Other property, plant and equipment are recognised at cost less accumulated depreciation and accumulated impairment losses. Depreciation is done using the straight-line method.
For individual groups of fixed assets, the following useful lives have been adopted:
| The Group |
Total useful lives |
| Buildings | 25-60 years |
| Technical equipment and machines | 4-15 years |
| Motor vehicles | 3-14 years |
| Other fixed assets | 5-10 years |
Intangible assets presented as “other intangible assets” include in particular: acquired property rights not related to mining operations and software. These assets are measured at cost less any accumulated amortisation and impairment losses.
Intangible assets are amortised using the straight-line method over their anticipated useful lives. The useful lives of the main groups of intangible assets are as follows:
| The Group | Total useful lives |
| Acquired property rights not related to mining activities | 5-50 years |
| Software | 2-5 years |
| Other intangible assets | 40-50 years |
