Annex

Comparative information Following the adoption of IFRIC 21 on levies by the IFRS interpretations Committee, in 2014 there was a change in accounting policy with respect to contributions made to the Deposit Guarantee Fund. According to the International Accounting Standards said change has been applied retroactively restating certain amounts presented for comparative purposes from prior year. The main effect of this change is that, with respect to the income statement for the year 2013 previously published, the balances for the following line items have been modified: "Other Income and Expenses" and consequently the line items of "Gross Margin", "Operating income", "Operating Profit & Loss before tax" and "Profit attributable to parent company". Therefore, the "profit attributable to parent company" for the year 2013 becomes €2,084 million compared to €2,228 million registered under the previous regulation. Additionally, the Group's total equity in 2013 would change from €44,850m published with the previous regulation to €44,565m. However, for the purposes of the explanations contained in this quarterly report, the information for 2013 remains unchanged and as previously published, to isolate the effect of said change in the trends of the year-on-year variations of the different margins.
