In response tothe global supply chain restructuring and customers' demands for localized manufacturing, the Companycompleted the construction of new plants in Mexico and Poland as scheduled, served the expansion ofoverseas production capacity, merger with Hirschmann and responded to the pressure of customer supplychain price reduction, etc., which also caused the increase of the Company's operating costs. The Companyachieved operating profit of RMB 1.87 billion in 2024, a decrease of 14.01% YoY, resulting in acorresponding decrease in total profit and net profit attributable to shareholders of the listed company.(II) Changes in revenueThe Company realized total revenue of RMB 60.69 billion in 2024, down 0.17% from the previous year.Revenue from automotive electronics products increased by 16.24% YoY, while cloud and storageproducts saw a 13.35% increase. Conversely, revenue from communication products decreased by 3.36%,consumer electronics products by 0.27%, industrial products by 12.82%, and medical electronics productsby 11.21%.Changes in revenue by product category reflect changes in the global economy and end-market demand.The revenue of communication products and consumer electronics products decreased slightly YoY dueto the sales volume of important customers; the revenue of industrial products decreased YoY due tocustomer destocking and gradual recovery in demand; automotive electronics products mainly achievedYoY growth due to the Company's merger with Hirschman in 2024; the revenue growth of cloud andstorage products benefited from the significant growth in demand for server products driven by AI.(III) Changes in expenses and profitsAffected by the increase in material cost rate and the decrease in exchange-related gains, the Company'sgross profit margin in 2024 was 9.49%, a decrease of 0.09 percentage points YoY, and the operating profitmargin was 3.09%, a decrease of 0.50 percentage points YoY, and the Company achieved an operatingprofit of RMB 1.87 billion in 2024, a decrease of 14.01% YoY.In 2024, the total amount of the Company's selling expenses, administrative expenses, research anddevelopment expenses, and financial expenses was RMB 4.00 billion, showing a YoY increase of RMB424 million, with a growth rate of 11.86%.

Selling expenses increased by RMB 68 million YoY, with agrowth rate of 19.94%. Financial expenses increased by RMB 101 million YoY, showing a relatively largeincrease, mainly due to the increase in the net foreign exchange losses in 2024. The selling expenses,administrative expenses, and research and development expenses of the Company all showed varyingdegrees of growth. The main reason is that the financial data of Hirschmann was consolidated into theCompany's financial statements throughout 2024.

The rapidly increasing demand for nearshoring and friendly shoring inthe global supply chain has significantly stimulated investment and capacity expansion in Mexico, SouthEast Asia, India, Eastern Europe and other regions, and has also affected the transfer of capacity in theupstream supply chain, thus forming a new capacity scale and industrial chain cluster in the future. Inaddition, the impact of the US tariffs on China and Mexico will prompt the supply chain to invest in newproduction capacity in regions with geographical advantages, policy advantages, and cost advantages,reducing the business risks caused by the imposition of tariffs in specific regions.

(IV) Possible risks

√Applicable □ Not Applicable

1. The risk of weak macroeconomic recovery and insufficient demand

Universal Scientific Industrial (Shanghai) Co., Ltd. 2024 Annual Report

The EMS industry chain has shifted from supply chain-driven to demand-driven, and has a strongcorrelation with the macroeconomic environment. The Russian-Ukrainian war, geopolitics, inflation, thehigh interest rate environment and many other unfavorable factors affect global economic growth and endpoint demand. The continued development of AI technology is expected to drive further growth in demandin consumer electronics, computing power, data exchange, and other industries. The Company willcontinue to pay attention to the trend of the industrial chain structure, maintain close interaction withcustomers to grasp customer needs, and strengthen the collection and analysis of market information toreduce the impact of changes in product demand on the Company.

2. Industry competition risks

EMS industry is a fully competitive industry with numerous global manufacturers, but its overallconcentration is on the rise. Under the trend of supply chain reconstruction and economic and traderegionalization in the international market, the electronic manufacturing service industry and upstreamsupply chain in mainland China are facing more severe competitive pressure. The Company's new businessmodel of "global platform, localized service" combines its own advantages to compete with peers, but ifthe Company cannot maintain cost competitiveness and product technology advantages, market share andprofit margins will be squeezed.

3. Risk of high customer concentration

During the reporting period, the Company’s revenue from its top five customers accounted for 52.93% ofthe total revenue, showing high customer concentration. Such customers are internationally-renownedelectronic brands, and have established a long-term and stable cooperative relationship with USI to ensuresufficient business order. In spite of this, if the customer demand declines, or the Company fails to timelymeet the customer requirements in product R&D and design, product quality control, qualified suppliercertification, delivery date, etc., it may cause certain fluctuations in customer orders, thus adverselyaffecting the Company's business scale and operating performance. Therefore, the Company faces the riskof high customer concentration to a certain extent.

4. New product development and R&D investment risk

Technological progress continues to promote the upgrading and iteration of electronic products andequipment, and enterprises in the electronic manufacturing service industry have been under greatoperating pressure for a long time, such as product innovation, quality improvement, cost reduction,continuous investment, etc. Only by insisting on R&D investment and technological innovation canenterprises cope with the rapid changes in the market and competitive pressure. In the context of therestructuring of the supply chain, customers are also demanding higher standards for hardware R&D,software development, intelligent manufacturing, and low-carbon environmental protection. The companymust accelerate its R&D capabilities and strengthen their shortcomings in order to explore new businessopportunities. The Company faces the risk of insufficient R&D and innovation.

5. Transnational operation risk

To better serve major customers, the Company has arranged production, sales and logistics worldwide toquickly respond to the product delivery needs of major customers. As a result, the Company has 30production bases in 10 countries and regions. Overseas companies need to abide by the laws andregulations of the country and region where they are located when conducting business or establishinginstitutions abroad. If the laws, regulations, industrial policies or political and economic environment ofthe countries and regions where overseas business is located have undergone major changes, or there areunpredictable factors such as international tensions, wars, trade sanctions or other force majeure, it mayhave potential adverse effects on the normal business operation and sustainable development of overseascompanies. In addition, there are differences between operating sites located in various countries orregions in terms of accounting and taxation systems, business practices, company management systems,and corporate culture. If the relevant integration plan is not effectively implemented, there may be riskssuch as a lack of synergy from mergers and acquisitions or newly established companies, loss of corepersonnel, and decline in financial performance.

6. Exchange rate risk

The Company is a global electronic design and manufacturing service provider, most production facilitiesare located overseas as well as the main clients and suppliers are all overseas companies. The purchase of

Universal Scientific Industrial (Shanghai) Co., Ltd. 2024 Annual Report

materials, sales and shipments are mainly settled in foreign currencies (mainly USD). Companies usuallyuse foreign exchange hedging operations to deal with exchange rate fluctuations, but in the case ofsustained large fluctuations in exchange rates, large amounts of exchange gains and losses will still begenerated. In the face of the complex political and economic landscape and business environment acrossthe world, the Company will pay close attention to the changes in the foreign exchange market accordingto its own operational needs, adequately carry out foreign exchange hedging, and minimize exchange raterisks.

7. Emerging risks

The Company has a group risk management committee to identify internal and external risk factors thatmay affect the achievement of the Company's sustainable business objectives, evaluate the effectivenessof each risk level and related control activities, and implement appropriate measures and responses basedon the results of threat and risk assessment to ensure that risks can be effectively monitored.

(1) Geopolitical and regional conflict risks

The current global economy is still facing multiple challenges, with profound adjustments in the worldlandscape. Geopolitical and regional conflicts have brought more uncertainties to the macroeconomy andsupply chain, such as tariff increases, technological blockades, export controls, investment restrictions,technical barriers, and discriminatory subsidy policies. There are various restrictive policy measures thatmay lead to supply chain decoupling. The Company will conform to the development trend of "globaldemand, localized service", rationally layout global production capacity, and provide customers withdiverse manufacturing solutions with a global operation service system; at the same time, throughcontinuous strengthening of digital transformation, promoting the process of intelligent manufacturing inthe Company's global manufacturing service base, increasing R&D investment in key technologies andapplication fields, integrating internal resources of the group, technology mutual sharing and other waysto enhance product competitiveness and cost competitiveness, in manufacturing services, cooperativeresearch and development, product planning and design, supply chain strategy and other aspects ofdeepening business and investment cooperation, and developing closer long-term partnerships withcustomers.

(2) Policy risks

The current global economic situation and trade pattern are facing many uncertainties, and changes inregulations and policies in the places where companies operate may lead to increased business decision-making risks faced by enterprises. The Company will strengthen the monitoring of local regulations, taxpolicies, labor policies, and other laws and regulations, objectively judge their impact on the Company'soperations, formulate response strategies and take timely action plans, taking into account cost efficiencyand local policies and regulations, and strive to achieve the Company's business goals.

1. Classification of Current Liabilities and Non-Current Liabilities

(1) Reason for Accounting Policy Change

On October 25, 2023, the Ministry of Finance issued the Interpretation of Accounting Standards forBusiness Enterprises No. 17, which came into effect on January 1, 2024. Enterprises are required to adjustcomparable period information when first implementing the provisions of this interpretation.

(2) Main Content of the Accounting Policy Change

The Interpretation No. 17 revises and improves the classification principles for current liabilities and non-current liabilities under Accounting Standards for Business Enterprises No. 30—Presentation of FinancialStatements, as explained below:

It clarifies that if an enterprise does not have the substantive right to defer the settlement of a liability formore than one year after the balance sheet date, the liability shall be classified as a current liability. Thesubjective possibility of the enterprise exercising such a right does not affect the liquidity classification ofthe liability.For liabilities arising from loan arrangements, if the enterprise’s right to defer settlement depends onwhether it complies with the conditions specified in the loan arrangement (hereinafter referred to as thecontractual conditions), the classification of the liability’s liquidity on the balance sheet date shall bedetermined by distinguishing between situations before or on the balance sheet date and after the balancesheet date.It clarifies that if the counterparty to the liability has the option to settle the liability using the enterprise’sown equity instruments and such option is classified as an equity instrument and separately recognized,the relevant terms do not affect the liquidity classification of the liability.It specifies the disclosure requirements for loan arrangements with contractual conditions classified asnon-current liabilities, where the enterprise’s right to defer settlement depends on the contractualconditions to be met within one year after the balance sheet date.

(3) Impact on the Company

The company has evaluated and confirmed the classification principles for current liabilities and non-current liabilities under the Interpretation No. 17. After assessment, the company believes that thisaccounting policy change is a reasonable adjustment in accordance with the interpretation issued by the

Universal Scientific Industrial (Shanghai) Co., Ltd. 2024 Annual Report

Ministry of Finance and has no impact on the company’s financial position, operating results, or cashflows.

2. Accounting Treatment for Warranty-Type Quality Assurance Not Classified as a Single PerformanceObligation

(1) Reason for Accounting Policy Change

On December 6, 2024, the Ministry of Finance issued the Interpretation of Accounting Standards forBusiness Enterprises No.18, which provides clear explanations and regulations on the accountingtreatment for warranty-type quality assurance not classified as a single performance obligation. Theinterpretation came into effect upon issuance, allowing enterprises to implement it early in the year ofrelease.

(2) Main Content of the Accounting Policy Change

In accordance with Article 33 of Accounting Standards for Business Enterprises No. 14-Revenue and otherrelevant provisions, for warranty-type quality assurance not classified as a single performance obligation,enterprises shall recognize the estimated liability amount by debiting accounts such as “Cost of GoodsSold” and “Other Operating Costs” and crediting the “Estimated Liabilities” account. These amountsshall be presented in the “Operating Costs” line item in the income statement and in “Other CurrentLiabilities”, “Non-Current Liabilities Due Within One Year”, and “Estimated Liabilities” in the balancesheet. When first implementing this change, if the warranty-type quality assurance was previouslyrecorded under “Selling Expenses”, enterprises shall treat the changes in the relevant accounting accountsand financial statement presentation items as an accounting policy change and make retrospectiveadjustments in accordance with Accounting Standards for Business Enterprises No. 28-Changes inAccounting Policies, Accounting Estimates, and Corrections of Errors.

(3) Impact on the Company

Prior to the issuance of the Interpretation No. 18, the company recorded the amount of warranty-typequality assurance under “Selling Expenses”. After the issuance, the company retrospectively adjusted theamount of warranty-type quality assurance for 2023, reclassifying it from “Selling Expenses” to“Operating Costs”.The impact of this accounting policy change on the relevant accounts and amounts in the company’sfinancial statements is as follows:

Consolidated Income Statement
Unit: RMB Yuan
ItemAmount as Originally Reported for 2023Adjustments Due to Changes in Accounting PoliciesAmount as Restated for 2023
Operating Costs54,939,136,481.6926,710,213.1254,965,846,694.81
Selling Expenses367,994,662.03(26,710,213.12)341,284,448.91
Parent Company Income Statement
Unit: RMB Yuan
ItemAmount as Originally Reported for 2023Adjustments Due to Changes in Accounting PoliciesAmount as Restated for 2023
Operating Costs17,928,507,549.9812,556.3617,928,520,106.34
Selling Expenses77,474,832.09(12,556.36)77,462,275.73

After evaluation, the Company concludes that this change in accounting policies not only affects thepresentation items and amounts in the income statement but also marginally impacts financial metrics suchas gross profit margin. However, it has no material impact on the Company's financial position, operatingresults, or cash flows.

In our opinion, the accompanying financial statements are prepared and present fairly, in all materialrespects, the consolidated and Company's financial position as at 31 December 2024, and theconsolidated and the Company's results of operations and cash flows of USI for the year then endedin accordance with Accounting Standards for Business Enterprises.

II. Basis for Opinion

III. Key Audit Matters - continued

Cut-off of Revenue Recognition

Matter Description

As set out in Notes (V), 48 to the financial statements, the operating income in 2024 in theconsolidated financial statements of USI is RMB 60,690,651,098.10, which is significant. USI'ssales mainly include revenue from sale of goods , and the revenue is recognized at the time pointwhen the customer obtains the control over the commodity. Under different terms of sales contractsand trades, the time point of the transfer of commodity control is different. As revenue is one of thekey performance indicators of USI, and the time point for the transfer of control is different forvarious transaction modes in relation to revenue recognition, there is a risk that revenue is notrecognized in the appropriate accounting period. Therefore, we consider whether revenue is recordedin the appropriate accounting period as a key audit matter.

Audit Response

1. Understand the accounting policies for revenue recognition and key internal controls related tothe cut-off of revenue recognition of USI, evaluate the design and implementation of relevantinternal control, and test the effectiveness of its operation;

2. Check the material sales contracts, identify the contract terms and trade conditions related to the

time point of goods control transfer, and evaluate whether the time point of revenue recognitionof USI meets the provisions of the accounting standards for business enterprises;

3. Select samples for the sales transactions recorded before and after the balance sheet date, andcheck the accounting records, delivery orders, cargo right transfer documents and othersupporting documents related to revenue recognition, so as to evaluate whether the revenue isrecorded in the appropriate accounting period;

4. Review sales records after the balance sheet date for material sales returns and check relevant

supporting documentation to assess whether the related revenue was recorded in the correctaccounting period;

5. Analyze the fluctuation of revenue and gross margin before and after the year-end, and pay

attention to whether there is any abnormal change.

VI. Auditor's Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a wholeare free from material misstatement, whether due to fraud or error, and to issue an auditor's reportthat includes our opinion. Reasonable assurance is a high level of assurance, but is not a guaranteethat an audit conducted in accordance with China Standards on Auditing will always detect a materialmisstatement when it exists. Misstatements can arise from fraud or error and are considered materialif, individually or in the aggregate, they could reasonably be expected to influence the economicdecisions of users taken on the basis of these financial statements.

As part of an audit in accordance with China Standards on Auditing, we exercise professionaljudgment and maintain professional skepticism throughout the audit. We also:

(1) Identify and assess the risks of material misstatement of the financial statements, whether due tofraud or error, design and perform audit procedures responsive to those risks, and obtain auditevidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detectinga material misstatement resulting from fraud is higher than for one resulting from error, as fraud mayinvolve collusion, forgery, intentional omissions, misrepresentations, or the override of internalcontrol.

(2) Obtain an understanding of internal control relevant to the audit in order to design auditprocedures that are appropriate in the circumstances.

(3) Evaluate the appropriateness of accounting policies used and the reasonableness of accountingestimates and related disclosures made by the management.

(4) Conclude on the appropriateness of the management's use of the going concern basis ofaccounting and, based on the audit evidence obtained, whether a material uncertainty exists relatedto events or conditions that may cast significant doubt on USI's ability to continue as a going concern.If we conclude that a material uncertainty exists, we are required to draw attention in our auditor'sreport to the related disclosures in the financial statements or, if such disclosures are inadequate, tomodify our opinion. Our conclusions are based on the audit evidence obtained up to the date of ourauditor's report. However, future events or conditions may cause USI to cease to continue as a goingconcern.

(5) Evaluate the overall presentation (including the disclosures), structure and content of the financialstatements and whether the financial statements represent the underlying transactions and events ina manner that achieves fair presentation.

(6) Obtain sufficient appropriate audit evidence regarding the financial information of the entities orbusiness activities within USI to express an opinion on the financial statements. We are responsiblefor the direction, supervision and performance of the group audit. We remain solely responsible forour audit opinion.

VI. Auditor's Responsibilities for the Audit of the Financial Statements - continued

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

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

From the matters communicated with those charged with governance, we determine those mattersthat were of most significance in the audit of the financial statements of the current period and aretherefore the key audit matters. We describe these matters in our auditor's report unless law orregulation 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 adverseconsequences of doing so would reasonably be expected to outweigh the public interest benefits ofsuch communication.

NOTES TO THE FINANCIAL STATEMENTFOR THE YEAR ENDED 31 DECEMBER 2024

(II) BASIS OF PREPARATION OF FINANCIAL STATEMENTS - continued

3. Basis of accounting and principle of measurement - continued

Where the historical cost is adopted as the measurement basis, assets are recorded at the amount of cash or cashequivalents paid or the fair value of the consideration given to acquire them at the time of their acquisition.Liabilities are measured at the amount of proceeds or assets received or the contractual amounts for assuming thepresent obligation, or, at the amounts of cash or cash equivalents expected to be paid to settle the liabilities in thenormal course of business.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transactionbetween market participants at the measurements date, regardless of whether that price is directly observable orestimated using valuation technique. Regardless of whether that price is directly observable or estimated usinganother valuation technique, fair value for measurement and/or disclosure purposes in these financial statementsis determined on such a basis.

The capacity of market participants to realize the maximum profit of non-financial assets, or the capacity of otherparticipants who acquired non-financial assets to realize the maximum profit will be considered when measuringfair values of such non-financial assets.

For a financial asset taking the transaction price as its fair value on initial recognition and using valuationtechniques involving unobservable inputs in subsequent measurement of fair value, such valuation technique iscorrected in the valuation process, as to ensure that the initial recognition result determined by valuationtechniques is equal to the transaction price.

Fair value measurements are categorized into Level 1, 2 or 3 based on degree to which the inputs to the fair valuemeasurements are observable and the significance of the inputs to the fair value measurement in its entirety, whichare described as follows:

? Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that theentity can access at the measurement date;

? Level 2 inputs are inputs, other than inputs included within Level 1, that are observable for the asset orliability, either directly or indirectly;? Level 3 inputs are unobservable inputs for the asset or liability.

6. Accounting treatment of business combinations not involving enterprises under common control

6.1 Business combinations not involving enterprises under common control and goodwill

A business combination not involving enterprises under common control is a business combination in which allof the combining enterprises are not ultimately controlled by the same party or parties before and after thecombination.

The cost of combination is the aggregate of the fair values, at the acquisition date, of the assets given, liabilitiesincurred or assumed, and equity securities issued by the acquirer in exchange for control of the acquiree. Theintermediary expenses incurred by the acquirer in respect of auditing, legal services, valuation and consultancyservices, etc. and other associated administrative expenses attributable to the business combination are recognizedin profit or loss when they are incurred.

The acquiree's identifiable assets, liabilities and contingent liabilities, acquired by the acquirer in a businesscombination, that meet the recognition criteria shall be measured at fair value at the acquisition date.

Where the cost of combination exceeds the acquirer's interest in the fair value of the acquiree's identifiable netassets, the difference is treated as an asset and recognized as goodwill, which is measured at cost on initialrecognition. Where the cost of combination is less than the acquirer's interest in the fair value of the acquiree'sidentifiable net assets, the acquirer firstly reassesses the measurement of the fair values of the acquiree'sidentifiable assets, liabilities and contingent liabilities and measurement of the cost of combination. If after thatreassessment, the cost of combination is still less than the acquirer's interest in the fair value of the acquiree'sidentifiable net assets, the acquirer recognizes the remaining difference immediately in profit or loss for thecurrent period.

6. Accounting treatment of business combinations not involving enterprises under common control -

continued

6.1 Business combinations not involving enterprises under common control and goodwill - continued

If either the fair values of identifiable assets, liabilities and contingent liabilities acquired in a combination or thecost of business combination can be determined only provisionally by the end of the year in which the businesscombination was effected, the acquirer recognizes and measures the combination using those provisional values.Any adjustments to those provisional values within twelve months after the acquisition date are treated as if theyhad been recognized and measured on the acquisition date.

Goodwill arising on a business combination is measured at cost less accumulated impairment losses, and ispresented separately in the consolidated financial statements.

7. Criteria of control and preparation of consolidated financial statements

7.1 Criteria of control

Control is the power over the investee, exposures or rights to variable returns from its involvement with theinvestee, and the ability to use its power over the investee to affect the amount of the investor's returns. If changesof related facts and situations lead to changes of related elements of control, the Group will conduct reassessment.

7.2 Preparation of consolidated financial statements

The scope of consolidation in the consolidated financial statements is determined on the basis of control.

The combination of subsidiaries begins with the Group's control over the subsidiary, and ceases with the Group'slosing control of the subsidiary.

For a subsidiary disposed by the Group, the operating results and cash flows before the date of disposal (the datewhen control is lost) are included in the consolidated income statement and consolidated statement of cash flows,as appropriate.

For a subsidiary acquired through a business combination not involving enterprises under common control[or thecombined party under combination by merge, the operating results and cash flows from the acquisition date (thedate when control is obtained) are included in the consolidated income statement and consolidated statement ofcash flows, as appropriate.

The significant accounting policies and accounting periods adopted by the subsidiaries are determined based onthe uniform accounting policies and accounting periods set out by the Company.

Influence over the consolidated financial statements arising from significant intra-group transactions areeliminated on consolidation.

The portion of subsidiaries' equity that is not attributable to the Company is treated as minority interests andpresented as "minority interests" in the consolidated balance sheet within shareholders' equity. The portion of netprofits or losses of subsidiaries for the period attributable to minority interests is presented as "Profit or lossattributable to minority interests" in the consolidated income statement below the "net profit" line item.

When the amount of loss for the period attributable to the minority shareholders of a subsidiary exceeds theminority shareholders' portion of the opening balance of owners' equity of the subsidiary, the excess amount isstill allocated against minority interests.

Acquisition of minority interests or disposal of interest in a subsidiary that does not result in the loss of controlover the subsidiary is accounted for as equity transactions. The carrying amounts of the Company's interests andminority interests are adjusted to reflect the changes in their relative interests in the subsidiary. The differencebetween the amount by which the minority interests are adjusted and the fair value of the consideration paid orreceived is adjusted to capital reserve under owners' equity. If the capital reserve is not sufficient to absorb thedifference, the excess is adjusted against retained profits.

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

8. Classification of joint arrangements and accounting treatments of joint operations

A joint arrangement is classified into joint operation and joint venture, depending on the rights and obligations ofthe parties to the arrangement, which is assessed by considering the structure and the legal form of the arrangement,the terms agreed by the parties in the contractual arrangement and, when relevant, other facts and circumstances.A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rightsto the assets, and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangementwhereby the parties that have joint control of the arrangement have rights to the net assets of the joint arrangement.

The Group accounts for investments in joint ventures using equity method. Refer to Note (III) 16.3.2 "Long-termequity investments accounted for using the equity method" for details.

9. Recognition criteria of cash and cash equivalents

Cash comprises cash on hand and deposits that can be readily withdrawn on demand. Cash equivalents are theGroup's short-term (generally refers to expiration within three months from the date of purchase), highly liquidinvestments that are readily convertible to known amounts of cash and which are subject to an insignificant riskof changes in value.

10. Translation of transactions and financial statements denominated in foreign currencies

10.1 Transactions denominated in foreign currencies

A foreign currency transaction is recorded, on initial recognition, by applying an exchange rate that approximatesthe actual spot exchange rate on the date of the transaction. The exchange rate that approximates the actual spotexchange rate on the date of the transaction is calculated and determined according to the middle price of themarket exchange rate on the day before the period in which the transaction occurs (each month is divided intothree time periods: the first ten-day period of the month, the middle ten-day period of the month, and the last ten-day period of the month). The Group updates the exchange rate that approximates the actual spot exchange rateevery period.

At the balance sheet date, foreign currency monetary items are translated into functional currency using the spotexchange rates at the balance sheet date. Exchange differences arising from the differences between the spotexchange rates prevailing at the balance sheet date and those on initial recognition or at the previous balance sheetdate are recognized in profit or loss for the period, except that (1) exchange differences related to a specific-purpose borrowing denominated in foreign currency that qualify for capitalization are capitalized as part of thecost of the qualifying asset during the capitalization period; (2) exchange differences related to hedginginstruments for the purpose of hedging against foreign currency risks are accounted for using hedge accounting;

(3) exchange differences arising from changes in the carrying amounts (other than the amortized cost) of monetaryitems at fair value through other comprehensive income are recognized as other comprehensive income.

When the consolidated financial statements include foreign operation(s), if there is foreign currency monetaryitem constituting a net investment in a foreign operation, exchange difference arising from changes in exchangerates are recognized as "exchange differences arising on translation of financial statements denominated in foreigncurrencies " in other comprehensive income, and in profit and loss for the period upon disposal of the foreignoperation.

Foreign currency non-monetary items measured at historical cost are translated to the amounts in functionalcurrency at the spot exchange rates on the dates of the transactions. Foreign currency non-monetary itemsmeasured at fair value are re-translated at the spot exchange rate on the date the fair value is determined.Difference between the re-translated functional currency amount and the original functional currency amount istreated as changes in fair value (including changes of exchange rate) and is recognized in profit and loss or asother comprehensive income.

NOTES TO THE FINANCIAL STATEMENTFOR THE YEAR ENDED 31 DECEMBER 2024

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

10.2 Translation of financial statements denominated in foreign currencies

For the purpose of preparing the consolidated financial statements, financial statements of a foreign operation aretranslated from the foreign currency into RMB using the following method: assets and liabilities on the balancesheet are translated at the spot exchange rate prevailing at the balance sheet date; shareholders' equity items aretranslated at the spot exchange rates at the dates on which such items arose; all items in the income statement aswell as items reflecting the distribution of profits are translated at an exchange rates that approximate the actualspot exchange rates on the dates of the transactions; The difference between the translated assets and the aggregateof liabilities and shareholders' equity items is recognized as other comprehensive income and included inshareholders' equity.

Cash flows arising from a transaction in foreign currency and the cash flows of a foreign subsidiary are translatedat an exchange rate which approximates the spot exchange rate on the date of the cash flows. The effect ofexchange rate changes on cash and cash equivalents is regarded as a reconciling item and presented separately inthe cash flow statement as "effect of exchange rate changes on cash and cash equivalents".

The closing balances and the actual amounts of previous year are presented at the translated amounts in theprevious year's financial statements.

On disposal of the Group's entire interest in a foreign operation, or upon a loss of control over a foreign operationdue to disposal of certain equity investments or other reasons, the Group transfers the accumulated exchangedifferences arising on translation of financial statements of this foreign operation attributable to the owners' equityof the Company and presented under owners' equity, to profit or loss in the period in which the disposal occurs.

In case of a disposal of part equity investments or other reason leading to lower interest percentage in foreignoperations but does not result in the Group losing control over a foreign operation, the proportionate share ofaccumulated exchange differences arising on translation of financial statements are re-attributed to minorityinterests and are not recognized in profit and loss. For partial disposals of equity interests in foreign operationswhich are associates or joint ventures, the proportionate share of the accumulated exchange differences arising ontranslation of financial statements of foreign operations is reclassified to profit or loss.

11. Financial instruments

Financial assets and financial liabilities are recognized when the Group becomes a party to the contractualprovisions of the instrument.

For financial assets purchased or sold in a regular way, the Company recognizes assets acquired and liabilitiesassumed on a trade date basis, or derecognizes the assets sold on a trade date basis.

Financial assets and financial liabilities are initially measured at fair value (please refer to the relevant disclosureof basis of accounting and principle of measurement in Note (II) for methods in determination of fair value forfinancial assets and financial liabilities). For financial assets and financial liabilities at fair value through profit orloss, transaction costs are immediately recognized in profit or loss. For other financial assets and financialliabilities, transaction costs are included in their initial recognized amounts. Upon initial recognition of accountsreceivable that does not contain significant financing component or without considering the financing componentincluded in the contract with a term not exceeding one year under the Accounting Standards for BusinessEnterprises No. 14 - Revenue ("Revenue Standards"), the Group adopts the transaction price as defined in theRevenue Standards for initial measurement.

The effective interest method is a method that is used in the calculation of the amortized cost of a financial assetor a financial liability and in the allocation of the interest income or interest expense in profit or loss over therelevant period.

NOTES TO THE FINANCIAL STATEMENTFOR THE YEAR ENDED 31 DECEMBER 2024

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

11. Financial instruments - continued

The effective interest rate is the rate that exactly discounts estimated future cash flows through the expected lifeof the financial asset or financial liability to the carrying amount of the financial asset or to the amortized cost ofthe financial liability. When determining the effective interest rate, the Group estimates future cash flows byconsidering all contractual terms of the financial asset or financial liability including early repayment, extension,call option or other similar options etc. without considering future credit losses.

The amortized cost of a financial asset or a financial liability is the amount of a financial asset or a financialliability initially recognized net of principal repaid, plus or less the cumulative amortized amount arising fromamortization of the difference between the amount initially recognized and the amount at the maturity date usingthe effective interest method, net of cumulative loss allowance (only applicable to financial assets).

11.1 Classification, recognition and measurement of financial assets

After initial recognition, the Group's financial assets of various types are subsequently measured at amortizedcost, at fair value through other comprehensive income ("FVTOCI") or at fair value through profit or loss("FVTPL"), respectively.

If contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments ofprincipal and interest on the principal amount outstanding, and the financial asset is held within a business modelwhose objective is to hold financial assets in order to collect contractual cash flows, such asset is classified intofinancial assets measured at amortized cost, which include cash and bank balances, notes receivable, accountsreceivable, other receivables, non-current assets due within one year and long-term receivables and etc.

On initial recognition, the Group may irrevocably designate non-trading equity instruments, other than contingentconsideration recognized through business combination not involving enterprises under common control, asfinancial assets at FVTOCI on an individual basis. Such financial assets at FVTOCI are presented as other equityinstrument.

A financial asset is classified as held-for-trading if any of the following criteria is satisfied:

? It has been acquired principally for the purpose of selling it in near term.? On initial recognition, it is part of a portfolio of identifiable financial instruments that the Group managestogether and there is objective evidence that the Group has a recent actual pattern of short-term profit-taking.? It is a derivative that is neither a financial guarantee contract nor designated as an effective hedginginstrument.

Financial assets at FVTPL include financial assets classified as at FVTPL and financial assets designated as atFVTPL:

? Any financial assets that do not qualify for amortized cost measurement or measurement at FVTOCI or

designated at FVTOCI are classified into financial assets at FVTPL.? Upon initial recognition, in order to eliminate or significantly reduce accounting mismatch and qualified

hybrid financial instrument combines financial asset with embedded derivatives, the Group will irrevocably

designate it as financial liabilities at FVTPL.

Financial assets at FVTPL assets other than derivative financial assets are presented as "held-for-trading financialassets". Such financial assets at FVTPL which may fall due more than one year (or without fixed term) since thebalance sheet date and will be held more than one year are presented as other non-current financial assets.

11.1.1 Financial assets at amortized cost

The financial assets measured at amortized cost are subsequently measured at amortized cost using the effectiveinterest method. Gain or loss arising from impairment or derecognition is recognized in profit or loss.

The Group recognizes interest income from financial assets classified as financial assets at amortized cost usingthe effective interest method. The Group calculates and recognizes interest income through account balance offinancial assets multiplying effective interest, except for the following circumstances:

? For purchased or originated credit-impaired financial assets, the Group calculates and recognizes its interestincome based on amortized cost of the financial asset and the effective interest through credit adjustmentsince initial recognition.

? For purchased or originated financial assets without credit impairment incurred while with creditimpairment incurred in subsequent periods, the Group calculates and recognizes its interest income basedon amortized cost of the financial asset and the effective interest in subsequent periods. If the credit risk ofthe financial asset is reduced during subsequent periods and credit impairment does not exist, and theimprovement can be related to an event occurring after application of aforesaid provisions, the Group shallcalculate and recognize interest income through account balance of financial assets multiplying effectiveinterest.

11.1.2 Financial assets at FVTOCI

Changes in fair value of non-held-for-trading equity instrument investments designated as financial assets atFVTOCI are recognized in other comprehensive income. When the financial asset is derecognized, the cumulativegains or losses previously recognized in other comprehensive income are transferred and included in retainedearnings. During the period in which the Group holds the non-trading equity instrument, revenue from dividendsis recognized in profit or loss for the period when (1) the Group has established the right of collecting dividends;

(2) it is probable that the associated economic benefits will flow to the Group; and (3) the amount of dividendscan be measured reliably.

11.1.3 Financial assets at FVTPL

Financial assets at FVTPL are subsequently measured at fair value, with gains or losses on fair value changes andrelated dividends and interest income included in profit or loss for the period.

11.2 Impairment of financial instruments

The Group makes accounting treatment on impairment and recognizes loss allowance for expected credit losses("ECL") on financial assets measured at amortized cost and lease receivables.

The Group makes a loss allowance against amount of lifetime ECL of accounts receivable arising fromtransactions adopting the Revenue Standard as well as lease receivables arising from transactions adopting ASBENo. 21- Leases.

11. Financial instruments - continued

11.2 Impairment of financial instruments - continued

For other financial instruments, except for the purchased or originated credit-impaired financial assets, at eachbalance sheet date, the Group assess changes in credit risk of relevant financial instruments since initialrecognition. If the credit risk of the above financial instruments has increased significantly since initial recognition,the Group measures loss allowance based on the amount of full lifetime; if credit risk of the financial instrumenthas not increased significantly since initial recognition, the Group recognizes loss allowance based on 12-monthECL of the financial instrument. Increase in or reversal of credit loss allowance is included in profit or loss asloss/gain on impairment, except for financial assets classified as at fair value through other comprehensive income.For the financial assets classified as at FVTOCI, the Group recognizes credit loss allowance in othercomprehensive income and recognizes the loss/gain on impairment in profit or loss, while the Group does notdecrease the carrying amount of such financial assets in the balance sheet.

In the previous accounting period, the Group has measured the loss allowance according to the amount of ECLfor the entire period of the financial instrument, but on the current balance sheet date, the financial instrument isno longer a significant increase in credit risk since the initial recognition. The Group measures the loss allowancefor the financial instrument on the balance sheet date based on the amount of ECL in the next 12 months. Thereversal amount of the loss allowance formed is recognized in profit and loss for the period as an impairment gain.

11.2.1 Significant increase in credit risk

In assessing whether the credit risk has increased significantly since initial recognition, the Group compares therisk of a default occurring on the financial instrument as at the reporting date with the risk of a default occurringon the financial instrument as at the date of initial recognition.

In particular, the following information is taken into account when assessing whether credit risk has increasedsignificantly:

(1) Significant changes in internal price indicators as a result of a change in credit risk;

(2) An actual or expected significant change in the financial instrument's external credit rating;

(3) An actual or expected decrease in the internal credit rating for the debtor;

(4) Adverse changes in business, financial or economic conditions that are expected to cause a significant

decrease in the debtor's ability to meet its debt obligations;

(5) An actual or expected significant change in the operating results of the debtor;

(6) Significant adverse changes in regulatory, economic, or technological environment of the debtor;

(7) Significant changes in circumstances expected to reduce the debtor's economic incentive to make scheduled

contractual payments;

(8) Significant changes in expected performance and repayment of the debtor;

(9) Changes in the Group's credit management approach in relation to the financial instrument.

No matter whether credit risk has increased significantly or not subsequent to aforementioned assessment, theGroup considers credit risk of financial instruments has increased significantly when contractual payments offinancial instruments past due over 30 days (inclusive).

The Group assumes that the credit risk on a financial instrument has not increased significantly since initialrecognition if the financial instrument is determined to have lower credit risk at the balance sheet date. A financialinstrument is determined to have lower credit risk if: i) it has a lower risk of default, ii) the borrower has a strongcapacity to meet its contractual cash flow obligations in the near term and iii) adverse changes in economic andbusiness conditions in the longer term may, but will not necessarily, reduce the ability of the borrower to fulfil itscontractual cash flow obligations.

11.2 Impairment of financial instruments - continued

11.2.2 Credit-impaired financial assets

When the Group expected occurrence of one or more events which may cause adverse impact on future cash flowsof a financial asset, the financial asset will become a credit-impaired financial assets. Objective evidence that afinancial asset is impaired includes but not limited to the following observable events:

(1) Significant financial difficulty of the issuer or debtor;

(2) Breach of contract by the debtor, such as a default or delinquency in interest or principal payments;

(3) The creditor, for economic or contractual reasons relating to the debtor's financial difficulty, has granted tothe debtor a concession that the creditor would not otherwise consider;

(4) it is becoming probable that the borrower will enter bankruptcy or other financial reorganization;

(5) Purchase or originate a financial asset with a large scale of discount, which reflects facts of credit lossincurred.

Whatever the aforementioned assessment results are, the Group presumes that the financial instruments havedefaulted when contractual payments of financial instruments past due over 90 days (inclusive).

11.2.3 Determination of expected credit loss

The Group determines the ECL of relevant financial instruments using the following method:

? For a financial asset and a lease receivable, a credit loss is the present value of the difference between thecontractual cash flows that are due to the Group under the contract and the cash flows that the Group expectsto receive;

? For credit-impaired financial assets other than the purchased or originated credit-impaired financial assets

at the balance date, credit loss is difference between the carrying amount of financial assets and the presentvalue of expected future cash flows discounted at original effective interest rate.

The factors reflected in methods of measurement of expected credit losses include an unbiased and probability-weighted amount that is determined by evaluating a range of possible outcomes; time value of money; reasonableand supportable information about past events, current conditions and forecasts on future economic status atbalance sheet date without unnecessary additional costs or efforts.

11.2.4 Write-down of financial assets

When the Group will no longer reasonably expect that the contractual cash flows of financial assets can becollected in aggregate or in part, the Group will directly write down the carrying amount of the financial asset,which constitutes derecognition of relevant financial assets.

11.3 Transfer of financial assets

The Group will derecognize a financial asset if one of the following conditions is satisfied: (i) the contractualrights to the cash flows from the financial asset expire; (ii) the financial asset has been transferred and substantiallyall the risks and rewards of ownership of the financial asset is transferred to the transferee; or (iii) although thefinancial asset has been transferred, the Group neither transfers nor retains substantially all the risks and rewardsof ownership of the financial asset but has not retained control of the financial asset.

NOTES TO THE FINANCIAL STATEMENTFOR THE YEAR ENDED 31 DECEMBER 2024

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

11. Financial instruments - continued

11.3 Transfer of financial assets - continued

If the Group neither transfers nor retains substantially all the risks and rewards of ownership of a financial asset,and it retains control of the financial asset, the Group will recognize the financial asset to the extent of itscontinuing involvement in the transferred financial asset and recognize an associated liability. The Group willmeasure relevant liabilities as follows:

? For transferred financial assets carried at amortized cost, the carrying amount of relevant liabilities is thecarrying amount of financial assets transferred with continuing involvement less amortized cost of theGroup's retained rights (if the Group retains relevant rights upon transfer of financial assets) with additionof amortized cost of obligations assumed by the Group (if the Group assumes relevant obligations upontransfer of financial assets). Relevant liabilities are not designated as financial liabilities at fair valuethrough profit or loss.

? For transferred financial assets carried at fair value, the carrying amount of relevant financial liabilities isthe carrying amount of financial assets transferred with continuing involvement less fair value of theGroup's retained rights (if the Group retains relevant rights upon transfer of financial assets) with additionof fair value of obligations assumed by the Group (if the Group assumes relevant obligations upon transferof financial assets). Accordingly, the fair value of relevant rights and obligations shall be measured on anindividual basis.

For a transfer of a financial asset in its entirety that satisfies the derecognition criteria, the difference between (1)the carrying amount of the financial asset transferred at the derecognition date; and (2) the sum of theconsideration received from the transfer of financial assets and any cumulative gain or loss allocated to the partderecognized which has been previously recognized in other comprehensive income, is recognized in profit orloss. If the financial assets transferred by the Group are designated as equity instrument investments at fair valuethrough other comprehensive income that are not held for trading, the cumulative gains or losses previouslyrecognized in other comprehensive income are transferred out and included in retained earnings.

If a part of the transferred financial asset qualifies for derecognition, the overall carrying amount of the financialasset prior to transfer is allocated between the part that continues to be recognized and the part that is derecognized,based on the respective fair value of those parts at the date of transfer. The difference between (1) the carryingamount allocated to the part derecognized on the date of derecognition; and (2) the sum of the considerationreceived for the part derecognized and any cumulative gain or loss allocated to the part derecognized which hasbeen previously recognized in other comprehensive income, is recognized in profit or loss. If the financial assetstransferred by the Group are designated as equity instrument investments at fair value through othercomprehensive income that are not held for trading, the cumulative gains or losses previously recognized in othercomprehensive income are transferred out and included in retained earnings.

For a transfer of a financial asset in its entirety that does not satisfy the derecognition criteria, the Group willcontinue to recognize the transferred financial asset in its entirety and recognize the consideration received asfinancial liabilities.

11.4 Classification of financial liabilities and equity instruments

The Group classifies the financial instrument or its components into financial liabilities or equity instruments atinitial recognition on the basis of the terms of the contract of the financial instruments, the economic substanceas well as legal form reflected, and the definition of financial liabilities or equity instruments.

11.4.1 Classification, recognition and measurement of financial liabilities

On initial recognition, financial liabilities are classified into financial liabilities at FVTPL and other financialliabilities.

NOTES TO THE FINANCIAL STATEMENTFOR THE YEAR ENDED 31 DECEMBER 2024

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

11. Financial instruments - continued

11.4 Classification of financial liabilities and equity instruments - continued

11.4.1 Classification, recognition and measurement of financial liabilities - continued

11.4.1.1 Financial liabilities at FVTPL

Financial liabilities at FVTPL include financial liabilities held for trading (including derivatives that are financialliabilities) and financial liabilities designated as at FVTPL. Except that the derivative financial liability ispresented separately, financial liabilities at FVTPL are presented as financial liabilities held-for-trading.

A financial liability is classified as held-for-trading if any of the following criteria is satisfied:

? It has been incurred principally for the purpose of repurchasing it in the near term.? On initial recognition, it is part of a portfolio of identified financial instruments that the Group managestogether and there is objective evidence that the Group has a recent actual pattern of short-term profit-taking.? It is a derivative that is neither a financial guarantee contract nor designated as an effective hedginginstrument.

On initial recognition, financial liabilities that meet one of the following conditions are designated as financialliabilities at FVTPL: (1) Such designation eliminates or significantly reduces accounting mismatch; (2) Thefinancial liability forms part of a group of financial liabilities or a group of financial assets and financial liabilities,which is managed and its performance is evaluated on a fair value basis, in accordance with the documented riskmanagement or investment strategy, and information about the grouping is reported to key management personnelon that basis; (3) The qualified hybrid financial instrument combines financial liability with embedded derivatives.

Held-for-trading financial liabilities are subsequently measured at fair value, and any gains or losses arising fromchanges in fair value and any dividend or interest income earned on the financial liabilities are recognized inprofit or loss.

For a financial liability designated as at FVTPL, the amount of changes in the fair value of the financial liabilitythat are attributable to changes in the credit risk of that liability shall be presented in other comprehensive income,while other changes in fair values are included in profit or loss for the current period. Upon the derecognition ofsuch financial liability, the accumulated amount of changes in fair value that are attributable to changes in thecredit risk of that liability, which was recognized in other comprehensive income, is transferred to retainedearnings. Any dividend or interest expense on the financial liabilities is recognized in profit or loss. If theaccounting treatment for the impact of the change in credit risk of such financial liability in the above ways wouldcreate or enlarge an accounting mismatch in profit or loss, the Group shall present all gains or losses on thatliability (including the effects of changes in the credit risk of that liability) in profit or loss for the period.

11.4.1.2 Other financial liabilities

Other financial liabilities except for the financial liabilities arising from the transferred financial assets that do notqualify for derecognition or financial liabilities arising from continuing involvement in the transferred financialasset are classified as financial liabilities measured at amortized cost, and are subsequently measured at amortizedcost, with gain or loss arising from derecognition or amortization recognized in profit or loss.

11.4.1 Classification, recognition and measurement of financial liabilities - continued

11.4.1.2 Other financial liabilities - continued

If the Group modifies or renegotiates the contract with the counterparty and the financial liability subsequentlymeasured at amortized cost is not derecognized, but the cash flow of the contract changes, the Group shall re-calculate the carrying amount of the financial liability and recognize the relevant gains or losses in profit or lossof the period. The re-calculated carrying amount of the financial liability shall be determined by the Groupaccording to the cash flow of the renegotiated or modified contract based on the present value discounted at theoriginal effective interest rate of the financial liability. For all the costs or expenses arising from the modificationor renegotiation of the contract, the Group shall adjust the modified carrying amount of the financial liability andamortize them within the remaining term of the financial liability.

11.4.2 Derecognition of financial liabilities

The Group recognizes a financial liability (or part of it) only when the underlying present obligation (or part ofit) is discharged. An agreement between the Group (an existing borrower) and an existing lender to replace theoriginal financial liability with a new financial liability with substantially different terms is accounted for as anextinguishment of the original financial liability and the recognition of a new financial liability.

When the Group derecognizes a financial liability or a part of it, it recognizes the difference between the carryingamount of the financial liability (or part of the financial liability) derecognized and the consideration paid(including any non-cash assets transferred or new financial liabilities assumed) in profit or loss.

11.4.3 Equity instruments

An equity instrument is any contract that evidences a residual interest in the assets of the Group after deductingall of its liabilities. Equity instruments issued (including refinanced), repurchased, sold and cancelled by theGroup are recognized as changes of equity. Change of fair value of equity instruments is not recognized by theGroup. Transaction costs related to equity transactions are deducted from equity.

The Group recognizes the distribution to holders of the equity instruments as distribution of profits, and dividendspaid do not affect total amount of shareholders equity.

11.5 Derivatives and embedded derivatives

Derivatives include forward exchange contracts, resale option and early redemption option for convertible bonds,etc. Derivatives are initially measured at fair value at the date when the derivative contracts are entered into andare subsequently re-measured at fair value.

Derivatives embedded in hybrid contracts that contain financial asset hosts are not separated. The entire hybridcontract is classified and subsequently measured in its entirety as either amortized cost or fair value as appropriate.

If the host contract included in the hybrid contract is not a financial asset and meet all of the following criteria,the embedded derivative shall be separated from the hybrid contract by the Group and treated as a stand-alonederivative.

(1) The economic characteristics and risks of the embedded derivative are not highly related to the economiccharacteristics and risks of the host contract;

(2) A separate instrument with the same terms as the embedded derivative would meet the definition of aderivative; and

NOTES TO THE FINANCIAL STATEMENTFOR THE YEAR ENDED 31 DECEMBER 2024

(3) The hybrid instrument is not designated as a financial asset or financial liability at FVTPL.

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

11. Financial instruments - continued

11.5 Derivatives and embedded derivatives - continued

If the embedded derivative is separated from the hybrid contract, the host contract shall be accounted for inaccordance with the applicable standards. If the Group is unable to measure reliably the fair value of an embeddedderivative on the basis of its terms and conditions, the fair value of the embedded derivative is the differencebetween the fair value of the hybrid contract and the fair value of the host contract. If the Group is still unable tomeasure the fair value of the embedded derivative separately either at acquisition or at a subsequent balance sheetdate after the above methods are applied, it designates the entire hybrid contract as a financial instrument at fairvalue through profit or loss.

11.6 Offsetting financial assets and financial liabilities

Where the Group has a legal right that is currently enforceable to set off the recognized financial assets andfinancial liabilities, and intends either to settle on a net basis, or to realize the financial asset and settle the financialliability simultaneously, a financial asset and a financial liability shall be offset and the net amount is presentedin the balance sheet. Except for the above circumstances, financial assets and financial liabilities shall be presentedseparately in the balance sheet and shall not be offset.

11.7 Compound instruments

Convertible bonds issued by the Group that contain both the liability, the conversion option, the resale option andearly redemption option are classified separately into respective items on initial recognition. Conversion optionthat is settled by the exchange of a fixed amount of cash or another financial asset for a fixed number of theCompany's own equity instruments is an equity instrument.

At the date of issue, the liability, resale option derivatives and early redemption option derivatives are initiallymeasured at fair value. The difference between the gross proceeds of the issue of the convertible bonds and thefair value assigned to the liability, resale option derivatives and early redemption option derivatives, representingthe conversion option for the holder to convert the bonds into equity instrument, is included in other equityinstruments.

In subsequent periods, the liability component of the convertible bonds is carried at amortized cost using theeffective interest method. The resale option derivatives and early redemption option derivatives are measured atfair value with changes in fair value recognized in profit or loss. The conversion option classified as equityinstruments remains in equity instruments. No gain or loss is recognized in profit or loss upon conversion orexpiration of the option.

Transaction costs incurred for the issue of the convertible bonds are allocated to the liability, equity instruments,resale option derivative components and early redemption option derivative components in proportion to theirrespective fair values. Transaction costs relating to the resale option derivative components and early redemptionoption are charged to profit or loss. Transaction costs relating to the liability component are included in thecarrying amount of the liability component and amortized over the period of the convertible loan notes using theeffective interest method. Transaction costs relating to the equity instruments component are charged directly toequity instruments.

12. Notes receivable

12.1 Categories of portfolios for which loss provision is assessed on a portfolio basis according to credit riskcharacteristics and the basis for determination

The Group believes that the credit risk of the bank acceptances held by the Group was insignificant due to thehigh credit rating of the accepting banks. Therefore, no provision for credit loss was made.

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

13. Accounts receivable

13.1 Categories of portfolios for which bad debt provision is assessed on a portfolio basis according to credit riskcharacteristics and the basis for determination

The Group classifies accounts receivable into different groups based on common risk characteristics. Commoncredit risk characteristics include the aging of accounts receivable.

13.2 Aging calculation method for portfolio of credit risk characteristics recognized based on aging

The Group uses the aging of accounts receivable as a credit risk characteristic to determine its credit loss usingan impairment matrix. The aging is calculated from the date of obtaining the right to collect the contractualpayment.

13.3 Judgement criteria for loss provision assessed on an individual basis

The Group assesses the credit risk of the accounts receivable from the debtor with significant financial difficultieson an individual basis based on the risk assessment and judgement of the management.

14. Other receivables

14.1 Determination of ECL on other receivables and accounting treatment

The Group determines credit losses on other receivables on an individual asset basis.

15. Inventories

15.1 Categories of inventories, valuation method of inventories upon delivery, inventory count system andamortization method for reusable materials

15.1.1 Categories of inventories

The Group's inventories mainly include raw materials, work in progress, finished goods, reusable materials, etc.Inventories are initially measured at cost. Cost of inventories comprises all costs of purchase, costs of conversionand other expenditures incurred in bringing the inventories to their present location and condition.

15.1.2 Valuation method of inventories upon delivery

The actual cost of inventories upon delivery is calculated using the weighted average method.

15.1.3 Inventory count system

The perpetual inventory system is maintained for stock system.

15.1.4 Amortization method for reusable materials

Reusable materials are amortized using the multiple-stage amortization method.

15.2 Recognition criteria and provision methods for decline in value of inventories

At the balance sheet date, inventories are measured at the lower of cost and net realizable value. If the netrealizable value is below the cost of inventories, a provision for decline in value of inventories is made.

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

15. Inventories - continued

15.2 Recognition criteria and provision methods for decline in value of inventories - continued

Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs ofcompletion, the estimated costs necessary to make the sale and relevant taxes. Net realizable value is determinedon the basis of clear evidence obtained, and takes into consideration the purposes of holding inventories and effectof post balance sheet events.

After the provision for decline in value of inventories is made, if the circumstances that previously causedinventories to be written down below cost no longer exist so that the net realizable value of inventories is higherthan their cost, the original provision for decline in value is reversed and the reversal is included in profit or lossfor the period.

The Group makes provision for decline in value of inventories on an individual basis (differentiated by productand material model), please refer to Note V, 7 for the basis of determining the net realizable value of each typeof inventories.

16. Long-term equity investments

16.1 Determination criteria of joint control and significant influence

Control is achieved when the Group has the power over the investee, is exposed or, has the rights to, variablereturns from its involvement with the investee; and has the ability to use its power to affect its return. Joint controlis the contractually agreed sharing of control over an economic activity, and exists only when the strategicfinancial and operating policy decisions relating to the activity require the unanimous consent of the partiessharing control. Significant influence is the power to participate in the financial and operating policy decisions ofthe investee but is not control or joint control over those policies. When determining whether an investingenterprise is able to exercise control or significant influence over an investee, the effect of potential voting rightsof the investee (for example, warrants and convertible debts) held by the investing enterprises or other parties thatare currently exercisable or convertible shall be considered.

16.2 Determination of initial investment cost

For a long-term equity investment acquired through business combination not involving enterprises undercommon control, the investment cost of the long-term equity investment is the cost of acquisition at the date ofcombination.

The expenses incurred by the acquirer or in respect of auditing, legal services, valuation and consultancy servicesand other associated administrative expenses attributable to the business combination are recognized in profit orloss when they are incurred.

Long-term equity investment acquired otherwise than through a business combination is initially measured at itscost.

16.3 Subsequent measurement and recognition of profit or loss

16.3.1 Long-term equity investment accounted for using the cost method

The Company's separate financial statements adopted cost method to account for the long-term equity investmentsof subsidiaries. A subsidiary is an investee that is controlled by the Group.

Under the cost method, a long-term equity investment is measured at initial investment cost. When additionalinvestment is made or the investment is recouped, the cost of the long-term equity investment is adjustedaccordingly. Investment income is recognized in the period in accordance with the attributable share of cashdividends or profit distributions declared by the investee.

16.3 Subsequent measurement and recognition of profit or loss - continued

16.3.2 Long-term equity investment accounted for using the equity method

The Group accounts for investment in associates and joint ventures using the equity method. An associate is anentity over which the Group has significant influence and a joint venture is an entity over which the Groupexercises joint control along with other investors.

Under the equity method, where the initial investment cost of a long-term equity investment exceeds the Group'sshare of the fair value of the investee's identifiable net assets at the time of acquisition, no adjustment is made tothe initial investment cost. Where the initial investment cost is less than the Group's share of the fair value of theinvestee's identifiable net assets at the time of acquisition, the difference is recognized in profit or loss for theperiod, and the cost of the long-term equity investment is adjusted accordingly.

Under the equity method, the Group recognizes its share of the net profit or loss and other comprehensive incomeof the investee for the period as investment income and other comprehensive income for the period. Meanwhile,carrying amount of long-term equity investment is adjusted: the carrying amount of long-term equity investmentis decreased in accordance with its share of the investee's declared profit or cash dividends; Other changes inowners' equity of the investee other than net profit or loss and other comprehensive income are correspondinglyadjusted to the carrying amount of the long-term equity investment, and recognized in the capital reserve. TheGroup recognizes its share of the investee's net profit or loss based on the fair value of the investee's individualidentifiable assets, etc. at the acquisition date after making appropriate adjustments. When the investors'accounting policies and accounting period are inconsistent with those of the Company, the Company recognizesinvestment income and other comprehensive income after making appropriate adjustments to conform to theCompany's accounting policies and accounting period. However, unrealized gains or losses resulting from theGroup's transactions with its associates and joint ventures, which do not constitute a business, are eliminatedbased on the proportion attributable to the Group and then investment gains or losses or is recognized. However,unrealized losses are not eliminated if they result from the Group's transactions with its associates and jointventures which represent impairment losses on the transferred assets.

The Group discontinues recognizing its share of net losses of the investee after the carrying amount of the long-term equity investment together with any long-term interests that in substance form part of its net investment inthe investee is reduced to zero. If the Group has incurred obligations to assume additional losses of the investee,a provision is recognized according to the expected obligation, and recorded as investment loss for the period.Where net profits are subsequently made by the investee, the Group resumes recognizing its share of those profitsonly after its share of the profits exceeds the share of losses previously not recognized.

16.4 Disposal of long-term equity investments

On disposal of a long-term equity investment, the difference between the proceeds actually received andreceivable and the carrying amount is recognized in profit or loss for the period.

17. Investment properties

Investment property is property held to earn rentals or for capital appreciation or both, including buildings leasedout.

An investment property is measured initially at cost. Subsequent expenditures incurred for such investmentproperty are included in the cost of the investment property if it is probable that economic benefits associatedwith an investment property will flow to the Group and the subsequent expenditures can be measured reliably.Other subsequent expenditures are recognized in profit or loss in the period in which they are incurred.

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

17. Investment properties - continued

The Group uses the cost model for subsequent measurement of investment property, and adopts the straight-linemethod for depreciation over its useful life. The depreciation method, depreciation period, estimated residualvalue rate and annual depreciation rate of each category of investment properties are as follows:

CategoryDepreciation methodDepreciation period (years)Residual value rate (%)Annual depreciation rate (%)
BuildingsStraight-line method35 years-2.86

An investment property is derecognized upon disposal or when the investment property is permanently withdrawnfrom use and no future economic benefits are expected from its disposals.

When an investment property is sold, transferred, retired or damaged, the Group recognizes the amount of anyproceeds on disposal net of the carrying amount and related taxes in profit or loss for the period.

18. Fixed Assets

18.1 Recognition criteria

Fixed assets are tangible assets that are held for use in the production or supply of goods or services, for rental toothers, or for administrative purposes, and have useful lives of more than one accounting year. A fixed asset isrecognized only when it is probable that economic benefits associated with the asset will flow to the Group andthe cost of the asset can be measured reliably. Fixed assets are initially measured at cost.

Subsequent expenditures incurred for the fixed asset are included in the cost of the fixed asset and if it is probablethat economic benefits associated with the asset will flow to the Group and the subsequent expenditures can bemeasured reliably. Meanwhile the carrying amount of the replaced part is derecognized. Other subsequentexpenditures are recognized in profit or loss in the period in which they are incurred.

18.2 Depreciation method

A fixed asset other than land operated overseas is depreciated over its useful life using the straight-line methodsince the month subsequent to the one in which it is ready for intended use.

Land operated overseas is not depreciated. The depreciation method, depreciation period, estimated residual valuerate and annual depreciation rate of other categories of fixed assets are as follows:

CategoryDepreciation period (years)Residual value rate (%)Annual depreciation rate (%)
Buildings12-35 years-2.86-8.33
Machinery and equipment3-8 years-12.50-33.33
Transportation vehicles2-6 years-16.67-50.00

18. Fixed Assets - continued

18.3 Other descriptions

If a fixed asset is upon disposal or no future economic benefits are expected to be generated from its use ordisposal, the fixed asset is derecognized. When a fixed asset is sold, transferred, retired or damaged, the amountof any proceeds on disposal of the asset net of the carrying amount and related taxes is recognized in profit or lossfor the period.

The Group reviews the useful life and estimated net residual value of a fixed asset and the depreciation methodapplied at least once at each financial year-end, and account for any change as a change in an accounting estimate.

19. Construction in progress

Construction in progress is measured at its actual costs. The actual costs include various construction expendituresduring the construction period, borrowing costs capitalized before it is ready for intended use and other relevantcosts. Construction in progress is not depreciated.

Construction in progress is transferred to a fixed asset when it is ready for intended use. The criteria and timepoints for the transfer of various types of construction in progress to fixed assets are as follows:

CategoryCriteria for transfer to fixed assetsTime points for transfer to fixed assets
BuildingsConstruction work is completed, meets intended design requirements and satisfies acceptance quality criteriaWhen acceptance criteria are met
Machinery and equipment, electronic equipment, fixtures and furniture, transportation vehicles, etc. to be installed(1) Relevant equipment and other supporting facilities have been installed; or (2) The equipment can maintain normal and stable operation for a period of time after commissioningWhen the asset utilization notice is obtained or when acceptance criteria are met

20. Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of qualifying asset arecapitalized when expenditures for such asset and borrowing costs are incurred and activities relating to theacquisition, construction or production of the asset that are necessary to prepare the asset for its intended use orsale have commenced. Capitalization of borrowing costs ceases when the qualifying asset being acquired,constructed or produced becomes ready for its intended use or sale. Other borrowing costs are recognized as anexpense in the period in which they are incurred.

Where funds are borrowed under a specific-purpose borrowing, the amount of interest to be capitalized is theactual interest expense incurred on that borrowing for the period less any bank interest earned from depositingthe borrowed funds before being used on the asset or any investment income on the temporary investment of thosefunds. Where funds are borrowed under general-purpose borrowings, the Group determines the amount of interestto be capitalized on such borrowings by applying a capitalization rate to the weighted average of the excess ofcumulative expenditures on the asset over the amounts of specific-purpose borrowings. The capitalization rate isthe weighted average of the interest rates applicable to the general-purpose borrowings.

21. Intangible assets

21.1 Determination basis, estimation, amortization method and review procedure of useful life

Intangible assets include software, patents, trademarks, land use rights and customer relations, etc.

An intangible asset is measured initially at cost. When an intangible asset with a finite useful life is available foruse, its original cost less any accumulated impairment losses is amortized over its estimated useful life using thestraight-line method. An intangible asset with an indefinite useful life is not amortized.

The amortization methods, useful lives, and residual value rates of each class of intangible assets are as follows:

CategoryAmortization methodUseful life (Years)Residual value rate (%)
Land use rightStraight-line method50 years-
SoftwareStraight-line method3-10 years-
PatentsStraight-line method3-20 years-
TrademarksStraight-line method10 years-
Customer relationStraight-line method16 years-

For an intangible asset with a finite useful life, the Group reviews the useful life and amortization method at theend of the year, and makes adjustments when necessary.

21.2 Attribution scope and related accounting treatments of research and development expenditure

All of the Group's research and development expenditures do not meet the conditions for capitalization and arecharged to profit or loss for the period when incurred.

Attribution scope of research and development expenditure includes the salaries, wages and welfare expenses ofthe personnel directly engaged in research and development activities, material expenses directly consumed inresearch and development activities, depreciation expenses of apparatus and equipment relevant to research anddevelopment activities, rental and maintenance expenses of research and development sites, travel, transportationand communication expenses necessary for research and experimental development, etc.

22. Impairment of long-term assets

The Group reviews the long-term equity investments, investment properties measured using the cost model, fixedassets, construction in progress, right-of-use assets and intangible assets with a finite useful life at each balancesheet date to determine whether there is any indication that they have suffered an impairment loss. If animpairment indication exists, the recoverable amount is estimated. Intangible assets with an indefinite useful lifeand not yet available for use are tested for impairment annually, irrespective of whether there is any indicationthat the assets may be impaired.

Recoverable amount is estimated on individual basis. If it is not practical to estimate the recoverable amount ofan individual asset, the recoverable amount of the asset group to which the asset belongs will be estimated. Therecoverable amount of an asset or asset group is the higher of its fair value less costs of disposal and the presentvalue of the future cash flows expected to be derived from the asset or asset group.

If such recoverable amount is less than its carrying amount, a provision for impairment losses in respect of thedeficit is recognized in profit or loss for the period.

NOTES TO THE FINANCIAL STATEMENTFOR THE YEAR ENDED 31 DECEMBER 2024

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

22. Impairment of long-term assets - continued

Goodwill is tested for impairment at least at the end of each year. For the purpose of impairment testing, goodwillis considered together with the related assets group(s), i.e., goodwill is reasonably allocated to the related assetsgroup(s) or each of assets group(s) expected to benefit from the synergies of the combination. An impairment lossis recognized if the recoverable amount of the assets group or sets of assets groups (including goodwill) is lessthan its carrying amount. The impairment loss is firstly allocated to reduce the carrying amount of any goodwillallocated to such assets group or sets of assets groups, and then to the other assets of the group on the pro-ratabasis of the carrying amount of each asset (other than goodwill) in the group.

Once an impairment loss of the above-mentioned assets is recognized, it will not be reversed in any subsequentperiod.

23. Long-term prepaid expenses

Long-term prepaid expenses represent expenses incurred that should be borne and amortized over the current andsubsequent periods (together with more than one year), including the decoration works of the leased assets, etc.Long-term prepaid expenses are amortized using the straight-line method over the expected periods in whichbenefits are derived.

24. Contract liabilities

A contract liability represents the Group's obligation to transfer goods or services to a customer for which theGroup has received consideration (or an amount of consideration is due) from the customer.

25. Employee benefits

25.1 Accounting treatment of short-term benefits

Actually occurred short-term employee benefits are recognized as liabilities, with a corresponding charge to theprofit or loss for the period or in the costs of relevant assets in the accounting period in which employees provideservices to the Group. Staff welfare expenses incurred by the Group are recognized in profit or loss for the periodor the costs of relevant assets based on the actually occurred amounts when it actually occurred. Non-monetarystaff welfare expenses are measured at fair value.

Payment made by the Group of social security contributions for employees such as premiums or contributions onmedical insurance, work injury insurance and maternity insurance, etc. and payments of housing funds, as wellas trade union fund and employee education fund provided in accordance with relevant requirements, arecalculated according to prescribed bases and percentages in determining the amount of employee benefits andrecognized as relevant liabilities, with a corresponding charge to the profit or loss for the period or the costs ofrelevant assets in the accounting period in which employees provide services.

25.2 Accounting treatment of post-employment benefits

Post-employment benefits are classified into defined contribution plans and defined benefit plans.

During the accounting period of rendering service to employees of the Group, amount which should be paidaccording to defined contribution plans is recognized as liabilities, and recognized in profit or loss or related costsof assets.

NOTES TO THE FINANCIAL STATEMENTFOR THE YEAR ENDED 31 DECEMBER 2024

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

25. Employee benefits - continued

25.2 Accounting treatment of post-employment benefits - continued

For defined benefit plans, the Group calculates defined benefit plan obligations using projected unit credit methodand the service cost resulting from employee service in the current period is recorded in profit or loss or the costof relevant assets. Defined benefit costs are categorized as follows:

? service cost (including current service cost, past service cost, as well as gains and losses on settlements);? net interest of net liabilities or assets of defined benefit plan (including interest income of planned assets,interest expenses of defined benefit plan liabilities and effect of asset ceiling); and? changes arising from re-measurement of net liabilities or net assets of defined benefit plans.

Service costs and net interest of net liabilities and net assets of defined benefit plans are recognized in profit orloss of current period or costs of related assets. Re-measurements of the net defined benefit liability (asset)(including actuarial gains and losses, the return on plan assets, excluding amounts included in net interest on thenet defined benefit liability (asset), and any change in the effect of the asset ceiling, excluding amounts includedin net interest on the net defined benefit liability (asset)) are recognized in other comprehensive income.

Deficit or surplus from present value of obligation of defined benefit plans less fair value of planned asset ofdefined benefit plans are recognized as net liabilities or net assets of a defined benefit plan.

25.3 Accounting treatment of termination benefits

A liability for a termination benefit is recognized in profit or loss for the period at the earlier of when the Groupcannot unilaterally withdraw from the termination plan or the redundancy offer and when the Group recognizesany related restructuring costs or expenses.

26. Provisions

Provisions are recognized when the Group has a present obligation related to a contingency such as productsquality assurance, etc., it is probable that an outflow of economic benefits will be required to settle the obligation,and the amount of the obligation can be measured reliably.

The amount recognized as a provision is the best estimate of the consideration required to settle the presentobligation at the balance sheet date, taking into account factors pertaining to a contingency such as the risks,uncertainties and time value of money. Where the effect of the time value of money is material, the amount of theprovision is determined by discounting the related future cash outflows.

27. Share-based payments

A share-based payment is a transaction which the Group grants equity instruments, or incurs liabilities for amountsthat are determined based on the price of equity instruments, in return for services rendered by employees. TheGroup's share-based payments are equity-settled share-based payments.

27.1 Equity-settled share-based payments

Equity-settled share-based payments granted to employees

Equity-settled share-based payments in exchange for services rendered by employees are measured at the fairvalue of the equity instruments granted to employees at the grant date. Such amount is recognized as related costsor expenses on a straight-line basis over the vesting period, based on the best estimate of the number of equityinstruments expected to vest, with a corresponding increase in capital reserve.

27.1 Equity-settled share-based payments - continued

At each balance sheet date during the vesting period, the Group makes the best estimate according to thesubsequent latest information of change in the number of employees who are granted with options that may vest,etc. and revises the number of equity instruments expected to vest. The effect of the above estimate is recognizedas related costs or expenses, with a corresponding adjustment to capital reserve. When the employee can choosewhether to meet the non-vesting condition but the condition is not met during the vesting period, the Group treatsit as a cancellation of the equity instruments granted.

28. Revenue

28.1 Accounting policies for revenue recognition and measurement disclosed by business types

When (or as) a performance obligation in a contract is satisfied, i.e., when (or as) the customer obtains control ofrelevant goods or services, the Group recognizes as revenue the amount of the transaction price that is allocatedto that performance obligation. A performance obligation is the Group's promise to transfer to a customer a goodor service (or a bundle of goods or services) that is distinct, in a contract with the customer.

The Group assesses a contract at contract inception, identifies each individual performance obligation included inthe contract, and determines whether the performance obligation is satisfied over time or at a point in time. It is aperformance obligation satisfied over time and the Group recognizes revenue over time according to the progressof performance if one of the following conditions is met: (1) the customer simultaneously receives and consumesthe economic benefits provided by the Group's performance as the Group performs; (2) the customer is able tocontrol goods under construction as the Group performs; (3) the goods generated from the Group's performancehave irreplaceable utilization, and the Group is entitled to collect payment for performance completed to datethroughout the contract period. Otherwise, revenue is recognized at a point in time when the customer obtainscontrol over the relevant goods or services. The Group's revenue is mainly derived from the sale of goods, etc.,all of which are performance obligations satisfied at a point in time, and revenue is recognized at the point in timewhen the customer obtains control of the related goods (or services), and the specific accounting policies are setout below:

(1) Sales of goods

The Group sells customers communication products, consumer electronic products, industrial products, cloud andstorage products, automotive electronic products and medical products. Usually, there is only one performanceobligation in the relevant contract or order for selling goods, and the consideration of selling goods is recognizedaccording to the price agreed in the sales contract or order. For domestic sales, the Group recognizes revenue afterthe products are delivered to the carrier designated by the customer, or the products are delivered to the agreeddelivery place according to the agreement or contract and received by the customer and the control of goods istransferred to the customer. For overseas sales, the Group recognizes revenue after the products are delivered tothe carrier designated by the customer, processed with customs clearing procedure for export and loaded on boardthe ship, delivered to the designated delivery place or picked up by the customer from the warehouse respectivelyaccording to the different international trade terms stipulated in the sales contracts or orders and the control ofgoods is transferred to the customer.

The Group provides products quality assurance for the goods sold according to legal regulations and contractualagreements, i.e. assuring the customers that the goods sold comply with the established standards. The Groupaccounts for the quality warranty liabilities in accordance with the Accounting Standard for Business EnterprisesNo. 13 - Contingencies, please refer to Note (III), 26 for details.

The Group determines whether it is a principal or an agent at the time of the transaction based on whether it ownsthe "control" of the goods before the transfer of such goods to the customer. The Group assumes the primaryresponsibility for the transfer of goods to customers, assumes the inventory risk of the goods before the transfer,has the right to determine the price of the traded goods at its own discretion, and assumes the major risks andrewards associated with the ownership of the traded goods during the sales process, therefore, the Group is aprincipal and the revenue shall be recognized based on the total consideration received or receivable.

Where payment is received in advance from customers for the sale of goods, the advance payment received shallbe recorded as a liability and recognized as revenue when the relevant performance obligation is satisfied.

28.1 Accounting policies for revenue recognition and measurement disclosed by business types - continued

(2) Other revenue

Other revenue mainly comes from sales of scrap to customers. Usually, there is only one performance obligation(i.e., delivery of goods) in the relevant contract for sales of products. Relevant revenue is recognized at the timepoint when the control of the relevant products is transferred to the customer. The consideration for the sales ofproducts is determined according to the fixed price agreed in the sales contract.

29. Government grants

Government grants are monetary assets and non-monetary assets from the government to the Group at noconsideration. A government grant is recognized only when the Group can comply with the conditions attachingto the grant and the Group will receive the grant.

If a government grant is in the form of a transfer of a monetary asset, it is measured at the amount received orreceivable. If a government grant is in the form of a non-monetary asset, it is measured at fair value. If the fairvalue cannot be reliably determined, it is measured at a nominal amount. A government grant measured at anominal amount is recognized immediately in profit or loss for the period.

29.1 Determination basis and accounting treatment of government grants related to assets

The Group's government grants, such as the technology reform item for ultra-thin communication module deepintelligent production line, are government grants related to assets, as they are directly related to the investmentand construction of fixed assets. See Notes (VII), 1 for details of the Group's government grants related to assets.

A government grant related to an asset is recognized as deferred income and included in profit or loss over theuseful life of the related asset with the straight-line method.

29.2 Determination basis and accounting treatment of government grants related to income

Government grants other than those related to assets are classified as government grants related to income. SeeNotes (VII), 2 for details of the Group's government grants related to income. The Group classifies governmentgrants that are difficult to be distinguished as government grants related to income aggregately.

For a government grant related to income, if the grant is a compensation for related expenses or losses to beincurred in subsequent periods, the grant is recognized as deferred income over the periods in which the relatedcosts or losses are recognized; If the grant is a compensation for related expenses or losses already incurred, thegrant is recognized immediately in profit or loss.

A government grant related to the Group's daily activities is recognized in other income based on the nature ofeconomic activities; a government grant not related to the Group's daily activities is recognized in non-operatingincome and expenses.

For the repayment of a government grant already recognized, if there is any related deferred income, therepayment is offset against the carrying amount of the deferred income, with any excess recognized in profit orloss for the period.

30. Deferred tax assets/ deferred tax liabilities

The income tax expenses include current income tax and deferred income tax.

30.1 Current income tax

At the balance sheet date, current income tax liabilities (or assets) for the current and prior periods are measuredat the amount expected to be paid (or recovered) according to the requirements of tax laws.

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

30. Deferred tax assets/ deferred tax liabilities - continued

30.2 Deferred tax assets and deferred tax liabilities

For temporary differences between the carrying amounts of certain assets or liabilities and their tax base, orbetween the nil carrying amount of those items that are not recognized as assets or liabilities and their tax basethat can be determined according to tax laws, deferred tax assets and liabilities are recognized using the balancesheet liability method.

Deferred tax is generally recognized for all temporary differences. Deferred tax assets for deductible temporarydifferences are recognized to the extent that it is probable that taxable profits will be available against which thedeductible temporary differences can be utilized. However, for temporary differences associated with the initialrecognition of goodwill and the initial recognition of an asset or liability arising from a transaction (not a businesscombination) that affects neither the accounting profit nor taxable profits (or deductible losses) at the time oftransaction and will not result in taxable temporary differences and deductible temporary differences in equalamounts, no deferred tax asset or liability is recognized.

For deductible losses and tax credits that can be carried forward, deferred tax assets are recognized to the extentthat it is probable that future taxable profits will be available against which the deductible losses and tax creditscan be utilized.

Deferred tax liabilities are recognized for taxable temporary differences associated with investments insubsidiaries and associates, and interests in joint ventures, except where the Group is able to control the timing ofthe reversal of the temporary difference and it is probable that the temporary difference will not reverse in theforeseeable future. Deferred tax assets arising from deductible temporary differences associated with suchinvestments and interests are only recognized to the extent that it is probable that there will be taxable profitsagainst which to utilize the benefits of the temporary differences and they are expected to reverse in theforeseeable future.

At the balance sheet date, deferred tax assets and liabilities are measured at the tax rates, according to tax laws,that are expected to apply in the period in which the asset is realized or the liability is settled.

Current and deferred tax expenses or income are recognized in profit or loss for the period, except when they arisefrom transactions or events that are directly recognized in other comprehensive income or in shareholders' equity,in which case they are recognized in other comprehensive income or in shareholders' equity; and when they arisefrom business combinations, in which case they adjust the carrying amount of goodwill.

At the balance sheet date, the carrying amount of deferred tax assets is reviewed and reduced if it is no longerprobable that sufficient taxable profits will be available in the future to allow the benefit of deferred tax assets tobe utilized. Such reduction in amount is reversed when it becomes probable that sufficient taxable profits will beavailable.

30.3 Income tax offsetting

When the Group has a legal right to settle on a net basis and intends either to settle on a net basis or to realize theassets and settle the liabilities simultaneously, current tax assets and current tax liabilities are offset and presentedon a net basis.

When the Group has a legal right to settle current tax assets and liabilities on a net basis, and deferred tax assetsand deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxableentity or different taxable entities which intend either to settle current tax assets and liabilities on a net basis or torealize the assets and liabilities simultaneously, in each future period in which significant amounts of deferred taxassets or liabilities are expected to be reversed, deferred tax assets and deferred tax liabilities are offset andpresented on a net basis.

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

31. Leases

A lease is a contract whereby the lessor conveys to the lessee in return for a consideration the right to use an assetfor an agreed period of time.

The Group assesses whether a contract is or contains a lease at inception date. Such contract will not be reassessedunless the terms and conditions of the contract are subsequently changed.

31.1 The Group as lessee

31.1.1 Separating components of a lease

If the contract contains one or more lease and non-lease components, the Group will separate the individual leaseand non-lease components and allocate contract consideration according to the relative proportion of the sum ofthe stand-alone prices of the lease components and the stand-alone prices of the non-lease components.

31.1.2 Right-of-use assets

Except for short-term leases and leases of low-value assets, at the commencement date of the lease, the Grouprecognizes a right-of-use assets. The commencement date of the lease is the date on which a lessor makes anunderlying asset available for use by the Group. The Group measures the right-of-use assets at cost. The cost ofthe right-of-use assets comprises:

? the amount of the initial measurement of the lease liabilities;? any lease payments made at or before the commencement date, less any lease incentives received.

The Group depreciates right-of-use assets by reference to the relevant depreciation provisions of the AccountingStandards for Business Enterprises No. 4 - Fixed Assets. The right-of-use assets are depreciated over theremaining useful lives of the leased assets where the Group is reasonably certain to obtain ownership of theunderlying assets at the end of the lease term. Otherwise, right-of-use assets are depreciated over the shorter ofthe lease term and the remaining useful lives of the leased assets.

The Group applies the Accounting Standards for Business Enterprises No. 8 - Impairment of Assets, to determinewhether the right-of-use assets are impaired and perform accounting treatment to identified impairment loss.

31.1.3 Lease liabilities

Except for short-term leases and leases of low-value assets, at the commencement date of the lease, the Groupmeasures the lease liabilities at the present value of the lease payments that are not paid at that date. If the interestrate implicit in the lease cannot be readily determined, the lessee shall use the lessee's incremental borrowing rate.

(III) SIGNIFICANT ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES - continued

31. Leases - continued

31.1 The Group as lessee - continued

31.1.3 Lease liabilities - continued

Lease payments refer to payments relating to the right to use leased assets during the lease term which are madeby the Group to the lessor, including fixed payments and in-substance fixed payments, less any lease incentivesreceivable (if any).

After the commencement date of the lease, the Group calculates interest expenses of lease liabilities for eachperiod of the lease term based on fixed periodic rate, and recognizes such expenses in profit or loss or cost ofrelated assets.

After the commencement date of the lease, if there is a change in the lease term, or in the assessment of an optionto purchase the underlying asset, in which case the related lease liability is remeasured by discounting the revisedlease payments using a revised discount rate at the date of reassessment, the Group re-measures the lease liabilitiesand adjusts the right-of-use assets accordingly. If the book value of the right-of-use asset has been reduced to zero,but the lease liability needs to be reduced further, the Group will recognize the difference in profit or loss for theperiod.

31.1.4 Determination basis and accounting treatment of short-term leases and leases of low-value assets treatedunder a simplified method as lessee

For short-term leases of machinery and equipment and leases of low-value assets to which the recognitionexemption is applied by the Group, right-of-use assets and lease liabilities are not recognized. A short-term leaserefers to a lease that, at the commencement date, has a lease term of 12 months or less and do not contain apurchase option. A lease of low value asset refers to a single lease asset, when new, is no more than USD 5,000.Lease payments on short-term leases and leases of low-value assets are recognized in profit or loss or the cost ofunderlying assets on a straight-line basis over the lease term.

31.1.5 Lease modifications

The Group accounts for a lease modification as a separate lease if:

? the lease modification expanded the scope of the lease by adding the right-of-use of one or more lease assets;and? the increased consideration is equivalent to the amount of stand-alone price of the expanded lease scopeadjusted according to the contract.

If the lease modification is not accounted for as an individual lease, on the effective date of the lease modification,the Group reallocates the consideration of the contract after the change, re-determines the lease term, and re-measures lease liabilities based on the changed lease payments and the present value calculated by the reviseddiscount rate.

If the lease modification results in a reduction in the lease scope or lease term, the carrying amount of the right-of-use assets will be reduced, and the gains or losses relevant to the lease partially of fully terminated will beincluded in profit or loss for the period; for other lease modifications resulting in the re-measurement of leaseliabilities, the carrying amount of right-of-use assets is adjusted accordingly.

31.2 The Group as lessor

31.2.1 Classification criteria and accounting treatment of leases as lessor

Leases are classified as finance leases whenever the terms of the leased assets transfer substantially all the risksand rewards of ownership to the lessee. All other leases are classified as operating leases.

31.2.1.1 The Group as lessor under operating leases

Receipts of lease under operating leases are recognized as rental income on a straight-line basis over the term ofthe relevant lease. Initial direct costs related to operating leases incurred by the Group are capitalized whenincurred, and are recognized in profit or loss for the current period on the same basis as recognition of rentalincome over the lease term.

31.2.2 Subleases

As the lessor of a sublease, the Group accounts for the original lease contract and the sublease contract as twoseparate contracts. The Group classifies the subleases based on the right-of-use assets generating from the originallease rather than the underlying assets of the original lease.

32. Hedge accounting

32.1. Basis for using hedge accounting and accounting treatment method

Certain financial instruments are used as hedging instruments by the Group for the purpose of managing the riskexposure arising from specific risk, such as exchange rate risk, etc. The Group applies hedging accounting for ahedge that satisfies the prescribed conditions. Hedging activities of the Group include hedges of net investmentin foreign operations.

At the inception of hedging, the Group officially designated hedging instruments and hedged items, and preparedwritten documents recording the nature of hedging instruments, hedged items, hedged risks, and hedgeeffectiveness evaluation methods (including the analysis of the causes of invalid hedges and methods to determinethe hedge ratio).

The Group will discontinue hedge accounting when one of the following conditions occurs:

? Due to changes in risk management objectives, the hedging relationship no longer meets the risk

management objectives.? The hedging instrument expires, or is sold, terminated or exercised.? There is no longer an economic relationship between the hedged item and the hedging instruments, or in

the changes of the value arising from the economic relationship between the hedged item and the hedging

instrument, the impact of credit risk begins to dominate.

? The hedging relationship no longer meets other conditions for using the hedge accounting methods.

Hedges for net investment in foreign operations

Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or losson the hedging instrument relating to the effective portion of the hedge is recognized in other comprehensiveincome. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss.

When disposing of all or part of foreign operations, the profits or losses of the above hedging instruments includedin other comprehensive income shall be reclassified in the current profits and losses.

32. Hedge accounting - continued

32.2 Methods of assessing effectiveness of hedges

The Group continuously evaluates whether the hedging relationship meets the requirements of hedgingeffectiveness on and after the inception date of hedging. If the hedging meets the following conditions at the sametime, the Group will determine that the hedging relationship meets the requirements for hedging effectiveness:

? There is an economic relationship between hedged items and hedging instruments.? Among the value changes caused by the economic relationship between hedged items and hedginginstruments, the impact of credit risk does not dominate.

? The hedging ratio of the hedging relationship will be equal to the ratio of the actual number of the Group'shedging items to the actual number of hedging instruments.

If the hedging relationship no longer meets the requirement of hedging effectiveness due to the hedging ratio, butthe risk management objectives of the hedging relationship have not changed, the Group will rebalance thehedging relationship. The number of hedged items or hedging instruments in the hedging relationship is adjustedso that the hedging ratio meets the requirements of hedging effectiveness again.

33. Accounting treatment in relation to the repurchase of equity instruments

The consideration and transaction costs paid to repurchase own equity instruments are deducted from equity. Nogain or loss is recognized in profit or loss on the repurchase, sale or cancellation of the Company's equityinstruments.

34. Critical Judgments in Applying Accounting Policies and Key Assumptions and Uncertainties in Accounting

Estimate

In the application of the Group's accounting policies, which are described in Note (III), the Group is required tomake judgments, estimates and assumptions about the carrying amounts of items in the financial statements thatcannot be measured accurately, due to the internal uncertainty of the operating activities. These judgments,estimates and assumptions are based on historical experiences of the Group's management as well as other factorsthat are considered to be relevant. Actual results may differ from these estimates.

The aforementioned judgments, estimates and assumptions are reviewed regularly on a going concern basis. Theeffect of a change in accounting estimate is recognized in the period of the change, if the change affects that periodonly; or recognized in the period of the change and future periods, if the change affects both.

- Key assumptions and uncertainties in accounting estimates

At the balance sheet date, the key assumptions and uncertainties that are probable to cause significant adjustmentsto the carrying amounts of assets and liabilities in future periods include:

Impairment of accounts receivables

The management considers reasonable and supportable information and makes significant accounting estimatesin assessing the ECL on accounts receivable. The Group estimates the ECL rate of accounts receivable based onfactors such as historical bad debt loss records, customer defaults or delayed payments, and the aging of accountsreceivable, as well as forward-looking information. When considering forward-looking information, the Grouptakes into account the impact of macroeconomic conditions, industry conditions, etc. The amount of ECL willchange according to the Group's estimates and judgments. As of 31 December 2024, the balance of the Group'sprovision for credit losses of accounts receivable was RMB 56,773,852.18 (31 December 2023: RMB43,964,811.88).

Inventories

The Group makes provision for the decline in the value of inventory according to the difference between theinventory costs beyond its net realizable value. The recognition of the net realizable value of inventories requiresthe estimation of the expected sales in the future and the estimation of the costs, expenses and taxes to be incurred.The differences (if any) between the re-estimated value and the current estimate will impact the carrying amountof the inventories over the period in which the estimate is changed. As of 31 December 2024, the balance of theGroup's provision for the decline in the value of inventories was RMB 296,531,721.64 (31 December 2023: RMB331,096,345.17).

Deferred tax assets

The recognition of deferred tax assets requires estimates of taxable income and applicable tax rates for each futureyear. Deferred tax assets are recognized to the extent that it is probable that taxable income will be availableagainst which the deductible temporary differences can be utilized. The timing of the reversal of temporarydifferences and changes in future tax rates would affect income tax expenses (benefits) and the amount of deferredtax recognized. Changes in the Group's estimates of the timing of reversal of temporary differences and the taxrates as well as the judgment on whether it is probable that sufficient taxable income will be timely obtained mayresult in a material adjustment to deferred income taxes. As of 31 December 2024, the Group had recognized thedeferred tax assets of RMB 515,829,271.42 (31 December 2023: RMB 490,796,164.94).

Impairment of goodwill

The Group determines whether goodwill is impaired at least on an annual basis. This requires an estimation ofthe future recoverable amount from the asset groups or set of asset groups to which the goodwill is allocated.Estimating the future recoverable amount requires the Group to make an estimate of the expected future cashflows from the asset groups or set of asset groups and also choose a suitable discount rate in order to calculate thepresent value of those cash flows. When considering the present value of future cash flow, changes in keyassumptions such as revenue growth rate of the projection period, long-term growth rate, profit margin anddiscount rate adopted by the Group may have significant impacts on the present value of the future cash flow usedin impairment testing.

Useful life and estimated net residual value of fixed assets

As disclosed in Note (III) 18, the Group reviews the useful life and estimated net residual value of a fixed assetat least once at each financial year-end. Both scientific and technological innovation and intense competitionwithin the industry significantly impact the estimation of useful life. The Group's management did not findanything that might shorten or extend the useful life of fixed assets of the Group or require changing the estimatednet residual value.

Contents of defined benefit plans and related risks, and its impact over the Group's future cash flows, timing anduncertainty:

UGSI and USI, the Group's subsidiaries, provide retirement benefit plan for full-time regular employees hiredbefore 1 July 2005. The Group acquired FAFG in 2020. FAFG provides retirement benefit plan for its employees,which provides a pension for some employees who have worked for more than 10 years according to the workingyears and certain rate of their salaries in recent 10 years, and a pension for some employees who have worked formore than 2 years according to the working years and certain rate of their salaries in recent 12 months. The Groupacquired Hirschmann in 2023. Hirschmann provides a retirement benefit plan for full-time employees hired before2011.

The defined benefit plans expose the Group to actuarial risks such as discount rate, future salary growth rate, etc.

The Group hired Towers Watson Business Management Consulting Co., Ltd. to estimate the present value ofretirement benefit plan of UGSI and USI by actuary in accordance with the projected unit credit method. Futuresalary growth rate and mortality rate are used to estimate the future cash outflows to recognize the present valueof the plan at a discounted rate which is determined in accordance with the market interest rate of high-qualitycorporate bonds at the balance sheet date. In countries where there is no market for such bonds, the market interestrate for government bonds (at the balance sheet date) shall be used. Since the Group's post-employment benefitobligations remain effective for 9 to 10 years, the discount rate is determined by reference to the bonds with asimilar duration to the post-employment benefit obligations. Therefore, the average interest rate for governmentbonds with a duration of 9 years or more is referenced. The Group recognizes liabilities based on the actuarialresult, with gains or losses arising from actuary recognized in other comprehensive income and not to be reversedto profit or loss in subsequent accounting periods. Past service cost is included in profit or loss for the periodwhen the modification to the plan is made. And net interest is recognized as the amount of net liabilities or assetsof the defined benefit plan multiplying by an appropriate discount rate.

The following table lists the significant actuarial assumptions used by UGSI and USI in determining the presentvalue of the defined benefit plan obligations:

31/12/202431/12/2023
Discount rate1.60%1.40%
Future salary growth rate2.25%2.25%
Mortality rateAssumptions made based on the sixth Mortality Table in TaiwanAssumptions made based on the sixth Mortality Table in Taiwan

As it is unlikely that an assumption can change in an isolated manner due to correlations among certainassumptions, the sensitivity analysis above may not reflect actual changes in present value of defined benefitplans.

In sensitivity analysis above, the method used to calculate net liabilities of defined benefit plans at the end of theperiod is the same with that used to recognize related liabilities in balance sheet.

Compared with previous years, methods and assumptions adopted to analyze sensitivity remain unchanged.

(VIII) RISKS ASSOCIATED WITH FINANCIAL INSTRUMENTS - continued

The Group adopts sensitivity analysis technique to analyze how the profit and loss for the period and shareholders'equity would have been affected by reasonably possible changes in the relevant risk variables. As it is unlikelythat risk variables will change in an isolated manner, and the interdependence among risk variables will havesignificant effect on the amount ultimately influenced by the changes in a single risk variable, the following arebased on the assumption that the change in each risk variable is on a stand-alone basis.

1. Risk management objectives and policies

The Group's risk management objectives are to achieve a proper balance between risks and yield, minimize theadverse impacts of risks on the Group's operation performance, and maximize the benefits of the shareholders andother stakeholders. Based on these risk management objectives, the Group's basic risk management strategy is toidentify and analyze the Group's exposure to various risks, establish an appropriate maximum tolerance to risk,implement risk management, and monitors regularly and effectively these exposures to ensure the risks aremonitored at a certain level.

1.1 Market risk

The Group closely monitors the effects of changes in the foreign exchange rates on the Group's currency riskexposures, and uses foreign currency forward contracts to reduce part of the currency exposures.

Sensitivity analysis on currency risk

On the basis of the assumption that all hedges of net investments in foreign operations are highly effective, whereall other variables are held constant, reasonably possible changes in the foreign exchange rate may have thefollowing pre-tax effect on the profit or loss for the year and shareholders' equity:

(VIII) RISKS ASSOCIATED WITH FINANCIAL INSTRUMENTS - continued

1. Risk management objectives and policies - continued

1.1 Market risk - continued

1.1.2. Interest rate risk - risk of changes in cash flows

The Group's cash flow interest rate risk of financial instruments relates primarily to variable-rate bank borrowings(see Note (V) 24 for details). The Group closely monitors the effects of changes in the interest rates on the Group'sinterest rate risk exposures. It is the Group's policy to keep its borrowings at floating rate of interests with no otherarrangements such as interest rate swaps.

Sensitivity analysis on interest rate risk

Where all other variables are held constant, reasonably possible changes in the interest rate may have the followingpre-tax effect on the profit or loss for the year and shareholders' equity:

Unit: RMB’000

Financial instruments at floating interest rate1% depreciation13,71213,71216,62316,623

1.1.3. Other price risk

The price risk of the group mainly arises from trading equity instrument investment and other equity instrumentinvestment. The group reduces the price risk of equity instrument investment by holding a variety of equitysecurities portfolio. As at the end of the period, the Group's investments in equity instruments held by the Groupincluded listed companies, therefore, the Group is directly or indirectly exposed to the risk of fluctuations inmarket prices of securities. If the market prices of the securities of the Group's investments in equity instrumentsheld directly and indirectly by the Group at the end of the year had increased or decreased by 5% while all othervariables remained unchanged, the Group's shareholders' equity and profit or loss at the end of the year wouldhave been increased or decreased by RMB1,138,489.78 (without taking into account of the effect of income tax)(2023: RMB1,946,761.88).

1.2 Credit risk

As at 31 December 2024, the Group's maximum exposure to credit risk which will cause a financial loss to theGroup due to failure to discharge an obligation by the counterparties is arising from: cash and bank balances (Note(V). 1), held-for-trading financial assets (Note (V). 2), notes receivable (Note (V). 3), accounts receivable (Note(V). 4), other receivables (Note (V). 6), non-current assets due within one year (Note (V). 8), long-termreceivables (Note (V). 10), other non-current assets (Note (V). 22) and non-current financial assets at FVTPL thatare not included in the impairment assessment (Note (V). 13). As at the balance sheet date, the carrying amountof the Group's financial assets is its maximum exposure to credit risk.

In order to minimize the credit risk, the Group has delegated a team responsible for determination of credit limits,credit approvals and other monitoring procedures to ensure that follow-up action is taken to recover overdue debts.In addition, the Group reviews the recoverable amount of financial assets at each balance sheet date to ensure thatadequate provision for credit loss is made for relevant financial assets. In this regard, the management of theGroup considers that the Group's credit risk is significantly reduced.

NOTES TO THE FINANCIAL STATEMENTSFOR THE YEAR ENDED 31 DECEMBER 2024

(VIII) RISKS ASSOCIATED WITH FINANCIAL INSTRUMENTS - continued

1. Risk management objectives and policies - continued

1.2 Credit risk - continued

The credit risk on cash and bank balances is limited because they are deposited with banks with high credit ratings.

As of 31 December 2024, the balance of bank acceptance bills held by the Group was RMB 79,450,682.42, ofwhich all accepting banks were banks with high credit rating. Therefore, the management of the Group believesthat the credit risk of relevant bank acceptance bills is low.

As at 31 December 2024, the balance of accounts receivable of the Group's top 5 customers was RMB5,475,109,550.83 (31 December 2023: RMB 5,084,392,042.35), accounting for 53.09% (31 December 2023:

50.50%) of the Group's accounts receivable. Except for that, the Group has no other significant credit riskexposures concentrated on a single financial asset or a portfolio of financial assets with similar characteristics.

1.3. Liquidity risk

In the management of the liquidity risk, the Group monitors and maintains a level of cash and cash equivalentsdeemed adequate by the management to finance the Group's operations and mitigate the effects of fluctuations incash flows. The management monitors the utilization of bank borrowings and ensures compliance with loancovenants.

The following is the maturity analysis for liabilities held by the Group which is based on undiscounted remainingcontractual obligations:
