Its operating results achieved profitability for three consecutive years and the risk resistance capacity was continuously enhanced.

Due to the impacts of the COVID-19 epidemic and the plunge of oil prices in 2020, oil companies reduced expenditure in upstream exploration and exploitation. The workload of the Company in the main profession decreased year-on-year while the expenses in epidemic prevention increased, resulting in a year-on-year decrease of 0.7 percentage point in the gross profit margin of the principal business. Financial expenses recorded a year-on-year increase of RMB250 million due to exchange rate fluctuations. Due to the abovementioned factors, the Company's consolidated revenue was RMB68,073,394,000, representing a year-on-year decrease of 2.6%, and net profit attributable to shareholders of the Company amounted to RMB78,978,000, representing a year-on-year decrease of 91.4%. Basic earnings per share was RMB0.004, representing a year-on-year decrease of 91.7%.

The directors of the Company have performed an assessment that operating cash inflows in the next twelve months is expected, and most of the Group's borrowings are sourced from Sinopec Group and its subsidiaries, where the Group maintains ongoing good relationship with these companies, which enables the Group to secure sufficient financial support from these companies. In December 2020, the Group obtained a line of credit of RMB16 billion and USD 0.6 billion (Total: approximately RMB20.9 billion), and line of credit promissory note of RMB10 billion from the Sinopec Group's subsidiaries.

To obtain sufficient credits facilities, the Group will diversify its source of finance by exploring and developing good relationship with listed and state-owned financial institutions. The directors of the Group are in the opinion that the above measures are sufficient to meet with the expected liquidity, daily operation and capital requirements and considered that going concern basis is appropriate for the preparation of these consolidated financial statements.

Basis of preparation

The consolidation financial statements set out in this report have been prepared in accordance with International Financial Reporting Standards ("IFRSs") issued by the International Accounting Standards Board (the "IASB"). These consolidation financial statements also comply with the applicable disclosure requirements of the Hong Kong Companies Ordinance and the applicable disclosure provisions of the Rules Governing the Listing of Securities on the Hong Kong Stock Exchange (the "Listing Rules").

The consolidation financial statements have been prepared under the historical cost convention, as modified by the revaluation of financial assets at fair value through other comprehensive income, which are carried at fair value.

The preparation of consolidation financial statements in conformity with IFRSs requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the accounting policies of the Group. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements.

NEW AND AMENDED IFRSs

The IASB has issued a number of amended IFRSs. The Group has adopted all these amended IFRSs, which are relevant to the Group's operations and effective for the Group's consolidated financial statements for the accounting period beginning on or after 1 January 2020:

Amendments to IFRS 3

Amendments to IFRS 9, IAS 39 and IFRS 7

Interest Rate Benchmark Reform Definition of Material

2019 Covid-19-Related Rent ConcessionsOther than as noted below, the adoption of the amended IFRSs had no material impact on how the results and financial position for the current and prior periods have been prepared and presented.

Application of Amendments to IFRS 16 "2019 COVID-19-Related Rent Concessions"

Rent concessions relating to lease contracts that occurred as a direct consequence of the COVID-19 pandemic, the Group has elected to apply the practical expedient not to assess whether the change is a lease modification if all of the following conditions are met:

-

the change in lease payments results in revised consideration for the lease that is substantially the same as, or less than, the consideration for the lease immediately preceding the change;

- any reduction in lease payments affects only payments originally due on or before 30 June 2021;

-

and there is no substantive change to other terms and conditions of the lease.

A lessee applying the practical expedient accounts for changes in lease payments resulting from rent concessions the same way it would account for the changes applying IFRS 16 "Leases " if the changes were not a lease modification. Forgiveness or waiver of lease payments are accounted for as variable lease payments. The related lease liabilities are adjusted to reflect the amounts forgiven or waived with a corresponding adjustment recognised in the profit or loss in the period in which the event occurs.

The Group has early applied the amendment and the application has no impact to the opening retained profits at 1 January 2020. During the current year, there was no COVID-19-related rent concession occurred and had no impact on the disclosures or the amounts recognised in the consolidated financial statements of the Group.

As at 31 December 2020 and 2019, the Group's notes and trade receivables were approximately their fair value. All notes receivables of the Group are bank's acceptance bills

and commercial acceptance bills and usually collected within six months from the date of issue. As at 31 December 2020 and 2019, none of the Group's notes receivables were pledged

as collateral or overdue.

The Group usually provides customers with credit term in the range of 90 to 180 days. For the settlement of trade receivables from provision of services, the Group usually reaches an agreement on the term of each payment with the customer by taking into account factors such as, among other things, the credit history of the customer, its liquidity position and the

Group's working capital needs, which varies on a case-by-case basis that requires the judgment and experience of the management. The Group does not hold any collateral as security.

(a)Specific reserve

Under PRC ASBE, accrued production safety fund is recognised as expense in profit or loss and separately recorded as a specific reserve in shareholders' equity according to the national regulation. As using production safety fund, if it is profit or loss related, the cost of expenditure is directly charged against the specific reserves. While if it is capital expenditure related, the cost of fixed asset is offset against the specific reserves and the same amount of accumulated depreciation is recognised, then the fixed asset is no longer depreciated in its useful life. Under IFRS, these expenses are recognised in profit or loss as and when incurred. Relevant capital expenditure are recognised as property, plant and equipment and depreciated according to the relevant depreciation method.
