Share Premium [Abstract] |
Share premium | Share premium Share premium includes the amount paid up by the Bank’s shareholders in capital issues in excess of the par value. The Corporate Enterprises Act expressly permits the use of the share premium account balance to increase capital at the entities at which it is recognised and does not establish any specific restrictions as to its use. The change in the balance of share premium corresponds to the capital reductions detailed in note 31.a). The decreased produced in 2023 by an amount of EUR 1,595 million was the consequence of the difference between the purchase value of the redeemed shares (EUR 1,900 million) and the par value of said shares (EUR 305 million) (see note 4.a and consolidated statements of changes in total equity) as a consequence of the capital decreases described in note 31.a. The decrease produced in 2024 by an amount of EUR 3,778 million was the consequence of the difference between the purchase value of the redeemed shares (EUR 4,294 million) and the par value of said shares (EUR 516 million) (see note 4.a and consolidated statements of changes in total equity) as a consequence of the capital decreases described in note 31.a. The decrease produced in 2025 by an amount of EUR 3,055 million has been the consequence of the difference between the purchase value of the redeemed shares (EUR 3,287 million) and the par value of said shares (EUR 231 million) (see note 4.a and consolidated statements of changes in total equity) as a consequence of the capital decreases described in note 31.a. Likewise, in accordance with the applicable legislation, a reserve has been provided in 2024 for amortized capital charged to the issue premium for an amount equal to the nominal value of said amortized shares ascending to EUR 231 million (EUR 516 million and EUR 305 million euros in 2024 and 2023 respectively).
