Chairman's Statement

Dear shareholders,

I hereby present the annual report of the Group for the financial year ended 31 December 2016 for shareholders' review. On behalf of the Board and all employees of the Company, I would like to express my sincere gratitude to all shareholders for your care for and support for the Company.

PRODUCT MARKET REVIEWS

Primary Aluminum Market

In 2016, the performance of primary aluminum price was significantly better than the market expectation. The international and domestic price of primary aluminum was heading upward against fluctuations.

In terms of the international market, benefiting from the improving macro risk appetite in the global market in 2016, the fundamentals of bulk commodities showed a favorable trend on the whole and prices of non-ferrous metals bounced back from the low at the beginning of the year. At the beginning of the year, the price of the three-month aluminum futures at LME sprung up to USD1,500 per tonne. Due to the preferential factors such as the rebound of macro environment and the slowing growth of the electrolytic aluminum supply in the global market, the price continually went upwards and surmounted USD1,600 per tonne in March. In June, the stronger expectation for interest rate rise by the US Federal Reserve and the EU Referendum in the UK added new uncertainties to the macro risks of the market and brought along the corresponding decrease and flagging fluctuations in the aluminum price. In the fourth quarter of 2016， as driven by the postponement of the interest rate rise resolution by the US Federal Reserve, the relentless surge of international crude oil price and the tight supply of spot aluminum in China, a large amount of capital flew into the market and the international aluminum price peaked in November at USD1,794.5 per tonne. Afterwards, the market was running stable gradually and the aluminum price smoothed down from its peak for the year due to profit taking. In 2016, the respective average prices of spot aluminum and three-month aluminum futures at LME amounted to USD1,604 per tonne and USD1,605 per tonne, representing a decrease of 3.5% and 4.6% from 2015, respectively. The decrease was narrowed down significantly.

40 ALUMINUM CORPORATION OF CHINA LIMITED

Chairman's Statement (Continued)

In terms of the domestic market, as affected by the traditional off season, holidays and festivals and other factors, the domestic price of aluminum futures showed a sluggish trend and fluctuated slightly on the whole at the beginning of the year; while during the same period, thanks to the flexible production implemented in succession by the domestic electrolytic aluminum enterprises at the end of 2015, the domestic price for spot aluminum stayed firm, which gave support to the price of the aluminum futures to some extent. After the Spring Festival, the domestic price of the aluminum futures rebounded rapidly upon a slight decrease, which was in striking contrast with the price plunge after the Spring Festival in the past years. Under the sustainable balance between supply and demand, the domestic price of the aluminum futures continued to rise and constantly broke the record. In April, the price of the three-month aluminum futures at SHFE quickly reached the peak in the first half of the year at RMB13,075 per tonne against the breakthrough price of RMB11,000 per tonne in March. Afterwards, the domestic aluminum price began to fall and fluctuated at low levels. In the second half of September, following the implementation of the Provisions on the Administration of the Running of Transport Vehicles with Out-of-gauge Freight on the Road (《超限運輸車輛行駛公路管理規定》) lately promulgated by China, the significant increase in the truck transport cost of electrolytic aluminum and the nearly full capacity of rail transport resulted in reduction of aluminum ingots inventory and increasingly tight supply of spot aluminum ingots. Consequently, the aluminum price surged vigorously. In the wake of the influx of a large amount of capital in the futures market, the price of the three-month aluminum futures at SHFE approached RMB15,000 per tonne, being the highest in the past two years, and it did not fall until the profit takings at the end of the year. In 2016, the respective average prices of spot aluminum and three-month aluminum futures at SHFE amounted to RMB12,261 per tonne and RMB12,101 per tonne, representing a decrease of 0.1% and 1.6% from 2015, respectively.

According to the statistics, the global output and consumption of primary aluminum for 2016 were approximately 58.87 million tonnes and approximately 59.60 million tonnes, respectively, representing a year-on-year increase of 2.9% and 3.0%, respectively. The domestic output and consumption of primary aluminum were approximately 32.50 million tonnes and approximately 32.70 million tonnes, respectively, representing a year-on-year increase of 4.8% and 6.7% respectively. As of the end of December 2016, the capacity utilization rate of primary aluminum in the world (inclusive of the PRC) was 79.81%, while that of the PRC was approximately 75.23%.

2016 ANNUAL REPORT 41

Chairman's Statement (Continued)

Alumina Market

In 2016, owning to the upsurge of the primary aluminum price and the increase in resumed production, the alumina price hiked up relentlessly.

In terms of the international market, as driven by the significant improvement of the demand and supply in the global aluminum market, especially the substantial reduction of the electrolytic aluminum production volume and the rising cost of raw materials in China, the domestic and international prices of the electrolytic aluminum began to recover steadily from the lows in recent years. Under such effect, the global alumina prices also began to bounce back and manifested an overall vigorously rising tendency for the year. In 2016, the lowest alumina price in the overseas market was USD197 per tonne at the beginning of the year, and the highest was the USD350.5 per tonne at the end of the year, representing an increase of 77.9% for the year. The annual average alumina price was USD254 per tonne, representing a decrease of 15.8% from 2015.

In terms of the domestic market, on account of the implementation of production reduction by domestic alumina enterprises and a favorable relationship of supply and demand, the alumina price bottomed out at the beginning of the year and began to accelerate its pace after the Spring Festival. After approaching the highest for the first half of the year at RMB1,998 per tonne in May, the price declined as affected by the resumed production of alumina. Nevertheless, as demands for alumina increased owing to the strong recovery momentum of production capacity of electrolytic aluminum plants, together with new transportation policies, rising costs, accidental events and other factors, the alumina price spiked since August 2016 and remained high till the end of the year. In 2016, the lowest alumina price in the domestic market was RMB1,525 per tonne at the beginning of the year, and the highest was the RMB3,080 per tonne at the end of the year, representing an increase of 101.97% for the year. The annual average alumina price was RMB2,070 per tonne, representing a decrease of 11.7% from 2015.

According to the statistics, the respective global output and consumption of alumina for 2016 was approximately 121.22 million tonnes and approximately 122.20 million tonnes, representing a year-on-year increase of 0.3% and 3.7%, respectively. The respective domestic output and consumption of alumina were approximately 60.16 million tonnes and approximately 64.40 million tonnes, representing a year-on-year increase of 2.6% and 4.2%, respectively. As of the end of December 2016, the alumina capacity utilization rate of alumina enterprises in the world (inclusive of the PRC) was approximately 81.26%, while that of the PRC was approximately 81.19%.

To the shareholders of Aluminum Corporation of China Limited(Established in the People's Republic of China with limited liability)

OPINION

We have audited the consolidated financial statements of Aluminum Corporation of China Limited (the "Company") and its subsidiaries (the "Group") set out on pages 142 to 332, which comprise the consolidated statement of financial position as at 31 December 2016, and 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.

BASIS FOR OPINION

We conducted our audit in accordance with International Standards on Auditing ("ISAs") issued by the International Auditing and Assurance Standards Board ("IAASB"). 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 Code of Ethics for Professional Accountants (the "Code") issued by the Hong Kong Institute of Certified Public Accountants, 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.

Independent Auditor's Report (Continued)

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. For each matter below, our description of how our audit addressed the matter is provided in that context.

We have fulfilled the responsibilities described in the Auditor's responsibilities for the audit of the consolidated financial statements section of our report, including in relation to these matters. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement of the consolidated financial statements. The results of our audit procedures, including the procedures performed to address the matters below, provide the basis for our audit opinion on the accompanying consolidated financial statements.

Key audit matter	How our audit addressed the key audit matter
Recognition of deferred tax assets
As at 31 December 2016, the Group had recorded net deferred tax assets of RMB1,427 million in the financial statements resulting from temporary differences and tax losses carried forward. The Group recognizes these deferred tax assets to the extent that it is probable that future taxable profits will allow the deferred tax assets to be recovered. The probability of recovery is impacted by uncertainties regarding the likely timing and level of future taxable profits together with tax planning strategies and the expiration dates of the losses. Due to the inherent uncertainty involved in determining the recoverability of the deferred tax assets, this is an area of focus for our audit. The Group's accounting policies and estimations on deferred tax assets are disclosed in notes 2.25 and 3, and details of deferred tax assets are disclosed in note 11 to the financial statements.	Our audit procedures included, amongst others, evaluating the assumptions and methodologies used by the Group in estimating future taxable profits. We evaluated management's assumptions in determining the future available taxable profits, specifically the future price of aluminum, and compared this with published forecasts issued by external industry analysts. We involved our tax specialists to assist us in evaluating the technical merits from a tax perspective of management's analysis. We tested the design and operation of internal control over the recognition process of deferred tax. We also focused on the adequacy of the disclosures included in note 11 to the financial statements regarding deferred tax assets.

KEY AUDIT MATTERS (Continued)

Key audit matter	How our audit addressed the key audit matter
Impairment of property, plant and equipment
The Group's property, plant and equipment ("PPE") amounting to RMB90,526 million as at 31 December 2016, comprised the largest portion of assets representing 47.63% of the Group's total assets and 85.64% of the long-lived assets. Management assessed impairment indicators for these items of PPE. For those with Impairment Indicators identified, management performed impairment testing by determining the recoverable amounts of the cash generating units ("CGUs") that the PPE belong to. The estimation of the recoverable amounts involved estimation of the discounted future cash flows which required significant judgement and estimation, specifically the future price of aluminum, production costs, operating expenses, discount rate and etc. Due to the inherent uncertainty involved in forecasting and discounting the future cash flows, which is the basis of the recoverable amounts, this is one of the key judgemental areas that our audit was focused on. The Group's accounting policies and estimations of impairment of property, plant and equipment are disclosed in notes 2.12 and 3, and details of the Group's impairment tests of property, plant and equipment are disclosed in note 6 to the financial statements.	Our audit procedures included, amongst others, an evaluation of the Group's assumptions used by management in determining the recoverable amounts for impairment testing purposes. We evaluated management's assumptions in determining the recoverable amounts of the CGUs that the PPE belong to, specifically the future price of aluminum by considering the forecast aluminum price and market trend as provided by external industry analysts. We also evaluated and challenged other key assumptions such as production volume, production costs and operating expenses by comparing the key assumptions to historical data, existing supporting documentation, evidence obtained subsequent to year-end, and industry forecasts. We involved our internal valuation specialists to assist us in evaluating the methodology and discount rate used in the calculation of value in use. In addition, we tested the design and operation of internal controls in place over the asset impairment testing. We also assessed the adequacy of the Group's disclosures included in note 6 to the financial statements regarding the key assumptions on impairment assessment.

KEY AUDIT MATTERS (Continued)

Key audit matter	How our audit addressed the key audit matter
Impairment of goodwill
The Group had goodwill amounting to RMB2,347 million as at 31 December 2016. Management performs goodwill impairment testing annually or more frequently if events or changes of circumstances indicate a potential impairment. The impairment testing was performed by comparing the recoverable amount of the CGU that goodwill is allocated to and the carrying value of goodwill. The determination of the recoverable amount involves estimation of the CGU's discounted future cash flows which requires significant judgement and estimation, specifically the future price of aluminum, production costs, operating expenses, discount rate, growth rate and etc. The annual impairment test is significant to our audit because the assessment process is complex and requires significant judgement. The Group's accounting policies and estimation of goodwill impairment are disclosed in notes 2.12 and 3, and details the Group's goodwill are disclosed in note 5 to the financial statements.	Our audit procedures included, amongst others, an evaluation of the Group's key assumptions adopted by management in determining the recoverable amount for goodwill impairment purposes. We evaluated management's assumptions of the CGU, including the future price of aluminum and the growth rate by considering the forecast aluminum price and market trend as provided by external industry analysts. We also evaluated and challenged other key assumptions, such as production volume, production costs, operating expenses, discount rate and etc. We involved our internal valuation specialists to assist us in evaluating the technique and discount rate used in the calculation of value in use. In addition, we tested the design and operation of internal controls in place over the goodwill impairment testing. We also assessed the adequacy of the Group's disclosures included in note 5 to the financial statements regarding the key assumptions of impairment assessment.

OTHER INFORMATION INCLUDED IN THE ANNUAL REPORT

The directors of the Company are responsible for the other information. The other information comprises 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.

RESPONSIBILITIES OF THE DIRECTORS FOR THE CONSOLIDATED FINANCIAL STATEMENTS

The directors of the Company 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 the disclosure requirements of 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 of the Company 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 of the Company either intend to liquidate the Group or to cease operations or have no realistic alternative but to do so.

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

2016 ANNUAL REPORT 139

Independent Auditor's Report (Continued)

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. Our report is made solely to you, as a body, 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 ISAs 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 ISAs, 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.

140 ALUMINUM CORPORATION OF CHINA LIMITED

Independent Auditor's Report (Continued)

AUDITOR'S RESPONSIBILITIES FOR THE AUDIT OF THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

• 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 to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with 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 Bennett S.H. Wai.

2.	BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES
	The principal accounting policies applied in the preparation of these financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

2.1	Basis of preparation
	The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards ("IFRSs") issued by the International Accounting Standards Board (the "IASB") and the disclosure requirements of the Hong Kong Companies Ordinance. They have been prepared on a historical cost basis, except for available-for-sale financial investments and financial assets and liabilities at fair value through profit or loss which have been measured at fair value. Disposal groups held for sale are stated at the lower of their carrying amounts and fair values less costs to sell.
	These financial statements are presented in thousands of Chinese Renminbi ("RMB") unless otherwise stated.
	Going concern
	As at 31 December 2016, the Group's current liabilities exceeded its current assets by approximately RMB16,518 million (31 December 2015: RMB17,345 million (restated)). The directors of the Company have considered the Group's available sources of funds as follows:

• The Group's expected net cash inflows from operating activities in 2017;

• Unutilised banking facilities of approximately RMB72,255 million as at 31 December 2016, of which amounts totalling RMB67,510 million will be subject to renewal during the next 12 months. The directors of the Company are confident that these banking facilities could be renewed upon expiration based on the Group's past experience and good credit standing; and

• Other available sources of financing from banks and other financial institutions given the Group's credit history.

2. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.1	Basis of preparation (Continued)
	Going concern (Continued)
	The directors of the Company believe that the Group has adequate resources to continue operations for the foreseeable future of not less than 12 months from the approval date of these financial statements. The directors of the Company therefore are of the opinion that it is appropriate to adopt the going concern basis in preparing the consolidated financial statements.
	Consolidation
	The consolidated financial statements comprise the financial statements of the Company and all of its subsidiaries for the year ended 31 December 2016. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Group controls an investee if and only if the Group has:

•	Power over the investee (i.e, existing rights that give it the current ability to direct the relevant activities of the investee);
•	Exposure, or rights, to variable returns from its involvement with the investee; and
•	The ability to use its power over the investee to affect its returns.
Generally, there is a presumption that a majority of voting rights result in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:
•	The contractual arrangement with the other vote holders of the investee;
•	Rights arising from other contractual arrangements; and
•	The Group's voting rights and potential voting rights.

2. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.1	Basis of preparation (Continued)
	Consolidation (Continued)
	The Group reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the statement of comprehensive income from the date the Group gains control until the date the Group ceases to control the subsidiary.
	Profit or loss and each component of other comprehensive income ("OCI") are attributed to the equity holders of the parent of the Group and to the non-controlling interests, even if this results in the non-controlling interests having a deficit balance. When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with the Group's accounting policies. All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation.
	A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction. If the Group loses control over a subsidiary, it:

• Derecognises the assets (including goodwill) and liabilities of the subsidiary;

• Derecognises the carrying amount of any non-controlling interests;

• Derecognises the cumulative translation differences recorded in equity;

• Recognises the fair value of the consideration received;

• Recognises the fair value of any investment retained;

• Recognises any surplus or deficit in profit or loss; and

• Reclassifies the parent's share of components previously recognised in OCI to profit or loss or retained earnings, as appropriate, as would be required if the Group had directly disposed of the related assets or liabilities.

2. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.1	Basis of preparation (Continued)
	Consolidation (Continued)

(a)	Merger accounting for business combinations under common control
	The consolidated financial statements incorporate the financial statements of the combining entities or businesses in business combination under common control as if they had been combined from the date when the combining entities or businesses first came under the control of the controlling party.
	The net assets of the combining entities or businesses are combined using the existing book values from the controlling parties' perspective. No amount is recognised in consideration for goodwill or excess of the acquirers' interest in the net fair value of the acquiree's identifiable assets, liabilities and contingent liabilities over cost at the time of the common control combination, to the extent of the continuation of the controlling party's interest.
	The consolidated statement of comprehensive income includes the results of each of the combining entities or businesses from the earliest date presented or since the date when the combining entities or businesses first came under common control, where this is a shorter period, regardless of the date of the common control combination.
	The comparative financial data have been restated to reflect the business combinations under common control occurred during this year as disclosed in note 38.
	Transaction costs, including professional fees, registration fees, costs of furnishing information to shareholders, costs or losses incurred in combining operations of the previously separate businesses and etc., incurred in relation to the common control combination that is to be accounted for by using the merger accounting method are recognised as expenses in the period in which they are incurred.

(b)

Acquisition method of accounting for other business combinations

The acquisition method of accounting is used to account for the acquisition of subsidiaries by the Group, other than common control combinations. The considerations transferred for the acquisition of a subsidiary are the fair values of the assets transferred, the liabilities incurred to the former owners of the acquiree and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the Group recognises any non-controlling interest in the acquiree either at fair value or at the non-controlling interest's proportionate share of the recognised amounts of the acquiree's identifiable net assets. The excess of the consideration transferred, the amount recognised for non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognised directly in profit or loss.

(c)	Subsidiaries
	A subsidiary is an entity, directly or indirectly, controlled by the Company. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee (i.e., existing rights that give the Group the current ability to direct the relevant activities of the investee).
	When the Company has, directly or indirectly, less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

(a)	the contractual arrangement with the other vote holders of the investee;
(b)	rights arising from other contractual arrangements; and
(c)	the Group's voting rights and potential voting rights.
Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are de-consolidated from the date that control ceases.
Inter-company transactions, balances, income and expenses on transactions between group companies are eliminated. Profits and losses resulting from inter-company transactions that are recognised in assets are also eliminated. Amounts reported by subsidiaries have been adjusted where necessary in the consolidated financial statements to conform with the policies adopted by the Group.

Subsidiaries (Continued)

In the Company's statement of financial position, as permitted under IFRS 1, the investments in subsidiaries acquired prior to 1 January 2008, being the date of transition to IFRS, are stated at deemed cost as required under the previously adopted accounting standards. Subsidiaries acquired after that date that are not classified as held for sale in accordance with IFRS 5 Non-current Assets Held for Sale and Discontinued Operations are stated at cost less provision for impairment losses. The results of subsidiaries are accounted for by the Company on the basis of dividends received and receivable.

2.2	Changes in accounting policies and disclosures
	The Group has adopted the following new and revised IFRSs (which include International Financial Reporting Standards, International Accounting Standards, and Interpretations and amendments) for the first time for the current year's financial statements.

	Except for the amendments to IFRS 10, IFRS 12 and IAS 28 (2011), and certain amendments included in the Annual Improvements 2012–2014 Cycle, which are not relevant to the preparation of the Group's financial statements, the principal effects of adopting these new and revised IFRSs are as follows:
	Amendments to IFRS 11 Accounting for Acquisitions of Interests in Joint Operations
	Amendments to IFRS 11 require that an acquirer of an interest in a joint operation in which the activity of the joint operation constitutes a business must apply the relevant principles for business combinations in IFRS 3.
	The amendments also clarify that a previously held interest in a joint operation is not remeasured on the acquisition of an additional interest in the same joint operation while joint control is retained. In addition, a scope exclusion has been added to IFRS 11 to specify that the amendments do not apply when the parties sharing joint control, including the reporting entity, are under common control of the same ultimate controlling party. The amendments apply to both the acquisition of the initial interest in a joint operation and the acquisition of any additional interests in the same joint operation. The amendments have had no impact on the Group as there has been no interest acquired in a joint operation during the year.
	Amendments to IAS 1 Disclosure Initiative
	Amendments to IAS 1 include narrow-focus improvements in respect of the presentation and disclosure in financial statements. The amendments clarify:

(i)	the materiality requirements in IAS 1;
(ii)	that specific line items in the statement of comprehensive income and the statement of financial position may be disaggregated;
(iii)	that entities have flexibility as to the order in which they present the notes to financial statements; and
(iv)	that the share of other comprehensive income of associates and joint ventures accounted for using the equity method must be presented in aggregate as a single line item, and classified between those items that will or will not be subsequently reclassified to profit or loss.

	Amendments to IAS 1 Disclosure Initiative (Continued)
	Furthermore, the amendments clarify the requirements that apply when additional subtotals are presented in the statement of financial position and the statement of comprehensive income. The amendments have had no significant impact on the Group's financial statements.
	Amendments to IAS 16 and IAS 38 Clarification of Acceptable Methods of Depreciation and Amortisation
	Amendments to IAS 16 and IAS 38 clarify the principle in IAS 16 and IAS 38 that revenue reflects a pattern of economic benefits that are generated from operating a business (of which the asset is part) rather than the economic benefits that are consumed through the use of the asset. As a result, a revenue-based method cannot be used to depreciate property, plant and equipment and may only be used in very limited circumstances to amortise intangible assets. The amendments are applied prospectively. The amendments have had no impact on the financial position or performance of the Group as the Group has not used a revenue-based method for the calculation of depreciation of its non-current assets.
	Amendments to IAS 27 (2011) Equity Method in Separate Financial Statements
	The IAS 27 (2011) Amendments allow entities to use the equity method to account for investments in subsidiaries, joint ventures and associates in their separate financial statements. Entities already applying IFRSs and electing to change to the equity method to account for investments in subsidiaries, joint ventures and associates in their separate financial statements are required to apply the change retrospectively. The amendments have had no significant impact on the Group, and the Company has not elected to change to equity method in its separate financial statement.

	Annual Improvements to IFRSs 2012–2014 Cycle
	Annual Improvements to IFRSs 2012–2014 Cycle issued in September 2014 sets out amendments to a number of IFRSs. Details of the amendments are as follows:
	IFRS 5 Non-current Assets Held for Sale and Discontinued Operations: Clarifies that changes to a plan of sale or a plan of distribution to owners should not be considered to be a new plan of disposal, rather it is a continuation of the original plan. Accordingly, there is no change in the application of the requirements in IFRS 5. The amendments also clarify that changing the disposal method does not change the date of classification of the non-current assets or disposal group held for sale.
	The amendments are applied prospectively. The amendments have had no impact on the Group as the Group did not have any disposal group held for sale at the end of the year.

2.3	Issued but not yet effective International Financial Reporting Standards (Continued)
	Further information about those IFRSs that are expected to be applicable to the Group is as follows:
	Amendments to IFRS 2 Classification and Measurement of Share-based Payment Transactions
	The IASB issued amendments to IFRS 2 in June 2016 that address three main areas: the effects of vesting conditions on the measurement of a cash-settled share-based payment transaction; the classification of a share-based payment transaction with net settlement features for withholding a certain amount in order to meet the employee's tax obligation associated with the share-based payment; and accounting where a modification to the terms and conditions of a share-based payment transaction changes its classification from cash-settled to equity-settled. The amendments clarify that the approach used to account for vesting conditions when measuring equity-settled share-based payments also applies to cash-settled share-based payments. The amendments introduce an exception so that a share-based payment transaction with net share settlement features for withholding a certain amount in order to meet the employee's tax obligation is classified in its entirety as an equity-settled share-based payment transaction when certain conditions are met. Furthermore, the amendments clarify that if the terms and conditions of a cash-settled share-based payment transaction are modified, with the result that it becomes an equity-settled share-based payment transaction, the transaction is accounted for as an equity-settled transaction from the date of the modification. The Group expects to adopt the amendments from 1 January 2018. The amendments are not expected to have any significant impact on the Group's financial statements.
	IFRS 9 Financial Instruments
	In July 2014, the IASB issued the final version of IFRS 9, bringing together all phases of the financial instruments project to replace IAS 39 and all previous versions of IFRS 9. The standard introduces new requirements for classification and measurement, impairment and hedge accounting. The Group expects to adopt IFRS 9 from 1 January 2018. The Group is currently assessing the impact of the standard.

2.3	Issued but not yet effective International Financial Reporting Standards (Continued)
	Amendments to IFRS 10 and IAS 28(2011) Sale or Contribution of Assets between an Investor and its Associate or Joint Venture
	Amendments to IFRS 10 and IAS 28 (2011) address an inconsistency between the requirements in IFRS 10 and in IAS 28 (2011) in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The amendments require a full recognition of a gain or loss when the sale or contribution of assets between an investor and its associate or joint venture constitutes a business. For a transaction involving assets that do not constitute a business, a gain or loss resulting from the transaction is recognised in the investor's profit or loss only to the extent of the unrelated investor's interest in that associate or joint venture. The amendments are to be applied prospectively. The previous mandatory effective date of amendments to IFRS 10 and IAS 28 (2011) was removed by the IASB in January 2016 and a new mandatory effective date will be determined after the completion of a broader review of accounting for associates and joint ventures. However, the amendments are available for adoption now.
	Amendments to IFRS 15 Clarifications to IFRS 15 Revenue from Contracts with Customers
	IFRS 15 establishes a new five-step model to account for revenue arising from contracts with customers. Under IFRS 15, revenue is recognised at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. The principles in IFRS 15 provide a more structured approach for measuring and recognising revenue. The standard also introduces extensive qualitative and quantitative disclosure requirements, including disaggregation of total revenue, information about performance obligations, changes in contract asset and liability account balances between periods and key judgements and estimates. The standard will supersede all current revenue recognition requirements under IFRSs. In June 2016, the IASB issued amendments to IFRS 15 to address the implementation issues on identifying performance obligations, application guidance on principal versus agent and licences of intellectual property, and transition. The amendments are also intended to help ensure a more consistent application when entities adopt IFRS 15 and decrease the cost and complexity of applying the standard. Either a full retrospective application or a modified retrospective application is required for annual periods beginning on or after 1 January 2018. Early adoption is permitted. During the year ended 31 December 2016, the Group performed a preliminary assessment on the impact of the adoption of IFRS 15, which is subject to changes arising from a more detailed ongoing analysis. Furthermore, the Group is considering the clarifications issued by the IASB in 2016 and will monitor any further developments.

	Amendments to IFRS 15 Clarifications to IFRS 15 Revenue from Contracts with Customers (Continued)
	The Group's principal activities consist of the manufacture and sale of alumina, the manufacture and sale of primary aluminium and aluminum alloy products, trading and logistics of non-ferrous metal products, coal, electric power and other energy businesses. Upon initial evaluation, the Group expects to adopt IFRS 15 on 1 January 2018 using the modified retrospective method and the effect of adoption on the Group's financial statements is not expected to be material.
	IFRS 16 Leases
	IFRS 16 replaces IAS 17 Leases, IFRIC-4 Determining whether an Arrangement contains a Lease, SIC-15 Operating Leases – Incentives and SIC-27 Evaluating the Substance of Transactions Involving the Legal Form of a Lease. The standard sets out the principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to recognise assets and liabilities for most leases. The standard includes two recognition exemptions for lessees – leases of low-value assets and short-term leases. At the commencement date of a lease, a lessee will recognise a liability to make lease payments and an asset representing the right to use the underlying asset during the lease term. The right-of-use asset is subsequently measured at cost less accumulated depreciation and any impairment losses unless the right-of-use asset meets the definition of investment property in IAS 40. The lease liability is subsequently increased to reflect the interest on the lease liability and reduced for the lease payments. Lessees will be required to separately recognise the interest expense on the lease liability and the depreciation expense on the right-of-use asset. Lessees will also be required to remeasure the lease liability upon the occurrence of certain events, such as change in the lease term and change in future lease payments resulting from a change in an index or rate used to determine those payments. Lessees will generally recognise the amount of the remeasurement of the lease liability as an adjustment to the right-of-use asset. Lessor accounting under IFRS 16 is substantially unchanged from the accounting under IAS 17. Lessors will continue to classify all leases using the same classification principle as in IAS 17 and distinguish between operating leases and finance leases. The Group expects to adopt IFRS 16 on 1 January 2019 and is currently assessing the impact of IFRS 16 upon adoption.

	Amendments to IAS 7 Disclosure Initiative
	Amendments to IAS 7 require an entity to provide disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes. The amendments will result in additional disclosure to be provided in the financial statements. The Group expects to adopt the amendments from 1 January 2017.
	Amendments to IAS 12 Recognition of Deferred Tax Assets for Unrealised Losses
	Amendments to IAS 12 were issued with the purpose of addressing the recognition of deferred tax assets for unrealised losses related to debt instruments measured at fair value, although they also have a broader application for other situations. The amendments clarify that an entity, when assessing whether taxable profits will be available against which it can utilise a deductible temporary difference, needs to consider whether tax law restricts the sources of taxable profits against which it may make deductions on the reversal of that deductible temporary difference. Furthermore, the amendments provide guidance on how an entity should determine future taxable profits and explain the circumstances in which taxable profit may include the recovery of some assets for more than their carrying amount. The Group expects to adopt the amendments from 1 January 2017.
	Amendments to IAS 40 Transfers of Investment Property
	The amendments clarify when an entity should transfer property, including property under construction or development into, or out of investment property. The amendments state that a change in use occurs when the property meets, or ceases to meet, the definition of investment property and there is evidence of the change in use. A mere change in management's intentions for the use of a property does not provide evidence of a change in use. The amendments are effective for annual periods beginning on or after 1 January 2018. Early application of the amendments is permitted and must be disclosed. The Group expects to adopt the amendments from 1 January 2018.

	IAS 28 Investments in Associates and Joint Ventures
	The amendments clarifies that:

• An entity that is a venture capital organisation, or other qualifying entity, may elect, at initial recognition on an investment-by-investment basis, to measure its investments in associates and joint ventures at fair value through profit or loss.

• If an entity that is not itself an investment entity has an interest in an associate or joint venture that is an investment entity, the entity may, when applying the equity method, elect to retain the fair value measurement applied by that investment entity associate or joint venture to the investment entity associate's or joint venture's interests in subsidiaries. This election is made separately for each investment entity associate or joint venture, at the later of the date on which (a) the investment entity associate or joint venture is initially recognised; (b) the associate or joint venture becomes an investment entity; and (c) the investment entity associate or joint venture first becomes a parent.

The amendments should be applied retrospectively and are effective from 1 January 2018, with earlier application permitted. If an entity applies those amendments for an earlier period, it must disclose that fact. The Group expects to adopt the amendments from 1 January 2018.

	IFRS 12 Disclosure of Interests in Other Entities
	The amendments clarify that the disclosure requirements in IFRS 12, other than those in paragraphs B10–B16, apply to an entity's interest in a subsidiary, a joint venture or an associate (or a portion of its interest in a joint venture or an associate) that is classified (or included in a disposal group that is classified) as held for sale. The amendments are effective from 1 January 2017 and must be applied retrospectively. The Group expects to adopt the amendments from 1 January 2017.
2.4	Investments in joint ventures and associates
	A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.
	An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but is not control or joint control over those policies.
	The Group's investments in associates and joint ventures are accounted for using the equity method.
	Under the equity method, the investment in an associate or a joint venture is initially recognised at cost. The carrying amount of the investment is adjusted to recognise changes in the Group's share of net assets of the associate or joint venture since the acquisition date. Goodwill relating to the associate or joint venture is included in the carrying amount of the investment, and tested for impairment each year end.

2.4	Investments in joint ventures and associates (Continued)
	The consolidated statement of comprehensive income reflects the Group's share of the results of operations of the associate or joint venture. Any change in OCI of those investees is presented as part of the Group's OCI. In addition, when there has been a change recognised directly in the equity of the associate or joint venture, the Group recognises its share of any changes, when applicable, in the consolidated statement of changes in equity. Unrealised gains and losses resulting from transactions between the Group and the associate or joint venture are eliminated to the extent of the interest in the associate or joint venture.
	The aggregate of the Group's share of profit or loss of an associate and a joint venture is shown on the face of the consolidated statement of comprehensive income outside operating profit and represents profit or loss after tax and non-controlling interests in the subsidiaries of the associate or joint venture.
	The financial statements of the associate or joint venture are prepared for the same reporting period as the Group. When necessary, adjustments are made to bring the accounting policies in line with those of the Group.
	After application of the equity method, the Group determines whether it is necessary to recognise an impairment loss on its investment in its associate or joint venture. At each reporting date, the Group determines whether there is objective evidence that the investment in the associate or joint venture is impaired. If there is such evidence, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate or joint venture and its carrying value, then recognises the loss in profit or loss.

2.4	Investments in joint ventures and associates (Continued)
	If an investment in an associate becomes an investment in a joint venture or vice versa, the retained interest is not remeasured. Instead, the investment continues to be accounted for under the equity method. In all other cases, upon loss of significant influence over the associate or joint control over the joint venture, the Group measures and recognises any retained investment at its fair value. Any difference between the carrying amount of the associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and the proceeds from disposal is recognised in profit or loss.
	The Group's investments in associates and joint ventures are classified as non-current assets and are stated at cost less any impairment losses. The results of associates and joint ventures are included in the Group's profit or loss to the extent of dividends received and receivable.
	When an investment in an associate or a joint venture is classified as held for sale, it is accounted for in accordance with IFRS 5 Non-current Assets Held for Sale and Discontinued Operations.
2.5	Segment reporting
	Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-makers, who are responsible for allocating resources and assessing the performance of the operating segments, have been identified as the presidents of the Company that make strategic decisions.

2.7	Fair value measurement
	The Group measures its derivative financial instruments and available-for-sale financial investments at fair value at the end of each reporting period. Also, the fair values of financial instruments measured at amortised cost are disclosed in note 36.
	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

• In the principal market for the asset or liability; or

• In the absence of a principal market, in the most advantageous market for the asset or liability.

The principal or the most advantageous market must be accessible by the Group. The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest.

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

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

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

Level 1	–	Based on quoted (unadjusted) market prices in active markets for identical assets or liabilities
Level 2	–	Based on valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable
Level 3	–	Based on valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

	For assets and liabilities that are recognised in the financial statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing categorisation (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.
2.8	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 entity operates (the "functional currency"). The consolidated financial statements are presented in RMB, which is the Company's functional currency and the Group's presentation currency.

2.8 Foreign currency translation (Continued)

(b)	Transactions and balances
	Foreign currency transactions recorded by the entities in the Group are initially recorded using their respective functional currency rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency rates of exchange ruling at the end of the reporting period. Differences arising on settlement or translation of monetary items are recognised in profit or loss.
	Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was measured. The gain or loss arising on translation of a non-monetary item measured at fair value is treated in line with the recognition of the gain or loss on change in fair value of the item.
(c)	Group companies
	The results and financial positions of all the group entities (none of which has the currency of a hyper-inflationary economy) that has a functional currency different from the presentation currency are translated into the presentation currency as follows:

(i)	assets and liabilities in each statement of financial position presented are translated at the closing rates at the end of the reporting period;
(ii)	income and expenses in each statement of comprehensive 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 rates at the dates of the transactions); and
(iii)	all resulting exchange differences are recognised in other comprehensive income. Upon disposal of a foreign operation, the other comprehensive income related to the foreign operation is reclassified to profit or loss.

	Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the closing rate. Exchange differences arising are recognised in other comprehensive income.

2.9	Property, plant and equipment
	Property, plant and equipment, other than construction in progress, are stated at cost less accumulated depreciation and any impairment losses. When an item of property, plant and equipment is classified as held for sale or when it is part of a disposal group classified as held for sale, it is not depreciated and is accounted for in accordance with IFRS 5. The cost of an item of property, plant and equipment comprises its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use.
	Expenditure incurred after items of property, plant and equipment have been put into operation, such as repairs and maintenance, is normally charged to profit or loss in the period in which it is incurred. In situations where the recognition criteria are satisfied, the expenditure for a major inspection is capitalised in the carrying amount of the asset as a replacement. Where significant parts of property, plant and equipment are required to be replaced at intervals, the Group recognises such parts as individual assets with specific useful lives and depreciates them accordingly.

2.9	Property, plant and equipment (Continued)
	Depreciation is calculated on the straight-line basis to write off the cost of each item of property, plant and equipment to its residual value over its estimated useful life. The principal annual rates used for this purpose are as follows:

Buildings	8–45 years
Machinery	3–30 years
Transportation facilities	6–10 years
Office and other equipment	3–10 years

The assets' depreciation method, residual values and useful lives are reviewed and adjusted, if appropriate, at the end of each reporting period. An item of property, plant and equipment including any significant part initially recognised is derecognised upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss on disposal or retirement recognised in profit or loss in the year the asset is derecognised is the difference between the net sales proceeds and the carrying amount of the relevant asset.

Construction in progress ("CIP") represents buildings under construction, and plant and equipment pending for installation, and is stated at cost less any impairment losses. Cost comprises construction expenditures, other expenditures necessary for the purpose of preparing the CIP for its intended use and those borrowing costs incurred before the asset is ready for its intended use that is eligible for capitalisation. CIP is transferred to property, plant and equipment when the CIP is ready for its intended use.

2.10 Intangible assets

(a)	Goodwill
	Goodwill arises on the acquisition of subsidiaries, associates and joint ventures and represents the excess of the consideration transferred over the fair value of the Group's share of the net identifiable assets of the acquiree at the date of acquisition.
	For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the cash-generating units, or groups of cash-generating units, that is expected to benefit from the synergies of the combination. Each unit or group of units to which the goodwill is allocated represents the lowest level within the entity at which the goodwill is monitored for internal management purposes. Goodwill is monitored at the operating segment level.
	Goodwill impairment reviews are undertaken annually or more frequently if events or changes in circumstances indicate a potential impairment. The carrying value of goodwill is compared to the recoverable amount, which is the higher of value in use and the fair value less costs of disposal. Any impairment is recognised immediately as an expense and is not subsequently reversed.
(b)	Mining rights and mineral exploration rights
	The Group's mineral exploration rights and mining rights relate to coal, bauxite and other mines.

(i)	Recognition
	Mineral exploration rights and mining rights are initially recorded at cost which includes the acquisition consideration, qualifying exploration and other direct costs. The mineral exploration rights are stated at cost less any impairment, and the mining rights are stated at cost less any amortisation and impairment.

(b) Mining rights and mineral exploration rights (Continued)

(ii)	Reclassification
	Mineral exploration rights are converted to mining rights when technical feasibility and commercial viability of extracting a mineral resource are demonstrable, and are subject to amortisation when commercial production has commenced.
	The Group assesses the stage of each mine under construction to determine when a mine moves into the production stage. The criteria used to assess the start date are determined based on the unique nature of each mine construction project. The Group considers various relevant criteria, such as completion of a reasonable period of testing of the mine and equipment, ability to produce in saleable form (within specifications) and ability to sustain ongoing production to assess when a mine is substantially complete and ready for its intended use.
(iii)	Amortisation
	Amortisation of bauxite and other mining rights (except for coal mining rights) is provided on a straight-line basis according to the shorter of the expiration date of the mining certificate and the mineable period of natural resources. Estimated mineable periods of the majority of the mining rights range from 3 to 30 years.
	Coal mining rights are amortised on a unit-of-production basis over the economically recoverable reserves evaluated based on the reserves estimated in accordance with the standards in the Solid Mineral Resource/Reserve Classification of the PRC (GB/T17766-1999) of the mine concerned.
(iv)	Impairment
	An impairment review is performed when there are indicators that the carrying amount of the mineral exploration rights and mining rights may exceed their recoverable amounts. To the extent that this occurs, the excess is fully provided as an impairment loss.

(c)	Computer software
	Acquired computer software licenses 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, which do not exceed 10 years. Costs associated with maintaining computer software programmes are recognised as an expense as incurred.
(d)	Other intangible assets
	Other intangible assets mainly include profit sharing right of Maochang mine, which are initially recorded at costs incurred to acquire the specific right. Amortisation is calculated on the straight-line basis over its estimated useful life. The estimated useful live of profit sharing right of Maochang mine is 22.5 years.
(e)	Periodic review of the useful lives and amortisation method
	For intangible assets with finite useful lives, the estimated useful lives and amortisation method are reviewed annually at the end of each reporting period and adjusted when necessary.

2.11	Research and development costs
	Research and development expenditures are classified as research expenditures and development expenditures according to the nature of the expenditures and whether there is significant uncertainty of development activities transforming to assets.
	Research expenditures are recognised in profit or loss for the current period. Development expenditures are recognised as assets when all of the following criteria are met:

(i) it is technically feasible to complete the asset so that it will be available for use or sale;

2. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.11 Research and development costs (Continued)

(ii)	management intends to complete the asset and intends and has the ability to use or sell it;
(iii)	it can be demonstrated that the asset will generate probable future economic benefits;
(iv)	there are adequate technical, financial and other resources to complete the development of the asset and management has the ability to use or sell the asset; and
(v)	the expenditure attributable to the asset during its development phase can be reliably measured.

	Development expenditures that do not meet the criteria above are recorded in profit or loss for the current period as incurred. Development expenditures that have been recorded in profit or loss in previous periods will be not recognized as assets in subsequent periods. Capitalized development expenditures are included in property, plant and equipment and intangible assets as appropriate according to their natures.
2.12	Impairment of non-financial assets
	Where an indication of impairment exists, or when annual impairment testing for an asset is required (for example goodwill or intangible assets with indefinite useful life), the asset's recoverable amount is estimated. An asset's recoverable amount is the higher of the asset's or cash-generating unit's value in use and its fair value less costs of disposal, and is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets, in which case the recoverable amount is determined for the cash-generating unit to which the asset belongs.
	An impairment loss is recognised only if the carrying amount of an asset exceeds its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. An impairment loss is charged to profit or loss in the period in which it arises in those expense categories consistent with the function of the impaired asset.

2.12	Impairment of non-financial assets (Continued)
	An assessment is made at the end of each reporting period as to whether there is an indication that previously recognised impairment losses may no longer exist or may have decreased. If such an indication exists, the recoverable amount is estimated. A previously recognised impairment loss of an asset other than goodwill is reversed only if there has been a change in the estimates used to determine the recoverable amount of that asset, but not to an amount higher than the carrying amount that would have been determined (net of any depreciation/amortisation) had no impairment loss been recognised for the asset in prior years. A reversal of such an impairment loss is credited to profit or loss in the period in which it arises.
2.13	Investment properties
	Investment properties are interests in land and buildings (including the leasehold interest under an operating lease for a property which would otherwise meet the definition of an investment property) held to earn rental income and/or for capital appreciation, rather than for use in the production or supply of goods or services or for administrative purposes; or for sale in the ordinary course of business. Such properties are measured initially at cost, including transaction costs. After initial recognition, the Group uses the cost model to measure all of its investment properties.
	Depreciation is calculated on the straight-line basis to write off the cost to investment property's residual value over its estimated useful life. The estimated useful lives are as follows:

Buildings	50 years
Land use right	40–70 years

The carrying amounts of investment properties measured using the cost method are reviewed for impairment when events or changes in circumstances indicate that the carrying amounts may not be recoverable.

Any gains or losses on the retirement or disposal of an investment property are recognised in profit or loss in the year of the retirement or disposal.

2.14	Non-current assets and disposal groups held for sale
	Non-current assets and disposal groups are classified as held for sale if their carrying amounts will be recovered principally through a sales transaction rather than through continuing use. For this to be the case, the asset or disposal group must be available for immediate sale in its present condition subject only to terms that are usual and customary for the sale of such assets or disposal groups and its sale must be highly probable. All assets and liabilities of a subsidiary classified as a disposal group are reclassified as held for sale regardless of whether the Group retains a non-controlling interest in its former subsidiary after the sale.
	Non-current assets and disposal groups (other than financial assets) classified as held for sale are measured at the lower of their carrying amounts and fair values less costs to sell. Property, plant and equipment and intangible assets classified as held for sale are not depreciated or amortised.
2.15	Financial assets

(a)	Classification
	The Group classifies its financial assets in the following categories: at fair value through profit or loss, loans and receivables and available-for-sale financial investments. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition.

(i)

Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss include financial assets held for trading and financial assets designated upon initial recognition as at fair value through profit or loss. Financial assets are classified as held for trading if they are acquired for the purpose of sale in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments as defined by IAS 39.

2.15 Financial assets (Continued)

(a) Classification (Continued)

(i)	Financial assets at fair value through profit or loss (Continued)
	Financial assets at fair value through profit or loss are carried in the consolidated statement of financial position at fair value with positive net changes in fair value presented as other income and gains and negative net changes in fair value presented as finance costs. These net fair value changes do not include any dividends or interest earned on these financial assets, which are recognised in accordance with the policies set out for "Revenue recognition" below.
	Financial assets designated upon initial recognition as at fair value through profit or loss are designated at the date of initial recognition and only if the criteria in IAS 39 are satisfied.
	Derivatives embedded in host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated as at fair value through profit or loss. These embedded derivatives are measured at fair value with changes in fair value recognised in profit or loss. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through profit or loss category.

(a) Classification (Continued)

(ii)	Loans and receivables
	Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. After initial measurement, such assets are subsequently measured at amortised cost using the effective interest rate method less any allowance for impairment. Amortised cost is calculated by taking into account any discount or premium on acquisition and includes fees or costs that are an integral part of the effective interest rate. The effective interest rate amortisation is included in other income and gains in profit or loss. The loss arising from impairment is recognised in profit or loss in finance costs for loans and in other expenses for receivables.
(iii)	Available-for-sale financial investments
	Available-for-sale financial investments are non-derivative financial assets in listed and unlisted equity investments and debt securities. Equity investments classified as available for sale are those which are neither classified as held for trading nor designated as at fair value through profit or loss. Debt securities in this category are those which are intended to be held for an indefinite period of time and which may be sold in response to needs for liquidity or in response to changes in market conditions.
	After initial recognition, available-for-sale financial investments are subsequently measured at fair value, with unrealised gains or losses recognised as other comprehensive income in the available-for-sale investment revaluation reserve until the investment is derecognised, at which time the cumulative gain or loss is recognised in profit or loss in other income, or until the investment is determined to be impaired, when the cumulative gain or loss is reclassified from the available-for-sale investment revaluation reserve to profit or loss in other gains or losses. Interest and dividends earned whilst holding the available-for-sale financial investments are reported as interest income and dividend income, respectively and are recognised in profit or loss as other income in accordance with the policies set out for "Interest income" and "Dividend income" below.

(a) Classification (Continued)

(iii)	Available-for-sale financial investments (Continued)
	When the fair value of unlisted equity investments cannot be reliably measured because (a) the variability in the range of reasonable fair value estimates is significant for that investment or (b) the probabilities of the various estimates within the range cannot be reasonably assessed and used in estimating fair value, such investments are stated at cost less any impairment losses.
	The Group evaluates whether the ability and intention to sell its available-for-sale financial assets in the near term are still appropriate. When, in rare circumstances, the Group is unable to trade these financial assets due to inactive markets, the Group may elect to reclassify these financial assets if management has the ability and intention to hold the assets for the foreseeable future or until maturity.
	For a financial asset reclassified from the available-for-sale category, the fair value carrying amount at the date of reclassification becomes its new amortised cost and any previous gain or loss on that asset that has been recognised in equity is amortised to profit or loss over the remaining life of the investment using the effective interest rate. Any difference between the new amortised cost and the maturity amount is also amortised over the remaining life of the asset using the effective interest rate. If the asset is subsequently determined to be impaired, then the amount recorded in equity is reclassified to profit or loss.

(b)	Recognition and measurement
	All regular purchases and sales of financial assets are recognised on the trade date, that is the date that the Group commits to purchase or sell the asset. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the period generally established by regulation or convention in the marketplace. Investments are initially recognised at fair value plus transaction costs, except in the case of financial assets recorded at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognised at fair value and transaction costs are expensed in profit or loss. Financial assets are derecognised when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale financial investments and financial assets at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are subsequently carried at amortised cost using the effective interest method.
(c)	Derecognition of financial assets
	A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognised (i.e. removed from the Group's consolidated statement of financial position) when:

• the rights to receive cash flows from the asset have expired; or

• the Group has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a "pass-through" arrangement; and either (a) the Group has transferred substantially all the risks and rewards of the asset, or (b) the Group has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

(c)	Derecognition of financial assets (Continued)
	When the Group has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent it has retained the risk and rewards of ownership of the asset. When it has neither transferred nor retained substantially all the risks and rewards of the asset nor transferred control of the asset, the Group continues to recognise the transferred asset to the extent of the Group's continuing involvement. In that case, the Group also recognises an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained.
	Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Group could be required to repay.
(d)	Impairment of financial assets
	The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired. An impairment exists if one or more events that occurred after the initial recognition of the asset have an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be reliably estimated. Evidence of impairment may include indications that a debtor or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganisation and observable data indicating that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults.

2.15 Financial assets (Continued)

(d)	Impairment of financial assets (Continued)
	Financial assets carried at amortised cost
	For financial assets carried at amortised cost, the Group first assesses whether impairment exists individually for financial assets that are individually significant, or collectively for financial assets that are not individually significant. If the Group determines that no objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, it includes the asset in a group of financial assets with similar credit risk characteristics and collectively assesses them for impairment. Assets that are individually assessed for impairment and for which an impairment loss is, or continues to be, recognised are not included in a collective assessment of impairment.
	The amount of any impairment loss identified is measured as the difference between the asset's carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not yet been incurred). The present value of the estimated future cash flows is discounted at the financial asset's original effective interest rate (i.e., the effective interest rate computed at initial recognition).
	The carrying amount of the asset is reduced through the use of an allowance account and the loss is recognised in profit or loss. Interest income continues to be accrued on the reduced carrying amount using the rate of interest used to discount the future cash flows for the purpose of measuring the impairment loss. Loans and receivables together with any associated allowance are written off when there is no realistic prospect of future recovery and all collateral has been realised or has been transferred to the Group.
	If, in a subsequent period, the amount of the estimated impairment loss increases or decreases because of an event occurring after the impairment was recognised, the previously recognised impairment loss is increased or reduced by adjusting the allowance account. If a write-off is later recovered, the recovery is credited to other expenses in profit or loss.

(d)	Impairment of financial assets (Continued)
	Available-for-sale financial investments
	For available-for-sale financial investments, the Group assesses at the end of each reporting period whether there is objective evidence that an investment or a group of investments is impaired.
	If an available-for-sale asset is impaired, an amount comprising the difference between its cost (net of any principal payment and amortisation) and its current fair value, less any impairment loss previously recognised in profit or loss, is removed from other comprehensive income and recognised in profit or loss.
	In the case of equity investments classified as available-for-sale financial investments, a significant or prolonged decline in the fair value of the security below its cost is considered as an indicator that the securities are impaired. If any such evidence exists for available-for-sale financial investments, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in the statement of comprehensive income – is removed from other comprehensive income and recognised in profit or loss. Impairment losses recognised in profit or loss on equity instruments are not reversed through profit or loss.
	The determination of what is "significant" or "prolonged" requires judgement. In making this judgement, the Group evaluates, among other factors, the duration or extent to which the fair value of an investment is less than its cost.

	��
	Available-for-sale financial investments (Continued)
	In the case of debt instruments classified as available for sale, impairment is assessed based on the same criteria as financial assets carried at amortised cost. However, the amount recorded for impairment is the cumulative loss measured as the difference between the amortised cost and the current fair value, less any impairment loss on that investment previously recognised in profit or loss. Future interest income continues to be accrued based on the reduced carrying amount of the asset and is accrued using the rate of interest used to discount the future cash flows for the purpose of measuring the impairment loss. The interest income is recorded as part of finance income. Impairment losses on debt instruments are reversed through profit or loss if the subsequent increase in fair value of the instruments can be objectively related to an event occurring after the impairment loss was recognised in profit or loss.

2.16 Financial liabilities

(a)	Initial recognition and measurement
	Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.
	All financial liabilities are recognised initially at fair value plus, in the case of loans and borrowings, directly attributable transaction costs.
	The Group's financial liabilities include financial liabilities at fair value through profit or loss and loans and borrowings.

2. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.16 Financial liabilities (Continued)

(b)	Subsequent measurement
	The subsequent measurement of financial liabilities depends on their classification as follows:
	Loans and borrowings
	After initial recognition, loans and borrowings are subsequently measured at amortised cost, using the effective interest rate method unless the effect of discounting would be immaterial, in which case they are stated at cost. Gains and losses are recognised in profit or loss when the liabilities are derecognised as well as through the effective interest rate amortisation process.
	Amortised cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the effective interest rate. The effective interest rate amortisation is included in finance costs in profit or loss.
	Financial liabilities at fair value through profit or loss
	Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss.
	Financial liabilities are classified as held for trading if they are acquired for the purpose of repurchasing in the near term. This category includes derivative financial instruments entered into by the Group that are not designated as hedging instruments in hedge relationships as defined by IAS 39. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments. Gains or losses on liabilities held for trading are recognised in profit or loss. The net fair value gain or loss recognised in profit or loss does not include any interest charged on these financial liabilities.
	Financial liabilities designated upon initial recognition at fair value through profit or loss are designated at the date of initial recognition and only if the criteria of IAS 39 are satisfied.

2.16 Financial liabilities (Continued)

(b)	Subsequent measurement (Continued)
	Financial guarantee contracts
	Financial guarantee contracts issued by the Group are those contracts that require a payment to be made to reimburse the holder for a loss it incurs because the specified debtor fails to make a payment when due in accordance with the terms of a debt instrument. A financial guarantee contract is recognised initially as a liability at its fair value, adjusted for transaction costs that are directly attributable to the issuance of the guarantee. Subsequent to initial recognition, the Group measures the financial guarantee contract at the higher of: (i) the amount of the best estimate of the expenditure required to settle the present obligation at the end of the reporting period; and (ii) the amount initially recognised less, when appropriate, cumulative amortisation.
(c)	Derecognition of financial liabilities
	A financial liability is derecognised when the obligation under the liability is discharged or cancelled, or expires.
	When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and a recognition of a new liability, and the difference between the respective carrying amounts is recognised in profit or loss.

2.17	Offsetting financial instruments
	Financial assets and liabilities are offset and the net amount reported in the consolidated statement of financial position when there is a legally enforceable right to offset the recognised amounts and there is an intention to settle on a net basis or realise the asset and settle the liability simultaneously.

2. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.18	Derivative financial instruments
	Initial recognition and subsequent measurement
	The Group uses derivative financial instruments, such as forward currency contracts and interest rate swaps, to hedge its foreign currency risk and interest rate risk, respectively. Such derivative financial instruments are initially recognised at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. Derivatives are carried as assets when the fair value is positive and as liabilities when the fair value is negative.
	Any gains or losses arising from changes in fair value of derivatives are taken directly to profit or loss, except for the effective portion of cash flow hedges, which is recognised in other comprehensive income and later reclassified to profit or loss when the hedged item affects profit or loss.
2.19	Inventories
	Inventories comprise raw materials, work-in-progress, finished goods, spare parts and packaging materials and others, and are stated at the lower of cost and net recoverable amount. Cost is determined using the weighted average method. Work-in-progress and finished goods comprise materials, direct labour and an appropriate proportion of all production overhead expenditure (based on the normal operating capacity). Borrowing costs are excluded.
	Provision for impairment of inventories is usually determined by the excess of cost over net recoverable amount and recorded in profit or loss. Net recoverable amounts are determined based on the estimated selling price less estimated conversion costs, selling expenses and related taxes in the ordinary course of business. Provision for or reversal of provision for impairment of inventories is recognised within "cost of sales" in profit or loss.

2.20	Trade and notes receivables and other receivables
	Trade and notes receivables and other receivables are amounts due from customers for merchandise sold or services performed in the ordinary course of business. If collection of these receivables is expected in one year or less (or in the normal operating cycle of the business if longer), they are classified as current assets.
	Trade and notes receivables and other receivables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method, less provision for impairment.
2.21	Cash and cash equivalents
	For the purpose of the consolidated statement of cash flows, cash and cash equivalents comprise cash on hand and demand deposits, and short term highly liquid investments that are readily convertible into known amounts of cash, are subject to an insignificant risk of changes in value, and have a short maturity of generally within three months when acquired, less bank overdrafts which are repayable on demand and form an integral part of the Group's cash management.
	For the purpose of the consolidated statement of financial position, cash and cash equivalents comprise cash on hand and at banks, including term deposits, and assets similar in nature to cash, which are not restricted as to use.
2.22	Other income
	Other income mainly includes government grants, which are recognised when the Group fulfils the conditions attached to them and there is reasonable assurance that the grant will be received. When the government grant is in the form of monetary assets, it is measured at the actual amount received. When the grant is provided based on a pre-determined rate, it is measured at the fair value of the amount receivable.
	Asset-related government grants are recognised when the government document designates that the government grants are used for constructing or forming long-term assets. If the government document is inexplicit, the Group should make a judgement based on the basic conditions to obtain the government grants, and recognises them as asset-related government grants if the conditions are to construct or to form long-term assets. Otherwise, the government grants should be income-related.

2. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

2.22	Other income (Continued)
	Asset-related government grants are recognised as deferred income and are amortised evenly in profit or loss over the useful lives of the related assets.
	Income-related government grants that are used to compensate subsequent related expenses or losses of the Group are recognised as deferred income and recorded in profit or loss when the related expenses or losses are incurred. When the grants are used to compensate expenses or losses that were already incurred, they are directly recognised in profit or loss for the current period.
2.23	Trade and notes payables and other payables
	Trade and notes payables and other payables are mainly obligations to pay for goods, equipment or services that have been acquired in the ordinary course of business from suppliers and service providers. These payables are classified as current liabilities if they are due within one year or less (or in the normal operating cycle of the business if longer).
2.24	Employee benefits
	Employee benefits mainly include salaries, bonuses, allowances and subsidies, pension insurance, social insurance and housing funds, labour union fees, employees' education fees and other expenses related to the employees for their services. The Group recognises employee benefits as liabilities during the accounting period when employees rendered the services and allocates the related cost of assets and expenses based on different beneficiaries.

(a)	Bonus plans
	The expected cost of bonus plans is recognised as a liability when the Group has a present legal or constructive obligation as a result of services rendered by employees and a reliable estimate of the obligation can be made.

(b)	Retirement benefit obligations
	The Group primarily pays contributions on a monthly basis to participate in a pension plan organised by the relevant municipal and provincial governments in the PRC. In 2016, the Group made monthly contributions at the rate of 20% (2015: 20%) of the qualified employees' salaries. The municipal and provincial governments undertake to assume the retirement benefit obligations of all existing and future retired employees payable under these plans. The Group has no legal or constructive obligations for further contributions if the fund does not hold sufficient assets to pay all employees the benefit relating to their current and past services.
(c)	Other social insurance and housing funds
	The Group provides other social insurance and housing funds to the qualified employees in the PRC based on certain percentages of their salaries. These percentages are not to exceed the upper limits of the percentages prescribed by the Ministry of Human Resources and Social Security of the PRC. These benefits are paid to social security organisations and the amounts are expensed as incurred. The Group has no legal or constructive obligations for further contributions if the fund does not hold sufficient assets to pay all employees the benefit relating to their current and past services.

(d)

Termination benefit obligations and early retirement benefit obligations

Termination and early retirement benefit obligations are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy and/or early retirement in exchange for these benefits. The Group recognises termination and early retirement benefit obligations when it is demonstrably committed to either: terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal; or providing termination benefits as a result of an offer made to encourage voluntary redundancy and/or early retirement. The specific terms vary among the terminated and early retired employees depending on various factors including position, length of service and district of the employees concerned. Benefits falling due for more than 12 months after the end of the reporting period are discounted to their present values.

2.25	Current and deferred income tax
	The income tax expense for the period comprises current and deferred tax. Share of income tax expense of joint ventures and associates are included in "share of profits and loss of joint ventures and associates". Income tax expense is recognised in profit or loss except to the extent that it relates to items recognised in other comprehensive income or directly in equity. In this case, the tax is also recognised in other comprehensive income or directly in equity, respectively.
	The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the end of the reporting period 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. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

	2.25	Current and deferred income tax (Continued)
		Deferred income tax is provided using the liability method on all temporary differences at the end of reporting period between tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax liabilities are not recognised if they arise from the initial recognition of goodwill; the deferred tax is not accounted for if it arises from the initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred tax is determined using tax rates (and laws) that have been enacted or substantively enacted at the end of the reporting period and are expected to apply when the related deferred tax asset is realised or the deferred tax liability is settled.
		Deferred tax assets are recognised for all deductible temporary differences, the carrying forward of unused tax losses and tax credits. Deferred tax assets are recognised only to the extent that it is probable that future taxable profit will be available against which the temporary differences and the carry forward of unused tax losses and unused tax credits can be utilised.
		Deferred tax liability is provided for all taxable temporary differences arising on investments in subsidiaries, joint ventures and associates, except where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future.
		Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.
	2.26	Perpetual securities
		Perpetual securities are classified as equity if they are non-redeemable, or redeemable only at the issuer's option, and any interests and distributions are discretionary. Interests and distributions on perpetual securities classified as equity are recognized as distributions within equity.
		The perpetual securities issued by the Company are recognized as other equity instruments, and the perpetual securities issued by subsidiary of the Company are recognized as non-controlling interests.

	2.27	Revenue recognition
		The Group recognises revenue when the amount of revenue can be reliably measured, it is probable that future economic benefits will flow to the Group and when specific criteria have been met for each of the Group's activities (see descriptions below).
		(a)	Sales of goods
			Revenue from the sales of goods is recognised when the Group has already transferred the significant risks and rewards of ownership of the goods to the buyers, the Group has retained neither continuing managerial involvement nor control over the goods, it is probable that the economic benefits related to the transaction will flow into the Group, and the revenue and related costs incurred can be measured reliably.
			If the Group is acting solely as an agent, amounts billed to customers are offset against the relevant costs, and the related revenue is reported on a net basis.
		(b)	Rendering of services
			The Group provides machinery processing, transportation and packaging services and other services to third party customers. These services are recognised in the period when the related services are provided.
	2.28	Interest income
		Interest income is recognised using the effective interest method. When a loan or receivable is impaired, the Group reduces the carrying amount to its recoverable amount, being the estimated future cash flows discounted at the original effective interest rate of the instrument, and continues unwinding the discount as interest income. Interest income on impaired loans and receivables is recognised using the original effective interest rate.
	2.29	Dividend income
		Dividend income is recognised when the right to receive payment is established.

	2.30	Leases
		The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement at the inception date. The arrangement is assessed for whether fulfilment of the arrangement is dependent on the use of a specific asset or assets or the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement.
		Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are charged to profit or loss on a straight-line basis over the period of the lease.
		The Group leases certain land use right and property, plant and equipment. Land use right and property, plant and equipment where the Group has substantially all the risks and rewards of ownership are classified as finance leases. Finance leases are capitalised at the lease's commencement at the lower of the fair value of the land use right and the present value of the minimum lease payments.
		Each lease payment is allocated between the liability and finance charges. The corresponding rental obligations, net of finance charges, are included in other long-term payables. The interest element of the finance costs is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The property, plant and equipment acquired under finance leases are depreciated over the shorter of the useful life of the asset and the lease term.
		Regarding the sale and leaseback agreements, the Group treats the sale and leaseback transactions as finance leases, the difference between the carrying amount and the consideration will be deferred and recognized in profit or loss during the useful lives of relevant assets as an adjustment of depreciation expense.

2.	BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)
	2.31	Borrowing costs
		General and specific borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale.
		Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalisation.
		All other borrowing costs are recognised in profit or loss in the period in which they are incurred. Borrowing costs consist of interest and other costs that an entity incurs in connection with the borrowing of funds.
	2.32	Dividend distribution
		Dividend distribution to the Company's shareholders is recognised as a liability in the Group's and Company's financial statements in the period in which the dividends are approved by the Company's shareholders.
	2.33	Provisions
		A provision is recognised when a present obligation (legal or constructive) has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation, provided that a reliable estimate can be made of the amount of the obligation.
		Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate 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 the passage of time is recognised as interest expense.

3.	SIGNIFICANT ACCOUNTING ESTIMATES AND JUDGMENTS
	The preparation of the Group's consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. Uncertainty about these judgments, assumptions and estimates could result in outcomes that require a material adjustment to the carrying amounts of assets or liabilities affected in future periods.
	Judgments
	In the process of applying the Group's accounting policies and preparing the Group's consolidated financial statements, management has made the following judgments, apart from those involving estimates, which have significant effect on the amounts recognised in the consolidated financial statements.
	(a)	Significant influence over an entity in which the Group holds less than 20% of voting rights
		At 31 December 2016, the Group owned a 15% equity interest of Chalco Mineral Resources Co. Ltd. ("Chalco Resources") ("中鋁礦產資源有限公司"). The Group considers that it has significant influence over Chalco Resources even though it owns less than 20% of the voting rights, on the grounds that the Company can appoint one out of the five directors of the board of directors of Chalco Resources.
		At 31 December 2016, the Group owned a 14.62% equity interest of China Rare Earth Co., Ltd. ("China Rare Earth") ("中國稀有稀土有限公司"). The Group considers that it has significant influence over China Rare Earth even though it owns less than 20% of the voting rights, on the grounds that the Group can appoint one out of the seven directors of the board of directors of China Rare Earth.
		At 31 December 2016, the Group owned 17.7% of the voting right of Chinalco Capital Holdings Co., Ltd.* ("Chinalco Capital") ("中鋁資本控股有限公司"). The Group considers that it has significant influence over Chinalco Capital since it can appoint one out of three directors of the board of directors of Chinalco Capital.
		At 31 December 2016, the Group owned a 16% equity interest of Baise New Aluminum Power Co., Ltd. ("New Aluminum Power") ("百色新鋁電力有限公司"). The Group considers that the Group has significant influence over New Aluminum Power even though it owns less than 20% of the voting rights, on the grounds that the Group can appoint one out of the nine directors of the board of directors of New Aluminum Power.

	Judgments (Continued)
	(b)	Entity in which the Group holds more than a majority of voting rights that is not subject to consolidation
		In April 2015, Ningxia Energy and Zhejiang Power Group Co., Ltd.* ("Zhejiang Power") (浙江省能源集團有限公司) jointly established Ningxia Yinxing Power Co., Ltd.* ("Yinxing Power") (寧夏銀星發電有限責任公司). The registered capital of Yinxing Power is RMB800 million, of which Ningxia Energy and Zhejiang Power contributed 51% and 49%, respectively. Ningxia Energy can appoint four out of the seven directors of the board of directors. According to the articles of association of Yinxing Power, most of the resolutions of both shareholders' meeting and board of directors require more than two-thirds of the votes for passing. Accordingly, the directors of the Company consider that Ningxia Energy and Zhejiang Energy have joint control over Yinxing Power, which is accounted for as a joint venture.
	(c)	Consolidation of entities in which the Group holds less than a majority of voting rights
		In December 2016, Yinxing Energy issued shares non-publicly and the equity interest of the Group in Yinxing Energy was diluted to 40.44%. Since the remaining 59.56% of the equity shares in Yinxing Energy are held by large number of individual shareholders, in opinion of the directors of the Company, the Group has control over Yinxing Energy and Yinxing Energy continues to be included in the consolidation scope.

	(c)	Consolidation of entities in which the Group holds less than a majority of voting rights (Continued)
		The Group had 50% equity interest in Shanxi China Huarun Co., Ltd.* ("Shanxi Huarun") ("山西中鋁華潤有限公司"). According to the acting-in-concert agreement entered into by the Group and the other shareholder of Shanxi Huarun, Huarun (Coal) Group Co., Ltd. * ("Huarun (Coal) Group") ("華潤（煤業）集團有限公司"), Huarun (Coal) Group will exercise the shareholders vote in concert with the Group. Accordingly, the directors of the Company consider that the Group had control over Shanxi Huarun and included Shanxi Huarun in the consolidation scope.
	(d)	Lease classification
		As disclosed in note 20, the Group has entered into several sales and lease back agreements with third party lease companies and related party lease companies. The Group assessed the terms in the agreements and considered that the Group had substantially all the risks and rewards of ownership and treated them as finance leases.

* The English name represents the best effort made by the management of the Group in translating its Chinese name as it does not have any official English name.

3.	SIGNIFICANT ACCOUNTING ESTIMATES AND JUDGEMENTS (Continued)
	Estimates and assumptions
	The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Group's assumptions and estimates are based on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising beyond the control of the Group. Such changes are reflected in the assumptions when they occur.
	(a)	Property, plant and equipment and intangible assets - recoverable amount
		In accordance with the Group's accounting policy, each asset or cash-generating unit is evaluated in every reporting period to determine whether there are any indications of impairment. If any such indication exists, an estimate of the recoverable amount is performed and an impairment loss is recognised to the extent that the carrying amount exceeds the recoverable amount. The recoverable amount of an asset or cash-generating unit of assets is measured at the higher of fair value less costs of disposal and value in use.
		Fair value is determined as the amount that would be obtained from the sale of the asset in an arm's length transaction between knowledgeable and willing parties.
		Value in use is also generally determined as the present value of the estimated future cash flows of those expected to arise from the continued use of the asset in its present form and its eventual disposal. Present values are determined using a risk-adjusted pre-tax discount rate appropriate to the risks inherent in the asset. Future cash flow estimates are based on expected production and sales volumes, selling prices (considering current and historical prices, price trends and related factors) and operating costs. This policy requires management to make these estimates and assumptions which are subject to risk and uncertainty; hence there is a possibility that changes in circumstances will alter these projections, which may impact on the recoverable amounts of the assets. In such circumstances, some or all of the carrying value of the assets may be impaired and the impairment would be charged against profit or loss.

3.	SIGNIFICANT ACCOUNTING ESTIMATES AND JUDGEMENTS (Continued)
	Estimates and assumptions (Continued)
	(b)	Property, plant and equipment and intangible assets- estimated useful lives and residual values
		The Group's management determines the estimated useful lives and residual values (if applicable) and consequently the related depreciation/amortisation charges for its property, plant and equipment and intangible assets. These estimates are based on the historical experience of the actual useful lives of property, plant and equipment of similar nature and functions, or based on value-in-use calculations or market valuations according to the estimated periods that the Group intends to derive future economic benefits from the use of intangible assets. Management will increase the depreciation/amortisation charge where useful lives are less than previously estimated, and it will write off or write down technically obsolete or non-strategic assets that have been abandoned or sold.
		Actual economic lives may differ from estimated useful lives and actual residual values may differ from estimated residual values. Periodic review could result in change in depreciable lives and residual values and therefore change in depreciation/amortisation expense in future periods.
	(c)	Estimated impairment of trade and other receivables and inventories
		A provision for impairment of trade and other receivables is established when there is objective evidence that the Group will not be able to collect all amounts due according to the original repayment terms of the receivables. Significant financial difficulties of the debtor, probability that the debtor will enter bankruptcy or financial reorganisation, and default or delinquency in payments are considered as indicators that a trade receivable is impaired. The amount of provision is the difference between the asset's carrying amount and the present value of estimated future cash flows, discounted at the original effective interest rate. Cash flows relating to trade and other receivables are discounted if the effect of discounting is material. The carrying amount of the asset is reduced through the use of an allowance account and the amount of the loss is recognised in profit or loss. When a trade and other receivable is uncollectible, it is written off against the allowance account for trade and other receivables. Subsequent recoveries of amounts previously written off are recognised as income in profit or loss. The impairment is subject to management's assessment at the end of the reporting period, and hence, the provision amount is subject to uncertainty.

3.	SIGNIFICANT ACCOUNTING ESTIMATES AND JUDGEMENTS (Continued)
	Estimates and assumptions (Continued)
	(c)	Estimated impairment of trade and other receivables and inventories (Continued)
		In accordance with the Group's accounting policy, the Group's management tests whether inventories suffered any impairment based on estimates of the net recoverable amount of the inventories. For different types of inventories, it requires the estimation on selling prices, costs of conversion, selling expenses and related tax expense to calculate the net recoverable amount of inventories. For inventories held for executed sales contracts, management estimates the net recoverable amount based on the contracted price; for other inventories, management estimates the realisable future price based on the actual prices during the period from the end of the reporting period to the date that these financial statements were approved for issue by the board of directors of the Company and takes into account the nature and balance of inventories and future estimated price trends. For raw materials and work-in-progress, management has established a model in estimating the net recoverable amount at which the inventories can be realised in the normal course of business after considering the Group's manufacturing cycles, production capacity and forecasts, estimated future conversion costs and selling prices. Management also takes into account the price or cost fluctuations and other related matters occurring after the end of the reporting period which reflect conditions that existed at the end of the reporting period.
		It is reasonably possible that if there is a significant change in circumstances including the Group's business and the external environment, outcomes within the next financial year would be significantly affected.
	(d)	Coal reserve estimates and units-of-production depreciation for coal mining rights
		External qualified valuation professionals evaluate "economically recoverable reserves" based on the reserves estimated by external qualified exploration engineers in accordance with the PRC standards. The estimates of coal reserves are inherently imprecise and represent only the approximate amounts of the coal reserves because of the subjective judgements involved in developing such information. Economically recoverable reserve estimates are evaluated on a regular basis and have taken into account recent production and technical information about each mine.

3.	SIGNIFICANT ACCOUNTING ESTIMATES AND JUDGEMENTS (Continued)
	Estimates and assumptions (Continued)
	(e)	Income tax
		The Group estimates its income tax provision and deferred income taxation in accordance with the prevailing tax rules and regulations, taking into account any special approvals obtained from the relevant tax authorities and any preferential tax treatment to which it is entitled in each location or jurisdiction in which the Group operates. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. The Group recognises liabilities for anticipated tax audit issues based on estimates of whether additional taxes will be due. Where the final tax outcome of these matters is different from the amounts that were initially recorded, the differences will impact on the income tax and deferred income tax provisions in the period in which the determination is made.
		Deferred tax assets are recognised for unused tax losses and deductible temporary differences, such as provision for impairment of receivables, inventories and property, plant and equipment and accruals of expenses not yet deductible for tax purposes, to the extent that it is probable that taxable profits will be available against which the losses deductible temporary difference can be utilised. Significant management judgement is required to determine the amount of deferred tax assets that can be recognised, based upon the likely timing and level of future taxable profits together with future tax planning strategies. An entity shall recognise a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries, associates and joint ventures, except to the extent that both of the following conditions are satisfied:

• the parent, investor or joint venturer is able to control the timing of the reversal of the temporary difference; and

• it is probable that the temporary difference will not reverse in the foreseeable future.

	(e)	Income tax (Continued)
		The Group considers it has recorded adequate current tax provision and deferred income taxes based on the prevailing tax rules and regulations and its current best estimates and assumptions. In the event that future tax rules and regulations or related circumstances change, adjustments to current and deferred income taxation may be necessary which would impact on the Group's results or financial position.
	(f)	Goodwill - recoverable amount
		In accordance with the Group's accounting policy, goodwill is allocated to the Group's operating segments as it represents the lowest level within the Group at which the goodwill is monitored for internal management purposes and is tested for impairment annually by preparing a formal estimate of the recoverable amount. The recoverable amount is estimated as the value in use of the operating segment. Similar considerations to those described above in respect of assessing the recoverable amount of property, plant and equipment also apply to goodwill.

	(g)	Investment in joint ventures and associates – recoverable amount
		In accordance with the Group's accounting policy, each investment in joint ventures and associates is evaluated in every reporting period to determine whether there are any indications of impairment. If any such indication exists, an estimate of the recoverable amount is performed and an impairment loss is recognised to the extent that the carrying amount exceeds the recoverable amount. The recoverable amount of the investment in a joint venture and an associate is measured at the higher of fair value less costs of disposal and value in use.
		Fair value is determined as the amount that would be obtained from the sale of the investment in an arm's length transaction between knowledgeable and willing parties.
		Value in use is also generally determined as the present value of the estimated future cash flows of those expected to arise from the continued use of the asset in its present form and its eventual disposal. Present values are determined using a risk-adjusted pre-tax discount rate appropriate to the risks inherent in the asset. Future cash flow estimates are based on expected production and sales volumes, commodity prices (considering current and historical prices, price trends and related factors) and operating costs. This policy requires management to make these estimates and assumptions which are subject to risk and uncertainty; hence there is a possibility that changes in circumstances will alter these projections, which may impact on the recoverable amounts of the investments. In such circumstances, some or all of the carrying value of the investments may be impaired and the impairment would be charged against profit or loss.

	For the year ended 31 December 2016, the amortisation expenses of intangible assets recognised in profit or loss were analysed as follows:

	2016	2015
Cost of sales	211,325	223,068
General and administrative expenses	32,446	32,030
	243,771	255,098

As at 31 December 2016, the Group has pledged intangible assets with a net carrying value amounting to RMB1,114 million (31 December 2015: RMB1,241 million) for bank and other borrowings as set out in note 24 to the financial statements.

As at 31 December 2016, the Group was in the process of applying for the certificates of mining rights with a carrying value amounting to RMB1,577 million (31 December 2015: RMB1,582 million). There have been no litigations, claims or assessments against the Group for compensation with respect to the use of these rights to date. As at 31 December 2016, the carrying value of these rights only represented approximately 1% of the total asset value of the Group (31 December 2015: 1%). Management considers that it is probable that the Group can obtain the relevant ownership certificates from the appropriate authorities. The directors of the Company are of the opinion that the Group legally owns and has the rights to use the above mining rights, and that there is no material adverse impact on the overall financial position of the Group.

	Impairment tests of goodwill
	The lowest level within the Group at which goodwill is monitored for internal management purposes is the operating segment level. Therefore, goodwill is allocated to the Group's cash generating units ("CGUs") and groups of CGUs according to operating segments. A summary of goodwill allocated to each segment is presented below:

	31 December 2016				31 December 2015
	Alumina		Primaryaluminum		Alumina		Primaryaluminum
Qinghai Branch		—		217,267		—		217,267
Guangxi Branch		189,419		—		189,419		—
Lanzhou Branch		—		1,924,259		—		1,924,259
PT. Nusapati Prima ("PTNP")		15,908		—		14,892		—
		205,327		2,141,526		204,311		2,141,526

The recoverable amount of a CGU is determined based on value-in-use calculations. These calculations use pre-tax cash flow projections based on financial budgets approved by management covering a five-year period. Cash flows beyond the five-year period are extrapolated using the estimated growth rate of 2% (2015: 2%) not exceeding the long-term average growth rate for the businesses in which the CGU operates. Other key assumptions applied in the impairment tests include the expected product price, demand for the products, product costs and related expenses. Management determined these key assumptions based on past performance and their expectations on market development. Furthermore, the Group adopts a pre-tax rate of 12.62% (2015: 12.62%) that reflects specific risks related to CGUs and groups of CGUs as the discount rate. The assumptions above are used in analysing the recoverable amounts of CGUs and groups of CGUs within operating segments.

The directors of the Company are of the view that, based on their assessment, there was no impairment of goodwill as at 31 December 2016 (31 December 2015: no impairment).

6.	PROPERTY, PLANT AND EQUIPMENT (Continued)
	For the year ended 31 December 2016, depreciation expenses recognised in profit or loss are analysed as follows:

	2016	2015
		(restated	)
Cost of sales	6,371,154	6,736,466
General and administrative expenses	180,111	172,524
Selling and distribution expenses	9,530	22,731
	6,560,795	6,931,721

As at 31 December 2016, the Group was in the process of applying for the ownership certificates of buildings with a net carrying value of RMB6,759 million (31 December 2015: RMB5,105 million). There has been no litigations, claims or assessments against the Group for compensation with respect to the use of these buildings as at the date of approval of these financial statements. As at 31 December 2016, the carrying value of these buildings only represented approximately 3.56% of the Group's total asset value (31 December 2015: 3%). Management considers that it is probable that the Group can obtain the relevant ownership certificates from the appropriate authorities. The directors of the Company are of the opinion that the Group legally owns and has the rights to use the above property, plant and equipment, and that there is no material adverse impact on the overall financial position of the Group.

For the year ended 31 December 2016, interest expenses of RMB414 million (2015: RMB522 million (restated)) arising from borrowings attributable to the construction of property, plant and equipment during the year were capitalised at an annual rate ranging from 3.85% to 6.00% (2015: 4.90% to 6.55%) (note 28), and were included in additions to property, plant and equipment.

As at 31 December 2016, the Group has pledged property, plant and equipment at a net carrying value amounting to RMB6,456 million (31 December 2015: RMB6,103 million) for bank and other borrowings as set out in note 24 to the financial statements.

As at 31 December 2016, the carrying value of temporarily idle property, plant and equipment of the Group was RMB2,756 million (31 December 2015: RMB6,257 million).

6.	PROPERTY, PLANT AND EQUIPMENT (Continued)
	The net carrying amounts of the Group's fixed assets held under finance leases included in the total amounts of the machinery and construction in progress at 31 December 2016 were RMB7,200 million (2015: RMB6,154 million (restated)) and RMB194 million (2015: RMB888 million), respectively. The accumulated depreciation of the Group's fixed assets held under finance lease amounted to RMB1,703 million (2015: RMB495 million (restated)).
	Impairment tests for property, plant and equipment
	When any indicators of impairment are identified, property, plant and equipment are reviewed for impairment based on each CGU. The CGU is an individual plant or entity. The carrying values of these individual plants or entities were compared to the recoverable amounts of the CGUs, which were based predominantly on value-in-use. Value-in-use calculations use pre-tax cash flow projections based on financial budgets approved by management covering a five-year period. Cash flows beyond the five-year period are extrapolated using the same cash flow projections of the fifth year. Other key assumptions applied in the impairment tests include the expected product price, demand for the products, product cost and related expenses. Management determined these key assumptions based on past performance and their expectations on market development. Further, the Group adopts a pre-tax rate of 10.16% (2015: 10.16%) that reflects specific risks related to the CGUs as discount rates. The assumptions above are used in analysing the recoverable amounts of the CGUs within operating segments.
	For the CGUs with indicators of impairment identified, the assets were not further impaired during the current year based on the impairment tests (2015: nil).
	In addition to the CGUs for which the impairment was tested based on value-in-use, the Group also assessed the recoverable amounts for the property, plant and equipment about to be disposed or abandoned, and impairment losses of RMB57 million were provided during year ended 31 December 2016 (2015: RMB10 million).

ii.

In December 2016, the directors of the Company approved to use the land use right of Gansu Hualu, a subsidiary of the Company, for commercial development in the future. Accordingly, the Group accounted for the land use right as investment property and adopted the cost model for its subsequent measurement. As at 31 December 2016, the net carrying amount of the land use right was RMB1,156 million and the accumulated depreciation amounted to RMB26 million.

The Group's investment properties consist of land use right to be developed and buildings under operating leases.

As at 31 December 2016, the fair value of the buildings was approximately RMB106 million which was estimated based on the market price of comparable buildings in the nearby area. The directors of the Company estimated that the fair value of the land use right is highly likely to be RMB1,221 million, which was determined based on the transaction prices for similar lands nearby.

11. DEFERRED TAX (CONTINUED)

As at 31 December 2016, the Group has not recognised deferred tax liabilities for taxable temporary differences associated with the investment in a joint venture established in China, which is caused by the undistributed retained earnings and the appreciation value due to loss of control by partial disposal in 2015. The directors of the Company consider that the taxable temporary difference relating to this joint venture will be reversed mainly through future profit distributions or future disposal. Considering the joint venture is established in China, and the profit distribution is non-taxable according to China tax law, there will be no tax consequences from the profit distribution. Furthermore, the Group has no plan to dispose of the equity investment in this joint venture in the foreseeable future, and the Group can control the disposal. Therefore, as at 31 December 2016, the Group did not recognise deferred tax liability relating to the taxable temporary difference associated with investment in this joint venture amounting to RMB1,393 million (31 December 2015: RMB1,407 million).

As at 31 December 2016, the Group has not recognised deferred tax assets of RMB5,489 million (31 December 2015: RMB5,582 million) in respect of accumulated tax losses amounting to RMB21,957 million (31 December 2015: RMB22,328 million) arising in Mainland China that can be carried forward for offsetting against future taxable income, and deferred tax assets of RMB1,915 million (31 December 2015: RMB2,057 million) in respect of deductible temporary differences amounting to RMB7,660 million (31 December 2015: RMB8,227 million) as it was considered not probable that those assets would be realised. The above tax losses will expire in one to five years if not utilised.

As at 31 December 2016, the expiry profile of these unprovided tax losses was analysed as follows:

	31 December	31 December
	2016	2015
Expiring in
2016	—	63,812
2017	4,473,661	3,812,061

2021	1,035,068	N/A
	21,956,756	22,327,636

As at 31 December 2016, deferred tax assets amounting to RMB1,427 million (31 December 2015: RMB1,363 million) were recognised for tax losses and deductible temporary differences carried forward to the extent that the realisation of the related tax benefit is probable. The recognition of these deferred tax assets is supported by forecast of future taxable profits available to the Group.

Based on past experience, the directors of the Company are of the opinion that no provision for impairment is necessary in respect of these balances as there has not been a significant change in credit quality and the balances are still considered recoverable within 12 months as at 31 December 2016.

Included in the Group's trade receivables are amounts due from the Group's joint ventures of RMB38 million (31 December 2015: RMB28 million), which are repayable on credit terms similar to those offered to the major customers of the Group.

As at 31 December 2016, the Group had pledged trade receivables amounting to RMB36 million (31 December 2015: RMB360 million) and notes receivable amounting to RMB34 million (31 December 2015: RMB27 million) for bank and other borrowings as set out in note 24 to the financial statements.

	Notes: (Continued)
	(f)	Secured interest-bearing loans and borrowings
.		The assets pledged for bank and other borrowings were set out in note 24 to the financial statements.
	(g)	Gold leasing arrangements
.		On 6 June 2016, the Company entered into a gold leasing operational agreement, four gold leasing agreements and a general hedging agreement with BOCOM, pursuant to which the Company developed gold leasing for working capital financing purposes.
.		According to the gold leasing operational agreement and gold leasing agreements, the Group leased from BOCOM standard gold with fineness of Au99.99 for 12 months with annual lease fee rates from 3.61% to 3.70%. Then, the Group sold the leased gold back to BOCOM at the predetermined price and received cash of RMB3,000 million. The Group has paid an upfront lease fee amounting to RMB86.4 million at the beginning of the lease period. Upon the expiry of the leasing term, the Group shall purchase the same amount of gold with fineness of Au99.99 from BOCOM at the predetermined price pursuant to the general hedging agreement, and return the standard gold with same quality as those under the gold leasing agreements.
		The directors of the Company are of view that the gold leasing operational agreement, gold leasing agreements and the general hedging agreement are planned, determined and operated as an integrated transaction, through which the Group is free from the risks of gold price fluctuations, and therefore, should be accounted for as loans from BOCOM with fixed interest rates.

During the years ended 31 December 2016 and 2015, the Group's significant transactions with entities directly or indirectly owned or controlled by the government through its agencies, affiliates or other organisations (collectively "State-owned Enterprises" ("SOEs")) (excluding Chinalco and its subsidiaries) constituted a large portion of its sales of goods and purchases of raw materials, electricity, property, plant and equipment and services.

The Group has also established pricing policies for rendered services and such pricing policies do not depend on whether or not the customers are SOEs.

36. FINANCIAL AND CAPITAL RISK MANAGEMENT

36.1	Financial risk management
	The Group's activities expose it to a variety of financial risks, including market risk (including foreign currency risk, cash flow and fair value interest rate risk and commodity price risk), credit risk and liquidity risk. The Group's overall risk management program focuses on the unpredictability of financial markets and seeks to minimise the potential adverse effects on the Group's financial performance.
	Risk management is carried out by the treasury management department (the "Group Treasury") under policies approved by the board of directors of the Company. The Group Treasury identifies, evaluates and hedges financial risks through close co-operation with the Group's operating units.

(a) Market risk

(i)	Foreign currency risk
	Foreign currency risk primarily arises from certain significant foreign currency deposits, trade and notes receivables, trade and notes payables, receivable from a subsidiary of Chinalco due to disposal of an entity in the preceding year, advances paid to suppliers, and short-term and long-term loans denominated in United States dollars ("USD"), Australian dollars ("AUD"), Euro ("EUR"), Japanese yen ("JPY"), Indonesian Rupiah ("IDR") and Hong Kong dollars ("HKD"). Related exposures are disclosed in notes 14, 15, 16, 19, 22, 23 and 40 to the financial statements, respectively. The Group Treasury closely monitors the international foreign currency market on the change of exchange rates and takes these into consideration when investing in foreign currency deposits and borrowing loans. As at 31 December 2016, the Group only had significant exposure to USD.
	As at 31 December 2016, if RMB had strengthened/weakened by 5% against USD with all other variables held constant, the profit for the year would have been approximately RMB269 million lower/higher (2015: RMB177 million lower/higher), mainly as a result of foreign exchange gains and losses arising from translation of USD-denominated borrowings and receivables. Profit was more sensitive to the fluctuation in the RMB/USD exchange rates in 2016 than in 2015, mainly due to the increase in the USD denominated cash and receivables.

36. FINANCIAL AND CAPITAL RISK MANAGEMENT (Continued)

36.1 Financial risk management (Continued)

(a) Market risk (Continued)

(i)	Foreign currency risk (Continued)
	As the assets and liabilities denominated in other foreign currencies other than USD were relatively minimal to the total assets and liabilities of the Group, the directors of the Company are of the opinion that the Group was not exposed to any significant foreign currency risk arising from these foreign currency denominated assets and liabilities as at 31 December 2016 and 2015.
(ii)	Interest rate risk
	As at 31 December 2016, as the Group had no significant interest-bearing assets except for bank deposits (note 16), entrusted loans (note 15), receivables arising from disposal of business (note 15), a prepayment paid to a supplier (note 15) and a loan to Shanxi Huaxing (note 12), the Group's income and operating cash flows are substantially independent of changes in market interest rates.
	Most of the bank deposits are maintained in savings and time deposit accounts in the PRC. The interest rates are regulated by the People's Bank of China and the Group Treasury closely monitors the fluctuation on such rates periodically. The interest rates of entrusted loans and a deposit paid to a supplier are fixed, the interest rate of the receivables from disposal of businesses to Chinalco is at the rate of one-year bank loan determined by the People's Bank of China at the payment date and the interest rate of the receivables from disposal of an entity to a subsidiary of Chinalco is LIBOR plus 0.9%. As the interest rates applied to the deposits and receivables from disposal of businesses were relatively low and the interest rates applied to the entrusted loans and a prepayment paid to a supplier were fixed, the directors of the Company are of the opinion that the Group was not exposed to any significant interest rate risk for its financial assets held as at 31 December 2016 and 2015.

36. FINANCIAL AND CAPITAL RISK MANAGEMENT (Continued)

36.1 Financial risk management (Continued)

(a) Market risk (Continued)

(ii)	Interest rate risk (Continued)
	The interest rate risk for the Group's financial liabilities primarily arises from interest-bearing loans. Loans borrowed at floating interest rates expose the Group to cash flow interest rate risk. The exposures to these risks are disclosed separately in note 19. The Group enters into debt obligations to support general corporate purposes including capital expenditures and working capital needs. The Group Treasury closely monitors market interest rates and maintains a balance between variable rate and fixed rate borrowings in order to reduce the exposures to the interest rate risk described above.
	As at 31 December 2016, if interest rates had been 100 basis points (31 December 2015: 100 basis points) higher/lower for bank and other loans borrowed at floating interest rates with all other variables held constant, net profit for the year would have been RMB479 million lower/higher (2015: RMB508 million (restated)), respectively, mainly as a result of the higher/lower interest expense on floating rate borrowings.
	The fair value interest rate risk of the Group mainly arises from long-term bonds, medium-term notes and short-term bonds issued at fixed rates. As the fluctuation of comparable interest rates of corporate bonds with similar terms was relatively low, the directors of the Company are of the opinion that the Group is not exposed to any significant fair value interest rate risk for its fixed interest rate borrowings held as at 31 December 2016 and 2015.
(iii)	Commodity price risk
	The Group uses futures and option contracts to reduce its exposure to fluctuations in the price of primary aluminum and other products. The Group uses the futures contract for hedging other than speculation. With reference to the hedgings of primary aluminum, production company hedges the output of primary aluminum and trading company hedges the quantities of buyout and self-supporting.

36.1 Financial risk management (Continued)

(a) Market risk (Continued)

(iii)	Commodity price risk (Continued)
	The Group uses mainly futures contracts and option contracts traded on the Shanghai Futures Exchange and London Metal Exchange ("LME") to hedge against fluctuations in primary aluminum prices. As at 31 December 2016, the fair values of the outstanding futures contracts amounting to RMB55 million (31 December 2015: RMB2 million) and RMB3 million (31 December 2015: RMB11 million) were recognised in financial assets and financial liabilities at fair value through profit or loss, respectively. As at 31 December 2016, the fair value of the outstanding options contracts amounting to RMB0.1 million (31 December 2015: RMB151 million) was recognised in financial liabilities at fair value through profit or loss.
	As at 31 December 2016, if the commodity futures prices had increased/decreased by 3% (31 December 2015: 3%) and all other variables held constant, profit for the year would have changed by the amounts shown below:

	2016	2015
Primary aluminum	Decrease/increase RMB6.761 million	Decrease/increase RMB43.776 million
Copper	Decrease/increase RMB4.085 million	Decrease/increase RMB1.736 million

36.1 Financial risk management (Continued)

(b)	Credit risk
	Credit risk arises from balances with banks and financial institutions, short-term investments, trade and notes receivables, other current and non-current receivables as well as credit exposures of customers, including outstanding receivables and committed transactions. The carrying amounts of short-term investments and these receivables included in notes 10, 12, 14, and 15 represent the Group's maximum exposure to credit risk in relation to its financial assets. The Group also provided financial guarantees to certain subsidiaries, a joint venture as well as a third party. The guarantees to joint ventures and an associate mentioned in note 35 represented the Group's maximum exposure to credit risk in relation to its guarantees to a joint venture. As at 31 December 2016, balance of the guarantees provided to a third party amounted to RMB8 million.
	The Group maintains substantially all of its bank balances and cash and short-term investments in several major state-owned banks in the PRC. With strong support from the PRC government to these state-owned banks, the directors of the Company are of the opinion that there is no significant credit risk on such assets being exposed to losses.
	With regard to receivables, the marketing department assesses the credit quality of the customers and their related parties, taking into account their financial positions, past experience and other factors. The Group performs periodic credit evaluations of its customers and considers that adequate provision for impairment of receivables has been made in the financial statements. Management does not expect any further losses from non-performance by these counterparties. The Group holds collateral for some entrusted loans. As at 31 December 2016, the Group had receivables amounting to RMB4,470 million from Chinalco and its subsidiaries which arose from the disposal of business. Chinalco and its subsidiaries have settled the receivables and the related interest thereof in accordance with the payment terms. Therefore, the Group considers that there is no material credit risk related to the above-mentioned receivables.
	For the year ended 31 December 2016, revenues of approximately RMB30,940 million (2015: RMB31,818 million) were derived from entities directly or indirectly owned or controlled by the PRC government including Chinalco. There were no other individual customers from whom the Group has derived revenue of more than 10% of the Group's revenue during the years ended 31 December 2016 and 2015. Thus, the directors of the Company are of the opinion that the Group was not exposed to any significant concentration of credit risk as at 31 December 2016 and 2015.

(c)	Liquidity risk
	Cash flow forecast is performed in the operating entities of the Group and aggregated by the Group Treasury. The Group Treasury monitors rolling forecasts of the Group's liquidity requirements to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn committed borrowing facilities at all times so that the Group does not breach borrowing limits or covenants (where applicable) on any of its borrowing facilities. This forecast takes into consideration of the Group's debt financing plans, covenant compliance, compliance with internal balance sheet ratio targets and, if applicable, external regulatory or legal requirements, for example, currency restrictions.
	As at 31 December 2016, the Group had total banking facilities of approximately RMB134,235 million of which amounts totalling RMB61,980 million have been utilised as at 31 December 2016. Banking facilities of approximately RMB67,510 million will be subject to renewal during the next 12 months. The directors of the Company are confident that such banking facilities can be renewed upon expiration based on their past experience and good credit standing.
	In addition, as at 31 December 2016, the Group had credit facilities through its futures agent at the LME amounting to USD120 million (equivalent to RMB832 million) (31 December 2015: USD120 million (equivalent to RMB799 million)), of which USD50 million (equivalent to RMB344 million) (31 December 2015: USD58 million (equivalent to RMB376 million)) has been utilised. The futures agent has the right to adjust the related credit facilities.
	Management also monitors rolling forecasts of the Group's liquidity reserve on the basis of expected cash flows.

(b)	Fair value and fair value hierarchy (Continued)
	Fair value (Continued)
	Management has assessed that the fair values of cash and cash equivalents, restricted cash and time deposits, trade and notes receivables, financial assets included in other current assets, entrusted loans, trade and notes payables, financial liabilities included in other payables and accrued liabilities, short-term and the current portion of interest-bearing loans and borrowings, interest payable and the current portion of long-term payables approximate to their carrying amounts largely due to the short term maturities of these instruments.
	The fair values of the financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The following methods and assumptions were used to estimate the fair values:

• The fair values of the financial assets included in other non-current assets and financial liabilities included in other non-current liabilities have been calculated by discounting the expected future cash flows using rates currently available for instruments on with similar terms, credit risk and remaining maturities.

• The fair values of long-term interest-bearing loans and borrowings have been calculated by discounting the expected future cash flows using rates currently available for instruments with similar terms, credit risk and remaining maturities.

The Group's own non-performance risk for financial liabilities included in other non-current liabilities and long-term interest-bearing loans and borrowings as at 31 December 2016 was assessed to be insignificant.

36.3 Capital risk management

The Group's capital management objectives 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, and to maintain an optimal capital structure to reduce the cost of capital.

In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, issue new shares or sell assets to reduce debts.

Consistent with other entities in the industry, the Group monitors capital on the basis of its gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total liabilities (excluding deferred tax liabilities, income tax payable and deferred government grants) less restricted cash, time deposits and cash and cash equivalents. Total capital is calculated as equity, as shown in the consolidated statement of financial position, plus net debt less non-controlling interests.

During 2016, the change in sales prices of the Group's primary products has advantageous impacted on the profitability of the Group. The gearing ratio as at 31 December 2016 is as follows:

	31 December		31 December
	2016		2015

Total liabilities (excluding deferred tax liabilities, income tax payable and deferred government grants)	131,681,814		137,585,822
