. Prepayment mainly affects fixed-rate 
 mortgages when their contractual interest rates are high compared to market interest rates.                                                                                                                                                       |

| – | Modelling of demand deposits and other liabilities with no contractual maturity: a model has been defined using                                                                                                                                        
 historical monthly data to reproduce customer behaviour, establishing parameters concerning the deposits’ stability, the percentage of interest rate movements that is passed through to the interest paid on the deposits and the delay with which    
 this occurs, depending on the type of product (type of account/transactionality/interest paid) and the type of customer (retail/wholesale). The model captures the effect of low interest rates on the stability of deposits, as well as the potential 
 migration to other deposits that earn more interest in different interest rate scenarios.                                                                                                                                                              |

| – | Modelling of non-performing lending items: a model has been defined that                                                                                                                                        
 allows the expected payment flows associated with non-performing positions (net of provisions, i.e. those expected to be recovered) to be included in pools of interest rate-sensitive items. To this end, both 
 existing balances and estimated recovery periods are included.                                                                                                                                                  |

The process for approving and updating IRRBB models is part of the corporate governance arrangements for models, whereby these models are reviewed and validated by a division that is always separate from the division that created them. This process is included in the corresponding model risk policy and establishes both the duties of the different areas involved in the models and the internal validation framework to be followed. As for the measurement systems and tools used, all sensitive transactions are identified and recorded taking into account their interest rate characteristics, the sources of information being the official ones of the Institution. These transactions are aggregated according to predefined criteria, so that calculations can be made faster without undermining the quality or reliability of the data. The entire data process is subject to the requirements of information governance and data quality, to ensure compliance with the best practices in relation to information governance and data quality. Additionally, a regular process is carried out to reconcile the information uploaded onto the measurement tool against accounting information. The calculation tool includes sensitive transactions and its parameters are also configured to reflect the result of the behavioural models described above, the volumes and prices of the new business, defined according to the Financial Plan, and the interest rate curves on which the aforesaid scenarios are built. Based on the balance sheet position and the market situation and outlooks, risk mitigation techniques are proposed and agreed upon to adjust this position to match the one desired by the
