The Group follows the policy of provisioning for the estimated amounts arising from ongoing litigation, indemnities or obligations, as well as for any sureties or guarantees granted by Group companies which could involve the Group in a payment obligation (either legal or implicit), provided the amount can be reliably estimated.
Provisions are quantified based on the best information available on the position and evolution of the events that cause them and are re-estimated at the end of each reporting period, being totally or partially reversed when these obligations cease to exist or decrease.
Contingent liabilities, except in business combinations, are not recognised in the consolidated financial statements, but are reported in the notes to the financial statements, in accordance with the requirements of IAS 37.
