s statement of financial position (the “Scope Exception”).

		The Company issued zero-coupon convertible bonds on January 28, 2002 amounting to US$200,000 (the “2002 Bonds”). The 2002 Bonds are denominated in US dollars and allow the bondholders to redeem at 105.9185% of their par value on July 29, 2004. The premium put option and the conversion option are treated as a single-compound derivative instrument. Further, under US GAAP, the embedded feature with the combination of mutually exclusive choices, i.e., conversion of the debt to equity or redemption at a multiple of the 2002 Bonds par value, does not qualify for the Scope Exception. Additionally, our 2002 Bonds allow bondholders to convert into either the Company’s common stock which is traded on the Taiwan Stock Exchange (denominated in New Taiwan Dollar) or into the Company’s ADSs, which are traded on NASDAQ (denominated in US Dollars). The conversion terms contain a fixed foreign exchange feature determining the rate at which the bonds are to be converted into New Taiwan Dollar stock. As a result of the combination of the conversion option and the fixed foreign exchange rate, the 2002 Bonds are dual indexed and therefore not eligible for the Scope Exception. On February 5, 2004, the Company issued zero-coupon convertible bonds amounting to US$200,000 (the “2004 Bonds”). Similar to the 2002 Bonds, the 2004 Bonds permit the bondholders to convert those bonds into either the Company’s New Taiwan Dollar shares or ADSs resulting in those bonds being dual indexed and also not eligible for the Scope Exception. Both the compound embedded derivative in the 2002 Bonds and the embedded conversion option in the 2004 Bonds are accounted for as derivative instruments in accordance with FAS 133 with changes in fair value recognized in the income statement. The Company also recognized interest expense of NT$431,962, NT$240,446, and NT$27,715 arising from the amortization of bond discount and loss on subsequent conversion and/or buyback of convertible bonds of NT$4,442, NT$945,956 and NT$1,131,897, respectively, for the years ended December 31, 2005, 2006 and 2007.

		For the years ended December 31, 2005, 2006 and 2007, the net loss recognized from applying derivative accounting amounting to NT$2,422,617, NT$2,986,828 and NT$1,181,410, respectively.

(13)		Merger between Sigurd and Universal

		Universal Communication Technology Inc. (Universal), an equity-method investee of the Company, was merged into Sigurd Microelectronics Corp. (Sigurd), another equity-method investee of the Company, on March 1, 2005. Under ROC GAAP, the Company recognized its change of proportional interest in Sigurd based on the fair value of Universal’s net assets at the acquisition date. However, under US GAAP, the Company recognized its change of proportional interest in Sigurd based on the fair value of Sigurd’s newly issued stocks at the acquisition date.

(14)		Disposal of ChipMOS Technologies Inc. with Subscription of ChipMOS Technologies (Bermuda) Ltd.

		On March 27, 2007, the Company disposed its common stock ownership in ChipMOS Technologies Inc., or “ChipMOS”, and acquired common stock ownership in ChipMOS Technologies (Bermuda) Ltd., or ChipMOS Bermuda, the parent company of ChipMOS Technologies Inc., through private stock offering. Under ROC GAAP, the Company evaluated whether this exchange had commercial substance, which was the expectation of significant change of the future cash flows of the Company, and concluded that no such significant change would be expected. Therefore, the Company recognized gain on disposal of investment of NT$793,492 for the year ended December 31, 2007 and deferred the recognition of gain on disposal of NT$279,843 until the investment in ChipMOS Bermuda is disposed. However, under US GAAP, this transaction involved significant monetary consideration which was at least 25% of the fair value exchange was deemed to be a monetary exchange in accordance with EITF 01-02, “Interpretations of APB Opinion No. 29”. Also, the transfer of our ownership in ChipMOS with ChipMOS Bermuda for its equity interest was excluded from the scope of APB Opinion No. 29, “Accounting for Nonmonetary Transactions” pursuant to SFAS No.153, “Exchanges of Nonmonetary Assets - an amendment of APB Opinion No. 29". Therefore, the Company recorded the exchange in fair value and included deferred gain under the ROC GAAP in its U.S. GAAP earnings for the year ended December 31, 2007.

34. Additional Disclosure Required by US GAAP

	(1)		Risks and Uncertainties

			The Company is a provider of subcontract IC assembly and testing services. The Company’s revenues are derived primarily from precision dicing of silicon wafers into individual ICs, mounting and wire bonding ICs to lead frames, and sealing ICs in molded plastic packages. The Company’s other products include a variety of turnkey services, including the grinding of wafers to specified thickness, function testing of packaged ICs, and drop shipment to customers of the IC manufactures. The Company provides its services on a global basis but mainly to customers in Taiwan of 35.5% and North America of 57.2% in 2007. The Company’s first two largest customers accounted for a total of 21%, 18% and 21 % of net sales in 2005, 2006 and 2007, respectively, and its five largest customers accounted for 42%, 40% and 41% of the Company’s total sales in 2005, 2006 and 2007, respectively.

			In 2005, 2006 and 2007, significant portion of the Company’s net operating revenue was denominated in U.S. dollars. On the other hand, in 2005, 2006 and 2007, significant portion of the Company’s purchase were incurred in U.S. dollars and in Japanese Yen. The Company’s capital expenditures are generally

F-68

SILICONWARE PRECISION INDUSTRIES CO., LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(EXPRESSED IN THOUSANDS OF DOLLARS, EXCEPT EARNINGS PER SHARE)

denominated in U.S. dollars and Japanese Yen. The Company did not hedge any portion of the resulting net foreign exchange position and would be affected by the fluctuations in U.S. dollar, Japanese Yen and other currencies.

Substantially all of the Company’s accounts receivables are due from companies in high technology industries located primarily in Asia and North America. Further, the five largest receivables amounted to NT$3,392,955 and NT$4,441,005 as of December 31, 2006 and 2007, respectively. The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. Receivables are generally due within 90 days.

Other factors that could affect the Company’s future operating results and cause actual results to vary materially from historical results include, but are not limited to, dependence on the highly cyclical nature of both the semiconductor and the personal computer industries, competitive pricing and declines in average selling prices, availability of manufacturing capacity, dependence on raw materials and competition.

	(2)		Maturity of Long-term Liabilities

			Aggregate maturities for the Company’s long-term loans as of December 31, 2007 are as follows:


Years ending December 31,	Amounts
	NT$		US$

2008		—		—
2009		750,000		23,127

2011		750,000		23,127
2012		—		—

		3,000,000		92,507

	(3)		Uncertainty in Income Taxes

			Effective for fiscal years beginning after December 15, 2006, the FASB Interpretation No. (“FIN”) 48,” Accounting for Uncertainty in Income Taxes—An Interpretation of FASB Statement No. 109”, requires the recognition of the impact of a tax position in our financial statements if that position is more likely than not of being sustained on audit. This interpretation also prescribes measurement of a tax position taken or expected to be taken in a tax return and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.

			The Company adopted the two-step evaluation process required by this interpretation. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. The second step is to determine the amount of benefit to recognize in the financial statements if the more-likely-than-not recognition threshold is met. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. As a result of the evaluation, the Company did not recognize any cumulative effect adjustment to the retained earnings at the beginning of the year 2007. As of December 31, 2007, there was no material uncertain tax position or unrecognized tax benefit identified by the Company.

Employers’ Disclosure about Pension Benefit

(i)

As of December 31, 2006, the Company adopted the provisions of SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)”, which impacted the Company’s balance sheet at December 31, 2006 as follows:


	Before application					After application

Total stockholders’ equity		65,068,672		(209,558	)		64,859,114

			In accordance with SFAS No. 158, the Company’s 2005 accounting and related disclosures were not affected by the adoption of the new standard.

	(ii)		The following tables set forth the actuarial assumptions, funded status and amounts recognized for the Company’s defined benefit pension plan pursuant to SFAS No. 87 and SFAS No. 158:

(1)

Assumptions:


	For the years ended December 31,
	2006			2007
Discounted rate		3.25	%		2.75	%

Long-term rate of compensation increase		2.00	%		2.00	%

Expected rate of return on plan assets		3.25	%		3.00	%

			In determining the discount rate, SFAS No. 87, “Employer’s Accounting for Pensions”, recommends some factors for consideration, including: (a) rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the pension benefits; and (b) rates implicit in current prices of annuity contracts that could be used to effectively settle the pension obligation. Since Taiwan bond market does not have a deep market for corporate bonds, the yield rates of government bonds with duration years of 15 years or more are mainly used in determining the discount rate.

	(iii)		Valuation and allocation of plan assets

			securitized products. The Company does not have authority on how to invest the money. The plan assets increase by the Company’s contributions, account interest earned and profit sharing of the portfolio of BOT pension assets and decrease by the payments made to the retired employees.

	(iv)		Additional disclosures under FAS132 (R) regarding pension benefits are as follows:

	A.		Estimated future benefit payments:

			The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid:


	Amounts
	NT$		US$
2008		8,562		264
2009		8,205		253

2012		25,195		777
Year 2013 to 2017		221,615		6,834

	B.		Contributions:

			The Company expects to contribute NT$55,148 to its pension plan in 2008.

	(7)		Inventory Provision

			The Company evaluates its inventory based on the lower of cost or market value (LCM) and records inventory at market by allowance method, which an allowance account and a loss account are established for the inventory write-downs in the period in which the loss occurs. Balance of the allowance account is reversed and a gain on the recovery of loss on obsolescence and decline in market value of inventory is recognized only when the inventory is sold or disposed. The accounting treatment under ROC GAAP is identical to which under US GAAP.

	(8)		Revenue Recognition Accounting Policy

			The Company derives its revenues from the provision of independent assembly, testing services, and turnkey services and recognizes service revenues upon shipment or upon completion of various stages of turnkey services, based upon transaction terms and when collection is reasonable assured, which is essentially the same under US GAAP. If turnkey services are negotiated in one contract, the Company recognizes revenues based on the quoted prices when all of the revenue recognition criteria are met.

	(9)		Sales Returns

			The Company derives revenues only from providing independent testing and assembly services to semiconductor companies. As the Company does not engage in product sales, it does not account for sales returns.

	(10)		Major Debt Covenants

			The major covenants of the Company’s long-term loans are as follows:

	a.		Current ratio should be larger than 100%.

	b.		Liability to equity ratio should be lower than 100%.

	c.		Interest coverage ratio should be larger than 400%.

	(11)		Operating Leases

			The Company entered into three lease contracts with Science Park Administration for the use of land of the facility located in Hsinchu, Taiwan. None of these three contracts have met any of the four criteria classified as capital leases and no noncancelable lease terms are included in the leases. Rental expenses recorded for the years ended December 31, 2005, 2006, and 2007 were NT$7,760, NT$9,055, and NT$10,300, respectively.

(13)		Recent Accounting Pronouncements

	US GAAP

	A.		In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurement” to define fair value, which establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosures about fair value measurements. This statement will apply whenever another statement requires or permits assets or liabilities to be measured at fair value. The standard does not expand the use of fair value in any new circumstances. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. However, in February 2008, the FASB issued FSP FAS 157-2, “Effective Date of FASB Statement No. 157” to delay the effective date of SFAS No.157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis until the beginning of the first quarter of 2009. Currently, we are evaluating the impact of adopting SFAS No.157 on those assets and liabilities subject to the delay application in accordance with FSP FAS 157-2. After evaluating the impact of the adoption SFAS No.157, the Company does not expect a material impact on its consolidated financial statements.

	B.		In February 2007, the FASB issued SFAS No.159, “The Fair Value Option for Financial Assets and Financial Liabilities — Including an amendment of FASB Statement No. 115”, which permits all entities to choose, on specified election dates, to measure eligible financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings on each subsequent reporting date. SFAS 159 is effective for an entity’s fiscal year beginning after November 15, 2007. The adoption of SFAS 159 is expected not to have any significant impact on the Company’s financial results.

	C.		In December 2007, the FASB issued SFAS No. 141 (revised 2007), “Business Combinations”, which requires an acquirer to recognize the assets acquired, the liabilities assumed, any noncontrolling interest and contractual contingencies and contingent consideration in the acquiree at the acquisition date, measured at their fair values as of that date, with limited exceptions. It also requires that acquisition-related costs be recognized separately from the acquisition and expensed as incurred. This statement is effective for fiscal years beginning after December 15, 2008 and its effect will depend on the terms and timing of future acquisitions, if any.

	D.		In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51”, which requires that minority ownership interest be presented in the consolidated statement of financial position within equity, but separate from the parent’s equity. This statement is effective for fiscal years beginning on or after December 15, 2008. Currently, the Company does not expect any significant impact on the adoption of SFAS No. 160 on its consolidated financial statements.

ROC GAAP

	A.		In March 2007, the ROC Accounting Research and Development Foundation issued Interpretation Letter Ref. (96) 052, “Accounting for Employees’ Bonuses and Directors’ Remunerations”, which requires all entities to estimate the amount of employees’ bonuses and directors’ remunerations and record that amount as compensation expense in the period when services are rendered. Retained earnings would be no longer charged for employees’ bonuses and directors’ remunerations. This interpretation is effective for fiscal years beginning on or after January 1, 2008. In the meantime, the Company believes that this change will decrease our net income for the years ended December 31, 2008 and thereafter.

	B.		In August 2007, the ROC Accounting Research and Development Foundation issued SFAS No. 39,” Share-based Payment”, which requires an entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value. That cost will be recognized over the requisite service period in exchange for the award. No compensation cost is recognized for equity instruments for which employees do not render the requisite service. It also requires an entity to initially measure the cost of employee services received in exchange for an award of liability instruments which value is based on the current fair value of its equity investments. The compensation expense recognized over the requisite service period is subject to change due to remeasurement of the fair value of that award subsequently at each reporting date through the settlement date. This statement is effective for fiscal years beginning on or after January 1, 2008. Currently, the Company believes there is no significant impact on its consolidated financial statements.

The Board of Directors and Shareholders ChipMOS TECHNOLOGIES INC.		Tel: 886 2 25629889 Fax: 886 2 25815955 E-Mail: tpe@moorestephens.com.tw

We have audited the accompanying consolidated balance sheets of ChipMOS TECHNOLOGIES INC. and subsidiaries (collectively the “Company”) as of December 31, 2005 and 2006, and the related consolidated statements of operations, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2006, all expressed in New Taiwan dollars. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the Republic of China and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2005 and 2006, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006, in conformity with accounting principles generally accepted in the Republic of China.

Accounting principles generally accepted in the Republic of China vary in certain significant respects from accounting principles generally accepted in the United States of America. The application of the latter would have affected the determination of net income (loss) for each of the three years in the period ended December 31, 2006, and the determination of shareholders’ equity and financial position as of December 31, 2005 and 2006, to the extent summarized in Note 25.

1. GENERAL

ChipMOS TECHNOLOGIES INC. (ChipMOS Taiwan) was incorporated on July 28, 1997 as a joint venture company of Mosel Vitelic Inc. (MVI) and Siliconware Precision Industries Co. Ltd. (SPIL). Its operations, which began on August 12, 1997, consist of research, development, manufacturing, testing, and assembly of integrated circuits, LCD and other Flat-Panel Display Driver Semiconductors. ChipMOS Taiwan also provides semiconductor testing and assembly services on a turnkey basis, in which ChipMOS Taiwan purchases fabricated wafers and sells tested and assembled semiconductors to application and system manufacturers.

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 to ChipMOS TECHNOLOGIES (Bermuda) LTD. (ChipMOS Bermuda) in exchange for 58,342 thousand newly issued common shares of ChipMOS Bermuda. The selling shareholders, who previously held in an aggregate 70.25% of the outstanding common shares of ChipMOS Taiwan, thus, became the holders of the entire outstanding common shares of ChipMOS Bermuda. As of December 31, 2006, ChipMOS Bermuda owned 70.42% of the outstanding common shares of ChipMOS Taiwan.

As of December 31, 2006, ChipMOS Taiwan owned 100% of the outstanding shares of both ChipMOS Japan Inc. (ChipMOS Japan) and ChipMOS USA Inc. (ChipMOS USA), 35.62 % of ThaiLin Semiconductor Corp. (ThaiLin)

For 2004, among aforementioned entities, the accounts of ChipMOS USA and ChipMOS Japan were too nominal, so they were not included in the consolidated financial statement.

The consolidated financial statements were prepared in conformity with Guidelines for Securities Issuers’ Financial Reporting, Commercial Accounting Law, accounting principles generally accepted in Republic of China (ROC), other relevant laws and regulations. The Company significant accounting policies are summarized as follows:

Classification in the balance sheet

A year is used to classify assets/liabilities as current or non-current in the balance sheet.

Cash equivalents

Commercial papers acquired under resale agreements with original maturity dates of less than three months are classified as cash equivalents.

Financial assets

The financial assets are categorized into financial assets at fair value through profit or loss, available-for-sale, held-to-maturity financial assets, and financial assets carried at cost, etc. The financial assets are initially recognized at fair value. The transaction costs directly attributable to the acquisition of financial assets at fair value through profit and loss shall be expensed as incurred, whereas for others shall be included in the original costs.

The financial assets at fair value through profit or loss include investments for trading purpose and those designated as financial assets reported at fair value, with the subsequent changes in fair value recognized in earnings.

The available-for-sale financial assets are carried at fair value, with the subsequent changes in fair value reported as a separate component of shareholders’ equity. If there is objective evidence indicating that impairment has occurred, the impairment loss shall be recognized. For equity securities, the subsequent reversal of impairment loss shall be recorded as an adjustment of shareholders’ equity; for debt securities, the adjustment shall be recognized

in earnings, provided that the reversal is related to the event which occurred after the impairment loss was recognized.

The held-to-maturity financial assets are carried at amortized cost. If there is objective evidence indicating that impairment has occurred, the impairment loss shall be recognized. The subsequent reversal of impairment loss shall be recognized in earnings to the extent of the amortized cost, provided that the reversal is related to the event, which occurred after the impairment loss was recognized.

F-88

Investments that do not have a quoted market price in an active market and their fair value cannot be readily determinable are carried at original cost. The recognized impairment loss cannot be reversed subsequently.

Allowance for doubtful receivables

Allowance for doubtful accounts is provided based on evaluation of the collectibility of the receivables evaluated based upon the overall financial condition and payment history of the individual customers as well as the age of the receivables.

Allowances for sales returns and discounts

Allowances for sales returns and discounts are provided based on the sales returns from the past experience; such provisions are deducted from sales and the related costs of products are deducted from cost of products sold.

Inventories

Inventories are stated at the lower of standard cost (which approximates actual weighted average cost) or market value. Market value represents replacement cost for raw materials and net realizable value for other inventories.

Investments Accounted for Using Equity Method

Effective January 1, 2006, pursuant to the revised SFAS No.5 “Long-term Investments in Equity Securities”, the existing difference between the cost of investment and the Company’s share of the investee’s net equity treated as either goodwill with investment premium, has no longer being amortized; or deferred credit with negative premium, shall continue to be amortized over the remaining periods. The future difference shall be allocated to the related assets according to the method applied to identify net assets at the process of acquisition in accordance with SFAS No. 25 “Business Combination”.

Property, plant and equipment and non-operating properties

Property, plant and equipment and non-operating properties are stated at cost less accumulated depreciation. Major additions, renewals and betterment are capitalized, while maintenance and repairs are expensed currently.

The initial estimate of the service lives of the property, plant and equipment is as follows: Machinery and equipment, 1 to 6 years; buildings and auxiliary equipment, 1 to 54 years; furniture and fixtures, 1 to 5 years; tooling, 1 to 2 years; transportation equipment, 5 years; and leasehold improvements, 1 to 10 years. The foregoing service lives plus one year to represent the estimated salvage value are used to depreciate the property, plant and equipment using the straight-line method. The carrying value of property, plant and equipment, which were fully depreciated using the foregoing service lives, but are still being used by the Company are depreciated over their remaining estimated service lives.

Upon sale or disposal of items of properties, the related cost and accumulated depreciation are removed from the accounts, and any gain or loss is credited or charged to current income.

F-89

Goodwill

Goodwill arising on consolidation represents the excess of the cost of acquisition over the group’s interest in the fair value of the identifiable assets and liabilities of a subsidiary, associate or jointly controlled entity at the date of acquisition. Goodwill is recognized as an asset and not to be amortized any more since January 1, 2006.

Goodwill arising on the acquisition of an associate or a jointly controlled entity is included within the carrying amount of the associate or jointly controlled entity. Goodwill arising on the acquisition of subsidiaries is presented separately in the balance sheet.

Intangible assets

Intangible assets are amortized using the straight-line method over the following periods: Technology know-how, 5 years; technology license fee, and deferred charges, 3 to 10 years.

Revenue recognition

Sales are recognized when titles of products and risks of ownerships are transferred to customers, primarily upon shipment.

Foreign-currency transactions

Foreign-currency transactions, except derivative financial instruments, are recorded in New Taiwan dollars at the rates of exchange in effect when the transactions occur. Gains or losses resulting from the application of different foreign exchange rates when cash in foreign currency is converted into New Taiwan dollars, or when foreign-currency receivables or payables are settled, are credited or charged to income in the year of conversion or settlement. On the balance sheet dates, the balances of foreign-currency assets and liabilities are restated at the prevailing exchange rates and the resulting differences are charged to current income except those foreign currency denominated investments in shares of stock where such differences are accounted for as translation adjustments under stockholders’ equity.

Pension costs

Pension costs are recorded based on actuarial calculations. Unrecognized net transition obligation is amortized over 15 years.

Retirement benefit contributions are made to independent pension funds, Contributions are made based on a percentage of the employees’ salaries, and are charged to current income as incurred.

Income tax

The Company adopts inter-period income tax allocation method. Deferred income tax assets are recognized for the tax effects of deductible temporary differences, unused tax credits, and operating loss carry forwards and those of taxable temporary differences are

F-90

recognized as deferred income tax liabilities. Valuation allowance is provided for deferred tax assets that are not certain to be realized. A deferred tax asset or liability is classified as current or non-current based on the classification of the related asset or liability. However, if a deferred asset or liability cannot be related to an asset or liability in the financial statements, then it is classified as current or non-current based on the expected reversal dates of the temporary difference.

Any tax credit arising from the purchase of machinery, equipment and technology, research and development expenditures, personnel training, investments in important technology-based enterprise are recognized by the flow-through method.

Adjustments of prior years’ tax liabilities are added to or deducted from the current year’s tax provision.

Income taxes (10%) on unappropriated earnings generated are recorded as expense in the year when the stockholders have effectively resolved that earnings shall be retained.

With the “Income Basic Tax Act” takes effect as of January 1, 2006, the calculation base for income tax payment should be either the taxable income calculated by the “Income Tax Act” plus tax exemptions granted under other laws, taxed at rate of 10% as set by the Executive Yuan of the ROC, or that calculated in accordance with the “Income Tax Act”, which ever is higher. The Company has included this effect in the current income tax provision.

Derivative financial instruments

Foreign currency forward exchange contracts (forward contracts), entered into for purposes other than trading, are recorded as follows: the differences in the New Taiwan dollar amounts translated using the spot rates as of the contract date and the amounts translated using the contracted forward rates are amortized over the terms of the forward contracts using the straight-line method. At the balance sheet dates, the receivables or payables arising from forward contracts are restated using the prevailing spot rates and the resulting differences are recognized in income. Also, the receivables and payables related to the forward contract are netted and the resulting net amount is presented as either an asset or liability.

The aggregate amount of the foreign currency to be acquired or sold under European option contracts, entered into as hedge of anticipated transactions, is not recorded as assets or liabilities. The amounts received on options written and the amounts paid on options purchased are amortized using the straight-line method over the term of the contract. The gains arising from the exercise of the options or the losses arising from options not exercised are recognized as adjustments to the carrying values when the hedged transaction occurs.

Treasury stock

The Company adopted ROC SFAS No. 30, “Accounting for Treasury Stock”. The Company purchases its own outstanding shares and the shares of parent company held by its subsidiaries are regarded as treasury stock.

Impairment losses of assets

F-91

The Company adopted ROC SFAS No. 35, “Accounting for asset impairment” on January 1, 2005, which requires that certain assets, including properties, assets leased to others and deferred charges, are subject to an impairment review in order to look for any indication that the value of assets might be impaired on the balance date. An impairment loss should be recognized whenever the recoverable amount of the asset or the cash-generating unit is below the carrying value of an asset.

The recoverability is determined by comparing the carrying amount of the asset (or asset group) on the date it is being tested for recoverability to the higher of the net fair value of the assets or the sum of the expected net present value of future cash flows generated by the assets and eventual disposal. A cash-generating unit, which includes allocation of goodwill, shall be tested for impairment on an annual basis. The impairment loss shall first credit to the portion of goodwill, then allocate to other assets according to the proportional ratio of their book value. The recognized impairment losses of goodwill cannot be reversed.

If any evidence indicates that the impairment loss recognized in previous years has decreased, the Company shall re-perform the recoverability test and adjust the carrying value of the assets to the extent of recoverable amount. However, the adjusted carrying value of the assets due to loss reversal should not be in excess of the original book value, net of depreciation or amortization, had the impairment loss not been recognized.

After the recognition of an impairment loss, the depreciation (amortization) charged on the assets shall be adjusted in future periods by the revised carrying values of the assets (net of accumulated impairment), less their salvage value, on a systematic basis over their remaining useful lives.

Reclassifications

Certain accounts in 2004 and 2005 have been reclassified to conform to 2006 classifications.

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 at the mid-price of the USD as quoted by Bank of Taiwan as of December 31, 2006, which was NT$32.595 to US$1.00. The 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.

As of December 31, 2006, ThaiLin held 254 thousand outstanding shares of ChipMOS Taiwan as long—term investment. The treasury stocks were carried with an amount of NT$4,750 thousand, according to ChipMOS Taiwan’s equity in the cost of the investment recorded by ThaiLin.

In 2005 and 2006, ChipMOS Taiwan purchased 7,098 thousand and 210 shares of treasury stock at the cost of NT$115,402 thousand and NT$3,191 thousand, respectively.

F-104

These shares shall be transferred to employees, resold or de—registered within three years. These shares do not possess shareholder’s equity.

17. SHAREHOLDERS’ EQUITY

Under ROC Company Law, the capital surplus can only be used to offset deficits, except that capital surplus generated from (1) donations (donated capital) or (2) the excess of the issue price over the par value of capital stock (including stocks issued for new capital and mergers, and the purchase of treasury stock) can be transferred to capital as stock dividends when no deficit remains and shareholders approve such distribution.

ChipMOS Taiwan’s Articles of Incorporation provides that the following may be appropriated, from the accumulated net income after deducting any previously accumulated deficit and 10% legal reserve, subject to shareholder approval: (a) 10% as bonus to employees, (b) not more than 2% as remuneration to directors and supervisors, (c) a special reserve, if deemed necessary, and (d) dividends to shareholders.

These appropriations and the disposition of the remaining net income shall be resolved by the shareholders in the following year and given effect in the financial statements of that year.

The aforementioned appropriation for legal reserve shall be made until the reserve equals aggregate par value of ChipMOS Taiwan’s outstanding capital stock. The reserve can only be used to offset a deficit; or, when its balance has reaches 50% of the aggregate par value of the outstanding capital stock of ChipMOS Taiwan, up to 50% thereof can be distributed as stock dividend.

Under the Integrated Income Tax System that became effective on January 1, 1998, ROC resident individual shareholders are allowed a tax credit for the income paid by ChipMOS Taiwan on earnings generated from the effective date. An Imputation Credit Account (ICA) is maintained by ChipMOS Taiwan for such income tax and the tax credit allocated to each shareholder. The maximum credit available for allocation to each resident shareholder cannot exceed the balance shown in the ICA on the date of distribution of dividends.

	d.		Integrated income tax information

			ChipMOS Taiwan, the balances of the ICA were NT$52,445 thousand and NT$71,486 thousand as of December 31, 2005 and 2006, respectively.

			ChipMOS Taiwan, the imputation credit allocated to each shareholder shall be based on the balance in the ICA on the date of distribution of dividends. Tax creditable ratio was 2.85% and 1.18% for 2005 and 2006, respectively.

F-107

The balance and year of expiry of unused investment tax credits as of December 31, 2006 are as follows:


Year of Expiry	Machinery & Equipment		R&D Expenditure
	NT$		NT$
	(In Thousands)
2007		267,082		34,184
2008		254,505		—
2009		43,416		42,732
2010		476,556		—


		1,041,559		76,916

			The deferred tax assets related to the investment tax credits on R&D expenditures and purchases of machinery and equipment will expire from 2007 to 2010. Under ROC tax regulations, tax credits can be utilized to reduce current income tax obligations only to the extent of 50% of such income tax obligations except in the year when such tax credit will expire, in which case, the entire amount of expiring tax credit may be utilized to reduce the current income tax obligation. The foregoing limitation on the utilization of tax credits, the expiry dates of the tax credits, the level of tax credits expected to be generated from future operations and the level of non-taxable income attributable to the four-year income tax holiday on capacity expansion led management to conclude that it is unlikely that these investment tax credits will be fully realized. Loss carry forwards can be used to deduct current income tax obligation up to the extent of taxable income and will be expired after 5 years if not fully utilized by the Company. Accordingly, a valuation allowance on deferred tax assets is recognized as of December 31, 2005 and 2006.

			The tax authorities have examined and assessed the income tax returns of ChipMOS Taiwan and ThaiLin through 2003 and 2004, respectively.

			According to ROC tax law, unappropriated earnings generated in 1998 and thereafter are subject to a tax of 10% in the year when the shareholders resolve that such earnings shall be retained. The retained earnings (accumulated deficit) of ChipMOS Taiwan as of December 31, 2005 and 2006 were generated during and after 1998.

	g.		On April 20, 1999, ChipMOS Taiwan entered into a semiconductor packaging technology license agreement with Tessera Technologies, Inc. (Tessera). Under this agreement, ChipMOS Taiwan agreed to pay a license fee of US$500 thousand and a royalty fee at a certain percentage of the net sales of certain products. ChipMOS Taiwan paid the total license fee of approximately US$500 thousand (NT$15,888 thousand) in 1999 and amortized the amount over 5 years using the straight-line method. ChipMOS Taiwan also paid approximately US$500 thousand (NT$16,708 thousand) in 2004 as the cumulative production and sales quantity of products bearing Tessera Compliant Chip packages did not meet the commitment schedule as set in the agreement. In February 2006, ChipMOS Taiwan and ChipMOS USA have 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. According to Company’s counsel, fact discovery has been ongoing and is scheduled to close on March 31, 2007, although it may be extended beyond that date by order of the Court. Therefore, expert discovery will be continued and the trial date could be moved to April 2008. The Company’s counsel has not formed an opinion as to the outcome of the case.

Under the Agreement, ChipMOS Taiwan promised to pay royalties and licensee fees to Motorola for using certain patents owned by Motorola. Freescale replaced Motorola as a party to the Agreement, after Freescale was spun off from Motorola. Freescale has alleged that ChipMOS Taiwan breached the Agreement by failing to pay royalties on certain packages assembled by ChipMOS Taiwan. Freescale claims that such packages are covered by one or more Freescale patents identified in the Agreement while ChipMOS Taiwan contends that such packages are not covered by any patents in the Agreement, or, if covered, those patents are invalid. As such, ChipMOS Taiwan argues Freescale’s unilateral termination of the Agreement has no legal effect. ChipMOS Taiwan has continued to make royalty payments for products it believes are covered by the Agreement. Any payments returned by Freescale have been deposited in a separate escrow account. If Freescale initiates a lawsuit, ChipMOS Taiwan expect to vigorously defend itself. The Company’s counsel has not formed any opinion as to the outcome of the case.

23. DERIVATIVE FINANCIAL INSTRUMENTS

ChipMOS Taiwan had entered into forward exchange contracts or foreign currency options for the years ended December 31, 2006, to hedge its exchange rate risk on foreign-currency assets or liabilities and anticipated transactions. Information on the derivative transactions is as follows:

	a.		Forward, exchange contracts

			As of December 31, 2005 and 2006, there were no outstanding forward contracts. Net exchange gains on forward exchange contracts were NT$1,528 thousand and NT$2,257 thousand for the year ended December 31, 2005 and 2006.

F-116

	b.		European options

			ChipMOS Taiwan expects to receive U.S. dollars from its export sales and to pay Japanese yen for its importation of materials, machinery, and equipment. It has entered into foreign currency option contracts with banks to hedge exchange rate risks. As of December 31, 2005 and 2006, ChipMOS Taiwan had no outstanding foreign currency option contracts. For the years ended December 31, 2005 and 2006, ChipMOS Taiwan didn’t realize premium income of NT$36 and nil thousand, respectively.

	c.		Interest Rate Risks

			ChipMOS Taiwan has entered into interest rate swap agreements to manage interest rate risk by exchanging a quarto stepping interest rate for a floating rate and keeps records when transactions are settled. The difference of the interests is calculated quarterly and is credited or charged to the income in the current period. The benefit of interest rate swaps recognized as non-operating income in 2005 and 2006 were NT$11,190 thousand and nil respectively.

	d.		Transaction risks

	1)		Credit risk. The banks with which the Company has entered into the above contracts are reputable and, therefore, the Company does not expected to be exposed to significant credit risks.

	2)		Market risk and hedge strategy. The Company is exposed to market risks arising from changes in currency exchange rates due to U.S. dollar denominated accounts receivable, Yen denominated accounts payable and U.S. dollar denominated debt. In order to manage these exposures, the Company entered into forward contracts and option contracts occasionally.

	3)		Liquidity and cash requirements. The cash flow requirements with respect to the Company’s forward contracts are limited to the periodic premium payments and the net differences of the contracted settlement rates. On the other hand, call/put options may not have to be exercised at all in cases where the strike price is higher/lower than the related market price at exercise dates.

In providing turnkey services, the Company purchases fabricated wafers and sells tested and assembled semiconductors to application and system manufacturers. The process of conducting testing and assembling for the fabricated wafer is at a very limited level, which only uses a very small portion of facility capacity. Therefore, the Company allocated no specific assets to the turnkey segment and accordingly, no related depreciation and amortization was allocated.

The corporate and other assets constitute the total current assets, long-term investments, long-term restricted cash equivalents, intangible assets of bond issuance costs, employee dormitory building and refundable deposits.

25. SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES FOLLOWED BY CHIPMOS TAIWAN AND ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED STATES

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the Republic of China (“ROC GAAP”), which differ in the following respects from accounting principles generally accepted in the United States of America (“U.S. GAAP”):

	a.		Bonuses to employees, directors and supervisors

			According to ROC regulations and the Articles of Incorporation of ChipMOS Taiwan, a portion of distributable earnings should be appropriated as bonuses to employees and remuneration to directors and supervisors. The remuneration to directors and supervisors is paid in cash, while bonuses to employees may be granted in cash or stock or both. These appropriations, including stock bonuses, which are valued at par value of NT$10, are charged against retained earnings under ROC GAAP, after such appropriations are formally approved by the shareholders in the following year.

			Under U.S. GAAP, such bonuses and remuneration are charged to income currently and included in operating expenses as compensation expenses. Since the amount and form of such bonuses and remuneration are not finally determinable until approved by the shareholders, the total amount of such bonuses and remuneration is initially accrued based on the amount to be paid as provided by ChipMOS Taiwan’s Articles of Incorporation. The percentage to be paid in stock is determined at the next shareholders’ meeting in the following year. The number of shares to be issued is determined by dividing the amount to be paid in stock by the par value of the shares. Any difference between the initially accrued amount (the cash portion plus the par value of the shares) and the fair market value of the bonuses settled (the cash portion plus the fair value of the shares) is recognized in the year of approval by the shareholders.

	b.		Financial assets

			Prior to January 1, 2006 under ROC GAAP, marketable equity securities are carried at the lower of aggregate cost or market value, and debt securities at cost, with only unrealized losses recognized when losses are irrecoverable. Under SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities”, debt and equity securities that have readily determinable fair values are to be classified as either trading, available-for-sale or held-to-maturity securities. Debt securities that the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity securities and reported at amortized cost. Debt and equity securities that are bought and traded for short-term profit are classified as trading securities and reported at fair value, with unrealized gains and losses included in earnings. Debt and equity

F-121

securities not classified as either held-to-maturity or trading are classified as available-for-sale securities and reported at fair value, with unrealized gains and losses excluded from earnings and reported in a separate component of shareholders’ equity; however, unrealized losses relating to declines in fair value deemed to be other than temporary are recorded in earnings. The 2004 and 2005 adjustment below relates to the Company’s equity securities that are classified as trading and available-for-sale securities under U.S. GAAP. There is no difference between ROC GAAP and U.S. GAAP effective January 1, 2006.

	c.		Long-term investments

			Under both ROC and U.S. GAAP, investments in shares of companies wherein the Company owns over 20% of the outstanding common stock and exercises significant influence over operating and financial policies of the investee companies are generally accounted for under the equity method. However, there are differences in applying equity accounting under ROC and U.S. GAAP. The Company’s proportionate share of the income (loss) from an equity investee may differ if the equity investee’s net income (loss) under ROC GAAP differs from that under U.S. GAAP. The differences between ROC GAAP and U.S. GAAP for the equity investees have been adjusted and included in the reconciliation below.

			Under the equity method, the Company’s proportionate share of the income (loss) of the investee is generally recognized in the year the income (loss) is earned. However, in 2004 under ROC GAAP, if audited financial statements of an investee are not available for the Company to apply the equity method due to time constraints and such equity interests are below certain materiality threshold, the Company is permitted to delay the recognition of income (loss) until 2005. Under US GAAP, there are no provisions that allow the investor company to delay recognition of its equity in the investees’ income or loss. The US GAAP represents the proportionate share of loss of long-term investment in 2004. In 2005 and 2006, there was no such difference.

	d.		Technologies transferred in payment of capital stock

			As discussed in Note 11, MVI and SPIL contributed, as payment to their subscription in the shares of stock of ChipMOS Taiwan, technologies relating to the testing and assembly of semiconductors at an agreed value of NT$750,000 thousand. Under ROC GAAP, such technology transfers in payment of capital stock are recorded as an intangible asset, and amortized by systematic charges to income over the periods estimated to be benefited. As permitted under ROC GAAP, ChipMOS Taiwan uses a 5 years amortization period. Under U.S. GAAP, the technology contribution cannot be recognized due to the unavailability of a fair value for the technologies. Therefore, the carrying value of the technologies has been adjusted to zero under U.S. GAAP.

F-122

	e.		Start-up costs

			ROC GAAP requires start-up costs to be deferred and amortized in a systematic manner over the periods of the expected benefit. Start-up costs include all costs incurred prior to production readiness. On the other hand, U.S. GAAP primarily requires that start-up costs be expensed as incurred.

	f.		Depreciation of fixed assets and employee dormitory building

			Under ROC GAAP, the estimated life of a building can be as long as 55 years based on the ROC Internal Revenue Code. For U.S. GAAP purpose, building lives are estimated to be 25 years.

	g.		Transfer of building and facilities from MVI

			ChipMOS Taiwan purchased building and facilities from MVI in 1997. The actual costs of assets purchased from MVI were based on MVI’s book value of such building and facilities on a specified cut-off date plus an additional payment of NT$173,174 thousand representing compensation to MVI. ChipMOS Taiwan capitalized, allowed under ROC GAAP such additional payment of NT $173,174 thousand. Under U.S. GAAP, assets acquired are recorded at amounts that do not exceed their fair values. Also, generally under U.S. GAAP, the transferee should evaluate the assets transferred from related parties with significant influence at the predecessor’s basis. Therefore, the assets transferred from MVI were evaluated at MVI’s predecessor cost basis and the NT$173,174 thousand was deducted from the capital surplus and building and facilities for U.S. GAAP.

	h.		Inventory

			As discussed in paragraphs e. f. and g., the amortization of start-up costs, the depreciation on fixed assets and employee dormitory building, and the depreciation on the assets transferred from MVI were reconciled for U.S. GAAP purposes. Some of such expenses were recorded in the manufacturing expenses and therefore affect ending inventory balances under U.S. GAAP.

	i.		Capital surplus

			Under ROC GAAP, the following items are treated as capital surplus: (a) premium on issuance of common stocks; and (b) gain, net of applicable income tax, on disposal of properties. Under U.S. GAAP, item (a) is the same as in ROC GAAP; and item (b) is recorded as part of net income, which is then included as a component of retained earnings. However, starting in 2001, the treatment of item (b) under ROC GAAP has become the same as under U.S. GAAP.

	j.		Impairment of long-lived assets

			Under U.S. GAAP, impairment losses for assets to be held and used are recorded in current period earnings and create a new cost basis for related assets going forward, and cannot be reversed subsequently. Under U.S. GAAP, in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”, long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For purposes of evaluating the recoverability of long-lived assets, the recoverability test is performed by comparing undiscounted net cash flows of the assets to the net book value of the assets. If the recoverability test indicates that impairment has occurred, the impairment loss is the amount of

F-123

the asset’s net book value in excess of the related fair value. Prior to January 1, 2005, there is no requirement provided for impairment of long-lived assets under ROC GAAP. Therefore, the Company applied US GAAP to evaluate the long-lived assets for impairment purpose in 2004. In 2005, the adjustment for impairment of long-term investment represented the additional impairment to be recognized after the reversal of amortization of goodwill in respect of the long-term investment. In 2006, the adjustment represents the reversal of impairment loss recognized under ROC GAAP that were already recognized under U.S. GAAP in 2005.

	k.		Stock bonus and dividend

			Under ROC GAAP, stock bonus and dividends are recorded at par value with a charge to retained earnings. Under U.S. GAAP, if the ratio of distribution is less than 25 percent of the same class of shares outstanding, the fair value of the shares issued should be charged to retained earnings and capital surplus. Accordingly, an adjustment of NT$61,632 thousand was included in the reconciliation, representing the difference between the fair value and the par value of ThaiLin stock.

	l.		Earnings per share (EPS)

			In calculating the weighted average number of shares outstanding for EPS purposes under ROC GAAP, employee bonus shares have been treated as outstanding for all periods in a manner similar to a stock split or stock dividend. Under U.S. GAAP, employee bonus shares have been considered separately from the stock dividend or split and have been treated as outstanding from the date of shareholder approval.

	m.		Interest capitalization

			Under ROC GAAP, interests on borrowings during construction conceptually should be capitalized in the assets that are constructed or produced for a company’s own use. However, if equity capital is raised during a year, no capitalization interest is recorded for the amount of property acquired up to the equity capital raised in that year. Under

			U.S. GAAP, SFAS No. 34 “Capitalization of Interest Cost”, interest is generally capitalized on assets until they are available and ready for use.

	n.		Goodwill and negative goodwill

			Prior to January 1, 2006 under ROC GAAP, goodwill arises as the difference between acquisition cost and the equity of the subsidiary and is amortized using a systematic method, whereas under U.S. GAAP such goodwill is not amortized, but is subject to impairment tests.

F-124

			Negative goodwill arises when the fair values of the net assets acquired exceed the purchase price. Under ROC GAAP, negative goodwill is amortized over a five-year period whereas under U.S. GAAP, that negative goodwill is firstly allocated pro rata reduce amounts assigned to acquired assets. If negative goodwill still remains, it is recognized as extraordinary gain in the period in which the business combination is initially recognized. The negative goodwill of NT$20,275 thousand arising from the merger of CHANTEK into ChipMOS Taiwan was credited to property, plant and equipment under U.S. GAAP.

			There is no difference between ROC GAAP and U.S. GAAP since January 1, 2006.

	o.		Pension expenses

			ROC SFAS No. 18, which is similar in many respects to SFAS No. 87 and SFAS No. 88, was effective in 1996. However, the treatment of certain expenses that comply with ROC SFAS No. 18 is different from SFAS No. 87 and SFAS No. 88.

			The company adopted SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (“SFAS No. 158”) effective December 31, 2006. SFAS No. 158 requires an employer that sponsors one or more defined benefit pension plans or other postretirement plans to recognize the funded status of a plan, measured as the difference between plan assets at fair value and the benefit obligation in the balance sheet and recognize in shareholders’ equity as a component of accumulated other comprehensive loss, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not yet recognized as components of net periodic benefit cost as of the balance sheet date.

			The adoption of SFAS No. 158 resulted in a decrease in total shareholders’ equity of NT$63,395 thousand (US$1,945 thousand) as of December 31, 2006.

	p.		Allowance for loss and scrap loss on inventories

			ROC GAAP does not specify the classification of allowance for loss on inventories, therefore the recovery of allowance for loss on inventories of NT$67,002 thousand and NT$74,581 thousand for 2004 and 2005 has been classified under non-operating income. Under U.S. GAAP, the allowance for loss on inventories should be classified in the income statement as a component of cost of revenue.

			ROC GAAP does not specify the classification of scrap loss on inventories; therefore, in 2006, NT$75,602 thousand has been classified under non-operating expense. Under U.S. GAAP, the scrap of inventories should be classified in the income statement as a component of cost of revenue.

26. ADDITIONAL DISCLOSURES REQUIRED BY U.S. GAAP

	a.		Recent accounting pronouncements

			The Company is required by SEC Staff Accounting Bulletin No. 74 to make certain disclosures about the effect that recently issued accounting standards will have on the financial statements adopted for future periods.

			On September 29, 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (“SFAS No. 158”). SFAS No. 158 requires an employer that sponsors one or more defined benefit pension plans or other postretirement plans to 1) recognize the funded status of a plan, measured as the difference between plan assets at fair value and the benefit obligation, in the balance sheet; 2) recognize in shareholders’ equity as a component of accumulated other comprehensive loss, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not yet recognized as components of net periodic benefit cost; 3) measure defined benefit plan assets and obligations as of the date of the employer’s fiscal year-end balance sheet; and 4) disclose in the notes to the financial statements additional information about the effects on net periodic benefit cost for the next fiscal year that arise from delayed recognition of the gains or losses, prior service costs or credits, and transition asset or obligation.

			The FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments” (“SFAS No. 155”) in February 2006. SFAS No. 155 amends SFAS No. 133 “Accounting for Derivative Instruments and Hedging Activities”, and SFAS No. 140 “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities” and addresses the application of SFAS No. 133 to beneficial interests in securitized financial assets. SFAS No. 155 establishes a requirement to evaluate interests in securitized financial assets to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain an embedded derivative requiring bifurcation. Additionally, SFAS No. 155 permits fair value measurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. SFAS No. 155 is effective for fiscal years beginning after September 15, 2006. The Company is currently assessing the impact SFAS No. 155 will have on the consolidated financial statements but do not anticipate it will be material.

			The FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets an amendment of FASB Statement No. 140” (“SFAS No. 156”) in March 2006. SFAS No. 156 requires a company to recognize a servicing asset or servicing liability each time it undertakes an obligation to service a financial asset. A company would recognize a servicing asset or servicing liability initially at fair value. A company

F-130

			will then be permitted to choose to subsequently recognize servicing assets and liabilities using the amortization method or fair value measurement method. SFAS No. 156 is effective for fiscal years beginning after September 15, 2006. The Company is currently assessing the impact SFAS No. 156 will have on the consolidated financial statements but do not anticipate it will be material.

			On July 13, 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes-an Interpretation of FASB Statement No. 109” (“FIN No. 48”). FIN No. 48 clarifies what criteria must be met prior to recognition of the financial statement benefit of a position taken in an income tax return. FIN No. 48 will require companies to include additional qualitative and quantitative disclosures within their financial statements. The disclosures will include potential tax benefits from positions taken for tax return purposes that have not been recognized for financial reporting purposes and a tabular presentation of significant changes during each period. The disclosures will also include a discussion of the nature of uncertainties, factors that could cause a change, and an estimated range of reasonably possible changes in tax uncertainties. FIN No. 48 will also require a company to recognize a financial statement benefit for a position taken for tax return purposes when it will be more-likely-than-not that the position will be sustained. FIN No. 48 will be effective for fiscal years beginning after December 15, 2006. The Company is currently assessing the impact FIN No. 48 will have on the consolidated financial statements but do not anticipate it will be material.

			On September 15, 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”). SFAS No. 157 addresses how companies should measure fair value when they are required to use a fair value measure for recognition and disclosure purposes under generally accepted accounting principles. SFAS No. 157 will require the fair value of an asset or liability to be based on a market based measure, which will reflect the credit risk of the company. SFAS No. 157 will also require expanded disclosure requirements, which will include the methods and assumptions used to measure fair value and the effect of fair value measures on earnings. SFAS No. 157 will be applied prospectively and will be effective for fiscal years beginning after November 15, 2007 and to interim periods within those fiscal years. The Company is currently assessing the impact SFAS No. 157 will have on the consolidated financial statements.

			In September 2006, the U.S. SEC staff issued Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”). SAB 108 was issued to provide interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. The Company adopted the provisions of SAB 108 effective December 31, 2006. The adoption of SAB 108 did not have an impact on the consolidated financial statements.
