Investments arising from environmental activities are valued at their original cost and capitalised as increases in the cost of fixed assets or inventory in the financial year in which they are incurred.

Any expenses arising from environmental protection and improvement are recognised in the consolidated comprehensive profit and loss statements for the year in which they are incurred, irrespective of the moment when the cash or financial flows deriving from them arise.

Provisions for likely or certain liabilities, ongoing litigation and outstanding indemnities or obligations of an indeterminate amount connected with the environment and not covered by the insurance policies taken out are established at the time the liability or obligation linked to the indemnities or payment arises.
