Review Report of Independent Auditors

To United Microelectronics Corporation

Introduction

We have reviewed the accompanying consolidated balance sheets of United Microelectronics Corporation and its subsidiaries (collectively, the "Company") as of March 31, 2022 and 2021, the related consolidated statements of comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2022 and 2021, and notes to the consolidated financial statements, including the summary of significant accounting policies (together "the consolidated financial statements"). Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Accounting Standard 34,"Interim Financial Reporting" as endorsed and became effective by Financial Supervisory Commission of the Republic of China. Our responsibility is to express a conclusion on these consolidated financial statements based on our reviews.

Scope of Review

We conducted our reviews in accordance with Statement of Auditing Standards No. 65, "Review of Financial Information Performed by the Independent Auditor of the Entity" of the Republic of China. A review of consolidated financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in the Republic of China and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our reviews and the review reports of other independent auditors (please refer to the Other Matter paragraph of our report), nothing has come to our attention that causes us to believe that the accompanying consolidated financial statements do not present fairly, in all material respects, the consolidated financial position of the Company as of March 31, 2022 and 2021, and its consolidated financial performance and cash flows for the three-month periods ended March 31, 2022 and 2021, in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Accounting Standard 34,"Interim Financial Reporting" as endorsed and became effective by Financial Supervisory Commission of the Republic of China.

Other Matter - Making Reference to the Reviews of Other Independent Auditors

We did not review the financial statement of certain associates and joint ventures accounted for under the equity method. Our review, insofar as it related to the investments accounted for under the equity method balances of NT$27,255 million and NT$31,316 million, which represented 5.64% and 7.94% of the total consolidated assets as of March 31, 2022 and 2021, respectively, the related shares of profit or loss from the associates and joint ventures in the amount of NT$(1,958) million and NT$1,711 million, which represented (8.28)% and 15.58% of the consolidated income from continuing operations before income tax for the three-month periods ended March 31, 2022 and 2021, respectively, and the related shares of other comprehensive income from the associates and joint ventures in the amount of NT$96 million and NT$852 million, which represented 0.45% and 6.34% of the consolidated total comprehensive income for the three-month periods ended March 31, 2022 and 2021, respectively, are based solely on the reports of other independent auditors.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

For the Three-Month Periods Ended March 31, 2022 and 2021

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

1.	HISTORY AND ORGANIZATION

United Microelectronics Corporation (UMC) was incorporated in Republic of China (R.O.C.) 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. UMC's ordinary shares were publicly listed on the Taiwan Stock Exchange (TWSE) in July 1985 and its American Depositary Shares (ADSs) were listed on the New York Stock Exchange (NYSE) in September 2000.

The address of its registered office and principal place of business is No. 3, Li-Hsin Road II, Hsinchu Science Park, Hsinchu City, Taiwan. The principal operating activities of UMC and its subsidiaries (collectively as "the Company") are described in Notes 4(3) and 14.

2.	DATE AND PROCEDURES OF AUTHORIZATION OF FINANCIAL STATEMENTS FOR ISSUE

The consolidated financial statements of the Company were authorized for issue in accordance with a resolution of the Board of Directors' meeting on April 27, 2022.

3.	NEWLY ISSUED OR REVISED STANDARDS AND INTERPRETATIONS

(1)

The Company applied International Financial Reporting Standards, International Accounting Standards, and Interpretations issued, revised or amended which are endorsed by Financial Supervisory Commission ("FSC") and become effective for annual periods beginning on or after January 1, 2022. Apart from the impact of the standards and interpretations which is described below, all other standards and interpretations have no material impact on the Company's financial position and performance.

Onerous Contracts - Cost of Fulfilling a Contract (Amendments to IAS 37)
The amendments clarify what costs a company should include as the cost of fulfilling a contract when assessing whether a contract is onerous, which specifying that the cost of fulfilling a contract comprises the costs that relate directly to the contract. The amendments are effective for contracts for which the Company has not yet fulfilled all its obligations on or after January 1, 2022 (the date of initial application). In accordance with the transitional provisions of IAS 37, the Company did not restate the comparative information and recognized the cumulative effect of initially applying the amendments, which resulting in an increase in the provisions (classified under other current liabilities) of NT$220 million, a decrease in retained earnings of NT$154 million and a decrease in non-controlling interest of NT$66 million, respectively as of January 1, 2022.

(2)	Standards issued by International Accounting Standards Board ("IASB") but not yet endorsed by FSC (the effective dates are to be determined by FSC) are listed below:

New, Revised or Amended Standards and Interpretations		Effective Date issued by IASB
IFRS 10 "Consolidated Financial Statements" and IAS 28 "Investments in Associates and Joint Ventures" - Sale or Contribution of Assets between an Investor and its Associate or Joint Ventures		To be determined by IASB
IFRS 17 "Insurance Contracts"		January 1, 2023
Amendments to IAS 1 "Presentation of Financial Statements" - Classification of Liabilities as Current or Non-current		January 1, 2023
Amendments to IAS 1 "Presentation of Financial Statements" - Disclosure Initiative - Accounting Policies		January 1, 2023
Amendments to IAS 8 "Accounting Policies, Changes in Accounting Estimates and Errors" - Definition of Accounting Estimates		January 1, 2023
Amendment to IAS 12 "Income Taxes" -Deferred Tax related to Assets and Liabilities arising from a Single Transaction		January 1, 2023

The potential effects of adopting the standards or interpretations issued by IASB but not yet endorsed by FSC on the Company's financial statements in future periods are summarized as below:

b.	IFRS 10 "Consolidated Financial Statements" ("IFRS 10") and IAS 28 "Investments in Associates and Joint Ventures" - Sale or Contribution of Assets between an Investor and its Associate or Joint Ventures (Amendment) ("IAS 28")

The amendments address the inconsistency between the requirements in IFRS 10 and IAS 28, in dealing with the loss of control of a subsidiary that is contributed to an associate or a joint venture. IAS 28 restricts gains and losses arising from contributions of non-monetary assets to an associate or a joint venture to the extent of the interest attributable to the other equity holders in the associate or joint venture. IFRS 10 requires full profit or loss recognition on the loss of control of a subsidiary. IAS 28 was amended so that the gain or loss resulting from the sale or contribution of assets that constitute a business as defined in IFRS 3 "Business Combinations" ("IFRS 3") between an investor and its associate or joint venture is recognized in full.

IFRS 10 was also amended so that the gain or loss resulting from the sale or contribution of a subsidiary that does not constitute a business as defined in IFRS 3 between an investor and its associate or joint venture is recognized only to the extent of the unrelated investors' interests in the associate or joint venture.

c.	IFRS 17 "Insurance Contracts" ("IFRS 17")

IFRS 17 provides a comprehensive model for insurance contracts, covering all relevant accounting aspects (including recognition, measurement, presentation and disclosure requirements). The core of IFRS 17 is the General (building block) Model, under this model, on initial recognition, an entity shall measure a group of insurance contracts at the total of the fulfilment cash flows and the contractual service margin. The carrying amount of a group of insurance contracts at the end of each reporting period shall be the sum of the liability for remaining coverage and the liability for incurred claims.

Other than the General Model, the standard also provides a specific adaptation for contracts with direct participation features (the Variable Fee Approach) and a simplified approach (Premium Allocation Approach) mainly for short-duration contracts.

IFRS 17 was issued in May 2017 and it was amended in 2020 and 2021. The amendments include deferral of the date of initial application of IFRS 17 by two years to annual beginning on or after 1 January 2023 (from the original effective date of 1 January 2021); provide additional transition reliefs; simplify some requirements to reduce the costs of applying IFRS 17 and revise some requirements to make the results easier to explain. IFRS 17 replaces an interim Standard - IFRS 4 Insurance Contracts - from annual reporting periods beginning on or after 1 January 2023.

d.	IAS 1 "Presentation of Financial Statements" ("IAS 1") - Classification of Liabilities as Current or Non-current (Amendment)

These are the amendments to paragraphs 69-76 of IAS 1 presentation of financial statements and the amended paragraphs related to the classification of liabilities as current or non-current.

e.	IAS 1 "Presentation of Financial Statements" ("IAS 1") - Disclosure Initiative - Accounting Policies (Amendment)

The amendments improve accounting policy disclosures that to provide more useful information to investors and other primary users of the financial statements.

f.	IAS 8 "Accounting Policies, Changes in Accounting Estimates and Errors" ("IAS 8") - Definition of Accounting Estimates (Amendment)

The amendments introduce the definition of accounting estimates and included other amendments to IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors to help companies distinguish changes in accounting estimates from changes in accounting policies.

g.	IAS 12 "Income Taxes" ("IAS 12") - Deferred Tax related to Assets and Liabilities arising from a Single Transaction (Amendment)

The amendments narrow the scope of the recognition exemption in paragraphs 15 and 24 of IAS 12 so that it no longer applies to transactions that, on initial recognition, give rise to equal taxable and deductible temporary differences.

The Company is currently evaluating the potential impact of the aforementioned standards and interpretations listed (b) - (g) to the Company's financial position and performance, and the related impact will be disclosed when the evaluation is completed.

Note A: Beginning from June 2015, the Company accounts for its investment in FARADAY as an associate given the fact that the Company obtained the ability to exercise significant influence over FARADAY through representation on its Board of Directors.

Note B: Beginning from June 2020, the Company accounts for its investment in UNIMICRON as an associate given the fact that the Company obtained the ability to exercise significant influence over UNIMICRON through representation on its Board of Directors.

Note C: When the Company's share of losses of an associate equals or exceeds its interest in that associate, the Company discontinues recognizing its share of further losses. Additional losses and liabilities are recognized only to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of that associate.

Note D: The Company follows international accounting practices in equity accounting for limited partnerships and uses the equity method to account for these investees.

The carrying amount of investments accounted for using the equity method for which there are published price quotations amounted to NT$13,027 million, NT$12,198 million and NT$10,958 million, as of March 31, 2022, December 31, 2021 and March 31, 2021, respectively. The fair value of these investments were NT$59,298 million, NT$53,491 million and NT$19,730 million as of March 31, 2022, December 31, 2021 and March 31, 2021, respectively.

Certain investments accounted for under the equity method were audited by other independent accountants. Shares of profit or loss of these associates and joint ventures amounted to NT$(1,958) million and NT$1,711 million for the three-month periods ended March 31, 2022 and 2021, respectively. Share of other comprehensive income (loss) of these associates and joint ventures amounted to NT$96 million and NT$852 million for the three-month periods ended March 31, 2022 and 2021, respectively. The balances of investments accounted for under the equity method were NT$27,255 million, NT$39,806 million and NT$31,316 million as of March 31, 2022, December 31, 2021 and March 31, 2021, respectively.

Although the Company is the largest shareholder of some associates; after comprehensive assessment, the Company does not own the major voting rights as the remaining voting rights holders are able to align and prevent the Company from ruling the relevant operation. Therefore, the Company does not control but owns significant influence over the aforementioned associates.

None of the aforementioned associates were pledged.

b.	Financial information of associates:

There is no individually significant associate for the Company. When an associate is a foreign operation, and the functional currency of the foreign entity is different from the Company, an exchange difference arising from translation of the foreign entity will be recognized in other comprehensive income (loss). Such exchange differences recognized in other comprehensive income (loss) in the financial statements for the three-month periods ended March 31, 2022 and 2021 were NT$38 million and NT$1 million, respectively, which were not included in the following table.

The aggregate amount of the Company's share of all its individually immaterial associates that are accounted for using the equity method were as follows:

	For the three-month periods ended March 31,
	2022	2021

In accordance with IFRS 9, the value of the exchange right, call option and put option (together referred to as Option) of the exchangeable bonds was separated from the host and accounted for as "financial liabilities at fair value through profit or loss, current". The effective rate of the host bond was 3.49%. The terms and conditions of the bonds are as follows:

i.	Issue Amount: US$400 million

ii.	Period: July 7, 2021 - July 7, 2026 (Maturity Date)

iii.	Redemption:

(i)

UMC may, at its option, redeem in whole or in part at the principal amount of the bonds with an interest calculated at the rate of -0.625% per annum (the Early Redemption Amount) at any time after the third anniversary from the issue date and prior to the Maturity Date, if the closing price of the common shares of Novatek Microelectronics Corporation ("Novatek") on the Taiwan Stock Exchange (the "TWSE"), converted into U.S. dollars at the prevailing exchange rate, for 20 out of 30 consecutive trading days prior to the publication of the redemption notice is at least 130% of the quotient of the Early Redemption Amount multiplied by the then exchange price (converted into U.S. dollars at the Fixed Exchange Rate), divided by the principal amount of the bonds. The Early Redemption Amount will be converted into NTD based on the Fixed Exchange Rate (NTD 27.902=USD 1.00), and this fixed NTD amount will then be converted using the prevailing exchange at the time of redemption for payment in USD.

(ii)	UMC may redeem the outstanding bonds in whole, but not in part, at the Early Redemption Amount, in the event that over 90% of the bonds have been previously redeemed, repurchased and cancelled or exchanged.

(iii)

In the event of any change in ROC taxation resulting in increase of tax obligation or the necessity to pay additional interest expense or increase of additional costs to UMC, UMC may redeem the outstanding bonds in whole, but not in part, at the Early Redemption Amount. Bondholders may elect not to have their bonds redeemed but with no entitlement to any additional amounts or reimbursement of additional taxes.

(iv)	All or any portion of the bonds will be redeemable at put price at the option of bondholders on July 7, 2024 at 98.14% of the principal amount.

(v)

In the event that the common shares of Novatek cease to be listed or are suspended from trading for a period equal to or exceeding 30 consecutive trading days on the TWSE, each bondholder shall have the right to require UMC to redeem the bonds, in whole but not in part, at the Early Redemption Amount.

(vi)	Upon the occurrence of a change of control (as defined in the indenture) of UMC, each bondholder shall have the right to require UMC to redeem the bonds, in whole but not in part, at the Early Redemption Amount.

iv.	Terms of Exchange:

(i)	Underlying Securities: Common Shares of Novatek

(ii)

Exchange Period: The bonds are exchangeable at any time on or after October 8, 2021 and prior to June 27, 2026, into Novatek common shares. If for any reason UMC does not have sufficient Novatek common shares to deliver upon the exchange of any bond, then, UMC will pay to the exchanging bondholder an amount in U.S. dollars equal to the product of the volume-weighted average closing price per Novatek common share on the TWSE for five consecutive trading days starting from and including the applicable exercise date (as defined in the indenture) (or such fewer number of trading days as are available within ten days starting from and including the applicable exercise date) each converted into USD at the prevailing rate on the day preceding the applicable trading day and the number of Novatek common shares that UMC is unable to deliver. Provided, however, that if the exercise date falls within 5 business days from the beginning of, and during, any closed period, the right of the converting holder of the bonds to vote with respect to the shares it receives will be subject to certain restrictions.

(iii)

Exchange Price and Adjustment: The exchange price was originally NT$731.25 per Novatek common share. The exchange price will be subject to adjustments upon the occurrence of certain events set out in the indenture. The exchange price was NT$709.2 per Novatek common share on March 31, 2022.

v.	Redemption on the Maturity Date:

The bonds will be redeemed with 96.92% principal amount on the maturity date unless:

(ii)	The bondholders shall have exercised the exchange right before maturity; or

(iii)

The bonds shall have been redeemed or repurchased by UMC and cancelled.

(15)	Post-Employment Benefits

a.	Defined contribution plan

The employee pension plan under the Labor Pension Act of the R.O.C. is a defined contribution plan. Pursuant to the plan, UMC and its domestic subsidiaries make monthly contributions of 6% based on each individual employee's salary or wage to employees' pension accounts. Pension benefits for employees of the Singapore branch and subsidiaries overseas are provided in accordance with the local regulations. Total pension expenses of NT$456 million and NT$401 million were contributed by the Company for the three-month periods ended March 31, 2022 and 2021, respectively.

b.	Defined benefit plan

The employee pension plan mandated by the Labor Standards Act of the R.O.C. is a defined benefit plan. The pension benefits are disbursed based on the units of service years and average monthly salary prior to retirement according to the Labor Standards Act. Two units per year are awarded for the first 15 years of services while one unit per year is awarded after the completion of the 15th year and the total units will not exceed 45 units. The Company contributes an amount equivalent to 2% of the employees' total salaries and wages on a monthly basis to the pension fund deposited with the Bank of Taiwan under the name of a pension fund supervisory committee. The pension fund is managed by the government's designated authorities and therefore is not included in the Company's consolidated financial statements. Pension cost for an interim period is calculated on a year-to-date basis by using the actuarially determined pension cost rate at the end of the prior financial year. For the three-month periods ended March 31, 2022 and 2021, total pension expenses of NT$8 million and NT$6 million, respectively, were recognized by the Company.

c.	Retained earnings and dividend policies:

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

i.	Payment of taxes.

ii.	Making up loss for preceding years.

iii.	Setting aside 10% for legal reserve, except for when accumulated legal reserve has reached UMC's paid-in capital.

iv.	Appropriating or reversing special reserve by government officials or other regulations.

The remaining, if applicable, may be distributed preferentially as preferred shares dividends for the current year, and if there is still a remaining balance, in addition to the previous year's unappropriated earnings, UMC shall distribute it according to the distribution plan proposed by the Board of Directors according to the dividend policy and submitted to the shareholders' meeting for approval.

Because UMC conducts business in a capital intensive industry and continues to operate in its growth phase, the dividend policy of UMC shall be determined pursuant to factors such as the investment environment, its funding requirements, domestic and overseas competitive landscape and its capital expenditure forecast, as well as shareholders' interest, balancing dividends and UMC's long-term financial planning. The Board of Directors shall propose the distribution plan and submit it to the shareholders' meeting every year. The distribution of shareholders' dividend shall be allocated as cash dividend in the range of 20% to 100%, and stock dividend in the range of 0% to 80%.

According to the regulations of Taiwan FSC, UMC is required to appropriate a special reserve in the amount equal to the sum of debit elements under equity, such as unrealized loss on financial instruments and debit balance of exchange differences on translation of foreign operations, at every year-end. Such special reserve is prohibited from distribution. However, if any of the debit elements is reversed, the special reserve in the amount equal to the reversal may be released for earnings distribution or offsetting accumulated deficits.

The appropriation of earnings for 2020 was approved by the shareholders' meeting held on July 7, 2021, while the appropriation of earnings for 2021 was proposed by the Board of Directors' meeting on February 24, 2022. The details of distribution were as follows:

In addition, the Board of Directors' meeting held on February 24, 2022 proposed to distribute cash from additional paid-in capital of NT$37,446 million, at approximately NT$3.00 per share.

The aforementioned 2020 appropriation approved by shareholders' meeting was consistent with the resolutions of the Board of Directors' meeting held on February 24, 2021.

The cash dividend per share for 2020 was adjusted to NT$1.59988820 per share. The adjustment was due to the net increase of outstanding common shares from cancellation and issuance of the restricted stocks.

The appropriation of 2021 unappropriated retained earnings has not yet been approved by the shareholders' meeting as of the reporting date.

(19)	Share-Based Payment

a.	Treasury stock plan for employees

In September 2020, the Company executed a compensation plan to offer 105 million shares of treasury stock to qualified employees of the Company. The compensation cost for the share-based payment was measured at fair value, having recognized in expense the difference between the closing quoted market price of the shares at the grant date and the cash received from employees. The closing quoted market price of the Company's shares on the grant date was NT$21.45 per share. For the stocks vested on the date of grant, the Company recognized the entire compensation cost once granted, whereas for the stocks with requisite service conditions to vest at the end of one year from the date of grant, the Company recognizes the compensation cost over the period in which the services conditions are fulfilled, together with a corresponding increase in equity. The compensation plan had expired in September 2021. For the three-month period ended March 31, 2021, the compensation cost of NT$73 million was recognized in expenses by the Company.

b.	Restricted stock plan for employees

On June 10, 2020, the shareholders approved a compensation plan in their meeting to issue restricted stocks to qualified employees of UMC without consideration. The maximum shares to be issued are 233 million common shares. The Company is authorized to issue restricted stocks in one tranche or in installments, under the custody of trust institution, within one year from the date of receiving the effective registration from the competent authority.

The issuance plan was authorized for effective registration by the Securities and Futures Bureau of the FSC and accordingly, 1 million shares and 200 million shares of restricted stock for employees were issued without consideration on June 9, 2021 and September 1, 2020, respectively. The life of the plan is four years. Beginning from the end of two years since the date of grant, those employees who fulfill both service period and performance conditions set by the Company are gradually eligible to the vested restricted stocks at certain percentage and time frame. For those employees who fail to fulfill the vesting conditions, the Company will recall and cancel their stocks without consideration. During the vesting period, the restricted stock holders are entitled the same rights as those of common stock holders including the right to receive dividends, but are restricted to sell, pledge, set guarantee, transfer, grant, or dispose the restricted stocks in any other ways. Related information can be obtained from the "Market Observation Post System" on the website of the TWSE.

The aforementioned compensation costs for the equity-settled share-based payment were measured at fair value based on the closing quoted market price of the shares on the grant date, NT$53.0 and NT$21.8 per share, respectively. The unvested restricted stocks issued on the grant date for employees are recognized in unearned employee compensation as a transitional contra equity account and such account shall be amortized as compensation expense over the vesting period. For the three-month periods ended March 31, 2022 and 2021, the compensation costs of NT$377 million and NT$371 million, respectively, were recognized in expenses by the Company.

In June 2021 and September 2020, the Company executed a compensation plan to grant 1 million units and 26 million units of cash-settled stock appreciation right to qualified employees of the Company without consideration, respectively. One unit of stock appreciation right to employees represents a right to the intrinsic value of one common share of UMC. The life of the plan is four years. Beginning from the end of two years since the date of grant, those employees who fulfill both service period and performance conditions set by the Company are gradually eligible to the vested stock appreciation right at certain percentage and time frame. For those employees who fail to fulfill the vesting conditions, the Company will withdraw their rights without consideration. During the vesting period, the holders of the stock appreciation right are not entitled the same rights as those of common stock holders of UMC.

The compensation cost for the cash-settled share-based payment was measured at fair value on the grant date by using Black-Scholes Option Pricing Model and will be remeasured at the end of each reporting period until settlement. As of March 31, 2022, the assumptions used are as follows:

	Granted in June 2021	Granted in September 2020
Share price of measurement date (NT$/ per share)	$54.00	$54.00
Expected volatility	39.07%-43.54%	31.03%-44.31%
Expected life	1.19-3.19 years	0.42-2.42 years
Expected dividend yield	5.27%	5.27%
Risk-free interest rate	0.65%-0.84%	0.53%-0.80%

For the three-month periods ended March 31, 2022 and 2021, the compensation costs of NT$55 million and NT$62 million, respectively, were recognized in expenses by the Company. The liabilities for stock appreciation right recognized which were classified under other payables and other noncurrent liabilities-others amounted to NT$420 million, NT$352 million and NT$143 million as of March 31, 2022, December 31, 2021 and March 31, 2021, respectively.

The Board of Directors of UMC resolved in October 2014 to participate in a 3-way agreement with Xiamen Municipal People's Government and FUJIAN ELECTRONIC & INFORMATION GROUP to form a company which will focus on 12'' wafer foundry services. The Company obtained R.O.C. government authority's approval for the investment and invested RMB 8.3 billion in USCXM in instalments from January 2015 to September 2018, according to the agreement that the Company obtained the ability to exercise control. Furthermore, based on the agreement, UMC recognized a financial liability in other financial liabilities, current and other noncurrent liabilities-others, respectively for the purchase from the other investors of their investments in USCXM at their original investment cost plus interest totally amounting to RMB 4.9 billion, beginning from the seventh year (2022) following the last instalment payment made by the other investors. Accordingly, the Company recognizes non-controlling interests as required by IFRS 10 during the reporting period. At the end of each reporting period, the Company recognizes a financial liability for its commitment to the other investors in accordance with IFRS 9, at the same time derecognizing the non-controlling interests. Any difference between the financial liability and the non-controlling interests balance is recognized in equity.

On August 31, 2017, the Taichung District Prosecutors Office indicted UMC based on the Trade Secret Act of R.O.C., alleging that employees of UMC misappropriated the trade secrets of MICRON TECHNOLOGY, INC. ("MICRON"). On June 12, 2020, an adverse ruling issued by the District Court of Taichung in a suit alleged that UMC, two of its current employees and a former employee engaged in the misappropriation of trade secrets. UMC appealed against the sentence. On November 26, 2021, UMC and MICRON announced a settlement agreement between the two companies for all legal proceedings worldwide (the "Settlement Agreement"). Accordingly, MICRON submitted a motion to withdraw the case. On January 27, 2022, the Intellectual Property and Commercial Court announced its ruling of this case and UMC was sentenced to a fine of NT$20 million, subject to a two-year term of probation.

On December 5, 2017, MICRON filed a civil action with similar cause against UMC with the United States District Court, Northern District of California. MICRON claimed entitlement to the actual damages, treble damages and relevant fees and requested the court to issue an order that enjoins UMC from using its trade secrets in question. In accordance with the Settlement Agreement, the court issued a dismissal of the case with prejudice in January 2022.

On January 12, 2018, UMC filed three patent infringement actions with the Fuzhou Intermediate People's Court against, among others, MICRON (XI'AN) CO., LTD. and MICRON (SHANGHAI) TRADING CO., LTD., requesting the court to order the defendants to stop manufacturing, processing, importing, selling, and committing to sell the products deploying the infringing patents in question, and also to destroy all inventories and related molds and tools. On July 3, 2018, the Fuzhou Intermediate People's Court granted preliminary injunction against the aforementioned two defendants, holding that the two defendants must immediately cease to manufacture, sell, and import products that infringe the patent rights of UMC. The court approved withdrawal of one of the patent infringement actions on our motion while the other two actions are still on trial. In accordance with the Settlement Agreement, UMC submitted a motion to withdraw the case, and the motion is currently pending.

The amounts of aforementioned fine from ruling of the Intellectual Property and Commercial Court and the worldwide settlement between UMC and MICRON were recorded in non-operating other losses and have no material financial and operational effect on UMC's business for the years presented.

(2)	Financial risk management objectives and policies

The Company's risk management objectives are to manage the market risk, credit risk and liquidity risk related to its operating activities. The Company identifies, measures and manages the aforementioned risks based on policy and risk preference.

The Company has established appropriate policies, procedures and internal controls for financial risk management. Before entering into significant financial activities, approval process by the Board of Directors and Audit Committee must be carried out based on related protocols and internal control procedures. The Company complies with its financial risk management policies at all times.

(3)	Market risk

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

Foreign currency risk

The Company's exposure to the risk of changes in foreign exchange rates relates primarily to the Company's operating activities (when revenue or expense is denominated in a different currency from the Company's functional currency) and the Company's net investments in foreign subsidiaries.

The Company applies natural hedges on the foreign currency risk arising from purchases or sales, and utilizes spot or forward exchange contracts to manage foreign currency risk and the net effect of the risks related to monetary financial assets and liabilities is minor. The notional amounts of the foreign currency contracts are the same as the amount of the hedged items. In principle, the Company does not carry out any forward exchange contracts for uncertain commitments. Furthermore, as net investments in foreign subsidiaries are for strategic purposes, they are not hedged by the Company.

The foreign currency sensitivity analysis of the possible change in foreign exchange rates on the Company's profit is performed on significant monetary items denominated in foreign currencies as of the end of the reporting period. When NTD strengthens/weakens against USD by 10%, the profit for the three-month periods ended March 31, 2022 and 2021 decreases/increases by NT$1,291 million and NT$1,467 million, respectively. When RMB strengthens/weakens against USD by 10%, the profit for the three-month periods ended March 31, 2022 and 2021 increases/decreases by NT$40 million and NT$1,423 million, respectively. When JPY strengthens/weakens against USD by 10%, the profit for the three-month periods ended March 31, 2022 and 2021 decreases/increases by NT$481 million and NT$274 million, respectively.

Interest rate risk

The Company is exposed to interest rate risk arising from borrowing at floating interest rates. All of the Company's bonds have fixed interest rates and are measured at amortized cost. As such, changes in interest rates would not affect the future cash flows. On the other hand, as the interest rates of the Company's short-term and long-term bank loans are floating, changes in interest rates would affect the future cash flows but not the fair value. Please refer to Note 6(11), 6(13) and 6(14) for the range of interest rates of the Company's bonds and bank loans.

At the reporting dates, a change of 10 basis points of interest rate in a reporting period could cause the profit for the three-month periods ended March 31, 2022 and 2021 to decrease/increase by NT$10 million and NT$12 million, respectively.

Equity price risk

The Company's listed and unlisted equity securities and exchange right of the exchangeable bonds issued are susceptible to market price risk arising from uncertainties about future performance of equity markets. The Company's equity investments are classified as financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income, while exchange right of the exchangeable bonds issued is classified as financial liabilities at fair value through profit or loss as it does not satisfy the definition of an equity component.

The sensitivity analysis for the equity instruments is based on the change in fair value as of the reporting date. A change of 5% in the price of the aforementioned financial assets at fair value through profit or loss of listed companies could increase/decrease the Company's profit for the three-month periods ended March 31, 2022 and 2021 by NT$397 million and NT$303 million, respectively. A change of 5% in the price of the aforementioned financial assets at fair value through other comprehensive income of listed companies could increase/decrease the Company's other comprehensive income for the three-month periods ended March 31, 2022 and 2021 by NT$769 million and NT$653 million, respectively.

Please refer to Note 12(7) for sensitivity analysis information of other equity instruments or derivatives that are linked to such equity instruments whose fair value measurement is categorized under Level 3.

(4)	Credit risk management

The Company only trades with approved and creditworthy third parties. Where the Company trades with third parties which have less credit, it will request collateral from them. It is the Company's policy that all customers who wish to trade on credit terms are subject to credit verification procedures. In addition, notes and accounts receivable balances are monitored on an ongoing basis to decrease the Company's exposure to credit risk.

The Company mitigates the credit risks from financial institutions by limiting its counter parties to only reputable domestic or international financial institutions with good credit standing and spreading its holdings among various financial institutions. The Company's exposure to credit risk arising from the default of counter-parties is limited to the carrying amount of these instruments.

As of March 31, 2022, December 31, 2021 and March 31, 2021, accounts receivable from the top ten customers represent 60%, 60% and 61% of the total accounts receivable of the Company, respectively. The credit concentration risk of other accounts receivable is insignificant.

(5)	Liquidity risk management

The Company's objectives are to maintain a balance between continuity of funding and flexibility through the use of cash and cash equivalents, bank loans, bonds and lease.

The table below summarizes the maturity profile of the Company's financial liabilities based on the contractual undiscounted payments and contractual maturity:

(7)	Fair value of financial instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either in the principal market for the asset or liability, or in the absence of a principal market, in the most advantageous market for the asset or liability.

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest.

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

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

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

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities;

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable;

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

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

Financial liabilities:
Financial liabilities at fair value through profit or loss, current	-	19,653	-	19,653

Fair values of financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income that are categorized into level 1 are based on the quoted market prices in active markets. If there is no active market, the Company estimates the fair value by using the valuation techniques (income approach and market approach) in consideration of cash flow forecast, recent fund raising activities, valuation of similar companies, individual company's development, market conditions and other economic indicators.

If there are restrictions on the sale or transfer of a financial asset, which are a characteristic of the asset, the fair value of the asset will be determined based on similar but unrestricted financial assets' quoted market price with appropriate discounts for the restrictions. To measure fair values, if the lowest level input that is significant to the fair value measurement is directly or indirectly observable, then the financial assets are classified as Level 2 of the fair value hierarchy, otherwise as Level 3.

During the three-month periods ended March 31, 2022 and 2021, there were no significant transfers between Level 1 and Level 2 fair value measurements.

Reconciliation for fair value measurement in Level 3 fair value hierarchy were as follows:

The total profit of NT$978 million and NT$203 million for the three-month periods ended March 31, 2022 and 2021, were included in profit or loss that is attributable to the change in unrealized gains or losses relating to those financial assets without quoted market prices held at the end of the reporting period.

The total profit of NT$1,002 million and nil for the three-month periods ended March 31, 2022 and 2021, were included in profit or loss that is attributable to the change in unrealized gains or losses relating to those financial liabilities without quoted market prices held at the end of the reporting period.

The Company's policy to recognize the transfer into and out of fair value hierarchy levels is based on the event or changes in circumstances that caused the transfer.

Significant unobservable inputs of fair value measurement in Level 3 fair value hierarchy were as follows:

b.	Assets and liabilities not recorded at fair value but for which fair value is disclosed:

The fair value of bonds payable is estimated by the market price or using a valuation model. The model uses market-based observable inputs including share price, volatility, credit spread and risk-free interest rates. The fair value of long-term loans is determined using discounted cash flow model, based on the Company's current incremental borrowing rates of similar loans.

The fair values of the Company's cash and cash equivalents, receivables, refundable deposits, other financial assets, short-term loans, payables and guarantee deposits approximate their carrying amount.

Note C： Please refer to Note 9(6) for more details on other financial liabilities.

(9)	Significant intercompany transactions among consolidated entities for the three-month periods ended March 31, 2022 and 2021 are disclosed in Attachment 1.

(10)	Capital management

The primary objective of the Company's capital management is to ensure that it maintains a strong credit rating and healthy capital ratios to support its business and maximize the shareholders' value. The Company also ensures its ability to operate continuously to provide returns to shareholders and the interests of other related parties, while maintaining the optimal capital structure to reduce costs of capital.

To maintain or adjust the capital structure, the Company may adjust the dividend payment to shareholders, return capital to shareholders, issue new shares or dispose assets to redeem liabilities.

Similar to its peers, the Company monitors its capital based on debt to capital ratio. The ratio is calculated as the Company's net debt divided by its total capital. The net debt is derived by taking the total liabilities on the consolidated balance sheets minus cash and cash equivalents. The total capital consists of total equity (including capital, additional paid-in capital, retained earnings, other components of equity and non-controlling interests) plus net debt.

The Company's strategy, which is unchanged for the reporting periods, is to maintain a reasonable ratio in order to raise capital with reasonable cost. The debt to capital ratios as of March 31, 2022, December 31, 2021 and March 31, 2021 were as follows:

	As of
	March 31, 2022	December 31, 2021	March 31, 2021
Total liabilities	$180,623,409	$183,223,887	$144,589,394
Less: Cash and cash equivalents	(172,170,231)	(132,622,131)	(107,285,177)
Net debt	8,453,178	50,601,756	37,304,217
Total equity	302,285,107	281,202,884	249,672,760
Total capital	$310,738,285	$331,804,640	$286,976,977
Debt to capital ratios	2.72%	15.25%	13.00%
