Basis of preparation and accounting policies	2. Basis of preparation and accounting policies 2.1 Basis of preparation The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The consolidated financial statements have been prepared on a historical cost basis except as disclosed in the accounting policies below. The consolidated financial statements are presented in Renminbi (“RMB”) and all values are rounded to the nearest thousand (“RMB’000”), except when otherwise indicated. Translation of amounts from Renminbi to the United States Dollar (“US Dollar”) is solely for the convenience of the reader. Translation of amounts from Renminbi to US Dollar has been made at the rate of RMB 6.9519 = US$ 1.00, the rate quoted by the People’s Bank of China at the close of business on February 28, 2023 and all values are rounded to the nearest thousand (“US$’000”), except when otherwise indicated. The consolidated financial statements provide comparative information in respect of the previous period. 2.2 Basis of consolidation The consolidated financial statements comprise the financial statements of the Company and its subsidiaries as of December 31, 2022. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Group controls an investee if and only if the Group has: • Power over the investee (i.e. existing rights that give it the current ability to direct the relevant activities of the investee) • Exposure, or rights, to variable returns from its involvement with the investee • The ability to use its power over the investee to affect its returns Generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including: • The contractual arrangement with the other vote holders of the investee • Rights arising from other contractual arrangements • The Group’s voting rights and potential voting rights The Group re-assesses Profit or loss and each component of other comprehensive income (“OCI”) are attributed to the equity holders of the Company of the Group and to the non-controlling non-controlling A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction. If the Group loses control over a subsidiary, it derecognizes the related assets (including goodwill), liabilities, non-controlling 2.3 Summary of significant accounting policies (a) Business combinations and goodwill Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, which is measured at acquisition date fair value and the amount of any non-controlling non-controlling The Group determines that it has acquired a business when the acquired set of activities and assets include an input and a substantive process that together significantly contribute to the ability to create outputs. The acquired process is considered substantive if it is critical to the ability to continue producing outputs, and the inputs acquired include an organized workforce with the necessary skills, knowledge, or experience to perform that process or it significantly contributes to the ability to continue producing outputs and is considered unique or scarce or cannot be replaced without significant cost, effort, or delay in the ability to continue producing outputs. When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as of the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree. Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Contingent consideration classified as equity is not re-measured Financial Instruments Goodwill is initially measured at cost (being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling re-assesses After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group’s cash-generating units that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Where goodwill has been allocated to a cash-generating unit (“CGU”) and part of the operation within that unit is disposed of, the goodwill associated with the disposed operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed in these circumstances is measured based on the relative values of the disposed operation and the portion of the cash-generating unit retained. Where the Group had granted put option to third party investors (non-controlling interests) for their investments in subsidiaries, the Group recognized a financial liability based on the present value of the amount payable upon exercise of the put. A corresponding amount to equity attributable to the parent (capital reserves) will be recognized. (b) Investments in associates and joint ventures An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but is not control or joint control over those policies. A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control. The considerations made in determining significant influence or joint control are similar to those necessary to determine control over subsidiaries. The Group’s investments in its associates and joint ventures are accounted for using the equity method. Under the equity method, the investment in an associate or a joint venture is initially recognized at cost. The carrying amount of the investment is adjusted to recognize changes in the Group’s share of net assets of the associate or joint venture since the acquisition date. Goodwill relating to the associate or joint venture is included in the carrying amount of the investment and is not tested for impairment separately. The statement of profit or loss reflects the Group’s share of the results of operations of the associate or joint venture. Any change in OCI of those investees is presented as part of the Group’s OCI. In addition, when there has been a change recognized directly in the equity of the associate or joint venture, the Group recognizes its share of any changes, when applicable, in the statement of changes in equity. Unrealized gains and losses resulting from transactions between the Group and the associate or joint venture are eliminated to the extent of the interest in the associate or joint venture. The aggregate of the Group’s share of profit or loss of an associate and a joint venture is shown on the face of the statement of profit or loss outside operating profit and represents profit or loss after tax and non-controlling The financial statements of the associate or joint venture are prepared for the same reporting period as the Group. When necessary, adjustments are made to bring the accounting policies in line with those of the Group. After application of the equity method, the Group determines whether it is necessary to recognize an impairment loss on its investment in its associate or joint venture. At each reporting date, the Group determines whether there is objective evidence that the investment in the associate or joint venture is impaired. If there is such evidence, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate or joint venture and its carrying value, then recognizes the loss within “Share of profit/(loss) of associates and joint ventures, net of tax” in the statement of profit or loss. Upon loss of significant influence over the associate or joint control over the joint venture, the Group measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and proceeds from disposal is recognized in profit or loss. (c) Current versus non-current The Group presents assets and liabilities in the statement of financial position based on current/non-current • Expected to be realized or intended to be sold or consumed in normal operating cycle; • Held primarily for the purpose of trading; • Expected to be realized within twelve months after the reporting period; or • Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period. All other assets are classified as non-current. A liability is current when: • It is expected to be settled in normal operating cycle; • It is held primarily for the purpose of trading; • It is due to be settled within twelve months after the reporting period; or • There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period. The terms of the liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification. The Group classifies all other liabilities as non-current. Deferred tax assets and liabilities are classified as non-current (d) Fair value measurement The Group measures financial instruments, such as quoted equity securities and bills receivable and a foreign exchange forward contract, at fair value at each balance sheet date. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either: • In the principal market for the asset or liability, or • In the absence of a principal market, in the most advantageous market for the asset or liability The principal or the most advantageous market must be accessible by the Group. The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest. A fair value measurement of a non-financial The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole: • Level 1 – Quoted (unadjusted) market prices in active markets for identical assets or liabilities • Level 2 – Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable • Level 3 – Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable For assets and liabilities that are recognized in the financial statements at fair value on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above. Fair value related disclosures for financial instruments that are measured at fair value are summarized in the following notes: • Quoted equity securities Note 34 • Bills receivable Note 34 • Foreign exchange forward contract Note 34 (e) Foreign currency translation The Company’s functional currency is US Dollar. The Group’s consolidated financial statements are presented in Renminbi, which is also the functional currency of Yuchai, the largest operating segment of the Group. Each entity in the Group determines its own functional currency, and items included in the financial statements of each entity are measured using that functional currency. Transactions and balances Transactions in foreign currencies are initially recorded by the Group’s entities at their respective functional currency spot rates at the date the transaction first qualifies for recognition. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rate of exchange at the reporting date. Differences arising on settlement or translation of monetary items are recognized in profit or loss with the exception of monetary items that are designated as part of the hedge of the Group’s net investment of a foreign operation. These are recognized in OCI until the net investment is disposed of, at which time, the cumulative amount is reclassified to profit or loss. Tax charges and credits attributable to exchange differences on those monetary items are also recorded in OCI. Non-monetary Non-monetary non-monetary In determining the spot exchange rate to use on initial recognition of the related asset, expense or income (or part of it) on the de-recognition non-monetary non-monetary non-monetary non-monetary Group companies On consolidation, the assets and liabilities of foreign operations are translated into RMB at the rate of exchange prevailing at the reporting date and their statements of profit or loss are translated at average exchange rates during the reporting period. The exchange differences arising on translation for consolidation are recognized in OCI. On disposal of a foreign operation, the component of OCI relating to that particular foreign operation is reclassified to profit or loss. Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition are treated as assets and liabilities of the foreign operation and translated at the spot rate of exchange at the reporting date. (f) Revenue from Contracts with Customers Revenue from contracts with customers is recognized when control of the goods or services are transferred to the customer at an amount that reflects the consideration to which the Group expects to be entitled in exchange for those goods or services. The Group has generally concluded that it is the principal in its revenue arrangements because it typically controls the goods or services before transferring them to the customer. The disclosures of significant accounting judgements, estimates and assumptions relating to revenue from contracts with customers are provided in Note 3. Sale of engines Revenue from sale of engines is recognized at the point in time when control of the engine is transferred to the customer, generally on delivery of the engines, or, in some cases, when the engines are installed by the customers. The Group considers whether there are other promises in the contract that are separate performance obligations to which a portion of the transaction price needs to be allocated (e.g. warranties). In determining the transaction price for the sale of engines, the Group considers the effects of variable consideration and the existence of significant financing components. (i) Variable consideration If the consideration in a contract includes a variable amount, the Group estimates the amount of consideration to which it will be entitled in exchange for transferring the goods to the customer. The variable consideration is estimated at contract inception. Some contracts for the sale of engines provide customers with sales rebates based on the sales volume. The sales rebates give rise to variable consideration. Sales rebates The Group enters into contractual arrangements to provide certain customers with sales rebates when the quantity of products purchased during the period exceeds a threshold specified in the contract. Based on contractual arrangement with the customers, the sales rebates are netted against “Trade receivables”. If the receivables had been settled by the customers, amounts in excess of “Trade receivables” will be recognized as refund liabilities in “Trade and other payables”. Sales Returns The Group does not extend its sales returns policy to all customers. However the Group allows for certain returns, only on a case-by-case (ii) Significant financing component The Group receives advance payments from customers for the sale of engines. The Group applies the practical expedient for short-term advances received from customers. That is, the promised amount of consideration is not adjusted for the effects of a significant financing component if the period between the transfer of the promised good or service and the payment is one year or less. Warranty obligations The Group typically provides warranties for general repairs of defects as part of the sale of engines. These assurance-type warranties are accounted for as warranty provisions. Refer to the accounting policy on warranty provisions in Section (s) Provisions Certain contracts provide a customer with maintenance service, i.e. a distinct service to the customer in addition to the assurance that the product complies with agreed upon specification. These service-type warranties are bundled together with the sale of engines. Contracts for bundled sale of engines and a service-type warranty comprise two performance obligations because the promises to transfer the engines and to provide the service-type warranty are capable of being distinct. Using a combination of expected cost-plus margin and residual approaches, the transaction price is allocated to the service-type warranty and engines with the former performance obligation recognizing a corresponding contract liability. Revenue for service-type warranties is recognized at the point in time when the service-type warranty is provided. Sale of completed development properties Revenue is recognized when control of the property has been transferred to the customer, either over time or at a point in time, depending on the contractual terms and the practices in the legal jurisdictions. For development properties whereby the Group is restricted contractually from directing the properties for another use as they are being developed and has an enforceable right to payment for performance completed to date, revenue is recognized over time, based on the construction and other costs incurred to-date For development properties whereby the Group does not have an enforceable right to payment for performance completed to date, revenue is recognized when the customer obtains control of the asset. Rendering of services Revenue from rendering services relates to project management contracts, and hotel room and restaurant operations. Revenue is recognized over the period in which the services are rendered, by reference to completion of the specific transaction assessed on the basis of the actual service provided as a proportion of the total services to be performed. Contract balances Trade receivables A receivable is recognized if an amount of consideration that is unconditional is due from the customer (i.e. only the passage of time is required before payment of the consideration is due). Refer to accounting policies of financial assets in Section (m) Financial instruments – Initial recognition and subsequent measurement Contract liabilities A contract liability is recognized if a payment is received or a payment is due (whichever is earlier) from a customer before the Group transfers the related goods or services. Contract liabilities are recognized as revenue when the Group performs under the contract (i.e., transfers control of the related goods or services to the customer). Right of return assets A right-of-return Refund liabilities A refund liability is recognized for the obligation to refund some or all of the consideration received (or receivable) from a customer. The Group’s refund liabilities arise from customers’ right of return and sales rebates. Based on contractual arrangement with the customers, sales rebates are netted against “Trade receivables”. If the receivables had been settled by the customers, amounts in excess of “Trade receivables” will be recognized as refund liabilities. Refund liabilities arising from contractual sales returns is measured at the amount the Group ultimately expects it will have to return to the customer. The Group updates its estimates of refund liabilities arising from sales returns at the end of each reporting period. Costs to fulfil a contract Costs to fulfil a contract are capitalized if the costs relate directly to the contract, generate or enhance resources used in satisfying the contract and are expected to be recovered. Other contract costs are expensed as incurred. Capitalized contract costs are subsequently recognized in profit or loss as the Group recognizes the related revenue. An impairment loss is recognized in profit or loss to the extent that the carrying amount of the capitalized contract costs exceeds the remaining amount of consideration that the Group expects to receive in exchange for the goods or services to which the contract costs relates less the costs that relate directly to providing the goods and that have not been recognized as expenses. (g) Government grants Government grants are recognized where there is reasonable assurance that the grant will be received and all attached conditions will be complied with. When the grant relates to an expense item, it is recognized as income on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. When the grant relates to an asset, it is recognized as income in equal amounts over the expected useful life of the related asset. (h) Taxes Current income tax Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the reporting date in the countries where the Group operates and generates taxable income. Current income tax relating to items recognized directly in equity is recognized in equity and not in the statement of profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate. Deferred tax Deferred tax is provided using the liability method on temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date. Deferred tax liabilities are recognized for all taxable temporary differences, except: • When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss • In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future Deferred tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences and the carry forward of unused tax credits and unused tax losses can be utilized, except: • When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss • In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date. Deferred tax relating to items recognized outside profit or loss is recognized outside profit or loss. Deferred tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Tax benefits acquired as part of a business combination, but not satisfying the criteria for separate recognition at that date, are recognized subsequently if new information about facts and circumstances change. The adjustment is either treated as a reduction to goodwill (as long as it does not exceed goodwill) if it was incurred during the measurement period or recognized in profit or loss. The Group offsets deferred tax assets and deferred tax liabilities if and only if it has a legally enforceable right to set off current tax assets and current tax liabilities and the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered. Sales tax Expenses and assets are recognized net of the amount of sales tax, except: • When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item, as applicable • When receivables and payables are stated with the amount of sales tax included The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the statement of financial position. (i) Cash dividend and non-cash The Company recognizes a liability to make cash or non-cash Non-cash Upon distribution of non-cash (j) Property, plant and equipment Construction in progress is stated at cost, net of accumulated impairment losses, if any. Property, plant and equipment are stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. Such cost includes the cost of replacing part of the property, plant and equipment and borrowing costs for long-term construction projects if the recognition criteria are met. When significant parts of property, plant and equipment are required to be replaced at intervals, the Group depreciates them separately based on their specific useful lives. Likewise, when a major inspection is performed, its cost is recognized in the carrying amount of the plant and equipment as a replacement if the recognition criteria are satisfied. All other repair and maintenance costs are recognized in profit or loss as incurred. Freehold land has an unlimited useful life and therefore is not depreciated. Asset under construction included in property, plant and equipment are not depreciated as these assets are not yet ready for intended use. Depreciation is calculated on a straight-line basis over the estimated useful life of the assets as follows: Freehold buildings : 50 years Leasehold buildings and improvements : 50 years or period of lease, whichever is shorter Plant, machinery and equipment : 2 to 20 years Office furniture, fittings and equipment : 2 to 20 years Motor and transport vehicles : 4 to 11 years An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on de-recognition The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate. The Group capitalizes interest with respect to major assets under installation or construction based on the weighted average cost of the Group’s general borrowings and actual interest incurred for specific borrowings. Repairs and maintenance of a routine nature are expensed while those that extend the life of assets are capitalized. Construction in progress represents factories under construction and machinery and equipment pending installation. All direct costs relating to the acquisition or construction of buildings and machinery and equipment, including interest charges on borrowings, are capitalized as construction in progress. (k) Investment properties Investment properties are properties owned by the Group that are held to lease to third parties and earn rentals rather than for use in the production or supply of goods or services, or for administrative purposes, or in the ordinary course of business. Investment properties comprise completed investment properties and properties that are being constructed or developed for future use as investment properties. Investment properties are initially recognized at cost, including transaction costs. Subsequent to initial recognition, investment properties are carried at cost less accumulated depreciation and impairment losses. Depreciation is recognized in profit or loss on a straight-line basis over the estimated useful lives of the investment properties. The estimated useful life is 30 years. Depreciation methods, useful lives and residual values of investment properties are reassessed at each reporting date. Investment properties are derecognized either when they have been disposed of (i.e., at the date recipient obtains control) or when they are permanently withdrawn from use and no future economic benefit is expected from its disposal. The difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period of de-recognition. de-recognition non-cash Transfers are made to (or from) investment property only when there is a change in use. Under cost model, the transfer does not change the carrying amount of the property transferred. (l) Intangible assets Intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Internally generated intangibles, excluding capitalized development costs, are not capitalized and the related expe

Significant accounting judgments, estimates and assumptions	3. Significant accounting judgments, estimates and assumptions The preparation of the Group’s consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, the accompanying disclosures, and the disclosure of contingent liabilities. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods. Other disclosures relating to the Group’s exposure to risks and uncertainties includes: • Capital management (Note 33) • Financial risk management objectives and policies (Note 32) • Sensitivity analyses disclosures (Note 12 and 32) 3.1 Judgments In the process of applying the Group’s accounting policies, management has made the following judgments, which have the most significant effect on the amounts recognized in the consolidated financial statements: Revenue from Contracts with Customers The Group applied the following judgments that significantly affect the determination of the amount and timing of revenue from contracts with customers: • Identifying contract price and performance obligations in sales of engines The Group provides certain warranties for both general repairs and maintenance service as part of the sales of engines. For general repairs, such warranties will be assurance-type warranty that will continue to be accounted for under IAS 37 Provisions, Contingent Liabilities and Contingent Assets on-road Derecognition of bills receivable The Group sell certain bills receivable to banks on an ongoing basis depending on funding needs and money market conditions. The Group also endorse certain bills to suppliers for debts settlement. Chinese law governing bills allows recourse to be traced to all the parties in the discounting and endorsing process. In relation to the derecognition of bills receivable when discounted and endorsed, the management assess the credit rating of the banks that issued these bills, consider the designated commercial banks by China regulatory are high credit rating and believe that the contractual right to receive the cash flows from the asset have terminated with the Group, but transferred to the banks and suppliers. Accordingly, the respective bills receivables were derecognized, and a discount equal to the difference between the carrying value of the bills receivable and cash received is recorded in the statement of profit or loss. Please refer to Note 15. Deferred tax assets Deferred tax assets are recognized for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized. Significant management judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable profits. The carrying amounts of deferred tax assets as of December 31, 2021 and 2022 are RMB million and RMB million (US$ million) respectively. The deferred tax assets of the Group primarily relate to unutilized tax losses, unutilized capital allowances and investment allowances, as well as other unrecognized temporary differences relating to asset impairment and deferred grants. If the Group was able to recognize all unrecognized deferred tax assets, profit would increase by RMB million (US$ million) for year ended December 31, 2022 (2021: RMB million). Development costs Development costs are capitalized in accordance with the accounting policy in Note 2.3 (l). Capitalization of development costs requires the application of management judgment to determine, what continues to constitute development activities and when a development project should cease further capitalization of development costs. Management judgment is also required to ascertain the nature of expenses that qualify for capitalization. 3.2 Estimates and assumptions The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Group based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising that are beyond the control of the Group. Such changes are reflected in the assumptions when they occur. Impairment of non-financial Impairment exists when the carrying value of an asset or cash-generating unit exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arm’s length, for similar assets or observable market prices less incremental costs for disposing of the asset. The value in use calculation is based on a discounted cash flow (“DCF”) model. The cash flows are derived from the forecasts for the next seven

Earnings per share	9. Earnings per share Basic earnings per share is calculated by dividing the profit for the year attributable to equity holders of the Company by the weighted average number of ordinary shares outstanding during the year. Diluted earnings per share is calculated by dividing the profit attributable to equity holders of the Company by the weighted average number of ordinary shares outstanding during the year plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares. Basic earnings per share The calculation of basic earnings per share is based on: 31.12.2020 31.12.2021 31.12.2022 31.12.2022 RMB’000 RMB’000 RMB’000 US$’000 Profit attributable to equity holders of the Company 548,903 272,673 218,581 31,442 Weighted average number of ordinary shares 40,858,290 40,858,290 40,858,290 40,858,290 Diluted earnings per share The weighted average number of ordinary shares adjusted for the effect of unissued ordinary shares under the Share Option Scheme is determined as follows: 31.12.2020 31.12.2021 31.12.2022 Weighted average number of shares issued, used in the calculation of basic earnings per share 40,858,290 40,858,290 40,858,290 Diluted effect of share options — — — Weighted average number of ordinary shares adjusted for effect of dilution 40,858,290 40,858,290 40,858,290 In 2022, 270,000 (2021: 270,000; 2020: 470,000) share options granted to employees under the existing employee share option plan have not been included in the calculation of diluted earnings per share because they are anti-dilutive.

Goodwill acquired through business combinations have been allocated to two cash-generating units for impairment testing as follows: • Yuchai • Yulin Hotel. Goodwill allocated to Yulin Hotel was fully impaired in 2008. Carrying amount of goodwill allocated to the cash-generating unit: 31.12.2021 31.12.2022 31.12.2022 RMB’000 RMB’000 US$’000 Yuchai 212,636 212,636 30,587 Yuchai unit The Group performs its impairment test annually. The recoverable amount of the unit was determined based on a value in use calculation using cash flow projections from financial budgets approved by senior management covering a ten-year period. The business of Yuchai is stable since the Group has control in 1994 and the business model of Yuchai is unlikely to change in the foreseeable future. The pre-tax discount rate applied to the cash flow projections w as 14.34% ( 2021: %) and cash flows beyond the ten-year period are extrapolated using a 5 % growth rate (2021: %) that is the same as the long-term Key assumptions used for value in use calculations Key assumptions used in estimation of value in use were as follows: • Profit from operation • Discount rate Profit from operation – Profit from operation is based on management’s estimate with reference to historical performance and future business outlook of Yuchai unit. Discount rate – Discount rate reflects management’s estimate of the risks specific to the cash-generating unit and is estimated based on weighted average cost of capital (“WACC”). The WACC takes into account both debt and equity. The cost of equity is derived from the expected return on investment by the Group’s investors. The cost of debt is based on the interest-bearing borrowings the cash-generating unit is obliged to service. This rate is weighted according to the optimal debt/equity structure arrived on the basis of the capitalization structure of the peer group. Sensitivity to changes in assumptions The implications of the key assumptions for the recoverable amount are discussed below: Profit from operation – A decreased demand can lead to a decline in profit from operation. A decrease in demand by 26.64% (2021: 15.21%) would result in impairment. Discount rate – A rise in pre-tax 17.92% (2021: 14.03%) in the Yuchai unit would result in impairment. With regard to the assessment of value in use of the Yuchai unit, management believes that no reasonably possible change in any of the above key assumptions would cause the recoverable amount to materially fall below the carrying value of the unit. Technology know-how At December 31, 2022, The Group has an intangible asset representing technology development costs with carrying amount of RMB million, which is the technology know-how that relates to production of 4Y20 engines. As of December 31, 2022, the accumulated impairment loss that was brought forward from prior years on this technology know-how was RMB million. In late 2018, the Group had commenced the production of 4Y20 engines. In 2020, 2021 and 2022, management believed that there was no indicator for further impairment. Also, having considered that there was no significant change to the market and economic environment which will have a favorable effect to the recoverable amount of the intangible asset, management had concluded that no reversal of impairment was necessary in 2020, 2021 and 2022. In 2022, the development of certain engine platform relating to National VI engines were completed, and the related development costs amounting to RMB 121.2 million (US$ 17.4 million) (2021: RMB 414.7 million) were transferred from development costs to technology know-how, and amortization were charged accordingly based on the Group’s policy. Development costs During 2021 and 2022, the Group has capitalized development costs of RMB million and RM B million million), respectively, mainly million (US$ million) (2021: RMB Million). These development costs relate to on-going development efforts and, accordingly, have not yet been available for use, and therefore no amortization charges were recorded. In 2021 and 2022, the Group performs an impairment test on the development costs that are not available for use. No impairment has been identified. The recoverable amount was determined based on its value in use using the discounted cash flow approach. Cash flows were projected based on historical growth, past experience and management best estimation of future business outlook. In 2022, the Group used 7 years (2021: 8 years) forecast and were based on the updated financial budgets approved by the senior management with no terminal value. Key assumptions used in estimation of value in use were as follows: • Profit from operation – Profit from operation is based on management’s estimate with reference to historical revenue generated, growth rate and estimation of future business outlook. In 2022, the Group used a 7 years business plan, and estimated the revenue growth rate is the range of 15% to year-on-year from 2023 to 2027 in view of the implementation of new emission standard and management expect an accelerated growth for new energy products due to the government’s emphasis on new energy. Management assumes the revenue for the year 2028 and 2029 remain the same level as 2027. In 2021, the Group used a 8 years business plan, the revenue growth rate is estimated at an average around 12% year-on-year from 2022 to 2025 decrease • Discount rate – Discount rate reflects management’s estimate of the risks specific to the cash-generating unit and is estimated based on weighted average cost of capital (“WACC”). The WACC takes into account both debt and equity. The cost of equity is derived from the expected return on investment by the Group’s investors. The cost of debt is based on the interest-bearing borrowings the cash-generating unit is obliged to service. This rate is weighted according to the optimal debt/equity structure arrived on the basis of the capitalization structure of the peer group. The Group has applied a pre-tax 14.34% Sensitivity to changes in assumptions The implications of the key assumptions for the recoverable amount are discussed below: Profit from operation – A decreased demand can lead to a decline in profit from operation. A decrease in demand by 4.88% (2021: 13.86%) would result in impairment. Discount rate – A rise in pre-tax 19.17% (2021: 15.69%) would result in impairment. With regard to the assessment of value in use, management believes that no reasonably possible change in any of the above key assumptions would cause the recoverable amount to materially fall below the carrying value. Trademarks In 2019, Yuchai entered into a trademark license agreement with GY Group under which Yuchai was granted the exclusive and perpetual use of the trademarks listed in the trademark license agreement for a one-time (US$ 24.4 million). Management has assessed and concluded that the right granted by the trademark license, according to the terms and conditions of the trademark license agreement, is indefinite. In 2021 and 2022, the Group performed an annual impairment review by taking Yuchai as a cash-generating unit. Using the same cash flow projection and assumptions for goodwill impairment test disclosed above, management concluded that no impairment charge is to be recognized in 2021 and 2022.

All options granted under the Equity Plan are subject to a vesting schedule as follows: (1) one year after the date of grant for up to 33% of the shares over which the options are exercisable; (2) two years after the date of grant for up to 66% (including (1) above) of the shares over which the options are exercisable; and (3) three years after the date of grant for up to 100% (including (1) and (2) above) of the shares over which the options are exercisable. In 2022, there was no expense arising from equity-settled share-based payment transactions. (2020: Nil; 2021: Nil). Movements during the year The following table illustrates the number and weighted average exercise prices (“WAEP”) of, and movements in share options during the year: Number of share options WAEP Number of share options WAEP 31.12.2021 31.12.2021 31.12.2022 31.12.2022 Outstanding at January 1 470,000 US$ 21.11 270,000 US$ 21.11 Cancelled during the year (200,000 ) US$ 21.11 — US$ 21.11 Outstanding at December 31 270,000 US$ 21.11 270,000 US$ 21.11 Exercisable at December 31 270,000 US$ 21.11 270,000 US$ 21.11 The fair value of services received in return for share options granted are measured by reference to the fair value of share options granted. The estimate of the fair value of the services received is measured based on the Black-Scholes model. The expected life used in the model has been adjusted, based on management’s best estimate, for the effects of non-transferability, Fair value of share options and assumptions Date of grant of options On July 29, 2014 Fair value at measurement date (US$) 5.70 – 6.74 Share price (US$) 21.11 Exercise price (US$) 21.11 Expected volatility (%) 47.4 Expected option life (years) 3.5 – 5.5 Expected dividends (%) 5.81 Risk-free interest rate (%) 1.4 – 2.0 The exercise price for options outstanding as of December 31, 2022 was US$21.11 dollar (2021: US$21.11 dollar). The weighted average remaining contractual life for the share options outstanding as of December 31, 2022 was 1.6 (2021: 2.6) years. The expected volatility reflects the assumption that the historical volatility over a period similar to the life of the options is indicative of future trends, which may not necessarily be the actual outcome.

Financial risk management objectives and policies	32. Financial risk management objectives and policies The Group’s principal financial liabilities comprise loans and borrowings, trade and other payables and other financial liability arising from a put option to a non-controlling interest. The main purpose of these financial liabilities is to finance the Group’s operations. The Group has trade and other receivables, and cash and bank deposits that derive directly from its operations. The Group also holds quoted equity securities. The Group is exposed to market risk, credit risk and liquidity risk. The Group’s senior management oversees the management of these risks. There has been no change to the Group’s exposure to these financial risks or the manner in which it manages and measures the risks. Market risk Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risk comprise three types of risk: interest rate risk, currency risk and other price risk, such as equity price risk. Financial instruments affected by market risk include loans and borrowings, deposits, quoted equity securities and derivative financial instrument. The sensitivity analyses in the following sections relate to the position as of December 31, 2021 and 2022. The sensitivity analyses have been prepared on the basis that the amount of net debt, the ratio of fixed to floating interest rates of the debt and the proportion of financial instruments in foreign currencies are all constant at December 31, 2022. The analyses exclude the impact of movements in market variables on provisions and on the non-financial Interest rate risk Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Group’s exposure to the risk of changes in market interest rates relates primarily to the Group’s interest-bearing bank deposits and loans and borrowings from banks and financial institutions. The interest-bearing loans and borrowings of the Group are disclosed in Note 26. As certain interest rates are based on interbank offer rates, the Group is exposed to cash flow interest rate risk. This risk is not hedged. Interest-bearing bank deposits are short to medium-term in nature but given the significant cash and bank balances held by the Group, any variation in the interest rates may have a material impact on the results of the Group. The Group manages its interest rate risk by having a mixture of fixed and variable rates for its deposits and borrowings. Interest rate sensitivity The sensitivity analyses below have been determined based on the exposure to interest rates for bank deposits and interest-bearing financial liabilities at the end of the reporting period and the stipulated change taking place at the beginning of the year and held constant throughout the reporting period in the case of instruments that have floating rates. A 50 basis points increase or decrease is used and represents management’s assessment of the possible change in interest rates. If interest rate had been 50 (2021: 50) basis points higher or lower and all other variables were held constant, the profit before tax for the year ended December 31, 2022 of the Group would increase/decrease by RMB 12.2 million (US$ 1.8 million) (2021: increase/decrease by RMB 15.4 million). Foreign currency risk Foreign currency risk is the risk that the fair value or future cash flows of an exposure will fluctuate because of changes in foreign exchange rates. The Group’s exposure to the risk of changes in foreign exchange rates relates primarily to the Group’s sales, purchases and financial liabilities that are denominated in currencies other than the respective functional currencies of entities within the Group. The Group also holds cash and bank balances and other investments denominated in foreign currencies. The currencies giving rise to this risk are primarily the Singapore Dollar, US Dollar and Euro. Foreign currency translation exposure is managed by incurring debt in the operating currency so that where possible operating cash flows can be primarily used to repay obligations in the local currency. This also has the effect of minimizing the exchange differences recorded against income, as the exchange differences on the net investment are recorded directly against equity.

The Group is exposed to credit risk from its operating activities (primarily trade receivables) and from its financing activities, including deposits with banks and financial institutions, foreign exchange transactions and other financial instruments. Trade receivables Customer credit risk is managed by each business unit subject to the Group’s established policy, procedures and control relating to customer credit risk management. Credit limits are established for all customers based on internal rating criteria. Management has a credit policy in place and the exposure to credit risk is monitored on an ongoing basis. Credit evaluations are performed for all customers requiring credit over a certain amount. An impairment analysis is performed at each reporting date using a provision matrix. The provision rates are determined based on days past due for groupings of various customer segments with similar loss patterns (i.e. by profiles of the customers). The calculation reflects the reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions. Generally, trade receivables are written-off Set out below is the information about the credit risk exposure on the Group’s trade receivables using a provision matrix: Trade receivables Days past due As of December 31, 2021 Total Current 0 – 90 days 91-180 days 181-365 days >365 days RMB’000 RMB’000 RMB’000 RMB’000 RMB’000 RMB’000 Expected credit loss rate 9.1 % — 0.5 % 7.2 % 15.3 % 55.2 % Estimated total gross carrying amount at default 364,445 117,832 131,411 33,897 37,169 44,136 Expected credit loss 33,210 — 714 2,428 5,686 24,382 Trade receivables Days past due As of December 31, 2022 Total Current 0 – 90 days 91-180 days 181-365 days >365 days RMB’000 RMB’000 RMB’000 RMB’000 RMB’000 RMB’000 Expected credit loss rate 2.1 % — 0.2 % 0.2 % 0.6 % 63.1 % Estimated total gross carrying amount at default 1,549,462 1,138,365 216,355 80,132 63,477 51,133 Expected credit loss 33,247 — 500 124 372 32,251 At December 31, 2022, the Group had top customers (2021: top customers) that owed the Group more than RMB million (US$ Cash and fixed deposits are placed with banks and financial institutions which are regulated.

Comparative figures	36. Comparative figures The Group enters into contractual arrangements with certain customers that entitle them to sales rebates based on sales volume achieved in the financial year. Management has determined that it is more appropriate to net such sales rebates with the receivables due from these customers in the same financial year. Where receivables have been settled, such sales rebates will then be classified as refund liabilities. Accordingly, the comparative figures in the balance sheet as of December 31, 2021 for trade and other receivables and trade and other payables had been adjusted by RMB 195.4 million The changes to 2021 comparatives have no impact on the income statement, net current assets and net assets of the Group .

Basis of preparation	2.1 Basis of preparation The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The consolidated financial statements have been prepared on a historical cost basis except as disclosed in the accounting policies below. The consolidated financial statements are presented in Renminbi (“RMB”) and all values are rounded to the nearest thousand (“RMB’000”), except when otherwise indicated. Translation of amounts from Renminbi to the United States Dollar (“US Dollar”) is solely for the convenience of the reader. Translation of amounts from Renminbi to US Dollar has been made at the rate of RMB 6.9519 = US$ 1.00, the rate quoted by the People’s Bank of China at the close of business on February 28, 2023 and all values are rounded to the nearest thousand (“US$’000”), except when otherwise indicated. The consolidated financial statements provide comparative information in respect of the previous period.
Basis of consolidation	2.2 Basis of consolidation The consolidated financial statements comprise the financial statements of the Company and its subsidiaries as of December 31, 2022. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Group controls an investee if and only if the Group has: • Power over the investee (i.e. existing rights that give it the current ability to direct the relevant activities of the investee) • Exposure, or rights, to variable returns from its involvement with the investee • The ability to use its power over the investee to affect its returns Generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including: • The contractual arrangement with the other vote holders of the investee • Rights arising from other contractual arrangements • The Group’s voting rights and potential voting rights The Group re-assesses Profit or loss and each component of other comprehensive income (“OCI”) are attributed to the equity holders of the Company of the Group and to the non-controlling non-controlling A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction. If the Group loses control over a subsidiary, it derecognizes the related assets (including goodwill), liabilities, non-controlling
Business combinations and goodwill	(a) Business combinations and goodwill Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, which is measured at acquisition date fair value and the amount of any non-controlling non-controlling The Group determines that it has acquired a business when the acquired set of activities and assets include an input and a substantive process that together significantly contribute to the ability to create outputs. The acquired process is considered substantive if it is critical to the ability to continue producing outputs, and the inputs acquired include an organized workforce with the necessary skills, knowledge, or experience to perform that process or it significantly contributes to the ability to continue producing outputs and is considered unique or scarce or cannot be replaced without significant cost, effort, or delay in the ability to continue producing outputs. When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as of the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree. Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Contingent consideration classified as equity is not re-measured Financial Instruments Goodwill is initially measured at cost (being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling re-assesses After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group’s cash-generating units that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Where goodwill has been allocated to a cash-generating unit (“CGU”) and part of the operation within that unit is disposed of, the goodwill associated with the disposed operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed in these circumstances is measured based on the relative values of the disposed operation and the portion of the cash-generating unit retained. Where the Group had granted put option to third party investors (non-controlling interests) for their investments in subsidiaries, the Group recognized a financial liability based on the present value of the amount payable upon exercise of the put. A corresponding amount to equity attributable to the parent (capital reserves) will be recognized.
Investments in associates and joint ventures	(b) Investments in associates and joint ventures An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but is not control or joint control over those policies. A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control. The considerations made in determining significant influence or joint control are similar to those necessary to determine control over subsidiaries. The Group’s investments in its associates and joint ventures are accounted for using the equity method. Under the equity method, the investment in an associate or a joint venture is initially recognized at cost. The carrying amount of the investment is adjusted to recognize changes in the Group’s share of net assets of the associate or joint venture since the acquisition date. Goodwill relating to the associate or joint venture is included in the carrying amount of the investment and is not tested for impairment separately. The statement of profit or loss reflects the Group’s share of the results of operations of the associate or joint venture. Any change in OCI of those investees is presented as part of the Group’s OCI. In addition, when there has been a change recognized directly in the equity of the associate or joint venture, the Group recognizes its share of any changes, when applicable, in the statement of changes in equity. Unrealized gains and losses resulting from transactions between the Group and the associate or joint venture are eliminated to the extent of the interest in the associate or joint venture. The aggregate of the Group’s share of profit or loss of an associate and a joint venture is shown on the face of the statement of profit or loss outside operating profit and represents profit or loss after tax and non-controlling The financial statements of the associate or joint venture are prepared for the same reporting period as the Group. When necessary, adjustments are made to bring the accounting policies in line with those of the Group. After application of the equity method, the Group determines whether it is necessary to recognize an impairment loss on its investment in its associate or joint venture. At each reporting date, the Group determines whether there is objective evidence that the investment in the associate or joint venture is impaired. If there is such evidence, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate or joint venture and its carrying value, then recognizes the loss within “Share of profit/(loss) of associates and joint ventures, net of tax” in the statement of profit or loss. Upon loss of significant influence over the associate or joint control over the joint venture, the Group measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and proceeds from disposal is recognized in profit or loss.
Current versus non-current classification	(c) Current versus non-current The Group presents assets and liabilities in the statement of financial position based on current/non-current • Expected to be realized or intended to be sold or consumed in normal operating cycle; • Held primarily for the purpose of trading; • Expected to be realized within twelve months after the reporting period; or • Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period. All other assets are classified as non-current. A liability is current when: • It is expected to be settled in normal operating cycle; • It is held primarily for the purpose of trading; • It is due to be settled within twelve months after the reporting period; or • There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period. The terms of the liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification. The Group classifies all other liabilities as non-current. Deferred tax assets and liabilities are classified as non-current
Fair value measurement	(d) Fair value measurement The Group measures financial instruments, such as quoted equity securities and bills receivable and a foreign exchange forward contract, at fair value at each balance sheet date. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either: • In the principal market for the asset or liability, or • In the absence of a principal market, in the most advantageous market for the asset or liability The principal or the most advantageous market must be accessible by the Group. The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest. A fair value measurement of a non-financial The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole: • Level 1 – Quoted (unadjusted) market prices in active markets for identical assets or liabilities • Level 2 – Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable • Level 3 – Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable For assets and liabilities that are recognized in the financial statements at fair value on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above. Fair value related disclosures for financial instruments that are measured at fair value are summarized in the following notes: • Quoted equity securities Note 34 • Bills receivable Note 34 • Foreign exchange forward contract Note 34
Foreign currency translation	(e) Foreign currency translation The Company’s functional currency is US Dollar. The Group’s consolidated financial statements are presented in Renminbi, which is also the functional currency of Yuchai, the largest operating segment of the Group. Each entity in the Group determines its own functional currency, and items included in the financial statements of each entity are measured using that functional currency. Transactions and balances Transactions in foreign currencies are initially recorded by the Group’s entities at their respective functional currency spot rates at the date the transaction first qualifies for recognition. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rate of exchange at the reporting date. Differences arising on settlement or translation of monetary items are recognized in profit or loss with the exception of monetary items that are designated as part of the hedge of the Group’s net investment of a foreign operation. These are recognized in OCI until the net investment is disposed of, at which time, the cumulative amount is reclassified to profit or loss. Tax charges and credits attributable to exchange differences on those monetary items are also recorded in OCI. Non-monetary Non-monetary non-monetary In determining the spot exchange rate to use on initial recognition of the related asset, expense or income (or part of it) on the de-recognition non-monetary non-monetary non-monetary non-monetary Group companies On consolidation, the assets and liabilities of foreign operations are translated into RMB at the rate of exchange prevailing at the reporting date and their statements of profit or loss are translated at average exchange rates during the reporting period. The exchange differences arising on translation for consolidation are recognized in OCI. On disposal of a foreign operation, the component of OCI relating to that particular foreign operation is reclassified to profit or loss. Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition are treated as assets and liabilities of the foreign operation and translated at the spot rate of exchange at the reporting date.
Revenue from Contracts with Customers	(f) Revenue from Contracts with Customers Revenue from contracts with customers is recognized when control of the goods or services are transferred to the customer at an amount that reflects the consideration to which the Group expects to be entitled in exchange for those goods or services. The Group has generally concluded that it is the principal in its revenue arrangements because it typically controls the goods or services before transferring them to the customer. The disclosures of significant accounting judgements, estimates and assumptions relating to revenue from contracts with customers are provided in Note 3. Sale of engines Revenue from sale of engines is recognized at the point in time when control of the engine is transferred to the customer, generally on delivery of the engines, or, in some cases, when the engines are installed by the customers. The Group considers whether there are other promises in the contract that are separate performance obligations to which a portion of the transaction price needs to be allocated (e.g. warranties). In determining the transaction price for the sale of engines, the Group considers the effects of variable consideration and the existence of significant financing components. (i) Variable consideration If the consideration in a contract includes a variable amount, the Group estimates the amount of consideration to which it will be entitled in exchange for transferring the goods to the customer. The variable consideration is estimated at contract inception. Some contracts for the sale of engines provide customers with sales rebates based on the sales volume. The sales rebates give rise to variable consideration. Sales rebates The Group enters into contractual arrangements to provide certain customers with sales rebates when the quantity of products purchased during the period exceeds a threshold specified in the contract. Based on contractual arrangement with the customers, the sales rebates are netted against “Trade receivables”. If the receivables had been settled by the customers, amounts in excess of “Trade receivables” will be recognized as refund liabilities in “Trade and other payables”. Sales Returns The Group does not extend its sales returns policy to all customers. However the Group allows for certain returns, only on a case-by-case (ii) Significant financing component The Group receives advance payments from customers for the sale of engines. The Group applies the practical expedient for short-term advances received from customers. That is, the promised amount of consideration is not adjusted for the effects of a significant financing component if the period between the transfer of the promised good or service and the payment is one year or less. Warranty obligations The Group typically provides warranties for general repairs of defects as part of the sale of engines. These assurance-type warranties are accounted for as warranty provisions. Refer to the accounting policy on warranty provisions in Section (s) Provisions Certain contracts provide a customer with maintenance service, i.e. a distinct service to the customer in addition to the assurance that the product complies with agreed upon specification. These service-type warranties are bundled together with the sale of engines. Contracts for bundled sale of engines and a service-type warranty comprise two performance obligations because the promises to transfer the engines and to provide the service-type warranty are capable of being distinct. Using a combination of expected cost-plus margin and residual approaches, the transaction price is allocated to the service-type warranty and engines with the former performance obligation recognizing a corresponding contract liability. Revenue for service-type warranties is recognized at the point in time when the service-type warranty is provided. Sale of completed development properties Revenue is recognized when control of the property has been transferred to the customer, either over time or at a point in time, depending on the contractual terms and the practices in the legal jurisdictions. For development properties whereby the Group is restricted contractually from directing the properties for another use as they are being developed and has an enforceable right to payment for performance completed to date, revenue is recognized over time, based on the construction and other costs incurred to-date For development properties whereby the Group does not have an enforceable right to payment for performance completed to date, revenue is recognized when the customer obtains control of the asset. Rendering of services Revenue from rendering services relates to project management contracts, and hotel room and restaurant operations. Revenue is recognized over the period in which the services are rendered, by reference to completion of the specific transaction assessed on the basis of the actual service provided as a proportion of the total services to be performed. Contract balances Trade receivables A receivable is recognized if an amount of consideration that is unconditional is due from the customer (i.e. only the passage of time is required before payment of the consideration is due). Refer to accounting policies of financial assets in Section (m) Financial instruments – Initial recognition and subsequent measurement Contract liabilities A contract liability is recognized if a payment is received or a payment is due (whichever is earlier) from a customer before the Group transfers the related goods or services. Contract liabilities are recognized as revenue when the Group performs under the contract (i.e., transfers control of the related goods or services to the customer). Right of return assets A right-of-return Refund liabilities A refund liability is recognized for the obligation to refund some or all of the consideration received (or receivable) from a customer. The Group’s refund liabilities arise from customers’ right of return and sales rebates. Based on contractual arrangement with the customers, sales rebates are netted against “Trade receivables”. If the receivables had been settled by the customers, amounts in excess of “Trade receivables” will be recognized as refund liabilities. Refund liabilities arising from contractual sales returns is measured at the amount the Group ultimately expects it will have to return to the customer. The Group updates its estimates of refund liabilities arising from sales returns at the end of each reporting period. Costs to fulfil a contract Costs to fulfil a contract are capitalized if the costs relate directly to the contract, generate or enhance resources used in satisfying the contract and are expected to be recovered. Other contract costs are expensed as incurred. Capitalized contract costs are subsequently recognized in profit or loss as the Group recognizes the related revenue. An impairment loss is recognized in profit or loss to the extent that the carrying amount of the capitalized contract costs exceeds the remaining amount of consideration that the Group expects to receive in exchange for the goods or services to which the contract costs relates less the costs that relate directly to providing the goods and that have not been recognized as expenses.
Government grants	(g) Government grants Government grants are recognized where there is reasonable assurance that the grant will be received and all attached conditions will be complied with. When the grant relates to an expense item, it is recognized as income on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. When the grant relates to an asset, it is recognized as income in equal amounts over the expected useful life of the related asset.
Taxes	(h) Taxes Current income tax Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the reporting date in the countries where the Group operates and generates taxable income. Current income tax relating to items recognized directly in equity is recognized in equity and not in the statement of profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate. Deferred tax Deferred tax is provided using the liability method on temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date. Deferred tax liabilities are recognized for all taxable temporary differences, except: • When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss • In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future Deferred tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences and the carry forward of unused tax credits and unused tax losses can be utilized, except: • When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss • In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date. Deferred tax relating to items recognized outside profit or loss is recognized outside profit or loss. Deferred tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Tax benefits acquired as part of a business combination, but not satisfying the criteria for separate recognition at that date, are recognized subsequently if new information about facts and circumstances change. The adjustment is either treated as a reduction to goodwill (as long as it does not exceed goodwill) if it was incurred during the measurement period or recognized in profit or loss. The Group offsets deferred tax assets and deferred tax liabilities if and only if it has a legally enforceable right to set off current tax assets and current tax liabilities and the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered. Sales tax Expenses and assets are recognized net of the amount of sales tax, except: • When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item, as applicable • When receivables and payables are stated with the amount of sales tax included The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the statement of financial position.
Cash dividend and non-cash distribution to equity holders of the Company	(i) Cash dividend and non-cash The Company recognizes a liability to make cash or non-cash Non-cash Upon distribution of non-cash
Property, plant and equipment	(j) Property, plant and equipment Construction in progress is stated at cost, net of accumulated impairment losses, if any. Property, plant and equipment are stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. Such cost includes the cost of replacing part of the property, plant and equipment and borrowing costs for long-term construction projects if the recognition criteria are met. When significant parts of property, plant and equipment are required to be replaced at intervals, the Group depreciates them separately based on their specific useful lives. Likewise, when a major inspection is performed, its cost is recognized in the carrying amount of the plant and equipment as a replacement if the recognition criteria are satisfied. All other repair and maintenance costs are recognized in profit or loss as incurred. Freehold land has an unlimited useful life and therefore is not depreciated. Asset under construction included in property, plant and equipment are not depreciated as these assets are not yet ready for intended use. Depreciation is calculated on a straight-line basis over the estimated useful life of the assets as follows: Freehold buildings : 50 years Leasehold buildings and improvements : 50 years or period of lease, whichever is shorter Plant, machinery and equipment : 2 to 20 years Office furniture, fittings and equipment : 2 to 20 years Motor and transport vehicles : 4 to 11 years An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on de-recognition The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate. The Group capitalizes interest with respect to major assets under installation or construction based on the weighted average cost of the Group’s general borrowings and actual interest incurred for specific borrowings. Repairs and maintenance of a routine nature are expensed while those that extend the life of assets are capitalized. Construction in progress represents factories under construction and machinery and equipment pending installation. All direct costs relating to the acquisition or construction of buildings and machinery and equipment, including interest charges on borrowings, are capitalized as construction in progress.
Investment properties	(k) Investment properties Investment properties are properties owned by the Group that are held to lease to third parties and earn rentals rather than for use in the production or supply of goods or services, or for administrative purposes, or in the ordinary course of business. Investment properties comprise completed investment properties and properties that are being constructed or developed for future use as investment properties. Investment properties are initially recognized at cost, including transaction costs. Subsequent to initial recognition, investment properties are carried at cost less accumulated depreciation and impairment losses. Depreciation is recognized in profit or loss on a straight-line basis over the estimated useful lives of the investment properties. The estimated useful life is 30 years. Depreciation methods, useful lives and residual values of investment properties are reassessed at each reporting date. Investment properties are derecognized either when they have been disposed of (i.e., at the date recipient obtains control) or when they are permanently withdrawn from use and no future economic benefit is expected from its disposal. The difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period of de-recognition. de-recognition non-cash Transfers are made to (or from) investment property only when there is a change in use. Under cost model, the transfer does not change the carrying amount of the property transferred.
Intangible assets	(l) Intangible assets Intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Internally generated intangibles, excluding capitalized development costs, are not capitalized and the related expenditure is reflected in profit or loss in the period in which the expenditure is incurred. The useful lives of intangible assets are assessed as either finite or indefinite. Intangible assets with finite lives are amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statement of profit or loss in the expense category that is consistent with the function of the intangible assets. Intangible assets with indefinite useful lives are not amortized, but are tested for impairment annually, either individually or at the cash-generating unit level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be supportable. If not, the change in useful life from indefinite to finite is made on a prospective basis. An intangible asset is derecognized upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising upon de-recognition Research and development costs Research costs are expensed as incurred. Development expenditures on an individual project are recognized as an intangible asset when the Group can demonstrate: • The technical feasibility of completing the intangible asset so that the asset will be available for use or sale • Its intention to complete and its ability to use or sell the asset • How the asset will generate future economic benefits • The availability of resources to complete the asset • The ability to measure reliably the expenditure during development Following initial recognition of the development expenditure as an asset, the asset is carried at cost less any accumulated amortization and accumulated impairment losses. Amortization of the asset begins when development is complete and the asset is available for use. Development costs are amortized over the period of expected future benefit. During the period of development, the asset is tested for impairment annually. Goodwill Accounting policy for goodwill is separately discussed in Note 2.3(a). A summary of the policies applied to the Group’s intangible assets is as follows: Trademarks Technology know-how Development costs Useful lives Indefinite 8 years * Amortization method used No amortization Amortized on a straight-line basis over the period of the technology know-how * Internally generated or acquired Acquired Internally generated Internally generated * Development costs relate to on-going
Financial instruments	(m) Financial instruments – Initial recognition and subsequent measurement A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity. Financial assets Initial recognition and measurement Financial assets are classified, at initial recognition, as subsequently measured at amortized cost, fair value through other comprehensive income (“OCI”), and fair value through profit or loss. The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Group’s business model for managing them. With the exception of trade receivables that do not contain a significant financing component or which the Group has applied the practical expedient, the Group initially measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs. Trade receivables that do not contain a significant financing component or which the Group has applied the practical expedient are measured at the transaction price as disclosed in Section (f) Revenue from Contracts with Customers In order for a financial asset to be classified and measured at amortized cost or fair value through OCI, it needs to give rise to cash flows that are “solely payments of principal and interest (“SPPI”)” on the principal amount outstanding. This assessment is referred to as the SPPI test and is performed at an instrument level. Financial assets with cash flows that are not SPPI are classified and measured at fair value through profit or loss, irrespective of the business model. The Group’s business model for managing financial assets refers to how it manages its financial assets in order to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets, or both. Financial assets classified and measured at amortized cost are held within a business model with the objective to hold financial assets in order to collect contractual cash flows while financial assets classified and measured at fair value through OCI are held within a business model with the objective of both holding to collect contractual cash flows and selling. Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognized on the trade date, i.e., the date that the Group commits to purchase or sell the asset. Subsequent measurement For purposes of subsequent measurement, financial assets are classified in four categories: • Financial assets at amortized cost (debt instruments) • Financial assets at fair value through OCI with recycling of cumulative gains and losses (debt instruments) • Financial assets designated at fair value through OCI with no recycling of cumulative gains and losses upon de-recognition • Financial assets at fair value through profit or loss Financial assets at amortized cost (debt instruments) Financial assets at amortized cost are subsequently measured using the effective interest (“EIR”) method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired. The Group’s financial assets at amortized cost includes trade and other receivables, and certain bills receivables that are held to maturity. Financial assets at fair value through OCI (debt instruments) For debt instruments at fair value through OCI, interest income, foreign exchange revaluation and impairment losses or reversals are recognized in the statement of profit or loss and computed in the same manner as for financial assets measured at amortized cost. The remaining fair value changes are recognized in OCI. Upon de-recognition, The Group’s debt instruments at fair value through OCI includes certain bills receivable that are not held to maturity. Financial assets designated at fair value through OCI (equity instruments) Upon initial recognition, the Group can elect to classify irrevocably its equity investments as equity instruments designated at fair value through OCI when they meet the definition of equity under IAS 32 Financial Instruments: Presentation instrument-by-instrument Gains and losses on these financial assets are never recycled to profit or loss. Dividends are recognized as other income in the statement of profit or loss when the right of payment has been established, except when the Group benefits from such proceeds as a recovery of part of the cost of the financial asset, in which case, such gains are recorded in OCI. Equity instruments designated at fair value through OCI are not subject to impairment assessment. The Group does not have equity instruments measured under this category. Financial assets at fair value through profit or loss Financial assets at fair value through profit or loss are carried in the statement of financial position at fair value with net changes in fair value recognized in statement of profit or loss. This category includes derivative instruments and listed equity investments which the Group had not irrevocably elected to classify at fair value through OCI. Dividends on listed equity investments are also recognized as other income in the statement of profit or loss when the right of payment has been established. A derivative embedded in a hybrid contract, with a financial liability or non-financial Derecognition A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e., removed from the Group’s consolidated statement of financial position) when: • The rights to receive cash flows from the asset has expired; or • The Group has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a “pass-through” arrangement; and either (a) the Group has transferred substantially all the risks and rewards of the asset, or (b) the Group has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset When the Group has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if, and to what extent, it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Group continues to recognize the transferred asset to the extent of its continuing involvement. In that case, the Group also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained. Continuing involvement that takes the form a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Group could be required to repay. Impairment Further disclosures relating to impairment of financial assets are also provided in the following notes: • Debt instruments at fair value through OCI represented by bills receivable (Note 15) • Trade receivables (Note 15) The Group recognizes an allowance for expected credit losses (“ECLs”) for all debt instruments not held at fair value through profit or loss and financial guarantee contracts. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and the cash flows that the Group expects to receive, discounted at an approximation of the original effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms. ECLs are recognized in two stages. For credit exposure for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses that result from default events that are possible within the next 12 months (a “12-month For trade receivable, the Group applies a simplified approach in calculating ECLs. Therefore, the Group does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime ECLs at each reporting date. The Group has established a provision matrix that is based on its historical credit loss experience adjusted for forward-looking factors specific to the debtors and the economic environment. For debt instruments at fair value through OCI, the Group applies the low credit risk simplifications. At every reporting date, the Group evaluate whether the debt instrument is considered to have low credit risk using all reasonable and supportable information that is available without undue cost or effort. In making the evaluation, the Group reassesses the external credit rating of the debt instrument. In addition, the Group considers that there has been a significant increase in credit risk when contractual payments are more than 30 days past due. The Group’s debt instruments at fair value through OCI comprise solely of bills receivable. It is the Group’s policy to measure ECLs on such instruments on a 12-month The Group considers a financial asset in default when contractual payments are more than 360 days from the invoice date. However, in certain cases the Group may also consider a financial asset to be in default when internal or external information indicates that the Group is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Group. A financial asset is written off when there is no reasonable expectation of recovering contractual cash flow. Financial liabilities Initial recognition and measurement Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate. All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs. The Group’s financial liabilities include trade and other payables, loans and borrowings, lease liabilities, other liabilities and derivative financial instruments. Subsequent measurement For purposes of subsequent measurement, financial liabilities are classified in two categories: • Financial liabilities at fair value through profit or loss • Financial liabilities at amortized cost Financial liabilities at fair value through profit or loss Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Group that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments. Gains or losses on liabilities held for trading are recognized in the statement of profit or loss. Financial liabilities designated upon initial recognition at fair value through profit or loss are designated at the initial date of recognition, and only if the criteria in IFRS 9 are satisfied. The Group has not designated any financial liability as at fair value through profit or loss. Financial liabilities at amortized cost This is the category most relevant to the Group. After initial recognition, financial liabilities that are not carried at fair value through profit or loss are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the statement of profit or loss. This category generally applies to loans and borrowings, lease liabilities, other liabilities and payables. For more information, refer to Note 22, 25, 26 and 28. De-recognition A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the de-recognition Offsetting of financial instruments Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statement of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.
Inventories	(n) Inventories Inventories are valued at the lower of cost and net realizable value. Costs incurred in bringing each product to its present location and condition are accounted for as follows: • Raw materials: purchase cost on a weighted average basis • Finished goods and work in progress: cost of direct materials and labor and a proportion of manufacturing overheads based on the normal operating capacity, but excluding borrowing costs Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs necessary to make the sale.
Impairment of non-financial assets	(o) Impairment of non-financial Further disclosures relating to impairment of non-financial • Disclosures for significant assumptions (Note 3) • Investment in joint ventures (Note 5) • Property, plant and equipment (Note 10) • Investment property (Note 11) • Intangible assets (Note 12) • Right-of-use The Group assesses, at each reporting date, whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing for an asset is required, the Group estimates the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s or CGU’s fair value less costs of disposal and its value in use. The recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax The Group bases its impairment calculation on detailed budgets and forecast calculations, which are prepared separately for each of the Group’s CGUs to which the individual assets are allocated. These budgets and forecast calculations generally cover a period of seven to ten years. A long-term growth rate is calculated and applied to project future cash flows after the tenth year where appropriate. Impairment losses are recognized in the statement of profit or loss in expense categories consistent with the function of the impaired asset. For assets excluding goodwill, an assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses no longer exist or have decreased. If such indication exists, the Group estimates the asset’s or CGU’s recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset’s recoverable amount since the last impairment loss was recognized. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the statement of profit or loss. Goodwill is tested for impairment annually and when circumstances indicate that the carrying value may be impaired. Impairment is determined for goodwill by assessing the recoverable amount of each CGU (or group of CGUs) to which the goodwill relates. When the recoverable amount of the CGU is less than its carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods. Intangible assets with indefinite useful lives are tested for impairment annually at the CGU level, as appropriate, and when circumstances indicate that the carrying value may be impaired.
Cash and cash equivalents	(p) Cash and cash equivalents For the purpose of the consolidated statement of cash flows, cash and cash equivalents in the statement of financial position comprise cash at banks and on hand, short-term highly liquid deposits with a maturity of three months or less, that are readily convertible to a known amount of cash and subject to an insignificant risk of changes in value.
Leases	(q) Leases The Group assess at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Group as a lessee The Group applies a single recognition and measurement approach for all leases, expect for short-term leases and leases of low-value right-of-use (i) Right-of-use The Group recognizes right-of-use Right-of-use re-measurement right-of-use Right-of-use • Leasehold land 3 to 50 years • Building and office space 1 to 6 years • Office furniture, fittings and equipment 5 years • Motor vehicles 12 years If ownership of the leased asset transfers to the Group at the end of the lease term or the cost reflects the exercise of a purchase option, depreciation is calculated using the estimated useful life of the asset. The right-of-use Impairment of non-financial (ii) Lease liabilities At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in-substances In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is re-measured (iii) Short-term leases The Group applies the short-term lease recognition exemption to its short-term leases of land and building (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). Lease payments on short-term leases are recognized as expense on a straight-line basis over the lease term. Group as a lessor Leases in which the Group does not transfer substantially all the risks and rewards of ownership of an asset are classified as operating leases. Rental income arising is accounted for on straight-line basis over the lease terms and is included in revenue in the statement of profit or loss due to its operating nature. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized over the lease term on the same basis as rental income.
Borrowing costs	(r) Borrowing costs Borrowing costs directly attributable to the acquisition, construction or production of an asset that necessarily takes a substantial period of time to get ready for its intended use or sale are capitalized as part of the cost of the asset. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consist of interest and other costs that an entity incurs in connection with the borrowing of funds.
Provisions	(s) Provisions General Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. When the Group expects some or all of a provision to be reimbursed, the reimbursement is recognized as a separate asset, but only when the reimbursement is virtually certain. The expense relating to a provision is presented in the statement of profit or loss net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a current pre-tax Product warranty The Group recognizes a liability at the time the product is sold, for the estimated future costs relating to the assurance-type warranties, to be incurred under the lower of a warranty period or warranty mileage on various engine models, on which the Group provides free repair and replacement. For on-road Onerous contract If the Group has a contract that is onerous, the present obligation under the contract is recognized and measured as a provision. However, before a separate provision for an onerous contract is established, the Group recognizes any impairment loss that has occurred on assets dedicated to that contract. An onerous contract is a contract under which the unavoidable costs (i.e., the costs that the Group cannot avoid because it has the contract) of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The unavoidable costs under a contract reflect the least net cost of exiting from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfil it. The cost of fulfilling a contract comprises the costs that relate directly to the contract (i.e., both incremental costs and an allocation of costs directly related to contract activities).
Pensions and other post-employment benefits	(t) Pensions and other post-employment benefits Defined contribution plans The Group participates in and makes contributions to the national pension schemes as defined by the laws of the countries in which it has operations. The contributions are at a fixed proportion of the basic salary of the staff. Contributions to defined contribution pension schemes are recognized as an expense in the period in which the related services are performed. Employee leave entitlement Employee entitlements to annual leave are recognized as a liability when they are accrued to the employees. The undiscounted liability for leave expected to be settled wholly before twelve months after the end of the reporting period is recognized for services rendered by employees up to the end of the reporting period.
Share-based payments	(u) Share-based payments Employees (including senior executives) of the Group receive remuneration in the form of share-based payments, whereby employees render services as consideration for equity instruments (“equity-settled transactions”). Equity-settled transactions The cost of equity-settled transactions is determined by the fair value at the date when the grant is made using an appropriate valuation model, further details of which are given in Note 21. That cost is recognized in “Staff costs”, together with a corresponding increase in performance share reserve in equity, over the period in which the performance and/or service conditions are fulfilled (the vesting period). The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Group’s best estimate of the number of equity instruments that will ultimately vest. The expense or credit in the statement of profit or loss for a period represents the movement in cumulative expense recognized as of the beginning and end of that period. No expense is recognized for awards that do not ultimately vest, except for equity-settled transactions for which vesting is conditional upon a market or non-vesting non-vesting When the terms of an equity-settled award are modified, the minimum expense recognized is the expense had the terms not been modified, provided the original terms of the award are met. An additional expense, measured as of the date of modification, is recognized for any modification that increases the total fair value of the share-based payment transaction, or is otherwise beneficial to the employee. Where an award is cancelled by the entity or by the counterparty, any remaining element of the fair value of the award is expensed immediately through profit or loss. The dilutive effect of outstanding options is reflected as additional share dilution in the computation of diluted earnings per share (further details are given in Note 9).
Development properties	(v) Development properties Development properties are properties acquired or being constructed for sale in the ordinary course of business, rather than to be held for the Group’s own use, rental or capital appreciation. Development properties are held as other asset and are measured at the lower of cost and net realizable value. Costs to complete development include cost of land and other direct and related development expenditure, including borrowing costs incurred in developing the properties. Net realizable value of development properties is the estimated selling price in the ordinary course of business, based on market prices at the reporting date and discounted for the time value of money if material, less the estimated costs of completion and the estimated costs necessary to make the sale. The costs of development properties recognized in profit or loss on disposal are determined with reference to the specific costs incurred on the property sold and an allocation of any non-specific
Derivative financial instruments	(w) Derivative financial instruments Initial recognition and subsequent measurement The Group uses derivative financial instruments, such as forward currency contracts, to hedge its foreign currency risks. Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured
Changes in accounting policies and disclosures	2.4 Changes in accounting policies and disclosures New and amended standards and interpretations The Group applied for the first-time certain standards and amendments, which are effective for annual periods beginning on or after January 1, 2022. The Group has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective. Onerous Contracts – Costs of Fulfilling a Contract – Amendments to IAS 37 An onerous contract is a contract under which the unavoidable of meeting the obligations under the contract costs (i.e., the costs that the Group cannot avoid because it has the contract) exceed the economic benefits expected to be received under it. The amendments specify that when assessing whether a contract is onerous or loss-making, an entity needs to include costs that relate directly to a contract to provide goods or services including both incremental costs (e.g., the costs of direct labour and materials) and an allocation of costs directly related to contract activities (e.g., depreciation of equipment used to fulfil the contract and costs of contract management and supervision). General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract. These amendments had no impact on the consolidated financial statements of the Group as the Group didn’t not include the general and administrative costs that do not relate to the contract. Reference to the Conceptual Framework – Amendments to IFRS 3 The amendments replace a reference to a previous version of the IASB’s Conceptual Framework with a reference to the current version issued in March 2018 without significantly changing its requirements. The amendments add an exception to the recognition principle of IFRS 3 Business Combinations to avoid the issue of potential “day 2” gains or losses arising for liabilities and contingent liabilities that would be within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets Levies The amendments also add a new paragraph to IFRS 3 to clarify that contingent assets do not qualify for recognition at the acquisition date. These amendments had no impact on the consolidated financial statements of the Group as there were no contingent assets, liabilities or contingent liabilities within the scope of these amendments that arose during the period. Property, Plant and Equipment: Proceeds before Intended Use – Amendments to IAS 16 The amendment prohibits entities from deducting from the cost of an item of property, plant and equipment, any proceeds of the sale of items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the costs of producing those items, in profit or loss. These amendments had no impact on the consolidated financial statements of the Group as there were no sales of such items produced by property, plant and equipment made available for use on or after the beginning of the earliest period presented. IFRS 1 First-time Adoption of International Financial Reporting Standards – Subsidiary as a first-time adopter The amendment permits a subsidiary that elects to apply paragraph D16(a) of IFRS 1 to measure cumulative translation differences using the amounts reported in the parent’s consolidated financial statements, based on the parent’s date of transition to IFRS, if no adjustments were made for consolidation procedures and for the effects of the business combination in which the parent acquired the subsidiary. This amendment is also applied to an associate or joint venture that elects to apply paragraph D16(a) of IFRS 1. These amendments had no impact on the consolidated financial statements of the Group as it is not a first time adopter. IFRS 9 Financial Instruments de-recognition The amendment clarifies the fees that an entity includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. These fees include only those paid or received between the borrower and the lender, including fees paid or received by either the borrower or lender on the other’s behalf. There is no similar amendment proposed for IAS 39 Financial Instruments: Recognition and Measurement These amendments had no impact on the consolidated financial statements of the Group as there were no modifications of the Group’s financial instruments during the period.
Standards issued but not yet effective	2.5 Standards issued but not yet effective The new and amended standards and interpretations that are issued, but not yet effective are disclosed below. The Group intends to adopt these new and amended standards and interpretations, if applicable, when they become effective. Amendments to IAS 1: Classification of Liabilities as Current or Non-current In January 2020, the IASB issued amendments to paragraphs 69 to 76 of IAS 1 to specify the requirements for classifying liabilities as current or non-current. • What is meant by a right to defer settlement • That a right to defer must exist at the end of the reporting period • That classification is unaffected by the likelihood that an entity will exercise its deferral right • That only if an embedded derivative in a convertible liability is itself an equity instrument would the terms of a liability not impact its classification The amendments are effective for annual reporting periods beginning on or after January 1, 2023 and must be applied retrospectively. The Group is currently assessing the impact. Definition of Accounting Estimates Amendments to IAS 8 In February 2021, the IASB issued amendments to IAS 8, in which it introduces a definition of “accounting estimates”. The amendments clarify the distinction between changes in accounting estimates and changes in accounting policies and the correction of errors. Also, they clarify how entities use measurement techniques and inputs to develop accounting estimates. The amendments are effective for annual reporting periods beginning on or after January 1, 2023 and apply to changes in accounting policies and changes in accounting estimates that occur on or after the start of that period. Earlier application is permitted as long as this fact is disclosed. The amendments are not expected to have a material impact on the Group. Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2 In February 2021, the IASB issued amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgements The amendments to IAS 1 are applicable for annual periods beginning on or after January 1, 2023 with earlier application permitted. Since the amendments to the Practice Statement 2 provide non-mandatory The Group is currently assessing the impact of the amendments to determine the impact that will have on the Group’s accounting policy disclosures. Deferred Tax related to Assets and Liabilities arising from a Single Transaction - Amendments to IAS 12 In May 2021, the IASB issued amendments to IAS 12 The amendments clarify that where payments that settle a liability are deductible for tax purposes, it is a matter of judgement (having considered the applicable tax law) whether such deductions are attributable for tax purposes to the liability recognized in the financial statements (and interest expense) or to the related asset component (and interest expense). This judgement is important in determining whether any temporary differences exist on initial recognition of the asset and liability. Under the amendments, the initial recognition exception does not apply to transactions that, on initial recognition, give rise to equal taxable and deductible temporary differences. It only applies if the recognition of a lease asset and lease liability (or decommissioning liability and decommissioning asset component) give rise to taxable and deductible temporary differences that are not equal. Nevertheless, it is possible that the resulting deferred tax assets and liabilities are not equal (e.g., if the entity is unable to benefit from the tax deductions or if different tax rates apply to the taxable and deductible temporary differences). In such cases, which the IASB expects to occur infrequently, an entity would need to account for the difference between the deferred tax asset and liability in profit or loss. The amendment is effective for annual reporting periods beginning on or after January 1, 2023. The amendments are not expected to have a material impact on the Group. Lease Liability in a Sale and Leaseback - Amendments to IFRS 16 In September 2022, the IASB issued Lease Liability in a Sale and Leaseback ( Amendments to IFRS 16 amendment to IFRS 16 Leases The amendment is intended to improve the requirements for sale and leaseback transactions in IFRS 16. It does not change the accounting for leases unrelated to sale and leaseback transactions. The amendment applies retrospectively to annual reporting periods beginning on or after January 1, 2024. Earlier application is permitted. The amendments are not expected to have a material impact on the Group. Amendments to IFRS 17 Insurance Contracts In May 2017, the IASB issued IFRS 17 Insurance Contracts Insurance Contracts • A specific adaptation for contracts with direct participation features (the variable fee approach) • A simplified approach (the premium allocation approach) mainly for short-duration contracts IFRS 17 is effective for reporting periods beginning on or after January 1, 2023, with comparative figures required. Early application is permitted, provided the entity also applies IFRS 9 and IFRS 15 on or before the date it first applies IFRS 17. The amendments are not expected to have a material impact on the Group.
