NOTES TO THE INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

For the six months ended 30 June 2018

China Eastern Airlines Corporation Limited (the “Company”), a joint stock company limited by shares, was established in the People’s Republic of China (the “PRC”) on 14 April 1995. The address of the Company’s registered office is 66 Airport Street, Pudong International Airport, Shanghai, the PRC. The Company and its subsidiaries (together, the “Group”) are principally engaged in the operation of civil aviation, including the provision of passenger, cargo, mail delivery, tour operations and other extended transportation services.

In the opinion of the directors, the holding company and ultimate holding company of the Company is China Eastern Air Holding Company Limited (“CEA Holding”), a state-owned enterprise established in the PRC.

The A shares, H shares and American Depositary Shares are listed on the Shanghai Stock Exchange, The Stock Exchange of Hong Kong Limited and The New York Stock Exchange, respectively.

The unaudited interim condensed consolidated financial statements were approved for issue by the Company’s Board on 30 August 2018.

The unaudited interim condensed consolidated financial statements, comprising interim condensed consolidated statement of financial position as at 30 June 2018, interim condensed consolidated statement of profit or loss and other comprehensive income, interim condensed consolidated statement of changes in equity and interim condensed consolidated statement of cash flows for six months ended 30 June 2018 (collectively refer to as the ”interim financial information”), have been prepared in accordance with International Accounting Standard (“IAS”) 34 “Interim Financial Reporting”. The interim financial information does not include all the information and disclosures required in the annual financial statements and should be read in conjunction with the annual financial statements for the year ended 31 December 2017, which were prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standard Board (“IASB”).

As at 30 June 2018, the Group’s current liabilities exceeded its current assets by approximately RMB55.15 billion. In preparing the interim financial information, the Board conducts adequate and detailed review over the Group’s going concern ability based on the current financial situation.

The Board has taken actions to deal with the situation that current liabilities exceeded its current assets, and the Board is confident that the Group has obtained adequate credit facility from the banks to support the floating capital. As at 30 June 2018 the Group had total unutilised credit facilities of approximately RMB44.20 billion from banks.

Based on the bank facility obtained by the Group, the past record of the financing and the good working relationship with major banks and financial institutions, the Board considers that the Group will be able to obtain sufficient financing to enable it to operate, as well as to meet its liabilities as and when they become due, and the capital expenditure requirements for the upcoming twelve months. Accordingly, the Board believes that it is appropriate to prepare these financial statements on a going concern basis without including any adjustments that would be required should the Company and the Group fail to continue as a going concern.

The accounting policies adopted in the preparation of the interim condensed consolidated financial statements are consistent with those followed in the preparation of the Group’s annual consolidated financial statements for the year ended 31 December 2017, except for the adoption of new standards and interpretations effective as of 1 January 2018. The Group has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective.

This note explains the impact of the adoption of IFRS 9 “Financial Instruments” (“IFRS 9”) and IFRS 15 “Revenue from Contracts with Customers” (“IFRS 15”) on the Group’s financial information and the new accounting policies that have been applied from 1 January 2018, where they are different to those applied in prior periods. Certain of the Group’s accounting policies have been changed to comply with the adoption of IFRS 9 and IFRS 15.

3.1 Impact on the financial information

As explained in note 3.2 and 3.3 below, IFRS 9 and IFRS 15 were generally adopted by the Group without restating comparative information. As a result of the changes in the entity’s accounting policies, certain reclassifications and adjustments are therefore not reflected in the restated statement of financial position as at 31 December 2017, but are recognised in the opening statement of financial position on 1 January 2018.

The following tables show the adjustments recognised for each individual line item. Line items that were not affected by the changes have not been included. The adjustments are explained in more detail by standard below.

Impact on the statement of financial position (increase/(decrease)) as at 1 January 2018:

3.2 Adoption of IFRS 9 Financial Instruments

IFRS 9 Financial Instruments — Impact of adoption

IFRS 9, “Financial instruments”, addresses the classification, recognition and measurement of financial assets and financial liabilities, introduces new rules for hedge accounting and a new impairment model for financial assets. The adoption of IFRS 9 has resulted in changes in the Group’s accounting policies for classification, recognition and measurement of financial assets and financial liabilities and impairment of financial assets.

Classification and measurement

On 1 January 2018 (the date of initial application of IFRS 9), the Group’s management has assessed which business models apply to the financial assets held by the Group and has classified its financial instruments into the appropriate IFRS 9 measurement categories including those to be measured subsequently at fair value (either through other comprehensive income, or through profit or loss) and those to be measured at amortised cost.

10

3.2 Adoption of IFRS 9 Financial Instruments (continued)

IFRS 9 Financial Instruments — Impact of adoption (continued)

Reclassification from available-for-sale investments to equity instruments at fair value through other comprehensive income (“FVOCI”)

The Group invested in a number of equity investments at a total cost of RMB107 million and those investments was classified as available-for-sale stated at cost under previous standard IAS 39. With the adoption of IFRS 9, those investments does not meet the IFRS 9 criteria for classification at amortised cost, because their cash flows do not represent solely payments of principal and interest. Therefore, those equity investments are classified as financial asset measured at fair value and the group elected to present any changes in the fair value in other comprehensive income (“FVOCI”), because those investments are held as long-term strategic investments that are not expected to be sold in the short to medium term.

As a result of the adoption of IFRS 9, the above available-for-sale investments has been fair valued as at 1 January 2018 by the management. The difference between the fair value and the carrying amount of those investments as at 1 January 2018 is approximately RMB895 million, and therefore relevant adjustment was recorded to opening equity.

Reclassification from available-for-sale investments to equity instrument at fair value through profit or loss (“FVPL”)

The Group holds certain listed stock shares and this investment was classified as available-for-sale stated at fair value under previous standard IAS 39. With the adoption of IFRS 9, the management reevaluate the intention of possession of this investment, as the management intends to sell this investment in the short to medium term. Therefore, the Group elected to classify this investment as financial asset measured at fair value and present any changes in the fair value in profit or loss (“FVPL”).

Summary of effects resulting from adoption of IFRS 9 is as follows:

Impairment of financial assets

The new impairment model requires the recognition of impairment provisions based on expected credit losses (ECL) rather than only incurred credit losses as is the case under IAS 39. The Group has one type of financial assets measured at amortised cost that are subject to IFRS 9’s new expected credit loss model:

11

3.2 Adoption of IFRS 9 Financial Instruments (continued)

IFRS 9 Financial Instruments — Impact of adoption (continued)

Impairment of financial assets (continued)

The Group was required to revise its impairment methodology under IFRS 9 for trade and other receivable. The Group applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables and other receivables.

The Group established expected credit losses model based on historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment. The adoption of the ECL requirements of IFRS 9 resulted in increases in impairment allowances of the Group’s trade and other receivables. The increase in allowance resulted in adjustment to opening equity amounting to RMB31 million.

3.3 Adoption of IFRS 15 Revenue from Contracts with Customers

IFRS 15 Revenue from Contracts with Customers — Impact of adoption

IFRS 15, “Revenue from contracts with customers” (“IFRS 15”) deals with revenue recognition and establishes principles for reporting useful information to users of financial statements about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. Revenue is recognised when a customer obtains control of a good or service and thus has the ability to direct the use and obtain the benefits from the good or service. The standard replaces IAS 18 “Revenue” and IAS 11 “Construction contracts” and related interpretations.

Prior to the adoption of IFRS 15, the Group used residual method to allocate a portion of ticket sales to the mileage points issued in connection with the flights, which were valued based on the estimated redemption value. Revenue is recognised when the miles have been redeemed and used or for miles that expire unused at the expiration date. IFRS 15 requires the Group to apply relative stand-alone selling price approach to allocate a portion of sales to the mileage points issued and recognises in contract liabilities and frequent flyer program liabilities. The application of a relative selling price approach lowers the contract liabilities and frequent flyer program liabilities.

The Group charges customers to make changes to air tickets. The process of changing the customer’s itinerary generally will be regarded as a contract modification under IFRS 15 instead of considered as no additional goods or services transferred to the customer prior to the adoption of IFRS 15 and recognised in other revenue at the time of the ticket is changed. Under IFRS 15, change fees is recognised in passenger revenue when transportation is provided.

Passenger ticket breakage is defined as the tickets for which the passenger will not use and will expire unused. Prior to the adoption of IFRS 15, the Group recognised revenue from the ticket breakage upon expiration of the ticket. Under IFRS 15, the Group recognises the estimated breakage in proportion to revenue recognised for tickets acquired during the same period using a portfolio based approach.

12

The Group’s activities expose it to a variety of financial risks: market risk (including currency risk, fair value interest rate risk, cash flow interest rate risk and fuel price risk), credit risk, and liquidity risk. The Group’s overall risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the Group’s financial performance. The Group uses derivative financial instruments to manage risk exposures whenever management considers necessary.

The interim financial information does not include all financial risk management information and disclosures required in the annual financial statements, and should be read in conjunction with the Group’s annual financial statements for the year ended 31 December 2017.

There have been no changes in the risk management department since the 2017 year end or in any risk management policies.

Liquidity risk

The Group’s primary cash requirements are for day-to-day operations, additions of and upgrades to aircraft, engines and flight equipment and repayments of related borrowings. The Group finances its working capital requirements through a combination of funds generated from operations and borrowings including bank loans, debentures and bonds (both short-term and long-term). The Group generally finances the acquisition of aircraft through long-term finance leases or bank loans.

The table below analyses the Group’s financial liabilities that will be settled into relevant maturity groupings based on the remaining period at the reporting date to the contractual maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows.

13

Financial instruments not measured at fair value

The carrying amounts and fair values of the Group’s financial instruments, other than those with carrying amounts that reasonably approximate to fair values, were as follows:

Management has assessed that the fair values of cash and cash equivalents, restricted bank deposits and short-term bank deposits, trade and notes receivables, trade and bills payables, financial assets included in prepayments and other receivables, financial liabilities included in other payables and accruals, short-term bank borrowings and short-term guaranteed bonds approximate to their carrying amounts largely due to the short term maturities of these instruments.

The fair values of the deposits relating to aircraft held under operating leases included in other non-current assets, long-term borrowings and obligations under finance leases have been measured using significant observable inputs and calculated by discounting the expected future cash flows using rates currently available for instruments with similar terms, credit risk and remaining maturities.

Financial instruments measured at fair value

The Group enters into derivative financial instruments, including Foreign exchange forward contracts and interest rate swaps with various counterparties, principally financial institutions with high credit ratings.

Derivative financial instruments are measured using valuation techniques similar to forward pricing and swap models, using present value calculations. The models incorporate various market observable inputs including the foreign exchange spot and forward rates and interest rate curves. As at 30 June 2018, the marked to market value of the derivative asset position is net of a credit valuation adjustment attributable to derivative counterparty default risk. The changes in counterparty credit risk had no material effect on the hedge effectiveness assessment for derivatives designated in hedge relationship and other financial instruments recognised at fair value.

Fair value hierarchy

The following tables illustrate the fair value measurement hierarchy of the Group’s financial instruments:

Assets and liabilities measured at fair value:

As at 30 June 2018

15

As at 31 December 2017

Available-for-sale investments and partial equity instruments are listed A share and H share stock investments, of which the fair value was measured based on quoted market prices at the reporting dates. The rest of the equity instruments are non-listed shares, mainly of which the fair value was measured using market approach at the reporting dates.

The fair values of derivative financial instruments are determined by using valuation techniques. These valuation techniques use applicable models and maximise the use of observable market data where it is available and also use quoted market prices or dealer quotes for reference.
