In accordance with current legislation, Ibersol’s tax returns are subject to review and can be corrected by the tax authorities for a period of four years in general terms, so the returns for 2021 to 2024 are still open. Ibersol’s management believes that corrections resulting from reviews or inspections by the tax authorities of these tax returns will not have a significant effect on the fi- nancial statements presented on 31 December 2024. 509
