ACCIONA, S.A. AND SUBSIDIARIES (Consolidated Group ...

- The results for tax purposes of the various Group companies that will be reported to the
tax authorities in the future that served as the basis for recognising the various income taxrelated
balances in the accompanying consolidated financial statements.
These estimates were made on the basis of the best information available at 31 December 2011
and 2010 on the events analysed. However, events that take place in the future might make it
necessary to change these estimates. Any such changes would be made in accordance with the
requirements of IAS 8.
3.4 Changes in accounting estimates and policies and correction of fundamental errors
- Changes in accounting estimates: the effect of any change in accounting estimates is
recognised under the same income statement heading as that under which the expense or
income measured using the previous estimate was recognised.
- Changes in accounting policies and correction of fundamental errors. The effects of changes
and corrections of this kind are recognised as follows: if material, the cumulative effect at the
beginning of the year is adjusted under “Reserves” and the effect for the current year is
recognised in the income statement. In these cases, the financial data for the comparative year
presented together with those for the current year are restated.
At 31 December 2011 and 2010, there were no significant changes in accounting estimates or
accounting policies or corrections of errors.
