(2) Basis of preparation

Presentation in thousands of euros

The financial statements are presented in thousands of euros.

Historical cost

The financial statements are based on historical cost, unless otherwise stated.

Going-concern basis

The financial statements were prepared on a going-concern basis.

Estimates and assumptions

The preparation of the financial statements in accordance with EU-IFRS requires management to make judgements, estimates and assumptions that affect the reported amounts of assets and liabilities and of revenue and expenses. The estimates and their underlying assumptions are based on experience and other factors that are considered reasonable. The estimates form the basis for calculating the carrying amounts of assets and liabilities that cannot easily be derived from other sources. Actual results could differ from these estimates. See also note 6.30, Management estimates and judgements.

Changes in accounting policies

The estimates and underlying assumptions are continually reassessed. Revised estimates are recognised in the period in which the estimate was revised, provided that the revision only affects that period. Revisions are recognised in the reporting period and future periods if the revision also affects future periods.

The accounting policies described below have been consistently applied to all periods presented in these consolidated financial statements and to all entities in the Group.
