REPORT OF INDEPENDENT AUDITORS

English Translation of a Report Originally Issued in Chinese

To United Microelectronics Corporation

We have audited the accompanying balance sheets of United Microelectronics Corporation as of June 30, 2007 and 2006, and the related statements of income, statements of changes in stockholders’ equity, and cash flows for the six-month periods ended June 30, 2007 and 2006. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. As described in Note 4(8) to the financial statements, certain long-term investments were accounted for under the equity method based on financial statements as of June 30, 2007 and 2006 of the investees, which were audited by other auditors. Our opinion insofar as it relates to the investment income amounting to NT$470 million and NT$499 million for the six-month periods ended June 30, 2007 and 2006, respectively, and the related long-term investment balances of NT$7,049 million and NT$5,706 million as of June 30, 2007 and 2006, respectively, is based solely on the reports of the other auditors.

We conducted our audits in accordance with auditing standards generally accepted in the Republic of China and “Guidelines for Certified Public Accountants’ Examination and Reports on Financial Statements”, which require that we plan and perform the audit to obtain reasonable assurance about whether the 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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits and the reports of the other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the reports of other auditors, the financial statements referred to above present fairly, in all material respects, the financial position of United Microelectronics Corporation as of June 30, 2007 and 2006, and the results of its operations and its cash flows for the six-month periods ended June 30, 2007 and 2006, in conformity with the “Business Entity Accounting Law”, the “Regulation on Business Entity Accounting Handling”, the “Guidelines Governing the Preparation of Financial Reports by Securities Issuers” and accounting principles generally accepted in the Republic of China.

As described in Note 3 to the financial statements, effective from January 1, 2006, United Microelectronics Corporation has adopted the ROC Statement of Financial Accounting Standards No. 34, “Financial Instruments: Recognition and Measurement” and No. 36, “Financial Instruments: Disclosure and Presentation” to account for the financial instruments.

As described in Note 3 to the financial statements, effective from January 1, 2006, goodwill is no longer to be amortized.

We have also audited the consolidated financial statements of United Microelectronics Corporation as of and for the six-month periods ended June 30, 2007 and 2006, and have expressed an unqualified opinion with explanatory paragraph on such financial statements.

NOTES TO FINANCIAL STATEMENTS

June 30, 2007 and 2006

(Expressed in Thousands of New Taiwan Dollars unless Otherwise Specified)

1.	HISTORY AND ORGANIZATION

United Microelectronics Corporation (the Company) was incorporated in May 1980 and commenced operations in April 1982. The Company is a full service semiconductor wafer foundry, and provides a variety of services to satisfy customer needs. These services include intellectual property, embedded IC design, design verification, mask tooling, wafer fabrication, and testing. The Company’s common shares were publicly listed on the Taiwan Stock Exchange (TSE) in July 1985 and its American Depositary Shares (ADSs) were listed on the New York Stock Exchange (NYSE) in September 2000.

The numbers of employees as of June 30, 2007 and 2006 were 13,528 and 12,448, respectively.

2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The financial statements were prepared in conformity with the “Business Entity Accounting Law”, “Regulation on Business Entity Accounting Handling”, “Guidelines Governing the Preparation of Financial Reports by Securities Issuers” and accounting principles generally accepted in the Republic of China (R.O.C.).

Summary of significant accounting policies is as follows:

Use of Estimates

The preparation of the Company’s Financial Statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that will affect the amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reported period. Actual results may differ from those estimates.

Foreign Currency Transactions

Transactions denominated in foreign currencies are remeasured into the local functional currencies and recorded based on the exchange rates prevailing at the transaction dates. Monetary assets and liabilities denominated in foreign currencies are remeasured into the local functional currencies at the exchange rates prevailing at the balance sheet date, with the related exchange gains or losses included in the statements of income. Translation gains or losses from investments in foreign entities are recognized as cumulative translation adjustment in stockholders’ equity.

Non-monetary assets and liabilities denominated in foreign currencies that are reported at fair value with changes in fair value charged to the statements of income, are remeasured at the exchange rate at the balance sheet date, with related exchange gains or losses recorded in the statements of income. Non-monetary assets and liabilities denominated in foreign currencies that are reported at fair value with changes in fair value charged to stockholders’ equity, are remeasured at the exchange rate at the balance sheet date, with related exchange gains or losses recorded as adjustment items to stockholders’ equity. Non-monetary assets and liabilities denominated in foreign currencies and reported at cost are remeasured at historical exchange rates.

Translation of Foreign Currency Financial Statements

The financial statements of the Company’s Singapore branch (the Branch) are translated into New Taiwan Dollars using the spot rates as of each financial statement date for asset and liability accounts and average exchange rates for profit and loss accounts. The cumulative translation effects from the Branch using functional currencies other than New Taiwan Dollars are included in the cumulative translation adjustment in stockholders’ equity.

Cash Equivalents

Cash equivalents are short-term, highly liquid investments that are readily convertible to known amounts of cash and with maturity dates that do not present significant risks on changes in value resulting from changes in interest rates, including commercial paper with original maturities of three months or less.

Financial Instruments

In accordance with ROC Statement of Financial Accounting Standard (SFAS) No. 34, “Financial Instruments: Recognition and Measurement” and the “Guidelines Governing the Preparation of Financial Reports by Securities Issuers”, financial assets are classified as either financial assets at fair value through profit or loss, held-to-maturity financial assets, financial assets measured at cost, or available-for-sale financial assets. Financial liabilities are recorded at fair value through profit or loss.

The Company accounts for purchase or sale of financial instruments as of the trade date, which is the date the Company commits to purchasing or selling the asset or liability. Financial assets and financial liabilities are initially recognized at fair value plus acquisition or issuance costs.

Financial instruments at fair value through profit or loss

Financial instruments held for short-term sale or repurchase purposes and derivative financial instruments not qualified for hedge accounting are classified as financial assets or liabilities at fair value through profit or loss.

This category of financial instruments is measured at fair value and changes in fair value are recognized in the statements of income. Stock of listed companies, convertible bonds, and close-end funds are measured at closing prices as of the balance sheet date. Open-end funds are measured at the unit price of the net assets as of the balance sheet date. The fair value of derivative financial instruments is determined by using valuation techniques commonly used by market participants.

Held-to-maturity financial assets

Non-derivative financial assets with fixed or determinable payments and fixed maturity are classified as held-to-maturity financial assets if the Company has both the positive intention and ability to hold the financial assets to maturity. Investments intended to be held to maturity are measured at amortized cost.

The Company recognizes an impairment loss if objective evidence of impairment loss exists. However, the impairment loss may be reversed if the value of asset recovers subsequently and the Company concludes the recovery is related to improvements in events or factors that originally caused the impairment loss. The new cost basis as a result of the reversal cannot exceed the amortized cost prior to the impairment.

Financial assets measured at cost

Unlisted stock, funds, and other securities without reliable market prices are measured at cost. When objective evidence of impairment exists, the Company recognizes an impairment loss, which cannot be reversed in subsequent periods.

Available-for-sale financial assets

Available-for-sale financial assets are non-derivative financial instruments not classified as financial assets at fair value through profit or loss, held-to-maturity financial assets, loans and receivables. Subsequent measurement is calculated at fair value. Investments in listed companies are measured at closing prices as of the balance sheet date. Any gain or loss arising from the change in fair value, excluding impairment loss and exchange gain or loss arising from monetary financial assets denominated in foreign currencies, is recognized as an adjustment to stockholders’ equity until such investment is reclassified or disposed of, upon which the cumulative gain or loss previously charged to stockholders’ equity will be recorded in the statement of income.

The Company recognizes an impairment loss when objective evidence of impairment exists. Any reduction in the impairment loss of equity investments in subsequent periods will be recognized as an adjustment to stockholders’ equity. The impairment loss of a debt security may be reversed and recognized in the current period’s statement of income if the security recovers and the Company concludes the recovery is clearly related to improvements in the factors or events that originally caused the impairment.

Allowance for Doubtful Accounts

An allowance for doubtful accounts is provided based on management’s judgment of the collectibility and aging analysis of accounts and other receivables.

Inventories

Inventories are accounted for on a perpetual basis. Raw materials are recorded at actual purchase costs, while the work in process and finished goods are recorded at standard costs and adjusted to actual costs using the weighted-average method at the end of each month. Inventories are stated individually by category at the lower of aggregate cost or market value as of the balance sheet date. The market values of raw materials and supplies are determined on the basis of replacement cost while the market values of work in process and finished goods are determined by net realizable values. An allowance for loss on decline in market value or obsolescence is provided, when necessary.

Long-term Investments Accounted for Under the Equity Method

Long-term investments are initially recorded at acquisition cost. Investments acquired by the contribution of technological know-how are credited to deferred credits among affiliates, which will be amortized to income over a period of 5 years.

Investments in which the Company has ownership of at least 20% or exercises significant influence on operating decisions are accounted for under the equity method. Prior to January 1, 2006, the difference of the acquisition cost and the underlying equity in the investee’s net assets as of acquisition date was amortized over 5 years; however, effective January 1, 2006, goodwill arising from new acquisitions is analyzed and accounted for under the ROC SFAS No. 25, “Business Combination – Accounting Treatment under Purchase Method”, where goodwill is no longer to be amortized.

The change in the Company’s proportionate share in the net assets of an investee resulting from its acquisition of additional stock issued by the investee at a rate not proportionate to its existing equity ownership is charged to the additional paid-in capital and long-term investments accounts.

Unrealized intercompany gains and losses arising from sales from the Company to equity method investees are eliminated in proportion to the Company’s ownership percentage at end of period until realized through transactions with third parties. Intercompany gains and losses arising from transactions between the Company and majority-owned (above 50%) subsidiaries are eliminated entirely until realized through transactions with third parties.

Unrealized intercompany gains and losses due to sales from equity method investees to the Company are eliminated in proportion to the Company’s weighted-average ownership percentage of the investee until realized through transactions with third parties.

Unrealized intercompany gains and losses arising from transactions between two equity method investees are eliminated in proportion to the Company’s multiplied weighted-average ownership percentage with the investees until realized through transactions with third parties. Those intercompany gains and losses arising from transactions between two majority-owned subsidiaries are eliminated in proportion to the Company’s weighted-average ownership percentage in the subsidiary that incurred the gain or loss.

If the recoverable amount of investees accounted for under the equity method is less than its carrying amount, the difference is to be recognized as impairment loss in the current period.

The total value of an investment and related receivables cannot be negative. If, after the investment loss is recognized, the net book value of the investment is less than zero, the investment is reclassified to other liabilities—others on the balance sheet.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Interest incurred on loans used to finance the construction of property, plant and equipment is capitalized and depreciated accordingly. Maintenance and repairs are charged to expense as incurred. Significant renewals and improvements are treated as capital expenditures and are depreciated over their estimated useful lives. When property, plant and equipment are disposed, their original cost and accumulated depreciation are written off and the related gain or loss is classified as non-operating income or expense. Idle assets are classified as other assets at the lower of net book or net realizable value, with the difference charged to non-operating expenses.

Depreciation is recognized on a straight-line basis using the estimated economic life of the assets less salvage value, if any. The estimated economic life of the property, plant and equipment is as follows: buildings – 20 to 55 years; machinery and equipment – 5 years; transportation equipment – 5 years; furniture and fixtures – 5 years.

Intangible Assets

Effective January 1, 2006, goodwill generated from business combinations is no longer subject to amortization.

Technological know-how is stated at cost and amortized over its estimated economic life using the straight-line method.

An impairment loss will be recognized when the decreases in fair value of intangible assets are other than temporary. The book value after recognizing the impairment loss is recorded as the new cost.

Deferred Charges

Deferred charges are stated at cost and amortized on a straight-line basis as follows: intellectual property license fees - select the shorter term of contract or estimated economic life of the related technology; and software - 3 years.

Prior to December 31, 2005, the issuance costs of convertible and exchangeable bonds were classified as deferred charges and amortized over the life of the bonds. Effective January 1, 2006, the unamortized amounts as of December 31, 2005 were reclassified as a bond discount and recorded as a deduction to bonds payable. The amounts are amortized using the effective interest method over the remaining life of the bonds. If the difference between the straight-line method and the effective interest method is immaterial, the amortization of the bond discount may be amortized using the straight-line method and recorded as the adjustment of interest expenses.

Convertible and Exchangeable Bonds

The excess of the stated redemption price over par value is accrued as interest payable and expensed over the redemption period using the effective interest method.

When convertible bondholders exercise their conversion rights, the book value of the bonds is credited to common stock at an amount equal to the par value of the common stock with the excess credited to additional paid-in capital. No gain or loss is recognized on bond conversion.

When exchangeable bondholders exercise their right to exchange their bonds for reference shares, the book value of the bonds is offset against the book value of the investments in reference shares and the related stockholders’ equity accounts, with the difference recognized as a gain or loss on disposal of investments.

In accordance with ROC SFAS No. 34, “Financial Instruments: Recognition and Measurement,” effective as of January 1, 2006, since the economic and risk characteristics of the embedded derivative instrument and the host contract are not clearly and closely related, derivative financial instruments embedded in exchangeable bonds shall be bifurcated and accounted as financial liabilities at fair value through profit or loss.

Pension Plan

All regular employees are entitled to a defined benefit pension plan that is managed by an independently administered pension fund committee. Fund assets are deposited in the committee’s name in the Bank of Taiwan and hence, not associated with the Company. Therefore, fund assets are not to be included in the Company’s financial statements. Pension benefits for employees of the Branch are provided in accordance with the local regulations.

The Labor Pension Act of the ROC (the Act), which adopts a defined contribution plan, became effective on July 1, 2005. Employees subject to the Labor Standards Law, a defined benefit plan, were allowed to choose to either elect the pension calculation under the Act or continue to be subject to the pension calculation under the Labor Standards Law. Those employees that elected to be subject to the Act will have their seniority achieved under the Labor Standards Law retained upon election of the Act, and the Company will make monthly contributions of no less than 6% of these employees’ monthly wages to the employees’ individual pension accounts.

The accounting for the Company’s pension liability is computed in accordance with ROC SFAS No.18. Net pension costs of the defined benefit plan are recorded based on an actuarial valuation. Pension cost components such as service cost, interest cost, expected return on plan assets, the amortization of net obligation at transition, pension gain or loss, and prior service cost, are all taken into consideration by the actuary. The Company recognizes expenses from the defined contribution pension plan in the period in which the contribution becomes due.

Employee Stock Option Plan

The Company uses intrinsic value method to recognize compensation cost for its employee stock options issued since January 1, 2004. Under the intrinsic value method, the Company recognizes the difference between the market price of the stock on date of grant and the exercise price of its employee stock option as compensation cost. The Company also discloses pro forma net income and earnings per share under the fair value method for options granted since January 1, 2004.

Treasury Stock

The Company adopted ROC SFAS No. 30, “Accounting for Treasury Stocks” which requires that treasury stock held by the Company to 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 additional paid-in capital. The Company’s stock held by its subsidiaries is also treated as treasury stock. Cash dividends received by subsidiaries from the Company are recorded as additional paid-in capital - treasury stock transactions.

Revenue Recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, the product or service has been delivered, the seller’s price to the buyer is fixed or determinable and collectibility is reasonably assured. Most of the Company’s sales transactions have shipping terms of Free on Board (FOB) or Free Carrier (FCA) shipment in which title and the risk of loss or damage is transferred to the customer upon delivery of the product to a carrier approved by the customer.

Allowance for sales returns and discounts are estimated taking into consideration customer complaints, historical experiences, management judgment and any other known factors that might significantly affect collectibility. Such allowances are recorded in the same period in which sales are made.

Research and Development Expenditures

Research and development expenditures are charged to expenses as incurred.

Capital Expenditures Versus Operating Expenditures

An expenditure is capitalized when it is probable that the Company will receive future economic benefits associated with the expenditure. Otherwise, the expenditure is expensed as incurred.

Income Tax

The Company adopted ROC SFAS No. 22, “Accounting for Income Taxes” for inter-period and intra-period income tax allocation. The provision for income taxes includes deferred income tax assets and liabilities that are a result of temporary differences between carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, loss carry-forward and investment tax credits. A valuation allowance on deferred income tax assets is provided to the extent that it is more likely than not that the tax benefits 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 reversal date of the temporary difference.

According to ROC SFAS No. 12, “Accounting for Income Tax Credits”, the Company recognizes the tax benefit from the purchase of equipment and technology, research and development expenditure, employee training, and certain equity investment by the flow-through method.

Income tax (10%) on unappropriated earnings is recorded as expense in the year in which the shareholders have resolved that the earnings shall be retained.

The Income Basic Tax Act of the R.O.C. (the IBTA) became effective on January 1, 2006. Set up by the Executive Yuan, the IBTA is a supplemental 10% tax that is payable if the income tax payable determined by the ROC Income Tax Act is below the minimum amount as prescribed by the IBTA. The IBTA is calculated based on taxable income as defined by the IBTA, which includes most income that is exempted from income tax under various legislations. The impact of the IBTA has been considered in the Company’s income tax for the current reporting period.

Earnings per Share

Earnings per share is computed according to ROC SFAS No. 24, “Earnings Per Share.” Basic earnings per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the current reporting period. Diluted earnings per share is computed by taking basic earnings per share into consideration plus additional common shares that would have been outstanding if the dilutive share equivalents had been issued. Net income (loss) is also adjusted for interest and other income or expenses derived from any underlying dilutive share equivalents. The weighted-average of outstanding shares is adjusted retroactively for stock dividends and bonus share issues.

Asset Impairment

Pursuant to ROC SFAS No. 35, the Company assesses indicators of impairment for all its assets (except for goodwill) within the scope of the standard at each balance sheet date. If impairment is indicated, the Company compares the asset’s carrying amount with the recoverable amount of the assets or the cash-generating unit (CGU) associated with the asset and writes down the carrying amount to the recoverable amount where applicable. The recoverable amount is defined as the higher of fair value less the costs to sell, and the values in use. For previously recognized losses, the Company assesses at the balance sheet date any indication that the impairment loss no longer exists or may have diminished. If there is any such indication, the Company recalculates the recoverable amount of the asset, and if the recoverable amount has increased as a result of the increase in the estimated service potential of the assets, the Company reverses the impairment loss so that the resulting carrying amount of the asset does not exceed the amount (net of amortization or depreciation) that would otherwise result had no impairment loss been recognized for the assets in prior years.

In addition, a goodwill-allocated CGU or group of CGUs is tested for impairment each year, regardless of whether impairment is indicated. If an impairment test reveals that the carrying amount, including goodwill, of CGU or group of CGUs is greater than its recoverable amount, there is an impairment loss. The loss is first recorded against the CGU’s goodwill, with any remaining loss allocated to other assets on a pro rata basis proportionate to their carrying amounts. The write-down of goodwill cannot be reversed in subsequent periods under any circumstances.

Impairment losses and reversals are classified as non-operating loss and income, respectively.

3.	ACCOUNTING CHANGES

Goodwill

The Company adopted the amendments to ROC SFAS No. 1, “Conceptual Framework of Financial Accounting and Preparation of Financial Statements,” SFAS No. 5, “Long-Term Investments in Equity Securities,” and SFAS No. 25, “Business Combinations - Accounting Treatment under Purchase Method,” all of which have discontinued the amortization of goodwill effective January 1, 2006. As a result of adopting the revised SFAS No.1, revised SFAS No.5 and revised SFAS No.25 on January 1, 2006, the Company’s total assets as of June 30, 2006 are NT$429 million higher than if it had continued to account for goodwill under the prior year’s requirements. The net income and earnings per share for the six-month period ended June 30, 2006, are NT$429 million and NT$0.02 higher, respectively, than if the Company had continued to account for goodwill under the prior year’s requirements.

Financial Instruments

(1)

The Company adopted ROC SFAS No. 34, “Financial Instruments: Recognition and Measurement” and SFAS No. 36, “Financial Instruments: Disclosure and Presentation” to account for the financial instruments effective January 1, 2006.

RETAINED EARNINGS AND DIVIDEND POLICIES

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

Payment of all taxes and dues;

Offset prior years’ operation losses;

Set aside 10% of the remaining amount after deducting items (a) and (b) as a legal reserve;

Set aside 0.1% of the remaining amount after deducting items (a), (b), and (c) as directors’ and supervisors’ remuneration; and

After deducting items (a), (b), and (c) above from the current year’s earnings, no less than 5% of the remaining amount together with the prior years’ unappropriated earnings is to be allocated as employees’ bonus, which will be settled through issuance of new shares of the Company, or cash. Employees of the Company’s subsidiaries, meeting certain requirements determined by the board of directors, are also eligible for the employees’ bonus.

The distribution of the remaining portion, if any, will be recommended by the board of directors and subject to shareholders’ approval.

The policy for dividend distribution should reflect factors such as the current and future investment environment, fund requirements, domestic and international competition and capital budgets; as well as the benefit of shareholders, share bonus equilibrium, and long-term financial planning. The board of directors shall make the distribution proposal annually and present it at the shareholders’ meeting. The Company’s Articles of Incorporation further provide that no more than 80% of the dividends to shareholders, if any, may be paid in the form of stock dividends. Accordingly, at least 20% of the dividends must be paid in the form of cash.

The distributions of retained earnings for the years 2006 and 2005 were approved through the shareholders’ meetings held on June 11, 2007 and June 12, 2006, respectively. The details of distribution are as follows:


	2006		2005

Employees’ bonus – Stock Dividend (NTD thousands)		—		458,455
Directors’ and Supervisors’ remuneration (NTD thousands)		15,494		6,324

Pursuant to Article 41 of the Securities and Exchange Law of the R.O.C., a special reserve is set aside from the current net income and unappropriated earnings for items that are accounted for as deductions to stockholders’ equity such as unrealized loss on long-term investment and cumulative translation adjustments. However, there are the following exceptions for the Company’s investees’ unrealized loss on long-term investments arising from the merger, which was recognized by the Company in proportion to the Company’s ownership percentage:

According to the explanatory letter No. 101801 of the Securities and Futures Commission (SFC), if the Company recognizes the investees’ additional paid-in capital–excess from the merger in proportion to the ownership percentage, then the special reserve is exempted for the amount originated from the acquisition of the long-term investments.

If the Company and its investees transfer a portion of the additional paid-in capital to increase capital, a special reserve equal to the amount of the transfer shall be provided according to the explanatory letter No. 101801-1 of the SFC.

In accordance with the explanatory letter No. 170010 of the SFC applicable to listed companies, in the case where the market value of the Company’s stock held by its subsidiaries at period-end is lower than the book value, a special reserve shall be provided in the Company’s accounts in proportion to its ownership percentage.

For the 2005 appropriations approved by the shareholders’ meeting on June 12, 2006, unrealized loss on long-term investments exempted from the provision of special reserve pursuant to the above regulations amounted to NT$18,208 million.

Tsao, released a public statement, explaining that its assistance to Hejian Technology Corp. (Hejian) did not involve any investment or technology transfer. Furthermore, from the very beginning there was a verbal indication that, at the proper time, the Company would be compensated appropriately for its assistance, and circumstances permitting, at some time in the future, it will push through the merger between two companies. However, no promise was made by the Company and no written agreement was made and executed. Upon the Company’s request to materialize the said verbal indication by compensating in the form of either cash or equity, the Chairman of the holding company of Hejian offered 15% of the approximately 700 million outstanding shares of the holding company of Hejian in return for the Company’s past assistance and for continued assistance in the future.

Immediately after the Company had received such offer, it filed an application with the Investment Commission of the Ministry of Economic Affairs on March 18, 2005 (Ref. No. 94-Lian-Tung-Tzu-0222), for their executive guidance for the successful transfer of said shares to the Company. The shareholders meeting dated June 13, 2005 resolved that to the extent permitted by law the Company shall try to get the 15% of the outstanding shares offered by the holding company of Hejian as an asset of the Company. The holding company of Hejian offered 106 million shares of its outstanding common shares in return for the Company’s assistance. The holding company of Hejian has put all such shares in escrow. The Company was informed of such escrow on August 4, 2006. The subscription price per share of the holding company of Hejian in the last offering was US$1.1. Therefore, the total market value of the said shares is worth more than US$110 million. However, the Company may not acquire the ownership of nor exercise the rights of the said shares with any potential stock dividend or cash dividend distributed in the future until the ROC laws and regulations allow the Company to acquire and exercise. In the event that any stock dividend or cash dividend is distributed, the Company’s stake in the holding company of Hejian will accumulate accordingly.

In April 2005, the Company’s former Chairman Mr. Robert H.C. Tsao was personally fined with in the aggregate amount of NT$3 million by the Financial Supervisory Commission, Executive Yuan, R.O.C. (ROC FSC) for failure to disclose material information relating to Hejian in accordance with applicable rules. As a result of the imposition of the fines by the ROC FSC, the Company was also fined in the amount of NT$30,000 by Taiwan Stock Exchange (TSE) for the alleged non-compliance with the disclosure rules in relation to the material information. The Company and its former Chairman Mr. Robert H.C. Tsao have filed for administrative appeal and reconsideration with the Executive Yuan, R.O.C. and TSE, respectively. Mr. Robert H.C. Tsao’s administrative appeal was dismissed by the Execution Yuan, R.O.C. on February 21, 2006 and the ROC FSC transferred the case against Mr. Robert H.C. Tsao to the Administrative Enforcement Agency for enforcement of the fine. Mr. Robert H.C. Tsao has filed an administrative action against the ROC FSC with Taipei High Administrative Court on April 14, 2006. As of June 30, 2007, the result of such reconsideration and administrative action has not been finalized. The case is being processed in Taipei High Administrative Court.

For the Company’s assistance to Hejian Technology Corp., the Company’s former Chairman Mr. Robert H.C. Tsao, former Vice Chairman Mr. John Hsuan, and Mr. Duen-Chian Cheng, the General Manager of Fortune Venture Capital Corp., which is 99.99% owned by the Company, were indicted for violating the Business Entity Accounting Law and breach of trust under the Criminal Law by Hsinchu District Court’s Prosecutor’s Office on January 9, 2006. Mr. Robert H.C. Tsao and Mr. John Hsuan had officially resigned from their positions of the Company’s Chairman, Vice Chairman and directors prior to the announcement of the prosecution; for this reason, at the time of the prosecution, Mr. Robert H.C. Tsao and Mr. John Hsuan no longer served as the Company’s directors and had not executed their duties as the Company’s Chairman and Vice Chairman. In the future, if a guilty judgment is pronounced by the court, such consequences would be Mr. Robert H.C. Tsao, Mr. John Hsuan and Mr. Duen-Chian Cheng’s personal concerns only; the Company would not be subject to indictment regarding this case.

On February 15, 2006, the Company was fined in the amount of NT$5 million for unauthorized investment activities in Mainland China, implicating violation of Article 35 of the Act “Governing Relations Between Peoples of the Taiwan Area and the Mainland Area” by the R.O.C. Ministry of Economic Affairs (MOEA). However, as the Company believes it was illegally and improperly fined, the Company had filed an administrative appeal against MOEA to the Executive Yuan on March 16, 2006. On October 19, 2006, Executive Yuan denied the administrative appeal filed by UMC. UMC had filed an administrative litigation case against MOEA on December 8, 2006. Taipei High Administrative Court announced and reversed MOEA’s administrative sanction on July 19, 2007. As of the reporting date, the Company is not aware whether MOEA has had an appeal against the Company.

Financial risk management objectives and policies

The Company’s principal financial instruments, other than derivatives, is comprise of cash and cash equivalents, common stock, preferred stock, convertible bonds, open-end funds, bank loans, and bonds payable. The main purpose of these financial instruments is to manage financing for the Company’s operations. The Company also holds various other financial assets and liabilities such as accounts receivable and accounts payable, which arise directly from its operations.

The Company also enters into derivative transactions, including credit-link deposits, interest rate swaps and forward currency contracts. The purpose of these derivative transactions is to mitigate interest rate risk and foreign currency exchange risks arising from the Company’s operations and financing activities.

The main risks arising from the Company’s financial instruments include cash flow interest rate risk, foreign currency risk, commodity price risk, credit risk, and liquidity risk.

Cash flow interest rate risk

The Company utilizes interest rate swap agreements to avoid its cash flow interest rate risk on its counter-floating rate of unsecured domestic bonds issued during the period from May 21 to June 24, 2003. The periods of the interest rate swap agreements are the same as those of the domestic bonds, which are five and seven years. The floating rate is reset annually.

Foreign currency risk

The Company has foreign currency risk arising from purchases or sales. The Company utilizes spot or forward contracts to avoid foreign currency risk. The Company buys or sells the same amount of foreign currency with hedged through forward hedging items for contracts. In principal, the Company does not carry out any forward contracts for uncertain commitments.

Commodity price risk

The Company’s exposure to commodity price risk is minimal.

Credit risk

The Company trades only with established and creditworthy third parties. It is the Company’s policy that all customers who wish to trade on credit terms are subject to credit verification procedures. In addition, receivable balances are monitored on an ongoing basis, which consequently minimizes the Company’s exposure to bad debts.

With respect to credit risk arising from the other financial assets of the Company, which are comprised of cash and cash equivalents, available-for-sale financial assets and certain derivative instruments, the Company’s exposure to credit risk arising from the default of counter-parties is limited to the carrying amount of these instruments.

Although the Company trades only with established third parties, it will request collateral to be provided by third parties with less favorable financial positions.

Liquidity risk

The Company’s objective is to maintain a balance of funding continuity and flexibility through the use of financial instruments such as cash and cash equivalents, bank loans and bonds.

The methods and assumptions used to measure the fair value of financial instruments are as follows:

The book values of short-term financial instruments approximate their fair value due to their short maturities. Short-term financial instruments include cash and cash equivalents, notes receivable, accounts receivable, current portion of capacity deposits, and payables.

ii.

The fair value of financial assets at fair value through profit or loss and available-for-sale financial assets are based on the quoted market prices.

iii.

The fair value of held-to-maturity financial assets and long-term investments accounted for under equity method are based on the quoted market prices. If market prices are unavailable, the Company estimates the fair value based on the book values.

iv.

The fair value of financial assets measured at cost and prepayment for long-term investments are unable to estimate since there is no active market in trading those unlisted investments.

The fair value of deposits-out is based on their book value since the deposit periods are principally within one year and renewed upon maturity.

vi.

The fair value of bonds payable is determined by the market price.

vii.

The fair value of derivative financial instruments is based on the amount the Company expects to receive (positive) or to pay (negative) assuming that the contracts are settled in advance at the balance sheet date.

The fair value of the Company’s financial instruments is determined by the quoted prices in active markets, or if the market for a financial instrument is not active, the Company establishes fair value by using a valuation technique:

Credit risk

The counterparties of the above investments are major international financial institutions. The repayment in full of these investments is subject to the non-occurrence of one or more credit events, which are referenced to the entities’ fulfillment of their own obligations as well as repayment of their corporate bonds. Upon the occurrence of one or more of such credit events, the Company and its subsidiary, UMC JAPAN, may receive less than the full amount of these investments or nothing. The Company and its subsidiary, UMC JAPAN, have selected reference entities with high credit ratings to minimize the credit risk.

Liquidity risk

Early withdrawal is not allowed for the above investments unless called by the issuer. However, the anticipated liquidity risk is low since most of the investments will either have matured within one year, or are relatively liquid in the secondary market.

Market risk

There is no market risk for the above investments except for the fluctuations in the exchange rates of US Dollars and Japanese Yen to NT Dollars at the balance sheet date and the settlement date.

(5)

The Company and its subsidiary, UMC JAPAN, entered into interest rate swap and forward contracts for hedging the interest rate risk arising from the counter-floating rate of domestic bonds and for hedging the exchange rate risk arising from the net assets or liabilities denominated in foreign currency. The hedging strategy was developed with the objective to reduce the market risk for non-trading purpose. The relevant information on the derivative financial instruments entered into by the Company is as follows:

The Company utilized interest rate swap agreements to hedge its interest rate risk on its counter-floating rate of unsecured domestic bonds issued during the period from May 21 to June 24, 2003. The periods of the interest rate swap agreements are the same as those of the domestic bonds, which are five and seven years. The floating rate is reset annually. The details of interest rate swap agreements are summarized as follows:

As of June 30, 2007 and 2006, the Company had the following interest rate swap agreements in effect:


Notional Amount	Contract Period	Interest Rate Received	Interest Rate Paid
NT$7,500 million	May 21, 2003 to June 24, 2008	4.0% minus USD 12-Month LIBOR	1.52	%
NT$7,500 million	May 21, 2003 to June 24, 2010	4.3% minus USD 12-Month LIBOR	1.48	%

The details of forward contracts entered into by the Company and its subsidiary, UMC JAPAN, are summarized as follows:

The Company and its subsidiary, UMC JAPAN, did not hold any forward contracts as of June 30, 2007.

The Company did not hold any forward contracts as of June 30, 2006.

UMC JAPAN


Type	Notional Amount	Contract Period
Forward contracts	Sell USD 3 million	June 14, 2006 to July 31, 2006

Transaction risk

(a)

Credit risk

There is no significant credit risk exposure with respect to the above transactions as the counter-parties are reputable financial institutions with good global standing.

(b)

Liquidity and cash flow risk

The cash flow requirements on the interest rate swap agreements are limited to the net interest payables or receivables arising from the differences in the swap rates. The cash flow requirements on forward contracts are limited to the net difference between the forward and spot rates at the settlement date. Therefore, no significant cash flow risk is anticipated since the working capital is sufficient to meet the cash flow requirements.

(c)

Market risk

Interest rate swap agreements and forward contracts are intended for hedging purposes. Gains or losses arising from the fluctuations in interest rates and exchange rates are likely to be offset against the gains or losses from the hedged items. As a result, no significant exposure to market risk is anticipated.

The presentation of derivative financial instruments on financial statements

English Translation of a Report Originally Issued in Chinese

To United Microelectronics Corporation

We have audited the accompanying consolidated balance sheets of United Microelectronics Corporation and Subsidiaries as of June 30, 2007 and 2006, and the related consolidated statements of income, change in stockholders’ equity and cash flows for the six-month periods ended June 30, 2007 and 2006. The consolidated financial statements are the responsibility of United Microelectronics Corporation’s management. Our responsibility is to express an opinion on these financial statements based on our audits. As described in Note 4(9) to the consolidated financial statements, certain long-term investments were accounted for under the equity method based on the June 30, 2007 and 2006 financial statements of the investees, which were audited by other auditors. Our opinion insofar as it relates to the investment income amounting to NT$463 million and NT$473 million for the six-month periods ended June 30, 2007 and 2006, respectively, and the related long-term investment balances of NT$7,219 million and NT$6,018 million as of June 30, 2007 and 2006, respectively, is based solely on the reports of the other auditors.

We conducted our audits in accordance with auditing standards generally accepted in the Republic of China and “Guidelines for Certified Public Accountants’ Examination and Reports on Financial Statements”, which require that we plan and perform the audit to obtain reasonable assurance about whether the 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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall consolidated financial statement presentation. We believe that our audits and the reports of the other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the reports of other auditors, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of United Microelectronics Corporation and Subsidiaries as of June 30, 2007 and 2006, and the results of their consolidated operations and their consolidated cash flows for the six-month periods ended June 30, 2007 and 2006, in conformity with the “Business Entity Accounting Law”, the “Regulation on Business Entity Accounting Handling”, the “Guidelines Governing the Preparation of Financial Reports by Securities Issuers” and accounting principles generally accepted in the Republic of China.

As described in Note 3 to the consolidated financial statements, effective from January 1, 2006, United Microelectronics Corporation and Subsidiaries have adopted the ROC Statement of Financial Accounting Standards No. 34, “Financial Instruments: Recognition and Measurement” and No. 36, “Financial Instruments: Disclosure and Presentation” to account for the financial instruments.

As described in Note 3 to the consolidated financial statements, effective from January 1, 2006, goodwill is no longer to be amortized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2007 and 2006

(Expressed in Thousands of New Taiwan Dollars unless Otherwise Specified)

1.	HISTORY AND ORGANIZATION

United Microelectronics Corporation (UMC) was incorporated in May 1980 and commenced operations in April 1982. UMC is a full service semiconductor wafer foundry, and provides a variety of services to satisfy customer needs. These services include intellectual property, embedded IC design, design verification, mask tooling, wafer fabrication, and testing. UMC’s common shares were publicly listed on the Taiwan Stock Exchange (TSE) in July 1985 and its American Depositary Shares (ADSs) were listed on the New York Stock Exchange (NYSE) in September 2000.

The numbers of employees as of June 30, 2007 and 2006 were 14,495 and 13,457, respectively.

2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements were prepared in conformity with the “Business Entity Accounting Law”, “Regulation on Business Entity Accounting Handling”, “Guidelines Governing the Preparation of Financial Reports by Securities Issuers” and accounting principles generally accepted in the Republic of China (R.O.C.).

Summary of significant accounting policies is as follows:

General Descriptions of Reporting Entities

(1)

Principles of Consolidation

Investees in which UMC, directly or indirectly, holds more than 50% of voting rights or de facto control with less than 50% of voting rights, are consolidated into UMC’s financial statements. (UMC and the consolidated entities are hereinafter referred to as “the Company”.)

Transactions between consolidated entities are eliminated in the consolidated financial statements. Prior to January 1, 2006, the difference between the acquisition cost and the net equity of a subsidiary as of the acquisition date was amortized over 5 years; however effective January 1, 2006, goodwill arising from new acquisitions is analyzed and accounted for under the ROC Statement of Financial Accounting Standard (SFAS) No. 25, “Business Combination – Accounting Treatment under Purchase Method”, and goodwill is no longer to be amortized.

Foreign Currency Transactions

Transactions denominated in foreign currencies are remeasured into the local functional currencies and recorded based on the exchange rates prevailing at the transaction dates. Monetary assets and liabilities denominated in foreign currencies are remeasured into the local functional currencies at the exchange rates prevailing at the balance sheet date, with the related exchange gains or losses included in the consolidated statements of income. Translation gains or losses from investments in foreign entities are recognized as cumulative translation adjustment in consolidated stockholders’ equity.

Non-monetary assets and liabilities denominated in foreign currencies that are reported at fair value with changes in fair value charged to the consolidated statements of income, are remeasured at the exchange rate at the balance sheet date, with related exchange gains or losses recorded in the consolidated statements of income. Non-monetary assets and liabilities denominated in foreign currencies that are reported at fair value with changes in fair value charged to consolidated stockholders’ equity, are remeasured at the exchange rate at the balance sheet date, with related exchange gains or losses recorded as adjustment items to consolidated stockholders’ equity. Non-monetary assets and liabilities denominated in foreign currencies and reported at cost are remeasured at historical exchange rates.

Use of Estimates

The preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that will affect the amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reported period. Actual results may differ from those estimates.

Translation of Foreign Currency Financial Statements

The financial statements of foreign subsidiaries and the Branch are translated into New Taiwan Dollars using the spot rates as of each financial statement date for asset and liability accounts and average exchange rates for profit and loss accounts. The cumulative translation effects from the subsidiaries and the Branch using functional currencies other than New Taiwan Dollars are included in the cumulative translation adjustment in consolidated stockholders’ equity.

Cash Equivalents

Financial Instruments

In accordance with ROC SFAS No. 34, “Financial Instruments: Recognition and Measurement” and the “Guidelines Governing the Preparation of Financial Reports by Securities Issuers”, financial assets are classified as either financial assets at fair value through profit or loss, held-to-maturity financial assets, financial assets measured at cost, or available-for-sale financial assets. Financial liabilities are recorded at fair value through profit or loss.

Financial instruments at fair value through profit or loss

This category of financial instruments is measured at fair value and changes in fair value are recognized in the consolidated statements of income. Stock of listed companies, convertible bonds, and close-end funds are measured at closing prices as of the balance sheet date. Open-end funds are measured at the unit price of the net assets as of the balance sheet date. The fair value of derivative financial instruments is determined by using valuation techniques commonly used by market participants.

Held-to-maturity financial assets

The Company recognizes an impairment loss if objective evidence of impairment loss exists. However, the impairment loss may be reversed if the value of asset recovers subsequently and the Company concludes that the recovery is related to improvements in events or factors that originally caused the impairment loss. The new cost basis as a result of the reversal cannot exceed the amortized cost prior to the impairment.

Financial assets measured at cost

Available-for-sale financial assets

Available-for-sale financial assets are non-derivative financial instruments not classified as financial assets at fair value through profit or loss, held-to-maturity financial assets, loans and receivables. Subsequent measurement is calculated at fair value. Investments in listed companies are measured at closing prices as of the balance sheet date. Any gain or loss arising from the change in fair value, excluding impairment loss and exchange gain or loss arising from monetary financial assets denominated in foreign currencies, is recognized as an adjustment to consolidated stockholders’ equity until such investment is reclassified or disposed of, upon which the cumulative gain or loss previously charged to consolidated stockholders’ equity will be recorded in the consolidated statement of income.

The Company recognizes an impairment loss when objective evidence of impairment exists. Any reduction in the impairment loss of equity investments in subsequent periods will be recognized as an adjustment to consolidated stockholders’ equity. The impairment loss of a debt security may be reversed and recognized in the current period’s consolidated statement of income if the security recovers and the Company concludes the recovery is clearly related to improvements in the factors or events that originally caused the impairment.

Allowance for Doubtful Accounts

An allowance for doubtful accounts is provided based on management’s judgment of the collectibility and aging analysis of accounts and other receivables.

Inventories

Long-term Investments Accounted for Under the Equity Method

If the recoverable amount of investees accounted for under the equity method is less than its carrying amount, the difference is to be recognized as impairment loss in the current period.

Property, Plant and Equipment


Buildings		8 ~ 55 years

Machinery and equipment		5 years

Transportation equipment		4 ~ 5 years

Furniture and fixtures		2 ~ 14 years

Leased assets and leasehold improvements		The lease period or estimated economic life, whichever is shorter

Intangible Assets

Effective January 1, 2006, goodwill generated from business combinations is no longer subject to amortization.

Technological know-how is stated at cost and amortized over its estimated economic life using the straight-line method.

An impairment loss will be recognized when the decreases in fair value of intangible assets are other than temporary. The book value after recognizing the impairment loss is recorded as the new cost.

Deferred Charges

Convertible and Exchangeable Bonds

The excess of the stated redemption price over par value is accrued as interest payable and expensed over the redemption period using the effective interest method.

When exchangeable bondholders exercise their right to exchange their bonds for reference shares, the book value of the bonds is offset against the book value of the investments in reference shares and the related consolidated stockholders’ equity accounts, with the difference recognized as a gain or loss on disposal of investments.

Pension Plan

All regular employees are entitled to a defined benefit pension plan that is managed by an independently administered pension fund committee. Fund assets are deposited in the committee’s name in the Bank of Taiwan and hence, not associated with UMC. Therefore, fund assets are not to be included in the Company’s consolidated financial statements. Pension benefits for employees of the Branch and overseas subsidiaries are provided in accordance with the local regulations.

The accounting for UMC’s pension liability is computed in accordance with ROC SFAS No.18. Net pension costs of the defined benefit plan are recorded based on an actuarial valuation. Pension cost components such as service cost, interest cost, expected return on plan assets, the amortization of net obligation at transition, pension gain or loss, and prior service cost, are all taken into consideration by the actuary. UMC recognizes expenses from the defined contribution pension plan in the period in which the contribution becomes due.

Employee Stock Option Plan

Treasury Stock

The Company adopted ROC SFAS No. 30, “Accounting for Treasury Stocks” which requires that treasury stock held by the Company to be accounted for under the cost method. The cost of treasury stock is shown as a deduction to consolidated stockholders’ equity, while any gain or loss from selling treasury stock is treated as an adjustment to additional paid-in capital. The Company’s stock held by its subsidiaries is also treated as treasury stock. Cash dividends received by subsidiaries from the Company are recorded as additional paid-in capital—treasury stock transactions.

Revenue Recognition

Allowance for sales returns and discounts are estimated by taking into consideration of customer complaints, historical experiences, management judgment and any other known factors that might significantly affect collectibility. Such allowances are recorded in the same period in which sales are made.

Research and Development Expenditures

Research and development expenditures are charged to expenses as incurred.

Capital Expenditures Versus Operating Expenditures

An expenditure is capitalized when it is probable that the Company will receive future economic benefits associated with the expenditure. Otherwise, the expenditure is expensed as incurred.

Income Tax

Income tax (10%) on unappropriated earnings is recorded as expense in the year in which the shareholders have resolved that the earnings shall be retained.

Earnings per Share

Asset Impairment

Pursuant to ROC SFAS No. 35, the Company assesses indicators of impairment for all its assets (except for goodwill) within the scope of the standard at each balance sheet date. If impairment is indicated, the Company compares the asset’s carrying amount with the recoverable amount of the assets or the cash-generating unit (CGU) associated with the asset and writes down the carrying amount to the recoverable amount where applicable. The recoverable amount is defined as the higher of fair value less the costs to sell and the values in use. For previously recognized losses, the Company assesses at the balance sheet date any indication that the impairment loss no longer exists or may have diminished. If there is any such indication, the Company recalculates the recoverable amount of the asset, and if the recoverable amount has increased as a result of the increase in the estimated service potential of the assets, the Company reverses the impairment loss so that the resulting carrying amount of the asset does not exceed the amount (net of amortization or depreciation) that would otherwise result had no impairment loss been recognized for the assets in prior years.

Impairment losses and reversals are classified as non-operating loss and income, respectively.

3.	ACCOUNTING CHANGES

Goodwill

The Company adopted the amendments to ROC SFAS No. 1, “Conceptual Framework of Financial Accounting and Preparation of Financial Statements,” SFAS No. 5, “Long-Term Investments in Equity Securities,” and SFAS No. 25, “Business Combinations – Accounting Treatment under Purchase Method,” all of which have discontinued the amortization of goodwill effective January 1, 2006. As a result of adopting the revised SFAS No.1, revised SFAS No.5 and revised SFAS No.25 on January 1, 2006, the Company’s total assets as of June 30, 2006 are NT$440 million higher than if it had continued to account for goodwill under the prior year’s requirements. The consolidated net income and earnings per share for the six-month period ended June 30, 2006, are NT$440 million and NT$0.02 higher, respectively, than if the Company had continued to account for goodwill under the prior year’s requirements.

Financial Instruments

The above changes in accounting principles increased the Company’s total assets, total liabilities, and stockholders’ equity as of January 1, 2006 by NT$24,246 million, NT$1,326 million, and NT$22,920 million, respectively; and resulted in an unfavorable cumulative effect of changes in accounting principles of NT$1,189 million deducted from consolidated net income, thereby reducing earnings per share by NT$0.06 for the six-month period ended June 30, 2006.

Payment of all taxes and dues;

Offset prior years’ operation losses;

Set aside 10% of the remaining amount after deducting items (a) and (b) as a legal reserve;

Set aside 0.1% of the remaining amount after deducting items (a), (b), and (c) as directors’ and supervisors’ remuneration; and

After deducting items (a), (b), and (c) above from the current year’s earnings, no less than 5% of the remaining amount together with the prior years’ unappropriated earnings is to be allocated as employees’ bonus, which will be settled through issuance of new shares of UMC, or cash. Employees of UMC’s subsidiaries, meeting certain requirements determined by the board of directors, are also eligible for the employees’ bonus.

The distribution of the remaining portion, if any, will be recommended by the board of directors and subject to the shareholders’ approval.

The policy for dividend distribution should reflect factors such as the current and future investment environment, fund requirements, domestic and international competition and capital budgets; as well as the benefit of shareholders, share bonus equilibrium, and long-term financial planning. The board of directors shall make the distribution proposal annually and present it at the shareholders’ meeting. UMC’s Articles of Incorporation further provide that no more than 80% of the dividends to shareholders, if any, may be paid in the form of stock dividends. Accordingly, at least 20% of the dividends must be paid in the form of cash.

According to the explanatory letter No. 101801 of the Securities and Futures Commission (SFC), if UMC recognizes the investees’ additional paid-in capital - excess from the merger in proportion to the ownership percentage, then the special reserve is exempted for the amount originated from the acquisition of the long-term investments.

If UMC and its investees transfer a portion of the additional paid-in capital to increase capital, a special reserve equal to the amount of the transfer shall be provided according to the explanatory letter No. 101801-1 of the SFC.

In accordance with the explanatory letter No. 170010 of the SFC applicable to listed companies, in the case where the market value of UMC’s stock held by its subsidiaries at period-end is lower than the book value, a special reserve shall be provided in UMC’s accounts in proportion to its ownership percentage.

On February 15, 2005, the Hsinchu District Prosecutor’s Office conducted a search of UMC’s facilities. On February 18, 2005, UMC’s former Chairman Mr. Robert H.C. Tsao, released a public statement, explaining that its assistance to Hejian Technology Corp. (Hejian) did not involve any investment or technology transfer. Furthermore, from the very beginning there was a verbal indication that, at the proper time, UMC would be compensated appropriately for its assistance, and circumstances permitting, at some time in the future, it will push through the merger between two companies. However, no promise was made by UMC and no written agreement was made and executed. Upon UMC’s request to materialize the said verbal indication by compensating in the form of either cash or equity, the Chairman of the holding company of Hejian offered 15% of the approximately 700 million outstanding shares of the holding company of Hejian in return for UMC’s past assistance and for continued assistance in the future.

Immediately after UMC had received such offer, it filed an application with the Investment Commission of the Ministry of Economic Affairs on March 18, 2005 (Ref. No. 94-Lian-Tung-Tzu-0222), for their executive guidance for the successful transfer of said shares to UMC. The shareholders meeting dated June 13, 2005 resolved that to the extent permitted by law UMC shall try to get the 15% of the outstanding shares offered by the holding company of Hejian as an asset of UMC.

The holding company of Hejian offered 106 million shares of its outstanding common shares in return for UMC’s assistance. The holding company of Hejian has put all such shares in escrow. UMC was informed of such escrow on August 4, 2006. The subscription price per share of the holding company of Hejian in the last offering was US$1.1. Therefore, the total market value of the said shares is worth more than US$110 million. However, UMC may not acquire the ownership of nor exercise the rights of the said shares with any potential stock dividend or cash dividend distributed in the future until the ROC laws and regulations allow UMC to acquire and exercise. In the event that any stock dividend or cash dividend is distributed, UMC’s stake in the holding company of Hejian will accumulate accordingly.

In April 2005, UMC’s former Chairman Mr. Robert H.C. Tsao was personally fined with in the aggregate amount of NT$3 million by the Financial Supervisory Commission, Executive Yuan, R.O.C. (ROC FSC) for failure to disclose material information relating to Hejian in accordance with applicable rules. As a result of the imposition of the fines by the ROC FSC, UMC was also fined in the amount of NT$30,000 by Taiwan Stock Exchange (TSE) for the alleged non-compliance with the disclosure rules in relation to the material information. UMC and its former Chairman Mr. Robert H.C. Tsao have filed for administrative appeal and reconsideration with the Executive Yuan, R.O.C. and TSE, respectively. Mr. Robert H.C. Tsao’s administrative appeal was dismissed by the Execution Yuan, R.O.C. on February 21, 2006 and the ROC FSC transferred the case against Mr. Robert H.C. Tsao to the Administrative Enforcement Agency for enforcement of the fine. Mr. Robert H.C. Tsao has filed an administrative action against the ROC FSC with Taipei High Administrative Court on April 14, 2006. As of June 30, 2007, the result of such reconsideration and administrative action has not been finalized. The case is being processed in Taipei High Administrative Court.

For UMC’s assistance to Hejian Technology Corp., UMC’s former Chairman Mr. Robert H.C. Tsao, former Vice Chairman Mr. John Hsuan, and Mr. Duen-Chian Cheng, the General Manager of Fortune Venture Capital Corp., which is 99.99% owned by UMC, were indicted for violating the Business Entity Accounting Law and breach of trust under the Criminal Law by Hsinchu District Court’s Prosecutor’s Office on January 9, 2006. Mr. Robert H.C. Tsao and Mr. John Hsuan had officially resigned from their positions of UMC’s Chairman, Vice Chairman and directors prior to the announcement of the prosecution; for this reason, at the time of the prosecution, Mr. Robert H.C. Tsao and Mr. John Hsuan no longer served as UMC’s directors and had not executed their duties as UMC’s Chairman and Vice Chairman. In the future, if a guilty judgment is pronounced by the court, such consequences would be Mr. Robert H.C. Tsao, Mr. John Hsuan and Mr. Duen-Chian Cheng’s personal concerns only; UMC would not be subject to indictment regarding this case.

On February 15, 2006, UMC was fined in the amount of NT$5 million for unauthorized investment activities in Mainland China, implicating violation of Article 35 of the Act “Governing Relations Between Peoples of the Taiwan Area and the Mainland Area” by the R.O.C. Ministry of Economic Affairs (MOEA). However, as UMC believes it was illegally and improperly fined, UMC had filed an administrative appeal against MOEA to the Executive Yuan on March 16, 2006. On October 19, 2006, Executive Yuan denied the administrative appeal filed by UMC. UMC had filed an administrative litigation case against MOEA on December 8, 2006. Taipei High Administrative Court had announced and reversed MOEA’s administrative sanction on July 19, 2007. As of the reporting date, UMC is not aware whether MOEA has had an appeal against UMC.

Financial risk management objectives and policies

UMC’s principal financial instruments, other than derivatives, is comprise of cash and cash equivalents, common stock, preferred stock, convertible bonds, open-end funds, bank loans, and bonds payable. The main purpose of these financial instruments is to manage financing for UMC’s operations. UMC also holds various other financial assets and liabilities such as accounts receivable and accounts payable, which arise directly from its operations.

UMC also enters into derivative transactions, including credit-link deposits, interest rate swaps and forward currency contracts. The purpose of these derivative transactions is to mitigate interest rate risk and foreign currency exchange risks arising from UMC’s operations and financing activities.

The main risks arising from UMC’s financial instruments include cash flow interest rate risk, foreign currency risk, commodity price risk, credit risk, and liquidity risk.

Cash flow interest rate risk

UMC utilizes interest rate swap agreements to avoid its cash flow interest rate risk on its counter-floating rate of unsecured domestic bonds issued during the period from May 21 to June 24, 2003. The periods of the interest rate swap agreements are the same as those of the domestic bonds, which are five and seven years. The floating rate is reset annually.

Foreign currency risk

UMC has foreign currency risk arising from purchases or sales. UMC utilizes spot or forward contracts to avoid foreign currency risk. UMC buys or sells the same amount of foreign currency with hedged through forward hedging items for contracts. In principal, UMC does not carry out any forward contracts for uncertain commitments.

Commodity price risk

UMC’s exposure to commodity price risk is minimal.

Credit risk

UMC trades only with established and creditworthy third parties. It is UMC’s policy that all customers who wish to trade on credit terms are subject to credit verification procedures. In addition, receivable balances are monitored on an ongoing basis, which consequently minimizes UMC’s exposure to bad debts.

With respect to credit risk arising from the other financial assets of UMC, which are comprised of cash and cash equivalents, available-for-sale financial assets and certain derivative instruments, UMC’s exposure to credit risk arising from the default of counter-parties is limited to the carrying amount of these instruments.

Although UMC trades only with established third parties, it will request collateral to be provided by third parties with less favorable financial positions.

Liquidity risk

UMC’s objective is to maintain a balance of funding continuity and flexibility through the use of financial instruments such as cash and cash equivalents, bank loans and bonds.

The methods and assumptions used to measure the fair value of financial instruments are as follows:

The book value of short-term financial instruments approximates to fair value due to their short maturities. Short-term financial instruments include cash and cash equivalents, notes receivable, accounts receivable, current portion of capacity deposits, and payables.

ii.

The fair value of financial assets at fair value through profit or loss and available-for-sale financial assets are based on the quoted market price.

iii.

The fair value of held-to-maturity financial assets and long-term investments accounted for under equity method are based on the quoted market prices. If market prices are unavailable, UMC estimates the fair value based on the book values.

iv.

The fair value of financial assets measured at cost and prepayment for long-term investment are unable to estimate since there is no active market in trading those unlisted investments.

The fair value of deposits-out is based on their book value since the deposit periods are principally within one year and renewed upon maturity.

vi.

The fair value of bonds payable is determined by the market values.

vii.

The fair value of derivative financial instruments is based on the amount UMC expects to receive (positive) or to pay (negative) assuming that the contracts are settled in advance at the balance sheet date.

The fair value of UMC’s financial instruments is determined by the quoted prices in active markets, or if the market for a financial instrument is not active, UMC establishes fair value by using a valuation technique:
