41. Provisions for dismantling fixed assets, restoration of land and other provisions

Provision for mine decommissioning costs

The provision for costs of dismantling fixed assets and restoration of land includes mainly the provision for costs of decommissioning of mines for which it is required that the assets be liquidated and the land restored to its original condition after the exploitation.

The provision is determined based on future decommissioning costs and costs of land restoration estimated by independent experts taking into account the discounting effect and the amount determined in line with separate regulations of the Mine Decommissioning Fund. The provision is estimated based on an analysis prepared using deposit exploitation projections (for mines) and a technical and business analysis.

For coal mines a corresponding entry is made in line with IAS 16 Property, Plant and Equipment as a fixed asset of a mine and changes in estimates are disclosed in line with IFRIC 1 Changes in Existing Decommissioning, Restoration and Similar Liabilities, i.e. as adjustments to the provision and capitalised future mine decommissioning costs. The unwinding of discount is recognised in the profit or loss.

Provision for restoration of land and dismantling and removal of fixed assets

Based on estimates of future costs of dismantling prepared by independent experts, taking into account the discounting effect, the Group establishes a provision for estimated costs of dismantling, to include those related to wind farms, but also for removing fixed assets and restoring the land where the fixed assets were located if it has an obligation arising from the acquisition or use of property, plant and equipment items.

PROFESSIONAL JUDGEMENT AND ESTIMATES

The Group estimates the amount of provisions created based on the assumptions, methodology and calculations appropriate for a given type of provisions, evaluating the probability of spending funds that incorporate economic benefits and determining the reliable level of funds necessary to perform the obligation. Provisions are created by the Group if the probability of spending funds that incorporate economic benefits is higher than 50%.
