SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS



This annual report on Form 20-F contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as
amended. Although these forward-looking statements, which may include statements regarding our future results of operations, financial condition, or business prospects, are based on our own information and information from other sources we believe
to be reliable, you should not place undue reliance on these forward-looking statements, which apply only as of the date of this annual report. The words anticipate, believe, expect, intend,
plan, estimate and similar expressions, as they relate to us, are intended to identify a number of these forward-looking statements. Our actual results of operations, financial condition or business prospects may differ
materially from those expressed or implied in these forward-looking statements for a variety of reasons, including, among other things and not limited to, the cyclical nature of our industry, further declines in average selling prices, excess
capacity in the TFT-LCD industry, our dependence on introducing new products on a timely basis, our dependence on growth in the demand for our products, our ability to compete effectively, changes in technology and competing products, our ability to
successfully expand our capacity, our ability to acquire sufficient raw materials and key components, our dependence on key personnel, general political and economic conditions, including those related to the TFT-LCD industry, possible disruptions
in commercial activities caused by natural and human-induced disasters, including terrorist activity and armed conflict, fluctuations in foreign currency exchange rates, and other factors. For a discussion of these risks and other factors, please
see Item 3. Key InformationRisk Factors.



CERTAIN CONVENTIONS



We publish our financial
statements in New Taiwan dollars, or NT dollars, the lawful currency of the Republic of China, or the ROC. This annual report contains translations of NT dollar amounts into United States dollars, or U.S. dollars, at specific rates solely for the
convenience of the reader. For convenience only and unless otherwise noted, all translations from NT dollars to U.S. dollars and from U.S. dollars to NT dollars in this annual report were made at a rate of NT$31.74 to US$1.00, the noon buying rate
in The City of New York for cable transfers in NT dollars per U.S. dollar as certified for customs purposes by the Federal Reserve Bank of New York on December 31, 2004. No representation is made that the NT dollar or U.S. dollar amounts referred to
herein could have been or could be converted into U.S. dollars or NT dollars, as the case may be, at any particular rate or at all. On July 1, 2005, the noon buying rate was NT$31.64 to US$1.00. Any discrepancies in any table between totals and sums
of the amounts listed are due to rounding.



All references in
this annual report to Taiwan or the ROC are to the island of Taiwan and other areas under the effective control of the Republic of China, and all references to the ROC government are references to the government
of the Republic of China. All references to the our company, we, us and our in the annual report are references to AU Optronics Corp. and its consolidated subsidiaries, unless the context suggests
otherwise. All references in this annual report to the PRC or China are to the Peoples Republic of China, excluding Taiwan and the special administrative regions of Hong Kong and Macau.



All references in this annual report to large-size panels refer
to panels ten inches and above in diagonal length. All references to small- to medium-size panels refer to panels which are under ten inches in diagonal length.

ITEM 3. KEY INFORMATION



3.A. Selected Financial Data



The
selected statement of operations data for the years ended December 31, 2002, 2003 and 2004 and selected balance sheet data as of December 31, 2003 and 2004 set forth below have been derived from our audited consolidated financial statements included
herein. The selected balance sheet data as of December 31, 2000 and 2001 have been derived from our audited financial statements that have not been included herein. Our consolidated balance sheets as of December 31, 2002, 2003 and 2004 and related
consolidated statements of operations, changes in stockholders equity, and cash flows for each of the years in the three-year period ended December 31, 2004 have been audited by KPMG Certified Public Accountants, or KPMG, independent
registered public accounting firm, whose report thereon is included herein. The selected financial and operating data set forth below should be read in conjunction with Item 5. Operating and Financial Review and Prospects and the
consolidated financial statements and the notes to those statements included herein.



Our consolidated financial statements are prepared and presented in accordance with generally accepted accounting principles in the ROC, or ROC GAAP. On September 1, 2001, we completed a merger with Unipac
Optoelectronics Corporation, or Unipac, an affiliate of United Microelectronics Corporation, or UMC. Under ROC GAAP, the merger of Unipac has been accounted for under the pooling-of-interests method of accounting, whereby the historical financial
statements of the previously separate companies for periods prior to the merger have been restated on a combined basis. As a result, unless otherwise indicated, our operational and financial data, under ROC GAAP, presented herein for periods or
dates prior to September 1, 2001 represent the combined operational and financial data of our company and Unipac. In contrast, under generally accepted accounting principles in the United States, or U.S. GAAP, the merger of Unipac has been accounted
for as the acquisition of Unipac by our company under the purchase method of accounting, whereby our cost of acquiring Unipac was measured by the market value of the shares we issued to Unipac shareholders in connection with the merger plus related
acquisition costs. Such acquisition cost has been allocated to the assets of Unipac we acquired and the liabilities of Unipac we assumed, based on their fair value as of September 1, 2001. Our financial data, under U.S. GAAP, presented herein for
periods or as of dates prior to September 1, 2001, do not include the financial data of Unipac.



For information relating to the nature and effect of significant differences between ROC GAAP and U.S. GAAP as they relate to us, see note 22 to our
consolidated financial statements.

##### Table of Contents

The table below sets forth certain financial data under ROC GAAP for the periods and as of the dates
indicated. As more fully discussed above in the second paragraph of this section, such data have been prepared under the pooling-of-interests method of accounting under ROC GAAP, whereby the financial data of both our company and Unipac for the
periods and as of the dates prior to September 1, 2001, the date of the completion of our merger with Unipac, have been restated on a combined basis. The combined operational and financial data presented herein do not purport to be indicative of
what our actual operational and financial results would have been if our merger with Unipac had actually taken place on January 1, 2000 or 2001, respectively, for the purpose of presenting our statements of operations, statements of changes in
stockholders equity and statements of cash flows data for the years ended December 31, 2000 and 2001, respectively.

Exchange Rate



Fluctuations in the exchange rate between NT dollars and U.S. dollars will affect the U.S. dollar equivalent of the NT dollar price of our shares on the
Taiwan Stock Exchange and, as a result, will likely affect the market price of the ADSs. These fluctuations will also affect the U.S. dollar conversion by the depositary of cash dividends paid in NT dollars on, and the NT dollar proceeds received by
the depositary from any sale of, our shares represented by ADSs.



The following table sets forth, for the periods indicated, information concerning the number of NT dollars for which one U.S. dollar could be exchanged based on the noon buying rate for cable transfers in NT dollars as certified for customs

Risks Relating to Our
Financial Condition, Business and Industry



The
industry in which we operate is cyclical. As a result, price fluctuations in response to supply and demand imbalances could harm our results of operations.



The thin film transistor liquid crystal display, or TFT-LCD, industry in general is characterized by cyclical market
conditions. The industry has been subject to significant and rapid downturns as a result of an imbalance between excess supply and a slowdown in demand, resulting in sharp declines in average selling prices. For example, the significant increase in
the average selling prices of large-size panels in the first half of 2002 was followed by a slowdown in demand growth in the second half of 2002, which in turn resulted in excess supply in the market and caused sharp declines in prices in that
period.

##### Table of Contents

As a result, the average selling prices of our large-size panels decreased by 13.0% between the second
quarter and the third quarter of 2002 and further decreased by 21.7% between the third quarter and the fourth quarter of 2002. There was a recovery in the average selling prices of large-size panels in 2003, with average selling prices of our
large-size panels increasing by 17.3% between the first quarter of 2003 and the fourth quarter of 2003. Average selling prices of our large-size panels increased by 12.1% between the fourth quarter of 2003 and the second quarter of 2004 which was
followed by a sharp decrease of 22.2% between the second quarter and the third quarter of 2004 and a further decrease of 17.1% between the third quarter and the fourth quarter of 2004. Average selling prices of our large-size panels decreased by
6.5% between the fourth quarter of 2004 and the first quarter of 2005. Capacity expansion currently being undertaken or anticipated in the TFT-LCD industry has led to excess capacity and could continue to lead to a future period or periods of
general excess capacity in the industry. For example, it is expected that as additional capacity provided by fifth-, sixth- and future generation fabs becomes available, the TFT-LCD industry may face excess capacity. We cannot assure you that any
continuing or further decrease in average selling prices or future downturns resulting from excess capacity or other factors affecting the industry will not be severe or that any such continuation, decrease or downturn would not seriously harm our
business, financial condition and results of operations.



Our
ability to maintain or increase our revenues will be highly dependent upon our ability to maintain market share, increase unit sales of existing products, and introduce and sell new products that compensate for the anticipated fluctuation and
long-term declines in the average selling prices of our existing products. We cannot assure you that we will be able to maintain or expand market share, increase unit sales, and introduce and sell new products, to the extent necessary to compensate
for market oversupply.



We experienced a net loss in 2001
and the first quarter of 2005. Although we were profitable in 2002, 2003 and 2004, if we are not profitable in 2005 or beyond, the value of the ADSs and our shares may be negatively affected.



We experienced a net loss in 2001 and the first quarter of 2005 due
principally to a decline in the average selling prices of our products and lower utilization at our facilities caused by an oversupply of TFT-LCD panels in the market. The decline in average selling prices resulted in a decrease in our gross
margins. We expect that average selling prices for many of our existing products will continue to decline over the long term. If we are not able to reduce our costs of manufacturing these panels to offset expected declines in average selling prices
and maintain a high capacity utilization rate, our gross margin will continue to decline, which could seriously harm our business and reduce the value of our equity securities. Although we were profitable in 2002, 2003 and 2004, we cannot assure you
that we will be profitable in 2005 or beyond.



Our future net
sales, gross profit and operating income may vary significantly due to a combination of factors, including, but not limited to:



| |  |  | Our ability to develop and introduce new products to meet customers needs in a timely manner. The inability to develop or introduce new products in a timely manner may
hurt our competitive position because customers may choose to source more advanced products from competitors.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our ability to develop or acquire and implement new manufacturing processes and product technologies. If we are unable to successfully implement new manufacturing processes
and product technologies in a timely manner, our competitors may seize new opportunities in new markets.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our ability to control our fixed and variable costs and operating expenses. Increased fixed and variable costs and operating expenses may reduce our profitability and
adversely affect our results of operations.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Changes in our product mix or those of our customers. When our customers or we discontinue a product or experience production problems with new products, our results of
operations may fluctuate.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | Our ability to obtain raw materials and components at acceptable prices and in a timely manner. A shortage in raw materials and components could result in increased raw
materials and components costs and put downward pressure on gross margins as well as cause delays to our production and delivery schedules, which may result in the loss of customers and revenues.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Lower than expected growth in demand for TFT-LCD panels resulting in oversupply in the market.When oversupply conditions occur, we may reduce the price of our panels to
maintain high capacity utilization rates or reduce the volume of our production.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Our results of operations fluctuate from quarter to quarter, which makes it difficult to predict our future performance.



Our results of operations have varied significantly in the past and may fluctuate significantly from quarter to quarter in
the future due to a number of factors, many of which are beyond our control. Our business and operations may be negatively affected by:



| |  |  | the cyclical nature of both the TFT-LCD industry, including fluctuations in average selling prices, and the markets served by our customers;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the speed at which we and our competitors expand production capacity;
| | - |  | ---------------------------------------------------------------------



| |  |  | access to raw materials and components, equipment, electricity, water and other required utilities on a timely and economical basis;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | technological changes;
| | - |  | ----------------------



| |  |  | the loss of a key customer or the postponement of orders from a key customer;
| | - |  | -----------------------------------------------------------------------------



| |  |  | changes in end users spending patterns;
| | - |  | ----------------------------------------



| |  |  | the rescheduling and cancellation of large orders;
| | - |  | --------------------------------------------------



| |  |  | our customers adjustments in their inventory; and
| | - |  | --------------------------------------------------



| |  |  | natural disasters, such as typhoons and earthquakes, and industrial accidents, such as fires and power failures, as well as geo-political instability as a result of terrorism or
political or military conflicts.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Due to the
factors noted above and other risks discussed in this section, many of which are beyond our control, you should not rely on quarter-to-quarter comparisons to predict our future performance. Unfavorable changes in any of the above factors may
seriously harm our business, financial condition and results of operations. In addition, our results of operations may be below the expectations of public market analysts and investors in some future periods, which may result in a decline in the
price of the ADSs or shares.



Our results of operations
may be adversely affected if we cannot introduce new products on a timely basis or if our new products do not gain market acceptance.



Early product development by itself does not guarantee the success of a new product. Success also depends on other factors such as product acceptance by
the market. For example, although TFT-LCD technology was initially introduced commercially in the early 1990s, this technology began to gain wide market acceptance only in the last few years, especially in the consumer electronics sector. New
products are developed in anticipation of future demand. Our delay in the development of commercially successful products with anticipated technological advancement may adversely affect our business. We cannot assure you that the launch of any new
products will be successful, or that we will be able to produce sufficient quantities of these products to meet market demand.



We plan to continue to expand our operations to meet the needs of high-growth applications in computer products, consumer electronics, LCD television and
other markets as demand increases. Because these products, such as mobile phones, portable game consoles, digital cameras and LCD television, are expected to be marketed to a diversified group of end-users with demands for different specifications,
functions and prices, we have

##### Table of Contents

developed different marketing strategies to promote our panels for these products. We cannot assure you that our strategy to expand our market share for
these panels will be successful. If we fail to successfully market panels for these products, our results of operations will be adversely affected.



Our net sales and results of operations may suffer if there is a downturn in the demand for, or a further decrease in the average selling prices of,
panels for computer products.



A significant
percentage of our net sales is derived from customers who use our TFT-LCD panels in computer products such as notebook computers and desktop monitors. Net sales of panels for computer products represented 88.3%, 85.2% and 78.1% of our net sales in
2002, 2003 and 2004, respectively. Demand for our panels for computer products is affected by numerous factors, including the general demand of the end-use markets and price attractiveness. For example, demand for desktop monitors is affected by the
rate of substitution of TFT-LCD monitors for cathode ray tube, or CRT, monitors. We believe that a significant percentage of our net sales is, and will continue to be, derived from end users purchasing TFT-LCD monitors to replace their existing CRT
monitors. The rate of substitution of TFT-LCD monitors for CRT monitors may be affected by a general slowdown in the global economy or a change in the average selling prices of such products which may also adversely affect the demand. In addition,
since most brand companies sell their computer products bundled with TFT-LCD monitors, a change in the bundling policy of brand companies could also reduce the demand for our products. Demand for notebook computer displays may be affected by various
factors, including a slowdown in information technology spending by corporations as well as a decrease in consumer spending as a result of a general slowdown in the global economy. Demand for notebook computers is also affected by price changes. A
slowdown in the demand for notebook computers could adversely affect the number of panels sold and the average selling prices for our notebook computer panels.



If the demand for LCD television or consumer electronics products, or our market share in such end-use markets, does not grow as expected, our
business prospects and results of operations may suffer.



Although panels for use in LCD television and consumer electronics products accounted for a small percentage of our net sales in 2004, we believe that such end-use markets present opportunities for growth. As end users may find LCD
television attractive because of their thin size as compared to traditional CRT televisions, we believe that a substantial portion of our sales growth will be derived from end users purchasing LCD televisions as additional televisions or to replace
traditional CRT televisions. We have installed, and we expect to continue to install, production capacity in anticipation of increased demand for LCD television generated as a result of the growing market acceptance of LCD television. As a result,
if end users purchase LCD televisions at a slower rate than we expect, we may not be able to maintain high utilization rates of the capacity installed or allocated to manufacture panels for LCD television. In addition, we may face greater than
expected downward pricing pressures for our panels used for LCD television and other applications as a result of excess supply of such panels due to excess capacity or as a result of price competition by competitors seeking to stimulate demand in
order to maintain or increase market share. We also manufacture panels for use in consumer electronics products. Demand for consumer electronics products that use TFT-LCD panels may be adversely affected by numerous factors, including a slowdown in
general economic conditions and a change in price. If there is a slowdown in the demand for LCD television or consumer electronics products that use TFT-LCD panels, our business prospects and results of operations may suffer.



If we are unable to maintain high capacity utilization rates, our
profitability will be adversely affected.



High
capacity utilization rates allow us to allocate fixed costs over a greater number of panels produced. Increases or decreases in capacity utilization rates can significantly impact our gross margins. Accordingly, our ability to maintain or improve
our gross margins will continue to depend, in part, on maintaining high capacity utilization rates. In turn, our ability to maintain high capacity utilization will depend on the ramp-up progress of our advanced production facilities and our ability
to efficiently and effectively allocate production capacity among our product lines, as well as the demand for our products and our ability to offer products that meet our customers requirements at competitive prices. Although we maintained
high capacity utilization rates in 2003



8

##### Table of Contents

and 2004 and, in particular, have been successful to date in the ramp-up of our fifth-generation fabs, our results of operations in the past have been
negatively affected by low capacity utilization. We cannot assure you that we will be able to maintain high capacity utilization rates through 2005 or beyond. If demand for our products does not meet our expectations, our capacity utilization will
decrease and our gross margins will suffer.



We depend on
a small number of customers for a substantial portion of our net sales, and a loss of any one of these customers, or a significant decrease in orders from any of these customers, would result in the loss of a significant portion of our net sales.



We are dependent on a small number of customers for a
substantial portion of our business. In 2002, 2003 and 2004, our five largest customers accounted for 39.3%, 43.6% and 35.1%, respectively, of our net sales. In addition, certain customers individually accounted for more than 10% of our net sales in
each of the last three years. BenQ Corporation, or BenQ, and its subsidiaries accounted for 20.8%, 20.9% and 19.9% of our net sales in 2002, 2003 and 2004, respectively. As some of our major customers are brand companies which also provide original
equipment manufacturing services for other brand companies, such as BenQ, our panels shipped to these customers include both panels ordered for their own account as well as panels ordered by or on behalf of their brand company customers.



In recent years, our largest customers have varied due to changes in our
product mix. We expect that we will continue to depend on a relatively small number of customers for a significant portion of our net sales and may continue to experience fluctuations in the distribution of our sales among our largest customers as
we periodically adjust our product mix. Our ability to maintain close and satisfactory relationships with our customers is important to the ongoing success and profitability of our business. If any of our significant customers reduces, delays or
cancels its orders, our business could be seriously harmed. Similarly, a failure to manufacture sufficient quantities of panels to meet the demands of these customers may cause us to lose customers or market share and our business may suffer as a
result.



Our customers generally do not place purchase
orders far in advance, which makes it difficult for us to predict our future revenues and allocate capacity efficiently and in a timely manner.



Our customers generally provide rolling forecasts four to six months in advance of, and do not place firm purchase orders until one month before, the
expected shipment date. In addition, due to the cyclical nature of the TFT-LCD industry, our customers purchase orders have varied significantly from period to period. As a result, we do not typically operate with any significant backlog. The
lack of significant backlog makes it difficult for us to forecast our revenues in future periods. Moreover, we incur expenses and adjust inventory levels of raw materials and components based in part on customers forecast, and we may be unable
to allocate production capacity in a timely manner to compensate for shortfalls in sales. We expect that, in the future, our sales in any quarter will continue to be substantially dependent upon purchase orders received in that quarter. The
inability to adjust production costs, to obtain necessary raw materials and components or to allocate production capacity quickly to respond to the demand for our products may affect our ability to maximize results of operations, which may result in
a negative impact on the value of your investment in the ADSs or our shares.



Our future competitiveness and growth prospects could be adversely affected if we are unable to complete the construction and installation of our 7.5-generation fab as scheduled or encounter unforeseen
disruptions in manufacturing at our 7.5-generation fab.



In the third quarter of 2004, we commenced construction of our 7.5-generation fab that is designed to process substrates of 1,950 mm x 2,250 mm, which is the optimal size for the production of panels larger than 40-inches. Based on our
current schedule, we plan to begin installation of machinery and equipment in the second quarter of 2006 and begin commercial production in the fourth quarter of 2006. The successful completion of our 7.5-generation fab is dependent upon a number of
factors, including: timely delivery of equipment and machinery and the hiring and training of new skilled personnel. Although we believe that we have the internal capabilities and know-how to construct, install and operate a 7.5-generation fab, no
assurances can be

##### Table of Contents

given that we will be successful in establishing our 7.5-generation fab. We cannot assure you that we will be able to obtain from third parties, if
necessary, the technology, intellectual property or know-how that may be required for a 7.5-generation fab on acceptable terms. In addition, delays in the delivery of equipment and machinery as a result of increased demand for such equipment and
machinery or the delivery of equipment and machinery that do not meet our specifications could delay the establishment of our 7.5-generation fab. In addition, the manufacturing processes for TFT-LCD panels are highly complex and potentially
vulnerable to disruptions. In particular, the manufacturing processes for 7.5-generation fabs are currently untested. If we are unable to complete our 7.5-generation fab as scheduled, or face unforeseen disruptions in the manufacturing processes, we
may not be able to realize the potential gains from the manufacturing of 7.5-generation fabs and may face disruptions in capturing the growth opportunities associated with the expected expansion of the market for LCD TV panels.



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



Historically, we have been able to finance our capital expenditures through cash flow from our operating activities and financing activities, including the issuance of equity securities, long-term borrowings and the
issuance of convertible and other debt securities. Our ability to expand our production facilities and establish next generation fabs will continue to largely depend on our ability to obtain sufficient cash flow from operations as well as external
funding. We expect to make substantial capital expenditures in connection with the expansion of our production capacity, including investments in 2005 in connection with the ramp-up of our sixth-generation fab, the establishment of a third
fifth-generation fab, a 7.5-generation fab and our third in-house color filter production facility. These capital expenditures will be made well in advance of any additional sales to be generated from these expenditures. We may lose market share if
we do not have the capital resources to complete our expansion plans or if our actual expenditures exceed planned expenditures for any number of reasons, including changes in:



| |  |  | our growth plan;
| | - |  | ----------------



| |  |  | manufacturing process and product technologies;
| | - |  | -----------------------------------------------



| |  |  | market conditions;
| | - |  | ------------------



| |  |  | prices of equipment; and
| | - |  | ------------------------



| |  |  | interest rates and foreign exchange rates.
| | - |  | ------------------------------------------



We cannot assure you that required additional financing will be available to us on satisfactory terms, if at all. If adequate funds are not available on
satisfactory terms at appropriate times, we may have to curtail our expansion plans, which could result in a loss of customers, adversely affect our ability to implement successfully our business strategy and limit the growth of our business.



We operate in a highly competitive environment, and we
may not be able to sustain our current market position if we fail to compete successfully.



The markets for our products are highly competitive. We experience pressure on our prices and profit margins, due largely to additional and growing
industry capacity from competitors in Taiwan, Korea and Japan. The ability to manufacture on a large scale with greater cost efficiencies is a competitive advantage in our industry. Some of our competitors have greater access to capital and
substantially greater production, research and development, intellectual property, marketing and other resources than we do. Some of our competitors have announced their plans to develop, and have already invested substantial resources in, sixth- or
higher generation capacity. Our competitors may be able to introduce products manufactured using such capacity in advance of our schedule. In addition, some of our larger competitors have more extensive intellectual property portfolios than ours,
which they may use to their advantage when negotiating cross-licensing agreements for technologies. As a result, these companies may be able to compete more aggressively over a longer period of time than we can.

Our ability to compete successfully in the TFT-LCD industry also depends on factors beyond our control, including industry and general economic
conditions.



If brand companies do not continue to
outsource the manufacturing of their products to original equipment manufacturing service providers with production operations in Taiwan or the PRC, our sales and results of operations could be adversely affected.



In recent years, brand companies have increasingly outsourced the
manufacturing of their products to original equipment manufacturing service providers in Taiwan, or such providers with part or all of their production operations in the PRC. We believe that we have benefited from this outsourcing trend in large
part due to our production locations in both Taiwan and the PRC, which has allowed us to coordinate better our production and services with our customers requirements, especially in the areas of delivery time and product design support. We
cannot assure you that this outsourcing trend will continue. If brand companies do not continue to outsource the manufacturing of their products to original equipment manufacturing service providers with their production operations in Taiwan or the
PRC, our sales and results of operations could be adversely affected.



If we are unable to manage our growth effectively, our business could be negatively affected.



We have experienced, and expect to continue to experience, growth in the scope and complexity of our operations and in the number of our employees. For
example, we are currently devoting significant resources to the ramp-up of our sixth-generation fab, the establishment of a third fifth-generation fab, a 7.5-generation fab and our third in-house color filter production facility. This growth may
strain our existing managerial, financial and other resources. In order to manage our growth, we must continue to implement additional operating and financial controls and hire and train additional personnel for these functions. We cannot assure you
that we will be able to do so in the future, and our failure to do so could jeopardize our expansion plans and seriously harm our operations.



The loss of any key management personnel or the undue distraction of any such personnel may disrupt our business.



Our success depends largely upon the continued services of key senior
management, including our Chairman, President and Chief Executive Officer. We do not carry key person life insurance on any of our senior management personnel. If we lose the services of key senior management personnel, we may not be able to find
suitable replacements or integrate replacement personnel in a timely manner or at all, which would seriously harm our business. In addition, our continuing growth will, to a large extent, depend on the attention of key management personnel to our
daily affairs. For the foreseeable future, we expect that Mr. Kuen-Yao (K.Y.) Lees time will be divided between serving as Chairman and Chief Executive Officer of our company and Chairman and Chief Executive Officer of BenQ. If Mr. Kuen-Yao
(K.Y.) Lee is not able to devote enough time to our company, our operations may be negatively affected.

If we are not able to attract and retain skilled technical personnel, including research and
development and other personnel, our operations and expansion plans would be adversely affected.



Our success depends on our ability to attract and retain skilled employees, particularly engineering and technical personnel in the research and
development and manufacturing processing areas. In 2004, we established a new flat panel display research and development center, the AUO Technology Center, in Hsinchu Science Park. The 684,000 square foot, nine-storey research center houses eight
to 16 research labs, advanced training facilities and is expected to accommodate over 1,000 research engineers. We are also planning the establishment of a professional on-the-job training facility for employees, the AUO Learning Center. Without a
sufficient number of skilled employees, our operations and production quality would suffer. Competition for qualified technical personnel and operators in Taiwan is intense and the replacement of skilled employees is difficult. We may encounter this
problem in the future, as we require increased numbers of skilled employees for our expansion. If we are unable to attract and retain our technical personnel and other employees, this may adversely affect our business, and our operating efficiency
may deteriorate.



Potential conflicts of interest with
BenQ may cause us to lose opportunities to expand and improve our operations.



We face potential conflicts of interest with BenQ. BenQ is our largest shareholder, owning directly and indirectly 13.32% of our outstanding shares as of July 1, 2005, and is also one of our largest customers. BenQ
and its subsidiaries accounted for 20.8%, 20.9% and 19.9% of our net sales in 2002, 2003 and 2004, respectively. BenQs substantial interest in our company may lead to conflicts of interest affecting our sales decisions or allocations. In
addition, as of July 1, 2005, three of our nine directors and one of our three supervisors are representatives of BenQ, and Mr. Kuen-Yao (K.Y.) Lee, our Chairman and Chief Executive Officer, is also Chairman and Chief Executive Officer of BenQ. As a
result, conflicts of interest between their duties to BenQ and us may arise.



We cannot assure you that when conflicts of interest arise with respect to representatives of BenQ, the conflicts of interest will be resolved in our favor. These conflicts may result in lost corporate opportunities,
including opportunities that are never brought to our attention, or actions that may prevent us from taking advantage of opportunities to expand and improve our operations.



If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial
results or prevent fraud



The United States Securities
and Exchange Commission, or the SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules requiring every public company to include a management report on such companys internal controls over financial reporting in its
annual report, which contains managements assessment of the effectiveness of the companys internal controls over financial reporting. In addition, an independent registered public accounting firm must attest to and report on
managements assessment of the effectiveness of the companys internal controls over financial reporting. These requirements will first apply to our annual report on Form 20-F for the fiscal year ending December 31, 2006. Our management
may conclude that our internal controls over our financial reporting are not effective. Moreover, even if our management concludes that our internal controls over financial reporting are effective, our independent registered public accounting firm
may still be unable to attest to our managements assessment or may issue a report that concludes that our internal controls over financial reporting are not effective. Furthermore, during the course of the evaluation, documentation and
attestation, we may identify deficiencies that we may not be able to remedy in time to meet the deadline imposed by the Sarbanes-Oxley Act for compliance with the requirements of Section 404. If we fail to achieve and maintain the adequacy of our
internal controls, we may not be able to conclude that we have effective internal controls, on an ongoing basis, over financial reporting in accordance with the Sarbanes-Oxley Act. Moreover, effective internal controls are necessary for us to
produce reliable financial reports and are important to help prevent fraud. As a result, our failure to achieve and maintain effective internal



12

##### Table of Contents

controls over financial reporting could result in the loss of investor confidence in the reliability of our financial statements, which in turn could harm
our business and negatively impact the trading price of our ADSs. Furthermore, we anticipate that we will incur considerable costs and use significant management time and other resources in an effort to comply with Section 404 and other requirements
of the Sarbanes-Oxley Act.



Risks Relating to Manufacturing



Our manufacturing processes are highly complex, costly and
potentially vulnerable to disruptions that can significantly increase our production costs and delay product shipments to our customers.



Our manufacturing processes are highly complex, require advanced and costly equipment and are periodically modified to improve manufacturing yields and
production efficiency. We face the risk of production difficulties from time to time that could cause delivery delays and reduced production yields. These production difficulties include capacity constraints, construction delays, difficulties in
upgrading or expanding existing facilities, difficulties in changing our manufacturing technology and delays in the delivery or relocation of specialized equipment. We may encounter many of these difficulties in connection with the planned
establishment of our third fifth-generation fab and our 7.5-generation fab, and the ramp-up of production capacity for our sixth-generation fab. We may also encounter these difficulties in connection with the establishment of our third in-house
color filter production facilities as well as the adoption of new manufacturing process technologies. We cannot assure you that we will be able to complete our third fifth-generation fab, our 7.5-generation fab, our third in-house color filter
production facilities, and the ramp-up of our sixth-generation fab without material delays or difficulties, or that we will not encounter manufacturing difficulties in the future.



If we are unable to obtain raw materials and components in suitable quantity and quality from our suppliers, our
production schedules would be delayed and we may lose substantial customers.



Raw materials and component costs represent a substantial portion of our cost of goods sold. We must obtain sufficient quantities of high quality raw materials and components at acceptable prices and in a timely
manner. We source most of our raw materials and components, including critical materials like color filters, driver integrated circuits, cold cathode fluorescent lamps, or CCFL, and polarizer and glass substrates, from a limited group of suppliers,
both foreign and domestic. In 2001, we experienced a shortage of glass substrates due to the closure of the production facility of one of our two major suppliers of glass substrates. In addition, there was a shortage in the supply of color filters
and glass substrates beginning in the second half of 2003 which continued into 2004. In addition, based on announced plans for new TFT-LCD production capacity, there could also be a shortage in the supply of driver integrated circuits, polarizer and
CCFL. Our operations would be adversely affected if we could not obtain raw materials and components in sufficient quantity and quality at acceptable prices. We may also experience difficulties in sourcing adequate supplies for our operations if
there is a ramp-up of production capacity by TFT-LCD manufacturers, including our company, without a corresponding increase in the supply of raw materials and components. The impact of any material shortage in raw materials and components will be
magnified as we establish new fabs and continue to increase our production capacity.



Although approximately 37.4% of our raw materials and components was sourced locally in Taiwan in 2004, we depend on supplies of certain principal raw materials and components from suppliers in Japan. We cannot assure
you that we will be able to obtain sufficient quantities of raw materials and components and other supplies of an acceptable quality in the future. Our inability to obtain high-quality raw materials and components in a timely and cost-effective
manner may 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 our expansion plans.



We have purchased, and expect to purchase, a substantial portion of our
equipment from foreign suppliers, especially for our planned 7.5-generation fab. 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 satisfy only partially our equipment orders



13

##### Table of Contents

in the normal time frame. The unavailability of equipment, delays in the delivery of equipment or the delivery of equipment that does not meet our
specifications could delay implementation of our expansion plans and impair our ability to meet customer orders. If we are unable to implement our expansion plans on schedule or in line with customer expectations, our business may suffer.



If we are unable to manufacture successfully our
products within the acceptable range of quality, our results of operations will be adversely affected.



TFT-LCD manufacturing processes are complex and involve a number of precise steps. Defective production can result from a number of factors, including:



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



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



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



| |  |  | use of substandard raw materials and components; and
| | - |  | ----------------------------------------------------



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



From time to time, we have experienced, and may in the future 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 manufacturing processes. In addition, our production yield on new products will be lower than average as we develop the necessary expertise and experience to produce
those products. If we fail to maintain high production yields and high quality production standards, our reputation may suffer and our customers may cancel their orders or return our panels for rework, which will negatively affect our results of
operations.



If we violate environmental regulations, we
may be subject to fines or restrictions that could cause our operations to be delayed or interrupted and our business to suffer.



Our operations can expose us to the risk of environmental claims which could result in damages awarded or fines imposed against us. We must comply with
regulations relating to storage, handling, generation, treatment, emission, release, discharge and disposal of certain materials and wastes resulting from our manufacturing processes. We incurred small fines in December 2002 and October 2003 for
non-compliance with a waste storage-labeling requirement. In June 2004, we also incurred small fines for failure to update our air pollution emission permit.



Future changes to existing environmental regulations or unknown contamination of our sites, including contamination by prior owners and operators of our
sites, may give rise to additional compliance costs or potential exposure to liability for environmental claims that may seriously affect our business, financial condition and results of operations.



Risks Relating to Our Technologies and Intellectual Property



If we cannot successfully introduce, develop or acquire advanced
technologies, our profitability may suffer.



Technology and industry standards in the TFT-LCD industry evolve quickly, resulting in steep price declines in the advanced stages of a products life cycle. To remain competitive, we must continually develop or acquire advanced
manufacturing process technologies and build next generation fabs to lower production costs and enable timely release of new products. In addition, we expect to utilize other display technologies, such as organic light-emitting diode, or OLED, and
low temperature poly-silicon, or LTPS, technologies to develop new products. Our ability to manufacture products by utilizing more advanced manufacturing process technologies to increase production efficiency will be critical to our sustained
competitiveness. We plan to invest a substantial amount of capital to ramp-up our sixth-generation fab, establish a third fifth-generation fab and a 7.5-generation

##### Table of Contents

fab and have committed significant management resources to develop color filter production facilities. However, we cannot assure you that we will be
successful in completing the development of the sixth-generation fab or other future technologies for our fabs, or that we will be able to complete them without material delays or at the expected costs. If we fail to do so, our results of operations
and financial condition may be materially and adversely affected. We also cannot assure you that there will be no material delays in connection with our efforts to develop new technology and manufacture more technologically advanced products. If we
fail to develop or make advancements in product technologies or manufacturing process technologies on a timely basis, we may become less competitive.



Other flat panel display technologies or alternative display technologies could render our products uncompetitive.



We currently manufacture products primarily using TFT-LCD technology, which
is currently one of the most commonly used flat panel display technologies. We may face competition from flat panel display manufacturers utilizing alternative flat panel technologies, including plasma discharge panel, or PDP, and OLED technologies.
Currently, PDP technology is primarily used to produce panels larger than 30-inches for use in television, as compared to the TFT-LCD technology primarily used to produce panels less than 40-inches for use in monitors, notebooks and LCD television.
However, as the demand for LCD televisions with panel sizes as large as that of televisions using PDP technology continues to grow, competition between these two technologies is likely in the large-size television market. Another commercially
available flat panel technology is OLED. OLED technology is currently primarily used, and is beginning to compete with TFT-LCD technology, in small- to medium-size applications, such as mobile phones and digital still cameras. Future development of
OLED technology may also allow it to compete with TFT-LCD technology in larger applications such as monitors, notebooks and LCD television and render our products uncompetitive. In addition, there are other alternative flat panel technologies
currently in the research and development stage, such as field emission display, or FED, inorganic electroluminescent, or IEL, and surface-conduction electron-emitter, or SED, display technologies. If the various alternative flat panel technologies
currently commercially available or in the research and development stage are developed to have better price-to-performance ratios, such technologies may compete with TFT-LCD technology and render our products uncompetitive.



We also face competition from alternative display technologies, particularly
those utilizing projection technology, such as front digital mirror device projector, digital light processing projector, LCD projector and liquid crystal on silicon projector technologies. These alternative forms of display technology may be
competitive in terms of price to performance ratio. If alternative display technologies gain a larger market share in the market for large-size television, our business prospects may be adversely affected.



If we lose the support of our technology partners or the legal rights
to use our licensed manufacturing process or product technologies, our business may suffer.



Enhancing our manufacturing process and product technologies is critical to our ability to provide high quality products to our customers at competitive
prices. We intend to continue to advance our manufacturing process and product technologies through internal research and development and licensing from other companies. We currently have major licensing arrangements with Matsushita, Fujitsu Display
Technologies Corporation, or FDTC, Semiconductor Energy Laboratory Co., Ltd., or SEL, Toppan Printing Co., Ltd., or Toppan, and other companies for product and manufacturing process technologies used to produce a substantial number of our TFT-LCD
panels. These agreements are typically for terms of five to seven years. If we are unable to renew our technology licensing arrangements with some or all of these companies on mutually beneficial economic terms, we may lose the legal right to use
certain of the processes and designs which we may have employed to manufacture our products. Similarly, if we cannot license or otherwise acquire or develop new manufacturing process and product technologies that are critical to the development of
our business or products, we may lose important customers because we are unable to continue providing our customers with products based on advanced manufacturing process and product technologies.

##### Table of Contents

We have entered into patent and intellectual property license agreements that require periodic royalty
payments. In the future, we may need to obtain additional patent licenses or renew existing license agreements. We cannot assure you that these license agreements can be obtained or renewed on acceptable terms. If these license agreements are not
obtained or renewed on acceptable terms, our business and future results of operations may be materially and adversely affected.



Disputes over intellectual property rights could be costly and deprive us of the technology to stay competitive.



As technology is an integral part of our manufacturing process and product,
we have, in the past, received communications alleging that our products or processes infringe product or manufacturing process technology rights held by others, and expect to continue to receive such communications. We are currently involved in
intellectual property disputes with several companies. See Item 8. Financial InformationLitigation. There is no means of knowing all of the patent applications that have been filed in the United States or elsewhere and whether, if
the applications are granted, such patents would have a material adverse effect on our business. If any third party were to make valid intellectual property infringement claims against our customers or us, we may be required to:



| |  |  | discontinue using disputed manufacturing process technologies;
| | - |  | --------------------------------------------------------------



| |  |  | 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.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



If our products or manufacturing processes are found to infringe third-party
rights, we may be subject to significant liabilities and be required to change our manufacturing processes or products. This could restrict us from making, using, selling or exporting some of our products, which could in turn materially and
adversely affect our business and financial condition. In addition, any litigation, whether to enforce our patents or other intellectual property rights or to defend ourselves against claims that we have infringed the intellectual property rights of
others, could materially and adversely affect our results of operations because of the management attention required and legal costs incurred.



Our ability to compete will be harmed if we are unable to adequately protect our intellectual property.



We believe that the protection of our intellectual property rights is, and
will continue to be, important to the success of our business. We rely primarily on a combination of patent, trademark, trade secret and copyright law and contractual restrictions to protect our intellectual property. These afford only limited
protection. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to obtain, copy or use information that we regard as proprietary, such as product design and manufacturing process expertise. As of December 31,
2004, we had 536 U.S. patent applications pending, 663 Taiwan patent applications pending and 1,099 patents pending in other jurisdictions. Our pending patent applications and any future applications may not result in issued patents or may not be
sufficiently broad to protect our proprietary technologies. Moreover, policing any unauthorized use of our products is difficult and costly, and we cannot be certain that the measures we have implemented will prevent misappropriation or unauthorized
use of our technologies, particularly in foreign jurisdictions where the laws may not protect our proprietary rights as fully as the laws of the United States. Others may independently develop substantially equivalent intellectual property or
otherwise gain access to our trade secrets or intellectual property. Our failure to effectively protect our intellectual property could harm our business.

Political, Geographical and Economic Risks



Due to the location of our operations in Taiwan and the PRC, we and many of our customers and suppliers are vulnerable
to natural disasters and other events outside of our control, which may seriously disrupt our operations.



Most of our existing manufacturing operations, and the operations of many of our customers and suppliers, are located in Taiwan, which is vulnerable to
natural disasters. In 2004, approximately 40.6% of our net sales was derived from Taiwan-based customers. In addition, we have expanded our module assembly operations to the PRC since July 2002. Our module-assembly operations in the PRC, and the
operations of many of our customers and suppliers in that area, may also be vulnerable to natural disasters. As a result of this geographic concentration, disruption of operations at our fabs or the facilities of our customers and suppliers for any
reason, including work stoppages, power outages, water supply shortages, fire, typhoons, earthquakes or other natural disasters, could cause delays in production and shipments of our products. Any delays or disruptions could result in our customers
seeking to source TFT-LCD panels from other manufacturers. For instance, our operations stopped completely for five days in September 1999, largely because of a power outage caused by a severe earthquake. After the stoppage, it took us several days
to ramp-up to full operations. Shortages or suspension of power supplies have occasionally occurred, and have disrupted our operations. The occurrence of a power outage in the future could seriously hurt our business.



Our manufacturing processes require a substantial amount of water. Although
currently more than 75% of the water used in our production process is recycled, our production operations may be seriously disrupted by water shortages. For instance, the Hsinchu area, where one of our principal manufacturing sites is located,
experienced a drought in 2002. In response to the drought in 2002, the ROC authorities implemented water-rationing measures and began sourcing water from alternative sources, and therefore we did not encounter any water shortage. However, we may
encounter droughts in the Hsinchu, Taoyuan or Taichung areas in the future, where most of our current or future manufacturing sites are located. If another drought were to occur and we or the authorities were unable to source water from alternative
sources in sufficient quantity, we may be required to shut down temporarily or substantially reduce the operations of these fabs, which would seriously affect our operations. In addition, even if we were able to source water from alternative
sources, our reliance on supplemental water supplies would increase our operating costs. Furthermore, the disruption of operations at our customers facilities could lead to reduced demand for our products. The occurrence of any of these events
in the future could adversely affect our business.



We
have made investments in, and are exploring the possibility of expanding our businesses and operations to, or making additional investments in, the PRC, which may expose us to additional political, regulatory, economic and foreign investment risks.



We have expanded our module assembly operations to
the PRC. Depending on our business needs, we may further expand or adjust our business operations in the PRC in the future. Our businesses and operations and our future expansion or investment plans in the PRC are subject, to a significant degree,
to the political and economic condition, regulatory control and general legal developments in the PRC and other foreign investment risks. The PRC economy differs from the economies of most developed countries in many respects, including the
structure, level of government involvement, level of development, foreign exchange control and allocation of resources. The PRC economy has been transitioning from a planned economy to a more market-oriented economy. For the past two decades, the
PRC government has implemented economic reform measures emphasizing utilization of market forces in the development of the PRC economy. Although we believe these reforms will have a positive effect on our overall operations in the PRC, we cannot
predict whether changes in the PRCs political, economic and social conditions, laws, regulations and policies will have any adverse effect on our current or future operations in the PRC. For example, the PRC government has indicated publicly
that it may change its monetary policy to tighten the extension of credit and discourage investments, particularly in certain industries such as real estate and construction. This change in policy may adversely affect our operations in the PRC. In
addition, the interpretation of PRC laws and regulations involves uncertainties. We cannot assure you that changes in such laws and regulations, or in their interpretation and enforcement, will not have a material adverse effect on our businesses
and operations in the PRC.

##### Table of Contents

Although we have been advised that we have all the relevant government approvals required in
connection with our PRC operations, additional approvals from the PRC central government may be required.



We operate module assembly facilities in the Suzhou Industrial Park located in Suzhou, PRC, through our subsidiary, AU Optronics (Suzhou) Corp., Ltd. The
Suzhou Industrial Park is a special economic zone established by the PRC central government with others and is under the regulation of the Suzhou Industrial Park Administrative Committee, or SIPAC. Under PRC laws and regulations, foreign investment
projects require the approval of the relevant governmental authorities in the province or special economic zone in which the project is located and, in some circumstances, the approval of the relevant authorities of the PRC central government. In
connection with the initial establishment and subsequent capital increases of our PRC subsidiary, we received approvals from SIPAC, which were filed by SIPAC with the State Planning Commission, the National Development and Reform Commission and the
Ministry of Commerce of the central government of the PRC. We have been advised by SIPAC that such approvals and filings complete the approval process, which is consistent with the approval processes generally applicable to companies under the
regulation of SIPAC, and that all necessary PRC governmental approvals in connection with the initial establishment and subsequent capital increases of our PRC subsidiary have been obtained.



The interpretation of PRC laws and regulations involves uncertainties,
however, and there can be no assurance that all relevant authorities of the PRC central government will agree with SIPACs position, and it has come to our attention that additional approval from the PRC central government may be required for
the initial establishment and subsequent capital increases of our PRC subsidiary. If required, we intend to obtain any such additional approval in consultation with SIPAC. In that event, we cannot assure you as to when the PRC central government
will grant such approval, if at all. Because the PRC central government has significant discretion in dealing with our situation, we cannot assure you that the PRC central government will not take action that is material and adverse to our PRC
operations.



The current restrictions imposed by the ROC
government on investments in certain related businesses may limit our ability to compete with other TFT-LCD manufacturers that are permitted to establish TFT-LCD production operations in the PRC.



Many of our customers and competitors have expanded their businesses and
operations to the PRC. In order to take advantage of the lower production costs in China and to establish a presence in the China market, we established module-assembly facilities in Suzhou, Jiangsu Province of the PRC. We commenced operations at
such facilities in July 2002. Module-assembly involves connecting components to the cell panel. We may further explore the possibility of investing in other businesses or operations in the PRC as and when we are legally permitted to do so.
Currently, ROC laws and regulations permit investment in module-assembly operations in the PRC but do not permit investments in array and cell operations. We do not know when or if such ROC laws and regulations governing investment in the PRC will
be amended, and we cannot assure you that any such amendments to those regulations will permit us to invest in operations involving array and cell processes in the PRC.



Disruptions in Taiwans political environment could seriously harm our business and the market price of our
shares and ADSs.



Most of our assets and operations
are located in Taiwan and approximately 40% of our net sales is derived from customers in Taiwan. Accordingly, our business and financial condition may be affected by changes in local governmental policies and political and social instability.



Taiwan has a unique international political status. The
government of the PRC asserts sovereignty over mainland China and Taiwan, and does not recognize the legitimacy of the government of the ROC. The government of the PRC has indicated that it may use military force to gain control over Taiwan if
Taiwan declares independence or a foreign power interferes in Taiwans internal affairs. In particular, the increasing influence of the Democratic Progressive Party, which has in the past formally advocated Taiwans independence from the
PRC, including the reelection of Mr. Chen Shui-bian, a member of that party, as President of the ROC in March 2004, may increase political tensions and instability between the PRC and the ROC. In addition, on



18



---

##### Table of Contents

March 14, 2005, the National Peoples Congress of the PRC passed what is widely referred to as the anti-secession law, a law authorizing the
PRC military to respond to efforts by Taiwan to seek formal independence. An increase in tensions between the ROC and the PRC and the possibility of instability and uncertainty could adversely affect the prices of our ADSs and our shares. It is
unclear what effects any of the events described above may have on relations with the PRC. Relations between Taiwan and the PRC and other factors affecting Taiwans political environment could affect our business.



If economic conditions in Taiwan deteriorate, our current business and
future growth would be materially and adversely affected.



In recent years, the currencies of many East Asian countries, including Taiwan, have experienced considerable volatility and depreciation. The Central Bank of China, which is the central bank of the ROC, has from time to time intervened in
the foreign exchange market to minimize the fluctuation of the U.S. dollar/NT dollar exchange rate and to prevent significant decline in the value of the NT dollar. NT dollars have depreciated against U.S. dollars from US$1.00 = NT$27.52 on January
2, 1997 to US$1.00 = NT$31.64 on July 1, 2005, based on the noon buying rates published by the Federal Reserve Bank of New York.



Our business, financial condition and results of operations may be affected by changes in ROC government policies, taxation, inflation and interest rates
in Taiwan, as well as general economic conditions in Taiwan. In addition, the banking and financial sectors in Taiwan have been seriously harmed by the general economic downturn in Asia and Taiwan in recent years, which has caused a depressed
property market, and an increase in the number of companies filing for corporate reorganization and bankruptcy protection. As a result, financial institutions are more cautious in providing credit to businesses in Taiwan. We cannot assure you that
we will continue to have access to credit at commercially reasonable rates of interest or at all.



The market value of our ADSs may fluctuate due to the volatility of the ROC securities market.



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 smaller and more volatile than the securities markets in the United States. The Taiwan Stock Exchange has experienced substantial fluctuations in the prices and volumes of trading of
securities. In the past decade, the Taiwan Stock Exchange Index peaked at 12,495.34 in February 1990 and subsequently fell to a low of 2,560.47 in October 1990. On March 13, 2000, the Taiwan Stock Exchange Index experienced a 617-point drop, which
represented the single largest decrease in the Taiwan Stock Exchange Index in its history. The Taiwan Stock Exchange Index experienced a 17.1% increase in 2001, a 19.8% decrease in 2002 and a 32.3% increase in 2003. During the period from January 1,
2004 to December 31, 2004, the Taiwan Stock Exchange Index peaked at 7,034.10 on March 4, 2004, and reached a low of 5,325.68 on July 20, 2004. Over the same period, daily closing values of our shares ranged from NT$33.2 per share to NT$78.5 per
share. On July 1, 2005, the Taiwan Stock Exchange Index closed at 6,272.14, and the closing value of our shares was NT$54.5 per share.



The Taiwan Stock Exchange is particularly volatile during times of political instability, including when relations between Taiwan and the PRC are
strained. Several investment funds affiliated with the ROC government have also from time to time purchased securities from the Taiwan Stock Exchange to support the trading level of the Taiwan Stock Exchange. Moreover, the Taiwan Stock Exchange has
experienced problems, including market manipulation, insider trading and settlement defaults. The recurrence of these or similar problems could have an adverse effect on the market price and liquidity of our shares and ADSs.



If the NT dollar or other currencies in which our sales, raw materials
and components and capital expenditures are denominated fluctuate significantly against the U.S. dollar or the Japanese yen, our profitability may be seriously affected.



We have significant foreign currency exposure, and are affected by fluctuations in exchange rates among the U.S. dollar, the
Japanese yen, the NT dollar and other currencies. Our sales, raw materials and components and capital expenditures are denominated in U.S. dollars, Japanese yen and NT dollars in varying amounts. For example, in 2004, approximately 96.8% of our net
sales was denominated in U.S. dollars. During the same



19



---

##### Table of Contents

period, approximately 29.4%, 30.3% and 40.1% of our cost of goods sold (principally raw materials and component costs) was denominated in NT dollars,
Japanese yen and U.S. dollars, respectively. In addition, in 2004, approximately 30.9%, 53.1% and 13.4% of our total capital expenditures (principally for the purchase of equipment) was denominated in NT dollars, Japanese yen and U.S. dollars,
respectively. From time to time, we enter into forward foreign currency contracts to hedge our foreign currency exposure, but we cannot assure you that we will fully minimize the risk against exchange rate fluctuations and the impact on our results
of operations.



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



A substantial portion of our net sales is derived from sales to customers located outside of Taiwan. In 2002, 2003 and 2004, sales to our overseas customers accounted for 47.3%, 57.5% and 59.4%, respectively, of our net sales. In addition,
the majority of our sales to customers in Taiwan is made to original equipment manufacturing service provider customers that use our display panels in the products that they manufacture on a contract basis for brand companies worldwide. We expect
sales to customers outside of Taiwan to continue to represent a significant portion of our net sales. As a result, our business will continue to be vulnerable to disruptions in the international trading environment, including those caused by adverse
changes in foreign government regulations, political unrest, international economic downturns, terrorist attacks and continued military involvement in Iraq and Afghanistan. These disruptions in the international trading environment may affect the
demand for our products and change the terms upon which we sell our products overseas, which could seriously decrease our international sales.



A reoccurrence of Severe Acute Respiratory Syndrome, or SARS, or an outbreak of avian flu or other contagious diseases, may have an adverse effect
on the economies and financial markets of certain Asian countries and may adversely affect our results of operations.



In the first half of 2003, China, Hong Kong, Taiwan, Singapore, Vietnam and certain other countries experienced an outbreak of SARS, a highly contagious
form of atypical pneumonia. To date, the SARS outbreak that occurred in the first half of 2003 has had no significant impact on our production operations and those of our suppliers or customers. Additionally, the World Health Organization has warned
that a potentially lethal strain of the avian flu could spread from Southeast Asia to other areas, including Taiwan and other countries where our operations are located. We cannot assure you that future outbreaks of SARS, avian flu or other
contagious diseases will not occur and that any future outbreaks, or the measures taken by the ROC, PRC or other countries governments against such potential outbreaks, will not seriously interrupt our production operations or those of our
suppliers and customers. The perception that an outbreak of SARS, avian flu or other contagious disease may have an adverse effect on the economic conditions of certain countries in Asia.



Risks Related to our ADSs and our Trading Market



The market value of our ADSs may fluctuate due to the volatility of the securities markets.



The securities markets in the United States and other countries have
experienced significant price and volume fluctuations. Volatility in the price of our ADSs may be caused by factors beyond our control and may be unrelated to, or disproportionate to changes in, our results of operations. In the past, following
periods of volatility in the market price of a public companys securities, securities class action litigation has often been instituted against that company. Litigation of this kind could result in substantial costs and a diversion of our
managements attention and resources.



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



The ability to deposit shares into our ADS facility is restricted by ROC law. A significant number of withdrawals of shares underlying our ADSs would
reduce the liquidity of our ADSs by reducing the number of



20



---

##### Table of Contents

ADSs outstanding. As a result, the prevailing market price of our ADSs may differ from the prevailing market price of our shares on the Taiwan Stock
Exchange. Under current ROC law, no person or entity, including you and us, may deposit its shares in our ADS facility without specific approval of the ROC Financial and Supervisory Commission, unless:



(1) we pay stock dividends on our shares;



(2) we make a free distribution of shares;



(3) ADS holders exercise preemptive rights in the event of
capital increases for cash; or



(4) investors
purchase our shares, directly or through the depositary, on the Taiwan Stock Exchange, and deliver our shares to the custodian for deposit into our ADS facility, or our existing shareholders deliver our shares to the custodian for deposit into our
ADS facility.



With respect to (4) above, the depositary may
issue ADSs against the deposit of those shares only if the total number of ADSs outstanding following the deposit will not exceed the number of ADSs previously approved by the ROC Financial and Supervisory Commission, plus any ADSs issued pursuant
to the events described in the subparagraph (1), (2) and (3) above. Issuance of additional ADSs under item (4) above will be permitted to the extent that previously ADSs have been cancelled.



In addition, in the case of a deposit of our shares requested under item (4)
above, the depositary will refuse to accept deposit of our shares if such deposit is not permitted under any legal, regulatory or other restrictions notified by us to the depositary from time to time, which restrictions may specify blackout periods
during which deposits may not be made, minimum and maximum amounts and frequencies of deposits.



ADS holders will not have the same voting rights as our shareholders, which may affect the value of the ADSs.



ADS holders voting rights as to the shares represented by such
holders ADSs are governed by the deposit agreement. ADS holders will not be able to exercise voting rights on an individual basis. If holders representing at least 51% of our ADSs outstanding at the relevant record date instruct the depositary
to vote in the same manner regarding a resolution, including the election of directors and supervisors, the depositary will cause all shares represented by the ADSs to be voted in that manner. If, at the relevant record date, the depositary does not
receive instructions representing at least 51% of ADSs outstanding to vote in the same manner for any resolution, including the election of directors and supervisors, ADS holders will be deemed to have instructed the depositary or its nominee to
authorize all the shares represented by the ADS holders ADSs to be voted at the discretion of our Chairman or his designee, which may not be in the ADS holders interest.



ADS holders rights to participate in our rights offerings are limited, which could cause dilution to the
holdings of ADS holders.



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 ADS holders those rights unless both the distribution of the rights and the underlying securities to all
our ADS holders are either registered under the Securities Act or exempt from registration under the Securities Act. Although we may be eligible to take advantage of certain exemptions under the Securities Act available to certain foreign issuers
for rights offerings, we can give no assurances that we will be able to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement for any of these rights. Accordingly, ADS
holders may be unable to participate in our rights offerings and may experience dilution with respect to their holdings.



Our issuance of stock bonuses to employees may have a dilutive effect on our ADSs.



Similar to other technology companies in Taiwan, from time to time we may
issue bonuses to our employees in the form of shares, valued at par, under the ROC Company Law and our articles of incorporation. Since these shares are issued at par value, the issuance of these shares may have a dilutive effect on ADSs.



21

##### Table of Contents

Non-ROC holders of ADSs who withdraw our shares will be required to obtain a foreign investor
investment identification and appoint a local custodian and agent and a tax guarantor in the ROC.



Under current ROC law, if you are a non-ROC person and wish to withdraw and hold our shares from a depositary receipt facility, you will be required to
obtain a foreign investor investment identification, or the Foreign Investor Investment I.D., issued in accordance with the ROC Regulations Governing Securities Investment by Overseas Chinese and Foreign Nationals, or the Investment Regulations. You
will also be required to appoint an eligible agent in the ROC to open a securities trading account and a Taiwan Securities Central Depository Co., Ltd. book-entry account and a bank account, to pay ROC taxes, remit funds, exercise shareholders
rights and perform such other functions as you may designate upon such withdrawal. In addition, you will be required to appoint a custodian bank to hold the securities in safekeeping, make confirmation and settle trades and report all relevant
information. Without obtaining such Foreign Investor Investment I.D. under the Investment Regulations and opening such accounts, the non-ROC withdrawing holder would be unable to hold or subsequently sell our shares withdrawn from the depositary
receipt facility on the Taiwan Stock Exchange or otherwise. There can be no assurance that such withdrawing holder will be able to obtain the Foreign Investor Investment I.D. and open such accounts in a timely manner.



Non-ROC holders of ADSs withdrawing our shares represented by ADSs are also
required under current ROC law and regulations to appoint an agent in the ROC for filing tax returns and making tax payments. Such agent must meet certain qualifications set by the ROC Ministry of Finance and, upon appointment, becomes a guarantor
of such withdrawing holders ROC tax obligations. Generally, evidence of the appointment of such agent and the approval of such appointment by the ROC tax authorities may be required as conditions to such withdrawing holders repatriation
of the profits. There can be no assurance that such withdrawing holder will be able to appoint and obtain approval for such agent in a timely manner.



The protection of the interests of our public shareholders available under our articles of incorporation and the laws governing ROC corporations is
different from that which applies to a U.S. corporation.



Our corporate affairs are governed by our articles of incorporation and by the laws governing ROC corporations. The rights and responsibilities of our shareholders and members of our board of directors under ROC law are different from those
that apply to a U.S. corporation. Directors of ROC corporations are required to conduct business faithfully and act with the care of good administrators. However, the duty of care required of an ROC corporations directors may not be the same
as the fiduciary duty of a director of a U.S. corporation. In addition, controlling shareholders of U.S. corporations owe fiduciary duties to minority shareholders, while controlling shareholders in ROC corporations do not. The ROC Company Law also
requires that a shareholder continuously hold at least 3% of our issued and outstanding shares for at least a year in order to request that a supervisor institute an action against a director on the companys behalf. Therefore, our public
shareholders may have more difficulty protecting their interests against actions of our management, members of our board of directors or controlling shareholders than they would as shareholders of a U.S. corporation.



Future sales or perceived sales of securities by us, our executive
officers, directors, supervisors or major shareholders may hurt the price of our ADSs.



The market price of our ADSs could decline as a result of sales of ADSs or shares or the perception that these sales could occur. As of July 1, 2005, we
had an aggregate of 4,958,040,897 shares issued and outstanding which were freely tradable, except for 12,000,000 shares of our treasury shares. If we, our executive officers, directors, supervisors or our shareholders, sell ADSs or shares, the
market price for our shares or ADSs could decline. Future sales, or the perception of future sales, of ADSs or shares by us, our executive officers, directors, supervisors or existing shareholders could cause the market price of our ADSs to decline.



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



We are a company limited by shares
and incorporated under the ROC Company Law. All of our directors, supervisors and executive officers, and some of the experts named herein, are residents of Taiwan. As a result, it



22

##### Table of Contents

may be difficult for holders of our shares or ADSs to enforce against us or them judgments obtained outside the ROC, including those predicated upon the
civil liability provisions of the federal securities laws of the United States. There is doubt as to the enforceability in the ROC, either in original actions or in actions for enforcement of judgments of United States courts, of civil liabilities
predicated on the United States federal securities laws.

4.B. Business Overview



Introduction



We design, develop, manufacture, assemble and market flat
panel displays and substantially all of our products are TFT-LCD panels. TFT-LCD is currently the most widely used flat panel display technology. Our panels are used in computer products, such as notebook computers and desktop monitors, consumer
electronics products, such as digital cameras, digital camcorder, car television, car navigation systems and portable DVD players, as well as for LCD television.



We sell our panels primarily to companies that design and assemble products based on their customers specifications,
commonly known as original equipment manufacturing service providers. These original equipment manufacturing service providers, most of whose production operations are located in Taiwan and the PRC, use our panels in the products that they
manufacture on a contract basis for brand companies worldwide. Our operations in Taiwan and the PRC allow us to better coordinate our production and services with our customers requirements, especially in the areas of delivery time and design
support. Some of our major original equipment manufacturing service provider customers include BenQ, Lite-On Technology and Top Victory Electronics. BenQ is a shareholder of our company, and held directly and indirectly 13.32% of our outstanding
shares as of July 1, 2005. We also sell our products to some brand companies on a direct shipment basis.



We currently manufacture TFT-LCD at production facilities commonly known as fabs. We were one of the first TFT-LCD manufacturers in Taiwan to
commence commercial production at a fifth-generation fab and we now operate two fifth-generation fabs. We believe we were the first TFT-LCD manufacturer in Taiwan to commence production at a sixth-generation fab. New generations of TFT-LCD fabs are
equipped to process increasingly larger sheets of glass, or substrates. For example, our sixth-generation fab is capable of processing substrates with dimensions of up to 1,500 x 1,850 millimeters, our fifth-generation fabs are capable of processing
substrates with dimensions of up to 1,100 x 1,250 millimeters and 1,100 x 1,300 millimeters, respectively, and our fourth-generation fab is capable of processing substrates with dimensions of up to 680 x 880 millimeters.

##### Table of Contents

We commenced commercial production of small- to medium-size panels in 1994 and large-size panels in 1999.
We have significantly expanded our capacity since 1999. With production facilities utilizing 3.5-, fourth-, fifth- and sixth-generation technologies, we have the flexibility to produce a large number of panels of various sizes. We operate two
fifth-generation fabs that commenced commercial production in March 2003 and February 2004, respectively and we are in the process of establishing a third fifth-generation fab which we expect to commence commercial production in the fourth quarter
of 2005. Our sixth-generation fab commenced commercial production in March 2005. Our existing operations are located at three principal manufacturing sites in Taiwan and one module-assembly site in Suzhou, PRC.



Principal Products



We manufacture a wide range of TFT-LCD panels for the following principal product categories:



| |  |  | Computer products, which typically utilize display panels ranging from 8.4 inches to larger than 20 inches, primarily for use in notebook computers and desktop monitors.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Consumer electronics products, which typically utilize display panels ranging from 1.5 inches to 10.2 inches or above for use in products such as digital cameras, digital
camcorders, mobile phones, car television monitors, car navigation systems, portable television, multiple function machines, printer displays, portable game consoles and portable DVD players.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

fourth quarter of 2002.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We design, develop and
manufacture our panels to address specific needs of the end-products in which they are used, such as thinness, light weight, resolution, color quality, brightness, low power consumption, touch panel features, fast response time and wide viewing
angles. For example, it is important for notebook computer displays to be lightweight and thin, and to have low power consumption, while desktop monitors require high brightness and wider viewing angles.



The following table sets forth our production volume by product category for
the periods indicated:

Computer Products



Panels for Notebook Computers. In 2002, 2003 and 2004 sales of panels
for notebook computers accounted for 29.6%, 21.0% and 19.2%, respectively, of our net sales. The decline in notebook computer panels sales as a percentage of our total net sales resulted primarily from the increase in sales of our other products,
which grew at a faster rate than sales of notebook computer panels.



The most commonly produced sizes for panels for notebook computers have changed in recent years, partly as a result of migration in TFT-LCD production technology. The most commonly produced panel sizes for notebook computers were from 12.1
inches to 14.1 inches in 2000 and 2001 and 14.1 and 15.4 inches in 2002, 2003 and 2004. As fifth-generation production capacity increases, we expect that 15.4-inch panels will continue to be one of the most commonly produced sizes for notebook
computers, with demand for 17-inch panels increasing as well. We typically seek to increase our production of notebook panels of a certain size, one to two quarters ahead of expected product migration towards that panel size.



In 2004, unit sales of our panels for notebook computers were approximately
4.9 million, of which a substantial majority was accounted for by 14.1 inch to 15.4 inch panels. In 2004, our net sales accounted for by panels for notebook computers was approximately NT$32.3 billion.



Panels for Desktop Monitors. We commenced commercial production of
desktop monitor panels in the first quarter of 2000. In 2002, 2003 and 2004 sales of panels for desktop monitors accounted for 58.7%, 64.2% and 58.9%, respectively, of our net sales. We expect that our sales of desktop monitor panels will continue
to grow in 2005, primarily as a result of our capacity expansion and demand growth due to the continued trend toward the bundling of TFT-LCD monitors with new computers and the substitution effect of purchasers replacing CRT monitors with TFT-LCD
monitors.



The most commonly produced size of desktop monitors
changes as the generation of TFT-LCD manufacturing technology evolves, with manufacturers moving production to panel sizes that make the most efficient use of glass substrates processed by their fabs. 17-inch panels were most commonly produced for
desktop monitors in 2004. In 2004, unit sales of our panels for desktop monitors was approximately 12.2 million, of which a significant portion was accounted for by 17- and 19-inch panels. In 2004, our net sales accounted for by panels for desktop
monitors was approximately NT$99.0 billion, of which a significant majority was accounted for by 17- and 19-inch panels. We expect 17-inch panels will continue to be one of the most commonly produced desktop monitor sizes, with increasing demand for
19-inch panels in 2005.

Consumer Electronics Products



Our panels for consumer electronics products, including digital cameras,
camcorders, car television, car navigation systems, portable DVD players, multiple function machines, printer displays, portable game consoles and portable televisions, consist of display panels ranging from 1.5 to 10.2 inches or above. Our sales of
panels for consumer electronics products as a percentage of our total net sales has varied from 8.9% in 2002 to 11.4% in 2003 to 12.5% in 2004. The markets for our panels for consumer electronics products are typically more stable and less cyclical
than the markets for our computer products because of the high level of our involvement in the design process of our customers and the customized nature of consumer electronics panels. Unit sales of our panels for consumer electronics products
increased 57.1% to 33,697.7 thousand panels in 2004 from 21,454.3 thousand panels in 2003 primarily as a result of the growing market acceptance of the use of TFT-LCD panels in consumer electronics products and increase demand for products such as
portable DVD players and other handheld devices.



LCD
Television



Our panels for LCD television consist of
panels with a panel size of 14 inches or above. We commenced commercial production of panels for LCD television in the fourth quarter of 2002. Our current portfolio of LCD television panels consists of 14- to 46-inch panels. Our sales of LCD
television panels, as a percentage of our net sales, increased from 2.7% in 2003 to 8.7% in 2004. In 2004, the most commonly produced size of LCD television panels were those below 20-inches. We believe that our sales of LCD television panels will
continue to grow in 2005, primarily as a result of the commencement of production at our sixth-generation fab and expected demand growth for LCD television, while we expect average selling prices of panels for LCD television to continue to decline.
We also believe that beginning in 2005 there has been a trend towards greater customer demand for larger LCD television panels (above 30-inches). Units sales of our LCD television panels increased to 1,369.4 thousand panels in 2004 from 249.9 panels
in 2003 primarily as a result of growing market demand and the replacement of CRT televisions with LCD televisions by consumers.



Customers, Sales and Marketing



We sell our panels primarily to original equipment manufacturing service providers such as BenQ, Lite-On Technology and Top Victory Electronics. BenQ is a
shareholder of our company, and held directly and indirectly 13.32% of our outstanding shares as of July 1, 2005. We also own a 5.47% equity interest in BenQ as of December 31, 2004. These original equipment manufacturing service providers, most of
whose production operations are located in Taiwan and the PRC, use our panels in the products they manufacture on a contract basis for brand companies. We also sell our panels to some brand companies on a direct shipment basis.

##### Table of Contents

Our sales in Taiwan, as set forth in the table above, represent a significant portion of our net sales
for the past three years. The majority of these sales were made to original equipment manufacturing service providers who use our panels in the products they manufacture on a contract basis for brand companies worldwide. As many of these service
providers relocate an increasing portion of their production capacity from Taiwan elsewhere, or expand their operations elsewhere, typically to the PRC, due to cost and other considerations, orders placed in Taiwan by such customers have accounted
for a decreasing portion of our net sales in recent years.



We
sell our panels for notebook computers primarily to original equipment manufacturing service providers with production operations in Taiwan and the PRC that design and manufacture notebook computers based on the specifications of their brand company
customers. Our original equipment manufacturing service provider customers include Compal, Quanta Computer and Wistron Infocomm. We market our panels to, and negotiate prices with, both our original equipment manufacturing service provider customers
and their brand customers, as display panels often constitute a significant part of the end product.



We sell our panels for desktop monitors through sales channels similar to those for notebook computers. We supply desktop monitor panels primarily to
original equipment manufacturing service providers such as BenQ, Lite-On Technology and Top Victory Electronics.



We sell most of our panels for digital still cameras and camcorders to brand companies based in Japan. We sell our panels for car televisions primarily to
component manufacturers for automotive audio and video products based in the United States. We sell our panels for portable DVD players primarily to original equipment manufacturing service providers and component manufacturers, most of which are
located in Taiwan, the PRC and other Asian countries.



A
significant portion of our net sales is attributable to a small number of our customers. In 2002, 2003 and 2004, our five largest customers accounted for 39.3%, 43.6% and 35.1%, respectively, of our net sales. In addition, some customers
individually accounted for more than 10% of our net sales for each of the last three years. BenQ and its subsidiaries accounted for 20.8%, 20.9% and 19.9% of our net sales in 2002, 2003 and 2004, respectively. Since BenQ also provides original
equipment manufacturing services for its brand company customers, panels shipped to BenQ include both panels ordered for its own account as well as panels ordered by or on behalf of its brand company customers.



We focus our sales activities on a number of large customers with whom we
seek to build close relationships. We appoint a sales manager to serve as the main contact person with each of our major customers. Each product category has its own sales and marketing division, and is further subdivided into smaller teams
dedicated to each of our major customers. Each dedicated customer team is headed by an account manager who is primarily responsible for our relationship with that specific customer.



Our customers typically provide monthly non-binding rolling forecasts of their requirements for the coming four months, and
typically place purchase orders one month before the expected shipment date. We generally provide a limited warranty to our customers, including the provision of replacement parts and after-sale service for our products. In connection with these
warranty policies, based on our historical experience, we typically set aside an amount as a reserve to cover these warranty obligations. As of December 31, 2004, our reserve for warranties totaled NT$297.1 million (US$9.4 million). In addition, we
are required under several of our sales contracts to provide replacement parts for our products, at agreed prices, for a specified period of time.



We price our products in accordance with prevailing market conditions, giving consideration to the complexity of the product, the order size, the strength
and history of our relationship with the customer and our capacity utilization. Purchase prices and payment terms for sales to related parties are not significantly different from those for other suppliers. Our credit policy for sales to related
parties and other customers typically requires payment within 30 to 45 days. The average number of collection days extended for sales to our customers for the years ended December 31, 2002, 2003 and 2004, was 46 days, 47 days and 29 days,
respectively. We have not experienced any material problems relating to customer payments.

The TFT-LCD Manufacturing Process



The basic structure of a TFT-LCD panel may be thought of as two glass substrates sandwiching a layer of liquid crystal. The
front glass substrate is fitted with a color filter, while the back glass substrate has transistors fabricated on it. A light source called a backlight unit is located at the back of the panel.



The manufacturing process consists of hundreds of steps, but may be divided
into three primary steps. The first step is the array process, which involves fabricating transistors on the back substrate using film deposition, lithography and etching. The array process is similar to the semiconductor manufacturing process,
except that transistors are fabricated on a glass substrate instead of a silicon wafer. The second step is the cell process, which joins the back array substrate and the front color filter substrate. The space between the two substrates is filled
with liquid crystal. The third step is the module-assembly process, which involves connecting additional components, such as driver integrated circuits and backlight units, to the TFT-LCD panel. We established a color filter production facility at
one of our fifth-generation fabs with technical assistance from Toppan, one of our color filter suppliers, in order to meet a portion of our color filter requirements. We commenced commercial production of color filters at this facility in October
2003. We also established a color filter production facility at our sixth-generation fab in March 2005.



The array and cell processes are capital-intensive and require highly automated production equipment. TFT-LCD manufacturers typically design their own
fabs and purchase production equipment from various suppliers, most of which are based in Japan. Each TFT-LCD manufacturer combines various equipment according to its manufacturing process technologies to form a TFT-LCD fab. In addition to
developing our own manufacturing process technologies, we also license such technologies from other companies, such as Matsushita and FDTC. We have automated our array and cell processes, with the exception of some steps in the cell process, such as
panel inspection, panel baking and injection of liquid crystal. In contrast to the array and cell processes, the module-assembly process is highly labor-intensive, as it involves manual labor to assemble the pieces. We started to move a substantial
portion of our module-assembly process to Suzhou, PRC in July 2002, as part of our efforts to reduce labor costs and the majority of the module-assembly work is conducted in Suzhou.



Raw Materials and Components and Suppliers



Our manufacturing operations require adequate supplies of high-quality raw materials and components on a timely basis. We purchase our raw materials
and components based on forecasts from our customers, as well as our own assessments of our customers needs. We generally prepare forecasts one to four months in advance, depending on the raw materials and components, and update this forecast
monthly. We source most of our raw materials and components, including critical materials such as glass substrates, color filters, CCFL, polarizer and driver integrated circuits, from a limited group of suppliers. In order to reduce our raw
materials and component costs and our dependence on any one supplier, we generally purchase our raw materials and components from multiple sources. We typically do not enter into contracts with our suppliers. However, during periods of supply
shortages, we typically enter into supply contracts with suppliers to ensure a stable supply of necessary raw materials and components.



In 2001, we experienced a shortage of glass substrates due to the closure of the production facility of one of our two major suppliers of glass
substrates. There was a shortage in the supply of color filters and glass substrates beginning in the second half of 2003 which continued into 2004. In addition, based on announced plans for new TFT-LCD production capacity, there could also be a
shortage in the supply of driver integrated circuits. Our operations would be adversely affected if we could not obtain raw materials and components in sufficient quantity and quality. We may also experience difficulties in sourcing adequate
supplies for our operations if there is a ramp-up of production capacity by TFT-LCD manufacturers, including our company, without a corresponding increase in the supply of raw materials and components.



Raw materials and components constitute a substantial portion of our cost of
goods sold. An increase in the cost of our raw materials may adversely effect our gross margins.

We use a large amount of water and electricity in our manufacturing process.
We obtain water from government-owned entities and recycle more than 70% of the water that we use in production. We use electricity supplied by Taiwan Power Corporation. We maintain back-up generators that provide electricity in case of power
interruptions, which we have experienced from time to time. In September 1999, a power outage caused by a large earthquake resulted in a suspension of production at our fabs for five days. Except for this power outage, power interruptions in general
have not materially affected our production processes.



Equipment and
Suppliers



We depend on a number of equipment
manufacturers that make and sell the equipment that we use in our manufacturing processes. Our manufacturing processes depend on the quality and technological capacity of our equipment. We purchase equipment that is tailored to our specific
requirements for our manufacturing processes. The principal types of equipment we use to manufacture TFT-LCD panels include chemical vapor deposition equipment, steppers, developers and coaters.



We made significant purchases of equipment in 2004, and we expect to make
significant purchases in 2005, to implement our capacity expansion and technology advancement plans. See Item 5. Operating and Financial Review and ProspectsLiquidity and Capital Resources. We purchase equipment from a small number
of qualified vendors to assure consistent quality and performance. We typically order equipment four to six months or longer in advance of our planned installation.



Competition



The TFT-LCD industry is highly competitive. Most of our competitors operate fabs in Korea, Taiwan, Japan and the PRC. We believe there are no TFT-LCD fabs
in the United States or Europe. Our principal competitors are:



| |  |  | LG.Philips LCD and Samsung Electronics, in Korea;
| | - |  | -------------------------------------------------



| |  |  | Chi Mei Optoelectronics, Chunghwa Picture Tubes, Hannstar Display, Quanta Display, Innolux Display and Toppoly Optoelectronics, in Taiwan;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Hitachi, Tottori Sanyo, Sharp and Toshiba Matsushita Display Technology, in Japan; and
| | - |  | --------------------------------------------------------------------------------------



| |  |  | SVA-NEC and BOE-OT, in the PRC.
| | - |  | -------------------------------



The principal elements of competition for customers in the TFT-LCD market include:



| |  |  | price, based in large part on the ability to ramp-up lower cost, next generation production facilities before competitors;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | product features and quality;

Quality Control



We
have implemented quality inspection and testing procedures at all of our fabs and module-assembly facilities. Our quality control procedures include statistical process controls, which involves sampling measurements to monitor and control the
production processes. We perform outgoing quality control based on sampling plans, ongoing reliability tests covering a wide range of application conditions, in-process quality control to prevent potential quality deviations, and other programs
designed for process measurement and improvement, reduction of manufacturing costs, maintenance of on-time delivery, increasing in-process production yields and improving field reliability of our products. If a problem is detected, we take steps to
contain the problem, conduct defect analyses to identify the cause of the problem and take appropriate corrective and preventive actions.



We visually inspect and test all completed panels to ensure that production standards are met. To ensure the effective and consistent application of our
quality control procedures, we provide quality control training to all of our production line employees according to a certification system depending on the particular levels of skills and knowledge required.



We also perform quality control procedures for raw materials and components
used in our products. These procedures include testing samples for large batches, obtaining vendor testing reports and testing to ensure compatibility with other raw materials and components, as well as vendor qualification and vendor ratings.



Our quality control programs have received accredited
International Organization of Standards ISO 9001 certifications, as well as qualifications from our customers. In addition, most of our facilities have been certified as meeting the International Organization of Standards ISO-14001 environmental
protection standards, with certification for our recently completed fifth-generation fab pending. The International Organization of Standards certification process involves subjecting our manufacturing processes and quality management systems to
periodic reviews and observations. International Organization of Standards certification is required by certain European countries in connection with sales of industrial products in those countries. We believe that certification also provides
independent verification to our customers regarding the quality control employed in our manufacturing and assembly processes.



Intellectual Property



We currently hold a total of 950 patents, including 616 in Taiwan and 177 in the United States. These include patents for TFT-LCD manufacturing processes
and products. These patents will expire at various dates from 2007 through 2024. We also have a total of 663 pending patent applications in Taiwan, 536 in the United States and 1,099 in other jurisdictions, including the PRC, Japan and Korea as of
December 31, 2004. In addition, we have registered AU Optronics as a trademark and service mark in the ROC and PRC, and we are in the process of registering our logo as a trademark and service mark in the ROC and PRC.



We require all of our employees to sign an employment agreement which
prohibits the disclosure of any of our trade secrets, confidential information and proprietary technologies and we also require technical personnel to assign to us any inventions they develop that are related to our business.

We have licenses to use certain technology and processes from certain companies. In 2002, 2003 and 2004,
our running royalty expenses to the companies from which we license intellectual property were NT$229.4 million, NT$405.4 million and NT$1,017.8 million, respectively, which accounted for 0.3%, 0.4% and 0.6%, respectively of our net sales. We expect
that our royalty expenses relating to intellectual property licenses will increase in the future due to increases in unit sales as well as our license agreement with SEL entered into as a part of a settlement and mutual release agreement with SEL on
September 3, 2003.



We intend to continue to file patent
applications, where appropriate, to protect our proprietary technologies. We may find it necessary to enforce our patents or other intellectual property rights or defend ourselves against claimed infringement of the rights of others through
litigation, which could result in substantial cost and diversion of our resources. We may suffer legal liabilities and financial and reputational damages if we are found to infringe product or process technology rights held by others. We are
currently involved in litigation regarding alleged patent infringement. See Item 8Financial InformationLitigation.



Insurance



We maintain insurance policies on our production facilities, buildings, machinery and inventories covering property damage and damage due to fire,
earthquakes, floods, and other natural and accidental perils. Our property insurance covers replacement costs for our assets. As of December 31, 2004, our insurance also included protection from covered losses, including property damage up to
maximum coverage of NT$21.2 billion for all of our inventories and NT$228.8 billion for our equipment and facilities. In addition, as of December 31, 2004, we had insurance coverage for business interruptions in the aggregate amount of NT$5.3
billion. See Item 3. Key InformationRisk FactorsPolitical Geographical and Economic RisksDue to the location of our operations in Taiwan and the PRC, we and many of our customers and suppliers are vulnerable to natural
disasters and other events outside of our control, which may seriously disrupt our operations.



We also maintain insurance policies, including director and officer liability insurance, employee group health insurance, travel and life insurance,
employer liability insurance, general liability insurance, and policies that provide coverage for risks during the shipment of goods and equipment, as well as during equipment installation at our fabs.



Environmental Matters



Our manufacturing processes involve the use of hazardous materials and generate a significant amount of waste products,
including wastewater, liquid waste products and hazardous gases, which are strictly monitored by local environmental protection bureaus. To meet ROC environmental standards, we employ various types of pollution control equipment for the treatment of
hazardous gases, liquid waste, solid waste and the treatment of wastewater and chemicals in our fabs. We control exhaust gas and wastewater on-site. The treatment of solid and liquid wastes is subcontracted to third parties off-site in accordance
with pollution control requirements.



We incurred small fines
in December 2002 and October 2003 for non-compliance with a waste storage-labeling requirement. In June 2004, we also incurred small fines for failure to update our air pollution emission permit. Following each of the infractions described above, we
have taken the necessary steps to obtain the appropriate permit and believe that we are in compliance with the existing environmental laws and regulations in Taiwan.

Expansion Projects



Set forth below is a description of our principal expansion projects which we expect to finance with cash on hand, long-term
debt and cash flow from operations.



Fifth-Generation
Fabs. We commenced commercial production at our second fifth-generation fab which is capable of processing substrates with dimensions of 1,100 x 1,300 millimeters, in February 2004. As of December 31, 2004, our second fifth-generation fab had an
estimated input capacity of approximately 70,000 substrates per month. We plan to establish a third fifth-generation fab capable of processing substrates with dimensions of 1,100 x 1,300 millimeters which we expect to commence commercial production
in the fourth quarter of 2005. We also plan to establish a third color filter production facility in order to meet a portion of our color filter requirements at our two fifth-generation fabs as well as our other existing fabs. Our third
fifth-generation fab will be housed in the same facility as our 7.5-generation fab. We expect to spend approximately NT$10 billion to NT$11 billion to construct this facility and spend an additional NT$30 billion to NT$35 billion for the
installation of machinery and equipment at our third fifth-generation fab. As of December 31, 2004, we had spent a total of NT$5.0 billion for construction and the purchase of machinery and equipment at our third fifth-generation fab.



Sixth-Generation Fab. To meet the growth in the
large-size TFT-LCD market, we established a new fab in Taichung Science Park utilizing sixth-generation manufacturing technology. Our sixth-generation fab is capable of processing substrates with dimensions of 1,500 x 1,850 millimeters. Our
sixth-generation substrate size is designed to produce large-size panels with high efficiency and with capabilities of cutting, for example, eight 32-inch panels, six 37-inch panels or four 40-inch panels in wide format. Our sixth-generation fab
commenced commercial production in March 2005 and as of March 31, 2005 had an estimated input capacity of approximately 5,000 substrates per month. We expect that the estimated input capacity for our sixth-generation fab to increase to 60,000
substrates per month by the end of 2005. We also plan to establish color filter production and module-assembly facilities at our sixth-generation fab. As of December 31, 2004, we had incurred a total of NT$40.7 billion in connection with our new
sixth-generation fab, together with the new color filter production and module-assembly facilities within such fab. We expect to spend an additional amount of approximately NT$40.0 billion to NT$45.0 billion to complete our sixth-generation fab.



7.5-Generation Fab.We intend to establish a
7.5-generation fab in order to target the HDTV market and produce LCD TVs that are larger than 40-inches. We expect that our 7.5-generation fab will be capable of processing substrates with dimensions of 1,950 x 2,250 millimeters. Our 7.5-generation
substrate size is designed to produce large-size panels with high efficiency and with capabilities of cutting, for example, eight 42-inch panels, six 47-inch panels or three 56-inch panels in wide format. We currently plan for equipment move-in to
be scheduled for the second quarter of 2006 and expect to commence commercial production in the fourth quarter of 2006. We expect to spend approximately NT$35 billion to NT$38 billion for the installation of machinery and equipment at our
7.5-generation fab. As of December 31, 2004, we had not purchased any machinery or equipment for our 7.5-generation fab.



ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS



5.A. Operating Results



Overview



The TFT-LCD industry in general has been characterized by
cyclical market conditions. The industry has been subject to significant and rapid downturns as a result of imbalances between excess supply and slowdowns in demand, resulting in sharp declines in average selling prices. For example, the significant
increase in the average selling prices of large-size panels in the first half of 2002 was followed by a slowdown in demand growth in the second half of 2002, which in turn resulted in excess supply in the market and caused sharp declines in prices
in that period. As a result, the average selling prices of our large-size panels decreased by 13.0% between the second quarter and the third quarter of 2002 and further decreased by 21.7% between the



34

##### Table of Contents

third quarter and the fourth quarter of 2002. Average selling prices of our large-size panels recovered in 2003 with prices increasing by 17.3% between the
first quarter of 2003, and the fourth quarter of 2003. Average selling prices of our large size panels fluctuated throughout 2004, increasing by 12.1% between the fourth quarter of 2003 and the second quarter of 2004 and decreasing by 22.2% between
the second quarter and the third quarter of 2004 and further decreasing 17.1% between the third quarter and the fourth quarter of 2004.



Our revenues depend substantially on the average selling prices of our panels and are affected by fluctuations in those prices. The average selling prices
of our large-size panels increased by 15.6% between 2001 and 2002 and decreased by 3.1% between 2002 and 2003 and increased by 0.9% between 2003 and 2004. The change in the average selling prices of our panels and decreases in variable costs,
depreciation and amortization expenses and other fixed costs associated with the expansion of our production capacity on a per panel basis contributed to the increase in our gross margins from 16.0% in 2002 to 22.4% in 2003 and 23.6% in 2004. The
strong demand for TFT-LCD panels in 2003 resulted in a recovery in average selling prices in 2003. Strong demand continued in the first half of 2004, keeping average selling prices high; however this was offset by an oversupply of and reduced demand
for TFT-LCD panels in the second half of 2004, which resulted in average selling prices remaining relatively stable for the full year of 2004 compared to the full year of 2003. To meet demand, many TFT-LCD manufacturers, including our company, may
expand their capacity. If such expansion in capacity is not matched by a comparable increase in demand, it could lead to overcapacity and declines in the average selling prices of our panels in the future. In addition, we expect that, as is typical
in the TFT-LCD industry, the average selling prices for our existing product lines will gradually decline as the cost of manufacturing TFT-LCD panels declines and as the product becomes more commodity-like.



Production Capacity



We measure the capacity of a fab in terms of the number of substrates and the glass area of substrates that can be produced.
As of December 31, 2004, we had an annual capacity to produce approximately 311.7 million square meters of glass area of TFT-LCD panels.



Fab Construction and Ramp-Up Process



Once the design of a new fab is completed, it typically takes six to eight quarters before the fab commences commercial production, during which time we
construct the building, install the machinery and equipment and conduct trial production at the fab. An additional two to three quarters are required for the fab to be in a position to produce at the installed capacity and with high production
yield, where production yield is the number of good panels produced expressed as a percentage of the total number of panels produced. This process is commonly referred to as ramp-up. At the beginning of the ramp-up process, fixed costs,
such as depreciation and amortization, other overhead expenses, labor, general and administrative and other expenses, are relatively high on a per panel basis, primarily as a result of the low output. Variable costs, particularly raw materials and
component costs, are also relatively high on a per panel basis since production yield is typically low in the early stages of the ramp-up of a fab, resulting in greater waste of raw materials and components. In general, upon the completion of the
ramp-up process, a fab is capable of producing at its installed capacity, leading to lower fixed costs per panel as a result of higher output, and lower raw materials and component costs per panel as a result of higher production yield.



We typically construct our new fabs in phases in order to allocate our
aggregate capital expenditure across a greater period of time. As a result, the installed capacity in the early phases of production at a new fab is typically lower than the maximum capacity that can be installed at a fab.



Product Mix



Our product mix affects our sales and profitability, as the prices and costs of different size panels may vary
significantly. The larger panel sizes command higher prices, but also have higher manufacturing costs. In 2004,



35

##### Table of Contents

an increase in demand for consumer electronic products using larger TFT-LCD panels such as portable DVD players caused a shift in product mix to more medium
sized panels being produced. The continued trend toward notebook computers with larger screens and the continuing demand for TFT-LCD panels for desktop monitors as a result of the replacement of CRT monitors for TFT-LCD monitors led us to shift our
product mix to include primarily 14.1-inch and 15.4-inch panels for notebook computers and 15-, 17- and 19-inch panels for desktop monitors. Moreover, a strong demand for LCD television contributed to increased production of LCD television panels.
Our fifth-generation fabs have enabled us to produce 15-, 17- and 19-inch or larger panels more efficiently. Our sixth-generation fab will also enable us to produce larger LCD television panels. We periodically review and adjust our product mix
based on the demand for, and profitability of, the different panel sizes that we manufacture.



Critical Accounting Policies



Preparation of our consolidated financial statements requires us to make estimates and judgments that affect the amounts of our assets, liabilities, revenues and expenses. We continually evaluate these estimates, including those related to
allowances for doubtful accounts, inventories, useful lives of properties, goodwill, income tax valuation allowances, pension plans and the fair value of financial instruments. We base our estimates on historical experience and other assumptions,
which we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions and conditions. We have identified below the accounting policies that are critical to our consolidated financial
statements.



Revenue Recognition



Revenue is recognized when title to the products and risk of ownership are
transferred to the customers, which occurs principally at the time of shipment. We continuously evaluate whether our products meet our inspection standards and can reliably estimate sales returns expected to result from customer inspections.
Allowance and related provisions for sales returns are estimated based on historical experience. Such provisions are deducted from sales in the year the products are sold. There have been no changes in this policy for the last three years.



The movements of the allowance for sales returns and discounts
are as follows:

As of December 31,
2002, 2003 and 2004, the allowance for sales discounts and returns was NT$92 million, NT$46 million and NT$699 million (US$22.0 million), respectively. In 2003, we reversed certain allowances established in prior periods due to lower than expected
sales discounts and returns. For the years ended December 31, 2002, 2003, and 2004, we did not have to record any additional provisions subsequent to the year ended because actual returns and pricing discounts were lower than the estimated amounts.



Recoverability of Long-Lived Assets



Under U.S. GAAP, we review our long-lived assets and certain identifiable
intangible assets, including purchased intangible assets for impairment whenever we feel that events or changes in circumstances indicate that the carrying amounts of these assets may not be recoverable. Furthermore, under ROC and U.S. GAAP, we
review our assets held for sale for impairment whenever we feel that the fair value of these assets may be lower than the carrying amount. Judgments about the fair value of assets held for sale are generally based upon market assumptions about value
of similar assets, and are supported by third party appraisals.

##### Table of Contents

Under ROC GAAP we measure recoverability of our assets to be held and used by comparing the carrying
amount of an asset to the fair value of the asset. Under U.S. GAAP, we measure recoverability of our long-lived assets to be held and used by comparing the carrying amount of an asset to its future undiscounted net cash flows. If we consider our
assets to be impaired, the impairment we would recognize is measured by the amount by which the carrying amount of the assets exceed the fair value of the assets. No impairment indicators were noted during 2004. Furthermore, we had assets held for
sale in 2003 and 2004. As of December 31, 2003 and 2004, we recorded a provision for impairment of assets held for sale of NT$75 million and NT$136 million (US$4.3 million), respectively. The impairment of assets held for sale was classified in
non-operating expenses and losses in the statements of operations.



Allowance for Uncollectible Accounts Receivable



We evaluate our outstanding accounts receivables on a monthly basis for collectibility purposes. Our evaluation includes an analysis of the number of days outstanding for each outstanding accounts receivable account. When appropriate, we
provide a provision that is based on the number of days for which the account has been outstanding. The provision provided on each aged account is based on our average historical loss experience. There have been no changes in this policy for the
last three years.



The movements of the allowance for
uncollectible accounts are as follows:



|                             |  |          |   |  |        |  |        |  |

As of December 31,
2002, 2003 and 2004, the allowance we established for doubtful accounts was NT$39 million, NT$81 million and NT$90 million (US$2.8 million), respectively. For the years ended December 31, 2002, 2003, and 2004, we have not made any significant
changes to estimates used to determine allowances for doubtful accounts.



Realization of Inventory



Provisions for inventory obsolescence and devaluation are recorded when we determine that the amounts that will ultimately be realized are less than their cost basis, which may be affected by the number of months inventory items remain
unsold and their prevailing market prices. Additionally, our analysis of the amount we expect to ultimately realize are partially based upon forecasts of demand for our products and any change to these forecasts. There have been no changes in this
policy for the last three years.



As of December 31, 2002, 2003
and 2004, the provision for inventory obsolescence and devaluation was NT$394 million, NT$607 million and NT$1,031 million (US$32.5 million), respectively, which were classified in cost of goods sold in the statements of operations. For the years
ended December 31, 2002, 2003 and 2004, we have not made any significant changes to estimates used to determine the provisions for excess and obsolete inventory.



Recoverability of Long-Term Investments



Long-term equity investments in which we are not able to exercise significant influence over the investees operations
and financial policies (generally those in which we own less than 20% of the investees voting shares) are accounted for using the lower of cost or the quoted market value if the investee is a listed company, otherwise such investments are
accounted for using the cost method. If there is evidence indicating that a decline in the



37



---

##### Table of Contents

value of an investment is other than temporary, then the carrying amount of the investment is reduced to reflect its estimated net realizable value. Net
realizable value is determined based on its quoted market value, if listed, or its fair value based on the present value of its estimated future cash flows. For the years ended December 31, 2002, 2003 and 2004, we have not recognized any significant
impairment losses on long-term investments.



When we have the
ability to exercise significant influence over the operating and financial policies of investees (generally those in which we own between 20% and 50% of the investees voting shares) those investments are accounted for using the equity method.
The difference between the acquisition cost and the carrying amount of net equity of the investee as of the acquisition date is allocated based upon the pro rata share of the excess of fair value over the carrying value of assets on the
investees books. Such difference is reflected as a component of the investment balance and is adjusted to reflect changes in the basis of the related asset. Unallocated amounts are recorded as investor level goodwill, and are not subject to
amortization, but rather are assessed for impairment as part of the carrying amount of the investment. For example, amounts allocated to property, plant and equipment are depreciated in a manner similar to the related assets through a charge to net
investment gain recognized by equity method investments. The allocation of excess basis in equity method investments requires the use of judgments regarding, among other matters, the fair value and estimated useful lives of long lived assets.
Changes in those judgments would affect the amount and timing of amounts charged to our statement of operations.



Certain investments in which we hold less than a 20% voting interest, but are nonetheless able to exercise significant influence over the operating and
financial policies of investees through board representation or other means are also accounted for using the equity method. Significant judgment is required to assess whether we have significant influence. Factors that we consider in making such
judgment include, among other matters, participation in policymaking processes, material intercompany transactions, interchange of managerial personnel, or technological dependency.



In 2004, we purchased 126,600,000 shares of BenQ representing a 5.47% equity interest in BenQ. As we and BenQ share a common
chairman and chief executive officer, a second officer board member, and have other commercial relationships, we are deemed to have the ability to exercise significant influence over BenQ. As such, we account for our investment in BenQ under the
equity method of accounting.



Income Taxes



We are subject to the continuous examination of our
income tax returns by the ROC tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes.



As of December 31, 2004, the ending balance for our valuation allowances on
deferred tax assets was NT$8,805.0 million under ROC GAAP. If our current estimate of future profit had been higher, we would have decreased our valuation allowances accordingly. In contrast, if our current estimate of future profit had been lower,
we would have increased our valuation allowances. However, due to the complexity of calculating our valuation allowances, we are unable to provide with reasonable accuracy the amount of changes to our valuation allowances that would have resulted
based upon specific percentage changes to one or more individual factors such as our expected future revenue or profits.



Under U.S. GAAP, cumulative losses in recent years are a significant piece of negative evidence which is difficult to support a conclusion that expected
taxable income from future operations (excluding reversal of existing temporary differences) justifies recognition of deferred tax assets. We suffered losses in 2001 and also

##### Table of Contents

had a net loss in the fourth quarter of 2002. As a result, we did not use the projection of future taxable income in determining our valuation allowance for
periods through December 31, 2002. As we continue to generate taxable income from 2003 onwards, more positive evidence is available. We are using the available future taxable income projections in the near term in determining the extent of our
valuation allowance.

Net Sales



Net sales increased 60.3% to NT$168,111.6 million (US$5,296.5 million) in
2004 from NT$104,860.6 million in 2003 due to a 60.5% increase in net sales of large-size panels and a 62.0% increase in net sales of small- and medium-size panels. Net sales of large-size panels increased 60.5% to NT$148,130.6 million (US$4,667.0
million) in 2004 from NT$92,274.0 million in 2003. This increase was primarily due to an increase in unit sales. Large-size panels sold increased 59.0% to 18,851.4 thousand panels in 2004 from 11,852.7 thousand panels in 2003. The average selling
price per panel of our large-size panels remained relatively stable, increasing 0.9% to NT$7,858 (US$247.6) in 2004 from NT$7,785 in 2003, primarily as a result of an increase in average selling prices in the first half of 2004 caused by strong
consumer demand which was partially offset by a decrease in average selling prices in the second half of 2004 resulting from an oversupply of panels in the TFT-LCD industry. The increase in unit sales of large-size panels was due to our
expanded production capacity and stimulated demand as a result of decreasing average selling prices in the second half of 2004. The increased demand was primarily due to consumers continuing to replace their CRT monitors with TFT-LCD monitors,
increased bundling of TFT-LCD monitors and PCs by brand companies and increased demand for both notebook computers and LCD television.



Net sales of small- to medium-size panels increased 62.0% to NT$19,208.0 million (US$605.2 million) in 2004 from NT$11,855.8 million in 2003. The increase
in net sales of small- to medium-size panels was primarily due to an increase in unit sales. Unit sales of our small- to medium-size panels increased 55.3% to 33,289.5 thousand panels in 2004 from 21,431.2 thousand panels in 2003. The average
selling price per panel of our small- to medium-size panels increased 4.3% to NT$577 (US$18.2) in 2004 from NT$553 in 2003, primarily as a result

of a shift in product mix to more medium-size panels being produced due to increasing demand for consumer electronic products using medium-sized TFT-LCD
panels such as portable DVD players. The increase in unit sales of small- to medium-size panels was primarily due to new products which use small- to medium-size panels being introduced in the market, resulting in new customers, and the growing
acceptance and use of TFT-LCD panels for consumer electronics products.



Cost of Goods Sold



Cost of goods sold
increased 57.8% to NT$128,468.3 million (US$4,047.5 million) in 2004 from NT$81,398.9 million in 2003. This increase was primarily as a result of an increase in our requirements for raw materials and components and an increase in depreciation and
amortization expenses. Raw materials and component costs increased 60.3% in 2004 as compared to 2003, primarily as a result of an increase in unit sales of our panels. While we expected the average market prices of raw materials and components to
decline in 2004 compared to 2003, despite the fluctuation of market prices for glass substrates, color filters and driver integrated circuits throughout 2004, the average market prices of raw materials and components remained relatively stable in
2004 compared to 2003. Overhead expenses, including depreciation and amortization expenses, increased 56.4% in 2004 compared to 2003, primarily due to increased production costs and capacity at our fabs and increased depreciation expenses associated
with our in-house color filter production facility and our second fifth-generation fab, both of which commenced commercial production in 2004. Direct labor costs increased 27.6% in 2004 compared to 2003, primarily as a result of an increased number
of employees due to our increased production capacity, the ramp-up of our second fifth-generation fab, the construction of our sixth-generation fab and the expansion of our module-assembly facilities in Suzhou, PRC.



As a percentage of net sales, cost of goods sold decreased slightly to 76.4%
in 2004 from 77.6% in 2003. This decrease was primarily as a result of a decrease in our cost of goods sold per panel for large-size panels and an increase in our net sales. The decrease in our cost of goods sold per panel for large-size panels was
primarily as a result of lower fixed costs per panel for large-size panels. Fixed costs per panel (which include depreciation and amortization expenses, direct labor costs and utility and other overhead expenses) for large-size panels decreased due
to improved production efficiency through yield rate improvement at our fifth-generation fabs, which was partially offset by a lower utilization rate in the second half of 2004.



Gross Profit



Gross profit increased 69.0% to NT$39,643.3 million (US$1,249.0 million) in 2004 from NT$23,461.8 million in 2003. Gross margin, which is gross profit
divided by net sales, was 23.6% in 2004 as compared to 22.4% in 2003. The improvement in gross margin was primarily as a result of an increase in net sales.



Under U.S. GAAP, gross profit increased 64.9% to NT$32,855.6 million (US$1,035.1 million) in 2004 from NT$19,919.7 million in 2003. Gross margin, which is
gross profit divided by net sales, was 19.5% in 2004 as compared to19.0% in 2003. The improvement in gross margin was primarily as a result of an increase in net sales, which resulted in lower per unit costs from lower absorption of fixed costs.



Operating Expenses



Operating expenses increased 52.9% to NT$11,036.0 million (US$347.7 million)
in 2004 from NT$7,217.0 million in 2003. As a percentage of net sales, operating expenses decreased to 6.6% in 2004 from 6.9% in 2003. The increase in operating expenses was primarily as a result of an increase in unit sales of our panels in 2004.
Selling expenses increased 75.4% to NT$2,447.1 million (US$77.1 million) in 2004 from NT$1,395.0 million in 2003, primarily due to increases in selling commissions, transportation costs and marketing expenses as a result of increased sales. Selling
expenses as a percentage of net sales increased to 1.5% in 2004 from 1.4% in 2003. General and administrative expenses increased 46.9% to NT$3,577.3 million (US$112.7 million) in 2004 from NT$2,435.6 million in 2003, primarily as a result of the
ramp-up costs at our fifth-generation fabs prior to

commercial production at such facilities and the establishment of our sixth-generation fab. General and administrative expenses as a percentage of net sales
decreased slightly to 2.1% in 2004 from 2.3% in 2003. Research and development expenses increased 48.0% to NT$5,011.6 million (US$157.9 million) in 2004 from NT$3,386.4 million in 2003, primarily due to the additional expenses associated with the
installation of equipment at our new research and development facility, the AUO Technology Center, and royalties and license fees related to the transfer of new technologies. Research and development expenses as a percentage of net sales decreased
to 3.0% in 2004 from 3.2% in 2003.



Under U.S. GAAP, operating
expenses increased 92.8% to NT$12,686.8 million (US$399.7 million) in 2004 from NT$6,581.8 million in 2003. As a percentage of net sales, operating expenses increased to 7.5% in 2004 from 6.3% in 2003. The increase in operating expenses was
primarily due to expansion, increase of sales related expenses as a result of an increase in unit sales of our panels and an increase of employee compensation expense. Selling expenses increased 62.5% to NT$2,093.2 million (US$65.9 million) in 2004
from NT$1,288.3 million in 2003, primarily due to increases in selling commissions, transportation costs and marketing expenses as a result of increased sales, the increase of employee compensation costs. Selling expenses as a percentage of net
sales was about the same in 2004 and in 2003. General and administrative expenses increased 121.5% to NT$6,232.8 million (US$196.4 million) in 2004 from NT$2,813.9 million in 2003, primarily as a result of the ramp-up costs at our fifth-generation
fabs prior to commercial production at such facilities and the establishment of our sixth-generation fab, and a result of the increase of compensation costs. General and administrative expenses as a percentage of net sales increased to 3.7% in 2004
from 2.7% in 2003. Research and development expenses increased 75.9% to NT$4,360.8 million (US$137.4 million) in 2004 from NT$2,479.6 million in 2003, primarily due to the additional expenses associated with the installation of equipment at our new
research and development facility, the AUO Technology Center, and a result of the increase of compensation costs. Research and development expenses as a percentage of net sales increased to 2.6% in 2004 from 2.4% in 2003.



Operating Income and Operating Margin



As a result of the foregoing, operating income increased 76.1% to
NT$28,607.3 million (US$901.3 million) in 2004 from NT$16,244.8 million in 2003, and operating margin increased to 17.0% in 2004 from 15.5% in 2003.



Under U.S. GAAP, as a result of the foregoing, operating income increased 51.2% to NT$20,168.8 million (US$635.4 million) in 2004 from NT$13,337.9 million
in 2003, and operating margin decreased to 12.0% in 2004 from 12.7% in 2003.



Net Non-Operating Expenses and Losses



We had net non-operating expenses and losses of NT$583.1 million (US$18.4 million) in 2004 compared to net non-operating expenses and losses of NT$671.5 million in 2003. We had lower net non-operating expenses and
losses in 2004 as compared to 2003 primarily as a result of investment gain on equity method investments and a decrease in net interest expense. We had a gain on equity method investments of NT$34.3 million (US$1.1 million) compared to a loss of
NT$14.4 million in 2003. We had a net interest expense of NT$621.4 million (US$19.6 million) in 2004 compared to a net interest expense of NT$658.1 million in 2003, principally as a result of a reduction in the amount of average outstanding debt and
lower interest rates.



Under U.S. GAAP, we had net
non-operating expenses and losses of NT$1,592.9 million (US$50.1 million) in 2004 compared to net non-operating expenses and losses of NT$852.6 million in 2003. We had higher net non-operating expenses and losses in 2004 as compared to 2003
primarily as a result of an impair loss on securities available-for-sale which was partially offset by an investment gain on equity method investments. We recognized other-than-temporary impairment losses on securities available-for-sale of NT$922.9
million (US$29.1 million) in 2004 compared to none in 2003. We had a gain on equity method investments of NT$279.7 million (US$8.8 million) in 2004 compared to a loss of NT$177.8 million in 2003.

Income Tax Expense



We recorded an income tax expense of NT$61.3 million (US$1.9 million) in 2004 compared to an income tax benefit of NT$86.7
million in 2003. We recorded an income tax expense in 2004 primarily due to income tax being assessed against us as a result of an increase in net income. While we used a portion of our outstanding tax credits to offset the income tax amount owed,
the amount of tax credits that may be applied in any year is limited to 50% of the income tax payable for that year. We recorded an income tax benefit in 2003 due primarily to the fact that we generated more investment tax credits, combined with the
recognition of additional net deferred income tax assets generated in 2003 due to our assessment that we would be able to realize certain of our deferred tax assets based on future profitability.



Under U.S. GAAP, we recorded an income tax expense of NT$463.4 million
(US$14.6 million) in 2004 compared to an income tax benefit of NT$3,230.1 million in 2003. We did not use the projection of future taxable income in determining the deferred tax asset valuation allowance for periods through December 31, 2002.
However, as we continue to generate taxable income from 2003 onwards, more positive evidence is available. We are using the available future taxable income projections in determining the size of the valuation allowance. As a result, we released a
portion of the deferred tax asset valuation allowance in 2003 and the income tax benefit increased in 2003 by NT$1,869 million (US$58.9 million).



Net Income



As a result of the foregoing, net income increased 78.6% to NT$27,962.9 million (US$881.0 million) in 2004 from NT$15,659.9 million in 2003.



Under U.S. GAAP, as a result of the foregoing, net income increased 15.3%
to NT$18,112.5 million (US$570.7 million) in 2004 from NT$15,715.4 million in 2003.



For the Years Ended December 31, 2003 and 2002



Net Sales



Net sales increased 38.5% to
NT$104,860.6 million in 2003 from NT$75,689.2 million in 2002 due to a 38.0% increase in net sales of large-size panels and a 76.1% increase in net sales of small- and medium-size panels. Net sales of large-size panels increased 38.0% to NT$92,274.0
million in 2003 from NT$66,852.5 million in 2002. The increase in net sales of large-size panels was primarily due to an increase in unit sales, offset by a decrease in average selling prices. Large-size panels sold increased 42.4% to 11,852.7
thousand panels in 2003 from 8,321.6 thousand panels in 2002. The average selling price per panel of our large-size panels decreased 3.1% to NT$7,785 in 2003 from NT$8,034 in 2002, primarily as a result of decreases in average selling prices
resulting from an oversupply of panels in the TFT-LCD industry during the second half of 2002. The increase in unit sales of large-size panels was due to our expanded production capacity and stimulated demand as a result of decreasing average
selling prices. The increased demand was reflected in the increased rate of replacement of TFT-LCD for CRT monitors, increased bundling of TFT-LCD monitors and PCs by brand companies and increased demand for notebook computers.



Net sales of small- to medium-size panels increased 76.1% to NT$11,855.8
million in 2003 from NT$6,731.4 million in 2002. The increase in net sales of small- to medium-size panels was primarily due to an increase in unit sales, offset by a decrease in average selling prices. Unit sales of our small- to medium-size panels
increased 135.7% to 21,431.2 thousand panels in 2003 from 9,092.1 thousand panels in 2002. The average selling price per panel of our small- to medium-size panels decreased 25.3% to NT$553 in 2003 from NT$740 in 2002, primarily as a result of
intense competition and shift in product mix. The increase in unit sales of small- to medium-size panels was due to increased demand as a result of wider industry acceptance of the use of TFT-LCD panels for consumer electronics products.

Cost of Goods Sold



Cost of goods sold increased 28.0% to NT$81,398.9 million in 2003 from NT$63,606.2 million in 2002. This increase was
primarily as a result of an increase in our requirements for raw materials and components and an increase in depreciation and amortization expenses. Raw materials and component costs increased 22.4% in 2003 as compared to 2002, primarily as a result
of an increase in unit sales of our panels, partially offset by decreases in average market prices of raw materials and components. Overhead expenses, including depreciation and amortization expenses, increased by 40.3% in 2003 compared to 2002,
primarily due to increased production costs and the purchase of additional equipment and machinery for our fabs. Direct labor costs increased by 29.5% in 2003 compared to 2002, primarily as a result of an increased number of employees due to our
increased production capacity and the ramp-up of our fifth-generation fabs and our module-assembly facilities in Suzhou, PRC.



As a percentage of net sales, cost of goods sold decreased to 77.6% in 2003 from 84.0% in 2002. This decrease was primarily as a result of a decrease in
our cost of goods sold per panel for large-size panels and an increase in our net sales. The decrease in our cost of goods sold per panel for large-size panels was primarily as a result of decreases in raw materials and component costs and lower
fixed costs per panel for large-size panels. The decrease in raw materials and component costs per panel for large-size panels was primarily due to decreases in the average market prices of raw materials and components and the introduction of new
product designs with lower component costs. Fixed costs per panel (which include depreciation and amortization expenses, direct labor costs and utility and other overhead expenses) for large-size panels decreased due to improved production
efficiency through yield rate improvement and advanced new generation technologies and economies of scale realized at our fabs.



Gross Profit



Gross profit increased 94.2% to NT$23,461.8 million in 2003 from NT$12,083.0 million in 2002. Gross margin, which is net sales less cost of goods sold,
was 22.4% in 2003 as compared to 16.0% in 2002. The improvement in gross margin was primarily as a result of an increase in net sales due to an increase in unit sales and a substantial reduction in cost of goods sold per panel for most of our panels
sold.



Operating Expenses



Operating expenses increased 65.2% to NT$7,217.0 million in 2003 from
NT$4,369.1 million in 2002. As a percentage of net sales, operating expenses increased to 6.9% in 2003 from 5.8% in 2002. The increase in operating expenses was primarily as a result of an increase in unit sales of our panels in 2003. Selling
expenses increased 168.3% to NT$1,395.0 million in 2003 from NT$520.0 million in 2002, primarily due to increases in selling commissions, transportation costs and marketing expenses as a result of increased sales. Selling expenses as a percentage of
net sales increased to 1.3% in 2003 from 0.7% in 2002. Administrative expenses increased 50.7% to NT$2,435.6 million in 2003 from NT$1,616.0 million in 2002, primarily as a result of the ramp-up costs at our fifth-generation fabs prior to commercial
production at such facilities. General and administrative expenses as a percentage of net sales increased slightly to 2.3% in 2003 from 2.1% in 2002. Research and development expenses increased 51.6% to NT$3,386.4 million in 2003 from NT$2,233.1
million in 2002, primarily due to the additional expenses for the development of advanced process and product technologies. Research and development expenses as a percentage of net sales increased to 3.2% in 2003 from 3.0% in 2002.



Operating Income and Operating Margin



As a result of the foregoing, operating income increased 110.6% to
NT$16,244.8 million in 2003 from NT$7,713.9 million in 2002, and operating margin increased to 15.5% in 2003 from 10.2% in 2002.



Net Non-Operating Expenses and Losses



We had net non-operating expenses and losses of NT$671.5 million in 2003 compared to net non-operating expenses and losses of NT$1,691.1 million in 2002.
We had lower net non-operating expenses and losses in 2003

##### Table of Contents

as compared to 2002 primarily as a result of realized and unrealized gains in short-term investments and a decrease in net interest expense. We had a gain on
market price recovery of short-term investments of NT$126.9 million in 2003, as compared to a short-term investment permanent impairment loss of NT$650.6 million in 2002, primarily as a result of an improvement in the market prices of our short-term
investments due to the recovery of market conditions on the Taiwan Stock Exchange. The short-term investment permanent impairment loss in 2002 was due primarily to the write-off of our short-term investment in PixTech in the amount of NT$523.7
million. We had a net interest expense of NT$658.1 million in 2003 compared to a net interest expense of NT$951.1 million in 2002, principally as a result of lower levels of debt and lower interest rates.



Income Tax Benefit



We recorded an income tax benefit of NT$86.7 million in 2003 compared to an
income tax expense of NT$0.1 million in 2002. We recorded an income tax benefit in 2003 due primarily to the fact that we generated more investment tax credits, combined with the recognition of additional net deferred income tax assets generated in
2003 due to our assessment that we would be able to realize certain of our deferred tax assets based on future profitability.



Net Income



As a result of the foregoing, net income increased 160.0% to NT$15,659.9 million in 2003 from NT$6,022.7 million in 2002.



Inflation



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 applicable to us is 25%. Prior to January 20, 2001, the corporate income tax rate in
Taiwan applicable to us was 20% for our products produced in the Hsinchu Science Park and 25% for our products produced elsewhere in Taiwan. However, we did not generate any income in any year except 2000, 2002, 2003 and 2004. In 2000, although we
generated income before tax, we applied certain loss carryforwards that we accumulated from previous years to offset the tax liability to which we could otherwise have been subject. In 2003, we recorded an income tax benefit due primarily to the
fact that we generated more investment tax credits and recognized additional net deferred income tax assets. As a result, we did not incur any income tax expense during any of our fiscal years, except 2002 and 2004.



Recognition of Deferred Tax Assets



Our valuation allowance provided on deferred tax assets is calculated
differently under ROC GAAP than under U.S. GAAP. This difference has a significant impact on us because we have a significant amount of deferred tax assets as a result of the various tax credits available to us under ROC governmental tax incentive
programs and net operating loss carryforwards. Please see note 22 to our consolidated financial statements included elsewhere in this annual report for further discussion and quantification of these differences. The net deferred income tax assets we
are able to recognize under ROC GAAP as of December 31, 2004 amounted to NT$2,970.4 million (US$93.6 million). This recognition of net deferred tax assets under ROC GAAP resulted primarily from the ability to consider our projection of income before
tax for future years. If we do not achieve the projection of income before tax for future years, the amount of the deferred tax assets recognized may be significantly reduced.



Tax Exemptions



Based on our status as a company engaged in the TFT-LCD business in Taiwan, all income attributable to the use of equipment that we purchase, in part or
in whole, with proceeds we raise through share offerings, may

be exempted from corporate income tax in Taiwan if our shareholders determine to allow us, instead of the shareholders themselves, to use these tax
exemptions. In addition, income attributable to the use of equipment that we purchase, in whole or in part, with retained earnings that we capitalize, may be exempted from corporate income tax in Taiwan. These exemptions typically apply for four or
five consecutive years, commencing in a year to be designated by us within two years following the commencement of commercial production using such equipment. We set forth below certain information with respect to our tax exemptions:

If we make a qualified rights offering, our shareholders will be entitled,
pursuant to a majority vote at a shareholders meeting held within two years after the rights offering, to elect to receive a tax credit for individual

shareholders of up to 10% (which percentage is decreased by 1% every two years from 2000) or for corporate shareholders of up to 20% of their subscription
amount against taxes payable within five years after expiration of the first three years of investment, during which period such shareholders are required to hold onto their investment in order to utilize the tax credit. For individual holders,
except for the last year of that period, the tax credit deductible shall not exceed 50% of the total income tax payable by such shareholder in a particular year. Even if the shareholders elect to receive the shareholders tax credit, it is
unlikely that ADS holders would be able to benefit from such tax credits. The ROC statute governing this tax credit does not expressly prohibit holders of ADSs from benefiting from such tax credit. However, in practice, even if an ADS holder may
have other ROC sources of income against which to use the tax credit, ADS holders would not be able to prove that they meet the holding requirement necessary to claim the tax credit.

As of December 31, 2004, we have loss carryforwards of NT$2,393.7 million (US$75.4 million) available.



Tax Credits



We also benefit from certain tax credits under ROC law that may be applied
toward reducing our tax liabilities. Prior to April 2002, we received tax credits at a rate of 10% of the purchase price in connection with our purchase of imported equipment and at a rate of 20% of the purchase price in connection with our purchase
of locally manufactured equipment. As a result of the ROC becoming a member of the World Trade Organization, the ROC Ministry of Economic Affairs amended the tax credit rules in April 2002 to adopt a tax credit at a rate of 13% to be applied to the
purchase of equipment, regardless of the location of production of the equipment. This rate was subsequently reduced to 11% in July 2004. We also receive tax credits at a rate of 10% for the purchase of production technology and at a rate of 13% for
the purchase of pollution control equipment. As of December 31, 2004, we had accumulated NT$10,541.5 million (US$332.1 million) of these tax credits. These tax credits are expected to expire four years after the end of the year in which we received
the equipment. As of December 31, 2004, NT$1,712.1 million (US$53.9 million), NT$2,285.7 million (US$72.0 million), NT$1,952.1 million (US$61.5 million) and NT$4,591.6 million (US$144.7 million) of these tax credits are expected to expire in 2005,
2006, 2007 and 2008, respectively.



We also benefit from other
tax credits of up to 30% of certain research and development and employee training expenses. If the amount of these expenses that we incur in any year exceeds the average of such expenses for the proceeding two years, an additional 50% of the excess
amount may be included in the applicable tax credit for such year. As of December 31, 2004, we had accumulated NT$910.4 million (US$28.7 million) of these tax credits. These tax credits are expected to expire four years after the year expenses are
incurred. As of December 31, 2004, NT$65.4 million (US$2.1 million), NT$189.9 million (US$6.0 million), NT$252.6 million (US$8.0 million) and NT$402.5 million (US$12.6 million) of these tax credits are expected to expire in 2005, 2006, 2007 and
2008, respectively.



Tax on Retained
Earnings



In 1997, the ROC Income Tax Law was amended
to integrate the corporate income tax and shareholder dividend tax. Under the amendment, after-tax earnings generated from January 1, 1998 and not distributed to shareholders as dividends in the following year will be subject to a 10% retained
earnings tax. See Item 10. Additional InformationTaxationROC Tax ConsiderationsRetained Earnings Tax. As a result, if we do not distribute as dividends in any year all of our annual retained earnings generated in the
preceding year, our applicable corporate income tax rate may exceed 25% for such year.



5.B. Liquidity and Capital Resources



We need cash primarily for capacity expansion and working capital. Although we have historically been able to meet our working capital requirements through cash flow from operations, our ability to expand our



46



---

##### Table of Contents

capacity has been largely dependent upon, and to a certain extent will continue to depend upon, our financing capability through the issuance of equity
securities, long-term borrowings and the issuance of convertible and other debt securities. If adequate funds are not available, whether on satisfactory terms or at all, we may be forced to curtail our expansion plans, including plans for newer
generation fabs. Our ability to meet our working capital needs from cash flow from operations will be affected by our business conditions which in turn may be affected by several factors. Many of these factors are outside of our control, such as
economic downturns and declines in the average selling prices of our products caused by oversupply in the market. The average selling prices of our existing product lines are reasonably likely to be subject to further downward pressure in the
future. To the extent that we do not generate sufficient cash flow from our operations to meet our cash requirements, we may need to rely on external borrowings and securities offerings. Other than as described below in Off-Balance Sheet
Arrangements, 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.



As of December 31, 2004, our primary source of liquidity was NT$17,797.7
million (US$560.7 million) of cash and cash equivalents and NT$1,586.5 million (US$50.0 million) of short-term investments. As of December 31, 2004, we had total short-term credit lines of NT$17,015.1 million (US$536.1 million), of which we had
borrowed NT$6,183.0 million (US$194.8 million) as of December 31, 2004. All of our short-term facilities are revolving with a term of one year, which may be extended for terms of one year each with lender consent. We are subject to restrictions on
the sale, lease, transfer or other disposal of our assets under some of our short-term loan facilities. Our repayment obligations under our short-term loans are unsecured. We believe that our existing credit lines under our short-term loans,
together with cash generated from our operations, are sufficient to finance our current working capital needs.



As of December 31, 2004, we had outstanding long-term borrowings of NT$47,418.5 million (US$1,494.0 million). The interest rates in respect of these
long-term borrowings are variable, and as of December 31, 2004 ranged between 1.8% and 5.0% per year.



In November 2001, we issued an aggregate principal amount of NT$10,000.0 million of convertible bonds due November 2008. The convertible bonds have been
fully converted into our shares as of October 2003. The convertible bonds had a stated interest rate of 2.0% and an effective interest rate of 4.50%. The initial conversion price was NT$15.80 per share, subject to adjustment. The conversion price
was adjusted to NT$14.9 per share based on the resolution of our board of directors meeting on June 16, 2003, to reflect the stock dividend distributed in 2003. As of December 31, 2002 and 2003, the total principal amount of convertible bonds
which had been converted into our shares totaled NT$8,748.7 million and NT$10,000 million, respectively, which amounted to NT$5,537.1 million and NT$6,376.0 million, respectively, for our shares and a premium of NT$3,315.3 million and NT$3,795.0
million, respectively, recorded as capital surplus.



In
November 2003, we entered into a NT$35.0 billion seven-year syndicated credit facility, for which International Commercial Bank of China acted as the agent bank, for the purpose of funding the construction and purchase of machinery and equipment at
our fabs. The syndication agreement for this facility contains covenants that require us to maintain certain financial ratios. Our obligations under this credit facility are secured by certain of our equipment and machinery. As of December 31, 2004,
NT$9.0 billion has been drawn down under this credit facility. We issued NT$6.0 billion secured corporate bonds under this credit facility in April 2004.



In June 2004, we entered into a NT$55 billion and US$150 million seven-year syndicated credit facility, for which the Bank of Taiwan acted as the agent
bank, for the purpose of funding the construction and purchase of machinery and equipment at our fabs. The syndication agreement for this facility contains covenants that require us to maintain certain financial ratios. Our obligations under this
credit facility are secured by certain of our equipment and machinery. As of December 31, 2004, NT$3 billion has been drawn down under this credit facility. We issued NT$6.0 billion secured corporate bonds under this credit facility in June 2005.



In June 2004, we issued an aggregate of 30,000,000 ADSs
representing 300,000,000 shares of our common stock. The net proceeds from the offering were approximately NT$15,967.2 million (US$503.1 million). We

##### Table of Contents

used the net proceeds for the construction of and purchase of equipment and machinery for our production facilities, including the ramping up of our
fifth-generation fabs and the construction of our sixth-generation fab.



Our long-term loans and facilities contain various financial and other covenants that could trigger a requirement for early payment. Among other things, these covenants require the maintenance of certain financial ratios, such as liquidity
ratio, indebtedness ratio, interest coverage ratio and other technical requirements. In general, covenants in the agreements governing our existing debt, and debt we may incur in the future, may materially restrict our operations, including our
ability to incur debt, pay dividends, make certain investments and payments and encumber or dispose of assets. A default under one debt instrument may also trigger cross-defaults under our other debt instruments. An event of default under any debt
instrument, if not cured or waived, could have a material adverse effect on our liquidity, as well as our financial condition and operations.



The carrying amount of our assets pledged as collateral to secure our obligations under our long-term borrowings and bonds, including building, machinery
and equipment, amounted to NT$89,345.0 million (US$2,814.9 million) as of December 31, 2004.



Net cash provided by operating activities amounted to NT$20,821.7 million in 2002, NT$37,041.5 million in 2003 and NT$49,393.6 million (US$1,556.2 million) in 2004. Our depreciation and amortization was NT$12,989.9
million in 2002, NT$16,294.6 million in 2003 and NT$25,309.3 million (US$797.4 million) in 2004. Our notes and accounts payable increased NT$1,322.0 million in 2002, NT$11,413.0 million in 2003 and NT$5,026.6 million (US$158.4 million) in 2004.
Increases in depreciation and amortization were primarily due to increased capital investment for the expansion of our production capacity. Our depreciation and amortization and increases in our notes and accounts payable were partially offset by
increases in notes and accounts receivable of NT$1,171.5 million in 2002, NT$6,894.2 million in 2003 and NT$4,541.4 million (US$143.1 million) in 2004 and increases in inventories of NT$1,770.7 million in 2003 and NT$6,517.3 million (US$205.3
million) in 2004.



Net cash used for investing activities was
NT$18,125.0 million in 2002, NT$40,339.4 million in 2003 and NT$87,010.2 million (US$2,741.3 million) in 2004. Net cash used for investing activities primarily reflected capital expenditures for property, plant and equipment of NT$18,035.3 million
in 2002, NT$39,300.6 million in 2003 and NT$81,868.7 million (US$2,579.4 million) in 2004. These capital expenditures were primarily funded with net cash provided by operating activities and financing activities, primarily from long-term bank
borrowings and the issuance of shares.



Net cash provided by
financing activities was NT$16,754.3 million in 2002, reflecting primarily our share issuance totaling NT$19,170.3 million, partially offset by our repayment of long-term loans and bonds of NT$5,104.1 million. Net cash used by financing activities
was NT$4,672.6 million in 2003, reflecting primarily our repayments of long-term loans and bonds of NT$10,792.1 million, partially offset by borrowings of NT$8,740.4 million under long-term loans. Net cash provided by financing activities was
NT$37,615.2 million (US$1,185.1 million), in 2004, reflecting primarily our issuance of shares in connection with our ADS follow-on offering totaling NT$15,967.2 million (US$503.1 million) and long-term loans and bonds of NT$28,315.8 million
(US$892.1 million) partially offset by our repayment of long-term loans and bonds of NT$6,892.1 million (US$217.1 million) and a cash dividend distribution of NT$5,208.3 million (US$164.1 million).



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

We are sometimes required to prepay our purchases of land and equipment. Prepayments for purchases of
land are the result of a standard processing procedure by the ROC government related to the transfer of legal title. As of December 31, 2002, 2003 and 2004, our prepayments for purchases of land amounted to NT$30 million, NT$28 million and NT$0
million, respectively. Prepayments for purchases of equipment result from contractual agreements involving down payments to suppliers when the equipment is ordered by us. As of December 31, 2002, 2003 and 2004, prepayments for purchases of equipment
amounted to NT$10,055 million, NT$11,753 million and NT$38,037.4 million (US$1,198.4 million), respectively.



For the year ended December 31, 2004, our capital expenditures amounted to NT$83,047.8 million (US$2,616.5 million), primarily for purchase of equipment
to build our sixth-generation fab, including the color filter production facilities to be located at our sixth-generation fab, and the expansion of our existing fabs and our module-assembly operations.



We estimate our capital expenditures to be approximately NT$70.0 billion to
NT$80.0 billion for 2005, primarily for the purchase of equipment to complete our third fifth-generation fab, including a second color filter production facility, the ramp-up of our sixth-generation fab and the establishment of our planned
7.5-generation fab. As of July 1, 2005, we have made commitments to purchase approximately NT$51.7 billion of equipment and machinery. We may adjust the amount of our capital expenditures upward or downward based on cash flow from operations, the
progress of our expansion plans, and market conditions.



We
believe that our existing cash, cash equivalents, short-term investments, expected cash flow from operations and borrowings under our existing and future credit facilities will be sufficient to meet our capital expenditure, working capital, cash
obligations under our existing debt and lease arrangements and other requirements for at least the next 12 months. We frequently need to invest in new capacity to improve our economies of scale and reduce our production costs, which may 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.



5.C. Research and Development



We incurred research and development costs of NT$2,233.1 million, NT$3,386.4 million and NT$5,011.5 million (US$157.9 million) in 2002, 2003 and 2004, respectively, which represented 3.0%, 3.2% and 3.0%, respectively, of our net sales.



Our research and development activities are principally
directed toward advancing our technologies in key components, manufacturing processes and product development, with the objective of improving the features of our products to bring added value to our customers in addition to design products that
meet their specific requirements. We have a product development team dedicated to each of our primary product categories, including notebook computers, desktop monitors, LCD TVs, consumer electronics and general industrial applications. Each of
these teams focuses on development of our existing products for its respective markets. To support our fabs, we maintain a centralized research and development team that works to improve our manufacturing processes, as well as a team of technical
support personnel that focuses on computer integrated manufacturing. We also have two research and development teams that are dedicated to the development of LTPS and OLED, respectively. In addition, we have two research and development teams to
explore new design platforms for next-generation displays. Finally, we have one research and development team that focuses on manufacturing yield and key component vendors. Monetary incentives are provided to our employees if research projects
result in successful patents. As of December 31, 2004, we employed approximately 717 research and development engineers in our company.



We plan to continue to increase our spending on research and development with the goal of improving our TFT-LCD manufacturing process and developing new
TFT-LCD products such as high-resolution 17-inch or



49



---

##### Table of Contents

larger panels for desktop monitors and 26-inch or above panels for television. We are also developing alternative technologies such as LTPS and OLED display.
In particular, we are developing color active-matrix OLED technology for small- to medium-size panels, which we expect to be utilized in products such as mobile phones and digital still cameras.



We completed the establishment of a dedicated flat panel research and
development center, the AUO Technology Center, in the third quarter of 2004. The research activities at the AUO Technology Center have initially been divided into several general areas, including advanced technology development in new liquid crystal
materials, new system electronics, new backlight unit technologies, image and color processing, OLED, LTPS and plasma display. In addition to new product development and module processing, the AUO Technology Center also focuses on improving our
current TFT-LCD panel product and manufacturing process technologies. As of December 31, 2004, we had invested a total of NT$879.0 million (US$27.7 million) in the AUO Technology Center.



5.D. Trend Information



For
trend information, see Item 5. Operating and Financial Review and ProspectsOperating Results.



5.E. Off-Balance Sheet Arrangements



We have, from time to time, entered into non-derivative financial instruments, including letters of credit to finance or secure our purchase payment obligations. As of December 31, 2004, we had off-balance sheet outstanding letters of
credit of US$9.7 million and JP¥3,144.1 million. In addition, we have entered into interest rate swap transactions to hedge our interest rate exposure arising out of our long-term borrowing facilities. As of December 31, 2004, we had interest
rate swaps contracts with a total notional amount of NT$24.5 billion and with the maturity dates ranging from January 2008 to July 2009. We also entered into foreign currency forward contracts to economically hedge our existing assets and
liabilities denominated in foreign currencies and identifiable foreign currency purchase commitments. As of December 31, 2004, we had outstanding foreign currency forward contracts of US$518.5 million and NT$6,872 million with settlement dates
ranged from January to March 2005.



5.F. Tabular Disclosure of Contractual Obligations



The following tables set forth our contractual obligations and commitments with definitive payment terms which will require significant cash outlays in the future as of December 31, 2004.

sixth-generation and our third fifth-generation fabs, together with the color filter production facilities housed at such fabs. As of December 31, 2004, we had made commitments of approximately NT$31.3 billion (US$1.0 billion), primarily relating to
the sixth-generation fab and color filter production, and approximately NT$23.5 billion (US$0.7 billion), relating to the third fifth-generation fab, which commitments may be cancelled subject to the payment of certain penalties.

In addition to the contractual obligations set
forth above, we also have continuing obligations to make cash royalty payments under our technology license agreements, the amounts of which are determined based on net sales of our panels.



We have not entered into any financial guarantees or similar commitments to
guarantee the payment obligations of non-affiliated third parties. In addition, we do not have any written options on non-financial assets. Our long-term loan and lease agreements include provisions that require early payment under certain
conditions. The terms of our credit facilities for long-term borrowings also contain financial covenants, including current and debt-equity ratios 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, 2004, we were in compliance with all financial covenants and other technical requirements under our credit
facilities.

Below is a discussion
of certain material differences between ROC GAAP and U.S. GAAP. See note 22 to our consolidated financial statements for a complete discussion of significant differences between ROC GAAP and U.S. GAAP.



Business Combination



We completed our merger with Unipac on September 1, 2001 through the
issuance of 1,512,281,607 of our shares in exchange for all of the outstanding shares of Unipac. Under ROC GAAP, the merger was accounted for using the pooling-of-interests method and, accordingly, all of our consolidated financial statements for
prior periods included in this prospectus have been restated to include the results of operations, financial position and

##### Table of Contents

cash flows of Unipac. Further, according to the ROC Company Law, the excess of Unipacs net assets over the par value of our shares issued for
completion of the merger has been appropriated from unappropriated earnings and recorded as capital surplus. Under U.S. GAAP, the merger has been accounted for as the acquisition of Unipac, using the purchase method of accounting. Under purchase
accounting, the aggregate purchase price of NT$39,636.9 million was calculated based on the market value of our shares issued and this amount was allocated to the assets acquired and liabilities assumed based on their respective fair values. The
market value of our shares was based on the average market price of our shares over the five-day period before and after the terms of the acquisition were agreed upon and announced. Our management is responsible for the determination of the fair
value of the assets acquired, including identifiable intangible assets, and liabilities assumed of Unipac. In determining such fair values, management considered a number of factors, including valuation reports by third parties. Based on the results
of these valuations and our best estimates of fair value, we allocated the purchase price to the assets acquired and the liabilities assumed in accordance with U.S. GAAP. The difference between the purchase price and the fair value of the net assets
that we acquired, including identifiable intangible assets, has been recorded as goodwill. The financial results of Unipac prior to the acquisition date of September 1, 2001 have been excluded from our U.S. GAAP results of operations.



We recorded NT$8,730.4 million of acquired intangible assets as part of the
purchase price for Unipac, of which NT$53.5 million was assigned to in-process research and development assets that were then written off at the date of acquisition in accordance with Financial Accounting Standards Board, or FASB, Interpretation No.
4, Applicability of FASB Statement No. 2 to Business Combinations Accounted for by the Purchase Method. Those write-offs were included in research and development expenses in 2001. The remaining NT$8,676.9 million of acquired intangible
assets have a weighted average useful life of approximately 88 months and no estimated residual value. These intangible assets include large-size TFT-LCD product and manufacturing process technologies of NT$3,123.6 million and small- to medium-size
TFT-LCD panel product and manufacturing process technologies of NT$5,553.3 million. The key technology for small and medium-size TFT-LCD production includes the technologies independently developed by Unipac and 13 related patents. The key
technology for large-size TFT-LCD production includes the technologies jointly developed by Unipac and Matsushita, product technologies developed by Unipac and three related patents.



We also recorded NT$11,599.7 million in goodwill. In accordance with U.S. GAAP Statement of Financial Accounting Standards,
or SFAS, No. 141, Business Combinations, goodwill arising from a purchase accounting business combination consummated after June 30, 2001 is not amortized but is tested for impairment. Effective January 1, 2002, for U.S. GAAP purposes,
we adopted SFAS No. 142, Goodwill and Other Intangible Assets. As a result, we test goodwill for impairment on at least an annual basis at the reporting unit level.



Beneficial Conversion Feature of Convertible Bonds



When we issued our convertible bonds in November 2001, ROC GAAP did not
require us to recognize or account for any beneficial conversion feature embedded in the bonds. However, under U.S. GAAP, the beneficial conversion feature should be recognized and measured by allocating a portion of the proceeds equal to the
intrinsic value of that feature to capital surplus. The amount of the beneficial conversion feature was calculated at the commitment date as the difference between the conversion price and the fair value of our shares, multiplied by the number of
shares into which the bonds are convertible. As a result of our allocating a portion of the proceeds equal to the intrinsic value of the beneficial conversion feature to capital surplus for U.S. GAAP purposes, a discount on the bonds was recognized.
The discount resulting from this allocation will be recognized as interest expense over the life of the bonds.



The carrying amount of the convertible bonds was NT$1,206.0 million as of December 31, 2002 and NT$0 as of December 31, 2003 and 2004, and the related
unamortized discount from the beneficial conversion feature was NT$80.9 million as of December 31, 2002 and NT$0 as of December 31, 2003 and 2004. The effective interest rate of the bonds was approximately 6%.

Compensation Costs



Our articles of incorporation require a cash remuneration payment of up to 1% of our annual distributable earnings to our
directors and supervisors. Under ROC GAAP, these payments are charged directly to retained earnings for the period during which our shareholders approve these payments. Under U.S. GAAP, these cash payments have been recorded as compensation expense
in the period when the related services are rendered.



Certain
of our employees are entitled to bonuses in accordance with our articles of incorporation, which specify a bonus amount ranging from 5% to 10% of our annual distributable earnings. Employee bonuses may be paid in cash, shares, or a combination of
both. Under ROC GAAP, these bonuses are appropriated from retained earnings in the period our shareholders approval is obtained. If these employee bonuses are settled through the issuance of our shares, the amount charged against retained
earnings is based on the par value of our shares issued.



Under
U.S. GAAP, the employee bonus expense is charged to income in the year during which services are provided. Shares we issue as part of these bonuses are recorded at fair value. Since the amount and form of the bonuses are not finally determinable
until our shareholders meeting in the following year, the total amount of these bonuses is initially accrued based on the minimum cash value to be paid. Any difference between the amount initially accrued and the fair value of these bonuses
settled by the issuance of our shares is recognized in the year of approval by our shareholders.



Derivative Financial Instruments



We sell our products to customers worldwide and source a significant portion of our raw materials and components from suppliers outside Taiwan. This
exposes us to changes in foreign currency exchange rates. We also have exposure to changes in interest rates that affect our cash flows on long-term borrowings. We use financial instruments, including derivatives such as foreign currency forward
contracts and interest rate swaps, to reduce our foreign currency and interest rate exposure.



For ROC GAAP purposes, we record our interest rate swaps as hedge transactions by recording the net receivable or payable each month related to these interest rate swap contracts, offsetting or adding to our interest
expense of the related debt. For foreign currency forward contracts, we record unrealized gains or losses measured using the change in the spot rate of the contracts in our consolidated statements of operations if the contracts are used to hedge
existing foreign currency denominated receivables and payables, or we defer recognition of unrealized gains or losses for those contracts hedging anticipated transactions that will be denominated in a foreign currency. The discount or premium on a
forward contract is amortized into earnings over the life of the contract.



For U.S. GAAP purposes, we adopted SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended, as of January 1, 2001. In accordance with the related transition provisions of
SFAS No. 133, we recorded an after-tax charge to earnings of NT$0.6 million, representing the cumulative effect of the adoption related to the foreign currency forward contracts for the year ended December 31, 2001. The after-tax earnings
charge to the statements of operations had no material effect on our U.S. GAAP earnings per share for the year ended December 31, 2001.



After our adoption of SFAS No. 133, as amended, none of our existing derivatives met the U.S. GAAP hedge accounting criteria. As a result, all derivative
contracts are recognized as either assets or liabilities and are measured at fair value at each balance sheet date. Changes in fair values of derivative instruments arising subsequent to the transition date amounted to a charge of NT$22.2 million
and NT$(249.6) million in 2003 and 2004, respectively, and are included in other non-operating income for U.S. GAAP purposes. In addition, we reclassified NT$9.4 million and NT$2.8 million, net of tax, of the deferred losses from accumulated other
comprehensive income into earnings from the interest rate swap contracts during 2003 and 2004, respectively. Changes in the fair value of these derivatives in subsequent periods could result in increased volatility of our results of operations under
U.S. GAAP.

Income Taxes



Under ROC GAAP, a valuation allowance is provided on deferred tax assets when they are not certain to be realized based on
the available projection of future taxable income. However, the criteria by which the need for a valuation allowance is determined is less stringent than under U.S. GAAP. Under U.S. GAAP, cumulative losses in recent years are significant piece of
negative evidence, which is difficult to overcome using projections of future taxable income for the purpose of determining the valuation allowance. We suffered losses in 2001 and also had a net loss in the fourth quarter of 2002. As a result, we
did not use the projection of future taxable income in determining our net deferred tax asset valuation allowance for the periods through December 31, 2002. However, we started to generate profits in 2003, and expect to continue to generate profit
going forward. Therefore, more positive evidence is available that the use of available future taxable income projections in determining the size of the valuation allowance is appropriate. As a result, we reversed a valuation allowance of NT$1,869.1
million in 2003.



Under a revised ROC tax rule effective on
January 1, 1998, an additional 10% corporate income tax will be assessed on taxable income but only to the extent such taxable income is not distributed before the end of the following year. As a result, from January 1, 1998 to January 20, 2001, our
undistributed income is subject to a corporate tax rate of 28% and distributed income is taxed at 20%. Commencing from January 20, 2001, the undistributed and distributed income is subject to a corporate tax rate of 32.5% and 25%, respectively.
Under ROC GAAP, the 10% tax on undistributed earnings is recognized as an expense on the date that shareholders approve the amount of the earnings distribution. Under U.S. GAAP, we measure our tax expense, including the tax effects of temporary
differences, using the undistributed rate.



Depreciation
of Property, Plant and Equipment



Under ROC GAAP, we
depreciate buildings over estimated lives of 20 or 50 years based on guidance from the ROC Internal Revenue Code. Under U.S. GAAP, buildings are depreciated over an estimated useful life of 20 years.



Marketable Securities and Equity-Method Investments



Under ROC GAAP, marketable equity securities are carried at the lower of
aggregate cost or market price. Under U.S. GAAP securities that have readily determinable fair values are to be classified as either trading, available-for-sale or held-to-maturity securities. 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. Equity securities not classified as trading securities 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 other comprehensive income. 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. We had no trading or held-to-maturity portfolios as of December 31, 2004. At December 31, 2004, the unrealized loss of one of our available-for-sale securities, which has been in a
continuous unrealized loss position for more than twelve months, amounted to NT$922.9 million. We have determined that the impairment is other than temporary, and as a result, the unrealized loss of NT$922.9 million has been written off to current
operations.



In March 2003, we purchased a 20% ownership in
FDTC, recording the investment at NT$436.3 million, and equity method goodwill of NT$240.2 million. The equity method goodwill will not be amortized in accordance with SFAS No. 142, but will be tested for impairment annually or more frequently if
events or circumstances indicate it might be impaired. Under ROC GAAP, the income and goodwill of FDTC is recognized using the equity method and recorded in the following year. The equity method goodwill will be amortized over five years using the
straight-line method, and the amortization is recorded as investment loss. In August 2004, we sold half of our ownership in FDTC and beginning in September 2004, we recognized income and goodwill of FDTC using the cost method. We sold our remaining
10% ownership in May 2005.

As permitted under ROC GAAP, we recognize our equity in the income (loss) of Patentop in the following
year on a one-year lag basis. Under U.S. GAAP, we recognize our equity in the income (loss) of Patentop in the current year with no lag.



Recent U.S. GAAP Accounting Pronouncements



In November 2004, the FASB issued SFAS No. 151, Inventory Cost. SFAS No. 151 amends the guidance contained in the Accounting Research Bulletin
(ARB) No. 43, Chapter 4, Inventory Pricing, to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs and wasted material (spoilage). This statement is effective for fiscal periods beginning after
June 15, 2005. The initial adoption of SFAS No. 151 is not expected to have a material impact on our results of operations or financial position.



In December 2004, the FASB issued SFAS No. 123 (Revised 2004), Share Based Payment. This statement establishes standards for the accounting of
transactions in which an entity exchanges its equity instruments for goods or services. This statement is effective for fiscal periods beginning after June 15, 2005. On April 14, 2005, the SEC adopted a new rule permitting registrants to elect to
adopt the revised standard beginning of the first annual period that begins after June 15, 2005. We have elected to defer the required adoption until the beginning of the first quarter of 2006. SFAS No. 123R allows for either prospective recognition
of compensation expense or retrospective recognition. We are currently evaluating these transition methods. The initial adoption of SFAS 123R is not expected to have a material impact on our results of operations.



Recent ROC GAAP Accounting Pronouncements



Under ROC GAAP currently in effect, we categorize securities we own as
either short-term investments or long-term investments. Short-term investments are recorded at cost when acquired and stated at the lower of aggregate cost or market value, or LCM. Long-term investments are stated at cost when acquired. Long-term
investments in listed equity securities are evaluated under the LCM method or equity method, depending on the percentage of our shareholdings. Long-term investments in non-listed equity securities are evaluated under the cost method or equity
method, depending on the percentage of our shareholdings. On December 25, 2003, the Financial Accounting Standards Committee, or FASC, issued ROC Statement of Financial Accounting Standards, or ROC SFAS, No. 34, Accounting for Financial
Instruments, which will take effect beginning 2006. Investments in debt and equity securities will be classified into three categories: trading securities, available-for-sale securities and held-to-maturity securities. Changes in the values of
securities in the trading portfolio will be recognized in the income statement immediately; changes in the values of available-for-sale category will be reported as a separate component of shareholders equity; held-to-maturity securities will
be recorded under the amortized cost method.



Under ROC GAAP
currently in effect, derivatives are treated as off-balance sheet items; however, ROC SFAS 34 will require all derivatives to be recorded on the balance sheet at fair value and establish hedge accounting for three different types of
hedges: fair-value hedge, cash-flow hedge and foreign-currency hedge. Under hedge accounting, the effective portion of gains or losses from the hedging instrument and the hedged item will be recognized in earnings immediately. Changes in the fair
value of derivatives that do not meet the criteria of one of these three categories of hedges are recorded directly in earnings. We do not expect the adoption of ROC SFAS No. 34 to have a material effect on our results of operations or financial
condition.



On July 1, 2004, FASC issued ROC SFAS No. 35,
Accounting for Impairment Loss. ROC SFAS No.35 applies to our financial statements for financial periods beginning January 1, 2005. We must recognize impairment loss in respect of our fixed assets, intangible assets, long-term
investments under the equity method,

##### Table of Contents

idle assets and goodwill if their realized value is below their book value. Reversals of impairment losses (except for impairments of goodwill) are
permissible under limited circumstances only. Before ROC SFAS No. 35 came into effect, ROC GAAP did not contain any definitive guidance on the method of recognizing impairment loss. We do not expect the adoption of ROC SFAS No. 35 to have a material
effect on our results of operations or financial condition.



On
December 9, 2004, FASC issued the ROC SFAS No.7 (Revised 2004) Consolidated Financial Statements, which requires us, beginning January 1, 2005, to consolidate in our consolidated financial statements the results of operations of all
entities in which we have control over the financial and operating policies, irrespective of whether or not we have a majority shareholding in such entities. We do not expect the adoption of ROC SFAS No. 7 (Revised 2004) to have a material effect on
our results of operations or financial condition.

Employee salaries are reviewed and adjusted annually, while performance evaluations are conducted
semi-annually. Salaries are adjusted based on inflation and individual performance. As an incentive, discretionary cash bonuses may be paid based on the performance of individuals. In addition, ROC law generally requires that our employees in Taiwan
be given preemptive rights to subscribe for between 10% and 15% of any of our share offerings.



Our employees in Taiwan participate in our profit distributions under our articles of incorporation. Employees in Taiwan are entitled to receive bonus shares, cash or a combination of bonus shares and cash, based on a
percentage of our annual distributable earnings. The amount allocated in shares is, subject to the resolution of our shareholders meeting, determined by valuing the shares at their par value, or NT$10.00 per share, and paid to our employees in
Taiwan based on individual performance and job seniority. We did not allocate any such amount for employees in Taiwan in 2002 for work performed in 2001 due to our net loss in 2001. We paid NT$433.6 million in bonus shares to our employees in 2003
for work performed in 2002. We paid NT$887.9 million in bonus shares and NT$380.5 million (US$12.0 million) in cash bonuses to our employees in 2004 with respect to 2003.



The Hsinchu Science Park Administration offers a variety of employee-related services, including medical examinations,
health insurance, career planning advice and other services for our employees in Taiwan. In addition to the services provided by the Hsinchu Science Park Administration, we have established a welfare committee, a pension fund committee, and other
employee committees and a variety of employee benefit programs.



We do not have an employee option plan as of December 31, 2004. We do not have any collective bargaining arrangement with our employees. We consider our relations with our employees to be good.

United States relating to the manufacturing of TFT-LCD panels. The suit is seeking, among other things, (1) a judgment that the defendants, including us, have directly infringed, contributorily infringed and/or actively induced the infringement of
Sharp Corporations patents; (2) a preliminary and permanent injunction on the infringement of the patents through manufacture, use, import, offer for sale and/or sale of the infringing products and systems; (3) compensatory damages for the
infringed patents, which in any event should not be less than the amount of reasonable royalty had such technology been licensed from Sharp Corporation, together with prejudgment interest, costs and disbursements as determined by the court; and (4)
punitive damages of up to three times the amount found or assessed for infringement of patents due to the willful and deliberate nature of the infringement. On July 6, 2005, we entered into a patent cross license agreement with Sharp Corporation
relating to the patents that are subject to the foregoing litigation. The parties agree that Sharp Corporation will dismiss this lawsuit against us.



On April 13, 2004, Commissariat A LEnergie Atomique, a French government agency, filed a lawsuit against us, our U.S. subsidiary and sixteen other

On January 19, 2005, Guardian Industries Corp. filed a suit in the United States District Court for the District of Delaware against us and twenty other co-defendants, including BenQ, alleging infringement of certain

On February 24, 2005, Thomson Licensing S.A. and Thomson Licensing Inc. filed an action with the United States International Trade Commission against us and BenQ, alleging infringement of certain U.S. patents through the importation and
sale in the U.S. of certain color TV receivers, color display monitors and components thereof (accused products). The action seeks, among other things, (1) the commencement of an investigation by the International Trade Commission to
remedy the unlawful importation in the U.S., the sale for importation into the U.S. and/or the sale within the U.S. after importation by BenQ of the accused products; (2) the issuance of a permanent exclusion order excluding from entry into the U.S.
all accused products manufactured by or for BenQ, that infringe one or more of the patents; and (3) a cease and desist order directing BenQ to immediately cease the importation into the U.S., sale for importation in the U.S. and sale in the U.S.
after importation of the accused products and to immediately cease the demonstration, sale, use and movement or shipment of U.S. inventory of the accused products. On March 9, 2005, Thomson Licensing S.A. also filed a suit in the United States
District Court for the Northern District of California against us and BenQ, alleging infringement of the same patents that are the subject of the action filed with the International Trade Commission. The lawsuit filed in California has been
automatically stayed pending the outcome of the action filed with the International Trade Commission. As of the date of this report it is not possible to predict the outcome or likely outcome of the litigation, or the total costs of resolving the
litigation.



Our customers may from time to time be subject to
lawsuits related to products that contain TFT-LCD panels manufactured by us. Two such lawsuits initiated by Sharp against BenQ and TECO Electric and Machinery Co. are currently pending in Japan. On July 6, 2005, we entered into a patent cross
license agreement with Sharp Corporation. The parties agree that Sharp Corporation will dismiss the lawsuit against BenQ pending in Japan.

In addition to permitting dividends to be paid out of accumulated earnings after deducting losses, we are permitted under
the ROC Company Law to make distributions to our shareholders of additional shares by capitalizing reserves, including the legal reserve. However, the capitalized portion payable out of our legal reserve is limited to 50% of the total accumulated
legal reserve, and only if and to the extent the accumulated legal reserve exceeds 50% of our paid-in capital. See Item 10. Additional InformationArticles of IncorporationDividends and Distributions. For information as to ROC
taxes on dividends and distributions, see Item 10. TaxationROC Tax ConsiderationsDividends.



The holders of ADSs will be entitled to receive dividends to the same extent as the holders of our shares, subject to the terms of the deposit agreement.



Any cash dividends will be paid to the depositary in NT
dollars and, after deduction of any applicable ROC taxes and fees and expenses of the depositary and custodian, except as otherwise provided in the deposit agreement, will be converted by the depositary into U.S. dollars and paid to the holders of
ADSs. Whenever the depositary receives any free distribution of shares, including stock dividends, on any ADSs that the holders of ADSs hold, the depositary may, and will if we so instruct, deliver to the holders of ADSs additional ADSs which
represent the number of shares received in the free distribution, after deduction of applicable taxes and the fees and expenses of the depositary and the custodian. If additional ADSs are not so delivered, each ADS that the holders of ADSs hold
shall represent its proportionate interest in the additional shares distributed.

10.B. Articles of Incorporation



The following statements summarize the material elements of our capital structure and the more important rights and privileges of our shareholders conferred by ROC law and our Articles of Incorporation.



Objects and Purpose



The scope of our business as set forth in Article 2 of our articles of incorporation includes the research, development,
production, manufacture and sale of the following products: plasma display and related systems, liquid crystal display and related systems, OLED and related systems, amorphous silicon photo sensor device parts and components, thin film photo diode
sensor device parts and components, thin film transistor photo sensor device parts and components, touch imaging sensors, full color active-matrix flat panel displays, field emission displays, single crystal liquid crystal displays, original
equipment manufacturing for amorphous silicon thin film transistor process and flat panel display modules, original design manufacturing and original equipment manufacturing business for flat panel display modules and the simultaneous operation of a
trade business relating to our business.



Directors



Our board of directors is elected by our shareholders and is responsible for
the management of our business. Our articles of incorporation provide that our board of directors is to have between seven to nine members. Currently, our board of directors is composed of nine directors. The chairman of our board is elected by the
directors. The chairman presides at all meetings of our board of directors, and also has the authority to represent our company. The term of office for our directors is three years.



As required under our articles of incorporation, we currently have three supervisors. In accordance with the ROC Company
Law, supervisors are elected by our shareholders and cannot concurrently serve as our directors, executive officers or other staff members. The term of office for supervisors is three years. The supervisors duties and powers include, but are
not limited to, investigation of our financial condition, inspection of corporate records, verification of statements by the board of directors, giving reports at shareholders meetings, representation of us in negotiations with our directors
and giving notification, when appropriate, to the board of directors to cease acting in contravention of applicable law or regulations or our articles of incorporation or beyond our scope of business.



The election of our directors and supervisors by our shareholders may be
conducted by means of cumulative voting or other voting mechanics, if any, adopted in our articles of incorporation. Pursuant to the ROC Company

##### Table of Contents

Law, the election of our directors and supervisors is currently conducted by means of cumulative voting, as our articles of incorporation do not provide for
another voting mechanism. The most recent election for all of the directors and supervisors was held on April 29, 2004.



Pursuant to the ROC Company Law, a person may serve as a director or supervisor in his or her personal capacity or as the representative of another legal
entity. A legal entity that owns our shares may be elected as a director or supervisor, in which case a natural person must be designated to act as the legal entitys representative. A legal entity that is our shareholder may designate its
representative to be elected as our director or supervisor on its behalf. In the event several representatives are designated by the same legal entity, any or all of them may be elected. A natural person who serves as the representative of a legal
entity as a director or supervisor may be removed or replaced at any time at the discretion of such legal entity, and the replacement director or supervisor may serve the remainder of the term of office of the replaced director or supervisor.
Currently, four of our directors and two of our supervisors are representatives of other legal entities, as shown in Item 6.Directors, Senior Management and EmployeesDirectors and Senior ManagementExecutive Officers.



Shares



As of July 1, 2005, our authorized share capital was NT$70 billion, divided into seven billion common shares, of which 100
million shares are reserved for the issuance of shares for employee stock options, and 4,958,040,897 shares were issued.



On June 2, 2004, we issued 305,803,656 shares of common stock for purposes of distributing stock dividends and employee bonuses. On June 23, 2004, we
issued 300 million shares of our common stock in the form of 30 million ADSs. Each ADS represents the right to receive 10 shares of common stock. The public offer price per ADS was US$16.00. On June 14, 2005, our shareholders approved the issuance
of 542,506,235 common shares for purposes of distributing stock dividends and employee stock bonuses. The stock issuance was authorized by the government authorities. The record date for this stock issuance is July 20, 2005.



All shares presently issued, including those underlying our ADSs, are fully
paid and in registered form, and existing shareholders are not obligated to contribute additional capital.



New Shares and Preemptive Rights



The issuance of new shares requires 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, which requires approval of our shareholders in a shareholders meeting. We must also obtain the approval of, or submit a registration to, the ROC Financial and Supervisory Commission and the Hsinchu Science Park
Administration Bureau, as applicable. Generally, when a company issues capital stock for cash, 10% to 15% of the issue must be offered to its employees. In addition, if a public company intends to offer new shares for cash, at least 10% of the issue
must also be offered to the public. 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.



Register of Shareholders and Record Date



Our share registrar, SinoPac Securities Corporation, maintains the register
of our shareholders at its office in Taipei, Taiwan, and enters transfers of our shares in the register upon presentation of, among other documents,



70



---

##### Table of Contents

the certificates in respect of our shares transferred. The ROC Company Law permits us, by giving advance public notice, to set a record date and close the
register of shareholders for a specified period in order to determine the shareholders or pledgees that are entitled to certain rights pertaining to our shares. Under the ROC Company Law, our register of shareholders should be closed for a period of
sixty days before each ordinary meeting of shareholders, thirty days before each extraordinary meeting of shareholders and five days before each record date.



Transfer of Shares



Under the ROC Company Law, shares are transferred by endorsement and delivery of the related share certificates. In addition, transferees must have their
names and addresses registered on our register in order to assert shareholders rights against us. Notwithstanding the foregoing, shareholders are required to file their specimen seals with our share registrar. The settlement of trading of our
shares on the Taiwan Stock Exchange will be carried out on the book-entry system maintained by Taiwan Securities Central Depository Co., Ltd.



Shareholders Meetings



We are required to hold an annual ordinary shareholders meeting once every calendar year, generally within six months after the end of each fiscal
year. Any shareholder who holds 1% or more of our issued and outstanding common shares may submit one written proposal for discussion at our annual ordinary shareholders meeting. Our directors may convene an extraordinary shareholders meeting
whenever they 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 their shares for more than a year. In addition, any of our supervisors may convene a
shareholders meeting under certain circumstances. For a public company in Taiwan, such as our company, 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 and voting. A distribution of cash dividends would be an example of an act requiring an ordinary resolution. A special resolution may be adopted in a meeting of shareholders convened with a quorum of holders of at least two-thirds of
our total outstanding shares at which the holders of at least a majority of our shares represented at the meeting vote in favor thereof. A special resolution is necessary for various matters under ROC law, including:



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



| |  |  | our dissolution or amalgamation;
| | - |  | --------------------------------



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



| |  |  | transfers of the whole or a substantial part of our business or properties;
| | - |  | ---------------------------------------------------------------------------



| |  |  | the acquisition of the entire business of another company which would have a significant impact on our operations;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | the distribution of any stock dividend; or
| | - |  | ------------------------------------------



| |  |  | the removal of directors or supervisors.
| | - |  | ----------------------------------------



However, in the case of a public company such as our company, a special resolution may be adopted by holders of at least two-thirds of the shares
represented at a meeting of shareholders at which holders of at least a majority of the total outstanding shares are present.



Voting Rights



According to the ROC Company Law, a holder of our shares has one vote for each share held at shareholders meetings. However, (i) treasury shares or
(ii) our common shares held by an entity in which our company owns more than 50% of the voting shares or paid-in capital, or Controlled Entity, or by a third entity in



71



---

##### Table of Contents

which our company and a Controlled Entity jointly own, directly or indirectly, more than 50% of the voting shares or paid-in capital cannot be voted. There
is cumulative voting for the election of directors and supervisors. In all other matters, shareholders must cast all their votes the same way on any resolution. Voting rights attached to our common shares may be exercised by personal attendance or
proxy, or at our discretion, by written or electronic ballot.



If any shareholder is represented at an ordinary or extraordinary shareholders meeting by proxy, a valid proxy form must be delivered to us five days before the commencement of the ordinary or extraordinary shareholders meeting.
Voting rights attached to our shares that are exercised by our shareholders proxy are subject to ROC proxy regulations. 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, is not permitted to vote or exercise voting rights nor vote or exercise voting rights on behalf of another shareholder on such matter.



Except for trust enterprises or share transfer agents approved by the ROC Financial and Supervisory Commission, where one
person is appointed as proxy by two or more shareholders who together hold more than 3% of our shares, the votes of those shareholders in excess of 3% of our total issued shares will not be counted.



You will not be able to exercise voting rights on the shares underlying your
ADSs on an individual basis.



Dividends and Distributions



We may distribute dividends in any year in which we have accumulated
earnings. Before distributing a dividend to shareholders following the end of a fiscal year, we must recover any past losses, pay all outstanding taxes, and set aside in a legal reserve 10% of our annual earnings for that fiscal year until our legal
reserve equals our paid-in capital.



At the shareholders
annual ordinary meeting, our board of directors submits to the shareholders for approval proposals for the distribution of a dividend or the making of any other distribution to shareholders from our accumulated earnings or reserves for the preceding
fiscal year. Dividends may be distributed either in cash, in the form of shares or a combination of cash and shares. Our articles of incorporation provide that the cash portion of any dividend shall generally not be less than 10% of the annual
dividend. However, the ratio for cash dividends may be adjusted in accordance with actual earnings and operating conditions. Dividends are paid proportionately to shareholders as listed on the register of shareholders on the relevant record date.



Our articles of incorporation provide that we shall allocate
10% of our annual earnings as a legal reserve in each fiscal year after:



| |  |  | payment of all income taxes; and
| | - |  | --------------------------------



| |  |  | deduction of any past losses.
| | - |  | -----------------------------



Earnings distributions are made in the following manner:



| |  |  | 5% to 10% of the remainder is distributable as a bonus for employees;
| | - |  | ---------------------------------------------------------------------



| |  |  | no more than 1% of the remainder is distributable as remuneration to directors and supervisors; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | all or a portion of the balance is distributable as a dividend and bonus to our shareholders.
| | - |  | ---------------------------------------------------------------------------------------------



In addition to permitting dividends to be paid out of accumulated earnings after deducting losses, we are permitted under
the ROC Company Law to make distributions to our shareholders of additional shares by capitalizing reserves, including the legal reserve. However, the capitalized portion payable out of our legal reserve is limited to 50% of the total accumulated
legal reserve, and only if and to the extent the accumulated legal reserve exceeds 50% of our paid-in capital.



For information on the dividends paid by us in recent years, see Item 8. Financial InformationDividends and Dividend Policy. For
information as to ROC taxes on dividends and distributions, see Item 10.Additional InformationTaxationROC Tax ConsiderationsDividends.

Acquisition of Shares by Our Company



With limited exceptions under the ROC Company Law, we are not permitted to acquire our shares.



In addition, pursuant to 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 our shares on the Taiwan Stock Exchange or by a tender offer, in accordance with the procedures prescribed by the ROC Financial and Supervisory
Commission, for the following purposes:



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



| |  |  | to facilitate conversion arising from bonds with warrants, preferred shares with warrants, convertible bonds, convertible preferred shares or certificates of warrants issued by our
company into shares; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



We are not allowed to purchase more than 10% of our aggregate issued and
outstanding shares. In addition, we may not spend more than the aggregate amount of our 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 or through a tender offer, our affiliates, directors, supervisors, officers 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.



According to the ROC Company Law, as last amended and effective from June 24, 2005, an entity in which our company directly or indirectly owns more than
50% of the voting shares or paid-in capital, which is referred to as a controlled entity, may not purchase our shares. Also, if our company and a controlled entity jointly own, directly or indirectly, more than 50% of the voting shares or paid-in
capital of another entity, which is referred to as a third entity, the third entity may not purchase shares in either our company or a controlled entity.



On October 14, 2002, our board of directors approved a buyback program for market repurchases of up to 10 million shares during the period between October
15, 2002 and December 14, 2002 at the target purchase price of between NT$15 and NT$20 per share, with a view to transferring these shares to our employees. We did not make any repurchases under this buyback program. On December 16, 2002, our board
of directors approved another buyback program for market repurchases of up to 20 million shares during the period between December 17, 2002 and February 16, 2003 at the target price of between NT$17.5 and NT$23.5 per share for the same purpose. We
repurchased an aggregate of 12 million shares at an average purchase price of NT$20.9 per share, or an aggregate purchase price of NT$250.8 million, under this buyback program.



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 Law.



Rights to Bring Shareholder Suits



Under the ROC Company Law, a shareholder may bring suit against us in the following events:



| |  |  | Within 30 days from the date on which a shareholders resolution is adopted, a shareholder may file a lawsuit to annul a shareholders resolution if the procedure for
convening a shareholders meeting or the method of resolution violates any law or regulation or our articles of incorporation.

| |  |  | If the substance of a resolution adopted at a shareholders meeting contradicts any applicable law or regulation or our articles of incorporation, a shareholder may bring a
suit to determine the validity of such resolution.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Shareholders may bring suit against our directors and supervisors under the following circumstances:



| |  |  | Shareholders who have continuously held 3% or more of the total number of issued and outstanding shares for a period of one year or longer may request in writing that a supervisor
institute an action against a director on our behalf. In case the supervisor fails to institute an action within 30 days after receiving such request, the shareholders may institute an action on our behalf. In the event that shareholders institute
an action, a court may, upon motion of the defendant, order such shareholders to furnish appropriate security.

| |  |  | In the event that any director, supervisor, officer or shareholder who holds more than 10% of our issued and outstanding shares and their respective spouse and minor children and/or
nominees sells shares within six months after the acquisition of such shares, or repurchases the shares within six months after the sale, we may make a claim for recovery of any profits realized from the sale and purchase. If our board of directors
or our supervisors fail to make a claim for recovery, any shareholder may request that our board of directors or our supervisors exercise the right of claim within 30 days. In the event our directors or our supervisors fail to exercise such right
during such 30-day period, such requesting shareholder will have the right to make a claim for such recovery on our behalf. Our directors and supervisors will be jointly and severally liable for damages suffered by us as a result of their failure to
exercise the right of claim.

Financial Statements



For a period of at least ten days before our annual
shareholders meeting, we must make available our annual financial statements at our principal offices in Hsinchu, Taiwan and our share register in Taipei, for inspection by our shareholders.



Transfer Restrictions



Our directors, supervisors, officers and shareholders holding more than 10% of our issued and outstanding shares and their
respective spouse and minor children and/or nominees, which we refer to as insiders, are required to report any changes in their shareholding to us on a monthly basis. No insider is permitted to sell shares on the Taiwan Stock Exchange for six
months from the date on which the relevant person becomes an insider. In addition, the number of shares that insiders can sell or transfer on the Taiwan Stock Exchange on a daily basis is limited by ROC law. Furthermore, insiders may sell or
transfer our shares on the Taiwan Stock Exchange only after reporting to the ROC Financial and Supervisory Commission at least three days before the transfer, provided that such reporting is not required if the number of shares transferred does not
exceed 10,000.



Other Rights of Shareholders



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



Transfer Agent and Registrar



The transfer agent and registrar for our shares is SinoPac Securities
Corporation, 3rd Floor, 53, Po Ai Road, Taipei, Taiwan; telephone number: 886-2-2381-6288. The transfer agent and registrar for our ADS is Citibank, N.A., 388 Greenwich Street, 14thFloor, New York, New York, 10013, USA; telephone number: 1-877-248-4237.

10.C. Material Contracts



License from Matsushita. Unipac entered into a five-year Technology Assistance and Patent License Agreement with Matsushita effective as of October 30, 1998, which provides for the non-transferable and non-exclusive license and
technical support to manufacture TFT-LCD panels between 13.3 inches and 19.0 inches at our previous second-generation fab and our 3.5-generation fab. The agreement provides for a fixed license fee, and, subject to a maximum payment requirement,
ongoing royalty payments at a percentage of the sales of the panels we manufacture using the licensed technology. Currently, we pay royalties for production of 13.3-inch and 14.1-inch TFT-LCD panels manufactured at one of our 3.5-generation fabs.
This agreement expired on October 31, 2003, and we are entitled to a grace period of three years during which we can continue using the license while proceeding with negotiation efforts for license renewal.



License from FDTC. We have a license agreement with FDTC, effective as
of March 31, 2003, which provides for the non-transferable and non-exclusive license and technical support to manufacture all of our TFT-LCD panels at each of our facilities. The agreement provides for an initial license fee and fixed royalty
payments to be paid for each of the first four consecutive 12-month periods following the effective date of the agreement.



Licenses from SEL. We entered into a license agreement with SEL effective as of September 1, 2003 in connection with our settlement and mutual
release relating to a suit brought by SEL. The license agreement provides for the non-transferable and non-exclusive license to manufacture all of our amorphous silicon TFT-LCD panels and modules at each of our facilities using intellectual property
owned by SEL. The agreement provides for a fixed license fee and ongoing royalty payments at a percentage of the sales of the panels we manufacture using the licensed technology.



10.D. Exchange Controls



We
have extracted from publicly available documents the information presented in this section. Please note that citizens of the PRC and entities organized in the PRC are subject to special ROC laws, rules and regulations, which are not discussed in
this section.



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



Aside from trade-related foreign
exchange transactions, Taiwan companies and residents may remit to and from Taiwan foreign currencies of up to US$50 million and US$5 million, respectively, each calendar year. A requirement is also imposed on all private enterprises to report all
medium- and long-term foreign debt with the Central Bank of China.



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



10.E. Taxation



ROC Tax Considerations



The following summarizes the principal ROC tax
consequences of owning and disposing of ADSs and shares if you are not a resident of Taiwan. You will be considered a non-resident of Taiwan for the purposes of this section if:



| |  |  | you are an individual and you are not physically present in Taiwan for 183 days or more during any calendar year; or
| | - |  | --------------------------------------------------------------------------------------------------------------------



75



---

##### Table of Contents

| |  |  | you are an entity and you are organized under the laws of a jurisdiction other than Taiwan and have no fixed place of business or other permanent establishment in Taiwan.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



You should consult your own tax advisors
concerning the tax consequences of owning ADSs or shares in Taiwan and any other relevant taxing jurisdiction to which you are subject.



Dividends



Dividends, whether in cash or shares, declared by us out of retained earnings and paid out to a holder that is not a Taiwan resident in respect of shares
represented by ADSs or shares are subject to ROC withholding tax. The current rate of withholding for non-residents is 20% of the amount of the distribution, in the case of cash dividends, or of the par value of the shares distributed, in the case
of stock dividends. As discussed below in Retained Earnings Tax, our after-tax earnings will be subject to an undistributed retained earnings tax. To the extent dividends are paid out of retained earnings that have been subject to the
retained earnings tax, the amount of such tax will be used by us to offset the withholding tax liability on such dividend. Consequently, the effective rate of withholding on dividends paid out of retained earnings previously subject to the retained
earnings tax will be less than 20%. There is no withholding tax with respect to stock dividends declared out of our capital reserves.



Capital Gains



Gains realized on ROC securities transactions inside or outside of Taiwan are currently exempt from ROC income tax. In addition, sales of ADSs by
non-resident holders are not regarded as sales of ROC securities and, as a result, any gains on such transactions are currently not subject to ROC income tax.



Securities Transaction Tax



The ROC government imposes a securities transaction tax that will apply to sales of shares, but not to sales of ADSs. The transaction tax is payable by
the seller for the sale of shares and is equal to 0.3% of the sales proceeds.



Estate and Gift Tax



ROC estate tax is payable on any property within the ROC of a deceased individual, and ROC gift tax is payable on any property within the ROC donated by any 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, shares issued by ROC companies, such as our shares, are
deemed located in the ROC regardless of the location of the holder. It is unclear whether or not ADSs will be deemed assets located in the ROC for the purpose of ROC gift and estate taxes.



Preemptive Rights



Distributions of statutory preemptive rights for shares in compliance with
the ROC Company Law are not subject to ROC tax. Proceeds derived from sales of statutory preemptive rights evidenced by securities by a non-resident are exempt from income tax, but may be subject to an ROC securities transaction tax, discussed
above. Proceeds derived from sales of statutory preemptive rights that are not evidenced by securities are subject to income tax at the rate of:



| |  |  | 25% of the gains realized by non-Taiwan entities; and
| | - |  | -----------------------------------------------------



| |  |  | 35% of the gains realized by non-Taiwan individuals.
| | - |  | ----------------------------------------------------



We have the sole discretion to determine whether statutory preemptive rights are evidenced by securities or not.

##### Table of Contents

Retained Earnings Tax



Under the ROC Income Tax Laws, we are subject to a 10% retained earnings tax on our after-tax earnings generated after
January 1, 1998 that are not distributed in the following year. Any retained earnings tax so paid will further reduce the retained earnings available for future distribution. When we declare dividends out of those retained earnings, a maximum amount
of up to 10% of the declared dividends will be credited against the 20% withholding tax imposed on the non-resident holders of our ADS or shares.



Tax Treaty



Taiwan does not have an income tax treaty with the United States. Taiwan has tax treaties for the avoidance of double taxation with Indonesia, Singapore,
South Africa, Australia, Netherlands, Vietnam, New Zealand, Malaysia, Macedonia, Swaziland, Gambia, United Kingdom, Senegal and Sweden, which may limit the rate of ROC withholding tax on dividends paid with respect to shares. It is unclear whether,
if you hold ADSs, you will be considered to hold shares for the purposes of these treaties. Accordingly, if you may otherwise be entitled to the benefits of an income tax treaty, you should consult your tax advisors concerning your eligibility for
the benefits with respect to ADSs.



United States Federal Income Tax
Considerations for United States Holders



The following is
a discussion of the material U.S. federal income tax consequences of the purchase, ownership and disposition of our ADSs or shares to the U.S. Holders described in this annual report. The discussion set forth below applies only to beneficial owners
of our ADSs or shares that are U.S. Holders, hold the ADSs or shares as capital assets and are non-residents of Taiwan as defined under ROC Tax Considerations. You are a U.S. Holder if, for United States federal income tax
purposes, you are:



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



| |  |  | a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any political subdivision thereof; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



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



This summary is based on the Internal Revenue Code of 1986, as amended, (the
Code), administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as currently in effect. These laws are subject to change, possibly on a retroactive basis. In addition, this summary is
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 contain 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 describe the U.S. federal income tax consequences applicable to U.S. Holders subject to special treatment under the U.S. federal income tax laws, such as:



| |  |  | dealers and traders in securities or foreign currencies;
| | - |  | --------------------------------------------------------



| |  |  | certain financial institutions;

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



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



| |  |  | persons holding ADSs or shares as part of a hedge, straddle, conversion transaction, or other integrated transaction;

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



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



You are urged to consult your tax advisor concerning the particular United
States federal income tax consequences to you of the purchase, ownership and disposition of ADSs or shares, as well as the consequences to you arising under the laws of any other taxing jurisdiction.



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 applicable to dividends received by certain non-corporate U.S. 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 U.S. Holders, each
described below, could be affected by actions that may be taken by parties to whom the ADSs are pre-released.



For U.S. federal income tax purposes, a U.S. Holder who is the beneficial owner of an ADS will generally be treated as the owner of the shares underlying
the ADS.



This discussion assumes that we were not a passive
foreign investment company for our 2004 taxable year, as discussed below.



Taxation of Dividends



Distributions you receive on your ADSs or shares, other than certain pro rata distributions of shares, including amounts withheld in respect of ROC withholding taxes, will generally be treated as dividend income to you to the extent the
distributions are made from our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). The amount of a dividend will include any amounts withheld by us or our paying agent in respect of ROC taxes
(reduced by any credit against such withholding tax as a result of the 10% retained earnings tax previously paid by us). The amount will be treated as foreign source dividend income to you and will not be eligible for the dividends-received
deduction generally allowed to U.S. corporations under the Code.



Dividends paid in New Taiwan dollars will be included in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date of your (or, in the case of ADSs, the depositarys) receipt of the
dividend, regardless of whether the payment is in fact converted into U.S. dollars. If the dividend is converted into U.S. dollars on the date of receipt, you generally should not be required to recognize foreign currency gain or loss in respect of
the dividend income. You may have foreign currency gain or loss, which will be U.S. source, if you do not convert the amount of such dividend into U.S. dollars on the date of receipt.



Subject to limitations that may vary depending upon your circumstances and the concerns expressed by the U.S. Treasury
described above, you may be entitled to a credit against your U.S. federal income taxes for the amount of any ROC taxes that are withheld from dividend distributions made to you. In determining the amounts withheld in respect of ROC taxes, any
reduction of the amount withheld on account of an 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 liability. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. The rules governing

##### Table of Contents

the foreign tax credit are complex. We therefore urge you to consult your own tax advisor regarding the availability of the foreign tax credit under your
particular circumstances. Instead of claiming a credit, you may, at your election, deduct otherwise creditable ROC taxes in computing your taxable income, subject to generally applicable limitations.



Subject to applicable limitations that may vary depending upon a U.S.
Holders individual circumstances, dividends paid to certain non-corporate U.S. Holders of our ADSs in taxable years beginning before January 1, 2009 will be taxable at a maximum tax rate of 15%. Non-corporate U.S. Holders of ADSs should
consult their own tax advisors to determine whether they are subject to any special rules that limit their ability to be taxed at this favorable rate.



It is possible that pro rata distributions of shares to all shareholders may be made in a manner that is not subject to U.S. federal income tax, but is
subject to ROC withholding tax as discussed above under ROC Tax ConsiderationsDividends. Such distribution will not give rise to U.S. federal income tax against which the ROC withholding tax imposed on these distributions may be
credited. Accordingly, you may not be able to credit such ROC tax against your U.S. federal income tax liability unless you have other foreign source income in the appropriate foreign tax credit class of income. The basis of any new ADSs or shares
you receive as a result of a pro rata distribution of shares by us will be determined by allocating your basis in the old ADSs or shares between the old ADSs or shares and the new ADSs or shares received, based on their relative fair market values
on the date of distribution.



Taxation of Capital Gains



For U.S. federal income tax purposes, when you sell
or otherwise dispose of your ADSs or shares, you will recognize U.S. source capital gain or loss in an amount equal to the difference between the U.S. dollar value of the amount realized for the ADSs or shares and your adjusted tax basis in the ADSs
or shares, determined in U.S. dollars. Any such gain or loss will be long-term capital gain or loss if you held the ADSs or shares for more than one year. Your ability to deduct capital losses is subject to limitations.



Passive Foreign Investment Company Rules



We believe that we were not a passive foreign investment
company, or PFIC, for U.S. federal income tax purposes for our 2004 taxable year. However, since PFIC status depends upon the composition of our income and assets and the market value of our assets (including, among others, goodwill) from time
to time, there can be no assurance that we will not be considered a PFIC for any taxable year. If we were treated as a PFIC for any taxable year during which you held ADSs or shares, certain adverse tax consequences could apply to you.



If we are treated as a PFIC for any taxable year during which you held
ADSs or shares, gain recognized by you on a sale or other disposition of ADSs or shares would be allocated ratably over your holding period for the ADSs or shares. The amounts allocated to the taxable year of the sale or other exchange and to any
year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, and an interest charge would be
imposed on the amount allocated to such taxable year. Further, any distribution in respect of ADSs or shares in excess of 125% of the average of the annual distributions on ADSs or shares received by you during the preceding three years or your
holding period, whichever is shorter, would be subject to taxation as described above. Certain elections may be available (including a mark-to-market election) to U.S. Holders that may mitigate the adverse tax consequences described above.



In addition, if we were to be treated as a PFIC in a taxable
year in which we pay a dividend or the prior taxable year, the 15% dividend rate discussed above with respect to dividends paid to certain non-corporate U.S. Holders of ADSs would not apply.

Information Reporting and Backup Withholding



Payments of dividends and sales proceeds that are made within the United
States or through certain U.S.-related financial intermediaries generally are subject to information reporting and to backup withholding unless (i) you are a corporation or other exempt recipient or (ii) in the case of backup withholding, you
provide a correct taxpayer identification number and certify that you are not subject to backup withholding.



The amount of any backup withholding from a payment to you will be allowed as a credit against your U.S. federal income tax liability and may entitle you
to a refund, provided that the required information is timely furnished to the Internal Revenue Service.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



Market Risks



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 ordinary course of business.



We use financial instruments, including variable rate debt and swap and foreign currency forward contracts, to finance our operations and to manage risks associated with our interest rate and foreign currency exposures, through a controlled
program of risk management in accordance with established policies. We have used, and intend to continue to use, derivative financial instruments only for hedging purposes. These policies are reviewed and approved by our board of directors. Our
treasury operations are subject to the review of our internal audit department, which review is submitted for our supervisors review on a quarterly basis.



As of December 31, 2004, we had U.S. dollar- and Japanese yen-denominated savings accounts of US$24.7 million and ¥3,638.2 million, respectively.
We also had certificates of deposit denominated in U.S. dollars and Japanese yen in the amount of US$72.0 million and ¥12,210.5 million, respectively. Since export sales are primarily conducted in U.S. dollars, we had U.S. dollar-denominated
accounts receivable of US$649.8 million as of December 31, 2004, which represents 96.4% of the total accounts receivable balance at that date. We also had Japanese yen-denominated accounts receivable of ¥1,047.0 million attributable to our
Japanese operations as of December 31, 2004, which represents 1.5% of the total accounts receivable balance at that date. In addition, we had U.S. dollar- and Japanese yen-denominated accounts payable of US$525.5 million and ¥22,621.9 million,
respectively, relating to our overseas vendors.

movements on foreign currency-denominated accounts receivable and capital expenditures relating to equipment used in our manufacturing processes and purchased primarily from Japan. The fair value of forward exchange contracts and interest rate swaps
has been determined by obtaining from our bankers the estimated amount that would be received/(paid) to terminate the contracts.



Interest Rate Risk



Our exposure to market risk for changes in interest rates relates primarily to our long-term debt obligations. We incur debt obligations primarily to
support general corporate purposes, including capital expenditures and working capital needs. We use interest rate swaps to modify our exposure to interest rate movements and reduce borrowing costs. Interest rate swaps limit the risks of fluctuating
interest rates by allowing us to convert a portion of the interest on our borrowings from a variable rate to a fixed rate.



As of December 31, 2004, we had 38 outstanding interest rate swap agreements with eight major international financial institutions, having a total
notional principal amount of NT$24,500 million.



The table
below provides information about our derivative financial instruments and other financial instruments that are sensitive to changes in interest rates, including interest rate swaps, debt obligations and certain assets. For debt obligations, the
table sets forth principal cash flows and related weighted average interest rates by expected maturity date. For interest rate swaps, the table presents notional amounts and weighted average interest rates by contractual maturity date. Notional
amounts are used to calculate the contractual payments to be exchanged under a contract. Weighted average variable rates are based on implied forward rates in the production yield curve at the reporting date. The information is presented in the
currencies in which the instruments are denominated. We do not have any capital lease obligations.

Foreign Currency Risk



The primary foreign currencies to which we are exposed are the Japanese yen and the U.S. dollar. We enter into short-term
forward exchange contracts to hedge the impact of foreign currency fluctuations on certain

##### Table of Contents

underlying assets, liabilities, and firm commitments for the purchase of raw materials and components and capital expenditures denominated in U.S. dollars.
The purpose of entering into these hedges is to minimize the impact of foreign currency fluctuations on the results of operations. Gains and losses on foreign currency contracts and foreign currency denominated liabilities are recorded in the period
of the exchange rate changes, while gain and loss on foreign currency contracts that hedge foreign currency commitments are deferred until the commitments are realized. The contracts have maturity dates that do not exceed three months.



The table below sets forth our outstanding foreign currency forward
contracts as of December 31, 2004:

ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT



Our board of directors has determined that Vivien Huey-Juan Hsieh is an audit committee financial expert, as that term is defined in Item 16A(b) of Form 20-F.



ITEM 16B. CODE OF ETHICS



Our
employee handbook, which applies to all officers and employees, contains provisions covering conflicts of interest, corporate opportunities, confidentiality, fair dealing, protection and proper use of company assets and encouraging the reporting of
any illegal or unethical behavior. Although, we have not adopted a written code of ethics specifically for our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar
functions, the provisions in our employee handbook cover these individuals and there have not been any waivers of the provisions of the employee handbook for any officers or employees. Ethical oversight and actual or apparent conflicts of interest
have historically been handled informally by senior management, the board of directors and supervisors. We will continue to address violations of the code of business conduct and ethics contained in our employee handbook and will continue to
consider a separate code of ethics with the board of directors should the need arise.



ITEM 16C. PRINCIPAL ACCOUNTANT FEES AND SERVICES



Duration of the Mandate and Terms of Office of the Independent Registered Public Accounting Firm



KPMG, our independent registered public accounting firm, began serving as our auditor upon the formation of our company in 2001. The head auditors
currently responsible for our audit are Mei-Yu Tseng and Kuen-Huei Chen. Mr. Chen has been serving in his role since the incorporation of AU Optronics. Ms. Tseng has been serving in her role since the second quarter of 2004, when she took over for
Shing Hai Wei who had until then served as our head auditor since our incorporation.



Policy on Pre-Approval of Audit and Non-Audit Services of Independent Registered Public Accounting Firm



Our audit committee is responsible for the oversight of KPMGs work. The policy of our audit committee is to pre-approve all audit and non-audit
services provided by KPMG, including audit services, audit-related services, tax services and other services, as described below. The audit committee sets forth its pre-approval in detail, listing the particular services or categories of services
which are pre-approved, and setting forth a specific budget for such services. In urgent circumstances, the audit committees chairman may issue such a pre-approval. Additional services may be pre-approved on an individual basis. KPMG and our
management then report to the audit committee on a quarterly basis regarding the extent of services actually provided in accordance with the applicable pre-approval, and regarding the fees for the services performed.



Auditor Fees



We paid the following fees for professional services to KPMG for the years ended December 31, 2003 and 2004.

Report of Independent Registered Public Accounting Firm



The Board of Directors and Stockholders

AU Optronics Corp.:



We have audited the consolidated balance sheets of AU Optronics Corp. and subsidiaries as of December 31, 2003 and 2004, and the related consolidated
statements of operations, stockholders equity and cash flows for each of the years in the three-year period ended December 31, 2004. 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 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
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 in the first paragraph present fairly, in all material respects, the financial position of AU Optronics Corp. and subsidiaries as of December 31, 2003 and 2004, and the results of their operations and their cash
flows for each of the years in the three-year period ended December 31, 2004, in conformity with accounting principles generally accepted in the Republic of China.



The consolidated financial statements as of and for the year ended December 31, 2004, have been translated into United
States dollars solely for the convenience of the readers. We have audited the translation and, in our opinion, the consolidated financial statements expressed in New Taiwan dollars have been translated into United States dollars on the basis set
forth in note 2(v) to the consolidated financial statements.



Accounting principles generally accepted in the Republic of China vary in certain significant respects from accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such
differences is presented in note 22 to the consolidated financial statements.

Notes to Consolidated Financial Statements

As of and for the years ended December 31, 2002, 2003 and 2004



(1) Organization



AU Optronics Corp. (AUO) was founded in the Hsinchu Science Park of the Republic of China on August 12, 1996. AUOs main activities are
the research, development, production and sale of thin film transistor liquid crystal displays (TFT-LCDs), and other flat panel displays used in a wide variety of applications, including notebook personal computers, desktop monitors,
televisions, personal digital assistants, car televisions, digital cameras and camcorders, car navigation systems and mobile phones. AUOs common shares were publicly listed on the Taiwan Stock Exchange in September 2000 and its American
Depositary Shares (ADSs) were listed on the New York Stock Exchange in May 2003.



On May 10, 2001, the Companys stockholders approved a proposal to merge with Unipac Optoelectronics Corp. (Unipac). Unipac was subsequently dissolved. Unipac was principally engaged in the research,
development, design, manufacture and sale of TFT-LCD and LCD modules used in wide variety of applications, including notebook, personal computers, desktop monitor, digital cameras and camcorders, car televisions, car navigation systems, personal
digital assistants and internet appliances. On September 1, 2001, Unipac was merged with and into the Company in a transaction accounted for in accordance with the pooling-of-interests method of accounting.



AU Optronics (L) Corp. (AUL) is a wholly owned subsidiary of AUO
and was incorporated in September 2000. AUL is a holding company investing in the wholly owned foreign subsidiaries including AU Optronics Corporation America (AUA), AU Optronics (Suzhou) Corp. (AUS), AU Optronics Europe B.V.
(AUE), AU Optronics Korea Ltd. (AUK) and AU Optronics Corporation Japan (AUJ). AUS is engaged in the assembly of TFT-LCD module products in Mainland China. AUA, AUJ, AUE and AUK are mainly engaged in the sale of TFT-LCDs.



Konly Venture Corp. (Konly), a wholly owned subsidiary of AUO,
was incorporated in August 2002. Konly is an investment holding company for investments in other technology companies.



As of December 31, 2004, AUO and its consolidated subsidiaries have 19,907 employees.



(2) Summary of Significant Accounting Policies



(a) Accounting principles and consolidation policy



The consolidated financial statements include the accounts of AUO and the
aforementioned subsidiaries, hereinafter, referred to individually or collectively as the Company.



The consolidated financial statements are prepared in accordance with the Guideline Governing the Preparation of Financial Report by Securities Issuers
and accounting principles generally accepted in the Republic of China (ROC GAAP). These consolidated financial statements are not intended to present the financial position and the related results of operations and cash flows of the
Company based on accounting principles and practices generally accepted in countries and jurisdictions other than the Republic of China.



All significant inter-company balances and transactions are eliminated in the consolidated financial statements.



(b) Revenue recognition



Revenue is recognized when title to the products and risk of ownership are

As of and for the years ended December 31, 2002, 2003 and 2004



Allowance and related provisions for sales returns are estimated based on historical experience. Such
provisions are deducted from sales in the year the products are sold.



(c) Use of estimates



The
preparation of the accompanying consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the
consolidated financial statements and reported amounts of revenues and expenses during the reporting periods. Economic conditions and events could cause actual results to differ significantly from such management estimates.



(d) Foreign currency transactions and translation



AUOs functional currency is the New Taiwan dollar. The
Company and its subsidiaries record transactions in their respective local currencies. The translation from the applicable foreign currency assets and liabilities to the New Taiwan dollar is performed using exchange rates in effect at the balance
sheet date except for stockholders equity, which is translated at historical exchange rates. Revenue and expense accounts are translated using average exchange rates during the year. Gains and losses resulting from such translations are
recorded as a cumulative translation adjustment, a separate component of stockholders equity.



Foreign currency transactions are recorded at the exchange rates prevailing at the transaction dates. At the balance sheet date, monetary assets and
liabilities denominated in foreign currencies are translated using the exchange rates prevailing on that date. The resulting exchange gains or losses from settlement of such transactions or translations of monetary assets and liabilities are
reflected in the accompanying consolidated statements of operations.



(e) Cash equivalents and restricted cash in bank



The Company considers all highly liquid investments, such as investments in government bonds with repurchase agreements, original with maturity of three months or less to be cash equivalents. Time deposits, which are
provided as collateral, are classified as current assets or non-current assets depending on the term of the obligation secured by such collateral.



(f) Short-term investments



Short-term investments, which consist primarily of marketable securities such as publicly listed stock, open-end mutual funds, are recorded at cost when
acquired and are stated at the lower of aggregate cost or fair value at the balance sheet date. The fair value of listed stocks is determined by the average closing prices during the last month prior to the balance sheet date. The fair value for
open-end mutual funds is determined by their net asset value at the balance sheet date. The amount by which the aggregate cost of the entire portfolio exceeds fair value is reported as a loss in the current year. In subsequent periods, recoveries of
fair value are recognized as a gain to the extent that the fair value does not exceed the original aggregate cost of the investment. Valuation losses are recorded as non-operating expenses in the accompanying consolidated statements of operations.
Losses due to permanent impairment are charged to the statement of operations at the time the impairment occurs. Stock dividends are not treated as income, but as an increase in shares held.



(g) Allowance for doubtful accounts and sales returns and
discounts



The allowance for doubtful accounts is based on the
age, credit quality and results of the Companys evaluation of collectibility of the outstanding balance of notes and accounts receivable. An allowance for sales

returns and discount is based upon managements estimation of sales returns based upon actual experience and managements granting of sales discounts to
certain customers subsequent to the initial sale of product.



(h) Inventories



Inventories
are stated at the lower of cost or fair value. Cost is determined using the weighted-average method. The fair value of raw material is determined on the basis of replacement cost. Fair values of finished goods and work-in-process are determined on
the basis of net realizable value. A provision for inventory obsolescence and devaluation is recorded when management determines that the fair values of inventories are less than its cost basis. The provision is calculated based on, in part, the
number of months inventory items remain unsold.



(i) Long-term investments



Long-term equity
investments in which the Company is not able to exercise significant influence over the investees operations and financial policies, generally those in which it owns less than 20% of the investees voting shares are accounted for by the
cost method if the investee is an unlisted company, otherwise, by the lower of cost or market value if the investee is a listed company. If there is evidence indicating that a decline in the value of an investment is other than temporary, then the
carrying amount of the investment is reduced to reflect its net realizable value. The related loss is recognized in the accompanying consolidated statements of operations.



When the Company has significant influence over the operating, financial and dividend policies of investees or has the
intention to hold the investment for a long term period, generally those in which it owns between 20 and 50 percent of the investees voting shares, those investments are accounted for using the equity method. The difference between the
acquisition cost and the carrying amount of net equity of the investee as of the acquisition date is allocated based upon the prorate excess of fair value over the carrying value of assets on the investees books. Allocated amount are amortized
based on the method used for the related asset. Any unallocated amount shall be amortized over five years using the straight-line method. The amortization is recorded as investment income (loss) in the accompanying consolidated statements of
operations.



If an investee company issues new shares and the
Company does not acquire new shares in a proportion to its original ownership percentage, the Companys equity in the investees net assets will be changed. The change in the equity interest shall be used to adjust the capital surplus and
long-term investments accounts. If the Companys capital surplus is not sufficient to offset the adjustment to long-term investment, then the difference shall be debited to retained earnings. If investees are unable to forward their audited
financial statements in timely fashion, the Company recognizes the income (loss) of the investees in the following year. This time lag is consistent from period to period.



Unrealized inter-company profits or losses resulting from transactions between the Company and an investee accounted for
under the equity method are deferred. The profits or losses resulting from depreciated or amortized assets are recognized over the estimated economic lives of such assets. The profits or losses from other assets are recognized when realized.



The differences resulting from translation of the financial
statements of the foreign investees accounted for under the equity method into New Taiwan dollars, net of the related tax effect, are recorded as cumulative translation adjustments, a separate component of stockholders equity.

(j) Property, plant and equipment



Property, plant and equipment are stated at acquisition cost. Excluding
land, depreciation of property, plant and equipment is provided over the estimated useful lives of the respective assets using the straight-line method less any salvage value. The range of the estimated useful lives are as follows: buildings20
to 50 years, machinery and equipment3 to 10 years, leasehold improvementshorter of 5 years or the lease term, and other equipment3 to 5 years. Interest costs related to the construction of property, plant and equipment are
capitalized and included in the cost of the related asset. Maintenance and repairs are charged to expense as incurred. Significant renewals and improvements are treated as capital expenditure and are depreciated accordingly. Property, plant and
equipment leased to other parties under operating lease are classified as leased assets. Property, plant and equipment not in use are classified as idle assets and are stated at the lower of carrying amount or net realizable value.



(k) Impairment of long-lived assets and long-lived assets to
be disposed of



Long-lived assets and certain identifiable
intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying
amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is the amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.



(l) Technology related fees



The costs resulted from patent and license of the product and process technology for TFT-LCDs and other flat-panel displays are capitalized and amortized
over the respective contract period of 3 to 15 years on a straight-line basis. The amortization of the technology fixed license fees is included in research and development expenses in the consolidated statements of operations. On-going royalty fees
associated with product production and sales related to these licenses are included in costs of goods sold in the consolidated statements of operations.



(m) Deferred charges



The cost of software systems, electrical facility installation charges, syndicated loan, bond issuances and land use right are accounted for as deferred
charges. The costs of the software systems are amortized over the estimated useful lives of three years on a straight-line basis, and electrical facility installation charges are amortized over the estimated useful lives of five years on a
straight-line basis. The expenses associated with the syndicated loan are amortized over the term of the debt on a straight-line basis. The expenses associated with issuing bonds payable and convertible bonds are amortized by using the straight-line
method over the period from the issuance date to the maturity date (five or seven years). When the bondholder exercise the conversion option or the Company early extinguishes of convertible bonds, the unamortized issuance expenses will be write-off.
The cost of land use right is amortized by using the straight-line method over twenty years.



(n) Convertible bonds



The Company issued convertible bonds, which provide for early redemption at the option of the Company or bondholders at a premium over par value. The
excess of the stated redemption price over the par value is accrued as provision for early redemption during the redemption period, using the effective interest method. When the redemption right expires, the balance of the provision for early
redemption is amortized over the period from the expiration date to the maturity date using the effective interest method.



If the bondholders exercise their conversion right, the unamortized issuing costs, forfeited unpaid interest, provision for early redemption and par value
of the extinguished bonds are transferred to stockholders equity.

The excess of such amounts over the par value of the stock for conversion of the convertible bond is recorded as capital surplus in the accompanying
consolidated balance sheets, and no gain or loss is recognized on bond conversion.



(o) Employee retirement plan



AUO has established a noncontributory employee, defined benefit retirement plan (the Plan) covering full-time employees in the Republic of China. In
accordance with the Plan, employees are eligible for retirement or are required to retire after meeting certain age or service requirements. Payments of retirement benefits are based on years of service and the average salary for the six-month
period before the employees retirement. Each employee earns two months of salary for the first fifteen years of service, and one month of salary for each year of service thereafter. The maximum retirement benefit is 45 months of salary. The
plan is funded by contributions made by AUO, plus earnings thereon. On a monthly basis, AUO contributes two percent of wages and salaries to a pension fund maintained with the Central Trust of China. Retirement benefits are paid to eligible
participants on a lump-sum basis upon retirement.



AUO has
adopted Republic of China Statement of Financial Accounting Standards (SFAS) No. 18, Accounting for Pensions, for the plan. SFAS No. 18 requires AUO to perform an actuarial calculation on its pension obligation as of each fiscal
year-end. Based on the actuarial calculation, AUO recognizes a minimum pension liability and net periodic pension costs covering the service lives of the Plan participants.



(p) Treasury stock



The Company has adopted Republic of China SFAS No. 30, Accounting for Treasury Stock for treasury stock
repurchased by the Company. SFAS No. 30 requires that treasury stock be accounted for under the cost method. The cost of treasury stock is shown as a deduction to stockholders equity, while any gain or loss from selling treasury stock is
treated as an adjustment to capital surplus or retained earnings.



(q) Government grants



Income
from government grants for research and development is recognized as non-operating income in the accompanying consolidated statements of operations as qualifying expenditures are made and the grant income is realizable.



(r) Income tax



Income taxes are accounted for under the asset and liability method.
Deferred income taxes are determined based on differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect during the years in which the differences are expected to reverse. The income tax
effects resulting from taxable temporary differences are recognized as deferred income tax liabilities. The income tax effects resulting from deductible temporary differences, net operating loss carryforwards and income tax credits are recognized as
deferred income tax assets. The realization of the deferred income tax assets is evaluated, and if it is considered more likely than not that the deferred tax assets will not be realized, a valuation allowance is recognized accordingly.



Classification of the deferred income tax assets or liabilities as current
or non-current is based on the classification of the related asset or liability. If the deferred income tax asset or liability is not directly related to a specific asset or liability, then the classification is based on the expected realization
date of such deferred income tax asset or liability.

According to the Republic of China Income Tax Law, AUOs undistributed income, if any, earned
after December 31, 1997, is subject to an additional 10 percent retained earning tax. The surtax is charged to income tax expense after the appropriation of earnings is approved by the stockholders in the following year.



(s) Investment tax credit



Income tax expense is reduced by investment tax credits in the year in which
the credit arises, subject to any valuation allowance thereon.



(t) Derivative financial instruments



(i) Forward foreign currency exchange contracts



Forward foreign currency exchange contracts are entered to hedge currency fluctuations affecting foreign currency transactions. These forward exchange contract receivables and payables are recorded at the spot rate at
the date of inception. The discount or premium is amortized on a straight-line basis over the life of the contract. Realized and unrealized gains or losses on these contracts resulting from actual settlement or balance sheet date translation are
charged or credited to current operations.



(ii) Interest rate
swaps



The Company enters into interest rate
swap contracts to hedge changes in cash flows associated with existing variable rate of long-term debt. Under this interest rate swap contracts, the Company makes specified payments based on fixed interest rate and notional principal amounts and
receives amounts based on variable rate of interest and notional principal. The net amounts received or paid under the contracts are reported as adjustments to interest expense or interest income on long-term debt.



(u) Earnings per common share



Earnings per share of common stock (EPS) is computed based on
the weighted-average number of common shares and certificates exchangeable for common stock outstanding during the period. The Company issued convertible bonds in November 2001 all of which were converted as of December 31, 2003. Therefore, diluted
EPS for the years ended December 31, 2002 and 2003 is disclosed to reflect the diluted effect of the assumed conversion of the convertible bonds as of the beginning of the period. EPS for prior periods has been retroactively adjusted to reflect the
effects of stock issued from stock dividends and new common stock issued through unappropriated earnings and capital surplus.



(v) Convenience translation into U.S. dollars



The consolidated financial statements are stated in New Taiwan dollars. Translation of the 2004 New Taiwan dollar amounts into U.S. dollar amounts is
included solely for the convenience of the readers, using the noon buying rate of the Federal Reserve Bank in New York on December 31, 2004, of NT$31.74 to US$1. The convenience translations should not be construed as representations that the New
Taiwan dollar amounts have been, could have been, or could in the future be converted into U.S. dollars at this rate or any other rate of exchange.

Notes to Consolidated Financial Statements(Continued)

As of and for the years ended December 31, 2002, 2003 and 2004



Investments in affiliated companies accounted for under the equity method on December 31, 2004
consist of 41% of the common stock of Patentop, an intellectual property company, 32.79% of the common stock of Raydium, an IC design company, 21.46% of Cando, a color filter manufacturing company and 5.47% of BenQ, a manufacturer and distributor of
computer peripheral equipment and communication products.



In
November 2003, the Company purchased its 12.31% ownership in Cando concurrently with the purchase by a related party of 15.66% of Cando at the same time. The Company and the Companys affiliates hold two boards of director seats in Cando, and
have significant influence over Candos day-to-day operations. As such, the Company began account for its investment in Cando under the equity method of accounting effective upon its initial investment in 2003. In February and May 2004, the
Company made additional investments in Cando resulting in a 21.46% ownership at December 31, 2004.



In March 2003, the Company purchased its 20% ownership in FDTC. Under the terms of the purchase agreement, the Company maintained a board of director
seat, entered into a technology licensing agreement, and participated in, certain joint research and development projects related to TFT-LCD technologies. However, in August 2004, the Company sold half of its investment in FDTC and forfeited its
right to appoint a member of the board of directors. The Company is no longer able to exercise significant influence over FDTC. The Company recorded this investment under cost method since September 2004.



In 2004, AUO purchased 126,600 thousand shares of BenQ via open market by its
cash hand, represent 5.47% of BenQs total outstanding shares. The total investment amounted to NT$4,108,923 thousand. The difference between the acquisition cost and the net equity of the investee as of the acquisition date is amortized based
on the nature of their source, except for those from permanent assets. If the source of it cannot be identified, such difference is amortized over five years using the straight-line method. As the Company and BenQ share a common chairman and chief
executive officer, a second officer board member, and have other commercial relationships, the Company is deemed to have significant influence over BenQ. As such, the Company accounts for its investment in BenQ under the equity method of accounting.



As Patentop and FDTC are unable to forward their stand-alone
audited financial statements in a timely fashion, the Company recognizes the income (loss) of these investees in the following year.



The investment losses (gains) related to investment accounted for under the equity method were NT$10,475 thousand, NT$14,449 thousand and
(NT$34,268)(US$1,080) thousand for the years ended December 31, 2002, 2003 and 2004, respectively.

(13) Stockholders Equity



(a) Common stock and capital increase



The Republic of China Company Law and ROC GAAP provide that
capital is created from stock issuance and donated capital. Additionally, companies can transfer capital to common stock as a result of certain transactions involving employee bonuses, donated capital and premium on issuance of common stock.



On May 29, 2002, the Company issued 500 million shares of its
common stock in the form of 50 million American Deposition Shares (ADSs). Each ADS represents the right to receive 10 shares of common stock. The public offering price per ADS was US$11.57. The stock issuances described above were
authorized by and registered with the government authorities.



Based on stockholder resolutions on May 29, 2003, the Company increased its authorized common stock to NT$58,000,000 thousand and of which reserved NT$1,000,000 thousand for issuance of certificates of employee stock options. In addition,
the Company increased its common stock by NT$2,440,549 thousand, par value NT$10 per share, through the transfer of retained earnings and employee bonuses of NT$2,006,917 thousand, and NT$433,632 thousand, respectively.



Based on stockholder resolutions on April 29, 2004, the Company increased its
common stock by NT$3,058,037 thousand, par value NT$10 per share, through the transfer of retained earnings and employee bonuses of NT$2,170,119 thousand and NT$887,918 thousand, respectively. The stock issuances described above were authorized by

Company issued 300 million shares of its common stock in the form of 30 million ADS on June 23, 2004. Each ADS represents the right to receive 10 shares of
common stock. The public offering price per ADS was US$16.00.



As of December 31, 2003 and 2004, the Companys authorized common stock, par value NT$10 per share, amounted to NT$58,000,000, and the issued and outstanding common stock amounted to NT$43,522,372 thousand and NT$49,580,409 thousand,
respectively.



(b) Capital surplus



Pursuant to the Republic of China Company Law, the capital surplus has to
be used to offset a deficit, and then the capital surplus resulting from the income derived from the issuance of new shares at a premium and from endowments received by the Company can be used to increase common stock. Furthermore, pursuant to the
Securities & Futures Exchange Commission (SFC) Law Enforcement Rules, the total sum of capital surplus capitalized per annual may not exceed 10 percent of the paid-in capital. Additionally, the capital surplus realized from a capital
increase or other source shall be capitalized only in the following fiscal year after being registered by the Company with the competent authority for approval.



Based on a stockholders resolution on May 21, 2002, the Company offset the accumulated deficit as of December 31, 2001, with the capital surplus
resulting from gain on disposal of assets of NT$99 thousand, and the capital surplus resulting from the Unipac merger of NT$3,765,730 thousand.



(c) Legal reserve



According to the Republic of China Company Law, the Company must retain 10 percent of its annual income as a legal reserve until such retention equals the
amount of authorized common stock. The retention is accounted for by transfers to a legal reserve upon approval at the annual stockholders meeting. The legal reserve can only be used to offset an accumulated deficit and cannot be distributed
as cash dividends.



Based on a stockholders resolution on
May 21, 2002, the Company offset the accumulated deficit as of December 31, 2001, with the legal reserve of NT$232,014 thousand.



(d) Distribution of earnings and dividend policy



According to the Companys articles of incorporation, 10% of the Company income, after offsetting any accumulated
deficit, shall be set aside as a legal reserve. After establishing the legal reserve, earnings may be distributed in the following order in accordance with the Companys articles of incorporation:



(i) 5 to 10 percent as employee bonuses



(ii) At most 1 percent as remuneration to directors and
supervisors



(iii) The remainder, after
retaining a certain portion for business consideration, as common stockholders dividends.



The appropriation of the Companys net income may be distributed by way of cash dividend and/or stock dividend. Since the Company is in a
capital-intensive industry, distribution of profits shall be made preferably by way of stock dividend. Distribution of profits may also be made by way of cash dividend, and the amount of that should exceed or equal 10% of total dividends.

According to SFC regulations, when there is a deduction item in stockholders equity during the

Pursuant to Republic
of China Income Tax Law, certain portions of loss carryforwards prior to the Unipac merger are not eligible for use by the Company after the merger. As a result, deferred tax assets related to the loss carryforwards that were previously recognized
by the Company were written off in 2002.

(d) According to the Statute for
Upgrading Industries, the purchase of machinery for the automation of production and pollution control, expenditure for research and development and training of professional personnel entitles the Company to tax credits. This credit may be applied
over a period of five years. The amount of the credit that may be applied in any year except the final year is limited to 50% of the income tax payable for that year. There is no limitation on the amount of investment tax credit that may be applied
in the final year. As of December 31, 2004, the Companys remaining investment tax credits and their related expiration years were as follows:



|                 |  |                    |  |                 |  |

(e) Loss carryforwards



As of December 31, 2004, the 2001 loss carryforwards of NT$2,393,749
thousand are available up to 2006 to reduce taxable income.



(f) The
Companys 1997 and 1998 income tax returns have been assessed by the tax authorities for additional income tax payable of NT$30,122 thousand due to the reduction of certain tax credits, plus penalties of NT$7,510 thousand. The additional
assessments were related to recognition of research and development subsidies. The Company disagreed with the assessments and subsequently filed tax appeals. The tax authorities have agreed to eliminate any penalties, but have affirmed the reduction
of tax credits of 1997. The assessment of tax credits of 1998 is still under review. The Company has accrued the additional income tax assessed in 2004.



The 2000 income tax return has been assessed by the tax authorities for additional income tax of NT$9,604 thousand. The dispute is regarding the
recognition of the advertising expenses. The Company disagreed with the assessment and subsequently filed a tax appeal. As the Company believes that it has adequate documents for the expense it is expecting a favorable resolution of this appeal.



As of December 31, 2004, the tax authorities had assessed the
income tax returns of the Company through 2000 and of Unipac through 1999.



(g) Information about the integrated income tax system



Beginning in 1998, an integrated income tax system was implemented in the Republic of China. Under the new tax system, the income tax paid at the corporate level can be used to offset the Republic of China resident
stockholders individual income tax. The Company is required to establish an imputation credit account (ICA) to maintain a record of the corporate income taxes paid and imputation credit that can be allocated to each stockholder. The credit
available to the Republic of China resident stockholders is calculated by multiplying the dividend by the creditable ratio. The creditable ratio is calculated as the balance of the ICA divided by earnings retained by the Company since January 1,
1998.



Information related to the ICA is summarized below:

The following methods
and assumptions are used to estimate the fair value for each class of non-derivative financial instruments:



1. The carrying amounts of cash and cash equivalents, notes and accounts receivable, restricted cash in banks, other financial
assets-current, accounts payable, payables to related parties, equipment and construction in progress payables and short-term borrowings approximate their fair value due to the short-term nature of these items.



2. The fair value of short-term investments is based on
publicly quoted market prices.



3. It is not
practicable to determine the fair value of long-term equity investments when these investments are not publicly traded. Refer to note 8 for information on the carrying amount.



4. Long-term borrowings are issued at floating rates. The fair value approximates their carrying value.
Refer to note 11.



5. The fair value of bonds
payable is based on the present value.

Notes to Consolidated Financial Statements(Continued)

As of and for the years ended December 31, 2002, 2003 and 2004



The Company maintains its cash and short-term investments with various reputable financial
institutions. The Company performs periodic evaluations of the relative credit standing of these financial institutions and limits the amount of credit exposure with any one institution. As a result, the Company believes that there is a limited
concentration of credit risk in cash and investments.



The
majority of the Companys customers are in the notebook personal computer and LCD monitor industry. The Company continuously evaluates the credit quality of its customers. If necessary, the Company will require collateral from those customers.
In addition, the Company evaluates the collectibility of trade receivables and provides adequate reserves for bad debts, if necessary. It is managements belief that there will be no significant losses due to concentration of credit.



2. Credit risk relating to derivative instruments



Credit risk represents the accounting loss that would be recognized at
the reporting date if the counter parties failed to perform. Credit risk will increase as the derivative instruments become more profitable to the Company. The Company entered into the above derivative contracts with major international foreign
banks or reputable local banks. The likelihood of default on the part of the banks is considered remote.



3. Market price risk relating to derivative instruments



Market price risk represents the accounting loss that would be recognized at the reporting date for the derivative financial instruments due to the
changes in market interest rates or foreign exchange rates. As the Companys derivative financial instruments are for hedging purposes, the gains or losses due to changes in interest rates or foreign exchange rates will be offset by the hedged
items. As a result, market price risk is considered low.



4.
Liquidity risk



Liquidity risk is the risk of being unable to
settle the derivative contracts on schedule. The purpose of these instruments held by the Company is to manage and hedge changes in cash flows and risks associated with floating interest rate debt and foreign currency rates. There is no significant
liquidity risk for the related cash flows.



The fair values of
the financial instruments disclosed herein are not necessarily representative of the potential gain or loss that could be realized under current credit and market price risks. The Company does not believe a significant loss on the above financial
derivative contracts will occur.

|Note 1: | Since UMC has disposed half of its shares held in AUO on April 22, 2004, its membership or the board of directors has been dissolved automatically. Consequently, UMC and the
investees of UMC are not regarded as AUOs related parties, and the amount of transactions between them and AUO are disclosed until the end of April 2004.
|------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

regarded as AUOs related party, and the amount of transactions between FDTC and AUO are disclosed until the end of August 2004.

(22) Summary of Significant
Differences Between Accounting Principles Followed by the Company and Accounting Principles Generally Accepted in the United States of America



The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the Republic of China
(ROC GAAP), which differ in certain significant respects from accounting principles generally accepted in the United States of America (US GAAP). A discussion of the significant differences between US GAAP, and, ROC GAAP as they apply to the Company
is as follows:



(a) Business combination



AUO completed its merger with Unipac on September 1, 2001,
through the issuance of 1,512,281 thousand common shares in exchange for all of the outstanding shares of Unipac. Under ROC GAAP, the merger was

accounted for using the pooling-of-interests method and, accordingly, the assets and liabilities of Unipac were recorded based on the carrying value at the
date of the merger. Further, according to the Republic of China Company Law, the excess of Unipacs net assets over the par value of the Companys issued common stock for completion of the merger was appropriated from unappropriated
earnings and recorded as capital surplus. Under US GAAP, the merger was accounted for as the acquisition of Unipac by the Company using the purchase method of accounting. Under purchase accounting, the aggregate purchase price of NT$39,636,901
thousand was calculated based on the market value of the shares issued, and such amount was allocated to the assets acquired and liabilities assumed based on their respective fair values. The market value of the shares was based on the average
market price of the Companys common shares over the five-day period before and after the terms of the acquisition were agreed upon and announced. The difference between the purchase price and the fair value of the assets acquired, including
identifiable intangible assets, and liabilities assumed of Unipac was recorded as goodwill.



AUOs management is responsible for the determination of the fair value of the assets acquired, including identifiable intangible assets, and liabilities assumed of Unipac. In determining such fair values,
management considered a number of factors, including valuation reports by third parties. The following table summarizes the estimated fair value of the assets and liabilities of Unipac at the date of acquisition.

Of the NT$8,730,382
thousand of acquired intangible assets, NT$53,450 thousand was assigned to in-process research and development assets that were written off at the date of acquisition in accordance with Financial Accounting Standards Board (FASB) Interpretation No.
4, Applicability of FASB Statement No. 2 to Business Combinations Accounted for by the Purchase Method. Those write-offs are included in research and development expenses. The remaining NT$8,676,932 thousand of acquired intangible assets
has a weighted average useful life of approximately 88 months and no estimated residual value. Such intangible assets include large-size TFT-LCD panels product and process technology of NT$3,123,655 thousand and small and mid-size TFT-LCD
panels product and process technology of NT$5,553,277 thousand. The key technology for small and mid-size TFT-LCD production includes the technologies independently developed by Unipac and 13 related patents. The key technology for large-size
TFT-LCD production includes the technologies jointly developed by Unipac and Matsushita Electric Industrial Co., Ltd., (Matsushita), product technologies developed by Unipac and the three related patents.

As of and for the years ended December 31, 2002, 2003 and 2004



The fair value of Unipacs inventory (represented by estimated selling prices less the sum of
costs of disposal and a reasonable profit allowance for the selling effort) was less than its carrying amount by approximately NT$387,901 thousand at September 1, 2001. As a result, the amount allocated to Unipacs inventory in connection with
the purchase price allocation performed under US GAAP was NT$387,901 thousand less than the carrying value of Unipacs inventory under ROC GAAP. The majority of the affected inventory was sold prior to December 31, 2001, which resulted in lower
cost of sales of NT$331,656 thousand under US GAAP as compared to ROC GAAP for the year ended December 31, 2001. The remainder of the affected inventory was sold in 2002, which resulted in lower cost of sales of NT$56,245 thousand under US GAAP as
compared to ROC GAAP.



The remaining purchase price of
NT$11,599,692 thousand was allocated to goodwill. Pursuant to Statement of Financial Accounting Standards (SFAS) No. 141, Business Combinations, goodwill arising from purchase business combinations consummated after June 30, 2001, is not
amortized but is tested for impairment. Amortization of goodwill is not deductible for tax purposes.



There were deferred tax assets of NT$652,960 thousand with a related valuation allowance for deferred tax assets of NT$652,960 thousand and deferred tax
liabilities of NT$680,849 thousand, respectively, which were recorded as part of the purchase accounting at September 1, 2001. As the Company continues to generate profits after 2002, the valuation allowance was released. In accordance with SFAS No.
109, the release of a valuation allowance for deferred tax assets that were created from a purchase accounting transaction results in a reduction in goodwill rather that a benefit recorded in the income statement.



Effective January 1, 2002, for US GAAP purposes, the Company adopted SFAS No.
142, Goodwill and Other Intangible Assets. SFAS No. 142 classifies intangible assets into three categories: 1) intangible assets with definite lives subject to amortization; 2) intangible assets with indefinite lives not subject to
amortization; and 3) goodwill. For intangible assets with definite lives, tests for impairment must be performed if conditions exist that indicate that the carrying value may not be recoverable. The Company has no intangible assets with indefinite
lives.



The Company performs tests of impairment of goodwill
annually or more frequently if events or circumstances indicate it might be impaired. The Company has determined that it is a single reporting unit for purposes of testing goodwill for impairment. Accordingly, the Company compares its total
stockholders equity (determined on a U.S. GAAP basis) to its market value (based on the quoted value of its common stock) on the impairment evaluation date to determine if goodwill is potentially impaired. Based on these assessments, the
Company concluded that goodwill was not impaired.



The
Companys product and process technology intangible assets are amortized over their useful lives. The Company reviews such product and process technology assets with definite lives for impairment to ensure they are appropriately valued if
conditions exist that may indicate the carrying value may not be recoverable. Such conditions may include an economic downturn in a geographic region, or a change in the assessment of future operations.



During 2004, the Company recognized the other than temporary impairment of an
investment in marketable securities that was originally recorded in connection with the merger with Unipac. The adjustments to net income determined in accordance with US GAAP for the year ended December 31, 2004 present separately that portion of
the impairment related to the increase in carrying amount from the application of purchase accounting and the amount related to Unipacs original basis.

(b) Compensation



(i) Remuneration to directors and supervisors



AUOs articles of incorporation specify a remuneration amount up to 1% of annual distributable earnings to be paid to
its directors and supervisors. Under ROC GAAP, such payments are charged directly to retained earnings in the period stockholders approve such payment and treated as financing activities in the statements of cash flow.



Under US GAAP, such cash payments should be recorded as compensation expense
in the period when the related services are rendered and treated as operation activities in the statements of cash flow.



(ii) Employee bonuses



Certain employees of AUO are entitled to bonuses in accordance with provisions of AUOs articles of incorporation, which specify a bonus amount
ranging from 5 % to 10 % of annual distributable earnings. Employee bonuses may be paid in cash, shares, or a combination of both. Under ROC GAAP, such bonuses are appropriated from retained earnings in the period stockholders approval is
obtained. If such employee bonuses are settled through the issuance of stock, the amount charged against retained earnings is based on the par value of the common shares issued. Under US GAAP, employee bonus expense is charged to income in the year
services are provided. Shares to be issued as part of these bonuses are recorded at fair value determined at the date on which the number of shares to be issued is known. Since the amount and form of the bonuses are not determinable until the
stockholders meeting in the subsequent year, the total amount of the bonus is initially accrued based on the best estimation of employee bonus to be paid in cash. Any difference between the amount initially accrued and fair value of bonuses
settled by the issuance of shares is recognized in the year of approval by the stockholders.



(c) Equity method investments



In March 2003, the Company purchased a 20% equity ownership in FDTC, that resulted in recognition of investor level goodwill of NT$240,179 thousand. Such investor level goodwill is not amortized but rather the total carrying value of the
investment is tested for impairment if events or circumstances indicate it might be other than temporarily impaired under US GAAP. Under ROC GAAP, the investor level goodwill is amortized on a straight-line basis over five years. In August 2004, the
Company disposed 10% ownership representing a 10 percent interest in FDTC and became unable to exercise the significant influence over FDTC. As a result starting September 2004, the investment in FDTC is accounted for by the cost method.



The Company held a 21% ownership interest in PixTech as of December 31,
2002. Under ROC GAAP, because the Company had no intention to hold PixTechs stock for the long term, the investment in PixTech was recorded as a short-term investment and accounted for at the lower of aggregate cost or fair value with changes
in fair value being reported in the consolidated statements of operations. Under US GAAP, the investment in PixTech was accounted for under the equity method.



In 2002, the Company wrote off the value of its investment in PixTech due to the other than temporary decline in investment value for both ROC GAAP and
US GAAP. As a result, the December 31, 2002 US GAAP adjustment related to PixTech consists of the difference in the amount of the write off due to the different carrying amounts of this investment under both ROC GAAP and US GAAP.



In November 2003, the Company purchased its 12.31% ownership in Cando and
accounted for its investment under the equity method of accounting. The difference between the acquisition cost and the carrying

Notes to Consolidated Financial Statements(Continued)

amount of net equity of the investee as of the acquisition date is allocated based upon the prorate excess of fair value over the carrying value of assets on
investees books. Any unallocated difference is treated as investor level goodwill. Under ROC GAAP, the amount of NT$22,769 thousand is amortized over five years. Under US GAAP, it is not amortized, but rather the carrying value of the total
investment is evaluated for any other than temporary impairment.



If an investee company issues new shares and the shareholders do not acquire new shares in proportion to their original ownership percentage, the investors equity in the investees net assets will be changed. In February and May
2004, the Company made additional investments in Cando. Under ROC GAAP, the change in the equity interest shall be used to adjust the capital surplus and the long-term investments accounts.



If a companys capital surplus is not sufficient to offset the
adjustment to long-term investment, then the difference shall be debited to retained earnings. AUO debited NT$153,569 thousand to the retained earnings in 2004. Under US GAAP, the subsequent investments are treated as a step acquisition. The Company
recorded equity method goodwill of NT$230,616 thousand.



In
2004, the Company purchased its 5.47% ownership in BenQ accounted for its investment under the equity method of accounting. The difference between the acquisition cost and the carrying amount of net equity of the investee as of the acquisition date
is allocated based upon the prorate excess of fair value over the carrying value of assets on investees books. Any remaining excess is considered investor level goodwill. Under ROC GAAP, the investor level goodwill is amortized over five
years; under US GAAP, it is not amortized, but rather the carrying value of the total investment is evaluated for any other than temporary impairment.



As permitted under ROC GAAP, the Company recognizes its equity income (loss) of Patentop and FDTC in the following year on a one-year lag basis. Under US
GAAP, the Company recognizes its equity in the income (loss) of Patentop in the current year on a current year basis.



(d) Marketable securities



Under ROC GAAP, marketable securities are carried at the lower of aggregate cost or market. The fair value is determined by the average price for one
month before the balance sheet date. Under US GAAP, marketable securities that have readily determinable fair values are to be classified as either trading, available-for-sale or held-to-maturity securities. The fair value is determined as of the
balance sheet date. Marketable 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. Marketable securities not classified
as trading securities 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 other comprehensive income. However, when the
investment is deemed to be other than temporarily impaired, it is written down to fair value at the end of the period of assessment through a charge to earnings.



The Company had no trading or held-to-maturity securities as of December 31, 2003 or 2004. At December 31, 2004, the
unrealized loss of one of the Companys available-for-sale securities, which has been in a continuous unrealized loss position for more than twelve months, amounted to NT$922,901 thousand. The Company has determined that the impairment is other
than temporary, and as a result, the unrealized loss of NT$922,901 thousand has been written off to current operations.



(e) Provision for inventory obsolescence and devaluation



A provision for inventory obsolescence and devaluation is recorded when management determines that the realizable values of
inventories are less than their cost basis. Under ROC GAAP, such provisions can be reversed

in whole or in part if management further determines that the realizable values of inventories are greater than their cost basis. Under ROC GAAP, the Company
recorded a reversal of obsolescence and devaluation provisions of NT$33,945 thousand for the year ended December 31, 2002. Under US GAAP, provisions for inventory obsolescence and devaluation become a permanent adjustment to the carrying amount of
the specific inventory, and cannot be reversed once they are recorded.



(f) Convertible bonds



When
convertible bonds are issued, ROC GAAP does not recognize or account for any beneficial conversion feature embedded in the bonds. Under US GAAP, beneficial conversion features should be recognized and measured by allocating a portion of the proceeds
equal to the intrinsic value of that feature to capital surplus. In connection with the Companys issuance of convertible bonds in November 2001, the amount of the beneficial conversion feature was calculated at the commitment date as the
difference between the conversion price and the fair value of the common stock, multiplied by the number of shares into which the security is convertible. As a result of allocating a portion of the proceeds equal to the intrinsic value of the
beneficial conversion feature to capital surplus, a discount on the bonds was recognized. The discount resulting from such allocation is recognized as interest expense over the life of the convertible debt. The face amount of the convertible bonds
was NT$10,000,000 thousand, and the discount recognized on the date of issuance resulting from the beneficial conversion feature was NT$886,076 thousand. The effective interest rate of the bonds was approximately 6.0%, and their carrying amount at
December 31, 2002 under US GAAP was NT$1,205,996 thousand. The convertible bonds were fully converted in October 2003.



(g) Shareholders stock dividends paid



Under ROC GAAP, shareholders stock dividends paid are recorded at par value, with a charge to retained earnings. Under US GAAP, if the ratio of
distribution is less than 25 % of the same class of shares outstanding, the fair value of the shares issued should be charged to retained earnings. The effect of this dividend decreased retained earnings and increased capital surplus for the years
ended December 31, 2003 and 2004, by NT$2,087,193 thousand and NT$13,671,747 thousand, respectively.



(h) Pension benefits

January 1, 1998, the pension expense recorded by the Company in connection with its defined pension plan was based on contributions made by the Company to the pension plan as required by the Republic of China Labor Standards Law. Effective from
January 1, 1998, the Company adopted ROC GAAP, SFAS No. 18, Accounting for Pensions, which is identical to US GAAP, SFAS No. 87 and 88 with the exception of the accounting upon adoption. Subsequent to January 1, 1998, net pension expense
was recognized on an actuarially determined basis. Under US GAAP, the Company accounts for its defined benefit pension plan in accordance with SFAS No.87, Employers Accounting for Pensions, the accumulated pension obligation and
the pension expense are determined on an actuarial basis from the date the pension plan was started in 1996. Therefore, the pension obligation and related expense will be different because the unrecognized prior service cost is different between ROC
GAAP and US GAAP. In 2003, the Company adopted SFAS No. 132 (revised 2003), Employers Disclosures about Pensions and Other Postretirement Benefits. SFAS No. 132, as revised, requires additional disclosures about assets,
obligations, cash flows and net periodic benefit cost of defined benefit pension plans. This statement did not change the measurement or recognition of those plans required by SFAS No. 87, or SFAS No. 88, Employers Accounting for
Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits. There were no other material differences between ROC GAAP and US GAAP related to pension accounting.

(i) Depreciation of property, plant and equipment



Under ROC GAAP, the Company depreciates buildings over their estimated lives of between 20 to 50 years based on guidance
from the Republic of China Internal Revenue Code. Under US GAAP, buildings are depreciated over an estimated useful life of 20 years.



(j) Derivative financial instruments



The Company operates internationally, giving rise to exposure to changes in foreign currency exchange rates. The Company also has exposure to changes in
interest rates that affect its cash flows on long-term debt. The Company uses financial instruments, including derivatives such as foreign currency forward contracts and interest rate swaps, to reduce this exposure. Under ROC GAAP, the
Companys interest rate swaps are recorded at their unamortized premium, and the Companys forward contracts are recorded at their spot value on the balance sheet date.



Under US GAAP, prior to the adoption of SFAS No. 133, Accounting for Derivative Instruments and Hedging
Activities, as amended, the Company recorded its interest rate swaps as hedge transactions by recording the net receivable or payable each month related to these interest rate swap contracts, offsetting and adding to interest expense of the
related debts. For foreign currency forward contracts prior to the adoption of SFAS No. 133, as amended, the Company recorded unrealized gains or losses measured using the change in spot rate of the contract in the consolidated statements of
operations if the contracts were used to hedge existing foreign currency denominated receivables and payables, or deferred recognition of unrealized gains or losses for those contracts hedging anticipated transactions that would be denominated in a
foreign currency. The discount or premium on a forward contract was amortized into earnings over the life of the contract.



As a result of adopting SFAS No. 133, as amended, as of January 1, 2001, and in accordance with the transition provisions, the Company recorded an after
tax charge of NT$551 thousand representing the cumulative effect of the adoption related to the foreign currency forward contracts, and a cumulative after-tax adjustment to accumulated other comprehensive income of NT$30,937 thousand related to the
interest rate swaps. The transition adjustments recorded upon adoption SFAS No. 133 have been fully amortized as of December 31, 2004.



After the adoption of SFAS No. 133, as amended, none of the Companys existing derivatives meet the US GAAP hedge accounting criteria. All derivative
contracts are recognized as either assets or liabilities and are measured at fair value at each balance sheet date. Changes in fair values of derivative instruments arising subsequent to the transition date are recognized in earnings for US GAAP
purposes. In addition, the Company reclassified NT$9,377 thousand and NT$2,812 thousand, net of tax, of the deferred losses from accumulated other comprehensive income into earnings from the interest rate swap contracts in 2003 and 2004,
respectively. Changes in the fair value of these derivatives in subsequent periods could result in increased volatility of results of operations under US GAAP.



(k) 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 periods subsequent to that in which they are earned are accrued for at each balance sheet date.



(l) Research and development expense



For ROC GAAP, the amortization of the payment of the capitalized technology fixed license and patent fees for product and process technology is included
in research and development expense. For US GAAP, this amortization expense is included in cost of goods sold.

(m) Operating leases



The Company entered into certain non-cancelable lease agreements with rental payments subject to escalation adjustments of 5% each year. Under ROC GAAP,
fixed escalation of rental payment is recognized as they become payable. Under US GAAP, fixed escalation of rental payments is recognized on a straight-line basis over the lease term.



(n) Income tax



Under ROC GAAP, a valuation allowance is provided on deferred tax assets when they are not certain to be realized based on consideration of projection of
future taxable income. However, the criteria by which the need for a valuation allowance is determined is less stringent as compared to US GAAP. Under US GAAP, cumulative losses in recent years are a significant piece of negative evidence which
makes it difficult to support a conclusion that expected taxable income from future operations justifies recognition of deferred tax assets. The Company suffered losses in 2001 and also had a net loss in the fourth quarter of 2002. As a result, the
Company did not use the projection of future taxable income in determining its net deferred tax asset valuation allowance for periods through December 31, 2002. However, as the Company continues to generate taxable income from 2003 onwards, more
positive evidence is available that permits the use of available future taxable income projections in determining the extent of the valuation allowance. As a result, the Company released valuation allowance of NT$1,869,051 thousand in 2003. The
Company did not release any additional valuation allowance in 2004 related to expectations of additional future taxable income.



Under a revised ROC tax rule effective on January 1, 1998, an additional 10 percent corporate income tax will be assessed on taxable income but only to
the extent such taxable income is not distributed before the end of the following year. As a result, from January 1, 1998, to January 20, 2001, the undistributed income of the Company is subject to a corporate tax rate of 28% and distributed income
is taxed at 20%. Commencing from January 20, 2001, the undistributed and distributed income are subject to a corporate tax rate of 32.5% and 25%, respectively. Under ROC GAAP, the 10% tax on undistributed earnings is recognized as an expense at the
date that stockholders resolve the amount of the earnings distribution. Under US GAAP, the Company measures its tax expense, including the tax effects of temporary differences, using the tax rate applicable to undistributed earnings.



(o) Earnings (loss) per share



Under ROC GAAP, basic earnings (loss) per share (EPS) are calculated by dividing net income (loss) by the weighted-average
number of shares outstanding during the year. Diluted EPS is calculated by taking basic EPS into consideration, plus additional common shares that would have been outstanding if the potential diluted shares had been issued. Net income would also be
adjusted for the interest derived from any underlying diluted shares. The weighted-average outstanding shares are restated for shareholders stock dividends issued, including transfers from retained earnings and capital surplus to common stock, and
employee stock bonus issued.



Under US GAAP, the calculation of
basic and diluted EPS is substantially the same as compared to the calculation under ROC GAAP, except for shares issued for employee bonus are not restated. The diluted effects of the Companys convertible bonds issued in November 2001 were
considered in the diluted EPS calculation for the years 2002 and 2003. As the Companys convertible bonds were fully converted in October 2003, there is no diluted effect on the Companys EPS in 2004.

(r) Additional US GAAP Disclosure



(1). Securities available for sale



The Company holds marketable equity securities that are classified as available-for-sale securities. Information on
available-for-sale securities held at each balance sheet date is as follows:



|                        |  |                |  |            |  |                      |  |                       |

|                        |  | NT$            |  | NT$        |  | NT$                  |  | NT$                   |  
|                        |  | (in thousands) | 
|Current assets:         |  |                |  |            |  |                      |  |                       |  
|As of December 31, 2003 |  | 3,241,108      |  | 2,728,410  |  | 26,776               |  | (539,472              | )
|As of December 31, 2004 |  | 2,618,209      |  | 2,676,206  |  | 57,997               |  |                      |  
|Long-term investments:  |  |                |  |            |  |                      |  |                       |  
|As of December 31, 2003 |  | 10,000         |  | 10,000     |  |                     |  |                      |

Under ROC GAAP, fair
value is determined by the average price for one month before the balance sheet date; however, under US GAAP, fair value is determined as of the balance sheet date. The non-current available for sale securities are included in other long-term
investments in the accompanying consolidated balance sheet.



The estimated fair value and gross unrealized losses of one of the Companys available-for-sale securities at December 31, 2004, all of which have been in a continuous unrealized loss position for twelve months or longer, amounted to
NT$1,219,694 thousand and NT$(922,901) thousand, respectively. Such marketable securities are comprised of an investment in a Taiwanese global semiconductor foundry company. The cause of the impairment related to this investment is directly related
to the global downturn in the foundry business cycle that occurred in 2001, and continued throughout 2004. As of December 31, 2004, the Company has determined that the impairment is other than temporary based on its assessment of the characteristics
of the investment, including the historical business cycles that impact the valuations of businesses in the semiconductor industry. Therefore, the Company written off NT$ 922,901 thousand, the difference between the cost and fair value at balance
sheet date, to current operation.



Information on sales of
available-for-sale equity securities for the years ended December 31, 2002, 2003 and 2004 is as follows. The costs of the securities sold were determined on a weighted average basis.

Of the provision charged to
operations, NT$137,947 thousand, NT$41,698 thousand, and NT$9,221 thousand was charged to general and administrative expenses during the years ended December 31, 2002, 2003, and 2004, respectively. The remaining amounts were recorded as an
adjustment of revenue.



(3) Pension Related
Benefits



One of the principal assumptions used to calculate
net periodic pension cost is the expected long-term rate of return on plan assets. The expected long-term rate of return on plan assets may result in recognized returns that are greater or less than the actual returns on those plan assets in any
given year. Over time, however, the expected long-term rate of return on plan assets is designed to approximate the actual long-term returns.



The discount rate assumptions used to account for pension plans reflect the rates available on high-quality, fixed-income debt instruments on December 31
of each year. The rate of increase in compensation is another significant assumption used for pension accounting and is determined by the Company based upon annual review.



Total expense for the Companys defined benefit pension plan amounted to NT$ 60,865 thousand in 2002, NT$ 101,010
thousand in 2003 and NT$136,123 (US$4,289) thousand in 2004.



The Company uses a measurement date of December 31 for its plan.

The following table sets forth the change in benefit obligations for our pension plan:

Plan assets only
contain a Pension Fund (the Fund) denominated solely in cash, as mandated by ROC Labor Standard Law. The Company contributes an amount equal to 2% of salaries paid every month to the Fund (required by law). The Fund is administered by a
pension fund monitoring committee (the Committee) and is deposited in the Committees name in the Central Trust of China. Additional contributions may be required in the future in order to provide for unfunded obligations.



The pension amounts recognized in our balance sheets are as
follows:

In assessing the
realizability of deferred tax assets in accordance with US GAAP, management considers whether it is more likely than not that some portion or all of the deferred tax asets will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the

periods in which those temporary differences become deductible and net operating losses and investment tax credits utilized. Management considers the
scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in
which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences, net operating losses and investment tax credits, net of the existing valuation
allowances at December 31, 2004. The estimate of future taxable income required to realize net deferred tax assets at December 31, 2004, is approximately NT$9,139,600 thousand. The amount of the deferred tax asset considered realizable, however,
could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced.



The valuation allowance at December 31, 2004 represents the amount of tax benefits related to investment tax credits and net operating loss carryforwards,
which management determined are more likely than not to be realized due, in part, to projections of future taxable income. The valuation allowance was NT$6,508,255 thousand as of January 1, 2002. During the years ending December 31, 2002, 2003 and
2004, the valuation allowance increases (decreased) by NT$13,095 thousand, NT$(1,055,521) thousand and NT$840,313 thousand, respectively.



In 2002, 2003 and 2004, the total income taxes are allocated as follows:

Assets held for sale



In July, 2002, the operations of the
Companys Chu-nan fab were moved to other fabs and the Company rented the fab to a third party. In June 2003, the contract was terminated. In December 2003, the Company decided to dispose Chu-nan fab and entered into an agreement with a real
estate agent to sell the property. The Company reclassified it as assets held for sale in December 2003. As of December 31, 2004, it is still the managements intention to sell this property and expect that such sale will be complete within the
current period.



As of December 31, 2003 and 2004, the carrying
amount of the major classes of assets classified as held for sale are as follows:



|                        |  |                |  |           |  |

The impairment loss
recognized in 2003 and 2004 amounted to NT$102,217 thousand and NT$222,868 thousand, respectively. The reason for such impairments is primarily due to the poor market situation of the real estate market in Hsinchu, Taiwan.
