To Shareholders

Dear Shareholders, Ladies, and Gentlemen:

With the active efforts of all colleagues and the support of all shareholders, the Company’s overall consolidated operating VIII in 2019 reached a total of NT$35.83 billion, and the net income before tax reached NT$5.081 billion.

The 2021 Operational Outlook

(I) Business goals

The markets in Mainland China and Singapore remained unchanged in 2020, with a decrease in revenue to 6% from 19.5% in 2019. However, the overall revenue growth is still significant because the Taiwan market is growing greatly.

While the overseas market remained slow in 2021, the Taiwan market remained strong. However, due to the very large revenue recognized from the clients of Micron in 2020, the revenue grew significantly in that year. Therefore, we expect that 2021 will still be a very good year, but the revenue will be lower than 2020. We expect to reach a new high in 2022.

(II) Management policy and development strategy

For the purpose of the Company's long-term management and development, the Company will strengthen the internal management and also upgrade its competitiveness in cost, quality and technology significantly. Meanwhile, the Company will train more staff in the cross-strait and introduce related system elites. Especially, the Company needs to strengthen its business in Mainland China to prepare for the business growth in Mainland China. At present, in the Company’s professional field, although the revenue and competitiveness have been ahead of the peers, the Company will strive to enhance its operation this year and improve the construction method to reduce costs and increase profitability in order to increase market share and keep the competitors in the distance. In terms of products, the wireless security monitoring system department has achieved considerably, but research and development and business development must be further deepened.

(III) External competition, regulatory environment, and overall business environment impact

The Company's market share in the high-tech industry of Taiwan is increasing year by year, and the Company's competitors with scale and competitiveness are very limited. In the market of Mainland China, the competitors include the local companies, and peers from Taiwan and foreign countries. Therefore, the competition is considered more intensive in the market of Mainland China. However, the Chinese market is relatively large. The Company is a first-class brand with a competitive advantage comparing to the competitors. Therefore, the Company still has certain advantages to compete in the Chinese market.

The Company has developed the market in Singapore successfully in the past few years. This can help the Company's future development very much.

(II) Business Goals

(III) Important Production and Marketing Policies

Here at the Company, we, as always, have been focusing on the high-tech plant business for more than two decades. Amidst the cutthroat competition within the counterpart firms in the same industry, we have come out as relatively more outstanding. Further coupled with the rapid boom in the high-tech industry in recent years, our Company has been growing at a satisfactory pace. On the other hand, nevertheless, where our business has been excessively concentrated, we have been under both advantage and disadvantage. For a sound long-term development for our Company, we shall focus on developing the environmental protection and energy industry in the days and years ahead. Through such efforts, we hope to build another sound support point for our Company.

Five. Operational overview

I. Business content

(I) Business scope
The main business content and business ratio of the Company:
- (1) Main contents: The construction of semiconductor, optoelectronics and other technology plants; the consultancy work for cleanrooms, control, electromechanical, and special process system construction, design, and planning; and maintenance operation services.
- (2) Business ratio:

Businessratio:
Item	2019	2020
System integration	98.31%	99.42％
Maintenance service	0.21%	0.16％
Design business and product sales	1.48%	0.42％

(II) Industry overview

Current and future industry prospects:
(1) The Company has primarily engaged in such business lines as to serve the hightech industry in planning for plant construction and expansion, including the semiconductor industry, optoelectronics industry, packaging and testing industry, solar energy industry, LED industry, biotechnology industry and the like. Given the Company's revenue in the past five years, the aforementioned industries account for more than 90% of the Company's total revenues.
(2) While just last year, Taiwan's high-tech industry was highly enthusiastic about building new plants while Mainland China's counterparts were less enthusiastic. With more competitors joining the competition, our revenue decreased from the preceding year. After the sum up, anyway, the entire year's performance still hit an all time high.
(3) The enthusiasm to build new plants in Taiwan's high-tech industries remains pretty high this year and next. While revenues recognized in Micron's large-scale projects will decline in the present year, the overall revenue would inevitably decline slightly this year. Still, we see another chance to hit another all time high next year.
Relevance of the up, middle and downstream amidst industries: Our Company undertakes system integration services for the construction of high-tech plants. For that purpose, we must possess the technology and sufficient management workforce. In terms of suppliers including subcontracting manufacturers and suppliers for materials and equipment, we possess multiple supply sources and are virtually free of the risk of being cut off from or insufficient supply. Toward the price increase of materials and the shortage of skilled workers with special expertise, nevertheless, we must try hard in prevention with sound educational & training programs so that we may be free of problems in mounting costs and shortage of workforce.
Product development trend and competition:
(1) The whole plant construction services will become a very natural trend in the future. Our company is one of very few capable manufacturers in our country and our primary competitors are Maister and L&K Engineering Co., Ltd.
(2) In terms of clean room integration services, amidst the weakening of the

~ 107 ~

competitiveness of foreign manufacturers, our market share of the has boosted significantly. Other competitors include L&K Engineering Co., Ltd., Maister, Acter Co. Ltd. and Yankey Engineering Co., Ltd..

  - (3) The electromechanical integration service is attributed to local characteristics and, in turn, is less subject to foreign competition. In this regard, our Company is in a leading position. Primary competitors are L&K Engineering Co., Ltd., Acter Co. Ltd., and Yankey Engineering Co., Ltd..

  - (4) The Hook-UP Project is divided into multiple professional systems where all systems are formidable competitors. Our Company is more competitive in the power and PCW professions.

The impact incurred by the coronavirus pandemic (COVID-19) upon the Company. Those projects being in progress in Taiwan have not been subject to an impact so far. Those projects in Mainland China have been delayed, in particular the project site at Wuhan. Luckily the order has not been cancelled, notwithstanding the delay. Where the Company's major revenues come within Taiwan in the present year, there would not be a too significant impact upon our overall revenues.
(III) Technology and R&D overview
R&D expenses invested in the last two years and as of December 31, 2020:

			Unit: NT$ Thousands % of current annual operating income 0.1467% 0.0969%
Year	R&D expense	% of current annual operating expense	% of current annual operating income
108	35,100	3.7184%	0.1467%
109	34,723	3.2649%	0.0969%

Research and development achievement:
(1) Continuing to develop wireless home security monitoring system that helps make the overall system more complete.
(IV) Long-term and short-term business development plans:
In the short term, the business opportunities in market will grow to a certain extent, and the Company’s revenue will also grow. Under this circumstance, it is also necessary to strengthen internal management, reduce costs, train cadres, upgrade technology, and perform customer service work to meet future challenges.
In the long run, we will deepen the integration of high-tech factory systems on both sides of the strait and strengthen the markets outside the two sides of the strait, making the Company the largest system integration service provider on both sides of the strait and becoming a world-class company.
In response to TSMC's establishment of a factory in the United States, our Company sets up a new firm in the United States to vigorously boost.
We shall set up a Green Energy Business Office to put forth maximum possible efforts to develop solar photovoltaic-related businesses.
The wireless security monitoring product R&D will be enhanced. Wireless security monitoring businesses had begun to become profitable. In the future, we will try our best to expand the market share and to increase turnover and profit.

2. Future market supply and demand:

－－ Taiwan

Taiwan has held a leading position in the global semiconductor and optoelectronics industry, making it a two-industry powerhouse that is a point of pride for Taiwan. This industry has the characteristics of either advancing or retreating; therefore, it must continue to maintain its leading position in process enhancement and expansion of production capacity. In the long run, it provides the base for the stable development of the Company.

－－ Mainland China

China has invested heavily in the semiconductor and panel industry, which will become the main business opportunity for the Company’s growth.

Business objectives

The Company has based on the business philosophy of “profession, teamwork, and efficiency” to accumulate technical experience for more than a decade, cultivate and recruit outstanding talents in related fields; also, has established a reputation of professionalism and quality in the industry. The trust and affirmation of customers has helped the business of the Company grow. The continuous management improvement will help reduce operating costs and enhance profitability of the Company. Given the gradual expansion of market demand, the established business objectives could be ensured.

(2) The Company is in a leading position in business performance and has easily obtained customer trust and government engineering bidding qualifications to win over businesses.

~ 109 ~

(3) In a large-scale and complex integration project, there are not many domestic competitors who can compete. If competitors are foreign manufacturers, the Company has the advantages of familiarity with local operating environment, local relevant regulations, and local low-cost technology and management.
(4) Taiwanese businesspeople in Mainland China are more experienced in the high-tech industry because they share the same culture and background as the mainlanders. Therefore, they retain certain competitiveness.
(5) The Company has an experienced technical and management team with low operational risks for difficult projects.

Disadvantages

  - (1) The experience of the owners in building factories is increasingly established and the effort in cost control is maturing. It is not easy to have a high profit margin while price competition is severe. In particular, the recent sharp rise in raw materials, workforce shortages and such rising prices will become an impact. In this regard, the Company has been working hard to improve and upgrade its procurement, management, technology, construction methods, and in-house processing improvements; therefore, this unfavorable factor can be minimized.

Retirement system:

The Company has offered a labor retirement plan stipulated for all official employees. According to the said retirement plan, the payment of employee pension is calculated according to the pension points earned for the service years and the average salary of the six months before retirement. The pension points are the total of 2 points per year for the first 15 service years and 1 point per year after the fifteen service year with a maximum of 45 points per employee. Under the said retirement plan, the pension payment is fully borne by the Company. With the implementation of the Labor Pensions Act (hereinafter referred to as the “New Pension Plan”) since July 1, 2005, for the employees who originally subject to this retirement plan choose to switch to the defined contribution plan for the service years performed after the application of the new retirement plan or the service years of the new recruits, the pension reserve is appropriated by the Company monthly for an amount no less than 6% of the monthly salary, which is deposited in the personal labor pension account. However, the Company’s retirement plan has not been amended in compliance with the new pension act, so the employee retirement plan that is not stipulated should be processed according to the provisions of the Labor Pension Act.

The agreement between the employer and employees and various employee rights protection measures:

The Company has a comprehensive system in place to maintain a harmonious labormanagement relationship and a smooth communication channel maintained. The Company has properly handled the opinions of employees, if any, through the maintenance of a harmonious labor-management relationship.

In addition, the Company will strengthen the follow-up and supervision of the financial and business conditions of the invested company. If the invested company is not performing as well as when it was originally invested and there is no sign of improvement, the Company does not rule out the possibility of changing long-term investment policies and will choose to have the shares disposed. The investment projects that are carried out to increase business opportunities will be sold at an appropriate time to recover the funds for better overall use.

VI. Risk management analysis and evaluation

(I) The impact of interest rates, changes in exchange rate, and inflation on the Company’s profit and loss in the most recent year and as of the annual report printing date, and the countermeasures in the future:

Compared with other companies, the Company enjoys a better interest rate. Therefore, changes in interest rate have no significant impact on the Company.

In this regard, the countermeasures of the Finance Office are with the exchange rate trend considered, if necessary, the operating procedures for derivative financial products are applied to operate options or forward foreign exchange transactions for a fixed exchange rate in order to avoid risks.

Main Content of the Judgment

==> picture [51 x 10] intentionally omitted <==

used for repaying several incidental payments (collectively referred to as the “Package Fees”), previously paid by Dentsu and other companies. There is also no evidence provided that the defendants had committed an offence involving embezzlement or breach of trust; therefore, the court considers that the defendants were not guilty of each of the above-mentioned criminal charge. However, the court still held the defendants guilty for financial statement fraud due to failure to disclose in the financial statements of Dentsu and other companies and the Package Fees thereof. The defendants all appealed against the conviction while the public prosecutor also filed an appeal against the acquittal part of the verdict; and due to the death of Mr. Wang, the former Chairman of the Company, the High Court (No. 104 Jin-Shang-Chung-Su-Tzu 40) declared a dismissal judgment for Mr. Wang on July 25, 2017 with respect to the charges of non-arm's length transactions, breach of trust, and embezzlement. The High Court stated that there was no evidence to prove that the defendants, other than Mr. Wang, were guilty and the public prosecutor accepted the acquittal judgment without further appeal. As for the High Court's decision of guilty on the financial statement fraud, the sentences on two of the defendants were finalized because they were given probations and decided not to appeal; while Chairman Chen appealed to the Supreme Court, wherein the Supreme Court (No. 106 Tai-Shang-Tzu 3336), on July 25, 2018, reversed and remanded the case to the High Court whose further judgment (No. 107 Jin-Shang-Chung-Geng-Yi-Tzu 8) on December 10, 2019 sentenced Mr. Chen guilty for misrepresented financial statements for certain years and guilty for violations of the Business Entity Accounting Act, as well as a five-year probation; Chairman Chen filed an appeal while the SFIPC center also requested the prosecutor to appeal. The Supreme Court reversed and remanded the case to the High Court on July 17, 2020, moving the case for further proceedings in the High Court.

2. Corresponding Measures

~ 138 ~

Wang's loyalty and confidence in the Company; Chairman Chen has assisted with matters of the Company for decades and has worked hard for the Company. Owing to the contributions of both of them, the Company has thrived and has been able to consistently make stable profits. Therefore, we feel grateful that the investigation by the first and second instance courts and the retrial court resulting in the opinions of the court that the assertions of non-arm's length transactions, breach of trust and embezzlement as indicted by the prosecutor are not true. It is regrettable that the court still considers that the financial reports of certain fiscal years are misrepresented. As the Supreme Court has reversed and remanded the case to the High Court, the Company will await the final judgment.

3. Impact on the Operations

Since the occurrence of this case, the staff of the Company altogether have continued to stay on their posts and serve customers. The Company has also received support from proprietors and third-party firms. The Company's revenue continues to grow, while the progress, collection and payment operations of projects remain normal. Current business and finances of the Company are quite robust, as the Company's operations have not been affected by any of the judicial events.

On December 5, 2013, based on the contents of the indictment, the SFIPC argued that it was inappropriate for the former three directors to hold such positions in the Company and appealed for court decision to dismiss the directors' positions.

==> picture [51 x 10] intentionally omitted <==

petition to be dismissing two directors' positions from June 16, 2015 to June 15, 2018. The court of Second Instance decided in early February 2016 to dismiss the complaint of the SFIPC about changes of claims. The SFIPC appealed to the Court of Third Instance on March 28, 2016. The Supreme Court (No. 106 Tai-Shang-Tzu 2658) revoked the original Second Instance judgment on September 28, 2018, and remanded the case to the High Court. On April 28, 2020, the two directors were disqualified from being a director by the High Court order. Both directors filed appeals on May 18, 2020, but due to the resignation of director Lee on June 2, 2020, she withdrew the appeal on June 3 in the same year and the court's decision on director Lee became finalized as of the date thereof; while the appeal part regarding director Chen is currently under the trial of the Supreme Court. The financial and business operations of the Company have also not been affected by this lawsuit.

According to the content of the indictment on January 27, 2014, the SFIPC filed a group lawsuit on behalf of the investor on the grounds that the Company's financial reports from the third quarter of 2008 to 2011 were misrepresented, requesting the Company, directors and former supervisors to jointly compensate the investors for the damage amounting to more than NT$243 million.

As stated above, the Company's operations and financial position have always been sound, and its share price has remained at a considerable level. It has been a stable and profitable Company for a long time. Relevant parties have also indicated that the Company has handled the affairs of the Company's interests and has not caused the Company's financial reports to be misrepresented. The judgment of the criminal first retrial court also holds that even though the Company's financial reports and financial business documents between years 2008 and 2011 were indeed misrepresented and have not reached materiality criteria, they have only violating the Business Accounting Laws regulations. As the Supreme Court reversed and remanded the case to the High Court, the case remains for further proceedings in the High Court. Before the criminal case and the final judgment of this civil action are determined, whether the Company has misrepresented financial reports in the past years stated, the investors have been harmed, or the damage is related to false financial reporting, etc., it would take a period of time before the judgment is announced. This lawsuit has also not affected the normal

~ 140 ~

operation of the Company's current financial business.

(III) The Company received the civil judgment from the Taiwan Taipei District Court on September 2, 2014 that the Company should pay the package fees of $104,559 thousand and the former Chairman Wang's salary from January 2001 to April 2012, as previously paid by Dentsu, amounting to $21,405 thousand.

In the third quarter of 2014, in accordance with the judgment stated above, the Company assessed and took into accounts the package fees and salary paid by Dentsu, which have yet to be reimbursed by the Company (respectively logged as construction costs and management costs). The Company also estimated that the relevant interest payable as of December 31, 2019 amounted to $40,517 thousand (please refer to note 7).

As of the reporting date, the Company has yet to reimburse the abovementioned package fees, salary and related interests.

(IV) On September 5, 2016, Jiangxi United Integrated Services Ltd. (“Jiangxi UIS”) and Fujian Mantix Display Technology Co. Ltd. (“Fujian Mantix”) have executed the “Clean City Subcontract A Turn-Key Agreement” for the “Phrase I Project of the Fujian Mantix High-Tech Panel Construction” (“Project”) in Hanjiang District, Putian City, and have subsequently executed four supplemental agreements, including the “Electrical and Mechanical Installation Project of Section A” and the “Light Current System Installation Project”. Jiangxi UIS had performed all of the obligations arising from the abovementioned agreements; while Fujian Mantix accepted and put the Project into operation for which warranty coverage has expired but failed to make payments amounting to CNY 27,303 thousand pursuant to the Agreements. On April 23, 2020, Jiangxi UIS filed a lawsuit to recover the unpaid fees and relevant interest and applied for an asset preservation order in the Fujian Putian Middle Class People's Court (“People's Court”). On June 5, 2020, the People's Court ordered to freeze Fujian Mantix's certain bank accounts within a certain range of deposit amounts. A meditated settlement agreement (“Settlement”) was reached between the parties subsequently and was approved by the People's Court on September 28, 2020. Pursuant to the Settlement, the parties agreed that the total sum of the unpaid amount shall be CNY 28,000 thousand (“Settlement Amount”). The Settlement Amount shall be paid in 7 installments commencing on October 31, 2020 with the last payments due on April 30, 2021, and if

~ 141 ~

Fujian Mantix fails to pay on time, the total sum of the payment will be restored back to amount recognized by the parties amounting to CNY 27,301 thousand plus the interest of CNY 1,200 thousand.

As of December 31, 2020, Fujian Mantix has yet to receive the abovementioned payments amounting to CNY 10,646 thousand (equivalent to NTD 46,600 thousand). The consolidated company conducted relevant assessments and recognized that the allowance for loss regarding the abovementioned payments is CNY 3,237 thousand (equivalent to NTD 14,168 thousand) by December 31, 2020.

(XIII) Other important risks and countermeasures:

Assessment and analysis of information security risk: No significant risks. VII. Other important matters: None.

We have audited the consolidated financial statements of United Integrated Services Co., Ltd. and its Subsidiaries ("the Group"), which comprise the consolidated balance sheets as of December 31, 2020 and 2019 and the consolidated statements of comprehensive income, changes in equity and cash flows for the years then ended, and notes to the consolidated financial statements, including a summary of significant accounting policies.

In our opinion, based on our audits and the reports of other auditors (please refer to Other Matter section), the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group as of December 31, 2020 and 2019, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and with the International Financial Reporting Standards (“IFRSs”), International Accounting Standards (“IASs”), Interpretations developed by the International Financial Reporting Interpretations Committee (“IFRIC”) or the former Standing Interpretations Committee (“SIC”) endorsed and issued into effect by the Financial Supervisory Commission of the Republic of China.

Basis for Opinion

We conducted our audits in accordance with the Regulations Governing Auditing and Certification of Financial Statements by Certified Public Accountants and the auditing standards generally accepted in the Republic of China. Our responsibilities under those standards are further described in the Auditors' Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Group in accordance with the Certified Public Accountants Code of Professional Ethics in Republic of China ("the Code"), and we have fulfilled our other ethical responsibilities in accordance with the Code. Based on our audits and the reports of other auditors, we believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis of our opinion.

Emphasis of Matter

Some board members of United Integrated Services Co., Ltd. were sentenced of violating the Securities Exchange Act by the Taiwan High Court. For circumstances of these cases, please refer to Note12 (b) of the consolidated financial statements. Our opinion is not modified in respect of this matter.

~ 149 ~

Other Matter

We did not audit the financial statements of investee companies under the equity method and certain information of Note 13 (b) "Information on investees of the consolidated financial statements". Those statements were audited by other auditors, whose reports have been furnished to us, and our opinion, insofar as it relates to the amounts included for these investee companies, is based solely on the reports of other auditors. The investments in the investee companies constituted 3.14% and 3.63% of the consolidated total assets, as of December 31, 2020 and 2019, respectively. For the years then ended, the recognized shares of profit of associates accounted for using the equity method of these investee companies constituted 1.01% and 1.26% of the consolidated total profit before tax, respectively.

United Integrated Services Co., Ltd. has additionally prepared its parent-company-only financial statements as of and for the years ended December 31, 2020 and 2019, on which we have issued an unmodified opinion with the Emphasis of Matter or Other Matter paragraph.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as a whole and in forming our opinion thereon, and we do not provide a separate opinion on these matters. In our judgment, the key audit matters we communicated in the auditors' report were as follows:

1. Revenue recognition

For the accounting policies related to revenue recognition, please refer to Note 4 (o) "Revenue recognition"; for uncertainty of accounting estimates and assumption for revenue recognition, please refer to Note 5 (b) "Revenue recognition"; for information of revenue recognition, please refer to Note 6 (u) "Revenue from contracts with customers" to the consolidated financial statements.

Description of Key Audit Matter:

The Group recognizes construction contract revenue by percentage of completion method. The percentage of completion is based on the contract costs incurred as of the financial statements reporting date, representing the percentage of the estimated total contract costs. Because construction contract accounting involves a high level of estimation and judgment, revenue recognition has been identified as one of the key audit matters for our audit.

How the matter was addressed in our audit:

In relation to the key audit matter above, our principal audit procedures included testing the effectiveness of the internal control related to the timing and precision of revenue recognition. Through sampling and reviewing new construction contracts and related documents throughout the Group's reporting period, we obtained annual project revenue statistics and validated the correctness of revenue recognized on the projects.

~ 150 ~

2. Accounts receivable impairment assessment

For the accounting policies related to the impairment assessment of accounts receivable, please refer to Note 4 (g) "Financial instruments"; for uncertainty of accounting estimates and assumption for the impairment assessment of accounts receivable, please refer to Note 5 (a) "Impairment assessment of accounts receivable"; for information of the impairment assessment of accounts receivable, please refer to Note 6 (c) "Notes and accounts receivable" to the consolidated financial statements.

Description of Key Audit Matter:

The Group recognized expected credit loss in accordance with the Group's policy of allowance for accounts receivable, and established its estimation based on its clients' credit risk, historical experiences of credit loss, and rational expectation of future economic conditions. Since the accounting of expected credit loss of accounts receivable involves a high level of estimation and judgment, the impairment assessment of accounts receivable has been identified as one of the key audit matters for our audit.

How the matter was addressed in our audit:

In relation to the key audit matter above, our principal audit procedures included: (i) understanding the accounting policies of the impairment assessment of notes and trade receivables; (ii) implementing sampling procedures to examine the accuracy of accounts receivable aging report; (iii) analyzing the changes of the aging of accounts receivable in each period; (iv) examining historical collection records; (v) examining subsequent collection status to evaluate the reasonableness of the Group's recognition of allowance for impairment loss.

3. Financial instruments assessment

For the accounting policies related to the assessment of financial instruments, please refer to Note 4 (g) "Financial Instruments"; for uncertainty of accounting estimates and judgments for fair value of financial instruments, please refer to Note 5 (c) "Fair value of financial instruments"; for information of the fair value of financial instruments, please refer to Note 6 (x) "Fair value hierarchy information" to the consolidated financial statements.

Description of Key Audit Matter:

The accounting of the assessment of financial instruments involves a high level of estimation and judgment. Therefore, the assessment of financial instruments has been identified as one of the key audit matters for our audit.

How the matter was addressed in our audit:

In relation to the key audit matter above, our principal audit procedures included: (i) testing the investment cycle and related financial reporting procedures, involving measurements and the internal control of financial reporting disclosures. (ii) assessing the reasonableness of valuation techniques of the financial assets measured at fair value without active market prices, including testing valuation models and inspecting the significant unobservable inputs to ensure that the applied valuation techniques were in accordance with IFRS 13 “Fair Value Measurement”.

~ 151 ~

Responsibilities of Management and Those Charged with Governance for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and with the IFRSs, IASs, IFRIC, SIC endorsed and issued into effect by the Financial Supervisory Commission of the Republic of China, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, the management is responsible for assessing the Group's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the management either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.

Those charged with governance (including the Audit Committee) are responsible for overseeing the Group's financial reporting process.

Auditors' Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors' report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the auditing standards generally accepted in the Republic of China will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with auditing standards generally accepted in the Republic of China, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group's internal control.

Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and

~ 152 ~

related disclosures made by the management.

Conclude on the appropriateness of the management's use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors' report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditors' report. However, future events or conditions may cause the Group to cease to continue as a going concern.
Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

~ 153 ~

Obtain sufficient and appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditors' report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partners on the audit resulting in this independent auditors’ report are Tzu-Hui, Lee and Jung-Lin, Lee.

(b) The impact of IFRS issued by the FSC but not yet effective

The Group assesses that the adoption of the following new amendments, effective for annual period beginning on January 1, 2021, would not have a significant impact on its consolidated financial statements:

Amendments to IFRS 4 “Extension of the Temporary Exemption from Applying IFRS 9”
－
● Amendments to IFRS 9, IAS39, IFRS7, IFRS 4 and IFRS 16 “Interest Rate Benchmark Reform Phase 2”
(c) The impact of IFRS issued by IASB but not yet endorsed by the FSC

The following new and amended standards, which may be relevant to the Group, have been issued by the International Accounting Standards Board (IASB), but have yet to be endorsed by the FSC:

Standards or Interpretations Amendments to IFRS 10 and IAS 28 “Sale or Contribution of Assets Between an Investor and Its Associate or Joint Venture”	Content of amendment The amendments address an acknowledged inconsistency between the requirements in IFRS 10 and those in IAS 28 (2011) in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business (whether it is housed in a subsidiary or not). A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary.	Effective date per IASB
		Effective date to be determined by IASB

Amendments to IAS 37 The amendments clarify that the ‘costs of January 1, 2022 － “Onerous Contracts Cost of fulfilling a contract' comprises the costs that Fulfilling a Contract” relate directly to the contract as follows:

● the incremental costs – e.g. direct labor and materials; and

● an allocation of other direct costs – e.g. an allocation of the depreciation charge for an item of property, plant and equipment used in fulfilling the contract.

The Group is evaluating the impact of its initial adoption of the abovementioned standards or interpretations on its consolidated financial position and consolidated financial performance. The results thereof will be disclosed when the Group completes its evaluation.

(4) Summary of significant accounting policies

The significant accounting policies presented in the consolidated financial statements are summarized below. Except for those specifically indicated, the following accounting policies were applied consistently throughout the periods presented in the consolidated financial statements.

(a) Statement of compliance

These consolidated financial statements have been prepared in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers (hereinafter referred to as “the Regulations”) and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations endorsed and issued into effect by the Financial Supervisory Commission, R.O.C..

(b) Basis of preparation

Except for the following significant accounts, the consolidated financial statements have been prepared on a historical cost basis:

1) Financial instruments measured at fair value through profit or loss are measured at fair value;
2) Financial assets measured at fair value through other comprehensive income are measured at fair value;
3) The defined benefit liabilities are measured at fair value of the plan assets less the present value of the defined benefit obligation.
(ii) Functional and presentation currency

(c) Basis of consolidation
(i) Principles of preparation of consolidated financial statements

The consolidated financial statements comprise the Company and subsidiaries. The financial statements of the subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases. Intragroup balances and transactions, and any unrealized income and expenses arising from Intragroup transactions, are eliminated in preparing the consolidated financial statements. The Group attributes the profit or loss and each component of other comprehensive income to the owners of the parent and to the non-controlling interests, even if this results in the non-controlling interests having a deficit balance.

When necessary, adjustments are made to the financial statements of the subsidiaries to bring their accounting policies into line with those used by the Group.

Changes in the Group's ownership interest in a subsidiary that do not result in the loss of control are accounted for as equity transactions.

(d) Foreign currencies
(i) Foreign currency transactions

Transactions in foreign currencies are translated into the respective functional currencies of Group entities at the exchange rates at the dates of the transactions. At the end of each subsequent reporting period, monetary items denominated in foreign currencies are translated into the functional currencies using the exchange rate at that date. Non-monetary items denominated in foreign currencies that are measured at fair value are translated into the functional currencies using the exchange rate at the date that the fair value was determined. Non-monetary items denominated in foreign currencies that are measured based on historical cost are translated using the exchange rate at the date of the transaction.

Exchange differences are generally recognized in profit or loss, except for those differences relating to the following, which are recognized in other comprehensive income:

1) an investment in equity securities designated as at fair value through other comprehensive income;
2) a financial liability designated as a hedge of the net investment in a foreign operation to the extent that the hedge is effective; or
3) qualifying cash flow hedges to the extent that the hedges are effective.
(ii) Foreign operations

The assets and liabilities of foreign operations, including goodwill and fair value adjustments arising on acquisition, are translated into the presentation currency at the exchange rates at the reporting date. The income and expenses of foreign operations are translated into the presentation currency at the average exchange rate. Exchange differences are recognized in other comprehensive income.

(Continued)

~ 164 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

When a foreign operation is disposed of such that control, significant influence, or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal. When the Group disposes of only part of its interest in a subsidiary that includes a foreign operation while retaining control, the relevant proportion of the cumulative amount is reattributed to non-controlling interests. When the Group disposes of only part of its investment in an associate or joint venture that includes a foreign operation while retaining significant influence or joint control, the relevant proportion of the cumulative amount is reclassified to profit or loss.

When the settlement of a monetary receivable from or payable to a foreign operation is neither planned nor likely to occur in the foreseeable future, Exchange differences arising from such a monetary item that are considered to form part of the net investment in the foreign operation are recognized in other comprehensive income.

(e) Classification of current and non-current assets and liabilities
(i) An asset is classified as current under one of the following criteria, and all other assets are classified as non-current.
1) It is expected to be realized, or intended to be sold or consumed, in the normal operating cycle;
2) It is held primarily for the purpose of trading;
3) It is expected to be realized within twelve months after the reporting period; or
4) The asset is cash or a cash equivalent (as defined in IAS 7) unless the asset is restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period.
(ii) A liability is classified as current under one of the following criteria, and all other liabilities are classified as non-current.

An entity shall classify a liability as current when:

1) It is expected to be settled in the normal operating cycle;
2) It is held primarily for the purpose of trading;
3) It is due to be settled within twelve months after the reporting period; or
4) The Group does not have an unconditional right to defer settlement of the liability for at least twelve months after the reporting period. Terms of a liability that could, at the option of the counterparty, result in its settlement by issuing equity instruments do not affect its classification.

Notes to the Consolidated Financial Statements

(iii) Other

The Group is mainly engaged in the planning, designation and construction contracting of various projects. Its business cycle is about three to five years. Due to assets and liabilities related to the engineering business, are based on operating cycle as the standard for dividing current or non-current.

(f) Cash and cash equivalents

Cash comprises cash on hand and demand deposits. Cash equivalents are short term, highly liquid investments that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in fair value. The definition of time deposit within 3 months is similar to that of cash equivalent; however, the purpose of holding time deposit is for short term cash commitment rather than investment.

(g) Financial instruments
(i) Financial assets

On initial recognition, a financial asset is classified as measured at: amortized cost; FVOCI – equity investment; or FVTPL. Financial assets are not reclassified subsequent to their initial recognition unless the Group changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model.

1) Financial assets measured at amortized cost

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:

‧ it is held within a business model whose objective is to hold assets to collect contractual cash flows; and
‧ its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

These assets are subsequently measured at amortized cost, which is the amount at which the financial asset is measured at initial recognition, plus/minus, the cumulative amortization using the effective interest method, adjusted for any loss allowance. Interest income, foreign exchange gains and losses, as well as impairment, are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss.

2) Fair value through other comprehensive income (FVOCI )

On initial recognition of an equity investment that is not held for trading, the Group may irrevocably elect to present subsequent changes in the investment's fair value in other comprehensive income. This election is made on an instrument-by-instrument basis.

(Continued)

~ 166 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

Equity investments at FVOCI are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in other comprehensive income and are never reclassified to profit or loss.

Dividend income is recognized in profit or loss on the date on which the Group's right to receive payment is established.

3) Fair value through profit or loss (FVTPL)

All financial assets not classified as amortized cost or FVOCI described as above are measured at FVTPL. On initial recognition, the Group may irrevocably designate a financial asset, which meets the requirements to be measured at amortized cost or at FVOCI, as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

These assets are subsequently measured at fair value. Net gains and losses, including any interest or dividend income, are recognized in profit or loss.

4)

Business model assessment

The Group makes an assessment of the objective of the business model in which a financial asset is held at portfolio level because this best reflects the way the business is managed and information is provided to management. The information considered includes:

‧ the stated policies and objectives for the portfolio and the operation of those policies in practice. These include whether management's strategy focuses on earning contractual interest income, maintaining a particular interest rate profile, matching the duration of the financial assets to the duration of any related liabilities or expected cash outflows or realizing cash flows through the sale of the assets;

‧ how the performance of the portfolio is evaluated and reported to the Group's management;
‧ the risks that affect the performance of the business model (and the financial assets held within that business model) and how those risks are managed;
‧ the frequency, volume and timing of sales of financial assets in prior periods, the reasons for such sales and expectations about future sales activity.

Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales for this purpose, and are consistent with the Group's continuing recognition of the assets.

Financial assets that are held for trading or are managed and whose performance is evaluated on a fair value basis are measured at FVTPL.

(Continued)

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

5) Impairment of financial assets

The Group recognizes loss allowances for expected credit losses (ECL) on financial assets measured at amortized cost (including cash and cash equivalents, notes and accounts receivable, other receivable, guarantee deposit paid and other financial assets), debt investments measured at FVOCI, accounts receivable and contract assets.

Loss allowance for trade receivables and contract assets are always measured at an amount equal to lifetime ECL.

Lifetime ECLs are the ECLs that result from all possible default events over the expected life of a financial instrument.

The maximum period considered when estimating ECLs is the maximum contractual period over which the Group is exposed to credit risk.

When determining whether the credit risk of a financial asset has increased significantly since initial recognition and when estimating ECL, the Group considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes both quantitative and qualitative information and analysis based on the Group's historical experience and informed credit assessment as well as forward-looking information.

The Group considers a financial asset to be in default when the financial asset is more than a year past due, or the debtor is unlikely to pay its credit obligations to the Group in full.

ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e the difference between the cash flows due to the Group in accordance with the contract and the cash flows that the Group expects to receive). ECLs are discounted at the effective interest rate of the financial asset.

At each reporting date, the Group assesses whether financial assets carried at amortized cost and debt securities at FVOCI are credit-impaired. A financial asset is ‘credit-impaired' when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Evidence that a financial asset is credit-impaired includes the following observable data:

‧ significant financial difficulty of the borrower or issuer;
‧ a breach of contract such as a default or being more than a year past due;
‧ the disappearance of an active market for a security because of financial difficulties.

Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets.

(Continued)

~ 168 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

The gross carrying amount of a financial asset is written off when the Group has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof. For corporate customers, the Group individually makes an assessment with respect to the timing and amount of write-off based on whether there is a reasonable expectation of recovery. The Group expects no significant recovery from the amount written off. However, financial assets that are written off could still be subject to enforcement activities in order to comply with the Group's procedures for recovery of amounts due.

6) Derecognition of financial assets

The Group derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which the Group neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset.

The Group enters into transactions whereby it transfers assets recognized in its statement of balance sheet, but retains either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized.

(ii) Financial liabilities

1) Financial liabilities

Other financial liabilities are subsequently measured at amortized cost using the effective interest method. Interest expense and foreign exchange gains and losses are recognized in profit or loss. Any gain or loss on derecognition is also recognized in profit or loss.

2) Derecognition of financial liabilities

The Group derecognizes a financial liability when its contractual obligations are discharged or cancelled, or expire. The Group also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

On derecognition of a financial liability, the difference between the carrying amount of a financial liability extinguished and the consideration paid (including any non-cash assets transferred or liabilities assumed) is recognized in profit or loss.

3) Offsetting of financial assets and liabilities

Financial assets and financial liabilities are offset and the net amount presented in the statement of balance sheet when, and only when, the Group currently has a legally enforceable right to set off the amounts and it intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously.

(Continued)

~ 169 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

(h) Inventories

The cost of inventories consists of all costs of purchase, conversion, and other costs incurred in bringing the inventories to their present location and condition. The cost of inventories includes an appropriate share of fixed production overhead based on normal capacity and allocated variable production overhead based on actual output. However, unallocated fixed production overhead arising from lower or idle capacity is recognized in cost of goods sold during the period. If actual capacity is higher than normal capacity, fixed production overhead should be allocated based on actual capacity. The method of valuing inventories is the weighted average method.

Inventories are measured at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and selling expenses at the end of the period. When the cost of inventories is higher than the net realizable value, inventories are written down to net realizable value, and the write down amount is charged to current year's cost of goods sold. If net realizable value increases in the future, the cost of inventories is reversed within the original write down amount, and such reversal is treated as a reduction of cost of goods sold.

(i) Investment in associates

Associates are those entities in which the Group has significant influence, but not control or joint control, over their financial and operating policies.

Investments in associates are accounted for using the equity method and are recognized initially at cost. The cost of the investment includes transaction costs. The carrying amount of the investment in associates includes goodwill arising from the acquisition less any accumulated impairment losses.

The consolidated financial statements include the Group's share of the profit or loss and other comprehensive income of those associates, after adjustments to align their accounting policies with those of the Group, from the date on which significant influence commences until the date on which significant influence ceases. The Group recognizes any changes of its proportionate share in the investee within capital surplus, when an associate's equity changes due to reasons other than profit and loss or comprehensive income, which did not result in changes in actual significant influence.

Gains and losses resulting from transactions between the Group and an associate are recognized only to the extent of unrelated Group's interests in the associate.

When the Group's share of losses of an associate equals or exceeds its interests in an associate, it discontinues recognizing its share of further losses. After the recognized interest is reduced to zero, additional losses are provided for, and a liability is recognized, only to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of the associate.

(j) Property, plant and equipment

(i) Recognition and measurement

Items of property, plant and equipment are measured at cost, which includes capitalized borrowing costs, less accumulated depreciation and any accumulated impairment losses.

If significant parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment.

(Continued)

~ 170 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES

Notes to the Consolidated Financial Statements

Any gain or loss on disposal of an item of property, plant and equipment is recognized in profit or loss.

(ii) Subsequent expenditure

Subsequent expenditure is capitalized only if it is probable that the future economic benefits associated with the expenditure will flow to the Group.

(iii) Depreciation

Depreciation is calculated on the cost of an asset less its residual value and is recognized in profit or loss on a straight-line basis over the estimated useful lives of each component of an item of property, plant and equipment.

Land is not depreciated.

The estimated useful lives of property, plant and equipment for current and comparative periods are as follows:

are as follows:
Buildings	5~50 years
Machinery	3~7 years
Plant equipment	3~50 years
Transportation equipment	3~7 years
Office equipment	3~10 years
Leasehold improvements	5 years

Depreciation methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

(k) Leases
(i) Identifying a lease

At inception of a contract, the Group assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Group assesses whether:

1) the contract involves the use of an identified asset – this may be specified explicitly or implicitly, and should be physically distinct or represent substantially all of the capacity of a physically distinct asset. If the supplier has a substantive substitution right, then the asset is not identified; and
2) the customer has the right to obtain substantially all of the economic benefits from use of the asset throughout the period of use; and

(Continued)

~ 171 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES

Notes to the Consolidated Financial Statements

3) the customer has the right to direct the use of the asset throughout the period of use only if either:
- the customer has the right to direct how and for what purpose the asset is used throughout the period of use; or
- the relevant decisions about how and for what purpose the asset is used are predetermined and:
  - － the customer has the right to operate the asset throughout the period of use, without the supplier having the right to change those operating instructions; or
  - － the customer designed the asset in a way that predetermines how and for what purpose it will be used throughout the period of use.
(ii) As a lessee

The Group recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be reliably determined, the Group's incremental borrowing rate. Generally, the Group uses its incremental borrowing rate as the discount rate.

Lease payments included in the measurement of the lease liability comprise the following:

－ fixed payments, including in-substance fixed payments;
－ variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;
－ amounts expected to be payable under a residual value guarantee; and
－ payments for purchase or termination options that are reasonably certain to be exercised.

(Continued)

~ 172 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES

Notes to the Consolidated Financial Statements

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when:

－
there is a change in future lease payments arising from the change in an index or rate; or
－ there is a change in the Group's estimate of the amount expected to be payable under a residual value guarantee; or
－ there is a change in the lease term resulting from a change of its assessment on whether it will exercise an option to purchase the underlying asset, or
－ there is a change of its assessment on whether it will exercise a purchase, extension or termination option; or
－
there is any lease modifications

When the lease liability is remeasured, other than lease modifications, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or in profit and loss if the carrying amount of the right-of-use asset has been reduced to zero.

When the lease liability is remeasured to reflect the partial or full termination of the lease for lease modifications that decrease the scope of the lease, the Group accounts for the remeasurement of the lease liability by decreasing the carrying amount of the right-of-use asset to reflect the partial or full termination of the lease, and recognize in profit or loss any gain or loss relating to the partial or full termination of the lease.

The Group presents right-of-use assets that do not meet the definition of investment and lease liabilities as a separate line item respectively in the statement of financial position.

The Group has elected not to recognize right-of-use assets and lease liabilities for short-term leases of office equipment that have a lease term of 12 months or less and leases of low-value assets, including IT equipment. The Group recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.

(l) Intangible assets
(i) Recognition and measurement

Other intangible assets, including computer software, that are acquired by the Group and have finite useful lives are measured at cost less accumulated amortization and any accumulated impairment losses.

(ii) Subsequent expenditure

Subsequent expenditure is capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditure, including expenditure on internally generated goodwill and brands, is recognized in profit or loss as incurred.

(Continued)

~ 173 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

(iii) Amortization

Amortization is calculated over the cost of the asset, less its residual value, and is recognized in profit or loss on a straight-line basis over the estimated useful lives of intangible assets, other than goodwill, from the date that they are available for use.

The estimated useful lives for current and comparative periods are as follows:

Computer software 3~10 years

Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

(m) Impairment of non-financial assets

At each reporting date, the Group reviews the carrying amounts of its non-financial assets (other than inventories, contract assets, deferred tax assets and assets arising from employee benefits) to determine whether there is any indication of impairment. If any such indication exists, then the asset's recoverable amount is estimated. Goodwill is tested annually for impairment.

For impairment testing, assets are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or CGUs. Goodwill arising from a business combination is allocated to CGUs or groups of CGUs that are expected to benefit from the synergies of the combination.

The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. Value in use is based on the estimated future cash flows, discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU.

An impairment loss is recognized if the carrying amount of an asset or CGU exceeds its recoverable amount.

Impairment losses are recognized in profit or loss. They are allocated first to reduce the carrying amount of any goodwill allocated to the CGU, and then to reduce the carrying amounts of the other assets in the CGU on a pro rata basis.

An impairment loss in respect of goodwill is not reversed. For other assets, an impairment loss is reversed only to the extent that the asset's carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

(n) Provisions

A provision is recognized if, as a result of a past event, the Group has a present obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects the current market assessments of the monetary market time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

The Group shall provide one-thousandth of the total contract amounts for the completed project within one year of the period-end settlement for the project warranty reserve. When the actual expenditure occurs, the provision is reversed, and if there is a deficiency, it is listed as the annual expense.

A provision for onerous contracts is recognized when the expected benefits to be derived by the Group from a contract are lower than the unavoidable cost of meeting its obligations under the contract. The provision is measured at the present value of the lower of the expected cost of terminating the contract and the expected net cost of continuing with the contract. Before a provision is established, the Group recognizes any impairment loss on the assets associated with that contract.

(o) Revenue Recognition

Revenue is measured based on the consideration to which the Group expects to be entitled in exchange for transferring goods or services to a customer. The Group recognizes revenue when it satisfies a performance obligation by transferring control of a good or a service to a customer. The accounting policies for the Group's main types of revenue are explained below.

(i) Sale of goods

The Group recognizes revenue when control of the products has transferred, being when the products are delivered to the customer, the customer has full discretion over the channel and price to sell the products, and there is no unfulfilled obligation that could affect the customer's acceptance of the products. Delivery occurs when the products have been shipped to the specific location, the risks of obsolescence and loss have been transferred to the customer, and either the customer has accepted the products in accordance with the sales contract, the acceptance provisions have lapsed, or the Group has objective evidence that all criteria for acceptance have been satisfied.

A receivable is recognized when the goods are delivered as this is the point in time that the Group has a right to an amount of consideration that is unconditional.

(ii) Consulting Services

The Group is engaged in providing construction consulting and design services. Revenue from providing services is recognized in the accounting period in which the services are rendered. For fixed price contracts, revenue is recognized based on the actual service provided to the end of the reporting period as a proportion of the total services to be provided. The proportion of services provided is determined based on the surveys of work performed.

Notes to the Consolidated Financial Statements

(iii) Construction contracts

The Group enters into contracts to design and install constructions. Because its customer controls the asset as it is being constructed, the Group recognizes revenue over time basis of the construction costs incurred to date as a proportion of the total estimated costs of the contract. The consideration promised in the contract includes fixed and variable amounts. Considering the progress of a public construction is highly susceptible to factors outside the Group's control and, therefore, completion bonus is usually constrained, the Group recognizes revenue only to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. If the Group has recognized revenue, but not issued a bill, then the entitlement to consideration is recognized as a contract asset. The contract asset is transferred to receivables when the entitlement to payment becomes unconditional.

If the Group cannot reasonably measure its progress towards complete satisfaction of the performance obligation of a construction contract, the Group shall recognize revenue only to the extent of the costs expected to be recovered.

A provision for onerous contracts is recognized when the Group expects the unavoidable costs of performing the obligations under a construction contract exceed the economic benefits expected to be received under the contract.

Estimates of revenues, costs or extent of progress toward completion are revised if circumstances change. Any resulting increases or decreases in estimated revenues or costs are reflected in profit or loss in the period in which the circumstances that give rise to the revision become known by management.

For constructions, the Group offers a standard warranty to provide assurance that they comply with agreed-upon specifications and has recognized warranty provisions for this obligation.

(p) Contract costs
(i) Incremental costs of obtaining a contract

The Group recognizes as an asset the incremental costs of obtaining a contract with a customer if the Group expects to recover those costs. The incremental costs of obtaining a contract are those costs that the Group incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained. Costs to obtain a contract that would have been incurred regardless of whether the contract was obtained shall be recognized as an expense when incurred, unless those costs are explicitly chargeable to the customer regardless of whether the contract is obtained.

The Group applies the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less.

Notes to the Consolidated Financial Statements

(ii) Costs to fulfil a contract

If the costs incurred in fulfilling a contract with a customer are not within the scope of another Standard (for example, IAS 2 Inventories, IAS 16 Property, Plant and Equipment or IAS 38 Intangible Assets), the Group recognizes an asset from the costs incurred to fulfil a contract only if those costs meet all of the following criteria:

‧The costs relate directly to a contract or to an anticipated contract that the Group can specifically identify;
‧The costs generate or enhance resources of the Group that will be used in satisfying (or in continuing to satisfy) performance obligations in the future; and
‧The costs are expected to be recovered.

General and administrative costs, costs of wasted materials, labor or other resources to fulfil the contract that were not reflected in the price of the contract, costs that relate to satisfied performance obligations (or partially satisfied performance obligations), and costs for which the Group cannot distinguish whether the costs relate to unsatisfied performance obligations or to satisfied performance obligations(or partially satisfied performance obligations), the Group recognizes these costs as expenses when incurred.

(q) Employee benefits

(i) Defined contribution plans

Obligations for contributions to defined contribution plans are expensed as the related service is provided.

(ii) Defined benefit plans

The Group's net obligation in respect of defined benefit plans is calculated separately for each the plan by estimating the amount of future benefit that employees have earned in the current and prior periods, discounting that amount and deducting the fair value of any plan assets.

The calculation of defined benefit obligations is performed annually by a qualified actuary using the projected unit credit method. When the calculation results in a potential asset for the Group, the recognized asset is limited to the present value of economic benefits available in the form of any future refunds from the plan or reductions in future contributions to the plan. To calculate the present value of economic benefits, consideration is given to any applicable minimum funding requirements.

Remeasurements of the net defined benefit liability, which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income, and accumulated in retained earnings within equity. The Group determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the then-net defined benefit liability (asset). Net interest expense and other expenses related to defined benefit plans are recognized in profit or loss.

(Continued)

~ 177 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES

Notes to the Consolidated Financial Statements

When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. The Group recognizes gains and losses on the settlement of a defined benefit plan when the settlement occurs.

(iii) Short term employee benefits

Short-term employee benefits are expensed as the related service is provided. A liability is recognized for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably.

(r) Income tax

Income taxes comprise current taxes and deferred taxes. Except for expenses related to business combinations or recognized directly in equity or other comprehensive income, all current and deferred taxes are recognized in profit or loss.

Current taxes comprise the expected tax payables or receivables on the taxable profits (losses) for the year and any adjustment to the tax payable or receivable in respect of previous years. The amount of current tax payables or receivables are the best estimate of the tax amount expected to be paid or received that reflects uncertainty related to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date.

Deferred taxes arise due to temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases. Deferred taxes are recognized except for the following:

(i) temporary differences on the initial recognition of assets and liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profits (losses) at the time of the transaction;
(ii) temporary differences related to investments in subsidiaries, associates and joint arrangements to the extent that the Group is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and
(iii) taxable temporary differences arising on the initial recognition of goodwill.

Deferred taxes are measured at tax rates that are expected to be applied to temporary differences when they reserve, using tax rates enacted or substantively enacted at the reporting date.

(Continued)

~ 178 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES

Notes to the Consolidated Financial Statements

Deferred tax assets and liabilities are offset if the following criteria are met:

(i) the Group has a legally enforceable right to set off current tax assets against current tax liabilities; and
(ii) the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either:
1) the same taxable entity; or
2) different taxable entities which intend to settle current tax assets and liabilities on a net basis, or to realize the assets and liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered.

Deferred tax assets are recognized for the carry forward of unused tax losses, unused tax credits, and deductible temporary differences to the extent that it is probable that future taxable profits will be available against which they can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefits will be realized; such reductions are reversed when the probability of future taxable profits improves.

(s) Earnings per share

The Group discloses the Company's basic and diluted earnings per share attributable to ordinary shareholders of the Company. Basic earnings per share is calculated as the profit attributable to ordinary shareholders of the Company divided by the weighted average number of ordinary shares outstanding. Diluted earnings per share is calculated as the profit attributable to ordinary shareholders of the Company divided by the weighted average number of ordinary shares outstanding after adjustment for the effects of all potentially dilutive ordinary shares.

(t) Operating segments

An operating segment is a component of the Group that engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of the Group). Operating results of the operating segment are regularly reviewed by the Group's chief operating decision maker to make decisions about resources to be allocated to the segment and to assess its performance. Each operating segment consists of standalone financial information.

(5) Significant accounting assumptions and judgments, and major sources of estimation uncertainty

The preparation of the consolidated financial statements in conformity with the Regulations and the IFRSs endorsed by the FSC requires management to make judgments, estimates, and assumptions that affect the application of the accounting policies and the reported amount of assets, liabilities, income, and expenses. Actual results may differ from these estimates.

(Continued)

~ 179 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

Information about judgments made in applying accounting policies that have the most significant effects on the amounts recognized in the consolidated financial statements is as follows:

(a) Judgment regarding significant influence of investees

The Group has less than 20% of the voting or potential voting rights of Wholetech System Hitech Limited, JG Environmental Technology Co., Ltd. and Eco Energy Corporation. However, the Group has determined that it has significant influence because it has representation on the board of Wholetech System Hitech Limited, JG Environmental Technology Co., Ltd. and Eco Energy Corporation.

(b) Judgment of whether the Group has substantive control over its investees

The Group holds 33.30% of the outstanding voting shares of Ablerex Electronics Co., Ltd and is the single largest shareholder of the investee. Although the remaining 66.70% of Ablerex Electronics Co., Ltd's shares are not concentrated within specific shareholders, the Group still cannot obtain more than half of the total number of Ablerex Electronics Co., Ltd's directors. Therefore, it is determined that the Group has significant influence on Ablerex Electronics Co., Ltd.

Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next financial year is as follows:

(a) Impairment assessment of accounts receivable

The Group has estimated the allowance for loss on trade receivable that is based on the risk of default occurring and the rate of expected credit loss. The Group has considered historical experience, current economic conditions and forward-looking information at the reporting date to determine the assumptions to be used in calculating impairments and the selected inputs. For relevant assumptions and input values, please refer to Note 6 (c).

(b) Revenue recognition

The Group recognizes contract revenues based on the degree of completion on construction contracts; degree of completion is calculated with contract costs incurred to date as a percentage of estimated total contract costs. The Group considers the nature of each project, the estimated construction period, the project item, the construction process, the construction method and the estimated amount of the subcontracts when estimating total contract costs. Any changes in the estimates above may result in a significant adjustment to the estimated amount, please refer to Note 6 (u).

(c) Fair value of financial instruments

The fair value of financial instruments in non active markets or without open market quotes is determined by evaluation models or counterparty quotations. When using the evaluation model to determine fair value, all models only use observable data as input values without artificial adjustment. The observable input value is based on the principle of long term stable market used parameters to avoid differences in cross period financial reporting due to changes in data sources. The model must be repeatedly adjusted and verified to ensure that the output is sufficient to properly reflect the value of the asset.

For detailed information on the main assumptions used in determining the fair value of the financial instruments and detailed sensitivity analysis of these assumptions, please refer to Note 6 (x).

(d) Measurement of defined benefit obligations

Defined benefit costs and net defined benefit liabilities (assets) under defined benefit pension plans are calculated using the Projected Unit Credit Method. The appropriate actuarial assumptions include the discount rate, employee turnover rate, and future salary increase rate. Changes in economic circumstances and market conditions will affect these assumptions and may have a material impact on the amount of the expense and liability. Please refer to Note 6 (q) for the material actuarial assumptions and sensitivity analysis for actuarial calculations.

Discount rate Future salary increases rate	December 31, 2020 0.35% 2.00%	December 31, 2019 1.10% 1.50%

The expected allocation payment to be made by the Group to the defined benefit plans for the one-year period after the reporting date is $2,974 thousand.

The weighted average lifetime of the defined benefit plans is 8.48 years.

7) Sensitivity analysis

As of December 31, 2020 and 2019, if the actuarial assumptions had changed, the impact on the present value of the defined benefit obligations shall be as follows:

December 31, 2020 Discount rate (0.50%) Future salary increase rate (0.25%) December 31, 2019 Discount rate (0.50%) Future salary increase rate (0.25%)	The impact of defined benefit obligations Increase Decrease $ (17,757) 13,217 9,006 (8,779) (16,723) 17,853 8,531 (8,301)
	Increase $ (17,757) 9,006 (16,723) 8,531

Reasonably possible changes at the reporting date to one of the relevant actuarial assumptions, holding other assumptions constant, would have affected the defined benefit obligation by the amounts shown above. The method used in the sensitivity analysis is consistent with the calculation of pension liabilities in the balance sheets.

There is no change in the method and assumptions used in the preparation of sensitivity analysis for 2020 and 2019.

(v) Employee compensation and directors' remuneration

In accordance with the articles of incorporation the Company should contribute 6% to 10% of the profit as employee compensation and less than 2% as directors' remuneration when there is profit for the year.

Notes to the Consolidated Financial Statements

The Group does not expect the cash flows included in the maturity analysis to occur significantly earlier or at significantly different amounts.

(iii) Currency risk
1) Exposure to foreign currency risk

The Group's significant exposure to foreign currency risk were as follows:

December 31, 2020	December 31, 2020	December 31, 2020	December 31, 2019 Foreign currency Exchange rate (dollars) TWD 82,127 29.98 2,462,167 290,420 4.31 1,250,258 65 22.28 1,448 476,604 4.31 2,051,779 14,922 29.98 447,362 486 33.59 16,325 416 0.28 115 3,365 4.31 14,486 339 22.28 7,553	December 31, 2019 Foreign currency Exchange rate (dollars) TWD 82,127 29.98 2,462,167 290,420 4.31 1,250,258 65 22.28 1,448 476,604 4.31 2,051,779 14,922 29.98 447,362 486 33.59 16,325 416 0.28 115 3,365 4.31 14,486 339 22.28 7,553

2) Sensitivity analysis

The Group's exposure to foreign currency risk arises from the translation of the foreign currency exchange gains and losses on cash and cash equivalents, accounts receivable, other receivables, financial assets at fair value through other comprehensive income, accounts payable and other payables that are denominated in foreign currency. A (weakening) strengthening of 1% of the NTD against the USD, EUR, CNY, SGD and JPY, the Group's net income before tax would have increased (decreased) by $22,624 thousand and $25,824 thousand, and other comprehensive income would have increased (decreased) by $15,670 thousand and $16,414 thousand, for the years ended December 31, 2020 and 2019, respectively. The analysis was performed on the same basis for both periods.

3) Foreign exchange gain and loss on monetary items

Since the Group has many kinds of functional currency, the information on foreign exchange gain (loss) on monetary items is disclosed by total amount. For the years ended December 31, 2020 and 2019, foreign exchange loss (including realized and unrealized portions) amounted to $62,965 thousand and $108,563 thousand, respectively.

Notes to the Consolidated Financial Statements

(iv) Interest rate analysis

Please refer to the notes on liquidity risk management and interest rate exposure of the Group's financial assets and liabilities.

If the interest rate had increased/decreased by 0.25%, the Group's net income would have increased/decreased by $24,005 thousand and $21,685 thousand for the years ended December 31, 2020 and 2019, respectively, with all other variable factors remaining constant.

(v) Fair value of financial instruments
1) Fair value hierarchy

To provide disclosure information, the Group classifies the measurement of fair value based on fair value hierarchy which reflects the significance of the inputs during the measurement. The Group categorizes fair value into the following levels:

a) Level 1

Level 1 inputs are quoted prices in active markets for identical financial instruments. An active market is a market in which all the following conditions exist:

i) The items traded within the market are homogeneous.
ii) Willing buyers and sellers can normally be found at any time.
iii) Prices are available to the public.
b) Level 2

Level 2 inputs are inputs other than quoted market prices included within Level 1 that are observable for the asset or liability, either directly (i.e., prices) or indirectly (i.e. derived from prices).

c) Level 3

Level 3 inputs are valuation parameters which are not based on the information available in the market or the quoted price from the counter party. For example, historical volatility used in option pricing models is an unobservable input since it cannot represents the expected value of future volatility of the entire market participants.

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES

Notes to the Consolidated Financial Statements

The fair value of financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income is measured on a recurring basis. The carrying amount and fair value of the Group's financial assets and liabilities, including the information on fair value hierarchy were as follows; however, for financial instruments not measured at fair value whose carrying amount is reasonably close to the fair value, disclosure of fair value information is not required:

	December 31, 2020	December 31, 2020	December 31, 2020	Total 506,695

$ 2,272,305	34,346	179,833	2,058,126	2,272,305

2) Transfer between Level 1 and Level 2

There were no transfers from Level 1 to Level 2 for the years ended December 31, 2020 and 2019.

$ 6,347 2,051,779		2,058,126

Total gains and losses were recognized in "other gains and losses" and "unrealized gains and losses from financial assets at fair value through other comprehensive income".

4) Quantified information on significant unobservable inputs (Level 3) used in fair value measurement

The Group's financial instruments that use Level 3 inputs to measure fair value include － "financial assets measured at fair value through profit or loss equity investments" and "financial assets measured at fair value through other comprehensive income - equity investments".

The equity investments which are lack of active market and categorized into Level 3 have numerous significant unobservable inputs. The significant unobservable inputs of equity investments without active market are independent between each other. Hence, there is no correlation between each significant unobservable input.

6) Financial instruments not measured at fair value

a) Fair value information

The Group's financial instruments not measured at fair value include cash and cash equivalents, notes and accounts receivable, other receivables, guarantee deposits paid, notes and accounts payable, other payables, guarantee deposits received and part of other financial assets, whose carrying amount is reasonably close to the fair value, disclosure of fair value information is not required.

b) Valuation techniques

The Group's valuation methods and assumptions used for financial instruments not measured at fair value are as follows:

Since the maturity date is close and the future receipt and reimbursement price is similar to the book value, the fair value of cash and cash equivalents, notes and accounts receivable, other receivables, notes and accounts payable and other payables were measured at book value at the reporting date.

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

(y) Financial risk management
(i) Overview

The Group has exposures to the following risks arising from its financial instruments:

1) Credit risk
2) Liquidity risk
3) Market risk

The following likewise discusses the Group's objectives, policies and processes for measuring and managing the above mentioned risks.

(ii) Structure of risk management

The Group's risk management policies are established to identify and analyze the risks faced by the Group, to set appropriate risk limits and controls, and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Group's activities. The Group, through its training and management standards and procedures, aims to develop a disciplined and constructive control environment in which all employees understand their roles and obligations.

(iii) Credit risk
1) Notes and accounts receivable

Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Group is required to conduct management and credit risk analysis for each of its new customers before the terms and conditions of the contract and delivery are set in accordance with the internal credit policy. The internal risk control system assesses the credit quality of customers by considering their financial status, past experiences and other factors. The main credit risk derives from cash and cash equivalents, deposits in banks and in financial institutions. Furthermore, credit risk may derive from customers, including unreceived receivables and committed transaction.

2) Guarantees

The Group's policy is to provide financial guarantees only to wholly owned subsidiaries. As of December 31, 2020 and 2019, no other guarantees were outstanding.

(iv) Liquidity risk

Liquidity risk is the risk that the Group will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset.

(Continued)

~ 210 ~

UNITED INTEGRATED SERVICES CO., LTD. AND SUBSIDIARIES Notes to the Consolidated Financial Statements

The Group manages sufficient cash and cash equivalents so as to cope with its operations and mitigate the effects of fluctuations in cash flows. The Group's management supervises the banking facilities and ensures compliance with the terms of loan agreements.

As of December 31, 2020 and 2019, the Group's unused credit line were amounted to $7,683,833 thousand and $2,669,748 thousand, respectively.

(v) Market risk

Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates, and equity prices, will affect the Group's income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, and optimizing the return.

1) Currency risk

The Group is a multinational institution and therefore exposes to currency risk deriving from many different currencies, mainly from USD and RMB. The relevant currency risk stems from future commercial transactions, recognized assets and liabilities, and net investments in foreign operating agencies.

2) Interest rate risk

The short-term loans of the Group are debts with floating interest rates. Therefore, changes in market interest rates will lead to changes in the interest rate of short-term loans, resulting in fluctuations of future cash flows.

3) Other market price risk

The Group is exposed to equity price risk due to the investments in equity securities. This is a strategic investment and is not held for trading. The Group does not actively trade in these investments as the management of the Group minimizes the risk by holding different investment portfolios.

(z) Capital management

The Group's objectives for managing capital to safeguard the capacity to continue to operate, to continue to provide a return on shareholders, to maintain the interest of other related parties, and to maintain an optimal capital structure to reduce the cost of capital.

(b) Certain directors of the Company were sentenced of violating the Securities and Exchange Act by the Taiwan High Court (the “High Court”). With respect to the main content of the judgment, corresponding measures and the impact of the litigation on the operations, please refer to the following information:
(i) Main Content of the Judgment

On June 5, 2013, the Taipei District Prosecutors Office (the “Prosecutors Office”) filed a public prosecution against Chairman Chen and former Chairman Wang of the Company, and others, on the accusation of embezzlement, and claimed that between 2001 and 2011, the defendants have transferred more than NT$1.3 billion, from the funds of Company, to other companies that are effectively controlled by the defendants as follows: Dentsu Engineering Co. Ltd (“Dentsu”), Fukuo Engineering Co. Ltd., and Huayuan Engineering Co. Ltd. After the defendants presented numerous evidence to clarify the relevant facts during the trial, the Taipei District Court sentenced on August 31, 2015 (No. 102 Jin-Chung-Chung-Su-Tzu 17) with the following main content: the court adopts the defendants' explanations and evidence regarding the NT$1.3 billion, as mentioned in the indictment, that the funds, except for part of them are payment for construction fee and the wages of the construction workers, the rest of the funds were used for repaying several incidental payments (collectively referred to as the “Package Fees”), previously paid by Dentsu and other companies. There is also no evidence provided that the defendants had committed an offence involving embezzlement or breach of trust; therefore, the court considers that the defendants were not guilty of each of the above-mentioned criminal charge. However, the court still held the defendants guilty for financial statement fraud due to failure to disclose in the financial statements of Dentsu and other companies and the Package Fees thereof. The defendants all appealed against the conviction while the public prosecutor also filed an appeal against the acquittal part of the verdict; and due to the death of Mr. Wang, the former Chairman of the Company, the High Court (No. 104 Jin-Shang-Chung-Su-Tzu 40) declared a dismissal judgment for Mr. Wang on July 25, 2017 with respect to the charges of non-arm's length transactions, breach of trust, and embezzlement. The High Court stated that there was no evidence to prove that the defendants, other than Mr. Wang, were guilty and the public prosecutor accepted the acquittal judgment without further appeal. As for the High Court's decision of guilty on the financial statement fraud, the sentences on two of the defendants were finalized because they were given probations and decided not to appeal; while Chairman Chen appealed to the Supreme Court, wherein the Supreme Court (No. 106 Tai-Shang-Tzu 3336), on July 25, 2018, reversed and remanded the case to the High Court whose further judgment (No. 107 Jin-Shang-Chung-Geng-Yi-Tzu 8) on December 10, 2019 sentenced Mr. Chen guilty for misrepresented financial statements for certain years and guilty for violations of the Business Entity Accounting Act, as well as a five-year probation; Chairman Chen filed an appeal while the SFIPC center also requested the prosecutor to appeal. The Supreme Court reversed and remanded the case to the High Court on July 17, 2020, moving the case for further proceedings in the High Court.

(ii) Corresponding Measures

Since the establishment of the Company by the former Chairman Wang, the performance and earnings have always surpassed those of the same industry. Apart from having no deficit, almost all distributable surplus has always been distributed to shareholders; additionally, Chairman Wang almost has never sold his shares in the Company since the Company was listed on the OTC market, which proves Chairman Wang's loyalty and confidence in the Company; Chairman Chen has assisted with matters of the Company for decades and has worked hard for the Company. Owing to the contributions of both of them, the Company has thrived and has been able to consistently make stable profits. Therefore, we feel grateful that the investigation by the first and second instance courts and the retrial court resulting in the opinions of the court that the assertions of non-arm's length transactions, breach of trust and embezzlement as indicted by the prosecutor are not true. It is regrettable that the court still considers that the financial reports of certain fiscal years are misrepresented. As the Supreme Court has reversed and remanded the case to the High Court, the Company will await the final judgment.

(iii) Impact on the Operations

(iv) On December 5, 2013, based on the contents of the indictment, the SFIPC argued that it was inappropriate for the former three directors to hold such positions in the Company and appealed for court decision to dismiss the directors' positions.

As mentioned above, under the leadership of the former Chairman Wang, the operations and performances of the Company were extremely good. Apart from the record of the indictment, the SFIPC did not propose any specific evidence of the three directors' unsuitability for directorship. On February 6, 2014, the shareholders' meeting was held, and after discussion and resolutions, the majority of shareholders supported the decision for the three directors to continue to run the Company. In 2015, the shareholders' general meeting re-elected directors, and the three directors also won the majority of the shareholders' support for re-election. Under the Taipei District Court's ruling in June 18, 2015, the SFIPC lost the lawsuit. The SFIPC filed an appeal, but due to the death of Chairman Wang, the SFIPC withdrew part of the appeal and changed its petition to be dismissing two directors' positions from June 16, 2015 to June 15, 2018. The court of Second Instance decided in early February 2016 to dismiss the complaint of the SFIPC about changes of claims. The SFIPC appealed to the Court of Third Instance on March 28, 2016. The Supreme Court (No. 106 Tai-Shang-Tzu 2658) revoked the original Second Instance judgment on September 28, 2018, and remanded the case to the High Court. On April 28, 2020, the two directors were disqualified from being a director by the High Court order. Both directors filed appeals on May 18, 2020, but due to the resignation of director Lee on June 2, 2020, she withdrew the appeal on June 3 in the same year and the court's decision on director Lee became finalized as of the date thereof; while the appeal part regarding director Chen is currently under the trial of the Supreme Court. The financial and business operations of the Company have also not been affected by this lawsuit.

Notes to the Consolidated Financial Statements

(v) According to the content of the indictment on January 27, 2014, the SFIPC filed a group lawsuit on behalf of the investor on the grounds that the Company's financial reports from the third quarter of 2008 to 2011 were misrepresented, requesting the Company, directors and former supervisors to jointly compensate the investors for the damage amounting to more than NT$243 million.
- As stated above, the Company's operations and financial position have always been sound, and its share price has remained at a considerable level. It has been a stable and profitable Company for a long time. Relevant parties have also indicated that the Company has handled the affairs of the Company's interests and has not caused the Company's financial reports to be misrepresented. The judgment of the criminal first retrial court also holds that even though the Company's financial reports and financial business documents between years 2008 and 2011 were indeed misrepresented and have not reached materiality criteria, they have only violating the Business Accounting Laws regulations. As the Supreme Court reversed and remanded the case to the High Court, the case remains for further proceedings in the High Court. Before the criminal case and the final judgment of this civil action are determined, whether the Company has misrepresented financial reports in the past years stated, the investors have been harmed, or the damage is related to false financial reporting, etc., it would take a period of time before the judgment is announced. This lawsuit has also not affected the normal operation of the Company's current financial business.
(c) The Company received the civil judgment from the Taiwan Taipei District Court on September 2, 2014 that the Company should pay the package fees of $104,559 thousand and the former Chairman Wang's salary from January 2001 to April 2012, as previously paid by Dentsu, amounting to $21,405 thousand.

As of the reporting date, the Company has yet to reimburse the abovementioned package fees, salary and related interests.

(d) On September 5, 2016, Jiangxi United Integrated Services Ltd. (“Jiangxi UIS”) and Fujian Mantix Display Technology Co. Ltd. (“Fujian Mantix”) have executed the “Clean City Subcontract A Turn-Key Agreement” for the “Phrase I Project of the Fujian Mantix High-Tech Panel Construction” (“Project”) in Hanjiang District, Putian City, and have subsequently executed four supplemental agreements, including the “Electrical and Mechanical Installation Project of Section A” and the “Light Current System Installation Project”. Jiangxi UIS had performed all of the obligations arising from the abovementioned agreements; while Fujian Mantix accepted and put the Project into operation for which warranty coverage has expired but failed to make payments amounting to CNY 27,303 thousand pursuant to the Agreements. On April 23, 2020, Jiangxi UIS filed a lawsuit to recover the unpaid fees and relevant interest and applied for an asset preservation order in the Fujian Putian Middle Class People's Court (“People's Court”). On June 5, 2020, the People's Court ordered to freeze Fujian Mantix's certain bank accounts within a certain range of deposit amounts. A meditated settlement agreement (“Settlement”) was reached between the parties subsequently and was approved by the People's Court on September 28, 2020. Pursuant to the Settlement, the parties agreed that the total sum of the unpaid amount shall be CNY 28,000 thousand (“Settlement Amount”). The Settlement Amount shall be paid in 7 installments commencing on October 31, 2020 with the last payments due on April 30, 2021, and if Fujian Mantix fails to pay on time, the total sum of the payment will be restored back to amount recognized by the parties amounting to CNY 27,301 thousand plus the interest of CNY 1,200 thousand.

Appendix B

Independent Auditors' Report

To the Board of Directors of United Integrated Services Co., Ltd.:

Opinion

We have audited the financial statements of United Integrated Services Co., Ltd. ("the Company"), which comprise the balance sheets as of December 31, 2020 and 2019, the statements of comprehensive income, changes in equity and cash flows for the years then ended, and notes to the financial statements, including a summary of significant accounting policies.

In our opinion, based on our audits and the reports of other auditors (please refer to Other Matter section), the accompanying financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and its financial performance and its cash flows for the years then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers.

Basis for Opinion

We conducted our audits in accordance with the Regulations Governing Auditing and Certification of Financial Statements by Certified Public Accountants and the auditing standards generally accepted in the Republic of China. Our responsibilities under those standards are further described in the Auditors' Responsibilities for the Audit of the Financial Statements section of our report. We are independent of the Company in accordance with the Certified Public Accountants Code of Professional Ethics in Republic of China ("the Code"), and we have fulfilled our other ethical responsibilities in accordance with the Code. Based on our audits and the reports of other auditors, we believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis of our opinion.

Emphasis of Matter

Some board members of United Integrated Services Co., Ltd. were sentenced of violating the Securities Exchange Act by the Taiwan High Court. For circumstances of these cases, please refer to Note12 (b) of the financial statements. Our opinion is not modified in respect of this matter.

~ 232 ~

Other Matter

We did not audit the financial statements of certain investee companies under the equity method and Note 13 (b) "Information on investees of the financial statements". Those statements were audited by other auditors, whose reports have been furnished to us, and our opinion, insofar as it relates to the amounts included for these investee companies, is based solely on the reports of other auditors. The investments in the investee companies constituted 3.54% and 4.22% of the total assets, as of December 31, 2020 and 2019, respectively. For the years then ended, the recognized shares of profit of associates accounted for using the equity method of these investee companies constituted 1.04% and 1.34% of the total profit before tax, respectively.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current period. These matters were addressed in the context of our audit of the financial statements as a whole and in forming our opinion thereon, and we do not provide a separate opinion on these matters. In our judgment, the key audit matters we communicated in the auditors' report were as follows:

1. Revenue recognition

For the accounting policies related to revenue recognition, please refer to Note 4 (o) "Revenue recognition"; for uncertainty of accounting estimates and assumption for revenue recognition, please refer to Note 5 (b) "Revenue recognition"; for information of revenue recognition, please refer to Note 6 (s) "Revenue from contracts with customers" to the financial statements.

Description of Key Audit Matter:

The Company recognizes construction contract revenue by percentage of completion method. The percentage of completion is based on the contract costs incurred as of the financial statements reporting date, representing the percentage of the estimated total contract costs. Because construction contract accounting involves a high level of estimation and judgment, revenue recognition has been identified as one of the key audit matters for our audit.

How the matter was addressed in our audit:

In relation to the key audit matter above, our principal audit procedures included testing the effectiveness of the internal control related to the timing and precision of revenue recognition. Through sampling and reviewing new construction contracts and related documents throughout the Company's reporting period, we obtained annual project revenue statistics and validated the correctness of revenue recognized on the projects.

2. Accounts receivable impairment assessment

For the accounting policies related to the impairment assessment of accounts receivable, please refer to Note 4 (f) "Financial instruments"; for uncertainty of accounting estimates and assumption for the impairment assessment of accounts receivable, please refer to Note 5 (a) "Impairment assessment of accounts receivable"; for information of the impairment assessment of accounts receivable, please refer to Note 6 (c) "Notes and accounts receivable" to the financial statements.

Description of Key Audit Matter:

The Company recognized expected credit loss in accordance with the Company's policy of allowance for accounts receivable, and established its estimation based on its clients' credit risk, historical experiences of credit loss, and rational expectation of future economic conditions. Since the accounting of expected credit loss of accounts receivable involves a high level of estimation and judgment, the impairment assessment of accounts receivable has been identified as one of the key audit matters for our audit.

~ 233 ~

How the matter was addressed in our audit:

In relation to the key audit matter above, our principal audit procedures included: (i) understanding the accounting policies of the impairment assessment of notes and trade receivables; (ii) implementing sampling procedures to examine the accuracy of accounts receivable aging report; (iii) analyzing the changes of the aging of accounts receivable in each period; (iv) examining historical collection records; (v) examining subsequent collection status to evaluate the reasonableness of the Company's recognition of allowance for impairment loss.

3. Financial instruments assessment

For the accounting policies related to the assessment of financial instruments, please refer to Note 4 (f) "Financial Instruments"; for uncertainty of accounting estimates and judgments for fair value of financial instruments, please refer to Note 5 (c) "Fair value of financial instruments"; for information of the fair value of financial instruments, please refer to Note 6 (v) "Fair value hierarchy information" to the financial statements.

Description of Key Audit Matter:

How the matter was addressed in our audit:

Responsibilities of Management and Those Charged with Governance for the Financial Statements

Management is responsible for the preparation and fair presentation of the financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers, and for such internal control as management determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the management is responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Those charged with governance (including the Audit Committee) are responsible for overseeing the Company's financial reporting process.

~ 234 ~

Auditors' Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors' report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the auditing standards generally accepted in the Republic of China will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control.
Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the management.
Conclude on the appropriateness of the management's use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors' report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditors' report. However, future events or conditions may cause the Company to cease to continue as a going concern.
Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
Obtain sufficient and appropriate audit evidence regarding the financial information of the investment in other entities accounted for using the equity method to express an opinion on this financial statements. We are responsible for the direction, supervision and performance of the audit. We remain solely responsible for our audit opinion.

~ 235 ~

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditors' report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partners on the audit resulting in this independent auditors' report are Tzu-Hui, Lee and Jung-Lin, Lee.

Amendments to IFRS 3 “Definition of a Business”
Amendments to IFRS 9, IAS39 and IFRS7 “Interest Rate Benchmark Reform”
Amendments to IAS 1 and IAS 8 “Definition of Material”
Amendments to IFRS 16 “COVID-19-Related Rent Concessions”

(b) The impact of IFRS issued by the FSC but not yet effective

The Company assesses that the adoption of the following new amendments, effective for annual period beginning on January 1, 2021, would not have a significant impact on its financial statements:

Amendments to IFRS 4 “Extension of the Temporary Exemption from Applying IFRS 9”
－
● Amendments to IFRS 9, IAS39, IFRS7, IFRS 4 and IFRS 16 “Interest Rate Benchmark Reform Phase 2”
(c) The impact of IFRS issued by IASB but not yet endorsed by the FSC

The following new and amended standards, which may be relevant to the Company, have been issued by the International Accounting Standards Board (IASB), but have yet to be endorsed by the FSC:

Standards or Interpretations Amendments to IFRS 10 and IAS 28 “Sale or Contribution of Assets Between an Investor and Its Associate or Joint Venture” Amendments to IAS 37 “Onerous Contracts－Cost of Fulfilling a Contract”	Content of amendment The amendments address an acknowledged inconsistency between the requirements in IFRS 10 and those in IAS 28 (2011) in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business (whether it is housed in a subsidiary or not). A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary. The amendments clarify that the ‘costs of fulfilling a contract' comprises the costs that relate directly to the contract as follows: ● the incremental costs – e.g. direct labor and materials; and ● an allocation of other direct costs – e.g. an allocation of the depreciation charge for an item of property, plant and equipment used in fulfilling the contract.	Effective date per IASB
		Effective date to be determined by IASB January 1, 2022

The Company is evaluating the impact of its initial adoption of the abovementioned standards or interpretations on its financial position and financial performance. The results thereof will be disclosed when the Company completes its evaluation.

(4) Summary of significant accounting policies

The significant accounting policies presented in the financial statements are summarized below. Except for those specifically indicated, the following accounting policies were applied consistently throughout the periods presented in the financial statements.

(a) Statement of compliance

These financial statements have been prepared in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers (hereinafter referred to as "the Regulations").

(b) Basis of preparation
(i) Basis of measurement

Except for the following significant accounts, the financial statements have been prepared on a historical cost basis:

1) Financial instruments measured at fair value through profit or loss are measured at fair value;
2) Financial assets measured at fair value through other comprehensive income are measured at fair value;
3) The defined benefit liabilities are measured at fair value of the plan assets less the present value of the defined benefit obligation.
(ii) Functional and presentation currency

The functional currency of each entity is determined based on the primary economic environment in which the entity operates. The financial statements are presented in New Taiwan Dollar (NTD), which is the Company's functional currency. All financial information presented in NTD has been rounded to the nearest thousand.

(Continued)

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

(c) Foreign currencies

(i) Foreign currency transactions

Transactions in foreign currencies are translated into the respective functional currencies of Company entities at the exchange rates at the dates of the transactions. At the end of each subsequent reporting period, monetary items denominated in foreign currencies are translated into the functional currencies using the exchange rate at that date. Non-monetary items denominated in foreign currencies that are measured at fair value are translated into the functional currencies using the exchange rate at the date that the fair value was determined. Non-monetary items denominated in foreign currencies that are measured based on historical cost are translated using the exchange rate at the date of the transaction.

Exchange differences are generally recognized in profit or loss, except for those differences relating to the following, which are recognized in other comprehensive income:

an investment in equity securities designated as at fair value through other comprehensive income;
a financial liability designated as a hedge of the net investment in a foreign operation to the extent that the hedge is effective; or
qualifying cash flow hedges to the extent that the hedges are effective.

(ii) Foreign operations

When a foreign operation is disposed of such that control, significant influence, or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal. When the Company disposes of only part of its interest in a subsidiary that includes a foreign operation while retaining control, the relevant proportion of the cumulative amount is reattributed to non-controlling interests. When the Group disposes of only part of its investment in an associate or joint venture that includes a foreign operation while retaining significant influence or joint control, the relevant proportion of the cumulative amount is reclassified to profit or loss.

Notes to the Financial Statements

(d) Classification of current and non-current assets and liabilities

An asset is classified as current under one of the following criteria, and all other assets are classified as non-current.

(i) It is expected to be realized, or intended to be sold or consumed, in the normal operating cycle;
(ii) It is held primarily for the purpose of trading;
(iii) It is expected to be realized within twelve months after the reporting period; or
(iv) The asset is cash or a cash equivalent (as defined in IAS 7) unless the asset is restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period.

A liability is classified as current under one of the following criteria, and all other liabilities are classified as non-current.

An entity shall classify a liability as current when:

(i) It is expected to be settled in the normal operating cycle;
(ii) It is held primarily for the purpose of trading;
(iii) It is due to be settled within twelve months after the reporting period; or
(iv) The Company does not have an unconditional right to defer settlement of the liability for at least twelve months after the reporting period. Terms of a liability that could, at the option of the counterparty, result in its settlement by issuing equity instruments do not affect its classification.

The Company is mainly engaged in the planning, designation and construction contracting of various projects. Its business cycle is about three to five years. Due to assets and liabilities related to the engineering business, are based on operating cycle as the standard for dividing current or non-current.

(e) Cash and cash equivalents

Notes to the Financial Statements

(f) Financial instruments

(i) Financial assets

1) Financial assets measured at amortized cost

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:

‧ it is held within a business model whose objective is to hold assets to collect contractual cash flows; and
‧ its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

2) Fair value through other comprehensive income (FVOCI )

On initial recognition of an equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in the investment's fair value in other comprehensive income. This election is made on an instrument-by-instrument basis.

Dividend income is recognized in profit or loss on the date on which the Company's right to receive payment is established.

3) Fair value through profit or loss (FVTPL)

All financial assets not classified as amortized cost or FVOCI described as above are measured at FVTPL. On initial recognition, the Company may irrevocably designate a financial asset, which meets the requirements to be measured at amortized cost or at FVOCI, as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

(Continued)

~ 246 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

These assets are subsequently measured at fair value. Net gains and losses, including any interest or dividend income, are recognized in profit or loss.

4) Business model assessment

The Company makes an assessment of the objective of the business model in which a financial asset is held at portfolio level because this best reflects the way the business is managed and information is provided to management. The information considered includes:

‧ how the performance of the portfolio is evaluated and reported to the Company's management;

‧ the risks that affect the performance of the business model (and the financial assets held within that business model) and how those risks are managed;
‧ the frequency, volume and timing of sales of financial assets in prior periods, the reasons for such sales and expectations about future sales activity.

Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales for this purpose, and are consistent with the Company's continuing recognition of the assets.

Financial assets that are held for trading or are managed and whose performance is evaluated on a fair value basis are measured at FVTPL.

Impairment of financial assets

The Company recognizes loss allowances for expected credit losses (ECL) on financial assets measured at amortized cost (including cash and cash equivalents, notes and accounts receivable, other receivable, guarantee deposit paid and other financial assets), debt investments measured at FVOCI, accounts receivable and contract assets.

Loss allowance for trade receivables and contract assets are always measured at an amount equal to lifetime ECL.

Lifetime ECLs are the ECLs that result from all possible default events over the expected life of a financial instrument.

The maximum period considered when estimating ECLs is the maximum contractual period over which the Company is exposed to credit risk.

(Continued)

~ 247 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

When determining whether the credit risk of a financial asset has increased significantly since initial recognition and when estimating ECL, the Company considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes both quantitative and qualitative information and analysis based on the Company's historical experience and informed credit assessment as well as forward-looking information.

The Company considers a financial asset to be in default when the financial asset is more than 12 months past due, or the debtor is unlikely to pay its credit obligations to the Company in full.

ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e the difference between the cash flows due to the Company in accordance with the contract and the cash flows that the Company expects to receive). ECLs are discounted at the effective interest rate of the financial asset.

At each reporting date, the Company assesses whether financial assets carried at amortized cost and debt securities at FVOCI are credit-impaired. A financial asset is ‘credit-impaired' when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Evidence that a financial asset is credit-impaired includes the following observable data:

‧ significant financial difficulty of the borrower or issuer;
‧ a breach of contract such as a default or being more than 12 months past due;
‧ the disappearance of an active market for a security because of financial difficulties.

Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets.

The gross carrying amount of a financial asset is written off when the Company has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof. For corporate customers, the Company individually makes an assessment with respect to the timing and amount of write-off based on whether there is a reasonable expectation of recovery. The Group expects no significant recovery from the amount written off. However, financial assets that are written off could still be subject to enforcement activities in order to comply with the Group's procedures for recovery of amounts due.

6) Derecognition of financial assets

The Company derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which the Company neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset.

(Continued)

~ 248 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

The Company enters into transactions whereby it transfers assets recognized in its statement of balance sheet, but retains either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized.

(ii) Financial liabilities

1) Financial liabilities

2) Derecognition of financial liabilities

The Company derecognizes a financial liability when its contractual obligations are discharged or cancelled, or expire. The Company also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

3) Offsetting of financial assets and liabilities

Financial assets and financial liabilities are offset and the net amount presented in the statement of balance sheet when, and only when, the Company currently has a legally enforceable right to set off the amounts and it intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously.

(g) Inventories

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

(h) Investment in associates

Associates are those entities in which the Company has significant influence, but not control or joint control, over their financial and operating policies.

The consolidated financial statements include the Company's share of the profit or loss and other comprehensive income of those associates, after adjustments to align their accounting policies with those of the Company, from the date on which significant influence commences until the date on which significant influence ceases. The Company recognizes any changes of its proportionate share in the investee within capital surplus, when an associate's equity changes due to reasons other than profit and loss or comprehensive income, which did not result in changes in actual significant influence.

Gains and losses resulting from transactions between the Company and an associate are recognized only to the extent of unrelated Company's interests in the associate.

When the Company's share of losses of an associate equals or exceeds its interests in an associate, it discontinues recognizing its share of further losses. After the recognized interest is reduced to zero, additional losses are provided for, and a liability is recognized, only to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of the associate.

(i) Subsidiaries

The Company accounts the investee companies that it possesses control using the equity. Net income, other comprehensive income, and shareholder's equity in the financial reports of the Company and the net income, other comprehensive income, and shareholder's equity that belongs to the owners of parent in the consolidated financial reports should be the same.

The Company accounts the changes in equity, under the condition that control is still present, as equity transactions between the proprietors.

(j) Property, plant and equipment

(i) Recognition and measurement

Items of property, plant and equipment are measured at cost, which includes capitalized borrowing costs, less accumulated depreciation and any accumulated impairment losses.

If significant parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment.

Any gain or loss on disposal of an item of property, plant and equipment is recognized in profit or loss.

(Continued)

~ 250 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

(ii) Subsequent expenditure

Subsequent expenditure is capitalized only if it is probable that the future economic benefits associated with the expenditure will flow to the Company.

(iii) Depreciation

Land is not depreciated.

The estimated useful lives of property, plant and equipment for current and comparative periods are as follows:

1)	Buildings	3~50 years
2)	Machinery	3~7 years
3)	Plant equipment	3~50 years
4)	Transportation equipment	3~7 years
5)	Office equipment	3~10 years
6)	Leasehold improvements	5 years

Depreciation methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

(k) Leases
(i) Identifying a lease

At inception of a contract, the Company assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether:

1) the contract involves the use of an identified asset – this may be specified explicitly or implicitly, and should be physically distinct or represent substantially all of the capacity of a physically distinct asset. If the supplier has a substantive substitution right, then the asset is not identified; and
2) the customer has the right to obtain substantially all of the economic benefits from use of the asset throughout the period of use; and

(Continued)

~ 251 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

3) the customer has the right to direct the use of the asset throughout the period of use only if either:
- the customer has the right to direct how and for what purpose the asset is used throughout the period of use; or
- the relevant decisions about how and for what purpose the asset is used are predetermined and:
  - － the customer has the right to operate the asset throughout the period of use, without the supplier having the right to change those operating instructions; or
  - － the customer designed the asset in a way that predetermines how and for what purpose it will be used throughout the period of use.
(ii) As a lessee

The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be reliably determined, the Company's incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate.

Lease payments included in the measurement of the lease liability comprise the following:

－ fixed payments, including in-substance fixed payments;
－ variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;
－ amounts expected to be payable under a residual value guarantee; and
－ payments for purchase or termination options that are reasonably certain to be exercised.

(Continued)

~ 252 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when:

－
there is a change in future lease payments arising from the change in an index or rate; or
－ there is a change in the Company's estimate of the amount expected to be payable under a residual value guarantee; or
－ there is a change in the lease term resulting from a change of its assessment on whether it will exercise an option to purchase the underlying asset, or
－ there is a change of its assessment on whether it will exercise a purchase, extension or termination option; or
－
there is any lease modifications

When the lease liability is remeasured to reflect the partial or full termination of the lease for lease modifications that decrease the scope of the lease, the Company accounts for the remeasurement of the lease liability by decreasing the carrying amount of the right-of-use asset to reflect the partial or full termination of the lease, and recognize in profit or loss any gain or loss relating to the partial or full termination of the lease.

The Company presents right-of-use assets that do not meet the definition of investment and lease liabilities as a separate line item respectively in the statement of financial position.

The Company has elected not to recognize right-of-use assets and lease liabilities for short-term leases of office equipment that have a lease term of 12 months or less and leases of low-value assets, including IT equipment. The Company recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.

(l) Intangible assets
(i) Recognition and measurement

Other intangible assets, including computer software, that are acquired by the Company and have finite useful lives are measured at cost less accumulated amortization and any accumulated impairment losses.

(ii) Subsequent expenditure

(Continued)

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

(iii) Amortization

The estimated useful lives for current and comparative periods are as follows:

Computer software 3~10 years

Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

(m) Impairment of non-financial assets

At each reporting date, the Company reviews the carrying amounts of its non-financial assets (other than inventories, contract assets, deferred tax assets and assets arising from employee benefits) to determine whether there is any indication of impairment. If any such indication exists, then the asset's recoverable amount is estimated. Goodwill is tested annually for impairment.

An impairment loss is recognized if the carrying amount of an asset or CGU exceeds its recoverable amount.

(n) Provisions

A provision is recognized if, as a result of a past event, the Company has a present obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects the current market assessments of the monetary market time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

(Continued)

~ 254 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

The Company shall provide one-thousandth of the total contract amounts for the completed project within one year of the period-end settlement for the project warranty reserve. When the actual expenditure occurs, the provision is reversed, and if there is a deficiency, it is listed as the annual expense.

A provision for onerous contracts is recognized when the expected benefits to be derived by the Company from a contract are lower than the unavoidable cost of meeting its obligations under the contract. The provision is measured at the present value of the lower of the expected cost of terminating the contract and the expected net cost of continuing with the contract. Before a provision is established, the Company recognizes any impairment loss on the assets associated with that contract.

(o) Revenue recognition

Revenue is measured based on the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control of a good or a service to a customer. The accounting policies for the Company's main types of revenue are explained below.

(i) Sale of goods

The Company recognizes revenue when control of the products has transferred, being when the products are delivered to the customer, the customer has full discretion over the channel and price to sell the products, and there is no unfulfilled obligation that could affect the customer's acceptance of the products. Delivery occurs when the products have been shipped to the specific location, the risks of obsolescence and loss have been transferred to the customer, and either the customer has accepted the products in accordance with the sales contract, the acceptance provisions have lapsed, or the Company has objective evidence that all criteria for acceptance have been satisfied.

A receivable is recognized when the goods are delivered as this is the point in time that the Company has a right to an amount of consideration that is unconditional.

(ii) Consulting Services

The Company is engaged in providing construction consulting and design services. Revenue from providing services is recognized in the accounting period in which the services are rendered. For fixed price contracts, revenue is recognized based on the actual service provided to the end of the reporting period as a proportion of the total services to be provided. The proportion of services provided is determined based on the surveys of work performed.

(Continued)

~ 255 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

(iii) Construction contracts

The Company enters into contracts to design and install constructions. Because its customer controls the asset as it is being constructed, the Company recognizes revenue over time basis of the construction costs incurred to date as a proportion of the total estimated costs of the contract. The consideration promised in the contract includes fixed and variable amounts. Considering the progress of a public construction is highly susceptible to factors outside the Company's control and, therefore, completion bonus is usually constrained, the Company recognizes revenue only to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. If the Company has recognized revenue, but not issued a bill, then the entitlement to consideration is recognized as a contract asset. The contract asset is transferred to receivables when the entitlement to payment becomes unconditional.

If the Company cannot reasonably measure its progress towards complete satisfaction of the performance obligation of a construction contract, the Company shall recognize revenue only to the extent of the costs expected to be recovered.

A provision for onerous contracts is recognized when the Company expects the unavoidable costs of performing the obligations under a construction contract exceed the economic benefits expected to be received under the contract.

For constructions, the Company offers a standard warranty to provide assurance that they comply with agreed-upon specifications and has recognized warranty provisions for this obligation.

(p) Contract costs
(i) Incremental costs of obtaining a contract

The Company recognizes as an asset the incremental costs of obtaining a contract with a customer if the Company expects to recover those costs. The incremental costs of obtaining a contract are those costs that the Company incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained. Costs to obtain a contract that would have been incurred regardless of whether the contract was obtained shall be recognized as an expense when incurred, unless those costs are explicitly chargeable to the customer regardless of whether the contract is obtained.

The Company applies the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred, if the amortization period of the asset that the entity otherwise would have recognized is one year or less.

(Continued)

~ 256 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

(ii) Costs to fulfil a contract

If the costs incurred in fulfilling a contract with a customer are not within the scope of another Standard (for example, IAS 2 Inventories, IAS 16 Property, Plant and Equipment or IAS 38 Intangible Assets), the Company recognizes an asset from the costs incurred to fulfil a contract only if those costs meet all of the following criteria:

‧ The costs relate directly to a contract or to an anticipated contract that the Company can specifically identify;
‧ The costs generate or enhance resources of the Company that will be used in satisfying (or in continuing to satisfy) performance obligations in the future; and
‧ The costs are expected to be recovered.

General and administrative costs, costs of wasted materials, labor or other resources to fulfil the contract that were not reflected in the price of the contract, costs that relate to satisfied performance obligations (or partially satisfied performance obligations), and costs for which the Company cannot distinguish whether the costs relate to unsatisfied performance obligations or to satisfied performance obligations(or partially satisfied performance obligations), the Company recognizes these costs as expenses when incurred.

(q) Employee benefits

(i) Defined contribution plans

Obligations for contributions to defined contribution plans are expensed as the related service is provided.

(ii) Defined benefit plans

The Company's net obligation in respect of defined benefit plans is calculated separately for each the plan by estimating the amount of future benefit that employees have earned in the current and prior periods, discounting that amount and deducting the fair value of any plan assets.

The calculation of defined benefit obligations is performed annually by a qualified actuary using the projected unit credit method. When the calculation results in a potential asset for the Company, the recognized asset is limited to the present value of economic benefits available in the form of any future refunds from the plan or reductions in future contributions to the plan. To calculate the present value of economic benefits, consideration is given to any applicable minimum funding requirements.

Remeasurements of the net defined benefit liability, which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income, and accumulated in retained earnings within equity. The Company determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the then-net defined benefit liability (asset). Net interest expense and other expenses related to defined benefit plans are recognized in profit or loss.

(Continued)

~ 257 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. The Company recognizes gains and losses on the settlement of a defined benefit plan when the settlement occurs.

(iii) Short term employee benefits

Short-term employee benefits are expensed as the related service is provided. A liability is recognized for the amount expected to be paid if the Company has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably.

(r) Income tax

(i) temporary differences on the initial recognition of assets and liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profits (losses) at the time of the transaction;
(ii) temporary differences related to investments in subsidiaries, associates and joint arrangements to the extent that the Group is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and
(iii) taxable temporary differences arising on the initial recognition of goodwill.

Deferred taxes are measured at tax rates that are expected to be applied to temporary differences when they reserve, using tax rates enacted or substantively enacted at the reporting date.

(Continued)

~ 258 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

Deferred tax assets and liabilities are offset if the following criteria are met:

(i) the Company has a legally enforceable right to set off current tax assets against current tax liabilities; and
(ii) the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either:
1) the same taxable entity; or
2) different taxable entities which intend to settle current tax assets and liabilities on a net basis, or to realize the assets and liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered.

Deferred tax assets are recognized for the carry forward of unused tax losses, unused tax credits, and deductible temporary differences to the extent that it is probable that future taxable profits will be available against which they can be utilized. Deferred tax assets are reviewed at each reporting date, and are reduced to the extent that it is no longer probable that the related tax benefits will be realized; such reductions are reversed when the probability of future taxable profits improves.

(s) Earnings per share

(t) Operating segments

The Company has disclosed segment information in the consolidated financial statements, so it is not necessary to disclose such information in the parent company only financial statements.

(5) Significant accounting assumptions and judgments, and major sources of estimation uncertainty

The preparation of the parent company only financial statements in conformity with the IFRSs endorsed by the FSC requires management to make judgments, estimates, and assumptions that affect the application of the accounting policies and the reported amount of assets, liabilities, income, and expenses. Actual results may differ from these estimates.

Information about judgments made in applying accounting policies that have the most significant effects on the amounts recognized in the parent company only financial statements is as follows:

(a) Judgment of whether the Company has substantive control over its investees, please refer to the consolidated financial statement for the year ended December 31, 2020.

(Continued)

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

(b) Judgment regarding significant influence of investees

The Company has less than 20% of the voting or potential voting rights of Wholetech System Hitech Limited, JG Environmental Technology Co., Ltd. and Eco Energy Corporation. However, the Company has determined that it has significant influence because it has representation on the board of Wholetech System Hitech Limited, JG Environmental Technology Co., Ltd. and Eco Energy Corporation.

Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next financial year is as follows:

(a) Impairment assessment of accounts receivable

The Company has estimated the allowance for loss on trade receivable that is based on the risk of default occurring and the rate of expected credit loss. The Company has considered historical experience, current economic conditions and forward-looking information at the reporting date to determine the assumptions to be used in calculating impairments and the selected inputs. For relevant assumptions and input values, please refer to Note 6 (c).

(b) Revenue recognition

The Company recognizes contract revenues based on the degree of completion on construction contracts; degree of completion is calculated with contract costs incurred to date as a percentage of estimated total contract costs. The Company considers the nature of each project, the estimated construction period, the project item, the construction process, the construction method and the estimated amount of the subcontracts when estimating total contract costs. Any changes in the estimates above may result in a significant adjustment to the estimated amount., please refer to Note 6 (s).

(c) Fair value of financial instruments

The fair value of financial instruments in non-active markets or without open market quotes is determined by evaluation models or counterparty quotations. When using the evaluation model to determine fair value, all models only use observable data as input values without artificial adjustment. The observable input value is based on the principle of long-term stable market-used parameters to avoid differences in cross-period financial reporting due to changes in data sources. The model must be repeatedly adjusted and verified to ensure that the output is sufficient to properly reflect the value of the asset.

For detailed information on the main assumptions used in determining the fair value of the financial instruments and detailed sensitivity analysis of these assumptions, please refer to Note 6 (v).

(d) Measurement of defined benefit obligations

Defined benefit costs and net defined benefit liabilities (assets) under defined benefit pension plans are calculated using the Projected Unit Credit Method. The appropriate actuarial assumptions include the discount rate, employee turnover rate, and future salary increase rate. Changes in economic circumstances and market conditions will affect these assumptions and may have a material impact on the amount of the expense and liability. Please refer to Note6 (o) for the material actuarial assumptions and sensitivity analysis for actuarial calculations.

The Company assesses the financial condition of its customers continuously to reduce the credit risk of accounts receivable and requires its customers to provide guarantees and collateral if it is necessary. The Company monitors and reviews the recoverable amount of the accounts receivable to ensure the uncollectible amount are recognized appropriately as impairment loss. Therefore, the expected credit losses are in the expectation of the Company.

Notes to the Financial Statements

2) Sensitivity analysis

The Company's exposure to foreign currency risk arises from the translation of the foreign currency exchange gains and losses on cash and cash equivalents, accounts receivable, other receivables, financial assets at fair value through other comprehensive income, accounts payable and other payables that are denominated in foreign currency. A (weakening) strengthening of 1% of the NTD against the USD, EUR, CNY, SGD and JPY, the Company's net income before tax would have increased (decreased) by $23,928 thousand and $27,919 thousand, and other comprehensive income would have increased (decreased) by $15,670 thousand and $16,414 thousand, for the years ended December 31, 2020 and 2019, respectively. The analysis was performed on the same basis for both periods.

3) Foreign exchange gain and loss on monetary items

Since the Company has many kinds of functional currency, the information on foreign exchange gain (loss) on monetary items is disclosed by total amount. For the years ended December 31, 2020 and 2019, foreign exchange loss (including realized and unrealized portions) amounted to $63,135 thousand and $106,283 thousand, respectively.

(iv) Interest rate analysis

Please refer to the notes on liquidity risk management and interest rate exposure of the Company's financial assets and liabilities.

If the interest rate had increased/decreased by 0.25%, the Company's net income would have increased/decreased by $20,002 thousand and $17,599 thousand for the years ended December 31, 2020 and 2019, respectively, with all other variable factors remaining constant.

(v) Fair value of financial instruments
1) Fair value hierarchy

To provide disclosure information, the Company classifies the measurement of fair value based on fair value hierarchy which reflects the significance of the inputs during the measurement. The Company categorizes fair value into the following levels:

a) Level 1

Level 1 inputs are quoted prices in active markets for identical financial instruments. An active market is a market in which all the following conditions exist:

i) The items traded within the market are homogeneous.
ii) Willing buyers and sellers can normally be found at any time.
iii) Prices are available to the public.

(Continued)

~ 283 ~

UNITED INTEGRATED SERVICES CO., LTD.

Notes to the Financial Statements

b) Level 2

c) Level 3

Level 3 inputs are valuation parameters which are not based on the information available in the market or the quoted price from the counter party. For example, historical volatility used in option pricing models is an unobservable input since it cannot represent the expected value of future volatility of the entire market participants.

The fair value of financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income is measured on a recurring basis. The carrying amount and fair value of the Company's financial assets and liabilities, including the information on fair value hierarchy were as follows; however, for financial instruments not measured at fair value whose carrying amount is reasonably close to the fair value, disclosure of fair value information is not required:

Financial assets at fair value through profit or loss Designated at fair value through profit or loss Financial assets at fair value through other comprehensive income Unquoted equity instrument measured at fair value Total		December 31, 2020	December 31, 2020	December 31, 2020

The Company has exposures to the following risks from its financial instruments:

1) Credit risk
2) Liquidity risk
3) Market risk

The following likewise discusses the Company's objectives, policies and processes for measuring and managing the above mentioned risks.

(ii) Structure of risk management

Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Company's activities. The Company, through its training and management standards and procedures, aims to develop a disciplined and constructive control environment in which all employees understand their roles and obligations.

(iii) Credit risk
1) Notes and accounts receivable

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Company is required to conduct management and credit risk analysis for each of its new customers before the terms and conditions of the contract and delivery are set in accordance with the internal credit policy. The internal risk control system assesses the credit quality of customers by considering their financial status, past experiences and other factors. The main credit risk derives from cash and cash equivalents, deposits in banks and in financial institutions. Furthermore, credit risk may derive from customers, including unreceived receivables and committed transaction.

Notes to the Financial Statements

(iv) Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset.

The Company manages sufficient cash and cash equivalents so as to cope with its operations and mitigate the effects of fluctuations in cash flows. The Company's management supervises the banking facilities and ensures compliance with the terms of loan agreements.

As of December 31, 2020 and 2019, the Company's unused credit line were amounted to $5,969,555 thousand and $1,058,891 thousand, respectively.

(v) Market risk

Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates, and equity prices, will affect the Company's income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, and optimizing the return.

1) Currency risk

The Company is a multinational institution and therefore exposes to currency risk deriving from many different currencies, mainly from USD and RMB. The relevant currency risk stems from future commercial transactions, recognized assets and liabilities, and net investments in foreign operating agencies.

2) Interest rate risk

The short-term loans of the Company are debts with floating interest rates. Therefore, changes in market interest rates will lead to changes in the interest rate of short-term loans, resulting in fluctuations of future cash flows.

3) Other market price risk

The Company is exposed to equity price risk due to the investments in equity securities. This is a strategic investment and is not held for trading. The Company does not actively trade in these investments as the management of the Company minimizes the risk by holding different investment portfolios.

(x) Capital management

The Company's objectives for managing capital to safeguard the capacity to continue to operate, to continue to provide a return on shareholders, to maintain the interest of other related parties, and to maintain an optimal capital structure to reduce the cost of capital.

Notes to the Financial Statements

(b) Certain directors of the Company were sentenced of violating the Securities and Exchange Act by the Taiwan High Court (the “High Court”). With respect to the main content of the judgment, corresponding measures and the impact of the litigation on the operations, please refer to the following information:

(i) Main Content of the Judgment

On June 5, 2013, the Taipei District Prosecutors Office (the “Prosecutors Office”) filed a public prosecution against Chairman Chen and former Chairman Wang of the Company, and others, on the accusation of embezzlement, and claimed that between 2001 and 2011, the defendants have transferred more than NT$1.3 billion, from the funds of Company, to other companies that are effectively controlled by the defendants as follows: Dentsu Engineering Co. Ltd (“Dentsu”), Fukuo Engineering Co. Ltd., and Huayuan Engineering Co. Ltd. After the defendants presented numerous evidence to clarify the relevant facts during the trial, the Taipei District Court sentenced on August 31, 2015 (No. 102 Jin Chung Su Tzu 17) with the following main content: the court adopts the defendants' explanations and evidence regarding the NT$1.3 billion, as mentioned in the indictment, that the funds, except for part of them are payment for construction fee and the wages of the construction workers, the rest of the funds were used for repaying several incidental payments (collectively referred to as the “Package Fees”), previously paid by Dentsu and other companies. There is also no evidence provided that the defendants had committed an offence involving embezzlement or breach of trust; therefore, the court considers that the defendants were not guilty of each of the above-mentioned criminal charge. However, the court still held the defendants guilty for financial statement fraud due to failure to disclose in the financial statements of Dentsu and other companies and the Package Fees thereof. The defendants all appealed against the conviction while the public prosecutor also filed an appeal against the acquittal part of the verdict; and due to the death of Mr. Wang, the former Chairman of the Company, the High Court (No. 104 Jin Shang Chung Su Tzu 40) declared a dismissal judgment for Mr. Wang on July 25, 2017 with respect to the charges of non-arm's length transactions, breach of trust, and embezzlement. The High Court stated that there was no evidence to prove that the defendants, other than Mr. Wang, were guilty and the public prosecutor accepted the acquittal judgment without further appeal. As for the High Court's decision of guilty on the financial statement fraud, the sentences on two of the defendants were finalized because they were given probations and decided not to appeal; while Chairman Chen appealed to the Supreme Court, wherein the Supreme Court (No. 106 Tai Shang Tzu 3336), on July 25, 2018, reversed and remanded the case to the High Court whose further judgment (No. 107 Jin Shang Chung Geng Yi Tzu 8) on December 10, 2019 sentenced Mr. Chen guilty for misrepresented financial statements for certain years and guilty for violations of the Business Entity Accounting Act, as well as a five year probation; Chairman Chen filed an appeal while the SFIPC center also requested the prosecutor to appeal. The Supreme Court reversed and remanded the case to the High Court on July 17, 2020, moving the case for further proceedings in the High Court.

(ii) Corresponding Measures

(iii) Impact on the Operations

Since the occurrence of this case, the staff of the Company altogether have continued to stay on their posts and serve customers. The Company has also received support from proprietors and third party firms. The Company's revenue continues to grow, while the progress, collection and payment operations of projects remain normal. Current business and finances of the Company are quite robust, as the Company's operations have not been affected by any of the judicial events.

(iv) On December 5, 2013, based on the contents of the indictment, the SFIPC argued that it was inappropriate for the former three directors to hold such positions in the Company and appealed for court decision to dismiss the directors' positions.

As mentioned above, under the leadership of the former Chairman Wang, the operations and performances of the Company were extremely good. Apart from the record of the indictment, the SFIPC did not propose any specific evidence of the three directors' unsuitability for directorship. On February 6, 2014, the shareholders' meeting was held, and after discussion and resolutions, the majority of shareholders supported the decision for the three directors to continue to run the Company. In 2015, the shareholders' general meeting re-elected directors, and the three directors also won the majority of the shareholders' support for re-election. Under the Taipei District Court's ruling in June 18, 2015, the SFIPC lost the lawsuit. The SFIPC filed an appeal, but due to the death of Chairman Wang, the SFIPC withdrew part of the appeal and changed its petition to be dismissing two directors' positions from June 16, 2015 to June 15, 2018. The court of Second Instance decided in early February 2016 to dismiss the complaint of the SFIPC about changes of claims. The SFIPC appealed to the Court of Third Instance on March 28, 2016. The Supreme Court (No. 106 Tai Shang Tzu 2658) revoked the original Second Instance judgment on September 28, 2018, and remanded the case to the High Court. On April 28, 2020, the two directors were disqualified from being a director by the High Court order. Both directors filed appeals on May 18, 2020, but due to the resignation of director Lee on June 2, 2020, she withdrew the appeal on June 3 in the same year and the court's decision on director Lee became finalized as of the date thereof; while the appeal part regarding director Chen is currently under the trial of the Supreme Court. The financial and business operations of the Company have also not been affected by this lawsuit.

(v) According to the content of the indictment on January 27, 2014, the SFIPC filed a group lawsuit on behalf of the investor on the grounds that the Company's financial reports from the third quarter of 2008 to 2011 were misrepresented, requesting the Company, directors and former supervisors to jointly compensate the investors for the damage amounting to more than NT$243 million.

(c) The Company received the civil judgment from the Taiwan Taipei District Court on September 2, 2014 that the Company should pay the package fees of $104,559 thousand and the former Chairman Wang's salary from January 2001 to April 2012, as previously paid by Dentsu, amounting to $21,405 thousand.

As of the reporting date, the Company has yet to reimburse the abovementioned package fees, salary and related interests.
