Financial Statements for the
Three Months Ended March 31, 2005 and 2004 and
Independent Accountants’ Review Report

INDEPENDENT ACCOUNTANTS’ REVIEW REPORT

The Board of Directors and Shareholders
Taiwan Semiconductor Manufacturing Company, Ltd.

We have reviewed the accompanying balance sheets of Taiwan Semiconductor Manufacturing Company, Ltd. as of March 31, 2005 and 2004, and the related statements of income and cash flows for the three months then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to issue a report on these financial statements based on our reviews.

We conducted our reviews in accordance with Statement on Auditing Standards No. 36 “Review of Financial Statements” issued by the Auditing Committee of the Accounting Research and Development Foundation of the Republic of China. A review consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in the Republic of China, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to the financial statements referred to above for them to be in conformity with Guidelines Governing the Preparation of Financial Reports by Securities Issuers and accounting principles generally accepted in the Republic of China.

April 13, 2005

Notice to Readers

The accompanying financial statements are intended only to present the financial position, results of operations and cash flows in accordance with accounting principles and practices generally accepted in the Republic of China and not those of any other jurisdictions. The standards, procedures and practices to review such financial statements are those generally accepted and applied in the Republic of China.

For the convenience of readers, the accountants’ report and the accompanying financial statements have been translated into English from the original Chinese version prepared and used in the Republic of China. If there is any conflict between the English version and the original Chinese version or any difference in the interpretation of the two versions, the Chinese-language accountants’ report and financial statements shall prevail.

NOTES TO FINANCIAL STATEMENTS
MARCH 31, 2005 AND 2004
(Amounts in Thousands of New Taiwan Dollars, Unless Specified Otherwise)
(Reviewed, Not Audited)

1.	GENERAL
	Taiwan Semiconductor Manufacturing Company, Ltd. (the Company or TSMC), a Republic of China (R.O.C.) corporation, was incorporated as a venture among the Government of the R.O.C., acting through the Development Fund of the Executive Yuan; Philips Electronics N.V. and certain of its affiliates (Philips); and certain other private investors. On September 5, 1994, its shares were listed on the Taiwan Stock Exchange (TSE). On October 8, 1997, TSMC listed some of its shares of stock on the New York Stock Exchange (NYSE) in the form of American Depositary Shares (ADSs).
	The Company is engaged mainly in the manufacturing, selling, packaging, testing and computer-aided designing of integrated circuits and other semiconductor devices and the manufacturing of masks.
2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	The financial statements are presented in conformity with Guidelines Governing the Preparation of Financial Reports by Securities Issuers and accounting principles generally accepted in the R.O.C.
	For the convenience of readers, the accompanying financial statements have been translated into English from the original Chinese version prepared and used in the R.O.C. If there is any conflict between the English version and the original Chinese version or any difference in the interpretation of the two versions, the Chinese-language financial statements shall prevail.
	Significant accounting policies are summarized as follows:
	Use of Estimates
	The preparation of financial statements in conformity with the aforementioned guidelines and principles requires management to make reasonable assumptions and estimates of matters that are inherently uncertain. The actual results may differ from management’s estimates.
	Classification of Current and Non-current Assets and Liabilities
	Current assets are those expected to be converted to cash, sold or consumed within one year from the balance sheet date. Current liabilities are obligations due on demand within one year from the balance sheet date. Assets and liabilities that are not classified as current are non-current assets and liabilities, respectively.
	Cash Equivalents
	Government bonds under repurchase agreements and notes acquired with maturities less than three months from the date of purchase are classified as cash equivalents.

Short-term Investments

Short-term investments primarily consist of corporate bonds, asset-backed securities, agency bonds, bond funds, government bonds and others.

Short-term investments are recorded at historical cost and are carried at the lower of cost or market value as of the balance sheet date. An allowance for decline in value is provided and is charged to current earnings when the aggregate carrying amount of the investments exceeds the aggregate market value. A reversal of the allowance is recorded for a subsequent recovery of the market value.

The costs of funds and listed stocks sold are accounted for using the weighted-average method; whereas the other securities are accounted for using the specific identification method.

The market value of funds is determined using the net asset value of the funds at the end of the period, and the market value of listed stocks is determined using the average-closing price of the listed stocks for the last month of the period. The market value of other short-term investments are determined using the average of bid and ask prices as of the balance sheet date.

Cash dividends are recorded as investment income in the current period.

Allowance for Doubtful Receivables

An allowance for doubtful receivables is provided based on a review of the collectibility of accounts receivables. The Company determines the amount of allowance for doubtful receivables by examining the historical collection experience and current trends in the credit quality of its customers as well as its internal credit policies.

Revenue Recognition and Allowance for Sales Returns and Others

The Company recognizes revenue when evidence of an arrangement exists, the shipment is made, price is fixed or determinable, and the collectibility is reasonably assured. Revenues from the design and manufacturing of photo masks, which are used as manufacturing tools in the fabrication process, are recognized when the photo masks are qualified by our customers. We record a provision for estimated future returns and other allowances in the same period the related revenue is recorded. Provision for estimated sales returns and other allowances are generally made at a specific percentage based on historical experience, our management’s judgment, and any known factors that would significantly affect the allowance.

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

Inventories

Inventories are stated at the lower of cost or market value. Inventories are recorded at standard cost and adjusted to the approximate weighted-average cost at the end of the period. Market value represents replacement cost for raw materials, supplies and spare parts and net realizable value for finished goods and work in process. The Company assesses the impact of changing technology on its inventory on hand and writes off inventories that are considered obsolete. Ending inventories are evaluated for estimated excess quantities and obsolescence based on a demand forecast within a specific time horizon, which is generally 180 days or less. Estimated losses on scrap and slow-moving items are recognized in the allowance for losses.

- 8 -

Long-term Investments

Investments in companies wherein the Company exercises significant influence on the operating and financial policy decisions are accounted for using the equity method of accounting. The Company’s proportionate share in the net income or net loss of investee companies is recognized in the “investment income/loss recognized by equity method, net” account. When equity investments are made, the difference, if any, between the cost of investment and the Company’s proportionate share of the investee’s net equity is amortized using the straight-line method over five years and is also recorded in the “investment income/loss recognized by equity method, net” account. When an indication of significant impairment is identified, the impairment loss is charged to current income.

When the Company subscribes to additional investee shares at a percentage different from its existing equity interest, the resulting carrying amount of the investment in the investee differs from the amount of the Company’s proportionate share in the investee’s net equity. The Company records such difference as an adjustment to long-term investments with the corresponding amount charged or credited to capital surplus.

Investments in companies wherein the Company does not exercise significant influence are recorded at historical cost. Cash dividends are recognized as investment income in the year received but are accounted for as reductions in the carrying amount of the long-term investments if the dividends are received in the same year that the related investments are acquired. Stock dividends are recorded as an increase in the number of shares held and do not affect investment income or the carrying amount of the investment. The carrying amounts of investments whose fair market values are not readily ascertainable are reduced to reflect an other-than-temporary decline in their values, with the related impairment loss charged to income.

Investments in foreign mutual funds are stated at the lower of aggregate cost or net asset value. An allowance is recognized when the net asset value of the funds is lower than their cost, with the corresponding amount recorded as a reduction to shareholders’ equity. A reversal of the allowance will result from a subsequent recovery of the net asset value.

The costs of stocks and mutual funds sold are determined using the weighted-average method.

Investments in long-term bonds are stated at amortized cost. The discount or premium is amortized over the duration period using the interest method, and recorded as an adjustment to interest income.

If an investee company recognizes an unrealized loss on its long-term investment using the lower-of-cost-or-market method, the Company also recognizes a corresponding unrealized loss in proportion to its ownership percentage in the investee company and records the amount as a component of its shareholders’ equity.

Gains or losses on sales from the Company to investee companies accounted for using the equity method are deferred in proportion to the Company’s ownership percentage in the investee companies until realized through transactions with third parties. The entire amount of the gains or losses on sales to majority-owned subsidiaries is deferred until such gains or losses are realized through the subsequent sales of the related products to third parties.

Gains or losses on sales from investee companies to the Company are deferred in proportion to the Company’s ownership percentages in the investee companies until realized through transactions with third parties.

Gains and losses on sales by investee companies accounted for using the equity method are deferred in proportion to the Company’s ownership percentages in the investee companies until realized through transactions with third parties.

If an investee’s functional currency is a foreign currency, translation adjustments will result from the process of translating the investee’s financial statements into the reporting currency of the Company. Such adjustments are accumulated and reported as a separate component of shareholders’ equity.

Property, Plant and Equipment, Assets Leased to Others and Idle Assets

Property, plant and equipment and assets leased to others are stated at cost less accumulated depreciation. When an indication of significant impairment is identified, any excess of the carrying amount of an asset over its recoverable amount is recognized as a loss. If the recoverable amount increases in the future period, the subsequent reversal of the impairment loss would be recognized as a gain. However, the increased carrying amount of an asset due to a reversal of an impairment loss should not exceed the carrying amount that would have been determined (net of depreciation), had no impairment loss been recognized for the asset in prior years. Idle assets are stated at the lower of net realizable value or book value. Significant additions, renewals and betterments incurred during the construction period are capitalized. Maintenance and repairs are expensed in the period incurred. Interest expense incurred during the purchase and construction period is also capitalized.

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

Upon sale or disposal of property, plant and equipment, the related cost and accumulated depreciation are removed from the corresponding accounts, with any gain or loss credited or charged to non-operating income or expenses in the period of sale or disposal.

Goodwill

Goodwill represents the excess of the consideration paid for acquisition over the fair market value of identifiable net assets acquired and acquisition costs. Goodwill is amortized using the straight-line method over the estimated life of 10 years. If an event occurs or circumstances change that more likely than not reduce the fair value of goodwill below its carrying value, the impairement loss is charged to current income. Subsequent recovery in the fair value of the goodwill may not reverse the impairement loss previously recorded.

Deferred Charges

Deferred charges consist of technology license fees, software and system design costs and other charges. The amounts are amortized as follows: technology license fees — the shorter of the estimated life of the technology or the term of the technology transfer contract; software and system design costs and other charges — 3 years. When an indication of significant impairment is identified, any excess of the carrying amount of an asset over its recoverable amount is recognized as a loss. If the recoverable amount increases in the future period, the subsequent reversal of the impairment loss would be recognized as a gain. However, the increased carrying amount of an asset due to a reversal of an impairment loss should not exceed the carrying amount that would have been determined (net of amortization), had no impairment loss been recognized for the asset in prior years.

Pension Costs

The Company records net periodic pension costs on the basis of actuarial calculations. Unrecognized net transition obligation and unrecognized net gains or losses are amortized over 25 years.

Income Tax

The Company uses an inter-period tax allocation method for income tax. Deferred income tax assets and liabilities are recognized for the tax effects of temporary differences and unused tax credits. Valuation allowances are provided to the extent, if any, that it is more likely than not that deferred income tax assets will not be realized. A deferred tax asset or liability is classified as current or noncurrent in accordance with the classification of its related asset or liability. However, if a deferred tax asset or liability does not relate to an asset or liability in the financial statements, then it is classified as either current or noncurrent based on the expected length of time before it is realized or settled.

- 10 -

Any tax credits arising from the purchases of machinery, equipment and technology, research and development expenditures, personnel training, and investments in important technology-based enterprises are recognized using the flow-through method.

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

Income taxes on unappropriated earnings of 10% are expensed in the year of shareholder approval which is the year subsequent to the year the earnings are generated.

Stock-based Compensation

Employee stock option plans that are amended or have options granted on or after January 1, 2004 must be accounted for by the interpretations issued by the Accounting Research and Development Foundation. The Company adopted the intrinsic value method and any compensation cost determined using this method is charged to expense over the employee vesting period.

Treasury Stock

When the Company repurchases its outstanding common stock, the cost of the reacquired stock is recorded as treasury stock as a reduction to shareholders’ equity. When the Company retires treasury stock, the treasury stock account is reduced and the common stock as well as the capital surplus — additional paid-in capital are reversed in proportionate to the equity percentage of the retirement. When the book value of the treasury stock exceeds the sum of the par value and additional paid-in capital, the difference is charged to capital surplus - treasury stock and to retained earnings for any remaining amount. The Company’s stock held by its subsidiaries is also treated as treasury stock and reclassified from long-term investments to treasury stock. The cash dividends received by the subsidiaries from the Company are recorded under capital surplus — treasury stock.

Foreign-currency Transactions

Foreign currency transactions are recorded in New Taiwan dollars at the rates of exchange in effect when the transactions occur. Exchange gains or losses derived from foreign currency transactions or monetary assets and liabilities denominated in foreign currencies are recognized in current income. At the end of each period, assets and liabilities denominated in foreign currencies are revalued at the prevailing exchange rates with the resulting gains or losses recognized in current income.

Derivative Financial Instruments

The Company enters into foreign currency forward contracts to manage currency exposures on cash flow and on foreign-currency-denominated assets and liabilities. The contracts are recorded in New Taiwan dollars at the current rate of exchange of the contract date. The differences in the New Taiwan dollar amounts translated using the current rates and the amounts translated using the contracted forward rates on the contract date are amortized over the terms of the forward contracts using the straight-line method. At the end of each period, the receivables or payables arising from forward contracts are restated using the prevailing current rates at the balance sheet date with the resulting differences credited or charged to income. In addition, the receivables and payables related to the forward contracts of the same counter party are netted with the resulting amount presented as either an asset or a liability. Any resulting gain or loss upon settlement is credited or charged to income in the period of settlement.

- 11 -

	The Company enters into cross-currency swap contracts to manage currency exposures on foreign currency denominated assets and liabilities. The principal amount is recorded using the current rates at the contract date. The differences in the New Taiwan dollar amounts translated using the current rates and the amounts translated using the contracted rates on the contract date are amortized over the terms of the contracts using the straight-line method. At the end of each period, the receivables or payables arising from cross-currency swap contracts are restated using the prevailing current rate with the resulting differences credited or charged to income. In addition, the receivables and payables related to the contracts of the same counter party are netted with the resulting amount presented as either an asset or a liability. The difference in interest computed pursuant to the contracts on each settlement date or the balance sheet date is recorded as an adjustment to the interest income or expense associated with the hedged items. Any resulting gain or loss upon settlement is credited or charged to income in the period of settlement.
	The Company enters into interest rate swap contracts to manage exposures to changes in interest rates on existing assets or liabilities. These transactions are accounted for on an accrual basis, in which the cash settlement receivable or payable is recorded as an adjustment to interest income or expense associated with the hedged items.

14.	SHAREHOLDERS’ EQUITY
	The Company has issued a total of 668,351 thousand ADSs which are traded on the NYSE as of March 31, 2005. The number of common shares represented by the ADSs is 3,341,754 thousand shares (one ADS represents five common shares).
	Capital surplus can only be used to offset a deficit under the Company Law. However, the capital surplus generated from donations and the excess of the issue price over the par value of capital stock (including the stock issued for new capital, mergers, convertible bonds and the surplus from treasury stock transactions) may be appropriated as stock dividends once a year, which is restricted to a certain percentage of the paid in common stock of the Company.

-20-

As of March 31, 2005 and 2004, capital surplus consisted of the following:

	March 31
	2005		2004
From merger	$	24,003,546	$	24,132,297
Additional paid-in capital		23,077,544		23,172,550
From convertible bonds		9,360,424		9,410,632
From long-term investments		129,718		90,913
From treasury stock transactions		3,090		54,432
Donations		55		55
	$	56,574,377	$	56,860,879

The Company’s Articles of Incorporation as revised on December 21, 2004, provide that when allocating the net profits for each fiscal year, the Company shall first offset its losses in previous years and then set aside the following items accordingly:

a.	Legal capital reserve at 10% of the profits left over, until the accumulated legal capital reserve has equaled the Company’s total capital;
b.	Special capital reserve in accordance with relevant laws or regulations or as requested by the authorities in charge;
c.	Bonus to directors and supervisors and bonus to employees of the Company equal to 0.3% and not less than 1% of the remainder, respectively. The Company may issue stock bonuses to employees of an affiliated company meeting the conditions set by the Board of Directors or, by the person duly authorized by the Board of Directors;
d.	Any balance left over shall be allocated according to the resolution of the shareholders’ meeting.

Profits of this Company may be distributed by way of cash dividend and/or stock dividend. Since the Company is in a capital-intensive industry at the steady growth stage of its business, distribution of profits shall be made preferably by way of cash dividend. Distribution of profits may also be made by way of stock dividend; provided however, the ratio for stock dividend shall not exceed 50% of total distribution.

Any appropriations of net income are recorded in the financial statement in the year of shareholder approval.

The appropriation for legal capital reserve is made until the reserve equals the aggregate par value of the Company’s outstanding capital stock. The reserve can only be used to offset an accumulated deficit or be distributed as a stock dividend up to 50% of the reserve balance when the reserve balance has reached 50% of the aggregate par value of the issued capital stock of the Company.

A special capital reserve equivalent to the net debit balance of the other components of shareholder’s equity (for example, unrealized loss on long-term investments and cumulative translation adjustments, but excluding treasury stock) shall be made from unappropriated earnings pursuant to existing regulations promulgated by the R.O.C. Securities and Futures Bureau (SFB), formerly known as the Securities and Futures Commission. Any special reserve appropriated may be reversed to the extent that the net debit balance reverses.

-21-

The appropriations of earnings for 2004 and 2003 were approved in the board of directors’ meeting and the shareholders’ meeting on February 22, 2005 and May 11, 2004, respectively. The appropriations and dividends per share are as follows:

						Dividends Per Share
	Appropriation of Earnings					(NT$)
	For Fiscal		For Fiscal			For Fiscal		For Fiscal
	Year 2004		Year 2003			Year 2004		Year 2003
Legal reserve	$	8,820,201	$	4,725,870
Special reserve		2,226,427		(68,945	)
Employees’ profit sharing — in cash		3,086,215		681,628
Employees’ profit sharing — in stock		3,086,215		2,726,514
Cash dividends to preferred shareholders		—		184,493		$	—	$	0.35
Cash dividends to common shareholders		46,504,097		12,159,971			2.0		0.60
Stock dividends to common shareholders		11,626,024		28,373,267			0.5		1.41
Bonus to directors and supervisors — in cash		231,466		127,805
	$	75,580,645	$	48,910,603

The amount of the above appropriation of earnings for 2003 is consistent with the resolution of the meeting of the board of directors on February 17, 2004. However, the Company Law prescribes that TSMC, as a holder of treasury stock, shall not participate in the appropriation of earnings. Therefore, the actual cash dividend per share and stock dividend per share are slightly more than those in the aforementioned resolution. The appropriation of earnings for 2004 has not yet been resolved by the shareholders. If the above bonus to employee, directors and supervisors had been paid in cash and charged against income for 2004 and 2003, the after income tax basic earnings per share for the years ended December 31, 2004 and 2003 would have decreased from NT$3.97 to NT$3.70 and NT$2.33 to NT$2.15, respectively. The shares distributed as a bonus to employees represented 1.33% and 1.35% of the Company’s total outstanding common shares as of December 31, 2004 and 2003, respectively.

The above information about the appropriations of bonus to employees, directors and supervisors is available at Market Observation System website.

Under the Integrated Income Tax System that became effective on January 1, 1998, the R.O.C. resident shareholders are allowed a tax credit for their proportionate share of the income tax paid by the Company on earnings generated since January 1, 1998.

15.   STOCK-BASED COMPENSATION PLANS

The Company’s Employee Stock Option Plans under the 2004 Plan, 2003 Plan and 2002 Plan were approved by the SFB of the R.O.C. on January 6, 2005, October 29, 2003 and June 25, 2002, respectively.

The options of all the plans are valid for ten years and exercisable at certain percentages subsequent to the second anniversary of the grant date. Under the terms of the plans, the options are granted at an exercise price equal to the closing price of the Company’s common shares listed on the TSE on the grant date.

Under the 2003 Plan and the 2002 Plan, units that had never been granted, or had been granted and subsequently cancelled were expired as of March 31, 2005.

20.   SIGNIFICANT COMMITMENTS AND CONTINGENCIES

The significant commitments and contingencies of the Company as of March 31, 2005 are as follows:

a.	On June 20, 2004, the Company and Philips revised the Technical Cooperation Agreement, which was originally signed on May 12, 1997, with an effective date from January 1, 2004 for five years. Upon expiration, this amended Technical Cooperation Agreement will be terminated at the expiration date and will not be automatically renewed. Under this amended Technical Cooperation Agreement, the Company will pay Philips royalties based on a fixed amounts mutually agreed-on, rather than under certain percentage of the Company’s annual net sales. The Company and Philips agree to cross license the patents owned by each party. The Company also obtained through Philips a number of patent cross licenses.
b.	Under a technical cooperation agreement with ITRI, the Company shall reserve and allocate up to 35% of certain of its production capacity for use by the Ministry of Economic Affairs (MOEA) or any other party designated by the MOEA. The term of this agreement is for five years beginning January 1, 1987 and is automatically renewed for successive periods of five years unless otherwise terminated by either party with one year prior notice. The agreement was automatically renewed in 1992 and 1997 and on January 1, 2002.
c.	On October 28, 1992, the Company entered into a letter agreement with Philips under which Philips has an option on up to 30% of the Company’s capacity as agreed in the agreement on most favored terms and conditions for similar orders, as long as Philips’ and its affiliates’ shareholding in the Company remains at 24.8% or higher. As of March 12, 2005, Philips’ and its affiliates’ shareholding in the Company is 18.98%.
d.	Under several foundry agreements, the Company shall reserve a portion of its production capacity for certain major customers that have guarantee deposits with the Company. As of March 31, 2005, the Company had a total of US$11,645 thousand of guarantee deposits.
e.	Under a Shareholders Agreement entered into with Philips and EDB Investments Pte Ltd. on March 30, 1999, the parties formed a joint venture company, SSMC, for the purpose of constructing an integrated circuit foundry in Singapore. As of March 31, 2005, the Company’s equity interest in SSMC was 32%. The Company and Philips committed to buy specific percentages of the production capacity of SSMC. The Company and Philips are required, in the aggregate, to purchase up to 70% of SSMC’s full capacity, but the Company along is not required to purchase more than 28% of the annual installed capacity. If any party defaults on the commitment and the capacity utilization of SSMC falls below a specific percentage of its total capacity, the defaulting party is required to compensate SSMC for all related unavoidable costs.
f.	The Company provides technical services to SSMC under a Technical Cooperation Agreement (the Agreement) entered into on May 12, 1999. The Company receives compensation for such services computed at a specific percentage of net selling price of certain products sold by SSMC. The Agreement shall remain in force for ten years and may be automatically renewed for successive periods of five years each unless pre-terminated by either party under certain conditions.
g.	Under a Technology Transfer Agreement (TTA) with National Semiconductor Corporation (National) entered into on June 27, 2000, the Company shall receive payments for the licensing of certain technology to National. The agreement was to remain in force for ten years and could be automatically renewed for successive periods of two years thereafter unless either party gives notice for early termination under certain conditions. In January 2003, the Company and National entered into a Termination Agreement whereby the TTA was terminated for convenience. Under the Termination Agreement, the Company will be relieved of any further obligation to transfer any additional technology. In addition, the Company granted National an option to request the transfer of certain technologies under the same terms and conditions as the terminated TTA. The option will expire in January 2008.

-28-

h.	Beginning in 2001, the Company entered into several licensing arrangements for certain semiconductor patents. The terms of the contracts range from five to ten years with payments to be made in the form of royalties over the term of the related contracts. The Company has recorded the related amounts as a liability with the corresponding amounts recorded as deferred charges which are amortized and charged to cost of sales on a straight-line basis over the estimated life of the technology or the term of the contract, whichever is shorter.
i.	In November 2002, the Company entered into an Amended and Restated Joint Technology Cooperation Agreement with Philips, Freescale Semiconductor, Inc. and STMicroelectronics to jointly develop 90-nm to 65-nm advanced CMOS Logic and e-DRAM technologies. The Company also agreed to align 0.12 micron CMOS Logic technology to enhance its foundry business opportunities. The Company will contribute process technologies and share a portion of the costs associated with this joint development project.
j.	In December 2003, the Company entered into a Technology Development and License Agreement with Freescale Semiconductor, Inc. to jointly develop 65-nm SOI (silicon on insulator) technology. The Company will also license related 90-nm SOI technology from Freescale Semiconductor, Inc. Any intellectual properties arising out of the co-development project shall be jointly owned by the parties. In accordance with the agreement, the Company will pay royalties to Freescale Semiconductor, Inc. and will share a portion of the costs associated with the joint development project.
k.	The Company provides a technology transfer to VIS under a Manufacturing License and Technology Transfer Agreement entered into in August 2004. The Company receives compensation for such technology transfer in the form of royalty payments from VIS computed at specific percentages of net selling price of certain products sold by VIS. VIS agreed to reserve its certain capacity to manufacture for the Company certain products at prior as agreed by the parties.
l.	Amounts available under unused letters of credit as of March 31, 2005 were NT$6,480 thousand and US$204 thousand.
m.	The Company provided guarantees on loans amounting to US$60,000 thousand and US$40,000 thousand for TSMC Development, Inc. (TSMC Development) and TSMC-North America, respectively.
n.	TSMC, TSMC-North America and WaferTech filed a series of lawsuits in late 2003 and 2004 in both state and federal courts in California and with the U.S. International Trade Commission against Semiconductor Manufacturing International Corporation (“SMIC”), SMIC (Shanghai) and SMIC Americas. The lawsuits alleged that SMIC companies infringed multiple TSMC patents and misappropriated TSMC’s trade secrets. These suits have been settled out of court on January 30, 2005. As part of the settlement, SMIC will pay TSMC US$175 million over six years to resolve TSMC’s patent infringement and trade secret claims.

	Outstanding contracts as of March 31, 2004 were as follows:

		Contract
		Amount
Contract Date	Period	(In Thousands)
Jul. 1999	Jul. 1999 to Jun. 2004		US$    2,857
Sep. 2003	Sep. 2003 to Dec. 2005	NT$500,000
Oct. 2003	Oct. 2003 to Dec. 2005	NT$500,000
Oct. 2003	Oct. 2003 to Dec. 2005	NT$500,000

Nov. 2003	Nov. 2003 to Dec. 2005	NT$500,000

d)   Transaction risk

i)	Credit risk. Credit risk represents the positive net settlement amount of those contracts with positive fair values at the balance sheet date. The positive net settlement amount represents the loss incurred by the Company if the counter-parties breached the contracts. The banks, which are the counter-parties to the foregoing derivative financial instruments, are reputable financial institutions. Management believes its exposure related to the potential default by those counter-parties is low.
ii)	Market price risk. All derivative financial instruments are intended as hedges for fluctuations in foreign exchange rates and interest rates. Gains or losses from these hedging instruments are likely to be offset by gains or losses from the hedged items. Interest rate risks are also controlled as the expected cost of capital is fixed. Thus, market price risks are believed to below.
iii)	Cash flow risk and the amount and period of future cash needs.
	As of March 31, 2005, the Company’s future cash needs for outstanding forward exchange contracts and cross currency swap contracts were as follows:

	Inflow		Outflow
Term	(In Thousands)		(In Thousands)
Within one year	NT$65,770,604		NT$1,261,940
	US$	40,000	US$	2,103,000

-31-

     The Company has sufficient operating capital to meet the above cash needs. In addition, there will be corresponding cash inflow for the cash outflow. Therefore, the cash flow risk is low.

2)   Fair values of financial instruments were as follows:

	March 31, 2005						March 31, 2004
	Carrying						Carrying
	Amount			Fair Value			Amount		Fair Value
Non-derivative financial instruments
Assets
Short-term investments	$	51,638,170		$	51,638,170		$	19,829,168	$	19,905,368
Long-term investments (securities with market price)		32,746,088			36,480,721			4,375,675		10,963,129
Liabilities
Bonds payable (including current portion)		30,000,000			30,522,754			35,000,000		35,758,784
Derivative financial instruments
Forward exchange contracts (sell)		(243,945	)		(205,815	)		900,111		961,743
Forward exchange contracts (buy)		(1,188	)		(1,541	)		6,771		318
Cross currency swap contracts		(306,246	)		(331,511	)		—		—
Interest rate swap contracts		—			—			13,954		36,038

The above financial instruments do not include cash and cash equivalents, receivables, other financial assets, payables, and payable to contractors and equipment suppliers. The carrying amounts of the aforementioned financial instruments reported in the balance sheet approximate their fair values.

The above financial instruments also exclude refundable deposits, guarantee deposits, long-term investments that do not have quoted market prices as well as other long-term payables. The future cash inflow and outflow of the deposits approximate their fair values. Some of long-term investments do not have quoted market prices; therefore, fair values for those long-term investments are not shown above. The fair value of other long-term payables is determined using the discounted value of expected cash flows, which approximates the carrying value.

Fair values of financial instruments were determined as follows:

a)	Fair value of short-term and publicly traded long-term investments is based on quoted market prices.
b)	The fair value of bonds payable is the quoted market value.
c)	Fair value of derivative financial instruments is the amount receivable from or payable to the counter-party if the contracts were terminated on the balance sheet date.

The fair values of some financial and non-financial instruments were not included in the fair values disclosed above. Accordingly, the sum of the fair values of the financial instruments listed above does not represent the fair value of the Company as a whole.
