In application of IFRS 3, “Business combinations”, goodwill is the difference between:
When this difference is negative it is immediately included in net income.
The fair values of assets and liabilities and the resulting goodwill are finalised within twelve months of the acquisition.
Goodwill on acquisition of subsidiaries is disclosed separately in the balance sheet. Impairment on this goodwill is reported under the heading “Impairment” in the income statement. After initial recognition, goodwill is carried at cost less any impairment recognised.
Goodwill on acquisition of associates and joint ventures is included in the investment’s net book value. Impairment on this goodwill is included under the heading “Share in income of associates and joint ventures”.
Goodwill is not amortised, but impairment tests are carried out as soon as there is an indication of possible loss of value, and at least annually, as described in note 1.3.14.
Research expenses are recognised as expenses in the financial period incurred.
Development costs that qualify for capitalisation under IAS 38 are included in intangible assets and amortised on a straight-line basis over their foreseeable useful life.
Other intangible assets mainly comprise:
The Group applies IFRS 6, “Exploration for and Evaluation of Mineral Resources”.
Prospection and exploration costs and costs incurred in connection with geological surveys, exploration tests, geological and geophysical mapping and exploratory drilling are recognised as intangible assets and fully amortised in the year they are incurred.
Development costs related to commercially viable mineral wells and investments in facilities to extract and store hydrocarbons are recognised as “Property, plant and equipment used in generation and other tangible assets owned by the Group” or “Property, plant and equipment operated under concessions for other activities” as appropriate.
They are amortised under the Unit Of Production (UOP) method.
This concerns discontinued E&P operations (see note 2.3).
The Group’s property, plant and equipment is reported under three balance sheet headings, as appropriate to the business and contractual circumstances of their use:
Property, plant and equipment is recorded at acquisition or production cost:
When some of the decommissioning costs for a plant are to be borne by a partner, the expected reimbursement is recognised as accrued income in the assets. The difference between the provision and the accrued income is recorded in Property, plant and equipment, and subsequent payments by the partner are deducted from the accrued income.
The Group capitalises safety expenses incurred as a result of legal and regulatory obligations sanctioning non-compliance by an administrative ban from operation.
Strategic safety spare parts for generation facilities are treated as property, plant and equipment, and depreciated over the residual useful life of the installations.
The costs of operations that are necessary for generation assets to remain in service, and are undertaken at the time of scheduled shutdowns, particularly during major inspections, are capitalised and amortised over a period corresponding to the time elapsing between two inspections.
When a part of an asset has a different useful life from the overall asset’s useful life, it is identified as an asset component and depreciated over a specific period.
