The group and separate company annual financial statements as at and for the year ended 31 December 2022 have been prepared under the supervision of Mr PA Koppeschaar CA(SA), SAICA registration number: 00038621. The principal accounting policies of Exxaro Resources Limited (the company) and its entities (the group) as well as the disclosures made in these annual financial statements comply with IFRS and IFRIC interpretations, effective for the financial year, as well as the SAICA Financial Reporting Guidelines (as issued by the Accounting Practices Committee), the Financial Reporting Pronouncements (as issued by the Financial Reporting Standards Council), the Companies Act (applicable to companies reporting under IFRS) and the Listings Requirements.
The annual financial statements are prepared on the historical cost basis, except for the revaluation to fair value of financial instruments, share-based payments and biological assets. The annual financial statements are prepared on the going-concern basis.
The annual financial statements are presented in South African rand, which is the company's functional and presentation currency. However, the group measures the transactions of each of its material operations using the functional currency determined for that specific entity, which, in most instances, is the currency of the primary economic environment in which the operation conducts its business.
Management considers key financial metrics and loan covenant compliance in its approved medium-term budgets, together with its existing term facilities, to conclude that the going-concern assumption used in compiling the annual financial statements is relevant.
The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the group's accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant, are disclosed within the relevant chapters.
The accounting policies applied for 2022 are consistent with those applied in 2021, except for the adoption of new or amended standards as set out below.
The group annual financial statements present the consolidated financial position and changes therein, operating results and cash flow information of the company and its subsidiaries as those of a single entity.
Judgements, apart from those involving estimates, have been made by management in the process of applying the accounting policies. Details of these judgements have been included within the relevant chapters.
Key assumptions concerning the future, and other key sources of estimation uncertainty at the financial year end, may have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year if the assumption or estimation changes significantly. The financial information on which some of the assumptions are based has not been reviewed nor reported on by the independent external auditors. Details of key assumptions and key sources of estimation uncertainty have been included within the relevant chapters.
The financial reporting impact of the Russian-Ukraine conflict has been assessed by management and factored in as a consideration in making relevant estimates and assumptions, in particular impairment assessments.
The coal price and rand/US$ exchange rate assumptions used to forecast future cash flows for impairment assessment purposes have been updated to consider the short-term observable impact of the Russian-Ukraine conflict, as well as the forecasted medium and longer-term impact on the world economy and commodity prices.
