At the same time, the risks resulting from the rapid changes in domestic and overseas macro economic environment, the emergence of new industry competitive dynamic and the transformation of new and old growth drivers will bring new challenges to the corporate development in the future. In 2021, facing the complicated changes in the internal and external environment, the Company will firmly grasp the key opportunities for the scale development of 5G, continue to deeply implement the strategy of focus, innovation and cooperation, accelerate the comprehensive digital transformation and focus on shaping the 'Five-high' new development edges with high-quality service, high-quality development, highly effective governance, high-tech engine and high-vitality operation.

Lastly, on behalf of the Board of Directors, I would like to express our sincere gratitude to all shareholders, customers and fellows across society for their support and to all employees for their continuous dedication and contribution along the way! Wang Xiaochu Chairman and Chief Executive Officer Hong Kong, 11 March 2021 Note 1: EBITDA represents profit for the year before finance costs, interest income, share of net profit of associates, share of net profit of joint ventures, other income-net, income tax expenses, depreciation and amortisation. As the telecommunications business is a capital intensive industry, capital expenditure and finance costs may have a significant impact on the net profit of the companies with similar operating results. Therefore, the Company believes that EBITDA may be helpful in analysing the operating results of a telecommunications service operator like the Company. However, it is a non-GAAP financial measure which does not have a standardised meaning and therefore may not be comparable to similar measures presented by other companies. Note 2: Free cash flow represents operating cash flow less capital expenditure. However, it is a non-GAAP financial measure which does not have a standardised meaning and therefore may not be comparable to similar measures presented by other companies. ANNUAL REPORT 2020 13

NYSE COMMENCED PROCEEDINGS TO DELIST THE ADSs

The former US President issued an executive order 13959 (the 'Executive Order') on 12 November 2020, and subsequently the US Department of Treasury's Office of Foreign Assets Control issued the guidance. The Executive Order and the guidance prohibit any transaction by any US person in publicly traded securities (including, among others, derivatives thereof) of certain Chinese companies, including the Company.

The New York Stock Exchange ('NYSE') staff determined that, based on the Executive Order and the guidance, it commenced the process to delist the Company's American Depositary Shares (the 'ADSs') and suspended trading in the Company's ADSs from 11 January 2021. Since its listing on The Stock Exchange of Hong Kong Limited and the NYSE in 2000, the Company has complied strictly with the laws and regulations, market rules as well as regulatory requirements of its listing venues, and has been operating in accordance with laws and regulations. The Company was disappointed by the Executive Order and NYSE decisions, which led to a negative impact on the trading prices of its ordinary shares and ADSs and harmed the interests of the Company and its shareholders. In order to protect the interests of the Company and its shareholders, on 20 January 2021, the Company filed with the NYSE a written request for a review of the determination by a Committee of the Board of Directors of the NYSE. Please refer to the Company's announcement dated 21 January 2021 for details. The Company will continue to pay close attention to the development of related matters and also seek professional advice and reserve all rights to protect lawful rights of the Company.

INDEPENDENT AUDITOR'S REPORT

TO THE MEMBERS OF CHINA UNICOM (HONG KONG) LIMITED

(incorporated in Hong Kong with limited liability)

Opinion

We have audited the consolidated financial statements of China Unicom (Hong Kong) Limited ('the Company') and its subsidiaries ('the Group') set out on pages 93 to 185, which comprise the consolidated statement of financial position as at 31 December 2020, the consolidated statement of income, the consolidated statement of comprehensive income, the consolidated statement of changes in equity and the consolidated statement of cash flows for the year then ended and notes to the consolidated financial statements, including a summary of significant accounting policies.

In our opinion, the consolidated financial statements give a true and fair view of the consolidated financial position of the Group as at 31 December 2020 and of its consolidated financial performance and its consolidated cash flows for the year then ended in accordance with International Financial Reporting Standards ('IFRSs') issued by the International Accounting Standards Board ('IASB') and Hong Kong Financial Reporting Standards ('HKFRSs') issued by the Hong Kong Institute of Certified Public Accountants ('HKICPA') and have been properly prepared in compliance with the Hong Kong Companies Ordinance.

Basis for opinion

We conducted our audit in accordance with Hong Kong Standards on Auditing ('HKSAs') issued by the HKICPA. Our responsibilities under those standards are further described in the Auditor's responsibilities for the audit of the consolidated financial statements section of our report. We are independent of the Group in accordance with the HKICPA's Code of Ethics for Professional Accountants ('the Code') and we have fulfilled our other ethical responsibilities in accordance with the Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the consolidated financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

88 CHINA UNICOM (HONG KONG) LIMITED

Revenue recognition

Refer to note 6 to the consolidated financial statements on page 133 and the accounting policies on page 118 to 119.

The Key Audit Matter How the matter was addressed in our audit

The Group's revenue is primarily generated from the provision of voice usage, broadband and mobile data services, data and internet application services, other value-added services, transmission lines usage and associated services and sales of telecommunications products.

The accuracy of revenue recorded in the consolidated financial statements is an inherent industry risk because the billing systems of telecommunications companies are complex and process large volumes of data with a combination of different products sold during the year, through a number of different systems.

Significant management judgement can be required in determining the appropriate measurement and timing of recognition of different performance obligations within contracts containing bundled sales packages, which may include services and telecommunication products such as handsets, and complex settings are required in the Group's information technology ('IT') systems to achieve the appropriate allocation of transaction prices.

We identified revenue recognition as a key audit matter because revenue is one of the key performance indicators of the Group and because it involves complex IT systems and management judgement both of which give rise to an inherent risk that revenue could be recorded in the incorrect period or could be subject to manipulation to meet targets or expectations.

Our audit procedures to assess the recognition of revenue included the following:

assessing, with the assistance of our internal IT specialists, the design, implementation and operating effectiveness of management's key internal controls over the general IT environment in which the business systems operate, including access to program controls, program change controls, program development controls and computer operation controls;

assessing, with the assistance of our internal IT specialists, the design, implementation and operating effectiveness of management's key internal IT controls over the completeness and accuracy of rating and bill generation and the end-to-end reconciliation controls from the rating and billing systems to the accounting system;

selecting bills issued to customers, on a sample basis, and comparing the details with the corresponding accounts receivable details and cash receipts;

reconciling the Group's revenue to the cash collection records on a sample basis;

recalculating the balances of accounts receivable and advances from customers with the use of electronic audit tools using data extracted from the business support systems and reconciling the results to the Group's financial records;

assessing, on a sample basis, the standalone selling prices determined by the Group for services and handsets offered in mobile handset bundled sales packages, by comparison with the observable prices of the service or handset when the Group sells that service or handset separately in similar circumstances and to similar customers;

assessing, on a sample basis, the settings in the IT system for revenue allocation between the services and handsets offered in mobile handset bundled sales packages by comparing the settings with the Group's allocation basis and recalculating and comparing the allocation results with the system generated results;

evaluating journals entries posted to revenue accounts, on a specific risk-based sample basis, and comparing details of these journals entries with relevant underlying documentation, which included service contracts and progress reports.

ANNUAL REPORT 2020 89

INDEPENDENT AUDITOR'S REPORT

Carrying value of property, plant and equipment ('PP&E')

Refer to note 15 to the consolidated financial statements on pages 144 to 145 and the accounting policies on pages 109 to 110.

The Key Audit Matter How the matter was addressed in our audit

The Group continues to incur a significant level of capital expenditure in connection with the expansion of its network coverage and improvements to network quality. The carrying value of PP&E as at 31 December 2020 was approximately RMB364,187 million.

There are a number of areas where management judgement impacts the carrying value of PP&E, and the related depreciation profiles. These include:

determining which costs meet the criteria for capitalisation;

determining the date on which construction-in-progress is transferred to property, plant and equipment and depreciation commences;

the estimation of economic useful lives and residual values assigned to property, plant and equipment.

We identified the carrying value of property, plant and equipment as a key audit matter because of the high level of management judgement involved and because of its significance to the consolidated financial statements.

Our audit procedures to assess the carrying value of PP&E included the following:

assessing the design, implementation and operating effectiveness of key internal controls over the completeness, existence and accuracy of property, plant and equipment, including the key internal controls over the estimation of useful economic lives and residual values;

assessing, on a sample basis, costs capitalised during the year by comparing the costs capitalised with the relevant underlying documentation, which included

purchase agreements and invoices, and assessing whether the costs capitalised met the relevant criteria for capitalisation; which included comparing interest rates to loan agreements, recalculating the interest capitalisation rate and assessing, on a sample basis, the calculation of interest capitalised in construction-in-progress;

challenging the date of transferring construction-in-progress to PP&E by examining the inspection reports and/or project progress reports, on a sample basis;

evaluating management's estimation of useful economic lives and residual values by considering our knowledge of the business and practices adopted in the wider telecommunications industry.

Information other than the consolidated financial statements and auditor's report thereon

The directors are responsible for the other information. The other information comprises all the information included in the annual report, other than the consolidated financial statements and our auditor's report thereon.

Our opinion on the consolidated financial statements does not cover the other information and we do not express any form of assurance conclusion thereon.

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the consolidated financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated.

If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

90 CHINA UNICOM (HONG KONG) LIMITED

Responsibilities of the directors for the consolidated financial statements

The directors are responsible for the preparation of the consolidated financial statements that give a true and fair view in accordance with IFRSs issued by the IASB and HKFRSs issued by the HKICPA and the Hong Kong Companies Ordinance and for such internal control as the directors determine is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

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

The directors are assisted by the Audit Committee in discharging their responsibilities for overseeing the Group's financial reporting process.

Auditor's responsibilities for the audit of the consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. This report is made solely to you, as a body, in accordance with section 405 of the Hong Kong Companies Ordinance, and for no other purpose. We do not assume responsibility towards or accept liability to any other person for the contents of this report.

Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with HKSAs will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with HKSAs, we exercise professional judgement and maintain professional scepticism throughout the audit. We also:

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

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

Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors.

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

ANNUAL REPORT 2020 91

INDEPENDENT AUDITOR'S REPORT

Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

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

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

We also provide the Audit Committee with a statement that we have complied with relevant ethical requirements regarding independence and communicate with them all relationships and other matters that may reasonably be thought to bear on our independence and, where applicable, actions taken to eliminate threats or safeguards applied.

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

The engagement partner on the audit resulting in this independent auditor's report is Chan Kim Tak.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.2 Basis of preparation

The consolidated financial statements have been prepared under the historical cost convention, except that the following assets are stated at their fair value set out below:

• Financial assets measured at fair value

The consolidated financial statements prepared by the PRC subsidiaries for PRC statutory reporting purposes are based on the Chinese Accounting Standards for Business Enterprises ('CAS') issued by the Ministry of Finance ('MOF') of the PRC, which became effective from 1 January 2007 with certain transitional provisions. There are certain differences between the Group's IFRS/HKFRS financial statements and PRC financial statements. The principal adjustments made to the PRC financial statements to conform to IFRSs/HKFRSs include the following:

• reversal of the revaluation surplus or deficit and related amortisation charges arising from the revaluation of prepayments for the leasehold land performed by independent valuers for the purpose of reporting to relevant PRC government authorities, and adjustment for corresponding deferred taxation;

• recognition of goodwill associated with the acquisition of certain subsidiaries prior to 2005; and

• recognition of the dilution gain or loss of interest in equity-accounted investee.

(a) Going Concern Assumption

As at 31 December 2020, current liabilities of the Group exceeded current assets by approximately RMB113.4 billion (2019: approximately RMB121.6 billion). Considering the current economic conditions and taking into account of the Group's expected capital expenditure in the foreseeable future, management has comprehensively considered the Group's available sources of funds as follows:

• The Group's continuous net cash inflows from operating activities;

• Approximately RMB352.4 billion of revolving banking facilities and registered quota of corporate bonds, of which approximately RMB348.4 billion was unutilised as at 31 December 2020; and

• Other available sources of financing from domestic banks and other financial institutions in view of the Group's good credit history.

In addition, the Group believes it has the ability to raise funds from short, medium and long-term perspectives and maintain reasonable financing costs through appropriate financing portfolio.

Based on the above considerations, the Board of Directors is of the opinion that the Group has sufficient funds to meet its working capital commitments, expected capital expenditure and debt obligations. As a result, the consolidated financial statements of the Group for the year ended 31 December 2020 have been prepared on a going concern basis.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.2 Basis of preparation (Continued)

(b) Critical Accounting Estimates and Judgment

The preparation of the consolidated financial statements in conformity with IFRSs/HKFRSs requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets, liabilities, income and expenses. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making the judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

Judgments made by management in the application of IFRSs/HKFRSs that have significant effect on the financial statements and major sources of estimation uncertainty are discussed in Note 4.

(c) New Accounting Standards and Amendments

The IASB and HKICPA have issued a number of amendments to IFRSs/HKFRSs and IASs/HKASs that are first effective for the current accounting period of the Group. Of these, the following amendments are relevant to the Group's consolidated

financial statements:

Amendments to IFRS/HKFRS 3, 'Definition of a business'

Amendments to IFRS/HKFRS 9, IAS/HKAS 39 and IFRS/HKFRS 7, 'Interest Rate Benchmark Reform'

Amendments to IAS/HKAS 1 and IAS/HKAS 8, 'Definition of Material'

Amendments to IFRS/HKFRS 16, 'Covid-19-Related Rent Concessions'

None of the amendments have had a material effect on how the Group's results and financial position for the current or prior periods have been prepared or presented in this consolidated financial statements. The Group has not applied any new standard or interpretation that is not yet effective for the current accounting period. In particular, the Group does not take advantage of the practice expedient available under the amendments to IFRS/HKFRS 16, 'Covid-19-related Rent Concessions' on lease modifications.

(d) Possible impact of amendments, new standards and interpretations issued but not yet effective for the year ended 31 December 2020.

The IASB and HKICPA has issued a number of amendments to IFRSs/HKFRSs and IASs/HKASs which are not yet effective for the year ended 31 December 2020 and which have not been adopted in these consolidated financial statements. Of these, the following developments are relevant to the Group's consolidated financial statements:

Effective for accounting periods beginning on or after

Amendments to IFRS/HKFRS 9, IAS/HKAS 39, IFRS/HKFRS 7, IFRS/HKFRS 4 and IFRS/

HKFRS 16, 'Interest Rate Benchmark Reform - Phase 2' 1 January, 2021 Amendments to IFRS/HKFRS 3, 'Reference to the Conceptual Framework' 1 January, 2022 Amendments to IAS/HKAS 16, 'Property, Plant and Equipment: Proceeds before Intended Use' 1 January, 2022 Amendments to IAS/HKAS 37, 'Onerous Contracts-Cost of Fulfilling a Contract' 1 January, 2022 Annual Improvements to IFRS/HKFRS Standards 2018-2020 1 January, 2022 Amendments to IAS/HKAS 1, 'Classification of Liabilities as Current or Non-current' 1 January, 2023

The Group is assessing the impact of such amendments to standards and interpretations, and will adopt the relevant amendments to standards and interpretations in the subsequent period as required. So far it has concluded that the adoption of them is unlikely to have a significant impact on the consolidated financial statements.

2.3 Subsidiaries and non-controlling interests

Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed, or has rights to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. When assessing whether the Group has power, only substantive rights (held by the Group and other parties) are considered.

An investment in a subsidiary is consolidated into the consolidated financial statements from the date that control commences until the date that control ceases. Intra-group balances, transactions and cash flows and any unrealised profits arising from intragroup transactions are eliminated in full in preparing the consolidated financial statements. Unrealised losses resulting from intra-group transactions are eliminated in the same way as unrealised gains but only to the extent that there is no evidence of impairment.

The Group adopted the purchase method of accounting to account for business combination of entities and businesses under common control before 2005. Under the purchase method of accounting in force at the date of the acquisition, the cost of an acquisition was measured at the fair value of the assets given, equity instruments issued and liabilities incurred or assumed at the date of exchange, plus costs directly attributable to the acquisition. Identifiable assets acquired and liabilities and contingent liabilities assumed were measured initially at their fair values at the acquisition date, irrespective of the extent of any non-controlling interest. The excess of the cost of acquisition over the fair value of the Group's share of the identifiable net assets acquired was recorded as goodwill. If the cost of acquisition was less than the fair value of the Group's share of the identifiable net assets of the subsidiary acquired, the difference was recognised directly in the statement of income.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.3 Subsidiaries and non-controlling interests (Continued)

Under HKFRSs, business combination of entity and business under common control of the Group after 2005 was accounted for using merger accounting in accordance with the Accounting Guideline 5 'Merger accounting for common control combinations' ('AG 5') issued by the HKICPA in 2005. Upon the adoption of IFRSs by the Group in 2008, the Group adopted the accounting policy to account for business combinations of entities and businesses under common control using the predecessor values method, which is consistent with HKFRSs.

Non-controlling interests represent the equity in a subsidiary not attributable directly or indirectly to the Company, and in respect of which the Group has not agreed any additional terms with the holders of those interests which would result in the Group as a whole having a contractual obligation in respect of those interests that meets the definition of a financial liability. For each business combination, the Group can elect to measure any non-controlling interests either at fair value or at the non-controlling interests' proportionate share of the subsidiary's net identifiable assets.

Non-controlling interests are presented in the consolidated statement of financial position within equity, separately from equity attributable to the equity shareholders of the Company. Non-controlling interests in the results of the Group are presented on the face of the consolidated statement of income and the consolidated statement of comprehensive income as an allocation of the total profit or loss and total comprehensive income for the year between non-controlling interests and the equity shareholders of the Company. Loans from holders of non-controlling interests and other contractual obligations towards these holders are presented as financial liabilities in the consolidated statement of financial position in accordance with Note 2.20 depending on the nature of the liability.

Changes in the Group's interests in a subsidiary that do not result in a loss of control are accounted for as equity transactions, whereby adjustments are made to the amounts of controlling and non-controlling interests within consolidated equity to reflect the change in relative interests, but no adjustments are made to goodwill and no gain or loss is recognised.

When the Group loses control of a subsidiary, it is accounted for as a disposal of the entire interest in that subsidiary, with a resulting gain or loss being recognised in profit or loss. Any interest retained in that former subsidiary at the date when control is lost is recognised at fair value and this amount is regarded as the fair value on initial recognition of a financial asset (see Note

2.12) or, when appropriate, the cost on initial recognition of an investment in an associate or joint venture (see Note 2.4).

In the Company's statement of financial position, an investment in a subsidiary is stated at cost less impairment losses (see Note

2.13), unless the investment is classified as held for sale (or included in a disposal group that is classified as held for sale).

2.4 Associates, joint ventures and joint arrangement

An associate is an entity in which the Group has significant influence, but not control or joint control, over its management, including participation in the financial and operating policy decisions.

A joint venture is an arrangement whereby the Group and other parties contractually agree to share control of the arrangement, and have rights to the net assets of the arrangement.

An investment in an associate or a joint venture is accounted for in the consolidated financial statements under the equity method, unless it is classified as held for sale (or included in a disposal group that is classified as held for sale). Under the equity method, the investment is initially recorded at cost, adjusted for any excess of the Group's share of the acquisition-date fair values of the investee's identifiable net assets over the cost of the investment (if any). The cost of the investment includes purchase price, other costs directly attributable to the acquisition of the investment, and any direct investment into the associate or joint venture that forms part of the Group's equity investment. Thereafter, the investment is adjusted for the post acquisition change in the Group's share of the investee's net assets and any impairment loss relating to the investment. The Group's share of the post-acquisition post-tax results of the investees and any impairment losses for the year are recognised in the consolidated statement of income, whereas the Group's share of the post-acquisition post-tax items of the investees' other comprehensive income is recognised as other comprehensive

income in the consolidated statement of comprehensive income.

When the Group's share of losses exceeds its interest in the associate or the joint venture, the Group's interest is reduced to nil and recognition of further losses is discontinued except to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of the investee. For this purpose, the Group's interest is the carrying amount of the investment under the equity method together with the Group's long-term interests that in substance form part of the Group's net investment in the associate or the joint venture (after applying the ECL model to such other long-term interests where applicable).

Unrealised profits and losses resulting from transactions between the Group and its associates and joint venture are eliminated to the extent of the Group's interest in the investee, except where unrealised losses provide evidence of an impairment of the asset transferred, in which case they are recognised immediately in profit or loss.

If an investment in an associate becomes an investment in a joint venture or vice versa, retained interest is not remeasured. Instead, the investment continues to be accounted for under the equity method.

In all other cases, when the Group ceases to have significant influence over an associate or joint control over a joint venture, it is accounted for as a disposal of the entire interest in that investee, with a resulting gain or loss being recognised in profit or loss. Any interest retained in that former investee at the date when significant influence or joint control is lost is recognised at fair value and this amount is regarded as the fair value on initial recognition of a financial asset.

A joint arrangement is an arrangement of which two or more parties have joint control. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control.

To better share the risks and rewards associated with the construction, operation and maintenance of the 5G network infrastructure, the Group entered into a framework agreement with China Telecom Corporation Limited ('China Telecom') to build, maintain and share one nationwide 5G access network infrastructure (the 'Cooperation Agreement'). In accordance with the Cooperation Agreement, each of the Group and China Telecom is responsible for the construction and maintenance of 5G network infrastructure in their respective designated regions, and bear the associated construction, maintenance and operating costs. Both parties have established a joint operation mechanism and key decisions including overall network planning, construction project commencement and completion acceptance and a unified standard on construction and maintenance services across all regions are subject to mutual agreement by both parties.

The Group has accounted for the arrangement as a joint operation that is not structured through a separate vehicle, and has recognised its share of assets, liabilities, revenues and expenses in accordance with the terms of the arrangement.

2.5 Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the Chief Operating Decision-Maker ('CODM'). The CODM, who is responsible for allocating resources and assessing performance of the operating segments regularly, has been identified as the Executive Directors of the Company that makes strategic decisions.

2.6 Foreign currency translation

(a) Functional and presentation currency

Items included in the financial statements of each of the Group's entities are measured using the currency of the primary economic environment in which the entities operate ('the functional currency'). The consolidated financial statements are presented in RMB, which is the Company's functional and presentation currency.

(b) Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuation where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the statement of income.

(c) Group companies

The results and financial position of all the Group entities (none of which has the currency of a hyperinflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

Assets and liabilities for each statement of financial position presented are translated at the closing rate at the statement of financial position date;

Income and expenses for each statement of income are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the dates of the transactions); and

All resulting exchange differences are recognised in other comprehensive income and as a separate component of equity into other reserve.

On consolidation, exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are taken to shareholders' equity. When a foreign operation is sold, such exchange differences are recognised in the statement of income as part of the gain or loss on disposal.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.7 Property, plant and equipment (a) Construction-in-progress

Construction-in-progress ('CIP') represents buildings, plant and equipment under construction and pending installation, and is stated at cost less accumulated impairment losses. Costs include construction and acquisition costs, and interest charges arising from borrowings used to finance the assets during the construction period. No provision for depreciation is made on CIP until such time as the assets are completed and ready for its intended use. When the asset being constructed becomes available for use, the CIP is transferred to the appropriate category of assets.

(b) Property, plant and equipment

Property, plant and equipment held by the Group are stated at cost less accumulated depreciation and accumulated impairment losses, and are depreciated over their expected useful lives.

Property, plant and equipment comprise buildings, telecommunications equipment, leasehold improvements, office furniture, fixtures, motor vehicles and other equipment. The cost of an asset, except for those acquired in exchange for a non-monetary asset or assets, comprises its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use.

If an item of property, plant and equipment is acquired in exchange for another item of property, plant and equipment, the cost of such an item of property, plant and equipment is measured at fair value unless (i) the exchange transactions lacks commercial substance or (ii) the fair value of neither the asset received nor the asset given up is reliably measurable. If the acquired item is not measured at fair value, its cost is measured at the carrying amount of the asset given up.

Subsequent costs are included in the asset's carrying amount or recognised as a separate asset, as appropriate, only when it is probable at the time the costs are incurred that future economic benefits associated with the item will flow to the Group, and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognised. All other repairs and maintenance are charged to the statement of income during the financial period in which they are incurred.

(c) Depreciation

Depreciation on property, plant and equipment is calculated using the straight-line method to allocate their costs less their residual values over their estimated useful lives, as follows:

Depreciable life Residual rate

Buildings 10-30 years 3-5% Telecommunications equipment 5-10 years 3-5% Office furniture, fixtures, motor vehicles and other equipment 5-10 years 3-5%

Leasehold improvements are depreciated over the shorter of their estimated useful lives and the lease periods.

The assets' residual values and useful lives are reviewed, and adjusted if appropriate, at each statement of financial position date.

An asset's carrying amount is written down immediately to its recoverable amount if the asset's carrying amount is greater than its estimated recoverable amount (Note 2.13).

2.7 Property, plant and equipment (Continued)

(d) Gain or loss on disposal of property, plant or equipment

Gains or losses on disposal of property, plant or equipment are determined by comparing the net sales proceeds with the carrying amounts, and are recognised in the statement of income.

2.8 Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the Group's share of the net identifiable assets of the acquired subsidiaries at the date of acquisition. Goodwill is tested at least annually for impairment and carried at cost less accumulated impairment losses. Impairment losses on goodwill are not reversed. Gain or loss on the disposal of an entity includes the carrying amount of goodwill relating to the entity sold.

Goodwill is allocated to cash-generating units for the purpose of impairment testing. The allocation is made to those cash-generating units or groups of cash-generating units that are expected to benefit from the synergies of business combination in which the goodwill arose.

2.9 Contract costs

Contract costs are either the incremental costs of obtaining a contract with a customer or the costs to fulfil a contract with a customer which are not capitalised as inventory (see Note 2.15), property, plant and equipment (see Note 2.7) or intangible assets.

Incremental costs of obtaining a contract are those costs that the Group incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained e.g. an incremental sales commission. Incremental costs of obtaining a contract are capitalised when incurred if the costs are expected to be recovered, unless the expected amortisation period is one year or less from the date of initial recognition of the asset, in which case the costs are expensed when incurred. Other costs of obtaining a contract are expensed when incurred.

Costs to fulfil a contract are capitalised if the costs relate directly to an existing contract or to a specifically identifiable anticipated contract; generate or enhance resources that will be used to provide goods or services in the future; and are expected to be recovered. Costs that relate directly to an existing contract or to a specifically identifiable anticipated contract may include direct labour, direct materials, allocations of costs, costs that are explicitly chargeable to the customer and other costs that are incurred only because the Group entered into the contract. Other costs of fulfilling a contract, which are not capitalised as inventory, property, plant and equipment or intangible assets, are expensed as incurred.

Capitalised contract costs are stated at cost less accumulated amortisation and impairment losses. Impairment losses are recognised to the extent that the carrying amount of the contract cost asset exceeds the net of (i) remaining amount of consideration that the Group expects to receive in exchange for the goods or services to which the asset relates, less (ii) any costs that relate directly to providing those goods or services that have not yet been recognised as expenses.

Amortisation of capitalised contract costs is charged to profit or loss when the revenue to which the asset relates is recognised. The accounting policy for revenue recognition is set out in Note 2.25.

2.10 Contract assets and contract liabilities

A contract asset is recognised when the Group recognises revenue (see Note 2.25) before being unconditionally entitled to the consideration under the payment terms set out in the contract. Contract assets are assessed for expected credit loss ('ECL') in accordance with the policy set out in Note 2.14 and are reclassified to receivables when the right to the consideration has become

unconditional (see Note 2.16).

A contract liability is recognised when the customer pays non-refundable consideration before the Group recognises the related revenue (see Note 2.25). A contract liability would also be recognised if the Group has an unconditional right to receive non-refundable consideration before the Group recognises the related revenue. In such cases, a corresponding receivable would also be recognised (see Note 2.16).

The Group provides subscriber points reward program, the transaction price of providing telecommunications services and the subscriber points reward is allocated based on their standalone price. The allocated portion of transaction price for the subscriber points reward is recorded as contract liability when the rewards are granted and recognised as revenue when the points are redeemed or expired.

For a single contract with the customer, either a net contract asset or a net contract liability is presented. For multiple contracts, contract assets and contract liabilities of unrelated contracts are not presented on a net basis.

When the contract includes a significant financing component, the contract balance includes interest accrued under the effective interest method (see Note 2.25).

2.11 Other assets

Other assets mainly represent (i) computer software; (ii) prepaid usage fees for transmission lines and electricity cables.

(i) Acquired computer software licences are capitalised on the basis of the costs incurred to acquire and bring to use the specific software. These costs are amortised over their estimated useful lives on a straight-line basis.

(ii) Long-term prepaid usage fees for transmission lines and electricity cables are amortised using a straight-line method over service period.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.12 Financial assets

The Group classifies its financial assets into two measurement categories: those measured at amortised cost and those measured at fair value. The determination is made at initial recognition and the classification depends on the entity's business model for managing

its financial instruments and the contractual cash flow characteristics of the instrument.

Financial assets measured at amortised cost

Financial assets are classified under this category if they satisfy both of the following conditions:

The assets are held within a business model whose objective is to hold assets in order to collect contractual cash flows for managing liquidity and generating income on the financial assets, but not for the purpose of realising fair value gains; and

The contractual terms of the financial assets give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding, with interest being the consideration for the time value of money and for the credit risk associated with the principal amount outstanding during a particular period of time.

Cash and cash equivalents, short-term bank deposits and restricted deposits, accounts receivable, prepayments and other current assets, amounts due from ultimate holding company, amounts due from related parties, amounts due from domestic carriers and certain other assets are classified under this category.

Financial assets under this category are carried at amortised cost using effective interest method less provision for impairment. Gains and losses arising from disposal, being the differences between the net sales proceeds and the carrying values, are recognised in the statement of income. Interest income is recognised in the statement of income using the effective interest method and disclosed as interest income.

Financial assets measured at fair value

Investments and other financial assets are classified under this category if they do not meet the conditions to be measured at amortised cost. Financial assets under this category are debt and equity investments carried at fair value.

Debt investments are classified as fair value through other comprehensive income ('FVOCI') (recycling), if the contractual cash flows of the investment comprise solely payments of principal and interest and the investment is held within a business model whose objective is achieved by both the collection of contractual cash flows and sale. Changes in fair value are recognised in other comprehensive income, except for the recognition in profit or loss of ECLs, interest income (calculated using the effective interest method) and foreign exchange gains and losses. When the investment is derecognised, the amount accumulated in other comprehensive income is recycled from equity to profit or loss.

An investment in equity securities is classified as fair value through profit and loss ('FVPL') unless the equity investment is not held for trading purposes and on initial recognition of the investment the Group makes an irrevocable election to designate the investment at FVOCI (non-recycling) such that subsequent changes in fair value are recognised in other comprehensive income. Such irrevocable elections are made on an instrument-by-instrument basis at the time of initial recognition, but may only be made if the investment meets the definition of equity from the issuer's perspective. Where such an election is made, the amount accumulated in other comprehensive income remains in the fair value reserve (non-recycling) until the investment is disposed of. At the time of disposal, the amount accumulated in the fair value reserve (non-recycling) is transferred to retained profits. It is not recycled through profit or loss. Dividends from an investment in equity securities, irrespective of whether classified as at FVPL or FVOCI, are recognised in profit or loss as other income in accordance with the policy set out in note 2.27.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.13 Impairment of non-financial assets

Assets that have an indefinite useful life or are not yet available for use are not subject to amortisation and are tested for impairment at each statement of financial position date. Assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised for the amount by which the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of (i) an asset's fair value less costs to sell and (ii) value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Assets other than goodwill that impairment losses were previously recognised are reviewed for possible reversal of the impairment at each reporting date.

2.14 Credit losses from financial instruments and contract assets

The Group recognises a loss allowance for ECLs on the following items:

- financial assets measured at amortised cost (including cash and cash equivalents, short-term bank deposits and restricted deposits, accounts receivable, prepayments and other current assets, amounts due from ultimate holding company, amounts due from related parties, amounts due from domestic carriers and certain other assets);

- contract assets as defined in IFRS/HKFRS 15, 'Revenue from contracts with customers' ('IFRS/HKFRS 15') (see Note 2.10); and

- debt securities measured at FVOCI (recycling).

Financial assets measured at fair value, including financial assets measured at FVPL and financial assets measured at FVOCI (non-recycling), are not subject to the ECL assessment.

Measurement of ECLs

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

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

In measuring ECLs, the Group takes into account reasonable and supportable information that is available without undue cost or effort. This includes information about past events, current conditions and forecasts of future economic conditions.

ECLs are measured on either of the following bases:

- twelve-month ECLs: these are losses that are expected to result from possible default events within the twelve months after the reporting date; and

- lifetime ECLs: these are losses that are expected to result from all possible default events over the expected lives of the items to which the ECL model applies.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.14 Credit losses from financial instruments and contract assets (Continued) Measurement of ECLs (Continued)

Loss allowances for accounts receivable and contract assets are always measured at an amount equal to lifetime ECLs. ECLs on these financial assets are estimated using a provision matrix based on the Group's historical credit loss experience, adjusted for factors that are specific to the debtors and an assessment of both the current and forecast general economic conditions at the reporting date.

For all other financial instruments, the Group recognises a loss allowance equal to twelve months ECLs unless there has been a significant increase in credit risk of the financial instrument since initial recognition, in which case the loss allowance is measured at an amount equal to lifetime ECLs.

Significant increases in credit risk

In assessing whether the credit risk of a financial instrument has increased significantly since initial recognition, the Group compares the risk of default occurring on the financial instrument assessed at the reporting date with that assessed at the date of initial recognition. The Group considers both quantitative and qualitative information that is reasonable and supportable, including historical experience and forward-looking information that is available without undue cost or effort.

In particular, the following information is taken into account when assessing whether credit risk has increased significantly since initial recognition:

- failure to make payments of principal or interest on their contractually due dates;

- an actual or expected significant deterioration in a financial instrument's external or internal credit rating (if available);

- an actual or expected significant deterioration in the operating results of the debtor; and

- existing or forecast changes in the technological, market, economic or legal environment that have a significant adverse effect on the debtor's ability to meet its obligation to the Group.

Depending on the nature of the financial instruments, the assessment of a significant increase in credit risk is performed on either an individual basis or a collective basis. When the assessment is performed on a collective basis, the financial instruments are grouped based on shared credit risk characteristics, such as past due status and credit risk ratings.

ECLs are remeasured at each reporting date to reflect changes in the financial instrument's credit risk since initial recognition. Any change in the ECL amount is recognised as an impairment gain or loss in profit or loss. The Group recognises an impairment gain or loss for all financial instruments with a corresponding adjustment to their carrying amount through a loss allowance account.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.14 Credit losses from financial instruments and contract assets (Continued) Credit-impaired financial assets

At each reporting date, the Group assesses whether a financial asset is credit-impaired. A financial asset is credit-impaired when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Evidence that a financial asset is credit-impaired includes the following observable events:

- significant financial difficulties of the debtor;

- a breach of contract, such as a default or delinquency in interest or principal payments;

- it becoming probable that the borrower will enter into bankruptcy or other financial reorganisation;

- significant changes in the technological, market, economic or legal environment that have an adverse effect on the debtor; or

- the disappearance of an active market for a security because of financial difficulties of the issuer.

Write-off policy

The gross carrying amount of a financial asset or contract asset is written off (either partially or in full) to the extent that there is no realistic prospect of recovery. This is generally the case when the Group determines that the debtor does not have assets or sources of income that could generate sufficient cash flows to repay the amounts subject to the write-off.

Subsequent recoveries of an asset that was previously written off are recognised as a reversal of impairment in profit or loss in the period in which the recovery occurs.

2.15 Inventories and consumables

Inventories, which primarily comprise handsets, SIM/USIM cards and accessories, are stated at the lower of cost and net realisable value. Cost is based on the first-in-first-out method and comprises all costs of purchase and other costs incurred in bringing the inventories to their present location and condition. Net realisable value for all the inventories is determined on the basis of anticipated sales proceeds less estimated costs necessary to make the sale.

Consumables consist of materials and supplies used in maintaining the Group's telecommunications networks and are charged to the statement of income when brought into use. Consumables are stated at cost less any provision for obsolescence.

2.16 Accounts receivable

A receivable is recognised when the Group has an unconditional right to receive consideration. A right to receive consideration is unconditional if only the passage of time is required before payment of that consideration is due. If revenue has been recognised before the Group has an unconditional right to receive consideration, the amount is presented as a contract asset (see Note

2.10).

Receivables are stated at amortised cost using the effective interest method less allowance for credit losses (see Note 2.14).

2.17 Short-term bank deposits and restricted deposits

Short-term bank deposits are cash invested in fixed-term deposits with original maturities ranging from more than three months to one year.

Restricted deposits mainly included statutory reserve deposits with the People's Bank of China ('PBOC') placed by Finance Company.

2.18 Cash and cash equivalents

Cash and cash equivalents include cash in hand, deposits held at call with banks and other short-term highly liquid investments with original maturities of three months or less.

2.19 Government grants

Government grants are recognised in the statement of financial position initially when there is reasonable assurance that they will be received and that the Group will comply with the conditions attaching to them. Grants that compensate the Group for expenses incurred are recognised as income in profit or loss on a systematic basis in the same period in which the expenses are incurred. Grants that compensate the Group for the cost of an asset are recognised as deferred revenue consequently are effectively recognised in profit or loss over the useful life of the asset as other income.

2.20 Borrowings

Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost, any difference between the proceeds (net of transaction costs) and the redemption value is recognised in the statement of income over the period of the borrowings using the effective interest method.

Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least twelve months after the statement of financial position date.

2.21 Share capital

Ordinary shares are classified as equity.

Incremental costs directly attributable to the issuance of new shares or options are shown in equity as a deduction, net of tax, from the proceeds.

Where any group company purchases the Company's equity share capital (treasury shares), the consideration paid, including any directly attributable incremental costs (net of tax) is deducted from equity attributable to equity shareholders of the Company and no gain or loss shall be recognised in the statement of income.

2.22 Employee benefits

(a) Retirement benefits

The Group participates in defined contribution pension schemes. For defined contribution plans, the Group pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The contributions are recognised as employee benefit expenses when they are due. Prepaid contributions are recognised as an asset to the extent that a reduction in the future payments is available.

2.22 Employee benefits (Continued) (b) Medical insurance

The Group's contributions to basic and supplementary medical insurances are expensed as incurred. The Group has no further payment obligations once the contributions have been paid.

(c) Housing benefits

One-off cash housing subsidies paid to PRC employees are charged to the statement of income in the year in which it is determined that the payment of such subsidies is probable and the amounts can be reasonably estimated.

The Group's contributions to the housing fund, special monetary housing benefits and other housing benefits are expensed as incurred. The Group has no further payment obligations once the contributions have been paid.

(d) Supplementary benefits

In addition to participating in local governmental defined contribution social insurance, subsidiaries of the Group also provide other post retirement supplementary benefits to their employees, including supplementary pension allowance, reimbursement of medical expenses and supplementary medical insurance. These post retirement supplementary benefits are accounted as defined benefit plan. The present value of the defined benefit obligation is included in non-current other obligations and salary and welfare payables (current portion). The liability is remeasured every three months and the remeasurement is recognised in other comprehensive income, which is not allowed to reverse to profit and loss in subsequent period. As at 31 December 2020, the amount of the liability was RMB75 million (2019: RMB70 million).

(e) Share-based compensation costs

The Group operates an equity-settled, share-based compensation plan. The fair value of the employee services received in exchange for the grant of the share options is recognised as an expense. The total amount to be expensed over the vesting period is determined by reference to the fair value of the share options granted at the grant date excluding the impact of any non-market vesting conditions (for example, revenue and profit targets) and is not subsequently remeasured. However, non-market vesting conditions are considered in determining the number of options that are expected to vest. At each statement of financial position date, the Group revises its estimates of the number of share options that are expected to vest. The Group recognises the impact of the revision of original estimates, if any, in the statement of income of the period in which the revision occurs, with a corresponding adjustment to equity.

The equity amount is recognised in the employee share-based compensation reserve until either the option is exercised (when it is included in the amount recognised in share capital for the shares issued) or the option expires (when it is released directly to retained profits).

(f) Restricted A-Share Incentive Scheme

Restricted shares granted by A-Share Company to the employees of the Group is treated as a capital contribution. The fair value of the core employee services received in exchange for the grant of the restricted shares is recognised as an expense over the vesting period, with a corresponding credit to equity. The total amount to be expensed is determined by reference to the fair value of the granted shares measured as of the grant date less the subscription price.

At the end of each reporting period, the Group revises its estimates of the number of restricted shares that are expected to be vested. The impact of the revision of the original estimates, if any, is recognised in profit or loss, with a corresponding adjustment to equity.

2.23 Accounts payable

Accounts payable are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Accounts payable are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.

Accounts payable are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method.

2.24 Provisions

Provisions are recognised when the Group has present legal or constructive obligations as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount has been reliably estimated. Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by considering the class of obligations as a whole. A provision is recognised even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small.

Provisions are measured at the present value of the pre-tax amount of expenditures expected to be required to settle the obligation that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognised as interest expense.

2.25 Revenue recognition

Income is classified by the Group as revenue when it arises from the provision of services and the sale of goods in the ordinary course of the Group's business.

Revenue is recognised when control over a product or service is transferred to the customer at the amount of promised consideration to which the Group is expected to be entitled, excluding those amounts collected on behalf of third parties. Revenue excludes value added tax or other sales taxes and is after deduction of any trade discounts.

Where the contract contains a financing component which provides a significant financing benefit to the customer for more than twelve months, revenue is measured at the present value of the amount receivable, discounted using the discount rate that would be reflected in a separate financing transaction with the customer, and interest income is accrued separately under the effective interest method. Where the contract contains a financing component which provides a significant financing benefit to the Group, revenue recognised under that contract includes the interest expense accreted on the contract liability under the effective interest method. The Group takes advantage of the practical expedient in IFRS/HKFRS 15 and does not adjust the consideration for any effects of a significant financing component if the period of financing is twelve months or less.

Further details of the Group's revenue recognition policies are as follows:

• Voice usage and monthly fees are recognised when the services are rendered;

• Revenue from the provision of broadband and mobile data services are recognised when the services are provided to customers;

• Data and internet application service revenue, which mainly represent revenue from the provision of data storage and application, information communications technology and other internet related services, are recognised upon fulfillment of services obligation;

2.25 Revenue recognition (Continued)

• Other value-added services revenue, which mainly represents revenue from the provision of services such as short message, cool ringtone, personalised ring, caller number display and secretarial services to subscribers etc., are recognised when services are rendered;

• Interconnection fees, which represent revenue from other domestic and foreign telecommunications operators for the use of the Group's telecommunications network, are recognised when services are rendered;

• Revenue from transmission lines usage and associated services, which mainly represent income from offering transmission lines and customer-end equipment to customers for usage and related services, are recognised upon fulfillment of services obligation over the respective usage and service period;

• Standalone sales of telecommunications products, which mainly represent handsets and accessories, and telecommunications equipment, are recognised when title have been passed to the buyers;

• The Group offers preferential packages to customers which include bundle sale of mobile handsets and provision of services. The total contract consideration of such preferential packages is allocated to service revenue and sales of handsets based on their standalone

selling prices. Revenue relating to the sale of handset is recognised when the title is passed to the customer whereas service revenue is recognised based upon the actual usage of telecommunications services. The cost of the mobile handset is expensed immediately to the statement of income upon revenue recognition.

In general, revenue from rendering of telecommunication services are recognised over-time during the period of fulfillment of services obligation, whereas revenue from sales of handsets and other telecommunications equipment, in case they are treated as separate performance obligations, are recognised at a point in time.

2.26 Interest income

Interest income from deposits in banks or other financial institutions is recognised on a time proportion basis, using the effective interest method. For financial assets measured at amortised cost that are not credit-impaired, the effective interest rate is applied to the gross carrying amount of the asset. For credit impaired financial assets, the effective interest rate is applied to the amortised cost of the asset.

2.27 Dividend income

Dividend income is recognised when the right to receive payment is established.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.28 Leased assets

At inception of a contract, the Group assesses whether the contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control is conveyed where the customer has both the right to direct the use of the identified asset and to obtain substantially all of the economic benefits from that use.

(a) As a lessee

At inception or on reassessment of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease and non-lease component on the basis of their relative stand-alone prices.

At the lease commencement date, the Group recognises a right-of-use asset and a lease liability, except for short-term leases that have a lease term of 12 months or less and leases of low-value assets which, for the Group are primarily computers and office furniture. When the Group enters into a lease in respect of a low-value asset, the Group decides whether to capitalise the lease on a lease-by-lease basis. The lease payments associated with those leases which are not capitalised are recognised as an expense on a systematic basis over the lease term.

Where the lease is capitalised, the lease liability is initially recognised at the present value of the lease payments payable

over the lease term, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, using a relevant incremental borrowing rate. After initial recognition, the lease liability is measured at amortised cost and interest expense is calculated using the effective interest method. Variable lease payments that do not depend on an index or rate are not included in the measurement of the lease liability and hence are charged to profit or loss in the accounting period in which they are incurred.

The right-of-use asset recognised when a lease is capitalised is initially measured at cost, which comprises the initial amount of the lease liability plus any lease payments made at or before the commencement date, and any initial direct costs incurred. Where applicable, the cost of the right-of-use assets also includes an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, discounted to their present value, less any lease incentives received. The right-of-use asset is subsequently stated at cost less accumulated depreciation and impairment losses (see Note 2.13). Right-of-use assets are subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the unexpired term of lease. The estimated useful lives of right-of-use assets are determined on the same basis as those of property and equipment.

The lease liability is remeasured when there is a change in future lease payments arising from a change in an index or rate, or there is a change in the Group's estimate of the amount expected to be payable under a residual value guarantee, or there is a change arising from the reassessment of whether the Group will be reasonably certain to exercise a purchase, extension or termination option. When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.

2.28 Leased assets (Continued) (a) As a lessee (Continued)

The lease liability is also remeasured when there is a change in the scope of a lease or the consideration for a lease that is not originally provided for in the lease contract ('lease modification') that is not accounted for as a separate lease. In this case the lease liability is remeasured based on the revised lease payments and lease term using a revised discount rate at the effective date of the modification.

In the consolidated statement of financial position, the current portion of long-term lease liabilities is determined as the present value of contractual payments that are due to be settled within twelve months after the reporting period.

The Group presents right-of-use assets that do not meet the definition of investment property, and lease liabilities separately in the consolidated statement of financial position.

(b) As a lessor

When the Group acts as a lessor, it determines at lease inception whether each lease is a finance lease or an operating lease. A lease is classified as a finance lease if it transfers substantially all the risks and rewards incidental to the ownership of an underlying assets to the lessee. If this is not the case, the lease is classified as an operating lease.

When a contract contains lease and non-lease components, the Group allocates the consideration in the contract to each component on a relative stand-alone selling price basis. The rental income from operating leases is recognised in profit or loss in equal instalments over the periods covered by the lease term, except where an alternative basis is more representative of the pattern of benefits to be derived from the use of the leased asset. Lease incentives granted are recognised in profit or loss as an integral part of the aggregate net lease payments receivable. Variable lease payments that do not depend on an index or a rate are recognised as income in the accounting period in which they are earned.

When the Group is an intermediate lessor, the sub-leases are classified as a finance lease or as an operating lease with reference to the right-of-use asset arising from the head lease. If the head lease is a short-term lease to which the Group applies the exemption described in Note 2.28(a), then the Group classifies the sub-lease as an operating lease.

2.29 Borrowing costs

Borrowing costs are expensed as incurred, except for interest 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, in which case they are capitalised as part of the cost of that asset. Capitalisation of borrowing costs commences when expenditures for the asset and borrowing costs are being incurred and the activities to prepare the asset for its intended use are in progress. Borrowing costs are capitalised up to the date when the project is completed and ready for its intended use.

To the extent that funds are borrowed specifically for the purpose of obtaining a qualifying asset, the amount of borrowing costs eligible for capitalisation is determined at the actual borrowing costs incurred on that borrowing during the period less any investment income on the temporary investment of those borrowings.

To the extent that funds are borrowed generally and used for the purpose of obtaining a qualifying asset, the amount of borrowing costs eligible for capitalisation is determined by applying a capitalisation rate to the expenditures on that asset. The capitalisation rate is the weighted average of the borrowing costs applicable to the borrowings of the Group that are outstanding during the period, other than borrowings made specifically for the purpose of obtaining a qualifying asset. The amount of borrowing costs capitalised during a period should not exceed the amount of borrowing cost incurred during that period. Other borrowing costs are recognised as expenses when incurred.

2.30 Taxation

(a) Current income tax

The current income tax charge is calculated on the basis of the tax laws enacted or substantially enacted at the statement of financial position date in the countries where the Company and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and establishes provisions where appropriate on the basis of the amount expected to be paid to the tax authorities.

(b) Deferred income tax

Deferred tax assets and liabilities arise from deductible and taxable temporary differences respectively, being the differences between the carrying amounts of assets and liabilities for financial reporting purposes and their tax bases. Deferred tax assets also arise from unused tax losses and unused tax credits.

Apart from certain limited exceptions, all deferred tax liabilities, and all deferred tax assets to the extent that it is probable that future taxable profits will be available against which the asset can be utilised, are recognised. Future taxable profits that may support the recognition of deferred tax assets arising from deductible temporary differences include those that will arise from the reversal of existing taxable temporary differences, provided those differences relate to the same taxation authority and the same taxable entity, and are expected to reverse either in the same period as the expected reversal of the deductible temporary difference or in periods into which a tax loss arising from the deferred tax asset can be carried back or forward. The same criteria are adopted when determining whether existing taxable temporary differences support the recognition of deferred tax assets arising from unused tax losses and credits, that is, those differences are taken into account if they relate to the same taxation authority and the same taxable entity, and are expected to reverse in a period, or periods, in which the tax loss or credit can be utilised.

The limited exceptions to recognition of deferred tax assets and liabilities are those temporary differences arising from goodwill not deductible for tax purposes, the initial recognition of assets or liabilities that affect neither accounting nor taxable profit (provided they are not part of a business combination), and temporary differences relating to investments in subsidiaries to the extent that, in the case of taxable differences, the Group controls the timing of the reversal and it is probable that the differences will not reverse in the foreseeable future, or in the case of deductible differences, unless it is probable that they will reverse in the future.

The carrying amount of a deferred tax asset is reviewed at the end of each reporting period and is reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow the related tax benefit to be utilised. Any such reduction is reversed to the extent that it becomes probable that sufficient taxable profits will be available.

2.31 Dividend distribution

Dividend distribution to the Company's shareholders is recognised as a liability in the Company's financial statements in the period in which the dividends are approved by the Company's shareholders.

2.32 Contingent liabilities and contingent assets

A contingent liability is a possible obligation that arises from past events and whose existence will only be confirmed by the occurrence or non-occurrence of one or more uncertain future events not wholly within the control of the Group. It can also be a present obligation arising from past events that is not recognised because it is not probable that outflow of economic resources will be required or the amount of obligation cannot be measured reliably.

A contingent liability is not recognised but is disclosed in the notes to the financial statements. When a change in the probability of an outflow of economic resources occurs so that outflow is probable, the liability will then be recognised as a provision.

A contingent asset is a possible asset that arises from past events and whose existence will be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not wholly within the control of the Group.

A contingent asset is not recognised but is disclosed in the notes to the financial statements when an inflow of economic benefits is probable. When an inflow is virtually certain, an asset is recognised.

2.33 Earnings per Share

Basic earnings per share is computed by dividing the profit attributable to equity shareholders of the Company by the weighted average number of ordinary shares outstanding during the year.

Diluted earnings per share is computed by dividing the profit attributable to equity shareholders of the Company by the weighted average number of ordinary shares outstanding during the year, after adjusting for the effects of the dilutive potential ordinary shares.

2.34 Related parties

(a) A person, or a close member of that person's family, is related to the Group if that person: (i) has control or joint control over the Group; (ii) has significant influence over the Group; or (iii) is a member of the key management personnel of the Group or the Group's parent. (b) An entity is related to the Group if any of the following conditions applies:

(i) The entity and the Group are members of the same group (which means that each parent, subsidiary and fellow subsidiary is related to the others);

(ii) One entity is an associate or joint venture of the other entity (or an associate or joint venture of a member of a group of which the other entity is a member);

(iii) Both entities are joint ventures of the same third party;

(iv) One entity is a joint venture of a third entity and the other entity is an associate of the third entity;

3. FINANCIAL RISK MANAGEMENT AND FAIR VALUES OF FINANCIAL INSTRUMENTS

3.1 Financial risk factors

The Group's operating activities expose it to a variety of financial risks: market risk (including foreign currency risk, price risk, cash flow and fair value interest rate risk), credit risk and liquidity risk. The Group's overall risk management program focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the Group's financial performance.

Financial risk management is carried out by the Group's headquarter, following the overall direction determined by the Executive Directors of the Company. The Group's headquarter identifies and evaluates financial risks in close co-operation with the Group's operating units.

(a) Market risk

(i) Foreign exchange risk

The Group's major operational activities are carried out in Mainland China and a majority of the transactions are denominated in RMB. The Group is exposed to foreign exchange risk arising from various currency exposures, primarily with respect to US dollars, HK dollars and Euro. Exchange risk mainly exists with respect to the balances with international carriers, cash and cash equivalents and financial assets denominated in foreign currencies.

The Group's headquarter is responsible for monitoring the amount of monetary assets and liabilities denominated in foreign currencies. From time to time, the Group may consider entering into forward exchange contracts or currency swap contracts to mitigate the foreign exchange risk. During the years of 2020 and 2019, the Group had not entered into any forward exchange contracts or currency swap contracts.

3. FINANCIAL RISK MANAGEMENT AND FAIR VALUES OF FINANCIAL INSTRUMENTS (Continued)

3.1 Financial risk factors (Continued) (a) Market risk (Continued)

(i) Foreign exchange risk (Continued)

The Group did not have and does not believe it will have any difficulties in exchanging its foreign currency cash into RMB at the exchange rates quoted by the PBOC.

As at 31 December 2020, if the RMB had strengthened/weakened by 10% against foreign currencies, primarily with respect to US dollars, HK dollars, Euro, Japanese Yen, SGD and AUD, while all other variables are held constant, the effect on profit after tax would be approximately RMB268 million (2019: approximately RMB170 million) for cash and cash equivalents, borrowings, accounts receivable and accounts payable denominated in foreign currencies, and the effect on other comprehensive income would be approximately RMB167 million (2019: approximately RMB313 million) for financial assets denominated in foreign currency, which were recorded in fair value through other comprehensive income.

(ii) Price risk

The Group is exposed to equity securities price risk because investments held by the Group are classified in the consolidated statement of financial position as financial assets measured at FVOCI.

The financial assets measured at FVOCI comprise primarily equity securities of Telefónica S.A. ('Telefónica'). As at

31 December 2020, if the share price of Telefónica had increased/decreased by 10%, while the exchange rate of RMB against Euro is held constant, the effect on other comprehensive income, would be approximately RMB167 million (2019: approximately RMB313 million).

(iii) Cash flow and fair value interest rate risk

The Group's interest-bearing assets are mainly represented by bank deposits and debt securities measured at FVOCI (recycling). Management does not expect the changes in market deposit interest rates will have significant impact on the financial statements as the deposits are all short-term in nature and the interest involved will not be significant.

The Group's interest rate risk mainly arises from interest-bearing borrowings including bank loans, commercial papers, promissory notes, corporate bonds, related parties loans and lease liabilities. Borrowings issued at floating rates expose the Group to cash flow interest rate risk. Borrowings issued at fixed rates expose the Group to fair value interest rate risk upon renewal. The Group determines the amount of its fixed rate or floating rate borrowings depending on the prevailing market conditions. During the years of 2020 and 2019, the Group's borrowings were mainly at fixed rates and were mainly denominated in RMB.

Increases in interest rates will increase the cost of new borrowing and the interest expense with respect to the Group's outstanding floating rate borrowings, and therefore could have a material adverse effect on the Group's financial position. Management continuously monitors the interest rate position of the Group and makes decisions with reference to the latest market conditions. From time to time, the Group may enter into interest rate swap agreements to mitigate its exposure to interest rate risks in connection with the floating rate borrowings, although the Group did not consider it was necessary to do so in the years of 2020 and 2019.

3.1 Financial risk factors (Continued) (a) Market risk (Continued)

(iii) Cash flow and fair value interest rate risk (Continued)

As at 31 December 2020, the Group had approximately RMB12,910 million (2019: approximately RMB19,496 million) of floating rate borrowings and short-term fixed rate borrowings and approximately RMB37,900 million (2019: approximately RMB42,669 million) of long-term fixed rate borrowings and lease liabilities.

For the year ended 31 December 2020, if interest rates on the floating rate borrowings and short-term fixed rate borrowings had increased/decreased 50 basic points while all other variables are held constant, the effect on profit after tax is approximately RMB48 million (2019: approximately RMB73 million).

(b) Credit risk

Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in a financial loss to the Group. Credit risk is managed on a group basis. Credit risk arises from cash and cash equivalents and short-term bank deposits with banks, as well as credit exposures to major corporate customers, individual subscribers and general corporate customers, related parties and other operators.

To limit exposure to credit risk relating to cash and cash equivalents and short-term bank deposits, the Group primarily places cash and cash equivalents and short-term bank deposits only with large state-owned financial institutions in the PRC and other banks with acceptable credit ratings. Therefore, the Group expects that there is no significant credit risk and does not expect that there will be any significant losses from non-performance by these counterparties.

In addition, the Group has no significant concentrations of credit risk with respect to individual subscribers and corporate customers. The Group has policies to limit the credit exposure on receivables for services and sales of mobile handsets. The Group assesses the credit quality of all its customers and sets credit limits on them by taking into account their financial position, the availability of guarantee from third parties, their credit history and other factors such as current market conditions. The normal credit period granted by the Group to individual subscribers and general corporate customers is 30 days from the date of billing unless they meet certain specified credit assessment criteria. For major corporate customers, the credit period granted by the Group is based on the service contract terms, normally not exceeding 1 year. The utilisation of credit limits and settlement pattern of customers are regularly monitored by the Group. In respect of other receivables, individual credit evaluations are performed on all counterparties requiring credit over a certain amount. These evaluations focus on the counterparties' past history of making payments when due and current ability to pay, and take into account information specific to the counterparties as well as the economic environment in which the counterparties operates.

Credit risk relating to amounts due from related parties and other telecommunications operators is not considered to be

significant as these companies are reputable and their receivables are settled on a regular basis.

Prudent liquidity risk management includes maintaining sufficient cash and availability of funds including the raising of bank loans and issuance of commercial papers, promissory notes and corporate bonds. Due to the dynamic nature of the underlying business, the Group's headquarter maintains flexibility in funding through having adequate amount of cash and cash equivalents and utilising different sources of financing when necessary.

3.2 Capital risk management

The Group's objectives when managing capital are:

• To safeguard the Group's ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders.

• To support the Group's stability and growth.

• To provide capital for the purpose of strengthening the Group's risk management capability.

In order to maintain or adjust the capital structure, the Group reviews and manages its capital structure actively and regularly to ensure optimal capital structure and shareholder returns, taking into account the future capital requirements of the Group and capital efficiency, prevailing and projected profitability, projected operating cash flows, projected capital expenditures and projected strategic investment opportunities.

The Group monitors capital on the basis of the debt-to-capitalisation ratio. This ratio is calculated as interest-bearing debts over interest-bearing debts plus total equity. Interest-bearing debts represent commercial papers, short-term bank loans, long-term bank loans, promissory notes, corporate bonds, lease liabilities, and amounts due to related parties, as shown in the consolidated statement of financial position. The interest-bearing debts do not include balance of deposits received by Finance Company from Unicom Group and its subsidiaries and an associate of RMB5,112 million and of RMB58 million, respectively, as at 31 December 2020 (2019: RMB4,879 million and RMB8 million, respectively).

The Group's debt-to-capitalisation ratios are as follows:

Financial assets of the Group mainly include cash and cash equivalents, short-term bank deposits and restricted deposits, accounts receivable, prepayments and other current assets, contract assets, amounts due from ultimate holding company, related parties and domestic carriers, financial assets measured at fair value. Financial liabilities of the Group mainly include accounts payable and accrued liabilities, short-term bank loans, commercial papers, corporate bonds, promissory notes, long-term bank loans, other obligations and amounts due to ultimate holding company, related parties and domestic carriers.

(a) Financial assets measured at fair value

The table below analyses financial instruments carried at fair value, by valuation method. The different levels have been defined as follows:

• Level 1 valuation: unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date.

• Level 2 valuation: observable inputs which fail to meet Level 1, and not using significant unobservable inputs. Unobservable inputs for which market data are not available.

• Level 3 valuation: fair value measured using significant unobservable inputs.

3.3 Fair value estimation (Continued)

(a) Financial assets measured at fair value (Continued)

The fair value of financial instruments traded in active markets is based on quoted market prices at the statement of financial position date. A market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service, or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm's length basis. The quoted market price used for financial assets held by the Group is the current bid price. These instruments are included in level 1 and comprise primarily equity securities of Telefónica, debt securities issued by banks which are classified as financial assets measured at FVOCI and certain equity investments, investments in monetary funds and wealth management products which are classified as financial assets measured at FVPL.

During the years ended 31 December 2020 and 2019, there were no transfer between Level 1 and Level 2, or transfer into or out of Level 3. The Group's policy is to recognise transfers between levels of fair value hierarchy as at the end of the reporting

period in which they occur.

4. CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The Group makes estimates and assumptions concerning the future. The resulting accounting estimates may not be equal to the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below.

4.1 Depreciation on property, plant and equipment

Depreciation on the Group's property, plant and equipment is calculated using the straight-line method to allocate cost up to residual values over the estimated useful lives of the assets. The Group reviews the useful lives and residual values periodically to ensure that the method and rates of depreciation are consistent with the expected pattern of realisation of economic benefits from property, plant and equipment. The Group estimates the useful lives and residual values of property, plant and equipment based on historical experience, taking into account anticipated technological changes. If there are significant changes from previously estimated useful lives, the amount of depreciation expenses may change.

4.2 Impairment of Non-Financial Assets

The Group tests whether non-financial assets have suffered from any impairment, in accordance with the accounting policy stated in Note 2.13. The recoverable amount of an asset is the higher of its fair value less costs to sell and its value in use. Management estimates value in use based on estimated discounted pre-tax future cash flows of the cash generating unit at the lowest level to which the asset belongs. If there is any significant change in management's assumptions, including discount rates or growth rates in the future cash flow projection, the estimated recoverable amounts of the non-financial assets and the Group's results would be significantly affected. Such impairment losses are recognised in the statement of income. Accordingly, there will be an impact to the future results if there is a significant change in the recoverable amounts of the non-financial assets.

No significant impairment loss on property, plant and equipment was recognised for the years ended 31 December 2020 and 2019.

4.3 Allowance for ECLs

Management estimates ECL allowance on accounts receivable and contract assets using a provision matrix based on the Group's historical credit loss experience, and adjusted for factors that are specific to the debtors and an assessment of both the current and forecast general economic conditions at the reporting date. The Group monitored and reviewed the assumptions relating to ECL regularly. For the Group's detailed assessment of credit risk, please refer to Note 3.1(b).

5. SEGMENT INFORMATION

The Executive Directors of the Company have been identified as the CODM. Operating segments are identified on the basis of internal reports that the CODM reviews regularly in allocating resources to segments and in assessing their performances.

The CODM make resources allocation decisions based on internal management functions and assess the Group's business performance as one integrated business instead of by separate business lines or geographical regions. Accordingly, the Group has only one operating segment and therefore, no segment information is presented.

The Group primarily operates in Mainland China and accordingly, no geographic information is presented. No single customer accounted for 10 percent or more of the Group's revenue in all periods presented.

6. REVENUE

Revenue from telecommunications services are subject to Value-added tax ('VAT') and VAT rates applicable to various telecommunications services. The Ministry of Finance, the State Administration of Taxation ('SAT') and General Administration of Customs of the PRC jointly issued a notice dated 20 March 2019 which stipulates downward adjustments of VAT rate for basic telecommunications services from 10% to 9% and VAT rate for sales of telecommunications products from 16% to 13% from 1 April 2019. The VAT rate for value-added telecommunications services remains at 6%. Basic telecommunications services include business activities for the provision of voice services, and transmission lines usage and associated services etc. Value-added telecommunications services include business activities for the provision of short message service and multimedia message service, broadband and mobile data services, and data and internet application services etc. VAT is excluded from the revenue.

Include: Revenue from contracts with customers within the scope of IFRS/HKFRS 15 302,732 289,332 Revenue from other sources 1,106 1,183

The Group's revenue is primarily generated from the provision of voice usage, broadband and mobile data services, data and internet application services, other value-added services, transmission lines usage and associated services and sale of telecommunication products. The Group bills the majority of its customers based on a fixed rate and service volume each month, and then has a right to consideration from the customers. Transaction prices that were allocated to unsatisfied performance obligations as of the end of the reporting period are expected to be recognised within one to five years when services are rendered. The Group has applied the practical expedient in paragraph 121 of IFRS/HKFRS 15 and therefore the information about remaining performance obligations is not disclosed for contracts that have an original expected duration of one year or less and also for those performance obligations which are regarded as satisfied as invoiced.

The tax losses can be carried forward for five years from the year incurred and hence will be expired by the year of 2025.

However, the resulting revaluations of the prepayments for the leasehold land were not recognised under IFRSs/HKFRSs. Accordingly, deferred tax assets were recorded by the Group under IFRSs/HKFRSs.

(ii) According to 'Announcement on Enterprise Income Tax Policy for Those Enterprise Involved in the Accelerated Depreciation of Property, Plant and Equipment' (Caishui [2014] No.75) issued by the MOF and the SAT of the PRC, starting from 2014, the Group's property, plant and equipment that comply with this tax policy are allowed to be depreciated under the accelerated depreciation method, or fully deducted for tax purpose in the year of purchase. Temporary differences arise from the different useful lives under tax basis and accounting basis have been recorded as deferred tax liabilities.

14. EARNINGS PER SHARE

Basic earnings per share for the years ended 31 December 2020 and 2019 were computed by dividing the profit attributable to equity shareholders of the Company by the weighted average number of ordinary shares outstanding during the years.

Diluted earnings per share for the years ended 31 December 2020 and 2019 were computed by dividing the profit attributable to equity shareholders of the Company by the weighted average number of ordinary shares outstanding during the years, after adjusting for the effects of the dilutive potential ordinary shares.

17. GOODWILL

Goodwill arising from the acquisitions of Unicom New Century Telecommunications Co., Ltd. and Unicom New World Telecommunications Co., Ltd. by the Group in 2002 and 2003, respectively, represented the excess of the purchase consideration over the Group's shares of the fair values of the separately identifiable net assets acquired prior to the adoption of HKFRSs and AG 5 in 2005.

Goodwill is allocated to the Group's cash-generating units ('CGU'). The recoverable amount of goodwill is determined based on value in use calculations. These calculations use pre-tax cash flow projections for 5 years based on financial budgets approved by management, including service revenue annual growth rate of 1% (2019: 1%) and the applicable discount rate of 11% (2019: 11%). Management determined expected growth rates and operating results based on past performance and its expectations in relation to market developments. The discount rate used is pre-tax and reflects specific risks relating to the CGU. Based on management's assessment results, there was no impairment of goodwill as at 31 December 2020 and 2019, any reasonably possible change in the assumptions used in the calculation of recoverable amount would not result in impairment losses.

Accounts receivable 26,009 24,601 Less: Credit loss allowance (9,722) (7,368)

16,287 17,233

The gross carrying amount of accounts receivable from contracts with customers amounted to RMB25,933 million as at 31 December 2020 (2019: RMB24,569 million).

The aging analysis of accounts receivable, based on the billing date and net of credit loss allowance, is as follows:

2020 2019

Within one month 8,963 9,472 More than one month to three months 2,766 2,545 More than three months to one year 3,914 3,881 More than one year 644 1,335

16,287 17,233

The normal credit period granted by the Group to individual subscribers and general corporate customers is thirty days from the date of billing unless they meet certain specified credit assessment criteria. For major corporate customers, the credit period granted by the Group is based on the service contract terms, normally not exceeding one year.

There is no significant concentration of credit risk with respect to customers receivables, as the Group has a large number of customers. The Covid-19 pandemic since early 2020 has brought about additional uncertainties in the operations and financial position of the Group's customers. The Group considered the impact of Covid-19 when evaluating the forward-looking information used in the ECL model and reassessed expected loss provisions including assessing the risk factors associated with various customer sectors and applying an upward risk weighting to those sectors with a significant increase in credit risk.

27. ACCOUNTS RECEIVABLE (Continued)

The Group measures loss allowances for accounts receivable at an amount equal to lifetime ECLs, which is calculated using a provision matrix. As the Group's historical credit loss experience indicate that there are different loss patterns for different customer types, the loss allowance based on past due status is distinguished between the Group's different customer types.

The following table provides information about the Group's exposure to credit risk and ECLs for accounts receivable as at 31 December 2020:

31. RESERVES (Continued)

(b) Nature and purpose (i) Statutory reserves

CUCL is registered as a foreign investment enterprise in the PRC. In accordance with the Articles of Association, it is required to provide for certain statutory reserves, namely, general reserve fund and staff bonus and welfare fund, which are appropriated from profit after tax and non-controlling interests but before dividend distribution.

CUCL is required to allocate at least 10% of its profit after tax and non-controlling interests determined under the PRC Company Law to the general reserve fund until the cumulative amounts reach 50% of the registered capital. The statutory reserve can only be used, upon approval obtained from the relevant authority, to offset accumulated losses or increase capital.

Accordingly, CUCL appropriated approximately RMB1,246 million (2019: approximately RMB1,273 million) to the general reserve fund for the year ended 31 December 2020.

Appropriation to the staff bonus and welfare fund is made at the discretion of the Board of Directors. The staff bonus and welfare fund can only be used for special bonuses or the collective welfare of the employees and cannot be distributed as cash dividends. Under IFRS/HKFRSs, the appropriations to the staff bonus and welfare fund are charged to the statement of income as expenses incurred since any assets acquired through this fund belong to the employees. For the years ended

31 December 2020 and 2019, no appropriation to staff bonus and welfare fund has been made by CUCL.

According to the PRC tax approval document issued by the MOF and the SAT of the PRC, the upfront connection fees were not subject to the PRC enterprise income tax and an amount equal to the upfront connection fees recognised in the retained profits had been transferred from retained profits to the statutory reserve. As at 31 December 2011, an accumulated appropriation of approximately RMB12,289 million was made to the statutory reserve and no more upfront connection fees are recognised afterwards.

(ii) General risk reserve

CUCL and Unicom Group established the Finance Company to provide certain financial services. Pursuant to 'Requirements on Impairment Allowance for Financial Institutions' (Caijin [2012] No. 20) issued by the MOF which effective on 1 July 2012 (the 'Document'), the Finance Company establishes a general risk reserve within the shareholders' equity, through appropriation of retained profits, to address unidentified potential losses relating to risk assets. The general risk reserve balance should not be less than 1.5% of the ending balance of risk assets, as defined in the Document.

(iii) Investment revaluation reserve

The investment revaluation reserve represents the changes in fair value of financial assets through other comprehensive income, net of tax, until the financial assets are derecognised.

(iv) Other reserve

Other reserve mainly represents the difference between the consideration and the net assets value for business combination of entities and businesses under common control, the effect of CUCL's capitalisation of retained profits, and capital contribution relating to share-based payment borne by A Share Company.

32. DIVIDENDS

At the annual general meeting held on 25 May 2020, the shareholders of the Company approved the payment of a final dividend of RMB0.148 per ordinary share for the year ended 31 December 2019, totaling approximately RMB4,529 million which has been reflected as a reduction of retained profit for the year ended 31 December 2020.

At a meeting held on 11 March 2021, the Board of Directors of the Company proposed the payment of a final dividend of RMB0.164 per ordinary share to the shareholders for the year ended 31 December 2020 totaling approximately RMB5,018 million. This proposed dividend has not been reflected as a dividend payable in the consolidated financial statements as at 31 December 2020, but will be reflected in the consolidated financial statements for the year ending 31 December 2021.

2020 2019

Proposed final dividend:

RMB0.164 (2019: RMB0.148) per ordinary share by the Company 5,018 4,529

Pursuant to the PRC enterprise income tax law, a 10% withholding income tax is levied on dividends declared on or after 1 January 2008 by foreign investment enterprises to their foreign enterprise shareholders unless the enterprise investor is deemed as a PRC Tax Resident Enterprise ('TRE'). On 11 November 2010, the Company obtained an approval from the SAT of the PRC, pursuant to which the Company qualifies as a PRC TRE from 1 January 2008. Therefore, as at 31 December 2020, the Company's subsidiaries in the PRC did not accrue for withholding tax on dividends distributed to the Company and there has been no deferred tax liability accrued in the Group's consolidated financial statements for the undistributed profits of the Company's subsidiaries in the PRC.

For the Company's non-PRC TRE shareholders (including HKSCC Nominees Limited), the Company would distribute dividends after deducting the amount of enterprise income tax payable by these non-PRC TRE shareholders thereon and reclassify the related dividend payable to withholding tax payable upon the declaration of such dividends. The requirement to withhold tax does not apply to the Company's shareholders appearing as individuals in its share register.

(a) One-off cash housing subsidies

Certain staff quarters, prior to 1998, were sold to certain of the Group's employees at preferential prices, subject to a number of eligibility requirements. In 1998, the State Council issued a circular which stipulated that the sale of quarters to employees at preferential prices should be terminated. In 2000, the State Council issued a further circular stating that cash subsidies should be made to certain eligible employees following the withdrawal of the allocation of staff quarters. However, the specific timetable and procedures for the implementation of these policies were to be determined by individual provincial or municipal governments based on the particular situation of the provinces or municipality.

Based on the relevant detailed local government regulations promulgated, certain entities within the Group adopted cash housing subsidy plans. In accordance with these plans, for those eligible employees who had not been allocated with quarters or who had not

been allocated with quarters up to the prescribed standards before the discounted sales of quarters were terminated, the Group determined to pay them one-off cash housing subsidies based on their years of service, positions and other criteria. Based on the available information, the Group estimated the required provision for these cash housing subsidies amounted to RMB4,142 million, which was charged to the statement of income for the year ended 31 December 2000 (the year in which the State Council circular in respect of cash subsidies was issued).

In January 2009, through the absorption of China Netcom (Group) Company Limited ('CNC China') by CUCL and the absorption of China Network Communications Group Corporation ('Netcom Group') by Unicom Group, the rights and obligations formerly undertaken by CNC China and Netcom Group were taken over by CUCL and Unicom Group separately. As at 31 December 2020, the Group's unpaid one-off cash housing subsides amounted to approximately RMB2,496 million. If the actual payments required for these one-off housing subsidies differ from the amount provided, Unicom Group will bear any additional payments required. If the actual payments are lower than the amount provided, the difference will be paid to Unicom Group.

Subject to fulfilment of all service and performance conditions under the Restricted A-Share Incentive Scheme which include the achievement of certain revenue and profit targets of the A Share Company, the Participants' individual performance appraisal, etc. (collectively referred to as 'vesting conditions'), the restriction over the Restricted Shares will be removed after the expiry of the corresponding Lock-Up Period for each tranche and the Participants will be fully entitled to these incentive shares. If the vesting conditions are not fulfilled and hence the Restricted Shares cannot be unlocked, the A Share Company shall repurchase the Restricted Shares based on the respective subscription price from the Participants.

With the fulfilment of the vesting conditions, Restricted Shares of 303,314,400 under the first tranche were approved for unlocking by the Board of Directors of A Share Company.

45. MATERIAL RELATED PARTY TRANSACTIONS

Unicom Group is a state-owned enterprise directly controlled by the PRC government. The PRC government is the Company's ultimate controlling party. Neither Unicom Group nor the PRC government publishes financial statements available for public use.

The PRC government controls a significant portion of the productive assets and entities in the PRC. The Group provides telecommunications services as part of its retail transactions, thus, is likely to have extensive transactions with the employees of other state-controlled entities, including their key management personnel and their close family members. These transactions are carried out on commercial terms that are consistently applied to all customers.

Management considers certain state-owned enterprises have material transactions with the Group in its ordinary course of business, which include but not limited to 1) rendering and receiving telecommunications services, including interconnection revenue/charges; 2) sharing certain telecommunications network infrastructure; 3) purchasing of goods, including use of public utilities; and 4) placing of bank deposits and borrowing money. The Group's telecommunications network depends, in large part, on interconnection with the network and on transmission lines service provided by other domestic carriers. These transactions are mainly carried out on terms comparable to those conducted with third parties or standards promulgated by relevant government authorities and have been reflected in the financial statements. Amounts due from domestic carriers are all derived from contracts with customers.

Management believes that meaningful information relating to related party transactions has been disclosed below.
