The Group receives tangible fixed assets constituting electricity infrastructure free of charge. Until 31 December 2009 such transactions were recognized at fair value as property, plant and equipment, and their value was recognized under deferred income and settled over time in the profit or loss pro rata to depreciation costs accrued on the received assets. Since 1 January 2010 fixed assets constituting electricity infrastructure received free of charge are recognized in full amount as revenue in profit or loss.
Other subsidies received by the Group (i.e. grants in the form of other fixed assets and compensation for expenses incurred for other fixed assets) are recognized by the Group in the statement of financial position as deferred income when there is reasonable assurance that they will be received and that the Group will comply with appropriate conditions related to such grants. Grants received as compensation for costs already incurred by the Group are recognized on a systematic basis as revenue in profit or loss in the periods in which the entity recognizes as expenses the related costs. Grants received by the Group as compensation for capital expenditure incurred are recognized on a systematic basis in proportion to the depreciation charges as other operating revenue in profit or loss over the useful life of an asset.
