Areas of judgement:

The depreciation methods, estimated remaining useful lives and residual values are reviewed at least annually. The estimation of the useful lives of property, plant and equipment is based on historic performance as well as expectations about future use and the impact of climate change and therefore requires a significant degree of judgement to be applied by management. The remaining useful lives of property, plant and equipment have been reassessed considering the Group’s targeted reduction in GHG emissions and remain appropriate.

Accounting policies:

Property, plant and equipment

Property, plant and equipment is stated at cost less accumulated depreciation and accumulated impairment losses. Land is not depreciated.

When plant and equipment comprises major components with different useful lives, these components are accounted for as separate items.

Depreciation of mineral assets on producing oil and gas properties is based on the units-of-production method calculated using estimated proved developed reserves. The natural oil and gas reserves are calculated using a methodology designed to be compliant with SEC Regulations S-K.

Life-of-mine coal assets are depreciated using the units-of-production method and are based on proved and probable reserves assigned to that specific mine (accessible reserves) or complex which benefits from the utilisation of those assets. The proved and probable reserves are determined using the SAMREC code. Other coal mining assets are depreciated on the straight-line method over their estimated useful lives.

Depreciation of property acquisition costs, capitalised as part of mineral assets in property, plant and equipment, is based on the units-of-production method calculated using estimated proved reserves.

Property, plant and equipment, other than mineral assets, is depreciated to its estimated residual value on a straight-line basis over its expected useful life.

Assets under construction

Assets under construction include land and expenditure capitalised for work in progress in respect of activities to develop, expand or enhance items of property, plant and equipment. The cost of self-constructed assets includes expenditure on materials, direct labour and an allocated proportion of project overheads. Cost also includes the estimated costs of dismantling and removing the assets and site rehabilitation costs to the extent that they relate to the construction of the asset as well as gains or losses on qualifying cash flow hedges attributable to that asset. When regular major inspections are a condition of continuing to operate an item of property, plant and equipment, and plant shutdown costs will be incurred, an estimate of these shutdown costs are included in the carrying value of the asset at initial recognition. Land acquired, as well as costs capitalised for work in progress in respect of activities to develop, expand or enhance items of property, plant and equipment are classified as part of assets under construction.

Finance expenses in respect of specific and general borrowings are capitalised against qualifying assets as part of assets under construction. Where funds are borrowed specifically for the purpose of acquiring or constructing a qualifying asset, the amount of finance expenses eligible for capitalisation on that asset is the actual finance expenses incurred on the borrowing during the period less any investment income on the temporary investment of those borrowings.

Where funds are made available from general borrowings and used for the purpose of acquiring or constructing qualifying assets, the amount of finance expenses eligible for capitalisation is determined by applying a capitalisation rate to the expenditures on these assets. The capitalisation rate of 8,0% (2025: 7,4%) is calculated as the weighted average of the interest rates applicable to the borrowings of the Group that are outstanding during the period, including borrowings made specifically for the purpose of obtaining qualifying assets once the specific qualifying asset is ready for its intended use. The amount of finance expenses capitalised will not exceed the amount of borrowing costs incurred.
